COVER CAPS WITH PEGS FOR INSERTING IN A SERIES OF HOLES
Abstract
Improved integral strip of pegs with cover caps for furniture
production and mounting. A plurality of such pegs in predetermined
distances from one another are supported by a common integral strip
and can be inserted in a row of holes at the surface of the
furniture by striking over the strip, the latter being disposed to
be broken out along prepared breakout lines around the
circumferences of said caps.

Claims
What I claim is:
1. An elongated planar strip of flexible plastic material having a
plurality of capped pegs integrally formed therewith, said pegs
being spaced at regular intervals along the longitudinal axis of
said strip, said pegs being spaced on predetermined centers along
said axis, said pegs being insertable into holes for closing said
holes, said holes being spaced in correspondence to the spacing of
said pegs, said caps lying against the openings of said holes when
said pegs are inserted in said holes, each of said caps having
circular breaking lines along the entire circumference thereof for
manually severing said caps from said strip after insertion of said
pegs into said holes, said caps having convex heads extending out
of the plane of said strip, said breaking lines weakening the
adherence of said caps to said strip so that said caps are
severable from said strip by application of unaided manual force.
Description
BACKGROUND OF THE INVENTION
In order to save the time of skilled craftsmen, rows of holes have
been provided in furniture at the inside wall surfaces support pegs
can be inserted into which at desired spacing bearing pins to
support intermediate shelf-plates, hinges, etc.
It is often customary to cover the unused holes by caps but a
considerable time for closing every single hole is necessary.
Therefore many furniture producers tolerated the presence of rows
of open holes despite their unsightly appearance.
SUMMARY
The present invention relates to means for covering rows of holes
in a new and essentially more economic manner. The is achieved by
providing a plurality of caps with pegs in spaced apart distances
corresponding to rows of holes supported by a common strip with
prepared break points, whereby the strip, after the pegs are
inserted into the holes, is merely torn off. Thus the strip to
which the caps are preferably integrally molded is inserted with
the first peg thereof into the first hole and then is struck over
the row of the holes. Since the distance of the caps is adapted to
that of the holes, the holes within seconds are closed more or less
automatically. The caps are preferably provided with the decor of
the wall surface of the furniture, so that a pleasant overall
surface of the walls of the furniture is attained. The lengths of
the strips depend obviously on the actual mode of of the furniture
production, of the machine tools and must be pre-planned from case
to case.
Various further and more specific purposes, features and advantages
will clearly appear from the detailed description given below taken
in connection wit the accompanying drawings which form part of this
specification and illustrate merely by way of example embodiments
of the device of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now in more detail to the drawings illustrating preferred
embodiments by which the invention may be realized, there is shown
in FIG. 1 and 2 a plastic strip 1 with a layout according to the
surface of the inner wall of the furniture. Pegs 2 are formed on to
the strip by a molding tool not shown. Simultaneously breakout
points or break-away lines 3 are produced by the same tool for the
production of the caps 4. When such a strip of a certain length for
example 8 feet is applied with the first peg 2 to the first hole of
a vertical row holes, all subsequent pegs 2, each one lying
automatically before a hole, may be pressed in by striking over the
strip by hand without additional auxiliar means. Thereafter the
strip, which is provided with the prepared break-out lines, can be
simply pulled off, so that the entire row of holes is correctly
closed at once. By a proper shape of the molding tool a peg of the
shape as shown in FIG. 3 can be also obtained wherein the cap has a
certain convex shape in order to adhere to the wall furniture by
suction.
In view of the fact that in the embodiments of FIGS. 1 - 3 much
strip material is wasted, it is also possible according to FIG. 4
to arrange on that one plastic strip a meandering cut line 5
whereby two cap strips 6 and 7 are simultaneously produced. FIG. 5
shows in crossection the separated strips 6 and 7, and FIG. 6 shows
a similar section with convex caps'.
A still more advantageous separation into two strips 8 and 9 is
shown in FIG. 7. In this case the caps 4, 4' are joined to the
strips only at nearly pointlike break-out areas 10 and 11 and are
cut at the remaining circumference, while the final separation of
both strips is obtained by the cuts 12. The prepared break-out
areas 10, 11 are situated at such positions on the circumference 3
of the caps where the latter runs approximately parallel to the
longitudinal direction of the strip. By this arrangement the
eventual removing of the strip is much facilitated.
According to FIG. 7 a the break-out lines 12' furthermore can be
positioned so that they actually end at the break points 10 and 11,
in order to minimize the irregularities on the circumference of the
cap and for simplify the tool. By using the constructions of FIG. 7
and 7a and in view of FIG. 4, a considerable amount of strip
material can be saved.
When the distances of the holes and the diameters of the caps
permit it even four strips of caps may be produced from one plastic
foil.
In all embodiments which have been described above the method of
production can be also continuously performed, that is instead of
and 8 foot long strip being molded in a corresponding long form,
which would be very expensive and only possible under great
difficulties as to molding techniques, an endless strip may be lead
through a molding form so that one or preferably a plurality of
peg-sockets are formed simultaneously and the strip accordingly
advanced to form the next sockets .
Eventually lengths of strip with equal peg distances can be cut
off. Obviously also more than one strip, for example 5 or 10 can
run through side by side each one of the inserted strips being
suitable to yield a double strip with caps.
Another process for reducing the tool dimensions is represented in
FIG. 9 and 10. In this case the strip 1 is wound on a movable part
13 and then by unwinding about pivot 14 is enclosed between two
molding halves 15 and 16 whereupon pegs 6' are formed thereon.
In many instances it is sufficient, to form caps colorless without
decor design or in one color only similar to the color of the wall
surface of the furniture as close as possible. In such case a pair
of paper strips 19 and 20 may serve as a support or there may be
caps 4 being formed on both sides of the strip 21 as shown in FIG.
12. The paper strips may run at the underside of the caps so that
they do not affect the upper surface of the cap. In case of FIG. 12
the strip is used in such manner that at first one row of caps is
inserted into a row of holes whereby the other row of caps makes
way automatically. After removing the supporting strip from the
first row of holes the rest is available for a further row of
holes.
FIGS. 13 - 20 show various crossections of caps with pegs thereon.
In FIG. 14 a convex cap 4' with a smooth cylindrical hollow peg 6'
is shown, The latter may be slotted and is dimensioned so that it
can be fitted in a prepared hole of the row of holes.
FIGS. 14-20 show various other arresting means such as barb-noses
22 (FIG. 14), elongated rectangular noses 23 near the end of the
peg (FIG. 15), semi-spherical bosses 24 (FIG. 16), pyramid-shaped
bosses 25 (FIG. 14), cone-shaped bosses 26 (FIG. 18), oval-shaped
ribs 27 (FIG. 19), or elongated rectangular barb-noses in the
central part (FIG. 20).
According to FIG. 21 each cap 4 has in addition to the
circumferential break-out line 3 a further central break-out line
29, the diameter of which corresponds to the inner bore 30 of the
peg 2'. The disc 31 which is formed thereby may be used as a
self-locking wedge for an inserted support pin 32 in the bore 30
for a shelf board or the like.
FIGS. 22 and 23 show the possibility to arrange caps at close
distances from one another in a strip 33. By this arrangement more
pegs than in former cases may be placed on a given length of strip.
When the caps are inserted in a row of holes, the distances are not
quite correct but since all caps are attached to a common strip,
also in this case a mounting advantage is still obtained.
