Description

Die Erfindung betrifft einen Behinderten-Ski mit einer auf einem Mono-Ski abgestützten Sitzwanne mit einem Sitzbereich.The invention relates to a handicapped ski with a seat pan supported on a mono-ski with a seating area.

Ein solches Sportgerät ist aus der US-PS-4 310 169 bekannt. Der Sitzbereich ist relativ kurz, so daß die Beine eines Behinderten nicht geschützt sind.Such a sports device is known from US Pat. No. 4,310,169. The seating area is relatively short, so that the legs of a disabled person are not protected.

Aufgabe der vorliegenden Erfindung ist es eine Möglichkeit zu skifahrerischer Betätigung für Personen zu schaffen, die hinsichtlich der Bewegungsfähigkeit ihrer Beine behindert sind. Es soll also ein möglichst einfaches und sicheres Gerät geschaffen werden, mit dem auch Behinderte, z. B. Querschnittsgelähmte, Skifahren können.The object of the present invention is to create a possibility for skiing activity for persons who are disabled with regard to the mobility of their legs. The aim is to create a device that is as simple and safe as possible, with which disabled people, eg. B. paraplegic, skiing.

Diese Aufgabe wird durch einer Behinderten-Ski gemäß Patentanspruch 1 gelöst. Die Erfindung betrifft ferner verschiedene vorteilhafte Weiterbildungen.This object is achieved by a ski for the disabled according to claim 1. The invention further relates to various advantageous developments.

Es hat sich gezeigt, daß sogar mit einem solchen Behinderten-Ski oder Skigerät Querschnittsgelähmte jeden Skihang - sei es Buckel-Piste, sei es Tiefschnee - herunterfahren können. Es ist nur eine Einübungszeit von wenigen Tagen erforderlich. Die Steuerung erfolgt durch Gewichtsverlagerung, ggf. mit Hilfe sog. Krückenski, d. h. kleiner Skier, die beweglich oder fest an kurzen Krücken angebracht sind und aus der Sitzposition in der Sitzwanne benutzt werden.It has been shown that even with such a handicapped ski or ski device, paraplegics can descend every ski slope - be it hump slope or deep snow. It only takes a few days to practice. The control takes place by shifting weight, if necessary with the help of so-called Krückenski, d. H. small skis that can be moved or attached to short crutches and used from the sitting position in the seat pan.

Auf nur einem Mono-Ski 1 ist, in der Längsebene gelenkig, über eine Stütze 2 eine Sitzwanne 3 angebracht. Diese Sitzwanne 3 besteht aus einem Unterteil 4 und einem Oberteil 5, wobei der Oberteil 5 zum Ein- und Aussteigen abnehmbar ist und mittels Verschlußbügeln 6 auf dem Unterteil 4 arretiert werden kann. Der hintere Teil der Sitzwanne 3 ist der Sitzbereich 7 mit einer Seitenlehne 31 und einer Rücklehne 33, die etwa bis zu den Achselhöhlen einer Person, die in der Sitzwanne 3 sitzt, hochgezogen sind. Der Sitzbereich 7 ist über einen Stoßdämpfer 9 auf dem Mono-Ski 1 abgestützt. Die Verbindung von Stütze 2 und Mono-Ski 1 ist gelenkig ausgebildet.On only one mono-ski 1, a seat pan 3 is attached in an articulated manner in the longitudinal plane via a support 2. This seat pan 3 consists of a lower part 4 and an upper part 5, the upper part 5 being removable for getting in and out and being able to be locked on the lower part 4 by means of locking brackets 6. The rear part of the seat pan 3 is the seating area 7 with a side back 31 and a back rest 33 which are pulled up to the armpits of a person sitting in the seat pan 3. The seating area 7 is supported on the mono-ski 1 via a shock absorber 9. The connection of support 2 and mono-ski 1 is articulated.

Zur Benutzung setzt sich eine Person (vgl. Fig. 1) in die Sitzwanne 3 hinein. Um dies zu erleichtern und den Halt zu verbessern, ist der Boden der Sitzwanne 3 nicht waagerecht ausgebildet, sondern vielmehr derart geformt, wie es dem Sitz auf einer ebenen Fläche mit etwas angezogenen Knieen entspricht, also mit einem etwas erhöhten Kniekehlen-Abstützbereich 10. Entsprechend ist der Oberteil 5 an Stelle 11 höher ausgebildet. Der Fuß-Bereich 12 nimmt die Füße auf, wobei eine entsprechende Vergrößerung des Oberteils bei 13 die Fußspitzen und gegebenenfalls noch eine Decke oder sonstige Dinge, die mitgenommen werden müssen oder sollen, aufnehmen kann. Der Oberteil 13 weist nach vorne hin und seitlich schräge Abflachungen 34 auf, um im Falle eines Sturzes das Eingraben des Gerätes im Schnee durch eine ansonsten an dieser Stelle gegebene Ecke oder Kante zu vermeiden.For use, a person sits down in the seat pan 3 (see FIG. 1). In order to facilitate this and to improve the hold, the bottom of the seat pan 3 is not designed horizontally, but rather is shaped in such a way that it corresponds to the seat on a flat surface with the knees slightly raised, that is to say with a slightly raised back of the knee support area 10 the upper part 5 is formed higher at point 11. The foot region 12 picks up the feet, with a corresponding enlargement of the upper part at 13 being able to accommodate the toes and possibly a blanket or other things that have to or should be taken along. The upper part 13 has flats 34 which are inclined towards the front and to the side, in order to prevent the device from being buried in the snow in the event of a fall by an otherwise given corner or edge at this point.

Nach Abnehmen des Oberteils 5 kann sich eine Person, die Querschnittsgelähmt ist, in die Sitzwanne 3 hineinsetzen (siehe Fig. 1). Der Oberteil wird danach mittels der Verschlußbügel 6 wieder am Unterteil 4 arretiert. Durch Gewichtsverlagerung, durch "Krücken-Ski" unterstützt, kann eine Person auf diese Art und Weise skifahren.After removing the upper part 5, a person who is paraplegic can sit down in the seat pan 3 (see FIG. 1). The upper part is then locked again by means of the locking bracket 6 on the lower part 4. By shifting weight, supported by "crutch skis", a person can ski in this way.

Der Behinderten-Ski weist einen Schlepp- und Stützbügel 15 auf (vgl. Fig. 2). Dieser Schlepp-und Stützbügel 15 besteht aus zwei Stützteilen 16 zu beiden Seiten der Sitzwanne 3. Beide sind über Querbügel 17 und 18 miteinander verbunden. Dieser gesamte durch die zwei Stützteile 16 und die zwei Querbügel 17 und 18 gebildete Schlepp- und Stützbügel 15 ist an der Sitzwanne beidseitig derselben bei 19 angelenkt und wird durch eine Feder 20, die zwischen Stütze 2 und Querbügel 17 angebracht ist, in die gezeigte Position gezogen, in der die Enden 21 der Stützteile 16 auf den Boden drücken und so den Behinderten-Ski abstützen, der demgemäß ohne Unterstützung durch den Behinderten selbst auf dem Boden stehen kann. Zum Fahren werden gegen die Kraft der Feder 20 die hinteren unteren Enden 21 der Stützteile 16 nach oben gezogen (vgl. Fig. 1 und die strichpunktiert eingezeichnete Position in Fig. 2). Dabei wird der Schlepp- und Stützbügel 15 in dieser Position durch ein Verschlußelement 22 gehalten, in das der Querbügei 18 "einschnappt", und das durch einen einfachen Griff wieder gelöst werden kann.The disabled ski has a towing and support bracket 15 (see FIG. 2). This drag and support bracket 15 consists of two support parts 16 on both sides of the seat pan 3. Both are connected to one another via cross brackets 17 and 18. This entire tow and support bracket 15 formed by the two support parts 16 and the two crossbars 17 and 18 is articulated on the seat pan on both sides of the same at 19 and is in the position shown by a spring 20 which is attached between the support 2 and the crossbar 17 pulled, in which the ends 21 of the support parts 16 press on the floor and thus support the disabled ski, which can accordingly stand on the floor without support from the disabled. For driving, the rear lower ends 21 of the support parts 16 are pulled upward against the force of the spring 20 (cf. FIG. 1 and the position shown in broken lines in FIG. 2). The towing and support bracket 15 is held in this position by a closure element 22 into which the cross bracket 18 "snaps" and which can be released again with a simple grip.

Zum Einhängen eines Schleppbügels T eines Schlepplifts ist an den oberen Enden der Stützteile 16 ein Schleppbügelhalter 40 vorgesehen (vgl. Fig. 3,4), der durch einen Gurt 41 gebildet wird. Er weist ein Schloß 42 auf, das wie bei einem Anschnallgurt in einem Auto, durch Druck auf Knopf 43 leicht geöffnet werden kann. Er wird durch zwei Stäbe 16', 16" aus Federstahl in der gespannten Lage gehalten.To attach a drag bar T of a drag lift, a drag bar holder 40 is provided at the upper ends of the support parts 16 (cf. FIGS. 3, 4), which is formed by a belt 41. It has a lock 42, the like a seat belt in a car, can be easily opened by pressing button 43. It is held in the tensioned position by two rods 16 ', 16 "made of spring steel.

Alternativ kann man einen Schleppbügel-Halter 23 (Fig. 5) so ausbilden, daß man zwei Haken 23', 23" an den oberen Enden der Stützteile 16 anbringt. In diese Haken 23', 23" wird der Schleppbügel T eingelegt.Alternatively, a tow bar holder 23 (FIG. 5) can be designed in such a way that two hooks 23 ', 23 "are attached to the upper ends of the support parts 16. The tow bar T is inserted into these hooks 23', 23".

Gemäß Fig. 6 kann ein Schleppbügelhalter 44 auch direkt an der Sitzwanne 3 angebracht sein. Er wird gebildet durch Gurt 45 und Schloß 46, das durch Druck auf Knopf 47 öffnenbar ist.6, a tow bar holder 44 can also be attached directly to the seat pan 3. It is formed by belt 45 and lock 46, which can be opened by pressing button 47.

Bei dem Ausführungsbeispiel des Behinderten-Skis nach Fig. 7 wird die Sitzwanne 3 auf dem Mono-Ski 1 durch eine bandartig ausgebildete Feder 50 aus Stahl oder zwecks Gewichtsersparnis aus glas- oder kohlefaserverstärktem Kunststoff gehalten. Diese ist an der Sitzwanne 3 im Bereich der Rückenlehne 33 und etwa mittig am Unterteil 4 bei 51 und 52 angelenkt.In the embodiment of the disabled ski according to FIG. 7, the seat pan 3 is held on the mono-ski 1 by a spring 50 made of steel or made of glass or carbon fiber reinforced plastic in order to save weight. This is articulated on the seat pan 3 in the area of the backrest 33 and approximately centrally on the lower part 4 at 51 and 52.

Alternativ zu den gezeigten Aufhängemöglichkeiten kann man auch Fig. 1 so abwandeln, daß der Stoßdämpfer durch eine C-förmige Feder gebildet wird.As an alternative to the suspension options shown, Fig. 1 can also be modified so that the shock absorber is formed by a C-shaped spring.

Die Sitzwanne 3 ist aus kohle- oder glasfaserverstärktem Kunststoff aufpralldämpfend hergestellt.The seat pan 3 is made of carbon or glass fiber reinforced plastic to absorb impact.

Beim in den Fig. 8 und 9 dargestellten Ausführungsbeispiel ist die Feder 50 kreisbogenabschnittförmig mit einem Ende um eine zur Längsachse senkrechte Achse schwenkbar am Boden des Unterteils 4 etwa mittig angelenkt. Das freie Ende ist in einer Führung im gerundeten Übergang zwischen Boden und Rückenlehne 33 des Bodenteils 4 in einer Führung 56 längsverschiebbar geführt, wobei die Führungsfläche verschleißfest und gut gleitend ausgebildet ist.In the embodiment shown in FIGS. 8 and 9, the spring 50 is articulated in the shape of a circular arc with one end pivotable approximately in the middle of the bottom of the lower part 4 about an axis perpendicular to the longitudinal axis. The free end is guided in a guide in the rounded transition between the floor and the backrest 33 of the bottom part 4 in a guide 56, the guide surface being designed to be wear-resistant and smoothly sliding.

Der Mono-Ski 1 ist über 2 in achsialem Abstand voneinader angeordneten Vibrationsdämpfer 49 mit der Feder 50 einstellbar verbunden, wobei der Abstand der Vibrationsdämpfer 49 und deren Längsanordung auf dem Mono-Ski 1 durch eine auf diesem vorgesehene Verstellschiene 48 in weiten Grenzen verstellbar ist zur Beeinflussung der Gleiteigenschaften bei unterschiedlichem Körpergewicht aber auch unterschiedlichem Fahrkönnen des versehrten Sporttreibenden.The mono-ski 1 is connected to the spring 50 in an adjustable manner via 2 vibration dampers 49 arranged at an axial distance from one another, the distance between the vibration dampers 49 and their longitudinal arrangement on the mono-ski 1 being adjustable within wide limits by means of an adjustment rail 48 provided thereon Influencing the sliding properties with different body weights but also different driving skills of the injured sportsperson.

Am oberen Ende des Stützteils 16 ist beidseitig ein bogenförmiger Schleppbügelhalter 23 über eine leicht lösbare Steckverbindung aufgesteckt. Eingebaut in ihm ist die durch den Knopf 47 über einen Bowdenzug oder ein nicht dargestelltes Gestange betätigbare Auslösevorrichtung für den Schleppbügelhalter 23 mit seinen Haken 23' und 23".At the upper end of the support part 16, an arcuate drag bracket 23 is attached to both sides via an easily detachable plug connection. Installed in it is the release device for the tow bar holder 23 with its hooks 23 'and 23 "which can be actuated by the button 47 via a Bowden cable or a rod (not shown).

Wie in Fig. 9 ersichtlich können diese Haken 23', 23" zum Ausklinken des Schleppbügels 7 in Fahrtrichtung weggeschwenkt werden (strichpunktiert) und zur Vermeidung von Verletzungen während der Abfahrt entgegen der Fahrtrichtung weggeklappt, gegebenenfalls sogar im Schleppbügelhalter 23 wenigstens teilweise versenkt werden.As can be seen in FIG. 9, these hooks 23 ', 23 "can be swiveled away in the direction of travel to release the tow bar 7 (dash-dotted lines) and folded away against the direction of travel to avoid injuries during the descent, possibly even at least partially sunk in the tow bar holder 23.

Zur weiteren Herabsetzung der Verletzungsgefahr ist im Oberteil 5 eine Aufnahmerille 39 für den Schleppbügelhalter 23 vorgesehen in der dieser in seiner Abfahrtstellung eintaucht. In der Start- und Wartestellung stehen die unteren Enden des Stützteils 16 durch die Schwenkwirkung der Feder 20 auf dem Untergrund auf und halten den Behinderten-Ski in senkrechter Lage (Fig. 8) während in der Abfahrtstellung auch die unteren Enden des Stützteils 16 am Unterteil 4 strömunggünstig und unfallsicher anliegen.To further reduce the risk of injury, a receiving groove 39 is provided in the upper part 5 for the tow bar holder 23 in which the latter dips in its downward position. In the start and waiting position, the lower ends of the support part 16 stand up on the ground due to the pivoting action of the spring 20 and hold the disabled ski in a vertical position (FIG. 8), while in the down position, the lower ends of the support part 16 on the lower part 4 flow-tight and safe against accidents.

Um das Eindringen von Schnee und Wasser in die Sitzwanne 3 zu erschweren, ist der obere Rand des Oberteils 5 mit einem Wasserabweiser 25 versehen.In order to make it more difficult for snow and water to penetrate into the seat pan 3, the upper edge of the upper part 5 is provided with a water deflector 25.

Beim in Fig. 10 dargestellten weiteren Ausführungsbeispiel ist die Feder 50 kürzer ausgebildet und stützt sich nicht mit ihrem freien Ende am Unterteil 4 ab. Dafür ist am hinteren Ende des Unterteils 4 zwischen diesem und dem Mono-Ski 1 ein Stoßdämpfer 9 und eine Zusatzfeder 50' angeordnet.In the further exemplary embodiment shown in FIG. 10, the spring 50 is of shorter design and is not supported with its free end on the lower part 4. For this purpose, a shock absorber 9 and an additional spring 50 'are arranged at the rear end of the lower part 4 between it and the mono-ski 1.

In Fig. 11 ist der Stoßdämpfer 49 im Querschnitt dargestellt. Er weist 2 U-förmige Schienen 49' und 49" auf, mit unterschiedlicher Breite, deren Öffnungen einander zugekehrt sind. Zwischen den Basisteilen und den Schenkeln ist jeweils eine Elastomer- oder Gummi-Brücke 57, 58, 58' vorgesehen, dabei ist zwischen den Schenkeln der Schiene 49" und der Brücke 57 mindestens teilweise ein Abstand um so in Längsrichtung eine großere Steifigkeit und Dämpfung zu erreichen gegenüber einem Kippen um die Querachse.11, the shock absorber 49 is shown in cross section. It has two U-shaped rails 49 'and 49 ", with different widths, the openings of which face each other. An elastomer or rubber bridge 57, 58, 58' is provided between the base parts and the legs, with a the legs of the rail 49 "and the bridge 57 at least partially a distance in order to achieve greater rigidity and damping in the longitudinal direction compared to tilting about the transverse axis.

In den Fig. 12 und 13 ist die Möglichkeit des Umbaus eines Behinderten-Ski 1 in ein Langlaufgerät dargestellt. Auf der Unterseite des Unterteils 4 sind quer und im Abstand 2 Stellschienen 53, 54 angeodnet in die über Stützen 2', 2" zwei Skier 1', 1" im Abstand voneinader einstellbar montiert werden können anstelle eines Mono-Skis 1.
