Description
Background of the Invention
The present invention relates to a ski boot with a mechanism for securing a foot instep and heel.
As is known, in ski boots devices which perform the securing of the foot instep are currently employed; such devices are generally composed of a presser, on which presser, by means of pushing elements, cables or the like, a force is exerted which tends to exert a substantially vertical pressure with respect to the foot instep in order to perform the securing of the foot itself.
With such an embodiment, which is universally adopted, it turns out that the foot is not, in most cases, sufficiently restrained against the lateral movements, so that it is necessary to exert even high pressures in order to obtain an acceptable securing of the foot, with obvious discomfort to the user.
Another disadvantage which can be found in the prior art is furthermore represented by the fact that the securing action exerted on the foot unavoidably tends to shift the foot towards the rear part of the boot, where it is not always possible to create a securing force capable of conveniently securing the foot without causing discomfort to the user.
Summary of the Invention
The aim of this invention is indeed to obviate the above cited disadvantages by providing a locking device which can act simultaneously on the instep and on the heel of the skier's foot, obtaining a securing action capable of immobilizing the skier's foot, without, however, causing discomfort to the user.
Within the above aim, a particular object of the invention is to provide a mechanism for securing the foot instep and the heel, which is also capable of restraining the foot laterally, thus distributing uniformly on the foot itself the action which can be exerted by means of the presser of the foot instep.
Another object of the present invention is to provide a securing device which, though presenting remarkable functional characteristics, is structurally simple and has a simplified operation.
A not least object of the present invention is to provide a device which can be easily obtained from elements and materials which are commonly available on the market, and which, furthermore, is competitive from a merely economical point of view.
The above aim, as well as the objects referred to and others which will become apparent hereinafter, are achieved by a ski boot with a mechanism for securing the foot instep and heel, according to the invention, which comprises, within the shell of a ski boot, a tension element connected to a traction device accessible from the outside of said boot, characterized in that said tension element defines a rear section rearwardly encircling the area of the heel and associated with a band section extending transversely above a foot instep presser, said band section being, at one of its ends, associated to said boot in the area of the sole of the skier's foot.
Brief Description of the Drawing
Further advantages and characteristics will become apparent from the following detailed description of a ski boot with a device for securing the foot instep and heel, which is illustrated, by way of example only, in the accompanying drawing, in which the single drawing FIGURE represents a ski boot with the device applied thereto, according to the invention.
Description of a Preferred Embodiment
With reference to the single drawing figure, a ski boot is illustrated, generally indicated with the reference numeral 1, which boot advantageously, but not necessarily, is of the rear-entry type, and comprises a shell 2 to which are pivotably associated, in a manner known per se, a front quarter 3 and a rear quarter 4. The boot 1 has an instep area 2a, a heel area 2b, a sole area 2c and a wedge area 2d of the sole 2e.
Inside the ski boot is provided a tension element, advantageously consisting of a cable 10, which cable, at one end, is connected to a traction mechanism or device which can consist of a reel 11, such as is illustrated in the drawing, or, if required, by a lever or any other mechanism capable of exerting the required traction on cable 10.
The cable 10 has an initial section 10a connected to the reel 11, which unwinds on a first transmission element composed of a small pulley 20, which pulley is generally provided substantially at the rear lateral area of the shell.
After the initial section 10a, the cable 10 defines a first lateral section 10b, to which a front section 10c follows, which unwinds above presser 21, substantially at the top part of the foot instep presser 21. The instep presser has a first upper zone 21a and a second lower zone 21b.
After the front section 10c, the cable 10 defines a second lateral section 10d, which section is opposite with respect to the first lateral section 10b, and unwinds on a second transmission element 22, which can consist, for example, of the front quarter 3 hinge means.
The cable then defines a rear section 10e which develops from said second lateral section 10d and rearwardly encircles the area of the heel and, by means of the interposition of a third transmission device 23, which is essentially opposite to the second transmission device 22, is associated with a terminal section at a beginning portion 10g thereof and which can consist of the cable itself or by a band section 10f which extends transversely above the foot instep presser,in a zone which is inferior with respect to the engagement zone of the front part 10c of the cable, thus obtaining an action on the foot instep presser in two areas remote from each other.
An important peculiarity of the invention is constituted by the fact that the band element defines an increasing useful width, starting from the connection area 10g to the rear section 10e, towards the opposite end or ending portion 10e, where the band element is fixed to the boot substantially at the area wedge area 21 of the sole of the skier's foot.
The band element is preferably made of flexible plastic material, in order to adapt to the configuration of the part of the foot upon which it acts. Furthermore, the band element acts above the presser in rigid material so as to uniformly distribute the load on the foot instep.
At its terminal end, which is the widest end, the band element can be fixed to the wedge provided inside the boot or, if required, is fixed directly to the shell, so that in both solutions it is located substantially at the area of the sole, in such a manner that it encircles, even laterally, the skier's foot.
With this configuration, the forefoot is practically completely embraced, thus exerting a pressure action which is not only vertical, but is also capable of restraining the foot even laterally, thus contributing to a perfect securing of the foot, together with the fact that the cable also engages substantially at the heel area, performing a complete and uniformly distributed securing.
The use of the device is extremely simple; in fact, if cable 10 is put under tension, by means of the transmissions described above, a securing action is performed simultaneously on the forefoot and on the upper part of the foot instep, combined with a securing action on the foot exerted in the area of the heel, where, if required, it is possible to provide a rigid heel element or another element capable of distributing the pressure exerted on the cable substantially proximate to the heel area.
From the above description, it can be seen that the invention achieves the proposed objects, and in particular the fact is stressed that the presence of the band element encircling the foot allows for a perfect securing action without generating excessive forces, which may be a source of discomfort to the user, together with an action on the foot instep presser, which is carried out in two separate areas.
In practice, the materials employed, so long as compatible with the specific use, as well as the dimensions and the contingent shapes, may be any according to the requirements.
