The present invention relates to a sports boot, particularly for skiing, skating, or snow-boarding, according to the characteristics set out in the preamble to the main claim.
TECHNOLOGICAL BACKGROUNDWhen practising these sports, it is known to use sports boots comprising a shell and a bootleg with a rigid structure. However, although on the one hand sports boots of this type help significantly to protect the sportsperson's feet and ankles, on the other hand, they are not very suitable for following his movements in use. This problem appears in particular when it is necessary to bend the leg forwards, for example, when performing a turn. As a result of the bending, a space is in fact created between the leg and the rear portion of the bootleg (or of an inner boot housed therein), which leads to less precise control of the equipment, as well as the undesirable possibility of snow entering the boot. This limitation is particularly evident with sportspersons who have quite thin legs, for whom it is sometimes not possible to achieve a fit of the upper part of the bootleg against the calf, even in rest conditions. A sports boot having the features outlined in the preamble of the main claim is disclosed in EPA 371915, in EPA 477817 and in the U.S. Pat. No. 4,888,889.
DESCRIPTION OF THE INVENTIONThe problem underlying the present invention is to provide a sports boot, particularly for skiing, skating or snow-boarding, which is designed structurally and functionally to overcome the limitations explained above with reference to the prior art mentioned.
This problem is solved by the present invention by means of a boot formed in accordance with the appended claims.
BRIEF DESCRIPTION OF THE DRAWINGSThe characteristics and the advantages of the invention will become clearer from the detailed description of some preferred embodiments thereof, described by way of non-limiting example with reference to the appended drawings, in which:
FIGS. 8 to 11 are schematic, perspective, side elevational or rear elevational views of respective variants of a component of the boot of
FIGS. 19 to 21 are schematic views of variants of the boot of
With reference initially to FIGS. 1 to 6, a first embodiment of a sports boot formed in accordance with the present invention, is generally indicated 1. The boot 1 is a ski boot and comprises a shell la with a rigid structure, to which is fixed a bootleg 2 in relation to which, and also with reference to the normal use of the boot 1, an opening 2a and, adjacent thereto, a rear portion 3 and a front portion 4, are identified in the boot 1. In this description, in particular with reference to the embodiments described below, the definition of the extent of the terms “front portion” and “rear portion” is not limited to the bootleg 2, but also extends to the corresponding front and rear regions of the boot 1. In particular, the front portion 4 may also include the front region of an inner boot inserted in the bootleg 2, and the rear portion may include the rear region of the shell as described below in the third and in the fifth embodiments of the invention, respectively.
According to a principal characteristic of the invention, in the region of the opening 2a of the boot 1, there is a support element 5 which can pivot between a first operative position, in which it is close to the rear portion 3 (
The support element 5 in this first embodiment is housed inside the bootleg 2, has a rigid structure, and is substantially cradle-shaped with a curvature similar and corresponding to that of the rear portion 3 of the boot 1.
The boot 1 also comprises connection means, generally indicated 6, acting between the support element 5 and the front portion 4 so as to bring about the pivoting of the support element 5 between one operative position and the other as a result of any forward movement of the front portion 4.
The connection means 6 in turn comprise a first strap 7 which is wrapped around the support element 5, between the latter and the rear portion 3, so that, as a result of tensioning of the first strap 7, the support element 5 is moved from the first operative position to the second.
In a preferred embodiment of the invention shown in particular in
The connection means 6 also comprise a second strap 11 which is advantageously guided through the guides 8 and closed onto itself around the front portion 4 so as to tighten the first strap 7 as a result of a forward movement thereof. The degree of tensioning both of the first strap 7 and of the second strap 11 are intended to be adjustable by the user, preferably by means of touch-close pull fastening means, indicated 12 and 13, respectively. When the front portion 4 is bent forwards because of the bending performed by the sportsperson, for example, when executing a turn, the movement of the front portion brings about translation, in the same direction, of the second strap 11 and of the first strap 7, connected thereto by means of the pair of guides 8. The tensioning of the first strap 7 leads to pivoting of the support element 5 from the first operative position to the second. The support element 5 thus remains close to the sportsperson's leg, following it in its movement and taking up the variation in cross-section which occurs in the region of the opening 2a as a result of the forward bending of the front portion 4. Contact between the sportsperson's leg and the boot 1 is thus maintained around the entire periphery of the leg.
It should be noted that, in the embodiment described, the amplitude of the pivoting of the support element 5 is increased by the particular arrangement of the two straps 7, 11, guided by the guides 8.
A second embodiment of the invention is shown in
It should be noted that, in this solution, the path of the first strap 7 is advantageously entirely inside the bootleg 2.
In conventional manner, both the boot 1 and the boot 20 comprise an inner boot 25, housed in the bootleg 2 and made of soft material in order to house the sportsperson's foot and leg comfortably. According to a characteristic of the present invention which tends to favour constant contact between the sportsperson's leg and the boot, preferential yielding regions are provided on the inner boot 25 to enable its top portion 26 to pivot simultaneously with the pivoting of the support element 5.
FIGS. 8 to 11 show various alternative embodiments of inner boots (all indicated 25) which have been developed to respond to this functional requirement. In
In FIGS. 8 to 11, respective arrows F indicate the movements of the preferential yielding regions brought about as a result of the pivoting movement of the support element 5 between the first and second positions of
In the preferred embodiments described up to now, the support element 5 is articulated to the bootleg 2. In particular, it is fixed pivotably to the bootleg 2 by pin fixing means 35 which are provided on the opposite sides of the rear portion 3 and which permit pivoting between the above-described operative positions, by rotating about an axis X. The height of the support element 5 relative to the bootleg 2 is preferably also adjustable, owing to the provision of holes 36 formed at different heights in the support element 5, each hole being able to house the fixing pins 35.
With reference to
In a third embodiment of the invention, shown in
The first strap 7 of the boot 100 is restrained inside the bootleg 2 by means of a rivet at a first 9a of its ends and carries a guide ring 108 at the opposite, free end 9b. A first end 11a of the second strap 11 is also restrained inside the bootleg 2, on the opposite side to the end 9a of the first strap, the second strap being led out of the bootleg 2 through the guide ring 108 in order to extend around the entire opening 2a and to be led back through the guide ring 108 and is finally closed onto itself by means of touch-close pull fastening means 13. It should be noted that the combination of the straps 7, 11, in which the second strap 11 extends through the guide ring 108 twice, permits a more stable arrangement of the straps around the bootleg 2.
To enable the second strap 11 to extend from the inside of the bootleg 2 to the outside, the profile of the bootleg 2 in the region of the opening 2a has a recess 109a to which a symmetrically opposed recess 109b corresponds.
In the rear portion 3 of the boot, the second strap 11 may also be led into the bootleg 2 through suitable slots 110 formed therein.
A fifth embodiment of the invention is shown in FIGS. 16 to 22 showing a boot 200 the components of which are indicated by the same reference numerals as in the previous embodiments.
The boot 200 comprises a shell la to which a bootleg 2, which extends only partially around the shell la, is articulated in the front portion 4 of the boot. The shell la has, in the rear portion 3 of the boot which is not covered by the bootleg 2, a region of preferential deformability defining a seat 201 delimited at its opposite sides by ribs 202. The boot 200 further comprises a support element 5 fixed to the outside of the shell la close to the rear portion 3 so as to be housed in the seat 201. As in the previous embodiments, the support element 5 can pivot towards the front portion 4 as a result of a forward bending thereof.
To allow the support element 5 to pivot, the shell la has a first slit 203 extending substantially vertically along the seat 201 and open at the top of the opening 2a. The side edges 204 of the first slit 203 are preferably turned outwards (see
The flexibility of the shell la can also advantageously be increased by the provision of a pair of symmetrical lateral slits 206, the depth of which may be selected in dependence on the desired degree of flexibility (variants shown in broken outline, indicated 206a, 206b in
The support element 5 may be connected to the shell la by means of a fixed connection, for example, by means of a boss 207 provided at its end remote from the opening 2a, below the slit 203. In this case, the pivoting of the support element 5 is permitted by utilizing the intrinsic flexibility of the material of which it is made.
As in the previous embodiments, the support element 5 is connected to the front portion 4 of the boot by connection means which can adopt all of the configurations described above. They may therefore be of the type described with reference to the boot 1, or the boot 100, which are shown schematically by way of example in
In a variant of the boot 200, shown in
The boot 200 is preferably equipped with an inner boot 25 of the type described above with reference to
During forward bending of the boot 200, and hence during the corresponding and simultaneous pivoting of the support element 5, the shell la is deformed in the region of the slits 203, 206 so as to follow the progress of the bending. It should be noted that, in this way, no empty spaces are created between the user's leg and the rear portion 3 of the boot, permitting even more precise control during turning and also preventing the undesired entry of snow into the boot.
The present invention thus solves the problem posed with reference to the prior art mentioned, at the same time offering many other advantages, amongst which is improved sensitivity in the control of turns for the sportsperson.
