Abstract

The invention relates to a climbing and braking support (1) for skiers, having a baseplate for mounting on top of the ski and a pivot bearing (2) arranged thereon in which two unilateral pivot levers (3) are pivotably mounted so as to be lockable in a pivoted position. It also has a double-sided lever (6) arranged in a second pivot bearing on the baseplate so as to be pivotable. One free end of this lever is capable of engagement with a locking lug (10) in a locking notch (19). Both levers have spring elements to restore them in active connection. In order to achieve a strong design and to eliminate the risk of injury, it is proposed that the two one-sided pivot levers be fixedly connected to each other via at least one intermediate piece (7) which has a flat surface on an upper side, at least one intermediate piece having a locking notch (19) for the locking lug and at least one intermediate piece (7) having a stop surface for bearing on the baseplate (21) in the initial position of the one-sided pivot lever, the two-sided pivot lever having a further flat surface (8) on one upper side. <IMAGE>

Description

Die Erfindung betrifft eine Steig- und Bremshilfe für Skier, mit einer Bodenplatte zur oberseitigen Montage auf einem Ski und einer darauf angeordneten Schwenklagerung, in der zwei einseitige Schwenkhebel schwenkbar und in einer Schwenkstellung einrastbar gelagert sind, sowie mit einem auf der Bodenplatte in einer weiteren Schwenklagerung schwenkbar angeordneten zweiseitigen Hebel, dessen eines freies Ende mit einer Rastnase in eine Rastkerbe einrastbar ist, wobei beide Hebel mit Federelementen zu deren Rückstellung in Wirkverbindung stehen.The invention relates to a climbing and braking aid for skis, with a base plate for top mounting on a ski and a swivel bearing arranged thereon, in which two one-sided swivel levers are pivotally mounted and can be locked in a swivel position, and with one on the base plate in a further swivel bearing pivotably arranged two-sided lever, one free end of which can be latched into a latching notch with a latching lug, both levers being operatively connected to spring elements for their resetting.

Eine Steig- und Bremshilfe für Skier der eingangs beschriebenen Art ist bekannt geworden durch das US-Patent Nr. 3,724,867. Bei dieser Steig- und Bremshilfe können die beiden einseitigen Schwenkhebel durch ein mit ihnen verbundenes, in Ausgangsstellung senkrecht zum Ski stehendes, stabförmiges Hebelelement durch Druck auf die an dem freien Ende des Hebelelementes befindliche Vertiefung bzw. durch Umlegen des Hebelelementes herabgeklappt werden, wobei durch einen speziellen Mechanismus die einseitigen Hebel zunächst seitlich auseinander geführt und dann über die Außenränder des Skies heraggeklappt werden. In dieser Stellung rastet der zweiseitige Hebel mit seiner Rastnase in die Rastkerbe des Hebelelementes ein und fixiert damit die beiden einseitigen Schwenkhebel in einer Brems- oder Steigstellung. Um die beiden einseitigen Schwenkhebel wieder in Ausgangsstellung zurückzuklappen muß zunächst auf das Hebelelement Druck ausgeübt werden, um die Rastnase zu entlasten, wodurch gleichzeitig durch Druck auf das der Rastnase gegenüberliegende Ende des zweiseitigen Hebels bzw. auf die hier befindliche Vertiefung die Rastnase aus der Rastkerbe herausgeführt werden kann und damit die zweiseitigen Schwenkhebel und der zweiseitige Hebel durch die Federelemente in Ausgangsstellung gebracht werden. Der spezielle Mechanismus übernimmt bei diesem Vorgang das Zusammenführen der beiden einseitigen Schwenkhebel oberhalb des Skies.A climbing and braking aid for skis of the type described in the introduction has become known from US Pat. No. 3,724,867. With this climbing and braking aid, the two one-sided swivel levers can be folded down by a rod-shaped lever element connected to them, which is perpendicular to the ski in the starting position, by pressure on the depression located at the free end of the lever element or by flipping the lever element, with one special mechanism, the one-sided levers are first moved sideways and then folded over the outer edges of the ski. In this position, the two-sided lever engages with its latching lug in the latching notch of the lever element and thus fixes the two one-sided pivot levers in a braking or climbing position. In order to fold the two one-sided swivel levers back into the starting position, pressure must first be exerted on the lever element in order to relieve the latching lug, whereby at the same time the latching lug is led out of the latching notch by pressure on the end of the two-sided lever opposite the latching lug or on the depression located here can be and thus the two-sided swivel lever and the two-sided Lever are brought into the starting position by the spring elements. The special mechanism takes care of bringing together the two single-sided swivel levers above the ski.

Da die bekannte Steig- und Bremshilfe in der Regel nur unter Zuhilfenahme der Skistöcke bedient werden kann, ist das etwa senkrecht zum Ski stehende stabförmige Hebelelement mit der relativ kleinen Vertiefung als Angriffsfläche für den Skistock sehr unpraktisch und damit schwer bedienbar. Darüber hinaus bedeutet das senkrecht zum Ski stehende Hebelelement sowie die in Ausgangsstellung hochstehenden einseitigen Hebel für den Skifahrer bei einem Skiunfall ein erhöhtes Verletzungsrisiko. Weiterhin wirkt sich sehr nachteilig aus, daß zur Rückstellung der einseitigen Schwenkhebel beide Skistöcke gleichzeitig zum Bedienen der Steig- und Bremshilfe eingesetzt werden müssen, wodurch z. B. am Hang ein sicherer Stand des Skifahrers nicht mehr gewährleistet ist. Ein weiterer Nachteil besteht darin, daß das Federelement zur Rückstellung des zweiseitigen Hebels unter der Vertiefung des zweiseitigen Hebels zwischen der Oberseite des Skies und der Unterseite des zweiseitigen Hebels angebracht ist. Hierdurch kann z. B. beim Entfernen von Schnee oder Eis der bzw. das sich zwischen dem zweiseitigen Hebel und dem Ski festgesetzt hat und dadurch die Funktion des zweiseitigen Hebels stört, das Federelement beschädigt oder herausgerissen werden. Weiterhin nachteilig wirkt sich die direkte Montage des Federelementes auf dem Ski aus, da hierdurch in den Ski eine zusätzliche Bohrung eingebracht werden muß. Dadurch, daß die bekannte Steig- und Bremshilfe aus sehr vielen Einzelteilen besteht, ist diese in der Herstellung teuer und darüber hinaus sehr wartungs- und reparaturanfällig.Since the known climbing and braking aid can generally only be operated with the help of the ski poles, the rod-shaped lever element, which is approximately perpendicular to the ski and has a relatively small depression as a contact surface for the ski pole, is very impractical and therefore difficult to operate. In addition, the lever element that is perpendicular to the ski and the one-sided lever that stands up in the starting position mean an increased risk of injury to the skier in the event of a skiing accident. Furthermore, it is very disadvantageous that both ski poles must be used simultaneously to operate the climbing and braking aid to reset the one-sided swivel lever. B. on a slope, a safe position of the skier is no longer guaranteed. Another disadvantage is that the spring element for resetting the two-sided lever is attached under the recess of the two-sided lever between the top of the ski and the underside of the two-sided lever. As a result, z. B. when removing snow or ice or which has settled between the two-sided lever and the ski and thereby interferes with the function of the two-sided lever, the spring element is damaged or torn out. A further disadvantage is the direct mounting of the spring element on the ski, since this means that an additional hole has to be drilled in the ski. Because the known climbing and braking aid consists of a large number of individual parts, it is expensive to manufacture and, moreover, very susceptible to maintenance and repairs.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Steig- und Bremshilfe für Skier vorzuschlagen, die leicht zu bedienen ist und die Verletzungsgefahr bei einem Unfall minimiert sowie in der Herstellung preiswert und darüber hinaus robust und wartungsfreundlich ist. Diese Aufgabe ist ausgehend von einer Steig- und Bremshilfe für Skier der eingangs beschriebenen Art dadurch gelöst, daß die beiden einseitigen Schwenkhebel über mindestens ein Zwischenstück, daß auf einer Oberseite eine ebene Fläche aufweist, fest miteinander verbunden sind, wobei mindestens ein Zwischenstück eine Rastkerbe für die Rastnase und mindestens ein Zwischenstück eine Anschlagfläche zur Anlage an der Bodenplatte in Ausgangsstellung der einseitigen Schwenkhebel aufweist, wobei der zweiseitige Hebel auf einer Oberseite eine weitere ebene Fläche aufweist. Eine derartige Steig- und Bremshilfe kann aus sehr wenigen Teilen preiswert hergestellt werden. Sie ist darüber hinaus robust und sehr wartungsfreundlich. Weiterhin wird durch ihre flache Bauweise die Verletzungsgefahr bei einem Unfall minimiert.Starting from this prior art, the object of the invention to propose a climbing and braking aid for skis that is easy to use and minimizes the risk of injury in the event of an accident, is inexpensive to manufacture and, furthermore, is robust and easy to maintain. This object is achieved on the basis of a climbing and braking aid for skis of the type described in the introduction in that the two one-sided pivot levers are firmly connected to one another via at least one intermediate piece, which has a flat surface on an upper side, at least one intermediate piece having a notch for the locking lug and at least one intermediate piece has a stop surface for bearing against the base plate in the starting position of the one-sided pivot levers, the two-sided lever having a further flat surface on an upper side. Such a climbing and braking aid can be inexpensively manufactured from very few parts. It is also robust and very easy to maintain. Furthermore, the flat design minimizes the risk of injury in the event of an accident.

Eine Ausgestaltung der Erfindung sieht vor, daß die beiden einseitigen Schwenkhebel mit mindestens einem Zwischenstück als Baueinheit ausgeführt sind. Hierdurch wird nicht nur die Zahl der Bauteile der Steig- und Bremshilfe verringert, sondern auch die Stabilität verbessert.An embodiment of the invention provides that the two one-sided swivel levers are designed with at least one intermediate piece as a structural unit. This not only reduces the number of components of the climbing and braking aid, but also improves the stability.

Nach einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, daß das Zwischenstück gegen die Fahrtrichtung versetzt zur Schwenklagerung auf seiner Oberseite eine Druckmulde aufweist. Der Skistock kann hier mit seiner Sitze zum Herabklappen der einseitigen Schwenkhebel sehr leicht angesetzt werden.According to a further embodiment of the invention, it is proposed that the intermediate piece, offset from the direction of travel, have a pressure trough on its upper side for the pivot bearing. The ski pole can be attached very easily with its seats for folding down the one-sided swivel levers.

Wiederum nach einer Ausgestaltung der Erfindung wird vorgeschlagen, daß der zweiseitige Hebel in Fahrtrichtung versetzt zur weiteren Schwenklagerung auf seiner Oberseite eine weitere Druckmulde aufweist. Hierdurch kann ebenfalls ein Skistock, zur Rückstellung der Steig- und Bremshilfe, auf dem zweiseitigen Hebel sehr leicht angesetzt werden.Again according to an embodiment of the invention it is proposed that the two-sided lever offset in the direction of travel for further pivoting on its upper side has a further pressure trough. This can also a ski pole, for resetting the climbing and braking aid, can be very easily attached to the two-sided lever.

Darüber hinaus wird nach einer Ausgestaltung der Erfindung vorgeschlagen, daß das Zwischenstück mindestens eine weitere Rastkerbe aufweist. Hierdurch ist es möglich je nach Schneebeschaffenheit und Hangneigung eine entsprechend günstige Angriffstiefe der einseitigen Schwenkhebel zu wählen.In addition, it is proposed according to an embodiment of the invention that the intermediate piece has at least one further notch. This makes it possible to choose a suitable depth of attack for the one-sided swivel lever depending on the snow conditions and slope.

Weiterhin wird nach einer Ausgestaltung der Erfindung vorgeschlagen, daß die Rastnase eine Anlagefläche sowie jede Rastkerbe eine Rastfläche aufweist, die in Raststellung aneinander anliegen, wobei deren Anlagewinkel etwa einer Senkrechten auf einer Geraden, die durch eine Achse der weiteren Schwenklagerung und durch eine untere Spitze der Rastnase verläuft, entspricht. Der so gewählte Anlagewinkel ermöglicht ein sicheres Einrasten der heruntergeklappten einseitigen Schwenkhebel. Darüber hinaus kann durch bloßen Druck auf die Druckmulde des zweiseitigen Schwenkhebels die Rastnase aus der Rastkerbe gelöst werden, wodurch über die Federelemente die einseitigen Schwenkhebel in Ausgangsstellung zurückgeführt werden.Furthermore, it is proposed according to an embodiment of the invention that the latching lug has a contact surface and each latching notch has a latching surface which abuts one another in the latching position, the bearing angle of which is approximately perpendicular to a straight line which is defined by an axis of the further pivot bearing and by a lower tip of the Latch runs, corresponds. The system angle selected in this way enables the one-sided swivel lever to be securely locked into place. In addition, the locking lug can be released from the locking notch by simply pressing on the pressure trough of the two-sided pivoting lever, as a result of which the one-sided pivoting levers are returned to the starting position via the spring elements.

Wiederum eine Ausgestaltung der Erfindung schlägt vor, daß die beiden einseitigen Schwenkhebel an ihren freien Enden jeweils einen zur Fahrtrichtung gekrümmten Bereich aufweisen. Hierdurch können die einseitigen Schwenkhebel ähnlich wie Krallen im Schnee oder Eis greifen.Another embodiment of the invention proposes that the two one-sided pivot levers each have at their free ends a region curved toward the direction of travel. This allows the one-sided swivel levers to grip similar to claws in snow or ice.

Ferner wird nach einer Ausgestaltung der Erfindung vorgeschlagen, daß die beiden einseitigen Schwenkhebel in ihren gekrümmten Bereichen mindestens zur Fahrtrichtung eine Querverzahnung aufweisen. Hierdurch wird die Griffigkeit der einseitigen Schwenkhebel in ihren gekrümmten Bereichen verbessert bei einer Anordnung als Bremse.Furthermore, it is proposed according to an embodiment of the invention that the two one-sided swivel levers have transverse teeth in their curved regions at least to the direction of travel. This improves the grip of the one-sided pivot levers in their curved areas when arranged as a brake.

Fernerhin wird nach einer Ausgestaltung der Erfindung vorgeschlagen, daß die Bodenplatte einstückig ist. Auch hierdurch wird die Zahl der Bauteile der Steig- und Bremshilfe verringert und die Stabilität erhöht. Weiterhin schlägt eine Ausgestaltung der Erfindung vor, daß der zweiseitige Hebel zur Rückstellung eine an der weiteren Schwenklagerung angeordnete Spiralfeder aufweist. Hierdurch kann Schnee oder Eis, das sich zwischen Bodenplatte und dem der Rastnase abgewandten Teil des zweiseitigen Schwenkhebels abgesetzt hat und dadurch den zweiseitigen Schwenkhebel in seiner Funktion stört, leicht entfernt werden, ohne dabei die Spiralfeder zu beschädigen. Weiterhin kann hierdurch eine zusätzliche Bohrung auf dem Ski entfallen.Furthermore, it is proposed according to an embodiment of the invention that the base plate is in one piece. This also reduces the number of components of the climbing and braking aid and increases stability. Furthermore, an embodiment of the invention proposes that the two-sided lever for resetting has a spiral spring arranged on the further pivot bearing. As a result, snow or ice, which has settled between the base plate and the part of the double-sided pivoting lever facing away from the locking lug and thereby interferes with the function of the double-sided pivoting lever, can be easily removed without damaging the coil spring. Furthermore, an additional hole on the ski can be omitted.

Des weiteren wird nach einer Ausgestaltung der Erfindung vorgeschlagen, daß die beiden einseitigen Hebel so angeordnet sind, daß mindestens die gekrümmten Bereiche in Ausgangsstellung mit einem geringen Abstand oberhalb einer Oberkante des Skies angeordnet sind. Hierdurch wird erreicht, daß in Ausgangsstellung die beiden einseitigen Schwenkhebel ein Gleiten des Skies nicht beeinträchtigen.Furthermore, it is proposed according to an embodiment of the invention that the two one-sided levers are arranged such that at least the curved regions are arranged in the starting position with a small distance above an upper edge of the ski. This ensures that the two one-sided swivel levers do not interfere with sliding of the ski in the starting position.

Schließlich wird nach einer Ausgestaltung der Erfindung vorgeschlagen, daß die Rastnase des zweiseitigen Hebels eine ebene Unterseite aufweist, die in Ausgangsstellung auf der ebenen Fläche des Zwischenstücks aufliegt. Hierdurch kann der zweiseitige Hebel sehr flach gebaut und auf das Zwischenstück aufgelegt werden, wodurch ebenfalls eine Verletzungsgefahr bei einem Unfall verringert wird.Finally, it is proposed according to one embodiment of the invention that the latching lug of the two-sided lever has a flat underside which rests on the flat surface of the intermediate piece in the starting position. As a result, the two-sided lever can be built very flat and placed on the intermediate piece, which also reduces the risk of injury in the event of an accident.

Die Erfindung soll nun anhand der beigefügten Zeichnungen näher erläutert werden.The invention will now be explained in more detail with reference to the accompanying drawings.

In Figur 1 ist die erfindungsgemäße Steig- und Bremshilfe schematisch in der Seitenansicht dargestellt. Die Steig- und Bremshilfe ist mit der Bodenplatte 21 auf einen Ski 27 nach Belieben vor oder hinter der Bindung montiert. Jeder einseitige Schwenkhebel 3, 3' befindet sich in Ausgangsstellung und liegt dabei mit der Anschlagfläche 30 auf der Bodenplatte 21 auf. Der gekrümmte Bereich 24 mit der in Fahrtrichtung 23 zeigenden Querverzahnung 11 befindet sich in dieser Ausgangsstellung oberhalb der Oberkante 26 des Skis 27. Die Rastnase 10 des zweiseitigen Hebels 6 liegt dabei mit ihrer ebenen Unterseite 28 auf der ebenen Fläche 4 (Figuren 3 und 4) des gezeigten Zwischenstücks 7 auf. Soll nun der einseitige Schwenkhebel 3, 3' z. B. zum Bremsen des Skis an Hängen herabgeklappt werden, so genügt es, den Skistock mit der Spitze auf die ebene Fläche 4 aufzusetzen und bis in die Druckmulde 9' zu führen. Der einseitige Schwenkhebel 3, 3' läßt sich nun unter leichtem Druck um die Schwenklagerung 3 nach unten klappen. Um den Schwenkhebel 3, 3' wieder in die Ausgangsstellung zurückzubringen genügt es, einen Skistock mit der Spitze auf der weiteren ebenen Fläche 8 des zweiseitigen Hebels 6 aufzusetzen und ihn in die Druckmulde 9 zu führen und so durch Druck mit dem Skistock den zweiseitigen Hebel 8 um die weitere Schwenkachse 5 zu kippen, wobei sich die Rastnase 10 aus der Rastkerbe 13 bzw. aus der weiteren Rastkerbe 19 löst. Dies ist wegen der besonderen Winkellage der Anlageflächen bzw. Rastflächen 12, 14, 20 möglich.In Figure 1, the climbing and braking aid according to the invention is shown schematically in side view. The climbing and braking aid is mounted with the base plate 21 on a ski 27 in front of or behind the binding as desired. Each one-sided pivot lever 3, 3 'is in the starting position and lies with the stop surface 30 on the base plate 21. The curved region 24 with the transverse toothing 11 pointing in the direction of travel 23 is in this starting position above the upper edge 26 of the ski 27. The latching nose 10 of the two-sided lever 6 lies with its flat underside 28 on the flat surface 4 (FIGS. 3 and 4). of the intermediate piece 7 shown. If the one-sided pivot lever 3, 3 'z. B. can be folded down to brake the ski on slopes, it is sufficient to place the ski pole with the tip on the flat surface 4 and to lead into the pressure trough 9 '. The one-sided pivot lever 3, 3 'can now be folded down around the pivot bearing 3 under slight pressure. In order to bring the swivel lever 3, 3 'back into the starting position, it is sufficient to place a ski pole with the tip on the further flat surface 8 of the two-sided lever 6 and to guide it into the pressure trough 9 and thus to press the two-sided lever 8 with the ski pole about the further pivot axis 5 tilt, the detent 10 detaches from the notch 13 or from the further notch 19. This is possible because of the special angular position of the contact surfaces or locking surfaces 12, 14, 20.

Figur 2 zeigt die Steig- und Bremshilfe 1 schematisch dargestellt in der Seitenansicht, wobei der einseitige Schwenkhebel 3 sich in einer Raststellung befindet. Die Rastnase 10 ist dabei in die in Figur 1 erkennbare Rastkerbe 13 eingerastet, wobei die in Figur 1 gezeigte Anlagefläche 12 der Rastnase 10 an der Rastfläche 14 der Rastkerbe 13 anliegt. Wie aus Figur 2 ersichtlich, entspricht der Anlagewinkel der Rastfläche 14 und der Anlagefläche 12 etwa einer Senkrechten 15 auf einer Geraden 16, die durch die Achse 17 der weiteren Schwenklagerung 5 und durch die untere Spitze 18 der Rastnase 10 verläuft. Durch einen so gewählten Anlagewinkel kann die Rastnase unter leichtem Druck auf die Druckmulde 9 des zweiseitigen Hebels 6 aus der Rastkerbe 13 herausgeführt werden, ohne daß dabei mit einem zweiten Skistock Druck auf das in Figur 4 gezeigte Zwischenstück ausgeübt und damit die Rastnase entlastet werden muß. Hierdurch kann ein Skifahrer z. B. an Hängen den zweiten Skistock zu seiner Standsicherung einsetzen. Nachdem die Rastnase 10 aus der in Figur 1 dargestellten Rastkerbe 13 gelöst wurde, wird der einseitige Schwenkhebel 3 durch eine auf der Schwenklagerung 2 angeordnete, in Figur 1 und 2 aus Gründen der Übersichtlichkeit nicht dargestellte Spiralfeder automatisch wieder in Ausgangsstellung zurückgeführt. Die Anschlagfläche 30 legt sich dabei wieder an die Bodenplatte 21. Durch eine ebenfalls nicht dargestellte, auf der weiteren Schwenklagerung 5 angeordnete Spiralfeder wird die ebene Unterseite der Rastnase 10, wie in Figur 1 dargestellt, wieder auf der ebenen Fläche 4 des Zwischenstücks 7 abgelegt. Dadurch, daß die Spiralfeder auch am zweiseitigen Hebel 6 auf der weiteren Schwenklagerung 5 angeordnet ist, kann Schnee, der sich zwischen dem zweiseitigen Hebel 6 und der Bodenplatte 21 festgesetzt hat und damit die Funktion des zweiseitigen Hebels 6 beeinträchtigt, ohne Beschädigung der Spiralfeder mit einem spitzen Gegenstand, beispielsweise mit dem Skistock, entfernt werden. Durch die insgesamt flache Bauweise der Steig- und Bremshilfe 1 wird bei Skiunfällen eine Verletzungsgefahr des Skifahrers vermieden.Figure 2 shows the climbing and braking aid 1 shown schematically in side view, the one-sided pivot lever 3 is in a locking position. The locking lug 10 is snapped into the locking notch 13 which can be seen in FIG. 1, the contact surface 12 of the locking lug 10 shown in FIG. 1 abutting the locking surface 14 of the locking notch 13. As can be seen from FIG. 2, the contact angle of the locking surface 14 and the contact surface 12 corresponds approximately to a vertical line 15 on a straight line 16 which runs through the axis 17 of the further pivot bearing 5 and through the lower tip 18 of the locking lug 10. By means of a system angle selected in this way, the latching lug can be guided out of the latching notch 13 under slight pressure on the pressure trough 9 of the two-sided lever 6, without pressure being exerted on the intermediate piece shown in FIG. 4 with a second ski pole and thus the latching lug must be relieved. This allows a skier, for. B. use the second ski pole on slopes to secure its position. After the locking lug 10 has been released from the locking notch 13 shown in FIG. 1, the one-sided pivot lever 3 is automatically returned to the starting position by a spiral spring arranged on the pivot bearing 2 and not shown in FIGS. 1 and 2 for reasons of clarity. The stop surface 30 lies against the base plate 21 again. A flat spring on the further pivot bearing 5, which is also not shown, is used to place the flat underside of the latch 10, as shown in FIG. 1, on the flat surface 4 of the intermediate piece 7. The fact that the coil spring is also arranged on the two-sided lever 6 on the further pivot bearing 5, snow that has settled between the two-sided lever 6 and the base plate 21 and thus the function of the two-sided Lever 6 impaired, without damaging the coil spring with a pointed object, such as the ski stick, to be removed. The overall flat design of the climbing and braking aid 1 avoids the risk of injury to the skier in skiing accidents.

In Figur 3 ist ebenfalls eine Steig- und Bremshilfe 1 schematisch in der Seitenansicht dargestellt, jedoch in einer anderen Raststellung. Je nach Schneeverhältnissen oder nach Steilheit der Hänge kann der einseitige Schwenkhebel 3, 3' in unterschiedliche Raststellungen eingerastet werden, wobei der gekrümmte Bereich 24 des einseitigen Schwenkhebels 3 mit seiner Querverzahnung 11 unterschiedlich tief in den Schnee eingreift. Natürlich können auch mehr als in den Figuren 1 bis 3 dargestellte Rastkerben 13, 19 an dem Zwischenstück 7 vorgesehen sein. Vorteilhaft läßt sich der einseitige Schwenkhebel 3 aus jeder Raststellung mit nur einem Skistock durch leichen Druck mit der Skistockspitze auf die Druckmulde 9 des zweiseitigen Hebels 6 in die Ausgangsstellung zurückführen. Deutlich ist aus den Figuren 1 bis 3 die flache Bauweise der Steig- und Bremshilfe 1 zu erkennen.In Figure 3, a climbing and braking aid 1 is also shown schematically in the side view, but in a different locking position. Depending on the snow conditions or the steepness of the slopes, the one-sided pivot lever 3, 3 'can be snapped into different detent positions, the curved region 24 of the one-sided pivot lever 3 engaging in the snow at different depths with its transverse toothing 11. Of course, more than the notches 13, 19 shown in FIGS. 1 to 3 can also be provided on the intermediate piece 7. Advantageously, the one-sided swivel lever 3 can be returned to the starting position with only one ski pole by light pressure with the tip of the ski pole onto the pressure trough 9 of the two-sided lever 6. The flat design of the climbing and braking aid 1 can be clearly seen from FIGS. 1 to 3.

Figur 4 zeigt die erfindungsgemäße Steig- und Bremshilfe 1 schematisch dargestellt in der Draufsicht. Die beiden Schwenkhebel 3, 3' sind mit dem Zwischenstück 7 als eine Baueinheit ausgeführt. Die einseitigen Schwenkhebel 3, 3' sind bei montierter Steig- und Bremshilfe 1 so angeordnet, daß sie den Ski 27 mit ihren Innenkanten 29, 29' seitlich leicht überragen. Durch die ebene Fläche 4 des Zwischenstücks 7 und die weitere ebene Fläche 8 des zweiseitigen Schwenkhebels 6 wird noch einmal deutlich, wie leicht hier eine Skistockspitze angesetzt werden und in die relativ großen Druckmulden 9, 9' eingeführt werden kann. Dadurch, daß die einseitigen Schwenkhebel 3, 3' in Ausgangsstellung schon so angeordnet sind, daß sie den Ski mit ihren Innenkanten seitlich überragen, kann auf eine komplizierte, störungs- und verschließanfällige Mechanik, die die beiden einseitgen Schwenkhebel 3, 3' beim Herunterklappen auseinanderführt, bzw. beim Zurückführen in die Ausgangsstellung wieder zusammenführt, verzichtet werden.Die gleichen beschriebenen Stellungen wirken jedoch nicht nur als Bremshilfe sondern auch als Steighilfe. Die nach unten geschwänkten einseitigen Hebel 3, 3' verhindern ein Zurücklaufen des Ski und bilden damit eine sichere Steighilfe, deren Wirksamkeit durch die verschienenen Schwenkhebellagen der einseitigen Hebel 3, 3' angepaßt werden kann.Figure 4 shows the climbing and braking aid 1 according to the invention shown schematically in plan view. The two pivot levers 3, 3 'are designed with the intermediate piece 7 as a structural unit. The one-sided swivel levers 3, 3 'are arranged with the climbing and braking aid 1 mounted so that they slightly protrude laterally from the ski 27 with their inner edges 29, 29'. The flat surface 4 of the intermediate piece 7 and the further flat surface 8 of the two-sided pivot lever 6 once again show how easily a ski pole tip can be attached here and can be inserted into the relatively large pressure recesses 9, 9 '. The fact that the one-sided swivel levers 3, 3 'are already arranged in the starting position so that they laterally protrude the inner edges of the ski can result in a complicated mechanism which is susceptible to malfunction and susceptibility to wear and tear and which the two sided Swing lever 3, 3 'apart when folding down, or merging when returning to the starting position, the same positions described not only act as a braking aid but also as a climbing aid. The downward-swinging levers 3, 3 'prevent the ski from running back and thus form a safe climbing aid, the effectiveness of which can be adjusted by the various pivot lever positions of the one-sided levers 3, 3'.

Mit der Erfindung wird somit eine Steig- und Bremshilfe für Skier vorgeschlagen, die sehr einfach aus wenigen Bauteilen herstellt werden kann und dadurch eine sehr robuste und störungsunanfällige Bauweise erlaubt. Darüber hinaus schützt die flache Bauweise der Steig- und Bremshilfe den Skifahrer bei Skiunfällen vor Verletzungen. Ein weiterer Vorteil der vorgeschlagenen Steig- und Bremshilfe ist dadurch gegeben, daß die zum Bremsen oder Steigen abgeklappten einseitigen Schwenkhebel in unterschiedlichen Raststellungen eingerastet werden und durch leichten Druck auf einen zweiseitigen Hebel mit nur einem Skistock in Ausgangsstellung zurückgebracht werden können.The invention thus proposes a climbing and braking aid for skis that can be manufactured very easily from a few components and thus allows a very robust and failure-prone construction. In addition, the flat construction of the climbing and braking aid protects the skier from injuries in skiing accidents. Another advantage of the proposed climbing and braking aid is given by the fact that the one-sided swivel levers folded down for braking or climbing are locked in different latching positions and can be brought back to the starting position by light pressure on a double-sided lever with only one ski pole.
