EP3197572B1 - Ski for combined use in climbing and downhill skiing - Google Patents

Description

The subject of the present invention is a combi-ski, with which both walking and climbing as well as gliding and driving on snow is possible, without assembly and disassembly of an additional device.

Various attempts have been made to develop and offer such skis, but all previously known products do not succeed in the market because they are too inefficient in one or the other of the above areas, too complicated in construction and handling, too heavy or too bulky.

For this reason, skis are still used for tours or hikes on snow and firn, which work perfectly in one area but have great disadvantages in the other, or require a special supplement to cover all areas satisfactorily.

For example, a cross-country ski is ideal for locomotion on flat or slightly inclined terrain, but not for steep climbs and descents.

The very popular ski touring is practically a full-fledged downhill ski, on the tread for the rise of a good adhering to the snow element, such as a fur strip, is attached, there are various types of skins and mounting options. The most common today are glue sticks used, which can be fixed relatively quickly on the tread. Nevertheless, they must be carried as separate utensils in the backpack, unpacked and assembled as needed and packed after dismantling again with the adhesive sides piled up. In the process, adhesive residues also adhere to the coating and these must be removed. These are all works that are uncomfortable, especially in windy and cold weather. The often used climbing wax has practically disappeared completely from the market, because its removal before departure was very tedious. He is only used on cross-country skis under certain conditions for competitions.

A very different snow sports equipment is the snowshoe, which has existed for centuries in the far north, and which in recent years has evolved from a tennis racket-like structure to a device composed of modern materials and has established a new sport worldwide: The snowshoeing.

Such snowshoes are ideal for hiking in all types of snow, but also for climbing over steep slopes. Driving and gliding with such snowshoes is not possible. There are already additional devices that should make it possible to glide and ride with snowshoes. However, mounting and removing such accessories is relatively cumbersome, especially when ascending and descending alternate again and again. In addition, the carrying of additional, relatively bulky material is not appreciated.

DE 20 2009 008211 shows a snowshoe, such snowshoes are designed only for walking. In DE 20 2009 008211 It is now proposed to provide a foldable plate on a snowshoe in the region of the foot hole, which is folded back to walk and has spikes on its underside. The plate makes up about 1/3 of the total length of the snowshoe. For slipping down, this plate can be folded forward by more than 180 °, and its now smooth bottom forms the snowshoe tip. The sliding down with such snowshoes is not comparable to the actual skiing and is also tedious.

JP H07 34875 shows a ski, which is divided over its length divided into two parts. The rear portion is pivotable about 180 ° from a position in which it forms a continuous sliding surface with the front portion, so that it rests on the front portion. The underside of the swung-around portion is then formed as an adhesion surface and should serve to ascend. The ski is in this state therefore only about half as long as in sliding position. In addition, the heel binding must be removed with forward folded back part. The adhesion surface extends only from the area following the ski tip to about the middle of the skier's boot. A walking is therefore less stable and exhausting, because you have to push so to speak, only a forward projecting ski.

From the WO 2012/095352 has become known Kombiski, which is suitable for both driving and gliding as well as for walking and climbing. It consists of a pair of skis with binding and the underside of each ski forms a sliding surface, which is divided into two sections, which form fitting sliding surfaces. A portion is hinged as a crossbar about a transverse axis of the combisisk by 180 ° to the other part of the area and can be secured in this folding position. The then underlying surface of the crossbar has an adhesion surface for walking and climbing certain nature, and the exposed by folding it down the area of the underside of the ski also forms an adhesion surface, with walking and climbing certain nature. A disadvantage of this construction, that the sliding surface is not continuous smoothly under the bond, but the transverse hinge groove is formed and the latter has a negative effect on the edge guide, especially when steep curves are driven because the edges are interrupted at this point.

The following additional prior art was known from the international search: the document US 2003/090086 A1 shows an actual ski, which has a so-called surface modifier 110 , that is a "surface modifier". This is designed as a turning plate, once with the rough side and once with the smooth side directed outwards attached to the ski body. For example, this insert measures approx. 81cm to 84cm in length and is 0.4cm thick, making it necessary for this ski, which is slightly longer overall, to be categorized as an effective ski and therefore compliant with all DIN standards for Is subject to ski fabrication and the binding design. Only skis with a maximum length of 59cm are not covered by this standard and therefore allow a much freer design. After this US 2003/090086 A1 this insert is inserted at the front with a blade in an associated slot on the ski body, and at the rear with a screw 128c attached to the ski body. In other variants, the insert is held along its entire length on one side by means of a spring and groove connection, as in FIG. 12B and held on the other side along its entire length by a metal clip 118b. It remains to be seen how, in detail, this metal clip 118b is to be loosened over the entire length and fastened again. US 2002/201777 A1 shows a snowshoe with a recess with central region in which a precisely fitting insert is pivotable about a transverse axis to the snowshoe. The AT 504 900 A4 shows a similar insert plate that can rotate around a transverse axis when walking. The EP 1 123 721 A1 Finally, shows a snowshoe with turning plate, which is mounted around a transverse axis schenkbar to him. To turn bearing blocks 8 must be removed here, which otherwise sit in recesses 9 on the base plate 1 of the snowshoe.

The aim of the present invention is, in view of this prior art, to further simplify such Kombiski, so that it can be easily, optionally and effortlessly switched from the function walking or climbing on the function of gliding and driving and vice versa. It is thought as a basis rather on the snowshoe than on a downhill or cross-country skis. The Kombiski according to the invention should therefore rather be a snowshoe with an integrated sliding part than a ski with integrated climbing aid, whereby, of course, a direct synthesis of these two solutions is also conceivable. In addition, this Kombiski should have improved sliding properties and better edge guidance, be foolproof in the operation and be inexpensive to produce.

According to the invention, this object is achieved by a combination disc which is suitable both for driving and gliding and for walking and climbing, consisting of a pair of binded skis, the underside of each ski being usable both as an adhesion surface and as a sliding surface, wherein the underside is equipped with a turning plate, which forms a sliding surface on one side, and on the opposite side has an adhesion surface, with for walking and rising certain nature, wherein the insert also rotated 180 ° about its longitudinal axis at the bottom the ski is fastened and in each position of use of the insert a continuous smooth underside of the Kombiskis is formed, and wherein the insert is fastened in both use positions on Kombiski by the underside of the Kombiskis in the front region forms a step of the height of the insert, extending itself extends across the bottom, and which is equalized after insertion of the insert with the underside of the insert to be used, and that at the front end of the insert halfway up the thickness of the insert a blade protrudes forward, and that this blade is inserted from behind into a slot in the step, so that the insert finds at this stage immovable in any direction support, this Kombiski is characterized in that the insert at its rear end, after insertion of the blade in the slot in the stage on Kombiski, in both positions of use by means of a mechanical buckle on Rear of the combis with this tail can be braced, including at the rear end of the insert a halfway up the thickness of the insert rearwardly projecting blade of the buckle with a bottom flat claw is gripped from behind and can be braced from below against the Kombiski tail , in which case the flat underside of the claw with the F pointing downwards surface of the insert is flush.

Fig. 1 shows a preferred embodiment of the Kombiskis according to this invention. The combination ski consists of two skis with shoe bindings, which are suitable for the ascent, by being switchable into a function, which allows the lifting of the heel. Such bindings have been known for many years, for example as plate bindings, in which a whole plate, together with the ski boot, is pivotally attached to the ski so that the heel can be raised and natural walking and climbing with the strapped skis is made possible. These bonds need not be described here. In FIG. 1 is a single Kombiski 1 seen from the side, with a molded tip to a blade 2, so that it is always lifted when driving in deep snow over the snow. The Kombiski 1 is shown here in the down position, without insert inserted. As a special feature, the underside of each combi-ice 1 forms a sliding surface 3. In the example shown, the sliding surface 3 is divided over the length of Kombiskis divided into two sections 3a, 3b. From the tip of the Kombiskis to under the expiring roundness of the tip of the ski, that is here in section 3a, the ski underside consists of the usual sliding surface. Then follows a step 4 and the Kombiski has afterwards on its underside in the partial area 3b a recess 8, for receiving a in FIG. 1 not shown insert. At the rear end of the combined ice bar, this has on its underside a triangular element 5, of the same height as the step 4. In the view shown, one sees from the side on a side surface of this triangular element 5, whose one tip with respect to the Kombiski shows in front. The side planks 6 of the ski protrude from the underlay floor initially steep and then bent outward upward and open into a peripheral edge 7, which is a few inches above the base floor.

The FIG. 2 shows the Kombiski FIG. 1 seen in a view from above with the sideways rising planks 6. It can be seen here the binding 10, which Overall, it is designed to be adjustable in the longitudinal direction on the Kombiski. It can therefore be fixed to ascend further forward and fixed to move down accordingly moved further back. The binding 10 can also be quickly switched from a fixed shoe end setting to a walking mode, allowing the shoe to swing up off the ski about a transverse axis near the toe of the shoe.

The FIG. 3 shows the Kombiski FIG. 1 seen in a view from below. It can be seen the peripheral edge 7 and front of the covering area 3a with the ski tip. On both sides of the edge 7 then extend the side planks 6. At the rear end of the front portion 3a of the bottom can be seen from the level 4, from which the underside of the combis is recessed relative to the portion 3a. This depression runs to the rear end of the Kombiskis and runs out there. Only at the very back, in the middle, a triangular element 5 is placed on the underside, which is of the same height as the step 4. In the inner region of the recess 8, this is open and gives the view of the inner structure of the ski, the In some transverse ribs 14 circular supports 15 are formed in which circular strong permanent magnets 9 are installed, all with the same polarity, for example, with the north pole outwardly visible.

The FIG. 4 shows the associated insert 11 in a view of its sliding surface 16, which consists of a conventional skating gliding. In the approximately middle region, the insert 1 is equipped on this slide lining side shown in the example shown four strong permanent magnets 9, which sit in corresponding brackets so that they are completely flush with the sliding coating. The polarity is chosen so that they are used opposite to the permanent magnets on the ski, so for example, with the south pole visible from the outside, when the north poles are visible on the ski from the outside. At the front end of the insert 11, here in the picture at the right end, there is a blade 12 which protrudes slightly beyond the half of the thickness of the insert 11 towards the front. It can be inserted at the onset of the insert 11 into the recess 8 on the ski from behind into a slot in the stage 4 on the ski and are the Turning plate 11 at this stage 4 an immovable in every direction. Rear, the insert 11 is placed with its V-shaped recess 13 on the triangular element 5 on the ski, so that it is mechanically secured back against lateral displacement. When inserting the insert 11, the permanent magnets 9 come to the insert 11 to lie on those on the ski and they adhere magnetically to each other, because the south poles meet the north pole. In a variant, the insert 11 may be equipped with permanent magnets 9, and the Kombiski 1 be equipped on its underside with a magnetizable layer to which the permanent magnets 9 adhere magnetically. Conversely, the underside of the combi-ice 1 can be equipped with permanent magnets 9, and the insert 11 can contain a magnetizable layer in its then laminate-type layer structure, to which the permanent magnets 9 adhere magnetically.

The FIG. 5 shows the insert 11 in a view seen from the side. As can be seen, the blade 12 is disposed at half the height of the insert thickness and projects beyond the insert 11 forward by a few millimeters. The edges on the edge of the insert - both at the edge of the sliding coating as well as at the edge of the peripheral adhesion surface - can be cost-effective designed as glass fiber edges, or for higher demands than ground steel edges.

The FIG. 6 shows the insert 11 in a view of the adhesion surface. All elements are identical to the illustration of the insert 11 after FIG. 4 , only the sliding coating in the shaded area is here replaced by an adhesion surface. This may consist in that the plate is covered with a laminated skin or hide such a climbing skin is laminated on it. The adhesion surface can also consist of an artificially created plate material, which forms a scaly, many small barbs protruding backwards. On this side of the insert 11, the permanent magnets 9 are installed directed in this case with the south pole to the outside. The reversing plate 11 is used to ascend in the same way as already described, namely pushed forward with the blade 12 in the slot in the stage 4, the rear with the recess 13 via the triangular-shaped element fifth slipped, and afterwards the permanent magnets 9 come to rest with their different polarity to each other and hold the insert 11 securely.

In FIG. 7 the ski 1 is shown from the front. Its blade 2 is realized by a curvature of the ski tip upwards. In contrast to conventional skis, which look like the lower part of the drawing from the front, this ski does not have a flat cross-section, but rather is shaped in the manner of a boat, so that a double deck is formed. The plank-like elevations 6 forms with their edge regions 7 a raised deck, so that the Kombiski here has a double deck. Like a boat plowing through the water, so does this ski plow through the deep snow, so to speak. It creates more buoyancy thanks to its boat-like shape and width, and with its side edges 17 on hard snow it still gives it a sharp edge grip like a conventional ski. The lower deck with its sliding surface 16 acts in deep snow together with the upper deck and its planks 6 and their edges 7. In soft deep snow, a greater buoyancy is generated, which carries the Kombiski, while the edges 7 of the upper deck in soft or deep snow in addition to the Edges 12 act as soft snow edges. On hard snow or on piste-like snow is driven only on the narrow lower deck with its sliding surface 16, and then act their edges 17 as the only edges and the edge is done with ease. This Kombiski is therefore not only a Kombiski in terms of combination options for ascent and descent, but he also offers an optimized and ideal combination for the descent in deep snow as well as hard snow.

In FIG. 8 the cross-section of the ski 1 is shown. In the example shown, it consists of a continuous plastic mold 18 which terminates at the sides in the elevations or planks 6, which forms with their edges 7, the elevated deck for deep snow driving, the edges 7 act as soft snow edges. In this basic form 18, a support plate 19 is installed, which is fixedly connected to the base mold 18, and on which the binding is mounted longitudinally displaceable. At the bottom of the basic shape 18, the insert 11 closes with its sliding lining 16. The edge of a conventional wide touring skis on hard surface as it is often necessary to tours both while climbing and while driving to secure hold to find, often laboriously. Here are the lateral glass fiber or steel edges 17 along the lateral lower longitudinal edges of the ski to wear. They give him the necessary edge grip. Based on test experience, it has been found that this Kombiski with its double-deck principle makes it much easier to edge up, even if you tend to wear softer shoes, making traversing hard, smooth fields safer. Nevertheless, this Kombiski offers excellent deep snow driving characteristics. The double-deck principle, which provides a wide wing in soft snow where it is needed, and a narrow climbing or sliding surface on hard snow, provides an ideal combination for changing snow conditions and operations.

FIG. 9 shows this Kombiski in a perspective view and underneath the associated insert 11. With arrows is indicated that this is intended for installation in the underside of the Kombiskis. The binding 10 is displaceable on the visible rails 25 in the longitudinal direction of the ski 1 in the example shown here. The binding 10 has at the front a headband 20 for the front sole edge of the ski boot, and at the rear a retaining bracket 21 for the rear sole edge at the heel of the ski boot. The main body 22 of the binding 10 is articulated in the front region via the pivot axis 23 on the ski, that is on a further, belonging to the binding displacement element 24 which is longitudinally displaceable in different adjustment positions on the ski 1 fixable. Serves here the central rail 25 with interruptions 26, in which a spring-loaded bracket 27 can be latched.

In FIG. 10 is another embodiment of the Kombiskis shown in a perspective view obliquely from behind, with another, purely mechanical fastening system for the insert 11. For this purpose, the Kombiski is equipped at its rear with a clamping buckle 28, with which the rear end of the insert 11 is tensioned against the underside of the Kombiskis 1. This clamping buckle 28 forms at its rear end a downwardly projecting claw and the clamping buckle 28 is pivotable about two axes on the upper side of the Kombiskis 1, as will be disclosed in more detail. In addition, the Kombiski 1 is equipped with a shoe stabilizer 29. This shoe stabilizer consists of a shaft 30, which is in the applied Kombiski 1, so if the shoes are in the binding 10, along the rear of the shoe shaft of the skier snuggle shoes, so slightly inclined forward. This inclination is defined and fixed by the projections 31, which are integrally formed on both sides of the shaft 30 by these projections 31 are fastened to the binding 10 and thus allow tilting of the shaft 30 neither backward nor forward. Above extend from the shaft 30, two arms 32 forward and upward, with at its front end a respective buckle 33 for holding straps. It is entered with the shoes in the binding 10 by looking from the front to the back with the shoes to the shafts 30 of the shoe stabilizers 30 abutting. Thereafter, the two arms 32 are wrapped around the upper end of the shoe upper and the two front ends are clamped by means of straps on the buckles 33 with each other, whereby the shoes are always tied with their shanks to the shoe stabilizers 29 and thus the inclination of the shoe shafts only in one may vary in size. Below the projections 31 are brackets 34 are arranged on which also straps are fastened, and these straps are wrapped around the shoestring and braced together, resulting in a snug fit of the shoes in the holder 10. In FIG. 11 this Kombiski 1 is shown in a view from the side. You can see the back of the open buckle 28.

In FIG. 12 This Kombiski 1 is shown from above. It can be seen the bond 10 with their components and at its rear end the shoe stabilizer 29 with its shaft 30 and the two arms 32. At the rear of the Kombiskis the tension buckle 28 is visible in the area A, here in pivoted state. This area A is in FIG. 13 shown enlarged. One recognizes the Kombiski 1 with its side planks 6 and at its rear end this tension buckle 28 in the swung-open state, so you can see its forwardly facing sides 35, 36 and the obliquely extending side surfaces 37.

The FIG. 14 shows the open rear fuse of the insert 11 in a section along the line BB in FIG. 13 , This tension buckle 28 for the Rear securing the insert 11 consists of two components, a base piece 38 and a clamping part 39. On the base piece 38 is transverse to this axis 40, on which a pivot piece 45 is pivotally mounted. At this pivot piece 45, a pivot member 42 is fixed, which is hinged at its other end pivotally about the axis 41 on the clamping part 39. This forms a double joint. The clamping part 39 forms a claw 43 at its rear end. Below at Kombiski 1 can be seen here the insert 11 with its two pads top and bottom. One covering forms the adhesion surface, the other covering forms the sliding surface. At the rear end, the insert 11 here forms a blade 44, in a manner similar to the previously described blade 12 at the front end of the insert 11. The combination die 1 at its rear end forms a downwardly projecting step 46, opposite the recess 8, onto which the blade 44 fits positively. Is pushed from the position shown, ie when inserted and secured by means of the blade 12 turntable 11, the claw 43 of the clamping member 39 on the underside of the blade 44 and the clamping part 39 afterwards pivoted to the double joint down, so in the picture clockwise down pivoted, so the claw 43 biases the blade 44 forward and finally also upwards, so that the blade 44 is pressed and stretched to the level 46 fed.

How to get in FIG. 15 detects, the axis 40 is higher than the base 41 on the base piece 38 in the illustrated here Abschwenkens the clamping member 39 as the axis 41 on the clamping part 39 itself. This causes a securing of the tensioned state of the clamping member 39, due to the geometry of the double joint. is to overcome a vertex during the tensioning path, and beyond this vertex, the clamping member 39 is pressed down on the surface of the Kombiskis. How to get in FIG. 15 sees, in this position, the claw 43 fed on the blade 44 and presses it permanently against the step 46 at the bottom of the bottom of the combi-ice 1. The bottom of the claw 43 is flat and runs in the clawed and strained state as in FIG. 15 shown flush with the sliding surface of the insert 11th

The FIG. 16 finally shows the Kombi with open tension buckle 39 and the shoe stabilizer 29 in a view from behind. The tension buckle 39 is swung up, you can see therefore their top. In addition, you can see the shaft 30 of the shoe stabilizer 29 and the two arms 32 at the upper end of the shaft 30, with the shells 33 at the front end of the arms 32. Bottom of the shoe stabilizer 29 can be seen the bracket 34 for securing tension straps. In the FIG. 17 In addition, the same view is shown, but with pivoted down and thus tensioned clamping jaw 39 of the rear fuse.

This Kombiski has a continuous, step and gap-free sliding and climbing surface, whereby the climbing and sliding is optimized. The replacement of the insert 11 can be done easily, quickly and without tools, which is very important, because snowshoes or users of such Kombiskis sometimes cross half or even quite apere areas in mountain slopes. Also, they sometimes move over snow and firn fields, which can be interspersed with sand or pebbles. In particular, the sliding surface can be scratched on such a surface or even seriously damaged. In such a case, in the present system, simply replace the insert and it is therefore not necessary to replace the whole Kombiski. It can also be offered to this Kombiski 1 several different inserts 11, with different sliding and or Adhäsionsflächen, or, for example, a cheaper version with glass fiber edges and a professional version with steel edges. Snow, ice and dirt residues on this insert 11 can be easily removed at any point, which is less well done in a hinge construction. Of particular importance is the two-part design of the Kombiskis from the ski on the one hand and the insert 11 on the other hand, which simplifies production and makes cheaper, because it eliminates the work for mounting a hinged sliding or adhesive plate. The robustly formed turning plate 11 makes it possible to dimension the one-piece main part of the ski 1 thinner than in a hinge version according to WO2012 / 095352 , which further reduces the manufacturing costs. The function of the insert 11 and its handling is very simple and therefore foolproof and requires no great explanation and instruction. Overall, this Kombiski is a compact, holistically thought-out and maximally reduced to the essentials product with still improved function, and which is even easier and therefore less expensive to produce.
