Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a foldable mattress that utilizes the excellent properties of paulownia wood as a bedding material.

[Conventional technology]

Japanese Utility Model Publication No. 51-42580 discloses a mat in which a piece of paulownia wood whose upper four sides are cut obliquely is adhered to the surface of a flexible material such as cloth or a thin plastic film using an adhesive.

The effect is that the paulownia wood pieces conform to the curved surface of the body due to the elasticity of the rug on the bottom, the slight movement of the paulownia wood pieces improves blood circulation, and the appropriate heat balance allows you to rest. It is said that you can get a good night's sleep.

[The problem that the idea aims to solve]

Paulownia wood has a significantly smaller number of conduit structures compared to other woods, accounting for only 17.8% of the total, making it difficult to absorb moisture. In particular, tylose is well developed in the spring wood ducts, and there is little communication, which has good thermal conductivity and takes a short time to reach the body temperature after sleeping.In addition, it has good heat retention and low hygroscopicity. From this point of view, paulownia wood is the best material for bedding.

However, since the pine described in the above publication uses paulownia wood, even though it utilizes the thermal conductivity of paulownia wood, it has poor heat retention and moisture absorption properties of paulownia wood. It is difficult to say that the structure fully demonstrates the characteristic of being thin.

The problem to be solved in this invention is to provide a foldable mattress that can make maximum use of the excellent thermal conductivity and heat retention properties of paulownia wood as bedding, and in particular its low moisture absorption properties. It's about doing.

[Means to solve the problem]

The foldable mattress of the present invention has a foldable cushion body and a braided body of small pieces of paulownia wood, which has approximately the same width as the cushion body and is braided in a staggered manner, and is detachably attached to it. It is.

The small pieces of paulownia wood to be braided are made of a rectangular hexahedron having a long side about the width of an adult's thumb when viewed from above, with through holes bored at both ends of the sides.

This through-hole is made by passing string material through each small piece of paulownia wood alternately to connect the small pieces of paulownia wood in a staggered manner and braiding them. This will create a new space.

L-shaped pieces are placed at the corners of the braided body, and cylindrical pieces are placed in the recesses on the side edges to eliminate unevenness on the periphery.

Additionally, a folding pine tress made of foamed resin or a Japanese-style mattress made of cotton can be used as the cushion body.

[Effect]

Since the small pieces of paulownia wood are alternately braided in a staggered pattern, a space is formed between each small piece of paulownia wood that is completely surrounded by paulownia wood.When in use, this space is used to create a cushion located on the bottom surface and a space located on the top surface. A vacant room is formed using cloth materials such as bed sheets.

Due to the good thermal conductivity of the paulownia wood surface, the surface of the paulownia wood piece in contact with the human body is immediately heated, and at the same time, moisture from the human body also enters this cavity. However, since the hygroscopicity of paulownia wood is extremely low, the moisture within the cavity is not absorbed by the paulownia wood and remains within the cavity. Furthermore, the temperature inside the paulownia wood does not rise because the paulownia wood itself has low thermal conductivity. Therefore, the moisture within the chamber becomes saturated at this temperature, and the moisture within this chamber naturally becomes saturated and the vapor pressure increases. Most of this saturated moisture will be absorbed and diffused into the cushion material. This is always the case for the human body.
Works to maintain constant temperature and humidity.

Moreover, by combining with a folding cushion, a braided body of small pieces of paulownia wood is present within the mat in the folded state. The presence of the braided paulownia wood pieces inside the cushion body dries the cushion material, and the dry state is maintained even if the cushion material is left in the folded state for a long period of time.

〔Example〕

The attached FIGS. 1 to 4 show an example in which the mattress of the present invention is formed by combining a paulownia wood small piece braided body 2 and three tri-fold type cushion materials 7 in the form of plates.

FIG. 1 shows a state in which the cushion body 1 and the small piece braided body 2 are separated.

In the figure, the cushion material 7 is covered with a cover 8. 9 is a cover of the small piece braided body 2;
10 is a type of fastener, 10a, 10b
are fastener pieces that constitute the fastener 10. As the paulownia wood small piece braided body 2, one having the same external shape and size as the cushion body 1 is used, as shown by cutting out the cover 9.

FIG. 5 shows the braided form of the braided body 2, and FIG. 6 shows the form of the paulownia wood pieces 3 used for the braiding.

As shown in FIG. 6, the small pieces of paulownia wood 3 forming the braided body 2 are spaced apart toward the end of the long side of a hexahedron, which is a rectangle with a long side about the width of an adult's thumb when viewed from above. The one in which two through holes 4, 4 are bored at the same distance is used.

As shown in FIG. 5, a large number of the small pieces of paulownia wood 3 are braided by inserting strings 6 alternately into the through holes 4, 4 of each small piece of paulownia wood, so that the circumference is A closed space 5 completely surrounded by paulownia wood 3 is formed.

L-shaped pieces 3a are placed in the recesses at the corners of the braided body 2, and cylindrical pieces 3b are placed in the recesses on the side edges to eliminate unevenness on the periphery.

Returning to FIG. 1, at the end of the cover 9 that covers the small piece braided body 2, a fastener piece 10b forming another part of the fastener 10 is attached to a fastener piece 10a of the cushion body 1.
Sewn accordingly.

The braided body 2 having the above structure is a type of knitted fabric and is therefore foldable. Therefore, as shown in FIG. 2, the cushion body 1 covered with the cover 8 and the small piece braided body 2 covered with the cover 9 are
The two covers are fastened by the fastener 10, and the ends are connected and overlapped as shown in FIG.

Furthermore, since the cushion body 1 can be folded in three ways, and the small piece braided body 2 can be folded in the same way, the mattress can be folded as shown in FIG.

As shown in the drawing, the cushion main body 1 and the small piece braided body 2 are integrally connected by fasteners 10 attached to the covers 8 and 9, so that the mattress can be laid as shown in FIG. It is extremely convenient to both extend and fold as shown in Figure 4. For example, if it is necessary to wash the small piece braided body 2, the covers 8, 9, etc., the steps shown in FIG. The braided body 2 can be separated into small pieces.

In the embodiment, the fastener 10 is attached to one end of the mattress, but it could also be attached to the opposite end. However, due to the folding nature of the fastener 10, it is not necessary to attach it to both ends. The most preferred position for attaching the fastener 10 is at the end, but it can also be attached at the middle in a direction across the mattress.

Further, the fastener 10 may be a VeliClof fastener (trade name: Velcro tape), a hook, or the like instead of the fastener shown in the embodiment.

[Effect of idea]

The mattress of the present invention can provide the following effects.

(1) A uniform sleeping environment can be created throughout the year by controlling the humidity through the thermal conductivity of paulownia wood and the spaces present in the braided body of small pieces of paulownia wood.

(2) When sleeping, the human body does not sink into the cushion due to the braided body, and since the human body does not come into direct contact with the cushion, it does not get stuffy.

(3) When the paulownia braided body and the cushion body are folded and stored at the same time, the entire bedding is dried, which saves time and effort for drying.
