| . The present invention relates to a removable shelving intended in particular for stores j; for storing goods or spare parts.

In essence, the shelving relating to the invention includes horizontal bars carried at their ends by rigid ladders. Each i | i scale consists of two vertical uprights joined by horizontal crosspieces. Each post is formed by a tubular profile having a semi-open internal wall with a central slot; continuous and side walls with at least one i,. series of perforations equidistant in height. Each cross that carries at each end at least one lug which is engaged through a perforation of the corresponding upright and which is attached to the latter. The cross member has between its ends! '! * -2-: i ii i means for hooking the edge t r-ansversa1 of the corresponding tablets.

I he “

J

In the present specification, an internal element of the shelving is an element directed towards the interior 5 of the volume occupied by this shelving, while an external element is directed towards the exterior.

! In known shelving of this kind,! each cross member is formed by a metal sheet j arranged vertically between the uprights. The edge ! 10 upper of the sheet is folded horizontally in a rib except near the ends where this edge is cut.

I The lower part of the sheet is folded over on the side | opnosed substantially at 180 ° to fern a branch 'i; narrow with the remaining part. The ends of the; j 15 sheet each carries at least one hooking lug of

’I

t crosses it to an upright. The hooking lug is * Ü cut out of the end and folded to form a hook directed from the side of the folded upper edge. D ’| on the other hand - each upright - consists of a tube bent at 20 to form a tubular and semi-open element whose cross section is T-shaped. The wall! internal of the Sme of the T is split longitudinally (in its middle, while each side wall of the same has identical and equidistant perforations. Furthermore, each shelf or each shelf element is formed by a sheet plane ho- ji;, rizontale whose edges are folded vertically!: l I;! “j * 'î - ji down.

When mounting known shelving, the legs | The sonos sleepers are ngged and hung in the laxeral perlorations of the sentants to connect them and form ladders. 2n in addition, the folded transverse edges of the tables 5 are introduced into the open grooves towards the top of the crosspieces to connect these and form the resins.

ί - • J_-es known shelving mentioned above have 1 * iO drawback, of stable nature. This is so in particular because the pacts of the ends of the transverse beams engaged in the perforations of the uprights without producing a dec of tightening of the transverse beams against these uprights in a transverse direction of said 15 uprights. In other words, when the legs in question are arranged in the perforations of the uprights, the ends of the upper horizontal edge and? folded down crosspieces can rest on the inner wall of the core of the uprights without being blocked; 20 questions. In addition, the aforesaid legs have dimensions t1, disproportionate and too small compared to the crosspieces, the same or the perforations of the amounts, with respect to the latter. In this way, the placement of these legs in these perforations does not provide any lasting and reliable rigidity to the scale obtained and thus to the shelving produced, the slightest play between any mat and the edges of the corresponding perforation! 'aï'1 j-eu.'s ρas to be compensated. After some I under load, these racks sway dirty cross- such sway disturbs the stability! and limits the possible height of these racks.

| 5 The object of the invention is a new department-)! swimming which remedies the aforementioned drawback of the lack of 1 w ***! . ^ stability of known cases and yes in fact improves, these. The current improvement consists essentially of: that the riattes of attachment of the i! 10 ends of the crosspieces can produce a wedge effect on the inner edge of the horn perforations—! of the uprights, so as to effectively create a progressive and effective tightening of the end sections of these crosspieces against these amounts, which-15 which sections are more importantly had i _! in known cases and located both in the upper part and in the lower part of said crossbeams. Since the crosspieces bear against the uprights! by significant wings and under a pressure of progressive application due to the aforementioned wedge effect, 1 ’i. the assembly of the ladder of the new shelving is particularly rigid and resistant to damage even under heavy loads.

For this purpose, in a shelving according to the invention, each cross member is constituted by a metal sheet! vertical tallicue which is flat at its ends but i I. which is folded up and down between them to form i i | i

In this way, each inclined leg of the xraverse cooperated with the corresponding internal edge ec senble.bienenl 10 inclines the perforation of the amount penoar-ü mounting of this cross on this amount, to ensure each time progressive tightening of the wings horizon. the of each crosspiece against the corresponding internal wall | weighting of the rise, which tightening increases besides j :: 15 with the load of the corresponding shelves and rigici-! relies on the assembly obtained.

! 1 To best increase the rigidity of the walls, the scales of the new shelving unit apply in cases where | the loads are extremely heavy or in cases * 120 where the shelving has a great height, the horizontal wings of the cross member applied transversely against the internal wall of the upright can be welded to this wall.

ï \! On the other hand, in the known shelves,! 25 the transverse and vertical edges of the shelves are! engaged in the narrow slots of the sleepers. These I edges are thus attached to it by v being more or less! -! IÎ-; j; i; tightened by the elastic effect of the lower folded edge - t „„ ver £es.

[* The shelving according to the invention improves! ' also 1 ’assembly er the connection these shelves to xm ~ i- verses of the scales these known cases.

10 For this purpose, in the new shelving, each transverse edge of each shelf has two lans | ί; lookouts folded almost at right angles to be slightly directed towards the outside. The two tongues are engaged respectively in corresponding notches on the crosspieces and situated on the side opposite to the horizontal wings. These tabs with these notches constitute - the means for hooking the shelves to the cross member and | ensure each time the support and positioning of each separate shelf constituting the decking, this I20 which facilitates the assembly and disassembly of each cross member.

In practice, in the new shelving, each- | that the transverse edge of each shelf is folded down i over its entire length while being cut out for I25 to form at least two catching tabs.

The shelving according to the invention finally improves the amounts of the scales of known cases. In this case, instead of being T-shaped, the contants of the new shelving are profiles each having a square or rectangular section significantly simpler than that in T and not impeding the recovery of • 5 stored materials. In addition, for re-advantages! 'sistance and aesthetics of the current case, the external wall of the profile of the. upright has a bonnage directed outwards or inwards and extending over its entire height.

5 Each upright 1 is forced by a profile ne- i- tubular but semi-open sections and resulting from; folding of a sheet. The cross section of the container 1 is generally square or rectangular. From; 'ΌεΓ ε £ force, each upright 1 has a wall ex- ί! -jo dull 5, an opposite inner wall 6 and a half: walls the tera 7. The outer wall 5 full has a good! reinforcement bage 8 yes is directed outside | ; and yes extends over its entire height and over a large one! part of its width. The inner wall 6 split long! - 15 tudinally therefore comprises two parts S3nnétriques separated by a vertical slot S making the profile semi-open. Each perforated side wall 7 has at least one series of perforations 10 equidistant in height. Each perforation 10 is elongated in height 20 but is wider in its upper part than in its lower part. For this purpose, the outer edge 11 of each perforation 10 is vertical, while the inner edge 12 is slightly inclined relative to the vertical both downwards and towards the dull ex-edge 11.

Each cross member 4 is formed by a vertical metal sheet 13 which is planar at its ends 14.

_o_ Lös -cartiss superior ec inferior of La tS-Le 13 are οΐί-β & ε at ang ^ e eroit; errcre ses exireaiiés 14 pour 'Γorfîer ms a — le ίίΟΓ ^ ώοη î.ç.1g suoeneurG 1p and a lower horizontal wing 16. Thus, between its extrénités 14, the cross 4 presents a transverse section in L "

Each cross member 4 carries on each end 14, had at least one leg 1? which is cut there and which is folded and folded at right angles to the side of the wings 10 15 and 16 ”In the case chosen, each end 14 is provided with two legs 17. In addition, each leg 17 is slightly inclined relative to the vertical and both upwards and towards the upper wing 15 or downwards and opposite the lower wing 15 16. Each tab 17 is therefore perpendicular to the sheet 13 and to the ends 14, while being oblique to the wings 15 and 16 and while being closer to the upper wing 15 than to the lower wing 16.

Furthermore, on the side opposite to the wings 15 and 20 16, the sheet 13 has stamped notches 18 which form cavities open upwards and which make it possible to place shelves 2 with a width of 10 in or multiples of 10 in. It should be noted that each end 14 of the crossmember 4 also has a notch 18.

On the other hand, each shelf 2 is constituted by a horizontal metal sheet 1S. The Ion-fi -10- gîlvuâinaux edges of the sheet 19 are bent two laws at right angles in the same direction to îornsr of the stiffeners 20. the "transverse edges 21 of the sheet 15 are folded down on all their 3.onguc -on almost at a right angle 5. As a result, each transverse edge 21 is slightly inclined towards the outside, in addition, each transverse edge 21 is cut to form at least two catching tabs 22 also tilted slightly outward from the vertical.

The inter-axes and the widths of the tongues 22 are equal to those and those of the notches 18 of the crosspieces 4.

i> To mount the shelving from the separate elements that constitute the uprights 3. the crossbeams 1 15 4 and the shelves 2, we proceed as follows, i We first make the ladders 1- For this purpose, we engage the legs 17 of the crosspieces 4 in the corresponding lateral perforations 10 of the uprights 3 and they are hooked to the lower edge "e these perfora-i 20 hold 10. Consequently, the inclined tabs 17 bear against the similarly inclined edges 12 of the perforations 10 and in effect exert a wedge on these i edges 12 during their descent.From this fax, the legs 17 co-operate with the edges 12 to clamp the ends—! 25 mites of the wings 15 and 16 of the crosspieces 4 covers the internal walls 6 uprights 3 and for making particularly rigid recesses there.

The uji tongues 22 and the notches 13 provide support and pO " i:: there are shelves 2 on the crosspieces 4.

In this way, the lugs 17 and the perforations 10 constitute the means for attaching the tra-! 10 verses 4 to the uprights 3, while the tabs 22 j · ”; and the notches 18 form the attachment means ce- i. shelves 2 to the crosspieces 4. It should be noted that the progressive tightening of the lugs 17 in the perforations 10 or of the crosspieces 4 on the uprights 3 increases with the spur of these shelves 2 and thus further stiffens the assembly obtained.

To delimit compartments in the 5 shelving of metal sheets Dianes of separation! 23 are engaged vertically through the slots 9 ”20 of the transversely opposed uprights, extending j each time between the latter.

In the case where the load supported by the i; shelves 2 is important or in the case where the height of the shelving is large, the wings horizontal; 25 and 16 of the crosspieces 4 can be welded to the pa-; internal kings 6 of amounts 3 *! f:. It should be noted that the outer walls 5 of the -12- i! uprights 3 can of course be completely flat and do not have the bonings 8.
