Definitions

  • 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.
  • 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.
  • 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.
  • an alpine ski boot with a pliable shaft is known in which the design of the sole allows the foot to flex while walking.
  • 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.
  • 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.
  • ski shoe known from WO 02/094047 A1.
  • sole which is flexible in the metatarsal region, as already described in US Pat WO 01/35780 A1 are described.
  • different solutions are pointed out in this document for the problem of the flexible shell part to be designed in the forefoot area.
  • various new shapes, constructions and design studies of the liner are presented.
  • 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.
  • 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.
  • the middle area 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 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.
  • the sole of the prior art cross-country ski shoes is usually quite inflexible.
  • 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.
  • 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.
  • 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).
  • 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.
  • 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.
  • 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.
  • a certain 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.
  • a tension strut (6) can run parallel to the shoe longitudinal axis and the other, as in the example of the variant III obliquely.
  • FIG. 4 In the Fig. 4 . 5 another embodiment of a sports shoe according to the invention is shown.
  • the hard shell (16) is attached to the shoe sole (11), which then merges into the shaft (17).
  • 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).
  • 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.
  • 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.
  • the bias of the tensioning cable (13) is adjusted and this bias can then be locked.
  • 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.
  • 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.
  • the use of two tensioning cables (13) with the respectively associated preloading element (19) is shown in this illustration.
  • the tensioning cable (13) is preferably installed in the left shoe right and left in the right shoe.
  • 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.
  • tensioning device 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).
