Skid pallet

The invention relates to a skid pallet with an upper part and a lower part formed from skids.

Transport pallets are known in many variations. In addition to wooden pallets, there have long been one-piece or single-piece Plastic pallets made of half-shells, which are already provided with steel or other inserts for stiffening Material have been provided. In all cases, the aim is to make the pallets as load-bearing as possible, to make insensitive and cheap. The load-bearing capacity and strength is to be dimensioned in such a way that the various test conditions the DIN standards are met.

The invention is based on the task of a transport pallet to create, which is particularly stable and load-bearing compared to known skid pallets and does not require a great deal of effort, either in terms of material or manufacture.

To solve the problem, the invention is based on a skid pallet of the type mentioned and is characterized in that the upper part is a one-piece, reinforced cover plate made of press wood is formed, are attached to the plastic injection-molded runners.

In a known manner, compressed wood is one made of shredded lignocellulosic fibrous material and one thermosetting binder hot-pressed mixture.

The pressed wood cover plate contributes significantly to the overall stability which is also not affected by higher temperatures and continuous loads will. In addition, the surface is desirably non-slip and less sensitive to wear. In contrast, the plastic injection-molded runners ensure long-term durability even with rough handling and occurring load surges. They are insensitive when the pallets are placed on a damp place

130008/0142

or greasy surfaces and are easy to clean.

In addition to separate runners, for example three lengthways Runners running on a rectangular pallet can also be runners supplemented to form a window cross made of plastic can be used. Such a lower part can be assembled or also from one piece be injected.

Further developments of the invention are the subject of the subclaims.

In a further development of the invention it can be provided that the cover plate has a substantially on the top flat surface with grooves pressed in and stiffening beads corresponding to the grooves on the underside owns. This not only allows a significant improvement in stability and Achieve load-bearing capacity without increasing the cost of materials, but also the channels can after Another recommendation of the invention is a water drainage system with at least one drainage point in the Form skid area. Rainwater or liquids that leak if the vessels break then run quickly and in a controlled manner.

To save weight and increase strength, the runners are recommended by Invention of two outer and at least one middle, Foot formed from a hollow body, which is connected at the bottom by a ribbed plate The feet arranged in the edge area and especially in the corner area of the pallet are advantageous Pulled up on the cover plate as edge protection. The one against hard knocks on the edges This means that the laminated wood cover is effectively protected.

To increase the overall stability and in particular To improve the flexural rigidity, there is the possibility in a further development of the invention that A reinforcing rod, in particular a steel rod, with a rectangular cross-section in the bottom of the runners is stored and attached to the cover plate together with the feet.

The invention is described below using an exemplary embodiment described in connection with the drawings. Show it:

FIG. 1 shows a plan view of a rectangular three-skid pallet according to the invention;

130008 / 0U2

FIG. 2 is a side view, cut in the left part, of the pallet according to FIG. 1 in the direction of the Broad side of an outer runner;

FIG. 3 in the left the top view and in the right part the bottom view of an outer runner for the pallet according to Figure 1 and Figure 2;

FIG. 4 shows a partial section of the cover plate according to the section line IV-IV in FIG. 1;

FIG. 5 is a partial sectional view of the connection between the cover plate and the foot of a runner;

FIG. 6 shows a sectional view of the runner according to FIGS. 2 and 3 according to the section line VI-VI in FIG if the cover plate is omitted.

The three-skid pallet shown in the drawings as an embodiment of the invention has a cover plate made of pressed wood in one piece. Below the plate 1 are three made of plastic Injection-molded runners, namely two outer runners 2 and a central runner 3 attached, which are in Figure 1 are only shown in dashed lines and will be described in more detail below.

On the top of the plate 1, recessed channels 4 form a water drainage system. The slope of the gutters

130008 / 0U2

and thus the direction of flow is indicated by arrows 5. The lowest point of the gutter system is located at the corners of the pallet. There short channels 6 lead to the outside, so that collected in the grooves 4 Water or other liquids may and may not run down in the area of the pallet corners Drip onto a possibly loaded pallet underneath.

FIG. 4 shows the cross section of the plate 1 in the edge area corresponding to the section line IV-IV in FIG 1. The grooves correspond to beads 7 on the underside of the plate 1, so that a total of through the Profiling results in a stiffening without additional material costs. According to the distribution of the channels the profiling in the other areas of the plate is similar. Do not necessarily have to corresponding beads are assigned to the gutters, rather gutters and beads can also be independent be arranged from each other.

The surface of the panel 1 made of compressed wood desirably has a certain roughness, which prevents the placed goods from sliding off too easily, even if they have a smooth underside. For the base of the grooves 4, however, the I _n teresse good flow properties is a smoother

130008 / 0U2

Surface desired. This can be done in the production of the plate 1 by a stronger compression in Reach the area of the gutters 4. In the case of higher demands on the surface quality of the pallets, in per se is known to take place in the form of co-pressed films made of melamine resin, with one optionally desired roughening can be carried out by sandblasting.

The structure of an outer runner 2 and its connection with the plate 1 is more precisely in FIGS. 2, 3 and 5, 6 ″ shown. The middle runner 3 is designed quite similar apart from its greater width, so that a more precise representation is unnecessary.

The runner 2 is injection-molded in one piece from plastic, for example from polyethylene or polypropylene or similar material. It has two outer feet 8 and a middle foot 9, which correspond to the cut Representation in the left part of Figure 2 are formed by hollow bodies. In the center of the rectangular or square (middle runner 3) shaped feet 8,9 are held by cut-out webs 10, tubular Arranged support column 11 through which, as Figure 5 shows in more detail, a lock screw 12 for fastening the plate 1 leads to the runner 2. The cover plate has a storage point for receiving the screw head 13 on. Instead of a carriage screw 12

130008/0142

can also use a tubular rivet (not shown) as a connecting element Find use.

The profiling of the cover plate 1 has not been shown in FIG. 2 for the sake of simplicity.

The feet 8, 9 are connected to one another at the bottom by a ribbed plate 13, the structure of which consists of Bars connected to one another in a grid-like manner in the right part of FIG. 3 as a view from below and in FIG. 6 is shown in more detail in cross section.

For stiffening is in a bottom, in the longitudinal direction Continuous recess of the runners a steel rod 14 with a rectangular cross-section (Figure 6) inserted, which has 8.9 holes for the screws 12 in the area of the feet and together with the feet on the plate 1 is attached.

Since the edges of a pallet are exposed to heavy loads, for example when approaching with Fork lifters, the edges of the plate 1 are reinforced by beads 15 (Figure 'u. 5) and are in the area the feet 8,9 also protected by raised parts 16 of the foot walls »
