In-line roller skate having easily replaceable bearings

Claim 2

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.

Claim 3

A skate housing assembly for a high speed in-line roller skate according to claim 1 wherein the shaft element is a bolt retaining the wheel in place on the skate housing frame.

Claim 4

A skate housing assembly for a high speed in-line roller skate according to claim 1 wherein each bearing insert has an axial bore for receiving the shaft element and a groove within an inside surface for receiving a bearing removal tool.

Claim 5

A skate housing assembly for a high speed in-line roller skate according to claim 1 wherein each wheel hub central axial bore receives a pair of bearing inserts abutting at a second end about half way through the wheel hub central axial bore and an inner edge of the bearing insert is stopped by a ridge located on an inner surface of the wheel hub.

Claim 6

A skate housing assembly for a high speed in-line roller skate according to claim 2 wherein the bolt is transversely mounted through the transverse bore of the descending frame skirt on a first side of the skate housing assembly, through the bearing inserts enclosed in the wheel central axial bore, and through an opposed transverse bore of the descending frame skirt on a second side of the skate housing assembly.

Claim 7

A skate housing assembly for a high speed in-line roller skate according to claim 5 wherein the bolt is received by a hex nut on the second side of the descending frame skirt of the skate housing assembly.

Claim 8

A skate housing assembly for a high speed in-line roller skate according to claim 3 wherein the bearing removal tool has a shaft with nipples located at a distal end from a head portion for engagement with the grooves on the inside surface of the bearing insert.

Claim 9

A skate housing assembly for a high speed in-line roller skate according to claim 1 wherein the wheel diameters may be 76 mm to 82 mm.

Claim 10

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.

Claim 11

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.
