Description

P/00/01 1 Regulation 3 2 AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Invention Title: Improved assembly for display of articles The following statement is a full description of this invention, including the best method of performing it known to us: 2 Improved stillage for transport and display of articles This application is to be treated as a patent of addition to Australian patent application number 2007291892. Field of the invention 5 The present invention relates to a device for transporting and displaying articles. In particular, the present invention relates to an improved stillage for efficient transporting of articles and use as a display means for displaying articles. Background of the invention Stillages are generally used for transportation and storage of items that are not capable of .0 being stacked for transportation upon a pallet. Such items include but are not limited to plants in pots. It is primarily for use in transporting awkward and movable items and therefore a stillage for practical purposes includes side panels for enclosing items to be stored on a base section. Stillages generally comprise a framework having a base with upwardly extending support legs fixably located at corner regions of the base and interconnected by non-displaceable cross .5 members. Articles to be stored or transported by the stillage, rest on the base and are located between and retained by the upwardly extending support legs and cross-members. One disadvantage of such stillages is that when the transported articles are removed, an empty stillage occupies considerable space, which is not only wasteful but proves costly when the stillages are being returned for reuse. 20 A further drawback of known stillages is that there is generally a practical limitation on the number of stillages that can be transported. Also different sized articles are not easily accommodated by known stillages without adversely decreasing the effective use of transport space. It is an object of the present invention to address and ameliorate at least one of the above 25 mentioned disadvantages or at least provide a useful alternative. It is a further object of the present invention to provide a stillage which more efficiently utilizes transport space and which can accommodate a range of different sized articles.

3 It is an even further object of the invention to provide a transport means which can also be used to display articles post-transport. Reference to any prior art in the specification is not, and should not be taken as, an acknowledgment or any form of suggestion that this prior art forms part of the common general 5 knowledge in Australia or any other jurisdiction or that this prior art could reasonably be expected to be ascertained, understood and regarded as relevant by a person skilled in the art. Summary of the invention The present invention is an modification of the invention defined in Australian patent application number 2007291892, which is directed to an improved stackable stillage system for [0 transport of articles of different sizes from an originating point to a destination point, and display of said articles at the destination point, the system including: at least a first and second stillage in a stackable array, the at least first and second stillage including: a base frame including a generally planar platform for receiving an article or [5 plurality of articles thereon; at least four spaced apart support legs, each having a foot, said support legs connected to the base frame for supporting the platform of the base frame, wherein the support legs are shaped for releasably receiving a height adjustment element, and wherein the foot of each support leg includes a bulbous structure 20 with a recessed under portion having an outwardly expanding cavity to the open bottom; a side frame mounted on the base frame or the support legs and forming a retaining wall about at least a portion of the platform for retaining article(s) thereon; and 25 a plurality of releasable height adjustment elements of differing lengths, the height adjustment elements including a connecting head extending above the side frame, wherein the connecting head is shaped to receive the under portion of the foot of the second stillage thereabove in engaged relation in a stackable condition; 4 wherein the distance between the at least first and second platform in a stackable condition is adjustable by the selectively chosen height adjustment elements with a particular length to allow accommodation for a range of different sized articles between the at least first and second platforms of the at least first and second stillages during 5 transport; and wherein the height adjustment elements are further separately adjustable by substituting with first and second different length sets of height adjustment elements to allow angular positioning of the second stillage relative to the first stillage so that articles can be displayed on the angled platform of the second stillage for display at the destination 0 point. The modification is directed to the addition of removable height adjustable sidewalls. Accordingly, the present invention provides a stackable stillage system for transport of articles of different sizes from an originating point to a destination point, the system including: at least a first and second stillage in a stackable array, the at least first and second stillage 5 including: a base frame including a generally planar platform for receiving an article or plurality of articles thereon; at least four spaced apart support legs, each having a foot, said support legs connected to the base frame for supporting the platform of the base frame, 20 wherein the support legs are shaped for releasably receiving a height adjustment element, and wherein the foot of each support leg includes a bulbous structure with a recessed under portion having an outwardly expanding cavity to the open bottom; a side frame mounted on the base frame or the support legs and forming a 25 retaining wall about at least a portion of the platform for retaining article(s) thereon; and a plurality of releasable height adjustment elements of differing lengths, the height adjustment elements including a connecting head extending above the side frame, wherein the connecting head is shaped to receive the under portion of the foot of the 5 second stillage thereabove in engaged relation in a stackable condition, and wherein the height adjustment elements include a plurality of spaced apart apertures; wherein the distance between the at least first and second platform in a stackable condition is adjustable by the selectively chosen height adjustment elements with a 5 particular length to allow accommodation for a range of different sized articles between the at least first and second platforms of the at least first and second stillages during transport; wherein the height adjustment elements are further separately adjustable by substituting with first and second different length sets of height adjustment elements to allow angular 10 positioning of the second stillage relative to the first stillage so that articles can be displayed on the angled platform of the second stillage for display at the destination point; and a plurality of sidewalls of differing heights and including formations for releasable engagement with the apertures of the height adjustment elements; wherein the stillage is reconfigurable to a stillage with sidewalls by the insertion of height 15 adjustment elements of selected heights and the connection of removable sidewalls of selected heights to form a stillage with sidewalls. The apertures are preferably keyhole shaped and may be provided as horizontally aligned pairs of apertures on the two perpendicular sides of the height adjustment elements. The apertures are preferably evenly spaced, with the spacing aligning on height adjustment elements 20 of differing heights. The formations are preferably hooks that are inserted by aligning with corresponding apertures and pushing the formations into the apertures before lowering the sidewall, whereby the sidewalls hang off the hooks. The sidewalls are preferably removable from the outside of the stillage when the stillage is in a stacked condition. 25 Advantageously, each sidewall includes two formations on each end, one located towards the top of the sidewall and one located towards the bottom. Preferably, a first sidewall is provided with a first height, which corresponds to the first height of a first height adjustment element; a second sidewall is provided with a second height, which corresponds to the second height of a second height adjustment element, the second height 30 may be twice the first height, such that two first sidewalls can be connected to form a wall on the second height adjustment element; a third sidewall is provided with a third height, which corresponds to the third height of a third height adjustment element, the third height may be three 6 times the first height, such that three first sidewalls can be connected to form a wall on the third height adjustment element. An even number of spaced apertures is typically provided, such as two apertures vertically spaced along the height of the first height adjustment element, four apertures vertically 5 spaced along the height of the second height adjustment element and six apertures vertically spaced along the height of the third height adjustment element. Where multiple sidewalls are used to create a wall of the stillage, any one sidewall can be removed or omitted while the other sidewalls are in place, with each being separately connected independently of the others. .0 Advantageously, a bag can be used to line a stillage reconfigured with sidewalls. Further aspects of the present invention and further embodiments of the aspects described in the preceding paragraphs will become apparent from the following description, given by way of example and with reference to the accompanying drawings.

Detailed description of the embodiments Referring to the drawings there is shown in Figure 1 an improved stackable stillage system for transport and display of articles including a plurality of stillages 11, 12, 13, 14. [5 However the substantial benefit of the system is in its use of a plurality of releasable height adjustment elements 51. The stillages 11, 12, 13, 14 shown in Figure 1 for transport and display of articles include a base frame 21 of generally rectangular configuration having a planar central platform 23 comprising a wire mesh type structure. The base frame also includes a peripheral side edge 22 on 20 which the platform is mounted. As shown in this embodiment, the base frame 21 of the bottom stillage 14 is supported off the ground, by support legs 31 located at each corner of the rectangular base frame. The base frame 21 is further strengthened by cross-members 26 connecting between support legs 31 and forming uppermost portion of the side frame 24. Therefore the side frame 24 of the stillage 25 includes substantially vertical members 25 extending between peripheral side edge 22 and uppermost cross-members 26.

9 The support legs 31 include a central portion having an upper end forming a connecting head 32 and a lower end where there is formed a bulbous foot 29, which has an internal recess (not shown). As shown in Figure 1, the foot 29 contacts the ground and stabilises the stillage system during transport and display of articles. Further the spacing and strength of the base 5 frame allows ready transporting by forklift or the like. As shown in detail in Figure 2 the stillage includes a connecting head 32 mounted on the base frame or the support legs and extending above the side frame 24 and able to engage and be enveloped by the corresponding foot 29 of a second stillage in a stackable array as shown in detail in Figure 2. The internal recess of the foot 29 (not shown) is shaped to stably receive the 0 upper end of the support leg forming the connecting head 32 of a neighbouring stillage to form a stable stack of stillages. Referring to Figures 4 and 5, there is shown a closer view of upper end of the support leg 31 forming the connecting head 32 and having an 'L' -shaped cross-section. Spaced along its length are two spaced apart substantially "L"-shaped sleeve members 35, 36 forming sleeve for 5 receiving a height adjustable element 51 in sliding relation with the support leg. Thereby each of the connecting heads 32 is shaped to receive a corresponding height adjustment element which in turn is adapted to engage the foot of a second stillage in a stackable array, wherein the distance and angle between one platform of one stillage and a platform of an adjacent stillage in a stack of stillages can be adjusted to provide accommodation for a range of different sized articles in the 20 stack and to angle at least one of the stillages by utilising two sets of height adjustment elements of differing lengths for display of articles in the stillages following transport of said stillages. The height adjustment element 51 is shown in detail Figures 6 and 7. In this embodiment the height adjustment element consists of a lower portion 52 of corresponding cross section to the openings of the sleeve member 35, 36. The height adjustment element 51 includes a tongue 25 53 appended to the lower portion 52 and protruding and extending towards along the height adjustment element 51 to its lowest end. In use the tongue slides into engagement around outside of the upper sleeve member 36 and therefore must be suitably spaced from the lowest end of the height adjustment element 51 to allow engagement of the lower end 52 of the height adjustment element 51 through both sleeve members 35, 36. The tongue provides dual function of precisely 30 limiting the depth of a height adjustment element and maintaining close engagement of the L shaped lower section and the L-shaped connecting head of the support leg for structural strength.

10 Thereby height adjustment element 51 is stably housed within the spaced apart sleeve members 35, 36 in an abutting relation with the support leg. As shown in Figure 9 the adjustment elements 51 may be selectively chosen with particular length to space a stillage above a second stillage to allow holding of articles of height 5 requiring such spacing. However for transport as in Figure 1 the height adjustment elements 51 can be removed for more compact transport after use. However as shown in Figures 10 and 11 a further substantial advantage is achieved by substituting with a separate height adjustment elements of differing length. The height adjustment element has a shaped cross section which is received by a second .0 stillage in a stackable array, wherein the distance and angle between one platform and its neighbouring platform in a stack of stillages can be adjusted to provide accommodation for a range of different sized articles in the stack and display said articles. Referring to Figures 9, 10 and 11, there is illustrated an array of stillages mounted on top of each other or one stillage is able to be disposed at an angle to another. The advantage of this [5 arrangement is that space between adjacent stillages in an array can be adjusted to hold a range of different sized articles during transport. A further advantage is that once the articles have reached their destination, the array of stillages can be further adjusted to angle one platform relative to another. In this way articles, which have been transported can then be displayed professionally by reconfiguring the array of stillages after reaching a destination. 20 It can be seen by particularly Figures 10 and 11 that the shape of the foot of each support leg includes a bulbous structure with a recessed under portion is an important feature that allows stable stacking of one stillage on top of another but particularly allows angular stacking relative to each other. It is the recessed under portion having outwardly expanding cavity to the open bottom for receiving an upper portion of the height adjustment element of an adjacent stillage in 25 an array that tends it to a central position and thereby a stable configuration regardless of the different heights. Clearly practical limitations apply due to tipping of the articles in the stillage. However within such practical limitations this configuration of engagement provides a stable system.

11 Figures 12 through 27 illustrate the modified stillage system the subject of the present application. It has been found that the stillage the subject of the earlier application can be further extended in design for usage as a stillage with adjustable sides. A sided stillage has many diverse applications in the Intermediate Bulk Container (IBC) market, and are used by a range of diverse 5 industries, such as fruit and vegetable growers, farmers, frozen vegetables, and processed food producers. An IBC, when lined with food grade approved liners ensure the product arrives clean, fresh, safe and with a minimum spoilage. Sided stillages are also required for industries including automotive, aeronautical, plastic manufacturers and postal and parcel services. The existing stillage system can therefore be modified as required by the use of [0 customized height extension elements 151 (see Figures 15, 16 and 17) that are provided in a variety of heights, with a plurality of spaced apart keyhole shaped apertures 155. The apertures 155 are provided in pairs aligned horizontally on the two perpendicular sides 156, 157 of the angle iron that forms the extension elements. The pairs of apertures 155 are spaced along the length of the height adjustment elements 151 at a set dimension, this dimension being carried 15 through to height adjustment elements 151 of different lengths such that the apertures align. The lower portion 152 of the height adjustment elements 151 include tongues 153 that are capable of being used with standard stillages 11, by slotting into sleeve members 35, 36 on the support legs 31. The modified height adjustment elements 151, 161, 171 allow for the stillage system to 20 be used in the same ways as described in the original application, but may also be adapted to include one or more sidewalls 160, 162, 164. The heights of the sidewalls 160 correspond to the heights of the height adjustment elements 151. Each sidewall is made from a mesh construction having a plurality of spaced apart vertical wires 172 and a plurality of spaced apart horizontal wires 173. Each sidewall includes upper and lower formations 174, 175 at each end, such that 25 each sidewall includes four formations. The formations are illustrated in the form of hooks, with a connection pin 176, an inward projecting portion 177 and a downward projection 178 (see Figure 14), which create a hook. The upper formation 174 is located close to the top edge 179 of the sidewall, whilst the lower formation 175 is located towards the bottom edge 180, but spaced above it. The spacing of the lower formation 175 is so that it can align with the lower aperture 30 155 of the height adjustment elements, see Figures 15 to 17, which illustrates that the position of the lowermost aperture is above the overlapping portion of the lower portion 152. The bottom edge 180 sits just above the upper cross-members 26 of the stillage 11 (see Figure 20).

12 The apertures 155 are keyhole shaped, such that they have an upper wider portion 181 and a lower narrower portion 182 (see Figure 17). The sidewalls are connected (see Figure 20) by aligning the formations 174, 175 with the corresponding wider portion 181 of apertures 155 and pushing the inward projecting portion 177 and downward projection 178 into the aperture. 5 The sidewall 160 is then lowered, whereby the inward projecting portion 177 engages in the narrower portion 182 of the aperture and the downward projection 178 prevents the sidewall from being pulled outwards. The sidewalls 160 hang off the hook created by the inward projecting portion 177 and the downward projection 178. To remove the sidewalls 160, it must first be lifted up and then pulled outwardly. This connection arrangement allows the sidewalls to [0 be individually removed from the outside of the stillage, even when in a stacked configuration, allowing access to the goods inside. It also means that one sidewall can be removed independently of any other sidewall. As shown in Figure 12 to 14 and Figures 15 to 17, the sidewalls 160, 162, 164 and the height adjustment elements 151, 161, 171 are provided in varying heights. A first sidewall 160 is 15 provided with a first height, such as 295-300mm, which corresponds with a first height adjustment element 151 having a first height of 300mm from the its connecting head 132 to the bottom 133 of its upper portion. A second sidewall 162 is provided with a second height, such as 595-600mm, which correspond with a second height adjustment element 161 having a second height of 600mm, being twice the height of the first height. As shown in Figures 21 and 24, this !0 allows for either a second sidewall 162 to be used with the second height adjustment element 161, or two first sidewalls 160 can be used, as four apertures 155 are provided. Similarly, a third sidewall 164 is provided with a third height, such as 895-900mm, which corresponds with a third height adjustment element 171 having a third height of 900mm, being three times the first height. As shown in Figures 25 and 27, this allows for either a third sidewall 164 to be used with the 25 third height adjustment element 171, or three first sidewalls 160 can be used, as six apertures 155 are provided. Additional heights may be provided, but typically these are of similar dimensional spacing, with each height adjustment element being a multiple of the first height. Where multiple sidewalls 160 are used to create a wall of the stillage, any one sidewall 160 can be removed or omitted while the other sidewalls are in place, as each are separately 30 connected independently of the others. This allows a lower 160c or middle 160b sidewall in the example of Figure 27 to be removed whilst the uppermost sidewall 160a is still connected. It is also possible for one wall of the stillage to be omitted, such that sidewalls are only connected on 13 three sides, allowing full access to any one side of the stillage. Where all four walls include sidewalls, as shown in Figures 19, 22 and 26, a bag can be used to line the reconfigured stillage for use with such things as consumable food goods. The components are preferably made from galvanised steel, such that they are washable and rust free, so suitable for the food industry. 5 After use of the stillage with sidewalls, each sidewall can be removed and the height adjustment elements removed to convert it back to a compact stillage 11 as per the original invention, such that it can be stacked as per Figure 1 for return transport. A stillage with removable sidewalls according to the present invention is particularly attractive to seasonal or batch production industries where the stillage can be reconfigured to L0 their collapsed modular form for storage and reconfigured with sidewalls easily on-site as demand for products are required. The reverse logistics costs of return to the primary producer or parts provider provide for considerable savings over fixed dimension Intermediate Bulk Containers (IBC). It will be understood that the invention disclosed and defined in this specification extends [5 to all alternative combinations of two or more of the individual features mentioned or evident from the text or drawings. All of these different combinations constitute various alternative aspects of the invention.
