Abstract: A track assembly for an overhead door (10) includes a generally vertically positionable track segment (14) and a generally horizontally positionable track segment (15). The track segment (14) includes a curvilinear portion (17) at one end thereof which telescopically receives a curvilinear portion (21) of the track segment (15). The curvilinear portion (17) of the track segment (14) has a smaller radius of curvature than the curvilinear portion (21) of the track segment (15). In one embodiment, a bracket (30) has tabs (40) which are received in a slot aperture (42) in the curvilinear portion (17) to attach it to the bracket (30), and the bracket (30) has a lug (41) which is received in a slot (44) in the curvilinear portion (21) to attach it to the bracket (30). In another embodiment, the track segment (14) is carried by a bracket (51), and the track segment (15) is carried by a bracket (52) with the telescopic relationship being the only connection between the track segments (14, 15).

Abstract: A storm curtain assembly (10) includes a header (11) and side rails (13) extending downwardly from each end of the header (11). A roll (15) is positioned in the header (11) and carries a fabric curtain (14) which has one end attached to the roll (15). A bar (16) is attached to the other end of the fabric curtain (14). A track (20) is formed on each side rail (13), and the edges of the fabric curtain (14) are normally received in the tracks (20). One of the walls (18) which forms the track (20) terminates at an upper edge (21) which is spaced from the header (11) so that if an edge of the fabric curtain (14) is displaced from the track (20), the displaced edge will be allowed to be received in the track (20) as the fabric curtain (14) is being received on the roll (15).

Abstract: An assembly for covering a building opening that provides a shaft positioned at one end of the building opening, a curtain carried by the shaft, and a locking mechanism at the opposed end of the building opening from the shaft that selectively holds the curtain in a locked position to cover the building opening. The assembly also includes an input for selectively rotating the shaft, and a linking assembly adapted to transfer the input to the shaft to selectively rotate the shaft, wherein the linking assembly includes a failsafe portion designed to fail upon a predetermined impact force on the curtain. An operator is also provided to allow controllable movement of the curtain between the various positions.

Abstract: An overhead garage door (10) includes a plurality of panels (11) each carrying rollers (12) which ride in a track assembly (15). The track assembly (15) includes a generally vertically positionable component (16), a generally horizontally positionable component (17), and an arcuate transitional component (18) positioned between the vertical component (16) and the horizontal component (17). The vertical component (16) is generally U-shaped in end profile having a base portion (22) with branches (20, 21) extending from the edges thereof. The vertical component (16) is provided with a plurality of spaced separating systems (25), each of which includes a web (26) extending across the base portion (22) and the slots (28, 29) in the branches (20, 21). A selected portion of the length of the vertical component (16) may be removed by inserting a tool in the slots (28, 29) of one of the separating systems (25) and twisting it to break the webs (30, 31) adjacent to the slots (28, 29).

Abstract: A system for moving a barrier between limit positions, includes an operator motor assembly mounted proximate to the barrier, wherein at least a portion of the motor assembly is movable between an operating position and a locking position with the motor assembly blocking movement of the barrier. A bias assembly biases the motor assembly in the operating position and allows the motor assembly to move toward the locking position when either a predetermined force overcomes a biasing force or when the barrier is moved to a closed limit position or when forced entry is imposed on the barrier. The biasing force may be adjusted by moving posts on the motor assembly that are engaged by the bias assembly. A disengagement feature may also be provided that allows pivotable movement of the motor assembly even when in a locking position. And the pivoting motor assembly may be used as a secondary entrapment input to an operator controller.

Abstract: A track assembly for an overhead door (10) includes a generally vertically positionable track segment (14) and a generally horizontally positionable track segment (15). The track segment (14) includes a curvilinear portion (17) at one end thereof which is joined to a curvilinear portion (21) of the track segment (15) by a bracket (30). The curvilinear portion (17) of the track segment (14) has a smaller radius of curvature than the curvilinear portion (21) of the track segment (15). The bracket (30) has tabs (40) which are received in a slot aperture (42) in the curvilinear portion (17) to attach it to the bracket (30), and the bracket (30) has a lug (41) which is received in a slot (44) in the curvilinear portion (21) to attach it to the bracket (30).

Abstract: An overhead door system including, a sectional door (D") having top, bottom, and intermediate panels (321, 324, 322) hinged for moving between a closed vertical position and an open horizontal position, top rollers (332) on the top panel, bottom rollers (341) on the bottom panel, intermediate rollers (337) positioned between the top rollers and the bottom rollers, inner vertical tracks (351) for engaging the intermediate rollers, transition tracks (353) connected to the inner vertical tracks and curving through an angle of approximately ninety degrees for directing the travel of the intermediate rollers, horizontal tracks (355) extending from the transition tracks for engaging the intermediate rollers to support the door in the open horizontal position, and outer vertical tracks (357) for guiding the bottom rollers in a substantially vertical path paralleling said inner vertical tracks and having upper extremities (357') that are inwardly offset in the direction of the transition tracks.
