Skid pallet

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

Transport pallets are known in many variations. In addition to wooden pallets, there have long been one-piece or single-piece Half-shell made plastic pallets, which for stiffening also already with inserts made of steel or other 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 that is particularly stable and load-bearing compared to known skid pallets and it does not require a great deal of effort in terms of both material and manufacture.

To achieve the object, the invention is based on a skid pallet of the type mentioned and is characterized in that the upper part is a one-piece cover plate made of compressed wood and provided with reinforcements 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 not very sensitive to wear. In contrast, the plastic injection-molded runners ensure long-term durability, even with rough handling and occurring load surges. You are insensitive when placing the pallets on a damp

or greasy surfaces and are easy to clean.

In addition to separate runners, for example three runners running in the longitudinal direction of a rectangular pallet Plastic runners added to a window cross can also be used. Such a lower part can be assembled or molded from one piece.

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 a reinforcement corresponding to the grooves on the underside has bulges. 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 form with at least one drainage point in the runner area. Rainwater or also at Liquids that leak from broken vessels can then run off quickly and in a controlled manner.

To save weight and increase strength, the runners are recommended by Invention two outer and at least one middle foot formed from a hollow body, the bottom side are connected by a ribbed plate, in the edge area and especially in the corner area Feet arranged on the pallet are advantageously pulled up on the cover plate as edge protection. The pressed wood cover plate, which is located on the edges against hard impacts, is thus effectively protected.

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

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

Figure 1 is a plan view of a rectangular three-skid pallet according to the invention;

FLgor 2 shows 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 in Figure 1 are only shown in dashed lines and are to be described in more detail below.

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

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.

Figure 4 shows the cross section of the plate 1 in the edge area corresponding to the section line IV-IV in Figure Ί. The grooves correspond to beads 7 on the underside of the plate 1, so that overall reinforcement results from the profiling without additional material expenditure. Depending on the distribution of the grooves, the profiling in the other areas of the plate is similar. In this case, the grooves need not necessarily be associated with corresponding beads, _J rather troughs and ridges may also be arranged independently of each other.

In desirably the surface of the plate 1 made of compressed wood has a certain roughness, which prevents too easy sliding of the patch goods, but even if they have a smooth bottom * _n teresse good flow properties in the I for the reason of the troughs 4 a smoother

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. With higher demands The surface quality of the pallets can, as is known per se, be compensated in the form of co-pressed Sheets made of laminate resin are made, roughening, if necessary, by sandblasting can be made.

The structure of an outer runner 2 and its connection to the plate 1 is more precise 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 legs 8 and a central foot 9 which are formed corresponding to the sectional representation in the left part of the figure 2 by a hollow body. In the center of the rectangular or square (middle runner 3) shaped feet 8,9 is a tubular support 11 held by cut-out webs 10, through which, as FIG . The cover plate has a storage socket 13 for receiving the screw head. Instead of a carriage screw 12

A hollow rivet (not shown) can also be used as a connecting element.

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 is composed 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 4 and 5) and are in the area the feet 8,9 also protected by raised parts 16 of the foot walls.
