Abstract
Abstract A skate brake system includes a rocker arm that pivots about the rear of a skate so as to bring a brake pad into contact with the skating surface when the rocker arm is activated. The rocker arm is mechanically activated so that the skater need not perform any special body movement so as to raise (or lower) the toe of the skate. Accordingly, the angle of the skate relative to the ground remains constant while the brake is applied.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
256 words
A roller skate brake system, comprising: (a) a rocker arm having a first end, a second end, and a pivot point located between said first and second ends, said rocker arm being rotatably connected at said pivot point to a roller skate, the rocker arm riding on said skate above a skating surface when the skate is being used to skate on said surface; a rotation of said rocker arm in a first direction about said pivot point urging said first end towards the skating surface, and a rotation of said rocker arm in a second direction about the pivot point urging said end away from the skating surface, (b) a brake pad operatively connected to said first end of the rocker arm so as to move towards and away from said skating surface in concert with said first end, and a hand-activated actuator operatively connected to said second end of the rocker arm, said actuator urging the rocker arm to rotate in said first direction so that the brake pad is urged towards said skating surface when the actuator is engaged and; (c) return means operatively connected to said rocker arm, said return means urging the rocker arm to rotate in said second direction about said pivot so that the brake pad is urged away from the skating surface when the actuator is not engaged, said brake system thereby using the skating surface for stopping said skate when the actuator is engaged and while the angle of the skate relative to the ground remains constant.
Claim 2
Dependent Claim
256 words
A roller skate brake system, comprising: (a) a rocker arm having a first end, a second end, and a pivot point located between said first and second ends, said rocker arm being rotatably connected at said pivot point to a roller skate, the rocker arm riding on said skate above a skating surface when the skate is being used to skate on said surface; a rotation of said rocker arm in a first direction about said pivot point urging said first end towards the skating surface, and a rotation of said rocker arm in a second direction about the pivot point urging said end away from the skating surface, (b) a brake pad operatively connected to said first end of the rocker arm so as to move towards and away from said skating surface in concert with said first end, and a hand-activated actuator operatively connected to said second end of the rocker arm, said actuator urging the rocker arm to rotate in said first direction so that the brake pad is urged towards said skating surface when the actuator is engaged and; (c) return means operatively connected to said rocker arm, said return means urging the rocker arm to rotate in said second direction about said pivot so that the brake pad is urged away from the skating surface when the actuator is not engaged, said brake system thereby using the skating surface for stopping said skate when the actuator is engaged and while the angle of the skate relative to the ground remains constant.
Claim 3
Dependent Claim
36 words
The system of claim 1, wherein said pivot point is connected to said skate near the rearmost wheel of the skate, being within about 4.0 inches of the axle of the rearmost wheel of said skate.
Claim 4
Dependent Claim
24 words
The system of claim 1, wherein said pivot point is connected to said skate at the axle of the rearmost wheel of said skate.
Claim 5
Dependent Claim
43 words
The system of claim 1, wherein said actuator comprises a cable operatively attached at one end thereof to said rocker arm, and said cable being operatively attached, at the other end thereof, to a hand operated controller for engaging and disengaging said actuator.
Claim 6
Dependent Claim
24 words
The system of claim 4, further comprising a belt worn by a skater, said belt including a holder for holding said hand operated controller.
Claim 7
Dependent Claim
20 words
The system of claim 5, wherein said holder includes means for releasably attaching said hand operated controller to said belt.
Claim 8
Dependent Claim
50 words
The system of claim 6, further comprising a retaining strap having a first end and a second end, the strap being connected at the first end thereof to said belt and, at the second end thereof, to said hand operated controller for retaining said controller when the controller is dropped.
Claim 9
Dependent Claim
11 words
The system of claim 7, wherein the retaining strap is elastic.
Claim 10
Dependent Claim
35 words
The system of claim 1, wherein said actuator comprises a wireless electromechanical device operatively connected to said rocker arm, and a hand operated electronic controller in wireless communication therewith for engaging and disengaging said actuator.
Claim 11
Dependent Claim
83 words
The system of claim 1, further comprising secondary braking means for stopping said skate int eh event of a failure of the actuator, said secondary braking means including an arresting bar operatively connected to the skate and disposed within the arcuate path of said rocker arm, said arresting bar restricting the arcuate range of motion of the rocker arm and arresting the rotation of the rocker arm at a limit of said range thereby locking said rocker arm in place at said limit.
Claim 12
Dependent Claim
59 words
The system of claim 1, wherein said brake pad has an embedded bolt affixed thereto with an end of said bolt extending outwards from said pad, and said rocker arm has a brake mounting plate attached thereto, said brake mounting plate having a hole adapted to receive said bolt for attaching the brake pad to said brake mounting plate.
Claim 13
Dependent Claim
48 words
The system of claim 11, wherein one of said brake pad and said brake mounting plate has a plurality of nipples and the other of said brake pad and brake mounting plate has a plurality of mating holes for seating said brake pad in said brake mounting plate.
Claim 14
Dependent Claim
112 words
The system of claim 1, further comprising: (a) a brake carriage having a first arm, a second arm and a back frame member connecting said first arm and said second arm, wherein said rocker arm is integrally formed as one of said first and second arms of said brake carriage, the other of said first and second arms having a pivot point opposite the pivot point of the rocker arm, said brake carriage being rotatably connected at said pivot points to a roller skate with the back frame member oriented towards the rear of the skate, and (b) a brake mounting piece connected to the brake carriage for holding said brake pad.
Claim 15
Dependent Claim
22 words
The system of claim 1, further comprising arresting means for stopping said skate in the event of a failure of the actuator.
