Description

[Detailed explanation of the idea] This invention relates to a wall clock.

The pendulum was used not as a speed governor for a clock, but to give it an old-fashioned feel.

There is a wall clock that has a so-called pseudo-pendulum.

The means for driving this pseudo-pendulum uses the same driving source as the driving source of the clock itself, and for this reason, the clock part and the pendulum part are connected by a transmission mechanism and are integrally integrated.

Therefore, for example, when repairing the mechanical part of a watch, it is necessary to open the whole clock, and to correct the hands, touch the hands directly from the front side and encircle them, or to correct them from the back side, the entire wall clock has to be repaired. There were inconveniences such as having to remove the camera from the wall and open the back cover.

According to the present invention, the structure is simplified by completely separating the clock part and the pendulum part, and it is easy to manufacture and repair. To provide a wall clock that allows easy adjustment of fingertips even when using the body.

An embodiment of the present invention will be described.

Reference numeral 1 denotes a front frame, on which a watch mechanical body 2 is fixed slightly above the center of the back, a pointer shaft 3 passes through the front frame, and a pointer 4 is attached to the front surface of the front frame.

A pendulum transparent window 5 is opened in the lower part of the front frame 1 and covered with a transparent cover 6.

The front frame 1 is held in the rear case by hinges 8 so as to be openable and closable.

A swing hand holder 9 is fixed inside the rear case 7.

This swing hand holder is provided with a storage chamber 10 in the center thereof into which a watch mechanical body 2 can be fitted.

There is a battery case 12 for a battery 11 which is a driving source of the pendulum in the upper part of the storage chamber, and a thirteenth holding part 14 of the pendulum is provided above the battery case 12.

Further, in the lower part of the storage chamber 10, a swinging rod driving device 15 is disposed. Reference numeral 16 is a pendulum suspended from the lower end of the swinging tool 13.

The swinging rod holder 9 is fixed to the inside of the rear case with screws 17, 17 (second illustration).

The swinging arm holder 14 has supports 18a and 18b extending front and back opposite to each other on the upper part of the swinging arm holder 9,
The central shaft 19 is passed through a central hole provided in the base 13a at the upper end of the central shaft 19, and both ends of the central shaft are pivotally supported by support plates 18a and 18b.

Therefore, the vibrator 13 is held swingably about the central axis 19.

The swing driving device 15 will be explained.

A circuit board 20 is fixed to the lower part of the pendulum holder 9, and a circuit element 21 and a coil 22 are mounted on this board.

A typical circuit pattern (not shown) is connected to the board, forming a pendulum drive circuit.

A permanent magnet 23 is fixed to the lower end of the vibration generator 13, facing the coil 22, and is electromagnetically driven to swing by the current flowing through the coil 22.

24 is a battery that serves as a power source for driving the clock, and 25 is a hand turning knob for adjusting the time.

Since the wall clock of the present invention is constructed as described above, the clock mechanical body 2 is normally stored in the use room 10, and the time display portion and the pendulum portion are integrated.

Since the time is displayed on the watch mechanism body 2, open the front frame 1 from the rear case 7 and move the watch mechanism body 2 to the right side in Figure 1.
Even if the clock moves away from the storage chamber 10, the clock drive battery 24 also moves, so the time can be displayed without any change.

In this open state, the time is corrected using the hand turning knob 25.

Further, the pendulum portion is driven by a separate battery 11 unrelated to the clock mechanical body 2, and the circuit element 21. Driven by a drive circuit consisting of a coil 22 and the like, the magnet 23 reciprocates from side to side in FIG. 1, thereby causing the swinging ball 16 to reciprocate from side to side.

The swing ball 16 can be reciprocated from the front through the transparent cover 6 even when the front frame 1 is open.

As described above, according to the present invention, the clock mechanical body for displaying the time and the driving device for the pendulum are completely separated, and the clock mechanical body is fixed to the front frame which can be opened and closed. ,
Even when using a pack set type mechanical body, it is extremely easy to correct the pointer, and it is easy to repair as only the necessary parts can be removed. Since this is not necessary, it has many effects such as simplifying the configuration.
