BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile lift-up device for facilitating the movement of furniture, and more particularly to a mobile lift-up device for moving furniture, .

Generally, furniture such as dresser, closet, dresser, drawer, living room etc. are bulky and heavy. Therefore, it is difficult for the user to move to a desired position or to change the installation position by himself or herself. Therefore, more than two people collecting power is most likely to move. To move furniture like this, lift it up to a certain height and move it. In this case, it is difficult to balance the transportation of the furniture, and when it is mistakenly handled because it requires much power to move, it is exposed to a safety accident that could injure the back of the worker or the leg. Therefore, measures are needed to move furniture safely and conveniently.

As a background of the present invention, Korean Unexamined Patent Publication No. 10-2009-0054651 discloses a 'furniture capable of moving a wheel'. A plurality of wheel mounting holes formed on both sides of the lower end portion, a body having a mounting jaw formed on the lower end of the wheel mounting hole, a plurality of wheels mounted on the wheel mounting hole of the body, A spring installed between the wheel and the wheel mounting hole for forcibly moving the wheel to the upper end of the wheel mounting hole of the body; and a spring installed inside the body for pressing the upper end of the wheel, And a driving unit for driving the driving unit.

Therefore, when the furniture is moved, the wheels can be easily moved to the lower side of the furniture body. Further, since the wheels can be moved to the inside of the furniture body when the furniture is located, it is possible to prevent the furniture from being easily moved. It is possible to prevent a safety accident occurring when heavy furniture is moved.

However, the above-described background art is a method of lifting furniture through two points when the driving unit operates, so that the furniture can not be inclined to either side. Therefore, the furniture is touched to the ground through two points of the wheel portion and the furniture legs, so that the whole point is not brought into contact with the rolling contact, so that the movement is not easy and the movement is made in an unstable posture.
