Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a core of a futon.

[Conventional technology and its problems]

As is well known, futons are mainly made of cotton, and were considered unsuitable for washing. The reason for this is that when a futon is placed in a washing machine or a large rotating drum type dryer, the cotton inside clumps, shrinks, and becomes unusable.

This tendency is not so great for synthetic cotton, but
This is remarkable in the natural fiber cotton.

On the other hand, there are times when it is necessary to wash the mattresses of sick people and infants, and in such cases, wash water (liquid) from the surface of the futon to avoid damaging the cotton.
I was not able to completely wash out the inside of the cotton because I was spraying it with a brush.

In addition, the above drawbacks can be overcome to some extent by properly quilting (pressing with thread) the cotton or the cover and the cotton, as is often seen in vest pads, etc., but if the quilting intervals are wide, the effect cannot be achieved. Also, if the bed is too narrow, it will be hard and inelastic, making it uncomfortable to sleep on.

JP-A No. 51-110814 discloses a material in which a net-like material is brought into contact with one side of the cotton material, and an air layer is secured between the inner meshes to improve heat retention and breathability. A net that comes into contact with the fabric cannot prevent the cotton from twisting during washing.

The purpose of the present invention is to eliminate the disadvantages of the conventional futon, and to avoid losing its shape even if the cotton core is washed during washing, and without impairing the elasticity of the cotton during use. To provide a core of a futon that can sufficiently ensure comfort and heat retention.

[Means for solving problems]

In order to achieve the above-mentioned purpose, the present invention overlaps a net-like material of the same size on the surface of a cotton material of the size of a futon, and quilts it from above in sections of 70 cm x 60 cm or less. The gist is to create a continuous body of sections in which the entire surface of the cotton body is wrapped in the net-like body by pressing the body and the net-like body with appropriate threads.

[Effect]

According to the present invention, each compartment is relatively narrow, measuring 70 cm x 60 cm or less, and the entire cotton body is wrapped in a net-like material, so that when washing the cotton, thin threads coming out from the surface of the cotton wrap around the net-like material. It is evenly entangled with the thick fibers that make up the structure, and as a result, the net-like body and the cotton body become integrated, thereby preventing the cotton body from collapsing.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a partially cutaway perspective view showing an embodiment of a futon using the core of the present invention, Fig. 2 is a longitudinal sectional side view of the same, and Fig. 3 is an external front view. , 2 indicates a mesh body, and 3 indicates a cover.

The cotton body 1 may be made of synthetic fibers in addition to cotton yarn, but it may also be a mixture of cotton and synthetic fibers (for example, 50% each). The mesh body 2 is preferably a net made of synthetic fibers such as Tetoron or natural fibers, with a relatively fine mesh and excellent tension. The mesh may have various shapes such as a tortoise shell shape or a cross shape, and for example, those used for fishing nets may be used.

A net-like body 2 of the same size is superimposed on the top and bottom of a cotton body 1 of the size of a futon, or if the overall thickness is large as shown in the figure, a net-like body is placed inside the cotton body 1 in addition to the top and bottom. 2 to form a sandwich-like structure, and quilting 4 was appropriately applied to the entire body together with the outer cover 3. As for the shape of the quilting 4, in addition to rectangular stitching as shown in the figure, various shapes such as a cross pattern or a flower pattern can be considered.

This quilting 4 is for pressing down the cotton material 1 with the net-like material 2, and if it is too large, it will not be effective.

This invention can be used not only for mattresses and comforters, but also for zabutons, kotatsu futons, etc. Therefore, Quilting 4 can be washed depending on the purpose of use, but it must be at least 70 cm long.
A section of 60 cm or less shall be formed, and if it is larger than that, the desired effect will be less expected.

Furthermore, gauze, which has better water permeability than satin, is suitable as the material for the cover 3. This is because when quilting 4 is applied to the cotton body 1 and the net-like body 2 and they are combined together as described above, the water inside the cotton body 1 swells up when it is dehydrated and dried after washing, and this water may swell with satin having poor water permeability. This is because there is.

In addition, as another embodiment, the quilting 4 may be applied only to the cotton body 1 and the net-like body 2, and the cover may be provided as a separate body that can be simply put on later. In that case, since the cover can be washed separately, satin or other materials may be used and there is no need to limit it to gauze.

Next, to explain an example of the method for manufacturing the above-mentioned futon, as shown in Fig. 4a, a bag is made with one end open, and the net-like body 2 is fixed at appropriate points on the surface of the cover 3 facing the back side. , and its periphery is sutured to form a bag body.

In this case, as shown in the figure, the net-like body 2 may also be a bag with one end open, and the bag-like cover 3 may be covered from the outside and sewn together, or the net-like body 2 may not be made into a bag but in two pieces. may be superimposed on the upper and lower surfaces of the cover 3 with its back side facing, and sewn as appropriate as described above.

On the other hand, as shown in FIG.
As shown in the figure, turn the cover 3, which is a bag with the net-like material 2 attached to the outside, from the opening and insert the cotton material 1 inside while exposing the front side, and when it is completely inserted, quilt the entire body. Bye.

In this way, the futon of the present invention has a cotton body 1 inside.
is housed in such a way that its upper and lower surfaces are covered by the net-like body 2. Further, the area is relatively narrow and divided by quilting 4.

During washing or dehydration, many fine threads come out from the surface of the cotton body 1, and these threads are evenly entangled with the relatively thick fibers that make up the net-like body 2. As a result, the cotton body 1 becomes one with the net-like body 2, and even if the cotton body 1 tries to twist, the net-like body 2 will hold down the cotton body 1 through its tension, thereby preventing the cotton body from losing its shape. can. In addition, I experimentally repeated washing, dehydration, and drying about 20 times in a row, and was able to wash the clothes perfectly with almost no unevenness of the cotton.

[Effect of idea]

As mentioned above, the core of the futon of the present invention can be safely washed even in futons that must be made entirely or partially of natural fibers to ensure breathability, and can be used in general households. It is also very convenient for places where hygiene is particularly important, such as hospitals, infant homes, and inns.

In addition, since the net material wraps both sides of the cotton material and suppresses the cotton material from deforming, there is no need for very fine quilting, which does not impair the elasticity of the cotton material and make it uncomfortable to sleep.
