Breakaway loading dock door system

摘要

A system for allowing a loading dock door to release from a track upon being struck by a fork lift or other sufficiently strong force. The system employs a unique track profile with one or more sidewalls that have an angled sidewall profile to allow a release assembly to move out of the track. The release assembly includes a biasing mechanism that allows the assembly to flex and ride out of the track when the door is impacted.

主权项

1. A dock door system comprising:
a first track and a second track, the first track comprising (i) a first sidewall comprising a first substantially planar region, (ii) a second sidewall comprising a second substantially planar region and (iii) a third sidewall comprising a third substantially planar region, the third sidewall being positioned between the first sidewall and the second sidewall, the first substantially planar region, the third substantially planar region and the second substantially planar region being consecutive planar regions, a first angle being defined by the first and third substantially planar regions and a second angle being defined by the second and third substantially planar regions, the first angle ranging from about 100° to about 160°; and a dock door comprising a first plurality of release assemblies and a second plurality of release assemblies, each of the first plurality of release assemblies comprising a puck and a biasing mechanism, each of the pucks biased by a respective one of the biasing mechanisms so as to ride in the first track, the first plurality of release assemblies being configured to allow the pucks to move toward the dock door and out of the first track if the door is struck with sufficient force in a direction that pushes the pucks against the first sidewall, wherein each of the pucks has a first major surface, a second major surface, a beveled edge extending from the first major surface to the second major surface and configured to be proximate to the first sidewall when the puck is positioned in the first track, and a second edge extending from the first major surface to the second major surface and configured to be proximate to the second sidewall when the puck is positioned in the first track.
