Description

[0001] The invention relates to a clamping device for adjustable variation of the boundary or receiving volume of a ski boot, as well as to a ski boot with such a clamping device, as specified in the claims.

[0002] WO2021138592A1 discloses, in the embodiments according to Figures 31 to 33, a ski boot, in particular a cross-country ski boot, with a tensioning device for tightening the sports boot. The tensioning device comprises an elongated plate that can be positioned on the ski boot. The elongated plate has a proximal end and a distal end. A tensioning mechanism is coupled to the proximal end of the elongated plate. The tensioning device further comprises a cable-shaped tensioning element that is operatively coupled to the tensioning mechanism, such that actuation of the tensioning mechanism adjusts a tension of the tensioning element. The tensioning device further comprises at least one guide element that is coupled to the elongated plate between the proximal end and the distal end.The cable-shaped tensioning element can be operated with the at least one guide element such that the tensioning element is guided around the article and along a portion of the elongated plate. The elongated plate can consist of plastic elements made of a relatively low-friction material so as to create a lower-friction surface on which the cable-shaped tensioning element slides. This allows the tensioning element to facilitate the closing of the longitudinal slot or the opening of the ski boot. According to one embodiment, the elongated plate is intended to slide freely in the longitudinal slot or opening of the ski boot. In other embodiments, the elongated plate can be firmly attached to the ski boot, namely at a distal end of the longitudinal slot or opening. Furthermore, the elongated plate can be attached to the ski boot by sewing, gluing, welding, mechanical fastening, etc.The respective designs described attempt to comfortably adjust the fit of ski boots, but these designs are technically complex, which has an adverse effect on the manufacturing costs and the robustness of such ski boots.

[0003] DE102013112017B4 describes a lacing device for a ski boot, wherein the ski boot has a sole and a hard shell, wherein the hard shell has, at least in the toe and instep area of ​​the boot, an upper and lower shell section which overlap along the center plane of the ski boot. The lacing device comprises at least one rope- or band-shaped pulling means, a first and second fastening means, and at least one first to third deflecting means, wherein at least one of the deflecting means and / or the fastening means is designed in the form of a tensioning means for introducing at least a first tensioning force into the lacing device. The first fastening means can be designed as a rotating element, i.e. the tension is generated by rotating the first fastening means. This embodiment also requires a particularly robust tensioning means, which can result in relatively high manufacturing costs for the ski boot.

[0004] EP0056953B1 discloses a closure device, particularly for ski boots. The closure device comprises a box-shaped body associated with one of the ski boot flaps to be tightened and provided with a knob for actuating a reel to which at least one tensioning cable is attached. The tensioning cable is further connected to the other of the ski boot flaps to be tightened. Furthermore, a ratchet mechanism is provided, which is driven by the knob and is designed to lock the reel in any selected position when the knob is turned in one direction and to release the reel when the knob is turned in the opposite direction. Such a closure or winding device can enable a comfortable closure of a ski boot, but must be able to withstand high forces, especially in ski boots for alpine downhill skiing.

[0005] The object of the present invention was to overcome the disadvantages of the prior art and to provide a ski boot or tightening device for a ski boot by means of which a user is able to comfortably close or tighten the ski boot and yet achieve a high level of robustness of the ski boot at the lowest possible manufacturing costs.

[0006] This object is achieved by a tensioning device and a ski boot according to the claims.

[0007] The tensioning device according to the invention is designed for the adjustable modification of the confining or receiving volume of a ski boot. It comprises a support plate which is intended to be fastened to the ski boot. Furthermore, it comprises a winding device with at least one spool for winding and unwinding at least one tensioning cable as required, which winding device is fastened or can be fastened to the support plate. The support plate has at least one fastening means which is designed to be preferably rigidly or firmly connected to at least one corresponding anchoring means on the ski boot. The at least one corresponding anchoring means on the ski boot can be used alternatively for fastening or mounting a lever-operated tensioning buckle on the ski boot or for fastening orMounting of an associated component of a lever-operated tensioning buckle, for example a locking or toothed strip.

[0008] The tensioning device according to the invention enables the efficient provision of ski boots with technologically different tensioning devices for adjustable modification of the confining or receiving volume of these ski boots. In particular, a ski boot or its outer plastic shell can be easily equipped either with the claimed tensioning device comprising a cable winding device, or alternatively, with at least one lever-operated tensioning buckle in order to be able to modify the receiving volume of the ski boot or the fit of the ski boot relative to the user's foot.Because the support plate is dimensioned and its fastening means are designed in such a way that these fastening means can interact with the anchoring means on the boot side, the support plate can be quickly mounted on a corresponding plastic shell of a ski boot. This plastic shell can preferably be formed by the cuff and / or the forefoot shell of a ski boot. In addition, the support plate for the rope winding device, which is mounted on the upper side of a ski boot, enables a robust and relatively stable attachment of the winding device, preferably to a cuff of the ski boot. The term cuff is understood to mean the component of a ski boot which is intended to enclose the lower leg section of a user and is articulated to the forefoot shell.The support plate with at least one fastening means represents an efficient means for rigidly or permanently securing the winding device to a ski boot, thus achieving production-related advantages. This can potentially result in significant savings in mold and tool costs, which are required for the injection molding of ski boots with an outer shell made of injection-molded plastic. However, the tensioning device according to the invention can also optimize inventory management and production flexibility. In addition, the corresponding anchoring means on the ski boot, which is provided in an alternative application for fastening or mounting a lever-operated tensioning buckle on the ski boot, already generally exhibits a high degree of robustness and load-bearing capacity and can thus ensure high tear resistance for the support plate.

[0009] Especially when the demanding tensioning device is assigned to the cuff of a ski boot for alpine downhill skiing, an alpine downhill ski boot can be created that is comfortable to use, robust and at the same time as cost-effective to produce as possible.

[0010] According to one embodiment, it can be provided that the at least one fastening means on the support plate preferably comprises at least two first openings in the support plate, that the at least one corresponding anchoring means on the ski boot preferably comprises at least two second openings, and that the first and second openings correspond positionally, in particular fit together spatially and structurally, so that the support plate can be fastened to the ski boot by means of at least one connecting means, for example by means of screws or rivets. The at least one connecting means is preferably provided to penetrate corresponding pairs of first and second openings and to mechanically connect or couple them firmly.The formation of openings and preferably screw- or rivet-like connecting means enables a quick and at the same time robust assembly either from the support plate with the winding device, or alternatively from the at least one lever-operated tensioning buckle.

[0011] Furthermore, it can be provided that the at least one fastening means on the support plate comprises a first and a second fastening means spaced apart from one another, and that these two fastening means and the winding device define a triangular arrangement on the support plate composed of three vertices. The winding device is positioned at the third vertex, and this third vertex lies between the first and second vertices with the fastening means when a normal to a straight line connecting the first and second vertices intersects the third vertex. Such a triangular arrangement, the vertices of which are defined by two fastening means for the support plate and by the winding device on the support plate, enables a statically optimized attachment of the support plate to the outer surface of a ski boot.

[0012] Furthermore, it can be provided that a base plate of the winding device is connected to the support plate in a tear-proof manner, in particular by means of at least one screw or rivet, preferably by means of at least three screws or rivets. In this way, the winding device can be pre-assembled on the support plate in a tear-proof manner before the support plate is connected to the ski boot, in particular to its plastic shell. In addition, this makes it possible to mount the winding device on the support plate without screw or rivet heads being visible when the ski boot is in use. This is the case, for example, when screws or rivet heads are closest to the underside of the support plate, which underside is closest to the surface of the ski boot.

[0013] Another advantageous embodiment is one in which the tensioning device is provided for fastening or mounting to a cuff of a ski boot, which cuff is designed to enclose the lower leg section of a ski boot user. This creates a ski boot cuff that can be conveniently and easily tightened, loosened, or opened using a rope winding device. The base or shell body of the ski boot cuff can alternatively or as standard be provided for the attachment of at least one lever-operated tensioning buckle.

[0014] According to a further development, it is possible for at least one of the two fastening means on the support plate to also be provided as an anchor point for at least one end of the at least one tensioning cable distal to the winding device, or for the support plate to have a first and a second fastening means, which are also each provided as anchor points for the distal ends of a first and a second tensioning cable of the winding device. As a result, the at least one fastening means is used multiple times, thereby keeping manufacturing and / or assembly costs as low as possible. Furthermore, this allows for a stable anchoring of the at least one end of the tensioning cable distal to the winding device.

[0015] Alternatively, it may be expedient if at least one of the two fastening means on the support plate is also provided as a deflection means for a tensioning cable of the winding device designed as a closed loop, or if the support plate has a first and a second fastening means, which are each also provided as a deflection means for a tensioning cable of the winding device designed as a closed loop. This prevents one end of the tensioning cable from being located outside the winding device. Outside the winding device, the tensioning cable can thus be designed as a relatively large or two-strand loop, which loop encloses at least one of the two deflection means, preferably both deflection means, or is guided or held in position by the at least one deflection means. The robustness and tensile strength of the winding device and the tensioning cable can thereby be promoted.In addition, this eliminates the need for complex anchor loops or anchoring eyes at the end of the tensioning cable.

[0016] Furthermore, it can be provided that a receiving channel is formed in an upper side of the support plate facing away from or away from a ski boot, which channel extends at least partially between the first and second fastening means in its longitudinal direction and is intended to receive a section of the tensioning cable. This receiving channel can be provided for the contact-free crossing of sections of the tensioning cable. This can prevent the tensioning cable from fraying or chafing at such a crossing point. A self-crossing course of the tensioning cable can achieve advantageous tensile stresses and advantageous directions of these tensile stresses.

[0017] Furthermore, it can be provided that the receiving channel is designed as a slot in the upper side of the support plate, which slot can be at least partially covered by a cover element in the radial direction to the longitudinal axis of the slot. This allows for easy accommodation of the corresponding section of the tensioning cable in the receiving channel, even if the tensioning cable is designed as a closed loop outside the winding device. Furthermore, after inserting the tensioning cable into this receiving or guide slot, an undesired falling out of the corresponding cable section from the slot can be prevented. In particular, this can facilitate the handling of the tensioning device.

[0018] According to an advantageous embodiment, the support plate can be spatially contoured in such a way that it follows, or largely follows, the spatial surface contour of the ski boot at the attachment point for the support plate. This ensures a slim design. In particular, it can minimize interfering contours on a ski boot. According to a practical implementation measure, the support plate can be made of injection-molded hard plastic.

[0019] According to an advantageous development, it can be provided that the at least one fastening means on the support plate comprises at least one positively acting first coupling element, preferably at least one latching hook, on the underside of the support plate and / or in a peripheral section of the support plate, which can be brought into positive engagement with at least one positively acting second coupling element on the ski boot, preferably with at least one corresponding recess or undercut on the ski boot, so that when a first and a corresponding second coupling element are positively coupled, lifting of the support plate from the ski boot is prevented or held back. This allows for rapid and stable installation of the clamping device on a ski boot.In addition, at least individual fastening elements for the clamping device can be implemented invisibly, so that a positive overall visual impression can be achieved with little structural effort.

[0020] Furthermore, it may be advantageous if at least one load distribution element, in particular a shim or pressure distribution plate, is assigned to the at least one fastening means, which at least one load distribution element is provided to increase the dimensional stability or to stiffen the support plate in its at least one fastening section relative to a ski boot. The support plate can thus be designed with relatively thin walls and thus, advantageously, as lightweight as possible. Point loads in the area of ​​the at least one fastening means are prevented, thus ensuring the intended function of the tensioning device in the long term.

[0021] Furthermore, it can be provided that the support plate has a recess on its upper side closest to the winding device, in which recess the winding device is at least partially received, or by which recess the winding device is at least partially delimited. This advantageously ensures that the winding device sits securely on the support plate. Furthermore, potentially occurring impact forces in the radial direction to the winding device can be absorbed by the support plate, thus reducing the risk of damage to the winding device. Furthermore, undesired snagging or impact points can be prevented by forming inclined or deflecting surfaces at least in partial sections of the peripheral area of ​​the recess. This can also promote the general robustness and practicality of the tensioning device.

[0022] The object of the invention is further achieved by a ski boot. A ski boot according to the invention comprises a forefoot shell for receiving a user's foot, a cuff for receiving the user's lower leg section, the cuff being hingedly connected to the forefoot shell, and a tensioning device for adjustable variation of the enclosure or receiving volume of the ski boot. The tensioning device comprises a support plate attached to the ski boot, a winding device with at least one spool for winding and unwinding at least one tensioning cable as required, which winding device is attached or can be attached to the support plate.

[0023] The support plate has at least one fastening means, via which at least one fastening means interacts with at least one corresponding anchoring means on the ski boot, in particular on its outer shell, preferably made of plastic, and is thus rigidly or firmly connected to the ski boot. The at least one corresponding anchoring means on the ski boot is provided in an alternative use for fastening or mounting a lever-operated tensioning buckle on the ski boot or for fastening or mounting an associated component of the lever-operated tensioning buckle, for example in the form of a locking or toothed strip.

[0024] This makes it easy to provide structurally different designs of ski boots, the capacity or fit of which on the user's foot can be influenced, at least in partial sections of the ski boot, either by attaching a cable winding device or, alternatively, by attaching at least one lever-operated tensioning buckle. The optional attachment of a cable winding device or at least one lever-operated tensioning buckle to a ski boot preferably takes place during the manufacturer's production or assembly of the ski boot and can be done quickly and with high quality. The support plate for the cable winding device, which can be rigidly mounted on the ski boot or its outer shell, is an essential element for achieving high stability and practicality.A particular advantage is that the at least one anchoring means arranged on the ski boot, in particular on its outer shell, can be used both for attaching the winding device or its support plate, as well as for attaching at least one preferably standard, lever-operated tensioning buckle. The claimed design enables the achievement of production-related advantages, particularly with regard to cost minimization, production flexibility, and inventory management. Furthermore, it allows a broader range of user requirements regarding ski boot performance and comfort to be met in a simple manner.

[0025] A ski boot according to the invention may have further developments as described above. The advantageous effects and results that can be achieved thereby can be found in the preceding and subsequent sections of the description.

[0026] For a better understanding of the invention, it is explained in more detail with reference to the following figures.

[0027] They show in a simplified, exemplary representation: Fig. 1 shows a ski boot known from the prior art with a plurality of lever-operated tensioning buckles on the outer shell body of the ski boot for individually changing the volume of the ski boot; Fig. 2 shows the ski boot according to Fig. 1 , wherein the pair of lever-operated tensioning buckles on the ski boot cuff has been replaced by a tensioning device comprising a manually operable winding device for a tensioning cable; Fig. 3 shows a further embodiment of a ski boot cuff with a tensioning device attached thereto in the manner of a tensioning cable winding device, viewed obliquely from below; Fig. 4 shows the ski boot cuff according to Fig. 3in side view; Fig. 5 a tensioning device in a non-assembled state with a winding device for a two-strand tensioning cable; Fig. 6 a support plate of the tensioning device without winding device; Fig. 7 the ski boot cuff according to Fig. 4 with the clamping device removed; Fig. 8 shows another embodiment of a support plate of a clamping device with a winding device.

[0028] By way of introduction, it should be noted that in the variously described embodiments, identical parts are provided with identical reference symbols or component designations, whereby the disclosures contained in the entire description can be applied mutatis mutandis to identical parts with identical reference symbols or component designations. Furthermore, the positional information chosen in the description, such as top, bottom, side, etc., refers to the directly described and illustrated figure, and in the event of a change in position, these positional information must be applied mutatis mutandis to the new position.

[0029] In Fig. 11 shows a side view of an embodiment of a known ski boot 2 for practicing alpine skiing. Such a ski boot 2 comprises a forefoot shell 21 for receiving the user's foot and a cuff 13, also called a ski boot cuff, which is articulated to the forefoot shell 21 and is intended to receive the user's lower leg section. The cuff 13 and the forefoot shell 21 define outer shell parts or an outer shell body of the ski boot 2, which shell parts or shell body are preferably formed from injection-molded plastic, in particular hard plastic. The forefoot shell 21 can be designed with an overlapping construction, i.e., with wing sections that overlap in the instep area. The cuff 13 is also designed with an overlapping construction, with cuff flaps in the front area of ​​the cuff 13 overlapping when the cuff 13 is closed or tensioned.An inner shoe 30 can be accommodated in the outer shell body, which is intended for softly elastic wrapping or embedding of the lower leg section and the foot of the user.

[0030] At least one lever-operated tensioning buckle 8 is formed on the forefoot shell 21 and on the cuff 13 of this known ski boot 2, respectively, in order to be able to change the receiving volume or the fit of the ski boot 2 according to the needs of a user. Such a tensioning buckle 8 can comprise an actuating lever 31, a coupling element 32, a locking or toothed strip 33, and a base plate 34, which base plate 34 is provided at least for the pivotable mounting of the actuating lever 31.

[0031] The tension buckles 8, in particular their base plates 34, are connected to the ski boot 2, in particular to the cuff 13 or to the forefoot shell 21, via anchoring means 7. The anchoring means 7 on the ski boot 2 can comprise openings 10 formed in the cuff 13 or in the forefoot shell 21. The anchoring means 7 further comprise screws or rivets, which penetrate these openings 10 and optionally also the base plates 34 and ensure a tear-resistant attachment of the lever-operated tension buckles 8 to the surface of the ski boot 2.

[0032] In the previously known ski boot 2 shown as an example, two lever-operated tensioning buckles 8 are positioned on the cuff 13 and on the forefoot shell 21.

[0033] In Fig. 21 shows an embodiment of a ski boot 2 with a tensioning device 1 comprising a winding device 4 for at least one tensioning cable 5. The tensioning device 1 is fastened to the cuff 13 of the ski boot 2. Alternatively or in combination therewith, such a tensioning device 1 can be provided on the forefoot shell 21. By actuating, in particular by rotating, the winding device 4, the at least one tensioning cable 5 can be at least wound up and optionally also unwound in order to be able to change the tensile stress of the at least one tensioning cable 5 and thereby change or adapt the boundary or receiving volume of the ski boot 2. The winding or unwinding of the at least one tensioning cable 5 takes place by means of at least one rotatably mounted cable spool, also referred to as spool for short.Anti-rotation locks known per se, such as locking pins, release mechanisms, a rotatable and optionally axially adjustable actuating knob, and the like, can also be formed in or on the winding device 4. In particular, a winding device 4 known from the prior art, for example based on EP0056953B1, can be used as a subcomponent of the tensioning device 1.

[0034] The tensioning device 1 further comprises a support plate 3 on which the winding device 4 is fastened or can be fastened, but is preferably permanently mounted on the support plate 3, for example by means of a screw or rivet connection.

[0035] The support plate 3 comprises at least one fastening means 6 with which the support plate 3 can be permanently fastened, preferably to the outer surface of the cuff 13 and / or to the forefoot shell 21. This fastening is preferably carried out during the manufacture or assembly of the ski boot 2. To fasten the support plate 3, at least one anchoring means 7 formed on the ski boot 2 is used, which anchoring means 7 functionally corresponds to the at least one fastening means 6 on the support plate 3. The at least one anchoring means 7 on the ski boot 2 is in an alternative use or in an alternative embodiment of the ski boot 2, for example according to Fig. 1 , for fastening at least one lever-operated tensioning buckle 8 on the ski boot 2 or for fastening at least one associated component of a lever-operated tensioning buckle 8, for example a locking or toothed strip 33.

[0036] The at least one shell- or shoe-side anchoring means 7, which may in particular comprise a plurality of openings 10, is thus provided either for the permanent attachment of at least one lever-operated tensioning buckle 8 or for the permanent attachment of the support plate 3 of the tensioning device 1. The at least one corresponding fastening means 6 on the support plate 3 may comprise a plurality of openings 9 - Fig. 3 , 6 , 8 - which, in terms of position and size, correspond to one or more of the openings 10 in the sleeve 13 - Fig. 7 - or in the forefoot shell 21.

[0037] It is expedient if the anchoring means 7, which can be used for fastening two separate, lever-operated tensioning buckles 8, are alternatively used as anchoring means 7 for the support plate 3 of the tensioning device 1, as shown in the Fig. 3-8 can be seen as an example.

[0038] According to the design in the Fig. 3-8 It may be expedient if the tensioning device 1, which can preferably be attached to the cuff 13, comprises at least two first openings 9 in the support plate 3, and the at least one corresponding anchoring means 7 on the ski boot 2 or on its shell body comprises at least two second openings 10. The first and second openings 9, 10 correspond locally or positionally, so that the support plate 3 can be fastened to the ski boot 2 by means of at least one connecting means 11, for example screws or rivets. The connecting means 11, which are schematically indicated as dash-dotted lines, are preferably intended to penetrate corresponding pairs of first and second openings 9, 10 and thus permanently fasten the tensioning device 1 or its support plate 3 to the ski boot.

[0039] How best to Fig. 3As can be seen, it may be expedient if the tensioning device 1 comprises a first and a second fastening means 6 spaced apart from one another on the support plate 3, wherein these two fastening means 6 and the winding device 4 define a triangular arrangement 12 composed of three corner points on the support plate 3, as shown in Fig. 3is illustrated by dash-dotted lines. The winding device 4 is positioned at the third corner point, which is furthest away from the tip of the boot. This third corner point of the triangular arrangement 12 lies between the first and second corner points comprising the fastening means 6 for the support plate 3, when a normal to a straight line connecting the first and second corner points intersects the third corner point. Accordingly, it can be provided that the winding device 4 is further away from the tip of the boot than the two fastening means 6 for the support plate 3. This can improve the handling of the at least one tensioning cable 5 of the winding device 4 for the user of the ski boot 2.

[0040] Like the Fig. 5, 6As can be seen, a base plate 22 of the winding device 4 can be connected to the support plate 3 in a tear-resistant manner. This connection can be carried out in particular by means of at least one screw or rivet, for example by means of at least three screws or rivets. This force-locking connection thus exists at least between the support plate 3 and the winding device 4. Alternatively, it can be provided that this screw or rivet connection also connects the shell body of the ski boot 2, in particular the cuff 13 ( Fig. 4 ) and thus a permanent and rigid connection is formed between the base plate 22, the sleeve 13, and the support plate 3 located therebetween. This allows a high-strength attachment of the winding device 4 to the sleeve 13 to be achieved, in particular, reduced bending or shear loads on the support plate 3 can be achieved.

[0041] Again Fig. 2can be removed, at least one of the two fastening means 6 on the support plate 3 or for the support plate 3 can also be provided as an anchor point 14 for at least one end of the at least one tensioning cable 5 that is distal to the winding device 4. By means of the at least one anchor point 14, at least one force introduction point for at least one end of at least one tensioning cable 5 is created on the support plate 3. According to the example, the support plate 3 has a first and a second fastening means 6, which are also each provided as anchor points 14 for the two distal ends of a first and a second tensioning cable 5 of the winding device 4.

[0042] Based on the Fig. 5In the illustrated embodiment, it can be provided that at least one fastening means 6 on the support plate 3 or for the support plate 3 is also provided as a deflection means 23 for a tensioning cable 5 of the winding device 4, designed as a closed loop 24. According to the illustrated embodiment, the support plate 3 can have a first and a second fastening means 6, which are also each provided as a holding or deflection means 23 for a tensioning cable 5 of the winding device 4, designed as a closed loop 24. To form a robust and simple loop 24 outside the winding device 4, the tensioning cable 5 is designed as a two-stranded cable, wherein both cable strands can be wound up and unwound in the winding device 4 by means of at least one cable spool. The closed loop 24 is located outside a housing of the winding device 4.This winding device 4 can be implemented in accordance with the winding device according to EP0056953B1 and comprise only one tensioning cable, both ends of which are accommodated within the winding device.

[0043] Like the Fig. 3-6 and 8 can be removed, the support plate 3 of the tensioning device 1 can form a receiving channel 26 in an upper side 25 of the support plate 3 facing away from or away from a ski boot 2. The receiving channel 26 is provided for the relatively movable receiving or sliding mounting of partial sections of the tensioning cable 5. The receiving channel 26 extends in its longitudinal course at least partially between the first and the second fastening means 6 for the support plate 3. The receiving channel 26 can, according to the embodiment in the Fig. 3-6 be designed in a tunnel-like manner or in the form of a through hole.

[0044] According to the Fig. 8In the illustrated embodiment, the receiving channel 26 can also be designed as a slot 27 in the upper side 25 of the support plate 3, in particular in the material of the support plate 3. This slot-like receiving channel 26 enables easy insertion of a tensioning cable 5, especially when the tensioning cable 5 is arranged outside the winding device 4 as a closed loop 24 (for example according to Fig. 4 or 5). According to an expedient development, this slot 27 can be at least partially covered by at least one cover element 28 in the radial direction to the slot longitudinal axis 29. The at least one cover element 28 can be positively connected to the support plate 3 by means of at least one snap-in coupling 35. By means of a cover element 28 attached to the support plate 3, an undesired falling out of the tensioning cable 5 from the slot-shaped receiving channel 26 can be prevented. Furthermore, the cover element 28 can be connected to the support plate 3 in a hinge-like manner.

[0045] As especially in the Fig. 3-8 As can be seen, the support plate 3 of the clamping device 1 can be spatially contoured or shaped in such a way that it follows or largely follows the spatial surface contour of the ski boot 2, in particular the spatial surface contour of the cuff 13 at the intended fastening location for the support plate 3.

[0046] As particularly in the Fig. 5, 6As shown purely by way of example, the at least one fastening means 6 on the support plate 3 can comprise at least one form-fitting first coupling element 15 on the underside of the support plate 3 or in a peripheral section of the support plate 3. This at least one first coupling element 15 can be formed by at least one latching hook 16 or by another projection providing a form-fitting effect. This at least one first coupling element 15 can be brought into form-fitting engagement with at least one form-fitting second coupling element 17 on the ski boot 2, in particular on or in the cuff 13 thereof. The at least one form-fitting second coupling element 17 is preferably formed by at least one corresponding recess 18 or undercut on the ski boot 2, in particular on the cuff 13 thereof.The mutually corresponding configurations and positions are implemented in such a way that, with a positive coupling of a first and a second coupling element 15, 17, a lifting of the support plate 3 from the ski boot 2 or from its cuff 13 is prevented or held back.

[0047] In the Fig. 2-5 Embodiments of load distribution elements 19 are shown, which can be referred to as subcomponents of the at least one fastening means 6 for the support plate 3. In particular, at least one shim or pressure distribution plate can be assigned to the at least one fastening means 6. The at least one load distribution element 19 is designed such that it contributes to increasing the dimensional stability of the support plate 3 in its at least one fastening section relative to a ski boot 2, in particular relative to its cuff 13.

[0048] As a summary of the Figs. 5 and 6 or the Fig. 5 and 8 can be removed, the support plate 3 can have or form a recess 20 on its upper side 25 closest to the winding device 4.
