Description
BACKGROUND OF THE INVENTION
[0001] (a) Technical Field of the Invention
[0002] The present invention relates to a core structure of a gun
trigger lock, and more particularly, to a gun trigger lock
comprising two embedded parts. The main structure comprises a
straight core rod inserted in the core rod hole of one of the
embedded parts. A long keyhole is formed at the open end of the
straight core rod, having an aspheric bump at the bottom of the
keyhole. Moreover, a key shapes a pit corresponding to the bump at
its front end. The key can insert into the long keyhole of the
straight core rod to turn the rod rotating, and then to lock the
two embedded parts by meshing the ratchet wheels, or to release the
two embedded parts by separating the ratchet wheels.
[0003] The present invention comprises a first embedded part and a
second embedded part which can be combined together or release
separately. The two embedded parts can lock the gun trigger and
trigger guard to disable the gun, preventing it from the
mis-shooting of the users. The first embedded part includes a pit
and a straight hole, where a lock piece and a spring are disposed
in the pit. The lock piece, having parallel ratchets formed on one
side, is pushed by the spring and moves upward constantly. A washer
made of rubber or soft material is disposed adjacent to one side of
the first embedded part. Additionally, the second embedded part
includes a core rod hole, and a straight core rod is disposed
therein, which includes a long keyhole at the open end, and an
aspheric bump disposed at the bottom of the keyhole. A gear shaft,
having parallel ratchets on one side is formed extending from the
straight core rod and is inserted into an open groove of a washer,
which is made of rubber or soft material and disposed adjacent to
one side of the second embedded part. Combination of the gear shaft
and the open groove can insert into the straight hole of the first
embedded part. Furthermore, a key also included in the present
invention has an aspheric pit at the front end, corresponding to
the shape of the aspheric bump at the bottom of the keyhole of the
straight core rod in the second embedded part. Thus, by turning the
key to rotate the straight core rod, accompanying with the gear
shaft, the first and second embedded parts can be combined together
or released separately.
[0004] (b) Description of the Prior Art
[0005] In general, the prior art such as Taiwan Patent Number
272628, a lock device of a gun trigger, comprise a fixation socket
and an embedded socket, where a washer socket is disposed on one
side of the fixation socket and another washer is disposed on one
side of the embedded socket, facing the fixation socket. The
features are the fixation socket including a lock core with a
combination rod extending from it. The combination rod includes
ratchets on one side and is disposed in a containing hole of the
embedded socket, where the ratchets can intermesh with the ratchets
on a lock piece of the embedded socket to show lock status, or
separate to show open status.
[0006] Accordingly, as the Taiwan Patent Number 496511, trigger
lock comprised of multiplicity of steel sheet, comprises two
embedded parts which can be interlocked. One of the embedded part
has a lock piece and a spring inside, where the lock piece having
ratchets on one side. The other embedded part has a lock core, a
cylinder and a spring, where the lock core extends to form a gear
shaft at the end, having ratchets on one side. One of the embedded
part has a straight hole, where the gear shaft corresponding to the
straight hole can be inserted into and combined properly. By
meshing or releasing ratchets of the gear shaft and the lock piece,
the gun trigger lock shows lock or open status. The key features
are: the two embedded parts body are packed in a housing with
multiplicity of reinforced plates, which are both made of special
reinforced steel sheet formed by direct stamping. The housing and
multiplicity of reinforced plates are assembled together with other
related components, and then are combined and fixed together by
stamping and riveting, so as to construct the main body of the
embedded parts.
[0007] Additionally, this prior art relates to two embedded parts
which can be intermeshed with each other as in lock position, or be
released separately with each other as in open position by way of
the ratchet structure inside both the gear shaft and lock piece.
The gun trigger and trigger guard can be lock or open by the action
of two embedded parts packed therein. The structure can disable the
gun trigger and prevent from the mis-shooting of the third
party.
[0008] However, the prior arts involve complicated structures and
many components to fabricate the gun trigger lock and much time to
assemble it, which results in high manufacturing cost. Thus, in
order to reduce the procurement cost from the buyer with the
pressure to reduce the street price, the present invention, under
the condition to keep the same performance of the gun trigger lock,
modifies the structure and successfully cost down its manufacturing
cost.
[0009] Furthermore, in some EU or USA area, the gun is
conditionally opened to public and private are capable of owning or
collecting guns or weapons personally. Some gun lovers or
collectors even have hundreds of guns or weapons collections, while
they need hundreds of corresponding gun trigger locks. It is
obvious a trouble to manage so many locks and keys. Therefore, some
gun and weapon collectors hope manufacturers can simply the
management of the corresponding keys and locks, wherein it will
benefit them much if one key only can manage all of their
locks.
SUMMARY OF THE INVENTION
[0010] The primary purpose of the present invention is to improve
and create a new core structure of a gun trigger lock. The primary
object of the invention is to make it easy and convenient to use
and manage the gun trigger lock by modifying the key design with
corresponding bump in the straight core rod, and without disabling
overall functions of the gun trigger lock.
[0011] Another object of the invention is to reduce the
manufacturing cost and selling price of the gun trigger lock by the
simpler core structure than previous arts.
[0012] Reference will now be made in detail to the illustrated
embodiments of the present invention, examples of which are
illustrated in the accompanying drawings. Wherever possible, the
same reference numbers will be used throughout the drawings to
refer to the same or like parts.
[0013] As shown in FIGS. 1 and 2, the present invention of the gun
trigger lock comprises a first embedded part 1 and a second
embedded part 2, which can be both combined together or released
separately. Additionally, the two embedded parts 1, 2 can lock the
gun trigger and trigger guard to disable their functions, and then,
to prevent from the mis-shooting of the third party. The first
embedded part 1 includes a pit 11 and a straight hole 12, where a
lock piece 13 and a spring 14 are disposed in the pit 11. The lock
piece 13, having parallel ratchets 131 formed on one side, is
pushed by the spring 14 and moves upward constantly. A washer 15
made of rubber or soft material is disposed adjacent to one side of
the first embedded part 1.
[0014] The second embedded part 2 includes a core rod hole 21,
where a straight core rod 22 is disposed herein. The straight core
rod 22 includes an arc groove 223 at the edge of the open end,
providing insertion for a block 211 extending from the inner edge
of the core rod hole 21 and limiting the rotation angle of the
straight core rod 22 when inserted in the core rod hole 21.
[0015] The open end of the straight core rod 22 forms a hollow
cylindrical keyhole 221, where an aspheric bump 222 is disposed at
the bottom. A gear shaft 224, extending from the straight core rod
22 and formed as one unity, have parallel ratchets 225 on one side
and is inserted into an open groove 23 of a washer 24, which is
made of rubber or soft material and disposed adjacent to one side
of the second embedded part 2. Combination of the gear shaft 224
and the open groove 23 of the washer 24 can be inserted into the
straight hole 12 of the first embedded part 1.
[0016] Furthermore, a key 3 is also included in the present
invention and has an aspheric pit 31 at the front end,
corresponding to the shape of the aspheric bump 222 at the bottom
of the keyhole 221 of the straight core rod 22 in the second
embedded part 2.
[0017] The key 3 can be inserted into the keyhole 221 of the
straight core rod 22 and the pit 31 of the key 3 matches well with
the bump 222. By turning the key 3, the straight core rod 22 can be
rotated together with the gear shaft 224.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0031] The following descriptions are of exemplary embodiments
only, and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0032] As shown in FIGS. 2 and 3, the gear shaft 224 and the open
groove 23 of the second embedded part 2 can be matched well and
inserted into the straight hole 12 of the first embedded part 1. By
intermeshing the ratchets 225 on one side of the gear shaft 224 in
the second embedded parts 2 and the ratchets 131 on one side of the
lock piece 13, the two embedded parts 1, 2 of the present invention
are locked, as shown in FIG. 2.
[0033] The two embedded parts 1, 2 of the present invention can be
fastened and fixed at two sides of the gun trigger and the trigger
guard, and then clamp the gun trigger and trigger guard there
between, in order to enclose the gun trigger and disable its
functions.
[0034] As shown in FIG. 4 and 5, when the corresponding key 3 was
inserted into the keyhole 221 of the straight core rod 22 in the
second embedded part 2, the pit 31 of the key 3 can match well with
the bump 222 at the bottom of the keyhole 221. While turning the
key 3, the straight core rod 22 can be rotated together with the
gear shaft 224. Furthermore, by separating the ratchets 225 on one
side of the gear shaft 224 in the second embedded parts 2 and the
ratchets 131 on one side of the lock piece 13, the two embedded
parts 1, 2 of the present invention are opened, as shown in FIG.
4.
[0035] Accordingly, as shown in FIGS. 6 to 11, there are several
types of the bumps 222 in the second embedded part 2 and they have
to be in aspheric shapes. Meanwhile, it is apparent that those
shapes in FIGS. 6 to 11 represent, but not limited to, the
modifications and variations. Thus, it is intended that the present
invention covers different shapes of aspheric bumps without
departing from the spirit or scope of the inventions.
[0036] Thus, FIG. 6 illustrates a triangle bump 222a, FIG. 7
illustrates a gear-shaped bump 222b, FIG. 8 illustrates a S-shaped
bump 222c, FIG. 9 illustrates a star-shaped bump 222d, FIG. 10
illustrates an oval-shaped bump 222e, FIG. 11 illustrates an
intercrossed double oval-shaped bump 222f It is certain that there
should be all kinds of pits 31 of the keys 3 to match with all
kinds of shapes of the bump 222 such that both kinds of them can
function well.
[0037] To sum up, the present invention relates to a straight core
rod 22 of a second embedded part 2, having a deep and long keyhole
221 at its open end, where a bump 222 is disposed at the bottom of
the keyhole 221. In general, because the bump 222 is concealed
deeply at the bottom of the key sink 221, the trigger lock is not
easy to be poked open by other tools such as to reach the
burglarproof function. Furthermore, because the bump 222 and the
pits 31 of the key 3 have different kinds of aspheric geometric
shapes, gun collectors can select a group of gun trigger locks with
the same bump 222 so that all the locks and keys can be compatible
with each other. Thus, it will be very easy and convenient for the
gun collectors to use and manage their gun trigger locks.
[0038] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described
above.
[0039] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention.
