Improvements relating to stillages

Field of the invention

The present invention relates to stillages, and more specifically to support for stillages.

Background of the invention

Stillages are used to store or transport goods. They generally include a frame base and an additional structure, such as side or corner restraints, for supporting the goods. In one form, the base is rectangular with a support foot beneath each corner.

The presence of the feet gives rise to challenges in securely settling the stillage in a desired location, particularly if the stillage is to be supported at a location elevated from the ground. Some stillages are designed to be stackable, having a downward opening in the base of. each foot and upward protrusions on the top of the stillage which vertically align and cooperate with respective feet of an identical stillage placed thereupon. However, the bottom stillage in the stack must still rest on its feet, so is generally rested on a flat surface, such as flooring.

In some situations it may be desirable to settle a stillage on a pallet rack. Conventionally, a pallet rack is an open framework designed to support a pallet that has a flat bottom, rather than support feet. Such a pallet rack typically provides a support structure in the form of parallel elongated frame members, or bars, that are held in a horizontal plane, and on which a pallet may be rested. If a stillage is laid on the rack, with the feet of the stillage resting upon one or more of these parallel bars, the feet may easy be pushed off the bar by a lateral force, causing the stillage to topple. Therefore, it is desirable to provide an improved means to settle such a stillage on a pallet rack.

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 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.

Detailed description of the embodiments

An embodiment of an aspect of the invention is shown in Figure 1. A pallet rack 10 has a first pair of parallel elongate frame members 11 that commonly extend along an axis in a horizontal plane. The elongate frame members 11 span between and are supported at each end by respective vertical support frames 12. Each support frame 12 is comprised of a pair of parallel vertical beams 13 held together by cross members 13 A. The elongate frame members 11 are sized and spaced to securely support thereon at least one pallet. More commonly the elongate frame members 11 support multiple pallets, side-by-side. To support multiple generally square- based pallets, the length of the elongate frame members 11 is longer than the separation between the members so, viewed in plan, the support rack is an elongate rectangle.

The sizing and spacing of the elongate frame members 1 1 is generally tailored to support pallets of standardized dimensions, such as ISO standard pallet sizes 1219x1016mm (for North America), 1 165x1165mm (for Australia), 1100x1100mm (for Asia), 1000x1200mm (for Europe J

7 and Asia), and 800x1200mm (for Europe), and 1067x1067mm (for North America, Europe and Asia). In the example shown in Figure 1, the length of the pallet rack is more than three times its width, so that the rack can easily hold two or three standard pallets side-by-side.

To support additional pallets, the vertical support frames 12 also hold an (optional, but generally standard) second pair of horizontal elongate frame members 11 A, elevated above the first pair 11. The second pair 11A typically is between 100 centimetres and 200 centimetres above the first pair. Given tall enough support frames 12, further pairs of horizontal elongate frame members can similarly be spaced above the second pair 12. For convenience, the embodiment of the invention exemplified hereinafter is described only with reference to the first pair of elongate frame members 11. However, the second pair 11A and any further pairs of elongate frame members are substantially similar or identical to the first pair 11, so may simultaneously be configured or adapted to be used in the same manner as the first pair 11, as described hereinafter.

As shown in Figure 1, the elongate frame members 11 are adapted to support a stillage 14 thereon by having the stillage located onto four foot-locating members or devices 15 - two of the devices 15 being secured to each elongate frame member 11. Although only one stillage is illustrated in Figure 1, it is appreciated the elongate frame members 11 are sufficiently long to comfortably support two or three stillage racks side-by-side.

The stillage 14 is shown elevated from the pallet rack 10 in Figure 2. The stillage 14 is supported by four feet 16. The stillage has a flat, open rectangular frame 18, from which corner restraints 20 vertically extend. The feet 16 extend downwardly from the bottom of the corner restraints 20, beneath the frame 18.

The supported stillage 14 is sized such that its feet 16 rest on the parallel elongate frame members 11, and is stabilised on the rack 10 by having each foot 16 located on a corresponding foot-locating member 15.

The foot-locating members 15 are adjustably positioned along the elongate frame members 11 so that each foot-locating member 15 is aligned with a corresponding foot 16 of the stillage 14. The ability to adjustably position the foot-locating members 15 allows for accommodation of a variety of different sized stillages T4 on the pallet rack 10. J

Ideally, the foot-locating members 15 are capable of locking or restraining movement of the stillage 14 against any horizontal movement. In one embodiment, the restraining function can be provided by a single foot-locating member, and if the foot-locating member also locks the foot against rotational movement, then only a single foot-locating member is required to stabilise " the stillage.

Figure 3 provides an expanded view of circled region A in figure 2, showing a single in- situ foot-locating member 15. The foot-locating member 15 has a body portion 21 and an engagement portion 22, which is the top edge of the body portion 21. The stillage foot 16 is essentially a downwardly opening rectangular cup 30 (figure 4), or in other words, an open or hollow rectangular frustopyramid. The rectangular cup 30 is a frustopyramid in that it inwardly tapers towards the stillage until it forms a flat portion 31 in a horizontal plane. The flat portion 31 rests on the engagement portion 22 of the foot-locating member 15. The engagement portion 22 includes four corners 24 that define a perimeter of a rectangular space 32. The four corners 24 engage with respective corners 28 within the rectangular cup 30. This engagement restrains the foot 16 against horizontal and rotational movement with respect to the engagement portion 22. The engagement portion 22 is raised above an under-surface 46 of the body portion 21, by a pair .of opposed walls 36, 38. At least a portion of the under-surface 46 rests upon a top surface 47 of the elongate frame member 11 so that any load borne by the engagement portion 22 is transferred to the top surface 47 of the elongate frame member. Commonly, the rectangular cup 30 has sides 33 (Figure 3) of equal dimension, so that the rectangular cup 30 is more specifically a square cup (i.e. it is an open frustum of square pyramid). In this case, a tight engagement between the foot 16 and engagement portion 22 is achieved by having the four corners 24 of the engagement portion 22 positioned such that rectangular space 32 is, more specifically, a square space (as shown in figure 5). The four corners 24 are also arranged to define the engagement portion 22 in a flat horizontal plane so that the engagement portion 22 rests flush against flat portion 31 within the cup 30. Each of the four comers 24 of the engagement portion 22 engage with a respective comer 28 in the cup 30.

The foot-locating member 15 can exist as a member of an assembly, or it may be a stand-alone device that is connected to any suitable pallet rack, for stabilising a stillage thereupon. Figure 5 shows, in plan view, the foot-locating member 15 as a stand-alone device. The rectangular space 32 is defined by wall portions 34 which have top edges along opposing J

9 sides of the perimeter of the rectangular space 32. The wall portions 34extend along the entire perimeter of rectangular space 32. Ideally, the wall portions 34 are arranged to align with vertical walls 37 (Figure 3) of the stillage's corner restraints 20 from which the feet 16 extend.

The wall portions 34 are upper portions of a first wall 36 (Figure 5), an opposed second wall 38, and third and fourth walls 44 that are perpendicular to the first wall 36 and second wall 38 to define a steel square tube 45, This square tube 45 forms the body portion 21 of the foot- locating device 15. It is appreciated that in other embodiments, rather than the body portion being a square tube 45, it may be a solid square block. As shown in Figure 5, the first wall 36 and the opposing second wall 38, along the perimeter of the rectangular space 32, are parallel to two side members 40 and 42 of the foot-locating member or device 15. In this embodiment, the side members 40, 42 are similar flat metal plates, eg of steel. The first side plate 40 is welded to the first wall 36 and extends along the axis of the square tube 45 beyond the bottom surface 46 (Figures 4 and 6) of the tube 45 to allow for positioning of the first side plate 40 adjacent to and abutting a lateral wall 48 of elongate frame member 11. The first side plate 40 extends beyond the under surface 50 of the elongate frame member 11. The second side plate 42 is positioned parallel and opposite the first side plate 40 to abut against lateral wall 52, opposite the other lateral wall 48 of the elongate frame member 11. The first side plate 40 and second side plate 42 are joined a pair of fasteners in the form of bolts 54 (Figure 4) respectively above and beneath the elongate frame member 11. With this arrangement, the foot-locating device 15 straddles around the elongate frame member 11.

Each bolt 54 is secured into a threaded passage 56 that is lateral to the second side plate 42. The threaded passage 56 may be a nut that is independent from, or rigidly secured to, the second side plate 42. When the bolts 54 are untightened, the foot-locating device 15 can be adjustably positioned along the elongate frame member 11 by sliding the foot-locating device along the member. Once the foot-locating member 15 has been slidably adjusted into position (of which there are an infinite number) along the elongate frame member 11, the position is secured by tightening the bolts 54 into their corresponding nuts 56, thereby pressing the side plates 40, 42 toward each other, clamping the elongate frame member 11 therebetween. After clamping, the engagement portion 22 is upwardly directed to engage with the downwardly directed cup 30 of a stillage foot 16. J

10

This clamping action allows the foot-locating member 15 to be accommodate for a variety of elongate frame member 11 widths, wherein the maximum width that can be accommodated is determined by the maximum separation between of the first side plate 40 and second side plate 42. The maximum height of the elongate frame member 11 is essentially determined by the separation of the bolts 54.

In an alternative embodiment, as shown in Figures 7 and 8, side members 40a and 42a of foot-locating device 15a heed not extend beyond the under surface 50 of the elongate frame member 11. Threaded passages in the form of nuts 58 are rigidly secured to side member 40a at holes 60 in the side member. A grub screw 62 is screwed into each hole 60 to clamp the second side member 42a against lateral wall 52a of the elongate frame member 11.

In a further embodiment, as shown in Figure 9, the square tube 45b, which forms the body portion 21b of the foot-locating device 15b, is secured to the elongate frame member 11 on a top surface 64 of the frame member 11. The bottom of square tube 45b has flanges 66. Each flange 66 has a hole 68 through which a fastener is inserted, the fastener extending into the top surface 64 of the elongate frame member 11.

In some embodiments of the invention, one or both of the side members, used in clamping the foot-locating member 15d to the elongate frame member 11, may be formed from folded sheet metal, as illustrated in Figures 10 to 13 A. In the embodiment illustrated in Figure 10, the body portion 21d is welded onto a strip 80 of sheet steel. The strip 80 has an under- surface 46d that rests on the elongate frame member 11. The strip is folded away from the body portion, at locations 81 laterally flanking the body portion, to form a first side member 40d and a second side member 42d. The second side member 42b has nuts 70 on an internal surface of the side member 42d. By fastening grub screws 71 through the nuts 70 and against the elongate frame member 11, the foot-locating member 15d is laterally clamped between the inward facing tips of the grub screws 71 and the first side member 40d.

The side members 40d and 42d are inwardly folded at respective ends 82, 83 to form U- channels 84 that sit beneath the elongate frame member 11. A bottom plate 85 fits between the side members 40d, 42d, and has downwardly bent ends that slot into the U-channels 84. Like side member 42d, the bottom plate 85 has a nut 86 on an internal surface. A grub screw 87 is J

1 1 fastened through nut 86 and pushes against the bottom of the elongate frame member 11 to vertically clamp the foot^locating member 15d to the elongate frame member.

Although, as described hereinbefore, the body portion 21 has been embodied by the same square tube 45, alternative constructions of the body portion may be used instead of the square tube construction. In Figures 11 , the body portion 21 e is formed with the same sheet steel strip 80e that forms clamping side members 40e, 42e. At the respective tops of each side member 40e, 42e, the strip 80e bends inwardly by 90 degrees to define an under-surface of body portion 21e, for resting on the elongate from member 11. The strip 80e also bends upwardly, away from the under-surface 46e, to define a neck portion 85e of the body member 21e, though which a screw and nut combination can be used to squeeze the neck 85e and, by association, side members 40e, 42e together to laterally clamp the body portion 21e to the elongate frame member 11. From the neck 85e, the strip 80e bulges outwardly and then upwardly to form upper vertical walls 36e, 38e. Each upper vertical wall has a top edge 87e, each edge having opposed corners 24e (Figure 11 A) which define the perimeter of a rectangular space filled by a top wall 86e. The corners 24e, thus define an engagement portion 22e that fits within a downwardly extending cup on the foot of a stillage, as in the embodiments hereinbefore described.

Similarly to the embodiment of Figure 10, a bottom plate 85e is fitted beneath the elongate frame member by engaging in U-channels 84e at bottom ends of the side members 40e, 42e, and a screw and nut combination may be used to provide vertical clamping. In contrast with the embodiment of Figure 10, the U-channels 84e are formed by outward (rather than inward) bends of the respective side members 40e, 42e.

In the embodiment illustrated in Figure 12, the body portion 21f of foot-locating member 15f has a wall vertical 36f that is coplanar with the side wall 46f that is adjacent the foot-locating member. From wall 36f, strip 80f is bent to form a square loop 88f that includes top surface 86f, a second vertical wall 38f and a lower wall having an under-surface 46f. It will be appreciated that the engagement portion 22f is formed in the same manner as in the embodiment of Figures 11 and 11 A. A separate side member 42f is fastened to the strip 80f to laterally clamp the foot- locating member to the elongate frame member.

In the embodiment illustrated in Figure 13, the body portion 21 g is constructed from two separate folded steel metal strips 80g' and 80g". Each strip has an inward loop that respectively t

12 contributes, to the body portion 21g, an outer vertical wall 36g, 38g, a top wall portion 86g', 86g", an inner wall 90g', 90g" and a bottom wall having an under-surface portion 46g', 46g". The two strips 80g' and 80g" are held together by upper and lower screw/nut combinations, 91g and 92g, respectively. As illustrated in Figure 13A, vertical wall 38g has a hole 93g in it to allow access to the screw head of the screw/nut combination 91 g. Similar to the other embodiments described herein, vertical walls 36g and 38g each have upper edges that define corners 24g of an engagement portion 22g for fitting within a rectangular cup of a stallage foot.

In an alternative embodiment (not shown), the engagement portion is formed by the respective corners of two opposing walls, wherein the walls are joined by a central transverse wall to form an I or H shaped structure in plan view. Alternatively, a body portion may be constructed in which there are no wall portions along any sides of the rectangular space. Instead, the four corners that define a rectangular space are by ends corners of diagonal walls which are crossed to create an X structure in plan view.

In another embodiment (not shown), the engagement portion of the device 15 of Figure 3 is arranged to have the rectangular space 32 rotated 45°, about a vertical axis. In this way, the four corners 24 engage with centre points 35 along sidewalls 33 of the rectangular cup 30. The four corners 24 may be joined by rectangular walls along the perimeter, or in an I, H or X structure as previously described.

In one arrangement (not shown), the cup 30 may be a circular (frustoconical) cup, and each of the four corners 24 of the engagement portion 22 engage with a respective

circumferential point in the cup 30. Alternatively, the four corners 24 are included in a circumferential wall of a circular tube. The four "corners" in this case refer only to an imaginary square space within the circumference. The corners 24 are separated from each other by 90°, measured from the centre of the tube. Such an arrangement, will prevent horizontal translation of the stallage foot 16, but will not prevent rotation of the foot if only a single foot-locating member 15 of this embodiment is used. Therefore, to prevent rotation of the stallage 14, at least two such foot-locating members 15 would be required in this case.

Ideally the stallage that is placed on the pallet rack is dimensioned so that each foot 16 of the stallage rests on an elongate member 11 of the pallet rack. However, alignment requires the depth of the stallage to be essentially the same as the spacing of the parallel elongate frame 1

13 members 11. Therefore, depending on the relative dimensions of the particular stillage and pallet rack, it may not be possible to align all four feet of the stillage with the pallet rack. To • accommodate stillages of different depths, pairs of stillage feet may be located onto respective pairs of foot-locating members, wherein each foot-locating member is adjustable in position along a cross-bar that is supported by the elongate frame members of the stillage rack. As illustrated in Figure 14, two stillage feet-locating apparatuses 100 traverse the elongate frame members 11. Each feet-locating apparatus 100 includes two foot-locating devices 15b, as described hereinbefore, clamped to a rigid metallic support member or elongate cross-bar 102. The foot-locating members 15b are adjustably spaced along the cross-bar 102 so that their separation corresponds with the separation of the respective feet with which they are intended to engage.

In the embodiment illustrated in Figure 14, the foot-locating member 15b is the same as the foot-locating member of Figure 9. However, it is appreciated that in other corresponding embodiments of the invention any of the other foot-locating members described herein may be used.

It is also appreciated that in some environments specific stillages will be favoured over other stillages. A storage facility may, for example, only use one (or a few) types of stillage. Thus it may be that, rather than having adjustability, it is sufficient to have a feet locating apparatus that has multiple foot-locating members in fixed locations on the apparatus. In such cases foot-locating members may be fixed to or even integrally formed on cross-bar 102. The foot- locating device 15 may be supplied with a stillage 14, the device and stillage forming a stillage kit. This is advantageous in that it allows the provision of a foot-locating device which is designed for an optimal locking arrangement for a particular stillage 14.

The optimal locking arrangement can also be realised when supplying the foot-locating device 15 separately from the stillage 14. This may be achieved by designing the foot-locating device for use with a stillage of known dimensions or a stillage having a foot 16 with a downwardly directed cup 30 of particular known dimensions. This may be achieved by producing a device 15 in accordance with a method in which a body portion 21 is formed having an engagement portion 22, wherein the engagement portion 22 is in accordance with a predefined specification. The method also includes a step of providing in the device 15 a means for securing the body portion 21 to a pallet rack 10. The predefined specification for the engagement portion is designed so that the engagement portion 22 is fittable within a cup 30 of stillage 14, the cup having dimensions that have been factored into the predefined specification.
