DETAILED DESCRIPTION
Figures 1 and 2 show a preferred embodiment of a ramp assembly 1 for a vehicle 2.
References to vehicle 2 throughout the specification relate to any type of vehicle 2 which
has a cargo tray (or truck tray) 3 or flatbed at the rear of it i.e. a utility vehicle or pickup
truck. It will also be appreciated by those skilled in the art that the assembly 1 can be
used on trailers.
The assembly 1 has a support 4 which is mounted to the side walls of a cargo tray 3 (or
a trailer) by bolts or the like. The support 4 is shaped like a bridge and has two legs at
each side of the tray 3 and a horizontal elongate member joining the legs. As can be
seen the legs have angled wings 5 which enhance strength and rigidity to the support 4
when it is used as an anchoring point when loading and unloading wheeled vehicles and
machines (e.g. ATV vehicles, four wheeled vehicles, tractors, lawnmowers or
motorcycles etc). The support 4 also has a cross bar 6 which helps protects the cab
when a wheeled vehicle is loaded. The support 4 is preferably made from one piece
however those skilled in the art will appreciate that it can be made from one than one
part. In addition the support 4 is preferably made from folded welded metal construction
although other suitable materials can be used.
When in the travelling configuration like shown in figures 1 and 2 located on top of the
support 4 are two removable ramps 7, 8 which are plank like in shape and have at least
two side walls and at least two end walls. The ramps 7, 8 can be attached or fastened
to the support 4 by removable pins or the like however in some embodiments they need
not be attached as they are shaped such that they releasably engage with the support 4
(e.g. by nesting over it). As shown the ramps 7, 8 are adapted such that they can be
stacked both over the support 4 and one ramp 8 over the top of the other ramp 7. The
ramps 7, 8 may be deployed singly or dually to bridge obstacles and provide traction
(e.g. on steep banks, in slushy conditions etc) like that shown in figure 3. The ramps 7,
8 are preferably made from metal and preferably have turret punched (e.g. flanged)
holes with their flanged side uppermost. The ramps 7, 8 also preferably have a profile of
folds to provide strength and guiding barriers on their edges to keep wheeled vehicles
and the vehicle 2 on track when in use. In some embodiments the ramps 7, 8 can have
traction enhancing treads. The advantages of storing the ramps 7, 8 on top of the support
4 is that they do not take up room in the cargo tray 3 and are convenient to access. This
is advantageous over other methods of storing ramps that may require extra attachment
devices for storing the ramps in the cargo tray 3 during transport.
As shown in figure 4 the assembly 1 optionally has a ramp bar 9 which is fitted to the
tailgate 10 of the vehicle 2. This provides a mounted structure to support the ramps 7, 8
when they are used to load wheeled vehicles onto the cargo tray 3. The ramps 7, 8 are
preferably adapted such that they can releasably engage (e.g. clip on and off) with the
bar 9. The bar 9 is preferably made from welded metal and is permanently attached to
the tailgate although in some embodiments the bar 9 can be made from other suitable
materials and can be removable.
The assembly 1 also optionally has a removable remote controlled electric winch 11
mounted (e.g. with quick release keyhole and pins or the like) to the support 4 like shown
in figure 5. This winch 11 is attached to a wheeled vehicle when in use such that the
wheeled vehicle can be loaded and unloaded unmanned. Alternatively, or in addition to
an electric winch 11 the assembly 1 can also have a removable self retracting safety line
12 illustrated in figure 6 in which on end attaches to the support 2 (e.g. clips onto an
aperture in the centre of the support 4) and the other clips to the front of a wheeled
vehicle. The safety line 12 helps prevent the attached vehicle tipping over backwards
during manned loading or unloading. Any suitable safety line 12 could be used e.g.
climbing or industrial safety lines.
Figure 7 shows an ATV 13 being loaded onto the cargo tray 3 of a vehicle 2. As can be
seen the ramps 7, 8 have been attached to the bar 9 and the safety line 12 has been
attached to the ATV 13. Figure 8 shows the ATV 13 once loaded on the cargo tray 3.
The loaded ATV’s 13 rear wheels 14 are raised using a jack 15 allowing the ramp(s) 7,
8 to be placed against the front wheel 16 of ATV 13 like can be seen in figure 9. The jack
15 is then lowered placing the rear wheels on the ramps 7, 8. This spreads the load of
the ATV 13 onto the ramps 7, 8 and away from the tailgate hinges and support cables.
The tailgate is left down for transport and the ATV 13 is secured by tie downs or the like.
The jack 15 is used again to raise the rear of the ATV 13 for unloading. However, in
some embodiments (e.g. a single cab or extra cab vehicle) the cargo tray may be of
sufficient length to allow the tailgate to close when an ATV 13 is loaded. In these
embodiments there is no need to position the ramps 7, 8 under the ATM 13 to support
the tail gate and the ramps 7, 8 can be stored as normal for travel.
In some embodiments the assembly 1 has a solar shower 17 like shown in figure 10.
The shower 17 comprises a solar shower water bag 18 and an adjustable hooked pole
19. One end of the pole releasably engages with the support 4 and the ramps 7, 8 (e.g.
via angled apertures in them). It will be appreciated that other type of connections
between the shower 17 and the support 4 and ramps 7, 8 are possible. In some
embodiments the assembly can have more than one shower 17. When not in use the
shower bags 18 nest transversely inside the top ramp 8 such that they receive the
maximum amount of sun and are isolated from damage from items in the cargo tray.
In use if a user decides that he needs to enhance the traction of the wheels of his vehicle
2 (e.g. in sand, snow, mud or one a steep bank) or to bridge an obstacle such as a
stream or uneven terrain he will get out of his vehicle 2 and remove the ramps 7, 8 from
the support 4 and place them on the desired location on the ground in front or under the
wheels and then use the ramps 7, 8 for traction or to bridge the obstacle in his vehicle 2
and once this has been done he can put the ramps 7, 8 back on top of the support 4.
When loading a wheeled vehicle such an ATV 13 a user attaches the winch 11 or safety
line 12 if they are not already attached to the support 4 and opens the tail gate and
attaches the ramps 7, 8 to the rail bar 9. The user then attaches the winch 11 or safety
line 12 to the ATV 13 and loads the ATV 13 onto the cargo tray 3 (the ATV 13 can be
loaded unmanned if winch is used). Once loaded the rear of the ATV 13 is jacked up so
that the ramps 7, 8 can be removed from the bar and placed under the back wheels of
the ATV 13 such that they abut against the front wheel of the ATV 13. The tailgate is left
down for transport and the ATV 13 is secured by tie downs or the like. To remove the
ATV 13 the process is reversed.
The previously described system and method of loading and unloading and ATV onto a
cargo tray provides a much safer and more effective way than known ways of loading
and unloading ATVs onto cargo trays.
If the user wishes to have a shower 17 he would attach one end of the adjustable hooked
pole 19 to the solar bag 18 and then insert the other end into the angled apertures into
the ramps 7, 8 and support 4 such that the shower 17 is above the vehicle out of the
users way and can maximise the warmth from the sun.
Figures 11 and 12 show an alterative embodiment of a support 20. The legs 21 of the
support extend down into a cargo tray and against the inner side walls of the cargo tray
when in use. The support 20 is attached to the floor of a tray/deck with bolts 22 or the
like such that the support 20 can be easily removed. Another reason for the legs 21 and
support 20 described in this embodiment and previous embodiments attaching to the
floor is so the sides of the deck can be lowered.
Figures 13 and 14 also show an alternative embodiment of a support 23 which can be
used for a flatbed ute. This support 23 is fixed to a vehicle by welding to the headboard
24. It can be added to an existing headboard or configured into a new build. The support
23 can also have an angled leg 25 bolted to a tray/deck. The ramps as previously
described hook onto a bar 26 on the tailgate. Preferably chains or wire rope etc (not
shown) are used to secure the tailgate into a horizontal position to allow for loading and
unloading of ATV etc.
It will be appreciated that the various parts of the assembly 1 can be produced in a range
of different sizes. It will also be appreciated that the assembly 1 can be made in a number
of different ways and can be made from a number of different materials.
It is to be understood that even though numerous characteristics and advantages of the
various embodiments of the present invention have been set forth in the foregoing
description, together with details of the structure and functioning of various embodiments
of the invention, this disclosure is illustrative only, and changes may be made in detail
so long as the functioning of the invention is not adversely affected. For example the
particular elements of the support 4, 20, 23, the ramps 7, 8, the rail bar 9, the winch 11,
the safety line 12 and the shower 17 may vary dependent on the particular application
for which it is used without variation in the spirit and scope of the present invention. In
addition, although the preferred embodiments described herein are directed to a ramp
assembly for a vehicle it will be appreciated by those skilled in the art that variations and
modifications can be made within the scope of the appended claims.
