Description

[Detailed description of the invention] [Industrial application field] This invention relates to a structure for preventing malfunction of the button part of a waterproof watch used under severe conditions such as swimming and diving where high water pressure and impact are applied.

[Summary of the idea]

This invention has a structure for preventing malfunction of the button part of a waterproof watch, in which a screw ring is engaged with a screw provided on the outer periphery of the outer end of the button pipe constituting the button part and moves back and forth on the outer periphery of the pipe. is interposed between the button pipe and the button to regulate the movement of the button and prevent the button from malfunctioning.

[Conventional technology]

Conventionally, as shown in FIG. 2, buttons used under severe conditions such as high water pressure and impact during swimming and diving have a spring 9 interposed between the button 4 and the button pipe 3, and the spring 9 is Abnormal external forces such as water pressure and impact applied to button 4 due to repulsive force,
A button malfunction prevention structure that prevents the signal from being transmitted to the button 4 has been known.

There was also known a structure in which a screw ring was screwed onto the button pipe to prevent the button from malfunctioning (Japanese Utility Model Publication No. 59-35826).

[Problem that the invention attempts to solve]

However, in the conventional malfunction prevention structure using a spring, only predicted external forces such as water pressure and impact force corresponding to the repulsive force of the spring 9 act on the button 4; water pressure exceeding the repulsive force of the spring 9 Impact force and the like have no effect, and the button is pushed in by external force. Furthermore, if an attempt is made to increase the repulsive force of the spring 9 to prevent the button 4 from being pushed in against external force, the opposite effect occurs in that the button 4 cannot be pressed with a fingertip, resulting in disadvantages such as the button 4 not operating smoothly. Ta.

Furthermore, those using a threaded ring require a flange member to prevent slipping off and a coil spring for engagement, resulting in problems such as an increase in the number of parts and the durability of the coil spring.

The object of the present invention is to provide a button structure for a waterproof watch that overcomes the various problems mentioned above.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention has been developed to provide a button structure that is subjected to high water pressure and impact during swimming and diving, etc., in which the button is connected to a pipe that has a threaded portion on the outer periphery of the outer end of the button pipe, and the button engages with the thread. The button pipe is attached to the button pipe with a waterproof gasket through a threaded ring, and is fixed from the inside of the body with a button retaining ring, and the movable position of the threaded ring prevents the button from malfunctioning. did.

[Effect]

In the button configured as described above, by moving the screw ring toward the outer end of the button, the original pushing stroke of the button is reduced to "0",
It eliminates malfunctions caused by pressing the button due to high water pressure or impact, and creates a completely locked state.

〔Example〕

Examples of this invention will be described below based on the drawings.

In FIG. 1, a threaded ring 6 is attached to the outer peripheral threaded portion 3a of the button pipe 3 fixed to the case.
The button 4 with the waterproof packing 5 attached is assembled into the button pipe 3 via a screw ring 6, and fixed to the end of the button 4 with a button retaining ring 7. The screw ring 6 further has a convex portion 6 on the inner diameter of the ring.
a is provided to regulate the stroke of the button 4. To lock the button 4, rotate the screw ring, position the screw ring 6 outward as shown by the line, and lock the button 4.

In FIG. 3, a rubber ring 10 is fixed to the outer periphery of the screw ring 6 in order to make it easier to turn it.

In the embodiment described above, when the button 4 moves by the button stroke amount b of the screw ring 6 (state 6a), the button stroke amount b becomes "0", and the button 4 can be operated by high water pressure or impact. This allows the structure to be used as a lock device.

[Effect of idea]

As explained above, this invention adopts a threaded ring as a part of the button part, and forms an inward protrusion near the boundary between the threaded part and the non-threaded part on the inner periphery, so that the part We were able to suppress the increase in points, do not use parts with durability problems such as coil springs, and create a button lock mechanism that is easy to disassemble and repair. Therefore, it is easy to create a high-pressure waterproof watch that can be used safely even under conditions of high water pressure and impact, such as when swimming or diving.

Claims (1)

[Scope of Claim for Utility Model Registration] A button pipe with a screw formed on the outer periphery and consisting of a tip part protruding from the body and a rear end part fixed to the body, a head part protruding to the outside, and the interior of the button pipe. A button consisting of a shaft part that is slidably attached through waterproof packing, a tip part with an inner periphery loosely surrounding the head of the button, and a screw that engages with a screw formed in the button pipe. A button structure for a waterproof watch, comprising: a screw ring having a rear end portion on the inner periphery; The button of the waterproof watch is characterized in that when the button is locked, the side surface of the tip of the convex portion comes into contact with the back of the head of the button, and when the button is not locked, the side surface of the tip of the button pipe comes into contact with the tip of the button pipe. structure.
