Abstract
A skate housing assembly for high speed in-line roller skates. There is a frame with a top surface attached to a sole of a skate boot and two descending side skirts having multiple linear transverse bores. A pocket located on the inside surface of each descending skirt surrounding a bore receives a flange from a bearing insert mounted within a skate wheel. A shaft axially mounted through the skirt bores and bearing insert aligns the wheel on the skate housing.

A skate housing assembly for a high speed in-line roller skate comprising
- a longitudinal frame having an intermittent top surface adapted to be attached to a sole of a shoe,
- identical frame skirts descending from opposite side edges of the top surface,
- multiple linear transverse bores located in a bottom portion of the descending frame skirts,
- an inside surface of the descending frame skirts surrounding each transverse bore configured to form a pocket,
- three to five wheels mounted in a row, each wheel supported on a hub containing a central axial bore, the central axial bore aligned within the longitudinal frame with the transverse bore of opposed frame skirts on opposite sides of each wheel,
- a pair of bearing inserts mounted within the central axial bore through the wheel hub, the bearing inserts having a flange at a first end for seating in the pocket and a shaft element through the bores to retain the wheels within the frame.

A skate housing assembly for a high speed in-line roller skate having 3-5 wheels, the housing assembly comprising
- a top surface having multiple bores for receiving attachment devices for securing the skate housing to the sole of a shoe,
- a pair of downwardly descending skirts from respective side edges of the top surface,
- multiple transverse bores along a lower portion of each skirt,
- a pocket formed around each bore on an inner surface of each skirt,
- each wheel having a hub for receipt of a pair of bearing inserts from opposite sides of the wheel,
- a first end of each bearing insert having a flange for engagement within the skirt pocket,
- each bearing insert having an internal groove along a central bore for receipt of a bearing removal tool,
- a shaft element mounted through the transverse bore of the skirt, through the central bore of the pair of bearing inserts and through the transverse bore on the opposite skirt and means for retaining the shaft element in place to axially align the wheel with respect to opposed skirt transverse bores.
