DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a skate with improved steering capabilities.
Skates having aligned wheels are currently known, and they are ever more specifically used for speed skating and slalom.
The problem observed in these known types of skates, in which the wheels are pivoted at adapted supports which are rigidly associated with a supporting plate for the sole of an item of footwear, consists in the difficulty in achieving very tight turning radiuses.
Devices are known which allow to vary the distance of the axis of the wheels with respect to the ground, in order to adapt the skate to slalom or speed.
However, said devices are not practical to use and are expensive.
DE-G-9107661.7, for example, discloses such a skate with steering wheels.
SUMMARY OF THE INVENTION
The aim of the present invention is therefore to eliminate the problems described above in known types by providing a skate with aligned wheels by which it is possible to achieve a very tight turning radius.
Within the scope of the above aim, an important object is to provide a skate wherein turning can be achieved in a practical and easy manner for the athlete, requiring very little effort.
Another important object is to provide a skate which allows to achieve a turning radius which is as much as possible continuous, by means of devices having an extremely low cost.
Another important object is to provide a skate which is structurally simple and can be obtained with known machines and facilities.
Not least object is to provide an invention which associates with the preceding characteristics those of having low costs and of being at the same time reliable and safe in use.
This aim, the objects mentioned and others which will become apparent hereinafter are achieved by a skate with improved steering capabilities, comprising a support for the sole of an item of footwear and for at least three aligned wheels, characterized in that at least one of said wheels, which is arranged approximately in the median region, is arranged and rotates on a plane which is parallel to the plane of the remaining wheels.
BRIEF DESCRIPTION OF THE DRAWINGS
Further characteristics and advantages of the invention will become apparent from the detailed description of a particular embodiment, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
FIG. 1 is a rear view of a pair of skates during the execution of a left turn;
FIG. 2 is a view, similar to the preceding one, of the pair of skates during the execution of a right turn;
FIG. 3 is a schematic top view of the pair of skates, according to the invention, showing the position of the wheels;
FIG. 4 is a rear view of the pair of skates in the straight-line motion condition.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference to the above FIGURES, a skate structure composed of a right skate and of a left skate, generally designated by the reference numerals 1a and 1b, will be considered specifically.
Each of the skates is constituted by an item of footwear, designated by the reference numerals 2a and 2b. A plate, designated by the reference numerals 3a and 3b, is associated at the sole of the item of footwear. A support, designated by the reference numerals 4a and 4b, and constituted by a pair of parallel wings, protrudes from the plate. Four aligned wheels are pivoted, between the wings. The wheels are designated by the reference numerals 5a, 5b, 6a, 6b, 7a, 7b, 8a and 8b respectively starting from the tip of the item of footwear toward the heel thereof.
The number of aligned wheels can range from a minimum of three upward. In the present case, an embodiment with four aligned wheels is described.
At each skate 1a and 1b, the wheels 5a, 5b adjacent to the tip of the item of footwear and the wheels 8a, 8b adjacent to the heel thereof are arranged and rotate at a same first plane designated by the numerals 9a and 9b.
Said first plane is advantageously arranged parallel to the median plane which is longitudinal to the supports 4a and 4b, preferab
