Claim:
A clutch mechanism for locks, characterized in that, in relation to the interior and exterior sides of a lock installed in a door, the mechanism is composed of an interior axis ( 1 ), an exterior axis ( 2 ), a static body ( 3 ), a set of a radial pin ( 4 ) and radial catch ( 5 ), and a radial actuator ( 6 ); in which: said interior axis ( 1 ), exterior axis ( 2 ) and static body ( 3 ) compose a coaxial assembly in which the exterior axis ( 2 ) penetrates with a rotational adjustment within the interior axis ( 1 ) when both the interior ( 1 ) and exterior ( 2 ) axes are installed with a rotational adjustment in the static body ( 3 ), said set of radial pin ( 4 ) and radial catch ( 5 ) is installed with a movable adjustment between one said actuator ( 6 ) which is in contact with the radial pin ( 4 ) and a radial compression spring ( 7 ) which acts between the radial catch ( 5 ) and the base of the housing ( 2 a ) of the exterior axis ( 2 ), whose radial pin ( 4 ) and radial catch ( 5 ) are dimensioned in combination so that, in an exclusive manner, one or the other is able to remain within the circumference of the exterior diameter of the exterior axis ( 2 ) and the circumference of the interior diameter of the interior axis ( 1 ), and said radial actuator ( 6 ) is composed of a curved plate ( 6 a ) and by at least one rod ( 6 b ), whose curved plate ( 6 a ) is located in an annular depression ( 8 ) defined between said interior axis ( 1 ) and static body ( 3 ), where this curved plate ( 6 a ) extends in a circumferential arc which contains the angular sector corresponding to the operative rotational transit of said interior axis ( 1 ) to either side of a central position, and whose rod ( 6 b ) of the radial actuator ( 6 ) is installed with a movable adjustment in said static body ( 3 ) and, when it is the only one, this rod ( 6 b ) is in the center of said curved plate ( 6 a ) and aligned with said radial pin ( 4 ) and radial catch ( 5 ) in said resting position.
