Abstract
In a braking device for roller skates (1), especially in-line (i.e. "single-track") roller skates, with a brake block (5) which is removably secured to the frame (2) or the boot (1), the brake block is mounted on the frame (2) or boot so as to pivot against the force of a spring (6), thus permitting gentle application of the brake. At the same time, maximum braking is possible if needed, due to a projecting part of the brake block (5) which is supported in a guide and can be applied to or moved against a roller, without risk of putting the skater off balance during braking.
Claims14
A braking device for a roller skate comprising a boot and a frame, said frame mounting rollers for rotation about respective parallel roller axes, said braking device comprising:
- an actuation block including a bottom contact surface, said actuation block detachably mounted to one of said frame and said boot, for pivotal movement about a pivot axis from an inoperative position to an operative position against a force of a spring located between said actuation block and one of said frame and said boot, acting to return said actuation block to the inoperative position, said pivot axis being generally parallel to the roller axes;
- a braking member associated with said actuation block and arranged to frictionally contact at least one of said rollers when said actuation block is pivoted to its operative braking position;
- and
- a guideway provided in at least one of said frame and said actuation block, cooperating with a shaft extending through said frame and parallel to said pivot axis to guide and support said actuation block and said braking member during pivotal movement of said actuation block and said braking member relative to said frame and in the operative braking position thereof.
A braking device for a roller skate comprising a boot and a frame, said frame mounting rollers for rotation about respective parallel roller axes, said braking device comprising:
- an actuation block including a bottom contact surface, said actuation block detachably mounted to one of said frame and said boot, for pivotal movement about a pivot axis from an inoperative position to an operative position against a force of a spring located between said actuation block and one of said frame and said boot acting to return said actuation block to the inoperative position, said pivot axis being generally parallel to the roller axes:
- a braking roller associated with said actuation block and arranged to frictionally contact at least one of said rollers when said actuation block is pivoted to its operative braking position;
- and
- a guideway provided in at least one of said frame and said actuation block, to guide and support said actuation block and said braking roller during pivotal movement thereof relative to said frame and in the operative braking position thereof, and wherein said braking roller has as shaft which is slidingly guided in said guideway.
A braking device for a roller skate having a plurality of rollers mounted on respective axles in a frame, said braking device comprising a brake holder pivotally mounted on the axle of a rearmost roller, said brake holder supporting a ground engaging actuation block and a roller engaging braking member;
- a spring located between said frame and said holder biasing said braking member to an inoperative position;
- intersecting slots provided in said frame and said holder and a shaft received in said intersecting slots and extending parallel to said pivot axis through said frame, said braking member and said brake holder, for guiding said holder and said braking member during pivotal movement of said holder about said pivot axis.
