Description
Trainingsgerät für Skilanglauf. Die Erfindung betrifft ein Trainingsgerät für Skilanglauf, das ein Training unabhängig von Witterung und Jahreszeit ermöglicht.
Es ist gdkennzeichnet durch zwei endlose Zug organe, an denen mit Skibindungen verse hene Fussplatten befestigt. sind, welche Zug organe über eine Rutschkupplung durch einen Motor angetrieben werden, so aass, sich die Fussplatten in der Blickrichtung des Trainie renden bewegen, sowie durch zwei taeleskop- artig ausziehbare,
verschwenkbare iStöeke. Im folgenden wird an Hand einer Zeichnung eine Ausführungsform -beispielsweise beschrie ben.
Fig. 1 ist ein Schnitt nach der Linie I-1 der Feig. 2.
Fig.2 ist eine Draufsicht auf eine Aus führungsform des erfindungsgemässen Trai ningsgerätes.
Fig. 3 ist ein Detail des ausziehbaren Stockes, teilweise im Schnitt.
Fig. 4 ist ein Schnitt nach der Linie IV-IV der Fig. 3.
Fig. 5 ist ein Schnitt nach der Linie V-V der Fig. 3.
In einem Gestell 1 sind zwei Achsen 2 und 3 gelagert. Die Achse 2 ist über zwei Winkel zahnräder mit einem Repulsionsmotor 4 ver bunden; die Achse 3, ist in einem Schlitz gela gert und kann mit Hilfe der Muttern 6, und 6 verschoben werden, so dass der Abstand zwi schen den beiden Achsen. 2 und 3 verändert wird. Auf jeder Achse sitzen zwei Rollen 7 und 8 bzw. 9 und 10.
Die Rollen 7 und 8 sind'mt der Achse 2 starr verbunden,' wäh- ; rend die Rollen 9 und 10 frei drehen. End lose Stahlkabel 11 und. 12 sind über die Rollen:
7 und 9 bzw: 8 und 10 gespannt. Die Spärmung der Kabel wird mit Hilfe der Muttern 5 und 6 so,eingestellt, dass die Rol len 7 und 8 als Rutschkupplungen: wirken, das heisst dass die Kabel von den Rollen mit genommen werden, wenn nicht eine entspre chend grosse Kraft im entgegengesetzten Sinn auf sie .einwirkt. An jedem Kabel ist eine Fussplatte 13 bzw. 14 befestigt.
Diese Fuss platte -entspricht dem mittleren Teil eines Skis: Es handelt sich also um ein mit einer Skibindung versehenes Brett. Auf beiden Längsseiten des Gestelles sind 'Stöcke 15 und 16 angebracht. Diese sind; um Achsen 17 bzw. 18 verschwenkbar und bestehen aus zwei Tei- tèn, einem Zylinder 19 und einer 'Stange 20, -=die im Zylinder verschoben werden kann.
Unten an der Stange 20 ist .ein Kolben 21. befestigt. Die -Stange 20 und dieser Kolben 21 sind in einem weiteren Kolben 22 drehbar und , axial-verschiebbar. Der Kolben 2'2 passt in den Zylinder 19, so dass er in ihm noch auf- und abwärts geschoben werden kann. Er besitzt auf der Unterseite runde Löcher 23 und atü der obern Seite grössere Öffnunr gen 24. Die innere Mantelfläche ist gerippt.
Der Kolben: 21 besitzt Durchbohrungen 25 sowie einen federbelasteten !Stift 26, der die Drehungdes Kolbens 21 relativ zum Kolben 22 erschwert. Liegen de Löcher 23 und die Bohrungen 25 übereinander, so kann beim Auf- und Abwärtsstossen der Stangen 20 die Luft ungehindert durchtreten; werden die Löcher jedoch durch gegenseitiges Verdrehen.
der beiden Kolbenteile gegeneinander ver setzt, so wird die Luft beim Aufwärtsziehen des Kolbens 21 durehdiesen hindurchströmen können- da zwischen ihm -und den Löchern 23 im Boden des Kolbens 22ein Zwischenraum besteht. Da die Löcher 24 bedeutend grösser sind, werden die Bohrungen 25 vom Deckel des Kolbens 22 nicht verdeckt. Beim Abwärts stossen wird nun der -Kolben: 2,1 auf den Boden des Kolbens 22 gestossen, so dass dort kein Zwischenraum mehr besteht. Da die Boh rungen 215 nur noch zum Teil über den Lö chern 23 liegen, wird der Querschnitt für ,den Luftdurchgang kleiner, was eine Brem sung zur Folge hat.
Das Gerät wird folgendermassen benützt: Der Trainierende steht auf- den: Fussplatten und befestigt diese an den Schuhen wie ge- wöhnliche Skis. Dann lässt er den Repulsions- motor mit. der gewünschten Schnelligkeit lau fen, so dass die Stahlkabel die Fussplatten nach vorn ziehen. Der Trainierende beginnt nun zum Beispiel damit, dass er den linken Fuss nach vorn ziehen lässt. Den rechten be lasteten Fuss muss er nach hinten stossen, was einen Arbeitsaufwand benötigt, da die Rolle 8 das Kabel 12 mitnehmen möchte und nun unter ihm gleitet.
Beim nächsten Schritt wird umgekehrt der linke Fuss belastet und unter Arbeitsaufwand nach hinten geschoben, während der rechte unbelastet durch den motorischen Antrieb nach vorn gezogen wird. Diese Bewegungen entsprechen den wirklichen Verhältnissen beim Lauf im :Schnee, nur mit dem Unterschied, .dass der Läufer hier am selben Ort bleibt. Zur Unterstützung des Laufens dienen auch hier, wie im Schnee, die Stöcke.
Wegen der oben beschriebenen Ventile sind sie leicht ausziehbar, während ein grösserer Kraftaufwand benötigt wird, um sie einzustossen, was ebenfalls den Ver hältnissen im Schnee entspricht. Durch ein Drehen der Handgriffe ist der Widerstand veränderlich, so dass verschiedene Schneever hältnisse imitiert werden können. Auch die Tourenzahl des Motors sowie der Schlupf zwischen den Stahlkabeln und den Rollen ist veränderlich, so .dass das .ganze Trainingsgerät leicht den jeweiligen Bedürfnissen angepasst werden kann.
Es wäre auch möglich, am Gestell Stützen oder variable Füsse anzubringen, um e, schief zu stellen, damit das Laufen nicht nur im ebenen, sondern auch im steigenden und fallenden Gelände trainiert werden kann.
Training device for cross-country skiing. The invention relates to a training device for cross-country skiing that enables training regardless of weather and season.
It is characterized by two endless pulling organs to which foot plates with ski bindings are attached. are which traction organs are driven by a motor via a slip clutch, so that the footplates move in the direction of view of the trainee, as well as two telescopic extendable,
swiveling iStöeke. In the following, an embodiment is described, for example, using a drawing.
Fig. 1 is a section along line I-1 of Fig. 2.
2 is a top view of an embodiment of the training device according to the invention.
Fig. 3 is a detail of the extendable stick, partly in section.
FIG. 4 is a section along the line IV-IV of FIG. 3.
FIG. 5 is a section on the line V-V of FIG. 3.
Two axes 2 and 3 are mounted in a frame 1. The axis 2 is connected via two angle gears with a repulsion motor 4 a related party; the axis 3 is gela in a slot and can be moved with the help of nuts 6 and 6, so that the distance between tween the two axes. 2 and 3 is changed. There are two rollers 7 and 8 or 9 and 10 on each axis.
The rollers 7 and 8 are rigidly connected to the axle 2, wäh-; rend the rollers 9 and 10 rotate freely. Endless steel cables 11 and. 12 are about the roles:
7 and 9 or: 8 and 10 cocked. The heating of the cables is adjusted with the help of nuts 5 and 6 so that the Rol len 7 and 8 act as slip clutches, that is, the cables are taken from the rollers, if not a correspondingly large force in the opposite sense acts on them. A footplate 13 or 14 is attached to each cable.
This footplate corresponds to the middle part of a ski: it is therefore a board with a ski binding. On both long sides of the frame 'sticks 15 and 16 are attached. These are; pivotable about axes 17 or 18 and consist of two parts, a cylinder 19 and a rod 20 = which can be moved in the cylinder.
A piston 21 is attached to the bottom of the rod 20. The rod 20 and this piston 21 can be rotated and axially displaced in a further piston 22. The piston 2'2 fits into the cylinder 19 so that it can still be pushed up and down in it. It has round holes 23 on the underside and larger openings 24 on the upper side. The inner surface is ribbed.
The piston: 21 has through bores 25 and a spring-loaded pin 26, which makes the rotation of the piston 21 relative to the piston 22 difficult. If the holes 23 and the bores 25 are one above the other, the air can pass through unhindered when the rods 20 are pushed up and down; however, the holes are twisted together.
of the two piston parts is set against one another, the air will be able to flow through it when the piston 21 is pulled upwards - since there is a gap between it and the holes 23 in the bottom of the piston 22. Since the holes 24 are significantly larger, the bores 25 are not covered by the cover of the piston 22. When pushing downwards, the piston: 2, 1 is pushed onto the bottom of the piston 22 so that there is no longer any space there. Since the bores 215 are only partially above the holes 23, the cross section for the air passage is smaller, which has a brake result.
The device is used as follows: The trainee stands on: footplates and attaches them to the shoes like ordinary skis. Then he leaves the repulsion motor with. run at the desired speed so that the steel cables pull the footplates forward. The trainee now starts, for example, by letting his left foot pull forward. He has to push the right loaded foot backwards, which requires a lot of work because the roller 8 wants to take the cable 12 with it and now slides under it.
In the next step, the left foot is loaded and pushed backwards with effort, while the right foot is pulled forward by the motor drive without any load. These movements correspond to the real conditions when running in: snow, with the only difference that the runner stays in the same place. As in the snow, the sticks are used to support walking.
Because of the valves described above, they are easy to pull out, while greater effort is required to push them in, which also corresponds to the conditions in the snow. By turning the handles, the resistance can be changed so that different snow conditions can be imitated. The number of revolutions of the motor and the slip between the steel cables and the rollers can also be changed, so that the entire training device can be easily adapted to the respective needs.
It would also be possible to attach supports or variable feet to the frame in order to put it at an angle, so that running can be trained not only on flat terrain, but also on ascending and falling terrain.
