    Abstract: A switch device of the present invention includes a cylindrical member fitted into a through hole of a wristwatch case, an operating member having an operation shaft section to be inserted into the cylindrical member and an operation head section, and a lock member fixed inside the operation head section. The cylindrical member includes engaging projections, and the lock member includes resilient support sections which have a space with respect to the inner circumferential surface of the operation head section and are resiliently deformed in a radial direction, and lock sections with which the engaging projections are resiliently engaged. Accordingly, when the operating member is pushed inward and rotated, the engaging projections resiliently deform the resilient support sections and are engaged with the lock sections. Also, only by the operating member being rotated against the regulating force of the lock section, the lock sections are disengaged from the engaging projections.

    Abstract: A switch device of the present invention includes a cylindrical member attached to a through hole of a wristwatch case, an operation member having an operation shaft section inserted into the cylindrical member and an operation head section provided at the outer end of the operation member, a cushioning member attached to the operation head section of the operation member to cover the operation head section, and an exterior member fixed to the operation head section to cover the cushioning member and from which a plurality of portions of the cushioning member project outwardly. Therefore, when the exterior member receives an external impact, the impact can be mitigated by the cushioning member projecting outwardly from the exterior member. As a result, the operation member and the cylindrical member can be prevented from being damaged by the external impact, whereby the impact resistance can be increased.

  • Patent number: 6527436
    Abstract: A watch has a switch mechanism 10 supported by a base 11 and a lid 13 that houses a generally conventional electric watch arrangement (not shown). The mechanism includes a semi-circular disc shaped finger tip engagable pusher 16 that can be rotated in either direction from a mean position, and also pushed radially inwards. Such movement of the pusher 16 produces radial movements of biassed plungers 23, 26 and 30 that are urged through respective apertures 24, 27 and 31 in a wall 12 of the base 11. As a result respective electrical circuits of the watch arrangement are closed to change watch functions. The mechanism 10 serves the same purpose as push buttons conventionally used in the prior art but is much easier for the user, especially if the watch is being worn on a wrist when watch functions need to be changed.

    Abstract: A control device with a snap function includes a support (10), a push-button (12) mounted so as to move in translation along an axis on the support, and a spring element (14) which is not secured to the support or to the push-button. The spring element (14) is formed of an elongated sheet made of resilient material, inserted between the push-button (12) and the support (10), and includes a pair of support zones (36) located at its ends and at least a median support zone arranged in its central portion. These support zones cooperate respectively with the head (28) of the push-button and with a raised surface (24c) of the support. In the rest position, the sheet has a bent or V-shaped cross section, which can deform to create a snap action during the travel of the push-button which tends to bend the spring element longitudinally. Such a device can be applied to control a mechanical or electrical function of a watch or another apparatus of small size.

  • Patent number: 6422740
    Abstract: The present invention concerns a wristwatch type of watch. More specifically, the watch comprises a display (11), an electronic circuit (12) controlling the display, a time set stem (13), and at least two electrical contact elements (14, 14″). The time set stem (13) can be placed in different axial positions and the stem comprises a crown (16) accessible from outside the watch and a helicoidal zone (19) which may have three helicoidal elements (20, 20′, 20″). When the time set stem is placed in a position such that the contact elements (14, 14″) are facing the helicoidal zone (19), rotating the time set stem causes an electrical connection on the electronic circuit (12) to alternately open and close. This generates at least two electrical impulse signals which are transmitted to the electronic control circuit. These signals are used to regulate different watch functions, such as time correction or controlling the time belt or the date.

  • Patent number: 4509867
    Abstract: An electronic timepiece movement includes a control stem slidably guided in a radial passage of a base plate. Pulling on this control stem brings a return spring acting on the stem into contact with a stud which is carried by the substrate of an electronic circuit module of the movement. This connects a conductive lead to ground, which controls an operation function of the timepiece. The pull-out control stem and associated return spring can be replaced by a push-in member and by a return coil spring located in said passage. The stud is then positioned in a hole of the substrate of the electronic circuit, which hole is situated opposite to the longitudinal axis of the passage. Pressure exerted on this push-in member places a portion thereof into electrical contact with the stud and this connects the lead to ground, as before. Thus, the movement can according to choice be completed for operation either by a push-in control movement or by a pull-out control stem movement.

  • Patent number: 4264969
    Abstract: In order to simplify the production of electronic watches, there is provided a family of standardized movements whose members can be housed within a variety of watch cases of different size and shape. All movements in the family are identical but for their mounting plates which differ in size, and in some instances also in shape, to render the movements receivable in differently-configured cases. The standardized movements in the family include batteries of different size which take advantage of the space made available by the plates of different size to afford optimum battery life.
