Description

Title of the invention: OPTIMIZED TROLLEY FOR SHOPPING Technical field

[0001] The present invention relates to the general technical field of manually movable trolleys, of the shopping trolley type, mainly for domestic use.

[0002] The invention relates more particularly to shopping trolleys comprising a metal wire frame and a rolling system. Prior art

[0003] Various types of shopping trolleys are known. Thus, shopping trolleys are known whose rolling system comprises a transverse axle on which is mounted at each end, a wheel or a rotating support with two or three wheels. Such a rotating support is mounted freely in rotation on the axle so as to facilitate the crossing of obstacles or movement on a staircase. These wheels, always unidirectional, generally extend on either side of the chassis and consequently significantly increase the lateral size of the shopping trolley.

[0004] Known trolleys also comprise one or two ground support members allowing said trolley, at rest in a vertical position, to be supported on the ground by means of the wheels on the one hand and at least one support member on the other hand. When the shopping trolley moves with the user, it is tilted so that only the wheels remain in contact with the ground. Moving such a trolley, in a vertical position, can be inconvenient, especially if said shopping trolley is full. Presentation of the invention

[0005] The object of the invention therefore aims to overcome the drawbacks of the prior art by proposing a new, more ergonomic shopping trolley.

[0006] Another object of the invention is to propose a new shopping trolley whose lateral size is reduced.

[0007] Another object of the invention is to propose a new shopping trolley which is simple to manufacture and easy to maintain.

[0008] The objects assigned to the invention are achieved by means of a shopping trolley comprising a rigid frame formed with metal wires and / or tubes, said frame being provided with a high handling handle and a container removably mounted on said frame by means of hooking members, said frame being associated with a rolling system, characterized in that the rolling system comprises four pivoting casters mounted on the frame.

[0009] According to an exemplary embodiment, the chassis comprises a low support base extending into a rising support and stiffening structure, the upper end of which forms the handling handle.

[0010] According to an exemplary embodiment, the swivel casters are independent and are mounted on the underside of the support base.

[0011] According to an exemplary embodiment, the support base comprises at least locally reinforcements, in the form of additional metal wires, to form a rigid mounting support for the swivel casters.

[0012] According to an exemplary embodiment, the frame comprises at least locally metal wires or metal tubes of larger diameter to improve its rigidity.

[0013] According to an exemplary embodiment, the chassis comprises lateral reinforcements connecting the support base to the rising structure.

[0014] According to an exemplary embodiment, the container is a flexible and waterproof bag, provided with hooking members, of the self-gripping strip type, for hanging said container on the chassis.

[0015] According to an exemplary embodiment, the container is a flexible and waterproof bag, provided with attachment members of the strap type for attaching said container to the chassis and allowing said container to be used as a backpack when it is separated from the chassis.

[0016] According to an exemplary embodiment, each swivel castor is assembled by screwing with a metal plate, which is previously fixed on the underside of the support base.

[0017] According to an exemplary embodiment, the metal wires and / or the metal tubes and / or the lateral reinforcements are made of stainless steel.

[0018] According to an exemplary embodiment, the four swivel casters are identical.

[0019] A remarkable advantage of the shopping trolley according to the invention lies in the possibility of moving it very easily when it is in a vertical position. Thanks to the four swivel castors, the shopping trolley can be moved in all directions and pivoted around a vertical axis, even when heavily loaded. It is not necessary to tilt the shopping trolley to move it. This is particularly advantageous when you want to store the full shopping trolley without unloading it.

[0020] Another advantage of the shopping trolley according to the invention results from the possibility of tilting it forwards or backwards to tow or push it. Such tilting lifts two of the four swivel casters and the two swivel casters remaining in contact with the ground ensure the movement of said shopping trolley either by pushing it or by towing it. The handling of such a shopping trolley is thus simplified, in particular during storage operations.

[0021] In addition, the positioning of the swivel casters on the underside of the lower part of the chassis makes it possible to reduce the lateral size of the shopping trolley. Brief description of the drawings

[0022] Other characteristics and advantages of the present invention will appear more clearly on reading the description which follows, given with reference to the appended drawings, given as non-limiting examples, in which:
