Description

Technical area

The invention relates to a snow sports equipment.

State of the art

Snow sports equipment in the form of sliding boards are known, especially skis and snowboards. With existing snow sports equipment one has either an optimal departure device or an optimal ascent equipment. If snow sports equipment used to upgrade, z. B. ski touring, so usually climbing skins are applied by hand to the bottom of the ski and removed for departure again. The attachment takes place in particular by means of an adhesive, supportive and mechanical fasteners are used. Alternatively, skins can adhere to the ski through adhesion.

With an optimal downhill device, it rises badly and with an optimal ascent device, it goes off badly.

The requirements for snow sports equipment are opposite in the ascent and on the descent. The following properties are advantageous: In the ascent: On the departure: - lightweight - heavy weight - low sidecut - strong sidecut - narrow contact surface - wide contact surface - climbing skin against slipping back - Sliding surface

In addition, the application and removal of climbing skins is very tricky (especially in wind and weather). The adhesive properties of climbing skins diminish with each change, and even wet or frozen skins may not stick.

Presentation of the invention

The task is to further develop a snow sports equipment in such a way that it shows improved characteristics both on the descent and in the ascent.

1. a) der Mittelteil auf einer Unterseite einen Gleitbelag aufweist,
2. b) die Seitenteile von einer ersten Position, in welcher eine erste Hauptfläche der Seitenteile im Wesentlichen koplanar ist mit der Unterseite des Mittelteils, in eine zweite Position umklappbar sind, in welcher die Seitenteile unter den Mittelteil geklappt sind, so dass die ersten Hauptflächen der Seitenteile auf der Unterseite des Mittelteils abgestützt sind, und wobei
3. c) zweite Hauptflächen der Seitenteile, welche den ersten Hauptflächen gegenüberliegen, ein Steigfell aufweisen.

The solution of the problem is defined by the features of claim 1. According to the invention, the snow sports equipment comprises a gliding board with a flat middle part which extends in a longitudinal direction, and two flat side parts which are attached on both sides to the middle part, wherein

1. a) the middle part has a sliding surface on a lower side,
2. b) the side parts are foldable from a first position, in which a first major surface of the side parts is substantially coplanar with the underside of the middle part, to a second position, in which the side parts are folded under the middle part, so that the first main surfaces of the side parts are supported on the underside of the central part, and wherein
3. c) second major surfaces of the side parts, which lie opposite the first main surfaces, have a climbing skin.

Both the central part and the side parts thus extend in both the first and in the second position substantially in the same longitudinal direction. In the first position, the side parts are arranged in the transverse direction next to the middle part, so that at least on the underside, preferably also on the upper side, a continuous main surface is formed. In the second position, the side parts are folded around a longitudinal axis substantially 180 ° below the middle part, the second main surfaces of the side parts are parallel to the underside of the middle part, at a distance which corresponds to the thickness of the side parts.

The climbing skin may be a fur in the narrower sense, but it can - as is well known - also be realized by artificially applied structures or special introduced into the surface materials. The central feature is that the climbing skin prevents the gliding board from slipping backwards but allows it to slide forward.

The invention can be used in particular in connection with conventional touring skis, but also with so-called splitboards, ie snowboards, which can be divided for ascent in the longitudinal direction.

The advantage of the invention is that the snow sports equipment can be brought into a second configuration ("downhill") by simply flipping it over from the first configuration ("ascent"), in which it is narrow and on the underside equipped with a climbing skin , in which it is wide and equipped on the bottom with a sliding coating. Due to the additional increase by the flip-over results in the rise of an increased grip level. The cumbersome attaching and removing the skins is completely eliminated and also the risk that the skins do not stick once. Nevertheless, there is an increased buoyancy and a better Einlenkverhalten in the downhill due to the folded-up side panels.

Advantageously, the side parts at a lying in the first position edge on a departure edge and on the first main surface on a sliding coating. The side panels thus fulfill both the ascent (climbing skin) and the downhill (sliding surface, departure edge) completely the function of the corresponding areas of known sliding boards with or without attached climbing skin.

Preferably, the middle part has a main portion with a substantially constant width along the longitudinal direction, and the side parts have a sidecut in a portion whose longitudinal extent corresponds to that of the main portion of the middle part. In particular, the main portion includes substantially the entire length of the gliding board except for the front blade area and optionally an area at the rear end of the gliding board.

In the first position of the side parts for the descent is a waisted sliding board, the waist can basically be optimally aligned to the downhill. By folding the side parts in the second position results in a narrower sliding board, which is substantially unsized, because the boundary of the sliding board is no longer formed by the now inner waisted outer shape of the side parts but by the substantially straight outer shape of the middle part. The narrow, unsized gliding board is well suited for the ascent.

Alternatively, the invention can also be implemented in connection with (substantially) unshaped gliding boards.

Advantageously, the climbing skin is fixedly applied to the second main surface. This means that it will not be removed under normal use. Of course, it may be useful to replace the climbing skin after a certain period of use. This will usually be done in a workshop.

The fixed attachment can be done in a simple and cost-effective manner, for. B. with a suitable adhesive. The risk that the climbing skin will dissolve within the scope of normal use is minimized.

In a preferred embodiment, a hinge mechanism is disposed between the central portion and each of the side portions, the hinge mechanism preferably being formed by a band which is mounted flat on a side surface of the center portion and on a side surface of the side portion. The hinge mechanism or the band in particular have the task of holding the respective side part axially and in a direction perpendicular to the main surfaces of the main and side part in its position. Suitable bands are made of a durable material, eg. B. from a fiber-reinforced, flexible plastic tape. You may be glued with one of its major surfaces with the mentioned side surfaces of the main and side part, which adjoin one another in the first position.

Instead of bands, the hinge mechanism may be realized by other elements, e.g. B. by classic hinges. The hinge mechanism may be substantially continuous or include a plurality of spaced apart members in the longitudinal direction of the sliding board.

In a further preferred embodiment, the middle part and the side parts are connected to each other by at least one cable. By tensioning the cable or the cables, the side parts mechanically coupled particularly well to the central part, especially in the first position. By loosening the cable or the cable a change in position of the side parts is made possible.

In a splitboard, the cable pull or the cable pulls can also be used to attach the two parts of the splitboard together.

Preferably, the at least one cable pull comprises a cable which is guided through through openings in the middle part and in at least one of the side parts, as well as a tensioning and locking mechanism for tensioning and locking the cable when the at least one side part is in the first or second position. A cable can connect the middle part with both side parts, or there are separate cables for the two side panels available. A side part can also interact via several cables with the middle part. In a preferred configuration, there are two cable tracks, one in the front part of the gliding board (before the binding area) and a second one in the rear part of the gliding board (behind the binding area), both of which co-operate with both side parts.

The passage openings and further guide elements for the cables are advantageously guided in such a way that the course of the cables does not fall below certain minimum radii of, for example, 30 mm, in particular 40 mm. Thus, the operating force can be kept in a range which allows easy manual operation.

Suitable tensioning and locking mechanisms for cable pulls are known. For example, Boa Technology Inc. of Denver (CO), USA has corresponding products available on the market.

Advantageously, the through openings are arranged in the middle part and in the at least one side part such that the cable extends completely within a base body of the middle part and the at least one side part in the first position of the at least one side part in a contact region of the middle part and the at least one side part.

The contact area here forms those areas of the middle part and the side part, which adjoin one another and in which they are connected to each other by the cable pull. Preferably, the cable extends substantially completely within the middle part and the side part and at most emerges upwards in the case of an actuating element in a middle region of the middle part from the main body of the middle part. The hidden arrangement of the cable is aesthetically advantageous, but also improves the safety on the descent by hanging the cable, z. B. on protruding roots or branches or other objects is impossible.

Preferably, the snowsports device comprises means for locking the side members in the second position, the means comprising members for mutually securing the side members together. As a result, the side panels can be easily locked in the second position. The elements for mutual fastening may be, in particular, hook-like fittings arranged at a distance from one another in the longitudinal direction, which connect the two side parts essentially in the transverse direction and are completely accommodated in the intermediate space between the two side parts. These fittings can automatically engage each other when folding the side panels, or they are manually operated by the user.

The locking of the side parts can be done in other ways, for example by the side parts are fastened with their first major surface on the underside of the middle part, z. B. magnetically or by mechanical elements.

A snow sports device according to the invention may have locking elements arranged on an upper side of the middle part for supporting the side parts in the first position. These locking elements support the side parts against the pressure exerted from below. They are used instead of or in addition to the cable, possibly only partially along the longitudinal extent of the sliding board.

Advantageously, the middle part on a top side on a cover sheet, wherein the cover sheet projects laterally beyond a base body of the central part to support the side parts in the first position. This measure can also be used in addition to or instead of the cable pull and / or the locking elements.

In general, depending on the design of the hinge mechanism or the cable lock locking elements, a protruding cover sheet, both measures or none of them can be used.

The side parts preferably have a plurality of segments in a blade region of the sliding board and / or are made of a flexible material. The segments are arranged one behind the other in the longitudinal direction and separated or connected by a resilient material. The flexible material may be a rubber material. This allows an adaptation of the folded side part of the bend in the blade area.

Advantageously, the side parts at a lower edge in the second position gripping means to improve the grip when climbing in hard terrain. In this case, the outer, the inner or both edges can be equipped with these gripping means. The gripping means are in particular edges, elements or surfaces of a suitable material and with a suitable geometry or profiling. The gripping means can take over the function of a harsche iron wholly or partially or in some situations make the use of a Harscheisens unnecessary.

Advantageously, a base body of the central part relative to the top and bottom obliquely extending side surfaces, and the main body of the side parts have correspondingly inclined side surfaces which cooperate in the first position with the side surfaces of the central part such that it acts on the underside of the side parts transfer vertical forces to the middle section. As a result, in particular, the connection between the middle and side parts is relieved.

Preferably, a container is mounted on the sliding board, which can be filled with snow to increase a dead weight of the snow sports equipment for the descent. This improves the smoothness of the snow sports equipment. The container may be bounded at the bottom by the top of the middle part and at the top by a net. The net allows easy execution and simplifies filling.

The container for filling with snow is basically also in connection with a snow sports equipment without hinged side panels feasible and there combines the advantages of a lightweight sliding board for the climb and a heavier sliding board for the downhill.

From the following detailed description and the totality of the claims, further advantageous embodiments and feature combinations of the invention result.

Ways to carry out the invention

The FIG. 1 shows a plan view of an embodiment of the inventive snow sports equipment. The top view shows the departure position. At the snow sports equipment It is a ski 1, which is particularly suitable for touring. It comprises a central part 10 with a substantially constant width over the entire length of the ski 1, as well as two waisted side parts 20, 30, which are arranged on both sides on the central part. The waist of the side parts 20, 30 is such that in a central longitudinal section of the ski 1 results in a reduced ski width, corresponding to a conventional sidecut of skis. Approximately in the region of minimum ski width is that region 11 in which a binding is arranged on the middle part 10. The side parts 20, 30 comprise sections 21, 31 in the blade area, which - as described in more detail below - are specially designed so that they can adapt to the curved shape of the blade of the ski 1 when the side parts 20, 30 are folded over.

The FIGS. 2A, 2B show schematic cross sections through the snow sports equipment in the downhill and in the ascent position. In the in the FIG. 2A shown departure position, the side parts 120, 130 arranged laterally of the central part 110, in which in FIG. 2B As shown, they are located below the middle part 110.

The middle part 110 comprises a main body 113, which may be formed in a manner known per se from skibau, it comprises, for example, a hard foam core which is enclosed along its main surfaces by a top flange or a bottom flange (eg made of aluminum or glass-fiber reinforced plastic) is. On the upper side, the main body 113 is covered by a cover sheet 112. On the underside of the main body 113, a laminate layer 114 and a sliding coating 115 are arranged.

The layer structure of the side parts 120, 130 is substantially analogous to the middle part 110 in an inner region: Instead of the cover sheet, a climbing skin 127, 137 is fixedly arranged on the upper side of the side parts 120, 130. This does not extend to the inner end surface, so that a recess is formed on the upper side. In the in the FIG. 2A As shown, the cover sheet 112 of the central portion 110 extends beyond the side portions 120, 130, and the outermost portions of the cover sheet projecting beyond the center portion 110 are received by the recesses of the side portions 120, 130.

Below the climbing skin 127, 137 or the recesses in turn is followed by a base body 123, 133, which is constructed analogously to that of the middle part. Subsequently, a laminate layer 124, 134 and a sliding coating 125, 135 follow. The laminate layer 124, 134 and the sliding coating 125, 135 do not extend to the outer side surface of the side parts 120, 130, but rather in the region of these layers from a departure edge 126 , 136 formed. In the downhill position, the side parts 120, 130 are fastened to the middle part 110 in such a way that the usual structure of a ski with a continuous sliding surface and lateral edges results.

In the in the FIG. 2B shown rise position, the two side parts 120, 130 are folded under the middle part 110. The lowest surface of the ski is thus formed by the climbing skins 127, 137 on the side parts 120, 130. The cover sheet 112 protrudes slightly beyond the side surfaces of the center portion 110. The height of the ski is increased, the width is reduced.

The FIGS. 3A, 3B show schematic cross-sections through a second embodiment of the snow sports equipment in the downhill and in the ascent position. In the in the FIG. 3A shown departure position, the side parts 220, 230 arranged laterally of the central part 210, in which in FIG. 3B As shown, they are located below the middle part 210.

The middle part 210 comprises a main body 213, which may be formed in a manner known per se from skibau, it comprises, for example, a hard foam core which is enclosed along its main surfaces by a top flange or a bottom flange (eg made of aluminum or glass-fiber reinforced plastic) is. On the upper side, the main body 213 is covered by a cover sheet 212. On the underside of the main body 213, a laminate layer 214 and a sliding coating 215 are arranged.

The middle part 210 has a trapezoidal cross-section, wherein a width from above (ie, starting from the cover sheet 212) decreases downwards (towards the sliding surface 215). Accordingly, the side parts have a sloping inner end surface, such that in the downhill position according to FIG. 3A complete the cross sections to the desired overall cross section of the ski.

The layer structure of the side parts 220, 230 is substantially analogous to the middle part 210 in an inner region: instead of the cover sheet, it is on the upper side of the side parts 220, 230 a climbing skin 227, 237 fixedly arranged. Below the climbing skin 227, 237 in turn is followed by a base body 223, 233, which is constructed analogously to that of the middle part. Subsequently, a laminate layer 224, 234 and a sliding coating 225, 235 follow. The laminate layer 224, 234 and the sliding coating 225, 235 do not extend to the outer side surface of the side parts 220, 230, but rather in the region of these layers from a departure edge 226 , 236 formed. In the downhill position, the side parts 220, 230 are fastened to the middle part 210 in such a way that the usual construction of a ski with a continuous sliding surface and lateral edges results.

In the in the FIG. 3B shown rise position, the two side parts 220, 230 are folded under the middle part 210. The lowest surface of the ski is thus formed by the climbing skins 227, 237 on the side parts 220, 230. The height of the ski is increased, the width is reduced, starting from the top (the cover sheet 212 of the middle) down (on the climbing skins 227, 237) decreases.

In another embodiment (not shown), the middle part has a trapezoidal cross-section, the width of which increases from above (i.e., starting from the cover sheet) downwards (toward the sliding surface). Correspondingly, the side parts have an inner end surface running obliquely in another direction, such that in the downhill position the cross sections complement the desired overall cross section of the ski.

The FIG. 4 is an oblique view of the front part of the first embodiment in the departure position. The side part 20 of the ski 1 is folded up and forms with the central part 10 a continuous sliding surface 15, 25 and a continuous upper side, wherein the upper side of the side part 20 is formed by a climbing skin 27. Locking levers 41, 42 are pivotally mounted on the central part 10 about vertical axes and transmitted from below on the side part 20 transmitted forces on the central part 10. They thus prevent a pushing up of the side part 20 beyond the position shown.

The FIG. 5 is an oblique view of the front part when folding a side panel. So it shows an intermediate position between the departure and the ascent position. The side part 20 is arranged on the central part 10 of the ski 1 via a band 50. This band 50 is made of, for example, a fiber-reinforced elastomer and is firmly bonded with one of its major surfaces to the outer side surface of the central portion 10 and the inner side surface of the side portion 20. The other major surface of the band 50 is free. In the FIG. 5 are also the climbing skin 27 and a rise edge 28 can be seen.

The FIG. 6 is an oblique view of the front part in the ascent position. The side part 20 is thus completely folded under the middle part 10 of the ski 1. The climbing skin 27 now forms the underside of the side part 20. The side surface of the ski 1 is formed by the band 50, the rise edge forms the outer lower edge of the ski first

The FIG. 7 is an oblique view of a front part of a third embodiment with segmented blade portion of the side part. The side part 320 is in turn arranged laterally on the middle part 310 of the ski 301. In the blade area of the side part 320 but now comprises a plurality of segments 321.1, ..., 321.5, which are mounted laterally in the usual manner on the central portion 310, z. B. via a belt, but only in the longitudinal direction via a flexible material portion attached to each other. This allows folding the segments 321.1 ... 5 under the blade area of the ski 301 with different pitch angle. On the upper surface of the segments 321.1 ... 5, in turn, a climbing skin 327 may be arranged, in the foremost segments 321.4, 321.5 this may not be necessary, because they will not usually come into engagement with the ground.

The FIG. 8 shows a plan view of a front part of a fourth embodiment. In this embodiment, the side parts 420, 430 are connected to the central part 410 via a cable pull 460. For this purpose, the middle part 41 and the side parts 420, 430 comprise channels extending inwardly parallel to the main ski surface, in which the cable pull 460 is accommodated. The channels run alternately in the middle part 410 and one of the side parts 420, 430, wherein in a foremost part of the course of the cable 460 from the (seen from above) left side, starting from the side part 420 through the middle part 410 through to the right side, in the Side part 430 runs. At the far end the course of the cable of the cable is first led by the side parts 420, 430 in the middle part 410 and there relax in a tensioning device 461, with which the cable by turning a knob of the tensioning device 461, by pressing the button. Such clamping devices 461 are known and available on the market, namely from Boa Technology Inc., Denver (CO), USA.

The channels in the side parts 420, 430 and in the middle part 410 are shaped so that a maximum angle of curvature does not fall below a certain value, that the cable of the cable 460 thus does not have to make abrupt, directional change leading to great resistance. The mouths of the channels in the side parts 420, 430 and in the middle part 410 are matched to one another, so that the side parts 420, 430 are arranged at tensioned cable both in the longitudinal direction and in the vertical direction at the middle part 410. In the transverse direction, the side parts 420, 430 are fixed to the middle part 410, so that functionally a uniform sliding board is formed in the downhill position.

A similar (not shown here) cable train runs in the back of the ski 401st

By pressing the buttons of the tensioning devices, the cables of the cable pulls are released, and the side parts 420, 430 can be folded down, below the middle part 410. There they can, as mentioned above, be connected to one another by hook-like connecting elements running parallel to the main surfaces of the central part 410. Then the cables are stretched again to ensure a tight fit. Thus the ascent position is reached.

In order to get back to the downhill position from the ascent position, first the cable is loosened, then the connecting elements. By tensioning the cables, the side parts 420, 430 are folded up again and get into their arrangement for the departure position.

The invention is not limited to the illustrated embodiments. Thus, structural details can be carried out in other ways, or elements of different embodiments can be combined. The invention is not limited to skis, but also for example in so-called splitboards used.

The sketched inner structure of the ski is to be understood only as an example, in principle, the invention with the most currently known structures feasible.

In summary, it should be noted that the invention provides a snow sports equipment which shows improved properties both on the descent and in the ascent.
