Description

La présente invention se rapporte au montage des bras de support d'un véhicule dans un pont élévateur. L'état de la technique le plus proche est vue en US-A-4,825,977.The present invention relates to the mounting of vehicle support arm in a lift. The closest prior art is seen in US-A-4,825,977.

L'invention vise des ponts élévateurs comprenant deux colonnes s'érigeant verticalement et le long desquelles sont mobiles des chariots reliés à des moyens pour commander leur élévation et leur descente jusqu'au sol, chaque chariot comportant, articulés sur deux axes verticaux, deux bras, ceux-ci pouvant occuper une position active dans laquelle ils s'étendent sous le véhicule à lever et une position inactive dans laquelle ils sont dégagés du véhicule.The invention relates to lifts comprising two columns erecting vertically and along which are movable trolleys connected to means to control their elevation and descent to floor, each carriage comprising, articulated on two axes vertical, two arms, these can occupy a position active in which they extend under the vehicle to get up and an inactive position in which they are clear of the vehicle.

Comme de tels ponts peuvent être utilisés pour des véhicules plus ou moins longs, les bras sont télescopiques afin que les extrémités libres qui sont pourvues de tampons destinés à coopérer avec des points d'appui prévus sous le véhicule, puissent être atteints. Il est de plus impératif que la longueur des bras en position repliée soit la plus courte possible faute de quoi il est impossible d'engager les bras sous le véhicule ceux-ci venant buter contre les roues de ce dernier.As such bridges can be used for more or less long vehicles, the arms are telescopic so that the free ends which are provided with buffers intended to cooperate with support points provided under the vehicle, can be reached. It is more imperative that the length of the arms in the folded position is the most short possible otherwise it is impossible to initiate arms under the vehicle these come up against the wheels of the latter.

Généralement, il est prévu deux bras longs et deux bras plus courts, les bras courts présentant trois éléments coulissant l'un dans l'autre. Une telle réalisation est complexe et chère et peu pratique.Generally, two long arms and two shorter arms, the short arms having three elements sliding one inside the other. Such an achievement is complex and expensive and impractical.

L'un des buts de la présente invention est de remédier à cet inconvénient.One of the aims of the present invention is to remedy this drawback.

Le montage, selon l'invention, est destiné aux ponts élévateurs comportant, au moins, deux colonnes le long de chacune desquelles est guidé un chariot relié à des moyens pour commander ses déplacements vers le haut pour soulever le véhicule et des moyens pour commander sa descente pour ramener le véhicule au sol, chaque chariot présentant, articulés sur des axes verticaux, deux bras télescopiques pourvus, à leur extrémité libre, d'un tampon destiné à coopérer avec un point d'appui prévu sous le véhicule, ledit montage étant caractérisé en ce que le chariot comporte deux platines horizontales parallèles, chaque platine comportant, sur sa face supérieure, deux pivots, chaque pivot de la face supérieure de l'une des platines étant aligné verticalement avec un pivot de l'autre platine, tandis que chaque bras comporte un élément tubulaire dont une extrémité est conformée pour présenter deux pattes percées, chacune, d'un trou, les trous étant alignés et destinés à coopérer avec les pivots. Grâce à cette disposition, on ménage, entre les platines, un espace dans lequel on peut insérer l'extrémité d'une rallonge montée coulissante dans l'élément tubulaire, de sorte que le bras peut être formé de deux éléments seulement dont la longueur, en position repliée, est suffisamment courte pour que les bras puissent pivoter librement.The assembly according to the invention is intended for bridges risers with at least two columns along each of which is guided a trolley connected to means to control its upward movements to lift the vehicle and means for controlling its descent for bring the vehicle back to the ground, each carriage presenting, articulated on vertical axes, two telescopic arms provided, at their free end, with a buffer intended for cooperate with a support point provided under the vehicle, said assembly being characterized in that the carriage has two parallel horizontal plates, each plate comprising, on its upper face, two pivots, each pivot of the upper face of one of the plates being aligned vertically with a pivot on the other platinum, while each arm has an element tubular, one end of which is shaped to present two lugs each pierced with a hole, the holes being aligned and intended to cooperate with the pivots. Thanks to this arrangement, a space is left between the plates in which you can insert the end of an extension sliding mounted in the tubular element, so that the arm can be formed of only two elements, the length, in the folded position, is short enough to the arms can pivot freely.

Suivant une caractéristique constructive, l'élément tubulaire de chaque bras a une section rectangulaire, l'une des extrémités étant découpée pour former l'une des pattes, tandis que la face opposée à celle pourvue de ladite patte comporte, rapportée et soudée, une barre formant l'autre patte.According to a constructive characteristic, the element tubular of each arm has a rectangular section, one ends being cut to form one of the legs, while the face opposite to that provided with said tab has, attached and welded, a bar forming the other paw.

Suivant encore une autre caractéristique constructive, la partie de la barre constituant l'autre patte est décalée en hauteur par rapport à la face correspondante de l'élément tubulaire, une plaque de renfort étant insérée et soudée entre la partie de la barre adjacente à la patte et la face correspondante dudit élément tubulaire.According to yet another characteristic constructive, the part of the bar constituting the other leg is offset in height from the face corresponding to the tubular element, a plate of reinforcement being inserted and welded between the part of the bar adjacent to the leg and the corresponding face of said tubular element.

De préférence, les deux platines sont reliées entre elles par une cloison médiane.Preferably, the two plates are connected between them by a middle partition.

Suivant encore une autre caractéristique, des moyens sont prévus pour bloquer les bras dans différentes positions angulaires.According to yet another characteristic, means are provided to lock the arms in different angular positions.

Enfin, suivant une dernière caractéristique constructive, la patte de la barre rapportée et soudée sur la face correspondante de l'élément tubulaire présente un secteur denté, tandis qu'entre les platines est montée coulissante contre l'action d'un ressort, une tige portant un verrou pourvu d'une denture destinée à coopérer avec le secteur denté, l'extrémité supérieure de la tige comportant une poignée pour commander le coulissement de ladite tige contre l'action du ressort afin de dégager la denture du secteur denté. Finally, according to a last characteristic constructive, the bar tab attached and welded to the corresponding face of the tubular element has a toothed sector, while between the plates is mounted sliding against the action of a spring, a rod carrying a lock provided with teeth intended to cooperate with the toothed sector, the upper end of the rod having a handle for controlling the sliding of said rod against the action of the spring in order to release the teeth from the toothed sector.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels :

  • Figure 1 est une vue en perspective éclatée montrant un chariot avec ses bras d'un pont élévateur.
  • Figure 2 montre le chariot de la figure 1 avec les bras montés.
  • Figure 3 est une vue en perspective d'un détail.
  • L'invention est plus particulièrement destinée aux ponts à deux colonnes et ici on a représenté l'aménagement de l'une des colonnes, l'autre étant identique.
    • The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings, in which:
  • Figure 1 is an exploded perspective view showing a carriage with its arms of a lift.
  • Figure 2 shows the cart of Figure 1 with the arms mounted.
  • Figure 3 is a perspective view of a detail.
  • The invention is more particularly intended for bridges with two columns and here is shown the arrangement of one of the columns, the other being identical.

    • La colonne est représentée en traits mixtes et porte la référence 1. Le long de cette colonne 1 est mobile un chariot 2 relié à des moyens pour commander son déplacement vertical, moyens connus qui ne sont pas représentés ici.The column is shown in phantom and carries reference 1. Along this column 1 is mobile a carriage 2 connected to means for controlling its movement vertical, known means which are not shown here.

    Le chariot 2 affecte, en section, la forme d'un U avec une âme 3 et deux joues 4, chaque joue comportant des organes 5 de guidage dans la colonne 1.The carriage 2 assumes, in section, the shape of a U with a core 3 and two cheeks 4, each cheek having guide members 5 in column 1.

    Entre les ailes 4 s'étend une entretoise 6 destiné à coopérer avec les organes de commande des déplacements verticaux du chariot 2.Between the wings 4 extends a spacer 6 intended to cooperate with the movement control members carriage vertical 2.

    A sa partie inférieure, les joues 4 sont solidaires d'une plaque 7 à partir de la partie médiane de laquelle s'étend une cloison 8. At its lower part, the cheeks 4 are integral of a plate 7 from the middle part of which extends a partition 8.

    A partir de la plaque 7 s'étendent deux platines 10 et 11 supportant, la première, deux pivots 13, 14 et, la seconde, deux pivots 15 et 16, les pivots 13 et 15 étant alignés et les pivots 14 et 16 également.From plate 7 extend two plates 10 and 11 supporting, the first, two pivots 13, 14 and, the second, two pivots 15 and 16, the pivots 13 and 15 being aligned and pivots 14 and 16 also.

    Le chariot 2 supporte deux bras 18 et 19. Chaque bras 18 et 19 est constitué d'un élément tubulaire 20 à section rectangulaire dont une extrémité est découpée pour former une patte 21 percée d'un trou 26. Sur une face 20a est soudée une barre 22 qui est pliée et prolongée pour former une patte 24 percée d'un trou 27, les trous 26 et 27 étant alignés. Entre la barre 22 et la face 2Ca est insérée et soudée une plaquette de renfort 23.The carriage 2 supports two arms 18 and 19. Each arm 18 and 19 consists of a tubular element 20 to rectangular section with one end cut out to form a tab 21 pierced with a hole 26. On a face 20a is welded a bar 22 which is folded and extended to form a tab 24 pierced with a hole 27, the holes 26 and 27 being aligned. Between bar 22 and face 2Ca is inserted and welded a reinforcing plate 23.

    Dans chaque élément tubulaire 20 est mobile une rallonge 30 comportant, à son extrémité libre, un tampon 31.In each tubular element 20 is movable a extension 30 comprising, at its free end, a buffer 31.

    Le bord de chaque patte 24 est découpé pour former un secteur denté 33.The edge of each tab 24 is cut to form a toothed sector 33.

    Les platines 10 et 11 sont percées de deux paires de trous 32 et 35, ces trous étant alignés et destinés à recevoir deux tiges 36 prolongées par une partie élastique 37 et terminées par une poignée 40 au voisinage de laquelle s'étend un verrou 38 présentant une denture 39 destinée à coopérer avec les secteurs dentés 33.The plates 10 and 11 are pierced with two pairs of holes 32 and 35, these holes being aligned and intended for receive two rods 36 extended by a part elastic 37 and terminated by a handle 40 in the vicinity from which extends a lock 38 having a toothing 39 intended to cooperate with the toothed sectors 33.

    Les pivots 13 et 15 sont engagés respectivement dans les trous 27 et 26 du bras 18 et les pivots 14 et 16 dans les trous 26 et 27 du bras 19. Une plaque de couverture 45 est fixée par une vis 41 se vissant dans un taraudage 42 de la cloison 8 et présente deux lumières 44 à travers lesquelles passent la partie des tiges 36 comprises entre les poignées 40 et les verrous 38.The pivots 13 and 15 are engaged respectively in the holes 27 and 26 of the arm 18 and the pivots 14 and 16 in the holes 26 and 27 of the arm 19. A cover plate 45 is fixed by a screw 41 screwed into a thread 42 of the partition 8 and has two lights 44 through which pass the part of the rods 36 between the handles 40 and the latches 38.

    Sur la tige 36 est monté un ressort de compression 37 dont une extrémité prend appui contre une butée 46, tandis que l'autre extrémité vient porter contre la face de la platine 10 tournée vers la platine 11, le verrou 38 étant solidaire d'une plaquette 47 appliquée élastiquement contre la face supérieure de la patte 24 et se trouvant bloqué angulairement par la plaque 7 et la cloison 8.On the rod 36 is mounted a spring of compression 37 one end of which bears against a stop 46, while the other end bears against the face of the plate 10 facing the plate 11, the latch 38 being integral with a plate 47 applied elastically against the upper face of the tab 24 and being blocked angularly by the plate 7 and the partition 8.

    Ainsi, la denture 39 de chaque verrou 38, en coopérant avec le secteur denté correspondant 33, assure le blocage angulaire de chaque bras 18 et 19.Thus, the teeth 39 of each latch 38, in cooperating with the corresponding toothed sector 33, ensures the angular locking of each arm 18 and 19.

    Si on désire déverrouiller les bras 18 et 19, il suffit de tirer sur les poignées 40 de manière que, contre l'action des ressorts 37, on éloigne les dentures 39 des secteurs 33.If you want to unlock the arms 18 and 19, it just pull the handles 40 so that, against the action of the springs 37, the teeth 39 are moved away from the sectors 33.

    Comme on le voit aux différentes figures, les rallonges 30 peuvent être relativement longues tout en pouvant s'insérer pratiquement dans la totalité des éléments tubulaires 20, du fait que les axes d'articulation des bras ne sont constitués que par des pivots. Ainsi, les rallonges 30 peuvent être repoussées jusqu'à une position extrême en arrière des pivots 15 et 16.As can be seen in the various figures, the extensions 30 can be relatively long while can be inserted into practically all of the tubular elements 20, due to the fact that the axes of articulation arms consist only of pivots. So the extensions 30 can be pushed back to a position far behind pivots 15 and 16.

    Chaque bras 20 peut comporter une poignée 49 facilitant sa manoeuvre. Ces poignées débordent latéralement de manière à faire saillie pour qu'elles puissent buter contre les jambes du mécanicien et éviter ainsi que celui-ci risque d'avoir les pieds coincés sous les bras lors de la descente du pont élévateur.Each arm 20 can include a handle 49 facilitating its operation. These handles extend laterally so as to protrude so that they can come up against against the mechanic's legs and avoid as well he may have his feet trapped under his arms when descending from the lift.

    Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the mode of realization which has just been described and represented. We may make many detailed changes without departing from the scope of the invention.
