EP2042049A1 - Sports shoe, in particular downhill ski boot and cross-country ski shoe - Google Patents

Abstract

The sport shoe has a positioning unit with a clamping unit (5), which is connected with a front sole plateau (3) and with a rear sole plateau (4) in a force-fit manner. The central point of the cartridges (7) lies on an oscillating curve running from an instep to the soles and the angle is estimated in values between 20 degrees to 60 degrees from the instep to the sole.

Description

The invention relates to a sports shoe according to the preamble of claims 1 to 4 and a sports shoe according to the preamble of claim 15.

From the prior art, a variety of sports shoes, in particular alpine ski boots, according to the preamble of claim 1 is known.

The US 6065228 A describes a sports shoe, on the underside of various sole parts can be mounted interchangeable. In this way, such a shoe can be converted to the requirements of various sports. An alpine ski boot, a snowboard boot or a touring boot can be formed here. In this sports shoe, which can be adapted to various sports, it is also possible to provide a form-coded middle part which prevents inappropriate combinations. This molded middle section is formed by connecting bars located between the front and rear sole plates. As a result, a purpose-foreign mixing of different sole parts belonging to different sports avoided.

From the DE 198 53 077 A1 For example, an alpine ski boot with a pliable shaft is known in which the design of the sole allows the foot to flex while walking. As is absolutely necessary with alpine ski boots, this flexible sole has, in a commercial ski binding suitable, rigid end pieces. The flexible sole here has an elastic middle sole portion, wherein the flexibility of this elastic sole member can be prevented by means of a locking device. It is thus possible to make this sole in its central region either elastic or relatively firm. This is made possible by means of an externally accessible lever whose respective position activates or deactivates the locking device via bolts which are loaded by compression springs.

With this shoe, a prompt switchover from a flexible sports shoe to a comparatively inflexible ski boot is thus possible. The reverse process is just as easy to reach.

An individual adjustment of the stiffness of the sole is not possible in both cases.

In this prior art brought in the WO 01/35780 A1 described winter sports shoe or the combination of a winter sports shoe and a ski a decisive change.

This winter sports shoe is characterized by the fact that the shoe front part of the outer shoe is largely decoupled from the rear part of the outer shoe by means of a, in the metarsal region (metatarsal between tarsus and toes) provided, flexible transition region.

This allows the forefoot to roll in the footpad area about an axis of rotation transverse to the longitudinal axis of the ski boot. The outer shoe shank and the molded-on side parts up to the metatarsal area are essentially unobstructed, so that a bending force can be introduced into this area of the sole by means of the outer shoe shaft.

In addition to the immediately obvious advantage that the cumbersome walking in ski well outside the ski binding is greatly facilitated by the bending of the sole, resulting in skiing itself even a relief for the knee joints. Because with an inflexible shoe sole unavoidable displacements of the body's center of gravity during the ride can be compensated mainly only by a flexion of the knee. In contrast, in the case of a flexible sole, the position of the center of gravity of the body can be additionally corrected by means of a flexion of the foot in the metatarsal area.

A further improvement of this fundamentally new concept is the ski shoe known from WO 02/094047 A1. Here, there are essentially special embodiments of the sole which is flexible in the metatarsal region, as already described in US Pat WO 01/35780 A1 are described. Furthermore, different solutions are pointed out in this document for the problem of the flexible shell part to be designed in the forefoot area. In addition, various new shapes, constructions and design studies of the liner are presented.

Although this new design of the construction of ski shoes allows a much better adaptation of the shoe to the different foot shapes occurring in practice, but here also wishes remain open, especially the consideration of the individual weight of the user of the ski boot.

Also the approximation of the perceived body weight, for example in terrain, by a modified damping effect of the shoe sole is another desirable option.

Cross-country skiing is one of the Nordic disciplines. He has always been a domain of the Scandinavians. This is understandable, because before the invention of the car in Sweden and Finland, but especially in Norway with its huge distances, cross-country skiing was absolutely vital. For example, cross-country skiing has involved the transport of food and drinks. This is because the large, extensive plains in these countries are covered with snow five months a year.

Already some 5,000 years ago, the Scandinavians hunted and transported their prey on skis. Today, the former means of transport has become a popular recreational sport.
Cross-country skiing is the number one sport in Norway, Sweden and Finland.

Only late, at the beginning of the sixties of the last century, did Schilanglauf find its way from the far north to Central Europe. Previously, it was operated in our latitudes only by a few outsiders.

From about 1965, more and more winter sports fans in Germany, Austria and Switzerland liked the cross-country skiing. After 1970, increasingly usable cross-country skis went into mass production. Anyone who had previously struggled on wide, wooden monsters could now run on narrow and very light plastic skis. A cross-country equipment weighs only about 3 kilograms, while an alpine ski equipment weighs up to 10 kilograms.

Nevertheless, two hours of cross-country skiing can be exhausting, especially for beginners. For cross-country skiing, as is hardly the case in sports, almost every single muscle of the body required. In addition to the legs, the arms and trunk have to do heavy work. The arms are the starting point of the achieved speed. Experts say that running starts in the thumb and ends in the feet. Cross-country skiing is a combination of endurance and muscle power. The most important technique is the diagonal step in which the whole body is in motion. The arms swing diagonally to the repulsion of the legs. The arms have to cooperate and push the long sticks forward, with the hull having to stabilize the body.

Since the beginning of the Olympic Winter Games in 1924, cross-country skiing has been an integral part of the Olympic program. Since 1952 there are also competitions for women.

As a further development, the semi-skate step, which was systematically used by the Finn of Siitonen, saw the introduction of a new locomotion technique known as skating in the 1980s. After a polemic phase on the admissibility of the skating techniques in competition since then competitions either in the classical style, the parallel skiing in a groomed trail, or in free style (usually skating) carried out.

Depending on the cross-country technique used, specialized equipment is used.

In the case of classic cross-country skis, the middle area, the so-called climbing zone, is prepared so that it adheres to the snow if there is contact, so that an impression can be made to the rear.

Skating skis, which are shorter and slightly curved than the classic cross-country skis, have no climbing zone. The shoes have a rigid sole and a laterally stabilized shaft. They enclose the ankle a little higher around the foot, so that it is better supported when moving sideways.

In addition to the special design of skis for the various techniques of cross-country skiing, various variants of shoes have been recently presented, each of which offers advantages for the cross-country skiing technique in question.

So was the DE 690 02 425 T2 a sport shoe for running for cross-country skiing of the type having a flexible shaft, provided with a rear reinforcement and having a stiff collar articulated on the rear reinforcement of the shoes and intended to surround the lower part of the leg (Preamble of claim 1).

This known sports shoe should be improved so that both the legroom in the longitudinal direction of the shoe is guaranteed while running, as well as a good lateral support of the leg of the user is achieved.

This object is achieved according to the features in the characterizing part of claim 1, characterized in that the shaft of the shoe is a lower shoe, i. a shaft whose rigid parts do not extend higher than the ankles, and in that the joint of the stiff collar on the shaft is at the level of its upper end, the collar retracting from its joint beyond the upper end of the shaft extends above.

Although this shoe provides an improvement over the prior art in terms of the ankle area resulting lateral support, this lateral support offers little adaptability and comfort in the rotational movement of the ankle. In addition, the flexibility of the sole is unchanged compared to conventional shoes.

Furthermore, from the EP 0 711 517 B1 a stiffening insert for sports shoes, especially cross-country skiing, known, consisting of a one-piece plastic shell with a heel surrounding heel part, both sides of the heel part continuing, projecting into the midfoot area side parts and a towering over the ankle shaft part.

In this stiffening insert, the shaft part is separated from the side parts by side slits and the heel part by a heel slot, wherein a connecting web for articulation of the shaft part at the heel or side parts remains between two substantially heel and side slits extending to the ankle region.

This stiffening insert is indeed more convenient than that on which the DE 690 02 425 T2 known sports shoe attached additional lateral support, to the associated sports shoe, however, no improvements are given.

The present application therefore has the object, on the one hand, of providing a sports shoe in which the rigidity can be adjusted in a simple manner.

The sports shoe according to the invention is also based on the one hand to provide better grip for the foot on the one hand to practice different sports and on the other hand to facilitate the natural movement of the foot when practicing this sport and the entry.

The first object is achieved by a sports shoe according to one of the independent claims 1 to 4.

The main advantage of the sports shoe according to the invention lies in the fact that the mechanism with which the flexibility of the sole can be adjusted is relatively easily accessible and less sensitive to damage. In addition, it is possible to apply relatively high actuating forces via the raised podium-like sole plateaus.

The advantages of an adjustable flexible sole for alpine footwear are well known and well known WO 01 // 35780 A1 and the WO 02/094047 A1 described in more detail.

Another advantage of the sports shoe according to the invention is also therein. that the claimed mechanical structure allows a lightweight construction, especially when using carbon fiber composites and light metals.

The second object is achieved by the features of claims 15 and 16, respectively.

Although the plastic shells used to dress the foot used in the prior art are made of relatively soft material, but still set this process a certain unpleasant resistance when bending the sole of the foot. Likewise, the sole of the prior art cross-country ski shoes is usually quite inflexible. However, since the binding element which establishes the connection to the cross-country ski is located at the very front of the shoe and thus the corresponding pivot point lies in the foremost region of the sole, this does not significantly impede the movement.

However, this is different in skating shoes, since in these cases, two binding elements are arranged one behind the other, or this sport requires a more intense, and thus expansive, connection of the shoe to the ski. Therefore, in this case, the fulcrum of the turn of the foot is further back.

To remedy this defect is therefore provided according to the invention that flexible elements are provided both in the metartasal region of the hard shell and the shoe sole.

However, the essence of the invention is to be seen in the fact that is achieved by a running in the shoe sole clamping element when turning the foot, that the shoe sole is harder and thus the skier is given a significantly improved impression possibility.

The invention will be described in more detail below with reference to the figures shown.

In the Fig. 1 only the essential elements of the sports shoe according to the invention are shown. These are next to the shoe upper (1) and the sole part (2), the front Söhlenplateau (3) and the rear sole plate (4).

Between the two sole plateaus a tensioning means (5) is shown in the side view, all in the Fig. 2 shown possibilities of the design of the corresponding tie rods (6) are covered by this side view.

In the Fig. 1 is shown as an example of a sports shoe an alpine ski boot. The connecting elements for the respective sports equipment were not shown for the sake of clarity. As an insert come for the sports shoe according to the invention all sports in question which require a connection of a human foot with the respective sports equipment.

Since the adjustable flexibility of the sole part (2) requires a corresponding flexibility of the shoe upper (1), according to the invention in the Fig. 2 wing-shaped crush elements (7) shown. These crushing elements (7) consist of a very flexible, considerably softer material than that of the shoe upper (1). The configuration of the respective crumple elements (7) varies depending on their position on a curved, imaginary line which leads from the instep to the sole part (2). This described line represents the bending line that results in a bending of the shoe upper (1) for the imaginary case that the material of the shoe upper (1) consists of flexible material. Thus, the crumple elements (7) provide potential wrinkles for allowing the upper (1) to flex for the specific case that the material of the upper (1) consists of the hard material required for practical use.

To facilitate the problcmlose bending of the shoe upper, as in the Fig. 3 it can be seen, between the crumple elements (7) additional zones provided, which consist of a material composition which is slightly softer than the ordinary material of the shoe upper (1). These zones are designated by the term pressure element (8). For trouble-free introduction of force of a pressure element (8) in a crush element (7) is provided according to the invention, that in the direction of the Rists higher located, the crushing element (7) in the middle has a sharp bulge, the force line following, affected pressure element (8) deliberately weakens. This further measure ensures a bending of the sole element (2) corresponding convenient bending of the fixed shoe upper part (1).

The in the Fig. 2 indicated possibilities of arrangement of clamping means (5) correspond to different requirements in terms of desired adjustment of the clamping means (5) in different types of sports shoes. Your appropriate choice is left to the expert.

The possibilities of anchoring the relevant tension struts (6) are not aligned here only according to the expected forces but also after the choice of material for the respective sole plateau.

Not only can adjustment means be provided for the length of a particular tension strut on one side, but also on both sides. The simplest way to look for nuts that move on threaded pieces of the respective tension strut (6).

It is also possible in the middle of a certain tension strut (6) to provide one or more turnbuckles, which are designed in the form of a metallic cylinder whose inner bore on one side a left-hand thread and on the other side a right-hand thread that carry on a respective corresponding thread the remaining remainder of the relevant tension strut (6) is screwed. A rotation of such a turnbuckle thus leads to a contraction of the two anchored in the respective sole plateaus end pieces of the relevant tension strut (6). It is of course also possible to apply both measures of shortening a tension strut (6) at the same time on a tension strut (6). The outer shell of a turnbuckle may also be shaped according to the outer surface of a nut, so that it can be operated by means of a fork wrench.

The variant of merging two tension struts (6) in front of the anchoring point in the rear sole plateau, which is shown under point IV, can also be implemented using the example of variant III. Likewise, in the variant III shown the Fig. 2 in each case only one tension strut (6) may be present. This of course also applies to variant II.

In the example of variant II, a tension strut (6) can run parallel to the shoe longitudinal axis and the other, as in the example of the variant III obliquely.

In the Fig. 4 . 5 another embodiment of a sports shoe according to the invention is shown.

As usual, the hard shell (16) is attached to the shoe sole (11), which then merges into the shaft (17).

In the metatarsal area of the hard shell (16), ie the area where the foot is walking turns, and the shoe sole (11) a plurality of flexures (20) are arranged, which consist essentially of appropriately designed, the resulting creases corresponding areas of thinner flexible material than that of the hard shell (16).

However, it is essential that at least one channel runs in the shoe sole (11), in which a tensioning cable (13) can move along the shoe sole (11). This tensioning cable (13) is attached on the one hand to the tip of the shoe sole (11) on an abutment and on the other hand, after a deflection, connected to the lower end of the tensioning arm (18). This rope (13) thus runs along the shoe sole (11) and is at the end of the shoe sole (11) via the tensioning cable deflection (15) to the end of the tensioning arm (18) passed.

The clamping arm (18) is mounted on the one hand in the hard shell (16) and on the other hand in the uppermost region of the shoe. In the figure shown a pleasing design of the clamping arm (18) is drawn, but it can also be chosen a different shape. However, it should be ensured, in terms of a favorable lever arm, that the uppermost end of the lever, the clamping arm (18) in connection with the attachment of the Spannscils (13), as far as possible at the top of the calf attack.

The function of this lever arrangement, consisting of the tensioning cable (13), the tensioning cable holder (14), the tensioning cable deflection (15) and the tensioning arm (18), by lifting the heel and thus inevitably resulting rotation of the tensioning arm (18) against triggered in a clockwise direction.

Because by this rotation of the tensioning arm (18), the tensioning cable (13) is tightened in the direction of the arrow shown in the figure and thus the shoe sole (11) tensioned.

About the biasing lever (19), the bias of the tensioning cable (13) is adjusted and this bias can then be locked. For such a lock, there are various possibilities, for example the determination of a further, in the axis of rotation of the biasing lever (19) placed lock or a correspondingly shaped Huh mechanism.

The installation of the device according to the invention can be done easily and inexpensively by merely existing tool for cost to be changed cost.

The installation of the tensioning cable according to the invention will usually take place on the inside of the sports shoe, but it can also be adjusted by the installation of a further tensioning cable (13) on the outside of the sports shoe, the same or a different bias.

The effect of the clamping arm (18) can also be switched off by a so-called freewheeling element (23) a force transmission to the clamping arm (18), or a power transmission from this to the cable tension, is prevented. Appropriate measures for this purpose are known in the art.

The sports shoe according to the invention can, as in the Fig. 4 be shown opened for entry at the front or be designed as a so-called "rear beginner", as in the Fig. 5 can be seen in the rear view.

The tensioning arm (18) is divided in this case to allow the rear entry. By way of example, the use of two tensioning cables (13) with the respectively associated preloading element (19) is shown in this illustration.

Since the particular provided for the exercise of skating, tension of the shoe sole (11) primarily affects the respective inner edge of the ski, the tensioning cable (13) according to the invention is preferably installed in the left shoe right and left in the right shoe.

On the other hand, it is of course also possible to install two straps (13) in both shoes and to divide the hardening of the shoe sole (11) evenly or with different strains on both straps (13).

The heel lock (21) may in the simplest case have the form of a zipper or be buttoned.

An additional securing strap (22) provides a strain relief of the closure.

Instead of the tensioning device according to the invention, it is also possible to provide an anchoring of the tensioning cable (13) which can be directly adjusted at the rear region of the shoe sole (11). The front attachment of the tensioning cable (13) can also be done behind the metatarsal area, as in the Fig. 4 indicated by the double name for the tensioning cable holder (14).
