  • Patent number: 4434829
    Abstract: The collapsible yard pan has a rigid frame covered with a pliable fabric or plastic film material contoured to form a portable bag container that can be opened along one side and an end which can lie flat for easy filling. The frame is typically a rectangular shaped double sided structure with two rigid primary side or top members supporting the opening edges of the bag. These two primary side members are hinged at the closed end of the bag, typically to a frame member that supports the bag closed end. This closed end member may be connected to a single rigid closed side or bottom edge support member. The edges of the open end of the bag are typically supported by either rigid or semi-rigid slats that assist in holding the bag end closed when the bag is closed. The slats on the leading edge of the bag also facilitate filling when loose material such as leaves or grass are raked or pushed into the open bag.

  • Patent number: 4317344
    Abstract: A pair of anti-dust and anti-moisture protective cover boots fabricated of a resilient and pliable soft molded material such as polyurethane plastic, or the like, to respectively fit snugly over the shackle bight, shackle legs and adjacent top end of a padlock case, and also to fit over the cylinder/key end or lower end of the case. The top cover boot for the shackle end is provided with spaced holes to snugly accommodate the legs of the shackle, and has a self-closing slit interconnecting the spaced holes to permit the boot to be yieldingly slipped snugly over the shackle and onto the adjacent end of the case. The other generally similar bottom boot has a shorter, angularly disposed self-closing slit provided generally centrally in its end wall to provide key access. The plane of the slit is disposed obliquely relative to the inner and outer surfaces of the end wall to reduce likelihood of entry of moisture and dust.
