  • Patent number: 6645031
    Abstract: A children's playboard of the type comprising a backing having a front surface of a cloth material for adhering figurines thereto and a back surface is disclosed. The children's playboard has a support structure. The support structure is fixedly attached to the playboard and has a pair of spaced bracing members and a pair of connection plates. Each bracing member has a first leg that is detachably joined to one of the pair of connection plates along a hinge. The bracing members are extendable at an angle from the playboard. The bracing members have a second leg and a third leg that are joined at an apex portion. The second leg having a greater length than the third leg. The apex is located between the second and third legs and provides support for the bracing members against a base surface wherein the backing member can be supported in at least two different angles to the base surface.

  • Patent number: 6312311
    Abstract: The present invention provides a water tower generally having a base portion, a tower support attached to the base portion, and a fluid vessel attached to the tower support and containing a fluid. A buoyant vessel having a first magnet attached is contained within the fluid vessel. A first arm defining a cam slot and rotatably attached to the tower support by a first pivot pin guides a second arm, an end of which is disposed within the cam slot. The second arm is rotatably attached to the tower support by a second pivot pin. A second magnet is attached to a second end of the movable arm. In operation, the first arm is rotated to move a second arm, bringing the first and second magnets into alignment. The magnets create an attraction force which sinks the buoyant vessel within the fluid, giving the water tower the appearance of being full. When the first arm is rotated so magnets are taken out of axial alignment, the attraction force of the magnets is diminished, and the buoyant vessel floats.
