Description

Scope lens and scope system using same

The present invention relates to sights. More specifically, the present invention relates to an aiming lens and a sighting system using the same, which enables a quick and accurate aiming by reducing the error range caused by the reflecting lens while allowing the shooter to recognize the light point more clearly. will be.

In general, sight is a general term for an optical device attached to a firearm for aiming a target.

The traditional aiming method by the alignment of the scale and the sight line is disadvantageous in that the human body has a large error in vibration or tremor and is disadvantageous for near and rapid aiming and the multi-focus is not possible. Contain.

Therefore, an optical scope has been developed to eliminate the hassle of line alignment and increase accuracy. The optical scope is classified into a prism method and a relay lens method, but both of them use an objective and an alternative lens and a reticle. Allows for target expansion and reticle aiming. However, optical scopes also have errors due to vibration and vibration, and limit the rapid aiming, and optical sights such as dot sights replacing dot reticles with light points have been introduced and are widely used.

1 is a schematic diagram showing a schematic structure of a typical dot site.

As can be seen, a typical dot sight has a cylindrical housing 2 attached to a firearm, a transparent window 4 for sealing one end of the housing 2 facing the target, and a transparent window mounted on one inner side of the housing 2. 4) the light emitting element 6 of a point light source such as an LED emitting light in a specific wavelength band in the direction of the light, and is disposed obliquely between the light emitting element 6 inside the housing 2 and the transparent window 4 to selectively select light of a specific wavelength band. And a reflective lens 8 of constant curvature to reflect.

As a result, the light of the light emitting element 6 is reflected by the reflective lens 8 to be recognized as a high-brightness light spot on the sight of the shooter. Therefore, when the shooter focuses the gaze on the target and overlaps the light spot on the target, even without tunnel vision Aim the target quickly and accurately. For reference, the parallelism of the light spots is adjusted to coincide with the bullet firing axis of the barrel.

However, the general optical collimator using the light spot such as the dot sight has a large error range depending on the precision and inclination of the reflective lens 6.

For example, since the light spot seen through the dot sight as seen above is formed on the reflective lens 8 rather than the actual light emitting device 6, if the curvature or tilt of the reflective lens 8 is not correct, the parallelism of the light spot is not correct. This increases the error between the barrel's bullet shot axis and greatly reduces the reliability of aiming. In addition, the reflective lens 8 of the general dot sight is specially coated to selectively reflect light of a specific wavelength range, even if a slight change such as a difference in refractive index due to the coating film, Due to its nature, it is likely to distort the target or light spot or cause unwanted diffuse reflections.

Therefore, the optical collimator using the light spot requires precise processing and disposition of the reflective lens, which in turn increases the overall process and manufacturing cost.

The present invention is to solve the above problems. In other words, the present invention is applied to all types of optical sights using dot spots as well as dot sights to provide a collimator lens that can more clearly recognize the light spots while reducing the error range caused by the reflective lens.

Furthermore, an object of the present invention is to provide an aiming system that can aim at a target more quickly and accurately in spite of vibration or vibration by using the aiming lens.

In order to achieve the above object, the present invention, the first lens is inserted into the housing of the scope fixed to the firearm is disposed perpendicular to the direction of the sight of the fire; A light emitting device of a point light source mounted on one surface or rear surface of the first lens to emit light of a specific wavelength band; And first and second transparent wirings stacked on one surface or the rear surface of the same first lens as the light emitting device to supply power to the light emitting device.

In this case, the light emitting device is an SMD (Surface Mount Devices) type LED mounted on one surface or the rear surface of the first lens in a chip on glass (COG) method or an organic electric field having a multilayer structure laminated on one surface or the rear surface of the first lens. It is characterized in that one of the light emitting device, wherein the first and second transparent wiring is characterized in that one of indium-tin-oxide (ITO), indium-zink-oxide (IZO) or carbon nanotubes.

In another aspect, the present invention provides a sighting system using the sighting lens, the cylindrical housing is fixed to the gun so that one end toward the target and the other end toward the target; The first lens inserted into the housing to seal one end of the housing and having the light emitting device mounted on the one surface or the rear surface facing the other end of the housing; A transparent window inserted into the housing to seal the other end of the housing; And a second lens disposed vertically between the first lens in the housing and the transparent window in a direction of the line of sight of the grating, and selectively reflecting light of the specific wavelength band in the direction of the grating. Provide a sighting system.

In this case, the second lens is characterized in that the reflective lens.

In addition, the present invention is a sighting system using the sighting lens, the housing fixed to the firearm to provide a lens hole; And the first lens inserted into the lens hole and mounted on the one surface or the rear surface of the lens hole toward the lattice.

The collimator lens according to the present invention supplies power to the light emitting device through the first and second transparent wirings instead of the light emitting device mounted on the outer surface thereof, and thus it is possible to supply a stable power without covering the eyes of the user.

In addition, the collimator lens according to the present invention can replace the inclined reflecting lens which is the main cause of various errors in the conventional optical collimator with the vertical reflecting lens to prevent distortion of the light spot or target as well as diffuse reflection, It shows the advantage of more stable collimation.

Furthermore, since the lens for the collimator according to the present invention can be used for all the collimators using light spots in addition to the optical sight with no magnification such as dot sight, there is a high applicability.

In addition, the dot sight of the scope according to the present invention has the advantage that it is possible to easily and clearly recognize the light spot at all times through the first and second lenses disposed perpendicular to the user's line of sight while preventing diffuse reflection. .

In addition, Bowsight of the scope according to the present invention can directly recognize the light spot without covering the user's eyes through the first lens and the light emitting element mounted therein instead of omitting the pins that obscure the user's eyes, accurate and fast aiming Makes it possible.

EMBODIMENT OF THE INVENTION Hereinafter, one aspect of this invention is looked at in detail with reference to drawings.

Prior to the full description, the present invention provides a scope lens and a scope system using the same, the lens for the scope according to the present invention is applied to all kinds of scopes using optical spots, such as dot sight, non-magnification and other light spots. It is possible. For the sake of convenience, dot sight and bowsite will be described as a few examples of the sighting system to which the sighting lens according to the present invention is applied, but the technical concept of the present invention is not limited thereto. Can be easily understood.

Figure 2 is a schematic diagram showing a dot sight as an example of the sighting system to which the sighting lens according to the present invention is applied.

As can be seen, the dot sight according to the present invention is a cylindrical housing 10 attached to the firearm, the light emitting element 22 is mounted as a collimator lens according to the present invention is to seal the one end of the housing 10 facing the shooting lattice The first lens 20, the transparent window 30 sealing the other end of the housing 10 facing the target, the second lens 40 interposed between the first lens 20 and the transparent window 30 inside the housing 10. ).

In addition, preferably, the first and

second lenses

20 and 40 and the transparent window 30 are all disposed perpendicular to the line of sight of the shooter, and the light emitting device 22 mounted on the first lens 20 is the second. The lens 40 emits light toward a specific wavelength band, and the second lens 40 is characterized in that the reflective lens selectively reflects light of the specific wavelength band.

Looking at each of them in detail as follows.

The housing 10 is a barrel that connects the first and

second lenses

20 and 40 and the transparent window 30 to be described later, or a portion that plays a similar role and represents a cylindrical or similar shape of a synthetic resin or metal. At this time, preferably, the lower end of the housing 10 is equipped with a fixed grill which is detachably coupled to the scale bundle such as a rifle by a rail method, which may be applied to a general technical concept, and thus a separate description is omitted.

The first lens 20 is an eyepiece that seals one end of the housing 10 facing the grate, or a portion that plays a similar role, and has a disc or a similar form of a transparent insulating material such as glass or plastic, and preferably faces a target. A light emitting device 22 such as an LED is mounted on one surface of the first lens 20, and the first and second transparent wires are stacked along a part or all of the corresponding surface, so that the external power source and the external power supply are connected via the housing 10. Connected.

FIG. 3 is a plan view of the first lens 20 that is a collimator lens according to the present invention, and FIG. 4 is a cross-sectional view taken along the line IV-IV of FIG.

As shown, the first lens 20 has a light emitting element 22 such as an LED mounted on one surface of a transparent insulating material such as glass or plastic, and the first and second transparent wirings 24 stacked on a part or all of the surface thereof. Is connected to an external power source through

In this case, the light emitting device 22 is preferably as small as possible so as to emit light of high brightness and do not obstruct the line of sight of the shooting person. For example, SMD (Surface Mount) mounted on the first lens 20 by a chip on glass (COG) method. Devices) emit light of about 650nm, or a multi-layer organic electroluminescent device laminated on the first lens 20 through a semiconductor process emits light of the same wavelength band.

For reference, a semiconductor process refers to a sequential iteration of thin film deposition, photolithography and etching and patterning of thin films by photolithography, and photolithography is a photoresist ( The sequential iteration of the photoresist coating, the exposure of the photoresist using a mask, and the patterning of the photoresist by development using a developer are generically equivalent, which has the same meaning here. In addition, the organic light emitting device is formed by sequentially stacking a hole transport layer, an organic emission layer, and an electron transport layer between an anode electrode layer and a cathode electrode layer. After applying positive and negative voltages to the anode electrode layer and the cathode electrode layer, the multi-layered device emits visible light when the holes of the hole transport layer and the electrons of the electron transport layer form an exciton in the organic light emitting layer and transition from the excited state to the ground state. This is a generic term, and since it is a device and technology that are widely used in the display field, a detailed description thereof will be omitted.

The first and second

transparent wires

24 and 26 connect an external power source and the light emitting device 22 to supply power for emitting light of the light emitting device 22. For example, the first lens 20 may be formed through a semiconductor process. A thin film of indium-tin-oxide (ITO), indium-zink-oxide (IZO), or carbon nanotubes stacked on the substrate is used. At this time, the shape, size, arrangement, etc. of the first and second

transparent wirings

24 and 26 may be free depending on the purpose.

For reference, when the organic light emitting diode is used as the light emitting device 22, one of the first and second

transparent wirings

24 and 26 may be made of the same material as the anode or cathode electrode layer facing the target of the two electrode layers of the organic light emitting diode. One is made of an opaque material.

As a result, the first lens 20 according to the present invention stably supplies power to the light emitting device 22 without obstructing the eyes of the fired fire through the first and second

transparent wires

24 and 26. 22 emits a point light source toward the second lens 40.

2, the transparent window 40 is an objective lens for sealing the other end of the housing 10 facing the target, or a portion of the transparent material such as glass or plastic, or similar shape.

The second lens 40 is disposed between the first lens 20 inside the housing 10 and the transparent window 30 to emit light of a specific wavelength band emitted from the light emitting element 22, for example, about 650 nm light. While reflecting in the direction of 20), other light passes through and allows the shooter to see the target through the first and

second lenses

20 and 40 and the transparent window 30, and is made of transparent material such as glass or plastic. Or a similar form.

In this case, preferably, the second lens 40 uses a reflective lens concave toward the target from the target grid side to diffuse and reflect the light incident from the light emitting element 22 to a certain degree. Despite the mounted light emitting element 22, the light spot can be recognized clearly.

As a result, the shooter of the dot site according to the present invention can aim at the target quickly and accurately without tunnel vision by overlapping the light spot recognized within the gaze with the eyes focused on the target. In this process, since the first and

second lenses

20 and 40 and the transparent window 30 are all disposed perpendicular to the line of sight of the shooting person, the light spots can be easily and clearly recognized at all times, and of course, unnecessary diffuse reflection can be minimized. Can be.

On the other hand, Figure 5 is a perspective view showing a bow sight (bow sight) as another example of the sighting system to which the sighting lens according to the present invention is applied, Figure 6 is a schematic diagram of the bowsite according to the present invention. For convenience, the same reference numerals and the same names are used for the same parts that play the same role as the above-described parts to avoid unnecessary duplication of explanation.

As can be seen, the bowsight according to the invention comprises a housing 10 attached to the firearm and providing a lens hole 12 and a first lens 20 mounted in the lens hole 12.

At this time, the configuration and operation of the first lens 20 is substantially the same as before, but the light emitting element 22 is mounted on the outer surface of the first lens 20 facing the grating and the first and second transparent wirings (FIGS. 24 and 26 of FIG. 4) are also stacked on the surface.

As a result, the bowshot of the bowsite according to the present invention can accurately aim the target by overlapping the light spot recognized within the line of sight with the target focused on the target, and in the process, the first lens 20 has the line of sight of the target. Since it is placed perpendicular to the direction, the gunner can easily and clearly recognize the light spot at all times despite the specificity such as precision, and can minimize unnecessary diffuse reflection.

The above description and drawings are only illustrative of the invention and do not limit the invention. That is, the present invention may be variously modified, but if these modifications fall within the technical spirit of the present invention, it should be included in the scope of the present invention, and the scope of the present invention should be interpreted as claims and equivalents thereof.
