No. 2%,719 Claims priority, application France, July 26, 1%2, 95,17 1 Claim. (Cl. 52-732) The present invention concerns vertical elements or uprights consisting of steel cores with light-alloy sections.
An upright is formed by equipping the core, i.e. by slidably engaging therein one or two light-alloy sections each formed with at least one longitudinal series of aligned holes, each hole being disposed between adjacent longitudinal ribs projecting to the exterior.
According to the present invention, the sections fit in cavities formed in said cores and communicating with the outside through rectilinear gaps through which the ribs of said sections project.
With this construction particularly strong uprights can be made which are especially suitable for constructing rack or like collapsible pieces of furniture intended for supporting relatively heavy loads.
The features and advantages of this invention will appear more completely and clearly from the following description given by way of example with reference to the accompanying drawings, in which:
FIGURE 1 is a section taken across the steel core;
FIGURES 2 and 3 are cross-section and front elevational views, respectively, of a light-alloy section, and
FIGURE 4 shows in cross-section an upright consisting of a steel core in combination with a pair of lightrnetal sections.
There is provided a core consisting of two channel shaped elements assembled symmetrically to form a web 1 as shown in FIG. 1. The assembly may be effected either by spot-welding or by bolting. The web 1 has at each end a pair of opposed channel-shaped flanges 1a and 11) forming tubular recesses 2a. The free marginal edges of each pair of opposed channel-shaped flanges 1a and 1b are spaced from each other to provide a rectilinear gap 7.
In each recess 2a a double-rack light-alloy section 3a, shown in FIGS. 2 and 3, is engageable in smooth sliding contact. The section 3a has formed on its front face two rows of holes 4 having lateral ribs 5 and 6 disposed on either side, the holes 4 being long enough and sufficiently spaced from one another to receive bracket suspension hooks of relatively large dimensions.
FIGURE 4 shows an upright consisting of a core 1 associated with a pair of light-alloy sections 3a. On each section 3a the ribs 5 and 6 project externally through the rectilinear gaps 7, the gaps 7 permitting access to the holes 4.
What I claim is:
An upright element for constituting convertible, superposable and juxtaposable pieces of furniture adapted to be quickly assembled and disassembled, said element comprising a core and at least one light-alloy section, said core consisting of a web having a pair of opposed channelshaped flanges forming a tubular recess at each end of the Web, the free marginal edges of the opposed channelshaped flanges being spaced from each other to provide rectilinear gaps, said light-alloy section slidably engaging one of the tubular recesses of said core and having at least one longitudinal series of holes and longitudinal ribs disposed on either side of the longitudinal series of holes, said ribs projecting to the outside through the rectilinear gap of said recess whereby said rectilinear gap permits access to said holes.
