Definitions
- the invention relates to a pallet made of plastic according to the preamble of claim 1.
- pallets are available on the market that are made either from wood or from plastic, in particular by injection molding.
- the advantage of the wooden pallet is a certain degree of robustness and low manufacturing costs, but wooden pallets are increasingly being replaced by plastic pallets, especially for the transport and storage of high-quality goods.
- plastic pallets are now very robust and are usually designed for very long operating and use times of 10 years and beyond, and plastic pallets are far less dirty in use because they are quick and thorough in a simple manner compared to wooden pallets can be cleaned.
- the pallets are available in different standard sizes, in particular in sizes of 800 ⁇ 1200 mm, 800 ⁇ 1000 mm, to name just a few standard sizes by way of example.
- pallets are often used, which are referred to as half pallets and, purely for example, have standard dimensions of 800 ⁇ 600 mm.
- These half pallets are particularly suitable as a supplement to the standard pallets with dimensions of 800 ⁇ 1200 mm.
- the pallets usually have in common are designed with runners on the underside, through which the pallet stands on the surface.
- three runners are used for pallets in the usual standard dimensions, which are arranged parallel to one another and at a distance from one another as well as parallel to a pallet edge.
- the two outer runners are on two opposite edges of the pallet and the third runner is in the middle of the pallet Pallet arranged.
- the adjacent skids on the underside of the cover plate of the pallet define access openings between them, which facilitate transport using conventional lifting devices. These access openings are used so that the tines of forklifts or pallet trucks can be inserted under the cover plate of the pallet between the runners and the pallet can thereby be raised for transport and placed again at the desired storage location by lowering it.
- the runners are each arranged via support feet at a distance from the cover plate, with three support feet usually being used per runner. These support feet also form engagement openings between them for the insertion of tines of forklifts or similar lifting devices, so that the pallet can also be gripped and transported on the narrow side of lifting devices. In this respect, it is usually possible to pick up the pallet using conventional lifting devices by engaging tines from all sides of the pallet.
- the problem with transporting loaded pallets using motor-operated lifting devices or manually operated hand pallet trucks is that the tines often hit the skids when the lifting devices are retracted under the pallet or under the upper deck of the pallet, depending on the force or frequency of the impact or impact can lead to damage to the skid area of the pallets.
- This problem occurs particularly in pallets with reduced standard dimensions, i.e. in particular in half pallets with standard sizes of 800 x 600 mm, for example. Due to the width of the two tines of the lifting devices, there is only little room for the thickness of the outer support feet on the pallet edges. This means that the smaller the standard size of the pallet, the less space or thickness is available for the outer support feet, which must be flush with the edges of the pallet on the outside.
- the outer support feet have to be made comparatively thin or thin-walled, which entails an increased risk of damage to the runners, i.e. the lower part of the pallet including the support feet, in these areas brings.
- wooden pallets for example, are either fitted with metal profiles on the outer surfaces or are made entirely of metal profiles, which is not the case with plastic pallets.
- ends of the support skids of plastic pallets with the outer support feet arranged thereon form weak points with a not insignificant risk of breakage if lifting devices are operated carelessly. This has led to plastic pallets in these areas often being made from hollow profiles with internal reinforcements, However, if a shock is initiated, this can ultimately lead to damage to the upper deck.
- Pallets made of plastic are known in the prior art, in which runners can be connected to the cover plate of the pallet via plug-in extensions and can be releasably attached using locking elements, so that if a runner is damaged, it can be completely replaced ( DE 10 2014 219 398 A1 ). Furthermore, it is known (EP 2 722 285 A1 ), to provide pallets with rod-shaped stiffening elements in the skid area. For this purpose, the stiffening elements are inserted into recesses in the runner and fastened via lateral stabilizing elements in plate form, which can be inserted into recesses in the runner. The attachment is done via locking hooks, so that the stiffening elements of the runners can be replaced if they wear out.
- pallets with linear skid elements are known in the prior art ( EP 1 354 807 A2 , DE 10 2008 0478 56 A1 , WO 01/76 9 60 A1 ), whereby the skid elements are connected to the pallet support feet.
- ES 1 071 497 are known plastic pallets that are equipped with runners. The connection of the runners to the cover plate takes place via the support feet of the runners.
- the object of the invention is to create a simply constructed pallet that enables quick and easy replacement in the event of damage to the pallet. According to a further aspect, damage to the remaining pallet parts, in particular the upper deck, should be avoided in the event of impact loads, in particular when retracting the tines of lifting devices.
- the several, usually three, runners below the cover plate of the pallet are each divided into several runner elements, preferably each runner into two separate runner elements, which then form the runner in the mounted position on the pallet.
- Each skid of the pallet is specially equipped, namely in that the skid as such has support foot-like angled end sections at its two ends, which form skid support members, which, together with further support feet on the underside of the cover plate of the pallet, keep the skids at a distance from the underside of the cover plate and between or between themselves and the support feet on the underside of the cover plate of the pallet, limit corresponding engagement openings for the engagement of tines of conventional lifting devices.
- the angled skid support members provided at the ends of each skid take on the function of conventional support feet on the underside of the cover plate of the pallet.
- the skid support members are formed at the ends of the skid base of the skid, on the underside of which the pallet rests on the ground after being parked by the lifting device.
- the runner is divided into separate runner elements, in particular into a pair of runner elements, i.e. the runner is divided into two runner elements.
- the subdivision or division expediently takes place in the area of the runner base, with two runner elements in particular being formed in the case of a central runner division. In the assembled position, these complement each other, possibly including the underside of a support foot of the pallet, to form a continuous skid base.
- the skid is releasably connected to the cover plate via the skid support members, the free end of each skid element, which lies opposite the corresponding skid support member, expediently being releasably connected to a support foot of the cover plate. If damage occurs in a skid area, for example due to careless handling of lifting devices, then it is not the entire skid that needs to be replaced, but rather only the damaged part of the skid in the form of a separate skid element.
- the skid is divided transversely to the skid base into at least two, but preferably two, skid elements, each skid element being L-shaped according to the invention, and the L-legs through the skid support members and the L-web through the corresponding skid base Skid element is formed.
- the fact that the skid support members are expediently designed identically to one another results in a flush design of the skid base, in particular its underside, after the skid elements have been installed.
- the skid elements each forming a skid can be releasably connected to the cover plate via their skid support members by a positive plug-in connection and/or, if necessary, a latching connection be.
- a combination of a positive plug-in connection and a snap-in clip is also more useful, which enables quick disassembly/assembly.
- a latching lock can be provided, via which the skid element can be releasably connected to a support foot at this end.
- this connection is preferably carried out using a separate mechanical fastening means. Quick-release screw bolts with a quick-release thread or, in particular, bolts with a bayonet lock are suitable for this.
- the usually radially wider bolt head is accommodated in a recess in the cover plate flush with the surface of the cover plate and the bayonet lock or screw lock of the bolt interacts with the skid base surface for the purpose of locking.
- a reverse design is also possible, i.e. anchoring the bolt head from the underside of the skid base with recessing in the skid base and fixing the bolt in the area of the cover plate. Both variants are useful.
- the ends of the skid elements opposite the skid support member which lie against one another in the assembled position to form the skid, have height-offset, mutually complementary and in particular annular receiving flanges for the fastening means are provided.
- the ends of the skid elements engage with one another in the assembled position, that is, the receiving flanges of the two skid elements are arranged one above the other, so that both skid elements can be anchored or fastened to the cover plate using one and the same fastening means.
- each skid element is positively connected to the cover plate via the support members, the skid element expediently being held via a shoulder part spanning a recess for engagement with the skid support member, in which the skid support member is preferably held only by a plug-in, in particular positive-locking, connection. A mechanical fixation of the skid element can then take place at the other end using a mechanical fastening means.
- each skid element opposite the skid support members it is also expedient for the ends of each skid element opposite the skid support members to be connected and fastened separately to the cover plate via a fastening means independently of one another on a support foot.
- a fastening means independently of one another on a support foot.
- skid support members can be fitted in a form-fitting manner into a complementary recess on the cover plate.
- a clip-like snap lock can also expediently be provided, although this is not mandatory.
- the pallets are provided with three support feet for each skid area, with two of the support feet being formed by the skid support members in accordance with the invention.
- the ends of the skid elements opposite the skid support members are each fastened to the support foot arranged in the center of the cover plate expediently via a mechanical fastening means.
- each L-shaped skid element is placed obliquely on the underside of the cover plate and then pivoted downwards, so that the clip-like locking or the positive fit of the skid support members on the cover plate takes place and then the skid elements can be swung away in the direction of the cover plate the locking takes place via the mechanical fasteners.
- the skid elements are stiffened.
- a fiber-reinforced plastic material is suitable for this, for example by incorporating carbon or glass fibers, or by embedding rigid stiffening elements, for example in the form of steel inserts or the like.
- the cover plate with the particularly centrally arranged support feet as well as the separate skid elements are each produced in one piece from plastic by injection molding.
- pallet used herein and in the claims is to be understood very broadly in the sense of the invention and refers to a load carrier, which in a preferred case is formed only from a pallet with a flat cover plate without side walls, but also a load carrier in which the pallet is integrated as a lower part and thus as part of a large load carrier or large container.
- a load carrier to form such a large container, side walls extend upwards from the cover plate, which then forms the bottom part of this container, and are arranged all around.
- This can be a rigid, i.e.
- a hinged lid can optionally be provided in at least one side wall, or the side walls are hinged directly to the cover plate or to frame members arranged thereon via hinges and the like.
- the term “pallet” includes such load carriers that are intended in particular to hold lumpy goods.
- the pallet as a load carrier forms the base part or the substructure of a large container, also called a large load carrier, with which the load carrier stands on the floor, such containers being used in particular to hold lumpy goods.
- large containers also known as large load carriers or large containers, are constructed like containers and have standard length and width dimensions of approximately 800 mm x 600 mm upwards and often have pallet dimensions in the base area.
- the pallet according to the invention then forms, so to speak, the load carrier due to an additional wall structure, with the cover plate of the pallet forming the bottom part of the large container or large container.
- Fig. 1 shows an embodiment of the pallet according to the invention in a view from above, the pallet 1 having a cover plate 2 with a flat contact surface which is used for the transport of goods and goods.
- the pallet 1 further comprises three runners 4, here of identical design to one another, which are arranged parallel to one another and parallel to a side edge and therefore parallel to the two opposite side edges 6 due to the rectangular floor plan.
- the side edges 6 are the edges of the narrow side of the pallet.
- the pallet has in particular three support feet 8 arranged centrally, that is to say along a central longitudinal axis of the pallet, through which the distance between the lower part of the runners 4 and the pallet ceiling, that is to say the cover plate 2 of the pallet 1, is fixed.
- the Skid 4 has at its two opposite ends each a right-angled skid support member 10, which is designed like a support foot and is arranged in a row on the longitudinal edges 9 of the pallet 1 at a distance from one another.
- These skid support members 10 also determine the distance of the lower part of the skid 4 from the underside of the cover plate 2 of the pallet 1. How clear Fig.
- the runner 4 has an elongated, strip-like runner base 12, which has an in Fig. 2 Due to the incorrect representation, it has an upper underside with which the pallet normally rests on the surface in the correct rotational orientation.
- the underside is not assigned a reference number here.
- Each skid 4 is advantageously divided into two skid elements 4a and 4b in the middle of the skid base along a transverse separation plane 14, as best shown Fig. 3 emerges.
- Each of these skid elements is constructed in an L-shape, namely from half the length of the skid base and the angled skid support member 10.
- a projection 15 At the free end of the skid support member 10 there is a projection 15, which can preferably be fitted in a form-fitting manner into a complementary recess 16 on the underside of the cover plate 2 expediently, but not necessarily, releasably attachable by a suitable, in particular clip-like, locking connection.
- each skid element can be placed obliquely on the underside of the cover plate so that the projections 15 can engage in the corresponding recesses 16.
- Each skid is then pivoted in the direction of the corresponding middle support foot 8 and expediently engages there with its skid base in a corresponding complementary recess 18 in the middle support foot 8.
- the latching lug formed by the projection 15 automatically snaps into a corresponding latching pattern on the underside the cover plate in the area of the recess 16, so that the free end of each skid support member 10 can be locked with the underside of the cover plate 2.
- flange-like annular recesses 20a and 20b which are offset in height from one another, lie coaxially on top of one another, so that an overall flush underside of the skid base surface 12 of each skid 4 results (cf. Fig. 4 , front runner).
- a bolt 22 is suitable as a fastening means and is provided with a bayonet lock 24, shown here as bayonet thread sections.
- the bolt 22 has a radially expanded bolt head at the other end.
- bayonet bolts are known and do not need to be described in more detail.
- the bayonet bolt 22 is inserted from the underside, although a reverse arrangement is also useful in that the bolt can be inserted into a corresponding receptacle from the top of the cover plate 2 and then the bayonet mimic on the bolt with a corresponding bayonet mimic, for example in the ring flange 20b of the Skid element works together, which in the in Fig. 3 shown representation from above rests coaxially on the annular receiving flange 20a.
- both skid elements are releasably locked to the upper deck via a bolt, here in the area of the middle support foot.
- a skid element if a skid element is damaged, it can be quickly and easily replaced with an undamaged new skid element. All you have to do is open the bayonet lock, take out the bolt and then move the corresponding skid element upwards as shown in Fig. 3 be swiveled up so that the free end of the skid support member can also be unlocked from the upper deck and the damaged skid element can be removed and replaced with a new one.
- the projection 15 with the latching mechanism is designed in such a way that it can be fitted flush into the recess 16 on the underside of the cover plate and is therefore flush with the outside and the underside of the cover plate. This is very clear Fig. 1 .
- Fig. 4 shows a further embodiment of the invention, in which each of the L-shaped skid elements 4a, 4b is connected to the central support foot of the cover plate 2 separately by a mechanical fastening means, here again expediently by a corresponding bayonet locking bolt, as shown in Fig. 3 is shown, can be releasably locked.
- the positive and/or locking connection of the skid support members corresponds to that of the embodiment according to Figures 1 to 3 , so it doesn't need to be described again here.
- the other components also correspond to those of the previously described embodiment. How Fig.
- Fig. 5 shows a detailed view of an attachment of the ends of the skid elements 4a, 4b to the cover plate 2 of the pallet 1, purely by way of example using the embodiment according to Figures 1 to 3 , although the out Fig. 5 illustrated attachment of the ends of the skid elements also in other embodiments, in particular the embodiment according to Fig. 4 is equally applicable.
- the skid elements 4a, 4b are provided at their outer ends, namely at the ends of the angled skid support members 10, with an outwardly directed projection 15, which is designed as an outwardly projecting tongue and, in the exemplary embodiment shown, preferably extends parallel to the skid base surface of the skid elements.
- the projection 15 is part of a flange part 24 formed on the inside of the skid support member 10, which is L-shaped.
- the projection 15 cooperates with a recess 16 in the cover plate 2, into which it can be inserted.
- the recess and projection 15 are designed to be complementary, so that a positive connection results. This undercuts how clear it is Fig.
- the projection 15 is a shoulder part 26 provided on the recess 16.
- the shoulder part 26 bridges the recess 16, but can also be formed on the side surfaces of the walls of the recess in the form of an extension or in the form of projecting stubs.
- the shoulder part 26 prevents the skid element, here the skid element 4b, which is finally fastened via the fastening element in the middle pallet area, from moving out of the recess; rather, the skid element is fixed as a skid in the functional position and positively caught within the recess 16, so that only at the opposite end, i.e.
- Fig. 6 shows the use of the pallet 1 as a bottom part of a large container 28, the side walls 30 of the large container being connected to the corresponding sides of the cover plate 2 and thus the pallet, so to speak, in a preferably foldable manner.
- the special design of the pallet with the interchangeable skid elements can also be used analogously for large containers.
- These large containers are well known and have a pallet-shaped bottom part on which the side walls 30 are arranged, usually foldable.
- the side walls are preferably arranged on frame members 31 of the base part designed as a pallet 1 and are in particular hinged in a foldable manner.
- the frame members 31 are preferably arranged around the pallet.
- the frame members 31 are part of the pallet, but this is not mandatory. They could also be connected separately to the bottom part of the pallet 1 by a snap-in or plug-in connection, but protrude upwards from the bottom part at the edge. From the base part to the upper edge of the side walls 30, the height of such large containers is in the range of 80 to 110 cm, so that a large-volume storage space is possible for holding particularly lumpy goods. These large containers have pallet-like standard dimensions.
- Fig. 7 shows the large container with the bottom up so that the runners 4 can be seen.
- the bottom part of the pallet 1 corresponds to the exemplary embodiment Figures 1 to 3 , whereby also a pallet according to the embodiment Fig. 4 is applicable.
- the bottom part of the large container forms, so to speak, the pallet 1 with the lower part in the form of skids, so that the Figures 1 to 4
- the pallet shown can be inserted and used as a base part of a large container.
- Fig. 6 and 7 As can be seen, in this exemplary embodiment the large container is only equipped with two runners 4, but this is only an example. If necessary, depending on the size of the large container, a medium skid can also be used as in the embodiments according to Figures 1 to 4 be provided.
