Abstract

The connector is attached to a tube and connected to a node when building three-dimensional models for use in geometry or chemistry. It comprises two pairs of half circles, the front pair (1) being at right angles to the back pair (2). The half circles are connected by longitudinal ribs (3, 4) and semi-conical lugs (6) are attached to the front pair. These fit either outside or inside a tube.

De la partie postérieure de chaque demi-anneau antérieur est issue une languette (6) convexe vers l'extérieur qui atteint ou dépasse les demianneaux postérieurs et vient presque rejoindre la languette issue de l'autre anneau au  From the posterior part of each anterior half-ring comes a tongue (6) convex towards the outside which reaches or exceeds the posterior half-rings and almost comes to join the tongue coming from the other ring at

Cette languette est rétrécie et épaissie à sa base.  This tongue is narrowed and thickened at its base.

Sur la moitié proximale de sa longueur chaque languette est étroite (7) puis vers le milieu de sont trajet elle présente une augmentation brusque de sa largeur avec une angulation d'environ 900 (8) puis s'arrondit (9) pour atteindre sa largeur maximale, cette zone de la languette  On the proximal half of its length each tongue is narrow (7) then towards the middle of its path it has a sudden increase in its width with an angulation of about 900 (8) then rounds (9) to reach its width maximum, this area of the tongue

Lors de l'introduction d'un axe dans le "porte-moyeux" si les languettes pénètrent l'axe (c.a.d. si le "portemoyeux" est situé à l'extrémité de l'axe) le tube est comprimé entre les languettes à l'intérieur qui sont comprimées par le tube et les demi-anneaux postérieur qui se plaquent sur la partie externe du tube sous l'effet de la pose d'un moyeu sur le "porte-moyeux" (au repos ces demianneaux ont une forme ovale et sous la pression des "moyeux"  When introducing an axis into the "hub holder" if the tabs penetrate the axis (ie if the "hub holder" is located at the end of the axis) the tube is compressed between the tabs at the '' which are compressed by the tube and the posterior half-rings which are pressed on the external part of the tube under the effect of the installation of a hub on the "hub holder" (at rest these half-rings have an oval shape and under the pressure of the "hubs"

Ces "porte-moyeux" permettent aussi de connecter deux tubes entre eux. Pour cela il faut interpénétrer deux parties homologues des "portemoyeux" avec un rotation axiale relative de 900. Lorsque les deux "portemoyeux" sont interpénétrés les languettes de l'un et les languettes de l'autre se croisent (10). Lors de l'insertion d'un tube à chaque extrémité les parties larges de chaque couple de languette se referment sur la partie étroite de l'autre  These "hub holders" also allow two tubes to be connected together. For this it is necessary to interpenetrate two homologous parts of the "carrier" with a relative axial rotation of 900. When the two "carrier" are interpenetrated the tongues of one and the tongues of the other cross (10). When inserting a tube at each end the wide parts of each pair of tabs close on the narrow part of the other
