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.
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.
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.
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.
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.
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 disposed between two guiders of the clamping track. Besides, there 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.
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.
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 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.
