In eocordanoa with the Invention and as is evident from the accompanying: drawings, the planar ioad-beanng structure 6 supporting the second support surface 3 may advantageously comprise, on one hand, an armature: 17 configured id m 1 shape and, on the other hand, two tray portions 18 and Iff which are sriOUiated and connected having the ability to: pivot, in the reg-οπ of one of the longitudinal edges thereof, with the armature 17, in the Immediate proximity ofthe central or mainferanch 17 thereof, it being: possible to move said tray portions 18 and 13’ mdependeotly of each other, between a raised position: and a lowered position, by defining id said lowered position the second support surface 5.

Preferably, each tray portion 18 and 18: is formed by a peripheral, underlying frame 11, which is optionally reinforced by braces IS5, and by a piate or panel 20 v^ioh is planar or shaped on the surface for receiving, In a wedge manner,articles to fee supported, resting on said frame 19 and rigidly connected thereto:, furtherrnore, said frame 19 is connected to the mein branch 17’ or to the tere side branches 1F a? the l-shepad armature 17 by at leastfwo pivot connections 21. in order to ladhoe the toroeto be supplied for the lowering and raising; thereof, and optionally to ensuite the maintenance: of the raised position thereof, the container may: further comprise means for assisting in the raising of the trey portions 18. 18:, for example in the form of pneumatic Jacks or springs (not shown).

According to a first variant, each articulated; connection between the planar load-hearing structure 0 and one of the two pairs of posts 3 and 3: consists of an arm 23 Which one of öle ends of the concerned pair of posts 3, 3’ thereof, for example in the region of a bracing element 8 connecting the two posts ;3, 3: in question: forming said pair of posts and. on the other hand to the opposite: end thereof, Of the main branch 17f of the hshaoed atrilafi.rfe 17 of the planer load-beerlng structure 8: dehnlng the second support surface 5, by means of a roller or runner 24 mounted so as to slide in a; slot or groove porion 2§ which is formed in saidmain branch 17‘, while being held in said slot or groove 25 (fig.. 1 to 11).

According to a second variant, each; articulated connection between the planar load-bearing structure 6 and one of the two pairs of posts 3 and 3' is created by the cooperation between, on one hand, a bracing element 9 in the form of a bar, a rod or simiiar, preferably having a circular cross section, connecting the posts 3: and 3’ of the pair in; gaesion and acting as a support forpne of the side branches 17' of the i-shapad anrtature 17 of the mad-bearing structure 8 defining the second support surface 5 and, on the other hand, a rail 28 which is rigidly connected to the hshaped armature 17 and which extends parallel thereto under the mam or central: branch 17’ of this armature 17, the bracing element 8 sliding between the rail 23 and said canbal branch 17’ of the 1-shaped armature 17 during the folding movement of the pair of posts 3 and 3' in question and the movement in which said posts are moved into an upright position, said centra! branch 17' remaining supported in a sliding manner on the bracing element 9 during these movements (Fig. 12 to 21).

Advari^geously, thé rali 26 guiding the bmcing element S during the movements of aiding and moving into an upright position comprises two opposite, folded ends $&amp;% connecting said mite the Fshaped armature 17 and delimiting two end sliding: positions for said bracing: element Θ relative to said armature 17. Furthermore, said bracing element 6 is fitted with a groove or an attached shaped part composing a groove 27, forming a Mower messm, engaging: with said rail 26 and mutually guiding:, one relative to the other, said bracing element 9 and sad rail 26 during the folding movement of the pair of posts 3 and 3’ in question and the movement In which said posts are moved into an upright position, and the movements resulting from the lowering and; the raising of the end or the lateral side#, 6,: of the load-bearing structure 6 that is adjaænttothepafr of posts 3 and 3Ίη question.

Wins, in the two aforementioned variants, the load-bearing structure 6 remains constantly rigidly connected to the base 2 and the posts 4,4’: the container 1 preserving tiesingfe-uait make-up thereat even in the folded state and during movements of folding and moving into ah upright position.

Furthermore, the ioac-beanng structure 6 does not exceed the footprint of the base 2, in either the folded state or the deployed state (posts upright) Furthermore, during the manoeuvre of folding and moving Into an upright position, said load-headog: structure only slightly exceeds the outline: of the base 2.

Said base may optionally further comprise blooks 2s' of the load-bearing structure 6 in the lowered state.

Fudhartnora, I is noted that the second support surface 5 may either extend laterally m tüí asbetween the posts opposite the two pairs of posts 4 and 4 (Fig. 1, 3 and 7). or It may be strictly contained between the four posts 4. 4' (Fig 12 and 20) in accordance with an additional feature of the invention,: the base 2 may comprise, on the right of each member 10 having a U-shaped cross section, a pin dr finger 2‘ surrounded by a: supporting surfdce, allowing the stacking of a first container 1 onto another container f In the folded state, the fingers or pins 3P of the first container 1 being Introduced into the respe<^veSycormspondin§ upper free portions of the members 10 having'&amp; U-shaped cross-section of said other container 1 (Fig. 1 a, 9,17,19 and 20).

Clearly, the Invention Is not limited- to the embodiments described and shown in the accompanying drawings. Modifications are still possible, notably from the point of view of the roske-up of the various elements or by replacement with technical equivalents, but without departing from: the scope of protection of the invention eonferredby the claims.
