The assembly according to the invention comprises a hard plastic watch case (2), having on its middle part one or more sealed push buttons (5) made in an inexpensive manner. Each push button (5) comprises a hard plastic stem (10), for example the same material as the case, and an elastomer flexible head (12) which is over moulded onto an external surface (15) of the case. The case and the push buttons may be manufactured by injecting two materials in a single mould. The invention applies to electronic watches and to mechanical watches.

The invention concerns an acoustic alarm safety device comprising a case (2), a vibrating element (20) associated to a membrane (22) so as to make it vibrate, electrical means for providing a control signal to said vibrating element, and means (18) for actuating the electrical means. This device is characterized in that it further comprises a pierced backcover (28) attached to said case (2) and arranged so as to protect it, and so as to allow a vibration of the set of the vibrating element-membrane (20, 22), said backcover being attached to said case in a manually removable manner, and a fitted ring (26) to which is attached said membrane (22), said ring (26) and said membrane (22) being associated to the case in such a way that the set ring-membrane (26, 22) ensures the waterproofness of the case (2).

Electric traction motor vehicle

A vehicle (31) has a composite braking system (electric and mechanical). This composite braking system having asynchronous electric motors (4a to 4d) associated with the wheels (2a to 2d) and a mechanical braking device having a hydraulic circuit (14) and mechanical brakes (18a to 18d). The composite braking system also has an electronic measuring device (36) connected to rotation frequency sensors (34a to 34d) disposed on each of the wheels, this electronic device supplying a reference signal to the control circuit (6) of the asynchronous electric motors which regulate the stator frequency of these motors as a function of the value of the reference signal. The braking system of the invention is anti-locking and very effective in any driving situation.

The wheel drive module comprises a motor (9), a casing (1) partially housing the motor, a wheel support platform (22), a wheel (R) rigidly mounted on the platform, a reduction transmission (31) engaging directly between the motor and the wheel, and a single main transmission shaft (12) bearing the rotor (13) of the motor as well as an input member (35) of the transmission. The casing (1) comprises on the side of the wheel, a fixing shank (18) externally receiving a bearing for said platform (22). The length of the shank is equal to the distance (d) between the input member (35) of the transmission (31) and the free end of the rear part of the platform (22). The reduction transmission (31) is housed in the platform (22). Finally a portion of the main transmission shaft that is torsionally deformable is housed inside the fixing shank.

The vehicle steering control device comprises a steering control member actuatable by the driver and a slaving device comprising two sensors each supplying a detection signal representative, respectively, of the angular position of the vehicle's steerable wheels and of the position of the control member, a motor for pivoting the steerable wheels in response to a control signal, and a slaving circuit producing this control signal in response to the detection signals. The steering control device further comprises a coupling member able to mechanically connect the steering control member to the steerable wheels when the slaving device is not working properly whereby, in such an event, the driver retains control over his vehicle's steering.

This watch case includes a caseband (1) and a fitting frame (2) inserted into said caseband. The frame includes a first seat (14) in which a bezel (4) rests, said bezel compressing the elastic material (15) forming the frame against the caseband, a second seat (16) in which a dial (7) is inserted, a third seat (18) in which a bead (19) provided on the movement rests, and a fourth seat (20) in which a flange (21) exhibited by the back cover (3) is inserted, such flange compressing the material forming the frame against the caseband. The watch case is sealed and lends itself particularly well to assembly on automated machinery.

An object, which is particularly destined for use in horology or jewelry, includes a substrate which constitutes the framework and which is preferably formed from injected cast aluminium. A decorative and protective coating overlays the substrate, such coating consisting of a deposit of a first layer of aluminium in a substantially pure state and a second layer capping the first, said second layer being constituted of aluminium oxide formed from the first layer. The object may be a watch case or a bracelet link.

A case for a wrist watch the caseband (12) of which bears lugs (17) and the back cover (10) of which is provided with a central rib (26) and radial ribs (28a, 28b, 28c). The peripheral end of certain radial ribs (28a, 28c) coincides with the line of extension of each lug (17).

Watchcase and watch provided with such case

The skeleton watch of this invention includes a caseband (1) bearing a frame (6) arranged between an upper crystal and a back cover (26), a leg (8) contiguous to the frame, a motor (10, 11, 12) secured to the frame and including a rotor directly driving a minutes wheel (15) bearing a minutes marker (17). An hours hand (18) is driven by the minutes wheel through motion work including a train of planetary gears (23, 24). Zones (27 to 32) and conductors (33 to 37) are metallized on the internal face of the back cover and are intended respectively to accommodate the electrical and electronic components and establish connections among such components. The arrangement as set forth permits a greatly bared skeleton watch with a minimum of noticeable elements.

The case is essentially made up of a hollow middle cum glass unit (1), consisting of an integral glass pressing, and of a metal back (10) closing off a cavity (5) defined by the inside surface of the hollow unit, the cavity providing a housing for a movement. In the cavity is mounted a metal ring (15) having a centering flange (16) bearing against the middle portion of the unit. In the space between the ring and the middle portion are inserted a deformable rubber gasket (19) and a metal annulus (18) whose radially outer surface is formed with a bevel (18') in the region nearest the gasket. Screws (20) secure the back (10) to the ring (15) and press it against the annulus (18). On being driven home, the screws wedge the bevel (18') between the gasket and the ring thereby to apply a radial force on the gasket . This force presses the gasket against the middle portion of the unit and prevents it from moving out of the cavity.
