Abstract
Abstract An inflatable dock seal for closing the area around a dock opening in a wall with respect to a truck or a trailer has an upper horizontal section and a pair of vertical sections in communication therewith. Elongated uninflated flexible tubular members on each of the vertical sections are slidably engaged over structural members secured to the wall and spaced flexible longitudinal flanges on the upper horizontal section are clampingly secured between distortable clamping members on a mounting strip on the wall.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 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 inflatable member arranged in an inverted U-shape and having an upper horizontal section and a pair of spaced vertical sections, flexible noninflatable longitudinally positioned channel-like fastening members on the exterior of at least two of said sections, said fastening members each being integral and U-shaped with the open side facing toward a corresponding vertical section and having attached flanges on each leg thereof, said flanges being attached to said corresponding vertical section to close said fastening member, said fastening members each having an open end, rigid elongated structural members each slidably received therein through said open end to be positioned one in each of said channel-like fastening members, said structural members being attached to said wall through said fastening members beside said dock opening to hold said sections of said inflatable member thereagainst via said fastening members, and means for inflating said inflatable member.
