Abstract

The handle (20) has a rigid main body (21) to which a manual gripping unit is connected by an elastic return member i.e. helicoidal torsion spring (31). The return member opposes force induced by a user using the handle to operate a force resisting system (15) by displacing the gripping unit with respect to the main body. The gripping unit includes a movable grip bar (23) connected to a metal rim. A plastic ring is fixed to the main body.

Description

La présente invention concerne une poignée destinée à être reliée à un système de résistance à une force, notamment par l'intermédiaire d'un câble ou d'une barre mobile, d'une machine de musculation et/ou de rééducation.The present invention relates to a handle intended to be connected to a force resistance system, in particular by means of a cable or a moving bar, a weight training machine and / or a re-education machine.

Actuellement, les appareils de musculation et/ou de rééducation physique de la partie haute du corps humain, notamment le torse et les bras, présentent globalement une structure rigide, ou bâti, comportant par exemple un banc ou un siège, un ou plusieurs système de résistance à une force, fonctionnant notamment à l'aide de poids réels ou virtuels (frottement, piston, ressorts ou autres moyens), de câbles, de poulies, de barres/leviers mobiles ou articulées et de poignées manuelles.At present, the bodybuilding and / or physical rehabilitation apparatus of the upper part of the human body, in particular the torso and the arms, generally have a rigid structure, or structure, comprising for example a bench or a seat, one or more resistance to a force, operating in particular using real or virtual weights (friction, piston, springs or other means), cables, pulleys, bars / levers movable or articulated and hand grips.

Or, ces poignées sont basiques, dans le sens où elles n'apportent aucune autre fonction que celle de faire office de moyen de préhension pour l'utilisateur. En simplifiant, il s'agit simplement de faire interface entre le(s) muscles(s) à faire travailler, par exemple les pectoraux, dorsaux, biceps, triceps, deltoïdes, et un système de résistance de la machine muni par exemple de contrepoids à soulever/laisser reposer alternativement.However, these handles are basic, in the sense that they provide no other function than that of acting as a means of grip for the user. Simplifying, it is simply an interface between the (s) muscles (s) to work, for example the pectorals, back, biceps, triceps, deltoid, and a resistance system of the machine provided for example counterweight lift / let stand alternately.

Ce type de machine, et donc de poignée, décrit notamment dans FR-A-2 623 720 , est très répandu dans les salles de sport ou dans les unités médicales de rééducation des hôpitaux.This type of machine, and therefore of handle, described in particular in FR-A-2,623,720 , is widely used in sports halls or medical rehabilitation units in hospitals.

Cependant, d'un point de vue ergonomie et efficacité, ces poignées ne sont pas du tout optimisées. Au contraire, du fait de leur forme, de la liaison qu'elles assurent entre le muscle à travailler et le système de résistance de la machine, les gestes effectués par l'utilisateurs peuvent provoquer des contraintes néfastes à l'entraînement ou à la rééducation dudit muscle. Des micro traumatismes peuvent donc survenir non seulement aux muscles mais également aux tendons ou à d'autres organes. Or, l'utilisation de ces machines est souvent basée sur la répétition d'un mouvement effectué plusieurs dizaines à centaines de fois. On comprendra donc aisément qu'il est indispensable d'améliorer ces poignées pour un meilleur confort d'utilisation et une meilleure efficacité des machines sur lesquelles elles sont montées.However, from an ergonomic and efficient point of view, these handles are not optimized at all. On the contrary, because of their shape, the link they provide between the muscle to work and the resistance system of the machine, the actions performed by the user can cause adverse constraints to training or rehabilitation said muscle. Micro traumas can occur not only to the muscles but also to the tendons or other organs. However, the use of these machines is often based on the repetition of a movement made several tens to hundreds of times. It is therefore easy to understand that it is essential to improve these handles for a better comfort of use and a better efficiency of the machines on which they are mounted.

Un but de la présente invention est donc de résoudre les problèmes cités précédemment à l'aide d'une solution simple à mettre en oeuvre, fiable et particulièrement ergonomique pour l'utilisateur.An object of the present invention is therefore to solve the problems mentioned above with a solution that is simple to implement, reliable and particularly ergonomic for the user.

La poignée 20 est également représentée seule sur la figure 5, en position de repos, et sur la figure 6 en position d'utilisation.The handle 20 is also shown alone on the figure 5 , in the rest position, and on the figure 6 in position of use.

Cette poignée 20 comprend un corps principal rigide 21 formant une coquille réalisée par exemple en matière plastique et comportant une cavité sensiblement hémisphérique 22. La cavité 22 présente une ouverture 22a, une surface interne 22b et un axe principal de symétrie XX'.This handle 20 comprises a rigid main body 21 forming a shell made for example of plastic and having a substantially hemispherical cavity 22. The cavity 22 has an opening 22a, an inner surface 22b and a main axis of symmetry XX '.

Un moyen de préhension manuelle 23, tel qu'une barre de section ronde, s'étend de manière diamétrale en travers de l'ouverture 22a. Cette barre 23 est rendue solidaire d'une couronne interne métallique 24, par exemple par soudure, présentant surface périphérique externe 24a en forme de portion de sphère coopérant avec la surface interne 25a d'une anneau périphérique 25 réalisé en matière plastique et monté par exemple à force dans la cavité hémisphérique 22. La collaboration de la couronne interne 24 et de l'anneau périphérique 25 forme une liaison rotule sphérique permettant à la barre de préhension 23 de pivoter sur un angle α mesurant ±20°, par rapport à une position initiale de repos, au regard du corps principal 21, cette rotation se faisant selon tout axe ZZ' perpendiculaire à l'axe principal XX'.A manual gripping means 23, such as a round section bar, extends diametrically across the opening 22a. This bar 23 is made integral with a metal inner ring 24, for example by welding, having outer peripheral surface 24a shaped sphere portion cooperating with the inner surface 25a of a peripheral ring 25 made of plastic and mounted for example in force in the hemispherical cavity 22. The collaboration of the inner ring 24 and the peripheral ring 25 forms a spherical ball joint connection allowing the gripping bar 23 to pivot on an angle α measuring ± 20 °, with respect to a position initial rest, with respect to the main body 21, this rotation being along any axis ZZ 'perpendicular to the main axis XX'.

A cet effet, l'anneau périphérique 25 est de réalisé dans une matière plastique ayant qualité de dureté et de glissement permettant à la barre 23 de pivoter en toute liberté, avec des frottements limités.For this purpose, the peripheral ring 25 is made of a plastic material having a quality of hardness and sliding allowing the bar 23 to rotate freely, with limited friction.

Un organe de rappel élastique 30, tel qu'un ressort hélicoïdal de torsion 31, relie la barre de préhension 23 au corps principal 21. Plus précisément, un ressort hélicoïdal 31 à spires 32 de section rondes s'étend dans la cavité hémisphérique 22, entre une languette de fixation 33 solidaire de la barre de préhension 23 et une plaque de fond 34 à laquelle il est soudé. Le ressort 31 est fixé à la languette 33 par un rivet 35. Les spires 32 du ressort hélicoïdal 31 serpentent en spirale et épousent la surface interne 22b de la cavité hémisphérique 22. Le ressort hélicoïdal 31 présente un coefficient de raideur en torsion déterminé et identique dans ses deux sens de torsion possible.An elastic return member 30, such as a helical torsion spring 31, connects the gripping bar 23 to the main body 21. More precisely, a helical spring 31 with round section turns 32 extends into the hemispherical cavity 22, between a fastening tab 33 secured to the gripping bar 23 and a bottom plate 34 to which it is welded. The spring 31 is fixed to the tongue 33 by a rivet 35. The turns 32 of the coil spring 31 spirally wind and fit the inner surface 22b of the hemispherical cavity 22. The coil spring 31 has a determined and identical torsional stiffness coefficient in both directions of possible twist.

Un moyen de réglage 36 de la raideur du ressort hélicoïdal 31, accessible depuis l'extérieur de la poignée 20, est prévu au niveau du sommet 21b de la coquille 21. Ce moyen 36 se présente sous la forme d'un bouton 37 mobile en translation (flèche TR) et rotation (flèche R) lié à la plaque fond 34 à l'aide de vis 38 de manière à pouvoir agir sur la raideur du ressort hélicoïdal 31 en resserrant ou relâchant ses spires 32. Une fois la raideur déterminée, le bouton 37 est bloqué dans la position choisie par l'intermédiaire d'une goupille 39 pénétrant dans une cavité 40 du corps principal 21.An adjustment means 36 of the stiffness of the coil spring 31, accessible from outside the handle 20, is provided at the top 21b of the shell 21. This means 36 is in the form of a button 37 movable in translation (arrow TR) and rotation (arrow R) linked to the bottom plate 34 with screws 38 so as to act on the stiffness of the coil spring 31 by tightening or loosening its turns 32. Once the stiffness determined, the button 37 is locked in the selected position via a pin 39 penetrating into a cavity 40 of the main body 21.

Le corps principal 21 de la poignée 20 est rendu solidaire du levier 17 par l'intermédiaire d'un cerclage 42 présentant localement un logement 44 recevant l'extrémité dudit levier et appartenant à un fourreau 43. Une goupille 45 est également prévue pour relier transitoirement le ressort 31 à la coquille 21 par l'intermédiaire du cerclage 42 afin d'empêcher la rotation de la poignée 20 lors du réglage de la raideur du ressort.The main body 21 of the handle 20 is secured to the lever 17 by means of a strapping 42 having locally a housing 44 receiving the end of said lever and belonging to a sleeve 43. A pin 45 is also provided to temporarily connect the spring 31 to the shell 21 through the strapping 42 to prevent the rotation of the handle 20 when adjusting the stiffness of the spring.

Le fonctionnement de la poignée 20 est le suivant.The operation of the handle 20 is as follows.

Au repos, la poignée 20 est par exemple en position basse, comme cela est illustré sur la partie gauche de la figure 1. Aucune force n'est exercée sur les poids 14 qui restent empilés.At rest, the handle 20 is for example in the lower position, as illustrated on the left side of the figure 1 . No force is exerted on the weights 14 which remain stacked.

Lorsque l'utilisateur tire sur la poignée 20 de manière à faire pivoter la tige 17 sur son axe YY' vers le haut (Cf. partie droite de la figure 1, et figure 2), cela exerce une force de traction sur le câble 15 correspondant au bras utilisé. Ceci a alors pour effet de lever le poids 14 (partie droite de la figure 1) dont l'utilisateur aura sélectionné la masse qu'il souhaite soulever pour son entraînement musculaire.When the user pulls on the handle 20 so as to pivot the rod 17 on its axis YY 'upwards (see right part of the figure 1 , and figure 2 ), this exerts a pulling force on the cable 15 corresponding to the arm used. This then has the effect of lifting the weight 14 (right part of the figure 1 ) whose user has selected the mass he wishes to lift for his muscular training.

Dans ce cas, la main attrape la poignée en position neutre, pouce vers l'avant. Le mouvement consiste alors à faire une rotation de l'avant bras, simultanément à sa remontée, de manière à amener les mains en supination, c'est-à-dire pouces vers l'extérieur. C'est ce que m'on appelle le travail phasique. Cette rotation se fait contre la résistance du ressort 31 engagé dans le corps principal hémisphérique 21 et dont l'enroulement des spires 32 est forcément inverse au mouvement. Le retour à la position de départ (travail tonique), c'est-à-dire l'abaissement de l'avant bras, se fait aussi contre la résistance du ressort 31 qui tend à reprendre sa position initiale.In this case, the hand catches the handle in the neutral position, inch forward. The movement then consists in turning the forearm simultaneously with its ascent, so as to bring the hands supinated, that is to say, inches outwards. This is called phasic work. This rotation is against the resistance of the spring 31 engaged in the hemispherical main body 21 and the winding of the turns 32 is inevitably inverse movement. The return to the starting position (tonic work), that is to say the lowering of the forearm, is also against the resistance of the spring 31 which tends to resume its initial position.

Comme cela est schématisé sur la figure 2, en position de repos, la prise en main se fait en position neutre A, barre 23 horizontale. Le mouvement (flèche T) à l'intérieur de la poignée 20 décrit sensiblement un quart de tour (90°) pour arriver en supination C en passant par une prono-supination B progressive et ceci contre la résistance du ressort 31 dans le corps principal 21.As is schematized on the figure 2 in the rest position, the grip is in neutral position A, horizontal bar 23. The movement (arrow T) inside the handle 20 substantially describes a quarter turn (90 °) to arrive in supination C via a progressive prono-supination B and this against the resistance of the spring 31 in the main body 21.

Sur les figures 3 et 4, une seconde machine de musculation 100 est représentée. Cette machine 100 permet le travail localisé de l'avant- bras de l'utilisateur, par exemple le travail des muscles supinateurs. Dans ce cas, l'utilisateur saisit les poignées face à lui, les paumes des mains vers le bas, pouces vers l'intérieur. Le mouvement de musculation consiste simplement à effectuer une rotation d'environ 180°, contre la force préréglée du ressort bloqué dans la poignée, amenant ainsi les pouces vers l'extérieur (sens S - travail phasique). Le retour (travail tonique) se fait en résistant au relâchement des spires.On the figures 3 and 4 a second bodybuilding machine 100 is shown. This machine 100 allows the localized work of the forearm of the user, for example the work of the supinator muscles. In this case, the user grasps the handles facing him, the palms of the hands down, thumbs inwards. The bodybuilding movement is simply about rotating about 180 °, against the preset force of the spring locked in the handle, thus bringing the thumbs outward (S-direction - phasic work). The return (tonic work) is done by resisting loosening of the turns.

Une autre machine (même représentation) permet de travailler les muscles pronateurs. Dans ce cas, les poignées sont inversées. La prise en main se fait paumes vers le haut et pouces vers l'extérieur. Le mouvement consiste à effectuer une rotation d'environ 180° vers l'intérieur (sens P). Le retour se fait également en résistant au relâchement des spires.Another machine (same representation) allows to work the pronator muscles. In this case, the handles are reversed. The grip is palms up and thumbs out. The movement consists of rotating about 180 ° inwards (P direction). The return is also done by resisting loosening of the turns.

Dans ces deux cas, la poignée constitue intrinsèquement une machine contenant sa propre source de résistance à l'effort.In both cases, the handle is intrinsically a machine containing its own source of resistance to effort.

Dans tous les cas représentés, la rotule reliant la barre de préhension 23 au corps principal 21 permet une rotation sur ±20° de ladite barre sur tout axe ZZ' perpendiculaire à l'axe principal de rotation XX'.In all cases shown, the ball connecting the gripping bar 23 to the main body 21 allows ± 20 ° rotation of said bar on any axis ZZ 'perpendicular to the main axis of rotation XX'.

Ainsi, la combinaison de la rotation sur l'axe XX' et de la liaison rotule permet au poignet de décrire une trajectoire en double hélice/spirale ou en « 8 » (dans un sens puis dans l'autre) qui est un mouvement fluide et naturel respectant la physiologie humaine.Thus, the combination of the rotation on the axis XX 'and the ball joint allows the wrist to describe a trajectory in double helix / spiral or in "8" (in one direction then in the other) which is a fluid movement and natural respecting human physiology.

En conclusion, l'importance des avantages procurés par la présente invention doit s'étendre à l'ensemble des machines de musculation ou de rééducation pour le haut du corps et ne pas se limiter aux deux cas donnés à titre d'exemple.In conclusion, the importance of the benefits provided by the present invention should extend to all bodybuilding or rehabilitation equipment for the upper body and not be limited to the two cases given by way of example.

Le risque de microtraumatismes lors de l'utilisation d'une machine de musculation du haut du corps (pectoraux, dorsaux, épaules, bas, avant-bras) est donc considérablement réduit voire inexistant. En effet, la main n'étant plus prisonnière d'une structure de préhension rigide et fixe, la force qu'elle induit, quel que soit le mouvement effectué, s'oppose plus naturellement au système de résistance de la machine. En plus du fait que ce mouvement biologiquement naturel évite les micro traumatismes, en préservant la proprioceptivité de la chaîne articulaire qui travaille, la force de résistance élastique du ressort de la poignée permet d'optimiser l'effort (travail de la musculation ou de rééducation).The risk of microtrauma when using an upper body weight training machine (chest, back, shoulders, lower, forearm) is therefore considerably reduced or non-existent. Indeed, the hand is no longer trapped in a rigid and fixed gripping structure, the force it induces, regardless of the movement performed, more naturally opposes the resistance system of the machine. In addition to the fact that this biologically natural movement avoids micro traumas, preserving the proprioceptivity of the articular chain that works, the elastic resistance force of the spring of the handle makes it possible to optimize the effort (work of the bodybuilding or of reeducation ).

Il va de soi que la description détaillée de l'objet de l'Invention, donnée uniquement à titre d'illustration, ne constitue en aucune manière une limitation, les équivalents techniques étant également compris dans le champ de la présente invention.It goes without saying that the detailed description of the subject of the invention, given solely by way of illustration, does not constitute in no way a limitation, the technical equivalents also being within the scope of the present invention.

Ainsi, la section du ressort peut être carrée, ovale ou rectangulaire et ce dernier peut être en acier, en plastique ou en matériau composite.Thus, the section of the spring may be square, oval or rectangular and the latter may be steel, plastic or composite material.

La coquille peut être réalisée en matériau composite moulé, en métal fin embouti ou en alliage métallique.The shell can be made of molded composite material, stamped fine metal or metal alloy.

L'angle de rotation de la barre de préhension dans la coquille peut dépasser les 20°.The angle of rotation of the gripping bar in the shell may exceed 20 °.

Les rivets et vis peuvent être remplacés par d'autres moyens équivalents de fixation définitifs ou amovibles.The rivets and screws may be replaced by other equivalent means of permanent or removable fasteners.
