Definitions

  • the present invention relates to a climbing aid for attachment to a waisted ski, in particular to a touring ski.
  • the crampons are conventionally placed on the top of the ski between the ski boot and the ski (see, for example, EP 2 754469 A1).
  • the crampons have claw-like active surfaces on both sides of the ski, which protrude downwards over the sliding surface and thus enable grip in snow or ice.
  • the crampons are often attached on steeper terrain and in icy conditions. When attaching the crampons, the binding must be released and/or the binding completely removed. This creates an unstable situation in which there is a high risk that the ski tourer will slip or the skis will be lost.
  • a well-known climbing aid (GB 2 224448 A), which is placed on the running surface of the skis from below.
  • This climbing aid has an approximately U-shaped base plate which is snapped into the skis from below.
  • a wedge is mounted under the base plate with screws to prevent slipping.
  • the climbing aid is only held on the ski by spring force. It can therefore slip out of the ski because such a fixation is not strong enough.
  • Such a climbing aid has also not established itself on the market at all.
  • the climbing aids can therefore be relatively just loosen and get lost.
  • the wedge does not provide sufficient support when climbing, especially on hard, icy ground.
  • the wedge is heavily mechanically loaded when walking uphill. This can lead to the wedge becoming detached from the rest of the climbing aid over time, as the connection between the two is a detachable screw connection.
  • DE 2612404 A1 relates to a climbing aid for skis, with the climbing aid comprising a vertical bar and elastic clamping brackets.
  • the ski board is pressed in the direction of the web, whereby the clamping brackets are first pushed to the side and then, when the ski board rests on the web, fold back and partially enclose the ski board.
  • the web can have spikes.
  • the climbing aid is only attached to or removed from the ski by means of the clamping mechanism and is designed to be handy.
  • JP S4985276 U shows a climbing aid for skis with a support surface for a ski board and two brackets arranged on the side.
  • the brackets are used to attach straps that are tightened around a user's ski boot. Bars are attached perpendicular to the contact surface, which engage in the snow.
  • DE 1902777 A describes a device for preventing a ski from slipping back during mountaineering.
  • the device is a slip-back brake in the form of a wedge that attaches to the underside of a ski board.
  • a rear bevel of the wedge faces down into the snow and backs up the snow as it slides back.
  • FR 2401674 A1 has a device for attaching an anti-slip strip under a ski.
  • the device includes two L-shaped profiles that can be pushed together and fixed to fit the width of a ski board.
  • U shows a climbing aid device for skiers, the device having a U-shaped cross section with side legs. On the side legs are facing inwards and in pairs opposite each other resilient locking cams arranged between which a ski board can be locked. Flexible straps are attached to the underside of the device, which allow both sliding when driving downhill and support when climbing uphill.
  • the object of the present invention is to create a very simple climbing aid that can be securely attached to waisted skis without having to get out of the ski binding.
  • the climbing aid should be easy to detach and yet always be securely attached to the ski.
  • this object is achieved by a climbing aid for attaching to a waisted ski with the features of patent claim 1.
  • a climbing aid for attachment to a waisted ski with a metal or plastic body, which has an approximately rectangular base plate provided with two transverse edges and two longitudinal edges. At least one upwardly bent clamping spring, which is designed to be elastic, is arranged on each of the two longitudinal edges. At least one downwardly projecting side surface element is formed on the longitudinal edge and/or transverse edge, as a result of which the ski finds a hold in the snow when climbing.
  • the climbing aid is characterized in that the clamping springs are arranged with a clear width that is only a predetermined amount larger than the narrowest waist of the ski, so that the ski is firmly clamped between the clamping springs due to the sidecut when going uphill.
  • the metal or plastic body can be formed in one piece.
  • Two side surface elements are preferably provided.
  • One of the two side surface elements is formed substantially in the longitudinal direction and the other is formed substantially in the transverse direction.
  • the two side surface elements are preferably orthogonal to one another in the longitudinal direction or in formed transversely.
  • the finding/idea on which the present invention is based is that by inserting the side surface elements into the snow, the climbing aid is initially held for entry with skis.
  • the clamping springs then protrude upwards.
  • the ski can simply be snapped into this from above.
  • the ski should be inserted between the clamping springs approximately in the middle from above with its narrowest waist between the clamping springs. By pulling the ski a little backwards, the clamping springs clamp on the cheeks of the ski, which makes it possible to fix the climbing aid on the ski without loosening the binding.
  • the supporting leg continues to pull the ski during the subsequent first ascent steps, whereby the ascent aid is pulled slightly forward with respect to the ski and the clamping between the ascent aid and ski is further fixed.
  • the two orthogonal side surface elements in the longitudinal and transverse direction give the ski support and guidance when climbing up the mountain, especially on hard snow or ice, so that the ski does not slip back or slide sideways.
  • the ski does not need to be unbuckled when putting on the climbing aid. This makes it much easier to get started with the ascent aid.
  • the climbing aid can be put on very quickly.
  • the clamping springs have opposing outward bulges into which the ski is pressed and locked.
  • the ski already finds a certain hold in the ascent aid.
  • Moving forward moves the Climbing aid slightly forward due to its hold by the side surface elements in the snow (or the ski moves slightly backwards), so that the ski is clamped between the bulges due to the waist.
  • this represents a simple and very quick "attachment” or fixation of the ski in the ascent aid.
  • the clear distance between the clamping springs, in particular their bulges is designed in such a way that it is only a predetermined, small distance (e.g. 1 to 7 mm) greater than the narrowest waist of the ski and that the clear height of the bulges is at least the profile height of the Corresponds to skis, a simple fixation of the skis in the ascent aid is quickly achieved. After that, the ski only needs to be moved slightly uphill so that the clamp fixes the ski sufficiently firmly.
  • the small distance is preferably not more than 7 mm, in particular not more than 5 mm, and it can also be not more than 3 mm.
  • the sidecut is designed in such a way that it widens by at least 3 to 5 mm or even more from the narrowest point of the respective ski to a length of approximately 5 cm to 15 cm in the direction of the ski tip.
  • the distance between the clamping springs can be selected so that there is sufficient play to insert the ski into the climbing aid and the inserted ski only has to be moved back 5 cm to 15 cm relative to the climbing aid in order to fix the climbing aid on the ski.
  • the climbing aid is then usually fixed at about the height of the toe piece or a little bit (5 cm to 10 cm) further forward on the ski, which enables a secure hold even on icy ground.
  • the clearance between the clamping springs is preferably at least 0.5 mm or at least 1 mm or at least 1.5 mm and/or at most 4 mm or at most 3 mm or at most 2 mm or at most 1.5 mm or at most 1mm larger than the narrowest waist of the ski.
  • the ski can be pressed between the clamping springs with not too much effort and, on the other hand, the ski has a sufficiently large hold between the clamping springs.
  • the clearance between the clamping springs is preferably dimensioned in such a way that the climbing aid is clamped in the area of the toe piece of the ski binding of the waisted ski.
  • the ascent aid can also be useful for the ascent aid to be in an area from the toe of the ski binding up to about 20 cm or about 15 cm or about 10 cm or up to about 5 cm away from the toe in the direction of the ski tip of the waisted ski Ski is clamped.
  • the position of the ascent aid on the ski is determined by the clearance between the clamping springs. In other words, this means that the clearance between the clamping springs accordingly determines where the climbing aid is to be fixed.
  • the narrowest point of the sidecut is usually on the toe piece or a small distance away from the toe piece in the direction of the ski tip. Then the values given above for the clear distance in relation to the narrowest waist correspond to the positioning of the climbing aid on the toe piece or a little further in the effect.
  • the shaped metal body is advantageously made from a single part by bending surface parts, the climbing aid can be manufactured easily and inexpensively. This means that the parts cannot become detached from one another, even under heavy loads.
  • the side surface element formed in the transverse direction has a toothed tab bent downwards with at least two pointed teeth. This means that the spikes can dig into the ice and hold the ski in place, especially since the ski's clamp between the bulges is steadily tightened during the ascent.
  • the side surface element designed in the longitudinal direction is a side flap bent downwards, which is designed to taper obliquely downwards and backwards essentially to a point, this leads to good lateral guidance for the ski on the one hand and the tip provides additional support on the other. Pulling it out of the snow is also made easier.
  • the pointed shape looks like a conventional crampon.
  • the side surface element which is designed outwards in the transverse direction, increases the effective surface transversely to the slope, so that the grip and the risk of slipping backwards are reduced.
  • a diamond-shaped wing with a lower tip further improves grip against slipping.
  • the clamped ski can be released from the clamping springs by pressing on the exit tongue from above. Because by pressing down, the clear width is increased and the ski is then no longer clamped. This makes it easy to get out of the climbing aid.
  • the exit tongue can simply be pressed down with a ski pole or a ski boot, provided the exit tongue is easily accessible from above and protrudes far enough outwards.
  • the toothed tab can be formed downwards on the front or rear transverse edge. It is advantageous if the toothed tab has the largest possible effective area in the transverse direction and several points downwards, so that a good hold against slipping is ensured. It is therefore favorable, the wider the serrated tab bent downwards at an angle of about 90° at the front transverse edge is, with a sufficiently large number of sharp points. The multiple spikes improve grip in ice and hard snow.
  • the jagged strap can have a further end strap which is bent around a vertical axis and which ensures lateral support when the climbing aid is used.
  • This end flap can be orthogonal or arranged at any other angle.
  • the end tab is preferably bent more than 45° out of the plane of the serrated tab.
  • the spiked tab can also be designed without spikes, for example with only one horizontal edge.
  • Such an embodiment with an end strap can be produced simply by bending a stamped sheet metal part.

  • the two side surface elements are arranged essentially orthogonally to one another, specifically one in the longitudinal direction y and the other in the transverse direction x.
  • the side surface elements which are formed downwards are designed in such a way that they provide a hold in snow or ice. Due to the side surface elements, which are designed approximately orthogonally to one another, the ski 11 not only finds support when walking uphill, but also experiences a certain longitudinal guidance in the snow. This reduces the risk of slipping or slipping back.

  • the jagged strap 23 can have on its lateral edges a further end strap (not shown) which is bent around a vertical axis and which ensures lateral support when the climbing aid is used. As a result, the side straps 21 can be omitted and the climbing aid 10 nevertheless gives the ski lateral support.
  • the ski 11 moves backwards with respect to the climbing aid 10 until the ski 11 is clamped between the clamping springs 20 .

  • the spacer element has, for example, the shape of an approximately U-shaped small plate 51 (FIG. 6), which can engage around one of the two clamping springs 20 in each case.
  • the small plate 51 has a base segment to which two lugs are connected and bent over in such a way that the base segment can be arranged on the inside of the respective clamping spring 20, with the lugs encompassing the clamping spring 20 on its outside.
  • the small plate 51 can thus be pushed onto the respective clamping spring 20 .
  • the clear width 31 between the clamping springs 20 can thus be reduced by up to 2 mm on each of the two clamping springs 20, that is to say by up to 4 mm in total.
  • the spacer elements can also be attached to the clamping springs in other ways.
  • the spacer elements can be made of a polymer material or rubber and can be formed, for example, in the form of a tube, so that they can be pulled over the spring clips.
  • ascent aids 10 do not have to be produced with every imaginable clear width 31 between the clamping springs 20. It is enough to limit yourself to certain sizes. Further intermediate sizes can then be formed using the small plates 51 .
  • FIG. 7 A second exemplary embodiment is explained below (FIGS. 7 and 8). Identical parts have the same reference numbers as in the previous exemplary embodiment. In addition, the above explanations apply equally to the corresponding parts of the second embodiment.
  • the climbing aid 10 has a one-piece metal or plastic body which has an approximately rectangular base plate 15 with an underside 41 and an upper side 42 as a central element.
  • This metal or plastic body can also be referred to as the base body 48 .
  • the base plate 15 also has the two transverse edges 17 running transversely to the ski 11 and the two longitudinal edges 18 running along the ski 11 .
  • the at least two side surface elements 21, 22 are arranged on the underside 41 of the base plate 15 and are designed to project downwards on the longitudinal edge 18 and/or the transverse edge 17.
  • the two side surface elements 21, 22 are arranged essentially orthogonally to one another, specifically one in the longitudinal direction y and the other in the transverse direction x.
  • the side surface elements 21, 22 can be formed in one piece on the base body 48 or, for example, be riveted to it by means of additional tabs.
  • the base plate 15 has a plurality of through holes 43 .
  • the through-holes 43 in one half of the base plate 15 are designed as elongated holes 43 so that, for example, a screw or a bolt 47 can be fixed at different positions within these elongated holes.
  • the elongated holes extend parallel to the transverse edge 17.
  • Two clamping spring modules 49 are provided, which are designed as separate one-piece parts.
  • the clamping spring modules 49 each have the clamping spring 20 and a tab 44 arranged essentially perpendicular to the clamping spring 20 . Taken together, the dimensions of the tabs 44 essentially correspond to the base plate 15.
  • the tabs 44 have through holes 45 corresponding to the through holes 43 so that the clamping springs 20 can be fixed to the tabs 44 by means of screws or bolts 47 on the upper side 42 of the base plate 15 .
  • Conical bodies 46 are provided as counterparts for the screws or bolts 47 on the underside 41 of the base plate 15 .
  • the bodies 46 form prongs which, together with the side surface elements 21, 22, engage in the snow or ice in order to provide a secure hold.
  • the bodies 46 can also have a different shape.
  • one clamping spring 20 can be variably fixed in the transverse direction x, ie parallel to the transverse edge 17 of the base plate 15. In this way, the clear width 31 between the clamping springs 20 can be variably adjusted.
  • the through-holes 45 of the tabs 44 can be in the form of oblong holes which extend in the transverse direction x in order to allow the corresponding clamping spring 20 to be adjustable. Because this climbing aid 10 is designed in a modular manner from a base body 48 and two clamping spring modules 49, it is also possible to design the climbing aid 10 with different clear widths 31 between the clamping springs 20 by providing clamping spring modules 49 of different sizes, in particular with differently sized tabs 44 , In each case the same base body 48 can be used.
  • the spacer elements explained above can also be used in the second exemplary embodiment, as shown schematically in FIG. 6 using the example of a small plate 51 .
  • waist 38 is used in general for waisted skis 11 (carving skis, fun carvers). It means a manufacturing or construction method that has an emphatically narrow middle (narrowest waist in the region of the ski binding 36).
  • a touring ski is a special ski that is used in ski touring and is well known as such.
  • the invention can also be used with other, waisted skis and is not limited to touring skis.
  • ski skins 12 are strapped or glued onto the running surfaces of the skis 11. The ski binding
  • a fictitious coordinate system with x, y, z directions with reference to a ski 11 is used for the description of the climbing aid 10, as is shown in FIG. 2, for example.
  • the terms “top” and “bottom” (z-direction or vertical direction), “front” and “back” (y-direction), “transverse” and “longitudinal” and “outside” (x-direction) refer to here always on a ski 11 into which the ascent aid 10 is engaged and/or clamped .
  • the ski 11 itself essentially has a longitudinal direction y.
  • the base plate 15 is arranged transversely to this, which has four side edges, two side edges (longitudinal edges 18) are parallel to the cheeks 27, i.e. arranged longitudinally, and two side edges (transverse edges 17) are transverse to the longitudinal direction y of the ski 11 arranged.
  • Waisted skis 11 have a waist 38 along the ski 11, the narrowest waist being formed approximately in the middle in the region of the ski binding 36.
  • the ski 11 widens again to the front and to the rear, ie the waist becomes larger.
  • the side surface elements 21, 22, 23 can be arranged pivotably on the base plate 15 and can be fixed in their position of use, so that the climbing aid can be folded up during transport and the side surface elements 21, 22, 23 can be fixed in their position during use.

Abstract

La présente invention concerne un dispositif d'aide à la montée (10) destiné à être adapté sur un ski parabolique (11). Il est constitué d'un corps métallique ou plastique comportant une plaque de base rectangulaire (15). Des ressorts de serrage (20) sont formés dans la direction vers le haut sur les bords longitudinaux (18) du dispositif d'aide à la montée, un ski (11) pouvant être ajusté dans les ressorts de serrage et fixé en place par serrage. Deux éléments (21, 22, 23) de surface latérale sont disposés orthogonalement l'un par rapport à l'autre et font saillie dans la direction vers le bas. Les éléments (21, 22, 23) de surface latérale comportent des pointes (25), lesquelles, lorsque le skieur monte, entrent en prise avec la surface sous-jacente et aident le skieur à se tenir. Au moins un élément (21, 22, 23) de surface latérale, formé transversalement par rapport au ski (11), sert à serrer le ski (11) entre des parties (28) incurvées vers l'extérieur, lesquelles font partie des ressorts de serrage (20) et dans lesquelles le ski (11) a été ajusté.
