Abstract
A roller skate device, including: at least one skate wheel. A cradle including a control wire. And a lever system coupled to the control wire, the lever system including at least one brake wheel that applies a braking force to the at least one skate wheel based on the motion of the cradle translated through the control wire.
Claims18
A roller skate device, comprising:
- at least one skate wheel;
- a rear shoe block comprising a control wire;
- a cradle comprising a locking mechanism;
- a lever system coupled to the control wire, the lever system comprising at least one brake wheel that applies a braking force to the at least one skate wheel based on the motion of the cradle translated through the control wire;
- wherein the control wire comprises a first end having a peg connectable to the locking mechanism and a second end comprising a hook, the peg connecting to the locking mechanism and pulling the control wire when the cradle moves in a first direction, and the peg disconnecting from the locking mechanism and releasing the control wire when the cradle moves in a second direction.

A roller skate device, comprising:
- at least one skate wheel;
- a cradle comprising a locking mechanism;
- a rear shoe block comprising a control wire comprising a first end having a peg connectable to the locking mechanism and a second end comprising a hook, the peg connecting to the locking mechanism and pulling the control wire when the cradle moves in a first direction, and the peg disconnecting from the locking mechanism and releasing the control wire when the cradle moves in a second direction;
- a lever system comprising:
- a lever comprising a knob connectable to the hook and which moves between a first position and a second position;
- a rotational wheel coupled to the lever that translates motion from the lever as it rotates about an axis;
- a slider coupled to, and receiving the translated motion from, the rotational wheel that moves between a retracted position when the lever is in the first position and an advanced position when the lever is in the second position;
- and
- at least one brake wheel connected to the slider that moves in an engaged position to engage the at least one skate wheel to provide a braking force when the slider is in the advanced position and that moves in a released position when the slider is in the retracted position.
