Im Innern des Schaftes 12 ist ein, den Innenschuh im Ristbereich überdeckendes Halteelement 18 vorgesehen, und im Fersenbereich ist an der Sohle 14 eine auf den Innenschuh 16 einwirkende, die Ferse von hinten umgreifende Fersenkappe 20 angeordnet. In der Sohle 14 ist eine ortsfeste Spindel 22 drehbar gelagert, deren Längsachse 24 parallel zur Schuhlängsrichtung A verläuft. Mit der Spindel 22 ist die Welle eines Stell motors 26 drehfest verbunden. Der Stellmotor ist mittels eines nicht dargestellten Schaltelementes mit einer ebenfalls nicht dargestellten, im Schuh beispielsweise in der Sohle angeordneten Batterie oder Akkumulator elektrisch verbindbar. Auf der Spindel 22 sitzt eine Mutter 28, die in nicht dargestellter Weise in der Sohle 14 in Schuhlängsrichtung A verschiebbar, aber drehfgest gelagert ist. Ein Zugorgan 30 ist im Innern des Ski schuhs 10 derart geführt, dass es zwei Teilschlaufen 32 und 34 bildet. Die erste Teilschlaufe 32 übergreift das Halteelement 18 in dessen vorderem Endbereich 36, ist beidseits des Vorfusses zur Sohle 14 geführt, wird dort umgelenkt und verläuft in der Sohle 14 ungefähr parallel zur Schuhlängsrichtung A auf beiden Seiten des Stellmo tores 16 und der Mutter 28 vorbei gegen den Fersenbe reich des Skischuhes 10, wird dort wiederum auf in die ser Figur nicht näher dargestellte Weise umgelenkt und verläuft parallel zur Schuhlängsrichtung A zurück zur Mutter 28. Die zweite Teilschlaufe 34 ist im oberen End bereich 38 des Halteelementes 18 um dieses herumgeführt und verläuft beidseits des Fusses zu, an der Fersenkappe 20 seitlich angeordneten Führungselementen 40. Das Zug organ 30 verläuft von jedem Führungselement 40 jeweils um die Fersenkappe 20 herum auf die andere Seite des Skischuhs 10, so dass es sich im Bereich der Fersenkappe 20 kreuzt, und verläuft von dort ungefähr parallel zur Schuhlängsrichtung A in der Sohle 14 zur Mutter 28. Das Zugorgan 30 wird in der Mutter 28, wie dies gestrichelt dargestellt ist, zweimal um 180° umgelenkt, so dass je weils ein im wesentlichen parallel zur Schuhlängsrich tung A zur Mutter 28 verlaufender Abschnitt 42 der er sten Teilschlaufe 32 mit einem jeweiligen entsprechenden Abschnitt 44 der zweiten Teilschlaufe 34 verbunden ist. Das Zugorgan 30 bildet folglich eine einzige geschlos sene Schlaufe, welche derart geführt ist, dass sich zwei Teilschlaufen 32, 34 bilden, die gleichzeitig durch Ver schieben der Mutter 28 in Schuhlängsrichtung A vergrös sert oder verkleinert werden. Um die Grösse der beiden Teilschlaufen 32, 34 an die individuelle Anatomie des Fusses anzupassen, ist das Zugorgan 30 in der Mutter 28 jeweils gleitend geführt. 1 is a ski assumed to be transparent shoe 10 shown in perspective. He shows you Upper 12, one sole 14 and one inside the sheep tes arranged padded inner shoe 16 on. From Shank 12 and the inner shoe 16 are only partially Outlines indicated. Inside the shaft 12 is a Holding element covering the inner shoe in the instep area 18 is provided, and in the heel area there is 14 on the sole one acting on the inner shoe 16, the heel of rear encompassing heel cap 20 arranged. In the Sole 14 is a stationary spindle 22 rotatably mounted, whose longitudinal axis 24 is parallel to the longitudinal direction A of the shoe runs. With the spindle 22 is the shaft of an actuator motor 26 rotatably connected. The servomotor is by means of a switching element, not shown, with a also not shown, in the shoe for example Battery or accumulator arranged in the sole electrically connectable. One sits on the spindle 22 Nut 28, in a manner not shown in the sole 14 slidable in the longitudinal direction of the shoe A, but pivoted is stored. A pulling element 30 is inside the ski shoe 10 is guided in such a way that there are two partial loops 32 and 34 forms. The first partial loop 32 overlaps this Holding element 18 in its front end region 36 is on both sides of the forefoot to the sole 14, is there deflected and runs approximately parallel in the sole 14 to the longitudinal direction of the shoe A on both sides of the Stellmo tores 16 and the nut 28 over against the heel rich of the ski boot 10, is there again on in the This figure deflected and not shown in detail runs parallel to the longitudinal direction of the shoe A back to Nut 28. The second partial loop 34 is in the upper end area 38 of the holding element 18 guided around this and runs towards the heel cap on both sides of the foot 20 laterally arranged guide elements 40. The train organ 30 runs from each guide element 40, respectively around the heel counter 20 to the other side of the Ski boots 10 so that it is in the area of the heel counter 20 crosses, and from there runs approximately parallel to Shoe longitudinal direction A in the sole 14 to the mother 28. The Pulling element 30 is in the nut 28, as shown in dashed lines is shown, deflected twice by 180 °, so that each because a substantially parallel to the longitudinal direction of the shoe device A to the nut 28 extending portion 42 of it Most partial loop 32 with a respective corresponding Section 44 of the second partial loop 34 is connected. The pulling element 30 consequently forms a single closed one sene loop, which is guided in such a way that two Part loops 32, 34 form, which are simultaneously through Ver slide the nut 28 in the longitudinal direction A of the shoe to enlarge it serted or reduced. About the size of the two Partial loops 32, 34 to the individual anatomy of the To adapt to the foot, the pulling element 30 is in the nut 28 each slidingly guided.
In der Fig. 2 ist weder der Schaft 12, noch die Sohle 14, noch der Innenschuh 16 dargestellt; der Fuss des Skifahrers ist gestrichelt angedeutet. Der Einfachheit halber sind nur die im Innern des Schaftes 12 und in der Sohle 14 angeordneten Teile angegeben. Das Halteelement 18 überdeckt sattelförmig den Ristbereich und an einem in der Sohle 14 angeordneten Keil 46 ist die in Schuh längsrichtung A elastisch auslenkbare Fersenkappe 20 be festigt. Das Halteelement 18 wird zwischen dem vorderen und oberen Endbereich 36 bzw. 38 von einem Bügel 48 U-förmig umgriffen. An den, in Schuhlängsrichtung A ge sehen, beidseits des Halteelementes 18 nach unten ge richteten Bügelenden 50 sind Führungen 52 für das Zugor gan 30 angeordnet. In der Mitte des Bügels 48, zwischen den beiden Bügelenden 50, ist eine Stellschraube 54 ge lagert, deren freies Ende sich am Halteelement 18 ab stützt. Die Stellschraube 54 weist einen flachen, gross flächigen Kopf auf, damit die Schraube problemlos von Hand gedreht werden kann. Mit der Stellschraube 54 ist der Abstand quer zur Sohle 14 zwischen dem Bügel 48 und dem Halteelement 18 einstellbar. In FIG. 2 there is neither the upper 12 nor the sole 14, the inner shoe 16 is still shown; the foot of the Skier is indicated by dashed lines. Of simplicity sake are only in the interior of the shaft 12 and in the Sole 14 arranged parts indicated. The holding element 18 covers the instep area in the shape of a saddle and on one The wedge 46 arranged in the sole 14 is the one in the shoe longitudinal direction A elastically deflectable heel cap 20 be solidifies. The holding element 18 is between the front and upper end regions 36 and 38, respectively, of a bracket 48 U-shaped encompassed. To the, in the longitudinal direction of the shoe A ge see, on both sides of the holding element 18 downward ge Directed temple ends 50 are guides 52 for the Zugor gan 30 arranged. In the middle of the bracket 48, between the two temple ends 50, an adjusting screw 54 is ge the free end of which is deposited on the holding element 18 supports. The adjusting screw 54 has a flat, large flat head so that the screw can easily be removed Can be hand rotated. With the adjusting screw 54 is the distance across the sole 14 between the stirrup 48 and the holding element 18 adjustable.
Im oberen Endbereich 38 weist das Halteelement 18 einen, in Richtung gegen das Schienbein gerichteten elastischen Lappen 56 auf, mittels welchem das Halteelement 18 am in der Fig. 2 nicht dargestellten Schaft 12 fixiert ist. Das Zugorgan 30 ist im oberen bzw. vorderen Endbereich 38, 36 in am Halteelement 18 angeformten Führungen gela gert. Aehnliche Führungselemente 40 sind an der, auch im wesentlichen in einer Richtung parallel zur Sohle 14 und quer zur Schuhlängsrichtung A elastisch auslenkbaren Fersenkappe 20 angeformt (vgl. auch Fig. 1). In the upper end area 38, the holding element 18 has a elastic towards the tibia Flap 56, by means of which the holding element 18 on the in the shaft 12, not shown in FIG. 2, is fixed. The pulling element 30 is in the upper or front end area 38, 36 in guides molded onto the holding element 18 gert. Similar guide elements 40 are on the, also in essentially in a direction parallel to the sole 14 and elastically deflectable transversely to the longitudinal direction A of the shoe Heel cap 20 is integrally formed (see also FIG. 1).
Im Keil 46 ist eine Antriebsanordnung 58 vorgesehen, welche die Spindel 22, den Stellmotor 26 sowie die Mutter 28 aufweist. Im Keil 46 sind Ausnehmungen 60 für das Zugorgan 30 vorhanden. A drive arrangement 58 is provided in the wedge 46, which the spindle 22, the servomotor 26 and the Has nut 28. In the wedge 46 there are recesses 60 for the pulling element 30 is present.
Auch beim Skischuh 10 gemäss der Fig. 2 bildet das Zug organ 30 eine erste und eine zweite Teilschlaufe 32 bzw. 34. Die erste Teilschlaufe 32 ist in den oben erwähnten Führungen über das Halteelement 18 im vorderen Endbe reich 36 geführt, verläuft dort zum Keil 36, wird in den Ausnehmungen 60 umgelenkt, ist beidseits des Fusses zu den Führungen 52 im Bügel 48 geführt und verläuft von dort durch weitere Ausnehmungen 60 in analoger Weise, wie das weiter oben beschrieben und in der Fig. 1 ge zeigt ist, zur Mutter 28 der Antriebsanordnung 58. In der Mutter 28 wird das Zugorgan 30 wieder nach hinten umgelenkt, verläuft sich kreuzend in den Führungselemen ten 40 um die Fersenkappe 20 und von dort beidseits des Fusses zum oberen Endbereich 38 des Halteelementes 18. Im Vorfussbereich kann das Zugorgan 30, sich auch im Keil 46 kreuzend, jeweils auf die andere Seite des Fus ses geführt werden und von dort zu den Führungen 52 im Bügel 48 verlaufen. The train also forms in the case of the ski boot 10 according to FIG organ 30 a first and a second partial loop 32 or 34. The first sub-loop 32 is in those mentioned above Guides on the holding element 18 in the front end rich 36 out, runs there to wedge 36, is in the Recesses 60 deflected, is closed on both sides of the foot the guides 52 guided in the bracket 48 and extends from there through further recesses 60 in an analogous manner, as described above and in Fig. 1 ge shows to nut 28 of drive assembly 58. In the nut 28 is the pulling member 30 backwards again deflected, runs crossing in the guide elements th 40 around the heel counter 20 and from there on both sides of the Foot to the upper end area 38 of the holding element 18. In the forefoot area, the pulling element 30, also in the Crossing wedge 46, each on the other side of the foot ses and from there to the guides 52 in the Brackets 48 run.
Das Einsteigen in den Skischuh und das Festziehen des Halteelementes 18 bzw. der Fersenkappe 20 verläuft wie folgt: Um in den Skischuh 10 einsteigen zu können, wird die Mutter 28 durch Drehen der Spindel 20 mittels des Stellmotors 26 in den Bereich der hinteren Endlage ge bracht. Dadurch wird das Zugorgan 30 gelöst, und die beiden Teilschlaufen 32, 34 werden vergrössert. Infolge der Vergrösserung der Teilschlaufen 32 und 34 ist genü gend Platz geschaffen worden, um problemlos in den Ski schuh 10 einsteigen zu können. Nun wird mittels des Stellmotors 26 die Spindel 22 in Gegenrichtung gedreht, so dass die Mutter 28 in Schuhlängsrichtung A gegen die Schuhspitze verschoben wird. Dadurch ziehen sich die beiden Teilschlaufen 32, 34 zusammen, so dass der Innen schuh 16 mittels des Halteelementes 18 und der Fersen kappe 20 satt an den Fuss zur Anlage kommt. Es wird da durch ein schmerzfreier, sicherer Sitz des Fusses im Sckischuh 10 erreicht. Getting into the ski boot and tightening the Holding element 18 or the heel cap 20 runs like follows: In order to be able to get into the ski boot 10, the nut 28 by rotating the spindle 20 by means of the Servomotor 26 ge in the area of the rear end position brings. As a result, the pulling element 30 is released, and the both partial loops 32, 34 are enlarged. As a result the enlargement of the partial loops 32 and 34 is sufficient A lot of space has been created to easily get into the ski to be able to get in shoe 10. Now the Servomotor 26 rotates the spindle 22 in the opposite direction, so that the nut 28 in the shoe longitudinal direction A against the Shoe tip is shifted. This causes the two partial loops 32, 34 together so that the inside shoe 16 by means of the retaining element 18 and the heels cap 20 comes close to the foot of the system. It will be there thanks to a painless, secure fit of the foot in the Reached ski boot 10.
Durch die Führung der zweiten Teilschlaufe 34 um den Fuss und das Halteelement 18 herum zu den Führungsele menten 40 an der Fersenkappe 20, und der anschliessend gekreuzten Führung des Zugorganes 30 wird die elastisch verformbare Fersenkappe 20 seitlich in einer Richtung im wesentlichen parallel zur Sohle 14 und quer zur Schuh längsrichtung A gegen die Ferse gepresst, was einen be sonders guten Halt im Fersenbereich zur Folge hat. By guiding the second partial loop 34 around the Foot and the holding element 18 around to the Führungsele ments 40 on the heel counter 20, and then crossed leadership of the tension member 30 is elastic deformable heel counter 20 laterally in one direction in substantially parallel to the sole 14 and transversely to the shoe longitudinal direction A pressed against the heel, what a be particularly good hold in the heel area.
Mittels der Stellschraube 54 (s. Fig. 2) kann der Ab stand quer zur Sohle 14 zwischen dem Bügel 48 und dem Halteelement 18 vergrössert bzw. verkleinert werden. Falls bei einem niederen Rist die Länge der Spindel 22 nicht ausreicht um das Zugorgan 30 genügend spannen zu können, kann der Abstand zwischen dem Bügel 48 und dem Halteelement 18 vergrössert werden, so dass eine genü gend grosse Zugspannung im Zugorgan 30 ermöglicht wird. Bei einem hohen Rist hingegen liegt der Bügel 48 am Hal teelement 18 an. Die Einstellung des Bügels 48 mit der Stellschraube 54 ist nur ein einziges Mal notwendig, da der Hub der Spindel 22 genügend gross ist, um das Ein steigen in den Schuh bzw. das Festziehen des Halteele mentes 18 und der Fersenkappe 20 bei einer festen Länge des Zugorgans 30 zu ermöglichen. By means of the adjusting screw 54 (see FIG. 2), the Ab stood across the sole 14 between the bracket 48 and the Retaining element 18 can be enlarged or reduced. If with a low instep, the length of the spindle is 22 not sufficient to tension the tension member 30 sufficiently can, the distance between the bracket 48 and the Retaining element 18 are enlarged so that a sufficient Gend large tensile stress in the tension member 30 is made possible. With a high instep, however, the bracket 48 lies on the neck element 18 on. The adjustment of the bracket 48 with the Adjusting screw 54 is only necessary once because the stroke of the spindle 22 is large enough to the one get into the shoe or tighten the retaining element mentes 18 and the heel counter 20 at a fixed length of the pulling member 30 to enable.
In den Figuren 3 und 4 ist die im Keil 46 angeordnete Antriebsanordnung 58 in Draufsicht und in einem Schnitt entlang der Linie IV-IV der Fig. 3 dargestellt. Der Keil 46 weist im Bereich der Antriebsanordnung 58 eine im we sentlichen in Schuhlängsrichtung A verlaufende Ausneh mung 62 auf, in der der Stellmotor 26 sitzt und die Mut ter 28 drehfest, aber in Schuhlängsrichtung A verschieb bar geführt ist. Mit der Welle des Stellmotores 26 ist die Spindel 22 drehfest verbunden, welche an ihrem, dem Stellmotor 26 abgekehrten Endbereich drehbar, aber in Schuhlängsrichtung A nicht verschiebbar am Keil 46 gela gert ist. In diesem Endbereich sitzt auf der Spindel 22 ein Anschlag 64 aus Gummi, der ein hartes Anschlagen der Mutter 28 verhindert. In Figures 3 and 4 is arranged in the wedge 46 Drive assembly 58 in plan view and in section shown along the line IV-IV of FIG. The wedge 46 has in the area of the drive arrangement 58 an in we essential recess running in the longitudinal direction A of the shoe mung 62, in which the servomotor 26 sits and the courage ter 28 rotatably, but shift in the longitudinal direction A of the shoe is managed in cash. With the shaft of the servomotor 26 is the spindle 22 rotatably connected, which at her, the Servomotor 26 turned away from the end area, but in The longitudinal direction of the shoe A cannot be displaced on the wedge 46 device is. The spindle 22 is seated in this end area a stop 64 made of rubber, the hard hitting the Mother 28 prevents.
Die Mutter 28 weist zwei, im wesentlichen kreisegment förmige Nuten 65 auf, in welchen das Zugorgan 30 geführt ist. Im dem Stellmotor 26 entfernten Endbereich der Aus nehmung 62 sind beidseits dieser Ausnehmung um senkrecht zur Sohle 14 verlaufende Achsen Umlenkrollen 66 drehbar gelagert. Weitere Umlenkrollen 70 sind seitlich der Aus nehmung 62 im Bereich des Stellmotores 26 um ebenfalls senkrecht zur Sohle 14 verlaufende Achsen drehbar gela gert. Das Zugorgan 30 der ersten Teilschlaufe 34 ver läuft von der Fersenkappe 20 herkommend mit seinen Ab schnitten 44 ungefähr parallel zur Schuhlängsrichtung A zur Mutter 28, wird dort in den Nuten 65 um 180° umge lenkt und läuft von dort mit den zur ersten Teilschlaufe 32 gehörenden Abschnitten 42 zu den Umlenkrollen 68, ist um diese herumgeführt, verläuft zu den Umlenkrollen 70 und von dort quer zur Schuhlängsrichtung A gegen aussen. Das Zugorgan 30 ist in der Mutter 28 gleitend gelagert, so dass ein Ausgleich der Grösse der beiden Teilschlau fen 32 und 34 möglich ist. Weiter können im Bereich der Ausnehmung 62 Endschalter vorgesehen sein, die den Stellmotor 26 abschalten, sobald die Mutter 28 eine End lage auf der Spindel 22 erreicht hat, damit der Stellmo tor nicht überlastet werden kann. The nut 28 has two, essentially circular segments shaped grooves 65 in which the pulling element 30 is guided is. In the end area remote from the servomotor 26, the off recess 62 are perpendicular to both sides of this recess to the sole 14 extending axes deflection rollers 66 rotatable stored. Further pulleys 70 are on the side of the off take 62 in the area of the servomotor 26 to also Axes running perpendicular to the sole 14 are rotatable gert. The tension member 30 of the first loop part 34 ver runs from the heel cap 20 coming with his Ab cut 44 approximately parallel to the longitudinal direction A of the shoe to the nut 28, is turned there in the grooves 65 by 180 ° steers and runs from there with the to the first partial loop 32 belonging sections 42 to the pulleys 68 is guided around this, runs to the deflection rollers 70 and from there transversely to the longitudinal direction A of the shoe towards the outside. The pulling element 30 is slidably mounted in the nut 28, so that a balance of the size of the two sub-sly fen 32 and 34 is possible. In the area of Recess 62 limit switches may be provided, which the Turn off servomotor 26 as soon as the nut 28 has an end has reached position on the spindle 22 so that the Stellmo tor cannot be overloaded.
In den Figuren 5 und 6 ist in Seitenansicht bzw. entlang einem Schnitt der Linie VI-VI der Fig. 5 der vordere Endbereich 36 eines Halteelementes 18 gezeigt. Dieses Halteelement 18 weist ein Längeneinstellelement 72 auf, mit welchem die Länge des Zugorganes 30 verstellt werden kann. In einer, gegen den, in dieser Figur nicht darge stellten, Schaft 12 vorstehenden Ausbuchtung 74 des Hal teelementes 18 ist ein Schneckenrad 76 um eine Achse pa rallel zur Sohle 14 und quer zur Schuhlängsrichtung A drehbar gelagert. Das Schneckenrad 76 ist mittels eines flexiblen Uebertragungsgliedes 78 mit einem in den Figu ren 5 und 6 nicht dargestellten Drehorgan wirkverbunden, mit welchem das Schneckenrad in beiden Drehrichtungen gedreht werden kann. Das Zugorgan 30 (vgl. Fig. 1) ist im Bereich der ersten Teilschlaufe 32 im Bereich des vorderen Endbereiches 36 des Halteelementes 18 aufge trennt. Ein erstes Zugorganende 80 ist im Bereich der Ausbuchtung 74 am Halteelement 18 fixiert. Das zweite Zugorganende 82 weist ein Band 84 mit einer quer zur Bandlängserstreckung gerichteten Verzahnung 86 auf. Das Band 84 liegt am Haltelement 18 an und ist durch seit liche Oeffnungen 88 in der Ausbuchtung 74 durch diese hindurchgeführt. Die Verzahnung 86 wirkt mit dem Schneckenrad 76 zusammen und hält dieses zugleich in der Ausbuchtung 74 fest. Durch Drehen des Schneckenrades 76 wird das Band 84 in Pfeilrichtung B verschoben, was eine Vergrösserung bzw. eine Verkleinerung der aus den beiden Teilschlaufen 32 und 34 bestehenden Schlaufe zur Folge hat. In Figures 5 and 6 is in side view and along a section along the line VI-VI of FIG. 5, the front End region 36 of a holding element 18 is shown. This Holding element 18 has a length adjustment element 72, with which the length of the pulling element 30 can be adjusted can. In one against which, not shown in this figure posed, shaft 12 protruding bulge 74 of the Hal teelementes 18 is a worm gear 76 about an axis pa parallel to the sole 14 and transversely to the longitudinal direction A of the shoe rotatably mounted. The worm gear 76 is by means of a flexible transmission member 78 with a in the Figu ren 5 and 6 rotating organ, not shown, operatively connected, with which the worm wheel in both directions of rotation can be rotated. The pulling element 30 (see. Fig. 1) is in the area of the first partial loop 32 in the area of the front end region 36 of the holding element 18 up separates. A first Zugorganende 80 is in the area Bulge 74 fixed on holding element 18. The second Zugorganende 82 has a band 84 with a transverse to Toothing 86 directed towards the longitudinal extent of the band. The Band 84 rests against the retaining element 18 and has been through since Liche openings 88 in the bulge 74 through this passed through. The toothing 86 acts with the Worm gear 76 together and holds it at the same time in the Bulge 74 firmly. By turning the worm wheel 76 the band 84 is moved in the direction of arrow B, which is a Enlargement or a reduction in size of the two Partial loops 32 and 34 existing loop result Has.
Die Wirkungsweise des Längeneinstellelementes 72 ist ähnlich jener des Bügels 48 der Fig. 2. Durch einmalige Einstellung der Schlaufengrösse mittels des Längenein stellelementes 72 kann erreicht werden, dass, unabhängig von der Risthöhe, eine geringe Länge der Spindel 22 aus reicht, um ein Einsteigen in den Skischuh 10 zu ermögli chen und trotzdem das Halteelement 18 und die Fersenkap pe 20 satt an den Fuss zu ziehen. The operation of the length adjustment element 72 is similar to that of the bracket 48 of FIG. 2. By one-off Adjustment of the loop size by means of the length adjustment adjusting element 72 can be achieved that, independently from the instep height, a short length of the spindle 22 is enough to get into the ski boot 10 to enable chen and still the retaining element 18 and the heel cap PE 20 to pull hard on the foot.
Es ist durchaus verständlich, dass bei genügender Länge der Spindel 22 auf einen Bügel 48 (s. Fig. 2) oder ein Längeneinstellelement 72 (s. Figuren 5 und 6) verzichtet werden kann. Es ist auch möglich, dass das Zugorgan 30 auf andere Weise geführt ist, wesentlich ist jedoch, dass mittels eines einzigen Zugteils (Mutter 28) die Grösse der Teilschlaufen 32 und 34 vergrössert bzw. ver kleinert werden kann. Das Zugorgan 30 kann in der Mutter 28 fixiert sein, was jedoch bedingt, dass mindestens in einer der beiden Teilschlaufen 32 oder 34 die Länge die ser Teilschlaufen, beispielsweise mittels eines Bügels 48 (s. Fig. 2) oder eines Längeneinstellelementes 72 (s. Figuren 5 und 6) einstellbar ist, um unabhängig von der Anatomie das Halteelement 18 bzw. die Fersenkappe 20 satt an den Fuss zu pressen. It is quite understandable that given sufficient length the spindle 22 on a bracket 48 (see. Fig. 2) or a Length adjustment element 72 (see FIGS. 5 and 6) is omitted can be. It is also possible that the pulling element 30 is managed in a different way, but what is essential is that by means of a single pulling part (nut 28) the Size of the partial loops 32 and 34 enlarged or ver can be reduced. The pulling element 30 can be in the mother 28, which, however, requires that at least in one of the two partial loops 32 or 34 the length ser partial loops, for example by means of a bracket 48 (see Fig. 2) or a length adjustment element 72 (see. Figures 5 and 6) is adjustable to be independent of the Anatomy of the holding element 18 or the heel cap 20 fed up with pressing on the foot.
Anstelle des Stellmotors 26 kann die Spindel 22 bei spielsweise mit einer flexiblen Welle wirkverbunden sein, welche mit einem, von der Schuhaussenseite her be dienbaren Drehrad verbunden ist. Ein solches Drehrad kann irgendwo am Schaft 12 angeordnet sein. Weiter ist es möglich, einen Zugteil, der ähnlich ausgebildet sein kann wie die Mutter 28, mittels eines von der Schuhaus senseite betätigbaren Hebelsystemes zu verschieben. Instead of the servomotor 26, the spindle 22 at for example operatively connected to a flexible shaft be, which with one, be from the shoe house side serving rotary wheel is connected. Such a dial can be located anywhere on the shaft 12. Next is it possible to have a pulling part that is designed similarly can like mother 28, by means of one of the Schuhaus to move the sensor side actuated lever system.
Es ist auch denkbar, einen Zugteil mittels einer pneuma tischen oder hydraulischen Antriebsanordnung zu bewegen. So kann der Zugteil beispielsweise mit dem Kolben eines Kolben-Zylinderaggregates verbunden sein. Eine Pumpen- und Ventilanordnung für die Ansteuerung dieses Kol ben-Zylinderaggregates kann von der Schuhaussenseite be dienbar am Schaft angeordnet sein. It is also conceivable, a pulling part by means of a pneuma table or hydraulic drive assembly to move. For example, the pulling part can be connected to the piston Be connected to the piston-cylinder unit. A pump and valve arrangement for the control of this col ben cylinder unit can be from the outside of the shoe be serviceably arranged on the shaft.
Bei Skischuhen 10 ohne Fersenkappen 20 kann die zweite Teilschlaufe 34 mittels vorzugsweise am Schaft 14 ange ordneten Umlenkorganen gegen den Fersenbereich geführt und von dort zur Antriebsanordnung 58 umgelenkt werden. In the case of ski boots 10 without heel caps 20, the second Partial loop 34 is preferably attached to the shaft 14 by means of arranged deflection organs led against the heel area and deflected from there to the drive arrangement 58.
Die Antriebsanordnung 58 mit dem Stellmotor 26, der Spindel 22, der Mutter 28 und den Umlenkrollen 68, 70 kann auch in einem Einsatz angeordnet sein, der in den Keil 46 oder direkt in die Sohle 14 eingesetzt werden kann. The drive assembly 58 with the servomotor 26, the Spindle 22, the nut 28 and the pulleys 68, 70 can also be arranged in an insert that is in the Wedge 46 or can be used directly in the sole 14 can.
