Abstract: A double rotary lock includes a housing defining an interior space, and lock and latch members rotatably mounted in the interior space. A link member is coupled to the lock member and is rotatable with the lock member. An electronic linear actuator is mounted in the interior space of the housing and is coupled to the link member and rotates the link member and the lock member between lock and unlock positions. A sliding door assembly, and method of locking a sliding door are also provided.

Abstract: An inventive hinge has the ability to be biased toward open and closed positions and/or is adapted to be hidden in door assemblies. The hinge includes a first bracket adapted to be mounted to a first workpiece. The first bracket comprises a generally tubular sleeve and opposed spaced-apart surfaces including first openings that are aligned with each other. A second bracket is adapted to be mounted to a second workpiece. The second bracket comprises opposed spaced-apart surfaces including second openings that are aligned with each other. The first bracket and the second bracket are oriented with respect to each other effective to align the first openings with the second openings. A hinge pin is received in the first and second openings effective to enable the first bracket to be pivotally movable relative to the second bracket. The tubular sleeve extends from the first bracket generally parallel with an axis of the hinge pin.
