Description

{BAG FOR TREAVEL}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a traveling bag, and more particularly, to a traveling bag that includes a guide rail coupled to both sides of a luggage bag, a height adjusting device that slides up and down on the guide rail to adjust the height, And a secondary wheel coupled to the outer side of the regulating device and rotating.

BACKGROUND OF THE INVENTION [0002] Generally, a bag carrying a relatively large or heavy object, such as a travel bag, is usually provided with a moving wheel on its bottom so that it can be conveniently transported by dragging the bag, It is a well-known fact. The structure of the luggage case is shown in Fig. 1 is a perspective view showing a conventional travel bag.

The bag 10 is formed in a substantially rectangular box shape so that a space for accommodating an object can be formed therein. A handle 20 is provided at an upper portion of the bag 10, and a pair of moving wheels 30 are installed at a bottom thereof. The handle 20 is provided so as to be adjustable in length so that the bag 10 can be pulled and pulled while pulling the handle 20 as necessary to facilitate the movement of the bag 10 . The moving wheel 30 is installed at a boundary positioned on the back side from the bottom surface of the bag 10 to facilitate the transportation of the bag 10.

The traveling bag provided with the moving wheel 30 as described above allows the carrier 10 to carry the bag 10 without lifting the bag 10 directly in the process of transporting the bag 10 in a state in which the bag 10 is stored in an internal space thereof It is possible to easily move the traveling path by the moving wheel 30 in the form of dragging so that the carrier can easily carry the bag 10 without feeling a load.

However, when the traveling luggage is moved by using a staircase or an escalator, the surface of the bag comes into contact with or collides with the protrusions and corners of the stairs, thereby damaging or damaging the surface of the bag. In addition, since the surface of the bag is in contact with the stairs, a frictional force is generated and a greater load is applied to the carrier. This increases the fatigue of the user.

SUMMARY OF THE INVENTION The present invention has been developed in order to meet the above-described needs of the prior art, and it is an object of the present invention to provide a method and a device for preventing a damage or a breakage of a surface of a bag by making a transfer wheel such as a stair- , Particularly when the stairs are used, it is possible to move the bag rolling, and the load added to the carrier due to the friction between the bag surface and the stairs is eliminated, thereby reducing the fatigue of the user and providing a convenient travel bag It has its purpose.

The traveling bag according to the first embodiment of the present invention includes a guide rail coupled to both sides of a travel bag, a height raising and lowering device for raising and lowering the height of the guide rail, And an auxiliary wheel coupled to the outer side of the device and rotating.

According to the travel bag of the present invention, the auxiliary wheels are provided at the lower end of the travel bag to make it possible to more easily move the transfer path such as the stairs or the like, thereby preventing the surface of the bag from being damaged or broken, The load applied to the carrier is relieved by the frictional force caused by the contact between the surface of the bag and the stairs, thereby reducing the fatigue of the user and providing convenience in use.
