Description

La présente invention concerne un bac à eau ou à sable destiné plus particulièrement aux activités éducatives et ludiques des jeunes enfants.The present invention relates to a water or sand tray intended more particularly for educational and recreational activities for young children.

On connaît des bacs à eau ou à sable, utilisés dans les maternelles ou les garderies, se présentant sous la forme d'un corps de bac disposé sensiblement au centre d'un plateau évidé formant table et supporté par un piètement adéquat. Ces bacs, utilisés essentiellement en intérieur, sont conçus de façon que la couronne du plateau évidé ménage, entre le bord périphérique du plateau et la partie centrale du bac contenant le liquide ou le milieu divisé, une zone de sécurité permettant aux enfants d'avoir accès en étendant le bras au contenu du bac, mais sans possibilité pour eux de se pencher au-dessus du contenu du bac et donc, éventuellement, d'y tomber par mégarde. Si ces dispositifs présentent toute satisfaction en ce qui concerne la sécurité et la souplesse d'utilisation, on a toutefois constaté que ladite couronne périphérique, formant ladite zone de sécurité mais également un plan de travail permettant de déposer divers objets, tels que des jouets, n'empêchait pas que de l'eau ou du sable, extraits du bac lors des manipulations desdits objets, ne recouvre progressivement cette couronne et ne tombe au-dehors du bac, avec les inconvénients afférents de maculage puis de nettoyage.Are known water or sand trays, used in kindergartens or daycares, being in the form of a tray body disposed substantially in the center of a hollowed-out tray forming a table and supported by a suitable base. These tanks, used mainly indoors, are designed so that the crown of the hollowed-out tray provides a safety zone between the peripheral edge of the tray and the central part of the tray containing the liquid or the divided medium. access by extending the arm to the contents of the tray, but without the possibility for them to lean over the contents of the tray and therefore, possibly, to fall into it inadvertently. If these devices are entirely satisfactory with regard to safety and flexibility of use, it has however been found that said peripheral crown, forming said safety zone but also a work surface making it possible to deposit various objects, such as toys, did not prevent that water or sand, extracted from the tank during the handling of said objects, progressively covers this crown and does not fall outside the tank, with the associated drawbacks of smearing and then cleaning.

Pour obvier à cet inconvénient il a été proposé un bac avec des bords périphériques inclinés vers l'intérieur du bac à la façon des anciens lavoirs et permettant ainsi une récupération des projections ou dépôts liquides ou sableux en provenance du bac en retour dans ce dernier. Toutefois, en raison de leur inclinaison, ces bords ne permettent alors plus de servir comme plan de travail, pour y déposer, en attente ou en utilisation, les divers objets flottants ou de fouissage utilisés en association avec le bac, et on a constaté que le dépôt par terre ou sur des dessertes annexes de ces objets présentait les mêmes inconvénients que les bacs à bord périphérique plan.To overcome this drawback, a tank has been proposed with peripheral edges inclined towards the inside of the tank in the manner of the old wash houses and thus allowing recovery of projections or liquid or sandy deposits coming from the tank back in the latter. However, because of their inclination, these edges then no longer make it possible to serve as a work surface, for depositing there, while waiting or in use, the various floating or digging objects used in association with the tank, and it has been found that depositing these objects on the ground or on ancillary trenches had the same disadvantages as the bins with a flat peripheral edge.

La présente invention a précisément pour objet un bac à eau ou à sable du type comprenant des bords inclinés vers l'intérieur et présentant en outre des moyens permettant de supporter de façon amovible des structures diverses au voisinage de la surface du produit entreposé dans le bac, à distance des bords du bac, en permettant ainsi une plus grande souplesse dans les possibilités de configuration et d'utilisation du bac, sans encombrer par des moyens de fixation latéraux les bords du bac, et en ménageant de ce fait, sur la périphérie de celui-ci notamment,lorsqu'il est rempli d'eau, unezone d'accès libre sans entraves.The present invention specifically relates to a water or sand tank of the type comprising edges inclined inward and further having means for removably supporting various structures in the vicinity of the surface of the product stored in the tank , at a distance from the edges of the tank, thus allowing greater flexibility in the possibilities of configuration and use of the tank, without cluttering up the edges of the tank by lateral fixing means, and thereby sparing the periphery in particular, when it is filled with water, a free access area without obstacles.

La présente invention a pour autre objet de proposer un bac-de ce type conformé de façon à présenter une rigidité et une tenue améliorées.Another object of the present invention is to provide a container of this type shaped so as to have improved rigidity and hold.

Pour ce faire, selon une caractéristique de la présente invention, le bac à eau ou à sable, du type comprenant un corps de bac comportant un fond et des parois latérales prolongées par des bords inclinés vers l'intérieur du corps de bac, comporte au moins un élément support indépendant susceptible d'être positionné en appui sur le fond pour supporter au moins une structure amovible au voisinage de la surface du produit entreposé dans le bac.To do this, according to a characteristic of the present invention, the water or sand tank, of the type comprising a tank body having a bottom and side walls extended by edges inclined towards the inside of the tank body, comprises at at least one independent support element capable of being positioned in abutment on the bottom to support at least one removable structure in the vicinity of the surface of the product stored in the tank.

Selon une caractéristique plus particulière de la présente invention, l'élément support est réalisé par empilage d'une pluralité d'éléments de hausse, le fond du bac présentant localement des moyens de montage coopérant avec des moyens correspondants à l'extrémité d'un des éléments supports pour permettre le montage amovible de ce dernier dans le bac.According to a more particular characteristic of the present invention, the support element is produced by stacking a plurality of raising elements, the bottom of the tank having locally mounting means cooperating with means corresponding to the end of a support elements to allow the removable mounting of the latter in the tray.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description suivante de modes de réalisation, donnés à titre illustratif mais nullement limitatif, faite en relation avec les dessins annexés sur lesquels :

  • La figure 1 est une vue schématique en perspective d'un bac selon la présente invention;
  • La figure 2 représente schématiquement, en coupe,divers agencements d'éléments supports selon la présente invention;
  • La figure 3 représente, en vue de côté, un mode de montage de structure amovible avec les éléments tronconiques de la figure 2; et
  • La figure 4 est une vue schématique du dessus du fond d'un corps de bac selon la présente invention.
Other characteristics and advantages of the present invention will emerge from the following description of embodiments, given by way of illustration but in no way limiting, made in relation to the appended drawings in which:
  • Figure 1 is a schematic perspective view of a tray according to the present invention;
  • FIG. 2 schematically represents, in section, various arrangements of support elements according to the present invention;
  • Figure 3 shows, in side view, a mounting method of removable structure with the frustoconical elements of Figure 2; and
  • Figure 4 is a schematic top view of the bottom of a tank body according to the present invention.

Comme représenté sur la figure 1, le bac selon la présente invention comprend un bac proprement dit, constitué d'un corps de bac 1, réalisé avantageusement d'une seule pièce, en acrylonitrile-butadiène-styrène (ABS), reposant sur deux panneaux latéraux 2, 2' formant piètement et entretoisés par des tubes 3.Comme on le voit mieux sur la figure 2, le corps de bac 1 comprend un fond 4, et des parois latérales 5, verticales, prolongées par des bords 6 inclinés vers l'inérieur du bac, et se raccordant continûment aux parois latérales 5, ces bords 6 étant avantageusement munis de nervures de rigidification 7.As shown in FIG. 1, the container according to the present invention comprises a container proper, consisting of a container body 1, advantageously made in one piece, made of acrylonitrile-butadiene-styrene (ABS), resting on two panels side 2, 2 'forming a base and braced by tubes 3. As can best be seen in FIG. 2, the tank body 1 comprises a bottom 4, and side walls 5, vertical, extended by edges 6 inclined towards the inside of the tank, and connecting continuously to the side walls 5, these edges 6 advantageously being provided with stiffening ribs 7.

On a représenté sur la figure 1, une plaque ou tablette 8, formant plan de travail, supportée par un élément support 9 de façon à s'étendre au-dessus de la surface 10- du produit entreposé dans le bac, à distance du bord voisin 6. On retrouve cette tablette 8 sur la partie gauche de la coupe de la figure 2.There is shown in Figure 1, a plate or shelf 8, forming a work surface, supported by a support element 9 so as to extend above the surface 10- of the product stored in the tray, away from the edge neighbor 6. This tablet 8 is found on the left side of the section in FIG. 2.

Dans ce mode de réalisation, l'élément support de la tablette 8 est constitué d'un empilement d'éléments de hausse 11 en forme de tronc de cône ou de gobelet, réalisés en matière plastique et gerbables pour former un empilement de hauteur variable selon les dimensions et le nombre des éléments 11. De la façon correspondante, également conformément à la présente invention, le fond 4 du corps de bac 1 présente localement des protubérances tronconiques 12 s'étendant vers l'intérieur du bac, de formes et de dimensions correspondants sensiblement aux éléments de hausse 11. Ceux-ci présentent, surtout pour une utilisation dans un bac à eau, des orifices 13 dans leur paroi latérale pour permettre l'introduction du produit entreposé dans le bac, ainsi qu'au moins un orifice traversant 14 dans la paroi transversale formant fond fermant la petite extrémité des éléments tronconiques 11, pour permettre notamment la solidarisation de l'élément supérieur avec la tablette 8 au moyen d'un pion, d'un rivet plastique, ou d'un système à vis ou à écrou 15.In this embodiment, the support element of the shelf 8 consists of a stack of elevation elements 11 in the form of a truncated cone or cup, made of plastic material and stackable to form a stack of variable height according to the dimensions and the number of the elements 11. Correspondingly, also in accordance with the present invention, the bottom 4 of the tank body 1 has locally frustoconical protrusions 12 extending towards the inside of the tank, of shapes and dimensions substantially corresponding to the elevating elements 11. These have, especially for use in a water tank, holes 13 in their side wall to allow the introduction of the product stored in the tank, as well as at least one through hole 14 in the transverse wall forming the bottom closing the small end of the frustoconical elements 11, to allow in particular the attachment of the upper element with the shelf 8 by means of a pin, a r plastic, or screw or nut system 15.

Au moins certains des éléments de hausse sont avantageusement pourvus, au niveau de leur extrémité de plus grand diamètre, d'une collerette radiale 16, percée d'orifices 17, comme figuré sur le montage de la partie centrale de la figure 2, afin d'autoriser des empilages tête-bêche, comme représenté sur cette partie centrale de la figure 2, où à l'inverse, un élément tronconique terminal supérieur, tel que celui référencé 110 sur la figure 2, pouvant servir de récipient annexe partiellement immergé dans le bac, par exemple pour l'entreposage de petits objets flottants.At least some of the raising elements are advantageously provided, at their end of larger diameter, with a radial flange 16, pierced with orifices 17, as shown in the assembly of the central part of FIG. 2, in order to d '' authorize head-to-tail stacking, as shown in this central part of Figure 2, where conversely, an upper frusto-conical element, such as that referenced 110 in Figure 2, which can serve as an annex container partially immersed in the bin, for example for the storage of small floating objects.

Comme représenté sur la figure-3, des éléments de hausse tronconiques 11' dépourvus de collerette radiale,peuvent avantageusement être munis de fentes longitudinales 18, permettant, par déformation élastique, un évasement plus prononcé de la partie de grand diamètre de l'élément tronconique et ainsi de moduler l'enfoncement des éléments de hausse les uns dans les autres,pour les rendre notamment difficilement démontables par les enfants,et pour réaliser,comme représenté sur la figure 3,au moyen d'un même nombre déterminé d'éléments empilés,des niveaux,émergeant ou immergés, différents de l'élément supérieur,permettant le montage de plaques inclinées 8' formant toboggan,ces dernières étant avantageusement réalisées en une matière plastique semi-souple.As shown in Figure-3, frustoconical rising elements 11 'devoid of radial flange, can advantageously be provided with longitudinal slots 18, allowing, by elastic deformation, a more pronounced flaring of the large diameter portion of the element tron conical and thus modulate the insertion of the rising elements into each other, to make them particularly difficult to dismantle by children, and to achieve, as shown in Figure 3, using the same determined number of elements stacked, levels, emerging or submerged, different from the upper element, allowing the mounting of inclined plates 8 'forming a slide, the latter being advantageously made of a semi-flexible plastic.

On a représenté sur la partie droite de la figure 2, d'autres modes de réalisation des éléments supports selon la présente invention. Ici, le fond 4 du corps de bac est formé avec des évidements en creux cylindriques ou prismatiques pour recevoir a emmanchement des tétons de forme correspondante 20, formés sur une face d'un élément de hausse 111 de forme cylindrique ou prismatique, l'autre face de l'élément de hausse 111 présentant un évidement correspondant à l'évidement 19 pour recevoir le téton d'un autre élément de hausse et favoriser ainsi leur empilage. Comme également représenté sur la partie droite de la figure 2, les éléments de hausse, tels que ceux repérés 112 et 113, peuvent être constitués en un matériau magnétique sous la forme de disques aimantés empilables de façon cohérente les uns sur les autres, pour supporter, par exemple, une structure supérieure 114, de forme ou de dimensions déterminées quelconques.Other embodiments of the support elements according to the present invention are shown on the right-hand side of FIG. 2. Here, the bottom 4 of the tank body is formed with cylindrical or prismatic hollow recesses for receiving, with fitting, pins of corresponding shape 20, formed on one face of an elevating element 111 of cylindrical or prismatic shape, the other face of the raising element 111 having a recess corresponding to the recess 19 for receiving the stud of another raising element and thus promoting their stacking. As also shown on the right-hand side of FIG. 2, the lifting elements, such as those marked 112 and 113, can be made of a magnetic material in the form of magnetic disks which can be stacked coherently on each other, to support , for example, an upper structure 114, of any given shape or size.

On conçoit que les agencements représentés sur la figure 2 permettent de répartir au mieux sur la surface libre du bac différentes structures amovibles 8, 110 ou 114 émergées, au ras de la surface 10 ou immergées, en multipliant au gré des besoins les possibilités, tout en gardant libre la zone périphérique de la surface 10 du produit exposé entreposé dans le bac au voisinage des parois 5 et des bords 6, en permettant notamment à un enfant faisant le tour du bac, de propulser à la main un petit bateau ou un objet flottant sans se heurter à des structures s'étendant à partir du bord vers l'intérieur du bac qu'il ne pourrait contourner vers l'intérieur du bac en raison précisément de la largeur des garde-fous constitués par les ailes des bords inclinés 6. Cet agencement permet également à une maîtresse d'entreposer hors de portée des enfants des objets sur une structure amovible située au centre du bac.It will be appreciated that the arrangements shown in FIG. 2 make it possible to distribute as best as possible over the free surface of the tank various removable structures 8, 110 or 114 emerging, flush with the surface 10 or immersed, by multiplying as required the possibilities, all keeping free the peripheral zone of the surface 10 of the exposed product stored in the tank in the vicinity of the walls 5 and the edges 6, by allowing in particular a child going around the tank, to propel by hand a small boat or an object floating without colliding with structures extending from the edge towards the inside of the tank which it could not bypass towards the inside of the tank precisely because of the width of the guard rails formed by the wings of the inclined edges 6. This arrangement also allows a teacher to store out of reach of children objects on a removable structure located in the center of the tray.

On a représenté sur la figure 4, une vue de dessus du fond 4 du bac 1 selon la présente invention. Ce fond,qui peut être plat ou légèrement incurvé, est normalement légèrement incliné vers une ouverture ou bonde d'évacuation 21. Les formations en creux ou en relief 12 du fond du bac, permettant le montage des éléments de hausse, réalisent une certaine rigidification-du fond du bac, mais qui n'est toutefois pas suffisante pour les bacs de grande capacité. Un nervurage tant transversal que longitudinal du fond présenterait les inconvénients de retenir dans les rainures correspondantes certaines quantités du produit entreposé dans le bac, empêchant ainsi une parfaite vidange de celui-ci. Conformément à la présente invention, le fond du bac présente des séries alternées de nervures 22 et 22', saillant vers l'intérieur du bac, chaque nervure s'étendant sur une portion de la largeur du fond alternativement à partir d'une des deux parois latérales en regard du bac définissant cette lar÷ geur. Comme on le voit sur les figures 2 et 4, ces nervures 22 ou 22' présentent une section transversale sensiblement en forme de V inversé et de hauteur décroissante depuis la paroi latérale à partir de laquelle elles s'étendent.There is shown in Figure 4, a top view of the bottom 4 of the tray 1 according to the present invention. This bottom, which can be flat or slightly curved, is normally slightly inclined towards an opening or discharge plug 21. The hollow or raised formations 12 of the bottom of the tank, allowing the mounting of the rising elements, achieve a certain stiffening - from the bottom of the tank, but which is however not sufficient for large capacity tanks. Ribbing both transversely and longitudinally of the bottom would have the drawbacks of retaining in the corresponding grooves certain quantities of the product stored in the tank, thus preventing perfect emptying of the latter. According to the present invention, the bottom of the tank has alternating series of ribs 22 and 22 ', projecting towards the inside of the tank, each rib extending over a portion of the width of the bottom alternately from one of the two facing side walls of the tray defining this lar ÷ geur. As seen in Figures 2 and 4, these ribs 22 or 22 'have a cross section substantially in the shape of an inverted V and decreasing in height from the side wall from which they extend.

Quoique la présente invention ait été décrite en relation avec des modes de réalisation particuliers, elle ne s'en trouve pas limitée mais est au contraire susceptible de modifications et de variantes. En particulier, les éléments supports peuvent être pré-associés à plusieurs pour un montage multipoints sur les formations en relief ou en creux du fond du bac, par exemple, pour réaliser des structures de trépied, les éléments de hausse inférieurs, tels que l'élément 111, pouvant être laissés à demeure dans le fond du bac, par exemple par emmanchement dur, pour permettre un empilement plus aisé des seuls éléments supérieurs lorsque le bac est déjà rempli d'eau.Although the present invention has been described in relation to particular embodiments, it is not limited thereto but is on the contrary subject to modifications and variants.
