Description

The utility model relates to a transport trolley, in particular to a shopping trolley with a folding child seat.

There are three main types of shopping cart technology: metal carts, hybrid carts, and plastic carts. The production technology of a metal trolley is based on bending and welding of a metal rod and pipe, followed by the application of a galvanic or other coating. The least technologically advanced production method available to most manufacturers.

The basket of the hybrid trolley is made of injection molded plastic and is subsequently mounted on a metal frame or chassis equipped with wheels.

The main structural elements of the plastic trolley are made of injection molded plastic and assembled together. In such shopping carts, the use of metal is allowed only in places of special loads.

A transport trolley is known (RU 2705882 C1 "Transport trolley", patent holder WANTSL METALLWARENFABRICK GMBH (DE), published on November 12, 2019). The stackable transport trolley comprises a running gear and a basket. Chassis contains a carrier frame and a wire frame. The wire frame contains a wire frame with two raised basket fastening arches. The basket is put on the basket fastening arcs. A child seat for a stackable transport trolley comprises a backrest to which the seat board is connected with the possibility of movement or rotation.

The disadvantage of this trolley is that it is made wholly or partly of metal, which makes it heavy, prone to deformation from impact and corrosion due to leakage of liquid products or rain if the trolley is left outdoors.

A cart for shopping and advertising was chosen as a prototype (RU 138432 U1 "Cart for shopping and advertising", patent holder Antonenko Rodion Vladimirovich (RU), Nesterov Kirill Borisovich (RU), published on November 10, 1992), the utility model relates to devices for trading equipment intended for the transportation and advertising of goods and services in retail chains. Shopping and advertising trolley, made of plastic, contains a basket, a handle, support legs and wheels. At the same time, the side walls of the basket are made solid without holes and are shifted inside the basket. Panels for placing advertising information are made from advertising layouts covered with a protective film and fixed on the side walls. In addition, the shopping and advertising trolley can be equipped with an electronic tag to use NFC wireless technology.

The disadvantage of the prototype is the lack of ease of control and maneuvering, the wheels are not reinforced and "walk", which makes it difficult to move with a large amount of goods in the basket.

The objective of the utility model is to create a roomy, comfortable, easy-to-handle trolley for goods, with improved maneuverability, stability and strength.

The technical result is to improve the operational properties of the food trolley.

The technical result is achieved as follows.

Shopping trolley with folding child seat, made of plastic, with main push handle, chassis with four wheels, basket. The basket has three additional handles, one of which is located on the opposite side of the trolley from the main push handle, the other two additional handles are located on the sides of the basket, to the left and right of the main push handle. The chassis has a wide mounting area with a basket, the design of all wheel assemblies and attachment points to the chassis are additionally reinforced. Each of the four wheels has two sealed bearings, the bearing installation sites are additionally protected by a protective bearing cap. The folding seat for the child has a seat back which, together with the rear side of the trolley in the upper part, is devoid of protruding parts.

Making the shopping trolley out of plastic makes it possible to reduce its weight to 10 kg, making the trolley lighter by almost one and a half times compared to metal or hybrid trolleys. In addition, there is no problem with corrosion, since polymeric materials are not subject to it, as well as deformations from impacts, plastic "does not remember" the shape from impacts. Thus, the implementation of the trolley of plastic allows you to increase the service life of the trolley and improve its operational properties.

The implementation of the chassis with a wide platform for fastening with a basket allows you to evenly distribute the load over the entire base area, which allows you to increase the strength of the operated shopping cart.

The design of the wheel uses solutions for a soft and quiet trolley ride. In particular, two sealed bearings are used in all four wheels of the bogie, and the bearing installation sites are additionally protected by pads. The structures of all wheel assemblies and the points of attachment to the frame are additionally reinforced. All this allows you to withstand increased loads, while maintaining the smooth running of the shopping trolley.

The design of the basket has additional handles on three sides for easy maneuvering. In addition, the handles allow preschool children to hold on to the sides.

For toddlers, the shopping trolley has a folding child seat, which can also be used as an additional compartment for goods. The child seat has enlarged leg openings to accommodate the child's feet in winter boots. The back of the seat, as well as the rear side of the trolley in the upper part, is devoid of protruding parts to ensure safety during operation. The length of the seat has been increased for greater comfort for children, the length of the seat is 28-30 cm and the width is 13-15 cm. In addition, the longer seat allows you to store small goods or other things that should be at hand in this compartment.
