  • the bolt is used for pressure or kinking, and there are constructive problems with its dimensioning. If the leg spring forming the latch is too large, difficulties arise when loosening the latch with the ski boot. If, on the other hand, the leg spring is dimensioned too weak, the leg of the spring supporting the pawl can be bent.
  • the object of the invention is to eliminate these disadvantages and to provide solutions in which the bolt is not subjected to pressure or buckling, but only to tension and bending. This leads to better material utilization and the bar can be dimensioned weaker
  • the bolt can be dimensioned briefly, which results in a weight saving.
  • the subject of claim 6 brings with it a saving in material, since a separate spring is superfluous.
  • the construction according to claim 10 brings advantages in terms of the power flow between the pawl and bolt with it.

Description

Die Erfindung bezieht sich auf eine Skibindung gemäß dem Oberbegriff des Anspruches 1 bzw. des Anspruches 11.The invention relates to a ski binding according to the preamble of claim 1 and claim 11.

Eine derartige Skibindung ist bereits bekannt und in der WO 87/03211 (Fig. 14 - 20 u.Kontext) beschrieben. Bei dieser Ausführungsform wird der der Klinke zugeordnete Riegel von einer Schenkelfeder gebildet, deren einer Schenkel im Schwenkteil verankert ist und deren anderer Schenkel mit seinem freien Ende in einer als Raste wirkenden Nut an der Unterseite des Lastarmes der Klinke geführt wird.Such a ski binding is already known and is described in WO 87/03211 (Fig. 14-20 and context). In this embodiment, the latch assigned to the pawl is formed by a leg spring, one leg of which is anchored in the pivoting part and the other leg of which is guided with its free end in a groove acting as a catch on the underside of the load arm of the pawl.

Bei dieser bekannten Ausführung wird der Riegel auf Druck bzw. auf Knickung in Anspruch genommen, wobei sich bei dessen Dimensionierung konstruktive Probleme ergeben. Wird die den Riegel bildende Schenkelfeder zu stark diemensioniert, so ergeben sich Schwierigkeiten beim Lösen des Riegels mit dem Skischuh. Wird hingegen die Schenkelfeder zu schwach dimensioniert, so kann der die Klinke abstützende Schenkel der Feder geknickt werden.In this known embodiment, the bolt is used for pressure or kinking, and there are constructive problems with its dimensioning. If the leg spring forming the latch is too large, difficulties arise when loosening the latch with the ski boot. If, on the other hand, the leg spring is dimensioned too weak, the leg of the spring supporting the pawl can be bent.

Die Erfindung stellt sich die Aufgabe, diese Nachteile zu beseitigen und Lösungen anzugeben, bei denen der Riegel nicht auf Druck bzw. auf Knickung, sondern lediglich auf Zug und Biegung beansprucht wird. Dadurch wird eine bessere Materialausnützung herbeigeführt, und der Riegel kann schwächer dimensioniert werdenThe object of the invention is to eliminate these disadvantages and to provide solutions in which the bolt is not subjected to pressure or buckling, but only to tension and bending. This leads to better material utilization and the bar can be dimensioned weaker

Für diese Aufgabe bieten sich zwei Lösungen an, die im kennzeichnenden Teil des Anspruches 1 bzw. des Anspruches 11 angegeben sind. Dadurch, daß der Riegel in einem Fall als Haken und im anderen Fall als Bügel ausgebildet ist, treten bei beiden Ausführungsformen im wesentlichen nur Zug- und Biegespannungen im Riegel auf, welche leichter zu beherrschen sind, als die gefährlichen Knickspannungen. Außerdem wird in beiden Konstruktionen ein sicherer Halt zwischen dem Riegel und der Raste gewährleistet.For this task there are two solutions, which are specified in the characterizing part of claim 1 and claim 11. Because the bolt is designed in one case as a hook and in the other case as a bracket, in both embodiments essentially only tensile and bending stresses occur in the bolt, which are easier to control than the dangerous buckling stresses. In addition, a secure hold between the bolt and the catch is guaranteed in both designs.

Durch die Merkmale des Anspruches 2 wird die Sicherheit der Skibindung erhöht, da zwei gleichartige Teile die Klinke in ihrer geöffneten Lage festhalten.The features of claim 2 increase the security of the ski binding, since two similar parts hold the pawl in its open position.

Durch die Maßnahme des Anspruches 3 kann (je)der Riegel kurz bemessen werden, wodurch sich eine Gewichtsersparnis ergibt.Due to the measure of claim 3, the bolt can be dimensioned briefly, which results in a weight saving.

Durch das Merkmal des Anspruches 4 wird ein Lösen des festgehaltenen Riegels unmittelbar durch Verschwenken der Schwenkschale herbeigeführt.Due to the feature of claim 4, a release of the held bolt is brought about directly by pivoting the swivel shell.

Die Merkmale des Anspruches 5 ermöglichen eine einfache Befestigung des Riegels an der Klinke.The features of claim 5 allow easy attachment of the bolt to the pawl.

Der Gegenstand des Anspruches 6 bringt eine Materialeinsparung mit sich, da eine gesonderte Feder überflüssig wird.The subject of claim 6 brings with it a saving in material, since a separate spring is superfluous.

Durch die Merkmale der Ansprüche 7 und 12 wird ein gesonderter Ansatz eingespart.The features of claims 7 and 12 save a separate approach.

Durch die Gegenstände der Ansprüche 8 und 9 wird gegenüber den vorhergehenden Ausgestaltungen die Gesamtmasse der Klinke verringert und dadurch deren Verschwenken erleichtert.Due to the subject matter of claims 8 and 9, the overall mass of the pawl is reduced in comparison with the previous embodiments, thereby facilitating its pivoting.

Die Konstruktion nach Anspruch 10 bringt Vorteile hinsichtlich des Kraftflusses zwischen Klinke und Riegel mit sich.The construction according to claim 10 brings advantages in terms of the power flow between the pawl and bolt with it.

Die Maßnahme des Anspruches 13 ermöglicht ein Lösen des Hakens, ohne daß hiefür an der Schwenkschale ein gesonderter Nocken angebracht werden müßte.The measure of claim 13 enables the hook to be released without a separate cam having to be attached to the swivel shell for this purpose.

Der Gegenstand des Anspruches 14 bringt eine Vereinfachung im Aufbau der Skibindung mit sich.The subject matter of claim 14 simplifies the construction of the ski binding.

Durch die Maßnahme des Anspruches 15 wird auch bei der Konstruktion mit einem Bügel ein gesonderter Ansatz eingespart.The measure of claim 15 also saves a separate approach in the construction with a bracket.

Das Merkmal des Anspruches 16 ermöglicht eine Verkürzung und damit eine schwächere Dimensionierung des Drahtbügels.The feature of claim 16 enables a shortening and thus a weaker dimensioning of the wire bracket.

Durch die Maßnahme des Anspruches 17 wird die Elastizität des Drahtbügels erhöht.By the measure of claim 17, the elasticity of the wire bracket is increased.

In den Fig. 1 - 4 ist die Skibindung in ihrer Gesamtheit mit 101 bezeichnet. Sie besitzt eine Grundplatte 102, die im Querschnitt zumindest teil-weise U-förmig ist. In den beiden nach oben ragenden Schenkeln 102a der Grundplatte 102 ist eine erste Querachse 103 gelagert. Die Grundplatte 102 ist mittels Schrauben 102b auf der Oberseite 100a eines Langlaufski 100 befestigt.1-4, the ski binding is designated 101 in its entirety. It has a base plate 102 which is at least partially U-shaped in cross section. In the two after A first transverse axis 103 is mounted on the legs 102a of the base plate 102 projecting above. The base plate 102 is fastened to the top 100a of a cross-country ski 100 by means of screws 102b.

Auf der Querachse 103 sind eine Schwenkschale 104 und ein als Winkelhebel ausgebildeter Schwenkteil 105 gelagert. Die Schwenkschale 104 besteht aus einer Basis 104a, aus zwei auf diese lotrechten Seitenwänden 104b₁, 104b₂ und aus einem Quersteg 104c, der die Seitenwände 104b₁,104b₂ verbindet und in dem eine Nut 104d ausgespart ist. Die Schwenkschale 104 dient in bekannter Weise zur Aufnahme des vorderen Endes eines nicht dargestellten Skischuhs sowie eines an dieses Ende angesetzten Einhakelementes. In der Basis 104a der Schwenkschale 104 ist eine Durchbrechung 104e vorgesehen, welche zum Durchtritt eines Verriegelungszapfens 106 dient, der vom waagrechten Schenkel 105a des Schwenkteiles 105 nach oben ragt und der bei geschlossener Skibindung 101 den Freiraum zwischen dem Einhakelement und der Schuhspitze durchsetzt. Der andere, nach oben gerichtete Schenkel 105b des Schwenkteiles 105 trägt eine weitere Querachse 107, auf der eine Klinke 108 schwenkbar gelagert ist. Diese Klinke 108 ist als zweiarmiger Hebel ausgebildet, wobei der eine, als Lastarm wirksame Hebelarm 108a eine Rastnase 108c trägt, wogegen der andere, als Kraftarm wirkende Hebelarm 108b eine Vertiefung 109 zum Einsetzen der Spitze eines nicht dargestellten Skistockes besitzt. Schwenkschale 104 und Schwenkteil 105 stehen unter dem Einfluß einer als Schenkelfeder ausgebildeten Öffnungsfeder 110, welche auf der ersten Querachse 103 gelagert ist und welche die Schwenkschale 104 nach oben drückt. Außerdem steht der Schwenkteil 105 unter dem Einfluß einer vorzugsweise als Gummi- oder Kunststoffblock ausgebildeten Gehfeder 111, welche den waagrechten Schenkel 105a des Schwenkteiles 105 gegen die Grundplatte 102 zu schwenken trachtet. Die Klinke 108 wird von einer als Schenkelfeder ausgebildeten Schließfeder 112 belastet, welche die Rastnase 108c der Klinke 108 in die Nut 104d der Schwenkschale 104 zu drücken sucht.A swivel shell 104 and a swivel part 105 designed as an angle lever are mounted on the transverse axis 103. The swivel shell 104 consists of a base 104a, two on these vertical side walls 104b₁, 104b₂ and a crossbar 104c which connects the side walls 104b₁, 104b₂ and in which a groove 104d is recessed. The swivel shell 104 is used in a known manner for receiving the front end of a ski boot, not shown, and a hooking element attached to this end. In the base 104a of the swivel shell 104, an opening 104e is provided which serves for the passage of a locking pin 106 which projects upwards from the horizontal leg 105a of the swivel part 105 and which, when the ski binding 101 is closed, penetrates the space between the hooking element and the toe of the shoe. The other, upwardly directed leg 105b of the pivoting part 105 carries a further transverse axis 107, on which a pawl 108 is pivotally mounted. This pawl 108 is designed as a two-armed lever, one lever arm 108a, which acts as a load arm, carries a detent 108c, whereas the other lever arm 108b, which acts as a force arm, has a recess 109 for inserting the tip of a ski pole, not shown. Swivel shell 104 and swivel part 105 are under the influence of an opening spring 110 which is designed as a leg spring and which is mounted on the first transverse axis 103 and which presses the swivel shell 104 upward. In addition, the Swivel part 105 under the influence of a walking spring 111, preferably designed as a rubber or plastic block, which tries to pivot the horizontal leg 105a of the swivel part 105 against the base plate 102. The pawl 108 is loaded by a closing spring 112 which is designed as a leg spring and which tries to press the latch 108c of the pawl 108 into the groove 104d of the swivel shell 104.

Der Aufbau und die Wirkungsweise einer solchen Skibindung sind an sich bekannt und bilden keinen Gegenstand der Erfindung.The structure and mode of operation of such a ski binding are known per se and form no subject of the invention.

An dem nach oben ragenden Schenkel 105b des Schwenkteiles 105 ist beidseitig je ein als Raste ausgebildeter Ansatz 105c₁, 105c₂ angeordnet. Am Kraftarm 108b der Klinke 108 sind an den beiden Enden einer Achse 108f zwei je einen Haken 120c,120d aufweisenden Riegel 120a,120b angelenkt, die durch zwei ebenfalls als Schenkelfedern ausgestaltete Verriegelungsfedern 121a,121b in die verriegelte Lage geschwenkt werden. Somit ist diese Ausgestaltung,bezogen auf die vertikale Längsmittelebene der Skibindung 101,symmetrisch ausgebildet. In Querrichtung gesehen ragt jeder Riegel 120a,120b über den Ansatz 105c₁, 105c₂ mit einem Abschnitt vor (s. Fig. 4). Die Unterseite eines jeden Ansatzes 105c₁, 105c₂ verläuft von vorne nach hinten schräg nach oben, um in der verrasteten Lage der Klinke 108, die der entriegelten Stellung der Skibindung 101 entspricht, einen sicheren Halt des Hakens 120c,120d jedes Riegels 120a,120b zu gewährleisten. Jedem vorragenden Abschnitt der beiden Riegel 120a,120b ist je ein an den Seitenwänden 104b₁, 104b₂ der Schwenkschale 104 angeordneter Nocken 104g₁, 104g₂ zugeordnet. Jeder dieser Nocken 104g₁, 104g₂ greift im entrasteten Zustand der Schwenkschale 104, d.h.,wenn die Rastnase 108c aus der Nut 104d des Quersteges 104c entfernt ist, an der Stirnseite 120e,120f des Hakens 120c,120d jedes Riegels 120a,120b an.On the upwardly projecting leg 105b of the pivoting member 105, a projection 105c₁, 105c₂ formed as a catch is arranged on both sides. On the power arm 108b of the pawl 108, two latches 120a, 120b, each with a hook 120c, 120d, are articulated at the two ends of an axle 108f, which are pivoted into the locked position by two locking springs 121a, 121b, also designed as leg springs. This configuration is thus symmetrical in relation to the vertical longitudinal center plane of the ski binding 101. Seen in the transverse direction, each latch 120a, 120b protrudes over the extension 105c₁, 105c₂ with a section (see FIG. 4). The underside of each approach 105c₁, 105c₂ extends obliquely upward from the front to the rear in order to ensure that the hook 120c, 120d of each latch 120a, 120b is securely held in the latched position of the pawl 108, which corresponds to the unlocked position of the ski binding 101 . Each projecting section of the two bolts 120a, 120b is assigned a cam 104g₁, 104g₂ arranged on the side walls 104b₁, 104b₂ of the swivel shell 104. Each of these cams 104g₁, 104g₂ engages in the unlocked state of the swivel shell 104, ie when the detent 108c is removed from the groove 104d of the crosspiece 104c, on the end face 120e, 120f of the hook 120c, 120d of each bolt 120a, 120b.

In der Fahrtstellung nehmen alle Elemente der Skibindung 101 die in Fig. 1 dargestellte Lage ein. Will der Skiläufer mit seinem Skischuh in die Skibindung 101 ein- bzw. aus dieser aussteigen, so wird der Kraftarm 108b der Klinke 108 mit dem Skistock nach unten gedrückt. Dabei rasten die Riegel 120a,120b an den Ansätzen 105c₁, 105c₂ des Schwenkteiles 105 ein (s.Fig.2). Soll nun diese Verriegelung gelöst werden, so wird die Schwenkschale 104 mittels der Öffnungsfeder 110 nach oben geschwenkt, und die Nocken 104g₁, 104g₂ der Schwenkschale 104 drücken über die Stirnflächen 120e,120f die Riegel 120a,120b von den Ansätzen 105c₁, 105c₂ zurück (vgl.Fig.3). Danach legt sich der Lastarm 108a der Klinke 108 unter dem Einfluß der Schließfeder 112 an den Quersteg 104c der Schwenkschale 104 an. Wird nun letztere mittels des Skischuhs niedergeschwenkt, so gleitet der Lastarm 108a solange entlang der Oberseite des Quersteges 104c, bis die Rastnase 108c der Klinke 108 wieder in die Nut 104d des Quersteges 104c einrastet.In the driving position, all elements of the ski binding 101 assume the position shown in FIG. 1. If the skier wants to get into or out of the ski binding 101 with his ski boot, the force arm 108b of the pawl 108 is pressed down with the ski stick. The latches 120a, 120b snap onto the lugs 105c₁, 105c₂ of the pivoting part 105 (see Fig. 2). If this locking is now to be released, the swivel shell 104 is pivoted upwards by means of the opening spring 110, and the cams 104g₁, 104g₂ of the swivel shell 104 press the latches 120a, 120b back over the end faces 120e, 120f from the shoulders 105c₁, 105c₂ (cf. Fig. 3). The load arm 108a of the pawl 108 then bears against the crossbar 104c of the swivel shell 104 under the influence of the closing spring 112. If the latter is now pivoted down by means of the ski boot, the load arm 108a slides along the top of the crossbar 104c until the catch 108c of the pawl 108 engages again in the groove 104d of the crossbar 104c.

In Verbindung mit den weiteren erfindungsgemäßen Ausgestaltungen werden anhand der folgenden Figuren nur diejenigen Bauelemente und Arbeitsweisen beschrieben, die sich von den jeweils vorangegangenen Ausführungen unterscheiden. Dabei wurden die gleichen Bauteile mit ansteigenden Hunderter-Bezugsziffern bezeichnet, und, falls vorhanden, in der Zeichnung selbst dann angegeben,wenn sie in der Beschreibung nicht erwähnt worden sind.In connection with the further refinements according to the invention, only those components and methods of operation which differ from the respective previous embodiments are described with reference to the following figures. The same components were designated with increasing hundreds of reference numerals and, if present, indicated in the drawing even if they were not mentioned in the description.

In Fig. 5 ist eine Variante zur ersten Ausführungsform in der Gebrauchsstellung der Skibindung 201 wiedergegeben. Im Gegensatz zum vorhergehenden Ausführungsbeispiel ist hier nur ein Riegel 220 vorgesehen, der symmetrisch zur vertikalen Längsmittelebene angeordnet, aus Federstahldraht hergestellt, in Seiten ansicht Z-förmig und in der Vorderansicht U-förmig ausgebildet ist (s. Fig. 5a). Dabei sind der Quersteg 220g des U und die anschließenden Abschnitte 220i, 220j der beiden Schenkel 220h₁, 220h₂ in dem Kraftarm 208b der Klinke 208 eingebettet. Die beiden freien, als Haken ausgebildeten, unteren Endabschnitte 220k, 220l der beiden Schenkel 220h₁, 220h₂ des Riegels 220 untergreifen in der verriegelten Stellung zwei Ansätze 205c₁, 205c₂ des Schwenkteiles 205.5 shows a variant of the first embodiment in reproduced the position of use of the ski binding 201. In contrast to the previous exemplary embodiment, only one latch 220 is provided here, which is arranged symmetrically to the vertical longitudinal median plane, made of spring steel wire, Z-shaped in side view and U-shaped in front view (see FIG. 5a). The crossbar 220g of the U and the subsequent sections 220i, 220j of the two legs 220h₁, 220h₂ are embedded in the power arm 208b of the pawl 208. The two free, hook-shaped, lower end sections 220k, 220l of the two legs 220h₁, 220h₂ of the latch 220 engage under the two positions 205c₁, 205c₂ of the pivoting part 205 in the locked position.

Das Lösen des Riegels 220 erfolgt, wie im vorhergehenden Beispiel beschrieben, mittels der Nocken 204g₁,204g₂der Schwenkschale 204, welche Nocken an den nach außen abgewinkelten Endabschnitten 220k, 220l der beiden Schenkel 220h₁, 220h₂ des Riegels 220 angreifen.The bolt 220 is released, as described in the previous example, by means of the cams 204g₁, 204g₂der the swivel shell 204, which engage the cams on the outwardly angled end sections 220k, 220l of the two legs 220h₁, 220h₂ of the bolt 220.

Die in den Fig. 6 und 7 dargestellte Skibindung 301 zeichnet sich dadurch aus, daß die beiden Riegel 320a,320b an den Kraftarm 308b der Klinke 308 zu beiden Seiten der vertikalen Längsmittelebene angesetzt sind. Dabei sind die beiden Riegel 320a, 320b aus dem Material der Klinke 308 hergestellt und als federnde Bauteile ausgestaltet.The ski binding 301 shown in FIGS. 6 and 7 is characterized in that the two bars 320a, 320b are attached to the power arm 308b of the pawl 308 on both sides of the vertical longitudinal center plane. The two bolts 320a, 320b are made from the material of the pawl 308 and are designed as resilient components.

Eine abgeänderte Skibindung 401 nach den Fig. 8 und 9 zeichnet sich dadurch aus, daß die Raste durch Rastnuten 403a, 403b der ersten Querachse 403, die gegen Verdrehen gesichert ist, gebildet wird. Die Rastnuten 403a, 403b sind in den beiden seitlichen Bereichen der Querachse 403 ausgespart und weisen je einen sektorförmigen Querschnitt auf. In die Rastnuten 403a,403b können die Haken 420c, 420d der beiden Riegel 420a,420b einrasten. Im vorliegenden Ausführungsbeispiel sind die Riegel 420a,420b ähnlich der Ausgestaltung nach den Fig. 6 und 7 dargestellt; sie können jedoch auch wie in den Fig. 1-4 ausgebildet sein.A modified ski binding 401 according to FIGS. 8 and 9 is characterized in that the detent is formed by locking grooves 403a, 403b of the first transverse axis 403, which is secured against rotation. The locking grooves 403a, 403b are in the two lateral ones Areas of the transverse axis 403 are recessed and each have a sector-shaped cross section. The hooks 420c, 420d of the two bolts 420a, 420b can snap into the locking grooves 403a, 403b. In the present exemplary embodiment, the bolts 420a, 420b are shown similar to the embodiment according to FIGS. 6 and 7; however, they can also be designed as in FIGS. 1-4.

Bei dem in den Fig. 10 bis 12 dargestellten Ausführungsbeispiel einer Skibindung 501 ist der Riegel 520 in Vorderansicht U-förmig und als ein aus Federstahldraht gefertigter Bügel ausgebildet (vgl. Fig. 11a) Dieser Riegel 520 ist mittels der oberen Endabschnitte 520i, 520j seiner beiden Schenkel 520h₁, 520h₂ im Kraftarm 508b der Klinke 508 befestigt. Diese Befestigung kann beispielsweise durch Umspritzung erfolgen. Im vorliegenden Falle sind in der Klinke 508 Nuten 508d, 508e ausgespart, in denen die oberen Endabschnitte 520i,520j der beiden Schenkel 520h₁, 520h₂ durch Preßsitz gehalten sind. Weiters sind die oberen Endabschnitte 520i, 520j mit Abwinkelungen 520m, 520n versehen, um einen sicheren Halt des Riegels 520 in der Klinke 508 zu gewährleisten. Im unteren Bereich sind die beiden Schenkel 520h₁, 520h₂ aus der Ebene des Riegels 520 abgewinkelt (520k, 520l) und tragen den Quersteg 520g des Riegels 520. Dabei bildet dieser Bereich den Haken 520c des Riegels 520.In the exemplary embodiment of a ski binding 501 shown in FIGS. 10 to 12, the bar 520 is U-shaped in front view and is designed as a bracket made of spring steel wire (see FIG. 11a). This bar 520 is its by means of the upper end sections 520i, 520j two legs 520h₁, 520h₂ in the power arm 508b of the pawl 508 attached. This attachment can be done, for example, by extrusion coating. In the present case 508d, 508e are recessed in the pawl, in which the upper end portions 520i, 520j of the two legs 520h₁, 520h₂ are held by an interference fit. Furthermore, the upper end sections 520i, 520j are provided with bends 520m, 520n in order to ensure that the bolt 520 is securely held in the pawl 508. In the lower area, the two legs 520h₁, 520h₂ are angled out of the plane of the bolt 520 (520k, 520l) and carry the crosspiece 520g of the bolt 520. This region forms the hook 520c of the bolt 520.

Im vorliegenden Ausführungsbeispiel weist der Quersteg 504c der Schwenkschale 504 eine von vorne nach hinten und von unten nach oben schräg verlaufende Ausnehmung 504h auf, deren Breite etwas größer als die Länge des Quersteges 520g des Riegels 520 ist. Dabei besitzt die obere Begrenzungswand der Ausnehmung 504h an ihrem vorderen Ende einen Ansatz 504f, an dem der Haken 520c des Riegels 520 in der verrasteten Lage zur Anlage kommt. Die untere Begrenzungswand der Ausnehmung 504h ist an ihrem vorderen Ende mit einem Nocken 504g versehen, durch welchen der Riegel 520 bei seinem Herausgleiten aus der Ausnehmung 504h unterstützt wird.In the present exemplary embodiment, the crosspiece 504c of the swivel shell 504 has a recess 504h which runs obliquely from the front to the rear and from the bottom to the top and whose width is somewhat larger than the length of the crosspiece 520g of the bolt 520. The upper boundary wall of the recess has 504h at its front end a shoulder 504f, on which the hook 520c of the bolt 520 comes to rest in the locked position. The lower boundary wall of the recess 504h is provided at its front end with a cam 504g, by means of which the bolt 520 is supported when it slides out of the recess 504h.

Beim Verschwenken der Klinke 508 mittels des Skistockes gleitet der Quersteg 520g des Riegels 520 in die Ausnehmung 504h im Quersteg 504c der Schwenkschale 504 (s. Fig.11), wodurch die Klinke 508 in der verschwenkten Lage festgehalten wird. Wird im Anschluß daran die Schwenkschale 504 vom Skischuh entgegen dem Uhrzeigersinn verschwenkt (s. Fig.12), so wird das Ende des Riegels 520 aus der Ausnehmung 504h des Quersteges 504c,unterstützt durch den Nocken 504g, herausgezogen, und die Klinke 508 kann sich im Uhrzeigersinn verschwenken (s. Fig. 12).When the pawl 508 is pivoted by means of the ski pole, the crosspiece 520g of the bolt 520 slides into the recess 504h in the crosspiece 504c of the swivel shell 504 (see FIG. 11), as a result of which the pawl 508 is held in the pivoted position. If the swivel shell 504 is subsequently pivoted counterclockwise by the ski boot (see FIG. 12), the end of the latch 520 is pulled out of the recess 504h of the crossbar 504c, supported by the cam 504g, and the pawl 508 can move swivel clockwise (see Fig. 12).

Bei der Skibindung 601 nach den Fig. 13 bis 15 ist der Riegel 620 als ein gekröpfter U-förmiger Federbügel ausgebildet,der gemeinsam mit der Schwenkschale 604 mit seinen Schenkeln 620h₁, 620h₂ auf der Querachse 603 schwenkbar gelagert ist. Diesem Riegel 620 ist eine Nase 608h, die von einer Nabe 608g der Klinke 608 vorragt, zugeordnet. Außerdem trägt die Schwenkschale 604 an der Innenseite jeder Seitenwand 604b₁, 604b₂ ein Paar von Vorsprüngen 604i, 604j, welche den Riegel 620 mittels dessen abgewinkelten unteren Endabschnitten 620k,620l federnd festhalten.13 to 15, the latch 620 is designed as a cranked U-shaped spring clip which is pivotally mounted on the transverse axis 603 together with the swivel shell 604 with its legs 620h 1, 620 h 2. This latch 620 is assigned a nose 608h, which projects from a hub 608g of the pawl 608. In addition, the swivel shell 604 carries on the inside of each side wall 604b₁, 604b₂ a pair of projections 604i, 604j which hold the latch 620 resiliently by means of its angled lower end sections 620k, 620l.

Wird die Schwenkschale 604 gegen die Skioberseite 600a hin verschwenkt, so wird der Riegel 620 gegen die Nabe 608g der Klinke 608 hin gedrückt (vgl. Fig. 13). Wird danach die Klinke 608 durch den Skistock entgegen dem Uhrzeigersinn verschwenkt, so rastet der Riegel 620 hinter der Nase 608h ein, und die Klinke 608 befindet sich in ihrer verriegelten (unwirksamen) Lage (s.Fig.14). Dabei befindet sich die Rastnase 608c der Klinke 608 in einem Abstand von der Oberseite des Quersteges 604c. Daher wird beim Hochschwenken der Schwenkschale 604 der Quersteg 604c unterhalb der Klinke 608 berührungsfrei verschwenkt. Dabei drückt die vordere Kante des Quersteges 604c der Schwenkschale 604 - welche Kante in ihrer Wirkung den Nocken nach dem ersten Ausführungsbeispiel entspricht - die nach hinten abgewinkelten Bereiche 620p, 620q des Bügels 620 nach vorne, so daß der Quersteg 620g sich von der Nase 608h abhebt und die Klinke 608 - beaufschlagt durch die Schließfeder- an der Rückwand des Quersteges 604c zur Anlage kommt (vgl. Fig. 15).If the swivel shell 604 is swiveled towards the top of the ski 600a, the latch 620 is pressed against the hub 608g of the pawl 608 (cf. FIG. 13). If the pawl 608 is then pivoted counterclockwise by the ski pole, the latch 620 engages behind the nose 608h, and the pawl 608 is in its locked (ineffective) position (see Fig. 14). The latch 608c of the pawl 608 is at a distance from the top of the crossbar 604c. Therefore, when the swivel shell 604 is swiveled up, the crosspiece 604c is swiveled without contact below the pawl 608. The front edge of the crosspiece 604c of the swivel shell 604 - which edge corresponds in effect to the cams according to the first exemplary embodiment - presses the regions 620p, 620q of the bracket 620 which are angled backwards, so that the crosspiece 620g lifts off from the nose 608h and the pawl 608 - acted upon by the closing spring - comes to bear against the rear wall of the crossbar 604c (cf. FIG. 15).

Beim Niederschwenken der Schwenkschale 604 durch den Skischuh gleitet die Rastnase 608c der Klinke 608 entlang der Oberseite des Quersteges 604c, derart, daß der Riegel 620 bzw. dessen Quersteg 620g von der Nase 608h immer in einem Abstand verbleibt, wodurch ein unerwünschtes Verriegeln vermieden wird. Dabei hebt der Quersteg 604c der Schwenkschale 604 den Riegel 620 von der Nase 608h ab. Danach kann die Klinke 608 in diejenige Stellung zurückkehren, in der sie die Schwenkschale 604 verriegelt.When the swivel shell 604 is swung down by the ski boot, the catch 608c of the pawl 608 slides along the top of the crosspiece 604c such that the latch 620 or its crosspiece 620g always remains at a distance from the nose 608h, thereby preventing undesired locking. The crossbar 604c of the swivel shell 604 lifts the latch 620 from the nose 608h. The pawl 608 can then return to the position in which it locks the swivel shell 604.

Von der zuletzt beschriebenen Skibindung unterscheidet sich die Skibindung 701 gemäß den Fig. 16 bis 18 dadurch, daß der Riegel 720 unmittelbar an der Schwenkschale 704 befestigt ist. Hiezu sind die abgewinkelten Enden 720m, 720n der beiden Schenkel 720h₁, 720h₂ in Bohrungen 704b₃, 704b₄ der Seitenwände 704b₁, 704b₂ der Schwenkschale 704 eingesetzt, und die beiden Schenkel 720h₁, 720h₂ sind mittels ihrer Abschnitte 720i, 720j in Nuten 704k, 7041 in den Seitenwänden 704b₁, 704b₂ festgehalten (vgl. insbes. Fig. 16b).The ski binding 701 according to FIGS. 16 to 18 differs from the ski binding described last in that the latch 720 is fastened directly to the swivel shell 704. For this purpose, the angled ends 720m, 720n of the two legs 720h₁, 720h₂ are inserted in bores 704b₃, 704b₄ of the side walls 704b₁, 704b₂ of the swivel shell 704, and the two legs 720h₁, 720h₂ are in grooves by means of their sections 720i, 720j 704k, 7041 held in the side walls 704b₁, 704b₂ (see in particular Fig. 16b).

Im übrigen entspricht die Arbeitsweise dieser Skibindung 701 der der zuvor beschriebenen Skibindung 601.Otherwise, the mode of operation of this ski binding 701 corresponds to that of the ski binding 601 described above.

Bei der Skibindung 801, die in den Fig. 19 bis 21 dargestellt ist, ist der Riegel 820 in seinem mittleren Bereich ähnlich einer Schenkelfeder mit einer Schlaufe 820r versehen. Durch diese Schlaufe 820r wird es möglich, daß der Riegel 820 normalerweise an der Nabe 808g anliegt und nur dann von der Nase 808h abgehoben wird, wenn die Schwenkschale 804 entgegen dem Uhrzeigersinn verschwenkt wird (s. Fig.21). Im übrigen entspricht die Arbeitsweise dieser Skibindung 801 der zuletzt beschriebenen Skibindung 701.In the case of the ski binding 801, which is shown in FIGS. 19 to 21, the bar 820 is provided with a loop 820r in its central region, similar to a leg spring. This loop 820r makes it possible for the latch 820 to normally abut the hub 808g and only be lifted off the nose 808h when the swivel shell 804 is swiveled counterclockwise (see FIG. 21). Otherwise, the mode of operation of this ski binding 801 corresponds to the ski binding 701 described last.

Eine weitere Skibindung 901 ist in den Fig. 22 bis 24 dargestellt. Diese zeichnet sich dadurch aus, daß der Riegel 920 als ein in Draufsicht U-förmiger Federbügel ausgebildet ist, dessen Schenkel 920h₁, 920h₂ mit ihren nach außen abgewinkelten Endbereichen 920m, 920n in den Seitenwänden 904b₁, 904b₂ der Schwenkschale 904 schwenkbar gelagert sind. Diesem Riegel 920 ist eine Raste zugeordnet, die in Form einer Einkerbung 908k an der Unterseite des Kraftarmes 908b der Klinke 908 ausgebildet ist. Dabei schließt die Innenseite der Einkerbung 908k mit der Unterseite des Klinke 908 einen spitzen Winkel α ein, wobei in diesem Falle die Innenseite der Einkerbung 908k nach dem Abschnitt einer archimedischen Spirale verläuft, deren Mittelpunkt in der Querachse 907 der Klinke 908 liegt. Der nach oben ragende Schenkel 905b des Schwenkteiles 905 besitzt einen als Quersteg ausgebildeten Ansatz 905c auf dem der Riegel 920 in der Fahrtstellung aufliegt (s.Fig.22). Wird die Klinke 908 mit dem Skistock entgegen dem Uhrzeigersinn verschwenkt, so gleitet der Quersteg 920g des Riegels 920 zunächst entlang der Unterseite der Klinke 908, wobei die beiden Schenkel 920h₁, 920h₂ des Riegels 920 auf der Oberseite des Ansatzes 905c des Schwenkteiles 905 aufliegen (vgl. Fig.23), wonach der Riegel 920 mit seinem Quersteg 920g in die Einkerbung 908k einrastet (vgl. Fig.24). Aus dieser verrasteten Stellung kann der Riegel 920 dadurch gelöst werden, daß die Schwenkschale 904 entgegen dem Uhrzeigersinn verschwenkt wird. Dabei gleitet der Quersteg 920g des Riegels 920 entlang der Oberseite der Einkerbung 908k aus dieser heraus, so daß die Klinke 908 unter dem Einfluß der Schließfeder in eine Lage gelangt, welche der in Fig.22 dargestellten Lage ähnlich ist.Another ski binding 901 is shown in FIGS. 22 to 24. This is characterized in that the bolt 920 is designed as a U-shaped spring clip in plan view, the legs 920h₁, 920h₂ with their outwardly angled end regions 920m, 920n in the side walls 904b₁, 904b₂ of the swivel shell 904 are pivotally mounted. This latch 920 is assigned a catch which is designed in the form of a notch 908k on the underside of the power arm 908b of the pawl 908. The inside of the notch 908k forms an acute angle α with the underside of the pawl 908, in which case the inside of the notch 908k runs according to the section of an Archimedean spiral whose center lies in the transverse axis 907 of the pawl 908. The upwardly projecting leg 905b of the swivel part 905 has a shoulder 905c designed as a crosspiece, on which the bolt 920 rests in the travel position (see FIG. 22). If the pawl 908 is swiveled counterclockwise with the ski pole, it slides Crossbar 920g of the bolt 920 initially along the underside of the pawl 908, the two legs 920h₁, 920h₂ of the bolt 920 resting on the top of the extension 905c of the pivoting part 905 (see FIG. 23), after which the bolt 920 with its crosspiece 920g in the notch 908k engages (see Fig. 24). From this locked position, the bolt 920 can be released in that the swivel shell 904 is pivoted counterclockwise. The cross piece 920g of the bolt 920 slides out of the notch 908k along the top thereof, so that the pawl 908 comes under the influence of the closing spring into a position which is similar to the position shown in FIG.

Die Skibindung 1001 nach den Fig. 25 bis 27 stellt im wesentlichen eine kinematische Umkehr zur Lösung nach den Fig. 1 bis 4 dar. Bei dieser Skibindung 1001 ist ein einziger auf einer Achse 1004m der Schwenkschale 1004 mittig gelagerter Riegel 1020 vorgesehen. Auch hier steht der Riegel 1020 unter dem Einfluß einer als Schenkelfeder ausgebildeten Verriegelungsfeder 1021, welche ihn entgegen dem Uhrzeigersinn zu schwenken sucht. An der Klinke 1008 ist ein Ansatz 1008j angeordnet, der dazu dient, die Klinke 1008 in der vom Skistock niedergedrückten Lage festzuhalten (s. Fig. 26). Weiters ist an der Klinke 1008 eine Steuerkurve 1008i ausgebildet, die dazu bestimmt ist, den Riegel 1020 von dem Ansatz 1008j gegen die Kraft der Verriegelungsfeder 1021 abzuheben, wenn die Schwenkschale 1004 entgegen dem Uhrzeigersinn verschwenkt wird. Durch die Schließfeder legt sich die Klinke 1008 mit ihrer Rastnase 1008c an die Rückseite des Quersteges 1004c der Schwenkschale 1004 an,und der Riegel 1020 kann in diejenige Stellung zurückkehren, in der er mit seiner Stirnseite 1020e an dem Ansatz 1008j anliegt (Fig. 27).The ski binding 1001 according to FIGS. 25 to 27 essentially represents a kinematic reversal to the solution according to FIGS. 1 to 4. With this ski binding 1001, a single latch 1020 is provided which is centrally mounted on an axis 1004m of the swivel shell 1004. Here, too, the bolt 1020 is under the influence of a locking spring 1021 which is designed as a leg spring and which attempts to pivot it counterclockwise. A lug 1008j is arranged on the pawl 1008 and serves to hold the pawl 1008 in the position depressed by the ski pole (see FIG. 26). Furthermore, a control cam 1008i is formed on the pawl 1008, which cam is designed to lift the bolt 1020 from the shoulder 1008j against the force of the locking spring 1021 when the swivel shell 1004 is pivoted counterclockwise. By means of the closing spring, the pawl 1008 rests with its catch 1008c on the rear of the crossbar 1004c of the swivel shell 1004, and the bolt 1020 can be inserted into it Return position in which it rests with its end face 1020e on the neck 1008j (Fig. 27).

Die Skibindung nach den Fig. 28 bis 30 unterscheidet sich von der zuletzt beschriebenen dadurch, daß der Riegel 1120 an der Querachse 1103 der Schwenkschale 1104 gelagert und mit seinem Haken 1120c in Richtung zur Schwenkschale 1104 hin gerichtet ist. Die Verriegelungsfeder 1121, die auf der Querachse 1103 sitzt, stützt sich mit einem Ende an der Schwenkschale 1104 und mit dem anderen Ende am Riegel 1120 ab. Die Arbeitsweise dieser Skibindung 1101 entspricht sinngemäß der des vorhergehenden Ausführungsbeispieles.The ski binding according to FIGS. 28 to 30 differs from the last described one in that the bolt 1120 is mounted on the transverse axis 1103 of the swivel shell 1104 and its hook 1120c is directed towards the swivel shell 1104. The locking spring 1121, which is seated on the transverse axis 1103, is supported at one end on the swivel shell 1104 and at the other end on the bolt 1120. The mode of operation of this ski binding 1101 corresponds analogously to that of the previous exemplary embodiment.

Die Skibindung 1201, welche in den Fig. 31 bis 35 dargestellt ist, weicht insofern von den bisher beschriebenen Ausführungsformen ab, als der Ansatz 1205f an einem in einer Bohrung 1205b₁ des Schenkels 1205b gelagerten und von einer Druckfeder 1205d beaufschlagten Schieber 1205e angeordnet ist. Der Riegel 1220, der an dem Lastarm 1208a der Klinke 1208 befestigt und starr ausgebildet ist, endet in einem Haken 1220c. Dieser Haken 1220c liegt in der Fahrtstellung mittig am Ansatz 1205f des Schiebers 1205e an (s. Fig. 31).The ski binding 1201, which is shown in FIGS. 31 to 35, differs from the previously described embodiments in that the attachment 1205f is arranged on a slide 1205e mounted in a bore 1205b₁ of the leg 1205b and acted upon by a compression spring 1205d. The latch 1220, which is attached to the load arm 1208a of the pawl 1208 and is rigid, ends in a hook 1220c. In the travel position, this hook 1220c is centered on the shoulder 1205f of the slide 1205e (see FIG. 31).

Wird die Klinke 1208 jedoch mit dem Skistock verschwenkt, so gelangt der Ansatz 1205f des Schiebers 1205e unter dem Einfluß der Druckfeder 1205d über den Haken 1220c und hält die Klinke 1208 in der verschwenkten Lage fest (s Fig. 32). Wird im Anschluß daran die Schwenkschale 1204 entgegen dem Uhrzeigersinn verschwenkt, so drücken die beiden Nocken 1204g der Schwenkschale 1204 den Schieber 1205e gegen die Kraft der Druckfeder 1205d zurück, und die Rastnase 1208c der Klinke 1208 legt sich unter dem Einfluß der Schließfeder an der Rückseite des Quersteges 1204c der Schwenkschale 1204 an (vgl. Fig. 33). Anschließend kann beim Niederdrücken der Schwenkschale 1204 die Klinke 1208 wieder in die Nut 1204d des Quersteges 1204c einrasten.However, if the pawl 1208 is pivoted with the ski pole, the extension 1205f of the slide 1205e passes under the influence of the compression spring 1205d via the hook 1220c and holds the pawl 1208 in the pivoted position (see FIG. 32). If the swivel shell 1204 is subsequently pivoted counterclockwise, the two cams 1204g of the swivel shell 1204 push the slide 1205e back against the force of the compression spring 1205d, and the catch 1208c of the pawl 1208 lies under the influence of the closing spring on the rear of the Cross bar 1204c of the swivel shell 1204 (see FIG. 33). Subsequently, the pawl 1208 can snap back into the groove 1204d of the cross bar 1204c when the swivel shell 1204 is pressed down.

Bei der Skibindung 1301, die in den Fig. 34 bis 36 dargestellt ist, ist der Riegel 1320 in den nach oben ragenden Schenkeln 1302a der Grundplatte 1302 mittels einer Querachse 1302f schwenkbar gelagert. Der dazugehörige Ansatz 1308j befindet sich bei dieser Ausführungsform am Kraftarm 1308b der Klinke 1308, ähnlich wie bei der Ausführung nach den Fig. 25 bis 30. Der Riegel 1320 steht unter dem Einfluß einer Verriegelungsfeder 1321, welche bestrebt ist, den Riegel 1320 gegen den Ansatz 1308j zu drücken. Außerdem trägt der Riegel 1320 einen in Richtung zur Schwenkschale 1304 hin gerichteten Vorsprung 1320s.In the case of the ski binding 1301, which is shown in FIGS. 34 to 36, the latch 1320 is pivotably mounted in the upwardly projecting legs 1302a of the base plate 1302 by means of a transverse axis 1302f. The associated extension 1308j is in this embodiment on the power arm 1308b of the pawl 1308, similar to the embodiment according to FIGS. 25 to 30. The bolt 1320 is under the influence of a locking spring 1321, which strives to lock the bolt 1320 against the extension To press 1308j. In addition, the latch 1320 carries a projection 1320s directed towards the swivel shell 1304.

Wird die Klinke 1308 aus der Fahrtstellung der Skibindung 1301 mit dem Skistock entgegen dem Uhrzeigersinn verschwenkt, so übergreift der Haken 1320c des Riegels 1320 den Ansatz 1308j, wodurch die Klinke 1308 in dieser Lage festgehalten wird (s. Fig. 35). Wird die Schwenkschale 1304 hochgeschwenkt, so kommt der Nokken 1304g bzw. dessen Begrenzungsfläche zur Anlage am Vorsprung 1320s des Riegels 1320, wodurch letzterer vom Ansatz 1308j weggedrückt wird (vgl. Fig.36). Unter dem Einfluß der Schließfeder 1312 legt sich anschließend der Lastarm 1308a der Klinke 1308 an die Rückseite des Quersteges 1304c der Schwenkschale 1304 an. Wird nun letztere niedergedrückt, so gleitet der Lastarm 1308a solange entlang der Oberseite des Quersteges 1304c, bis die Rastnase 1308c der Klinke 1308 in die Nut 1304d des Quersteges 1304c einrastet.If the pawl 1308 is pivoted counterclockwise from the driving position of the ski binding 1301 with the ski pole, the hook 1320c of the latch 1320 overlaps the shoulder 1308j, as a result of which the pawl 1308 is held in this position (see FIG. 35). If the swivel shell 1304 is swiveled up, the cam 1304g or its boundary surface comes to bear on the projection 1320s of the bolt 1320, as a result of which the latter is pushed away from the shoulder 1308j (see FIG. 36). Under the influence of the closing spring 1312, the load arm 1308a of the pawl 1308 then lies against the rear of the crossbar 1304c of the swivel shell 1304. If the latter is now depressed, the load arm 1308a slides along the top of the crossbar 1304c until the latching lug 1308c of the pawl 1308 engages in the groove 1304d of the crossbar 1304c.
