DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to an adjustment device for sports implements, particularly for a skate comprising a plurality of aligned wheels.
Skates which have mutually aligned wheels are currently known; their use is aimed, to an increasingly specific extent, to the sports practice of speed skating or slalom.
These two different specialties require the wheels of the skate to have different arrangements with respect to the support for the item of footwear: slalom in fact requires a configuration which allows to achieve a very tight radius of curvature, whereas speed skating requires a configuration which allows to achieve the straightest possible driving.
Skates are thus known which have aligned wheels wherein the variation of the position of said wheels is achieved by virtue of the interaction of the ends of the pivot of each wheel with a separate eccentric element.
The disadvantage which can be observed in these known types of device consists of the fact that the partial disassembly of the assembly constituted by the wheel and by the pivot is required in order to then be able to rotate the eccentric through 180.degree. in order to achieve a different arrangement of the axle of the wheel with respect to the support of the wheel or to the ground.
This all leads, therefore, to a scarce functionality and practicality of said known devices, which force the user to perform long interventions which require the use of special tools.
It is furthermore possible to achieve only two different positions which are due to the two positions which the eccentric element can assume.
SUMMARY OF THE INVENTION
The aim of the present invention is therefore to eliminate the disadvantages described above in known types by providing a skate with aligned wheels in which it is possible to rapidly and easily adjust the distance between the support for an item of footwear and the axle of one or more of the aligned wheels.
A further aim of the present invention is to provide a skate with aligned wheels wherein it is possible to rapidly and easily adjust the distance between the sole of an item of footwear and the axle of one or more of the aligned wheels.
Within the scope of this aim, an important object is to provide a device wherein the user can perform said adjustments without having to have particular tools available.
Another object is to provide a device which allows to achieve a continuous and not discrete adjustment.
Another important object is to provide a device which is structurally simple and wherein it is not necessary to disassemble the various components in order to achieve said adjustment.
Not least object is to provide a device which associates with the preceding characteristics that of being reliable and safe in use.
This aim, these objects and others which will become apparent hereinafter are achieved by an adjustment device for sports implements, particularly for a skate comprising a support for an item of footwear and at least two aligned wheels each having a shaft, characterized in that adjustment means are provided between said at least two aligned wheels and are suitable for simultaneously varying the interspace between said wheels and the distance between said support and the shaft of said at least two aligned wheels.
BRIEF DESCRIPTION OF THE DRAWINGS
Further characteristics and advantages of the invention will become apparent from the detailed description of a preferred but not exclusive embodiment, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
FIG. 1 is a partially sectional side view of a skate according to the invention with the wheels arranged in the condition of minimum extension with respect to the frame;
FIG. 2 is a partially sectional top view of the skate according to the line II--II of FIG. 1; FIG. 3 is a partial sectional view, taken along a longitudinal median sectional plane, of a skate according to a further aspect of the invention with the wheel arranged in the condition of minimum extension with respect to the frame
