Description

System of modular elements for forming a table

technical field

The invention relates to a system of modular elements for forming a table, with a structure comprising support legs and beams, and with means for fastening the working top to the structure.

Background technique

The known desks can be used as a single desk or in combination to organize the available space according to defined work requirements, such as educational meetings, group work or seminars, or individual work in open plan environments or individual offices.

Known tables however generally do not allow quick and repeated real-time reorganization of the available space, but require complex disassembly and reassembly operations. In other words, such operations are carried out on the initially installed furniture, assuming that the furniture is to remain substantially in the initially determined state, until individual elements or the entire piece of furniture are replaced. Different uses of space through rapid transitions of available furniture, for example from a system of single or multiple work tables in an open plan to a single large center table for planning meetings, is often not possible.

In addition, if the working top is damaged, often the table has to be replaced, its lifespan depending on the quality of the material and its strength of use.

Contents of the invention

An object of the present invention is to improve and make easier the modularity of the assembly and disassembly of the system of modular elements used to form the table, so as to obtain a longer service life with the same selected working top material and strength of use , and can change the appearance of the table.

These and other objects, which will become apparent from the ensuing description, are achieved according to the present invention by a system of modular elements for forming a table, characterized in that it comprises a support structure with upper parts connected together by cross-bar members. a pair of struts forming a strut leg, with a beam for connecting said strut legs together at said cross member, and with a cross member coacting with each strut leg and acting at rest on said Clamping elements on the edge of the top surface of the beam to fix it to the structure.

Detailed ways

With reference to Figure 1, the device of the invention can be defined as a system of modular elements for forming a desk, comprising legs of a stand, with two inclined columns 1 connected at their tops by a crossbar 3, on which The two sides of the two sides provide connection means for the crossbeam 5 supporting the working top surface 13. Said connection means for the beam 5 is of the dovetail insertion type, comprising a lower closing seat 7 for engaging with a corresponding end piece 9 of the beam 5 inserted. The end piece 9 comprises a block 10 inserted into the beam 5, and a dovetail insertion portion 12 of a height greater than that of the beam 5, which is flush with the horizontal side of the beam on one side and protrudes beyond the horizontal side of the beam on the other side. Opposite horizontal sides. Said end piece 9 consists of a separately formed part attached to the end of the beam 5 by means of screws 14 . They can also form one part with the beam by suitably shaping their ends.

The modular element system according to the invention also comprises clamping elements 11 for holding the working top surface 13 against the cross beam 5 . This clamping element can be fastened to the cross bar 3 by means of pins comprising push plugs which pass from below through said cross bar 3 and engage their upper ends in said clamping elements 11 corresponding bushing 17.

Optionally, the connection means can also be formed by a screw, the upper end of which is engaged in a threaded bush in the clamping element 11 . To assemble the table, its supporting structure is first formed by engaging the end pieces 9 of its two beams 5 in corresponding seats in the beam members 3 of the two support legs suitably spaced. When the support structure has been formed, the working top surface 13 is resting thereon and held in the correct position by the two clamping elements 11 fixed on the two cross members 3 . In the example shown in FIG. 1 , the bottom 12 of the end piece 9 is shown protruding beyond the lower surface of the corresponding beam.

If the support legs are in the end position, only one clamping element 11 engages in its cross member 3 to fasten a single working top surface 13 (see Figure 2), while if the support legs are in the middle position, two clamping elements 11 engages in its cross member 3 so as to fasten the two working top surfaces 13 resting only on the cross beam 5, as in the case of a single working top surface, while the upper edge of the cross member is at a higher level than the upper edge of the cross beam 5 3. Forming the side housing elements of the working top surface.

If a working top surface of increased thickness is used, but without changing the overall height of the table, the beam 5 can be rotated through 180° or the end piece 9 can be installed around the beam through 180°. In both cases, since the end piece 9 is higher compared to the beam 5 and the asymmetric assembly, the upper surface of the beam, the surface on which the working top surface can be reconfigured, is lowered, so that the working top surface can have a larger thickness of.

The advantage of the modular element system according to the invention is that no work is necessary on the working tops it uses to fix them to the support structure, which means not only making the manufacturing of the working tops simpler but also reversible.

Another advantage is that the working top can be turned over very simply, just by moving and then reapplying the two clamping elements 11 .

Another advantage is that the reversibility of the work top means that the two work surfaces can be different, providing more choices for the user, while standardizing manufacturing and reducing inventory in stores.

Another advantage is that the same type of support legs can be used both as end legs and as intermediate legs, while the cross members 5 have the same length.

A further advantage of the system of modular elements for forming a table according to the invention is that the position of the individual clamping elements and relative support legs can be freely determined along the periphery of the table.

In said embodiment, the clamping elements are rectilinear, as are the crosspieces of the legs of the stand; therefore the working top surface must provide at least one rectilinear portion along its periphery suitable to be held by said clamping elements. At the same time, these working top surface portions adjacent to the straight portion may be of any shape.

If the sides of the working top surface are rectilinear, the working surface can be secured to the support legs along any pair of sides, in particular at any working top surface location. If, instead of it, the straight portion of the working top surface on which the clamping element acts is recessed relative to the adjacent peripheral portion, it is possible to support them with the same support legs so that between two adjacent working top surfaces Provide continuity. Such continuity can likewise be obtained by measuring the holding member such that its length is substantially equal to the length of the corresponding side of the table.

In a variant not shown in the figures, the plug-in connection has walls that engage with each other, closing down so as to lock the crossbar 5 in the desired insertion position of the crossbar part 3 .
