DETAILED DESCRIPTION

The present invention proceeds from the general idea of providing a holding or support assembly of a spiral spring clock for mounting / dismounting the simplest piton.

In a first embodiment shown in FIG. 1 is a schematic view of a holding or supporting assembly 1 of a spiral spring clock according to a first embodiment. This holding assembly 1 comprises a bolt carrier 3 arranged to be fixed to the balance bridge 5 also called cock or base, the latter comprises a longitudinal axis (D). The holding assembly also comprises a pin 9 fixed on a turn of the spiral spring. The bolt carrier 3 is used for fixing the stud to the cock.

In this first embodiment visible in FIGS. 1 and 2, the bolt carrier 3 consists of a retaining plate 32. The rocker arm 5 comprises a stud 31 projecting. This holding plate 32 is a plate pierced by an orifice 34. The holding plate 32 further comprises a deformable beam 35 separating the orifice 34 in a first opening 34a and a second opening 34b.

The first opening 34b is the largest part and is arranged to cooperate with the pad 31. This means that the stud 31 is inserted into the first opening 34a. The second opening 34b is used for the piton 9. Indeed, the pin 9 fits into the second opening 34b.

Advantageously according to the invention, the shape of the pad 31 and that of the first opening 34a are such that they allow, during the rotation of the holding plate relative to said pad, to act on the deformable beam 35 This deformation of said beam makes it possible to narrow the second opening 34b and thus to tighten the peak.

In a first solution visible in FIGS. 3a, 3b and 3c, the first portion 34a is designed to have a perfectly circular shape, the second portion 34b being in the form of a curved groove. In this first solution, the stud 31 is in the form of a piece of non-constant section. More particularly, the stud 31 will be produced so that it is in the form of a substantially circular piece having a central axis C whose area has a distance between the center of the circle and the end of the stud 31 which is larger. which makes it possible to have a distinct zone as visible in FIG. 3a.

This distinct area will be used for clamping the pin 9. Indeed, by rotating the holding plate 32 relative to the pad 31, the distinct area of the stud 31 will come into contact with the deformable beam 35. Given that the first opening 34a is circular, the distinct zone of the stud 31 exerts a stress on this deformable beam 35. This constraint thus deforms the beam 35 which narrows the second opening 34b. This narrowing causes a constraint exerted on the pin 9 to tighten it.

For mounting, it is done by mounting the plate 32 at the cock 5 by inserting the stud 31 in the first opening 34a of the holding plate 32. The holding plate 32 can be mounted in its position angular definitive or not. The stud 31 may be provided with a peripheral groove preventing the holding plate 32 from being detached. In the case where the holding plate 32 is mounted in its final angular position, the holding plate 32 will be rotated by a certain angle in the clockwise or counterclockwise direction so that the distinct zone is no longer in contact with the deformable beam. 35. The stress applied by this distinct zone is thus removed and the second opening 34b resumes its rest size as shown in FIG. 3b.

The pin 9 is then placed in the second opening 34b and the holding plate 32 is rotated relative to the stud 31 to narrow the second opening 34b and tighten the pin 9 on the holding plate 32 as visible in FIG. fig. 3c.

The stud 31 may be designed as a circular piece provided with a projecting portion or an ovoid-shaped piece.

In a second solution visible in FIGS. 4 and 5, the first opening 34a is designed to have an ellipse shape, the second opening 34b being in the form of a curved groove. Such an ellipse shape makes it possible to have an elliptical stud 31. Such an ellipse has a main axis called focal axis passing through the foci and a secondary axis perpendicular to the focal axis and passing to the center of the segment formed by the two focal points of said ellipse. In this second solution, the stud 31 is in the form of a piece of section identical to that of the first opening 34a as shown in FIG. 4.

However, the stud 31 is arranged so that its main axis extends parallel to the longitudinal axis of the cock (5) as shown in FIG. 4. Therefore, when mounting the holding plate 32, the stud 31 is inserted into the first opening 34a. The result is that the holding plate 32 is in a position angularly offset relative to an alignment with the longitudinal axis of the cock 5. This is because when the plate 32 and the cock 5 are perfectly aligned, the stud 31 and the first opening 34a of the plate 32, which have an identical shape, are not confused and are angularly offset.

During the rotation of the holding plate 32 to effect the clamping of the pin 9 inserted in the second opening 34b, one of the two poles that is to say one of the two furthest zones from the center of the stud 31 is in contact with the deformable beam 35. This deformable beam 35 is then subjected to a stress on the part of the pad 31 causing the deformation of said beam 35. This deformation of said beam 35 causes a narrowing of the second opening 34b and therefore the appearance a constraint on the pin 9 which clamps as shown in fig. 5.

In a second embodiment shown in FIG. 6, the bolt carrier 3 consists of a holding plate 302 and a stud 301. The holding plate and the cock are here only one piece in which an orifice 304 is made. The stud 301 is here a free piece cooperating with said holding plate.

The holding plate 302 further comprises a deformable beam 305 separating the orifice 304 into a first opening 304a and a second opening 304b. The first opening 304b is the largest part and is arranged to cooperate with the stud 301. This means that the stud 301 is inserted into the first opening 304a. The second opening 304b is used for the piton 9. Indeed, the stud 9 fits into the second opening 304b.

Advantageously according to the invention, the shape of the stud 302 and that of the first opening 304a are such that they allow, during rotation of the stud 302 relative to the holding plate, to act on the deformable beam. 305. This deformation of said beam makes it possible to narrow the second opening 34b and thus to tighten the stud 9.

In a first solution visible in FIGS. 7a and 7b, the first opening 304a is designed to have a perfectly circular shape, the second opening 304b being in the form of a curved groove. In this first solution, the stud 301 is in the form of a piece of non-constant section. More particularly, the stud 301 will be made so that it is in the form of a substantially circular piece whose area has a distance between the center of the circle and the end of the stud 301, which makes it possible to have a separate area.

This distinct area will be used for clamping the pin 9. Indeed, by rotating the stud 301 relative to the holding plate 302, the separate area of the stud 301 will come into contact with the deformable beam 305. Being Since the first opening 304a is circular, the distinct zone of the stud 301 exerts a stress on this deformable beam 305. This constraint thus deforms the beam 305 which narrows the second opening 304b. This narrowing causes a constraint exerted on the pin 9 to tighten it.

For mounting, it is done by mounting the stud 301 at the cock 5 by inserting it into the first opening 304a of the holding plate 302. The stud 301 can be mounted in its final angular position or not. In the case where the stud 301 is mounted in its final angular position, the stud 301 will be rotated by a certain angle in the clockwise or counterclockwise direction so that the distinct zone is no longer in contact with the deformable beam 305. The constraint applied by this distinct zone is removed and the second opening 304b resumes its rest size allowing mounting of the peak 9.

The stud 9 is then placed in the second opening 304b and the stud 301 is rotated relative to the holding plate 302 to narrow the second opening 304b and tighten the stud 9 on the retaining plate 302.

The stud 301 may be designed as a circular piece provided with a projecting opening or a piece of ovoid shape.

It is possible to adjust the angular position of the pin 9 by sliding it in the second opening 304b.

In a second solution visible in FIGS. 8a, 8b and 8c, the first opening 304a is designed to have a perfectly ovoidal shape, the second opening 304b being in the form of a curved groove. Such an ovoid shape makes it possible to have a stud 301 whose external dimensions in the X-Y plane are different. The length of the pad 301 is larger than its width. In this second solution, the stud 301 is in the form of a piece of section identical to that of the first opening.

However, the first opening 304a is arranged so that its length extends perpendicularly to the longitudinal axis of the cock (5). Therefore, when mounting the holding plate 302, the stud 301 is inserted into the first opening. The result is that the longitudinal axis of the stud 301 is in a position angularly offset relative to an alignment with the longitudinal axis of the cock 5.

During the rotation of the stud 301 to effect the clamping of the stud inserted in the second opening, one of the two poles, that is to say one of the two furthest regions from the center of the stud 301 comes into contact with the Deformable beam 305. This deformable beam 305 is then subjected to a constraint on the part of the stud 301 causing its deformation. This deformation causes a narrowing of the second opening 304b and therefore the appearance of a constraint on the pin 9 to tighten it.

In a variant shown in FIG. 9, the holding plate 302 is a plate which is fixed on the cock 5. The cock 5 also comprises a through hole or not 500 identical to the first opening 304a of the holding plate 302. When the holding plate 302 is fixed at cock 5, the two openings 304a, 500 merge with each other. This variant advantageously makes it possible to modify the angular position of the holding plate relative to that of the cock and thus allow a better positioning of the pin.

For the rotational mounting of the pad 301 relative to the holding plate 302 or the holding plate 32 relative to the pad 31, a male interface 700 and a female interface 702 are arranged. The interface maie 700 and the female interface 702 thus cooperate together so as to allow the mobile part to be mounted at the rooster 5 by a rotational movement.

According to a first alternative embodiment, the rotational mounting is a bayonet mount. In the case of FIG. 13, the stud extends from the cock 4 and the holding plate 32 is mounted to the pad 31. The female interface 702 is arranged on the pad 31. This female interface 702 consists in that the stud 31 has in its thickness at least one cavity 702a. This cavity 702a is formed by a clearance 702b parallel to said central axis of the stud 31 and opening with respect to the lower surface of the stud 31, and secant with said first clearance and opposite the upper surface 31a, a blind groove 702c . This groove 702c is used for bayonet immobilization of the holding plate 32.

The interface maie 700, located at the first opening 34a, consists of at least one projecting portion 701. This projecting portion 701 is located on the edge of the first opening 34a. This projecting portion 701 is arranged to cooperate with the female interface 702 of the stud.

The holding plate 32 is mounted at the stud 31 so that the projections 701 of the holding plate 32 can be introduced into the clearance 702b of said stud 31. The stud can then be introduced into the first opening . When the stud reaches the stop, the projecting parts must be opposite the grooves. Therefore, a rotational movement is made to introduce the protrusions into said grooves and fix said stud to the cock.

According to a second alternative, the rotational mounting is a screw mounting. For this, the female interface and the interface maie both consist of a thread.

In a first variant of the two embodiments shown in FIGS. 10 and 11, the stud 31, 301 comprises, at its lower face 31a, 301a, a recess 400. This recess allows to insert a shock absorber system 402. The latter can be in a conventional form c ' that is to say a kitten in which a pierced stone and a stone against pivot are arranged or in the form of a single stone 404. This single stone 404 is provided with a recess for cooperating with the balance shaft and may be force-fitted into the recess 400 via an elastic ring 406. The shock absorbing system may also be in the form of a pellet provided with elastic arms. This variant makes it possible to have a centering between the peak and the pivot of the balance shaft which will cooperate with said shock absorber system. This variant can be pushed further by imagining that the stud 301 is itself a shock absorber system.

This shock absorbing system is in the form of a kitten in which a pierced stone and a counter-pivot stone are arranged.

In a second variant, visible in FIG. 12, wherein the stud 301 is a free piece and provided with a shock absorbing system 402, the stud 301 is mounted adjustable in height. For this, a thread 600 is arranged at the first opening 304a in which the stud 301 is inserted. The stud 301 then comprises a thread 602 on its outer wall 301b to cooperate with the thread 600 of the holding plate 302. It is therefore possible to adjust the height position of the shock absorber system by making more or less turns with the stud. It will then be understood that a preliminary step in mounting the stud is a setting step in which the stud is inserted into the first opening of the holding plate and then rotated to adjust the height of the shock absorbing system. The next step is then the step of setting up the peak and tightening this peak.

In a third variant of the first and second embodiments, adjustment means 800 are provided for the angular adjustment of the holding plate to change the angular position of said support plate relative to the rooster while maintaining a good tightening the bolt.

In the case of the second embodiment in which the stud 301 is a piece which is attached to the base and that the holding plate 302 is fixed to the cock 5,

The adjustment means 800 thus comprise engagement means 801 arranged on the face of the holding plate facing the cock and a plurality of receptacles 802 arranged on the face of the cock opposite the holding plate as visible in fig. 14. For example, the engagement means 801 comprise at least one tube 803 projecting from the face of the holding plate facing the cock while the plurality of receptacles comprises a plurality of holes in which the tubes can be inserted. The fact of having a plurality of tubes 803 makes it possible to maintain even in case of breakage of one of the tubes 803.

[0064] Preferably, the plurality of tubes and the plurality of holes are arranged in a circle. This arrangement has the advantage of allowing angularly change the position of the holding plate relative to the cock and lock this angular position. Once the angular position defined and locked, the steps of setting the stud and clamping the stud to the holding plate can be operated.

Therefore, as the stud is an insert, it suffices simply to insert said stud in the first opening of the holding plate and in the opening of the cock and to rotate it to act on the beam deformable from the holding plate to tighten the piton.

In the case of the first embodiment shown in FIG. 17, angular adjustment means are provided. These adjustment means 800 comprise a toothed wheel 810 arranged on the balance bridge 5. This toothed wheel 810 is mounted on an axis. This toothed wheel 810 is arranged to cooperate with a toothing 812 arranged on the holding plate. More particularly, this toothing 812 is arranged on the outer wall 32a of the holding plate 32.

This wheel 810 includes a slot 814 so that a tool such as a flat-head screwdriver and then be used to act on the toothed wheel 810.

Thus, to change the angular position of the pin 9, a person engages the flat head of the screwdriver in the slot 814 of the toothed wheel and rotates the toothed wheel 810. This toothed wheel 810 meshes with the toothing 812 of the holding plate causing the rotation of the latter.

It may be envisaged that the adjustment means 800 comprise a second notch 822 arranged on the holding plate and a first notch 820 arranged at the pivot point 5 as shown in FIG. 18. These notches are facing each other so that it is possible to place the flat head of a screwdriver in the two notches. This arrangement allows, by pivoting the screwdriver 824 on itself, to rotate the holding plate. Angular adjustment means of the simple and inexpensive holding plate are thus obtained.

Furthermore, in another variant, it will be understood that the stud 31 and the holding plate 32 or the holding plate 302 and the stud 301 are arranged on the underside of the cock 5, that is to say at the level of the face lying next to the spiral balance.

In another variant visible in FIGS. 15a, 15b, 16a, 16b, the orifice 34, 304 of the holding plate 32 as visible in FIGS. 15a, 15b or the balance bridge 5 as visible in FIGS. 16a, 16b is separated into a first opening and a second opening by a deformable arm 35a, 305a having one end connected to the wall of the orifice 34, 304 and a free end. The wall of the orifice 34, 304 further comprises an extension 35b, 305b whose shape is arbitrary. This extension allows, when mounting the stud, to have the resilient arm pressing the stud against the wall of the second opening 34b ', 304b' and against the wall of the extension to block said pin as visible in FIGS. 15b and 16b.

As such, it may be provided a variant in which the deformable arm comprises a boss or projection 35a 'as visible in FIGS. 19a, 19b. This hump or projection cooperates with the stud 31. Indeed, it is cleverly provided that the stud 31 is circular but has a flat 31a. The elastic arm 35a is then arranged so that, when facing the flat, said arm 35a is released so that the bolt can be easily placed. When the holding plate 32 is rotated to lock the pin 9, the bump of the resilient arm 35a remains in contact with the wall of the stud 31 so that the thickness variation of the stud 31 between the plate and the rest of its periphery causes a constraint on the elastic arm 35a. This constraint tends to bring the elastic arm closer to the wall of the orifice 34, 304. The pin is thus held in place by said elastic arm. A notch 31b on said pad 31 may be envisaged to block the angular position of the holding plate 32. This configuration also makes it possible to use the hump as a marker to visualize the angular position of the bolt carrier. It will be understood that various modifications and / or improvements and / or combinations obvious to those skilled in the art can be made to the various embodiments of the invention set out above without departing from the scope of the invention defined by the appended claims.

Furthermore, it can be provided that the angular adjustment of the holding plate on the cock is done by providing two oblong holes at said holding plate. These two oblong holes allow the fixation of the support plate on the cock while allowing a degree of freedom in the rotation. Preferably, the oblong holes will be made so that the holding plate can rotate around the stud.

It may also be provided that the holding plate 32 is further provided with at least one notch 32a at its periphery as shown in FIGS. 19a and 19b. Such a notch simply allows to use a screwdriver type tool or tweezers to rotate the holding plate. In the case of the use of tweezers, two diametrically opposed notches can be arranged.

Similarly, it may be provided that the pad 301 serving as a shock absorber is used as a Z stop for retaining the stud holder during shocks.
