Description

Technical field of the invention

The present invention relates to the field of watchmaking. It relates, more particularly, to fixing devices for adjusting the swing of the balance.

Technology background

[0002] Adjusting the pendulum stroke is essential for the proper functioning of a mechanical movement. The positioning and locking of the stud holder and the balance shock absorber are just as important. In the majority of mechanical movements, the shock absorber is driven into the balance bridge, itself locking the stud holder.

To adjust these two elements, it is necessary to exert a significant force on these elements which is tedious and can lead to degradation of said elements and their environment.

Summary of the invention

The present invention relates to a fixing device for adjusting the movement of a balance, preferably for adjusting the movement of said balance; said at least one fastening device comprising at least one stud holder, at least one: bearing housing; said at least one bearing body being configured to move relative to said at least one stud carrier; supporting body; said at least one support member being configured to press said at least one bearing body against said at least one stud carrier; and, retaining member; said at least one holding member being configured to hold said at least one support member pressed against said at least one bearing body so as to fix the adjustment of said motion of said balance.

[0005] Thanks to this arrangement, said fixing device makes it possible to adjust said at least one stud holder and the positioning of said at least one bearing body without having to exert significant forces, and makes it possible to guarantee the functionality of the movement and good resistance to shocks.

According to one embodiment, said fixing device comprises at least one balance bridge configured to cooperate with said at least one holding member.

[0007] Thanks to this arrangement, said at least one retaining member can cooperate with said at least one balance bridge.

[0008]According to one embodiment, said at least one bearing body is configured to be between said at least one eyebolt carrier and said at least one bearing member.

[0009] Thanks to this arrangement, the adjustment of said at least one bearing body is maintained thanks to said at least one stud carrier and to said at least one support member.

[0010]According to one embodiment, said at least one bearing member comprises a first bearing surface configured to press said at least one bearing body against said at least one eyebolt carrier and at least one second bearing surface. support configured to be in contact with said at least one holding member.

[0011] Thanks to this arrangement, said at least one support member transmits the force of said at least one holding member to said at least one bearing body.

[0012]According to one embodiment, said at least one bearing body comprises a thread or a thread disposed on the outer periphery of said at least one bearing body and said at least one eyebolt carrier comprises a thread or a thread disposed on the inner periphery of said at least one eyebolt holder.

[0013] Thanks to this arrangement, said at least one bearing body can be screwed to said at least one stud holder.

Brief description of figures

The invention will be described below in more detail with the aid of the accompanying drawing, given by way of non-limiting example, in which FIG. 1 shows a balance swing adjustment fixing device.

Detailed description of the invention

[0015] Adjusting the pendulum stroke is essential for the proper functioning of a mechanical movement. To this end, the applicant proposes a fixing device 100 for the rebound adjustment of a pendulum 200. Said at least one fixing device 100 comprising at least one stud carrier 110, at least one bearing body 120, at least one support member 130 and at least one holding member 140.

As illustrated in Figure 1, said at least one bearing120est body configured to move relative to said at least one eyebolt holder110par through a thread-tapping.

[0017] Indeed, according to the embodiments, said at least one bearing120 body may comprise an internal thread or a thread arranged on the outer periphery of said at least one bearing120 body. Said at least one stud carrier 110, for its part, may comprise a thread or an internal thread arranged on the internal periphery of said at least one stud carrier 110 so that said at least one bearing body 120 can be screwed to said at least one stud carrier 110 and so adjust the movement of said pendulum200.

[0018] Said at least one support member 130 is configured to press said at least one bearing body 120 against said at least one stud holder 110 and said at least one holding member 140 allows said at least one support member 130 to be held against said at least one bearing body 120 so as to fix the adjustment of said movement of said balance wheel 200 and therefore the positioning of said at least one bearing body 120 without having to exert significant forces while guaranteeing the functionality of the movement and good resistance during shocks. In other words, said at least one bearing body 120 can be included between said at least one stud carrier 110 and said at least one support member 130 so as to be held by said at least one stud carrier 110 and said at least one support member. support130.

[0019] This support can be improved by means of support surfaces present on said at least one support member130. Indeed, said at least one bearing member 130 comprises a first bearing surface 131 enabling said at least one bearing body 120 to be pressed against said at least one eyebolt carrier 110 and at least one second bearing surface transmitting the holding force exerted by said at least one holding member140au said at least one bearing body120.

[0020] The whole thing, that is to say said at least one stud holder 110, said at least one bearing body 120, said at least one support member 130 and said at least one holding member 140, rests on at least one balance bridge 150 configured to cooperate with said at least one holding member140.
