Abstract
The invention relates to a method (19, 19′, 39, 39′, 59, 59′) of assembling a part (5, 5′, 25, 25′, 45, 45′) in the aperture (18, 18′, 38, 38′, 58, 58′) of a component (3, 3′, 23, 23′, 43, 43′). According to the invention, the assembly system (19, 19′, 39, 39′, 59, 59′) includes a system (1, 1′, 21, 21′, 41, 41′) of securing the component (3, 3′, 23, 23′, 43, 43′) and the part (5, 5′, 25, 25′, 45, 45′) to each other, which includes at least one pawl device (11, 11′, 31, 31′, 51, 51′) intended to make the component (3, 3′, 23, 23′, 43, 43′) and the part (5, 5′, 25, 25′, 45, 45′) move integrally with each other. The invention concerns the field of timepieces.
Claims21
A timepiece comprising a system for assembling a part in an aperture of a component, the system for assembling comprising a system for securing the component and the part to each other in a same plane, the system for securing comprising at least one pawl device configured to lock the component and the part such that, once the component and the part are locked, the component and the part are locked in a final assembled configuration and move integrally with each other,
- wherein the locking of the component and the part prevents the component and the part from slipping relative to one another in all directions once the component and the part are locked,
- wherein the system for securing does not comprise a clutch mechanism, and
- wherein, once the component and the part are locked, the component and the part are unable to be unlocked without destroying the system.
A timepiece comprising a system for assembling a part in an aperture of a component, the system for assembling comprising a system for securing the component and the part to each other on a same plane, the system for securing comprising at least one pawl device configured to lock the component and the at least one pawl device such that, once the component and the at least one pawl device are locked, the component and the part are locked in a final assembled configuration and rotate substantially integral with each other along the same plane to prevent relative movement between the component and the part,
- wherein the locking of the component and the part prevents the component and the part from slipping relative to one another in all directions once the component and the at least one pawl device are locked,
- wherein the system for securing does not comprise a clutch mechanism, and
- wherein, once the component and the part are locked, the component and the part are unable to be unlocked without destroying the system.
A timepiece comprising a system for assembling a part in an aperture of a component, the system for assembling comprising a system for securing the component and the part to each other in a same plane, the system for securing comprising at least one pawl device configured to lock the component and the part such that, once the component and the part are locked, the component and the part are locked in a final assembled configuration and move integrally with each other,
- wherein the locking of the component and the part prevents the component and the part from slipping relative to one another in all directions once the component and the part are locked,
- wherein the system for securing does not comprise a clutch mechanism,
- wherein the part has at least one stop and at least one mortise and at least one ramp connecting the at least one stop with the at least one mortise and the component has the at least one pawl and a tenon on each of the at least one pawl, and
- wherein the part and the component are rotatable relative to one another until the tenon of the component is stopped by the stop of the part and then they rotate together, and wherein the part and the component are rotatable relative to one another until the tenon of the component is locked in the mortise of the part to move integrally with each other.
