Description

A SUPPORT FOR A LOAD Field of the Invention

The present invention relates to haulage of goods, freight handling and storage systems. Background of the Invention

The most commonly used method for transporting goods in the transport industry involves the use of pallets. Goods are loaded onto pallets and the pallets are transported with the goods from one location to another. Pallets are generally made of wood and are leased off of the owner which leads to obvious shortcomings as outlined in the co-pending provisional patent application by Franc Coonan lodged on the 4 September 1998 and incorporated herein by reference. By using pallets to transport goods additional loads are created for the transporting vehicle to carry. However, the problem is that at present the pallets are necessary because transporting goods without pallets would mean that the goods must be loaded and unloaded from transporting vehicles directly. At present a pallet is needed in order to successfully lift and move goods using tines of a forklift. Without the use of pallets most goods invariably would not be adapted to receive the tines of a forklift and therefore could not be easily carried. In a typical warehousing situation boxes of goods may be stored on shelves . Boxes can be transported from one location to another using a forklift, but if the boxes are stored on pallets extra care is required by the forklift operator in order to manoeuvre tines of the forklift to lift boxes without damaging them. If the boxes are not stored on pallets this becomes almost impossible as it is not easy to manoeuvre tines between the bottom of a box and the top surface of a shelf on which it is supported. This problem applies to any surface on which goods are loaded or stored directly without an interposing pallet.

The present invention provides an alternative to existing methods of handling loads whether it be for storage or general transportation. Summary of the Invention

Figure 1 shows a support may be the floor of a truck or the top surface of a shelf. Assuming the support surface 10 is the shape of the floor of a vehicle used for transporting goods, the floor is shown to have a series of identical rectangular ridges 11 arranged side by side in parallel separated by rectangular channels 12. The floor 10 may be a fixed structure forming part of the vehicle or could be in the form of a rectangular mat-like structure or decking which is placed on the floor of the vehicle. Ideally this mat-like structure would be rigid so that the ridges are able to support thereon loads in the form of goods which must be transported by the vehicle. Alternatively the mats could be disposable or clip-on.

In a typical transporting operation a forklift would lift up a box of items or goods to be transported and would raise its tines so that they are at the same level as the troughs 12 of the floor 10. The tines would then be extended to slide into the troughs 12 so that the box of items would be located above the ridges 11. The tines would then be lowered slightly so that the weight of the box is carried by some of the ridges and then the tines could then be removed thus leaving the box supported on the ridges 11.

The number of tines used can be varied.

When the box has been delivered to its destination by the vehicle a forklift can be used to lift the box off of the ridges again by inserting the tines into the troughs 12 and raising the tines so that the box is lifted above the ridges. The box can then be deposited at a suitable receiving location. By using the specially shaped floor having ridges 11 and troughs 12 as shown in Figure 1, it is not necessary to use a pallet.

The shape of the upper surface 13 of the floor 10 may be changed without departing from the inventive concept. Thus as shown in Figure 2 a triangular or saw-tooth upper surface 14 may be utilised. The saw-tooth upper surface has sharp peaks 15 and troughs 16. In the manner as described before a load such as a box of items is able to be supported on the peaks 15 and the tines of a forklift are able to fit into the space between the peaks 15. Ideally however the shape of the tines would be designed so that they conform to the shape of the space between peaks 15, thus rather than having a rectangular cross-section they may have a triangular cross-section. In Figure 2 the support 17 is shown as a sheet of material having a constant thickness . This sheet can be placed on the floor of a truck used for transporting goods and goods supported on the peaks 15 may be removed from the sheet 17. Alternatively the sheet 17 may be lifted with the goods located on it, for example by inserting the tines in the spaces 18 underneath each of the peaks and separated by the valleys 16. Because the floor in Figure 2 is formed from a sheet 17, if the sheet is inverted it can still function in the same way because both sides are identical in the formation of peaks 15 and valleys 16. It should be noted that although in Figure 2 a saw-tooth shaped sheet has been described other shapes are also envisaged which have a periodic waveform shape, such as the square waveform shape shown in Figure 1.

The sheet structure 1 shown in Figure 2 may be used as a pallet. Ideally however in this application the shape would be more of a regular series of ridges and recesses as shown in Figure 1. Depending upon the application it may also be necessary to strengthen the supporting surface by having webbing or bracing formed beneath the peaks 15 if the support surface is formed in a sheet. Figure 3 shows another embodiment of the invention in which a pallet 20 is shown having rectangular ridges 21 arranged in parallel side by side and separated by rectangular recesses 22. The ridges 21 may be formed to have a constant thickness 23 and each of the ridges 21 may be formed on a planar base surface 24.

Each of the ridges 21 is hollow and has a cavity 25 located therethrough along its length.

In use the support 20 may be used as a pallet or in the form of a mat or floor covering for any surface which is designed to support a load. Thus if the support 20 is used on a shelving system it may be formed as a series of rectangular or square mats which can be placed over the shelving with the cavities 25 facing outwardly. A forklift can then lift a load to be stored and place it on the ridges 21 by sliding its tines into the recesses 22 located between the ridges 21.

If at any stage it is necessary to lift the load and the support 20 the tines can be inserted into the cavities 25 and the support 20 and load can be lifted together.

The size of the support 20 may be selected depending upon the application. Thus they may be made as small pallet sized structures which may be rigid if it is desired to carry a significant load and a series of these supports may be connected together to form a complete floor. Alternatively one or more large supports may be formed which may be ten times the size of a normal pallet for example . It can be seen from the above that the supports in accordance with the present invention may be part of a modularised system. There is no restriction on the size or shape of the support and the support is adaptable to be used in a similar fashion to a pallet but equally may be left in a fixed location so that only the goods which they are supported need to be removed. Thus in a warehouse application shelving may be provided with the supports forming the upper surface of each shelf and the supports may be fixed in location or may be removable like a mat or sheet.

If the supports 20 are used as pallets they are not restricted to being of the same size or shape. They can also be made much lighter by making them from lighter materials and they can be made by moulding them from plastic or forming metal or plastic extrusions.

According to another embodiment of the present invention shown in Figures 4a to 4c a support 30 is shown which has added flexibility of use.

In the embodiments previously described the support or supporting surface had ridges and valleys which enabled tines of a forklift to be inserted into the valleys which faced the forklift. As shown in Figure 4 it is possible to make a support or supporting surface which enables tines to lift or deposit a load on the support or support surface at more than just one approach angle. Thus in Figure 4 flat ridges 31 are provided in a matrix of columns 32 and rows 33. Between each of the rows and columns 32, 33 the valleys or recesses are also provided 34, 35. Furthermore, these valleys and recesses may be formed diagonally between ridges 31 as represented by items 36, 37. Therefore the tines of a forklift are able to be inserted at a number of different approach angles with respect to the ridges 31 to therefore deposit goods onto the ridges 31 by approaching the support or support surface 30 at a number of different approach angles corresponding to the line of valleys and recesses 34, 35 and 36.

As previously described above, the support 30 shown in Figure 4 may be a distinct component such as a pallet or may be an integrally formed part of a floor.

As shown in Figure 5a and 5b a pallet 40 may be made from three rectangular bars making a sub-frame 41 or channels which are connected together for a specific use, which may include a subframe.

On top of the subframe 41 a series of parallel elongate rectangular elements 42 are provided.

In the embodiment shown in Figures 5a and 5b, five elongate elements are provided including three thin elongate elements 43 and two wider elongate elements 44 interposed between the three thin elements 43.

A space is provided between each of the elongate elements 43, 44 and these constitute troughs 45 which are able to receive tines of a forklift. The height of each of the elongate elements 43, 44 is the same as the depth of each of the troughs 45.

Each of the wider elongate elements 44 are formed as tubular elements having a channel 46 extending longitudinally therethrough. The bottom of the subframe 41 is provided with three elongate parallel rectangular bars 47 which act as support feet. The support feet 47 serve to space the sheet 41 above a ground surface, but may be removed.

Although the pallet of Figures 5a and 5b shows channels 46 located side by side through the elongate elements 43, according to another embodiment, a single channel could be provided. Furthermore, the width of all of the elongate elements could be the same and all of the elongate elements could be provided with channels therethrough.

In use the pallet may be picked up by locating tines inside the channels 46. If it is desired to remove goods from the top surface of the pallet 40, then the tines can be located in the parallel troughs 45. The tines can then be raised and items removed from the pallet.

The pallet described above may be made from wood, metal, paper, fibreglass, or plastic and combinations of these and other materials . According to another embodiment of the present invention as shown in Figure 6 a support may have a wave like configuration 50, which could be similar to corrugations of corrugated iron. Peaks 51 would act to support items thereon and tines could be located in the troughs 52 located between the peaks 51 in order to remove items therefrom.

The support could be lifted by locating tines in channels 53 located directly below peaks 51.

Various embodiments of the invention have been described but it should be appreciated that the invention covers a broad concept used in storage and transportation of goods. The general concept of the invention described previously enables flexibility and adaptability for transportation and storage systems which has not previously been possible.
