ARR~GEMENTS FO~ Df~Y WAI.L P~RTITIO?7S
This invention relates to door, window, and partition
arrangements for use with dry wall partitioning, and more
particularly, to framing arrangments for forming the casing
of doorways and window openings planned for dry wall parti-
tioning construction.
Modern high rise and other construction for office,
living and other facilities commonly involve a basic reinforced
concrete skeleton that provides the building superstructure
and enclosure, which leaves large open floor space of the
individual floors of the building to be subdivided, this
being conventionally done by relatively inexpensive non
floating dry wall component assemblies providing partitions
that are adapted for read~ disasse:nbli to acco~oda~e redesign
of floor layouts. My U.S. Patent 3,861,103 discloses a
floating type of partition arrangement involving dry wall
partitioning of this general type, while my U.S. Patent
3,956,851 discloses trim arrangements therefor.
Dry wall partitioning conventionally employed to
partition large open floor spaces of a building generally
comprises ceiling and floor runners in the form of metal
channels disposed in coplanar arrangem~nt between which is
assembled a panel assembly that forms the basic wall
structure involved for individual rooms, walkways and
hallways, and the like. The panel assembly involved usually
comprises a series of metal studs of the familiar channel
shaped configuration having the usual spacing (for instance,
sixteen inches on center) which have secured to same to
define either side of the wall involved, by suitable
fasteners such as screws, wallboard sheets th~t

ordinarily extend from the floor to the cei.ling. Where doorways,
window openings, or the like are to be provided for, the parti-
tioning wallboard and studding is arranged to define the opening
~involved in which is pieced together from other the materials
the casing that is to define the opening and mount the door or
window or other structure that the opening is to be equipped
with.
Heretofore the provision of the framing of the doorway,
window or the like has frequently involved expensive carpentry
work and assembly of framing components that are generally not
systemized specifically for dry wall work, and are all too
frequently supplied on a make do basis. The result frequently
is that the work product appears inconsistent in design detail-
ing, does not work satisfactorily, and provides minimal uni-
formity of appearance from one floor of the building to
ar.other. This type of installation is also complicated by
having to accommodate different door forms for closets,
pocket door arrangements, two, three and four way window
and/or door arrangements, running partitions with mullions,
and the like.
A principal object of the present invention is to
provide doorway and window opening framing arrangements for dry
wall partitions, and caps for suspended ceiling systems employ-
ing same, that are uniform and consistent i.n detailing, and
in which the casings therefore are formed from metal extrusions
that may be provided in selected standard lengths, from
which stock the casing framing components that are to form
the opening casings can be cut to size, as needed, at the
work site to accommodate frequent variations in floor/ceiling
elevations.
q The invention contemplates as a major objective that
the framing members involved for defining a doorway or window
~5/~ ~n~6~~ or
opening shall involve a~plate ~aving a web portion that is to
~25;3395
overlie the portions of the dry wall structure that define the
opening itself at one end or entrance of the opening, and
include a trim receiving socket that abuts the partition
external wall surfacing that is in marginal arrangement about
the doorway or window opening one end in question, which
socket receives in snap fit relation thereto masking trim
pieces that may be periodically replaced, which sockets also
serve as a point of securement of the casing framing to the dry
wall. The other end of the doorway or opening is similarly
equipped, with the framing plates at the respective ends of the
doorway or window involve being overlapped at the mid portion
of the doorway or window opening for joint connection to studding
of the dry wall structure masked thereby. The casing members
involved are also equipped with trim piece receiving sockets
through which the fasteners to the dry wall structure are
applied to form the indicated joint connection so that the trim
pieces will mask the fasteners when applied about the doorway
or window opening, as the case may be.
Another important object of the invention is to
provide a casing forming member for forming dry wall partition
doorways, window openings and partition caps and the like
having a basic generic arrangement which includes a web
portion of planar configuration and a trim piece mounting
socket of channel shaped configuration disposed normally of
the web portion, from which basic shaping specific casing
forming components or members for specific applications may
be provided to satisfy specific requirements for particular
types of door and window installations or the like to be
provided for.
;;33~5
Another important object of the invention is to
provide a dry wall partition doorway and window opening casing
arrangement of split, self adjusting characteristics for
accommodating tolerance variations that both masks the dry wall
and studding involved at the opening they provide, and provides
a system of mounting trim pieces of similar sizing that permits
selection from a wide variety of aesthetic effects for trim
pieces that are all mounted in a similar snap fi~ mannner for
use and changeability as desired.
Another important object of the invention is to
provide dry wall partitioning doorway and window opening casing
forming components that may be used for either door or window
installations, and in addition, the same components may be
employed in a manner for forming mullions, and arrangements
for door mounts of other than the standard hinged type, and
the like.
Still other objects of the invention are to provide
dry wall partition doorway and ~indot~ opening casing forming
arrangements that are inexpensive to manufacture, that may be
readily cut to fit as needed and assembled on the job site,
that are adapted to mount simple door and window equipment of
standard and inexpensive design, that are simply applied, that
permit standardization of appearance in a particular installation
with abundant flexibility of aesthetic variations through
standard trim piece mounti-ng arrangements, and that have long
life in use.
In accordance with the invention, assuming a doorway
or window opening defined by a dry wall partition assembly that
normally includes the usual metal studding at either side of
and across the ~op of the opening, to the sides of which wallboard
~2~3~9~
is secured to form the basic wall structure involved, the
invention contemplates that for the two vertical sides or ja~s
and head of the opening, each such part of the opening would be
equipped with a pair of casing frame members in which one of
the frame members is mounted at one end of the opening and the
other member is mounted at the other end of the opening. The
frame members each include a web portion, with the web portions
being proportioned for self adjusting overlapping relation.
The frame members are shaped to define an internal corner
portion for providing integral with the web portions a channel
shaped socket extending the length of the frame member at least
a portion of which is to overlie the margin of the partitioning
that defines the opening side to which the frame member is
applied. The respective sockets are arranged to receive in
snap fit relation thereto trim members of standard width and
shaping that have aesthetically decorated surfaces to provide
any desired aesthetic effect. One of the casing frame members
at the respective jambs and head of the opening has its web
portion equipped with a similar trim member receiving socket
for application of similar trim about the mid portion of the
doorway or window. Both the trim receiving sockets have applied
thereto the fasteners that connect same to the dry wall studding
that is adjacent thereto, so that the trim members that are to
be applied thereto will mask the fasteners as well as the dry
wall.
The basic casing frame member structural arrangements
involved may be employed to define either doorway or window
openings, and variations of the structural framing involved
accommodate the provision of special door arrangement, as for
~2.~;3395
different types of through doors, closet doors, pocket door
arranyements and the like.
Mullions, running walls, partition caps for suspended
ceiling systems, and other special structures may also be
accommodated using the basic approach of this invention.

OENER~ ~;CRIPrI~N
Reference numeral 10 of Figure 1 generally indicates a wall of the
dry wall partition type applied to floor 12 of what may be assumed to be the
floor portion of a typical building
LCM:mls 9
~i;3~S
super structure formed of reinforced concrete or other suitable
materials, of which the individual floors of the building
are to be partitioned off into rooms, hallways, etc., for
the purpose of defining office space, living quarters, etc.
The dry wall partitioning 14 comprising wall 10 in and
of itself is conventional, and as indicated in Figures 2 and 3,
the partitioning 14 typically includes wallboard sheets 16 and
18 secured to either side of upright studs 20 of the familiar
metal channel shaped type. As is the usual practice in forming
a running partition of this type, suitable runners 17, such as
those shown in my said Patents, are applied to the ceiling and
floor in vertical coplanar relation and the studs 20 are applied
between same in suitable spacing, for instance sixteen inches on
centers. The wallboard sheets 16 and 18 that form the opposite
sides of the partition 14 are secured to the opposed flanges 22
of the studs 20, as by employing suitable dry wall screws 24.
Studs 20 and runners 17 are, of course, of the familiar channel
shaped configuration, thus defining web portion 26 that joins
the flanges 22. For suspended ceiling systems, the ceiling
runners are suspended from T grids that in turn are suspended
from the building superstructure overhead floor. Floor runners
are fixed in place using suitable fasteners such as ram set
nails ~not shown).
Wallboard sheets 16 and 18, and studs and the runners
therefor 20 are arranged as needed in forming partitions 14,
both for running partition purposes, and for forming openings
that hereto form doorways, windows, or the like. In the showing
of Figure 2, the partition 14 is shaped to define doorway opening
10 .
:.a r~r~ ~ 3 3 915
30 and for this purpose two studs 20 are erected in spaced apart
relation in the manner indicated, and wallboards 16 and 18
(which are on either side of suitable floor runners 17 spaced
apart or interrupted to form opening 30) secured to their flanges
22 employing the indicated screws 24 or the like (not shown at
that portion of Figure 2 illustrating doorway 30 to avoid confusing
the drawings). Over the doorway opening 30 a horizontal frame
piece 21 of the same shape as studs 22 is suitably fixed in
place, as by being suitably anchored to the studs 20 on either
side of the doorway 30, and the wallboards 16 and 18 anchored to
its flanges 22. The wallboard sheets 16 and 18 are suitably
formed to define vertical edges 32 and horizontal edges 34 to
define the outline of the doorway opening 30. And, of course,
the doorway openings 30 may be of any proportion desired in
terms of height and width, and window or other openings may be
formed in the same manner.
The Applicant's invention is directed to providing a
simplified but effective way of completing door and window
installations on the site, and particularly with reference to
the casings that are to form the doorway and window opening and
also mask the wallboard sheeting and studding structure that
defines the basic openings involved. The Applicant's basic
approach is to provide frame members that are to form the
doorway and window casings of simplified configuration in
extruded plate form that may be supplied in standard lengths and
cut to fit to both form the doorway and window casings involved,
and mask the opening about its ends and inside surfacing with
attractive trim strips that are also to be available in standard
lengths and cut to fit as desired, and which may be pre-designed
~53395
and color coordinated as desired in accordance with a prede-termined
decorative pattern. The invention is also concerned with the
provision of dry wall partition caps for suspended ceiling
systems that have similar aspects.
The showing of Figures 1 3 is illustrative of a
standard door assembly 40 arranged in accordance with the
present invention, which comprises a split door frame or casing
42 that mounts conventional vertically hinged door 44 to swing
between the closed position shown in Figures 1 and 2, in
which it may be locked employing conventional latching
devices, and a full open position at right angles or more to the
door full line (closed) position shown in Figure 2, with the
door swung clockwise of Figure 2, to the open door position.
For purposes of description, the doorway 30 is con-
sidered to have approach ends 46 and 48 tsee Figure 2), which
are thus disposed in more or less coplanar alignment with the
respective partition sheets 16 and 18, respectively, with the
frame or casing 42 being applied about the two vertical sides or
jambs 50 and 52 and head 54 of the doorway.
The door frame or casing 42 comprises a pair o~ side
casing sections 56 and 58, and head section 60, all of which are
formed from the same materials that may be presupplied, for
instance, in extruded aluminum strips in standard len~ths, and
cut to required length as needed for accommodating the opening
for assembling purpose. The partition base trim indicated
at 61 in Figure 1 may be one of the base trim forms disclosed
in Applicant's said Patent No. 3,9S6,861.
The side sections 56 and 58 of the door frame or
casing 42 are identically arranged but reversely oriented since
they are on opposite sides of the doorway 30. Head section 54
33~
is likewise identical to the side sections 56 and ~8, but its
compo~ents are horizontally disposed as the doorway head is
involved.
The door frame or casing sections 56, 58 and 60 each
comprise a first frame member 70 applied to one.end of the
doorway 30 and a second frame member 72 applied to the other end
of the doorway. The members 70 and 72 are sub tantially identical
~ QS~n 9 ~ ~,~ ~ r ~
and each comprises the respective plates 74 and 74A ~ormed from
aluminum or the like and defining a generally flat web or base
flange 76 that has the function of masking the margin of the
doorway 30 to which the respective plates 74 and 74A are applied.
~Plates 74 and 74A each define marginal end portions 78 and 80
that extend longitudinally of and for the length of the plates
74 and 74A respectively, as does the web 76.
At the marginal edging 80, the plates 74 and 74A are
shaped to define wing flange 82 that projects from the partition
facing side 84 of same, as distinguished from the doorway
defining side 86 of same. The wing flanges 82 thus extend
laterally of the respective plates 74 and 74A and are formed
along their projecting end portions 85 with a stub flange 88
that together with the marginal edging 80 of the plate 74
defines a channel shaped trim strip receiving socket or recess
90 that provides a snap fit mounting device 92 to which trim
strip 94 is applied. For this purpose, marginal edge portion 80
of the respective plates 74 and 74A and the stub flange 88
thereof are formed with opposed rounded beads 96 that extend
longitudinally of and for the length of the respective plates 74
and 74A, and the trim pieces or strips 94 are formed with
correspondingly shaped indentations or grooves 98 for snap fit
395
application thereto to the respective sockets or recesses 90, as
will be discussed in detail later
As will be observed from the showing of Figures 2 and
3, the plates 74 and 74A are applied to the indicated ends 46
and 48 of the doorway 30 with their web portions 76 in overlapping
relation. The overlapping separate entity structural relationship
of the plates 74 and 74A thus provides a split casing arrangement
in the sense that the plates 74 and 74A are adjustable toward
and away from each other to accommodate partitions 14 of varying
thickness tolerances.
As indicated in Figures 2 and 3, the web portion 76 of
plate 74A has a section 100 offset from its other section 102,
but in parallel relation thereto, to receive the web portion 76
of the plate 74 it cooperates with, in overlapping relation
thereto. The web section 100 of plate 74A is also formed on its
door opening defining side 86 with a pair of opposed stub flanges
104 and 106 that project in parallelism centrally of the doorway
30 and that are normally disposed with respect to the web portion
76 of the plate 74A. The stub flanges 104 and 106 define trim
mounting socket or recess 108 in which trim member 110 is mounted,
with the stud flanges 104 and 106 being formed to define rounded
beads 112 and 114 that are adapted to be received in snap fit
relation with recesses 116 and 118 of trim strip 110. In the
form shown in Figures 2 and 3, the trim stripping 110 is the
same as trim member 94, the specifics of which will be described
hereinafter in connection with the showing of Figures 21 -24.
Socket or recess 108 thus forms snap fit mounting device 92A
which structurally is the same as device 92.
14.
~3395
Prior to the application of the trim members 94 and
110 to their mounted positions, the plates 74 and 74A are cut to
fit to define the door casing side frames or jambs 56 and 58 and
head 60. These components may be mitered, as indicated in
Figure 1, for close fitting rela-tion at the juncture of the door
casing jambs and head, in accordance with good workmanship
practices.
In any event, plates 74 of the casing side frames or
jambs 56 and 58 and head 60 are applied about the doorway
approach end 46, with these components being secured in place by
suitable fasteners 120 penetrating the respective wing flanges
82, the underlying wallboard 16, and the adjacent stud flanges
22.
Plates 74A are applied in a similar manner about the
margin of the doorway opening approach end 48, with similar
fasteners 120 applied to their wing flanges 82 and the adjacent
stud flanges 22 through wallboard 14 to mount these components
in place, with the web sections 100 of the plate 74A in overlying
relation to the web portion 76 of the plates 74. The overlapping
web portions of the plates 74 and 74A are then affixed to the
adjacent stud 20, and specifically its web portion 26, employing
suitable fasteners 122. Fasteners 120 and 122, which are only
diagrammatically illustrated, may be in the form of conventional
dry wall screws or pop rivets and are spaced apart longitudinally
of and applied through the respective plates 74 and 74A as
needed for secure fastening in place of these casing components.
In this respect, in the showing of Figures 2 and
3 as well as other views of the drawings, the adjacent
portions of the plates 74 and 74A as well as the adjacent
15.
~339~
portions of the wallboard sheets 16 and 18 and studs 20 are
shown in somewhat spaced apart relation for a better under-
standing of the shaping of the parts involved. In practice, the
wallboard sheets 16 and 18 abut the stud flanges they are
secured to, and the web portions 76, of plates 74 and 74A are in
abutting relation to the surfaces of the wallboard sheets 16 and
18 adjacent to same, as are the wing flanges 82. Similarly, the
fasteners 122 draw the plate web portions 76 against the stud
webs 26 in firm surface contacting relation, as will be apparent
from the nature of the structural relationships involved.
As the opening 30 is a doorway, and the door assembly
40 is of the standard hinged type, one of the plates 74 and 74A
then forming the door jambs will have applied to same a conventional
hinge 130 of the piano hinge type that conventionally comprises
leaf 132 and leaf 134 hingedly connected by pin 136. In the
arrangement shown in Figures l _3, the hinge 130 is secured to
the plate 74A at the end 48 of the doorway and on the left hand
side of Figures 1 and 2, and for this purpose, the hinge leaf
132 is suitably affixed to web portion 76 of plate 74A in any
suitable manner, as by screws, brazing, mechanical bonding, or
the like. This may be conveniently done before the plate 74A
that is to bear the hinge 130 is mounted in its operating
position.
In addition, the stub flanges 106 of the plate 74A
have their surfaces 138 that face the marginal edgings 80 of the
plate 74A covered with sound asorbent or deadening stripping
140 which may be in the form of felt or the like. The stripping
140 is conveniently secured in place by employing a suitable
bonding adhesive or the like.
16.
39S
As indicated, the plates 74 and 74A forming the door
casing head 60 are applied across the doorway opening 30 in a
similar manner, as indicated by the showing of Figure 3.
Suitable fasteners 120 are employed to affix the wing flanges 82
of plates 74 and 74A to the horizontally disposed support
member flanges 22, while suitable fasteners 122 secure the web
portions 76 of the head plates 74 and 74A to the web 26 of the
support member 21. The stud flange 106 of the head plate 74a
has sound deadening stripping 140 applied thereto in the same
manner as the corresponding stub flanges of the jamb forming
plates 74A.
Of course, the fasteners 120 and 122 are applied to
the plates 74 and 74A prior to application of the trim strips 94
and 110 to the respective plates involved, after which the
indicated trim strips may be applied to their respective trim
mounting devices 92 and 92A, which are conveniently of the same
size for interchangeability of mounting of trim strips 94 and
110 .
Door 44 is illustrated as an all wood door which has
hinge leaf 134 suitably secured thereto, as by employing screws
or the like. The door 44 includes suitable door knob 150 and
associated latching device for releasably latching the door in
its closed position shown in Figure 1, to a suitable striker
applied to the right hand plate 74A (in the showing of Figure 2)
the specifics of which may be conventional and are not illustrated
to simplify the drawings.
Referring now specifically to Figures 21 - 24, the
trim stripping illustrated in Figures 2 and 3 as trim stripping
94 and 110 is shown in greater detail together with several
~339S
alternate forms of trim stripping, as coordinated with the basic
plate arrangement involved in casing or frame plates 74 and 74A.
In the showing of Figures 21 and 23, the basic shaping
of the plates 74 and 74A is illustrated as plate segment 75,
including web portion 76, marginal edge portion 80, wing flange
82, stub flange 88, and the snap fit beads 96. As indicated in
Figures 21 and 22, the beads have an external surfacing 160 that
is essentially semicylindrical in configuration and the beads 96
extend the length of the plates 74. The plates 74 and 74A, of
course, include marginal edges 78 that are not illustrated in
Figures 21 and 22; however, it is a feature of the invention
that the web portions 76 of the plates 74 and 74A and their edge
portions 78 may be shaped in various ways to accommodate specific
needs for installation purposes. In the door casing arrangement
42, the web portions 76 of the plates 74A are offset to define
the offset sections 100 for the indicated overlapping relation
with the web portions 76 of the plates 74. However, for other
types of dry wall partition defining openings or marginal edgings,
the corresponding portions of the basic plate arrangement
represented by the plate segment 75 may be varied as needed to
serve specific ends, as will be apparent as the disclosure
proceeds.
The general nature of trim strips 94 and 110 is more
specifically brought out in Figures 23 and 24. In Figure 23 the
trim strip is designated by reference numeral 94, and it is
shown for comparison purposes in the same view with alternate
trim strips 94A and 94B. The trim strip 94 is formed from a
length of wood to define generally flat parallelipiped body 160
having a planar front face 162, planar back face 164, and side
18.
~3~3!5
edges 166 and 168 of the special configuration indicated to
provide the snap fit mounting relationships hereinbefore referred
to.
Edges 166 and 168 thus each include concave recess 170
defined by semicylindrical wall surfacing 172, diagonally
angled planar edge surfaces 174 that are angled so that their
planes converge at a point spaced from the back surface 164, and
planar edge surfaces 176 that are perpendicular to the trim
strip front surfacing 162. The surfaces 172, 174 and 176 along
either side edge 166 and 168 of the tri~ strip 94 (and trim
strip 110) extend continuously thereof, as suggested by the
showing of Figure 24.
The dimensioning of the trim stripping 94 and 110
relative to the trim strip mounting sockets 90 and 108 is such
that when a length of the trim stripping 94 or 110 is applied to
a socket or recess 90 or 108, for instance socket 90, the
diagonal edge surfaces 174 are placed in camming relation with
the respective beads 160 of the plates 74 and 74A. By pressing
inwardly of the socket 82, the corners 180 defined by the
merging of surfaces 174 and 172 are snapped past the beads 160
to seat the trim stripping 94 in the mounted position that is
indicated in Figures 2 and 3. In this connection, the proportioning
of parts is such that the beads 160 lightly grasp the surfaces
172 defining the grooves or recesses 170 to firmly hold the trim
strips 94 and 110 in mounted position. Of course, the trim
strips 94 and 110 are applied in a similar manner to either of
sockets 90 and 108, the beads 116 and 118 of which are contoured
and hold the trim strips 94 and 110 in the same manner as beads
160.

In this connection, as indicated in Figures 2 and 3,
in the applied position of the trim strips 94 and 110, the outer
edges 182 of the trim strips overlie and thus mask the trim
strip receiving socket beads 96, 116 and 118, it being desirable
that the parts be proportioned such that the side surfaces 176
are aligned with the corresponding surfaces 86 and 87 of the
plates 74 and 74A, and the outer side surfaces 117 and 138 of
stub flanges 104 and 106.
It is also pointed out that the spacing between the
bead surfaces 160 and the stripping surfaces 172 that is shown
in Figures 2 and 3 and subsequent views is solely to better
emphasize the shape of the parts involved; in practice, bead
surfaces 160 are in abutting relation with the trim groove
surfaces 172.
. The trim strip embodiment 94A comprises a one piece
plate 190 formed from aluminum or the like by a suitable extrusion
procedure and defines planar plate portion 192 having planar
facing surface 194, and stub flanges 196 along either side edge
of same that are provided with the respective beads 200 that
have a shaping comparable to beads 96 of plates 7~ and 74A and
thus define semicylindrical bead surfaces 202. The stub flanges
196 and their respective beads 200 are proportioned so that trim
strip 94A may be snap fit mounted in sockets 90 and 108 by snap
fitting beads 200 of the strips 94A past beads 96 of plate
members 74 and 7-4A, or beads 116 and 118 of the blade sockets
108, which disposes thç trim strips 94A in mounted position
wherein they are disposed in a manner similar to th~ showing of
strips 94 in Figures 2 and 3.

~53~95
The trim strip 94B is the same as trim strip 94A
except for appearance purposes it has a layer 204 of a suitable
plastic laminated on surface 194 in any suitable manner. The
plastic layer 204 may be colored as desired for aesthetic
purposes. It will be apparent that instead of a plastic layer
being applied to the plate 190, piled fabrics or the like may
also be laminated to achieve desired aesthetic effects.
In the embodiment 40A of Figure 20, the door casing 42
is the same as casing 42 of the embodiment of Figures 1 - 3. In
the embodiment of Figure 20, a second door 44 is applied on the
end 46 of the doorway 30 having the same parts and components as
the door 44 of Figure 2, as indicated by corresponding reference
numerals to the extent that the doors 44 are illustrated in
Figure 20~ Thus, the hinge 130 of the second door 44 has its
leaf 132 suitably affixed to the plate 74, and specifically its
web portion 76 at edge portion 80. The embodiment of Figure 20
is otherwise the same as the embodiment of Figures 1- 3.
VARIENT EMBODIMENTS OF THE INVENTION
Figures 4 - 19 illustrate different applications of
the basic split casing or frame arrangement of this invention

suitable fasteners similar to those illustrated in Figure 2.
The casing 42A comprises side frame or jamb sections
56A applied to either side of the doorway 30A and head section
60A applied to the head of the doorway 30A.
The jamb and head sections 56A and 60A, respectively,
each comprise a plate 74B that has the same basic components
that plates 74 and 74A, and plate segment 75, have as indicated
by corresponding reference numerals. Thus, plate 74B has web
portion 76, marginal edge portion 78B in modified form, marginal
edge portion 80, wing flange 82, its stub flange 88, trim strip
socket 82 and trim strip 94.
In the embodiment of Figures 4 and 5, the marginal
edging 76B of the plate 74A is in the form of planar stub
flanqe 230 to which sound absorbing stripping 140 is applied in
the same manner as in connection with plates 74A. Hinge 130 is
3395

thereto.
The plates 74C are applied to the partitioning in a
manner similar to plates 74A, employing suitable fasteners 122
to secure them to the adjacent studs 20, as indicated in Figures
6A and 6B. The plates 74C define a pair of sockets or recesses
256 and 258, which, for the plate 74C on one side of the doorway
30A, serve to mount trim member 94 in the same manner as socket
108, and serve as a stop for the back or rear end 260 of one of
the doors 44, while on the other side of the casing the sockets
256 and 258 serve the reverse purpose (compare Figures 6A and
6B).
The head section 240 of the door embodiment 40B
comprise a planar plate 264 suitably fixed to the supporting
channel shaped cross support 266 through the underlying wallboard
sheeting 268, as by employing suitable fasteners (not shown),
which plate 264 is integral with cross flange 270 shaped to
define a snap in socket arrangement 92 for applying trim 94 or
its equivalent thereto. Anchor plate 272, formed to define
tracks 274 and 278 is suitably affixed to support member 266,
with the doors 242 and 244 being provided with suitable roller
devices 280 and 282 that ride on the respective tracks 274 and
278 in a manner usual and customary for bypass sliding
doors. Cross bar 282 serves as a spacer between track 274
and cross flange 278, and is secured in place in any suitable
manner.
In the embodiment of Figures 8 and 9, partition 14
forms the doorway 30 to which is applied door casing 42D comprising

Referring now to Figures 25 and 26, these figures
illustrate a partition cap assembly 460 for suspended ceiling
systems in connection with which dry wall partitioning 14 is
employed, which assembly employs a number of the improvements
hereinbefore described.
The assembly 4~0 is associated with suspenâed ceiling
system 462 which in and of itself is conventional and comprises
a plurality of frame members 464 having the familiar "T"
transverse cross-sectional configuration arranged in the usual
grid form on, for instance, two foot or four foot centers, with
each member 464 being suspended from the overhead floor structure
of the basic building superstructure involved, by the familiar
suspension wires 466 suitably anchored to the members 464 in a
conventional manner, as where indicated at 468 in Figure 26.
The members 46~ comprise the familiar main flange or web 470
that is integral with cross flange 472 that is horizontally
disposed in the suspended, inverted T, position of the respective
members 464, and on which the respective conventional lay-in
ceiling tiles 474 are lai~ to form the suspended ceiling 476.
The partition cap 462 comprises a split frame or
casing 42M in the form of a first frame member 70M and a second
frame member 72M that are generally similar and are suitably
formed from aluminum or the like to include integral with the
respective members 70M and 7~ the respective plates 74 and 74A
that have shapings that are generally similar to those of door
frame or casing sections 56 and 58, as indicated by correspondins
reference numerals. Thus, the plate portions 74 and 74A of the
frame member 7~ and 72M include the generally flat base flanges
76, their marginal end portions 78 and 80, the ~ing flanges 82
30.
3395
and stub flanges 88 that define the respective sockets or recesses
90 that form the respective snap fit mounting devices 92 to
which trim strips of the type herein disclosed, such as trim
strips 94, are applied, using the rounded bead 96 and indentation
98 snap fit arrangement that has been heretofore described in
detail.
The frame member 70M has integral with its web portion
76 the upstanding flange 480 that at its upper end is angled
over at right angles thereto to form suspension flange 482 that
is to be applied to one side of the T grid member 464 cross
flange 472. Frame member 72M is formed with a similar upstanding
~lange 484 and corresponding mounting flange 486 for application
to the other side of the T frame member cross flange 472.
In addition, frame member 70M along its upper marginal
edge is formed to define a pair of spaced apart parallel side
flanges 490 and 492, the upper of which is shaped to define a
bead 96 that is to cooperate in snap fitting relation to a bead
96 formed at the marginal edge of a side flange 493 that is
integral with the main flange 484 of frame member 72M. The
lower flange 492 of member i5 a guide flange t~at is shaped
along its projecting edge 496 to guide the entry of the bead 96
of member 72M ~lange 493 behind the bead 96 of member 70M flange
490 when these components are assembled as indicated in Figure
26, whereby they form a first snap acting latch device 500 for
securing the frame members 70M and 72~ in the asse~bled casing
forming relation indicated in Figure 26. Side flange 493 in the
form shown includes vertical stop flange 495.
A second snap action latching device 502 is provided
by the members 70~ and 72M comprising a cross flange 504 disposed
33~
adjacent the base of upstanding flange 480 and extending in
parallelism to the plate 74 of member 70M and having along its
marginal edge a latching bead 96 that cooperates with a corres-
ponding latching bead 96 that is formed at the marginal edging
78 of the plate 74A (of member 72M).
The conventional ceiling runner 17A is affixed to the
members 70M and 72~ by the aforereferred to suita~le fasteners
122 which also secure the plate 74 and 74A together. Plates 74
and 74A may be formed with the respective indexing flanges 506
and 508 between which the runner 17A is received (the runner 17A
being of the usual channel shaped configuration).
In assembling the cap assembly 460, after the suspended
ceiling grid has been applied in place in the usual manner to
provide the indicated griding of the T shaped grid members 464,
the undersides of the cross flanges 472 of the grid members 464
that are to support partition caps of the type illustrated in
Figure 26 are suitably marked (as by using chalk or paint) to
indicate the location of the caps 460, and then the caps 460 for
particular lengths of partitioning 14 are then assembled in the
manner indicated in Figure 6, prior to the erection of the
partitioning 14 involved. For this purpose, the members 70M and
72M that are to form a particular cap 464 for particular lengths
of partitioning 14 are selected and cut to the needed lengths,
and then are assembled together with the runner 17A that is
to be carried by same, and are applied to the grid member 464
they are to be associated with, in the manner indicated in
Figure 26, with the strips 94 being initially left off the
respective sockets or recesses 90 thereof. This, of course,
involves bringing the respective members 7OM and 72M up to
the level of the grid member 464 in question and bringing
~3~5
them together on either side of the grid member flange 472
in enclosing relation thereto (as indicated in Figure 26),
with flange 472 under the respective suspension flanges 482
and 486, so that snap acting latch devices 500 and 502 of
members 70M and 72M are ~rought into latching relation,
and resting the assembled memhers 70M and 72M on the grid
member 4~4. The runner 17A i5 then secured in place with
the suitable fasteners 122.
The partition 14 may then be erected in the usual
manner below the cap 460, with the wallboard sheets 16 and 18
and studs 20 being fitted between the respective wing flanges 82
and the runner side flanges 22 that are on either side of the
cap 460 as the erection proceeds. After the suitable fasteners
24 have been applied between the wing flanges 82 and the studding,
through the respective sheets 16 and 18, on either side of the
partition 14, the assembly of the particular cap 460 is completed
by applying the decorative strips 94 to the respective sockets
90 .
Referring now to Figure 27, which is a view comparable
to that of ~igure 26, but illustrates a modified partition cap
460A arranged for incorporation in door casing 42 of the double
door assembly 40A of Figure 20, in place of head section 60
tthat is shown in Figure 3). The arrangement of Figure 27
contemplates that the side casing sections 56 and 58 of the door
casing 42 in question will be of such height relative to the
suspended ceiling system 476 such that partition cap 460A will
fill the gap between the upper ends of the doors and the ceiling
tiles 474.
33.
339~;
The cap 460A comprises split casing section 42N that
is made up of a firs~ frame member 70N and a second frame member
72N which are generally similar to the corresponding frame
members 70M and 72M of cap 460, as indicated by corresponding
reference numerals. Thus, the frame members 70N and 72N include
the respective plates 74 and 74A and their associated parts ~hat
have been hereinbefore described in detail, which are respectively
integral with the respective upstanding vertical flanges 480 and
484 that are shaped in the same manner as shown in Figure 26,
and as indicated by corresponding reference numerals. Thus, the
frame members 70N and 72N are secured together by the respective
snap lock devices 500 and 502.
In the cap arrangement 460A, the plates 74 and 74A do
not have the indexing flanges 506 and 508, and the channel
shaped plate 350 described in connection with the embodiment of
Figure 12 is received between the wing flanges 82 of the respective
plates 74 and 74A, with its web portion 352 substantially
aligned with stub flanges 88 of plates 7~ and 74A. The plate
350 includes the aforedescribed stub flanges 360 an~ 362 that
provide for snap fit application to the soc~et 90 defined thereby
of trim strip 94.
The partition cap 460A is assembled prior to assembly
of the door arrangement 4 OA . The location of the door 4OA
having been predetermined prior to construction of the partitioning
14 that will be involved in the room space being subdivided, its
location may be conveniently marked or laid out on the undersurface
of the cross flange 472 of the grid member 464 involved (as by
using chalk, paint, etc.). A pair of the frame members 70N and
72N may then be selected, appropriately cut to length, and
34.
33g5
assembled together in the manner indicated in Figure 27 on the
floor of the room space being assembled, with the strips 94
thereof left off. The channel shaped plate 350 may then be
applied thereto with the positioning indicated in Figure 27, and
secured between the respective stub flanges 82 by the connectin~
devices 122. Prior to this, the plate 74 and 74A may be secured
togethex by a suitable fastener 122.
The strips 94 then may be applied to the respective
~ockets 90 defined by the cap 460A, and the cap 460A applied to
its supporting grid member 464 in the manner already indicated
with regard to the embodiment of Figure 26~
The remainder of the door assembly 40A may then be
completed in accordance with the disclosure of this application,
following the general arrangement shown in Figures 1 - 3 and 20.
The strips 9~ and the components defining the respective sockets
90 of the plates 74 and 74A may be appropriately shaped to
provide the mitered door frame configuration shown at the top of
the door frame shown in Figure 1, as will be obvious to those
s~illed in the art.
In the arrangement of Figure 28, the partition cap
460A is employed as a cap for window installations of the type
shown in Figures 13 - 18. For descriptive purposes, Figure 28
may be considered to be a vertical sectional view taken substantiall~
along line 28--28 of Figure 13, with the window installation 374
there involved thus including the pane 370, the plates 74 and
74A that are on either vertical side of the window as indicated
in connection with the disclosure of Figure 13, the trim members
110 that are supported by the respective plates 74A in the
manner indicated in Figure 13, and the wooden trim members 376
3 3 9 ~
that are suitably mounted about the margin of the casing 42G of
which the cap 46OA forms a part.
Figure 28 also illustrates the basic plates 74 and
74A, arranged as indicated in Figures 1 - 3, employed to form
the foot section 510 o~ the window installation 374. The frame
members 74 and 74A are arranged in the manner indicated in
Figures 7 - 3, as indicated by corresponding reference numerals,
with the respective webs 76 supported on the spaced apart two by
four beams 512 and 514 and having their respective wing flanges
82 secured to the respective beams 512 and 514 by the respective
fasteners 120. The beams 512 and 514 may be anchored to the
basic floor structure 516 in any suitable manner if so desired.
Suitable conduiting 518 may be disposed between the beams 512
and 514 if desired for a particular installation. The sockets
or recesses 90 of the plate 74 and 74A involved in the base
section 510 are equipped with the strips 94 in the manner hereinbefo
disclosed.
As is also indicated in Figure 28, the trim strips llQ
are applied to the sockets or recesses 108 in snap fitting
relation thereto in the manner described in connection with the
disclosure of Figures 1 - 3.
The application of the cap 460A for the window instal-
lation 374 is performed in the same manner as in connection with
the embodiment of Figure 27. Thus, the underside of the cross
flanges 472 of the grid frame members 464 is marked at the
location of the window installation 374, and the cap 460A
applied to such member 464 in the manner described with reference
to Figure 27. The casing 42G may then be completed with the cap
460A serving as the head section of same with the side frames of
36.
~33g5
the window installation 374 being defined by employing plates 74
and 74A arranged as indicated in Figure 13 at either side of the
window installation. The indicated window side frames and head
section as defined by the cap 460A are suitably shaped for
mitering in the manner suggested by the showing of the door
arrangement of Figure 1.
Prior to t~e application of pane 370 to the window
installation, the base section 510 is completed, and after the
pane 370 is applied as indicated, trim 376 is suitably applied
ahout the margin of the pane, as by having the trim pieces 376
suitably secured to the plates 74A, or the plates 74, as the
case may be, as by employing suitable fasteners such as screws
or the like.
It will thus be apparent from the disclosure of Figures
25 - 28 that where the cap arrangements of these Figures are
employed throughout a particular floor space between floors of
a building superstructure to be subdivided, the entire partitioning
subdivisions may be laid out on the grid 362, prior to the ap-
plication thereto of the ceiling tiles 374~ ~hus, the caps 460A
that are to be applied over door and window installations may be
positionally and dimensionally located on the undersides of
cross flanges 472 of the grid support members 464 involved ~in
accordance with a predetermined floor plan), and the remaining
lengths of the grid members 464 may be assumed to support a cap
460 for partitioning 14, if that type of layout be suitable for
the particular partitioning arrangement to be provided. The
caps 460 and 460A may then be assembled and mounted in place
about the entire space being subdivided, after which the partitionin
~33~S
14, the door assemblies, and the window installations may be
installed from the floor surface up to th~ caps. Of course, it
is desirable that the caps employed as represented by the caps
460 and 460A have comparable dimensioning horizontally and
vertically so that they match about the perimeters of the resulting
room space provided by the partition subdivisions.
It will also be apparent that the caps ~60 and 460A
may be applied with appropriate modifications to the other
partitioning illustrations disclosed in this application, with
such modifications being made as will be found to be necessary
by those skilled in the art.
It will therefore be seen that the inve~tion provides
a casing arrangement for forming doorways and window openings
which has a variety of uses and applications in addition to
being employed for their primary purposes of defining and
masking doorways and window openings. Involved is a basic
framing component and trim strip therefor, the generic specifics
of which are shown in Figures 21 - 24. This basic component may
be modified for use at one approach end of a doorway for special
installations such as in the embodiments of Figures 4 - 8, but
the general purpose use provided by the split frame or casing
arrangements illustrated in Figures 1 and 2 and 12 - 19 provides
significant flexibility in working with wallboard partitioning
and door and window installations to be associated therewith.
The invéntion also provides partition caps for suspended ceiling
systems, and similar caps for door and window structures of the
type disclosed, which caps ha-~e the basic split casing approach
and the framing components and trim strips therefor that are
involved in the doorway and window opening casings. The plates
38.
~33~
that form the various casing sections may be and preferably are
in the form of economical aluminum extrusions of standard lengths
that may be cut to size at the job site as the partitioning and
its doors and windows etc. are being installed. The trim stripping
arrangement provided in association with same also permits the
trim stripping to be of varient aesthetic effects provided in
standard lengths that also may be cut to size and snap fitted
into place as the installations involved are being completed.
The decorative facings presented by the trim strips may be color
coordinated or otherwise have their appearances planned in
advance so that the decorative effect for any floor of the
building to be subdivided as described may be the same or in any
predetermined relationship that may be desired.
The securement of the casing frame sections to the
partitioning and other components is ~y way of simple fasteners
of any conventional type suitable for the purpose, and in the
split framing casing embodiments of the invention, the framing
adjusts widthwise to accommodate, for instance, tolerance
variations in partition widths, automatically as phrt of ~eing
secured in place.
The various ~orms of trim stripping or pieces illus-
trated are interchangeable and the trim stripping that may be
applied to the snap fit sockets about the margins of the doorway
and window frames and/or along the partition caps, may also be
applied to the trim strip socketing within the openings thereby
provided, and vice versa.
The foregoing description and the drawings are given
merely to explain and illustra-te the invention and the invention
is not to be limited thereto, except insofar as the appended
39.

claims are so limited, since those skilled in the art who have
the disclosure before them will be able to make modifications
and variations therein without departing from the scope of the
invention.
