Abstract

The lift has a carriage (2) which is movable along a column (1). Platforms (20) are provided to block/unblock the carriage in a given position and are pivotably mounted on the column. The platforms are spaced from each other by a specific distance in the height direction. Each platform is formed by a rack`s distal part (21) placed with respect to a rotation axis of the platform. The height of the rack is less than that of the platform (20) which is the closest to the ground of the platforms. A stop (23) prevents the part from descending down from the horizontal.

Description

La présente invention se rapporte à un pont élévateur comportant au moins une colonne, classiquement deux ou quatre colonnes, notamment verticales, le long desquelles sont mobiles des chariots. Chaque chariot est solidaire de moyens de support destinés à supporter directement ou par l'intermédiaire d'un plateau une charge que l'on souhaite élever, par exemple un véhicule automobile.The present invention relates to a lift having at least one column, typically two or four columns, including vertical, along which are movable trolleys. Each carriage is secured to support means for supporting directly or via a tray a load that is desired to raise, for example a motor vehicle.

On connaît déjà dans l'art antérieur des ponts élévateurs de ce genre. Ils comportent un système de sécurité antichute à crémaillère. Lorsque l'utilisateur souhaite faire descendre le pont, il doit d'abord déverrouiller ce système à crémaillère, puis commander la descente, le poste de commande se trouvant dans une zone spatiale où la sécurité est assurée.Elevator lifts of this type are already known in the prior art. They include a rack and pinion safety system. When the user wishes to lower the bridge, it must first unlock the rack system, then command the descent, the control station being in a space area where security is provided.

Dans ces systèmes connus, les crémaillères sont solidaires de la ou des colonnes et le dispositif formant verrou pour le verrouillage/déverrouillage est solidaire des chariots. Ces systèmes nécessitent un système de transmission compliqué pour la commande du verrou. En outre, les commandes doivent pouvoir être actionnées avec une efficacité totale quelle que soit la position verticale du chariot, ce qui est difficile et coûteux à réaliser.In these known systems, the racks are integral with the column or columns and the locking device for locking / unlocking is integral with the carriages. These systems require a complicated transmission system for latch control. In addition, the controls must be operable with total efficiency regardless of the vertical position of the carriage, which is difficult and expensive to achieve.

La présente invention vise un pont élévateur dont le mécanisme de verrouillage et de déverrouillage du plateau et la commande en montée/descente du plateau sont plus simples, et ce, avec une sécurité au moins aussi grande que dans le cas des ponts élévateurs de l'art antérieur. Suivant un perfectionnement de l'invention particulièrement intéressant, on peut obtenir un pont élévateur suivant l'invention qui est moins encombrant que les ponts élévateurs de l'art antérieur, notamment en hauteur. Au document US-B1-6.279.685 , il est décrit un pont suivant le préambule de la revendication 1. Suivant l'invention, un pont élévateur est tel que défini à la revendication 1, des perfectionnements étant définis aux sous-revendications.The present invention relates to a lift whose locking mechanism and unlocking the tray and the up / down control of the tray are simpler, and with a safety at least as great as in the case of the lift of the prior art. According to a development of the invention particularly interesting, one can obtain a lift according to the invention which is less bulky than the lifts of the prior art, especially in height. To the document US B1-6.279.685 , there is described a bridge according to the preamble of claim 1. According to the invention, a lift is as defined in claim 1, improvements being defined in the subclaims.

Suivant un mode de réalisation préféré de l'invention, les moyens formant taquet de blocage/déblocage sont constitués de taquets montés à pivotement sur la au moins une colonne et agencé de manière à pouvoir pivoter entre une première position dans laquelle ils bloquent le déplacement au moins vers le bas du chariot le long de la colonne et une deuxième position dans laquelle ils laissent le chariot se déplacer. Suivant un mode de réalisation préféré de l'invention, les taquets sont agencés de manière à, dans la première position de blocage, bloquer le déplacement du chariot uniquement dans le sens de la descente, le chariot pouvant se déplacer dans le sens de la montée même lorsque les taquets sont dans la première position de blocage. Suivant un perfectionnement de l'invention, les créneaux sont formés par des dents espacées les unes des autres.According to a preferred embodiment of the invention, the locking / unlocking cleat means consist of cleats pivotally mounted on the at least one column and arranged so as to be pivotable between a first position in which they block the movement at less down the carriage along the column and a second position in which they let the carriage move. According to a preferred embodiment of the invention, the catches are arranged in such a way that, in the first blocking position, the carriage can only be displaced in the direction of descent, the carriage being able to move in the upward direction. even when the cleats are in the first blocking position. According to an improvement of the invention, the slots are formed by teeth spaced apart from each other.

Suivant un autre perfectionnement, les créneaux sont formés par des trous, espacés les uns des autres, et éventuellement débouchant à la surface extérieure du chariot.According to another improvement, the slots are formed by holes, spaced from each other, and possibly opening to the outer surface of the carriage.

En prévoyant ainsi deux taquets à distance qui de préférence l'un après l'autre vont engrener les dents de la crémaillère du chariot mobile le long de la colonne, on peut faire monter haut le chariot mobile et donc le véhicule automobile, et ce, sans avoir à prévoir une hauteur de crémaillère ou de chariot mobile si haute qu'elle va prendre trop de place en hauteur, notamment dans le cas où la pièce dans laquelle se trouve le pont élévateur a un plafond. En effet, si la crémaillère n'a pas une grande dimension en hauteur, après avoir été bloquée par le premier taquet dans le sens de la descente, elle peut, dans le sens de la montée qui n'est pas bloqué, venir coopérer avec le deuxième taquet après être sortie de sa coopération avec le premier taquet. On peut ainsi monter le véhicule automobile d'une grande hauteur, sans avoir besoin d'un plafond élevé, et ce, avec une grande sécurité, telle que celle obtenue avec le système suivant l'invention à crémaillère solidaire du chariot et dispositif formant taquet solidaire de la colonne.By thus providing two remote cleats, preferably one after the other will mesh the teeth of the rack of the movable carriage along the column, can be raised high mobile carriage and therefore the motor vehicle, and, without having to provide a rack height or mobile carriage so high that it will take up too much height, especially in the case where the room in which the lift is located has a ceiling. Indeed, if the rack does not have a large dimension in height, after being blocked by the first stop in the direction of the descent, it can, in the direction of the climb which is not blocked, come to cooperate with the second cleat after being released from his cooperation with the first cleat. It is thus possible to mount the motor vehicle of a great height, without needing a high ceiling, and this, with a large safety, such as that obtained with the system according to the invention rack integral with the carriage and cleat device integral with the column.

Aux dessins, donnés uniquement à titre d'exemple, on décrit maintenant un mode de réalisation préféré de l'invention en se reportant aux dessins dans lesquels :

A la Figure 1, il est représenté un pont élévateur constitué de deux colonnes 1 verticales, qui n'est pas couvert par les revendications mais est utile à la compréhension de l'invention.To the Figure 1 , there is shown a lift consisting of two vertical columns 1, which is not covered by the claims but is useful for understanding the invention.

Un chariot 2 mobile est monté mobile le long de chaque colonne dans la direction en hauteur. Le chariot 2 mobile a, en section transversale, la forme d'un U ayant une âme 3 et deux joues 4, chaque joue comportant des organes 5 permettant son guidage le long de la colonne 1. Sur la surface extérieure, c'est-à-dire opposée à la concavité du U de l'âme 3, sont formées des dents 6, espacées les unes des autres de manière régulière sur toute la hauteur de l'âme 3. Chaque chariot est solidaire de deux bras de support 8 destinés à supporter la charge à élever, par exemple un véhicule automobile.A movable carriage 2 is movably mounted along each column in the height direction. The mobile carriage 2 has, in cross section, the shape of a U having a core 3 and two cheeks 4, each cheek having members 5 for guiding it along the column 1. On the outer surface, it is that is opposite to the concavity of the U of the core 3, teeth 6 are formed, spaced apart from each other in a regular manner over the entire height of the core 3. Each carriage is secured to two support arms 8 intended to to support the load to be raised, for example a motor vehicle.

Pour faire monter ou descendre le pont élévateur, par l'intermédiaire des chariots, il est prévu un dispositif 30 de commande de montée/descente du ou des chariots. Il peut s'agir, par exemple, d'un vérin électrique. Il peut également s'agir, de manière préférable, d'un vérin pneumatique ou hydraulique particulièrement silencieux.To raise or lower the lift, by means of the carriages, there is provided a device 30 for raising / lowering the carriages. It may be, for example, an electric cylinder. It can also it is preferable to use a particularly silent pneumatic or hydraulic cylinder.

Un taquet 20 est monté à pivotement sur la colonne 1. Ce taquet 20 est constitué d'une partie 21 distale se trouvant, par rapport à l'axe de rotation du taquet, du côté de la crémaillère et d'une partie 22 proximale. La partie 21 distale engrène les dents 6 de la crémaillère. Une butée 23 montée fixe sur la colonne est agencée de manière à empêcher la partie 21 distale du taquet 20 de descendre en dessous de l'horizontale. Un ressort 24 est monté en ayant ses extrémités reliées, d'une part, à la colonne 1 et, d'autre part, à la partie 22 proximale. Le ressort 24 tend à pousser la partie 22 proximale vers le haut en ayant tendance à maintenir le taquet 20 contre la butée 23.A latch 20 is pivotally mounted on the column 1. This latch 20 consists of a distal portion 21, relative to the axis of rotation of the latch, the side of the rack and a portion 22 proximal. The distal portion 21 meshes with the teeth 6 of the rack. A stop 23 fixedly mounted on the column is arranged to prevent the distal portion 21 of the cleat 20 from falling below the horizontal. A spring 24 is mounted having its ends connected, on the one hand, to the column 1 and, on the other hand, to the proximal portion 22. The spring 24 tends to push the proximal portion 22 upwards tending to hold the stop 20 against the abutment 23.

De manière avantageuse, on peut omettre le ressort, et prévoir, à la place, que la partie distale du taquet ait une masse supérieure à celle de la partie proximale, pour ainsi par pesanteur naturelle, obtenir la même fonction que celle fournie par le ressort.Advantageously, it is possible to omit the spring, and to provide, instead, that the distal portion of the cleat has a mass greater than that of the proximal portion, thus by natural gravity, to obtain the same function as that provided by the spring. .

La partie 21 distale du taquet 20 a une forme en biseau, en ayant une surface d'extrémité inférieure 25 inclinée vers le bas.The distal portion 21 of the cleat 20 has a bevelled shape, having a lower end surface 25 inclined downwardly.

Lorsque le dispositif 30 de commande, par exemple un vérin pneumatique ou hydraulique, fait monter le ou les chariots mobiles, la dent de la crémaillère, voisine du côté inférieur du taquet, vient porter contre la surface 25 inférieure inclinée et pousse le taquet contre la force du ressort 24 pour ainsi faire pivoter le taquet dans le sens qui fait s'abaisser la partie 22 proximale, de manière à permettre le passage de la dent. La dent suivante va ensuite, de la même manière, pousser le taquet pour passer également. Ainsi, dans le sens de la montée, le taquet 20 n'empêche pas le déplacement du chariot mobile.When the control device 30, for example a pneumatic or hydraulic cylinder, causes the mobile carriages to rise, the tooth of the rack, adjacent to the lower side of the catch, bears against the inclined lower surface and pushes the catch against the the force of the spring 24 to thereby rotate the latch in the direction that lowers the proximal portion 22, so as to allow the passage of the tooth. The next tooth will then, in the same way, push the cleat to pass as well. Thus, in the direction of the climb, the stop 20 does not prevent the movement of the movable carriage.

Dans le sens de la descente, au contraire, lorsque le taquet 20 est en position de blocage, c'est-à-dire en position sensiblement horizontale, la dent voisine du dessus ne peut pas passer le taquet et bute contre celui-ci. On obtient ainsi une sécurité contre une descente intempestive du chariot mobile, par exemple dans le cas d'une fuite de fluide d'actionnement dans le vérin hydraulique ou pneumatique. Le système 30 de commande du taquet 20 est représenté de manière schématique aux figures. Ce système 30, qui commande l'ensemble des taquets 20 en simultané, comporte un levier 31 qui, lorsqu'on l'actionne vers le haut, entraîne en rotation le taquet 20.In the direction of descent, on the contrary, when the cleat 20 is in the locked position, that is to say in substantially horizontal position, the tooth next to the top can not pass the stop and abuts against it. This provides a safety against inadvertent descent of the movable carriage, for example in the case of a leakage of actuating fluid in the hydraulic or pneumatic cylinder. The control system 30 of the catch 20 is shown schematically in the figures. This system 30, which controls the set of cleats 20 simultaneously, comprises a lever 31 which, when it is actuated upwards, rotates the cleat 20.

Lorsque l'on souhaite faire descendre le chariot mobile, on procède de la manière suivante. On actionne le dispositif 30 de commande de montée/descente du ou des chariots mobiles pour les faire se déplacer légèrement vers le haut, en créant un petit jeu entre le taquet 20 et la dent voisine immédiatement supérieure. Ce jeu va permettre le passage par rotation par le haut de la partie 21 distale du taquet sous l'actionnement du dispositif 30 de commande en allant à l'encontre du ressort 24. Une fois le taquet 20 tourné en ayant sa partie distale orientée vers le haut au-delà de la dent immédiatement voisine supérieure, le chariot mobile est libéré et peut descendre sous la commande du dispositif de commande pneumatique ou hydraulique. Ce processus peut être automatisé par une commande de descente unique alimentée en énergie, sous le contrôle d'un système à logique câblée ou programmée.When it is desired to lower the mobile carriage, the procedure is as follows. The device 30 for raising / lowering the one or more mobile carriages is actuated to cause them to move slightly upwards, creating a small clearance between the cleat 20 and the immediately adjacent upper tooth. This clearance will allow the rotation passage from the top of the distal portion 21 of the latch under the actuation of the control device 30 against the spring 24. Once the stop 20 is turned with its distal portion facing towards the top beyond the immediate next top tooth, the movable carriage is released and can descend under the control of the pneumatic or hydraulic control device. This process can be automated by a single energy-fed descent control under the control of a wired or programmed logic system.

On obtient ainsi un système particulièrement simple de sécurité de blocage/déblocage du ou des chariots mobiles d'un pont élévateur. Un inconvénient, cependant, qui se présente pour ce type d'agencement de commande de blocage/déblocage de sécurité d'un pont élévateur est que la crémaillère liée directement au chariot mobile ou fixée au chariot mobile doit avoir une grande extension en hauteur, notamment une hauteur suffisante pour correspondre à la hauteur de laquelle on souhaite surélever le véhicule. Pour ce faire, on a donc besoin de disposer le pont élévateur dans une pièce dont la hauteur jusqu'au plafond doit au moins être égale à deux fois la hauteur dont on souhaite pouvoir surélever le pont élévateur, ce qui, dans certains cas, peut présenter des inconvénients.This provides a particularly simple system of safety locking / unlocking or mobile carriages of a lift. A disadvantage, however, which arises for this type of safety locking / unlocking control arrangement of a lift is that the rack connected directly to the mobile carriage or attached to the movable carriage must have a large extension in height, in particular a height sufficient to match the height of which it is desired to raise the vehicle. To do this, it is necessary to have the lift in a room whose height to the ceiling must be at least twice the height of which it is desired to raise the lift, which in some cases may have disadvantages.

Le mode de réalisation de l'invention représenté à la Figure 2 permet, d'une manière simple, de disposer d'un pont élévateur d'une hauteur maximale bien inférieure à celui de la Figure 1 et notamment qui peut être utilisé dans des pièces ne nécessitant pas une grande hauteur de plafond. On prévoit de disposer le long des colonnes une série d'au moins deux taquets à distance l'un de l'autre. Le ou les deuxièmes taquets 40 sont identiques aux taquets 20. Le chariot mobile de la Figure 2 est en revanche de plus petite dimension en hauteur que celui de la Figure 1. Lorsque le chariot mobile de la Figure 2 entame sa montée, il est d'abord "pris en charge" par le premier taquet 20. Puis lorsque la dernière dent du chariot mobile quitte sa coopération avec le taquet 20, la première dent du chariot mobile entre en coopération avec le taquet 40 suivant qui prend en charge le chariot mobile pour l'assurer contre une chute intempestive lors de sa montée. On pourrait également, bien évidemment, prévoir plus que deux taquets mobiles montés en série 20.The embodiment of the invention shown in Figure 2 allows, in a simple way, to have a lift of a maximum height well below that of the Figure 1 and in particular that can be used in rooms that do not require a high ceiling height. It is expected to have along the columns a series of at least two tabs at a distance from one another. The second or the second tabs 40 are identical to the tabs 20. The movable carriage of the Figure 2 on the other hand is smaller in height than that of the Figure 1 . When the mobile cart of the Figure 2 begins when it is mounted, it is first "supported" by the first cleat 20. Then when the last tooth of the movable carriage leaves its cooperation with the cleat 20, the first tooth of the movable carriage enters into cooperation with the cleat 40 next which supports the mobile cart to ensure against an accidental fall during its rise. One could also, of course, provide more than two mobile cleats mounted in series 20.

La dimension en hauteur du chariot, c'est-à-dire la dimension en hauteur de la crémaillère, est sensiblement égale à la distance entre le taquet 20 et le taquet 40, en étant légèrement plus grande, par exemple d'une dimension en hauteur d'une dent.The height dimension of the carriage, that is to say the height dimension of the rack, is substantially equal to the distance between the cleat 20 and the catch 40, being slightly larger, for example of a dimension in height. height of a tooth.

La dimension en hauteur du chariot, c'est-à-dire également de la crémaillère, est inférieure à la hauteur (distance du sol dans la direction verticale) du taquet 40 le plus haut des au moins deux taquets. La dimension en hauteur du chariot est inférieure à la hauteur du taquet 20 le plus bas.The height dimension of the carriage, that is to say also of the rack, is less than the height (distance from the ground in the vertical direction) of the stopper 40. higher of at least two cleats. The height dimension of the carriage is less than the height of the lower tab 20.
