Title:
STRUCTURE OF WATCH
Document Type and Number:
Japanese Patent JPS60165575
Kind Code:
A
Abstract:

PURPOSE: To obtain a watch structure having excellent wearing performance by coupling a rigid body part which protects a watch module and a deformable part consisting of a freely deformable material by means of a spring part.

CONSTITUTION: An upper leaf spring 5 is welded to a spring holding part 3b and a lower leaf spring 6 is welded to the surface of a rear cap 4. An element block 2 is housed in an insulation-coated module part 3a of a base body 3 and the back 4 is screwed thereto. A deformable body 7 is inserted between the springs 5 and 6 and the top end 7a is engaged with the lower part of the spring part 3c of the body 3. A resin tube 8 is put on the base body in such a way that the transparent window 8a is positioned on a time display surface 2a. The central part of the body 3 acts as a rigid structure to protect the block 2 but the spring part 3c is tapered toward the outside and has therefore the gradually increasing elasticity. The deformable part consisting of the body 7 composed of a freely deformable material such as lead or the like and the springs 5, 6 starts from the part where the spring part 3c ends. Thus even if the watch 1 is curved, the display part 2a does not deform the shape thereof but the spring part 3c curves gradually and the deformation thereof is transmitted to the deformable part, by which wearing to the wrist, etc. is made possible.
