WHEEL RACK ASSEMBLY

[0001] This application claims the benefit of Australian Provisional Patent Application No. 2019901482 (AU 2019901482) that was filed on 1 May 2019. The entire contents of AU 2019901482, as originally filed, are incorporated herein by reference.

FIELD OF THE INVENTION

[0002] This present invention relates to a wheel rack assembly for releasably securing a wheel, such as a bicycle wheel, for transporting and/or storing the wheel. More particularly, but not exclusively, a preferred example of the present invention relates to a bicycle rack assembly for releasably securing a bicycle when transporting and/or storing the bicycle by releasably securing a wheel of the bicycle.

BACKGROUND

[0003] Bicycle racks may be used to transport and store bicycles. The racks are typically arranged to releasably engage a frame or wheel rim(s) of a bicycle to securely retain the bicycle in place during transport and/or storage. The racks may be secured, for example, to the roof of a vehicle (such as via roof racks), to the floor or deck of a vehicle (such as a utility vehicle or trailer), or to the rear of a vehicle (such as via a tow bar/tow ball).

[0004] Previously proposed racks typically have one or more drawbacks. For example, some racks that are arranged to releasably clamp or engage the frame or rims of a bicycle can damage the bicycle, and are normally cumbersome and slow to use when securing and/or releasing a bicycle. Further, some racks are not readily adjustable to accommodate different size bicycles. Further, some racks do not securely retain the bicycle, and in consequence may allow movement during transport, again potentially risking the bicycle being damaged.

[0005] It would be desirable to provide a bicycle rack assembly that facilitates efficient, secure fastening of a bicycle to a vehicle, such as a car or trailer, for transport and/or storage preferably without damaging the bicycle, and preferably with minimal or only small adjustment of the assembly and/or the bicycle required.

[0006] An embodiment of the present invention seeks to at least provide the public with a useful choice.

DETAILED DESCRIPTION

[0036] A wheel rack assembly, or device or apparatus, 10 for releasably securing a wheel 12, such as a bicycle wheel, according to a first example of the present invention is shown in Figures 1-6. The assembly 10 may be used for transporting and/or storing the wheel 12 (not shown in Figures 2 and 3 for clarity). Preferably, the assembly 10 is, or is part of, a bicycle rack assembly for releasably securing a bicycle when transporting and/or storing the bicycle. Alternatively, the assembly 10 may be configured to securely retain another type of vehicle that has two wheels 12, such as a motorcycle, scooter, etc., that are normally generally located in a single plane that is substantially perpendicular to a centre axis of each of the wheels 12.

[00371 The wheel rack assembly 10 may by mounted and/or secured, for example removably mounted and/or secured, to a vehicle (not shown) for transporting a bicycle. The assembly 10 may be mounted to the rear of a passenger automotive vehicle. Alternatively, the assembly 10 may be mounted to a deck or floor, and/or one or more side walls, of a vehicle, such as a utility vehicle, a van, a truck or a trailer. Alternatively, the wheel rack assembly 10 may by mounted and/or secured to a substantially horizontally-extending floor, one or more vertically-extending walls, and/or other structure of a building or other structure for storing a wheel 12 and/or bicycle. For example, the assembly 10 may be secured relative to a floor of a shop or a garage for storage and/or display of a bicycle.

[00381 The wheel rack assembly 10 comprises support structure, or portion or member, 14 arranged to at least partly support a wheel 12, a lever or arm, or similar member, 16 that is pivotally mounted relative to the support structure 14 via a pivot 18, and biasing means in the form of at least one biasing member 20 arranged to resiliently bias or urge the lever 16.

[0039] The support structure 14 comprises or is a receptacle 22 (not shown in Figure 1), or wheel well, or one or more brackets, for receiving a circumferential section of a wheel 12. The receptacle 22 comprises a generally planar base 24, and spaced apart sides 26, 28 and spaced apart ends 30, 32. The sides 26, 28 are substantially parallel to each other, and each extends in a plane that is substantially perpendicular to a pivot axis 34 of the pivot 18. The pivot axis 34 is typically substantially parallel to a centre axis 37 of a wheel 12 supported in the receptacle 22 in situ. Preferably, with reference to Figure 6, one or both of the sides 26, 28 may each comprise two spaced side sections 36, 38 with a gap in between. The ends 30,32 diverge away from each other, in a direction away from the base 24, such that the receptacle 22 has a substantially elongate opening 39 for receiving a circumferential section of a wheel 12, an area of the opening 39 being larger than an area of the base 24 inside the receptacle 22. With reference to Figure 2, a longitudinal or side cross-section of the receptacle 22 has a substantially trapezoidal shape. It will be understood the receptacle or wheel well 22 may be different shapes and/or sizes. For example, one or both of the sides 26, 28 may each be inclined relative a plane that is substantially perpendicular to the pivot axis 34. For example, the sides 26, 28 may diverge outwardly away from each other in a direction away from the base 22, similar to the ends 30, 32. Further, although the base 24, sides 26, 28 and ends 30, 32 are substantially planar members (as shown in Figures 1-3), it will be understood one or more of each of the sides 26, 28, and/or the base 24 and the ends 30, 32 may be each be substantially arcuate or other shape members. For example, the ends 30, 32 maybe shaped to correspond to the round outer profile of the wheel 12.

[0040] The receptacle 22 may be configured to at least partly receive and support a range of different size, including different width and/or diameter, wheels 12. For example, the base 24 may have an arcuate upper surface that corresponds to a circumferential section of a tyre/wheel. Alternatively, the receptacle 22 may be configured to receive and support a wheel 12 that is a predetermined size. Further, a removable insert (not shown) may be provided in the receptacle 22, or wheel well, the insert being configured to preferably snugly receive and support a wheel 12 that is a predetermined size.

[0041] The support structure 14 will typically be secured to a vehicle to transport a bicycle. For example, the receptacle 22 may be mounted to a tray or deck, a roof (such as by using roof racks), or the rear, of a vehicle.

[0042] The lever 16 is pivotally mounted relative to the support structure 14 so that the lever 16 can pivot 18 about the pivot 18 relative to that support structure 14 in a wheel engaging or wheel-securing direction 40 and a wheel-releasing direction 42. The wheel engaging direction 40 is opposite to the wheel-releasing direction 42. The lever 16 pivots or rotates in a plane that is substantially perpendicular to the pivot axis 34.

[0043] The lever 16 is pivotally connected to the support structure 14 at the pivot 18. The pivot 18 extends through a pivot mount 44 that is secured to or forms part of the support structure 14. Preferably, the pivot mount 44 is secured to, and/or generally located at or near, the end 32. Alternatively, the support structure 14 and the lever 16 may be substantially independent components. For example, the support structure 14 may be mounted to a tray or floor associated with a vehicle or building, and the lever 16 may be independently pivotally mounted relative to a vertically-extending side or wall associated with the vehicle or building.

[0044] The lever 16 comprises a first section 46 arranged to engage and push against at least a part of a wheel 12 in situ. Preferably, a length of the lever 16 is predetermined to accommodate a specific size (diameter) wheel 12 or a range of different size wheels 12. For example only, the length of the first section 46 of the lever 16 between the pivot axis 34 and a wheel-engaging portion or section 50 may be about 400 mm - 700 mm, about 450 mm - 650 mm, about 500 mm - 600 mm. By way of non-limiting example only, the length of the first section 46 may be about 600 mm-650 mm (for use with a typical mountain /road bicycle), or about 450 mm -550 mm, about 500 mm (for use with a smaller bicycle). Alternatively, the first section 46 may have a length of about 400 mm (for use with a BMX and/or child's bicycle). The lever 16 has a fixed length. Alternatively, the length of the lever may be selectively adjustable to accommodate different size wheels 12. A length of the first section 46 from the pivot 18 to the other end of thefirst section 46 that engages the wheel 12 may be adjustable. For example, the first section 46 may be a telescoping member that can be releasably locked at a desired length to suit a particular wheel diameter. Preferably, the lever 16 also comprises a second section 48 connected to the biasing member 20. Preferably, pivot 18 is generally located, relative to the lever 16, intermediate or between the first section and the second section. Alternatively, the pivot may be located at or near an end of the lever 16, and/or the first 44 section may be connected to the biasing member 20.

[0045] With reference to Figure 3, the lever 16 generally has a u-shape, and comprises the wheel-engaging portion or section 50 arranged to push against a circumferential section of a wheel 12 when the lever 16 is pivoted in the wheel-engaging direction 40 to releasably clamp the wheel 12. With reference to Figures 1 and 3, the wheel-engaging portion 50 extends at least partly in a direction transverse to a radial direction of the wheel 12 so as to extend or wrap laterally across the circumferential section of the wheel 12. The wheel-engaging portion preferably comprises a curved or arcuate section, or two or more curved or arcuate sections arranged in series and optionally spaced apart by one or more straight sections, so as to substantially conform to an outer surface of a tyre of a wheel 12, such as a bicycle tyre, having a generally curved outer profile or tread. Alternatively, the wheel-engaging portion 50 may be other shapes.

[0046] The lever 16 further comprises at least one arm 52, 54 that extends between the wheel-engaging portion 50 and to or near, or past, the pivot. Preferably, the lever 16 comprises two spaced arms 52, 54. A first elongate arm 52 extends between the wheel engaging portion 50 and to or near the pivot 18, and a second elongate arm 54 substantially extends past the pivot 18 to define the second section 48 that is pushed (or alternatively pulled) by the biasing member 20. The wheel-engaging portion 50 extends laterally between ends of the arms 52, 54. The two arms 52, 54 converge towards each other in a direction from the pivot 18 towards the wheel-engaging portion 50. Alternatively, the arms 52, 54 may extend in substantially parallel directions relative to one another.

[00471 With reference to Figure 2, the wheel-engaging portion 50, or the arms 52, 54, or both the portion 50 and the arms 52, 54, may extend in a plane that is substantially perpendicular to the pivot axis 34 of the pivot. The lever 16 may be formed from a unitary part. For example, the lever 16 comprising the wheel-engaging portion 50 and the arms 52, 54 may be formed by bending a rod or similar elongate member, or by casting or moulding. Alternatively, the lever 16 may be formed from two or more components that are secured relative to, such as welded or similarly fastened to, one another. It will be understood the lever 16, including the wheel-engaging portion 50, may be other shapes.

[0048] Preferably, the lever 16 comprises a recess for receiving at least part of a wheel 12 when the lever 16 is pivoted in the wheel-engaging direction 40 to releasably clamp the wheel 12. The recess may comprise or be an opening 56 substantially located intermediate and/or between the wheel-engaging portion 50, the arms 52, 54 and the pivot 18. Alternatively, the recess may be formed in a body of the lever 16, such as in the form of a scoop, or similar cavity or depression, formed in a body of the lever 16 for receiving a circumferential section of a wheel 12.

[0049] The biasing member 20 is arranged to resiliently bias or urge the lever 16 in the wheel-engaging direction 40 to releasably clamp a wheel 12 relative to the support structure 14. Preferably, a first end or portion 58 of the biasing member 20 is pivotally connected to at least one of the arms 54, at a location spaced from the pivot 18 in a direction substantially perpendicular to the axis 34 of the pivot 18. Preferably, the biasing member 20 is configured to resiliently push the lever 16 in the direction 40. Alternatively, biasing member 20 may be configured to resiliently pull the lever 16 in the direction 40. A second end or portion 60 of the biasing member 20 is pivotally connected to the support structure 14, such as a side 26 of the receptacle 22. Alternatively, the second end 60 of the biasing member 20 may be secured to other structure, such as an underlying surface of a transport vehicle on which the support structure 14 is mounted.

[0050] The biasing member 20 comprises or is a spring, such as a gas spring (for example, a "gas strut"). For example, the may comprise compressed gas contained within an enclosed cylinder, or similar chamber, sealed by a sliding piston and arranged to pneumatically store potential energy and withstand external force applied in a direction parallel to a direction of a shaft of the piston.. Alternatively, the biasing member 20 may comprise or be a mechanical spring. The mechanical spring may comprise, for example, a compression spring, an extension spring or a torsion spring. Preferably, the biasing member is a generally elongate member that longitudinally extends and resiliently retracts in a direction that is substantially perpendicular to the pivot axis 34. It will be understood the assembly 10 may comprise two or more biasing members 20, arranged to operate in series and/or parallel.

[0051] The use of the rack assembly 10 to securely fasten and releasably retain a bicycle for transport or storage will now be described. In Figures 1 and 4-6, the assembly 10 is shown being used to securely, releasably retain a wheel 12 (rest of the bicycle not shown).

[0052] The lever 16 is pivotally retracted about the pivot 18 in the wheel-releasing direction 42, against the resilient bias of the biasing member 20, to provide access to the receptacle 22. In one example, the lever 16 may be pivotable about the pivot 18 in the wheel releasing direction 42 to or past an over-centre location (not shown) such that the biasing member 20 resiliently biases the lever 16 in the wheel-releasing direction 42 to inhibit the lever 16 pivoting in the wheel-engaging direction and preventing or inhibiting access to the receptacle 22. Preferably, the assembly 10 further comprises a locking arrangement (discussed below) for releasably locking the lever 16 relative to the support structure 14. The locking arrangement can be used to prevent or at least inhibit the lever 16 pivoting in the wheel-engaging direction 40.

[0053] With the lever 16 in a retracted position, a circumferential section of a (front or rear) wheel 12 of a bicycle is located or positioned in the receptacle 22 such that receptacle 22 preferably at least partly receives and supports the wheel 12. Preferably, the receptacle 22 substantially retains and holds the wheel 12/bicycle such that the bicycle will stand in a substantially upright orientation without the operation of the lever 16, and without any extra support, so that an operator's hands are free to operate lever 16.

[0054] The locking arrangement (if present) is unlocked, and/or the lever 16 manually released, so that the lever 16 will pivot 18 in the direction 40, under the action of the biasing member 20, to releasably clamp the wheel 12 (and bicycle) relative to the support structure

14. It will be understood that if the lever 16 has been previously been pivoted to an over centre location, the lever 16 may need to be manually pivoted back past the over-centre location, against the bias of the biasing member 20, before the biasing member 20 will resiliently urge the lever 16 in the clamping direction to releasably clamp the wheel 12 relative to the support structure 14.

[0055] As the lever 16 moves in the wheel-engaging direction 40, a circumferential section of the wheel 12 is received or passes through the opening 56. The wheel-engaging portion 50 engages and pushes against a circumferential section of the wheel 12, and clamps the wheel 12 relative to the support structure 14 (shown in Figures 1, 4-6). The clamping action of the lever 16 preferably inhibits movement of the wheel 12, and the rest of the bicycle connected to the wheel 12, laterally in directions substantially parallel to the centre axis 37 of wheel 12 and the pivot axis 34, and also in directions substantially perpendicular to the centre axis 37 of the wheel 12 and the pivot axis 34, relative to the support structure 14/receptacle 22.

[0056] Advantageously, the biasing member 20 exerts a force on the lever 16 at a location spaced from the pivot 18, causing the lever 16 to close (in the direction 40) and apply a preferably substantially even force or pressure to the wheel 12, releasably clamping and securing the wheel 12 in place. The position of the biasing member 20 can be predetermined to apply more or less force to the lever 16, or a more- or less-pressurised gas strut can be used to apply more or less force to the lever 16. Advantageously, the biasing member 20 will continuously apply a clamping force or pressure to the wheel 12 to prevent movement during transport and/or storage, even if an outer tyre of the wheel 12 on which the lever 16 presses deflates during transport and/or storage.

[00571 A locking arrangement (discussed below), where present, may then be used to releasably lock the lever 16 relative to the support structure 14 to securely retain the bicycle relative to the support structure 14. If necessary, one or more tie-downs or other fastening elements, such as rope, straps, bungee cords, may also be used to tie down and/or fasten the bicycle to the vehicle (not shown).

[0058] It will be understood the wheel rack assembly 10 may be arranged to securely retain multiple bicycles, typically arranged side-by-side such that the clamped wheels of the bicycles extend in substantially parallel planes. For example, the support structure 14 may have a plurality of adjacent and/or substantially parallel receptacles 22 each arranged to at least partly receive and support a wheel 12 of a respective bicycle. The assembly 10 may comprises a single lever 16 configured to engage and clamp multiple wheels relative to the support structure 14, or multiple discrete levers configured to each engage and clamp a respective wheels 12 to the support structure 14.

[0059] Advantageously, the assembly 10 is relatively quick to use to fasten a bicycle, requiring only small, if any, adjustment of the assembly 10 and/or bicycle. Further, because the assembly 10, including the structure 14 and the lever 16, may only contact an outer tyre of a wheel 12 of the bicycle the assembly 10 is unlikely to damage the bicycle.

[0060] Preferably, the assembly 10 further comprises a locking device (not shown) configured to selectively prevent or at least inhibit removal of the bicycle (e.g. theft) from the assembly 10. For example, the locking device may be arranged to engage a frame or a wheel 12 of the bicycle. Alternatively, the locking device may be arranged to prevent the lever 16 pivoting in the wheel-releasing direction 42 relative to the receptacle 22 when a bicycle wheel 12 is secured.

[0061] The assembly 10 may be manufactured from any suitable material or materials. For example, the assembly 10 may be formed from metal, such as steel and/or other alloys, plastics, and/or carbon fibres.

[0062] Although the assembly 10 has generally been described above and shown in Figures 4-6 when used above and/or secured to a substantially flat horizontal surface, it will be appreciated that base 24 of the receptacle 22 may be inclined relative to a horizontal or vertical surface in situ. By way of non-limiting example only, the substantially planar base 24 may be inclined to substantially extend in a plane at that makes an angle of anywhere in the range of 0-90 degrees, including 0 or 90 degrees, to a horizontal plane. For example, the base 24 may be inclined to substantially extend in a plane at that makes an angle of about 30-60 degrees, say about 45 degrees, to a horizontal plane.

[0063] By selecting the relative spacings, and/or distances, between each of the pivot axis 34, the centre axis 37 of a predetermined wheel 12 in situ, and the length of the lever 16, advantageously the assembly 10 can be readily used to secure various size wheels 12 without substantive adjustment. To facilitate this, the location of the pivot 18 may be adjustable relative to at least part of the support structure 14, such as the receptacle 22.

[00641 A universal wheel rack assembly 110 according to a second example of the present invention is schematically shown in Figures 7(a) - (b). The assembly 110 is similar to the assembly 10 of the previous example described with reference to Figures 1-6. Unless otherwise described, reference numerals with the addition of 100 indicate like features of the assembly 10 previously described with reference to Figures 1-6.

[00651 The support structure 114 of the assembly 110 is adjustable between at least a first configuration for at least partly supporting a first wheel, and a second support configuration for at least partly supporting a second wheel, a size of the first wheel being different to a size of the second wheel. For example, the first configuration may be for at least partly receiving or supporting wheel having a smaller or larger diameter (relative to the second configuration). Alternatively, the first configuration may be for at least partly receiving or supporting a narrower or wider wheel (relative to the second configuration).

[0066] The support structure 114, instead of a receptacle, comprises spaced apart first and second brackets 162, 164 arranged to at least partly support respective, circumferentially spaced sections of a wheel (not shown in Figures 7(a)-(e)) in situ. The brackets 162, 164 are each shaped to at least partly retain or support the respective wheel section by inhibiting movement in directions substantially perpendicular to the pivot axis 134, and laterally in directions parallel to the pivot axis 134. Each of the brackets 162, 164 comprises a rail 166, or portion or member, for inhibiting movement of a wheel in directions substantially perpendicular to the pivot axis 134, and spaced, parallel sides 168, 170 for inhibiting movement laterally in directions parallel to the pivot axis 134. The second bracket 164 further comprises a substantially planar base 172 arranged to at least partly support a wheel, such as the bottom of the wheel. The base 172 extends in a direction away from the rail 166 of the second bracket 164 towards the first bracket 162.

[00671 The first bracket 162 is movable relative to the second bracket 164 in directions substantially perpendicular to the pivot axis 134, away and towards the second bracket 164, to adjust the support structure 114 between the first configuration and the second configuration. Preferably, the first bracket 162 is slidably mounted on a track 174 that extends in a direction substantially perpendicular to the pivot axis 134. The track 174 may be mounted on or secured to an underlying surface or structure, such as a tray, or floor or deck, of or associated with a vehicle, or a roof (such as via roof rack(s)) of or associated with a vehicle. Preferably, the first bracket 162 is releasably lockable relative to the track 174 to prevent movement of the first bracket 162 relative to the track 174 and/or the second bracket 164, and/or the pivot 118. Preferably, the second bracket 164 is slidably mounted on the track 174. Preferably, second bracket 164 is releasably lockable relative to the track 174 to prevent movement of the second bracket 164 relative to the track 174 and/or the first bracket 162, and/or the pivot 118. Alternatively, one or both of the brackets 162, 164 may be fixedly mounted to the track 174 such that the bracket 162, 164 does not move relative to the track 174. By moving the brackets 162, 164 away/towards one another a wheel resting on and/or retained between the brackets may be supported lower/higher relative to the pivot 18.

[00681 A wheel rack assembly 210 according to a third example of the present invention is schematically shown in Figures 8(a) - (b). The assembly 210 is similar to the assembly 10 of the example described with reference to with reference to Figures 1-6. Unless otherwise described, reference numerals with the addition of 200 indicate like features of the assembly 110 previously described with reference to with reference to Figures 1-6.

[00691 The support structure 214 is slidably mounted on a track 262 that extends in a direction perpendicular to the pivot axis 234.

[00701 The support structure 214 comprises a single bracket 264, which is substantially the same as the bracket 164 shown in Figures 8(a)-(e) described above.

[00711 A wheel rack assembly 310 according to a further example of the present invention is schematically shown in Figures 9(a) - (b). The assembly 310 is similar to the assembly 10 of the example described with reference to Figures 1-6. Unless otherwise described, reference numerals with the addition of 300 indicate like features of the assembly previously described with reference to with reference to Figures 1-6.

[0072] The support structure or frame 314 of the assembly 310 comprises a bracket 364 that is substantially the same as the bracket 164. The bracket 364 further has side rails that extend in a plane that is generally parallel to the sides 374, 376.

[00731 The assembly 310 further comprises a locking arrangement 362 for releasably locking the lever 316 relative to the support structure 314 to prevent, or at least inhibit, the lever moving relative to the structure 314. The arrangement 362 can be used to releasably lock the lever 316 in at least a first position relative to the support structure 314 to prevent or at least inhibit the lever 316 pivoting in the wheel-releasing direction 342 (and optionally also the wheel-engaging direction 340) and securely retain the bicycle relative to the support structure 314. Advantageously, the arrangement 362 prevents the lever 316 arm releasing a secured wheel 12/bicycle during transport. Alternatively or additionally, the arrangement 362 can be used to releasably lock the lever 316 in a second position, different to the first position, to prevent or at least inhibit the lever 316 pivoting in the wheel-engaging direction 340 (and optionally also the wheel-releasing direction 342) and thereby preventing or inhibiting an operator positioning a wheel relative to the support structure 314.

[0074] The locking arrangement 362 comprises cooperating features, preferably cooperating male and female features in the form of at least one protrusion or member 370 and at least one corresponding arcuate-shaped opening or slot 372. Preferably, the slot 368 and protrusion 370 are each located towards or near the pivot 318. The support structure 314, and or the pivot 318, comprises or is associated with the protrusion 370 that substantially extends or protrudes in a direction parallel to the pivot axis 334 from a side 374 of the bracket 364. The lever 316 comprises or is associated with the slot 372. In the example assembly 310, an arm 352 of the lever 316 is secured to a plate 368 and the slot 372 is formed in the plate 368. The plate 368 and slot 372 extend in a plane that is substantially perpendicular to the pivot axis 334. The protrusion 372 extends or protrudes through the slot 368. The protrusion 370 may be releasably fastened or secured relative to the plate 368 to prevent movement of the protrusion relative to the plate 368/slot 372 and thereby releasably lock, and prevent pivoting of, the lever 316 relative to the support structure 314. For example, the protrusion 370 may have a threaded end portion so that a nut, such as a wing nut, can be tightened against the plate 368. The example lever 316 comprises two spaced apart, parallel plates 368 each connected to a respective arm 352, 354, and each with a slot 372 that cooperates with a respective protrusion 370.

[00751 It will be understood the assembly 310 may comprises another suitable locking arrangement. For example, the slot 372 that receives the protrusion 370 may be provided on or associated with the support structure 314, and the protrusion 370 may be provided on or associated with the lever 316. Alternatively, the lever 316 and the support structure 314 may each comprise a plate, or similar portion or feature, that extends in a direction substantially parallel to the pivot axis 334 and having an opening or hole, preferably a series of discrete openings or holes that generally follow an arcuate-shaped path, similar to the slot 372. When openings of the substantially parallel, adjacent plates align with each other, a locking pin (not shown) can be removably inserted through the aligned openings to releasably lock the lever 316, relative to the support structure 314, in position.
