发明名称 Loading dock shelters
摘要 A loading dock shelter for use around a doorway on wall, includes a flexible head cover panel, having top, bottom and side edges. Two sleeves, each sleeve secured to opposite side edges of the head panel to an intermediate area between the top and bottom edges, slidably receive two flexible elastic straps respectively. One end of each strap extends upward toward the top edge of the head panel and one end of each strap extends in a taut draped manner from the sleeve. The ends of the strap are secured in a stationary manner to the side frame member. The flexible elastic straps restrain and cushion the head panel as the head panel is subjected to outside forces reducing strain and wear, yet allowing the head curtain to yield upon engagement with a truck.
