Abstract
A summer style ski having three different types of wheels aligned to allow the ski to travel on non-snow or ice surfaces and to create the feel of carving or turning on a paved surface.
Claims17
A wheeled ski comprising a base, a binding, and three different wheel types, arranged along the length of the ski:
- a. Wherein the base is a flexible member having a length, a width, and edges, with the length being several times greater than the width;
- b. wherein the binding is centrally located along the longitudinal axis of the base, and the three wheel types have a having a mirror image wheel type on either side of the binding;
- c. wherein extending away from the binding along the longitudinal axis in each direction is a pair of fixed wheels having a fixed axle mounted to the base, and the wheels, mounted on said axle and extending away from the base along the lateral direction, where the wheels can rotate along a rotational axis and allow the ski to move along the longitudinal axis;
- d. extending further to the end of the ski from the fixed wheels are corresponding pairs of moveable axle wheels, having a binding with an axle positioned along the lateral axis and wherein the axle can move horizontally;
- and
- e. wherein, the outermost wheels are single caster wheels positioned at each end of the ski, and mounted on a Z-shaped mount.
A wheeled ski comprising a base, a binding, a pair of caster wheels, two pairs of moveable axle wheels, and two pairs of fixed axle wheels each arranged along the longitudinal axis of the base;
- a. wherein the base has a length, a width, a left edge, a right edge, a top, a bottom, a front and rear tip, and two cutout portions;
- b. wherein connected to each of the front and rear tip is a caster support member having a Z shape, wherein one side of the Z shaped member is connected to a portion of the top of the base at the front and rear tips, and the other end of the Z shaped member is positioned above the base and extends past the tip to be about parallel to the base;
- the end extending past the tip comprises a pivot member and attached to the pivot member is a caster and attached wheel, which is positioned on the underside of the end of the Z shaped member extending past the tip;
- c. adjacent to the Z shaped member and positioned towards the center of the base along the longitudinal axis on each end, is a pair of adjustable axle wheels;
- wherein the adjustable axle is connected to a mount which is connected to the base and the axle extending along the lateral axis;
- wherein wheels are attached to each side of the axle and extend beyond the left and right edges of the base;
- d. positioned within the two cutout portions of the base are two pairs of fixed axle wheels, wherein the fixed axle is secured to the base and positioned such that the axle is along the lateral axis and parallel to the adjustable axles;
- wherein the wheels are engaged to the axle and a portion of the wheel extends past the edges of the base;
- e. about centrally positioned on the base, and between the fixed axle wheels, is a binding;
- and
- f. wherein the three different types of wheels have varying vertical clearance with respect to the bottom base;
- wherein the fixed wheels have the smallest clearance between the bottom of the wheel and the bottom of the base;
- the adjustable wheels having the next smallest clearance;
- and the caster wheels on each end having the greatest distance between the bottom of the wheel and the bottom of the base;
- whereby when the ski is placed on a surface, only the caster wheels are therefore necessarily touching the surface.
A wheeled ski comprising three sets of wheels, a binding, and a base;
- wherein the first type of wheel is a freely rotating wheel;
- with one freely rotating wheel attached to a support member at each end of the longitudinal axis of the base;
- attached adjacent to the freely rotating wheels on each end are a pair of movable axle wheels, wherein the axle is oriented along the lateral axis and having a rotational axis such that the wheel attached to the axle will move the ski along the longitudinal axis;
- attached between the pair of movable axle wheels on each end is a pair of fixed axle wheels, with the axle aligned along the lateral axis and parallel to the other axles;
- and centrally located is a binding that is situated between the two pairs of fixed axle wheels;
- wherein each of the three types of wheels has a different amount of clearance from the bottom of the wheel to the bottom of the base, wherein the freely rotating wheel has the greatest clearance, the movable axle wheels the next greatest clearance, and the fixed axle wheels the least clearance;
- and wherein each wheel has a different lateral distance from a center line of the base, with the freely rotating wheel being along the center line, the fixed axle wheels extending to no more than one half of the width of the wheel past the edge, and the movable axle wheels extending more than one half of the width of the wheel beyond the edge.
