  • Patent number: 6321903
    Abstract: Splice joint for plastic coated fabric conveyor belt or similar article which initially provides a mechanical bond between the two (2) conveyor belt ends to be joined prior to a vulcanization process. This is achieved by providing a “jig-saw puzzle” splice between the two (2) conveyor belt ends to be joined wherein at least one of the conveyor belt ends to be joined has outwardly extending mushroom shaped or arrow-head shaped tabs and the other conveyor belt end to be joined has corresponding inwardly extending sockets to provide both increased splice joint surface area, as well as a mechanical bond, between the two (2) conveyor belt ends to be joined.

  • Patent number: 5647072
    Abstract: A foot support device is adapted to mount in a corner formed by the walls of a shower area in order to support the foot and leg of a bather for washing or shaving the leg. The foot support device includes a shelf panel that is supported approximately twenty to sixty centimeters above the shower base and is preferably oriented at an oblique angle of between 15.degree. and 30.degree. to the base. A mounting structure mounts the shelf panel to the walls and includes a pair of mounting panels that confront the walls. Preferably, the shelf panel and the mounting panel are formed as a crescent-shaped, integral piece of molded plastic, and the mounting panels are hinged along linear regions of reduced thickness that define lateral side edges for the shelf panel. Drain openings are formed through the shelf panel, and reinforcing ribs extend around these openings. Reinforcing lips extend along the front and rear edges of the shelf panel and also provide limit stops to help position the mounting panels.
