Abstract
A privacy keypad providing privacy for keypad character entry and concealment of a joint in an escutcheon. A privacy keypad may include a faceplate, a keypad disposed on the faceplate, and at least one protrusion integral with the faceplate. An escutcheon for a door lock may include a housing, a keypad disposed on the housing for unlocking the door lock, and at least one protrusion integral with the housing. The protrusion may obstruct at least partially a line of sight to the keypad. An escutcheon may include top and bottom covers with the top cover projecting outward from the surface of a door more than the lower cover, resulting in an at least partially hidden joint between covers. Top and bottom covers may be interchangeable with covers having similar edges.
Claims20
A privacy keypad comprising:
- a faceplate;
- a keypad disposed on the faceplate and having a central longitudinal axis and a center point;
- and
- at least one protrusion integral with the faceplate and extending upwardly from the surface of the faceplate laterally adjacent to the keypad,
- wherein the at least one protrusion is of a sufficient height and length along the central longitudinal axis of the keypad to obstruct at least partially a line of sight to the keypad, and
- wherein a line from the center point of the keypad normal to the central longitudinal axis of the keypad to the top of the at least one protrusion forms an angle of at least 20 degrees with a plane tangential to the surface of the faceplate along the central longitudinal axis of the keypad.
An A privacy keypad, comprising:
- a faceplate;
- a keypad disposed on the faceplate and having a central longitudinal axis;
- and
- two protrusions, extending upwardly from the surface of the faceplate laterally adjacent to and on opposite sides of the keypad to define a longitudinal channel in the faceplate for receiving the keypad,
- wherein the protrusions are integral and of unitary construction with the faceplate, and each protrusion is of a sufficient height and length along the central longitudinal axis of the keypad to obstruct at least partially a line of sight to the keypad, and
- wherein a line from the center point of the keypad normal to the central longitudinal axis of the keypad to the top of at least one protrusion forms an angle of at least 20 degrees with a plane tangential to the surface of the faceplate along the central longitudinal axis of the keypad.
A privacy keypad comprising:
- a faceplate;
- a keypad disposed on the faceplate and having a central longitudinal axis;
- and
- exactly two protrusions extending upwardly from the surface of the faceplate laterally adjacent to and on opposite sides of the keypad,
- wherein the two protrusions are of sufficient height and length along the central longitudinal axis of the keypad to obstruct at least partially a line of sight to the keypad.
A privacy keypad comprising:
- a faceplate;
- a keypad disposed on the faceplate and having a central longitudinal axis;
- and
- a plurality of protrusions extending upwardly from the surface of the faceplate laterally adjacent to and on opposite sides of the keypad,
- wherein the plurality of protrusions defines a channel having open ends, and
- wherein the plurality of protrusions is of sufficient height and length along the central longitudinal axis of the keypad to obstruct at least partially a line of sight to the keypad.
A privacy keypad comprising:
- a faceplate;
- a keypad disposed on the faceplate and having a central longitudinal axis;
- and
- at least one protrusion integral with the faceplate and extending upwardly from the surface of the faceplate laterally adjacent to the keypad,
- wherein the at least one protrusion is of a sufficient height and length along the central longitudinal axis of the keypad to obstruct at least partially a line of sight to the keypad, and
- wherein the at least one protrusion comprises a light source.
