Description

La présente invention concerne un patin à roulettes en ligne décrit dans la préambule de la revendication 1.The present invention relates to a roller skate made of line described in the preamble of claim 1.

Du brevet US 5 405 156, on connaít déjà un tel patin à roulettes en ligne comprenant un châssis supérieur portant la chaussure et articulé dans sa partie médiane sur les extrémités de deux châssis inférieurs portant chacun deux roulettes. Un ressort, travaillant en compression, est disposé entre les extrémités libres des deux châssis et le châssis supérieur. Entre chacun de ces ressorts et l'articulation des châssis inférieurs est en outre monté un dispositif élastique auxiliaire de dureté réglable permettant de régler le degré d'absorption des chocs.From US Patent 5,405,156, there is already known such a roller skate in line comprising an upper chassis carrying the shoe and articulated in its middle part on the ends of two lower chassis each carrying two casters. A spring, working in compression, is arranged between the free ends of the two chassis and upper chassis. Between each of these springs and the articulation of the lower chassis is further mounted an auxiliary elastic device of adjustable hardness to adjust the degree shock absorption.

Du brevet GB 2 160 780 on connaít en outre un tel patin à deux roulettes en ligne monté aux extrémités d'un châssis inférieur au milieu duquel est articulé un châssis supérieur portant la chaussure. Ce patin est muni d'un frein sur la roulette arrière et de moyens élastiques s'opposant au basculement du châssis supérieur vers l'arrière. From patent GB 2 160 780 there is also known such a shoe two inline casters mounted at the ends of a lower chassis in the middle of which is articulated a upper frame carrying the shoe. This skate is fitted with a brake on the rear caster and means elastic to prevent tilting of the chassis upper back.

Dans la demande de brevet internationale WO 95/28209, il est en outre proposé de monter une chaussure sur un châssis par l'intermédiaire de ressorts placés à l'avant et à l'arrière de la chaussure.In international patent application WO 95/28209, it is also proposed to mount a shoe on a chassis by means of springs placed at the front and back of the shoe.

Toutes ces constructions ont pour inconvénient une instabilité de la chaussure rendant le patin difficile à diriger. Cette instabilité est due au basculement de la chaussure aussi bien vers l'avant que vers l'arrière autour d'un axe, déterminé ou non, situé sous la partie médiane de la chaussure.All of these constructions have the disadvantage of instability of the shoe making the skate difficult to lead. This instability is due to the tilting of the shoe both forwards and backwards around an axis, determined or not, located under the part middle of the shoe.

Du document WO95/08372 on connaít un patin sur lequel est articulée une pédale pour l'entraínement du patin par l'intermédiaire d'une roue dentée solidaire en rotation d'une manivelle sur laquelle s'appuie la pédale. Un ressort attaché à la roue dentée assure la rotation de la roue dentée lorsque la pédale remonte. Ce ressort n'a pas pour fonction d'amortir les chocs.From document WO95 / 08372 we know a shoe on which is articulated a pedal for skate training by means of a toothed wheel integral in rotation of a crank on which the pedal. A spring attached to the toothed wheel ensures the rotation of the toothed wheel when the pedal goes up. This spring does not have the function of absorbing shocks.

Du document US-A-3,749,413 on connaít un ski à roulettes pour l'entraínement au ski de fond, comportant un châssis sur lequel est articulée une fixation comprenant un châssis. Ce ski ne comporte pas de moyen d'amortissement.From document US-A-3,749,413 we know a ski at casters for cross-country skiing training, comprising a frame on which is articulated a fixing comprising a frame. This ski does not have depreciation means.

Du document US-A-5,232,231 on connaít un patin à roulettes comportant un châssis muni de roulettes et sur lequel est montée une chaussure munie d'une armature dans la région de la semelle s'étendant du talon au milieu de la semelle, cette armature étant articulée sur le châssis. La chaussure est par ailleurs fixée au châssis par sa semelle dans la région antérieure, de telle sorte que si la semelle de la chaussure était rigide, la chaussure serait rigidement fixée au châssis. La souplesse de la semelle autorise toutefois un pivotement de l'armature suffisante pour actionner un frein par un mécanisme multiplicateur de force. Ce patin ne comporte pas de moyen amortisseur de choc.Document US-A-5,232,231 we know a shoe casters comprising a frame fitted with casters and on which shoe is fitted with a frame in the sole region extending from the heel to the middle of the sole, this frame being articulated on the frame. The shoe is also fixed to the chassis by its sole in the anterior region, so that if the sole of the shoe was rigid, the shoe would be rigidly attached to the chassis. The flexibility of the sole, however, allows pivoting sufficient armature to apply a brake by a force multiplier mechanism. This skate does not have no shock absorber means.

La présente invention a pour but de réaliser un patin à châssis supérieur suspendu sans préjudice de la stabilité du patineur et à l'aptitude du patin à être dirigé.The object of the present invention is to produce a skate with upper chassis suspended without prejudice to stability of the skater and the ability of the skate to be steered.

Le patin à roulettes selon l'invention est caractérisé en ce que l'axe d'articulation du châssis supérieur sur le châssis inférieur est située dans la zone antérieure des châssis, à l'intérieur du périmètre d'un carré de 150 mm de côté, contenant la roulette avant et dont le côté antérieur vertical passe juste en avant de la roulette avant et le côté inférieur est le sol.The roller skate according to the invention is characterized in what the hinge pin of the upper chassis on the lower chassis is located in the anterior area of chassis, inside the perimeter of a 150 mm square side, containing the front caster and the side of which vertical anterior just in front of the wheel front and the bottom side is the ground.

Les moyens élastiques d'absorption des chocs peuvent être situés en arrière de l'articulation des châssis, sur cette articulation ou en avant de l'articulation.The elastic shock absorption means can be located behind the chassis joint, on this joint or in front of the joint.

Le patin est, de préférence, équipé de moyens de précontrainte réglables permettant de régler la dureté de la suspension, c'est-à-dire de l'amortissement. Ces moyens peuvent être des moyens amortisseurs auxiliaires ou non.The skate is preferably equipped with means of adjustable preload to adjust the hardness of suspension, that is, depreciation. These means may be auxiliary damping means or not.

La roulette avant peut être montée soit sur le châssis inférieur, soit sur le châssis supérieur. The front caster can be mounted either on the chassis lower, or on the upper chassis.

L'articulation du châssis supérieur dans sa partie antérieure, proche de l'extrémité de la chaussure, permet de conserver une bonne stabilité et une conduite aisée et précise du patin tout en permettant d'obtenir une très bonne absorption des chocs. La sensibilité aux chocs est en effet située dans la région du talon par lequel les chocs se transmettent à la jambe. Une suspension élastique à l'avant s'avère inutile.The articulation of the upper chassis in its part anterior, close to the end of the shoe, helps maintain good stability and handling easy and precise skating while allowing to obtain very good shock absorption. Sensitivity to shock is indeed located in the heel region by which shocks are transmitted to the leg. A elastic suspension at the front is useless.

La figure 19 est une vue en coupe verticale axiale des châssis du patin représenté à la figure 18.FIG. 19 is a view in axial vertical section of the skate frame shown in Figure 18.

Les figures 20, 21 et 22 représentent trois exemples d'intégration du châssis supérieur à la chaussure.Figures 20, 21 and 22 show three examples integration of the upper chassis with the shoe.

A la figure 1, on reconnaít une chaussure 1 montée sur un châssis supérieur 2 articulé autour d'un axe 3 sur un châssis inférieur 4 portant quatre roulettes en ligne 5, 6, 7, 8. L'axe 3 est situé légèrement en arrière et au dessus de l'axe de la roulette antérieure 5. Le châssis supérieur 2 est en outre supporté par un dispositif amortisseur 9 monté entre les châssis 2 et 4, entre les roulettes médianes 6 et 7, c'est-à-dire sous la partie médiane de la chaussure. Ce dispositif 9 est représenté en détail aux figures 2 et 3. En outre, comme ceci ressort de la figure 2, le châssis supérieur 2 présente un profil en U et le châssis inférieur 4 un profil en H qui vient s'emboíter dans le châssis supérieur 2, de telle sorte que ce châssis supérieur 2 est guidé latéralement sur le châssis inférieur 1. Le dispositif amortisseur 9 est constitué d'un manchon 10 en matériau élastomère dans lequel est engagée une douille 11 munie d'un filetage intérieur dans lequel est engagée une vis 12 dont la tête s'appuie sur la partie transversale du châssis inférieur 4. La douille 11 et la vis 12 permettent de précontraindre, en compression, le manchon 10 et par là de régler la dureté du dispositif amortisseur. On relève que le dispositif amortisseur 9 est abrité dans un logement formé par les châssis 2 et 4. Le dispositif amortisseur 9 pourrait être situé en un point différent, par exemple sous le talon ou près de l'axe 3.In Figure 1, we recognize a shoe 1 mounted on an upper frame 2 articulated around an axis 3 on a lower chassis 4 carrying four castors in line 5, 6, 7, 8. Axis 3 is located slightly in rear and above the axis of the front wheel 5. The upper frame 2 is further supported by a damping device 9 mounted between the chassis 2 and 4, between the middle rollers 6 and 7, that is to say under the middle of the shoe. This device 9 is shown in detail in Figures 2 and 3. In addition, as shown in Figure 2, the upper chassis 2 has a U-shaped profile and the lower chassis 4 a H profile which fits into the chassis upper 2, so that this upper chassis 2 is guided laterally on the lower chassis 1. The damping device 9 consists of a sleeve 10 made of elastomeric material in which is engaged a socket 11 provided with an internal thread in which a screw 12 is engaged, the head of which rests on the transverse part of the lower chassis 4. The socket 11 and the screw 12 make it possible to prestress, in compression, the sleeve 10 and thereby adjust the hardness of the damping device. We note that the damping device 9 is housed in a housing formed by chassis 2 and 4. The damping device 9 could be located at a different point, for example example under the heel or near axis 3.

Le carré A, situé dans un plan longitudinal, délimite la zone dans laquelle l'articulation 3 du châssis supérieur sur le châssis inférieur peut être située en conservant les avantages d'une articulation unique antérieure. Le carré A mesure 150 mm de côté. Son côté inférieur coïncide avec le sol et son côté antérieur vertical passe juste en avant de la roulette avant 5.Square A, located in a longitudinal plane, delimits the area in which the articulation 3 of the chassis upper on the lower chassis can be located in retaining the advantages of a single joint earlier. Square A measures 150 mm on a side. His side lower coincides with the ground and its anterior side vertical goes just in front of the front wheel 5.

Le patin représenté à la figure 4 ne diffère du patin représenté à la figure 1 que par le remplacement de l'axe simple 3 par une barre de torsion 13 et par l'utilisation d'un caoutchouc de moindre dureté pour le manchon 10 du dispositif 9. Dans ce cas, la suspension est principalement assurée par la barre de torsion 13, le dispositif 9 n'étant plus qu'un dispositif amortisseur permettant en outre de créer une précontrainte pour le réglage de la dureté de la suspension du châssis supérieur.The skate shown in Figure 4 does not differ from the skate shown in Figure 1 only by replacing single axis 3 by a torsion bar 13 and by the use of a lower hardness rubber for the sleeve 10 of the device 9. In this case, the suspension is mainly provided by the torsion bar 13, the device 9 being no more than a device shock absorber also allowing to create a preload for adjusting the hardness of the suspension of the upper chassis.

La barre de torsion pourrait être remplacée par un ressort de torsion.The torsion bar could be replaced by a torsion spring.

Le patin représenté aux figures 7 et 8 est également dérivé de la forme d'exécution de base représentée à la figure 1. Le moyen élastique principal est constitué ici d'un ressort 14 monté horizontalement dans un logement 15 ménagé dans le châssis inférieur 4 et travaillant en compression sous la pression d'un coulisseau 16 monté à l'extrémité d'une biellette 17 articulée par son autre extrémité en un point 18 sur le châssis supérieur 2. L'axe de la roulette 8 est également l'axe d'articulation de la biellette 17 sur le coulisseau 16, de telle sorte que la roulette 8 se déplace avec le coulisseau 16. Le dispositif 9 joue le même rôle que dans l'exécution représentée à la figure 4.The shoe shown in Figures 7 and 8 is also derived from the basic embodiment shown in the figure 1. The main elastic means consists here a spring 14 mounted horizontally in a housing 15 formed in the lower chassis 4 and working in compression under the pressure of a slide 16 mounted at the end of a link 17 articulated by its other end at a point 18 on the upper frame 2. The axis of the caster 8 is also the articulation axis of the link 17 on the slide 16, so that the caster 8 is moves with the slide 16. The device 9 plays the same role as in the execution represented in the figure 4.

Le logement 15 et le coulisseau 16 pourraient être situés en avant de l'axe de la roulette 8.The housing 15 and the slide 16 could be located in front of the axis of the caster 8.

La figure 9 représente une variante d'exécution de l'exécution représentée à la figure 7. Le ressort 14 est ici monté dans un logement 19 ménagé dans le châssis supérieur 2, légèrement en avant du talon. L'extrémité inférieure de la biellette 17 est articulée sur l'axe de la roulette postérieure 8.FIG. 9 represents an alternative embodiment of the execution shown in Figure 7. The spring 14 is here mounted in a housing 19 formed in the upper frame 2, slightly in front of the heel. The lower end of the link 17 is articulated on the axis of the rear caster 8.

Dans la forme d'exécution représentée à la figure 10, la chaussure 1 est fixée sur un châssis supérieur 20 dont la forme est pratiquement identique à celle du châssis 2. La roulette avant 5 est montée à l'extrémité de ce châssis 20 et le châssis inférieur 21, sur lequel le châssis supérieur 20 est articulé autour d'un axe simple 3 présente, à l'avant, une forme dégageant l'axe de la roulette 5. Le dispositif amortisseur 9 est identique à celui de l'exécution de base représentée à la figure 1.In the embodiment shown in Figure 10, shoe 1 is fixed to an upper frame 20 whose shape is practically identical to that of chassis 2. The front caster 5 is mounted at the end of this chassis 20 and the lower chassis 21, on which the upper chassis 20 is articulated around an axis simple 3 has, at the front, a shape clearing the axis of the caster 5. The damping device 9 is identical to that of the basic execution shown in Figure 1.

Cette exécution permet de passer de légères bosses d'un sol irrégulier avec plus de facilité et plus de confort.This execution allows to pass light bumps of a uneven ground with more ease and more comfort.

L'axe 3 pourrait, bien entendu, être équipé d'un ressort de torsion ou remplacé par une barre de torsion.Axis 3 could, of course, be equipped with a torsion spring or replaced by a bar torsion.

La forme d'exécution représentée à la figure 11 est dérivée de la forme d'exécution précédente. La roulette antérieure 5 est à nouveau montée sur le châssis supérieur 22 articulé sur un châssis inférieur 23 autour d'un axe simple 3. Ce châssis inférieur 23 présente un prolongement antérieur 23a s'étendant au-dessus de l'extrémité antérieure du châssis supérieur 22. Entre les extrémités des deux châssis est monté un ressort 24 travaillant en traction. Le dispositif 9 a à nouveau ici un rôle de réglage de la dureté de la suspension.The embodiment shown in Figure 11 is derived from the previous embodiment. Roulette front 5 is again mounted on the chassis upper 22 articulated on a lower chassis 23 around a single axis 3. This lower chassis 23 has an anterior extension 23a extending above from the front end of the upper chassis 22. Between the ends of the two chassis is mounted a spring 24 working in traction. The device 9 has to again here a role of adjusting the hardness of the suspension.

Les figures 12 et 13 représentent partiellement une septième forme d'exécution, dans laquelle le châssis supérieur est constitué de deux parties 25 et 26 intégrées à la semelle de la chaussure et présentant un profil en U dans lequel vient s'emboíter un châssis inférieur 27 également constitué d'un profilé en U. Les quatre roulettes 5 à 8 sont montées sur le châssis inférieur 27. La partie antérieure 26 du châssis supérieur est articulée sur le châssis inférieur 27 autour d'un axe 28 situé entre les deux roulettes antérieures 5 et 6. La partie postérieure 25 du châssis supérieur s'appuie sur le châssis inférieur 27 par un manchon 29 en matériau élastique relativement dur guidé par une tige 30. L'ébat des châssis est limité par une barrette transversale 31 fixée au châssis inférieur 27 et dont les extrémités sont engagées dans deux lumières verticales 32 ménagées dans le châssis supérieur 25.Figures 12 and 13 partially show a seventh embodiment, in which the chassis upper consists of two parts 25 and 26 integrated into the sole of the shoe and having a U-shaped profile into which a chassis fits lower 27 also made up of a U-shaped profile. four casters 5 to 8 are mounted on the chassis lower 27. The front part 26 of the chassis upper is articulated on the lower chassis 27 around an axis 28 located between the two rollers front 5 and 6. The rear part 25 of the chassis upper is supported on the lower frame 27 by a sleeve 29 of relatively hard elastic material guided by a rod 30. The framing of the chassis is limited by a cross bar 31 fixed to the lower frame 27 and whose ends are engaged in two lights vertical 32 formed in the upper frame 25.

La figure 14 représente une huitième forme d'exécution dérivée de l'exécution précédente. Le manchon élastique 29 est remplacé ici par un ressort-lame 33 s'étendant sous le châssis supérieur, passant au-dessus et devant l'axe d'articulation 28 et s'appuyant, par une partie coudée, contre deux portées 34 formées sur chacune des ailes du châssis inférieur 27, entre les roulettes antérieures 5 et 6. Le ressort-lame 33 est, de préférence, précontraint au montage.Figure 14 shows an eighth embodiment derived from the previous execution. The elastic sleeve 29 is replaced here by a leaf spring 33 extending under the upper chassis, passing above and in front the hinge pin 28 and supported by a part angled, against two spans 34 formed on each of wings of the lower chassis 27, between the rollers 5 and 6. The leaf spring 33 is, from preferably prestressed during assembly.

En variante, le ressort-lame 33 pourrait s'appuyer sur le châssis 27 entre les roulettes 6 et 7.Alternatively, the leaf spring 33 could rest on the frame 27 between the rollers 6 and 7.

Une neuvième forme d'exécution est représentée aux figures 15 et 16. La chaussure est à nouveau montée sur un châssis supérieur en deux parties 25 et 26 profilées en U. La partie antérieure 26 est articulée sur un châssis inférieur 35 présentant, sur la plus grande partie de sa longueur, un profil en H muni de passages pour les roulettes. Les quatre roulettes 5, 6, 7, 8 sont montées sur le châssis inférieur 35. L'axe d'articulation 28 des châssis est fixé dans le châssis inférieur 35 et ses extrémités sont engagées dans deux lumières horizontales 36 ménagées dans les faces latérales de la partie 26 du châssis supérieur. La partie postérieure 25 du châssis supérieur est munie de deux manetons latéraux 37 engagés librement et respectivement dans deux disques 38 en matériau à faible coefficient de frottement, par exemple en DELRIN (Marque déposée) montés rotativement dans des découpes circulaires des faces latérales du châssis 35. La suspension élastique est assurée par un dispositif analogue à celui de l'exécution de base. En l'absence de charge, les manetons 37 sont situés à environ 40° en arrière du point le plus haut des disques 38. Les lumières 36 autorisent le déplacement longitudinal du châssis supérieur et, par conséquent, la rotation des disques 38 sous charge. Ces lumières peuvent également limiter la rotation des disques 38, c'est-à-dire l'ébat vertical du châssis supérieur.A ninth embodiment is shown in Figures 15 and 16. The shoe is again mounted on an upper chassis in two profiled parts 25 and 26 U-shaped. The front part 26 is articulated on a lower chassis 35 having, on the largest part of its length, an H profile with passages for the casters. The four casters 5, 6, 7, 8 are mounted on the lower chassis 35. The axle hinge 28 of the chassis is fixed in the chassis lower 35 and its ends are engaged in two horizontal lights 36 arranged in the faces side of part 26 of the upper chassis. The rear part 25 of the upper chassis is provided with two lateral crank pins 37 freely engaged and respectively in two discs 38 of material to low coefficient of friction, for example DELRIN (Registered trademark) rotatably mounted in cutouts circular sides of the chassis 35. The elastic suspension is provided by a device analogous to that of the basic execution. Without load, the crank pins 37 are located at about 40 ° in rear of the highest point of the discs 38. The lights 36 allow the longitudinal displacement of the upper frame and therefore the rotation of 38 discs under load. These lights can also limit the rotation of the discs 38, that is to say the fram vertical of the upper chassis.

La figure 17 représente une variante d'exécution dans laquelle les disques 38 sont montés rotativement dans le châssis supérieur 25. Les disques 38 pourraient être associés à un ressort ou remplacé par un ressort. Dans ce cas le dispositif 9 assurerait la fonction de réglage de la dureté de l'amortissement.FIG. 17 represents an alternative embodiment in which the discs 38 are rotatably mounted in the upper chassis 25. The disks 38 could be associated with a spring or replaced by a spring. In in this case the device 9 would perform the function of adjustment of the damping hardness.

Le patin représenté aux figures 18 et 19 comprend un châssis supérieur 40 profilé en U articulé sur un châssis inférieur 41 autour d'un axe 42 situé à la verticale de l'axe de la deuxième roulette 6. Le châssis supérieur 40 est soutenu élastiquement entre la deuxième roulette 6 et la troisième roulette 7 par un dispositif amortisseur constitué d'un bloc 43 en matériau élastomère sur la face inférieure duquel est collée une plaque rigide 44 percée d'un trou dans lequel s'engage avec jeu l'extrémité 45a de diamètre réduit et lisse d'une vis 45 vissée dans un écrou 46 prenant appui sur le châssis inférieur 41, de telle manière que la plaque 44 s'appuie sur l'extrémité de la partie filetée de la vis 45 tout en pouvant basculer légèrement sur cette vis grâce au jeu. A l'avant, le châssis supérieur 40 s'appuie sur une butée 47 constituée d'une vis vissée dans un écrou 48 solidaire du châssis inférieur 41.The shoe shown in Figures 18 and 19 includes a upper frame 40 U-shaped articulated on a lower chassis 41 around an axis 42 located at the vertical axis of the second caster 6. The upper frame 40 is resiliently supported between the second roulette 6 and the third roulette 7 by one damping device consisting of a block 43 in elastomeric material on the underside of which is glued a rigid plate 44 pierced with a hole in which engages with play the end 45a in diameter reduced and smooth with a screw 45 screwed into a nut 46 bearing on the lower chassis 41, such so that the plate 44 rests on the end of the threaded part of screw 45 while being able to tilt slightly on this screw thanks to the play. At the front, the upper chassis 40 rests on a stop 47 consisting of a screw screwed into a nut 48 integral of the lower chassis 41.

L'actionnement de la vis 47 permet de régler l'inclinaison initiale du châssis supérieur relativement au châssis inférieur. La partie avant du châssis supérieur 40 étant en butée sur la butée 47, la vis 45 permet de précomprimer plus ou moins le bloc élastique 43, c'est-à-dire de modifier la dureté de la suspension. Une fenêtre oblique 49 dans le châssis supérieur 40 permet de visualiser la position de la plaque 44, donc la précontrainte du bloc 43. Des graduations permettent de visualiser cette précontrainte. En avant, deux jeux de graduations d'écarts différents 50 et 51 prévues respectivement sur le châssis supérieur et sur le châssis inférieur permettent, en faisant coïncider deux graduations, de régler le patin sur trois positions particulières au moyen de la vis 47 allant d'une position souple à une position dure. En outre, la compression du bloc 43 a pour effet d'emmagasiner de l'énergie moment où le patineur s'appuie sur le patin pour avancer, cette énergie étant restituée au moment où le patin quitte le sol.The actuation of screw 47 makes it possible to adjust the initial tilt of the upper chassis relative to the lower chassis. The front part of the upper chassis 40 being in abutment on abutment 47, the screw 45 allows the block to be more or less precompressed elastic 43, i.e. to modify the hardness of the suspension. An oblique window 49 in the frame upper 40 allows the position of the plate 44, therefore the prestressing of block 43. graduations allow to visualize this prestressing. In front, two sets of graduations different deviations 50 and 51 provided respectively on the upper chassis and on the lower chassis allow, by making coincide two graduations, of adjust the skate to three specific positions at by means of the screw 47 going from a flexible position to a hard position. In addition, the compression of block 43 has the effect of storing energy when the skater leans on the skate to advance, this energy being restored when the skate leaves the ground.

Les figures 20, 21 et 22 illustrent des exécutions dans lesquelles le châssis supérieur est intégré à la chaussure.Figures 20, 21 and 22 illustrate executions in which the upper chassis is integrated into the shoe.

Dans l'exécution selon la figure 20, le châssis supérieur 52 s'étend autour de l'arrière de la chaussure 1 et obliquement en direction de la roulette avant 5.

Dans la région du talon, les châssis 52 et 53 sont reliés entre eux par une zone élastique ou contenant un amortisseur.In the execution according to figure 20, the chassis upper 52 extends around the back of the shoe 1 and obliquely towards the caster before 5. It is further embedded in the shoe in constituting a reinforcement facilitating the catches downforce. Chassis 52 and 53 are articulated on the axis of the front caster 5. In the heel region, the chassis 52 and 53 are interconnected by a zone elastic or containing a shock absorber.

La forme d'exécution représentée à la figure 21 est dérivée de l'exécution représentée à la figure 12. Le châssis supérieur est constitué d'une partie antérieure 54 semblable à la partie 26 de la figure 12 et d'une partie postérieure 55 s'étendant autour de l'arrière de la chaussure en constituant un renforcement de la chaussure et, éventuellement, solidaire d'un collier 56 entourant la tige de la chaussure. Le châssis supérieur 54 est relié au châssis inférieur 57 par une partie élastique 58.The embodiment shown in Figure 21 is derived from the execution shown in figure 12. The upper frame consists of a front part 54 similar to part 26 of Figure 12 and a posterior part 55 extending around the rear of the shoe by constituting a reinforcement of the shoe and possibly attached to a collar 56 surrounding the upper of the shoe. The upper chassis 54 is connected to the lower chassis 57 by a part elastic 58.

Dans l'exécution selon la figure 22, le châssis supérieur 60 s'étend obliquement sur les côtés de la chaussure et forme un collier 61 muni de moyens de serrage 62. Le talon de la chaussure repose sur le châssis inférieur 63 qui présente une zone élastique 64.In the execution according to figure 22, the chassis upper 60 extends obliquely to the sides of the shoe and forms a collar 61 provided with means of tightening 62. The heel of the shoe rests on the lower frame 63 which has an elastic zone 64.
