Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a wristwatch with a generator or a self-winding wristwatch that stores energy by the movement of a rotary weight.

[Outline of device]

In this invention, in a wristwatch with a generator or an automatic winding wristwatch, the rotary weight is arranged on the letter side of the main plate and at a position where the dial, date dial, pointer and the like do not overlap in a plane. By transmitting the rotation to the generator or the hoisting wheel train via the transmission wheel train, the weight of the rotary weight can be secured sufficiently large, the movement of the rotary weight can be seen at a glance, and it is thin and has a good design. It was designed to get a good watch.

[Conventional technology]

In a conventional electronic wrist watch with a weight, Figs.
As shown in FIG. 7 and FIG. 7, a fourth wheel 32, a second wheel 33 and the like for attaching the pointer 4 to the back lid side of the main plate 1 are pivotally supported by the wheel train bridge 31 and the transmission wheel bridge 18 is assembled thereon. , The inner ring 14 was fixed here. Then, the rotary weight 11 is fixed to the outer ring 12 that rotates via the ball 15, and the rotation is generated by rotating the power generation rotor 21 by the weight gear 13 and the first transmission wheel 16 that are integrally formed with the outer ring 12. The electric power generated by the stator 22 and the power generation coil 23 was stored in the battery 41.

The structures of conventional generator-equipped wristwatches and self-winding wristwatches are disclosed in Japanese Patent No. 66989 and Japanese Utility Model Publication No. 56-37081.

[Problems to be solved by the device]

However, in the conventional wristwatch with a generator, the rotary weight must be placed avoiding many components such as the battery, barrel, hand movement coil, generator coil, crystal unit, and switching device, so the watch is made large and thick. Without it, there was a problem that a sufficient size of the rotary weight could not be secured.

Further, since the rotary weight is arranged on the back lid side of the main plate, there is a problem that the winding state cannot be confirmed because the motion of the rotary weight cannot be seen when the watch is attached to the wrist.

An object of the present invention is to obtain a wristwatch that is small and thin, and in which the movement of the rotary weight can be seen while the wristwatch is worn on the wrist.

[Means for solving the problem]

In order to solve the above problems, the present invention arranges the rotary weight on the dial side of the main plate, and further, arranges the rotary weight and the dial or date wheel, pointers, etc. in a position where they do not overlap in plane. The rotation of the rotary weight is transmitted to the power generation mechanism and the winding mechanism by a transmission wheel penetrating the main plate.

[Action]

When the wristwatch with a generator or the self-winding wristwatch constructed as described above is attached to the arm, the rotary weight rotates according to the movement of the arm, but the primary moment of the rotary weight is sufficiently large. The rotation angle is large and the rotation is less attenuated.

Then, since this rotation is transmitted to the rotation of the power generation rotor or the winding of the mainspring through the vehicle, efficient energy supplementation can be achieved.

Further, since the rotary weight is in a position not overlapping the dial plate in plan view, the movement of the rotary weight can be confirmed even when the wristwatch is worn on the wrist.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1, FIG. 2 and FIG. 3 show an analog wrist watch in which a battery is charged by a power generation mechanism by rotation of a weight in a first embodiment of the present invention. A power source such as a chargeable / dischargeable battery 41 or a condenser, an integrated circuit 43 for calculating time information and generating a hand movement pulse, a crystal unit 42 as a source oscillation, a switching device 51, etc. are incorporated on the back lid side of the main plate 1. . Integrated circuit 4
The pulse of 3 is sent to the hand movement coil 44, and the hand movement rotor 45 is rotated by the magnetic field generated in the hand movement stator 46, and this rotation is transmitted to the fifth wheel 47, the fourth wheel 32, the second wheel 33, the day wheel 54. , Wheel 3
Rotate 4 etc. and display the time etc. with pointer 4.

The rotary weight 11, the outer ring 12, and the weight gear 13 are integrally fixed, and rotatably assembled to the inner ring 14 via the ball 15. The collar portion 14a of the inner ring is the character printing portion 6a of the character printing portion 6 of the date dial 6. The inner ring setscrew 21 is screwed to the bottom of the bottom plate of the base plate 1.

A date wheel 6 having numbers 1 to 31 printed thereon is rotatably incorporated on the dial side of the main plate 1. The date indicator 6 is moved by the hour wheel 34 via a date indicator driving wheel (not shown) so as to rotate once per 31st a day. Character printing part 6a of this date indicator 6
The outer circumference of is formed smaller than the rotary weight 11, and both are incorporated in a positional relationship such that they do not overlap in a plane.

Next, the dial 2 is fixed on the date indicator 6 with the main plate 1 and the inner ring 14 as a cradle, and the second hand 32 and the second hand 33 are the second hand and the second hand,
Attach the hour hand to the hour wheel 34. Since the radius of gyration of these hands 4 is smaller than the inner diameter of the rotary weight 11, the rotary weight is
11 and the pointer 4 are in a positional relationship where they do not overlap each other in plan view.

The rotary weight 11 is fixed so as to be integrated with the outer ring 12 and the weight gear 13, and the weight gear 13 is formed on the character side of the first transmission wheel 16 which is axially supported by penetrating the main plate 1. Kana 16a meshes with the story. Since the rotary weight 11 has almost the same outer diameter as the main plate 1, the outer diameter of the weight gear 13 integrated with the main plate 1 is also sufficiently larger than the first transmission, so that the speed increasing ratio of both is large. Therefore, the power generation rotor 21 can be rotated at high speed.

In this embodiment, the weight gear 13 is an external gear, but the same speed increasing ratio can be obtained by using an internal gear.

In order to make the timepiece thin, the first transmission pinion 16a is formed at a position where a part of the first transmission pinion 16a overlaps the rotary weight 11 and the outer ring 12 in height in the cross-sectional direction.

A step portion is provided on the outer circumference of the rotary weight 11, and the gap between the step portion and the case 5 is made smaller than the gap between the rotary weight 11 and the glass 3, and the gap between the rotary weight 11 and the main plate 1 is also set. Is it the first message?
Because it is smaller than the gap with 16a, the watch falls,
Even if the rotary weight 11 vibrates due to an impact or the like, the glass 3 and the first transmission pinion 16a are not damaged.

The rotation of the first transmission wheel 16 rotates the power generation rotor 21 via the second transmission wheel 17, and the power generation rotor magnet attached here.
Since 21a rotates in the power generation rotor hole 22a of the power generation stator 22, an electromotive force is generated in the power generation coil 23, and the electromotive force is conducted to the battery 41 via a rectifier circuit (not shown) to charge the battery. be able to.

The battery 41 may be a secondary battery or a large capacity capacitor as long as it can be charged. The power generation coil 23 and the battery 41 are arranged near the outer periphery of the main plate 1 on the back lid side, and a train wheel for hand movement is arranged in the center.

When the analog wristwatch having the above-mentioned structure is viewed from the dial side, the date can be seen from the hands and the window of the dial at the center, and the rotating weight can be seen to rotate around the date. Since the rotary weight 11 increases the primary moment, the opening angle is 90 degrees or more 180
Since it is made up of less than 10 degrees, a decorative plate made of a material with a light specific gravity is attached to a part without a rotating weight to display various indications, and various dolls and models are attached to make a new design timepiece. Is also possible.

FIG. 4 is a second embodiment of the analog wristwatch according to the present invention, showing an automatic wristwatch using a mainspring.

Similar to the first embodiment, the rotary weight 11 is installed on the dial side of the main plate 1, and the rotation thereof is transmitted to the first transmission wheel 16 pivotally supported on the main plate 1 by the weight gear 13. In the first transmission car 16,
The first idler wheel 62 rotatably incorporated in the idler seat 61 meshes with the movement of the idler seat 61 to rotate the round hole wheel 64 in one direction either directly or via the second idler wheel 63.
The round hole wheel 64 rotates the square hole wheel 65 to wind up the mainspring (not shown) in the barrel 66. The barrel 66 is the third wheel 55, the fourth wheel 3
2 etc. are rotated and the time and the like are displayed on the hands 4 by the action of other escapement mechanism and speed control mechanism (neither is shown).

Although the pointer 4 and the rotary weight 11 do not overlap each other in plan view in this embodiment, a part of the pointer does not overlap with the rotary weight 11.
It is also possible to have a structure that passes between the glass and the glass 3.

[Effect of device]

Since the present invention is configured as described above,
The following effects are achieved.

Since the rotary weight is arranged on the outer peripheral portion of the main plate on the dial side, the weight and the first moment of the rotary weight contributing to the power generation performance and the winding performance can be sufficiently large, so that a small and thin wristwatch can be obtained.

Also, since the rotary weight and the dial, date wheel, day wheel, hands, etc. do not overlap in a plane, the movement of the rotary weight can be seen even when it is attached to the arm, and the motion state and power generation or winding You can check the status. Furthermore, the movement of the rotary weight is transmitted to the train wheel on the back lid side by a transmission wheel that penetrates the main plate, and the power generation mechanism, power supply, hoisting mechanism, barrel, etc. are arranged on the outer periphery of the main plate, so the hand wheel train, The watch can be made thin without overlapping with the switching mechanism or the electronic circuit. Further, since the inner ring of the rotary weight is fixed to the main plate side of the character printing portion of the date indicator, increase in thickness of this portion is also suppressed. And
Since the gap between the rotary weight and the case or the ground plate is smaller than the gap between the rotary weight and the glass or the gap between the rotary weight and the transmission wheel, the glass and the transmission wheel are not damaged at the time of impact.
