The present invention relates to a motorcycling boot, in particular a motocross boot.
It is known that the lower limbs of motorcyclists are prone to injury, which may also be of a serious nature, in the event of accidental falls or impacts.
In order to reduce this risk as far as possible, during recent years special boots which have increased considerably the level of safety for users have been developed.
The safety offered by conventional leather boots has been greatly increased by introducing suitable protection means made of rigid or semi-rigid plastic.
Said protection means, which are mounted in the zones of the leg most exposed to injury, such as the instep, toes, shin, calf, may be directly injected onto the upper which forms part of the boot or may be applied by means of suitable gluing.
With use of these protection means not only is the motorcyclist's leg adequately protected against possible impacts or friction on the ground, but also unnatural movements of the lower limb as a result of the forces produced by an impact or accident are prevented.
In these boots which incorporate rigid and/or semi-rigid protection means it is known to provide soft portions in the region of the ankle joint so as to allow flexing of the foot.
In this way the foot is allowed a certain freedom of movement, while keeping it protected and supported, together with the ankle.
The abovementioned boots, although widely appreciated, are not without drawbacks.
In particular, the protection means arranged at the shin and calf, while they provide adequate protection, on the other hand make the boot rigid, limiting its comfort.
In fact, it has been possible to establish that, despite the soft portion provided in the ankle region, the rigid protection means on the shin and on the calf, since they are able to flex only by a small amount, also limit the backwards and forwards flexing movement of the boot leg-piece.
The top portion of the boot, in fact, may be regarded on the whole as being a single rigid body.
During these backwards or forwards flexing movements the leg-piece of the boot no longer fits the shape of the leg and it is possible that, in particular at the bottom ends, said protection means may exert a considerable pressure on the user's leg, causing discomfort, which is only partly relieved by the presence of suitable padding.
By way of a further consequence, whenever the leg-piece of the boot flexes forwards or backwards numerous folds form on the boot upper, at the instep or heel, and these may also be the cause of discomfort for the user.
Finally, said protection means do not allow the boot leg-piece to fit perfectly to calves and legs of different sizes.
Said drawback is partly offset by the provision of suitable closing devices which allow the upper and the associated protection means to adhere to the leg in a satisfactory manner.
It is evident, however, that in particular in the case of calves which are bigger than normal, the inability of the boot to fit to the rear profile of the leg creates a certain amount of discomfort.
The object of the present invention is therefore to overcome the drawbacks of the prior art.
In particular, a task of the present invention is to provide a motocross boot which provides adequate protection for the user's leg and foot, but at the same time allows greater flexing of the top portion of the leg-piece.
Moreover, a task of the present invention is to provide a motocross boot with an improved capacity to fit to legs and calves of different sizes.
The object and the abovementioned tasks are achieved by a motorcycling boot according to claim 1.
The characteristic features and further advantages of the invention will emerge from the description provided hereinbelow, of an example of embodiment, provided by way of a non-limiting example, with reference to the accompanying drawings in which.
The present invention relates to a motorcycling boot 10, in particular a motocross boot.
The description of the boot 10 and its individual components which will be provided below relates to a boot 10 used correctly. In particular, “front” will be used to indicate the part of the boot, or of the individual components, which is relatively closer to the toes of the foot, while “rear” will be used to indicate the part of the boot, or of its individual components, which is relatively closer to the heel. Similarly, “top” will be used to refer to the part of the boot, or of the individual components, which is relatively further from the ground, while “bottom” will be used to indicate the part of the boot, or of the individual components, which is relatively closer to the ground.
With reference to
A first protection means 20 is connected to said leg-piece 16 in the region of the shin, while a second protection means 30 is connected to said leg-piece 16 in the region of the calf.
Said first protection means 20 comprises an element 24 designed to slide inside guiding means 25 formed in said first protection 20, while said second protection means 30 comprises an element 34 designed to slide inside guiding means 35 formed in said second protection means. The movement of said elements 24, 34 allows variation, during use of the boot 10, of the configuration of the leg-piece 16.
The upper 14 is preferably made of leather or similar materials or synthetic fabrics and is formed by several parts which are generally joined together by means of stitching.
The upper 14 in some cases may be provided with soft plastic inserts which are directly injected onto the upper itself or are applied by means of stitching or thermoforming.
The first protection means 20 and the second protection means 30 are generally made of rigid and/or semi-rigid plastic. They are applied to the top portion of the leg-piece 16 by means of suitable stitches or by means of known heat-welding methods.
It is known that the shin-bone has an oblong form, which is wider at the top where it enters into and forms part of the knee joint, narrower in the central portion and slightly wider in the bottom part where it is joined to the ankle.
In the preferred embodiment, the element 24 of the first protection means 20 is positioned on the front portion of the leg-piece 16 at the central portion of the shin.
In addition to the element 24, preferably, the first protection means 20 also comprises a front plate 22 which is also positioned on the front portion of the leg-piece and which is shaped so as to be able to surround the top portion of the shin-bone.
As can be noted from
The thickness of the front plate 22 is not uniform: it is greater in the central portion and tapers gradually at the top and side ends.
Preferably, as shown in
In the preferred embodiment, the guiding means 25 are provided in the central portion of the front plate 22 where, as mentioned above, the thickness of the protection means is greater.
Said guiding means 25 consist of a pocket with a substantially rectangular shape.
As shown in
Said pocket 25 communicates with the external environment by means of an opening 26 which is positioned at the bottom end of the front plate 22 and is suitable for housing internally the top end of the element 24 and guiding it, as will be described in detail below, during the respective movement.
In the preferred embodiment, the element 24 has substantially the shape of an overturned T and covers part of the central portion of the shin.
As shown in
The head-piece 27 of the element 24 is positioned on the upper 14 in a manner substantially parallel to the plane on which the boot 10 rests.
It is mounted on a portion of the upper 14 provided with suitable padding 80. In this way the user does not perceive any discomfort due to the presence of said rigid element in contact with the corresponding shin.
The shank 28 of the element 24, as shown in the accompanying figures, has a non-uniform thickness along its length.
In particular, as shown in
The shank 28, in fact, in the zone between the portion 29 and head-piece 27 of the element 24 has a thickness which is greater than the thickness of the pocket 25. As a result, sliding of the element 24 inside the pocket 25 beyond a well-defined point is prevented.
In the preferred embodiment, the width of the shank 28 is slightly smaller than the width of the pocket 25.
In this way the shank 28 is able also to perform a slight rotation inside the pocket 25. There exists therefore, albeit to a limited degree, a further possibility of relative movement of plate 22 and element 24.
In the preferred embodiment, the element 34 of the second protection means 30 is positioned at the central portion and bottom portion of the calf muscle.
In addition to the element 34, the protection means 30 comprise preferably also a rear plate 32 which is positioned on the rear portion of the leg-piece 16 and which is shaped so as to be able to surround the top portion of the user's calf muscle.
As can be noted from
When the boot 10 is closed by the user, the shin plate 22 is advantageously arranged over the end portion of said rear plate 32. In this way it is ensured that there are no zones of the top end of the leg which are left unprotected, apart from the zones facing the motorcycle.
The thickness of the rear plate 32 is not uniform: it is greater in the central portion and tapers gradually at the top and side ends.
The rear plate 32, as can be noted in
In the preferred embodiment, the guiding means 35 are provided in the central portion of the front plate 32 where, as mentioned above, the thickness of the protection means is greater.
Said guiding means 35 consist of a pocket with a substantially rectangular shape.
The axis of symmetry of said pocket 35 substantially coincides with the longitudinal axis of symmetry S of the pocket 25 provided in the front plate 22.
Said pocket 35 communicates with the external environment by means of an opening 36 which is positioned at the bottom end of the plate 32 and is suitable for housing internally the top end of the element 34 and guiding it, as will be described in detail below, during the respective movement.
The element 34 is also mounted on the upper 14 at a portion provided with suitable padding 80.
In the preferred embodiment, the element 34 has substantially the shape of an overturned Y.
As shown in
In the preferred embodiment, the end of the head-piece 37 which is arranged along the outer side of the leg extends until it embraces almost completely the bottom portion of the calf.
In this way, when the boot 10 is closed by the user, the end 27 of the element 24 is advantageously arranged over said head-piece end.
The shank 38 of the element 34, as shown in the accompanying figures, has a non-uniform thickness along its length.
In particular, as shown in
The element 34 may slide inside the pocket 35 until the portion 39 comes into contact with the opening 36.
The shank 38 of the element 34, in fact, in the zone between the portion 39 and head-piece 37 of the element 34 has a thickness which is greater than the thickness of the pocket 35. As a result, sliding of the element 34 inside the pocket 35 beyond a well-defined point is prevented.
In the preferred embodiment, the width of the shank 38 is slightly smaller than the width of the pocket 35.
In this way the shank 38 is able to perform a slight rotation inside the pocket 35.
Operation of the protection means 20 and 30 will be described below with reference to
In detail, the rest configuration occurs when the user's leg does not exert any pressure, either forwards or backwards, on the leg-piece of the boot. In said configuration, it may be considered, with a more or less acceptable degree of accuracy, that the axis of the leg-piece is perpendicular to the resting plane of the ground 40.
The flexed configuration occurs when the user's leg exerts a pressure on the front portion of the boot leg-piece which, as a result of this pressure, flexes forwards.
The extended configuration occurs, instead, when the user's leg exerts a pressure on the rear portion of the boot leg-piece. In this case the leg-piece flexes backwards.
As soon as the user exerts a pressure on the front portion of the boot leg-piece, the leg-piece passes from the rest configuration into the flexed configuration.
In this configuration the front portion of the leg-piece 16 not only flexes forwards, but is also subject to a compression from the top downwards.
As shown in
In said flexed configuration, the rear portion of the leg-piece 16 also flexes forwards, but differently from that which occurs for the front portion of the leg-piece, is subject to a tensile force.
As shown in
The width and the thickness of the pockets 25 and 35 allow the elements 24 and 34 to be guided during their movements and prevent the possibility of any misalignment between the various components which form the first protection means 20 and the second protection means 30.
It should be noted, also, that the element 24 may slide inside the pocket 25 until the portion 29 comes into contact with the opening of the protection means. It is clear, therefore, that the introduction of said protection means, on the one hand, increases the flexibility and the comfort of the boot, but, on the other hand, does not affect the required rigidity. In the case where the front portion of the leg-piece is subject to high compressive forces, the protection means are configured to ensure optimum protection of the leg.
It should be noted, moreover, that, when the element 24 reaches the end of its travel movement inside the first protection means 20, the movement of the element 34 inside the second protection means 30 also stops.
As mentioned above, the extended configuration of the leg-piece occurs when the user exerts a pressure on the rear portion of the leg-piece.
In this configuration the rear portion of the leg-piece not only flexes backwards, but is also subject to a compression from the top downwards.
As shown in
In said extended configuration, the front portion of the leg-piece 16 also flexes backwards, but differently from that which occurs for the rear portion of the leg-piece, is subject to a tensile force.
As shown in
In a manner similar to that described in connection with the first protection means 20, the element 34 may also slide inside the pocket 35 until the portion 39 comes into contact with the opening of the pocket.
In reality, as shown in detail in
In this way it is evident how both the front portion and the rear portion of the leg-piece 16, in the different configurations, always remain in close contact with the user's leg ensuring a high degree of comfort for the latter, while maintaining the same degree of safety offered by the boot 10.
Owing to the possibility of the relative movements of the components of the protection means 20 and 30, the boot 10 is able to fit also to different calf types.
In the case of large-size calf, the possibility of the rear plate 32 to flex with respect to the element 34 ensures an improved wearability.
With reference to
Said fasteners have the function of tightening, relative to each other, the opposite flaps of the upper 14 so as to allow the boot 10 to adhere to the user's leg during use.
Each of said fasteners comprises: a toothed bar 62 and a lever 64 suitable for engaging with the toothed bar 62 in at least one position.
The lever 64, by means of the strap 66, is permanently connected to a first boot flap.
The surface of the strap 66 facing the upper 14 of the boot 10 (not shown in the accompanying figures) has a toothed profile which may be engaged with the rack provided inside an eyelet 68 by means of which the strap 66 is fixed to the upper 14.
In this way, by pulling the strap outwards or causing it to slide inside the eyelet 68 it is possible for the user to adjust the length of the strap 66 as considered most appropriate.
The eyelets 68 are fixed to rigid or semi-rigid plastic inserts suitably provided on the upper 14 of the boot 10. It is thus ensured that the eyelet 68, and consequently the base of the strap 66, does not become detached from the flap of the upper 14 onto which it is fixed.
Each toothed bar 62 also has lateral projections 65 which have the function of covering the side edges of the lever 64, once the latter has engaged with the toothed bar 62. In this way suitable protection is provided against accidental opening of the lever 64 following impacts with foreign bodies.
An important technical feature of the boot 10 according to the present invention consists in the particular arrangement of the closing fasteners 60.
If the upper is defined as having a first flap and a second flap, the fixing eyelets 68 of the fasteners 60 are positioned alternately on the first flap and second flaps.
As can be directly understood from
Examining also the top portion 16 of the upper 15 it can be noted that the eyelet on the side end of the element 34 is provided on the flap of the upper situated opposite to the flap of the upper on which the eyelet of the front plate 22 is positioned.
Said arrangement of closing fasteners does not affect the wearability of the boot; in fact it does not prevent the user from widening as far as possible the opposite flaps of the upper before putting on the boot and thereby increases the wearability of the boot as well as its comfort.
Advantageously the abovementioned arrangement of the closing fasteners also allows suitable tension to be exerted on the bottom flap of the upper so that it adheres better to the user's foot and calf.
Both the top flap and the bottom flap of the upper co-operate actively to close the boot and this means that there are not points where the closure is too tight or, on the other hand, points where the closure is too loose.
Moreover, the particular arrangement of the closing fasteners 60 reduces and practically eliminates the risk that the boot may open following an impact against solid bodies.
Finally, said closing fasteners may co-operate advantageously with the protection means 20 and 30 arranged in the vicinity of the leg-piece 16 of the boot 10.
In fact, they do not prevent sliding of the elements 24 and 34 inside the respective pockets and at the same time help ensure better adhesion of said protection means 20 and 30 to the top portion of the leg.
With regard to the embodiments of the boot 10 described above, the person skilled in the art may, in order to satisfy specific requirements, make modifications to and/or replace elements described with equivalent elements, without thereby departing from the scope of the accompanying claims.
