Problems solved by technology

As a result, the structure formed by the union of multiple mutually orthogonal tubular bodies means that there are as many protruding collars as there are straps; such collars can form dangerous points for personnel handling the structure

Embodiment Construction

[0017] With reference to said figures, the positive locking device of the present invention is applied to two metal tubular elements oriented orthogonally to each other and partially bounded by a "U" shaped band, as described in EP 1,516,559.

[0018] Said tubular elements, indicated respectively by reference numerals 10 and 12, have a quadrangular cross-section and are practically provided with a plurality of shaped depressions 14 along the faces constituting their side surfaces, along the opposite and parallel sides of each "U"-shaped strip. Complementary protrusions 16 formed on the inner faces of the branches 18, 20 engage within the plurality of shaped recesses 14, each "U" shaped band at image 3 is generally indicated by reference numeral 22 . The shaped depressions 14 and protrusions 16 are obtained by molding the sheet before bending it and before longitudinal welding of the section bar, which gives a quadrilateral cross-section, and in figure 2 Indicated by referen...

Abstract

A device for the forced locking of two elements oriented orthogonally to one another, especially suitable for steadily connecting and constraining two tubular elements with quadrangular or polygonal section which are partly delimited by a U-shaped band and which have, on at least one face, a plurality of pairs of shaped recesses, whereas the band is correspondingly provided with pairs of complementary projections developed projecting on the inner front of the opposite vertical and parallel branches thereof. The device further includes a bush, extending between the branches of band and fitted, at one end, on a collar which develops projecting along the inner front of branches, whereas the opposite end of bush constitutes the inlet for a screw the end whereof engages in a threaded hole delimited by the collar, bush being extended transversally in the tubular element, provided with aligned holes along two opposite faces, starting from a hole of the band.

Description

technical field [0001] The invention relates to a device for positive locking of two elements oriented orthogonally to each other. More specifically, the invention relates to a device as defined above, in which the elements oriented orthogonally to each other consist of a metallic tubular body with a quadrilateral or polygonal cross-section, which is passed on at least two faces by means also of metal. "U" shape with restrictions. Said tubular body comprises, on at least two opposite faces, pairs of shaped recesses suitably spaced from each other, wherein corresponding protrusions made on a "U"-shaped strip abut. Background technique [0002] A solution of this type for the manufacture of modular pergolas is known from EP 1,516,559 of the applicant, in which the tubular bodies are oriented orthogonally to each other and which comprises a transversal insertion into the tubular bodies Inner shaped pins to secure the straps in place. Said pins comprise opposite conical regio...
