The invention relates to a ski boot with a ski boot shell and a ski boot sole, the ski boot sole having a front ski boot sole end, a rear ski boot sole end, a sole bottom and a free upper sole with which the ski boot sole projects forward, backward and / or laterally over the ski boot shell. The sole underside comprises a first contact area in which the ski boot stands with the ski binding closed on a support plate of a ski binding, and a second contact area with which the ski boot stands outside the ski binding on a flat surface for walking without skis. A width of the ski boot sole measured transversely to a ski boot sole longitudinal axis in the second contact area is greater or wider than a width of the ski boot sole in the first contact area. The ski boot is preferably a children's ski boot.

Especially children often have the problem that they can hardly walk with the ski boots, which have a relatively narrow outsole. You can easily lose your balance, fold over and get hurt or just fall over. This can reduce the joy and fun of skiing.

It would therefore be desirable to have a ski boot, especially for children, that facilitates walking without a ski and improves safety when walking.

This object is achieved by the invention with the ski boot according to claim 1.

One aspect of the invention relates to a ski boot, in particular a ski boot for children, comprising a ski boot shell and a ski boot sole connected to the ski boot shell. The ski boot shell may be in one or more parts and preferably consists of a plastic. The plastic can be hard and thus relatively little or not elastic, or at least partially have an elasticity, which facilitates walking especially when walking with the ski boot. If the ski boot or ski boot shell consists of several parts, they can be connected to one another via joints. Furthermore, the ski boot may comprise closing elements for closing the ski boot for skiing and walking, wherein the closing elements in the skiing position can close the ski boot more tightly than in the walking position.

The ski boot sole includes a front ski boot sole end, a rear ski boot sole end, a sole underside and a free upper sole, with which the ski boot sole protrudes forward, backward and / or laterally over the ski boot shell. The ski boot sole can also include pin receptacles in the front and / or rear area in order to be connected to pin bindings of a known type.

The sole underside comprises two separate footprints, a first footprint with which the ski boot, when held in the binding, rests on a tread plate covered by the tether, and a second tread region, preferably below the footwear, with which the ski boot is outside the footwear Skis rests on a flat plane. The second contact area preferably forms a rolling area in which the ski boot wearer can walk his foot while walking without skis following the natural walking motion.

The ski boot sole, preferably a support surface of the ski boot sole facing away from the ski boot sole in the second contact area on a substrate, is wider than the ski boot sole, respectively the bearing surface of the first contact area facing away from the ski boot shell on the contact plate of the ski binding.

That is, the ski boot sole can in the second contact area in an area that connects directly to the ski boot shell, have a width that differs from the width of the support surface of the ski boot sole in this area on the ground, the resting on the ground ski boot sole bottom of the Support surface may be wider than the ski boot sole directly adjacent to the ski boot shell and / or associated with the ski boot shell.

In this case, the ski boot sole can widen continuously from the ski boot shell to the sole bottom in the area of the second contact area, which is preferred, but the ski boot sole can also have a first portion of constant width starting from the ski boot shell, which then adjoins the first area widened second region in one or more stages or continuously to the sole bottom or support surface. The height of the second region may correspond, for example, to the depth formation of a profile on the underside of the sole of the second region approximately.

In a plan view from above on the ski boot sole, the second contact area or at least the support surface facing away from the ski boot shell of the second Aufstandsbereichs have any shape. Preferably, over the normal width of the ski boot soles protruding outer sides are arcuate, but are also other shapes, such as rectangular, square or triangular, doppelbogen- or S-shaped, etc.

The first contact area may be closer to the front sole end in the longitudinal direction of the sole than the second contact area. In addition, the first footprint may be above the second footprint at the ski boot standing on the level outside the ski. That is, the first footprint may be a greater vertical distance from the plane on which the ski boot is located than the second footprint.

The first and / or the second contact area may be planar, but at least the second contact area is preferably curved in a direction transverse to the sole width, that is, in the longitudinal direction of the ski boot from the front to the rear sole end, and / or over the width at least partially, preferably concavely arched in the direction away from the ski boot shell. At least in the direction of the width is also a convex or at least partially convex curvature of the second contact area conceivable, whereby the support surface of the second contact area depending on the load can widen again by the lateral ends of the second contact area, which extend in the sole longitudinal direction, elastically deformed become. In the context of the invention, the term curved also includes forms which are composed of substraights or have partial straight lines and arcuate sections.

The front footprint and the rear footprint may be formed of identical material and have identical hardnesses. It is preferred that the first contact area has a hard component with a hardness of preferably> 40 Shore D, preferably of> 45 Shore D and particularly preferably of> 50 Shore D. The second footprint may comprise a soft component having a hardness of preferably 60 to 90 Shore A, more preferably 65 to 85 Shore A, and most preferably 70 to 80 Shore A.

The width of the ski boot sole or the support surface of the ski boot sole in the first contact area may have a standard width of 62 mm. In the second contact area, at least the support surface of the contact area in a widest region can have a width of at least 64, preferably of at least 65 mm and particularly preferably of 67 mm. Widths greater than 67 mm are less preferred but not excluded.

If the second contact area, as described above, concavely curved at least in the longitudinal direction of the sole, and thus comprises a vertex, a crest line or a vertex surface, the apex, the apex line or in the longitudinal direction of the leading edge of the crest surface, at a level outside the Skis standing up ski boot from the front end of the ski boot sole a distance of 65 mm ± 10 mm, preferably from 65 mm ± 8 mm and particularly preferably from 65 mm ± 6 mm, have. The distance may also be smaller, for example 65 mm ± 4 mm or 65 mm ± 2 mm, which is less preferred. These measurements are especially for a children's ski boot with a total length of 217 mm, which corresponds to a shoe size 17.

Since children's shoes have different lengths, the dimensions given may also have different sizes. In general, if the distance of the vertex, the crest line from the front ski end is denoted by "a" and the ski boot sole length is denoted by "L", that "a" in about 30% ± 10%, preferably 30% ± 5% and more preferably 30% ± 3%. A ratio "a" / "L" would then be 0.3 ± 0.1, preferably 0.3 ± 0.05 and more preferably 0.3 ± 0.03.

The first contact area also comprises a contact point or a riot line or a footprint with which rests in the ski binding held in the ski binding on the footprint of the ski binding. This contact point, riot line or footprint may be 32 mm ± 8 mm, preferably 32 mm ± 5 mm, and more preferably 32 mm + 4 / -2 mm, from the front shoe sole end. A perpendicular distance of the contact point, the contact line or the contact surface of the first contact area running parallel to the contact area with the plane on which the ski boot stands outside the ski can be 5 mm ± 5 mm, preferably 5 mm ± 2 mm and particularly preferably 5 mm , amount. A substantially perpendicular distance from the point of contact of the first footprint on the footpad of the ski binding to a plane spanned by the front sole free upper side may be 17mm ± 1.5mm, preferably 17mm ± 1.2mm, and most preferably 17mm + 1 mm / -0.5 mm.

With the ski boot standing on the plane plane, a distance of the free upper sole side of the front sole end to the contact plane may be 23 mm ± 12 mm, preferably 23 mm ± 7 mm and particularly preferably 23 mm ± 3 mm.

The ski boot sole may include a separate front sole pad including the first footprint and the second footprint, and a separate rear sole pad. The front sole pad and the rear sole pad may together form a continuous ski boot sole or be spaced apart when mounted on the ski boot. At least the front Sohlenpad can be detachably connected to the ski boot or the ski boot sole or ski boot shell bottom, so that the first Sohlenpad can be replaced.

The ski boot may in particular be a child ski boot which should be marked with a "C" (children) according to the relevant ski boot standards.

A further aspect of the invention relates to a sole pad for a ski boot, in particular for a children's ski boot. The sole pad can be connected to the ski boot in a front area. The Sohlenpadunterseite comprises a first contact area, with which the ski boot can stand up in a binding on a footprint, and a second footprint, with the ski boot outside the ski on a flat surface, such as a flat plane, stands up. The second uprising area is for walking with the ski boot without skis. A width of the sole pad transverse to a sole longitudinal direction is wider in the second contact area than a width of the sole pad in the first contact area, the second contact area is preferably arranged below the football of the ski user or near the ball of the foot when the sole pad is connected to a ski boot. In particular, the underside of the second footprint lying on the ground may be wider, as already described.

FIG. 4:

Section view of the ski boot sole of the FIG. 1 in a ski binding held by the side.

The FIG. 1 shows a view from below of the sole 2, 3 of a ski boot 1, in particular a ski boot for children, with the sole 2, 3 which has been specially designed to improve walking with the ski boot 1 without skis.

The ski boot sole 2, 3 consists of a front sole pad 2 and a rear sole pad 3. In the embodiment, the front sole pad 2 is formed separately from the rear sole pad and each of the two sole pads 2, 3 is separately connected to the ski boot 1. In this case, the front sole pad 2 can be detachably connected to the ski boot 1, so that it can be exchanged for another sole pad, for example because of wear, damage or for adaptation of the ski boot 1 to a special ski binding.

Both sole pads 2, 3 have a profile to ensure a firm grip when walking with the ski boot 1 without skis in the snow or icy surface. The front sole pad 2 also has, as viewed from a front ski boot sole end 21, first contact area 4 and a second contact area 5, wherein the first contact area 4 is formed in the ski longitudinal direction X between the front sole end 21 and the second contact area 5. That is, the first contact area 4 is formed in the area of the toes of the user of the ski boot 1 or shortly behind, the second contact area 5 in the area of the football.

The first footprint area 4 is provided for the held in a binding ski boot 1 on a footing plate 11 of a ski binding 10 (see FIG. 4 ), while at the same time the second contact area 5 preferably neither parts of the ski binding 10 nor the ski touches itself. The second contact area 5 is optimized for walking with the ski boot 1 without skis. When standing on a flat surface ski boot 1, the front Sohlenpad 2 is only with a point, a line or an area of the second footprint 5 on the plane. As will be described later, the second sole pad 2 is shaped in such a way that the user can unroll as usual while walking with the ski boot 1 without skis in the region of the second contact area 5. For this purpose, in addition, the area of the ski boot sole between the front sole pad 2 and the rear sole pad 3 can be prepared to assist the unrolling with the foot when walking without skis, for example by an area with a material that unrolls at least slightly elastic deformation. In the exemplary embodiment shown, this region between the front sole pad 2 and the rear sole pad 4 comprises two reinforcing ribs 6 arranged transversely to the ski longitudinal direction X and spaced apart from one another.

How to get in the FIG. 1 a width B1 of the front sole pad 2 facing the viewer is smaller in the region of the first contact area 4 than a width B2 in the region of the second contact area 5. As a result, a surface of the second contact area 5 resting on the plane or the ground is larger, as a result the safety when walking without skis is increased. In order to further increase the size of the support surface, the profile of the second contact region 5 can be designed such that at a weight force from above at least individual parts of the profile are elastically deformed and thereby cause the enlargement of the support surface. For example, the tread may at least partially give the front sole pad 2 a concave shape, wherein at least the lateral ends transversely to the longitudinal direction X of the profile of the second or rear tread area 5 are elastically outwardly, ie away from a central longitudinal axis of the ski boot 1, by the pressure to be deformed.

The second footprint 5 may be made of a relatively soft material, for example, having a hardness between 70 Shore A and 80 Shore A, or comprise such a material. The first contact area 4, which should have little or no elastic deformation, can be made of a material having a hardness of greater than 40 Shore D, preferably greater than 50 Shore D, or comprise such a material. The first and the second contact area 4, 5 are preferably formed from plastic or plastics. Other materials or at least parts of materials other than plastic, such as glass, ceramics, metal, in particular for the first contact area 4 but less preferably also for the second contact area 5 are not excluded but included in the scope of the invention.

The FIG. 2 shows a side view of a lower part of the ski boot 1 of FIG. 1 , The FIG. 2 shows the ski boot 1 parked on a flat plane. The ski boot sole 2, 3 has a front ski boot sole end 21 with a free upper sole side 23 and a rear ski boot sole end 31. The sole bottom 22 is essentially formed by the front sole pad 2 and the rear sole pad 3, which in the exemplary embodiment are two separate sole pads 2, 3, which are not directly connected. Both sole pads 2, 3 have in the example shown a pronounced profile with which the grip of the ski boot 1 and the ski boot sole 2, 3 when walking without skis is improved compared to profileless ski boot soles.

The front sole pad 2 includes the first footprint 4 with a footprint 41 and the second footprint 5 with the footprint 51. The footprint 41, 51 may be or form a footprint, a ridge line, or a footprint formed two-dimensionally.

In the side view of the exemplary embodiment, the second contact area 5 or the profile in the area of the second contact area 5 is concave, at least in the middle area, transversely to a longitudinal axis of the boot, in order to enable or support a rolling movement of the foot when walking with the ski boot 1 without skis. This is not precluded that in the same area in a direction transverse to the shoe longitudinal direction X a concave curvature is formed, as already described above.

The second contact area 5 or the contact area 51 preferably has a distance a from the front sole end 21 at a length L of the ski boot sole 2, 3. It is preferred if a ratio of the distance a to the length L is 0.3 ± 0.01 , preferably of 0.3 ± 0.05 and more preferably of 0.3 ± 0.03. That is, the bale position or the contact point of the front sole pad 2 is about 30% plus / minus the corresponding tolerances of the length L of the ski boot sole 2, 3 behind the front end of the ski boot sole 21. With a sole length of 217 mm (children's shoe) is thus the footprint 51, for example, at 65 mm ± 5 mm behind the front sole end 21.

The FIG. 3 shows the sole region of the ski boot 1 the FIG. 1 in a view from the front. In turn, the profiling of the front sole pad 2, the first contact area 4 and at least the front part of the second contact area 5 can be seen. The second contact area 5 respectively has the profile around the second contact area 5 forms a slightly convex curvature in the image plane, so that at a force acting from above on the sole 2, 3 weight force is increased by an elastic deformation of the profile a ground contacting surface of the profile in this area.

A width B2 of the sole 2, 3 respectively of the front sole pad 2 in the region of the second contact area 5 is greater according to the invention than a width B1 in the region of the first contact area 4. Thus, the width B1 is given by the corresponding standard and is 62 mm, while the Width B2 has a value, for example, at least 65 mm, preferably 67 mm. Values greater than 67 mm are less preferred but also encompassed by the invention.

The FIG. 4 shows a sectional view of the sole region of FIG. 1 in the region of the first sole pad 2, wherein the ski boot 1 is held in a ski binding 10. The ski binding 10 may include pivotal sole holders, pins, or other fuses known in the art for holding the ski boot. The ski binding 10 has a support plate 11 which is shaped so that the sole 2, 3 with the first contact area 4 and the support surface 41 is supported on the support plate 11 when the binding 10 is closed. Behind the uprising plate a wedge-shaped cavity is formed which is delimited on three sides by a rear end of the uprising plate 11, the ski surface and the second contact area 5 respectively the profile surrounding the second contact area 5.

Further dimensions, which essentially result from the applicable standard for ski boots, especially children's ski boots, are given briefly for the sake of completeness. The standard also mentions tolerance values which are included in the scope of the invention. Also included are dimensions outside the values specified in the standard, which correspond to a maximum of the value of the standard with three times the tolerance, unless specified in the description of other dimensions or values or tolerances.

The free top 23 of the front ski boot sole end 21 has to a plane (see FIG. 2 ) a vertical distance b of about 23 mm. A vertical distance c between the support surface 41 of the first contact area 4 on the support plate 11 and the free upper side 23 of the front ski boot sole end 21 is approximately 17 mm. A vertical distance d between the support surface 51 of the second contact area 5 on the plane and the free surface 23 of the front ski boot sole end 21 is approximately 23 mm. A distance of the support surface 41 of the first support portion 4, which rests on the support plate 11 in the closed ski binding 10, has a distance e to the front ski boot sole end 21 of between 28 mm to 48 mm, preferably from 30 mm to 44 mm.
