Description

[Detailed description of the invention] [Industrial field of application] This invention relates to an extradimensional scope used as an optical teaching material.

[Conventional technology]

Until now, there have been no optical teaching materials that approximate the extra-dimensional scope of the present invention.

[The problem that the idea aims to solve]

The purpose of the present invention is to attach a plurality of objects to be observed, for example, three objects A, B, and C, which are juxtaposed at regular intervals, with the smooth surface 9 of the prism plate 10 exposed outside the binocular housing 1.
When viewed from a predetermined distance away, the object B placed in the middle disappears and only the two objects A and C on either side are visible, and the uneven surface 8 of the prism plate 10 is exposed to the outside of the binocular housing 1. When you look at an object D installed in front of you from a predetermined distance away, you can see that the object D is divided into right and left parts.
Our goal is to provide a highly interesting extra-dimensional scope that allows you to enjoy mysterious vision.

[Means to solve the problem]

In order to achieve the above object, the extra-dimensional scope of the present invention has the front and rear ends open and a pair of upper and lower shaft supports 3, 4 located at the center position in the left-right direction of the front end opening 2.
It has a binoculars housing 1 in the shape of a flat box that allows one to peer through an object to be observed with both eyes, and a pair of upper and lower central protruding shafts 5a and 6a that are pivotally supported by upper and lower shaft supports 3 and 4 of the binoculars housing 1. A rectangular rotating frame 7 is rotatably supported in the front end opening 2 of the mirror housing 1 so that it can be rotated in reverse by manual operation using central protruding shafts 5a and 6a as fulcrums, and a large number of vertically extending frames are provided on one side. A rotating frame is provided inside the rotating frame 7 in which the triangular protrusion 8a has a prism-shaped uneven surface 8 that continues in a zigzag shape in the left-right direction, and the surface opposite to the uneven surface 8 is formed as a smooth surface 9. 7 and a rectangular prism plate 10 that is fitted so as to be able to rotate integrally with the rectangular prism plate 7.

[Function] The extra-dimensional scope with the above configuration has a prism plate 10
With the smooth surface 9 of the binoculars casing 1 exposed,
When you look at a plurality of objects to be observed, for example, three objects A, B, and C arranged at regular intervals as shown in Fig. 6, from a position separated by a predetermined distance as shown in Fig. 7, object B placed in the middle disappears. Only the two objects A and C on both sides are the 8th object.
It becomes visible as shown in the figure, and the prism plate 10
In an inverted state with the convex and concave surfaces 8 of the binoculars exposed outside the binoculars casing 1 as shown in FIG. 1, when one object D to be observed placed in front of the binoculars is looked into from a position a predetermined distance away as shown in FIG. This object to be observed D is divided into right and left parts.
It will now look like two parts as shown in Figure 0. Such a mysterious vision is caused by the refraction of light by the prism plate 10 as shown in FIG.

〔Example〕

An embodiment of this invention will be described below with reference to the drawings. In the figure, reference numeral 1 designates a binoculars housing 1 that allows viewing objects to be observed with both eyes.This binoculars housing 1 has an open front and back end, and a pair of upper and lower shaft supports 3 and 4 located in the center of the front end opening 2 in the left and right direction. It is made of a flat synthetic resin box with a

Note that the shaft supports 3 and 4 have upper notch tongue pieces 3a,
3b and between the lower cut tongue pieces 4a, 4b, a V
Elastically expandable and contractible C-shaped bearing holes 3c and 4, which are cut out as shown in FIG.
It is formed by c.

7 is a central protruding shaft 5 in the front end opening 2 of the mirror housing 1;
The rotating frame 7 is pivotally supported on the upper shaft support 3 (C-shaped bearing hole 3c) of the binoculars housing 1, and the rotating frame 7 is pivotally supported so that it can be rotated in reverse by manual operation using a and 6a as fulcrums. An upper frame 5 made of synthetic resin having a central protruding shaft 5a, and protruding pins 5b, 5 at both ends of the upper frame 5.
pin holes 6b and 6c inserted into c and the mirror housing 1
A lower frame 6 made of synthetic resin and having a central protruding shaft 6a pivotally supported in the lower shaft support 4 (C-shaped bearing hole 4c)
A reversing operation dial 7a is integrally provided in a portion of the lower frame 6 surrounding the central protruding shaft 6a.

Reference numeral 10 denotes a rectangular prism plate that is fitted into the inner groove 7b of the rotating frame 7 so as to be able to rotate integrally with the rotating frame 7. 8a has a continuous zigzag shape in the left and right direction with a peak angle θ and a valley angle θ′ of approximately 90
It has an uneven surface 8 of a continuous prism type on one side, and the opposite side to the uneven surface 8 is formed as a smooth surface 9, and the plate thickness t shown in FIG.
It is integrally molded from a transparent acrylic resin plate of about 5 mm.

The extra-dimensional scope with the above configuration includes a prism plate 10
With the smooth surface 9 of the binoculars casing 1 exposed,
A plurality of objects, for example three objects A, B, are placed side by side at regular intervals (for example, about 30 cm apart) as shown in Fig. 6.
When you look at C from a certain distance (for example, about 50cm) as shown in Figure 7, object B placed in the middle disappears and only the two objects A and C on either side are visible as shown in Figure 8. In the inverted state, with the convex and concave surfaces 8 of the prism plate 10 exposed outside the binoculars housing 1 as shown in FIG. ) When viewed from a distant position as shown in FIG. 9, the object D to be observed is divided into left and right parts and appears as two parts as shown in FIG. 10. In addition,
The mysterious visual observation shown in Figure 8 is that the prism plate 1
The strange visual observation shown in FIG. 10 is caused by the refraction of light R by the prism plate 10 as shown in FIG. It is caused by action.

[Effect of idea]

The extra-dimensional scope of this invention has a frame-incorporated prism plate 10 as described above pivotably supported in the front end opening 2 of the binoculars housing 1 so that the prism plate 10 can be rotated in reverse. Therefore, the object B placed in the middle disappears, and the two objects A, placed on both sides, disappear.
You can enjoy the mysterious vision of seeing only C as shown in Figure 8, or seeing an object D placed in front divided into right and left parts as shown in Figure 10. It is possible to provide a highly interesting extradimensional scope as an optical teaching material that does not exist in the past.
