Abstract
The present invention is directed to a latch actuating device that includes a handle and a base. The handle has a cavity that houses a lockset, a drive cam, and a driven cam. The drive cam has a protrusion that is removably received within a locking receptacle in the base so as to permit and restrict rotation of the handle with respect to the base. The drive cam causes the driven cam to translate along a rotational axis of the drive cam when the drive cam is rotated by the lockset, thus effectuating the insertion and retraction of the protrusion with respect to the locking receptacle.
Claims20
A latch actuating device comprising:
- a handle;
- a lockset housed within the handle, the lockset having a rotatable tail;
- a drive cam housed within the handle, the drive cam configured to receive and be rotated by the tail;
- a driven cam housed within the handle, the driven cam having a protrusion;
- a biasing element that biases the driven cam toward the drive cam;
- and
- a base that receives a portion of the handle such that the handle is rotatable with respect to the base, the base having a locking receptacle for receiving the protrusion;
- wherein the driven cam translates along a rotational axis of the tail when the drive cam is rotated by the tail in a first direction so as to removably insert the protrusion into the locking receptacle to restrict rotation of the handle with respect to the base.
A lockable actuator having a locked position and an unlocked position, the actuator comprising:
- a handle having a cavity;
- a lockset housed within the cavity, the lockset having a rotatable tail;
- a rotatable drive cam coupled to the rotatable tail and housed within the cavity;
- and
- a driven cam coupled to the drive cam and housed within the cavity, the driven cam having a protrusion;
- a base that receives a portion of the handle, the base having a locking receptacle;
- wherein the locked position is effectuated by rotating the tail in a first direction to move the driven cam along a rotational axis of the tail and insert the protrusion into the locking receptacle of the base, thereby restricting rotational movement of the handle with respect to the base;
- and
- wherein the unlocked position is effectuated by rotating the tail in a second direction that is opposite the first direction to move the driven cam along a rotational axis of the tail and remove the protrusion from the locking receptacle.
A latch actuating device comprising:
- a handle;
- a lockset housed within the handle, the lockset having a rotatable tail;
- a driven cam housed within the handle, the driven cam having a protrusion;
- a base that receives a portion of the handle such that the handle is rotatable with respect to the base, the base having a locking receptacle for receiving the protrusion;
- wherein the driven cam translates along a rotational axis of the tail when the tail is rotated so as to removably insert the protrusion into the locking receptacle to restrict rotation of the handle with respect to the base.
