Description

[0001] The invention relates to a buckle for a lacing device of a shoe, for example a sports shoe or ski boot, in particular a racing ski boot. The invention further relates to a lacing device for a shoe, as well as to a shoe.

[0002] The buckle comprises a base part and a grip tab, wherein the base part can be placed with its underside against a shell of a shoe and can be fastened to the shell, wherein the base part has at least one first receiving extension on its upper side facing away from the shell, and wherein a pivoting element is formed on the grip tab, wherein in an engagement position the pivoting element is at least partially engaged in the first receiving extension to form a pivotable first locking connection, or a pivotable joint arrangement, such that the grip tab can be pivoted in the engagement position by means of the pivoting element from an open engagement position into a closed engagement position.

[0003] Generic buckles are well known in the professional world and are used to adjust and fix the fit of a boot, especially a ski boot, to a user's foot.

[0004] However, the conventional buckles have the disadvantage of being relatively high, meaning they protrude from the shell. This is disadvantageous because protruding components can be knocked off or at least damaged by contact with the ground, especially with snow and rocks. This poses a significant safety risk in both ski racing and ski touring. Furthermore, the conventional buckles have the disadvantage that they open automatically, or even unintentionally, especially upon contact with the ground. This, too, is extremely safety-critical and impairs comfort.

[0005] Lacing devices are also well known in the art. DE1273371B discloses a lacing device with a meandering rope. Such lacing devices make it possible to achieve a comparatively good load distribution on the user's instep.

[0006] However, the known lacing devices have the disadvantage that they cannot be sufficiently adjusted to the individual foot of a user.

[0007] DE102013112017B4 proposed a lacing device with adjustable deflection means, but this adjustability is not very user-friendly.

[0008] The object of the present invention was to overcome these disadvantages of the prior art and to provide an improved buckle, an improved lacing device and an improved shoe which can be easily adjusted individually and also offer a high degree of safety and in particular do not open or loosen accidentally.

[0009] This object is achieved by a buckle of the type mentioned at the outset in that at least one first latching projection is formed on the upper side of the base part, and in that the gripping tab is formed with at least one latching element corresponding to the first latching projection, wherein the first latching projection and the latching element are designed such that in the closed engagement position the latching element is at least partially latched onto the first latching projection to form a releasable second latching connection, so that the gripping tab is secured in the closed engagement position against leaving the engagement position and against pivoting, in particular against automatic or unintentional pivoting, into the open engagement position.

[0010] Such a buckle enables safe use because the double locking mechanism in the closed engagement position prevents accidental lifting, loosening, or pivoting into the open engagement position, or even completely out of the engagement position. Furthermore, the first locking connection in the open engagement position allows for pre-fixation, making it even more difficult to accidentally leave the open engagement position. This type of buckle is therefore not only extremely comfortable to use, but also extremely safe.

[0011] The engagement of the latching element of the grip tab with the locking projection on the base part enables an extremely low overall height of the buckle in the closed state. Preferably, the overall height of the buckle in the closed state corresponds at least substantially to the overall height of the base part with its first receiving projection and first locking projection protruding from the top. Such a low overall height is advantageous because it prevents or at least reduces the risk of bumping into or threading into edges, the floor or the like. Preferably, the overall height of the buckle in the closed engaged position is a maximum of 1.5 cm, preferably a maximum of 1.3 cm, particularly preferably a maximum of 1.0 cm. Such low overall heights have previously only been possible with deflection devices for deflecting traction devices up to ropes.

[0012] According to an advantageous further development, the grip tab can be designed with a passage, wherein the passage is arranged to run at least substantially parallel to a pivot axis of the pivot element, and wherein the passage is designed for, in particular, permanent or non-detachable or non-unthreadable reception and deflection of a rope- or band-shaped traction means of a lacing device.

[0013] Preferably, a traction device can be permanently incorporated into the bushing so that it cannot be unintentionally unthreaded.

[0014] According to an advantageous development, the passage can be formed in the region of the pivoting element, or in the pivoting element, or in a sleeve in the pivoting element. Thus, when pivoting in the engaged position from the open to the closed engagement position, the tensioning path traveled by the tensioning means during pivoting is comparatively small. This makes the buckle ideal for fine adjustment or pre-adjustment. Such a buckle can be designed in a lacing device as the first buckle or as one of the first buckles to be closed.

[0015] Alternatively, the feedthrough can be arranged at a radial distance from the pivoting element or from a pivot axis of the pivoting element, in particular in a sleeve. For example, the feedthrough can be arranged at a distance from the pivoting element, for example centrally or essentially centrally in the grip tab. This means that when pivoting in the engaged position from the open to the closed engaged position, the tensioning path covered by the tensioning means is comparatively large. This makes the buckle ideal for use, in particular, for a final coarse adjustment. Such a buckle can be designed in a lacing device as the last buckle to be closed. When opening such a buckle, pivoting into the open engaged position causes a comparatively large loosening, so that a user can return to a loosened resting or engaged position with a single lever movement.can reach the pause position.

[0016] According to an advantageous further development, the leadthrough, or the pivoting element in the region of the leadthrough, or the sleeve may be formed from an electrically non-conductive material, in particular from plastic, and the remaining part of the grip tab may be formed from an electrically conductive material, in particular from aluminum.

[0017] This is particularly advantageous when the buckle is used in a lacing device and when the tensioning means, which can be arranged in the bushing, is made of an electrically conductive material, for example a steel cable that is not plasticized or coated with plastic, the electrically non-conductive bushing can provide potential separation from the remaining, electrically conductive part of the grip tab. This prevents corrosion caused by potential differences between the tensioning means and the grip tab. A grip tab made from a material combination of an electrically non-conductive bushing and an electrically conductive, particularly metallic, grip part combines the advantages of corrosion resistance and stability, thus improving service life.While coated steel cables also offer improved corrosion resistance when new, they are susceptible to wear and tear because the plastic used to coat them is comparatively soft. The coating can be easily damaged and can partially or completely peel off over time, meaning that even coated steel cables can subsequently experience corrosion damage.

[0018] According to an advantageous further development, the latching element can be designed as at least one opening in the gripping tab, or the latching element can be designed as a bolt in the gripping tab.

[0019] Both variants enable or encourage a particularly flat or low height of the buckle and thus increase safety.

[0020] According to an advantageous development, a second receiving extension and a second locking extension may be formed on the upper side of the base part, wherein the second receiving extension and the first locking extension are formed on the same extension. It goes without saying that additional receiving and locking extensions may also be formed.

[0021] This allows additional adjustment positions to be created, thus further improving the adjustability and comfort of a shoe equipped with such a buckle.

[0022] According to an advantageous further development, a toothed strip can be formed by the first locking projection and the second locking projection and optionally by further locking projections.

[0023] This allows additional adjustment positions to be created, thus further improving the adjustability and comfort of a shoe equipped with such a buckle.

[0024] A toothed strip can also be designed in multiple parts, for example with mutually facing, movable and / or elastic toothings. A toothed strip can consist of two or more components, wherein a slightly movable inner part of the toothed strip can be arranged in a toothed strip outer part. Particularly when the locking element is designed as a bolt, fixation in the closed engagement position can be improved by means of a toothed strip, in particular by means of a toothed strip with elastic or movable toothings. Intermeshing toothings of a toothed strip can prevent a bolt received therein from being inadvertently lifted or levered out in the closed engagement position.

[0025] According to an advantageous further development, the base part can be one-piece and can be connected in a fixed position to a shell of a shoe, wherein the at least one first receiving extension and the at least one first locking extension are integrally formed on the base part.

[0026] Such a design is particularly simple and therefore reliable in use. Buckles with one-piece base bodies can be arranged particularly on the inner shell sections of a shoe, especially the upper shell sections.

[0027] In general, the base part can be permanently or indetachably attached to the shell of a shoe using a screw or rivet connection, for example.

[0028] Alternatively, the base part may be made up of several parts and have a first base section that can be connected in a fixed position to a shell of a shoe, wherein the first base section is coupled via a further pivoting element to a second base section that can be placed on the shell of a shoe, wherein the at least one first receiving extension and the at least one first locking extension are integrally formed on the second base section.

[0029] Such a design can offer numerous adjustment options and positions, making it easier to put on a shoe. Furthermore, the two- or multi-part construction can improve pressure distribution on the shell.

[0030] Buckles with multi-part base bodies can be arranged in particular on shell sections on the outside of the foot, in particular lower shell sections, of a shoe.

[0031] According to an advantageous development, the buckle may comprise an intermediate plate, wherein the intermediate plate is arranged on the underside of the base part and can be positioned between a shell of a shoe and the base part, wherein the intermediate plate has a tongue projecting beyond the base part, wherein the tongue can be brought into direct contact with the shell.

[0032] Such an intermediate plate can serve a dual function. It can improve the even distribution of compressive forces transmitted to a shoe by a buckle and / or a traction device. It can also serve as wear protection, protecting the shell of a shoe from abrasion or chafing caused by a traction device.

[0033] The invention further relates to a lacing device for a shoe, in particular for a ski boot, which can be attached to a shell of a shoe, wherein the shell comprises a forefoot shell for receiving a user's foot, and wherein the forefoot shell has a first shell section on the inside of the foot and a second shell section on the outside of the foot. The lacing device comprises at least one buckle, a rope- or band-shaped traction means, and two anchoring points, wherein the traction means extends in a meandering shape from the anchoring points and is arranged to extend continuously through the at least one buckle.

[0034] The object of the invention is achieved by such a lacing device in that the at least one buckle is designed according to one of the claims or according to the description in this document.

[0035] To avoid unnecessary repetition, reference is made to the preceding descriptions.

[0036] According to an advantageous further development, it may be that three buckles, in particular three buckles according to one of the claims, are formed, wherein two buckles can be arranged on the first shell section, and wherein the two anchoring points and the third buckle can be arranged on the second shell section.

[0037] Advantageously, each of the three buckles functions as a deflection means, wherein one buckle can be arranged together with the anchoring points on a shell section, in particular on a lower shell section, and the other two buckles can be arranged on a second shell section, in particular on an upper shell section.

[0038] According to an advantageous development, the traction means can be guided at least in regions over the tongue of the intermediate plate and rests at least in regions on the tongue, so that a force acting from the traction means on a shell, in particular on a first shell section of a forefoot shell of a shoe on the inside of the foot, is guided and distributed via the tongue onto the shell, wherein the traction means rests on the tongue, so that there is no or only little direct contact between the shell and the traction means.

[0039] According to an advantageous further development, the intermediate plate can be formed on a buckle arranged on the first shell section, wherein the tongue of the intermediate plate extends to an outer edge or at least to a region close to the outer edge of the first shell section.

[0040] Preferably, the tongue does not overlap the first shell section, but extends only to the edge or outer edge of the first shell section. The distance between the outer edge and the tongue can be between 0 and 1.5 cm, preferably between 0 and 1 cm, in particular between 0 and 0.5 cm.

[0041] According to an advantageous further development, a buckle can be fastened to the second shell section, wherein the base part, in particular the second base part section, extends over an instep area up to the first shell section.

[0042] According to an advantageous further development, the rope- or band-shaped traction means may be formed from an electrically conductive material or have an electrically conductive surface.

[0043] According to an advantageous further development, at least one of the anchoring points can be designed with a, in particular continuously adjustable, fine or fine stone adjustment device, by means of which a length of the traction means can be changed.

[0044] With such a fine or micro-adjustment device, the length of the tensioning mechanism can be slightly lengthened or shortened, allowing the fit of the shoe to be further optimized when the lacing is closed. In this context, fine or micro-adjustment refers to a small adjustment range compared to the position change achieved by adopting different locking positions in a multi-stage buckle. The fine or micro-adjustment device can achieve continuous adjustment in the single-digit millimeter range. Such a continuous micro-adjustment device can be designed, for example, with a screw or an eccentric.

[0045] The invention further relates to a shoe, in particular a ski boot, with a shell, in particular a hard shell, comprising a forefoot shell for receiving a user's foot, wherein the forefoot shell has a first shell section on the inside of the foot and a second shell section on the outside of the foot, wherein the first shell section and the second shell section are spaced apart from one another in an instep region, or wherein the first shell section is designed as an upper shell section and the second shell section is designed as a lower shell section, and the first shell section at least partially overlaps the second shell section starting from an inside edge of the shoe in the direction of an outside edge of the shoe in an instep region.

[0046] The object of the invention is achieved by such a shoe in that it is designed with at least one buckle according to one of the claims or according to the description in this document and / or that the shoe is designed with a lacing device according to one of the claims or according to the description in this document.

[0047] To avoid unnecessary repetition, reference is made to the preceding descriptions.

[0048] For a better understanding of the invention, it is explained in more detail using the following figures.

[0049] They show in a highly simplified, schematic representation: Fig. 1An embodiment of a shoe with a lacing system, with one buckle outside the engagement position and two buckles in the open engagement position, in a tilted frontal view, Fig. 2the shoe from Fig. 1with one buckle in the open engagement position, one buckle outside the engagement position and one buckle in the closed engagement position, in tilted frontal view, Fig. 3 the shoe from Fig. 1 with all buckles in the closed engagement position, in tilted front view, Fig. 4 an embodiment of a buckle with a one-piece base part and a grip tab, in exploded view, Fig. 5 a further embodiment of a buckle, wherein in the Fig. 5a a grip tab in view on the underside is shown and in the Fig. 5b an exploded view of the handle tab Fig. 5a and a multi-part base part, shown in top view.

[0050] 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. The disclosures contained throughout the description can be applied analogously 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 these positional information must be applied analogously to the new position in the event of a change in position.

[0051] In the Fig. 1 to 3a shoe 3, in particular a ski boot 3, is shown, wherein the ski boot 3 is preferably designed as a racing ski boot. The ski boot 3 has a shell 7, in particular a hard shell made of plastic. It would also be conceivable if the shell 7 was made of fabric, leather or comparable shoe-typical materials and if the shoe 3 was, for example, a sports shoe or a mountain boot. While it is usual for the shell 7 or hard shell in ski boots 3 to be an outer shell, wherein an inner shoe can be arranged in the outer shell, such a multi-part shell arrangement is rather unusual for sports or mountain boots, although equally conceivable.

[0052] It goes without saying that the ski boot 3 shown is only one possible embodiment representative of a multitude of conceivable designs and the invention is in no way limited to the design shown in the figure or to this intended use.

[0053] The boot 3 comprises a forefoot shell 31 for receiving a user's foot, wherein the forefoot shell 31 has a first shell section 32 on the inside of the foot and a second shell section 33 on the outside of the foot. Ski boots 3 typically also have an additional shell area for receiving the ankle and at least part of a user's lower leg, as is known per se. Sports or mountaineering boots can also be designed as low shoes, as is known per se.

[0054] The first shell section 32 on the inside of the foot and the second shell section 33 on the outside of the foot of the forefoot shell 31 can be spaced apart from each other in an instep area. This variant is not shown in the figure, but is known in particular from ski touring boots, for example from EP3153047B1, or mountaineering boots.

[0055] Alternatively and in the Fig. 1 to 3 The first shell section 32 is shown as an upper shell section, and the second shell section 33 is shown as a lower shell section. Starting from an inner edge 34 of the shoe in the direction of an outer edge 35 of the shoe, the first shell section 32 overlaps the second shell section 33 at least partially in an overlap region in an instep area. In principle, a reverse overlap is also conceivable, with the first shell section 32 being formed as a lower shell section and the second shell section 33 being formed as an upper shell section.

[0056] The exemplary embodiment of the shoe 3 is designed with a lacing device 2 on its forefoot shell 31. The lacing device 2 comprises at least one buckle 1, a rope- or band-shaped tensioning means 18, in particular an unsheathed steel cable, and two anchoring points 30 or two fixed points to which the two ends of the tensioning means 18 are attached. The tensioning means 18 extends in a meandering shape from the anchoring points 30 and is arranged continuously through the at least one buckle 1.

[0057] By means of the two anchoring points 30, the traction means 18 can be fixed at both its ends and thus permanently connected to the shell 7 of the shoe 3. The anchoring points 30 can be fixed to the shell 7 in a non-detachable manner, for example by rivets, but also detachably, for example by means of a screw connection. At least one of the anchoring points 30 can be designed with a, in particular continuously adjustable, fine or micro-adjusting device, by means of which the length of the traction means 18 can be changed. This can be a device for micro-adjustment or fine adjustment of the tension and length of the traction means 18. Various mechanisms are conceivable here; for example, such a fine or micro-adjusting device can be actuated by means of a screw or an eccentric.

[0058] Different designs, views and positions of the buckle 1 are shown in the Fig. 1 to 5bshown. In all embodiments, the buckle 1 comprises a base part 4 and a grip tab 8. The base part 4 can be placed with its underside 5 on a shell 7 of a shoe 3 and can be fastened to the shell 7. In the Fig. 1 to 3 the base part 4 is attached to the first shell section 32 or the second shell section 33 of the forefoot shell 31. The attachment is in all Fig. 1 to 3 using a screw. Of course, all other common fastening methods are also possible, such as rivets.

[0059] The base parts 4 of the buckles 1 shown have at least one first receiving extension 9 on their upper side 6. A pivoting element 10 is formed on each of the grip tabs 8. In an engagement position 11, the pivoting element 10 is at least partially engaged in the first receiving extension 9 to form a pivotable first locking connection, so that the grip tab 8 can be pivoted in the engagement position 11 by means of the pivoting element 10 from an open engagement position 12 to a closed engagement position 13.

[0060] It is further provided that at least one first latching extension 14 is formed on the upper side 6 of the base part 4, and that the gripping tab 8 is formed with at least one latching element 15 corresponding to the first latching extension 14, wherein the first latching extension 14 and the latching element 15 are designed such that in the closed engagement position 13, the latching element 15 is at least partially latched onto the first latching extension 14 to form a releasable second latching connection. The gripping tab 8 is thus secured in the closed engagement position 13 against inadvertent or unwanted departure from the engagement position 11 and against pivoting into the open engagement position 12. In the closed engagement position 13, when both the first and the second latching connection are assumed, the gripping tab 8 can only be released by deliberately applying a force to the underside of the gripping tab 8.

[0061] In the Fig. 1 to 3 the lacing device 2 is designed with three such buckles 1. In the Fig. 1 In the case of the first buckle 1, which is closest to a toe area of ​​the shoe 3, the pivoting element 10 is engaged in the first receiving extension 9 to form the first locking connection and is in the open engagement position 12. Likewise, the second or middle of the buckles 1 shown is engaged in the first receiving extension 9 to form the first locking connection and is in the open engagement position 12. In the case of the third buckle 1, which is furthest away from the toe area of ​​the shoe 3, the pivoting element 10 is not engaged in the first receiving extension 9 and is shown in its released position.

[0062] In the Fig. 2In the first buckle 1, which is closest to a toe area of ​​the shoe 3, the pivoting element 10 is engaged in the first receiving extension 9 to form the detachable and pivotable first locking connection. In addition, in this first buckle 1, the locking element 15 is now at least partially engaged on the first locking extension 14 to form the detachable second locking connection. Thus, this first buckle 1 now assumes the first and second locking connections simultaneously and is thus in its closed engagement position 13. The second or middle buckle 1 is in the Fig. 1threaded, i.e., the pivoting element 10 is not engaged in the first receiving extension 9 and is shown in its released position. In the third buckle 1, which is the one furthest away from the toe area of ​​the shoe 3, the pivoting element 10 is engaged in a second receiving extension 22 to form the detachable and pivotable first locking connection and is in the open engagement position 12.

[0063] In the Fig. 3 all three buckles 1 are shown in their closed engagement position 13, wherein in the first and second buckle 1 the pivoting element 10 is each engaged in the first receiving extension 9 and in the third buckle 1 the pivoting element 10 is engaged in the second receiving extension 22.

[0064] The in the embodiment according to the Fig. 1 to 3 The buckles 1 shown are also shown in detail in the Fig. 4 and 5a and 5b shown below. Fig. 1 to 5bare now described in summary to avoid unnecessary repetition. Special features of individual designs or representations are referred to separately in the respective figure. In addition, the Fig. 1 to 3 Numbering of the three buckles 1 is also retained below.

[0065] It may be that the grip tab 8 is formed with a passage 16, wherein the passage 16 is arranged at least substantially parallel to a pivot axis 17 of the pivot element 10, and wherein the passage 16 is designed to receive and deflect the rope- or band-shaped traction means 18 of the lacing device 2. It is not absolutely necessary that the passage 16 is closed over its entire axial length. Fig. 3 It is clearly visible that the bushings 16 are open on one side and thus the traction means 18 is also visible in the area of ​​the bushing 16.

[0066] It is also possible for the passage 16 to be formed in the region of the pivoting element 10, or in the pivoting element 10, or in a sleeve 19 in the pivoting element 10. The passage 16 may be at least substantially congruent or identical with the pivot axis 17 of the pivoting element 10. This is the case, for example, according to the first and third buckles in the Fig. 1 to 3 , as well as in the Fig. 4 .

[0067] Alternatively, the passage 16 may be arranged at a distance from the pivoting element 10, in particular in a sleeve 19. In this case, the passage 16 may be spaced from the pivot axis 17 of the pivoting element 10. This is possible, for example, according to the second buckle in the Fig. 1 to 3 , as well as in the Fig. 5a and 5b .

[0068] It may also be the case that the passage 16, or the pivoting element 10 in the area of ​​the passage 16, or the sleeve 19 is made of an electrically non-conductive material, in particular plastic, and that the remaining part of the grip tab 8 is made of an electrically conductive material, in particular aluminum. In the first and third buckles in the Fig. 1 to 3 , as well as at buckle 1 in the Fig. 4 The grip tab 8 is a one-piece composite component with a plastic bushing 16 and a remaining part made of metal, in particular aluminum. In the second buckle 1 in the Fig. 1 to 3 , as well as in the Fig. 5a and 5b the grip tab 8 is a multi-part component with a grip tab 8 made of metal, in particular aluminum, and a sleeve 19 made of plastic that is permanently connected to it, for example, clipped on or in a form-fitting manner.

[0069] Furthermore, the rope- or band-shaped traction device 18 may be made of an electrically conductive material or have an electrically conductive surface. Advantageously, the traction device 18 is not coated with a plastic, fabric, or woven material, etc. This is because with plasticized or coated steel cables, no visual inspection of the traction device 18 or steel cable for any damage is possible. Furthermore, sheathing is comparatively soft and can therefore be easily damaged and partially or even completely detached.

[0070] Furthermore, it may be that the locking element 15, as in the first and third buckle 1, is in the Fig. 1 to 3 , as well as at buckle 1 in the Fig. 4 as at least one opening 20 is formed in the grip tab 8.

[0071] Alternatively, the locking element 15 may be inserted into the Fig. 1 to 3 , as well as in the Fig. 5a and 5bas a bolt 21 in the grip tab 8. In this embodiment, it is shown that, independently of this, the pivoting element 10 can also be designed as a bolt.

[0072] It may also be that a second receiving extension 22 and a second locking extension 23 are formed on the upper side 6 of the base part 4, wherein the second receiving extension 22 and the first locking extension 14 are formed on the same extension.

[0073] It is also possible that a toothed strip 24 is formed by the first locking projection 14 and the second locking projection 23 and optionally by further locking projections. This variant is shown in the second buckle 1 in the Fig. 1 to 3 , as well as in the Fig. 5a and 5bshown. A toothed strip 24 can also be designed in several parts, for example with mutually facing displaceable and / or elastic toothings. A toothed strip 24 can consist of two or more components, wherein a slightly displaceable toothed strip inner part can be arranged in a toothed strip outer part. In the second base part section 27 in the Fig. 5b It is illustrated that the toothed rack 24 can consist of two or more components, wherein a slightly displaceable inner toothed rack part can be arranged within a toothed rack outer part. In this example, the inner toothed rack part is inserted from below into the frame-like outer toothed rack part. The inner toothed rack part has a clearance on its underside relative to the outer toothed rack part, which allows displacement or movement in the radial direction relative to the pivot axis 17.

[0074] Particularly when the locking element 15 is designed as a bolt 21, a toothed strip 24, in particular a toothed strip 24 with elastic or movable teeth, can improve fixation in the second locking position or in the closed engagement position 13. Interlocking teeth of a toothed strip 24 can prevent a bolt 21 received therein from being inadvertently lifted or levered out in the closed engagement position 13.

[0075] It may also be the case that the base part 4 is one-piece and can be connected in a fixed position to a shell 7 of a shoe 3, wherein the at least one first receiving extension 9 and the at least one first locking extension 14 are integrally formed, i.e., virtually in one casting, on the base part 4. This variant is used for the first and third buckle 1 in the Fig. 1 to 3 , as well as at buckle 1 in the Fig. 4 shown.

[0076] Alternatively, it may be that according to the second buckle 1 in the Fig. 1 to 3 , as well as in the Fig. 5a and 5b the base part 4 is multi-part and has a first base section 25 which can be connected in a fixed position to a shell 7 of a shoe 3, wherein the first base section 25 is coupled via a further pivot element 26 to a second base section 27 which can be placed against the shell 7 of a shoe 3, wherein the at least one first receiving extension 9 and the at least one first locking extension 14 are integrally formed on the second base section 27. The further pivot element 26 can be designed as a part or region of the second base section 27, together with the first base section 25 forming a further joint arrangement. It is also possible that within this further joint arrangement a spring element (not shown in detail), for example a

[0077] Spiral spring, with a predefined preload. Such a spring element can be designed to press the second base section 27 toward the shell 7, thus ensuring improved seating and good contact.

[0078] It may also be that the buckle 1 as shown in the Fig. 1 to 3 , as well as in the Fig. 4 shown comprises an intermediate plate 28, wherein the intermediate plate 28 is arranged on the underside 5 of the base part 4 and can be positioned between a shell 7 of a shoe 3 and the base part 4, wherein the intermediate plate 28 has a tongue 29 projecting beyond the base part 4, wherein the tongue 29 can be brought into direct contact with the shell 7. The functionality of the tongue 29 is particularly evident from the Fig. 1 to 3clear. In this case, the traction means 18 is guided over the tongue 29 and thus does not come into direct contact with the shell 7, or only in certain areas. The tongue 29 extends at least almost to the edge of the overlapping first shell section 32. Due to the stepped transition from the first shell section 32 to the second shell section 33, it is possible that the traction means 18 does not come into contact with the second shell section 33, or only comes into contact to a small extent, or at least with a reduced pressure force. Also conceivable, but not shown in the figure, is a tongue 29 with a guide groove for the traction means 18. Of course, such a tongue 29 can also be useful in a shoe 3 in which the shell sections 32, 33 are spaced apart from one another.

[0079] It is thus possible for the traction means 18 to be guided at least partially over the tongue 29 of the intermediate plate 28 and to rest at least partially on the tongue 29, such that a force acting from the traction means 18 on a shell 7, in particular on a first shell section 32 of a forefoot shell 31 of a shoe 3 on the inside of the foot, is guided and distributed via the tongue 29 onto the shell 7. The traction means 18 can rest on the tongue 29, such that there is no direct contact between the shell 7 and the traction means 18. Since the tongue 29 can also serve as wear protection for the shell 7, it can, for example, be designed to be replaceable as a spare part. Alternatively or additionally, the intermediate plate 28 can also be made of a harder or more abrasion-resistant material than the shell 7.

[0080] It may be that the intermediate plate 28 is formed on a buckle 1 arranged on the first shell section 32, wherein the tongue 29 of the intermediate plate 28 extends to an outer edge or at least to a near region of the outer edge of the first shell section 32.

[0081] As in the Fig. 1 to 3 As shown, it may be that a buckle 1 is attached to the second shell section 33, wherein the base part 4, in particular the second base section 27, extends over an instep area up to the first shell section 32. This in the Fig. 1 to 3 The middle or second buckle 1 shown extends from the second shell section 33 over the edge or the outer edge of the first shell section 32, thus overlapping the overlapping area of ​​the shell sections 32, 33. This can be expedient in combination with a two-part or multi-part design of the base part 4.

[0082] When putting on a shoe 3 with the buckle arrangement and lacing device 2 according to the Fig. 1 to 3 can be done as follows.

[0083] In order for a user to be able to comfortably step into the shoe 3 with his foot or forefoot, it can be expedient if all buckles 1 are initially unthreaded, i.e., not in the engagement position 11. Even if all grip tabs 8 are not in the first locking connection, they are attached to the lacing device 2, or rather to the shoe 3, by means of the traction means 18 and thus cannot be lost. If individual buckles 1 are left in the engagement position 11, they are preferably in the open engagement position 12 and not in the closed engagement position 13, as this would prevent the shell sections 32, 33 from being pushed apart. Preferably, the middle or second buckle 1 is in the open engagement position 12 when stepping into the shoe 3, and the first and third identical buckles 1 are each completely unthreaded, i.e., the grip tab 8 is detached from the base part 4. A next step is Fig. 1illustrated. As soon as the user's foot is in the shoe 3, the first and third buckles 1 are first moved into their respective open engagement position 12. The first and third buckles 1 function as a means for presetting a pretension of the traction means 18, or of the steel cable. For this purpose, the first and third buckles 1 can have one or more adjustment positions, i.e. one, two or more receiving extensions. For this purpose, it can be sufficient if a tension or a tensile force that occurs when the grip tab 8 is closed or when the grip tab 8 is pivoted into the closed engagement position 13 is comparatively low. This means that the lever movement only causes a comparatively small change in the position of the traction means 18. For this purpose, the feedthrough 16 can be formed in the region of the pivoting element 10, or in the pivoting element 10, or in a sleeve 19 in the pivoting element 10.The passage 16 can be at least substantially congruent or identical to the pivot axis 17 of the pivot element 10. Because the first and third buckles 1 are doubly secured against unintentional release or opening, particularly during use, in their closed engagement position by establishing a first locking connection and a second locking connection, this presetting can be maintained throughout the entire service life.

[0084] A user now only has to move the grip tab 8 of the second or middle buckle 1 into the desired engagement position 11 in the toothed rack 24. The adjustment path or the tensile force that is covered or applied by pivoting or closing the grip tab 8 of the second or middle buckle 1 can be comparatively greater than that previously applied by the first and third pre-adjustment buckle 1. This allows the second or middle buckle 1 to function as the main buckle 1, and with just one handle or just one lever movement of the grip tab 8 of the second or middle buckle 1, the shoe 3 can be brought from a loosened, locked state to a tightened, use state. For this purpose, the passage 16 can be arranged at a distance from the pivot element 10. The passage 16 can be spaced from the pivot axis 17 of the pivot element 10.The radial distance between the pivot axis 17 and the bushing 16 corresponds to the tensioning path of the traction means 18 when pivoting from the open engagement position 12 to the closed engagement position 13.

[0085] In an operational state, as in the Fig. 3 shown, all buckles 1 are closed. If desired, for example during a break while skiing, the user can bring about a considerable loosening of the cable pull or the tensile force of the traction means 18 by pivoting the grip tab 8 of the second or middle buckle 1 into the open engagement position 12.
