BACKGROUND OF THE INVENTION
The present invention relates to an infrared laser sighting device for firearms such as rifles, automatic rifles, mechanical short rifles and the like.
[0002]
[Prior art]
A laser sighting device for a small firearm is installed in parallel with a barrel to which a bullet is fired, and is aimed by irradiating a target with a single bright spot. This type of laser sighting device for firearms is compared to the aiming operation of aiming the target with the sight of the firearm and the sight of the weapon, or looking at the scope and aligning the target with the reticle. In addition, while the main body of the firearm is located away from the shooter's eyes, it is aimed at the bright spot irradiated and projected from the sighting device as a target point, so it can be aimed in a short time, especially Useful for emergency shooting.
[0003]
In general, laser sights are often used at relatively short distances due to the ballistic characteristics of the firearms used, and recent laser sights are invisible to the naked eye at night. Therefore, it is required to use the laser beam together with a goggle type night vision device.
[0004]
By the way, in emergency shooting at a short distance, such as in military applications, it is advantageous and safe that the magnitude of the fire power on the shooting side, that is, the energy of the bullets given to the target per unit time is large and advantageous. There is an increasing need for simultaneous aiming and simultaneous fire on the same target with small arms. In the case of performing multiple simultaneous aiming shootings, conventionally, by giving a unique pulse to the luminescent spot of the laser beam that is the target point, the shooter can identify the sighting device of the unique small weapon, I try to recognize my aim point.
[0005]
As is well known, there is a filter that displays a figure on a visible laser pointer. However, the figure in the laser pointer is originally intended for decoration or symbol display such as arrows, etc., to identify multiple laser pointers and to correct the center deviation from a target far away in the background, It is not intended to prevent losing the bright spot of the laser beam. Therefore, characters, dolls, and irregular shapes are drawn as figures on the laser pointer, and since it is visible light, it is not suitable for the sight of military firearms.
[0006]
[Problems to be solved by the invention]
However, the above-described conventional laser sighting device for a small firearm has a problem as described below because a shooter is recognized by applying a pulse to a small bright spot of a laser beam.
[0007]
The first problem is that the target bright spot is very small, from several millimeters to several centimeters, due to the straightness that is a characteristic of the laser, and when using a goggle type night vision device, a small bright spot pulse is visible. It is difficult to recognize due to the poor nature, it is difficult to distinguish the laser sighting pulse individually in emergency shooting at short distances, and it is difficult to identify the sighting device unique to each firearm That is.
[0008]
The second problem is that, as shown in FIG. 8, when the target background object has a discontinuous shape such as the leaves 13 of the plant, the gap between the leaves 13 of the plant is changed by the laser beam every time the small firearm 19 is moved. Since the bright spot 17 appears to blink due to the movement of the bright spot 17 of 11, it is easy to misunderstand the pulse of the bright spot 17 that identifies each infrared laser sight 20, and the shooter has his own infrared laser sight 20 and others. This means that the possibility of missing the original bright spot by misidentifying the infrared laser sighting device 20 increases.
[0009]
A third problem is that, as shown in FIG. 9, the small bright spot 17 of the laser light is a laser beam when an object 18 behind the target 14 is separated from the target 14 when the target 14 is slightly disengaged. This means that the shooter easily loses sight of the bright spot 17 because the bright spot 17 of light appears to decrease rapidly.
[0010]
In such a short-distance emergency shooting, losing or misidentifying the target point of your laser sighting device is the target point for the shooter because the target point deviates from the target due to movement of the target or shooting recoil. The action of recovering is delayed, and there is a problem that becomes a disadvantage factor in emergency close-up shooting.
[0011]
The main object of the present invention is that when an infrared laser sighting device is attached to a small firearm and a goggle type night vision device is attached at night, and the infrared laser sighting device is attached to the firearm, Infrared laser sighting that can prevent the shooter from recovering the target point that deviates from the target due to movement of the target or reaction of the target by delaying or misidentifying the target point of the laser sighting device Is to provide a vessel.
[0012]
[Means for Solving the Problems]
An infrared laser sighting device according to the present invention is an infrared laser sighting device fixed with a fixture in front of a barrel of a small firearm used in combination with a night vision device, and an infrared laser oscillator (2 in FIG. 1) that oscillates an infrared laser. A battery for supplying power to the infrared laser oscillator (4 in FIG. 1), and a controller for controlling the amount of power supplied from the battery so that the voltage applied to the infrared laser oscillator is maintained at an appropriate value (see FIG. 1). 1 of 3), and mounting et al is the output side of the laser light output from the infrared laser oscillator, composed of a diffraction grating or a special shape lenses to diffract or refract the laser light filters (1 in FIG. 1) The laser beam provided and passed through the filter is characterized by projecting an aiming reticle figure onto the target point of the firearm.
[0013]
When applying the present invention to a plurality of firearms, if the reticle pattern of the filter of each firearm has a different shape, the infrared laser sighting device of each firearm can be visually and individually identified. become.
[0014]
In addition, since the reticle figure can have some area on the projection surface to the target, even if the target background object is a discontinuous shape such as a leaf such as a plant or the like, the visual that human beings originally have It is relatively easy to visually recognize the reticle shape with a simple shape recognition capability, and it is difficult to lose sight of the target point of the infrared laser sighting device.
[0015]
In addition, the reticle figure can easily grasp the deviation and direction of the target point from the target from the visual field of the night vision device, even if the target background is at some distance, and immediately correct the target point. be able to.
[0016]

[0017]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0018]
First, FIG. 2 shows the appearance of an embodiment of a firearm 5 to which the present invention is applied, an enlarged barrel 6 and an infrared laser sighting device 7 according to the present invention. The infrared laser sighting device 7 is fixed to the front of the barrel 6 of the firearm 5 by a fixture 8. A filter 1 is provided at the tip of the infrared laser sighting device 7.
[0019]
FIG. 3 shows an exploded view (FIG. 3A) of an embodiment of the infrared laser sighting device 7 according to the present invention, a case 9 in which the infrared laser sighting device 7 is accommodated, and a switch 10 (FIG. 3B). Referring to FIG. 3A, the infrared laser sighting device 7 includes a filter 1, an infrared laser oscillator 2, a controller 3, and a battery 4. The connection of these components is shown in FIG.
[0020]
In FIG. 1, an infrared laser oscillator 2 is an oscillator such as a semiconductor that oscillates an infrared laser, and a battery 4 supplies electric power therefor. The controller 3 controls the amount of power supplied from the battery 4 so that the voltage applied to the infrared laser oscillator 2 is maintained at an appropriate value so that the infrared laser oscillator 2 can oscillate a stable infrared laser. To. The switch 10 is for manually turning on / off the power supply to the infrared laser oscillator 2.
[0021]
The filter 1 is disposed on the output side of the laser beam 11 output from the infrared laser oscillator 2 and is configured by a diffraction grating or a special shape lens that diffracts or refracts the laser beam 11. The laser beam 11 that has passed through the filter 1 projects a reticle figure 12 as illustrated in the front view of FIG. 1 onto the target point of the firearm.
[0022]
The reticle figure is a visually simple shape, as exemplified by the six typical figures in FIG. In addition, it is an artificial shape that hardly exists in nature. Further, the reticle figure projected by the filter 1 is characterized by having a certain extent, unlike the small bright spot of the laser beam 11.
[0023]
Next, the operation of the infrared laser sighting device 7 of the present invention will be described.
[0024]
In the infrared laser sighting device 7, when the sniper operates the switch 10 in FIG. 1 to turn it on, power is supplied from the battery 4 to the controller 3. The electric power supplied to the controller 3 is controlled to a constant electric power and supplied to the infrared laser oscillator 2 to output infrared laser light 11. When the laser beam 11 is incident on the filter 1 immediately after output, a figure is formed by the action of a diffraction grating or a lens included in the filter 1 and a reticle figure 12 is projected onto the projection surface.
[0025]
FIG. 1 shows a situation in which a filter 1 capable of projecting a figure by a diffraction grating converts a laser beam 11 on a projection surface to draw a concentric reticle figure 12. As in this example, the reticle figure 12 projected by the filter 1 has a visually simple shape. Therefore, when another shooter is operating an infrared laser sighting device equipped with a filter 5 that projects a reticle figure of another shape, the shooter is attached to his own infrared laser sighting device 7 using a night-vision device. The reticle figure 12 projected by the filtered filter 1 can be quickly visually identified from other bright spots. Therefore, the target point can be quickly moved with respect to the target.
[0026]
Also, since the projected reticle figure is an artificial shape that is unlikely to exist in nature, as shown in FIG. 5, there is an indefinite shape such as a leaf 13 of a plant and a background with a gap behind the target. However, since the shape recognition ability inherently possessed by humans allows the shooter to easily recognize the reticle shape 12, it is possible to prevent the shooter from losing sight of the target point. At the same time, even after the night vision device temporarily whites out due to the muzzle flame of the small firearm, the shooter can easily recognize the shape of the target point, so that it is easy to aim again for the next shot.
[0027]
Further, when the reticle figure 12 projected by the filter 1 is a concentric circle as in the embodiment of FIG. 1, if the optical axis is adjusted so that the center of the circle is the target point of the firearm, Since the center can be visually recognized quickly using the night vision device, the target point can be quickly moved with respect to the target in the same manner as described above.
[0028]
Further, as shown in FIG. 6, the reticle figure 12 projected by the filter 1 is a concentric circle having a certain diameter of the laser beam 11, so that the reticle figure 12 is slightly deviated from the target 14. Is projected in such a way that it remains on the target 14. Therefore, the shooter can quickly and intuitively recognize the shift amount and the shift direction of the target point from the target 14, so that the target point can be quickly returned to the target 14.
[0029]
Next, another embodiment of the present invention will be described. Although the basic configuration of this embodiment is not different from the above-described embodiment, the exchange of the types of reticle figures that the filter 1 has is facilitated. In FIG. 7, the external appearance of the infrared laser sighting device of a present Example is shown.
[0030]
7A is a perspective view of the infrared laser sighting device, FIG. 7B is a front view, FIG. 7C is a side view, and FIG. 7D is a back view. In this infrared laser sighting device, a filter changer 16 is disposed on the laser beam output side of the infrared laser oscillator. The filter changer 16 has four filters 15 each having a different reticle shape arranged on the circumference of the disk, and rotates around the center of the circumference. The shooter can rotate the filter 15 one by one and quickly select the filter 15 having a reticle shape different from that of the other shooters.
[0031]
As one of the filters 15, a glass plate that does not have a reticle figure and transmits the laser beam 11 as it is can be set. By doing so, the effect of using as a conventional infrared laser sighting device can be expected with respect to the target 14 beyond the medium distance while ensuring the light quantity of the laser beam 11.
[0032]
【The invention's effect】
The first effect of the present invention is that the filter to be mounted can project various types of reticle figures onto the target, so that the shape can be easily recognized and multiple shooters fire the same target at once. This means that each shooter can quickly distinguish and recognize his aim point from the other shooter's aim point.
[0033]
The second effect is that the projected reticle figure can be recognized much more easily than displaying the laser beam as a dot by the shape recognition ability of a human, so that the target background object has many gaps. In the case of a discontinuous shape, for example, even in the case of a leaf such as a plant, it becomes easy to recognize a reticle figure as a target point.
[0034]
The third effect is that the reticle figure has a certain area, and if even a part of it is applied to the target, it is possible to easily and intuitively grasp the deviation amount and the deviation direction of the target point from the target. When the target background object is far away from the target and the target point is deviated from the target, the target point can be easily returned to the target and re-targeted.
[0035]
It should be noted that the present invention is not limited to the above-described embodiments, and it is obvious that the embodiments can be appropriately changed within the scope of the technical idea of the present invention.
