Description:
Motorcycle boot

DESCRIPTION

The present invention refers to a motorcycle boot of the type comprising an upper and a plurality of fastening devices configured so as to urge closed a first and a second strip of the upper. The plurality of fastening devices comprise at least one first fastening device which includes a rigid or semi-rigid support element, fixed to the first strip, and an engagement element fixed to the second strip.

In the field of motorcycle boots there is a need to ensure high protection for the ankle while maintaining partial mobility for the user.

For this purpose, motorcycle boots are known which are provided with devices capable of limiting the rotation about the axis of the malleolus, and simultaneously preventing twisting movements of the foot. For example, a boot provided with a system for limiting over-rotation in the front-rear direction is described in US 2011/067271.

Typically, these devices include the presence of a rigid shell formed by two portions, one integral with the upper part of the foot of the boot and the other with the cuff of the same.

However, the presence of such devices makes the fit of the boot particularly difficult, and in general, the comfort thereof.

On the contrary, it would be desirable to make a motorcycle boot available which can be easily worn and which guarantees good comfort during use.

The problem underlying the present invention is that of providing a motorcycle boot conceived to satisfy the requirements mentioned above with reference to the known prior art.

Within the scope of this problem, an object of the invention is to provide a motorcycle boot which allows adequate protection to the user while practising sports.

It is also an object of the present invention to provide a motorcycle boot in which the flexion movements about the axis of the malleolus are adequately limited.

A further object of the invention is to provide a motorcycle boot which can be easily worn and which guarantees a high level of comfort.

This problem is solved by the present invention with a sports shoe obtained according to claim 1.

It will be appreciated that the boot of the present invention comprises an upper and at least one fastening device configured so as to urge closed a first and a second strip of the upper.

The fastening device includes a support element, fixed to the first strip of the upper, and an engagement element fixed to the second strip.

Fixed at the support element of the first fastening element and of the upper, or vice versa, there are also an abutment member and retention means for the same abutment member.

The retention means are configured so as to retain the abutment member, allowing the limited sliding thereof along a sliding direction, so as to limit the oscillation about the bimalleolar axis between a foot portion and a cuff portion of the upper. It is thereby possible to exploit the boot fastening device to appropriately contain the movements of the user's foot.

The presence of the retention means or of the abutment member on the support element of the fastening device also allows to obtain this feature without limiting the wearability of the boot, which can be easily worn. According to another aspect of the invention, the retention means and the abutment member are located at a front area of the boot, providing adequate protection in a zone where the traditional movement limitation systems could make it difficult to wear the boot.

According to yet another aspect, there is a second fastening device which comprises a respective support element, said support element being fixed at the cuff portion.

In some embodiments, the retention means are fixed at the support element of the first fastening element, the abutment member being preferably formed in a tongue-like manner and extending from the cuff portion at an area located above the support element of the second fastening device.

These features allow to retain the abutment member once the engagement devices are closed, providing even further stability and protection to the boot.

In some embodiments, the support element of the second fastening device is configured so as to enclose the abutment member when the second fastening device is closed, further contributing to the protection.

Preferably also the second fastening device can provide a function of limiting the flexion about the bimalleolar axis, and for this purpose, the abutment member can comprise a further abutment surface configured so as to abut the support element of the second fastening device along the relative sliding direction.

On the basis of another aspect, the invention also refers to a motorcycle boot comprising an upper and a plurality of fastening devices configured so as to urge closed a first and a second strip of the upper, in which the upper includes a foot portion and a cuff portion capable of mutual oscillation about a bimalleolar axis. The boot comprises a consumable contact insert detachably connected to a protection shell of the cuff portion so as to be able to allow the replacement thereof.

In some embodiments, the boot comprises suitable connection means for the contact insert. In one of the preferred embodiments thereof, the connection means comprise a recess, preferably formed in the protection shell, and an engaging element, protruding from the recess and adapted to retain the insert between the engaging element and a portion of the shell.

On the basis of yet another aspect, the invention also refers to a motorcycle boot comprising an upper and a plurality of fastening devices configured so as to urge closed a first and a second strip of the upper, in which the upper includes a foot portion and a cuff portion capable of mutual oscillation about a bimalleolar axis and further comprising a reinforcement bar hinged at the bimalleolar axis and another hinging axis defined at the cuff portion in a zone vertically above the bimalleolar axis.

In some embodiments the bar is hinged in the hinging axis on a sliding pad in a relative guide which allow a limited translation.

In preferred embodiments, the bar can comprise means for limiting oscillation, preferably formed with an abutment element which abuts respective surfaces during the rotation of the bar itself. Further preferred features of the invention are defined in the dependent claims.

The features and advantages of the invention will become clearer from the detailed description of a preferred, but not exclusive, embodiment illustrated, by way of non limiting example, with reference to the appended drawings in which:

- figures 1 and 2 are a front view and a respective detail of a motorcycle boot obtained in accordance with the present invention, with respective fastening devices open;

- figure 3 is a partial outer side view of the motorcycle boot of figure 1, with the fastening devices closed;

- figure 5 is a perspective view of a protection shell of a cuff portion of the boot and of a related consumable contact insert, details of the boot of figure 1;

- figure 6 is a rear view of the motorcycle boot of the present invention, with the fastening devices open; - figures 7A and 7B are partial side views, respectively outer and inner, of the boot of the present invention from which the protection shell of the cuff portion has been removed in order to illustrate some components which are not normally visible.

With reference to figure 1, a motorcycle boot is indicated as a whole with the reference number 100.

The motorcycle boot 100 of the present invention comprising an upper 4 and a plurality of fastening devices configured so as to urge closed a first and a second strip 101, 102 of the upper 4. In the embodiment illustrated in the figure there are three distinct fastening devices respectively indicated with the reference numbers 1, 2, 6, the features of which will be illustrated in greater detail below.

The upper 4 includes a foot portion 41 and a cuff portion 42 capable of mutual oscillation about a bimalleolar axis X which extends In some preferred embodiments, the boot 100 comprises respective protection shells

51, 52 to reinforce and protect the foot portion 41 and the cuff portion 52, respectively. Preferably the shells 51, 52 are made of rigid or semi-rigid material, in relation to the material of the upper 4. By way of example, the shells 51, 52 can be made of plastic materials, such as PU or nylon. As illustrated in figures 3 and 4, the shells 51 and 52 can be articulated, for example by means of a pin 53, about an axis substantially coincident with the bimalleolar axis X of the user's foot, allowing forward and backward flexion movements about this axis, but not the twisting of the foot.

On the basis of still another aspect of the invention, illustrated in an exemplary embodiment thereof in figure 5, the boot 100 can comprise a consumable contact insert 7 arranged on the inner side of the boot 100 and preferably fixed to the protection shell 52 of the cuff portion 42. The contact insert 7 is for example made of rubber and is configured so as to protrude laterally from the surface of the upper 4 and/or from that of the shell 52 such that these do not come into direct contact with other components at the inner side of the boot.

Advantageously, the contact insert 7 can be replaceable, and for this purpose, the boot 100 comprises suitable connection means. In one of the preferred embodiments thereof, the connection means comprise a recess 53, preferably formed in the protection shell

52, and an engaging element 55, protruding from the recess 53 and adapted to retain the insert between the engaging element 55 and a portion of the shell 52.

Preferably the insert 7 comprises protrusions 70 which, when housed in the recess 53, protrude from the shell 52 through through-openings 54.

In some embodiments, the insert 7 can comprise a first and a second portion 71, 72, from which relative protrusions 70 protrude. The two portions can be joined by means of a bridge 73 which can extend between two engaging elements 55, once the insert 7 is housed in the recess 53. It is thereby possible to obtain a stable positioning of the insert 7 while allowing a simple replacement thereof once worn out. With reference now again to figure 1, the first fastening device 1 comprises a support element 11, fixed to the first strip 101 of the upper 4, and an engagement element 12 fixed to the second strip 102.

Preferably, the support element 11 comprises a hook 11 A, capable of engaging a lever 12A of the engagement element 12. However, it is clear that different solutions can be provided, such as a belt system, for urging the two strips 101 and 102 closed.

In general, the engagement devices can be arranged in a closed condition, illustrated for example in figure 3, or open, as illustrated in figures 1 and 2.

According to another aspect of the invention, a second fastening device 2 can be present which comprises a respective support element 21. In preferred embodiments, the support element 11 of the first engagement device 1 is arranged at the foot portion 41 and the support element 21 is fixed at the cuff portion 42.

Preferably, the support element 11 of the first fastening device 1 extends from the protection shell 51 of the foot portion 41 while the support element 21 of the second fastening device 2 extends from the protection shell 52 of the cuff portion 42. Preferably, a third engagement device 6 is present, located on the cuff portion 42 in a vertically higher position with respect to the engagement devices.

With reference to figures 1 and 2, the boot 100 of the present invention further comprises an abutment member 3 and respective retention means 10 configured so as to retain the abutment member 3, allowing limited sliding of said member along a sliding direction S,

Preferably, the abutment member 3 is of elongate form and is for example formed in a tongue-like manner. In this case, the abutment member extends on a substantially vertical plane and passes through a toe-heel direction of the boot 100. Advantageously, this direction is parallel to the sliding direction S which can therefore also lie within a substantially vertical plane passing through the toe-heel direction of the boot 100.

In some embodiments, the retention means 10 and the abutment member 3 are located at the front area of the boot 100, substantially at the ankle joint area. More generally, the retention means 10 and the abutment member 3 can be fixed one at the support element 11 of the first fastening element 1 and the other at the upper 4. It is understood that this location includes both the embodiment in which the abutment member 3 is fixed to the upper 4 and the retention means 10 to the support element 11, and the opposite embodiment. Furthermore, it will be understood that in the description of the present embodiment reference is made to the engagement device 11 fixed to the foot portion 41 but the same concepts may also be extended to the other engagement device. The solution described is in any case to be considered preferred since it is capable of rationalizing the overall dimensions of the components. In preferred embodiments, therefore, the abutment member 3 is fixed at the cuff portion 42 and the support element 11 is fixed at the foot portion 41, it being understood that, as mentioned above, the opposite solution may also be provided.

In preferred embodiments, in order to obtain the sliding along the direction S as previously mentioned, the retention means 10 can comprise a through-opening, preferably defined in the support element 11, inside which the abutment member 3 slides. It will be appreciated that the use of a through-opening allows the abutment member 3 to be made integral with the support element 11, allowing the first to be moved together with the second when it is necessary to widen the two strips of the upper to insert the foot into the boot 100. The abutment member 3 can in turn preferably have respective abutment surfaces 30A, 30B, for example defined by a recessed portion 30 of the abutment member 3, configured so as to abut respective ends of the aforementioned through-opening or more generally other surfaces of the retention means. The abutment surfaces 30A and 30B are preferably located on opposite sides of the retention means with respect to the sliding direction S.

In this manner, travel limit stops can be defined for the abutment member 3 along the sliding direction S which allows to limit the possibility of translation along this direction. It will therefore be appreciated that the respective location of the abutment member 3 and retention means 10 allow to limit the flexion about the axis X of the cuff portion 42 with respect to the foot portion 41.

In preferred embodiments, the support element 11 and/or the retention means are made of rigid or semi-rigid material so as to increase the stability of the foot in the travel limit stop positions. Also in this case, the support element 11 and/or the retention means can be made of plastic materials such as PU or nylon.

However, it will be appreciated that different configurations of the abutment member 3 and of the retention means can also be provided, as long as they are capable of limiting the oscillation about the bimalleolar axis X of the foot portion 41 with respect to the cuff portion 42.

In some embodiments, the second fastening device 2 also interacts with the abutment member 3.

For this purpose, the abutment member can extend from the cuff portion 42 at a zone located above, along a vertical direction of the boot 100, to the support element 21 of the second fastening device 2.

The support element 21 of the second fastening device 2 can also be configured so as to enclose the abutment member 3 when the second fastening device 2 is closed, in turn retaining the abutment member 3.

In some embodiments, the abutment member 3 can also comprise further abutment surfaces 30C, 30D configured so as to abut said support element 21 of the second fastening device 2 along said sliding direction S, in a manner similar to what occurs for the first fastening device 1.

Preferably, in this case the abutment member 3 simply rests on an outer surface of the support element 21, which can therefore be removed from the upper independently of the abutment member 3, again to the benefit of the ease of fitting and construction of the boot. In this case, therefore, the abutment surfaces 30C, 30D will abut a respective free edge of the support element 21. According to a further aspect of the invention, illustrated by way of example in figure 6, the boot further comprises abutment means 6 adapted to limit a rear flexion movement about the bimalleolar axis X between the cuff portion 42 and the protection shell 52 of the cuff portion 42 itself.

Preferably, the abutment means 6 are formed by two coupled surfaces, formed respectively on the cuff shell 52 and on a protection portion of the calf 53, which abut each other when the cuff is flexed backwards.

With reference now to figures 7A and 7B, on the basis of yet another aspect of the invention, the boot 100 can comprise a reinforcement bar 8 hinged at the bimalleolar axis X, at one of the first ends thereof, and at another hinging axis X' defined at the cuff portion 42 in an area vertically above the axis X at an opposite end thereof.

Preferably, a respective reinforcement bar 8 is present at both the inner side and the outer side of the boot 100.

In some embodiments, the bar 8 is hinged in the hinging axis X' on a sliding pad in a relative guide, not shown in the figure, which allow a limited translation along a translation direction T of the hinging axis X'.

In this manner, the reinforcing function provided by the bar 8 will in any case allow a certain functional mobility at the ankle.

As schematically illustrated in the figure, in preferred embodiments, the bar 8 comprises means for limiting oscillation, preferably formed as an abutment element 80 which abuts respective surfaces 8A, 8B during the rotation of the bar 8.

Preferably, the abutment element 80 is formed by a radial extension, with respect to the axis X, of the bar 8. The surfaces 8A and 8B can instead be defined at a cavity defined in the shell 51 and inside which the abutment element 80 moves. It will therefore be appreciated that thanks to the presence of the means for limiting the oscillation of the bar 8, the over-flexion movements of the ankle are prevented at another position. The combined presence of the abutment member 3 and of the means for limiting the oscillation of the bar 8 advantageously allows to significantly limit the risk of both front and rear over-flexion of the ankle, guaranteeing maximum protection for the user.

The invention thus achieves the proposed objects, achieving numerous advantages with respect to the known solutions.

In particular, the boot according to the present invention allows to prevent hyper- extension movements of the ankle, of the instep and of the rear tendon during the forward and/or backward flexion of the leg, conferring greater safety to the rider.
