Embodiment Construction

[0022] The invention stems from the general inventive idea of ​​inserting, in a break-off mechanism for a timepiece winding crown, a stop between the elastically deformable element and the bottom of the crown, in order to prevent a gap between these two elements. any surface contact occurs. Thus, when the crown is pressed axially in the direction of the center of the timepiece movement, any secondary moment is prevented, which means that the moment of disengagement of the elastically deformable element from the rigid drive ring does not have to be changed in order to protect the timepiece movement, in particular It is the mainspring.

[0023] The structure of the winding crown according to the invention, indicated as a whole by the general reference numeral 40, is the same as above with reference to figure 1 The structure described is very similar. For a complete description of this crown, reference may be made to European Patent Application No. 1586960 in the name of the ap...

Abstract

Winding crown for a timepiece, said crown (40) including a bottom (42) and a skirt (44), which delimits an inner volume housing at least one elastically deformable element, the crown (40) being characterized in that a stop member is inserted between the elastically deformable element (50) and the bottom (42) of the crown (40) to prevent any surface contact between said elastically deformable element (50) and said bottom (42).

Description

technical field [0001] The invention relates to winding crowns for timepieces. More specifically, the invention relates to crowns of this type protected against any secondary or parasitic resisting moments. Background technique [0002] A timepiece crown of the type mentioned in the opening paragraph is known from European Patent Application No. 1586960 in the name of the applicant. attached here figure 1 Such a crown is shown in cross-section in . This crown, indicated as a whole by the general reference numeral 1 , has an axis of rotational symmetry X1 and is hollow so as to define a cavity housing the various elements of the disconnecting mechanism. These elements include in particular a hollow support element 2 , whose dimensions are adapted to the dimensions of the hollow inner cavity of crown 1 , and which is closed on one side by a bottom 4 . [0003] Secondly, there are two identical springs 6 for arrangement against the bottom 4 of the hollow support element 2 ....
