1 is a perspective view illustrating an extension bag according to an embodiment of the present invention. Hereinafter, the description will be made with reference to FIG. 1, and the components not shown in FIG. 1 are referred to as separate reference drawings.

The expansion bag according to one aspect of the present invention comprises a bag 10, a zipper 20, an inner skin 30, and a zipper handle 40.

In one aspect of the present invention, the bag 10 is provided so as to be able to contain an object. The bag 10 may have a bag strap 5 capable of supporting the bag 10, and various types of bags 10 may be used. The bag straps 5 may be provided in diagonal directions facing each other. This is because if the bag strap 5 is located on the same plane or on the opposite side of the bag, the bag can be tilted because the center of gravity of the bag does not match, but if the bag is arranged diagonally facing each other, The bag 10 can be prevented from tilting. Further, the bag strap 5 can be fastened to the bag using a separate hook. The bag 10 may be provided in the form of a backpack, a shoulder bag, a cross bag, or the like.

1 to 3, a zipper 20 is provided on both side edges of the bag 10 in pairs. The zipper (20) makes it possible to extend to both sides of the bag (10). When the zipper 20 is moved to the upper end of the bag 10, the zipper 20 is locked and used as a general bag 10. When the zipper 20 is moved to the lower end of the bag 10, Thereby making it possible to extend the bag 10 in both lateral directions of the bag 10. When the zipper 20 is moved to the lower end of the bag 10 and the zipper 20 is opened, the inner skin 30 to be described later is opened so as to support both sides of the bag 10, .

2 and 6, the inner skin 30 is provided at both side edges of the bag 10 to allow the bag 10 to expand. The bag 10 can be extended to both sides by forming the inner skin 30 so as to prevent the object (the stored object) inside the bag 10 from being exposed to the outside of the bag 10. The inner cover 30 may be made of the same material as the bag 10 but is not limited thereto. The inner skin 30 is provided at both side edges of the bag 10 so as to support the side surface of the bag 10 when the zipper 20 is opened, So that the stored object can be prevented from being exposed to the outside. The inner skin 30 may be provided at a predetermined distance from an edge (zipper). When the zipper 20 is located at the upper end of the bag 10 and is in a closed state, the inner skin 30 is positioned in the bag 10 in a folded state and the zipper 20 is positioned at the lower end of the bag, The inner skin 30 is formed in an unfolded state to support both sides of the bag 10 and prevent the stored items from being exposed to the outside.

3 to 5, the zipper pull 40 is provided to connect a pair of zippers 20 provided on both side edges of the bag 10. That is, a pair of zippers 20 on the side of the bag 10 may be connected to open or close the zipper 20 at the same time, thereby facilitating expansion of both sides of the bag 10. The zipper pull 40 may be provided in the form of a bar connecting the zipper 20, but is not limited thereto. Further, the zipper pull 40 has an effect of providing a mount capable of mounting objects. That is, an umbrella, a cell phone, a key ring, a pen, etc., can be mounted on the zipper pull 40.

1 and 2, the zipper pull 40 includes a handle fixing part 50 and at least one bag fixing part 60, and the bag fixing part (not shown) 60 are provided on both sides of the bag 10. The handle fixing part 50 may be fixed to the bag fixing part 60 to fix the position of the zipper pull 40. [ Specifically, the handle fixing portion 50 and the bag fixing portion 60 may be provided with snap buttons. The handle fixing part 50 and the bag fixing part 60 can fix the zipper pull 40 to position the zipper pull 40 at a desired position so that the user can open the zipper 20 as needed There is an effect that can be. This makes it possible to prevent the zipper 20 from being opened and the both sides of the bag 10 from expanding in a situation in which the user does not want to make the bag 10 more easily available. Further, when the zipper pull 40 is used as a cradle, the zipper pull 40 can be supported.

In another aspect of the present invention, referring to Figs. 4 and 5, the zipper pull 40 is provided to be rotatable. More specifically, the zipper pull 40 is coupled to the zipper (slide of the zipper 20) so as to be rotatable, thereby making the use of the zipper 20 simpler. The connection between the zipper pull 40 and the zipper 20 may be hinged but is not limited thereto. In addition, the zipper pull 40 can be rotated to place the zipper handle 40 inside the bag 10, which allows the user to use the bag 10 in various ways.

3 and 4, the connection between the zipper pull 40 and the zipper 20 is connected using a strap 70. In this embodiment, The leather strap 70 is easy to replace, harmless to the human body, has a durability, and is not easily broken.

In another aspect of the present invention, referring to FIG. 7, a stopper 80 is provided at the lower end of the zipper 20. The lower end of the zipper 20 refers to the lower end of the bag 10 and restricts the opening of the zipper 20 to prevent the zipper 20 from being further opened. This has the effect of preventing breakage of the zipper 20 and enabling the zipper 20 to be used for a longer period of time. Further, there is an advantage that the zipper (zipper) 20 can be prevented from being misaligned in advance.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the present invention.
