Embodiment Construction

[0049] Figure 1 to Figure 4 An embodiment of an elastic retaining member 1 for securing a timepiece part 2 on a support element 3 is shown. By way of example, the elastic retaining member 1 may be a collet for fixing a timepiece component 2 , such as a balance spring, to a supporting element 3 , such as a balance shaft.

[0050] In these embodiments, the retaining member 1 may be included in an elastic retaining member-timepiece component assembly 120 in Figure 5 and it is provided arranged in the timepiece movement 110 of the timepiece 100 . Such an assembly 120 may be a single piece made of what is known as a "brittle" material, which is preferably a micromachinable material. Such materials may include silicon, quartz, corundum or ceramics.

[0051] It should be noted that, in this variant of the assembly, only the elastic retaining member 1 can be made of such a so-called "fragile" material, while the timepiece part 2 is made of another material.

[0052] This assembl...

Abstract

An elastic retaining member for attaching a timepiece component to a support element. The invention relates to an elastic retaining member (1) for attaching a timepiece component (2) to a support element (3), the elastic retaining member comprising an opening (5) into which said support element (3) can be inserted, the retaining member (1) comprising rigid arms (6) and elastic arms (7) defined between connecting zones (9), helping to ensure elastic clamping of the support element (3) in the opening (5), and each rigid arm (6) being provided with two flat contact zones (8) of the retaining member (1), which can interact with corresponding convex contact portions (10) of the support element (3).

Description

technical field [0001] The invention relates to an elastic retaining member for securing a timepiece component to a support element. [0002] The invention also relates to an elastic retaining member-timepiece part assembly and the assembly of such an assembly with a support element. [0003] The invention also relates to methods for achieving such assembly. [0004] Furthermore, the invention relates to a timepiece movement comprising at least one such assembly. [0005] Finally, the invention relates to a timepiece comprising such a movement. Background technique [0006] In the prior art, elastic retaining members, such as timepiece collets, are known which, by means of elastic clamping, participate in the assembly of the balance spring on the balance shaft in timepiece movements. [0007] However, in the case of such an assembly, such elastic retaining members have the major disadvantage of requiring complex, lengthy and expensive mounting operations, since the retain...
