Abstract

1. Wall shelves made up of at least two ropes (11) and some shelves (12) one above the other, supported by the free ends (22) of the ropes (12) by means of lugs (18), characterized by the fact that the two free ends (22) are held in place by a rigid tubular right-angle bracket (10) for each rope (11), comprising a horizontal arm and another arm which is vertical and can be fixed to a wall ; by the fact that the right-angle bracket (10) has openings comprising mechanical sections at both ends (13-14 and 16-17) and at the elbow (15) ; by the fact that each rope (11) is housed inside the two arms of the right-angle bracket (10) and brings the two ends of the bracket (10) together to form a triangle ; by the fact that two strands of each rope (11) cross over in the horizontal arm of the right-angle bracket (10) and the two free ends (22) come out of the openings (15 and 17) at each end of the horizontal arm of the bracket ; and by the fact that the rope (11) is guided as it comes out of the bracket (10) by curved grooves in the mechanical sections of the openings.

Description

The invention relates to a wall shelving device constituted by cords or by cables or by strips whose free strands support shelves or display cases.

Known wall shelving devices generally use either consoles directly applied to the wall or consoles fixed on particular profiles, or shelves supported by cords.

Consoles directly applied to the wall or consoles to be fixed on particular profiles have the disadvantage of requiring for each shelf the installation of two consoles and therefore the fixing of numerous anchoring points.

For the shelves supported by cords, this type of shelving is already known, corresponding to the preamble of claim 1.

The shelves are pierced at the four corners, which allows the passage of four cords which will be blocked by retainers (ROTH and ELIENS) the cords are coupled in pairs and then fixed either with a horizontal cable, or could be fixed to the wall.

The four cords can be tightened by pinching in a particular cut made in the shelf board (OSTROM).

The shelves of these devices (ROTH and OSTRCM) must undergo relatively large, delicate and visible machining. They must therefore be made of suitable natural wood. This shelving requires a fairly difficult assembly for amateurs and an adjustment of the complicated and long cord windings (ROTH).

Finally the drawbacks specific to the three devices is that the wall fixing by hooks is much less favorable than the fixing by brackets = the shelves are in contact with the wall hence its deterioration; you have to multiply the number of wall fixings (OSTROM), or put an appropriate device such as a cable (ELIENS and ROTH) or put ring hooks (ROTH) in the wall.

The purpose of the device according to the invention is to avoid these drawbacks. The invention as characterized in the claims solves the problem of the number of consoles per shelf: since this new structure is a shelving of several shelves which are only supported by two identical tubular consoles fixed to the wall.

This invention makes it possible: to use any wood for the shelf, therefore particle wood and especially other plate materials since it can dispense with machining. This invention avoids the multiplication of the number of fixing points and especially their importance; it removes ancillary devices such as cable, or ring hooks in the walls.

The advantages obtained thanks to this invention consist. essentially in that these superimposed shelves, which are not in contact with the wall, allow a balancing of the forces due to the load, which can be relatively large, even when two consoles support several shelves. A single fixing point with screws, the latter working in shear, will fix each of these brackets.

The other advantages of this invention are the rapid change in the spacing of the shelving shelves, the simple, therefore economical, design of the latter and, finally, this set of shelves has an aesthetic appearance adaptable to different styles depending on the shapes and materials used.

In the following, the invention is explained in more detail using the drawings showing only one embodiment. The device is presented in four parts: two or more consoles 10 (fig. I), each comprising a cord II (fig. 1), one or more shelves 12 (fig. I) and a system of retainers for the latter 18 (fig. 2). The console is a tubular square at right angles (fig. 3), the section of which can be circular, rectangular, hexagonal, examples which are not exhaustive. The ends and the middle of this type of square are cut beforehand according to two diametrically opposite generatrices. In these three parts, the 90 ^° bending is carried out mechanically in order to release the cut in part 15 (fig. 3), turning the cuts 13-15-16-17 (fig. 3) to form a grooved bend and with equal radii. The part 14 (fig. 3) which is used to fix the console is drawn up flat and drilled. To carry out this shelving, two consoles are fixed to the wall at the same height, with a spacing corresponding to the length of the shelves. We introduce beforehand, inside each of these consoles, a flexible cable or a suitable cord or a strap which follows the triangular shape of the square, coming to be housed in the rounded parts of the ends 13 and 16 (fig 3) to thus close the square which has become undeformable. The cord circuit inside the console is such that the two ends will come out, one at the front, the other at the rear of the console, in grooves 17 and 15 respectively (fig. 3). This circuit is shown in Figure 4. The function of the grooves is to guide the cords and facilitate their sliding, if necessary, to balance the tensile forces caused by the shelves and their load. The shelves can be provided with holes at their four corners in which the cables can slide. Stoppers placed on the cords 18 (fig. 2) ensure that the shelves are locked from below at selected levels. These retainers will be cable ties annular, tubular or spherical, the central opening of which corresponds to the diameter of the cable or cord 18 (fig. 5). Thus in Figure 9 is introduced into the holes of the boards 12 the sleeve 27 of a knurled mandrel 28 which allows tightening by hand. In FIG. 10, a cylindrical stopper 29 provided with a pointy screw 30 blocks the cord 11. This screw can be replaced by a pointed axis passing right through the stopper. It is also possible to define another class of retainers made from metallic sheets, or from injected synthetic or metallic materials cast or extruded in the shape of a stirrup 20 (fig. 5) and 20 (fig. 7) drilled, on its two parallel faces, of a hole of the diameter of the cord and letting pass this -: 01,. The blocking is achieved by the action of a screw 24 allowing the recoil of the stirrup whose rounded upper and lower holes vigorously block the cord. Another possibility of a device for hanging non-pierced shelves can be made from a jumper somewhat similar to the previous one 21 (fig. 5) consisting of a stirrup 21 (fig. 8) tightened on the board 12 by a screw 25. A housing 31 crimped onto the bracket 21 lets the cable 11 pass which is blocked with the screw 26. A console from a flat tube can be produced as shown in FIG. 6. These consoles will receive strips 32 whose connection with the shelves can be obtained according to the principle of Figure 8. The brackets or brackets are made in one piece but can also be made in several parts, in particular those concerning the curved and curved ends of arcs of circle 13-15-16-17 (fig _o3 ). It is possible to install these prefabricated end caps in the appropriate places, by a slight manual forcing and by gluing. These operations are obviously facilitated by a small difference in diameter. The previous description showed a shelving with two consoles, but it is possible to make arrangements with several consoles, with shelves of different lengths. The consoles can also be combined with the display case support.
