Description

FIELD

[0001] The invention generally relates to packing systems for products, and particularly, to packing systems having a particular application to the packing of elongate articles used in the construction and building industry, such as aluminum extrusions for window and / or doors assemblies, pipes, or other elongated building elements.BACKGROUND

[0002] For storage and transportation of large elongate articles of plastics or metals, such as pipes or aluminum extrusions for window and / door assemblies, it is typical to bundle the articles together and locate them on a wooden pallet or the like. In some instances, the articles are placed within an elongated box prior to being placed on the pallet.

[0003] In some instances, strapping or the like is wrapped around the bundles or the box, but this requires sufficient clearance, and furthermore, there can be limitations to how tightly the strapping can be secured. This can mean that there is some potential for movement of the bundled articles during transit. Furthermore, the strapping needs to be cut once the bundle has arrived at its destination and is ready to be unpacked. This means that the strapping, which is often made of a plastic-based material, goes to waste.

[0004] In other instances, U-shaped frame members are assembled from lengths of wood that are nailed or screwed together and then mounted to the pallet in order to constrain the articles being stored / transported. There are disadvantages to this manner of packing large elongate articles, such as aluminum extrusions and the like.

[0005] The frame members are usually time consuming to mount to the pallet and often require the bundle to be restrained during installation. Similarly, it takes time to disassemble and remove the frame members in order to unload the bundle from the pallet when it reaches its destination. Another issue with this type of packing system is the need to pad out any spaces between the bundled articles in order to ensure there is minimal slippage or movement of the individual articles during transit. This can also be time consuming to attend to.

[0006] Depending on the integrity of the construction of the frame members, they may be prone to becoming loose or otherwise weakened during transit. This can lead to undesirable movement of the articles being transported.

[0007] An additional problem with the use of conventional pallets and frame members is that they are not practical for reuse once they have arrived at their destination, which may, for example, be a building or construction site. The amount of material used, and the size of the pallets, are prohibitive to their return to their place of origin, and as such, there is limited ability to recycle the materials used. Instead, they are often placed with other undesired materials on the site for later disposal.

[0008] There are known alternatives to this method of storage and transportation of elongate articles. For example, PCT Publication No. WO2018 / 045408 generally discusses a packaging assembly for use in the transport of bundles of products, such as plastic and metal extrusions.

[0009] The assembly includes respective upper and lower cleats linked or otherwise connected with side supports. The articles to be transported are loaded into a plurality of such packaging assemblies prior to the installation of the upper cleat. The side supports are adjustable in height, which can help in minimizing any extra packing materials that need to be added in order to pad out the spaces between the articles. However, this packaging assembly is still not easy to reuse and recycle due to the number of constituent parts. Accordingly, an improved and / or alternative approach to medication management may be beneficial.SUMMARY

[0038] Some embodiments pertain to packing systems having a particular application to the packing of elongate articles used in the construction and building industry, such as aluminum extrusions for window and / or doors assemblies, pipes, or other elongated building elements.Packing System in Use

[0039] The packing of elongate building elements such as aluminum extrusions, generally indicated by E, used in the construction of window and door assemblies in buildings, for transport from their point of origin, e.g., a manufacturing or storage facility, is shown in FIGS. 1 and 2, the latter being a close up view of the area indicated by A in FIG. 1.

[0040] It should be noted that while reference is made in this description to the elongate building elements being aluminum extrusions, embodiments may be used to pack other building elements and materials. For example, some embodiments of the invention have ready application for the packing of guttering and downpipes, as used in the drainage system of a building, for lengths of timber, or the like.

[0041] Such extrusions typically have a regularly formed cross-sectional profile, such as L-shaped profiles or rectangular box section, or the like. As best seen in FIG. 2, the extrusions are bundled together in a manner conducive to efficient packing. This may be done manually by workers placing, stacking, and interlocking the various extrusions accordingly, but may also be achieved in an automatic process as the extrusions are discharged from the extrusion plant.

[0042] When packing the extrusions, they are placed into a box B of cardboard or lightweight rigid plastic sheets or the like. To maximize the capacity of the box, the extrusions are usually packed in an efficient and regular way. As the extrusions are stacked upon each other, there is an increasing risk that their contents may shift as the box is moved or otherwise transported.

[0043] To restrain the extrusions within the box B during transit, the packing system of in this embodiment, generally indicated by 100, provides a plurality of securing brackets 102 at regular intervals along the length of the box.

[0044] The packing system 100 also includes a pair of rails 104, which are received within the securing brackets and support the bottom of the box B. These rails are formed from a suitably durable and robust material, for example, a metal or metal alloy, such as aluminum. In the illustrated example, the rails are extrusions of hollow rectangular box section profiles, sufficiently engineered to support the weight of the box when loaded. However, in some embodiments not shown here, the rails may be lengths of timber with the desired cross-sectional profile.

[0045] The brackets contact and support the sides of the box, while also allowing a clamping or bearing force to be applied to the top side of the box or directly to the uppermost extrusions themselves. This acts to restrain or otherwise limit the movement of the contents of the box.Packing System Components

[0046] An example of a single securing bracket 102 of an embodiment of the present invention is shown in an assembled form in FIG. 3 and in an exploded view in FIG. 4. The securing bracket 102 includes a base portion 106 to which two uprights 108 are mounted, at their lower ends 108a, to the base portion via an axle pin 110 held in place with a fastener 112. These uprights can be moved between a vertical condition to a horizontal condition, and this pivotal movement is allowed by virtue of the presence of the axle pin and fastener.

[0047] The upper ends 108b of the uprights 108 co-operate, through the use of a fastening member 114, with a top portion 116. The top portion may be tightened to the uprights, thereby clamping down on the top of the box (not shown in FIGS. 3 and 4) through the action of the fastening member, which itself is held in place within the uprights via a hinging body 114a. The head 114b of the fastening member bears down on a reinforcing plate 118 provided to the top portion. The collective base portion 102, uprights 108, and top portion 116 form an internal space S in which the box (not shown in FIGS. 3 and 4) may be located in use.

[0048] Each of these components will now be discussed in greater detail, beginning with the base 106 shown in FIG. 5. In some embodiments, the base may be molded from a suitably robust plastics material, including, without limitation, original or recycled HDPE and / or PP. Depending on the loads to be transported, medium densities of HDPE or PP may be preferred. However, other plastics materials may be used, including, but not limited to, glass filled and / or fiber filled nylon, etc., as will be readily appreciated by a person skilled in the art.

[0049] As can be seen, the base portion 106 has, in plan view, a substantially rectangular profile. A pair of shallow recesses 120 are provided to the top surface 122 proximate the respective ends 124 of the base portion. In use, these recesses receive the rails (not shown in this view but 104 in FIGS. 1 and 2). The relative depth of the recesses is such that when the rails are in place, the upper surfaces of the same are substantially in the same plane as the top surface at the center of the base portion. As such, when in use, the rails and the top surface of the base portion provide a substantially flat, near continuous contact surface for the box (not shown in this view but B in FIGS. 1 and 2). The respective ends 124 of the base portion 106 are configured to receive the uprights (108 in FIG. 3) in such a way that when the uprights are connected, only pivotal movement towards the center of the base portion is permitted.

[0050] In the illustrated embodiment, this is achieved by the presence of flanges 126 extending upwards from the respective ends. The flanges are dimensioned to terminate above the axis of rotation defined by the axle pin (110 in FIG. 4), such that the uprights (108 in FIG. 3) can only pivot inwards towards the center of the base portion 106, i.e., through an arc of about 90°, the respective ends of the arc defined by the flange and the upper surface of the base portion.

[0051] As can been seen, the flanges 126 extend around the corner of the base portion 106 to form a lip 128 on either side. This contacts the side of the uprights (108 in FIG. 3) in use. The lips include an aperture 130 therethrough that, in use, receives the pin axle (110 in FIG. 4) about which the uprights are mounted to same.

[0052] Disposed between the lips 128 of each flange 126 is a rib 132 centrally located on the inner face of the flange. This interlocks with the upright (108 in FIG. 3) for additional structural integrity, providing an additional contact surface for the pin axle (110 in FIG. 4) connecting the uprights to the base portion 106.

[0053] The relative height of the flange 126 and lips 128, and the position of the apertures 130 passing through same, is such that when the uprights (108 in FIG. 3) are in a horizontal condition, as per FIG. 11 (discussed further below), the top of the flange is higher than the plane defined by the uppermost surfaces of the uprights in this position. This leaves a small, recessed area that, in use, receives at least a part of the respective ends of the top portion (116 in FIG. 3) of the bracket. Furthermore, it should be noted from FIG. 11 that the flange forms a support or bearing surface, on which a successive base portion may sit. This is helpful when storing multiple brackets since they may be stacked on top of each other as shown in FIG. 12.

[0054] Turning now to FIGS. 6A and 6B, these show an example of one of the uprights 108 of the bracket, showing the outer side (FIG. 6A) and the inner side (FIG. 6B) respectively. Similar to the base portion, the upright may be formed as a molding of a suitably robust plastics material, including, without limitation, original or recycled HDPE and / or PP. Depending on the loads to be transported, medium densities of HDPE or PP may be preferred. However, other plastics materials may be used, including reinforced nylon or the like, as will be readily appreciated by a person skilled in the art.

[0055] The upright 108 has a lower end 108a, which is connected to the base portion (not shown) via an axle pin (not shown), and an upper end 108b which engages with the top portion (not shown) of the bracket. The lower end 108a is configured with a vertically orientated slot 134 along its center line. In use, when the upright is mated with the appropriate flange of the base portion shown in FIG. 5, the rib (132 in FIG. 5) is received within this slot. This helps act to guide and control the relative movement of the upright 108 as it moves from a vertical condition to a horizontal condition. This movement is about the horizontal axis defined by the aperture 136 passing through the lower end that receives the axle pin (not shown in FIGS. 6A and 6B).

[0056] As best seen in FIGS. 6A and 6C, the upper end 108b of the upright 108 is configured with a vertically orientated slot 138 along its center line extending and opening onto the top surface. In use, this receives the fastening member 114 of the upright.

[0057] Referring back to FIG. 4, it will be seen that the fastening member 114 includes a shaft 114c with a head 114b provided to one end. The shaft passes through a hinging body 114a, essentially a metal rod through which an aperture is provided to receive the shaft. In the illustrated embodiment, the aperture through the hinging body 114a is threaded. As such, rotation of the shaft 114c moves it forward and backwards relative to the hinging body. However, in some embodiments not shown here, the other end of the shaft may instead be received in a threaded aperture provided to the bottom of the vertically orientated slot (142 in FIG. 6A).

[0058] As will be appreciated in FIGS. 6A to 6C, when the fastening member is in place, the hinging body 114a is disposed within the square recess 140 provided to the upper portion 108b of the upright 108. The slot 138, being open along its length, provides clearance for the shaft 114c as the fastening member 114 pivots from a vertical orientation, as shown in FIG. 6C (when the top portion, 116 in FIG. 3, is being clamped in position), to a horizontal configuration (required to place or remove the top portion in use).

[0059] If desired, a tool may be used in the head 114b of the fastening member 114 to advance or retreat the shaft relative to the hinging body 114a so as to either bear down on the top portion (116 in FIG. 3) or create sufficient clearance to allow the head to be pivoted out of the way to facilitate removal of the top portion. It will be seen that the recess 140 in which the hinging body is disposed is dimensioned such to allow some vertical travel. When the fastening member is tightened to secure the top portion to the uprights 108, the hinging body bears against the upper side of the recess.

[0060] When the fastening member 114 is loosened, this increases the distance between the head 114b and the hinging body 114a, providing some clearance to allow the hinging body, and therefore the fastening member, to be moved vertically and pivoted through an arc of 90° (or more) to a substantially horizontal position such that the top portion (116 in FIG. 3) can be removed. This arrangement also ensures the hinging body remains confined to the recess 140 of the upper portion 108b of the upright.

[0061] In FIGS. 6A to 6C, it will be seen that the upper end 142 of the upright 108 also includes a pair of protrusions 142. In use, these key into complementary recesses provided to the underside of the top portion (116 in FIG. 3). This can assist in providing a positive fit when assembling the bracket.

[0062] As best seen in FIG. 6A, rather than being formed as a solid molding of plastics material, the outer face of the upright 108 is formed as a lattice or honeycomb structure. This provides some structural integrity and strength to the upright. The inner face, seen in FIGS. 6B and 6C, which in use contacts the box in which the articles to be packed are placed, and is substantially flat and smooth. This is to ensure a consistent contact surface with the box. The relative depth or thickness of the upright 108 is such that when in a collapsed configuration, as shown in FIG. 11, the outer faces are in a plane that is lower than the plane defined by the upper edges of the flanges 126 provided to the respective ends of the base portion 106 of the packing system 100, i.e., the upper edges of the flanges are higher than the uprights when the latter are laid flat.

[0063] Referring now to FIG. 7, this shows the top portion 116 of the bracket. As with the base portion and uprights, this may be formed as a molding of a suitably robust plastics material, including, without limitation, original or recycled HDPE and / or PP. Like the uprights, the top portion 116 has an outer face that is formed as a lattice or honeycomb structure, conferring rigidity and strength. The reverse side, not visible in this view, substantially flat and smooth, for a consistent contact surface with the articles or box being transported when the packing system is being used.

[0064] At the respective ends 146 of the outer face of the top portion 116 is provided a slot 148 and a bearing surface 150. As shown in FIG. 8, when the top portion is in use, the slot is in alignment with the vertically orientated slot 142 of the upright 108. The slot 148 of the top portion 116 receives the shaft 114c of the fastening member 114 of the upright 108, while the head 114b of the fastening member may, once the shaft has been sufficiently threaded through the hinging member 114a, contact and bear down the bearing surface 150. The bearing surface may be reinforced with a plate 118 including a metal, such as aluminum, stainless steel, or another suitably durable material. The use of this plate may help distribute the force exerted by the head as it bears down on the top portion, preventing or limiting any damage to the bearing surface through the plastics material used to form the same.

[0065] As seen in FIGS. 7 and 8, the end 146 of the top portion 116 is configured with a pair of protrusions 152. Referring to FIG. 5, in use, these protrusions interlock with complementary recesses provided to the interior surfaces of the flange 126 of the base portion 106. This may help with providing a positive keying-in effect when nesting the respective top portion to the base portion, as will be apparent from the following discussion.

[0066] An alternative embodiment of the upright 108 is shown in FIG. 9. In this embodiment the fastening member 114 is secured in place via the hinging body 114a. In contrast to the previously described embodiment, the hinging body is unable to slide along the recess 140 (the reverse side being shown here) in which it is disposed and is only able to pivot relative to the upright. As a consequence, the slot 138 provided for the fastening member need only substantially approximate the latter's length dimension. To retain the hinging body within the recess, a couple of protrusions (not visible) may be provided about the open face of same (not visible).

[0067] Additionally, in this embodiment, the head 114b of the fastening member 114 may be a separate component in the form of a nut, which is threaded onto the upper end of the fastening member. In this manner the top portion 116 is clamped to the upright 108. This configuration allows for a larger head for the fastening member, potentially allowing for the use of fingers to operate the embodiment rather than an Allen key or the like as may be the case with the embodiment of FIG. 8, for example.

[0068] FIG. 10 shows a variant of the base portion 106 and support rail 104. In this embodiment, the support rail, e.g., an extrusion of aluminum, is configured with flanges 104a that key into corresponding cutouts 120a provided to the recess 120 that receives the support rail in use. This is advantageous in that it better retains the support rail with the base portion in a positive fit, making it more difficult to accidentally separate the respective components. As will be appreciated, this configuration requires the support rail to be slid into the base portion rather than simply being dropped in from above.

[0069] Referring now back to FIGS. 1 to 4, it will be appreciated that the configuration of the bracket 102 of packing system 100 allows for its top portion 116 to be added and removed, and the uprights to be folded up and down, for assembly / disassembly of the bracket as needed. For example, when being used to transport a load of extrusions E, the user determines the number of brackets 102 required to ensure adequate support of the box B that will be used to contain and transport the extrusions (two brackets in the example of FIG. 1). The uprights 108 of each bracket are pivoted into a vertical position relative to the base portion 106. Rails 104 (only visible in FIGS. 1 and 2) are then placed into the appropriate recesses (120 of FIG. 5) for same. Screws or similar fastening members may be passed through the rails and into the base portion to secure the former to the latter.

[0070] In this assembled configuration, but prior to the addition of the top portion 116, the bracket 102 forms a substantially open U-shaped structure into which the box may be placed. Extrusions are loaded into the box until it has reached its capacity. The top portion 116 is then mated with the upper ends of the uprights, and the fastening members 114 articulated to advance the head of same relative to the top portion.

[0071] By this manner, the top portion 116 is effectively clamped against the uprights 108 and the box (not shown) being transported, which in turn is supported by the base portion 106. This provides a means for securing the box for transport. In some instances, a packer material, such as sheets of cardboard or fabrics may be placed across the upper surfaces of the box to help fill in any clearance and optimize the clamping effect.

[0072] Returning to FIG. 7, it will be noted that the top portion 116 has, in plan view, a substantially rectangular profile, similar to that of the base portion (106 in FIG. 5). However, dimensionally, it is a little smaller than the base portion. This means that when the components of the bracket 102 are in a collapsed configuration, as shown in FIG. 11, the top portion 116 fits within the footprint of the base portion 106 in a nested fashion, its underside contacting the outer sides of the uprights 108. The protrusions 152 of the top portion key into the flange 126 of the base portion. As previously noted, the plane defined by the outer sides of the uprights when collapsed is lower than that defined by the respective upper edges of the flanges. This creates a partial recess into which the top portion sits.

[0073] Similarly, the underside of the base portion 106, not visible in FIG. 11, includes a recessed portion that is substantially complementary to the perimeter of the top portion 116. As previously noted, this means that multiple brackets 102 to 102111 may be stacked or otherwise nested upon each other when the uprights 108 and top portion 116 are in the collapsed configuration, as shown in FIG. 12. This may be useful for transport of the brackets back to the point of origin, or for storage when not being used, either prior to return to point of origin or afterwards.

[0074] As shown in FIG. 13, this same nesting functionality is also present when the brackets 102 are assembled and may be used to stack successive boxes B to B111 extrusions. As each successive bracket interlocks or nests with the preceding bracket, this provides some resistance to lateral shifting of the upper boxes, and thus potentially greater stability during transport.

[0075] The brackets 102, and the rails 104, may similarly be nested when not in use, as shown in FIG. 14. This may be storage purposes or for transport back to the place of origin.

[0076] It will be apparent in FIG. 14 that each rail is a separate elongate component and is only linked to the opposing rail through the use of the bracket. As such, it will be understood that the brackets act as cross members, supporting the weight of the box being transported across the width dimension of same.

[0077] However, in some embodiments not illustrated here, rather than the rails 104 being separate components held in fixed relationship to each other by virtue of their engagement with the brackets 102, they may be connected with cross members of hollow rectangular box section profiles. These cross members may be welded or otherwise secured to the respective rails to form a structure similar to a ladder. This may be useful in providing support additional to that provided by the brackets, if required, across the width dimension of the box when it is loaded.

[0078] It should also be noted that a mixture of loaded units (boxes, brackets and rails) and collapsed units (brackets and rails) may also be nested for transport. This may be useful for returning loads to the point of origin; some boxes may be loaded with materials for transport.

[0079] The packing system as herein described is advantageous as it greatly facilitates reuse of its brackets and rails, and as such leads to less wastage of components which may otherwise go to landfill. Furthermore, being primary comprised of plastics material, any damaged components may be recycled.

[0080] Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise”, “comprising”, and the like, are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense, that is to say, in the sense of “including, but not limited to”.

Embodiment Construction

[0038]Some embodiments pertain to packing systems having a particular application to the packing of elongate articles used in the construction and building industry, such as aluminum extrusions for window and / or doors assemblies, pipes, or other elongated building elements.

Packing System in Use

[0039]The packing of elongate building elements such as aluminum extrusions, generally indicated by E, used in the construction of window and door assemblies in buildings, for transport from their point of origin, e.g., a manufacturing or storage facility, is shown in FIGS. 1 and 2, the latter being a close up view of the area indicated by A in FIG. 1.

[0040]It should be noted that while reference is made in this description to the elongate building elements being aluminum extrusions, embodiments may be used to pack other building elements and materials. For example, some embodiments of the invention have ready application for the packing of guttering and downpipes, as used in the drainage syst...

FIELD

[0001] The invention generally relates to packing systems for products, and particularly, to packing systems having a particular application to the packing of elongate articles used in the construction and building industry, such as aluminum extrusions for window and / or doors assemblies, pipes, or other elongated building elements.BACKGROUND

[0002] For storage and transportation of large elongate articles of plastics or metals, such as pipes or aluminum extrusions for window and / door assemblies, it is typical to bundle the articles together and locate them on a wooden pallet or the like. In some instances, the articles are placed within an elongated box prior to being placed on the pallet.

[0003] In some instances, strapping or the like is wrapped around the bundles or the box, but this requires sufficient clearance, and furthermore, there can be limitations to how tightly the strapping can be secured. This can mean that there is some potential for movement of the bundled articles during transit. Furthermore, the strapping needs to be cut once the bundle has arrived at its destination and is ready to be unpacked. This means that the strapping, which is often made of a plastic-based material, goes to waste.

[0004] In other instances, U-shaped frame members are assembled from lengths of wood that are nailed or screwed together and then mounted to the pallet in order to constrain the articles being stored / transported. There are disadvantages to this manner of packing large elongate articles, such as aluminum extrusions and the like.

[0005] The frame members are usually time consuming to mount to the pallet and often require the bundle to be restrained during installation. Similarly, it takes time to disassemble and remove the frame members in order to unload the bundle from the pallet when it reaches its destination. Another issue with this type of packing system is the need to pad out any spaces between the bundled articles in order to ensure there is minimal slippage or movement of the individual articles during transit. This can also be time consuming to attend to.

[0006] Depending on the integrity of the construction of the frame members, they may be prone to becoming loose or otherwise weakened during transit. This can lead to undesirable movement of the articles being transported.

[0007] An additional problem with the use of conventional pallets and frame members is that they are not practical for reuse once they have arrived at their destination, which may, for example, be a building or construction site. The amount of material used, and the size of the pallets, are prohibitive to their return to their place of origin, and as such, there is limited ability to recycle the materials used. Instead, they are often placed with other undesired materials on the site for later disposal.

[0008] There are known alternatives to this method of storage and transportation of elongate articles. For example, PCT Publication No. WO2018 / 045408 generally discusses a packaging assembly for use in the transport of bundles of products, such as plastic and metal extrusions.

[0009] The assembly includes respective upper and lower cleats linked or otherwise connected with side supports. The articles to be transported are loaded into a plurality of such packaging assemblies prior to the installation of the upper cleat. The side supports are adjustable in height, which can help in minimizing any extra packing materials that need to be added in order to pad out the spaces between the articles. However, this packaging assembly is still not easy to reuse and recycle due to the number of constituent parts. Accordingly, an improved and / or alternative approach to medication management may be beneficial.SUMMARY

[0010] Certain embodiments of the present invention may provide solutions to the problems and needs in the art that have not yet been fully identified, appreciated, or solved by current packing technologies, and / or an alternative solution thereto.

[0038] Some embodiments pertain to packing systems having a particular application to the packing of elongate articles used in the construction and building industry, such as aluminum extrusions for window and / or doors assemblies, pipes, or other elongated building elements.Packing System in Use

[0039] The packing of elongate building elements such as aluminum extrusions, generally indicated by E, used in the construction of window and door assemblies in buildings, for transport from their point of origin, e.g., a manufacturing or storage facility, is shown in FIGS. 1 and 2, the latter being a close up view of the area indicated by A in FIG. 1.

[0040] It should be noted that while reference is made in this description to the elongate building elements being aluminum extrusions, embodiments may be used to pack other building elements and materials. For example, some embodiments of the invention have ready application for the packing of guttering and downpipes, as used in the drainage system of a building, for lengths of timber, or the like.

[0041] Such extrusions typically have a regularly formed cross-sectional profile, such as L-shaped profiles or rectangular box section, or the like. As best seen in FIG. 2, the extrusions are bundled together in a manner conducive to efficient packing. This may be done manually by workers placing, stacking, and interlocking the various extrusions accordingly, but may also be achieved in an automatic process as the extrusions are discharged from the extrusion plant.

[0042] When packing the extrusions, they are placed into a box B of cardboard or lightweight rigid plastic sheets or the like. To maximize the capacity of the box, the extrusions are usually packed in an efficient and regular way. As the extrusions are stacked upon each other, there is an increasing risk that their contents may shift as the box is moved or otherwise transported.

[0043] To restrain the extrusions within the box B during transit, the packing system of in this embodiment, generally indicated by 100, provides a plurality of securing brackets 102 at regular intervals along the length of the box.

[0044] The packing system 100 also includes a pair of rails 104, which are received within the securing brackets and support the bottom of the box B. These rails are formed from a suitably durable and robust material, for example, a metal or metal alloy, such as aluminum. In the illustrated example, the rails are extrusions of hollow rectangular box section profiles, sufficiently engineered to support the weight of the box when loaded. However, in some embodiments not shown here, the rails may be lengths of timber with the desired cross-sectional profile.

[0045] The brackets contact and support the sides of the box, while also allowing a clamping or bearing force to be applied to the top side of the box or directly to the uppermost extrusions themselves. This acts to restrain or otherwise limit the movement of the contents of the box.Packing System Components

[0046] An example of a single securing bracket 102 of an embodiment of the present invention is shown in an assembled form in FIG. 3 and in an exploded view in FIG. 4. The securing bracket 102 includes a base portion 106 to which two uprights 108 are mounted, at their lower ends 108a, to the base portion via an axle pin 110 held in place with a fastener 112. These uprights can be moved between a vertical condition to a horizontal condition, and this pivotal movement is allowed by virtue of the presence of the axle pin and fastener.

[0047] The upper ends 108b of the uprights 108 co-operate, through the use of a fastening member 114, with a top portion 116. The top portion may be tightened to the uprights, thereby clamping down on the top of the box (not shown in FIGS. 3 and 4) through the action of the fastening member, which itself is held in place within the uprights via a hinging body 114a. The head 114b of the fastening member bears down on a reinforcing plate 118 provided to the top portion. The collective base portion 102, uprights 108, and top portion 116 form an internal space S in which the box (not shown in FIGS. 3 and 4) may be located in use.

[0048] Each of these components will now be discussed in greater detail, beginning with the base 106 shown in FIG. 5. In some embodiments, the base may be molded from a suitably robust plastics material, including, without limitation, original or recycled HDPE and / or PP. Depending on the loads to be transported, medium densities of HDPE or PP may be preferred. However, other plastics materials may be used, including, but not limited to, glass filled and / or fiber filled nylon, etc., as will be readily appreciated by a person skilled in the art.

[0049] As can be seen, the base portion 106 has, in plan view, a substantially rectangular profile. A pair of shallow recesses 120 are provided to the top surface 122 proximate the respective ends 124 of the base portion. In use, these recesses receive the rails (not shown in this view but 104 in FIGS. 1 and 2). The relative depth of the recesses is such that when the rails are in place, the upper surfaces of the same are substantially in the same plane as the top surface at the center of the base portion. As such, when in use, the rails and the top surface of the base portion provide a substantially flat, near continuous contact surface for the box (not shown in this view but B in FIGS. 1 and 2). The respective ends 124 of the base portion 106 are configured to receive the uprights (108 in FIG. 3) in such a way that when the uprights are connected, only pivotal movement towards the center of the base portion is permitted.

[0050] In the illustrated embodiment, this is achieved by the presence of flanges 126 extending upwards from the respective ends. The flanges are dimensioned to terminate above the axis of rotation defined by the axle pin (110 in FIG. 4), such that the uprights (108 in FIG. 3) can only pivot inwards towards the center of the base portion 106, i.e., through an arc of about 90°, the respective ends of the arc defined by the flange and the upper surface of the base portion.

[0051] As can been seen, the flanges 126 extend around the corner of the base portion 106 to form a lip 128 on either side. This contacts the side of the uprights (108 in FIG. 3) in use. The lips include an aperture 130 therethrough that, in use, receives the pin axle (110 in FIG. 4) about which the uprights are mounted to same.

[0052] Disposed between the lips 128 of each flange 126 is a rib 132 centrally located on the inner face of the flange. This interlocks with the upright (108 in FIG. 3) for additional structural integrity, providing an additional contact surface for the pin axle (110 in FIG. 4) connecting the uprights to the base portion 106.

[0053] The relative height of the flange 126 and lips 128, and the position of the apertures 130 passing through same, is such that when the uprights (108 in FIG. 3) are in a horizontal condition, as per FIG. 11 (discussed further below), the top of the flange is higher than the plane defined by the uppermost surfaces of the uprights in this position. This leaves a small, recessed area that, in use, receives at least a part of the respective ends of the top portion (116 in FIG. 3) of the bracket. Furthermore, it should be noted from FIG. 11 that the flange forms a support or bearing surface, on which a successive base portion may sit. This is helpful when storing multiple brackets since they may be stacked on top of each other as shown in FIG. 12.

[0054] Turning now to FIGS. 6A and 6B, these show an example of one of the uprights 108 of the bracket, showing the outer side (FIG. 6A) and the inner side (FIG. 6B) respectively. Similar to the base portion, the upright may be formed as a molding of a suitably robust plastics material, including, without limitation, original or recycled HDPE and / or PP. Depending on the loads to be transported, medium densities of HDPE or PP may be preferred. However, other plastics materials may be used, including reinforced nylon or the like, as will be readily appreciated by a person skilled in the art.

[0055] The upright 108 has a lower end 108a, which is connected to the base portion (not shown) via an axle pin (not shown), and an upper end 108b which engages with the top portion (not shown) of the bracket. The lower end 108a is configured with a vertically orientated slot 134 along its center line. In use, when the upright is mated with the appropriate flange of the base portion shown in FIG. 5, the rib (132 in FIG. 5) is received within this slot. This helps act to guide and control the relative movement of the upright 108 as it moves from a vertical condition to a horizontal condition. This movement is about the horizontal axis defined by the aperture 136 passing through the lower end that receives the axle pin (not shown in FIGS. 6A and 6B).

[0056] As best seen in FIGS. 6A and 6C, the upper end 108b of the upright 108 is configured with a vertically orientated slot 138 along its center line extending and opening onto the top surface. In use, this receives the fastening member 114 of the upright.

[0057] Referring back to FIG. 4, it will be seen that the fastening member 114 includes a shaft 114c with a head 114b provided to one end. The shaft passes through a hinging body 114a, essentially a metal rod through which an aperture is provided to receive the shaft. In the illustrated embodiment, the aperture through the hinging body 114a is threaded. As such, rotation of the shaft 114c moves it forward and backwards relative to the hinging body. However, in some embodiments not shown here, the other end of the shaft may instead be received in a threaded aperture provided to the bottom of the vertically orientated slot (142 in FIG. 6A).

[0058] As will be appreciated in FIGS. 6A to 6C, when the fastening member is in place, the hinging body 114a is disposed within the square recess 140 provided to the upper portion 108b of the upright 108. The slot 138, being open along its length, provides clearance for the shaft 114c as the fastening member 114 pivots from a vertical orientation, as shown in FIG. 6C (when the top portion, 116 in FIG. 3, is being clamped in position), to a horizontal configuration (required to place or remove the top portion in use).

[0059] If desired, a tool may be used in the head 114b of the fastening member 114 to advance or retreat the shaft relative to the hinging body 114a so as to either bear down on the top portion (116 in FIG. 3) or create sufficient clearance to allow the head to be pivoted out of the way to facilitate removal of the top portion. It will be seen that the recess 140 in which the hinging body is disposed is dimensioned such to allow some vertical travel. When the fastening member is tightened to secure the top portion to the uprights 108, the hinging body bears against the upper side of the recess.

[0060] When the fastening member 114 is loosened, this increases the distance between the head 114b and the hinging body 114a, providing some clearance to allow the hinging body, and therefore the fastening member, to be moved vertically and pivoted through an arc of 90° (or more) to a substantially horizontal position such that the top portion (116 in FIG. 3) can be removed. This arrangement also ensures the hinging body remains confined to the recess 140 of the upper portion 108b of the upright.

[0061] In FIGS. 6A to 6C, it will be seen that the upper end 142 of the upright 108 also includes a pair of protrusions 142. In use, these key into complementary recesses provided to the underside of the top portion (116 in FIG. 3). This can assist in providing a positive fit when assembling the bracket.

[0062] As best seen in FIG. 6A, rather than being formed as a solid molding of plastics material, the outer face of the upright 108 is formed as a lattice or honeycomb structure. This provides some structural integrity and strength to the upright. The inner face, seen in FIGS. 6B and 6C, which in use contacts the box in which the articles to be packed are placed, and is substantially flat and smooth. This is to ensure a consistent contact surface with the box. The relative depth or thickness of the upright 108 is such that when in a collapsed configuration, as shown in FIG. 11, the outer faces are in a plane that is lower than the plane defined by the upper edges of the flanges 126 provided to the respective ends of the base portion 106 of the packing system 100, i.e., the upper edges of the flanges are higher than the uprights when the latter are laid flat.

[0063] Referring now to FIG. 7, this shows the top portion 116 of the bracket. As with the base portion and uprights, this may be formed as a molding of a suitably robust plastics material, including, without limitation, original or recycled HDPE and / or PP. Like the uprights, the top portion 116 has an outer face that is formed as a lattice or honeycomb structure, conferring rigidity and strength. The reverse side, not visible in this view, substantially flat and smooth, for a consistent contact surface with the articles or box being transported when the packing system is being used.

[0064] At the respective ends 146 of the outer face of the top portion 116 is provided a slot 148 and a bearing surface 150. As shown in FIG. 8, when the top portion is in use, the slot is in alignment with the vertically orientated slot 142 of the upright 108. The slot 148 of the top portion 116 receives the shaft 114c of the fastening member 114 of the upright 108, while the head 114b of the fastening member may, once the shaft has been sufficiently threaded through the hinging member 114a, contact and bear down the bearing surface 150. The bearing surface may be reinforced with a plate 118 including a metal, such as aluminum, stainless steel, or another suitably durable material. The use of this plate may help distribute the force exerted by the head as it bears down on the top portion, preventing or limiting any damage to the bearing surface through the plastics material used to form the same.

[0065] As seen in FIGS. 7 and 8, the end 146 of the top portion 116 is configured with a pair of protrusions 152. Referring to FIG. 5, in use, these protrusions interlock with complementary recesses provided to the interior surfaces of the flange 126 of the base portion 106. This may help with providing a positive keying-in effect when nesting the respective top portion to the base portion, as will be apparent from the following discussion.

[0066] An alternative embodiment of the upright 108 is shown in FIG. 9. In this embodiment the fastening member 114 is secured in place via the hinging body 114a. In contrast to the previously described embodiment, the hinging body is unable to slide along the recess 140 (the reverse side being shown here) in which it is disposed and is only able to pivot relative to the upright. As a consequence, the slot 138 provided for the fastening member need only substantially approximate the latter's length dimension. To retain the hinging body within the recess, a couple of protrusions (not visible) may be provided about the open face of same (not visible).

[0067] Additionally, in this embodiment, the head 114b of the fastening member 114 may be a separate component in the form of a nut, which is threaded onto the upper end of the fastening member. In this manner the top portion 116 is clamped to the upright 108. This configuration allows for a larger head for the fastening member, potentially allowing for the use of fingers to operate the embodiment rather than an Allen key or the like as may be the case with the embodiment of FIG. 8, for example.

[0068] FIG. 10 shows a variant of the base portion 106 and support rail 104. In this embodiment, the support rail, e.g., an extrusion of aluminum, is configured with flanges 104a that key into corresponding cutouts 120a provided to the recess 120 that receives the support rail in use. This is advantageous in that it better retains the support rail with the base portion in a positive fit, making it more difficult to accidentally separate the respective components. As will be appreciated, this configuration requires the support rail to be slid into the base portion rather than simply being dropped in from above.

[0069] Referring now back to FIGS. 1 to 4, it will be appreciated that the configuration of the bracket 102 of packing system 100 allows for its top portion 116 to be added and removed, and the uprights to be folded up and down, for assembly / disassembly of the bracket as needed. For example, when being used to transport a load of extrusions E, the user determines the number of brackets 102 required to ensure adequate support of the box B that will be used to contain and transport the extrusions (two brackets in the example of FIG. 1). The uprights 108 of each bracket are pivoted into a vertical position relative to the base portion 106. Rails 104 (only visible in FIGS. 1 and 2) are then placed into the appropriate recesses (120 of FIG. 5) for same. Screws or similar fastening members may be passed through the rails and into the base portion to secure the former to the latter.

[0070] In this assembled configuration, but prior to the addition of the top portion 116, the bracket 102 forms a substantially open U-shaped structure into which the box may be placed. Extrusions are loaded into the box until it has reached its capacity. The top portion 116 is then mated with the upper ends of the uprights, and the fastening members 114 articulated to advance the head of same relative to the top portion.

[0071] By this manner, the top portion 116 is effectively clamped against the uprights 108 and the box (not shown) being transported, which in turn is supported by the base portion 106. This provides a means for securing the box for transport. In some instances, a packer material, such as sheets of cardboard or fabrics may be placed across the upper surfaces of the box to help fill in any clearance and optimize the clamping effect.

[0072] Returning to FIG. 7, it will be noted that the top portion 116 has, in plan view, a substantially rectangular profile, similar to that of the base portion (106 in FIG. 5). However, dimensionally, it is a little smaller than the base portion. This means that when the components of the bracket 102 are in a collapsed configuration, as shown in FIG. 11, the top portion 116 fits within the footprint of the base portion 106 in a nested fashion, its underside contacting the outer sides of the uprights 108. The protrusions 152 of the top portion key into the flange 126 of the base portion. As previously noted, the plane defined by the outer sides of the uprights when collapsed is lower than that defined by the respective upper edges of the flanges. This creates a partial recess into which the top portion sits.

[0073] Similarly, the underside of the base portion 106, not visible in FIG. 11, includes a recessed portion that is substantially complementary to the perimeter of the top portion 116. As previously noted, this means that multiple brackets 102 to 102111 may be stacked or otherwise nested upon each other when the uprights 108 and top portion 116 are in the collapsed configuration, as shown in FIG. 12. This may be useful for transport of the brackets back to the point of origin, or for storage when not being used, either prior to return to point of origin or afterwards.

[0074] As shown in FIG. 13, this same nesting functionality is also present when the brackets 102 are assembled and may be used to stack successive boxes B to B111 extrusions. As each successive bracket interlocks or nests with the preceding bracket, this provides some resistance to lateral shifting of the upper boxes, and thus potentially greater stability during transport.

[0075] The brackets 102, and the rails 104, may similarly be nested when not in use, as shown in FIG. 14. This may be storage purposes or for transport back to the place of origin.

[0076] It will be apparent in FIG. 14 that each rail is a separate elongate component and is only linked to the opposing rail through the use of the bracket. As such, it will be understood that the brackets act as cross members, supporting the weight of the box being transported across the width dimension of same.

[0077] However, in some embodiments not illustrated here, rather than the rails 104 being separate components held in fixed relationship to each other by virtue of their engagement with the brackets 102, they may be connected with cross members of hollow rectangular box section profiles. These cross members may be welded or otherwise secured to the respective rails to form a structure similar to a ladder. This may be useful in providing support additional to that provided by the brackets, if required, across the width dimension of the box when it is loaded.

[0078] It should also be noted that a mixture of loaded units (boxes, brackets and rails) and collapsed units (brackets and rails) may also be nested for transport. This may be useful for returning loads to the point of origin; some boxes may be loaded with materials for transport.

[0079] The packing system as herein described is advantageous as it greatly facilitates reuse of its brackets and rails, and as such leads to less wastage of components which may otherwise go to landfill. Furthermore, being primary comprised of plastics material, any damaged components may be recycled.
