Definitions
- the present invention relates to a skate with aligne wheels.
- a first type of conventional skate with aligned wheel has a support for an item of footwear from which a pair o longitudinal wings protrudes; a plurality of aligned whee l is freely pivoted transversely between the wings.
- This first conventional skate has a few inconveniences: the wheels are rigidly pivoted to the pair of wings and this causes a direct transmission to the item of footwear of all the stresses due to ground unevennesses encountered durin sports practice, with the consequent discomfort for th user.
- a sports implement which is predominantly used by skiers for summer training on roads, and is composed of a support for an item of footwear from which a frame protrudes centrally downward; the ends of two pairs of wheel supporting trucks are independently pivoted to the frame, and the head of a screw with a threaded stem is connected to the support in the interspace between two adjacent wheels.
- a complementarily threaded nut is associated with the stem and abuts on the ground-facing surface of a connecting element which is arranged transversely to each pair of trucks; a cylindrical helical compression spring is arranged coaxially to the stem.
- One aim of the present invention is to eliminate the problems described above in conventional skates by providing a skate which allows to protect the legs of the user against the stresses which can be transmitted thereto as a consequence of travel over rough or uneven ground.
- an object of the invention is to provide a skate which allows to protect the legs of the user against the stresses which can be transmitted thereto as a consequence of travel over uneven or rough ground without forcing the user to intervene directly in order to achieve these characteristics but allowing said user at the same time to adapt them to his own specific requirements, such as his weight and level of skill in the sport, or to the type of ground surface.
- a further object is to provide a skate which is simple, easy to industrialize, reliable and safe in use and has low manufacturing costs.
- a skate with aligned wheels comprising a support for an item of footwear from which a frame protrudes downward, first ends of at least two pairs of wheel supporting trucks being independently pivoted to said frame, and comprising a connecting element, said connecting element protruding below said support, said connecting element being adapted to connect said first ends of said at least two wheel supporting trucks, characterized in that means for adjusting the oscillation of said at least two trucks with respect to said support are associated with said connecting element.
