Problems solved by technology

However, the disadvantage of this solution is that in order to machine the cam path in the cylindrical part of the control arbor, the diameter of the cylindrical part of the control arbor must be relatively large, which makes the use of such a control arbor very difficult, or even impossible. Possibly, especially in the field of watches, where it is not desirable to machine large diameter holes in the case middle, especially due to the thickness of the case middle

Embodiment Construction

[0050] The invention stems from the general inventive idea of ​​transferring the position determining mechanism of a control stem for controlling at least two electronic and / or mechanical functions of a portable object of small size, such as a timepiece, from the control stem to the Plates that are machined separately from the control arbor described above. By doing so, it is possible to reduce the size of the control stem and thus the thickness of the case middle of a portable object such as a timepiece. This result is achieved due to the fact that, instead of being constructed directly on the control arbor, the determining mechanism, typically in the form of two cam paths cooperating with elastic members, is produced on a thin plate which forms an independent part of the control arbor. part and is mechanically coupled to the control arbor. Since the control arbor is free of its determining mechanism, its diameter can be reduced, and the small thickness of the inventive posi...

Abstract

The invention concerns a device for controlling at least two electronic and / or mechanical functions of a portable object of small dimensions, this device including a control stem (4) which is axiallymovable between at least a first and a second position, this control stem (4) being provided at a first end (6) with an actuation member (8), and being provided towards a second end (10) with a position indexing plate (58) arranged to cooperate with an elastic member (80) in order to match each of the first and second positions of the control stem (4) with one of the mechanical or electronic functions.

Description

technical field [0001] The invention relates to a device for controlling at least two electronic and / or mechanical functions of a portable object of small size. More specifically, the invention relates to a device comprising a control stem provided with mechanical position determination / idexing means that make it possible to align each electronic or mechanical function with the control stem different positions of the axes. Background technique [0002] The invention relates to the field of control arbors mounted to small-sized portable objects, such as timepieces, and arranged to control one or more electronic and / or mechanical functions of such objects. [0003] In a very simplified manner, this type of control stem consists of a cylindrical portion, the length of which is significantly greater than its diameter, and the crown is fixed to the end of the cylindrical portion outside the portable object, enabling the user to actuate the control Arbor and adjust the electroni...
