Abstract

The invention relates to devices making it possible to assemble two, three or four (or more) non-concurring rods. The connection for two rods is designed so as to block the latter orthogonally or at a different but predetermined angle namely from 0 DEG to 180 DEG by a bolt. The connection for three or four rods is designed so as to block the three first generally at a right angle either alone or with a fourth in the bisecting line of the solid angle of the first three with the aid of three bolts. These connections comprise two identical and opposite flanges which have recesses corresponding to the shape of the rods to be blocked. The invention finds its application in the fields of scaffolding, fitting-out structures, furniture, greenhouses, etc.

Description

La pressente invention concerne des raccords permettant l'assemblage ,de façon démontable , par deux , trois ,quatre ou plus , de tiges non con- courantes et faisant des angles prédéterminés entres elles
Les applications sont nombreuses : échafaudages , structures de présentation ,de rangement et de stockage , mobilier 5 serres n vérandas pergolas , etc ...
The present invention relates to couplings allowing the dismountable assembly, by two, three, four or more, of nonconcurrent rods and making predetermined angles between them.
The applications are numerous: scaffolding, presentation, storage and storage structures, furniture 5 greenhouses n verandas pergolas, etc ...

Cette invention comprend deux versions de base S Le raccord pour deux tiges ,bloqué par un élément filets. Le raccord , soit pour trois tiges généra@ement orthogonales soit pour les trois précédentes plus une quatrième dans la diagonale du trièdre formé par les trois premières , blo- qué par trois éléments filetés
Des raccords similaires existent déjà mais ils ne permettent pas de par leur principe de serrage un angle , entre les tiges , différent de SOO pour la première version et ne permettent pas non plus comme dans la deuxième version la possibilité de bloquer une quatrième tige
Le blocage s'effectuedans tous les cas par rapprochement de deux brides identiques et opposées et comportent des empreintes correspondant à la forme des tiges .D'autre part comme les tiges ne sont pas appuyées les unes sur les autres le contact des brides enveloppe les tiges ; il évite donc un appui ponctuel
Ces brides peuvent entre obtenues par moulage en alliages légers ou en matières plastiques chargées ou non
Les caractéristiques plus détaillées apparaitrons dans la suite de la description
La figure I de la planche I représente le raccord à deux tiges en vue extérieure suivant la tige (W)
La figura 2 de la planche I représente le raccord à 4 tiges ; vue exté- rieure suivant la tige (J).
This invention includes two basic versions S The connector for two rods, blocked by a thread element. The connection, either for three generally orthogonal rods or for the previous three plus a fourth in the diagonal of the trihedron formed by the first three, blocked by three threaded elements
Similar connections already exist but they do not allow, by their principle of tightening, an angle, between the rods, different from SOO for the first version and also do not allow as in the second version the possibility of blocking a fourth rod
The blocking is carried out in all cases by bringing together two identical and opposite flanges and have imprints corresponding to the shape of the rods. On the other hand as the rods are not supported one on the other the contact of the flanges envelops the rods ; so it avoids a point press
These flanges can be obtained by molding in light alloys or in charged or uncharged plastics
The more detailed characteristics will appear in the following description

The two-rod fitting (V), (W) shown in Figures 1-3-4-5-6-7-8
and 9 comprises two identical and opposite flanges (1), (2) and a locking bolt (3) located on the axis (S, S '). Each flange has two indentations, (11-21) receiving the stem (V) and (12-22) receiving the stem (W), of corresponding shape
laying on these rods to be tightened. These footprints form an angle α 2 between: -
them; the axis coincides with the bisector of the axes (V'-V) and (W'-W). These are located in two planes parallel to a distance (EA) such that the bolt (3) can pass freely between the rods (I) and (2). Each flange also has two surfaces, (13) and (I4) for the flange (I) and for the flange (2), opposing the rotation of one relative to the other during tightening. each flange is reinforced by ribbing

The connection with three and four rods (J), (K), (L) and (T), shown in Figures 2-I0-II-I2-I3-I4-I5-I6-I7, includes two identical flanges and opposite (5), (6) and three locking bolts (7) -, (8), (9) with axes parallel to the rod (T). Each flange has three indentations, receiving the rods (J), (K), (L), of a shape corresponding to that of the rods to be tightened and a passage hole (54) of axis (T) for the rod (T). The axes of the indentations (51), (5 @), (33) form an angle 3 with the axis (T) and are arranged at I200 between them and at equal distances from the axis (T) The angle ss3 3 will be equal to approximately 54 # 44 'if we want the rods (J), (x)
and (L) are orthogonal. Each flange is reinforced by a ribbing in
dull and comprises on the one hand three surfaces such (55) opposing the rotation of the flanges during tightening and on the other hand three elastic tabs, such (56), pushed in (58) by the heads of the bolts or the nuts that fit
also draws on milling (59). The rod (r) is thus blocked between the
surfaces (57) in three zones for the flange (5) and in three others for the bri
from (6)
Variants of these fittings are possible with more than four rods
