The connecting portion of the lid through which the pin penetrates is provided with a protrusion protruding outward. And
When the lid is rotated, the protrusion slides on the case, and the lid is displaced away from the case. Then, the pin and the elastic body are pressed against each other, and the elastic body is compressed and deformed. Therefore, a predetermined torque is applied to the rotation of the lid. In addition, the lid can be stopped at an appropriate position in the rotation range of the lid.

I got on. Further, when the pin is bent or broken due to the compressive deformation force of the elastic body, the lid sometimes comes off the case.

があった。[0007] In the mounting structure of Japanese Utility Model Laid-Open No. 5-87593, the pin is fixed to the case in a non-rotatable manner. For this reason, since the screw portion formed on the pin and the screw portion formed on the case must be screwed, the processing load is large. In addition, when the pin rotates together with the rotation of the lid and the screwing of the pin and the case is loosened, the lid sometimes comes off the case.

緩んでしまったり、係合できなくなったりした。Further, in the engagement structure of Japanese Utility Model Laid-Open No. 55-30886, when the lid is made of a material having no wear resistance, such as titanium, brass, or aluminum, the engagement with the protruding pin causes the recess of the lid to be closed. The edges were easily worn. Therefore, when used for a long period of time, the engagement between the lid and the pin is loosened or cannot be achieved.

性体を圧縮し、回転支軸の外周と蓋の孔との間に第２の
弾性体を圧縮したことを特徴とする。In order to achieve the above-mentioned object, according to the present invention, there is provided an open / close structure for a watch case with a cover, comprising: a cover rotatably attached to the watch case by a rotation support shaft. An opening and closing structure for a cover of a watch case, wherein a rotation support shaft is loosely inserted into a hole of the watch case and a hole of the cover, and a first elastic body is provided between an outer periphery of the rotation support shaft and a hole of the watch case. , And the second elastic body is compressed between the outer periphery of the rotation support shaft and the hole of the lid.

り使用しても蓋がケースから外れない。With this configuration, when the lid is rotated, at least one of the compressed first and second elastic bodies is brought into friction with at least one of the rotation support shaft or the hole of the watch case or the lid. Slide on. This allows
When the lid is rotated with respect to the watch case, a predetermined torque is applied to the rotation of the lid. In addition, the lid can be stopped at an appropriate position in the rotation range of the lid using the torque. In addition, the rotation support shaft is held through the compressed elastic body so as not to fall out of the hole of the watch case or the hole of the lid. Thus, with a simple structure, torque can be applied to the rotation of the lid without damaging the lid or the case. In addition, the lid does not come off the case even after long-term use.

回転できる。Further, the watch case is provided with a connecting foot for connecting the band, and one end of the rotating support shaft is inserted into a hole of the connecting foot. With this configuration, one end of the rotating spindle is not visually recognized from the outside, so that the appearance is not spoiled. In addition, since the backlash of the rotation support shaft is suppressed, the lid can rotate smoothly.
【００１３】また、第２の弾性体が時計ケースの孔と連

しないので、蓋がケースから外れる危険を排除できる。[0013] The second elastic body has a size that cannot pass through the hole of the watch case and the hole of the connecting foot. With this configuration, the second elastic body does not come out of the hole of the lid, so that the risk that the lid comes off the case can be eliminated.

ことで維持される。A plurality of first elastic bodies are arranged in a hole of the watch case. With such a configuration,
Since the length of each of the first elastic members along the axial direction of the rotation support shaft can be reduced, the first elastic members are less likely to climb due to the rotation of the lid. This ensures smooth lid rotation. In addition, the risk of the elastic body being broken is eliminated, and the elastic body can be used for a long time. Further, the magnitude of the torque applied to the rotation of the lid and the magnitude of the fixing force for preventing the connection support shaft from coming off are maintained by increasing the number of the first elastic bodies.

り使用できる。Further, an intervening member is arranged between the first elastic members. With this configuration, the movement of the first elastic body along the axial direction of the rotation support shaft is suppressed by contact with the intervening member. This eliminates wear and torsion caused by the movement of the first elastic body, so that smooth rotation of the lid is ensured and the elastic body can be used for a long time.

排除される。Further, the present invention is characterized in that the intervening member is a pipe into which the rotating shaft is inserted. With such a configuration, it is inexpensive and easy to assemble. In addition, since the pipe is supported on the rotating shaft, the risk of bending or breaking the pipe is eliminated.

る。Further, there is provided an opening / closing structure for a watch case with a cover having a cover rotatably attached to the watch case by means of a rotating support shaft, wherein the cover is engaged with the case at a position where the cover is closed with respect to the case. A separate pipe having locking means, the locking means including an engagement projection provided on one of the lid and the case, and a recess provided on the other of the lid and the case, wherein the engagement projection is inserted into the recess. Is fixed.

Since the end of the rotating shaft 10 is not visible from the outside, the aesthetic appearance of the watch case 2 is not spoiled. Further, the contact with the hole 21a suppresses the rattling of the rotation support shaft 10. Further, since the second elastic body 14 cannot pass through the connecting hole 22 a of the watch case 2 and the connecting hole 21 a of the connecting foot 21, the second elastic body 14 does not come off from the hole of the lid 3. Therefore, the risk that the lid 3 comes off the case 2 is eliminated. This is 2
Since the individual elastic members 14 do not fall out of the lid 3, the elastic members 13 located between the elastic members 14 do not fall out of the case 2. Thus, the hinge part 4 is configured.

方に慴接指せても良い。The rotational torque applied to the lid 3 by the hinge 4 is determined by the amount of compression of the first elastic body 13 and the second elastic body 14. That is, the amount of compression of the second elastic body 14 may be increased, and the second elastic body 14 and the rotating shaft 10 may be rotated together with the lid 3. Then, at least one of the friction between the compressed first elastic body 13 and the rotating shaft 10 or the friction between the first elastic body 13 and the connection hole 22a of the watch case 2 causes. , Lid 3
A predetermined torque is applied to the rotation of. Conversely, the amount of compression of the first elastic body 13 may be increased to hold the first elastic body 13 and the rotation support shaft 10 so that they cannot rotate with respect to the watch case 2. Then, at least one of the friction between the compressed second elastic body 14 and the rotating shaft 10 or the friction between the second elastic body 14 and the connection hole 33a of the lid 3 causes A predetermined torque is applied to the rotation of the lid 3. Alternatively, by adjusting the compression amount, the first elastic body 13
Alternatively, both the second elastic body 14 and the rotating shaft or the connecting hole 33a of the watch case 2 or the cover 3 may be slidably contacted with the rotating shaft.

As shown in FIG. 6, the locking means 5 is formed by press-fitting an engagement protrusion 28 into a connection hole 24 a of a connection foot 24 of the watch case 2. The engaging projection 28 accommodates a spring 28B in a cylindrical case 28A, and further accommodates a ball 28C against the urging force of the spring 28B to slightly caulk the opening to seal the ball 28C. Mechanism. On the other hand, a pipe 29 made of a material having excellent wear resistance, such as a separate stainless steel, which is a concave portion into which the ball 28C of the engagement protrusion 28 is inserted, is fixed to the connection hole 33a of the lid 3. The pipe 29 has a substantially cylindrical shape, and has an opening 29A for locking the ball 28C and a pool groove 29B formed on the outer periphery. An adhesive is applied to the pool groove 29B, and the pipe 29 is pressed into the connection hole 33a and fixed.
