Description

Designation: foot for a transport pallet

The invention relates to a foot for a transport pallet, which is made of plastic, has a hollow, expanding basic shape and on the back of a the actual pallet forming plate, in particular made of cardboard, can be fastened.

As is known, a transport pallet is a plate that forms a floor for storage and transport of loads using a forklift.

There are already known pallets that consist of a plate, in particular made of cardboard, which form a base that stands on feet made of plastic, in order to push them underneath the fork of the forklift truck (see for example patents U.K.-A-2 089 316 or US-A-3,377,847 and 3,316,861).

In the French patent FR-A-2 341 493 a method for the production of such feet is described. After that, these feet are made by first rolling up a strip of corrugated cardboard and then attaching it to one Double-sided tape is applied to the end of the resulting cylindrical body. However this was The technology is not very satisfactory, because on the one hand, the manufacture of these feet is expensive because the even in the production of expensive double-sided adhesive tapes

QQ's to be used, and on the other hand, limits the honeycomb structure of the winding produced in this way considerably the contacts between the upper outer surface of the wrapped body and the glue liner, and thus the adhesive properties. In addition, the strength of these feet during use is not very satisfactory, especially as a result of moisture absorption. Because the feet are cylindrical and remain because of their cell structure

eventually the base surface hang on bumps and as a result of insufficient rigidity these feet can under the effect of a shock does not slip, which is to be regarded as a reason for complaint.

The object of the invention is to eliminate these disadvantages and to provide a foot for a transport pallet create that can be produced economically on the one hand, is easily adaptable to small series and to panels of different thicknesses and on the other hand no special material required for its manufacture.

This task is based on a foot for a transport pallet, which is made of plastic, a has hollow, widening basic shape and on the The back of the actual pallet forming plate can be fastened, solved in that the large, open The base of the foot has a wide, horizontal edge strip in the form of a frame, the outer surface of which is coated with an adhesive layer, which in turn is covered with a removable protective film is, which is removable when placing the foot on the back of the plate forming the pallet. It is beneficial when in practice

- The feet are made of plastic, such as PVC, polyethylene, polypropylene, polystyrene injection-molded with fiberglass can be reinforced;

- The widening feet have a shape according to the invention, in particular a truncated cone, even tetragonal Shape or, even better, have a grooved cross-section »in order to achieve better traction in this way.

QQ low surface and better resistance to breakage Offer;

- the adhesive intended to fix these feet to the plate or platform, any Applicable but fast (on the order of a second) setting material. It is essential that this glue is dry, i.e. without water content, so as not to get into the cardboard forming the platform

to penetrate. It is advantageous to use hot-melt adhesives.

Even if the plate is usually flat and forms a transport platform, it can also be the flat floor a transport container consisting in particular of cardboard / like a box pallet or so-called American Palette. The plate can also be made of a material other than cardboard, such as plastic. In an advantageous manner, the attachment points can Feet can be predetermined on the plate, in particular by imprints applied at the same time as the cutting on the back of the plate. In this way, when attaching the feet, the appropriate attachment points can be easily determined, and thus no special personnel is necessary for this.

An embodiment of the invention and the advantages resulting therefrom are illustrated in the following description with reference to the drawing.
^In the drawing shows

In Fig. 1 to 4, the foot 1 according to the invention consists of injection-molded plastic, such as polypropylene. This foot 1 essentially comprises a hollow body 2 on the _f upward (frustoconical) extends and is closed at its small footprint. 3 However, this small floor area 3, in order to

To allow condensates to pass through a small opening 4. That foot is in its upper area (large base of the truncated cone) open, i.e. it has an opening 5 in its center. Next, the Foot in particular, according to the essential feature of the invention, a wide, horizontal edge strip 6 in the form a frame or similar. In order to enable the feet to be stacked one inside the other, i.e. to allow them to be stored comfortably, it is necessary that the inner and outer conicity of the feet is almost identical. So must the diameter the opening 5 must be larger than the outer diameter of the bottom surface 3 / around the passage of the bottom surface 3 through the opening 5 to enable. However, in order to simplify the drawings, these rules are not fully complied with.

The tapered shape with circular cross-section that is essentially conical, can be reinforced by integrally formed support ribs 7, 8, 9 (see FIG. 2).

As an exemplary embodiment, a foot according to FIG. 1 was produced with the following dimensions:

from quick-setting adhesive, such as in particular a hot-melt adhesive, applied, for example based on synthetic rubber. It is advantageous to adjust the glue by means of adjustable To apply melting vessels fed spray nozzles. on In this way, with a square frame (see Fig. 2), four independent strips 14, 15,16,17, for example 1 cm wide, on each of the

Apply four sides, which are indicated by dotted lines. Then the four incoherent adhesive strips 14 - 17 are each subsequently placed on four corresponding protective paper strips 18, 19, 20, 21 made of siliconized paper. These papers have the task of protecting the adhesive layers 14-17. The width and the length of the protective paper strips 18-21 are larger than those of the adhesive strips 14-17, on the one hand the same to protect well and on the other hand to facilitate manual lifting, when the feet of> it is to be glued plate 10 *.

The cardboard plate 10 previously cut, for example to 800 × 1200 mm, has several previously printed Markings 25, for example five here (see FIG. 4). These markings 25 are at the four EcAen of the cardboard sheet 10 at a distance of about 50 to 100 mm from the angles of the and in the center.

To glue the feet 1 to the back of the plate 10, The procedure is as follows: The protective paper strips 18-21 are pulled off by hand. then the adhesive-coated surface of the frame 6 of the foot t is placed on each printed mark 25. Adhere by the immediate setting of the adhesive 14-17 at ambient temperature and simple touch the feet firmly to the plate 10 such that the pallet is ready for use (see Fig. 3).

It goes without saying that the shape of the foot is not limited to the frustoconical or described Limited truncated pyramidal embodiments is, but that other designs, such as polygonal or toothed cross-section or a cylindrical one Shape, etc., are suitable.

In a particularly advantageous embodiment,

gc, shown in Figures 5 and 6, sets in hollow foot 30 made of polypropylene copolymer essentially composed of:

- From a number of regular, symmetrical hollow strips 31 or spikes, for example eight on the Number, with a wall thickness of 1.5 mm, which are arranged in a conical basic shape; - From a number of molded, strut-forming ribs 32, to strengthen the strength of the Frame 33;

- from a frame 33, the general outer shape of which is essentially square with rounded corners 34 is, the thickness of which is also 1.5 mm and which is open in its central region 35;

- from an opening 35 'in the small floor area for the drainage of condensation water.

As previously described, there are four, approximately 1 cm wide, non-contiguous spray nozzles by means of adjustable spray nozzles Strips of hot-melt adhesive, in particular made of rubber, are applied, each from a strip 36 - 39 are covered with siliconized paper, the width and length of the adhesive strips towers.

Placing it on the plate 10 or on the floor a box pallet, as previously described.

Even if the cardboard plate 10 is mostly in the form of a has a flat plate, it can also be formed by the bottom of a box-shaped cardboard container, like a so-called American box. In this way, it is sufficient if with the subject under discussion Container is to be handled to stick to the bottom of the same feet according to the invention, in order to palletize ' Q, i.e. the handling of the same in the same way as pallets with the help of the forks of a forklift.

Even if the plate or the bottom is made of cardboard in the exemplary embodiments described, so can but just as all other suitable materials can be used, for example or even pressed materials better to plastics. This last embodiment (plate made of plastic) enables these pallets to be stored

on wet soil without absorbing moisture. The invention has numerous advantages over the previously known designs. The following are to be mentioned:

- the possibility of adaptation to all thicknesses of the panels, in particular made of cardboard;

- the fact that it is much easier to glue a foot to a plate than to glue a foot to a wooden pallet to screw on or to insert feet in openings previously cut;

- avoiding holes in the plate;

- easy and separate storage of feet and plates;

- the possibility of making small batches on the spot at the last moment, without the use skilled workers, what with the known techniques would not be economically feasible;

- the possibility of handling the so-called American containers (box pallets) in the form of pallets, which was not possible until now; ~ the possibility of sliding, more precisely, of Dislocation under the effect of a side impact without distortion or indentation.

Therefore, the invention can find very versatile applications in the field of manipulation with pallets:

* - be it in the form of pallets themselves (flat plates made of cardboard or other material);

- be it in the form of boxes (stacking boxes made of cardboard, box pallets).
