Abstract

(57) [Summary] [Purpose] The seven date bars used for desk calendars are
It has a simple structure and can be locked securely, resulting in an inconspicuous appearance. [Structure] 6 date pieces are connected to form a date stick 3,
Each of the seven date bars 3 arranged side by side in the case 7 has a locking pin 1a at each of the four corners of the upper surface thereof, and the three month number indicating plates 4 are inserted through the insertion openings 6 of the case 7 to obtain the date bars. The 7 date bars 3 are securely locked by being brought into contact with the upper surface of 3 and the locking pin 1a.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a locking structure for a desk calendar.

[0002]

[Prior Art]

 Conventionally, as this kind of structure, as shown in FIG. 6, seven date bars (i) are arranged side by side in a case (b), and a day of the week indicator (c) holding three month display plates (d) is inserted and used. Are known (see Japanese Utility Model Laid-Open No. 63-191366).

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional technique, as shown in the cross-sectional view of FIG. 7, when rearranging the calendar monthly, when inserting the finger into the hole on the back of the case to take out the day of the week indicator c, or Due to the momentum when moving, there was a problem that the seven date sticks fell or fell forward.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to employ a simple structure for the date bar so that the date bar can be securely locked without being disengaged. The goal is to provide an easy-to-read desk calendar that is excellent in appearance.

[0005]

[Action]

 The date bar is locked by the locking pin coming into contact with the month display plate. Since the locking pins are provided at equal intervals on each side, the position of the locking pin does not change even if the date piece at the upper end is rotated by 90 °.

[0006]

【Example】

 Examples will be described with reference to the drawings. In FIG. 1 and FIG. 2, for example, rectangular date pieces 1, 2, ..., Which are formed by plastic and have a square top and bottom, are connected to each other, and can be rotated in the connected state or can be inserted and removed freely. There are 5 date pieces 2 each having a cylindrical concave portion b on the bottom surface and a cylindrical convex portion c on the upper surface, a cylindrical concave portion b on the bottom surface, and locking pins 1a at the four corners of the upper surface. As shown in FIG. 2, seven date bars 3 each consisting of six date pieces, which are connected one by one with the date pieces 1 projecting at intervals, are connected in parallel to form a calendar date part.

3 to 4, the month number display plate 4 is formed by cutting a metal plate or a synthetic resin plate having a wall thickness of about 0.5 to 1.0 mm, or by plastic molding. 4 months for the front and back, 3 months for 12 months, and the day of the week are displayed, showing the usage status. As shown in FIG. 4, 3 on the 7 date bars 3 juxtaposed from the front of the case 7. The month display plate 4 is inserted through the upper insertion opening 6 of the case 7. If the month changes, first take out the three month number display plates 4 from the upper outlet 5 of Case 7, rearrange the date bar 3 into the calendar of the current month, and install them side by side. Insert from the insertion port 6.

FIG. 5 is a sectional view of an essential part of FIG. 4 showing a locking structure. It is prevented that the date pin 3 is locked by the rear locking pin 1a contacting the three month number indicating plates 4 contacting the upper surface of the date piece 1 on the upper stage of the date bar 3 and falling forward. It The locking pins 1a are provided so as to project at equal intervals, and their positions do not change even when the date piece 1 is rotated by 90 °. Note that the case 7 in FIG. 5 illustrates the case of wood processing, but it can be easily molded by plastic molding.

[0009]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects.

In the locking structure according to claim 1, the locking pins projecting from the four corners of the upper surface of the date piece are brought into contact with the month display plate to be securely locked, and the operation is easy, and the locking pins are conspicuous. It is also excellent in appearance.
