Description:

THE METAL PALLET TRAY AND STACKING SYSTEM

Technical Field

The invention relates to a metal pallet and a system for stacking it in a container. Specifically, the metal pallet has an attaching frame that is at the same time functioning as a supporting frame for the pallet stacked on it.

Background Art: Recently, the use of pallet is very extensive, both for handling hard materials and soft materials. The use of pallet seems to be very practical, where goods placed on it will be orderly arranged and fixed in amount so that this makes a positive impact for trade activities particularly in shipping goods and loading or unloading them. The goods are still in the ordered stacking and with a countable amount or in other words, they could be counted exactly if there is a difference amount of goods in a pallet . Conventionally, a pallet is generally made from wood or plastic materials, which are apparently cheap in cost for making them. However, due to environment aspects recently, wood constitutes protected raw materials, which are limited for the purpose of environmental preservation.

Goods placed on a pallet commonly has a fixed quantity and packed using plastic ropes or wires or other materials in order to make them strongly tied to the pallet. However, there is a problem in the practice to arrange pallets both in storage cabins and in containers for later shipping of the goods. When pallets are arranged in row lines, there will be a necessity for a very big space or yard. Whereas, if pallets are arranged in a stacking, another problem will exist where the goods

placed in the bottom part of stacking will be broken, particularly if the goods are fragile or at least, the packaging or supporting for the goods in the bottom part will be broken. US Patent US-6880311 disclosed a system and device for stacking the goods on a pallet, wherein the pallet had a wall surrounding the stacked goods so that the goods placed inside will always be in a stable position. Also Patent US 6327984 described a pallet having a foldable pallet floor. The pallet floor has two or more foldable wings at its respective ends and its central part. With these foldable wings in which the pallet leg holes are placed on it, this make the pallet legs could be kept inside the pallet leg holes existing under the wings. Then, the pallets could be shipped and stored in a stack and this does not need a big storage room.

Another Patent US 6095292 disclosed a metal pallet where its floor part was made of a plate in arrangement of intersecting with a number of concrete metal, where the concrete metal are piled in the plate with welding so upper surface is confined by the concrete metal while it is also confined by the metal plate.

Among several pallets described above, none of them disclosed the system to stack pallets in loaded conditions, yet it had been disclosed that the problems frequently happened in the practice where goods could be broken due to very extensive load or impossibility to stack loaded pallets on other loaded pallets.

Thus, the invention has an objective to solve the problem happened or to improve the pallets existing previously .

Disclosure of Invention

According to the above-mentioned objective, the invention is to provide a loaded pallet in vertically layered arrangement.

The first embodiment of the invention is a pallet as depicted in figure 1, which is a perspective view of a pallet (1) with an attachment frame (2), which also functions as supporting frame in an attached condition. The pallet (1) is preferably made of a metal plate material or steel plate, or combination of wood and steel, or combination of plastic and steel. Pallet (1) comprises a floor or body (3) wherein around the body (3) is provided with frame (4) forming a pallet contour, the frame (4) is made a little bit higher than the body (3) thus taking the form of a tray; furthermore the body (3) is supported upwardly by several legs (5), the legs (5) are also made of steel material, the legs (5) are arranged in a row of three or four lines according to the desired pallet design, the legs (5) are interconnected with the connecting plate (6) to support the said legs

(5), the legs (5) also are tied up to the floor or pallet body (3) by welding, in the bottom part design (7) there is provided a groove (8) crossing or lengthwise to make correctly the placement of the supporting frame (2); and an attachment frame functioning also as the supporting frame (2) made of several pieces steel pipes and steel plate, steel pipe pieces and the steel plate are assembled to make an attachment frame functioning also as

a supporting frame (2) through a threaded conn ection or knock-down connection, or a slot connection, or other connections, the attachment frame or also the supporting frame is attached to the holes provided in the frame part (4) of the pallet body (3).

Referring to figure 2, it is a perspective view of the pallet (1) wherein the attachment frame functioning also as a supporting frame (2) is in a detached condition. The steel pipe pieces and steel plate as part of the supporting frame (2) could be detached one by one and arranged on the floor (3) surrounded by frame (4), thus the steel pipe pieces and steel plate as the part of supporting frame may be kept neatly. This figure also shows the bottom part of the pallet that are two grooves (8) crossing of the pallet width (1) functioning to sit properly the pallet on the supporting frame, so that enabling one pallet to be stacked on another one. The pallet (1) as described above is characterized that the attachment frame (2} are made of steel pipes combined with plate, the steel pipes and plate are formed to take the shape of wall frame pairs capable of interconnected and detached, while the steel plate can be made as the support and also functions as the product or goods identifying device in the pallet. Figure 3 shows a perspective side view of the pallet

(1) wherein the attachment frame, which also functions as the supporting frame (2) is in detached position. In this figure one can see clearly the arrangement of the pallet's legs (5) arranged in row of three lines. Referring to figure 4, it is a perspective view of the pallet (1) without stacked loads. The pallet (1) with its respective attachment frames as well as supporting frames (2) is in a vertical arrangement. Grooves (8) in the bottom part of the pallet are placed exactly on the

frame (2) so that each of stacked pallets in vertical arrangement could be stable. The attachment frame as well as the supporting frame (2) stands vertically to strongly support the pallets (1) . Figure 5 shows a perspective view of loaded pallet according to the invention. Pallet (1) of the invention is capable to contain goods (9) already packed with packaging materials. Furthermore, goods (9) are tied up to the attachment frame as well as the supporting frame (2) . With the attachment frame as well as the supporting frame (2) have been already orderly arranged, another similar pallet could also be set as well. Further step is to arrange the loaded pallets in the storage room or the shipping container. This step could be shown in the figure 6, wherein a perspective view of loaded pallets are in stacked arrangement or in other words vertically stacked. Loaded pallet is stacked on another loaded pallet each other. The most important thing in this regard is bottom grooves should be set exactly on the supporting frame of the bottom pallet, so that the arrangement of loaded pallets could be stable and sturdy.

The arrangement system of loaded pallet in vertical mode according to the present invention comprising of: a loaded goods placed on the pallet floor must regard the acceptable pile height; an attachment frame assembly is inserted and fit to holes on pallet floor frame, so that the said loaded goods can be stably safely attached to said pallet; and an arrangement of the loaded pallets one on top of the others are orderly arranged by using attaching frame of the bottom pallet as supporting frame of the above pallet.

That is all the invention as described through embodiment and/or figures. However those figures and the explanations do not limit the invention to the above-given

details. It is contemplated that various modifications and substitutions can be made by person skilled in the art without departing from the spirit and scope of the following invention claims.
