Filed:

Oct 2, 1989

Appl. No.:

7/416050

Inventors:

Roy T. Clay - Snyder NY
Donald J. Whiting - Akron NY

Assignee:

Whiting Roll-Up Door Mfg. Corp. - Akron NY

International Classification:

B60J 1000

US Classification:

277 12

Abstract:

A seal member (11) is adapted to seal the gap or space between a door panel (12) and frame (13) of a roll-up door assembly (10). The improved seal member includes a first portion (34) and a second portion (35). The first portion is mounted on the frame, and the second portion is biased to flexibly engage the outer surface of the door panel. The first portion is formed of a relatively-rigid vinyl, while the second portion is formed of a relatively-flexible vinyl, or may be in the form of a brush. The first portion has a raised abutment surface (42) arranged to engage the door panel, should the door panel move toward the frame, to prevent the second portion from becoming crushed between the first portion and the door. Thus, the second portion is protected from damage, and does not substantially impede vertical movement of the door. The first and second portions may be formed integrally or separately, as desired.

Abstract:

This invention provides two forms of improved guards for a roll-up door. The first form ( 58 or 59) is intended to prevent shifting cargo from intefering with becoming interlocked with the lowered door. This form has a vertically-elongated guard which is adapted to overlie the vertically-spaced hinges, and has opposite marginal end portions closely spaced to the knuckle portions of such hinges. This first form reduces the stepped configuration of prior art hinges, and therefore reduces the opportunity for shifting cargo to become interlocked with the door. The second form (111) is mounted on the door and track, and is designed to prevent shifting cargo from entering the space through which the door must pass as it its raised or lowered.
