Abstract
An electronic security keypad assembly includes a cover made of sheet metal, a keypad, and a mounting plate. Tabs extending the from the cover engage dented tab receiving regions of the mounting plate to secure the cover to the mounting plate. The tabs, when bent around the dented tab receiving regions, are obscured from access when mounted to a door, deterring physical tampering with the electronic keypad assembly.
Claims18
An electronic security keypad assembly comprising:
- a cover comprising a front surface portion having a plurality of openings, at least two side surface portions, and a plurality of fasteners extending therefrom;
- a keypad including a plurality of keypad buttons that are configured to be exposed through the plurality of openings in the cover, the plurality of keypad buttons being configured to convert physical input into electrical signals;
- and
- a mounting plate comprising a primary surface and a plurality of fastener receiving regions configured to receive the plurality of fasteners, wherein mating the fasteners to the fastener receiving regions comprises bending the fasteners into the fastener receiving regions such that when the fasteners are in a folded position within the fastener receiving regions, the fasteners are positioned in alignment with the primary surface and the keypad is secured between the cover and the mounting plate;
- wherein, when the electronic security keypad assembly is installed on a door, the primary surface resides approximately flush with a mounting surface of the door and the plurality of fasteners are positioned between the surface of the door and the mounting plate.
A method of assembling an electronic security keypad assembly, the method comprising:
- providing a cover formed from sheet metal, the cover having a front surface portion having a plurality of openings, at least two side surface portions, and a plurality of tabs extending from the at least two side surface portions;
- positioning a keypad between the cover and a mounting plate in alignment with the cover to allow a plurality of keypad buttons of the keypad to be exposed through the plurality of openings in the cover;
- and
- bending each of the plurality of tabs into tab receiving regions of the mounting plate until each of the plurality of tabs is positioned in alignment with a rearward surface of the mounting plate;
- wherein, when the electronic security keypad assembly is installed on a door, the rearward surface resides approximately flush with a mounting surface of the door and the plurality of tabs are positioned between the surface of the door and the mounting plate.
An electronic security keypad assembly mountable to a door, the electronic security keypad assembly comprising:
- a cover comprising a front surface portion having a plurality of openings, at least two side surface portions, and a plurality of tabs extending from the at least two side surface portions;
- a keypad including a plurality of keypad buttons that are configured to be exposed through the plurality of openings in the cover, the plurality of keypad buttons being configured to convert physical input into electrical signals, the keypad further including a printed circuit board assembly and a cable extending therefrom;
- and
- a mounting plate comprising a plurality of dented tab receiving regions that receive the plurality of tabs such that each of the plurality of tabs is bent into a position in alignment with a rearward surface of the mounting plate;
- wherein, when the electronic security keypad assembly is installed on a door, the tabs are positioned between a surface of the door and the mounting plate.
