Description

Die Erfindung bezieht sich auf einen Skischuh mit einer innerhalb einer äußeren Schale angeordneten Fußhalterung, die durch wenigstens ein Zugglied mit Hilfe mindestens einer an der Schale gelagerten Spanneinrichtung verstellbar ist, die aus einem Wickelkörper für das Zugglied und einer Drehsperre für die die Schale durchsetzende Welle besteht, und bei der der Wickelkörper auf der Welle innerhalb der äußeren Schale angeordnet ist und außerhalb der Schale auf dieser Welle ein Verstellorgan befestigt ist.The invention relates to a ski boot with a foot holder arranged inside an outer shell, which can be adjusted by at least one tension member with the aid of at least one tensioning device mounted on the shell, which consists of a winding body for the tension member and a turnstile for the shaft passing through the shell , and in which the winding body is arranged on the shaft within the outer shell and an adjusting member is attached to the shaft outside the shell.

Ein derartiger Skischuh ist aus der AT-B-374 352 bekannt.Such a ski boot is known from AT-B-374 352.

Da die äußere Schale eines Skischuhs im allgemeinen aus einem Kunststoff mit vergleichsweise hoher Formstabilität besteht, wird zur Anpassung an die jeweilige Fußform zwischen der Schale und dem Fuß eine einstellbare Fußhalterung vorgesehen, die üblicherweise auf den Innenschuh einwirkt. Solche Fußhalterungen werden insbesondere bei Skischuhen erforderlich deren äußere Schale einen geschlossenen Vorfußteil mit einem angelenkten Schaft aufweist, der aus einem Vorderschaftteil und einer abschwenkbaren Fersenklappe zusammengesetzt ist. Bei solchen Skischuhen kann nämlich der Vorfußteil der Schale nicht verstellt werden, so daß eine Anpassung an den Fuß nur über eine gesonderte Fußhalterung möglich ist. Bei bekannten Fußhalterungen (DE-A-2 712 001) wird beispielsweise innerhalb der Schale im Ristbereich ein sattelartiges Druckübertragungsstück vorgesehen, das mit Hilfe von Bändern gegen die Ferse hin verspannt werden kann. Zu diesem Zweck sind an den Bändern Kabeln befestigt, die durch entsprechende Kanäle in der Schale nach außen zu einem im Fersenbereich an der Fersenklappe angelenkten Spannhebel geführt sind so daß über eine Spannhebelbetätigung das Druckübertragungsstück gegen den Innenschuh gezogen werden kann. Um eine Anpassung an unterschiedliche Fußformen und -größen sicherzustellen, ist der Spannhebel mit mehreren Einhängekerben für das Kabel versehen. Diese Einhängekerben erlauben allerdings nur eine stufenweise Verstellung. Eine stufenlose Verstellung kann erreicht werden wenn das Kabel an einem Schraubentrieb angreift, der auf dem Spannhebel gelagert ist. Damit wird jedoch die Spanneinrichtung konstruktiv aufwendig. Abgesehen davon müssen die zum Spannen der Bänder vorgesehenen Kabel durch Kanäle in der Schale geführt werden, wobei Kabelumlenkungen unvermeidbar sind, die einerseits die Betätigung der Spanneinrichtung erschweren und anderseits einen größeren Verschleiß bedingen.Since the outer shell of a ski boot generally consists of a plastic with a comparatively high dimensional stability, an adjustable foot holder is provided between the shell and the foot to adapt to the particular shape of the foot, which usually acts on the inner shoe. Such foot mounts are required in particular for ski boots whose outer shell has a closed forefoot part with a hinged shaft, which is composed of a fore-end part and a swiveling heel flap. In the case of such ski boots, the forefoot part of the shell cannot be adjusted, so that adaptation to the foot is only possible using a separate foot holder. In known foot mounts (DE-A-2 712 001), for example, a saddle-like pressure transmission piece is provided within the shell in the instep area, which can be braced against the heel with the aid of straps. For this purpose, cables are attached to the straps, which are guided through corresponding channels in the shell outwards to a tensioning lever articulated in the heel area on the heel flap so that the pressure transmission piece can be pulled against the inner shoe via a tensioning lever actuation. To ensure adaptation to different foot shapes and sizes, the tensioning lever is provided with several notches for the cable. However, these notches only allow gradual adjustment. Continuous adjustment can be achieved if the cable engages with a screw drive that is mounted on the tensioning lever. However, this makes the tensioning device structurally complex. Apart from this, the cables provided for tensioning the straps must be led through channels in the shell, whereby Cable deflections are unavoidable, which on the one hand complicate the actuation of the tensioning device and on the other hand cause greater wear.

In der eingangs genannten AT-B-374 352 ist für die Fußhalterung eines Skischuhs eine Spanneinrichtung beschrieben, die aus einem innerhalb der äußeren Schale auf einer Welle sitzenden Wickelkörper für das Zugglied und einer Drehsperre für die die Schale durchsetzende Welle besteht. Der Wickelkörper wird dabei aus einer im wesentlichen halbkreisförmigen Wickelscheibe gebildet, die drehfest mit dem verschwenkbaren Schaftteil des Skischuhs verbunden ist, und zwar über die Gelenkachse des verschwenkbaren Schaftteiles, so daß bei einem Verschwenken des Schaftteiles je nach der Schwenkrichtung die Fußhalterung nachgespannt oder gelockert wird. Um bei dem vergleichsweise geringen Schwenkwinkel des schwenkbaren Schaftteiles eine ausreichende Auf- bzw. Abwickellänge für das Zugglied sicherzustellen, muß der Radius der Wickelscheibe verhältnismäßig groß gewählt werden. Die bekannte Spanneinrichtung eignet sich folglich nicht zur Verstellung der Fußhalterung von Hand aus. Es ist zwar die Möglichkeit vorgesehen, die Vorspannung des Zuggliedes über einen außerhalb der Schale drehfest mit der Welle verbundenen Knopf einzustellen, der in verschiedenen Drehstellungen mit einer Verriegelungsscheibe auf dem verschwenkbaren Schaftteil verschraubt werden kann, doch bildet dieser Knopf keinen Drehgriff zum Spannen der Fußhalterung bei angezogenem Schuh. Einerseits wäre hiefür der Hebelarm zum Aufbringen des notwendigen Drehmoments zu groß und anderseits müßte zum Verstellen die Verschraubung zwischen dem Knopf und der Verriegelungsscheibe gelöst und wieder angezogen werden.In the AT-B-374 352 mentioned at the outset, a tensioning device is described for the foot holder of a ski boot, which consists of a winding body for the tension member seated on a shaft within the outer shell and a turnstile for the shaft passing through the shell. The winding body is formed from a substantially semicircular winding disk, which is rotatably connected to the pivotable shaft part of the ski boot, via the hinge axis of the pivotable shaft part, so that when the shaft part is pivoted, depending on the pivoting direction, the foot holder is tightened or loosened. In order to ensure a sufficient winding or unwinding length for the tension member with the comparatively small pivoting angle of the pivotable shaft part, the radius of the winding disk must be selected to be relatively large. The known tensioning device is consequently not suitable for adjusting the foot holder by hand. Although it is possible to adjust the pretension of the tension member via a button connected to the shaft in a rotationally fixed manner outside the shell, which button can be screwed in different rotational positions with a locking disk on the pivotable shaft part, this button does not provide a rotary handle for tensioning the foot holder put on shoe. On the one hand, the lever arm would be too large to apply the necessary torque, and on the other hand the screw connection between the button and the locking disk would have to be loosened and tightened again.

Aus der CH-A 497 864 ist ein Verschluß an einem Skischuh bekannt, der ein als Drehgriff ausgebildetes, mit einem drehbar gelagerten Griffstück versehenes Verstellorgan umfaßt, das um eine eine Antriebswelle senkrecht durchsetzende Drehachse verschwenkbar ist. Darüber hinaus weist das bekannte Verstellorgan eine Drehsperre auf, die aus einem Anschlag besteht, der beim Fixieren des Verstellorgans schalenfest ist. Durch Herunterklappen des Griffstücks tritt dieses in Wirkverbindung mit dem Anschlag. Dieser Verschluß ist einfach in der Handhabung und auch verschleißfest. Er dient jedoch nicht als Spanneinrichtung für eine innerhalb einer äußeren Schale eines Skischuhs angeordnete Fußhalterung. Darüber hinaus sind keine Maßnahmen für eine Drehsperre des hochgeklappten Griffstücks vorgesehen, die die Handhabung des bekannten Verschlusses zusätzlich erleichtern könnten.From CH-A 497 864 a closure on a ski boot is known, which comprises an adjusting element designed as a turning handle, provided with a rotatably mounted handle, which is pivotable about an axis of rotation penetrating a drive shaft perpendicularly. In addition, the known adjusting element has a turnstile which consists of a stop which is fixed to the shell when the adjusting element is fixed. By folding down the handle, it comes into operative connection with the stop. This closure is easy to use and also wear-resistant. However, it does not serve as a tensioning device for an inside of an outer shell of a ski boot arranged foot bracket. In addition, no measures are provided for a turnstile of the folded-up handle, which could additionally facilitate the handling of the known closure.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ausgehend von dem Stand der Technik nach der AT-B 374352 einen Skischuh derart weiterzuentwickeln, daß die Spanneinrichtung leicht von Hand zu bedienen ist, infolge kleiner Abmessungen an einer für das Spannen der Fußhalterung günstigen Stelle der Schale des Skischuhs angebracht werden kann und relativ verschleißfest ist.The present invention is based on the object, based on the prior art according to AT-B 374352, to further develop a ski boot in such a way that the tensioning device is easy to operate by hand, as a result of small dimensions at a location of the shell of the foot that is favorable for tensioning the foot holder Ski boots can be attached and is relatively wear-resistant.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Wickelkörper als Wickelrolle und das Verstellorgan als Drehgriff ausgebildet ist und der Drehgriff ein Griffstück aufweist, das um eine senkrecht zu dieser Welle ausgerichtete Drehachse auf der Welle drehbar gelagert ist und daß die Drehsperre aus wenigstens einem schalenfesten Anschlag besteht, der mit dem gegen die Schale abgeklappten Griffstück zusammenwirkt und daß die Welle axial verschiebbar in der Schale gehalten und gegenüber der Schale federnd abgestützt ist und daß eine Rasteinrichtung vorgesehen ist, die wenigstens einen in entsprechende Rastausnehmungen eingreifenden Rastansatz aufweist, der vorzugsweise am Griffstück angebracht ist.This object is achieved in that the winding body is designed as a winding roll and the adjusting member as a twist grip and the twist grip has a handle that is rotatably mounted on the shaft about an axis of rotation oriented perpendicular to this shaft and that the turnstile consists of at least one shell-fixed stop exists, which cooperates with the handle folded down against the shell and that the shaft is axially displaceably held in the shell and resiliently supported against the shell and that a locking device is provided which has at least one locking lug engaging in corresponding locking recesses, which is preferably attached to the handle is.

Beim Verdrehen der Welle über den Drehgriff wird das Zugglied, üblicherweise ein Kabel oder ein Seil, auf- oder abgewickelt, wodurch sich die Verstellung der Fußhalterung ergibt. Da der Wickelkern der Wickelrolle einen vergleichsweise kleinen Durchmesser aufweisen kann, sind die Stellschritte selbst dann klein, wenn die Drehsperre nur in ausgewählten Drehstellungen der Welle wirksam wird. Der geringe Durchmesser der Wickelrolle macht es außerdem möglich, daß das erforderliche Spannmoment über das Griffstück ohne Schwierigkeiten von Hand aus aufgebracht werden kann. Das über das Zugglied ausgeübte Drehmoment quer zur Welle muß über die Schale abgetragen werden. Dies bereitet jedoch keine Schwierigkeiten, weil einerseits der Abstand der Wickelrolle von der Schaleninnenseite klein gehalten und anderseits die Welle über Stutzplatten zusätzlich an der Schalenoberfläche abgestützt werden kann.When the shaft is rotated via the rotary handle, the tension member, usually a cable or a rope, is wound up or unwound, which results in the adjustment of the foot holder. Since the winding core of the winding roll can have a comparatively small diameter, the adjustment steps are small even if the turnstile is only effective in selected rotational positions of the shaft. The small diameter of the winding roll also makes it possible that the required clamping torque can be applied by hand without difficulty via the handle. The one exercised over the tension member Torque across the shaft must be removed from the shell. However, this presents no difficulties, because on the one hand the distance of the winding roll from the inside of the shell can be kept small and on the other hand the shaft can be additionally supported on the surface of the shell via support plates.

Um die Welle für die Wickelrolle drehfest gegenüber der Schale festzulegen, braucht das Griffstück lediglich gegen die Schale hin abgeklappt zu werden, so daß es vor den hiefür vorgesehenen schalenfesten Anschlag zu liegen kommt, der eine weitere Verdrehung des Griffstückes verhindert. Die schwenkbare Lagerung des Griffstückes bietet darüber hinaus den Vorteil, daß zum Betätigen der Spanneinrichtung das hochgeschwenkte Griffstück gut handhabbar ist, daß nach dem Einstellen der Fußhalterung aber das Griffstück in eine nicht vorragende Sperrlage abgeschwenkt werden kann.In order to fix the shaft for the winding roller in a rotationally fixed manner with respect to the shell, the grip piece only has to be folded down against the shell, so that it comes to lie in front of the provided shell-fixed stop, which prevents further rotation of the grip piece. The pivotable mounting of the handle also has the advantage that the raised handle is easy to handle for actuating the tensioning device, but that after adjusting the foot holder the handle can be pivoted into a non-protruding locking position.

Durch die Maßnahme, daß die Welle, auf der die Wickelrolle angeordnet ist, axial verschiebbar in der Schale gehalten und gegenüber der Schale federnd abgestützt ist und daß vorzugsweise das Griffstück wenigstens einen in entsprechende Rastausnehmungen eingreifenden Rastansatz aufweist, ist eine auch bei hochgeklapptem Griffstück wirksame Drehsperre geschaffen.By the measure that the shaft on which the winding roll is arranged is axially displaceably held in the shell and is resiliently supported with respect to the shell, and that the grip preferably has at least one locking lug engaging in corresponding locking recesses, is an effective turnstile even when the grip is folded up created.

Zum Lösen einer solchen Drehsperre ist das Griffstück mit einer erhöhten Kraft zu verdrehen, um den Rastansatz unter Überwindung der Federkraft aus der Rastausnehmung herausdrehen zu können. Das Einrasten erfolgt beim Erreichen der Raststellung zufolge der federnden Abstützung der Welle von selbst. Eine solche federnde Rasteinrichtung hat also den zusätzlichen Vorteil, daß das Griffstück auch in der hochgeschwenkten Lage in bestimmten Drehstellungen der Welle verrastet wird, was vor allem das Umsetzen der Betätigungshand beim Verdrehen des Griffstückes erleichtert.To release such a turnstile, the handle must be turned with an increased force in order to be able to unscrew the catch from the catch recess while overcoming the spring force. The latching takes place automatically when the latching position is reached due to the resilient support of the shaft. Such a resilient latching device therefore has the additional advantage that the handle is also latched in the pivoted position in certain rotational positions of the shaft, which is particularly the case when the actuating hand is moved when Turning the handle is easier.

Um in einfacher Weise eine Verrastung in jeweils um 90° gegeneinander verdrehten Stellungen zu erreichen, können schließlich die Rastausnehmungen aus zwei sich im Bereich der Welle schneidenden Nuten in der Schale bestehen.In order to achieve a latching in positions rotated by 90 ° relative to one another in a simple manner, the latching recesses can finally consist of two grooves in the shell intersecting in the region of the shaft.

Obwohl ein einziger Anschlag für das Griffstück für eine Drehsperre ausreichen kann, ist es vorteilhaft, zwei Anschläge in einem der Länge des Griffstückes entsprechenden Abstand voneinander beidseits der Welle vorzusehen, so daß das Griffstück zwischen die Anschläge abgeklappt werden kann, weil damit die Belastung der Anschläge kleiner gehalten wird. Außerdem ist eine sichere, gleich wirksame Drehsperre in beiden Drehrichtungen gegeben.Although a single stop for the handle can be sufficient for a turnstile, it is advantageous to provide two stops at a distance corresponding to the length of the handle on both sides of the shaft, so that the handle can be folded down between the stops, because the load on the stops is kept smaller. In addition, there is a secure, equally effective turnstile in both directions of rotation.

Besonders vorteilhafte Konstruktionsverhältnisse werden sichergestellt, wenn das Griffstück zumindest zwei bezüglich seiner Drehachse um den Abklappwinkel gegeneinander versetzte Rastansätze aufweist, weil einer dieser Rastansätze in der hochgeschwenkten Stellung des Griffstückes und der andere in der abgeklappten Lage wirksam werden. Bestehen die Rastansätze aus einem zur Drehachse des Griffstückes parallelen Steg, so wird durch diesen Steg eine vergleichsweise große Abstützfläche gebildet, was günstige Rastverhältnisse mit sich bringt.Particularly advantageous design conditions are ensured if the handle has at least two latching lugs offset with respect to one another with respect to its axis of rotation by the folding angle, because one of these latching lugs takes effect in the pivoted-up position of the handle and the other in the folded-down position. If the locking lugs consist of a web parallel to the axis of rotation of the handle, a comparatively large support surface is formed by this web, which entails favorable locking conditions.

Von den jeweils an eine Spanneinrichtung 6 angeschlossenen Zuggliedern 8 ist aus Übersichtlichkeitsgründen lediglich eines angedeutet. Da die Spanneinrichtung 6 im wesentlichen durch eine Welle 9 gebildet wird, die die Schale 1 durchsetzt und auf der Schaleninnenseite eine Wickelrolle 10 für das Zugglied 8 sowie auf der Schalenaußenseite einen Drehgriff 11 trägt, kann diese Spanneinrichtung überall dort an der Schale 1 angebracht werden, wo eine Abspannung der Fußhalterung 5 erwünscht ist.The outer shell 1 of the ski boot shown in FIG. 1 consists of a forefoot part 2 forming the sole 2a and a shaft articulated on the forefoot part 2, which is composed of a front part 3 of the shaft and the heel flap 4. Since in particular the forefoot part 2 has a closed, non-adjustable shape, a foot holder 5 is provided within the shell 1 to adapt to the respective foot shape and size, which can be adjusted with the aid of a tensioning device 6. This foot holder 5 consists of a lining piece 7 which extends within the shell over the instep area and which can be tensioned via tension members 8. For reasons of clarity, only one of the tension members 8 connected to a tensioning device 6 is indicated. Since the tensioning device 6 is essentially formed by a shaft 9 which passes through the shell 1 and carries a winding roller 10 for the tension member 8 on the inside of the shell and a turning handle 11 on the outside of the shell, this tensioning device can be attached anywhere on the shell 1, where a bracing of the foot holder 5 is desired.

Das Zugglied 8, im Ausführungsbeispiel ein Seil oder Kabel, ist gemäß Fig. 1 von einem schalenfesten Anlenkpunkt 12 über das Futterstück 7 auf die andere Schuhseite zu einer Umlenkrolle 13 und von dieser Umlenkrolle 13 wieder zurück zur Spanneinrichtung 6 geführt, wo es an der Wickelrolle 10 verankert ist. Diese Zuggliedführung hat den Vorteil, daß die Spannung der beiden Zuggliedstränge über die Umlenkrolle 13 ausgeglichen wird und die Verstellung der Fußhalterung über die Spanneinrichtung 6 feinstufiger erfolgen kann, weil die Spanneinrichtung 6 auf beide Zuggliedtrume wirkt und folglich der Stellweg für die Fußhalterung 5 nur dem halben Stellweg der Spanneinrichtung 6 entspricht.The tension member 8, in the exemplary embodiment a rope or cable, is shown in FIG. 1 from a fixed pivot point 12 via the lining piece 7 to the other side of the shoe to a deflection roller 13 and from this deflection roller 13 back to the tensioning device 6, where it is on the winding roller 10 is anchored. This tension member guide has the advantage that the tension of the two tension member strands is compensated for via the deflecting roller 13 and the adjustment of the foot holder via the tensioning device 6 can be carried out more finely because the tensioning device 6 acts on both tension member dreams and consequently the adjustment path for the foot bracket 5 is only half Travel of the tensioning device 6 corresponds.

Um die über die Spanneinrichtung 6 eingestellte Lage der Fußhalterung 5 zu sichern, ist eine Drehsperre für die Welle 9 vorgesehen. Diese Drehsperre besteht gemäß den Fig. 2 und 3 aus zwei beidseitig der Welle 9 vorgesehenen, schalenfesten Anschlägen 14, die mit dem Drehgriff 11 zusammenwirken, der zu diesem Zweck als Griffstück 15 ausgebildet ist, das um eine zur Welle 9 senkrechte Achse 16 auf der Welle 9 drehbar gelagert ist und zwischen die Anschläge 14 abgeklappt werden kann. In der abgeklappten Stellung wird das Griffstück 15 zwischen den Anschlägen 14 gegenüber einer Drehung um die Wellenachse festgehalten. In der in Fig. 2 strichpunktiert angedeuteten, hochgeschwenkten Betätigungsstellung kann das Griffstück jedoch unbehindert verdreht und das Zugglied 8 von der Wickeltrommel 10 abgespult oder auf der Wickeltrommel aufgewickelt werden.In order to secure the position of the foot holder 5 set via the clamping device 6, a turnstile is provided for the shaft 9. This turnstile consists according to FIGS. 2 and 3 of two shells fixed stops 14 provided on both sides of the shaft 9, which cooperate with the rotary handle 11, which is designed for this purpose as a handle 15, which is about an axis 16 perpendicular to the shaft 9 on the Shaft 9 is rotatably mounted and can be folded down between the stops 14. In the folded position, the handle 15 is held between the stops 14 against rotation about the shaft axis. In the dashed-dotted actuation position indicated in FIG. 2, however, the handle can be rotated freely and the tension member 8 can be unwound from the winding drum 10 or wound on the winding drum.

Zusätzlich zu der durch die Anschläge 14 gebildeten Drehsperre ist eine Rasteinrichtung vorgesehen, und zwar bildet das Griffstück 15 am lagerseitigen Ende bezüglich der Drehachse 16 jeweils um den Abklappwinkel gegeneinander versetzte Rastansätze 17 in Form von achsparallelen Stegen, die mit zwei sich im Bereich der Welle 9 schneidenden, nutenartigen Rastausnehmungen 18 zusammenwirken. Um ein federndes Einrasten der Rastansätzte 17 in die Rastausnehmungen 18 zu ermöglichen, ist die Welle 9 axial verschiebbar in der Schale 1 gehalten und stützt sich über eine Feder 19, die im Ausführungsbeispiel als Federring zwischen der Schale 1 und der Wickeltrommel 10 ausgebildet ist, an der Schale 1 ab. In der hochgeschwenkten Stellung des Griffstückes 15 wird folglich beim Einrasten des entsprechenden Rastansatzes 17 in die Rastausnehmungen 18 zufolge der Federbelastung die Welle 9 nach jedem Drehschritt von 90° festgehalten, so daß das Griffstück 15 in diesen Stellungen zum Umgreifen der Betätigungshand ausgelassen werden kann, ohne ein Nachlassen der bereits aufgebrachten Spannung befürchten zu müssen. Der Rasteingriff in der abgeklappten Stellung bewirkt eine Sicherung der abgeklappten Stellung.In addition to the turnstile formed by the stops 14, a latching device is provided, namely that the handle 15 forms on the bearing-side end with respect to the axis of rotation 16 in each case offset latching projections 17 in the form of axially parallel webs, which are in the region of the shaft 9 with two in the region of the shaft 9 intersecting, groove-like recesses 18 cooperate. In order to enable a resilient engagement of the locking projections 17 in the locking recesses 18, the shaft 9 is held axially displaceably in the shell 1 and is supported by a spring 19, which in the exemplary embodiment is designed as a spring ring between the shell 1 and the winding drum 10 the shell 1. In the pivoted-up position of the handle 15, consequently, when the corresponding latching projection 17 snaps into the latching recesses 18 due to the spring loading, the shaft 9 is held in place after each rotation step of 90 °, so that the handle 15 can be omitted in these positions for reaching around the operating hand without fear of a decrease in the tension already applied. The locking engagement in the folded-down position secures the folded-down position.

Wie der Fig. 1 und 2 zu entnehmen ist, ist die Spanneinrichtung 6 an einem Ansatz der Fersenklappe 4 gelagert, damit beim Abschwenken der Fersenklappe die Fußhalterung 5 in eine Freistellung gelangen kann, in der das Herausziehen des Fußes aus dem Vorfußteil 2 erleichtert wird. Durch das Abschwenken der Fersenklappe wird nämlich die Spanneinrichtung 6 im Sinne einer Verlängerung des Zuggliedes 8 um die Anlenkachse der Fersenklappe 4 verschwenkt.As can be seen in FIGS. 1 and 2, the tensioning device 6 is mounted on a shoulder of the heel flap 4 so that when the heel flap is swiveled away, the foot holder 5 can come into a position in which it is easier to pull the foot out of the forefoot part 2. By pivoting the heel flap namely the tensioning device 6 is pivoted in the sense of an extension of the tension member 8 about the pivot axis of the heel flap 4.

Diese Verschwenkung der Spanneinrichtung 6 verlangt aber, daß die Welle 9 den Vorfußteil 2 in einem Langloch durchsetzt, was keinerlei Schwierigkeiten mit sich bringt, da dieses Langloch ja durch einen Ansatz der Fersenklappe 4 abgedeckt wird.However, this pivoting of the tensioning device 6 requires that the shaft 9 passes through the forefoot part 2 in an elongated hole, which does not pose any difficulties, since this elongated hole is covered by an attachment of the heel flap 4.
