Die Erfindung betrifft einen Mechanismus des Getriebes an der Maschine zu den Kraftübungen von den Bewegungsorganen, der die Änderung der Belastung des Übenden ermöglicht.The invention relates to a mechanism of Gearbox on the machine to the strength exercises of the Organs of movement that change the load of the Enables practitioners.

Es sind verschiedenartige Mechanismen mit Getrieben an Maschinen zu den Kraftübungen von den Bewegungsorganen bekannt. Erwähnte Mechanismen ermöglichen dem Übenden die Belastung der krafttrainierten Körperteilen zu steigern oder zu vermindern. Im allgemeinen wird an den Übungsmaschinen ein aus Plattengewichten zusammengesetzter Mechanismus angewandt, die auf einen mit dem Seil an der Oberteil verbundenen Schieber aufgesetzt sind, wobei dasjenige Seil über Rollen geführt wird und weiterhin mit dem schwenkbaren Hebel einstellbar verbunden ist, dessen freie Hebelende den Lastarm für den Übenden darstellt. Steigerung oder Verminderung der zum Neigen des Hebels erforderlichen Kraft erfolgt durch Hinzufügen oder Wegnehmen der Plattengewichten, was die Änderung der Zugkraft des Seiles bewirkt. So eine Bauweise des Mechanismus eines Getriebes ist beispielsweise in dem Patent DE Nr. 3332520 beschrieben. Eine andere in dem Patent DE Nr. 4137046 beschriebene Bauweise des Mechanismus eines Getriebes ist so ausgeführt, daß ein Schwenkarm des Hebels mit der Spannplatte, an der die Plattengewichte befestigt sind, drehbar verbunden ist, und dieselbe Spannplatte auf den senkrechten Schieber aufgesetzt ist. Obwohl solche Bauweisen in Konstruktion und Fertigung einfach sind, gewährleisten sie eine genaue Einstellung des Wertes der Belastung des Übenden nicht, was zum Beispiel bei den Geräten mit den hydraulischen, pneumatischen oder elektromagnetischen Systemen erreichbar ist. Außerdem ist Lärm schwerwiegend an obenerwähnten in den angeführten Patenten beschriebenen Bauweisen, der durch die schichtweise gestapelte Plattengewichte, die während der Übungen gegenseitig anstoßen, verursacht wird.There are different types of mechanisms with gears on machines for strength exercises from the organs of movement known. Mechanisms mentioned enable the practitioner To increase the load on the strength-trained body parts or decrease. Generally, on the exercise machines a composed of plate weights Mechanism applied to the one with the rope on the Upper part connected slider are placed, whereby that rope is guided over rollers and continues with the pivotable lever is adjustably connected, the free lever end represents the load arm for the practitioner. Increase or decrease the tilt of the lever required force is done by adding or Taking away the plate weights, which is changing the Tensile force of the rope causes. Such a construction of the Mechanism of a transmission is for example in the Patent DE No. 3332520. Another in that Patent DE No. 4137046 described construction of Mechanism of a transmission is designed so that a Swivel arm of the lever with the clamping plate on which the Plate weights are attached, rotatably connected, and placed the same clamping plate on the vertical slide is. Although such constructions in construction and Manufacturing are simple, they ensure accurate Not setting the value of the burden on the practitioner, which, for example, with the devices with the hydraulic, pneumatic or electromagnetic systems is. In addition, noise is severe at the above in the construction methods described, the due to the plate weights stacked in layers, the nudging each other during the exercises.

Es ist die Aufgabe der vorliegenden Erfindung diese Nachteile zu eliminieren, so daß erfindugsgemäß der neue Mechanismus eines Getriebes mit einem Gegengewicht, das nur einzelnes Plattengewicht beinhaltet, ausgestattet ist, dagegen das Seil von dem System der Seilrollen an einem Arm des Hebels in der Nähe dessen Drehachse befestigt ist, und auf demjenigen Arm ein Klemmschieber mit Rollen, zwischen welchen das Seil verläuft, verschiebbar befestigt ist, wobei in der Drehachse ein Regelsystem zum Einstellen des Winkels zwischen beiden Armen des Hebels eingebaut ist. Weiterhin ist die Bauweise dem Erfindung gemäß dadurch gekennzeichnet, daß der Klemmschieber verschiebbar an der gesamten Länge des Armes des Hebels befestigt ist.
Ein anderes wesentliches Merkmal der Erfindung ist, daß das Gegengewicht durch Aufhängen an einem System der Seilrollen bei der Verschiebung in die Tiefstellung das Untergestell der Maschine nicht berührt.
Ebenfalls charakterisiert sich die Erfindung dadurch, daß der Klemmschieber in jeder Lage auf dem Arm gleichzeitig einen Anschlag für das Seil darstellt, das vorteilhaft aus einem Paar der Seile besteht, wobei der Befestigungspunkt dieselben Seile auf dem Arm außerhalb der Drehachse des Armes des Hebels liegt.
Außerdem charakterisiert sich die Erfindung dadurch, daß das mit dem Arm verbundene Regelsystem des Hebels auf der Achse befestigt ist, die mit dem Endstück verbunden ist, das eine vorteilhaft bogenförmig gestaltete Verlängerung des Armes darstellt.It is the object of the present invention to eliminate these drawbacks, so that, according to the invention, the new mechanism of a transmission is equipped with a counterweight which contains only a single plate weight, whereas the rope from the system of pulleys on an arm of the lever in the vicinity thereof Axis of rotation is attached, and on that arm a clamping slide with rollers, between which the cable runs, is slidably attached, a control system for adjusting the angle between the two arms of the lever being installed in the axis of rotation. Furthermore, the construction according to the invention is characterized in that the clamping slide is slidably attached to the entire length of the arm of the lever.
Another essential feature of the invention is that the counterweight does not touch the underframe of the machine when it is suspended from a system of rope pulleys when it is moved to the lower position.
The invention is also characterized in that the clamping slide in each position on the arm simultaneously represents a stop for the rope, which advantageously consists of a pair of ropes, the attachment point of the same ropes on the arm being outside the axis of rotation of the arm of the lever.
In addition, the invention is characterized in that the control system of the lever connected to the arm is fastened to the axis which is connected to the end piece, which represents an advantageously curved extension of the arm.

Die neue Bauweise bringt bedeutende Vorteile sowohl für den Hersteller der Maschinen zu den Kraftübungen von den Bewegungsorganen, als auch für die Übenden. Der neue Mechanismus ist bedeutend einfacher in der Konstruktion, und folglich auch in dem Herstellungsverfahren. Der Übende kann ganz einfach die Belastung an dem Druckarm des Hebels, der den Druck auf den Übenden ausübt, ändern, indem er die Lage des verschiebbaren Klemmschiebers an dem anderen Arm des Hebels ändert. Es ist auch sehr wichtig, daß der Klemmschieber außer der Rolle der Regulierung der Belastung, auch als ein Anschlag funktioniert, so daß der vom Übenden betätigte Hebel immer in die Ausgangsstellung sowohl bei Rechts- wie auch Linksdrehen zurückkehrt. Diese Funktion erweitert bedeutend das Anwendugsgebiet der beschriebenen Bauweise. Die neue Bauweise des Mechanismus ermöglicht die Belastung je nach Möglichkeiten des Übenden stufenlos zu ändern. Außerdem eliminiert die frei schwebende Aufhängung des Gegengewichtes den durch die zahlreiche Plattengewichte verursachten Lärm, sowie ermöglicht als Werkstoff von dem Gegengewicht zum Beispiel Beton anzuwenden, der als Werkstoff viel billiger ist, als die in anderen Lösungen angewandte Plattengewichte aus Stahl oder Gußeisen, die sonst während des Betriebes gegenseitig aufschlugen und sehr oft zersprangen.The new design brings significant benefits for both the manufacturer of the machines for the strength exercises of the Organs of movement, as well as for the practitioners. The new Mechanism is significantly simpler in construction, and consequently also in the manufacturing process. The practitioner can quite simply the load on the pressure arm of the lever, the puts pressure on the practitioner by changing the situation of the sliding clamp slide on the other arm of the Lever changes. It is also very important that the clamp slide besides the role of regulating the burden, too works as a stop so that the one from the practitioner always use the lever in the starting position Turning to the right as well as to the left returns. this function significantly extends the field of application of the described Construction. The new construction of the mechanism enables the Depending on the possibilities of the practitioner, the load increases continuously to change. It also eliminates the free-floating suspension of the counterweight due to the numerous plate weights caused noise, and as a material of the Counterweight, for example, use concrete as a material is much cheaper than that used in other solutions Plate weights made of steel or cast iron, which otherwise hit each other during operation and very often shattered.

Auf demjenigen Arm ist auch der Klemmschieber 8 mit Rollen 9, zwischen welchen das Seil 3 verläuft, verschiebbar befestigt. In der Drehachse 5 ist Regelsystem 10 zum Einstellen des Winkels α zwischen beiden Armen 7 und 11 des Hebels 6 eingebaut. Klemmschieber 8 ist an gesamten Länge des Armes 7 des Hebels 6 verschiebbar aufgesetzt. Endrolle 4 ist an der Säule 13 drehbar um die Drehachse 12, und Regelsystem 10 ist an der Säule 14 befestigt. Die Säulen 13 und 14 sind mit dem Untergestell 15 der Maschine verbunden. Gegengewicht 1 ist so an dem System der Seilrollen 2 aufgehängt, daß es immer frei in der Luft hängt, und folglich bei der Verschiebung in die Tiefstellung das Untergestell 15 der Maschine nicht berührt.An embodiment of the invention is shown in the drawings, in which: Fig. 1 - the schematic representation of the construction of the mechanism on the machine for the strength exercises in the side view, Fig. 2 - the machine with built-in mechanism and illustration of the practitioner on the machine in standing position when practicing the arm muscles and Fig. 3 - the machine with built-in mechanism and image of the practitioner on the machine in sitting position when practicing the leg muscles, Fig. 4 - again the side view of the machine of Fig. 1 , in which a pair of ropes was used to connect with the clamping slide, and foaming a detail, namely the swinging out of the arm of the lever, Fig. 5 - top view of a fragment of the mechanism of the transmission with the clamping slide is attached in the left end position, Fig. 6 - the same top view as in Fig. 5 , wherein the clamping slide is fixed in the right end position, Fig. 7 - an example of the machine with built-in mechanism Figure 8 - an example of the machine with built-in mechanism and image of the practitioner on the machine in a sitting position while practicing the leg muscles, Fig. 9 - the schematic representation of the machine with the mechanism of the transmission under load when turning to the left, and Fig. 10 - the same machine with the mechanism of the transmission under load when turning to the right.
The mechanism shown in FIGS. 1 to 3 of a gearbox on a machine for the strength exercises of the movement organs has counterweight 1 , which is connected by a system of pulleys 2 to the rope 3, which is connected to the arm 7 of the arm 7 via the end roller 4 Lever 6 near its axis of rotation 5 is attached. On that arm, the clamping slide 8 with rollers 9 , between which the cable 3 runs, is slidably attached. In the axis of rotation 5 control system 10 is installed for adjusting the angle α between the two arms 7 and 11 of the lever 6 . Clamping slide 8 is slidably mounted on the entire length of the arm 7 of the lever 6 . End roller 4 is rotatable on column 13 about axis of rotation 12 , and control system 10 is attached to column 14 . The columns 13 and 14 are connected to the base frame 15 of the machine. Counterweight 1 is suspended from the system of pulleys 2 in such a way that it always hangs freely in the air, and consequently does not touch the base frame 15 of the machine when it is moved to the lower position.

Mechanismus eines Getriebes gemäß dem Wesen der Erfindung ermöglicht stufenlose Regulierung der Belastung des Übenden durch Ändern der Lage des Klemmschiebers 8 auf dem Arm 7 des Hebels 6. Bei Änderung der Lage des Klemmschiebers 8 ändert sich die Länge 1 des Armes 7, auf die die Kraft P, die das Äquivalent der Belastung von dem Plattengegengewicht 1 darstellt, wirkt. Weil die Länge des anderen Armes 11 des Hebels 6 konstant ist, durch Änderung der Länge 1 auf dem Arm 7 wird die Größe der Kraft, die zum Ausschwenken des Hebels 6 nötig ist, reguliert. Das Seil 3, an Rollen 9 des Klemmschiebers 8 verlaufend, fixiert die Ausgangslage des Armes 7 immer in der waagerechten Position. Durch Ändern des Winkels α der Position des Armes 11 wird der Mechanismus des Getriebes zu verschiedenartigen Übungen angepaßt, was an einem Ausführungsbeispiel in der Fig. 2 und Fig. 3 zu sehen ist.
Der in der Fig. 4 bis Fig. 6 dargestellte verbesserte Mechanismus des Getriebes im Vergleich zu der Ausführung nach Fig. 1 charakterisiert sich dadurch, daß das Seil 3 aus einem Paar der Seile 31 und 32 besteht, wobei der Befestigungspunkt b dieselben Seile 31 , 32 auf dem Arm 7 außerhalb der Drehachse 5 des Armes 11 des Hebels 6 liegt. Das Seilpaar sichert erhöhte Dauerhaftigkeit. In diesem verbesserten Mechanismus des Getriebes ist das mit dem Arm 11 verbundene Regelsystem 10 des Hebels 6 auf der Achse 51 befestigt, die mit dem Endstück 71 verbunden ist, das eine bogenförmig gestaltete Verlängerung des Armes 7 darstellt. In dieser Lösung der Maschine, die ähnlich wie vorher den Mechanismus des Getriebes benutzt, ist das Gegengewicht 1 auf den Seilen 33 aufgehängt, die durch das System der Seilrollen 2 und Seilrollenblock 21 durchlaufend im Punkt a am Ständer der Maschine befestigt sind. In dieser Lösung, die das Seilpaar 31 und 32 beinhaltet, sowie bei der vorherigen Lösung mit dem Einzelseil 3, ist der Klemmschieber 8 in jeder Lage auf dem Arm 7 gleichzeitig ein Anschlag für diese Seile, wobei die Ausgangslage des unbelasteten Armes 7 immer in der waagerechten Position fixiert wird. Dagegen ermöglicht die Befestigung der Seile 31 , 32 außerhalb der Drehachse 5, was durch entsprechende Gestaltung des Endstückes 71 möglich ist, eine Festlegung des Klemmschiebers 8 auf dem Arm 7 im Bereich von 1=0 bis 1=max, was in Fig. 5 und Fig. 6 zu sehen ist.
Der Mechanismus des Getriebes nach dem Wesen der Erfindung ermöglicht die stufenlose Regulierung der Belastung des Übenden durch Änderung der Lage des Klemm- schiebers 8 auf dem Arm 7 des Hebels 6. Bei Verschiebung des Klemmschiebers 8 auf dem Arm 7 wird die Länge 1 des Armes 7 geändert, mit dem der Übende gegen die Seile 31 und 32 mittels der Rollen 9 des Klemmschiebers 8 drückt. Da die Länge des Armes 11 des Hebels 6 bei gegebener Übung konstant bleibt, wird die Größe der zum Schwenken des Armes 11 erforderlichen Kraft durch das Ändern der Länge 1 auf dem Arm 7 im Bereich von 1=0 bis 1=max reguliert. Mit Hilfe des Regelsystems 10 des Hebels 6 wird die Lage des Armes 11 gegenüber dem unbelasteten Arm 7 im Bereich des Winkels α von 0 Grad bis 360 Grad festgelegt, und die Ausgangslage des Armes 11 wird gemäß dem Bedarf an verschiedenen Übungen, die beispielsweise in Fig. 7 und Fig. 8 zu sehen sind, fixiert. Der Mechanismus des Getriebes gemäß der Erfindung ermöglicht Übungsanordnungen mit der rechtsdrehenden Bewegung zu bilden, das heißt im Uhrzeigersinn, was in Fig. 9 zu sehen ist, und mit der linksdrehenden Bewegung, was in Fig. 10 zu sehen ist.Mechanism of a transmission according to the essence of the invention enables the load of the practitioner to be regulated continuously by changing the position of the clamping slide 8 on the arm 7 of the lever 6 . When the position of the clamping slide 8 changes, the length 1 of the arm 7 changes , on which the force P , which is the equivalent of the load on the plate counterweight 1 , acts. Because the length of the other arm 11 of the lever 6 is constant, by changing the length 1 on the arm 7 , the magnitude of the force required to swing the lever 6 out is regulated. The rope 3 , running on rollers 9 of the clamping slide 8 , always fixes the starting position of the arm 7 in the horizontal position. By changing the angle α of the position of the arm 11 , the mechanism of the transmission is adapted to various exercises, which can be seen in an embodiment in FIGS. 2 and 3 .
The improved mechanism of the transmission shown in FIGS. 4 to 6 compared to the embodiment according to FIG. 1 is characterized in that the rope 3 consists of a pair of ropes 3 1 and 3 2 , the fastening point b being the same ropes 3 1 , 3 2 on the arm 7 lies outside the axis of rotation 5 of the arm 11 of the lever 6 . The pair of cables ensures increased durability. In this improved mechanism of the transmission, the control system 10 of the lever 6 connected to the arm 11 is fixed on the axis 5 1 , which is connected to the end piece 7 1 , which represents an arcuate extension of the arm 7 . In this solution of the machine, which uses the mechanism of the transmission similarly as before, the counterweight 1 is suspended on the ropes 3 3 , which are fastened continuously at point a on the stand of the machine by the system of rope pulleys 2 and rope pulley block 2 1 . In this solution, which includes the rope pair 3 1 and 3 2 , as well as in the previous solution with the single rope 3 , the clamping slide 8 is simultaneously a stop for these ropes in every position on the arm 7 , the starting position of the unloaded arm 7 always is fixed in the horizontal position. In contrast, the attachment of the ropes 3 1 , 3 2 outside the axis of rotation 5 , which is possible by appropriate design of the end piece 7 1 , allows the clamping slide 8 to be fixed on the arm 7 in the range from 1 = 0 to 1 = max , which is shown in FIG 5 and 6 can be seen.
The mechanism of the transmission according to the essence of the invention enables the load of the practitioner to be regulated continuously by changing the position of the clamping slide 8 on the arm 7 of the lever 6 . When the clamp slide 8 is moved on the arm 7 , the length 1 of the arm 7 is changed, with which the practitioner presses against the ropes 3 1 and 3 2 by means of the rollers 9 of the clamp slide 8 . Since the length of the arm 11 of the lever 6 remains constant for a given exercise, the magnitude of the force required to pivot the arm 11 is regulated by changing the length 1 on the arm 7 in the range from 1 = 0 to 1 = max . With the help of the control system 10 of the lever 6 , the position of the arm 11 relative to the unloaded arm 7 is determined in the range of the angle α from 0 degrees to 360 degrees, and the starting position of the arm 11 is determined according to the need for various exercises, for example in FIG . 7 and 8 can be seen, fixed. The mechanism of the transmission according to the invention enables training arrangements to be made with the right-hand rotation, i.e. clockwise, which can be seen in FIG. 9 , and with the left-hand rotation, which can be seen in FIG. 10 .
