摘要:
The invention concerns a push button device for a timepiece, in particular a chronograph, including a pusher head (2) associated with a pusher stem (4) arranged so as to slide in a recess (6) inside which it moves axially from a rest position against the resilient return force of a spring (12) when the pusher head (2) is pushed in, characterised in that the pusher stem (4) is also able to move axially from its rest position to a pulled out position when the pusher head (2) is pulled out.

The present invention concerns a device for mounting a source of electric energy (100), preferably a button-type battery, for a portable electronic apparatus including a housing (3, 44), closed by a cover (14, 49), for said energy source. The housing includes, in proximity to its periphery, tongues (5, 32) that can be deformed for holding the energy source axially in the housing. Further, the cover includes a wall (15, 50) projecting into the housing and arranged between the periphery of the housing and the tongues retaining the energy source. The wall of the cover thus ensures that the tongues are held properly against the energy source when the latter is arranged in the housing, in particular in the event of a violent shock.

The invention proposes an arrangement for the mechanical interfacing of a micromotor of the MEMS type with a toothed wheel in which the micromotor is produced in the upper layer of a plate made of crystalline or amorphous material and comprises at least one actuator which drives a rotor in rotation, characterised in that a pinion, coaxial with the rotor and arranged above the rotor, is connected in rotation to the rotor by means of at least one pin which is received in an associated housing and in that the pinion meshes with the toothed wheel.

There is disclosed a portable electronic instrument, such as a wristwatch (1), including a case (2) enclosing an electronic module (6) and a display device (5), a crystal (3) fitted onto the case (2), an electric power supply source (4) housed in the case (2) and powering the electronic module (6) and the display device (5), and an antenna (20) for receiving and/or transmitting radio-frequency signals electrically connected to the electronic module (6). The case (2) includes an exterior body (4) including a bottom (4a) and lateral walls (4b) and a bezel element (7) fitted onto the exterior body (4) and supporting the crystal (3). The antenna (20) rests on an outer face (7a) of the bezel element (7).

The transmission device disclosed is inserted between a rotating oscillating weight and an electric micro-generator in order to drive the generator rotor from the oscillating weight by multiplying the rotational speed. Its intermediate wheel and pinion includes a barrel (27) whose central shaft (24) is coupled to the drum (41) of the barrel by a spiral spring (30). The inner end of the spring has a bent portion (34) which engages via resilience in any one of a number of hollows (51) in the shaft and can be released by sliding over a slanting side (52) when the shaft exerts too great a torque in the given rotational direction. This arrangement prevents damage resulting from shocks, in particular in the case of a watch, without using a friction system.

An electric switch device (14) co-operating with a printed circuit (13) and closing perpendicular to such circuit when it is actuated by a pressure in a direction (A) parallel to the plane (16) of the circuit. The switch comprises an elastic contact element (22) having a prominent portion (25) which receives the pressure from a push-button (4) in a direction (A) parallel to the printed circuit. At least one flexible leg (28) of the contact element is fixed to the printed circuit or close to the latter. Another leg (26) of this contact element carries at its end a contact portion (27) which is lowered onto a pad of the circuit when the contact element bends under the effect of the control pressure.

The device includes a barrel (2) inserted in the kinematic chain between the rotor (11) of the generator (1) and the oscillating weight (3). The barrel includes a spiral coiled spring (4) and a sliding strip (6), wound in the same direction as the spiral coiled spring over the length of a turn, without any mechanical connection with the spring, but forming a protective envelope in the open position in case of shock. The shockproof device can be applied to the generator of a wristwatch.
摘要:
The invention relates to a watch comprising a device for indicating the temperature (16) of the environment in which the watch is situated comprising a first series of thermochromic liquid crystal temperature sensors (18) facing a first temperature scale (20) arranged in such a way that the reading given by the sensors (18) of the first series, in combination with said scale, is directly representative of the temperature of the environment in contact with the sensors, and wherein the device differentiates the temperature indicated by the sensors according to whether the watch is worn or not worn.
摘要:
The connection arrangement of this invention includes one or several sets of electrical contacts, respectively within the case of an electronic appliance and the bracelet thereof. These contacts are separable by virtue of being associated with elastic latching means. Moreover they are surrounded by a complementary abutment surfaces which protect them from all damaging influence coming from the exterior (in particular that resulting from corrosive substances which may be exuded by the wrist). These surfaces are firmly applied to one another by the latching force of the contacts.The invention may be applied in particular to any timepiece having a bracelet.
