A cap stacking structure comprises a plurality of caps. Each cap
has at least one axial ribs for stacking the plurality of caps
together so that the plurality of caps are stacked along an axial
line passing through an axial center of each cap; and gaps between
two adjacent caps have a predetermined length. Each rib is extended
from a periphery of each cap. One side of each cap is formed with a
protruding round end and another side of each cap is formed with a
groove having a shape with respect to the protruding round end.
Thereby, the plurality of caps are stacked by the coupling of the
protruding round end and groove.

Description
FIELD OF THE INVENTION
[0001] The present invention relates caps of nail guns, and
particularly to a cap stacking structure.
BACKGROUND OF THE INVENTION
[0002] In the pneumatic nail gun, caps are pushed to a beating
position automatically so that the caps can be beaten continuously
to an object. The prior arts, U.S. Pat. No. 5,947,362 and U.S. Pat.
No. 6,145,725, disclosed nail guns with above said function. In
these prior arts, the caps are stacked horizontally and coaxially
and then the caps are placed in a cap case. Then the cap case is
installed on a guide track. Since the caps are installed
horizontally so that gaps between caps are larger so that only a
few caps are contained in the guide track. As a result, the cap
case must be enlarged so that the volume of the nail gun is
increased. As a consequence, the operation is inconvenient.
[0003] Moreover, in another prior art, a vertical cap collecting
cylinder is developed. In this prior art, a plurality of caps can
be placed in the cylinder. The caps can be outputted from one
opening of the cylinder for being beaten. This prior art is
beneficial for reducing the volume and the user can hold it easily.
However, in this prior art, the caps are irregularly placed in the
case one by one so that the operation for filling the caps is
inconveniently.
[0004] Thereby, these prior arts can not resolve the problems of
increasing volumes for receiving caps and difficulty in
operation.
SUMMARY OF THE INVENTION
[0005] Accordingly, the primary object of the present invention is
to provide a cap stacking structure which comprises a plurality of
caps. Each cap has at least one axial ribs for stacking the
plurality of caps together so that the plurality of caps are
stacked along an axial line passing through an axial center of each
cap; and gaps between two adjacent caps have a predetermined
length. Each rib is extended from a periphery of each cap. One side
of each cap is formed with a protruding round end and another side
of each cap is formed with a groove having a shape with respect to
the protruding round end so that the plurality of caps are stacked
by the coupling of the protruding round end and groove.
[0006] The various objects and advantages of the present invention
will be more readily understood from the following detailed

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0022] Referring to FIG. 1, a perspective view about a preferred
embodiment of the cap stacking structure is illustrated. The cap
set 1 is formed by a plurality of caps 11. Each cap 11 may have a
round shape or other geometry shape. The periphery of each cap 11
is extended with a plurality of rib ends 12 (referring to FIG. 2).
By the rib ends 12 to connect the cap 11 with the cap 10, a
plurality of caps 11 are connected as a cap set 1.
[0023] By the rib ends 12 of the caps 11, the caps 11 are staked
along a coaxial axis 14 (referring to FIG. 3). The adjacent cap 11
and cap 10 is formed with a gap of h0 so that the whole cap set 1
is filled in the cap case (will be described hereinafter) of a nail
gun, Thereby, the caps 11 can be guided precisely.
[0024] In another embodiment of the present invention, the cap 101
of the cap set 100 can be made with a shape of a rectangular cover
with cambered corners (referring to FIGS. 3A and 3B). The axial rib
ends 103 are used to connect the cap 101 with the cap 102. The
plurality of rib ends 103 are arranged around the periphery of the
cap 101 so that the caps 104 are stacked along the same axial line
104 with a gap therebetween so as to form a cap set 100.
[0025] Other than above embodiment, FIGS. 4 to 6 shows another way
for stacking the caps. In this embodiment, a plurality of caps 21
are serially connected as a cap set 2 (referring to FIG. 4). Each
cap 21 has a shape of a round cover or other cover shape. A center
of a bottom of each cap 21 is formed with a protruding round end 22
(referring to FIG. 6). A top center of each cap 21 is formed with a
groove 23 corresponding to the protruding round end 22. Then by the
coupling of the protruding round end 22 with the groove 23, two
adjacent caps 21 are assembled together so as to form a cap set
2.
[0026] To use the groove 23 effectively, the depth of the groove 23
can be increased by forming an annular rib 29 along an opening of
the groove 23 (referring to FIG. 6A) so as to increase the
stability of the caps 21.
[0027] In another design, a top center of each cap 28 is protruded
with a protruded round end 25 (referring to FIG. 6B). A bottom
center of each cap 28 is formed with a groove 26. Thereby, by the
coupling of the round ends 25 and the grooves 26, adjacent caps 28
are serially connected as a cap set. Moreover, an annular rib 29
can be formed at the periphery of the opening of the groove 26 of
the bottom of the cap 28.
[0028] Moreover, in this embodiment, a plurality of caps 28 are
stacked along an axial line 24 and edges of two adjacent caps 28
are formed a gap h1 (referring to FIGS. 6, 6A and 6B). Thus the
whole cap set 2 are filled in the cap case (will be described
hereinafter) so as to guide the cap precisely and smoothly.
[0029] In the embodiment illustrated in FIGS. 4 to 6, the groove 23
can be formed with a through hole 27 at a bottom of the groove so
that a plurality of caps can be serially connected by a tie device
passing through the through holes of all the caps in the cap
set.
[0030] Referring to FIGS. 7 and 8, a horizontal cap case 4 (shows
in FIG. 7) and an inclined cap case (shows in FIG. 8) for filling
the cap set 1 or 2 are illustrated. The cap case can be used to
fill the cap set 1 or 2.
[0031] When the cap set 1 or 100 of the rib ends 12 or 103 of the
present invention are filled into the horizontal cap case 4
(referring to FIG. 6) or inclined cap case (referring to FIG. 7),
for example, for a cap set 1 with the rib end 12, a cutter 42 is
embedded into the gap h0 between the cap 11 and cap 10 (referring
to FIG. 3) for cutting the rib end 12. Thereby, each cap 11 can be
transferred by pliers 43 and then to a beating opening 61 of the
nail gun 60. The gap h0 has a further effect of receiving the
cutter 43 and guiding the cap 11 precisely.
[0032] When the cap set 2 of the present invention having the
protruding round end 22 and the groove 23 is filled in the
horizontal cap case 4 (referring to FIG. 9) or the inclined cap
case 40 (referring to FIG. 10), a rod 44 can be installed at a cap
outlet 41 of the casing, when the cap is beaten, the rod will move
the cap 21 to the beating opening 61 of the nail gun 60. The gap h1
has the function of embedding the rod 44 and guiding the cap 21
(referring to FIG. 6).
[0033] The cap set 2 with the protruding round end 22 and groove 23
can be filled to a cylindrical cap case 5 (referring to FIG. 11).
When the nail beat rod operates, a claw or teeth device 52 at an
opening 51 of the cap case 5 is embedded into the gap h1 between
the cap 21 and the cap 20 (referring to FIG. 6) so as to release
the cap 21. Then a push plate 53 at the opening of the cap case
pushes the cap 21 to the beating opening 63 of the nail gun 62.
[0034] The scope of the present invention is at the configuration
of the cap instead of the application of the cap case. Moreover,
the way for guiding the caps is not used to confine the scope of
the present invention.
[0035] The gaps h0 and h1 have the effects of guiding the cap set
so that the nail can be guide precisely. Since a plurality of caps
are stacked along an axial center of the cap set, the cap set 1 can
be placed in the cap case easily and conveniently.
[0036] The arrangement for stacking the caps is beneficial to
collect a plurality of caps within one cap case so that only one
cap set is necessary to be placed in the cap case. Thereby, the
caps can be beaten continuously.
[0037] The present invention is thus described, it will be obvious
that the same may be varied in many ways. Such variations are not
to be regarded as a departure from the spirit and scope of the
present invention, and all such modifications as would be obvious
to one skilled in the art are intended to be included within the
scope of the following claims.
