Description

[Detailed description of the invention] (a) Purpose of the invention Industrial field of application The invention is used as a futon used as bedding, and particularly as a mattress.

Conventional technology Most conventional futons are made of a single piece of fabric, with a cushioning material such as wool, cotton, synthetic fibers, feathers, or urethane filled between the outer fabric and the lining fabric. A three-layered futon with two futons sandwiched in between is provided.

Problems that the invention aims to solve Japan has four seasons, and there are considerable differences in temperature throughout the year as well as changes in humidity, etc. In order to cope with these changes, futons are made with In winter, each person had their own futon, and on top of that, there were many types of attached bedding such as blankets and sleeping mats, and it was inconvenient to use these separately, and it was difficult to find a place to store them.

Also, no matter how many summer futons are called, the cushioning material is thin, and the outer fabric is made of a hard cloth that does not cling to the human body, so it is not something that will allow you to sleep coolly in the hot and humid summer months. Cool summer futons are in high demand.

(b) Structure of the invention This invention is a quilting method in which a half-synthetic cotton, for example, natural cotton and half-synthetic cotton such as polyester, is sandwiched between two pieces of strong fabric, and these three materials are quilted inseparably. The cloth 1 is used as the front and back cloths of a futon, and a cushioning material is filled between two quilted cloths 1, 1 to form the futon.

That is, by overlapping two pieces of strong quilting cloth 1, 1 and sewing the four circumferences, cushioning material is placed in two layers, upper and lower, in a flat rectangular space formed between the cloths 1, 1 when viewed from the side. When filling the space, a solid cotton layer 2 is provided as a cushioning material on one side of the space, and a web layer 3 is provided as a cushioning material on the other side. The hard cotton layer 2 is not a fiber aggregate state in which natural or synthetic fibers are simply arranged in a row, but is made into a state of being made firmer and less bulky than a fiber aggregate by processing such as card forming or needle punching. A layer of cotton that is batted into cotton and is sometimes coated with or sprayed with a resin-like substance to prevent it from losing its shape or becoming sag.

The web layer 3 is an irregular aggregate layer of linear synthetic resin of 0.3 to 1 mm. More specifically, by aligning the synthetic resin wires into an irregular loop shape to form a continuous disk shape in which the loop wires are intricately intertwined, and by pressing a high-temperature formwork having wavy irregularities onto this continuous disk. This is a synthetic resin linear web layer 3 having wavy irregularities on the upper and lower planes or on one side.

Therefore, in the present invention, the four circumferences of the quilting cloths 1, 1 are sewn together, and in the horizontal space formed between them,
For example, it is a futon in which a solid cotton layer 2 is provided in the lower space and a web layer 3 is provided in the upper space with the wavy unevenness facing upward,
This relates to the structure of the futon, in which a partition cloth 4 may be provided between the solid cotton layer 2 and the web layer 3 if necessary.

Function: Not only can both sides of the futon of this invention be used, but both sides can have completely different feel, feel, and effect.

That is, by using the firm cotton layer 2 side, it is possible to obtain the feel and heating effect of a conventional futon, so it can be used mainly in seasons other than summer.

If the other 3 sides of web layer are used, web layer 3
is a wire made of synthetic resin, and since it is a continuous board in the form of a loop, it has the elasticity to hold it even if the weight of the human body is applied from above. Many voids are generated between the cotton layer 2 and the cotton layer 2.

(C) Effects Since the present invention has the structure and function described above, in winter, if the person sleeps using the firm cotton layer 2 side, the body temperature of the sleeper will be accumulated in the firm cotton layer 2, allowing the sleeper to sleep warmly. If the web layer 3 side is used in the hot summer, the gaps formed by the web layer 3 will act as air circulation holes, allowing air warmed by the sleeper's body temperature to be released outside the futon from its four circumferences. By introducing cold air from outside into the futon, you can sleep cool even for long periods of sleep.

In addition, since the web layer 3 is a continuous board with a wavy uneven surface, the peaks of the unevenness stimulate the sleeping person's body surface and produce an acupressure effect, which improves blood circulation while sleeping, resulting in a different kind of restful sleep and a healthy body. can be obtained.

Furthermore, since the material of the web layer 3 is synthetic resin,
It is highly elastic and does not lose weight even over a long period of time, and has excellent bulkiness, and is extremely lightweight considering its bulkiness, making it extremely suitable as a futon, especially as a mattress.

In this case, as shown in the drawing, buttons 5 are used from the top and bottom of the quilting fabrics 1, 1, which are the front and lining fabrics, and both buttons 5, 5 are sewn together with thread to unite the four parts of the cloth and the cushioning material, and then the futon is made. It is convenient to fold the futon by providing quilting lines 6 that pass through the futon vertically at positions where the futon can be divided into three or four equal parts.
