Device for adjusting the side inclination of a shoe upper of a sports shoe

The invention relates to a device for adjusting the side inclination of a shoe upper part of a sports shoe, which is pivotably mounted on a shell-shaped shoe lower part by means of pivot pins in the longitudinal direction of the shoe, with at least one actuator movably mounted on one of the shoe parts for height adjustment of at least one long side of the shoe. Upper part in different height positions relative to the lower part of the shoe, and with a clamping device, with the help of which the upper part of the shoe can be locked on the lower part of the shoe in the set height position.

Such a device is used in particular in a ski shoe, ice skate or roller skate, and the lower part of the shoe is in particular a rigid shell or lower shell made of plastic, whereas the upper part of the shoe (also made of plastic) is a shaft or a cuff , but can also act a tailgate.

From DE 39 19 430 AI a device for adjusting the side inclination (so-called. Canting) of a shaft of a ski boot is known, in which a toothed segment is fixedly arranged in the shaft, in which a toothed roller engages as an actuator, which is fixed but rotatable in the shoe shell is stored. The toothed roller is mounted on a pull pin provided as a hinge pin, which is rotatably mounted in the shoe shell; a lever articulated on the draw bolt enables on the one hand a height adjustment of the shaft relative to the shoe shell by twisting and on the other hand also a fixation of this adjusted height position by clamping. This arrangement is intended to achieve a gradual adjustment of the inclination of the shoe upper. In practice, however, only a rough adjustment of the height position of the shoe upper relative to the shoe shell can be achieved by the direct translation between the toothed roller and the toothed segment. In addition, with this arrangement, restoring forces, due to material stresses during a one-sided height adjustment, which occur primarily in the shoe upper, can have a disadvantageous effect on a desired fine adjustment. Furthermore, a device for adapting the side inclination of a cuff relative to a shell of a ski boot was proposed in EP 0 111 472 A1, in which an elongated hole is provided in the side of the cuff, which is penetrated by a tension member. An intermediate piece is pressed against the outside of the sleeve via a head of the tension member, a height adjustment being made possible depending on the position of the intermediate piece relative to the longitudinal direction of the elongated hole. Similar devices for lateral inclination adjustment based on mere clamping are known from US Pat. No. 4,567,617 A and EP 0 570 053 AI. These devices also do not allow a "real" controlled fine adjustment of the height position of the upper (namely the cuff) relative to the lower part (the shell).

Furthermore, from FR 2 682 570 AI a device for adjusting the side inclination of a shaft of a ski shoe relative to the boot shell is known, in which the pivot point of the shaft lies in the heel area and a tilting bearing is provided for the shaft in this area. Eccentric canting adjustment devices arranged on both sides of the ankle section in turn allow only a rough adjustment of the side inclination of the shaft relative to the shell.

In a similar way, only a rough lateral inclination adjustment is possible in the device according to DE 33 19 749 AI, which permits adjustment in only a few discrete adjustment positions. It is also disadvantageous here that small bearing bodies with intermediate latches which are to be produced with narrow tolerances are required in this device.

It is an object of the present invention to provide a device of the type mentioned at the outset, with the aid of which a precise and stepless adjustment of the side inclination of the upper part of the shoe relative to the lower part of the shoe and a stable fixation in this set position is made possible, with restoring forces also occurring should not come into effect before the determination with the help of the clamping device

To achieve this object, it is provided according to the invention that the at least one actuator has at least one control surface which bears against the hinge pin of this longitudinal side of the shoe and which is used for height adjustment of the upper of the shoe under one Angle to the direction of movement of the actuator. Since this design corresponds to an "inclined plane" or "wedge surface", the advantages of the latter also come into play, such as reduced effort, conversion of a horizontal force into a vertical force on the pivot pin and free choice of the slope. Here, the design of the device can be simplified or its operation can be facilitated. It is particularly advantageous that the system with the actuator, after a "canting" setting and even before the clamping device has been tightened, is able to provide sufficient resistance against any restoring forces so that the desired lateral inclination can be fixed exactly. It is also irrelevant whether such a side inclination adjustment device is only provided on one side of the shoe (in particular in the area of the outer ankle) or on both sides (inside and outside).

When setting the desired side inclination, the upper part of the shoe is to be moved relative to the lower part on the pivot pin in such a way that only an up or down movement (generally in the direction of the axis of the upper part) takes place. In order to ensure this in a particularly simple and reliable manner, it is expedient if a rigid cover is attached to the outside of the shoe in the region of the hinge pin and has a generally vertical elongated hole, preferably running in the direction of the upper part axis. In itself, however, it would be conceivable that a corresponding general "vertical" pivot pin guide is simply provided on the shoe part itself to which the actuator is attached (for example in the form of a groove or an elongated hole).

A structurally particularly simple and expedient embodiment of the device according to the invention consists in that the actuator is plate-shaped and has a longitudinal slot, the edges of which form an upper and a lower control surface. In this way, both an upward movement and a downward movement of the upper part of the shoe relative to the lower part of the shoe can be forcibly brought about and controlled sensitively.

For the space-saving accommodation of the individual components of the "canting" device, it is particularly favorable if the actuator on the upper part of the shoe, preferably pivotable, is mounted and the hinge pin assigned to the actuator is firmly connected to the lower shoe part.

Furthermore, it is advantageous for the simple and stepless actuation of the device according to the invention if the actuator is designed as a toothed segment plate, the teeth of which mesh with a drive gear rotatably mounted on the upper part of the shoe.

As already mentioned, in the canting device according to DE 39 19 430 AI, a lever articulated on the draw bolt is provided for actuation, which is not only complex but also disadvantageous because an additional component protrudes beyond the outer surface of the shoe. In contrast, it is preferably provided according to the invention that the drive gear simply has a screwdriver slot on an outer end face of its shaft and can be actuated from the outside of the shoe by means of a screwdriver. A constructional simplification is thereby achieved, the actuation, which may not be as comparatively easy, not being important, since the side inclination is generally set only once by the respective user and then remains in this setting.

With regard to the desired self-locking, it is advantageous if the transmission ratio between the drive gear and the toothed segment plate is 1: 5 to 1:10, preferably approximately 1: 7. In this way, on the one hand, the influence of the restoring forces occurring during the adjustment is largely reduced, on the other hand, a noticeable, comfortable adjustment is made possible when the drive gear is turned.

In order to ensure stable guidance of the actuator during the adjustment movement, it is also advantageous if the plate-shaped actuator has a strip-shaped projection which is guided in a guide groove of the shoe upper during movement of the actuator.

It is also advantageous here if the strip-shaped projection is provided with a scale for visual control of the adjustment of the side inclination, which scale is accessible via a viewing opening in the bottom of the guide groove and, if appropriate, in the outer cover attached to the shoe upper part in the area of the toothed segment plate .

So that the adjustment mechanism against mechanical shocks, Impacts or effects when ramming hard surfaces of objects is effectively protected, it is also advantageous if the cover is made of metal or hard plastic.

A structurally simple and inexpensive mounting of the drive gear consists in the cover having a bore for mounting the shaft of the drive gear.

In order to achieve an even more stable position of the drive gear relative to the toothed segment plate, it is advantageous if a plate with a hole for additional mounting of the shaft of the drive gear is attached to the inside of the shoe upper.

For simple and quick assembly or disassembly of the cover, it is also advantageously provided that the cover has an extension which is inserted in a form-fitting manner in a passage of the shoe upper. With this measure, the cover is also secured against twisting relative to the upper of the shoe.

A preferred embodiment because of the particularly stable pin guide in the direction of the axis of the shoe upper is characterized in that the elongated hole is provided in the region of the extension of the cover. The slot is then in an area of great material thickness.

Furthermore, it is advantageous for the actuating movement if the longitudinal slot is designed in the form of a circular arc; it is furthermore favorable if the radius of the longitudinal arc-shaped slot is at least twice as large as that of the circularly arranged toothing of the pivotable toothed segment plate.

With regard to the desired adjustment paths or angle of rotation of the actuator and the desired self-locking, it is particularly advantageous if the angle between the control surface and the direction of movement of the actuator is between 20 ° and 45 °, preferably between 30 ° and 40 ° is.

The invention is subsequently further explained on the basis of a currently particularly preferred exemplary embodiment shown in the drawing, to which, however, it should not be limited. The drawing shows:

Fig.l a ski boot in view;

Fig.2 shows a detail of the ski boot in section along the line II-II in Fig.l, on a larger scale than Fig.l; and the

3 and 4 detailed representations of the upper of the shoe from the inside, essentially corresponding to FIG. 2, in side view, components being omitted in FIG. 3 for the sake of clarity.

Fig.l shows as an example of a sports shoe a ski boot 1 with a shoe upper (shaft or cuff, if necessary also tailgate) 2, which can be pivoted in the longitudinal direction of the shoe on a shoe lower part (shell) 3 in the ankle area on both sides by means of pivot pins 4 is stored.

As can be seen more precisely from FIG. 2, at least one of the hinge pins 4, for example that in the region of the outer ankle, is designed as a threaded sleeve 5, which at its closed end is pressed into the upper section of the shoe lower part 3 in a manner preventing rotation and secured against longitudinal displacement or cast in. A locking screw 6 is screwed into the open end of the threaded sleeve 5, the function of which is explained in more detail below. This threaded sleeve 5 passes through, from the inside, from the shoe lower part 3, going outwards (from left to right in FIG. 2), initially a preferably circular arc-shaped longitudinal slot 7 of an actuator 8 pivotably mounted in the shoe upper part 2, which as generally sector-shaped toothed segment plate 9 is formed (see FIGS. 1 and 4), and then partially the upper part 2 of the shoe. The edges 10, 11 of the longitudinal slot 7 in the actuator 8 here form an upper control surface 12 and a lower control surface 13 for the pivot pin 4 or the threaded sleeve 5, the control surfaces 12, 13 extending at an angle α to the direction of movement of the toothed segment plate 9 (which runs in a circular arc due to the pivoting movement of the toothed segment plate 9), as best shown in FIG. 4 is recognizable. At the pivot point D of the toothed segment plate 9, a bore 14 is provided therein for receiving a pin 15, which is molded onto the inside of the shoe upper 2 in the lower end section thereof.

The toothing 9 'of the toothed segment plate 9 meshes with a drive gear 16 which is rotatably mounted in the shoe upper 2 and which is integral with a shaft 17; this shaft 17 is in the direction of the outside of the shoe in a hole 18 in the shoe upper 2 recorded and provided on the outer end face with a slot 19 for attaching a screwdriver. This slot 19 is accessible via a bore 20 in a cover 21 attached to the outside of the shoe upper 2 in the region of the toothed segment plate 9, the bore 20 also serving to support the shaft 17. As a counter bearing for the shaft 17, this is rotatably mounted on the other (inner) side of the drive gear 16 in a bore 22 of a rectangular plate 25 fastened in a recess 23 on the inside of the shoe upper 2 by means of a screw 24.

It should be mentioned here that the view of the inside of the shoe upper 2 according to FIG. 3 only shows recesses, openings or bores in the shoe upper 2, while in FIG. 4 the same view, but with a toothed segment plate 9, threaded sleeve 5 etc. , represents.

The aforementioned cover 21 is made of metal or hard plastic and has in the area of the threaded sleeve 5 or locking screw 6 an inwardly protruding extension 26 which adapts to the shape of a passage 27 in the upper 2 of the shoe and is inserted therein or is inserted (Fig.2, 3); the passage 27 is designed as an elongated hole 28 which is generally aligned in the axial longitudinal direction A of the upper 2 of the shoe (corresponding to the lower leg axis). In the extension 26 itself a - somewhat smaller - slot 29 is cut out, which is also aligned in the longitudinal direction A of the shoe upper 2 and is penetrated by the threaded sleeve 5 or by the locking screw 6. The length of the threaded sleeve 5 is such that it ends at a distance from the head 30 of the locking screw 6 designed as a countersunk screw, the edge of the elongated hole 29 widening obliquely outwards in the region of the head 30 (FIG. 2), in order to enable the head 30 to slide up and down with little friction when adjusting the side inclination with the aid of the described device.

In order to also be able to visually control the adjustment of the side inclination, a strip-shaped projection 31 with a scale (not shown) is attached to the toothed segment plate 9 and runs according to a circular arc (with the center at the pivot point D of the toothed segment plate 9) when the toothed segment plate 9 moves in a circular arc Guide groove 32 of the shoe upper 2 is guided. The bottom of the guide groove 32 and the cover 26 are provided in the area of the scale below the shaft 17 with a viewing opening 33.

The radius of the circular arc-shaped longitudinal slot 7 in the toothed segment plate 9 is selected to be at least twice as large as that of the toothed segment 9 'of the toothed segment plate 9 arranged in a circular arc. The angle α (FIG. 4) between the respective control surface 12, 13 of the longitudinal slot 7 and the Direction of movement of the actuator 8 or the toothed segment plate 9 is between 20 ° and 45 °, in particular between 30 ° and 40 °.

To set the desired side inclination of the shoe upper part 2 relative to the shoe lower part 3, the locking screw 6 is first loosened somewhat by means of a screwdriver so that the head 30 lifts off from the bevelled edge region of the elongated hole 29 and thus a previously existing frictional engagement between the Tooth segment plate 9 on the one hand and the shoe upper 2 and extension 26 on the other hand is lifted and the clamping device formed by the parts 5, 6 is released. Now the shaft 17 is rotated by means of a screwdriver, as a result of which the toothed segment plate 9 is pivoted via the drive gear 16 and with the upper and lower control surfaces 12 and 13 on the threaded sleeve 5 with the locking screw 6, depending on the direction of rotation of the shaft 17 , slides and is raised or lowered over the control surfaces 12 or 13; as a result, the height position of the shoe upper 2 is adjusted on one side — with elastic material deformation in other shoe part areas — since the hinge pin 4 or the threaded sleeve 5 relative to the shoe upper 2 is in the manner of a “link guide” acting slot 29 in the longitudinal direction A of the shoe upper 2 moves up and down. If the desired setting is reached under visual control of the scale on the projection 31, the locking screw 6 is tightened again, i.e. the clamping device is reactivated in order to bring about the aforementioned frictional engagement and to fix the side inclination setting of the shoe upper 2.

In order to promote "self-locking" between the drive gear 16 and the toothed segment plate 9 during the adjustment process, in particular before and during the fixing of the adjustment by means of the locking screw 6, Settling ratio of this toothed gear 1: 5 to 1:10, preferably approximately 1: 7.

The invention has been described above with reference to a preferred embodiment in which the actuator is designed as a pivotable toothed segment plate with control surfaces. However, there is also the option of a linear, e.g. by means of a rack with a drive gear, by means of worm gears, by means of a threaded rod with adjusting nut, etc., to provide a movable actuator which is provided or coupled with control surfaces.

The described side inclination setting is applicable to all kinds of sports shoes that have a relatively stiff upper and lower part, in particular made of hard plastic, i.e. in addition to ski boots also ice skates, single or double-track roller skates or the like.
