PANEL FASTENER CLIP
Abstract
The present invention relates generally to spring type fastener
clips, and more particularly to improvements in fastener clips of
the type adapted to accommodate the margins of panels. The
embodiment disclosed herein includes a sheet metal stamping
presenting an elongate relatively narrow base section and laterally
yieldable converging panel engaging wing members extending from
opposite longitudinal margins of said base section. The opposite
extremities of the outer marginal edges of said wing members
diminish in distance from the base section to facilitate initial
reception of a panel margin, and integral struck-out panel
attachment prongs extend from the base section in a direction
opposite to the wing members.

claim 1, wherein the outer edges of the wing members progressively
diminish in distance from a central intermediate location of said
base to opposite points in the vicinity of said base
extremities.
3. A fastener clip for attachment to a panel margin as set forth in
claim 2, wherein the outer edges diminishing in distance from the
base define a curve, the opposite extremities of which terminate
adjacent the base extremities.
4. A fastener clip for attachment to a panel margin as set forth in
claim 1, wherein the integral attachment means comprise prongs
struck from the fastener base.
5. A fastener clip for attachment to a panel margin as set forth in
claim 4, wherein said struck-out prongs are generally arcuate in
transverse cross section.
6. A fastener clip for attachment to a panel margin as set forth in
claim 4, wherein the struck-out prongs present pairs of work
engaging faces facing toward each other.
7. A one-piece sheet metal fastener clip for attachment to a panel
margin including an elongate relatively narrow base section,
normally converging laterally yieldable panel engaging wing members
extending from opposite longitudinal margins of said base section,
said wing members comprising flat sheet metal sections, the outer
edges of which define a curve extending from a point adjacent one
extremity of said base to a point adjacent the opposite extremity
to said base section whereby to facilitate initial reception of a
panel margin between said wing members in the vicinity of said base
section, and integral spaced panel attachment means in the form of
members struck from the base section and extending therefrom in a
direction opposite to said wing members.
Description
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a novel and
very practical spring type clip adapted to support panel members in
a vertical position. Panels in the form of perforated sheets
commonly referred to as pegboard sheets, are often employed to
provide partitions in display cases and the like. The present
invention contemplates a spring clip of improved and simple
construction which particularly lends itself for use with such
perforated panel stock.
More specifically, the present invention contemplates a fastener
clip of the type referred to above which may be produced in the
form of a sheet metal stamping of minimum size which may be
initially associated with a panel margin without the potential
hazard of structurally impairing or defacing the panel margin
during such association. To this end the present invention
contemplates a U-shape type spring panel clip having oppositely
disposed openings uniquely shaped to facilitate initial association
of a panel margin with the clip.
It is a further object of the present invention to provide a spring
fastener clip as set forth above having a novel arrangement of
panel attachment means particularly applicable to perforated or
pegboard stock.
The present invention also contemplates a spring clip fastener for
panel margins which may not only require a minimum amount of sheet
metal stock, but which also may be produced by the practice of
conventional stamping and forming methods, thus reducing the cost
of manufacture to a minimum.
BRIEF DESCRIPTION OF THE DRAWING
The foregoing and other objects and advantages will be more
apparent from the following detailed description when considered in
connection with the accompanying drawing wherein:
FIG. 1 is a perspective view of a display case equipped with panel
engaging spring clips of the type contemplated by the present
invention;
FIG. 2 is a perspective view showing one of the partitions detached
from the display case of FIG. 1, more clearly to illustrate the
manner in which the spring clips may be associated with the panel
margins;
FIG. 3 is an enlarged fragmentary sectional view taken
substantially along the line 3--3 of FIG. 1;
FIG. 4 is a top end view of the clip detached from the panel
member;
FIG. 5 is a perspective view of the detached clip;
FIG. 6 is an elevation of the clip as seen from the left of FIG.
5;
FIG. 7 is a fragmentary perspective view disclosing the manner in
which a panel margin may be initially associated with the U-shaped
spring clip; and,
FIG. 8 is a fragmentary end view seen from the right of FIG. 3,
disclosing the slightly arcuately formed prongs or tongs
interlocked with the perforated panel.
Referring now to the drawing more in detail wherein like numerals
have been employed to designate similar parts throughout the
various figures, it will be seen that one embodiment of a panel
accommodating spring clip is designated generally by the numeral
10. The spring clip 10 is in the form of a sheet metal stamping
including an elongate relatively narrow base section 12. A pair of
converging wing members 14 extend from opposite longitudinal
margins of the base section 12. Vertically spaced panel attachment
members or prongs 16 are struck from the base section 12, in a
direction opposite to the wing members 14. The spacing of the
prongs or tongues 16 is such that they will register with
complementary, similarly spaced apertures or perforations 18 of a
partitioned display case designated generally by the numeral 20. A
panel section of the display device 20 is designated in FIGS. 1 and
2, by the numeral 20a.
Perforated board of the type illustrated herein is readily
available, and the spacing of the apertures in the board material
standardized. The spring clip of the present invention has a very
practical application to board material of this type. The prongs or
tongues 16 are spaced so as to accommodate a pair of board
apertures as clearly shown in the drawing. Attention is directed to
the fact that it is preferable to form the prongs 16 so that they
are generally arcuate in cross section as is clearly illustrated in
FIG. 8. The prongs 16 thus provide pairs of work-engaging edges
facing each other which are adapted to impinge the edges of the
panel defining the complementary apertures 18. The embodiment of
the prongs shown by solid lines in the drawing, as for example in
FIG. 3, have an approximate length, corresponding with the
thickness of the wall or partition of the display case 20. In
instances where necessary, these prongs may be longer and bent
laterally against the outer surface of the wall as shown by the
dotted lines in FIG. 3.
In the preferred embodiment of the clip the distance between the
inner surfaces of the wing members 14 in the vicinity of the base
12, is substantially equal to, or slightly larger than, the
thickness of the workpiece or panel 20a. Thus as illustrated in
FIG. 3, the initial association of the corner of the panel 20a, is
greatly facilitated by having the converging wing members 14 formed
with arcuate or curved outer edges. Thus the outer edges of the
wings 14, from a point intermediate the opposite extremities
thereof, progressively diminishes in distance from the base 12, as
said edges approach the complementary extremity of the base. In
this manner the presence of the sharp corners is eliminated, and
the potential danger of marring or impairing the surface of the
workpiece, or panel, is reduced to a minimum. The arcuate contour
of the outer edges of the converging wing members 14 serves to
guide the panel into association with the clip and thus greatly
facilitate the ease with which such assembly may be accomplished.
As the wings 14 are forced apart, they ultimately impinge the
entire inner surfaces of the wings.
From the foregoing it will be apparent that the present invention
contemplates a spring clip device of extremely simple, yet
practical form. The curved contour of the wing edges not only
facilitate initial association of a panel with a clip as previously
described, but also make it possible to produce the clip from a
minimum amount of metal stock without sacrificing gripping
effectiveness. In many instances the prongs may be used without
folding the projecting portions thereof over the panel stock
because of the firm impingement of the arcuately disposed prongs
with the apertured panel stock.
