An intermodal device comprising: a base; a perimetric rectangular frame; the frame comprising a first rail mounted to the base, a second rail in spaced relation to the first rail and a plurality of posts connecting the first and second rail; the posts being pivotally mounted to the first rail and in sliding engagement with the second rail; wherein the posts are arranged to slide along the second rail from a position at right angles to the first and second rails to a position parallel to the rails, the frame arranged to move from an expanded position to a collapsed position as a result of the movement of the posts.
The invention relates to intermodal devices and systems including the modular arrangement of components for both standardization and customization of goods for transportation.
BACKGROUNDIn order to meet the economic criteria for the efficient transport of cargo, the associated intermodal devices must be standardized in size and shape. For large and bulk cargo, 20 ft and 40 ft containers are examples of standardisation, whereby shipping, trucks, cranes etc have all been developed around these standardized intermodal devices.
Whilst shipping containers are well suited for large cargo and bulk materials, the transport of smaller and/or more fragile are less well catered for. It follows that the smaller the component, the greater the variety in size ands shape. To this end, the principles of standardization are less easily attained.
It would therefore be advantageous if systems to provide for the standardization of such cargo.

The invention, and its various aspects, relates to intermodal assemblies which meet the criteria of standardizing the conveyance of cargo whilst also being customizable to suit the requirements of different manufacturers in different industries. Whilst the intermodal assemblies according to the present invention are highly applicable to a range of different industries, those industries having direct and identifiable application for the intermodal assemblies include the transport of automotive and aviation components. It is also applicable to the electronics industry for both components as well as appliances. Further still, the intermodal assemblies are well suited for the transport of fruit and other grocery items.
In all cases the ability to customize to a particular size, and then standardize the intermodal assemblies for the customized size of cargo is a significant advantage conferred by the invention. The customized and standardized sizes may be subject to application and industry. For instance, for the transportation of apples the articles may be 75 mm in diameter, and so the tray may be arranged to carry 48 apples in an array of 8 by 6. With tolerance, the tray may measure 640 mm by 480 mm.
For larger articles, the size may not be the controlling issue, with weight of the overall tray being the guide. For instance, where the legislative requirements of a country limit the weight of an item to, say, 27 kg the trays including the articles may be limited to that weight which would control the number of articles to be carried by the ray; the dividing assembly may then be adjusted to accommodate apertures for that number of articles.
In various embodiments of the present invention, the base, and possibly the entire tray, may be injection moulded. In this case, forms of reinforcement may be added to the base to enhance strength. For instance, ribs along various portions may be added to increase flexural or shear force capacity of the base.
With reference to features associated with the articles being transported, an elastomeric sheet (such as neoprene) may be added to the base and/or to the panels of the dividing assembly, so as to provide a friction surface to mitigate movement of the contained articles or provide cushioning against impact damage. For the transport of fruit, the base may include a plurality of holes so as to provide ventilation to the contained fruit.
In a fifth aspect, the invention provides an intermodal device comprising: a base; a perimetric rectangular frame; the frame comprising a first rail mounted to the base, a second rail in spaced relation to the first rail and a plurality of posts connecting the first and second rail; the posts being pivotally mounted to the first rail and in sliding engagement with the second rail; wherein the posts are arranged to slide along the second rail to a position parallel to the rails, the frame arranged to move from an expanded position to a collapsed position as a result of the movement of the posts.
In a sixth aspect, the invention provides an intermodal device comprising: a rectangular base; four walls arranged around the periphery of the base; each of said walls in pivotal engagement, so as to selectively fold inwards into a space defined by said walls.
In a seventh aspect, the invention provides a dividing assembly for an intermodal device, the dividing assembly comprising: a plurality of dividers, said dividers cooperatively assemblable to form the dividing assembly and selectively disassemblable; each of said dividers being collapsible, such that in the assembled form the dividing assembly is arranged to move from an expanded position to a collapsed position.
It will be convenient to further describe the present invention with respect to the accompanying drawings that illustrate possible arrangements of the invention. Other arrangements of the invention are possible and consequently, the particularity of the accompanying drawings is not to be understood as superseding the generality of the preceding description of the invention.
A first embodiment of the present invention is shown in
Considering firstly the intermodal assembly 5, Figures to 3, 4A, 4B, 5A and 5B shows a standard container unit 10 houses a plurality of trays 20 all of which are size to fit within the container unit 10. Within each tray is a dividing assembly 15 defining an array of recesses for receiving articles for transport, as seen in
The dividing assembly comprises a pair of end panels 40 connected by a series of articulated panels 30. Each articulated panel including a plurality of hinges spaced from each other so as to allow the articulated panel to retract in a concertina fashion. Parallel to the end panels 40 are dividing panels 35. When assembled, and in an extended position with the end panels distal from each other, each of the recesses is arranged to receive product for transport to an end user. The assembly is subsequently sent back to the supplier of the intermodal device for re-use with the transport of a different cargo or range of articles. Alternatively, the intermodal device, including the trays and dividing assemblies may be sold to a supplier of the articles, and so in this instance the various components may be returned accordingly.
The spacing of the hinges is such so as to position a hinge from each articulated panel within each recess. It will be appreciated that the hinge may be a weakened portion of the panel, a portion of the panel having been shaped to fold more readily than other portions of the panel or a pinned assembly. To achieve this, the dividing assembly 15 is retracted so as to be collapsible along the articulated panels 30 so as to close each of the recesses into a package with the end panels brought into proximity to each other, with the entire dividing assembly not significantly larger than the two end panels 40. As shown in
The trays 20 comprise sheets stamped with a pattern so as to form a tray shape having unitary perimeter walls. Consequently on returning the intermodal assembly to the origin, each tray can be flattened into its original single sheet by dis-assembling the tray into its constituent flat sheet. An example of such a flat sheet 120, 125 can be seen in
Together with the load carrying capacity of the walls 47, the trays in various embodiments displayed collectively or individually, other features. For instance, in a further embodiment, a tray for the intermodal assembly may include projections 45 which engage with trays stacked above so as to prevent or hinder lateral movement of said trays. The trays may further include handles 50 to facilitate loading and unloading. Alternatively, the trays may receive attachable handles, such as rope handles.
The various components of the intermodal assembly according to this embodiment may be manufactured from a range of different materials. Given the lower load bearing capacity of this embodiment, the trays and various parts of the dividing assembly may comprise extruded propylene sheet or closed cell board, such as that commonly referred to as “corriboard”. In the latter case, the benefit of increased flexural strength whilst reducing overall weight may add further advantage.
A second embodiment of the intermodal assembly is shown in
In this embodiment the walls 75 include a slidable panel 95 which slides relative to connecting panels 90 to aid in the lifting of the tray 60 and to extend the height of the tray.
In a further embodiment, the base plate 65 includes elastic straps 105 which are arranged to stretch and engage distally placed recesses 110 which are shaped to engage the elastic strap 105. This has the advantage of tying down objects as shown in
The tray 60 of this embodiment is also arranged to receive the dividing assemblies as previously described. Whereas the trays 15 of the first embodiment may be more suitable for smaller or lighter components, the heavier base plate 65 of this embodiment is more suited to heavier components and for instance may be suitable for the automotive or aviation industries where individual components may weigh several kilograms. In a further embodiment, the tray 60 may have a carrying capacity of up to 300 kg. By placing the dividing assemblies onto the base plate as the dividing assembly is non-structural all of the mass of the cargo is supporting by the stackable trays 60.
With reference to the stackability of the trays 60 as shown in
In a further embodiment, the base plates may include laterally positioned engagement portions, such as interconnecting lugs and recesses, so as to join multiple base plates into a single larger base plate.
It will further be appreciated that more than two tray sheets can be joined to form a single tray. In an alternative embodiment, four sheets may be joined end to end and side by side to form a single tray twice the length and twice the width of any of the individual trays.

To facilitate the tracking requirements for the intermodal device 260, a panel 285 includes a portion to fit an RFID tag. It will be appreciated that the panel 285 may receive the RFID in an adhesive engagement. Alternatively, the RFID tag may be permanently sealed to the panel 285. It will further be appreciated that the panel 285 may include other means of identification including bar codes, QR codes, powered RFID, GPS and other media both scannable and emitting. In its basic form the frame according to the present invention may include only a top rail, bottom rail and a pair of posts at each corner.
Returning to
The posts 335 at each corner in the fully extended position of
To prevent premature collapse of the frame, the posts 335 may be selectively locked in place by a locking device. Various methods of locking may be achieved including a spring loaded pin located proximate to the respective post. Alternatively, if the various rails are biased to the extended position by a spring or similar in the frame, then the posts 335 may consequently be biased to a vertical position. Further still, the slotted hole 332 may have an extended recess which engages the posts 335 in the vertical position.
The locking arrangement as shown in
In concept, the dividing assembly according to the present invention may comprise a plurality of dividers, with each divider cooperatively assemblable with the other dividers to form the dividing assembly. The dividers are also selectively disassemblable, and so for a return journey carrying freight of one type, the dividers may be assembled into an array of a certain shape. On the return leg, the dividers may be disassembled, and re-assembled to form a dividing assembly of a very different configuration to accommodate freight of a different size.
Importantly, each of the dividers are collapsible (such as telescopic). In the assembled form, the dividing assembly is arranged to move from an expanded position to a collapsed position.
The female divider 365 includes a plurality of female connectors 400, 405 in a ridge on the upper edge of the divider to engage with a plurality of male connectors. The female divider 365 further includes intermediate female connectors 415, similar to that of the male divider 360 for accommodating non-standard arrays to receive non-standard sized freight.
A further adaptation of the intermodal device according to the present invention is the ability to expand the carrying capacity of the intermodal device in a modular fashion.
