Description

The invention relates to a plastic pallet and the plastic pallet system. The plastic pallet and the pallet systems are used for transport and / or storage of goods, preferably of winding rolls. Endlessly manufactured to winding rolls Products wrapped, for example sheets made of metal, paper or plastic. The invention is particularly preferably used for rolls of plastic film.

Common is the use of wooden pallets, for example in the form of Euro pallet. However, the material wood causes a hygiene problem because he in a damp environment and especially after wet cleaning tends to mold. Injection molded plastic pallets, as they are also known, have a material-related hygiene problem not on. However, the injection molding pallet production is not flexible in terms of the manufacturability of different pallet sizes. Also are the injection molding pallets only with great effort in the same stability as the Wooden pallets can be made.

Pallets made of metallic materials are used in the US 2,909,349 and the US 2,909,350 described.

The DE 91 13 312 U1 describes a support frame consisting of a base frame and at least one bearing block placed on it. The base frame is designed as a rectangular frame in the manner of pallets with longitudinal and cross struts placed one on top of the other.

From the DE 83 00 764 U1 a plastic pallet of tubular support struts and tubular main struts arranged transversely to them is known. The support struts and main struts are each formed as hollow, extruded plastic tubes. They are connected in pairs on the pallet by means of joint connections; connectors are called.

It is an object of the invention to create a palette that is easy in different sizes is producible and inexpensive, causes no hygiene problems and with regard to the respective use more optimal than the known ones Pallets can be designed.

Another task is the Creation of a pallet system, with the winding rolls on simple and can be transported and / or stored gently.

A plastic pallet according to the invention comprises at least two hollow profiles made of plastic and at least two foot elements made of plastic. The hollow profiles and the base elements are connected by means of a joint connected with each other. The hollow profiles extend across the Foot elements. Although an arrangement of the hollow profiles at right angles to the foot elements such arrangements are also to be preferred with the term “transverse” be included in which the hollow profiles and the foot elements themselves cross over other than at right angles. Although not inevitable required, it is highly preferred that the hollow profiles point parallel to each other. A parallel arrangement is also preferred of the foot elements. Each of the hollow profiles is preferably connected to each other by means of a joint connection each of the foot elements connected. There is a particularly simple and preferred palette exclusively from hollow profiles and foot elements, each in pairs by means of a joint connection are interconnected. The hollow profiles preferably form a bearing surface for one Support arrangement that hanging the goods layered; if necessary, an insensitive good can also be simple placed on the hollow profiles.

By using the material plastic will get a hygienic palette that is particularly easy wet, for example with steam, can be cleaned. Through the Moving away from injection molded pallets and manufacturing the structure instead by joining and connecting individually manufactured, simpler plastic parts will get several benefits at once. So the hollow profiles are on easily manufactured by extrusion endlessly and can be flexible to any desired Length can be cut to length. The pallet length measured in the direction of the straight hollow profiles can therefore particularly easy to adapt to user needs. Furthermore, hollow profiles with the same weight are more rigid than simple ones Vohprofile, for example rectangular profiles. Opposite to rigid Special profiles, such as double-T profiles, have price advantages, can be easier cleaned, are torsionally stiff and do not offer any protruding Edges that could break off. A hollow profile with a closed jacket is preferred.

The hollow profiles are extrusion profiles. The foot elements are injection molded parts or molded parts. Sufficient flexibility with regard to a variation in the width of the pallet measured in the longitudinal direction of the foot elements can also be obtained with a few injection molds of different sizes for the foot elements. Since the injection mold for a base element is significantly cheaper than the injection mold for a whole pallet, the costs are significantly lower than for the injection molded pallets, even in the case of the desired width variations. The production of the foot elements as separate injection molded parts has the advantage over extrusion that the shape of the foot elements can be optimally designed with regard to the use, for example by the formation of indentations on the top of the foot elements for receiving the hollow profiles and / or indentations on the Bottom of the foot elements for molding one or more exemptions per foot element, which improves stability. In particular, feet are formed on the foot elements. Instead of injection molding, the foot elements can also be produced by compression molding and, if necessary, subsequent sintering.

The joint connection between each hollow profile and a foot element is preferably a welded joint. An adhesive connection is also conceivable.

A preferred plastic material for the hollow profiles and preferably also for the foot elements is polypropylene, not least because of its good weldability. The hollow profiles can advantageously be formed from a plastic regenerate, in particular the above Polypropylene. In terms of of the foot elements this also applies.

Through the use of hollow profiles is given another special advantage that two or more pallets according to the invention can be joined together in a very simple manner in the axial direction of their hollow profiles can, in two mutually facing, preferably abutting, hollow profiles a common additional profile is introduced, which in the introduced state the two hollow profiles and thus preferably the two pallets positive and frictional connects with each other. The additional profile used as the connection profile reinforced the two put together like this Additional hollow profiles, especially with regard to bending stiffness. A particularly long connection profile can of course also connect more than two pallets together. Instead of as a connection profile can in principle also be such an additional profile as a pure reinforcement profile for a single hollow profile of a pallet can be used. Of course you can too several hollow profiles of a pallet are reinforced in this way. In this way becomes a generally stable and light pallet created, if necessary for the transport and / or storage of particularly heavy goods is increased.

The plastic pallet according to the invention forms preferably a basic element of a pallet system, in preferred versions for hanging too stored goods like especially winding rolls.

A pallet system points in one preferred execution additionally to the plastic pallet as a further element at least two plate-shaped supporting parts for that too goods to be transported and / or stored. The at least two Support parts are connected or connectable to the plastic pallet in such a way that they stick up from the pallet in the connected state to support the goods to form, which can in particular be a winding roll. At least one of the support parts has a receptacle that a bearing for the Well forms and up to an edge of the at least one support part extends. The supporting part is accordingly on the relevant edge open to the recording, so that a bearing pin for example hanging on a crane Well just be introduced into the admission up to an admission reason can. The receptacle is preferably to an upper edge of the support part open so that the goods can be easily inserted from above. The However, the shot can also become a side edge instead open the support part, for easy insertion from the side.

At least one of the supporting parts is at its lower edge preferably with at least two guides provided the same distance from each other and preferably also an adapted, particularly preferably the same shape as that have at least two hollow profiles of the plastic pallet. Know that Pallet more than two hollow profiles arranged side by side, so the number of tours corresponds preferably at least the number of hollow profiles. The guides improve in preferred execution the status of the supporting parts on the hollow profiles by increasing their contact area. Further at least secure the supporting parts against slipping sideways in one, preferably in both directions transverse to the hollow profiles. Even a single tour It is advantageous to use the two or more hollow profiles with a certain elasticity.

One or more tours can or can each from a recess open towards the lower edge of the supporting part, i.e. from an indentation. It is also advantageous the formation of a leadership or the several tours each through a hole, such a hole being both a through hole can also be a blind hole. In another, also preferred execution forms a guide element protruding from the underside of the supporting part, preferably a rigid guide element or an elastic, but still sufficiently stiff snapper, such a leadership.

A guide preferably has a shape such that it at least partially encompasses a hollow profile or a plurality of hollow profiles in a form-fitting manner or, more preferably, in a form-fitting and frictional manner. If the guide is formed by an indentation, the supporting part can simply be placed on the hollow profiles from above. After mounting, the supporting part is preferably clamped or clamped onto the hollow profiles by means of its guide. In the case of, for example, a circular outer cross section of the hollow profiles, the indentation can have a corresponding semicircular shape and advantageously press inwards against the respective hollow profile with a certain clamping force using front semicircular edges. In a likewise preferred embodiment, at least one front region of such an indentation engages behind, preferably both front regions of an indentation, a largest cross section of a hollow profile, so that a snap connection between the relevant support part and the part concerned fenden hollow profile is formed. In this embodiment, an additional anti-tilt device for the supporting part in question is also obtained by means of at least one indentation, preferably several indentations.

The supporting parts are preferably also made of Plastic formed. In particular, it can be plastic sheets act in sandwich construction, whereby the advantages of sandwich construction, namely large mechanical stability with low weight, but also obtained with other materials can be. If the supporting parts are made of plastic, it is preferred low-pressure injection molded parts, in particular also made of polypropylene. The supporting parts have a thickness that is not or at least not significantly less than 2 cm and not or at least not much about Should be 10 cm. A thickness between 4 and 8 cm is preferred. The support parts should be thick enough to hold them on the hollow profiles to be able to set up free-standing.

The supporting parts with the characteristic of open receptacle and / or the at least one guide at the bottom although particularly advantageous in connection with the plastic pallets according to the invention. You can but also an advantageous pallet system with other pallets form. So are the support parts with open receptacle or even several open receptacles per support part even in connection with wooden pallets advantageous. But also the leadership alone and especially in combination with the open admission brings advantages as long as the support profiles forming a support for the support part such a contour on a pallet and be in such an arrangement that by means of a guide or preferably several guides the seat of the relevant support part improved on the support profiles becomes. The applicant retains it is therefore one or more supporting parts with an open receptacle and / or at least one guide improving the seat also in connection with claim other pallets in one or more divisional applications, for example in connection with wooden pallets, formed in one piece Plastic pallets and pallets including metallic materials.

The plastic pallet according to the invention can also form a pallet system with supporting parts and bearing sleeves. The bearing sleeves are can be connected to the goods, preferably a winding roll, in such a way that they form the bearing points in the receptacles of the supporting parts. at the supporting parts are preferably the supporting parts described above, although this is not inevitable is required.

According to a first aspect of the invention at least one of at least two bearing sleeves of the pallet system one Slit on that over the entire length the bearing sleeve extends and is so wide that a transport bar or more generally said a support rod for the goods can be inserted through the slot into the bearing sleeve. With others Words it can be the bearing sleeve pushed radially through its slot onto the transport rod and does not have to, as with conventional bearing sleeves, from one end of the transport rod in the axial direction of the transport rod be postponed so that they form the depository in a inserted through the transport rod opening of the goods can be. The bearing sleeve accordingly has a free inner cross section, so that the bearing sleeve the Transport bar surrounding lengthways the transport bar can be moved. The bearing sleeve points preferably such an external cross-section, that they're in the opening of the property with a firm seat.

Has a longitudinally slotted bearing sleeve the advantage that the bearing sleeve can be pushed onto the transport rod while the Hanging well on the transport bar for example with the help of a crane from a production machine is taken and transported to a pallet.

The invention further relates to a Pallet system with at least one plastic pallet according to the invention, at least two supporting parts and at least two bearing sleeves, wherein at least one of the bearing sleeves has a double flange. The supporting parts can advantageously be designed according to the invention his; in principle however, this is not necessary. So that the double flange the wished Advantage of a fixation in the longitudinal direction bearing sleeve brings, must interact with the bearing sleeve Carrying part have a receptacle, which allows the bearing sleeve so in the recording can be placed that the supporting part between the engages both flanges of the bearing sleeve forming the double flange and the two flanges form axial displacement locks. Preferably the flanges have such a distance from one another in the axial direction of the bearing sleeve on that the support part between the two flanges is tightly edged becomes..

A longitudinally slotted bearing sleeve is just like a bearing sleeve with a double flange to form a bearing point for a goods to be transported and / or stored, in particular a winding roll, even without the plastic pallet according to the invention advantageous. A combination of is particularly advantageous a transport rod and at least one longitudinally slotted bearing sleeve (transport rod-bearing sleeve combination) and a combination of at least one bearing sleeve with a double flange and a support member (support member-bearing sleeve combination), which in particular trained according to the invention can be. The applicant retains it even on the slit Bearing sleeve, the bearing sleeve with double flange and one on the two combinations mentioned or to submit multiple divisional applications.

The plastic pallet according to the invention bil det also a preferred pallet system together with at least one base plate. The bottom plate has at least one guide on its underside, in order to guide the bottom plate on the plastic pallet on at least one of the hollow profiles and to prevent it from slipping transversely to the hollow profiles, at least with respect to a transverse direction. The guide is preferably formed by at least one guide element projecting from the underside of the base plate, which cooperates with one of the hollow profiles as an elastic, but nevertheless stiff catch or only as a rigid transverse guide. The guide can in particular be formed by an elongated guide rail or even more preferably by two elongated guide rails. If the guide is formed by at least two guide elements, each of the at least two guide elements preferably encompasses the hollow profile with which it cooperates, preferably by being in close contact with the relevant hollow profile. Furthermore, the at least two guide elements preferably grip around the hollow profiles on their mutually facing outer sides or on their mutually facing inner sides.

A pallet system according to the invention with at least a plastic pallet and at least one base plate is already for the Transport and / or storage of free standing on the base plate goods advantageous. If the at least one base plate is a closed one Contact surface forms, can any piece goods or even bulk goods transported and / or stored. If necessary, the base plate too be further developed into a box element for this purpose. The bottom plate can also be used as a non-closed plate for the purpose of saving weight be trained, and also in this training with one or more side edges or a peripheral edge, to put goods on the floor slipping down to prevent. Will such a pallet system with base plate at least two side walls and added a protective hood, a protective container for high-quality piece goods has already been formed, for example for the transport and / or storage of vehicles, Pieces of furniture and much more. Will the side walls of the pallet system also with the recordings according to the invention provided, so the goods in the protective container formed in this way also transported hanging and / or stored.

The applicant reserves it also plan to direct a divisional application to a pallet system, that at least one base plate of the type described and at least a pallet with a support surface has that cooperates with the base plate so that a guide of the Base plate is obtained as described. Such a pallet must not necessarily be made of plastic. You don't have to either Have hollow profiles, and the connection of foot elements and corresponding profiles, which is a support surface for goods or for the described support parts do not have to be in the way of a Retaining compound be connected. However, the range of the system the more advantageous they are with the subject of claim 1 matches. This statement also applies to the other basic systems that for the Build purposes of this application on the pallet according to claim 1.

The invention is described below of embodiments explains which are shown in figures. Which become apparent from the exemplary embodiments Features form individually and in each combination of features including each from several embodiments formed combination of features, i.e. a combination of one or more Features of an embodiment with one or more features of another embodiment, the subject of Expectations advantageous further.

1 shows a winding roll 15 , for example a wound plastic film which is suspended in a transport and / or storage device. The device is formed by a pallet system. The pallet system includes a pallet that consists of a layer of the same hollow profiles 1 and a layer of the same foot elements 2 consists. The hollow profiles 1 are extrusion profiles, and the foot elements 2 are injection molded parts. Both the hollow profiles 1 as well as the foot elements 2 can be formed from plastic regenerate, in particular from polypropylene. In the exemplary embodiment, two hollow profiles arranged parallel to one another form 1 and three parallel foot elements 2 which are exactly at right angles to the hollow profiles 1 extend the plastic pallet.

The plastic pallet of the 1 and 2 is also individually in 3 shown. To assemble the hollow profiles 1 and the foot elements 2 to he lighter, is on each of the foot elements 2 for each of the hollow profiles 1 one indentation each 4 educated. The hollow profiles 1 are in the indentations 4 partially recorded. In the area of the indentations 4 are the hollow profiles 1 with the foot elements 2 welded.

Each of the foot elements 2 is provided on its lower edge with an exemption that extends over most of its length, so that at both ends of the foot elements 2 one stand is obtained. The hollow profiles 1 stand on the tops of the foot elements 2 about the foot elements 1 out ahead.

The hollow profiles 1 have a circular cylindrical outer cross section and a circular cylindrical inner cross section, ie they are simple, round tubes. Basically, the hollow profiles 1 also have a different outer cross-sectional shape and / or a different inner cross-sectional shape. Although at least the outer cross-sectional shape is preferably round, it can also be formed by a polygon, for example a square. Basically the same applies to the internal cross section.

4 shows an advantageous development of the plastic pallet 3 , The range - the 4 arises from the range of 3 by fastening two runners 5 , on the undersides of the foot elements 2 , In the exemplary embodiment, the two runners 5 on the undersides of the feet of the foot elements 2 welded. The runners 5 are preferably made of the same material as the foot elements 2 educated. The range of 4 with the runners 5 is particularly suitable for high-bay storage.

The pallet system also includes two supporting parts 6 , which are each formed by a plastic plate in sandwich construction. The supporting parts 6 stand on the support profiles 1 free on. They each have a uniform plate thickness of 6 cm.

5 shows three types of supporting parts 6 that can form a pallet system with the plastic pallet and preferably other parts. The left support part 6 corresponds to the supporting part 6 the 1 and 2 , Each of the three supporting parts 6 forms a closed area with the exception of a recording 7 or 8 and indentations 9 , The dents 9 each form a guide for the supporting part in question 6 , The training of the supporting parts 6 As wall-forming plate parts, the formation of a protective container for the taken-up winding roll is facilitated.

The protective function is particularly important at a glance 2 out which the transport and / or storage device of 1 with an attached protective hood 18 shows. The protective hood 18 forms with the supporting parts 6 a protective container closed except on the underside, in which the winding roll 15 hangs on two axial bearing sleeves. Of the two bearing sleeves are in the 1 and 2 an outer flange of a double flange 12 to recognize. In 5 are bearing sleeves before being introduced into their respective receptacles 7 or 8th shown individually.

A supporting part 6 of the pallet system points in the three in 5 shown execution alternatives on its underside two indentations 9 on. The dents 9 are the shape of the outer cross section of the hollow profiles 1 adapted, ie in the exemplary embodiment the indentations 9 circular segment. Due to the adapted shape of the indentations 9 are the supporting parts 6 flat on the hollow profiles 1 on. This improves the status of the freestanding on the hollow profiles 1 attached support parts 6 ,

The dents 9 advantageously also form a tensioning device around the otherwise free-standing supporting parts 6 to brace with the plastic pallet. This is achieved by shaping the indentations accordingly 9 achieved by the supporting parts 6 on the outer edge areas of the indentations 9 with a certain tension in the area of the cross-sectional center lines of the hollow profiles 1 against the hollow profiles 1 to press.

Below the left support part 6 are in 5 two embodiments for indentations shown and with the reference numerals 9 and 10 designated. The dents 9 are semicircular as in the supporting parts shown 6 , The indentations shown as alternative designs 10 have outer edge areas which are extended towards one another in the shape of a lip. In this way, indentations become on the undersides of supporting parts designed in this way 10 created the the hollow profiles 1 reach behind a cross-sectional center line. The lip-like protruding edge areas of the indentations 10 form elastic snappers and at the same time anti-tipping devices with such indentations 10 provided support parts.

Instead of forming the guide through several separate indentations, the two indentations can 9 or the two indentations 10 can also be brought together to form a single long indentation, so that the hollow profiles are only partially encompassed by the two mutually facing side edges of such a long indentation.

The three supporting part alternatives of 5 differ from each other in terms of the recording formed 7 respectively. 8th , The middle support part 6 is in terms of his inclusion 8th trained in a conventional manner. The recording 8th is from a round hole in the support part 6 educated.

The two supporting parts shown on the outside 6 however show recordings 7 on, which are designed as one-sided open slots, ie the recordings 7 are to an upper edge of the supporting parts 6 open towards. Furthermore, they are funnel-shaped, that is, they taper towards a reception reason. The respective reason for the recording 7 is again rounded, semicircular in the exemplary embodiments mig, in order to offer the largest possible contact surface to the correspondingly shaped bearing sleeves. The left support part 6 differs from the right support part 6 just by the number of shots 7 , While the left support 6 a single shot 7 has, has the right support part 6 their two. With a palette after 1 or 2 and two supporting parts 6 according to the right supporting part 6 the 5 can be a transport and / or storage device for two winding rolls suspended next to each other 15 be formed. As in 5 indicated, can be a supporting part 6 with two shots 7 with a lower height than the left support part 6 be carried out in this case as a supporting part for two winding rolls 15 to serve with a smaller diameter.

In 5 Two alternative designs for the bearing sleeve of the pallet system are also shown. The related to the middle support part 6 Bearing sleeve shown corresponds to the prior art. It is made of a circular cylindrical sleeve body 11 with a single circular flange 12 ' formed at one end. In connection with the two outer supporting parts 6 Preferred bearing sleeves are shown, each of the same sleeve body 11 have as the known bearing sleeve, but at one end of the respective sleeve body 11 one double flange each 12 exhibit. The double flange 12 is formed by two parallel spaced washers. A clear axial distance between the two washers is slightly larger than a thickness, which the supporting parts interact with it 6 in the area of their respective recording 7 , at least in the area of the respective reason for admission. In the embodiment in which the support plates 6 ever formed by plate parts of uniform thickness, this of course means that the clear distance between the ring flanges 12 slightly thicker than the thickness of the supporting parts in question 6 is. The clear distance between the flanges is related to the relevant thickness of the supporting parts 6 chosen so that the bearing sleeve in the receiving base of the recording 7 comes to rest so that on the one hand the sleeve body 11 rests flatly in the receiving base and on the other hand the respective supporting part 6 between the two flanges of the double flange 12 is narrow. In this way, the double flange provides axial security in both directions 12 get like this from the 1 and 2 is recognizable. At the same time, the supporting parts are thereby by means of the winding roller 15 stabilized.

6 shows in a top of four representations the bearing sleeve of the 1 . 2 and 5 , 6 also shows in three representations a particularly preferred embodiment of a bearing sleeve, once in a single representation, then in a combination with a transport rod 17 and finally in combination with the transport bar 17 and a winding tube 16 , The bearing sleeve of this embodiment not only has the double flange 12 , but also an axial slot 13 on, which extends over the entire length of the bearing sleeve, and in particular through the double flange 12 extends through.

On a winding tube 16 as they are the bottom representation of the 6 shows only by way of example, plastic webs, in particular foils, are usually wound up. The winding roll 15 the 1 is on such a winding tube 16 wound. transport bars 17 how the simple round bar of the 6 , are used for the transport of such winding rolls 15 from a winding stand of a production machine to the transport and / or storage device of the 1 and 2 used.

This is usually done with a crane system, for example a ceiling crane. In a first step, the transport rod 10 through the winding tube 16 passed through while the winding roll 15 is still in the wrapping station. In a subsequent next step, the winding roll is attached to the transport bar 17 suspended from the winding stand by means of the crane system and up to a certain point, preferably up to exactly above the transport and / or storage device of the 1 , transported. In this position, the next step will be on both sides of the winding roll 15 , but between the two sides of the winding roll 15 suspension points of the crane system each formed a bearing sleeve with an axial slot 13 radially onto the transport rod 17 pushed and then in the axial direction of the transport rod 17 into the winding tube 16 pushed. The two of the winding roll 15 facing inner ring flanges of the double flanges 12 of the two bearing sleeves can be pushed against the winding sleeve 16 or the winding tube 15 be pushed. Now the winding roll can 15 still hanging down on the crane, so that the two double flanges 12 the bearing sleeves in the recordings 7 of the supporting parts 6 retract up to the receiving base and the double flanges 12 in each case on the support parts on both sides 6 have been pushed. Only after that, ie after reaching the 1 position shown, the connection to the crane system is released and the transport rod 17 from the winding tube 16 pulled out. A particular advantage of the axial slot 13 is thus the simplification of handling the winding roll 15 because the axial slot 13 bearing sleeve between the winding roll 15 and a one-sided suspension point on the transport bar 17 be pushed on in the radial direction, but then along the transport rod 17 into the winding tube 16 or more generally in the winding roll 15 or any other good with an appropriate opening can be introduced.

In 7 is the formation of a double pallet 20 shown what may be required to accommodate winding rolls, the width of which in the axial direction of the hollow profiles 1 measured length of a single Range exceeds. In order to maintain flexibility in this regard, the pallet system includes connection profiles 14 , their cross-sectional shape according to the inner cross section of the hollow profiles 1 are adjusted so that they fit into the hollow profiles 1 can be inserted. The shape is such that an easy-to-produce plug connection between each connection profile 14 and two hollow profiles pushed over it 1 arises. The outer contour preferably corresponds to such a connecting profile 14 the inner contour of the hollow profiles 1 , so that after insertion or sliding over, an easily releasable form and frictional connection between a connecting profile 14 and two hollow profiles 1 is obtained. Basically, the connection profile 14 however in the hollow profiles 1 also be loosely received if two bearing sleeves with a double flange 12 can be used as these also the pallets over the supporting parts 6 can hold together axially. The connection profiles 14 can also be plastic profiles, especially hollow plastic profiles. To improve a reinforcing effect, the connection profiles 14 also be formed as full or preferably hollow metal profiles.

8th shows the plastic pallet with two side parts 21 on their undersides for the purpose of guiding the hollow profiles 1 no indentations, but two through holes near their lower, smooth edges 22 exhibit. Each of the through holes 22 shows the shape of the hollow profiles in cross section with a slight oversize 1 on. The through holes 22 are near the bottom of the side panel 21 at a distance between the hollow profiles 1 corresponding distance in the plate surface of the side part 21 except. The side part 21 is pushed from the side onto the plastic pallet, ie onto its hollow profiles 1 , as in the example of the left side part 21 is indicated by means of dash-dotted lines and an arrow. Although the side part 21 except for the holes 22 the side part can of course also form a closed surface 21 with one shot 8th or more preferably one or more recordings open to one side 7 be provided. The holes 22 can also be combined into a single elongated hole, although the separate formation is preferred in order to obtain a plate surface which is closed to the underside. The side parts 21 can instead or in addition form support parts for a protective hood.

9 finally shows a pallet system that as basic elements at least one plastic pallet according to the invention and at least one base plate 24 with almost or exactly the length of the plastic pallet. The second basic element can not only be used as a one-piece base plate for each plastic pallet 24 , but instead or in addition to it also in several pieces of several base plates 25 are formed, which are only arranged side by side to form the entire base plate, as shown in the lower left in 9 is shown. The bottom plate 24 - and also every single one of the floor slabs 25 - Has two guide rails on its underside 26 which are shaped and arranged on the underside in such a way that they form rigid, lateral guides along which the base plate 24 or 25 along the hollow profiles 1 can be postponed. The guidance is as tight as possible, but should allow easy, manual pushing on. The guide rails 26 form on their mutually facing inner sides of guide jacket surfaces, the shape of which is adapted to the outer contour of the hollow profiles, ie the guide jacket surfaces are circular segment cylindrical surfaces in the exemplary embodiment. To get an additional anti-tip device, grip the guide rails 26 the hollow profiles 1 across their respective largest cross-section. The slid-on base plate 24 or 25 can therefore no longer be pushed on by one of the hollow profiles 1 tilt.

As in 9 at the bottom plate 24 and a single one of the floor slabs 25 indicated, the floor slabs 24 and 25 formed by two superimposed plate parts, the lower one has a weight-saving, stability-increasing honeycomb structure, and the upper one forms a closed cover plate. The floor slabs 24 and 25 are preferably also plastic sheets, particularly preferably from a plastic regenerate and more preferably from the same material as the plastic pallet. For example, two plate parts per base plate 24 and 25 are preferably mirror-welded together.

Guide elements protruding from the underside, such as the guide rails 26 they can form instead of indentations 9 or 10 or instead of the holes 22 also with the supporting or side parts 6 and 21 form the guides, preferably in this case as an elastic snap.

This in 9 Pallet system shown can in particular around the supporting parts 22 and the protective hood 18 are supplemented, as exemplified in the 2 and 8th are shown in order to obtain a closed protective container for, for example, motorcycles, bicycles or other general cargo. The length of the bottom plate 24 or the several base plates 25 , which together form the support surface, is of course chosen in this combination so that the two side parts 21 can also be pushed onto the hollow profiles. Of course, the base plate 24 or can the multiple floor slabs 25 also advantageous in connection with the supporting parts 6 and if necessary also with the protective hood 18 be used to enable the hanging storage of goods, such as winding rolls, as described and at the same time to have a protective base plate for these goods. The bottom plate 24 or the several base plates 25 are used in combination with supporting parts 6 who have favourited Indentations 9 or 10 or projecting leadership have elements, provided with corresponding recesses.
