Definitions
- the present industrial invention concerns a collapsible bearing structure with vertical extension, particularly for platforms and floor boarding.
- Such articulation joints comprise a square shape block that on one of its larger faces shows four cavities, open towards respective side walls of the block, destined to the housing and hinging of respective tubular elements, in such a way as to enable the articulated coupling of four tubular elements developing on planes orthogonal to each other.
- these joints can have a through hole perpendicular to the face provided with the aforementioned cavities, which can be used for the coupling with a further tubular element.
- pairs of tubular elements, articulating in the structure define planes respectively perpendicular and parallel to the floor and bearing plates are laid and fixed on the latter, maintaining the structure in the desired position.
- Object of the present invention is to realise a vertical extension bearing structure that would allow to support even considerable loads and that would also be collapsible parallel to the floor for its folding to conditions of minimum volume.
- An additional object is to enable the overlaying and fixing of several similar structures for the formation of modular composite structures.
- a vertical extension collapsible structure particularly for platforms and floor boarding, comprising pairs of tubular elements that intersect at mutual hinging points inside vertical planes perpendicular to each other and have their ends hinged in respective cavities present on a larger face of respective articulation joints, each one of said articulation joints being provided with a central through hole perpendicular to said larger face, characterised in that it also comprises vertical telescopic elements with ends positioned as abutting in said central holes of respective articulation joints.
- the telescopic elements assume a minimum fixed length, and they set themselves in a stable way between each pair of articulation joints located on the same vertical, thus guaranteeing the solidity of the structure.
- the collapsibility of the structure is possible, since the telescopic elements adjust their length to the increased distance between the articulation joints to which they are coupled, thus allowing the lateral folding of the structure.
- Two structures thus formed can be overlaid modularly in order to vary the height of the global structure.
- each telescopic element comprises two tubular elements having different diameters, slidingly engaged with each other, at least one of which is provided with fixing means.
- the consequent fixing of a complex structure is obtained by coupling respective telescopic elements belonging to two different structures.
- a structure thus obtained is suitable for innumerable uses, in particular for the realisation of foldable bearing structures.
- articulation joints 2 are in fact blocks of substantially square shape and in one larger face they have four cavities 5 suitable to house the tubular elements 4.
- tubular elements 4 are hinged to said cavities 5 by means of pins 8 that are inserted in the cavities 5 by means of through holes located on the lateral walls of the cavities 5.
- the articulation joints 2 are also provided with a central through hole 6 perpendicular to the two larger faces of the joint 2.
- This hole 6 makes possible the introduction of one end of a telescopic element 3, that sets itself perpendicular to the face of said joint 2.
- the through hole 6 is provided with a narrowing (11) on the inside, which is suitable to form limit stop abutment for the end of the telescopic element 3 inserted into the same hole.
- each telescopic element 3 is formed by two tubular elements 3a and 3b, which can slide one inside the other.
- the distance between pairs of joints 2 located on the same vertical is determined by the presence of the telescopic elements 3. Indeed, in an operating condition the internal tubular element 3a is completely inserted into the external tubular element 3b and therefore the latter positions itself in a stable way between two articulation joints 2 of the structure 1.
- Structures 1 realised in this way are modularly assemblable in order to obtain a global structure, as illustrated in Figures 1 and 4 that comprises two overlaid structures 1.
- the fixing of the global structure thus obtained is done by coupling of the external tubular elements 3b through respective pairs of articulation joints 2 as it is evidenced in Figure 2.
- said coupling is obtained by means of fixing means 9,10, which said telescopic elements 3b are provided with.
- said fixing means can be screw means, respectively male and female, that engage with each other inside the holes 6 of the articulation joints 2.
- the structure according to the invention is therefore utilisable to bear consistent loads, but it involves a minimum volume when closed.
