Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to a perpetual calendar.

[Conventional technology]

Conventionally, as a puzzle game-like calendar that can be changed arbitrarily to each month's calendar, the required number of pieces are simply arranged in a recess and a transparent lid is fitted over the container. Types with lids that prevent the pieces from falling off are
This is shown in Utility Model Publication No. 43-6430.

[The problem that the idea attempts to solve]

The perpetual calendar described in the prior art has the following defects.

(a) If the lid is removed and the pieces are accidentally dropped on the floor when repositioning them, the pieces tend to scatter on the floor, and it is necessary to rearrange the pieces each time they are dispersed. It's inconvenient.

(b) The pieces are likely to be lost due to the above-mentioned dispersion.

(c) The lid is likely to be damaged by dropping it on the floor.

(d) There is an inconvenience that the calendar itself becomes unusable due to reasons b and c.

(e) The transparent lid gets dirty easily, making it difficult to see the text inside.

The object of the present invention is to provide a new perpetual calendar that eliminates the defects described in (a) to (e) above by eliminating the need for a lid.

[Means to solve the problem]

In order to achieve the above purpose, the perpetual calendar of the present invention has a predetermined number of square pieces, including 7 pieces representing the seven days of the week and 31 pieces representing the numbers 1 to 31.
The surface is provided with a recess 5 formed by consecutively forming a cavity 9 of the size of one piece body 1 on the periphery, and the recess 5 is
A base 6 in which all the pieces 1 are fitted in such a manner that they can be slid freely along the bottom surfaces of the recesses 5 and voids 9.
and protrusions 2, 2'8, 8', 11 and recesses provided on the circumferential wall surface of the block body 1, the circumferential wall surface of the recess 5, and the circumferential wall surface of the cavity 9 so as to be slidably fitted so as not to come off. It has grooves 3, 3'7, 7', and 10.

[Example] The embodiment shown in the figure consists of 49 flat square pieces 1, and seven days of the week are marked on the surfaces of seven of these pieces 1, and numbers 1 to 1 are marked on the same 31 surfaces. The number 31 is written on each piece, and the remaining 11 pieces are left blank, and short protrusions 2 and 2' are written on the top and left sides of the pieces 1, and short grooves 3 and 3 are placed on the bottom and right sides of the pieces. ' are provided at the same position, and the vertical and horizontal lengths are seven times the vertical and horizontal lengths of the top body 1, and the depth is the same as the thickness of the top body 1. The base 6 has a large-sized recess 5 on the front side, and long grooves 7 and 7' are formed on the upper and left side walls of the large-sized recess 5 on the lower and right side walls. Protrusions 8 and 8' are provided respectively, and a small space 9 having a square shape of the same size as the piece body 1 is provided at the lower end of the right side of the large size recess 5 so as to protrude continuously from the recess 5, An auxiliary groove 10 similar to the long grooves 7 and 7' described above is formed on the upper side wall of this space 9, and a long protrusion 8 is formed on the lower side wall.
Auxiliary protrusions 11 similar to 8' are provided, and all of the pieces 1 are arranged in the recess 5, and short protrusions 2, 2', long protrusions 8, 8' and auxiliary protrusions 11 are provided.
The short grooves 3, 3', the long grooves 7, 7', and the auxiliary groove 10 are slidably fitted into each other, so that the frame body 1 can be freely slid in the recess 5 and the empty space 9. Separately from these, a ring-shaped stuffing body 13 is constructed of a hard plastic material with elasticity, and this stuffing body 13 is removably fitted into the space 9.

[Effect]

Since the present invention is as described above, for example, when changing the monthly calendar starting from Sunday shown in FIG. 1 to the monthly calendar starting from Wednesday shown in FIG. Leave the space 9 empty and slide one piece 1 from the recess 5 into this space 9 to create an empty part in the same recess 5, and then slide the piece into this empty part. After completing the rearrangement of the pieces in this way, put the piece in the empty space 9 into the recess 5, and return the filling body 13 to the same empty space 9. All you have to do is insert it.

[Effect of idea]

As described above, the present invention includes a predetermined number of square pieces 1 including 7 pieces representing the seven days of the week and 31 pieces representing numbers 1 to 31, and a space 9 of one size in the piece piece 1 as a periphery. A base 6 having a recess 5 formed in series with the recess 5 on its surface, and in which all the pieces 1 are fitted so as to be freely slidable along the bottom surfaces of the recess 5 and the hollow space 9. , protrusions 2, 2' provided on the peripheral wall surface of the block body 1, the peripheral wall surface of the recess 5, and the peripheral wall surface of the cavity 9 so as to be slidably fitted so as not to come off.
8, 8', 11 and grooves 3, 3' 7, 7', 10
These protrusions 2, 2'8, 8', 11, grooves 4, 3'7, 7', 1
0 does not allow the piece body 1 to come off from the recess 5 and the empty space, and does not require a transparent lid like the conventional example, and does not require the above-mentioned (a) to (e).
This has the excellent effect of completely achieving the intended purpose of providing a new perpetual calendar that eliminates the above defects.
