Abstract
Abstract A roller skate toe brake includes a generally flat pedal inside the toe portion of shoes adaptable to in line roller skates. The pedal is hinged to the shoe and is movably connected to a brake pad located over one of the rollers. The pedal and brake pad are spring activated to keep the brake pad from touching the roller in the open position. When braking is desired, the skater activates the pedal which action closes the brake pad onto the roller and the skating surface to brake the roller skate. The roller skate toe brake is intended to improve the safety of roller skating and to facilitate hockey and figure skating maneuvers.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
357 words
A roller skate containing wheels having a brake comprising: a generally flat pedal movably located in said roller skate and operatively connected to actuator means, a brake lever located between two of said wheels, one of which is the brake wheel, of said roller skate, said brake lever connected to said pedal and actuator means having a first arm, a second arm and a base connecting said first arm and second arm, the first arm having a pivot point, the second arm having a pivot point opposite the pivot point of the first arm, said pivot points being elongated along an arc with the center at the axis of said brake wheel and located over the horizontal center line of said wheels, said brake lever being rotatably connected at said pivot points to said roller skate with said base oriented towards the skating surface of the roller skate when the roller skate is being used on said surface, a rotation of said brake lever when acted upon by said pedal and said actuator means, in a first direction about said pivot points urging said base towards said brake wheel and said skating surface, and a rotation of the brake lever in a second direction urging said base away from said brake wheel and said skating surface, a brake pad operatively connected to said brake lever so as to move towards and away from said brake wheel and said skating surface in concert with said brake lever, spring means operatively connected to said brake lever, said spring means urging said brake lever to rotate in said second direction so that the brake pad is urged away from said brake wheel and said skating surface and said pedal is urged into its disengaged position and; wherein said pivot points are connected to the support structure of said roller skate thereby using the momentum of said brake wheel to urge said brake pad into braking contact with said skating surface in front of said brake wheel for stopping said roller skate when said pedal is engaged and while the angle of the skate relative to said skating surface remains constant.
Claim 2
Dependent Claim
357 words
A roller skate containing wheels having a brake comprising: a generally flat pedal movably located in said roller skate and operatively connected to actuator means, a brake lever located between two of said wheels, one of which is the brake wheel, of said roller skate, said brake lever connected to said pedal and actuator means having a first arm, a second arm and a base connecting said first arm and second arm, the first arm having a pivot point, the second arm having a pivot point opposite the pivot point of the first arm, said pivot points being elongated along an arc with the center at the axis of said brake wheel and located over the horizontal center line of said wheels, said brake lever being rotatably connected at said pivot points to said roller skate with said base oriented towards the skating surface of the roller skate when the roller skate is being used on said surface, a rotation of said brake lever when acted upon by said pedal and said actuator means, in a first direction about said pivot points urging said base towards said brake wheel and said skating surface, and a rotation of the brake lever in a second direction urging said base away from said brake wheel and said skating surface, a brake pad operatively connected to said brake lever so as to move towards and away from said brake wheel and said skating surface in concert with said brake lever, spring means operatively connected to said brake lever, said spring means urging said brake lever to rotate in said second direction so that the brake pad is urged away from said brake wheel and said skating surface and said pedal is urged into its disengaged position and; wherein said pivot points are connected to the support structure of said roller skate thereby using the momentum of said brake wheel to urge said brake pad into braking contact with said skating surface in front of said brake wheel for stopping said roller skate when said pedal is engaged and while the angle of the skate relative to said skating surface remains constant.
Claim 3
Dependent Claim
30 words
The roller skate of claim 1, wherein said brake pad exerts braking contact with said brake wheel and said skating surface in combination and in front of said brake wheel.
Claim 4
Dependent Claim
30 words
The roller skate of claim 2, wherein more than one of said brake pad exert braking contact with more than one of said brake wheel and skating surface in combination.
Claim 5
Dependent Claim
36 words
The roller skate of claim 1, wherein said pedal is hinged to the sole of said roller skate, the sole containing a recess to accomodate the movement of the pedal when pressed down by the skater.
Claim 6
Dependent Claim
21 words
The roller skate of claim 1, wherein said pedal is hinged to the roller skate above the foot of the skater.
Claim 7
Dependent Claim
21 words
The roller skate of claim 1, wherein said pedal contains a padding on the side facing the foot of the skater.
Claim 8
Dependent Claim
14 words
The roller skate of claim 1, wherein said pedal has adjustable means for positioning.
Claim 9
Dependent Claim
14 words
The roller skate of claim 1, wherein said actuator means comprise a contact arm.
