DESCRIPTION:
BRIEF SUMMARY
The invention relates to a collapsible lightweight stand or framework, in particular for display purposes, and of the type composed of substantially square modules disposed in side-by-side and/or superposed relationship and consisting of articulated rods, said modules being individually designed as a boxlike frame having two opposite vertical, substantially parallel module faces and horizontal and vertical lateral faces individually constituted by a scissors-like pair of articulated rods whose ends are pivotally connected with corner joints disposed at one and the other of said module faces, which corner joints at one or both module faces may be common to adjacent modules positioned in side-by-side or superposed relationship, each corner joint being provided with a substantially plane front plate which at its rear side is connected with bearing means for receiving the ends of the articulated rods, said front plate having parallel side edges vertical in the erected condition of the framework.
In DK published patent application No. 148,673B a stand of the above type is disclosed, the individual modules of which in the erected condition, in addition to four scissors-like sets of articulated rods constituting the vertical and horizontal faces of the module, include two sets of diagonally directed rods extending individually from the four corner joints at one module face to a central joint, the rods of the two diagonal sets of rods in a scissors-like manner intersecting each other pairwise, just like the rods of the horizontal and vertical lateral faces. This prior stand is characterized, inter alia, by a symmetrical structure of the modules, thereby obtaining, on one hand, an improved flexibility as regards the adaptation of the framework to the actual conditions on an exhibition site and, on the other hand, advantages in respect of load capability and a reduction of the risk of deformation when erecting and collapsing the framework, and at the same time both module faces may be used for suspending posters.
From GB-A 2181291 a collapsible display stand is known in which each corner joint or node comprises a substantially plane plate having one or more pairs of lugs at its rear side for receiving the ends of the articulated rods of this framework and where each front plate has parallel side edges which are vertical in the erected condition of the framework.
While the use of said prior stand is mainly restricted to the suspension of display posters by suspension means secured to the corner joints at one module face, DK patent application No. 5013/87 discloses a framework design allowing for an extended field of application and a simplification of the modular structure since, inter alia, the use of diagonal rod sets in most cases may be completely avoided. In said prior framework two corner joints in side-by-side or superposed relationship at the same module face are connected via a rail member which at the ends is pivotally connected with the actual corner joints and includes two halves pivotally connected in the middle of the rail element. Thereby, the two halves may effect a pivoting movement with respect to each other between a first position in which, in the erected condition of the framework, they are in substantially linear alignment of each other, and a second position in which, in the collapsed condition of the framework, they are folded together with the pivotal connection in the middle of the rail member displaced in the direction towards the point of intersection of the scissors-like pair of articulated rods of the vertical or horizontal lateral face located therebehind.
By providing one or more modules of the framework with such mounting rails which, in the erected condition of the framework, extend in the plane of one of the module faces, it has been made possible for the purpose of displaying three-dimensional objects to suspend shelves, trays or the like on the stand, in that the mounting rail may without difficulty be designed to support such items.
