Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a hand type timepiece.

[Prior art and its problems] Conventionally, a hand type timepiece has a timepiece movement having a drive mechanism and the like housed in a case, and the drive mechanism portion of the timepiece movement housed in the case indicates hours, minutes, and the like. The hands are attached and rotated to display the time.

In a hand-held timepiece with a watch movement housed in a watch case, the watch movement inevitably becomes thicker because the watch movement is housed in the watch case, so a thin watch with excellent design should be manufactured. However, it has the drawback of being difficult and expensive. On the other hand, as described in, for example, Japanese Patent Laid-Open No. 60-188870, it has been considered to arrange a train wheel mechanism such as a gear in the needle to improve the design. In that case, there is a drawback that not only a large force is required to move the needle, but also gears and the like must be arranged in a well-balanced manner.

[Object of the Invention] The present invention has been made in view of the above circumstances, and an object of the invention is to provide a hand type timepiece having a small number of parts, excellent design, and suitable for thinning. It is in.

[Points of the Invention] In order to achieve the above-mentioned object, the present invention has a structure in which a timepiece mechanism portion for driving a pointer is housed inside the pointer and the timepiece mechanism portion can be kept fixed. It is a summary.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail based on a wall clock with reference to the drawings.

1 to 3 show an embodiment of the present invention,
FIG. 1 is a perspective view of a wall clock mounted on a wall surface, and FIG.
FIG. 3 is an enlarged cross-sectional view of the main part of the wall clock, and FIG. 3 is a front structure part of the main part shown in FIG.

In FIG. 1, reference numeral 1 is a wall-mounted timepiece, and the timepiece 1 is formed by a short hand (hour hand) 2 and a long hand (minute hand) 3 whose outer appearance is a pointer. And the part corresponding to the dial is the wall surface 4
The timepiece 1 further has a timepiece mechanism portion 5 housed in a minute hand 2 as shown in FIGS. 2 and 3.

The timepiece mechanism unit 5 has a train wheel receiving member 5a integrally formed with a train wheel receiving member and a main plate. The train wheel receiving member 5a is a supporting member 6a.
The support member 6 is fixed to the wall surface 4.

As shown in FIG. 3, the train wheel 7, the battery 8, the LSI 9, the crystal oscillator 10, and the stator 1 are arranged in the train wheel receiving member 5a.
1 and a rotor 12 are arranged, and a rotor pinion 13 meshes with an intermediate wheel 14 which is one of the train wheels 7. Also,
The fourth wheel & pinion 16 meshes with the kana 15 of the intermediate wheel 14,
A third wheel & pinion 18 meshes with a pinion 17 of the fourth wheel & pinion 16, and a second wheel & pinion 20 rotatably held coaxially with the fourth wheel & pinion 16 meshes with a pinion 19 of the third wheel & pinion 18. .

The minute wheel shaft 2 for attaching the minute hand 3 to the second wheel 20.
No. 0a is provided in a protruding manner, and an hour wheel 21 is rotatably attached to the center wheel 20 with the minute hand shaft 20a as an axis. In addition, Kana 22 of the second wheel 20 is behind the sun 23
Further, the hour wheel 21 is engaged with and interlocks with the day wheel 23, and the hour hand shaft 21a of the hour wheel 21 is attached with the minute hand 2.

The short hand 2 has a fixed portion 2a fixed to the hour hand shaft 21a, and is formed with a size and a thickness that cover the timepiece mechanism portion 5. An escape hole 2b is provided near the support member 6.

On the other hand, the fixed hand 3a of the long hand 3 is fixed to the minute hand shaft 20a. The long hand 3 is formed to have substantially the same width and thickness as the short hand 2 in design.

Further, the timepiece mechanism portion 5 accommodated in the train wheel receiving member 5a is supported by the supporting member 6 and fixed to the wall surface 4 by the screw 24, and the hands of the short hand 2 and the long hand 3 are fixed and supported by the supporting member 6. Rotate the stable time display.
The fixing means of the support member 6 is not limited to the illustrated structure.

Therefore, in this embodiment, the center wheel & pinion 20 rotates as the rotor 12 rotates, and the hour hand 3 fixed to the center wheel & pinion 20 rotates in the clockwise direction. The rotation of the center wheel & pinion 20 is transmitted to the hour wheel 21, and the hour hand 2 fixed to the hour wheel 21 is rotated clockwise. The timepiece mechanism portion 5 in the minute hand 2 remains in a fixed position.

Although the timepiece mechanism is housed in the hour hand 2 in the above embodiment, the housing may be on the long hand side. Further, by making the timepiece mechanism section 5 a three-hand type, a second hand can be added to the hands.

On the other hand, when a dial is required, it is provided on the wall surface by appropriate means.

The present invention is not limited to the wall clock.

[Effect of the Invention] As described in detail above, the present invention is very simple because the timepiece mechanism is fixedly housed inside the hands as if only the hands are moving independently. It is possible to provide a hand-held timepiece with a unique and thin shape.
