Description

[Detailed Description of the Invention] The present invention relates to a sofa bed that can be mutually converted into a sofa and a bed.

Generally, there are various types of the above-mentioned sofa beds, one of which is one that is used by being tilted horizontally with respect to the seat body. However, a device using such a hinge mechanism has the disadvantage that the structure is complicated.

Therefore, as shown in FIG.
A and a pair of second cushion bodies b, b, which are shorter than the first cushion bodies a, are successively foldably connected, and the second cushion body a is placed on top of the first cushion bodies a, a. There is one that can be used as a sofa by polymerizing b and b, and as a bed by developing it as shown by the chain line in the figure. However, when using this sofa bed as a sofa, it does not have armrests and is extremely unsightly in appearance. There were disadvantages in that good performance as a sofa could not be obtained, such as the movement of bodies b and b and poor stability.

This idea was made based on the above circumstances,
The object is to provide a sofa bed which has a backrest and armrests and has a good appearance when used as a sofa, and which can be rested on the backrest with good stability.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 2 and 3. In the figure, 1 is a rectangular base. This base body 1 is constructed by covering a relatively hard elastic material 2 such as urethane foam with an exterior material 3. This base body 1 is formed with a recess 4 that is open on the bottom and front faces thereof, and the upper face portion 5 of the base body 1, which has become thinner due to the recess 4, has a base body on the lower side in the thickness direction. A first reinforcing plate 6 made of synthetic resin or plywood and formed to have approximately the same size as the planar shape of the first reinforcing plate 6 is buried therein.

On the upper surface of the base 1, like the base 1, an elastic material 7 is provided.
A seat body 9 made of a material covered with an exterior material 8 is placed thereon. This seat body 9 includes a seat 10 formed in the same rectangular shape as the planar shape of the base body 1, and a substantially U-shape across three sides of the seat 10, excluding the front end and the rear end. It consists of a supporting wall 11 that protrudes and has the same height as the base 1. In this support wall 11, the portions located on both sides of the seat portion 10 serve as armrests 12, 12, and the portion located on the rear end side serves as a backrest 13. Further, a second reinforcing plate 14 is embedded in the seat part 10 in the middle in the thickness direction thereof, and covers almost the entirety of the seat part 10. Further, the base body 1 and the seat body 9 are foldably connected at their front end sides by a connecting cloth (not shown).

On the other hand, 15 in the figure is a stool. The stool 15 is formed to have approximately the same size as the recess 4 of the base 1, and casters 16 are provided at one end of both sides in the width direction. The stool 15 is housed in the recess 4 when not in use.

According to the sofa bed having such a structure, when the seat body 9 is superimposed on the base body 1, it can be used as a sofa. At this time, since the seat body 9 has the armrests 12, 12 and the backrest 13, it has a very good appearance. Further, when the user sits on the seat 10 of the seat body 9 and leans on the backrest 13, the backrest 13 is integrated with the seat 10, so it does not shift and move. Since the U-shaped support wall 11 is formed by the support wall 11, it has sufficient strength so that it will not bend significantly backwards due to the user's load.

When used as a bed, the seat body 9 is rotated 180 degrees in front of the base body 1, as shown in FIG. Since the support wall 11 of the seat body 9 is formed to have the same height dimension as the base body 1, the bottom surface of the seat body 9 and the top surface of the base body 1 are horizontal. Therefore, this horizontal surface can be used as a bed. Also, at this time, first and second reinforcing plates 6 and 14 are embedded in the lower side in the thickness direction of the upper surface part 5 of the base body 1 and in the middle part in the thickness direction of the seat part 10 of the seat part body 9, respectively. Therefore, the relatively thin upper surface portion 5 and seat portion 10 do not bend significantly under the user's load, and the hardness of the reinforcing plates 6 and 4 is not directly transmitted to the user. . Also, when using the stool 15 as a bed, the stool 15 can be used as a second stool.
If the supporting wall 11 is housed in the U-shaped interior formed by the support wall 11 as shown in the figure or in the recess 4 of the base body 1 (not shown), it will not only not get in the way but also be placed in the seat on the side where the stool 15 is housed. part 10 or upper surface part 5
will be reinforced.

In each of the above embodiments, the base body and the seat body do not need to be connected by a connecting cloth. Also,
Other furniture, such as a table, may be used instead of the stool.

As described above, the present invention consists of a base body and a seat body placed on the upper surface of this base body, which is composed of a flat seat body and three sides of the seat body excluding the front end side. It is constructed of a support wall that extends approximately in a U-shape and has the same height as the base body. Therefore, when the seat body is placed on the base and used as a sofa, the supporting walls serve as armrests and a backrest, so the appearance is almost the same as that of a normal sofa and is extremely stylish. Furthermore, when a user sits on the seat of the seat body and leans on the support wall that serves as the backrest, the support wall is integral with the seat and has a substantially U-shape, so the user's load is It has good stability as it does not shift or bend significantly backwards. In addition, when the seat body is installed in parallel with the base body and used as a bed, the seat body is supported by support walls provided on three sides of the base body, so that the flat seat body is difficult to bend. It has great strength and can be converted into a bed simply by unfolding the seat body, making it easy to convert. Furthermore, when the stool is not in use, it is housed in the recess in the base so that it does not get in the way, and when converting the bed, the stool can be placed in the recess in the base and seat body and serve as a reinforcing member to reinforce the seat body and the upper surface. It is.
