Stab-resistant seals for loading platforms

Abstract

A stab resistant seal for a loading dock is disclosed. An example weather barrier device disclosed herein includes a canopy having a rear end and a front end, wherein when the canopy is mounted to the wall, the rear end is mountable to the wall over the doorway, and the front end projects forwardly from the wall. A front bar is at the front end of the canopy, and the front bar is horizontally elongated. The rear curtain hangs from the front rod. The rear curtain has an upper curtain edge attached to the front bar. The rear curtain has a lower edge that is at a lower height than the upper edge of the doorway when the canopy is mounted to the wall. The rear curtain has a curtain width. The front panel hangs in front of this rear curtain. The front panel is less flexible than the rear curtain. The front panel has a panel width of approximately 50% to 80% of the shade width. A space is between and defined by the front panel and the rear curtain.

Description

technical field [0001] The present disclosure relates generally to weather barrier devices, such as dock seals and / or dock shields, for vehicle loading docks, and more particularly to stab resistant seals for loading docks. Background technique [0002] Platform weather barriers (weather barrier devices), such as platform seals and platform shields, limit or prevent outdoor environmental conditions or pollutants (e.g., rain, snow, wind, high / low temperatures, insects, animals, etc.) during vehicle loading or unloading Get inside buildings and vehicle cargo areas. The platform guards and seals also prevent conditioned air within the building and / or vehicle cargo area from flowing into the outdoor environment. Examples of station seals and / or shields having various roof configurations and side configurations are disclosed in US Patent Nos. 6,205,721; 6,233,885; 7,185,463 and 8,307,588. [0003] Some known platform seals use side members having a compressible foam core or bod...

AI Technical Summary

Problems solved by technology

However, when the platform seal side members are compressed, they can displace into or encroach into the opening in the rear of a parked vehicle

Therefore, the compressed side members may interfere with the forklift and / or operator during loading and unloading operations

In addition, inflatable platform seals are susceptible to energy loss and tearing which compromises the ability of the side members to inflate to provide an acceptable seal
