Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention is related to a structure for fixing a
gun's aiming device, and more particularly, to a structure that is
used to attach an aiming device to a gun. The structure of the
present invention has better fixing capability and is easier to be
detached from a gun or attached thereto.
[0003] 2. Description of Related Art
[0004] Conventional aiming devices, such as laser aiming devices,
can be attached to guns. Light emitted from the aiming devices
helps people to aim a target. The aiming devices need to be
attached to barrels of guns by proper fixing structures.
[0005] Reference is made to FIG. 1. A conventional aiming device 8
is attached to a gun by a fixing structure. The fixing structure 9
includes a fixing base 91, a rotatable disk 2, and a locking bolt
93. The rotatable disk 92 is pivoted at the bottom of the fixing
base 91 and projects from two sides of the fixing base 91. Hence,
one can use his fingers to rotate the rotatable disk 92. The top of
the rotatable disk 92 has two wedge-shaped components 921
projecting therefrom. The locking bolt 93 is disposed inside the
fixing base 91 and can be moved upward or downward. The tops of the
two wedge-shaped components 921 contact a lower end of the locking
bolt 93. In this way, the two wedge-shaped components 921 can be
used to control the locking bolt 93 to move upward or downward.
[0006] The aiming device 8 can be attached to a gun (not shown) by
the two directing tracks 911 formed on the top of the fixing base
91 of the fixing structure 9. Rotating the rotatable disk 92 can
make the locking bolt 93 move to the higher ends of the two
wedge-shaped components 921. In this way, the locking bolt 93 can
be moved upward to a higher position and pushed into corresponding
fixing slots (not shown) of the gun. And the aiming device 8 can be
fixed on the barrel of the gun.
[0007] When the rotatable disk 92 is rotated in the opposite
direction, the locking bolt 93 is moved to the lower ends of the
two wedge-shaped components 921 due to gravity. In this way, the
locking bolt 93 is moved downward to a lower position and departs
from the fixing slots of the gun. Thus, the aiming device 8 can be
detached from the gun.
[0008] However, in the above-mentioned fixing structure 9, the
locking bolt 93 is moved upward by the two wedge-shaped components
921 of the rotatable disk 92 to make the fixing structure 9
attached to the gun. Since there is no fixing mechanism provided
between the two wedge-shaped components 921 and the locking bolt
93, the relative movement occurs easily. Hence, it is difficult to
fix the locking bolt firmly in the fixing slots of the gun and the
aiming device 8 is thus easy to move from the original position.
Especially, when percussion is performed, the recoil of gun is
usually very large and the movement of the aiming device 8 occurs
even more easily.
[0009] Furthermore, when one wants to detach the aiming device 8
from the gun, the locking bolt 93 is moved to the lower position by
gravity. Since the locking bolt 93 may be stuck due to friction
force or other reasons and cannot be moved downward, it is usually
difficult to detach the aiming device 8 from the gun speedily.
[0010] Accordingly, as discussed above, the prior art still has
some drawbacks that could be improved upon. The present invention
aims to resolve the drawbacks of the prior art.
SUMMARY OF THE INVENTION
[0011] An objective of the present invention is to provide a
structure for fixing an aiming device to a gun. The fixing
structure of the present invention has position-fixing blocks and
position-fixing concaves for firmly fixing the locking bolt on two
wedge-shaped components of the rotatable disk. In this way, the
locking bolt can stay in a predetermined position to make the
aiming device firmly attached to the gun.
[0012] In addition, when one needs to detach the aiming device from
the gun, two elastic components of the fixing structure are used to
push the locking bolt downward to the lower position and thus
surely depart the locking bolt from the fixing slot of the gun. In
this way, the aiming device can be detached from the gun
speedily.
[0013] For achieving the objective above, the present invention
provides a structure for fixing an aiming device on a gun. In other
words, the fixing structure is used for attaching the aiming device
to the gun. Therein, the gun has a fixing slot. The fixing
structure includes a fixing base, a rotatable disk, a locking bolt,
and two elastic components. The fixing base is disposed fixedly on
a top of the aiming device and has a containing room. The fixing
base is departably attached to the gun. The rotatable disk is
rotatably disposed at a bottom of the fixing base and has two
wedge-shaped components projecting therefrom. Each of the
wedge-shaped components has a slope. The slope has a higher end and
a lower end. The higher end of the slope has a position-fixing
concave. The locking bolt is disposed within the containing room of
the fixing base and capable of being moved upward or downward
therein. The locking bolt has a lower portion with position-fixing
blocks. The two elastic components are disposed between the fixing
base and the locking bolt.
[0014] Therein, when the rotatable disk is rotated to make the
higher ends of the two wedge-shaped components move to the
underneath of the locking bolt, the two wedge-shaped components
push the locking bolt upward into the fixing slot of the gun and
the position-fixing blocks are placed into the position-fixing
concaves. Moreover, when the rotatable disk is rotated to make the
lower ends of the two wedge-shaped components move to the
underneath of the locking bolt, the locking bolt is pushed downward
to a lower position by the two elastic components and thus departed
from the fixing slot of the gun.
[0015] Numerous additional features, benefits and details of the
present invention are described in the detailed description, which
follows.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0024] Reference is made to FIGS. 2-7, which show a structure for
fixing an aiming device on a gun in accordance with the present
invention. As shown in these figures, a fixing structure 3 is used
for attaching an aiming device 1 to a gun 2. The fixing structure
is located between the aiming device 1 and the gun 2 when
attachment is completed. The fixing structure 3 includes a fixing
base 31, a rotatable disk 32, a locking bolt 33, a first elastic
component 34 and two second elastic components 35. Therein, the
fixing base 31 is fixed on the top of the aiming device 1. A
containing room 311 is formed on the top of the fixing base 31. The
containing room 311 has openings on its top, front end, and rear
end for containing the rotatable disk 32 and the locking bolt 33.
The containing room 311 has a pair of first directing tracks 312
formed at two sides thereof. The fixing base 31 can be attached to
the bottom of the barrel 21 of the gun 2 by using a pair of second
directing tracks 22 corresponding to the first directing tracks 31.
The second directing tracks 22 are formed along the barrel 21.
Hence, the fixing base 31 and the aiming device 1 can be attached
to the gun 2 along the barrel 21.
[0025] The rotatable disk 32 is round and has multiple indentations
321 formed periodically thereon. Due to the indentations 321, one
can rotate the rotatable disk 32 easily. A pivotal component 322,
such as a screw, is passed through the center of the rotatable disk
32 and fixed on the top of the aiming device 1. In this way, the
rotatable disk 32 is disposed rotatably between the bottom of the
fixing base 31 and the top of the aiming device 1. The outer edge
of the rotatable disk 32 projects from two sides of the fixing base
31. Hence, one can rotate the rotatable disk 32 easily. The top of
the rotatable disk 32 has two wedge-shaped components 323
projecting therefrom. The two wedge-shaped components 323 are
disposed oppositely and each of them has a slope 324. The slope has
two ends forming with a higher end 325 and a lower end 326. The
slope 324 is sawtooth-shaped. The first elastic component 34 is a
spring. The first elastic component 34 is slipped on the pivotal
component 322 and located between the aiming device 1 and the
rotatable disk 32. The lower end of the first elastic component 322
is placed on the top of the aiming device 1 and the upper end of
the first elastic component 322 butts against the bottom of the
rotatable disk 32. The elasticity of the first elastic component 34
is used to push the rotatable disk 32 upward so that the two
wedge-shaped components 323 disposed on the top of the rotatable
disk 32 can firmly contact the lower portion of the locking bolt
33.
[0026] The locking bolt 33 is a rectangular parallelepiped
substantially. It is disposed horizontally in the containing room
311 of the fixing base 31. The two ends of the locking bolt 33
connect respectively to two sliding components 331. The containing
room 311 of the fixing base 31 has two sides formed with sliding
slots 313. The sliding components 331 connecting to the two ends of
the locking bolt 33 are disposed within the sliding slots 313 and
can be moved upward or downward therein. In this way, the locking
bolt 33 is disposed within the containing room 311 of the fixing
base 31 and can be moved upward or downward therein.
[0027] Lower portions of the two ends of the locking bolt 33 have
position-fixing blocks 332. The higher ends 325 of the slopes 324
of the two wedge-shaped components 323 have position-fixing
concaves 327 corresponding to the position-fixing blocks 332. When
the rotatable disk 32 are rotated to make the locking bolt 33 move
to the higher ends 325 of the two wedge-shaped components 323, the
position-fixing blocks 332 is used together with the
position-fixing concaves 327 to fix the position of the locking
bolt 33.
[0028] The two second elastic components 35 are springs and
respectively slipped on two poles 333 projecting from the upper
portion of the two ends of the locking bolt 33. The second elastic
components 35 are located between the fixing base 31 and the
locking bolt 33. The lower ends of the second elastic components 35
is placed on the upper portions of the locking bolt 33 while the
upper ends of the second elastic components 35 butt against tops of
depressions 314 formed on the fixing base 31 respectively. The
second elastic components 35 are used to push the locking bolt 33
downward. The two ends of the locking bolt 33 have two gear wheels
334 disposed thereon respectively. The gear wheels 334 mesh with
the sawtooth-shaped slopes 324 of the two wedge-shaped components
323.
[0029] The bottom of the barrel 21 of the gun 2 has fixing slots
23. The fixing slots 23 are formed vertical to the barrel 21. The
aiming device 1 is attached to the barrel 21 of the gun 2 by using
the first directing tracks 312 together with the second directing
tracks 22. When the aiming device 1 is placed to the predetermined
position, one can rotate the rotatable disk 32 to make the locking
bolt 33 move to the higher ends 325 of the two wedge-shaped
components 323. Thus, the locking bolt 33 is moved upward to the
higher position by the two wedge-shaped components 323 and pushed
into the fixing slots 23 of the gun 2. In the meantime, the
position-fixing blocks 332 is also pushed into the position-fixing
concaves 327 to firmly fix the locking bolt 33 and thereby the
aiming device 1 is surely fixed on a predetermined position of the
barrel 21 of the gun 2. In this way, the aiming device 1 can be
attached to the gun 2 speedily.
[0030] When one wants to detach the aiming device 1 from the gun 2,
he only needs to rotate the rotatable disk 23 in the opposite
direction. Rotating the rotatable disk 23 makes the lower ends 326
of the two wedge-shaped components 323 move to the underneath of
the locking bolt 33 and the locking bolt 33 is moved downward to
the lower position by the elasticity of the second elastic
components 35. In this way, the locking bolt 33 is departed from
the fixing slots 23 of the gun 2 and thereby the aiming device 1
can be detached from the gun 2 speedily.
[0031] In the present invention, the locking bolt 33 has the
position-fixing blocks 332 disposed thereon and the higher ends 325
of the slopes 324 of the two wedge-shaped components 323 have the
position-fixing concaves 327 formed thereon. When the rotatable
disk 32 is rotated to make the higher ends 325 of the two
wedge-shaped components 323 move to the underneath of the locking
bolt 33, the position-fixing blocks 332 are pushed into the
position-fixing concaves 327 to prevent the occurrence of relative
movement between the locking bolt 33 and the wedge-shaped
components 323. Thus, the locking bolt 33 is fixed at a
predetermined position firmly. In this way, the locking bolt 33 is
surely fixed on the gun 2 and the movement of the aiming device 1
is avoided when the attachment is completed.
[0032] Moreover, the second elastic components 35 are disposed
between the locking bolt 33 and the fixing base 31. When one wants
to detach the aiming device 1 from the gun 2, he only needs to
rotate the rotatable disk in the opposite direction to make the
lower ends 326 of the two wedge-shaped components 323 move to the
underneath of the locking bolt 33. At this time, the locking bolt
33 is automatically moved downward to the lower position by
elasticity of the second elastic components 35. In this way, the
locking bolt 33 can be departed from the fixing slots 23 of the gun
2 surely and speedily. Thus, the aiming device 1 can be detached
from the gun 2 speedily.
[0033] Although the present invention has been described with
reference to the preferred embodiments thereof, it will be
understood that the invention is not limited to the details
thereof. Various substitutions and modifications have been
suggested in the foregoing description, and others will occur to
those of ordinary skill in the art. Therefore, all such
substitutions and modifications are embraced within the scope of
the invention as defined in the appended claims.
