The hollow internal space (2) of exter-nal walls being ribbed by partition walls (3) running perpendicularly to the main plane (10) of the pallet (1). At least in corner area the partition walls (3) are arranged as corner partition walls (13) so that loading and impacts whose directions also exhibit components in the direction of the main plane (10) and are directed towards the corner area of the pallet (1), are dissipated and distributed by means of the corner partition walls (13) to areas of the pallet (1) lying behind them. Alternatively an elastic design bending location relative to the remainder of the pallet is formed in the supporting part (4) around the corner area.

Description

The invention relates to a pallet which is commonly used for storing and hence for transporting goods together with the pallet and can be moved, for example, by forklifts or stackers.

BACKGROUND OF THE INVENTION

Such pallets may consist of different materials. However, when transporting products that are sensitive to hygiene, such as fresh food, especially fresh meat, there is a problem that the hygiene pallets used for these products, in addition to the basic requirement of sufficient stability under the required products, must meet a wide range other requirements.

On the one hand, the pallet must be made of a material whose surface can be easily cleaned of impurities, in particular of germs, and into which the surface of such germs is very difficult to penetrate. In principle, a metal, in particular a light metal or plastic, is suitable for the purpose of the material selection, and plastic, in particular moldings, the entire interior of which is hollow and ribbed, is cost-effective.

A further requirement is that such pallets must be so resistant to mechanical loads that they must be able to withstand a drop test in which the pallet falls from a certain height on a corner without breaking, and in a subsequent leak test in which the pallet inflates with compressed air at positive pressure.

Until now, this requirement has been met only by the rib structure having such a strong spring action that the pallets have been able to withstand the test without damage or destruction.

The disadvantage, however, was that, in order to provide sufficient flexibility of the rib structure, it was necessary that these vertically extending ribs on at least one side, i.e. on the underside or on the top, were not rigidly reinforced by the top or bottom end plates.

Due to the open structure of at least the top or bottom of such sanitary pallets, deep cut-outs with sharp edges have been created which, as a result, are difficult to clean and impurities and therefore pathogens can settle.

SUMMARY OF THE INVENTION

The object of the present invention is therefore to provide a hygienic pallet which, in spite of solid outer surfaces on all sides and sufficient stability, is so flexible that it will withstand the respective pallet corner and overpressure test and make such a pallet as easy as before and cost-effective.

This task is solved by the features of claims 1 and 12. Preferred embodiments are evident from the subclaims.

As a rule, pallets are of such a construction that the legs arranged below the support part, which can be connected at the lower end to individual crops by means of running parts, are at least in the corners or even on the outer edge of the pallet.

In order for the pallet to pass the corner drop test, ribbing through the lamella walls or corners of the corner lamella walls is required so that the impact on the pallet in the corner passing in the direction of the main plane of the pallet or at least in the directional components of this main plane is walls in the corner portion of the inwardly lying corner lamella walls in the corner zone, the corner lamella walls and / or outer walls being designed to absorb at least one part of the impact energy by their elastic deformation and possibly to transfer excess impact energy into zones which they lie further around the corners.

The fact that the sector behind them, with increasing depth, widens from a rectangular corner, immediately leads to a drastic drop in the individual forces or their peak values.

Such an effect is achieved, for example, in that the corner zone, which is generally represented by the foot, has in the corner zone one or more, relatively spaced, curved corner lamellas which interconnect the outer walls bordering the corner and inwardly curving inwards to the center of the pallet.

Further from the corner there are also corner lamella walls which are mounted at the rear inside and which are also arcuate and arranged so that their external curvature points towards the corner, i.e. outwards. These inner corner lamella walls are reinforced by normal lamella walls which extend in a rectangular grid parallel to the outer edges, from which in the corner zone there is always formed one corner chamber in which the corner lamella walls are located.

These inner and outer, in each case one or more, curved corner lamella walls serve, on the one hand, to stabilize the boundary walls, in particular the outer walls in which the corner chambers are exposed and which, on the other hand, also serve as initial and an end point for at least one further corner lamella wall which extends transversely from the corner radially opposite the center of the pallet and which is additionally bent and therefore serves as a spring element, i.e. a spring between the arched corner lamella walls.

Corner slats extending from the corner inwards may start either on one outside of the curved corner slats or on the outer wall itself and end on one of the curved corner slats lying inside or on one of the normal slats passing through parallel to the outer edge of the pallet which delimits the corner chamber.

In addition, one or both of the outer walls in the corner zone, i.e. in the corner chamber zone that otherwise pass straight, may also have at least one hat-shaped or s-shaped curvature, with the hat-shaped curvature directed largely inwards. This also contributes to the springing of the outer wall in the direction of its main plane. Such curvature may also have radial corner lamella walls.

Wall thicknesses, curvature, radiuses of passage and the like, as well as materials such as unstretched polyethylene, must be aligned to achieve the required flexibility and elimination ability.

All the lamella walls and / or corner lamella walls and / or the outer walls are rigid, but are mainly in one piece and connected to each other, as is customary in the production of such a ribbed part, such as a plastic molding, or they lie at least closely next to each boundary wall.

In spite of the ribbing described above, the formation of solid, i.e. compact, external surfaces in all spatial directions, even against the inside of the fork tine apertures of the forklift, is achieved by assembling the pallet together from several individual parts with ribbed treads open on one side , which can advantageously be made as a plastic molding and glued or thermally welded using thermoplastic plastics or other known processes are adhesively bonded to one another.

The individual parts themselves may have through holes or tiled openings on one side, provided that the individual parts are brought together so that all the integral outer surfaces of these individual parts represent exclusively the outer surfaces of the finished pallet.

If we look sideways and hence in the direction of the main plane, then the palette consists mainly of:

- one central part which, on the one hand, includes a supporting part extending over the entire pallet base, as well as legs protruding downwards from the supporting part, which are located mainly in corner zones and which at their lower end may be connected to the running members , as well as

- one cover plate which, in appearance, also corresponds to the base of the pallet and which is fitted to the carrier as a top closure and

- base plates which correspond to the base plates and are fitted on their underside.

When fitting, care must be taken to ensure a compact connection to prevent dirt and germs from penetrating inside the pallet.

The central part has a compact, compact outer surface on the underside of its support part, as well as on all outer walls and on the peripheral walls, except for the upper side of the support part and the underside of the running parts or individual legs, so that the cover plate and the running boards compact, compact outer part.

The cover plate and / or the base plates have ribs which extend from their top end plate (for the cover plate) or from the bottom end plate (for the base plates) to the center piece, which is identical to the center piece ribs In this way, not only the outer walls but also the individual lamella walls forming the ribs are firmly connected to one another during insertion and gluing or thermal welding, as a result of which the strength of the pallet is considerably increased.

However, the previously described corner lamella walls are, in particular, on their lower and lower walls. also, or additionally, at their lower end, partially does not engage the cover plate or the cover plate, respectively. the base plate and its ribs, but ending spaced or behind, but loosely opposite the plate.

For this purpose, the cover plate itself must not have any ribbing itself in the corner chamber zone, and the corner slats project above the upper edge of the other central part so high that they end immediately on or below the lower edge of the upper end plate on the cover plate. The same also applies to the lower end of the corner slats opposite to the base plates, respectively. if the individual legs are not connected to each other in the chutes, the same applies to the end plates of the individual legs.

Likewise, the cover plate in the corner zone may also have ribs which, in whole or in part, coincide with the ribs lying on the underside of the corner zones of the central part.

The strength in the corner zone can be controlled by connecting the individual ribs in the corner zone between the center piece and the cover plate. If all the ribs in the corner zone are identical to each other in terms of their arrangement, welding must be avoided precisely during thermal welding, which is achieved by a sufficient height distance of those lamella walls which are not to be connected to each other.

In this way, the straight end plates of the cover plates or of the cover plates can be used. the base plate reduces the elasticity and spring action only to the desired extent.

Additionally, respectively. in addition to or instead of the mechanism described so far, a so-called " instead of the desired deflection, arcuate around the corner zone for easier removal of one of the corner zones from the other pallet as well as its resilient springing.

Instead of the desired deflection, it forms an arcuate groove which is incorporated into the support part in the central part and which extends substantially from one to the other outer edges of the pallet, which are reinforced by the respective corner. Also this cross-section of a little truncated groove forms a continuous, integral outer surface, which has no sharp internal corners, respectively. inner edges which could make it difficult to clean the outer surfaces of the pallet, which is of course five for all other inner edges of the pallet.

When viewed from the top of the central part inwardly of its support part, we can see that perpendicular groove lamella walls extend perpendicularly along the edges of the groove and a perpendicularly standing central groove wall extends along their center. While the grooved lamella walls are also rigidly connected to the cover plate or to the cover plate. by its ribbing, the groove-like central wall is adjacent only to the underside of the upper end plate, respectively. cover plates. Indeed, if the foot is cut off from the other part of the pallet along the groove, i.e. at the point of the desired deflection, the groove-like central wall is compressed upwards and supported on the top end plate, which consequently deforms upwards and at this bend it serves essentially as a spring element which causes a separate bending back to the initial position. This avoids the relative relative displacement of the bearing surfaces from the central part to the cover plate and at the same time a defined break is achieved.

A similar embodiment in the running parts which connect the individual legs to one another and which could also impede the corner zone in which the foot is located is generally not necessary, since the leg parts are made so hard and stable that there is no need to create additional location of the desired deflection.

A further possibility is that only the corner slats to be welded to each other are aligned in the same line in the cover plate and in the central part. Additional selection, eg. milling in the vertical direction of those corner slats to be welded to each other and hence variations in strength in the corner zone is no longer possible.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1 shows a variant of the pallet in the final embodiment, transversely from above and above. 2 shows the condition before joining the individual parts.

The basic design and especially the dimensions correspond to known pallets according to current standards.

As can be seen in Figures 2a and 2b, the pallet consists of one central panel 21, with a cover plate 8 mounted on its upper side and base plates 9a and 9b respectively mounted on its individual running parts. 9b.

In the middle part 21, one leg 5 projects out of the plate-shaped upper support part 4, the size of which corresponds to the base of the pallet 1, at each corner downwards and at the center of each of the outer edges. 1b, it is best to recognize that in the longitudinal direction of the pallet, each of the three legs 5 are connected to each other by one skid piece 6 into one skid 7.

As a result, each of the chutes 7 in the space between the three legs 5 has two holes for the prongs of the fork 25, e.g. of the forklift so that the pallet can be gripped in a known manner in the longitudinal direction, i. j. between the runners 7 as well as in the transverse direction by the forklift through the apertures of the fork tines 25, which in the individual runners 7 pass one behind the other.

The cover plate 8 with its outer contour coincides with the outer contour of the central part 21 and its upper end edge. The same also applies to the base plates 9a, 9b and to the base plates 6 which are associated therewith, so that after the cover plate 8 and the cover plate 8 have been correctly fitted. a fixed connection of the individual parts, e.g. by heat welding, which consist of a thermoplastic, for example polyethylene.

Due to the fact that the individual parts are at least identical in their outer structure and that the thermal welding is carried out around the entire circumference and possibly even along the internal ribs, a compact integral outer surface of the pallet 1 is produced.

In FIG. 2, it is best to see that the base plates 9a, 9b consist of a flat plate material without vertically projecting edge zones and without ribbing.

On the other hand, the cover plate 8 consists of one upper end plate 8 ', of which the outer walls 14a', 14b 'extend downwardly over the entire periphery of the end plate 8' and also in the inner zone there are a large number of lamella walls 3 'and 3'. corner slats 13 'which serve as ribbing and thereby strengthen the cover plate 8.

In addition, the cover plate 8 and hence its top end plate 8 'have on the top partly along the outer edges edge protrusions 22 intended to prevent slipping of goods loaded on the pallet 1 as well as partly in the central zone, almost along the longitudinal and transverse center axes. central protrusions 23 are provided to also prevent slipping of the load loaded on the pallet 1.

In order that the pallets 1 can be stacked on one another, the central projections 23 are arranged transversely only in such a way that, when the second pallet 1 is laid, they lie in the free space of the chutes 7. The central projections which are longitudinally engage into the central recesses 24 'of the intermediate chutes 7 of the pallet 1 which lies above it. For this purpose, the middle lower base plate 9b, which consists of only one lower end plate 9 ', has respective central slots 24 whose contour and position coincide with the central recess 24' on the intermediate base plate 6 of the intermediate part 21 lying above them. .

Fig. 3 shows a section through FIG. la resp. 4c along the line III-III, i.e. in the longitudinal direction of the pallet, along the outer chutes 7.

Here, it can be seen that at respective points to the normal lamella walls 3 of the central part 21, which - as can be seen from FIG. 2 - extend in the longitudinal and transverse directions, i.e. parallel to the outer edges 14a,

14b, the respective lamella walls 3 'in the cover plate 8 are located in the same place, so that when connecting the ribs of these parts, consisting of the intersecting lamella walls 3 and 3, respectively. 3 'are placed exactly one on top of the other and can be heat welded together. The same applies to the outer walls 14a, 14b and 14b respectively. 14a ', 14b'.

The contact plane 10 'between the cover plate 8 and the central part 21c is a horizontal plane, which therefore extends parallel to the main plane 10 of the pallet 1.

The detailed appearance of the pallet in its corner zones is apparent from FIG. 3 as well as a quarter of the central pallet part shown in FIG. 4a and 4b, respectively. a bottom view of the portion of the pallet shown in FIG. 4c.

FIG. 3, 4a, 4b, it is apparent that in the leg zone, the lamella walls 3 in the central part 21, which extend longitudinally and transversely, form passage chambers 19 open from top to bottom, while in other zones - i.e. the zone of the support part 4 between by the runners, as well as in the runner zone in the longitudinal sections in which the apertures for the tines of the fork 25 are located, the lamella walls 3 only project upwards or downwards from the integral outer surfaces.

The ribbing in the corner zone, which usually also has one of the legs 5, takes the following form:

The arrangement of the corner lamella walls 13 within the corner chamber 19 'is best recognized in FIG. 4c showing a bottom view of the central part:

In each corner zone, the outer walls 14a, 14b meet in the outer corner 26 as well as the normal lamella walls 3 and 3 respectively. 3a, which are opposed to and substantially extend rearwardly in parallel, form a corner chamber 19c in which corner lamella walls 13 are arranged having a different orientation than conventional lamella walls 3.

In the outer corner zone of the corner chamber 19 ', at the distance to the outer corner and at a distance therebetween, arcuate, approximately quadrant corner lamella walls 13a, 13b each extend from one outer wall 14a to the other outer wall 14b, the corner 26 forming the center of curvature of these corner the lamella walls 13a, 13b, which, by their external curvature, face inwards, i. j. against the center of the pallet.

In the inner corner situated opposite the diagonal and inside the corner chamber 19c there is an almost mirror-like, opposite, curved, approximately quarter-circular corner lamella wall 13c, which analogously extends from one lamella wall 3a to the other another lamella wall 3x, passing at right angles to the lamella wall 3a and bounding the corner chamber 19c.

The inner corner of the corner chamber 19 ', which is formed by the lamella walls 3a and 3x in this case again forms the center of curvature of the corner lamella wall 13c, so that it is directed by its external curvature against the corner 26 of the pallet 1.

By its size, this corner vane wall 13c corresponds to the larger, more inwardly extending outer corner vane walls 13b. The radius of the corner lamella walls 13b, 13c is almost as large as the width, i.e. the smaller section of the corner chamber 19 '. Both of these arched corner vane chambers 13b, 13c are connected radially to a corner vane wall 13d that is not straight but is somewhat arched and passes through the corner 26 of the pallet. While this corner vane wall 13d abuts almost at right angles to the outer curvature of the corner vane wall 13b, its outer volume gradually passes over the arched corner vane wall 13c.

Another radially extending corner slat wall

13e, which also bears at right angles to the outer volume of the quadrant corner vane wall 13b, and which is spaced from the radial corner vane wall 13d, gradually passes into the vane wall 3a, which at the same time represents one outer wall of the foot and thereby the corner chamber 19.

In addition, the longer outer wall 14b of the corner chamber 19 'has a helical bend 27 that extends inwardly of the corner chamber 19' and in the zone between the point of collision of the largest, outwardly extending arcuate corner walls 13b and the rear shoulder of the corner chamber 19 'extending from the corner 26 the outer wall 14b.

As can be seen from FIG. 3, the central part has a uniform height over its entire range, as well as all the lamella walls 3 and 3, respectively. the corner lamella walls 13 as well as the outer walls 14 have a continuous equal height.

Another possibility for the corner zone is that, as shown in FIG. 4a, 4b - the corner lamella walls 13, which are located in the corner chambers 19 ', protrude up over the remainder of the central part 21. As a result, no ribbing is required in the zone of the cover plate 8.

Irrespective of this, not all corner slats 13 or 13 will be supported. the corner lamella walls 13 will only be partially connected at their upper and / or lower end, in particular thermally welded to the cover plate 8 and / or the cover plate. base plate 9.

In the embodiment of FIG. 4c, only the inner quadrant corner lamella wall 13c and the largest outer quadrant corner lamella walls 13b are welded to the cover plate 8, which has a similarly arranged and shaped corner lamella wall 13c ', 13b', which is most obvious. 2b. In addition, in the cover plate 8 there is also a corner lamella wall 13a 'which coincides with the arched corner lamella wall 13a, but the corner lamella walls 13a and 13a' do not weld together. In thermal welding of the entire cover plate 8 to the entire central part 21, this is prevented by one of the corner slats 13a and 13a, respectively. 13a ' is shortened to a height so that it does not reach the contact plane 10 ' and hence the corresponding corner lamella wall.

As further seen in FIG. 2b, in the cover plate 8 there are no corner lamella walls similar to the corner lamella walls 13d, 13e. Instead, the slightly arched curved corner slats 13 'in the corner chamber of the cover plate 8 extend transversely to its longitudinal section, on either side of the hat-shaped bend 27' at the outer edge, facing each other outwardly curvature from the outer wall 14b 'to the slat wall 3a'. These corner lamella walls 13 'do not engage with the central part, in particular not with the other corner lamella walls 13d, e extending in a different direction.

The aforementioned shape will, on the one hand, relieve the loads and impacts on the corner 26 of the pallet 1 acting in or on the main plane and, on the other hand, allow them to be transported further to the pallet zones lying further inwardly. pallet damage. In addition, the upper end plate 8 is thereby stabilized against bulging under internal overpressure

An approximately similar effect is achieved by providing a desired groove 12 in the underside of the support member 4 on the central member 21 around each corner zone, typically around each leg 5.

The groove, as seen in Figures 4b and 4c, is formed somewhat arched around a corner 26, behind each one straight passing end piece, towards the respective outer edge 14a, 14b. On the narrow side of the pallet, the groove 12 terminates at about half the distance between the two skids 7. On the longitudinal side, the distance to the leg 5 is approximately half.

In the cross-section through the groove 12, we can see that this is an arcuate segment with an angle of less than 180 °, approximately 120 to 160 °.

As the support member 4 towards the edges becomes increasingly thicker, the groove in this edge zone becomes increasingly thicker and therefore does not immediately extend to the full edge 14a, 14b because the depth of the groove 12 is smaller, approximately half of the thickness. of the support part 4 on the central part 21, as best seen in FIG. Third

Looking at the central part 21 from the top side, the channel 12 acts as a bulge in the lower end plate of the support part on which the vertically projecting lamella walls 3 cross at a right angle and parallel to the outer edges 14a, 14b of the pallet. These lamella walls 3 are missing above the channel

12. Instead, these lamella walls 3 extend into groove lamella walls 17 which extend along one of the edges of the groove 12, also standing vertically and at the level of the other lamella walls 3, thus extending to the contact plane 10 '.

At approximately the same height, preferably in the transition zone between the arcuate part and the straight part of the groove 12, the grooved lamella walls 17 each have a section 18 which is curved in S-shape or in the form of a hat, as shown in FIG. 4c. At least on one of the trough-shaped lamella walls 17, as shown in FIG. 4a, e.g. on the outer of the two grooved lamella walls, there should be such a section.

In addition, the groove-like central wall 15 extends along the center line of the groove. This wall projects upwardly above the contact plane 10 '.

The cover plate 8 has a ribbing projecting downwards, including the flute-shaped slats 17 'and, as in the central panel 21, there is no ribbing from the normal slats 3' in the zone between the flute-shaped slats 17 '. a wall extending along the center of the channel so that the channel central wall 15 of the center panel 21 terminates just below the end plate 8 'of the cover plate 8.

If the corner zone is bent against the remainder of the pallet due to too much corner zone load, this estimation is made along the groove 12 (defined in Figure 3 as: downward corner of the right corner zone). As a result, this zone is further dispensed upwardly and the trough central wall 15 presses from below onto the end plate 8 '. Its stability, which is achieved by its own ribbing as well as by the connection with the central part, serves as a bending element which limits the bending and at the same time causes a separate back bending to the starting position.

The base piece 6 between the individual legs 5 is relatively weakly dimensioned and imparts only a very weak resistance to such bending.

As can be seen in FIG. 4a, the trough central wall 15 extends continuously in the form of a s-shaped or hat-like bend along the central line of the trough.
