Description

Austrian Patent Office AT506 545B1 2012-05-15

Description: The invention relates to a board-type gliding device, in particular a cross-country ski, alpine ski or a snowboard, whose flexural rigidity and thus also its usage behavior can be changed individually by means of a setting device, as indicated in claim 1.

Board-type sliding devices are known from the prior art, which in the lower flange, in particular below the neutral fiber of Gleitbrettkörpers at least one tension element, in particular ropes or straps, which can be biased by means of an adjustment in their mechanical bias variable within certain limits. This is intended to change the hardness, in particular the stiffness or flexibility of the sliding board body. Such gliding board bodies are known from US 4,577,886 A, US 2,918,293 A, FR 927 897 A, FR 1 109 560 A, DE 14 28 941 A, AT 247 763 B or EP 0 086 983 B1. The proposed adjustment devices allow a variable adjustment of the tension in the respective tension elements. After adjustment, which can be carried out partly with tools or tool-free, this setting is usually maintained after the cost of conversions is each considerable. If a plurality of adjusting devices are formed, then these act independently on different sections, in particular on the front and rear end portion of the sliding board body.

From DE 33 15 638 A1 a ski with a device for increasing the flexural rigidity is known. In this case, a tension-resistant but flexurally elastic, at least over a portion of the ski length extending band is provided in the longitudinal direction. This guided at the top of the ski band is supported relative to the Schioberseite by means of at least one vertically extending to the Schioberseite support. To change the stiffness of the ski this support is designed to be adjustable in height between the elastic band and the Schioberseite. The disadvantage here is that this elastic band acts on the upper flange of the gliding board body, in particular upsetting the upper belt, whereby the ski tip or the ski end is lifted or lifted in the manner of a drawbridge when the band running on the ski side is more strongly biased by the supports ,

In addition to the known from the prior art designs with tension members are also known designs, which pressure rods, i. Have loaded on thrust elements in order to influence the flexural rigidity or the flexibility of a board-like slider adjustable. Such embodiments are described, for example, in US 2005/0206128 A1, DE 10 2005 040 088 A1 or EP 0 730 890 A2. The last-mentioned document describes an embodiment with bi-directional adjustment device. In particular, an adjusting device is proposed therein, which can exert either either tensile forces or compressive forces on mutually distanced sections of a sliding board body. Although these known adjustment devices allow a change in the hardness or flexibility of Gleitbrettkörpers, but the achievable with these adjustment benefits to the end user, especially for the sports practitioners, only partially satisfactory.

US 2,188,582 A discloses a generic board-type sliding device. A running inside this board-like sliding device, can be acted upon with different or adjustable tensile stresses tension element is coupled at its front end with an adjustment, which has a folding lever and a so-called turnbuckle. The opposite, rear end of the tension element is connected to an anchor plate, which is supported load-bearing at the rear end of the sliding board body. The connection of the tension element with the end anchor plate is subject in particular during use of the board-like sliding high, sudden loads. The corresponding anchoring is thus relatively robust or voluminous perform, which set the sliding board body adverse weight ratios or unfavorable contours occur and space situations at the rear end of the sliding board body.

FR 2 800 624 A1 discloses a ski binding with a built therein device for changing the Schiwölbung or the balance of power in the upper flange of the ski body. Here, a fine and a coarse adjustment is provided, wherein both adjusting act on a single tensile strand in the form of relatively rigid threaded rods or bolts. The fine adjustment comprises a nut and associated threaded rods with left- or right-hand thread. The coarse adjustment comprises a T-piece at an end remote from the nut one of the two threaded rods. This T-piece can be hung in one of several recesses on the mounting plates for the binding body. The effect of this schibindungsseitige adjustment on the mechanical properties of the sliding board body is only partially satisfactory.

The DD 230 782 A1 also describes a device for varying the stress of a ski Schiängsrichtung extending in the longitudinal direction, arranged in the ski tension element whose front and rear end is attached to the ski. In the central region of the clamping element, a clamping device for changing the bias of the clamping element is arranged, said clamping device is operable starting from the surface of the ski. The tensioning element is arranged in the ski in such a way that its force application points, starting from the ski tip in the direction of the ski end, are on the one hand in the region of the end of the front sliding zone and on the other hand in the region of the beginning of the rear sliding zone. Between these two force application points, the tensioning device is arranged. This clamping device has a protruding from the ski surface threaded bolt, whose opposite end is provided with a arranged in the Schikern clamping piece. At the projecting end of the threaded bolt on the ski surface, an actuating eccentric rotatable both about the axis of the threaded bolt and pivotable about the axis of the connecting pin is mounted by means of a connecting pin. Between the Schioberfläche and the Betätigungssexzenter a sealing element and a pressure plate is arranged. This prevents the ingress of dirt, snow or water in the area of the tensioning device into the interior of the ski structure. Although this embodiment with the sealing element around the threaded bolt improves the practicality with respect to a sufficient tightness and functionality of this adjustment, the problem of high stress on the clamping element during the use of such Schier remains completely disregarded in this document.

The present invention has for its object to provide a board-like gliding device, in particular a cross-country ski, alpine ski or snowboard, which can be best adapted not only to the physical ability or biometric properties, in particular to the body mass of a user, but which also allows the best possible adaptation to different or changing use or use states. A further object of the invention is to provide a board-like gliding device, in particular a cross-country ski, which enables relatively inexperienced users to exercise as optimally as possible and which has technical aids in order to be able to increase the performance achievable with the gliding device.

This object of the invention is achieved by a board-like sliding device according to the features in claim 1. It is advantageous that such a sliding device can be well adapted by providing a presetting and a Zusatzzeinstellvorrichtung on the one hand a relatively large circle of different users with different abilities or divergent physiological properties and beyond at least a temporary change in the properties of the board-like gliding device of the respective Users can be made in a relatively short term in a simple manner. The presetting device allows a pre-setting or a preparatory basic setting, which is mainly based on the biometric properties, in particular on the body mass of the respective user. This pre- or default setting is made primarily by the dealer or preferably by the distributor of a sliding device according to the invention and usually no longer changed. If necessary, the user can also carry out the basic adjustment or the basic setting himself or, if necessary, adapt it before using the corresponding sports equipment. Moreover, especially the end user of the gliding device, i. the sports practitioner, if necessary, the stiffness or flexibility of the sliding device by means of the additionally provided Zusatzzeinstellvorrichtung change very quickly. That the user or athlete can switch by means of Zusatzzeinstellvorrichtung relatively promptly and effortlessly to another characteristic of the sliding device quasi.

In particular, there is a need for the user of the sliding device in some situations to change the rigidity of the sliding device at least temporarily. For example, in the management of downhill sections with cross-country skis, it may be desired to achieve optimal sliding performance to change the stiffness of the cross-country skiing short term or spontaneous, in particular to increase. With primary interest in utilizing the braking characteristics of the cross-country ski, it may be desirable to reduce the stiffness of the cross-country ski in the binding mounting section. Subsequently, there may again be a need to restore the original basic or default settings of the gliding device as quickly as possible and fail-safe. These requirements can be met relatively easily and particularly quickly with the additional adjustment. Especially in cross-country skis or so-called backcountry skis, it is advantageous to change the bending stiffness or the flexural stiffness distribution of the gliding device temporarily. Especially for longer descents, which may have curvy sections, it may be particularly advantageous to increase the stiffness of the gliding device spontaneously to avoid unwanted braking of the gliding device due to the central climbing section help. For this purpose, the user increases the rigidity or bending hardness of the sliding device by a predetermined value in the short term and in a simple manner by actuating the additional setting device. Consequently, the user can still exploit the sliding properties of the gliding device even if he unevenly loaded the two skis of Gleitgerätpaares or strong one-sided, such as. when cornering tends to occur. Thus, the user of the gliding device can change the characteristics of the gliding device on the one hand to a relatively large extent and on the other hand relatively spontaneously by activating the additional setting device and thus the bending stiffness at least temporarily, i. For example, during a long descent, increased. Subsequently, the user can disable the Zusatzatstellstellvorrichtung in a simple manner again and thus restore the required especially for classic cross-country skiing, optimized change behavior between sliding and repulsion phase. This means that with the embodiment according to the invention a particularly simple and short-term increase and decrease of the bending stiffness of the sliding device is made possible by a predetermined value. This "off-setting" and "re-setting" The flexural rigidity can be carried out under relatively adverse environmental conditions, especially in the open field and also when wearing gloves. The additional adjustment device is preferably also activated or switchable when the gliding device is loaded with the weight of the user or athlete. This means that the operation or switching of the additional setting device is preferably also possible when the user is connected to the gliding device via the binding device, that is, the sports device is currently in use. The operation of the adjuster can be done by hand and / or foot actuation relatively quickly and conveniently and preferably without the need for additional tools. In a time comparison, concerning a certain change in the stiffness of the slider by a certain value or by a certain amount, the desired stiffness change of the slider from the preset value on the presetting device by simple operation or switching the extra trained Zusatzzeinstellvorrichtung in any case significantly faster achievable or feasible. The provision of the sliding device on the defined by the presetting stiffness value can be done by deactivating the Zusatzzeinstellvorrichtung on the one hand particularly quickly and effortlessly and on the other hand very fail-safe.

A particular advantage of the embodiment of the invention lies in the fact that thereby the robustness of the tension elements or of the tension-relevant organ can be increased 3/52 Austrian Patent Office AT506 545B1 2012-05-15 be. In particular, the loads acting on the tension element are divided by the two- or multi-stranded course of the tension element, so that their risk of damage or breakage is minimized.

By the measure according to claim 2, the probability of incorrect operation or undesirable changes to the adjustment can be significantly reduced. In particular, this is usually no longer changed by the intended user after a corresponding adjustment made the presetting. For short-term changes in the characteristics of the gliding device, the user actuates only the Zusatzzeinstellvorrichtung as needed and he can thus change the characteristics of the gliding device abruptly, in particular increase its bending stiffness and subsequently abruptly lower again. At least the handle for actuating or switching the additional setting device is accessible to the end user of the sliding device at any time, in particular formed on the surface or top of the sliding device and thus spontaneously actuated when needed.

Due to the configuration according to claim 3, the projecting from the top of the slider elements are reduced to a minimum, whereby the number of openings or openings in the slider is kept to a minimum. Due to the small number of protruding from the top of the slider elements also the clarity regarding the operation of the adjustment is increased or minimized the likelihood of confusion of the respective functions.

The embodiment according to claim 4 characterizes a handle, which has two different modes of operation, on the one hand to operate the presetting and on the other hand, the additional setting or to operate. These mutually different types of actuation allow a sufficiently distinctive selection between the presetting and the Zusatzatinstellvorrichtung, so that incorrect operation can be largely excluded. The rotation or rotatability of the handle about the first axis allows the application of high actuating forces and the achievement of further control ranges and a sensitive pre-adjustment of the flexural rigidity of the sliding device. On the other hand, with the pivoting or tilting of the handle, a powerful or abrupt change of these default values is made possible, so that the requirements for a temporary, short-term variability of the flexural rigidity of the sliding device are taken into account by means of a single handle. In particular, two different, optionally applicable types of actuation are provided for this multifunctional handle.

By the measures according to claim 5 is quasi an "overdrive switch". created with which the bending stiffness of the gliding device increased at short notice by a certain value and subsequently lowered again. This is particularly the case for exceptional or non-average sections, e.g. for longer valley runs or steep slope sections, of particular advantage. Above all, by means of the additional setting device, the characteristic of the sliding device can be adapted quickly and easily to the prevailing ambient or operating conditions. This ability to be reconfigured is particularly advantageous, for example, in so-called backcountry skis, which represent a mediocre dimension between cross-country skiing and alpine skiing and are used predominantly in unpaved or unprepared terrain.

The measures of claim 6 allow the construction of a particularly robust presetting device, which also allows a relatively finely graduated and regionally far-reaching presetting the rigidity of the sliding device. In addition, by using a spindle assembly with a low pitch with a relatively low operating force, a high tensile force can be generated. In addition, such a presetting is also longer-term particularly reliable and extremely maintenance-or. wear. It is also advantageous that no additional locking mechanisms are required to maintain the respective desired preset secured. A self-locking 4/52 Austrian Patent Office AT506 545B1 2012-05-15

Presetting can be achieved solely by appropriate choice of the thread pitch of the spindle assembly.

By the measures according to claim 7 far-reaching adjustment ranges can be created after the drum assembly and longer sections of the tension element can easily be wound up and unwound.

In the embodiment according to claim 8 is advantageous that in a simple manner, a self-locking presetting is created, which ensures easy operation and a reliable mechanical structure. In addition, the load acting on the tension element is kept as low as possible and still a significant change in the tension or preload values in the lower flange of the sliding device can be achieved.

The measures according to claim 9, a relatively wide range of adjustment for the presetting can be achieved even in confined spaces for the handle. In particular, by pump-like actuation of the handle, a continuous raising or lowering of the preload values of the presetting device can be achieved.

According to the embodiment according to claim 10, by varying the anchoring points between the tension element and the handle, a finely graded, individually variable change of the preload values of the presetting device can be achieved. The respective required operator actions are intuitively recognizable by the user, so that there is no training or explanation requirement.

The measures of claim 11 provide a Zusatzatinstellvorrichtung that can be operated very quickly and their additional effect on the bias of the presetting when needed can be activated suddenly and also deactivated again. After the Zusatzzeinstellvorrichtung has only a relatively few adjustment positions, quasi a switching operation is available, which saves the user a tedious handling. In addition, the user can quickly and instantly recognize in which operating state the additional setting device is present.

By means of the measure according to claim 12, a spontaneous change of the preload values, in particular of the tensile stress values, on which at least one tension element can be achieved. This operation is particularly fast and easy to carry out. In addition, it is ensured by the deflection of the at least one tension element that the respective default setting of the presetting is not changed or is not adversely affected.

By the measure according to claim 13, the Zusatzzeinstellvorrichtung in a simple manner can exert high forces on at least one tension element, whereby the effectiveness of Zusatzzeinstellvorrichtung, in particular the so-called "offset". the bias voltage change is relatively large and thus the characteristic of the satzein device is sufficiently distinctive.

An embodiment according to claim 14 can be mechanically relatively simple and this is also longer-term particularly reliable in function. A distance variation between mutually parallel tension elements is particularly effective in terms of recoverable tension change. Furthermore, this embodiment is relatively gentle for the tension elements, so that a long-term reliability of the Zusatzatinstellvorrichtung is achieved.

By the measure according to claim 15, an advantageous structural combination between elements of the presetting of Zusatzatinstellvorrichtung is created. In particular, the additional adjustment device is provided by an axial adjustability of the traveling nut arrangement or the adjusting spindle, with which an abrupt raising or lowering of the respective, preset adjustment values of the presetting device is achieved. The advantageous additional setting device according to claim 16 allows a rapid increase and decrease of the preload values in the respective tension element. The power development or the movement sequence of an actuating cam arrangement and the operating ergonomics of such an auxiliary setting device have a positive effect on the operator of the auxiliary setting device. In particular, when using an actuating cam arrangement, a favorable path to force ratio can be achieved.

In the embodiment according to claim 17 is of advantage that the actuating cam assembly is subjected to pressure and thus separate locking mechanisms can be made unnecessary when the actuating cam assembly is pivoted upon activation of the long actuating cam slightly beyond their over-center position.

By the measures according to one or more of claims 18 to 22, the influence of the tension element on the achievable adjustment range of the flexural rigidity is significantly increased. In particular, its effect on the bending stiffness or flexibility of the sliding device can be substantially increased by such a guided tension element. In any case, with a relatively moderate change in the tension in the tension element, a relatively large change in the bending stiffness can be achieved. This means that with relatively low tensile forces on the tension element significantly more intense or distinctive bending stiffness influences can be achieved.

The features of claim 23 characterize a robust and long-term functionally reliable presetting, which also offers easy operation.

Due to the configuration according to claim 24, especially rope or band-shaped tension elements can be particularly functionally reliable and long-term maintenance-free integrated into the structure of the sliding device.

By the measures according to claim 25 a comfortable operation of the adjustment is possible and the adjustment is also close to the usual field of view of the user, so that he can always control the respective settings relatively comfortable and change if necessary.

By the measures according to claim 26, a relatively bendable tension element can be integrated into the sliding board body in an advantageous manner, wherein the tensile forces which can be applied with this tension element are particularly high. Another advantage is that high biasing forces can be achieved by the cable-like leadership of the tension element even with the application of relatively low tensile forces on the Zugende of the tension element in the lower flange of the sliding board body.

The particularly advantageous embodiment according to claim 27 and / or 28 allows the application of high actuating forces at relatively low operating forces. In addition, such an adjustment is structurally simple and extremely robust. Furthermore, such a configuration can be constructed relatively compact and long-term maintenance.

By the measures according to claim 29, the wedge or spreading effect of the at least one wedge element is transferred to the tension elements such that their tensile stress is variable within a sufficient adjustment range. Elaborate deflection or return measures for the tension elements can be made unnecessary and this provided for a tensile force traction elements can be claimed in conjunction with wedge assemblies in a relatively optimal manner to train.

The measures according to claim 30 ensures that the wedging action of the respective wedge assembly can be reliably and structurally robust transferred to rope-shaped tension elements.

Also advantageous is an embodiment according to claim 31, characterized in that an actuator is provided, which always rises in spite of different setting states uniformly over the top of the slider or on the top of the housing for the adjuster. This minimizes the risk of injury and ensures a visually pleasing appearance.

Another advantage is an embodiment according to claim 32, since thereby production or. component-related tolerances in the structure of the sliding device or in terms of its bending characteristic better balanced, i. can be at least partially eliminated in a simple manner. This will make it easier to reach the target or target planned by the producer. Optimum values achieved. In addition, this can reduce the scattering of properties within a series of sliders determined by a variety of factors.

The features according to claim 33 characterize a Zusatzatinstellvorrichtung, which allows an immediate change in the characteristics of the sliding device according to individual needs and, for example, rapidly changing conditions of use or environmental conditions optimally meet. In particular, the user can change the characteristics of the sliding device as needed during active sports exercise, this change in the rigidity or characteristic of the sliding device can be done very quickly and without the need of tools or aids.

The switching function according to claim 34 ensures rapid availability and deactivability of operating states with increased and comparatively lower flexural rigidity of the sliding device. As a result, the usage behavior of the gliding device can be adapted in the short term to changing conditions or to changing needs in a simple manner.

In Fig. 1, a first embodiment of a board-like sliding device 1 is illustrated with an adjusting device 2 for individually changing or influencing its flexural rigidity or its flexibility with respect to elastic bends about an axis extending transversely to its longitudinal axis. Preferably, this gliding device 1 is formed by a cross-country skiing 3, since its flexural rigidity or flexibility in cooperation with different users essential for the achievable performance, i. is particularly important for the respective usage behavior or use behavior. In particular, it is of increased importance that the weight and / or the athletic ability and / or the running style of the respective user are optimally matched to the flexural rigidity of the cross-country ski 3 in order to achieve a good performance, as is well known. Especially to achieve an optimum transition between the climbing or repelling phase and the sliding phase of the cross-country ski 3, it is necessary that its flexural rigidity or its flexibility is optimally matched to the technique or to the weight of the user of the cross-country ski 3.

An individual adjustability or adaptability of flexural rigidity or flexibility is also particularly useful in alpine skis or snowboards and the claimed adjustment device 2 can also be used or applied in this genus of board-type gliding devices 1 for gliding on snow or ice.

The respective sliding device 1 has, in a generally conventional manner, a construction or design-related predetermined preload height 4 and flexural rigidity. Under the preload height 4 is to be understood that bow height, which is present between the underside of an unloaded sliding device 1 and a horizontal support plane of the sliding device 1. The pretensioning height 4 and the flexural rigidity of the sliding device 1 are decisive for the climbing and sliding behavior or for the curve or driving behavior of the gliding device 1. The structural or design-related bending stiffness and preload height 4 is thereby mainly by the choice of appropriate Obergurt- and Untergurtmaterialien for the sliding board body, determined by the shape, by the cross-sectional geometry, by their lengths and also by the nature of the connection between the individual components of the sliding board body.

Apart from this structural stiffness or flexibility of the Gleitgerätes 1 also an adjustment device 2 is provided, based on which the user or lender of such Gleitgerätes 1, the bending stiffness and thus the performance of the Gleitgerätes 1 to a certain extent, i. within a certain range of values, can individually change or adapt. This adaptation takes place taking into account the weight or ability and other parameters that are useful for achieving an adequate usage behavior.

The adjusting device 2 comprises at least one tension element 5, 6 via which between predetermined sections 7, 8 of the sliding device 1 an adjustable, i. a variable within certain value limits tension can be applied. The predetermined or in the longitudinal direction of the slider 1 to each other distant sections 7, 8 are preferably in the end portions or close to the ends of the sliding device 1, i. It is advantageous here, the first and second part section 7, 8 of the sliding board body or the force application points or ends of the at least one tension element 5, 6 in the Close range of support points of an unloaded sliding device 1 to provide on a flat support surface. However, the sections 7, 8 or the force introduction zones for the tension elements 5, 6 can also be displaced slightly closer towards a binding device 9 in the middle section of the sliding device 1.

The respective selected longitudinal position of the sections 7, 8 significantly determines the effect of the adjusting device 2 and the tension elements 5, 6 with respect to the variability of the flexural rigidity of the sliding device 1. In particular, with relatively close together sections 7, 8, the effect of the adjustment 2 relative to the static and dynamic properties of the sliding device 1 is relatively low, while at relatively widely spaced sections 7, 8, the effect of the adjustment device 2 on the flexural rigidity of the sliding device 1 is comparatively higher.

The at least one tension member 5, 6 designed to transmit tensile forces is for the most part in the lower chord, i. in the normally loaded on train section below the neutral fiber of the sliding device 1. In particular, the at least one tension element 5, 6 extends either in the tread surface or on the side of the tread surface facing the core of the gliding device 1. Optionally, the tension element 5, 6 extend partly on the side facing away from the core of the tread surface. This is particularly effective in the sections 7, 8. The closer the tension element 5, 6 is assigned to the tread surface or the further the at least one tension element 5, 6 is distanced from the neutral fiber or zone, the greater is its effect on the bending stiffness or on the flexural stiffness characteristic of the sliding device 1 ,

The at least one tension element 5, 6 is carried out tensile such that the applied by means of the adjustment device 2 forces and the forces acting by elastic deformation movements of the sliding device 1 forces are absorbed breakage or tear. The tensile strength or tear limit is therefore several 100 N. The at least one tension element 5, 6 is preferably designed as a rope, but can also be designed as a band or as a thin, flexible flexible flat profile. It is essential that the at least one pulling element 5, 6 absorb the tensile forces generated by means of the adjusting device 2 and can transmit them to the mutually distal sections 7, 8 of the sliding device 1. Transverse to the longitudinal direction of the at least one tension element 5, 6, these are made relatively flexible or flexible, so that their bending stiffness on the flexural rigidity of the sliding device 1 has a negligible effect. The influence on the flexural rigidity of the sliding device 1 results primarily on the basis of the individually adjustable tensile stress in the at least singularly executed tension element 5, 6.

According to the illustrated embodiment in Fig. 1, the manually operable adjusting device 2 is positioned to change the bending stiffness or to change the so-called flex behavior of the sliding device 1 immediately in front of the binding device 9. As a result, the adjusting device 2 is arranged approximately in the longitudinal center section of the sliding device 1 and can thus be operated comfortably and relatively easily integrated into the sliding board body. Preferably, the adjusting device 2 and its actuators are thus in the front portion of the sliding device 1, i. arranged in the section between the binding device 9 and the tip of the sliding device 1. As will be explained in more detail below, it is alternatively also possible to position the adjusting device 2 in the rear region behind the binding device 9 or within the binding mounting zone.

Preferably, therefore, starting from the centrally positioned adjusting device 2, at least one pulling element 5, 6 runs in the direction of the distal end sections of the sliding device 1. Alternatively, however, it is also possible to adjust the adjusting device 2 in a first end section or partial section 7 or 8 to position the slider 1 and to guide at least one tension element 5, 6 in the remote from the second end portion or section 8 or 7 of the sliding device 1, as will be described below.

It is essential that the adjusting device 2 on the one hand a fine adjustment or at least one presetting 10 for finely graded or continuous, in particular continuous change in tension or for presetting the tension of the at least one tension element 5, 6 and further comprises a coarse adjustment device or a Auxiliary setting device 11 or a corresponding switching device for abrupt or abrupt change or influencing the tension between the distan each other 9-52 Austrian Patent Office AT506 545B1 2012-05-15 decorated sections 7, 8 of the sliding device 1 includes. This means that the setting device 2 by means of the presetting 10 on the one hand allows an individual fine adjustment or a preselection of a certain desired tension and on the other hand by means of Zusatzzeinstellvorrichtung 11 a sudden change, in particular an abrupt increase and reduction of the tension or alternatively a sudden activation and deactivation the tension of the at least one tension element 5, 6 allows.

Comparisons between the required setting times on the presetting device 10 and on the additional setting device 11 show that with equivalent or analog stiffness influencing the sliding device 1 - on the one hand by means of presetting 10 and on the other hand by means of Zusatzzeinstellvorrichtung 11 - the required input or Changeover times at the Zusatzinstellvorrichtung 11 are noticeably lower. This is achieved, for example, by differing ratios of translation or leverages, wherein the total possible setting range on the presetting device 10 is preferably greater than on the additional setting device 11. To achieve this, the presetting device 10 can comprise spindle drives or threaded adjusting devices, for example, whereas the additional setting device 11 Having comparatively faster convertible lever or eccentric devices. Preferably, the presetting device 10 and the additional setting device 11 are operatively connected in series, so that by means of the additional setting device 11, the preset via the presetting 10 traction can be increased if necessary by at least a predetermined range of values and suddenly lowered again.

According to the representation in FIG. 1, the presetting device 10 comprises a first handle 12 with which the basic or primary acting tensile force of the adjusting device 2 can be changed as desired or preset as required. The additional adjustment device 11 comprises in the embodiment according to FIGS. 1 and 2, a further, structurally independent handle 13, with which the setting or effect of Zusatzzeinstellvorrichtung 11 can be changed. Alternatively, however, it is also possible to operate or influence both the presetting device 10 and the additional setting device 11 with only a single handle, as will be explained below. In particular, it is possible to operate or actuate the presetting device 10 and also the auxiliary setting device 11 with a single or a central handle.

According to the embodiment in FIGS. 1 to 5, the two handles 12, 13 for a user preferably directly accessible, in particular arranged on the upper side of the board-like sliding device 1. The mechanical components of presetter 10 and adjuster 11 required for force transmission are preferably predominantly in the board-like body, i. integrated in the structure of the sliding device 1. Preferably, a housing 14 or an adequate support element is provided, which holds or guides the mechanical components of the adjusting device 2 and can be at least partially embedded in a corresponding recess in the Gleitgeräteaufbau.

In Fig. 2 is a first embodiment of the adjustment device 2 for individually changing the tension of at least one tension element 5, 6, in particular for influencing the bending stiffness of a board-like sliding device 1 is illustrated schematically. This adjusting device 2 comprises two separately executed handles 12, 13, wherein the first handle 12 is provided for changing the setting of the presetting device 10 and the second handle 13 is provided for changing the setting of the auxiliary setting device 11. The first handle 12 is designed as a rotatably mounted adjusting wheel 15 which is rotatable about a perpendicular to the top 16 of the slider 1 extending axis 17 rotatable, in particular bidirectionally. Depending on the rotational angle position or depending on the number of executed revolutions of preferably manually or without tools rotatable adjusting wheel 15, the tension in the tension elements 5, 6 is increased or decreased. Preferably, the number of executed, full revolutions of the adjusting wheel 15 is a measure of the tensile stress on at least single or single-stranded traction element 5.6. It is essential that the pretensioning device 10 normally maintains the preset mechanical tension on it, or that the basic setting of the presetting device 10 is usually carried out by the user, in particular in the open field , is not changed. Rather, a possibly required additional effect of the auxiliary setting device 11 can be switched on and off relatively promptly, as required, against the action of the presetting device 10, i. are added to the basic or presetting and subtracted. For this purpose, the additional setting device 11 is preferably connected in series with respect to the presetting device 10, preferably in series. Alternatively, however, the auxiliary setting device 11 can also act parallel to the presetting device 10, wherein when the traction effect of the auxiliary setting device 11 is exceeded, the previously prevailing pulling action of the presetting device 10 becomes inactive in comparison to the traction effect of the presetting device 10.

An advantageous embodiment of the presetting 10 includes at least one spindle assembly 18, 19 for continuous or continuous change in the tension of the at least one tension element 5, 6. The embodiment shown schematically in Fig. 2 comprises two spindle assemblies 18, 19, wherein the first spindle assembly 18 has a right-hand thread and the second spindle assembly 19 has a left-hand thread. The two spindle assemblies 18, 19 are coupled by means of a bevel gear 20, in particular via at least two bevel gears, with the setting wheel 15, in particular with its bevel gear. The bevel gear 20 causes an at least approximately perpendicular implementation between the axes of rotation of the spindle assembly 18, 19 and the axis 17 of the adjusting wheel 15 and optionally a torque adjustment or a speed ratio.

In particular, a so-called turnbuckle is performed, in which a bevel gear 20, the distance between opposing drawbar eyes 21, 22 and similar traction elements can be changed. At these synchronously adjustable drawbar eyes 21, 22 of the presetting device 10, one end of the tension element 5 or of the tension element 6 is fastened in each case. Optionally, between these drawbar eyes 21, 22 and the tension element 5, 6 mounted thereon a resilient element, for example a tension spring or a compression spring in helical form or another elastomeric plastic body is arranged. Alternatively, or in combination, the tension member 5, 6 may also be to some extent longitudinally elastic, i. be elastically stretchable and recoverable.

The bevel gear 20 preferably represents a reduction gear, whereby the user can achieve comparatively high tensile forces of more than 100 N on the tension element 5, 6 when applying a moderate operating force to the setting wheel 15. The pitch of the threads on the spindle assemblies 18, 19 is preferably selected uniformly and sufficiently low, so that the presetting device 10 is formed as a self-locking adjustment device. The presetter 10 is incorporated in at least one pull cord of the tension members 5, 6, i. the at least one tension element 5, 6 is interrupted at at least one point and the presetting device 10 is connected to the ends of the tension element 5, 6 lying closest to one another. In particular, the ends of the tension element 5 or 6 or the tension elements 5, 6 which are closest to one another are fastened to the drawbar eyes 21, 22 extending diametrically to the setting wheel 15.

In any case, the traction elements or drawbar eyes 21,22 are either approximated or distanced from each other by rotation of the adjusting wheel 15 in one of the two directions of rotation, so that the tension in at least one tension element 5, 6 varies individually, i. can be enlarged and reduced.

In the illustrated embodiment according to FIG. 2, the additional setting device 11 is formed by an actuating cam arrangement 23, which can be transferred into at least two different setting positions 24, 25 with abruptly changed or abruptly varying traction. In the case of the actuating cam arrangement 23 illustrated in FIG. 2, an inactive position of the coarse or additional setting device 11 is quasi present when the first setting position 24 is taken, while when the second setting position 25 is taken a crack is present Activation of the coarse or Zusatzininstellvorrichtung 11 takes place. With appropriate activation of the additional setting device 11, a connection or addition of the tensile or tensile force values which can be applied by the additional setting device 11 takes place to the preset values of the presetting device 10. This is achieved by a series connection between the presetting device 10 and the additional setting device 11 achieved.

The handle 13 of the actuating cam assembly 23 is formed by a lever which is ver-pivotable about an axis perpendicular to the top 16 of the sliding device 1 axis 26. At least one cam 27 of the actuating cam arrangement 23 is rotated about this axis 26 or else about a further axis coupled thereto in terms of movement. This cam 27 or eccentric disk has at least two predefined radii or a minimum and a maximum diameter with respect to the axis 26 or with respect to its axis of rotation. That is, assuming that angular position at which the minimum diameter of the cam 27 is active, the auxiliary adjuster 11 acts with minimal tension or no tension, while upon activation of the maximum diameter of the cam 27, the auxiliary adjuster 11 with maximum traction acting on at least one tension element 5, 6.

The actuating cam arrangement 23, in particular its cam 27, is preferably subjected to pressure, while the tension elements 5, 6 are subjected to tension. In particular, a mutual overlap or an overlap width 28 between overlapping end sections of the at least one tension element 5, 6, in particular of the end sections of the tension elements 5, 6, is adjustably changed via this actuating cam arrangement 23. Preferably, the actuating cam arrangement 23, in particular its cam 27, with C- or L-shaped load transfer elements 29, 30 in a mutually supporting connection, wherein each one of these load transfer elements 29, 30 to a respective facing end of the rope or band-shaped tension element 5, 6 acts. Depending on the selected setting position 24 or 25, the cam 27 positioned within the overlap width 28 or between the overlapping load-transfer elements 29, 30 effects a maximum approach or a maximum spacing between the mutually facing end sections of the at least one pull element 5, 6.

As an alternative to an actuating cam arrangement 23 for the additional setting device 11, it is also possible to provide a sliding crank mechanism, wherein by means of a rotary disc or a crank pin arrangement and at least one connecting rod articulated thereto a rotational movement is converted into a translatory movement and vice versa, so as to increase the tensile stress on the at least one tension element 5, 6 vary or change. But also winding or winding devices for the at least one tension element 5, 6 are possible, as will be explained below.

In the advantageous embodiment according to FIG. 2, the at least one tension element 5, 6 is guided in two or double-stranded fashion. Of course, it is also possible to provide only one pull cord or more than two parallel tensile cords to keep the forces acting on the tension element 5, 6 loads low and thereby its breaking or. To reduce the risk of tearing. In order to achieve this two- or multi-stranded guidance of the at least one tension element 5, 6, at least one deflection loop 31, 32 is formed in at least one of the sections 7, 8 of the gliding board body. The respective deflection loop 31, 32 can be accomplished by at least one deflecting element 33, 34, which enables the least friction guidance and direction reversal or / deflection of the at least one tension element 5, 6. These deflecting loops 31, 32 or these deflecting elements 33, 34 are in this case positioned in the mutually distanced subsections 7, 8 of the sliding device 1. The deflection elements 33, 34 may be formed by simple abutment or cable guides or be implemented by at least one rotatably mounted guide roller.

This means that in the front end portion and / or in the rear end portion of the sliding device 1 at least two tension cords are executed, which run towards the centrally or centrally positive adjusting device 2 and can be variably biased by means of the adjusting device 2 and thereby preferably jointly or synchronously and evenly loaded.

2, the additional adjustment device 11 is assigned to the first tension cord of the front and rear tension elements 5, 6, while the presetting device 10 is assigned to the second, at least approximately parallel tension cord of the front and rear tension elements 5, 6. This means that the additional adjustment device 11 acts on one of the tension cords of the tension elements 5, 6, while the pretensioning device 10 acts on the tensile strand of the tension elements 5, 6 running parallel or approximately parallel to it. The respective traction elements 5, 6 are deflected friction in the respective sections 7, 8, in particular slidably returned or fixed immovable. This means that the presetting device 10 and the additional setting device 11 can interact with regard to their pulling action, in particular in parallel but can also be connected in series, wherein they can be operated and deactivated independently of one another.

The one or more parts executed traction elements 5, 6 are in this embodiment in the mutually distanced sections 7, 8 of the slider 1 each loop-like or arcuately deflected and thereby form a total considered a self-contained pull loop, which extends over more than 50%, in particular over 60% to 90%, preferably in about 75% of the longitudinal extent of the sliding board body 1 extends.

FIGS. 3 to 5 illustrate a further embodiment of an adjusting device 2 for influencing the tension in the sliding device 1 and thus for changing the static and dynamic properties of the sliding device 1. This setting device 2 also comprises a presetting device 10 and an additional setting device 11, the same reference numerals being used for parts already described above, and the preceding descriptions being analogously applicable to identical parts with the same reference numerals.

The additional setting device 11 is in this case again formed by an actuating cam arrangement 23 which has at least one pressure-loaded cam 27 for changing the overlap width 28 between mutually facing end sections of the tension element 5, 6, in particular for changing the overlap width 28 between C, U or L-shaped load transfer elements 29, 30 at mutually facing ends of the tension element 5 and 6, respectively.

The presetting device 10 in this case again comprises a spindle arrangement 18, 19 with two counter-rotating threaded sections, which act in the manner of a turnbuckle. This spindle arrangement 18, 19 can be set in rotary motion by means of a bevel gear arrangement 20 which comprises two mutually meshing bevel gears with axes of rotation extending at right angles to each other. Depending on the direction of rotation on the bevel gear 20, the drawbars 21, 22 or adequate tension members and attached thereto ends of the at least one tension element 5, 6 approximated or distanced each other, whereby the mechanical bias in at least singularly executed tension member 5 and 6 increases or is lowered. The drawbar eyes 21, 22 or adequate traction elements can at the same time be embodied as guide elements 35, 36 for the ends of the traction element 5 or 6, in order to twist the traction elements 5 and 6 about their longitudinal axis, in particular about the axis of rotation of the spindle arrangement 18, 19 to stop. In cooperation with other, in or on the sliding device 1 or in the housing of the adjusting device 2 set, i. bewegungsstarr trained guide elements 37 is a distortion of the tension element 5 and 6 around the longitudinal axis in any case excluded even if the spindle assembly 18, 19 is already under high mechanical bias and is set in rotary motion.

These guide elements 37 or else additional guide elements can furthermore be provided in order to effect a lateral offset or a lateral deflection of the access element 5 and 6, respectively. In particular, with at least one guide element 37, a reduction in spacing between the presetting device 10 and the tensile strand of the tension element 5 or 6 running parallel thereto can be effected, as can be seen from FIGS. 3, 4. The guide elements 37 may be formed by web-like guide members and / or be implemented by hose guides, in which a rope-like tension element 5 and 6 runs.

It is advantageous if the at least one tension element 5 and 6 are designed as a so-called Bowden cable 38, wherein the actual tension element 5, 6 is formed by at least one wire rope, which is guided in an originally flexible, tubular enclosure, such as this was indicated schematically, especially in the illustration according to FIG. 3. The tubular casing for the rope-like tension element 5, 6 and optionally the rope-like tension element 5, 7 to be guided therein are integrated into the latter during the production of the sliding device 1. That the tubular casing is embedded in the desired shape or in terms of the required course and then this envelope provides a low-friction guide for the at least one, received therein or male tensile element 5 and 6, respectively. The rigidly embedded sheath of the at least one Bowden cable 38 thus represents a guide channel for a rope-like tension element 5 and 6 in the interior of the sliding board body, in particular in the lower flange of the sliding device 1.

As best seen in Fig. 4 it can be seen, the mechanical components of the presetting device 10 and the additional adjustment device 11 on a common support element, in particular within a largely closed housing 14 are arranged. This housing 14 is for the most part integrated in the sliding device 1. In opposite walls of the housing 14, in particular in the end walls openings are provided, through which the tension members 5 and 6, in particular corresponding Bowden cables 38 can be inserted into the interior of the housing 14. The housing 14 in this case has a width which is slightly smaller than the width of the sliding device 1, so that the housing 14 does not protrude beyond the side cheeks of the sliding device 1. The presetting device 10 and the additional setting device 11 are preferably arranged offset to one another in the longitudinal direction of the sliding device 1. In particular, a longitudinal offset is provided, whereby a lateral space or space gain is achieved and the components of the presetting device 10 and the additional setting device 11 structurally solid or ergonomic as possible can be performed.

It is further advantageous if the additional setting device 11, in particular its actuating cam arrangement 23 is positioned with its perpendicular axis 26 in the lateral edge region of the housing 14, as a relatively long handle 13 in the form of a lever can be performed, which within a parallel to the upper side 16 of the sliding device 1 extending plane is pivotable. Expediently, a length 39 of the lever or the handle 13 is approximately 70% to 110%, in particular approximately 80%, of the width of the sliding device 1 in that section in which the adjusting device 2 is positioned. As a result, optimal leverage can be achieved. In particular, a relatively smooth operation of the auxiliary setting device 11 is made possible and nevertheless a sufficiently large displacement for the tension element 5 or 6 can be achieved.

As best seen in Fig. 5 it can be made via the adjusting wheel 15 an individual default with respect to the stiffness and flexibility of the sliding device 1 are made. This adjustability takes as a parameter the weight of each user. For this purpose, a scale 40, in particular a weight scale, is formed on or about the setting wheel 15. By means of a display element, for example a notch, a viewing window or a pointer, the respective setting on the presetting device 10 can be checked or read. In the embodiment shown in Fig. 5, the gliding device 1 can be tuned to user weight values between 55 kg to 85 kg. Of course, other, in particular narrower or wider set value ranges can be provided. The weight setting made by way of example is 70 kg according to the displayed value. The housing 14 with the mechanical components of the adjusting device 2 mounted therein is closed at the top with a cover element 40 'in order to prevent the penetration of snow or ice. On this and partially within this cover element 40 ', the handles 12, 13 are mounted. Preferably, the scale 40 or the display element on this cover element 40 'are executed.

With the presetting device 10 can be set in conventional or average conditions for a large part of different heavy users of the sliding device 1 a favorable use behavior, in particular an ideal or harmonious as possible transition between sliding and repulsion phase. The proposed board-type gliding device 1, in particular a corresponding cross-country skiing 3, is therefore also particularly suitable for rental or for the so-called rental business, since with only one type of gliding device a plurality of different users can be optimally served. In addition, the user is allowed by the adjustability of the presetting device 10 to make a shortfall or exceeding of the manufacturer or distributor of the sliding device 1 as a rule provided as optimal setting value. This so-called "offset" can in particular be varied or individually adjusted depending on the respective ambient or snow conditions, the athletic performance and other parameters.

It is essential that by means of the additionally provided additional setting device 11, the preset value via the presetting device 10 changes abruptly, in particular abruptly and temporarily can be increased or decreased. This is particularly advantageous when the adjustment device 2 is designed on a cross-country ski 3 and the user, for example, for a longer downhill route primarily use or want to ensure the sliding properties of cross-country skis 3. In particular, he can increase the bias or bending stiffness in cross-country ski 3 by activating the Zusatzzeinstellvorrichtung 11 and thus prevent too strong bending and unwanted braking of the central or lying below the binding mounting area climbing zone better or more reliable. This conversion to a comparatively hard or rigid cross-country ski 3 is effected by a simple and special quickly settable actuation of the auxiliary setting device 11, in particular by flipping or swiveling the handle 13 in the corresponding setting position 25, as this was indicated by dashed lines. Subsequently, the user of the cross-country skis 3 can increase the flexibility of the sliding device 1 again, for example, to achieve the best possible change between climbing phase and sliding phase, when the classic cross-country technique is performed again in connection. For this purpose, it is only necessary to move the handle 13 or the lever quasi and to transfer according to the example in the setting position 24, as shown with solid lines.

The additional adjustment device 11 thus allows the user to change the rigidity of the sliding device 1 in a simple manner particularly short-term and without tools, so as to achieve an optimal sliding behavior, for example, on longer runs, even if the paired sliding devices 1, for example When cornering rather uneven loading. The achievable with such a gliding device 1, in particular with such a cross-country ski 3 performance can be increased for both relatively inexperienced recreational athletes as well as experienced users.

6 to 9, a further embodiment of the adjusting device 2 is shown, wherein the same reference numerals are again used for previously described parts and the previous descriptions can be mutatis mutandis to the same parts with the same reference numerals.

In this case, the presetting device 10 is formed by a so-called traveling nut arrangement 41. This traveling nut arrangement 41 is provided for preferably vertical or lateral deflection or deflection of the at least one tension element 5 or 6. As is known per se, the traveling nut arrangement 41 comprises an adjusting spindle 42 for a traveling nut 43 screwed onto this adjusting spindle 42. By turning the adjusting spindle 42, a relative movement, in particular a translational movement of the traveling nut 43, is thereby effected achieved along the adjusting spindle 42. In the illustrated embodiment, an axis 44 of the adjusting spindle 42 extends substantially perpendicular to the top 16 of the slider 1. Depending on the direction of rotation of this adjusting spindle 42 via their threads either an increase or decrease of the traveling nut 43 relative to the top 16 of the slider 1 and relative to Longitudinal extension of the axis 44 and thus a vertical deflection or deflection of the at least one tension element 5, 6. By this controllable arc or triangular deflection or deflection of the tension element 5 and 6 in at least one point of its tensile stress or preload is increased, whereas in the case of a preferably straight course of the tension element 5 or 6 in the area of the traveling nut 43, the tension in the tension element 5 or 6 is the lowest.

The traveling nut 43 is designed as a carrying and guiding element 45 for the at least one tension element 5 and 6, respectively. In particular, the tension element 5 or 6 can be adjusted relative to the support and guide element 45 with respect to the longitudinal direction of the tension element 5, whereby a preferably symmetrical bias in the tension elements 5 and 6 before and behind the traveling nut 43 is effected. Above all, this greatly avoids asymmetrical tensile stress conditions in the front or rear portion of the adjusting device 2 or largely prevented.

The scale 40 for displaying the set or preset via the Voreinstellvorrichtung 10 Zugspannungswerte, which then have on the flexural rigidity or on the flexibility of Gleitgerätes 1 corresponding influence, in this case by a linearly adjustable scale 40 is formed, which with the rotatable Adjusting spindle 42 is coupled motion. In this case, a gear ratio 46 is formed between the adjusting spindle 42 and the linearly adjustable scale 40 for displaying the respective setting values. The toothed or friction wheels of this gear ratio 46 and the linearly displaceable scale 40 are positioned below the cover element 40, in particular between the cover element 40 and the uppermost covering layer of the sliding device 1. As a result, the simplest possible construction and uncomplicated assembly of the adjusting device 2 is achieved. In addition, thereby the production of the sliding board body 1 is simplified.

In this embodiment too, the presetting device 10 and the additional setting device 11 can be influenced or changed independently of one another. Nevertheless, only a single or a functionally combined handle 12 for selectively actuating or changing the presetting device 10 and the additional setting device 11 is formed. For this purpose, the handle 12 is connected to the adjusting spindle 42, wherein the handle 12 is rotatable or rotatable together with the adjusting spindle 42 about the axis 44 and about a second, transverse to the axis 47 relative to the adjusting spindle 42 is pivotable or tiltable. In this case, when the handle 12 is rotated or rotated about the first axis 44, there is an influence on the presetting device 10. In contrast, when tilting or tilting this handle 12 to the other, transverse to the axis of rotation of the adjusting spindle 42 extending axis 47 influencing the Zusatzzeinstellvorrichtung 11, in particular an activation and deactivation of Zusatzzeinstellvorrichtung 11 accomplished.

In this case, this additional setting device 11 comprises an eccentric lever arrangement 48, by means of which an abrupt or coarse-step change in the tension values of the setting device 2 can be made. By means of this eccentric lever arrangement 48, an axial raising or lowering of the adjusting spindle 42 is achieved. That is, when taking the first setting position 24, the adjusting spindle 42 is in the rest or initial position shown in Fig. 8, while taking the second setting position 25, the adjusting spindle 42 in the axial direction, that is in the direction of the axis 44, relative is raised to the top 16 upwards and thereby the traveling nut 43 and the support and guide element 45 for the at least one tension element 5 and 6 can be jumped or impulsively raised, whereby the tension in the tension elements 5, 6 increases relatively abruptly. The adjusting spindle 42 is thus not fixed in the axial direction, but the adjusting spindle 42 remains relatively adjustable in a bearing arrangement 49 for the lower end face of the adjusting spindle 42 in the axial direction in the axial direction. The bearing assembly 49 is preferably designed as a sliding or guide bushing for the adjusting spindle 42. That is, the adjusting spindle 42 is not fixed in the axial direction and by means of the eccentric lever assembly 48 to a certain extent, i. can be raised and lowered within predefined limit stops. The eccentric lever arrangement 48 includes, as is known per se, at least one cam 27 or the axis 47 facing the end of the handle 12 is elliptical or cam-like, so that in the in FIG. 8, the adjusting spindle 42 is maximally lowered into the Gleitgeräteaufbau, while the adjusting spindle 42 is almost pulled out when taking the second setting position 25 from the slider 1 and thus the at least one tension element 5 or 6 additionally off or deflects. When taking the second setting position 25 or when changing from the first setting position 24 to the second setting position 25, the axis 47 of the handle 12 preferably extends transversely to the longitudinal direction of the sliding device 1 and substantially parallel to the top 16 of the sliding device. 1

10, a further embodiment of the adjusting device 2 is illustrated, wherein the same reference numerals are used for previously described parts and the preceding descriptions can be mutatis mutandis to the same parts with the same reference numerals.

Here, two diametrically to the adjustment device 2 extending tension elements 5, 6 are formed, which extend starting from the adjusting device 2 on the one hand in the front portion 7 of the sliding device 1 and on the other hand in the rear portion 8 of the sliding device 1. For example, in the rear section 8, the tension element 5 forms a deflection loop 31. This means that the first pulling element 5 is guided starting from the adjusting device 2 in the rear section 8 and / or in the front section 7 and there forms a deflection loop 31 without interruption, via which the tension element 5, starting from the rear or front portion 7, 8 is returned to the adjustment device 2 again. This means that the rope-shaped tension element 5 is preferably designed to be continuous or in one piece and, in the exemplary embodiment shown, forms two tension strands which act essentially in parallel. A first tensile strand runs starting from the adjustment device 2 in the direction of the rear section 8 and / or in the direction of the front section 7, and the second tension strand formed by the deflection loop 31 and running essentially parallel to the first tension strand is guided back to the adjustment device 2.

The preferred rope-shaped tension member 5 thus forms a train loop, the deflection loop 31 is formed in at least one end portion of the sliding device 1. The deflection loop 31 is defined by means of two circular or arcuate deflection elements 33, 34 in cross section, wherein these multiple deflection elements 33, 34 can also be combined to form a single deflection element. Also within this deflection loop 31, the tension element 5 is preferably deflected slidable or relatively adjustable. The deflection elements 33, 34 can thus also be formed by rotatably mounted guide rollers for the tension element 5.

The front portion 7 may be similar to the rear portion 8 executed with respect to the guidance or anchoring of the forwardly extending tension member 6. According to the illustrated embodiment, the anchoring or fixing the tension element 6 in the front portion 7 but also by a rigid fixation of at least one end of the tension element 6 done. In particular, at least one anchoring element 50, for example a holding plate or other load distribution means, is integrated or embedded in the interior of the sliding device 1. At this anchoring element 50, which is rigidly integrated in the gliding board body, the ends of the two-stranded tension element 6 are fastened or a return loop of the tension element 6 is fastened to this anchoring element 50 in a motion-stable manner. This attachment or anchoring can be done either rigidly or with the interposition of an elastic resilient spring element, for example using an elastomeric buffer or a spiral spring assembly 17/52 Austrian Patent Office AT506 545B1 2012-05-15.

In the embodiment according to FIG. 10, on the one hand, an uninterrupted return of the first tension element 5 is converted back to the setting device 2. On the other hand, an arrangement is selected in which the further tension element 6 is indeed performed double- or two-stranded, but the opposite ends of the adjusting device 2 of these two tension cords in the front section 7 are each anchored fixed. According to this embodiment, therefore, both tension elements 5, 6 each extend in a double-stranded manner, it also being possible to guide the tension elements 5, 6 in a multi-stranded manner in order to correspondingly reduce the forces to be absorbed per tensile strand. This means that the tension elements 5, 6 can also be guided in the manner of a so-called pulley or can be deflected several times.

The presetting device 10 is formed in this embodiment by a drum assembly 51 for fine-step or continuous winding and unwinding of the at least one tension element 5, 6. In particular, a winding drum 52 is formed, which is rotatably mounted about a perpendicular to the upper side 16 of the sliding device 1 extending axis 53. At this preferably designed as a double coil winding drum 52, the winding drum 52 facing ends of the tension element 5 and 6 are attached or placed. As can be seen in FIG. 10, the ends of the diametrically spaced-apart tension elements 5, 6 can be placed on diametrically opposite sections on the winding drum 52 or on their respective winding coil halves. The at least two Wickespulenhälften are preferably synchronously rotatable about the common axis 53. This ensures that when turning the winding drum 52 in a first direction of rotation both tension elements 5, 6 stretched or wound, while rotational direction in the opposite direction both tension elements 5, 6 are unwound from the at least one winding drum 52, so that the tension is reduced in the tension elements 5, 6. In the case of multiply formed winding drums 52, these generally have uniform diameters. To achieve a transmission ratio and to achieve different bias voltages in the front or rear section 7, 8, the coil or winding drum diameter but also be different.

The drum assembly 51 with the at least one winding drum 52 may be formed by any known from the prior art ratchet winding device 54, which allows a fine-step change in the tension in the at least one tension element 5, 6. The advantage here is a drum assembly 51 or a ratchet winding device 54, which allows the finest possible change in the tensile stress, in particular an individual increase and a controlled release of the tensile stress in the tension elements 5, 6 allowed. Such drum assemblies 51 or ratchet winding devices 54 for band or rope-shaped tension elements 5, 6 are known from the prior art in various designs.

The corresponding drum assembly 51 or ratchet winding device 54 can be actuated via a known setting wheel 15. Depending on the direction of rotation selected by the operator on the setting wheel 15, the tension of this presetting device 10 is either increased or decreased. However, the ratchet winding device 54 can also be designed such that only a unidirectional rotation of the setting wheel 15 is made possible, whereby an increase in the tension in at least one tension element 5, 6 takes place. By axial adjustment of the setting wheel 15, the previously constructed tensile stress can then be reduced or, as a result, the at least one tension element 5, 6 can be rapidly loosened or released relative to the winding drum 52.

The thumbwheel 15 has wells or knobs known per se for comfortable and at the same time powerful operation of the presetting device 10. In order to increase the torque which can be applied via the presetting device 10 or to increase the tensile or winding force of the drum arrangement 51, in particular the ratchet winding device 54, a lever-like handle 12 can be embodied on the setting wheel 15. This lever-like handle 12 is mounted tiltable or foldable on the setting wheel 15. In particular, the handle 12 is pivotable about a pivot axis 55 extending transversely to the axis 53 of the adjusting wheel about a pivot axis 55 extending across the axis 53 of the adjusting wheel. This pivot axis 55 for the lever-like handle 12 is arranged in the outer edge portion of the adjusting wheel 15, as was illustrated schematically in Fig. 10. In particular, a maximum distance between the axis 53 and the pivot axis 55 extending transversely thereto is selected. In the inactive state of the handle 12 shown in solid lines in FIG. 10, the handle 12 extends transversely across the setting wheel 15, wherein the handle 12 preferably extends through the center point of the setting wheel 15. A length of the handle 12 corresponds approximately to the diameter of the setting wheel 15th

By pivoting and folding this lever-like handle 12 in the active position shown in dashed lines then the leverage on the winding drum 52 and on the ratchet winder 54 can be significantly increased. In particular, the lever arm between the axis 53 and the end remote from the handle 12 is significantly increased by moving the handle 12 in the active position shown in dashed lines. The torque which can be provided by means of the drum arrangement 51 or the ratchet winding device 54 or the winding force that can be applied to the at least one tension element 5, 6 can thereby be increased significantly if necessary. Nevertheless, a compact design of the operating or actuating members of the presetting device 10 is made possible after the handle 12 can, if necessary, be transferred between a compact inactive position and a comparatively projecting active position. For the quickest possible operation of the presetting device 10, the setting wheel 15 is preferably taken directly and rotated accordingly. As soon as higher torques are required or to achieve the most ergonomic operation when wearing gloves, then the handle 12 can be pivoted into the illustrated in dashed lines active position.

The additional setting device 11 or a so-called "overdrive". to the sudden change in the tensile stress in the at least one tension element 5, 6 is in this case formed by a lever clamping element 56. This lever clamping element 56 is provided for the fastest possible approach or increase in distance between mutually parallel tension elements 5, 6 and Zugelementsträngen. In the illustrated embodiment, the lever clamping element 56 comprises a control bar 57 which is mounted pivotably about a central axis 58 as needed. In the embodiment according to FIG. 10, this axis 58 extends substantially perpendicular to the upper side 16 of the sliding device 1. In the opposite end sections of this adjusting bar 57, receiving means 59, 60 are formed for the tension members 5, 6 guided in a double-stranded manner according to the illustrated embodiment. These receiving means 59, 60 for the tension elements 5, 6 may be formed, for example, by cuts, eyes or by finger or bolt-like guide elements in the distal end portions of the adjusting bar 57. This receiving means 59, 60 cause a positive guidance or forced coupling between the adjusting bar 57 and the tension elements 5, 6. By pivoting this adjusting bar 57, an approximation or distancing between the parallel tensile strands of the tension elements 5 and 6 is achieved, so either a Increase the tension or tensile force or lowering the tension or tensile force in the tension strands of the tension elements 5 and 6 to achieve. The pivoting of the adjusting bar 57 by means of the handle 13, which preferably represents a lever extension to the adjusting bar 57. Such a lever clamping element 56 comprising the adjusting bar 57 and the handle 13 permits a particularly rapid or abrupt change in the tension values introduced by means of the at least one pulling element 5, 6 into the sliding device 1.

The handle 13 designed as a lever preferably represents an extension of the adjusting bar 57 in order to obtain a powerful pivoting of the adjusting bar 57 and thus a sufficiently intensive approximation or distancing of the tensile strands of the at least one pulling element 5, 6 under tension.

In the first setting position 24 shown in FIG. 10, the lever clamping element 56 assumes an inactive position in which there is no or only a marginal influence on the two tension cords of the at least one tension element 5, 6. When pivoting the handle 19/52 Austrian Patent Office AT506 545B1 2012-05-15 13 in the second setting position 25, the two substantially parallel tensile strands of the tension element 5 and 6 are approximated, whereby the tension in the tension element 5 and 6 increases significantly , At least in the active setting position 25 a locking or fixing the handle 13 is possible. A plurality of intermediate positions can also be provided between the first setting position 24 and the second setting position 25, with which the action of the lever clamping element 56 or the additional setting device 11 can be graduated to a certain extent or made variable. This coarse or additional setting device 11 also causes the tension preset by means of the presetting device 10 to be abruptly increased or lowered by actuating or activating or deactivating the auxiliary setting device 11. This additional adjustment device 11 can thus also be referred to as a so-called "overdrive element". be designated.

The lever clamping element 56 may further comprise at least one support or guide element 61, 62, by which a triangular or arcuate deflection of the at least one tension element 5, 6 is ensured in contrast to a rectilinear extent. These support or guide elements can be formed by tubular sleeves, by web-like walls or by other elements for the slidable support of the tension elements 5, 6. Between two such support or guide elements 61, 62, the at least one tension element 5, 6 can be deflected laterally and thus its tension can be changed to a corresponding extent.

In Fig. 11, a further embodiment of the adjusting device 2 is illustrated, wherein the same reference numerals are used for previously described parts and the foregoing description parts are mutatis mutandis to the same parts with the same reference numerals transferable.

Here, the presetting device 10 is formed by a further embodiment of a ratchet winding device 54, wherein in this variant, a rotation axis 63 of the winding drum 52 extends at least approximately parallel to the top 16 of the slider 1 and substantially transverse to the longitudinal center axis of the sliding device 1. In particular, a quasi-lying winding drum 52 is provided, on which at least one preferably band-shaped or rope-shaped tension element 5, 6 can be wound up and unwound. Preferably, a leading in the front portion 7 tension member 6 and a leading in the rear portion 8 traction element 5 on a common winding drum 52 is double-layered or unwound, as shown in FIG. 11 can be seen. Alternatively, it is of course also possible to provide only one tension element 6, which is guided either in the front or rear portion 7, 8 of the board-like sliding device 1.

This ratchet winding device 54 comprises - as known per se - a reverse rotation lock 64, for example consisting of a toothed disc in combination with a spring-loaded pawl to prevent unintentional turning back of the winding drum 52 and to achieve a maintenance of the set tension. The handle 12 of the ratchet winding device 54 is formed by a lever which is rotatably mounted about the rotation axis 63 of the winding drum 52 and in conjunction with a toothed disc or the reverse rotation lock 64 controlled co-rotation of the winding drum 52 and thus an on-demand increase in the tensile stress in at least a tension element 5, 6 allows.

The ratchet means for unidirectional rotary motion coupling between the handle 12 and the winding drum 52 comprises in a conventional manner a spring-loaded pawl 65, which can be put into engagement with the toothed disc and disengaged. According to the embodiment of FIG. 11, the lever-like handle 12 is rotated clockwise to increase the tension, wherein the winding drum 52 is set in rotational motion, an unintentional reverse rotation is prevented by the reverse rotation lock 64. By means of the ratchet means, the handle 12 can be transferred again into the initial position shown, without causing the tension in the at least one tension element 5 and 6 is lowered. For controlled release, the reverse rotation lock 64, in particular 20/52 Austrian Patent Office AT506 545B1 2012-05-15 transferred their pawl in an inactive position and lowered the tension by turning the handle 12 and the winding drum 52 in the counterclockwise direction. Such a ratchet winder 54 is known in the art in a variety of forms. For example, e.g. the arrangement of the pawl 65 on the lever-like handle 12 is a common measure to be able to perform by means of the handle 12 a ratchet-like movement.

According to the illustrated embodiment, at least the lower portion of the ratchet winder 54 may be disposed in a recess 66 in the top 16 of the slider 1. As a result, the most compact possible construction of the adjusting device 2 is achieved.

The additional adjustment device 11 is again formed by an eccentric lever arrangement 48 which comprises at least one actuating cam arrangement 23. In the illustrated embodiment, three adjustment positions 24, 25, 25 'are provided, wherein in a first adjustment position 24, the Zusatzinstellvorrichtung 11 is inactive or nearly inactive, while taking a second or third setting position 25, 25', the tension element 6 laterally, in particular deflected vertically and thus the tension of the same abruptly, ie is increased spontaneously. The eccentric lever arrangement 48 is pivotable about an axis 67 extending transversely to the longitudinal center axis of the sliding device 1 and substantially parallel to the upper side 16 of the sliding device 1. The individual adjustment positions 24, in particular the active adjustment positions 25, 25 'are maintained by pivoting the actuator cam assembly 23 in corresponding Übertotpunktsteilungen so that separate locking mechanisms for maintaining the respective desired setting position 25, 25' are unnecessary and a particularly rapid transfer to another setting position 24 or 25 or 25 'is possible.

In the illustrated embodiment, the tension element 6 is deflected by the eccentric lever assembly 48 in a recess 68 in the top 16 of the sliding device 1. At least a portion of the eccentric lever assembly 48 is disposed within this recess 68. The various adjusting cams or shelves of the eccentric lever assembly 48 urge the tension member 6 more or less in the recess 68 in the top 16 of the slider 1. The relative adjustment of the lever-like handle 13 along the longitudinal axis of the slider 1 allows a powerful, ergonomic and rapid Actuating the Zusatzinstellstell 11. In particular, within a few seconds, preferably within less than 5 seconds, the Zusatzzstellvorrichtung 11 between a first adjustment position 24, in particular between the inactive position, and at least a second setting position 25 or 25 ', ie an active position, be transferred alternately.

FIG. 12 illustrates a further embodiment of the adjusting device 2 for influencing the flexibility or stiffness of a board-like sliding device 1, wherein the same reference numerals are used for previously described parts and the preceding description parts are mutatis mutandis to the same parts with the same reference numerals ,

The presetting device 10 is in this case formed by a ratchet buckle 69, with which a finely graded or almost continuous change and presetting of the desired tensile stress in at least one tension element 5 can be achieved. The ratchet buckle 69 comprises - as known per se - a ratchet lever 70, which represents the handle 12. This ratchet lever 70 is provided at one end with a substantially arcuate toothing 71 and about an axis transverse to the longitudinal direction and substantially parallel to the upper side 16 of the sliding device 1 extending axis 72 pivotally. The toothing 71 of the ratchet lever 70 is in mesh with a toothed belt 73. By pump-like pivoting of the handle 12 or by an alternating forward and backward movement of the ratchet lever 70, the toothed belt 73 is moved linearly, in particular relative to the support body 74 of the ratchet buckle 69 and thus also moved relative to the sliding device 1. A spring-loaded pawl 75 prevents unintentional sliding back of the thus selectively biased toothed belt 73 or an unwilling release of the 21/52 Austrian Patent Office AT506 545B1 2012-05-15

Tensile stress in the toothed belt 73, which is connected to the tension element 5. In the illustrated embodiment, the tension in the tension element 5 is increased by turning the ratchet lever 70 in the counterclockwise direction. By pump-like forward and backward pivoting of the ratchet lever 70 while the tension in the tension element 5 can be individually increased or changed.

The ratchet buckle 69 comprises at least one release lever 76, upon actuation of which - for example, in a clockwise operation - the pawl 75 is deactivated and a jerky reduction of the tension in the tension element 5 occurs. Optionally, the ratchet buckle 69 may also include a reset lever 77, as indicated schematically by dashed lines. With such a reset lever 77 then a metered release of the tensile stress in the tension element 5, in particular a controllable, stepwise provision for one tooth or several teeth on the toothed belt 73 is possible.

The ratchet buckle 69 may be implemented in accordance with all known from the prior art embodiments. In particular, any known from the prior art pump or ratchet buckles 69 can be used to achieve at least a metered increase in the tensile stress in the tension element 5 in combination with at least one toothed belt 73. According to a development of this ratchet buckle 69, a metered or controllable release of this tension can be made via the ratchet buckle 69. Such embodiments are known from the prior art in numerous embodiments. It therefore need not be discussed in more detail on the corresponding embodiments.

The additional adjustment device 11 is in this case again formed by an eccentric lever arrangement 48, which makes it possible to take at least two different adjustment positions 24, 25 or 25 '. The actuating cam arrangement 23 has at least one positioning cam with at least two adjusting cams which are spaced differently from their pivot axis 67.

For abrupt change in the tensile stress on at least one tension element 5, 6 -example according to the tension element 5 - the handle 13 of the eccentric lever assembly 48 is pivoted either in the longitudinal direction of the sliding device 1 forward or backward. Depending on the pivot position of the handle 13, either the first, inactive adjustment position 24 or at least one further, active adjustment position 25 or 25 'is activated. In this embodiment, the traction element 5 is deflected when taking an active setting position 25 or 25 'in the vertical direction to the top 16 of the slider 1 upwards, in particular distanced from the top 16 of the slider 1 further and thus increases the tensile stress in the tension element 5 abruptly. By means of at least one fixedly connected to the gliding device 1 deflecting or guide element 33x, 37 for the tension element 5 and the toothed belt 73, a relatively striking off or deflection of the elements under tension can be achieved, so that the effect of Zusatzzeinstellvorrichtung 11 at Intake of their active position is sufficiently intense.

Maintaining the settings selected by the user in each case, in particular the active positions 25 or 25 ', is again preferably carried out by pivoting the adjusting cam arrangement 23 into corresponding over-center positions, so that additional locking devices are not required. Optionally, it is also possible to manually assign to the handle 13 and the actuating cam assembly 23 to be activated and deactivated locking devices to ensure a secure under all operating conditions maintaining the respectively desired adjustment position 24, 25 and 25 '.

The adjusting cam arrangement 23 and its axis 67 are in this case at least partially disposed in a recess 68 in the upper side 16 of the sliding device 1, so that the most compact possible construction of the auxiliary setting device 11 is achieved.

FIGS. 13 to 15 show a further embodiment of the adjusting device 2 consisting of a presetting device 10 and an auxiliary setting device 11 for changing the static and dynamic bending properties of a board-type sliding device 1 schematically illustrates. For parts already described above, the same reference numerals are used and the preceding descriptions are mutatis mutandis to the same parts with the same reference numerals transferable.

According to the schematic illustration in FIG. 13, a band-shaped tension element 5 is provided, which is arranged predominantly in the lower flange of the sliding device 1, in particular below the neutral fiber thereof. In this case, the tension element 5 extends from the tip or blade section of the gliding device 1 in the direction of the rear end section 8 of the gliding device 1. In the middle section of the gliding device 1 or in its mounting region for the binding device 9, the tension element 5 is uninterrupted, i. running continuously. In the blade area or in the front section 7 of the sliding device 1, the band-shaped tension element 5 is fixed. In the rear section 8, the band-shaped tension member 5 is coupled for movement with the adjusting device 2. In the section between the front section 7 and the rear section 8, the band-shaped tension member 5 is slidably movable. In particular, the tension member 5 extends between the front and rear portion 7, 8 within the structure of the sliding device 1 and is the tension element 5 in this intermediate portion freely slidably guided.

The adjusting device 2 comprising the auxiliary setting device 11 and the presetting device 10 is positioned according to this embodiment in the rear section 8 of the sliding device 1. By activating the presetting device 10 or the auxiliary setting device 11 as necessary, the mechanical preload in the lower belt of the sliding device 1 is changed as required within certain limits and the stiffness and the usage behavior of the sliding device 1 are influenced accordingly.

Of course, it is also possible to position the adjusting device 10 in the front section 7 or to arrange immediately before the binding device 9.

In the embodiment according to FIGS. 14, 15, the additional setting device 11 is again formed by a lever clamping element 56, which comprises a lever-like handle 13 for operation or actuation of the adjuster unit 11. This lever clamping element 56 is pivotable about a substantially parallel to the top 16 and transverse to the longitudinal extent of the sliding device 1 extending axis 78, in particular tiltably mounted. This lever clamping element 56 is thus designed as a rocker arm 79 which is pivotally mounted about the axis 78. To maintain the active position of the lever clamping element 56, the rocker arm 79 is folded over, i. pivoted into an over-center position, as can be seen by way of example from FIG. The rocker arm 79 is preferably designed fork-shaped, wherein the handle 13 is formed by the so-called stem of the fork-shaped rocker arm 79. The two forks of the rocker arm 79 preferably take between the band-shaped tension member 5. The tension element 5 is connected to variable longitudinal positions of the forks firmly with the rocker arm 79. By moving the rocker arm 79 into the active position 25 shown in FIGS. 14 and 15, the tension in the tension element 5 is markedly increased, in particular abruptly, at least for a specific or user-selected period of time.

In the embodiment according to FIG. 14, the presetting device 10 for the fine-grade change of the tension in the tension element 5 is formed by an adjusting spindle 79 '. This adjusting spindle 79 'is adjusted by rotation of the handle 13 about its longitudinal axis along the handle 13 and longitudinally to the rocker arm 79. The remote from the handle 13 end of the adjusting spindle 79 'is connected to the tension element 5. As a result, different default settings for the tensile stress of the tension element 5 are achieved. In particular, the adjusting spindle 79 'is more or less screwed into the handle 13 when the handle 13 is rotated about its longitudinal axis. At the same time, the handle 13 is a component of the rocker arm 79, via which the auxiliary setting device 11 can be transferred to different operating positions, in particular into at least one active setting position 25, as shown by way of example in FIGS. 14, 15. For inactivating the inactive setting position 24, this rocker arm 79 is pivoted over its dead center position, for example, pivoted about 180 °, whereby the tension in the tension element 5 abruptly decreases or the Tension element 5 is present without tension and is completely relaxed.

As best seen in Fig. 15, the tension member 5 is guided in a guide channel 80 in the interior of the sliding board body. The guide channel 80 is preferably formed at least largely below the neutral zone of the sliding device 1. As a result, the tension element 5 has the greatest possible effect on the tension conditions in the lower belt of the sliding device 1. An outlet or entry opening 81 for the tension element 5 is preferably formed in the vicinity of the adjusting device 2. This outlet or inlet opening 81 for the tension element 5 preferably has rounded transition regions, in order to achieve as wear-free as possible a transfer of the tension element 5, starting from the guide channel 80 in the direction of the upper side 16 of the sliding device 1.

According to the embodiment of FIG. 15, the presetting device 10 comprises a plurality of individually selectable coupling points 82 to 84, which are spaced apart in the longitudinal direction of the rocker arm 79. By individual selection of a coupling point 82, 83 or 84, the tension in the tension element 5 can be preset as needed. Preferably, the tension element 5 via these coupling points 82 to 84 without tools on the rocker arm 79 can be fastened, in particular latched to it and thus in terms of tension briefly influenceable. The coupling points 82 to 84 may be performed in the manner of a rack, which allows the trouble-free hooking of the associated end of the tension element 5. In particular, this presetting device 10 may be designed in the manner of a toothed strip and the rocker arm 79 may be designed in the manner of a tensioning buckle, as is known from tensioning devices for shoes, in particular in ski boot buckles.

In Fig. 16, a further embodiment of the adjusting device 2 is shown, wherein the same reference numerals are used for previously described parts and the previous descriptions are mutatis mutandis to the same parts with the same reference numerals transferable.

The presetting device 10 in this case again comprises a ratchet winding device 54 for the first end of the tension element 5. This ratchet winding device 54 has an adjusting wheel 15 as an actuating member. The axis 17 of the adjusting wheel 15 runs perpendicular to the upper side 16 of the sliding device 1. Depending on the angular position or depending on the number of revolutions of the adjusting wheel 15 carried out different Zugspannungswerte be set. The respective tensile or preload values of the presetting device 10 are visualized by displaying suitable values on the scale 40 or on a corresponding control window. The displayed values for the respective prestress or stiffness of the sliding device 1 are preferably represented by weight values which represent the usually optimum or the ratios between user weight and the respective rigidity of the sliding device 1 considered by the producer to be the most expedient.

By means of, for example, concentric with the setting wheel 15 arranged release button 85, the preset value of the presetting device 10 is reset, i. E. reset or reset to zero. This means that by pressing the release button 85, the bias in the tension element 5 is either greatly reduced or completely eliminated by the ratchet winder 54, in particular the winding drum 52 is switched to free rotational mobility.

The additional adjustment device 11 is mounted coaxially to the axis 17 of the presetting device 10 in this embodiment. In particular, the axis of rotation of the presetting device 10 coincides with the axis of rotation of the additional setting device 11.

The second free end of the looped in the slider 1 traction element 5 is connected to the additional adjustment device 11. The handle 13 of the additional adjustment device 11 is designed as a hub 86. By means of this turntable 86, either a separate winding drum 52, an adjusting cam arrangement, an eccentric lever arrangement or a lever clamping element is actuated in order to increase and decrease the tension values of the setting device 2 in a pulse-like manner to achieve, as described above. A diameter or an effective force arm of the rotary disk 86 of the auxiliary setting device 11 is preferably larger than a diameter or an effective force arm of the setting wheel 15 of the presetting device 10. The auxiliary setting device 11 is spontaneously activated, independently of the preset values on the presetting device 10 if required - and deactivated.

In Fig. 17, another embodiment of the adjusting device 2 is illustrated, wherein the same reference numerals are used for previously described parts and the preceding descriptions are mutatis mutandis to the same parts with the same reference numerals transferable.

The presetting device 10 in this case comprises a further embodiment of a ratchet winding device 54. This ratchet winding device 54 is designed in the manner of a Umschaltknarre 87. At the output of this Umschaltknarre 87, in particular at its winding element or winding drum 52, an end portion of the tension element 5 is placed or fastened. By pressing the Umschaltknarre 87, in particular via the handle 12, the tension element 5 is either up on the winding drum 52 or unwound, so as to change the tension in the tension element 5 as needed. By means of a switching element 88, the freewheeling or pulling direction of the Umschaltknarre 87 can be changed and thus the bias in the tension element 5 either increased or lowered as needed. This presetting device 10 makes it possible to set a specific pretension in the tension element 5 in order to achieve a sliding device 1 which is as well adapted to the respective conditions and / or the respective weight of the user.

The additional adjustment device 11 in this case again comprises a rapidly operable lever clamping element 56 to which the second, free end of the tension element 5 is attached. 17, the additional adjustment device 11 has no zugkrafterhöhende effect on the tension element 5. In contrast, the tension element 5 is in pivoting the lever clamping element 56 in the shown in dotted lines, active adjustment position 25 in addition to a certain extent biased or increased the tensile effect in the tension element 5 by a predetermined value.

In this second, active setting position 25, the lever clamping element 56 can be held automatically by utilizing a so-called over-center locking, as indicated by dashed lines. Optionally, additional, manually activated and deactivated locking mechanisms can be provided. The lever clamping element 56 is pivotable about an axis 78 extending vertically to the upper side 16. End stops 89, 90 define or limit the first, inactive setting position 24 and the second, active setting position 25 of the lever clamping element 56. By means of a scale 40, the user of the setting device 2 is shown the respective operating mode or the respective state of stress on the additional setting device 11.

18, 19, a further embodiment of the adjusting device 2 is illustrated, wherein the same reference numerals are used for previously described parts and the foregoing description parts can be mutatis mutandis transferred to like parts with the same reference numerals.

In this case, the presetting device 10 in turn comprises a spindle arrangement 18, which can be set by means of a ratchet drive 91 in a bidirectional bidirectional rotary motion. In particular, the ratchet drive 91 with the spindle assembly 18, which has opposite spindle drives, motion-coupled. That is, over the ratchet drive 91 either an approximation or a distancing of the example, as threaded pins 92, 93 executed ends of the tension element 5 is effected. At least one thrust bearing 94, 95 for the spindle arrangement 18 makes possible a rotational movement of two threaded bushes 96, 97 which are coupled with the ratchet drive 91 in a rotational movement and which are linked to the threads 92, 93 via left or right sides Right-hand thread are coupled. In the axial direction, the spindle assembly 18 via the thrust bearing 94, 95 fixed immovably. The ratchet drive 91 is preferably integrated in the interior of the sliding device 1, in particular in a housing 14 of the adjusting device 2 and is actuated from the outside via the handle 12. This handle 12 protrudes preferably from the top 16 of the slider 1 up. The pivot axis of the ratchet drive 91 and the handle 12 extends substantially parallel to the longitudinal direction and substantially parallel to the top 16 of the slider 1. Preferably, the axis of rotation of the switchable ratchet drive 91 and the axis of rotation of the spindle assembly 18 are concentric or these axes are identical.

According to an advantageous embodiment, the active or pulling direction of the ratchet drive 91 can be reversed by turning the handle 12 about its longitudinal axis. That is, by rotating the handle 12 about its longitudinal axis, the direction of rotation of the spindle drive 18 can be reversed so that an increase in the pulling action of the presetting 10 is made possible by pumping movement in the first operating position, while by transferring the handle 12 in the second operating position and by Pump-like operation of the handle 12 a controlled or sensitive reduction of the tension in the tension element 5 is made possible. Corresponding ratchet drives 91 are known from the prior art, it is thus not closer to the corresponding technical implementation details, such as. on pawls, gears, switching elements and the like.

By means of the additional setting device 11, in turn, an abrupt or sudden deflection or deflection of the tension element 5 is accomplished, thereby achieving a spontaneous change in the rigidity of the sliding device 1. The handle 13 of the additional adjustment device 11 is called a push button or "push button". executed. To maintain the active setting position 25 of the handle 13 and an actuated via the handle 13 plunger 98 is associated with a locking mechanism 99. This locking mechanism 99 ensures that the plunger 98 and the handle 13 in user-initiated selection of the active setting position 25 in this active position - as shown in dotted lines - remains until the locking mechanism 99 is actuated or deactivated again. The locking mechanism 99 thus has two selectively selectable, stable operating states, wherein when taking the active operating state, a lateral deflection or deflection of the at least one tension element 5 takes place. The locking mechanism 99 is preferably carried out in the manner of a ballpoint pen mechanism for transferring a ballpoint pen refill in writing position or standby position. Such locking mechanisms 99 or ballpoint pen mechanisms are known from the prior art, it is therefore not discussed in more detail on their technical details.

An actuating direction of the handle 13 preferably extends substantially perpendicular to the top 16 of the sliding device 1. Preferably, the handle 13 is designed such that it can be operated by foot or by pressing with the hand or the fingers of the user of the sliding device. 1 can be operated or switched. As a result, a powerful or intensive and maximum spontaneous activation and deactivation of Zusatzzeinstellvorrichtung 11 is possible. By successive actuation of the preferably linearly adjustable handle 13 while an alternate transfer of the plunger 98 in the inactive adjustment position 24 and the active adjustment position 25 is achieved.

Guiding or guiding elements 37 can contribute to a striking deflection or deflection of the tension element 5 and thus ensure a sufficiently effective additional setting device 11.

The preferably designed as a rope tension element 5, in particular its soul, is preferably designed as a plastic-coated wire rope, which thus can be performed as low friction and tear resistant.

Preferably, a scale 40 is formed, via which the respective setting of the presetting device 10 can be monitored or monitored. The respective state of the 26/52 Austrian Patent Office AT506 545B1 2012-05-15

Zusatzzstellvorrichtung 11 can be detected or detected in a simple manner on the position of the handle 13, for example, based on the height of the plunger 98, starting from the top 16 of the sliding device 1 immediately.

In Fig. 20 is shown as a particularly expedient embodiment of the board-like sliding device 1, a cross-country ski 3 in a highly simplified, schematic side view. The preceding descriptions are mutatis mutandis to the same parts with the same reference numerals transferable. Such cross-country skis 3 have, as is known, in an unloaded from the body mass of the user resting state a bias height 4 to the extent of a few centimeters. At the top 16 of the cross-country skiing 3 a suitable for practicing cross-country skiing binding device 9 is mounted. This binding device 9 extends approximately within a shoe contact zone 100 on the upper side 16 of the sliding device 1. A rear supporting device 101 of the binding device 9 should as far as possible avoid unwanted deviation movements of the respective sports shoe.

The underside of the cross-country ski 3 is usually divided into three zones. In the front and rear section 7, 8 of the sliding device, the sliding zones 102, 103 are formed on the underside thereof, which are to ensure the best possible sliding behavior with respect to the respective ground, in particular with respect to snow and ice.

Between the front and rear sliding zone 102, 103, a climbing aid zone 104 is provided, via which a Rückgleithemmung the cross-country ski 3 is to be achieved. As soon as this climbing aid zone 104 is in contact with the ground, in particular with snow or ice, slipping back of the cross-country ski 3 is prevented as far as possible. The climbing aid zone 104 can be designed as a scale or climbing wax zone. As soon as the user or athlete has sufficiently reduced the pretensioning height 4 of the cross-country ski 3 by corresponding weight load and consequently the climbing aid zone 104 comes into increased contact with the ground, a repelling effect or an accompanying forward movement can be achieved. An optimal change or switching process between effective sliding zones 102, 103 and effective climbing aid zone 104 is thus desirable for optimum locomotion or for the practice of classic cross-country skiing technique.

The adjusting device 2 comprising the presetting device 10 and the additionally formed additional setting device 11 now takes these requirements into account. In particular, a basic adjustment of the flexibility or bending behavior of the cross-country ski 3 is made via the presetting device 10. The preset by means of the preset 10 bending stiffness curve can then be changed abruptly by the Zusatzzeinstellvorrichtung 11, if necessary, in particular by a certain value or by a certain percentage, for example by 30%, relatively promptly increased and decreased.

According to an advantageous embodiment, the deflecting element 105, 106 may be associated with the at least one tension element 5, 6 to improve its effectiveness or influence on the bending characteristic. This deflection element 105, 106 causes the tension element 5, 6 to be deflected with respect to a straight line, i. does not run straight, but has at least one defined bending or bending point. In particular, the tension element 5, 6 is deflected by means of the deflecting element 105, 106 or buckled in comparison to a straight line, so that it runs either arcuately or virtually kinked. In any case, the at least one tension element 5, 6 undergoes a change of direction or a deflection of the respectively acting tensile forces by means of at least one deflecting element 105, 106. In conjunction with the tension exerted by the adjusting device 2 on the at least one tension element 5, 6, the at least one tension element 5, 6 endeavors to be converted into a position as rectilinear as possible, that is to compensate for the kink or the deflection. Thus, the rigidity or the bending characteristic is influenced particularly strikingly by the tension element 5, 6 deflected at least once in its pulling direction. In particular, it can be achieved that the front and / or rear section 7, 8 of the cross-country ski 3, in particular its sliding zones 102, 103 relatively stronger or weaker against the Ungrund be pressed ,

It is favorable if the at least one tension element 5, 6 undergoes a change of direction on at least one deflecting element 105, 106 such that the tension element 5, 6 lies between the lower belt below a neutral zone 107 of the gliding board body and that above the neutral zone 107 of the sliding board body overlying upper chord. This means that the at least one deflection element 105, 106 forms at least one force deflection point 108, 109 for the at least one variably pretensionable tension element 5, 6. The neutral layer or zone 107 of the sliding device 1 was indicated in principle in FIG. 20 with dash-dotted lines.

It is favorable if the at least one pulling element 5, 6 runs within the front and / or rear part section 7, 8 or within the sliding zones 102, 103 of the sliding board body in the lower flange of the sliding board body and close to the at least one deflecting element 105, 106 or from the at least one deflecting element 105, 106, the neutral zone 107 of the sliding board body traverses and in the pressure-loaded zone, ie merges into the upper flange of the sliding board body, as was schematically shown in Fig. 20. Thus, it may be that up to 70% of the length of the tension element 5, 6 run in the lower flange, while the rest in the upper flange or within the adjustment device 2 runs.

The presetting device 10 and additional setting device 11 tend to convert the tension element 5, 6 into an elongate or as straight as possible. As a result, especially the front and rear sections 7, 8 of the cross-country skiing 3 are pushed down. The deflecting elements 105, 106 for the at least one pulling element 5, 6 are preferably positioned outside, in particular in front of and behind the shoe contact zone 100, with reference to the longitudinal direction of the cross-country ski 3. It is advantageous to position the at least one deflecting element 105, 106 in the transition section between the climbing aid zone 104 and the sliding zone 102, 103. By forming the deflecting elements 105, 106 in these intermediate or transition zones, a bending stiffness bend or an inherent joint is virtually created in the bending characteristic of the sliding device 1, via which, in conjunction with the adjusting device 2, a particularly effective switching between reinforced or emphasized climbing aid characteristic and reinforced or highlighted sliding characteristic is achieved.

In Fig. 21, a further embodiment of an adjustment device 2 for individually influencing the flexural rigidity of a sliding board body is shown very schematically. The additional adjustment device 11 is formed, for example, by a quickly and easily operable actuating cam arrangement 23, on which at least one end of a one-part or multi-part tension element (not shown) is fastened. This additional adjustment device 11 is mounted directly on the presetting device 10 or is coupled with the presetting device 10 in a movement-coupled manner.

The presetting device 10 comprises at least one wedge arrangement 110 with wedge surfaces 111, 112 extending at an angle to each other. By means of an actuator 113, for example a screw arrangement, which acts on at least one wedge element of the wedge arrangement 110, the wedge elements are moved relative to one another, whereby at the same time a vertical Raising or lowering of Zusatzzstellvorrichtung 11 is effected. This adjustment device 2 thus also comprises independently operable adjustment means, in particular a presetting device 10 comprising at least one wedge element and an auxiliary adjustment device 11 which is coupled with movement but independent of the presetting device 10 and which, for example, is designed as an actuating cam arrangement 23 that can be converted comparatively quickly.

FIGS. 22 to 25 illustrate a further embodiment of an adjusting device 2 for the individual modification of the bending stiffness or the user behavior of a board-type gliding device, in particular a board-type winter sports device.

This setting device 2 comprises at least one presetting device, in particular a first presetting device 10 and a second presetting device 10 'for the finely graduated or stepless change and presetting of the desired tension in the lower belt of a belt board-like gliding device. This adjusting device 2 shown schematically is at least partially integrated into the structure of a sliding device.

In particular, a housing 14 of this adjustment device 2 is partially embedded in the Gleitgeräteaufbau, whereas the first handle 12 for the presetting 10 and a further handle 13 for the additional adjustment device 11 are preferably operated from the top of the sliding device. The housing 14 is made so tight that originally flowable adhesive or foam layers, as used in the production of the board-like sliding device, can not or only marginally penetrate into the interior of the housing 14.

Preferably, the interior of the housing 14 is at least partially provided with a lubricant, in particular filled with grease or at least the sliding surfaces within the housing provided with a maintenance-free lubricating layer, so that the adjustment device 2 is maintenance-free during the entire expected service life of a sliding device ,

Optionally, a schematically illustrated lid member 114 may be formed with which at least one of the handles 12, 12 ', 13 can be concealed or clad to obstruct icing or damage thereof. The cover element 114 is preferably designed in the manner of a pivotable flap or hood, in order thereby to achieve a loss-secured mounting of the cover element 114 on the board-like sliding device. In the illustrated position of the cover member 114, in which the controls or handles 12, 12 ', 13 are protected from external environmental influences, the cover member 114 is preferably secured by means of snap or snap connections, possibly also by means of a screw, against unwanted automatic pivoting.

The first presetting device 10 is provided according to the foregoing descriptions, the bending stiffness or the bending behavior of the gliding device to the respective desired value, for example to the corresponding weight of the user and / or the respective athletic performance and / or to each optimally adapt the planned sports discipline.

The second presetting device 10 'is intended to allow a kind of calibration or calibration of the board-like sliding device. In particular, by means of this second presetting device 10 'production-related tolerances can be better compensated. By virtue of this second presetting device 10 ', it is thus possible to at least reduce, in particular, manufacturing or component-related tolerances, or it is possible to achieve a relatively simple adaptation to a desired value provided by the producer. After a corresponding calibration of the board-type sliding device, in particular a cross-country ski, by means of this second presetting device 10 'is virtually created an initial state, from which then the respective user-side changes can be made by means of the first presetting device 10 and / or by means of the additional setting device 11. The second presetting device 10 'for balancing the actual and desired values relating to the bending behavior or the bending stiffness characteristic of the board-type sliding device is preferably exclusively factory-operable. In particular, provision may be made for the second presetting device 10 'after a factory calibration or after a dealer-side "Fine-Tuning". generally inaccessible to the general public. The handle 12 'of the second presetting device 10' can be designed for this purpose, for example, by a so-called worm screw with Allen, slotted, Phillips or multi-tooth head, so that a change to the second Voreinstellvorrichtung 10 'is held by the end user rather hinan. Preferably, a cover element 115, for example a closure plug or a closure cap is provided, with which the access to the handle 12 'after performing a factory calibration or after completion of a factory "zero balance". the Gleitgerätes 1 prevented or basically difficult 29/52 Austrian Patent Office AT506 545B1 2012-05-15 is. If appropriate, it is also possible to provide a seal which is attached to the second presetting device 10 'after the factory default setting or calibration. As a result, subsequent, generally undesirable changes to the second presetting device 10 ', which is provided primarily to compensate for production tolerances, can be easily understood. A possibly formed cover member 115 or a corresponding plug can also be designed such that the second presetting device 10 ', in particular its handle 12' after calibration without violence or without mechanical processing, for example by milling, drilling or grinding operations, not is more accessible. Unwanted manipulations on the second presetting device 10 'can thus be reconstructed in a simple manner.

For applying individually adjustable or variable tensile force effects of the adjusting device 2, the illustrated embodiment comprises at least one wedge assembly 110. In the illustrated embodiment, three independently adjustable wedge assemblies 110, 110 ', 110 " wherein the first wedge assembly 110 of the presetter 10, the second wedge assembly 110 'of the second presetter 10', and the third wedge assembly 110 " associated with the additional adjustment device 11. These wedge assemblies 110, 110 ', 110 " In this case, they can have different wedge angles in order to achieve different setting speeds or different change intensities. In particular, the additional adjustment device 11 may also have other types of adjustment mechanisms in order to achieve the desired by means of the additional adjustment device 11, pulse-like tensile force change. In particular, as an actuator for this wedge assembly 110 " a rocker arm assembly or a pivotally mounted angle lever, with which an abrupt relative position of the wedge assembly 110 ", in particular its wedge member 116 " can be made with respect to the housing 14.

The first presetting device 10 and the second presetting device 10 'each have wedge elements 116, 116' in the illustrated embodiment. The respective formed wedge elements 116-116 " within the housing 14, depending on the individual setting on the presetting device 10, 10 'or on the additional setting device 12, different widths or intensities between at least two slide elements 117, 118 in the housing 14 are forced into it. In particular, over the wedge surfaces of the wedge elements 116-116 " a variable distancing and approach between the slide elements 117, 118 causes. The at least two-fold, the wedge assembly 116 and the wedge assemblies 116-116 " oppositely arranged slide elements 117, 118 are preferably guided displaceably in a guide arrangement 119. Preferably, a guideway of the guide assembly 119 extends in the longitudinal direction of the sliding device or parallel to the pulling direction of at least one tension element 5, 6. Beispielsgemäß the guide assembly 119 is formed in the opposite side walls of the housing 14. By means of this guide arrangement 119, the slide elements 117, 118, which are designed at least twice, are guided in a linearly movable manner, their guide plane being oriented essentially parallel to the upper side or running surface of the sliding device. According to the illustrated embodiment with multiple wedge assemblies 110-110 " are between the individual wedge assemblies 110-110 ", in particular between the respective wedge members 116-116 " each additional slide elements 117 ', 118' is formed. The slide members 117, 117 'and 118, 118' are slidably supported along the guide assembly 119, as well as the wedge members 116-116 " held within the housing 14 quasi floating.

According to the embodiment shown, an individually variable tensile stress is exerted by means of the slider element 118 to the in a top view of the slider substantially U-shaped, double-stranded traction element 5. Similarly, the slider element 117 acts on the tension element 6, which preferably also grinding or. arcuate runs and thus preferably carried out double-stranded. The end sections of the preferably U-shaped traction elements 5, 6 facing away from the front section 7 and from the rear section 8 of a board-like sliding device overlap each other within the housing 2 of the adjustment device 2. By a user-side change in the overlap 28, in particular by increasing the overlap width 28 by means of the adjustment device 2, the tensile force or the bias in the tension elements 5, 6 is increased, as best seen by the arrow representations in Fig. 25. By reducing the overlap width 28 between the tension elements 5, 6, however, the bias in the tension elements 5, 6 is lowered and thereby reduces the rigidity of the corresponding sliding device. According to the embodiment according to FIGS. 22 to 25, the adjustable tensile force variation between the slide elements 117, 118 thus takes place by means of at least one wedge arrangement 110.

Also, the wedge members 116, 116 ', 116 " are floating within the housing 14. That is, each of the respective formed wedge members 116, 116 ', 116 " in the longitudinal direction of the tension elements 5, 6 is displaceable. In particular, the wedge elements 116, 116 ', 116 " not fixed in the longitudinal direction of the tension elements 5, 6 but slidably guided. As a result, compensating movements can take place between the tension elements 5, 6 and an at least approximately symmetrical tensile stress distribution between the rear and front tension elements 5, 6 can be achieved.

According to the illustrated embodiment, the tension elements 5, 6 pass through bores 120, 121 in the slide elements 117, 117 ', 118, 118'. The preferred rope-like tension elements 5, 6 are in each case firmly connected to the outer slide elements 118 and 117 or rigidly anchored to these slide elements 117, 118.

The manually operable actuator for the wedge assembly 110, 100 ', 110 " is by way of example by at least one adjusting spindle 42, 42 ', 42 " educated. The adjusting spindle 42, 42 ', 42 " adjusted by actuation of the handle 12, 12 ', 13 along its screw axis relative to the housing 14. This adjustment movement of the adjusting spindle 42, 42 ', 42 " is applied to the wedge member 116, 116 ', 116 " transferred to cause a more or less intense or pronounced distancing between the slide elements 117, 118. The adjusting spindle 42, 42 " is characterized by at least one guide groove 122 " held twisted. This guide groove 122, 122 " provides a floating support of the wedge elements 116, 116 " in the longitudinal direction of the sliding device or the tension elements 5, 6 safely. In addition, via this guide groove 122, 122 " a non-rotating support, in particular a blocking of any rotational movements of the adjusting spindle 42, 42 " achieved around the spindle axis. On the other hand, an axial mobility of the adjusting spindle 42, 42 " ensured when the respective handle 12, 13 actuated, in particular twisted. This handle 12,13 is connected to a rotatably mounted threaded sleeve 123 " in connection whose thread with the adjusting spindle 42, 42 " corresponds. The threaded sleeve 123, 123 " is secured for example by means of a circumferential collar or projection in the axial direction. By turning the threaded sleeve 123, 123 " or the handle 12, 13 coupled thereto, the adjusting spindle 42, 42 " displaced in the axial direction, in particular perpendicular to the top of the sliding device and thus the at least one wedge element 116, 116 " in its wedge or spreading effect against the sliding elements 117, 117 ', 118, 118' influenced. An advantage of this design of an axially fixed threaded sleeve 123, 123 " in conjunction with an axially adjustable adjusting spindle 42, 42 " is that a supernatant of the handle 12, 13 with respect to the top of the sliding device or against the cover member 114 of the housing 14, despite different settings does not change. This ensures a harmonious, visual appearance. It also avoids pile-like protruding elements or spindles or handling, which are on the one hand visually disturbing and can also represent an increased injury potential.

The actuator of the presetting 10 'is formed by a Stellspin del-42', for example, which is axially adjustable within a fixedly connected to the housing 14 threaded sleeve 123 'when the adjusting spindle 42' via the handle 12 ', in particular by means of a Auxiliary tool in the form of a screwdriver, is set in rotary motion. Instead of a threaded sleeve 123 ', a corresponding threaded portion for the adjusting spindle 42' may also be formed directly in the wall parts of the housing 14. In any case, the axially adjustable adjusting spindle 42 'determines the respective spreading or wedge effect of the wedge element 116'. A particular advantage of this adjusting device 2 is that it can be made structurally relatively solid, yet cost-effective. Another advantage is that this adjustment device 2 can be made relatively compact and yet the respective required Stellweiten or tensile force changes against the tension elements 5, 6 can be generated.

Instead of forming adjusting spindles 42-42 " in conjunction with threaded sleeves 123-123 " It is also possible to provide at least one toggle lever arrangement as actuator or adjusting means for the slide elements 117, 118. For example, the slider members 117, 118 may be hingedly connected to the distal ends of the toggle lever, whereas the middle hinge or knee joint cooperates with an actuator, such as an adjusting spindle or eccentric lever assembly, to vary the spreading angle between the lever members of the toggle lever and thus to influence the pulling action of the tension elements 5, 6. In a similar manner, scissors arrangement or pincer-like kinematics are also possible in order to achieve controllable distancing or approximation of the mutually overlapping ends of the tension elements 5, 6.

In Fig. 26, the operation of the adjusting device 2 comprising at least one presetting device 10, 10 'and further an additional adjustment device 11 is illustrated schematically.

According to this embodiment of the adjusting device 2, a presetting device 10 'is formed, with which production-related tolerances can be compensated or reduced. In particular, the bending stiffness or the so-called "flex behavior" can thus be determined. be calibrated or adjusted to a particular output value of the respective sliding device. An adjustment range of this presetting device 10 'can be, for example, approximately +/- 30 N depending on the respective production tolerances. A travel required for this purpose on the presetting device 10 'is usually about 3 mm. By means of this presetting device 10 'produced sliding devices can be calibrated or adjusted relatively accurately to a basic setting value of, for example, 50 kg. This calibration or adaptation preferably takes place at the factory or on the part of the dealer of corresponding sliding devices.

Starting from such a calibrated or uncalibrated output value, in any case, a presetting device 10 is formed, with which the respective bending behavior can be adapted to the respectively desired setting values. By way of example, the respective weight of the corresponding user is stated as the setting parameter. By way of example, by means of the presetting device 10, a setting can be made within a value range of 20 kg, in particular from 50 kg to 70 kg. Of course, other adjustment ranges or bandwidths are selectable. The travel required for the presetting device 10 is approximately 10 mm with respect to the tension elements 5, 6 (see FIG. 25).

In addition, the adjusting device 2 comprises the additional setting device 11, with which the values preset via the presetting device 10, in particular the bending stiffness values of the board-like gliding device abruptly and preferably without tools raised to a higher value and subsequently lowered in a simple manner again. This adjuster 11, which is also referred to as "overdrive means". can be designated, for example, allows a change in value by +/- 10 kg. That is, with a set value of 55 kg, it is possible to increment to approximately 65 kg by means of the adjuster 11 in a quick and easy manner. Likewise, a provision for the preset value of the preset device 10 of, for example, 55 kg is made possible in a simple and rapid manner. A required for the additional adjustment device 11 travel for the tension elements 5, 6 is only about 5 mm. By way of example, an adjustment travel to be applied by the presetting device 10 is only approximately 10 mm, in order thereby to achieve a setting range of 20 kg, based on the body weight of a user. These travel ranges can be achieved with the specified adjusters 2 perfectly 32/52 Austrian Patent Office AT506 545B1 2012-05-15.

From the diagram shown it can be seen in a simple manner that by operating the additional setting device 11, the values preset by means of the presetting device 10 can be quickly and effortlessly raised by a specific value and lowered again in a similarly rapid and abrupt manner. A board-type sliding device equipped with such an adjusting device 2 can thus better cope with a plurality of users and also a plurality of different environmental conditions, types of use, individual desired ideas and the like. In addition, a relatively high and relatively exactly reproducible quality level can be ensured with the board-type sliding devices equipped therewith.

For the sake of order, it should finally be pointed out that in order to better understand the construction of the sliding device 1 or the adjusting device 2, these or their components have been shown partly unevenly and / or enlarged and / or reduced in size. 31 deflecting loop 32 deflecting loop 33 deflecting element 34 deflecting element 35 guiding element 36 guiding element
