Abstract
A roller skate comprising a foot-supporting plate having a normally-raised rear brake wheel, which brake wheel is activated by tilting the plate backwardly, the plate being supported at a low center of gravity between a pair of side wheels and having an extendable front wheel, which front wheel and brake wheel being adjustable to suit the individual skater in terms of skate stability and braking action.
Claims17
A roller skate comprising
- a foot supporting plate carrying means for engaging a human foot thereon,
- a front wheel carried by a yoke fixedly connected to said plate,
- said front wheel extending above said plate and being in front of said means for engaging,
- a pair of side wheels mounted on both sides of said plate and extending above said plate,
- means for suspending said plate on said side wheels for lateral tilting motion of said plate and said front wheel relative to said side wheels, and
- brake means comprising a rear brake wheel secured to the rear of said plate and activated by movement of a skater's foot,
- whereby said plate and front wheel can be tilted as a skater leans during turning while said front and side wheels remain on the ground.

A roller skate comprising
- a foot supporting plate carrying means for engaging a human foot thereon,
- pair of wheels mounted on both sides of said plate about a side wheel axis and extending above said plate, and
- a front wheel carried by a yoke fixedly connected to said plate,
- said front wheel extending above said plate and being in front of said means for engaging,
- means for adjusting the height of said front wheel relative to said plate to adjust the angle of said plate and foot in use,
- a brake wheel secured to the rear of said plate and activatable by pivoting of said plate about the side wheel axis, and
- means to adjust the position of said brake wheel to engage the ground in response to different amounts of pivoting,
- whereby the angle of the plate is adjustable to accomodate persons of different levels of skill at different speeds, and the brake position is adjustable in response to different plate angles and to the desired sensitivity of the user.
