Abstract
A drum brake design is applied to an in-line skate wheel having a circular braking surface located on an inner race. A brake shoe is pivotally mounted to a frame member. An activating end of the brake shoe is linked to the rotatable upper boot quarter. The skater activates the brake by rotating the upper boot quarter rearward. Alternate embodiments include multi-wheel brakes and a remote transmitter which activates a frame mounted electric actuator.
Claims16
A skate wheel brake comprising:
- a boot rigidly mounted on a frame to reduce relative
- movement of said boot and said frame;
- a wheel on the frame having a radially inwardly facing surface;
- said radially inwardly facing surface further comprising a braking surface;
- a brake shoe having a brake pad;
- said brake shoe further comprising a pivoting end having a hinged attachment to a support means, thereby holding the brake pad juxtaposed the braking surface;
- said brake shoe pivoting in a plane parallel to a central plane of the wheel;
- and
- said brake shoe further comprising an activating end having a pivotal attachment to an activator means,
- whereby the activator means controllably moves the activating end toward and away from the braking surface, thereby generating a braking force on the wheel when they brake pad presses against the braking surface.
A drum brake for an in-line skate having a plurality of wheels, said wheels having axles which are supported by a frame, said drum brake comprising:
- at least one wheel having a radially inwardly facing braking surface, said braking surface generally comprising a circular braking surface;
- a brake shoe having a pivotal mounting means and having a pivot plane substantially parallel with a central plane of the wheel;
- said brake shoe having a brake pad and an activating end;
- and
- an actuator means pivotally mounted to and functioning to press the activating end toward said circular braking surface, thereby causing the brake pad to apply a braking force to the wheel.
A skate wheel brake comprising:
- a boot rigidly mounted on a frame to substantially prevent relative movement of said boot and said frame;
- at least two wheels having tires disposed on said frame, at least one of said wheels having a radially inward facing braking surface;
- said radially inward facing braking surface disposed at least partially within the width defined by the tire of said wheel;
- a brake shoe having a brake pad;
- said brake shoe comprising a pivoting end hingedly attached to a support means, thereby holding the brake pad juxtaposed said radially inward facing braking surface, and an activating end pivotally attached to an activator means;
- said brake shoe pivoting in a plane substantially parallel to a central plane of the wheel;
- whereby the activator means controllably moves the activating end toward and away from said radially inward facing braking surface to apply the brake pad to at least a portion of the braking surface within the width of the tire, thereby generating a braking force on the wheel.
A skate wheel brake comprising:
- a boot mounted on a frame;
- a wheel on the frame having radially inwardly facing surface;
- said inwardly facing surface further comprising a braking surface;
- a brake shoe having a brake pad;
- said brake shoe further comprising a pivoting end having a hinged attachment to a support means, thereby holding the brake pad juxtaposed the braking surface;
- said brake shoe pivoting in a plane substantially parallel to a central plane of the wheel;
- and
- said brake shoe further comprising an activating end pivotally attached to an activator means,
- whereby said hinged attachment and said activating end are positioned relative to the axle of said wheel to create a mechanical advantage between said brake pad and said braking surface when the brake pad presses against the braking surface which reduces the amount of activating force needed to stop the wheel.
