  • Patent number: 7984631
    Abstract: A modular escutcheon for a door lock including a plurality of covers. Each higher cover may progressively project outward from the surface of a door more than the covers below. Top and bottom edges of adjacent covers abut to form a joint, which may be partly or completely concealed resulting from the outward projections of higher covers. An escutcheon system may be provided that includes interchangeable parts, for example, there may be several different intermediate covers for use with the same lower and upper covers, or different upper covers that may be used in the same position. A variety of lock operating devices may be provided with the different covers to achieve different systems.

  • Patent number: 7334442
    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.
