So far, most of the pallets are made of wood, but also of metal. Lately appear increasing Plastic pallets on the market. Plastic pallets are relatively expensive because pallets are large in size that can only be produced in very expensive forms and very expensive machines for their production are needed. For this reason, attempts have been made to make pallets from a variety of smaller ones ■ rush to manufacture. In the case of pallets after these tests, however, it was found that the durability was reduced and that the assembly of many individual parts again resulted in costs.

The purpose of the present invention is to make a pallet

several plastic molded parts, which are not too big supposed to keep them in not too elaborate thorns with smaller ones Machines can be manufactured to create soft pieces that are particularly easy to assemble.

The invention consists in that on the upper side of the foot body brackets and on the underside of the hat counter clearamers are integrally molded or openings for the brackets to reach through are formed in the plates and that on the upper side of the foot body as well as on sawtooth-like projections are provided on the underside of the plates. Such brackets and Gerrenklamrnern, which connect the foot body with the plates after assembly by simply pushing together, can be elongated in cross-section slat-shaped structures, but also T-groove guides, groove and spring connections with preferably wedge-shaped grooves and wedge-shaped springs, advantageously in several in a line at ^;.; orc ^: neten specimens.

A pallet according to the invention can be made up of, for example, identically shaped, elongated foot bodies assemble two plastic plates. The plates can also be shaped in the same way, so that the individual parts get relatively cheap. Through the provided. Klamme] * · and Counter-clamp elements, the five individual parts mentioned can be easily pushed together to form a pallet, with the sawtooth-like projections interlock and thus give the five parts such a hold with one another, that the parts can no longer be separated from each other. It is very easily possible to match this palette with these particular ones To design features in such a way that pushing the parts together is very easy.

The sawtooth-like protrusions are formed appropriately so that _L ied :: r has a sawtooth Lanee and a short plank. The lance planks of the counter saw teeth move over the long flanks when the plates are pushed onto the foot body. After being pushed on, the short planks of the saw teeth and the counter-saw teeth lie against each other and give the parts of the pallet an excellent hold.

Now you can put the brackets and the sawtooth surfaces in arrange in different ways. If you only have one Shape for the body of the foot and a single j? Orm for the lulls wants to use in the production, it is useful if the plank arrangement anywhere on the plates in the points in the same direction, i.e. if the flanks are all arranged in the same direction; are. In this case they are Saw zahnf lan.cen aui "opposite one half of the foot body to the plank direction; on the other half of the To arrange the foot body. In this version, the Place the two plates on the foot body with a distance and then move them towards the middle of the foot body.

For easier pushing together these parts are between Leave gaps between two neighboring brackets that are slightly longer than the brackets. When assembling will da.Ji each plate only a short distance from theirs End position placed on the foot body and on this with the application of force - thus the resistance of the sawtooth-like Projections is overcome - shifted by the length of a bracket.

Another version according to the invention is designed in such a way that da5 c ... c -Arrezähne ευ: ne: i Puss bodies a re-directed : · Ί: ..:> ensr.crznunr aufweiser, and that £ the saw teeth on aer one, rlatte an opposite arrangement to the saw blade. the other plastic, zdne further execution is designed in such a way that the joggers on the feet once -! calibrated "" have a plunic arrangement that the Sare teeth to the p ^ attrr. ir. area of the outer ^ uiiBody have the same .. order, but ii. Area of rr ? ufikörpers on one plate an opposite one Arrangement to the saw teeth of the middle area of the other Has plate. In this embodiment, the two slats of a pallet are not completely shaped in the same way , but they can be on the same form after substitution or rotation by 180 ° of those strips in the j'orm are made that the shaping of the sawtooth-like 7ors? Rims serve, for assembly is done with these Pallets a little different: First the panels are placed close to each other, then the foot bodies are pushed into one execution from different sides, in the other execution from the same side.

iiun ". for reasons of better otability, the Make puss bodies hollow, possibly with special pusses are formed, between which openings remain, into which the stacking tools of stacking machines can reach. J ^ s is useful when the foot surfaces of the foot body dovetail-shaped recesses for those to be inserted Have crossbars.

The essence of the present invention is based on a in the drawing achem-itically illustrated execution boisrieles as well as a modification of this embodiment

The pallet of Fig. 1 consists of two integrally molded Plastic plates 1, under which the foot body 2 is arranged are, which are made of plastic in one piece and which are at the same time the connection of these two plates 1 serve * Feet 3 are formed on them. These feet have dovetail-shaped recesses 4- on their foot surface on, through which slats of trapezoidal cross-section for transverse reinforcement can be pushed. The foot bodies point on their top brackets 5 in the form of after Jeiten directed projections, which behind Gegenkla. mern 6 in the form of elongated, hook-shaped structures in cross-section, which are attached to the underside of the plates 1 are arranged and are preferably made in one piece with the plates. While the brackets have length A as well v: ie have the Gegenklaanern 6 is between the Clamps 5 and the counter clamps 6 a free space of length 3 -.- elasjen, where length B is greater than the length A. These brackets and counter brackets can be in different - / can be realized. In the drawing, a very simple embodiment is shown: the brackets 5 at the top of the foot body protrude laterally from the foot body. There are simple ledges on how to make them knows as springs in a tongue and groove connection of wooden boards, for example. These projections 5 engage in counter brackets 6 a, as a cross-section hook-shaped or U-shaped structure on the "underside of the plates 1 on these are integrally formed. Due to the hook shape of the counter-plaintiffs 6 a groove is created between these and the plates, into which the projections 5 acting as brackets are inserted so that ultimately a hat-spring connection is created

Area of before jumps 5 sawtooth-like Areas 7 are provided, which in FIGS. 10 and 11 are shown in greater detail. : .an het the area of Projections ρ chosen because here the surface of the foot body 2, insofar as it is based on the plates 1, is particularly large is. Correspondingly, sawtooth fields β in FIGS. 4 and shown, which are attached to the underside of the plate 1. In F; .g. 4 is only part of the width of these fields 8 too see, because through the hook-shaped counter-clamp 6 a part is covered. In FIG. 6, however, it can be seen how the sawtooth field 8 is located under the counter bracket 5.

As can be seen from Fig. 12, the assembly of the Pallet accomplished in that the three foot bodies are arranged parallel to each other, the two plates are placed on top and then printed against each other according to the direction of the arrow. So that the two plates 1 now meet exactly in the i; middle of the Pu.:body 2 is it is advantageous if the rods 9 »fit into the gorge Projections 5 are inserted, have a wedge-shaped cross section. Then it is achieved that a too far insertion with certainty will vern_Leden. For this each projection 5 is advantageously also wedge-shaped, as shown in FIG.

The projections 25 acting as brackets can also be seen, including the opposing clear surfaces 26. The plate 21 is supported with the hook-shaped opposing clamps 25 on brackets 42 arranged on the foot body 22 below the bracket-like projections 25. Hips 43 on the underside of the plate 21 grip between the walls 44 of the foot body <° 2 and provide additional centering and additional support. It can also be seen here how the foot bodies 22 are designed in the form of a roof in the area of the openings 50 on the upper side of their lower spar. The interaction of the sawtooth surfaces 2? and 28 can be seen from FIGS. 18, 19 and 20. Here, too, a plane laid through the sawtooth surface does not run completely parallel to the surface of the plates, but at an acute angle, so that wedge shapes are created for the projections 25 and the grooves. Cross-slats 24 made of plastic can be seen in section in their special dovetail-shaped design in FIG. 18. These are also designed in the shape of a roof in areas between the feet 25. Holes 42 are provided for securing the parts together. In Fig. 19 it can be seen how the two plates 21 butt against one another in the middle of the pallet. These plates 21 each have a downwardly directed tongue 45 on their left edge, on the right edge a sprue 46 with an upwardly directed groove 47. Tongues 45 and groove 47 of two adjacent plates 21 engage in a tongue and groove connection together and are gripped under by the rib 48 of the middle foot.
