Abstract
A timepiece includes a main plate and gear train bridge with a center wheel and pinion supported therebetween by one or more bearing members integrally formed in the main plate and gear train bridge. A plurality of springs integrally formed in said plate and bridge are used for positioning internal members of the timepiece relative to each other. Additional similar springs are used for fixing the frame structure to the casing of the timepiece. A pressing plate can be connected to the main plate and includes one or more leaf springs for fixing a back cover of the timepiece away from the frame structure. One or more of the plates or bridge can be electrically conductive for delivery of current to an internal member.
Claims9
A timepiece, comprising:
- a timekeeping mechanism including a plurality of internal members for performing functions associated with timekeeping;
- at least two frames positioned in spaced relation, formed of a thin plate material and integrally formed for supporting and positioning at least a portion of a plurality of said internal members, at least one of said frames being formed with a plurality of integral elongated portions deformed out of the plane of the plate in the vicinity of the periphery thereof for providing rigidity to said plate and at least one of the frames including a plate spring formed integrally therein by plastic working for resiliently positioning the height of at least one of the plurality of internal members between said at least two frames by direct pressure exerted by said plate spring on said at least one of said internal members.
