Abstract:
Clutch device for locks, characterized in that, with relation to the interior and exterior sides of a lock installed in a door, the device consists of an interior axis (1), an exterior axis (2), a frame or static body (3), an elastic element (4), a radial trigger (5), a radial trigger lock (6) having a tip and a tail end, and a radial actuator (7); wherein: said interior axis (1), exterior axis (2) and static body (3) comprise a coaxial assembly in which the exterior axis (2) penetrates, with a rotary adjustment, into an axial cavity (8) of the interior axis (1) while both axes (1, 2) are assembled with a rotary adjustment within the static body (3), said elastic element (4) is in a fixed relative position with respect to the static body (3) and in an annular housing (9) which is defined between said static body (3) and the interior axis (1), said radial trigger (5) is lodged in a movable manner within the interior axis (1) and has a length equal to the difference between the exterior diameter of the exterior axis (2) and the interior diameter of the static body (3), said radial trigger lock (6) is installed within the exterior axis (2) with its tip in the exterior diameter of this exterior axis (2) and with its tail end placed against one end of a radial compression spring (10) which has its other end at the base of a radial enclosure (11), said radial actuator (7) is installed by means of the static body (3) with the possibility of operative sliding between respective inhibited and extended positions in which one end of the actuator, which is directed toward the inside of the device, remains situated, respectively, in the exterior diameter of the interior axis (1) and in a location intermediate to the exterior and interior diameters of this interior axis (1); and wherein said radial actuator (7) tends to remain axially aligned with said radial trigger (5) and trigger lock (6) for an initial rotary position in which the clutch device is at rest.
