    The present invention relates to a long-roof ski, specially intended for so-called classical akstil but also usable in so-called skating, skating with skates.
    When skiing, it is important to be able to avoid having a backlash, and this regardless of the style. When sledding with classic axillary, the underside of the ski is selected or fitted with another mechanical device, e.g. rear-facing notches in the lining on the underside of the side, which notches are intended to grip the pair of skis and prevent slipping backwards. Mechanical devices have always had the disadvantage that they pre-assemble the slide forward. Grazing must often be repeated to obtain the desired effect, and also adapted to the ski liner. When skating, ambush is largely avoided by sledding with skates in combination with whey. With few exceptions, the best imaginable glide forward is desired. Almost all skiers experience dl and dl problems with either the skis being slippery or they are smaller slippery but on the other hand have a slippery slope.
    To remedy the problems with ambush or poor gliding, the skis are chosen. However, grazing is a cumbersome procedure that takes time and must be performed in a professional manner to achieve the best results. In addition, the grazing must be carried out differently from one time to another depending on snow conditions and temperature. In addition, in one and the same act, areas with different temperatures or snow conditions can be passed, which leads to the grazing not obtaining the intended best result.
    Embankments, or mechanical devices, are used for gripping, fastening. If the parts where fixed beams are applied lie H: DOCWORK1130228 Ans5krEngstext.docx, 2013-02-28130001EN 2 against the ski pair, the disadvantage arises with a slider. To solve this problem, cross-country skis have a bend up, span, at the center of the ski, and the natural weight of the ski is used so that this part, when the field is loaded on this section, is pressed down against the ski pair. The mooring is laid along a stretch of approx. 0.5 m at the said bend at the middle of the ski. The principle is that the field with its weight distributed on the skis should not press down the undersides of the skis against the pair of skis at the bucket, but there should still be a minimal arch where the embankment is located. The wall is thus, ideally, just above the snow, which allows maximum gliding forward. When the weight distribution is different, the arch of one ski will disappear and the embankment will thus slow down somewhat against the snow. When sliding downhill, it is not possible to constantly keep an exactly even balance between the skis so that the arch is perfect between the skis, which is why one ski in practice will slow down somewhat. When kicking off for towing in the future, the weight of the field is redistributed so that one ski takes up the entire weight of the field, which, however, in principle only gives 50% grip. The ski team hails up 50% of the field's weight. Additional grip is obtained, however, by utilizing the field's mass inertia, extra trampling before the field's body has time to be moved upwards. With today's solutions, it is not possible to achieve the complete grip you want, ie. to be able to use the full kicking force of the legs without slipping.
    A complete prevention of backlog can be obtained if the underside of the ski in its entire length is provided with so-called stighudar. If so, however, the slide forward will be largely non-existent. Putting on skins only on the part where the ski is rolled is also not good, as this part of the ski when sliding forward to and from lies against the snow and brakes, and also entails a risk of falling forward when driving downhill.
    H: JJOCWORK 130228 Ans5krEngstext.docx, 2013-02-28130001EN 3 Today's long-distance skiing skis must be adapted to the varying weights of different skiers, and to some extent also to their style. This per an unadulterated start range and thus also more expensive skis.
    The problem to be solved for the present invention is thus to provide a ski which is designed so that under normal load on the field it has a residual span. Even if the field rests with all its weight on a ski, but which when redistributing the load to only the driver's front pedal pad is designed to be applied to the underlying substrate, ie. snon.
    U.S. Patent No. 5,427,400 discloses a longitudinal ski which includes a recess in the core of the ski under the barrel of the field to assist in depressing the center section of the ski when the ski is loaded by the field actively pushing the foot down to engage the ski.
    What is not solved by this previously known design of a ski is to be able to achieve a predetermined load point at which the ski is pressed down against the ground.
    The object of the present invention is therefore to solve this problem.
    The above object of the invention is achieved with a ski according to the invention in that the ski at the place of the span comprises a resilient device which extends sip in the longitudinal direction of the ski, and where there is an empty space between the upper side of the ski and the underside of the resilient device. and ddr the resilient device Or designed to collapse at a certain applied load upwards, so that at the farmer's load on the foot the spring- H: DOCWORK1130228 Ans5krEngstext.docx, 2013-02-28130001SE 4 underside is pressed down against a surface under the ski.
    According to a particularly preferred embodiment of the invention, the sheath at the location of the span is split in its direction in that the sheath comprises a rigid upper part and a folding lower part, the folding part being arranged to separate from the rigid upper part w at the collapse of the resilient device. pressed down so that its underside is pressed down against the surface under the ski.
    According to a further preferred embodiment, the resilient device is provided on its underside with a rigid member extending through or passing and displaceable in relation to the rigid upper part of the ski and connected to the collapsing lower part.
    According to another preferred embodiment of the invention, the ski is on its underside below the location of the field barrel, provided with a rear anti-slip device.
    The invention will now be described in more detail in the form of an exemplary embodiment, illustrated in the accompanying non-limiting drawings, in which Fig. 1 shows a side view of a central part of a long-roofed ski according to the invention showing the field barrel without load for kick-off, Fig. 2 a side view Fig. 3 shows an exploded view of the middle section of the ski according to the invention with the parts essential for the invention separated from each other. Fig. 4 shows a cross section through the ski at AA in Fig. 3, and Fig. Shows a cross section through the ski at BB in Fig. 3.
    H: DOCWORK1130228 Ans5krEngstext.docx, 2013-02-28130001EN A cross-country ski 1 according to the invention is in its front and rear part designed as a completely conventional cross-country ski, and can thus have the different designs that are known, such as e.g. consisting of different kanda materials.
    The ski 1 thus comprises a front section 2 with the tip of the ski, a middle section 3 in which the binding of the ski is arranged, and a rear section 4, cidr the front and rear section seamlessly merges in the middle section 3. The essential thing for the invention is the middle section 3 of the ski. On the edge, Or the middle section 3 sat thickest in the middle, and becomes thinner towards its spirits, towards the front 2 and rear 4 sections. The ski Or at the location of the buckle 5, i.e. in the middle section 3, provided with a resilient device 6 which stretches sip in the longitudinal direction of the ski 1, and where there is closest a bond 7 on the ski there is an empty space 8 between the underside of the resilient device 6 and the ski top.
    The resilient device 6 may be of a fiber-reinforced plastic material, in particular a carbon-fiber-reinforced plastic material or a strip of steel, preferably stainless steel. The resilient device 6 Or in rest position either straight or provided with a slight curvature stretching sip in the longitudinal direction of the ski, ie. said that the resilient device 6 in the middle of the ski 1, seen in cross section (as shown in Fig. 5), lies higher than the sides of the ski. The ski is designed in such a way, with regard to its thickness and its material properties, that the span of the ski when the field is normally standing on the ski, even if the field only stands on one ski, can only support the weight of the field. The resilient device 6 is designed so, with respect to its thickness and its material properties, that when the plow loads the resilient device 6 by pressing with its body weight on the front pad of the foot 9, the resilient device 6 will be knocked and the middle section of the ski in its entirety pressed H : DOCWORK1130228 Ans5krEngstext.docx, 2013-02-28130001EN 6 down to the ground, the underlying pair of skis 10, as shown in Fig. 2. The resilient device 6 has clamed properties similar to a steel carpet band, which on a certain extraction is knocked off its own weight.
    According to the particularly preferred embodiment of the longitudinal roofing sheath according to the invention, as shown in the drawing figures, the middle section 3 is split from the side so that the middle section 3 consists of a folding lower part 11 and a rigid upper part 12. The folding lower part 11 is in its front and rear part integrated in the ski but can be caused to be separated from the rigid upper part 12 when the middle part is loaded so that the underside of the ski is brought into contact with the underlying pair of skis 10.
    The separation of the failing lower part 11 from the rigid upper part 12 can be achieved by inserting a slip foil in the manufacture of the ski between the layers which form the failing lower part and the rigid lower part.
    The resilient device 6 is located in the middle of the door where the user of the ski, the skier, has his front part of the foot 9 when skiing, and when the skier loads the front part of the foot 9, the resilient device 6 is arranged to collapse so that a part of the is pressed down into the empty space 8 between the resilient device 6 and the upper side of the ski 1. This increases the load on the middle section 3 so that the underside of the ski is pressed down against the base 10, ie. the ski couple.
    The collapsing lower part 11 of the ski 1 Or with a rigid member 13 connected to the resilient device 6 mounted on the upper side of the ski, and where the rigid member 13 Or is arranged to pass freely through the rigid upper part 12 of the ski. tap of tra. or H: DOCWORK1130228 Ans5krEngstext.docx, 2013-02-28130001EN 7 plastic that passes through a hall in the rigid Upper part 12 has the ski. When the resilient member 6 collapses at a certain applied load from above, the rigid member 13 will be displaced downwards through the tail in the rigid upper part 12 of the sheath and press down the failing lower part 11 so that it is separated from the rigid upper part 12 and pressed against the base 10. , i.e. the ski couple. Alternatively, the rigid member may be designed to pass the rigid upper part 12 of the ski outside its edges.
    The sloping lower part 11 of the middle section of the ski has a length of 300 to 750 mm, and a thickness of 2 - 10 mm.
    The resilient device 6 is, in order to obtain a suitable height of movement on the sagging lower part of the ski with a distance at the front and with a distance from about the middle and rear, placed at a suitable height above the upper edge of the ski, preferably 2 - 12 mm, which constitutes the empty space 8 between the resilient device and the ski 1. At the end of the empty space 8 a pivot point 14 is formed. This pivot point 14 can be formed by a plate 15 Or arranged on the upper side of the ski 1, the front outer edge of the plate 15 constituting the pivot point. Alternatively, the pivot point 14 may be formed by the fact that the ski in its outer part is provided with a recess, which in that case also forms the empty space 8.
    Just before the pivot point 14 of the resilient device 6 and to the rear edge of the resilient device 6, the resilient device is slightly stiffened, so that the rear part of the resilient device 6 is pressed upwards when the front part is pressed down into the empty space 8, and thereby the haul of the field is forced to be lifted. This stiffening 16 may be formed on the upper side of the resilient device, and be arranged to function as a guide 16 for the skier's ski boot.
    H: DOCWORK1130228 Ans5krEngstext.docx, 2013-02-28130001EN 8 Alternatively, a stiffener may be provided under the resilient device.
    The location of the pivot point 15 should be the side that the front part of an acre barrel 9, the pedal pad has Akaren, is located in front of the pivot point 14. When the acreage loads the foot 9, depresses the pedal pad and "knocks" the resilient device 6, the resilient device comes Fig. 6 thereby being rotated about the transverse pivot point 14 resulting in the front part of the resilient device 6 in front of the pivot point 14 being pressed down, while the stiffening 16 has the resilient device 6, behind the pivot point 14 lifted up, Fig. 2.
    Optionally, the pivot point 15 may be slightly displaceable in the longitudinal direction relative to the empty space 8 in order to provide an opportunity for adapting the "kinking" force which needs to be applied in order for the resilient device 6 to be "knocked". This can be achieved in particular at the pivot point 14 Or formed by the front edge of a plate 15 fixed on the upper side of the ski, in the plate 15 di Or arranged slidably in the longitudinal direction of the ski 1.
    According to a preferred design, the resilient device above or below itself may be provided with one or more resilient blades to create different forces required for "knocking".
    It is also preferred that the resilient device be of carbon fiber or of stainless steel, preferably stainless steel of the spring, or provided that other materials which can be phased to collapse at a given load, and then after the load has ceased to return to their original shape, can be used.
    H: DOCWORK1130228 Ans5krEngstext.docx, 2013-02-28130001EN 9 The resilient device 6 can also be designed in different versions with different stiffness, in order to take into account the weight and / or force of the field when kicking the field. The resilient device can also suitably be integrated with the binding 7 of the ski, so that they form a common unit which is fixed in the ski 1.
    In order to further improve the grip shape when kicked off with a sheath 1 according to the invention, it is suitably also on its underside, under at least a part of the middle section 3, provided with a friction-increasing material or a friction-increasing coating, e.g. and s.k. stighud.
    Due to the fact that the ski 1 is split and has a folding underside 11 and rigid upper side 12 according to the invention, it is guaranteed that mainly the underside of the middle section 3 of the ski 1 comes into contact with the base, the pair of skis, when the field loads the ski so that the resilient device 6 (Shown in Fig. 2). Because the ski Or is provided with the edging device 6 as a phase to collapse Or it normally, when the field is sued does not load the 9 for kick-off, stiffer than a normal ski, which means that the underside of the ski at the middle section 3 does not come into contact with the base, the ski pair , and thus does not impede the farmer's travel forward at e.g. sliding in a downhill slope, and thus not in any way slows down the field or slows the skier SO that it falls. collapses the feather motif in one foot H: DOCWORK1130228 Ans5krEngstext.docx, 2013-02-28130001EN
