发明名称 Roller sealing apparatus for forming a weather seal between a vehicle and a loading dock or the like
摘要 A sealing apparatus for forming a weather seal between a vehicle and a loading dock is provided. In some embodiments, the apparatus includes a roller seal rotatably mounted to a support for rotation about an axis. The roller seal is movable in at least a vertical direction from a first position in the path of a vehicle entering the parking area, to a second position wherein the roller seal is disposed adjacent the top of the vehicle. Preferably, a curtain is suspended distally of the roller seal such that, when the roller seal is in the second position, the curtain forms a first seal with the top of the vehicle and the roller seal forms a second seal with the top of the vehicle. The curtain is semi-rigid and, in some instances, defines a ramping surface to facilitate movement of the roller seal over the leading edge of a vehicle approaching the loading dock.
