Abstract
The disclosure provides a lock with a radially extending cam that can be pivoted electrically or manually by a key. The lock resides in a housing for ease of manufacture and reduction of space, for use, as an example, as a replacement or retrofit for an existing manual cam lock. The cam extends transversely to a first axis and is manually rotatable by a key about the first axis. The cam is also rotatable about a second axis parallel to the first axis by an electrical signal to a motor or a linear actuator connected to a cam mechanism body.
Claims13
A pivoting electrical cam lock comprising,
- a base with a cylindrical open bore defining a first axis, a rotating mechanical lock in the bore having a keyway at one end and an actuator at the opposite end, the mechanical lock adapted so that when a proper key is inserted into the keyway and rotated, the mechanical lock and actuator rotate with the key,
- a cap fixed to the actuator adapted to rotate about the first axis with the actuator and mechanical lock, the cap having a cylindrical second bore defining a second axis parallel to the first axis,
- a cam radially extending from the cap and adapted to rotate about the first axis with the cap upon rotation of the proper key,
- a linear actuator secured to the cap, the linear actuator adapted to move an arm transversely to the second axis in response to an electrical signal,
- a cam mechanism body with a first end contacting the arm and a second end contacting the cam and adapted so that the cam pivots about the second axis in response to linear movement of the arm in response to the electrical signal.
