FR2485899A1 - SHELVING RADIUS WITH FOLDING-FORMED RIGIDIFICATION PROFILES - Google Patents

Abstract

TO ENSURE A VERY GREAT STABILITY OF THE RADIUS, THE RIGIDIFICATION PROFILE 4 OF ITS LONGITUDINAL EDGES IS SHAPED BY TWO TUBULAR SECTIONS 6, 7 PARALLETS SEPARATED FROM BETWEEN BY A GROOVE OPEN TOWARDS THE BELOW AND THE BOTTOM OF WHICH IS IN CONTACT WITH THE BOTTOM OF THE RADIUS 3. THE RIGIDIFICATION PROFILES 5 OF THE TRANSVERSAL EDGES EACH HAVE A EDGE 12 WELDED TO THE TUBULAR SECTIONS 6, 7 AND PROVIDED WITH A SLOT 14 THROUGH WHICH THE RADIUS CAN BE HANGED TO THE BRACKETS 2 JOINT OF THE UPRIGHTS 1 OF THE SHELVING.

Description

- 1 - The present invention relates to a shelving department comprising

stiffening profiles

  formed by folds along the longitu-

  nominal and transverse of this radius, at least the front longitudinal stiffening profile being in the form of a closed tubular section, in particular a rectangular section, terminated by a flange situated outside said section and in contact with the underside of the radius, while the profiles of

  stiffening of the two transverse edges and a sec-

  angled or in the form of a letter C. A spoke of this kind is described in Utility Model DE 76 30 741. It has the advantage, on the one hand, that it can be assembled with the uprights of the shelving unit without making use of special corner fittings,

  so that it can be easily attached

  table, on the other hand that it presents, especially in the

  field of angles, high resistance to deformation

  mation which allows a direct connection of an amount

  to the other by the ray, because this constitutes in some-

that sort of chaining.

  However, it has proven in practice that when

  the spoke was heavily loaded in its central part

  trale there could be twisting or warping-

  which can lead to undesirable deformations

  rables and unsightly stiffening profiles

  longitudinal, in particular of the external faces of these

  ci located in planes perpendicular to that of

  radius, these deformations further making the installation of

difficult quests.

  The object of the invention is then to create a radius

  of the kind described in the preamble whose shape allows it

  not only to resist the torsional forces

  or warping stiffening profiles along

  but also to support heavier loads.

  To achieve this object, the invention essentially provides

  so that at least the stiffening profile - 2 - of the longitudinal edge is constituted by two parallel tubular sections separated from each other by a groove open downwards, the walls of these sections located opposite one of the other at the same time forming the sides of said groove. An even greater stabilization can be obtained when, according to another characteristic of the invention, the bottom of the groove is in contact with

  support with the underside of the spoke.

  It is further advantageous that the two sections

  tubular constituting each of the rigid

  longitudinal fication have the same height but different widths and that the outer tubular section of each of these profiles has a greater section width than the inner tubular section. It is advantageous for the width of the section of the groove to be smaller than that of the outer tubular section, but larger than that of the

2n inner tubular section.

  It is also important that the edge of the pro-

  stiffening yarns of transverse edges, parallel to the plane of the radius, extends below the two tubular sections of the stiffening profiles of the edges

  and be welded to them.

  Finally, a stable assembly of spokes and

  This is ensured when the edge of the rigid profiles

  difieation of transverse edges, oriented parallel-

  in the plane of the radius includes, in the field of the

  verture of the groove between the two tubular sections a hole or slot through which the spoke can be hung

on the legs of the uprights.

  An exemplary embodiment of the invention is described in detail below and with reference to the accompanying drawing; on the latter - Figure 1 is a schematic view, in elevation, of a rack comprising shelves according to the invention, - 3 - - Figure 2 is a perspective view, from below, of a radius according to l 'invention, - Figure 3 illustrates on a larger scale, in section along line III-III drawn in Fig.2, the radius shown on the latter, and - Figure 4 is a sectional view of the same radius,

  along line IV-IV drawn in fig. 2.

  The shelving shown in fig. 1 consists on the one hand of several similar uprights 1, generally

  four in number, which, at least on their inner side

  lower, have legs 2 obtained by stamping, arranged at regular intervals one above the other along each upright, on the other hand of spokes 3, in this example three in number, held between

  uprights 1 at a distance from one another by means of

very much with the legs 2.

  We see in fig.2 that the rays 3 form the

  along their longitudinal edges of the rigid profiles

  difioation 4 formed by folds and, along their transverse edges, stiffening profiles also formed by folds. At least the longitudinal stiffening profile

  before 4, but preferably the two longitudi-

  nals 4, each consisting of two tubular sections

  closed strips 6 and 7, with four sides, in particular rectangular sections, spaced from one another by a groove 8 open towards the bottom. The walls 6 'and 7' of the two tubular sections 6 and 7 located one opposite the other constitute at the same time the sides

  of the groove 8, while the bottom 8 'of the latter

  niere is in contact with the underside of the spoke

3, thus serving as a support.

  In the same plane as the bottom 8 'of the groove 8 is also located an end flange 9 which also serves as a support for the spoke 3 while being in contact with the underside of the latter. This rim 9 is folded back from

  of the inner wall 7 "of the inner tubular section

  lower 7. At least this rim 9, but preferably also - 4 - the bottom 8 'of the groove 8, can be welded

by points 10 (fig. 2) in department 3.

  We see in fig.3 that the tubular sections 6 and 7 of the longitudinal stiffening profiles both have the same height, but different widths, the outer tubular section 6 of the profile 4 having a width greater than the tubular section interior 7. But it also appears from fig.3 that the width of the groove 8 is smaller than that of the outer tubular section 6, but greater than

  - that of the inner tubular section 7.

  We can see in fig. 2 and 3 that the stiffening profiles of the transverse edges 5 of the radius 3 are each formed by an edge 11 perpendicular to the plane

  of this radius and by a rim 12 parallel to said plane.

  This rim is located under the two tubil.aires sections 6 and 7 of the longitudinal stiffening sections 4 and is welded by points 13 to these sections. Thanks to this arrangement, the resistance to deformation of radius 3 is high, particularly in the field of its angles. We also see in fig. 2 and 4 that the ledge

  12 of the transverse stiffening profiles 5, paral-

  lele to the plane of the spoke 3, present in the field of the groove 8 located between the tubular sections 6 and 7 a slot 14 with the help of which the spoke 3 can be hung on each of the legs 2 of the uprights 1 of the shelving. The fact that these slots 14 are located between

  the two tubular sections 6 and 7 provide stability

  position reading which ensures an indefinite attachment

  ray table 3 on legs 2 of uprights 1.
