Patent number: 5503242Abstract: A propeller driven vehicle for traversing snow and ice covered terrain with improved steering response and stability. The vehicle has a motor driven propeller providing motive force to sustain forward motion of the vehicle regardless of terrain conditions. The vehicle rides on four skis which greatly enhance the stability of the vehicle and prevent the likelihood of tipping during sudden and severe turning. A parallelogram suspension system provides maximum contact between the skis and the terrain while allowing the skis to respond to vertical undulations in the terrain. A foot operated drag brake is mounted in the rear of the vehicle to decelerate the vehicle.Type: GrantFiled: September 27, 1994Date of Patent: April 2, 1996Inventor: Terry E. Jeffers

Patent number: 5443278Abstract: A snowmobile steering ski or skis, which may be equipped with a ski liner to prevent undue drag on a snowmobile snow, includes a integral fin that enhances steering control in turning or resisting sidehill slippage of the snowmobile particularly in traversing powder or hard packed. The ski liner fin is integral, or replaceable, and extends outwardly along the outer edge and downwardly over a central portion of the ski. The fin contacts the snow on the inner side of either a flat turn, or the uphill slope of a sidehill run, because the forward end of the snowmobile ski is cambered so as to tip downwardly toward the steered direction of a turn.Type: GrantFiled: September 16, 1993Date of Patent: August 22, 1995Inventor: Joseph J.

Patent number: 5335925Abstract: In a ride-on snow sled of the steerable type, a pair of support side runners are fixedly attached to fore and aft vertically oriented legs. The legs are adapted to slide up and down within hollow tubular frame members. The upper ends of the front legs of each runner are attached to one another by a non-compressible and non-extendible cable member. Similarly, the rear pair of legs are connected through a rear tubular frame. Thus, a shift of weight causing the right ski to extend downwardly from the frame causes a proportional lift or rise in the left ski such that the legs on the left ski retract into the frame. With the skis at different heights proportionate to the slope of the hill, an edging effect is created, permitting the operator to traverse the hill without sliding in much the same manner as a skier traverses a hill.Type: GrantFiled: December 21, 1992Date of Patent: August 9, 1994Inventor: Murray Dolson

Patent number: 5038882Abstract: An improved spindle arrangement for a suspension system for supporting skis of a snowmobile induces a steering bias in each of the respective skis. A spindle is attached to respective upper and lower linkages of unequal dimensions by ball joints. The ball joints attached at each respective spindle are offset from the longitudinal axis of the spindle in a manner such that a bias is induced in each respective ski causing it to toe-out. Accordingly, the bias induced in the skis creates a situation wherein the snowmobile will give the rider much more confidence and a more comfortable ride when operating the snowmobile at high speed by eliminating the disconcerting feeling that can be generated when the skis tend to toe-in.Type: GrantFiled: March 12, 1990Date of Patent: August 13, 1991Assignee: Arctco, Inc.Inventor: Dennis P.

Patent number: 4667975Abstract: A hand-powered toy vehicle with a pair of levers coupled to independent rear wheels. The levers can be operated together to accelerate forward movement of the vehicle, as well as to brake it.

Patent number: 4192395Abstract: A vehicle, especially an amusement vehicle, in which a frame having a seat adapted for seating two occupants is located within the radial confines of a pair of relatively large coaxial spaced wheels. The frame includes rollers mounted thereon and distributed circumferentially about the inwardly facing annular surfaces of the larger wheels and engaging the same so as to rotatably support the frame within the wheels. A pair of relatively large chains are mounted circumferentially on the respective wheels within the radial confines thereof concentrically with the common axis of the wheels and are driven by crank driven sprockets carried by the frame to thereby propel the vehicle. The center of gravity of the frame, including any occupant therein, is below the common axis of the wheels so that when the sprockets are driven, the frame will first move within the wheels to create an unbalanced condition in the vehicle and the wheels will then commence rotation thereby causing the vehicle to move.Type: GrantFiled: March 17, 1978Date of Patent: March 11, 1980Inventor: Gerald L.
