A shopping trolley, which includes a holder for holding articles of shopping, and a wheeled undercarriage connected to the holder. The undercarriage is operable between an erected condition, in which the undercarriage supports the holder at a working height above the ground on wheels, and a collapsed compact condition, for loading of the trolley into a boot of a passenger sedan so that the holder provides a boot organizer. In one embodiment of the invention, the undercarriage comprises a pair of telescopically extendable curved legs, which have wheels mounted thereon. A vehicle, which has a securing arrangement in its boot specifically for securing the collapsible shopping trolley in a stable condition in the boot, when the undercarriage of the trolley is collapsed.

The invention claimed is: 1. A shopping trolley, comprising: a holder for holding articles of shopping; and a wheeled undercarriage connected to the holder, the undercarriage being operable between an erected condition, in which the undercarriage supports the holder at a working height above the ground on wheels, and a collapsed compact condition, for loading of the trolley into a boot of a passenger sedan, the undercarriage comprising a pair of elongate curved legs, each leg being part-circular in shape and slidably mounted on an associated frame member also having a part-circular shape corresponding to the shape of the leg, to permit telescopic sliding of the legs in a circumferential direction between an extended position in which each leg projects from its associated frame member for engagement of the wheels with the ground, and a retracted position in which each leg is located within its associated frame member. 2. The shopping trolley as claimed in claim 1, which is supportable on a floor of a vehicle boot, when the undercarriage is in its collapsed condition, such that the holder has an orientation relative to the vertical similar to the orientation of the holder when the undercarriage is in its extended condition and supports the holder on the ground, so that the holder provides a boot organizer. 3. The shopping trolley as claimed in claim 2, wherein spacing of the holder from the ground surface, when the undercarriage is in its erected condition, is such that the holder is accessible to a person of average height in normal stance, the spacing being greater than 0.45 m. 4. The shopping trolley as claimed in claim 1, wherein the holder defines a storage space which is divided into a number of compartments. 5. The shopping trolley as claimed in claim 1, wherein the undercarriage has a set of four wheels which are arranged in a rectangular configuration in plan view, when the undercarriage is in its erected condition, each roller being freely swivelable about an associated upright swivel axis. 6. The shopping trolley as claimed in claim 1, wherein each leg has mounted thereon a displaceable handle such that, when the leg is in its extended position, the associated handle is located adjacent a rear of the trolley, in its fore-and-aft direction, for gripping by a user, each handle being pivotally displaceable relative to the associated frame member about a pivot axis which extends transversely to the fore-and-aft direction of the trolley in its erected condition, so that, when the leg is in its retracted position, the handle is pivotally displaceable about its pivot axis towards the associated frame member to lie adjacent the frame member. 7. The shopping trolley as claimed in claim 1, wherein each leg has mounted thereon a pair of wheels spaced along the length of the leg, each wheel being spaced from the associated leg by an elongate foot which is pivotally connected at one end thereof to the leg for pivotal displacement about a pivot axis which extends transversely to the fore-and-aft direction of the shopping trolley, an associated wheel being provided at the opposite end of the foot, each foot being pivotally displaceable between a stowed position in which it lies adjacent the associated leg, and an operative position in which it projects transversely from the associated leg, so that the associated wheel is spaced from said leg by the length of the foot for engagement with the ground. 8. The shopping trolley as claimed in claim 1, wherein each part-circular leg and its associated part-circular frame member, in the erected condition of the undercarriage, lie in a more or less vertical plane and define a gap between their ends at a front of the trolley in the fore-and-aft direction of the shopping trolley, said gap being sufficiently large to straddle a rear portion of an open boot of a passenger sedan when the shopping trolley is wheeled towards the boot of the vehicle, in use, so that part of the legs is receivable in a space between the ground and the rear of the vehicle, the frame members engaging the rear of the vehicle, to rest thereon. 9. The shopping trolley as claimed in claim 1, comprising an auxiliary holder for holding articles of shopping, the auxiliary holder being removably and replaceably connectable to the legs to extend between the legs when they are in their extended positions, the auxiliary holder additionally serving as a strengthening cross-member between the legs to enhance lateral stability of the undercarriage. 10. The shopping trolley as claimed in claim 1, comprising a pair of auxiliary wheels which are respectively mounted on the frame members adjacent ends of the frame members in the fore-and-aft direction of the trolley, such that the auxiliary wheels are engageable with the ground when the extendable legs are in their retracted positions and an end of the trolley opposite the auxiliary wheels is gripped by a user, to permit wheelbarrow-fashion operation of the trolley. 11. A vehicle assembly, comprising: a shopping trolley as claimed in claim 1; and a vehicle which includes a body defining a boot, the boot having a securing arrangement specifically for securing the shopping trolley in a stable condition in the boot during normal operation of the vehicle, the shopping trolley being supported with its undercarriage in its collapsed condition on a floor of the boot of the vehicle and being secured in a stable condition by the securing arrangement provided by the vehicle. 12. The shopping trolley as claimed in claim 3, wherein the spacing of the holder from the ground surface, when the undercarriage is in its erected condition, is 0.5-0.6 m. 13. The shopping trolley as claimed in claim 4, comprising a number of durable shopping bags which are receivable in a storage space of the holder, the bags forming a permanent part of accessory, being removable from the holder and being intended for repeated use. 14. The shopping trolley as claimed in claim 13, wherein the bags are of a woven flexible textile material. 15. The shopping trolley as claimed in claim 13, wherein at least some of the bags are insulated to provide thermally insulated storage chambers. 16. The shopping trolley as claimed in claim 13, wherein at least one of the bags has a closure mechanism for openably closing the bags. 17. A shopping trolley, comprising: a holder for holding articles of shopping; and a wheeled undercarriage connected to the holder, the undercarriage being operable between an erected condition, in which the undercarriage supports the holder at a working height above the ground on wheels, and a collapsed compact condition, for loading of the trolley into a boot of a passenger sedan, the undercarriage comprising a pair of elongate curved legs, each leg being part-circular in shape and slidably mounted on an associated frame member between an extended position in which each leg is arranged end-to-end with its associated frame member for engagement of the wheels of that leg with the ground, and a retracted position in which each leg is retracted relative to its associated frame member, wherein the pair of frame members are displaceable relative to each other between an operative condition in which the frame members lie in parallel planes which are laterally spaced apart in a direction transverse to the fore-and-aft direction of the shopping trolley a sufficient distance to permit temporary storage of articles of shopping in a space defined between the frame members, and a fully collapsed condition in which the frame members lie more or less flat against each other.
