Abstract
A locking system enabling selective handle turning direction to operate an unlocking mechanism is provided. The system comprises a handle, a gear rack driven linearly by rotation of the handle, and a plate removably coupled to the gear rack by a coupling means, wherein the plate moves in a first linear direction in response to handle rotation. When the coupling means is in a first position to couple the plate to the gear rack, a clockwise rotation of the handle displaces the plate in the first linear direction. When the coupling means is in a second position to couple the plate to the gear rack, a counter-clockwise rotation of the handle displaces the plate in the first linear direction. Movement of the plate in the first direction operates the unlocking mechanism.
Claims9
A locking system enabling selective handle turning direction to operate an unlocking mechanism, comprising:
- a) a handle,
- b) a gear, rotationally fixed to said handle,
- c) a first gear rack driven linearly a first direction by rotation of said handle,
- d) a second gear rack driven linearly in a second direction by rotation of said handle,
- e) a selector, and
- f) a driving plate with a first opening and a second opening selectively coupled to said first gear rack by said selector, wherein said selector is inserted through the first opening to selectively couple said first gear rack to said driving plate in one of a first selected position and a second selected position, wherein said driving plate moves in a first linear direction in response to handle rotation, wherein when said selector is in said first selected position to couple said driving plate to said gear rack, a rotation of said handle in a first rotational direction displaces said driving plate in said first linear direction, wherein when said selector is inserted through the second opening of the driving plate in said second selected position to couple said driving plate to said second gear rack, a rotation of said handle in a second rotational direction displaces said driving plate in said first linear direction, wherein movement of said driving plate in said first linear direction operates said unlocking mechanism, and wherein said first rotational direction is opposite of said second rotational direction.
