Particulièrement, de telles barres sont télescopiques et présentent chacune deux parties qui peuvent être déplacées le long de leur plus grande dimension de façon à venir s'encastrer dans des perçages ou logements pratiqués dans la structure du véhicule utilitaire. Particulièrement, il est connu d'utiliser des barres de maintien par la direction verticale et/ou dans la direction horizontale. Dans un premier système, il est connu de former ainsi une forme de treillis composé par des barres principales de type télescopique et entre lesquels et dans la direction perpendiculaire aux barres principales sont disposées des barres auxiliaires, encastrées dans des logements prévus à cet effet en relation avec les barres principales. On connaît aussi des dispositions dans lesquelles se sont les mêmes types de barres qui sont utilisés dans les directions horizontale et verticale. Cependant, lorsque une barre de maintien de charge est étudiée, elle doit être conçue de manière à s'adapter à toute une gamme de dimensions de véhicules utilitaires et en particulier lorsque l'on désire que le même type de barres s'adapte à la fois dans la direction horizontale et dans la direction verticale, il faut à la fois que la barre soit capable de tenir un maintien maximal et d'accepter une gamme maximale d'allongements. Il en résulte que de telles barres sont à la fois lourdes et coûteuses.In the state of the art, it is known to removably insert and fix load-retaining bars in commercial vehicles of different shapes. In particular, such bars are telescopic and each have two parts that can be moved along their largest dimension so as to be embedded in holes or housings in the structure of the utility vehicle. In particular, it is known to use holding bars in the vertical direction and / or in the horizontal direction. In a first system, it is known to form a form of trellis composed of telescopic type main bars and between which and in the direction perpendicular to the main bars are arranged auxiliary bars, embedded in housings provided for this purpose in relation to with the main bars. Arrangements are also known in which the same types of bars are used which are used in the horizontal and vertical directions. However, when a load-holding bar is being studied, it must be designed to fit a range of utility vehicle dimensions and particularly when it is desired that the same type of bar be adapted to the In both the horizontal and vertical directions, both the bar must be able to hold a maximum hold and accept a maximum range of elongations. As a result, such bars are both heavy and expensive.
L'invention apporte un remède à ces inconvénients de l'état de la technique. En effet elle concerne une barre de maintien de charge pour véhicule utilitaire du genre télescopique et qui comporte :The invention provides a remedy for these disadvantages of the state of the art.

D'autres caractéristiques et avantages de la présente invention seront mieux compris à l'aide des discussions et des figures annexées parmi lesquelles :Other features and advantages of the present invention will be better understood by means of the discussions and the appended figures among which:
-- la figure 1 représente une vue partielle d'une barre verticale de maintien de charge en relation avec l'habitacle d'un véhicule utilitaire ; -- la figure 2 est un détail de la barre de la figure 1 et ;- Figure 1 shows a partial view of a vertical load bar in relation to the passenger compartment of a commercial vehicle; - Figure 2 is a detail of the bar of Figure 1 and;
-- la figure 3 représente une vue en coupe partielle d'une bague de manoeuvre de la barre de maintien de la figure 1.- Figure 3 shows a partial sectional view of an operating ring of the holding bar of Figure 1.
La figure 1 représente une vue partielle d'une barre verticale de maintien de charge en relation avec l'habitacle d'un véhicule utilitaire. On a représenté sous la référence 40 une partie de la structure de l'habitacle avec principalement la partie plane inférieure 41 -- 42 comprenant un plancher en bois 41 ainsi qu'une structure métallique nervurée 42, et la partie horizontale supérieure représentée par une traverse de pavillon 43. Le plancher en bois 41 et la traverse de pavillon sont munies d'une pluralité de perçages comme le perçage 44 sur la traverse de pavillon 43. Les perçages sont répartis de manière à permettre l'insertion verticale d'une barre verticale de maintien selon l'invention en des positions prédéterminées.Figure 1 shows a partial view of a vertical load bar in relation to the passenger compartment of a commercial vehicle. Is represented under the reference 40 a part of the structure of the passenger compartment with mainly the lower planar portion 41 - 42 comprising a wooden floor 41 and a ribbed metal structure 42, and the upper horizontal portion represented by a cross member 43. The wooden floor 41 and the roof cross member are provided with a plurality of holes such as the bore 44 on the roof crossbar 43. The holes are distributed so as to allow the vertical insertion of a vertical support bar according to the invention at predetermined positions.
La barre verticale de maintien est une barre télescopique référence 1 composée ici de une première et une seconde parties emboîtées, respectivement un tube principal 2 ainsi que une barre supérieure 3. Les première et seconde parties emboîtées, ici le tube 2 et la barre 3, sont sensiblement de forme cylindrique et destinées à coulisser l'une par rapport à l'autre le long de leur axe principal. Selon l'invention, la barre verticale est conçue de manière à servir simplement d'organe de maintien sans avoir à supporter une charge en appui longitudinal contrairement au cas d'un étai de soutien, dont la position duquel la barre verticale de l'invention se trouve placé pourtant. Au contraire, il est possible de réduire la résistance à la flexion de la barre verticale de maintien de l'invention jusqu'à respecter un seuil minimal de résistance à la flexion par une charge travaillant plutôt selon la normale à un plan vertical dans lequel est monté la barre verticale de maintien de l'invention. L'homme de métier saura déterminer le profil cylindrique convenable pour les première et seconde parties, ou plus si nécessaire, et qui sont ici constitués par le tube principal 2 et la barre supérieure 3. De même l'épaisseur des tôles dans lesquelles sont fabriqués au moins le tube principal et le cas échéant la barre supérieure 3 est calculée en fonction de ces caractéristiques de résistance mécanique. De plus il est possible d'envisager d'alléger la masse totale de la barre verticale de maintien de l'invention en réalisant des découpes dans les zones inactives de résistance mécanique.The vertical support bar is a reference telescopic bar 1 composed here of first and second nested parts, respectively a main tube 2 and an upper bar 3. The first and second nested parts, here the tube 2 and the bar 3, are substantially cylindrical in shape and intended to slide relative to each other along their main axis. According to the invention, the vertical bar is designed to serve simply as a holding member without having to bear a longitudinal bearing load unlike the case of a support strut, the position of which the vertical bar of the invention is located yet. On the contrary, it is possible to reduce the bending strength of the vertical holding bar of the invention until a minimum bending resistance threshold is met by a load which is working rather than the normal to a vertical plane in which is mounted the vertical bar of maintaining the invention. Those skilled in the art will be able to determine the suitable cylindrical profile for the first and second parts, or more if necessary, which are here constituted by the main tube 2 and the upper bar 3. Likewise the thickness of the sheets in which are manufactured at least the main tube and if necessary the upper bar 3 is calculated according to these mechanical strength characteristics. In addition it is possible to consider lightening the total mass of the vertical support bar of the invention by making cuts in the inactive areas of mechanical strength.
À la figure 1 , le tube principal 2 est surmonté à sa partie supérieure par une bague filetée intérieurement 5 qui vient en appui sur un bord supérieur du tube principal. La bague filetée intérieurement 5 est montée autour du filetage 4a d'une partie filetée 4a pratiquée sur une partie correspondante de la barre supérieure 3. De façon à être adaptée à différents modèles de véhicules dont la hauteur du pavillon par rapport au plancher peut différer d'un modèle à l'autre, il est prévu que la barre verticale de maintien de l'invention puisse présenter plusieurs parties filetées, comme les parties filetées 4a et 4b, à des hauteurs différentes le long de la barre supérieure 3. Ainsi, lorsque le véhicule utilitaire présente un pavillon à une grande hauteur au- dessus de son plancher, on utilise la barre verticale de maintien sur sa partie filetée 4b la plus haute tandis que pour un véhicule utilitaire ayant un pavillon à une hauteur plus réduite au-dessus de son plancher, on utilisera la même barre verticale de maintien sur sa partie filetée 4a la plus basse.In Figure 1, the main tube 2 is surmounted at its upper part by an internally threaded ring 5 which bears on an upper edge of the main tube. The internally threaded ring 5 is mounted around the thread 4a of a part threaded 4a made on a corresponding portion of the upper bar 3. To be adapted to different vehicle models whose height of the flag relative to the floor may differ from one model to another, it is expected that the vertical bar of the invention may have several threaded portions, such as the threaded portions 4a and 4b, at different heights along the upper bar 3. Thus, when the commercial vehicle has a flag at a great height above its floor, the vertical support bar is used on its threaded portion 4b the highest while for a commercial vehicle having a flag at a lower height above its floor, we will use the same vertical support bar on its threaded portion 4a the lowest.
Une fois montés l'un dans l'autre, la barre supérieure 3 et le tube principal 2, constituant les première et seconde parties principales de la barre télescopique formant la barre verticale de maintien de l'invention, présentent chacun une extrémité distale destinée à porter un moyen d'accrochage dans le pavillon 43 pour la barre supérieure 3 et dans le plancher 41 , 42 pour le tube principal 2. Selon l'invention, le moyen d'accrochage est essentiellement composé par un téton destiné à venir s'engager dans le perçage correspondant respectivement dans une traverse de pavillon ou sur un plancher bois posé sur le plancher proprement dit du véhicule utilitaire. Du fait de la hauteur réglable de la barre verticale de maintien, il est possible d'insérer la barre verticale de maintien dans un état relativement replié, par exemple en l'insérant par son pied dans un accrochage correspondant du plancher. Puis, en manipulant la bague en tant que moyen d'actionnement de la barre verticale de maintien, on étend la hauteur de la barre verticale de maintien de façon à ce que le téton associé au moyen d'accrochage supérieur de la barre supérieure 3 puisse pénétrer dans le perçage correspondant 44 de la traverse de pavillon 43. À la figure 2, on a représenté plus en détail un mode de réalisation de la barre verticale de maintien selon l'invention. À la figure 2, les mêmes éléments que ceux de la figure 1 portent les mêmes numéros de référence. Le pied ou partie inférieure du tube principal 2 reçoit un embout inférieur 21 destiné à servir de moyen d'accrochage avec un trou 8 pratiqué sur un plancher en bois 41 disposé sur le plancher métallique 42 du véhicule utilitaire dans lequel la barre verticale de maintien de l'invention est montée. L'embout inférieur 21 est composé d'une partie de centrage 21 dans le tube principal 2 qui se raccorde avec un épaulement 21c sur lequel vient le bout inférieur du tube principal 2. Enfin, l'embout inférieur comporte un téton 21b destiné à venir s'encastrer dans le perçage 8 du plancher bois 41.Once mounted one in the other, the upper bar 3 and the main tube 2, constituting the first and second main parts of the telescopic bar forming the vertical holding bar of the invention, each have a distal end intended for carry a hooking means in the roof 43 for the upper bar 3 and in the floor 41, 42 for the main pipe 2. According to the invention, the hooking means is essentially composed by a pin intended to engage in the corresponding hole respectively in a roof transom or on a wooden floor placed on the floor itself of the commercial vehicle. Due to the adjustable height of the vertical support bar, it is possible to insert the vertical support bar in a relatively folded state, for example by inserting it by its foot in a corresponding attachment of the floor. Then, by manipulating the ring as a means of actuating the vertical support bar, the height of the vertical support bar is extended so that the pin associated with the upper hooking means of the upper bar 3 can enter the corresponding bore 44 of the roof cross member 43. In Figure 2, there is shown in more detail an embodiment of the vertical support bar according to the invention. In Figure 2, the same elements as those of Figure 1 have the same reference numbers. The foot or lower part of the main tube 2 receives a lower nozzle 21 intended to serve as a hooking means with a hole 8 formed on a wooden floor 41 disposed on the metal floor 42 of the utility vehicle in which the vertical bar for holding the the invention is mounted. The lower nozzle 21 is composed of a centering portion 21 in the main tube 2 which connects with a shoulder 21c on which the bottom end of the main tube 2 comes. Finally, the lower end has a nipple 21b intended to come fit into the hole 8 of the wooden floor 41.
À l'intérieur du tube principal 2 est insérée la partie inférieure de la barre supérieure 3 dont le pied porte une bague de glissement ou de translation 47. Cette bague de glissement permet de guider le glissement relatif de la barre supérieure 3 dans le tube principal 2 sous l'action du moyen d'actionnement constitué par la bague filetée 5. À cet effet, la barre supérieure 3 comporte au moins une partie filetée 4a. La bague filetée 5 est disposée en haut du tube principal 2 sur lequel la partie basse de la bague filetée 5 s'appuie par l'intermédiaire d'une douille 22, par exemple en un matériau plastique inséré à force dans le diamètre intérieur du tube principal 2. Lorsque l'utilisateur fait tourner manuellement la bague filetée 5, la barre supérieure 3 est entraînée vers le haut ou vers le bas par la rotation de la partie filetée intérieure de la bague filetée 5 sur le filet 4a.Inside the main tube 2 is inserted the lower part of the upper bar 3 whose foot carries a sliding or translation ring 47. This sliding ring can guide the relative sliding of the upper bar 3 in the main tube 2 under the action of the actuating means constituted by the threaded ring 5. For this purpose, the upper bar 3 comprises at least one threaded portion 4a. The threaded ring 5 is disposed at the top of the main tube 2 on which the lower part of the threaded ring 5 is supported by means of a bushing 22, for example made of a plastic material inserted by force into the inside diameter of the tube 2. When the user manually rotates the threaded ring 5, the upper bar 3 is driven up or down by the rotation of the inner threaded portion of the threaded ring 5 on the thread 4a.
La partie supérieure de la barre supérieure 3 porte un pivot 45 sur lequel est monté une rondelle 11 en forme de cuvette et dont la face externe (supérieure au dessin) est destinée à recevoir une pièce 12 antivibratoire lorsque rondelle 11 et pièce 12 antivibratoire entrent en contact avec le profil du pavillon 43. Un rebord 46 est pratiqué sur le pourtour de la pièce 12 antivibratoire en matière souple permettant notamment d'absorber les vibrations transmises entre le pavillon 44 et le plancher 41,42 par la barre verticale de maintien 1.The upper part of the upper bar 3 carries a pivot 45 on which is mounted a washer 11 in the form of a bowl and whose outer face (greater than the drawing) is intended to receive an antivibration part 12 when washer 11 and antivibration part 12 come into contact with the profile of the roof 43. A flange 46 is made around the periphery of the room 12 antivibration flexible material allowing in particular to absorb vibrations transmitted between the roof 44 and the floor 41,42 by the vertical bar 1.
La rondelle en cuvette 11 présente une lumière axiale après à laquelle traverse un téton 31 solidaire du bout supérieur de la barre supérieur 3. Le téton 31 participe au moyen d'accord dans le perçage 44 représenté dans une traverse de pavillon 43 à la figure 1.The cup washer 11 has an axial lumen after which a stud 31 integral with the upper end of the upper bar 3 passes through. The stud 31 participates by means of tuning in the bore 44 shown in a roof crossmember 43 in FIG. .
À la figure 3, on a représenté une vue en coupe partielle et schématique d'une bague filetée 5 comme la bague filetée représentée à la figure 2. La coupe est réalisée à une hauteur de la bague filetée 5, sur un volet 7 qui peut tourner librement autour de l'axe central de révolution de la bague filetée 5 de manière à découvrir ou non une ouverture 51 à travers laquelle a été placé un ressort en forme de cliquet 6. Le cliquet 6 présente une partie d'appui 48 destinée à traverser la lumière ou ouverture 51 dans le volet 7 de la bague filetée 5. Lorsque le volet a été tourné de manière à découvrir la partie d'appui 48, le cliquet 6 peut librement se dégager d'encoches ou crantages 47,10 pratiqués sur la partie extérieure du filet de la partie filetée 4a de la barre supérieure 3. Dans cette position, la bague peut-être manipulée en rotation de façon à faire monter ou descendre la barre supérieure 3 à l'intérieur du tube principal 2. Inversement, lorsque le volet 7 est tourné manuellement par l'utilisateur de façon à recouvrir la partie d'appui 48 du cliquet 6, le cliquet 6 finit par s'engager par sa saillie 49 dans l'un des crantages 10 de sorte que la rotation relative de la bague filetée 5 et de la barre supérieure 3 est impossible, ce qui fixe la longueur de la barre télescopique constituée par la barre verticale de maintien de l'invention. Le cliquet 6 est complété par un repli 50 de la tôle métallique réalisée en un acier ressort.FIG. 3 shows a partial and schematic sectional view of a threaded ring 5, such as the threaded ring shown in FIG. 2. The section is made at a height of the threaded ring 5, on a flap 7 which can rotate freely about the central axis of revolution of the threaded ring 5 so as to discover or not an opening 51 through which has been placed a pawl-shaped spring 6. The pawl 6 has a bearing portion 48 for through the light or opening 51 in the flap 7 of the threaded ring 5. When the flap has been rotated so as to discover the bearing portion 48, the pawl 6 can freely disengage from notches or notches 47,10 practiced on the outer part of the thread of the threaded part 4a of the upper bar 3. In this position, the ring can be manipulated in rotation so as to raise or lower the upper bar 3 inside the main tube 2. Conversely, when the flap 7 is turned manually by the user so as to cover the bearing portion 48 of the pawl 6, the pawl 6 finally engages by its projection 49 in one of the notches 10 so that the relative rotation the threaded ring 5 and the upper bar 3 is impossible, which fixes the length of the telescopic bar constituted by the vertical bar of maintenance of the invention. The pawl 6 is completed by a fold 50 of the metal sheet made of a spring steel.
