SNUBBER DEVICES FOR USE IN ROLL-UP DOOR ASSEMBLIES

摘要

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.

1. A roll-up door assembly mounted on a storage container, such as a truck trailer, comprising:
a roll-up door including a plurality of door panels, of which adjacent panels are hingedly coupled to one another; a hinge having an first hinge plate coupled directly to a bottom panel of said door, having a second hinge plate, and having a hinge joint pivotally coupling said first and second hinge plates to one another for enabling relative movement therebetween; a bottom roller coupled to said second hinge plate for movement therewith about said joint; wherein said door is adapted to be moved between a closed position at which said bottom door panel is in a vertical orientation, and an opened position at which said bottom door panel is in a horizontal orientation; a counterbalance mechanism mounted on said storage container; a cable connecting said counterbalance mechanism to said bottom door panel; and a snubber surrounding said cable and adapted to engage said counterbalance mechanism when said bottom door panel is selectively moved toward said counterbalance mechanism.
