Definitions
- the present invention relates to a gymnastics apparatus with rocker beams according to the preamble of patent claim 1.
- the major part of these proposals relates to a beam (which is already to be distinguished here from the wooden swinging beam of the playgrounds), which is pivotable about a pivot and is provided with a single, sliding along the beam seat.
- the user who holds himself by a handle and holds his feet against the other end of the bar, shifts his weight along the bar, causing him to rock.
- the beam may be provided with a device which dampens the rocking.
- a device similar to this construction is disclosed in US Pat. US 2,190,795 showing a beam that swings about a central axis and is provided at each end with a seat mounted on the beam.
- Each of these seats is equipped with a handle bar with pedal, the lever that connects the handle with its pedal, is pivotable about an axis fixedly mounted on the beam.
- a push rod mechanism with tie rods between the pedals of the handles longitudinally move the bar forward and backward, causing the bar to rock about the central axis.
- the main drawback here is that the two users are almost unable to interact with each other because the two seats are coupled in their movements and therefore can not develop the playful aspect that one might expect from such a device ,
- German utility model no. DE-202005019263U1 shows a beam with two fixed seats and associated handles that do not pivot about a swing axis, but are supported at two points on a semi-circular guide. In this way, the bar performs not only the rocking motion but also a translational movement.
- the device is intended as a swinging rocker on playgrounds for children, and there is no indication to find utility as a muscle strengthening device.
- the article is of interest only because of the use of a hemispherical guide.
- the purpose of the present invention is to improve the usefulness of the known swinging beams, on the one hand by enhancing the gymnastics aspect and on the other by introducing a strong playful aspect in the application, which makes the use of the apparatus entertaining and thus more satisfactory than in the previously known Devices.
- Another purpose, particularly important for certain sports, is then the possibility to use the apparatus according to the invention for improving the synchronous movement of the two users.
- One of the main things to remember is the training of a pair of oarsmen on a two-man without helmsman, where the synchronism between the two athletes plays an important role.
- the two seats in their movement along the corresponding guide are independent of each other, because thanks to this interpretation, the two users succeed in developing the playful aspect of the apparatus, for example, by trying to surprise each other in their movements, or the aspect of mutual synchronism, in that they seek to coordinate their movements in the best possible way, in which a more or less intensive gymnastic exercise is exercised - the intensity of which can be adjusted according to other characteristic features, with special arrangements able to influence the momentum of the swinging movement around the fulcrum.
- a beam 1 which swings about a rotation axis 2.
- the swing axis of rotation 2 is arranged substantially in the center of the length of the beam 1, at right angles to the longitudinal extent of the beam.
- substantially in the center is to be understood according to a preferred embodiment of the invention that the rocking axis 2 in the longitudinal direction of the beam 1 between two extreme positions can be displaced with respect to the axis of symmetry at right angles to the longitudinal expansion of the beam 1, wherein the axis of symmetry which has been referred to above for simplicity as "center of the beam 1".
- This displacement of the rocking axis 2 between two outermost points can be accomplished both in a continuous displacement (or at all points of the distance between the two outermost positions) or as a discontinuous displacement (or along a series of fixed points).
- This shift of the swing axis 2 relative to the bar 1 is mainly used to compensate for any weight differences between the two users, because it is clear that if a trainee is much heavier than the other, the beam 1, even with all mechanisms for swing damping of the Bar 1 itself, which may be provided as a further embodiment, tends to lower to the side of the heavier user, whereby the balancing effect of the swing of the beam 1 due to the actions of the two users on the seats almost or completely disappears, so the action, on which the playful aspect of the apparatus as well as the desired synchronization effect of the movements is strongly based.
- the basic feature of the present invention is that the gymnastics apparatus has at each end A and B of the beam 1 a seat 4 and a seat 5, both displaceable along suitable guides 6 and 7, respectively, substantially parallel to the longitudinal extent of the beam 1 are.
- the guides do not necessarily have to be straight (as in the US Pat Fig. 1 but also slightly deviated from the straightness, for example, may also be curved, as is the case in a preferred embodiment of the present invention, which will be explained in more detail below.
- each guide 6, 7 is then provided with a handle bar 8, 9 which is connected to the corresponding guide 6, 7 and to a foot support 10 fixed to the end of the guide 6, 7 and directed against the swing axis 2 of the beam 1 , 11 is connected (but not necessarily fixed, as set forth below in the description of another preferred embodiment).
- the handles 8, 9 and the foot supports 10, 11 are essential for the correct execution of the exercises, as described below with reference to the Figures 3 and 4 is explained.
- the guides 12, 13 are curved in a semicircular shape, wherein the central point of the guides 12 and 13 is that which is located closest to the surface of the beam 1. All the same elements shown in this figure and in the following figures are designated by the same reference numerals.
- FIGS. 1 to 4 In the representations of the FIGS. 1 to 4 is indicated at 14 a central support point at which the swing axis of rotation 2 of the beam 1 is fixed, or the support 3, on which the beam 1 is fixed,
- the present invention further provides in a preferred embodiment, that the rocking axis 2 of the beam 1 is provided with an elastic device 15 which holds the beam 1 in the rest position, ie without load by the user, substantially horizontally.
- the force (or the torque) exerted by the elastic device on the swing axis of rotation 2 is adjustable between a minimum and a maximum value, which can be achieved in different ways, depending on the type of elastic device 15 can.
- the selection is the responsibility of the person skilled in the art and requires no further particular description here.
- the purpose of this adjustment is to adapt the mobility of the beam 1 to the weight of the user and their muscular strength requirements: the larger the weight, the greater the physical effort to be applied, and the greater the force that the elastic device will provide as a “stabilizer "for the position of the beam 1 must be exercised on it.
- the elastic device 15 fulfills its elastic function, it can, for example, according to a first preferred embodiment, two biased or biased coil springs 16 and 17 ( FIGS. 1 and 2 ), whose one of the ends 18, 19 is each attached to an attachment point on the beam 1 or on its support 3, wherein these points are arranged symmetrically to the swing axis of rotation 2 of the beam 1.
- the elastic device 15 comprises two coil springs 20 and 21 (of which only the spring 20 is visible, because the other is on the concealed by the central support 14 side) on the swing axis of rotation. 2 acting on the beam 1 and with one spring a moment clockwise and with the other a moment in the counterclockwise direction exert on it, so that the beam 1 is held in its substantially horizontal rest position.
- a suitable provision ensures that the coil springs 20 and 21 are more or less tensioned according to the force to be exerted on the swing pivot axis 2.
- the elastic device 15 cooperates with a damping device 34 which damps the rocking movement of the beam 1.
- a damping device 34 which damps the rocking movement of the beam 1.
- a damping system 34 which consists of a pair of hydraulic cylinders with pistons 34 'and 34 "connected by a conduit in which a cock 35 is installed
- the side which descends, the liquid in the cylinder on the other side, which raises, the change of the damping parameter is accomplished by means of the cock 35, which adjusts the opening of the connection between the two cylinders, the position with largest opening at which the liquid flows through the most quickly and the position with the smallest opening at which the liquid flows through the slowest.
- the elasticity parameter is set by means of mechanical systems which are already known in the prior art, namely the pretensioning of the springs, if they are used as tension springs, or their preloading, if they are used as compression springs.
- the purpose of these settings is to adjust the mobility of the beam 1 the weight and the demands on the muscular strength of the user: the greater their weight and the greater their expended physical effort, the greater should be the opposite of the elastic device 15 resistance and damping 35th be against the rocking movement of the beam 1.
- the guides 6, 7 and 12, 13 via the small support 22 are rigidly connected to the beam 1.
- the guides can therefore perform no movement relative to the beam 1.
- the handle bar 24 of two horizontal handles 24 ', 24 "( Fig. 6 ) (which may also be joined together) and two lateral arms 25, 26 which are movable in the vertical direction is formed.
- Each of the two lateral arms 25, 26 is connected to the corresponding guide 23 by means of a displaceable pivot axis 27 and 28 (see Fig. 6 ), and is in turn connected by means of a pivot axis 29, 30 with the corresponding side of the beam 1.
- the guide 23 is pivotally mounted on the beam 1 by means of a further pivot axis 31.
- the two pivot axes 27, 29 and 28, 30 of each of the lateral arms 25 and 26 of the handle bar 24 are arranged in such a manner (as in the FIGS. 4 and 5 shown) that the approach of the handle bar 24 to the body of the user causes the raising of the end of the guide 23, opposite to where the handle bar 24 is located.

Abstract
Description
Die vorliegende Erfindung betrifft einen Gymnastik-Apparat mit Wippbalken gemäss dem Oberbegriff des Patentanspruchs 1.The present invention relates to a gymnastics apparatus with rocker beams according to the preamble of patent claim 1.
Ähnliche Apparate sind sowohl aus der Praxis als auch aus der Patentliteratur bekannt. In ihrer einfachsten Form finden sich solche auf Kinderspielplätzen; sie bestehen aus einem einfachen Balken der um einen horizontalen Stift schaukeln kann und zwei je an einem Ende des Balkens angebrachten Sesselchen. Die Kinder steigen auf je einer Seite auf und lassen die Schaukel wippen, indem sie abwechslungsweise mit den Füssen am Boden abstossen. Zwei Schraubenfedern, je an einem Ende des Balkens angebracht, begrenzen den Ausschlagwinkel der Schaukelbewegung wodurch auch die starken Schläge vermieden werden, die ein harter Anschlag hervorrufen würde. Hierbei handelt es sich um einen rein unterhaltsamen Apparat für Kinder, ohne jeden Anspruch auf Gymnastik-Anwendungen.Similar apparatus are known both from practice and from the patent literature. In their simplest form, such are found on children's playgrounds; They consist of a simple beam that can swing around a horizontal pin and two armchairs each attached to one end of the beam. The children climb up on each side and let the swing teeter by alternately pushing their feet off the ground. Two coil springs, each attached to one end of the beam, limit the swing angle of the rocking motion, thereby avoiding the heavy blows that a hard impact would cause. This is a purely entertaining device for children, without any claim to gymnastics applications.
Ausgehend von diesem einfachen Prinzip sind verschiedene Varianten des Schaukelbalkens vorgeschlagen worden, welche die Schaukel zunehmend zu einem mehr oder weniger komplexen Gymnastik-Gerät gewandelt haben, das sich hauptsächlich auf die Muskulatur des Benutzers ausrichtet, wobei der dem Prinzip zweifelsohne innewohnende spielerische Aspekt verloren gegangen ist.Based on this simple principle, various variants of the rocking bar have been proposed, which have increasingly transformed the swing to a more or less complex gymnastics device, which focuses mainly on the user's musculature, wherein the principle of the inherent playful aspect is undoubtedly lost ,
Der Grossteil dieser Vorschläge betrifft einen Balken (der bereits hier vom hölzernen Schaukelbalken der Spielplätze zu unterscheiden ist), der um einen Drehpunk schwenkbar ist und mit einem einzigen, längs des Balkens verschiebbaren Sitz versehen ist. Der Benutzer selbst, der sich an einem Griff hält und seine Füsse gegen das andere Ende des Balkens gerichtet hält, verschiebt sein Gewicht längs des Balkens und bringt diesen so ins Schaukeln. Der Balken kann mit einer Vorrichtung versehen sein, die das Wippen dämpft.The major part of these proposals relates to a beam (which is already to be distinguished here from the wooden swinging beam of the playgrounds), which is pivotable about a pivot and is provided with a single, sliding along the beam seat. The user, who holds himself by a handle and holds his feet against the other end of the bar, shifts his weight along the bar, causing him to rock. The beam may be provided with a device which dampens the rocking.
Andere klassische Beispiele solcher Apparate sind die Rudergeräte, wie sie in Fitness-Studios oder als Heimtrainer gebräuchlich sind. Zweifellos können solche Geräte zur Stärkung der Muskulatur der Arme, Beine und des Rückens dienen; sie sind jedoch nur für eine Person ausgelegt und bieten daher keinerlei spielerischen Aspekt, so dass deren Anwendung langweilig und endlos wiederholt erscheint.Other classic examples of such devices are the rowing machines, such as are common in gyms or as exercise bikes. Undoubtedly, such Devices to strengthen the muscles of the arms, legs and back serve; however, they are designed for one person only and thus do not provide any playful aspect, making their application boring and endlessly repetitive.
In Bezug auf die Patentliteratur ist auch aus dem Deutschen Gebrauchsmuster Nr.
Ein dieser Konstruktion ähnliches Gerät ist in der Amerikanischen Patentschrift Nr.
Nebst der mechanischen Kompliziertheit des Apparates besteht auch hier der Hauptnachteil darin, dass die beiden Benutzer fast nicht miteinander interagieren können, da die beiden Sitze in ihren Bewegungen gekoppelt sind und daher den spielerischen Aspekt, den man von einem solchen Gerät erwarten könnte, nicht entwickeln können.In addition to the mechanical complexity of the apparatus, the main drawback here is that the two users are almost unable to interact with each other because the two seats are coupled in their movements and therefore can not develop the playful aspect that one might expect from such a device ,
Ein weiteres interessantes Dokument, nämlich das Deutsche Gebrauchsmuster Nr.
Der Zweck der vorliegenden Erfindung ist, die Verwendbarkeit der bekannten Schaukelbalken zu verbessern, einerseits durch Verstärken des Gymnastik-Aspektes und anderseits durch Einbringen eines starken spielerischen Aspektes in der Anwendung, wodurch die der Gebrauch des Apparates unterhaltsam und damit befriedigender wird als bei den bisher bekannten Geräten.The purpose of the present invention is to improve the usefulness of the known swinging beams, on the one hand by enhancing the gymnastics aspect and on the other by introducing a strong playful aspect in the application, which makes the use of the apparatus entertaining and thus more satisfactory than in the previously known Devices.
Ein weiterer Zweck, besonders wichtig für bestimmte Sportarten, ist sodann die Möglichkeit, den erfindungsgemässen Apparat zum Verbessern der synchronen Bewegung der beiden Benutzer zu verwenden. Dabei ist vor allem zu denken an das Training eines Paars Ruderer auf einem Zweier ohne Steuermann, wo der Synchronismus zwischen den beiden Athleten eine wichtige Rolle spielt.Another purpose, particularly important for certain sports, is then the possibility to use the apparatus according to the invention for improving the synchronous movement of the two users. One of the main things to remember is the training of a pair of oarsmen on a two-man without helmsman, where the synchronism between the two athletes plays an important role.
Diese Ziele werden erreicht mittels eines Apparates gemäss dem Oberbegriff des Anspruchs 1, dessen Eigenschaften dem kennzeichnenden Teil des Anspruchs 1 entsprechen, was im wesentlichen darin besteht, dass an jedem der Enden des Balkens ein Sitz vorhanden ist, der längs geeigneten Führungen verschiebbar ist, wobei jeder der Führungen eine Griffstange und eine Fuss-Stütze zugeordnet ist. Grundlegend ist sodann, dass die beiden Sitze in ihrer Bewegung längs der entsprechenden Führung voneinander unabhängig sind, denn dank dieser Auslegung gelingt es den beiden Benutzern, den spielerischen Aspekt des Apparates zu entwickeln, indem sie sich beispielsweise gegenseitig in ihren Bewegungen zu überraschen suchen, oder den Aspekt des gegenseitigen Synchronismus, indem sie ihre Bewegungen bestmöglich zu koordinieren suchen, wobei insgesamt eine mehr oder weniger intensive gymnastische Übung ausgeübt wird - deren Intensität gemäss andern kennzeichnenden Eigenschaften einstellbar ist, wobei besondere Vorkehrungen das Moment der Schaukelbewegung um den Drehpunkt beeinflussen können.These objects are achieved by means of an apparatus according to the preamble of claim 1, the characteristics of which correspond to the characterizing part of claim 1, which essentially consists in that at each of the ends of the beam a seat is provided along suitable guides is displaceable, wherein each of the guides is associated with a handle bar and a foot support. Basically, then, is that the two seats in their movement along the corresponding guide are independent of each other, because thanks to this interpretation, the two users succeed in developing the playful aspect of the apparatus, for example, by trying to surprise each other in their movements, or the aspect of mutual synchronism, in that they seek to coordinate their movements in the best possible way, in which a more or less intensive gymnastic exercise is exercised - the intensity of which can be adjusted according to other characteristic features, with special arrangements able to influence the momentum of the swinging movement around the fulcrum.

Diese Verschiebung der Schaukel-Achse 2 gegenüber dem Balken 1 dient hauptsächlich dazu, allfällige Gewichtsunterschiede zwischen den beiden Benutzern auszugleichen, denn es leuchtet ein, dass wenn ein Trainingsteilnehmer viel schwerer ist als der andere, der Balken 1, auch mit allen Mechanismen zur Schaukeldämpfung des Balkens 1 selbst, die als weitere Ausführungsvariante vorgesehen sein können, dazu neigt, sich auf die Seite des schwereren Benutzers abzusenken, wodurch der Ausgleichseffekt der Schaukelung des Balkens 1 infolge der Aktionen der beiden Benutzer auf den Sitzen fast oder ganz verschwindet, die Aktion also, auf welcher der spielerische Aspekt des Apparates sowie der erwünschte Synchronisationseffekt der Bewegungen stark beruht.This shift of the
Aus den beigefügten Abbildungen ist ersichtlich, dass die Vorkehrungen, die getroffen werden müssen, damit die Schaukel-Drehachse 2 des Balkens 1 verschiebbar gemacht werden können, weggelassen sind, weil es sich um Lösungen handelt, die jedem Fachmann auf dem Gebiet geläufig sind. Hier sei lediglich im Sinne eines Beispiels gezeigt, dass der Balken 1 in seiner Mitte auf einem separaten Abstützpunkt 3 aufliegen kann, und dass die Verschiebung der Schaukel-Drehachse 2 gegenüber dem Balken 1 dadurch bewerkstelligt werden kann, dass der Balken 1 einfach auf die eine oder die andere Seite gegenüber dem Auflagepunkt 3 verschoben wird, was beispielsweise für den Fall einer "kontinuierlichen" Verschiebung mittels einer Zahnschiene zwischen den beiden äussersten Punkten realisiert werden kann, oder im Fall der "diskontinuierlichen" Verschiebung mittels einer Reihe von Bohrungen und in bestimmte Bohrungen einzuschiebenden Stiften. Alles, was in den Abbildungen hier nicht dargestellt ist, entspricht dem bekannten Stand der Technik.From the attached figures it can be seen that the precautions that must be taken so that the swing axis of
Die grundlegende Eigenschaft der vorliegenden Erfindung ist, dass der Gymnastik-Apparat an jedem Ende A und B des Balkens 1 einen Sitz 4 bzw. einen Sitz 5 aufweist, die beide längs geeigneter Führungen 6 bzw. 7 im wesentlichen parallel zur Längsausdehnung des Balkens 1 verschiebbar sind. Hier ist auch zu unterstreichen, dass unter der Definition "im wesentlichen parallel zur Längsaudehnung des Balkens 1" (welcher Balken normalerweise gradlinig ausgebildet ist) zu verstehen ist, dass die Führungen nicht notwendigerweise gradlinig ausgebildet sein müssen (wie in der in der
Erfindungsgemäss ist sodann jede Führung 6, 7 mit einer Griffstange 8, 9 versehen, die mit der entsprechenden Führung 6, 7 sowie mit einer am Ende der Führung 6, 7 befestigten und gegen die Schaukel-Drehachse 2 des Balkens 1 gerichtete Fuss-Stütze 10, 11 verbunden ist (aber nicht notwendigerweise festgemacht ist, wie im folgenden in der Beschreibung einer anderen bevorzugten Ausführungsform dargelegt).According to the invention, each

Die vorliegende Erfindung sieht ferner in einer bevorzugten Ausführungsform vor, dass die Schaukeldrehachse 2 des Balkens 1 mit einer elastischen Vorrichtung 15 versehen ist, die den Balken 1 in der Ruhelage, also ohne Belastung durch Benutzer, im Wesentlichen horizontal hält.The present invention further provides in a preferred embodiment, that the rocking
Weiter ist vorgesehen, dass die von der elastischen Vorrichtung auf die Schaukel-Drehachse 2 ausgeübte Kraft (bzw. das Drehmoment) zwischen einem minimalen und einem maximalen Wert einstellbar ist, was je nach der Art der elastischen Vorrichtung 15 auf verschiedene Art und Weise bewerkstelligt werden kann. Die Auswahl obliegt dem Fachmann auf dem Gebiet und bedarf hier keiner weiteren besonderen Beschreibung. Diese Reguliermöglichkeit bezweckt, die Beweglichkeit des Balkens 1 dem Gewicht der Benutzer und deren Muskelkraft-Anforderungen anzupassen: Je grösser das Geicht, umso grösser sind die physischen Anstrengungen, die aufzubringen sind, und umso grösser ist die Kraft, die die elastische Vorrichtung als "Stabilisator" für die Lage des Balkens 1 darauf ausgeübt werden muss.It is further provided that the force (or the torque) exerted by the elastic device on the swing axis of
