Referring to the drawings, there is illustrated

derstood that the trim panels may be of different
shapes and sizes and may be mounted at other
vlocalities on the inside of the body.
Referring particularly to Figs. 2 and 11 to 13 35
inclusive, the fastener C in the present form
thereof comprises as a one-piece device a body
or shank portion generally indicated at 20 hav
ing at its rear end an upstanding shoulder or
offset portion 2| terminating in a rearwardly di
rected horizontal tongue or flange 22. The for
ward edge of the body or shank portion 20 has an
extension 23twhich provides a horizontally pro-.

It will be un
in the plane of the bottom surface of the shank
20. At the juncture of the tongue or lug 23 and
the body 20 there rises a vertically extending por- ‘
bend 25 providing a spring bow. The part 25 ‘ex
tends forwardly and' downwardly and‘ then is 50
?ared upwardly ‘to produce a curved gripping
portion 26 and an upwardly inclined lead portion 7
21. The parts‘ 25, 26 ‘and 21 thus provide a'spring '
gripping member which by reason of the spring
bow 25 will enable‘the member‘ tobe bent or

sprung outwardly under tension so as to permit
the curved intermediate portion 26 thereof to
engage and grip the ?ange portion of the sup
porting frame.
The trim fastener C is applied and. assembled
with a trim panel which in the present instance
comprises a foundation or backing sheet 29 of
?ber board or other suitable material. The face
of the backing sheet is covered by means of pad
10 ding material 30 of jute or other ?brous sub
stance and this layer is in turn covered with
trim fabric 3| which is folded around the edge of
the foundation sheet 29 as indicated at 32 and
cemented at the rear face of the foundation sheet
15
20
along the edges thereof. At suitable points along
the side and bottom edges of the trim panel and
inwardly of the cemented edges of the fabric ma
terial the foundation sheet 29 is provided with
holes or slots therethrough which in the present
instance are substantially rectangular in'shape.
These holes are substantially the area and shape
of the body or shank portion 20 of the fastener
so that when the fastener is installed the shank
portion will preferably entirely ?ll and close the
25 hole.
The fastener may be readily assembled on
the trim panel in the manner illustrated in Fig. 3
by ?rst inserting the tongue or lug 23 into the
hole so as to extend beneath and- underlap the
forward edge of the hole. The heel 2| of the
30 fastener or the rear edge thereof is then pressed
downwardly so as to force the shoulder 2| into
the hole 33 so as to provide a ‘tight ?t of the
shank portion 28 and the upstanding portions 2|
and 24 around the edges of the hole. The front
35 corners of the tongue 23 are preferably bent up
slightly as shown at 28 so as to permit this tongue
to be inserted between the foundation sheet 29
and the padding 3|) without snagging and so as
to cause these corners to embed into the under
face of the ?ber board 29 as illustrated in Fig.2.
When the fastener is thus installed it will be seen,
as shown in Fig. 2, that the tongue or lug 22 over
lies the rear edge of the hole 33 and the tongue
or lug 23 underlies the forward edge of the hole.
As a consequence, when the gripping end 26 of
the fastener is bent outwardly relative to the
shank 28 the fastener will be, held against re
moval due to the bearing of the parts 22 and 23 at
opposite sides or opposite ends of the aperture in
50 the panel. It will also be seen that the shank or
body portion 29 ?ts snugly within the hole, en
tirely ?lls it, and lies substantially ?ush with the
under-face of the sheet 29. As illustrated in Fig.
14 the foundation sheet 29 at its under-face may
55 be provided with an embossed groove or depres
sion of sufficient depth so that the tongue 23 will
?t therein and permit‘ the base of the fastener to
lie exactly ?ush with the under-face of the
sheet 29 thereby providing a smooth uninter
rupted surface.
In the present instance the trim panel is as
sembled on the vehicle door A. As illustrated in
Fig. 2 the door comprises an outer body panel 34
attached in the usual manner to the upright pil
65 lar 33 which at the rear side thereof has an in
ers over the back face of the ?ange, as illustrated
in Fig. 2, this portion being sprung out during
the operation so as to grip the ?ange under ten
sion. The panel may then be bowed outwardly to
a su?icient extent to permit the fasteners at the
opposite vertical edge to engage behind the edge
of the ?ange 36. By ?attening out the panel the
fasteners will be forced into gripping engagement
with the ?ange. The panel may then be slid ,
downwardly so as to cause the fasteners at the 10
lower edge thereof to engage behind the bottom
?ange of the door.
One manner or method of forming the fastener
C will now be described. A ?at blank of metal is
?rst formed or cut into the shape shown in Fig. 4, 15
comprising a main portion 31, a forwardly ex—
tending tongue portion 38, a rearwardly extend
ing tongue 39, laterally projecting portions 31a
and 31b, together with a short front extension or
portion 23, all of said portions lying in the same 20
plane. The blank so formed is now preferably
placed in a press and the extension 38 bent down
from the line 40 to the shape shown in Fig. 6, and
the tongue 39 is bent along the line 39a so as to
provide the abutment or shoulder 2| forming the 25
heel of the fastener and a rearwardly extending
tongue or ?ange 22. During this operation the
free- edges of the tongue 23 are preferably bent
up slightly as shown at 28. The next operation
is to bend the portions 38 and 31a along the line
4| at a right angle to the base portion 31 and 30
to bend the lateral extension or portion 311) along
the line 42 also at a right angle to the base por
tion 31. These operations result in the produc
tion of the structure illustrated in Figs. 7 and 8. 35
The next step is to bend the portion 31a to over
lap and lie ?at against the upper face of the por
tion 31 (see Figs. 9 and 10) in which position it
will be noted that the shaped tongue 38 of the
fastener has had its position completely reversed
from that in which it is shown in Figs. 5 and 6. 40
Inother words, the tongue has been turned com
pletely over. The next step is to fold over the
lateral portion 31b to overlie the adjacent edge of
portion 31a and thus complete the fastener as 11
lustrated in Figs. 11 to 13 inclusive.
_

The construction of the fastener is preferably
such that when installed on the foundation sheet
of the panel the base of the curved gripping por
tion 26 will lie su?iciently close to the rear face
of the foundation, or substantially in contact 50
therewith if desired, so that the ?ange 36 of the
support will, when projected between the part
26 and the rear face of the foundation, spring
the gripping member outwardly and place it un
der tension. When the fastener is installed in 55
the panel aperture the heel 2|, when forced into
the aperture,_ will frictionally engage the rear
edge of the aperture and produce .sui?cientbind
ing action as to hold the fastener in place by
friction. The fastener may be readily removed 60
by ?rst drawing out the heel 2| to‘ tilt the fas
tener and then withdrawing it by a straight line
or rectilinear pull in a rearward direction exact
ly reverse to the manner of installation.
