Abstract

The blind has a cover (1) fixed to an unrolling drum (2) and a bar (3) parallel to the drum (2) which is connected to command cords (6,7) which in turn are associated with lateral guides (4,5). Each cord is engaged on an unrolling pulley (13,14) coaxial to the drum (2), the pulley axles being solid to an axle (15) which extends freely inside the drum (2). The axle is only connected to the unrolling drum via a spiral spring inside the drum, one end of the spring being attached to the drum, the other end of the spring being attached to the axle.

Description

La présente invention concerne un système de profilés placés dans les dallages, destiné à assurer à la fois la libre dilatation entre les différents blocs de dallage, la liaison verticale tangentielle entre les bordures de ces blocs de dallage et le renforcement des angles de dallage. The present invention relates to a system of profiles placed in the pavements, intended to ensure at the same time the free expansion between the different paving blocks, the tangential vertical connection between the edges of these paving blocks and the strengthening of the paving angles.

Les systèmes actuellement connus permettent la dilatation des blocs de dallage mais n'assurent pas la liaison verticale des bordures. Le plus souvent, ces dispositifs connus constituent une charnière entre les bordures ou bien sont tels que les retraits de séchage des différents blocs de dallage provoquent des jeux verticaux dans les liaisons entre blocs, permettant ainsi les déplacements relatifs des deux bordures adjacentes, et la détérioration prématurée du dallage. Enfin, aucun des systèmes connus n'assure la transmission d'efforts verticaux entre profilés orthogonaux à leur jonction à l'angle des blocs de dallage. Currently known systems allow the expansion of the paving blocks but do not ensure the vertical connection of the edges. Most often, these known devices constitute a hinge between the edges or else are such that the drying shrinkages of the different paving blocks cause vertical play in the connections between blocks, thus allowing the relative displacements of the two adjacent edges, and the deterioration premature paving. Finally, none of the known systems ensures the transmission of vertical forces between orthogonal profiles at their junction at the corner of the paving blocks.

Le système de profilés, objet de la présente invention, permet à la fois la libre dilatation horizontale et la liaison verticale entre bordures des blocs adjacents. Il comprend des profilés "A", disposés en quadrillage pont la section transversale se présente sous la forme générale d'un oméga, les hauteurs des parties "B" et "C" étant sensiblement identiques, de façon à assurer une égale résistance à la transmission d'efforts verti càux entre les bordures "D" et "E" des blocs de dallage, la hauteur "F" étant inférieure aux deux précédentes d'une quantité égale à la tolérance G de planimétrie du support "H". Les parties horizontales "I" du tenon sont parallèles, assurant ainsi une liaison verticale entre bordures, quel que soit le jeu de retrait "J" entré blocs.Les profilés comprennent à leur partie supérieure un ourlet "K" destiné à recevoir le jambage de fixation "L", et à la partie inférieure un talon ' " destiné d assurer la rigidité longitudinale du profilé, talon situé au côté opposé au tenon, de façon à ce qu'un défaut ponctuel "G" de planimétrie du support "H" ne se traduise pas par une diminution de la résistance à des efforts tangentiels situés en "N", la hauteur "F" étant inférieure -à la hauteur "Fl",-elle-même égale aux hauteurs de "B" et de "C".  The profile system, object of the present invention, allows both free horizontal expansion and vertical connection between the edges of the adjacent blocks. It includes profiles "A", arranged in a grid pattern, the cross section is in the general form of an omega, the heights of the parts "B" and "C" being substantially identical, so as to ensure equal resistance to transmission of vertical forces between the edges "D" and "E" of the paving blocks, the height "F" being less than the previous two by an amount equal to the tolerance G of planimetry of the support "H". The horizontal parts "I" of the post are parallel, thus ensuring a vertical connection between the edges, whatever the set of withdrawal "J" entered blocks. The profiles include at their upper part a hem "K" intended to receive the jamb of fixing "L", and at the bottom a heel "intended to ensure the longitudinal rigidity of the profile, heel located on the side opposite to the tenon, so that a point defect" G "in planimetry of the support" H " does not result in a reduction in the resistance to tangential forces located in "N", the height "F" being less than the height "Fl", - itself equal to the heights of "B" and "C ".

Ces profilés sont assemblés à leurs extrémités par des pièces de liaison "P" assurant la transmission d'efforts vert,- caux entre profilés orthogonaux, s'emboitant sur chacun des pro fiXés orthogonaux "A". Ces pièces "P" comportent deux sections successives "Q" et "R" en oméga, symétriques par rapport à l'axe S, s'emboitant sur les sections des profilés "A", et sont pliées autour de l'axe de symétrie "S" à 90 , soit dans un sens pour donner la pièce en liaison "T", soit dans l'autre pour donner la pièce de liaison "U", de façon à permettre un emboitement sur les profilés "A" sans jeu, la meme pièce permettant ainsi par pliages différents un emboitement sur lesprofilés, solidarisant les angles de blocs de dallage. These profiles are assembled at their ends by connecting pieces "P" ensuring the transmission of green forces, - wedges between orthogonal profiles, fitting onto each of the orthogonal profiles "A". These pieces "P" have two successive sections "Q" and "R" in omega, symmetrical with respect to the axis S, fitting onto the sections of the sections "A", and are folded around the axis of symmetry "S" at 90, either in one direction to give the connecting piece "T", or in the other to give the connecting piece "U", so as to allow an interlocking on the profiles "A" without play, the same part thus allowing by different folds an interlocking on the profiles, joining the angles of paving blocks.

Le système ainsi constitué permet donc la libre dilatation des blocs de dallage, assure, quel que soit le retrait des blocs de dallage, la solidarité verticale des bordures, assure la solidarité des profilés orthogonaux à leur jonction, en empêchant tout décalage vertical des bordures susceptible de provoquer leur ébrèchement au moment du passage des charges.  The system thus formed therefore allows the free expansion of the paving blocks, ensures, whatever the removal of the paving blocks, the vertical solidarity of the edges, ensures the solidarity of the orthogonal profiles at their junction, preventing any vertical shift of the edges likely to cause their chipping when the loads pass.
