Abstract
The invention relates to a roller ski having a suspension system incorporated into the front and rear regions of the main roller ski body. The suspension system allows roller-skiers to undertake roller-skiing on rougher pavement, asphalt or the like by reducing stress and/or discomfort to the roller-skier. In addition, the suspension system provides a skiing experience that more closely resembles skiing on snow by returning energy back to the skier in a manner similar to the effect that the camber of a snow ski provides to the skier. In addition, in one embodiment, the roller ski also includes a pressure sensitive ratchet system that simulates skiing using classical technique.
Claims22
A roller ski comprising:
- a main body operatively supporting a front wheel and a rear wheel;
- a first suspension system connected to the main body and the front wheel;
- and,
- a second suspension system connected to the main body and rear wheel;
- the first and second suspension systems each including a suspension arm having a wheel end for connection to the front or rear wheel and a suspension end wherein the suspension end is pivotally retained within the main body at a pivot point between the wheel end and suspension end, and wherein each suspension arm is operable between a neutral position and a deflected position against a bumper retained between the suspension end of each suspension arm and the main body and wherein the suspension system dampens vibration between the front and rear wheels and the main body during use.

- a second suspension system connected to the main body and rear wheel;
- the first and second suspension systems each including a suspension arm having a wheel end for connection to the front or rear wheel and a suspension end wherein the suspension end is pivotally retained within the main body at a pivot point between the wheel end and suspension end, and wherein each suspension arm is pivotable about a shaft secured to the main body between a neutral position and a deflected position against a deformable elastomer bumper retained between the suspension arm and the main body;
- and
- a pre-load plate operatively connected between the shaft and main body, the pre-load plate having a bumper surface for engaging with the bumper and a shaft surface for engagement with the shaft;
- wherein the suspension system dampens vibration between the front and rear wheels and the main body during use.
