DESCRIPTION:
BRIEF SUMMARY
The invention concerns a set of members intended to form, with a poster in particular, a furniture to display the poster; such a furniture; a unit for packaging such a set and/or furniture; as well as a transport device.
Document EP-A-2311.447 provides for an adjustable and portable display apparatus, capable of being arranged in either a working position or a non working position. In the latter position, the apparatus forms a unit, obtained by folding, for intermediate storage.
Vertical supporting members, for example telescopic, cooperate with vertical structural members to hold up elastic bars. Pivoted connections connect certain members, while structural foot members are provided with protruding pins, dimensioned so as to be housed in vertical elements.
Document DE-U-91.09.866 provides for metal tubes secured by a plastic ring, to obtain an adjustable support for photographs or postcards.
Document U.S. Pat. No. 4,866,866 describes a portable and foldable signboard, having feet connected to a central part by pivot pins. A sheet of fabric or plastic is supported between the central part and the feet, the latter being equipped with sliding points, to be driven into the ground so as to quickly erect the signboard.
Document DE-U-93.01.769 describes a display device ensuring an upright position.
It comprises a foot and side parts and several transversal links. Various supports and a transversal link, such as metal tubes 9 mm in diameter and 590 to 2,500 mm long, are mounted on the foot so as to form an H-shaped frame.
Two cables respectively stretched between the ends of the supports allow for the installation of two U-shaped aluminium sections to hold up the display stand. The foot, the frame and the sections are mutually secured by means of stop rings and/or screws.
Document GB-A-2 277 340 concerns a foldable panel, for road traffic.
The known structures have certain disadvantages.
In general, the weight of such structures, for example in the order of 15 kg, make their handling and transportation difficult. This disadvantage is increased when it is necessary to transport groups of several structures, such as for an exhibition.
In a similar manner, most known structures are inappropriate for postal parcels.
For example, in the case of document DE-U-93.01.769, the components of the device have heterogeneous dimensions, such as a thick and short foot while the metal tubes are thin and long.
Broadly speaking, this creates packaging and/or transportation problems.
In addition, it is common to lose small pieces, such as screws, stop rings or similar.
Such pieces slow down the mounting/dismounting of the structure, and make the latter more complex, heavy and expensive.
With a structure such as that of document EP-A-231.447, which provides for assembly by sliding pins inside tubes, there are risks of ill-timed disassembly or dismounting.
For example, under the effect of a lateral impact towards the exterior of the foot element, the apparatus may collapse, which is dangerous and interrupts the display.
In spite of their weight, certain devices lack rigidity, especially lateral rigidity. The structures equipped with a transversal link between two side parts, or the rectangular frames, tend to have this disadvantage.
The goal of the invention is to eliminate these problems in particular.
It also aims, among other things, to propose a furniture which is: in a practical manner; for the poster.
For this purpose, a first object of the present invention is a set of members intended to form, with a poster in particular, a light furniture to display the poster, by assembling the members without tools; characterised in that the set includes a combination of at least the following:
integrated means of assembly by nesting, such as complementary male and/or female shapes, being provided on each member with a view to assembling, respectively: a base with the transversal member between the two feet; an erecting structure on the base, substantially X-shaped, with each flexible member extending from the knot member; the rod members
