Description

Folding cart for purchase.

Object of the invention

The present invention relates to a car Folding for purchase.

Background of the invention

Currently, shopping carts are known constituted by a structure, usually metallic, and that It has a handle and wheels.

In this structure it is mounted attachable or uncoupleably a bag of flexible sheet material provided with a flap as a cover.

Spanish patent 9801958 refers to a car perfected for purchase, of the aforementioned type, in which the structure involves two upper and lower frames related by sloped profiles, in whose lower frame they are fixed frontally two directionally rotating wheels and then two supports vertical blade-shaped swivel with three branches, in whose ends are fixed two wheels, which facilitates the rise of Curbs and stairs.

In this case, and due to the size of the car, necessary on the other hand to get a good capacity, the structure is foldable to be constituted by profiles telescopic tubular lockable in the extended position or deployed

This folding and unfolding system can be easy to handle, especially by people major, inconvenience that is corrected with the car of the invention.

Description of the invention

The car of the invention has a constitution that allows a fast and simple folding, with lightness and versatility.

According to the invention the car is constituted by a structure and a bag, having the structure the front directional wheels and rear supports in the form of blade that facilitate the rise of curbs and stairs.

The improvement proposed by the invention consists in constitute the structure based on two side frames, integral or Detachable, which are related front and back by means of measures that allow folding and volume reduction of the car by approaching both frames in correspondence with the fold or folding of the bag. The compasses they have an interlock or stabilization of their open position that allows to keep the open position of the bag, and consequently of what constitutes the entire car.

The measures are ideally related mechanically with each other, in whole or in groups, in order to simplify the actions that the user has to perform to unfold or fold the car.

Brief description of the drawings

Figure 1 shows a view of the carriage of the invention in deployed position.

Figure 2 shows a view of the structure of the car of the invention.

Figure 3 shows a view of the carriage of the invention in folded position.

Description of a practical embodiment of the invention

The car 1 of the invention is constituted by a lightweight and sturdy metal structure 2, which is foldable and rolling, and to which a bag 3 of sheet material is fixed flexible, preferably equipped with a flap as a cover 4, the bag constituting the receptacle where the objects, such as the constituents of a purchase domestic

The structure has two side frames 5 interrelated by measures 6 front and rear upper and lower. The frames comprise stiffeners 7 stringers diagonals

From the top and back end of each one of the frames emerges a semiase 8, both susceptible to being joined by a folding, telescopic or flexible element 9.

Measures 6 sympathize preferably each other by means of bars 10 that allow their simultaneous closure through a simple action. When closing the bars both frames will approximate generating the volume reduction of the car, as seen in Figure 3 allowing storage, a vacuum, occupying an essentially reduced space.

The bars also have an open position stabilized or interlockable by which the car is deployed and prepared to receive the objects to be transported inside. This position is shown in Figure 2.

To facilitate its mobility, in addition to the handle, the structure of the front carriage in its lower part frontally two Directionally rotating wheels 11, and subsequently supports swivels 12 with angularly equidistant pronunciations, in the end of each of which a wheel 13 is mounted, which It allows you to easily climb stairs and curbs.

Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications of detail as long as they do not alter the principle fundamental.
