Abstract

A timepiece includes a movement contained in a timepiece exterior assembly. A panel is fixed onto the movement. Upward engagement convex portions having pressing portions in upper portions thereof are formed in a plurality of locations of the ring member, and a ring member is fixed to the peripheral portion of the movement. A display plate has a plurality of reception portions in a peripheral portion thereof with which the pressing portion comes into contact from above. The reception portions are vertically interposed by an upper surface of the ring member and the pressing portions, the display plate is attached to the ring member, and the panel is covered with the display plate.

Claims (14)

1. A timepiece comprising:

a timepiece exterior assembly;

a module disposed in the timepiece exterior assembly;

a panel fixed to the module;

a ring member fixed to a peripheral portion of the module and having upward engagement convex portions provided thereon at a plurality of locations, the engagement convex portions having pressing portions; and

a display plate disposed to cover the panel and having a plurality of reception portions in a peripheral portion thereof with which the pressing portions come in contact from above, the reception portions being vertically interposed by an upper surface of the ring member and the pressing portions and being attached to the ring member.

2. The timepiece according to claim 1 , wherein pressing portion accommodation grooves opened to the peripheral surface of the display plate are formed in a plurality of locations of the peripheral portion of the display plate, the reception portions are provided so as to partition a part of the pressing portion accommodation grooves, and the pressing portions are housed in the pressing portion accommodation grooves.

3. The timepiece according to claim 2 , wherein the reception portions have reception slope surfaces that partition a part of the pressing portion accommodation grooves, the reception slope surfaces face a width direction of the pressing portion accommodation grooves and are widely formed as the pressing portion accommodation grooves face upward, and the pressing portions have pressing slope surfaces coming into contact with the reception slope surfaces from above, respectively, and are widely formed as the pressing portions face upward.

4. The timepiece according to claim 2 , further comprising mutually opposite groove side surfaces of the pressing portion accommodation grooves, wherein the reception portions have reception slope surfaces that partition a part of the pressing portion accommodation grooves, the reception slope surfaces are formed on bottom surfaces of the pressing portion accommodation grooves sloped down as the reception slope surfaces face open ends of the pressing portion accommodation grooves, the pressing portions have slope side surfaces sloped so as to approach each other as going to tip sides thereof and are formed in a tapered shape, the tip portions of the pressing portions come into contact with the reception slope surfaces from above, and the slope side surfaces come into contact with corners formed by the groove side surfaces and the peripheral surface of the display plate, respectively.

5. The timepiece according to claim 1 , wherein each engagement convex portion is able to be elastically deformed in a radial direction of the ring member and the display plate based on a root thereof.

6. The timepiece according to claim 5 , wherein a contact projection coming into contact with an inner peripheral surface of a body included in the timepiece exterior assembly is integrally provided in an upper portion of each engagement convex portion.

7. The timepiece according to claim 2 , further comprising an annular clearance which comes into contact with an upper surface of the peripheral portion of the display plate and covers the peripheral portion, and a wherein height of the upper end of the pressing portion is equal to or less than the upper surface of the display plate.

8. The timepiece according to claim 1 , wherein the panel is a solar battery panel that generates electricity by a photoelectric conversion.

9. The timepiece according to claim 1 , wherein the panel is a light emitting panel that emits light in an electrically conducted state.
