Description

Bed sofa with folding frame {Apparatus for having function of bed and sofa}

The present invention relates to a sofa bed having a folding frame.

Sofas and beds are often used as necessities of modern life. However, since sofas and beds are large in size, bed-use sofas that can combine sofas and beds have been proposed.

In order to achieve the above object, the combined sofa having a folding frame according to the first embodiment of the present invention, the protruding projections 72 and the jersey groove 73 is fitted to the protruding projections 72 is Each of the first and second frames 20 and 30 formed is hinged, and the second frame 30 is coupled by a multi-stage folding gear 80 so that the third frame 40 can be folded in multiple stages. The fourth frame 50 is coupled to the third frame 40 by the multi-stage folding gear 80 so that the fourth frame 50 can be folded in multiple stages, and the first, second, third, and fourth frames 20, 30, 40 50 is coated with the matrix 60 as a whole, and when the first, second, third, and fourth frames 20, 30, 40, and 50 are folded, the overall size becomes smaller.

In order to achieve the above object, the sofa bed with a folding frame according to a second embodiment of the present invention,

The first and second frames 20 and 30, each of which protrudes protruding jaw 72 and the stopping groove 73 fitted to the protruding jaw 72, are hinged to each other, and the second frame 30 is formed of a hinge. The three frames 140 are coupled by the multi-stage folding gear 80 to be folded in multiple stages, and the first metrics 65 are entirely coated on the first, second, and third frames 20, 30, and 40. The second matrix 66 is connected to the first matrix 65 by a bar, thereby folding all of the first, second, and third frames 20, 30, 40, and the second matrix 66. When folded to the lower third matrix 65 is characterized in that the overall size is reduced.

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

Figure 3 is a perspective view of a sofa bed according to a first embodiment of the present invention, Figure 4 is an excerpt side view of the simplified folding portion employed in Figure 3, Figure 5 is a folded state of the frame employed in the sofa bed of Figure 3 folded Figure 6 is a perspective view, Figure 6 is a side view showing a folded state of the sofa of Figure 5 folded. Referring to FIG. 3, the combined sofa according to the present invention includes first, second, third and fourth frames 20, 30, 40 and 50, and a matrix 60 applied to the frames. do.

The first frame 20 and the second frame 30 are coupled by the simple folding portion 70. As shown in FIG. 4, the simplified folding portion includes a hinge shaft 71 for hinge coupling the first frame 20 and the second frame 30, and a protruding jaw 72 protruding from the second frame 30. And, formed in the first frame 20 is composed of a stop groove 73 is fitted to the projection jaw (72). Since the simple folding portion 70 is a simple structure, the manufacturing cost is low and there is no balance. At this time, even if the position of the projection jaw 72 and the stop groove 73 is reversed does not affect the scope of the present invention.

A multistage folding gear 80 is installed between the second frame 30 and the third frame 40 and between the third frame 40 and the fourth frame 50, respectively. The multi-stage folding gear 80 maintains the second frame 30 and the third frame 40 or the third frame 40 and the fourth frame 50 in a folded state at a predetermined angle. Since the multi-stage folding gear is described in Korean Utility Model Registration Application No. 96-33020, its detailed description will be omitted. However, if the frame can be kept folded at a predetermined angle, the scope of the present invention is not limited by the structure of the multi-stage folding gear.

The sofa bed having such a structure serves as a bed when shown in FIG. 3 when in an unfolded state.

In a state where the first frame 20 and the second frame 30 are unfolded and the third frame 34 and the fourth frame 50 are folded, the second frame 30 and the third frame are formed by the folding gear 80. When the frame 40 is folded at a predetermined angle, for example, about 30 °, the matrix coated on the first and second frames 20 and 30 serves as a backrest folded by 30 °, so that the user can maintain a more comfortable posture. .

As shown in FIGS. 5 and 6 by the simple folding part 70 and the folding gear 80, the side parts when the first, second, third and fourth frames 20, 30, 40 and 50 are folded Becomes a '口' shape as a whole. This makes the volume smaller, easier to transport and less space for storage.

In the present embodiment, the reason why the folding gear is not used between the first frame 20 and the second frame 30 inserted in the matrix serving as the backrest is that the first frame 20 and the second frame 30 are not used. Since only needs to be unfolded or fully folded, there is no need to employ a folding gear that is folded in multiple stages. That is, since the first frame 20 and the second frame 30 only need to be folded to facilitate transportation. In addition, the folding gear is relatively expensive compared to the simple folding portion. Therefore, the production cost of the sofa bed can be lowered by not employing the folding gear.

Next, a sofa bed according to a second embodiment of the present invention will be described. Here, the same reference numerals as in FIGS. 3 to 6 are the same members having the same function.

7 is a perspective view of a sofa bed according to a second embodiment of the present invention, Figure 8 is a side view showing a partially folded bed sofa of FIG. Referring to the drawings, the sofa bed according to the second embodiment, the first, second, third frame 20, 30, 140, and the first, second, third frame 20, 30, 40 It consists of a first matrix (65) to be applied to, and a second matrix (66) connected to one end of the first matrix (65). Here, the second matrix 66 is connected by a rod or connecting portion 67 to be folded at the lower end of the first matrix 65.

The first frame 20 and the second frame 30 are coupled by a simple folding portion 70, which is the same as that employed in the first embodiment. The second frame 30 and the third frame 40 are joined by a multi-stage folding gear 80, which is also the same as that employed in the first embodiment.

The sofa bed of this structure serves as a bed, as shown in Fig. 7 when in the unfolded state.

The first frame 20 and the second frame 30 are unfolded by the simple folding part 70, and the second frame 30 and the third frame 40 are folded by the folding gear 80, and in this state. In this case, when the second matrix 66 is folded to the lower portion of the first matrix 65 around the bar portion or the connecting portion 67, the state shown in FIG. 8 becomes a state that can be used as a sofa. In this case, when the second frame 30 and the third frame 40 are folded at a predetermined angle, for example, about 60 °, the matrices coated on the first and second frames 20 and 30 serve as a backrest. You will be able to maintain a comfortable position.

At this time, when the first frame 20 is completely folded to the second frame 30 by the simple folding portion 70, the overall volume is reduced, so that it is easy to transport, and takes up less space during storage.

Although the above-mentioned sofa bed is described on the basis of two people, even one person does not affect the scope of the present invention.

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, the sofa bed with a folding frame according to the present invention can be used as a bed as well as a sofa, and at the same time can reduce the overall size by folding it is easy to carry, taking up less space when storing It is effective.
