  • Patent number: 7021636
    Abstract: A typically one-rider non-powered sports/recreational vehicle has a main body that can be easily converted between a wheeled coaster-wagon configuration and a snow-sled configuration with runners. Typically there are four wheels or four runners: two at front, steerable from a handlebar, and two fixed at rear. For braking in the coaster-wagon configuration, a pair of brake shoe pads, attached to the handlebar, press against the front tires to act as brake shoes when the handlebar is twisted radially via a pair of user handgrips. In the snow-sled configuration, a braking panel, attached centrally on the handlebar, moves downwardly to brake by engaging oncoming snow. In normal use as a coaster or sled, when not braking, this braking panel is nested in an unobtrusive location immediately beneath the front of the main body platform, retained there by spring action that also provides braking hold-off in the coaster-wagon configuration.

  • Patent number: 6708989
    Abstract: The new skis for converting a wheeled push vehicle into a slidable push vehicle have a front anchor on their upper surfaces at a location proximate to the toe end and a rear anchor on their upper surfaces at a location proximate to the heel end. A flexible front harness assembly is attached to the front anchor, and a flexible rear harness assembly is attached to the rear anchor. The distance between the front anchor and the rear anchor is such that any aligned fore and aft wheel assemblies of a wheeled push vehicle to which the ski is capable of being attached can be positioned on the upper surface of the ski between the front and rear anchors to permit the front and rear harness assemblies to draw the fore and aft wheel assemblies away from each other and in a downward direction on the ski. A simple strap can serve as a harness assembly.

  • Publication number: 20010028155
    Abstract: A gravity driven steerable vehicle having wheels, or skis or a combination of wheels and skis for recreational use, most particularly on surfaces such as pavement, artificial hard-pack turf, mountain slopes, dirt roads, grass and hard-packed or non-packed snow. The vehicle has at least three (3) but preferably four (4) wheels, or skis or a combination of wheels and skis which may or may not be on independent axles one from the other and which may or may not be each independently shock suspended. There is also a steering mechanism for steering the vehicle and a driver compartment portion for containing a driver of the vehicle in a prone face-down and face-forward position. The vehicle is steerable by the driver from the prone face-down and face-forward position. The mechanism for suspension of the wheels and/or skis is configured to provide precise control in turns especially the carving of turns, by the skis, while descending on snow covered terrain.

  • Patent number: 6139029
    Abstract: A multipurpose two-wheeled cart whose wheels are removable from the body of the cart to leave a generally planar flat bottom, so that the cart can be used as a sled. Side extensions may be mounted to hold bulky loads. Removable handles are provided at both of the sloping ends of the body and are adjustable to keep grips at the same height from the ground when the wheels are removed. Either or both of the handles may be mounted and used, depending on whether terrain and load make it desirable for one person or two people to move the cart and its load. The handles, wheels, and side extensions all fit within the body to provide a compact unit for transport in a motor vehicle. Stiffeners on the bottom of the body may be used as runners.

  • Patent number: 6126377
    Abstract: Interlocking towing skates for placement beneath the tires of a vehicle prior to winching onto a flatbed. Two or more skates can be locked together in accordance with the tire width of the vehicle to be towed, and the interlocked skates are placed beneath each tire. The disabled vehicle can be winched quickly and easily upward along the flatbed. The friction of the tires is greatly reduced as the salvage vehicle is drawn upward, and personal injury and/or damage to the transmission and/or tow truck hoist is eliminated. The towing skates are formed as an elongate hard unitary plastic member having a chock at one end, a flat mid-section, and an opposing ramped end. A series of interlocking teeth protrude laterally from one side, and a mating series of interlocking recesses are formed in the other side for locking side-by-side skates together.

  • Patent number: 6032962
    Abstract: A skate assembly that includes a rigid runner plate mounted perpendicularly to the underside of a boot. The runner includes one or more cutouts where wheel or roller assemblies are rotatably mounted. The roller assemblies lowermost tangential edge is aligned with the bottom edge of the runner. The roller members for the respective roller assemblies include serrations on their periphery. The result being to lower the overall friction of the edge by reducing the effective contact area of the edge with the skating surface by introducing the cut-outs with roller members providing a support point in the middle of the cut-out.

  • Patent number: 5794291
    Abstract: A ramp for loading and unloading snowmobiles and other vehicles from a load bed such as a trailer or transport vehicle. The ramp comprises a pair of longitudinal tracks joined by a plurality of transverse members. Such transverse members are adapted to receive the wheels of the objects being transported or, in the case of snowmobiles, the belt grip thereof. In the case of snowmobiles, the skis of such vehicle are received on the longitudinal tracks. The ramp includes a pair of wheels for use in moving the ramp across the load bed. The wheels are positioned at a location on the ramp corresponding to the center of mass of such ramp when supporting the snowmobile or other such vehicle. The tracks of the ramp are preferably angled upwards to avoid contact with the load bed when being moved across same. The spacing of such tracks is adjustable so as to permit transport of the vehicles having a variety of widths.
