Definitions
- the present invention relates to a runner assembly of the type adapted to support a shelving unit thereabove, and which is slideable along a track providing the shelving unit with mobility.
- US 6681702 discloses a wheeled skate which includes an inverted U-shaped elongated channel member, two housings, and two wheels.
- the channel member has apertures formed in the top near both ends of the member.
- Each housing is in an inverted U-shape and has a rounded portion covering one end.
- Apertures are formed in the top and sides of each housing.
- Each wheel has a bushing and axle that pass through the centre thereof. The wheel is inserted into its respective housing so that the axle fits into the apertures formed within the sides of the housing.
- Each housing is then secured within an end of the channel member.
- a bult is inserted through each aperture formed within the top of the channel member and is secured to the bottom of the storage device.
- the wheel is secured directly to the elongated channel member via a bolt.
- Mobile shelving systems typically comprise a plurality of mobile shelving units which are moveable along spaced apart tracks, with each individual shelf unit being a tall and narrow structure having an array of horizontal shelves.
- the shelving units are attachable to structures known as runners which are con figured to slideably traverse the track.
- runners are in the form of elongate brackets to which different items such as cross members joining two runners together, the shelving units, rollers, etc, are attachable.
- a problem with existing runner assemblies is that significant post-processing of the runner bracket is required after it has been cut to size. For example, a plurality of apertures need to be drilled into the runner bracket, as well as slots and other mounting means, in order to accommodate the various shelving system components such as cross members, motors, etc. This not only increases the complexity of the apparatus, and the amount of parts, but also increases general costs in relation to manufacture, and labour that is required to assemble and install the shelving units on site.
- a runner assembly for slidably supporting a mobile shelving unit above a longitude track, said runner characterised by:
- the runner incorporate an array of slots allowing for fastening of a roller cartridge, different types of shelving, and cross member bracket, as well as other items at any desired position along the runner.
- said end bracket further includes a means of engaging said longitudinal track to prevent tilt of the mobile shelving unit.
- said means of engaging said longitudinal track is in the form of two transversely extending shoulders which extend from the base of said end bracket.
- a track and runner assembly 10 for mobile shelving is shown in Figures 1-4 .
- the assembly 10 comprises one or more longitudinal tracks 12, a longitudinal runner 14 configured to slideably engage each track 12 and to support a shelving unit (not shown), otherwise known as a compactus, thereabove, and transverse cross members 16 for connecting two or more runners 14 together.
- a typical shelving unit is adapted to be mounted above two runners 14 slideable along two tracks 12 which are spaced apart by a distance corresponding approximately with the length of the shelving unit.
- the runner 14 of the present invention is shown most clearly in Figures 5-6 .
- the runner 14 is substantially in the form of an inverted U-shaped extrusion, having a primary channel 18 extending there along adapted to accommodate one or more roller cartridges 20, and four slots 22, 24, 26 and 28 extending along right, left and top sides thereof.
- slot 22 extends along the left side of the runner 14
- slot 24 extends along the right side
- slots 26 and 28 extend along the upper side of the runner 14.
- the slots 22, 24, 26 and 28 are preferably in the form of T-slots, shaped like so to accommodate square nuts 30 having internal threads. This provides for fast, versatile construction because the nut 30 provides an anchor point for external items at any point along the runner 14.
- the item which typically includes a mounting aperture 32, is moved into position so that the aperture 32 and nut 30 become coaxially aligned.
- a screw 34 is used to extend through the aperture 32, through the slot 22, 24, 26 or 28, and into the nut 30 for threaded engagement therewith.
- Extending centrally along the top of the primary channel 18 is a further slot 36 providing a further mounting means for the roller cartridges 20 and end brackets 38, as will become apparent.
- the runner 14 has been designed so that no additional post-processing of the extrusion is required after it has been cut, i.e. no drilling, slotting, etc.
- Clip 42 configured for engagement with a corresponding receiving means located beneath the shelving unit, such as a correspondingly shaped aperture (not shown), for example.
- Clip 42 includes a mounting portion 44 having a mounting aperture 46 extending there through, and a second portion 48 upstanding from the mounting portion 44 and doubled over for engagement with the corresponding receiving means.
- the clips 42 are fixed to the runner 14 using a screw 34 adapted to extend through aperture 32 to thereby engage a nut 30 located within slot 28, as described above. In the embodiment shown, there are two spaced apart clips 42 for each runner 14.
- Two cross members 16 are adapted to extend between runners 14 on spaced apart tracks 12 to provide the required support for each shelving unit.
- the cross members 16 are in the form of substantially I-shaped extrusions having slots 50, 52 and 54 on left side, right side and top sides thereof, respectively.
- the slots 50, 52 and 54 are also substantially in the form of T-slots engageable by screw/nut connections as described above, when mounting external items thereto.
- Each cross member 16 is coupled to the runner 14 using hollow, triangular shaped brackets 56 at the junction therebetween.
- the perpendicular walls of the bracket 56 include outwardly extending projections 58 being shaped to fit snugly within the side slots 52 and 22 of both the cross member 16 and the runner 14 respectively.
- the projections 58 are ribbed to facilitate insertion through the slots and so that any impact loads on the bracket 56 are reduced.
- mounting apertures 32 are also located on the perpendicular walls of the bracket 56.
- the mounting apertures 32 on the bracket 56 are positioned to fix the cross member 16 in a perpendicular arrangement relative to the runner 14, that is, each perpendicular wall of the bracket 56 is mounted to the cross member 16 and runner 14 respectively.
- nuts 30 and screws 34 are preferably used for connecting the respective components.
- the runner 14 In order for the runner 14 and hence the shelving unit to be slideable along the track 12, the runner 14 must also include means of housing the roller cartridges 20 mentioned above.
- the present invention provides that the primary channel 18 of the runner 14 accommodates one or more roller cartridges 20.
- Each roller cartridge 20 is also of an inverted U-shaped configuration and of a size to fit inside the runner primary channel 18.
- the top side of the cartridge 20 includes two spaced apart mounting apertures 32, so that when the cartridge 20 is positioned in a desired location along the channel 18, it can be secured using self-tapping screws 34 extending through the apertures 32 and into slot 36.
- Such a configuration means that the rollers may be fitted to the runner 14 without the need for drilling.
- each shelving unit will include a roller at longitudinal ends of each runner 14, however, there may be circumstances where more are required, and the runner channel 18 may accommodate for this.
- the roller cartridge 20 includes larger, co-axially aligned apertures 60 extending through its side walls.
- a pin 62 which extends through the apertures is used to maintain a roller 69 inside the cartridge 20.
- the roller 69 is rotatable about the pin 62 and allows the runner 14 and hence the shelving unit to move relative to the track 12, as will become apparent.
- end brackets 38 are mounted to the runner 14 as mentioned. Not only are the end brackets 38 used to cap off the ends of the runner 14, they are configured to prevent the shelving unit from tilting.
- Each end bracket 38 is in the form of a rigid housing having an internal structure which corresponds substantially in shape with the cross section of the runner extrusion, so that it may engage an end thereof
- a self-tapping screw 34 is used to fix the end bracket 38 in place, the screw 34 extending through an uppermost aperture 32 of the bracket 38, and into the runner slot 36.
- At the base of the end bracket 38 are two transversely extending shoulders 64 which when engaged with the track (as described below), are designed to prevent the shelving unit from toppling over.
- the end bracket 38 therefore constitutes the anti-tilt means of the assembly 10.
- the track 12 is also made up of an extruded length of metal and includes a hollow profile.
- the track 12 comprises generally a base 66, internal walls 68, 70, 72 and 74, and external walls 76 and 78 which are each integrally formed.
- the external walls 76 and 78 at upper ends of the track 12 extend a short distance inwardly, past internal walls 70 and 72.
- the base 66 and the external walls 76 and 78 form a substantially triangular cross-sectional shape, however, because the external walls fall short of meeting at an apex, they define a central channel 80 extending along the track 12.
- the internal geometry of the track 12, in particular the high, hollow profile, allows for robust but unobtrusive track joining, and should remove the need for installers to use glue and fit fasteners with high precision, as will become apparent.
- the inside surface of internal walls 70 and 72 are shaped to perform two functions. Firstly, at a lowermost region of the channel 80, the internal walls 70 and 72 define a V-shaped guide 82, which is the surface upon which the rollers 69 are supported. The rollers 69 engage the guide 82 centrally with both edges of the roller 69 contacting the guide. The weight of the shelving unit on the roller retains it in the desired position, and allows sufficient friction for it to rotate smoothly across the guide. In order to prevent wear, and to strengthen the guide, retaining beads (not shown) retain crinoline strips, generally made of steel, along the V-shaped guide 82.
- hollow regions 86 are defined between internal walls 68 and 70, and internal walls 72 and 74.
- the hollow regions 86 are adapted to accommodate joining pins 88 which are used to join two track ends together.
- the hollow regions 86 also accommodates pins 90 associated with an end stop bracket 92 of the track 12. Therefore, the end stop bracket 92 is mounted to the end of the track 12 using two joining pins 90 associated therewith, while for joining two segments of track 12 together, individual joining pins 88 are used, as shown in Figure 1 .
- the joining pins 88 and 90 include a plurality of apertures 94 spaced apart there along, and are adapted to be inserted into the hollow regions 86 of the track 12 until they are in co-axial alignment with apertures 96 extending through the base 66 of the track 12. Self-tapping screws 34 are once again used to engage the coaxial apertures and thereby secure the components together.
- the end stop bracket 92 is adapted to be mounted to the end of a track 12.
- An enlarged view of the end stop bracket 92 is shown in Figure 9 and it can be seen that it comprises a substantially triangular shaped housing 98, joining pins 90 extending outwardly from an internal bracket plate 100, and a stop portion 102 extending between the pins 90 and into channel 80 when the bracket 92 is mounted to the track 12.
- the stop portion 102 includes a plurality of ribs 104 which provide an elastomeric buffer for reducing impact loads. Shelving units when moved generate a significant amount of force due to their weight and therefore require that the track end stops be robust enough to dampen such force upon impact.
- the end stop bracket 92 also includes anti-tilt shoulders 106 as per the runner end brackets 38.
- the height of the track 12 also needs to be maintained level along its length. It is also preferable for the height of the track 12 to also be easily adjustable even after assembly.
- Each packer 108 is substantially rectangular in shape and includes a 3x2 matrix of apertures 110 extending there through.
- One row of three apertures 110 of the packer 108 includes elevated square surrounding portions 112.
- the adjacent row of three apertures 110 include locating means 111 for engaging the elevated square surrounding portions 112 of a second packer 108 positioned therebeneath.
- Each adjacently stacked packer 108 is rotated by 180 degrees relative to the other.
- One or more packers 108 are adapted to sit beneath the joining pins 90 at the ends of the track 12, as well as beneath the joining pins 88 at one or more joints between track segments.
- the apertures 110 are designed to accommodate the head portions of the self-tapping screws 34 which engage the joining pins 88 and 90. Those skilled in the art would realise that any number of stacked packers 108 could be added or removed to increase or decrease the height of a particular section of track 12.
- a further advantage to the improved stiffness characteristics of the track extrusion is that it allows for wider spacing of the packers 108 along the track 12.
- the assembly 10 includes a plurality of optionally attachable ramp sections 114. These are used to provide a smooth surface over the track 12 and prevent the track 12 from forming a tripping hazard.
- Each ramp section 114 includes a substantially rectangular body 116 having a hook section 118 at one end thereof, and a straight edge 120 at the opposed end adapted to lie substantially flush with the ground when assembled.
- the ramp section body 116 includes a plurality of ribs 122 on its upper surface for gripping purposes. There are reinforcing members 124 positioned below the body 116 which are advantageous because they reduce the overall weight of the ramp section and maintain strength.
- the hook section 118 extends downwardly from the body 116, then inwardly and upwardly with respect to the track 12.
- the track extrusion is also designed to accommodate the ramp sections 114.
- FIGs 10-11 between the lower end of the external walls 76 and 78, and the internal walls 68 and 74 respectively, there are defined receiving channels 125 for engaging the hook section 118 of each ramp section 114.
- each ramp section 114 is configured to engage the receiving channels 125 by way of a rotatable snap-fit.
- Figure 12 illustrates this process, whereby the hook section 118 is inserted into the receiving channel 125 and then urged upwardly while rotating edge 120 of the body downwardly until the hook section 118 is snap-fit in place.
- This ramp pivot geometry is designed to allow removal and refitting of ramps (for re-levelling purposes) without having to lift up or up-end the track 12.
- a rubber tube 126 is also inserted between the rounded end of the external walls 76 and 78 and the junction between the downwardly and inwardly extending surfaces of the hook section 118.
- the tube 126 provides a down-force and minimises ramp "kick-up" which could create a tripping hazard.
- a further advantage to the rubber tube 126 is that it also acts as a flexible joiner, assisting in handling and simultaneous fitting of multiple ramp sections to the track 12.
- the ramps are optional as the track extrusion has been designed to be aesthetic and safe even if used without ramps 114.
- a locking bracket 40 is shown in the drawings which is also engageable to an upper slot 28 of the runner 14, as well as the side slots, by means described above.
- the locking bracket 40 includes a housing 128 mounted to the runner 14, the housing 128 defining a vertical chamber extending downwardly alongside the runner 14 to the track 12.
- the chamber includes a vertical aperture 130.
- a jig 136 is provided for forming the pre-drilled apertures 132 in the track 12.
- the jig 136 is an elongate structure mountable to the track 12 in a transverse arrangement as shown in Figure 1 .
- the jig 136 includes a downwardly extending section 138 at its centre which extends inside channel 80, as well as downwardly extending sections 140 at ends thereof which abut with the external walls 76 and 78 of the track 12.
- On opposed ends of the jig 136 are apertures 144 and 146.
- the jig 136 is first adapted to be mounted to the track 12 so that aperture 144 is positioned over a desired point to be drilled.
- the purpose of this smaller aperture 144 is to mark the track 12 with a suitable tool (not shown), the mark acting as a locating guide for a drill bit or the like used to drill a hole through the track 12.
- the jig 136 is then demounted from the track 12, rotated by 180 degrees, and mounted to the track 12 again so that the larger aperture 146 extends over the marked point.
- a drill (not shown) can then be used to drill a hole through the track 12 where marked.
- one of the track external walls 78 would extend a greater distance outwards from the channel 80 and include a flat upper surface (not shown) for accommodating a drive wheel (not shown).
- Such a track would therefore include a further hollow region 86.
- the same packers 108 could be used but simply rotated by 90 degrees so that instead of extending longitudinally relative to the track 12, it would extend transversely.

Description
- The present invention relates to a runner assembly of the type adapted to support a shelving unit thereabove, and which is slideable along a track providing the shelving unit with mobility.
-
US 6681702 discloses a wheeled skate which includes an inverted U-shaped elongated channel member, two housings, and two wheels. The channel member has apertures formed in the top near both ends of the member. Each housing is in an inverted U-shape and has a rounded portion covering one end. Apertures are formed in the top and sides of each housing. Each wheel has a bushing and axle that pass through the centre thereof. The wheel is inserted into its respective housing so that the axle fits into the apertures formed within the sides of the housing. Each housing is then secured within an end of the channel member. A bult is inserted through each aperture formed within the top of the channel member and is secured to the bottom of the storage device. In a second embodiment, the wheel is secured directly to the elongated channel member via a bolt. - Mobile shelving systems typically comprise a plurality of mobile shelving units which are moveable along spaced apart tracks, with each individual shelf unit being a tall and narrow structure having an array of horizontal shelves. In particular, the shelving units are attachable to structures known as runners which are con figured to slideably traverse the track.
- Typically runners are in the form of elongate brackets to which different items such as cross members joining two runners together, the shelving units, rollers, etc, are attachable. A problem with existing runner assemblies is that significant post-processing of the runner bracket is required after it has been cut to size. For example, a plurality of apertures need to be drilled into the runner bracket, as well as slots and other mounting means, in order to accommodate the various shelving system components such as cross members, motors, etc. This not only increases the complexity of the apparatus, and the amount of parts, but also increases general costs in relation to manufacture, and labour that is required to assemble and install the shelving units on site.
- Furthermore, even with significant post-processing, existing runner brackets are not configured to be truly versatile in terms of where along the runner the items are mountable. There is therefore a need in the industry for a universal mobile platform to which different types of shelving, and other items, can be attached providing for rapid, versatile construction.
- It is an object of the present invention to overcome at least some of the aforementioned problems or to provide the public with a useful alternative.
- Therefore in one form of the invention there is proposed A runner assembly for slidably supporting a mobile shelving unit above a longitude track, said runner characterised by:
- a longitudinal body including at least one outer vertical planar portion;
- at least one slot extending longitudinally alongan outer side of said at least one outer vertical planar portion, said at least one slot having one or more fastening means therein at desired positions along its length or to an end of the runner, whereby the or each of said fastening means is used to attach a mobile shelving component to the longitudinal body, and
- Therefore, no additional post-processing of the runner is required after it has been cut to size, for example, no additional drilling or slotting. The runner incorporate an array of slots allowing for fastening of a roller cartridge, different types of shelving, and cross member bracket, as well as other items at any desired position along the runner.
- In preference said end bracket further includes a means of engaging said longitudinal track to prevent tilt of the mobile shelving unit.
- Preferably said means of engaging said longitudinal track is in the form of two transversely extending shoulders which extend from the base of said end bracket.
- The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate several implementations of the invention and, together with the description, serve to explain the advantages and principles of the invention. In the drawings:

Although the description includes exemplary embodiments, other embodiments are possible, and changes may be made to the embodiments described without departing from the scope of the invention. Wherever possible, the same reference numbers will be used throughout the drawings and the following description to refer to the same and like parts.
- Whilst the present invention is directed specifically towards a runner assembly for mobile shelving, other components which form part of a complete mobile shelving system according to a preferred embodiment of the invention are also described.
- A track and
runner assembly 10 for mobile shelving is shown inFigures 1-4 . Theassembly 10 comprises one or morelongitudinal tracks 12, alongitudinal runner 14 configured to slideably engage eachtrack 12 and to support a shelving unit (not shown), otherwise known as a compactus, thereabove, andtransverse cross members 16 for connecting two ormore runners 14 together. A typical shelving unit is adapted to be mounted above tworunners 14 slideable along twotracks 12 which are spaced apart by a distance corresponding approximately with the length of the shelving unit. - The
runner 14 of the present invention is shown most clearly inFigures 5-6 . Therunner 14 is substantially in the form of an inverted U-shaped extrusion, having aprimary channel 18 extending there along adapted to accommodate one ormore roller cartridges 20, and fourslots slot 22 extends along the left side of therunner 14,slot 24 extends along the right side, andslots runner 14. Theslots square nuts 30 having internal threads. This provides for fast, versatile construction because thenut 30 provides an anchor point for external items at any point along therunner 14. - Once the
nut 30 is moved to a desired position, the item, which typically includes a mountingaperture 32, is moved into position so that theaperture 32 andnut 30 become coaxially aligned. Ascrew 34 is used to extend through theaperture 32, through theslot nut 30 for threaded engagement therewith. Extending centrally along the top of theprimary channel 18 is afurther slot 36 providing a further mounting means for theroller cartridges 20 and endbrackets 38, as will become apparent. - The
runner 14 has been designed so that no additional post-processing of the extrusion is required after it has been cut, i.e. no drilling, slotting, etc. - The description in the following paragraphs relate to examples of items which are mountable to the
runner 14. Some of these are necessary items, for example, thetransverse cross members 16, but others are not necessarily essential, such as a lockingbracket 40 for example. It is to be understood that other items which are not shown and described herein, could also be mounted to therunner 14, for example, sensors (not shown), motors (not shown), mechanical drive devices, and the like. - Mounted above the
runner 14 are one ormore clips 42 configured for engagement with a corresponding receiving means located beneath the shelving unit, such as a correspondingly shaped aperture (not shown), for example.Clip 42 includes a mountingportion 44 having a mountingaperture 46 extending there through, and asecond portion 48 upstanding from the mountingportion 44 and doubled over for engagement with the corresponding receiving means. Theclips 42 are fixed to therunner 14 using ascrew 34 adapted to extend throughaperture 32 to thereby engage anut 30 located withinslot 28, as described above. In the embodiment shown, there are two spaced apart clips 42 for eachrunner 14. - Two
cross members 16 are adapted to extend betweenrunners 14 on spaced apart tracks 12 to provide the required support for each shelving unit. Thecross members 16 are in the form of substantially I-shapedextrusions having slots slots - Each
cross member 16 is coupled to therunner 14 using hollow, triangular shapedbrackets 56 at the junction therebetween. The perpendicular walls of thebracket 56 include outwardly extendingprojections 58 being shaped to fit snugly within theside slots cross member 16 and therunner 14 respectively. Theprojections 58 are ribbed to facilitate insertion through the slots and so that any impact loads on thebracket 56 are reduced. - Also located on the perpendicular walls of the
bracket 56 are mountingapertures 32. The mountingapertures 32 on thebracket 56 are positioned to fix thecross member 16 in a perpendicular arrangement relative to therunner 14, that is, each perpendicular wall of thebracket 56 is mounted to thecross member 16 andrunner 14 respectively. Again, nuts 30 and screws 34 are preferably used for connecting the respective components. - In order for the
runner 14 and hence the shelving unit to be slideable along thetrack 12, therunner 14 must also include means of housing theroller cartridges 20 mentioned above. The present invention provides that theprimary channel 18 of therunner 14 accommodates one ormore roller cartridges 20. - Each
roller cartridge 20 is also of an inverted U-shaped configuration and of a size to fit inside the runnerprimary channel 18. The top side of thecartridge 20 includes two spaced apart mountingapertures 32, so that when thecartridge 20 is positioned in a desired location along thechannel 18, it can be secured using self-tappingscrews 34 extending through theapertures 32 and intoslot 36. Such a configuration means that the rollers may be fitted to therunner 14 without the need for drilling. Typically, each shelving unit will include a roller at longitudinal ends of eachrunner 14, however, there may be circumstances where more are required, and therunner channel 18 may accommodate for this. - The
roller cartridge 20 includes larger, co-axiallyaligned apertures 60 extending through its side walls. Apin 62 which extends through the apertures is used to maintain aroller 69 inside thecartridge 20. Theroller 69 is rotatable about thepin 62 and allows therunner 14 and hence the shelving unit to move relative to thetrack 12, as will become apparent. - Also mounted to the
runner 14 areend brackets 38 as mentioned. Not only are theend brackets 38 used to cap off the ends of therunner 14, they are configured to prevent the shelving unit from tilting. Eachend bracket 38 is in the form of a rigid housing having an internal structure which corresponds substantially in shape with the cross section of the runner extrusion, so that it may engage an end thereof A self-tappingscrew 34 is used to fix theend bracket 38 in place, thescrew 34 extending through anuppermost aperture 32 of thebracket 38, and into therunner slot 36. At the base of theend bracket 38 are two transversely extendingshoulders 64 which when engaged with the track (as described below), are designed to prevent the shelving unit from toppling over. Theend bracket 38 therefore constitutes the anti-tilt means of theassembly 10. - Referring now to
Figures 7-8 in particular, it can be seen that thetrack 12 is also made up of an extruded length of metal and includes a hollow profile. Thetrack 12 comprises generally abase 66,internal walls external walls external walls track 12 extend a short distance inwardly, pastinternal walls base 66 and theexternal walls central channel 80 extending along thetrack 12. - The internal geometry of the
track 12, in particular the high, hollow profile, allows for robust but unobtrusive track joining, and should remove the need for installers to use glue and fit fasteners with high precision, as will become apparent. - The inside surface of
internal walls channel 80, theinternal walls guide 82, which is the surface upon which therollers 69 are supported. Therollers 69 engage theguide 82 centrally with both edges of theroller 69 contacting the guide. The weight of the shelving unit on the roller retains it in the desired position, and allows sufficient friction for it to rotate smoothly across the guide. In order to prevent wear, and to strengthen the guide, retaining beads (not shown) retain crinoline strips, generally made of steel, along the V-shapedguide 82. - Secondly, disposed above the V-shaped
guide 82 are opposedrecesses 84 for accommodatingshoulders 64 associated with theend bracket 38. Those skilled in the art would realise that when the assembledrunner 14 is positioned above thetrack 12, with the shelving unit supported thereabove, any lateral movement of the shelving unit would be restricted by theshoulders 64, because they are prevented from upward movement by the upper ends of theexternal walls - Between
internal walls internal walls hollow regions 86 are defined. Thehollow regions 86 are adapted to accommodate joiningpins 88 which are used to join two track ends together. Thehollow regions 86 also accommodatespins 90 associated with anend stop bracket 92 of thetrack 12. Therefore, theend stop bracket 92 is mounted to the end of thetrack 12 using two joiningpins 90 associated therewith, while for joining two segments oftrack 12 together, individual joiningpins 88 are used, as shown inFigure 1 . - In both cases, the joining
pins apertures 94 spaced apart there along, and are adapted to be inserted into thehollow regions 86 of thetrack 12 until they are in co-axial alignment withapertures 96 extending through thebase 66 of thetrack 12. Self-tappingscrews 34 are once again used to engage the coaxial apertures and thereby secure the components together. - The
end stop bracket 92, as its name suggests, is adapted to be mounted to the end of atrack 12. For example, there could be three or four track segments joined to form a single track, wherein the two endmost track segments include end stopbrackets 92 for preventing therunner 14 from travelling beyond the tracks. An enlarged view of theend stop bracket 92 is shown inFigure 9 and it can be seen that it comprises a substantially triangular shapedhousing 98, joiningpins 90 extending outwardly from aninternal bracket plate 100, and astop portion 102 extending between thepins 90 and intochannel 80 when thebracket 92 is mounted to thetrack 12. - The
stop portion 102 includes a plurality ofribs 104 which provide an elastomeric buffer for reducing impact loads. Shelving units when moved generate a significant amount of force due to their weight and therefore require that the track end stops be robust enough to dampen such force upon impact. Theend stop bracket 92 also includesanti-tilt shoulders 106 as per therunner end brackets 38. - The height of the
track 12 also needs to be maintained level along its length. It is also preferable for the height of thetrack 12 to also be easily adjustable even after assembly. One ormore packers 108 shown most clearly inFigure 2 and the cross sectional views, are used to achieve this. Eachpacker 108 is substantially rectangular in shape and includes a 3x2 matrix ofapertures 110 extending there through. One row of threeapertures 110 of thepacker 108 includes elevatedsquare surrounding portions 112. The adjacent row of threeapertures 110 include locating means 111 for engaging the elevatedsquare surrounding portions 112 of asecond packer 108 positioned therebeneath. Each adjacently stackedpacker 108 is rotated by 180 degrees relative to the other. - One or more packers 108 (depending on the desired height) are adapted to sit beneath the joining
pins 90 at the ends of thetrack 12, as well as beneath the joiningpins 88 at one or more joints between track segments. Theapertures 110 are designed to accommodate the head portions of the self-tappingscrews 34 which engage the joiningpins packers 108 could be added or removed to increase or decrease the height of a particular section oftrack 12. - A further advantage to the improved stiffness characteristics of the track extrusion is that it allows for wider spacing of the
packers 108 along thetrack 12. - The
assembly 10 includes a plurality of optionallyattachable ramp sections 114. These are used to provide a smooth surface over thetrack 12 and prevent thetrack 12 from forming a tripping hazard. Eachramp section 114 includes a substantiallyrectangular body 116 having ahook section 118 at one end thereof, and astraight edge 120 at the opposed end adapted to lie substantially flush with the ground when assembled. Theramp section body 116 includes a plurality ofribs 122 on its upper surface for gripping purposes. There are reinforcingmembers 124 positioned below thebody 116 which are advantageous because they reduce the overall weight of the ramp section and maintain strength. Thehook section 118 extends downwardly from thebody 116, then inwardly and upwardly with respect to thetrack 12. - The track extrusion is also designed to accommodate the
ramp sections 114. Turning now toFigures 10-11 , between the lower end of theexternal walls internal walls hook section 118 of eachramp section 114. In particular, eachramp section 114 is configured to engage the receiving channels 125 by way of a rotatable snap-fit. Figure 12 illustrates this process, whereby thehook section 118 is inserted into the receiving channel 125 and then urged upwardly whilerotating edge 120 of the body downwardly until thehook section 118 is snap-fit in place. This ramp pivot geometry is designed to allow removal and refitting of ramps (for re-levelling purposes) without having to lift up or up-end thetrack 12. - A
rubber tube 126 is also inserted between the rounded end of theexternal walls hook section 118. Thetube 126 provides a down-force and minimises ramp "kick-up" which could create a tripping hazard. A further advantage to therubber tube 126 is that it also acts as a flexible joiner, assisting in handling and simultaneous fitting of multiple ramp sections to thetrack 12. - The ramps are optional as the track extrusion has been designed to be aesthetic and safe even if used without
ramps 114. - Finally, the
runner 14 is able to be locked at different positions along thetrack 12. A lockingbracket 40 is shown in the drawings which is also engageable to anupper slot 28 of therunner 14, as well as the side slots, by means described above. The lockingbracket 40 includes ahousing 128 mounted to therunner 14, thehousing 128 defining a vertical chamber extending downwardly alongside therunner 14 to thetrack 12. The chamber includes avertical aperture 130. When the shelving unit is to be locked, the runner is moved along thetrack 12 until thevertical aperture 130 becomes co-axially aligned with anaperture 132 that has been pre-drilled into thetrack 12. Once aligned, alocking pin 134 can be inserted through the co-axiallyaligned apertures hollow region 86 where it rests on thebase 66, thereby locking therunner 14 to thetrack 12. - A
jig 136 is provided for forming thepre-drilled apertures 132 in thetrack 12. Thejig 136 is an elongate structure mountable to thetrack 12 in a transverse arrangement as shown inFigure 1 . Thejig 136 includes a downwardly extendingsection 138 at its centre which extends insidechannel 80, as well as downwardly extendingsections 140 at ends thereof which abut with theexternal walls track 12. On opposed ends of thejig 136 areapertures - The
jig 136 is first adapted to be mounted to thetrack 12 so thataperture 144 is positioned over a desired point to be drilled. The purpose of thissmaller aperture 144 is to mark thetrack 12 with a suitable tool (not shown), the mark acting as a locating guide for a drill bit or the like used to drill a hole through thetrack 12. Thejig 136 is then demounted from thetrack 12, rotated by 180 degrees, and mounted to thetrack 12 again so that thelarger aperture 146 extends over the marked point. A drill (not shown) can then be used to drill a hole through thetrack 12 where marked. - It is to be understood that the design of some of the components shown and described could change where necessary. For example, where there is a mechanical driving means associated with the runner, one of the track
external walls 78 would extend a greater distance outwards from thechannel 80 and include a flat upper surface (not shown) for accommodating a drive wheel (not shown). Such a track would therefore include a furtherhollow region 86. In such circumstances, thesame packers 108 could be used but simply rotated by 90 degrees so that instead of extending longitudinally relative to thetrack 12, it would extend transversely. - Further advantages and improvements may very well be made to the present invention without deviating from its scope. Although the invention has been shown and described in what is conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope of the invention, which is not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent devices and apparatus.
- In any claims that follow and in the summary of the invention, except where the context requires otherwise due to express language or necessary implication, the word "comprising" is used in the sense of "including", i.e. the features specified may be associated with further features in various embodiments of the invention.
