Abstract
A bottom seal for an L-shaped dock shelter pad is tapered upwardly in the general form of a pyramid and is positioned in tight-fitting relation to the inner corner of the L-pad. The sloped upper surface of the bottom seals's compressible, resilient core and covered with a flexible, water-repellent, wear resistant material, while its bottom surface is covered with mesh material which allows for drainage/drying of the pad core and allows it to 'breathe'. The top corner of the bottom seal is coupled to the L-pad's inner corner to prevent sagging of the bottom seal, while one of its lower corners is also coupled to the L-pad's inner corner to maintain intimate contact between pad and seal even when engaged and compressed by a vehicle. The sloped upper surfaces of the bottom seal prevent debris from collecting within the L-pad while its upwardly tapered shape allows the bottom seal to fill the entire gap between the L-pad and adjacent wall regardless of the extent to which the L-pad is deflected or bent. Its tapered shape allows the bottom seal to provide decreasing resistance to flexure of the L-pad in an upward direction when the L-pad is engaged and deflected.
