Description

VERTICAL CARRY BICYCLE RACK WITH IMPROVED MOUNTING AND SECURING SYSTEM

FIELD OF THE INVENTION

[0001] The present invention relates, in various embodiments, to a vertical carry bicycle rack with an improved mounting and securing system. In some embodiments this provides a hitch-mounted rack for a vehicle.

BACKGROUND

[0002] Any discussion of the background art throughout the specification should in no way be considered as an admission that such art is widely known or forms part of common general knowledge in the field.

[0003] Vertical carry bicycle racks, for example hitch mount racks, have become increasingly popular in recent years, particularly for dual suspension mountain bicycles. Conventionally, bicycles are held in place via two connection points: an upper connection point (for example a front wheel bucket, headtube holder, or the like) and a lower connection point (at which the rear wheel is secured). Known lower connection point arrangements include elastic tethers and the like, which are fiddly to operate and/or result in a low-security mounting (which can lead to a risk of a bicycle becoming dislodged during travel).

[0004] It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.

DETAILED DESCRIPTION

[0046] The present invention relates to bicycle racks, with a focus on vertical carry bicycle racks (including hitch-mount and tow-ball mount racks). Example embodiments are described by reference to the drawings, which are in some cases representative only and not drawn to scale.

[0047] FIG. 1A and FIG. 1 B illustrate a structure for mounting one or more bicycles in substantially vertical, in the form of a vertical carry hitch-mountable bicycle rack 100. Rack 100 is illustrated in a four-bicycle configuration, however it will be appreciated that other embodiments are configured to hold alternate number of bicycles (for example between 1 and 8 bicycles). Other embodiments are configured as structures for purposes other than hitch-mounted arrangements (for example on trailers or the like, or on tow-ball arrangements). FIG. 1A illustrates simplified bicycle outlines.

[0048] Rack 100 includes an attachment member 101 configured to be secured to a vehicle. In this example, member 101 is a hitch-mountable arrangement, for example including a horizontal bar which is secured in a rectangular tow hitch socket. A structure body 102 is configurable to extend substantially vertically from attachment member 101 when the attachment member is secured to the vehicle. In some embodiments the coupling of member 101 to body 102 allows selective adjustment of the angle between those components, for example to allow tilting of the rack (which may allow a car boot door to be opened in some cases).

[0049] An upper support bar 103 is coupled to the structure body. The upper support bar is substantially horizontal when the attachment member is secured to the vehicle. A lower support bar 119 is also coupled to the structure body, wherein the lower support bar is substantially horizontal when the attachment member is secured to the vehicle. In use, these bars are preferably offset vertically such that the lower bar is closer to the vehicle (i.e. the structure body is substantially vertical but inclined away from the vertical .to extend upwards and outwardly from the vehicle).

[0050] The structure includes or more mounting arrangements, wherein each mounting arrangement is configured to receive and secure a respective bicycle.

[0051] Each mounting arrangement includes an upper mounting member 104 which is configured to engage with a first region of the bicycle. In FIG. 1A, member 104 is a wheel receiving member, into which a front wheel 150 is inserted (for example vertically lowered), also known as a “wheel bucket”. This includes an opening into which a wheel is lowered such that the wheel is secured loosely by the opening and the upper support bar (or an adjacent member) under influence of gravity. Alternate upper mounting member types may be used, for example upper mounting members which couple to a headtube region of a bicycle. Upon inserting a front wheel 150 into member 104, the bicycle hangs in a semi-secured fashion with handlebars 151 angled.

[0052] A lower mounting member 105 is configured to engage with a second region of the bicycle, in this example being a rear wheel 152. Member 105 may be a locating member which restricts sideways movement of wheel 152 (for example a pair of flanges between which the rear wheel type/rim region is above to be positioned, also referred to as a rear wheel cradle). It will be appreciated that member 105 may be relatively rudimentary, for example any form of channel into which a tyre is able to rest with lateral movement inhibited upon securing of the bicycle as discussed below.

[0053] A securing mechanism is configured to secure the bicycle with respect to the upper and/or lower mounting member. As discussed below, the mechanism of FIG. 1A secures the bicycle with respect to the rack via a substantially downwards force which biases the first region (front wheel) of the bicycle into secure engagement with the upper mounting member, and also holds the rear wheel in the lower mounting member.

[0054] Further examples of rack 100 are shown in FIG. 4 and FIG. 5, shown in a side view, and corresponding reference numerals are used. A simplified bicycle 160 is illustrated in a mounted position. In the example of FIG. 4, the rack includes an attachment member 101 configured to be secured to a vehicle via a hitch-mountable arrangement. In FIG. 5, the attachment member 101 ’ is for a tow-ball arrangement. Other than differences in the attachment member, the racks of FIG. 4 and FIG. 5 are generally the same.

[0055] A structure body 102 is configurable to extend substantially vertically from attachment member 101 when the attachment member is secured to the vehicle. The coupling of member 101 to body 102 is via a rotating mechanism 180, which allows selective adjustment of the angle between those components, for example to allow tilting of the rack (which may allow a car boot door to be opened in some cases). Rotating mechanism 180 has a foot lever 181 , which allows for the rotating mechanism to transition between a fixed/locked configuration, and rotation-enabled configuration.

[0056] An upper support bar 103 is coupled to the structure body. The upper support bar is substantially horizontal when the attachment member is secured to the vehicle. A lower support bar 119 is also coupled to the structure body, wherein the lower support bar is substantially horizontal when the attachment member is secured to the vehicle. In use, these bars are preferably offset vertically such that the lower bar is closerto the vehicle (i.e. the structure body is substantially vertical but inclined away from the vertical .to extend upwards and outwardly from the vehicle)

[0057] The structure includes or more mounting arrangements, wherein each mounting arrangement is configured to receive and secure a respective bicycle.

[0058] Each mounting arrangement includes an upper mounting member in the form of a wheel bucket 104, which is configured to engage with a front wheel 150 of the bicycle. Front wheel 150 is inserted (for example vertically lowered), also known as a “wheel bucket”. This includes an opening into which a wheel is lowered such that the wheel is secured loosely by the opening and the upper support bar (or an adjacent member) under influence of gravity. Alternate upper mounting member types may be used, for example upper mounting members which couple to a headtube region of a bicycle. Upon inserting a front wheel 150 into member 104, the bicycle hangs in a semi-secured fashion with handlebars 151 angled.

[0059] A lower mounting member 105 is configured to engage with a second region of the bicycle, in this example being a rear wheel 152. Member 105 may be a locating member which restricts sideways movement of wheel 152 (for example a pair of flanges between which the rear wheel type/rim region is above to be positioned). It will be appreciated that member 105 may be relatively rudimentary, for example any form of channel into which a tyre is able to rest with lateral movement inhibited upon securing of the bicycle as discussed below.

[0060] A securing mechanism is configured to secure the bicycle with respect to the upper and/or lower mounting member. As discussed below, the mechanism secures the bicycle with respect to the rack via a substantially downwards force which biases the first region (front wheel) of the bicycle into secure engagement with the upper mounting member (wheel bucket), and also holds the rear wheel in the lower mounting member. Similar securing mechanisms can be used for the racks of FIG. 1 A/1 B, FIG. 4 and FIG. 5, with examples shown in more detail in further figures.

[0061] The securing mechanism includes: a tether (108a, 108b) and a progress capture device 106.

[0062] The tether extends between: a first end 110 that is attachable to a third region of the bicycle; and a second end 109. In the illustrated example the third region of the bicycle is positioned between a pedal body 154 of the bicycle and a crank arm 153 of the bicycle, and the first end 110 of the tether includes a loop that is attached between the pedal body and the crank arm (around a pedal axle).

[0063] Progress capture device 106 is coupled to the lower mounting member 119. In the illustrated examples this is rigidly affixed to the lower mounting member. It should be appreciated that such rigid mounting is far superior to alternate approaches which make use of conventional tiedown straps or the like. For example: (i) this allows for a “straight-pull” arrangement; (ii) the location at which tightening/loosening operations occur remains consistent; and (iii) there are no buckles/latches at movable locations along the tether. In a further embodiment the tether is defined by a tie-down strap secured at one end to the lower mounting bar, with a tie down strap buckle proving the progress capture mechanism at the junction of a tether loop.

[0064] In use the tether extends through the capture device (region 108a of the tether is illustrated upstream of the capture device, region 108b of the tether is illustrated as downstream of the capture device). The capture device is configured such that, when the progress capture device is in an operative configuration, the tether is able to be progressed through the capture device in a first downstream direction via pulling of the second end 109, but restricted from progressing through the capture device in a second upstream direction opposite to the first direction. As a result, in use, when the first end of the tether is secured to the third region of the bicycle, pulling tension on the second end of the tether secures the bicycle with respect to the structure.

[0065] The progress capture mechanism includes an unlocking member, in the form of a handle 107, which is manually manipulated thereby to transition the progress capture mechanism from the operative configuration to an unlocked configuration in which the tether is able to be progressed in the second direction. Handle 107 is biased (e.g. spring loaded) into position to keep the device in the operative configuration in absence of manual interaction. In use, a user pulls handle 107, which temporarily transitions the device into the unlocked configuration, thereby to move the tether in the upstream direction (for example to gain enough slack to loop/unloop end 110 with respect to the pedal/crank connection area).

[0066] Device 106 is preferably mounted to support member 119 rigidly approximately vertically below a location anticipated for a pedal axle.

[0067] It will be appreciated that various forms of known capture release devices may be used, including spring-loaded capture release devices which include a rotating pully having locking teeth/nubs which are able to engage with a tether in the form of a nylon rope.

[0068] In use, with the rack installed on a vehicle, a user lifts a bicycle onto the rack such that the front wheel 150 is lowered into the wheel bucket 104. The user then wraps the loop at end 110 over pedal 154, and pulls end 109 tightly. This serves to secure the bicycle to the rack for the purposes of transportation. Then, to remove the bicycle, the user pulls handle 107, which allows the loop at end 110 to be removed from the bicycle. The bicycle is then lifted from the rack.

[0069] FIG. 2A illustrates as a partial cutaway view a progress capture device according to one embodiment in an operative configuration, and FIG. 2B illustrates the progress capture device in an unlocked configuration. As shown, handle 107 is coupled to a cammed locking member 201 , which is biased into position for the operative configuration by a spring 202. The cammed shape of member 201 prevents upstream movement of the tether. Rotating the lever clockwise releases the tether from member 201 for the unlocked configuration, allowing the tether to be pulled in either direction.

[0070] FIG. 3A illustrates as a partial cutaway view a progress capture device according to a further embodiment in an operative configuration, and FIG. 3B illustrates that progress capture device in an unlocked configuration. As shown, handle 107 is coupled to a cammed locking member 201 , which is biased into position forthe operative configuration by a spring 202. The cammed shape of member 201 prevents upstream movement of the tether. Rotating the lever clockwise releases the tether from member 201 for the unlocked configuration, allowing the tether to be pulled in either direction. In this example, loop 110 is defined via a point of connection 220 between the tether and the lower mounting member 119 (also referred to as a rear wheel bar).

[0071] FIG. 6A, 6B and 6C show a more detailed view of an example attachment member 101 according to one embodiment. This is configured for a tow-bar hitch arrangement, and shows an optional example anti-wobble mechanism. In further embodiments, other anti-wobble mechanisms are used (with various conventional examples being widely used in the art). The illustrated ant-wobble mechanism in itself presents a standalone novel component, and may be used in other hitch-mount scenarios. [0072] Member 101 includes a lower mount part 601 and upper mount part 602. Lower mount part 601 is mounted to a rectangular prismatic hollow beam 631 , which is configured to be received in a tow bar hitch receiver tube 650, as shown in FIG. 6B and FIG. 6B. Upper mount part 602 is configured to be mounted to vertical structure body 102. Parts 601 and 602 are mounted together via a hollow hinge arrangement 606 which is coaxial around an aperture 604.

[0073] A foot lever 605 is coupled to a locating pin 680 mounted to part 602. This locating pin is biased into engagement with locating notches 681 , thereby to prevent rotation of part 601 with respect to part 602. Depressing lever 605 releases locating pin 680 from notches 618, allowing rotation at hinge arrangement 603. This enables pin 680 to be located in different notches, thereby to facilitate positioning of the vertical support of the rack at different angles.

[0074] The anti wobble mechanism is configured to allow a user to reduce internal movement (particularly upwards and downwards) of rectangular prismatic hollow beam 631within tow-bar hitch receiver tube 650.

[0075] The anti-wobble mechanism is defined by a rectangular prismatic hollow body 631 (which may be square in cross section), which is configured to be received in the tow-bar hitch 660. A rocker member 626 is mounted via a rocker pin 633 within the rectangular prismatic hollow body;

[0076] Respective coaxial hitch pin apertures 632 and 653 are formed in the body and the rocker such that, upon insertion of the body into the tow-bar hitch, the respective coaxial hitch pin apertures formed in the body and the rocker are coaxial with corresponding coaxial apertures formed in opposite sidewalls of tow-ball hitch. As such, a hitch pin is insertable though one sidewall of tow-bar hitch, passing through the body and the rocker, and out through the other side of the tow-bar hitch, thereby to secure the body within the towbar received tube.

[0077] A further aperture is formed in the rocker, situated to receive the rocker pin 633 rearwardly of the hitch pin apertures, thereby to enable rocking of the rocker relative to the body. It will be observed that the rocker is shaped to provide a central pivot on its lower face about which the rocking occurs. This is shown best by comparison of FIG. 6B and FIG. 6C.

[0078] Another aperture is formed in the body, this being configured to allow an abutment member 660 of rocker 625 to extend through body 631 and abut with an interior surface of the tow- ball hitch 650 upon one direction of rocking. A tension mechanism, in this example being an antiwobble tensioning bolt 634, is configured to enable tensioning of the abutment member against the interior surface of the tow-ball hitch, thereby to restrict wobbling of the body within the tow-ball hitch. [0079] The illustrated anti-wobble mechanism is particularly advantageous in the sense that tightening a single bolt allows for wobble-reduction. This is farsimplerthan conventional approaches to reducing wobbling of hitch-mounted accessories.

[0080] FIG. 7A and FIG. 7B show a more detailed view of an example attachment member according to one embodiment. This is configured for a tow-ball mount arrangement.

[0081] This example retains the same upper part 602 from the example of FIG. 6A-C; it is only lower part 601 that is replaced with a lower part 701 (to accommodate a tow-ball 703 mounted to a towbar 702, rather than be inserted into a tow bar hitch).

[0082] As best shown in FIG. 7B, a tow-ball clamp member 704 is provided within lower part 701 , this being configured to receive tow-ball 706. Clamp member 704 is configured to operate as a clamshell style clamp upon tightening of a bolt which is inserted into aperture 705. This tightens the clamshell clamping arrangement of claim member 704 around tow ball 703, thereby to prevent removal of tow ball 703 from lower part 701 .

[0083] In a further embodiment, a mount as disclosed in of EP2048034A2, or a mount based on the teachings of that document, may be used.
