Snubber devices for use in roll-up door assemblies
An improved roll-up door assembly (10) is configured to be coupled to a storage container, such as a truck trailer (11), and broadly comprises: a roll-up door including a plurality of door panels (12A-12G), of which adjacent panels are hingedly coupled to one another; a hinge (29) having an first hinge plate (30) coupled directly to a bottom panel (12A) of the door, having a second hinge plate (31), and having a hinge joint (32) pivotally coupling the first and second hinge plates to one another for enabling relative movement therebetween; a bottom roller (33) coupled to the second hinge plate for movement therewith about the joint; a counterbalance mechanism mounted on the storage container; a cable (22) connecting the counterbalance mechanism to the bottom door panel; and a snubber (26) surrounding the cable and adapted to engage the counterbalance mechanism when the bottom door panel is moved toward the counterbalance mechanism.
