Abstract
A touch screen electronic deadbolt includes a planar, exterior touch panel with a touch overlay for receiving tactile input for entry of an access code to engage and disengage a deadbolt. The touch panel is contained within a housing cavity of a rectilinear housing. A touch overlay rests above the housing cavity extending to the edge of the housing without the use of a bezel or frame, thus providing a sleek and low profile appearance. An interior escutcheon may be in communication with the exterior touch panel allowing a user to manually engage and disengage the deadbolt from within a dwelling.
Claims18
An electronic deadbolt comprising:
- an exterior touch panel configured for exterior, all-weather use comprising:
- a touch overlay configured to receive tactile input into the touch panel from a user, wherein the touch overlay comprises an electroluminescent material configured to both illuminate the touch panel and also detect the tactile input;
- a top printed circuit board secured to the touch overlay;
- a diffuser biased towards the top printed circuit board opposite the touch overlay;
- a spacer biased towards the diffuser opposite the top printed circuit board;
- a bottom printed circuit board adjacent the spacer and diffuser;
- and
- a PCB housing forming a PCB housing cavity configured to receive the touch overlay such that the top printed circuit board, the diffuser, the spacer, and the bottom printed circuit board are received within the PCB housing cavity, wherein the touch overlay rests above the PCB housing cavity;
- and
- a second housing with sides forming a second housing cavity configured to receive the PCB housing such that the PCB housing nests within the second housing cavity and the touch overlay rests above the second housing cavity;
- wherein an opening in a rear surface of the exterior touch panel is sealed, therefore preventing moisture from entering the second housing.

A touch screen electronic deadbolt comprising:
- an exterior touch panel configured for all-weather use comprising:
- a touch overlay configured to receive tactile input into the touch panel for engaging and disengaging the touch screen electronic deadbolt, wherein the touch overlay comprises an electroluminescent material configured to both illuminate the exterior touch panel and also detect the tactile input;
- a printed circuit board adjacent the touch overlay;
- a diffuser secured to the printed circuit board opposite the touch overlay;
- a spacer adjacent the diffuser opposite the printed circuit board;
- a bottom printed circuit board adjacent the spacer opposite the diffuser;
- and
- a housing with four sides forming a housing cavity configured to receive the exterior touch panel such that the printed circuit board, the diffuser, the spacer, and the bottom printed circuit board are received within the housing cavity, wherein the touch overlay rests above the housing cavity;
- wherein an opening in a rear surface of the exterior touch panel is sealed, therefore preventing moisture from entering the housing;
- wherein a conformal resin secures the printed circuit board, the diffuser, the spacer, and the bottom printed circuit board within the housing cavity;
- and
- an interior escutcheon in communication with the exterior touch panel comprising:
- an interior turn piece extending from the interior escutcheon configured to engage and disengage the touch screen electronic deadbolt.

A keyless electronic deadbolt controller comprising:
- an exterior touch panel configured for exterior, all-weather use comprising:
- a deadbolt configured to lock and unlock for securing an entry door;
- a touch overlay configured to receive tactile input into the exterior touch panel for locking and unlocking the deadbolt, wherein the touch overlay comprises an electroluminescent material configured to both illuminate the touch panel and also detect the tactile input;
- a flexible printed circuit board mounted proximate the touch overlay;
- a diffuser proximate the flexible printed circuit board opposite the touch overlay;
- a spacer adjacent the diffuser and opposite the flexible printed circuit board;
- a bottom printed circuit board adjacent the spacer opposite the diffuser;
- and
- a housing with sides forming a housing cavity configured to receive the touch panel such that the flexible printed circuit board, the diffuser, the spacer, and the bottom printed circuit board are received within the housing cavity with the touch overlay resting above the housing cavity;
- wherein an opening in a rear surface of the exterior touch panel is sealed, therefore preventing moisture from entering the housing;
- and
- wherein an adhesive secures the touch overlay to a perimeter of the housing along the sides thus securing the flexible printed circuit board, the diffuser, the spacer, and the bottom printed circuit board within the housing cavity;
- and
- an interior escutcheon in communication with the exterior touch panel comprising:
- an interior turn piece extending from the interior escutcheon configured to lock and unlock the deadbolt when manually manipulated.
