Abstract
Abstract The braking mechanism has two generally L-shaped levers, one on each side of the skate. Each lever has two arms, namely an upwardly projecting arm and a rearwardly projecting arm, pivotally connected to the chassis of the skate where the arms intersect, such that each upwardly projecting arm extends upwardly in general alignment with the skater's leg, and that each rearwardly projecting arm extends rearwardly from the chassis, the rearward distal ends having a brake pad secured beneath them. The upper distal ends may be connected to a pivotable boot cuff, but preferably instead have a generally C-shaped cup extending laterally between them, positionable behind the skater's calf. Rearward rotation of the skater's calf relative to the boot produces rearward movement of the upper distal ends, thereby moving the brake pad downwardly.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
228 words
A braking mechanism for an in-line skate, said skate having a boot and a wheel-carrying chassis secured beneath said boot, said braking mechanism comprising two generally L-shaped levers, configured for positioning one on each side of the skate, each lever having two arms, comprising an upwardly projecting arm and a rearwardly projecting arm, the area of each said lever where said arms of said lever intersect being configured for pivotal connection to said chassis at one of corresponding pivotal connections on each side of the chassis, such that when so connected at one of said pivotal connections, each said upwardly projecting arm extends upwardly from said pivotal connection towards the rear of the calf of a skater wearing said skate, to an upper distal end, and such that each said rearwardly projecting arm extends rearwardly from said wheel chassis to a rearward distal end, said rearward distal ends being joined and having a brake pad secured beneath them, said upper distal ends having a braking pressure receiving means mounted on or extending laterally between them, configured for positioning behind the skater's calf, whereby rearward rotation of the skater's calf relative to the boot, when said braking mechanism is installed, produces rearward movement of said upper distal ends, thereby moving said brake pad downwardly by virtue of rotation of said levers about said pivotal connections, to engage the ground.
Claim 2
Dependent Claim
228 words
A braking mechanism for an in-line skate, said skate having a boot and a wheel-carrying chassis secured beneath said boot, said braking mechanism comprising two generally L-shaped levers, configured for positioning one on each side of the skate, each lever having two arms, comprising an upwardly projecting arm and a rearwardly projecting arm, the area of each said lever where said arms of said lever intersect being configured for pivotal connection to said chassis at one of corresponding pivotal connections on each side of the chassis, such that when so connected at one of said pivotal connections, each said upwardly projecting arm extends upwardly from said pivotal connection towards the rear of the calf of a skater wearing said skate, to an upper distal end, and such that each said rearwardly projecting arm extends rearwardly from said wheel chassis to a rearward distal end, said rearward distal ends being joined and having a brake pad secured beneath them, said upper distal ends having a braking pressure receiving means mounted on or extending laterally between them, configured for positioning behind the skater's calf, whereby rearward rotation of the skater's calf relative to the boot, when said braking mechanism is installed, produces rearward movement of said upper distal ends, thereby moving said brake pad downwardly by virtue of rotation of said levers about said pivotal connections, to engage the ground.
Claim 3
Dependent Claim
33 words
A braking mechanism as recited in claim 1, configured such that each said pivotal connection may be connected to said chassis co-axially with a second wheel forward from the rear of the skate.
Claim 4
Dependent Claim
43 words
A braking mechanism as recited in claim 2, such that the distance from each said pivotal connection to said braking pressure receiving means is at least about two times the distance from each said pivotal connection to the center of said brake pad.
Claim 5
Dependent Claim
33 words
A braking mechanism as recited in claim 1, configured such that each said pivotal connection may be connected to said chassis co-axially with a first wheel forward from the rear of the skate.
Claim 6
Dependent Claim
43 words
A braking mechanism as recited in claim 4, such that the distance from each said pivotal connection to said braking pressure receiving means is at least about three times the distance from each said pivotal connection to the center of said brake pad.
Claim 7
Dependent Claim
61 words
A braking mechanism as recited in claim 1, configured such that each said pivotal connection is at a point not co-axial with one of the wheels, such that the distance from said each pivotal connection to said braking pressure receiving means is at least about two times the distance from each said pivotal connection to the center of said brake pad.
Claim 8
Dependent Claim
24 words
A braking mechanism as recited in claim 1, where said brake pad is adjustable upwardly or downwardly with respect to said rearwardly projecting arm.
Claim 9
Dependent Claim
44 words
A braking mechanism as recited in claim 1, where said upwardly extending arms are not integral with said rearwardly extending arms, but rather said arms are connected to each other, said connection being adjustable such that the angle between said arms may be varied.
Claim 10
Dependent Claim

A braking mechanism as recited in claim 1, where said upper distal ends are securable around the skater's calf by straps attached to said mechanism in the area of said upper distal ends.
Claim 11
Dependent Claim
54 words
A braking mechanism as recited in claim 1, further comprising a spring mounted between at least one of said levers and said skate to bias said brake pad away from the ground, whereby said brake pad is lifted away from the ground when said braking pressure is removed from said braking pressure receiving means.
