Abstract

The invention relates to a ski boot, in particular a foamed ski boot comprising an inner boot (2) that is located in an outer shell (1) and a covering (8) that is applied to the inner face of the sole (7) of the inner boot (2) or on the upper face of an insole (25) that is located in the inner boot (2) for supporting the foot. To facilitate the introduction of the foot into the boot, the surface of the covering (8) that rests against the foot has a sliding region (20) with lower friction than the rest of the surface that rests against the foot and forms the remaining area (23) of the covering (8). The sliding region (20) extends at least over one part of the surface of the central foot section (16) of the covering (8), preferably over a large part of the surface of the central foot section (16) of said covering (8) and the remaining area (23) extends at least over part of the surface of the tarsus section (17), preferably at least over a large part of the surface of the tarsus section (17) of the covering (8).

Description

The invention relates to a ski shoe, in particular a foamed ski shoe, with an inner shoe arranged in an outer shell and with a covering for supporting the foot and with a sliding area for facilitating the application, which is arranged on the inner side of the sole of the inner shoe or on the upper side of an insole arranged in the inner shoe Entry into the ski boot.

The problem with ski shoes is that entry is only possible for the user with a relatively large amount of force and expansion of the outer shell of the shoe. This is particularly true for sporty ski shoes that have a relatively hard outer shell. Foamed ski shoes are particularly affected by this problem, which are designed in a comparatively very precise adaptation to the foot of the user.

To overcome this problem, ski boots with rear entry have already been proposed, the shell of which can be opened in the rear area. However, the foot of the user is given a less good grip by such ski shoes and these shoes are not particularly suitable for a sporty driving style.

A ski boot of the type mentioned at the outset is known from EP 0 839 464 A1. This ski boot has a strip-shaped sliding area on the inside of the inner boot, which extends from the upper end of the upper in the direction of the sole of the inner boot. A disadvantage of this ski boot is, among other things, that with this sliding area there is a risk that the hold of the user's heel will be reduced. The heel hold is particularly important for a ski boot. The effect of this sliding area is also limited.

From GB 345 622 A, a strip is attached to the back of the shoe upper to make it easier to get into a shoe, which strip is made of an elastic or flexible material and is attached to the sole in a region of the shoe that lies further forward. To put on the shoe, a finger is inserted into a loop between the strip and the shoe in the area of the back of the shoe in order to pull the shoe over the heel of the user. Such a design is not suitable for a ski shoe, since the heel hold in the ski shoe would be impaired. The object of the invention is to provide a ski boot of the type mentioned at the outset, which is also particularly suitable for a sporty driving style, the entry into the ski boot being made easier. According to the invention, this is achieved by a ski boot with the features of patent claim 1.

The inventive design of the surface of the cover facing the foot reduces the friction when entering the ski boot, which makes entry much easier. Nevertheless, the foot of the user can be provided with a sufficient hold when the ski shoe is closed due to the remaining area of the coating with a higher friction compared to the sliding area, so that the design according to the invention has little or no influence on the skiing properties of the ski shoe.

An advantageous embodiment provides that the rear end of the sliding area is spaced from the rear end of the cover, this distance being at least a large part of the length of the root section of the cover. Thus, the sliding area does not extend over the contact area of the heel of the user and the coating in the contact area of the heel has a higher friction than the sliding area in order to provide the heel with sufficient support.

In an advantageous embodiment it is further provided that the sliding area extends over at least part of the toe section of the cover, the sliding area advantageously being spaced from the front end of the cover. This results in an area with a higher friction in front of the front end of the sliding area, which counteracts a forward slipping of the foot while bumping the toes at the front end of the inner shoe. At the same time, getting into the shoe is made easier.

The sliding area can be formed by a single, contiguous area of the surface of the coating. Furthermore, the sliding area can also be formed by a plurality of separate partial areas, the partial areas being separated by areas with a higher friction. Further advantages and details of the invention are explained below with reference to the accompanying drawings. In this show:

Figure 1 is a schematic vertical section through a ski boot according to the invention. FIG. 2 shows a plan view of an exemplary embodiment of a cover attached in the inner shoe for supporting the foot of a ski boot according to the invention;

Fig. 3 is a schematic section along the line AA of Fig. 2;

4 shows a further embodiment of a cover for supporting the foot; Fig. 5 is a schematic section along the line BB of Fig. 4;

Fig. 6 shows an embodiment of a cover attached to an insole for supporting the foot of a ski boot according to the invention, in a schematic section corresponding to Fig. 3 and

Fig. 7 is a plan view of a conventional cover for supporting the foot to explain the different sections of the cover, with the schematically drawn contours of the impression of a foot resting on the cover and the hatched sections of the cover.

The ski boot shown schematically in FIG. 1 comprises an outer shell 1 in which an inner boot 2 is arranged. The outer shell is provided on the underside of its sole 4 in a conventional manner with an outsole 3 and is also equipped with a conventional wedge sole 5. The inner shoe 2 has a tongue 6. On the inside of the sole 7 of the inner shoe, a covering 8 is attached, for example glued on.

To close the ski boot, only schematically indicated buckles 9 are provided in FIG. 1.

The coating 8 can be divided into different imaginary sections, as will be explained below with reference to the conventional coating shown in FIG. 7. 7 shows a view of such a conventional cover for a right-hand ski boot from above, the contours 10 of the imprint of the foot of a user being drawn in and the different sections of the cover 8 being delimited from one another by broken lines 11, 12 and by different hatching are made clear. The dashed line 11 delimits the toe section 15, which extends in front of this line 11 to the front end 13 of the cover, from the midfoot section 16, which extends behind this line 11 to the dashed line 12. Line 11 connects the joints between the toes and metatarsals and runs to the side of the foot from the joints belonging to the large and small toes to the respective side edge 18, 19 of the cover 8 (perpendicular to the longitudinal extension of the cover 8).

The dashed line 12 delimits the metatarsal section 17 in front of it up to the line 11 from the tarsal section 17 lying behind it and extending to the rear end 14 of the cover. Line 12 connects the rear ends of the metatarsals and extends laterally of the metatarsals (i.e., the side of the foot) to the respective side edge 18, 19 of the cover (perpendicular to the longitudinal extension of the cover 8).

The definitions of the lines 11, 12 and thus of the sections 15, 16 and 17 of the cover 8 relate to an average formation of a foot with a size provided for the size of the respective ski shoe.

2 and 3 show a cover 8 according to a first embodiment of the invention in greater detail compared to FIG. 1, the cover being shown lying flat on the floor (after being fitted in the shoe, on the other hand, it is on the surface of the sole 7 of the cover plate) Liner 2 attached). In particular, the areas according to the invention with different friction can be seen from FIGS. 2 and 3. The foot facing, i.e. in the use position of the ski boot, the surface of the cover 8 on top has a sliding area 20. This sliding area 20 is formed by the surface of a film 21, which is applied to the top of a base part 22. For example, this film 21 can be sewn, glued, welded or embossed onto the base part 22. The part of the upper side of the base part 22 which is not covered by the film 21 and which thus forms the remaining part of the surface of the coating 8 is referred to as the residual area 23.

The part of the surface of the coating 8 which forms the sliding region 20 has a reduced friction, in particular sliding friction, compared to the part of the surface of the coating 8 which forms the remaining region 23 (ie there is a lower coefficient of friction, in particular sliding friction coefficient). So the rice Exercise, especially sliding friction of the material of a sock worn by the user (for example consisting of cotton, wool, acrylic, another synthetic fiber or mixtures thereof) is less with respect to the sliding area 20 than with the rest of the area 23. This is achieved in this exemplary embodiment by means of a film 21 with a low coefficient of friction, especially sliding friction. In contrast, the coefficient of friction of the material of the base part 22 is greater (at least on the upper side of the base part 22).

The dashed lines 11 and 12, which delimit the sections 15, 16, 17 of the coating 8 explained with reference to FIG. 7, are also shown in FIG. 3. The sliding area 20 extends over the majority of the area of the midfoot section 16 lying between the lines 11, 12. The rear end 24 of the sliding area 20 is spaced from the rear end 14 of the cover 8. In the exemplary embodiment shown, the sliding area 20 ends before the root section 17 lying behind the line 12. The distance between the rear end 24 of the sliding area and the rear end 14 of the cover 8 is preferably at least a large part of the length c of the foot measured in the longitudinal direction of the cover 8 17. The sliding area 20 preferably extends at least over a large part of the length b of the metatarsal section 16 measured in the longitudinal extent of the covering 8 and preferably over at least a large part of the maximum width d of the covering 8 measured perpendicular to the longitudinal extension of the covering 8.

In the exemplary embodiment shown, the sliding region 20 preferably further extends at least over part of the toe section 15 lying in front of the line 11 (which has a length a measured in the longitudinal direction of the coating 8). It is preferred here that the sliding area 20 is spaced from the front end 13 of the cover 8, i.e. part of the remaining area 23 lies in front of the sliding area 20.

In the exemplary embodiment shown, the remaining area 23 also extends over the entire root section 17 lying behind the line 12. At least the remaining area 23 extends over a part, preferably a large part, of the area of the foot root section.

In the exemplary embodiment shown, the sliding area 20 also does not extend all the way to the side edges 18, 19 of the covering 8, ie between the sliding area 20 and the side edges 18, 19 of the coating 8 are still sections of the remaining area 23.

The described design of the cover enables on the one hand a simplified entry into the ski boot and on the other hand ensures that the foot is adequately held against slipping. This is achieved by the remaining area 23. The contact area of the heel lies in the root section 17 of the cover 8, over the surface of which at least the rest of the area 23 extends. The section of the remaining area 23, which is preferably in front of the sliding area 20, counteracts a slipping of the foot forward.

Another exemplary embodiment of a coating 8 according to the invention is shown in FIGS. 4 and 5. Here, the sliding area 20 is formed by a plurality of separate partial areas which are spaced apart from one another by sections of the remaining area 23. Again, the partial areas of the sliding area 20 are formed by the surfaces of foils 21 which are applied, for example sewn, to the top of a base part 22 of the covering 8.

The foils 21 are preferably air-permeable, for example provided with perforations.

Instead of forming the sliding area 20 by means of one or more applied foils, it would also be conceivable and possible to form the sliding area in that a base part 22 of the coating on its upper side either with a coating forming a coherent area or with a plurality of coatings each forming a partial area is provided. The surfaces of these coatings facing the foot in turn have lower coefficients of friction than the uncoated regions which form the remaining region 23 of the base part 22.

It would also be conceivable and possible to provide the covering 8 on its surface facing the foot during production with areas of different friction in order to form the sliding area 20 and the remaining area 23. For example, in this case the coating 8 could be formed as a plastic injection molded part from two different plastics having different coefficients of friction. The cover 8 or the base part 22 of the cover 8 can consist, for example, of leather, synthetic leather, plastic, a fabric or flow material or combinations thereof.

The coating 8 can be fixed directly on the inside of the sole 7 of the inner shoe 2, as shown in FIG. 1. An insole is often also inserted into the inner boot 2 of a ski boot. In this case, the cover 8 would be fixed on the top of the insole. For example, the cover 8 could be glued to the insole 8 for this purpose.

An embodiment in which the cover 8 is attached to the top of an insole 25 to be arranged in the inner shoe 2 is shown schematically in FIG. 6. The cover 8 in turn has a base part 22, which is attached to the upper side of the insole 25 in regions and is provided with a film 21 on its upper side to form a sliding area, which has a lower coefficient of friction than the material of the base part 22. This in turn forms a sliding area 20, which can be shaped, for example, in the manner shown in FIGS. 2 and 4.

Such an insole 25 can, for example, initially be flat as a blank and is adapted to the shape of the foot by the action of heat.
