Description

The invention relates to a pallet according to the preamble of claim 1.

From DE 91 14 035 U1 a pallet is known, which consists of a pallet plate with openings for receiving pallet feet. The pallet feet are formed as open to a top of the pallet plate hollow body and have a collar which projects beyond a peripheral platform. Each palette foot cooperates with a flange, which is snapped into the Palettenfuß and clamps the plate plate. A disadvantage of such a pallet structure is the high assembly costs due to the large number of items. Each pallet base must be secured in the pallet known from the prior art by a flange on the pallet. Furthermore, the grid between the pallet base and the flange must be matched to the thickness of the pallet plate in order to clamp the pallet plate between the pallet base and the flange exactly. Finally, the flange forms an elevation with respect to an upper side of the pallet plate, which elevation can lead to damage of the transported goods during the transport of sensitive goods.

The invention has for its object to develop a pallet in which the assembly and disassembly of the pallet feet on the pallet plate is simplified and which consists of as few items as possible, the pallet feet should be usable for different thicknesses pallet plates and on the pallet plate by the pallet feet no disturbing elevations occur.

This object is achieved on the basis of the features of the preamble of claim 1 by the characterizing features of claim 1. In the dependent claims advantageous and expedient developments are given.

The pallet according to the invention has a pallet base with a collar which carries on its outer surface a structure by means of which a positive engagement with a collar surface of a breakthrough in the pallet plate can be generated. This makes it possible to quickly and safely attach the pallet base on the pallet plate via the lying between the top and the bottom of the pallet plate collar surface of the opening by simply wrapping without the need for additional components. The core of the invention is thus a pallet with a one-piece Palettenfuß, which by a special design of the outer surface of his collar as a contact surface uncomplicated and quick attachment to the mating contact surface .. forming collar surface of a breakthrough in a pallet plate allows and thereby streamlines the manufacturing process.

The invention provides to provide the structure of the outer surface of the collar of the pallet base with ribs and / or with a thread and / or with elevations, such as cones, pyramids or hemispheres and / or with wedges. As a result, optimal cohesion can be achieved with a wide variety of materials of Palettenfuß and pallet plate.

According to the invention, the outer surface of the collar is perpendicular to an upper side of the pallet plate align. By such an orientation of the outer surface of the corresponding breakthrough in the pallet plate with the simplest means can be produced.

Furthermore, the invention provides, the outer surface of the collar and the collar surface of the opening to be inclined to the top of the pallet plate, this are about corresponding angle α , β provided, for the collar angle α and for the collar angle β in particular 60 ° to 90 ° are provided. With such an inclination of the opposing contact surfaces, it is possible to protect the collar surface of the opening in the pallet plate in a corner area and not unnecessarily burden this when driving the Palettenfußes by vorbeigleitende structure of the outer surface.

A similar protection of the collar surface is also possible by a structure of the outer surface, which has a projection depth which increases towards the platform of the pallet base.

According to the invention it is provided to form the hollow body with a circular, polygonal or elliptical cross-section, the circular cross-section simplifies the assembly of the pallet base, as its orientation when driving into the pallet plate must be disregarded and the polygonal or elliptical cross-section of a causes additional rotation of the pallet base in the pallet plate.

The invention provides to provide the Palettenfuß at its bottom and / or its side walls with at least one breakthrough. As a result, the adherence of nested palette feet is effectively avoided.

Furthermore, the invention provides, at least one projection on the bottom and / or on the side walls of the pallet foot form, which is designed in particular as a rib. By means of such ribs, it is possible to accurately predetermine the minimum distance between two stacked pallet feet in order to avoid the tilting of a pallet stack.

In particular, the invention also provides to connect the bottom and the side wall of the pallet base by the rib. This makes it possible to increase the stability of the pallet foot.

Furthermore, the invention provides to arrange a stacking corner on the platform of the pallet base in order to prevent the lateral slipping of stacked goods and to avoid additional installation effort for individual stacking corners.

Finally, the invention provides for striking or knocking the pallet foot in or out of the pallet plate in the z-direction or z'-direction. This assembly and disassembly are quickly and easily possible.

Further details of the invention are described in the drawing with reference to schematically illustrated Ausführungsbeisielen.

In the figure 1a, a pallet 1 is shown in side view. Die.Palette 1 consists essentially of a pallet plate 2 and pallet feet. 3

Figures 1b and 1c show these items. The pallet plate 2 shown in FIG. 1b has four apertures 4, into which pallet feet can be inserted from an arrow direction z for completion. The openings 4 are each bounded by a circumferential collar surface 5. Furthermore, the pallet plate 2 has a top 6 and a bottom 7, which are spaced from each other by a pallet plate thickness D.

FIG. 1c shows one of the pallet feet 3 known from FIG. 1a in an enlarged and perspective view. The pallet base 3 is designed as an upwardly open hollow body, which has a collar 8 in an upper section A, which merges into a platform 9. In a lower section B, the pallet foot 3 defined by four side walls 10 and a bottom 11. An outer surface 12 of the collar 8 has a structure 13, which is formed by circumferential ribs 14. The platform 9 forms a bearing surface AF for the underside 7 of the pallet plate 2 (see FIG. 1b).

FIGS. 2a to 2c show a variant of a pallet foot 3. FIG. 2a shows a section through the plan view shown in FIG. 2b along a section line IIa-IIa, the hatching of the cut surfaces being dispensed with for clarity. In an upper section A, the pallet base 3 has a platform 9 and a collar 8 approximately perpendicular to it. These go in a lower portion B of the pallet base 3 in side walls 10, which extend to a bottom 11 out. The side walls 10 and the bottom 11 are connected to each other via ribs 15 (see also Figure 2b). The ribs 15 serve to stabilize the pallet base 3 and as supports 16 for a further pallet base (not shown) inserted into the pallet base 3 from an arrow direction z '. The bottom 11 has four through holes 17 (see Figure 2b), through which water can drain and which facilitate the separation of telescoped palette feet. In the area of the platform 9, the pallet base 3 has an approximately rectangular cross-section Q parallel to the plane of the drawing. FIG. 2c shows a section through the pallet base 3 along a section line IIc-IIc drawn in FIG. 2b. The bottom 11 is slightly curved in an arrow direction z, in order to additionally achieve stability and to promote the drainage of water. A structure 13 present on an outer surface 12 of the collar 8 is not shown in detail in FIGS. 2a to 2c, but provided.

FIGS. 3a and 3b show two partial views of two pallets 1, 1 'stacked one inside the other.

In FIG. 3a, in the case of each pallet 1, 1 ', a pallet plate 2 is gripped in a form-fitting manner by a structure 13 of an outer surface 12 of a collar 8 of a pallet foot 3. For this purpose, ribs 14 engage positively in a collar surface 5 of a breakthrough 4 of the pallet plate 2. The pallet plate 2 rests with a bottom 7 on each of a bearing surface AF formed by a platform 9. Mit.einem bottom 11 is in the lower pallet 1 'stacked upper pallet 1 on ribs 15 (only one rib is visible here) and is thus kept at a defined distance. Side walls 10 of the stacked pallet feet 3 are parallel to each other. In FIG. 3 a, a thickness D of the pallet plate 2 corresponds to a collar height K H of the collar 8.

FIG. 3b essentially corresponds to FIG. 3a. In contrast to FIG. 3a, a thickness D of the pallet plates 2 belonging to pallets 1, 1 'is greater than a collar height KH of collar 8 of the pallet feet 3. This shows that the pallet feet 3 according to the invention can be combined with all pallet plates 2 if the condition D> = KH is satisfied.

FIG. 4 shows a detail of another pallet 1. A pallet base 3 here has a structure 13 consisting of ribs 14. In contrast to the structures illustrated in the preceding figures, the ribs 14 have different projection depths VT or VT1, VT2. In this case, the projection depth VT increases toward a platform 9 of the pallet base 3 (VT1 <VT2). As a result, excessive stress on the pallet plate 2 in a corner region E is avoided by the multiplicity of ribs 14 sliding past the pallet base 3 in an arrow direction z. Furthermore, it is ensured by the larger ribs 14 lying in the region of a platform 9 that, despite one Bexeits made load on the corner E a good form fit arises.

5 shows a section of a further pallet 1. Here, all the ribs 14, which form a structure 13 of an outer surface 12 of a collar 8 of a pallet base 3, have the same projection depth VT. In contrast to the embodiments shown in the preceding figures, however, the outer surface 12 or the structure 13, the collar 8 is not perpendicular to a top 6 of the pallet plate 2, but has a collar angle a , which is about 58 °. A co-operating with the outer surface 12 of the collar 8 of the pallet base 3 collar surface 5 of the pallet plate 2 has a corresponding collar angle β = 58 °. By this construction, it is possible to load the collar surface 5 in each area only with the rib 14, with: which cooperates this area also form fit. As a result, in particular a high load of a. Corners area. E the pallet plate 2 avoided.
