  • Patent number: 6948285
    Abstract: In order to provide a durable loading dock shelter with an effective seal, the dock shelter is provided with a face panel that is relatively lightweight and firm, yet moveable for sealing against vehicles of various size and position. The face panel can be used as a side curtain or a head curtain. To provide the face panel with durability while minimizing its weight, the face panel is thermoformed of twin sheets of plastic to provide a durable outer shell with a hollow interior. In some embodiments, the face panel is moveable by virtue of an integral living hinge that connects the face panel to a generally stationary support panel.
