Abstract
Roller skates which utilize a single row of narrow wheels to support each skate include housings in a blade-like support for the skate wheels. A friction plate or bar is disposed along the side of the support and is dragged along the skating surface to stop movement of the skate. A plasticly deformable pivot is mounted at each end of the blade-like support to permit spinning movement thereon.
Claims5
A roller skate comprising:
- A skate wheel support having an upper portion including laterally extending flange portions adapted to be secured to the bottom of a shoe,
- said support having a downwardly extending wheel supporting portion,
- the lower portion of said wheel supporting portion having a plurality of cowl portions each defined by space-separated outwardly extending and downwardly depending opposite wall portions spaced apart from each other at the bottom of said wheel supporting portion and extending in longitudinal alignment with each other so as to define a plurality of wheel housings, each of which is open at the bottom of said wheel supporting portion of said support,
- a plurality of wheels extending in a row along the lower portion of said support with each wheel supported in bearing within each of said cowl portions of said support by the opposite walls thereof for supporting and providing wheeled movement of said skate across a surface, and
- a braking member secured to and supported by the sidewall of said support and having an outer surface of friction producing material which braking member is shaped and positioned to permit said outer surface to be engaged against the surface on which the skate is used to the exclusion of all other portions of said skate for slowing down and stopping movement of the skater along such skating surface.
