Patent number: 6648348Abstract: A ski-snowboard device has a support board for the user and a plurality of ski pairs mounted to the underside of the board. The ski-snowboard has a steering and suspension system, connecting the skis in each pair, to provide paired steering and independent suspension. Each steering and suspension system preferably comprises two pivoting generally-V-shaped arms connecting the board to the skis, wherein the V-shaped arms are spaced apart at their top end connections to the board, and each connect to different portions of rocker members that hold the skis. The V-shaped arms pivot relative to the board, and the rocker members pivot relative to the arms and also relative to the skis. Shock-absorbing/biasing systems cushion vibrations and tune the suspension and steering. Thus, the skis move right and left, move to their inside edges, and swing forward and rearward, to properly steer the ski-snowboard right and left and up and down terrain, for enhanced handling and control by the user.Type: GrantFiled: September 13, 2001Date of Patent: November 18, 2003Inventor: Mark Link

Patent number: 6575479Abstract: A three runner sled includes a single steerable front runner and two directionally fixed rear runners extending from a frame. The frame has a longitudinal backbone member with an elongate seat. Each rear runner has a knee rest somewhat forwardly positioned relative to the seat. Each rear runner also has a foot rest at its rearward end. This configuration results in a kneeling position for the sled operator, providing a relatively low center of gravity for the sled and operator, yet allowing the operator to readily shift his/her weight laterally for better balance and control. The telescoping steering column connecting the front runner to the sled frame includes an adjustable suspension. Independently actuated brakes are provided at the rearward ends of the rear runners, controlled by separate brake levers. Attachments may be provided for carrying the sled on a person's back, for convenient sled transport.Type: GrantFiled: July 9, 2002Date of Patent: June 10, 2003Assignee: Triage Sled Works, Inc.Inventor: Andrew S.

Patent number: 6431561Abstract: A snowmobile having asymmetrical, high floatation skis. The snowmobile includes left and right steerable skis carried by a front suspension system that in turn is mounted to the snowmobile's chassis. Each ski has a downwardly extending longitudinal keel, and inner and outer floatation portions extending laterally from the keel. The inner floatation portion of each ski is wider than the outer floatation portion of such ski, making the ski asymmetrical with respect to the keel and giving the ski greater floatation without increasing the overall width of the snowmobile. Preferably the front suspension system includes left and right generally downwardly and forwardly extending spindles, each spindle carrying at its lower end the corresponding ski. The spindles define the steering axes for their respective skis. Preferably the steering axis of the spindle passes through the keel.Type: GrantFiled: November 3, 1999Date of Patent: August 13, 2002Assignee: Polaris Industries Inc.Inventor: Jan M. Hedlund

Patent number: 6367820Abstract: A snow board with a ground contacting surface having a bulbous area at the forward end of the board and two ridges extending along from the bulbous area toward the rear end of the board. Each ridge is close to one edge opposite the other ridge and is curved convexly toward a centerline of the board. The rider, sitting or kneeling on the board while sliding downhill, can lean forward so that the bulbous forward area is supported by the slippery surface and in this position, the rider can cause the board to “spin ”. In another mode, the rider shifts his weight rearwardly so that the ridges are in contact with the ground. By leaning to one side or the other, the respective ridge contacts the ground and the shape of the ridge causes the board to turn.Type: GrantFiled: September 9, 2000Date of Patent: April 9, 2002Inventor: Warren Herndon

Patent number: 6279925Abstract: A method and apparatus for providing a sled having independently steerable skis is provided. The apparatus provides a sled having skis that move in three distinct directions in response to a single control input. Each of the skis is independently controlled, and can be used in combination or individually to control the movement of the sled. The sled may be provided with a seat for carrying a human occupant, or alternatively may be remotely controlled using extended levers, or servo motors operated remotely, such as by a radio frequency remote controller. The method of the present invention comprises controlling a sled by providing a control input to a first ski of a sled, wherein the control input simultaneously pushes down the ski in relation to the frame, rotates a forward end of the ski towards the center of the sled, and rotates the ski about its longitudinal axis such that an outside edge of the ski moves towards the frame of the sled and an inside edge of the ski moves away from the sled.Type: GrantFiled: July 21, 1999Date of Patent: August 28, 2001Inventor: Bart W. Miller
