Description

L'invention concerne une installation mécanisée à gestion entièrement automatisée pour le stockage de véhicules automobiles.The invention relates to a mechanized installation with fully automated management for the storage of motor vehicles.

Il existe actuellement de nombreuses conceptions de parcs de stationnement automatisés mécanisés dans lesquels les véhicules sont convoyés d'une aire d'entrée vers une cellule de rangement puis amenés à la demande jusqu'à une aire de sortie. De tels parcs de stationnement sont notamment décrits dans les brevets GB-A-1.043.371 et CH-A-505.969.There are currently many designs of mechanized automated parking lots in which vehicles are conveyed from an entry area to a storage cell and then brought on demand to an exit area. Such parking lots are described in particular in patents GB-A-1,043,371 and CH-A-505,969.

Ainsi, CH-505.969 a trait à un garage automatique pour véhicules comportant une pluralité de cellules rectangulaires disposées de part et d'autre d'une allée de circulation comportant deux rails sur lesquels circule un chariot mobile de transport de véhicules. Chaque cellule est munie le long de ses grands côtés de deux séries de barres de support des roues des véhicules, formant un peigne dont les dents sont tournées vers l'intérieur de la cellule, et le chariot mobile est muni de deux séries de barres de transport formant également un peigne dont les dents sont tournées vers l'extérieur du chariot, ledit chariot mobile pouvant pénétrer a l'intérieur de chaque cellule puis s'abaisser, de telle sorte que les barres de transport passent entre les barres de support et déposent les roues du véhicule transporté sur lesdites barres de support.Thus, CH-505.969 relates to an automatic garage for vehicles comprising a plurality of rectangular cells arranged on either side of a circulation aisle comprising two rails on which a mobile vehicle transport trolley circulates. Each cell is provided along its long sides with two series of vehicle wheel support bars, forming a comb whose teeth are turned towards the inside of the cell, and the mobile carriage is provided with two series of bars transport also forming a comb, the teeth of which are turned towards the outside of the carriage, said mobile carriage being able to penetrate inside each cell and then lower, so that the transport bars pass between the support bars and deposit the wheels of the vehicle transported on said support bars.

Malheureusement, dans les installations du type de celle décrite dans le brevet CH-A-505.969, les cellules de rangement sont disposées perpendiculairement au couloir de circulation du chariot, ce qui nécessite une largeur de couloir au moins égale à la longueur des véhicules les plus longs et donc une surface occupée par le couloir au détriment des places de stationnement. En outre, il est nécessaire d'effectuer un transfert du véhicule à partir du chariot jusqu'à l'intérieur de la cellule de rangement lors du déchargement d'un véhicule (ou inversement), ce qui nécessite une manoeuvre supplémentaire et exige un mécanisme adapté à un tel transfert et donc rend coûteuse une telle installation.Unfortunately, in installations of the type described in patent CH-A-505,969, the storage cells are arranged perpendicular to the circulation corridor of the carriage, which requires a corridor width at least equal the length of the longest vehicles and therefore an area occupied by the corridor to the detriment of parking spaces. In addition, it is necessary to transfer the vehicle from the trolley to the interior of the storage cell when unloading a vehicle (or vice versa), which requires an additional maneuver and requires a mechanism. suitable for such a transfer and therefore makes such an installation expensive.

C'est pourquoi le but de l'invention est de fournir une installation mécanisée de stockage de véhicules automobiles dont la disposition des cellules de rangement permette un gain de place et dont le chargement et le déchargement d'un véhicule dans une cellule se fasse sans manoeuvre supplémentaire à celle du déplacement du chariot de transport des véhicules.This is why the object of the invention is to provide a mechanized installation for storing motor vehicles, the arrangement of the storage cells of which saves space and the loading and unloading of a vehicle in a cell takes place without maneuver additional to that of moving the vehicle transport trolley.

La présente invention a donc pour objet une installation mécanisée à gestion entièrement automatisée pour le stockage de véhicules automobiles, comprenant

  • au moins un couloir de circulation comprenant une rainure de guidage dite principale ménagée longitudinalement le long du couloir,
  • des cellules de rangement réparties de part et d'autre du couloir de circulation,
  • au moins un chariot comportant un châssis sur roues doté de moyens d'entraînement autonomes, chacun des chariots étant équipé de moyens de guidage adaptés pour permettre de déplacer le chariot le long du couloir de circulation et de l'amener aux cellules de rangement, et de moyens de chargement et déchargement aptes à permettre de saisir ou de déposer un véhicule automobile dans une cellule déterminée, et
  • une unité centrale de gestion apte à gérer le fonctionnement de chaque chariot et l'actionnement des moyens de chargement et de déchargement;
The present invention therefore relates to a mechanized installation with fully automated management for the storage of motor vehicles, comprising
  • at least one circulation corridor comprising a so-called main guide groove formed longitudinally along the corridor,
  • storage cells distributed on either side of the circulation corridor,
  • at least one carriage comprising a chassis on wheels provided with autonomous drive means, each of the carriages being equipped with guide means adapted to allow the carriage to be moved along the circulation corridor and to bring it to the storage cells, and loading and unloading means capable of making it possible to seize or deposit a motor vehicle in a specific cell, and
  • a central management unit capable of managing the operation of each carriage and the actuation of the loading and unloading means;

L'installation est caractérisée en ce que :

  • les cellules de rangement sont disposées en épi selon un angle d'environ 135° par rapport au couloir de circulation,
  • des rainures de guidage annexes forment des embranchements avec la rainure de guidage principale, et sont agencées pour permettre aux chariots de pénétrer dans les cellules de rangement grâce à des moyens d'aiguillage disposés au droit de chaque embranchement et dont l'activation est commandée par l'unité centrale, et
  • les moyens de guidage de chaque chariot comportent deux galets de guidage adaptés pour coulisser dans la rainure principale et dans les rainures de guidage annexes et pour faire pivoter les roues lorsqu'un des moyens d'aiguillage a été activé pour que le chariot pénètre dans la cellule de rangement en étant guidé par la rainure annexe prolongeant la rainure principale à l'embranchement associé au moyen d'aiguillage.
The installation is characterized in that:
  • the storage cells are arranged on an ear at an angle of about 135 ° relative to the circulation corridor,
  • additional guide grooves form branches with the main guide groove, and are arranged to allow the carriages to enter the storage cells by means of routing arranged at the right of each branch and whose activation is controlled by the central unit, and
  • the guide means of each carriage comprise two guide rollers adapted to slide in the main groove and in the annexed guide grooves and to rotate the wheels when one of the switching means has been activated so that the carriage enters the storage cell being guided by the annex groove extending the main groove to the associated branch by means of switch.

Selon un autre mode de réalisation, le chariot circule sur une piste de circulation formant un circuit fermé doté de 2 couloirs longitudinaux et les cellules sont réparties de part et d'autre de chaque couloir de façon à ce que les deux rangées disposées entre les couloirs soient juxtaposées.According to another embodiment, the carriage circulates on a circulation track forming a closed circuit provided with 2 longitudinal corridors and the cells are distributed on either side of each corridor so that the two rows arranged between the corridors are juxtaposed.

Selon encore un autre mode de réalisation, l'installation comprend en combinaison :

  • au moins deux niveaux superposés comportant chacun :
    • une piste de circulation formant un circuit fermé doté de deux couloirs longitudinaux de circulation,
    • quatre rangées de cellules de rangement réparties de 5 part et d'autre de chaque couloir de circulation, de façon que les deux rangées disposées entre lesdits couloirs soient juxtaposées,
    • au moins un élévateur adapté pour se déplacer entre une aire de chargement et/ou de déchargement et chaque niveau, en vue de desservir lesdits niveaux, chacun des élévateurs étant installé de façon à occuper la place d'une cellule de rangement,
    • pour chaque niveau, au moins un chariot doté de moyens d'entraînement autonomes, et des moyens de guidage de chaque chariot adaptés pour permettre de déplacer ce dernier le long de la piste de circulation, et de l'amener respectivement au droit de chaque élévateur et des cellules de rangement, chacun des chariots étant équipé de moyens de chargement et de déchargement aptes à permettre de saisir et de déposer un objet dans les cellules et dans chaque élévateur,
    • une unité centrale de gestion apte a gérer le fonctionnement de chaque élévateur et de chaque chariot et l'actionnement des moyens de chargement et de déchargement.
According to yet another embodiment, the installation comprises in combination:
  • at least two superimposed levels, each comprising:
    • a circulation track forming a closed circuit provided with two longitudinal circulation corridors,
    • four rows of storage cells distributed on either side of each circulation corridor, so that the two rows disposed between said corridors are juxtaposed,
    • at least one elevator adapted to move between a loading and / or unloading area and each level, in order to serve said levels, each of the elevators being installed so as to occupy the place of a storage cell,
    • for each level, at least one carriage provided with autonomous drive means, and means for guiding each carriage adapted to allow the latter to be moved along of the circulation track, and to bring it respectively to the right of each elevator and storage cells, each of the carriages being equipped with loading and unloading means capable of making it possible to grasp and deposit an object in the cells and in each elevator,
    • a central management unit capable of managing the operation of each lift and each carriage and the actuation of the loading and unloading means.

En premier lieu, le nombre de places de stationnement par rapport à la surface d'une telle installation est élevé car la surface de chaque niveau, utilisée pour le stockage, est égale ou supérieure aux deux tiers de la surface totale des niveaux.First, the number of parking spaces relative to the surface of such an installation is high because the surface of each level, used for storage, is equal to or greater than two thirds of the total surface of the levels.

En outre, les mouvements verticaux des élévateurs et les mouvements horizontaux des chariots sont totalement indépendants, ce qui autorise des cycles de stockage et retrait très courts.In addition, the vertical movements of the elevators and the horizontal movements of the carriages are completely independent, which allows very short storage and withdrawal cycles.

De plus, chaque chariot se déplace par ses propres moyens et la puissance nécessaire est, par conséquent, réduite a son minimum.In addition, each carriage moves on its own and the power required is therefore reduced to a minimum.

Cette disposition permet de prévoir des moyens de chargement et de déchargement de conception simple ne nécessitant, par exemple, aucun système de porte à faux par rapport au chariot qui nuirait à la stabilité de ce dernier. Ainsi, selon un mode de réalisation préférentiel, visant ces moyens de chargement et de déchargement :

  • chaque cellule de rangement et chaque élévateur comprennent deux râteliers fixes, longitudinaux, disposés en vis-à-vis et constitués, chacun, de barres fixes horizontales, parallèles et espacées, lesdits râteliers étant agencés pour délimiter un espace central libre entre les extrémités des barres fixes,
  • chaque chariot comporte un châssis sur roues doté de moyens d'entraînement autonomes,
  • les moyens de chargement et de déchargement comprennent:
    • un support mobile porté par le châssis des chariots et comportant une structure centrale longitudinale, de largeur 20 inférieure à celle de l'espace central ménagé entre deux râteliers fixes, et deux séries de barres horizontales, parallèles et espacées, s'étendant orthogonalement de part et d'autre de la structure centrale,
    • des moyens de déplacement vertical du support mobile, portés par le châssis, et aptes à déplacer ledit support lorsqu'un chariot se trouve dans une cellule de rangement ou un élévateur, entre une position basse où ce support se trouve en-dehors du plan des râteliers fixes, et une position où il se trouve au dessus du plan de ces râteliers fixes.
This arrangement makes it possible to provide means of loading and unloading of simple design requiring, for example, no system of cantilever with respect to the carriage which would harm the stability of the latter. Thus, according to a preferred embodiment, targeting these means of loading and unloading:
  • each storage cell and each elevator comprises two fixed, longitudinal racks, placed opposite one another and each consisting of horizontal, parallel and spaced fixed bars, said racks being arranged to delimit a free central space between the ends of the bars fixed,
  • each carriage comprises a chassis on wheels provided with autonomous drive means,
  • loading and unloading means include:
    • a mobile support carried by the chassis of the carriages and comprising a longitudinal central structure, of width 20 less than that of the central space formed between two fixed racks, and two series of horizontal bars, parallel and spaced, extending orthogonally on either side of the central structure,
    • means for vertical displacement of the mobile support, carried by the chassis, and able to move said support when a carriage is in a storage cell or a lift, between a low position where this support is outside the plane of the fixed racks, and a position where it is above the plane of these fixed racks.

Les opérations de chargement et de déchargement ne nécessitent donc qu'un déplacement vertical sur une faible distance du support mobile pouvant avantageusement être réalisé au moyen de deux vérins agencés verticalement et fixés sur le châssis des chariots.The loading and unloading operations therefore require only a vertical displacement over a short distance of the movable support which can advantageously be achieved by means of two jacks arranged vertically and fixed to the chassis of the carriages.

Par ailleurs, selon une autre caractéristique de l'invention, chaque élévateur comprend un plancher mobile doté de lumières aptes à loger les barres horizontales des râteliers fixes, et des moyens de déplacement vertical du plancher entre une position haute ou il se trouve dans le plan des râteliers, et un position basse où il se trouve escamoté sous les râteliers de façon à se profiler avec la piste de circulation du niveau desservi.Furthermore, according to another characteristic of the invention, each elevator comprises a movable floor provided with lights capable of accommodating the horizontal bars of the fixed racks, and means for vertically moving the floor between a high position or it is in the plane racks, and a low position where it is retracted under the racks so as to be profiled with the circulation track of the level served.

Ainsi, lorsqu'un véhicule est amené dans un élévateur, le plancher est dans sa position haute et les passagers peuvent donc descendre de ce véhicule et poser les pieds sur un sol plan. Ensuite, ce plancher est amené dans sa position basse dans laquelle il sert de surface de roulement permettant au chariot de pénétrer dans l'élévateur en vue de la saisie du véhicule.Thus, when a vehicle is brought into an elevator, the floor is in its high position and passengers can therefore get out of this vehicle and put their feet on level ground. Then, this floor is brought into its low position in which it serves as a rolling surface allowing the trolley to enter the elevator for the purpose of seizing the vehicle.

Selon une autre caractéristique de l'invention :

  • chaque chariot comporte quatre roues directrices reliées deux à deux par deux essieux par l'intermédiaire de pivots, et
  • les moyens de guidage des chariots actionnent les pivots de deux roues portées par un même essieu par l'intermédiaire de barres de timonerie.
According to another characteristic of the invention:
  • each carriage comprises four steered wheels connected two by two by two axles by means of pivots, and
  • the guide means of the carriages actuate the pivots of two wheels carried by the same axle by means of linkage bars.

De plus, les moyens d'aiguillage comprennent préférentiellement, pour chaque embranchement, un vérin agencé horizontalement et disposé dans une réservation ménagée dans la piste de circulation et débouchant dans la rainure principale, ledit vérin comportant une tige portant un sabot doté d'une face frontale de forme adaptée pour guider le chariot vers une rainure annexe, et étant adapté pour présenter deux états : un état rétracté dans lequel le sabot est en retrait par rapport à la rainure principale, et un état déployé dans lequel ledit sabot est disposé dans ladite rainure.In addition, the switching means preferably comprise, for each branch, a jack arranged horizontally and arranged in a reservation formed in the circulation track and opening into the main groove, said jack comprising a rod carrying a shoe provided with a face. shaped front adapted to guide the carriage towards an additional groove, and being adapted to present two states: a retracted state in which the shoe is recessed with respect to the main groove, and a deployed state in which said shoe is disposed in said groove.

L'invention représentée aux figures consiste en un parc de stationnement mécanisé à gestion entièrement automatisée. Ce parc de stationnement comporte plusieurs niveaux superposés comportant chacun une pluralité des cellules de rangement 1, un élévateur 2 destiné à assurer le transfert des véhicules d'une station d'entrée vers ces niveaux, et un élévateur 3 destiné à assurer le transfert des véhicules des niveaux vers une station de sortie. De plus, ce parc de stationnement comporte, pour chaque niveau, au moins un chariot 4 destiné à transférer les véhicules entre les élévateurs 2, 3, et les cellules de rangement 1.The invention shown in the figures consists of a mechanized car park with fully automated management. This parking lot has several superimposed levels, each comprising a plurality of storage cells 1, an elevator 2 intended to ensure the transfer of vehicles from an entry station to these levels, and an elevator 3 intended to ensure the transfer of vehicles. levels to an exit station. In addition, this parking lot comprises, for each level, at least one carriage 4 intended to transfer the vehicles between the elevators 2, 3, and the storage cells 1.

En premier lieu, chaque niveau comporte une piste de circulation 5 formant un circuit fermé composé de deux couloirs longitudinaux 6 reliés vers leurs extrémités par des tronçons de couloirs semi-circulaires 7.Firstly, each level has a circulation track 5 forming a closed circuit composed of two longitudinal corridors 6 connected towards their ends by sections of semicircular corridors 7.

Chaque niveau comprend, en outre, quatre rangées de cellules de rangement 1 disposées en épi de part et d'autre des couloirs longitudinaux 6, de façon que les deux rangées situées entre lesdits couloirs s'étendent dans le prolongement l'une de l'autre, et que les rangées situées de part et d'autre d'un couloir 6 soient disposées selon un agencement en chevrons.Each level further comprises four rows of storage cells 1 arranged on the cob on either side of the longitudinal corridors 6, so that the two rows located between said corridors extend in the extension of one of the other, and that the rows located on either side of a corridor 6 are arranged in a chevron arrangement.

De plus, les cellules 1 disposées de part et d'autre de chaque couloir longitudinal 6 sont décalées les unes par rapport aux autres d'une distance équivalant à une demi-largeur de cellule.In addition, the cells 1 arranged on either side of each longitudinal corridor 6 are offset from each other by a distance equivalent to half a cell width.

Par ailleurs, deux emplacements de cellules de rangement, en l'exemple deux cellules diamétralement opposées, constituent les fosses verticales dans lesquelles se déplacent les élévateurs 2, 3.Furthermore, two storage cell locations, in the example two diametrically opposite cells, constitute the vertical pits in which the risers 2, 3 move.

La piste de circulation 5 est, en outre, dotée axialement d'une rainure de guidage principale 8, de part et d'autre de laquelle sont ménagées, dans l'axe de chaque emplacement 1, des rainures de guidage annexe 9 s'étendant à l'intérieur desdits emplacements.The circulation track 5 is, moreover, axially provided with a main guide groove 8, on either side of which are arranged, in the axis of each location 1, annex guide grooves 9 extending inside said locations.

Tel que représenté à la figure 2, un poste d'aiguillage est prévu au niveau de chaque embranchement entre la rainure de guidage principale 8 et une rainure de guidage annexe 9. Chacun de ces postes d'aiguillage comprend, en premier lieu, un vérin 10 logé dans une réservation 11 ménagée dans la piste de circulation 5 et débouchant dans la rainure principale 8 en regard d'une rainure annexe 9.As shown in Figure 2, a switching station is provided at each branch between the main guide groove 8 and an additional guide groove 9. Each of these switching stations comprises, firstly, a jack 10 housed in a reservation 11 formed in the circulation track 5 and opening into the main groove 8 opposite an annex groove 9.

Ces vérins 10 sont disposés horizontalement de façon à s'étendre orthogonalement par rapport à la rainure de guidage principale 8. Leur corps 10a est fixé sur une paroi transversale 12 disposée dans chaque réservation 11, tandis que leur tige 10b porte un sabot d'aiguillage 13 guidé, lors de l'actionnement desdits vérins, par deux tiges de guidage 14 solidaires desdits sabots et montées coulissantes par rapport aux parois transversales 12.These jacks 10 are arranged horizontally so as to extend orthogonally relative to the main guide groove 8. Their body 10a is fixed to a transverse wall 12 disposed in each reservation 11, while their rod 10b carries a switching shoe 13 guided, upon actuation of said jacks, by two guide rods 14 integral with said shoes and mounted slidingly with respect to the transverse walls 12.

Chacun des sabots 13 présente une face frontale 13a de forme concave, adaptée pour relier la rainure de guidage principale 8 à la rainure annexe 9 correspondante, lorsque ledit sabot se trouve positionné dans ladite rainure principale. Chaque vérin 10 est, quant à lui, adapté pour présenter deux états : un état rétracté dans lequel le sabot 13 est disposé dans la réservation 11, en retrait latéralement par rapport à la rainure principale 8 et un état déployé dans lequel le sabot 13 est disposé dans ladite rainure principale.Each of the shoes 13 has a front face 13a of concave shape, adapted to connect the main guide groove 8 to the corresponding annex groove 9, when said shoe is positioned in said main groove. Each cylinder 10 is, in turn, adapted to present two states: a retracted state in which the shoe 13 is disposed in the reservation 11, laterally recessed relative to the main groove 8 and a deployed state in which the shoe 13 is disposed in said main groove.

Ces rainures de guidage principales 8 et annexes 9 et ces postes d'aiguillage servent à guider un chariot 4 de façon à permettre à ce dernier, d'une part, de se déplacer le long de la piste de circulation 5, et d'autre part, de pénétrer dans les cellules de rangement 1 et les élévateurs 2, 3, en vue du chargement ou du déchargement d'un véhicule.These main guide grooves 8 and annexes 9 and these switching stations are used to guide a carriage 4 so as to allow the latter, on the one hand, to move along the circulation track 5, and on the other part, to enter the storage cells 1 and the risers 2, 3, for the loading or unloading of a vehicle.

Ces chariots 4 dotés de moyens de propulsion 15 autonomes, aptes à engendrer leur déplacement en marche avant ou en marche arrière, tels que batterie électrique, sont préférentiellement au nombre de deux par niveau : un chariot en service et un chariot en charge.These trolleys 4 provided with autonomous propulsion means 15, capable of generating their displacement in forward or reverse gear, such as an electric battery, are preferably two in number per level: a trolley in service and a trolley in charge.

Tel que représenté aux figures 6 à 10, chaque chariot 4, comporte, en premier lieu, un châssis 16 monté sur deux essieux 17 portant chacun deux roues directrices 18 par l'intermédiaire de pivots 19.As shown in Figures 6 to 10, each carriage 4 comprises, firstly, a chassis 16 mounted on two axles 17 each carrying two steered wheels 18 by means of pivots 19.

Chacun de ces chariots 4 comporte, en outre, pour chaque essieu 17, un arbre de direction vertical 20 relié aux pivots 19 par l'intermédiaire de barres de timonerie 21. Cet arbre 20 porte un galet de guidage horizontal 22 en caoutchouc agencé pour se déplacer dans les rainures de guidage 8, 9. Ce galet de guidage 22 est monté sur une jante 23 disposée autour d'un roulement à billes 24 porté par l'arbre de direction 20.Each of these carriages 4 further comprises, for each axle 17, a vertical steering shaft 20 connected to the pivots 19 by means of linkage bars 21. This shaft 20 carries a horizontal guide roller 22 made of rubber arranged to be move in the guide grooves 8, 9. This guide roller 22 is mounted on a rim 23 disposed around a ball bearing 24 carried by the steering shaft 20.

Chaque chariot 4 comporte également un support mobile 25 porté par deux vérins 26 agencés verticalement sur le châssis 16. Ce support mobile 25 se compose d'une structure centrale longitudinale 27 et de deux séries de barres horizontales 28, parallèles et espacées, s'étendant orthogonalement de part et d'autre de la structure centrale 27.Each carriage 4 also comprises a mobile support 25 carried by two jacks 26 arranged vertically on the chassis 16. This mobile support 25 is composed of a longitudinal central structure 27 and two series of horizontal bars 28, parallel and spaced, extending orthogonally on either side of the central structure 27.

Chaque cellule de rangement 1 et chaque élévateur 2, 3 comportent quant à eux, deux râteliers fixes 29, longitudinaux, disposés en vis-à-vis, et constitués chacun de barres fixes horizontales, parallèles et espacées. Ces râteliers 29 sont adaptés, en premier lieu, pour délimiter entre les extrémités des barres, un espace central libre de largeur supérieure à celle de la structure centrale 27 des chariots 4.Each storage cell 1 and each elevator 2, 3 comprise two fixed racks 29, longitudinal, arranged opposite, and each consisting of horizontal fixed bars, parallel and spaced. These racks 29 are adapted, firstly, to delimit between the ends of the bars, a free central space of width greater than that of the central structure 27 of the carriages 4.

Ces râteliers 29 sont, en outre, disposés de façon à définir un plan support horizontal s'étendant sensiblement au-dessous des barres 28 des chariots 4, dans la position haute du support mobile 25 de ces derniers (figure 10), et s'étendant au-dessus de ces barres 28 dans la position basse dudit support mobile (figure 11).These racks 29 are, moreover, arranged so as to define a horizontal support plane extending substantially below the bars 28 of the carriages 4, in the high position of the mobile support 25 of the latter (FIG. 10), and s' extending above these bars 28 in the low position of said movable support (Figure 11).

Chaque élévateur 2, 3 comprend, par ailleurs, un plancher mobile 30 doté de lumières aptes à loger les barres horizontales des râteliers fixes 29 équipant cet élévateur.Each elevator 2, 3 further comprises a movable floor 30 provided with lights capable of accommodating the horizontal bars of the fixed racks 29 equipping this elevator.

Ce plancher mobile 30 est porté par quatre vérins 31 agencés verticalement et adaptés pour le déplacer entre une position haute où il se trouve dans le même plan horizontal que les râteliers 29, et une position basse où il se trouve escamoté sous lesdits râteliers de façon à se profiler avec la piste de circulation 5 du niveau desservi.This movable floor 30 is carried by four jacks 31 arranged vertically and adapted to move it between a high position where it is in the same horizontal plane as the racks 29, and a low position where it is retracted under said racks so as to profile yourself with the runway 5 of the level served.

Ce plancher mobile 30 est, en outre, doté d'une rainure de guidage (non représentée) agencée pour venir dans le prolongement d'une rainure de guidage annexe 9 ménagée à chaque niveau desservi.This movable floor 30 is, moreover, provided with a guide groove (not shown) arranged to come in the extension of an annex guide groove 9 formed at each level. served.

Lorsqu'un élévateur 2, 3 se trouve à la station d'entrée ou à la station de sortie, le plancher mobile 30 est disposé en position haute permettant aux passagers de poser les pieds sur un sol plan lorsqu'ils descendent du véhicule ou viennent récupérer celui-ci.When a lift 2, 3 is at the entry station or at the exit station, the movable floor 30 is placed in the high position allowing passengers to put their feet on level ground when they get out of the vehicle or come get this one.

Par contre, ce plancher mobile 30 est ensuite escamoté, en position basse, et permet aux chariots 4 de pénétrer dans l'élévateur 2, 3 en vue du chargement ou du déchargement d'un véhicule.By cons, this movable floor 30 is then retracted, in the low position, and allows the carriages 4 to enter the elevator 2, 3 for the loading or unloading of a vehicle.

Par ailleurs, afin de faciliter le centrage du véhicule lorsque celui-ci est introduit dans l'élévateur au niveau de la station d'entrée, celle-ci peut être également équipée de galets constitués de rouleaux à axes verticaux ou inclinés adaptés pour guider latéralement ce véhicule .Furthermore, in order to facilitate the centering of the vehicle when it is introduced into the elevator at the entry station, the latter can also be equipped with rollers made up of rollers with vertical or inclined axes adapted to guide laterally. this vehicle.

En dernier lieu, l'installation est doté de moyens de détection tels que cellules émettrices-réceptrices adaptées respectivement pour :

  • stopper les chariots 4 une fois que ceux-ci ont dépassé l'embranchement correspondant à la cellule de rangement sélectionnée par l'unité centrale de gestion,
  • stopper les chariots 4 lorsque ceux-ci ont pénétré dans une cellule de rangement 1 ou un élévateur 2, 3.
Finally, the installation is provided with detection means such as transmitter-receiver cells adapted respectively for:
  • stop the carriages 4 once they have exceeded the branch corresponding to the storage cell selected by the central management unit,
  • stop the carriages 4 when they have entered a storage cell 1 or a lift 2, 3.

Tous les dispositifs et appareils décrits ci-dessus, mis en mouvement pour le fonctionnement automatisé du parc de stationnement, obéissent aux commandes d'une unité centrale de gestion programmée pour faire fonctionner ce parc de stationnement de la façon suivante :

  • lorsqu'un véhicule se présente à la station d'entrée, le plancher mobile 30 se trouve en position haute ce qui permet au conducteur d'introduire son véhicule dans l'élévateur 2 ou 3 et de descendre de ce dernier en posant les pieds sur un sol plan.
  • une fois que le conducteur a quitté cet élévateur 2 ou 3, les portes de ce dernier (non représentées), sont verrouillées. En outre, un distributeur permet au conducteur de retirer un ticket sur lequel sont indiqués le niveau et la cellule de rangement sélectionnés par l'unité centrale de gestion.
  • l'élévateur 2 ou 3 descend alors jusqu'au niveau sélectionné, le plancher mobile 30 étant parallèlement escamoté de façon à amener les véhicules à reposer sur les râteliers fixes 29. Dans un même temps, le chariot 4 du niveau sélectionné est stoppé devant l'emplacement correspondant à l'élévateur grâce à l'activation de la cellule émettrice-réceptrice correspondante.
All the devices and apparatuses described above, set in motion for the automated operation of the parking lot, obey the commands of a central management unit programmed to operate this parking lot as follows:
  • when a vehicle presents itself at the entry station, the movable floor 30 is in the high position which allows the driver to introduce his vehicle into the elevator 2 or 3 and get out of it by putting his feet on level ground.
  • once the driver has left this lift 2 or 3, the latter's doors (not shown) are locked. In addition, a dispenser allows the driver to withdraw a ticket on which are indicated the level and the storage cell selected by the central management unit.
  • the elevator 2 or 3 then descends to the selected level, the movable floor 30 being parallel retracted so as to bring the vehicles to rest on the fixed racks 29. At the same time, the carriage 4 of the selected level is stopped in front of the location corresponding to the elevator thanks to the activation of the corresponding transceiver cell.

Une fois l'élévateur parvenu au niveau, le chariot 4 recule dans ce dernier grâce à l'actionnement du vérin d'aiguillage 10 situé au niveau de l'embranchement menant à cet élévateur.Once the elevator has reached the level, the carriage 4 moves back in the latter thanks to the actuation of the switching cylinder 10 located at the branch leading to this elevator.

Le support mobile 25 est ensuite soulevé de façon que les barres 28 de ce dernier passent au travers des râteliers 29. Le véhicule se trouve alors porté par le chariot 4 qui est déplacé le long de la piste de circulation 5, le support mobile 25 restant en position haute ou étant ramené en position basse, jusqu'à ce qu'il soit stoppé par la cellule émettrice-réceptrice correspondant à l'emplacement sélectionné.The mobile support 25 is then lifted so that the bars 28 of the latter pass through the racks 29. The vehicle is then carried by the carriage 4 which is moved along the circulation track 5, the mobile support 25 remaining in the high position or being brought back to the low position, until it is stopped by the transmitter-receiver cell corresponding to the selected location.

Le vérin d'aiguillage 10 correspondant à cet emplacement est alors actionné et le chariot 4 recule jusqu'à ce qu'il soit stoppé par la cellule émettrice-réceptrice disposée dans le fond de la cellule de rangement 1.The switching jack 10 corresponding to this location is then actuated and the carriage 4 moves back until it is stopped by the transmitter-receiver cell arranged in the bottom of the storage cell 1.

Les vérins 26 sont alors rétractés et le véhicule déposé sur les râteliers 29. Une fois ce dépôt effectué, le chariot 4 est ramené sur la piste de circulation 5, le long de laquelle il se déplace jusqu'à ce qu'il soit stoppé par une cellule émettrice-réceptrice activée. Selon le cas, cet arrêt peut être commandé soit, en regard de l'élévateur 2 ou 3 si un nouveau véhicule est amené, soit, en regard d'un emplacement si un utilisateur désire retirer son véhicule.The jacks 26 are then retracted and the vehicle deposited on the racks 29. Once this deposit has been made, the carriage 4 is brought back to the circulation track 5, along which it moves until it is stopped by an activated transceiver cell. Depending on the case, this stop can be ordered either, facing the elevator 2 or 3 if a new vehicle is brought, or, opposite a location if a user wishes to remove his vehicle.

Dans ce deuxième cas, il suffit à l'utilisateur de se présenter à la station de sortie et d'introduire le ticket qui lui a été délivré dans un lecteur électronique. Le cycle de sortie consiste alors à amener le chariot 4 du niveau considéré en regard de l'emplacement désiré, comme indiqué ci-dessus, et à commander la descente de l'élévateur de sortie 2 ou 3. Les opérations suivantes correspondent ensuite, en sens inverse, à celles effectuées pour la rentrée d'un véhicule.In this second case, the user need only present himself at the exit station and introduce the ticket which has been issued to him in an electronic reader. The output cycle then consists in bringing the carriage 4 of the level considered opposite the desired location, as indicated above, and in controlling the descent of the output elevator 2 or 3. The following operations then correspond, in opposite direction, to those carried out for the retraction of a vehicle.

Les figures 13 et 14 mettent en évidence un autre mode de réalisation d'un chariot selon l'invention.Figures 13 and 14 highlight another embodiment of a carriage according to the invention.

Ledit chariot 40 comporte un châssis 41 dans sa partie basse et un plateau mobile 42 dans sa partie haute. Ledit châssis 41 est pourvu de quatre roues stabilisatrices 51, 52, 53, 54, montées en "roues folles". L'une des deux traverses du châssis reçoit une roue motrice 43 qui assure l'entraînement autonome dudit chariot 40.Said carriage 40 comprises a chassis 41 in its lower part and a movable plate 42 in its upper part. Said chassis 41 is provided with four stabilizing wheels 51, 52, 53, 54, mounted in "crazy wheels". One of the two crossmembers of the chassis receives a drive wheel 43 which ensures the autonomous drive of said carriage 40.

Des vérins 44, 45, 46, 47 assurent le mouvement ascendant ou descendant du plateau mobile 42.Cylinders 44, 45, 46, 47 ensure the upward or downward movement of the movable plate 42.

Le plateau mobile 42 est composé d'une poutre longitudinale 48 de laquelle est issu, de chaque côté, un râtelier 49, 50 dont la largeur et la longueur correspondent aux râteliers 29 des cellules de rangement 1.The movable plate 42 is composed of a longitudinal beam 48 from which comes, on each side, a rack 49, 50 whose width and length correspond to the racks 29 of the storage cells 1.

Un des avantages de ce dernier mode de réalisation de ce chariot 40 réside dans sa roue motrice 43. Ainsi lorsque le chariot 40 recule dans la cellule de rangement 1, la roue motrice 43 qui peut être tractrice et qui est disposée au milieu d'une traverse avant 55 dudit chariot 40, ne pénètre que très peu dans la cellule de rangement. Ce ne sont que les roues stabilisatrices 51, 52, 53, 54, qui sont de chaque côté du chariot 40, qui pénètrent de chaque côté de la cellule de rangement. A cet effet, la cellule de rangement comporte sur ses côtés longitudinaux, un fer en U ou similaire, sur lequel les roues stabilisatrices peuvent rouler. Ainsi, le plancher peut être supprimé à 75 % du parc de stationnement, le coût de fabrication de l'installation est diminué en particulier pour les containers.One of the advantages of this latter embodiment of this carriage 40 resides in its driving wheel 43. Thus when the carriage 40 moves back in the storage cell 1, the driving wheel 43 which can be towing and which is arranged in the middle of a front cross member 55 of said carriage 40, penetrates very little into the storage cell. It is only the stabilizing wheels 51, 52, 53, 54, which are on each side of the carriage 40, which penetrate on each side of the storage cell. For this purpose, the storage cell comprises on its longitudinal sides, a U-shaped iron or the like, on which the stabilizing wheels can roll. Thus, the floor can be removed at 75% of the parking lot, the manufacturing cost of the installation is reduced in particular for containers.

Dans les figures 15, 16, 17 et 18, sont représentés schématiquement les chariots 56 et 57 qui peuvent aussi bien charger un véhicule 58 que le décharger.In FIGS. 15, 16, 17 and 18, the carriages 56 and 57 are shown schematically which can load a vehicle 58 as well as unload it.

Les chariots 56, 57 sont pourvus de vérins qui permettent de manoeuvrer le plateau mobile 49.The carriages 56, 57 are provided with jacks which allow the movable plate 49 to be maneuvered.

L'élévateur 59 est pourvu de deux portes d'accès 60, 61. Il est disposé dans la cage d'ascenseur 62.The elevator 59 is provided with two access doors 60, 61. It is arranged in the elevator shaft 62.

Les figures 19, 20, 21 mettent en évidence le moyen d'aiguillage 63.Figures 19, 20, 21 highlight the switching means 63.

Ledit moyen d'aiguillage 63, qui permet le guidage du chariot 40 dans son rail 64, est composé de trois pièces solidaires. Un axe 65 solidaire du chariot 40 sur lequel il est monté oscillant avec son bras 66 à l'extrémité duquel se trouve une came de guidage 67. Le pivotement du moyen de guidage suivant les flèches F1 ou F2, c'est à dire à droite ou à gauche, s'effectue, par exemple, par un moteur électrique (non représenté) qui permet d'assurer le pivotement.Said switching means 63, which allows the carriage 40 to be guided in its rail 64, is composed of three integral parts. An axis 65 integral with the carriage 40 on which it is mounted oscillating with its arm 66 at the end of which is a guide cam 67. The pivoting of the guide means according to the arrows F1 or F2, that is to say to the right or to the left, is carried out, for example, by an electric motor (not shown) which allows the pivoting to be ensured.
