  • Patent number: 6625950
    Abstract: A wall protector includes a retainer that is adapted to be attached to a building wall and a cover of an impact resistant thermoplastic polymeric material in the form of a thin web of suitable cross-section attached to the retainer portion of the retainer. The cover includes at least one substantially straight portion of substantially uniform cross section along its length and having a face portion overlying the retainer and an integral transition portion that is integral with the straight portion has an end wall that curves smoothly away from the face portion of the straight portion from a rounded juncture with the face portion and overlies and conceals the end of the retainer. The integral transition portion may be configured as an end cap or a wall return piece that forms a transition between the straight portion and a wall surface or as a corner piece that joins sections of wall protectors mounted on walls that intersect at a corner.

  • Patent number: 5536160
    Abstract: A solidifying liquid is placed into a mold having sides and a planar bottom. A plurality of separators are attached to the bottom of a support grid. The support grid is then placed onto the mold, with positioning projections extending through holes in the support grid. The liquid is then allowed to set, forming a work surface having a flat top surface and support ribs on its bottom surface.
