Description
2 IMPROVEMENTS IN, OR RELATED TO, BICYCLE CARRIERS
TECHNICAL FIELD OF THE INVENTION
The present invention relates to bicycle carriers.
In particular, though not solely, the present invention is directed to a bicycle rack that can carry a bicycle in an upright or laid-over position.
BACKGROUND OF THE INVENTION
The modern bicycle in its many forms can be difficult to carry.
An advantage of carrying bicycles on the rear of a vehicle, for example by using a load carrier mounted to a towbar or hitch, is ease of loading and unloading.
However, when loaded onto the back of a vehicle, it can leave the bicycle vulnerable in a collision from the rear. Also as it is at road level it is easier for people to tamper with the bicycle or steal it.
A further disadvantage of loading on the back of a vehicle is the bikes are in the aerodynamic wake of the vehicle, therefore they will collect dust and road grime from the vehicle and road. A further disadvantage is that access to the boot area of the vehicle is prevented or compromised, unless the additional complexity, and cost of a tilting rear carrier is added.
An advantage of carrying bicycles on the roof of a vehicle, for example by using a load carrier mounted from the root is the security from tampering, or from an accident, as the bicycle is up high. However, this mode of carrying has the disadvantage of making the vehicle higher than normal such that is cannot fit into most carparks or garages. A further disadvantage is potential damage to the bicycle should the driver forget the bicycle is mounted to the roof and then drives into a garage or carpark. This can damage both the bicycle and the car, and possibly the garage or carpark building. A further disadvantage is the increased aerodynamic resistance of the upright bicycle, which will increase fuel consumption.
In this specification where reference has been made to patent specifications, other external documents, or other sources of information, this is generally for the purpose of providing a context for discussing the features of the invention. Unless specifically stated otherwise, reference to such external documents is not to be construed as an admission that such documents, or such sources of information, in any jurisdiction, are prior art, or form part of the common general knowledge in the art.
It is an object of the present invention to provide an improved bicycle carrying rack, or to overcome the above shortcomings or address the above desiderata, or to at least provide the public with a useful choice.

The hinge 25 allows the fork mounting portion 5 to pivot from the first position 8 shown in Figure 5 through to the second position
11
12 shown in Figure 7 (and the midway position as shown in Figure 6) about the first axis 6.
Rotationally mounted from fork mounting portion 5 is the fork receiving portion 7. The fork receiving portion 7 can rotate relative the fork mounting portion 5 about the second axis 11 as shown in Figures 5 through 7. The fork receiving portion may have differing lengths available or be adjustable between where it attaches to the fork and where it rotates about the second axis 11, to allow for varying fork offsets.
The rotation of the fork receiving portion 7 relative to the fork mounting portion in the preferred form is controlled at least as it moves from the first position (Figure 5) to the second position (Figure 7), and any position there-between by a motion control apparatus 21. The preferred form is shown in detail in Figures 5 through 7 and consists of a crank member 43 mounted on the fork mounting portion 5, or similar moving portion, for example the elongate connecting member 18, via a rotatable mount 44. In the preferred form the crank member 43 is a bell crank as shown. The rotatable mount is ideally a low friction one, and may use roller bearings, low friction materials or similar.
In the preferred embodiment the rotatable mount rotates about an axis parallel to the second axis 11, at least when at or near the first position 8. A first cranking connector 45 pivotally connects at one end to the load carrier 3, or similar stationary component, for example the first mounting portion 2 or similar. The other end connects to a first eccentric location 46 on the crank member 43. A second cranking connector 47 has a first end that connects between a second eccentric location 48 on the crank member 43 and a second end that connects to a third eccentric location 49 on the fork receiving portion.
The effect when the fork mounting portion 5 and fork receiving portion 7 rotate from the first position 8 to the second position 12 is the first cranking connector 45 drives the crank member 43 to rotate. This in turn drives the second cranking connector 47 which in turn drives the fork receiving portion 7. Thus, when moving from the first position 8 to the second position 12 the fork receiving portion 7 is rotated.
A further variation of the bicycle carrying rack 1 is shown in Figures 9 through 11. The rack 1 uses a crank member 43 pivoted on a rotatable mount 44. However the variation shown here varies in that the rotatable mount 44 runs through an edge point of the crank member 43 when compared to the embodiment shown in Figures 5 through 7. Its function however, is the same as that shown in Figures 5 through 7.
The first cranking connector 45 connects between the first mounting portion 2, or similarly stationary components, and a first eccentric location 46 on the crank member 43. A
second cranking connector 47 connects between the second eccentric location 48 on the crank member 43 and the third eccentric location 49 on the fork receiving portion 7. The effect being a rotation of the fork receiving portion 7 when the rack 1 moves from the first position 8 to the second position 12 as earlier described, and vice versa.
Shown in Figure 6 is an energy dissipation device 20. This may be gas, hydraulic or other device that damps motion and may also have a biasing component to it (for example a compressed gas or spring). In Figures 1 through 4 the device 20 acts below the first axis 6, and in Figures 5 through 8 through it acts above the first axis 6. In one form as shown in Figures 1 through 4 the device has a mount 28A separate from the first mounting portion 2. However in Figure 8 it is shown having a mount 28B integrated with the first mounting portion 2. In the preferred form the energy dissipation device 20 urges the fork mounting portion 2 to or towards the first position to resist the natural weight of the bicycle 23, and damps motion in both directions, but preferably when moving from the first position to the second position. This helps control lying the bicycle 23 to or towards the second position so it moves gradually, and helps counteract the weight of the bicycle 23 when moving back to the first position.
Present also is a lock 13, as shown in Figure 3. The lock retains the fork mounting portion 5 (and bicycle 23 if mounted) in the first position. When unlocked it allows the carrier to move from the first position to the second position. In the preferred form the lock 13 acts between the first mounting portion 2 and the fork mounting portion 5, though any way to lock rotation is acceptable. In one form the lock 13 consists of slot in the fork mounting portion 5 which receives a complimentary lock bolt from the first mounting portion 2 which pivots into the slot to lock, and out of the slot to unlock.
When tightened down the lock 13 holds the fork mounting portion 5 to the first mounting portion 2 so the two cannot move relative each other. Should a user desire to move to the second position the lock bolt 30 for example is undone and can then pivot out of the slot 29 to allow movement to or toward the second position. The lock is preferably at least resilient enough to hold the carrier in the first position when a bicycle 23 is mounted there on and carried by the vehicle.
The fork 9 of the bicycle 23 is held by the fork receiving portion 7. In the preferred form this is a clamping of the dropouts of the fork 9 by the wheel axle passing through a wheel
Rotationally mounted from fork mounting portion 5 is the fork receiving portion 7. The fork receiving portion 7 can rotate relative the fork mounting portion 5 about the second axis 11 as shown in Figures 5 through 7. The fork receiving portion may have differing lengths available or be adjustable between where it attaches to the fork and where it rotates about the second axis 11, to allow for varying fork offsets.
The rotation of the fork receiving portion 7 relative to the fork mounting portion in the preferred form is controlled at least as it moves from the first position (Figure 5) to the second position (Figure 7), and any position there-between by a motion control apparatus 21. The preferred form is shown in detail in Figures 5 through 7 and consists of a crank member 43 mounted on the fork mounting portion 5, or similar moving portion, for example the elongate connecting member 18, via a rotatable mount 44. In the preferred form the crank member 43 is a bell crank as shown. The rotatable mount is ideally a low friction one, and may use roller bearings, low friction materials or similar.
In the preferred embodiment the rotatable mount rotates about an axis parallel to the second axis 11, at least when at or near the first position 8. A first cranking connector 45 pivotally connects at one end to the load carrier 3, or similar stationary component, for example the first mounting portion 2 or similar. The other end connects to a first eccentric location 46 on the crank member 43. A second cranking connector 47 has a first end that connects between a second eccentric location 48 on the crank member 43 and a second end that connects to a third eccentric location 49 on the fork receiving portion.
The effect when the fork mounting portion 5 and fork receiving portion 7 rotate from the first position 8 to the second position 12 is the first cranking connector 45 drives the crank member 43 to rotate. This in turn drives the second cranking connector 47 which in turn drives the fork receiving portion 7. Thus, when moving from the first position 8 to the second position 12 the fork receiving portion 7 is rotated.
A further variation of the bicycle carrying rack 1 is shown in Figures 9 through 11. The rack 1 uses a crank member 43 pivoted on a rotatable mount 44. However the variation shown here varies in that the rotatable mount 44 runs through an edge point of the crank member 43 when compared to the embodiment shown in Figures 5 through 7. Its function however, is the same as that shown in Figures 5 through 7.
The first cranking connector 45 connects between the first mounting portion 2, or similarly stationary components, and a first eccentric location 46 on the crank member 43. A
second cranking connector 47 connects between the second eccentric location 48 on the crank member 43 and the third eccentric location 49 on the fork receiving portion 7. The effect being a rotation of the fork receiving portion 7 when the rack 1 moves from the first position 8 to the second position 12 as earlier described, and vice versa.
Shown in Figure 6 is an energy dissipation device 20. This may be gas, hydraulic or other device that damps motion and may also have a biasing component to it (for example a compressed gas or spring). In Figures 1 through 4 the device 20 acts below the first axis 6, and in Figures 5 through 8 through it acts above the first axis 6. In one form as shown in Figures 1 through 4 the device has a mount 28A separate from the first mounting portion 2. However in Figure 8 it is shown having a mount 28B integrated with the first mounting portion 2. In the preferred form the energy dissipation device 20 urges the fork mounting portion 2 to or towards the first position to resist the natural weight of the bicycle 23, and damps motion in both directions, but preferably when moving from the first position to the second position. This helps control lying the bicycle 23 to or towards the second position so it moves gradually, and helps counteract the weight of the bicycle 23 when moving back to the first position.
Present also is a lock 13, as shown in Figure 3. The lock retains the fork mounting portion 5 (and bicycle 23 if mounted) in the first position. When unlocked it allows the carrier to move from the first position to the second position. In the preferred form the lock 13 acts between the first mounting portion 2 and the fork mounting portion 5, though any way to lock rotation is acceptable. In one form the lock 13 consists of slot in the fork mounting portion 5 which receives a complimentary lock bolt from the first mounting portion 2 which pivots into the slot to lock, and out of the slot to unlock.
When tightened down the lock 13 holds the fork mounting portion 5 to the first mounting portion 2 so the two cannot move relative each other. Should a user desire to move to the second position the lock bolt 30 for example is undone and can then pivot out of the slot 29 to allow movement to or toward the second position. The lock is preferably at least resilient enough to hold the carrier in the first position when a bicycle 23 is mounted there on and carried by the vehicle.
The fork 9 of the bicycle 23 is held by the fork receiving portion 7. In the preferred form this is a clamping of the dropouts of the fork 9 by the wheel axle passing through a wheel
13 axle receiving portion 42 on the fork receiving portion. The drop out may be a standard quick release (9 or 10nnnn in diameter), or may be a through axle such as 10nnnn, 12nnnn, 15nnnn or 20nnnn as is known in the bicycle art.
The connection between the fork 9 and the fork receiving portion 7 in the preferred form is one that allows relative rotation between the two. This is because the axis of the headset of the bicycle is not co-linear with the second axis 11. Therefore there needs to be relative rotation between the fork 9 and fork receiving portion 7 to account for this misalignment when moving from the first position 8 to the second position 12 as shown in Figures 8A, 8B and 8C. Alternatively the angle of the second axis 11 may be adjustable to account for this to ensure it is aligned to the axis of the bicycle headset.
In one configuration the fork receiving portion 7 may be mounted directly to the first mount portion via a multi-axis hinge, for example a ball and socket joint This allows rotation about the first axis 6 and second axis 11 and a third axis (perpendicular to the first axis) to account for misalignment of the second axis 11 and the headset axis. The fork mounting portion 5 may still be present if needed in this configuration.
Normally such bicycle carriers also require a further mount to lock the bicycle carrier to the load carrier, for example a pair of roof bars on a vehicle, where the first mounting portion connects to one roof bar of the load carrier 3A and a second mounting portion connects to a second roof bar of the load carrier 3B as shown in Figure 1. To this end the second mounting portion 17 is also pivotally connected to a rear wheel receiving portion 15 of the rack 1. Again this mounting allows pivoting about the first axis 6 via hinge 25B a as shown in Figures 1 through 3. As shown this hinge 25B may simply be a machining out of an extrusion that forms the rear wheel mounting portion 15 and elongate connecting member 18 (described below). Likewise with the first mounting portion 2 there may be an energy dissipation device 20 to also control the rear wheel area - for example if the rear wheel receiving portion is not connected to the fork mounting portion 5, or the bicycle to be carried is heavy, for example an enduro style bike, ore-bike, or a downhill bike.
Alternatively the energy dissipation device 20 may be located on the rear only.
In a preferred form the hinges 25A and 25B are elevated hinges as shown in Figures 1, 9 and 12. The reason for this is to provide greater clearance for the pedals of the bicycle 23 when it is in the second position, so the pedals do not contact the roof of the vehicle 4.

14 The rear wheel receiving portion 15 in the preferred form receives and mounts the rear wheel 31 of the bicycle as shown in Figures 8A and 8B. However, in other forms it may also connect using a bracket or similar to the rear drop outs of the bicycle if needed. In the preferred form the rear wheel receiving portion 15 is channel shaped to accept the rear wheel 31. The rear wheel may be held there using known techniques, such as a strap. In the preferred form the rear wheel receiving portion 15 has an elongate connecting member 18 to connect it to the fork mounting portion 5, such as shown in Figures 5 through 7. The rear wheel receiving portion 15 is also mounted by a hinge 25 mounted to a second mounting portion 17, similar to how the fork mounting portion is to the first mounting portion 2. In this way the rotation movement of the rear wheel receiving portion 15 is controlled to move with the fork mounting portion 5 when moving to and from the first and second positions. This also allows for easy installation and removal and storage of the rack as all the main parts are held together.
A variation of the hinge 25 for the between the first mounting portion 2 and the fork mounting portion 5, and the second mounting portion 27 and the rear wheel receiving portion 15 is shown in Figures 12 through 14. In this case the hinge 25 is an unequal length parallelogram 35. The unequal length parallelogram 35 in the preferred form consists of a base 36 which mounts to the vehicle load carrier, a top 37 which mounts to the fork mounting portion or rear wheel receiving portion, and a short arm 38 and a long arm 39.
In the first position as shown in Figures 12a through 14a the unequal length parallelogram 35 lies substantially flat and as shown largely contained within the base 36, and the bicycle in this orientation would be vertically oriented.
The unequal length parallelogram 35 can them move from the first position in 12a through 14a, the second position shown in 12e, 13g, and 14f in which it is upright In this position the top 37 is now extended and importantly is now at substantially at a right angle to the base 36. In this second position the bicycle will have been rotated through 90 degrees and is now lying in a substantially horizontal position.
In this way the earlier described hinge 25 can be considered a concentric hinge about the first axis 6, and the unequal length parallelogram, whilst also rotating about the first axis 6 does so in a non-concentric manner.
Again like the single axis hinge earlier described fork receiving portion is actuated to rotate the forks from straight ahead in the first position, to approximately 90 degrees in the second position.
5 In use the user mounts the rack 1 in known ways to a load carrier. If necessary to accommodate the bicycle the user may add spacers (not shown) between the rack 1 and the load carrier 3. This may allow for location of a bicycle 23 in the second position 12 without obstructing various components, for example if the pedals of the bike would otherwise strike the roof of the vehicle, then spacers are added to remove or reduce the 10 chance of striking - alternatively as earlier described the hinges 25A
and 25B may allow for this by having an increased height at least when in the second position, such as the unequal length hinge described..
The rack may be configurable to account for the many different load carrier mounting
A variation of the hinge 25 for the between the first mounting portion 2 and the fork mounting portion 5, and the second mounting portion 27 and the rear wheel receiving portion 15 is shown in Figures 12 through 14. In this case the hinge 25 is an unequal length parallelogram 35. The unequal length parallelogram 35 in the preferred form consists of a base 36 which mounts to the vehicle load carrier, a top 37 which mounts to the fork mounting portion or rear wheel receiving portion, and a short arm 38 and a long arm 39.
In the first position as shown in Figures 12a through 14a the unequal length parallelogram 35 lies substantially flat and as shown largely contained within the base 36, and the bicycle in this orientation would be vertically oriented.

In this second position the bicycle will have been rotated through 90 degrees and is now lying in a substantially horizontal position.
In this way the earlier described hinge 25 can be considered a concentric hinge about the first axis 6, and the unequal length parallelogram, whilst also rotating about the first axis 6 does so in a non-concentric manner.
Again like the single axis hinge earlier described fork receiving portion is actuated to rotate the forks from straight ahead in the first position, to approximately 90 degrees in the second position.
5 In use the user mounts the rack 1 in known ways to a load carrier. If necessary to accommodate the bicycle the user may add spacers (not shown) between the rack 1 and the load carrier 3. This may allow for location of a bicycle 23 in the second position 12 without obstructing various components, for example if the pedals of the bike would otherwise strike the roof of the vehicle, then spacers are added to remove or reduce the 10 chance of striking - alternatively as earlier described the hinges 25A
and 25B may allow for this by having an increased height at least when in the second position, such as the unequal length hinge described..
The rack may be configurable to account for the many different load carrier mounting
15 systems presently and in future, that may be available. The mount or mounts 28A, for the energy dissipation device(s), if separate, are mounted also, in the known ways. The rack 1 is locked in the first position.
A user then removes the front wheel of the bicycle 23 and lifts it onto the rack 1. Then in whichever order they prefer they can connect the rear wheel to the rear wheel receiving portion 15 and the fork 9 to the fork receiving portion 7, or vice versa. Once locked to each portion the user can then elect to carry the bicycle in the first position 8, substantially vertically, or may lie the bicycle down in or toward the second position 12.
It should be understood that not all bicycles may adapt to being carried horizontally, they may get near that plane, but not fully lie in that plane for several reasons.
For example they may be too bulky and may have parts that interfere with a component of the load carrier or vehicle, for example a pedal may hit the roof. Other bicycles may not allow full rotation of the fork, for example a downhill bike that has dual triple clamps for the fork, such that the stanchions of the fork hit the frame of the bicycle when rotated.
If they choose to carry in the first position then they are done with loading the bicycle.
If they choose to lay the bicycle at or toward the second position 12 then they simply disengage the lock 13, and allow the bicycle to move in a controlled fashion to the second position 12 - if present then unlocking of the lock bolt 40 (described below) will also be required. This may be done as two separate actions, but it is envisaged the two could be

This may be done as two separate actions, but it is envisaged the two could be
16 undone with one mechanism. As they lie the bicycle over toward the second position the fork receiving portion rotates the fork proportionally. In this way any handlebar 32 of the bicycle 23 is rotated to its least cumbersome position, see Figures 8A to 8B.
When at the desired position the user may lock the bicycle in that position.
Again either using a lock that may hold it at whatever angle is desired, or they may strap a part of the bicycle to one or both of the load carrier roof bars 3A or 3B. For example with a road bike they could strap the seat to the bar 3B, or other support (not shown) from the load carrier 3.
Another form of lock bolt 40 for the bicycle carrying rack 1 is shown in Figures 15 through 18, where like numbers indicate like features from earlier embodiments. In this embodiment the lock bolt 40 locks the relative rotation of the fork receiving portion 7 to the fork mounting portion 5. As seen in Figure 15, and more closely in Figure 16 the lock bolt 40 holds the two in the first position.
The lock bolt 40 in its most simple form is sprung loaded to engage a complimentary recess in the form mounting portion 5. A user may use their hands to disengage the lock bolt 40 from the complimentary recess 41 so the two are free to rotate to or towards the second position as shown in Figure 17. In the embodiment shown there is no complimentary recess for the lock bolt 40 when in the second position.
However, in other embodiments there may be to allow further locking in the second position.
The lock bolt 40 may work independently or in conjunction with the lock 13 earlier described.
In other embodiments the lock bolt 40 may be activated or release by a key, lever or similar release mechanism which may be more easily accessed.
The bicycle is now in, or towards position two where it offers the least wind resistance and more importantly its lowest position to allow access to a garage, carpark or other low overhead location.
To remove the bike, the user undoes the lock of the bicycle in the second position and returns it to the first position, and then reverses the process of securing it to the carrier 1.
They can then mount the front wheel and they are completed.
When at the desired position the user may lock the bicycle in that position.
