Abstract

1. Joint for spatial framework structures in geometric module with pyramidal base and tetrahedral (fig.1) in which converge same shafts endowed with spheres at the tips directed in every direction in the space, it is composed of two parts jointed together by one central bolt, it is caracterized by two caps of changeable thickness, semispheric and hollow, in which converge twelve shafts (7) (fig. 3) endowed with one sphere (9) through one pipe (8), four horizontal and eight oblique, they are characterized by four large slits (4) orthogonal to each other, to allow the introduction of the spheric terminals of the oblique shafts, and characterized by four semicircular holes (5) to allow the introduction of spheric terminals of the four horizontal shafts, so that the central bolt (1) that cross the hole of the cap is tangent to the spheres of the shafts and at the same time all the spheres are tangent to the hemispheric inside surface of the two caps when these caps are assembled with the introduction of the terminal of the shafts in the slits (4) and (5), allowing their rotation in every direction in the space after the blockage.

Description

L'invention concerne un joint composé par des calottes hémisphériques les quelles,unies ensemble par un boulon central qui les traverse,renferment les bouts des hampes,douées de billes,de sorte qu'elles se bloquent.The invention relates to a joint composed of hemispherical caps which, united together by a central bolt which passes through them, enclose the ends of the stems, endowed with balls, so that they lock.

Les structures aux grillages spatiaux exploitent le critères de la répétition,de sorte que le module à la base,de n'importe quelle geometrie,se multiplie dans l'espace,en y ajoutant des hampes et des joints,de manière à engendrer des grandes structures.The structures with spatial grids exploit the criteria of repetition, so that the module at the base, of any geometry, multiplies in space, adding stems and joints, so as to generate large structures.

On connaît déjà un grand nombre de semblables systèmes qui sont composés par le même mécanisme (MERO allemand,UNISTRUT américain,etc.). Ils sont tous fondés sur le critère que le joint est,au point de vue statique,un incastrement: c'est à dire que toutes les hampes sont rigidement liées entre elles. Ce principe consent un nombre limité de géométries. Un autre inconvénient est que chaque hampe est individuellement vissé sur le joint: cela comporte des élevés temps de montage,très négatif pour ces systèmes souvent composée par milliers de hampes et de joints.A large number of similar systems are already known which are composed by the same mechanism (German MERO, American UNISTRUT, etc.). They are all based on the criterion that the joint is, from the static point of view, an embedding: that is to say that all the stems are rigidly linked together. This principle allows a limited number of geometries. Another drawback is that each pole is individually screwed onto the joint: this involves long assembly times, very negative for these systems often made up of thousands of poles and joints.

La présente invention a pour but de remédier à ces inconvénients.L'invention,tel qu'elle est caractérisée dans les revendications,résout le problème du joint-encastrement en realisant le joint-charnière.En effet,grâce à les billes concentriques, les hampes, même si bloqué, ont la possibilité de rouler autour du nœud. En outre est simplifié le montage étant unique le vissage pour bloquer toutes les hampes.The object of the present invention is to remedy these drawbacks. The invention, as characterized in the claims, solves the problem of the joint-fitting by making the hinge joint. Indeed, thanks to the balls concentric, the stems, even if blocked, have the possibility of rolling around the knot. In addition, the assembly is simplified since it is unique, the screwing to block all the stems.

Les avantages obtenus grâce à cette invention consistent essentiellement en ce qu'est la possibilité que présente le joint de pouvoir engendrer tous les systèmes aux grillages spatieux à partir de n'importer quel module à la base, grâce à la possibilité du mouvement des hampes après le blocage. De cette façon on a l'avantage de réaliser toutes sortes de formes soit courbes soit droites. D'autre avantage c'est qu'il est suffisant visser un seul boulon pour bloquer douze et plus hampes (selon le nombre des fentes que les calottes présentent). Cet avantage-ci permet de réduire au minimum les temps de montage.The advantages obtained thanks to this invention consist essentially in what is the possibility that presents the joint to be able to generate all the systems with the spatial grids starting from not importing which module at the base, thanks to the possibility of the movement of the poles after the blocking. This way we have the advantage of making all kinds of shapes, either curved or straight. Another advantage is that it is sufficient to screw a single bolt to block twelve and more shafts (depending on the number of slots that the caps have). This advantage makes it possible to minimize assembly times.

Les dessins (1) répresentent un sistème modulé pour structu res aux grillages spatiaux composé par des joints et des hampes soit obliques soit horizontales. Le mécanisme du joint se compose par deux calottes hémisphériques (fig.16-fig.17) douées de fentes (4) et de troux (5) qui permettent l'introduction des bouts des hampes (figg. 13-14) de sorte que les billes, égales entre elles, convergent à l'interne de la calotte autour d'une bille centrale et se boquent au moyen d'un boulon centrale (fig.15 - n°1) et d'un écrou (fig.l5 - n° 11). Cet écrou est emboîté dans la calotte ainsi que le boulon à tête cylindrique. Les fentes sont douées d'un évasement (fig. 21 - n° 12) en forme de cône pour permettre la rotation des hampes obliques, ainsi que les troux des hampes horizontales (fig.l5 - n° 5).The drawings (1) represent a modulated system for structures with spatial grids composed of joints and stems either oblique or horizontal. The joint mechanism is made up of two hemispherical caps (fig. 16-fig. 17) endowed with slots (4) and holes (5) which allow the insertion of the ends of the stems (figs. 13-14) so that the balls, equal to each other, converge inside the cap around a central ball and lock themselves by means of a central bolt (fig.15 - n ° 1) and a nut (fig.l5 - n ° 11). This nut is fitted into the cap as well as the cylindrical head bolt. The slots are provided with a flare (fig. 21 - n ° 12) in the shape of a cone to allow the rotation of the oblique stems, as well as the holes of the horizontal stems (fig.l5 - n ° 5).

La calotte est douée des nervures externes (fig.15 - n° 6) pour équilibrer les efforts de traction.The cap is endowed with external ribs (fig. 15 - n ° 6) to balance the traction forces.

Conformément à la présente invention, pour favoriser l'intro duction d'un boulon de diamètre plus grand, on peux éliminer la bille centrale (fig.15 - n° 10) et élargir le trou de la calotte (fig.21) selon le diamètre du boulon. C'est évident que dans ce cas change aussi la dimension des billes (figg. 21-22) entre eux.In accordance with the present invention, to favor the introduction of a bolt with a larger diameter, it is possible to eliminate the central ball (fig. 15 - n ° 10) and widen the hole in the cap (fig. 21) according to the diameter of the bolt. It is obvious that in this case also changes the dimension of the balls (figg. 21-22) between them.

En cas que l'on doit réduire le nombre des hampes convergentes, il n'est pas nécessaire d'employer deux calottes pareilles: l'élément de fermeture (fig.22) suffit au blocage.In the event that the number of converging stems must be reduced, it is not necessary to use two similar caps: the closing element (fig. 22) is sufficient for locking.

Claims (5)

1. Le joint "SPACE-VESTRUT" est un mécanisme qui résout des systèmes de construction pour structures aux grillages spatiaux. Il est caractérisé par deux calottes creuses de forme hémisphérique d'épaisseur variable (figg. 16-17) douées de quatre fentes (fig. 16 n° 4), orthogonales entre elles, pourvues d'évasement en forme de cône (figg. 15-21 n° 12), de profondeur telle qu'elles permettent l'introduction des bouts des hampes obliques, en forme d'une bille (figg.13-14), qui loge dans l'évasement. Cette calotte est composée aussi par quatre troux semi-circu laires, eux-même évasés, en face des quels on a créé des nervures externes de radissement (figg.15-16 n° 6) pour équilibrer les efforts de traction (figg. 10-21). La caractéristique des nervures est essentielle en cas des efforts de traction considérables; c'est évident que l'on doit considérer aussi brevetée la calotte (figg. 16-17) dépourvue des nervures. Les troux (fig. 16 n° 5) sont nécessaires pour l'introduction des hampes horizontales et, en autre, ils garantissent le blocage de ces dernières. Les calottes renferment les bouts des hampes caractérisées par des billes liées aux hampes au moyen d'un raccord (figg. 13-14). Les deux calottes sont assemblé au moyen d'une vis;à tête cylindrique avec hexagone emboîté (fig.15 n° 1), la quelle traversé le trou central (fig. 16 n° 2) de la calotte et la bille centrale de convergence de toutes les hampes (fig.15). Cette vis-ci est bloqué par un écrou qui trouve logement dans un incaissement en forme d'hexagone (fig. 21 n°13). Les calottes qui composent le joint "SPACE-VESTRUT", selon la présente revendication, peuvent être aussi de forme différente (fig.18 - fig.22) pour permettre la réalisation des grillages plats ou des plaques aux grillages, plates ou courbes, par un niveau seulement. Tel élément est caractérisé par quatre entailles semi-circulaires les quelles permettent l'introduction des hampes horizontales. 1. The "SPACE-VESTRUT" joint is a mechanism that solves construction systems for structures with spatial grids. It is characterized by two hollow domes of hemispherical shape of variable thickness (figg. 16-17) endowed with four slits (fig. 16 n ° 4), orthogonal between them, provided with cone-shaped flare (figg. 15 -21 n ° 12), of such depth that they allow the introduction of the ends of the oblique stems, in the form of a ball (figg.13-14), which lodges in the flare. This cap is also made up of four semi-circular holes, themselves flared, in front of which external radiation ribs have been created (figg.15-16 n ° 6) to balance the tensile forces (figg. 10 -21). The characteristic of the ribs is essential in the event of considerable tensile forces; it is obvious that one must also consider patented the cap (figg. 16-17) deprived of the ribs. The holes (fig. 16 n ° 5) are necessary for the introduction of the horizontal stems and, in addition, they guarantee the blocking of the latter. The caps enclose the ends of the shanks characterized by balls linked to the shanks by means of a connector (figg. 13-14). The two caps are assembled by means of a screw; with a cylindrical head with an encased hexagon (fig. 15 n ° 1), which crossed the central hole (fig. 16 n ° 2) of the cap and the central convergence ball of all the stems (fig. 15). This screw is locked by a nut which finds housing in a hexagonal shaped recess (fig. 21 n ° 13). The caps which make up the joint "SPACE-VESTRUT", according to the present claim, can also be of different shape (fig.18 - fig.22) to allow the realization of flat grids or grate plates, flat or curved, by one level only. Such element is characterized by four semi-circular notches which allow the introduction of horizontal shafts. 2. Système "SPACE-VESTRUT" selon revendication 1, caracté risé en ce que sont les hampes, composées par un tuyau en acier (ou n'importe quel autre matière) creux ou par barre pleine, dont les bouts sont fournies d'une bille fixée ou démontable (fig.13-fig.14).
La section de la hampe peut prendre toutes les autres formes géométriques, et elles ont toujours la caractéristique des bouts en bille. Le raccord qui lie la bille à la hampe peut être soit extérieur, soit intérieur (fig. 13 - fig. 14). On revendique, de toute façon, n'importe quel sorte de hampe douée d'un bout sphérique qui concourent dans un joint pour structures aux grillages.2. "SPACE-VESTRUT" system according to claim 1, characterized in that the poles are composed of a steel pipe (or any other material) hollow or by solid bar, the ends of which are provided with a fixed or removable ball (fig.13-fig.14).
The pole section can take any other geometric shape, and they always have the characteristic of ball ends. The connection which connects the ball to the shaft can be either outside or inside (fig. 13 - fig. 14). Anyway, we claim any kind of pole endowed with a spherical end which compete in a joint for structures to the fences. 3. Système "SPACE-VESTRUT", selon précédentes revendications, caractérisé en ce que la calotte qui compose le joint peut être douée par un nombre plus petit ou plus grand de fentes, en rapport à celui reproduit dans les dessins. Telle caractéristique permette la réalisation de structures aux grillages spatiaux de n'importe quel géomé trie, y compris des structures géodésiques, étant illimité le nombre des hampes qui peuvent sortir du joint. Cette propriété, pour structures outre mesure compliquées, est associée à la caractéristique des hampes de pouvoir modifier sa propre longueur soit aux hampes horizontales soit à celles obliques,dans la même structure.3. "SPACE-VESTRUT" system, according to the preceding claims, characterized in that the cap which composes the joint can be provided with a smaller or greater number of slots, in relation to that reproduced in the drawings. Such a characteristic allows the realization of structures with spatial gratings of any geometry, including geodesic structures, being unlimited the number of poles which can leave the joint. This property, for overly complicated structures, is associated with the characteristic of the stems of being able to modify its own length either to the horizontal stems or to the oblique ones, in the same structure. 4. Système "SPACE-VESTRUT",selon précédentes revendications, caractérisé en ce que la vis centrale peut varier sa dimension,par suite de l'élimination de la bille centrale,et par consequent en modifiant les diamètres des billes et du trou central (fig.21).4. "SPACE-VESTRUT" system, according to the preceding claims, characterized in that the central screw can vary its size, as a result of the elimination of the central ball, and consequently by modifying the diameters of the balls and of the central hole ( fig. 21). 5. Système "SPACE-VESTRUT",selon précédentes revendications, caractérisé en ce que l'élément de fermeture (fig.22) en cas où se réduissent les hampes convergentes dans le joint.Il est composé par un élément plein circulaire, dans le quel on a retiré des creux hémisphériques pour y placer les billes des hampes (fig.22 n°14).Le nombre des creux hémisphériques peut varier selon la quantité des hampes convergentes.Cet élément est doué lui aussi de l'évasement semi-circulaire (fig.22 n°12).5. "SPACE-VESTRUT" system, according to the preceding claims, characterized in that the closing element (fig.22) in the event that the converging stems are reduced in the joint. It is composed of a full circular element, in the which was removed hemispherical recess to place the beads of the poles (fig.22 No. 14) .The number of hemispherical recesses can vary depending on the amount of shafts convergentes.Ce t element is endowed also of the flare semi- circular (fig. 22 n ° 12).
