Abstract: An actuator for a parking lock system of a vehicle transmission gearbox. The actuator includes an electric motor having a casing in which a stator and a rotor are housed, the rotor being connected to a rotary shaft, the rotation of said shaft being guided by at least two guide elements. The actuator further includes a mechanism with a wheel and a worm situated on the drive shaft. At least two rings are mounted on the drive shaft so that, under the effect of an axial force generated by the wheel on the worm, at least one of the rings abuts against the casing or against at least one of the guide elements in order to generate friction torque, thus placing the actuator in a wedged condition.

Abstract: A bed leg with a caster, equipped with a braking mechanism that allows the bed to be immobilized is provided. The bed leg comprises a housing, which houses a caster, an actuating mechanism installed in the housing, a pedal joined to a lever and a braking pad mounted on the lower part of the actuating mechanism.
