Abstract
A two-wheeled roller skate with canted wheels has an axle for the forward wheel located well forward of the ball of the foot. The axle for the rear wheel is located at the rear of the skater's heel. The wheels are canted so that the front and rear wheels contact the ground on the opposite sides of the center line of the skater's foot. In plan projection, the axles are preferably non-parallel in order to provide steering correction. The amount of steering correction desirable will depend on the skater's skill and the nature of the skating activity. In alternative embodiments, the present invention incorporates novel braking mechanisms.
Claims34
A roller skate comprising:
- a boot having a toe portion and a heel portion, both the toe and heel portions being generally bisected in plan view by a longitudinal center line of the boot defining an inside direction and an outside direction;
- a front wheel rotatably mounted to the toe portion of the boot and disposed to the outside thereof for rotation about a first axis inclined with respect to horizontal;
- a rear wheel rotatably mounted to the heel portion of the boot and disposed to the outside thereof for rotation about a second axis inclined with respect to horizontal;
- said front and rear wheels supporting the boot above a ground surface, said front and rear wheels contacting the ground surface on opposite sides of the longitudinal center line.
A roller skate comprising:
- a boot having a toe portion and a heel portion, both the toe and heel portions being generally bisected in plan view by a longitudinal center line of the boot defining an inside direction and an outside direction;
- a front wheel rotatably mounted to the toe portion of the boot and disposed to the outside thereof for rotation about a first axis inclined with respect to horizontal;
- a rear wheel rotatably mounted to the heel portion of the boot and disposed to the outside thereof for rotation about a second axis inclined with respect to horizontal;
- wherein at least one of the first and second axes is at an oblique angle with respect to the center line in plan view.
A roller skate comprising:
- a chassis;
- a plurality of wheels rotatably mounted to the chassis, at least one of said plurality of wheels having a braking surface;
- a brake shoe movably coupled to the chassis for intermittent operative engagement with the braking surface;
- a lever having a proxinal end operatively coupled to the brake shoe and a distal end extending from the chassis, said lever pivotally mounted on the chassis such that an upward force on the distal end causes the brake shoe to engage the braking surface.
A roller skate comprising:
- a boot having a toe portion, a ball portion and a heel portion;
- a front axle mounted to the toe portion having a first axis inclined with respect to horizontal, said front axle disposed entirely forward of the ball portion;
- a front wheel rotatably mounted on the front axle to an outside of the boot;
- a rear axle mounted to the heel portion having a second axis inclined with respect to horizontal;
- and
- a rear wheel rotatably mounted on the rear axle to the outside of the boot.
A roller skate comprising:
- a boot having a sole, a toe portion, and a heel portion, a front axle mounted to the toe portion having a first axis inclined with respect to horizontal, said front axle disposed entirely below the sole of the boot;
- a front wheel rotatably mounted on the front axle to an outside of the boot;
- a rear axle mounted to the heel portion having a second axis inclined with respect to horizontal;
- and
- a rear wheel rotatably mounted on the rear axle to the outside of the boot.
A roller skate comprising:
- a boot having a sole, a toe portion, and a heel portion;
- a front axle mounted to the toe portion having a first axis inclined with respect to horizontal;
- a front wheel rotatably mounted on the front axle to an outside of the boot;
- a rear axle mounted to the heel portion having a second axis inclined with respect to horizontal, said rear axle disposed entirely above the sole of the boot;
- and
- a rear wheel rotatably mounted on the rear axle to the outside of the boot.
