Definitions
- the present invention relates to a pendulum for movement timepiece equipped with a device for adjusting its inertia to adjust its oscillation frequency.
- Patent GB-845,773 discloses pendants presenting in their underside adjusting screws whose mass is eccentric with respect to their axis of rotation. If the adjustment of the balance is facilitated by the accessibility of the screws from one of its faces rather than its periphery, the screws overflow from the balancing serge causing turbulence and braking operation of this pendulum. In addition, it is also difficult to ensure desired positioning of the screws in the course of time so that an adjustment of the pendulum is not excluded.
- Document CH-280.067 discloses a pendulum whose serge is provided with recesses opening on its upper face, a pin being driven into the serge in the middle of each recess. Balancing weights are engaged force on these pins and allow according to their angular orientation of modify the inertia of the pendulum.
- the recesses open laterally of the serge and the balancing masses open out of it inducing aerodynamic disturbances disturbing the progress of the balance.
- the machining of the recesses and the driving of the pins in the serge are delicate and expensive operations.
- the object of the present invention is to provide a balance wheel equipped with a precise and continuous adjustment device, easy to realize and adjust causing a minimum of aerodynamic disturbances during the movement oscillating from the pendulum.
- the subject of the present invention is a balance wheel, particularly for watch movement provided with a device for adjusting its inertia to adjust its frequency which tends to achieve the aims stated above and to obviate disadvantages listed above existing devices.
- the pendulum according to the invention is distinguished by the features listed in claim 1.
- the attached drawing illustrates schematically and by way of example a form of the pendulum for a watch movement equipped with a device for adjustment according to the invention.
- Figure 1 is a top plan view of the beam according to the invention.
- Figure 2 is a section along the line A-A of Figure 1.
- FIG. 3 is a partial perspective view on a larger scale of the balance.
- the pendulum for a watch movement in particular provided with a inertia adjustment device for adjusting the oscillation frequency of said balance, comprises an annular serge 1, of circular or cylindrical shape right, connected by radial arms 2 to a hub 3.
- the pendulum has four arms but could have a different number, for example two or six.
- the arms 2 are preferably less thick than the serge 1 as illustrated to the drawing.
- the connection between the arms 2 and the serge 1 is made by curves continuous operation causing the least possible aerodynamic disturbance during oscillations of the pendulum.
- the serge 1 has a circular shape without any protruding part, whether above, below, inside or outside so disturbances due to friction in the air during movements of the pendulum are reduced to the minimum possible.
- the circular serge 1 presents at its intersections with the radial arms 2 a greater width, which allows to practice a circular housing 4 open on one of the faces of the balance, preferably its upper face 5.
- the bottom of this housing 4 is provided with a hole or through passage 6 opening on the other face, the lower face preferably of the serge 1 of the balance.
- This balance still includes adjusting weights 7 with plan views the general shape of a U, inscribed in a circle of a diameter corresponding to the diameter of the housing 4 or slightly higher. So, these Weights 7 can be forced into housing 4 and are completely embedded in these housings, which avoids any friction with the air when pendulum oscillations. During this introduction of the weights 7 in housing, these weights deform elastically and are thus held by friction in their angular position in the housing 4 sub the effect of the inherent elasticity of the weights 7.
- the width of the slot 8 of the weights 7 is smaller than the diameter of the passage 6 so that it is possible using a punch engaged in holes 6 of disengage the weight 7 from its housing 4.
- the balance thus produced has no projection or on its periphery external or internal or on its upper or lower faces, the weights 7 being completely drowned in the dwellings.
- the outer form of the pendulum is simple and continuous, smooth and without asperities and reduces considerably the effects of friction or airflow around the pendulum during his oscillations.
- the adjustment of the daytime running of the watch is done by turning the weights on themselves in their housing 4 in an adjustment range of 360 °, which varies the moment of inertia of the balance. Whatever the adjustment, so the position of the weights 7, the friction of the air caused by pendulum oscillations remains constant and does not influence the walk of it.
- the machining of the balance is simple and only requires holes and millings.
- the adjustment of the position of the weights 7 in the recesses 4 is easy because they are accessible from the upper face of the pendulum and are not in these receptacles only by elastic fixing forces due to the inherent elasticity of these weights 7.
- the described pendulum thus makes it possible to reach the stated goals and to obviate disadvantages of previous achievements, in particular the fact that its superior and inferior as well as its periphery are smooth and free of protrusions and that the adjustment weights are fully embedded in housing provided in the serge.
