This application is a division of Serial ~o. 161,817,
filed January 22, 1973, now Patent No. 1,013,207, dated July 5,
1977.
The invention relates to building structures and refers
more specifically to a sliding door which is esthetically pleasing,
easily operated, has weathertight integrity to both air and water,
has extremely high structural integrity and substantial universality
of components whereby the greatest degree of versatility has been
achieved from a specified inventory investment of raw material and
finished goods at a relatively low cost. In one modification, the
sliding door has been particularly structured to provide high
efficiency and economy by modification of the sliding door frame
and door panel extrusions and provision of a screen having an
extruded frame with a single cross section and unique hardware.
In the past, sliding doors have not generally included
all mitered corners. In particular, the jambs at the bottoms of
previous sliding doors have generally either been straight-cut
across the sill, or where the sill has been inclined, the jambs
have been diagonally cut, whereby a high degree of orientation
is given to the frame members of previous sliding doors which
is undesirable from an inventory and thus cost point of view.
Further, wherein mitered corners have been provided in sliding
doors in the past, no means have been provided to prevent mis-
alignment of the mitered joints on securing the members forming
the mitered joints to each other. Thus, mitered joints in the
past have required skilled workmen to produce and have often
been misaligned.

In addition, in prior sliding doors, either two pockets
formed by three fins, one pocket for each of a movable and
fixed door panel with a fin between the door panels, have
been provided in the frame head, or alternatively, three
pockets have been provided between two outer fins and two
intermediate or guide fins in the frame head for guiding
the top rails of a movable and a fixed door panel, with the
guide fins received in slots in the door panel top rails.
In both structures, considerablo weather sealing and/or fab-
rication of weather seal inter~ocks on the door panels has -
been necessary. Again, the added weather sealing and fabrie ``
cation together with the orientation which the fabrication
and/or weather sealing require has given the components of
and the finished door panels thus constructed has added an
undesirable cost factor and inventory requirement to prev-
ious sliding doors.
Further, previous sliding doors have usually not been
suitably weathertight without expensive and sometimes compli-
cated structure. Thus, for example, a complete aluminum
s~rD~nd has often been provided in the past for glaiing
sliding door panels from the inside to prevent popping of
the glazing panels out of the frame therefor under high wind
loads. Complicated structure has sometimes been required
to prevent entire slid~ng door panels from being blown out
of the outer frame therefor.
In addition, with prior sliding doors, stopping of
the sliding door on opening has sometimes been a problem.
Wherein stops have been provided only at the tops or bottoms
of the movable door panel, the door panel tends to cock in
the
-2-
105'~6'Z7
frame on hitting the sop, thus wearing door panel rollers
and damaging the outer frame or movable door panel. Prior
stop structures have in addition also required separate
fabrication of the frame member to install and sometimes
themselves have b~en complicated and therefore expensive.
Central stops have in general not been utilized dur to their
appearance and the fact that they tend to damage the door
and/or frame members due to single-point contact, therewith
centrally thereof.
FuPther, with prior sliding doors it has often been
possible on jiggling the movable door panel to unlock it and t~ -
ga~n entrance into the bui~ding in which the doors have been
installed. It has generally been impelsible with sliding
doors to lock the movable door panel in a partly open
position to provide, for example, venti~ation without allow-
ing smallchild~n to go out or prowlers ~o come in the doors.
Also, it has been difficult in the field, with the size
of sliding doors usually installed today, to obtain square
structurQl openings for the sliding door structures. It
has therefore been necessary to adjust the movable door panel
of slid~ng doors to compensate for the out-of-square door
openings. In the past, such adjustment has usually been
accomplished by adjusting the movable door panel at both
sides thereof, which requires separate adjusting mechanisms
and separate adjustments which are not entirelv independent
a~ both sides of the movable door panels.
The 81 ding screen doors provided with the sl~ding
door structures of the past have usually had roll formed
frames and have been required to have deep pockets in the
upper and lower frame rails to receive adjustable rollers at
the corners of the
-3- -
105Z~Z7
screen doors. The frame members have therefore often been
of different cross section and have not always been provided
with mitered corners. In addition, in the past, screen
members have been secured to the frames in rectangular
recesses receiving either round or rectangular splines.
Such structure has not always securely held the periphery of
the screen to the fr~me. Separate handle and locking struc-
tures have usually been provided with prior sliding ecreen
doors. ~ ~
Further, in the past, sliding doors have not always .
been adapted for installation in a wide variety of building
structu*~s with a single frame, as for example, bu~`lding
structures which require nailing fins for securing the frame
to the exterior of the building structure. In addition,
nei~her interior nor exterior trim for sliding doors have
normally been readily available and extensions of slidn~g
door frame sills have in the past generally field fabrica-
ted.
In accordance with the present invention, there is pro-
vided a sldding door including an outer frame having four
mitered corners and a plurality of door panels, at least one
of which may be fixed and one ~f which is movable, which
outer frame and door panels and the individual mem~ers there-
of have been constructed with a minimum of orientation to
provide the greatest degree of versatility from a specified
inventory investment for both raw and finished goods. Thus,
where~er~ possible the me~bers of the sliding door structure
of the invention are interchangeable right-left, up-down in-
side and outside.
In one modification of the preferred embodiment of
., .
lOS'~6Z7
the invention, the members of the frame and door panels have
been constructed to provide a cross section which is effic-
ient yet particularly economical.
The mitered corners of the outer frame are provided
with integral offset abutment structure on one member
thereof adapted to engage the other member forming the
corner, whereby the corners may be quickly and accurately
aligned in assembly and tightly connected without the dan-
ger of misalignment on drawing the miter-cut members tightly
against each other.
The head of the outer frame of the sliding door
st~cture disclosed is provided with a single guide fin for -
guiding a movable door panel and no fin is positioned between
the movable door panel and the fixed door panel, whereby ~ ~
weather sealing of the door panels is particularly simple ! : . '
and efficient. Hairpin shaped top guide members are provided ~- -
between the top of the movable door panels and ~uide fins.
Unique weather seals are provided at both the upper and
lower railæ of both the movable and fixed panels of the sldd- -~
ing door structure which ~lso aid in maintaining the struc-
tural integrity of the sliding door.
Further, in one modification of the preferred embodi-
ment, the fixed ~oor panel of the sliding door structure
of the invention is retained at its fixed side rail in
assembly with a jamb of the outer frame by staked-out portions
therein. The other or free side rail of the fixed door panel
of the sl~ g door structure may be secured to the sill by
a weather stop bracket to enable the sldding doDr structure
to withstand very high winds.

In another modification of the sliding door structure
of the invention, the fixed door panel may be retained at its
fixe!d side rail in assembly with a jamb of the outer frame by
screws extending through the jamb of the frame and into the fixed
side rail of the fixed door panel. In either modification, the
top rail of the fixed door panel may be secured to the head of
the outer frame by screws.
Further, a two-member glazing system is provided for the
door panels in one modification of the preferred embodiment of the
invention which enable the glazing panels to withstand very high
wind pressures and permit glazing of the door panels from the in-
side of a building in which the sliding door is installed.
Sliding screen door structure is provided in the sliding
door structure which is completely reversible end for end, inside
for outside and left to right comprising head, jamb and sill frame
extrusions secured together at their ends into a rectangular frame
defining a flat plane. Each of the extrusions of the frame in-
cludes a cross section comprising an inner and outer rectangular
portion separated by a solid web portion, which cross section has
a center line extending centrally of and parallel to the web por-
tion within the web portion. The sliding screen door structure
further includes a screen member and means securing the periphery
of the screen to the frame centrally of the plane of the frame
and parallel to the plane of the frame substantially midway be-
tween the inside and outside of the screen door immediately
adjacent the center line of the cross section of the frame extru-
sions. The sliding door structure also includes a unique bumper
system and separate prowler lock structure and modifications
thereof.
` 1(~5'~6~7
To compensate for out-of square door openings in in-
stallation, the movable panel of the sliding door is positioned
on an expander and a wedge and a wedge block are secured to the
expander and to one edge of the movable panel of the sliding door
structure respectively, having engaged, inclined plane surfaces
for pivoting the movable panel in the plane of the movable door
panel about one edge thereof. The wedge is constructed to fit
within the expander at two different levels to provide coarse
movable panel adjustment. Fine adjustment of the panel is pro-
duced by relative movement of the wedge and wedge block. Wedgeand wedge blocks may be provided at one or both edges of the
movable door panel.
The sliding screen door structure of the invention may
be utilized outside of the sliding door structure with which it
is disclosed and is completely reversible end for end, inside for
outside and left to right and includes head, jamb and sill frame
extrusions secured together at their ends into a rectangular frame,
each of which extrusions has a cross section comprising an inner
and outer rectangular portion separated by a solid web portion,
which cross section has a center line extending centrally of and
and parallel to the web portion within the web portion, a screen
member, and means for securing the periphery of the screen member
to the frame centrally of the plane of the frame and parallel to
the plane of the frame substantially midway between the inside
and outside of the screen door immediately adjacent the center
line of the extrusion cross sections.
In a more economical modification of the preferred em-
bodiment of the sliding door structure, the screen frame members
are extrusions and are provided with unique spring loaded adjust-
able roller assemblies at all four corners thereof which do
.-,
105~ '7
n ot require deep upper and lower rail cross sections. The screen
s,' , ~
frame extrusions of this modification are also constructed to el- -
iminate the necessity of separate screen handles and to facilitate
loc~ing of the screen to the sliding door structure outer frame by
particularly simple lock structure and to receive the periphery of
the screen member in a recess having the cross section shape of a
parallelogram, which recess is operable in conjunction with a
similarly shaped spline to more securely hold the periphery of the
screen member
The sliding door structure of the invention is ~mpleted
with a nailing fin adapter for securing the outer frame in building
openings requiring nailing fins. Inside trim extrusions such as
resilient bullnose sections adapted to accommodate flooring of
different thickness, and exterior trim members including members
having a soft core and harder exterior skin are also provided for
use in conjunction with the sliding door structure, along with a
sill adapter for extending the width of the sill of the outer frame
of the sliding door structure. In sliding door structure having
two movable door panels, a unique astragal adapter is secured to
the locking rail of one movable door panel for receiving the lock-
` ing rail of the other movable door panel with the movable door
panels in a closed position.

The first modification of the preferred embodiment of
the sliding door structure 10 shown in Figure 1 includes an
outer frame 12, a fixed door panel 14, a movable door panel
16 and a movable screen panel 18. The sliding door structure
10 may have a plurality of fixed and/or moving door panels.
Thus, the invention is not intended to be limited to sliding
doors having a single fixed door panel and a single movable
door panel.
As shown, the outer frame 12 includes a header or head
extrusion 20, jamb extrusions 22 and 24 at opposite sides
of the
-13-
1052~iZ7
sliding door structure 10 and a sill extrusion 26, which
extrusions have the cross sections best shown in Figures 2
and 3. Each of the four corners of the outer frame 12 are
mitered as shown in Figures 27 through 29 and may be held
together by suitable screw means 25. With all four cornera
being mitered, the ~ambs are universal in that they have
no left, right, up or down orientation.
To air in securing the mitered corners of the frame
12 together inthe desired alignment, one or more portions 31
of the jambs 22 and 24 at the ends thereof are offset or de- -
pressed as shown hest in Figure 28 to provide an end abut-
ment 33 against which the side of the web 35 of the head 20
and a similar portion of the sill 26 are urged by the screw
means 25 extending into the screw runners 37 in the jambs 22
and 24 in assembly of the frame 12. With such struc*ure,
the mitered members at the four corners are not permitted to
slip past each other along the miter joint as might other-
wise happen if the securing screw means 25 are dr~wn too
tight. The mitered corners of the frame 1~ m~y thus be
accurately constructed by relatively unskilled workmen. It
will be understood that the miter joint aligning concept
embodied in the abutting portions formed in the jambs is
not limited to extrusion structures.
The fixed door panel 14 includes a fixed door panel
frame 28 having a top rail 30, a bottom rail 32 and free
and fixed side rails 34 and 36 respectively, again~ having
the cross section shown best in Figures 2 and 3. The side
rails 34 and 36 extend the entire length of the fixed door
panel as shown best in Figure 1 and are secured to the top
and bottom rails 30
-14-
lQ5'~Z7
and 32 at opposite ends thereof by suitable means such as
scre~s or the li~e. A glazing panel 38 is secured in the `~
fixedi door panel frame 28. Each ~f the top, bottom and side
rails of the fixed door panel 14 is also substantially
univ~rsal in that they have as little orientation as possible
so that the complete panel 14 as well as the individual
members thereof may be used for different sliding door con-
figurations.
The sliding door panel 16 includes a top rail 40, a
bottom rail 42 and locking and free side rails 44-~and 46,
respectively. Also as before, the side rails 44 and 46 ext-
end the full length of the movable door panel 16 and are
connected to the top rail 40 and bottom rail 42 at the op-
posite ends thereof as shown best in Figure 1. The glazing
panel 48 is secured in the movable door panel 16 as before
and all of the members of the movable panel 16 are construc-
ted without particular orientation when possible so as to
be interchangeable.
Thus, the sliding door structure 10 may be cDnstructed
in a great number of configurations with a minimum of sep-
arate parts such as frame jambs and panel rails and the like,
and a complete inventory of sliding doors may be stocked,
again with a minimum of separate sliding door elements such
as exte~ior frames, fixed snd moving panel. The cost of a
sl~ing door inventory and production equipment and facilit-
ies is thus reduced.
The screen structnre 18 shown in Figure 1 includes the
frame 50 having a top rail 52, a bottom rail 54 and side
rails 56 and 58. A screen 60 is secured within the frame
50 by convenient means such as a peripheral recess 62 in
the rails having
-15-
105Z627
screen retaining members 64 positioned therein. Rollers 66
are mounted in the top and bottom screen frame rails and run
on tracks 68 and 70 in the frame head 20 and s$11 26 as shown.
Suitable handle structure 72 and latch structure 74 are pro-
vided for moving the screen structure 18 in the plane of the
frame 12 and retaining the screen in a closed position over
the opening provided by the movable door panel 16, respectively.
The head 20 of the door frame 12 has a cross section
shown best in Figure 3 which includes an outer fin 76 and an
inner fin 78 which are only outside and inside trim in the door -
structure 10. A fin 80 which is a seal for the fixed door panel
14 is positioned between th~ outer fin 76 and the inner fin 78 `
and separates the pocket 82 in which the screen panel 18 is
received and the pocket 84 in which the top rails 30 and 40 of
the fixed door panel 14 and the movable door panel 16 are
positioned. A guiding fin 86 is further provided in the pocket
84 for guiding the movable door panel 16 within the frame 12.
Since the head 20 does not include a separate fin
positioned between the top rails 30 and 40 of the fixed and
movable door panels, no special fabrication of the interlocking
portions of free side rails 34 and 46is required and removable
interloking portions to facilitate universal orientation of
the free side rails is not required. Similarly, since only the
movable door panel 16 is provided with a guiding fin 86, spec-
ial weather stripping to prevent the passage of wind and water
through the door structure 10 between the head 20 and the top
rails 30 and 40 is minimi7ed and uncomplicated.
Thus, the fixed door panel 14 is provided with an
105'~627
elong~ted sealing member 88 at the top rail 30 having the cross
section shown best in Figure 3. The sealing member 88 performs
the dual function of providing structural integrity at the top
of the flxed door panel 14 between the head 20 and the top rail
30 and seals the top of the fixed door panel. As shown, the
sealing member 88 has a generally S-shaped cross section con-
figuration, one portion of which fits over the top of one side
portion of the top rail 30 and the other portion of which fits
over the bottom of the head fin 80.
An identical sealing member 90 is provided at the
bottom rail of the fixed door panel 14 and as shown best in
Figure 3 includes a portion fitting over one side portion of
the bottom of the bottom rail 32 of the fixed door panel 14
and another portion fitting over the rib 92 on the frame sill
26. Again, the sealing member 90 provides structural integrity
between the frame 12 and fixed door panel 14 at the same time
that it provides a seal for the sliding door structure 10.
Alternatively~ the sealing member 94 illustrated
best in Figure 5 may be used in place of the sealing member 90.
20~ When the sealing member 94 is used, the structural integrity
of the fixed door panel 14 at the bottom is provided primarily
by the weight of the door panel 14 resting on the sill 26
between the ribs 92 and 96. The member 94 functions primarily
as a weather seal.
The sealing of the fixed door panel 14 between the
fixed side rail 36 and the fram jamb 24 is accomplished by
means of a flexible sealing strip 98 which may be of vinyl,
felt or the like in contact with the fin 100 of the frame jamb
-17-
.
105;~62'7
24 as shown be~st in Fi~ure 2. In addition, the structural
inte~rity of the side rail 36 with the jamb 24 is maintain~d
by the staked-ou-t portions 10~ of the sid~ ràil 3G fitting
behind the returned end portion o~ -the fin 104 of the jamb 24.
If desired, the side rail 36 may be secured to the jamb 2~ by
separate screws, clips or the like in keepin~ with present
conventional construction.
In assembly, the sealing members 88 and 90 or 94 are
positioned on the fix~d door panel 14 and the door panel 14 is
positioned in the frame 12 by first placing the fin 80 in the
seal 88 and pivoting the fixed door panel 14 inwaraly of the
frams 12 at the bottom ~hile movin~ the fixed door panel 14
.
upward so that the bottom rail 32 clears the track 70 and rib
92. When the door panel 14 is thus positioned in the frame 12,
the door p~nel l~ is allowed to drop vertically slightly to
position the seal 90 or 94 over the rib 92.
The fixed door panel 14 is then moved toward the
frame jamb 24 to cam the staked-out portions 102 of the side
rail 36 of the fixed door panel 14 into the jamb po~k~t 106,
, .
whereby the sealing strip 98 is positioned in contact with th~
fin 100 of the jamb 24 and the fixed rail 36 is locked in
assembly with the^jamb 24. Removal of the fixed door panel 14
then requires the placing of~a screwdriver or the li~e between
the fin 104 and rail 36 to spring the fin 104 and permit the
staked-out portions 102 of the rail 36 to be removed from -the
jamb 24~ Such removal of the fixed door panel can only be
accomplished from the inside of the door.
Th~ fixed door~panel 14 and the movable door panel 16
.. , .,, ~ . - . .. .... . .. ~ . _
~052627
are sealed at the interlocking portions of the free side rails
thereof by the flexible strips 108 and 110 positioned in the
sidle rails 34 and 46 as shown best in Figure 2. :Similarly, the
locking side rail 44 of the~movable door panel is sealed in the
pocket 112 of frame ~amb 22 with the movable door panel 16 in a
closed position by the flexible strip 114. Strips 108~ 110 and
114 may be vinyl, felt or similar material. As shown, a s~it-
able handle 116 and lock structure 118 are also secured to the
locking side rail 44 of the movable door panel 16 and the frame
jamb 22.
The-bottom of the movable door panel 16 is sealed by `
a sealing member 122 having a cross section illustrated best in
Figure 3 and extending from the side of the movable door panel
expander 124~ which will be considered subsequently. It will
be noted that the sealing member 122 extends toward the outside
slde of the sliding door structure 10 whereby wind pressure on
the door structure 10 increases the seal provided by the sealing
member 122.
The top rail 40 of the movable door panel 16 is pro-
vided with a weather seal by the dual durometer sealing member126, the cross section of which is shown best in Figure 4. The
portion 128 of the sealing member 126 is of relatively rigid
plastic which is flexible enough to be snapped in place over
the rib 130 on the head 20 of the frame 12, with the opposite
end thereof being constructed to cam over and receive the end
of the fin 80 of the head 20. Thus, the sealing member 126 may
be positioned within the pocket 84 in the head 20 of the frame
12. With the sealing member 126 so positioned, the softer, more
-19-
1052~27
pliable portion 134 of the sealing member wipes against the
upper rail 40 of the movable door panel 16 to provide a seal
therefor.
Thus, both the fixed door panel 14 and the movable
door panel 16 are completely sealed around their entire peri-
phery when the movable door panel is closed, with a minimum
number of simple sealing members. In addition, the sealing
system does not orient any of the frame or door panel members
so that they are a8ain as universal as possible whereby the
sliding door structure of the invention may be produced with
a minimum inventory. At the same time, due to the single
guiding fin provided in the head member 20 and the deletion
of a separating fin between the fixed and movable door panels
in the head 20, the unique sealing ~embers 88, 92 or 94, 122
and 126 provided, a more efficient and less expensive sealing
system for the sliding door structure 10 than has been avail-
able in the past is provided.
Should the sliding door structure 10 shown in Figure 1
be installed in areas where extremely high winds of for example
hurricane velocity may be expected, a weather stop bracket 136,
shaped as shown best in Figure 6, is provided at the bottom of
the free rail of the fixed door panel 14. In installation, the
open end of the fixed door panel free side rail 34 is positioned
over the rectangular portion 138 of the bracket 136 and posi-
tioned within the grooves 141 in the part 142 of bracket 136.
A screw 140 is used to secure the bracket 136 to the sill 26.
In addition to the weather stop 136, the side rail 36
may, if considered necessary, be secured by a screw centrally
thereof to the fin 100 of jamb 24~ and the top rail 30 may be
-20-
,oS;~
ecured by a screw to the fin 80 of the head 20 ~djac~nt the
free side rail 34. With such ad~itional structul-e, the sliding
door ~tructure 10 can withstand extremely high winds of hurri-
cane velocity.
As shown best in Figure 7, the upper corners of the
sliding door structure 10 are provided with a weather stop and
prowler security member 144. The me~er 144, which is shown
in perspective in Figure 8, includes the triangular fin portion
146 adapted to complete the guide fin 86 of the head 20. The
fin 146 is necessary due to the mitered corner and the provision
of the fin 86 on the head 20 without a similar fin on the jamb
members 22 and 24.
In addition, the member 144 is provided with the
rectangular portions 148 and 150 which extend across the pocket
112 in the jamb 22. The member 144 is spaced in the pocket 112
by the projections 152 and 154 thereon. The flanges 156 and
158 aid in retaining the member 144 in position at th2 top of
the jamb members 22 and 24 with the upper portion o~ the fin 86
in the slot 160 between the portions 148 and 150. When in-
stalled on the head 20, member 144 also aids in the alignment
of the mitered upper corners of frame 12 in field assembly of
; the frame.
In use, the member 144 also serves to prevent upward
jiggling of the movable door panel 16 and consequent unlocking
of the latching mechanism by prowlers or the like. Thus, with
the movable door panel 16 close~, the top of the locking side
rail 44 will engage the bottom side of the portions 148 and
150 to prevent undesired upward movement thereof.

A simila~ function may be accomplished ~ cut-out and
folded-do-~ rectangular portions such as portions 151 and 153 in
the hlead 155 of the frame 157 shown in Figure 14. Such cut-out
and folded-down portions may be provided anywhere along the
length of the head 1~7 where they are desired, but will most
uqually be spaced out across the opening provided in the sliding
door structure by tlle open movable door panel.
Bumpers 154 as shown best in Figure 7 are provided at
the top and bottom of jamb 24 to prevent damage to the movable
door panel 16, rollers secured thereto and/or the frame 12 due
to rapid opening of the movable door panel 16 and/or coc~;ing of
t~e movable door panel 16 which might occur on engagement of the
~ovable door panel with a single bumper 164 at either the head
or sill of the frame 12. Thus, separate stop members 164 are
positioned both on the rib 130 of the head and on the track 166
of the sill so that they enyage the free rail 46 of the movable
door panel 16 as the door panel approaches a fully open position.
The bumpers 164 have the cross section illustrated in Figure 7
and are provided with a slot 166 so that no fabrication of the
~; 20 head 20 or sill 26 is necessary to install the bumpers 164.
The triangular member 168 is provided at the bottom of
the frame jambs 22 and 24 to close the bottom of the mitered
~ambs at the jamb fins 104. Fins 104 include the portion lOS
- which wraps around the top of a member 168 and fits within the
offset 170 in the top of the triangular member 168 as shown in
Fiqure 9. Before being inserted in the ends of the fins 104 at
the bottoms of the jamb m~mbers 22 and 24, the triangular mem-
bers 168 may be secured in position on sill 26 by means of

screws or the lik~, where~y the members 16~ align the bo~to~
mitered corners of the frame 12 in field assembly.
The glazing members 174 illustrated in Figures 1-3
can withstand high wind loads on the glazing panels 38 and 48.
However, such channcl type gl~zing is expensive and requires
that the panels be removed and disassembled for re~lazin~.
Therefore, since interior glazing of sliding doors is desirable,
as for exan~ple in apartment buildings and the like, d~-or panel
top, bottom and side rails having a glazing cross section con-
figuration such as that illustrated in Figure 15 including the
recess i76 are provided. Such rails in conjunction with the
~lazi~g members 180 and 182 or 184 illustrated in Figures 15
and 16 provide a very high wind rcsistant glazing system which
may be installed from tha inside of the sliding door and will
accommodate substantially the full range of glazing panel
thickn~sses from thin, single strength to thicker insulating
glazing panels at a moderate cost.
With the glazing systnm illustrated in Figure 15, a
glazing panel such as panel 186 is positioned in the door panel
opening against the glazing flange 188. The glazing member 180
having the L-shap_d cross section having the leg 190 and the
leg 192 is positioned in the recess 176 with the leg 190 as shown
within the recess. A glazing member 182 or 184, dopending on
the thickness of the glazing panel 186, is inserted between the
gla~ing panel 186 and the portion 192 of the glazing member 180
with the projection 194 on the member 180 extending within the
recess 196 in the member 182 or 184.
The modi~ied glazing membcr 191 as shown in Figure 17
-23-
~05'~627
is a dual durometer mcmber having a relatively hard portion ~93
simil.ar to the L-shaped glazing member 180 and a relatively soft
porti.on 195 similar to the glazing member 182. The portions 193
and 195 of the glazing member 191 are connected by the relatively
soft, flexible porti.on 197. In inst~llation, the L-shaped por-
tion 193 of the ~lazing member 191 is ins~alled in the recess 176
in the rails of a door panel and the portion 194 is rotated
counterclockwise into the position shown for glazing member 182
in Figure 15. Tlle advantage of the dual durom.eter glazing
member 191 is a saving in extrusion time, since only one extru-
sion need be made, and in cutting and assembly time, since only
one glazing member 191 need be cut to len-~th and handled.
The modified dual durometer gla~ing strip 199 illus-
trated in Figure 18 has a relatively hard, L-sh~ped portion 201
and the relatively soft portion 203 connected by a frangible
portion 205. In assembly of the glazing member 199, th~.L-shaped
portion is positioned in recess 176 and the portion 203 is forced
between the L-shaped portion 201 and the glazing panel 186.
. To facilitate movement of the sliding door panel along
the guide fin 86 without galling the guide fin 86 or causing
objectionable noise due to metal to metal scraping between the
-- ~ movable.door panel 16 and the guide fin 86, the moving panel
- top guide 200 as sho ~ best in Figure 10 is provided. The top
guide 200 is provided with a hairpin shaped portion 202 wnich
fits within a slot 204 in the upper end of the side rails 44
and 46 of the movable door panel 16 as shown in Figure 3. Thc
hairpin shaped portion 02 o~ the top guide 200 includes a
slot 206 in which the guide fin 86 is slidably received and a
-24-
105;~6Z7
flan~e 20R which aids in securing the men~er 200 in the ~lot''
'204. The top ~uidc 200 is provided with the extension 210
havinlg the spacing structure 212 on the ends thereof whereby
with th- top guide 200 in position at the ends of the top rail
40, the slot 20G is position~d centra].ly of the top ra,il.
A modified moving panel top guide 214 is illustrated
in Figure 11. The structure 214 is ayain provided with a hair-
pin portion 216 for receiving the fin 86 and adapted to be held
within the slot 204. A flexible extension 218 is provided on
one side of the hairpin portion 216 which engages the side of
the guide fin 86 in asse~bly and prevents jiggling of the mov-
able door panel 16 transverse of the door panel in operation.
With the larg~r size sliding doors today, it is un-
uqual to find a building opening for a door which is exac~ly
square. Thus, adjustment of the movable door panel 16 is
normally required to provide a desired fit within the frame 12,
the members of wh,ich are secured in the building openi.ng and to
some extent follow th~ irregularities of the building opening.
The structure shown in Figure 12 provides adjustment
of the moving door panel 16 by pivoting the moving door panel
about the bottom of the locking rail on vertical adjustment o~
: the free rail side thereof., The adjustment of the ~ovable door
panel 16 is accomplished'through the use of expander 124, a
wedge 236 adapted to fit within the expander 124, and a wedge
block 238 secured within the side and bottom rails 46 and 42
of the door panel 16 in engagement with the wedge 236. In
operation, the wedge'236 and the wedge block 238 provide an
adjustment great enough so that the adjustment of only one
-25-
105~
side of th~ movable doo~- panel 16 is normally required.
As shown, the ~edge having the flanges 240 and 242
thereon fits within the expander 124 ~-ith the inclined plane
portion 24~ extending throu~h the slot 246 therein and with
the Elanges 240 and 242 resting underneath ana on top of the
ribs 248 and 250 in the expander 124, respectively. The wedge
block 238 shaped as shown best in Figure 19 is secured to the
side rail 46 by the screw 252 and ~x~ends within the bottom
rail 42 with the inclined plane surface 254 in engag2ment wit~
the inclined plane surface 244. The adjusting screw 256
extends through the slot 258 in the side rail 46 of the movable
aOo~ panel 15.
Thus, in operation, on ad~ustment of the position of
the wedge 236 longitudinally in the expander 124, the side rail
46 of the movable door panel 15 is adjusted vertically to pivot
the door p~n,el 16 in the plane thereo~ about the bottom of the
locking side rail. The movable door panel 16 is thus adjusted
relative to the expander 124 which carries the rollers 260 ~or
~ the movable door panel 16 and carries the weather strip member
122 on the side thereof. The movable door panel 16 is thus
adjusted to me2t any o~t-of-squareness of the frame 12 ~ithout
disturbing the rollers or the weather seal at the bottom of the
~, door.
In addition, the use o~ the e~pander 124 permits
exchange of the movable ~oor panel 16 e~d for end to provide
right and left hand operation by simply removin~ the expand2r
124 and the wed~e block 238 and placing them in the other Qnd
of the movable door p~nel 16.
:
1()5~6Z7
It will also be noted that the adjustment of the
movab.l~ door panel 16 i5 accomplished with a minimum number
of parts in the simplest manner without disturbin~ the weather
tightness or structu~al integrity of the movable door panel
while preserving the lack of specific orientation of the movable
door panel.
To providc a three-step, coarse vertical adjustment
for the movable door panel 16, the wedge 236 may be positioned
with the flanges 240 or 242 on top of ribs 248 or witll flanges
242 on top of ribs 250. Additional coarse adjustment could be
provided by adding ribs intermediate ribs 248 and 250. In any
position of wedge 236, fine adjustment of the edge o~ the door
is accomplished by movement of the wedge 236 horizontal.ly with
respect to the wedge block 238 with the inclined plane portions
244 and 254 th~reo:E in surface to sur ace engagement.
Adjustmant of the other ed~e of the mo~able doo.r panel
16 i5 possible with wedges and wedge blocks at both ends of :
expander 124.
Alternatively, the web 259 of rail 46 may be offset
toward wedge 236 and used in place of wedge block 238 in con-
junction with wedge 236 to provide adjustment of the edge of ` .
the mova~le door panel 16. . -
: Another modification 262 of the-sliding door structure
of the invention illustrated best in Figures 13 and 14 is simi-
: ~ lar to the sliding door structure 10 and may in fact use an ex-
terior frame 157 which is similar to the fra{~e 12 of the sliding
door st.ructure 10 but may be of lighter and therefore more
economical cross section. The head extrusion 155, jamb extrusions
'
-27-
:~ .
. . .
1~5~ 7
264 and 266 and the sill e~trusion 268 o~ tlle frame 157 are
thus substantially the same as the head, ja~b and sill men~rs.
oE the sliding door 10 as shown in Figure 13 except for the
pxeviously consider~d tabs 151 and 152.
Similarly, the fixed and slid.ing panels 270 and 272
respectively are simil~r to door p~nQls 14 and 16. The cross
section of the rail members is however altered as shown in
Figures 13 and 14 to provide a lighter, more econor~lical and
even more universal rail ma~ber. Thus, with the rail member
cross sections illustrated in Figures 13 and 14, ~aximum strength
per unit weight and maximum universality is provided to reduce
inventory and thus cost of the sliding door structure.
As shown in Figures 13 and 14, the sliding door panels
270 and 272 utilize~the dual member glazin~ system previous.~y
considered and illustrated in Figures 15-18 to secure the glaz-
ing panels 274 and 276 in the door panels. The sliding door
- structure 262 may utilize the mitered corner joints as illus-
trated in Figures 27-29, the weathPr seal and prowler protection
structure and bumpars illustratsd in Figure 7, the weather seal
structure illustrated in Figures 4 and 9, and the top guides
of Figures 10 or 11, along with the adjusting structure for the
:~ movable door panel 272 as illustra~ed in Figure 12.
In the sliding door structure illustrated in Figur~s
13 and 14, the fixed door panel 270 is secured in position by
screws passing-through the fins 278 o-E jamb.266 and fin 280 o
head 155 in conjunction with an L-shaped bracket 282 secured
between the fixed rail 284 of the fixed door panel 270 and
sill 268 of the door structure 262.

' In addition, the modified door structure 262 of
Figures 13 and 14 in ludes the unique screen door structure 286
illustrated in detdil in Figures 19-25. The screen door struc-
ture 286 has been particularly designed for economy and
efficiency of o~eration in conjunction with the slidin~ door
structure 262 but is equally as economic~l and efficient in use
with other sliding door structures such as sliding door struc-
'ture 10.
As shown in Figure i9, the scree~ door struct~re 286 :~
includes a frame 288 having top and bottom rails 290 and 292
./ . . . ., :
and'side rails~294 and 296. The s~reen rails have a cross
section as shot~n best in Figure Z0 includL~g a first rectangular ~,
portion 298 an& a second rectang~lar portion 300 separa_sd by a
web portion 302. T~e rectangular portion,2~8 h~s a width trans-
verse of the screen door structure 286 greater than that of the
~ectangular portion 300, which rectangular portion 300 has an
open outer side 304'. , . . ',.
:,
Also, the cross section of the screen rails as shown
.
in Figure 20 includes an integral portion 306 in the shape of
a parallelogram having one open side 308 which forms a recess
in which the edge of the,screen member 310 is secured by an
~' H-shaped spline 312 having outer dim~nsions which define a
parallelogram similar to the recess 314. The inteqral parallel-
- ogram structure and the spline securing the periphery of the
screen mem~er 310 to the ~rame 288 is illustrated.best in
Figure 21.
. Such frame cross section is easily extruded and adapts
itself to being connected with a pair of corner brackets 316 and
~'' ~ ' .
.~ .
-29-
. _ , _.
. . - .
1052627
~18 at each corn2r thercoE whereby tho fram2 2~8 is particularly
sti~f. Such frame cross section also eli.minates the necessity
for separate handle structure for opening and closing the screen
since the screen can be moved by placing the fingers in th~ re-
cesse~ formed on either si~e.o~ the web portion 302 of the cross
section and applying pressure against either portion 29~ or 300
depending on the directior oE movement of the screen door 286
that is dssired.
The cross section of the rail mem~ers o the ~rame 2~8
further permits the use o a relativ~!ly simple loc~ing structure
320 with the screen door 286. The lo~king structure 320 in-
cludes a bushing 322, a lockin~ member 324 having eam~ing beac~
321 thereon positioned adjacen~ one end of th~ buslling 322.and
pivotally sQcured thereto by a pivot bolt 326. Ihe pivot bolt
326 extends throu~h the locXing member 324, the bushin~ 322 ~nd
the jamb 264 of the sliding door structure 262. Thus, pivoting
of the locking membsr 324 into and out of the recess provided
between the rectangular portions 298 and 300 o~ the rail cross
sections locks and unlocks the screen door 286 in a closed
position.
Spring biased adjustable rolle.r assemblies 3~5 are
provided in all four corners of the screen door structure 286
to adjust the screen door to sliding door frames which are not
exactly square. One adjusting assembly 325 is shown in detail
in Figures 22-25. The adjusting asse~bly 325 in~udes the
: biasing spring 332, an.adjustable roller assel~bly 334, and an
adjusting wedge 336.
As shown best in Figure 25, the adjustable roller
,~ :
-30-
": . , ' ` ' ' `
1~5~6~7
~ssembly 334 includes a roller hous.in~ 338 having a hook 340 at
one cnd thereof which is Eivotally engageable with a correspond-
ing hook portion 342 on a corner bracket 316 to provide pivoting
of the adjustable roller assembly 334 about the point 344 under
urging of the bias spring 332.
In the roller assembly 334 illustrated in Figure 22, a
hemispherical abutment 346 is provided on the roller housing 338
to limit pivotal movement of the roller assembly 334 out of the
recess 348 provided i~ portion 300 of the top rail 290. In the
modification of the adjustable roller assembly 334 illustrat~d in
Figure 25, the pivotal movement is limited by the abutments 350
on the sides of the roller housing 338. In either case, the
pivoting of the adjustable roller assembly 334 into the rec~ss
348 is limited by the flanges 352 on the bifurcated end of the
roller housing 338.
Openings 354 are provided in the bifurcated end 356 of
the roller housing 338 for receiving the inteyral axle portions
358 of the xoller 360 whereby the roller 360 is secu~ed in the
roller housing 338 in alignm~nt with the slot 362 therein pro-
duced by the bifurcation of the end 356 thereof. The tra~X 364
- of the frame head ex~rusion 157 is receive~ in the slot 362 of
the adjustable roller asse~blies 334 in the top rail 290 of the
screen 268, while the track 366 is received in the slot 362 in
the adjustable roller asse~blies`in the bottom rail of the
: screen 2~6.
The pivotally ad3usted position of the adjust~ble
roller assembly 334 is also limited with respect to movement
inward of the recess 348 by the adjustin~ wedge members 336
.`, ~ ` .
.
-31-
105~6~7
slid~ble alon~ ~e top and hottom rails of the scr~en 286 within
the recesses 348. As shown best in Figure 24, the adjusting
wedge me~ers 336 include the guide flanges 364 and the adjust-
ing flanges 366 by which the wcdge members are guided and moved
respectively in the recesses 348. Further, the wed~e members
336 are provided with notches 368 on inclined camming surfaces
adjaccnt the adjustable roller assemblies 334, which notches
provide points 369 for successively engagin~ a notch 370 in the
roller housing 338 of the adjustable roller asse~lies on move-
10 ment of the wedge mem2~ers 336 toward or away rom the adjustableroller assemblies.
With such spring biased adjustablc roller asse;l~lies,
the actual roller 360 may be relatively small so that the open
depth of the top and bottom rails need not be large, whereby a
relatively strong frame may be produced with a minimum of
material by a simple extrusion cross section.
In four-panel sliding door installa-tions, a portion
of one of which is illustrated in Pigure 26, an astragal adapter
373 having the general cross section illustrated in Figure 26
20 and extending substantially the full length of the locking rails
375 and 377 of the two movable door panels in such ~our-panel
door installations is secured to ona of the locking rails by-
convenient means such as scr~ws and releasably receives the lock-
ing rail of the other of the movable door panels. Conventional
handle and locking structures~may be secured to the abutting
locking rails and/or astra~al adapter.
With such structure, one of the usual sliding screen
doors 286 is provided with an L-shaped base bracket 374 secured to
--32~
105;~62~7
one of the abuttin~ locking rails 238. A bushing 37~ is posi-
tioned with one end against the bracket 374. A locking member
378 is positioned against the other end of the bushing and is
pivotally secured to the other end of the bushing by means of
the pivot bolt 380 extending through the locking member 378
the bushing 376 and the base bracket 374. The operation of
such locking structure 382 is similar to the operation of the
locking structure 320.
With the sliding door structures lO and 272, it is
often desirable to double lock the movable door panel or open
it a few inches to provide ventilation and still maintain the
movable door panel locked to prevent entry of prowlers or the
like or to prevent small children from going out of the sliding ~ ;~
door. As indicated above, in the past such locks have not been
provided on sliding door structure or have either been too
complicated or not sufficiently sophisticated. Thus~ in the
past a length of pipe which may be inserted between the frame
~amb and the free rail of the movable door panel of the sliding
door structures has been used to prevent openiong of the movable
door panel more than a predetermined amount.
In accordance with the present invention, a prowler
lock structure 384 is provided as shown in Figure 31 which in-
cludes a generally V-shaped member 386 having a notch 388 at the
end of one leg thereof~ a tamplate opening 390 adjacent the apex
thereof and an opening 392 in the apex thereof in which a stud
394 is secured extending on both sides of the member 396.
The stud 394 has enlarged headed portions 396 on the ends
thereof. The prowler lock structure 384 has the elevation
-33-
lOSZ~i27
configuration illustrated in Figure 31 and is substantially flat
except for the stud extending therethrough as shown in Figure 32.
On installation, the prowler lock member 386 is posi-
tioned with the top of one side of the movable door panel free
sicle rail received in the notch 388. The notch 388 and the
re]ative dimensions of the prowler lock member 386 together with
the positioning of the movable door side rail in relation to the
head of the sliding door frame is such that after installation,
the prowler lock member 386 cannot be removed from the moving
panel side rail without ad~usting the movable panel to its
lowermost position.
After installation of the prowler lock member 3~6 on
the side rail, the prowler lock member 386 is pivoted counter-
clockwise about the top of the side rail portion within the
notch 388 until the stud 394 on the prowler lock member 386
engages the fin of the frame head member, at which time a hole
398 is drilled through the template opening 390 in the ad~acent
fin of the head member. Such holes are drilled wherever it is
desired to lock the movable door panel.
In operation then, with the holes 398 drilled in the
head fin and with the prowler lock member 386 positioned as
indicated in Figure 31, the movable door panel may be completely
opened and closed with the prowler lock member 386 serving no
function. Nhen it is desired to lock the movable door panel in
a position at which there is a hole 398, the prowler lock member
386 is pivoted counterclockwise so that the stud 394 aligns with
the desired hole 398, after which the prowler lock member 386 is
moved transversely outwardly of the sliding door structure to

engage one end of the stud 394 in the selected hole 398. The `~
other end of the stud 394 may be used as a handle in accomp-
lishing the alignment and movement of the prowler lock member ;
386. On release of the prowler lock member 386, the head por- -
tion 396 on the end of the stud 394 within the hole 398 will
prevent accidental removal of the stud from the hole and
provide a positive lock of the sliding door panel in the -
selected position.
In the modified prowler lock structure 400 illustrated
in Figure 33, the prowler lock member 402 bas a side elevation
as shown and again is generally flat except for a stud 404
extending transversely therethrough, which stud may have a
head 406 on the side ad~acent the fin of the sliding door frame -~
head and may ha~e a nut 408 associated therewith which would
serve as a handle on the opposlte side thereof, as shown ln
Figure 34.
With the prowler lock structure 400 illustrated in
Figures 33 and 34, again the prowler lock member 402 is posi-
tioned over the end of the side rail by means of the slot 410
in which position the pro*ler lock member 402 may be moved up
or down, as desired. Again, an opening through the prowler lock
member 402 (not shown) may be used as a tamplate for drilling
holes 412 in the flange of the frame head at the locations where
locking is required.
In opera~ion, with the prowler lock member 402 in a
down position, the prowler lock structure is not operative.
When it is desired to lock the movable door panel in a selected
position~ the movable door panel is moved to the position
,

desired, thc prowler loc~ membec 402 is moved up and ~he stud
:
404 is aligned with an opening 412, a~ter wllich the prowler lock
membe:r is moved toward the fin of the fràme head to insert the
stud 404 through th^ selected hole 412 and p~ovide a positive
lock for the movabl~ door panel.
A third pro~ler lock struc-ture 414 suitable for use
with the sliding door structures 10 and 262 and illustrated in
Figure 30 includes the prowler ~ock lever 416 including the
notch 425 therein adapted to receive the upper end of the moving
panel Eree side rail. Lever 416 further has a projection ~18
on the end 420 thereof adapted to fit within openings 422 pro-
vided in the sliding door frame head. The end 424 of the prowler
lock lever 416 is weighted to bias the projection 418 into an
opening 422 in the head. A further notch 426 is provided in
lever 416 which i5 also adapted to fit over the top of the free
side rail of the sliding door moving panel and thus retain the
lever 416 in a stored position with the end 418 not biased into
engagement with the sliding door frame héad as shown in phantom
- in Figure 30.
ThuF, in operation of the prowler locX structure 41A,
~: with the top of the rail within notch 426 in lever 416, the
' .
movable door panel 16 may be moved to any desired location.
With the top of the-~free rail~of the sliding door panel in the
notch 425 in lever 416, the projection 418 of the lever 416 will
; be biased into the first opening ~22 in the frame head that it
comes to on sliding o~ the movable door panel in either direction
to positively lock and movable door panel in a desired position.
In the prowler lock structure 450 illustrated in
36-
105'~27
Figure 35, a member 452 having the elevation illustrated in
Figure 35 and a width suitable for fitting within the frame
head of the ~liding door structure over the movable door panel
is secured to the head of the frame adjacent the free end of
the movable door panel by convenient means such as screws (not
shown). A flexible spring member 456 having the configuration
shown in Figure 35 is positioned in the recess 458 and the
locking member 460 is hooked over the rib 462 by means of the
hooked end 464 thereof whereby the end 466 thereof will engage
the free side rail of the movable door panel and prevent un-
desired opening movement thereof.
When it is desired to open the movable door panel,
the lock member 460 may be pivoted clockwise by insertion of
a finger in the recess 468 after which the locked member 460
may be moved to the right in Figure 35 whereby the spring 456
maintains it in a hori~ontal position out of the way of the
movable door panel. A reverse process may be used to move the `
lock member 460 into a locking position.
If desired, the ventilation stop 474 may be secured
at the other end of the member 452 by the interlocking hook
portions 476 and 478 thereon. In operation, the ventilation
stop member 474 permits opening of the movable door panel only
a desired amountjas, for example, six inches, to prevent entry
of prowlers and undesired exit of small children, and the like.
As shown best in Figure 36, the frames 12 and 157 of
sliding door structures 10 and 262 may be secured in a building
opening 480 by means of nails passed through nailing strip
adapters 482 interlocked with a rib 485 on the frame members
-37-
lOSZ~27
where direct connection of the frame members in the building
opening is not desired. The nailing strip 482 has the cross
section illustrated in Figure 36 and may be of any desired
length. Alternate nailing strips 484 particularly suitable
for use with brick construction may have the configuration
shown in Figure 37.
Further, the interior trim of the bullding opening
; 480 may be facilitated with a trim extrusion 486 having the
cross section illustrated in Figure 36. While other building
constructions are possible, in Figure 36 brick facing 488,
interior stud 490, exterior wall 492 and interior wall 494 are
illustrated. The joint between the frame ~amb and the interior
trim extrusion 486 is closed as shown by a closure strip 494
having substantially lthe same configuration as the glazing
; member illustrated in Figure 16.
Also~ the interior trim of the building opening in
which the sliding door structure is secured may be facilitated
at the sill by means of the plastic bullnose extrusion 496
having the cross section shown in Figure 38 and adapted to fit
between the inner sill flange and the interior flooring 498.
The bullnose extrusion 496 is flexible to permit varying
dimensions of flooring to be used in con~unction with a standard
sill.
A modification of the bullnose member 496 is shown in
Figure 39 to accommodate thicker flooring such as carpeting as
may be desired or to accommodate a lower inner flange on the
frame sill. To-~this end, the extension 500 is provided on the
bullnose interior trim member 502 illustrated in Figure 39.

Furhter, the sill may be extended by means of the
adapted extrusion 504 having the cross section illustrated in
Figure 38 and shown in con~unction with wood sub-flooring and
masonry exterior building members 506 and 508.
The exterior trim member 510 illustrated in Figure 40
is unique in that it includes a relatively soft wood core 512
and an extruded shell 513 of relatively harder and/or more
weather resistant material adapted to interloc~ with the sliding
door frame as shOwn in conjunction with the frame ~amb. The
trim member 510 may be secured to the usual exterior wood building
wall by convenient means such as nails (not shown).
Interior trim may assume the configuration of extrusion
514 having the cross section shown in Figure 40 including the
pocket 516 for receiving the end 518 of the frame jamb cross
section and the flexible leg portions 520 and 522. Assembly of
the interior trim strip 514 is as shown in Figure 40.
