Abstract
Description
[0001] Son-in-law
[0002] The invention relates to a snow glider, in particular a ski, with a snow glider underside on which a
[0003] Sliding surface for gliding on snow, wherein in the snow glider a recess in the
[0004] Sliding surface open receiving space is arranged, and in the receiving space a carrier plate of the snow glider is movably mounted with a friction surface, wherein the friction surface has a higher coefficient of friction than the sliding surface, wherein the snow glider has an adjusting device with which the carrier plate can be moved between a retracted into the receiving space
[0005] end position and an operating position, wherein the friction surface in the operating position is arranged at least partially flush with the sliding surface or projects outwards beyond the sliding surface on the underside of the snow glider and is arranged offset from the sliding surface into the receiving space in the retracted end position.
[0006] Snow gliders and especially cross-country skis are offered in different versions according to the state of the art. In the case of cross-country skis, it can generally be said that the running surface of a cross-country ski is divided into three zones. At the front and rear are the
[0007] Gliding zones, i.e. the area that is always in contact with the snow and serves your gliding on the snow. In addition to the
[0008] The gliding zone of a cross-country ski is located in the middle area, usually under the binding, and is known as the climbing zone. Depending on the design, the climbing zone provides increased friction against the snow mechanically, i.e. by providing a friction surface, e.g. in the form of a skin or scale surface or by applying grip wax. Due to the concave shape of the gliding surface in combination with the tension of the cross-country ski, ideally only the gliding zones come into contact with the snow during the gliding phase. The gliding surface usually consists of a smooth polyethylene coating, which is ideally also coated with glide wax. On state-of-the-art cross-country skis, the climbing zone is only active when it is pressed into the snow by pressure on the ski. The cross-country skier can then actively push off the snow forward using the climbing zone in order to accelerate.In practice, however, undesirable braking effects often occur when the friction surface or climbing zone is pressed into the snow at the wrong time during the movement, especially in the gliding phase.
[0009] With other snow gliders, such as touring skis, telemark skis, and / or splitboards, the current technology involves gluing and / or stretching a skin to the gliding surface as a friction surface for uphill ascents. This skin is then removed before descending. The fact that the skin, intended to prevent backward sliding, also slows forward movement during uphill ascents is a common practice. Attaching the skin to the gliding surface and removing it from the gliding surface is a process that typically takes several minutes.
[0010] AT 14161 Ul introduces a movable, computer-controlled climbing zone. Specifically, a motor-driven plate moves along the path of a parallelogram, reducing the effort required during cross-country skiing. This movement also causes the plate to partially retract. Additionally, the movable plate is connected to the rest of the ski's gliding surface via a membrane.
[0011] The generic DE 3002 969 A1 discloses a cross-country ski in which the lowering of a support plate with a friction surface is coupled to the movement of the binding and thus of the foot or boot. This attempts to lift the friction surface off the snow surface during the gliding phases of the movement.
[0012] The object of the invention is to improve a device of the type mentioned at the outset in such a way that the sliding surface can develop its full effect even during hard use and a corresponding twisting of the snow glider, if this is desired.
[0013] For this purpose, the invention proposes that the snow glider has a locking device for releasably locking the carrier plate in the operating position.
[0014] The present invention provides for a snow glider, in particular a ski, to have a support plate with a friction surface that can be moved into at least two positions, namely the retracted end position and the operating position, in a matter of seconds, even while skiing. In the operating position, the support plate can be secured by means of the locking device. This fixation ensures that the support plate with the friction surface remains in the optimal position desired for pushing off on the snow, even when the snow glider is severely deformed or twisted during rigorous use and subjected to large forces.
[0015] The adjustment of the support plate in seconds between the operating position and the retracted end position using the adjustment device offers a significant advantage for the user, allowing immediate adjustment to current needs while standing or even while driving. Furthermore, the present invention also eliminates the negative effects of the braking effect in the gliding passages of the snow glider when the friction surface is offset into the receiving space in the retracted end position.
[0016] The friction surface has a higher coefficient of friction compared to snow than the sliding surface. The sliding surface serves to allow the snow glider to glide forward with as little friction as possible. In contrast, the friction surface, when pressed into the snow by a corresponding load on the snow glider, is designed to prevent the snow glider from sliding backward by creating friction on the snow. The friction surface pressed into the snow thus enables push-off and thus forward acceleration.
[0017] The term "regionally flush" means that the friction surface, in the operating position, forms a step-free, possibly even transition with the sliding surface, whereby this transition can be interrupted by a gap between the sliding surface and the friction surface. In the operating position, the friction surface can also protrude above the sliding surface on the underside of the snow glider. In this case, when the snow glider is subjected to a corresponding load, it is pressed particularly deeply into the snow. For the sake of completeness, it should be noted that in the course of describing this invention, the numbers used such as one, two, three and the like basically only describe the minimum number of a feature of the snow glider according to the invention. Individual features or components of the snow glider can of course also be present in larger numbers. In this sense, for example, the number "one" is to be understood as meaning "at least one", etc.
[0018] The locking device can have at least one pin-pin receptacle pair with a locking pin and a fixed pin receptacle, wherein the locking pin can be inserted into the pin receptacle for locking the carrier plate in the at least one operating position. It is possible for the locking pin or the associated pin receptacle to each have a cylindrical shape, a conical shape, or another elongated shape. In other words, it is possible for the locking pin to be an insertion element in any suitable shape, and the pin receptacle to be a receiving cavity in any suitable shape.The pin receptacle can enclose the locking pin, when inserted into the pin receptacle, circumferentially or at least partially, and the locking pin, which can be arranged on a free, projecting end of the push rods, can be guided into the pin receptacle or, in other words, extend into it through an opening, in particular at the end, of the pin receptacle, which can be located on a wall section of the snow glider. Furthermore, the locking device can have two of the pin-pin receptacle pairs. The support plate can then be lockable at opposite ends, in particular longitudinal ends, of the support plate by means of one of the pin-pin receptacle pairs, each on a wall section of the snow glider surrounding the receiving space.In this context, it is clarified that the longitudinal ends refer to the ends that point towards the tip of the snow glider and towards the end of the snow glider opposite the tip.
[0019] It can be provided that the locking pin(s), preferably each, is / are formed on a push rod, which can be part of the locking device. It is preferably provided that the locking pin(s) is / are formed on a freely projecting end of the push rod. The push rod can slide back and forth in the support plate. A push rod guide can be formed by the support plate. In the snow glider according to the invention, it can be provided that the locking pin(s), preferably each, is / are displaceably mounted in the support plate.
[0020] Furthermore, it is preferably provided that the pin receptacle or pin receptacles are preferably each formed in a wall section of the snow glider that surrounds the receiving space. In other words, this means that the receiving space can have a recess extending into the respective wall section on the corresponding sides, preferably each. The snow glider can be configured such that the support plate can be adjusted by the adjustment device in directions orthogonal to the friction surface. Preferably, it is adjustable exclusively in directions orthogonal to the friction surface.
[0021] It is conceivable that the friction surface can be arranged in a first plane in the retracted end position and in a further plane in the operating position, preferably in each operating position. The first plane and the further planes can be arranged parallel to one another, preferably one above the other.
[0022] In the device, it is preferably provided that the adjustment device is a purely mechanical adjustment device. It is also possible for the locking device to be a purely mechanical locking device. As an alternative to the purely mechanical design of the adjustment device and / or the locking device, it is also possible in principle for the adjustment device and / or the locking device to be motor-adjustable. This motor drive can have a user interface attached to the snow glider, but can also be wirelessly remote-controlled.
[0023] The invention can also provide for the adjusting device to have at least two mutually different locking positions. These two mutually different locking positions can be arranged one above the other, in which case there can then be an upper locking position and a lower locking position. It is preferably provided that the adjusting device is locked and / or releasably fixed in one of the locking positions in the operating position and in the retracted end position. It can be provided that the adjusting device is locked in an upper locking position in the retracted end position and is locked in a lower locking position in the operating position.
[0024] Furthermore, it should be mentioned that the locking device and adjusting device can be positively coupled to one another and / or can be controlled or actuated with the same actuating element of the snow glider. It can be provided that by actuating the actuating element, the adjusting device can be adjusted, preferably in the direction normal to the friction surface, and at the same time a displacement of at least one push rod is caused. As a result, the locking pin(s) arranged on the push rod(s) can be inserted into the respective pin receptacle. Analogously, it is preferably provided that upon corresponding actuation of the actuating element, both the adjusting device moves the carrier plate back into the retracted end position and the locking pin(s) is / are pulled out of the pin receptacle.
[0025] The actuating element can be constructed in one or more parts. In a preferred embodiment, the actuating element can consist of a guide element, fixed by screwing, a push-turn mechanism, and a column. It is also conceivable that the guide element can be attached to the snow glider in another way besides the classic screw connection. The guide element and / or the push-turn mechanism can be a fixed component of the adjustment device or can be removed from it at any time, preferably non-destructively—in other words, reusable.
[0026] In preferred embodiments, the snow glider has a forward-facing tip. Preferably, the snow glider has a ramp fixed to the gliding surface at the end of the receiving space facing away from the tip. Preferably, the ramp, with its end facing the receiving space, can be recessed into the snow glider relative to the surrounding portions of the gliding surface. The ramp can, particularly when the support plate is in the retracted end position, prevent snow from accumulating at the transition between the receiving space and the gliding surface when moving forward with the snow glider, thus avoiding undesirable braking effects when moving forward.
[0027] The friction surface can preferably be a fur surface and / or a scale surface and / or a grip wax surface. The different friction surface variants can either be permanently attached to the carrier plate or can be removed at any time, preferably non-destructively, i.e., reusable. The grip wax surface can be removed or replaced at any time.
[0028] The snow glider according to the invention can be a cross-country ski or a touring ski or a telemark ski or a splitboard.
[0029] Preferably, the snow glider has a binding for attaching a boot to the snow glider. The binding can be permanently connected to the snow glider or can be removed at any time without causing damage, i.e., in other words, reusable. It is therefore conceivable that the locking device and / or the adjusting device can be used flexibly with all types of bindings and / or all types of snow gliders. Preferably, the adjusting device and / or the locking device is / are designed separately from the binding. Thus, the adjusting device can be mounted separately or together with the locking device, independently of the binding, but can also be replaced. Thus, it is also possible to use the adjusting device and / or the locking device together with different types of bindings.

[0050] The figures disclose an embodiment of a snow glider 1 according to the invention in the form of a cross-country ski. As already explained at the beginning, other snow gliders 1 such as touring skis, telemark skis or splitboards can also be designed according to the invention if the technical teaching illustrated here with reference to a cross-country ski is implemented accordingly for these other types of snow gliders 1. Fig. 1 shows a top view, Fig. 2 shows a side view shown in section in the region of the receiving space 4 and Fig. 3 shows a bottom view of the entire snow glider 1. The snow glider 1 has a tip 23 pointing forward during forward travel. On the underside 2 of the snow glider 1 is the gliding surface 3, with which the snow glider 1 can glide on the snow. On the upper side 28 of the snow glider, opposite the underside 2 of the snow glider, a binding 24 is mounted on the snow glider 1.This can be designed in various ways known in the state of the art and serves to attach the shoe 2.5 to the snow glider 1.
[0051] In the snow glider 1 there is a receiving space 4 open towards a recess in the sliding surface 3. In this space a carrier plate 5 of the snow glider 1 is movably mounted with a friction surface 6, wherein the friction surface 6 has a higher coefficient of friction with snow than the sliding surface 3. The friction surface 6 can be, for example, a fur surface and / or a
[0052] scale surface and / or a grip wax surface.
[0053] In the bottom view according to Fig. 3 it can be seen that in preferred embodiments, as also realized here, the receiving space 4 is surrounded on all sides by the sliding surface 3. In other words, the receiving space 4 advantageously does not extend anywhere to an edge of the snow glider underside 2.
[0054] The snow glider 1 has an adjustment device 7 with which the support plate 5, and thus also the friction surface, can be adjusted between an end position retracted into the receiving space 4 and an operating position. Figures 4, 5, and 6 show an enlarged view of the central area of the snow glider 1, in which the receiving space 4 and the support plate 5 are located. Figure 1 shows a quasi-transparent plan view of this area, while Figure 2 shows a partially open plan view of the central area.
[0055] 5 and 6 each show longitudinal sections through this area. In Fig. 5, the carrier plate 5 and the friction surface 6 are in the end position retracted into the receiving space 4, and in Fig. 6 in the operating position, in which the friction surface 6 is arranged at least partially flush with the sliding surface 3 surrounding the receiving space 4. While the friction surface
[0056] 6 in the retracted end position according to Fig. 5 is arranged offset into the receiving space 4 and is thus lifted off the snow on which the snow glider 1 slides with the sliding surface 3, it is in the operating position according to Fig. 6 with corresponding load of the snow glider
[0057] 1 into the snow. Due to its increased coefficient of friction compared to snow, the friction surface 6 then prevents the snow glider 1 from sliding backward in the operating position and thus allows pushing off and thus accelerating forward, while in the retracted end position it does not hinder the snow glider 1 from sliding forward with its sliding surface 3 on the snow.
[0058] At this point, however, it should also be noted that the friction surface 6 in the operating position does not necessarily have to be arranged flush with the sliding surface 3. In correspondingly modified embodiments, the friction surface 6 in the operating position can also protrude outwards beyond the sliding surface 3, whereby it is then pressed even deeper into the snow when the snow glider 1 is subjected to a corresponding load, thereby generating even greater friction with the snow. In the following, the purely mechanically designed adjustment device used here in this embodiment shown in the figures for adjusting the support plate 5 together with the friction surface 6 between the retracted end position and the operating position
[0059] 7 is explained with reference to Figs. 9, 10, 14 and 15. Here, in this embodiment, this adjustment device 7, as in other preferred embodiments, is designed as a push-turn mechanism 9. It can be operated manually and without tools using the actuating element 8, which is designed here as a push-turn lever, so that adjustment of the support plate 5 including the friction surface 6 between the retracted end position and the operating position is possible in a matter of seconds, both while standing and while driving the snow glider 1.
[0060] Before we go into more detail about the adjusting device 7 implemented here, it should be noted at this point that in snow gliders 1 according to the invention, the adjusting device 7 can of course also be designed completely differently. For example, a motorized design can also be provided in which the adjustment of the support plate 5 including the friction surface 6 is carried out by motor, e.g., by means of a push button that can be operated by hand or with a ski pole, or even by remote control. The adjusting device 7 can also be a screw drive, scissor drive, or a pneumatic, hydraulic, electric, or other linear drive that can be operated manually, with or without tools, or is motor-driven.
[0061] In the variant implemented in this exemplary embodiment, the support plate 5 is adjusted by the adjustment device 7 exclusively in push-pull directions 27 orthogonal to the friction surface 6, which can of course also be implemented in other embodiments of the invention. In this and other preferred embodiments, the friction surface 6 is arranged in a first plane 21 in the retracted end position and in a further plane 22 in the operating position, with these two planes 21 and 22 running parallel to one another. The further plane 22 corresponds to the snow surface along which the snow glider 1 glides with its sliding surface 2.
[0062] 9 and 14 show cross sections through the adjusting device 7 implemented here in this exemplary embodiment, wherein the carrier plate 5 including the friction surface 6 is in the retracted end position in Fig. 9 and in the operating position in Fig. 14. Figs. 10 and 15 show longitudinal sections through the adjusting device 7 implemented here in this exemplary embodiment, wherein the carrier plate 5 including the friction surface 6 is in the retracted end position in Fig. 10 and in the operating position in Fig. 15. In Figs. 9 and 10, the friction surface 6 lies in the plane 21 in which it is lifted off the snow. In Figs. 14 and 15, the friction surface 6 lies in the plane 22 and thus on the snow surface when the snow glider 1 lies with its sliding surface 3 on the snow.
[0063] The adjustment device 7 implemented here comprises the actuating element 8 and is designed as a push-turn mechanism 9. The push-turn lever
[0064] Actuating element 8 can be operated by hand and without tools. It is guided in a guide element 10, which here is essentially sleeve-shaped. The guide element 10 is fixed to the upper side 28 of the snow glider 1. The guide element 10 has two locking positions 18 and 19 of the adjusting device 7, arranged one above the other and thus different from one another. The actuating element 8 has a locking pin 29 with which it can lock into the locking positions 18 and 19. In the retracted end position according to Figs. 9 and 10, the locking pin 29 locks in the upper locking position 18 and in the operating position according to Figs. 14 and 15, it locks in the lower locking position 19. An adjustment between these two end positions of the actuating element 8 is carried out by corresponding pivoting in the pivoting directions 26 and corresponding displacement in the push-pull directions 27, in this example by hand.Of course, a corresponding motorized adjustment of the actuating element 8 and thus of the adjusting device 7 would also be conceivable.
[0065] By means of the corresponding pivoting movements of the actuating element 8 in the pivoting directions 26, the locking pin .28 is moved into and out of the locking positions 18 and 19. If the
[0066] If the actuating element 8 is pressed downwards in the corresponding push-pull direction 27 after the locking pin 29 has been moved out of the upper locking position 18, the lower end 30 of the actuating element 8 pushes the carrier plate 5 together with the friction surface 6 from the retracted end position according to Fig. 9 and 10 downwards into the operating position according to Fig. 14 and 15. There the locking pin 29 is then locked into the lower locking position 19 by correspondingly pivoting the actuating element 8 in the corresponding pivoting direction 26.
[0067] If the carrier plate 5 and friction surface 6 are to be adjusted in the opposite direction, the locking pin 29 is first moved out of the lower locking position 19 by pivoting the actuating element 8 in the corresponding pivoting direction 26. The actuating element 8 is then pulled upwards in the corresponding push-pull direction 27. The actuating element 8 thereby pulls the carrier plate 5 together with the friction surface 6 from the operating position according to Figs. 14 and 15 upwards into the retracted end position according to Figs. 9 and 10. The locking pin 29 is then moved into the upper locking position 18 by pivoting the actuating element 8 in the corresponding pivoting direction 26.
[0068] In order to be able to pull the support plate 5 together with the friction surface 6 lix upwards in the corresponding push-pull direction 27, the actuating element 8 is connected to the column 16 via the collar-shaped positive connection 31. The positive connection 31 allows pivoting of the actuating element 8 relative to the column 16 in the pivot directions 26. During movements in the push-pull directions 27, however, the column 16 is positively coupled to the actuating element 8 via the positive connection 31. If the actuating element 8 is moved in one of the push-pull directions 27, it forcibly moves the column 16. At its lower end, the column 16 is articulated to a sequence of push rods 15 via tabs 31, with the successive push rods 15 in turn being articulated to one another by means of tabs 32.The push rods 15 and the tabs 32 are slidably mounted in guide channels 33 in the support plate 5, this displaceability being limited by the end stops 34 and 35 of the support plate 5 shown in Figs. 7, 8, 12 and 13, which are explained in more detail below. If the push rods 15, as shown in Fig. 7 and 8, rest on the end stops 34 of the carrier plate 5, the carrier plate 5 together with the friction surface 6 hangs on the push rods 15. If the actuating element 8 is now pulled upwards in the corresponding push-pull direction 27, it takes the column 26 and thus the push rods 15 hanging on the column 26 via the tabs 32 and thus ultimately also the carrier plate 5 together with the friction surface 6 upwards, so that the carrier plate 5 and the friction surface 6 are adjusted from the operating position into the retracted end position.
[0069] If the push rods 15, as shown in Figs. 12 and 13, rest against the end stops 35 of the support plate 5, the support plate 5 including the friction surface 6 is located in the further plane 22 and thus in the operating position. If the actuating element 8 is pressed downward in the corresponding push-pull direction 27, it presses the column 26 and thus the push rods 15 arranged on the column 26 via the tabs 32 and thus, via the end stops 35, ultimately also the support plate 5 including the friction surface 6 downward, so that the support plate 5 and the friction surface 6 are also thereby moved from the retracted end position into the operating position.
[0070] According to the invention, the snow glider 1 of the exemplary embodiment shown here not only has the adjusting device 7, but also a locking device 11. With the locking device 11, the support plate 5 can be releasably locked in the operating position. In this exemplary embodiment, the locking device 11 is also designed purely mechanically. Alternatively, motor-driven locking devices 11 could also be used in other variants of the invention. Even if this is not absolutely necessary, in this exemplary embodiment it is also provided that the locking device 11 and the adjusting device 7 are positively coupled to one another. They are both actuated with the same actuating element 8.This forced coupling has the advantage that the user of the snow glider only has to actuate one part, namely the actuating element 8, in order to adjust the carrier plate 5 including the friction surface 6 between the retracted end position and the operating position and simultaneously perform a corresponding locking and unlocking. Here, too, it should be noted that other design variants are possible. This forced coupling does not necessarily have to be released purely mechanically, as is the case here. A control-based and / or electronic forced coupling is also conceivable, particularly if the adjusting device 7 and the locking device 11 are motor-driven. It is also conceivable not to forcibly couple the adjusting device 7 and the locking device 11 at all, but to design them so that they can be controlled and / or operated individually or separately. Both purely mechanical and motor-driven solutions are conceivable for this purpose.
[0071] In the variant specifically implemented in this exemplary embodiment, the locking device 11 of the snow glider 1 has two pin-pin receptacle pairs 12, each with a locking pin 13 and a pin receptacle 14, wherein the respective locking pins 13 can be inserted into the respective pin receptacle 14 to lock the carrier plate 5 in the operating position. It should be noted that the use of only one pin-pin receptacle pair 12 or more than two pin-pin receptacle pairs 12 is also conceivable for implementing the invention. In this exemplary embodiment, the carrier plate 5 can be locked at its longitudinal ends pointing toward and away from the syringe 23 by means of a respective pin-pin receptacle pair 12 to a wall section 17 surrounding the receiving space 4. The areas of the snow glider 1 in which the Zapfen™ pin receptacle pairs 12 are located are shown in Fig.7, 8, 12 and 13 are shown enlarged in the form of longitudinal sections through the snow glider 1. 7 and 12, and the end regions of the receiving space 4 and the adjoining wall sections 17 of the snow glider 1 pointing away from the tip 23, in Figs. 8 and 13. Figs. 7 and 8 show the retracted end position of the carrier plate 5 including the friction surface 6 and an unlocked state of the locking device 11. Figs. 12 and 13 show the operating position of the carrier plate 5 including the friction surface 6 and the locked state of the locking device 11. In the locked state, the carrier plate 5 and the friction surface 6 are connected particularly stably to the surrounding areas of the snow glider 1, so that they remain in their optimal position even when subjected to great forces and corresponding twisting or bending of the snow glider 1.
[0072] In this exemplary embodiment, the locking pins 13 are each formed on one of the aforementioned push rods 15, specifically at their freely projecting ends. The pin receptacles 14 are each formed in the wall sections 17 of the snow glider 1 surrounding the receiving space 4. This is not mandatory. Implementation in the other direction is also possible.
[0073] The locking pins 13 are slidably mounted in the support plate 5, specifically in its guide channels 33. This is inevitable in this exemplary embodiment, since the locking pins 13 are formed on the freely projecting ends of the push rods 1.5, which, as already described above, are slidably mounted together with the tabs 32 in the guide channels 33 of the support plate 5.
[0074] In this embodiment, the insertion of the locking pins 13 into the pin receptacles 14 (see Figs. 12 and 13), and thus the locking, occurs automatically when the actuating element 8, as already described above, is moved downward in the push-pull direction 27 and the column 16 shifts the respective sequence of tabs 32 and push rods 15 accordingly in the guide channels. The end stops 35 limit this shifting movement in this embodiment, but this is not necessarily the case.
[0075] To unlock, the actuating element 8 is moved upwards in the corresponding push-pull direction 27, as described above. Via the respective connection of the actuating element 8, column 16, tabs 32 and push rods
[0076] 15 the locking pins 13 are then pulled out of the pin receptacles 14.
[0077] In Figs. 8 and 13, it can be seen that the sliding surface 3, at the end of the receiving space 4 facing away from the tip 23, has a ramp 20 fixed to the snow glider 1, the end of which facing the receiving space 4 is offset into the snow glider 1 relative to surrounding portions of the sliding surface 3. In the retracted end position according to Fig. 8, the friction surface 6 adjoins flush with this end of the ramp 20 facing the receiving space 4. This has the advantage that, even in this retracted end position, when the snow glider 1 travels straight forward, no snow can accumulate at a freely projecting end of the sliding surface 3, which would have a correspondingly negative braking effect. In the operating position according to Fig. 1.3, this ramp 20 has neither positive nor negative effects.
[0078] Figs. 11 and 16 show cross-sections through the snow glider 1 in the area between the areas shown in Figs. 9, 10, 14, and 15, on the one hand, and those shown in Figs. 7, 8, 12, and 13, on the other hand. Fig. 11 shows the retracted end position of the carrier plate 5 including the friction surface 6, and Fig. 16 shows the operating position.
[0079] Finally, it should be noted that in the exemplary embodiment explained here, the adjustment device 7 and the locking device 11 are designed separately from the binding 24. This is not necessarily the case, but it has the advantage that, with the snow glider 1 according to the invention, a wide variety of commercially available bindings 24 can be used to attach the boot 25 to the snow glider 1.
