Definitions

  • the present invention relates to a device for interlocking complementary pairs of components of sets of shelves made of metal plate.
  • These light sets of shelves are substantially constituted by uprights which are optionally reinforced by cross-members and whereon the shelves are fixed at various elevations.
  • the shelves and the uprights are coupled mainly by means of bolts through facing holes of the components.
  • the coupling is hardly ever rigid enough to make the structure become self-supporting, and therefore it is often necessary to provide safety anchoring to the wall, for example through hollow wall fasteners.
  • the coupling between the shelves and the uprights is performed by interlocking tabs formed on the shelves at the vertical regions of their edges and holes formed on the uprights.
  • the tabs are formed by blanking and bending and cantilever out downwards from a region which is arranged horizontally and where they are joined to the shelf and enter the holes of the upright, straddling said holes and thus resting on their lower edges.
  • the tabs are therefore subjected, during use, to considerable shearing stresses which considerably limit their overall load-bearing capacity.
  • the structure is not particularly rigid and therefore self-supporting; it is therefore necessary to provide, particularly at the sides, cross-members for joining pairs of uprights.
  • a principal aim of the present invention is to provide a device for interlocking complementary pairs of components of sets of shelves made of metal plate, which eliminates the above described drawbacks of conventional devices, particularly aiming at considerable ease of assembly and disassembly and improving mechanical strength so as to make the structure become self-supporting.
  • a consequent primary object of the present invention is to provide a coupling device which is competitive in terms of costs and production times with respect to conventional coupling devices.
  • Another important object of the present invention is to provide a device which maintains the interlock over time without changes.
  • Another object is to provide a coupling device which can be easily adapted to the various existing sets of shelves.
  • Another object is to provide a device which can be manufactured with conventional equipment and facilities.
  • a set of shelves made of metal plate is generally designated by the reference numeral 10 and comprises, in the case being considered, four composite uprights 11 and a set of shelves 12 coupled thereto.
  • each upright 11 is formed by two elements 11a and 11b which are aligned and interlocked by coupling devices according to the present invention.
  • the uprights 11 conveniently have an L-shaped cross-section and have, at the folding edge and at their outer edges, shaped portions, designated by the reference numerals 13 and 14 respectively, which form longitudinal reinforcement ridges.
  • the shelves 12 are instead constituted by a rectangular metal plate wherein the longitudinal edges 15a and the transverse edges 15b are folded down so as to form a C-shaped profile.
  • the uprights 11 are rested against the shelves 12, or viceversa, since the portions to be coupled are arranged on two mutually perpendicular planes, particularly the vertical regions 16a and 16b of the edges 15 of the shelves 12 and wings 11c and 11d of the uprights 11.
  • Each coupling device comprises two male elements, each designated by the reference numeral 17, which are shaped like an elongated straight wing, one male element being provided in each one of the wings 11c and 11d of an upright.
  • each upright 11 has a plurality of pairs of male elements 17 conveniently spaced from each other in order to allow to choose the level of each shelf from the ground.
  • the male elements 17 of each pair are arranged at an angle and converge downwards with respect to the intersection line of the planes of arrangement corresponding to the planes formed by the wings 11c and 11d and are coupled thereto along their length and therefore cantilever out laterally.
  • the coupling device comprises two slotted female elements 18 shaped and arranged complementarily to the male elements 17 and provided on each shelf 12.
  • Each one of the female elements 18 has a portion 18a on the corresponding vertical flat region 16a or 16b of the edge 15 and a portion 18b on the longitudinal or transverse horizontal flat region 19a or 19b of said edge 15.
  • the portions 18a have an edge 20a converging downwards and meant to interact, by resting contact, with the male element 17, whilst the portions 18b have an edge 20b lying at right angles to the bisecting line of the angle between the wings 11c and 11d of the uprights 11.
  • Interlocking occurs by resting the corner of the shelf 12 against the upright 11 so that the female elements 18 are arranged above the male elements 17 and by then sliding them mutually to achieve interlocking.
  • Figure 6 shows that the coupling of the components 11a and 11b of each upright 11 is also provided by means of devices composed, like the previous ones, of male elements, now designated by the reference numeral 117, and female elements, now designated by the reference numeral 118.
  • the female elements 118 are only partially slotted and do not have the horizontal portion, since coupling occurs end-to-end.
  • the component 11b provided with the male elements 117 has a flared end 21.
  • a structure is obtain which is particularly rigid and self-supporting without the cooperation of elements other than the interlocks.
  • the structure is so rigid that it does not require cross-members for connecting the various uprights.
  • the materials employed may be any according to requirements.
