Definitions
- the invention relates to a ski, a snowboard or the like.
- Skis in particular are known in a wide variety of designs. It is also known to provide damping areas in the ski body to improve the damping or suppression of uncontrolled vibrations in the ski body, for example by introducing permanently elastic materials into the core or ski body, in particular in the binding area.
- the object of the invention is to show a snow sliding element which is distinguished by a particularly effective damping and thus by improved driving properties.
- a snow sliding element is designed according to the characterizing part of claim 1.
- a damping element for use in such a snow sliding element is designed according to the invention in accordance with the characterizing part of patent claim 10.
- the damping effect is based on the fact that at least two elongate damping members are provided, which are arranged adjacent to one another over a larger partial length such that they overlap on this partial length and are displaceable relative to one another, so that a damping region is formed. Outside this area, the damping members are positively connected to one another at a connecting area and to the core of the snow sliding element, preferably to an upper flange provided on this core, above the neutral bending zone of the snow sliding element, so that each time this element bends inevitably a postponement of the Attenuators relative to each other and thus a damping effect occurs.
- the attenuators have an elongated shape.
- the respective damping element is integrated in the ski body.
- the area at which the attenuators of the at least two groups overlap is sealed or sealed against the ingress of resin to the outside, which is achieved, for example, by a housing and / or by the space between the overlapping attenuators is filled with a permanently elastic material. The latter also contributes to damping.
- 1 is a ski which, or its elongated ski body, forms a shovel area 2 with a ski tip 3 at one end and a binding area 5 between this tip 3 and the rear ski end 4, to which the binding (not shown) is attached to the top of the ski body is.
- the ski body consists of a core 6, which is made of suitable ski building materials, and of an upper and lower base layer (upper flange 7 and lower flange 8) adjoining this core 6, the two belts 7 and 8 e.g. are made of metal and / or another suitable material, for example fiber-reinforced plastic, etc.
- a layer sequence 9 adjoins the lower flange 8, which forms the underside or running surface 10 of the ski and is laterally delimited by the steel edges 11.
- the core 6 is laterally delimited by a cheek 12, which is supported with its underside on the steel edge 11 there.
- a suitable material for the side walls is a plastic, for example a styrene derivative, e.g. SECTION.
- the ski body is closed by a shell 13 made from a plastic film.
- damping elements 14 are provided in front of and behind the binding area 5, namely integrated in the ski body above the upper flange 7 and below the shell 13.
- damping element 14 which extends in cross section of the ski body over the greater part of the width of this ski body.
- the damping element 14 is shown in more detail in FIGS. 2-4. It consists essentially of several strip or tongue-shaped attenuators or lamellae 15, for example made of a flat or strip material by cutting and punching, which form two groups or stacks, in which the lamellae lie one above the other and are arranged with their larger surface sides facing one another are. At one end 19 of each stack 16 or 17, flat spacers 18 are arranged between the lamellae 15, which are also made of a flat material which has approximately the same thickness as the thickness of the flat material used for the lamellae 15.
- the lamellae 15 of each stack 16 or 17 are connected to one another, for example by gluing and / or by a continuous mechanical fastening element, for example by a rivet. Furthermore, the slats 15 and also the spacers 18 are provided on the long sides by punching with notches or recesses 20.
- the stacks 16 and 17 or the damping area are enclosed by a housing 21 which extends over the greater part of the length of the damping element 14 extends, in such a way that only the two ends 19 provided with the recesses 20 protrude from the housing 21.
- a housing 21 which extends over the greater part of the length of the damping element 14 extends, in such a way that only the two ends 19 provided with the recesses 20 protrude from the housing 21.
- the part of the damping element 14 on which the lamellae 15 of the two stacks 16 and 17 lie adjacent to one another, ie the effective part of the damping element 14 (damping area) is hermetically sealed to the outside.
- Each damping element 14 is arranged on the ski 1 so that it lies with its longitudinal extension in the direction of the longitudinal extension of the ski or the ski body, namely in the middle of the width of the ski body. With the two ends 19, each damping element 14 is positively connected to the upper flange 7, for example by means of screws, rivets or in another suitable manner.
- the recesses 20 also ensure that the ends 19 are integrated into the ski building materials, which fill the space between the top of the shell 13 and the top of the top flange 7. Since the interior of each damping element 14 is hermetically sealed by the housing 21, it is prevented that resins used in particular in the manufacture of the ski penetrate into the damping element 14 and could render it ineffective.
- the space for accommodating the damping elements 14 is created in that the shell 13 is arched like a hood at 13 '.
- the damping elements 14 are located above the upper belt 7 and thus above the neutral bending zone of the ski 1 and are also connected at both ends at 19 to the upper belt 7, the slats 15 of the two stacks move relative to each other when the ski 1 is bent 16 and 17 to each other, whereby an effective damping of the deformation of the ski 1 in the region of the front ski and in the region of the rear ski is achieved by rubbing the fins 15 together.
- a permanently elastic material for example an elastic plastic
- This permanently elastic layer has the advantage that, on the one hand, it reliably prevents the penetration of resin during the manufacture of the ski into the respective damping element, but on the other hand also contributes to the damping effect by means of elastic deformation forces.
- FIG. 6 shows, in a representation similar to FIG. 5, a ski 1a as a further embodiment, in which a plurality of damping elements 14a are provided next to one another in the transverse direction of the ski, in the illustrated embodiment two narrower damping elements 14a, the shell 13 in this embodiment is designed in such a way that it forms a hood-like region 13 'for each damping element 14a, so that the ski 1a clearly has two parallel, bulge-like, upwardly projecting regions at the top where the damping elements 14a are provided.
- FIGS. 7 and 8 show an embodiment in which a damping element 14b forms two damping regions, specifically a damping region 23 in front of the binding region 5 and a damping region 24 behind the binding region 5.
- the damping element 14a uses a total of three stacks of damping members or lamellae, namely two outer stacks, each of which the stack 16 or 17th are designed accordingly, that is, in turn, consist of the attenuators or lamellae 15, which are connected to one another at one end 19 via spacers 18. Between the two outer stacks 25, which correspond to stacks 16 and 17, a middle stack 26 is provided, which is formed by damping members or lamellae 15a, which in turn are produced by cutting and / or punching from a flat material or a strip-like material, but with a longer length. Spacers 18a are arranged in the middle of the stack 26 between the lamellae 15a, and the lamellae 15a are connected there in a suitable manner via these spacers, for example by gluing, riveting, etc.
- the slats 15 of the two stacks 25 are inserted from both sides into the stack 26 or into the space between the slats 15a not occupied by the spacers 18a, so that each slat 15 of each stack 25 has at least one slat over the greater part of its length 15a is adjacent and thereby the damping area 23 or 24 is formed.
- Each damping area is in turn hermetically sealed off from the outside by a housing 21a corresponding to the housing 21, it also being possible with the damping element 14b to introduce a permanently elastic material into the respective housing 21a, which then forms layers 22 between the slats 15 and 15a , and / or to provide a casing made of this permanently elastic material instead of the housing 21a.
- the damping element 14b is fastened to the ski body in such a way that the central part 19a of this damping element is fixed to the ski body or upper belt 7 in the binding area 5 and one end 19 to the ski body or upper belt in front of the binding area 5 and the other end 19 to the ski body or Upper chord 7 is firmly connected behind the binding area.
- the fins 15 and 15a consist, for example, of metal and / or plastic, preferably of a fiber-reinforced plastic. In principle, it is also possible to combine these materials, for example in such a way that part of the fins 15 and 15a are made of metal and another part of these fins Plastic, etc. Basically, the same material is suitable for the spacers 18 as is also used for the slats or damping members 15.
- the housing 21 is, for example, one made of plastic.
- FIG. 9 shows a damping element 14c as a further possible embodiment.
- This damping element consists of a plurality of damping members 27, which are accommodated in a packet-like manner next to and / or one above the other in the interior of a housing 28 which is closed towards the outside.
- the tube-like or hose-like housing 28 consists of a deformable material, preferably of plastic.
- the housing 27 is tightly closed.
- the damping element 14c forms the damping area between the two ends 29, and with these two ends the damping element is fastened to the area of the ski body to be damped, for example the upper belt 7.
- each damping member consists of two individual elements 27 'and 27' ', of which the individual element 27' is preferably a wire as a wire made of spring steel and the individual element 27 '' is designed as a tube or cannula.
- the individual element 27 extends into the individual element 27 ′′ and is displaceable in this element.
- the outer diameter of the individual element 27 ' is adapted to the inner cross section of the individual element 27' 'in such a way that braking and thus damping displacement of the elements 27' and 27 '' is possible relative to one another.
- This damping effect can be supported in that the element 27 'made of a resilient material was slightly curved before being inserted into the element 27' '.
- the element 27 ′′ extends from the right end there, on which this element is held with the corresponding elements of the other damping members 27, to the vicinity of the left end in FIG. 9 29, but ends at a certain distance from this end.
- the single element Analogously, 27 ′′ extends from the left end 29 in FIG. 9, at which the individual element 27 ′ is connected to the similar individual elements of other damping members 27 and to the housing 28, up to the vicinity of the right end 29, points from this end but a certain distance.
- damping members 27 partially in an arrangement in the housing 28 that is opposite to the position described above.
- FIG. 11 shows an embodiment in which each damping element 30 of the damping element 14d in each case forms a plurality of damping regions, namely a total of four damping regions in this embodiment.
- each damping member consists of two individual elements 27 ′′, into each of which a wire-shaped individual element 27 ′ is inserted from both sides, in such a way that the two individual elements 27 ′ are still spaced apart from one another within each individual element 27 ′′.
- the outer individual elements 27 ' are each fixed at their outer ends, the individual element 27' provided between two individual elements 27 '' and also these individual elements 27 '' are each fixed in the middle, i.e. with corresponding individual elements of the other damping members 30 and with the housing and, via this, connected to the region of the ski to be damped.
- the individual elements 27 ' consist of metal.
- the individual elements 27 '' consist of metal or plastic.
