[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clock with a rotating decoration.

[0002]

2. Description of the Related Art Conventionally, there is known a timepiece with a rotating decoration provided with a rotating decoration which reciprocates. The rotary decoration is mounted on the drive shaft from above, and is frictionally coupled to the drive shaft by the weight of the rotary decoration, and reciprocatingly rotates in conjunction with the movement of the drive shaft by the frictional coupling force. Due to such a coupling system, the rotary ornament moves upwardly of the drive shaft when a force exceeding its own weight acts upward. For this reason, it is necessary to take various measures to prevent the rotary decoration from being damaged when an unexpected external force such as vibration is applied during transportation or the like.

[0003] For example, a storage section is provided separately from a watch main body in a personal box, and a rotating decoration is wrapped and packed. In this case, the user is forced to take out the rotating ornament from the personal box and attach the rotating ornament to the drive shaft of the rotating ornament of the timepiece body for use.

As another example, a rotary ornament is previously mounted on a drive shaft of the rotary ornament in the timepiece body, the top of the rotary ornament is pressed against a rotary ornament holding plate fixed to the timepiece frame, and the lower part of the rotary ornament is pressed. In some cases, a cushioning material made of eperan or polypropylene is inserted so that the rotating decoration does not move in the axial direction. In this case also, the user removes the cushioning material and uses it.

[0005]

However, the first prior art has a problem in that the individual packaging box is provided with a rotating decoration accommodating portion, so that the individual packaging box becomes large and the product becomes expensive accordingly. there were. In addition, the second prior art has a problem in that the cost is increased due to the necessity of the rotary decorative holding plate and the cushioning material. In addition, in each case, there is a disadvantage that the user is burdened.

It is an object of the present invention to provide a timepiece with a rotating decoration that can protect the rotating decoration free of user.

[0007]

In order to achieve the above object, a timepiece with a rotating decoration according to the present invention is provided with a driving mechanism for the rotating decoration below a mounting portion of a clock frame. The drive shaft has a drive shaft that protrudes through the through hole of the mounting portion, and a rotating ornament located above the mounting portion is attached to the protruding end of the drive shaft, and the rotary ornament passes through the through hole. elastic pieces Yes in the provided, the elastic piece, the lower edge engageable with retaining engagement claw hole is formed to project, rotation ornaments
When mounted on the protruding end, the engaging claw is

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 3, a lower part of the timepiece frame 1 is integrally provided with a truncated cone-shaped base 1a having an open bottom, and a flat mounting part 1b is mounted on the upper part of the base. When the timepiece is mounted on the mounting surface, it is formed so as to be parallel to the mounting surface. A circular through hole 1c is opened in the mounting portion 1b, and mounting columns 1d, 1d are formed so as to hang down from a lower portion of the mounting portion 1b. 2 is screwed by a mounting screw (not shown). A drive shaft 2a protrudes from the drive machine body 2 so as to be reciprocally rotatable, and the drive shaft 2a protrudes through a through hole 1c (see FIG. 3).

A rotary decoration 3 is located above the mounting portion 1b. The rotary decoration is mounted on the protruding end 2b of the drive shaft 2a, and is rotatable by driving the drive shaft 2a. The rotating decoration 3 is provided with a plurality (three in this embodiment) of elastic pieces 3a, which penetrate through the through hole 1c from top to bottom. An engaging claw 3b for retaining is formed on the elastic piece 3a so as to protrude outward in the radial direction, and this engaging claw can be engaged with a lower edge portion of the through hole 1c. That is, when the rotary decoration 3 is mounted on the protruding end 2b of the drive shaft 2a, the rotary decoration 3 has a predetermined gap with the mounting portion 1b. The dowel 3b and the lower edge of the through hole 1c are engaged with each other to restrict upward movement, thereby preventing the rotating decoration 3 from coming off the mounting portion 1b.

The upper clock frame 1 is integrally formed with a machine body mounting plate 1e, and machine body mounting claws 1f, 1f are provided on the back surface of the machine body mounting plate. The clock mechanism body 4 is attached to the back of the machine body attachment plate 1e by the machine body attachment claws. Dial 5 on front of machine body mounting plate 1e
, And a thin transparent front cover 6 is located in front of the dial. In the gap between the dial 5 and the front cover 6, there are provided a minute hand 7 and an hour hand 8 driven to rotate by the timepiece mechanical body 4. A watch cover 9 is mounted on the watch frame 1 on the back of the watch mechanical body 4.

A battery holder mounting column 1g protrudes from the mounting portion 1c, and a battery holder 10 is screwed to the mounting column by a mounting screw 11. Battery holder 1
Inside 0, a dry battery 11 as a power source for driving the driving mechanical body 2 of the rotary decoration 3 is mounted. Below the table 1a,
The bottom plate 12 is screwed to the base 1a with screws (not shown), and an opening 12a is provided at a position of the bottom plate 12 facing the battery holder 10, and a battery cover 13 is provided in this opening.
The battery 11 is mounted invisibly from the outside.

Although the mounting portion 1b is formed at the lower portion of the timepiece frame 1 in the present invention, it may be formed at the upper portion of the timepiece frame 1.

[0013]

As described above, according to the present invention, a driving mechanism for a rotary decoration is provided below a mounting portion of a timepiece frame, and the driving machine projects through a through hole of the mounting portion. A shaft, and a rotating ornament located above the mounting portion is attached to the protruding end of the drive shaft, and the rotating ornament is provided with an elastic piece penetrating the through-hole, and the elastic piece has a lower edge of the through-hole. An engaging catch for engagement is formed to protrude, and a rotary ornament is attached to the protruding end.
In this state, the engaging pawl has a predetermined gap from the mounting portion, and the rotating ornament is mounted on the protruding end portion so that the drive shaft can move.
It is possible to perform a loose twist rotation operation in conjunction with
With a simple configuration, it is possible to protect the rotating decoration free of user. Further, since the upward movement of the rotary ornament is regulated by the engaging claws, the design limitation of the rotary ornament of the timepiece frame is relaxed.
