20 distance entre les centres de ces parties sphériques étant sensiblement égale au diamètre de celles-ci. L'élément récepteur peut être formé par un chaînon simple ou multiple qui présente à ses deux extrémités opposées des logements destinés à recevoir 5 des parties sphériques telles que mentionnées plus haut. Le logement précité peut être limité également à au moins un de ses côtés par une lèvre articulée élastiquement qui enserre la partie sphérique de l'organe d'accouplement qui se trouve dans le logement. 0 D'autres avantages et particularités de l'invention apparaîtront dans la description donnée ci-après de quelques formes d'exécution spécifiques des éléments de construction conformes à l'invention. La figure 1 est une forme d'exécution d'un élément pénétrant;20 distance between the centers of these spherical parts being substantially equal to the diameter thereof. The receiving element can be formed by a single or multiple link which has at its two opposite ends housings intended to receive spherical parts as mentioned above. The aforementioned housing can also be limited to at least one of its sides by an elastically articulated lip which encloses the spherical part of the coupling member which is located in the housing. 0 Other advantages and features of the invention will appear in the description given below of some specific embodiments of the construction elements according to the invention. Figure 1 is an embodiment of a penetrating element;
Les figures 2 et 3 sont des représentations en perspective des formes particulières des éléments pénétrants;Figures 2 and 3 are perspective representations of the particular shapes of the penetrating elements;
Les figures 4, 5 et -6 représentent respective¬ ment en perspective un élément récepteur, un élément pénétrant modifié et leur assemblage, la figure 6 comportant un arrachement partiel. Les figures 7, 8 et 9 sont une représentation graphique des dimensions relatives des éléments suivant les figures 4, 5 et 6.Figures 4, 5 and -6 represent respective¬ ment in perspective a receiving element, a modified penetrating element and their assembly, Figure 6 having a partial cutaway. Figures 7, 8 and 9 are a graphic representation of the relative dimensions of the elements according to Figures 4, 5 and 6.
La figure 10 est une vue partielle de profil de deux éléments récepteurs liés par un élément pénétrant et la figure 11 est une vue latérale correspon¬ dante.FIG. 10 is a partial profile view of two receiving elements linked by a penetrating element and FIG. 11 is a corresponding side view.
La figure 12 est une variante d'exécution. Dans les diverses figures, les mêmes repères de référence désignent des éléments identiques ou analogues .Figure 12 is an alternative embodiment. In the various figures, the same reference marks designate identical or analogous elements.
L'élément pénétrant 2 représenté à la figure 1 est munie de deux parties sphériques 7, qui sont solidaires entre elles au moyen d'une pièce intermé¬ diaire 17 cylindrique, de sorte qu'entre ces parties 7 on ait formé un rétrécissement annulaire. La distance "a" entre les centres de ces parties sphériques est à peu près égale au diamètre de celles-ci.The penetrating element 2 shown in Figure 1 is provided with two spherical parts 7, which are integral with each other by means of a cylindrical intermé¬ part 17, so that between these parts 7 has been formed an annular narrowing. The distance "a" between the centers of these spherical parts is approximately equal to the diameter of these.
Dans la figure 3, on a représenté trois parties sphériques solidarisées par des pièces intermédiaires 17, tandis que dans la figure 3, on a représenté un élément pénétrant 2 constitué par un boîtier cubique 19 sur lequel par exemple deux parties sphériques sont fixées d'équerre l'une par rapport à l'autre, tandis que dans les deux extrémités ouvertes du boîtier, en peut monter deux parties sphériques 7 de manière amovible au moyen d'un embout 20 qui peut être glissé dans ce boîtier 19. BUREAIn Figure 3, there are shown three spherical parts secured by intermediate parts 17, while in Figure 3, there is shown a penetrating element 2 consisting of a cubic housing 19 on which for example two spherical parts are fixed square one relative to the other, while in the two open ends of the housing, two spherical parts 7 can be mounted therefrom in a removable manner by means of an end piece 20 which can be slid into this housing 19. B UREA
OMPI Cet embout présente, sur ses faces latérales, des encoches 21 qui coopèrent avec des nervures corres¬ pondantes 22 qui sont ménagées dans les parois inté¬ rieures du boîtier et qui permettent donc de retenir l'embout suffisamment fermement dans le boîtier et ce d'une manière amovible.WIPO This end piece has, on its lateral faces, notches 21 which cooperate with corres¬ laying ribs 22 which are formed in the interior walls of the housing and which therefore make it possible to retain the endpiece sufficiently firmly in the housing and this a removable way.
L'épaisseur de l'embout 20 est au maximum égale à la moitié de la hauteur du boîtier 19, de sorte que l'on peut y fixer en même temps une partie sphérique 7 dans les deux extrémités.The thickness of the end piece 20 is at most equal to half the height of the housing 19, so that a spherical part 7 can be fixed therein at both ends.
On peut donc, sur cet élément particulier, construire dans des directions différentes situées d'équerre l'une par rapport à l'autre.We can therefore, on this particular element, build in different directions located at right angles to each other.
La figure 2 représente un autre élément pénétrant particulier 2 qui consiste en trois parties sphériques 7 qui se suivent dans la même direction et qui sont sépa¬ rées les unes des autres par des rétrécissements 17.FIG. 2 shows another particular penetrating element 2 which consists of three spherical parts 7 which follow each other in the same direction and which are separated from one another by narrowing 17.
Dans la forme d'exécution des figures 4, 5 et 6 un élément récepteur 1 est formé par un chaînon qui comporte à ses deux extrémités opposées des logements 5 pour les parties sphériques 7 d'un élément pénétrant 2.In the embodiment of FIGS. 4, 5 and 6 a receiving element 1 is formed by a link which has at its two opposite ends housings 5 for the spherical parts 7 of a penetrating element 2.
Ce chaînon 1 consiste en deux parties en forme de H,9 et 10, parallèles entre elles, et espacées l'une de l'autre d'une distance qui est un peu inférieure au diamètre d'une partie sphérique 7, de sorte que cette dernière puisse être bloquée entre les branches 11 et 12 de ces deux parties en forme de H, 9 et 10.This link 1 consists of two H-shaped parts, 9 and 10, parallel to each other, and spaced from each other by a distance which is a little less than the diameter of a spherical part 7, so that the latter can be blocked between the branches 11 and 12 of these two H-shaped parts, 9 and 10.
A cet effet, les branches 11 et 12 de la partie en forme de H, 9, sont reliées élastiquement avec les branches correspondantes 11 et 12 de la partie en forme de H, 10 qui leur sont opposées pour former les logements 5 des parties sphériques 7.For this purpose, the branches 11 and 12 of the H-shaped part, 9, are elastically connected with the corresponding branches 11 and 12 of the H-shaped part, 10 which are opposite to them to form the housings 5 of the spherical parts. 7.
Dans la forme d'exécution suivant les figures 4 et 6, seules les extrémités libres des branches 11 et des branches 12 des deux parties en forme de H, 9 et 10, sont reliées deux à deux par des pièces intermé¬ diaires cintrées 13 qui sont situées dans le plan des branches correspondantes .In the embodiment according to FIGS. 4 and 6, only the free ends of the branches 11 and of the branches 12 of the two H-shaped parts, 9 and 10, are connected two by two by curved intermediate parts 13 which are located in the plane of the corresponding branches.
Pour faciliter la pénétration des éléments pénétrants 2, des encoches 6 peuvent être prévues dans les branches cintrées 13, comme représenté aux figures 4 et 6.To facilitate the penetration of the penetrating elements 2, notches 6 can be provided in the curved branches 13, as shown in FIGS. 4 and 6.
On notera également que les surfaces délimitées respectivement par les branches 11 et les parties cintrées 13 supérieures d'une part et par les branches 12 et les parties cintrées 13 inférieures d'autre part peuvent être pleines et servir de 'support publicitaire ou autre.It will also be noted that the surfaces delimited respectively by the branches 11 and the upper curved parts 13 on the one hand and by the branches 12 and the lower curved parts 13 on the other hand can be full and serve as advertising or other support.
Avantageusement quelques unes au moins des parties sphériques 7 sont pourvues d'organes de verrouillage qui permettent de limiter le mouvement de rotation de la partie sphérique intéressée dans un logement 5 de l'élément récepteur.Advantageously, at least some of the spherical parts 7 are provided with locking members which make it possible to limit the rotational movement of the spherical part concerned in a housing 5 of the receiving element.
Dans la forme d'exécution suivant les figures 5 et 6, un organe de verrouillage de ce type est formé par un epaulement circulaire 14 dont le centre est situé sur un axe perpendiculaire à celui sur lequel se trouvent les centres des deux parties sphériques 7 de l'élément pénétrant 2. La hauteur de l'epaulement 14 est, au plus, limitée par le plan tangent à la partie sphérique 7, au centre de cet epaulement; celui-ci peut donc éven¬ tuellement se trouver plus bas.In the embodiment according to FIGS. 5 and 6, a locking member of this type is formed by a circular shoulder 14 whose center is located on an axis perpendicular to that on which the centers of the two spherical parts 7 of the penetrating element 2. The height of the shoulder 14 is, at most, limited by the plane tangent to the spherical part 7, at the center of this shoulder; it can therefore possibly be lower.
En outre, l'élément pénétrant selon les figures 5 et 6 présente une cavité cylindrique 15 dont l'axe est situé sur l'axe qui relie les centres des deux parties sphériques, cette cavité débouchant par ses deux extrémités à la surface extérieure de ces parties sphériques 7. Dans certaines formes d'exécution, le centre de cet epaulement peut être situé sur le même axe que celui qui relie les centres des deux parties sphériques .In addition, the penetrating element according to FIGS. 5 and 6 has a cylindrical cavity 15 whose axis is located on the axis which connects the centers of the two spherical parts, this cavity opening by its two ends to the external surface of these spherical parts 7. In certain embodiments, the center of this shoulder may be located on the same axis as one that connects the centers of the two spherical parts.
_Dans d'autres cas, on peut prévoir sur une même partie sphérique 7 des épaulements diamétralement opposés l'un à l'autre. Dans d'autres cas encore, on peut prévoir seulement un epaulement sur l'une des parties sphériques_In other cases, it is possible to provide on the same spherical part 7 shoulders diametrically opposite one another. In still other cases, it is possible to provide only a shoulder on one of the spherical parts.
Les centres des divers épaulements peuvent aussi être situés sur un même plan axial de l'élément pénétrant ou bien les centres des épaulements de l'une des parties sphériques peuvent se trouver dans un plan perpendiculaire au plan qui contient les centres des épaulements de l'autre partie sphérique.The centers of the various shoulders can also be located on the same axial plane of the penetrating element or else the centers of the shoulders of one of the spherical parts can be in a plane perpendicular to the plane which contains the centers of the shoulders of the other spherical part.
Dans la forme d'exécution suivant les figures 5 et 6, on a prévu sur chacune des parties sphériques deux épaulements dont les centres sont diamétralement opposés l'un à l'autre et sont situés dans un même plan axial.In the embodiment according to Figures 5 and 6, there are provided on each of the spherical parts two shoulders whose centers are diametrically opposite one another and are located in the same axial plane.
Le mouvement de rotation de l'élément pénétrant 2 par rapport à l'élément récepteur 1 est limité en fonction de la position de l'organe de verrouillage, plus spécifiquement de l'epaulement 14, sur la partie sphérique.The rotational movement of the penetrating element 2 relative to the receiving element 1 is limited as a function of the position of the locking member, more specifically of the shoulder 14, on the spherical part.
Ainsi par exemple, suivant la figure 6, l'élément pénétrant 2 ne peut subir une rotation que sur un seul axe parallèle aux eTitretoises 16 des parties en forme de H, 9 et 10. Si le centre de l'epaulement est situé sur l'axe qui relie les centres des parties sphériques, c'est-à-dire sur le même axe que la cavité 15, l'élément pénétrant 2 ne peut alors tourner qu'autour de l'axe de cette cavité cylindrique.Thus, for example, according to FIG. 6, the penetrating element 2 can only be rotated on a single axis parallel to the eTitretoises 16 of the H-shaped parts, 9 and 10. If the center of the shoulder is located on the 'axis which connects the centers of the spherical parts, that is to say on the same axis as the cavity 15, the penetrating element 2 can then rotate only around the axis of this cylindrical cavity.
Il est évident que ce qui vient d'être dit à propos des épaulements est applicable à toutes les formes d'exécution de l'élément pénétrant, notamment aux exécutions montrées aux figures 2, 3 et 5. Afin de réduire au minimum le jeu entre les divers éléments de construction reliés entre eux et d'obtenir ainsi un enchaînement précis de ces éléments, et ce avec un maximum de possibilités de combinaison, il est important que les dimensions relatives des éléments récepteurs et des éléments pénétrants répondent à des conditions déterminées.It is obvious that what has just been said about the shoulders is applicable to all embodiments of the penetrating element, in particular to the embodiments shown in FIGS. 2, 3 and 5. In order to minimize the play between the various building elements linked together and to obtain a precise sequence of these elements, and this with a maximum of combination possibilities, it is important that the relative dimensions of the receiving elements and penetrating elements meet certain conditions.
Ces dimensions sont présentées graphiquement aux figures 7, 8 et 9.These dimensions are presented graphically in Figures 7, 8 and 9.
Ainsi, il est important que la distance exté¬ rieure a entre les parties en forme de H soit à peu près égale au diamètre des parties sphériques 7 et que la dis¬ tance intérieure b entre celles-ci soit à peu près égale à celle du rétrécissement 17 entre les deux parties sphériques 7 consécutives. De plus,, la largeur des parties en forme de H est à peu près égale au diamètre des parties sphériques 7 et constitue deux logements 5 opposés l'un à l'autre pour recevoir les parties sphéri¬ ques, l'exécution des parties en forme de H étant telle que les centres des parties sphériques se trouvent dans _ ces logements espacés l'un de l'autre d'une distance égale à leur diamètre.Thus, it is important that the external distance a between the H-shaped parts is approximately equal to the diameter of the spherical parts 7 and that the internal distance b between them is approximately equal to that of narrowing 17 between the two consecutive spherical parts 7. In addition, the width of the H-shaped parts is approximately equal to the diameter of the spherical parts 7 and constitutes two housings 5 opposite one another to receive the spherical parts, the execution of the parts in H shape being such that the centers of the spherical parts are in _ these housings spaced from each other by a distance equal to their diameter.
La distance intérieure b entre les branches d'une même partie en forme de H est également à peu près égale au diamètre du rétrécissement 17.The internal distance b between the branches of the same H-shaped part is also approximately equal to the diameter of the constriction 17.
L'espace 18 entre 1*entretoise 16 et la base des branches qui se raccordent d'un côté à cette dernière a la forme d'un demi-cercle dont le rayon correspond approximativement à celui de 1'epaulement circulaire 14. Le centre 0 de ce demi-cercle est situé dans le plan de symétrie longitudinal S, des parties en forme de H, 9 et 10, perpendiculairement à l'entre- toise 16 et à une distance du milieu de celle-ci à peu près égale au rayon des parties sphériques.The space 18 between the spacer 16 and the base of the branches which are connected on one side to the latter has the shape of a semicircle whose radius corresponds approximately to that of the circular shoulder 14. The center 0 of this semicircle is located in the longitudinal plane of symmetry S, H-shaped parts, 9 and 10, perpendicular to the spacer 16 and at a distance from the middle thereof roughly equal to the radius spherical parts.
Lesdites pièces intermédiaires cintrées 13 ont également à peu près la forme d'un demi-cercle dont le rayon est approximativement égal à celui de 1'epaulement circulaire 14 et dont le centre 0* est situé au milieu entre les deux parties en forme de H,Said curved intermediate pieces 13 also have roughly the shape of a semicircle whose radius is approximately equal to that of the circular shoulder 14 and whose center 0 * is located in the middle between the two H-shaped parts,
9 et 10, à une distance du plan de symétrie transversal9 and 10, at a distance from the transverse plane of symmetry
S_ à peu près égale au rayon des parties sphériques .S_ roughly equal to the radius of the spherical parts.
Les centres 0 et O' se trouvent donc dans un même plan, parallèlement au plan de symétrie S-.The centers 0 and O 'are therefore in the same plane, parallel to the plane of symmetry S-.
La profondeur du rétrécissement 17 entre les parties sphériques 7 de l'élément pénétrant 2 répond approximativement à l'équation suivante : x = R (l - )The depth of the narrowing 17 between the spherical parts 7 of the penetrating element 2 corresponds approximately to the following equation: x = R (l -)
V"2 dans laquelle x est la profondeur du rétrécissement et R est le rayon des parties sphériques 7. Cette formule est illustrée graphiquement par la figure 7.V " 2 in which x is the depth of the narrowing and R is the radius of the spherical parts 7. This formula is illustrated graphically in FIG. 7.
Sur la base de cette formule, on peut déterminer toutes les dimensions, aussi bien de l'élément récepteur 1 suivant la figure 4 que de l'élément pénétrant 2 suivant la figure 5. Ainsi les branches 11 et 12 des parties en forme de H ont une section transversale carrée dont le côté est égal à x.On the basis of this formula, all the dimensions can be determined, both of the receiving element 1 according to FIG. 4 and of the penetrating element 2 according to FIG. 5. Thus the branches 11 and 12 of the H-shaped parts have a square cross section whose side is equal to x.
Dans lé cas de la figure 4, il est bien entendu que si une surépaisseur est prévue pour fermer par exemple la surface supérieure délimitée par la partie cintrée 13 et les branches 11, ies dimensions doivent tenir compte de cette surépaisseur.In the case of FIG. 4, it is understood that if an additional thickness is provided for closing, for example, the upper surface delimited by the curved part 13 and the branches 11, the dimensions must take account of this additional thickness.
Les logements 5 présentent une ouverture de pénétration pour les parties sphériques 7 dont la plus petite largeur, qui correspond à la distance intérieure entre les pièces intermédiaires 13, est égale au diamètre des parties sphériques diminué de deux fois la profondeur x du rétrécissement 17 mentionné.The housings 5 have a penetration opening for the spherical parts 7, the smallest width of which corresponds to the interior distance between the intermediate parts 13, is equal to the diameter of the spherical parts reduced by twice the depth x of the narrowing 17 mentioned.
Ce qui précède, en référence aux figures 4 à 9, s'applique mutatis utandis aux formes d'exécution des figures 2 et 3 qui concernent des éléments pénétrants 7 servant à former des liaisons en T ou angulaires avec des éléments récepteurs 1 (non représentés) .The above, with reference to FIGS. 4 to 9, applies mutatis utandis to the embodiments of FIGS. 2 and 3 which relate to penetrating elements 7 used to form T or angular connections with receiving elements 1 (not shown ).
Il va de soi qu'il est possible de prévoir encore d'autres formes d'éléments pénétrants ou d'éléments récepteurs . Ainsi, par exemple, les chaînons peuvent être simples, comme a la figure 4, ou être multiples. Dans le cas de chaînons multiples, ceux-ci peuvent par exemple consister en deux ou plusieurs chaînons simples joints l'un à l'autre.It goes without saying that it is possible to provide still other forms of penetrating elements or receiving elements. Thus, for example, the links can be simple, as in Figure 4, or be multiple. In the case of multiple links, these may for example consist of two or more single links joined to one another.
Les éléments chaînons 1 de la- figure 4 peuvent être assemblés en une chaîne ouverte ou fermée ou en une construction ramifiée en réunissant alternativement un élément pénétrant et un élément récepteur qui sont reliés entr'eux.The link elements 1 of FIG. 4 can be assembled in an open or closed chain or in a branched construction by alternately joining together a penetrating element and a receiving element which are connected together.
Suivant la nature et la place relative dans les logements 5 des parties sphériques 7, on peut obtenir un ensemble complètement rigide, un ensemble partiellement rigideou un ensemble totalement souple et limiter les déplacements angulaires relatifs et la position relative de l'epaulement circulaire 14 par rapport au logement 5.Depending on the nature and the relative place in the housings 5 of the spherical parts 7, it is possible to obtain a completely rigid assembly, a partially rigid assembly or a completely flexible assembly and to limit the relative angular displacements and the relative position of the circular shoulder 14 with respect to to accommodation 5.
Pour raccorder deux prismes l'un à l'autre, il suffit de presser une partie sphérique, par exemple 7, de l'élément pénétrant 2 dans le logement 5 désiré d'un prisme 1 et de presser 1'autre partie sphérique 7 du même élément pénétrant 2 dans le logement 5 désiré de l'autre prisme ll (figures 10 et 11).To connect two prisms to each other, it suffices to press a spherical part, for example 7, of the penetrating element 2 into the desired housing 5 of a prism 1 and to press the other spherical part 7 of the same penetrating element 2 in the desired housing 5 of the other prism l l (Figures 10 and 11).
Les logements 5 forment un rétrécissement 8 à peu près à la surface du prisme dans laquelle ils débouchent et une lèvre 29 mobile élastiquement limite au moins un des côtés du logement de manière telle que cette lèvre 29 serre les parties sphériques 7 de l'élément 2 qui se trouvent dans les logements 5. Par conséquent, si les prismes 1 et 1* et les éléments pénétrants 2 sont fabriqués en une matière thermoplastique usuelle, comme le polyéthylène, la lèvre 29 présente une élasticité suffisante pour permettre de presser une partie sphérique 7 dans le logement correspondant et de maintenir celle-ci en place et ledit élément pénétrant 2 peut être deThe housings 5 form a narrowing 8 approximately on the surface of the prism into which they open and a lip 29 movable elastically limits at least one of the sides of the housing so that this lip 29 grips the spherical parts 7 of the element 2 which are located in the housings 5. Consequently, if the prisms 1 and 1 * and the penetrating elements 2 are made of a usual thermoplastic material, such as polyethylene, the lip 29 has sufficient elasticity to allow a spherical part to be pressed 7 in the corresponding housing and to keep it in place and said penetrating element 2 can be
"BUREAT nouveau retiré de son logement par un mouvement de traction simple."OFFICE again removed from its housing by a simple pulling movement.
Si le logement ne se trouve pas à proximité d'un coin du prisme, comme par exemple le logement 5' à la figure 10, on prévoit du côté de la lèvre 9 opposé à celui-ci un évidement 30 dans lequel on peut glisser une pièce de tension.If the housing is not located near a corner of the prism, such as for example the housing 5 ′ in FIG. 10, there is provided on the side of the lip 9 opposite to it a recess 30 in which one can slide a tension piece.
Ainsi que le montrent les figures ÎO et 11, les logements peuvent se trouver à proximité d'une arête du prisme; dans ce cas, ceux-ci sont ouverts sur deux au moins des surfaces du prisme qui limitent l'arête.As shown in FIGS. 10 and 11, the housings can be located near an edge of the prism; in this case, these are open to at least two of the surfaces of the prism which limit the edge.
Si, par exemple, le prisme est en forme de panneau, son épaisseur est à peu près égale au diamètre des parties sphéxiques 7, de sorte que les logements prévus dans le prisme pour ces organes d'accouplement peuvent déboucher en même temps sur les deux grandes surfaces opposées dudit prisme en forme de panneau.If, for example, the prism is in the form of a panel, its thickness is approximately equal to the diameter of the spherical parts 7, so that the housings provided in the prism for these coupling members can open at the same time on both large opposite surfaces of said panel-shaped prism.
Il convient de noter que de nombreuses variantes d'exécution de l'invention relevant du principe reven- diqué sont possibles. C'est ainsi qu'on peut concevoir un élément tel que représenté à la figure 12 qui com¬ porte à la fois une partie pénétrante 2 constituée par une partie sphérique 7 reliée en 17 à un élément récep¬ teur 1 comportant un seul logement 5. Des éléments de ce type peuvent être enchaînés en faisant pénétrer une partie sphérique 7 d'un premier élément dans le logement 5 d'un élément voisin (non représenté). Cette variante d'exécution est cependant plus difficile à exécuter par in ection de résines .It should be noted that many alternative embodiments of the invention falling within the claimed principle are possible. This is how we can design an element as shown in FIG. 12 which includes both a penetrating part 2 constituted by a spherical part 7 connected in 17 to a receiver element 1 comprising a single housing 5 Elements of this type can be linked by making a spherical part 7 of a first element penetrate into the housing 5 of a neighboring element (not shown). This variant of execution is however more difficult to execute by in ection of resins.
