International Classification:

E05F 15/643

Abstract:

A door system includes a multi-panel door and a dual-synchronization drive assembly for the door system. The dual-synchronization drive assembly has a structural configuration and functionality that combines a drive mechanism with a synchronization mechanism. The dual-synchronization drive assembly transmits a drive force in a manner that causes linear movement of door panels of the multi-panel door system between an open position and a closed position. The dual-synchronization drive assembly causes a synchronized movement of the door panels at different linear speeds/velocities to fully advance the door panels to the open position or the closed position simultaneously. The dual-synchronization drive assembly includes a dual gear unit that is configurable to allow for any motion/speed ratio necessary in order to obtain a specific performance objective of the door system.

Abstract:

A door system includes a header having a guide rail that has a central portion having a notch. A panel hanger is slidably coupled to the header. A door panel has a handle end portion releasably coupled to the panel hanger and a pivot end portion pivotably coupled to the panel hanger. The panel hanger and the door panel slide in unison between a closed position and a fully open position along a longitudinal plane. An interlock plate is positioned to extend upwardly from the door panel, and has a downwardly extending guide slot that slidably receives the guide rail of the header. When the door panel is in the fully open position, the interlock plate is aligned with the notch of the guide rail of the header in a direction orthogonal to the longitudinal plane to facilitate a pivoting of the door panel away from the longitudinal plane.

International Classification:

E05B 7/00
E05B 15/02

Abstract:

A slide latching system for latching a sliding door panel to a door frame includes a jamb strike, a latch assembly, and a handle set. The jamb strike is connected to the door frame. The latch assembly is connected to the sliding door panel, and has a latch member having a latch hook portion configured to engage the jamb strike. The latch hook portion is movable between a latched position and an unlatched position. The handle set is mounted to the sliding door panel. The handle set is drivably coupled to the latch assembly. The handle set is configured to facilitate both of a moving of the latch hook portion of the latch assembly to the unlatched position and a sliding of the sliding door panel in a first direction in a continuous motion applied to the handle set by a user.

Abstract:

A retractable latch hook shroud assembly includes a base plate, a first post, a second post, a shroud, and a spring biasing mechanism. The first post extends from the base plate in a first direction. The second post extends from the base plate in the first direction, and the second post is spaced away from the first post in a direction orthogonal to the first direction. A shroud has an end wall and a side wall that extends away from the end wall. The side wall defines a latch hook recess. The end wall has a first hole and a second hole. The first hole is configured to slidably receive the first post and the second hole is configured to slidably receive the second post. The spring biasing mechanism is interposed between the base plate and the end wall of the shroud.
