Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to an improved
structure of laser sight, and particularly to an improved structure
of laser sight integrable with various firearms and enhancing the
sighting performance.
BACKGROUND OF THE INVENTION
[0002] In order to improve the shooting average of firearms, a
sight, such as a laser sight, is installed at the barrel. The beam
from the laser sight will form a tiny light spot on the target. The
point of impact will be surrounding the tiny light spot. Without
too many influences by external factors such as the distance, the
wind resistance, or the terrain, a user can hit the target smoothly
according to the location of the tiny light spot. In particular,
the value of a laser sight is apparent at nights or in the shooting
environments without sufficient light.
[0003] In general, a laser sight includes a block usually formed
integrally with the laser sight or connected with the laser sight
in a form hard to be separated. On the other hand, the barrel of a
firearm will include a pair of grooves corresponding to the block.
When the laser sight is installed to the barrel of the firearm, the
block is wedged in the grooves for preventing shift and loss of aim
of the laser sight caused by the recoil after shooting.
Nonetheless, there are various types of guns. Due to the
differences in the specifications of various firearms, the laser
sight according to the prior art cannot be applied to different
types of guns. Consequently, different guns may need separate laser
sights, leading to inconvenience in usage and an increase in
cost.
[0004] In addition, as described above, external factors will
influence the shooting average. It is thereby required to observe
the distance of the target, the shooting environment, and the
weather condition prior to shooting outdoors. Those external
factors may result in unexpected trajectories and the point of
impact will deviate more from the tiny light spot. Accordingly, it
is required to adjust the location of emitted light of the laser
module at proper times for coinciding with the point of impact.
Nonetheless, the laser module according to the prior art is fixed
inside the laser sight and the location of the emitted light cannot
be adjusted. Thereby, the application is not flexible and the point
of impact tends to be misjudged.
[0005] Moreover, how to enable and disable the laser module is also
a very important subject. For a right-handed user, when he holds
the butt using his right hand and positions for shooting, the
fingers that can be used flexibly are the thumb and the index
finger; when the left hand, as the supporting hand, supports the
bottom of the butt or the barrel, the fingers that can be used
flexibly are the thumb and the index finger, too. If the power
switch of the laser sight is located beyond the accessible range of
the thumbs and the index finders of both hands, the user's action
of enabling or disabling the laser sight will not be fluent.
According to the prior art, a wire is used for extending the power
switch outside the laser sight and disposing the power switch at
the butt. The drawback is that the power switch is located in the
accessible range of the thumb and the index finger. Once the wire
is pulled, the power switch will stop functioning. Besides,
disposal of the power switch at the butt also impede the fluency of
holding the gun and shooting.
[0006] Because the technologies according to the prior art cannot
solve the problem completely, breakthrough and solutions are
required. Consequently, how to improve the convenience, utility,
and economical benefits has become the critical subjects.
[0007] Accordingly, in view of the fact that the laser sights
according to the prior art are unideal, the present invention
provides a laser sight with more convenience, utility, and
economical benefits for promoting the development of the
society.
SUMMARY
[0008] An objective of the present invention is to provide an
improved structure of laser sight, which uses the freely
disassembling property of the block for disposing at positioning
trenches of different locations and thus applicable to a variety of
firearms. Thereby, the drawback that laser sights can be disposed
only at firearms of similar types is improved.
[0009] Another objective of the present invention is to provide an
improved structure of laser sight, which includes an adjuster on
both sides of the laser sight, respectively. By turning the
adjusters for moving the laser module, the location of the beams
emitted from the laser sight is changed. Furthermore, a
displacement detector is used for giving the distance or angle by
which the laser sight has moved.
[0010] Still another objective of the present invention is to
provide an improved structure of laser sight, which includes a
handle on both sides of the laser sight, respectively. The two
handles are connected by a link. By pulling any of the handles, the
link is turned and further activating or deactivating the laser
sight. In addition, because the handles are disposed on both sides
of the laser sight, the present invention is applicable to users
with different dominant hands.
[0011] For achieving the objectives and effects described above,
the present invention discloses an improved structure of laser
sight, which comprises a sight body, a block, and a plurality of
fixing members. The sight body has a clamping track and two
positioning trenches on one side. The two positioning trenches are

is a spacing between the two positioning trenches. The block is
disposed at the positioning trench. The plurality of fixing members
are disposed in the positioning trenches and position the block in
the positioning trench. The block can be disposed to any of the
positioning trenches and, then wedged and matched to a groove of
various types of firearms.
[0012] For achieving the objectives and effects described above,
the present invention further discloses an improved structure of
laser sight, which comprises a sight body, a first adjuster, a
first displacement detector, a second adjuster, and a second
displacement detector. The sight body has a laser module therein.
The first adjuster includes a first knob, a first push member, and
a first elastic member. The first knob is disposed on one side of
the sight body. The first knob has a plurality of scale grooves on
one side. The first push member is disposed inside the sight body.
One end of the first push member is connected with the first knob
while the other end thereof is disposed against the laser module.
The first elastic member corresponds to the first push member and
is disposed on one side of the laser module. The first displacement
detector includes a first elastic base and a first positioning
shaft. The first positioning shaft is dispose on the first elastic
base. One end of the first positioning shaft corresponds to the
plurality of scale grooves of the first knob. The second adjuster
includes a second knob, a second push member, and a second elastic
member. The second knob is disposed on one side of the sight body.
The second knob has a plurality of scale grooves on one side. The
second push member is disposed inside the sight body. One end of
the second push member is connected with the second knob while the
other end thereof is disposed against the laser module. The second
elastic member corresponds to the second push member and is
disposed on one side of the laser module. The second displacement
detector includes a second elastic base and a second positioning
shaft. The second positioning shaft is disposed on the second
elastic base. One end of the second positioning shaft corresponds
to the plurality of scale grooves of the second knob.
[0013] For achieving the objectives and effects described above,
the present invention further discloses an improved structure of
laser sight, which comprises a sight body and a switch. The sight
body has a circuit module therein. The circuit module includes a
circuit board and a conductive member. The circuit board is
connected electrically with a laser module; the conductive member
is connected electrically with the circuit board. The switch
includes at least a handle, a link, a conductive part, and a
unidirectional torque spring. The handle is disposed outside the
sight body. The link is connected with the handle and disposed
pivotally inside the sight body. The conductive part is disposed at
the link and corresponding to the conductive member. The
unidirectional torque spring is disposed at the link and connected
electrically with the circuit board. The conductive part is moved
by the interlocked motion of the handle and the link and hence
contacting the conductive member. Thereby, the circuit to the
circuit board is established.

DETAILED DESCRIPTION
[0026] In order to make the structure and characteristics as well
as the effectiveness of the present invention to be further
understood and recognized, the detailed description of the present
invention is provided as follows along with embodiments and
accompanying figures.
[0027] First, please refer to FIGS. 1A, 1B, and 2, which show
exploded views (1), (2) and a top view of the structure according
to the first embodiment of the present invention. As shown in the
figures, the present embodiment comprises a sight body 10, a block
30, and a plurality of fixing members 35. The sight body 10 has a
clamping track 12 and two positioning trenches 14 on one side. The
two positioning trenches 14 are disposed between two guiders 122 of
the clamping track 12. Besides, there is a spacing 16 between the
two positioning trenches 14 adjustable according to the type of
firearms. The block 30 is disposed at the positioning trench 14.
The plurality of fixing members 35 are fixed and locked in the
positioning trenches 14 and position the block 30 in the
positioning trench 14.
[0028] Please refer to FIG. 3, which shows an internal schematic
diagram according to the first embodiment of the present invention.
As shown in the figure, the clamping track 12 includes two guiders
122 and an elastic device 124. The two guiders 122 are opposing to
each other and disposed on one side of the sight body 10. The
elastic device 124 is disposed inside the sight body 10 and
connected with the two guiders 122. The barrel of a firearm is
loaded between the two guiders 122. The barrel has a groove (not
shown in the figure) corresponding to the block 30. The block 30 is
wedged and matched in the groove. When the barrel is disposed at
the sight body 10, the clamping track 12 and the block 30 provide
the positioning function for preventing shift of the sight body 10
due to the recoil of shooting.
[0029] Please refer to FIG. 4, which shows a schematic diagram of
the sight body assembled with a firearm according to the first
embodiment of the present invention. As shown in the figure, the
present embodiment further comprises a positioning block 18
disposed in the positioning trench 14. The plurality of fixing
members 35 fix and lock the positioning member 18 in the
positioning trench 14 for filling the positioning trench 14. The
positioning block 18 is disposed in the positioning trench 14
different from the one for the block 30. The plurality of fixing
members 35 fix and lock the block 30 and the positioning block 18
in the plurality of positioning trenches 14 in a detachable method.
Thereby, for changing the block 30 to the other positioning trench
14, after releasing the fixing member 35 fixing and locking the
block 30, the block 30 can be separated from the above of the
positioning block 18. Then the same method is applied for releasing
the positioning block 18 in the other positioning trench 14 and
exchanging the positioning trenches 14 for the block 30 and the
positioning block 18. Afterwards, the fixing members 35 are used
for fixing and locking the block 30 and the positioning block 18,
respectively, and completing the exchange. Accordingly, a user can
adjust the disposition of the block 30 to any positioning trench 14
according to the locations of the trenches on a firearm.
Alternatively, two blocks 30 can be disposed in the positioning
trench 14 concurrently so that the sight body 10 can be applicable
to any type of firearm.
[0030] Please refer to FIG. 5, which shows a cross-sectional view
of the structure according to the first embodiment of the present
invention. As shown in the figure, the sight body 10 has a heat
sink 102 therein. The heat sink 102 is connected with a laser
module 20. One end of the heat sink 102 passes through a heat
dissipation tunnel 104 of the sight body 10. One end of the heat
sink 102 is parallel with or lower than a heat dissipation hole 106
of the heat dissipation tunnel 104, so that the heat generated by
the laser module 20 can be conducted to the heat sink 102 and
further dissipated through the heat dissipation hole 106. The heat
dissipation tunnel 104 and the heat dissipation hole 106 can be
located on any side of the sight body 10. According to the present
embodiment, the heat dissipation tunnel 104 and the heat
dissipation hole 106 are disposed on the same side of the block 30.
After the sight body 10 is assembled with a firearm, the heat
dissipation hole 106 can be covered up, and hence avoiding moisture
and foreign matters from entering the sight body 10 via the heat
dissipation hole 106. Besides, the appearance will be pleasing to
the eye.
[0031] Please refer to FIG. 6 and FIG. 7, which show an external
view and an internal view of the structure according to the second
embodiment of the present invention. As shown in the figure, the
present embodiment comprises a sight body 10, a first adjuster 50,
a first displacement detector 55, a second adjuster 60, and a
second displacement detector 65. The sight body 10 has a laser
module 20 therein. The first adjuster 50 includes a first knob 502,
a first push member 504, and a first elastic member 506. The first
knob 502 is disposed on one side of the sight body 10. The first
knob 502 has a plurality of scale grooves 5021 on one side. The
first push member 504 is disposed inside the sight body 10. One end
of the first push member 504 is connected with the first knob 502
while the other end thereof is disposed against the laser module
20. The first elastic member 506 corresponds to the first push
member 504 and is disposed on one side of the laser module 20. The
first displacement detector 55 includes a first elastic base 552
and a first positioning shaft 554. The first positioning shaft 554
is dispose on the first elastic base 552. One end of the first
positioning shaft 554 corresponds to the plurality of scale grooves
5021 of the first knob 502. The second adjuster 60 includes a
second knob 602, a second push member 604, and a second elastic
member 606. The second knob 602 is disposed on one side of the
sight body 10. The second knob 602 has a plurality of scale grooves
6021 on one side. The second push member 604 is disposed inside the
sight body 10. One end of the second push member 604 is connected
with the second knob 602 while the other end thereof is disposed
against the laser module 20. The second elastic member 606
corresponds to the second push member 604 and is disposed on one
side of the laser module 20. The second displacement detector 65
includes a second elastic base 652 and a second positioning shaft.
The second positioning shaft is disposed on the second elastic base
652. One end of the second positioning shaft corresponds to the
plurality of scale grooves 6021 of the second knob 602.
[0032] The first push member 504 of the first adjuster 50 has a
thread segment on the surface. By turning the first knob 502, the
first push member 504 is moved towards the inside or outside of the
sight body 10. If the first push member 504 is move towards to
inside of the sight body 10, the first push member 504 will push
the laser module 20 and make the emitted light of the laser module
20 move. Besides, the first elastic member 506 on one side of the
laser module 20 will be pressed and forming a buffer. On the other
hand, when the first push member 504 is move towards to outside of
the sight body 10, due to the elastic force of the first elastic
member 506, the laser module 20 will move towards the direction of
the first push member 504. The principle by which the second knob
602, the second push member 604, and the second elastic member 606
of the second adjuster 60 move the laser module 20 is the same as
the one described above. Hence, the details will not be described
again.
[0033] The first positioning shaft 554 has a first sphere 5541 at
one end. The first sphere 5541 will contact the scale groove 5021
of the first knob 502 under the elastic force of the first elastic
base 552. When the first knob 502 is turned, because the first
sphere 5541 has a curved surface and bears the rotational force
from the first knob 502, the first sphere 5541 will slide out of
the scale groove 5021 and into another scale groove 5021. In other
words, the laser module 20 moves by one scale. This action will
generate a jump or a sound, which reminds the user of the distance
by which the laser module 20 has traveled. The operating method and
effect of the second displacement detector 65 is the same as those
of the first displacement detector 55. Their difference is only on
the accompanying adjusters. Hence, the details will not be
described again.
[0034] The first adjuster 50 and the second adjuster 60 are
perpendicular to each other. The first adjuster 50 is disposed on
the right side of the laser module 20 and enables the laser module
20 to move in the X direction. The second adjuster 60 is disposed
on the bottom side of the laser module 20 and enables the laser
module 20 to move in the Y direction.
[0035] Please refer again to FIG. 7. The present embodiment further
comprises a correction kit 100 located among the first adjuster 50,
the second adjuster 60, and the laser module 20 and put around the
outer side of the laser module 20. Because the light emitted by the
laser module 20 may have shift, the correction kit 100 disposed on
the outer side of the laser module 20 can adjust the angle in
advance. Consequently, the beam of the laser module 20 can be
emitted at a normal angle.
[0036] Please refer to FIG. 8, FIG. 9, and FIG. 10, which show an
exploded view and functional diagrams (1), (2) of the switch
according to the third embodiment of the present invention. As
shown in the figures, the present embodiment comprises a sight body
10 and a switch 70. The sight body 10 has a circuit module 90
therein. The circuit module 90 includes a circuit board 92 and a
conductive member 94. The circuit board 92 is connected
electrically with a laser module (not shown in the figures); the
conductive member 94 is connected electrically with the circuit
board 92. The switch 70 includes two handles 72, a link 74, a
conductive part 76, and a unidirectional torque spring 78. The two
handles 72 are disposed on both sides of the sight body 10,
respectively. The link 74 is disposed pivotally inside the sight
body 10 with both ends connected with the two handles 72,
respectively. The conductive part 76 is disposed at the link 74 and
corresponding to the conductive member 94. The conductive part 76
and the link 76 can be formed integrally. Alternatively, the
conductive part 76 contacts the link 74 and is disposed at the link
74. The unidirectional torque spring 78 is disposed at the link 74.
One end of the unidirectional torque spring 78 is connected
electrically with the circuit board 92.
[0037] The switch 70 is used for activating or deactivating the
laser module 20. In FIG. 9, the deactivated state is shown. The
link 74 is turned by pushing the handle 72. As shown in FIG. 10,
the two handles 72 are turned downwards by approximately
15.about.60 degrees for driving the conductive part 76 to rotate,
which enables one side of the conductive part 76 to contact the
conductive member 94 and thus shorting the circuit to the circuit
board 92 and activating or deactivating the laser module 20. When
the handles 72 are released, the link 74 will restore the handles
72 to their original positions using the elastic force of the
unidirectional torque spring 78. Meanwhile, the conductive part 76
will rotate in the reverse direction to the original position and
release the contact with the conductive member 94. Thereby,
activation and deactivation of the laser module 20 can be
performed. The conductive member 94 is a positive terminal while
the unidirectional torque spring 78 is a negative terminal. A wire
96 is used for connecting the conductive member 94 and the
unidirectional torque spring 78 to the circuit board 92,
respectively.
[0038] The two handles 72 according to the present embodiment are
disposed on both sides of the sight body 10 and close to the active
range of the user's thumb and index finger. In addition, the two
handles 72 are interlocked with the link 74. The two handles 72 can
be controlled fluently regardless whether the dominant hand is
used. For different types of firearms, the supporting hand can also
control the two handles 72 with ease from the location where it
rests. Accordingly, the fluency in usage is enhanced.
[0039] Please refer again to FIG. 2. The present embodiment can
further comprises an indicator 110 disposed on one side of the
sight body 10 and connected electrically with the circuit board 92.
When the state of the switch 70 is switched, the indicator 110 will
be turned on or off. The preferred location for disposing the
indicator 110 is the rear side of the sight body 10. Because the
rear side is closer to the user, it will be more convenient for
viewing. Besides, the location is hard to be found by a nonuser.
Thereby, the location of the user will be exposed easily.
[0040] Please refer to FIG. 11, which shows a schematic diagram of
the frequency adjuster according to the third embodiment of the
present invention. As shown in the figure, the circuit board 92 is
further connected electrically with a frequency adjuster 80. The
frequency adjuster 80 is disposed on one side of the sight body 10
and connected electrically with the circuit board 92. Then a lid 82
is used for sealing. The lid 82 is screwed to the sight body 10. In
addition, a waterproof washer can be further disposed between the
lid 82 and the sight body 10 for improving water resistance. The
frequency adjuster 80 is used for adjusting the frequency of light
emission of the laser module 20, for example, continuous
illumination or cyclic illumination of 3-second emitting and
2-second not emitting. After selecting the frequency, the laser
module 20 is activated by the switch 70. Thereby, the
practicability and the flexibility in tactical application can be
enhanced.
[0041] To sum up, the laser sight according to the present
invention can be disposed to any positioning trench via the block
and thus applicable to a variety of firearms. In addition, by
adjusting the location of the laser module using the adjusters for
different axes, the emitted light spot of the laser sight can be
modified to coincide with the point of impact and increasing the
shooting average. Then the switch is used for controlling the laser
module, and hence improving the fluency of usage and getting close
to users' operating ranges and usage conditions. Thereby, the
flexibility and shooting accuracy of the laser sight can be
improved.
[0042] Accordingly, the present invention conforms to the legal
requirements owing to its novelty, nonobviousness, and utility.
However, the foregoing description is only embodiments of the
present invention, not used to limit the scope and range of the
present invention. Those equivalent changes or modifications made
according to the shape, structure, feature, or spirit described in
the claims of the present invention are included in the appended
