Description

[Detailed description of the invention] The present invention relates to a sofa-cum-pine-rest which is made by connecting six divided cushion bodies and can be used as a pine-rest when unfolded and used as a sofa when folded and combined.

BACKGROUND ART Conventionally, a sofa-cum-pine-rest is known, in which a cushion body divided into several pieces is appropriately combined to be used as a pine-rest or a sofa.

For example, Publication of Utility Model Publication No. 52-2661, Publication of Utility Model Publication No. 52-2
There is a mattress that can be used as a sofa as disclosed in the 1966 publication, but when used as a sofa, the cushion body of the backrest part has to be stacked on top of the seat and secured with appropriate locking devices. Therefore, when a load is applied to the backrest part, the cushion body of the backrest part tends to come off, which is a major drawback.

Furthermore, since the back rest is made up of several cushion bodies stacked one on top of the other, the parting lines of the cushion bodies appear horizontally on the surface of the back rest, making it unsightly, and due to the structure of the combination, only an angular shape can be obtained. It had the disadvantage that its aesthetic appearance was poor and its value as an indoor inch rear was greatly reduced.

The object of the present invention is to eliminate these drawbacks of the conventional sofa-cum-pine-rest, and to provide a sofa-cum-pine-rest that is excellent both functionally and aesthetically.

That is, the sofa-cum-pinerest of the present invention is a cushion body having a thickness of t and a planar rectangular shape in which the surface periphery of a cushion material 7 is covered with a cover material 8; Seat lower cushion body 5 with a length of 1°,
A middle seat cushion body 4 having a length of 13, an upper seat cushion body 3 and a back side cushion body 2 having a length of 13 formed from thin to thick at an angle θ, a length of 12 and a height t at one end, and a long The upper edge of one of the lower seat auxiliary cushion body 6 and the lower seat cushion body 5 is connected to the lower edge of the seat lower cushion body 5.
The other upper edge of the middle seat cushion body 4 is connected to the other upper edge of the middle seat cushion body 4, and the other lower edge of the middle seat cushion body 4, the thin edge of the upper seat cushion body 3, and the back front cushion body 2 The thick edges of the cushion body 2 are connected to each other, and the thin edges of the front cushion body 2 and the upper edge of the rear cushion body 1 are connected to each other.

Therefore, when these connected cushion bodies are stretched out, the pinerest shown in FIG. 1 is obtained.

Lower seat auxiliary cushion body 6, lower seat cushion body 5
, the seat middle cushion body 4 and the back rear cushion body 1 have the same thickness t, and the seat upper cushion body 3 and the back front cushion body 2 are formed from thin to thick at an angle θ. Since the thickness becomes t when the inclined surfaces face each other and are overlapped, a pine tress having a constant thickness t is formed.

Each of these cushion bodies has connecting parts 9, 10, 11, 1
2 are connected to each other to form a single pine tress.

Further, since the protruding strip 16 provided on the rear cushion body 1 is positioned at the extreme end of the pinerest, it can also be used as a pillow.

When making it into a sofa, as shown in FIG. is set upright, the seat upper cushion body 3 is folded back and placed on the seat middle cushion body 4, and the back front cushion body 2 is installed in front of the back rear cushion body 1 to form a sofa. .

At this time, if t'''tt lt+13=1+ is set, the sum of the lengths of the lower seat cushion body 5 and the lower seat auxiliary cushion body 6 is 11+1°, the length of the middle seat cushion body 4, and the back rear cushion body 1. Compatibility of thickness on the convex side of 13
+η become equal, and a sofa with a perfect shape can be created.

The seat upper cushion body 3 becomes thicker toward the tip of the seat at an appropriate angle θ, and the back front cushion body 2 also becomes thicker downward at an angle θ, so that the seat and back of the sofa become thicker. The shape is extremely good.

In addition, if the thick end 14 of the upper seat cushion body 3, the thin edge 15 of the back front cushion body 2, and the rear upper edge 13 of the back rear cushion body 1 are formed with gentle curves, the sofa It also has an excellent design.

When a curved surface is formed, as shown in FIG.
The thin edge 15 of the back cushion body 1 and the rear upper edge 13 of the rear cushion body 1 are all located on the underside of the Toki mattress when it is turned into a pinerest, and the entire upper surface of the pinetress is flat, so when used as a pinetress. It does not cause any discomfort and has the same feeling of use as a normal pine mattress.

The cushioning material 7 used in the cushion body of the present invention can be any elastic cushioning material used for ordinary sofas and pinerests, such as synthetic resin foam and foam rubber.

As the surface material 8, any material used for ordinary sofas and pinerests can be used, such as woven fabric, plastic sheet, synthetic resin leather, synthetic leather 1, and natural leather.

The connection parts 9, 10, 11, and 12 of each cushion body can be made by connecting the surface covering materials 8 that cover the surface of each cushion material by sewing or other means to make the connections strong and yet flexible enough to be deformed. can do.

Since the sofa-cum-pinerest of the present invention has the above-mentioned configuration, when it is used as a sofa, the back part is formed of one cushion body in each of the front and back, and the convex strip 16 of the back rear cushion body 1 is Since it is placed under the back front cushion body 2, when the weight of a person sitting on the sofa is applied to the seat upper cushion body 3, the seat upper cushion body 3
Since the ridge 16 of the rear rear cushion body 1 is pressed down through the front rear cushion body 2 connected to the rear cushion body 2, the rear rear cushion body 1 supports the body weight in an extremely stable state without falling backward. .

Furthermore, the upper surface of the seat and the upper surface of the backrest are composed of the seat upper cushion body 3 and the back front cushion body 2 with an appropriate angle θ, so that the seat is extremely comfortable to sit on.

This has made it possible to increase the size of the backrest, which was previously considered extremely difficult in sofas constructed without using aggregate, and has increased the product value.

Furthermore, the front end of the sofa seat and the upper front and rear ends of the backrest can be made into gently curved shapes, which improves the aesthetic appearance and improves the value of the sofa as an interior decoration item.

Moreover, as shown in FIG.
Folding back and stacking the seat upper cushion body 3, back front cushion body 2, and back rear cushion body 1 on the middle seat cushion body 4 can be folded and stacked to form an S゛ rectangular parallelepiped shape. It is extremely convenient for storing this item when not in use and for packaging during transportation.

In this way, the sofa-combined pinerest of this invention is a sofa-
However, it is extremely superior in terms of function and design as a pinerest compared to conventional ones, and is practically effective.
