DETAILED DESCRIPTION

(10) With reference to the figures mentioned, a modular shelving system is shown indicated overall with the reference number 1.

(11) The shelving system 1 comprises a first module 19 having supporting feet 2 of a bottom shelf 4 and a top shelf 5 connected to one another by uprights 3 which are made of modular lengths.

(12) The feet 2 advantageously comprise adjustment means for the perfectly horizontal arrangement of the bottom shelf 4 and the top shelf 5 so that each of the uprights 3 is loaded with a peak or axial load so as to obtain a capacity of the shelving system 1 substantially equal to the nominal design load thereof.

(13) The shelving system further comprises at least a second module 20 that can be assembled above the first module 19 or that, as shown in FIG. 1, is alongside the first module 19.

(14) The second module 20 has supporting feet 2 of a bottom shelf 6 and a top shelf 7 connected to one another by uprights 3.

(15) The adjustment means for adjusting the feet 2, as well as giving stability to the shelving system, allow the top shelf 5 of the first module 19 to be made completely coplanar with the top shelf 7 of the second module 20 when in the first or second module 19 and 20 there is a middle shelf 8 between the bottom shelf 4, 6 and the top shelf 5,7.

(16) In the minimum configuration, shown by way of example in FIGS. 1 and 2, the first module 19 has the bottom shelf 4, a middle shelf 8 and a top shelf 5, while the second module only has the bottom shelf 6 and the top shelf 7. The lack of the middle shelf in the second module reduces the overall height of the second module due to the lack of thickness given by the shelf itself between the uprights that are directly connected to one another. In fact, the top shelves 5 and 7 of the first module 19 and of the second module 20 are staggered in height by an amount equal to the thickness of the middle shelf 8 that is interposed between two adjacent lengths of the uprights 3.

(17) Thanks to the presence of the adjustment means the user can adjust the height of the second module 20 so that its top shelf 7 is coplanar with the top shelf 5 of the first module 19.

(18) In fact, to allow this possibility, the adjustment means comprise a truncated cone element 9 adapted to rest on a support plane and a cylindrical element 10 adapted to engage the truncated cone element 9 with a first end 13 and adapted to engage the uprights 3 with a second end 23.

(19) In particular the uprights 3 are made of modular lengths. Each length has, at one end, an external shoulder 30 adapted to be engaged by said end 23 of said cylindrical element 10.

(20) The truncated cone element 9 has an internal thread 15 corresponding to half a turn of a screw.

(21) The first end 13 of the cylindrical element 10 has an external counter-thread 11 adapted to be screwed with the thread 15 of the truncated cone element 9.

(22) In this way, when the user screws or unscrews the cylindrical element and the truncated cone element, he/she reduces or increases the height and adjust the perfect horizontability of the second module 20 so as to make the top shelves 5, 7 of the first 19 and second module 20 coplanar.

(23) Furthermore, so as to facilitate the grip of the truncated cone element 9 by the user, a plurality of ribs 12 is provided that extend along the external surface of the truncated cone element 9.

(24) The conical shape of the truncated cone element provides a larger surface area on which the shelving system can rest giving greater stability to the whole structure and more uniform distribution of forces across the support plane.

(25) The value of the conicity is particularly suitable to allow the modules of the shelving system to be placed alongside one another. In fact, the truncated cone element does not project outside the perimeter of the bottom shelves 4, 6 leading to a smaller dimension and facilitating the positioning of the shelving system modules alongside one another.

(26) The adjustment means further comprise an adaptor ring 17 substantially for adapting the dimensions of the diameter of the cylindrical element 10 to the dimensions of the diameter of the through holes present in the bottom shelves 4, 6. Advantageously the cylindrical element 10 and the ring 17 have mutual retaining means.

(27) The retaining means comprise a plurality of housing seats 21 positioned outside the cylindrical element 10 and a plurality of protuberances 22 positioned on a surface of the ring 17 in contact with the cylindrical element 10.

(28) Advantageously there are also mutual retaining means between the ring 17 and the uprights 3 of exactly the same type as the mutual retaining means provided between the ring 17 and the cylindrical element 10. In particular, various rows of housing seats 21 are provided at various heights along the uprights 3 so as to finely adjust the position of the shelves and compensate for any misalignments between the shelves of adjacent modules.

(29) Furthermore the ring 17 has a cut 18 parallel to its axis S that extends along the whole length of the wall of the ring and facilitates the elastic engagement of the protuberances 22 with the respective housing seats 21 thus allowing a stable and secure coupling between the ring 17 and the cylindrical element 10.

(30) The adaptor ring 17 is inserted onto the cylindrical element 10 when the diameter of the through hole 24 of the bottom shelves 4, 6 is larger than the diameter of the cylindrical element.

(31) In fact, the ring 17 has a collar 16 connected to it with a lateral surface adapted to give greater strength to the collar 16 for the connection with the bottom shelves 4, 6 which, as shown in FIG. 7, rest directly on the collar 16.

(32) In the case illustrated by way of example in FIGS. 5 and 6, the diameter of the through hole 24 in the bottom shelves 4 and 6 is substantially the same size and the diameter of the cylindrical element 10.

(33) In this embodiment, the second end 23 of the cylindrical element 10 engages with an annular flange 14 internal to the through holes 24 in the bottom shelves 4, 6. In this way, the bottom shelves rest directly on the cylindrical element 10, without needing to insert the adaptor ring 17.

(34) The annular flange 14 is clamped between the second end 23 of the cylindrical element 10 and the external shoulder 30 of the uprights 3.

(35) The modular shelving system in compliance with the present invention definitively allows the user to compose shelving with various modules also with an extremely stable longitudinal extension, with a high load capacity and aesthetically pleasing.

(36) The dimensions may in practice be of any type according to requirements and the state of the art.
