Description
L'invention concerne les chariots de manutention emboîtables du type comportant quatre roulettes pivotantes disposées par paires aux extrémités avant et arrière du châssis du chariot et une cinquième roulette auxiliaire, non pivotante, disposée sous le plateau de chargement sensiblement dans l'axe longitudinal médian du chariot entre les roulettes avant et arrière. La fonction de cette cinquième roulette est de faciliter le déplacement en charge du chariot. Toutefois, la présence de cette cinquième roulette présente l'inconvénient de rendre difficile le déplacement en courbe des files de chariots lorsqu'ils sont emboîtés les uns dans les autres, car la ligne des cinquièmes roulettes forme to une sorte de rail virtuel pour la file de chariots. The invention relates to the interlocking handling trucks of the type comprising four pivoting casters arranged in pairs at the front and rear ends of the carriage frame and a fifth non-pivoting auxiliary caster disposed under the loading plate substantially in the median longitudinal axis of the trolley between the front and rear casters. The function of this fifth wheel is to facilitate the load movement of the truck. However, the presence of this fifth wheel has the disadvantage of making it difficult to move the rows of carriages when they are nested within one another, because the line of the fifth wheels forms a sort of virtual rail for the line. trolleys.
Pour remédier à cet inconvénient, il a été proposé de rendre la cinquième roulette relevable lors de l'emboîtement des chariots. To remedy this drawback, it has been proposed to make the fifth wheel liftable when nesting carts.
Is Dans ce but, le brevet EP 352 647 décrit un support de roulette auxiliaire monté à rotation sur la traverse avant du châssis et muni d'une tige de relevage destinée à s'engager dans un étrier fixé sous ladite traverse avant. Lors de l'emboîtement, la tige de relevage du chariot pénétrant s'engage dans l'étrier porté par la traverse avant du chariot receveur, ce qui provoque le soulèvement 20 du support de roulette par pivotement de ce dernier autour de l'axe de rotation horizontal par lequel il est monté sur le châssis. For this purpose, EP 352 647 discloses an auxiliary wheel support rotatably mounted on the front cross member of the frame and provided with a lifting rod for engaging in a stirrup fixed under said front cross member. Upon nesting, the lifting rod of the penetrating carriage engages in the stirrup carried by the front cross member of the receiving carriage, which causes the uprising of the roulette support 20 by pivoting the latter around the axis of horizontal rotation by which it is mounted on the chassis.
La présente invention vise à procurer d'autres moyens pour le relevage de la roulette auxiliaire, lesdits moyens étant aptes à former un sous-ensemble 25 facilement utilisable aussi bien pour équiper en première monte des chariots neufs que pour transformer des chariots existants dont la cinquième roulette est montée fixe par rapport au châssis. The present invention aims at providing other means for the lifting of the auxiliary wheel, said means being able to form a subset 25 easily used both for equipping new trucks in original equipment and to transform existing trolleys including the fifth roulette is fixed mounted relative to the chassis.
A cet effet, l'invention propose un support pour roulette auxiliaire caractérisé en 30 ce qu'il comporte des moyens de montage fixe sur le châssis d'un chariot de manutention emboîtable, et en ce qu'il comporte des moyens de rétractation, au moins partielle, de la roulette à l'intérieur du support. For this purpose, the invention proposes a support for an auxiliary wheel characterized in that it comprises means for fixed mounting on the chassis of an interlocking industrial truck, and in that it comprises retracting means, on less partial, roulette inside the support.
Selon un mode de réalisation préféré, le support est constitué par deux montants à l'intérieur desquels la roulette est montée coulissante sous l'action d'un levier porté par le support. According to a preferred embodiment, the support is constituted by two uprights within which the wheel is slidably mounted under the action of a lever carried by the support.
Les montants du support sont solidarisés à leur extrémité supérieure par une traverse ou entretoise et, sensiblement au milieu de leur longueur, par une entretoise en U ouverte en direction de l'extrémité inférieure libre des montants. L'extrémité libre de chaque montant présente au moins une lumière oblongue disposée sensiblement parallèlement à l'axe longitudinal des montants. The amounts of the support are secured at their upper end by a cross member or spacer and, substantially in the middle of their length, by a U-shaped spacer open towards the lower free end of the uprights. The free end of each upright has at least one oblong slot disposed substantially parallel to the longitudinal axis of the uprights.
L'entretoise centrale en U forme une cloche de réception d'une chape dans laquelle une roulette est montée à rotation libre. L'axe de rotation de la roulette est engagé dans les lumières oblongues présentes aux extrémités libres des montants du support. La chape porte sur sa face supérieure une queue qui s'engage dans un trou de l'entretoise en U. Un levier est monté pivotant entre les montants autour d'un axe horizontal. Le levier est muni d'un perçage pour le passage de l'extrémité libre de la queue de la chape sur laquelle il est maintenu par une goupille. Un ressort de compression est interposé autour de la queue entre la chape et l'entretoise en U. The central U-shaped spacer forms a receiving bell of a yoke in which a caster is mounted for free rotation. The axis of rotation of the wheel is engaged in the oblong slots present at the free ends of the amounts of the support. The yoke carries on its upper face a tail which engages in a hole of the U-shaped spacer. A lever is pivotally mounted between the uprights around a horizontal axis. The lever is provided with a bore for the passage of the free end of the tail of the yoke on which it is held by a pin. A compression spring is interposed around the tail between the yoke and the U-shaped spacer.
Le pivotement du levier autour de son axe de rotation provoque une traction sur la chape par l'intermédiaire de la queue et le coulissement de ladite chape le long des lumières oblongues du support à l'encontre du ressort de compression, ce qui rétracte au moins partiellement la roulette à l'intérieur des montants. The pivoting of the lever about its axis of rotation causes a traction on the yoke via the tail and the sliding of said yoke along the oblong slots of the support against the compression spring, which retracts at least partially the roulette inside the uprights.
Lorsque le support est fixé sur le châssis d'un chariot, il prend dans l'espace une position oblique vers le haut, la roulette étant en appui sur le sol. Lors de l'emboîtement, un poussoir porté par le chariot pénétrant fait pivoter le levier du support de roulette auxiliaire du chariot receveur, et par conséquent soulève cette roulette au-dessus du sol. When the support is fixed on the chassis of a carriage, it takes in space an oblique position upwards, the wheel being in support on the ground. During nesting, a pusher carried by the penetrating carriage rotates the lever of the auxiliary caster support of the receiving carriage, and therefore raises the caster above the ground.
D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, d'un mode de réalisation préféré en référence aux dessins annexés dans lesquels : La figure 1 est une vue schématique partielle en perspective d'un chariot de manutention emboîtable à cinq roulette muni d'un support de roulette auxiliaire selon l'invention, avec représentation du support de la roulette auxiliaire d'un deuxième chariot, non représenté, en début du processus d'emboîtement. Other features and advantages of the invention will emerge from the description which follows, of a preferred embodiment with reference to the accompanying drawings, in which: FIG. 1 is a partial schematic perspective view of a stackable handling truck with five wheels provided with an auxiliary wheel support according to the invention, with representation of the support of the auxiliary wheel of a second carriage, not shown, at the beginning of the nesting process.

La figure 3 est une vue en plan de dessus du chariot représenté sur les figures 1 et 2. Figure 3 is a top plan view of the carriage shown in Figures 1 and 2.
15 La figure 4 est une vue en perspective de dessus agrandie montrant plus en détail la constitution du support de roulette selon l'invention. Fig. 4 is an enlarged perspective view from above showing in more detail the constitution of the roulette support according to the invention.
Les figures 5a, 5b et 5c sont des vues de détail en coupe verticale illustrant le fonctionnement du support de roulette auxiliaire selon l'invention lors de 20 l'emboîtement de deux chariots. FIGS. 5a, 5b and 5c are vertical sectional detail views illustrating the operation of the auxiliary wheel support according to the invention when two carriages are interlocked.
Sur les figures 1 à 3 est représenté le châssis d'un chariot de manutention emboîtable, sans plateau de chargement, ni barre de manoeuvre, ni paniers. Figures 1 to 3 shows the frame of a nestable handling truck, without loading tray, maneuvering bar or baskets.
25 Le châssis est constitué par un tube coudé formant deux longerons latéraux 1 reliés par une traverse avant 2 et divergents en direction de l'arrière. Sur les extrémités arrière des longerons 1 sont fixés deux paires de montants verticaux 3 qui portent une barre de manoeuvre et un panier non représentés. Près de la traverse avant 2, une entretoise 4 délimite l'espace de réception des étriers 5 30 portant deux roulettes avant pivotantes 6. Deux roulettes arrière pivotantes 7 sont fixées à l'extrémité inférieure des montants 3. Le support 8 d'une roulette auxiliaire 9 est fixé sur l'entretoise 4 et les platines des roulettes avant 6. Le support 8' est celui d'un second chariot (non représenté) en approche d'emboîtement. The frame is constituted by a bent tube forming two side rails 1 connected by a front cross member 2 and diverging towards the rear. On the rear ends of the longitudinal members 1 are fixed two pairs of vertical uprights 3 which carry a maneuvering bar and a not shown basket. Near the front cross member 2, a spacer 4 defines the receiving space of the stirrups 30 carrying two pivoting front wheels 6. Two pivoting rear wheels 7 are attached to the lower end of the uprights 3. The support 8 of a wheel auxiliary 9 is fixed on the spacer 4 and the plates of the front rollers 6. The support 8 'is that of a second carriage (not shown) in nesting approach.
On voit que dans cet exemple de réalisation, le support 8 est fixé au châssis du 5 chariot en trois points, à savoir par une patte 10 sur l'entretoise 4 et par deux bras 11 sur les platines des roulettes avant 6. We see that in this embodiment, the support 8 is fixed to the chassis of the carriage in three points, namely by a tab 10 on the spacer 4 and by two arms 11 on the plates of the front wheels 6.
Le support 8 est formé par deux montants 12, solidarisés entre eux à leur extrémité supérieure, dirigée vers l'avant du chariot, par une patte 10 , formant t0 traverse ou entretoise, munie de perçages 13 pour le passage de vis de fixation, non représentées, dans l'entretoise 4 du châssis du chariot. Sensiblement en leur milieu, les montants 12 sont également reliés entre eux par une entretoise en U 14 dont l'ouverture est dirigée en direction de l'extrémité inférieure libre, dirigée vers l'arrière du chariot, des montants 12. 15 Chaque montant 12 présente à son extrémité libre au moins un, et dans cet exemple de réalisation deux lumières oblongues 15 orientées sensiblement parallèlement à l'axe longitudinal du montant. Sous l'entretoise en U 14, l'espace défini par les montants 12 accueille une chape 16 dans laquelle une roulette 9 est montée à rotation libre autour d'un axe horizontal dont les 20 extrémités sont engagées à coulissement libre dans une lumière 15 de chaque montant 12. Cette disposition permet au support de recevoir des roulettes de diamètre différent. Dans l'exemple de réalisation représenté la roulette 9 est montée sur un boulon traversant les lumières supérieures des montants 12 et les trous correspondants, non représentés des ailes de la chape 16. La chape 25 16 porte sur sa face supérieure une queue 17 qui traverse l'entretoise en U 14. Au- dessus de l'entretoise en U 14, les montants 12 portent un axe rotatif 18 solidaire d'un levier 19, engagé par un trou sur la queue 17. L'ensemble est maintenu par une goupille 20 traversant la queue 17. Entre l'entretoise 14 et la face supérieure de la chape 16, un ressort de compression 21 entoure la queue 30 17. De préférence, le levier 19 a , vu de profil, une forme en gradin. The support 8 is formed by two uprights 12, secured together at their upper end, directed towards the front of the carriage, by a tab 10, forming t0 cross or spacer, provided with holes 13 for the passage of fixing screws, no shown in the spacer 4 of the carriage frame. In their middle, the uprights 12 are also interconnected by a U-shaped spacer 14 whose opening is directed towards the lower free end, directed towards the rear of the carriage, amounts 12. 15 Each amount 12 has at its free end at least one, and in this embodiment embodiment two oblong slots 15 oriented substantially parallel to the longitudinal axis of the amount. Under the U-shaped spacer 14, the space defined by the uprights 12 accommodates a yoke 16 in which a roller 9 is mounted for free rotation about a horizontal axis whose ends are engaged with free sliding in a light 15 of each amount 12. This arrangement allows the support to receive wheels of different diameter. In the exemplary embodiment shown, the roller 9 is mounted on a bolt passing through the upper lumens of the uprights 12 and the corresponding holes, not shown, of the wings of the yoke 16. The yoke 25 bears on its upper face a tail 17 which runs through 14. Above the U-shaped spacer 14, the uprights 12 carry a rotary shaft 18 integral with a lever 19, engaged by a hole on the tail 17. The assembly is held by a pin By passing through the shank 17. Between the spacer 14 and the upper face of the yoke 16, a compression spring 21 surrounds the shank 17. Preferably, the lever 19 has, in profile, a stepped shape.
Près de leurs extrémités avant les bras de fixation 11 du support 8 portent un poussoir 22 qui, dans cet exemple est réalisé par un fil d'acier plié en forme d'étrier soudé sur les bras 11 et dont la pointe est dirigée vers l'avant du châssis du chariot. Near their ends before the attachment arms 11 of the support 8 carry a pusher 22 which, in this example is made by a bent steel wire bent on the arms 11 and whose tip is directed towards the front of the truck chassis.
Sur les figures 5a à 5c on voit que lors de l'emboîtement de deux chariots l'étrier 22 exerce sur le levier 19 une poussée qui provoque la rotation du levier 19 et une traction sur la chape 16, jusqu'à ce que la pointe du poussoir soit en position de butée engagée sous le gradin du levier 19. La roulette 9 est légèrement soulevée au-dessus du sol entre les longerons 12. L'engagement de l'extrémité du poussoir 22 sous le gradin du levier garantit que le levier reste io en position relevée quels que soient les mouvements relatifs des chariots dans une file en cours de déplacement. En raison de sa conception, le support de roulette auxiliaire selon l'invention constitue un sous-ensemble qui peut être fabriqué séparément et peut être monté très facilement aussi bien d'origine lors de la fabrication des chariots 15 qu'en remplacement de roulettes additionnelles fixes équipant un parc de chariots existants. In FIGS. 5a to 5c, it can be seen that during the engagement of two carriages the stirrup 22 exerts on the lever 19 a thrust which causes the lever 19 to rotate and pull on the clevis 16 until the spike the pusher is in the abutment position engaged under the step of the lever 19. The wheel 9 is raised slightly above the ground between the side members 12. The engagement of the end of the pusher 22 under the step of the lever ensures that the lever remains in the raised position regardless of the relative movements of the carriages in a queue during travel. Because of its design, the auxiliary caster support according to the invention constitutes a subassembly that can be manufactured separately and can be mounted very easily both originally in the manufacture of the carriages 15 and in replacement of additional casters. fixtures equipping a fleet of existing trolleys.
L'invention concerne aussi bien le support en tant que sous-ensemble que les chariots équipés de ce support. 20 The invention relates both to the support as a subassembly that the carriages equipped with this support. 20
