Timepiece
A wristwatch includes a case formed of a glass and a back lid attached to a case body that has an annular receiving portion on an inner peripheral surface thereof. An inner frame is integrated into the case body by engaging an engaging portion of the inner frame with the annular receiving portion from the side of the back lid. A movement is supported inside the inner frame, and a plurality of resilient bodies are attached to the inner frame and project from the outer peripheral surface of the inner frame. The resilient bodies are clamped between the inner peripheral surface of the case body and the outer peripheral surface of the inner frame, and are resiliently deformed so as to match a gap between the inner peripheral surface and the outer peripheral surface.
1. A timepiece comprising:
a case including a body having an annular receiving portion on an inner peripheral surface thereof, a glass attached to the body at one end portion in the thickness direction, and a back lid attached to the body at the other end portion in the thickness direction;
an inner frame which has an engaging portion on an outer peripheral surface thereof and which is integrated in the case by engaging the engaging portion with the receiving portion from the side of the back lid such that a gap is formed between the inner peripheral surface of the body and the outer peripheral surface of the inner frame;
a movement supported inside the inner frame; and
a plurality of resilient bodies attached at a plurality of positions to the inner frame, respectively, and projecting from the outer peripheral surface into the gap, the resilient bodies being clamped in a resiliently deformed state between the inner peripheral surface of the body and the outer peripheral surface of the inner frame.
2. The timepiece according to claim 1 , wherein the inner frame includes a plurality of mounting bores extending in the radial direction thereof, the resilient bodies each include a base inserted into the mounting bore and a head having a diameter larger than the base and the mounting bore and provided integrally at one end of the base, and the resilient bodies are attached to the inner frame with the bases inserted into the mounting bores and the heads projected from the outer peripheral surface.
3. The timepiece according to claim 2 , wherein each of the bases has a cylindrical shape having a hollow portion bottomed by the head, and the hollow portion is opened to the other end of the base.
4. The timepiece according to claim 2 , wherein the heads of the resilient bodies have a semispherical shape.
5. The timepiece according to claim 1 , further comprising resiliently deformable resilient members, separate from and unattached to the resilient bodies, clamped in a resiliently deformed state between the inner frame and the back lid.
6. The timepiece according to claim 5 , wherein the resilient members are each attached by being inserted into a mounting hole provided en in the inner frame.
7. The timepiece according to claim 6 , wherein each mounting hole and the mounting bore have the same diameter, and each resilient body and resilient member have the same configuration.
8. The timepiece according to claim 5 , wherein the resilient members are integrally formed with respective ones of the resilient bodies.
9. The timepiece according to claim 1 , wherein the movement includes a switch, a crown attached to the case and configured to operate the movement, and a push button attached to the case and positioned in the vicinity of the crown and configured to turn the switch ON.
10. The timepiece according to claim 1 , wherein the receiving portion of the body comprises an annular inward projecting portion and the engaging portion of the inner frame comprises an annular outward projecting portion that abuts with an underside of the annular inward projecting portion.
11. The timepiece according to claim 10 , wherein the resilient bodies comprise molded bodies slidably inserted into bores provided in the inner frame, each molded body having a head that projects into the gap and that is clamped in a resiliently deformed state between the inner peripheral surface of the body and the outer peripheral surface of the inner frame.
12. The timepiece according to claim 11 , wherein the heads of the resilient bodies have a semispherical shape.
13. The timepiece according to claim 11 , further comprising resiliently deformable resilient members, separate from and unattached to the resilient bodies, clamped in a resiliently deformed state between the inner frame and the back lid.
14. The timepiece according to claim 11 , wherein the resilient members comprise molded bodies slidably inserted into bores provided in the inner frame.
15. The timepiece according to claim 14 , wherein the resilient bodies and the resilient members have the same configuration.
16. The timepiece according to claim 15 , wherein the resilient bodies and the resilient members have semispherically-shaped heads.
