Description

La présente invention se réfère aux éléments pour jeux de construction à encastrement du type présentant généralement, d'un côté, des reliefs de jonction et, du côté opposé, des cavités aptes à recevoir les reliefs de jonction d'un élément analogue.The present invention relates to elements for building construction sets of the type generally having, on one side, junction reliefs and, on the opposite side, cavities suitable for receiving the junction reliefs of a similar element.

Dans les formes plus répandues, ces éléments ont une forme à coque, c'est-à-dire a boîte ouverte, et les cavités destinées à recevoir les reliefs de jonction d'un autre élément sont définies par les mêmes parois latérales de l'élément à coque, lesquelles présentent une certaine déformabilité élastique qui est utilisée pour obtenir un frottement opportun dans la jonction entre deux éléments, sans exiger une précision excessive dans la construction. Mais un tel système de jonction ne permet pas, par sa nature même,la réalisation d'éléments en forme de boîte fermée, qui serait opportune pour des éléments de dimensions considérables, destinés aux usagers plus jeunes.In the most widespread forms, these elements have a shell shape, that is to say an open box, and the cavities intended to receive the reliefs of junction of another element are defined by the same side walls of the shell element, which have a certain elastic deformability which is used to obtain timely friction in the junction between two elements, without requiring excessive precision in construction. However, such a joining system does not, by its very nature, allow the production of elements in the form of a closed box, which would be appropriate for elements of considerable dimensions, intended for younger users.

Le système de jonction décrit dans le brevet italien No. 739.869, dans lequel les reliefs de jonction d'un élément sont constitués par des groupes de quattre goujons qui peuvent être accouplés dans une cavité substantiellement circulaire de la partie opposée d'un élément analogue, se prête à la réalisation d'éléments à boite fermée,puisque dans ce cas la stabilité de la jonction n'est pas confiée à la déformabilité des parois mais à un juste degré d4int.erférence entre les cotes périphériques du groupe de goujons et celles des cavités, et on peut réaliser les goujons et les cavitéssur les parois opposées d'une structure à boîte fermée. Toutefois, si l'on applique ce système à des éléments de dimensions considérables, on constate que l'inégalité des contractions du matériel thermoplastique injectée qui est employé dans la construction des éléments, assume une telle importance qu'elle ne permet pas d'assurer una stabilité uniforme des différents encastrements, non seulement, mais parfois elle compromet aussi la possibilité d'un correct accouplement entre éléments ayant des dimensions multiples de celles d'un élément modulaire unitaire. En outre, des phéno- ménes de grippage et d'usure des jonction se vérifient facilement si l'on emploie des résines, telles que.le chlorure de polyvinyle, qui sont d'autre part désirables soit pour des raisons économiques que parce qu'elles se prêtent bien à la pigmentation et se présentent très favorablement à la vue et au toucher.The joining system described in Italian Patent No. 739,869, in which the junction reliefs of an element are formed by groups of four studs which can be coupled in a substantially circular cavity of the opposite part of an analogous element, lends itself to the production of elements with a closed box, since in this case the stability of the junction is not entrusted to the deformability of the walls but to a fair degree d4int.erference between the peripheral dimensions of the group of studs and those of the cavities, and studs and cavities can be made on opposite walls of a closed box structure. However, if one applies this system to elements of considerable dimensions, one notes that the inequality of the contractions of the injected thermoplastic material which is used in the construction of the elements, assumes such an importance that it does not make it possible to ensure a uniform stability of the different recesses, not only, but sometimes it also compromises the possibility of a correct coupling between elements having dimensions multiple of those of a unitary modular element. In addition, binding and wear phenomena of the joints are easily verified if resins, such as polyvinyl chloride, are used which are desirable either for economic reasons or because they lend themselves well to pigmentation and appear very favorably to the sight and to the touch.

Le but de la présente invention est celui de remédier aux susdits inconvénients des éléments connus pour constructions à encastrement et de permettre la réalisation d'éléments de forme à boite fermée, d'une fabrication économique et qui, aussi dans les plus grandes dimensions, assurent une uniformité et stabilité appropriée des jonctions à encastrement.The object of the present invention is to remedy the above drawbacks of the known elements for built-in constructions and to allow the production of closed box shaped elements, of economical manufacture and which, also in the largest dimensions, ensure uniformity and appropriate stability of the embedded joints.

L'idée de linvention est celle de réaliser des groupes de reliefs de jonction sous forme de composants fabriqués séparément, appliqués au corps principal de chaque élément qui forme sa structure à boîte et qui présente les cavités pour l'encastrement des reliefs de jonction d'un élément analogue.The idea of the invention is that of making groups of junction reliefs in the form of fabricated components. qués separately, applied to the main body of each element which forms its box structure and which presents the cavities for the embedding of the reliefs of junction of a similar element.

Grâce à l'application de cette idée, chaque groupe de reliefs de jonction forme une pièce de dimensions réduites sur laquelle les inégalités de contraction du matériel dont elle est formée n'ont pas une grande importance et, en outre, des précautions connues dans la technique d'estampage de petites pièces permettent de réduire cette inégalité de contraction à des limites négligeables. Il s'ensuit qu'il est possible de réaliser des éléments d'importantes dimensions d'ensembles, dans lesquels, cependant, les reliefs de jonction, qui forment la partie la plus délicate des éléments, ne sont pas défavorablement influencés par les grandes dimensions d'ensemble des éléments. Celà rend ainsi possible de respecter des tolérances appropriées dans l'interférence entre les organes de jonction, qui assurent des jonctions stables, de composition et dénouement faciles, sans recourir à la déformabilité élastique des parois, qui n'est pas disponible dans les éléments à boite fermée.Thanks to the application of this idea, each group of junctional reliefs forms a piece of reduced dimensions on which the contraction inequalities of the material from which it is formed are not of great importance and, moreover, precautions known in the art. small parts stamping technique can reduce this contraction inequality to negligible limits. It follows that it is possible to produce elements of large assembly dimensions, in which, however, the junction reliefs, which form the most delicate part of the elements, are not adversely affected by the large dimensions. of all the elements. This thus makes it possible to respect appropriate tolerances in the interference between the junction members, which ensure stable junctions, of easy composition and unwinding, without resorting to the elastic deformability of the walls, which is not available in the elements to be closed box.

Un autre développement de l'idée de l'invention consiste dans la réalisation des groupes de reliefs avec un matériel différent de celui qui forme les corps principaux des éléments.Another development of the idea of the invention consists in the realization of the relief groups with a material different from that which forms the main bodies of the elements.

Ainsi, d'une part, on peut utiliser de la meilleure façon l'idée de l'invention, en employant pour les groupes de reliefs un matériel moins sujet aux inégalités de contraction et, d'autre part, on peut choisir opportunément les deux matériaux de manière qu'il ne se vérifient pas de grippages et usures dans l'encastrement réciproque. Cela peut être fait même en adoptant pour les groupes de reliefs un matériel de prix relativement élevé, sans causer aucune grave influence sur le prix d'ensemble des éléments, étant donnée la petite masse des composants formés par les groupes de reliefs. Per exemple, dans une forme de réalisation préférée de l'invention, le corps principal des éléments est réalisé en chlorure de polyvinyle, qui assure une production économique, la possibilité de colorer d'une manière adéquate les éléments et d'obtenir une agréable présentation de ces éléments, et les groupes de reliefs sont réalisés en résine polyamide, laquelle est susceptible d'un estampage de précision et a des caractéristiques de résistance à l'usure et de auto-lubrification telles à assurer d'obtenir des jonctions à encastrement qui sont en même temps stables e glissantes. Alternativement, le corps principal des éléments peut être avantageusement réalisé, par exemple, en résine acry- lonitril-butadiène-styrène.Thus, on the one hand, the idea of the invention can be used in the best way, by using for the relief groups a material less subject to the inequalities of contraction and, on the other hand, one can conveniently choose the two materials in such a way that there is no evidence of seizures and wear in the reciprocal embedding. This can be done even by adopting a relatively high price material for the relief groups, without causing any serious influence on the overall price of the elements, given the small mass of the components formed by the relief groups. For example, in a preferred embodiment of the invention, the main body of the elements is made of polyvinyl chloride, which ensures economical production, the possibility of adequately coloring the elements and obtaining a pleasant presentation. of these elements, and the groups of reliefs are made of polyamide resin, which is capable of precision stamping and has characteristics of wear resistance and self-lubrication such as to ensure obtaining built-in junctions which are at the same time stable and slippery. Alternatively, the main body of the elements can advantageously be made, for example, of acrylonitrile-butadiene-styrene resin.

Un autre développement de l'idée de l'invention consiste dans l'application des groupes de reliefs de jonction aux corps principaux des éléments avec une mobilité limitée, selon la direction de plus grande extension des éléments.Another development of the idea of the invention consists in the application of groups of reliefs of junction to the main bodies of the elements with limited mobility, according to the direction of greatest extension of the elements.

Grâce à cette caractéristique, chaque groupe de reliefs de jonction peut se centrer automatiquement, au moment où l'on effectue l'encastrement, dans la respective cavité, en compensant ainsi même les imprécisions de position des mêmes cavités, qui sont dues, entre autre, aux inégalités de contraction du matériel qui constitue les corps principaux des éléments.Thanks to this characteristic, each group of junction reliefs can be centered automatically, at the time when the embedding is carried out, in the respective cavity, thus compensating even for the inaccuracies of position of the same cavities, which are due, inter alia , to the inequalities of contraction of the material which constitutes the main bodies of the elements.

A son tour, le corps principal de chaque élément est préférablement constitué par deux parties, une plus grande, comprenant la face supériemre de l'élément avec la cavité de jonction et les parois latérales, et l'autre plus petite, formant un culot de fermeture de la face inférieure du corps de l'élément et présentant des moyens pour recevoir l'application des groupes de reliefs de jonction. Ces deux parties du corps peuvent être rendues solidales au moyen de collage ou de soudure, particulièrement par soudure aux ultra-sons, tandis que l'application des groupes de reliefs de jonction au culot peut être préférablement effectuée au moyen de languettes à déclenchement élastique insérées dans des fentes. En orientant ces languettes et fentes selon la plus grande dimension de l'élément et en prévoyant un jeu approprié, il est ainsi très facile de réaliser la mobilité limitée qu'on désire pour les groupes de reliefs.In turn, the main body of each element is preferably constituted by two parts, a larger one, comprising the upper face of the element with the junction cavity and the side walls, and the other smaller, forming a base for closing the underside of the body of the element and having means for receiving the application of groups of junction reliefs. These two parts of the body can be made integral by means of gluing or welding, particularly by ultrasonic welding, while the application of the groups of relief junction to the base can preferably be carried out by means of elastic release tabs inserted. in slots. By orienting these tabs and slots according to the largest dimension of the element and by providing an appropriate clearance, it is thus very easy to achieve the limited mobility that is desired for the relief groups.

L'invention sera ulteriourement expliquée avec référence à une forme de réalisation constituant un exemple non limitatif, schématiquement représentée par le dessin joint dans lequel:The invention will be explained later with reference to an embodiment constituting a nonlimiting example, schematically represented by the attached drawing in which:

Les figures 1, 2 et 3 représentent un élément pour construction selon l'invention, formé par deux modules côte à côte, respectivement vu en élévation latérale, en plan et du bas;

  • les figures 4 et 5 en illustrent deux sections,respectivement faites selon les lignes IV-IV et V-V de la figure 3;
  • les figures 6, 7 et 8 représentent, isolé et interrompu, le culot de fermeture du corps de l'élément, respectivement vu de l'extérieur, en section selon la ligne VII-VII de la figure 6 et de l'intérieur;
  • la figure 9 illustre un groupe de goujons de connexion, vu de l'intérieur.
Figures 1, 2 and 3 show an element for construction according to the invention, formed by two modules side by side, respectively seen in side elevation, in plan and bottom;
  • Figures 4 and 5 illustrate two sections, respectively made along lines IV-IV and VV of Figure 3;
  • Figures 6, 7 and 8 show, isolated and interrupted, the closure base of the body of the element, respectively seen from the outside, in section along line VII-VII of Figure 6 and from the inside;
  • Figure 9 illustrates a group of connecting studs, viewed from the inside.

L'élément représenté est en forme d'un parallélépipède rectangulaire et, dans cet exemple, il a une hauteur égale à la largeur et une longueur double des deux premières; l'élément correspond, donc, à deux éléments unitaires ou modules, cubiques dans ce cas, disposés côte à côte.The element represented is in the form of a rectangular parallelepiped and, in this example, it has a height equal to the width and a length double of the first two; the element therefore corresponds to two unit elements or modules, cubic in this case, arranged side by side.

Le corps de l'élément comprend une première partie à coque formée par la face supérieure 1, des faces latérales 2 et des faces d'extrémité 3. Dans la face supérieure 1 sont formées deux cavités 4 de section circulaire, destinées à recevoir l'encastrement des reliefs de jonction d'un autre élément analogue. La paroi périmétrale de chaque cavité 4 présente, dans ce cas, des nervures verticales 5 destinées à établir, entre les divers élémentB,des positions de jonction opportunément orientées.The body of the element comprises a first shell part formed by the upper face 1, lateral faces 2 and end faces 3. In the upper face 1 are formed two cavities 4 of circular section, intended to receive the embedding the reliefs of junction of another similar element. The perimeter wall of each cavity 4 has, in this case, vertical ribs 5 intended to establish, between the various elementB, conveniently oriented junction positions.

La face inférieure de la coque 1 - 5 est fermée par un culot 6 inséré en un siège des bords des parois latérales 2 et d'extrémité 3, et il y est fixé, par exemple, au moyen de soudure à ultra-sons. Le culot 6 présente, sur le même axe de la cavité 4 de la paroi supérieure 1, des cavités 7 qui, dans ce cas, sont elles aussi circulaires. Lelong de deux parties diamétralement opposées de la périphérie des cavités 7, s'extendent deux fentes 8 qui sont orientées avec leur plus grande dimension substantiellement paralléle à la plus grande dimension (longueur) de l'élément pour construction. Les parties 1- 3 et 6 peuvent être fabriquées, par exemple, en chlorure de polyvinyle.The underside of the shell 1 - 5 is closed by a base 6 inserted in a seat at the edges of the side walls 2 and end 3, and it is fixed there, for example, by means of ultrasonic welding. The base 6 has, on the same axis of the cavity 4 of the upper wall 1, cavities 7 which, in this case, are also circular. Along two diametrically opposite parts of the periphery of the cavities 7, extend two slots 8 which are oriented with their largest dimension substantially parallel to the largest dimension (length) of the building element. Parts 1-3 and 6 can be made, for example, of polyvinyl chloride.

Séparément des parties décrite jusqu'ici, on fabrique una plaquette 9, dans ce cas circulaire et de diamètre légèrement inférieur à celui de la cavité 7 du culot 6, dont l'épaisseur correspond substantiellement à la profondeur desdites cavités 7. Du côté extérieur de la plaquette 9 s'extendent quatre goujons de jonction 10 disposés de manière qu'ils puissent s'introduire, avec accouplement légèrement forcé, dans une cavité 4 de la paroi supérieure 1 du corps d'un élément pour construction. Dans ce cas, les quatre goujons 10 sont cylindriques et disposés comme les sommets d'un carré. Du côté intérieur de la plaquette 9 s'étendent deux languettes 11 diamétralement opposées qui se terminent à dent et sont disposées de manière qu'elles puissent s'introduire avec un peu de jeu dans les fentes 8 du culot 6 et s'y engager par déclenchement élastique.Separately from the parts described so far, a wafer 9 is produced, in this case circular and of slightly smaller diameter than that of the cavity 7 of the base 6, the thickness of which corresponds substantially to the depth of said cavities 7. On the outside of the plate 9 extend four connecting studs 10 arranged so that they can be inserted, with slightly forced coupling, into a cavity 4 of the upper wall 1 of the body of a building element. In this case, the four studs 10 are cylindrical and arranged like the vertices of a square. On the inner side of the plate 9 extend two diametrically opposite tongues 11 which end with teeth and are arranged so that they can be inserted with a little play in the slots 8 of the base 6 and engage therein by elastic release.

En conséquence,quand on a préparé le corps de l'elément pour construction en appliquant le culot 6-8 au corps 1-5, on complète l'élément en introduisant, à déclenchement élastique,une plaquette 9 dans chaque cavité 7 du culot 6 (dans le cas de l'élément représenté on introduit donc deux plaquettes 9) de manière que les plaquettes 9 occupent substantiellement les cavités7, les dents des languettes 11 déclanchent derrière le culot 6 en fixant les plaquettes (figure 5), et de la face de l'élément qui est opposée à la face 1 qui présente les cavités4, les goujons de jonction 10 sont saillants (figures 1, 3 et 4) et disposés pour s'introduire dans la cavité 4 d'un élément analogue, et effectuer ainsi la jonction à encastrement des deux éléments.Consequently, when the body of the element for construction has been prepared by applying the base 6-8 to the body 1-5, the element is completed by introducing, with elastic release, a plate 9 in each cavity 7 of the base 6 (in the case of the element shown, two inserts 9 are therefore introduced) so that the inserts 9 substantially occupy the cavities 7, the teeth of the tongues 11 release behind the base 6 by fixing the inserts (FIG. 5), and from the face of the element which is opposite to the face 1 which has the cavities 4, the connecting studs 10 are protruding (FIGS. 1, 3 and 4) and arranged to be introduced into the cavity 4 of a similar element, and thus effect the interlocking junction of the two elements.

Dans ce cas, les plaquettes 9 sont appliquées aux culots 6 de manière que les carrés idéals définis par les goujons 10 sont inclinés de 45° par rapport aux côtes des culots, ce qui assure une plus grande stabilité. En outre, l'espace entre les quatre goujons 10 de chaque groupe correspond aux dimensions d'un goujon et cela permet, si on le veut, d'unir deux éléments par jonction de goujons contre goujons, de manière analogue à la réalisation de la disposition selon le brevet italien No. 739.869.In this case, the plates 9 are applied to the caps 6 so that the ideal squares defined by the studs 10 are inclined by 45 ° relative to the ribs of the caps, which ensures greater stability. In addition, the space between the four studs 10 of each group corresponds to the dimensions of a stud and this allows, if desired, to join two elements by joining studs against studs, in a similar manner to the embodiment of the arrangement according to the Italian Patent No. 739,869.

Le composant 9, 10, 11 est relativement petit,indépendamment des dimensions d'un élément de costruction (qui peut correspondre même à plusieurs éléments unitaires ou modules). Il peut être fabriqué, par exemple, en résine de polyamide, assurant d'excellentes qualités de jonction par rapport aux cavités 4 du corps de l'élément, qui est fait, dans cet exemple, en chlorure de polyvinyle. En outre, le jeu qui existe entre la périphérie de la plaquette 9 et le siège creux 7, ainsi qu'entre les languettes 11 et les fentes 8 (dans la direction de la plus grande extension de ces dernières) accorde une légère mobilité aux groupes de goujons de jonction 10 par rapport au corps de l'élément et, de conséquence, leur exacte adaptation aux positions, éventuellement peu précises comme construction ou à cause de contractions inégales d'un élément accouplé.Component 9, 10, 11 is relatively small, independently of the dimensions of a construction element (which can even correspond to several unit elements or modules). It can be made, for example, of polyamide resin, ensuring excellent joining qualities with respect to the cavities 4 of the body of the element, which is made, in this example, of polyvinyl chloride. In addition, the play which exists between the periphery of the plate 9 and the hollow seat 7, as well as between the tongues 11 and the slots 8 (in the direction of the greatest extension of the latter) grants slight mobility to the groups. of connecting studs 10 relative to the body of the element and, consequently, their exact adaptation to the positions, possibly imprecise as construction or because of unequal contractions of a coupled element.

Naturellement, l'élément pour construction selon l'invention présente les cavités 4 seulement s'il est destiné à être un élément intermédiaire et à recevoir des jonctions des deux côtés; il peut en être dépourvu quand il doit être simplement accouplé à un autre élément moyennant ses propres goujons 10. Dans ce cas, la forme de son corps peut être complètement arbitraire. En tout cas, les dimensions et la forme de l'élément peuvent aussi varier, mais préférablement par multiples d'un élément unitaire idéal ou module, non nécessairement cubique. Les reliefs de jonction 10 des plaquettes 9 peuvent avoir une forme différente de celle des goujons, et même le nombre des reliefs d'un groupe peut être différent de quatre; la forme des cavités4 peut ne pas être circulaire pourvu qu'elle soit convenable à la forme et disposition des reliefs de jonction. L'emploi de différentes matières pour les corps des éléments et pour lesgroupes de reliefs de jonction peut, dans certains cas, ne pas être nécessaire. Même la mobilité des plaquettes 9 peut dans certains cas ne pas être demandée, tel qu'il se vérifie, par exemple, pour les éléments unimodulaires. Dans ces cas lesdits jeux peuvent manquer, ou bien il peuvent être présents seulement pour maintenir l'uniformité de fabrication des divers éléments de la construction. Les cavités 7 des culots 6 pourraient ne pas être circulaires mais ovalisées, pour présenter, par rapport aux plaquettes 9, un jeu dans la seule direction de leur mobilité; le même effet pourrait être obtenu en ovalisant, au contraire, les plaquettes 9. Le corps de l'élément pour construction pourrait résulter de trois pièces, une périmétrale et deux culots, ou bien les fonctions décrites pour la paroi supérieure 1 et pour le culot 6 pourraient être échangées.Naturally, the building element according to the invention has the cavities 4 only if it is intended to be an intermediate element and to receive junctions on both sides; it can be devoid of it when it has to be simply coupled to another element by means of its own studs 10. In this case, the shape of its body can be completely arbitrary. In any case, the dimensions and the shape of the element can also vary, but preferably by multiples of an ideal unit element or module, not necessarily cubic. The junction reliefs 10 of the plates 9 can have a shape different from that of the studs, and even the number of reliefs of a group can be different from four; the shape of the cavities4 may not be circular provided that it is suitable for the shape and arrangement of the junction reliefs. The use of different materials for the bodies of the elements and for the groups of junction reliefs may, in some cases, not be necessary. Even the mobility of the plates 9 may in some cases not be requested, as is verified, for example, for the unimodular elements. In these cases, the said clearances may be missing, or else they may be present only to maintain the uniformity of manufacture of the various elements of the construction. The cavities 7 of the caps 6 could not be circular but ovalized, to present, with respect to the plates 9, a clearance in the only direction of their mobility; the same effect could be obtained by ovalizing, on the contrary, the plates 9. The body of the element for construction could result from three parts, a perimeter and two caps, or else the functions described for the upper wall 1 and for the cap 6 could be exchanged.
