Abstract

The upper shaft part (16) can be pivoted on the lower shaft part (12) about the axis (20) from a standing position running approximately at right angles to the sole (14) into a forwardly inclined rest position which corresponds to the moving position. This pivoting movement of the upper shaft part (16) with the ski boot closed is transmitted by the actuation lever (82) to transmission members (86) which are displaceable in the longitudinal direction of the boot. The movement of the transmission members (86) towards the heel element (98) is converted into a forward sliding of the tensioning member (90). In this connection, the active part loops (106, 108) of the tensioning element (102), which is guided around the tensioning member (90), are shortened. With the upper shaft part (16) in the rest position, the foot is consequently secured by the holding element (96) and the heel cap (100). With the upper shaft part (16) pivoted back into the standing position, the foot is free inside the ski boot. <IMAGE>

Description

Die vorliegende Erfindung betrifft einen Skischuh gemäss dem Oberbegriff des Anspruchs 1.The present invention relates to a ski boot according to the preamble of claim 1.

Ein Skischuh dieser Art ist aus der EP-A-0 111 822 bekannt. An einem den Fuss zu umfassen bestimmten unteren Schaftteil sind um eine gemeinsame Achse ein vorderer und ein hinterer Schaftteil zwischen einer Stehlage und einer nach vorne geneigten Ruhelage hin und her schwenkbar gelagert. Diese beiden einen Schaftoberteil bildenden Schaftteile sind zum Umfassen des unteren Teils des Unterschenkels bestimmt. Um den Schaftoberteil in Ruhelage zu arretieren ist eine zwischen dem unteren und vorderen Schaftteil wirkende, manuell betätigbare Arretiervorrichtung vorgesehen, die in Arretierstellung über einen Druckbolzen eine im Innern des Skischuhs vorhandene Ristplatte belastet und den oberen Schaftteil in Ruhelage festlegt und die in Freigabestellung sowohl die Ristplatte als auch den oberen Schaftteil freigibt.A ski boot of this type is known from EP-A-0 111 822. On a lower shaft part to be encompassed by the foot, a front and a rear shaft part are pivotably mounted to and fro about a common axis between a standing position and a forward rest position. These two shaft parts forming an upper part of the shaft are intended to enclose the lower part of the lower leg. In order to lock the upper part of the shaft in the rest position, a manually operable locking device is provided which acts between the lower and front part of the shaft, which, in the locked position, loads an instep plate inside the ski boot and fixes the upper part of the shaft in the rest position and which fixes both the instep plate in the release position as well as the upper part of the shaft.

Weiter ist in der EP-A-0 226 857 ein Skischuh offenbart, über dessen Ristplatte ein kabelartiges Spannelement geführt ist, das einerends ortsfest am den Fuss zu umfassen bestimmten unteren Schaftteil und andernends an einer auf der Oberseite des unteren Schaftteils in Schuhlängsrichtung verschiebbar gelagerten Zahnriemen befestigt ist. Mit dem Zahnriemen wirken ein am unteren Schaftteil gelagerter Rasthebel und ein am vorderen Schaftteil gelagerter Spannhebel zusammen, die beide gegen den Zahnriemen vorgespannt sind. Der zum Umfassen des unteren Schienbeinbereichs bestimmte vordere Schaftteil und ein zum Umfassen des Fersen- und unteren Wadenbeinbereichs bestimmter hinterer Schaftteil sind am unteren Schaftteil schwenkbar gelagert, wobei diese Schaftteile bei geschlossenem Skischuh im Bereich der Ruhelage oszillieren können. Beim Vorwärtsoszillieren nimmt der Spannhebel jeweils den Zahnriemen mit und beim Rückwärtsoszillieren ist dieser mittels des Rasthebels gehalten. In dieser Art wird durch mehrmaliges Oszillieren das Spannelement gespannt. Um beim Oszillieren während dem Fahren ein weiteres Spannen zu verhindern, ist der Spannhebel in einer aus dem Bereich des Zahnriemens zurückverschwenkten Ruhelage arretierbar. Um das Spannelement zu lösen, kann der Rasthebel ausser Eingriff mit dem Zahnriemen verschwenkt werden.Furthermore, EP-A-0 226 857 discloses a ski boot, over the instep plate of which a cable-like tensioning element is guided, which has a fixed lower shaft part to be fixed at one end on the foot and the other on a toothed belt that is mounted on the top of the lower shaft part in the longitudinal direction of the shoe is attached. A toothed lever mounted on the lower shaft part and a tensioning lever mounted on the front shaft part interact with the toothed belt, both of which are pretensioned against the toothed belt. The front shaft part intended to encompass the lower shin region and a rear shaft part intended to encompass the heel and lower fibula region are pivotably mounted on the lower shaft part, these shaft parts can oscillate in the rest position when the ski boot is closed. When oscillating forwards the tensioning lever takes the toothed belt with it and when oscillating backwards it is held by means of the locking lever. In this way, the tensioning element is tensioned by repeated oscillation. In order to prevent further tensioning when oscillating while driving, the tensioning lever can be locked in a rest position pivoted back from the area of the toothed belt. To release the tensioning element, the locking lever can be pivoted out of engagement with the toothed belt.

Ein weiterer Skischuh ist aus der US-PS 4,160,332 bekannt. Dieser weist einen den Fuss umschliessenden unteren Schaftteil auf, an dem ein den unteren Schienbeinbereich umschliessender vorderer Schaftteil einstückig angeformt ist. Ein im Fersen- und unteren Wadenbeinbereich vorgesehener hinterer Schaftteil ist im Bereich des Fussgelenkes am unteren Schaftteil um eine parallel zur Sohle und rechtwinklig zur Schuhlängsrichtung verlaufende Achse schwenkbar angelenkt. Im Innern des Skischuhs ist ein Fusshalteelement mit einem bandförmigen über den Rist verlaufenden Spannelement vorgesehen. Dieses ist mit einem unterhalb der Anlenkung des hinteren Schaftteils am unteren Schaftteil hindurchgeführten Spannkabel verbunden, das wahlweise an einem von mehreren übereinander angeordneten Zähnen am hinteren Schaftteil eingehängt ist. Zum Oeffnen des Skischuhs wird der hintere Schaftteil nach hinten verschwenkt, wodurch das Spannkabel und somit das Fusshalteelement gelöst wird. Beim Schliessen des Skischuhs wird der hintere Schaftteil in Richtung gegen vorne verschwenkt, wobei durch diese Schwenkbewegung das Spannkabel gespannt und somit das Fusshalteelement in Richtung gegen die Ferse gezogen wird. Bei geschlossenem Skischuh ist somit das Fusshalteelement immer gespannt und ein Lösen des Fusshalteelementes ist nur durch Oeffnen des Skischuhs moglich. Ein offener Skischuh ist allerdings zum Fahren mit einem Lift bzw. beim Gehen äusserst unerwünscht. Um ein Erholen des Fusses bei geschlossenem Skischuh zu ermöglichen, muss der Skischuh geöffnet und das Spannkabel aus dem betreffenden Zahn gelöst und in einen weiter unten angeordneten Zahn eingehängt werden. Anchliessend ist der Skischuh durch Nachvorneverschwenken des hinteren Schaftteils wieder zu schliessen, wodurch nun das Fusshalteelement weniger gespannt wird. In analoger Weise ist für die nächste Abfahrt dann durch erneutes Einhängen des Spannkabels in einen weiter oben angeordneten Zahn das Fusshalteelement wieder stärker zu spannen. Dieses Vorgehen ist äusserst aufwendig und kompliziert.Another ski boot is known from US Pat. No. 4,160,332. This has a lower shaft part enclosing the foot, on which a front shaft part enclosing the lower shin area is integrally formed. A rear shaft part provided in the heel and lower fibula region is pivotably articulated in the area of the ankle on the lower shaft part about an axis running parallel to the sole and perpendicular to the longitudinal direction of the shoe. A foot holding element with a band-shaped tensioning element running over the instep is provided in the interior of the ski boot. This is connected to a tensioning cable which is guided underneath the articulation of the rear shaft part on the lower shaft part and is optionally hooked onto one of several teeth arranged one above the other on the rear shaft part. To open the ski boot, the rear part of the shaft is pivoted backwards, which releases the tensioning cable and thus the foot support element. When the ski boot is closed, the rear part of the shaft is pivoted in the direction towards the front, the tensioning cable being tensioned by this pivoting movement and thus the foot holding element being pulled in the direction of the heel. When the ski boot is closed, the foot holding element is thus always tensioned and the foot holding element can only be released by opening the ski boot. An open ski boot is, however, for Driving with a lift or when walking is extremely undesirable. In order to allow the foot to recover when the ski boot is closed, the ski boot must be opened and the tensioning cable released from the tooth concerned and hooked into a tooth located further down. The ski boot can then be closed again by swiveling the rear part of the shaft forward, which means that the foot support element is less tensioned. In an analogous manner, the foot holding element can then be tightened again for the next descent by hanging the tensioning cable again in a tooth located further up. This procedure is extremely complex and complicated.

Es ist deshalb eine Aufgabe der vorliegenden Erfindung einen gattungsgemässen Skischuh zu schaffen, der bei geschlossenem Skischuh ein angenehmes Gehen ermöglicht.It is therefore an object of the present invention to provide a generic ski boot which enables comfortable walking when the ski boot is closed.

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teiles des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Erfindungsgemäss ist der vordere und hintere Schaftteil bei geschlossenem Skischuh gemeinsam aus einer ungefähr senkrecht zur Sohle verlaufenden Stehlage in eine nach vorne geneigte Ruhelage verschenkbar. Bei der gemeinsamen Schwenkbewegung des vorderen und hinteren Schaftteils in die Ruhelage wird das Fusshalteelement gespannt. Die Ruhelage entspricht dabei der üblichen Stellung des vorderen und hinteren Schaftteils bei der Abfahrt. Zum Oeffnen des Skischuhs wird somit der vordere und hintere Schaftteil in die Stehlage zurückverschwenkt und nach dem Einsteigen und verschliessen des Skischuhs werden diese beiden Schaftteile für die Abfahrt gemeinsam in die Ruhelage nach vorn verschwenkt, was gleichzeitig zu einem Anspannen des Fusshalteelementes führt. Die vorliegende Erfindung erlaubt somit ein aufrechtes Stehen ohne dass der Unterschenkel in einer nach vorn geneigten Lage gehalten ist. Dabei ist auch das Fusshalteelement gelöst, was eine Erholung des Fusses bei geschlossenem Skischuh ermöglicht. Da der vordere und hintere Schaftteil bei geschlossenem Skischuh zwischen der Stehlage und der Ruhelage hin- und herschwenkbar sind, ist mit dem erfindungsgemässen Skischuh ausserdem ein problemloses Gehen möglich. Beim jeweiligen Nachvornebeugen des Unterschenkels wird die Fusshalteinrichtung entsprechend der Vorlage des Unterschenkels gespannt und beim Zurückverschwenken in die Stehlage wieder gelockert.According to the invention, when the ski boot is closed, the front and rear shaft parts can be given away together from a standing position approximately perpendicular to the sole into a rest position inclined towards the front. When the front and rear shaft parts swivel together into the rest position, the foot holding element is tensioned. The rest position corresponds to the usual position of the front and rear shaft parts on the descent. To open the ski boot, the front and rear shaft parts are thus pivoted back into the standing position and after getting in and closing the ski shoe, these two shaft parts become pivoted forward for the descent into the rest position, which at the same time leads to a tensioning of the foot holding element. The present invention thus allows an upright standing without the lower leg is held in a forward inclined position. The foot support element is also released, which enables the foot to relax when the ski boot is closed. Since the front and rear shaft parts can be swiveled back and forth between the standing position and the rest position when the ski boot is closed, problem-free walking is also possible with the ski boot according to the invention. Each time the lower leg is bent forward, the foot holding device is tensioned in accordance with the template of the lower leg and loosened again when swiveling back into the standing position.

Der Schaft 10 aus Kunststoff des in den Figuren 1 bis 3 dargestellten Skischuhs weist einen den Fuss umfassenden unteren Schaftteil 12 mit einer daran angeformten Sohle 14 auf. Am unteren Schaftteil 12 ist im Bereich des Fussgelenkes ein oberer Schaftteil 16 mittels schematisch angedeuteten Gelenken 18, von welchen in den Figuren nur eines sichtbar ist, um eine im wesentlichen parallel zur Sohle 14 und rechtwinklig zur Schuhlängsrichtung A verlaufende Achse 20 schwenkbar angelenkt. Der obere Schaftteil 16 weist einen den unteren Schienbeinbereich umfassenden vorderen Schaftteil 22 und einen den Fersen- und unteren Wadenbeinbereich umfassenden hinteren Schaftteil 24 auf. Diese beiden Schaftteile 22 und 24 sind an den Gelenken 18 gelagert und mittels eines bekannten, schematisch angedeuteten Verschlusses 26 gegeneinander spannbar um den unteren Beinbereich des Fahrers zu umschliessen. Zum Oeffnen des Skischuhs ist der Verschluss 26 zu öffnen und der hintere Schaftteil 24 um die Achse 20 gegen hinten zu schwenken.The shaft 10 made of plastic of the ski boot shown in FIGS. 1 to 3 has a lower shaft part 12 encompassing the foot with a sole 14 molded onto it. On the lower shaft part 12, in the area of the ankle, an upper shaft part 16 is articulated by means of schematically indicated joints 18, only one of which is visible in the figures, about an axis 20 which runs essentially parallel to the sole 14 and perpendicular to the longitudinal direction A of the shoe. The upper shaft part 16 has a front shaft part 22 comprising the lower shin region and a rear shaft part 24 comprising the heel and lower fibula regions. These two shaft parts 22 and 24 are mounted on the joints 18 and can be tensioned against one another by means of a known, schematically indicated closure 26 in order to enclose the lower leg region of the driver. To open the ski boot, the closure 26 has to be opened and the rear shaft part 24 swiveled about the axis 20 towards the rear.

In den Figuren 1 und 3 ist der obere Schaftteil 16 in einer bezüglich einer Senkrechten 28 zur Sohle 14 in Pfeilrichtung B um die Achse 20 in Richtung gegen vorn geneigte Ruhelage verschwenkt dargestellt. Die Ruhelage entspricht der üblichen Stellung beim Fahren. In der Figur 2 ist diese Ruhelage gestrichelt angedeutet und mit 16 bezeichnet. In ausgezogenen Linien ist der obere Schaftteil in seiner mit 16' angegebenen Stehlage dargestellt, in welcher er aus der Ruhelage 16 entgegen Pfeilrichtung B in Richtung gegen die Senkrechte 28 verschwenkt ist.In FIGS. 1 and 3, the upper shaft part 16 is shown pivoted in a rest position inclined with respect to a perpendicular 28 to the sole 14 in the direction of arrow B about the axis 20 in the direction toward the front. The rest position corresponds to the usual position when driving. This rest position is indicated by dashed lines in FIG. 2 and is designated by 16. In solid lines, the upper shaft part is shown in its standing position indicated by 16 ', in which it is pivoted from the rest position 16 against the direction of arrow B in the direction against the vertical 28.

Im Ristbereich ist eine Haltevorrichtung 30 mit einer Rasteinrichtung 32 zum lösbaren Festhalten des oberen Schaftteils 16 in seiner nach vorn geneigten Ruhelage vorgesehen. Die Rasteinrichtung 32 weist einen am unteren Schaftteil 12 etwa in Schuhlängsrichtung A verschiebbar gelagerten Schlitten 34 auf. Der Schlitten 34 ist im unteren Schaftteil 12, beispielsweise mittels einer Schwalbenschwanz- oder Keil- Nutführung, verschiebbar gelagert. Am in Schuhlängsrichtung A gesehen hinteren Endbereich weist der Schlitten 34 eine gegen oben vorstehende Nase 36 mit einer Anschlagfläche 38 auf. Am vorderen Schaftteil 22 ist eine in den Bereich des Schlittens 34 vorstehende Rastzunge 40 angeformt. Diese weist einen im Querschnitt rechteckigen Durchlass 42 auf, dessen in Schuhlängsrichtung A gesehen vordere Begrenzung eine Gegenanschlagfläche 44 bildet. Im Mittelbereich des Schlittens 34 ist an diesem ein gabelförmiger, doppelarmiger Hebel 46 um eine parallel zur Sohle 14 und rechtwinklig zur Schuhlängsrichtung A verlaufende Achse 46' schwenkbar gelagert. Die seitlich des Schlittens 34 verlaufenden und von der Achse 46' gegen hinten gerichteten Hebelarme 48 untergreifen mit ihren freien Endbereichen die Rastzunge 40. Die bezüglich der Achse 46' in Schuhlängsrichtung A gegen vorne vorstehenden Hebelarme 50 sind mittels eines plattenförmigen, oberhalb des Schlittens 34 und ungefähr parallel zu diesem angeordneten Verbindungsteils 52 miteinander verbunden. Zwischen dem Verbindungsteil 52 und dem Schlitten 34 ist eine Druckfeder 54 vorgesehen, welche den doppelarmigen Hebel 46 entgegen dem Uhrzeigersinn in der in den Figuren 1 und 2 gezeigten Lage hält. In der Figur 1 liegt die Gegenanschlagfläche 44 der Rastzunge 40 an der Anschlagfläche 38 der Nase 36 an, wodurch der obere Schaftteil 16 in seiner in Richtung gegen vorn geneigten Ruhelage gehalten ist. In der Figur 2 sind die Anschlag- und Gegenanschlagflächen 38, 44 ausser Ueberlappung gebracht und die Rastzunge 40 liegt mit ihrem am vorderen Endbereich vorgesehenen den Durchlass 42 gegen vorn begrenzenden Verbindungssteg 56 auf einer Gleitfläche 36' der Nase 36 auf.In the instep area, a holding device 30 is provided with a latching device 32 for releasably holding the upper shaft part 16 in its rest position, which is inclined forward. The latching device 32 has a slide 34 which is mounted on the lower shaft part 12 and is displaceable approximately in the longitudinal direction A of the shoe. The carriage 34 is slidably mounted in the lower shaft part 12, for example by means of a dovetail or keyway guide. At the rear end region seen in the longitudinal direction A of the shoe, the slide 34 has a nose 36 protruding toward the top with a stop surface 38. A latching tongue 40 protruding into the area of the slide 34 is formed on the front shaft part 22. This has a passage 42 with a rectangular cross section, the front boundary of which, viewed in the longitudinal direction A of the shoe, forms a counter abutment surface 44. In the middle region of the slide 34, a fork-shaped, double-armed lever 46 is pivotally mounted thereon about an axis 46 ′ running parallel to the sole 14 and at right angles to the longitudinal direction A of the shoe. The lever arms 48, which run to the side of the slide 34 and are directed towards the rear from the axis 46 ', engage under the latching tongue 40 with their free end regions. The lever arms 50 projecting towards the front with respect to the axis 46' in the longitudinal direction A of the shoe are by means of a plate-shaped, above the slide 34 and connected to one another approximately parallel to this arranged connecting part 52. Between the connecting part 52 and the carriage 34, a compression spring 54 is provided, which holds the double-armed lever 46 counterclockwise in the position shown in FIGS. 1 and 2. In FIG. 1, the counter stop surface 44 of the latching tongue 40 lies on the stop surface 38 the nose 36, whereby the upper shaft part 16 is held in its rest position inclined towards the front. In FIG. 2, the abutment and counter abutment surfaces 38, 44 are brought out of overlap and the latching tongue 40 rests on a sliding surface 36 ′ of the nose 36 with its connecting web 56, which is provided at the front end region and limits the passage 42 towards the front.

Der Schlitten 34 ist mittels eines Spindeltriebes 58 in seiner Lage bezüglich der Schuhlängsrichtung A einstellbar festgehalten. Im Zehenbereich weist der untere Schaftteil 12 zwei gegen oben vorstehende Lagernocken 60, 60' auf, an welchen eine Spindel 62 des Spindeltriebs 58 frei drehbar aber in Schuhlängsrichtung A gesehen ortsfest gelagert ist. Die Drehachse der Spindel 62 verläuft in der Schuhlängsmittelebene und im wesentlichen parallel zur Oberfläche des unteren Schaftteils 12. Im vom hinteren Lagernocken 60 in Richtung gegen hinten abstehenden Bereich weist die Spindel 62 ein in den Figuren nicht dargestelltes Gewinde auf, in welchem der Schlitten 34 als Laufmutter läuft. Im Bereich zwischen den beiden Lagernocken 60, 60' ist die Spindel 62 als Betätigungswalze 64 verdickt ausgebildet.The position of the slide 34 is adjustable by means of a spindle drive 58 in relation to the longitudinal direction A. In the toe region, the lower shaft part 12 has two bearing cams 60, 60 ′ protruding towards the top, on which a spindle 62 of the spindle drive 58 is freely rotatable but is fixed in position in the longitudinal direction A of the shoe. The axis of rotation of the spindle 62 extends in the longitudinal plane of the shoe and essentially parallel to the surface of the lower shaft part 12. In the region protruding from the rear bearing cam 60 in the direction towards the rear, the spindle 62 has a thread, not shown in the figures, in which the slide 34 as Running nut runs. In the area between the two bearing cams 60, 60 ', the spindle 62 is designed to be thickened as an actuating roller 64.

Seitlich unterhalb des Rastzunge 40 sind zwei Druckfederelemente 66 vorgesehen, die sich einerends am unteren und andernends am vorderen Schaftteil 12, 22 abstützen (Fig. 1 und 2). Wie in der Figur 3 gezeigt, ist die Haltevorrichtung 30 mit der Rasteinrichtung 32 gemäss den Figuren 1 und 2 von einem schalenförmigen Deckelelement 68 überdeckt, um das Eindringen von Schnee und Eis zu verhindern. Das Deckelelement 68 weist auf seiner Oberseite Ausnehmungen für den Verbindungsteil 52 und die Betätigungswalze 64 auf. Das Deckelelement 68 erstreckt sich vom Zehenbereich bis in den Bereich der Nase 36 und Rastzunge 40. Zwischen dem Deckelelement 68 und dem vorderen Schaftteil 22 ist ein elastischer Balg 74 vorgesehen, welcher die Druckfederelemente 66 und die Rastzunge 40 überdeckt und eine Relativverschiebung zwischen dem Deckelelement 68 und dem vorderen Schaftteil 22 zulässt.Two compression spring elements 66 are provided laterally below the latching tongue 40, which are supported at one end on the lower and on the other end on the front shaft part 12, 22 (FIGS. 1 and 2). As shown in FIG. 3, the holding device 30 with the latching device 32 according to FIGS. 1 and 2 is covered by a shell-shaped cover element 68 in order to prevent the ingress of snow and ice. The cover element 68 has recesses on its upper side for the connecting part 52 and the actuating roller 64. The cover element 68 extends from the toe region to the area of the nose 36 and latching tongue 40. Between the cover element 68 and the front shaft part 22, an elastic bellows 74 is provided, which covers the compression spring elements 66 and the latching tongue 40 and a relative displacement between the cover element 68 and the front shaft part 22.

Zum Fahren ist der obere Schaftteil 16 in die in den Figuren 1 und 3 gezeigte Ruhelage in Pfeilrichtung B nach vorn geschwenkt, in welcher die Gegenanschlagfläche 44 an der Anschlagfläche 38 anliegt. Die Ruhelage 16 entspricht somit der gewöhnlichen Fahrstellung. Ein bezüglich der Ruhelage 16 in Pfeilrichtung B weiteres Nachvorneverschwenken des oberen Schaftteils 16 durch Nachvornebeugen des Unterschenkels entgegen der Kraft der Druckfederelemente 66 wird von der Rasteinrichtung 32 ermöglicht. Dabei heben sich die Anschlag- und Gegenanschlagflächen 38, 44 voneinander ab und der Verbindungssteg 56 gleitet infolge der Vorspannung der Rastzunge 40 in Richtung gegen die Sohle 14 auf dem Schlitten 34 im Bereich zwischen der Nase 36 und der Achse 46'. Ein Zurückverschwenken entgegen Pfeilrichtung B über die Ruhelage 16 hinaus wird allerdings durch die Nase 36 und den Verbindungssteg 56 verhindert.For driving, the upper shaft part 16 is pivoted forward in the rest position shown in FIGS. 1 and 3 in the direction of arrow B, in which the counter abutment surface 44 bears against the abutment surface 38. The rest position 16 thus corresponds to the normal driving position. A further forward pivoting of the upper shaft part 16 in the direction of arrow B with respect to the rest position 16 by forward bending of the lower leg against the force of the compression spring elements 66 is made possible by the latching device 32. The abutment and counter abutment surfaces 38, 44 stand out from one another and the connecting web 56 slides due to the pretensioning of the latching tongue 40 in the direction against the sole 14 on the carriage 34 in the region between the nose 36 and the axis 46 '. A pivoting back against the direction of arrow B beyond the rest position 16 is prevented by the nose 36 and the connecting web 56.

Zum Aussteigen aus dem Skischuh, zum aufrechten Stehen, Fahren mit dem Lift oder Gehen wird nun mittels des Skistocks auf den Verbindungsteil 52 gedrückt. Dabei verschwenkt sich der doppelarmige Hebel 46 entgegen der Kraft der Druckfeder 54 im Uhrzeigersinn und die Hebelarme 48 heben den vorderen Bereich der Rastzunge 40 entgegen ihrer Vorspannung in Eingriffsrichtung über die Nase 36 an. Dabei kommen die Anschlag- und Gegenanschlagflächen 38, 44 ausser Eingriff und der obere Schaftteil 16 ist nun aus der Ruhelage entgegen Pfeilrichtung B verschwenkbar. Beim Abheben des Skistocks ab dem Verbindungsteil 52 schwenkt der doppelarmige Hebel 46 im Gegenuhrzeigersinn in die in den Figuren gezeigte Lage zurück, wodurch nun der Verbindungssteg 56 auf die Nase 36 zu liegen kommt (vergl. Fig. 2). Bei gelöster Rasteinrichtung 32 ist somit ein aufrechtes Stehen und bequemes Ein- und Aussteigen in den Skischuh möglich. Ueberdies ist beim Gehen ein Schwenken des oberen Schaftteils 16 in und entgegen Pfeilrichtung B zwischen der Stehlage 16' und der Ruhelage 16 möglich, wobei der Verbindungssteg 56 auf der Gleitfläche 36' gleitet. Ein bequemes Gehen mit geschlossenem Skischuh ist somit möglich. Zum Fahren wird der obere Schaftteil 16 durch Nachvornebeugen des Unterschenkels in Pfeilrichtung B in die Ruhelage 16 verschwenkt. Dabei läuft der Verbindungssteg 56 ab der Rastnase 36 ab, wodurch nun infolge der Vorspannung der Rastzunge 40 in Eingriffsrichtung die Gegenanschlagfläche 44 mit der Anschlagfläche 38 in Eingriff kommt (Fig. 1). Der obere Schaftteil 16 wird nun zum Fahren in der Ruhelage gehalten.To get out of the ski boot, to stand upright, drive with the lift or walk, the connecting piece 52 is now pressed by means of the ski pole. The double-armed lever 46 pivots counterclockwise against the force of the compression spring 54 and the lever arms 48 raise the front region of the latching tongue 40 against it Preload in the direction of engagement via the nose 36. The stop and counter stop surfaces 38, 44 come out of engagement and the upper shaft part 16 can now be pivoted out of the rest position in the opposite direction of the arrow B. When the ski pole is lifted off the connecting part 52, the double-armed lever 46 pivots counterclockwise back into the position shown in the figures, as a result of which the connecting web 56 now lies on the nose 36 (cf. FIG. 2). When the locking device 32 is released, it is thus possible to stand upright and comfortably get in and out of the ski boot. Moreover, when walking, the upper shaft part 16 can be pivoted in and against the direction of arrow B between the standing position 16 'and the rest position 16, the connecting web 56 sliding on the sliding surface 36'. It is therefore possible to walk comfortably with the ski boot closed. For driving, the upper shaft part 16 is pivoted into the rest position 16 by forward bending of the lower leg in the direction of arrow B. The connecting web 56 runs from the detent 36, as a result of which the counter-stop surface 44 comes into engagement with the stop surface 38 as a result of the pretensioning of the latching tongue 40 (FIG. 1). The upper shaft part 16 is now held in the rest position for driving.

Durch Verdrehen der Spindel 62 ist der Schlitten 34 etwa in Schuhlängsrichtung (A), d.h. in Richtung der Relativbewegung zwischen der Rastzunge 40 und dem Schlitten 34 beim Verschwenken des oberen Schaftteils 16, in seiner Lage veränderbar. Dadurch kann die für die Abfahrt gewünschte Ruhelage eingestellt werden.By turning the spindle 62, the slide 34 is approximately in the longitudinal direction of the shoe (A), i.e. its position can be changed in the direction of the relative movement between the latching tongue 40 and the slide 34 when the upper shaft part 16 is pivoted. This allows the rest position desired for the descent to be set.

In der Figur 4 ist der in den Figuren 1 bis 3 gezeigte Skischuh vereinfacht und als durchsichtig angenommen dargestellt. Der besseren Uebersichtlichkeit halber ist die Haltevorrichtung 30 mit der Rasteinrichtung 32 in dieser Figur 4 nicht gezeigt. Am unteren Schaftteil 12 mit der Sohle 14 ist im Bereich des Fussgelenkes der obere Schaftteil 16 mit dem vorderen Schaftteil 22 und dem hinteren Schaftteil 24 um die Achse 20 schwenkbar angelenkt. Im Innern des Skischuhs ist eine Spanneinrichtung 76 für eine Fusshalteeinrichtung 78 vorgesehen.FIG. 4 shows that shown in FIGS. 1 to 3 Ski boot simplified and shown as accepted as transparent. For the sake of clarity, the holding device 30 with the latching device 32 is not shown in this FIG. 4. On the lower shaft part 12 with the sole 14, the upper shaft part 16 with the front shaft part 22 and the rear shaft part 24 is pivotably articulated about the axis 20 in the region of the ankle joint. A tensioning device 76 for a foot holding device 78 is provided in the interior of the ski boot.

Die Gelenke 18 weisen je einen im unteren Schaftteil 12 frei drehbar gelagerten Gelenkzapfen 80 auf, welcher einerseits mit dem vorderen Schaftteil 22 und andererseits mit einem im Innern des Skischuhs vorgesehenen, in Richtung gegen die Sohle 14 vom Gelenkzapfen 80 abstehenden, einarmigen Betätigungshebel 82 drehfest verbunden ist. An den beiden Gelenkzapfen 80 ist auch der hintere Schaftteil 24 schwenkbar gelagert. An ihren freien Enden sind die beiden Betätigungshebel 82 mit einem zylinderförmigen Schaft 84 miteinander verbunden, dessen Längsachse parallel zur Achse 20 verläuft.The joints 18 each have a pivot pin 80 which is freely rotatably mounted in the lower shaft part 12 and which is connected on the one hand to the front shaft part 22 and, on the other hand, to a one-armed actuating lever 82 provided in the interior of the ski boot and projecting in the direction toward the sole 14 from the pivot pin 80 is. The rear shaft part 24 is also pivotably mounted on the two pivot pins 80. At their free ends, the two actuating levers 82 are connected to one another by a cylindrical shaft 84, the longitudinal axis of which extends parallel to the axis 20.

Im Bereich der Sohle 14 sind zwei in Richtung des Schaftes 84 voneinander beabstandete profilförmige Uebertragungsorgane 86 in Schuhlängsrichtung A verschiebbar gelagert. Die beiden Uebertragungsorgane 86 weisen, in Schuhlängsrichtung A gesehen, in ihrem Mittelbereich je eine in Richtung gegen oben offene, rechtwinklig zur Schuhlängsrichtung A verlaufende Nut 88 auf. Der Schaft 84 verläuft durch die Nut 88, wobei die Breite der Nut 88 nur geringfügig grösser ist als der Durchmesser des Schaftes 84.In the area of the sole 14, two profile-shaped transmission members 86 spaced apart from one another in the direction of the shaft 84 are mounted so as to be displaceable in the longitudinal direction A of the shoe. The two transmission elements 86, as seen in the longitudinal direction of the shoe A, each have a groove 88 in their central region which is open in the direction towards the top and runs at right angles to the longitudinal direction of the shoe A. The shaft 84 runs through the groove 88, the width of the groove 88 being only slightly larger than the diameter of the shaft 84.

Zwischen den beiden Uebertragungsorganen 86 ist ein schlittenförmiges Spannorgan 90 angeordnet, das ebenfalls in Schuhlängsrichtung A gleitend geführt ist. Die beiden Uebertragungsorgane 86 und das Spannorgan 90 weisen auf den einander zugewandten Seiten in Schuhlängsrichtung A verlaufende zahnstangenförmige Verzahnungen 92 auf, die mit zwei zwischen dem Spannorgan 90 und den Uebertragungsorganen 86 vorgesehenen Zahnrädern 94 kämmen. Die Zahnräder 94 sind in nicht dargestellten Zapfen um rechtwinklig zur Sohle 14 verlaufende Drehachsen 94' drehbar gelagert (vergl. Fig. 5). Die Zapfen können an der Sohle 14, an einer nicht dargestellten aber allgemein bekannten Innensohle oder an einem Lagerungsteil für die Spanneinrichtung 76 angeordnet sein. Die Verzahnungen 92 und Zahnräder 94 bewirken eine Umkehrung der Bewegungsrichtung des Spannorganes 90 bezüglich den Uebertragungsorganen 86. Beim Verschieben der Uebertragungsorgane 86 in Schuhlängsrichtung A gegen hinten wird das Spannorgan 90 in Schuhlängsrichtung A gegen vorne bewegt und umgekehrt.A sled-shaped tensioning element 90 is arranged between the two transmission elements 86 and is likewise guided in a sliding manner in the longitudinal direction A. The two transmission elements 86 and the tensioning element 90 have toothed rack-shaped toothings 92 which run in the longitudinal direction A of the shoe and which mesh with two toothed wheels 94 provided between the tensioning element 90 and the transmission elements 86. The gear wheels 94 are rotatably mounted in journals (not shown) about axes of rotation 94 ′ running at right angles to the sole 14 (see FIG. 5). The pins can be arranged on the sole 14, on an insole (not shown but generally known) or on a bearing part for the tensioning device 76. The toothing 92 and toothed wheels 94 cause a reversal of the direction of movement of the tensioning element 90 with respect to the transmission elements 86. When the transmission elements 86 are moved in the longitudinal direction A of the shoe, the tensioning element 90 is moved forwardly in the longitudinal direction A of the shoe and vice versa.

Die Fusshalteeinrichtung 78 ist gleich ausgebildet, wie dies in der EP-A 0 321 714 ausführlich beschrieben ist. Diese Fusshalteeinrichtung 78 weist ein zwischen dem Schaft 10 und einem allgemein bekannten, gepolsterten, in den Figuren nicht gezeigten Innenschuh angeordnetes, gestrichelt angedeutetes, den Fuss im Rist- und Schienbeinbereich sattelförmig überdeckendes Halteelement 96 und eine im Fersenbereich an einem Absatzelement 98 schwenkbar angelenkte Fersenkappe 100 auf. Ein kabelförmiges Spannelement 102 verbindet das Halteelement 96 und die Fersenkappe 100 mit der Spanneinrichtung 76. Das Spannorgan 90 weist zwei Führungsnuten 104 für das Spannelement 102 auf (vergl. auch Fig. 5). Die beiden Führungsnuten 104 verlaufen parallel zueinander und, in einer Richtung parallel zur Sohle 14 und rechtwinklig zur Schuhlängsrichtung A gesehen, nebeneinander vom oberen hinteren Ende des Spannorganes 90 in Schuhlängsrichtung A nach vorne, um das abgerundete vordere Ende des Spannorganes 90 herum auf die der Sohle 14 zugewandte Unterseite und auf dieser Seite zurück zum hinteren Ende des Spannorganes 90. Das eine endlose Schlaufe bildende, kabelförmige Spannelement 102 ist in jeder Führungsnut 104 vom Fersenelement 98 herkommend einmal um das Spannorgan 90 herumgeführt und wird durch dieses in zwei Teilschlaufen 106 und 108 unterteilt.The foot holding device 78 is of the same design as is described in detail in EP-A 0 321 714. This foot holding device 78 has a holding element 96 which is arranged between the shaft 10 and a generally known, padded, padded inner shoe, not shown in the figures, indicated by dashed lines, and covers the foot in the instep and shin area in a saddle-shaped manner, and a heel cap 100 which is pivotably articulated on a heel element 98 on. A cable-shaped tensioning element 102 connects the holding element 96 and the heel cap 100 to the tensioning device 76. The tensioning element 90 has two guide grooves 104 for the tensioning element 102 (cf. also Fig. 5). The two guide grooves 104 run parallel to one another and, viewed in a direction parallel to the sole 14 and perpendicular to the longitudinal direction A of the shoe, next to one another from the upper rear end of the tensioning element 90 in the longitudinal direction A of the shoe around the rounded front end of the tensioning element 90 to that of the sole 14 facing underside and on this side back to the rear end of the tensioning element 90. The cable-shaped tensioning element 102, which forms an endless loop, is guided in each guide groove 104 from the heel element 98 once around the tensioning element 90 and is divided into two partial loops 106 and 108 by this .

In der vorderen Teilschlaufe 106 verläuft das Spannelement 102, bei der einen Führungsnut 104 auf der Oberseite des Spannorganes 90 beginnend, von diesem zum Fersenelement 98 und wird in diesem in einem Führungskanal 110 oder um eine entsprechende Umlenkrolle in Richtung gegen aussen um ca. 180° umgelenkt. Anschliessend überquert das Spannelement 102 das Halteelement 96 im Ristbereich und ist von dort zu einer an der Sohle 14 vorgesehenen Umlenköse 112 geführt. Von der Umlenköse 112 herkommend, übergreift das Spannelement 102 das Halteelement 96 im vorderen Endbereich und ist zu einer weiteren bezüglich der Schuhlängsmittelebene zur Umleknöse 112 symmetrischen weiteren Umlenköse 112 geführt. Von dieser Umlenköse 112 verläuft das Spannelement 102 erneut über das Halteelement 96 im Ristbereich auf die andere Seite des Skischuhs und nach hinten zum Fersenelement 98, wo es wiederum in einem Führungskanal 110 um ca. 180° umgelenkt und der anderen Führungsnut 104 im Spannorgan 90 zugelenkt wird.In the front partial loop 106, the tensioning element 102, starting with a guide groove 104 on the upper side of the tensioning element 90, runs from the latter to the heel element 98 and is in this in a guide channel 110 or around a corresponding deflection roller in the outward direction by approximately 180 ° redirected. The tensioning element 102 then crosses the holding element 96 in the instep area and is guided from there to a deflection eyelet 112 provided on the sole 14. Coming from the deflection eyelet 112, the tensioning element 102 extends over the holding element 96 in the front end region and is guided to a further deflection eyelet 112 which is symmetrical with respect to the longitudinal center plane of the shoe to the deflection eyelet 112. From this deflection eyelet 112, the tensioning element 102 again runs over the holding element 96 in the instep area to the other side of the ski boot and backwards to the heel element 98, where it in turn is deflected by approximately 180 ° in a guide channel 110 and deflected to the other guide groove 104 in the tensioning element 90 becomes.

In der hinteren Teilschlaufe 108 verläuft das kabelförmige Spannelement 102, bei einer Führungsnut 104 auf der Unterseite des Spannorganes 90 beginnend, zum Fersenelement 98 gegen hinten, wo es in einem weiteren Führungskanal 114 bis zu dessen hinteren Ende geführt ist. Von dort verläuft das Spannelement 102 um die Fersenkappe 100 herum auf die andere Seite des Skischuhs, wo es mittels eines an der Fersenkappe 100 angeformten Führungsnoppens 116 geführt ist. Von dort herkommend übergreift das Spannelement 102 das Halteelement 96 in dessen oberen Endbereich und verläuft zu einer entsprechenden Führungsnoppe 116 an der Fersenkappe 100 auf der anderen Seite des Skischuhs. Von dort ist das Spannelement 102 um die Fersenkappe 100 herum auf die andere Seite des Skischuhs geführt, von wo es in einem weitern Führungskanal 114 zur anderen Führungsnut 104 geführt ist. Mit 118 ist ein auf der einen Seite des Skischuhs oberhalb des entsprechenden Gelenks 18 angeordnetes Einstellelement bezeichnet, mit welchem die Länge der endlosen Schlaufe des Spannelementes 102 eingestellt werden kann. Am Fersenelement 98 sind zwei Dämpfungsfedern 120 angeordnet, auf welche die Uebertragungsorgane 86 beim Bewegen in Richtung auf das Fersenelement 98 zu auflaufen.In the rear partial loop 108, the cable-shaped tensioning element 102, starting at a guide groove 104 on the underside of the tensioning element 90, runs to the rear of the heel element 98, where it is guided in a further guide channel 114 to its rear end. From there, the tensioning element 102 extends around the heel counter 100 to the other side of the ski boot, where it is guided by means of a guide knob 116 formed on the heel counter 100. Coming from there, the tensioning element 102 overlaps the holding element 96 in its upper end region and runs to a corresponding guide knob 116 on the heel cap 100 on the other side of the ski boot. From there, the tensioning element 102 is guided around the heel cap 100 to the other side of the ski boot, from where it is guided in a further guide channel 114 to the other guide groove 104. 118 denotes an adjusting element arranged on one side of the ski boot above the corresponding joint 18, with which the length of the endless loop of the tensioning element 102 can be adjusted. Arranged on the heel element 98 are two damping springs 120, onto which the transmission elements 86 run when moving in the direction of the heel element 98.

In den Figuren 6 bis 9 ist die Spanneinrichtung 76 in Draufsicht bzw. Ansicht vereinfacht dargestellt. In den Figuren 6 und 8 befindet sich das Spannorgan 90, in Schuhlängsrichtung A gesehen, in seiner hinteren Lösestellung und in den Figuren 7 und 9 ist es in seiner in Schuhlängsrichtung A gesehen vorderen Spannstellung 90' gezeigt. Der die beiden Betätigungshebel 82 miteinander verbindende Schaft 84 durchdringt die beiden Uebertragungsorgane 86 in den Nuten 88. Die Schwenkbewegung der Betätigungshebel 82 um die Achse 20 und die damit gekoppelte Bewegung der Uebertragungsorgane 86 wird durch die Zahnräder 94 und die Verzahnungen 92 an den Uebertragungsorganen 86 und am Spannorgan 90 in eine entgegengesetzte Bewegung des Spannorganes 90 umgesetzt. Befinden sich die Betätigungshebel 82 in der in den Figuren 6 und 8 gezeigten Schwenklage mit schräg nach vorn verlaufender Längserstreckung des Betätigungshebels 82 so ist das Spannorgan 90 nach hinten in die Lösestellung verschoben. Sind die Betätigungshebel 82 hingegen in die in den Figuren 7 und 9 gezeigte Lage verschwenkt, in welcher die Längserstreckung der Betätigungshebel 82 in Richtung nach schräg hinten verläuft, befindet sich das Spannorgan 90 in seiner vorderen Spannstellung 90'. Die Führungsnuten für das kabelförmige Spannelement 102 im Spannorgan 90 sind mit 104 bezeichnet. Im Fersenelement 98 sind nur die weiteren Führungskanäle 114 für das Spannelement 102 der hinteren Teilschlaufe 108 gestrichelt angedeutet (vergl. Fig. 4). Die Dämpfungsfedern 120 sind mit ihrem hinteren Teilbereich in Sacklöchern 122 im Fersenelement 98 gehalten. Der vordere Teilbereich jeder Dämpfungsfeder 120 steht in Schuhlängsrichtung A gegen vorn über das Fersenelement 98 vor. Beim Verschieben der Uebertragungsorgane 86 von ihrer in den Figuren 6 und 8 gezeigten vorderen Lage in die in den Figuren 7 und 9 dargestellte hintere Lage laufen diese nach ungefähr halbem Verschiebungsweg auf je eine Dämpfungsfeder 120 auf. Diese Dämpfungsfedern 120 ersetzen bzw. ergänzen die Druckfederelemente 66 gemäss den Figuren 1 und 2.In FIGS. 6 to 9, the tensioning device 76 is shown in simplified form in plan view or view. In FIGS. 6 and 8, the tensioning element 90 is seen in the longitudinal direction A of the shoe, in its rear release position and in FIGS. The shaft 84 connecting the two actuating levers 82 to one another penetrates the two transmission elements 86 in the grooves 88. The pivoting movement of the actuating levers 82 around the axis 20 and the movement of the transmission elements 86 coupled therewith, the gear wheels 94 and the toothings 92 on the transmission elements 86 and on the tensioning element 90 convert the movement into an opposite movement of the tensioning element 90. If the actuating levers 82 are in the pivot position shown in FIGS. 6 and 8 with the obliquely forward longitudinal extension of the actuating lever 82, the tensioning element 90 is displaced rearward into the release position. If, on the other hand, the actuating levers 82 are pivoted into the position shown in FIGS. 7 and 9, in which the longitudinal extension of the actuating levers 82 extends obliquely to the rear, the clamping element 90 is in its front clamping position 90 '. The guide grooves for the cable-shaped tensioning element 102 in the tensioning element 90 are designated by 104. In the heel element 98, only the further guide channels 114 for the tensioning element 102 of the rear partial loop 108 are indicated by dashed lines (cf. FIG. 4). The rear partial area of the damping springs 120 is held in blind holes 122 in the heel element 98. The front section of each damping spring 120 projects in the longitudinal direction A of the shoe over the heel element 98. When the transmission members 86 are moved from their front position shown in FIGS. 6 and 8 to the rear position shown in FIGS. 7 and 9, they run onto a damping spring 120 after approximately half the displacement. These damping springs 120 replace or supplement the compression spring elements 66 according to FIGS. 1 and 2.

In den Figuren 6 bis 9 ist der untere Schaftteil 12 und die Sohle 14 nur schematisch angedeutet. Mit 124 ist das Fussbett bezeichnet, welches die Spanneinrichtung 75 überdeckt.The lower shaft part 12 and the sole 14 are only indicated schematically in FIGS. 6 to 9. The footbed, which covers the tensioning device 75, is designated by 124.

Beim Verschieben des Spannorganes 90 in die Spannstellung 90' werden die wirksamen Schlaufenlängen der beiden Teilschlaufen 106 und 108 verkürzt und das Spannelement 102 angespannt. Dabei wird das Halteelement 96 durch die vordere Teilschlaufe 106 in Richtung gegen die Sohle 14 und von der hinteren Teilschlaufe 108 in Richtung gegen die Ferse gezogen. Gleichzeitig wird die Fersenkappe 100 in Richtung gegen vorne verschwenkt. Dies vermittelt dem Skifahrer einen sicheren Halt im Skischuh. Wird hingegen das Spannorgan 90 in die in den Figuren 6 und 8 gezeigte Lösestellung überführt, werden die wirksamen Schlaufenlängen der beiden Teilschlaufen 106 und 108 vergrössert, wodurch das Spannelement 102 freigegeben und das Halteelement 96 sowie die Fersenkappe 100 gelöst wird.When the tensioning element 90 is moved into the tensioning position 90 ', the effective loop lengths of the two partial loops 106 and 108 are shortened and the tensioning element 102 is tensioned. The holding element 96 is pulled by the front partial loop 106 in the direction toward the sole 14 and by the rear partial loop 108 in the direction toward the heel. At the same time, the heel counter 100 is pivoted toward the front. This gives the skier a secure hold in the ski boot. If, on the other hand, the tensioning element 90 is transferred to the release position shown in FIGS. 6 and 8, the effective loop lengths of the two partial loops 106 and 108 are increased, as a result of which the tensioning element 102 is released and the holding element 96 and the heel cap 100 are released.

Zum Einsteigen in den Skischuh wird die Rasteinrichtung 32 (vergl. Fig. 1 bis 3) ausgerastet und der obere Schaftteil 16 aus der bezüglich der Senkrechten 28 zur Sohle 14 nach vorn geneigten Ruhelage entgegen Pfeilrichtung B in die Stehlage 16' verschwenkt. Diese Schwenkbewegung des oberen Schaftteils 16 wird durch die Gelenkzapfen 80 auf die Betätigungshebel 82 übertragen. Diese werden somit in die in den Figuren 6 und 8 gezeigte Lage verschwenkt, was ein Verschieben des Spannorganes 90 in die hintere Lösestellung zur Folge hat. Dann wird der Verschluss 26 geöffnet und der hintere Schaftteil 24 um die Gelenkzapfen 80 nach hinten verschwenkt. Nach dem Einsteigen in den Skischuh wird der hintere Schaftteil 24 wieder geschlossen und mittels des Verschlusses 26 mit dem vorderen Schaftteil 22 verspannt. Dabei verbleibt das Spannorgan 90 in seiner Lösestellung und der Fuss kann sich im Innern des Skischuhs relativ frei bewegen. Für die Abfahrt wird nun der Unterschenkel nach vorn gebeugt, wodurch der obere Schaftteil 16, d.h. der vordere Schaftteil 22 zusammen mit dem hinteren Schaftteil 24, in Pfeilrichtung B nach vorn verschwenkt wird. Sobald die Ruhelage 16 erreicht ist, rastet die Rastzunge 40 an der Nase 36 ein. Diese Schwenkbewegung des oberen Schaftteils 16 hat nun zur Folge, dass die Betätigungshebel 82 in die in den Figuren 7 und 9 gezeigte Lage verschwenkt werden. Dadurch wird das Spannorgan 90 in Schuhlängsrichtung A nach vorn in die Spannstellung 90' überführt, was nun zur Folge hat, dass die wirksamen Schlaufenlängen der beiden Teilschlaufen 106, 108 verkürzt und das Spannelement 102 angespannt wird. Dadurch wird der Fuss des Fahrers im Skischuh sicher gehalten. Nach der Abfahrt wird durch Druck auf den Verbindungsteil 52 des doppelarmigen Hebels 46 die Rasteinrichtung 32 gelöst. Dadurch kann der obere Schaftteil 16 aus der Ruhelage in die mit 16' in der Figur 2 gezeigte Stehlage verschwenkt werden. Diese Schwenkbewegung hat nun zur Folge, dass das Spannorgan 90 in die in den Figuren 8 und 10 gezeigte Lösestellung überführt wird. Das Halteelement 96 und die Fersenkappe 100 wird freigegeben, wodurch der Fuss sich im Innern des Schuhs wieder relativ frei bewegen und erholen kann. Ueberdies wird ein problemloses Gehen mit dem Skischuh ermöglicht. Beim jeweiligen Nachvornebeugen des Unterschenkels wird der Fuss entsprechend der Vorlage des Unterschenkels vom Halteelement 96 und der Fersenkappe 100 fester umschlossen bzw. die Umschliessung wieder gelockert. Bei sich in Stehlage 16' befindendem oberen Schaftteil 16 und damit automatisch gelöstem Spannelement 102 kann problemlos bei nach hinten geklappten hintern Schaftteil 124 in den Skischuh eingestiegen bzw. aus diesem ausgestiegen werden.To get into the ski boot, the latching device 32 (see FIGS. 1 to 3) is disengaged and the upper shaft part 16 is pivoted out of the rest position, which is inclined forwardly with respect to the perpendicular 28 to the sole 14, counter to the direction of the arrow B into the standing position 16 '. This pivoting movement of the upper shaft part 16 is transmitted to the actuating lever 82 by the pivot pin 80. These are thus pivoted into the position shown in FIGS. 6 and 8, which results in the tensioning element 90 being displaced into the rear release position. Then the closure 26 is opened and the rear shaft part 24 is pivoted rearward about the pivot pin 80. After getting into the ski boot, the rear shaft part 24 is closed again and clamped to the front shaft part 22 by means of the closure 26. The clamping member 90 remains in its Release position and the foot can move relatively freely inside the ski boot. For the descent, the lower leg is now bent forward, whereby the upper shaft part 16, ie the front shaft part 22 together with the rear shaft part 24, is pivoted forward in the direction of arrow B. As soon as the rest position 16 is reached, the latching tongue 40 engages on the nose 36. This pivoting movement of the upper shaft part 16 now has the consequence that the actuating lever 82 is pivoted into the position shown in FIGS. 7 and 9. As a result, the tensioning member 90 is moved forward in the shoe longitudinal direction A into the tensioning position 90 ', which now has the consequence that the effective loop lengths of the two partial loops 106, 108 are shortened and the tensioning element 102 is tensioned. This keeps the skier's foot securely in the ski boot. After departure, the locking device 32 is released by pressing on the connecting part 52 of the double-armed lever 46. As a result, the upper shaft part 16 can be pivoted from the rest position into the standing position shown at 16 'in FIG. This pivoting movement now has the consequence that the tensioning element 90 is transferred to the release position shown in FIGS. 8 and 10. The holding element 96 and the heel cap 100 are released, whereby the foot can move and relax relatively freely inside the shoe again. In addition, problem-free walking with the ski boot is made possible. When the lower leg is bent forward, the holding element 96 and the heel cap 100 enclose the foot more firmly or the closure is loosened again in accordance with the presentation of the lower leg. When the upper shaft part 16 is in the standing position 16 'and thus the clamping element is automatically released 102 can be easily entered into or exited from the ski boot with the rear shaft portion 124 folded back.

Es ist denkbar, einen Vorneeinstiegskischuh mit einer Rasteinrichtung auszubilden. Vorteilhafterweise ist diese in diesem Fall zwischen dem unteren Schaftteil und dem hinteren Schaftteil angeordnet. Für einen solchen Skischuh kann entsprechend die Spanneinrichtung für die Fusshalteeinrichtung mit dem hinteren Schaftteil gekoppelt sein.It is conceivable to design a front entry ski boot with a locking device. In this case, it is advantageously arranged between the lower shaft part and the rear shaft part. For such a ski boot, the tensioning device for the foot holding device can be coupled to the rear shaft part.

Die Rasteinrichtung zum lösbaren Halten des oberen Schaftteils in der nach vorn geschwenkten Ruhelage kann auch anders als in den Figuren 1 uns 2 gezeigt ausgebildet sein. So ist es denkbar, die Rastnase an einem am Schlitten schwenkbar gelagerten Rasthebel anzuordnen. Durch Verschwenken des Rastthebels wird die Rastnase ausser Eingriff mit dem Durchlass in der Rastzunge gezogen. Der Rasthebel ist derart vorgespannt, dass er wieder selbsttätig einrastet, sobald der obere Schaftteil 16 in die Ruhelage verschwenkt wird.The latching device for releasably holding the upper shaft part in the rest position pivoted forward can also be designed differently than shown in FIGS. 1 and 2. It is conceivable to arrange the locking lug on a locking lever pivotally mounted on the slide. By pivoting the locking lever, the locking lug is pulled out of engagement with the passage in the locking tongue. The locking lever is pretensioned in such a way that it automatically engages again as soon as the upper shaft part 16 is pivoted into the rest position.

Beim Skischuh gemäss den Figuren 1 bis 3 kann durch verdrehen der Spindel 62 die Ruhelage des oberen Schaftteils 16 bezüglich der Senkrechten 28 eingestellt werden. Falls eine solche Einstellung nicht erwünscht ist, kann die Rastnase fest am untern Schaftteil angeformt und der Hebel am unteren Schaftteil schwenkbar gelagert sein.In the ski boot according to FIGS. 1 to 3, the rest position of the upper shaft part 16 with respect to the vertical 28 can be adjusted by turning the spindle 62. If such a setting is not desired, the Locking lug is integrally formed on the lower part of the shaft and the lever on the lower part of the shaft can be pivoted.

Es ist selbstverständlich auch moglich, den vorderen und den hinteren Schaftteil an voneinander unabhängigen Gelenken am unteren Schaftteil zu lagern. Auch kann die Fusshalteeinrichtung anders ausgebildet sein als dies in der Figur 4 gezeigt ist.Of course, it is also possible to mount the front and rear shaft parts on independent joints on the lower shaft part. The foot holding device can also be designed differently from that shown in FIG. 4.
