Abstract

(57) [Summary] [Problem] Unlike the scope for rifles, the aiming device for small arms of the present application requires a lightweight, compact design because the user holds the aim with almost one hand and performs aiming. The problem is to develop a device that is easy to use, and if the device is made more compact, the battery must necessarily be smaller, and the life is an important issue. SOLUTION: In order to realize the compact, lightweight and easy-to-use optical aiming device of the present application, the battery is made small, and a dial operation box used for incidence and light control of a light emitting diode, which has been conventionally used, is eliminated, and light control is performed. Automatically adopting a photodiode, and a flat screw plate is provided to penetrate the external light sensing through hole provided at the lower part of the front surface of the device, and the screw plate is rotated halfway in one operation, so that the photodiode The dimming rate is set to 0, and a mechanism is provided in which the battery related to the light emitting diode is not generated.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an optical sighting device used by being fitted to a small firearm.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, many aiming devices have been developed and well known in which a red light focus is used as an aiming point for incident light from a light emitting diode (LED) or the like as an aim of a single-arm scope (rifle scope) for a large firearm such as a rifle.

As disclosed in Japanese Patent Application Laid-Open No. Hei 10-318700, the aiming scope related to the above rifle scope is extremely light, short and compact, compared to the conventional long and heavy rifle scope. Some have been developed with improved convenience.

[0004] Furthermore, an application for a design registration has been filed as a sight sight for handguns and small arms according to the present application, which has been registered as Design Registration No. 1093192.

[0005] As shown and disclosed in the reference diagram showing the state of use of the above-mentioned Design Registration No. 1093192, it is fitted to a substantially central portion of a handgun, and the light projecting target surface of the present application is a right side surface and a left side surface. The special glass part of the figure is illustrated.

[0006] Furthermore, the focus is projected on the above special glass part.

[0007] A battery is used as a light source of a red light-emitting diode on which a focus is projected. However, if the aiming device of the present application is always set to a use state and left for a long period of time, the life of the battery (battery) is reduced. It has to be a problem.

In addition, since the aiming focus needs to adjust the illuminance (brightness) of the aiming light point depending on the place of use, when it is fog in the early morning, at dusk, etc., an operation box for adjusting the illuminance is required.

[0009]

[Problems to be solved by the invention]

 The aiming device for small arms of the present application is different from the scope for rifles, and it is necessary for the user to aim and aim with almost one hand. It is assumed that. Furthermore, when the battery is made compact, the battery must be reduced in size, and the life of the battery has become an important issue.

It is an object of the present invention to minimize the use of electric power which is input only when the handgun of the present application is used.

[0011]

[Means for Solving the Problems]

 In order to realize the compact, lightweight, and easy-to-use optical sighting device of the present invention, the battery is made small, and the dial operation box used for light emitting diode incidence and dimming, which has been conventionally used, is eliminated, and dimming is automatically performed. It is a means of adopting a photodiode which is used for the first time. (Claim 1)

Further, a flat screw plate is provided to penetrate the external light sensing perforation hole provided at the lower part of the front surface of the device, and the screw plate is half-turned in one operation to make the dimming rate of the photodiode zero. The means is a mechanism that does not generate electricity for the battery related to the light emitting diode. (Claim 2)

An embodiment of the present invention will be described below with reference to the accompanying drawings. The device shown in FIG. 1 is an aiming device (1) which is often used by attaching small arms to the upper part of the barrel of a handgun, and a light projecting target lens surface (2) which stands upright at a central portion of the device. A red light focal point (3) is projected at the center of the camera to make an aiming point appear. It is well known that the red light focus (3) uses a light emitting diode (4) powered by a battery, and the same applies to the small arms sighting device (1) of the present invention. The photo diode (5) shown in Fig. 2 and Fig. 3 is used to eliminate the dial operation box used for light emitting diode injection and dimming in order to minimize the use of the battery power. is there.

The above-mentioned photodiode (5) is provided with a perforated hole (6) for sensing external light in the lower part of the front surface of the aiming device (1) of the present invention, and the photodiode (5) is inserted into the perforated hole (6). Insert it. At the center of the through-hole (6), a transverse through-hole (8) into which a flat screw shutter (7) is inserted is formed.

As shown in FIGS. 2 and 3, the screw shutter (7) has a flat plate shape at the center, and a sensing wave from the photodiode (5) is transmitted to the screw shutter (5) as shown in FIG. Since 7) stands upright in a vertical shape, external light is blocked, so that the red light focus (3) by the light emitting diode (4) also disappears, and the power is turned off. Conversely, as shown in FIG. 3, the sensed wave from the photodiode (5) is released by the screw shutter (7) lying on a flat linear surface in a recumbent manner, and thus the red light generated by the light emitting diode (4). The optical focus (3) is projected on the projection target lens surface (2), and the power is turned on. The operation can be performed by a half turn in one operation.

[0016]

[Operation]

 Since this device is a handgun that can be operated with one hand, it must be as lightweight, small, and simple as possible. Therefore, it is possible to reduce the weight of the battery and obtain a long service life, and to perform on / off operation in one operation.
