Abstract: An improvement in a dock seal of the type in which a movable panel in its disengaged position extends generally from the side of the dock opening toward the center of the dock opening and when engaged by the exterior of a truck is moved backwardly by the truck. The improvement is a lip panel which is attached to and runs along the inner edge of the movable panel and when not engaged by the truck extends generally away from the dock opening. The lip panel seats against a truck when the dock seal is engaged by a backing truck and moved toward the dock opening with the truck into sealing engagement of the gap between an open truck door and the truck body.

Abstract: A cover for refrigerated display cases formed from a plurality of flexible, transparent, PVC strips attached together in side by side relation to form panels which extend across the display case access opening to provide a barrier which substantially reduces the heat transfer between the store environment and the display case contents.

Abstract: A bumper seal to be disposed on the exterior of a building at the lower edge of a doorway and against which a truck or trailer can back to seal its deck edge against the building. It comprises a resiliently yieldable and compressible sealing body member extending transversely below the opening between two bumper blocks disposed at opposite sides of the opening. The seal is removably mounted so it can be replaced when worn. In addition, it is so mounted that a dock plate can be positioned thereover and will interfit with its mounting means to prevent displacement of the plate. Also, the sealing body is ventilated to facilitate compression and expansion.

Abstract: A dock seal for use around a building doorway against which any of various style trucks can back to create a totally-sealed, safe, dry passageway. It includes several sections around the building doorway each having a sealing body of resiliently flexible and compressible foam material of L-shaped cross-section enclosed in a thin flexible cover. The sections are so arranged that as the truck backs into cooperation with the doorway, a part of its rear edge engages the flexible flange of each seal section so that an effective seal will be created around the truck. This also creates a totally safe dry passageway for loading or unloading. The seal body cover is provided with ventilating means to facilitate compression, bending and expansion of the body and stiffening means where needed. Means is also provided for mounting the seal body for ready removal and replacement.
