Definitions

  • the present invention refers to a carrying structure, particularly conceived for storage shelving.
  • Carrying structures for storing material are already known, in particular those composed by properly spaced vertical - rods and by horizontal stringers restrained at their extremities to two successive vertical rods.Said stringers may be placed at one or more levels in order to support one or more shelves where light goods may be stored directly and heavy goods can be stored making use of pallets which permit loading and unloading by means of high loaders.
  • stringers are provided at their two extremities with couplings made up by two angled walls, forming an L shaped section. They are added by welding and, at least on one wall, are provided with hooks which should wedge in designed seats existing either in the front face only or in the front face and in a contiguous lateral face of the vertical rod.
  • the vertical rods and the horizontal stringers, as well as the welded couplings, are notoriously of shaped, metallic plate.
  • the stringers in particular are produced in differently sealed sections, depending upon the maximum load foreseen for each structure shelf. Hence the necessity, for the firm that makes such structures, to produce different section profiles and therefore to multiply the appropriate equipments.
  • Paint or zinc plating can be done only after stringers completion, the ultimate consequence being a high equipment cost, a limitation in production and an increased cost of the carrying structure components.
  • the present invention refers to a metallic structure,whose stringers do not have welded extremities and are suitable for mass production, also because they can be manufactured from pre-painted or galvanized plate and therefore do not require any operation after their completion.
  • the stringers profile presents only one shape and one sealing, so that every stringer provides strength and stiffness proportional to a foreseen load.Each stringer can be coupled with stringers of the same profile,arranged in parallel and/or superimposed one to the other, thus providing different combinations capable to support differ ent loads as they increase. It is possible therefore, to reduce the cost of production equipments, to increase the current production and to reduce remarkably production costs.
  • the carrying structure of the invention is characterized by the fact that the vertical rods have a rectangular section made up in such a way as to generate a front wall provided with two vertical rows of seats to house wedge--shaped hooks, a back wall also provided with two rows of seats for wedge-shaped joints and two lateral walls of a predetermined width.
  • the stringers present a section having . a vertical core and two horizontal wings; the extremities of each stringer are trimmed in such a way as to obtain.
  • a core extension which, when coupled with the vertical rod, extends along one wall of the rod provided with seats for wedge-shaped joints.
  • Said core extension on its side is characterized in a way to obtain directly upon itself at least two coplanar hooks, vertically spaced of the same amount existing between two seats and therefore suitable to wedge in two consecutive seats of a row.
  • Said structure is also characterized by the fact that the lateral walls of the vertical rod have a width at least double with respect to the inside projection of the stringer wings, so that two identical stringers can be placed side by side parallel and hooked one in the seats of the front wall and the other in the seats of the back wall of the vertical rod.
  • the same structure is also characterized by the fact that the vertical dimensions of the_two hooks, at the extremit ies of heach stringer, do not exceed the section height of the stringer itself, so that two identical stringers can be assembled superimposed and in contact with their contiguous wings.
  • the position of these hooks is such that in said superimposition the distance between the lower hook of the stringer immediately below is equal to the distance between the hooks of a same stringer, so that in the combination between two superimposed hooks, successive seats are respectively occupied by the hooks.
  • the structure object of the present invention is characterized by a stringer 1 and a vertical rod 2.
  • stringer 1 is made up of a shaped plate having cross section including a vertical core 3, an upper wing 4 and a lower wing 5.
  • Wings 4 and 5 are connected to core 3 by means of an extended curvature, respectively 6 and 7, so that wings 4 and 5 form together with core 3, a sort of double T section having however the core offset in regard to the center line wing plane and closer to curvature 6 and 7.
  • core 3 shows a stiffening rib 8,preferably offset in regard to the center line and closer to lower wing 5, for reasons that will be specified later.
  • stringer 1 presents some shearings in order to obtain teeth 9 and 10 needed for the coupling with the respective vertical rod 2.
  • a first square shearing 11 involves the upper wing 3 and a portion of the bending 6, in order to obtain a right angle notch limited by a transversal side 12, designed to rest on the lateral wall of vertical rod 2 (see Fig. 4) and by a longitudinal side 13 which constitutes an extension of curvature 6 and is designed to lean on the front face or on the back face of the same vertical rod 2.
  • hooks 9 and 10 in the phase of coupling with vertical rod 2, are practically brought to rest on the front wall or on the back wall of vertical rod 2, so that they can be safety inserted into the foreesen seats on vertical rod 2.
  • Hooks 9 and 10 are at fixed distance between them, equal for both extremities of stringer 1 ; hook 10, moreover, is placed at such a level as to keep the same distance from hook 9 of another identical stringer hooked below stringer 1 , wing 5 of one of the stringer being in contact with wing 4 of the other, as indicated in Fig. 4.
  • the first advantage is that the joints at the extremities of the stringer, provided with hooks 9 and 10, are obtained by shearing and shaping of the stringer itself, thus eliminating the successive welding operation reagnad by the customary technique. This also permits to work on plates already painted or galvanized, thus totally eliminating successive operations of painting or galvanizing which are required by the previous technique, due to joints welding.
  • Another advantage is due to the fact that, being hooks 9 and 10 enclosed within the profile height, and being the internal projection of wing 4 and 5 not in excess of half the width of lateral walls of rod 2, more profiles can be coupled together and form a unique stringer, as shown in Fig. 4. It may be seen from this figure that a profile 1 can be coupled with a profile 1', counteropposed and parallel, or with a profile 1" placed immediately below.
  • vertical rod 2 is obtained from a plate shaped in a way to assume a practically rectangular section.
  • the longitudinal edges 15 and 16 are bended, a first time on the back side of the vertical rod up to a short distance from the center plane and then bended a second time, to the outside, remaining parallel and leaving between them a predetermined space suitable to receive a transversal bracing profile.
  • Such transversal profile is secured between edges 15 and 16 by means of bolts crossing the coaxial holes 17 and 18 existing on said edges.
  • The.rectangular section of the vertical rod 2 is also composed of two lateral walls 19 and 20, whose width is determined in the following precise way: when two stringers 1 and 1' are positioned in parallel and lean with their cores 3 on the front and back walls respectively, the internal edges of wings 4 and 5 should not interfere, but on the countrary remain spaced or preferably, just coincide, as indicated in Fig. 4.
  • the section of vertical rod 2 also features a front wall 21 provided with two vertical rows of seats 22, equally spaced and able to receive, by wedge-in insertion, hooks 9 and 10 of each stringer.
  • the distance between successive seats 22 is identical to the distance between hooks 9 and l o, and, for the reasons alrealy explained, they may receive, one after the other not only the hooks of a profile 1 , but also the hooks of two or more profiles 1' , 1" ........... overlapped and in contact each to the other.
  • a median rib 23 can be foreseen on walls 21 in order to increase their stiffness.
  • Vertical rod 2 presents in the rear two walls 24 and 25 coplanar and divided by the two edges 15 and 16. These walls are also provided with a respective row of seats 22. The distance between the two rows is identical to the one of the rows existing on the front wall 21, while the distan ce between the successive seats of the same row is equal to the distance between hooks 9 and 10.
  • the rear walls 24 and 25 permit the hooking of stringers 1', 1'' .... parallel to stringer 1, or overlapped and in contact each to the other, in order to provide the various combination of stringers in relation to the loads that the structure must support.
  • two overlapped stringers 1' and 1" are indicated, but it is evident that one more stringer can be placed below, or above, stringer 1 shown in full lines.
  • Holes 26 do exist between the successive seats 22, in order to receive a pin 27 used to restrain hooks 9 and 10 and to prevent the unperceived disjoint of the same hooks, when the structure is under load.
  • hooks 9 a nd 10 existing on stringers 1, as well as the configuration of the related seats 22 existing on vertical rods 2, are ' not prominent for the purpose of the patent and may be replaced by other types of hooks and seats without prejudice for the present invention.
  • the invention is not limited to the embodiment described and illustrated in the enclosed drawings: on the countrary every addition and variation within the reach of an expert technician can be incorporated, still remaining in the spirit and in the object of the present invention.
