Abstract
A contact-minimizing door opening and closing system for a door has a handle including a shaft with an endplate disposed on the shaft opposite the handle and a latch bolt including a pin positioned to contact the endplate. The pin prevents movement of the handle when the latch bolt is extended from a lock housing, and allows movement of the handle when the latch bolt is retracted into the lock housing. An engaging and disengaging mechanism couples the handle to a locking pin such that movement of the handle is configured to operate the engaging and disengaging mechanism to lock the door.
Claims20
A contact-minimizing door opening and closing system comprising:
- a handle;
- a handle stabilization mechanism coupled to the handle at a first end and coupled to a latch bolt at a second end, the stabilization mechanism configured to control movement of the handle in response to a position of the latch bolt;
- and
- an engaging and disengaging mechanism coupling the handle to a locking pin, actuation of the handle configured to operate the engaging and disengaging mechanism to lock the door.
A contact-minimizing door opening and closing system comprising:
- a handle including a shaft with an endplate disposed on the shaft opposite the handle;
- a latch bolt including a pin positioned to contact the endplate, the pin preventing movement of the handle when the latch bolt is extended from a lock housing, and allowing movement of the handle when the latch bolt is retracted into the lock housing;
- and
- an engaging and disengaging mechanism coupling the handle to a locking pin, movement of the handle configured to operate the engaging and disengaging mechanism to lock the door.
A method for locking and unlocking a door with minimal contact, comprising:
- mounting a handle to a door, the handle coupled to an engaging and disengaging mechanism;
- unlocking movement of the handle by compressing a latch bolt;
- extending a locking pin coupled to the engaging and disengaging mechanism into a receptacle formed on the strike plate in response to the latch bolt being compressed against the strike plate;
- and
- retracting the locking pin from the receptacle in response to a translational force exerted on the handle by an individual.
