Abstract

A device comprising a ski binding which can be secured to a ski, whereby the ski boot is provided with an engagement element which is located longitudinally in relation to the latter. The engagement element is formed, in the known manner, of a wire material with a plurality of bends, whereby its cross-piece is located at a distance from the front end of the boot and its side-pieces, which are adjacent to the cross-piece, are secured at the front-end region of the sole of the ski boot by free bent-out wire sections. According to the invention, the free wire sections (6, 7) of each side-piece (4, 5) of the engagement element (2) are additionally bent out in the direction of the cross-piece (3) at an angle (alpha), as a result of which a better attachment of the engagement element (2) and distribution of forces is achieved between the engagement element and ski boot (1). Furthermore, according to the invention, the individual side-pieces (4, 5) should be divided into at least two wire sections the direction of which differs from that of the previous or next wire section.

Description

Die Erfindung betrifft eine Vorrichtung zum lösbaren Verbinden eines Skischuhes mit einer auf einem Ski festlegbaren Skibindung nach dem Oberbegriff der Ansprüche 1 bzw.2.2. The invention relates to a device for releasably connecting a ski boot with a ski binding that can be fixed on a ski according to the preamble of claims 1 and 2 respectively.

Aus der NO-138 832 ist es schon seit langem bekannt, das vordere Skischuhende zum lösbaren Verbinden mit einer Skibindung mit einem Einhakelement zu versehen. Eine eingegossene Befestigung eines Einhakelementes in eine Kunststoffsohle ist wiederum aus der DE-AS-2 622 966 bekannt.From NO-138 832 it has long been known to provide the front end of the ski boot with a hooking element for detachable connection to a ski binding. A cast fastening of a hooking element into a plastic sole is again known from DE-AS-2 622 966.

Eine Skibindung der eingangs genannten Art ist beispielsweise in der DE-OS-3 002 874 geoffenbart. Bei dieser bekannten Vorrichtung ist das Einhakelement, in der Draufsicht betrachtet (vgl. Fig.4 dieser Druckschrift), etwa in der Form eines viereckigen Ringes ausgestaltet, wobei die freien Drahtabschnitte jedes Schenkels in Richtung zueinander weisend und miteinander fluchtend abgebogen sind. Obzwar sich diese bekannte Lösung in der Praxis bewährt hat, gibt es doch Anzeichen dafür, daß die angegebene Form des Einhakelementes nicht für alle denkbaren Verbindungsmechanismen die zweckdienlichste ist. Die ähnlich einem Ring verlaufende Form des Einhakelementes läßt auch keine Weiterentwicklung zu, wobei eine solche aus Gründen der praktischen Erfahrung als zweckdienlich erscheint.A ski binding of the type mentioned at the outset is disclosed, for example, in DE-OS-3 002 874. In this known device, the hooking element, viewed in plan view (cf. FIG. 4 of this publication), is designed approximately in the form of a square ring, the free wire sections of each leg pointing in the direction of one another and bent in alignment with one another. Although this known solution has proven itself in practice, there are signs that the specified shape of the hooking element is not the most useful for all conceivable connection mechanisms. The shape of the hooking element, which is similar to a ring, also does not allow any further development, which seems to be expedient for practical experience.

Hier setzt nun die Erfindung ein, die sich die Aufgabe gestellt hat, eine Vorrichtung der eingangs genannten Art derart zu gestalten, daß auch Weiterentwicklungen ermöglicht werden, ohne das Konzept des Verbindens zwischen Skischuh und Skibindung zu verlassen. Darüber hinaus soll auch eine Möglichkeit für die Erfüllung diverser Anordnungen im Raum und eine Anpassungsmöglichkeit für verschiedene Materialverbindungen geschaffen werden.This is where the invention comes in, which has set itself the task of designing a device of the type mentioned at the outset in such a way that further developments are also possible without departing from the concept of connecting the ski boot and ski binding. In addition, a possibility for the fulfillment of various arrangements in the room and an adaptation possibility for different material connections are to be created.

Gelöst wird die gestellte Aufgabe vor allem durch die kennzeichnenden Merkmale der Ansprüche 1 oder 2.The problem is solved primarily by the characterizing features of claims 1 or 2.

Dadurch, daß die abgebogenen freien Drahtabschnitte jedes Schenkels in Richtung zum Quersteg hin noch einmal abgebogen sind, entsteht, bezogen auf die Richtung der Beanspruchung, eine hakenartige Abstützung des Einhakelementes innerhalb des vorderen Bereiches des Skischuhs, so daß auch ungünstige, einseitige Belastungen, die beim Laufen mit dem Skischuh erfahrungsgemäß immer wieder auftreten können, vom Skischuh besser als bei der Lösung nach dem Stande der Technik aufgenommen werden können.Due to the fact that the bent free wire sections of each leg are bent again in the direction of the crossbar, a hook-like support of the hooking element is created within the front region of the ski boot, based on the direction of the stress, so that even unfavorable, one-sided loads which occur when Experience has shown that running with the ski shoe can occur again and again, can be absorbed by the ski shoe better than with the solution according to the prior art.

Durch die Richtungsänderung einander anschließender Drahtabschnitte gemäß den Merkmalen des Anspruches 2 wird, bezogen auf die Richtung der Beanspruchung, ebenfalls eine hakenartige Abstützung des Einhakelementes innerhalb des vorderen Bereiches des Skischuhs herbeigeführt. Darüber hinaus wird dem Einhakelement eine größere Steifigkeit geboten, da die einzelnen Schenkel desselben in sich strebenartig versteift sind.By changing the direction of adjoining wire sections according to the features of claim 2, a hook-like support of the hooking element is also brought about within the front region of the ski boot, based on the direction of the stress. In addition, the hooking element is provided with greater rigidity, since the individual legs of the same are stiffened like struts.

Durch die Merkmale des Anspruches 3 wird eine noch bessere Kraftverteilung erzielt, da die Abstützung des Einhakelementes im gesamten Raum des vorderen Endbereiches des Skischuhs erfolgt.An even better force distribution is achieved by the features of claim 3, since the hooking element is supported in the entire space of the front end region of the ski boot.

Nach den Merkmalen des Anspruches 4 wird eine der Außenform des vorderen Endbereiches des Skischuhs angepaßte Ausgestaltung des Einhakelementes erreicht. Dadurch werden zuzüglich die Seitenflächen des Skischuhs versteift.According to the features of claim 4, a design of the hooking element which is adapted to the outer shape of the front end region of the ski boot is achieved. This also stiffens the side surfaces of the ski boot.

Durch die Merkmale des Anspruches 5 wird wiederum der Belastungskraft dadurch intensiv entgegengewirkt, daß bereits die in Längsrichtung des Skischuhs liegenden Drahtabschnitte der einzelnen Schenkel in in unterschiedliche Richtungen weisende Unterabschnitte aufgeteilt sind.Due to the features of claim 5, the load force is in turn counteracted intensely in that the wire sections of the individual legs lying in the longitudinal direction of the ski boot are already divided into subsections pointing in different directions.

Durch die Erwägung, dem Skischuh ein dem natürlichen Bewegungsablauf des Fußes des Skiläufers entsprechendes Abrollen zu gewährleisten, dienen die Merkmale des Anspruches 6. Durch diese Merkmale wird der über den Bereich der großen Zehe ablaufenden Abrollbewegung des Fußes Rechnung getragen.By considering to ensure that the ski boot rolls off according to the natural movement of the skier's foot, the features of claim 6 serve. These features take into account the rolling movement of the foot over the area of the big toe.

Zur Weiterentwicklung dieses Erfindungsgedankens dienen die Merkmale des Anspruches 7, durch die im vorderen Bereich des Skischuhs eine Versteifung erreicht wird.The features of claim 7, by means of which a stiffening is achieved in the front region of the ski boot, serve to further develop this inventive idea.

Weitere Merkmale, Vorteile und Einzelheiten der Erfindung werden nun anhand der Zeichnung, die mehrere Ausführungsbeispiele zeigt, näher beschrieben. Hiebei zeigen: die Fig. 1 bis 3 eine erste Ausführungsform, mit nach innen zweifach abgebogenen freien Drahtabschnitten der einzelnen Schenkel des Einhakelementes, wobei die Fig. 1 das Einhakelement im eingesetzten Zustand in einen Skischuh in der Draufsicht und die Fig. 2 und 3 das Einhakelement für sich in der Draufsicht bzw. im Aufriß zeigen, die Fig. 4 bis 6 eine weitere Ausgestaltung des ersten Ausführungsbeispieles, mit aus der Ebene des Einhakelementes zusätzlich aufgebogenen Drahtabschnitten der einzelnen Schenkel, ähnlich den Fig. 1 bis 3, die Fig. 7 bis 8 ein drittes Ausführungsbeispiel, wobei die Schenkel des Einhakelementes der äußeren Form des vorderen Endbereiches des Skischuhes entsprechend mehrfach abgewinkelt verlaufend und mit nach außen abgebogenen freien Drahtabschnitten dargestellt sind, ähnlich den Fig. 1 bis 3, die Fig. 10 bis 12 ein viertes Ausführungsbeispiel, bei dem die einzelnen Schenkel des Einhakelementes für sich mehrere Abbiegungen aufweisen, ansonsten ebenfalls mit nach außen abgebogenen freien Drahtabschnitten ähnlich den Fig. 7 bis 9, die Fig. 13 bis 15 eine Anordnung der freien Drahtabschnitte, welche eine Art Schwenkachse bilden, die bezogen auf die Längsachse des Einhakelementes, mit dieser einen spitzen Winkel einschließt, ansonsten ähnlich den Fig. 7 bis 9 und Fig. 16 einen Teilschnitt zu der Ausgestaltung nach der Fig. 13, bei welcher die Laufsohle bis zu jenem Bereich, welcher das Einhakelement aufnimmt, relativ zum weiteren Bereich der Laufsohle versteift ist.Further features, advantages and details of the invention will now be described in more detail with reference to the drawing, which shows several exemplary embodiments. Hiebei show: FIGS. 1 to 3 a first embodiment, with free wire sections of the individual legs of the hooking element bent inwards twice, with FIG. 1 the hooking element in the inserted state in a ski boot in plan view and FIGS. 2 and 3 that 4 to 6 show a further embodiment of the first exemplary embodiment, with wire sections of the individual legs additionally bent out from the plane of the hooking element, similar to FIGS. 1 to 3, FIG. 7 to 8, a third embodiment, the legs of the hooking element corresponding to the outer shape of the front end region of the ski shoe are shown angled several times and are shown with free wire sections bent outwards, similar to FIGS. 1 to 3, FIGS. 10 to 12 a fourth embodiment , in which the individual legs of the hooking element have several bends for themselves , otherwise also with outwardly bent free wire sections similar to FIGS. 7 to 9, FIGS. 13 to 15 an arrangement of the free wire sections which form a kind of pivot axis which, with respect to the longitudinal axis of the hooking element, encloses an acute angle with the latter, otherwise similar to FIGS. 7 to 9 and FIG. 16, a partial section of the embodiment according to FIG. 13, in which the outsole is stiffened relative to the further area of the outsole up to the area which receives the hooking element.

Wie man es dem ersten Ausführungsbeispiel nach den Fig. 1 bis 3 entnehmen kann, ist im vorderen Endbereich 1 eines Skischuhes ein in seiner Gesamtheit mit 2 bezeichnetes Einhakelement in bekannter Weise eingegossen. Dieser vordere Endbereich 1 des Skischuhes besteht ebenfalls in an sich bekannter Weise aus einem Kunststoffmaterial. Das Herstellungsverfahren ist ebenfalls für sich bekannt und bildet keinen Gegenstand vorliegender Erfindung.As can be seen from the first exemplary embodiment according to FIGS. 1 to 3, a hooking element designated in its entirety by 2 is cast in a known manner in the front end region 1 of a ski boot. This front end region 1 of the ski boot also consists of a plastic material in a manner known per se. The manufacturing process is also known per se and is not the subject of the present invention.

Das Einhakelement 2 weist einen Quersteg 3 und zwei an diesen mit Abwinkelungen anschließende Schenkel 4,5 auf. Die freien Drahtabschnitte 6,7 der einzelnen Schenkel 4,5 sind in Richtung zueinander abgebogen und dann zusätzlich unter einem spitzen Winkel a noch einmal in Richtung zum Steg 3 hin abgebogen. Die Größe des Winkels a beträgt bis zu 80°, vorzugsweise 60° - 75°. Im Ausführungsbeispiel ist der besseren Übersicht halber ein Winkel α≡ 20° gezeichnet.The hooking element 2 has a transverse web 3 and two legs 4, 5 adjoining it with bends. The free wire sections 6, 7 of the individual legs 4, 5 are bent towards one another and then additionally bent again at an acute angle a in the direction of the web 3. The size of the angle a is up to 80 °, preferably 60 ° - 75 °. In the exemplary embodiment, for the sake of clarity, an angle α≡ 20 ° is drawn.

Im Ausführungsbeispiel nach den Fig. 4 bis 6 entspricht das Einhakelement 2' im wesentlichen der Ausführungsform nach dem ersten Ausführungsbeispiel mit dem Unterschied, daß die freien Endbereiche 6', 7' der einzelnen Schenkel 4', 5' des Einhakelementes 2' aus der Ebene desselben zusätzlich um den Winkel ß ausgebogen sind. Die Größe des Winkels ß beträgt bis zu 45°, vorzugsweise 15 30°.4 to 6, the hooking element 2 'corresponds essentially to the embodiment according to the first embodiment with the difference that the free end regions 6', 7 'of the individual legs 4', 5 'of the hooking element 2' from the plane are additionally bent out by the angle ß. The size of the angle β is up to 45 °, preferably 15-30 °.

Im Ausführungsbeispiel nach den Fig. 7 bis 9 ist das Einhakelement 2" derart gestaltet, daß die einzelnen Schenkel 4", 5" in drei Drahtabschnitte unterteilt sind. Dabei verlaufen die ersten Drahtabschnitte 4"a, 5"a, welche sich an den Quersteg 3' anschließen, normal zu letzteren, die anschließenden leiten Drahtabschnitte 4"b, 5"b verlaufen unter einem Winkel a nach außen. An die Endbereiche dieser Drahtabschnitte schließen sich wieder gerade Drahtabschnitte 4"c, 5"c an, die mit den vorangehenden Drahtabschnitten einen Winkel 8 bilden. Die freien Drahtabschnitte 6", 7" jedes Schenkels 4", 5" sind in diesem Fall nach außen abgewinkelt. Die Winkeln y und 8 weisen eine Größe von etwa 45° auf.7 to 9, the hooking element 2 "is designed in such a way that the individual legs 4", 5 "are subdivided into three wire sections. The first wire sections 4" a, 5 "a, which are located on the transverse web, run in the process 3 'connect, normal to the latter, the subsequent conductive wire sections 4 "b, 5" b extend outward at an angle a. Straight wire sections 4 "c, 5" c are connected to the end regions of these wire sections, the same as the preceding ones Wire sections form an angle 8. The free wire sections 6 ", 7" of each leg 4 ", 5" are angled outwards in this case. The angles y and 8 have a size of approximately 45 °.

Im Ausführungsbeispiel nach den Fig. 10 bis 12 ist das Einhakelement 2"'an seinen Schenkeln 4"', 5"' mit mehrfachen Abbiegungen versehen. Diese Abbiegungen verlaufen gegensinnig; im gegebenen Ausführungsbeispiel sind die gebogenen Drahtabschnitte 4"'a, 4"'b,4"c, 4"'d bzw. 5"'a, 5"'b, 5"'c, 5"'d erkennbar, wobei die freien Endbereiche 6"' bzw. 7"' an die letzten Drahtabschnitte 4"'d bzw. 5"'d anschließen.10 to 12, the hooking element 2 "'is provided with multiple bends on its legs 4"', 5 "'. These bends run in opposite directions; in the given exemplary embodiment, the bent wire sections 4"' a, 4 "' b, 4 "c, 4" 'd or 5 "' a, 5" 'b, 5 "' c, 5" 'd, the free end regions 6 "' or 7" 'on the last wire sections 4 Connect "'d or 5"' d.

Im Ausführungsbeispiel nach den Fig. 13 bis 15 ist ein Einhakelement 21v erkennbar, welches ähnlich der Ausführungsform nach den Fig. 7 bis 9 ausgestattet ist. Die entsprechenden Drahtabschnitte sind mit 4IVa, 4IVb, 4IVc bzw. 5IVa, 5IVb, 5IVc bezeichnet und wiederum schließen sich die freien Drahtabschnitte 6IV bzw. 7IV an die Drahtabschnitte 4'vc bzw. 5'vc an. Der Unterschied zum Ausführungsbeispiel nach den Fig. 7 bis 9 besteht darin, daß der Schenkel 5IV relativ zum Schenkel 41v verlängert ist, im konkreten Ausführungsbeispiel dadurch, daß der Drahtabschnitt 5IVc länger als der Drahtabschnitt 4IVc ist. Dadurch ergibt sich aber ein Fluchten der freien Drahtabschnitte 6IV, 7IV, die eine idelle Schwenkachse 8 bestimmen, deren Richtung von der Normalen zur Längsachse des Einhakelementes 2 1v abweicht und mit dieser einen spitzen Winkel einschließt. Dadurch ergibt sich aber eine günstige Abrollbewegung, da der Skiläufer erfahrungsgemäß stärker um seine große Zehe im Ballenbereich die Bewegung durchführt als um jenen Ballenbereich, der in Richtung seiner kleinen Zehe liegt.In the exemplary embodiment according to FIGS. 13 to 15, a hooking element 2 1v can be seen , which is equipped similarly to the embodiment according to FIGS. 7 to 9. The respective wire portions b with 4 IV a, 4 IV, 4 IV c bz w. 5 IV a, 5 IV b, 5 IV c and again the free wire sections 6 IV and 7 IV are connected to the wire sections 4 ' v c and 5' v c. The difference to the embodiment according to FIGS. 7 to 9 is that the leg 5 IV is extended relative to the leg 4 1v , in the specific embodiment in that the wire section 5 IV c is longer than the wire section 4 IV c. This results in an alignment of the free wire sections 6 IV , 7 IV , which determine an idle pivot axis 8, the direction of which deviates from the normal to the longitudinal axis of the hooking element 2 1v and encloses an acute angle with the latter. However, this results in a favorable rolling movement, since experience has shown that the skier performs the movement around his big toe in the ball area more than that around the ball area that is in the direction of his small toe.

Dieser Bewegungsablauf wird gemäß Fig. 16 noch dadurch begünstigt, daß jener Bereich der Laufsohle 9, in dem sich das Einhakelement 2IV erstreckt, zum weiteren Bereich dieser Laufsohle 9 aus einem steiferen Material gebildet ist. Diesem Umstand ist in Fig. 16 dadurch Rechnung getragen worden, daß der steifere Bereich mit a und der weitere Bereich der Laufsohle 9 mit b bezeichnet worden sind.16 is further promoted in that the area of the outsole 9 in which the hooking element 2 IV extends is formed from a stiffer material to the further area of this outsole 9. This fact has been taken into account in FIG. 16 by designating the stiffer region with a and the further region of the outsole 9 with b.

Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele eingeschränkt. Es sind weitere Abwandlungen denkbar, ohne den Schutzumfang zu verlassen. So ist beispielsweise möglich, die freien Endbereiche nach den Fig. 7 bis 9 bzw. 10 bis 12 bzw. 13 bis 15 nicht nach außen, sondern nach innen abzubiegen. Es ist weiters denkbar, u.zw. sowohl in der dargestellten als auch in der jetzt erwähnten Form, die freien Endbereiche der einzelnen Schenkel ähnlich der Ausführungsform nach den Fig. 4 bis 6 aus der Ebene des Einhakelementes zusätzlich abzubiegen. Gleichfalls ist es denkbar, diese Abbiegung nicht nach oben, sondern nach unten vorzunehmen, vorausgesetzt, daß hiefür genügend Platz vorhanden ist und dies - aus welchen Gründen auch immer - zweckdienlich erscheint. Schließlich ist es auch bei der Ausführungsform nach den Fig. 1 bis 3 bzw. 4 bis 6 denkbar die Schenkel mit unterschiedlich langen Abmessungen zu gestalten, ähnlich wie dies bei der Ausführungsform nach den Fig. 13 bis 15 vorliegt.The invention is not restricted to the exemplary embodiments shown. Further modifications are conceivable without leaving the scope of protection. For example, it is possible not to bend the free end regions according to FIGS. 7 to 9 or 10 to 12 or 13 to 15 outwards, but inwards. It is also conceivable, etc. both in the form shown and in the form now mentioned, additionally bend the free end regions of the individual legs, similar to the embodiment according to FIGS. 4 to 6, from the plane of the hooking element. Likewise, it is conceivable not to make this turn upwards but downwards, provided that there is sufficient space for this and this - for whatever reason - seems expedient. Finally, it is also conceivable in the embodiment according to FIGS. 1 to 3 or 4 to 6 to design the legs with dimensions of different lengths, similarly as is the case with the embodiment according to FIGS. 13 to 15.

Die Darstellung von Skibindungen, welche zur Verwendung eines Skischuhes mit einem dargestellten Einhakelement geeignet sind, dürfte sich im Hinblick auf die verschiedensten Ausführungsformen von Skibindungen, die mit ähnlichen Skischuhen Verwendung finden können, erübrigen. Ebenso erübrigt sich die nähere Darstellung einer zusätzlichen Verankerung des Einhakelementes in einem Versteifungsstück in der Schuhsohle, wie sie beispielsweise in der DE-OS-3 334 144 beschrieben und gezeigt ist. Diese Druckschrift sei zur Veranschaulichung dessen erwähnt, daß das erfindungsgemäße Einhakelement auch in Verbindung mit einem solchen Aufnahmeteil Verwendung finden kann und auch in Verwendung in dieser Form für sich unter Schutz steht.The representation of ski bindings which are suitable for using a ski boot with a hooking element shown should be unnecessary with regard to the most varied embodiments of ski bindings which can be used with similar ski boots. There is also no need for a more detailed description of an additional anchoring of the hooking element in a stiffening piece in the shoe sole, as described and shown for example in DE-OS-3 334 144. This publication is to illustrate that the hooking element according to the invention can also be used in connection with such a receiving part and is also protected in use in this form.
