[Detailed description of the device]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical timepiece in which a decorative body such as a doll is housed inside a door which is opened and closed during the hour.

[0002]

2. Description of the Related Art In general, a mechanical clock has a structure in which an opening / closing door is provided in front of a timepiece body, and the opening / closing door is opened at the hour of the hour so that a decorative body such as a doll stored in the timepiece body appears. And with equipment clocks installed in open spaces,
A lighting device for illuminating the decorative body such as the doll is provided at a position apart from the clock tower of the equipment clock so as to illuminate the entire clock tower. On the other hand, in the current state of the art clockwork clocks for home use, generally no illumination means is provided.

[0003]

Of course, if a domestic mechanical clock is equipped with a lighting means, the commercial value will be improved.
However, it is problematic to directly apply the lighting means for the above-mentioned equipment clock to a domestic mechanical clock. That is, if the lighting equipment is arranged at a position away from the mechanical clock, the lighting equipment becomes large and power consumption becomes large. Further, when the decorative body such as a doll does not completely protrude from the front of the timepiece, the decorative body is not properly illuminated and is difficult to see, and there is a problem that it is not powerful.

Therefore, the present invention has been made for the purpose of providing an illuminating device for a mechanical timepiece, which can reliably illuminate a decorative body such as a doll, and can downsize the illuminating device and consume less power.

[0005]

[Means for Solving the Problems] That is, a mechanical timepiece according to the present invention is a mechanical timepiece in which a decorative body is housed inside a door that is opened and closed at the hour, and the decorative body is illuminated only when the door is opened. Inside the door, a lighting means is provided which is turned on / off in association with the opening / closing operation of the door.

The illuminating means is usually arranged inside the door. For example, when the stage on which the decorative body is arranged is to project forward, it is projected to the front side of the door together with the stage. Is configured as follows.

Further, the on / off mechanism of the illumination means does not have to be directly associated with the operation of the door, and may be configured to be on / off associated with, for example, the above-mentioned protruding operation of the stage. The point is that it should be turned on and off when the door is opened and closed.

[0008]

When the hour arrives, the door in front of the timepiece is opened, the lighting means is turned on, and the ornament is illuminated. Then, after a lapse of a certain period of time, the door is closed, and along with this operation, the illumination means is turned off and the illumination is stopped. Therefore, the lighting means illuminates only around the decorative body for a certain period of time, so that the power consumption can be minimized.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. Figure 1
FIG. 1 is a cross-sectional view showing the mechanical clock 1 of this embodiment.
The center right side is the front. As shown in FIG. 1, an opening 2a is provided on the front surface of the timepiece body 2, and a double-opening door 3 is provided in the opening 2a so as to be opened and closed. A stage 5 on which a doll 4 (decorative body) is placed is disposed behind the door 3, and the periphery of the stage 5 is covered with a box body 6 except for the front side. A support member 7 is attached to the upper part of the box body 6 along the projecting / retracting direction of the stage 5, and the support member 7 is supported by a plurality of rollers 8 so as to be movable back and forth. The roller 8 is supported by a roller case 9, and the roller case 9 is attached to and supported by the timepiece body 2.

At the lower part of the stage 5, there is provided a drive unit 10 for opening and closing the door 3 and moving the stage 5 from the inside of the timepiece body 2 to the front front side through the opening 2a. As shown in FIGS. 1 to 4, the drive unit 10 includes a drive shaft 1 connected to a drive source such as a motor (not shown).
1, a transmission gear 12, a worm wheel 13, a door opening / closing link 14, and the like. The drive shaft 11 is disposed below the central portion of the stage 5 and is rotatably supported by bearings 17 and 18 fixed to a support plate 16.
A worm 11a is formed on the outer circumference of the drive shaft 11 between the bearings 17 and 18, and a guide 19 having spiral teeth is screwed on the inner circumference of the worm 11a.
Are fixed to the lower surface of the stage 5. Therefore, for example, when the drive shaft 11 rotates forward, the worm 11a
The stage 5 is moved forward by the screwing of the guide 19 and the guide 19, and when the drive shaft 11 is rotated in the reverse direction, the stage 5 is retracted.

Further, worm wheels 13 provided on the left and right sides of the stage 5 are engaged with the worms 11a of the drive shaft 11 via transmission gears 12 on the left and right sides, respectively, and the rotary shafts of the worm wheels 13 are rotated. 13a is rotatably supported by the support plate 16 and the timepiece body 2. In addition, the rotary shaft 13 of each worm wheel 13
a is the left and right doors 3 via the door opening / closing links 14, respectively.
Are linked to. Each door opening / closing link 14 has an arm 20.
, 21 and 22, and one end of the arm 20 has a rotary shaft 1
An arm 21 is provided on the back surface of each door 3 so as to project integrally therewith, and an arm 22 is provided between the arms 20 and 21.
Both ends of are connected so as to be rotatable relative to each other. Therefore,
For example, the forward rotation of the drive shaft 11 causes the transmission gear 12 and the worm wheel 13 to rotate as indicated by arrows in FIG. 4, the left and right doors 3 are opened, and the stage 5 is moved forward and forward as described above. On the contrary, the reverse rotation of the drive shaft 11 causes the stage 5 to retract into the timepiece body 2 and the door 3 to close.

Further, a spotlight 24 for illuminating the doll 4 on the stage 5 is attached to the front corner of the ceiling in the box 6 which cannot be seen from the front. The spotlight 24 is connected to a power source (not shown) via a switch 26 mounted on the top of the box 6 and turned on / off by a lever 25. The switch 26 is mounted at a position where the lever 25 engages with the roller case 9 and the switch is turned on immediately before the stage 5 finishes moving forward from the timepiece body 2 to the front. Therefore, the doll 4 is illuminated by the spotlight 24 in a state where the stage 5 is substantially moved to the front of the front, and the power of the illumination can be increased. Further, the illumination is stopped when the stage 5 starts to move backward, and the illumination is performed only when necessary, so that the power consumption can be reduced.

The illumination means is not limited to the above-mentioned spotlight, but an EL plate (electroluminescence lamp) may be used. Since the EL plate is thin and small and consumes little power, it can be easily provided at various places. For example, it may be provided on the stage, the ceiling of the box, or the inner surface of the door to illuminate the doll from multiple directions. Further, it is possible to prevent the shadow from being formed by providing it on the left and right side surfaces when viewed from the front of the box body.

Further, in the above embodiment, the turning on / off of the illumination means 24 is entrusted to the movement of the lever 25 (in other words, the movement of the stage 5), but of course it is turned on by directly relating to the opening / closing operation of the door 3. -It may be configured to be turned off.

[0015]

As described above, according to the present invention, since only the ornamental body is illuminated, the illuminating means can be small, and the ornamental body is illuminated only for a certain period of time such as during performance, so that the power consumption can be small. Further, since the lighting means is turned on / off in conjunction with the movement of the stage and the opening / closing operation of the door, a powerful stage can be provided, and the mechanic clock with commercial value can be obtained.
