On a représenté sur les figures 1 et 2 un local 2 de magasin, proposant à la vente en exemple des fleurs, dans lequel est agencé un présentoir 4 selon l'invention.There is shown in Figures 1 and 2 a local store 2, offering for sale as an example of flowers, in which is arranged a display 4 according to the invention.

Le local 2 comporte une ouverture 6 de forme générale rectangulaire, ménagée dans une devanture 7 sensiblement verticale, destinée à être fermée par une vitrine 8 escamotable.The room 2 has an opening 6 of generally rectangular shape, formed in a substantially vertical storefront 7, intended to be closed by a retractable display case 8.

La vitrine 8 comporte deux volets 10,12, de forme générale rectangulaire, dont les bords adjacents 10A,12A sont articulés entre eux autour d'un axe horizontal, et dont les bords opposés 10B,12B sont disposés dans le plan de l'ouverture 6, le bord 10B du volet supérieur 10 étant articulé autour d'un axe fixe horizontal, au voisinage du bord supérieur de l'ouverture 6, et le bord 12B du volet inférieur 12 étant déplaçable en translation verticale dans des glissières 14 solidaires des bords de l'ouverture 6.The display case 8 comprises two flaps 10, 12, of generally rectangular shape, the adjacent edges 10A, 12A of which are hinged together around a horizontal axis, and the opposite edges of which 10B, 12B are arranged in the plane of the opening 6, the edge 10B of the upper flap 10 being articulated about a horizontal fixed axis, in the vicinity of the upper edge of the opening 6, and the edge 12B of the lower flap 12 being movable in vertical translation in slides 14 integral with the edges of the opening 6.

De cette façon, la vitrine 8 peut être dépliée de manière à fermer l'ouverture 6, comme cela est représenté sur la figure 1, ou bien repliée, de manière à former un auvent dans la partie supérieure de l'ouverture 6, comme cela est représenté sur la figure 2.In this way, the display case 8 can be unfolded so as to close the opening 6, as shown in FIG. 1, or folded over, so as to form a canopy in the upper part of the opening 6, like this is shown in figure 2.

Le repliage et le dèpliage de la vitrine 8 sont effectués par des moyens manuels ou motorisés de type classique.The folding and unfolding of the display case 8 is carried out by manual or motorized means of conventional type.

Lorsque l'ouverture 6 du local est obturée par la vitrine 8, le présentoir 4 est dans une position repliée telle que son encombrement au sol soit réduit tout en maintenant la présentation commerciale des produits.When the opening 6 of the room is closed by the display case 8, the display unit 4 is in a folded position such that its size on the ground is reduced while maintaining the commercial presentation of the products.

Lorsque la vitrine 8 est repliée, de manière à dégager l'ouverture 6, le présentoir 4 s'étend à travers l'ouverture 6, dans une position déployée propice à la présentation des marchandises.When the display case 8 is folded, so as to release the opening 6, the display unit 4 extends through the opening 6, in a deployed position suitable for the presentation of the goods.

On décrira maintenant plus en détail un présentoir 4 selon un premier mode de réalisation de l'invention, en regard des figures 3 à 8.A display 4 will now be described in more detail according to a first embodiment of the invention, with reference to FIGS. 3 to 8.

En se référant plus particulièrement à la figure 3, on voit que le présentoir 4 comporte un cadre principal 16 comportant deux montants latéraux 18 reliés par deux traverses 20, ces éléments étant fabriqués par exemple avec des cornières métalliques et/ou des fers plats soudés entre eux.Referring more particularly to FIG. 3, it can be seen that the display unit 4 comprises a main frame 16 comprising two lateral uprights 18 connected by two crosspieces 20, these elements being produced for example with metal angles and / or flat bars welded between them.

Le présentoir 4 comporte de plus deux cadres secondaires 22, dont un seul est représenté sur la figure 3, formant supports pour des étagères 24 horizontales ou, en variante, inclinées par rapport à un plan horizontal en étant parallèles entre elles. Ces étagères 24 sont fabriquées, par exemple, en caillebotis métallique, en aggloméré stratifié en verre feuilleté sablé, etc... destinées à présenter diverses marchandises.The display 4 further comprises two secondary frames 22, only one of which is shown in FIG. 3, forming supports for shelves 24 horizontal or, as a variant, inclined with respect to a horizontal plane being parallel to one another. These shelves 24 are made, for example, of metal gratings, of laminated chipboard in laminated sandblasted glass, etc. intended to display various goods.

Les cadres secondaires 22 comportent des montants 26, parallèles à ceux du cadre principal 16, en forme de plaques, par exemple en tôle, reliés entre eux par des traverses 28, en forme de profilés, par exemple métalliques, délimitant des bords d'appui pour les étagères 24.The secondary frames 22 comprise uprights 26, parallel to those of the main frame 16, in the form of plates, for example of sheet metal, connected together by crosspieces 28, in the form of profiles, for example of metal, delimiting support edges for shelves 24.

Chaque cadre secondaire 22 comporte au moins une étagère 24, de préférence deux étagères, comme dans l'exemple décrit, décalées verticalement et horizontalement entre elles.Each secondary frame 22 comprises at least one shelf 24, preferably two shelves, as in the example described, offset vertically and horizontally between them.

Les cadre secondaires 22 sont destinés à être portés chacun par une broche horizontale 30,32 correspondante montée pivotante autour de son axe sur les deux montants 18 du cadre principal 16.The secondary frames 22 are intended to be each carried by a corresponding horizontal pin 30, 32 pivotally mounted around its axis on the two uprights 18 of the main frame 16.

Comme cela est représenté à la figure 4, qui montre le cas particulier de la broche 30, les extrémités des broches 30,32 tourillonnent dans des paliers 34 ménagés dans les montants 18 du cadre principal.As shown in FIG. 4, which shows the particular case of pin 30, the ends of pins 30, 32 are journalled in bearings 34 formed in the uprights 18 of the main frame.

Chacune des extrémités d'une broche 30,32 comporte un flasque 36 circulaire et une roue dentée 38 centrés sur l'axe de cette broche et fixés par des moyens connus sur cette dernière.Each end of a spindle 30,32 comprises a circular flange 36 and a toothed wheel 38 centered on the axis of this spindle and fixed by known means on the latter.

Les montants 26 de chaque cadre secondaire 22 comportent des évidements 40 de positionnement sur la broche 30,32 correspondante et sont destinés à être fixés sur les flasques 36 par des moyens connus.The uprights 26 of each secondary frame 22 have recesses 40 for positioning on the corresponding pin 30, 32 and are intended to be fixed to the flanges 36 by known means.

Dans l'exemple décrit, les flasques 36 sont fixés sur les broches 30,32 par soudage, les roues dentées 38 et les montants 26 des cadres secondaires étant fixés sur les flasques 36 par des vis 42.In the example described, the flanges 36 are fixed to the pins 30, 32 by welding, the toothed wheels 38 and the uprights 26 of the secondary frames being fixed to the flanges 36 by screws 42.

Les deux roues dentées 38 disposées à proximité de chaque montant 18 du cadre principal sont accouplées entre elles par une chaîne 44.The two toothed wheels 38 placed near each upright 18 of the main frame are coupled together by a chain 44.

Les chaînes 44 et les roues 38 permettent de stabiliser angulairement les étagères 24 comme cela sera décrit ultérieurement.The chains 44 and the wheels 38 allow the shelves 24 to be angularly stabilized as will be described later.

En se référant à nouveau à la figure 3, on voit que la broche 30 est reliée à deux châssis fixes latéraux 46, disposés de part et d'autre des montants du cadre principal, de manière à former un arbre d'articulation du cadre principal autour de l'axe horizontal de cet arbre.Referring again to FIG. 3, it can be seen that the pin 30 is connected to two lateral fixed frames 46, arranged on either side of the uprights of the main frame, so as to form an articulation shaft of the main frame around the horizontal axis of this tree.

Sur la figure 3, on a également représenté un pied d'appui 48 du cadre principal, de hauteur réglable, solidaire de la traverse 20 opposée à l'arbre d'articulation 30 de ce cadre.In Figure 3, there is also shown a support leg 48 of the main frame, of adjustable height, integral with the cross member 20 opposite the articulation shaft 30 of this frame.

On décrira maintenant les châssis 46 plus en détail en regard des figures 5 et 6 représentant un de ces châssis.The frames 46 will now be described in more detail with reference to FIGS. 5 and 6 showing one of these frames.

Les châssis 46 comportent des moyens de déplacement du cadre principal 16 entre une position d'encombrement au sol réduit, telle que représentée aux figures 1 et 7, dans laquelle le cadre principal 16 est sensiblement vertical, et une position de présentation telle que représentée aux figures 2 et 8.The chassis 46 include means for moving the main frame 16 between a space-saving position on the reduced floor, as shown in FIGS. 1 and 7, in which the main frame 16 is substantially vertical, and a presentation position as shown in Figures 2 and 8.

Les moyens de déplacement du cadre principal comprennent des moyens 50 de déplacement vertical de l'arbre d'articulation 30 et des moyens 52 de basculement du cadre principal 16 autour de cet arbre d'articulation 30, les moyens 50 de déplacement vertical et les moyens 52 de basculement étant accouplés entre eux.The means for moving the main frame comprise means 50 for vertical displacement of the articulation shaft 30 and means 52 for tilting the main frame 16 around this articulation shaft 30, the means 50 for vertical displacement and the means 52 of tilting being coupled together.

Les moyens 50 de déplacement vertical comprennent deux coulisseaux 54, chacun d'eux étant fixé à une des extrémités de l'arbre d'articulation 30 et étant monté dans un châssis 46 correspondant en étant déplaçable en translation verticale au moyen d'une tige filetée d'entraînement verticale 56 coopérant par vissage avec une extrémité 58 formant écrou du coulisseau 54.The means 50 for vertical displacement comprise two slides 54, each of them being fixed to one of the ends of the articulation shaft 30 and being mounted in a corresponding chassis 46 while being displaceable in vertical translation by means of a threaded rod vertical drive 56 cooperating by screwing with one end 58 forming a nut of the slide 54.

De préférence, chaque coulisseau 54 comporte des rouleaux 54A coopérant avec une glissière verticale 59 portée par le châssis 46 correspondant.Preferably, each slide 54 comprises rollers 54A cooperating with a vertical slide 59 carried by the corresponding frame 46.

Sur la figure 6, on a représenté des moyens 60 à engrenage, de type connu, destinés à accoupler la tige filetée 56 du châssis 46 représenté sur cette figure avec un moteur 61.In FIG. 6, there is shown gear means 60, of known type, intended to couple the threaded rod 56 of the chassis 46 shown in this figure with a motor 61.

On a également représenté sur cette figure des moyens 62 à engrenage, de type connu, destinés à accoupler la tige filetée 56 avec des moyens d'entraînement manuel classiques, ainsi que des moyens à engrenage comportant un arbre 64 d'accouplement de la tige filetée 56 du châssis 46 représenté sur la figure avec la tige filetée du châssis opposé.Also shown in this figure are gear means 62, of known type, intended to couple the threaded rod 56 with conventional manual drive means, as well as gear means comprising a shaft 64 for coupling the threaded rod. 56 of the chassis 46 shown in the figure with the threaded rod of the opposite chassis.

L'arbre d'articulation 30, solidaire des coulisseaux 54 déplaçables uniquement en translation verticale, est immobilisé en rotation par rapport à son axe, si bien que la broche 32, accouplée avec l'arbre d'articulation 30 par les chaînes 44 engrenant avec les roues dentées 38, est également immobilisée en rotation par rapport à son axe. Par conséquent, les positions angulaires des étagères 24 sont conservées indépendamment des mouvements du cadre principal 16.The articulation shaft 30, integral with the slides 54 displaceable only in vertical translation, is immobilized in rotation relative to its axis, so that the spindle 32, coupled with the articulation shaft 30 by the chains 44 meshing with the toothed wheels 38, is also immobilized in rotation relative to its axis. Consequently, the angular positions of the shelves 24 are preserved independently of the movements of the main frame 16.

En variante, les roues dentées 38 accouplées entre elles par les chaînes 44 peuvent être remplacées par des roues à gorge formant poulies, accouplées entre elles par des courroies.As a variant, the toothed wheels 38 coupled together by the chains 44 can be replaced by grooved wheels forming pulleys, coupled together by belts.

Les moyens 52 de basculement du cadre principal 16 comprennent deux bras de basculement 66, chacun d'eux étant porté par le châssis 46 correspondant.The means 52 for tilting the main frame 16 comprise two tilt arms 66, each of them being carried by the corresponding chassis 46.

Chaque bras de basculement 66 comporte une première extrémité 66A montée pivotante sur le châssis 46 autour d'un axe X parallèle à l'arbre d'articulation 30, et une seconde extrémité 66B, munie d'un patin articulé à rouleaux 68, coulissant sur un profilé 70, formant glissière, solidaire d'un montant 18 correspondant du cadre principal.Each tilting arm 66 has a first end 66A pivotally mounted on the chassis 46 around an axis X parallel to the articulation shaft 30, and a second end 66B, provided with an articulated roller pad 68, sliding on a profile 70, forming a slide, integral with a corresponding amount 18 of the main frame.

Ce profilé 70 est représenté en traits mixtes sur la figure 5 et en traits pleins notamment sur les figures 4, 7 et 8.This profile 70 is shown in dashed lines in FIG. 5 and in solid lines in particular in FIGS. 4, 7 and 8.

Le bras 66 est accouplé avec la tige filetée 56, et par conséquent avec le moteur 61, par l'intermédiaire de moyens 72 à engrenage, de type connu, comportant une roue dentée 74 engrènant avec une vis sans fin 76 agencée sur la tige filetée 56.The arm 66 is coupled with the threaded rod 56, and consequently with the motor 61, by means of gear 72, of known type, comprising a toothed wheel 74 meshing with an endless screw 76 arranged on the threaded rod 56.

Chaque châssis 46 comportent également une lame ressort 78, destinée à s'opposer aux effets du poids du cadre principal 16 et de son chargement lors de ses déplacements, et un ressort de traction 80 destiné à assister le déplacement de l'arbre d'articulation 30 vers sa position la plus haute.Each frame 46 also includes a leaf spring 78, intended to oppose the effects of the weight of the main frame 16 and of its loading during its movements, and a tension spring 80 intended to assist the movement of the articulation shaft. 30 to its highest position.

La lame ressort 78 comporte une première extrémité fixée sur le châssis 46 et une seconde extrémité coulissant le long du bras de basculement 66 en étant plaquée élastiquement contre ce dernier.The leaf spring 78 has a first end fixed to the chassis 46 and a second end sliding along the tilting arm 66 while being pressed elastically against the latter.

Le ressort de traction 80 comporte une première extrémité fixée sur le châssis et une seconde extrémité reliée au coulisseau 54.The tension spring 80 has a first end fixed to the chassis and a second end connected to the slide 54.

On décrira maintenant le fonctionnement du présentoir 4 selon le premier mode de réalisation de l'invention, en regard des figures 7 et 8.The operation of the display unit 4 according to the first embodiment of the invention will now be described, with reference to FIGS. 7 and 8.

Initialement, la vitrine 8 est en position fermée et le cadre principal 16 du présentoir 4 est dans une position sensiblement verticale permettant de réduire l'encombrement au sol du présentoir 4, comme cela est représenté sur la figure 7.Initially, the display case 8 is in the closed position and the main frame 16 of the display unit 4 is in a substantially vertical position making it possible to reduce the size on the ground of the display unit 4, as shown in FIG. 7.

Le cadre principal 16 est immobilisé dans cette position verticale par les bras de basculement 66 qui sont immobilisès en appui contre les glissières 70 du cadre principal et par des butées 82, solidaires des châssis 46, coopérant avec la traverse 20 du cadre principal la plus proche de l'arbre d'articulation 30.The main frame 16 is immobilized in this vertical position by the tilting arms 66 which are immobilized in abutment against the slides 70 of the main frame and by stops 82, integral with the frames 46, cooperating with the crosspiece 20 of the nearest main frame of the articulation shaft 30.

Dans la position du présentoir 4 représentée à la figure 7, les cadres secondaires 22 sont disposés l'un au dessus de l'autre, si bien que des marchandises disposées sur les étagères 24 peuvent être vues de l'extérieur du local, à travers la vitrine 8.In the position of the display 4 shown in Figure 7, the secondary frames 22 are arranged one above the other, so that goods arranged on the shelves 24 can be seen from outside the room, through showcase 8.

Pour déplacer le présentoir 4 vers sa position déployée de présentation telle que représentée sur la figure 8, après ouverture de la vitrine 8, on commande soit le moteur 61 à l'aide de moyens connus, soit les moyens d'entraînement manuel 62 de manière à provoquer simultanément la montée verticale de l'arbre d'articulation 30 et le basculement du cadre principal 16 autour de cet arbre d'articulation, sous l'effet du déplacement en translation verticale des coulisseaux 54 et du pivotement des bras de basculement 66 dans le sens horaire en considérant les figures 7 et 8.To move the display 4 to its deployed presentation position as shown in FIG. 8, after opening the display case 8, either the motor 61 is controlled using known means, or the manual drive means 62 so to simultaneously cause the vertical rise of the articulation shaft 30 and the tilting of the main frame 16 around this articulation shaft, under the effect of the displacement in vertical translation of the slides 54 and the pivoting of the tilting arms 66 in clockwise considering Figures 7 and 8.

Bien entendu, les moyens d'accouplement des tiges filetées 56 d'entraînement des coulisseaux 54 et des bras de basculement 66 sont dimensionnés de manière à synchroniser les mouvements de ces éléments.Of course, the means for coupling the threaded rods 56 for driving the slides 54 and the arms tilt 66 are dimensioned so as to synchronize the movements of these elements.

Lorsque le cadre principal 16 se déplace vers sa position de présentation, il bascule sous l'effet de son propre poids autour de l'arbre d'articulation 30, les bras de basculement 66 ayant pour fonction dans ce cas de s'opposer au poids du cadre principal 16 et de contrôler ainsi son basculement.When the main frame 16 moves to its presentation position, it rocks under the effect of its own weight around the articulation shaft 30, the tilting arms 66 having the function in this case of opposing the weight of the main frame 16 and thus control its tilting.

On notera que le sens initial de basculement du cadre principal 16 est imposé par les butées 82 coopérant avec la traverse 20 de ce cadre.Note that the initial direction of tilting of the main frame 16 is imposed by the stops 82 cooperating with the cross member 20 of this frame.

Par ailleurs, le soulèvement de l'arbre d'articulation 30 est assisté initialement par les ressorts de traction 80.Furthermore, the lifting of the articulation shaft 30 is initially assisted by the tension springs 80.

La course des bras de basculement 66 est limitée par des butées 84, solidaires des châssis 46, coopérant avec ces bras 66 lorsque le cadre est dans sa position de présentation telle que représentée à la figure 8.The stroke of the tilting arms 66 is limited by stops 84, integral with the chassis 46, cooperating with these arms 66 when the frame is in its presentation position as shown in FIG. 8.

Dans cette position, le cadre principal 16 est en appui sur le sol, à l'extérieur du local 2, par l'intermédiaire du pied réglable 48. Par ailleurs, les étagères 24 sont disposées en gradins de façon propice à l'exposition de marchandises, deux étagères supérieures 24 étant disposées à l'intérieur du local 2 et deux étagères inférieures 24 étant disposées à l'extérieur de ce local.In this position, the main frame 16 is supported on the ground, outside the room 2, by means of the adjustable foot 48. Furthermore, the shelves 24 are arranged in steps so as to be exposed to goods, two upper shelves 24 being arranged inside the room 2 and two lower shelves 24 being arranged outside the room.

En dimensionnant la vitrine 8 de façon appropriée, il est possible de refermer celle-ci alors que le présentoir 4 est en position déployée de manière que la vitrine 8 fermée sépare les étagères intérieures des étagères extérieures.By appropriately dimensioning the display case 8, it is possible to close the latter while the display unit 4 is in the deployed position so that the closed display case 8 separates the interior shelves from the exterior shelves.

La remise en place du présentoir 4 dans sa position représentée à la figure 7 se fait en commandant une action inverse à celle précédemment décrite du moteur 61. Dans ce cas, les bras de basculement 66 poussent le cadre principal 16 vers sa position verticale.The repositioning of the display unit 4 in its position shown in FIG. 7 is done by commanding an action opposite to that previously described of the motor 61. In this case, the tilting arms 66 push the main frame 16 towards its vertical position.

On notera que pendant les déplacements du cadre principal 16 les effets dus au poids de ce cadre ont été partiellement contrés par les lames ressort 78.It will be noted that during the movements of the main frame 16 the effects due to the weight of this frame were partially countered by the spring blades 78.

En variante, le moteur 61 peut être remplacé ou relayé en cas de panne par des moyens d'entraînement manuel.As a variant, the motor 61 can be replaced or relayed in the event of a breakdown by manual drive means.

On décrira maintenant un second mode de réalisation de l'invention en regard des figures 9 à 11.A second embodiment of the invention will now be described with reference to FIGS. 9 to 11.

Sur ces figures, les éléments analogues à ceux des figures 1 à 8 sont désignés par des références identiques.In these figures, elements similar to those of Figures 1 to 8 are designated by identical references.

Le présentoir 4 représenté à la figure 9 diffère de celui décrit précédemment en ce qu'il comporte des moyens 50A de déplacement vertical de l'arbre d'articulation 30 comportant deux ensembles 86 de biellettes délimitant des parallélogrammes articulés, chacun de ces ensembles 86 étant portés par un châssis 46.The display 4 shown in Figure 9 differs from that described above in that it comprises means 50A for vertical displacement of the articulation shaft 30 comprising two sets 86 of rods delimiting articulated parallelograms, each of these sets 86 being carried by a chassis 46.

Les extrémités de l'arbre d'articulation 30 sont fixées à des doubles biellettes 88 délimitant des côtés mobiles verticaux des parallélogrammes 86.The ends of the articulation shaft 30 are fixed to double links 88 delimiting vertical movable sides of the parallelograms 86.

En se référant en particulier aux figures 10 et 11, on voit que le côté vertical du parallélogramme 86 opposé à la double biellette 88 est fixe et s'étend entre deux axes X1,X2, parallèles à l'arbre d'articulation 30, autour desquels pivotent deux biellettes 90,92 délimitant les côtés adjacents aux côtés verticaux du parallélogramme 86.With particular reference to FIGS. 10 and 11, it can be seen that the vertical side of the parallelogram 86 opposite the double link 88 is fixed and extends between two axes X1, X2, parallel to the articulation shaft 30, around which pivot two rods 90, 92 defining the sides adjacent to the vertical sides of the parallelogram 86.

Le bras de basculement 66 représenté aux figures 10 et 11 est accouplé au moteur 61 par des moyens 94 à engrenage, de type connu, comprenant notamment une roue dentée 96 engrenant avec une vis sans fin 98 accouplée avec l'arbre du moteur 61 (voir figure 11).The tilting arm 66 shown in FIGS. 10 and 11 is coupled to the motor 61 by gear means 94, of known type, comprising in particular a toothed wheel 96 meshing with an endless screw 98 coupled to the shaft of the motor 61 (see figure 11).

Par ailleurs, une des biellettes pivotantes 92 est accouplée avec le bras de basculement 66 correspondant par des moyens 100 à engrenage de type connu.Furthermore, one of the pivoting links 92 is coupled with the corresponding tilting arm 66 by means 100 of known type of gear.

En variante, les deux côtés parallèles fixe et mobile du parallélogramme peuvent être inclinés suivant un angle quelconque par rapport à la verticale.As a variant, the two fixed and movable parallel sides of the parallelogram can be inclined at any angle relative to the vertical.

On a également représenté, sur la figure 11, des moyens d'accouplement des bras de basculement 66 de chaque châssis 46 comportant notamment un arbre 102 à engrenage engrenant avec la vis sans fin 98.FIG. 11 also shows means for coupling the tilting arms 66 of each chassis 46 comprising in particular a shaft 102 with gear meshing with the worm 98.

Chaque châssis 46 comporte de plus un ressort de poussée 104 destiné à assister le déplacement de l'arbre d'articulation 30 vers sa position la plus haute.Each chassis 46 further comprises a thrust spring 104 intended to assist the movement of the articulation shaft 30 towards its highest position.

A cet effet, le ressort 104 est enfilé sur une tige verticale 106, portée par le châssis 46, et comporte une extrémité en contact avec la biellette pivotante 92 du parallélogramme.To this end, the spring 104 is threaded on a vertical rod 106, carried by the chassis 46, and has one end in contact with the pivoting link 92 of the parallelogram.

Le fonctionnement du présentoir 4 selon le second mode de réalisation est analogue à celui du présentoir selon le premier mode de réalisation et ne sera donc pas décrit par la suite.The operation of the display unit 4 according to the second embodiment is similar to that of the display unit according to the first embodiment and will therefore not be described below.

L'invention comporte de nombreux avantages.The invention has many advantages.

Le présentoir selon l'invention peut être utilisé avantageusement pour procurer à de nombreux magasins l'étalage rationnel qui leur manque. Il permet de supprimer les manipulations fastidieuses des étalages de type classique. Il offre de plus une très grande flexibilité de présentation et de stockage des marchandises.The display according to the invention can be used advantageously to provide many stores with the rational display they lack. It eliminates the tedious handling of displays of conventional type. It also offers great flexibility in the presentation and storage of goods.

Lorsque le présentoir selon l'invention est en position d'encombrement au sol réduit pour le stockage des marchandises disposées sur le présentoir, ces marchandises sont visibles à travers la vitrine du magasin, en permettant ainsi de maintenir l'attraction de la clientèle pendant les périodes de fermeture du magasin.When the display unit according to the invention is in a space-saving position on the reduced floor for the storage of the goods arranged on the display unit, these goods are visible through the store window, thereby making it possible to maintain the attraction of the customers during the store closing times.
