6 9 8 Ω 9 PALLET - CHIP BALL Ό s O c.

The present invention relates to a pallet, in particular as a pallet, which can be discarded or discarded after use.

Standard-sized pallets are now widely used to transport and store all types of goods. Such pallets are usually made of unplaned boards and pieces. Such truck pallets have the disadvantage that they are heavy and difficult to handle and their manufacture and handling are also costly, especially in terms of handling due to the high weight of the pallets, often 30-40 kg. In recent years, wood has become more and more expensive and more expensive, and efforts have been made to build pallets which have a lower weight and thus 15 require less raw material and thus become cheaper to manufacture and also use. It should be noted that the weight of the pallet is in itself important because the freight cost is calculated based on the load on the pallet and the total weight of the pallet. There are still handling and return freight costs. Efforts have also been made to make pallets from corrugated board, sheet metal and various types of foamed plastics with or without reinforcement. However, such pallets have not been commercially successful.

Thus, there is a great need for a pallet that combines the following features: low cost, low weight, high flexibility in use, not bulky during storage, as it can be stored in the form of separate parts that can be easily assembled at the loading site and easily disassembled if desired. , e.g. by burning as non-harmful gases. The present invention relates to such a pallet.

The aforementioned previously known alternative pallets 35 are intended mainly for light or medium weight goods. However, an important feature of cargo butter is that it must be possible to handle them with fork cranes on all three sides, i. the forklift must be able to lift pallets on all 5 sides, the long forklift must be able to lift several pallets at the same time. However, the aforementioned previously known alternative truck platforms can most often be lifted from two sides, which has caused a considerable limitation of usability and lack of economy. An important object of the present invention is to provide a low-cost pallet that can be handled by all four sides of a forklift truck.

According to the present invention, a pallet has been developed, in particular a pallet, which is so inexpensive that it can be used only once and then discarded as described below with reference to the accompanying drawing, which shows a pallet in perspective view according to a particular embodiment of the present invention.

The special primary-shaped pallet shown in the drawing comprises three leg members I, the two outermost of which at one time form the outer edges of the pallet. The shown load 1 also has an intermediate leg member 1. The leg members 1 have two 2.5 symmetrically arranged recesses at such a distance from each other that they correspond to the distance between the forks of a conventional standardized forklift. The footrests 1 are provided with a plurality of openings evenly distributed along the length of the foot members towards 30 directly with respect to these and at a short distance from or laterally from the upper surface of the foot members. The leg members 1 are connected to each other by tubes 4 placed through the openings 3. The outer diameters of the tubes are such that they can be passed relatively easily through the openings 3 of the leg members 35. The pallet according to the invention can thus be assembled in a simple manner using two, three or more leg members 1 and a suitable number of tubes 69802 placed through the openings. Practical experiments have shown that the load 1a11a according to the invention has considerable strength and that there is no risk, due to the friction between the leg members and the tubes, that the tube would accidentally leave or come loose from its right place. The pallet according to the invention also has a certain elasticity in the direction of the diagonal, which makes the pallet able to withstand impacts without breaking or causing other damage to the leg members.

It is preferred to make the leg members from wood, with the wood fibers being substantially parallel to the length of the leg members, but other materials may be used. Examples of such materials are plywood, sheet, etc. Plastic materials can also be used and also deep drawn sheet or cast aluminum.

The tubes 4 can be made of any suitable inexpensive material, such as metal and various types of plastics, but for cost reasons it is preferable to make the tubes from paper. Such tubes 2u are conventionally made by wrapping paper webs around a core. Using a water-resistant adhesive on the finished pallet makes it water-resistant. Practical experiments have shown that a suitable diameter of paper tubes is 45-60 mm with a material thickness of 2-5 mm.

The height of the leg members is about 160 mm and their thickness can vary considerably, e.g. between 20-100 mm, in particular about 25-35 mm. In the case of conventional pallet sizes and with a pipe diameter of about 48 mm and a material thickness of 4 mm and a leg member thickness of 25 mm, the pallet according to the invention weighs about 6-8 kg. This, of course, means that a significant reduction in the cost of handling and transporting the goods can be achieved. The pallet according to the invention can, of course, be used more than once, but practical calculations have shown that the manufacturing costs of the 69802 pallet according to the invention are lower than the costs caused by conventional pallets when considering freight, return, repair and the like. costs.

This means that the pallet according to the invention can be discarded once it has been used without financial loss. The primary choice of material for the load according to the invention makes it possible to dispose of it, for example, by burning without generating harmful gases.

In view of the above, it is obvious that the tubes and the foot rail do not need to be attached to each other in particular. Due to the number of tubes and the three leg members generally used, these parts are always in a tension state with respect to each other, which causes the different parts to be effectively fastened to each other, especially when the platform is loaded. However, it is of course important that the fitting of the pipes to the diameter of the openings in the leg members is carried out as accurately as possible, which also facilitates the assembly of the pallet at the loading age 1 la. One particularly suitable way of accomplishing this is to rub the inner surfaces of the openings after drilling these with a circular roughening tool 11a, such as a steel fiber brush 1a. With such a treatment, a layer 25 of free fiber ends is formed in the openings, which causes some friction on the tubes. Also, any dimensional changes that are likely to occur to the wood materials as a result of the change in the humidity of the ambient air are thus compensated.

30 As mentioned above, the leg members and tubes are stored separately, which results in a significant reduction in the required storage space compared to conventional pallets. The assembly of the parts is suitably performed using a suitable guide, in which case the leg members, two, three or more, are placed on top of each other, after which the desired number of tubes is placed in the openings. (For light loads, some of the pipes can of course be omitted). The free ends of the tubes are fixed, and the gripping members of the guide 69802 5 then move the outer leg members resting on the tubes to their intended position. Other devices for assembling a pallet according to the invention can, of course, be provided, as is appropriate in different cases.
