A shock absorbing coupling device for a timepiece, includes a coupling wheel (2) able to take a coupled position and an uncoupled position, a coupling member (1) bearing the coupling wheel and a coupling cam (6) engaging with the coupling member (1) to define the coupled position and uncoupled position of the coupling wheel (2). The device also includes a locking member (12) rigidly attached to the coupling cam (6) and an intermediate member (9) controlled by the coupling member (1). The intermediate member (9) is intended to engage with the coupling member (1) and the locking member (12) to prevent or limit the movement of the coupling member (1) under the effect of a shock when the coupling wheel (2) is in the coupled position, to thus avoid the coupling wheel (2) leaving the coupled position.
A device for a timepiece comprising a movable element (1) that can assume at least two specified positions and a coupling cam (6) working with said movable element (1) to define said at least two specified positions, wherein the device also comprises a hook wheel (12) that is integral with the coupling cam (6) and an intermediate element (9) controlled by the movable element (1) and designed to work with the hook wheel (12) to prevent or to limit the movement of said movable element (1) under the action of a shock when the movable element (1) is in one of its specified positions, thus preventing said movable element (1) from leaving its specified position, wherein the movable element (1) carries a coupling wheel (2) that can assume a coupled position and an uncoupled position, and wherein the coupling cam works with the movable element (1) to define the coupled position and the uncoupled position of the coupling wheel (2).
A device for a timepiece comprising a movable element (1) that can assume at least two specified positions and a control cam (6) working with said movable element (1) to define said at least two specified positions, wherein the device also comprises a locking element (12) that is integral with the control cam (6) and an intermediate element (9) controlled by the movable element (1) and designed to work with the locking element (12) to prevent or to limit the movement of said movable element (1) under the action of a shock when the movable element (1) is in one of its specified positions, thus preventing said movable element (1) from leaving its specified position, and wherein the intermediate element is arranged so that its position can be adjusted in relation to the position of the movable element (1).
A device for a timepiece comprising a movable element (1) that can assume at least two specified positions and a control cam (6) working with said movable element (1) to define said at least two specified positions, wherein the device also comprises a locking element (12) that is integral with the control cam (6) and an intermediate element (9) controlled by the movable element (1) and designed to work with the locking element (12) to prevent or to limit the movement of said movable element (1) under the action of a shock when the movable element (1) is in one of its specified positions, thus preventing said movable element (1) from leaving its specified position, wherein the movable element (1) carries a coupling wheel (2) that can assume a coupled position and an uncoupled position, and wherein the intermediate element (9) is guided by two guide pins (16) and is attached to the movable element (1) by at least one holding screw (13) that passes through an opening (15) of said movable element (1) in such a way that the coupled position of the coupling wheel (2) can be adjusted.
