Abstract

The gymnastic appts. has a seat (2) fixed by cables (4) that pass over pulleys (7) and are joined to a transverse handle (1). The double handle is a bar that is suspended by its centre so that whatever its inclination the seat will remain horizontal. The pulleys can pivot on the cable (3), with low torsional resistance, that suspend them from rings (8). The appts. can have four suspension cables so that the handle is attached to the cables at each end as well as in the centre.

Description

La présente invention a pour but de perfectionner l'appareil de suspension par les bras à traction réduite dont l'invention a fait l'objet du brevet 1490818 délivré à Madame BERARD le 26 juin 1967. The object of the present invention is to improve the suspension device by the arms with reduced traction, the invention of which was the subject of patent 1490818 issued to Madame BERARD on June 26, 1967.

Les moyens utilisées visent à ce que l'horizontalité du siège ne soit pas perturbée par les mouvements des bras de l'utilisateur. The means used aim to ensure that the horizontality of the seat is not disturbed by the movements of the user's arms.

Ces mouvements étant parfois non contrôlés,cette invention accroît donc la sécurité liée au fonctionnement de l'appareil.These movements being sometimes uncontrolled, this invention therefore increases the safety linked to the operation of the device.

L'appareil,tel qu'il est défini dans le brevet initial et ses certificats d'addition, comporte ee peignés indépendantes.Celà peut être un inconvenient quand l'utilisateur est un débutant.Par exemple en voulant faire une traotion,s'il fléchit inégalement les bras,il provoque l'inclinaison latérale du siège.Or le réflexe au débutant est tel que c'est sur la poignée la plus basse qu'il va tirer le plu pour reprendre son équilibrejce quisen augmentant l'inclinaison du siège,peut l'éjecter de celui-ci. The device, as defined in the initial patent and its certificates of addition, has independent combs. This can be a disadvantage when the user is a beginner. For example when trying to do a trauma, if unevenly flexes the arms, it causes the seat to tilt sideways. But the reflex at the beginner is such that it is on the lowest handle that it will pull the greatest amount to regain its equilibrium when increasing the seat tilt, can eject it from it.

Pour remédier à oet inconvénient le moyen utiliser consiste non seulement à supprimer l'indépendance des poignées,mais aussi à joint les extrémités des câbles de traction. To remedy this disadvantage, the means used consists not only in eliminating the independence of the handles, but also in joining the ends of the traction cables.

Les dessins annexes représentent un appareil du type balançoire à deux cibles (Fig.l) et un appareil du type balançoire à quatre câbles (Fig.2). Les cibles réfléchis sur poulies peuvent Otre,pour la clarté de la description,artificiellement divisés en deux parties une partie "suspentes" 4 qui s'attache au siège 2,une partie"traetior qui aboutit aux poignées. The accompanying drawings show a device of the swing type with two targets (Fig.l) and a device of the swing type with four cables (Fig.2). For the clarity of the description, the targets reflected on pulleys can be artificially divided into two parts, a "hanging" part 4 which attaches to the seat 2, a "traetior part which leads to the handles.

Les poignées indépendantes seront supprimées et remplacées par une double poignée qui pourra être une barre 1 assez longue (au moine 30cm) pour offrir une prise commode à l'utilisateur.Mais il ne faut pas attacher les câbles de traction aux extrémités de la barre,car un mouvement d'inclinaison de celle-ci entrainerait une inclinaison du siège en sens inverse.Les câbles de traction 5 doivent être réunis en aboutissant au milieu de la barre 1 de façon que celle-ci puisse être manoeuvrée dans tous les sens et prendre ainsi toutes les inclinaisons sans que le siège cesse d'être horizontal. The independent handles will be removed and replaced by a double handle which can be a bar 1 long enough (at least 30cm) to offer a comfortable grip for the user. But do not attach the traction cables to the ends of the bar, because a tilting movement of the latter would cause the seat to tilt in the opposite direction. The traction cables 5 must be joined by ending in the middle of the bar 1 so that it can be maneuvered in all directions and take thus all the inclinations without the seat ceasing to be horizontal.

Mais la stabilisation du siège ainsi obtenue,nécessitant la convergence des ombles vers le milieu de la poignée,requiert une modification importante au niveau du palan.On peut en effet constater dans le précédent brevet que les axes des poulies sont fixes par rapport à un référentiel lié à l'appareil.Par exemple la figure représentée sur la planche unique du dernier certificat d'addition montre des poulies dont les axes sont,deux à deux,parallèlement asservis dans un même bl
I1 faut donc rendre les poulies pivotantes,sinon les câbles de traction 5,désormais convergents et,par conséquent,sollicités dans des directions sortant du plan sagittal dn bloc de leurs poulies respectives,seraient le siège de frottements qui les useraient prématurément.Dans ce type d'appareils les poulies seront donc dégolidarisées pour que leur chape puisse tourner librement autour d'un axe confondu avec la direction des suspentes 4.
However, the stabilization of the seat thus obtained, requiring the convergence of char towards the middle of the handle, requires a significant modification at the level of the hoist. We can indeed note in the previous patent that the axes of the pulleys are fixed relative to a frame of reference linked to the device. For example the figure represented on the single plate of the last certificate of addition shows pulleys whose axes are, two by two, parallel controlled in the same bl
It is therefore necessary to make the pulleys pivoting, otherwise the traction cables 5, now convergent and, therefore, biased in directions leaving the sagittal plane in the block of their respective pulleys, would be the seat of friction which would wear them out prematurely. the pulleys will therefore be separated so that their yoke can rotate freely around an axis coincident with the direction of the lines 4.

L'articulation axiale utilisée pourra être mécanique.Pour l'appareil à quatre câbles,deux à deux convergeant vers l'anneau d'accrochage, il faut placer les poulies à un niveau tel qu'elles soient tout juste assez éloignées l'une de l'autre pour ne pas se heurter au cours du fonctionnement .Elles seront placées et articulées axialement au bout d'une tige rigide,d'une longueur répondant à cette conditicn,qui sera reliée par l'autre bout à l'anneau d'accrochage. The axial articulation used may be mechanical. For the device with four cables, two by two converging towards the hooking ring, the pulleys must be placed at a level such that they are just far enough apart from one the other so as not to collide during operation. They will be placed and articulated axially at the end of a rigid rod, of a length corresponding to this condition, which will be connected by the other end to the ring of hanging.

Ce problème de niveau ne se posant pas pour l'appareil à deux cables,les poulies pourront s'articuler,s'il le faut,directement avec leur anneau d'accrochage. This level problem does not arise for the device with two cables, the pulleys can be articulated, if necessary, directly with their hooking ring.

Plus simplement on peut utiliser pour les deux types d'appareils un cordage fait de la même matière que les suspentes (chanvre,nylon,etc.); car le cordage,en raison de sa faible constante de torsion, supprime tous les problèmes liés à l'articulation des poulies. Une poulie pivotant d'un demi-tour dans chaque sens ne provoque,de la part de la corde à laquelle elle est suspendue,qu'une résistance negligeable.Comme l'angle de torsion requis par le fonctionnement de l'appareil est inférieur à 180 degrés,une simple corde de suspension peut donner à la poulie la mobilité souhaitée.Dans les deux figures les poulies 7 sont suspendues à des cordages 3 se trouvant dans le prolongement des suspentes 4.Ces cordages sont suffisamment longs pour qu'ils puissent d'une part,dans les deux types d'appareils,subir des torsions en offrant un minimum de resistance,d'autre part,dans le type d'appareils à quatre poulies, répondre à la condition d'éloignement des poulies.Les poulies peuvent ainsi être entraînées dans la direction où s'sxerce la traction des câbles 5 guidés par l'utilisateur.Il s'ensuit une diminution notable des frottements et,par suite,de l'usure des cibles. More simply one can use for the two types of apparatuses a cord made of the same material as the lines (hemp, nylon, etc.); because the rope, due to its low torsional constant, eliminates all the problems related to the articulation of the pulleys. A pulley swiveling half a turn in each direction causes only negligible resistance on the part of the rope to which it is suspended. As the angle of twist required by the operation of the device is less than 180 degrees, a simple hanging rope can give the pulley the desired mobility. In the two figures the pulleys 7 are suspended from ropes 3 lying in line with the hangers 4.These ropes are long enough to allow them to on the one hand, in both types of apparatus, to undergo torsions while offering a minimum of resistance, on the other hand, in the type of apparatus with four pulleys, to meet the condition of distance from the pulleys. thus be driven in the direction in which the traction of the cables 5 guided by the user is exerted. This results in a significant reduction in friction and, consequently, in the wear of the targets.

Ce moyen de stabilisation du siège,ainsi défini,c'est-à-dire par l'emploi d'une double poignée et de poulies pivotantes,trouvera une application notamment dans les versions de l'appareil du type balan çoire où l'utilisateur,pour se balancer,pourra tirer sur la barre 1, un peu comme on tire sur un aviron.Ces versions étant conçues pour s'accrocher aux portiques de jardin.  This seat stabilization means, thus defined, that is to say by the use of a double handle and pivoting pulleys, will find an application in particular in versions of the device of the swing type where the user , to swing, can pull on bar 1, a bit like pulling on an oar. These versions are designed to hang on garden frames.
