Abstract

1.fitted arrangement of the functional elements for folding doors, which are constituted by panels or slats suspended from a guide rail and articulated by hinge-hinge and cross springs in transverse arrangement, characterized in that the hinge-rivets make up a rectangular prismatic body flattened, with its flat, parallel and larger faces, the inner being narrower, determining an isoscelic trapezoidal prominence with lateral faces inclined at an angle close to 30º, it being provided that said hinge-rivets are crossed by metal sockets, in correspondence with the existing springs in the slats, each of them being constituted by a thin plate that extends its ends symmetrically in respective elongated flanges, which become hooked forms open towards the outside to act as fixing points with the springs of the slats, remaining coincide entities with the edges of the central prominence of the jonquil. 2.defined arrangement, according to claim one, characterized in that the profile of support and guidance of the various constituent slats of the door, preferably made of plastic material, is constituted by an elongated body of prismatic shape and rectangular section, completely hollow in its interior, and provided with a channel centered on its base and along its entire length, to the effect that the sliders or elements of translation of the slats run through it. 3. Improved arrangement, according to previous claims, characterized in that each of said sliders, preferably made of nylon, is constituted by a piece whose shape comprises two opposed spherical caps, of low height and which are joined at the curved part by an asparagus of relation, said piece being provided with an axial bore for passage of a screw that secures the corresponding blade, it being provided that one of said caps, precisely the upper one, is inserted inside the rail, while the central stud is positioned in the channel provided at the base of the rail itself, whereby each slider contacts the guide rail only on the upper edges of the channel and at two diametrically opposite points of the upper spherical cap that runs inside the rail. 4. Improved arrangement of functional elements for folding doors. (Machine-translation by Google Translate, not legally binding)
