In this manner, the seal (12) is secured to the retainer (10) and the retainer (10) is then secured to the garage door (16) without the use of any tools or fasteners.

Abstract: A foldable dry erase surface, such as a temporary wall, permits writing on the surface as is typically done with a dry erase board. The dry erase surface includes individual panels that are hinged together so that the surface formed by the panels is foldable. The individual panels have a dry erase film attached to them so that writing may occur on the panels themselves. The dry erase surface may be collapsed when not in use, or it may be expanded when it is necessary to write on or read from the surface. The dry erase surface is collapsed or expanded by pivoting the panels about the hinged connections, which is typically done by pushing or pulling an end panel of the dry erase surface.

Abstract: A tear-resistant flexible hinge structure is placed between a pair of substantially rigid panels so as to permit the panels to be hinged one with respect to the other, where the flexible hinge is formed from a plastics material such as polyvinyl chloride. The hinge structure is formed under heat and pressure so as to comprise at least three parallel rows of alternating flat and raised portions, in staggered relationship. This causes a structure whereby any rip or tear which starts in the formed flexible hinge cannot continue because it will encounter a discontinuity in the configuration and thickness of the material, which precludes further propagation of the rip or tear. Typically, after the hinge structure has been formed, it is configured in a semi-circular cross section, re-heated and cooled, so as to set and have a memory in its closed configuration as opposed to the originally pre-formed flat, open configuration.
