The present invention relates to a motorcycle boot.
It is known that one of the problems associated with the use of boots, in particular during motorcycle races, is that of overheating of the foot enclosed inside the boot, this representing a major problem for the user.
More generally, the problem of foot ventilation has been the subject of numerous studies and many solutions are known where holes are provided mainly in the tread of the boot, with special arrangements to prevent the entry of water in the event of rain.
Other solutions are also known, for example in the case of boots for in-line skates, where the shoe upper is provided with ventilation openings which are protected by air-permeable material (for example in the form of a fine mesh) so that, during use of the shoe, the air which enters through these ventilation openings or windows passes over the front part of the foot.
However, in the specific case of motorcycle boots, it is required to provide a substantial flow of cooling air and ensure that this flow passes over the entire bottom surface of the foot, without being limited to the front portion.
This result has not yet been achieved with the solutions proposed by the prior art and therefore constitutes the main technical problem and therefore the object of the present invention.
A more specific object of the present invention is to provide a motorcycle boot of the type suitable for the specific discipline known as motocross, provided with means for cooling the sole of the user's foot.
This object, together with others, is achieved by means of a motorcycle boot which has the characteristic features defined in Claim 1.
The main advantage achieved with the present invention is that of ensuring truly effective cooling and ventilation of the entire foot sole without negatively affecting the structure of the boot.
The features and advantages of the present invention will emerge more clearly from the description which follows of a preferred embodiment, provided with reference to the accompanying drawings in which:
With reference to the drawings, the boot to which the present invention relates has, by way of main components, a shell 20, a sole or tread 22, an inner bootie 24 and an upper 52.
Considering firstly the tread 22, this comprises a base 30, provided with the moulded patterns usually found in this type of boot, and a raised perimetral edge 32 which has at the front, namely at the toe end of the boot, three openings 34 which perform the function explained below when the tread is joined to the shell 20.
In particular, the perimetral edge is joined externally to the bottom edge portion of the shell, forming a reinforced strip.
If we now consider the shell 20, with reference to
The toe end of the shell 20 is provided with an opening 46 which is closed by means of a metal mesh 48 so that, when the tread is fixed to the shell so that its raised edge 32 surrounds and embraces the bottom edge of the shell 20, the three openings 34 are arranged so as to coincide with the opening 46, forming an air intake.
The shell 20 also has at the rear similar openings 50 which are protected by a mesh which acts as an outlet for the cooling air entering through the air intake described above.
If we now consider
As can be seen from
Since the two layers of fabric are perfectly permeable, the channels 56, when acted on by an air flow passing along their length, distribute the said air at right angles to their axis.
In the embodiment according to the present invention, the material forming the insole 54 is arranged with the tubular channels 56 parallel to the longitudinal axis of the boot.
From
The upper 52 houses internally what may be called an inner bootie 24 (
This is similar to a shaped stocking which matches the shape of the foot and is made of breathable fabric which allows the air to pass through freely.
The bootie 24 finally houses internally in a removable manner an insole made of the same material referred to above as Air Spring, the sole of the user's foot resting directly on said material.
From
The structure of the boot according to the present invention may be appreciated more fully from
Cooling and ventilation of the user's foot begins as soon as the rider mounts a motorcycle and starts a race.
The vehicle movement causes the entry of air through the air intake formed by the three front openings in the tread and the opening formed in the shell
The metal mesh prevents the entry of foreign bodies, such as grit.
The incoming air stream enters into the front ends of the tubular channels in the bottom insole of the upper, passing over the entire bottom surface of the upper.
At the same time this air stream is transferred at right angles to the overlying base of the inner bootie and via the breathable fabric of the bootie passes to the internal insole of the bootie, the tubular channels of which complete distribution of the air over practically all the bottom surface of the user's foot.
The air then passes out through the rear openings formed in the bootie, the opening formed in the upper and finally the screened openings formed at the rear in the shell.
In this way the problem of cooling and ventilation of the user's foot is solved, preventing, especially in sporting disciplines such as motocross, overheating of the foot, which occurs in particular during difficult and long races.
It is understood that conceptually and structurally equivalent variants are possible and may be envisaged, in particular in order to adapt the invention to boot designs which differ in terms of the conventional components.
In other words, it is possible to envisage adopting in other types of motocross boots the underlying principle of the present invention consisting in providing a front air intake, preferably screened by a protection system, a plurality of tubular channels which are aligned substantially with the longitudinal axis of the boot and able to distribute the air at right angles to their axis so that it reaches the sole of the user's foot.
