In particular, we have made special efforts to maintain the good feel characteristic of a three-fold, three-layer futon, and to completely prevent cold air from entering through the gaps.

形成する三層構造ふとんからなるものである。[Prior Art] There are futons with a three-layer structure that have a unique structure (Special Publication No. 53-8249, Publication No. 55-9234).
This three-layer futon has acupressure effect on the supine human body.
The composition of this conventional three-layer futon is that it provides a therapeutic effect, supports the body weight with appropriate cushioning properties without causing the buttocks and back to sink, and provides a correct sleeping posture. The upper layer is made of a synthetic resin foam material that has resilience against compression and has many protrusions formed on the top surface, and the middle layer is made of a synthetic resin foam material that has a certain degree of hardness against loads. The upper surface is formed with wavy irregularities, and the lower surface is formed with recesses corresponding to the wavy projections on the upper surface.The lower layer is made of an elastic synthetic resin foam material with restoring force, and the upper layer and middle layer , a three-layer futon with a lower layer laminated to form a three-layer structure as a whole.
上述した三層構造ふとんは収納・運搬を考慮し
て３つに折畳むことができる三つ折構造とされる
場合が多い。 The above-mentioned three-layer futon often has a three-fold structure that can be folded into three for storage and transportation.

率が低下した。 On the other hand, the side material that covers the three-layer structure is made by sewing and has large dimensional errors, and the fabric often sag on the surface of the futon that encloses the three-layer structure in such a side material. This caused a significant loss of aesthetic appearance. In addition, attempts have been made to solve the above problem by making the side fabric smaller in size, but the hardness of the middle layer makes it difficult to fit the fabric into the side fabric, resulting in lower assembly efficiency.

解決される。[Means for solving the problem] The above-mentioned problem is that the upper layer is made of a synthetic resin foam material that has resilience against compression, and a large number of protrusions are formed on the upper surface, and the middle layer is resistant to loads. In contrast, it is made of synthetic resin foam that has a certain degree of hardness, and has wavy unevenness formed on its upper surface, and recessed portions formed on its lower surface at locations corresponding to the wavy protrusions on the upper surface. The upper layer, the middle layer, and the lower layer are laminated to form a three-layer structure as a whole, and the three-layer structure is made of an elastic synthetic resin foam material that has a restoring force. In a three-layer futon that is divided into equal parts, the three-layer structure divided into approximately three equal parts is connected by an exterior side material that covers the three-layer structure, and the three-layer structure divided into approximately three equal parts is connected by an exterior side fabric that covers the three-layer structure. The problem is solved by a three-fold three-layer futon, characterized in that a side plate made of a synthetic resin foam material having almost the same elastic restoring force as the upper and middle layers is provided on the peripheral end surface of the middle layer of the three-layer structure. .

である。 FIG. 1 is a partially cutaway perspective view showing an embodiment of the three-layer futon according to the present invention, and FIG.
FIG. 2 is a schematic partially enlarged sectional view of the figure. Three layer structure 1
The head part 1a, the waist part 1b, and the foot part 1c are approximately divided into three equal parts, each covered by an exterior side fabric 9, and the upper or lower edge of the opposing surface 9a of the side fabric 9 is connected to form three parts. It has a tri-fold structure that can be folded into two. The three-layer structure 1 includes a lower layer 5 made of a synthetic resin foam material such as polyurethane foam that has an elastic restoring force and has the purpose of absorbing external vibrations that disturb sleep, and a lower layer 5 in the width direction of the futon. A wavy portion in which convex portions 4a and concave portions 4b are repeated and successive approximately parallel to each other is formed on the top surface, and a concave portion 4c is formed on the bottom surface at a location corresponding to the wavy convex portion 4a on the top surface.
The middle layer 4 is made of a synthetic resin foam material such as foamed polyethylene and has a resistance against the application of a compressive load, and the upper surface has a number of mountain-shaped protrusions 3a and a number of check-shaped recesses 3b. It is a three-layer structure in which an upper layer 3 made of a synthetic resin foam material such as polyurethane foam and having an elastic restoring force against compression is laminated.

るものである。 The middle layer 4 is a wavy body having a certain degree of hardness, and firmly supports the weight of the supine human body M, so that the middle layer 4 is properly supported without causing heavy parts such as the buttocks and back to sink excessively. It provides a sleeping position, corrects the distortion of the spine caused by uncomfortable postures during the day (manipulative effect), and has the effect of relieving or curing disorders such as lower back pain. Further, the upper layer 3 softens the weight support by the middle layer 4 (particularly the convex portions 4a), and provides an effect (acupressure effect) in which the numerous convexities 3a of the upper layer 3 press against the human skin surface.

A side plate 2 made of a synthetic resin foam material having an elastic restoring force against compression, such as foamed polyurethane or foamed polyethylene, is provided at the peripheral end surface portion of the middle layer 4 on each peripheral end surface 1k. Since the upper layer 4, the lower layer 5, and the side plate 2 are made of substantially the same type of elastic material, the end surface 4d of the middle layer 4 is positioned inside the end surfaces of the upper layer and the lower layer, as shown in FIGS. 1 and 2. The difference in level between the end face 4d of the middle layer and the end faces of the upper and lower layers caused by this is buried by the side plate 2.

のである。 In addition, in FIG. 1, an ion battery band 7 is shown, and the ion battery band 7 is disposed on the upper surface of the upper layer 3 via a wrapper 8 at the foot, for example, and the control device 11 Connecting cord 12, connecting connector 1
3. Applying a high voltage negative charge to the ion battery band 7 through the wiring cord 10 prevents the human body from becoming acidic and performs negative potential therapy during sleep, which has a therapeutic effect on back pain, stiff shoulders, insomnia, etc. It is something that can be done.

The lower surface of the middle layer 4 has wavy convex portions 4a and concave portions 4b.
In FIG. 3, the lower surface of the upper layer 3 does not lie along the concave portion 4b of the middle layer 4, but instead lies on the convex portion 4a.
However, in any case, the effects unique to the present invention, which will be described later, are not affected.

The entire three-layer structure has a soft and pleasant feel. In addition, on the opposing surfaces (portion 9a in Fig. 1) where the three-fold side panels are connected, which was a problem with conventional three-layer futons, the elastic force of the side panels causes pressure between the opposing surfaces. Since a biasing force is applied, there is no room for a gap to occur, and cold air is completely prevented from entering the futon, allowing a more comfortable and restful sleep state to be obtained.
