摘要:
A mechanical timepiece movement in the form of a modular unit. The movement includes at least one modular unit for performing a particular timepiece function, which is irremovably pre-adjusted by irremovably securing adjustment and/or assembling components included in the functional module after the particular horological function has been adjusted and function checked on the test bench. The pre-adjusted functional module is irremovably secured to a plate included in the movement or included in another pre-adjusted functional module of the movement, or irremovably secured to another pre-adjusted functional module included in the movement.

An intermittent blocking mechanism for at least one escape wheel, that intermittent blocking mechanism cooperating with at least one regulating member or a balance which is actuated with an alternate motion under action of an elastic return mechanism, the intermittent blocking mechanism being pivoted in at least one bottom plate, and forming an inseparable single-piece component with the bottom plate. The intermittent blocking mechanism includes at least one pallet lever in a single-piece with the plate to which it is connected by the elastic return mechanism.

A timepiece mechanism structure for receiving and guiding at least one pivoting wheel set is provided. The structure includes at least one inseparable single-piece structure, including one inseparable single-piece frame which includes pivot housings aligned in pairs in a direction of alignment for receiving the pivots of an arbour of this pivoting wheel set, and each pivot housing is an open housing formed by a half bearing or by a dihedral, and includes at one end a stop bearing surface in this direction of alignment.

A structure includes a wristwatch case; an inner frame arranged inside the wristwatch case and having an upper surface provided with a positioning fitting recess; a timepiece module arranged as being positioned inside the inner frame; and a parting plate which is provided with a positioning pin that is provided on a lower surface of the parting plate facing the upper surface of the inner frame, and that is fitted into the positioning fitting recess of the inner frame, thereby positioning the parting plate with respect to respect to the inner frame. As a result, in a state where the timepiece module is arranged and positioned inside the inner frame arranged in the wristwatch case, the positioning pin of the parting plate can be fitted into the positioning fitting recess of the inner frame. Accordingly, the parting plate can be accurately positioned with respect to the inner frame.

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.

An inner frame includes a side wall being set its outer diameter to be smaller than a diameter of an inner periphery of a case and arranged along an inner peripheral surface of the case when the frame is housed within the case. The wall is divided into spread portions by cut outs, each cut out in a thickness direction of the case, and the spread portions are spread to make an outside surface thereof fit on the inner peripheral surface of the case when the module is press-fitted from an opening of the case. An inside surface of each spread portion is provided with a projection to be brought into contact with an outside surface of the module and to push and spread outward the spread portion when the module is press-fitted into the frame. A case unit includes the module, the case, and the frame.

The invention relates to a mechanism for the positioning of wristwatch control elements, whereas such control element may be implemented as a crown intended for the adjustment of the watch—as well as winding up the energy storage spring, for mechanical watches—or a pushbutton, and it is embedded in a hole in the watch case in an axially movable manner. The position mechanism contains a seat for the control element, as well as an actuating element linked to the control element from the side through at least one drive element designed to move the control element in its normal position countersunk in the seat, or one or more elevated operating positions.

The push-button control device for a watch includes a push-button stem (28) inserted via a bottom end into an orifice (22, 23) of a watchcase and a button (29) mounted on a top part (28a) of the stem (28) outside the watchcase. The stem can slide axially between a rest position and an active position against a return member (35) to control at least one function of the watch. The control device is characterized in that the top part (28a) of the stem includes an annular groove delimited by two parallel shoulders (44, 46) perpendicular to the axis of the stem, and in that the button (29) includes an annular base (27) that is engaged in the groove so as to be held between the two shoulders (44, 46) in the axial direction and centred with some play by the bottom of the groove such that the button (29) is free to move off-centre relative to the axis of the stem (28) while remaining secured thereto.
