Abstract

The invention consists in a space frame system made up of plastic joints and aluminum beams, for the construction of light elements for the interior decoration and outdoors preparations in DIY kit, based on geometries with semi-octahedron and tetrahedron modules. The joint, made of plastic by hot injection process, is made up of two slotted hemispheres and a central plate, joined together through a single screw that allows the simultaneously tightening of eight or twelve plastic terminals, prearranged to aluminum beams, of small diameter and thickness, through cold seaming. The application is the DIY, for the kit construction of light elements for interior decoration (tables, chairs, shelving, false ceilings) and outdoors preparation (gazebos, canopies, glasshouses, garages, hangars) based on geometries with semi-octahedron and tetrahedron modules. The market is the large-scale retail trade. Since the known structures on the market are based on orthogonal geometries (shelving), we can affirm that, for the above-mentioned applications, it doesn't exists something similar to this invention. One of the advantages presented by this invention is that it allows the construction of tables, chairs, false ceilings, gazebos, glasshouses etc, with an extremely simplicity of transport, assembling, disassembling, inexpensiveness and lightness, thank to the universal joint system which allows the beams rotation after they have been locked in the node through one single screwing operation.

Description

"STRUCTURAL SYSTEM MADE UP OF PLASTIC THREE- DIMENSIONAL SPHERICAL JOINTS AND ALUMINIUM BEAMS FOR THE DIY CONSTRUCTION OF ELEMENTS FOR INTERIOR DECORATION AND OUTDOORS PREPARATION"

Description text :

The invention consists of a system made up of spherical plastic joints for space frame structures, and of cylindrical hollow tubeshape beams in aluminum of small diameter and thickness, provided with plastic terminals, for the kit construction of light elements for interior decoration (tables, chairs, shelving, false ceilings) and outdoors and gardens preparation (gazebos, canopies, glasshouses, garages, small hangars).

The assembly of the above-mentioned elements is effected through the assemblage of a series of joints and beams, contained in the kit, with relative instructions and fixing elements to wall and pavement.

The joints and beams internal diameter is constant, while the beams length varies depending on the model to realize.

Joints and terminals are made of plastics and are obtained through the hot injection process, while the terminals are fixed to the cylindrical hollow tubeshape beams in aluminum through external cold seaming.

The geometries on which the realizations illustrated in this patent are based is that of space frames, with a tetrahedron and semi-octahedron basic module.

In each joint can converge from eight to twelve beams simultaneously.

The eight beams joint (Fig. 1) is made up of (Fig. 2) two hemispherical and symmetrical caps (1) each one fitted with four holes at 45°(2), ovoidal impressions, a central hole (4), a unit (5) for the nut housing (6), and by a central plate (7) fitted with holes (8), too, an elevated edge (9) and a central hole (10). The locking of the eight beams (11) is effectuated by putting the terminals (12), seamed to them, in the corresponding holes locking , simultaneously, with the screw (13) the four horizontal beams with internal bolt first (14), and subsequently the diagonal ones with external bolt (6).

The twelve beams joint (Fig. 3) is made up of the same elements, beam and hemispherical caps, as the eight beams joint (Fig. 4), instead the central plate (7) is replaced by a plate (15) fitted with vertical holes (16) to which correspond the ovoidal impressions (17), and with a central hole (18) in which four more horizontal beams are inserted, hidden by the central disk (19). The twelve beams locking is effectuated by putting the central pin in (20) which fixes simultaneously the eight beams through the nut (21) and, subsequently, the other four diagonal beams by through the external nut (22).

The invention is shown further in more details with the assistance of pictures that represented just one way of execution of the several applications and models.

These flasks are also provided with slots to allow both the insert of the node in the central pin, and to fix the structure to the pavement, by pickets (in case of soil) or by chemical or mechanical fischer (in case of more solid surfaces).
