The realization of composed rigid and/or articulated structures is required in different sectors of the market: furniture, structure for fairs, gazebo, plays of construction, military logistics, spatial structures, etc.

Background art.

In other modular systems the functions of joint and link have absolved from components realized in fusion or injection. These systems are lacking in profiles with modular lengths available to catalog. The terminations of the profiles are closed normally with closings realized in fusion or injection. All the existing systems have a precise distinction between the elements of junction and bars of connection and the number of different elements results elevated.

Disclosure of invention.

This modular system allows different configurations of rigid or articulated structures using different profiles in different lengths with standard step, from which the technique of extrusion is the best. For each of the groups of profiles there is 13 different elements and for example, taking the side of the square profile (1/3 FIG. 10) equal to 32mm we will have the profiles of the figures (FIG. 10,11,12,13) where A represent the presence of holes for the fixing, B the prominences of fixing that are inserted in the C grooves, D the prominences inserted in the hollows E. The geometry of profiles are important because these allow the elevated number of combinations of the system. The profiles are combined between them with bolts, rivets, connecting rods, glue and other systems because their geometry are adapt to the matter: profile 1 (1/3 FIG. 1) with: 2,3,4,10,13 (2/3 FIG. 26,28,30,31) profile 2 (1/3 FIG. 2) with: 1,3,4,6,7,8,10,13 (2/3 FIG. 18,19,20,21,23,24,27) (3/3 FIG. 53) profile 3 (1/3 FIG. 3) with: 5,9,10,11,13 (2/3 FIG. (3/3 FIG. 52,53,54,55) profile 4 (1/3 FIG. 4) with: (2/3 FIG. 25,27,29) (3/3 FIG. 52) profile 5 (1/3 FIG. 5) with: 3,4,6,7,8,10,13 (2/3 FIG. 24,27) (3/3 FIG. 54) profile 6 (1/3 FIG. 6) with: 2.5 (2/3 FIG. 18,22) profile 7 (1/3 FIG. 7) with: 2,4,5,10,13 (2/3 FIG. 14,24,27) <BR> <BR> <BR> <BR> profile 8 (1/3 FIG. 8) with: 2,4,5,10,13 (2/3 FIG. 15, 27,29,30,31) (3/3 FIG. 53, 54,55) profile 9 (1/3 FIG. 9) with: 3 (2/3 FIG. 20) profile 10 (1/3 FIG. 10) with: 1,2,3,5,7,8 (2/3 FIG. 14,15,24,26,27,30,31) profile 11 (1/3 FIG. 11) with: 3 (2/3 FIG. 19) profile 12 (1/3 FIG. 12) with: 4 (2/3 FIG. 27) profile 13 (1/3 FIG. 13) with: (2/3 FIG. 30,31) (3/3 FIG. 55)

The profiles will be available in a catalog in different lengths and/or cut to measure. The standard lengths for each profiles follow the standard step (in the particular case of the intermediary group this is of 32mm) like consequence of the geometry of the profile 4 that is inserted inside of the profile 3 for get a cubic joint to 6 rows, perfectly symmetrical (3/3 FIG. 52). The profiles 1 and 13 presents extra measures (in the particular case of the medium group is of 28mm and of 38mm) because this need to insert respectively to the extremities of the profiles for allow their connection to 90 degrees.

Description of the problems and of the proposed solution.

Eliminate the necessity of elements for joints and connection made in fusion and use instead only extrused element, guarantees productive advantages for the reduced number of components from manage. This possibility allows, however, of preserved the other productive techniques where these could be economically and technically advantageous. The closings of termination and finish of the profiles, normally realized for injection or fusion, they will also be realizable with the technology of the photo-chemical machining and/or cut laser so that personaiize with graphic solutions the assemble structures. The availability in catalog of the different groups of the different profiles in the varied lengths to standad step makes the system modular once equipped of accessories.

Description of the real advantages of the invention to the state of the existing technical.

The advantages of this modular system are: [a] inexpensive production that reduce the number to few basic profiles, [b] for each profile are scheduled standard lengths with constant variations of step, [c] realization of joints and links combining different profiles between them compatible, [d] use of metallic plate worked with photo-chemical machining and/or with laser for the closing of the extremities of the profiles, [e] joint by pressure between the varieties profiles when they don't <BR> <BR> <BR> come required bolt of block, [n the bolt of block are hidden from a profile of aestheticai finish, [g] the connecting rods, also elastic, are hidden to the inside of the profiles, [h] the profiles of a group can have different dimensions so that it's possible to realize the same structures in different dimensions, [i] the materials with which they will be realizable the components are plastic and/or metallic.

Brief description of drawings: the drawing 1/3 shows the different component of the system where the dimensions are only indicative and in a particular case have represented in scale 1: 1, the drawing 2/3 shows some of the possible combinations inside of a same group, the drawing 3/3 shows the terminations of components with plates and examples of rigid and free joints.

Description of a way of realization of the invention with examples and sketches.

A joint of 6 rows could be realized combining the profile 4 in the inside of the profile 3 both will be long like the side of the profile 10 (particular case of 32mm). The joint are symmetrical from his center and from it could be connecting each of the 6 faces the profiles 1,2 or 5 according to the necessities (3/3 FIG. 52). A free joint could be realized with the profiles 3,2,8 (3/3 FIG. 53), or with the profiles 3,5,8 (3/3 FIG. 54).

Industrial applicability.

In the industry the present universal modular system is not limited in a specific sector, in fact will come true: furniture, structures for fairs, structures for machineries, geodetic structures, gazebo, greenhouses, plays of construction, classifiers, sculptures, exhibitors, pylons for advertising panels, system of signs, residences structures of help, spatial structures, structures for car, structures for theater, structures for afloat floors, etc. Are possible other employment with the addition of other elements like: table of support, wheels, plates of glass, zippers, panels of wood, etc., beyond to all those elements that could adapt the use of the system to particular purposes.

The possibility of have the same group of profiles repeated in different dimension scale but all compatible between them through elements of tubular connection, does of this system an open system in the employment and adaptable to most varied contexts: from that structural to the only aesthetical and allows to effect simulations in reduced scale.
