Abstract

Structure for sheets of metal doors, characterized in that it is composed of the following elements: - a basic profile (figures 1 and 2), metallic, which is used on all four sides of the rectangular frame and has the following configuration: - a first pair of longitudinal planes (1), parallel, to a separation slightly smaller than the thickness of the front panel of the door, which are joined by one of their sides to a second pair of longitudinal planes (2) that open outwards forming equal obtuse dihedrals and arranged in inverse symmetry, joining in turn the planes of the second pair, on their other side; to a third pair of longitudinal planes (3), with which they also form equal obtuse dihedrals and inversely arranged, with the same angle on the edge as the dihedrals formed by the first (1) and second (2) plane pairs, with so that the planes of the third pair (3) are joined orthogonally on the other side to the plane of the bottom (4) of the profile, which has, centered on its axis of longitudinal symmetry, a recess shaped like a dovetail (5). ), in which an elastic piece carrying a brush strip (6) (fig. 6) (on smaller horizontal sides) or an elastic joint (7) (fig. 5) with internal air chambers is housed externally (on the vertical major sides), which extends outwards in a wing (8) with sealing and safety functions, to avoid pinching of the fingers if the folding doors are closed by unduly actuating them from their vertical sides; - corner brackets (9) (fig. 3), which are used for the materialization of the four corners of the frame in a single piece, each formed by two equal rectangular prismatic bodies (10), arranged orthogonally, the larger side being its section slightly smaller than the separation between the planes of the third pair (3) of the basic profile, to be able to be introduced into it, for which purpose they present on their external face two longitudinal rectangular recesses (11), whose section is slightly greater than that of the recess in tail of the kite (5) of the bottom (4) of the basic profile, to allow the accommodation of this in said recesses, completing the structure of each corner with two pairs of prismatic projections (12) equal, whose straight section is a rectangle, arranged orthogonally the two of each pair and in parallel planes both pairs, in inverse symmetry to one and another side of the corner and to an interior separation slightly inferior to the distance between the outer faces of the first pair (1) of parallel longitudinal planes of the basic profile which they embrace in the assembly.
