Abstract

A gravity-driven lumbar expander comprises two shafts (1, 2) with half-shells (3, 4) oscillating thereon. One end of each of the shafts (1, 2) is, directly or indirectly, rigidly fastened to a slide bar (5) supported by a bearing column (10), and at least one end of the slide bar (5) receives a slider (7) which is rotatably supported with respect to said slide bar (5), acts as a support for the end of one of said shafts (1, 2) and is connected via a traction mechanism to the stationary portion formed by the slide bar (5). This mechanism is preferably a rope of which one end is attached to the slider (7) while the other is attached to a winch barrel whose shaft (13) is, directly or indirectly, rigidly fastened to the slide bar (5). The slider (7) is automatically urged away from the bearing column (10) by a spring in the absence of a tensile load on the rope (19).

Description

El ongateur l ombai re par gravi té Shade elongator by gravity
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 à réaliser en se suspendant par les mains à une barre fixe ou à un dessus de porte, par exemple; cette façon de se suspendre est très simple à réaliser mais elle a. l'inconvénient majeur de faire travailler simultanément d'une façon 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 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 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 par des traverses, chaque colonne sert de support à l'articulation d'un bras, l'extrémité de chaque bras qui est située entre les colonnes, sert de support à l'articulation d'une demi-coquille de serrage pour la cage thoracique du patient Cet extenseur lombaire a l'inconvénient d'avoir les axes de pivotement des coquilles de serrage situés au dessus des axes de pivotement des bras support et a pour conséquence que l'élasticité de la cage thoracique du patient, lors du serrage, diminue les angles 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, donc 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 infiniment grand si la valeur de l'angle précité s'approche de 0°, pour un angle de 5e le serrage correspond déjà à 11,4 fois l'effort vertical. A cause de la diminution de l'angle précité par l'élasticité 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, à la limite, pourrait écraser la cage thoracique; en conséquence, cet extenseur lombaire ne peut 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 caractérise par le fait que le serrage de la cage thoracique du patient entre les deux demi-coquilles articulées n'est pas fonction du poids propre du patient mais peut être réglé par le patient lui même en agissant sur un mécanisme qui diminue l'écartement entre les deux demi-coquilles pour effectuer un serrage de la cage thoracique entre les deux demi-coquilles. A cet effet l'extenseur lombaire naturel selon l'invention comporte deux axes sur lesquels les demi-coquilles oscillent axes qui sont parallèles entre eux et dont une seule extrémité est directement ou indirectement solidaire d'une même poutre, cette poutre est une poutre 2 glissière qui est supportée par une colonne d'appui, au moins une extrémité de la poutre glissière reçoit un coulisseau qui est retenu en rotation par rapport à la glissière, ce coulisseau sert de support pour l'extrémité de l'un des axes sur lesquels les demi-coquilles oscillent le coulisseau est relié à la partie fixe par un mécanisme de traction qui peut être un filin relié à un tambour de treuil dont l'axe est directement ou indirectement solidaire de la poutre glissière, la rotation du tambour de treuil est réalisée par un mécanisme connu qui est actionné par le patient lui même; le coulisseau est automatiquement écarté de la colonne d'appui par un ressort lorsqu'il n'y a pas d'effort de traction sur le filin. Dans le cadre de l'invention il est également possible d'avoir un coulisseau à chaque extrémité de la poutre glissière, chaque coulisseau servant de support pour chacun des axes sur lesquels les demi-coquilles oscillent dans ce cas la colonne d'appui est située sensiblement au milieu de la poutre glissière et le tambour de treuil avec son mécanisme est également situé sensiblement au milieu de la poutre glissière, au dessus de la poutre d'appui; il y a alors deux filins, un pour chaque coulisseau, qui s'enroulent autour du tambour de treuil, dans ce cas, pour un serrage déterminé, la rotation à faire faire au tambour est moitié et l'effort à appliquer sur le tambour est double que dans le cas avec un axe fixe pour une demi-coquille et un seulcoulisseau pour l'autre demi-coquille. Avec deux coulisseaux l'appareil est plus compliqué mais il a l'avantage d'être symétrique. Lorsque les deux demi-coquilles sont reprochées l'une de l'autre, les coulisseaux compriment chacun un ressort, ceci permet d'écarter automatiquement les deux demi-coquilles dès que le mécanisme d'entrainement du treuil est désolidarisé du tambour de treuil. Les demi-coquilles comportent chacune, dans leur partie supérieure, un support pour la partie supérieure des bras, elles comportent sur toute leur hauteur, dans la partie située du coté du dos du patient un galbe qui empêche le patient de glisser hors des demi-coquilles vers l'arrière; elles comportent, en dessous de leur axe d'oscillation, dans la partie située vers l'avant du patient, une pièce galbée qui empêche le patient de glisser hors des demi-coquilles vers l'avant cette pièce galbée est coincée à l'aide d'une vis sur la demi-coquille en se servant d'une fente qui permet pour chaque patient, de régler la distance entre les galbes avant et arrière en fonction de l'épaisseur de sa cage thoracique. Les figures ci annexées représentent à titre indicatif et non limitatif des extenseurs lombaire naturel selon l'invention. La figure 1 est une vue latérale d'un extenseur lombaire naturel à deux coulisseaux suspendu à un espalier.It 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 do by hanging your hands from a fixed bar or above a door, for example; this way of hanging is very simple to achieve but it has. the major drawback of making the shoulder joints work simultaneously in an unhealthy manner. 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. To this end, the natural lumbar expander pinches 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 stent is described in US patent 3353532 of November 21, 1967, this lumbar stent includes a frame composed of two columns joined together at the top and bottom by 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 lumbar extender has the disadvantage of having the pivot axes of the clamping shells located above the pivot axes of the support arms and has the consequence that the elasticity of the patient's rib cage, during tightening, reduces the angles made by the shell support arms with the horizontal plane perpendicular to the support columns The clamping force on the patient's rib cage is equal to the vertical force, so half the patient's weight divided by the value of the tangent of the angle made by the rooster support arms uille with the horizontal plane perpendicular to the support columns; theoretically this clamping force can become infinitely large if the value of the aforementioned angle approaches 0 °, for an angle of 5 e the tightening already corresponds to 11.4 times the vertical force. Because of the reduction in the aforementioned angle by the elasticity of the patient's rib cage, the adjustment for each patient must be made with great care and know-how so as not to have too strong a tightening which, ultimately, could crush the rib cage; therefore, this lumbar extender 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 tightening of the patient's rib cage between the two articulated half-shells is not a function of the patient's own weight but can be adjusted by the patient himself by acting on a mechanism which reduces the spacing between the two half-shells to effect a tightening of the rib cage between the two half-shells. For this purpose the natural lumbar extender according to the invention comprises two axes on which the half-shells oscillate axes which are parallel to each other and of which only one end is directly or indirectly integral with the same beam, this beam is a beam 2 slide which is supported by a support column, at least one end of the slide beam receives a slide which is held in rotation relative to the slide, this slide serves as support for the end of one of the axes on which the half-shells oscillate the slide is connected to the fixed part by a traction mechanism which can be a rope connected to a winch drum whose axis is directly or indirectly secured to the slide beam, the rotation of the winch drum is carried out by a known mechanism which is actuated by the patient himself; the slide is automatically moved away from the support column by a spring when there is no tensile force on the rope. In the context of the invention it is also possible to have a slide at each end of the slide beam, each slide serving as support for each of the axes on which the half-shells oscillate in this case the support column is located substantially in the middle of the slide beam and the winch drum with its mechanism is also located substantially in the middle of the slide beam, above the support beam; there are then two ropes, one for each slide, which wrap around the winch drum, in this case, for a determined tightening, the rotation to be made to the drum is half and the force to be applied to the drum is double than in the case with a fixed axis for a half-shell and a single bush for the other half-shell. With two slides the device is more complicated but it has the advantage of being symmetrical. When the two half-shells are accused of each other, the sliders each compress a spring, this makes it possible to automatically separate the two half-shells as soon as the winch drive mechanism is detached from the winch drum. The half-shells each have, in their upper part, a support for the upper part of the arms, they comprise over their entire height, in the part located on the side of the patient's back, a curve which prevents the patient from sliding out of the shells backwards; they comprise, below their axis of oscillation, in the part situated towards the front of the patient, a curved part which prevents the patient from sliding out of the half-shells towards the front, this curved part is wedged using a screw on the half-shell using a slot which allows for each patient to adjust the distance between the front and rear curves depending on the thickness of his rib cage. The attached figures show by way of non-limiting illustration of natural lumbar extensors according to the invention.

Lorsque la roue dentée 15 tourne, vue sur les figures 3 et 6, dans le sens des aiguilles d'une montre, la réaction des dents sur les cliquets et vice versa, écarte chaque cliquet de la dent engagée, les ressorts 38,39 les réengageant automatiquement dans les dents suivantes. Lorsque la roue dentée 15 tourne, vue sur les figures 3 et 6, dans le sens inverse des aiguilles d'une montre, la réaction des dents sur les cliquets et vice versa, aide les ressorts 38,39 à pousser les cliquets 36,37 dans les creux de dent. En faisant tourner ' le levier 12 dans le sens des aiguilles d'une montre, l'on enroule les filins 18,19 sur le tambour 14 et le cliquet 36 reste engagé, par contre le cliquet 37 saute le nombre de dents correspondant à la rotation du levier 12. En faisant tourner le levier 12 dans le sens inverse des aiguilles d'une montre, la roue dentée 15 étant retenue en rotation par le cliquet 37, le cliquet 36 saute le nombre de dents correspondant à la rotation du levier 12. Le nombre de dents de la roue dentée par rapport au diamètre du tambour de treuil donne la finesse du réglage d'écartement des axes 1 et 2, pour cette raison il est préférable d'avoir au moins 20 dents à la roue dentée. Pour se libérer le patient doit simplement décharger le cliquet 37 en agissant sur le levier 12 puis désengager le cliquet 37 en agissant sur la partie 40 du cliquet 37, ensuite il bascule le levier 12 dans le sens inverse des aiguilles d'une montre sur les figures 3 et 6, ceci diminue le serrage du patient; lorsque la protubérance 41 du cliquet 37 rentre en contact avec la partie inférieure 42 du cliquet 36, le cliquet 36 est par l'action sur le levier 12, désengagé des dents de la roue dentée 15, le tambour 14 est alors complètement libre pour tourner par les efforts des ressorts 26,27 sur les filins 18,19. Sur la figure 6 le cliquet 36 a une poignée 45 qui permet de désenclancher le cliquet 36 des dents de la roue dentée 15 avant la mise en contact de la partie 42 du cliquet 36 avec la protubérance 41 du cliquet 37. Sur la figure 6 l'axe 1 est solidaire d'une charnière 21 dont la partie inférieure est directement solidaire de la poutre glissière 5 tandis que l'axe 2 est solidaire d'une charnière 21 dont la parie inférieure est solidaire du coulisseau 7; avec cette version, il n'y a pas besoin d'axe 25 avec les poulies 23,24, l'appareil est plus simple mais par contre le patient peut être légèrement décentré par rapport à la colonne support 10. Les tubes 46,47 sur lesquels les demi-coquilles 3,4 sont fixées, sont emmanchés sur les axes 1,2; ces tubes 46,47 ont vers l'avant chacun une fente 48 à laquelle correspond, sur les axes 1 et 2, un têton 49 qui est nettement plus petit que la fente 48, ceci permet de limiter l'oscillation des demi-coquilles 3,4 sur les axes 1,2. La partie arrière 50 des demi- coquilles 3,4 fait toute la hauteur des demi-coquilles et est galbée pour empêcher le dos du patient de glisser en dehors des demi-coquilles, cette partie 50 est monobloc avec la partie repose bras 51. La partie avant inférieure 52 des demi-coquilles est galbée vers l'avant pour empêcher le patient de glisser en dehors des demi-coquilles vers l'avant cette partie 52 se situe uniquement en dessous des axes 1,2, elle est indépendante et peut être déplacée vers l'avant ou vers l'arrière en faisant coulisser une vis avec écrou 53, solidaire de la partie 52, dans une fente 54 sensiblement horizontale qui se trouve dans la partie principale des demi-coquilles 3,4, ceci permet de régler la distance entre les galbes des parties 50 et 52 en fonction de l'épaisseur de la cage thoracique du patient II est évident que, sans rien changer au caractère de l'invention, il est possible de remplacer le treuil par un autre système mécanique, hydraulique ou pneumatique avec ou sans assistance électrique pour rapprocher les deux demi-coquilles et effectuer le serrage de la cage thoracique du patient 16.17 on the stops 30.31 of the slides 6.7, the other end of the cables 18.19 is positively fixed to the periphery of the winch drum 14 by the screw 32. The length of the cables 18.19 is such that , the springs 26,27 spreading the slides 6,7 freely the ropes 18,19 will be stretched by the force of the springs 26,27 and, at the end of the race, the slides 6,7 remain engaged on the slide beam 5. The stops 28,29 have openings suitable for the passage of ropes 18,19. The winch drum 14 with its toothed wheel 15 revolves freely on the axis 13 which is integral with the flanges 34,35 which form a body with the base 22, this as long as the pawls 36,37 are not engaged in the teeth of the toothed wheel 15. the springs 38, 39 push the pawls 36, 37, whose axes of rotation are 43 and 44, into the teeth of the toothed wheel 15. When the toothed wheel 15 turns, seen in FIGS. 3 and 6, clockwise, the reaction of the teeth on the pawls and vice versa, pushes each pawl away from the engaged tooth, the springs 38, 39 automatically reengaging them into the following teeth. When the toothed wheel 15 turns, seen in FIGS. 3 and 6, in the anticlockwise direction, the reaction of the teeth on the pawls and vice versa, helps the springs 38,39 to push the pawls 36,37 in the tooth hollows. By rotating the lever 12 clockwise, the cables 18,19 are wound on the drum 14 and the pawl 36 remains engaged, on the other hand the pawl 37 skips the number of teeth corresponding to the rotation of the lever 12. By rotating the lever 12 anticlockwise, the toothed wheel 15 being held in rotation by the pawl 37, the pawl 36 skips the number of teeth corresponding to the rotation of the lever 12 The number of teeth of the gear wheel relative to the diameter of the winch drum gives the fineness of the spacing adjustment of axes 1 and 2, for this reason it is preferable to have at least 20 teeth on the gear wheel. To free himself the patient must simply unload the pawl 37 by acting on the lever 12 and then disengage the pawl 37 by acting on the part 40 of the pawl 37, then he switches the lever 12 anticlockwise on the Figures 3 and 6, this reduces the patient's tightness; when the protuberance 41 of the pawl 37 comes into contact with the lower part 42 of the pawl 36, the pawl 36 is by the action on the lever 12, disengaged from the teeth of the toothed wheel 15, the drum 14 is then completely free to rotate by the forces of the springs 26,27 on the ropes 18,19. In FIG. 6 the pawl 36 has a handle 45 which makes it possible to disengage the pawl 36 from the teeth of the toothed wheel 15 before the part 42 of the pawl 36 comes into contact with the protuberance 41 of the pawl 37. In FIG. 6 l 'axis 1 is secured to a hinge 21 whose lower part is directly secured to the slide beam 5 while the axis 2 is secured to a hinge 21 whose lower wall is secured to the slide 7; with this version, there is no need for an axis 25 with the pulleys 23,24, the device is simpler but on the other hand the patient can be slightly off center with respect to the support column 10. The tubes 46,47 on which the half-shells 3,4 are fixed, are fitted on the axes 1,2; these tubes 46, 47 each have a slot 48 towards the front which corresponds, on the axes 1 and 2, to a stud 49 which is significantly smaller than the slot 48, this makes it possible to limit the oscillation of the half-shells 3 , 4 on axes 1,2. The rear part 50 of the half-shells 3,4 is the full height of the half-shells and is curved to prevent the patient's back from sliding out of the half-shells, this part 50 is in one piece with the arm rest part 51. The lower front part 52 of the half-shells is curved forward to prevent the patient from sliding out of the half-shells towards the front this part 52 is located only below the axes 1, 2, it is independent and can be moved forwards or backwards by sliding a screw with nut 53, integral with part 52, in a substantially horizontal slot 54 which is located in the main part of the half-shells 3,4, this makes it possible to adjust the distance between the curves of the parts 50 and 52 as a function of the thickness of the patient's rib cage It is obvious that, without changing the character of the invention, it is possible to replace the winch by another mechanical system, hydraulic or pneumatic with or without electric assistance to bring the two half-shells together and tighten the patient's rib cage
