摘要:
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 precision, reliable, analog timepiece uses plastic frame elements reinforced with metal, and plastic wheel and pinions pivoting in holes formed in the plastic of the frame elements. The plastic frame elements are separated into portions corresponding to the functional timepiece portions. Exposed areas of the reinforcing metal provide reference locations in molding the frame elements and for component mounting. The entire timepiece is assembled from one side of a base frame element.

The back cover (51) of the watch case carries a middle-bezel and forms a plate. At its center there are superimposed and concentrically pivoted, respectively, a ratchet crown-wheel (1.6) inside which a mainspring is housed, driving a core (1.3) fast with an hour-disc (1.1) comprising a toothing on its periphery, and a transparent minute-disc (1.2) comprising also a toothing on its periphery. These discs mesh on the one hand with a drive train (2, 3, 4) by which the minute-disc is driven by the hour-disc and, on the other hand with a winding and time-setting mechanism both located outside of the discs and at least partially at the same height as these discs.

The reduction gear of an electronic wristwatch comprises three concentric output shafts adapted to be rotated at different speeds and operatively connected with each other and with the shaft of a stepping motor through gear wheels. A shaft making one revolution per hour has mounted thereon a friction wheel and a bearing means made in the form of a supporting bush press fitted in a bore of the plate of the wristwatch. The bush is mounted so that a portion thereof projects from the plate toward the bridge of the wristwatch, coordinated with respect to the plate and attached thereto by threaded means. The shaft passes freely through a bore in the supporting bush and is restricted from an unlimited axial displacement in one direction by an end face of the supporting bush, and in the other direction by the end face of that pinion which is mounted on the shaft with interference fit. The reduction gear of an electronic wristwatch can be used by the watch-making industry in the production of quartz wristwatches having a stepping motor, and of like timepieces.

Two bridges of thin sheet material are spaced apart by means of pillars having a plurality of shoulders. A third sheet member is held intermediate the two sheet members by means of shoulders on the pillars. A portion of the intermediate sheet member is turned at right angles to the remainder of the sheet and is apertured for reception of the stem. The intermediate sheet member also serves to hold in place gears between the third sheet member and one of the two bridge members during emplacement of the other bridge sheet member on the pillars.
