Claims
- 1. A roller skate brake system for connecting to a roller skate, said roller skate having a back axle and a toe portion, and said brake system comprising:
- (a) a brake carriage having a first arm, a second arm, and a back member connecting said first arm and said second arm, said first arm having a pivot point, and said second arm having a pivot point opposite said pivot point of said first arm, said carriage being movably connected at said pivot points to said back axle of said roller skate with said back member oriented generally parallel to said axle, located further from said toe portion of said skate than said axle, said carriage riding on said skate above a skating surface, wherein rotation of said carriage in a first direction about said pivot points urges said back member towards said skating surface, and rotation of said carriage in a second direction about said pivot points urges said back member away from said skating surface;
- (b) a brake pad operatively connected to said back member so as to move towards and away from said skating surface in concert with said back member;
- (c) an actuator operatively connected to said carriage, said actuator urging said carriage to rotate in said first direction so that said brake pad is urged toward said skating surface when said actuator is engaged and;
- (d) a return mechanism operatively connected to said carriage, said return mechanism urging said carriage to rotate in said second direction so that said brake pad is urged away from said skating surface when said actuator is not engaged.
- 2. A roller skate brake system, comprising:
- a carriage comprising a carriage body and a braking surface operably attached to said carriage body, wherein said carriage body includes a pair of pivot points, and said carriage body is attached to a back axle of a roller skate at said pivot points so that said carriage may rotate about said back axle to move said braking surface toward or away from a skating surface; and
- an actuator operably connected to said carriage to rotate said carriage about said axle so as to engage said braking surface with said skating surface;
- wherein said roller skate is worn upon a foot, and an angle between a sole of said foot and said skating surface remains constant when said actuator rotates said carriage about said axle.
- 3. A system as in claim 2, wherein the actuator is hand-actuated.
- 4. A system as in claim 3, wherein actuator comprises a cable attached to the carriage body.
- 5. A system as in claim 2, further comprising a return mechanism operatively attached to the carriage to rotate the carriage about the back axle so as to disengage the braking surface from the skating surface.
- 6. A system as in claim 5, wherein the return mechanism comprises at resilient member extending between the carriage body and the roller skate.
- 7. A system as in claim 6, wherein the resilient is member comprises a spring.
- 8. A roller skate comprising:
- a frame having a front end and a back end and at least a back wheel attached to said frame near said back end by an axle;
- a carriage assembly comprising a carriage body and a braking surface, said carriage body including a pair of pivot points, wherein said carriage body is attached to said axle at said pivot points so that said carriage assembly may rotate about said axle to move said braking surface toward or away from a skating surface; and
- an actuator operably connected to said carriage assembly to rotate said carriage assembly about said axle so as to engage said braking surface with said skating surface.
- 9. A system as in claim 8, wherein the actuator is hand-actuated.
- 10. A system as in claim 9, wherein actuator comprises a cable attached to the carriage body.
- 11. A system as in claim 8, further comprising a return mechanism operatively attached to the carriage body to rotate the carriage body about the axle so as to disengage the braking surface from the skating surface.
- 12. A system as in claim 11, wherein the return mechanism comprises a resilient member extending between the carriage body and the frame.
- 13. A system as in claim 12, wherein the resilient member comprises a spring.
- 14. A method for slowing or stopping a roller skate, the method comprising:
- attaching a carriage assembly comprising a braking surface and a carriage body having a pair of pivot points to a back axle of the roller skate so that the carriage body may rotate about the back axle to move the braking surface toward or away from a skating surface; and
- rotating the carriage body about the back axle until the braking surface engages the skating surface.
- 15. A method as in claim 14, further comprising rotating the carriage body about the back axle until the braking surface is lifted from the skating surface.
- 16. A method as in claim 15, wherein the braking surface is lifted from the skating surface by a resilient member connected between the carriage body and roller skate.
- 17. A method as in claim 14, wherein the carriage body is rotated about the back axle to engage the braking surface with the skating surface by pulling a cable attached to the carriage body.
