Detailed description Quad bikes or all-terrain vehicles (ATVs) are increasingly being used as work vehicles in tanning, forestry and other areas. As a result they arc often required lo transport heavy and cumbersome loads. Most of the AT Vs on the market arc not designed lo cany heavy loads, they arc simply viewed as a recreational vehicle or they have trailers or other equipment attached behind them. Canier systems for quad bikes are known, however these carrier sysLems are only suitable tor carrying small loads. These systems do not provide any safety element.

There is a propensity for AT Vs and quad bikes in particular to roll over. Roll over can occur in any direction front, side or rear. It can take place suddenly even at low speeds. If a vehicle rolls· over it can trap and crush the rider leading to serious and even fatal injury. Unfortunately ATVs have a high incidence of accidents.

The ATV is designed to be “driver-active?' On a “driver-active” vehicle like an ATV the operator’s body movements helps control the ATV’s stability··. Driver-active vehicles require a strong combination of skill, good judgment, attention, and physical strength.

It requires skill to maintain an ATVs centre of gravity especially when tlie ATV is being used more as a work vehicle. Safety has been a major issue with ATVs and quad-bikes due to the high number of deaths and injuries associated with them and the negligible protection offered by the machine.

Others have tiled to address the issue of safety jn roll over situations for example the “Quad bar” described irt International Publication No. W02008/028226. While the “Quad bar” docs provide some added protection to the rider, the “Quad bar” does not necessarily offer a lot of protection to tlie rider when the ATV roils onto its side.

The present invention provides a robust protection and carrier system for an ATV which allows a rider to be protected in die event of a back flip as well as a side roil. It also provides an ATV with additional carrying capacity.

The present in vention provides a protection and carrier frame for an ATV which enhances the carrying capacity of’ lhe quad bike and at tire same time provides a safer vehicle as tlie frame prevents a rider from being pinned underneath if rollover of the ATV occurs.

It is important that the protection anti carrier system does not adversely impact the driving of an ATV or quad bike. The load bearing capability of tlie protection anti carrier system of tlie present invention allows tlie user to safely transport heavy and cumbersome loads while at the same time providing protection in the event of the ATV roiling over or back-flipping. The protection and carrier frame is designed to evenly spread the weight of the additional load being carried so that the driving ability of the ATV is not affected. ΰ The protection and carrier frame of. T combined weight of the ATV and carry load. The protection and carrier frame of the invention provides an additional cany weight of up to 120kg.

The protection and carrier frame of the present invention provides a secure mounting base which allows the protection and carrier frame to withstand the weight of the rider, the ATV and an additional weight in the event that tire vehicle turns or rolls over. The rear section of the protection and carrier system of the invention extends above the height of the driver or passenger ofthe ATV and prevents the rider from being trapped underneath tlie ATV in the event of roll over. Side guard arms on the protection and carrier frame prevent a rider from being trapped between the rear section of tlie protection frame and the ATV in the event of a roll-over. The protection and carrier frame of the iii vent ion is capable of withstanding impact and directional force without bending or straining. Tlie protection and carrier frame allows a rider in the event of a roll over to escape safely from under the upturned ATV without being trapped beneath or sustaining the full weight of the ATV.

Fig. 1 shows the protection and carrier frame 1 of the invention. The frame I has a rear section 2 and two side guard sections 3. The rear section 2 has a substantially arched shape and elongated parallel bars 4 extend from the top of the arch to a tow bar on the ATV. Mounting means are detachably attached at the end of tite parallel bars 4. The mounting means comprises a collar plate 5 attached to tlie distal end of the elongated parallel bars 4 which engage with the low bar on the ATV. '['he collar plate 5 is an elongated flat plate. It has a central opening 6 for receiving tbe ball of a tow bar and receiving means 7 on either side ofthe central opening for attachment and securing tlie ends of each ofthe parallel bars 4. The receiving means 7 may be receiving holes as shown in Fig. 5. The ends ofthe parallel bam 4 are inserted into the receiving holes and releasably screwed into position. Alternatively as shown in Figs. 6 and 7 the receiving means 7 may be upright flanges between which the ends of the parallel bars 4 are sandwiched and releasably screwed into position. To attach the protection and carrier Ί frame to a low bar on an A TV or quad bike the ball of the tow bar is removed by unscrewing il from the tow bar, '['he threaded bar is placed through the central opening 6 of the elongate flat plate 5 and the tow bar ball screwed back on.

The protection and carrier frame is also securely attached to the back rack 11 of tire ATV, As shown in Fig. 8. holding bars or hooks 10 on the rear section 2 hook over an outer bar of the back carrier 11 of the ATV securing the protection and carrier structure to the rear carrier. The holding bars are sharply curved bars extending from a lower horizontal baton the real’ section of the I fame which hook over tlie rear carrier of the ATV. Tbe i 0 holding bars 10 arc located towards the outer sides of the rear section.

The mounting means to the tow bar and the attachment means to the back rack of an ATV provide sufficient movement to allow the protection and carrier system to easily move up and down as the suspension of the ATV is compressed.

The two side guard sections 3 extend at right angles to tlie rear section of the frame. The side guard sections 3 extend from either end of the rear section 2, The side guard sections 3 extend along the side of the back rack ΐ I of tbe ATV towards the front of the ATV, The side arms 3 provide means to contain any load being transported by (lie ATV. The side arms 3 also play a safety role in preventing a rider from being trapped between tbe rear section 3 of the frame and the body of the ATV in the event of the ATV rolling over.

The protection and carrier frame may be manti fact Lured from tubular steel or any Other suitable material that is strong and durable. The material needs to be capable of withstanding impact and directional force without bending or straining. It is a simple yet robust structure able to sLipport heavy loads and/or the weight ofa upturned ATV. it has lo be a robust structure yet not too cumbersome so as to interfere with Lhe driving experience.

The protection and carrier frame of the invention is manufactured as a unitary piece. The frame comprises a single piece. The holding bars may be an integral part of the rear section of the frame. The unitary structure provides a strong and durable structure. It also means it is very simple to attach to an ATV. The frame may be hooked onto the rear carrier of an ATV and then the detachable mounting means simply attached to tlie tow bar.

The vertical section comprises a pair of parallel tubular bars 20, AI tlie upper end the bars 20 arc bent together. The bars may be bent together forming a substantially square arch shape. The parallel bars 20 may be bent together forming any other suitable shape. The lower end the parallel bars 20 are attached to an elongate flat plate 21. The flat plate 21 comprises three openings, a central opening 22 and two outer openings 23, To attach the carrier system to a tow bar on an ATV or quad bike the ball 24 of the tow bar is removed by unscrewing it from the tow bar. The threaded bar is placed through the central opening 22 of the elongate flat plate 21 and the tow bar ball screwed back on. Two screws thread 2(1 through cither outer opening 23 anti thread through the end of each of the parallel bars 20.

The protection and carrier system of the invention is detachably mounted to the rear of an ATV at a ninety degree angle, The ends of tlie parallel bars 2(.) curve at a ninely degree angle lo the flat plate 21. The parallel bars 20 extend vertically and the vertical section of the carrier system extends higher tlian the drivers head.

Thc horizontal section has a pair of parallel tubular bars 25 which run substantially parallel to the back rack 11 of an ATV or quad bike 35. The parallel lobular bars 25 run along the length of the back rack 11 and bend at an angle to follow the sides of the back rack 11, At either end the parallel bars 25 are bent together forming a square arch.

Reinforcing siruls may be added between the parallel bars to provide additional strength to the protection and carrier system Fig. 12 shows one embodiment of the invention where the protection and carrier system 5 is attached Lo the back rack IS by means of straps 30. Fig. 13 shows another embodiment of the invemion where lhc protection and carrier system interlocks with tlie back rack 11 of an ATV. In this instance the conventional back rack 1 1 of an ATV may be simply and easily replaced with an altered back rack incorporating a holding bar 31. t he vertical parallel bars 20 of the protection and carrier system 1 are inserted down Lhrough the holding bar 31 of the back rack 11 and the ends of the bars 20 attached as described before to the elongate flat plate 21. Fig. 15 shows a further embodiment of the invention where hooks 33 on the horizontal section simply hook over and engage with an outer bar on the back rack. 11 of the ATV. ] 5 The mounting means to the tow bar and the attachment means to the back rack of an ATV provide sufficient movement to allow the protection and carrier system to easily move up and down as the suspension of the ATV is compressed.
