structure in accordance with the present invention is shown
comprised of a base member 1, a plurality of retaining members 2, a
plurality of swivel locking control members 3, and a gun body
4.
[0016] The base member 1 has a longitudinal coupling groove 11
disposed at one side, namely, a platform 12 disposed at the other
side, namely, the top side opposite to the bottom side, a plurality
of locating holes 111 and through holes 112 respectively extending
from the coupling groove 11 to the outside of the base member 1, a
transverse locating block 113 extending across the longitudinal
coupling groove 11, and a plurality of locating blocks 13 protruded
from one lateral side corresponding to the through holes 112.
[0017] The retaining members 2 are made out of an elastic material,
each having two springy clamping arms 21.
[0018] The swivel locking control members 3 each have a bottom
block 31, a camshaft 32 protruded from one side of the bottom block
31, an angled locking block 33 extending from the periphery of the
camshaft 32, a mounting rod 34 axially extending from one end of
the camshaft 32 opposite to the base block 31, and a handle 35
affixed to the mounting rod 34 with a pin 36 for rotating the
respective swivel locking control member 3 relative to the base
member 1. Further, a return spring 331 is coupled between the
angled locking block 33 and the base member 1.
[0019] The gun body 4 comprises a top coupling bar 41. The top
coupling bar 41 has a plurality of transverse grooves 42 and
transverse tongues 43 alternatively arranged in parallel along the
length of the top wall thereof.
[0020] The retaining members 2 are respectively mounted in the
locating holes 111 of the base member 1 to suspend the respective
clamping arms 21 in the coupling grooves 11 at two sides. The
swivel locking control members 3 are respectively pivoted to the
locating blocks 13 of the base member 1 to insert the respective
angled locking blocks 33 into the through holes 112 of the base
member 1. By means of the respective handle 35, the user can bias
the camshaft 32 of each swivel locking control member 3, moving the
respective angled locking block 33 in and out of the respective
through hole 112. The coupling groove 11 of the base member 1 is
adapted to secure the top coupling bar 41 of the gun body 4. When
the top coupling bar 41 is attached to the coupling groove 11 of
the base member 1, the clamping arms 21 of the retaining members 2
are respectively clamped on two opposite lateral sidewalls of the
top coupling bar 41 of the gun body 4, and the transverse locating
block 113 is engaged into one transverse groove 42 of the top
coupling bar 41, and thereafter the swivel locking control members
3 are respectively biased to force the respective angled locking
blocks 33 out of the respective through hole 112 and stopped
against the top coupling bar 41, locking the top coupling bar 41 to
the base member 1.
[0021] The coupling groove 11 of the base member 1 can be made
having a U-shaped or I-shaped groove, a dovetail groove, or any of
a variety of other configurations. The top coupling bar 41 is
configured to fit the coupling groove 11. Further, pins, screws, or
other equivalent members may be used to substitute for the swivel
locking control members 3 for locking the base member 1 and the top
coupling bar 41 together.
[0022] Referring to FIGS. 5.about.8, the base member 1 is a single
size design. The size of the top coupling bar 41 is determined
subject to the type and size of the gun body 4 of the (toy or real)
gun. By means of the clamping arms 21 of the retaining members 2
and the swivel design of the swivel locking control members 3, the
base member 1 can be locked to any of a series of sizes of top
coupling bar 41 that is receivable to the coupling groove 11 of the
base member 1. Further, the return springs 331 hold the respective
angled locking blocks 33 in the locking position. Further, a laser
sight, infrared sight, night-vision sight, or any of a variety of
other gun attachments may be carried on the platform 12 of the base
member 1. FIG. 8 shows an application example of the present
invention, in which a night-vision sight 5 is mounted on the
platform 12 of the base member 1.
[0023] In general, the gun attachment mounting structure of the
present invention has the following features and advantages:
[0024] 1. After the coupling groove 11 of the base member 1 is
coupled to the top coupling bar 41 of the gun body 4, the
transverse locating block 113 of the base member 1 is engaged into
one groove 42 of the top coupling bar 41 to stop the base member 1
from horizontal displacement in longitudinal direction relative to
the top coupling bar 41, and the clamping arms 21 of the retaining
members 2 are clamped on the two opposite lateral sides of the base
member 1 to stop the base member 1 from horizontal displacement in
transverse direction relative to the top coupling bar 41, and the
angled locking blocks 33 are stopped against the top coupling bar
41 to stop the base member 1 from vertical displacement relative to
the top coupling bar 41, and therefore the base member 1 is firmly
locked to the top coupling bar 41.
[0025] 2. The clamping arms 21 of the retaining members 2 are
elastically movable in the respective locating holes 111 of the
base member 11, and the angled locking blocks 33 are movable in the
respective through holes 112 of the base member 11, and therefore
the clamping arms 21 and the angled locking blocks 33 can lock the
base member 1 to a different size of top coupling block 41.
[0026] A prototype of gun attachment mounting structure has been
constructed with the features of FIGS. 1.about.8. The gun
attachment mounting structure functions smoothly to provide all of
the features disclosed earlier.
[0027] Although particular embodiments of the invention have been
