Description

Sports shoe

The invention relates to a sports shoe, especially for skiing and snowboarding.

According to the modern technique of skiing but also of snowboarding, a direct connection between foot and sports equipment is necessary. In particular, this is achieved with sports shoes in a shell construction. In contrast to the requirements for the shoe when skiing, it is essential in snowboarding to achieve an adjustable damping of the forward inclination of the shaft, with m other concerns dominating the common properties.

Experience has shown, however, that the use of the sports shoe for skiing and snowboarding is only a maximum of 30-40% of the total usage time. During the remaining time, the wearer uses the shoe in particular to walk. In the known shoes, however, this is usually rather tedious, or the shoes used do not meet the strict standards prescribed for skiing.

From US Pat. No. 4,920,665 a ski shoe with a movable front part is known which remains in the binding with the sole, whereby the shoe should be suitable both for alpine skiing and for walking with skis.

However, snow and ice collect in the resulting gap, which in particular can result in the mechanical system being shut down. Furthermore, there is hardly any need for such shoes for walking with skis, since this area is already covered by so-called touring shoes and touring bindings.

EP-A3 234 908 shows a ski boot which is movable in the front part by means of a bellows and can also be locked without, however, providing the boot with absolute stability in the safety binding.

AT-PS 376 555 also shows a sports shoe that can move in the front part, but which, likewise, cannot meet the safety standards necessary for skiing or snowboarding with regard to the overall rigidity of the shoe. The object of the invention is to avoid the above-mentioned caching parts and to provide a sports shoe which fulfills both the overall stiffness required by the standards and a mobility of the shaft and front part, in order to enable problem-free walking with this shoe.

The invention solves the problem in that a sports shoe consisting of a lower part comprising two mutually movable sections and a fore-end and a buttstock which are connected by a joint is characterized in that the movable sections of the lower part Can be fixed via an actuating device that in the region of the lower part adjoining the buttstock there is an actuating element arranged movably in the lower part, and that the actuating element with the buttstock in Ver is binding and is connected to the actuating device, such that a simultaneous fixation or release of both the shaft and the lower part takes place when the actuating element or the actuating device is actuated.

The actuating element, which is movable in the rear shaft and protrudes therefrom, comes into contact with the binding upon entry into the binding, as a result of which the latter is moved and, via the connection with the actuating device, also moves it and causes the entire shoe to be blocked. Conversely, when exiting the binding, the locking function of the actuating element can also be released by actuating the actuating device arranged on the front shoe, whereby both the front shoe and the shaft move and an easy walking is ensured.

The invention further solves the problem in that a sports shoe consisting of a lower shoe, a forearm and a buttstock, which are connected via a joint, is characterized in that the buttstock is provided with a spring device such that the lower shoe is positioned below the Actuating element arranged for the spring device, preferably a tailgate, for the spring device, and that the spring device can be connected to the tailgate via a receiving device designed as a receiving bracket for automatic locking of the shaft when the tailgate is engaged. In particular when using the shoe for snowboarding, the hardness of the damping of the forward inclination of the shaft can be selected through this design.

The invention further achieves the object in that a sports shoe with a lower part consisting of two mutually movable parts and a shaft is characterized in that one of the movable parts is provided with an actuating device designed as an adjusting element, that the lower part is in its rear In the area below the shaft with an externally operable tailgate, the tailgate is connected to the adjusting element via a connecting linkage or a Bowden cable, and the tailgate is connected to at least one spring arranged in the sole area of the shoe.

This design enables the tailgate to be actuated and fixed easily, with forced switching taking place by entering the binding.

Further advantageous developments of the invention are disclosed in subclaims 5 to 30.

The invention will now be described in the following using an exemplary embodiment with the aid of the attached drawings.

1 shows the sports shoe in the stable driving position in a perspective view; 2 shows the sports shoe in a longitudinal section with the damping of the shaft switched off; 3 shows the sports shoe in a longitudinal section in a stable driving position; 4 shows the sports shoe in a longitudinal section in a fully movable position; 5a shows the front part of the sports shoe according to the invention with the actuating device in the blocking direction; 5b shows the front part according to FIG. 5a in free position; 5c shows an exploded view of the sports shoe; FIG. 6a shows the spring device in the assembled state in the buttstock in a perspective view; 6b the spring device in an exploded view; 6c shows a further embodiment of the spring device; 7a shows the spring device in the buttstock, relaxed in the driving position, in a schematic representation; 7b the spring device relaxes in free position with the damping switched off; 8a, b, c the spring device in the buttstock in the tensioned state in various positions; and FIG. 9 shows an embodiment of the sports shoe for mountain biking according to the invention. 1 shows a sports shoe for skiing and snowboarding, manufactured in a shell construction, with a lower part 1 divided into two sections 1 a, 1 b, which in the front area 1 b at the level of the forefoot joint extends transversely to the longitudinal axis, starting from the sole has upwards to slot 25 opening at an angle of approximately 25 °, a fore-end 2 and a rear-end 3, these parts being pivotally connected to an axle bolt 4.

The fore-end 2 and the butt-end 3 are closed by a conventional tensioning system 23. The inner shoe 5 is pushed into this shell. The slot 25 is preferably filled with elastic material.

An actuating device 9 is arranged in section la of lower part 1, with the aid of which sections la, lb can be kept movable or locked relative to one another.

For this purpose, the actuating device, as shown in FIG. 5c, is designed, for example, as a rotary handle 28 which pierces through an opening in the shoe and is connected to a disk 29 on the inside of the shoe. The front section 1b of the lower part is provided on its inside with a wall 26 which extends over the area provided with elastic material into section la and is provided in this area with a web 27 which extends into a recess 36 of the shoe can snap into place. The rotary handle 28 is provided on its side inclined towards the shoe with an elevation 30 which engages with the web 27. By turning the rotary handle, the web is either pressed out of the recess 36, as a result of which the two sections 1a, 1b can be moved relative to one another. If the twist grip is turned in the opposite direction, through the interaction of the elevation 30 with the web 27, the latter can be pressed into the recess 36, as a result of which the two sections 1a, 1b are locked and the foot part of the shoe is again used for skiing - or snowboarding has the necessary stiffness. The elevation 30 moves in a suitable recess in the shoe. The grip part designed as a twist grip can also be designed as a lever, for example. The grip part 28 is advantageously detachably connected to the disk 29 by means of a screw. The actuating device 9 described above is connected to the heel area of the shoe via a connection formed, for example, as a linkage 8 or Bowden cable, wherein the linkage can also be actuated hydraulically or pneumatically.

In this area there is an actuating element, preferably designed as a tailgate 6, which is movably fastened in the shoe. The tailgate 6 can be guided out of the shoe via an opening 31 and is arranged in the area directly above the sole in the rear middle area of the lower shoe, whereby in the closed state, that is, when it is not out of the shoe, is flush with the outer surface of the shoe. The tailgate 6 is in the release of the shoe, that is, when it is movable, out of the shoe. When stepping into a ski binding, this tailgate is pressed into the shoe and, actuated by the tension spring 7, snaps into a recess 37 in the sole area.

The tailgate is advantageously connected to the actuating device 9 via the linkage 8.

If, as described above, this tailgate is triggered by a safety binding and brought into its rest position by the tension spring 7, the actuating device, which is also in an open state, is rotated through the linkage 8 by approximately 65 ° in If a lever is used, it is displaced by a certain distance, and the wall 25 arranged in the toe part of the lower part is displaced such that the web 27 is pressed into the recess 36 and locked via the elevation 30 of the actuating device. As a result, the sole of the lower part 1 is completely stable as required.

In the exemplary embodiment, the actuating device is designed as a rotary handle and is arranged on one side of the front shoe. Of course, such a device can be arranged on both sides of the front shoe for an even greater stability of the shoe. The power transmission between the two devices takes place via a bracket 19. However, this effect can also be achieved by doubling the connecting rods or Bowden cables and the tension spring 7. An arrangement in the middle of the shoe also seems conceivable and practical. Simultaneously with the latching of the tailgate 6, an elastic lug 32 connected to it on its upper part snaps into the mounting bracket 10 arranged on the rear stock 3 or into a slot 33 of the same.

The mounting bracket 10 is part of a spring device 22 which is arranged on or inserted into the buttstock and which serves to tilt the shaft forward.

When the nose 32 is snapped into the slot 33, the shaft can only be tilted forward via the spring element 22. The position for skiing and snowboarding is established.

If the sports shoe is then to be used for walking, the turning handle 28 only needs to be turned again by about 65 ° to the open position (denoted in FIG. 5b). However, this angle essentially depends on the transmission ratio and can vary depending on the articulation of the arrangement. The tailgate 6 is thus pushed back out of the shoe via the connecting rod 8 or a Bowden cable, the tension spring 7 is tensioned and engages in two knobs arranged in the lower region of the tailgate in the lower part 1. The resilient nose 27 is pulled out of the connection with the mounting bracket 10. The actuating device 9 pushes the web 27 out of the recess 36 and, by means of the elevation 30, prevents the web from engaging.

This makes the sports shoe fully flexible and suitable for walking, running or climbing stairs.

The design of the spring device 22 is shown in particular in FIGS. 6a, b.

According to the exploded view shown in FIG. 6b, the spring device arranged in the rear stock 3 comprises a central spring 11, an inner pair of springs 12, an inner bracket 13, an outer pair of springs 14, an outer bracket 15, and the mounting bracket 10, on which the springs are arranged in their lower area. The upper end of the middle spring 11 is connected to the butt stock 3, the inner and outer pair of springs to the corresponding brackets 13, 15. In order to tension the springs, ie to achieve different hardness settings for damping the shaft, there is an adjustment in the butt stock 3 arranged lever 16 which passes through the spring device 22 with an axis 34 on which cams 35 are arranged for actuating the springs. This setting of different hardnesses is particularly interesting when the sports shoe is used for snowboarding.

In the arrangement of the springs described above, the inner pair of springs 12 is initially loosely suspended in the inner bracket 13 at its upper region. If the adjusting lever 16, which is rotatably mounted in the butt stock, is now brought into a position shown in FIG. 8b, the two cams 35, preferably hook eccentrics, arranged on the axis 34 block the inner bracket 13, the inner pair of springs 12 thus additionally being used Middle spring 11 is under tension. The outer pair of springs 14 is fixed in its upper region in the outer bracket 15, which in this position slides past the central spring 11 and the inner pair of springs 12. If the adjusting lever 16 is switched to a position according to FIG. 8c, two further cams arranged on the axis, preferably designed as hook eccentrics, block the outer bracket 15, which in turn now also blocks the inner bracket 13. As a result, both the middle spring 11, the inner pair of springs 12 and the outer pair of springs 14 are under tension.

Different tensions of the shaft can thus be achieved by switching the adjusting lever. At the same time, this means different hardnesses of damping the forward inclination of the shaft 2, 3.

The springs described above can also be replaced by rubber bands, hydraulic or pneumatic elements.

The two sections la, lb of the lower part can also be pivoted via a pin 20. It is also possible to inject a bearing on the two parts at the same time as the manufacturing process.

The spring device 22 can also consist of only one pair of springs 17, which is fastened at its lower end in the mounting bracket 10 and at its upper end in the butt stock 3. This variant is only suitable for skiing. A complete relief of the shaft is shown in FIG. For this purpose, a lever 18 which causes this state is arranged on the buttstock 3 at its lower end and can be switched on and off manually.

In a variant of the sports shoe which is only suitable for snowboarding, the tailgate 6 is modified such that it does not come out of the sports shoe, but is only inside the shell. The rotation of the actuating device 9 can be carried out by a switching lever 21 arranged in the pivot point of the shaft 2, 3 (FIG. 9).
