Abstract
Description
L'invention se rapporte à un montant télescopique de soutien du faîtage d'un véhicule couvert, disposé verticalement entre la plate-forme du véhicule et ledit faltage et permettant, par modification de sa longueur obtenue par coulissement mutuels puis verrouillage de ses éléments constitutifs, de lever ou d'abaisser le faîtage. The invention relates to a telescopic support upright of the ridge of a covered vehicle, arranged vertically between the platform of the vehicle and said faltage and allowing, by changing its length obtained by mutual sliding and locking of its constituent elements, lift or lower the ridge.
L'usage de montants de ce genre placés généralement aux quatre coins de la plate-forme d'un véhicule, permet d'en lever le faîtage a une plus grande hauteur, par exemple pour faciliter l'accès à la plate-forme lors d'un chargement (par l'arrière ou par un côté) en ouvrant au maximum les passages, puis de ramener le faltage en position normale. De tels montants télescopiques permettent également de rétablir l'horizontalité du faîtage lorsque la plate-forme présente une inclinaison de l'avant vers l'arrière ce qui peut se produire en particulier dans le cas des semiremorques. The use of such amounts generally placed at the four corners of the platform of a vehicle, allows to lift the ridge at a greater height, for example to facilitate access to the platform during a loading (from the rear or by a side) by opening the passages as much as possible, then to return the faltage to the normal position. Such telescopic uprights also make it possible to restore the horizontality of the ridge when the platform has a slope from front to rear, which can occur in particular in the case of semitrailers.
Il est connu d'équiper des véhicules eouverts de montants télescopiques avec simple verrouillage par engagement d'une broche transversalement dans -les éléments constitutifs de chacun des montants, à travers des trous alignés sur une partie de la hauteur des montants. Les manoeuvres sont alors très pénibles, car l'opérateur doit soulever par ses propres moyens le faltage à l'aplomb de chaque montant avant de averrouiller les éléments de celui-ci à la nouvelle longueur. It is known to equip vehicles with telescopic uprights with single locking by engaging a pin transversely in -the constituent elements of each of the uprights, through holes aligned on a portion of the height of the uprights. The maneuvers are then very difficult, because the operator must raise by his own means the faltage in line with each amount before unlocking the elements of it to the new length.
Pour faciliter les opérations, on a parfois associé aux montants télescopiques des vérins destinés à fournir la force de levage du faîtage. Mais de tels vérins exigent la présence de canalisations de fluide sous pression et surtout d'une source d'énergie, dont beaucoup de véhicules (par exemple les semi-remorques) sont dépourvus. To facilitate operations, it has sometimes associated with the telescopic uprights jacks intended to provide the lifting force of the ridge. But such cylinders require the presence of pressurized fluid lines and especially a source of energy, many vehicles (eg semi-trailers) are lacking.
Dans le but de faciliter les déplacements en hauteur du faîtage d'un véhicule couvert sans nécessiter la présence d'une source d'énergie à bord de celui-ci, l'invention a pour objet un montant télescopique caractérisé par le fait que ses éléments constitutifs sont reliés par un ressort dont ltaction tend à les faire coulisser mutuel- lement dans le sens d'une 2ugmentat on de la longueur du montant, la force de ce ressort étant voisine du poids de la charge que supporte le montant. In order to facilitate the movements of the height of the ridge of a covered vehicle without requiring the presence of an energy source onboard it, the invention relates to a telescopic post characterized by the fact that its elements The components are connected by a spring whose action tends to slide them mutually in the direction of a 2ugmentat on the length of the amount, the force of this spring being close to the weight of the load that supports the amount.
Le levage du faîtage, assisté par l'action du ressort précité qui compense ce poids, peut alrsise faire aisément sans effort. The lifting of the ridge, assisted by the action of the aforementioned spring which compensates for this weight, can easily be done without effort.
La force du ressort peut même etre choisie légèrement supérieure à ce poids ; dès iors, une fois les éléments du montant déverrouillés, le faltage remonte de lui-même, tandis qu'il suffit de le tirer vers le bas avec une force réduite pour le faire descendre. The spring force can even be chosen slightly higher than this weight; from then on, once the elements of the amount unlocked, the faltage goes back on its own, while it is enough to pull it down with a reduced force to make it go down.
Le ressort associé au montant est de préférence un ressort de compression. Dans une forme d'exécution avantageuse, il est constitué par un ressort à gaz (sorte de vérin dont le cylindre est rempli dtun gaz sous pression tendant à en faire sortir la tige). The spring associated with the upright is preferably a compression spring. In an advantageous embodiment, it is constituted by a gas spring (a sort of cylinder whose cylinder is filled with a pressurized gas tending to pull out the rod).
Le ressort précité p-eut être disposé soit à l'inbérieur, soit à l'exterleur du montant (dans le second cas, en juxtaposition le long de celui-ci). tar ailleurs, le ressort peut être disposé soit au pied, soit au sommet du montant. Le choix entre ces dispositions dépend de la structure particulière et de l'emplacement de chaque montant. The aforesaid spring may be placed either in the inside or outside of the upright (in the second case, in juxtaposition along it). elsewhere, the spring can be placed either at the foot or at the top of the upright. The choice between these provisions depends on the particular structure and location of each amount.
Le verrouillage des éléments constitutifs d'un montant selon l'invention s'effectue de préférence au moyen d'un dispositif monté sur l'élément inférieur et comportant un pêne "demi-tour" commandé par un organe de manoeuvre, tel qu'une poignée et susceptible de s'engager dans l'un des trous d'une série de trous prévus le long de l'élément supérieur. Le verrouillage desdits éléments se fait ainsi automatiquement dans la position mutuelle choisie parmi un certain nombre de positions déterminées. The locking elements constituting an amount according to the invention is preferably effected by means of a device mounted on the lower element and comprising a bolt "half-turn" controlled by an actuating member, such as a handle and engageable in one of the holes of a series of holes provided along the upper element. The locking of said elements is thus automatically in the mutual position selected from a number of specific positions.
L'invention a également pour objet un véhicule couvert équipé aux quatre coins de sa plate-forme de montants télescopiques tels que définis ci-dessus. Bien entendu, les montants intermédiaires ou ranchers disposés de chaque côté de la plate-forme doivent être de type télescopique ou démontable. The invention also relates to a covered vehicle equipped at the four corners of its platform telescopic amounts as defined above. Of course, the intermediate amounts or stanchions arranged on each side of the platform must be telescopic or removable type.
La description qui va suivre, en regard des dessins à titre d'exemplesnon limitatifs, permettra de bien comprendre comment la présente invention peut être mise en pratique. The following description, with reference to the drawings as non-limiting examples, will provide a good understanding of how the present invention can be practiced.
Les figures 1 et 2 représentent en perspective un montant télescopique selon l'invention, respectivement un montant arrière et un montant avant montés sur la plate-forme d'une semi-remorque. Figures 1 and 2 show in perspective a telescopic post according to the invention, respectively a rear upright and a front upright mounted on the platform of a semi-trailer.
On voit sur la figure 1 le montant arrière gauche d'une semi-remorque bâchée. Ce montant 1, porté par la plate-forme 2 de la semi-remorque dans le coin correspondant de celle-ci, soutient la barre d'angle 3 et l'arceau arrière 4 de faîtage sur lequel repose la bâche de couverture. We see in Figure 1 the left rear pillar of a tarpaulin semi-trailer. This amount 1, carried by the platform 2 of the semitrailer in the corresponding corner thereof, supports the corner bar 3 and the rear ridge 4 ridge on which the cover tarpaulin.
Le montant 1 est télescopique et comporte un élément inférieur la, constitue par un long. profilé dont le pied est fixé à l'ossature de la plate-forme 2, et un élément supérieur lb, également constitué par un long profilé, qui peut coulisser à l'intérieur de l'élément inférieur la dans un fourreau de guidage 5 que comporte ce dernier sur la majeure partie de sa hauteur.Cet élément coulissant lb, qui supporte à son sommet la barre d'angle 3, peut être solidarisé à l'élément inférieur la moyen d'un dispositif de verrouillage 6 fixé au bas de ce dernier et comportant un pêne "demi-tour" 7, en forme de broche, qui peut être, par manoeuvre d'une poignée 8, soit appliqué élastiquement contre une face de l'élément lb percée d'une série de trous de brochage 9 (pour le verrouillage), soit effacé à distance de cette face (pour le déverrouillage). The upright 1 is telescopic and has a lower element, constitutes a long. profile whose foot is fixed to the frame of the platform 2, and an upper element lb, also constituted by a long section, which can slide inside the lower element 1a in a guide sleeve 5 that comprises the latter over most of its height.This sliding element lb, which supports at its top the corner bar 3, can be secured to the lower element by means of a locking device 6 attached to the bottom of this last and having a pin-shaped "turn" latch 7, which can be operated by means of a handle 8, is elastically applied against a face of the element 1b pierced with a series of pin holes 9 (for locking), or cleared away from this side (for unlocking).
A sa partie inférieure, l'élément coulissant lb offre une longue encoche dans laquelle est logé un ressort à gaz 10 orienté suivant la direction du montant 1, prenant appui par le fond de son cylindre 10a sur la face terminale 11 de ladite encoche et par ltextrémité de sa tige lOb, dirigée vers le bas, sur une ferrure 12 solidaire de l'élé- ment la du montant. Ce ressort à gaz exerce sur l'élément lb une force qui tend à le faire monter en sortant de l'élé- ment la, cette force étant légèrement supérieure au poids du faîtage et de la bâche qui s'applique sur le montant 1. At its lower part, the sliding element 1b offers a long notch in which is housed a gas spring 10 oriented in the direction of the upright 1, supported by the bottom of its cylinder 10a on the end face 11 of said notch and by the extremity of its rod 10b, directed downwards, on a fitting 12 integral with the element 1a of the upright. This gas spring exerts on the element lb a force which tends to raise it out of the element 1a, this force being slightly greater than the weight of the ridge and the tarpaulin which is applied to the upright 1.
Lorsqu'on -désire lever le faîtage, on déverrouille, par manoeuvre du dispositif 8, l'élément coulissant lb. Celui-ci se déplace alors vers le haut sous la poussée du ressort à gaz 10, sans que l'opérateur ait à intervenir, jusqu'à ce que ce dernier ramène le dispositif 8 en position de verrouillage, le pêne 7 s'engageant alors dans le premier trou 9 qui se présente pour solidariser à nouveau les éléments la et lb du montant 1 dans la configuration de longueur accrue qula prise ce dernier. Le faîtage et la bâche se trouvent par suite levés d'une quantité correspondante dans le coin où se situe le montant 1 considéré. When one wishes to lift the ridge, unlocking, by operation of the device 8, the sliding member 1b. It then moves upward under the thrust of the gas spring 10, without the operator having to intervene, until the latter returns the device 8 in the locking position, the bolt 7 then engaging in the first hole 9 which is to reinforce the elements 1a and 1b of the upright 1 in the configuration of increased length that takes it. The ridge and the tarpaulin are consequently raised a corresponding amount in the corner where the amount 1 considered.
Pour abaisser le faîtage, on déverrouille de même l'élément coulissant lb. I1 suffit alors à l'opérateur de tirer vers le bas le faltage, par exemple en exerçant une traction sur une sangle de rappel attachée au faîtage ou à la bâche, avec une force minime puisque sensiblement égale à l'excès de force du ressort à gaz 10 par rapport au poids supporté par le montant 1, excès qui est peu important (et qui doit évidemment être inférieur au poids de l'opérateur). To lower the ridge, likewise unlocks the sliding member 1b. It is then enough for the operator to pull down the faltage, for example by exerting traction on a return strap attached to the ridge or the tarpaulin, with a minimum force since substantially equal to the excess force of the spring to gas 10 relative to the weight supported by the amount 1, excess is small (and must obviously be less than the weight of the operator).
Un montant télescopique assisté par ressort à gaz semblable à celui que l'on vient de décrire est prévu à chaque coin de la plate-forme 2 de la semi-remorque. A telescopic strut supported by a gas spring similar to that just described is provided at each corner of the platform 2 of the semitrailer.
Toutefois, une variante d'exécution peut être adoptée pour les montants 1' des coins avant, dont les éléments inférieurs l'a font corps avec la face avant 13 limitant antérieurement le volume utile du véhicule (figure 2). La différence de réalisation réside essentiellement en ceci que le ressort à gaz 10 est disposé ici à l'extérieur et au sommet du montant I' > son cylindre 10a prenant appui sur une ferrure 11' solidaire de l'élément inférieur l'a et sa tige lOb, tournée vers le haut, sur une ferrure -12' solidaire de l'élé- ment supérieur l'b. Le fonctionnement d'un montant 1' ainsi constitué est le même que celui du montant 1 précédemment décrit. However, an alternative embodiment can be adopted for the uprights 1 'of the front corners, the lower elements of which are integral with the front face 13 previously limiting the useful volume of the vehicle (Figure 2). The difference in embodiment lies essentially in the fact that the gas spring 10 is disposed here outside and at the top of the upright I '> its cylinder 10a bearing on a fitting 11' integral with the lower element the a and its rod lOb, turned upward, on a fitting -12 'secured to the upper element b. The operation of an amount 1 'thus constituted is the same as that of the amount 1 previously described.
