Description

  The present invention relates to a kaleidoscope with increased image diversity.

The kaleidoscope has an optical system that has a polygonal hollow cylinder with a plurality of mirror surfaces on its inner surface, an eyepiece attached to one end, and an object case that contains the object of the image at the other end. This is a structure in which they are arranged on the inside and both ends of a cylindrical outer cylinder as elements, and various geometric objects that are created by reflecting the object and the outside in multiple mirrors when looking inside from the eyepiece It is an optical application apparatus that can observe a simple image (for example, see Non-Patent Document 1). The diversity of images is due to the chance of the combination of objects having various forms and colors, and the images are completely changed. Because of the diversity beyond the scope of this expectation, it is used as a tool for design and design purposes for obtaining visual enjoyment. A conventional kaleidoscope is constructed by fixing a lens barrel, an eyepiece, and an object case to an outer tube, or has a configuration in which only the object case is movable. As the lens barrel, a 3 to 4 square hollow cylinder is often used.
A lens barrel whose inner surface is a mirror surface is typical, but one inner surface of a triangular hollow cylindrical body is not a mirror surface but a transmission surface or a black absorbing surface. A lens barrel having a non-mirror surface that is not a mirror surface is also used. In a lens barrel whose inner surface is all mirrored, an image having a geometric object can be observed in which axial objects positioned in the axial direction of the lens barrel are repeated infinitely on a plane.

On the other hand, in a lens barrel having an inner surface that is not a mirror surface, different images can be observed for each configuration of the lens barrel. As an example, in the case of a triangular hollow cylinder in which one surface is a transmission surface and two mirror surfaces are isosceles with a small included angle, an object installed at the axial end of the lens barrel is 360 at the center of the field of view. A central image that is repeated in a fan shape is observed, and a peripheral image in which the object seen from the transmission surface repeats in a similar fan shape can be observed on the outer side (see, for example, Non-Patent Document 1). Since this lens barrel is a lens barrel in which two mirrors are arranged in a V shape, it is hereinafter referred to as a V-shaped lens barrel.
Actual application 2004-7925. Published by “Kaleidoscope Book”, Japan Kaleidoscope Museum (7-1 Shibuya Mansion, Shibuya-cho, Shibuya-ku, Tokyo, Tel: 03-3463-6916).

If the lens barrel has an inner surface that is not a mirror surface and the surface is a transmission surface, the object that can be observed from the transmission surface is limited to the eyepiece that can clearly see the vicinity of the object in the axial direction and the depth of focus of the naked eye. For this reason, it is limited to the vicinity of the transmission surface of the lens barrel, such as on the periphery of the axial object and on the inner or outer surface of the outer tube that is transparent or only the outer surface is glazed. However, when a pictorial pattern or photographic image drawn on a transparent outer cylinder is used as an object, the conventional kaleidoscope has a fixed mutual positional relationship between the lens barrel and the outer cylinder. I could only observe it. For this reason, the peripheral video is extremely poor in diversity as compared with the central video that is changing all the time, and has been a problem to be improved.
Along with this kaleidoscope, the following secondary issues occurred. In other words, when the position of the axial object and the radial object are greatly different, an observer with a low diopter adjustment ability, such as an elderly person, observes clear images of both objects with only a pre-mounted eyepiece. The problem of being unable to do so occurred.

  In order to solve the above problem, as described in claim 1 of the present invention, in a kaleidoscope using a lens barrel having a transmission surface, the object is observed from an axial object arranged in the longitudinal axis direction and the transmission surface of the lens barrel. In a kaleidoscope for viewing images of radial objects attached or drawn on the inner and outer surfaces of the outer cylinder and their mirror images, a rotation mechanism is provided between the barrel and the outer cylinder to make the angular position of the two variable. By doing so, we made it possible to observe various images.

  The kaleidoscope object uses an object obtained by processing a material such as colored glass into a sharp shape in order to place importance on color and shape. If the kaleidoscope has a structure that can be easily disassembled, it may cause damage to the eyes and skin as a result of error or intentional scattering, and the infant may swallow. In the present invention, a structure that can be easily disassembled, and at the same time, a structure that can overcome the conflicting problem of achieving the above freedom of movement has been invented. As described in claim 2 of the present invention, a double annular rotation mechanism composed of a plug and a socket is used, and an eyepiece and a lens barrel are fixed to the plug that becomes the inner ring, and the insertion plug that becomes the outer ring. By fixing the outer cylinder, slitting it into a strip shape that can be elastically deformed by providing a return projection at the tip of the socket insertion part, and using a rotating mechanism that cannot be disassembled once the plug is inserted into the socket After the final assembly, disassembly was mechanically impossible, and a structure that can prevent the scattering of objects was devised to improve safety.

  A diopter correction adapter that incorporates a diopter correction lens is prepared in advance in order to easily perform diopter correction according to the diopter ability of each observer, and the diopter correction is realized in combination with the eyepiece 4 Devised a method to do. In this adapter, diopter units, which are units of eyeglass lenses, are used as diopter correction lenses, each having 1 to 5 units of positive and negative.

    According to the present invention, a kaleidoscope that increases the diversity of images and ensures safety can be realized.

    Hereinafter, a kaleidoscope according to the present invention will be described in detail with reference to the drawings. 1 to 5 show a kaleidoscope according to the present invention. 1 shows the basic structure, FIG. 2 shows the components, FIG. 3 shows the assembled state, and FIG. 4 shows the completed drawing. FIG. 5 shows the structure of the diopter correction adapter and the attachment part.

FIG. 1 shows the concept of the kaleidoscope of the present invention. The description is described in accordance with a V-shaped lens barrel in which two plane mirrors are combined in a V shape and one surface of a hollow triangular tube is a transmission surface. However, except for the last image example, a lens barrel having another transmission surface can be incorporated. The eyepiece 4 and the V-shaped lens barrel covered with the eyepiece cover 11 are fixed to a plug which is an eyepiece side part of the rotating mechanism 8, and the rotating outer cylinder 6 is fixed to a socket which is an object side part of the rotating mechanism 8. . For this reason, when holding the eyepiece part by hand and turning the rotating outer cylinder 6, the upper diameter of the rotating outer cylinder on which the lens barrel transmission surface 3 of the V-shaped lens barrel 1 is attached to the surface of the rotating outer cylinder 6 is depicted. Since the direction object 6 is inspected, various images can appear and viewed in combination with the corresponding object and the axial object 5. The objects depicted in the figure are simplified for the sake of explanation, but as shown in the lower part of the figure, just by combining the two rotating outer cylinder upper radial direction objects 6 and the two axial objects, Four kinds of images can be made. By increasing the types and number of objects and changing the direction of the lens barrel opening surface, you can enjoy a variety of images.
Since the object to be observed exists in the axial object chamber and in the inner surface of the rotating outer cylinder or in the vicinity of the outer surface, it is difficult to clearly see the two with the naked eye if the distance between the two objects is greatly different. In order to solve this problem, a diopter correction adapter 16 was devised, in which a diopter correction lens 17 suitable for each observer's naked eye condition can be attached to the eyepiece 4 with one touch.

    FIG. 2 shows components of the rotation mechanism 8. The components constituting the rotation mechanism 8 are a reverse protrusion type rotation mechanism socket 13 and a reverse protrusion type rotation mechanism plug 12. The lead 14 with a return protrusion is elastically deformed when fitted to the tip processed into the latter, and the former inner diameter The lead part expands again when it passes through it, and the jaws of the return protrusion are scratched, so that it cannot be disassembled once assembled. With this mechanism, the eyepiece unit and the rotating outer cylinder can be easily rotated, and the danger of being easily disassembled by a small force, impact, or infant and being scattered inside can be prevented. FIG. 3 shows the assembly situation. The eyepiece 4 and the V-shaped lens barrel are bonded and fixed to the lens barrel mounting plate, and the eyepiece tube portion is assembled by bonding and fixing the reverse projection type rotating mechanism plug and the transparent partition plate 9 while ensuring concentricity. The rotating outer cylinder portion is assembled by bonding and fixing the return protrusion type rotating mechanism socket to the rotating outer cylinder 3. An axial object is thrown into the rotating outer cylinder 3. After fine adjustment of each part, the eyepiece tube part is inserted into the rotating outer tube part, and the turning projection is pushed in, so that the process is completed. FIG. 4 shows a completed drawing. The eyepiece cover 11 is attached to the eyepiece tube portion in advance or attached at the end.

  As shown in FIG. 5, the diopter correction lens is fixed to the diopter correction lens frame 19, and the eyepiece cover 11 is simply attached to the eyepiece cover 11 with an adapter lens mounting screw 18, an adapter mounting magnet 20 or an adapter mounting gonu cap 21. A simple operation or one-touch installation.

    In the industry, when designing patterns on the surface of paper, textiles, building materials, etc., this kaleidoscope is used to create and refer to a large number of patterns by selecting and combining axial and radial objects. it can.
