DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a wheeled hand held carrier of the kind suitable for but not restricted to carrying shopping.
Shopping trolleys in various forms are well known and comprise a metal frame, frequently made to telescope and have a bag attached or designed to support a removable bag. Whilst attempts have been made to reduce the bulk of the frame, this is nevertheless unwieldy and gets in the way of the shopper when using supermarkets. One reason why this is so is that the shopper needs to use an open supermarket trolley within the supermarket which does not readily accommodate the shopping trolley. To overcome this problem specially designed bags have been produced which fit in the supermarket trolley which on completion of shopping can be lifted out and carried to the shopper's vehicle leaving the supermarket trolley behind. This however leaves the shopper with the problem of carrying a large bulky bag in one hand, so that the shopper soon tires of this aid and merely relies on plastic carrier bags provided by the supermarket.
A wheeled hand held carrier according to the present invention comprises a rigid base to which are fixed wheels, the rigid base having an upwardly extending perimeter to which is secured a tubular collapsible upwardly extendable wall at the upper extremity of which is at least one carrying handle, wherein the rigid base is formed as a moulding recessed in two rear positions to receive in each recess a wheel wherein each wheel is mounted on an axle, each axle being snap fitted at each end into a recess in the rigid base. The very simple construction of the carrier according to the invention provides in simple terms a light collapsible wheeled bag which can be easily placed in the supermarket trolley during shopping and then loaded from the trolley after check out when the carrier is folded. The upwardly extending perimeter is advantageous in enclosing and thus tidying the wall and preventing damage to the wall. Furthermore the wall can be formed as an economically manufactured tube which can be sewn or riveted to the perimeter which is preferably in a rectangular form but with generously curved corners. The two wheels are received one in each of two recesses in the rigid base member of the carrier by means of an axle for each wheel snap fitted at each end in the recess. In this arrangement the simplicity of providing a suitably moulded base into which the wheels mounted on short axles can be easily clipped i.e. releasably attached further reduces assembly costs.
The rigid base may be simply formed as a single plastics moulding recessed in two rear positions to receive in each recess a wheel mounted on an axle which during manufacture can be snap fitted into further recesses within the wheel recess. The rigid base and the tubular wall construction provide an economical product which affords the user a simple, strong and good looking carrier. The construction of the base enables the carrier to be waterproof so that it is suitable for use in situations other than shopping for example as a beach bag or for picnics. The upwardly extending perimeter in this case helps to prevent water soaking into the bottom of the carrier.
An embodiment of the invention will now be described with reference to the accompanying drawings in which:
FIG. 1 is a side elevation view of a carrier according to one embodiment of the present invention,
FIG. 2 is a cross section of the base component of the carrier of FIG. 1 taken on lines AA of FIG. 3,
FIG. 3 is an underside view of the base of the carrier of FIG. 1, and
FIG. 4 is a perspective view showing the carrier in a folded condition.
In FIG. 1 of the drawings there is shown a wheeled carrier having a rigid base 2 with a pair of wheels 4 and sewn to the base is a tubular collapsible upwardly extendable wall 6 at the upper extremity of which are two rope handles 8 formed as loops.
The base is in the form of an open box with a flat base 10 from which depend two ramped stand protrusions 12 which enable the carrier to stand upright. Also in the base
