Abstract

The invention concerns a mobile platform for equipping spaces convertible into plain flooring or bleachers, borne by lifting means, comprising an upper platform (14) forming a floor mounted on a central structure and two mobile side walls (15) including each at its top a rim (15a) recessed perpendicularly to said platform, whereof the inner edge has a profile (15b) diverging downwards opposite the platform (14), the relative vertical displacement of said side walls relative to the central structure causes an induced movement of lateral translation (centrifugal or centripetal) of the side walls relative to the central structure.

Description

EQUIPEMENT POUR L'AMENAGEMENT DES ESPACES INTERIEURS La présente invention concerne le domaine des équipements pour l'aménagement intérieur de locaux publics ou privés et notamment les salles de réunion ou de spectacle du type polyvalent comportant des plates-formes individuelles ajustables en hauteur The present invention relates to the field of equipment for the interior layout of public or private premises and in particular meeting or performance rooms of the multipurpose type comprising individual platforms adjustable in height.
De telles plates-formes à hauteur variables sont décrites dans le brevet français N° 85 13 981 au nom du demandeur. Ces plates-formes, devant subir des modifications individuelles de leur positionnement en hauteur, doivent nécessairement rester séparées avec un interstice mmimal pour permettre leurs déplacements mutuels, alors qu'à l'inverse il est souhaitable d'obtenir un appui mutuel des plates-formes pour la stabilité de l'ensemble, et l' étanchéité du plancher.Such variable height platforms are described in French patent No. 85 13 981 in the name of the applicant. These platforms, having to undergo individual modifications of their height positioning, must necessarily remain separated with a minimum gap to allow their mutual displacements, while conversely it is desirable to obtain mutual support of the platforms for the stability of the whole, and the waterproofness of the floor.
Une solution a été avancée par le brevet français 87 05 837 proposant des jupes latérales sur les longs cotés des plates-formes, jupes formées de parois susceptibles par un mouvement à la fois ascensionnel et d'écartement centrifuge, de venir à la rencontre de la paroi voisine. La présente invention développe et perfectionne la réponse apportée par le brevet antérieur précité par une amélioration de la manœuvre des jupes d'étanchéité et d'autoblocage. L'invention prévoit encore un système de translation de plateaux secondaires depuis une position de stockage à l'intérieur d'une première plate-forme ou plate-forme émettrice en position haute vers une position active au sommet d'une seconde plate-forme réceptrice disposée dans le prolongement de la première.A solution has been put forward by French patent 87 05 837 proposing side skirts on the long sides of the platforms, skirts formed from walls capable of coming both upward and through centrifugal spacing, to meet the neighboring wall. The present invention develops and improves the response provided by the aforementioned prior patent by improving the operation of the sealing and self-locking skirts. The invention also provides a system for translating secondary plates from a storage position inside a first platform or transmitting platform in the high position to an active position at the top of a second receiving platform. arranged in the extension of the first.
Chaque plate-forme pourra ainsi contenir un plateau auxiliaire éventuellement muni d'équipements annexes, tels que sièges ; une fois amenée en position haute cette plate-forme peut alors évacuer son plateau auxiliaire vers le plateau supérieur de la plate-forme voisine positionnée à hauteur appropriée dans son prolongement axial ; la répétition de ce mouvement de chaque plate-forme à sa voisine permet de mettre en position supérieure active les plateaux auxiliaires, par exemples garnis de siège.Each platform will thus be able to contain an auxiliary tray possibly fitted with ancillary equipment, such as seats; once brought into the high position, this platform can then evacuate its auxiliary plate towards the upper plate of the neighboring platform positioned at an appropriate height in its axial extension; the repetition of this movement from each platform to its neighbor makes it possible to place the auxiliary plates, for example fitted with seats, in the upper position.
A cet effet l'invention concerne une structure de plate-forme mobile pour l'équipement de salles polyvalentes et conforme aux caractéristiques décrites dans la revendication 1.To this end, the invention relates to a mobile platform structure for equipping multipurpose rooms and conforming to the characteristics described in claim 1.
Les caractéristiques et avantages de l'invention ressortiront encore de la description qui suit présentée à titre d'exemple et en se référant aux dessins annexés. La figure 1 représente une vue schématique en perspective de l'extrémité transversale d'une plate-forme selon les quatre phases de son élévation représentées en coupe aux figures 2 à 5 et 6 à 9.The characteristics and advantages of the invention will become more apparent from the description which follows, presented by way of example and with reference to the attached drawings. FIG. 1 represents a schematic perspective view of the transverse end of a platform according to the four phases of its elevation represented in section in FIGS. 2 to 5 and 6 to 9.
Les figures 6A et 7A représente des vues en coupe partielle d'une extrémité de plate-forme telle que représentée aux figures 6 et 7 respectivementFIGS. 6A and 7A represent views in partial section of one end of the platform as shown in FIGS. 6 and 7 respectively
La figure 10 représente une vue en perspective avec arraché partiel de la structure d'une plate-forme avec ses parois latérales.Figure 10 shows a perspective view with partial cutaway of the structure of a platform with its side walls.
La figure 11 représente une vue schématique du mécanisme d'entraînement mutuel vertical de la paroi latérale et de la structure centrale La figure 12 représente une vue en élévation latérale du même mécanisme intégrant la manoeuvre des arbres actionnant les galets de déplacement des plateaux auxiliaires, les figures 14, 16 et 18 sont identiques mais présentent le même mécanisme dans des positions actives ou inactives différentesFIG. 11 represents a schematic view of the mutual vertical drive mechanism of the side wall and of the central structure FIG. 12 represents a side elevation view of the same mechanism integrating the operation of the shafts actuating the rollers for moving the auxiliary plates, the Figures 14, 16 and 18 are identical but have the same mechanism in different active or inactive positions
La figure 13 donne une vue en coupe transversale de la plate-forme montrant le même mécanisme de déplacement du plateau auxiliaire dans sa position de la figure 12, ce mécanisme est également vu sur les figures 15, 17 et 19, dans les positions différentes, chacune correspondant à la vue en élévation présentée sur la même planche.FIG. 13 gives a cross-sectional view of the platform showing the same mechanism for moving the auxiliary plate in its position in FIG. 12, this mechanism is also seen in FIGS. 15, 17 and 19, in the different positions, each corresponding to the elevation view presented on the same board.
Les figures 20 et 21 montrent deux phases successives d'échange de leurs plateaux auxiliaires entre deux plates-formes voisines.Figures 20 and 21 show two successive phases of exchange of their auxiliary plates between two neighboring platforms.
La figure 22 représente une vue de deux plates-formes voisines et coaxiales reposant sur un caisson relevable commun.FIG. 22 represents a view of two neighboring and coaxial platforms resting on a common lifting box.
La figure 23 représente en coupe trois plates-formes voisines contenant un plateau auxiliaire intérieur porteur de sièges, et ayant reçu d'une plate-forme coaxialement voisine un plateau auxiliaire en place au sommet de la plate-forme, les figures 24 et 25 représentent en coupe deux plates-formes individuelles dans la même situation.FIG. 23 represents in section three neighboring platforms containing an interior auxiliary tray carrying seats, and having received from an coaxially adjacent platform an auxiliary plate in place at the top of the platform, FIGS. 24 and 25 represent in section two individual platforms in the same situation.
On se réfère en premier à la figure 22 qui représente la forme de réalisation de l'invention la plus courante, étant adaptée à l'implantation et l'équipement de salles polyvalentes comportant des rangées de sièges ou gradins en nombre important ; les caissons supports 1 et leur mécanisme de levage (représenté schématiquement par les vérins 2, 2 ') permettent des déplacements en hauteur importants nécessaires pour la conformation des étages de gradins. Ces caissons étant de type connu pour la constitution de salles polyvalentes ne seront pas décrits plus avant et ils ne sont pas représentés aux dessins des figures 1 à 22. Dans ces derniers pour la simplification et la clarté des figures on a représenté les plates-formes de l'invention, le plus souvent sans appui de référence, cet appui pouvant être le sol (plates- formes intégrées dans une fosse, ou le pan supérieur d'un caisson 1).First, reference is made to FIG. 22 which represents the most common embodiment of the invention, being suitable for setting up and equipping multipurpose rooms comprising rows of seats or bleachers in large numbers; the support boxes 1 and their lifting mechanism (shown schematically by the cylinders 2, 2 ') allow significant height displacements necessary for the conformation of the tiers of steps. These boxes being of a type known for the constitution of multipurpose rooms will not be described further and they are not shown in the drawings of Figures 1 to 22. In the latter for the simplification and clarity of the figures the platforms are shown of the invention, most often without a reference support, this support possibly being the ground (platforms integrated into a pit, or the upper section of a box 1).
Chaque plate-forme de l'invention telle que représentée aux figures 1 à 35 sous la référence générale 10 et ses dérivés (10a, 10b etc.... ) comporte son mécanisme de levage propre à la plate-forme et schématisé sous la référence 3 sur la figure 22 ; ces moyens de levage, de type connu (voir le brevet français 85 13 981 précité) supportent une structure centrale ci-après décrite. Ces moyens de levage 3 de chaque plate-forme ne seront pas repris dans les dessins.Each platform of the invention as shown in FIGS. 1 to 35 under the general reference 10 and its derivatives (10a, 10b, etc.) comprises its own lifting mechanism for the platform and shown diagrammatically under the reference 3 in Figure 22; these lifting means, of known type (see French patent 85 13 981 cited above) support a central structure described below. These lifting means 3 of each platform will not be included in the drawings.
Les figures 1 et les figures suivantes montrent la dynamique fonctionnelle des plates-formes susceptibles de prendre les configurations successives synthétisées sur la figure 1 à savoir : figures 2 et 6 plate-forme bloquée position basse Figures 3 et 7 plate-forme dégagée et plateau ouvert position basse Figures 4 et 8 plate-forme dégagée plateau ouvert position ascendante Figures 6 et 9 plate-forme bloquée plateau refermé position haute.Figures 1 and the following figures show the functional dynamics of the platforms likely to take the successive configurations synthesized in Figure 1 namely: Figures 2 and 6 platform locked low position Figures 3 and 7 platform clear and open platform low position Figures 4 and 8 open platform open platform up position Figures 6 and 9 locked platform closed platform high position.
Chaque plate-forme comporte une structure centrale constituée d'une pluralité de traverses 11 (figure 10) portant à chaque extrémité un montant latéral 12, solidaire par sa base d'une extrémité de la traverse correspondante 11 ; les traverses 11 sont reliées par des longerons 13 par exemple au nombre de deux, reposant au sommet des traverses. Les traverses sont par exemple au nombre de deux pour une plate-forme rectangulaire et supportent donc quatre montants, à proximité des angles de la plate-forme. L'ensemble traverses et montants reposent sur un mécanisme élévatoire schématisé en 3 sur la figure 22 et en 3 et 4 sur la figure 23, permettant l'élévation de l'ensemble de la plate-forme comme exposé ci-après par rapport à son plan de repos (caisson 1 selon la figure 22 ou fond de fosse selon la figure 23 notamment)Each platform comprises a central structure made up of a plurality of crosspieces 11 (FIG. 10) carrying at each end a lateral upright 12, fixed by its base to one end of the corresponding crosspiece 11; the crosspieces 11 are connected by side rails 13, for example two in number, resting at the top of the crosspieces. The sleepers are for example two in number for a rectangular platform and therefore support four uprights, near the angles of the platform. The set of crosspieces and uprights rests on an elevating mechanism shown diagrammatically at 3 in FIG. 22 and at 3 and 4 in FIG. 23, allowing the elevation of the whole of the platform as set out below with respect to its rest plane (box 1 according to Figure 22 or pit bottom according to Figure 23 in particular)
Au sommet des montants 12 est fixé un plateau plan 14, qui conforme la surface de repos, nntnmmfmt 1<- nlanr.hp.r ςimérie.ur de la nlate-forme en nosition active : ce ϋlateau est donc mobile et deplaçable verticalement avec l'ensemble de la structure centrale formée des traverses 31, montants 12 et longerons 33. Cette structure centrale est reliée aux parois latérales 15, par des moyens mécaniques permettant leur mouvement mutuel. Chaque paroi latérale 15 se termine à son sommet par un rebord 15a sensiblement à angle droit et conformant avec la paroi un L inversé dont le pied horizontal est orienté vers le centre de la plate-forme et donc en direction du plateau central supérieur 14At the top of the uprights 12 is fixed a flat plate 14, which conforms the rest surface, nn t nmmfmt 1 <- nlanr.hp.r ς imérie.ur de la nlate-platform in active nosition: this eaulateau is therefore movable and vertically displaceable with the whole of the central structure formed of the cross members 31, uprights 12 and side members 33. This central structure is connected to the side walls 15, by mechanical means allowing their mutual movement. Each side wall 15 ends at its top with a rim 15a substantially at right angles and conforming with the wall an inverted L whose horizontal foot is oriented towards the center of the platform and therefore towards the upper central plate 14
Ce rebord horizontal est prévu pour venir affleurer au niveau de la surface supérieure du plateau, dans la position active de la plate forme en conformant avec le plateau et de chaque coté de ce dernier un surfaçage ou plancher continu (figures 1 et 6a)This horizontal edge is provided to come flush with the upper surface of the plate, in the active position of the platform, conforming with the plate and on each side of the latter a continuous surfacing or floor (FIGS. 1 and 6a).
Chaque paroi latérale verticale 15 peut être ajourée dans sa partie verticale inférieure aux fins d'allégement ; cette paroi (ajourée ou non) se prolonge sensiblement jusqu'à proximité de la base des montants 12 . Chaque paroi latérale 15 est portée par au moins deux piliers verticaux 26 parallèles aux montants 12, soit au moins un pilier à proximité des extrémités terminales de la plate-forme parallèlépipédique ; un pilier et son montant correspondant étant jumelés pour permettre leur mouvement relatif parallèle, étant tous deux associés à un mécanisme entraînant leur déplacement mutuel télescopique ; ce mécanisme est solidaire de la structure centrale (plateau 14 - montant 12 - traverse 11), il porte sur le pilier et il permet ainsi un déplacement ascendant descendant de la paroi 15, portée par le pilier 26 par rapport à la dite structure centrale ; grâce à des organes de guidage ci-après décrits, ce mécanisme conjugue ce mouvement vertical ascendant de l'ensemble pilier/paroi par rapport à la structure centrale avec un mouvement horizontal de rétraction centripète des parois 15 vers le centre, le mouvement descendant de l'ensemble pilier/paroi (ou mouvement ascendant de la structure centrale par rapport aux parois latérales) provoquant à l'inverse une expansion horizontale centrifuge des parois vers l 'extérieur.Each vertical side wall 15 can be perforated in its lower vertical part for the purposes of lightening; this wall (openwork or not) extends substantially up to near the base of the uprights 12. Each side wall 15 is carried by at least two vertical pillars 26 parallel to the uprights 12, that is to say at least one pillar near the terminal ends of the parallelepiped platform; a pillar and its corresponding amount being paired to allow their relative parallel movement, both being associated with a mechanism causing their mutual telescopic movement; this mechanism is integral with the central structure (plate 14 - upright 12 - cross member 11), it bears on the pillar and it thus allows an upwardly descending movement of the wall 15, carried by the pillar 26 relative to said central structure; thanks to the guide members described below, this mechanism combines this vertical upward movement of the pillar / wall assembly relative to the central structure with a horizontal movement of centripetal retraction of the walls 15 towards the center, the downward movement of the pillar / wall assembly (or upward movement of the central structure with respect to the side walls), conversely causing a centrifugal horizontal expansion of the walls towards the outside.
Ainsi la manœuvre de dégagement du plateau supérieur 14 s'effaçant vers le bas (figure 3 et 7,) correspondant à une élévation de la paroi relativement à la structure centrale, provoque en même temps la rétraction centripète des parois latérales en décollant l'ensemble de la plateforme par rapport à ses parois d'appui (plate-forme voisine ou murs de la fosse) ce qui permet la manœuvre ultérieure de déplacement en hauteur de la plate-forme libérée des forces de friction latérales, selon les figures 4 et 8,. En retour, la remontée du plateau avec la structure centrale vers sa position supérieure active, entraîne l'expansion centrifuge des parois latérales (figure 4) venant alors s'appliquer et chercher appui sur les parois voisines avec autoblocage de l'ensemble.Thus the maneuver to release the upper plate 14 fading downwards (FIGS. 3 and 7), corresponding to an elevation of the wall relative to the central structure, at the same time causes the centripetal retraction of the side walls by peeling off the assembly. of the platform relative to its bearing walls (neighboring platform or walls of the pit) which allows the subsequent maneuver of displacement in height of the platform freed from lateral friction forces, according to Figures 4 and 8 ,. In return, the ascent of the plate with the central structure towards its active upper position, causes centrifugal expansion of the side walls (Figure 4) then being applied and seeking support on the neighboring walls with self-locking of the assembly.
Un mécanisme de manœuvre ici proposé est représenté de façon schématique à la figure 11 ; chaque plate-forme comportant deux parois latérales 15 symétriques est prévue avec deux mécanismes de manœuvre symétriques, chacun longeant une paroi. Chaque mécanisme est constitué d'un tirant 50 formé d'un fer plat disposé sur chant et courant longitudinalement ; ce tirant est manœuvré dans son déplacement longitudinal par un vérin central double effet prenant appui d'un coté sur une traverse 11 (appartenant à la structure centrale ) et déplaçant par son autre coté une entretoise réunissant les deux tirants latéraux ; un seul vérin peut donc assurer la manœuvre synchronisée des deux tirants.An operating mechanism proposed here is shown schematically in Figure 11; each platform comprising two symmetrical side walls 15 is provided with two symmetrical operating mechanisms, each along a wall. Each mechanism consists of a tie rod 50 formed of a flat iron placed on edge and running longitudinally; this tie rod is maneuvered in its longitudinal displacement by a double-acting central jack bearing on one side on a cross member 11 (belonging to the central structure) and moving on its other side a spacer joining the two lateral tie rods; a single cylinder can therefore ensure the synchronized operation of the two tie rods.
Chaque tirant manœuvre un ensemble de transmission apte à transformer le déplacement longitudinal horizontal du tirant en déplacement vertical d'un organe venant en appui sur l'ensemble paroi latérale et son pilier 26, de sorte que la manœuvre longitudinale des tirants (solidaire de la structure fixe ) provoque en portant, après renvoi de 90°, sur l'ensemble pilier/paroi, alternativement la montée et la descente de la paroi par rapport à la dite structure centrale avec un déplacement induit centrifuge/centripète de la paroi.Each tie-rod maneuvers a transmission assembly capable of transforming the horizontal longitudinal displacement of the tie-rod into vertical displacement of a member bearing on the lateral wall assembly and its pillar 26, so that the longitudinal maneuver of the tie-rods (integral with the structure fixed) causes by carrying, after 90 ° return, on the pillar / wall assembly, alternately the ascent and descent of the wall relative to said central structure with a centrifugal / centripetal induced displacement of the wall.
Plus particulièrement, chaque tirant présente sur son corps des lumières traversantes de préférence inclinées à 45 ° par rapport à l'axe longitudinal du tirant, chaque lumière forme une coulisse 54 dont les bords guident le parcours d'un curseur 55, ce dernier étant lui-même prisonnier d'un ensemble ne lui autorisant qu'un déplacement vertical.More particularly, each tie has on its body through lights preferably inclined at 45 ° relative to the longitudinal axis of the tie, each light forms a slide 54 whose edges guide the path of a cursor 55, the latter being itself - even prisoner of a set allowing him only a vertical displacement.
Par exemple le curseur est solidaire d'un coulisseau 56, pris par ses bords entre des moyens de guidage venus de la structure centrale tels les quatre poulies supérieures 57a et 57b et inférieures 58a et 58b. à double gorge, une gorge étant en prise sur le bord du coulisseau 56, la gorge voisine sur la tranche horizontale du tirant 50. En variante (non représentée) le tirant pourrait comporter une crémaillère longitudinale engrenant sur un pignon de renvoi (analogue aux poulies 57,58) en prise sur une crémaillère verticale venue du coulisseau. On comprend que la manœuvre longitudinale du tirant entraîne, par effet de came de la glissière 54 poussant le curseur 55, le déplacement vertical (ascendant ou descendant) du curseur. L'ensemble curseur/coulisseau mobile verticalement est rendu solidaire cinétiquement du pilier 26 ; par exemple par un ergot prolongeant le curseur 55 et engagé dans un logement récepteur sur le pilier 26.For example, the cursor is integral with a slide 56, taken by its edges between guide means coming from the central structure such as the four upper pulleys 57a and 57b and lower 58a and 58b. with a double groove, a groove being engaged on the edge of the slide 56, the adjacent groove on the horizontal edge of the tie rod 50. As a variant (not shown) the tie rod could comprise a longitudinal rack meshing on a return pinion (analogous to pulleys 57.58) engaged on a vertical rack coming from the slide. It is understood that the longitudinal maneuver of the tie rod causes, by the cam effect of the slide 54 pushing the cursor 55, the vertical movement (up or down) of the cursor. The vertically movable cursor / slide assembly is kinetically secured to the pillar 26; for example by a lug extending the slider 55 and engaged in a receiving housing on the pillar 26.
Dans le cours de son mouvement positif provoquant l'élévation du curseur, de l'ergot et de l'ensemble paroi/pilier, le tirant travaille en traction, évitant tout flambage, tandis que dans la manoeuvre inverse le poids de la structure centrale en descente fournit la force motrice entraînant longitudinalement le tirant, freiné par le vérin, de sorte que là encore le tirant travaille en traction. Le mouvement induit d'écartement/rapprochement de la paroi latérale 15 par rapport à la structure centrale sont commandés par les lumières 30, prévues sur chacune des branches des piliers 26, formé d'un tube en U ; ces lumières ont un parcours vertical 30a, prolongé à leur base par un parcours incliné 30b, divergent vers le bas en s' écartant du centre de la plate-forme (figure 8B)In the course of its positive movement causing the elevation of the cursor, the lug and the wall / pillar assembly, the tie rod works in traction, avoiding any buckling, while in the maneuver reverses the weight of the central structure in descent provides the driving force driving the tie rod longitudinally, braked by the jack, so that here again the tie rod works in traction. The induced movement of spacing / approximation of the side wall 15 relative to the central structure are controlled by the slots 30, provided on each of the branches of the pillars 26, formed of a U-shaped tube; these lights have a vertical path 30a, extended at their base by an inclined path 30b, diverge downward away from the center of the platform (FIG. 8B)
Dans les deux lumières jumelles et parallèles entre elles 30 disposées sur les deux branches d'un même pilier 26 est engagé un axe 31 reliant deux ailes venues du montant 12, appartenant à la structure centrale de la plate-forme.In the two twin and parallel openings 30 arranged on the two branches of the same pillar 26 is engaged an axis 31 connecting two wings from the upright 12, belonging to the central structure of the platform.
Ainsi lorsqu'un montant 12 est entraînés en élévation ou descente téïescopique par rapport au pilier 26, les bords de chaque lumière 30 d'un pilier dans lesquelles coulisse l'axe 31 jouent le rôle de came par rapport à cet axe 31 Le déplacement de l'axe 31 (avec le montant 12 et toute la structure centrale ) reste vertical le long de la partie verticale supérieure 30a de la lumière (figure 6A). Lorsque le déplacement descendant du montant et de la structure centrale amène l'axe 31 dans la partie inférieure inclinée 30b de la lumière 30, les piliers et donc la paroi 15 sont attirés progressivement vers l'intérieur (figure 7, 7A), en même temps se poursuit l'abaissement de la structure centrale par rapport à ces parois, correspondant à la manoeuvre de dégagement à la fois du plateau (effacé en position basse) et des parois (décollées de leur appui extérieur) ; et inversement dans le mouvement ascendant de la structure centrale et de l'axe 31 le long de la lumière 30, ce dernier par effet de came, dans sa manœuvre d'ascension le long de la partie inclinée 30b de la lumière 30 repousse progressivement vers l'extérieur le pilier 26 et la paroi correspondante 15 (figure 6, 6A) Selon un développement de l'invention les longerons longitudinaux 13 reliant les traverses 11 et parcourant parallèlement la longueur des plates-formes constituent rails de roulement pour les rouleaux supports 40 (figure 6) porteurs d'un plateau auxiliaire 41 apte à être contenu et stocké à l'intérieur de sa plate-forme en position d'attente et à être mis en position supérieure active sur la plate-forme jumelle, deux plates-formes voisines et coaxiales échangeant leur plateau auxiliaire pour amener ces derniers en position supérieure active, selon le mouvement qui sera ci-après décrit.Thus when a post 12 is driven in telescopic elevation or descent relative to the pillar 26, the edges of each lumen 30 of a pillar in which the axis 31 slides act as a cam relative to this axis 31 The displacement of the axis 31 (with the upright 12 and the entire central structure) remains vertical along the upper vertical part 30a of the light (FIG. 6A). When the downward movement of the upright and of the central structure brings the axis 31 into the inclined lower part 30b of the lumen 30, the pillars and therefore the wall 15 are gradually drawn inwards (FIG. 7, 7A), at the same time time continues the lowering of the central structure with respect to these walls, corresponding to the disengagement maneuver of both the plate (cleared in the low position) and the walls (detached from their external support); and conversely in the upward movement of the central structure and the axis 31 along the lumen 30, the latter by cam effect, in its ascending maneuver along the inclined part 30b of the lumen 30 gradually pushes towards outside the pillar 26 and the corresponding wall 15 (FIG. 6, 6A) According to a development of the invention, the longitudinal beams 13 connecting the crosspieces 11 and running parallel to the length of the platforms constitute running rails for the support rollers 40 (FIG. 6) carrying an auxiliary plate 41 capable of being contained and stored. inside its platform in the waiting position and to be placed in the active upper position on the twin platform, two adjacent and coaxial platforms exchanging their auxiliary plate to bring the latter into the active upper position, according to the movement which will be described below.
Le plateau auxiliaire inférieur 41 reposant sur ses rouleaux porteurs 40 courant sur les longerons 13, est par ailleurs maintenu et entraîné de chaque coté par des trains de galets poussoirs latéraux 42 inférieurs. Par exemple le plateau auxili ire est associé à au moins deux galets latéraux 42, disposés chacun de chaque coté du plateau dans sa position basse de stockage (figure 11 et 12).The lower auxiliary plate 41 resting on its support rollers 40 running on the side members 13, is moreover maintained and driven on each side by trains of lateral push roller 42. For example, the auxiliary tray is associated with at least two lateral rollers 42, each arranged on each side of the tray in its low storage position (FIGS. 11 and 12).
Chaque plate-forme comporte encore des galets poussoirs supérieurs 43, également au nombre d'au moins deux, soit un galet poussoir latéral sur chaque coté de la plate-forme ; ces galets poussoirs supérieurs 43, sont repartis sensiblement sous les rebords 15a et les galets poussoirs inférieurs sont repartis le long des bords du plateau 41 inférieur dans sa position de stockage ; ces galets sont mus depuis un motoréducteur inférieur 44 par l'intermédiaire d'un arbre transversal , desservant de chaque coté de la plate-forme un arbre vertical 46, par des pignons de renvoi d'angle ;Each platform further comprises upper push rollers 43, also at least two in number, ie a lateral push roller on each side of the platform; these upper push rollers 43 are distributed substantially under the flanges 15a and the lower push rollers are distributed along the edges of the lower plate 41 in its storage position; these rollers are moved from a lower geared motor 44 by means of a transverse shaft, serving on each side of the platform a vertical shaft 46, by angle return gears;
Deux plates-formes devant échanger au moins un plateau auxiliaire 41 sont décalées en hauteur, de sorte que les galets poussoirs inférieurs 42 d'une plate-forme (en position haute) soient situés dans le même plan que les galets poussoirs supérieurs 43 de la plate-forme voisine, dont le plateau supérieur 14 a été alors amené en position effacée par abaissement de la structure centrale, (figureslό, 20 et 21) ce plateau supérieur 14, dans sa position effacée constitue alors le plan de roulement sur lequel courent les rouleaux 40 support du plateau arrivant 41. La remontée ultérieure de la structure centrale de la plate-forme réceptrice du plateau 41 (plate-forme de droite sur la figure 18) ramène alors le plan supérieur du plateau 41 au niveau des bords latéraux venus des parois latérales de cette plate-forme pour conformer un plan uniforme. Le blocage du plateau arrivant 41 entre les b;ords 15a de chaque coté assure le verrouillage de la structure et la rigidification de l'ensemble de la plate-forme. Comme représenté à la figure 8B l'ensemble d'entraînement des plateaux. (Galets poussoirs, 42, 43... arbre moteur vertical 46, pignons de renvoi, arbre transversal 45, et motoreducteur 44) sont déplaçables en hauteur selon une course limitée permettant de mettre alternativement en position inactive (dégagée) ou en position active d'appui sur les bords d'un plateau à déplacer, soit les galets poussoirs inférieurs 42, soit les galets poussoirs supérieurs 43. Dans le cas du transfert des figures 20 , les galets poussoirs inférieurs de la plate-forme de droite sont en position active, de même que les galets poussoirs supérieurs de la plate-forme de gauche (situés selon un même plan.) et inversement dans la figure 21.Two platforms to exchange at least one auxiliary plate 41 are offset in height, so that the lower push rollers 42 of a platform (in the high position) are located in the same plane as the upper push rollers 43 of the neighboring platform, the upper plate 14 of which was then brought into the erased position by lowering the central structure, (figureslό, 20 and 21) this upper plate 14, in its erased position then constitutes the rolling plane on which the rollers 40 supporting the arriving tray 41. The subsequent ascent of the central structure of the receiving platform of the tray 41 (right platform in FIG. 18) then brings the upper plane of the tray 41 back to the side edges coming from the side walls of this platform to conform to a uniform plane. The blocking of the arriving plate 41 between the b ; ords 15a on each side ensures the locking of the structure and the stiffening of the whole platform. As shown in FIG. 8B, the plate drive assembly. (Push rollers, 42, 43 ... vertical motor shaft 46, idler gears, transverse shaft 45, and geared motor 44) are movable in height according to a limited stroke making it possible to alternately put in the inactive (disengaged) position or in the active position d 'support on the edges of a tray to be moved, either the lower push rollers 42 or the upper push rollers 43. In the case of the transfer of Figures 20, the lower push rollers of the right platform are in the active position , as well as the upper push rollers of the left platform (located on the same plane.) and vice versa in figure 21.
La manœuvre élévatoire de cet ensemble d'entraînement des galets poussoirs est commandée (figures 14, 16, 18) par les mêmes tirants 50, précédemment décrits et assurant la transmission du mouvement vertical relatif entre structure centrale et paroi.The elevating operation of this drive assembly for the push rollers is controlled (FIGS. 14, 16, 18) by the same tie rods 50, previously described and ensuring the transmission of the relative vertical movement between the central structure and the wall.
Le tirant comporte des secondes glissières 60 recevant un doigt 61 venu de d'un boîtier transversal 62 renfermant l'ensemble d'entraînement des galets 42, 43, ce boîtier étant mobile uniquement selon un axe vertical, de sorte que dans la traction longitudinale du tirant la glissière 60 par effet de came repousse vers le haut le dit doigt et élève le boîtier porteur de l'ensemble d'entraînement, provoquant ainsi un positionnement actif voulu d'un des jeux de galet, précédemment en position inactive, en désactivant l'autre jeuThe tie rod comprises second slides 60 receiving a finger 61 coming from a transverse housing 62 enclosing the drive assembly of the rollers 42, 43, this housing being movable only along a vertical axis, so that in the longitudinal traction of the pulling the slide 60 by cam effect pushes the said finger upwards and raises the bearing housing of the drive assembly, thus causing a desired active positioning of one of the roller sets, previously in the inactive position, by deactivating the other game
On voit de ce qui précède que l'expansion centrifuge des parois 15 permet d'obtenir une continuité parfaite de la surface du plancher de la salle utilisée en plancher horizontal nu de même qu'une autoblocage des plates-formes en appui mutuel (qu'elles soient au même niveau ou étagées) tandis la rétraction centripète des parois permet leur désaccouplent et leur manœuvre indépendante. Les plates-formes de l'invention permettent également de stocker en leur sein tout accessoire d'usage intermittent notamment un plateau auxiliaire 41, ou 41a, susceptible d'être transité depuis une première plate-forme pour être amené en position active sur une seconde plate forme voisine ; cette dernière à son tour peut livrer son plateau auxiliaire pour être mis en place sur le sommet de la première. , Les phases successives étant représentées aux figures 20 et suivantes. Dans la position des plates-formes selon les figures 22, les plates-formes sont en appui par leurs parois latérales 15 au contact des parois extérieures et voisines ; cette position de blocage mutuel est complétée par la remontée des structures centrales des plates-formes transversales 10a avec expansion simultanée des parois latérales de ces plates-formes.It can be seen from the above that the centrifugal expansion of the walls 15 makes it possible to obtain perfect continuity of the surface of the floor of the room used in bare horizontal floor as well as self-locking of the platforms in mutual support (that they are at the same level or stepped) while the centripetal retraction of the walls allows their uncoupling and their independent operation. The platforms of the invention also make it possible to store within them any accessory of intermittent use in particular an auxiliary plate 41, or 41a, capable of being transited from a first platform to be brought into the active position on a second neighboring platform; the latter in turn can deliver its auxiliary tray to be placed on top of the former. , The successive phases being shown in Figures 20 and following. In the position of the platforms according to Figures 22, the platforms are supported by their side walls 15 in contact with the outer and neighboring walls; this position of mutual blocking is completed by the raising of the central structures of the transverse platforms 10a with simultaneous expansion of the side walls of these platforms.
Les plateaux auxiliaires peuvent être porteurs d'équipement d'usage interinittent, donc stockés en position d'attente dans les plates-formes, et susceptible d'être amenés avec leur plateau porteur en position active sur la plate-forme- (voisine de la plate-forme de stockage ) ; ce qui est représenté aux figures 12 et 15 dans îesquelies on voit à la fois un plateau auxiliaire 41 porteurs de siège en position supérieure active, et un plateau auxiliaire en stockage et destiné à être évacué vers la plate-forme voisine.The auxiliary trays can be carrying equipment for inter-intermittent use, therefore stored in the waiting position in the platforms, and capable of being brought with their carrying tray in the active position on the platform- (close to the storage platform); which is shown in Figures 12 and 15 in îesquelies we see both an auxiliary tray 41 seat carriers in the active upper position, and an auxiliary tray in storage and intended to be evacuated to the neighboring platform.
