## Abstract

A device for securing a vehicle includes a frame member locatable over the upper portion of a tire of a wheel of a vehicle and; a respective tie down attachable to each of opposite sides of the frame member. Each tie down includes an attachment member at its end remote from the frame member, whereby with the frame member located over a tire, the wheel is able to be secured by engaging each connector with an anchor point below the frame member.

## Background
This is a nationalization of PCT/AU2005/000812 filed 7 Jun. 2005 and published in English.
FIELD OF THE INVENTION
This invention provides a device for securing a vehicle in an upright position, for example, during transportation, storage or display.
BACKGROUND OF THE INVENTION
A means of anchoring a motorcycle to a base, for example, of a trailer, display stand or truck, is by using a pair of tie-downs, each in the form of a strap and having a hook provided at each end. Each of the straps may be made of a nylon material of suitable strength and is provided with adjustment means in the form of a buckle or ratchet.
In use, the motorcycle is manoeuvred to locate the tyre of its front wheel on the in a cradle or stand. In some instances, the motorcycle is simply placed onto the base or trailer without use of the stand or cradle. One end of each tie down is hooked at either side of the handlebar or fork. The other end of each tie down is then hooked to an anchor point in the ground or other base for the cradle or stand. The straps are tensioned by adjusting the buckle or ratchet to pull down on the handlebar or fork of the motorcycle, such as to compress the fork about halfway and secure the motorcycle in position. A disadvantage with using such tie downs is that considerable stress is placed on the motorcycle's suspension, resulting in wheel or fork alignment problems, uneven tyre wear or early fork seal failure.
Another arrangement consists of a metal stand or cradle for receiving the front wheel of a motorcycle. The stand or cradle has adjustable side plates between which the tyre of that wheel can be clamped to secure the vehicle. However, such stands need to be fixed or bolted to a floor if used in the transportation of a motorcycle, and require the use of additional safety straps to maintain stability of the motorcycle in transit.
The present invention seeks to provide an alternative form of device.
SUMMARY OF INVENTION
The invention provides a device for securing a vehicle, the device including a frame member locatable over the upper portion of a tyre of a wheel of a vehicle; a respective tie down attachable to each of opposite sides of the frame member; each tie down including a connector or attachment member at its end remote from the frame member, whereby with the frame member located over a tyre, the wheel is able to be secured by engaging each connector with an anchor point below the frame member.
The frame member may have a first portion and a second portion which are disposed relative to each other such that the frame member is substantially symmetrical. Each of those portions may be of U-shape and have an arcuate web which conforms to the curvature of the tyre. Preferably, each U-shaped portion has legs which diverge from its web, with the webs of the first and second portions spaced apart to engage the tyre at circumferentially spaced locations. A connecting member or bracket may be provided between these first and second portions.
The frame member may have at least one elongate load distributing member which is arcuately shaped to conform to the curvature of the tyre. A single load distributing member may extend between the first and second portions of the frame member.

DETAILED DESCRIPTION OF THE DRAWINGS
FIGS. 1 and 3 depict a device 10 according to the invention for securing a vehicle. The securing device 10 has a frame member 20 and tie-downs 50. The tie downs 50 may be attached to the frame member prior to use or may be attached once the frame member is located over the tyre of a wheel. Views of the frame member 20 alone are provided by FIGS. 2 and 4. The frame member 20 is made of a material of suitable strength, such as a metal or a plastics material such as polyvinylchloride.
The frame member 20 has a first portion 22 and a second portion 24 each having a substantially U-shaped configuration. Each of portions 22 and 24 has a pair of legs 30 joined by an arcuate web 28 from which the legs 30 diverge.
The free end of each leg 30 of one of portions 22 and 24 is joined to the free end of a respective leg 30 of the other one of portions 22 and 24 by means of a respective bracket 26. In the arrangement shown, each bracket 26 is of triangular form, and a leg 30 of each portion 22 and 24 extends along a respective side of the bracket 26. Thus, each of portions 22 and 24 is in a respective one of mutually inclined planes. The arrangement is such that, relative to the in-use orientation shown in FIG. 1, frame member 20 is of inverted U-shape as viewed from either end, as shown in FIG. 3, and of V-shape as viewed from either side parallel to the plane of FIG. 3, as is evident from FIGS. 1 and 2.
Each tie down 50 includes an adjustment device 54 at one end, an attachment member 58 at its other end, and a flexible, substantially inextensible strap 52 which interconnects device 54 and member 58. The member 58 is secured to one end of strap 52, while strap 52 is adjustable engaged by device 54. Also, device 54 is adjustable or operable to adjust strap 52 longitudinally for varying the spacing between device 54 and member 58.
Each device 54 is secured to a respective bracket 26 of frame member 20. In each case, this is by means of a bolt 51 which projects from device 54 and engages in an aperture 36 of the respective bracket 26. In the arrangement illustrated, each device 54 is in the form of a ratchet assembly which has a housing 53 from which bolt 51 projects, and a ratchet handle 56 pivotably movable on housing 53 by pin 55. The handle is pivotable to draw the strap 52 longitudinally for reducing the spacing between member 58 and housing 53, while a release mechanism (not visible) enables strap 52 to be pulled in the other direction. The member 58, in the arrangement shown, is in the form of a hook.
FIGS. 5 and 6 depict the securing device 10 in use to secure a motorcycle 60 on a trailer 62 during transit. The front wheel 64 of the motorcycle 60 is located in a wheel guard or brace 68. A first securing device 10 is then located to position its frame member 20 over the upper portion of the back wheel 66 of the motorcycle 60 so that the portions 22 and 24 are substantially symmetrically disposed with respect to the wheel 66. Thus the upper portion of the tyre 61 is received in the space 34 within each arcuate web 28. The hook 58 of each tie down 50 is then hooked to a respective anchoring point in the base 63 of the trailer 62, and the straps 52 are tightened by working the ratchet handle 56 to tension the straps 52 for maintaining the motorcycle 60 securely in place.
The tyres shown in FIGS. 5 and 6 are slicks and have little, if any, tread patterning. Where the tyres are treaded with a cross-groove arrangement, the webs 28 are able to be located within the grooves of the tread pattern for more secure fit.
The base 63 of the trailer 62 shown is in the form of a grating, and each hook 58 is hooked under the grating lattice 65. Where the base is a solid surface, anchoring points, for example each in the form of an eye or hook, can be affixed to the base for receiving hooks 58. The anchoring points may also be located in side walls of a narrow enclosure (not shown) provided the anchoring point is at a height below the frame member 20 when in position on a wheel.
For additional security, a second securing device 10 may be similarly fitted over to the front wheel 64 of the motorcycle 60 as shown in FIG. 5. No other securing means is necessary to secure the motorcycle.
Although the embodiment of FIGS. 1 to 6 has been described with application to motorcycles, the securing device 10 may be used to secure other wheeled vehicles to a base. The same applies to the further embodiments of FIGS. 7 to 21. In each case, the device has a number of applications in transportation, storage or display.
The brackets 26 may be secured to the portions 22 and 24, such as by welding, particularly when the frame member 20 is of metal. Alternatively, particularly where the frame member is of a plastics material, the portions 22 and 24 may be formed integrally with the brackets 26. In either case, the portions need not be joined by brackets 26, but rather they may comprise respective portions of a continuous loop.
In other embodiments, the adjustment device can be of different forms. In one arrangement, it may comprise an adjustment device operable in the manner of the buckle part such as is provided on the fixed loop of a vehicle seat belt. Thus, the strap is able to be manually pulled through that device when securing a vehicle. Also, it will be appreciated, other forms of attachment member can be used, whether this be another form of hook or an alternative releasable attaching means.
In other embodiments, the frame member may comprise a single U shaped portion for location over the upper portion of a tyre so that the U shaped portion is disposed at approximately the 12 o'clock position.
FIGS. 7 to 11 depict a second embodiment of the securing device of the invention. The structure and working of the embodiment generally will be understood by the description directed to the first embodiment. The description of the second embodiment will therefore be limited to principle differences, and to assist with this, the corresponding reference numerals of the second embodiment will be the same as the first embodiment plus 100.
