Embodiment Construction

[0022] The present invention is derived from the following general inventive idea, that is, in the breaking mechanism for the winding crown of a timepiece, a stopper is inserted between the elastically deformable element and the bottom of the crown to prevent the gap between the two elements Any surface contact has occurred. Therefore, when the crown is pressed axially in the direction of the center of the watch movement, any secondary moments are prevented, which means that it is not necessary to change the moment when the elastically deformable element is released from the rigid drive ring to protect the watch movement, especially It is the mainspring.

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

Abstract

The invention discloses a winding crown for a timepiece, said crown (40) comprising a bottom (42) and a skirt (44), which defines a housing for at least one elastically deformable element. Internal volume, said crown (40) is characterized in that a stop is inserted between the elastically deformable element (50) and the bottom (42) of the crown (40) to prevent said elastically deformable element ( 50) any surface contact with said bottom (42).

Description

Technical field [0001] The present invention relates to winding crowns for timepieces. More specifically, the present invention relates to this type of crown that is protected from any secondary or parasitic resistive moments. Background technique [0002] The type of timepiece crown mentioned in the opening section is known from European Patent Application No. 1586960 in the name of the applicant. Attached here figure 1 This crown is shown in cross section. This crown, indicated as a whole by the general reference numeral 1, has an axis of rotational symmetry X1 and is hollow, thereby defining a cavity that accommodates 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 the crown 1 and which are closed by a bottom 4 on one side. [0003] Secondly, there are two identical springs 6 for placement against the bottom 4 of the hollow support elem...
