DEVICE FOR A STORAGE RACK

Abstract: A storage rack which is provided with a profiled beam (34). The ends of the beam are cut mainly perpendicularly to the length direction of the beam and are so upset that they have a flat fastening part (35) having a height (H1) exceeding the height (H) of the beam. The flat part has a thickness which is considerably less than the the width of the beam and is provided with means (41) for fastening the beam to the posts (32).

Description: Device for a storage rack This invention relates to a device for a storage rack. Racks for storing pallet goods, elongated material and other types of goods are previously known. For instance, Swedish patent No. 7709506-5 describes a rack for elongated goods having several compartments each being provided with a carriage. The carriages are U-shaped and are provided with wheels guided on rails, which are fastened at the upper part of each compartment. The elongated material is stored in the compartment by putting one end of the material on the carriage, after which the carriage is pushed into the compartment together with the material. The other end of the material is placed on a beam at the frame part of the rack. Conventional racks for pallet goods usually comprise posts which are inter¬ connected by side and back rods extending diagonally. The posts are provided with load supporting horizontal beams on which the pallets are placed. One drawback with* these previously known arrangements is that manu- facturing the beams is complicated since it includes several welding operations. Thus, the beams are made of profiled sheet metal and separate end parts are welded to these beams. The end parts are either provided with hooks co-operating with holes in the posts or with holes to take up screw joints. Each end part is, of course, carefully shaped to transmit loads from the beam to the post. These devices have proved to work well but demand comparatively complicated auto¬ matic welding machines and accuracy when being manufactured. The purpose of this invention is to simplify production and mounting of racks of the type described above and the purpose is achieved by the invention as it is defined in the following claims. Three embodiments of the invention will now be described with reference to the accompanying drawings of which Figs. 1 - 7 show a first embodiment, Figs. 8 - 11 a second embodiment and Figs. 12 - 14 a third embodiment. Fig. 1 shows in a perspective view a rack for elongated goods. Fig. 2 is a perspective view of a beam belonging to the rack. Figs. 3 - 5 are in an enlarged scale cross sections on the lines IE - III to V - V in Fig. 2 and Fig. 6 is a perspective view of a rail of the rack. Fig. 7 is a vertical cross section of a distance means in the construction. Fig. 8 is a vertical projection of the outer part of _ beam with associated post according to the second embodiment of the invention. Fig. 9 is an end view of the beam. Fig. 10 is a horizontal perspective view of the end of the ejN beam and Fig. 11 is a vertical projection of a beam not being completed. Fig. 12 is a front view of a beam and a post according to the third embodiment of the invention. Fig. 13 is a cross section on the line XM - XIII in Fig. 12 and Fig. 14 is a cross section on the line XIV - XIV in Fig. 13. The rack shown in Figs. 1 - 7 which is used for storing elongated goods comprises posts 10 of U-shaped profile having several fastening holes 11. The posts are interconnected by means of side rods 12, beams 13 and rails 14. The rails 14 support U-shaped carriages 15 running on wheels 16 in compartments. The carriages are intended to support one end of elongated goods stored in the compartment. There are also several distance means 17 in the rack. The beam 13 shown in Fig. 2 comprises a C-shaped sheet metal profile having the height H. Both ends of the profile are cut perpendicularly to the length direction of the beam and are then upset so that an outer flat part 18 is formed. This part has a height H, exceeding the height H of the beam and is provided with two fastening holes 19. The beam is fastened to the posts 10 by means of screws. The flat part 18 continues into the C-prof ile via an area 20 having a slightly decreasing height. Thus, a beam is achieved having fastening means which are an integral part of the beam " and which are so shaped that the beam can be very simply fastened to the post. The rail 14 shown in Fig. 6 comprises two tracks 21, each having an outer flange 22, keeping the wheel of the carriage on the rail, and an inner flange 23. The flanges 23 are by means of a diagonal web 24 connected to each other and are provided with several holes 25, by means of which the rails are fastened to the posts 10. By such an arrangement the rails can be turned upside-down when one track for some reason can no longer be used. This arrangement also makes ' the rail stable against turning movement. The distance means 17 shown in Fig. 7 comprises a tube 26 with a pin 27 at each end. The pin is provided with a threaded central hole 28 and has at its outer periphery a comparatively wide groove 29. When the pin 27 has been inserted in the end of the tube, the tube is upset at the area 30, this area been pushed into the groove 29, thereby locking the pin 27 to the tube 26. Also the carriage 15 is manufactured from a C-prof ϊled sheet metal which is so upset that a U-shape is achieved. The upper outer part of the carriage is so upset that there is a double material thickness. The two wheels 16 of the carriage are fastened to a shaft 31 by means of bearings and the shaft 31 is tube-shaped and upset so that it is locked with respect to the branches of the U-shaped carriage as well as to the inner sleeve of the wheel 16. The rack according to Figs. 8 - 11 which is used for pallet goods comprise posts 32 of profiled sheet metal having several downwardly narrowing holes 3 which are placed one above the other. These holes support a beam 34 comprising C-shaped profiled sheet metal which at both ends has a flat part 35 partly wit double material thickness. In said part 35 (see Fig. 10) several U-shaped holes 3 and slots 37 are stamped out, thus forming zones 38 with downwardly extendin tongues 39 and areas 40 therebetween. During a following upsetting operatio several in cross section U-shaped hooks 41 are formed at one side of the fla part 35 of the beam out of the zones 38 and the tongues 39, whereas at the othe side of the beam several projections 42 are formed from the areas 40. Also thes projections 42 are U-shaped in cross section. When mounting the beams the hooks 41 are inserted in the holes 33 in th posts and after pressing the beam downwards it can be locked at the posts in an suitable way. This locking can be effected in a conventional way by means of pin in separate holes or by means of spring-loaded tongues which after positioning th hooks in the posts are inserted in the holes 33 above the hooks 41. The racks according to Figs. 12 - 14 comprise posts 43 of profiled meta sheet with holes 44 which are vertically aligned. These holes support beams 4 which are also made of profiled sheet metal and which at each end have a fla part 46 which is considerably higher than the rest of the beam. In said part ther are a number of aligned projections 47, 47'. These projections comprise in cros section U-shaped parts which project alternately from the front and the rear sid of the beam and are formed by local deformation of the flat part. The pro jections 47 which are at the rear side of the beam are inserted in the holes 44 i one of the vertical lines of holes in the posts so that the outer part of the projections extend from the rear side of the posts. In order to lock the beam to the post a locking pin 48 is used which is inserted in the groove formed between the post and the projections, the locking pin being bent at its upper end in order to prevent it from sliding out. This locking pin has three functions: it transmits moments and transverse forces and locks the beam against unintentional lifting movement. The beams can have any suitable profile, for instance C-shape, U-shape or box-shape and it is also possible within the scope of the invention to dispense with the projection 47' on the front side of the beam.
