Description

EXTENSEUR LOMBAIRE NATUREL NATURAL LUMBAR EXTENDER
il est connu que,pour les vertèbres lombaires,il est bon de remplacer de temps en temps la compression par la traction,ceci en suspendant le bassin et les jambes,leurs poids propres mettant les vertèbres lombaires en extension. Ceci est très facile â réaliser en se suspendant par les mains ou par les bras â une barre fixe ou à un dessus de porte.par exemple;cette façon de se suspendre est très simple â réaliser mais elle a l'inconvénient majeur de faire travailler simultanément d'une façon désagréable et même malsaine, les articulations des épaules. Le but de la présente invention est un extenseur lombaire naturel pour la mise en extension des vertèbres lombaires par le propre poids des jambes et du bassin en évitant d'avoir une influence néfaste sur les articulations des épaules. A cet effet, l'extenseur lombaire naturel pince,à l'aide du poids propre de l'individu, la cage thoracique de l'individu à suspendre,entre deux demi-coquilles rigides qui sont articulées chacune sur un axe, ces deux axes étant à la fois sensiblement parallèles au sol et parallèles entre eux, un extenseur lombaire naturel est décrit dans le brevet US 3353532 du 21 Novembre 1967,cet extenseur lombaire comporte un cadre composé de deux colonnes réunies entre elles en haut et en bas paî. deè traverses,chaque colonne sert de support à l'articulation d'un bras, l'extrémité de chaque bras qui est situé entre les colonnes sert de support à l'articulation d'une demi-coquille de serrage pour la cage thoracique du patient.Cet extenseur lcanbaire a l'inconvénient d'avoir les axes de pivotement des coquilles de serrage situés au dessus des axes de pivotement des bras support,ceci nécessite d'avoir deux colonnes support avec tous les accessoirs que cela comporte et a pour conséquence que l'élasticité de la cage thoracique "Su patient, lors du serrage, diminue l'angle que font les bras support de coquille avec le plan horizontal perpendiculaire aux colonnes support. L'effort de serrage sur la cage thoracique du patient est égal à la force verticale (la moitié du poids du patient)divisée par la valeur de la tangente de l'angle que font les bras support de coquille avec le plan horizontal perpendiculaire aux colonnes support; théoriquement cet effort de serrage peut devenir infini¬ ment grand si la valeur de l'angle précité s'approche de 0°, pour un angle de 5° le serrage correspond déjà à 11,4 fois l'effort vertical. A cause de la diminution de l'angle précité par l'élasti- cité de la cage thoracique du patient, le réglage pour chaque patient doit être fait avec beaucoup de précautions et de savoir faire pour ne pas avoir un serrage trop fort qui, â la limite, pourrait écraser la cage thoracique, en conséquence, cet extenseur lombaire 5 ne peut pas être mis dans les mains de n'importe qui. Avec le but d'éliminer les inconvénients précités, l'extenseur lombaire naturel selon la présente invention est caractérisé par le fait que les deux bras support sur chacun desquels l'axe d'articulation de chaque coquille de serrage est fixé, sont reliés par une articula- 0 tion à une seule et unique colonne centrale qui est sensiblement perpendiculaire au sol, les deux bras support s'articulant chacun de part et d'autre.de la colonne centrale sensiblement dans un même plan, plan sensiblement parallèle à l'axe de la colonne centrale ,les bras support articulés étant en dessous du plan perpendiculaire 5 à la colonne centrale passant par les articulations des bras support sur la colonne centrale;les axes de pivotement des demi-coquilles de serrage se trouvent toujours au dessous des axes de pivotement des bras support et l'élasticité de la cage thoracique du patient augmente l'angle que font les bras support avec le plan horizontal 0 perpendiculaire à l'unique colonne centrale qui sert de support. Chacun des axes sur lequel chaque demi-coquille est articulée, est solidaire de son bras articulé par une pièce capable de coulisserit is known that, for the lumbar vertebrae, it is good to replace compression by traction from time to time, this by suspending the pelvis and the legs, their own weights putting the lumbar vertebrae in extension. This is very easy to achieve by hanging by the hands or arms on a fixed bar or above a door. For example; this way of hanging is very simple to carry out but it has the major disadvantage of making work simultaneously in an unpleasant and even unhealthy way, the shoulder joints. The object of the present invention is a natural lumbar extender for the extension of the lumbar vertebrae by the own weight of the legs and the pelvis while avoiding having a harmful influence on the shoulder joints. For this purpose, the natural lumbar extensor pinches, using the self weight of the individual, the rib cage of the individual to be suspended, between two rigid half-shells which are each articulated on an axis, these two axes being both substantially parallel to the ground and parallel to each other, a natural lumbar extender is described in US Patent 3353532 of November 21, 1967, this lumbar extender comprises a frame composed of two columns joined together at the top and bottom pai. from crosspieces, each column serves to support the articulation of an arm, the end of each arm which is located between the columns serves to support the articulation of a clamping half-shell for the patient's rib cage .This lcanbaire expander has the drawback of having the pivot axes of the clamping shells located above the pivot axes of the support arms, this requires having two support columns with all the accessories that this entails and has the consequence that the elasticity of the chest "Su patient, during tightening, decreases the angle made by the shell support arms with the horizontal plane perpendicular to the support columns. The effort of tightening on the chest of the patient is equal to the vertical force (half the patient's weight) divided by the value of the tangent of the angle made by the shell support arms with the horizontal plane perpendicular to the support columns; theoretically this tightening effort t become infinitely large if the value of the aforementioned angle approaches 0 °, for an angle of 5 ° the tightening already corresponds to 11.4 times the vertical force. Because of the reduction in the aforementioned angle by the elastic quoted from the patient's rib cage, the adjustment for each patient must be done with great care and know how to not have too strong a tightening which, ultimately, could crush the rib cage, consequently, this lumbar extensor 5 cannot be put in the hands of just anyone. With the aim of eliminating the aforementioned drawbacks, the natural lumbar extender according to the present invention is characterized in that the two support arms on each of which the articulation axis of each clamping shell is fixed, are connected by a articulation with a single central column which is substantially perpendicular to the ground, the two support arms each articulating on either side of the central column substantially in the same plane, plane substantially parallel to the axis of the central column, the articulated support arms being below the plane perpendicular to the central column passing through the articulations of the support arms on the central column; the pivot axes of the clamping half-shells are always below the axes of pivoting of the support arms and the elasticity of the patient's rib cage increases the angle that the support arms make with the horizontal plane 0 perpendicular to the single column central which serves as support. Each of the axes on which each half-shell is articulated, is secured to its articulated arm by a part capable of sliding

La colonne centrale,qui- supporte le poids de l'individu suspendu peut être soit simplement posée sur le sol en étant munie de pieds appropriés, soit être accrochée contre un mur ou être suspendue â la partie supérieure d'une porte,par exemple.Dans le cas de l'uti- lisation en trépied posé sur le sol,la colonne centrale forme un pied,les deux autres pieds sont dirigés vers l'avant en étant articulés sur un axe qui traverse la colonne centrale et la partie basse de ces pieds est directement ou indirectement reliée â la partie basse de la colonne centrale par un cable qui limite l'écar- tement des pieds par rapport â la colonne centrale; ceci permet de replier les pieds contre la colonne centrale et, après avoir, retiré les axes des demi-coquilles de leurs bras,de ranger l'appareil contre un mur ou dans un placard comme une planche à repasser ou- un aspirateur balais par exemple. Les deux demi-coquilles qui sont assimilables aux deux mains d'un adulte qui soulève un enfant en le serrant par le thorax,peuvent être solidaires chacune de leur axe en comportant un tube qui est emmanché sur l'axe et s'articule 5 dessus; elles peuvent également comporter chacune un profilé en forme de ϋ ouvert inversé,chaque U venant s'articuler sur son axe respectif en prenant appui dessus. Cette forme de réalisation permet de fixer préalablement les deux demi-coquilles rigides contre le thorax à l'aide d'une ceinture souple avec ou sans brete-_ ..

The central column, which supports the weight of the hanging individual can either be simply placed on the floor with suitable feet, or be hung against a wall or hung from the top of a door, for example. using a tripod placed on the ground, the central column forms a foot, the other two feet are directed forward by being articulated on an axis which crosses the central column and the lower part of these feet is directly or indirectly connected to the lower part of the central column by a cable which limits the spacing of the feet from the central column; this allows the feet to be folded against the central column and, after having removed the axes of the half the shells on your arms, store the unit against a wall or in a cupboard such as an ironing board or- a stick vacuum cleaner for example. The two half-shells which can be likened to the two hands of an adult who lifts a child by squeezing him by the thorax, can be secured each to their axis by comprising a tube which is fitted on the axis and is articulated 5 above ; they can also each comprise a profile in the form of an inverted open ϋ, each U coming to articulate on its respective axis by bearing on it.

La figure 8 est une vue de face de l'extenseur lombaire naturel de la figure 7. 1 est la colonne centrale, 2 et 3 sont les bras qui sont articulés en 4 et 5 dans le support 6 qui est solidaire de la colonne 1; ces bras 2 et 3 ont une section carrée. 7 et 8 sont les axes sur lesquels les demi-coquilles 9 et 10 sont articulées, 11 et 12 sont les pièces avec alésage carré qui supportent les axes 7 et 8 en pouvant couli- sser axialement sur les bras 2 et 3; les trous 13 dans la partie supérieure des bras 2 et 3 servent â fixer l'écartement des axes 7 et 8 à l'aide des goupilles 14 et 15. Les butées 16,17 limitent le basculement vers le haut des bras 2,3, les ressorts 18,19 appuient les bras 2,3 contre•les butées 16,17 lorsque l'appareil n'est pas en charge. La colonne 1 et les pieds 20,21 forment le trépied qui est posé sur le sol en se trouvant sous les axes' 7,8. La position des pieds 20,21 vers l'avant est fixée par le cable 22, cette posi- tion est telle que l'ensemble ne peut pas basculer lorsqu'un indi¬ vidu est suspendu entre lès axes 7 et 8. Les marches 23,24 sont rigidement reliées aux pieds 20,21 et servent â l'individu 25 pour se mettre en place sur les axes 7,8. Sur la figure 5, les demi- coquilles 9,10 sont munies de profilés en forme de U ouvert inver- se 26,27, de la ceinture 28 et des bretelles 29,30. Equipé de ses deux demi-coquilles 9,10 avec la ceinture 28 et les bretelles 29,30, l'individu 25 monte sur les marches 23,24 et,après un réglage pré¬ alable en largeur des axes 7,8, il place l'axe 7 dans le profilé 26 et l'axe 8 dans le profilé 27; il peut alors retirer ses pieds • des marches 23,24 et , en se laissant pendre sur les axes 7,8, sa cage thoracique est serrée et il est maintenu -suspendu en évitant d'être pendu par les dessous des bras, ce qui est le but recherché. Sur les figures 1 et 2 ainsi que â droite sur les figures 3 et 4, les demi-coquilles 9,10 sont solidaires de tubes 31,32 qui sont emmanchés sur les axes 7,8; dans ce cas la personne n'a pas besoin de la ceinture 28 ni des bretelles 29,30 et,après avoir réglé' 1* écartement entre les axes 7,8, vient,en montant sur les marches 23, 24, directement se placer entre les demi-coquilles 9,10 et se fait pincer en retirant ses pieds de la marche 23 ou 24, selon sa hauteur, cette variante est plus simple que pour la version de la figure 5 mais l'absence de ceinture nécessite une adaptation plus précise des demi-coquilles à la morphologie de l'individu. Il est évident que dans les deux cas, figure 5 ou figure 2, la partie intérieure des demi-coquilles 9,10 est tapissée de mousse à haut coefficient de frottement soit en caoutchouc soit en polyuréthane,cette mousse peut, préférablement,être munie d'un vernis souple anti-dérapant. En 33. et 34, les pieds 20,21 sont articulés par rapport â la colo¬ nne l,ceci afin de pouvoir replier l'appareil jusqu'à ce que les marches 23,24 viennent en contact avec la colonne 1; les goupilles 14,15 étant retirées, les pièces 11,12 avec les axes 7,8 peuvent être retirées des bras 2,3 et l'ensemble peut être rangé contre un mur ou dans un placard.Il est évident que ,sans rien changer au - caractère de l'invention, les articulations 4,5 des bras 2,3 peuvent être réunies en une seule articulation double ayant un axe commun, ceci est visible sur la figure 6 ou il n'y a qu'un seul axe 4 trav- ersant la colonne 1 pour les bras 2 et 3;sur cette figure les pièces 11,12 sont relativement longues pour avoir un bon guidage,chaque pièce 11,12 est munie d'une poulie 35,36 qui sert de guide pour les drisses 37,38 qui ont chacune un point fixe 39,40 respectivement sur les pièces 11,12; chaque bras 2,3 a, près de la colonne centrale l,une poulie 41,42 qui sert également de guidage aux drisses 37.38. Par le bout qui est opposé aux point fixes 39,40, il est possible de rapprocher les axes 7,8 des demi-coquilles 9,10 en tirant sur les drisses 37,38, ceci en effectuant un léger préserrage des demi- coquilles 9,10 contre la cage thoracique du patient; les graduations 43,44 sur les bras 2,3 permettent d'effectuer ce préserrage en ayant le patient bien centré pax rapport à la colonne centrale 1. Lorsque le préserrage,bien centré,est réalisé,le drisses 37,38 sont coincées dans les taquets 45,46 qui sont solidaires des bras 2,3; le patient peut alors être suspendu en étant serrer correctement entre lesFigure 8 is a front view of the natural lumbar extender of Figure 7. 1 is the central column, 2 and 3 are the arms which are articulated in 4 and 5 in the support 6 which is integral with the column 1; these arms 2 and 3 have a square section. 7 and 8 are the axes on which the half-shells 9 and 10 are articulated, 11 and 12 are the parts with square bore which support the axes 7 and 8 while being able to slide axially on the arms 2 and 3; the holes 13 in the upper part of the arms 2 and 3 serve to fix the spacing of the axes 7 and 8 using pins 14 and 15. The stops 16, 17 limit the tilting up of the arms 2.3, the springs 18,19 support the arms 2,3 against • the stops 16,17 when the device is not under load. Column 1 and feet 20,21 form the tripod which is placed on the ground being under the axes ' 7,8. The position of the feet 20, 21 towards the front is fixed by the cable 22, this position is such that the assembly cannot tilt when an individual is suspended between the axes 7 and 8. The steps 23 , 24 are rigidly connected to the feet 20,21 and are used by the individual 25 to set up on the axes 7,8. In FIG. 5, the half-shells 9, 10 are provided with inverted open U-shaped profiles 26, 27, the belt 28 and the straps 29, 30. Equipped with its two half-shells 9,10 with the belt 28 and the suspenders 29,30, the individual 25 climbs on the steps 23,24 and, after a prior adjustment in width of the axes 7,8, he places the axis 7 in the profile 26 and the axis 8 in the profile 27; he can then withdraw his feet • from the steps 23,24 and, by letting himself hang on the axes 7,8, his rib cage is tight and he is maintained -suspended by avoiding to be hanged by the underarms, which is the goal. In FIGS. 1 and 2 as well as on the right in FIGS. 3 and 4, the half-shells 9, 10 are integral with tubes 31, 32 which are fitted on the axes 7, 8; in this case the person does not need the belt 28 or the suspenders 29,30 and, after having adjusted '1 * spacing between the axes 7,8, comes, by climbing on the steps 23, 24, to be directly placed between the half-shells 9,10 and is pinched by removing its feet from the step 23 or 24, depending on its height, this variant is simpler than for the version in Figure 5 but the absence of a belt requires more adaptation specifies half-shells to the morphology of the individual. It is obvious that in both cases, Figure 5 or Figure 2, the inner part of the half-shells 9,10 is lined with high friction foam either rubber or polyurethane, this foam can, preferably, be provided with '' a flexible non-slip varnish. In 33. and 34, the feet 20, 21 are articulated with respect to the column 1, this in order to be able to fold the apparatus until the steps 23, 24 come into contact with the column 1; the pins 14.15 being removed, the parts 11.12 with the axes 7.8 can be removed from the arms 2.3 and the assembly can be stored against a wall or in a cupboard. It is obvious that, without changing anything au - character of the invention, the joints 4.5 of the arms 2.3 can be joined in a single double joint having a common axis, this is visible in Figure 6 or there is only one axis 4 crossing column 1 for arms 2 and 3; in this figure the parts 11,12 are relatively long to have good guidance, each part 11,12 is provided with a pulley 35,36 which serves as a guide for the halyards 37.38 which each have a fixed point 39.40 respectively on the parts 11.12; each arm 2,3 has, near the central column 1, a pulley 41,42 which also serves as a guide for the halyards 37.38. By the end which is opposite to the fixed points 39.40, it is possible to bring the axes 7.8 of the half-shells 9.10 closer together by pulling on the halyards 37.38, this by effecting a slight pre-tightening of the half-shells 9 , 10 against the patient's rib cage; the graduations 43,44 on the arms 2,3 allow this pre-tightening to be carried out with the patient well centered pax relative to the central column 1. When the pre-tightening, well centered, is carried out, the halyards 37,38 are trapped in the catches 45,46 which are integral with the arms 2,3; the patient can then be suspended by being properly squeezed between the

Si les demi-coquilles 9,10 sont placées sur les axes 7,8 de f çon à ce que le patient ait la colonne centrale 1 et les.bras articulés 2,3 en face de lui, le patient peut effectuer le préserrage seul et s'installer sans 1* aide de personne sur l'êlongateur lombaire naturel. Sur les figures 7 et 8 la colonne centrale 1 est munie,dans sa .partie supérieure, d'une traverse 47 avec les crochets 48,49 qui sont accrochés sur le barreau 50 de l'espalier 51 qui est lui même fixé au mur 52.Les cabinets de kinésithérapeute ou les salles de gymnastique ont toujours un espalier installé contre un mur. A sa partie inférieure,la colonne centrale 1 est munie d'une cale 53 qui prend appui sur les barreaux 54,55 de l'espalier 51; l'épaisseur de cette cale 53 est réglée soit pour donner une perpendicularité rigoureuse par rapport au sol soit pour donner un petit angle; dans certain cas un petit angle de la colonne centrale 1 par rapport au sol peut avoir une influ¬ ence bénéfique pour la colonne vertébrale du patient. -LLE DZ-RΞ ^ PA?

If the half-shells 9,10 are placed on the axes 7,8 so that the patient has the central column 1 and the articulated arms 2,3 in front of him, the patient can perform the pre-tightening alone and to install without the help of anyone on the natural lumbar extension. In FIGS. 7 and 8, the central column 1 is provided, in its upper part, with a cross member 47 with the hooks 48, 49 which are hung on the bar 50 of the wall bars 51 which is itself fixed to the wall 52 Physiotherapist offices or gymnasiums always have a wall bar installed against a wall. At its lower part, the central column 1 is provided with a wedge 53 which bears on the bars 54, 55 of the wall bar 51; the thickness of this wedge 53 is adjusted either to give a rigorous perpendicularity to the ground or to give a small angle; in some cases a small angle of the central column 1 with respect to the ground can have a beneficial influence on the spine of the patient.
