Abstract
An electronic door lock includes a housing having a keypad window, a keypad inserted into the keypad window and having a plurality of depressible buttons, and a bezel surrounding the keypad and having a spar, the spar lying between the buttons and providing support to the plurality of depressible buttons in a direction substantially perpendicular to a press direction. The electronic door lock may also have a circuit board which detects button depressions. The housing may be constructed with a single cut designed to enclose multiple buttons, reducing manufacturing costs. The keypad may have a flexible support webbing with chambers corresponding to the buttons. Certain chambers may be connected, allowing a single LED to illuminate multiple buttons, further reducing manufacturing cost.
Claims26
An electronic door lock comprising:
- a housing having a keypad window;
- a keypad inserted into the keypad window and having a plurality of depressible buttons;
- and
- a bezel surrounding the keypad and having a spar, the spar lying between the buttons and providing support to the plurality of depressible buttons in a direction substantially perpendicular to a press direction.
A method of manufacturing an electronic door lock comprising:
- forming a keypad window in a lock housing;
- inserting a bezel into the keypad window, the bezel comprising a plurality of spars;
- aligning a plurality of buttons of a keypad with respective spaces between the plurality of spars;
- inserting the keypad into the keypad window;
- aligning webbing recesses of the keypad with respective LEDs disposed on a circuit board;
- and
- securing the bezel, the keypad, and the circuit board to the lock housing.
An electronic door lock comprising:
- a lock body having a keypad window and substantially defining an interior volume;
- an elastomeric keypad disposed in the keypad window, the elastomeric keypad comprising:
- a plurality of buttons;
- an integrated webbing configured to provide a longitudinal reaction force to return a particular button of the plurality of buttons to a non-depressed orientation in response to the particular button being pressed;
- and
- a sealing flange substantially lying in a plane perpendicular to the longitudinal reaction force;
- and
- a circuit board disposed in the interior volume and comprising an LED;
- wherein the elastomeric keypad contacts the circuit board;
- and
- the sealing flange is positioned to prevent water from entering a volume between the elastomeric keypad and a circuit board behind the elastomeric keypad.
