Abstract

Foldable trolley, made with the possibility of loading into and unloading from the vehicle, comprising a frame with support wheels and a container installed inside the frame, characterized in that the container is pivotally connected to the frame, while the frame is rotatable around the axis when folding the trolley, moreover, the trolley is equipped with a support in the form of a rod system, which is pivotally connected to the container and a wheel to reduce friction when the container is rotated.

Description

The trolley is designed to transport goods (purchases) from their location, offers for sale (store shelves) to the buyer's vehicle, for example, a car, then when folded, together with its contents in the buyer's vehicle, for example, in the trunk or in the back of a truck, and transportation from the vehicle to the place of unloading the contents of the cart.

The level of technology.

Analog 1.

From the application for the invention 2010128549/11 published on January 20, 2012, a folding trolley 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, and the structure is made of any material, preferably metal, sufficiently strong and light, and the container is made of any material, for example, metal, plastic or other material, sufficiently suitable for the intended use, similarly light and durable, while the design contains two parallel U-shaped sections that form guides suitable for placement of rollers, n going at 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, soy Inonii with them respective cross members, and wherein the compound is central to the pole rack is provided through polzushku which allows to regulate the desired height using trolleys intended for this series of recesses in the rod, which will fix polzushku in different predetermined positions.

The disadvantages of analogue 1.

In fact, a folding trolley consists of two devices, one of which is a container with support rollers, designed for installation on the other - a folding tubular structure with support wheels, and when folding the latter, the container cannot occupy space inside the tubular structure. According to the application, the loading of the folding trolley into the inside of the vehicle must 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 bottom 2

tubular construction. Either fold and load, or fold and store somewhere. According to the application, there is an advantageous possibility of use with or without a metal structure if, for example, it is envisaged to purchase a large number of goods. What follows from this is difficult to understand. 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 with you (do not load into the vehicle). Or take this design, and not take the container. Thus, the lack of the ability to be folded 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. Analog 2.

The well-known "Trolley built into the trunk of a car" (patent for invention RU 2372236 dated 04/18/2008) selected as analogue 2. This trolley is designed to collect and transport piece packages, mainly when shopping for goods in a supermarket, containing a cargo basket with legs, with wheels of a piano type, The legs are pivotally attached to the load-carrying body of the cargo basket along its longitudinal axis and are folded into the niches of the cargo-basket body, and the trolley is rigidly attached to the load-carrying body of the basket In addition, it has rollers for driving the basket into the car trunk and additionally has a work table movably attached to the carrier body of the basket, on which an electronic unit is located, including a device for reading the barcode of the package being loaded and a microprocessor for generating a barcode list file, the processor being equipped with a port -socket for short-term connection to the cash settlement system of the supermarket to receive a check and cashless payment with an appropriate plastic card.

The disadvantages of analogue 2.

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 protruding inward surfaces (in analogue 2 these surfaces are due to niches) is less convenient for storing any items in it, including goods in the store. The trolley uses piano-type wheels, i.e. small diameter wheels, which is inconvenient for moving such a cart on uneven surfaces. An increase in the diameter of the wheels will require an increase in niches, which accordingly will lead to a decrease in the useful volume of the cargo basket. Extra clips for 3

driving the basket into the trunk of the car is rigidly attached to the supporting body of the basket. This design requires ramps to drive the trolley into the trunk of the car, which complicates the design. Analog 3.

The well-known "Folding basket-transportation for self-service in stores" (US 2196914 Al, ВВВ 3/02, 04/09/1940). The device comprises a folding frame provided with at least three support wheels and removable baskets. The device can be equipped with one or two baskets. The frame contains pivotally interconnected elements, including shelves (racks), which are surfaces intended for installation of the above baskets on them. In this case, you can install baskets on the shelves (racks) of the frame, only if the device is in the unfolded state.

The disadvantages of analog 3.

In fact, a folding basket-carriage, as in the case with analogue 1, consists of several devices, these are two or three devices, one or two of which are baskets, designed for installation on another folding folding tubular structure (frame) with support wheels. When folding the frame, the possibility of occupying baskets of space inside this frame is not provided. Loading a folding basket-transportation in a motor vehicle should be carried out in parts. Baskets, if used as part of a collapsible transport basket, should probably be loaded first. Then you need to do something with the lower tubular structure (with the frame). Either fold and load, or fold and store somewhere. The lack of the ability to be folded together with a basket or baskets in one place in a vehicle is a significant drawback of this folding basket. In addition, the baskets themselves do not have any means of mobility. This means that the user, having brought up a folding - basket transportation to the vehicle, will have to use a sufficiently large muscular force to reload the baskets from the folding frame into the vehicle. Unloading baskets will also be difficult.

As a prototype adopted analog 3.

The problem to which the claimed utility model is directed is to create a cart structure capable of quickly, including with its contents, being loaded into (on) a vehicle and unloaded from the latter.

The technical problem is solved in that the shopping trolley, with the ability to unload and load it into the vehicle, contains a frame (3) and a container (1) mounted on a frame with support wheels (4), while the container is installed inside the frame. The capacity is pivotally connected to the frame, while the frame is rotatable 4

around the axis (2) when folding the trolley. Moreover, the trolley is equipped with a support in the form of a rod system (5), which is pivotally connected to the tank and has a wheel (8) to reduce friction when the tank is rotated.

The technical result achieved by the above set of essential features is to simplify the mechanism of folding the cart.

The mechanism for folding the trolley includes a support in the form of a rod system (5), which allows simple and quick unloading and loading of the trolley into the vehicle by folding it by turning the frame of the trolley around the axis (2) while loading it into the vehicle.

In FIG. 1 shows the trolley in the unfolded state ("capacity on top of the frame"), General view.

In FIG. 2 shows the trolley in the unfolded state (“container on top of the frame”), side view.

In FIG. 3 shows the trolley in the unfolded state (“container on top of the frame”), side view. The rigidity of the trolley is increased.

In FIG. 4 shows the trolley in the unfolded state (“capacity on top of the frame”), an increase in the rigidity of the trolley design.

In FIG. 5 shows a trolley when folded, side view.

Shopping trolley contains a container 1, for example, in the form of a basket (for example, rectangular, which can be made of metal, plastic, wood or other suitable material). The tank 1 is connected to the frame 3 (it is spatial and can be made of metal, plastic, wood or other suitable material) hinged in places 2. The frame 3 is made in such a way that it can rotate outside the tank 1 and can provide support for the tank 1 The possibility of rotational motion of the frame 3 and the possibility of rotational motion of the tank 1 are mutually limited by the designs of the frame and the tank. The frame 3, for example, may have a cross member that prevents the rotational movement of the container 1. In this case, to enable the trolley to be unfolded (“the container is on top of the frame”) and to enable the trolley to be folded between the position for the trolley when unfolded ( "Capacity on top of the frame") and the position of the trolley when folded, the angle of rotation of the frame to the capacity is 180 degrees. The frame 3 is equipped with wheels 4. In order to ensure the loading process of the trolley onto a surface higher than the surface receiving influence from the wheels 4, for example, in the luggage compartment of a vehicle (for example, a car), the trolley is provided with a support in the form of an element 5. Element 5 is a rod system in the form of an H-shaped structure having curved sections 6 (FIG. 4). The element 5 is pivotally, in places 7, connected to the capacity 1. 5

Curved sections 6 are designed to enable the element 5 to be hooked onto the frame 3. Element 5 can be used to increase the rigidity of the entire structure of the trolley in the “container on top of the frame” position. In this case, the element 5 by means of curved sections 6 should be connected to the frame 3. To reduce friction when used as a support, the element 5 is equipped with one or more wheels 8. The tank 1 may have a handle 9 designed to improve the convenience of controlling the cart. Element 10, which, for example, can be a belt, cable, rope, etc., is connected at one end with a frame 3. The other end of element 10 is designed to be impacted by a trolley user.

Use of utility model.

Moving (loading) the trolley to a surface that is higher than the surface receiving an impact from the wheels 4 (supporting) of the trolley. For example, in the luggage compartment of a vehicle. The cart is brought to the vehicle, the element 5 is oriented along the bottom of the tank 1 (basket) (Fig. 2), put on a surface that is higher than the surface receiving the impact from the wheels 4 (on the loading surface). Wheel 8 (if available) facilitates the process of moving with the help of the element 5 of the tank 1 along the surface of the load.
