  • Patent number: 6554243
    Abstract: A rollable sports ballast base for supporting a sports apparatus support member comprising a base member having a top and bottom surface. The bottom surface contacts a support surface such as a driveway or other playing surface. There is at least one wheel assembly, retractable from a lowered position to a raised position. The wheel assembly includes a pivoting connector coupled to the base member and a wheel bracket coupled to the pivoting connector. The wheel bracket includes an axle, at least one wheel, and a handle extending outwardly from the wheel bracket. The handle is used to pivotally rotate the wheel assembly about a transverse axis. When the handle is rotated away from the base member, the wheel assembly is placed in a lowered position whereby the wheel contacts the support surface thus separating the bottom surface of the base member from the support surface.

  • Patent number: 6485269
    Abstract: A detachable air compressor system includes a detachable air compressor unit and a second storage tank. The detachable air compressor unit is portable and includes an air pump powered by a motor and connected to a first storage tank, where the pump, motor, and first storage tank are all connected to a first base. The first storage tank is also attached to a regulator in order to release the compressed air stored inside and to a first coupler to permit the transport of compressed air between the first storage tank and the second storage tank. The detachable air compressor unit can be attached to a second storage tank of a larger size than the first storage tank. The second storage tank includes a second coupler adapted for receiving the first coupler from the first base as well as a second base adapted for coupling with the first base to removably secure the detachable air compressor unit to the second storage tank.

  • Patent number: 6427963
    Abstract: A rollable sports ballast base for supporting a sports apparatus support member comprising a base member which has a first edge and a second edge, a top surface and a bottom surface. The bottom surface is adapted to contact a support surface such as a driveway or other playing surface. There is at least one wheel assembly for contacting the support surface. One of the wheel assemblies is retractable from a lowered position to a raised position such that when in the raised position, the bottom surface of the base member substantially contacts the support surface. In the lowered position, both wheel assemblies contact the support surface thereby separating or elevating the base member from the support surface. In another embodiment, the invention consists of a similar rollable sports base for supporting a sports apparatus support member wherein one wheel assembly is retractable and comprises a pivoting connector coupled to the base member and a wheel bracket coupled to the pivoting connector.

  • Patent number: 6352183
    Abstract: An undersink water delivery system that includes a housing for holding a container of water and a pump for delivering water to an air gap type faucet. The housing includes a pivotally mounted access door that assists a user in loading a container of water. The access door includes a water delivery coupling that is connected to the pump to deliver water from the container to the faucet. To load a container of water the access door is pivoted to the open position and a container of water is slid into a cradle formed in the access door until the neck of the bottle engages the water delivery coupling. The access door is pivoted upwardly (including the container of water) into the closed position. The access door thereby functions as a lever assisting a user in loading a container of water into the housing.
