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.
Claims59
A contact-minimizing door opening and closing system comprising:
- a handle;
- a control mechanism coupled to the handle at a first end and coupled to a latch bolt at a second end, the control mechanism being configured to control movement of the handle in response to a position of the latch bolt;
- and
- a push-push engaging and disengaging mechanism coupling the handle to a locking pin, actuation of the handle being configured to operate the engaging and disengaging mechanism to lock the door.
A contact minimizing door opening and closing system, comprising:
- a return mechanism having a first end configured to attach to a fixed surface and a second end mounted on a door, the return mechanism being configured to automatically place the door at a semi-open position when an external force on the door is absent;
- and a push-push engaging and disengaging mechanism coupling the handle to a locking pin such that movement of the handle is configured to operate the push-push engaging and disengaging mechanism to lock the door.
A contact-minimizing door opening and closing system comprising:
- a handle;
- a control mechanism coupled to the handle at a first end and coupled to a stopper component at a second end, the control mechanism being configured to control movement of the handle in response to a position of the stopper component;
- and
- a push-push engaging and disengaging mechanism coupling the handle to a locking pin, actuation of the handle being configured to operate the push-push engaging and disengaging mechanism to lock the door.
A method for locking and unlocking a door with minimal contact, comprising:
- providing a door lock having a striker, a locking pin and a push-push engaging and disengaging mechanism coupling a handle to the locking pin;
- providing a return mechanism having a first end. attached to a fixed surface and a second end coupled to the door;
- compressing the striker against a stake plate mounted to a door frame to unlock a movement of the handle;
- extending, by the push-gush engaging and disengaging mechanism, the locking pin into a hole formed on the strike plate in response to the striker being compressed against the strike plate;
- retracting, by the push-push engaging and disengaging mechanism, the locking pin from the hole in the strike plate in response to a force exerted on the handle such that the door is placed in an unlocked state;
- and
- activating the return mechanism to automatically place the unlocked door in a semi-open position.
A method for locking and unlocking a door with minimal contact, comprising:
- providing an opening mechanism configured to place the door to a semi open position;
- providing a door lock having a locking mechanism, a control mechanism, a handle and a push-push engaging and disengaging mechanism, the control mechanism configuring the handle to move the door to a closed position when a force is exerted at a first step, and the control mechanism configuring the handle to activate, by the push-push engaging and disengagini mechanism, the locking mechanism of the closed door at a second step;
- exerting, via the push-push engaging and disengaging mechanism, a force to the handle to place the door at an unlocked state;
- and
- activating the opening mechanism to automatically place the unlocked door to a semi-open position.
A contact-minimizing door opening and closing system comprising:
- a handle;
- a control mechanism coupled to the handle at a first end and coupled to a striker at a second end, the control mechanism being configured to control movement of the handle in response to a position of the striker;
- and
- a push-push engaging and disengaging mechanism coupling the handle to a locking pin, actuation of the handle being configured to operate the engaging and disengaging mechanism to lock the door.
