Abstract

Die Erfindung betrifft einen Skischuh mit Zentralverschluß (5) bei dem die beiden Spannglieder (7, 8) durch die Zunge (3) abgedeckt und zumindest in ihrem äußeren Bereich (3a, 3b) geführt sind. Dadurch wird die Handhabung des Zentralverschlusses (5) wesentlich erleichtert und zugleich ein Schutz der Spannglieder (7, 8) gegen Vereisung geschaffen.The invention relates to a ski boot with a central closure (5) in which the two tendons (7, 8) are covered by the tongue (3) and are guided at least in their outer area (3a, 3b). This significantly simplifies the handling of the central lock (5) and at the same time protects the tendons (7, 8) against icing.

Description

Die Erfindung betrifft einen Skischuh mit Zentralverschluß entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a ski boot with a central closure according to the preamble of claim 1.

Bei einem bekannten Skischuh mit Zentralverschluß (DE-PS 22 13 720) sind die beiden mit dem drehbaren zentralen Verschlußglied verbundenen Spannglieder als Seilschlingen ausgebildet, die seitlich über die schwenkbare Zunge des Skischuhes vorstehen. Beim Schließen des Skischuhes drückt der Benutzer mit der einen Hand die Zunge mittels des Verschlußgliedes auf die Kunststoffschale, führt mit der anderen Hand die Enden der beiden Seilschlingen in die beiden an der Kunststoffschale angebrachten hakenartigen Elemente und spannt dann die beiden Seilschlingen durch Drehen des Verschlußgliedes.In a known ski boot with a central lock (DE-PS 22 13 720), the two tendons connected to the rotatable central locking member are designed as rope loops which project laterally over the pivotable tongue of the ski boot. When the ski boot is closed, the user presses the tongue on the plastic shell with the locking member with one hand, guides the ends of the two rope loops into the two hook-like elements attached to the plastic shell with the other hand and then tightens the two rope loops by rotating the locking member.

Der Erfindung liegt nun die Aufgabe zugrunde, einen Skischuh der im Oberbegriff des Anspruches 1 vorausgesetzten Art dahin zu verbessern, daß die Handhabung des Zentralverschlusses noch weiter vereinfacht wird.The invention is based on the object of improving a ski boot of the type required in the preamble of claim 1 in such a way that the handling of the central lock is further simplified.

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

Indem die beiden Spannglieder durch die Zunge abgedeckt und geführt sind, entfällt für den Benutzer die oben geschilderte Notwendigkeit, beim Schließen des Skischuhes die Spannglieder mit der einen Hand in die an der Schale des Skischuhes angebrachten hakenartigen Elemente einführen zu müssen. Bei der erfindungsgemäßen Lösung gelangen die beiden Spannglieder vielmehr selbsttätig in Eingriff mit diesen Elementen, wenn der Benutzer die Zunge mittels des Verschlußgliedes auf die Schale drückt und dann das drehbare Verschlußglied im Sinne einer Schließbewegung betätigt. Ebenso erübrigt sich bei der erfindungsgemäßen Ausführung ein Hantieren an den Spanngliedern beim öffnen des Skischuhes; durch einfaches Drehen des Verschlußgliedes (im Sinne einer öffnungsbewegung) und anschließendes Hochschwenken der Zunge wird der Eingriff der Spannglieder mit den an der Schale angebrachten hakenartigen Elementen aufgehoben. Die Handhabung des Zentralverschlusses wird auf diese Weise für den Benutzer sowohl beim Schließen als auch beim öffnen wesentlich erleichtert.Because the two tendons are covered and guided by the tongue, the need for the user, as described above, is eliminated when closing the ski boot with one hand to insert into the hook-like elements attached to the shell of the ski boot. In the solution according to the invention, the two tendons automatically come into engagement with these elements when the user presses the tongue onto the shell by means of the closure member and then actuates the rotatable closure member in the sense of a closing movement. Likewise, in the embodiment according to the invention, there is no need to tamper with the tendons when opening the ski boot; by simply turning the closure member (in the sense of an opening movement) and then pivoting the tongue upward, the engagement of the tendons with the hook-like elements attached to the shell is canceled. In this way, the handling of the central lock is made considerably easier for the user both when closing and when opening.

Ein weiterer Vorteil der erfindungsgemäßen Lösung besteht in dem guten Schutz der abgedeckten Spannglieder gegen Vereisung. Da die Führungen der Spannglieder durch die Zunge nach außen praktisch vollständig abgedeckt sind, ist verhindert, daß sich Schnee oder Eis im Bereich der Spannglieder und der mit den Spanngliedern in Eingriff stehenden, an der Skischuhschale angebrachten hakenartigen Elemente ansetzt und die Betätigung des Zentralverschlusses beim Öffnen oder Schließen behindert.Another advantage of the solution according to the invention is the good protection of the covered tendons against icing. Since the guides of the tendons are practically completely covered by the tongue to the outside, snow or ice is prevented from settling in the area of the tendons and the hook-like elements in engagement with the tendons attached to the ski boot shell and the actuation of the central lock when opening or closing hindered.

Weitere Merkmale der Erfindung sind Gegenstand der Unteransprüche und werden im Zusammenhang mit der Erläuterung einiger Ausführungsbeispiele beschrieben.Further features of the invention are the subject of the dependent claims and are described in connection with the explanation of some exemplary embodiments.

Der in Fig.1 schematisch dargestellte Skischuh enthält einen durch eine Kunststoffschale 1 gebildeten Außenschuh, in dem sich ein (nicht dargestellter) Innenschuh aus Schaumstoff befindet. Die Schale 1 ist im vorderen und oberen Bereich mit einer öffnung 2 versehen, die das Einführen des Innenschuhes in die Schale 1 sowie das Anziehen und Ausziehen des Skischuhes erleichtert.The ski boot shown schematically in FIG. 1 contains an outer boot formed by a plastic shell 1, in which there is an inner boot (not shown) made of foam. The shell 1 is provided in the front and upper area with an opening 2, which facilitates the insertion of the inner boot into the shell 1 and the putting on and taking off of the ski boot.

Die Öffnung 2 der Schale 1 wird durch eine aus Kunststoff bestehende Zunge 3 abgedeckt, die um ein nur schematisch angedeutetes Gelenk 4 schwenkbar ist.The opening 2 of the shell 1 is covered by a tongue 3 made of plastic, which can be pivoted about a joint 4, which is only schematically indicated.

Die Zunge 3 trägt einen im einzelnen nicht veranschaulichten Zentralverschluß 5 mit einem drehbaren Verschlußglied 6.The tongue 3 carries a central lock 5, not shown in detail, with a rotatable lock member 6.

Wie sich aus Fig.2 ergibt, gehören zu dem Zentralverschluß 5 zwei Spannglieder 7, 8, die als Seilsehlingen ausgebildet und in nicht näher dargestellter Weise mit dem drehbaren Verschlußglied 6 verbunden sind. Die Verbindung kann beispielsweise über ein Maltesergetriebe erfolgen, so daß durch Drehen des Verschlußgliedes 6 die wirksame Länge der Spannglieder 7, 8 geändert wird.As can be seen from FIG. 2, the central lock 5 includes two tendons 7, 8, which are designed as rope collars and are connected to the rotatable lock member 6 in a manner not shown. The connection can be made, for example, via a Geneva gear, so that the effective length of the tendons 7, 8 is changed by rotating the closure member 6.

Die Zunge 3 ist in der Höhe des Verschlußgliedes 6 mit zwei seitlichen Fortsätzen 3a, 3b versehen, die zur Abdeckung der beiden Spannglieder 7, 8 dienen.The tongue 3 is provided at the level of the closure member 6 with two lateral extensions 3a, 3b, which serve to cover the two tendons 7, 8.

An ihrer Unterseite ist die Zunge 3 im Bereich der seitlichen Fortsätze 3a, 3b mit Ausnehmungen 9, 10 versehen, die zur Aufnahme der Spannglieder 7, 8 sowie zur Führung von Schiebern 11, 12 dienen. Diese Schieber 11, 12 sind mit den Enden der als Seilschlingen ausgebildeten Spannglieder 7, 8 verbunden. Sie greifen ferner in der aus Fig.3 ersichtlichen Weise mit einem seitlichen Rand (z.B. 11a) in nutartige seitliche Erweiterungen (z.B. 9a) der Ausnehmungen 9 bzw. 10 ein. Die Schieber 11, 12 sind auf diese Weise in den Ausnehmungen 9 und 10 gleitbeweglich geführt und zugleich gegen ein Herausfallen aus diesen Ausnehmungen gesichert.On its underside, the tongue 3 is provided in the area of the lateral extensions 3a, 3b with recesses 9, 10, which are used to hold the tendons 7, 8 and to guide slides 11, 12. These slides 11, 12 are connected to the ends of the tendons 7, 8 designed as rope loops. They also engage in the manner shown in FIG. 3 with a lateral edge (e.g. 11a) in groove-like lateral extensions (e.g. 9a) of the recesses 9 and 10, respectively. In this way, the slides 11, 12 are slidably guided in the recesses 9 and 10 and at the same time secured against falling out of these recesses.

Auf ihrer dem Zentralverschluß 5 zugewandten Innenseite sind die Schieber 11, 12 mit einer halbkreisförmigen Ausnehmung 11b bzw. 12b versehen, die in Eingriff mit hakenartigen Elementen 13, 14 kommt, die fest mit der Schale 1 des Skischuhes verbunden sind.On their inner side facing the central lock 5, the slides 11, 12 are provided with a semicircular recess 11b and 12b, respectively, which comes into engagement with hook-like elements 13, 14 which are firmly connected to the shell 1 of the ski boot.

Wie Fig.4 zeigt, ist das Element 13 (gleiches gilt für das Element 14) in seinem unteren Bereich als Niet ausgebildet und mit einem aus Stahl bestehenden Zugband 15 unter Zwischenfügung einer Platte 16 verbunden. Das Zugband 15 überträgt die auf das Element 13 vom Spannglied 7 ausgeübten Kräfte auf ein im Bereich des Fersenteiles des Skischuhes vorgesehenes Widerlager. Die Platte 16 deckt eine in der Kunststoffschale 1 des Skischuhes vorgesehene Ausnehmung 17 ab, durch die das Element 13 nach außen geführt ist.As FIG. 4 shows, the element 13 (the same applies to the element 14) is designed as a rivet in its lower region and is connected to a tension band 15 made of steel with the interposition of a plate 16. The tension band 15 transmits the forces exerted on the element 13 by the tension member 7 to an abutment provided in the area of the heel part of the ski boot. The plate 16 covers a recess 17 provided in the plastic shell 1 of the ski boot, through which the element 13 is guided to the outside.

Wie Fig.4 erkennen läßt, verjüngt sich das zum Angriff des Spanngliedes 7 bestimmte Element 13 auf der mit dem Schieber 11 in Eingriff kommenden Fläche 13a nach innen hin. Der Schieber 11 ist im Bereich der Ausnehmung 11b mit einer komplementär geformten Abschrägung versehen. Auf diese Weise sind der Schieber 11 und das Element 13 gegen ein versehentliches Lösen gesichert, wenn durch das Spannglied 7 ein Zug in Richtung des Pfeiles 18 auf das mit der Kunststoffschale 1 verbundene Element 13 ausgeübt wird.As can be seen in FIG. 4, the element 13 intended to engage the tendon 7 tapers inwards on the surface 13a which engages with the slide 11. The slide 11 is provided with a complementarily shaped bevel in the region of the recess 11b. In this way, the slide 11 and the element 13 are secured against inadvertent loosening when the tension member 7 exerts a pull in the direction of the arrow 18 on the element 13 connected to the plastic shell 1.

Bei dem in den Fig.5 und 6 dargestellten weiteren Ausführungsbeispiel ist das Element 13' gleichfalls als Niet ausgebildet und unter Zwischenfügung der Platte 16 mit dem Zugband 15 verbunden. Das Element 13' trägt hierbei eine Klappe 19, die um eine Achse 20 begrenzt schwenkbar ist und durch eine (nicht dargestellte) Feder in der Lage gemäß Fig.5 gehalten wird. Die dem Schieber 11 zugewandte Fläche 19a der Klappe 19 ist in der anhand von Fig.4 bereits erläuterten Weise abgeschrägt, ebenso wie die hiermit in Eingriff stehende Fläche des Schiebers 11.In the further exemplary embodiment shown in FIGS. 5 and 6, the element 13 'is likewise designed as a rivet and is connected to the tension band 15 with the interposition of the plate 16. The element 13 'here carries a flap 19 which can be pivoted to a limited extent about an axis 20 and is held in the position according to FIG. 5 by a spring (not shown). The surface 19a of the flap 19 facing the slide 11 is chamfered in the manner already explained with reference to FIG. 4, as is the surface of the slide 11 which is in engagement therewith.

Wenn im geschlossenen Zustand des Zentralverschlusses das Spannglied 7 über den Schieber 11 einen Zug in Richtung des Pfeiles 18 auf die Klappe 19 ausübt, so wird diese Zugkraft über die Achse 20 auf das Element 13' und von diesem auf das Zugband 15 übertragen, da die Wirkungslinie der Zugkraft (Pfeil 18) tiefer als die Schwenkachse 20 liegt. Die Klappe 19 wird somit einwandfrei in der Schließlage gehalten.If, in the closed state of the central lock, the tendon 7 exerts a pull in the direction of arrow 18 on the flap 19 via the slide 11, this tensile force is transmitted via the axis 20 to the element 13 'and from there to the tension band 15, since the Line of action of the pulling force (arrow 18) is lower than the pivot axis 20. The flap 19 is thus held properly in the closed position.

Wird jedoch der Zentralverschluß geöffnet, das Spannglied 7 hierdurch entlastet und die Zunge 3 mit dem von ihr getragenen Spannglied 7 nach vorn geschwenkt (vgl. Fig.6), so wirkt auf die Klappe 19 eine Kraftkomponente, die die Klappe um die Achse 20 gegen die Kraft der (nicht dargestellten) Feder im Uhrzeigersinn verschwenkt. Dadurch wird der Schieber 11 von der Klappe 19 auch dann freigegeben, wenn er sich aus irgendeinem Grunde in der Führungsausnehmung 9 verklemmt haben sollte.However, if the central lock is opened, the tendon 7 is relieved and the tongue 3 with the tendon 7 carried by it is pivoted forward (see FIG. 6), a force component acts on the flap 19, which counteracts the flap about the axis 20 the force of the spring (not shown) is pivoted clockwise. As a result, the slide 11 is released from the flap 19 even if it should have got stuck in the guide recess 9 for some reason.

Bei dem in den Fig.7 und 8 veranschaulichten weiteren Ausführungsbeispiel ist das als Seilschlinge ausgebildete Spannglied 7 (gleiches gilt selbstverständlich auch für das Spannglied 8) unmittelbar in nutartigen seitlichen Erweiterungen 9'a der Ausnehmung 9' geführt. Im Bereich des äußeren Endes des Spanngliedes 7 ist eine rohrförmige, halbrunde Verstärkung 21 über dem das Spannglied 7 bildenden Zugseil angeordnet. Sie gewährleistet, daß das Spannglied 7 erst kurz vor seinem äußeren Ende die zur Gleitführung dienende seitliche Erweiterung 9'a der Ausnehmung 9' verläßt. Das mit der Kunststoffschale 1 verbundene Element 13, mit dem das Spannglied 7 über die rohrförmige Verstärkung 21 in Eingriff kommt, ist in Fig.7 gestrichelt angedeutet.In the further exemplary embodiment illustrated in FIGS. 7 and 8, the tension member 7 designed as a rope loop (the same also applies of course to the tension member 8) is guided directly in groove-like lateral extensions 9'a of the recess 9 '. In the area of the outer end of the tendon 7, a tubular, semicircular reinforcement 21 is arranged above the traction cable forming the tendon 7. It ensures that the tendon 7 only shortly before its outer end leaves the lateral extension 9'a of the recess 9 'used for sliding guidance. The element 13 connected to the plastic shell 1, with which the tensioning element 7 comes into engagement via the tubular reinforcement 21, is indicated by dashed lines in FIG.

Um beim Schließen der Zunge ein glattes Eingreifen der an der Kunststoffschale 1 angebrachten Elemente 13 und 14 in die Ausnehmungen 9 (bzw. 9', 10) der Zuge zu gewährleisten, ist die lichte Weite a (Fig.2, 7) dieser Ausnehmungen deutlich größer als die Breite b der Elemente 13, 14 gewählt.In order to ensure a smooth engagement of the elements 13 and 14 attached to the plastic shell 1 in the recesses 9 (or 9 ', 10) of the train when the tongue is closed, the clear width a (FIG. 2, 7) of these recesses is clear chosen larger than the width b of the elements 13, 14.

Im geöffneten Zustand des Zentralverschlusses ist zwischen dem freien Ende des Spanngliedes und dem zugehörigen Element (z.B. 13) ein lichter Abstand c, vgl. Fig.7, vorhanden. Wird der Zentralverschluß durch Drehen des Verschlußgliedes 6 gespannt, so nähert sich das freie Ende des Spanngliedes 7 dem Element 13 (unter Verkleinerung des Abstandes c bis auf Null), bis schließlich Spannglied 7 (bzw. Schieber 11 oder Verstärkung 21) unter Zugspannung fest am Element 13 anliegt.When the central lock is open, there is a clear distance c between the free end of the tendon and the associated element (e.g. 13), cf. Fig. 7, available. If the central lock is tensioned by turning the locking member 6, the free end of the tensioning member 7 approaches the element 13 (reducing the distance c to zero) until finally tensioning member 7 (or slide 11 or reinforcement 21) under tension is firmly attached Element 13 is present.

Wie die Zeichnung erkennen läßt, sind die Spannglieder 7, 8, die zur Führung der Spannglieder dienenden Teile sowie die mit der Kunststoffschale 1 verbundenen Elemente 13, 14, an denen die Spannglieder 7, 8 angreifen, zuverlässig gegen Vereisung geschützt, da sie an der Unterseite der Zunge angeordnet und vollständig abgedeckt sind.As the drawing shows, the tendons 7, 8, the parts used for guiding the tendons and the elements 13, 14 connected to the plastic shell 1, on which the tendons 7, 8 act, are reliably protected against icing, since they are on the Bottom of the tongue are arranged and completely covered.

Bei dem in Fig.9 dargestellten weiteren Ausführungsbeispiel ist die Zunge 3' an ihrem unteren Ende fest mit der den Außenschuh bildenden Kunststoffschale 1 verbunden. Die (in Fig.9 nicht sichtbaren) Spannglieder 7, 8 des Zentralverschlusses 5 wirken hierbei in gleicher Weise mit hakenartigen Elementen 13, 14 zusammen, die fest mit der Schale 1 des Skischuhes verbunden sind.In the further exemplary embodiment shown in FIG. 9, the tongue 3 'is firmly connected at its lower end to the plastic shell 1 forming the outer shoe. The tendons 7, 8 (not visible in FIG. 9) of the central lock 5 act in the same way with hook-like elements 13, 14 together, which are firmly connected to the shell 1 of the ski boot.

Der Einstieg in den Skischuh erfolgt hierbei mittels eines nach hinten um eine Achse 23 wegschwenkbaren Schalenteiles 22 (eines sog. Spoilers), wobei im angezogenen Zustand der Zusammenhalt der Schale 1, des Schalenteiles 22 und der Zunge 3' durch einen Verschluß 24 bewirkt wird.The entry into the ski boot takes place here by means of a shell part 22 (a so-called spoiler) which can be pivoted backwards about an axis 23, the cohesion of the shell 1, the shell part 22 and the tongue 3 'being brought about by a closure 24 in the tightened state.
