Definitions
- the invention relates to a spring for a watch mechanism or a clock mechanism spring.
- the invention also relates to a clock mechanism, in particular a correction mechanism or a calendar mechanism, comprising such a spring.
- the invention also relates to a watch movement comprising such a spring or such a mechanism.
- the watch mechanisms are generally provided with springs, levers and cams which are provided to cooperate to perform various functions of a watch movement. Energy, taken from the motor or provided by the wearer of the wristwatch, is thus accumulated and returned by the springs so as to guarantee the functions, all in a limited volume.
- the volume available does not make it possible to implement a leaf spring, possibly integral with a lever, whose elongated geometry is shaped so as to minimize the mechanical stresses within it, which leads to spring geometries in which the mechanical stresses are very important compared to the forces to be provided.
- it is not easy to adjust such a spring with regard to the different forces that it is likely to provide and the various functions that it is likely to fulfill.
- Patent Application FR204371 1 discloses a "V" shaped spring lever which is manufactured in one piece. This one is dedicated to an update mechanism. Its spring portion is perfectly blocked by two stops so that it arches when moving its lever part so as to cause a restoring force. This configuration of the lever-spring is not optimal compared to the angular rigidity that may require such a component to optimize the forces at the stem and thus maximize the comfort of the wearer of the watch.
- the attachment points of the spring affect the pivoting of the zipper and the positioning of the sliding pinion.
- the patent application EP2015146A1 relates to an instantaneous jump date device.
- a conventional energy accumulator which is consisting of a spring, a rocker and a cam integral with a calendar finger date.
- the spring through the rocker which is pressed against the cam, accumulates the energy required to allow an instant jump of the date.
- the spring is shaped to produce forces adapted to allow this jump. More particularly, it has an elongated blade shape particularly bulky which aims to reduce the mechanical stresses within it with respect to the forces it must provide.
- This spring is pivoted at a single pivot point which is substantially in the center of the blade.
- a first end of the spring is in abutment against the frame of the watch and a second end plate the rocker, so that the spring arches when moving the cam so as to cause a restoring force. It appears that with such a configuration of the spring, the energy that can be accumulated in the spring is low at given internal maximum stress.
- the object of the invention is to provide a clock mechanism spring to overcome the disadvantages mentioned above.
- the invention proposes a spring that makes it possible to minimize the mechanical stresses it undergoes when it is stressed within a given space and also makes it possible to easily adjust the forces that it produces.
- the invention also proposes a spring whose geometry is particularly suitable for industrial production.
- the watch mechanism spring comprises a body extending between a first end of the spring and a second end of the spring.
- the spring comprises, between the first and the second end, at least one member intended to act by contact on an element of the watch mechanism.
- the body comprises a deformable zone extending along a curve.
- the curve includes a first concave portion viewed from the first end.
- the spring is intended to be mechanically linked to a frame at each of the first and second ends.
- a watch mechanism is defined by claim 21.
- a timepiece is defined by claim 22.
- Figure 1 is a schematic view of a timepiece having a first embodiment of a watch spring according to the invention.
- Figure 2 is a view of a watch spring according to the prior art.
- FIG. 3 is a view of a graph showing the evolution of the force provided by a spring as a function of its deformation in the cases of the spring of FIG. 1 and the spring of FIG. 2 known from the prior art.
- Figure 4 is a view of a second watch spring variant according to the invention.
- a timepiece 300 according to the invention is described below with reference to FIG.

- the timepiece comprises a watch movement 200, in particular a watch movement of the mechanical type.
- the watch movement includes a mechanism 100, in particular a mechanism including an element 42 and a spring 10.
- the invention is illustrated by two specific applications.
- the first concerns a lever-spring correction clock mechanism
- the second application relates to a spring lever mechanism calendar.
- the lever-spring or spring is intended to accumulate a mechanical energy and then return it to the element - cam or pinion or wheel - of the clock mechanism with which it cooperates. This energy is restored at least partly and almost entirely in the form of mechanical work.
- the spring is linked to a frame which is integral with the timepiece.
- the clock mechanism 100 is a correction mechanism that makes it possible, for example, to correct the indication of the time, the date indication correction or the correction of any other indication.
- the mechanism comprises a spring 10.
- the mechanism also comprises a frame and a movable member 42 relative to the frame. A surface of the spring acts by contact on the movable element.
- the spring and the element are arranged so that the member restores energy, particularly in the form of mechanical work, to the element.
- the element comprises a cam and / or a pinion and / or a wheel. In the example of Figure 1, the element is a sliding pinion.
- a first variant of the spring is for example designed to cooperate by contact action on the sliding pinion of a mechanism for correcting and / or setting the time of the timepiece. It is movable axially between a meshing position with a correction return 43 and a non-meshing position of the pinion and the return.
- the spring makes it possible to return the sliding pinion to the non-meshing position (represented in FIG. 1).
- This spring 10 comprises a body January 1 extending between a first end 12 of the spring and a second end 13 of the spring.
- the spring is intended to be mechanically linked to a frame at each of the first and second ends.
- the spring comprises, between the first and the second end, at least one member 17, in particular a lever, intended to act by contact on the element 42 of the watch mechanism.
- the body comprises at least one deformable zone 14 extending along a curve 18.
- the curve comprises a first concave portion 18a seen from the first end.
- the zone 14 has a substantially rectangular section that is highly deformable under an action of a given intensity. This zone is located between the points 12a and 13a of the respective ends 12 and 13 beyond which the section of the body 1 1 of the spring 10 varies substantially.
- the spring 10, in particular the lever 17, comprises a first connecting element 15 pivoting to the frame at the first end 12.
- the second end 13 of the spring 10, which is in particular in the continuity of the deformable zone 14 of the spring 10 or adjacent to the deformable zone 14, comprises a second element 16 connecting pivot to the frame.

- the second connecting member preferably comprises a bore or a bore portion 16 for receiving an axis mounted on the frame.
- a connecting element comprises a bore portion
- the spring can be engaged on an axis fixed to the frame.
- the lever 17 is pivoted about a pivot axis 19 located at the first end, in particular around the axis of the mechanical connection connecting the spring to the frame.
- the curve 18 along which extends the zone 14 of the body 1 1 of the spring 10 between the points 12a and 13a has a generally concave portion 18a and a rectilinear or substantially rectilinear portion 18b.
- This curve 18 is generally concave seen from the first end 12, in particular from the axis 19 of the first connection means 15.
- the lever 17 is connected to the deformable zone 14 away from the pivot axis 19, in particular more than a third of the length L of the lever, or more than half the length L of the lever, or at the end or substantially at the end of the lever. It is considered that the zone of contact of the lever to the element 42 constitutes the end of the lever, even if the lever physically extends beyond.
- the length L is measured between the pivot axis 19 and the contact zone.
- the distance D between the first and second ends, in particular between the axis of the first connecting means and the axis of the second connecting means is less than 5 mm, or even less at 2 mm, or even less than 1 mm, and / or less than 8 times the thickness E of the ends 12 and 13 of the spring, preferably less than 6 times the thickness E of the ends 12 and 13 of the spring.
- the thickness E of the spring is measured perpendicular to the plane of FIG.
- the distance D is of the order of 2 mm and the thickness E measured at the ends 12 and 13 is of the order of 0.3 mm within the spring 10 which is illustrated in FIG.
- the element 42 moves by at least 0.3 mm, or even at least 0.5 mm, or even at least 0.7 mm relatively to the frame, during a transition from a configuration of maximum stress in the spring to a configuration of minimum stress in the spring.
- This displacement takes place under the effect of the return of the mechanical energy stored in the spring, especially in the form of mechanical work.
- the lever 17 can move by at least 5 °, or even at least 10 °, about the axis of a connecting element 15.
- the angle ⁇ formed by the two half-lines originating at the end 12, in particular the axis of the first connecting means 15, and passing respectively through the end 13, in particular through the axis of the second connecting means 16 and the center of gravity 1 1 g of the body 1 1 of the spring is preferably less than 120 °, or even less than 90 °.
- the angle ⁇ is of the order of 60 ° within the spring 10 which is illustrated in FIG.
- the line D1 passing through the axes of the mechanical links linking the spring frame allows to define a first and a second half-planes located on either side of this line.
- the lever 17 extends along a half-line 191 included in the first complementary half-plane of the second half-plane in which extends a portion of the deformable zone from the second end, that is to say where extends a portion of the deformable zone from the second end or directly in contact with the second end.
- the deformable portion in the second half-plane is preferably concave.
- the deformable portion in the second half-plane may comprise or be all or part of the concave portion 18a of the curve 18.
- Figure 2 illustrates a spring known from the prior art.
- This spring 1 10 is pivoted about an axis 1 13 and is provided to maintain in position, with a finger 1 18, the pinion 42 remote from a correction ring 43 when a rod is disposed in a first position.
- the section of the flexible portion 1 14 of the spring is then defined to ensure the good holding force.
- the passage from a non-correction position to a correction position causes the wearer of the watch to pull the rod and thus to overcome the force produced by this spring. For some axial displacement of the rod, this force may be too large and may degrade the sensations during handling of the rod.
- a particularly advantageous solution therefore consists in implementing a spring such as represented in FIG. 1 within a clock mechanism because this latter, by virtue of its low angular rigidity, can be adapted in order to minimize the forces involved within of the mechanism while guaranteeing the minimum forces required for the proper functioning of the device.
- the spring can thus be prestressed optimally.
- the distance between the two connecting axes of the spring could also be modified so as to adjust the force range that is likely to produce the spring according to the displacement of the pinion 42.
- the same spring can be implemented within several watch mechanisms whose displacement of the sliding pinion differs.
- the first variant of the spring with the same section minimizes the force of the spring generated by the displacement of the rod while ensuring the required holding force in the position of no - correction by means of a pre-arming of the spring, and this in the same volume to disposition.
- This is illustrated by the characteristic force F-displacement Dp of the first variant embodiment of the spring and of a known spring as represented by FIG. 2, measured between a first non-correction position P1 and a second correction position P2. of the pinion 42, which is shown in Figure 3. It is noted that equal space is obtained a greater constancy of the return force with the spring 10 according to the invention. In other words, a lower variation of return force is obtained for a given displacement of the spring 10 according to the invention.
