Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rotating support structure for a retractable bed,

The present invention relates to a retractable bed capable of being used for unfolding toward the floor of a room and for allowing space utilization to be increased by keeping it in a storage space formed on a wall surface or a cabinet when not in use, The present invention relates to a rotating support structure of a retractable bed which can be installed by a single person so that a retractable bed can be installed alone by combining a bed frame and a retractable bed including the same.

As urbanization progresses in recent years, the price of land in the city has risen, resulting in the construction of many houses and buildings in a narrow area, resulting in a narrower living space in the building. In particular, students who lack sufficient financial resources and beginner workers often live in a fairly small space. Specifically, a student or an office worker is accommodated in a room having a small area such as a one-room or an office-style room, thereby causing difficulties in installing furniture such as a bed, a desk, and a closet in a living space.

Among these furniture, beds are furniture that takes up a considerable space, and when installed in a small room, there is not enough room to actually live. Accordingly, in recent years, a bed is housed in a storage space formed on a wall, a cabinet, and the like, and a space in which a bed is installed is utilized as a living space.

In this way, a bed that can be spread on the floor or stored in a storage space as needed is called a retractable bed (wall bed), and the bed is rotated by connecting one side of the bed frame with a hinge.

Accordingly, there is a need for a rotation support structure for rotatably coupling the storage type bed to the storage space.

However, in the conventional rotary support structure of the retractable bed, the rotary shaft passes through the bed frame and is fixed to the wall of the storage space, or the side frame of the bed frame is rotatably coupled to the shaft structure provided on the wall. There is a problem that many workers need.

That is, since the bed frame is moved to the installation position and the bed frame is held so as not to move, a rotation shaft is installed to penetrate the bed frame or the side of the bed frame is coupled to the shaft structure of the wall. At least one operator who holds the frame is needed.

Further, since the size of the storage space in which the bed is installed is limited, a large number of workers are located in a narrow space, and the installation time of the bed frame may be longer.

In addition, in the conventional rotary support structure of the retractable bed, the bed frame is fixed to the wall by using the rotary shaft of the bed frame, so that a load of the bed frame acts on the rotary shaft, and a moment due to the rotation of the bed frame acts, There is another problem that the durability of the battery is deteriorated.

Meanwhile, as a result of investigation of the prior art related to the present invention, a large number of patent documents have been searched and some of them will be described as follows.
