## Abstract

A skate with aligned wheels having a single plate provided with cantilever pivots for supporting the wheels. The pivots have a quick-release device for easily and rapidly removing and replacing the wheels.

## Claims

### Claim 1

A skate with aligned wheels, comprising:
a single wheel supporting plate;
a plurality of cantilever pivots connected to said supporting plate;
a plurality of wheels rotatably supported by said cantilever pivots;
said single supporting plate comprising a first section and a second section, said first section and said second section being substantially mutually parallel, said single supporting plate furthermore comprising a transverse section disposed in a vertical plane, interconnected between said first section and said second section, a first pair of said pivots being connected to said first section at a first side of said supporting plate, and a second pair of said pivots being connected to said second section at a second side of said supporting plate which is opposite to said first side thereof.

### Claim 2 (depends on 1)

The skate according to claim 1, wherein said cantilever pivots comprise quick-release devices for fastening said wheels.

### Claim 3

A skate with aligned wheels, comprising:
a single wheel supporting plate;
a plurality of cantilever pivots connected to said supporting plate;
a plurality of wheels rotatably supported by said cantilever pivots;
said single supporting plate comprising a first section and a second section, said first section and said second section being substantially mutually parallel, said single supporting plate furthermore comprising a first transverse section disposed in a vertical plane, interconnected between said first section and said second section, at least one first pivot of said pivots being connected to said first section at a first side of said supporting plate, and at least one second pivot of said pivots being connected to said second section at a second side of said supporting plate which is opposite to said first side thereof.

### Claim 4 (depends on 3)

The skate according to claim 3, wherein said cantilever pivots comprise quick-release devices for fastening said wheels.

### Claim 5 (depends on 3)

The skate according to claim 3, further comprising:
a third section and a fourth section both of which are substantially parallel to said first and second sections;
a second transverse section interconnected between said first section and said third section;
a third transverse section interconnected between said second section and said fourth section;
at least one third pivot of said pivots connected to said third section at said second side of said supporting plate; and
at least one fourth pivot of said pivots connected to said fourth section at said first side of said supporting plate.
