Definitions

  • the present invention relates to a pallet racking system and reinforcing assembly therefor.
  • the invention relates to a system that includes intermediate supports consisting of an upright support and a bracket with a base support and upright component which, when assembled, provide support to a pallet racking beam.
  • Pallet storage systems used to store cargo-carrying pallets are known. Such systems typically include a support frame for supporting the pallets and which are loadable from one or more ends of the frame. These frames are generally designed in a grid formation including upright frame assemblies and connected by beams or shelves creating levels upon which the pallets are loaded by a forklift. Typically 2 or more pallets can be accommodated between each frame assembly.
  • a common and known racking system is the 'Drive-in' system wherein the forklift is driven in between the lanes or bays of the system and the pallet is lifted into the racking.
  • the disadvantage of this system is that it is labour intensive given the care the forklift driver must take driving in and out of the racking, and is thus is also time consuming.
  • Another disadvantage is the repair costs which are involved when errors or accidents occur with the forklifts.
  • the 'Pushback' system utilises a forklift to place the pallet into the racking system, whereby the pallets are then pushed back onto inclined rails inside the racking.
  • the 'Flowthrough' system utilizes an incline rail with rollers and braking systems which move the pallets along a slope and wherein the pallets are loaded from one end (either the back or front of the system) and unloaded from the other end.
  • the horizontal cross beams in each system must be sturdy and made from a sufficiently durable material so as to adequately support the weight of several pallets.
  • the beams are commonly therefore made from steel or other similarly sturdy material, however use of heavy duty steel beams in pallet racking is cost prohibitive.
  • Cross beams made from cheaper and lighter material or beams of a lower cross- sectional amount of steel can be used and are desirable, however, the lack of strength in these beams can lead the centre of the beam to depress, distort or rotate under the pressure of the pallet weight and movement.
  • the beam is therefore structurally weak and dangerous and cannot accommodate the desired weight of the pallets.
  • the object of this invention is to provide racking system including additional uprights with support brackets which alleviate some of the abovementioned problems, or at least provides the public with a useful alternative.
  • a further object of the invention is to provide a reinforcing assembly for use in such racking systems.
  • any one of the aspects mentioned above may include any of the features of any of the other aspects mentioned above and may include any of the features of any of the embodiments described below as appropriate.

  • said cross beam is of a length sufficient to accommodate two side by side and spaced apart pallets.
  • said additional upright support and associated bracket is disposed approximately halfway between said upright frame assemblies to thereby assist in supporting a cross beam with two pallets on opposed sides of said bracket.
  • said bracket includes a main body configured to be secured to the additional upright support.
  • said bracket further includes a base support surface extending outwardly from said main body to thereby support said cross beam.
  • said additional upright support is disposed rearwards of said cross beam, and the base support surface extends forwardly from said main body.
  • said base support surface is horizontal.
  • said base support surface includes a curvature along its length adapted to correspond with a curvature along said cross beam when pallets are supported on either side of said bracket.
  • said base support surface further includes rounded off edges.
  • bracket further includes an upright support surface for preventing said cross beam from movement along said depth dimension relative to said additional upright support.
  • said system includes a plurality of vertically spaced cross beams extending between each pair of spaced apart upright frame assemblies disposed along the depth dimension of the racking system.
  • cross beams are substantially aligned along said depth dimension such that racked pallets are supported and moveable along the aligned cross beams.
  • the cross beams that are substantially aligned along said depth dimension form a slight angle for facilitating movement of the racked pallets by gravity along said depth dimension.
  • a reinforcing assembly for a frame system having a frame assembly with a width and a depth dimension, said width dimension being defined by two outer upright frame assemblies, said reinforcing assembly further including one or more cross beams extending horizontally between said two outer upright frame assemblies, wherein substantially aligned cross beams along the depth dimension of the racking system are adapted to support a load, said upright support assembly including:
  • At least one additional upright frame member adapted to be disposed on a front or rear side of said cross beam between the two outer frame assemblies, said additional upright frame member having at least one bracket configured to assist in supporting said cross beam and load.
  • the skilled addressee would thus realize how the reinforcing assembly comprising the additional upright support and bracket effectively halve the span of a cross beam without requiring the addition of a new upright frame assembly and/or requiring the beam to be shortened.
  • the present invention could thus have application in a number of different structural systems and not necessarily only in pallet racking systems.
  • said frame system is a pallet racking system and said load is in the form of one or more pallets.
  • cross beam is of a length sufficient to accommodate two side by side and spaced apart pallets.
  • said additional upright support and associated bracket is disposed approximately halfway between said upright frame assemblies to thereby assist in supporting a cross beam with two pallets on opposed sides of said bracket.

  • the present invention relates to a pallet racking system and bracket therefor which allows for horizontal cross beams supporting the pallets to be constructed of cheaper and lighter material and/or be of lesser cross sectional size than hitherto known beams used in conventional pallet racking systems.
  • the present invention can be used in conjunction with either the "Pushback” or “Flowthrough” racking systems which are known, but it is to be understood that the invention could equally well be applied to any kind of racking system.
  • a racking system 20 according to the known type consisting of two outer (or side) upright frame assemblies 26 and a centre upright frame assembly 28, between which extend horizontal cross beams 24 onto which pallets (not shown) can be loaded.
  • the system 20 includes a plurality of such frames spaced along its depth.
  • the front facade of the system 20 includes three upright frame assemblies 26 and 28, with five vertically spaced cross beams 24 extending between each side and central frame assembly, however the invention can be applied to alternately configured systems having two or even four or more upright frame assemblies and any number of vertically spaced cross beams.
  • the beams therefore, extend between the outer frame assemblies 26 and the centre frame assembly 28, attached by known methods such as a bracket.
  • the spacing between the outer assembly 26 and the centre assembly 28 allows for the insertion of two pallets resting comfortably next to one another (with a gap there between), and further beams 24 are attached in the same way extending the depth of the racking system.
  • the cross beams in adjacent rows are aligned (typically on an angle as mentioned in the preamble) and thus provide a secure shelf upon which the pallets can be loaded.
  • cross beams usually made from steel, need to be of a certain dimension and strength in order to support the pallets properly, however such volumes of steel are costly. It would be advantageous for the beams to be either made of a lighter material or from less steel, but still allow pallets of the same weight to be loaded into the racking system.
  • Lighter beams can be used, however this requires additional upright frame assemblies, usually the same as those which are used for the outer and centre assemblies, to be inserted between each of the pallets in order to provide the required support.
  • additional frame assemblies are more cost effective than the heavier beams, but can still be cost prohibitive.
  • the use of shorter beams and additional frame assemblies equates to more cost for end brackets required at each end of the cross beams.
  • the present invention proposes the use of additional upright supports 30, rather than additional frame assemblies.
  • These upright supports 30 are similar to the frame assemblies 26 and 28 in that they comprise one or more upright posts having spaced apart engagement apertures (not numbered for the purpose of brevity) along their height and/or width, however, because the additional support is disposed behind the cross beam and not in line with it, one beam can still be used to support two pallets between two. upright assemblies. If a standard upright assembly were used instead, two beams would be required as well as two end brackets.
  • the additional supports will not require the diagonal or horizontal braces 29 which the frame assemblies use to connect and support the assemblies along the depth of the racking system..
  • the additional supports are effectively freestanding, much less material is required, and use of the upright supports 30 is far more cost effective than use of additional frame assemblies.
  • the additional supports can be made from known and existing materials.
  • the upright support 30 is disposed halfway between each outer upright frame assembly 26 and the centre upright frame assembly 28 and thereby creates two channels on either side thereof for the insertion of two pallets.
  • four pallets could be stored across the width of the racking system, that is, on two cross members which together span the width between the outer upright frame assemblies.
  • the upright supports extend vertically the height of the frame, as seen in Figure 1 and are preferably attached at the rear of each of the horizontal beams 24 through use of a bracket 32 (not shown in Figure 1 ).
  • the rear positioning of the upright support 30 takes advantage of the stronger front side of the uprights and supports the rear of the cross beam. It can thus be appreciated that each additional support is effectively a vertical structure positioned at a point along a horizontal cross beam and connected thereto using a bracket 32, to provide additional support for the cross beam when one or more pallets is placed on the cross member. In using cross beams of reduced material and strength, such support is necessary and would otherwise not be provided by the upright frame assemblies alone.
  • the upright supports 30 are preferably attached to the beams 24 at the halfway point between the outer upright frame 26 and the centre upright frame 28. As the racking system 20 is designed to accommodate two pallets in this space, the upright support 30 therefore does not interfere with the loading of the pallets, and once loaded, there is a pallet on either side of the upright support 30.
  • the upright supports therefore reinforce the beams 24 which use much less steel than regular beams and allow pallets of the same weight to be loaded onto the racking system 20 without compromising the integrity of the beams.
  • the upright supports 30 are therefore far more cost effective than use of additional frame assemblies in a "Pushback" and "Flowthrough” system.
  • the upright supports 30 also allow the use of reduced capacity beams, typically a beam with a steel thickness of 9mm as opposed to the standard 12mm, yet still hold the same pallet weight:
  • Bracket 32 which provides the support for the cross beam 24 and attaches to the upright supports 30.
  • the bracket 32 includes a main perpendicular body portion 33 having two angled apertures 34 through a front face thereof, the apertures being spaced a short distance from the vertical ends of the front face. Extending downwardly from these apertures on the reverse side of the front face are lugs (not shown) which are adapted to engage with corresponding apertures on the additional upright support 30. The bracket is therefore locked into place against the upright support 30.
  • the upright support apertures also mentioned earlier in this description, are not described in detail as such apertures and their means of engagement with corresponding lugs (not shown) is well known in the art.
  • brackets 32 can be used for the upright frame assemblies 26 and 28 and upright supports 30. While it is a preferred embodiment of the invention that the bracket 32 be the same as that which is used to secure the upright frame assemblies 26 and 28, it is to be understood that the bracket can be manufactured separately if desired.
  • the bracket 32 further includes two L-shaped platforms 36 and 38 which when assembled, as described below, provide a means of supporting a cross beam.
  • the lower L-shaped platform 36 is preferably welded to the front face of the main body 33, and preferably some 1 15mm from the top of the front face as seen in Figure 2.
  • the length of the platform 36 is greater than that of the bracket 32 and thus the platform 36 extends outwardly from the bracket, preferably by some 47mm.
  • the lower L-shaped platform 36 also contains two circular apertures 40, preferably some 21mm from either end of the platform.
  • the upper L-shaped platform 38 also includes two apertures 42 in a corresponding and co-aligned position.
  • bracket 32 including two platforms.
  • the platforms need not be L- shaped and could indeed be replaced with a single member for supporting the cross beam.
  • the upper L-shaped platform 38 is adapted to engage the lower platform as shown most clearly in the exploded view of Figure 2, that is, such that the base of the upper platform 38 rests against the lid of the lower platform 36 creating a U-shaped pocket 44 as seen in Figure 3.
  • This allows the apertures 40 and 42 of both platforms to align and bolts 46 can be inserted therein to secure platform 38 to platform 36.
  • the bolts 46 are counter-sunk and do not extend above the apertures 40 and 42.
  • the U-shaped pocket 44 created by the bracket 32 and platform 38 is therefore adapted for the insertion of the beam 24, with the underside of the beam 24 resting upon the base of the platform 38.
  • the beam is then held and secured in the pocket 44 and as the pocket 44 is of a relative size to the beam 24, it does not move within the pocket 44.
  • the lower platform 36 therefore provides the strength and support to ensure that the beam 24 does not depress and.
  • the upper platform 38 holds the beam 24 in place so that it does not stretch outwardly or distort.
  • the pocket 44 also holds the beam securely so that there is no rotation of the beam 24 when the pallets are pushed over it as is customary in the 'Pushback' and 'Flowthrough' racking systems.
  • the upper L-shaped platform is not fixed to the bracket 32, it can be altered depending on the type of beam 24 used. If the beam 24 is of a greater height, the upper platform 38 and lower platform 36 can be attached as described above. If the beam 24 is of a lower height, a spacer (not shown) can be placed between the upper and lower platforms and bolted to the upper platform 38. This provides the additional height required to ensure that the upper platform 38 reaches the desired height to support the beam 24.
  • the same bracket 32 and platforms 36 and 38 can be manufactured and altered as desired by the end user, rather than separate bracket and platform combinations requiring construction.
  • FIG 4 there is illustrated the desired arrangement of an additional support provided to a pallet racking system in accordance with the present invention.
  • the cross beam 24 of reduced strength/size sits inside pocket 44 and is supported above the platforms 36 and 38 of bracket 32, which is securely attached to the upright support 30 via its main body portion 33. It has been found that the bracket 32 and additional support . 30 provides the necessary reinforcement to each cross beam 24 to support the weight of two pallets stacked thereabove and on either side of the bracket.
  • the skilled addressee would thus realize from a reading of the first embodiment of the present invention how the system 20 and reinforcing assembly comprising the additional upright support 30 and bracket 32 effectively halve the span of a cross beam without requiring the addition of a new upright frame assembly and/or requiring the beam to be shortened.

  • bracket 52 when a load (a pallet) is placed on either side of the bracket, the beam will adopt a slight curvature owing to its reduced strength characteristics. Accordingly, the shape of the base support surface 56 of bracket 52 is designed Correspondingly with the envisaged curvature of the cross beam to increase the abutting surface area and thus reduce stress concentration at any one point.
  • the bracket 52 further includes an upright portion 59 for preventing movement of the beam 24 along a depth dimension of the frame relative to the support 30, two reinforcing braces 60 beneath the base support surface adapted to contact the main body 53, as well as apertures 60 in the event it is necessary to lock the cross beam to the bracket 52 using known fastening means.

Abstract

La présente invention concerne un ensemble de renfort de montant à utiliser avec un système de palettier et un système de rayonnage comprenant ledit ensemble. Le dispositif de support est constitué d'un support de montant auquel est attachée une équerre de support comportant deux plateformes en L qui forment un berceau. Le dispositif de support de montant est placé entre deux ensembles de structure pour soutenir la lisse, qui est maintenue dans le berceau créé par l'équerre, apportant ainsi un support supplémentaire pour la lisse et empêchant une rotation, un fléchissement ou une déformation de la lisse. Un tel dispositif abaisse le coût d'un palettier puisque des lisses de moindre capacité peuvent être employées ou un nombre réduit d'ensembles de structure sont nécessaires dans le rayonnage.
