摘要:
A jamb bracket (10, 40) and track (30, 60) assembly for the support of overhead sectional doors and the like. The assembly comprises bracket means (10, 40) having tab means (20, 50) and track means (30, 60) having tab slots (34, 74). The tab means (20, 40) engage the tab slots (34, 74) for attachment of the bracket means (10, 40) to the track means (30, 60). A related jamb bracket (10, 40) comprises a U-shaped main body (14, 44), providing first and second perpendicularly disposed legs (16, 46 and 18, 48) and, tab means (30, 60) offset from the main body (14, 44).

The system includes a plurality, preferably a pair of parallel tracks (22) disposable on opposite sides of a window or skylight or on window mullions (24), a plurality of shade carriers (44) secured to and riding in the tracks and a flexible, foldable, resilient sun shade (60) secured along its length to spaced ones of the carriers for movement with the carriers along the tracks. A shade mover such as a hand cord brake assembly (124) or a motorized roller (64) and cord assembly is also provided for urging the shade to a desired location relative to the tracks. Each track may be rectangular in cross-section, and curved or straight along its length, receives the shanks (46) and rollers (50, 52) or slides of the carriers and includes an end stop (40). Each carrier can include a hook (48) insertable through openings (62) in the shade. A partition can be provided in the track to restrict oscillation of the rollers or slides and shank therein. The system is well adapted for use with a variety of straight, curved and angled windows.

A hinge assembly (20) pivotally couples adjacent panels (14) together in an overhead sectional door (10). The panels (14) include stiles (38) between each lateral end of the panel (14) to which the hinge assemblies are attached. The hinge assembly (20) Includes an upper hinge leaf (70) on an upper panel with a pair of spaced generally parallel flanges (90) which span the juncture between the upper and lower panels. The hinge assembly (20) also Includes a lower hinge leaf (72) with a pair of flanges (90) projecting generally parallel to each other. The lower hinge leaf is mounted to one of the stiles (38) of the lower panel and each flange includes a pivot axis hole near a terminal end thereof for alignment with a pivot axis hole In one of the flanges (90) of the upper leaf (70).
摘要:
An overhead door apparatus (10) utilizing a torsion spring counterbalancing mechanism (30). The counterbalancing mechanism (30) includes a worm drive ring-shaped gear winding mechanism (38) for setting the appropriate torque or number of winds in the spring (32). A counting mechanism (140) is provided to indicate to the installer the number of winds being given to the spring (32). Means are also provided for accommodating spring growth and contraction during winding and unwinding using the winding mechanism (38) and during normal raising and lowering of the door (12). A spring clip gear retainer (82) is disclosed for preventing rotation or creep of the worm drive gear (70) and spur gear (56) during normal raising and lowering of the door (12). A second embodiment is disclosed allowing more universal interchangeability of components between the left and right sides of the door system (200), easy snap-in assembly, and including a telescoping spring cover (252). Each embodiment includes a spring winding counter (140).
