Description

The invention relates to a sports shoe, in particular winter sports, ski or touring shoes, with a substantially rigid shoe shell and a shaft sleeve articulated thereon in the ankle area, adjusting elements for adjusting a lateral tilting of the shaft sleeve relative to the shoe shell being arranged at an articulation point of the shaft sleeve.

Sports shoes of the type mentioned designed as ski shoes are known, for example, from US Pat. No. 4,601,118 and also from EP-A1 111,472. As materials for such ski shoes, relatively rigid plastics are used today almost without exception, which necessitates the arrangement of swivel bearings between the shoe shell and the boot sleeve in the ankle region of the foot of the person wearing the shoe, in order to differentiate the forward and backward angles of the boot sleeve at different movement positions of the foot to be able to meet the needs of the shoe wearer. In order to be able to adjust the lateral cant angle between the boot collar and the shoe shell - which directly influences, for example, the ski tilt in the normal foot position of the shoe wearer - the above-mentioned adjustment elements are also provided at a linkage point of the boot boot (expediently the outer), which relate to a relative adjustment of the interacting link points allow the height of the shoe shell and the boot sleeve.

According to the two documents cited above, a clamping screw is screwed from the outside through an elongated hole-like recess of the sleeve into a threaded part fixed at the articulation point of the shoe shell to enable this tilting. After loosening this clamping screw, the shaft cuff can be moved up or down relative to the shoe shell at this one articulation point; after tightening the clamping screw, the shaft sleeve is fixed in the desired tilt position, or only around the one now modified inclination pivot axis can be pivoted back and forth.

Although the known arrangements for adjusting the cant angle of the boot collar relative to the shoe shell are sufficient for the mentioned purpose of taking into account different foot or lower leg positions of different shoe carriers, it is a major disadvantage that such adjusting elements in turn do not cause any lateral movement of the foot of the shoe carrier allow in the true sense, so that such shoes are not or only very limited use for different sports. The latter includes in particular snowboarding, in which the person wearing the sports shoe stands essentially laterally on the individual board, the balance and direction being maintained mainly by shifting the weight or center of gravity. The relatively large lateral swivels and template changes of the foot of the shoe wearer relative to the snowboard or to the sole of the shoe required for this purpose, however, cannot be carried out in the known ski boots according to the above statements, or can only be carried out against the holding action of the rigid shaft boot, which has so far mostly led to this has that advanced snowboarders were more likely to ride normal boots (moon boots), which in turn increases the risk of injury.

The object of the present invention is to improve a sports shoe of the type mentioned in such a way that the disadvantages mentioned of known shoes of this type do not occur, and in particular also those sports in which an alternating lateral tilting of the foot of the shoe wearer relative to the shoe sole is required, such as in particular the aforementioned snowboarding, while at the same time maintaining the other advantages of a shoe consisting of rigid shell parts, should be executable.

This is achieved in accordance with the present invention in that, especially for using the sports shoe as a snowboard shoe, the adjusting elements have a preferably lockable open position, which also enables the shaft boot to be tilted freely between stops when the sports shoe is used. This is now immediately achieved that the free canting of the shaft cuff compared to the shoe shell is also possible when using the sports shoe, without the risk that the adjusting elements or their parts were lost or, for example, due to self-opening clamping elements, conditions occur in which the relative movements between the boot collar and the shoe shell can lead to damage to the adjusting elements or to dirt or the like which impair the use of the sports shoe. It is easy to see, for example, that the toothed plate elements provided for the safe adjustment or re-locking of the shaft sleeves according to the two publications mentioned at the outset would be damaged within a very short time if the clamping screws provided there were not simply tightened when the sports shoe was used.

With this embodiment according to the invention it can now be fixed, for example for snowboarding, the front shoe in the direction of travel to a certain tilt that is comfortable for the respective foot position of the user, whereas the rear shoe in the direction of travel can be set in the open position of the setting elements for the tilting remains, whereby largely free movements of the snowboard rider remain possible for the necessary changes in the center of gravity.

According to a preferred embodiment of the invention it is provided that the stops of the adjusting elements are elastic, in particular made of rubber or plastic or spring elements. In a central area of the possible tilting of the shaft sleeve, the movement of the adjusting elements is thus not impeded at all; Elastic limits then act at the upper and lower ends of the possible movement between the stops, so that the actual end stops are not experienced abruptly and the respective compensating movement is hard limiting, but rather is experienced in a resiliently elastic manner.

In a further embodiment of the invention, the cant angle until the stop associated with a canting of the shaft sleeve becomes effective is less than the cant angle for a cant inward, which on the one hand (inward) enables unobstructed canting and at the same time the injury injury drive limited by too large canting to the outside.

According to a particularly preferred embodiment of the invention, the adjusting elements can comprise a sliding window inserted into the shoe shell and a clamping device arranged on the shaft sleeve, the clamping device having a locking device which is guided essentially vertically in the sliding window and can be actuated from the outside. The arrangement of the sliding window on the inside of the shoe shell overlapped by the shaft sleeve provides a certain coverage of the recess of the sliding window which enables free movement, which largely prevents contamination or the penetration of snow and the like.

In the latter context, according to a further embodiment of the invention, it is provided that the locking device has a threaded rod connected to the handle and a clamping part screwed onto this threaded rod from the inside of the shoe, which consists of a non-rotatably guided attachment part in the cutout of the sliding window and one from the inside of the shoe there is a clamping plate at the edge of the cutout. The effect of the clamping device is thus essentially reduced to the exertion of tensile forces or the resulting compression of the components lying between them; in the open position of the clamping device or the adjusting elements, the attachment part slides in the cutout of the sliding window between the upper and lower stop, so that even larger dynamic loads occurring can be easily absorbed.

In a further embodiment of the invention, the threaded rod can push through the shaft sleeve in a spacer element, which also ensures a significantly improved durability of the adjusting elements on this side, in particular in connection with the use of the sports shoe in the open position thereof.

The stops already mentioned above for limiting the free pivoting of the shaft sleeve relative to the shoe shell are arranged in a further embodiment of the invention in the upper and lower region of the cutout of the sliding window, which enables simple configuration and assembly of the adjusting elements and a direct one Interaction of the attachment part of the clamping part screwed onto the threaded rod with these stops ensures.

According to a further embodiment of the invention, the handle can be locked in any clamping position and in at least one open position of the clamping device, it being irrelevant whether this locking takes place by determining the relative position of the handle with respect to parts of the clamping device itself or with respect to surrounding shoe parts . For example, a slightly protruding nose can be provided on the outside of the shaft collar, which cooperates with an annular groove on the rear of the handle and engages there in the open position in a detent-like recess. However, it would also be possible to ensure that the thread jams itself in the extension after a certain rotation of the threaded rod in the open direction.

In order to enable an adjustment for the swiveling range of the shank cuff that influences the template in a forward and backward manner in spite of the shaft cuff, which can be tilted strongly to the side, in a further development of the invention, an adjustment device for the swiveling area is provided in the heel area, which fixes a gimbal to one of the two shoe parts Threaded rod with two screwed-on stop elements at a distance and a rotatably attached to the other shoe part, sleeve-shaped locking part which engages over the area of the threaded rod facing away from the attachment, a locking stop at the end lying between the stop elements and inside the length of the threaded rod one adapted to the associated stop element Has cross-section. In this way it is ensured that, even in the case of a threaded rod that is obliquely tilted relative to the sleeve-shaped locking part due to a laterally tilted shaft sleeve, the stop element screwed onto it can nevertheless be easily and safely adjusted in its relative position from the outside simply by rotating the locking part. Both the position of the range of possible movement in the direction of advance and the size of the possible range can thus be determined via the two separately and independently adjustable stop elements on the threaded rod, these two setting options being completely independent of one another. The cardanic fastening of the threaded rod also secures in connection with the mentioned interaction of the stop element lying within the locking part with the correspondingly designed interior of the locking part, these adjustment possibilities are completely independent of the current tilting and also pivoting of the shaft sleeve.

At least the area of the locking part which is adapted to the associated stop element in the inner cross section can, according to a preferred embodiment of the invention, consist of elastically deformable material, in particular plastic, which enables the stop element to be carried securely by means of elastic clamping thereof, even in the case of greater oblique positions between the locking part and the threaded rod.

The invention is explained in more detail below on the basis of the exemplary embodiment shown schematically in the drawing. It shows:

1 has a substantially rigid shoe shell 1 and a pivotable one in the ankle area at two articulation points 2, 3 essentially perpendicular to the plane of the illustration opened cuff 4. The shoe shell 1 also includes the sole 5; the shaft collar consists of several parts connected with closure elements to enable a central entry; these and other elements, such as tongue, inner shoe, locking arrangements, and the like, shall not be discussed further here.

It is only essential in the present context that in area II at the articulation point 3 adjustment elements 6 according to FIGS. 3 and 4 are provided, which, if necessary, either the fixed setting of a lateral tilt of the shaft sleeve 4 relative to the shoe shell 1 in the area of the arrows 7 indicated angle, or - in an open position - even when using the sports shoe allow a free tilting of the shaft sleeve 4 between stops in this angular range. This tilt is - as indicated in the upper area of FIG. 1 - outwards smaller according to arrow 8 than inwards (see arrow 9), which takes into account the fact that tilting outwards poses a greater risk of injury to the ankle of the shoe wearer .

The canting of the shaft sleeve 4 discussed in FIG. 1 is made possible by the fact that the setting elements 6 according to FIGS. 3 and 4 have a sliding window 10 inserted into the shoe shell 1 and one on the shaft sleeve 4 (omitted in FIG. 3 for the sake of clarity) Include clamping device 11. The clamping device 11 in turn has a locking device 13 which is essentially vertically guided in the cutout 12 of the sliding window 10 and has a handle 14 which can be actuated from the outside. The locking device 13 essentially consists of a threaded rod 15 connected to the handle 14 and a clamping part 16 screwed onto the threaded rod from the inside of the shoe, which in turn consists of a shoulder part 17 (for example a square or hexagon nut) guided non-rotatably in the cutout 12 of the sliding window 10. and a clamping plate 18 which is in contact with the edge of the cutout 12 from the inside of the shoe is constructed.

Stops 19 made of elastic material, such as rubber or plastic, are arranged in the upper and lower region of the cutout 12 and are held clamped in a manner that is particularly evident in FIG. 3. Depending on the hardness, size, location and the like With these stops 19 the tilt angle or the force / displacement characteristic of the tilt can be easily influenced.

From Fig. 4 it can also be seen that the threaded rod 15 passes through the shaft sleeve 4 in a spacer 20, which can also be made slightly thicker than the shaft sleeve, so that the handle 14 does not rub against the sleeve.

If the upper part 21 of the handle 14 in FIG. 3 is folded out in the direction of the arrow 22 in accordance with the broken line in FIG. 2, the shoe wearer can also twist the handle 14 and thus the threaded rod 15 slightly according to the arrows 23, for example with thick winter gloves . According to FIG. 4, as a result of the attachment part 17, which is held in the cutout 12 in a rotationally fixed manner, the latter, together with the clamping plate 18, is either pulled to bear against the inner edge of the cutout 12 of the sliding window 10 or, as shown in FIG. 4, is lifted off the latter. In the raised position, in which the handle 14 can be locked in its "open position" in a manner not shown here - the clamping part 16 and the shaft sleeve 4 connected therewith via the threaded rod 15 and the spacer element 20 are free in the vertical direction movable to the shoe shell 1, which corresponds to the mentioned free pivotability of the shaft cuff 4 as a whole. On the other hand, the clamping plate 18 can also be braced in relation to the sliding window 10 by appropriately tightening the handle 14 in any relative position between the boot collar 4 and the shoe shell 1, which results in a permanently set tilt.

3 and 4, a nose-like projection 37 is provided on the shaft sleeve 4 behind the handle 14, which has an annular groove 38 on the side of the base part of the handle facing the shaft sleeve, in order to enable the adjustment elements 6 to be locked in particular in the open position 14 is engaged. In the open position of the setting elements 6, or when the handle 14 is screwed on, this extension 37 can be brought into engagement with a narrowed point 39 of the groove 38, whereupon the locking in the open position is given. Deviating from this, however, would be other measures familiar to the person skilled in the art to ensure a corresponding one Definition of the setting device applicable in the different positions.

In all possible positions of the clamping device 11 or the clamping part 16, the elastic stops 19 are prevented on the one hand by the shaft sleeve 4 and on the other hand by the clamping plate 18 from the lateral exit from the sliding window 10.

Apart from the illustrated embodiments, individual parts of the setting elements themselves could of course also be designed differently - it is essential to enable the boot sleeve 4 to pivot freely relative to the shoe shell 1 - in particular, handles other than those shown can be used, or setting elements 6 on both sides if necessary of the shoe are provided.

5 is in turn to be used as a ski shoe or in particular as a snowboard shoe and consists of an essentially rigid shoe shell 1 and a shaft sleeve 4 articulated thereon in the ankle area. This shaft sleeve 4 is due to its articulation on the Position 3 can be pivoted forwards or backwards in the direction of arrows 24 relative to shoe shell 1 and - due to the possibility of moving the cuff area at position 3 in the direction of arrows 25 relative to shoe shell 1, again not shown here - from the side can be tilted at the level of the display.

In the heel area 26 there is an adjustment device for the theoretically possible swivel angle (double arrow 28) between the boot sleeve 4 and the shoe shell 1, which allows adjustment of the template itself and of the possible range of movement in the direction of the forward movement and is designated by 27 via two stop elements 29, 30.

The setting device 27 is shown enlarged in FIG. 6, detached from the surroundings in the shoe, and comprises a gimbal-mounted threaded rod 32 in the area of an eyelet 31 on the shoe shell 1 with the two stop elements 29, 30 screwed on at a distance, and one rotatably on the shaft sleeve 4 attached, sleeve-shaped locking part 33. The locking part 33, for example made of plastic, encompasses the area of the threaded rod 32 facing away from the attachment to the eyelet 31 and has a retracted locking stop 35 at the end 34 lying between the stop elements, which is designed to run all around. The interior of the sleeve-shaped locking part 33 has, at least over the length of the threaded rod 32, a cross section adapted to the stop element 30, which is designed here as a hexagon nut, as can be seen particularly from FIG. 7.

At the end of the locking part 33 facing away from the locking stop 35, a notched handle 36 in the form of a circumferential, thickened extension is arranged, by means of which the locking part 33 can be rotated in the installed state according to FIG. 5. Since the stop element 30 is held against rotation in the interior of the locking part 33, when the handle 36 is rotated, this stop element 30 will move up or down on the threaded rod 32, which is equal to an adjustment of the front stop for the presentation of the shaft sleeve 4. The rear stop is adjusted independently of this via the stop element 29, which is in any case freely accessible from the outside and is designed here as a notched adjusting wheel. As indicated in dashed lines in Fig. 6, when the shaft sleeve 4 is tilted to the side (likewise, albeit to a lesser extent, when the same is pivoted), the threaded rod 32 is also inclined relative to the axis of the locking part 33, but this has no effect has the possibility of adjusting the stop element 30, which still remains rotatably guided according to FIG. 7 in the adapted interior of the locking part 33.

Contrary to the embodiment shown, the threaded rod and the locking part could of course also be arranged upside down on the shoe, provided that other circumstances make this necessary. It should also be pointed out here that at the upper end of the threaded rod or the surrounding inner region of the locking part in the illustration according to FIG. 6, a limitation for the adjustment path of the stop element could also be provided, as shown only in the form of a threaded end, if this is the case this is necessary to avoid screwing the parts apart. Furthermore, if necessary, a damping element, for example a rubber or plastic sleeve, could be inserted between the stop element 30 and the locking stop 35 in order to dampen the front stop for the template.
