550517 NEW ZEALAND PATENTS ACT, 1953 No: 550517 Date: 18 July 2007 COMPLETE SPECIFICATION LOADING AND UNLOADING APPARATUS AND METHOD We, SIvlARTBOX PROPERTY LIMITED, 13 Sultan Street, Ellerslie, Auckland, New Zealand, do hereby declare the invention for which we pray that a patent, may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: 5505^7 FIELD OF THE INVENTION The present invention relates to an apparatus and method for loading and unloading containers from a trailer.

The present invention also relates to a goods handling, cartage and storage method.

BACKGROUND Currently, goods storage services are commonly available and widely known. These services involve the offering of secure warehouse space by the service provider to users. Typically, die user or person wanting to make use of these services needs to transport the goods to be stored to the warehouse, and then secure them in storage means such as boxes, or locking them in garages at the warehouse facility. This method of offering storage services is inconvenient for the users, in that they may need to hire a suitable vehicle for the transportation of the goods, and in addition may be required to make a number of trips to be able to transport all of the goods. Further, all of the goods to be stored need to be handled twice in that they are firstly handled onto the trailer, and then secondly handled again to get them off the trailer and into the storage facility. The inconvenience of this process means that many users who would be inclined to put goods in storage may prefer to find storage space in their houses, garage or elsewhere.

DETAILED DESCRIPTION OF THE INVENTION With reference to the above drawings, a trailer according to a first aspect of the invention is generally indicated by the numeral 100, and a rolling rack according to a second aspect of the invention is generally indicated by the numeral 200.

According to the first aspect of the invention there is provided a trailer 100, suitable for being towed behind a vchicle (not shown) and for receiving a container 500, said trailer 100 comprising a trailer frame 110; a housing 120 adapted to enclose the container 500, 550^7 and supported by said trailer frame 110; and a pair of trailer roller-track arrangements 130 supported by said trailer frame 110. The trailer roller-track arrangements 130 extends from the rear edge of the trailer frame 110 and includes a plurality of rollers 140 aligned in a row to allow the container 500 to be rolled into and/or out of the housing 120.

It is envisaged that the housing 120 will extend substantially around the whole container 500, to provide protection from rain and the like. It is envisaged that the housing 120 will provide a snug fit over and around the container 500, to prevent it from being dislodged from the trailer roller-track arrangement 130 once loaded. The trailer 100 further includes a winching mechanism 150, for pulling the container 500 over the rollers 140, at the front of the trailer 100 to allow a container 500 to be rolled onto the trailer roller-track arrangement 130 from the rear of the trailer 100. The winching mechanism 150 is electrically operated in a preferred embodiment and is driven by electrical power from die towing vehicle (not shown). An inspection hatch 160 is provided in the front of the housing 120, to allow access to the container 500 through the housing 120.

The housing 120 further includes a lower loading door 170 at the rear of the trailer 100 to allow the container 500 to be loaded onto the trailer 100. The lower loading door 170 pivots between a closed position in which the container 500 cannot be loaded onto or off the trailer 100, and an open position (shown in figure 3) in which the lower loading door 170 acts as an access ramp to provide convenient loading access to the trailer 100. The lower loading door 170 is provided with access rollers 175 at the non-pivoting end of the door 170 to allow for movement of the trailer 100 when the upper loading door 170 is in the open position. The housing even further includes an upper loading door 171, whereby the upper loading door 17lis movable between a closed position in which the container 500 cannot be loaded onto or off the trailer 100, and an access position in which the upper loading door 171 pivots upward to provide an overhang for shelter against the weather.

In a preferred embodiment, the trailer 100 includes a set of telescopic stabilising feet 180 for stabilising the trailer 100 in a stationary condition to allow it to be loaded without tipping over. Further, the trailer 100 is provided with securing means in the form of a spigot pin (not shown) and complementary socket formation (not shown) to secure a container 500 onto the trailer roller-track arrangement 130 and prevent it from rolling off the trailer 100 when the trailer 100 is in motion.

With reference to the above drawings, a rolling rack according to a second aspect of the invention is generally indicated by the numeral 200. 5505^7 According to a second aspect of the invention there is provided a rolling rack 200, suitable for unloading a container 500 from a trailer I00, the trailer 100 having at least one row of container supporting rollers 140. The rolling rack 200 comprises a rack frame 210, and at least one rack roller-track arrangement 220 supported by said rack frame 210. The roller-track arrangement 220 comprises a plurality of rollers 230 extending from at least one edge of the rack frame and aligned in a row to allow a container 500 to be rolled onto and/or off the rolling rack 200. The rolling rack 200 further includes alignment formations 240 for aligning the rack roller-track arrangement 220 with complementary trailer roller-track arrangements 130 on the trailer 100.

In a preferred embodiment, the trailer 100 includes a guide formation in the form of a guide rail 190 adapted and configured to guide the container 500 along the rollers 140 during loading and/or stabilise the container 500 during transportation. The guide rail 190 has an overhanging lip (not shown) for engagement with complementary engagement formations (not shown) on the container 500.

In a preferred embodiment, the rolling rack 200 also includes a winching mechanism 250 for winching a container 500 onto the rack 200 over the rollers 230 of the rack roller-track arrangement 220. The winching mechanism 250 is located at the rear of the rolling rack 200 to allow a container 500 to be rolled onto the rollers 230 of the rack roller-track arrangement 220 at the front of the rolling rack 200.

It is envisaged that the rolling rack 200 will need to be moved around, and for this reason, the rolling rack 200 includes lifting formations 260 to allow the rolling rack 200 to be lifted b]^ a forklift (not shown).

As provided for in a fourth aspect of the invention, it is envisaged that the trailer 100 as defined above and the rolling rack 200 as defined above will cooperate as a system; whereby the rollers 230 of the rack roller-track arrangement 220 and the rollers 140 of the trailer roller-track arrangement 130 are at substantially the same height to allow for the convenient movement of a container 500 between the rack roller-track arrangement 220 and the trailer roller-track arrangement 130.

A method of loading a container between a trailer 100 and a rolling rack 200 is also provided as a fifth and sixth aspect of the invention. The method envisages providing a trailer 100 as defined above; as well providing a rolling rack 200 as defined above (with a container loaded onto it so that it is movable over the rack roller-track arrangement). The rack roller-track arrangement 220 on the rolling rack 200 is at the same height as the trailer roller-track arrangement 130 on the trailer 100. The rack roller-track arrangements 220 and 5505^ the trailer roller-track arrangements 130 are then aligned with each other by means of the alignment formations 240. At this stage, the container 500 may then be rolled over the rollers 140& 230 between the trailer 100 and the rack 200.

Alternatively, should more mechanical effort be required, the container 500 can be winched between the trailer 100 and the rack 200 by either of the winching mechanisms 150 or 260. This involves coupling the container 500 to the winching means 250 on the rack 200 to winch the container 500 from the trailer 100 to the rack 200 and winching it across, or coupling the container 500 to the winching means on the trailer 150 to winch the container from die rack 200 to the trailer 100.

It is envisaged that according to a fifth aspect of the invention, a method of providing a goods storage service may be provided using the apparatus provided. The goods storage service provider (not shown) will deliver a container 500 mounted onto the trailer 100 as defined above. The trailer 100 and container 500 will be left at a user's premises in order for the user to place goods to be stored inside the container at their convenience. During this time, the container will remain in the housing and be protected from any possible rain. In this way, the container may be composed of relatively cheap materia] such as wood, without having to waterproof the containers, which may be costly.

Once the user has finished placing goods mside the container, the trailer 100 is moved by the service provider to a container storage area, such as a warehouse (not shown). A rolling rack 200 is provided at the warehouse. The rolling rack 200 and the trailer 100 are aligned and the container 500 is offloaded. The container 500 may then be conveniently moved from the rack 200 and stored in an efficient stacked formation in the warehouse. In this way a forklift can approach the container 500 from the side, and not have to unload the container from the rear of the trailer 100 which would require longer forks and a larger size forklift. Accordingly, the size of the forklift required to offload the trailer 100 may be reduced. Further, efficient use is made of the available space at the warehouse.

It is envisaged that the user may be allowed access to their container 500 at the warehouse, when a small amount of goods are required to be retrieved by the user.

When the user requires the return of the stored goods, or after a predetermined period, the stacked container 500 is retrieved from the warehouse by a forklift, and loaded onto the rolling rack 200 from the side of the rolling rack 200. The container 500 is loaded onto a trailer 100 using the rolling rack 200, and then transported to the user's premises by means of the trailer 100. 5505^ It may be seen from the above explanation that only one forklift is required during the entire operation, since no forklift is used to unload the container 500 at the user's premises. Since the forklifts are potentially expensive pieces of equipment, the requirement of one forklift to sustain the entire goods storage service means low start-up costs for any service provider offering such goods storage services.

Further, no time is wasted by towing vehicles (not shown) and trailers 100 waiting for an available forklift to unload containers 500 from the trailer 100, which means that there is a greater availability and productivity of trailers 100. 5505^
