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

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.
An embodiment of an aspect of the invention is shown in
The sizing and spacing of the elongate frame members 11 is generally tailored to support pallets of standardized dimensions, such as ISO standard pallet sizes 1219×1016 mm (for North America), 1165×1165 mm (for Australia), 1100×1100 mm (for Asia), 1000×1200 mm (for Europe and Asia), and 800×1200 mm (for Europe), and 1067×1067 mm (for North America, Europe and Asia). In the example shown in
To support additional pallets, the vertical support frames 12 also hold an (optional, but generally standard) second pair of horizontal elongate frame members 11A, 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
The stillage 14 is shown elevated from the pallet rack 10 in
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 14 on the pallet rack 10.
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.
Commonly, the rectangular cup 30 has sides 33 (
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.
The wall portions 34 are upper portions of a first wall 36 (
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.
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
In a further embodiment, as shown in
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
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 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
Similarly to the embodiment of
In the embodiment illustrated in
In the embodiment illustrated in
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
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 stillage 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 stillage 14, at least two such foot-locating members 15 would be required in this case.
Ideally the stillage that is placed on the pallet rack is dimensioned so that each foot 16 of the stillage rests on an elongate member 11 of the pallet rack. However, alignment requires the 30, depth of the stillage to be essentially the same as the spacing of the parallel elongate frame 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
In the embodiment illustrated in
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.
It will be understood that the invention disclosed and defined in this specification extends 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.
