MOLDING CLIP
This invention relates to a clip for l~obilizing a
decorative molding to be attached along the edge of the plate
of glass in the front or rear window of an automobile.
In setting a plate of glass in the front or rear window
of an automobile, it is a widely known practice to fasten a
molding along the edge of the window for the purpose of filing
up the gap occurring between the edge of the window frame and
that of the plate of glass or imparting a decorative effect to
the bondary.
The fastening of the molding has heretofore been accom-
plished generally by a method which comprises embedding T-
shaped studs at suitable intervals along the edge of the
window, fastening the plate of glass to the edge by use of an
adhesive agent, attaching a clip made of synthetic resin to
each of said studs and bringing the molding into fast engage-
ment with the clips. Another method heretofore used for this
purpose comprises causing clips made of resilient metal plate
material to be attached in advance to the edge of the plate
of glass, setting the plate of glass in position in the window
opening so as cause the plate of glass to be immovably joined
to the edge of the window in conjunction with said clips by
the medium of an adhesive agent applied in advance to said
edge of the window and thereafter bringing a molding into fast
engagement with the clips.
The former method necessitates preparatory individual
welding of the T-shaped studs adapted to permit attachment of
clips and furthermore involves the subsequent extra work of
attaching the clips to the welded studs and, hence, the operation
',~

1065~Z4
as a whole proves to be inefficient and costly. The latter
method immobilizes the clips not by relying upon studs pre-
paratorily imbedded into the window frame but by utilizing
an adhesive agent primarily intended for fastening the plate
of glass to the window frame. Use of this method, therefore,
advanced training in the work of applying the adhesive agent
and the work of setting the plate of glass having clips
attached thereto in position in the window frame and is
hardly appropriate for adoption in an assembly line. Because
of the use of clips made of a metal, this method has an
additional disadvantage that the clips tend to rust and, at
the time of assembly, are likely to cause scratches in the
paint finish of the automobile.
An object of the present invention is to provide a
molding clip which is outstandingly adaptable to use in mass
production assembly in that it is not likely to mar the paint
finish of the window frame, in that it is totally safe from
rusting, in that it permits easy selection of the position
for its attachment and in that it can be attached simulta-
neously with the plate of glass to the window frame;.
Another object of the present invention is to provide amolding clip which insures easy attachment of the molding,
precludes the possibility of the clip being pushed out of
- position by the attachment of the molding and permits later
release of the molding from engagement with the clip if such
should become necessary.
Still another object of this invention is to provide a
molding clip which can be integrally molded easily and in-
expensively by the techni~ue of injection molding of a plastic

~06S9Z4
material and which can easily be adapted to the existing process
of molding attachment.
The invention in its broader claimed aspect comprehends
a one-piece plastic molding clip which includes a generally
planar base plate adapted to be attached on its back side by
adhesive means to a window opening flange in an automobile. At
least one engaging arm is attached at one end to a lower edge of
the base plate and extends substantially parallel to and in spaced
relation to the plane of a central portion of the base plate,
the at least one engaging arm being provided at the free end
thereof with a molding engaglng snap catch. At least one
resilient receiving member is disposed in spaced relation to a
front side of the base plate and connecting means permit it
to extend from adjacent an upper edge of the base plate opposite
the lower edge downwardly in spaced relation to the front side
of the base plate in the direction of the lower edge and is
adapted to resiliently receive an edge of a plate of glass.
With this molding clip, required attachment of a decorative
and plate glass-immobilizing molding possessed of a flap portion
is accomplished by joining the rear surface of said base plate
through the medium of a two-face adhesive tape to the edge of the
window frame, allowing the edge of the plate of glass to be set
in the window frame to be supported by said resilient receiving
members, setting the plate of glass in position in the window
frame and thereafter bringing the molding into hooked engagement
with a molding-engaging piece. This molding clip enables the
plate of glass to be easily and safely attached immovably to
the window frame by causing the plate of glass to be supported
on one side of the edge thereof by the clip fastened to the window
frame and on the other side of the edge thereof by the molding
fastened to the molding-engaging nail catch. Since the clip is
fastened to the window frame by means of an adhesive tape, the
- positioning of the clip can easily be attained without inflicting
injuries to the paint finish of the window frame. Release of
B the clip from
--4--

~0659Z4
engagement with the molding can be carried out easily if it
should become necessary to replace the plate of glass.
Because of the simplicity of its structure, the molding
clip of the present invention can easily be integrally molded
by the conventional technique of injection molding of a
plastic material and can readily be adapted to the existing
process for the engagement of the plate of glass and the
molding.
The other objects and characteristic features of this
invention will become apparent from the detailed description
to be given hereinbelow with reference to the accompanying
drawings.

conventional molding clips.

of other preferred embodiments of the molding clip according

Figure 11 is an explanatory diagram relating to the
possible accidental release of the engagement of the molding
clip according to this invention.
Figure 12 through Figure 15, incl. are explanatory
diagrams illustrating still other preferred embodiments of
the molding clip of the present invention.
Figure 1 illustrates a typical example of the conventio-
nal molding clip, representing a partially enlarged view of awindow frame F used in an automobile for attachment of a
wind-shield or a rear window.
A plate of glass G for the window is immobilized by
being supported on one side by a molding M held in position
by a molding clip 1 and on the other side by the edge portion
of the window frame F through the medium of a packing material
such as an adhesive agent.
With the conventional molding clips of such a construc-
tion, studs S must be fixed by welding or some other means at
prescribed positions along the window frame to permit fasten-
ing of the clips to the window frame F.
The conventional molding clips are each provided at the
lower central portion with an Q-shaped fitting hole 2 for
receiving the head of a stud S and at the upper portion with
a molding engaging nail catch 3 for permitting hooked engage-
ment of the hooked portion of the molding.
With these conventional molding clips, required setting
of the plate of glass is accomplished by fastening said
molding clips to the window frame F while allowing the head

10~59Z4
portions of studs S to be inserted into the fitting holes 2,
applying a packing material such as adhesive agent to the end
portion of the window frame F, thereafter inserting the plate
of glass in position into the window frame and, after the
plate of glass has been get in position as described above,
forcing a springy metallic molding between the window frame F
and the molding clip with the hooked portion at the leading
end and bringing the hooked portion into hooked engagement
~ with the molding engaging nail catch so as to obstruct re-
lease of the molding.
Since the conventional molding clips necessitate pre-
paratory embedding of studs as described above, the fabrication
of the window frame inevitably entails the extra work of
complicated welding and the insertion of the molding may
scratch paint finish of the window frame. Removal of the plate
of glass fastened in position or the molding held in hooked
engagement may be accomplished by breaking the molding or
molding clips or by strongly pushing up the plate of glass from
below (in the position of the drawing) with force enough to
upset the inserted engagement between the studs S and the
fitting holes 2 of the molding clips. In either case, the
removal is not obtained readily.
The conventional molding clips of the construction of
Figure 1 have a serious disadvantage in terms of both ease of
handling and cost.
Conventional molding clips of another structure illust-
rated in Figure 2 are formed each by fabricating one metal
sheet in the shape o~ the letter U as shown in Figure 2(B).
As many molding clips 4 as necessary are clamped astraddle

1065924
the edge portion of the plate of glass G in advance. To the
peripheral edge of the window frame F, a packing material P
of adhesive agent or the like is applied in advance. As the
plate of glass is fastened to the window frame F, the tongues
5 of the molding clips are allowed to be embedded into the
packing material P. When the plate of glass is set in posi-
tion onto the window frame F by means of the adhesive packing
material P, it is ready for attachment of a molding M to the
periphery thereof. This attachment of the molding is accom-
plished by bringing one of the bent portions formed at theopposite ends of the molding into hooked engagement with the
engaging member 6 formed by cutting and raising a portion of
the molding clip in the shape of an S and bringing the other
bent portion into hooked engagement with the engaging member
7 formed by bending the end portion of the molding clip. As
the plate of glass G is held fast in position by the molding
clips, it is resiliently held at its end portion by glass
receiving pieces 8, 8.
With the conventional molding clips,of the foregoing
construction, the setting of the plate of glass and the molding
is effected by a method which comprises fastening the clips
preparatorily to the edge of the plate of glass and fastening
the plate of glass in conjunction with the molding clips onto
the edge of the window frame by use of an adhesive agent
applied in advance to said edge. Unexpectedly, this applica-
tion of the adhesive agent requires an adva~ced technical
skill on the part of the worker. In fact, the required degree
of skill is so great that the method as a whole is hardly
usable in an assembly line, thus depriving the method of its

1065924
technical feasibility.
The conventional molding clips of the construction under
discussion are produced by fabricating resilient metal sheet
to shape. They, therefore, have a disadvantage that the clips
eventually rust and thiS rust transfers to the automobile body
and the plate of glass surface. The clips are also likely to
scratch the paint finish of the automobile body if they should
accidentally collide with the painted surface during the work
of window assembly. Such scratches can eventually cause
corrosion of the substratal metal through the marred surface.
Besides, possible variation in the size of the plates of glass
and variation in window size cause a variation in the retain-
ing strength of clips and, on account of close association
with the rigidity of the molding in use, a gap is likely to
occur between the automobile body and the molding, with the
undesirably result that the molding suffers from impaired
appearance and degraded quality.
In view of the various disadvantages suffered by the
typical molding clips heretofore available as described above,
the present invention aims to provide molding clips free from
these disadvantage. Now, the present invention will be
described with reference to the preferred embodiments illust-
rated in Figure 3 and the subsequent figures.
A clip 11 is formed having as its main component parts
a base plate 12 adapted to be laid in face-to-face contact on
the wall rising from the window frame F, a springy engaging
piece 13 vertically rising from the lower edge of said base
; plate and provided at the free end thereof with a backwardly
projecting nail catch 15 for hooked engagement with the molding

~6592~
and resilient receiving members 14, 14 protruding from the
upper edge of the base plate to the front side of the base
plate (Figures 3 and 4~. Said base plate 12 functions as a
base seat immobilized to the edge of a window frame and is
provided with a base piece 16 protruding from the lower edge
thereof perpendicularly to the front side. The clip is
brought into stable engagement for snug rest at the corner
portion of the edge of the window by causing the rear side
of the base plate and the lower side of the base piece 16 to
come into perfect contact with the two inner sides of the
corner portion.
The engaging piece 13 serves to retain the molding in
hooked engagement by bringing the hooked edge of the molding
M into engagement with the molding-engaging nail catch 15
formed at the free end thereof. In the illustrated embodi-
ment, this engaging piece 13 is formed in a rising state as
if cut off and raised from the central portion of the base
plate 12. The main body of the engaging piece 13 is so
formed as to stand substantially past the front face of the
base plate and the molding-engaging nail catch formed at the
free end of said engaging piece is extended so much that the
leading end thereof protrudes beyond the rear face of the
base plate. The rear side of the engagillg piece 13 immedi-
ately below the molding-engaging nail catch 15 is notched to
form an indentation 17 and the opposite side of the engaging
piece 13 from said indentation is extended to give rise to
an ear piece 18 adapted to permit hooked engagement of a tool
which is used for releasing the molding from its engagement
with the nail catch. The resilient receiving members 14, 14
-- 10 --
.,

10659Z4
serve the dual purpose of receiving the edge of plate of glass
G being set in the window frame and, by virtue of the pressure
generated by said reception of the plate of glass, pressing
said base plate against the edge of the window frame. In the
preferred embodiment under discussion, they are extended from
the upper edge of the base plate in a down-folded state and
the extended portions are downwardly inclined toward the front
so as to thrust out of the front side of the base plate, with
their leading ends sharply bent up to form receiving portions
19, 19. In the preferred embodiment illustrated here, the
resilient receiving members are disposed one on each side of
said engaging piece 13 in a symmetrical relationship relative
to said engaging piece 13. Owing to the overall arm length
including the folded portion, these receiving members manifest
resilience, so that the edge of the plate of glass may be
snugly received by the receiving portions 19, 19 formed at the
forward ends thereof. The front sides of said resilient
receiving members are twisted sideways so that the inner edges
of the front sides protrude in the form of ridges. When the
plate of glass G is set in position as described afterward,
these protruding ridges serve the purpose of preventing the
edge of the plate of glass from scraping off the adhesive
packing material P applied to the lower face of the plate of
glass.
Thin-walled tongue pieces 20 formed on the rear side of
the base plate and extending beyond the upper edge of the base
plate are provided one on either side of the free end of the
engaging piece. When the molding M is brought into engagement
with the nail catch 15, the tongue pieces 20 are caused to
-- 11 --

i5924
come into contact with the outer side of the hooked edge of
the molding M, thus serving to prevent the molding from
coming into direct contact with the edge of the window frame.
Subsequently, in the clip of the construction described
above, a two-face adhe~ive tape 21 is attached (or an adhesive
agent may be appliedl to the rear side of the base plate 12
and the clip is pressed and fastened immovably against the
rising wall of the window frame through the medium of said
tape. In this case, the base plate is pressed against the
rising wall only after the clip has been positionally stabi-
lized by causing the base piece 16 formed at the lower edge
of the base plate to fall snugly into perfect rest at the
corner of the window frame. After a plurality of clips have
been adhesively fastened at suitable intervals to the edge of
window frame as described above, the plate of glass G having
an adhesive packing material P applied in a required thickness
to the lower face of its edge is poised over the array of
clips and the edge of the plate of glass is slid on the front
sides of the resilient receiving members 14, 14 and driven
backwardly until it comes into tight contact with the receiving
portions 19, 19 at the leading ends thereof while causing the
pressure exerted by the edge of the plate of glass in motion to
spread out the excessively applied adhesive packing material.
Consequently, the adhesive packing material buries the lower
portion of the base plate 12 and the forward ends of the
resilient receiving members 14, 14 and, after it is left to
set, solidifies to immobilize them collectively. In this case,
the possibility of the adhesive packing material P applied to
the edge of the plate of glass being spread out under said

10659Z4
pressure toward the interior portion of the plate of glass
may effectively be precluded by providing the lower surface
of the plate of glass with a rubber seal 22 in advance.
After the clips have been fastened to the window frame
F in consequence of the adhesion of the edge of the glass of
plate, the molding M is brought down to cover the clips and
the hooked edge at one end of the molding is wedged in between
the tongue pieces 20, 20 and the leading ends of engaging
pieces 13 (Figure 4~, with the result that the wedging makes
the molding-engaging pieces 15 bend forward and causes the
hooked portion thereof to be brought into hooked engagement
with the molding-engaging nail catch. The attachment of the
molding is thus brought to completion (Figure 5). In this
case, the molding M is pressed down in the direction of ex-
panding the hooked edges at the opposite ends thereof so asto generate a repulsive force in the molding itself. After
the molding is fastened to said molding-engaging nail catch
15, said repulsive force presses the remaining free folded
edge against the front surface of plate of glass and prevents
any gap from occurring between the plate of glass and the
molding.
Since the molding is fastened in position as described
above, the clips tend to be lifted forward or upward by the
repulsive force of the molding and consequently pull in the
pealing direction the base plate 12 which has already been
immovably fastened to the edge of window frame through the
medium of sald adhesive tape. Nevertheless, the attachment
of the molding does not cause the clips to be pushed up and
the prying force exerted by the molding upon the engaging
- 13 -

1~659Z4
piece does not peel the adhesive tape because the engaging
piece serving to keep the molding directly in hooked engage-
ment is connected to the lower edge of the base plate and
consequently transmits the resilient force of the molding
indirectly to the base plate as previously described, because
said resilient receiving members 14, 14 support the edge of
the plate of glass and, under the load of the plate of glass,
press said base plate against the rising wall of the edge of
the window frame and further because the receiving portions
l9, 19 formed at the forward ends thereof are held in firm
contact with the lower side of the plate of glass to offset
the upward pull.
With the molding clips produced according to the present
invention, therefore, even when the molding is attached
before the adhesive packing material P has thoroughly solidi-
fied, the clips will not come off their attached positions
on the window frame F but will maintain the molding in hooked
engagement therewith. Thus, the attachment of the molding
can be started before the adhesive packing material has been
completely solidified. This means that the work of molding
attachment can be carried out very ~uickly. And the molding
thus atta'ched in position to the window frame will not suffer
from such undesirable phenomena as partial peeling but will
insure safe fastening of the plate of glass.
The receiving portions 19, 19 of the resilient receiving
members are held in fast contact with the lower side of the
plate of glass and prevent the clips from lifting up. In the
present preferred embodiment, they intervene between the
glass and the window frame F and give rise to a fixed gap for
- 14 -

10659Z4
retaining the adhesive packing material therebetween. Because
of this fixed gap, a required amount of adhesive packing
material remains intact in the gap in spite of the pressure
which is produced when the plate of glass is mechanically
inserted in position.' The adhesive packing material thus
retained in the gap serves to effect adhesive attachment of
the plate of glass and seals airtightly the gap between the
plate of glass and the edge of the window frame.
Figure 7(A) and Figure 7(B) represent another preferred
embodiment involving a partial modification with respect to
the resilient receiving members 14, 14 and the base piece 16
of the preferred embodiment described above. This modification
resides in omitting the formation of the receiving portions
at the forward ends of said resilient receiving members and
instead enlarging the base piece 16 for thereb,v forming on the
upper side thereof a pillow 23 for supporting the lowe,r side
of the plate of glass.
In this preferred embodiment, the base piece serves to
stabilize the attachment of the base plate 12 as described
previously and the pillow 23 formed on the upper side thereof
supports the lower side of the plate of glass and prevents the
plate of glass from sinking further down and insures undis-
turbed retention of the adhesive packing material. At the
same time the base piece becomes buried itself under the pool
of adhesive packing material and consequently immobilizes the
clip as a whole. When the molding is attached to the clip,
the base piece which is held in tight contact with the lower
side of plate of glass prev'ents the clip from lifting up and
also serves the purpose of preventing the adhesive tape from

~065929~
peeling off. The preceding preferred embodiment requires
the adhesive tape to be applied to the rear side of the base
plate. Owing to the enlargement of the area of the base
piece, the present preferred embodiment can immobilize the
clip by means of an adhesive tape applied to the lower side
of the base piece.
Figure 8 through Figure 10, incl. represent modifications
to the preferred embodiments described above. The preferred
embodiment of Figure 8 has engaging pieces disposed one on
either side of the base plate 12, that of Figure 9 has resili-
ent receiving members 14, 14 extending between the upper edge
of the base plate 12 and the receiving piece 16 with their
respective opposite ends integrally connected to the upper
edge of the base plate 12 and the receiving piece 16 and that
of Figure 10 has resilient receiving members 14, 14 of the
preferred embodiment of Figure 9 cut off at the upper ends
thereof from the upper edge of the base plate and supported
exclusively by the receiving piece. All these pxeferred
embodiments produce identical effects to those obtainable by
the preferred embodiments illustrated in Figure 3 through
Figure 6, Figure 7(A) and Figure 7(B).
To enhance the safety o~ the attachment of the molding
and the plate of glass, the present invention also provides
a molding clip of a construction that will now be described.
By way of example, there will first be considered a
case in which the molding clip of this invention illustrated
in Figure 3 breaks loose from engagement owing to inferior
workmanship during the attachment of the molding and the
plate of glass. This problem will be discussed with reference
- 16 -

o~
10659Z~
to Figure ll.
In the initial stage of the insertion of plate of glass,
when the edge of plate of glass comes into sliding contact
with the resilient receiving members l9 and forces the resi-
lient receiving members to bend in the direction of the frontsurface of the base plate 12, the resilient receiving members
are subject to the downward force exerted by the edge of the
plate of glass. Since this downward force functions as a
counterclockwise moment in the entire clip, the upper portion
of the base plate tends to depart from the window frame F,
the lower portion thereof tends to press the adhesive tape
toward the interior and the clip ll tends to incline down
wardly in the front direction and break loose from the window
frame. Since the work of wedging the molding in between the
engaging piece 15 and the tongue piece is carried out before
the adhesive packing material P applied to the edge of the
plate of glass has been thoroughly solidified and since the
hooked edge of the molding M repulses the engaging piece 15
toward the front side, a force is additionally exerted to
remove the clip from the aforementioned state. Consequently,
the adhesive tape is peeled off the clip's base plate or the
window frame and the clip may possibly break loose. This
trend is particularly conspicuous when the substrate of the
adhesive tape is made of a material deficient in resilience.
This is because the inclination of the base plate increases
and the distance between the upper edge of the base plate
and the edge of window frame consequently increases in propor-
tion as the amount of deformation of the adhesive tape
increases,
- 17 -

- ~06S924
For this reason, the preferred embodiments of the present
invention to be described hereinbelow each have provided at
the lower portion of the rear side of base plate with a
protrusion having a height equal to or slightly smaller than
the thickness of the tape 21 being used. When the aforemen-
tioned force develops and tends to exert its impact, said
protrusion stops itself against the edge of the window frame,
bears-the force and prevents the clip from inclining down-
wardly toward the front side and breaking loose from the
engagement.
Figure 12 illustrates a preferred embodiment in which
protrusions 24, 24 having a height slightly smaller than the
thickness of the adhesive tape 21 are formed along the lower
edge and upper edge of the rear side of the base plate 12 and
the adhesive tape 21 is applied to the rear side of the base
plate between the two protrusions. In this case, in the
initial stage of the insertion of plate of glass, namely
while the resilient receiving members 14 have not yet been
bent by the edge of the plate of glass in the direction of
the base plate 12, the force exerted by the edge o~ the plate
of glass is received by the upper edge of the base plate at
which the resilient receiving members are attached to the
base plate. As a result, the upper edge of the base plate is
moved in the direction of the window frame. The protrusion
24 formed along the upper edge serves to prevent such move-
ment of the upper edge of the base plate. The protrusion 24
formed along the upper edge, however, fails to fulfil the
purpose of bearing the force exerted during the insertion of
the molding and, for that reason, may be omitted. The protru-

sions are not always required to be formed continuously as
illustrated but may instead be formed in segments, for
example, in two segments falling one on each end or in three
segments of which two fall one on each end and the remaining
one falls at the center; Presence of the protrusion 24
prevents the adhesive tape from exposure.
If these protrusions are formed on the rear side of the
base plate in the portions which have heretofore been used
for application of the adhesive tape 21, then the area availa-
ble for application of the adhesive tape is decreased by the
area occupied by the protrusions and the strength of attach-
ment to the window frame is proportionally decreased. Such
undesirable decrease may be eliminated by increasing the area
of the base plate enough to provide the same area for appli-
cation of the adhesive tape. If the size of the window
opening in the direction of depth, namely the size of the
base plate in the vertical direction, is limited, then the
problem may be solved by forming extended portions 25 one
each at the opposite ends of the base plate as illustrated in
Figure 14 or Figure 15 and further forming protrusions 24
each at the lower ends of the rear sides of said extended
portions 25.
According to the molding clips of the present invention,
in the initial stage of the insertion of the plate of glass,
when the edge of the plate of glass pushes and bends the
resilient receiving members 14 in the direction of the front
side of the base plate, the moment exerted on the base plate
of the clip tends to cause the lower portion of the base
plate to press the adhesive tape and make the base plate
-- 19 --

incline downwardly toward the front side. However, the
protrusions 24 bear this force and keep the adhesive tape
from being pressed down, so that the base plate hardly in-
clines (Figure 13). Thus, the possibility of the base plate
breaking loose from the attachment with the edge of the
window frame is completely eliminated. Similarly, the force
which tends to pry the base plate out of the window frame
during the insertion of the edge of molding into the engaging
piece is supported by the protrusions 24. Thus, the possi-
bility of the clip breaking loose from the engagement byvirtue of this force is perfectly prevented.
The illustrated preferred embodiments of this invention
have been dçscribed. The clips of the present invention are
temporarily fastened individually to the edge of the window
frame by means of an adhesive tape or adhesive agent and
`thereafter are collectively immobilized by utilizing the ad-
hesive agent being used for adhesive engagement of the plate
of glass. The attachment of the plate of glass and the mold-
ing by use of the clips of this invention, therefore, can be
effected quite efficiently as compared with the conventional
method which involves preparatory attachment of studs for
footing, for example, and without the possibility of rusting.
Furthermore, the engaging piece intended to permit hooked
engagement of the molding is extended from the lower edge of
the base plate as described above and the engaging piece
itself is vested with ample resilience and is permitted to
function substantially independently. Consequently, if the
molding is brought into hooked engagement before the adhesive
agent has been thoroughly solidified, the resilient force of
- 20 -

the molding will neither cause the adhesive tape to come off
or move out of position nor make the molding break off from
the fast engagement. Thus, the clips of this invention have
an advantage that the work of attachment can be performed
quickly.
Further, since the aforementioned engaging piece is
formed so as to enjoy freedom of deformation, desired re-
placement of the molding alone can be obtained by forcibly
lifting the edge of the molding held in pressed contact with
the front side of plate of glass by a suitable tool, insert-
ing through the opening a prier or some other tool having a
hook at its leading end, hooking the prier on the ear portion
or recess formed in the engaging piece, pulling the prier to
bend the engaging piece toward the front side and thereby
breaking the engagement of the molding with the engaging
piece. In this case, the removal of the molding by the
procedure described above can be accomplished without in-
flicting any damage on the clip. Thus, the clips can be used
again. Reusability of clips proves highly advantageous for
the purpose of replacement of the molding or of adjustment to
be required during the attachment of molding.
