A door coupling (10) for coupling a garage door (102) to a guide track assembly. The door coupling has a shaft member (12) with a body (24) mounted thereon. The shaft includes a spring (26) located inside the body. The other end of the spring is positioned to abut with the inside of a cap (22) that mates with a thread 30 on the first end of the body. The body is pre-tensioned to move along the shaft towards the guide track assembly and having a first end facing the guide track assembly and a second end opposed to the first end. The body includes an attachment point for an eye bolt (32) that also includes a part that passes through an aperture in a threaded cap (34) on the body. The door coupling addresses the problem of high winds causing deflection of garage doors which can cause them to becoming loose and even detaching from their mounting frames. In use, and upon deflection of the door, the body is adapted to move towards the guide track assembly and apply a force that at least partially corrects said deflection, thus mitigating the known problem.

BRACING MEMBER, COUPLING AND SYSTEM FOR A SECTIONAL DOOR
A bracing member for a door guide track (28A), the door guide track being adapted to receive a roller member (38) for a garage door roller assembly (30A), which includes a shaft (40) around which panels (27A) of a garage door are wound. The bracing member comprises a body in the form of a sleeve (10A) that defines an interior space into which a section of the door guide track is retained. The bracing member has a longitudinal opening (22) so that does not interfere with normal operation of the roller assembly. The sleeve has return sections that engage an abutment member (42) of the roller assembly and stop the bracing member from spreading when under load, for example under windy conditions. The bracing member can be affixed to a solid structure such as a garage wall and includes strengthening ribs on its exterior.

Abstract
A panel for a sectional door, the panel comprising: (a) a front wall; (b) a rear wall; (c) a top edge; (d) a bottom edge; (e) two side edges; (f) a first mounting means for mounting the panel in a pair of first guide tracks, one of each said pair of first guide tracks located adjacent each of said side edges; (g) a first rigid reinforcement member extending between said top and bottom edges to reinforce said panel against deflection; and (h) a first non-rigid restraining member located between said side edges to restrict the deflection of the panel, wherein said first non-rigid restraining member defines a path that runs adjacent to or through said first rigid reinforcement member and comprises a second mounting means for anchoring said first non- rigid reinforcement member to an anchor point.

A track rail (46) forming part of a track assembly (14) for a sectional door (13) for movement between closed and open conditions. The track rail (46) comprises an elongate body (80) having a longitudinal web (81) and two opposed longitudinal sides (82, 83) which cooperate to define a channel interior (84). The longitudinal web (81) is configured to define a longitudinal space (92) adjacent to and opening onto the channel interior (84).
A track radius structure (70) adapted to be mounted on a wall to form part of the support structure for a sectional door (13). Track radius structure (70) comprises a body (101) having a bottom end section (113) adapted for connection to a first track rail and an outer end section (111) adapted for connection to a second track rail, and a curved transition track section (45) extending between the bottom end section and the outer end section to cooperate with the first and second track rails to provide a continuous track for a roller.

A roller assembly (35) for movement along a body (80) defining a track for a sectional door (13) movable between open and closed conditions. The roller assembly (35) comprises a support roller (155) and a keeper (157), the support roller (155) being adapted for guided rolling movement along the track, and the keeper (157) being adapted to constrain the support roller for rolling movement along the track. The keeper (157) comprises a keeper sleeve (173), a keeper plate (175) and a keeper abutment (176) configured as a skid. The keeper sleeve (173), the keeper plate (175) and the keeper abutment (176) are of integral construction and are defined by a body (177) formed of a plastics material.
