Abstract
An electronic door lock system includes a gasket system for protecting electrical and mechanical components from exterior water and air. A lock portion may include a gasket, a circuit board, and a plate disposed between a first and second housing. The gasket includes an L-shaped perimeter that wraps around a first side and perimeter edge of the circuit board. The plate compresses the gasket perimeter against a ridge on the first housing to form a seal around the circuit board.
Claims8
A door lock system comprising:
- an exterior lock portion including an exterior escutcheon and an exterior housing;
- a printed circuit board disposed between the exterior escutcheon and the exterior housing;
- a gasket disposed on a first side of the printed circuit board, wherein the gasket includes an L-shaped perimeter that wraps around a perimeter of the circuit board and covers a portion of a second side of the printed circuit board;
- and
- a plate disposed between the gasket and the exterior escutcheon, wherein the plate is configured to compress the L-shaped perimeter of the gasket against a ridge that protrudes from the exterior housing, wherein the ridge is configured to compress into the L-shaped perimeter to create a seal around the printed circuit board.
A door lock system comprising:
- an exterior lock portion;
- an outer spindle disposed in the exterior lock portion that extends through an opening in the exterior lock portion;
- and
- a gasket disposed in the exterior lock portion, wherein the gasket includes an opening through which the outer spindle extends, the opening including a beveled perimeter having a smaller diameter on an outer surface than a diameter on an inner surface, wherein the smaller diameter of the opening is smaller than a diameter of the outer spindle such that the smaller diameter is configured to compress against the outer spindle.
A door lock system comprising:
- an interior housing having a battery compartment disposed therein, the interior housing including a slanted surface at least partially surrounding the battery compartment, wherein the slanted surface includes a rib that protrudes from the slanted surface around at least a portion of the battery compartment;
- a battery cover enclosing the battery compartment, and wherein an inner surface of the battery cover includes a slanted surface that complements the slanted surface on the housing;
- and
- a first compressible insert disposed between the slanted surface of the housing and the slanted surface of the battery cover, wherein the rib on the slanted surface is configured to compress into the first compressible insert.
