DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to the Figures, there is shown a vehicle recovery device 10 comprising a first track 12 and a second track 13. Each of the tracks 12 and 13 comprises an elongate planar member which may be place adjacent a wheel of a vehicle such that, when the vehicle drives over the tracks 12 and 13, the tracks 12 and 13 provide additional grip.

Each of the first and second tracks 12 and 13 are formed from a plurality of panels 14. Each of the panels 14 comprises a planar member pivotally connected in series with the other panels 14 of the first or second track 12 or 13. The first and second tracks 12 and 13 are therefore moveable between a planar configuration, in which each of the panels 14 within the track 12 or 13 is coplanar, and a folded configuration, in which each of the panels 14 is oriented at an angle to the adjacent panels 14 in the track 12 or 13.

In the embodiment shown, each of the panels 14 is rectangular in shape and each track 12 and 13 comprises a first panel 14a, a second panel 14b and a third panel 14c. The first, second and third panels 14a, 14b and 14c are connected together in series such that, in the planar configuration (as shown in FIG. 6), the tracks 12 and 13 each comprise an elongate planar member being three panels 14 in length and one panel 14 in width. In the folded configuration, each of the panels 14 is oriented perpendicular to each of the adjacent panels 14.

Each of the panels 14 comprises opposed ends 16 and opposed sides 17 (as best seen in FIG. 6). Each of the tracks 12 and 13 is formed by pivotal connections provided between the adjacent ends 16 of the panels 14. That is, the first, second and third panels 14a, 14b and 14c are connected end to end to form elongate rectangular tracks 12 and 13.

When in the folded configuration, the first and second tracks 12 and 13 are connectable together to form a receptacle 11 being a polyhedron shape. In the embodiment shown in which the panels 14 are rectangular, the receptacle 11 is a rectangular prism in shape where the first, second and third walls 14a, 14b and 14c of the first track 12 form a base wall, a first side wall and an upper wall of the receptacle 11 respectively. The first, second and third panels 14a, 14b and 14c of the second track 13 form second, third and fourth side walls of the receptacle 11 respectively.

In the embodiment shown, each of the panels 14 is of the same shape and is square. The resulting receptacle 11 is therefore formed into a cube shape.

The pivotal connection between adjacent panels 14 is provided by hinge barrels 18 provided on each of the ends 16 of panels 14. A first of the ends 16 is provided first hinge barrels 18a and a second of the ends 16 is provided with second hinge barrels 18b. The first hinge barrels 18a are offset from the second hinge barrels 18b such that when the first of the ends 16 of one of the panels 14 is placed adjacent a second of the ends 16 of an adjacent panel 14, the first and second hinge barrels 18 are interleaved. A hinge pin (not shown) may be passed through the interleaved first and second hinge barrels 18a and 18b. In the embodiment shown, the first hinge barrels 18a comprise a pair of hinge barrels and the second hinge barrels 18b comprise three hinge barrels.

A first of the sides 17 of each of the panels 14 is provided also with first hinge barrels 18a and a second of the sides 17 of each of the panels 14 is provided with second hinge barrels 18b. The first and second hinge barrels 18a and 18b engage between the second and first hinge barrels 18b and 18a of the adjacent panels 14 when the tracks 12 and 13 are connected to form the receptacle 11. The hinge barrels 18a and 18b therefore aid in locating the adjacent sides 17 of the panels 14 together in the correct position. Further, the arrangement shown in which each of the panels 14 has first or second hinge barrels 18a and 18b on all sides allows only a single configuration of panel 14 to be produced to create the receptacle 11.

The peripheries of each of the first and second tracks 12 and 13 are connectable in order to form the receptacle 11. A plurality of connectors 22 are provided to connect between adjacent ends and sides 16 and 17 of the panels 14 of the first and second tracks 12 and 13. In the embodiment shown, each of the panels 14 includes a plurality of apertures 24 located adjacent the ends 16 and the sides 17. The connectors 22 are provided to engage into one of the apertures 24 on the first track 12 and an adjacent aperture 24 on the second track 13 to connect the peripheries of the adjacent tracks 12 and 13 together in the shape of the receptacle 11.

Each of the connectors 22 in the embodiment shown comprises first and second plugs 26 and 27 connected by a flexible band 28. Each of the plugs 26 and 27 is shaped to be received in one of the apertures 24 of the panels 14 adjacent an edge thereof.

The plugs 26 and 27 in the embodiment shown comprise tubular protrusions 38 having a rectangular transverse cross section. The apertures 24 are rectangular in shape such that the tubular protrusions 38 engage against inner surfaces of the apertures 24. Walls of the tubular protrusions 38 of each of the plugs 26 and 27 include flexible tabs 31 therein having lugs 30 extending outwardly from the outer wall of the tubular protrusions 38. The lugs 30 engage with the edges of the apertures 24, causing the tabs 31 to flex inwardly. When the tubular protrusions 38 have passed through the apertures 24, the tabs 31 flex outwardly and the lugs 30 thereby engage the panels 14. The bands 28 are flexible such that the bands 28 may bend around the perpendicular connection between an adjacent pair of panels 14.

Each of the panels 14 includes also protrusions 32 on the surfaces thereof. The protrusions 32 provide additional grip between the surface of the tracks 12 and 13 and both the wheels of a vehicle and the ground in use. The panels 14 are also provided with a plurality of holes 34 therein. Further, a plurality of openings 36 are provided. The openings 36 are elongate in shape and located adjacent each of the ends 16 and sides 17 to form handles for lifting the receptacle 11.

In use, the first and second tracks 12 and 13 may be connected together to form a rectangular prism shaped receptacle 11, as shown in FIG. 1. The upper wall of the receptacle 11 may be released by removal of the connectors 22 such that it may be opened to form a lid of the receptacle 11 (as shown in FIG. 8). The vehicle recovery device 10 may therefore be stored within a vehicle in a condition in which it can be used for storage of other items. The receptacle 11 may be secured in place within the vehicle by suitable tie down straps or cables (not shown) which may be passed through the holes 34.

If the vehicle recovery device 10 is required for use in recovery of a vehicle, the connectors 22 may be removed to separate the first and second tracks 12 and 13. The panels 14 of the first and second tracks 12 and 13 are then pivoted such that the tracks 12 and 13 are in the planar configuration and the tracks 12 and 13 may be placed in front of or behind the wheels of the vehicle such that the vehicle may drive along the tracks in a known manner.

The vehicle recovery device 10 therefore provides an effective and useful means for storing the tracks 12 and 13 within the vehicle. As four-wheel drive vehicles will often use receptacles for carrying other equipment, no additional space may be required for storage of the vehicle recovery device 10 when not in use.

It will be readily apparent to persons skilled in the relevant arts that various modifications and improvements may be made to the foregoing embodiments, in addition to those already described, without departing from the basic inventive concepts of the present invention.
