BAC K G ROU ND O F T H E INV E NT ION

Shopping trolleys and shopping baskets are used as carrying device during shopping and materials such as shopping bags, sacks, nets are used in order to carry these products after the shopping. Shopping baskets used during shopping do not provide an ergonomic structure for the user because of their fixed forms. Also, due to the fact that they have a self-weight, they impose an extra burden apart from the product put into the basket by the user to purchase. In addition to these, the fact that the baskets cannot be cleaned during their utilization by different users causes them to be unhygienic in case of pouring of fluid products. A nother disadvantage of the embodi merits i n the state of the art is that they cannot enable to categorize the purchased products during shopping. Shopping carriage devices do not have fixed forms and an undefined area, which is narrow and wherein it is difficult to place the product, occurs when their mouth parts are opened. The fact that one hand of the user is full with the product that s/has taken from the section and the other one is full with the current carriage device makes it quite difficult to scan the product to the carriage device and place it. In this case, the carriage device is put down and it ^' s mouth is opened on the ground. When the product is placed, the carriage device is picked up again and the shopping continues. This process goes on for every product purchase and it becomes more difficult as the bag weight increases. Although the time lost at every product purchase seems short, it becomes evident that the loss of time is unacceptably long when a calculation is made by considering the number of products per person. On the other hand, the process is quite difficult and non- ergonomic for the user.

The prior art and the documents described below are compared in the research conducted.

In this detailed description, the inventive interface (1) is described by means of examples, which will not compose any limiting, only in order that the subject matter is understood better.

With the purpose of ensuring that the subject matter of the invention is understood better, a structure which is in the form of a bag with at least two apertures for carriage is mentioned as carrying device in the description. The subject matter of the invention relates to an interface (1) for keeping the carrying device open during shopping. Isometric view of the invention is given in the Figure 1 and top view of the invention is given in the Figure 2. The subject matter of the invention is an interface (1) for carrying a carrying device such that its mouth is open; it distinctively comprises:

- a body (10) which is provided with an opening (11) and can keep the mouth of the carrying device open; and

- at least two hanger units (20) which have a form whereby the carrying devi ce can be i ntegrated.

The said body (10) consists of an opening (11) which enables product pass and a surface which frames this opening (11). The opening (11) is any aperture which is shaped in a size wherefrom at least the products to be placed to the carrying device can pass. The main objective of the body (10) is to keep the mouth part open by bringing it to a fixed form when the said carrying device is hanged to the hanger unit (20). The hanger unit (20) may be any structure wherein the said carrying device can be hanged and which will prevent the carrying device from si i di ng over the i nterf ace ( 1 ) duri ng the carri age.

A preferred embodiment of the invention comprises a handle (30). The handle (30) is connected onto the body (10).

The said interface (1 ) can be one-piece and it can preferably be composed by connecting the body (10), the hanger unit (20) and the handle (30) ^" which are formed separately ^" with each other. A similar embodiment is shown in the Figures 3 and 4. The interface (1), the body (10), the hanger unit (20) and the handle (30) are composed in one-piece and the hanger unit (20) is positioned on the handle (30). The hanger unit (20) can alternatively be positioned on the body (10).

In another preferred embodiment of the invention, the said body (10) consists of plates (101) which are connected to each other only by means of the handle (30) and each plate (101 ) comprises at least one of the said hanger units (20). The plates (101) similarly enable to open the mouth part of the carrying device hanged to the interface (1) by means of the hanger unit (20). The plates (101) act as an opening (11 ) here. This embodiment can be seen in the Figure 5. The said plates (101) provides the same technical benefit with a lighter structure here as an alternative of the body (10). All embodiments described for the body (10) can also be appl i ed for the pi ates (101).

In another preferred embodiment of the invention, the said body (10) has an inclined form. The inclination at a certain radius created here prevents tears by reducing the pressure that the carrying device ^" the mouth part of which is opened by the sai d plates ( 101 ) or the body ( 10) ^" wi 11 undergo at the parts on the edges of the body (10) and the plate (101).

In another preferred embodiment of the invention, the end parts of the said plates (101) are rounded. This prevents tears by reducing the pressure that the carrying device ^" the mouth part of which is opened by the said plates (101) ^" will undergo at the parts on the edges of the pi ate ( 101 ) .

In a preferred embodiment of the invention, the hanger unit (20) is a moving structure and comprises a spring (21) mechanism which enables the said hanger unit (20) to show a closing tendency. The said closing tendency enables the hanger unit (20) to switch to a closed position and compress the carrying device. No tension occurs on the spring (21) while the hanger unit (20) is in a closed position, however, the force applied to the hanger unit (20) for switching to an open position creates a tension on the spring (21). The said tension causes the hanger unit (20) to show tendency for switching to a closed position again. The said structure can be seen in the Figure 6. The spring (21) preferably has torsion type. One leg of the spring (21) is fixed on the interface (1) and the other end thereof is placed to a slot created inside the hanger unit (20) such that it will be connected with the hanger unit (20). The hanger unit (20) is closed in the said first spring (21) position. When the hanger unit (20) is moved towards the open position, the end of the spring (21 ) connected to the hanger unit (20) moves together with the hanger unit (20) and the motion creates a torsion force on the spring (21). The torsion force closes the hanger unit (20) by pulling the spring (21) towards the first position when the hanger unit (20) is released.

A preferred embodiment of the invention comprises at least one carrying unit which enables to integrate the full carrying devices to the interface (1). Thereby, the user can hang a second carrying device to the hanger units (20) by hanging the full carrying device to the hanger unit (20).

The body (10) can comprise at least one mounting member for enabling to place the interface (1) to another means. The said means can be any of drivable means such as a shopping trolley. The said integration member can preferably be a hook and can also be selected among structures having clip, lock or screw alternatively. In an alternative embodiment, the invention can be contained so as to be easily received from inside a dispenser in order to provide the carrying device.

The protection scope of the present invention is stated in the claims provided enclosed herewith and it cannot be definitely limited to the aforementioned in order to for the purpose of illustration in this detailed description. Because it is apparent that a skilled person in the art can present similar embodiments in the I i ght of the af orementi oned.
