Abstract

The invention concerns a ski particularly a touring and/or cross-country ski, with a binding (10) for holding an anterior tongue-shaped extension of the sole of a ski shoe. The binding (10) is formed by a recess (16) provided in the ski body (12) extending in the longitudinal direction of the ski, with a sole latching apparatus (abutments 18, 18'; latching device 20 or locking device 20') for fixing the sole extension and thus the ski shoe in a positively locked and friction-locked manner. The ski binding (10) is thus provided in the ski body (12) in integrated manner, so that no parts protrude above the ski deck area (14). In this way a subsequent mounting of the ski binding (10) is no longer necessary. In addition, the skis can be shipped with the ski binding (10) mounted for conventional skis without binding, tightly packed against each other. Finally, there is no additional friction caused by the ski binding during the cross-country run in somewhat deeper snow.

Description

Die Erfindung betrifft einen Langlauf-Ski mit einer Bindung zum form- und/oder kraftschlüssigen Festhalten eines Skischuhs, wobei die am Skikörper befestigten Bindungsteile im Skikörper versenkt angeordnet sind, derart, daß sie die Skideckfläche nicht überragen.The invention relates to a cross-country ski with a binding for positively and / or non-positively holding a ski boot, the binding parts attached to the ski body being arranged recessed in the ski body in such a way that they do not protrude beyond the ski top surface.

Ein derartiger Langlauf-Ski ist aus der DE-A-2 418 187 bekannt, wobei das bekannte System nicht nur eine Abkehr von den herkömmlichen Skibindungen, sondern auch eine Abkehr von den herkömmlichen Langlauf-Schuhkonstruktionen mit jeweils einem vorderen zungenartigen Sohlenfortsatz darstellt. Die schuhseitigen Bindungsteile sind bei der bekannten Konstruktion an der Unterseite der Laufsohle des Langlauf-Skischuhs montiert, und zwar im Ballenbereich desselben, so daß in entsprechender Weise die Biegelinie im Ballenbereiches des Fußes liegt. Bei einer solchen Anordnung unterliegt das Oberleder des Langlauf-Skischuhs einer starken Verformung, wodurch unnötig Energie vernichtet und wodurch ferner Druck auf den Fuß ausgeübt wird, der das Langlaufen nach einiger Zeit zur Qual werden läßt.Such a cross-country ski is known from DE-A-2 418 187, the known system not only representing a departure from the conventional ski bindings, but also a departure from the conventional cross-country ski constructions, each with a front tongue-like sole extension. The shoe-side binding parts are mounted in the known construction on the underside of the outsole of the cross-country ski boot, in the same area of the ball, so that the bending line lies in the ball area of the foot in a corresponding manner. With such an arrangement, the upper leather of the cross-country ski boot is subject to severe deformation, which unnecessarily dissipates energy and also exerts pressure on the foot, which can make cross-country skiing a torture after some time.

Demgegenüber liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen Langlauf-Ski der eingangs genannten Art so weiterzuentwickeln, daß herkömmliche Langlaufschuhe mit einem vorderen zungenartigen Sohlenfortsatz zur Fixierung am Ski verwendet werden können, derart, daß in herkömmlicher Weise die Biegelinie vor dem Schuh bzw. vor den Zehen des Fußes liegt. Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Maßnahmen des Patentanspruches 1 gelöst.In contrast, the present invention has for its object to further develop a cross-country ski of the type mentioned in such a way that conventional cross-country shoes with a front tongue-like sole extension can be used for fixation on the ski, in such a way that the bending line in front of the shoe or in front in a conventional manner the toes of the foot. This object is achieved by the characterizing measures of claim 1.

Bei der erfindungsgemäßen Lösung sind also sämtliche, am Skikörper befestigten Bindungsteile in diesem versenkt angeordnet, derart, daß sie die Skideckfläche nicht überragen. Dadurch wird der Vorteil der bekannten Lösung nach der DE-A-2 418 887 beibehalten, wonach der Ski nur einen minimalen Transportraum in Anspruch nimmt und keine Gefahr mehr besteht, daß der Ski beim Transport durch die normalerweise auf die Skideckfläche montierte Bindung beschädigt wird. Darüber hinaus erlaubt die erfindungs-gemäße Konstruktion eine Fixierung des Skischuhs am Skikörper in herkömmlicher Weise, derart, daß die Biegelinie vor dem Schuh bzw. vor den Zehen des Fußes liegt, so daß mit einem "langen Schritt" gelaufen werden kann. Schuhverformungen werden dabei auf ein Minimum reduziert; dementsprechend gering sind dadurch bedingte Hnergieverluste sowie Fußschmerzen.In the solution according to the invention, therefore, all of the binding parts fastened to the ski body are arranged sunk in such a way that they do not protrude beyond the ski top surface. This maintains the advantage of the known solution according to DE-A-2 418 887, according to which the ski takes up only a minimal transport space and there is no longer any risk that the ski will be damaged during transport by the binding which is normally mounted on the ski top surface. In addition, the construction according to the invention allows the ski boot to be fixed to the ski body in a conventional manner in such a way that the bending line lies in front of the boot or in front of the toes of the foot, so that a "long step" can be taken. Shoe deformations are reduced to a minimum; the resulting loss of energy and foot pain are accordingly low.

Zur form- und kraftschlüssigen Fixierung des Sohlenfortsatzes bzw. des Skischuhs am Skikörper sind der erfin-dungsgemäß vorgesehenen Ausnehmung ein Widerlager für den Sohlenfortsatz sowie eine Rasteinrichtung zugeordnet, die mit am Sohlenfortsatz angeordneten komplementären Rastmitteln zusammenwirkt. Das Widerlager ist dabei so ausgebildet, daß der Sohlenfortsatz dieses in seiner in die Ausnehmung eingeführten Endlage entweder unter- oder über- bzw. hintergreift.For the positive and non-positive fixing of the sole extension or the ski boot to the ski body, the recess provided according to the invention is assigned an abutment for the sole extension and a locking device which interacts with complementary locking means arranged on the sole extension. The abutment is designed in such a way that the sole extension either engages under or over or behind it in its end position introduced into the recess.

Bei einer bevorzugten konstruktiven Ausführungsform wird das mit dem Sohlenfortsatz zusammenwirkende Widerlager durch einen die Ausnehmung überbrückenden Quersteg gebildet. In diesem Falle definiert das Widerlager die Biegeachse des Sohlenfortsatzes beim Heben der Ferse(vgl. z.B. DE-OS 2 754 005).In a preferred constructional embodiment, the abutment cooperating with the sole extension is formed by a transverse web bridging the recess. In this case, the abutment defines the bending axis of the sole extension when lifting the heel (see e.g. DE-OS 2 754 005).

Als Widerlager kann auch ein in die Ausnehmung hineinragender Vorsprung dienen, wobei dieser Vorsprung sich vorzugsweise an der in Skilängsrichtung gesehen hinteren Querwand der Ausnehmung befindet, so daß er von einem entsprechend ausgebildeten hakenförmigen Ende des Sohlenfortsatzes hintergriffen werden kann. Dieser Vorsprung definiert in Verbindung mit einem zugeordneten Haltemittel die Biegeachse des Sohlenfortsatzes beim Heben der Ferse.A protrusion protruding into the recess can also serve as an abutment, this protrusion preferably being located on the rear transverse wall of the recess as seen in the longitudinal direction of the ski, so that it can be engaged behind by a suitably designed hook-shaped end of the sole extension. This projection, in conjunction with an associated holding means, defines the bending axis of the sole extension when the heel is raised.

Statt des erwähnten einzigen Vorsprunges können auch an beiden Längsseiten der Ausnehmung in diese hineinragende Vorsprünge vorgesehen sein, unter die der vordere Teil oder auch seitlich vorspringende Nasen des Sohlenfortsatzes schiebbar sind. Die Biegeachse des Sohlenfortsatzes beim Heben der Ferse wird bei der letztgenannten Ausführungsform durch die beiden seitlich vorspringenden Nasen des Sohlenfortsatzes gebildet.Instead of the single projection mentioned, projections projecting into the recess can be provided on both longitudinal sides of the recess, under which the front part or laterally projecting lugs of the sole extension can be pushed. The bending axis of the sole extension when lifting the heel is formed in the latter embodiment by the two laterally projecting lugs of the sole extension.

Die der Bindung zugeordnete Rasteinrichtung umfaßt in der Ausnehmung angeordnete Rastmittel, sogenannte Bindungsrastmittel, und diesen zugeordnete bzw. komplementäre Sohlenrastmittel. Diese Rastmittel wirken so miteinander zusammen, daß eine gegenseitige verhakung erzielt wird. Vorzugsweise werden die Sohlenrastmittel durch nach oben ragende Vorsprünge und die Bindungsrastmittel durch nach unten ragende Vorsprünge oder umgekehrt gebildet, die sich miteinander verhaken lassen. Die Sohlenrastmittel können auch den Sohlenfortsatz seitlich überragende Vorsprünge sein, die in entsprechende Ausnehmungen bzw. Vertiefungen an den Seitenwänden der Bindungsausnehmung einschnappbar sind, oder umgekehrt. Die Vorsprünge sind dabei entweder elastisch ausgebildet oder durch ein elastisches Element vorbelastet.The locking device assigned to the binding comprises locking means, so-called binding locking means, arranged in the recess, and sole locking means assigned or complementary thereto. These locking means work together so that a mutual interlocking is achieved. The sole latching means are preferably formed by upwardly projecting projections and the binding latching means by downwardly projecting projections or vice versa, which can be hooked together. The sole latching means can also be projections laterally projecting from the sole extension, which can be snapped into corresponding recesses or depressions on the side walls of the binding recess, or vice versa. The projections are either elastic or preloaded by an elastic element.

In konstruktiver Weiterbildung der Erfindung ist die Ausnehmung eine muldenförmige Vertiefung mit einem etwa trapezförmigen Querschnitt in Skilängsrichtung und einem etwa rechteckigen Querschnitt in Richtung quer zur Skilängsrichtung. Bei Ausbildung des Widerlagers als Quersteg befindet sich dieser dann etwa auf Höhe des hinteren Endes der flachen Sohle der Ausnehmung. Die hintere Schrägfläche der so ausgebildeten Ausnehmung erleichtert das Einführen des Sohlenfortsatzes in die Ausnehmung und unter das Widerlager bzw. den Quersteg hindurch schräg von oben her. Der Skifahrer bzw. Langläufer kann also ohne Schwierigkeiten in die Bindung "einsteigen". In der Ausnehmung zufällig angesammelter Schnee wird durch den Sohlenfortsatz über die vordere Schrägfläche der Ausnehmung aus dieser herausgeschoben.In a further development of the invention, the recess is a trough-shaped depression with an approximately trapezoidal cross section in the longitudinal direction of the ski and an approximately rectangular cross section in the direction transverse to the longitudinal direction of the ski. When the abutment is designed as a transverse web, this is then located approximately at the level of the rear end of the flat sole of the recess. The rear inclined surface of the recess formed in this way facilitates the insertion of the sole extension into the recess and under the abutment or the transverse web obliquely from above. The skier or cross-country skier can therefore "get into" the binding without difficulty. In Snow accidentally accumulated in the recess is pushed out of the recess by the sole extension over the front inclined surface of the recess.

Bei einer bevorzugten Ausbildung der Erfindung umfaßt die Rasteinrichtung einen in Richtung etwa senkrecht zur Skideckfläche elastisch gelagerten Vorsprung, den ein entsprechend geschalteter Vorsprung am freien vorderen Ende des Sohlenfortsatzes zu hintergreifen vermag. Bei genügend weitem Einführen des Sohlenfortsatzes in die Ausnehmung hinein und unter das als Quersteg ausgebildete Widerlager hindurch verrasten bzw. verhaken die beiden Vorsprünge der Rasteinrichtung und des Sohlenfortsatzes.In a preferred embodiment of the invention, the latching device comprises a projection which is elastically mounted in the direction approximately perpendicular to the ski top surface and which a correspondingly switched projection on the free front end of the sole extension can engage behind. If the sole extension is inserted sufficiently far into the recess and under the abutment designed as a crosspiece, the two projections of the latching device and the sole extension latch or catch.

Vorzugsweise ist der Vorsprung der Rasteinrichtung an der Unterseite eines am Skikörper um eine sich etwa quer zur Skilängsrichtung erstreckende Achse drehelastisch gelagerten Betätigungselements angeordnet, vorteilhafterweise angeformt. Diese Art der Rasteinrichtung ist konstruktiv besonders einfach und auch leicht handhabbar. Zum Entriegeln der Rasteinrichtung ist an der Oberseite des Betätigungselementes an dem dem Vorsprung abgewandten Ende eine Kerbe für eine Skistockspitze vorgesehen, derart, daß durch Ausübung von Druck auf die Skistockspitze und damit auf die Kerbe das Betätigungselement in seine Entriegelungs- bzw. Freigabestellung bringbar bzw. verschwenkbar ist. Zwischen der Kerbe und dem Rastvorsprung befindet sich also die Drehachse des Betätigungselementes.The projection of the latching device is preferably arranged, advantageously integrally formed, on the underside of an actuating element mounted on the ski body about an axis extending approximately transversely to the longitudinal direction of the ski. This type of locking device is structurally particularly simple and easy to handle. To unlock the latching device, a notch for a ski pole tip is provided on the top of the actuating element at the end facing away from the projection, such that the actuating element can be brought into its unlocking or release position or by exerting pressure on the ski pole tip and thus on the notch. is pivotable. The axis of rotation of the actuating element is thus between the notch and the locking projection.

Eine besonders einfache Konstruktion der Rasteinrichtung ist dadurch gekennzeichnet, daß das Betätigungselement als ebene Platte ausgebildet und zu beiden Seiten der Ausnehmung am Skikörper über zwei blattfederartige Laschen befestigt ist, die die Drehachse des Betätigungselementes definieren. Die Betätigungsplatte weist an seiner Unterseite an dem dem als Quersteg ausgebildeten Widerlager zugewandten Ende den Rastvorsprung und an seiner Oberseite an dem dem als Quersteg ausgebildeten Widerlager abgewandten vorderen Ende die Kerbe für die Skistockspitze auf. Die Betätigungsplatte ist so angeordnet, daß sie Teil der Skideckfläche bildet. Sie kann dabei so dimensioniert sein, daß sie eine vordere Durchgangsöffnung der Ausnehmung freigibt, durch die in der Ausnehmung eventuell angestauter Schnee durch den von hinten her eingeführten Sohlenfortsatz aus der Ausnehmung herausgeschoben werden kann.A particularly simple construction of the latching device is characterized in that the actuating element is designed as a flat plate and is attached to the ski body on both sides of the recess by means of two leaf spring-like tabs which define the axis of rotation of the actuating element. On its underside, the actuating plate has the latching projection on the end facing the abutment designed as a crossbar and on its upper side on the front end facing away from the abutment designed as a crossbar, the notch for the ski pole tip. The actuator plate is arranged so that it forms part of the ski deck area. It can be dimensioned in such a way that it clears a front through opening of the recess, through which snow which may have accumulated in the recess can be pushed out of the recess through the sole extension inserted from behind.

Es ist jedoch auch denkbar, die Betätigungsplatte so zu dimensionieren, daß bei eingerastetem Sohlenfortsatz die gesamte Ausdehmung über- bzw. abgedeckt ist, so daß Schnee in die Ausnehmung erst gar nicht eindringen kann. Diese Dimensionierung der Betätigungsplatte ist vor allem sinnvoll bei der Ausführungsform gemäß Anspruch 6, bei der als Widerlager ein in die Ausnehmung hineinragender Vorsprung dient, der sich am hinteren Querrand bzw. an der hinteren Seitenwand der Ausnehmung befindet. Darüber hinaus dient bei dieser Ausführungsform die Betätigungsplatte auch mehr als Haltemittel bzw. Abstützung denn als Rastmittel.However, it is also conceivable to dimension the actuating plate such that the entire extension is covered or covered when the sole extension is engaged, so that snow cannot penetrate into the recess in the first place. This dimensioning of the actuating plate is particularly useful in the embodiment according to claim 6, in which serves as an abutment protruding into the recess, which is located on the rear transverse edge or on the rear side wall of the recess. In addition, in this embodiment, the actuating plate also serves more as a holding means or support than as a locking means.

Bei einer anderen Ausführungsform der Erfindung kann die der Ausnehmung bzw. Bindung zugeordnete Rasteinrichtung mindestens einen in der Ausnehmung angeordneten Zapfen umfassen, der mit einer entsprechenden öffnung oder Vertiefung im Sohlenfortsatz zusammenwirkt, wobei der Zapfen von außen her entgegen der Wirkung eines elastischen Elements in seine den Sohlenfortsatz freigebende Stellung bringbar ist.In another embodiment of the invention, the latching device assigned to the recess or binding can comprise at least one pin arranged in the recess, which cooperates with a corresponding opening or recess in the sole extension, the pin countering the effect of an elastic element in its the outside Sole process releasing position can be brought.

Schließlich kann als Mittel zum Fixieren des Sohlenfortsatzes in der Ausnehmung auch eine Klemmeinrichtung vorgesehen sein, die den Sohlenfortsatz im wesentlichen nur kraftschlüssig in der Ausnehmung hält.Finally, a clamping device can also be provided as a means for fixing the sole extension in the recess, which essentially only holds the sole extension in the recess with a force fit.

Auch ist die Anordnung einer herkömmlichen Langlauf-Skibindung mit einem Federbügel in der Ausnehmung denkbar, so lange nur erfindungsgemäß sichergestellt ist, daß die Halte- bzw. Fixiermittel die Skideckfläche nicht überragen.The arrangement of a conventional cross-country ski binding with a spring clip in the recess is also conceivable, as long as it is only ensured according to the invention that the holding or fixing means do not protrude beyond the ski top surface.

Herstellungstechnisch ist von besonderem Vorteil, wenndie Ausnehmung durch ein in den Skikörper einsetzbares Bauteil aus Kunststoff, Edelstahl oder dgl. gebildet ist. Die Verbindung dieses Bauteils mit dem Skikörper erfolgt vorzugsweise durch Klebung, Einschäumung und/oder Verschraubung.From a manufacturing point of view, it is particularly advantageous if the recess is formed by a component made of plastic, stainless steel or the like that can be inserted into the ski body. This component is preferably connected to the ski body by gluing, foaming and / or screwing.

Wenn sowohl das Widerlager als auch die Rasteinrichtung integraler Bestandteil des die Ausnehmung bildenden Bauteils sind, kann die in einem gesonderten Arbeitsgang hergestellte Bindung als Ganzes in eine entsprechende Aushöhlung im Skikörper eingesetzt und mit diesem verbunden, z.B. verklebt, werden.If both the abutment and the locking device are an integral part of the component forming the recess, the binding produced in a separate operation can be inserted as a whole into a corresponding cavity in the ski body and connected to it, e.g. are glued.

Bei Herstellung des Bau- bzw. Einsatzteils aus Kunststoff ist dieses vorzugsweise als einstückiges Bauteil (Spritzgußteil) ausgebildet.When the component or insert is made from plastic, it is preferably designed as a one-piece component (injection molded part).

Zur Erhöhung der Seitenführung des Skischuhs ist die hintere Schrägfläche der Ausnehmung mit mindestens einer sich in Skilängsrichtung erstreckenden Führungsrille oder Führungsnocke versehen, die außerhalb der Ausnehmung in Richtung nach hinten bzw. zum Skiende hin fortgesetzt sein kann und die mit einer entsprechenden Führungsnocke bzw. -rille an der Unterseite der Laufsohle bzw. des vorderen Sohlenfortsatzes derselben zusammenwirkt. Die Führungsrille bzw. Führungsnocke ist also ebenfalls integraler Bestandteil der erfindungsgemäßen Bindung.To increase the lateral guidance of the ski boot, the rear inclined surface of the recess is provided with at least one guide groove or guide cam extending in the longitudinal direction of the ski, which can be continued outside the recess in the direction towards the rear or towards the end of the ski and which has a corresponding guide cam or groove cooperates on the underside of the outsole or the front sole extension thereof. The guide groove or guide cam is thus also an integral part of the binding according to the invention.

Im übrigen entspricht die Breite des zungenförmigen vorderen Sohlenfortsatzes etwa der lichten Weite der Ausnehmung im Skikörper, wodurch ebenfalls eine gewisse Seitenführung des Skischuhs bezüglich des Skis gewährleistet ist.Otherwise, the width of the tongue-shaped front sole extension corresponds approximately to the inside width of the recess in the ski body, which also ensures a certain lateral guidance of the ski boot with respect to the ski.

Bei einem Sohlenfortsatz in der Laufsohlenebene erstreckt sich bei einer hinteren Schrägfläche der integrierten Skibindung der in diese eingesetzte Schuh in unbelastetem Zustand schräg nach oben. Dies führt zu dem überraschenden Vorteil, daß nach dem Abstoß, wenn der Ski hinten angehoben wird, der optimale Winkel zwischen Schuh und Ski einerseits sowie zwischen Ski und Laufebene andererseits erreicht wird.In the case of a sole extension in the outsole plane, the rear of the integrated ski binding extends in the this inserted shoe obliquely upwards in the unloaded state. This leads to the surprising advantage that after the push-off, when the ski is raised at the back, the optimum angle between the shoe and the ski on the one hand and between the ski and the running plane on the other hand is achieved.

Erfindungsgemäß kann der Absatz des Langlaufschuhs etwas höher als gewöhnlich ausgebildet sein, um den Abstand zwischen der Unterseite der Laufsohle und der Skideckfläche im Fersenbereich zu verkleinern und für Abfahrten dem Skifahrer eine gewisse Körpervorlage aufzuprägen. Bei der letztgenannten Lösung kann die Lauffläche des Skischuhs von vorne nach hinten im Querschnitt keilförmig ausgebildet sein.According to the invention, the heel of the cross-country ski boot can be made somewhat higher than usual in order to reduce the distance between the underside of the outsole and the ski top surface in the heel area and to impart a certain body template to the skier for downhill runs. In the latter solution, the tread of the ski boot can be wedge-shaped in cross-section from front to back.

Erfindungsgemäß kann der Sohlenfortsatz jedoch auch etwas nach unten hin abgewinkelt sein, um das Einführen in die Ausnehmung mit hinterer Schrägfläche zusätzlich zu erleichtern.According to the invention, however, the sole extension can also be angled slightly downward in order to additionally facilitate insertion into the recess with a rear inclined surface.

Zur weiteren Erhöhung der Seitenführung des Skischuhs schließt sich an die hintere Schrägfläche der Ausnehmung eine flache Mulde an, deren Breite etwas größer ist als die Breite des Sohlenfortsatzes und dessen Tiefe etwas geringer ist als die Dicke des Sohlenfortsatzes. Diese Mulde dient zur teilweisen Aufnahme des Sohlenfortsatzes und damit zur erhöhten Seitenführung auch bei angehobener Ferse.To further increase the lateral guidance of the ski boot, a flat depression adjoins the rear oblique surface of the recess, the width of which is slightly larger than the width of the sole extension and the depth of which is slightly less than the thickness of the sole extension. This trough is used for partial absorption of the sole extension and thus for increased lateral guidance even when the heel is raised.

Die Anordnung einer flachen Mulde ist insbesondere bei der Ausführungsform vorteilhaft, bei der das Widerlager durch einen am hinteren Querrand der Ausnehmung angeordneten Rastvorsprung gebildet wird, da bei dieser Ausführungsform nur eine unwesentliche Einführung des Sohlenfortsatzes in die Ausnehmung erfolgt. Die seitenstabilisierende Wirkung der Seitenwände der Ausnehmung ist daher bei dieser Ausführungsform relativ gering. Die Seitenführung erfolgt also ganz wesentlich durch die erwähnte, sich unmittelbar an den hinteren Querrand der Ausnehmung anschließende Führungsmulde.The arrangement of a flat trough is particularly advantageous in the embodiment in which the abutment is formed by a latching projection arranged on the rear transverse edge of the recess, since in this embodiment there is only an insignificant insertion of the sole extension into the recess. The side stabilizing effect of the side walls of the recess is therefore relatively low in this embodiment. The lateral guidance thus takes place very substantially through the aforementioned guide trough, which adjoins the rear transverse edge of the recess.

Zur besseren Verankerung des vorstehend genannten integralen Bauteils mit Ausnehmung, Widerlager und gegebenenfalls Rasteinrichtung im Skikörper ist dieses vorzugsweise an der Unterseite mit einem sich in Skilängsrichtung nach hinten erstreckenden und/oder einem sich in Skilängsrichtung nach vorne erstreckenden nasenartigen Vorsprung versehen, der bzw. die eine Art Widerhaken darstellen.For better anchoring of the above-mentioned integral component with recess, abutment and possibly latching device in the ski body, this is preferably provided on the underside with a nose-like projection which extends rearward in the longitudinal direction of the ski and / or a nose-like projection which extends forward in the longitudinal direction of the ski, the one Represent kind of barb.

In Figur 1 ist nur ein Abschnitt des Skikörpers 12 perspektivisch dargestellt, in dem sich die Bindung 10 befindet. Die Skibindung 10 ist als einheitliches Bauteil 32, vorzugsweise aus Kunststoff, ausgebildet, und im Skikörper 12 versenkt angeordnet. Die Oberseite der Skibindung 10 schließt mit der Skideckfläche 14 bündig ab. Über die Skideckfläche 14 vorragende Teile sind nicht vorhanden.In Figure 1, only a portion of the ski body 12 is shown in perspective, in which the binding 10 is located. The ski binding 10 is designed as a unitary component 32, preferably made of plastic, and is sunk in the ski body 12. The top of the ski binding 10 is flush with the ski top surface 14. There are no parts protruding beyond the ski cover area 14.

Das Bauteil 32 umfaßt eine Ausnehmung 16, deren Querschnitt in Skilängsrichtung trapezförmig und in Richtung quer zur Skilängsrichtung rechteckig ist und in die ein entsprechend dimensionierter vorderer zungenförmiger Fortsatz der Sohle eines nicht dargestellten Skischuhs einführbar ist. Der Sohlenfortsatz untergreift dabei ein Widerlager in Form eines die Ausnehmung 16 überbrückenden Quersteges 18, der zugleich die Biegeachse des Sohlenfortsatzes definiert. Der Quersteg 18 erstreckt sich etwa in der Ebene der Skideckfläche 14.The component 32 comprises a recess 16, the cross section of which is trapezoidal in the longitudinal direction of the ski and rectangular in the direction transverse to the longitudinal direction of the ski, and into which a correspondingly dimensioned front tongue-shaped extension of the sole of a ski boot, not shown, can be inserted. The sole extension engages under an abutment in the form of a transverse web 18 bridging the recess 16, which at the same time defines the bending axis of the sole extension. The crosspiece 18 extends approximately in the plane of the ski top surface 14.

An der der Skispitze zugewandten Seite des Quersteges 18 ist in der Ausnehmung 16 eine Rasteinrichtung 20 vorgesehen, die um eine sich quer zur Skilängsrichtung erstreckende Achse 36 drehelastisch gelagerte Betätigungsplatte 26 umfaßt, an deren hinterem Ende sich ein nach unten erstreckender Rastvorsprung 24 befindet. Der Rastvorsprung 24 ist an der Unterseite der Betätigungsplatte 28 angeformt. Er wirkt mit einem entsprechenden nach oben weisenden Rastvorsprung am freien vorderen Ende des in die Ausnehmung 16 einführbaren Sohlenfortsatzes in verriegelnder Weise zusammen. Der Rastvorsprung 24 ist vorzugsweise etwas nach vorne gebogen, während der nach oben weisende komplementäre Rastvorsprung an der Oberseite des Sohlenfortsatzes des nicht dargestellten Skischuhs etwas nach hinten gebogen ist. Dadurch wird eine regelrechte Verhakung der genannten Rastvorsprünge und damit sichere Fixierung des Skischuhs am Ski gewährleistet.On the side of the crossbar 18 facing the ski tip, a latching device 20 is provided in the recess 16, which comprises an actuating plate 26 mounted in a torsionally elastic manner about an axis 36 extending transversely to the longitudinal direction of the ski, at the rear end of which there is a downwardly extending latching projection 24. The locking projection 24 is formed on the underside of the actuating plate 28. It interacts with a corresponding upward locking projection at the free front end of the sole extension which can be inserted into the recess 16 in a locking manner. The locking projection 24 is preferably slightly bent forward, while the upward-facing complementary locking projection on the top of the sole extension of the ski boot, not shown, is slightly curved backwards. This ensures that the latching projections are properly hooked and thus securely fixes the ski boot to the ski.

Die drehelastische Lagerung der Betätigungsplatte 26 am Skikörper bzw. im vorliegenden Fall am Bauteil 32 erfolgt über zwei jeweils zu beiden Seiten der Ausnehmung 18 angeordnete blattfederartige Laschen 28, 30, die zugleich die Drehachse 36 der Betätigungsplatte 26 definieren. Die Betätigungsplatte 26 sowie die blattfederartigen Laschen 28, 30 sind im vorliegenden Ausführungsbeispiel integrale Bestandteile des Bauteils 32. Das gleiche gilt für den Quersteg 18. Somit ist die gesamte Bindung 10 bei dem dargestellten Ausführungsbeispiel ein einstückiges Bau- bzw. Einsatzteil.The torsionally elastic mounting of the actuation plate 26 on the ski body or in the present case on the component 32 takes place via two leaf spring-like tabs 28, 30 which are arranged on both sides of the recess 18 and at the same time define the axis of rotation 36 of the actuation plate 26. The actuating plate 26 and the leaf-spring-like tabs 28, 30 are integral components of the component 32 in the present exemplary embodiment. The same applies to the crossbar 18. Thus, the entire binding 10 is one in the exemplary embodiment shown one-piece component or insert.

Die blattfederartigen Laschen 28, 30 werden, wie die anliegende Zeichnung deutlich erkennen läßt, durch entsprechende L-förmige Einschnitte in den Beitenwandungen des Bauteils 32 erhalten.The leaf spring-like tabs 28, 30, as can be clearly seen in the attached drawing, are obtained by corresponding L-shaped incisions in the side walls of the component 32.

Es ist jedoch genau so gut denkbar, die Befestigungsplatte 26 nur über drehelastische Verbindungsstege, die sich in Richtung der Drehachse bzw. Biegelinie 36 erstrecken, an den beiden Seitenwänden des Bauteils 32 bzw. am Skikörper 12 zu befestigen.However, it is just as well conceivable to fasten the fastening plate 26 to the two side walls of the component 32 or to the ski body 12 only via torsionally elastic connecting webs which extend in the direction of the axis of rotation or bending line 36.

Am vorderen bzw. der Skispitze zugewandten Ende der Betätigungsplatte 26 ist an deren Oberseite eine Kerbe 34 für eine Skistockspitze vorgesehen, derart, daß durch Ausübung von Druck auf die Kerbe die Betätigungsplatte um die Achse 36 in ihre Entriegelungs- bzw. Freigabestellung verschwenkbar ist. Durch Druck auf die Kerbe 34 wird der Rastvorsprung 24 angehoben, so daß der entsprechende Rastvorsprung an der Oberseite des nicht dargestellten Sohlenfortsatzes freigegeben wird.At the front or the ski tip facing end of the actuating plate 26, a notch 34 is provided for a ski pole tip on its upper side, such that the actuating plate can be pivoted about the axis 36 into its unlocking or release position by exerting pressure on the notch. The locking projection 24 is raised by pressure on the notch 34, so that the corresponding locking projection on the upper side of the sole extension, not shown, is released.

Der Boden der Ausnehmung 16 ist in dem dargestellten Ausführungsbeispiel durch eine hintere Schrägfläche 38, eine vordere Schrägfläche 42 und eine Sohle 22 definiert. Die hintere Schrägfläche 38 ist mit einer sich in Skilängsrichtung erstreckende Führungsrille 40 versehen, die sich außerhalb der Ausnehmung 16 in Richtung nach hinten noch etwas fortsetzt, und in die eine entsprechende Führungsnocke an der Unterseite der Laufsohle sowie des vorderen Sohlenfortsatzes des nicht dargestellten Skischuhs eingreift.In the exemplary embodiment shown, the bottom of the recess 16 is defined by a rear inclined surface 38, a front inclined surface 42 and a sole 22. The rear inclined surface 38 is provided with a guide groove 40 which extends in the longitudinal direction of the ski, which continues somewhat outside the recess 16 in the rearward direction, and into which a corresponding guide cam engages on the underside of the outsole and the front sole extension of the ski boot, not shown.

Die drehelastisch am Bauteil 32 bzw. Skikörper 12 gelagerte Betätigungsplatte 26 ist so bemessen, daß eine vordere Durchgangsöffnung zu der Ausnehmung 16 freigehalten ist, durch die sich eventuell in der Ausnehmung 16 befindlicher Schnee herausgeschoben werden kann, wenn der Sohlenfortsatz durch die hintere Einführöffnung der Ausnehmung 16 in diese hinein und unter den Quersteg 18 hindurchgeschoben wird.The actuating plate 26, which is mounted on the component 32 or ski body 12 in a torsionally elastic manner, is dimensioned such that a front through opening to the recess 16 is kept free, through which snow which may be located in the recess 16 can be pushed out when the sole extension passes through the rear insertion opening of the recess 16 is pushed into this and under the crosspiece 18.

Das Bauteil 32 ist im Skikörper 12 vorzugsweise eingeklebt. Es kann jedoch auch lösbar mit dem Skikörper 12 mittels herkömmlicher Schraubverbindungen verbunden sein. Letztgenannte Lösung hat den Vorteil, daß die Bindung 10 z.B. bei Ermüdung der drehelastischen Lagerung der Betätigungsplatte 26 leicht ausgewechselt werden kann.The component 32 is preferably glued into the ski body 12. However, it can also be releasably connected to the ski body 12 by means of conventional screw connections. The latter solution has the advantage that the bond 10 e.g. can be easily replaced when the torsionally elastic mounting of the actuating plate 26 becomes tired.

Durch die Ausnehmung 16 bzw. den Einsatz des Bauteils 32 erfährt der Skikörper im Bereich der Bindung 10 eine gewisse Schwächung. Diese Schwächung kann ohne weiteres durch entsprechende Armierung der Seitenwangen sowie des Untergurts des Skikörpers in diesem Bereich kompensiert werden. Als Armierung dient vorzugsweise eine Glasfaserarmierung. Es sind jedoch auch Federstahl-Armierungen denkbar.The recess 16 and the use of the component 32 cause the ski body to be weakened to a certain extent in the region of the binding 10. This weakening can easily be compensated for in this area by appropriate reinforcement of the side cheeks and the lower flange of the ski body. Glass fiber reinforcement is preferably used as reinforcement. However, spring steel reinforcements are also conceivable.

Wie bereits eingangs dargelegt worden ist, entspricht natürlich die Breite des in die Ausnehmung 16 einführbaren Sohlenfortsatzes etwa der lichten Weite der Ausnehmung 16, wodurch eine gute Seitenführung des Skischuhs unabhängig von der Führungsrille 40 erhalten wird. Die Dicke des Sohlenfortsatzes ist so bemessen, daß er mit dem nach oben weisenden, mit dem Vorsprung 24 der Rasteinrichtung 20 zusammenwirkenden Vorsprung mit geringem Spiel unter dem Quersteg 18 hindurchschiebbar ist.As has already been explained at the outset, the width of the sole extension which can be inserted into the recess 16 of course corresponds approximately to the inside width of the recess 16, as a result of which good lateral guidance of the ski boot is obtained independently of the guide groove 40. The thickness of the sole extension is dimensioned such that it can be pushed under the transverse web 18 with little play with the upward-facing projection, which cooperates with the projection 24 of the latching device 20.

Die dem Skiende zugewandte Fläche des nach unten weisenden Rastvorsprunges 24 ist vorzugsweise nach unten und vorne abgeschrägt. In entsprechender Weise ist die vordere Fläche des an der Oberseite des Sohlenfortsatzes angeformten Rastvorsprunges nach hinten oben abgeschrägt. Auf diese Weise wird das Ausweichen des Rastvorsprunges 24 bzw. der Betätigungsplatte 26 nach oben beim Einführen des Sohlenfortsatzes in die Bindung 10 erleichtert. Umgekehrt wird aber nach Einrasten die Verrastung dadurch nicht beeinträchtigt.The surface of the downward facing locking projection 24 facing the end of the ski is preferably bevelled downwards and forwards. In a corresponding manner, the front surface of the latching projection formed on the top of the sole extension is bevelled backwards and upwards. In this way, the upward deflection of the locking projection 24 or the actuating plate 26 is facilitated when the sole extension is inserted into the binding 10. Conversely, however, the latching is not impaired after it has snapped into place.

Statt der beschriebenen Rasteinrichtung können auch seitlich wirkende Rastmittel vorgesehen sein, die in entsprechende seitliche Kerben des Sohlenfortsatzes einrasten und entgegen der Wirkung eines elastischen Elements wieder in eine Entriegelungsstellung bringbar sind. Auch eine umgekehrte Anordnung der erwähnten Rastmittel ist denkbar.Instead of the latching device described, laterally acting latching means can also be provided, which snap into corresponding lateral notches of the sole extension and can be brought back into an unlocking position against the action of an elastic element. A reverse arrangement of the locking means mentioned is also conceivable.

Die elastischen Elemente-der Rastmittel können dabei so eingestellt werden, daß bei Überschreiten einer vorbestimmten Zugkraft auf den Sohlenfortsatz dieser nach Art einer Sicherheitsbindung selbsttätig freigegeben wird.The elastic elements of the latching means can be set so that when a predetermined tensile force on the sole extension is exceeded, it is automatically released in the manner of a safety binding.

Bei dem Ausführungsbeispiel gemäß den Fig. 2 und 3 sind Teile, die bereits im Zusammenhang mit Fig. 1 beschrieben sind, mit denselben Bezugsziffern versehen. Eine entsprechende Beschreibung erübrigt sich daher.In the exemplary embodiment according to FIGS. 2 and 3, parts which have already been described in connection with FIG. 1 are provided with the same reference numbers. A corresponding description is therefore unnecessary.

Das Ausführungsbeispiel gemäß den Fig. 2 und 3 unterscheidet sich von dem gemäß Fig. 1 im wesentlichen nur dadurch, daß die vordere Schrägfläche 42 der Ausnehmung 16 ersetzt ist durch eine aufrechte bzw. sich vertikal zur Skideckfläche erstreckende vordere Seitenwand 42'. Die Betätigungsplatte 26 ist ferner so dimensioniert, daß sie in ihrer Verriegelungsstellung die Ausnehmung 16 im Bereich zwischen dem Quersteg 1 ß und der vorderen Seitenwand 42' vollständig abdeckt. Schließlich sind bei der Bindung gemäß den Fig. 2 und 3 keine Führungsrillen entsprechend der Führungsrille 40 vorgesehen, sondern zwei erhabene Führungsnocken bzw. -rippen 40'.The exemplary embodiment according to FIGS. 2 and 3 differs from that according to FIG. 1 essentially only in that the front inclined surface 42 of the recess 16 is replaced by an upright or front wall 42 'extending vertically to the ski top surface. The actuating plate 26 is also dimensioned such that, in its locking position, it completely covers the recess 16 in the region between the transverse web 1 β and the front side wall 42 '. Finally, in the binding according to FIGS. 2 and 3, no guide grooves corresponding to the guide groove 40 are provided, but two raised guide cams or ribs 40 '.

Bei der Ausführungsform gemäß den Fig. 2 und 3 ist insbesondere gewährleistet, daß in die Ausnehmung 16 bei verriegelter Laufsohle kein Schnee eindringen kann.In the embodiment according to FIGS. 2 and 3 it is ensured in particular that no snow can penetrate into the recess 16 when the outsole is locked.

Die Ausführungsform gemäß den Fig. 4 und 5 unterscheidet sich von den anhand der Fig. 1 bis 3 beschriebenen Ausführungsformen im wesentlichen dadurch, daß der als Widerlager dienende Quersteg 18 durch einen in die Ausnehmung 16 hineinragenden Vorsprung 18' ersetzt ist, der am hinteren Querrand der Ausnehmung 16 angeordnet ist. Dieser Vorsprung 18' ist von einem entsprechend ausgebildeten hakenförmigen Ende 47 des Sohlenfortsatzes 46 (strichpunktiert dargestellt) hintergreifbar, wie in Fig. 4 schematisch dargestellt. Die Arretierung des Sohlenfortsatzes bzw. des hakenförmigen Endes desselben in der Ausnehmung 16 erfolgt durch ein Halteelement 24', das an dem dem Sohlenfortsatz zugewandten Ende einer drehelastisch gelagerten Betätigungsplatte 26' entsprechend der oben beschriebenen Betätigungsplatte 26 angeformt ist. Das Halteelement 24' ist also über die Betätigungsplatte 26' drehelastisch im Einsatzteil 32 bzw. Skikörper gelagert.The embodiment according to FIGS. 4 and 5 differs from the embodiments described with reference to FIGS. 1 to 3 essentially in that the transverse web 18 serving as an abutment is replaced by a protrusion 18 ′ protruding into the recess 16, which at the rear transverse edge the recess 16 is arranged. This projection 18 'is of a suitably designed one hook-shaped end 47 of the sole extension 46 (shown in broken lines) can be gripped behind, as shown schematically in FIG. 4. The sole extension or the hook-shaped end of the same is locked in the recess 16 by a holding element 24 ', which is formed on the end of a torsionally elastic actuating plate 26' facing the sole extension in accordance with the actuating plate 26 described above. The holding element 24 'is thus mounted on the actuating plate 26' in a torsionally elastic manner in the insert part 32 or ski body.

Bei dem Ausführungsbeispiel gemäß den Fig. 4 und 5 ist das Halteelement 24' als Wulst ausgebildet, wodurch ein gewisses Abrollen des hakenförmigen Endes 47 des Sohlenfortsatzes 46 beim Heben der Ferse über den Wulst gewährleistet ist. Damit das Halteelement 24' bzw. das dem Sohlenfortsatz zugewandte Ende der Betätigungsplatte 26' beim Heben der Ferse durch den Sohlenfortsatz bzw. dessen Ende nicht in die Ausnehmung 16 gedrückt wird, ist das Betätigungselement 26' bzw. das Haltelement 24' über eine Stütze 24" an der Sohle 22 der Ausnehmung 16 abgestützt. Die Stütze 24" wird, wie Fig. 5 erkennen läßt, durch zwei an den Seitenwänden der Ausnehmung 16 angeformte aufrechte Leisten gebildet. Die drehelastische Lagerung der Betätigungsplatte 26' erfolgt wie bei dem oben beschriebenen Betätigungselement 26 über blattfederartige Laschen 28', 30'. Durch diese Laschen wird auch die Drehachse 36' der Betätigungsplatte 26' definiert (Fig. 5).In the embodiment according to FIGS. 4 and 5, the holding element 24 'is designed as a bead, whereby a certain rolling of the hook-shaped end 47 of the sole extension 46 is ensured when the heel is lifted over the bead. So that the holding element 24 'or the end of the actuating plate 26' facing the sole extension is not pressed into the recess 16 when the heel is lifted by the sole extension or its end, the actuating element 26 'or the holding element 24' is via a support 24 "supported on the sole 22 of the recess 16. The support 24", as can be seen in FIG. 5, is formed by two upright strips formed on the side walls of the recess 16. The torsionally elastic mounting of the actuating plate 26 'takes place, as in the actuating element 26 described above, via leaf spring-like tabs 28', 30 '. The axes of rotation 36 'of the actuating plate 26' are also defined by these tabs (FIG. 5).

Durch Ausübung eines Drucks auf die Kerbe 34 wird das Halteelement 24' angehoben und das hakenförmige Ende 47 des Sohlenfortsatzes 46 freigegeben.By exerting pressure on the notch 34, the holding element 24 'is raised and the hook-shaped end 47 of the sole extension 46 is released.

Die Ausführungsform gemäß den Fig. 4 und 5 weist noch eine weitere Besonderheit auf, nämlich eine flache Mulde im Anschluß an den als Widerlager dienenden Vorsprung 18'. Die Breite dieser flachen Mulde 45 ist geringfügig größer als die Breite des Sohlenfortsatzes 46. Die Tiefe der flachen Mulde 45 ist etwas geringer als die Dicke des Sohlenfortsatzes 46. Im übrigen ist, wie Fig. 4 erkennen läßt, die Dicke des Sohlenfortsatzes 46 im Bereich der Mulde 45 größer als im übrigen Bereich. Durch die Mulde 45 wird eine erhöhte Seitenführung erzielt, und zwar auch bei angehobener Ferse. Die Mulde 45 ist insbesondere bei der Ausführungsform gemäß den Fig. 4 und 5 von großer Bedeutung, da bei dieser Ausführungsform die Seitenwände der Ausnehmung 16 eine weit geringere Seitenführung gewährleisten als z.B. bei den Ausführungsformen gemäß den Fig. 1 bis 3.The embodiment according to FIGS. 4 and 5 has yet another special feature, namely a flat trough following the projection 18 'serving as an abutment. The width of this shallow depression 45 is slightly larger than the width of the sole extension 46. The depth of the shallow depression 45 is somewhat less than the thickness of the sole extension 46. Moreover, as can be seen in FIG. 4, the thickness of the sole extension 46 is in the region the trough 45 larger than in the rest of the area. The recess 45 provides increased lateral guidance, even when the heel is raised. The trough 45 is of great importance in particular in the embodiment according to FIGS. 4 and 5, since in this embodiment the side walls of the recess 16 ensure a far less lateral guidance than e.g. in the embodiments according to FIGS. 1 to 3.

Im übrigen sind auch in den Fig. 4 und 5 die im Zusammenhang mit den Fig. 1 bis 3 bereits beschriebenen Teile mit denselben Bezugsziffern gekennzeichnet.4 and 5, the parts already described in connection with FIGS. 1 to 3 are identified by the same reference numerals.

Das Ausführungsbeispiel gemäß Figur 6 unterscheidet sich von dem gemäß den Fig. 4 und 5 nur durch die andere Ausbildung des Halteelements 24' und die komplementäre Ausbildung der diesem Halteelement zugewandten Seite des Sohlenfortsatzes 46. Das Halteelement 24' ist bei dem Ausführungsbeispiel gemäß Fig. 6 durch eine nach oben und vorn geneigte Schrägfläche gebildet. In entsprechender Weise ist die zugewandte Seite des freien Endes des Sohlenfortsatzes 46 geneigt. Auf diese Weise ist sichergestellt, daß beim Anheben der Ferse das Halteelement 24' gegen die Stützleisten 24" gepreßt und das hakenförmige Ende 47 des Sohlenfortsatzes 46 nicht freigegeben wird.The exemplary embodiment according to FIG. 6 differs from that according to FIGS. 4 and 5 only in the different design of the holding element 24 'and the complementary design of the side of the sole extension 46 facing this holding element. The holding element 24' is in the exemplary embodiment according to FIG. 6 formed by an inclined surface inclined upwards and forwards. The facing side of the free end of the sole extension 46 is inclined in a corresponding manner. This ensures that when the heel is raised, the holding element 24 'is pressed against the support strips 24 "and the hook-shaped end 47 of the sole extension 46 is not released.

Bei der Ausführungsform gemäß den Fig. 7 und 8 ist der Sohlenfortsatz 46' nach unten abgewinkelt bzw. dem trapezförmigen Querschnitt der Ausnehmung 16 in Skilängsrichtung angepaßt. Ferner weist der Sohlenfortsatz 46' einen Längsschlitz 57 auf, dessen inneres Ende durch eine etwa kreisrunde öffnung 48 gebildet wird. Statt einer elastisch wirksamen Rast- bzw. Schnappeinrichtung ist eine formschlüssige Verriegelung 20' zur Fixierung des Sohlenfortsatzes 46' in der Ausnehmung 16 vorgesehen. Die Verriegelung 20' umfaßt ein in der Ausnehmung um eine vertikale Achse drehbares Halteelement 49 (Haltescheibe), unter das der Sohlenfortsatz 46' schiebbar ist. An der Unterseite der Haltescheibe 49 ist ein Verriegelungsteil 50 angeformt, dessen Breite etwa der Breite des Längsschlitzes 57 und dessen Länge etwa dem Durchmesser der öffnung 4ß entsprechen. An das Verriegelungsteil 50 wiederum ist eine Drehachse 51 angeformt, die in der Sohle 22 bzw. einem entsprechenden Sohlenlager 52 drehbar gelagert ist. Die Fixierung der Haltescheibe 49 im Sohlenlager 52 erfolgt über eine am freien Ende der Achse 51 befestigte Haltescheibe 53, die mit federbelasteten Arretierungsnocken 54 zusammenwirkt. Die Zusammenwirkung der Haltescheibe 53 mit den Arretierungsnocken 54 erfolgt derart, daß der flache Verriegelungsteil 50 entweder in Skilängsrichtung oder quer dazu arretiert ist. Dabei ist insbesondere wichtig die Arretierung des flachen Verriegelungsteiles 50 in Skiquerrichtung, um ein ungewolltes Herausgleiten des Sohlenfortsatzes aus der Ausnehmung 16 beim Langlaufen, d.h. bei Wechselbelastung, zu verhindern. Zur Betätigung der Verriegelung 20' ist an der Oberseite der Haltescheibe 49 eine etwa kreuzartige Vertiefung vorgesehen, in die z.B. eine entsprechend ausgebildete Skispitze einsetzbar ist. Die kreuzartige Vertiefung ist in den Fig. 7 und 8 mit der Bezugsziffer 55 gekennzeichnet. Es kann jedoch genau so gut ein einfacher Schlitz vorgesehen sein entsprechend dem Schlitz im Kopf einer Schraube.In the embodiment according to FIGS. 7 and 8, the sole extension 46 'is angled downwards or adapted to the trapezoidal cross section of the recess 16 in the longitudinal direction of the ski. Furthermore, the sole extension 46 'has a longitudinal slot 57, the inner end of which is formed by an approximately circular opening 48. Instead of an elastically effective latching or snap-in device, a positive locking 20 'is provided for fixing the sole extension 46' in the recess 16. The lock 20 'comprises a holding element 49 (holding disc) which can be rotated in the recess about a vertical axis and under which the sole extension 46' can be pushed. A locking part 50 is formed on the underside of the holding disc 49, the width of which corresponds approximately to the width of the longitudinal slot 57 and the length corresponds approximately to the diameter of the opening 4ß. In turn, an axis of rotation 51 is integrally formed on the locking part 50, which is rotatably mounted in the sole 22 or a corresponding sole bearing 52. The retaining disc 49 is fixed in the sole bearing 52 via a retaining disc 53 fastened to the free end of the axis 51, which cooperates with spring-loaded locking cams 54. The interaction of the holding disc 53 with the locking cams 54 takes place in such a way that the flat locking part 50 is locked either in the longitudinal direction of the ski or transversely thereto. It is particularly important to lock the flat locking part 50 in the direction of the ski in order to prevent the sole extension from slipping out of the recess 16 during cross-country skiing, i.e. to prevent alternating loads. To actuate the lock 20 ', an approximately cross-shaped recess is provided on the upper side of the holding disc 49, into which e.g. an appropriately trained ski tip can be used. The cross-like depression is identified in FIGS. 7 and 8 with the reference number 55. However, a simple slot can be provided as well as the slot in the head of a screw.

Der Durchmesser der Haltescheibe 49 ist vorzugsweise nur geringfügig kleiner als die Breite der Ausnehmung 16, um eine ausreichende Fixierung des Sohlenfortsatzes in der Ausnehmung 16 sicherzustellen. Der äußere Umfang der Haltescheibe 49 braucht nicht kreisrund zu sein, sondern kann auch die Form eines Ovals aufweisen.The diameter of the holding disk 49 is preferably only slightly smaller than the width of the recess 16 in order to ensure that the sole extension is adequately fixed in the recess 16. The outer circumference of the holding disk 49 need not be circular, but can also have a shape an oval.

Die Ausnehmung 16 ist wie bei den oben beschriebenen Ausführungsformen vorzugsweise ein einstückiges Bauteil, wobei die beschriebene Verriegelung 20' und deren Lagerung getrennt von diesem Bauteil im Skikörper befestigt wird. Es ist jedoch auch denkbar, die Ausnehmung samt Verriegelung und Lagerung derselben als Einbauteil auszuführen und dieses insgesamt in den Skikörper einzusetzen.As in the above-described embodiments, the recess 16 is preferably a one-piece component, the lock 20 ′ described and its mounting being fastened separately from this component in the ski body. However, it is also conceivable to design the recess together with the locking and storage thereof as a built-in part and to insert it overall into the ski body.

Eine sehr einfache Lösung ist dadurch gekennzeichnet, daß am Sohlenfortsatz ein nach oben ragender federbelasteter Druckknopf angeordnet ist, der in einen entsprechend dimensionierten Durchgang (Bohrung) im Quersteg (18) einrastbar ist, wobei die Oberseite des Druckknopfes für den Eingriff der Skistockspitze eine vorzugsweise muldenförmige Vertiefung aufweist. Vorzugsweise ist die Oberseite des Druckknopfs von vorne nach hinten leicht nach oben geneigt, um das Binführen des Sohlenfortsatzes in die Ausnehmung bzw. unter den Quersteg zu erleichtern.A very simple solution is characterized in that an upwardly projecting spring-loaded push button is arranged on the sole extension, which can be snapped into a correspondingly dimensioned passage (bore) in the crossbar (18), the top of the push button being preferably trough-shaped for the engagement of the ski pole tip Has deepening. Preferably, the top of the push button is inclined slightly upward from the front to the rear in order to facilitate the insertion of the sole extension into the recess or under the crossbar.
