  • Patent number: 8499899
    Abstract: A wheel chock system for preventing movement of one or more wheels. The system may include a pair of chocks for clamping onto one or more wheels. The chocks may be connected through a linkage mechanism that can be rotated to draw the chocks together or move the chocks further apart. A handle may be attached to the linkage mechanism for moving the chock system from a blocking position to a released position. The handle may be configured to stand upright such that the chock system can be installed and removed by a user in a standing position without the need to bend or crouch. One embodiment of the chock system may be attachable to two different wheels in a tandem wheel arrangement, whereas another embodiment of the chock system may be configured to clamp onto a single wheel.

  • Patent number: 8002241
    Abstract: The present invention is a unitary piece block formed of polymers (such as polystyrene or other high strength polymer) by a single injection molding step which are assembled into a recreational vehicle leveler. The invention ramp provides four sets of four connectors at a top of a floor plate, which are adapted to interlock in cavity structures formed within a cavity on the underside of the block. Two adjacent blocks are secured together by applying to their top surfaces the securing cavity structure of an underside of a third such block. Such blocks can be stacked in an interlocking manner to reduce storage space.
