Definitions
- This invention relates to the sector of self-supporting metal shelving of the "do-it-yourself" type, and relates particularly to shelving which is made up of relatively light thin metal sheets which normally finds application in domestic environments to support books and ornaments of low weight.
- Shelving of the type indicated above generally formed from a plurality of shelves coupled to uprights by means of suitable removable attachment means in such a way that the shelves are substantially horizontal and perpendicular to the uprights is known.
- Connection means can essentially be subdivided into two large families, that of threaded means and that of interlocking connections.
- Threaded means may comprise screws or bolts which can be inserted into holes made in the uprights and the corners of the shelves in order to join them together.
- the bolts exert either a shear force which opposes the weight of the shelves and the objects placed upon them or a friction force between the contact surfaces sufficient to overcome rotation between them.
- connection means involving interlocking, tends to overcome the above-mentioned disadvantages avoiding the use of threaded members and corresponding screwing tools so that connections are made by simple downward pressure from the shelves with respect to the uprights.
- Interlocking connection means generally comprise projecting rods or male members, for example on the uprights, which are capable of acting together with corresponding recessed seats or female members formed for example in the shelves at all the corners thereof, or vice versa.
- connection means of the interlocking type is for example described in Italian Patent 1 282020, in Italian Utility Model Application No. PD95U000059 and in British Patent No. 2,260,481 .
- the shelves are generally obtained from substantially flat, rectangular or polygonal sheets, formed so that they have peripheral edges stiffened by means of one or more subsequent bends approximately at a right angle.
- edges are stiffened by welding, brackets or keys which engage suitable seats or cavities in the edges, in order to overcome deformation of the shelves at the corners where the greatest shear forces and the highest bending and torsion moments are concentrated.
- a disadvantage which arises at the time when such shelves with bent-back edges are packed and transported lies in the fact that generally they cannot be stacked rationally, that is inserted one into another, because of the presence of the continuous stiffening edges along all the sides, and above all in the vicinity of the corners.
- the shelves therefore have to be placed one on top of another, leaving virtually 95% of the volume enclosed between the upper surface and the edges unused, with consequent loss of savings in space during storage and transport.
- a principal object of this invention is to eliminate the abovementioned disadvantages by providing assemblable shelving of the interlocking type which has shelves with reduced dimensional characteristics in storage and transport so as to reduce the costs of storage and transport. Another object is to provide self-supporting sectional shelving with multiple shelves having a simplified geometry so as to appreciably reduce production costs.
- a further objective is to design sectioning shelving with multiple shelves which guarantees good reliability and structural stability despite the fact that thin sheets are used.
- Another object is to provide interlocking sectional shelving which is easy to assemble.
- modular sectional shelving of the interlocking type of the type defined in the foreword which, in accordance with Claim 1 , is characterized in that the shelves have stiffening edges with interruptions or discontinuities between one edge and another at the corners so as to permit two shelves to be coupled together at the same time in the space approximately occupied by only one.
- the interruptions or discontinuities in the shelf edges comprise notches or slots of a size greater than the thickness of the shelf sheeting.
- the shelves can be coupled together in pairs by mutual penetration at the front, reducing the space for storage and transport by about 50% in comparison with that normally required hitherto.
- the interlocking attachment means comprise a series of male members formed on the uprights which are capable of engaging corresponding female members formed at the corners of the shelves.
- the connecting means comprise removable inserts which are capable of being housed in the inside space at the corners of the shelves to restore the continuity of the open corners and to reinforce the connection with the uprights.
- each insert has at least a second female member which can be coupled with a corresponding male member formed in a corresponding upright at the time when the latter is coupled with a first female member in the shelf in which the insert is housed.
- Each insert has a substantially " L" shape which matches the internal surface of the corner of the shelf in which it is housed in order to adhere to such internal surface when it is engaged with the male member of the corresponding upright.
- Figure 1 shows an overall perspective view of modular shelving according to the invention from above with the upper shelf being fitted and with a portion partly removed in order to reveal a detail thereof

- Figure 8 shows a view of the detail in Figure 6 from above
- Figure 9 shows a front view of a length of upright of the shelving in Figure 1 .
- Figure 1 0 shows a transverse view of the upright in Figure 9 sectioned along a plane X-X
- Figure 1 1 shows a perspective view of detail XI in Figure 1 on an enlarged scale
- Figure 1 2 shows a cross-sectional view from above along the plane XII-XII in Figure 1 ,
- Figure 1 3 shows a lateral view in cross-section of a detail of the shelving in Figure 1 2, sectioned along a vertical plane Xlll-Xllt
- Figure 1 4 shows a perspective view of a pair of shelves in the shelving according to the invention coupled frontally prior to packaging.
- Figure 1 illustrates an embodiment of the sectional shelving according to the invention, indicated as a whole by the reference number 1 , which generally comprises a plurality of uprights 2 which can be removably connected to a plurality of shelves 3 by means of suitable interlocking connections, indicated as a whole by reference number 4, in such a way that after assembly shelves 3 are substantially horizontal and perpendicular to uprights 2.
- Both uprights 2 and shelves 3 and interlocking means 4 are preferably obtained from metal sheet, e.g. deep pressed steel of a thickness between 0.3 mm and 0.6 mm, suitably cut and bent.
- metal sheet e.g. deep pressed steel of a thickness between 0.3 mm and 0.6 mm, suitably cut and bent.
- other materials including natural or synthetic non-metals worked using different processes, may be used.
- uprights 2 may comprise lengths of substantially " L"-shaped section so as to form an internal corner S and a longitudinal axis A, which may be provided with longitudinal stiffening grids 2', 2" corresponding to corner S and the edges respectively.
- Several lengths of section may be attached together by means of terminal interlocking joints of a type which is in itself known and similar to those which will be described below.
- Shelves 3 may comprise a flat central portion 5, e.g. having a substantially rectangular shape in plan, provided with edges -which are stiffened e.g. by bending.
- edges -which are stiffened e.g. by bending Preferably the edges along the longer sides are bent twice with respect to central portion 5 and as a result have two sides 6, 7 at right angles, while the edges along the shorter sides are bent only once and have a single side 8.
- Corners 9 of the shelves which in the embodiment illustrated in the drawings are sides at 90°, are in any event of a shape which is complementary to the internal or corner space S of uprights 2. Because of the existence of the broad rib 2' at corner S, corners 9 of the shelves can conveniently be inserted into the internal space of uprights 2.
- Interlocking means 4 may be of a type which is in itself known, and that is may comprise male members 1 0 formed on the uprights at positions which are equally spaced along their longitudinal length which are capable of engaging the corresponding first female members 1 1 formed on shelves 3 at corners 9.
- every first female member 1 1 comprises at least one substantially elongated slot formed on bent edges 6, 7, 8 of each shelf 3 in a position corresponding to that of a corresponding male member 1 0 formed on uprights 2.
- slot 1 1 has a margin 1 1 ' substantially parallel to its edge, that is perpendicular to the central plane 5 of the shelf, and the other edge 1 1 " inclined with respect to the former at an angle ⁇ of between 3° and 8° and preferably equal to approximately 5°.
- Each male member 1 0 may comprise at least a wing-like projection 1 0' formed by cutting and plastic deformation of upright 2 at a predetermined distance from corner S.
- each male member 1 0 comprises a pair of wing-like projections 1 0' , 1 0" , which oppose each other and are substantially symmetrical so as to act on the two edges 1 1 ' , 1 1 " of a corresponding female member 1 1 .
- a single wing-like projection in particular the inclined projection 1 0" acting on the inclined edges 1 1 ", 1 4" of corresponding female members 1 1 , 1 4 may be provided.
- wing-like projections 1 0' , 1 0" extend towards the interior of upright 2 in a direction which is substantially parallel or slightly inclined with respect to the longitudinal axis A of the upright.
- bent stiffening edges 6, 7, 8 of shelves 3 are not joined together but have interruptions or discontinuities 1 2 at corners 9.
- interruptions or discontinuities 1 2 in shelf 3 are obtained by removing corresponding end portions of bent edges 6, 7 adjacent to edges 8.
- edges 8 of another identical opposing shelf can be inserted into the slots so that two shelves can be coupled together substantially in the space occupied by a little more than a single shelf, as clearly illustrated in Figure 1 4.
- pairs of shelves coupled together as described above can therefore be packed and protected e.g. using a film of thermoformable material, reducing the dimensions for storage and transport by approximately 50% in comparison with shelves in the past.
- edge 8 in order that edge 8 can be inserted into slot 1 2, the latter must be bent only once and does not have to be attached to edges 6, 7, eliminating many stages of bending and punching and appreciably reducing the manufacturing time for the shelves and therefore for the shelving as a whole.
- edges 6, 7 and transverse edges 8 of the shelves which are not connected together can open up, further opening angle 9 and prejudicing the stability of the interlocked joint, as a result of shear forces and bending moments.
- interlocking means also comprise removable inserts 1 3 which can be housed in the inner cavity of corners 9 of the shelves in order to restore their continuity and in order to force them against uprights 2.
- Each insert clearly illustrated in Figures 6, 7 and 8, comprises an approximately L-shaped body with arms 1 5 joined at a corner 1 6, in such a way as to adhere to the inner surface of corner 9.
- each insert 1 3 has at least a second female member 14 similar to first female member 1 1 provided in shelves 3.
- This female member 14 may be coupled to a corresponding male member 1 0 formed in a corresponding upright, when such male member 1 0 is inserted into female member 1 1 of shelf 3 in which insert 1 3 is housed.
- lateral arms 1 5 may be provided with bent edges 1 7, 1 8 to increase rigidity and structural strength.
- second female member 1 4 has a similar shape to that of slot 1 1 formed on the shelves, and in particular has margins 1 4', 1 4" which are mutually inclined at an angle ⁇ of between 3° and 78° and preferably equal to approximately 5°.
- wing-like projections 1 0', 1 0" extend towards the interior of upright 2 to a depth C which is greater than the sum of thicknesses Sr and Si of shelf 3 and insert 1 3 respectively.
- wing-like projections 1 0', 10" are elongated. Wing-like projection 1 0' extends in a direction substantially parallel to the longitudinal axis A of the upright, while wing-like projection 10" forms an angle ⁇ of between 3° and 8° and preferably equal to approximately 5° with the former.
- two slots 1 1 on the two sides of the dihedral angle of the shelf and two slots 1 4 on both arms 1 5 of the insert are provided substantially at identical distances from the corners.
- insert 1 3 After insert 1 3 has been housed within a corner 9 of a shelf 3, first and second female members 1 1 and 14 are then lined up, wing-like projections 1 0', 1 0" are then inserted into these and finally shelf 3 together with insert 1 3 is pressed downwards. In this way insert 1 3 is progressively wedged into projections 1 0' , 1 0", with consequent compression thereof towards the inner surface of the corner and therefore the corner S of upright 2. This effect increases as the shelf is pressed downwards, either as a result of its own weight or that of the objects placed on the shelves.
