In order to achieve the above object, the frame of the sofa bed according to the present invention, the main frame to which the seat back cushion is coated, and the backrest frame is coated and detachably mounted on the main frame In the frame of the sofa bed, the main frame is at least two or more first and second frames 111 and 112 for supporting the seat cushion, the first frame 111 and the second frame 112. It is characterized in that it comprises a folding portion 130 is installed between the first and second frames 111, 112 to be folded.

The apparatus further includes armrest frames 121 and 122 that are rotated by a predetermined angle at both ends of the main frames 111 and 112 and are coated with armrest cushions.

In addition, a support pillar having a predetermined height in which a screw hole 118a is formed in the first and second frames 111 and 112 and a male screw 148a is installed to be screwed into the screw hole 118a. 148 further.

Hereinafter, with reference to the accompanying drawings will be described in detail the frame of the sofa bed according to the present invention.

Figure 3 is an exploded perspective view of the frame of the sofa bed of the present invention, Figure 4 is a view showing a state in which the frame of Figure 3 folded. As shown, the frame applied to the sofa bed, the main frame 110, the seat cushion 101 is applied, and the multi-stage rotation at a predetermined angle at both ends of the main frame 110, armrest cushion 103 104 includes armrest frames 121 and 122 fitted therein.

The frame 110 is installed between the first and second frames 111 and 112 on which the seat cushions 101 and 102 are coated and between the first and second frames 111 and 112. The first and second frames 111 and 112 have a fold 130 so that they can be folded together.

Each of the first and second frames 111 and 112 has a rectangular shape. Each of the first and second frames 111 and 112 is provided with a support belt 115 for supporting the seat cushions 101 and 102 to be applied so as not to sag downward. The support belts 115 are installed to cross each other in the horizontal direction and the vertical direction to be flat, and the elasticity is good when used by pressing a material of a polystyrene system or multiple layers of wood.

The edges of the first and second frames 111 and 112 are made of thick iron pieces, and the support pieces 118 on which the screw holes 118a are formed are welded. A supporting pillar 148 supporting the first and second frames 111 and 112 is installed in the screw hole 118a, and the supporting pillar 148 is provided to support the first and second frames 111 and 112. The male screw 148a is screwed into the screw hole 118a. The number of the support posts 148 depends on the size of the first and second frames 111 and 112.

The armrest frames 121 and 122 are installed at both ends of the first and second frames 111 and 112 by the folding device 150 employing the multi-stage gear, and the armrest cushions 103 and 104 used as the armrests. ) Is coated. Here, since the folding device 150 is commonly used, a detailed description thereof will be described. At this time, of course, the scope of the present invention is not limited by the folding device 150.

Meanwhile, a plurality of holes 111a and 112a are formed at one side of the first and second frames 111 and 112, and the backrests 160 having good cushioning are installed in the holes 111a and 112a. The backrest 160 is extended with two legs, and the legs are screwed into the holes 111a and 112a so that the backrest 160 is firmly installed in the first and second frames.

In the present embodiment, in order to facilitate the description, a main frame composed of two frames has been described. However, three or four frames are used, and a folding part is provided so that each can be folded to make the size smaller when folded. Can be. Therefore, if several frames can be folded together, this technique falls within the scope of the present invention.

The operation of the frame of the sofa bed of this structure will be described.

First, when used as a sofa, after fitting the cushion to the assembled frame, and then fixed to the folding device 150 mounted on the armrest frame 121, 122 by rotating at a predetermined angle, the backrest 160 to the first, second To the frames 111 and 112. Armrest frame 121, 122 is fixed at an angle that the user can maintain the most comfortable posture. The folding device 150 may be fixed by adjusting a plurality of angles by employing five or three gears.

When used as a bed, the folding device 150 mounted on the armrest frame 121, 122 is rotated and fixed in parallel with the first and second frames 111 and 112, and the backrest 160 is removed. Since the armrest frames 121 and 122 are parallel to the first and second frames 111 and 112, the user may completely lie down.

In transportation, after removing the cushion from the assembled frame, the first and second frames 111 and 112 are folded around the fold 130 to overlap each other. The armrest frames 121 and 122 are folded to the first and second frames 111 and 112. Finally, when the support pillar 148 is removed from the first and second frames 111 and 112, as shown in FIG. 4, the frame is completely folded to reduce its size, thereby facilitating transport. Done.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.

As described above, since the frame of the sofa bed according to the present invention can be folded together, the overall size is reduced, thereby making it easy to carry.

In addition, when removing the support pillar, the frame is in close contact with the floor, so that the user can use it more comfortably.
