The plastic pallet for transport and storage of goods comprises hollow profiles (1) and transversely oriented foot elements (2) which are joined to one another by means of connector pieces (3). An Independent claim is also included for a pallet system comprising at least two plastic pallets which are axially joined to one another by at least one elongate, preferably metal connector profile introduced into one of the hollow profiles.

Description

The invention relates to a plastic pallet and the plastic pallet comprising Pallet systems. The plastic pallet and the pallet systems are used for transport and / or the storage of goods, preferably of winding rolls. To winding rolls End-to-end products are wound, for example sheets made of metal, paper or plastic. The invention is particularly preferably used for Plastic film roll.

It is common to use wooden pallets, for example in the form of euro pallets. However, the material wood causes a hygiene problem because it is damp Environment and especially after wet cleaning tends to mold. in the Injection molded plastic pallets, as they are also known, have material-related hygiene problem does not arise. The injection molding pallet production is however not flexible with regard to the manufacturability of different pallet sizes. In addition, the injection molded pallets are only as stable as with great effort the wooden pallets can be produced.

It is therefore an object of the invention to provide a pallet which can be used in different sizes is easy to manufacture and inexpensive and none Hygiene problems caused.

Another task is to create a pallet system with which Winding rolls can be transported and / or stored easily and gently can.  

A plastic pallet according to the invention comprises at least two hollow profiles Plastic and at least two plastic foot elements. The hollow profiles and the Foot elements are connected to each other by means of a joint. The hollow profiles extend across the foot elements. Although an arrangement of the hollow profiles perpendicular to the foot elements is preferred, should also with the term "transverse" such arrangements can be included in which the hollow profiles and the foot elements cross over other than at right angles. Although not essential, so it is strongly preferred that the hollow profiles point parallel to each other. Prefers will also be a parallel arrangement of the foot elements. Preferably each is the Hollow profiles connected to each of the foot elements by means of a joint connection. A particularly simple and preferred range consists exclusively of hollow profiles and Foot elements, each connected in pairs by means of a joint connection are. The hollow profiles preferably form a support surface for a support arrangement stores the goods hanging; if necessary, an insensitive good can also simply be opened the hollow profiles are stored.

A hygienic palette is obtained through the use of plastic, which, in particular, can easily be cleaned wet, for example with steam. By moving away from injection molded pallets and manufacturing the structure instead Joining and connecting individually manufactured, simpler plastic parts are the same get several benefits. In particular, the hollow profiles can be easily Endlessly manufactured by extrusion, but flexibly cut to any desired length become. The pallet length measured in the direction of the straight hollow profiles can therefore can be easily adapted to user needs. There are also hollow profiles with the same weight more rigid than simple full profiles, for example Rectangular sections. Compared to rigid special profiles, such as double T Profiles, if they have price advantages, are easier to clean torsionally stiff and do not offer any protruding edges that could break off. On Hollow profile with a closed jacket is preferred.  

The hollow profiles are preferably extrusion profiles. Although the foot elements of Extrusion profiles can be formed, the foot elements are preferred Injection molded parts. It can be made with a few, different sized injection molds for the Foot elements also have sufficient flexibility in terms of a variation in Longitude of the foot elements measured width of the pallet can be obtained. Since the Injection mold for a foot element is significantly cheaper than the injection mold for a whole range, the cost is even in the case of desired width variations significantly lower than with the injection molded pallets. The manufacture 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 use, for example by forming indentations on the top of the foot elements to accommodate the hollow profiles and / or indentations on the underside of the Foot elements for forming one or more exemptions per foot element, which improves stability; in particular can on the foot elements Feet are formed. Instead of injection molding, the foot elements can be advantageous can also be made by other methods using a mold, for example by compression molding and optionally subsequent sintering.

The joint between a 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 Base element is polypropylene, not least because of its good weldability. The hollow profiles can advantageously be formed from a plastic regenerate, in particular the polypropylene mentioned. This applies to the foot elements Likewise.

The use of hollow profiles provides another particular advantage that two or more pallets according to the invention in a very simple manner in the axial direction their hollow profiles can be put together by face-to-face in two facing, preferably abutting, hollow profiles a common  Additional profile is introduced, the two hollow profiles and in the inserted state so that the two pallets are also preferably form-fitting and also frictional combines. The additional profile used as a connecting profile reinforces the two in this way joined hollow profiles additionally, especially with regard to bending stiffness. A particularly long connection profile can of course also do more than two Connect pallets together. Instead of a connection profile, such a Additional profile basically also as a pure reinforcement profile for a single hollow profile a pallet can be used. Of course, several hollow profiles can also be used a pallet are reinforced in this way. This way, one becomes general sufficiently stable and light pallet created, which if necessary for transport and / or the storage of particularly heavy goods is increased.

The plastic pallet according to the invention preferably forms a basic element of a Pallet systems, in preferred versions for goods to be stored such as especially winding rolls.

In a preferred embodiment, a pallet system has in addition to that Plastic pallet as a further element at least two plate-shaped supporting parts for the goods to be transported and / or stored. The at least two supporting parts are with the plastic pallet connected or connectable in such a way that it is in the connected state from the pallet to form supports for the goods, in particular one Can be winding roll. At least one of the support parts has a receptacle, the one Bearing point for the good forms and up to an edge of the at least one support part extends. The supporting part is accordingly towards the receptacle on the relevant edge open, so that a journal for the goods hanging on a crane, for example can be easily inserted into the admission up to an admission reason. The Recording is preferably open to an upper edge of the support member to the good easy to insert from above. However, the recording may also change instead open to a side edge of the support part for easy insertion of the Side.  

At least one of the support parts is preferably at least on its lower edge provided two guides, the same distance from each other and preferably also an adapted, particularly preferably the same shape as the at least two Have hollow profiles in the plastic pallet. If the palette has more than two next to each other arranged hollow profiles, the number of guides preferably corresponds at least the number of hollow profiles. The guides improve in preferred Execute the state of the support parts on the hollow profiles by taking their bearing surface enlarge. Furthermore, they secure the supporting parts against slipping sideways at least in one, preferably in both directions across the hollow profiles. One too Guidance is advantageous, the two or more hollow profiles preferably with a certain Grips clamping force.

One or more of the guides can be from one to the other lower edge of the support part open recess, d. H. from an indentation, be formed. It is also advantageous to form one or more guides Guides each through a hole, such a hole being both a through hole and can be a blind hole. In a further, likewise preferred embodiment, a guiding element protruding from the underside of the supporting part, preferably a rigid one Guide element or an elastic, but still sufficiently stiff snap, such a tour.

A guide preferably has a shape such that it is a hollow profile or several hollow profiles positively or more preferably at least positively and frictionally partially encompasses. If the guide is formed by an indentation, this can The supporting part can simply be placed on the hollow profiles from above. After touchdown the supporting part is preferably clamped onto the hollow profiles by means of its guide or clamped. With a circular outer cross section, for example, the hollow profiles can the indentation has a corresponding semicircular shape and advantageously with front semicircular edges with a certain clamping force inwards against the respective Press the hollow profile. In a likewise preferred embodiment, at least one engages behind front area of such an indentation, preferably both reach behind the front  Areas of an indentation, a largest cross section of a hollow profile, so that a Snap connection between the relevant support part and the hollow profile in question is formed. In this embodiment, at least one indentation, preferably several indentations, also an additional tilt protection for the receive relevant support part.

The supporting parts are preferably also made of plastic. It can act in particular to plastic plates in sandwich construction, the advantages of Sandwich construction, namely great mechanical stability with low weight, but can also be obtained with other materials. If the supporting parts are out Plastic are produced, it is preferably 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 significantly should be over 10 cm. A thickness between 4 and 8 cm is preferred. The supporting parts should be thick enough to stand free on the hollow profiles can.

The support parts with the feature of the open receptacle and / or the at least one Guide at the bottom are particularly advantageous in connection with the plastic pallets according to the invention. However, you can also use other pallets form an advantageous pallet system. 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 leadership alone and especially in combination with the open admission has advantages as long as it forms a support for the supporting part Support profiles of a pallet such an outer contour and in such an arrangement exist that by means of a guide or preferably several guides the seat of the supporting part in question is improved on the supporting profiles. The applicant retains it is therefore one or more supporting parts with an open receptacle and / or at least a guide that improves the seat, also in combination with other pallets in one or to claim multiple divisional applications, for example in connection with  Wooden pallets, one-piece plastic pallets and pallets with inclusion metallic materials.

The plastic pallet according to the invention can also be a pallet system with supporting parts and form bearing sleeves. The bearing sleeves are with the good, preferably one Winding roll, connectable in such a way that its bearing points in the receptacles of the Form support parts. The supporting parts are preferably the above described supporting parts, although this is not absolutely necessary.

According to a first aspect of the invention, at least one of at least two Bearing sleeves of the pallet system on a slot that extends over the entire length of the Bearing sleeve extends and is so wide that a transport rod or more generally a support rod for the goods can be inserted through the slot in the bearing sleeve. In other words, the bearing sleeve can pass through its slot on the Transport rod are pushed on radially 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 are pushed on so that they form the bearing point in one of the transport rod can be inserted through the opening of the goods. The Accordingly, the bearing sleeve has a free inner cross section, so that the Bearing sleeve surrounding the transport rod can be moved along the transport rod can. The bearing sleeve preferably has an outer cross section such that it is in the opening of the goods is received with a tight fit.

A longitudinally slotted bearing sleeve has the advantage that the bearing sleeve on the Transport rod can be pushed on while the goods on the transport rod hanging from a production machine with the help of a crane, for example and transported to a pallet.

The invention further relates to a pallet system with at least one according to the invention Plastic pallet, 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; this is fundamentally necessary However not. So that the double flange has the desired advantage of a fixation in the longitudinal direction of the bearing sleeve, one with the bearing sleeve cooperating support member have a receptacle that allows the bearing sleeve can be placed in the receptacle so that the supporting part between the two Double flange forming flanges of the bearing sleeve engages and the two flanges form axial displacement locks. The flanges preferably point in the axial direction the bearing sleeve such a distance from each other that the support member between the both flanges is tightly bordered.

A longitudinally slotted bearing sleeve is just like a bearing sleeve with a double flange to form a storage location for a good to be transported and / or stored, in particular a winding roll, even without the plastic pallet according to the invention advantageous. In particular, a combination of a transport rod and are advantageous at least one longitudinally slotted bearing sleeve (transport rod bearing sleeve Combination) and a combination of at least one bearing sleeve with one Double flange and a support part (support part-bearing sleeve combination), which in particular can be designed according to the invention. The applicant reserves the right to do so longitudinally slotted bearing sleeve, the bearing sleeve with double flange and on the two mentioned combinations to submit one or more divisional applications.

The plastic pallet according to the invention also forms a preferred pallet system together with at least one base plate. The bottom plate has on its underside at least one guide to at least the base plate on the plastic pallet to guide one of the hollow profiles and to prevent them from slipping across the hollow profiles, at least with respect to a transverse direction. The leadership is preferred by at least one guide element protruding from the underside of the base plate formed that as an elastic, but still stiff snapper or only as a stiff Cross guide interacts with one of the hollow profiles. The leadership can in particular an elongated guide rail, or more preferably two elongated guide rails are formed. Will the leadership of at least  formed two guide elements, so preferably encompasses each of the at least two Guide elements that hollow profile with which it interacts, preferably by being close to the hollow profile in question. Furthermore, they encompass at least two guide elements, the hollow profiles preferably on their facing away from each other Outsides or on their mutually facing insides.

A pallet system according to the invention with at least one plastic pallet and at least one base plate is already for the transport and / or storage of goods standing freely on the base plate advantageous. If at least one Bottom plate forms a closed contact surface, any piece goods can be on it or even bulk goods are transported and / or stored. If necessary, the Base plate for this purpose to be developed into a box element. The Bottom plate, however, can also be used for the purpose of saving weight be closed plate, and also in this training with or several lateral borders or a peripheral border to be provided to prevent goods placed on the base plate from sliding down. Will be such a pallet system with a base plate around at least two side walls and one Protective hood added, so there is already a protective container for high-quality piece goods formed, for example for the transport and / or storage of vehicles, Pieces of furniture and much more. The side walls of the pallet system are also also still provided with the recordings according to the invention, the goods can in such a way formed protective containers can also be transported hanging and / or stored.

The applicant also reserves the right to register a division on a pallet system to direct that at least one base plate of the type described and at least one Has a pallet with a contact surface which interacts with the base plate in such a way that a guidance of the base plate is obtained as described. Such a pallet does not necessarily have to be made of plastic. It also does not have any hollow profiles have, and the connection of foot elements and corresponding profiles, which must also form a support surface for goods or for the supporting parts described not be connected by a joint. However, it is  Range of the system the more advantageous, the more it with the subject of claim 1 matches. This statement also applies to the other basic systems for build the purposes of this application on the pallet according to claim 1.

The invention is explained below on the basis of exemplary embodiments which are described in Figures are shown. Features that become apparent from the exemplary embodiments form individually and in each combination of characteristics including each of several Characteristic combination formed embodiments, d. H. a combination of one or more features of an embodiment with one or more Features of another embodiment, the subject of the claims advantageous further. Show it:

Fig. 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 comprises a pallet which consists of a layer of the same hollow profiles 1 and a layer of the same base elements 2 . The hollow profiles 1 are extrusion profiles, and the foot elements 2 are injection molded parts. Both the hollow profiles 1 and the foot elements 2 can be formed from plastic regenerate, in particular from polypropylene. In the exemplary embodiment, two parallel hollow profiles 1 and three parallel parallel foot elements 2 , which extend exactly at a right angle to the hollow profiles 1 , form the plastic pallet.

The plastic pallet of Fig. 1 and 2 is shown separately also in Fig. 3. In order to facilitate the joining of the hollow profiles 1 and the foot elements 2 , an indentation 4 is formed on each of the foot elements 2 for each of the hollow profiles 1 . The hollow profiles 1 are partially accommodated in the indentations 4 . In the area of the indentations 4 , the hollow profiles 1 are welded to the foot elements 2 .

Each of the foot elements 2 is provided at its lower edge with an exemption which extends over most of its length, so that a base is obtained at each end of the foot elements 2 . The hollow profiles 1 protrude on the upper sides of the foot elements 2 beyond the foot elements 1 .

The hollow profiles 1 have a circular cylindrical outer cross section and a circular cylindrical inner cross section, ie they are simple, round tubes. In principle, the hollow profiles 1 can also have a different external cross-sectional shape and / or a different internal 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.

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

The pallet system further comprises two support parts 6 , each of which is formed by a plastic plate in a sandwich construction. The support parts 6 stand freely on the support profiles 1 . They each have a uniform plate thickness of 6 cm.

Fig. 5 shows three types of support parts 6 , which can form a pallet system with the plastic pallet and preferably other parts. The left support part 6 corresponds to the support part 6 of FIGS . 1 and 2. Each of the three support parts 6 forms a closed surface with the exception of a receptacle 7 or 8 and indentations 9 . The indentations 9 each form a guide for the supporting part 6 in question . The formation of the support parts 6 as wall-forming plate parts facilitates the formation of a protective container for the wound winding roll.

The protective function can be seen in particular at a glance from FIG. 2, which shows the transport and / or storage device of FIG. 1 with a protective hood 18 attached. The protective cover 18 forms with the support members 6 a closed except at the bottom protective container in which the winding roller 15 attached to two axial bearing sleeves. Of the two bearing sleeves are shown in Figs. 1 and 2 depending on an outer flange of a Doppelflansches to recognize 12th In Fig. 5 bearing sleeves are individually shown before an introduction into their respective receptacle 7 or 8 .

In the three alternative embodiments shown in FIG. 5, a supporting part 6 of the pallet system has two indentations 9 on its underside. The recesses 9 are adapted to the shape according to the outer cross section of the hollow profiles 1, ie, in the exemplary embodiment the recesses 9 are circular segment shaped. Due to the adapted shape of the indentations 9 , the supporting parts 6 lie flat on the hollow profiles 1 . This improves the state of the free-standing support parts 6 placed on the hollow profiles 1 .

The indentations 9 advantageously also form a clamping device at the same time in order to clamp the otherwise free-standing support parts 6 with the plastic pallet. This is achieved by a corresponding shaping of the indentations 9 in that the supporting parts 6 with a certain tension in the cross-sectional center lines press on the outer edge regions of the recesses 9 of the hollow profiles 1 against the hollow sections. 1

Below the left support part 6 , two exemplary embodiments for indentations are shown in FIG. 5 and are designated by the reference numerals 9 and 10 . The indentations 9 are semicircular as in the supporting parts 6 shown . The indentations 10 shown as alternative embodiments have outer edge regions which are extended towards one another in the shape of a lip. In this way, indentations 10 are created on the undersides of supporting parts designed in this way, which engage behind the hollow profiles 1 over a cross-sectional center line. The lip-shaped protruding edge areas of the indentations 10 form elastic snaps and at the same time prevent tipping of the supporting parts provided with such indentations 10 .

Instead of forming the guide through several separate indentations, the two indentations 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 alternatives supporting part of Fig. 5 differ from each other in respect to the respectively formed receptacle 7 and 8 respectively. The central support part 6 is designed in a conventional manner with respect to its receptacle 8 . The receptacle 8 is formed by a round hole in the support part 6 .

However, the two support parts 6 shown on the outside have receptacles 7 which are designed as slots which are open on one side, ie the receptacles 7 are open towards an upper edge of the support parts 6 . Furthermore, they are funnel-shaped, that is, they taper towards a reception reason. The respective receiving base of the receptacles 7 is again rounded, in the exemplary embodiments semicircular, in order to offer the largest possible bearing surface to the correspondingly shaped bearing sleeves. The left support part 6 differs from the right support part 6 only in the number of receptacles 7 . While the left support part 6 has a single receptacle 7 , the right support part 6 has two. With a pallet according to FIG. 1 or FIG. 2 and two support parts 6 according to the right support part 6 of FIG. 5, a transport and / or storage device for two winding rollers 15 suspended next to one another can be formed. As indicated in Fig. 5, a support member 6 can be designed with two receptacles 7 with a lower height than the left support member 6 , in this case to serve as a support member for two winding rollers 15 with a smaller diameter.

Two alternative embodiments are further illustrated for the bearing sleeve of the pallet system in Fig. 5. The bearing sleeve shown in connection with the middle support part 6 corresponds to the prior art. It is formed by an annular cylindrical sleeve body 11 with a single annular flange 12 'at one end. In connection with the two outer supporting parts 6 , preferred bearing sleeves are shown, each having the same sleeve body 11 as the known bearing sleeve, but each having a double flange 12 at one end of the respective sleeve body 11 . The double flange 12 is formed by two parallel spaced washers. A clear axial distance between the two ring disks is slightly larger than a thickness which the supporting parts 6 cooperating therewith have in the area of their respective receptacle 7 , at least in the area of the respective receptacle base. In the exemplary embodiment in which the support plates 6 are each formed by plate parts of uniform thickness, this naturally means that the clear distance between the ring flanges 12 is slightly thicker than the thickness of the relevant support parts 6 . The clear distance between the flanges is chosen with respect to the relevant thickness of the support parts 6 so that the bearing sleeve comes to lie in the receiving base of the receptacle 7 so that on the one hand the sleeve body 11 lies flat in the receiving base and on the other hand the respective support part 6 between the two flanges of the double flange 12 is closely bordered. In this way, an axial securing effective in both directions is obtained by the double flange 12 , as can be seen from FIGS . 1 and 2. At the same time, the supporting parts are thereby stabilized by means of the winding roller 15 .

Fig. 6 shows in an uppermost of four representations the bearing sleeve of Figs. 1, 2 and 5. Fig. 6 also shows in three representations a particularly preferred embodiment of a bearing sleeve, once in a single representation, then in combination with a transport rod 17 and finally in combination with the transport rod 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 which extends over the entire length of the bearing sleeve, and in particular also through the double flange 12 .

Plastic webs, in particular foils, are usually wound onto a winding tube 16 , as shown only by way of example in the bottom illustration in FIG. 6. The winding roll 15 of FIG. 1 is wound on such a winding tube 16 . Transport rods 17 , like the simple round rod of FIG. 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 FIGS. 1 and 2. This is usually done with a crane system, for example a ceiling crane. In a first step, the transport rod 10 is passed through the winding tube 16 while the winding roller 15 is still in the winding position. In a subsequent next step, the winding roll is suspended from the winding stand, hanging on the transport rod 17, by means of the crane system and transported to a certain point, preferably up to the exact point via the transport and / or storage device of FIG. 1. In this position, be in a next step both sides of the winding roller 15, but slid between the formed on both sides of the winding reel 15 suspension points of the crane system each have a bearing sleeve with an axial slot 13 radially on the feed bar 17 and then pushed into the winding tube 16 in the axial direction of the feed bar 17th The two of the winding roll 15 facing, inner annular flanges of the double flanges 12 of the two bearing sleeves, up to abutment against the mandrel 16 or the mandrel are pushed 15th Now the winding roll 15 can still be lowered hanging from the crane, so that the two double flanges 12 of the bearing sleeves move into the receptacles 7 of the supporting parts 6 up to the receiving base and the double flanges 12 have been pushed over the supporting parts 6 on both sides , Only then, ie after reaching the position shown in FIG. 1, is the connection to the crane system released and the transport rod 17 pulled out of the winding tube 16 . A particular advantage of the axial slot 13 is thus the simplification of the handling of the winding roller 15 , since the bearing sleeve having the axial slot 13 is pushed onto the transport rod 17 in the radial direction between the winding roller 15 and a one-sided suspension point, but subsequently along the transport rod 17 into the winding tube 16 or in general in the winding roll 15 or any other good having an appropriate opening can be introduced.

In Fig. 7 the formation of a double pallet 20 is shown, which may be necessary to accommodate winding rolls, the width of which exceeds the length of a single pallet measured in the axial direction of the hollow profiles 1 . In order to obtain flexibility in this regard, the pallet system comprises connecting profiles 14 which are adapted to their cross-sectional shape according to the inner cross section of the hollow profiles 1 , so that they can be inserted into the hollow profiles 1 . The shape is such that an easy-to-produce plug connection is created between each connecting profile 14 and two hollow profiles 1 pushed over it. The outer contour of such a connecting profile 14 preferably corresponds to the inner contour of the hollow profiles 1 , so that an easily releasable positive and frictional connection between a connecting profile 14 and two hollow profiles 1 is obtained after insertion or sliding over. In principle, however, the connecting profile 14 can only be loosely received in the hollow profiles 1 if two bearing sleeves with a double flange 12 are used, since these can also hold the pallets axially to one another via the supporting parts 6 . The connecting profiles 14 can also be plastic profiles, in particular hollow plastic profiles. In order to further improve a reinforcing effect, the connecting profiles 14 can also be formed as full or preferably hollow metal profiles.

Fig. 8 shows the plastic pallet comprising two side parts 21, which no indentations on their undersides for the purpose of guiding the hollow profiles 1, but close to its respective lower, smooth edge, two through holes 22 may have. Each of the through holes 22 has the shape of the hollow profiles 1 with a slight oversize in cross section. The through holes 22 are recessed close to the lower edge of the side part 21 at a distance corresponding to the distance between the hollow profiles 1 in the plate surface of the side part 21 . The side part 21 is pushed from the side onto the plastic pallet, ie onto its hollow profiles 1 , as indicated by the dash-dotted lines and an arrow in the example of the left side part 21 . Although the side part 21 forms a closed surface with the exception of the holes 22 , the side part 21 can of course also be provided with a receptacle 8 or, preferably, one or more receptacles 7 which are open to one side. 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.

FIG. 9 finally shows a pallet system which has 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 as basic elements. The second basic element can not only be formed as a one-piece base plate 24 per plastic pallet, but instead or in addition to it, also in several pieces, from a plurality of base plates 25 , which only form the entire base plate arranged next to one another, as shown at the bottom left in FIG . The bottom plate 24 - and also each of the bottom plates 25 - has on its underside two guide rails 26 which are shaped and arranged on the underside in such a way that they form rigid, lateral guides along which the bottom 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 the 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. In order to obtain an additional anti-tipping device, the guide rails 26 encompass the hollow profiles 1 over their respective largest cross section. The pushed-on base plate 24 or 25 can therefore no longer tip off from one of the hollow profiles 1 after being pushed on.

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

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

The pallet system shown in FIG. 9 can in particular be supplemented by the supporting parts 22 and the protective hood 18 , as are shown by way of example in FIGS. 2 and 8, in order to obtain a closed protective container for, for example, motorcycles, bicycles or other piece goods. The length of the base plate 24 or the plurality of base plates 25 , which together form the support or set-up surface, is of course chosen in this combination such that the two side parts 21 can also be pushed onto the hollow profiles. Of course, the base plate 24 or the plurality of base plates 25 can also be used advantageously in connection with the supporting parts 6 and possibly also with the protective hood 18 , in order to enable the hanging storage of goods, for example winding rolls, as described and at the same time one for these goods to have a protective bottom plate. The base plate 24 or the plurality of base plates 25 are provided with corresponding recesses in the case of use in combination with support parts 6 which have indentations 9 or 10 or projecting guide elements.

A longitudinal section through one of the leg members 2 is the top left in Fig. 9 as an example of a preferred, stable, lightweight construction for the foot members 2.
