专利汇可以提供Timepiece sealed with heat shrinkable resin专利检索,专利查询,专利分析的服务。并且PURPOSE: To obtain a timepiece structure for dust-, sweat- or waterproofing which has sureness and permits reduction in cost by coating the timepiece with a heat shrinkable resin and using a smaller number of parts and simple techniques.
CONSTITUTION: A module 1 is sandwiched by two sheets of film-shaped heat shrinkable materials 2 consisting of the transparent heat shrinkable resin such as PVC or olefin and the materials 2 are heated and shrunk by hot wind, etc., to bring the same into tight contact with approximately the entire surface of the module 1. The material 2 on the front face of the timepiece assures a space 11 for the hands by the presence of a dike 12. A switch button 3 is pushed from beyond the film of the material 2 to apply and external operation input to the timepiece function, etc. An oscillation diaphragm 6 which is adhered with a piezo-electric element 7 and generates acoustic signals such as alarm sounds is held in tight adhesion under the high pressure uniformly over the entire surface by the material 2 and the shrinkage force thereof, by which the clattering of sounds, etc., are prevented. Since the sealed module 1 has no problems any longer in waterproofness, the module can be put into a case 4 integrated with, for example, a band having many spacings.
