ROGER & GALLET S A.

  The present invention relates to a set of elements: .ldular for the realization of light constructions of the arrangement type of showcases, shop displays consisting of a set of junction pieces of ends of a set of pieces of lateral connections, '' a set of shelves, a set of hollow profiled bars, each hollow profiled bar having on the one hand a side wall, two end sections, and of which all the parts can

  be easily assembled without the use of tools.

  Assemblies of this type are already known but only allow the construction of rectangular modules

  or assemblies with reduced angular assembly possibilities.

  The set of elements according to the invention is such that, by varying the length of the profiled bars and the connection angle of the bars between them, one obtains a

  multiplicity of combinations and geometric shapes.

  The set of elements of the type described above is characterized in that, on the one hand, each hollow profiled bar-ecomports at least one longitudinal groove formed in the side wall, and comprises two end sections of which l: ' one shape with the longitudinal direction of said bar an anglec <at most equal to 900 and the other shape with the same direction an angle worth (1800), and that on the other hand the end junction pieces are all identical between them, and are formed by at least two rigid bars S forming between them a double angle of the angle ", and such that the height of said connecting pieces is equal to the largest dimension of the cavity of the bar

dig.

  The following description of an embodiment

  nonlimiting of the invention is made with reference to the accompanying drawings and figures in which: Figure I is a cross section of a first hollow profiled bar, Figure 2 is a cross section of a second hollow profiled bar, l E Figure 3 is an external side view of the pri-fil bar This hollow of Figure 1, lc Figure 4 is an overview of a junction piece of eyxti J itu :, fiâtr- a view dc, emblc of a first side connecting piece 7 ile, the fitu l 6 is a view of an assembly of a second side connecting piece,

  Figures 7a and 7b show the assembly process.

  ge of modules between eu-1, figure 8 is an overview of an example of combination of the various elements, figure 9 is an overview of another

  example of combining the various elements.

  The set of elements includes a set of hollow profiled bars (1) shown in Figures 1,2,3 Each hollow profiled bar (l) has a side wall (2) and two end sections (5) (6) as shown in FIG. 3 for example In addition, there is a set of bars comprising a longitudinal groove (3) formed in the side wall (2) and a set of bars comprising two longitudinal grooves (3) and (4 ), of the same width, said grooves are arranged on either side of the side wall, while having the

  same longitudinal plane of symmetry.

  The side wall (2) can have any shape

  appropriate geometric, for example circular or polygonal.

  The preferred shape of the side wall, seen in cross section, shown in Figures 1 and 2 along a plane AA of Figure 3 for example, is such that it fits into a square and that the groove or grooves are arranged respectively in one of the vertices or in two opposite vertices

of said square.

  Each profiled bar has two end sections (5) and (6) one of the sections of which forms with the longitudinal direction of said bar, a predetermined angle and the other section of which forms with said longitudinal direction

  an angle equal to (180 -0) as shown in Figure 3.

  The side wall (2) of the profiled bars according to the preferred embodiment of the invention comprises at least one planar facet perpendicular to the longitudinal plane of symmetry of a groove of the bar, such as for example the facets (7), (8 ), (9), to improve the stability of the construction and / or the lateral connection of the bars together. The set of junction pieces is composed of junction pieces (10) all identical to each other A junction piece shown in Figure (4) is composed of parts forming between them an angle twice the angle t Each of the two parts is composed of two bars

(11), (13) and (12) (14).

  A connecting means, for example another bar (15) ensures rigidity in the center of the part - and maintains a predetermined spacing in the central region of said part The spacing between the bars (12) (14) and (11) (13) is such that the dimension of the connecting piece is substantially equal to the maximum dimension of the cavity

a bar (1).

  Advantageously, the bars have longitudinal facets (17) to ensure good cooperation with facets (16) arranged on the internal wall of the

  hollow profiled bar as shown in Figures 1 and 2.

  To join two bars together, two bars are introduced, for example (12) and (14) of a Junction piece in the cavity of a first hollow bar, along a plane perpendicular to the longitudinal plane of symmetry of a groove, and the two other bars (11) (13) of said junction piece in the cavity of a second bar

dig.

  In order to allow the junction of a bar of a first type of bar shown in FIG. I to a bar of the second type shown in FIG. 2, the junction pieces (10) are such that the connecting means (15) is disposed in only one of the two planes formed by the bars (12) and (14) or else (11) and (13) Thus in the mounting position said connecting means (15) of the junction piece (10) is located d '' same side of the junction plane of two successive hollow bars In a hollow bar, according to the first type of hollow bar, the depth of each groove

  is less than half the width of said hollow bar.

  In a hollow bar according to the second type of hollow bar, the groove (when the bar has only one groove) or one of the two grooves (when the bar has two grooves) is at least equal to half the width

of said hollow bar.

  The preferred shape of the junction pieces ensures a certain rigidity in the central region and a flexibility of adaptation at the ends, this embodiment is however not limiting and it is not going beyond the ambit of the invention to use a piece of junction of a different shape but ensuring a double angle of connection of the anglec <Using bars (1) of different lengths and junction pieces (10) we can form modules of various polygonal shapes such as for example - the module (18)

Figures 7 a and 7 b.

  To assemble two modules together, either in the same plane or in perpendicular planes, lateral connecting pieces (19) can be used simply by

flat plate shape.

  To assemble two modules along two planes forming an arbitrary angle between them, a bent connecting piece is used at the predetermined angle P

as shown in Figure 5.

  To assemble three or even four modules together, -o-n uses a connection piece with three or four

  branches as shown in Figure 6.

  It would also be possible to also use a plurality of connecting pieces, of smaller longitudinal dimension, for the same lateral connection between two modes. Furthermore, each connecting piece (19) can cooperate with two hollow bars of two neighboring modules or with a bar hollow of a first module and a shelf

by a second module.

  In addition, a set of shelves comprises shelves (20) of variable shapes, the thickness of which corresponds to the

  width of grooves (3) or (4) of hollow bars -

  There are preferably two kinds of grooves (3) and (4), of two different depths in order to facilitate the mounting of the shelves. Figures 7 a, 7 b, 8.9, show some of the many combinations that it is possible

  to achieve with the elements according to the invention.

  Preferably, but not limited to, the different parts are made of molded plastic, each crcuse bar (1) is more particularly made e, l two parts coming from rolling, and glued along a plnn (21) longitudinal and perpendicular to the plane of 13 ongitudinal symmetry of the grooves To obtain a better solidity of the modules, it is also possible to glue the junction pieces (10) in

hollow bars (l).
