Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a concave-convex surface switching mirror that can be switched between a plane mirror, a convex mirror, and a concave mirror.

[Conventional technology]

Conventionally, as the above-mentioned uneven surface switching mirror, there has been disclosed Utility Model Application Publication No. 61-73268 (hereinafter referred to as Conventional Example 1);
Utility Model Application Publication No. 61-46256 (hereinafter referred to as Conventional Example 2)
The technique disclosed in Japanese Utility Model Application Publication No. 54-108054 (hereinafter referred to as conventional example 3) is known.

[The problem that the idea aims to solve]

The uneven surface switching mirror of Conventional Example 1 has a flexible mirror plate loosely fitted into the groove of the frame body, and can be switched between a convex mirror and a concave mirror by pressing both ends of the mirror plate with screws. Because of this structure, switching the mirror plate to a convex or concave surface requires rotating a screw, which poses a problem in that the operation is troublesome.

In addition, in the concavo-convex surface switching mirrors of Conventional Examples 2 and 3, a flexible mirror plate is fitted into the front opening of the casing, and this mirror plate is used to control pressure fluid (air, oil, etc.) against the internal space of the casing. ) is configured to switch to a flat, convex or concave surface by supplying and withdrawing the casing, an actuating device for supplying and withdrawing the pressure fluid is required, and the pressure fluid does not leak into the casing. Since it is necessary to create a space in which to put the device, the structure becomes complicated and expensive.

This idea was devised to solve the above-mentioned conventional problems, and its purpose is to make it possible to switch the flexible mirror plate into three types: plane mirror, convex mirror, and concave mirror by simply rotating the handle. The object of the present invention is to provide a concave-convex surface switching mirror with a simple structure and low product cost.

[Means to solve the problem]

In order to achieve the above object, the uneven surface switching mirror of this invention has handle attachment parts 3 and 4 on both left and right sides, and a pair of upper and lower pivot pins 3a on the handle attachment parts 3 and 4.
Desktop type frame body 1 with protruding parts 3b, 4a, and 4b
and a mirror mounting portion 5b of the handle portions 5a, 6a, which has handle portions 5a, 6a fitted to the handle mounting portions 3, 4 of the frame 1, and mirror mounting portions 5b, 6b at the inner ends of the handle portions. A pair of left and right rotating operation handles 5, 6 having horizontally elongated holes 7, 8 with locking protrusions 7a, 8a that are engaged with the pivot pins 3a, 3b, 4a, 4b on the upper and lower surfaces that are displaced toward the 6b side; , is provided with a flexible mirror plate 9 that closes the opening of the frame whose left and right ends are fixed to the mirror mounting parts 5b and 6b of the rotation operation handles 5 and 6, and this mirror plate 9 is attached to the horizontally long handle. In the normal state where the pivot pins 3a, 3b, 4a, 4b are located at the inner ends of the holes 7, 8, it is extended and held as a plane mirror between the left and right rotation operation handles 5, 6. When the movable operation handles 5, 6 are rotated backwards or forwards, the pivot pins 3a, 3b, 4a, 4b engage with the locking protrusions 7a, 8a of the horizontally elongated holes 7, 8, forming a convex mirror or a concave mirror. It is characterized by being configured to be curved.

[Effect]

The mirror plate 9 is extended and held as a plane mirror between the left and right rotating handles 5 and 6 in a normal state in which the pivot pins 3a, 3b, 4a, and 4b are located at the inner ends of the horizontally elongated handle holes 7 and 8. However, the left and right rotation operation handles 5,
When the mirror 6 is rotated backward or forward, it curves as a convex mirror or a concave mirror, and the latching protrusions 7a, 8a are pulled against the pivot pin 3 by the pulling action of the handle due to the curved mirror plate.
a, 3b, 4a, 4b, handle horizontally oblong hole 7,
By having the outer ends of the mirrors 8 hooked to the pivot pins 3a, 3b, 4a, and 4b, the curved state of the convex mirror or concave mirror is maintained.

〔Example〕

An embodiment of this invention will be described in detail below with reference to the drawings. In the figure, reference numeral 1 denotes a desk-mounted frame with feet 2 that touch the floor.Handle attachment parts 3 and 4 are provided on both left and right sides of the frame 1, and a pair of upper and lower pivots are provided on the handle attachment parts 3 and 4. Support pins 3a, 3b, 4a, 4b are provided in a protruding manner.

Reference numerals 5 and 6 denote a pair of left and right rotation operation handles, and these rotation operation handles 5 and 6 are attached to the handle attachment parts 3 and 4 of the frame 1.
The handles 5a, 6a have handles 5a, 6a that are fitted into the handles, and mirror mounting parts 5b, 6b at the inner ends of the handles. Pins 3a, 3b, 4a,
Laterally elongated holes 7, 8 with locking protrusions 7a, 8a are provided with which the screws 4b engage.

This mirror plate 9 is a flexible plastic mirror plate whose left and right ends are fixed to 6b by fitting projections and holes.
has a size that closes the opening of the frame 1, and pivot pins 3a, 3b, 4a,
4b is positioned as shown in Figure 1, and is extended and held as a plane mirror between the left and right rotating operation handles 5 and 6 as shown in Figure 1. Or when rotating forward, the third
It is curved as a convex mirror as shown by the solid line in the diagram or a concave mirror as shown in the imaginary line in Figure 3, and the latching protrusions 7a, 8a overcome the pivot pins 3a, 3b, 4a, 4b by the handle pulling action due to the curved mirror plate. The outer ends of the horizontally elongated handle holes 7 and 8 are connected to the pivot pins 3a, 3b, 4a,
4b as shown in FIG. 3, the curved state of the convex mirror or concave mirror is maintained.

Note that the reference numeral 10 shown in FIG. 4 is a picture card inserted into the gap 11 between the lower frame part of the frame 1 and the mirror plate 9. 9 can be changed to a plane mirror, a convex mirror, or a concave mirror to allow magic games and the like to be played.
