Description

[Detailed explanation of the idea] The present invention relates to a calendar clock.

Conventional calendar watches have disadvantages such as the calendar display being located within the dial of the watch, making the calendar letters small and difficult to read, and lack of interest due to lack of change in shape.

According to the present invention, a calendar display window is provided outside the time display section, a calendar display board is arranged behind the window so as to be slidable in the longitudinal direction, and the calendar is manually fed. To provide a calendar clock whose characters can be enlarged, whose shape can be varied, and which is fun to operate by yourself.

An embodiment of the present invention will be described with reference to the drawings. As shown in the first to third figures, the clock frame body 1 includes:
A time display section 2 is provided at the front of the central portion, and a movement 3 is fixed to the back. A pair of L-shaped guide pieces 4a, 4b and 5 are provided on the back side of the frame 1.
a and 5b are provided facing each other at a predetermined interval. A calendar display plate 6 is mounted so as to be able to slide freely within the guide groove formed by this guide piece. As shown in FIG. 3, the calendar display board 6 is integrally formed with a reinforcing part 6a having a substantially U-shaped cross section and a display part 6b on which calendar display characters 7 are written on the front surface, facing each other at the outer periphery. It is made by being combined. It is desirable that the reinforcing part 6a and the display part 6b be molded from materials with the same properties so that there is no difference in expansion and contraction due to temperature or the like. 8 is a watch latching hole.

A calendar display window 9 is opened close to the front of the calendar display characters 7. In this example, display window 9
is opened in the plate 10 fixed to the upper part of the back surface of the watch frame 1, but it may be extended integrally from the frame.

Next, the lock means provided between the watch frame 1 and the calendar display board 6 will be explained. As shown in FIGS. 2 and 3, on the side surface of the reinforcing portion 6a of the calendar display board 6, there are locking portions 11 corresponding to the intervals between the calendar display characters 7, and in this example, holes are formed in the side wall. It is formed by drilling. A lock lever 12 is swingably supported on the back side of the watch frame 1. That is, the central axis 1 of the lock lever 12
2a has a split groove and a locking claw at the tip,
This shaft is press-fitted into the bearing hole of the frame (as shown in the third figure). As shown in the second figure, a spring piece 12b is integrally provided on the lock lever 12, and the tip of the spring piece comes into contact with a stopper part 1a bent from the frame toward the back, causing the spring piece 12b to bend. condition. For this purpose, the lock lever 12 is biased counterclockwise in FIG. 2 by a spring force. A locking pawl 12c is provided at one end of the lock lever 12, and can be engaged with the locking portion 11 by the spring force of a spring piece 12b. An operating portion 12d is bent at the other end of the lock lever 12, and comes into contact with the stopper side 1c of the notch 1b of the frame 1 to prevent over-pushing.

With such a configuration, the calendar display board 6
To feed, push the operating part 12d of the lock lever 12 to the right in Fig. 2, and it will come into contact with the stopper side 1c,
The locking claw 12c moves back to the left against the spring force of the spring piece 12b and escapes from the locking portion 11. If the watch body is moved downward in this state, the next display character will appear from the display window 9. Therefore, lever operation part 1
If 2d is released, the lock lever 12 will release the spring piece 1.
2b moves counterclockwise, and locking is performed at the correct position where the locking pawl 12c engages with the locking portion 11. At this position, the calendar display characters 7 are positioned correctly within the display window 9.

Note that the display window may be provided below, on the left, or on the right of the time display section. When provided on the left or right, the calendar display board may be lengthened from side to side, and the latching holes may be provided in the frame.

As described above, according to the present invention, the calendar display characters can be enlarged to provide an easy-to-read calendar clock, and since the calendar display position can be provided at any arbitrary position around the time display section, the shape can be varied. Sending the calendar manually makes it feel more familiar and more fun. In addition, the stop position can be held stably and reliably, and the operation to change the display is smooth and easy.
No malfunctions, simple configuration, and low cost.
It has practical effects such as.
