Abstract
The invention disclosed is a bicycle carrying rack to mount to a vehicle. The rack has first mounting portion to connect to a load carrier of the vehicle, and a fork mounting portion including a fork receiving portion. The fork mounting portion is rotationally mounted about a first axis from the first mounting portion. The fork receiving portion receives and locks to a fork of the bicycle. The fork mounting portion has, a first position adapted to locate the bicycle in a substantially vertical position, with the fork aligned in a substantially straight ahead position relative a major plane of the bicycle, and a second position adapted to locate the bicycle, in or toward a horizontal position, with the fork aligned at an angle turned away from the substantially straight ahead position. During the movement from the first position to the second position the fork receiving portion rotates about a second axis to rotate the fork away from the substantially straight ahead position, and vice versa when rotated from the second position to the first position. There is also at least one lock to lock the bicycle at least in the first position, so that a bicycle can be carried in either said first position or said second position. By rotating the handle bars away from the car and allow the bike to be mounted in a substantially horizontal form, the bike is essentially closer to the roof of the car. This results in less fuel consumption in the car caused by drag and reduces the potential for the bike to be damaged or collect dust and grime in the wake of the car during transport.

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 roof, 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.

DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments will now be described with reference to Figures 1 through 17.
A bicycle carrying rack 1 is shown for mounting to a load carrier 3 of a vehicle 4 to hold a
bicycle 23 in either an upright (first position) or laid over (second) position as shown in
Figures 1 through 17.
The bicycle carrying rack 1 consists of a first mounting portion 2 which connects to the
load carrier 3 of a vehicle 4 in a known way. For example the load carrier 3 may be the
cross members (shown in Figure 8A) of a roof rack or similar of a vehicle. The first
mounting portion 2 has a connection or connections to allow it to mount to the load carrier.
Pivotally mounted from the first mounting portion 2 is the fork mounting portion 5. As
shown, for example in Figure 5, a hinge 25 is present to pivotally connect the fork
mounting portion 5 to the first mounting portion 2. 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
12 shown in Figure 7 (and the midway position as shown in Figure 6) about the first axis
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. One preferred form of this is to use a flexible tensile member 22 connected between
the first mounting portion 2 and the fork receiving portion 7 via the fork mounting portion 5
referring to Figures 8B, Looking at Figures 8B and 8C the flexible tensile member is
shown preferably connected to the first carrier portion 2. However, any stationary part of
the bicycle rack relative the fork mounting portion 2 and fork receiving portion 7 will
suffice. The flexible tensile member 22 then extends up through and over the bearing
point 26 pivotally located on the fork mounting portion. In the preferred embodiment the
bearing point 26 is a pulley as shown, to reduce friction. However, any device that allows
relative movement of the flexible tensile member 22 will suffice. In the preferred form the
member 22 then continues and connects to the fork receiving portion 7 to bear on it in a
direction tangential to the second axis 11.
The result is that when the fork mounting portion 5 rotates about the first axis 6, from the
first position to the second position, the flexible tensile member 22 pulls on the first
mounting portion 2 and the fork receiving portion 7. As the fork receiving portion 7 can
rotate about the second axis 11, when the flexible tensile member 22 pulls on it the fork
receiving portion 7 will then be caused to rotate.
In the preferred form the member 22 is continuous, but in other forms may be multipart.
Other forms of motion control apparatus may be used also such as geared connections,
or combinations of geared and flexible connections – a person skilled in the art would
understand how such could be implemented. The motion control apparatus as described
in the preferred form controls rotation of the fork receiving portion 7 when moving from the
first position to the second position. However in other forms it may simply allow an
unlocking of the fork receiving portion 7 to allow it to rotate naturally relative to the fork
mounting portion.
In one preferred form there is a biasing means (not shown) to urge the fork receiving
portion 7 rotationally back from the turned position (as shown for example in Figures 8B
and 8C) to the straight-ahead position (for example as shown in Figure 8A). In one
preferred form this biasing means maybe a spring urging this rotation. The spring may be
a spiral wound spring located about the second axis pivot 27, or may be a coil spring in
tension on the other side of the second pivot axis 27 to the flexible connecting member
22. Alternatively it may be a coil spring acting in compression on the same side as the
flexible tensile member 22. In these cases the biasing means acts between the fork
receiving portion 7 and fork mounting portion 5. In another form the flexible tensile
member 22 may be anchored to the fork receiving portion 7 but extend round the second
axis pivot to be acted on by a biasing means. Such biasing means is in tension or
compression and acts on the flexible tensile member and acts against rotation of the fork
receiving portion when moving from the first position to the second, and acts with the
rotation of the fork receiving portion when moving in the opposite direction. In other forms
the flexible tensile member, or another flexible tensile member extends from the fork
receiving portion 7 and is anchored in a location to pull against the fork receiving portion 7
to rotate it when moving from the second position to the first position (in a similar but
opposite way to how the flexible tensile member 22 acts as described above when
causing the fork receiving portion 7 to rotate when moving from the first position to the
second position).
In another form there may be no control of rotation of the fork receiving portion at least
when moving from the second position to the first position and it may simply rotate under
the present weight of the fork and handle bars of the bicycle. In less preferred forms there
may also not be control of rotation when moving from the first position to the second
position.
Exploded diagrams in Figures 9 through 11 show the location of the flexible tensile
member 22 and also the biasing means 24. The hinges 25A and 25B also are shown
disassembled including the hinge pins 33A and 33B. A pivot pin 34 is also shown for the
pulley that forms the bearing point 26. The second axis pivot 27 is also shown – there
may also be a friction reducing interface where the fork mounting portion 5 receives the
fork receiving portion 7 and the second axis pivot 27, for example a bearing surface of
some kind such as a brass, bush or needle and cage bearing or similar.
Shown in Figure 11 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 7 the device 20 acts below the first
axis 6, and in Figure 8 it acts above the first axis 6. In one form as shown in Figures 1
through 7 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 Figures 5 and 8. 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 the preferred form the lock 13 consists of a locking
portion 13A on the fork mounting portion 5 and a locking portion 13B on the first mounting
portion 2. In the form shown in Figures 3 and 8, 13A has a slot 29 and 13B is a lock bolt
captured in the slot 30. When tightened down the lock bolt 30 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
axle receiving portion 42 on the fork receiving portion. The drop out may be a standard
quick release (9 or 10mm in diameter), or may be a through axle such as 10mm, 12mm,
15mm or 20mm 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 17
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
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, or e-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.
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 16 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
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.
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
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
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
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
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.
The foregoing description of the invention includes preferred forms thereof. Modifications
may be made thereto without departing from the scope of the invention.
