Abstract

A system adjusts the angular position of a first toothed wheel set relative to a support on which the first toothed wheel set is mounted such that it can pivot. The adjusting system includes an adjusting member allowing an action to be applied to an angular position of the first toothed wheel set to adjust the angular position of the first toothed wheel set relative to the support. The invention adjusting system can be incorporated into a timepiece.

First claim

The invention claimed is:

1. A system for adjusting an angular position of a first toothed wheel set, the adjusting system comprising:
a support wheel on which the first toothed wheel set is mounted such that it can pivot; and
an adjusting member pivotally mounted on the support wheel, the adjustment member including a toothed sector on a first end that is positioned on a first side of the support wheel and configured to directly contact a tooth of the first toothed wheel set to adjust the angular position of the first toothed wheel set relative to the support wheel,
wherein a second end of the adjusting member protrudes through a second side of the support wheel, the second side being opposite to the first side, to allow an action to the second end to be applied to the angular position of the first toothed wheel set.

2. The adjusting system according to claim 1 , wherein the first toothed wheel set is a pinion, and the pinion is frictionally mounted on the support wheel so as to form a wheel set.

3. The adjusting system according to claim 1 , wherein the support wheel includes two parallel arms and the first toothed wheel set includes a pinion that is frictionally mounted between the two parallel arms.

4. The adjusting system according to claim 1 , wherein the support wheel includes teeth extending around a perimeter of the support wheel.

5. A timepiece comprising:
the adjusting system according to claim 1 .

6. The adjusting system according to claim 1 , wherein teeth of the toothed sector of the adjusting member do not extend around a circumference of the adjusting member.

7. The adjusting system according to claim 1 , wherein the second end of the adjusting member that protrudes through the second side of the support wheel includes a slot that receives a screwdriver to perform the action to the second end to be applied to the angular position of the first toothed wheel set.

8. The adjusting system according to claim 1 , wherein the first toothed wheel set is engaged with a second toothed wheel set that is offset from the adjusting member in an axial direction such that the tooth of the first toothed wheel set, while the tooth is in direct contact with the toothed sector of the adjustment member is also in direct contact with the second toothed wheel set.
