Description

I. Field of application

The invention relates to a connection unit for movably connecting two longitudinally adjacent skids.

II. Technical background

There are many different winter sports equipment on the market today, all of which serve to glide on snowy or icy, sloping surfaces. It must be differentiated between systems with a skid or with multiple skids as well as the winter sports equipment with two skids afterwards, whether these skids can be moved independently by the user or not.

The typical case of a winter sports device with two skids to be moved independently of one another is the pair of skis, in which a ski is firmly connected to a foot via a binding. From this, for example, the single skis equipped with a mono-ski was derived in which both legs / feet are mounted on only one skid.

Another representative of a winter sports equipment with only one skate is the snowboard, the track is driven on only one edge. The fixed position of the feet on the mono-ski as well as on the snowboard brings but also some unpleasant side effects such. B. unilateral stress on the muscles with it. To the fascination of swinging on one To combine the edge with the comfort of two independent skis, two-ski systems were developed that combine the positive effects of different systems in one synthesis.

With the idea of combining two edges in one lane, connecting units and systems have been developed that lead two skis in parallel.

1. 1. Verbindungseinheiten zum Parallelführen der Skispitzen und zur Vermeidung des Überkreuzens der Skier
2. 2. Verbindungseinheiten zur parallelen Fixierung der Skier zu einem Mono-Ski
3. 3. Verbindungseinheiten zur parallelen Führung der Skier mit der Möglichkeit des Aufkantens und der Schrittverschiebung in Richtung der Skilängsachse.

Here you can differentiate between different categories that meet the different requirements:

1. 1. Connection units for parallel guiding the ski tips and to avoid crossing the skis
2. 2. Connecting units for parallel fixing of the skis to a mono-ski
3. 3. Connection units for parallel guidance of the skis with the possibility of Aufkantens and the step displacement in the direction of the ski longitudinal axis.

However, such extensions to the ski material also offer new movement qualities and new driving techniques. One of the outstanding quality of motion in the current era is the dynamics of movement of the "cut" turns, "as if on a rail", known as "carving turns".

Characteristic feature of these carving turns is the parallel ski position, as well as the higher speed and the strong to extreme cornering.

These lead to a strong deflection of the skis. The energy stored in the ski due to the strong deflection now in turn provides restoring forces that very good riders use to turn their skis.

The exploitation of these restoring forces (which are also called rebound) is an extremely economic swinging technique, but the ability to move is high presupposes. Only large upright angles and driving force ensure that the ski experiences a strong deflection.

The aim of the invention is to make this fascinating and economical skiing technique available to a large number of beginners and intermediate-level advanced skiers.

In this context, it is from the DE 10 2007 034 228 already known to equip each of the two connection units in front of and behind the ski bindings with two parallel transverse struts, and to use elastic elements such as rubber blocks between these cross struts, which cause a restoring force in the direction of the normal position of the two skis to each other at each edge.

However, the solution there also does not eliminate the general problem that oscillations, which are caused by the substrate into which a skid is introduced, are transferred to the other skid by the connecting mechanism, the better and more strongly the connection between the two Skids is.

From the EP 1263511 is a winter sports device with two skids known, which are connected to each other in the transverse direction via a front and a rear connection unit in the form of cross braces.

In this case, however, only the parallel guidance of the skids with respect to the longitudinal direction is desired, but is not intended by this compound unit compulsory identical edge of the two skids or achieved because the necessary for this joint parallelogram in the connection unit is not present.

From the WO 2012/038554 , Which represents the next leading state of the art, a similar winter sports equipment is known in which in addition to the aforementioned document, a compelling identical edge of the Both skids is intended, which is also possible because of the parallelogram-like leadership of the two skids.

However, there are the ends of the two bars not on both sides in the longitudinal and / or transverse direction relative to the supporting skid in the assembled state, ie in operational condition, movable. A suspension / damping of this longitudinal and / or transverse mobility is not provided.

III. Presentation of the invention a) Technical task

It is therefore an object of the invention to provide a generic connection unit, which is simple and inexpensive to manufacture and transmits vibrations originating from the ground as little as possible from one to the other skid. In addition, preferably the connection units should be detachable from the skis.

b) Solution of the task

This object is solved by the features of claims 1 and 15.

Advantageous embodiments will be apparent from the dependent claims.

The basic idea of the invention is based on driving a winter sports device with two skids side by side, wherein the two skids are mechanically interconnected in the front and rear each in the transverse direction, that the two skids are vibration decoupled, ie shocks and vibrations when driving from Substrate conditionally into which a skid be initiated, not or only greatly attenuated transmitted to the other skids.

In addition, preferably, the mechanical cross-connection should be carried out so that an edge of a skid forcibly causes a Aufkanten the other skid.

Furthermore, the mechanical cross-connection can be performed so that a longitudinal displacement of the skids relative to each other as a step shift is possible.

By the longitudinal and / or transversely movable attachment of the cross member relative to the supporting skid by means of a compensation device and in particular the arrangement of a spring element and / or a damper element therebetween at each end of the connection unit - of course preferably with effective direction in the direction of mobility the attachment of the crossbar - are limited movements of the connecting unit with respect to the supporting skid possible and in particular sprung and / or damped. This avoids or at least greatly reduces the forces that result from the connection unit, for example, originating from the other skid, in the skid in question to undesirable vibrations or movements.

This compensation device is preferably arranged between the bearing block and the respective skid, because there comparatively much space is available for this purpose. Between bearing block and cross strut such a compensation device is rather disturbing.

The spring element and the damper element may be separate elements or else a combined spring / damper element (combi element), in the simplest case a block made of rubber or another elastic material.

However, the direction of action of the spring element and the damper element should preferably match, which is the easiest to achieve in a combination element.

Preferably, the mobility and / or the spring / damper effect should also be in the horizontal transverse direction, in particular in all directions, so all three spatial directions, given the effect in the vertical is less important.

A mobility and thus suspension and damping only in the longitudinal and transverse direction already compensates almost all transmitted from a skid on the connection unit forces and movements on the other skid.

However, a particularly simple and yet highly effective variant is to provide limited mobility with suspension and damping only in the longitudinal direction, since the connection unit is almost never exactly at right angles to the longitudinal direction, shocks in the direction of the connection unit at an angle connected to the longitudinal connection unit without problems in a longitudinal movement relative to the skid.

The maximum mobility, in particular in the longitudinal direction, including the movement of the spring element and / or damper element should be from the normal position of at most +/- 60 mm, better at most +/- 40 mm, better at most +/- 20 mm, but this at least +/- 3 mm, better at least +/- 10 mm, better at least +/- 15 mm.

Preferably, the effect of the spring element and also of the damper element should be adjustable in order to adjust the behavior of the connection unit depending on the background and ambient conditions.

To accommodate the spring-damper element, the connecting unit preferably comprises at each end a base plate which can be screwed onto the skid, wherein the bearing block is guided in the longitudinal direction of preferably sliding guides of the base plate. Between bearing block and base plate then the spring element and / or the damper element is arranged, for example by the base plate has recesses, for. B. in their end portions in the longitudinal direction, which are each open to their front and rear end side. Therein blocks of elastic material such as rubber can be used as a spring-damper element, against which a stopper body of the bearing block abuts when it is moved in the longitudinal direction.

Of course, other elements such as shock absorbers, steel springs, pneumatic cylinders or the like are possible, but more expensive to use.

In this case, the stopper body between two combined spring-damper elements such as rubber blocks, be included, or one or more such spring-damper elements are located between two longitudinally spaced stop bodies of the bearing block.

The properties of the connection unit are further improved when the pivot axes about which each cross member is pivotable relative to its bearing block, not only extending in the longitudinal direction obliquely to the horizontal, but also the point of articulation of the cross member on this pivot axis is located as far down the bearing block, in particular already protrudes down into the height range of the surface of the skid or is at most 20 mm above it. As a result, the vertical lever is minimized and reduced or avoided rotations of the skid about the longitudinal axis.

Especially in order to achieve a restoring force in the normal position when edge up, each connection unit preferably not only one, but two parallel transverse struts, which are connected to each other via elastic return elements, such as rubber blocks.

This causes both in the deflection of a transverse strut about its pivot axis, ie on the bearing block, or even with relative movement of the two transverse struts in their longitudinal direction relative to each other in each case a restoring force in the normal position. For this purpose, the pivot axes of the two transverse struts at each end of the connecting unit by 10 to 20 mm, in particular by about 15 mm, offset from one another.

This behavior is additionally favored and stabilized by the fact that although the pivot axes extend in the longitudinal direction, they are neither horizontal nor vertical to the horizontal, wherein preferably all the pivot axes of a connection unit have the same skew angle.

Likewise, it is preferable that both cross braces of a connecting unit are the same length, resulting in the same size in both directions upright of the skids. Preferably, the two bearing blocks are combined at one end of the connection unit to a common bearing block, which facilitates the structural design.

The transverse struts are rigid at least in the direction perpendicular to their pivot axis formed, however, in the direction of the pivot axis, resilient, so be resilient.

The cross struts are preferably not attached with their ends directly to the hinges, but have downwardly facing extensions, for example, from round rod material, the z. B. are welded to the tube material of the cross braces, which are mounted with their free ends in the pivot joints of the bearing blocks.

In addition, the cross struts are rotatably mounted about the longitudinal axes of these extensions, which is necessary if in addition to the upright movement and a step offset of the skids takes place in the longitudinal direction.

By the extensions a greater distance of the cross struts is achieved upwards relative to the skids, which is necessary to allow a sufficiently strong edge of the skids without these abutment with an edge at the bottom of the crossbars.

A winter sports device with two coupled skids can be prepared with two of the above-described connection units by z. B. in a pair of skis in each case one connection unit before and one mounted behind the commercial bonds. The connection units are also easy to disassemble so that the winter sports equipment can be used either with or without coupling.

In the longitudinal mobility of the linkage units on the skids and their spring and damping action, the damping action is preferably set to be stronger upon moving the corresponding end of the connecting unit onto the binding than away from the binding, at least 10 % stronger, better at least 50 % stronger, better at least 80 % stronger, but no more than 200 %, better at most only 150 % stronger.

The connection units are preferably mounted so that the pivot axes of the bond from each rise forward and backward.

The cross struts are preferably slightly curved, so bent upwards, formed. This creates a lot of scope for the edge of the skids.

Further, the restoring forces between the cross braces, so the restoring elements mounted there, are chosen so that at the rear connection unit a stronger return effect, so stronger return elements or more return elements, are present as at the front connection unit.

Except for the different restoring action, the two connection units can be identical.

For better understanding, first the winter sports equipment 1 as a whole and the connection unit 3 a, b used in this case is written in general, while the description of the spring / damper unit according to the invention only at the end, in particular with reference to FIGS. 1 d . e he follows.

As the FIGS. 1 a and b show, the winter sports equipment 1 according to the invention consists of two parallel in the longitudinal direction 10 parallel skids 2 a, b, on which the user is fixed with one foot, so shoe, and the two transverse connecting units 3 a, b , one in front and one behind the bindings 18 for the shoes, are joined together.

The two skids 2 a, 2 b each carry in their approximately central area a commercially available security binding 18 in this case consisting of a binding plate 20 which is mounted on the top of the skid 2 a, b, and in the rear and front area the binding plate 20 respectively attached front and rear binding jaws 18 a, b, between which the shoe is fixed.

Before the front binding jaws 18 a and behind the rear binding jaws 18 b are each transversely of the one skid 2 a to the other skid 2 b extending connecting units 3 a, b, arranged at their two ends on each of the skids 2 a, b, are attached.

How best that FIGS. 2 a to d show, each of the connection units 3 a, b in this case consists of two transverse struts 5 a, b, whose long cross-sectional axis is inclined to the main plane of the skids 2 a, b.

The cross struts 5 a, b are pivotally mounted with their free ends 6 a, b respectively in a bearing block 7 a, b as a rotary joint 12 a, b, which are combined on each side to a common bearing block 7 , and wherein each bearing block 7 on one of the two skids 2 a, b is attached, as best in the FIGS. 1 a . b to recognize.

The pivot axes 17 a, b of the ends 6 a, b of the transverse struts 5 a, b in the bearing block 7 a, b extend in the longitudinal direction 10 of the skids 2 a, b, but preferably not parallel to the horizontal main plane of the winter sports equipment, the bearing surface the sliding surfaces 4 a, b of the skids 2 a, b corresponds in the neutral position on the flat surface, but at an angle of about zero to 60 ° inclined thereto, namely the ski center, so to the binding 18 out, in this case sloping.

When edge of the skids 2 a, b, such as in FIG. 3 a, the two transverse struts 5 a, b are moved in the transverse direction 11 relative to each other. As restoring elements 25 here rubber elements 8 between the two transverse struts 5 a, b are arranged, for. B. in the central region and with one end of these, for example, cylindrical rubber elements 8 attached to one of the transverse struts 5 a, b, in particular screwed, or also vulcanized.

In the direction of the transverse struts 5 a, b can be arranged more such rubber elements 8 , for which in particular prefabricated through holes in the cross braces 5 a, b may be present.

The fact that the pivot axes 17 a, b of the two transverse struts 5 a, b in the bearing blocks 7 a, b - as in Fig. 2 c and d seen - although each viewed in the plan view in the longitudinal direction 10 , viewed in the side view but offset in the longitudinal direction 10 and preferably parallel to each other, each connection unit 3 a, b with its two transverse struts 5 a, b is a parallelogram of forces.

This has the consequence that when edge of one of the skids, z. B. 2 a, ie a pivoting of the skid 2 a about its longitudinal axis 10 relative to the two attached thereto connection units 3 a, b, automatically due to the parallelogram of forces of the connection unit and the other skid 2 b bent in the same direction, ie about the longitudinal axis 10th is pivoted, which simplifies the practice.

If the length of the two transverse struts 5 a, b of a connecting unit 3 a, b is the same, the two skids 2 a, b are also bent by the same angle.

The transverse struts 5 a, b consist for example of a flat material, in particular of steel, aluminum, titanium, optionally made of spring steel. Of the particular arcuate upwardly curved cross braces 5 a, b extend extensions 24 at the ends down to the bearing block 7 a, b zoom and are pivotally mounted about the pivot axis 27 with their free ends on the pivot 12 a, b.

The cylindrical rubber elements 8 are with its longitudinal axis substantially parallel to the pivot axes 17 a, b in the bearing block 7 extending between the flat transverse struts 5 a, b screwed to which they rest with one of their faces. Thus, the rubber elements 8, the same inclination of their rubber shafts 9 on how the pivot axes 17 a, b, and the cross section of the flat cross struts 5 a, b and also the projections 24 have a reverse inclination to the skid 2 a, b, since they are at right angles to the direction the pivot axes 17 a, b and the rubber elements 8 extend.

In order to bring the transverse struts 5 a, b in alignment with respect to the longitudinal axis of the rubber elements 8 , despite the offset of the pivot axes 17 a, b in the longitudinal direction 10 , the extensions 24 of the two transverse struts 5 a, b are of different lengths, as also in Fig. 2 c to recognize.

In addition, the transverse struts 5 a, b about the longitudinal extent of the extensions 16 a, b pivotally, which are bolted querragend for this purpose on the pivot 12 a, b, and the screw serves as a further pivot axis, which is needed because the two Skids 2 a, b to each other not only can be tilted, but also for the desired step displacement offset in the longitudinal direction 10 may have.

Fig. 2 A shows a connection unit from the front, so that the slightly arcuate curved cross member 5 a, b is visible from its broad side, with the three holes in this case for possible screwing of a respective rubber element. 8 Each end of the transverse strut 5 a, b ends with its attached thereto extension 16 a, b in one of the bearing blocks 7, ie a swivel joint 12 a, b.

FIG. 3 a shows the connection unit in the same direction as in Figure 2 a , ie from the front, but with bearing blocks 7 , which are inclined, ie are deflected about the pivot axes 17 a, b with respect to the transverse struts 5 a, b and although inclined analogously, as is the case when edge of a winter sports equipment with two skids ,

In the supervision of the Fig. 2 b are in addition also the between the two transverse struts 5 a, b screwed in this case, three rubber elements 8 can be seen.

As best in the side view of the Fig. 1 b can be seen when attaching the connecting units 3 a, b on the skids 2 a, b from the currently most commonly encountered situation a binding plate 20 between the actual ski binding 18 and the skid 2 a, b has been assumed:

In this case, a binding plate 20 , which is significantly longer than the actual ski binding, on the skid 2 a or b attached by looking - viewed in the side view - in the middle firmly against the skid 2 a or b is screwed.

The front and rear ends of the binding plate 20 are also screwed relative to the skid 2 a, b to hold them on the skid, but the screw head can move along the top of the binding plate 20 , for example in a longitudinal groove, which is then necessary when the skid 2 a, b is bent in the vertical direction, whereby the distance between the middle screw and the front and rear screw can change. As a result of this shaping, the skid 2 a, b is not unduly stiffened in its middle region and can still be deformed vertically there as well.

The actual binding 18 in the form of the front and rear binding jaws 18 a, b is then firmly screwed only on the binding plate 20 , but the screw is not enough in the skid 2 a, b into it.

By virtue of the fact that the binding plate 20 is longer than the actual binding 18 , the connecting units 3 a, b can be placed in the region in front of and behind the binding on the binding plates 20 , if one is present and long enough, but the connecting units 3 a . b also be mounted separately and directly on the skids 2 a, b, as shown in the drawings.

However, attaching the connection units 3a, b on the binding plate 20 is easier:

Because often the binding plates 20 are designed so that the binding jaws 18 a, b in the longitudinal direction 10 , z. B. from behind, on the skid already screwed binding plates 20 need only be postponed and then already in all transverse directions 11 are positively fixed by the binding plate 20 , as in Fig. 1 c can be seen, has a cross section, with the underside of which it is screwed onto the skid 2 a or b. In this case, the cross section has downwardly cranked outer edges, which do not reach the top of the skid 2 a, b, so that a corresponding downwardly open, contour of the underside of the binding jaws 18 a, b - Fig. 1 c shown - can positively engage under this bent-down edge, and thus is positively fixed both in the horizontal transverse direction 11 and in the vertical direction.

In the same way, ie with the same C-shaped profile at the bottom of each bearing block plate 19 for sliding in the longitudinal direction 10 on the binding plate 20 , which is then also the base plate 14 , or a separate, analogous to the edges, base plate 14 , which is bolted to the respective skid 2 a, b, each bearing block 7 of the connection unit 3 a, b be equipped so that the connection units 3 a, b can be easily pushed in the longitudinal direction 10 and at the desired position only by introducing vertical clamping screws 21 are secured.

The special feature of the invention consists in the limited longitudinally 10 movable, preferably also sprung and damped attachment the bearing blocks 7 , so their bearing blocks 19 , with respect to the skids 2 a, b:

A first design is in Figure 1 e such as FIG. 2 a is shown on the left bearing block 7 :

The fixedly screwed on the skid 2 a base plate 14 has in the longitudinal direction 10 extending at its lateral edges guide rods with, for example, round cross-section as a longitudinal guide 15. Further, on this base plate 14 in the longitudinal direction 10 complained each rubber body as a combined spring / damper elements 13 screwed, in this case as approximately annular discs, which are screwed at its from the center of the base plate 14 opposite outer end on this base plate 14 .

In the longitudinal direction 10 is relative to the base plate 14 slidably mounted above the bearing block plate 19 which has at its edges a guide sleeve 15 ' , with which it is guided on the guide rods 15 . In the center of the above the base plate 14 lying bearing block plate 19 protrudes from this a stopper body 22 down between the rubber body 13 with a length corresponding to the distance between the rubber bodies 13th

If now - be it by unevenness of the ground or for whatever reason - the bearing block plate 19 is displaced in the longitudinal direction 10 , it presses against one of the rubber body 13 and presses it together, whereby the longitudinal movement of the bearing block plate 19 is increasingly attenuated, and is subsequently by the elasticity of the rubber body 13 , which acts as a spring, moved back into the starting position by the rubber body 13 relaxed again.

The bearing blocks 7 and thus the connection units 3 are thus limited relative to the skids 2 movable, which is the structure of natural oscillations or avoids the transmission of vibrations from a skid 2 a on the other skids 2 b.

In FIG. 1 d as in FIG. 2 a right side shows an even simpler design with the same effect:

The base plate 14 is in turn firmly screwed to the skid 2 b, and has the bent-down edges, which do not reach the skid, as in Figure 1 c illustrated and explained.

In contrast, and in the longitudinal direction 10, in contrast, displaceable and guided is the bearing block plate 19 , which engages with its lateral edges, the edges of the base plate 14 and is thereby guided in the longitudinal direction 10 .

In the end regions in the longitudinal direction 10 of the base plate 14 are recesses 16 which are open to the end faces of the base plate 14 and beyond, for example, to the top and / or bottom of the base plate 14 are open. In these recesses 16 , for example, disk-shaped, in-fit rubber body 13 are inserted, which are held for example by an overlapping edge of the base plate 14 in position.

At the ends of the bearing block plate 19 projects from this a stopper body 22 down again into the height range of the rubber body 13 and with a width which is less than the opening width of the recesses 16 in the base plate fourteenth

Thus, when the bearing block plate 19 is displaced in the longitudinal direction 10 , one of the stopper body 22 presses against one of the rubber bodies 13 , deforms it, is damped in its movement, and the elastic elastic return movement of the rubber body 13 presses the bearing block plate 19 back to its neutral position, in which the stopper body 22 just as possible rest against the respective rubber body 13 without bias.

The combined by the rubber body 13 two functions of suspension and damping can also be realized separately, for example by a coil spring as suspension and a hydraulic damper as a damper, which, however, results in much more complex designs.

Figure 1 c on the other hand shows the pure longitudinal mobility between the base plate 14 and bearing block plate 19 without suspension or damping.
