DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress, more specifically, a type in which a core material is a foldable type made of a relatively hard material such as foamed polyethylene, and provided with a belt which facilitates transportation and storage. It is about mattresses.

[0002]

2. Description of the Related Art In the case of a relatively lightweight mattress using urethane foam as a core material, it is easy to handle at the time of transportation and storage. For example, as in the mattress of Japanese Utility Model Publication No. 8-8681, a relatively lightweight mattress such as polyethylene is used. In the case of a multilayer structure using a hard core material, it has a certain weight and is difficult to carry because it is difficult to hold, and it is difficult to set up when folded up when stored and cannot be set up.

[0003]

As described above, the conventional relatively heavy foldable mattress described above has a problem that it is difficult to handle during transportation and storage, and the present invention solves such a problem. The task is to provide no mattress.

[0004]

The present invention is divided into an intermediate portion, a lower portion and an upper portion which is shorter than the intermediate portion, and the respective portions are connected on an upper surface side or a lower surface side via a side cloth,
A belt extending from the lower back surface to the entire length of the upper back surface is provided, and the belt is sewn to the side fabric from the back surface and the inner surface of the lower portion to the inner surface facing the inner surface of the intermediate portion and the middle of the back surface. A belt is sewn from the sewn end of the belt to the upper end of the upper portion, and a non-sewn portion of the belt is passed through a buckle attached to both ends of the reinforcing band, and a joining device is attached to a tip of the buckle. The above problem is solved by using a mattress in which a lower end portion of the sewn portion of the belt is passed through a buckle attached to the lower end portion of the lower portion and a lower end thereof is attached with a connector corresponding to the connector.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front perspective view showing a spread state of a mattress 1 according to the present invention, and FIG. 2 is a rear perspective view of the mattress 1. The mattress 1 has an upper portion 2 on which a pillow is placed, an intermediate portion 3 with which the upper body abuts, and a leg portion. The lower part 4 is divided into three parts. The middle part 3 and the lower part 4 have substantially the same length, and the upper part 2 is shortened. Each of the parts 2 to 4 is connected on the upper surface or the lower surface via the side cloth 5. Connecting part 6 of upper part 2 and intermediate part 3 and connecting part 7 of intermediate part 3 and lower part 4
Is turned upside down (in the illustrated example, the connection portion 7 is on the upper surface side). Thus, each part 2-4
Each can be folded with the connection portions 6 and 7 inside.

A belt 8 having a length corresponding to the entire length of the mattress is fixed to the side cloth 5 on the lower surface side of the mattress 1. Although the illustrated mattress 1 is of a single size, the number of belts 8 is one, but in the case of a double size, two belts 8 are usually installed. Of course, even in the case of a single size, two belts 8 may be used. The belt 8 is sewn to the side cloth 5 over the entire back surface of the lower portion 4, and further continuously, the inner surface of the lower portion 4 (the contact surface with the intermediate portion 3) and the side surface of the intermediate portion 3 (the contact surface with the lower portion 4). The sewing is continuously performed to the middle of the intermediate portion 3 (sewn portion 8a), and the remaining portion is not sewn and is in a free state (non-sewn portion 8b).

[0007] At the sewing end in the middle of the intermediate portion 3 of the belt 8, when the belt 8 is pulled, the force is concentrated, and the sewing thread at that portion is liable to be cut or the side cloth 5 is easily torn. Preferably, a reinforced band 9 made of a strong material similar to the belt 8 is sewn from the sewn end portion of the belt 8 to the upper end of the upper portion 2 so that the non-sewn portion 8b of the belt 8 overlaps thereover. At the inner end of the reinforcing band 9, a buckle 1 with a horizontally long sun-shaped letter
No. 0 is set, and the belt 8 is passed therethrough (see FIG. 7). By doing so, the force concentrated on the sewn end of the belt 8 is dispersed throughout the reinforcing band 9, so that the sewn thread at the sewn end of the belt 8 is cut or the side cloth 5 at that portion is cut off.
Will not be torn.

A buckle 1 similar to a buckle 10 attached to the upper end of a reinforcing band 9
2 and the connector 13 is attached to the tip.
Thus, as the upper portion 2 is folded over the intermediate portion 3 from the extended state (FIG. 2), the length of the non-sewn portion 8b of the belt 8 withdrawn from the buckle 12 increases (FIG. 3).

The end of the belt 8 on the side of the sewn portion 8a extends to the lower end of the lower part 4, and the end of the buckle is similar to the buckle 10 attached to the buckle attaching band 15 sewn to the lower end of the lower surface of the lower part 4. 16 and the connector 1
3 is attached (see FIG. 8). After the parts 2 to 4 are stacked in three steps, the non-sewn part 8 b of the belt 8 pulled out from the buckle 12 is
By turning to the side, the joint 13 and the joint 14 can be connected (FIGS. 4 and 5). The belt 8 is made up of the connectors 13 and 1
The length is set in advance so that the connectors 13 and 14 are slightly pulled when the connector 4 is connected.

[0010] The mattress 1 according to the present invention having the above-described structure includes:
In the spread state, it is used in the same manner as the conventional one, but when transporting or storing (including when it is pushed in or the like and when it is leaned against a wall or the like), it is folded from the connecting parts 6 and 7 and temporarily At this time, the non-sewn portion 8b of the belt 8 is gradually pulled out from the buckle 12 (FIG. 3). Then, when the three layers are stacked, the connectors 13 and 14 are formed.
To join. Thus, the mattress 1 is firmly tightened as a whole by the belt 8 in the three-tiered state, and the mattress 1 is maintained in that state. Therefore, the mattress 1 is easily settled during transportation and storage, and does not fall down even if it is set up. Belt 8
Is sewn to the side cloth 5 and more than half thereof is sewn to the side cloth 5, and the force applied to the sewn end is dispersed to the reinforcing band 9. Since the load is not dispersed and concentrated locally,
There is no worry about the seam end fraying or tearing.

[0011]

The present invention is as described above. The mattress according to the present invention is integrally provided with a belt which surrounds the whole and firmly holds the folded state, so that the belt is not only convenient for storage but also has a belt. Carrying bags are not required because they can be carried and carried, and the belt is hidden under the mattress when the mattress is used. In addition, since more than half of the belt is sewn to the side cloth and the sewn end is reinforced by the reinforcing band, the force applied to the sewn end during transportation or the like is dispersed. There is no fear that the arrival end is frayed or the side fabric is torn,
Since the belt is fixed and the length is set in advance, there is an effect that there is no need to lose the belt or adjust the length of the belt during the tightening operation.
