Abstract

The vehicle has telescopic bars with an external rod (12) having a guiding ring (32) arranged at its proximal end in contact with an internal rod (14). An elastomer material toroid (16) is arranged between the bars to axially immobilize the rod with respect to the other rod along a determined length of one of the bars. A nut (18) is mounted inside the rod (12) and mounted freely in translation with respect to axis of the rods, where the nut is axially mounted with respect to the toroid. The bar is rotated with respect to the other bar so that the nut is displaced with respect to the toroid.

son espace de chargement" L'invention concerne un vehicule equipe de barres telescopiques d'amenagement de son espace de chargement et plus particulierement des barres telescopiques permettant de separer ou de maintenir des charges pendant le transport. Une telle barre comporte notamment : - une tige exterieure ; - une tige interieure montee coulissante axialement et io tournante par rapport a la tige exterieure en formant avec celle-ci une barre telescopique ; - des logements de maintien agences a I'interieur de la caisse du vehicule par paires opposees et destines a recevoir les extremites distales opposees de la barre telescopique ; is - un element elastique deformable agence entre les deux barres pour immobiliser axialement une tige par rapport a I'autre selon une longueur determinee de la barre telescopique ; - et un organe de corn mande monte tournant par rapport a au moins une des deux tiges pour provoquer la deformation de 20 ('element elastique ; Ce type d'amenagement interieur est en particulier destine a faciliter le transport de charges diverses et a prevenir tous dommages pouvant titre causes pendant le transport, notamment lorsque I'espace de chargement n'est pas completement rempli.  The invention relates to a vehicle equipped with telescopic bars for arranging its loading space and more particularly telescopic bars for separating or holding loads during transport, such a bar comprising in particular: a rod an inner shaft slidably mounted axially and rotatably with respect to the outer rod, forming therewith a telescopic bar; holding housings arranged inside the body of the vehicle in opposing pairs and intended to receive; the opposite distal ends of the telescopic bar is a deformable elastic element arranged between the two bars to axially immobilize one rod relative to the other along a determined length of the telescopic bar; ratio to at least one of the two rods for causing deformation of the elastic element; In particular, it is intended to facilitate the transport of various loads and to prevent any damage that may be caused during transport, especially when the loading space is not completely filled.

25 Plusieurs barres telescopiques et differents systemes de verrouillage et de fixation de telles barres sont deja connus et font ('objet de nombreux brevets. Le document US-A-5.281.063 presente des barres telescopiques pour fourgons du type pick-up. Cette barre telescopique s'etend transversalement dans la largeur 30 du fourgon et ses extremites distales sont revues dans des logements complementaires agences en regard dans les cloisons Iaterales du fourgon. Pour fixer la longueur d'une barre telescopique, i1 est connu de prevoir un dispositif de verrouillage situe, par exemple, 2 a la jonction des deux tiges. Un dispositif de verrouillage ou de blocage, dont un exemple est illustre dans le document US-A-4.324.502, comporte un element deformable de forme circulaire, positionne sur une piece excentree par rapport a ('axe de la barre telescopique et fixee a I'extremite libre proximale de la tige interieure, de maniere que, par rotation relative des deux tiges, une zone de ('element elastomere exerce une pression radiale suffisante contre rune des barres pour provoquer le verrouillage par friction. io Toutefois les deux systemes de verrouillage decrits et representes dans ces documents presentent des inconvenients. En premier lieu, la fabrication d'un tel systeme, comportant des pieces agencees sur des axes decales, est delicate et couteuse. D'autre part, si un tel systeme peut titre verrouille en appliquant is un faible couple en rotation, c'est egalement le cas pour le deverrouillage, ce qui constitue un risque certain de deverrouillage accidentel compte tenu des vibrations et des sollicitations que subissent de telles barres telescopiques dans un espace de chargement, notamment Tors du roulage.Several telescopic bars and various locking and fixing systems for such bars are already known and are the subject of numerous patents US-A-5,281,063 discloses telescopic bars for pick-up vans. telescopic extends transversely in the width of the van and its distal ends are reviewed in complementary housing agencies facing in the Icomal partitions of the van To fix the length of a telescopic bar, it is known to provide a locking device For example, at the junction of the two rods, a locking or locking device, an example of which is illustrated in the document US-A-4,324,502, comprises a deformable element of circular shape, positioned on an excenter part. relative to the axis of the telescopic bar and attached to the proximal free end of the inner shaft, so that, by relative rotation of the two rods, a zone of the elastomer element omere exerts sufficient radial pressure against one of the bars to cause frictional locking. However, the two locking systems described and represented in these documents have disadvantages. In the first place, the manufacture of such a system, comprising parts arranged on offset axes, is delicate and expensive. On the other hand, if such a system can lock by applying is a low torque in rotation, it is also the case for unlocking, which poses a certain risk of accidental unlocking taking into account the vibrations and stresses experienced by such telescopic bars in a loading space, especially when traveling.

20 II existe un reel besoin d'offrir plus d'efficacite pour le verrouillage de telles barres telescopiques afin que les charges diverses puissent titre positionnees en tous endroits du volume de chargement en toute securite. Pour repondre a ce besoin, la presente invention propose 25 un vehicule equipe d'un dispositif d'amenagement de son espace de chargement caracterise en ce que I'organe de commande est monte mobile axialement par rapport a ('element elastique et en ce que la rotation d'une barre par rapport a I'autre provoque un deplacement axial de I'organe de commande par rapport a 30 ('element elastique.

D'autres caracteristiques et avantages de ('invention 30 apparaitront a la lecture de la description detaillee qui suit pour la comprehension de laquelle on se reportera aux dessins annexes dans lesquels : - Ia figure 1 est une vue generate schematique en perspective de barres telescopiques horizontales et verticales 4 fixees en place dans I'espace de chargement d'un vehicule de type fourgon ; - Ia figure 2 est une vue schematique de la barre telescopique en utilisation ; - Ia figure 3 est une vue partielle en section axiale illustrant un premier mode de realisation d'un moyen de verrouillage de la Iongueur d'une barre telescopique ; - Ia figure 4 est une vue en coupe selon la ligne 4-4 representee a la figure 3 io - Ia figure 5 est une vue partielle en section axiale illustrant un deuxieme mode de realisation d'un moyen de verrouillage de la Iongueur de la barre telescopique ; - Ia figure 6 est une section d'un ecrou selon la ligne 66 representee a la figure 5 is - Ia figure 7 est une vue partielle en section axiale illustrant un troisieme mode de realisation du moyen de verrouillage de la Iongueur de la barre telescopique ; - Ia figure 8 est une vue partielle en section axiale illustrant un autre mode de realisation du moyen de verrouillage 20 de la Iongueur de la barre telescopique ; - Ia figure 9 est une section d'une bague selon la ligne 9-9 representee a la figure 8 - Ia figure 10 est une vue partielle en section axiale illustrant une extremite distale de la barre telescopique dans un 25 logement complementaire de la caisse du vehicule. Dans la description qui va suivre des elements identiques, analogues ou similaires seront designes par les memes chiffres de reference. Dans la description et dans les revendications, on adoptera 30 a titre non limitatif la terminologie verticale, transversale et longitudinale en reference au triedre represents figure 1, et axiale en reference a I'axe d'une barre telescopique. Le systeme, represents figure 1, est generalement constitue d'un lot de barres telescopiques 15 congues selon ('invention qui se positionnent dans des logements appropries 61 agences dans la structure de I'espace de chargement du vehicule 100. Ces logements 61 sont par exemple des trous existant s dans les membrures verticales 72 de la caisse, les traverses de pavilion 74 et des logements simples cress dans le plancher 76, de maniere a pouvoir positionner les barres telescopiques aussi bien horizontalement que verticalement. A cet effet, pour chaque positionnement, it existe une paire de trous ou logements 61 io opposes permettant a une barre telescopique 15 d'occuper une position verticale ou horizontale. Les barres 15 sont stockees longitudinalement, dans les zones non occupees habituellement par les charges dans I'espace de chargement du vehicule 100. Elles sont, par exemple, is accrochees sur des supports 70 de la structure interieure prevus a cet effet. Chaque barre telescopique 15, representee schematiquement a la figure 2, est constituee d'une tige exterieure 12, d'une tige interieure 14 et d'un systeme de verrouillage (non represents 20 a la figure 2) agence dans la zone de jonction des deux tiges, comportant les extremites proximales 12a et 14a. Les extremites libres distales 60 de cette barre 15 sont revues dans des logements 61. Selon un premier mode de realisation de ('invention, 25 illustre a la figure 3, le verrouillage en longueur de la barre telescopique 15 est assure par un systeme agence a I'interieur des deux tiges 12 et 14 formant la barre telescopique 15. L'utilisateur positionne les extremites libres distales 60 de la barre 15 dans les logements de caisse 61 choisis, positionnant la 30 barre a I'horizontale ou a la verticale. La tige interieure 14 comporte en son extremite libre proximale 14a un embout filets 20 a la base duquel est agence un tore en materiau elastomere 16. L'embout filets 20 est visse dans un ecrou 18 qui est monte, a I'interieur de la tige exterieure 12, libre en translation par rapport 6 a ('axe des tiges et fixe en rotation par rapport a la tige exterieure 12. On obtient la fonction d'anti-rotation de I'ecrou 18 par rapport a la tige 12 en ajoutant des protuberances 22, illustrees figure 4, situees a I'interieur de la tige exterieure 12, guidant I'ecrou 18 en coulissement ou par tout autre moyen adapte. Le tore elastomere 16 est monte solidaire de I'ecrou 18 de maniere a ne pas tourner sous ('effort, pour plus de facilites d'utilisation. io L'embout filete 20 comporte a son extremite un anneau 30 qui est fixe a son extremite ayant une fonction de butee afin que ('embout 20 ne puisse pas sortir de I'ecrou 18. Ainsi les deux tiges 12 et 14 ne peuvent pas titre desolidarisees. En tournant les deux tiges en rotation ('une par rapport a is I'autre autour de leur axe, ('embout filete 20 se visse dans I'ecrou 18 qui vient comprimer, par expansion radiale, le tore en materiau elastomere 16 contre la paroi interne de la tige exterieure 12 bloquant ainsi une tige par rapport a I'autre. La tige exterieure 12 est avantageusement equipee d'une 20 bague de guidage 32 agencee a son extremite proximale en contact avec la tige interieure 14, de maniere a assurer un bon maintien des deux tiges entre elles et diminuer les vibrations notamment lors du roulage. Un deuxieme mode de realisation de ('invention, illustre par 25 les figures 5 et 6, consiste a utiliser une piece tronconique permettant ainsi de diminuer le nombre de pieces utiles au verrouillage en longueur de la barre telescopique 15. Un embout tronconique filete 26, fixe a ('extremite proximale 14a de la tige interieure 14, se visse sur un ecrou tronconique fendu 24 (voir 30 figure 5). Cet ecrou tronconique 24 comporte des fentes 28 a son extremite opposee a ('embout 26 qui le divisent en"petales" 29. II est d'autre part, monte libre en coulissement axial dans la tige exterieure 12.There is a real need to provide more efficiency for the locking of such telescopic bars so that the various loads can be securely positioned in all places of the load volume. In order to meet this need, the present invention proposes a vehicle equipped with a device for arranging its loading space, characterized in that the control member is axially movable relative to the elastic element and in that the rotation of one bar relative to the other causes an axial displacement of the control member with respect to the elastic element According to other characteristics of the invention: the control member is a nut in the interior of the outer rod, mounted fixed in rotation and freely sliding relative to the axis of the bar, in that the proximal end 3 of the inner rod comprises a threaded end which is screwed into this nut and in that the deformable element is a torus of elastomeric material mounted between the threaded end and the nut so that by relative rotation of the two rods, the torus compresses immobilizes one rod relative to the other; control member is a threaded frustoconical tip fixed to a The proximal end of the inner rod, and in that the deformable element is a slotted frustoconical nut, free to slide in the outer rod so that by relative rotation of the two rods, the split frustoconical nut, by radial expansion immobilizes one rod relative to the other; - The control member is a tapped female ring forming a nut mounted outside the rods and screwed on a male threaded ring which is mounted fixed to the free end is proximal to the outer rod, and that (') deformable element is a torus made of elastomeric material arranged between the female ring and the male ring so that, by relative rotation of the two rings, the torus compresses immobilizes one rod relative to the other, the control member is a threaded female ring forming a nut mounted on the outside of the rods and screwed on a threaded male ring which is fixedly mounted at the proximal end of the outer rod and in that the deformable element is obtained by means of notches made at the proximal end of the outer shaft for elastic deformation of the proximal end of the outer shaft such that, by relative rotation of the two rings, the proximal end of the outer shaft radially clamps the inner shaft. Other features and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the accompanying drawings in which: FIG. 1 is a schematic general perspective view of horizontal and vertical telescopic bars; 4 fixed in place in the cargo area of a van-type vehicle; FIG. 2 is a schematic view of the telescopic bar in use; FIG. 3 is a partial view in axial section illustrating a first embodiment of a means for locking the length of a telescopic bar; FIG. 4 is a sectional view along the line 4-4 shown in FIG. 3; FIG. 5 is a partial view in axial section illustrating a second embodiment of a means for locking the length of the bar; telescopic; FIG. 6 is a section of a nut along the line 66 shown in FIG. 5; FIG. 7 is a partial view in axial section illustrating a third embodiment of the means for locking the length of the telescopic bar; FIG. 8 is a partial view in axial section illustrating another embodiment of the locking means 20 of the length of the telescopic bar; FIG. 9 is a section of a ring along line 9-9 shown in FIG. 8; FIG. 10 is a partial view in axial section illustrating a distal end of the telescopic bar in a complementary housing of the body of FIG. vehicle. In the following description identical, similar or similar elements will be designated by the same reference numerals. In the description and in the claims, the vertical, transverse and longitudinal terminology will be adopted in a nonlimiting manner with reference to the FIG. 1 representative, and axial in reference to the axis of a telescopic bar. The system, represented in FIG. 1, generally consists of a batch of telescopic bars 15 according to the invention which are positioned in suitable housings in the structure of the loading space of the vehicle 100. Examples of existing holes s in the vertical ribs 72 of the body, the cross members of pavilion 74 and single housing cress in the floor 76, so as to be able to position the telescopic bars both horizontally and vertically.For this purpose, for each positioning There is a pair of holes or housings 61 opposite to allow a telescopic bar 15 to occupy a vertical or horizontal position.The bars 15 are stored longitudinally in the areas not usually occupied by the loads in the loading space. Vehicle 100. They are, for example, hooked on supports 70 of the internal structure provided for this purpose Each telescopic bar 1 5, diagrammatically represented in FIG. 2, consists of an outer rod 12, an inner rod 14 and a locking system (not shown in FIG. 2) arranged in the junction zone of the two rods, having the proximal ends 12a and 14a. The distal free ends 60 of this bar 15 are examined in housings 61. According to a first embodiment of the invention, as illustrated in FIG. 3, the locking in length of the telescopic bar is ensured by a system which is provided by The inside of the two rods 12 and 14 forming the telescopic bar 15. The user positions the distal free ends 60 of the bar 15 in the housing slots 61 chosen, positioning the bar horizontally or vertically. internal rod 14 has at its proximal free end 14a a threaded end 20 at the base of which is a torus elastomeric material 16. The thread end 20 is screwed into a nut 18 which is mounted inside the outer rod 12, free in translation relative to 6a ('axis of the rods and fixed in rotation relative to the outer rod 12. The anti-rotation function of the nut 18 is obtained with respect to the rod 12 by adding protuberances 22, illustrated in Figure 4, if killed inside the outer rod 12, guiding the nut 18 in sliding or by any other suitable means. The elastomeric core 16 is mounted integral with the nut 18 so as not to rotate under stress (for greater ease of use) The threaded end 20 has at its end a ring 30 which is fixed at its end. having a stop function so that the end piece 20 can not come out of the nut 18. Thus the two rods 12 and 14 can not be separated by turning the two rods in rotation (one with respect to the other). other around their axis, the threaded end 20 is screwed into the nut 18 which compresses, by radial expansion, the torus made of elastomeric material 16 against the inner wall of the outer rod 12 thus blocking a rod relative to I ' The outer rod 12 is advantageously equipped with a guide ring 32 arranged at its proximal end in contact with the inner rod 14, so as to ensure a good maintenance of the two rods between them and to reduce the vibrations especially during the rolling A second embodiment of (inventi FIGS. 5 and 6 illustrate the use of a frustoconical piece, thus making it possible to reduce the number of pieces useful for locking the length of the telescopic bar 15. A threaded frustoconical endpiece 26 fixed to the proximal end 14a of the inner rod 14 is screwed on a split frustoconical nut 24 (see Figure 5). This frustoconical nut 24 has slots 28 at its end opposite to the tip 26 which divides it into "petals". On the other hand, it is free to slide axially in the outer rod 12.

7 En tournant les deux tiges 12 et 14 en rotation relative par rapport a leur axe, I'embout tronconique 26 vient se visser sur ('ecrou tronconique fendu 24. Au fur et a mesure du vissage, les "Wales" 29 de ('ecrou 24 s'ecartent radialement et se plaquent contre la paroi interne de la tige exterieure 12 bloquant ainsi une tige rapport a I'autre. De la meme maniere que pour le mode de realisation precedent, it est prevu un anneau 30 agence a I'extremite de I'embout tronconique filete 26, ayant une fonction de butee pour io empecher les deux tiges 12 et 14 de se desolidariser. Selon un troisieme mode de realisation de ('invention, illustre par la figure 7, le verrouillage en longueur de la barre telescopique 15 est realise a ('aide d'un plot de verrouillage 48 compose d'une bague ecrou 40 montee a I'exterieur des tiges 12 is et 14 qui est vissee sur une bague male 42, montee fixe a I'extremite proximale 12a de la tige exterieure 12. Un tore en materiau elastomere 44 est agence autour de la tige interieure 14, entre la bague ecrou 40 et la bague male 42. Par rotation relative des deux tiges par rapport a leur axe, la bague male 42 se visse 20 sur la bague ecrou 40 et comprime le tore 44 qui, par expansion radiale, entre en contact avec la tige interieure 14 et bloque la barre telescopique 15 a la longueur desiree. On peut avantageusement equiper chaque bague 42 et 44 d'un anneau elastomere 46 afin de faciliter la prehension et 25 ('utilisation du plot de verrouillage. Un quatrieme mode de realisation de ('invention, illustre aux figures 8 et 9, fait appel a ('utilisation d'un plot de verrouillage 48 sensiblement identique a celui decrit precedemment. Le plot 48 est forme d'une bague ecrou 40 montee a I'exterieur des tiges 30 12 et 14 et vissee sur une bague male 42 qui est montee fixe a I'extremite proximale 12a de la tige exterieure 12. Le trongon d'extremite proximale 12a de la tige exterieure 12 comporte des encoches ou rainures 50, reparties angulairement de maniere reguliere, qui le divisent en "Wales" 51 et qui permettent de 8 conferer une elasticite suffisante au trongon d'extremite proximale 14a de la tige exterieure 12. Par rotation relative des deux tiges par rapport a leur axe, la bague male 42 se visse sur la bague ecrou 40. Les "Wales" 51, en se rapprochant radialement, compriment la tige interieure 14 bloquant ainsi la barre telescopique 15 a la longueur desiree. Corn me le montre la figure 1, la barre telescopique possede egalement des plots de maintien 49, congus selon un systeme a vis possedant sensiblement les memes caracteristiques io que le plot decrit dans le troisieme mode de realisation. Ces plots de maintien 49 sont deplagables axialement sur rune ou I'autre des deux tiges afin de bloquer les charges en position dans I'espace de chargement. Les logements 61 destines a recevoir les extremites is distales 60 de la barre telescopique 15 (figure 10) sont de simples trous emboutis dans la tole ou bien integres dans le plancher bois de I'espace de chargement du vehicule. Afin d'eviter que les vibrations dues au roulage ne provoque une rotation intempestive de la barre 15 autour de son 20 axe et ainsi que la barre ne se deloge pendant le transport, une rondelle elastomere 62 est agencee a I'extremite distale 60 des tiges 12 et 14. Plus precisement, la rondelle elastomere 62 est traversee par I'extremite distale 60 et en position assemblee, elle coopere par frottement avec la tole des parois de la caisse.7 By rotating the two rods 12 and 14 in relative rotation with respect to their axis, the frustoconical tip 26 is screwed onto the truncated cone nut 24. As and when screwing, the "Wales" 29 of (' The nuts 24 extend radially and press against the inner wall of the outer rod 12 thus blocking one rod relative to the other, in the same way as for the preceding embodiment, a ring 30 is provided for the other. end of the threaded frustoconical end 26, having a stop function to prevent the two rods 12 and 14 from being separated, according to a third embodiment of the invention, illustrated in FIG. telescopic bar 15 is made with the aid of a locking stud 48 consists of a nut ring 40 mounted outside the rods 12 is and 14 which is screwed on a male ring 42, mounted fixed at the proximal end 12a of the outer rod 12. A torus of elastomeric material 44 is arranged around the a internal rod 14, between the nut ring 40 and the male ring 42. By relative rotation of the two rods relative to their axis, the male ring 42 is screwed 20 on the nut ring 40 and compresses the torus 44 which, by radial expansion , comes into contact with the inner rod 14 and locks the telescopic rod 15 to the desired length. Each ring 42 and 44 can advantageously be equipped with an elastomeric ring 46 in order to facilitate grasping and use of the locking pin 4. A fourth embodiment of the invention (illustrated in FIGS. The use of a locking stud 48 substantially identical to that previously described The stud 48 is in the form of a nut ring 40 mounted outside the rods 12 and 14 and screwed onto a male ring 42 which is fixedly mounted. at the proximal end 12a of the outer rod 12. The proximal end trimming 12a of the outer rod 12 has notches or grooves 50, distributed regularly angularly, which divide it into "Wales" 51 and which allow 8 provide a sufficient elasticity to the proximal end trongon 14a of the outer rod 12. By relative rotation of the two rods relative to their axis, the male ring 42 is screwed on the nut ring 40. The "Wales" 51, getting closer radially, compress the Inner rod 14 thus blocking the telescopic bar 15 to the desired length. As shown in Figure 1, the telescopic bar also has holding studs 49, designed according to a screw system having substantially the same characteristics io as the pad described in the third embodiment. These holding studs 49 are axially displaceable on one or the other of the two rods in order to block the loads in position in the loading space. The housings 61 intended to receive the distal ends 60 of the telescopic bar 15 (FIG. 10) are simple holes stamped into the sheet or integrated into the wooden floor of the loading space of the vehicle. In order to prevent the vibrations caused by rolling from inadvertently rotating the bar 15 about its axis and so that the bar does not dislodge during transport, an elastomeric washer 62 is provided at the distal end 60 of the rods. 12 and 14. More precisely, the elastomeric washer 62 is traversed by the distal end 60 and in the assembled position, it cooperates by friction with the sheet of the walls of the body.
