Description

[Detailed description of the invention] [Industrial application field] The invention relates to a structure for preventing accidental opening / closing of a front lid of a waterproof watch with a front lid which is used under severe conditions due to high impact such as swimming and sports.

[Outline of the invention]

The present invention is directed to a structure for preventing the lid from being erroneously opened / closed in a waterproof watch with a lid, which locks a groove provided on a button head and a projection provided on the lid, and is mounted on the button. Due to the repulsive force of the coil spring, the amount of engagement between the groove of the button and the protruding portion provided on the outer lid is maintained, and erroneous opening and closing of the outer lid is prevented.

[Conventional technology]

2. Description of the Related Art Conventionally, as shown in FIG. 2, an opening / closing structure of a portable timepiece with a cover has been disclosed by using a repulsive force F of a coil spring b provided on a hinge 11 and pressing the cover 7 in a direction F '. A structure for preventing the erroneous opening and closing of the switch 7 has been known.

[Problems to be solved by the invention]

However, in the conventional opening / closing structure, the lid 7
The force F ′ for holding down is only the repulsive force F of the coil spring 9 and acts only on the predicted external force such as the impact force corresponding to the repulsive force F. When the external force exceeds the repulsive force F of the coil spring 9, the cover 7 The lid 7 is opened without the effect of braking the vehicle.

Further, if the repulsive force F of the coil spring 9 is increased to prevent the lid 7 from opening against external force, the finger cannot be opened and closed.

In view of the above, the present invention has been made to solve the above-mentioned conventional drawbacks and aims to prevent the lid 7 from being erroneously opened and closed regardless of the magnitude of an external force such as an impact applied to the lid 7.

[Means for solving the problem]

In order to solve the above-mentioned problem, the present invention provides a lid cover opening / closing structure to which a high impact force is applied in swimming, sports, etc., in a lid lid button 5 having a groove portion 14 in a button head.
(Hereinafter referred to as a lock button) has a structure in which the button shaft is fixed by a retaining ring 6 of the button from the inside of the body with the waterproof packing 3 and the coil spring 4 interposed therebetween. Groove provided in the head of 5
14 and a protruding portion 13 protruding from the front lid 7 for hanging.
The lock button 5 is pressed by the force when the front lid 7 is closed.
Slides and locks, and the repulsive force of the coil spring 4 mounted in the lock button 5 holds the engagement amount L 'between the protruding portion 13 and the groove 14 to prevent erroneous opening and closing of the lid. did.

[Action]

In the structure for preventing erroneous opening and closing of the front lid configured as described above, the projecting portion 13 provided on the front lid 7 is engaged with the groove 14 provided on the head of the lock button 5 with a hooking amount L '. By doing so, it is possible to eliminate the opening of the front cover 7 and to create a completely locked state.

〔Example〕

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

In FIG. 1, a lock button 5 is slidably assembled via a waterproof packing 3 and a coil spring 4 into a button pipe 2 fixed to one side of a body 1 with a button retaining ring 6 provided at an end. Fixed. The front lid 7 is hinged to a pipe 8 fixed to the other side of the body 1 by a waterproof packing 3 and a transmission pin 10 incorporated via a coil spring 9.
It is supported so as to open and close by an angle of θ with the pin 12 as a fulcrum.

FIG. 4 shows the projection 13 provided on the front cover 7.
But, from the open state of the front cover 7, the groove of the lock button 5 head
FIG. 14 is a view showing an operation when the front cover 7 is hooked, and a force F for closing the front cover 7 is provided by a convex portion provided on the front cover 7 and a groove provided on a collar portion of the head of the lock button 5. The tip of the projecting portion of the lid 7 is engaged and pressed on the slope-shaped portion provided above the 14 to create an effect of pushing the lock button 5 in the W direction by the amount of hook L 'and push the lid 7 in. This creates a locked state.

When the lock is released, by pushing the lock button 5 to the hook amount L 'or more, the hinge 11 is moved by the coil spring 9 via the transmission pin 10 and the hinge
Is opened by being pushed in the direction of rotation about.

In the embodiment as described above, the protrusion 13 provided on the front cover 7 and the groove 14 provided on the head of the lock button 5 are hooked while retaining the hooking amount L 'to swim, Even in a state of receiving a high impact such as sports, the structure of having a locking function can be obtained by eliminating the erroneous opening / closing operation of the lid.

[Effect of the invention]

As described above, the present invention adopts the lock button, which eliminates the erroneous opening and closing of the lid, and allows the lid to open and the cover glass to open even under high shock conditions such as swimming and sports. There is an effect that the case with the lid, which can completely eliminate problems such as breakage and the like and can be used with ease, is easily realized.
