[Detailed description of the invention] A lifespan display board that has a part that indicates the set state and a part that displays the battery life, and a gear that is provided on the lifespan display board to rotate the lifespan display board to the set position. A gear, an indicator wheel that rotates once in conjunction with the clock mechanism of the battery clock in accordance with the battery life period of the battery clock, and rotates a life display plate to a life display position after one revolution, and a recess provided in the indicator wheel. The set lever has a protrusion that engages with the guide wheel to rotate the guide wheel to the set position, and a protrusion provided on the set lever that is pressed by the start button of the battery watch to rotate the set lever in the set position. The purpose of this battery life display device is to enable setting of a reference wheel and a lifespan display plate at the same time by operating the start button of the watch.
To provide a battery life display device having a set lever for a battery watch that is easy to operate and has a simple configuration.

The present invention will be described in detail below based on one embodiment.

Figure 1 is an overall perspective view of the battery life display device of the present invention;
3 is a perspective view showing the state of display operation, and FIG. 4 is a perspective view showing the set state after battery replacement.

In the figure, 1 is a case with approximately triangular protrusions 1a, shafts 1b, and 1C.
This is provided.

Reference numeral 2 denotes a cover, which has a central hole 2a having a notch in its center, and a protrusion 2b at the end for positioning with the watch movement.

3 is a life display board, with a diagonal line part 3a on the front indicating the set state.
A grid portion 3b for displaying the life of the battery and a long notched groove 3C in the circumferential direction are provided, and a protrusion on the back side is inserted into the gear portion 3d and the center hole 2a of the cover 2 to prevent the lifespan display plate 3 from being removed. 3e is provided.

Reference numeral 4 designates a set lever, which engages a gear portion 4a that constantly meshes with the gear portion 3d of the life display plate 3 and a concave portion 5C of the reference wheel 5 to change the reference wheel 5 from the state shown in FIG. 3 to the state shown in FIG. 4. A protrusion 4C that engages with the protrusion 4b and the start button 13 of the watch mover
and are integrally provided in the lever main body 16.

The reference wheel 5 has an engagement hole 5a that can be freely engaged with the protrusion 1a of the case.
A cam 5b and the recessed portion 5C are provided, and the cam 5b is rotatable about the shaft 1b.

Reference numeral 6 denotes a guide lever whose one end is rotatably supported, and the other end is provided with a pin 6a, which can be engaged with the cutout groove 3C of the life display plate 3 by vertical movement of the guide wheel 5. There is.

7 is a clutch pinion, and 8 is a clutch wheel which can rotate in only one direction with the clutch pinion 7.

9 is a transmission wheel, 10 is a gear that transmits rotation from a clock, etc., 1
1 is a coil spring provided so that the reference lever 6 is always pressed against the reference wheel 5, and 12 is a coil spring provided to keep the set lever 4 in return rotation (
This is a spring that acts to rotate the machine (to the left).

13 is a start button of the watch, 14 is a clock mechanism, and 15 is a battery.

A lever main body 16 of the set lever 4 is rotatably supported by a shaft 1c.

The reference wheel 5 rotates once a year, for example, during the life of the battery 15.

Next, the operation of the above embodiment will be explained.

In the state shown in Figure 3 (battery life display state), battery 1
5 is replaced with a new one, and once the start button 13 is operated in the direction of arrow A to drive the clock move, the set lever 4 is set and rotated in the direction of arrow B against the spring 12, and at the same time, the life display plate 3 is also rotated. It rotates in the direction of arrow C by gear parts 3d and 4a.

When the start button 13 is further operated, the protrusion 4b of the set lever 4 engages with the recess 5C of the reference wheel 5 and rotates the reference wheel 5 in the direction of arrow C.
is disengaged from the engagement hole 5a, and the reference wheel 5 is moved to the projection 1a.
The pin 6a of the reference lever 6 also moves upward along the inclined surface of the guide lever 6, and the notch 3 of the life display plate 3 moves upward.
C (Fig. 4).

Next, when the start button 13 is operated in the opposite direction to the arrow A, the clock mechanism 14 is driven.

On the other hand, the set lever 4 is rotated by the spring 12 in the counter-arrow B direction, the life display plate 3 is also rotated in the counter-arrow C direction (clockwise), and finally the set lever 4 and the life display plate 3 are rotated by the pin 6a of the reference lever 6. is stopped from rotating.

This position is the set position. At this time, the engagement between the recess 5C of the reference wheel 5 and the protrusion 4b of the set lever 4 is released, and the reference wheel 5 begins to rotate little by little in the direction of arrow C in conjunction with the movement of the clock mechanism.

Here, the reference wheel 5 and clutch pinion 7 are engaged,
The clutch action is designed to work only in the direction of arrow C of the reference wheel 5.

The reference car 5 is 1 according to the life span of the battery 15 of the battery watch.
The clutch pinion 7, the clutch wheel 8,
The speed is reduced by a transmission wheel 9, a gear 10, etc., and if the service life is, for example, one year, the engagement hole 5a of the reference wheel 5 will engage with the protrusion 1a of the case 1 after one year, and the reference wheel 5 will be connected to the coil spring. 11 moves downward, and the pin 6 of the guide lever 6
a moves downward and disengages from the cutout groove 3c of the life display plate 3, and the life display plate 3 is moved rightward (in the direction of arrow C) by the set lever 4, which is rotated back by the action of the spring 12. The battery 15 rotates in the opposite direction), resulting in a state as shown in FIG. 3, and the lattice portion 3b of the life display plate 3 appears on the front window of the watch to display the life of the battery 15.

Although the set lever of the battery life display device according to the present invention is equipped with a gear part, a protrusion part, and a protrusion part configured as described above, the lever itself can be set by operating the start button of the watch. It can be rotated to set and rotate a lifespan display plate in which a gear engages with a gear part, and a reference wheel in which a concave part engages in a protrusion can be set and rotated, and the lifespan can be displayed by simply operating the start button of the watch. Both the board and guide wheel can be set and rotated at the same time, and not only does it require no special operations, but each operation can be performed integrally with a single lever, which has the advantage of simplifying the configuration and allowing easy and efficient operation. have

Furthermore, since the reference wheel that rotates the life display plate to the life display position is linked to the clock mechanism of the battery clock, the clock mechanism of the battery-powered timepiece can be used as is as a means for moving the guide wheel.
