Description

Technical field

The present invention is in the field of transport and warehouse management and relates in particular to devices for handling materials and products, in particular pallets of various constructions.

BACKGROUND OF THE INVENTION

Initially, flat pallets were only used for their original purpose, which means transporting and handling, or possibly storing, more permanently such goods that could not fall off the pallet when the pallet was handled approximately horizontally. Such goods include plate or prismatic items such as bricks, building blocks, bulk packaged materials such as cement, lime in the construction industry, sugar, flour, rice, cereals in the food industry and agriculture, and possibly also goods packed in boxes, boxes or boxes. Due to the widespread expansion of flat pallet transport worldwide and the increase in the number of pallets around the world, pallet handling has also been considerably accelerated, so that additional measures have to be taken to secure goods on the pallets against slipping. In this context, various ways of transporting goods and anchoring them on a pallet have been developed.

Easily assembled and dismountable, economically transportable flat pallet attachments, which would allow their use for other purposes, eg. for the transport and storage of bar stock or the size of smaller and unpackaged products such as flat pallet accessories on the market are rare. Specialized pallet solutions for all possible purposes are also available in the specialist literature collections. For spatial resp. t. Vol. The inventors have focused on solutions that rationalize the return of empty pallets by making the side walls of the pallets detachable, collapsible or collapsible, thereby substantially reducing the volume of the pallet during return transport and reducing the cost of return transport.

There is only a small number of such flat pallet accessories that would be conventional flat pallets, e.g. t.zv. The EURO-pallets have enabled general and universal use, after very simple and quick assembly work when installing the superstructure.

Solutions having the characteristics described in the previous paragraph most often have the disadvantage that they either cause the outer dimensions of the base flat pallet to change, i.e. enlarge it, or the disadvantage that various mechanical adjustments must be made to the base pallet, e.g. by drilling, screwing or screwing on various components, the original flat pallet loses its normalized quality.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a pallet system which, without having to make mechanical adjustments on a flat pallet while maintaining the external dimensions, allows them to be used for the transport of piece goods. However, the use of this newly developed add-on pallet system is conditional on the use of already known technical solutions, which could be characterized e.g. properties of the subject of patent no. 279 898, or the properties of the utility model subject of Germany no. G 93 04 124.1. The subject matter of both documents is a holder with perpendicular stands on which the individual segments of the superstructure system according to the invention are slid. An important feature of the holders is that they are slidable along the long side of the flat pallet, which greatly facilitates the installation of the superstructure segments according to the present invention.

The advantage of the superstructure pallet system according to the invention is that no part of the superstructure components extends beyond the outer contours of the flat pallet, and also that no mechanical adjustments need to be made on the flat pallet in order to make the superstructure possible.

The invention therefore relates to a flat pallet extension system comprising end segments of the "C" -shaped plan view and straight side segments provided with connecting eyelets. The connection of the end segments to the side segments or the two end segments is effected by means of connecting rods.

The side segments may be replaced by suspension segments provided with coupling hooks for connection to the end segments. The individual types of pallet superstructure segments can be freely combined with each other.

The main and essential features of the invention of the flat pallet extension system are that the lateral arms of the end segments are provided with sleeves which serve to slide the segments onto the support stands, thereby positioning them on the flat pallet. The superstructure may be closed on the pallet either by hanging the suspension segments into the connecting lugs of the end segments, and / or by connecting the connecting lugs of the end segments to the connecting lugs of the side segments by means of a connecting rod. The connecting lugs of the end and side segments as well as the connecting hooks of the suspension segments can advantageously be made of the overlapping ends of the horizontal elements of the segments by curling or bending.

Individual segments can be produced eg. grid reinforcing mats as shown in the accompanying drawings, or solid material e.g. Sheets, plates of plastic or wood.

Fig. 1 shows an example of a complete flat pallet extension system at the stage of its assembly on a pallet. It consists of two end segments, one side segment, one suspension segment and two tie rods. Furthermore, it shows a basic flat pallet with holders mounted on it. One of the end segments is already slid onto the bracket stands, the other end segment is being slid onto the bracket stands. The side segment is pushed onto the end segments so that the connecting eyelets of both segments are coaxial, and by inserting the connecting rods into the connecting eyelet holes, the three segments are firmly joined. On the free side of the superstructure, the suspension segment is hinged to the connecting lugs of the end segments with its connecting hooks.

DETAILED DESCRIPTION OF THE INVENTION

The attached pictures show the extension system for flat pallets, made of a grid mat, and all detailed parts of the superstructure are adapted to this starting material. Being the most complicated embodiment of the superstructure, it has been chosen to illustrate and describe the subject matter of the invention.

Thus, the invention relates to a flat pallet extension system comprising a base pallet 23 and a vertical stand holder 17 clamped thereon, end segments 11 of the "C" -shaped shape and straight side segments 12. provided with connecting eyelets 14 and / or from straight suspension segments 25 provided with connecting hooks 20. The joining of the side segments 12 with the end segments 11 is performed by connecting rods 18. The simplest assembly of the superstructure system can be a superstructure consisting of only two end segments 11 The individual segments H, 12 and 25 can be combined with one another at will.

The main features of the present invention are that the superstructure system consists of end segments 11 and side segments 12 provided with connecting lugs 14 or hinged segments 25 provided with connecting hooks 20 and a connecting system formed by either a combination of connecting lugs 14 of end segments 11 and side segments 12 and of the connecting rods 18, or by combining the connecting lugs 14 of the end segments 11 with the connecting hooks 20 of the hinge segments 25.

Further, the side panels 24 of the end segments 11 are provided with sleeves 13 arranged exactly one above the other and that the ends of the horizontal elements 16 of the end segments 11 are provided with coaxial connecting lugs 14 for hanging the suspension segments 25 and / or connecting with the lugs 14 of the side segments 12. by means of connecting rods 18, wherein the sleeves 13 extend into the interior of the superstructure and are fixed to the horizontal elements 16 of the sidewalls 24,

Another essential feature of the solution is also that the suspension segments 25 for hanging into the connecting lugs 14 of the end segments 11 are provided with connecting hooks 20 with a vertical part 19, to which the inclined part 26 is connected.

All the horizontal elements 16 of the end segments 11 and the side segments 12 are provided with connecting lugs 14, preferably made by rounding the free ends of the horizontal elements 16 and strengthening them with an end weld

The simplest alternative solution of the present invention is a superstructure consisting of a pallet 23, holders 17 and two end segments 11 directly connected to each other by a connecting rod 18.

Another embodiment of the object of the present invention is a flat pallet superstructure, whose sleeves 13 are formed alternately inwardly and outwardly bent portions of the horizontal first portions 16 of the sidewalls 24 of the end segments 11.

The assembly of the superstructure is carried out as follows: The holders 17 are attached to the pallet 23 and the holders 17 are fixed to the holders 17 fixedly connected to the sidewalls 24 of the end segments H. If the superstructure consists of only two end segments H, they are connected with two connecting rods 18 and the pallet is ready for use.

If the superstructure consists of two end segments 11 and side segments 12, four connecting rods 18, inserted by their shanks 27 into the holes of the connecting lugs 14, secure their connection until the nose 28 of the connecting rod 18 rests on the upper connecting lug 14.

If two end segments 11 and two hinge segments 25 are used to complete the superstructure, the fastening hooks 20 of the hinge segments 25 secure the superstructure closure.

As far as the material of the end segments 11, side segments 12 and hinge segments 25 are concerned, they can be made of lattice mats consisting of vertical elements 15 and horizontal elements 16 permanently connected to each other, as shown in the accompanying figures, but also of solid construction material, such as sheet metal, wood, woodboard or plastic boards.
