Abstract
Abstract A mounting for an inflatable dock seal which is used for closing the area around a dock opening in a wall with respect to a truck or trailer provides uninflated flexible tubular members on several sections of the inflatable dock seal and positions structural members in the flexible tubular members. A rigid mounting channel is secured to the wall about the dock opening which permits the quick and easy engagement of the structural members within the channel. Cylindrical holding plugs are then positioned in the channel locking the inflatable dock seal on the wall about the dock opening therein.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
136 words
An inflatable dock seal and mounting therefor for positioning said dock seal on a wall above and beside a dock opening therein and comprising at least one flexible inflatable member arranged in an inverted U-shape having an upper horizontal section and a pair of spaced vertical sections, flexible channel members formed on the exteriors of said horizontal and vertical sections, elongated structural members of known widths positioned in said flexible channel members, rigid cross sectionally C-shaped channel members having opposed edges with the width of the opening between said opposed edges being less than the known width of said elongated structural members, said elongated structural members and said flexible channel members being movably engaged in said rigid cross sectionally C-shaped channel members, the arrangement requiring said elongated structural members to be moved edgewise when positioned therein.
