Description

[Detailed Description of the Invention] The present invention relates to a light-reflecting scope vertical used in a target scope such as a rifle scope.

Some target scopes use a light-reflecting type scope lateral that allows the irradiated image to be clearly seen even when used at dawn or dusk. A conventional example of a light-reflecting scope horizontal was as follows. That is, the scope horizontal is constituted by a set of prisms formed by joining the inclined surfaces of two triangular prisms. A glossy surface representing an aiming image is formed on the inclined surface to which the prism assembly is joined by means such as printing. A lamp is installed on the side of the lens barrel, and the light from this lamp is reflected by the glossy surface and reaches the shooter's eye.

However, in such a conventional configuration, since an expensive and heavy set of prisms is used as a radical,
This went against the demands for lower prices and lighter weight rifle scopes. Furthermore, since the prism assembly is heavy, the part that supports the prism assembly receives a strong impact during shooting, resulting in a drawback that the aiming function is easily disrupted. In addition, since the area of the glossy surface is relatively large, there is a drawback that the aim image becomes blurred due to diffuse reflection of light.

In addition, as another conventional structure, there is Utility Model Publication No. 3972 of 1951. This uses a half mirror instead of a set of prisms. However, this configuration has the drawback that the reflected light from the target is attenuated by the half mirror.

The present invention was developed based on these circumstances, and its purpose is to ensure that the aiming point display image is always clearly visible, the light from the target is not attenuated,
Moreover, the objective is to provide an inexpensive, lightweight, and shock-resistant scope tactical.

An embodiment of the present invention will be described below with reference to the drawings. Figure 1 schematically shows the entire riflescope, with an objective lens 2 at one end of the lens barrel 1.
is provided, and an eyepiece lens 3 is provided at the other end. Further, a condensing lens 4 and an erecting lens 5 are provided in the middle part of the lens barrel 1.

A lateral 6 is installed inside the lens barrel 1. The installation position of this lateral 6 substantially coincides with the position where the target image erected by the erecting lens 5 is formed. The lateral 6 has a support ring 7. A threaded portion (not shown) is provided on the outer peripheral surface of this support ring 7.
is formed, and the support ring 7 is fixed by screwing this threaded portion into a threaded portion (not shown) formed on the inner peripheral surface of the lens barrel 1. As shown in FIG. 2, the support ring 7 has a flange 8 on one side.
This collar part 8 has a metal pin 9,
One ends of 10 and 11 are each fixed by means such as soldering. Pin 9 extends vertically;
Its tip 9a is located at the center of the support ring 7. The pins 10 and 11 extend horizontally, and their tips 10a and 11a are spaced apart from the tip of the pin 9. As shown in Figure 3, each pin 9, 10, 11
The tip portions 9a, 10a, 11a are formed in a conical shape, and the tip angle θ is about 90° as shown in FIG. There is a notch 1 at the top of the support ring 7.
2 is formed.

As shown in FIG. 1, a case 13 is attached to the top of the lens barrel 1. A lamp 14 and a battery (not shown) are built into the case 13. The lamp 14 is located almost directly above the pin 9 of the lateral 6 mentioned above. On the peripheral wall of lens barrel 1,
An opening 15 is formed below the lamp 14.

In the above configuration, the reflected light from the target passes through the objective lens 2, the condenser lens 4, the erecting lens 5, the lateral lens 6, and the eyepiece lens 3, and reaches the shooter's eye. The target image is inverted with an objective lens 2, erected with an erecting lens 5, and magnified with an eyepiece 3. At this time, the scope longitudinal 6 does not attenuate the reflected light from the target unlike a half mirror.

The light of the lamp 14 is transmitted through the aperture 1 formed in the lens barrel 1.
5. The pins 9, 10, 11 are reached through the notches 12 formed in the support ring 7, and the pins 9, 1
0 and 11, and further passes through the eyepiece lens 3 and reaches the shooter's eye. In this way, an aiming image as shown in FIG. 4 is displayed. In FIG. 4, the hatched parts of the images of pins 9, 10, and 11 do not reflect the light from the lamp 14 and are displayed as black shadows, and the unhatched parts reflect the light from the lamp 14. This causes the display to shine. The tip 9a of the vertical pin 9 is the fifth
As shown in the figure, it shines by reflecting the light from the lamp 14,
Show center aiming point. Further, other parts of the vertical pin 9 are shaded in black to display a vertical line. Further, the horizontal pins 10 and 11 are illuminated on the upper side and have a black shadow on the lower side to display a horizontal line.

The shooter can aim by looking at the aiming image shown in FIG. 4 and aligning the target image with the central aiming point (indicated by tip 9a). Since the tip 9a that indicates the aiming point is visible, it exhibits an outstanding aiming function especially when shooting at dawn or in the evening. Further, since a vertical line is displayed by the pin 9 and a horizontal line is displayed by the pins 10 and 11, aiming is further facilitated. Furthermore, since the area of the illuminated portion is relatively small, there is little influence from diffused reflection of light, and the aiming image can be clearly seen without becoming blurred.

Note that the present invention is not limited to the above-described embodiments, and various embodiments are possible. For example, the lateral may have only one vertical pin and no horizontal pins. Further, the notch 12 may not be provided.

The position of the lamp 14 may be shifted from the position directly above the pin 9. For example, in Figure 6, lamp 14
is shifted from directly above pin 9 to the eyepiece side. In this case, the tip angle θ of the tip 9a of the pin 9 is formed to be smaller than 90°, so that the light from the lamp 14 can be provided to the eyepiece side.

FIG. 7 shows another form of radical. That is, the lateral 6 may be composed of the support ring 7, the metal foil 20, and the vertical pin 9. The metal foil 20 integrally has an annular portion 20a and an elongated horizontal portion 20b, and the annular portion 20a is the flange portion 8 of the support ring 7.
is glued to. The vertical pin 9 is connected to this metal foil 20
is fixed on top. When the lateral 6 with this configuration is used, the aiming image is displayed as shown in FIG. That is, only the tip 9a of the vertical pin 9 lights up, thereby displaying the aiming point. Also,
The other part of the vertical pin 9 becomes a black shadow to display a vertical line, and the horizontal part 20b of the metal foil 20 displays a horizontal line.

FIG. 9 shows a further embodiment of the radical. The lateral 6 has a support ring 7, a metal foil 30 and a vertical pin 9. The support ring 7 and the vertical pin 9 are of similar construction to that shown in FIG.
The metal foil 30 has an annular portion 30a and a cross-shaped portion 30b.
It has both. The vertical pin 9 is attached to the support ring 7 so as to overlap the lower part of the cross-shaped portion 30b.
Fixed. When using this Ratical 6,
The aiming image is displayed as shown in FIG. That is, the tip 9a of the vertical pin 9 lights up to indicate the central aiming point, and the other parts of the vertical pin 9 and the cross-shaped part 30b of the metal foil 30 display vertical lines and horizontal lines.

In addition, in the above embodiment, the tip of the pin is conical and the light from the lamp is reflected by its surface, but the tip of the pin is made conical and one surface reflects the light from the lamp. Alternatively, only one inclined surface may be formed at the tip of the pin.

The light provided to the pins may be obtained by introducing external natural light instead of a lamp.

Further, the lateral of the present invention can be used not only for rifle scopes but also for other target scopes such as bow scopes.

As explained above, the horizontal of the present invention has a pin fixed to a support ring, and a reflective surface is formed at the tip of the pin. Therefore, the aim point can always be clearly displayed, and the light from the target will not be attenuated. In addition, it is lightweight, simple and inexpensive to construct and manufacture, and is impact resistant.
