Abstract
A vehicle use-lock actuator is proposed comprising a stationary housing and a reversible drive motor for locking and unlocking successively two remotely positioned locks. In this actuator, the drive motor is mounted within the housing in a hidden position. There is a single control slide for keeping normally respective wire cables at their neutral position for keeping in turn the locks in their locked position. There is provided within the housing a three stage reduction and reversely accelerating gearing between the drive motor and the control slide. The first stage includes a crown gear, while the third stage includes rack teeth which is united rigidly with the control slide.
Claims5
Lock actuator comprising:
- a container housing;
- a drive motor of reversible type and mounted in the container housing;
- a remote ontrol switching unit for operation control of the said drive motor;
- an operation control slide mounted in the container housing and translatable in a reciprocatable manner;
- a first operation-transmitting wire cable leading from said slide to one of a pair of locks;
- a second operation-transmitting wire cable leading from said slide to another of said pair of locks;
- inner, motion-receiving enlarged heads of each of said operation-transmitting wire cables being arranged such that said enlarged heads face one another;
- an at least two stage, reversible reduction gearing arranged between said drive motor and said operation control slide, the latter having three operating positions, one of which is offset relative to a neutral position for pullingly actuating the first wire cable;
- a second one of which is said neutral position and a third one of which is offset oppositely from said one position for pullingly actuating the second wire cable.
