Embodiment Construction

[0046] The invention relates to a timepiece display mechanism 100 comprising at least one display 10 comprising an axis 3 and comprising at least one main plate 101 and / or bridge 102 carrying at least one guide means 1 , the guide means 1 For carrying and guiding such a shaft 3 . The timepiece display 10 is in particular and in a non-limiting manner hands, discs, etc., and comprises or is mounted on the shaft 3 .

[0047] The guide 1 comprises a slot 2 arranged for the passage of the axis 3 of the display 10 or arranged to carry the display 10 directly. The guide device 1 comprises at least one guide bearing 4 for guiding such a shaft 3 around the axis D.

[0048] According to the invention, the at least one guide bearing 4 comprises, on the first side of the axis D, a support surface 5 comprising a V-shape or a pad or the like, and this support surface 5 is arranged to orient the axis of rotation of the shaft 3 The center is on the bisecting plane P of the support surface 5...

Abstract

A timepiece display mechanism (100) comprising at least one display (10) comprising a shaft (3), and comprising at least one main cleat (101) and / or cleat (102) carrying at least one guide device (1) for carrying and guiding the shaft (3) about an axis (D), the guide device (1) comprising, on a first side of said axis (D), a support surface (5) comprising a V-shape or a pad, according to the invention, the guide device (1) comprises, on an opposite second side, at least one holding element (6), which is substantially diametrically opposite to the support surface (5), and which is arranged on the support surface (5), said holding element (6) being symmetrical with respect to a bisecting plane (P) passing through the axis (D) such that the axis of the shaft (3) is centered on the bisecting plane (P) of the support surface (5). All said retaining elements (6) exert a resultant elastic restoring force on the shaft (3) towards said axis (D) and prevent the shaft (3) from radially exiting from any of the guide bearings (4), which are platforms having two parallel faces.

Description

technical field [0001] The present invention relates to a timepiece display mechanism comprising at least one display comprising a shaft and comprising at least one platine and / or pont carrying at least one guiding means to carry and guide the axis. [0002] The invention also relates to a timepiece comprising at least one such timepiece display mechanism and / or at least one such guide means. [0003] The present invention relates to the field of timepiece display mechanisms. Background technique [0004] In a watch movement, the hours, minutes and seconds are usually displayed by hands. These hands must not touch each other, nor the dial, movement parts or glass. [0005] Several factors affect safety between pointers: [0006] - rocking of the bearing shaft of each pointer; [0007] - the inclination of the shaft relative to the main plate or plate due to imperfections in the position, roundness and shape of the guide; [0008] - the inclination of the shaft due to p...
