Abstract

Parts of the sports appliance, which are pulled when tension members in the form of pulley cables (4) fixed to a shaft (1) are operated, affect a braking mechanism so that a rotor is braked harder, the stronger the pull. The tension members run through a deflector coupled to the braking mechanism. The appliance has a firm or flexible handle (7). The rotor consists of a shaft (1) to which are fixed one or more brake discs (2) on which brake blocks (8) work fixed to a brake rod linkage system (9). The rotor and brake are contained in a housing (5). USE/ADVANTAGE - The braking resistance produced by the sports appts. can be continuously changed by the person training.

Description

Die Erfindung betrifft ein als tragbares Handgerät konzipiertes Sportgerät, das zum Trainieren an feststehenden Gegenständen oder an Körper des Trainierenden oder einer anderen Person gehalten ist und bei dem an zwei Zuggliedern in wechselseitig-gegenläufiger Bewegung gezogen wird. Die Zugglieder wirken dabei auf einen im Gerät befindlichen abgebremsten Rotor ein und bringen diesen zum Rotieren mit wechselnder Drehrichtung. Dabei wird der Rotor um so stärker abgebremst, je kräftiger an den Zuggliedern gezogen wird.The invention relates to a portable handheld device Conceived sports equipment that can be used for training on fixed Objects or on the body of the exerciser or one is held by another person and with two tension members is drawn in reciprocal movement. The tension members act on one in the device decelerated rotor and bring it to rotate changing direction of rotation. The rotor becomes stronger braked, the harder the pull members are pulled.

Unter P 42 22 484.5 wurde beim Deutschen Patentamt ein ähnliches Gerät angemeldet, bei dem jedoch die Bremskraft jeweils fest eingestellt werden muß. Das hat den Nachteil, daß man, um die Bremskraft zu verstellen, jedesmal das Training unterbrechen muß. Das ist insbesonders dann sehr störend, wenn Intervalltraining betrieben wird, d. h., mal stärker und mal weniger stark an den Zuggliedern gezogen wird.P 42 22 484.5 was filed with the German Patent Office Similar device registered, but with the braking force must always be set. This has the disadvantage that in order to adjust the braking force, that every time Interrupt training. That is especially so disruptive when interval training is practiced, d. h. times is pulled harder and sometimes less strongly on the tension members.

Der Erfindung lag demgemäß die Aufgabe zugrunde, ein derartiges Sportgerät so auszustatten, daß der darin erzeugte Bremswiderstand von dem Trainierenden stufenlos verändert werden kann, ohne daß deswegen das Training unterbrochen werden muß. The invention was accordingly based on the object to equip such sports equipment so that the in it generated braking resistance continuously by the trainee can be changed without changing the training must be interrupted.  

Diese Aufgabe wurde erfindungsgemäß dadurch gelöst, daß Teile des Gerätes; die beim Trainieren unter Zug stehen, derart auf die Rotorbremse einwirken, daß deren Bremskraft umso größer ist und der Rotor um so stärker abgebremst wird, je kräftiger an den Zuggliedern gezogen wird.According to the invention, this object was achieved by that parts of the device; who are under train while training, act on the rotor brake such that its braking force the bigger and the more the rotor is braked, the harder the pull members are pulled.

In einer Ausbildung der Erfindung besteht der in einem Gehäuse 5 befindliche Rotor aus einer drehbar gelagerten Welle 1 und einer darauf befestigten Bremsscheibe 2 und zwei beidseits davon angebrachten Wickelkörpern 3 mit Wickelnuten. Die zwei Zugglieder bestehen aus Zugseilen 4, die gegenläufig auf die Wickelkörper aufgewickelt sind.In one embodiment of the invention, the rotor located in a housing 5 consists of a rotatably mounted shaft 1 and a brake disc 2 fastened thereon and two winding bodies 3 with winding grooves attached on both sides thereof. The two tension members consist of tension cables 4 , which are wound in opposite directions on the winding body.

Auf die Bremsscheibe 2 wirken zwei Bremsklötze 8 ein, die an einem als Bremszange 9 ausgebildeten Bremsgestänge befestigt sind. An der Bremszange 9 ist eine Halteschlaufe 7, an der das Gerät beim Trainieren gehalten oder befestigt wird, derart angebracht, daß sich die Bremszange 9 zusammenzieht und dabei die Bremsklötze 8 um so stärker gegen die Bremsscheibe 2 drückt, je größer die auf die Halteschlaufe 7 einwirkenden Zugkräfte sind.Two brake pads 8 act on the brake disc 2 and are attached to a brake linkage designed as a brake caliper 9 . On the brake caliper 9 , a hand strap 7 , to which the device is held or fastened during training, is attached in such a way that the brake caliper 9 contracts and thereby presses the brake pads 8 against the brake disc 2 , the greater the force on the hand strap 7 acting tensile forces.

Der mit der Erfindung erzielte Vorteil liegt darin, daß die Bremskraft und damit der Widerstand, den die Zugglieder dem Trainierenden entgegensetzen, stufenlos variiert werden kann, ohne daß deswegen das Training unterbrochen werden muß.The advantage achieved with the invention is that that the braking force and thus the resistance that the Opposing tension members to the exerciser, continuously can be varied without training must be interrupted.

Eine Ausbildung der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is in the drawing shown and is described in more detail below.

Fig. 1 und 2 zeigen Schnitte durch ein solches Gerät. Fig. 1 and 2 show sections through such a device.

Der Rotor besteht aus der Welle 1, der Bremsscheibe 2 und den Wickelkörpern 3 mit den Wickelnuten. Wickelkörper 3 und Bremsscheibe 2 sind derart mit­ einander verbunden, daß sie sich nicht gegeneinander verdrehen können. Die Zugseile 4 sind an den Wickel­ körpern 3 oder der Bremsscheibe 2 befestigt und in den Wickelnuten gegenläufig aufgewickelt. The rotor consists of the shaft 1 , the brake disc 2 and the winding bodies 3 with the winding grooves. Winding body 3 and brake disc 2 are connected to one another in such a way that they cannot twist against each other. The pull cables 4 are attached to the winding body 3 or the brake disc 2 and wound in opposite directions in the winding grooves.

Sie führen aus dem Gehäuse 5 hinaus; am freien Ende befinden sich Handgriffe 6. Der Ansatz dieser Handgriffe ist derart ausgebildet, daß die Zugseile 4 darauf aufgewickelt und in einer Klampe oder Klemme belegt werden. Dadurch läßt sich die Zugseillänge verstellen.They lead out of the housing 5 ; handles 6 are located at the free end. The approach of these handles is designed in such a way that the traction cables 4 are wound thereon and occupied in a cleat or clamp. This allows the cable length to be adjusted.

Auf die Bremsscheibe 2 wirken zwei Bremsklötze 8 ein, die an einer Bremszange 9 befestigt sind.Two brake pads 8 , which are fastened to a brake caliper 9 , act on the brake disc 2 .

Der aus Gurtband bestehende Haltegriff 7 ist gegenüber der Zugseildurchführung derart an der Bremszange befestigt, daß sie sich zusammenzieht und dabei die Bremsklötze 8 gegen die Bremsscheibe 2 drückt, sobald Zug auf den Haltegriff 7 kommt.The strap 7, which is made of a webbing, is fastened to the brake caliper in relation to the pulling cable feedthrough in such a way that it contracts and thereby presses the brake pads 8 against the brake disc 2 as soon as the handlebar 7 is pulled.
