Description

The utility model relates to manual means of transportation and can be used to transport goods (purchases) from their location, offers for sale (store shelves) to a buyer's vehicle, such as a car, then when folded, together with its contents in the vehicle the buyer, for example in the trunk or in the back, and transportation from the vehicle to the place of unloading the contents of the cart.

From the application for the invention 2010128549/11, publ. 01/20/2012, a folding cart is known for transporting purchases from a store to a car and from a car to a house. The trolley contains a lower tubular structure on which the container is mounted, the structure being made of any material, preferably metal, sufficiently strong and lightweight, and the container is made of any material, for example metal, plastic or other material that is sufficiently suitable for intended use, similarly light and durable, while the design contains two parallel U-shaped sections that form guides suitable for placement of rollers, tries located on the bottom of the container, the guide rods have corresponding swivel joints at the ends that connect them to both side racks equipped with the corresponding wheels in the lower part, and together with the third middle strut, pivotally connected to the side racks using the section provided in its center , with a wheel at its lower end, form a folding base of the trolley, the upper part of the central rack is connected to a longitudinal rod located between the guide rods and, in turn, is connected connected with them by the corresponding cross members, and the fact that the connection of the central rack with the rod is made through a cushion, which allows you to adjust the required height of the trolley with the help of a series of recesses in the bar, which will fix the creep in various predetermined positions.

A disadvantage of the known trolley is that in fact a folding trolley is two devices, one of which is a container with support rollers, designed to be mounted on the other - a folding tubular structure with support wheels, and when folding the latter, it is not possible for the container to occupy the space inside the tubular structure. Loading a folding trolley into the interior of the vehicle should be carried out in parts. The container, if used as part of a folding trolley, should probably be loaded first. Then you need to do something with the lower tubular structure. Either fold and load, or fold and store somewhere. There is a predominant possibility of use with or without a metal structure if, for example, it is envisaged to purchase a large number of goods. Probably, in the latter case, the metal structure (lower tubular structure) will not fit into the vehicle. That is, this metal structure should in any case not be taken along (not loaded into the vehicle), or this structure should be taken, and not taken the container. Thus, the absence of the possibility in the folded state together with the container to occupy one place in the vehicle is a significant drawback of this folding trolley. The design of the container with support rollers does not provide a means of ensuring a decrease in the mobility of the container in (on) the vehicle. Unplanned movement of cargo in (on) a vehicle is undesirable.

Closest to the proposed one is a trolley built into the trunk of a car (patent for invention RU 2372236 dated 04/18/2008), which is designed to collect and transport unit packages, mainly when shopping for goods in a supermarket, containing a cargo basket with legs, with wheels piano type. Two shafts are attached to the bearing body of the carriage in sliding bearings, on the protruding ends of which the right and left control levers and short levers connected to the spring shock absorber are respectively fastened to the right and left. The diagonally arranged legs are rigidly fixed to the respective shafts, and another diagonally arranged pair of legs sits on the shafts articulated on the sliding bushes. Each pair of legs on one side of the supporting body is connected using rods pivotally connecting the legs and a short lever on one side. The legs by means of rods are folded into the niches of the body of the cargo basket, and the trolley has additional rollers rigidly attached to the supporting body of the basket to drive the basket into the trunk of the car.

The disadvantage of the trolley is a complex mechanism for folding the legs, including levers, shafts, sliding bushings and traction. In addition, the body of the cargo basket has niches designed for folding legs. These niches are made by reducing the internal volume (capacity) of the cargo basket. A cargo basket with surfaces protruding inward is less convenient for storing any items in it, including goods in a store. Additional rollers for driving the basket into the trunk of the car are rigidly attached to the carrying case of the basket. This design requires ramps to drive the trolley into the trunk of the car, which complicates the design.

The problem to which the claimed utility model is directed is to create a simple trolley design that is convenient for storing items in it and does not require special ramps for loading it into the car trunk.

The technical problem is solved in that in a folding trolley containing a container mounted on a base having legs with wheels, the container is pivotally connected to the base with the ability to rotate the base around an axis passing along the edge of the bottom of the container, so that at least when folded one leg of the base is located on the outside of each of the two opposite walls of the tank, and the tank has downwardly facing support projections from the side opposite to the hinge connection with the base.

In addition, to reduce friction when loading the trolley into the vehicle and when unloading it, at least one supporting protrusion has a wheel at the end.

The technical result achieved by the utility model is to eliminate the need to use additional devices (ramps) to load it into the trunk of the car due to the direct interaction of the protrusions with the trunk of the car.

In addition, the proposed trolley has a simpler design by reducing the number of elements of the folding mechanism, and also has a larger usable volume due to the fact that the folded legs are placed outside the container.

In FIG. 1 shows a trolley when unfolded, general view.

In FIG. 2 shows a trolley when folded, side view.

The folding trolley contains a container 1, for example, in the form of a basket, which can be made of metal, plastic, wood or other suitable material. The tank 1 is pivotally connected in places 2 to the base 3, which is a rod structure having a cross member 4, on which the tank 1 rests, and the legs 5 with wheels 6. The base 3 can be made of metal, plastic, wood or other suitable material. The base 3 is made in such a way that the distance between the legs 5, located on opposite sides of the container 1, is greater than the width of the container, so that when the base 3 is rotated around the axis of the hinges 2, at least one leg on each side is located outside the container 3. Possibility the rotational movement of the base 3 and the possibility of rotational movement of the tank 1 are mutually limited by the designs of the base 3 and the tank 1. The base 3, for example, may have a cross member that impedes the possibility of rotational movement of the tank 1. to provide the possibility of bringing the trolley in the unfolded state ("capacity on top of the base") and to enable the trolley in the folded state between the position for the trolley in the unfolded state ("capacity on top of the frame") and the position of the trolley in the folded state, the angle of rotation of the base 3 relative to the tank 1 is approximately 180 degrees. The tank 1 may have a handle 7, designed to improve the convenience of controlling the trolley.

In order to ensure the loading process of the trolley onto a surface higher than the surface on which the wheels 6 are located, for example into the luggage compartment of a vehicle (for example, a car), the trolley is provided with at least two supporting projections 8. The protrusions 8 are directed downward and are preferably made on the lower part (bottom) of the tank in the place of its adjacency to the side walls and the front wall of the tank 1, opposite the back wall of the tank 1, from the side of which there are places 2 of the hinged connection of the tank 1 with the base 3.

To reduce friction when used as a support, at least one of the protrusions 8 is provided with a wheel 9.

The trolley is used as follows.

When loading the trolley onto a surface that is higher than the surface receiving influence from the wheels 6, for example, into the luggage compartment of the vehicle, the trolley is brought to the vehicle, press the handle 7 so that the front part of the trolley lifts, support projections 8 on the loading surface . At the same time, the base 3 is rotated relative to the container 1 until it is rotated 180 degrees, the folded cart is supported with one protrusion 8, and thus the cart is brought onto the loading surface. The wheel 9 on at least one support protrusion 8 (if any) facilitates the process of moving the cart along the loading surface. The presence of wheels 9 allows you to use both one and the other support ledge 8 when you turn the cart when loading in any direction. When unloading the trolley, all actions are performed in the reverse order: they turn the folded trolley on one of the support projections 8, rotate the base 3 180 degrees to support the tank 1 on the cross member 4 of the base, lower the trolley to the support on two wheels 6, remove the support protrusions 8 from the surface loading and lowering the trolley to all wheel support 6.

The presence of support projections 6 and a simple folding mechanism of the cart allow unloading and loading of the cart into the vehicle simply and quickly by folding it by turning the base 3 of the cart around axis 2 while loading it into the vehicle without the use of additional devices (ramps).
