  • Patent number: 6568534
    Abstract: A pan for use with a well for receiving the pan is disclosed herein. The pan includes a bottom panel, a plurality of walls, and a ramp. The plurality of walls extend upwardly from the bottom panel and define a cavity. The plurality of walls also have an upper end which defines a top opening. The upper end has an extension away from the cavity which defines a rim. The ramp is proximate the rim and exterior to the cavity, whereby the pan rides up on the ramp when the pan is drawn up against the well.

  • Patent number: 6460453
    Abstract: A covering system includes a frame, a cover pivotally coupled to the frame and a stop surface pivotally coupled to the frame. The cover pivots between a closed position, a substantially open position and at least one intermediate position. The stop surface pivots between a first position in which the stop surface engages the cover when the cover is in the at least one intermediate position to retain the cover in the at least one intermediate position and a second position permitting the cover to be pivoted to at least one of the substantially open position and the closed position. The stopper includes a counterweight which biases the stop surface towards the first position as a result of gravity.

  • Patent number: 6213483
    Abstract: A utility cart is presented having improved assembleability, economy, rigidity and stability. In one feature, the cart includes a wheeled frame having a shelf supported by the frame. The shelf includes a movable surface and the frame includes a retention surface. The movable surface moves between a position of out of engagement with the retention surface and a position in engagement with the retention surface. This structure allows the shelf to snap into place without the need for separate mechanical fasteners. According to another feature, the cart includes a top shelf configured to deflect U-shaped leg members inward to apply a binding force upon the bottom shelf. According to a third feature, the cart includes a cross member connecting two leg members, the cross member having L-shaped slots to receive protuberances on the leg members.

  • Patent number: 6117069
    Abstract: The present invention relates to a non-invasive penile erection device having a constrictor ring designed to fit against the base of a male genital or penis, and a diaphragm seal that forms a substantially air tight seal against the constrictor ring. The constrictor ring is designed to comfortably and securely fit the base of the penis. The substantially air tight seal enables the pump to produce vacuum pressures of over 17 inches of mercury. The diaphragm seal is designed to collapse around the constrictor ring and remain on during sexual activity. The diaphragm seal cooperates with the constrictor ring to apply pressure to the surface of the penis. The placement of the constrictor ring on the base of the penis and the greater vacuum pressure achieved by the device tend to draw the root or "oz" of the penis into the constrictor ring so that a more natural erection is achieved and maintained after the vacuum tube is removed.
