SE458852B - Metallic load carrier pallet - Google Patents

Abstract

The load carrier has frames of strip material which are folded transverse the longitudinal direction of the strip along lines in the plane of the strip. Each frame has an elongate web surface and two legs joined to the webs by folding the strip at right angles. Each frame (1,2) has two webs which, by folding the strip at right angles and towards each other, are each connected to a leg (12,13,22,23). A web (24,25) on one frame is inserted in the second frame so that this web and a second web (14,15) overlap near the legs.

Preferred embodiments The load carrier according to the invention consists of two different frames, of which the first frame 1 and 1 ', respectively, are shown in Figs. 1, 3 and 5 and the second frame 2 and 2', respectively, are shown in Figs. 2 and 4.

The frames are formed of a strip material of eg steel, aluminum, plastic or plywood, however, steel is preferable depending on the advantageous relationship between strength and price. The strip can, for example, be 60 mm wide and 2 mm thick.

The first frame 1 shown in Fig. 1 consists of a web 11, two legs 12 and 13 and two web parts 14 and 15. be 600 mm long, The web can eg correspond to half the length of a standard pallet, the legs can eg be 98 mm, corresponding to a standard pallet normal height minus the belt thickness 2 mm, and life a length corresponding to the belt width 60 mm. In the alternative embodiment shown in Fig. 3, the web 11 ', the legs 12' and 13 'and one web part 14' are identical with corresponding details in Fig. 1 while the web part 15 ' has a length corresponding to the length of the body 11 'minus the length (or width) of the body 14'.

The second frame 2 shown in Fig. 2 consists of a web 21, two legs 22 and 23 and two web parts 24 and 25. The frame 2 is identical to the first frame 1 shown in Fig. 1 except that the web 21 is shorter than life 11. Life 21 can, for example, be 400 mm long.

In the alternative embodiment shown in Fig. 4, the web 21 ', the legs 22' and 23 'and one web part 24' are identical with corresponding details in Fig. 2, while the web part 25 'has a length corresponding to the length of the web part 21' minus the length of the web part 24 ' (or width).

Frames 1 and 2 are rectangular and have been formed by bending the strip material in the main plane of the strip material along lines perpendicular to the longitudinal direction of the material, ensuring that the radii of curvature at the bending points become small. The strip material suitably consists of straight sheet metal strips with a rectangular cross-section, but can consist of other material with, for example, a corrugated shape.

Since the legs 12, 13, 12 ', 13', 22, 23, 22 ', 23' are exactly the same length, the two frames can be manufactured in the same bending machine, which can be of simple construction.

To form a load carrier in the form of a so-called quarter pallet, two frames 1 are combined with two frames 2 into a rectangular unit in the manner shown in Fig. 6 in solid or dashed lines and in the manner shown in Figs. 7 and 8. From these figures it can be seen that the webs 11 and 21 form load-bearing surfaces, that a leg 12 or 13 and a leg 22 or 23 are perpendicular to each other in the horizontal plane and together form a corner, and that a web part 14 or 15 and a web part 24 or forms a foot which is parallel to the load-bearing surfaces. Before joining, the facing surfaces of the webs 11, 21 and the body parts 14, 15 and 24, 25 are glued to each other. By joining the webs and the web parts perpendicular to each other during the joining together without obstruction of the other frame parts, it is ensured that the glue is not scraped off from the mentioned surfaces before they contact each other. By 458 852 10 15 20 25 30 35 4 the distance between the web 11 and the web part 14 and 15, respectively, is exactly equal to the distance between the web 21 and the web part 24re¶> 25, it is further ensured that all adhesive-coated surfaces come into contact with each other. Instead of or as a complement to the gluing, the latter webs and the body parts can be connected to each other, for example by spot welding.

To form a quarter pallet, two frames 1 'and two frames 2' can also be used, as shown in Figs. 9 and 10. Such a pallet becomes firmer than the pallet shown in Figs. 7, 8 but does not enable the pallet to be handled by means of a wheeled support legs equipped pallet lifter.

The pallet formed by the frames 1 'and 2' is mounted as easily as that previously described, however, when inserting one frame into another frame the body parts 15 ', 25' must be removed, which however does not meet any appreciable resistance because the strip material is resilient. After the frames 1 'and 2' are fastened to each other in the same way as described above, the free ends of the web parts 15 ', 25' are connected to the free ends of the web parts 14 ', 24', for example by welding.

The frames 1, 1 ', 2, 2' can also be combined in other ways to provide a quarter stool. Thus, two frames 1 can be used together with and connected to two frames 2 'or two frames 2 can be used together with and connected to two frames 1'.

If a square pallet with a square shape is desired, 1, 1 ', 2 or 2' can be used.

Several quarter pallets of the same type of the type described above can be combined into one full or half pallet (full pallet = four quarter pallets; half pallet = two quarter pallets), the pallets being placed next to each other in the load plane and connected to each other by adjacent legs 12 , 13; 22, 23; etc are glued or welded together. In Fig. 6, solid lines and dashed lines indicate how two pallets are joined together into a half pallet.

Fig. 5 shows how two frames 1 and a flat strip 30 of the same width as the strip material in the frames are joined together into a long frame to form a whole side in a whole or half pallet. The legs 12 or 13 of the two frames 1 are glued, welded or riveted together and the band 30 is attached correspondingly to the body parts 14 and 15 of the frames 1. A long frame extending over the entire length or width of a full or half pallet and built on The same way as the frame shown in Fig. 5 may also consist of the frames 2, 1 'or 2' and a flat band 30.

For reinforcement of the pallets according to Figs. 6-10 and / or to increase the frictional engagement between these and the forks used to lift the pallets, eg rectangular discs made of sheet metal can be connected to the pallets. Fig. 7 shows in dashed lines how a disc 40 with a width equal to the distance between the outsides of the webs 11 or 11 'in Fig. 6 and a length equal to the distance between the insides of the webs 21 or 21' is placed on top of the webs 11 or 11. 'between the webs 21 or 21' and by means of, for example, glue connected to the surfaces 11 or 11 'facing away from the web parts.

For further reinforcement and / or increase of the frictional engagement with lifting forks, a disc 41 can be attached to the inside of the webs 21 or 21 'in the manner shown in Fig. 8, the disc fitting between the insides of the two webs 11 or 11' and covering underside of waist 21 or 21 '. The two boards 40 and 41 can also be attached to each other by eg gluing, riveting or welding.

In the case where boards corresponding to the boards 40 and 41 are to be used for one of the four pallets according to Figs. 7-10, a full pallet extends over two adjacent quarter pallets, whereby both the outside and the inside of such a full pallet are to be covered with boards four boards are needed, while if only the outside or inside is to be covered, only two boards are needed.

For reinforcement and / or friction increase by means of discs, the most recently described discs, such as the discs 40, 41, can be replaced by or supplemented with a single, eg a fully covering disc, which is attached to the life 11, 11 ', 21 or 21 'outsides or on the body parts 14, 15; 14 ', 15'; 24, 25; 24, 25 'outside. Although only a few embodiments of the present invention have been described above and shown in the drawings, it should be understood that the invention is not limited to these embodiments but is limited only by what is stated in the claims.
