14 Claims. (Cl. 24-215)
This invention relates generally to fastener
elements, and refers‘particularly to snap fastener
devices of the type especially designed, for de
tachably securing trim panels and the like to
5 supports, such for example, as the framework of
motor vehicle bodies.
„
More particularly, thisinvention contemplates
on the plane -indicated by the line 'I-l of Fig
ure 4.
.
„
While it will be apparent as this description
proceeds, that the fastener element assembly
forming the subject matter of this invention `is 5
capable of many and diversified uses, neverthe
less, forthe purpose of illustration the same is
shown herein as employed for fastening the up
a fastener assembly of the type having a fastener
element and havingV means for anchoring the . holstery or trimming material panels to the

One of the principal objectsv of this invention attached. In the presentl embodiment- of the
consists in the provision of a fastener assembly' invention, the support S constitutes a portion of ‘ '
of the character set forth in the preceding para

graph, Wherein thevmeans for anchoring the fas-- provided with apertures I0 through which the
tener element to the trim panel also provides for fastener elements II project. As will be more
fully hereinafter set forth, thesize of the aper
20 relatively free universal movement of the fasten
er element relative to the trim panel in the plane tures I0 is predetermined in dependence upon
of the latter, and thereby permits the element to the size of the vfastener elements, so that. the
align itself with the aperture in the body frame-> latter will cooperate with the edges of the aper
work within which the same is adapted to be .en
tures to resilientlyv hold >the -trimp'anel into en
gaged.
'
.
Another advantageous feature of this inven
tion resides in the novel means- employed for>
yieldably resisting movement of the fastener ele
ment from an operative position substantially
30 perpendicular to the trim panel to an inoperative
- position substantially parallel to the panel.
A further advantageous feature of this- inven-l
tion resides in the novel ' construction of the
fastener assembly which' permits the same to be
35 economically manufactured, assembled and in
stalled.

.
'I-'he foregoing,-as well as other objects, will be
made more apparent as this description proceeds,
especially when lconsidered -in connection with
40 the accompanying drawing, wherein: ,
Figure 1 is a- fragmentary perspective view of
a trim panel having one of my improved fastener
assemblies attached thereto; _ y
y
Figure 2 is a sectional view showing the trim
45 panel‘in assembled relation with a support;
Figure 3 is a view similar to Figure 1` showing
the fastener element moved to inoperative po
sition;v

element employed in the assembly;

In the present instance, the fastener element
II is formed of a single strip of 4spring wire or
the like, bent. -intermediate its ends to form a
nose I2 predeterminedly proportioned with re
spect to the openings I0 to act as a pilot to fa
cilitate the insertion of the fastener elements
into the apertures I0 of the supporting struc
ture. Extending from the nose- I2 is a pair of
resilient legs I3 which >are .bowed intermediate
their length to form diverging portions Il lead 35
ing directly from the nose and to form converging
portions I5 at the ends of the Aportions I4. The
distance between the bowed intermediate portions
of the fastener element is greater'than the width
of the apertures I0 in the supporting structure 40
S, and the ends of the legs are free from con
nectionv with each other, so that insertion of the
>fastener element into one of the apertures I0
causes the legs I3 to spring toward one another.
suiiiciently to permit the bowed portions to pass '45
through the aperture. As soonas the bowed por
tions are extended through the aperture, the
legs are permitted to spring apart, due to the fact
that the portions l5 of the legs converge. to re
siliently engage the opposite edges of the aper
ture, as is well known in this art.

As will be observed. particularly from Figure 5,
the extremities of the legs I3 of the fastener ele
ment terminate in oppositely projecting substan
tially cylindrical extensions I6 forming means for 55

attaching the fastener element to the retainer or
anchorage unit I1 about to be described. The
anchorage unit I'I comprises a sheet metal stamp
ing is of such a nature as to actually prevent this
vide for securing the plate to the backing B of
the trim panel. The portions 2I of the plate I3
forming the opposite longitudinal sides of the
limited flexing of the disk, it will be apparent
that the portions 2i of the anchorage plate I3
will flex sufficiently to eiîect'the desired' action
previously set forth.- In any event,l the construc
tion is such as to yieldably prevent accidental
swinging movement of the fastener element from
its operative to its inoperative position, and to
permit this movement by a flexing of either or
the plate to provide aligned recesses`22 in'. the
plate.
underside of the pla'te for receiving the exten
sions I6 on the fastener element II. 'I'he exten
chorage plate I8 are provided with prongs 20
ing I8 in the form of a plate having a rec
tangularly shaped opening I9 'therethrough and
having prongs 2li- at the corners thereof to pro
10 opening I9 are bent laterally out of the plane of _ both of the disk and portions 2| of the anchorage l0
sions- I E are retained Within the recesses 22, by
,15 means of a spring metal disk 23 engaging the
underside of the plate 'I8 and permanently `se
cured thereto by means of legs 24 formed integral
with the plate I8. As shown in Figure 7, the re
cesses 22 are elongated in the direction of length
20 of the plate, or in other words, in a direction
transverse Yto the extensions I6, so as to not only
permit relatively free angular movement of the
fastener element relative tothe retainer assem
bly, in the plane of the trim panel, but to also
25 permit shifting the element in said plane longi
tudinally of the plate I3. In addition, attention
is directed to the fact that the distance between
the recesses 221s greater than the free ends of
the legs I3 of the fastener element II, so as to
30 provide for shifting the element in the plane of
the trim panel transversely of the plate I3. The
foregoing is of particular importance in the
present application of the fastener element, since
it permits the latter to align itself with respect to
3,5 the opening I0 in the supporting structure S.
It will be apparent that the foregoing con
struction also permits the -fastener element II to
be swung from an operative position perpendicu
lar to the anchorage plate I8 to an inoperative po
40 sition substantially parallel with this plate, so
as to permit stacking the trim panels without in
terference from the fastener element assemblies.
In the present instance, swinging movement of
the fastener element from its operative to its in
45 operative position is resisted sufficiently to pre
vent this movement from taking place acciden
tally upon applying the trim panel to the sup
porting structure. 'I'his latter feature is accom
plished in the present instance, by providing flats
50 25 on one or both- of the extensions I3.
In the
As previously'stated, the corners of the an
adapted to be projected into the backing mem
ber B of the ,trim panel to secure the fastener 15
assembly to the latter, and in the present in
stance, provision is made for securing the as
semblies to the backing member adjacent the
marginal edges thereof. The above is accom
plished in the present instance by inclining the' 20
corners of the anchorage plate, provided with the
prongs, inwardly with respect to the longitudinal
media'n line of the plate at such an angle that
the prongs will pierce the backing a substantial
distance inwardly from the marginal edge of the
latter even though one side edge of the plate
coincides with‘this marginal edge.
Referring now to the operation of my improved
fastener assembly and assuming that the fastener
element is in its inoperative position shown in 30
Figure 3, it will-be noted that when it is desired
to assemble the trim panel with a supporting
structure, each of the elements is first swung
about the axis of the attaching portions I6 from
its inoperative position substantially parallel to 35
the panel surface to its inoperative position sub
stantially perpendicular' to this surface. The
trim panel equipped with the fastener elements
may then be secured to the supporting structure
S by engaging the fastener elements II with the ~
apertures Ilivformed in the supporting structure.
During engagement ofthe fastener elements with
the apertures, the leg portions I3 are moved to
ward one another, as previously explained„but `
swinging movement of the fastener elements out
of their perpendicular planes is resisted by rea
son of the fact that in the operative position of
the fastener elements, the opposed flats 25 on the
extensions IB respectively engage the disk 23 and
portions 2I of the anchorage plate I8. It will

plate to a position substantially parallel with

flexible disk 23.
Inasmuch as the extensions I3
65 engage the portions of the flexible disk midway
between the securing lugs 24, and in view of the
fact that the disk is of relatively light gage spring
metal, it .necessarily follows that the disk may be
flexed by the extensions without exerting undue
70 force on the leg portions I3 of the fastener ele
ment. While the slight ilexure of the Ydisk re-_-

been described and illustrated herein, somewhat
in detail, it will be readily apparent to those
skilled in this art that various changes 'in the
details of construction may be resorted to without 70
departing from the spirit and scope of this in
vention, and to this'end reservation is made to
make such changes as may come within the pur
view of the‘accompanying claims.
