Description

FIELD OF THE INVENTION

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

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.
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.
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.
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.
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.
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.

DETAILED DESCRIPTION

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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˜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.
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.
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.
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.
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.
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.
