Definitions
- the present invention relates to a ski boot.
- the present invention relates to a multi-purpose ski boot, which may be used for mountaineering and for downhill skiing.
- ski boots in both sports have a very similar basic structure, they significantly differ in the lower part of the boot, which is traditionally intended to be fixed to the back of the ski by means of specific ski -binding devices for each sport .
- the ski boots in both sports essentially consist of a rigid shell made of plastic or composite material, which is shaped so as to accommodate the foot of the skier and has its lower part specifically structured to be fixed to the back of the ski by means of specific ski-binding devices; of a rigid cuff made of plastic or composite material, which is shaped so as to embrace the lower section of the skier' s leg from behind and is hinged to the upper part of the shell so as to rotate/swing about a transversal reference axis, which is locally substantially coincident with the articulation axis of the ankle; of an inner liner made of soft and thermal insulating material, which is removably inserted into the shell and cuff, and is shaped so as to envelop and protect both the foot and the lower section of the skier's leg; and lastly of a series of manually-operated closing buckles, which are conveniently distributed on the shell and cuff, and are structured so as to selectively close/ tighten the shell and cuff so as to
- the structure of the ski-binding device substantially varies from one sport to the other. This implies that the shape of the lower part of the shell changes radically depending on whether or not the ski boot is intended for mountaineering or for downhill skiing.
- the shell of the ski boot is equipped at the bottom with a front sole and with a back heel, which are specifically structured/shaped to be coupled to, respectively, a toe-piece and a heel-piece which are integral with the back of the ski, and are specifically structured to allow the skier to carry out movements which are typical in downhill skiing or movements which are typical in mountaineering.
- the dimensional specifications of the sole and heel of the ski boot are regulated by two separate international sets of incompatible standards, one which is binding for downhill ski boots (in this case standard ISO 5355) and the other which is binding for mountaineering ski boots (in this case standard ISO 9523 and the dimensional specifications required for coupling to Dynafit mountaineering ski -binding devices or the like) .
- ski boot manufacturers have developed and marketed ski boots in which the front sole and back heel are removably fixed to the lower part of the shell by means of a series of locking screws .
- This contrivance allows equipping the boot with two separate front sole and back heel sets, which can be alternatively positioned on the lower part of the shell depending on the skier's needs.
- the first front sole and back heel set is specifically structured/dimensioned to meet international standard ISO 5355, which is binding for downhill ski boots
- the second front sole and back heel set is specifically structured/dimensioned to meet international standard ISO 9523, which is binding for mountaineering ski boots, and more particularly, the dimensional specifications required for coupling to Dynafit mountaineering ski -binding devices or the like. Mountaineering ski-binding devices are briefly described for example in European Patent EP-0199098.
- a ski boot equipped with two separate removable front sole and back heel sets is described in application PCT WO2009/003904.
- ski boots Unfortunately, the use of these types of ski boots has underlined certain criticalities , which have strongly penalized their distribution on the market. According to more careful, expert skiers, the above- described ski boot is indeed not capable of providing the user with the same dynamic behaviour and reactivity as a regular ski boot with a sole and heel made in a single piece with the shell, with all the problems this involves .
- Aim of the present invention is to produce a ski boot which is compatible with downhill ski-binding devices and with mountaineering ski-binding devices, and which is capable of providing the skier with the same dynamic behaviour as that of a traditional ski boot with sole and heel made in a single piece with the shell.
- a ski boot as defined in claim 1, and preferably, though not necessarily, in any one of the claims dependent thereon.
- FIG. 1 shows a side view of a mountaineering ski boot realized according to the teachings of the present invention, in a first operating configuration and with the lower part sectioned along the centre plane ;
- FIG. 2 shows a section view of the ski boot shown in figure 1, according to the sectional line D-D;
- figure 3 shows a partly exploded view on enlarged scale of the lower part of the ski boot shown in figure 1;
- FIG. 4 shows an enlarged and partly exploded view of the lower part of the ski boot shown in figure 1, in a second operating configuration
- figure 5 shows a section view of the ski boot shown in figure 4, according to the same sectional line used in figure 2.
- number 1 indicates as a whole a ski boot structured to be coupled both to a specific ski-binding device for downhill skiing and to a ski-binding device for mountaineering.
- Ski boot 1 essentially consists of a rigid outer shell 2 made of plastic or composite material, which is shaped so as to accommodate the whole foot of the user; of a removable front sole 3, which is fixed in a rigid and stable although easily removable manner, to the lower wall 2a of shell 2, more or less at the tarsal- phalangeal area of the foot, and which cantilevered juts out beyond the ogival tip of shell 2; of a removable back heel 4 which is fixed in a rigid and stable although easily removable manner to the lower wall 2a of shell 2, at the heel of the foot; and of a rigid cuff 5 made of plastic or composite material, which is preferably substantially C-shaped so as to embrace the lower section of the user' s leg from behind, and is hinged to the upper part of shell 2 so as to freely swing about a transversal reference axis A which is locally substantially perpendicular to the vertical centre plane M of the ski boot (that is perpendicular to the plane of the sheet in figure 1) , and is also locally substantially coincide
- cuff 5 is freely rotationally fixed to shell 2 by means of two connecting hinges 6 which are arranged on the external and internal lateral sides of shell 2 and cuff 5, aligned along axis A, so as to allow cuff 5 to freely swing on shell 2 while always remaining on a reference plane which is orthogonal to axis A and substantially coincident with the centre plane M of the boot .

- This longitudinal gap allows the upper part of shell 2 to temporarily widen so as to facilitate the insertion of the foot of the user into liner 7.
- the protective tongue 8 is substantially L-shaped and extends grazing to shell 2 in the area immediately above the instep of the foot and the tibia-astragalus junction of the ankle, and then ascends along the leg up to reach and insert below the cuff 5, so as to cover the lower section of the tibia.
- ski boot 1 also comprises one or more manually-operated, mechanical ski- boot closing devices 9 which are structured so as to selectively close/tighten shell 2 and cuff 5 so as to immobilize the user's leg inside boot 1, or better, liner 7.
- the mechanical ski -boot closing devices 9 preferably, though not necessarily, consist of a series of lever closing buckles 9 which are arranged crosswise on shell 2 and/or on cuff 5 and/or on protective tongue 8, substantially astride the longitudinal gap of shell 2, so as to selectively close/tighten shell 2 and cuff 5 to stably immobilize the user's leg inside liner 7.
- Ski boot 1 is preferably also provided with a manually-operated cuff locking device 10 which is structured so as to selectively:

- the transversal stiffening plate 12 of shell 2 could be shaped/ structured so that the middle inner portion thereof can emerge/crop out on the outer surface of the lower wall 2s of the shell, astride the vertical centre plane M of the boot, and substantially at the metatarsal-phalangeal area of the foot.
- the dimensions of this middle portion are to be sufficient to ensure stable resting of the removable front soles 3 and 3' on the transversal stiffening plate 16, 36.
- At least one of the main anchoring screws 15 is adapted to lock/retain any one of the removable front soles 3 and 3' in abutment on the lower wall 2a of the shell, by engaging the monolithic body formed by socle 13 or 33 and slab of elastomeric material 14 or 34, and the transversal stiffening plate 16, 36 embedded within socle 13 or 33, in a pass -through manner, to then be screwed directly into the beneath located emerged central portion of the stiffening plate 12 of shell 2.
