Abstract

The apparatus which is the subject of the invention comprises an endless flexible rope 1 forming a ring which slides over a fixed drum 2 carried by a framework, and also over two drums 3 and 3' which are fixed in rotation and linked rigidly to a pivoting shaft 4 which is also fastened to the framework, around which they can pivot. This shaft is held immobilised in various positions which varies the angle of friction (angle of resistance) of the cable over the drums and the traction force on 1 at A. This apparatus may serve for sports training in climbing a smooth rope and other muscle-development exercises.

Description

La présente invention concerne un appareil de simulation de grimper à la corde lisse.The present invention relates to an apparatus for simulating climbing on a smooth rope.

Le grimper à la corde lisse,exercice utilitaire,présente les inconvénients suivants pour sa pratique:opposition de toute la masse du corps du pratiquant à soulever,donc aucune progressivité ,ce qui rebute le débutant - nécessité d'un local assez haut pour soutenir la corde,avec les difficultés que cela entraîne.Climbing the rope, a utility exercise, has the following drawbacks for its practice: opposition of the entire mass of the practitioner's body to lift, therefore no progressiveness, which puts off the beginner - need for a room high enough to support the rope, with the difficulties that this entails.

-impossibilité pour un éducateur de se tenir pres du pratiquant pour le conseiller- danger de chute d'autant plus grave que la fatigue croit rapidement avec la hauteur d'élévation du pratiquant,qui doit encore redescendre- limitation du temps travail par la longueur de la corde - limitation de l'effort a' celui du poids l'utilisateur.- inability of an educator to stand near the practitioner for the counselor - danger of falling all the more serious as fatigue quickly increases with the height of elevation of the practitioner, which must still descend - limitation of the working time by the length of the rope - limiting the effort to that of the user's weight.

L'apoareil objet de l'invention évite tous ces inconvénients:progressivité,local nécessaire très courant,travail au sol,durée de travail illimitée,effort possible développé netse;uènt supérieur au poids de l'utilisateur.The device object of the invention avoids all these drawbacks: progressiveness, very necessary local necessary, work on the ground, unlimited working time, possible effort developed netse; uènt greater than the weight of the user.

Il comporte essentiellement , une corde souple en sans fin ,qui glisse sur un tambour fixe sur une ossature qui le porte,et sur deux autres tambours fixes en rotation et liés riidement a un axe de pivotement blocable,également porte par deux coussinets par l'ossature.En fiziisant pivoter ces deux tambours autour de l'axe de pivotement ,on modifie la somme des arcs d'enroulement de la corde sur l'ensemble des tgnbours.De ce fait ,l'effort de traction sur l'un des brins de la corde (brin tendu ) varie dans des proportions très grandes,suivant les lois élémentaires de la mécanique,avec cet arc d'enroulement,avec comme seule tension d'ope position(brin mou)le seul poids d'une partie de la corde.Un léger eontreooids po- sé sur la boucle inférieure permet d'amplifier énormément cet effort.It essentially comprises, an endless flexible rope, which slides on a fixed drum on a frame which carries it, and on two other fixed rotating drums linked rigidly to a lockable pivot axis, also carried by two bearings by the By rotating these two drums around the pivot axis, we modify the sum of the winding arcs of the rope on all the towers. As a result, the tensile force on one of the strands of the rope (stretched strand) varies in very large proportions, according to the elementary laws of mechanics, with this winding arc, with the only tension of ope position (soft strand) the only weight of part of the A slight eontreooids placed on the lower loop makes it possible to amplify this effort enormously.

Les croquis annexés précisent ces différents points
La figure I renrésente un tambour fixe sur lequel glisse un lien souple dans le sens de la flAche.Si T et t sont les efforts qui agissent sur les extrémités de ce lien,f étant le coefficient de frottement lien/ tambour et e la base des logarithnes népériens, on a la relation classique:T = t esB
La figure 2 schématise une solution proposée pour l'appareil : la corde en sans fin I qui passe sur un tambour fixe 2 ainsi que sur deux autres tambours 3 et 3' fixes en rotation et liés rigidement lun à l'autre ainsi qu'à un axe de pivotement 4;L'angle d'enroulement global de la corde qur ces tambours est #=#2+#3+#3'
Un poids additionnel 5 glissant peut eAtre posé sur la boucle inférieure de la corde.The attached sketches specify these different points
Figure I shows a fixed drum on which a flexible link slides in the direction of the arrow. If T and t are the forces which act on the ends of this link, f being the coefficient of friction link / drum and e the base of natural logarithnes, we have the classical relation: T = t esB
Figure 2 shows schematically a solution proposed for the device: the endless rope I which passes over a fixed drum 2 as well as over two other drums 3 and 3 'fixed in rotation and rigidly linked to each other and to a pivot axis 4; The overall winding angle of the rope that these drums is # = # 2 + # 3 + # 3 '
An additional sliding weight 5 can be placed on the lower loop of the rope.

La figure 3 schématise une variante à la solution précédente:la tension du cable en amont du tambour fixe 2 est donnée par le pincement variable de la corde entre deux mâchoires 7 .Le tambour 2 peut également 8tre libre en rotation. Figure 3 shows schematically a variant of the previous solution: the cable tension upstream of the fixed drum 2 is given by the variable clamping of the rope between two jaws 7. The drum 2 can also be free to rotate.

La figure 4 présente une autre variante èux solutions présentées par les précédentes:le tambour 2 est mobile en rotation ;la corde I est solidarisée au tambour 2 par une enroulement de plusieurs tours sur celui-ci; le tambour 2 est pincéentre deux mâchoires 6 qui opposent uncouple de freinage à la rotation du tambour par é l'intermédiaire d'un ressort à tension variable qui apnlique une force F sur les surfaces frottantes de ces mâchoires. FIG. 4 shows another variant of the solutions presented by the previous ones: the drum 2 is movable in rotation; the rope I is secured to the drum 2 by a winding of several turns on it; the drum 2 is pinched between two jaws 6 which oppose a braking torque to the rotation of the drum by means of a spring with variable tension which applies a force F to the friction surfaces of these jaws.

La figure 5 représente un ensemble suivant schéma de la figure 2 avec son ossature support 8 et plancher autonome,conportant des sangles 9 fixés rigidement au planche à oroiirnité de la oartie vivant de la corde où se tient l'utilisateur.FIG. 5 represents an assembly according to the diagram of FIG. 2 with its support frame 8 and autonomous floor, comprising straps 9 rigidly fixed to the board with the orientation of the living part of the rope where the user stands.

L'appareil objet de l'invention est constitué de façon préférentielle,sans que cela soit une condition limitative, par une corde en sans fin ,corde souple, opposant un effort de glissement à l'effort manuel de traction T sur l'un de ses brins(fig 2)Cette corde Dasse sur un tambour 2 fixe en rotation,porté nar une ossature 8 - fig 5 , et sur deux autres tambours 3 et 3',liés rigidement l'un à l'autre ainsi qu'à un axe de pivotement 4 qui les norte par l'intermédiaire d'une pièce de liaison,Cet axe porté nar deux paliers fixés è 11 ossature support 8,fait prendre diverses positions dans l'espace aux tambours 3 et 3'.Un système de bl.o- cage approprié immobilise les tambours 3 et 3" dans la. position choisie nar l'utilisateur. Ce système a pour but de faire varier l'angle total d'enroulement de la corde sur les tambours :( e = + e+ e3) De cette façon les force de trac-.  The device which is the subject of the invention preferably consists, without this being a limiting condition, of an endless rope, flexible rope, opposing a sliding force to the manual traction force T on one of its strands (fig 2) This rope Dasse on a drum 2 fixed in rotation, carried nar a frame 8 - fig 5, and on two other drums 3 and 3 ', rigidly connected to each other and to a pivot axis 4 which norte them via a connecting piece, This axis carried nar two bearings fixed to 11 support frame 8, makes take various positions in space to the drums 3 and 3 '. A system of bl .o- suitable cage immobilizes the drums 3 and 3 "in the position chosen by the user. This system aims to vary the total angle of winding of the rope on the drums :( e = + e + e3 ) In this way the force of trac-.

tion T sur un brin de la. corde varie avec # ,la force d'opposition t à laquelle
T est lié par la relation T = t e ,étant sensiblement constante et égale au poids propre de l'autre brin de la cordcUn poids glissant 5 permet d'anplifier
T par augmentation de t.tion T on a strand of the. string varies with #, the opposing force t at which
T is linked by the relation T = te, being substantially constant and equal to the self-weight of the other strand of the cord. A sliding weight 5 makes it possible to amplify
T by increasing t.

Dans cette réalisation l'angle d'enroulement #2 peut prendre les valeurs: # I,5#,2,5#;(# étant égale à 3,I4I6 radians ). In this embodiment the winding angle # 2 can take the values: # I, 5 #, 2.5 #; (# being equal to 3, I4I6 radians).

La lasse glissante additive posée sur le brin inférieur de la coide,nermet d'augmenter.notablement la force T et de couvrip une gamme étendue d'efforts ,permettant de dépasser le poids de l'utilisateur.Dens ce cas ,afin de maintenir celui-ci au sol et de compenser la différencie entre l'effort T et le poidsP de cet utilisateur,une paire de sangles situées à proiimité de la verticale à l'ef- fort T est fixée fermement au plancher pour permettre à cet utilisateur d'y glisser les pieds qui s'y trouvent calés par le dessusen le maintenant au niveau du sol.The additive sliding lass posed on the lower strand of the coide, allows to increase notably the force T and to cover a wide range of efforts, allowing to exceed the weight of the user. In this case, in order to maintain that -this on the ground and to compensate for the difference between the force T and the weightP of this user, a pair of straps located near the vertical to the force T is fixed firmly to the floor to allow this user to slide the feet in there wedged from above, keeping it at ground level.

Une variante à la solution précédente,consiste à remplacer l'ensemble des poulies 3 et 3' par deux mâchoires 7-fig3, pincement réglable ,qui pincent le câ- ble en créant un effort t.De cette variante dérive une autre solution ,dans laquez le tambour 2 tourne librement autour d'un axe ,l'effort t étant alors égal à l'effort de pincement t.A variant of the previous solution consists in replacing all the pulleys 3 and 3 'with two jaws 7-fig3, adjustable toe-in, which pinch the cable creating a force t. From this variant comes another solution, in lacquer the drum 2 rotates freely around an axis, the force t then being equal to the pinch force t.

Une autre solution ,fig 4 ,consiste à creer un couple de frottement réglable C qui s'oppose à la rotation dutambour 2 qui peut tourner autour de son axe.La corde s'enroule dans ce cas de plusieurs tours sur le tambour pour créer l'adhé- rence nécessaire à son entrainement et sur lequel le cable ne doit pas glisser.Another solution, fig 4, consists in creating an adjustable friction torque C which opposes the rotation of the drum 2 which can turn around its axis. The rope is wound in this case by several turns on the drum to create the adhesion necessary for its training and on which the cable must not slip.

La force de traction est alors T - ci r. Le couple de frottement est obtenu par une ou deux mâchoires sur lequel agit une force F qui orée le frottement nécessaire par un système de vis et ressort de compression classique.The tensile force is then T - ci r. The friction torque is obtained by one or two jaws on which a force F acts which provides the friction required by a conventional screw and compression spring system.
