A dock shelter for effecting a seal between the rear end of a truck van and a building to keep out wind and rain comprises a frame having sides and a roof for enclosing the building opening. Flexible, but substantially self-sustaining, foam-filled sealing panels extend toward each other from the left and right inside of a substantially rigid frame to define an opening which is somewhat smaller than the expected width of the van. A partially foam-filled curtain also extends from the top of the frame and behind the left and right side panels. The top curtain has vertically extending stays which augment effecting a seal with the top of the van. The top curtain and the side panels cooperate to maintain the seal when the top corners of the van approach the building opening. The lower ends of the side panels are deflected into sealing relationship with specially shaped flexible foam filler blocks which are located inside of and near the bottom of the frame. The side panels have quilted reinforcements in areas that are subject to substantial abrasion.
A loading dock shelter comprising:
The dock shelter as in claim 5 wherein said flexible pad means are comprised of a block of flexible foam material and a covering of flexible sheet material encasing said foam material.
In a dock shelter having a substantially rigid frame including side frame sections for projecting outwardly from a building wall at the sides of a doorway and yieldable sealing panels extending from said frame sections toward each other in spaced relation to said wall whereby to yield and seal against a vehicle body interposed therebetween, the improvement in which said yieldable panels comprise substantially self-supporting vertically elongated pads, and resilient hinged connections between outboard edges of said pads and the said side frame sections whereby said pads are swingable as panel units about said hinged connections under pressure of an entering vehicle body and seal against said body under the pressure of said resilient hinged connections.
