Abstract
A roller skate with improved performance including a substantially U-shaped frame supporting in-line wheels. The skate comprises dampers that are adapted to absorb forces applied to the wheels and can be deactivated by tilting the frame.
Claims19
Roller skate with improved performance, comprising:
- a substantially U-shaped frame having wings supporting a plurality of aligned wheels therebetween;
- damping means adapted to absorb forces applied to the wheels, said damping means being deactivated by tilting said frame;
- and
- deactivation means that are adapted to deactivate said damping means, when said frame is tilted, said deactivation means comprising at least one protrusion that protrudes from at least one of the two inside lateral surfaces of said wings of said frame.

Roller skate with improved performance, comprising:
- a substantially U-shaped frame having wings supporting a plurality of aligned wheels therebetween;
- and
- damping means adapted to absorb forces applied to the wheels, said damping means being deactivated by tilting said frame;
- wherein the skate further comprises for each wheel of said plurality of wheels:
- a hub;
- a pivot coaxial with said hub, said pivot extending between said wings of said frame and having a pair of heads arranged respectively at outer sides of said wings for pivotally supporting said each wheel;
- a pair of shoulder rings coaxial with said pivot and arranged respectively at outer sides of said each wheel;
- and
- two spacers arranged coaxially about said pivot each respectively at one of said wings of said frame, each of said spacers being interposed respectively between a respective one of said heads of said pivot and a respective one of said shoulder rings, wherein said two spacers keep said each wheel central with respect to said frame, so that the median longitudinal plane of said frame coincides with the median plane of said each wheel;
- and
- wherein said damping means comprises pads arranged partially coaxially to said two spacers, on the opposite side with respect to the ground, said pads being at least partially arranged in adapted seats formed on said wings, and also protruding towards said facing two rings.

A roller skate with improved performance, comprising:
- a substantially U-shaped frame having substantially vertical wings;
- a plurality of aligned wheels rotatably supported between said wings of said frame;
- for each wheel of said plurality of wheels, a rotatable connection for rotatably connecting said each wheel between said wings of said frame;
- at least one elastic biasing element of said rotatable connection for permitting said each wheel to be displaced in a vertical direction with respect to said wings and for permitting said each wheel to be displaced also in a horizontal direction with respect to said wings;
- and
- at least one protrusion connected to at least one of said wings for engagement with at least one abutment connected in movement with said each wheel when said each wheel is displaced horizontally for blocking vertical displacement of said each wheel.
