Description
この発明は、敷布団、枕、ベッドマット及びクッションに関する。 The present invention relates to a mattress, a pillow, a bed mat, and a cushion.
従来、敷布団は、掛け布団と一体的に、日本人の安らかな睡眠をとることのできる代表的な寝具であり、現状の就寝や休憩等に使用される敷布団、枕、ベッドマットあるいはクッションは、以下のとおり概括される。
１）座位や就寝位での体と敷布団との接触部の硬度を柔らかくして、体圧を広い面積で受けることにより、接触面の単位面積あたりの圧力を軽減し、圧迫感を避けるように設計されているものが一般的である。低反発枕や低反発布団は、その典型的な例である。
２）寝返りや、体動の少ないクッションが望ましいとされていた。
Traditionally, mattresses are representative bedding that can be used to sleep comfortably for Japanese people, and comforters, pillows, bed mats or cushions currently used for sleeping or resting are as follows: It is summarized as follows.
1) To reduce the pressure per unit area of the contact surface and avoid a feeling of pressure by softening the hardness of the contact part between the body and the mattress in the sitting or sleeping position and receiving body pressure over a wide area What is designed is common. A typical example is a low resilience pillow or a low resilience futon.
2) It was considered desirable to lie down and cushion with little body movement.
こうしたなかで、就寝時の体圧の集中を軽減して、就寝中に圧迫感を感じることの少ない多層マットレスの提案が知られている（例えば、特許文献１を参照）。
しかしながら、これまでの研究で、長時間維持できる理想的な姿勢はなく、数時間以上の連続的に就寝や座位を継続する場合には、特定の部位や筋肉に圧迫や緊張が生じ、循環障害や筋疲労が生じ、腰背部痛や循環障害による褥瘡などの発症要因となる。 However, in previous studies, there is no ideal posture that can be maintained for a long time. When sleeping or sitting continuously for several hours or more, compression or tension occurs in specific parts or muscles, resulting in circulatory disturbance. And muscle fatigue, causing back pain and pressure ulcers due to circulatory disturbance.
そこで、この発明は、快適な睡眠と寝覚めを保証できる敷布団、枕、ベッドマット、座位のまま疲れの少ないクッションを開発し、提供することにある。 Accordingly, the present invention is to develop and provide a mattress, a pillow, a bed mat, and a cushion with less fatigue while being in a sitting position, which can guarantee a comfortable sleep and awakening.
この発明による課題を解決するための手段としては、敷布団、枕、ベドマットおよびクッションは、複数層から構成され、就寝時の体の揺動を促進し、固定姿勢によって生じる循環障害による筋肉のこわばり、痛み、褥着（床擦れ）を予防できる敷布団、枕、ベッドマット及び長時間座位の姿勢を保持しても疲れの少ないクッションを提供するものである。 As means for solving the problems according to the present invention, the mattress, pillow, bed mat and cushion are composed of a plurality of layers, promote body swinging at bedtime, and stiff muscles due to circulatory disturbance caused by a fixed posture, The present invention provides a cushion, a pillow, a bed mat, and a cushion that can prevent fatigue and sticking (floor rubbing), and that is less fatigued even if the sitting posture is maintained for a long time.
この発明によると、敷布団、枕、ベッドマット及びクッションを複数層に形成し、表面に、体圧分散層を有する高反発性の表面材を設けており、次層に上下層とは分離した剛体で軽量のボード材を設けており、就寝中に体や頭部が沈み込むこともなくなる。更に重要な効果は、中間の該ボード材が、剛体であることによって、従来のクッションによる所謂ハンモック現象、すなわち体重によりクッションが撓みハンモック状態（谷底状態）となって体動がしにくくなる点を解消し、底部の弾性部材の弾性作用と協働して、横方向に寝返りをした場合に、横方向への体重移動に伴いボードが寝返り側に傾斜してシーソーの役目を果たすことにより、寝返りを促進する作用を発揮することで簡単に寝返りを打つことができる。このようにして、体圧分散性と、寝返りの促進作用の両者を備えた快適な敷布団、枕、ベッドマットまたはクッションを提供しようとするものである。 According to this invention, the mattress, pillow, bed mat and cushion are formed in a plurality of layers, and the surface is provided with a highly repellent surface material having a body pressure dispersion layer, and the next layer is a rigid body separated from the upper and lower layers. In addition, a lightweight board material is provided so that the body and head do not sink while sleeping. A further important effect is that the intermediate board material is a rigid body, so that the so-called hammock phenomenon by the conventional cushion, that is, the cushion bends due to the body weight and becomes a hammock state (valley bottom state), which makes it difficult to move. In the case of turning over in the horizontal direction in cooperation with the elastic action of the elastic member at the bottom, the board tilts to the side of the turn and plays the role of a seesaw as the weight moves in the horizontal direction. By demonstrating the action that promotes, you can easily turn over. In this way, it is intended to provide a comfortable mattress, pillow, bed mat or cushion having both body pressure dispersibility and an effect of promoting rolling.
以下、この発明の好適な実施の形態については、敷布団、枕、ベッドマット及びクッションにおいて、３〜５層の複層構造に形成し、表面材および底面材は体圧分散層に形成すると共に、これら表面材および底面材の中間層には、撓みの少ない剛体で軽量な素材を介して弾力体層を形成してなる敷布団、枕、ベッドマット及びクッションから構成されるものである。さらに、横方向への寝返りを促進するため、敷布団、枕、ベッドマットまたはクッションの表面層の横方向の辺縁に転げ落ち予防用の土手状の傾斜を設ける。また、最下層の弾性体層には、ボードの傾斜や揺動が容易になり、体が揺動し、寝返りしやすいように、上面方向に円錐状または半球状の凹凸を設ける。 Hereinafter, with regard to a preferred embodiment of the present invention, in the mattress, pillow, bed mat and cushion, it is formed in a multi-layer structure of 3 to 5 layers, and the surface material and the bottom material are formed in the body pressure dispersion layer, The intermediate layer of the surface material and the bottom material is composed of a mattress, a pillow, a bed mat, and a cushion in which an elastic body layer is formed through a rigid and lightweight material with little bending. Further, a bank-like slope for preventing falling down is provided on the lateral edge of the surface layer of the mattress, pillow, bed mat or cushion in order to promote rolling in the lateral direction. Further, the lowermost elastic body layer is provided with conical or hemispherical irregularities in the upper surface direction so that the board can be easily tilted and swung, and the body can swing and turn over easily.
さらに、表面層とボード層の間に、空気層を設けて、就寝開始時には空気圧を低くし、クッション性を高めて、体圧分散を高めて眠りやすくし、就寝30分後頃より空気圧を徐々に高めて高反発性にし、これにより就寝中の体の沈みこみを防ぎ揺動や寝返りを容易にする構造にする。空気圧の調整は、ポンプにタイマーを設けて適宜個人の就寝の性向に応じて時間を調整できるものとする。または、敷布団または枕に加速度センサーを設けて、体動が一定時間小さくなった時点を眠り込みと判断させ、この時点から空気圧を徐々に高める構造にしても良い。これらの理由は、眠り込むまでの30分位は、体圧分散性を高めた方が眠り込みやすいこと。眠り込んで30分位を超えると、体動を促進する構造の方が、体の血液循環の上で快適な眠りを維持できるためである。 In addition, an air layer is provided between the surface layer and the board layer to lower the air pressure at the beginning of bedtime, increase cushioning, increase body pressure dispersion, make it easier to sleep, and gradually increase the air pressure from about 30 minutes after bedtime. It has a structure that makes it easy to swing and turn over by preventing the sinking of the body while sleeping. The air pressure can be adjusted by adjusting the time according to the personal sleeping tendency by providing a timer in the pump. Alternatively, an acceleration sensor may be provided on the mattress or pillow so that the time when the body movement becomes small for a certain period of time is determined to fall asleep, and the air pressure is gradually increased from this point. The reason for this is that it is easier to fall asleep for 30 minutes before going to sleep if the body pressure dispersibility is increased. This is because the structure that promotes body movements can maintain a comfortable sleep on the blood circulation of the body after falling asleep for over 30 minutes.
次に、この発明の一実施例である3層構造とした敷布団、枕、ベッドマット及びクッションを図面に従って説明すると、図１に示すとおり、敷布団、枕、ベッドマット及びクッションにおいて、体圧分散性を有し、高反発性の弾力体からなる表面材（１）と、該表面材（１）と同じく、高反発性の弾力体からなる底面材（３）を設け、表面材（１）と底面材（３）との間に、剛体のボード材（２）を設けたことを特徴とする敷布団、枕、ベッドマット及びクッションから構成されるものである。 Next, a mattress, pillow, bed mat, and cushion having a three-layer structure according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. And a surface material (1) made of a highly resilient material, and a bottom material (3) made of a highly resilient material, like the surface material (1), and a surface material (1) It is composed of a mattress, a pillow, a bed mat and a cushion, characterized in that a rigid board material (2) is provided between the bottom material (3).
先ず、体圧分散性を有し、高反発性の弾力体からなる表面材（１）は、ラテックスを素材としており、該表面材（１）の厚みは、概略２ｃｍ程度である。ここで、最表面層のソフト感を高めるため上層をより柔らかい層とし、第二層を高反発にするなど表面材（１）を二層構成としても良い。 First, the surface material (1) having a body pressure dispersibility and made of a highly repulsive elastic body is made of latex, and the thickness of the surface material (1) is about 2 cm. Here, in order to enhance the soft feeling of the outermost surface layer, the upper layer may be a softer layer, and the surface material (1) may have a two-layer structure, for example, the second layer may have high resilience.
従来のラテックス素材は、ゴムアレルギーを起こすことがあり、これを予防するために、好適には低アレルギー・ラテックス（タンニン酸ラテックス）を使用する。 Conventional latex materials may cause rubber allergies, and hypoallergenic latex (tannic acid latex) is preferably used to prevent this.
また、底面に位置する、底面材（３）は、表面材（１）と同様にラテックスを素材としており、厚みは、５ｃｍ程度のものである。硬さは、発泡倍率を15倍、20倍そして30倍の３種類に変えることにより、そのうちから、適宜選択すればよい。 The bottom surface material (3) located on the bottom surface is made of latex as in the case of the surface material (1), and has a thickness of about 5 cm. The hardness may be selected as appropriate by changing the foaming ratio to three types of 15 times, 20 times and 30 times.
表面材（１）および底面材（３）の素材であるラテックスは、いずれも天然ゴムの発泡素材からなり、耐久性は10年あり、かつ、６〜７年で生分解される。因みに、合成ラテックスは、２〜３年で劣化してしまうことを考えると長持ちする。なお、ラテックスとは生ゴムの原料を指称する用語であり、合成ゴムの原料の場合にもいう。 Latex, which is a material of the surface material (1) and the bottom material (3), is made of a natural rubber foam material, has a durability of 10 years, and is biodegraded in 6 to 7 years. Incidentally, synthetic latex lasts a long time considering that it will deteriorate in 2 to 3 years. Latex is a term that refers to raw rubber raw materials, and also refers to synthetic rubber raw materials.
さらに、ボード材（２）の素材は、PS/PE 共重合樹脂「ピオセラン」（商標：積水化成品工業株式会社製）と呼ばれる高機能樹脂であり、高衡撃吸収性、高剛性等に優れ、しかも、リサイクル可能な発泡体からなるボード材であり、硬さ及び軽さを調整するため発泡倍率を変えたものを用いることができる。 Furthermore, the board material (2) is a high-performance resin called PS / PE copolymer resin “Piocelan” (trademark: manufactured by Sekisui Plastics Co., Ltd.), which has excellent high-strength absorption and high rigidity. And it is a board material which consists of a recyclable foam, The thing which changed foaming magnification can be used in order to adjust hardness and lightness.
そして、図２に示すように、該ボード材（２）は、発泡ポリスチレン製であり、複数の通孔（２ａ）を形成しており、これにより通気性を設けて表面材（１）と底面材（３）間に通気可能に形成しており、また、複数の通孔（２ａ）を形成することにより、表面材（１）および底面材（３）との摩擦力を確保し、これらの材がズレることを防止でき、さらに、前述のように、ボード材（２）は、軽量であると共に、倍率を変更することにより硬さも調整できる。 Then, as shown in FIG. 2, the board material (2) is made of expanded polystyrene and has a plurality of through holes (2a), thereby providing air permeability and providing the surface material (1) and the bottom surface. The material (3) is formed so as to be able to vent, and by forming a plurality of through holes (2a), a frictional force between the surface material (1) and the bottom material (3) is secured, and these As described above, the board material (2) is lightweight, and the hardness can be adjusted by changing the magnification.
この発明は、３層構造のものを示したが、４層、５層であってもよく、また、この発明の使用状態において、敷布団、枕、ベッドマット及びクッションは、就寝時、人体（Ｘ）が静上している状態では、図３（ａ）のようになり、人体が（Ｘ）が、寝返り、揺動等の体動する場合には、図３（ｂ）のようになるものである。 Although the present invention shows a three-layer structure, it may be a four-layer or five-layer structure. In the state of use of the present invention, a mattress, a pillow, a bed mat and a cushion can be used for a human body (X ) Is in a static state, as shown in FIG. 3A, and when the human body moves (X), such as turning over or swinging, as shown in FIG. 3B. It is.
ここでは、横方向への寝返りを促進するため、敷布団、枕、ベッドマットまたはクッションの表面層（１）の横方向の辺縁に転げ落ち予防用の土手状の傾斜を設ける等の改変が考慮されてよい〔図４参照〕。 Here, in order to promote turning over in the lateral direction, modifications such as providing a bank-like slope to prevent falling down on the lateral edge of the surface layer (1) of the mattress, pillow, bed mat or cushion are considered. [See FIG. 4].
さらに、最下層の弾性体層（３）には、ボード（２）の傾斜や揺動が容易になり、体が揺動し、寝返りしやすいように、上面方向に円錐状または半球状の凹凸を設ける場合も考慮される〔図４参照〕。 Further, the lowermost elastic body layer (3) has conical or hemispherical irregularities in the upper surface direction so that the board (2) can be easily tilted and swung, and the body can swing and turn over easily. Is also considered [see FIG. 4].
さらに、積極的な手段構成として、図４に示すように、表面層（１）とボード層（２）の間に、空気層（４）を設けて、就寝開始時には空気圧を低くクッション性を良くし、体圧分散性を高めることにより入眠しやすく、入眠が行われる就寝30分後頃より空気圧を徐々に高めて高反発性にし、これにより就寝中の体の沈みこみを防ぎ揺動や寝返りを容易にする構造とする場合がある。空気圧の調整は、ポンプにタイマーを設けて適宜個人の入眠の性向に応じて時間を調整できるものとする。または、敷布団の中心部に市販の加速度センサーを複数設けて、体動が一定時間（５分程度）小さくなった時点を入眠時と判断させ、この時点から空気圧を徐々に高める構造にしても良い。この理由は、就寝後入眠までの30分位は、体圧分散性を高めた方が入眠しやすいという実験結果に基づいている。入眠後は、空気圧を高めて、体の沈みこみを少なくし、寝返りや体動を促進する構造の方が、体の血液循環の図り、体の一定局所への圧力の集中を避け、褥瘡を予防し、快適な眠りを維持し、快適な寝起きを保障することができるためである。 Furthermore, as an active means configuration, as shown in FIG. 4, an air layer (4) is provided between the surface layer (1) and the board layer (2), and the air pressure is low at the start of going to bed and the cushioning property is good. However, by increasing the dispersion of body pressure, it is easy to fall asleep, and gradually increase the air pressure from about 30 minutes after going to sleep and make it highly repulsive, thereby preventing sinking of the body while sleeping and swinging and turning over In some cases, the structure is made easy. The air pressure can be adjusted by adjusting the time according to the individual's tendency to fall asleep by providing a timer in the pump. Alternatively, a plurality of commercially available acceleration sensors may be provided in the center of the mattress so that the time when the body movement decreases for a certain period of time (about 5 minutes) is determined to be asleep, and the air pressure is gradually increased from this point. . The reason for this is based on the experimental results that about 30 minutes before going to sleep after going to bed are more likely to fall asleep when the body pressure dispersibility is increased. After falling asleep, a structure that increases air pressure, reduces body sinking, and promotes turning over and body movement avoids pressure ulcers by avoiding blood pressure in the body and concentrating pressure on certain parts of the body. This is because it can prevent, maintain a comfortable sleep, and ensure a comfortable sleep.
