Description

本発明は局所荷重で生じる弾性体の局所ひずみを低減する装置に関する。 The present invention relates to an apparatus for reducing local strain of an elastic body caused by local load.

ベッドやソファなどの身体を支持する家具の多くはコイルスプリングや発泡ウレタンなど弾性体の反発弾性で身体を支持する構造であるが、反発弾性が使用者にとって小さすぎると、荷重集中部分である臀部が局所的に大きくひずみ（沈みこみ）、最も自然な状態である立位の状態（図１、１）に比べて腰椎に過度な反り返りや変形（図１、４）が発生し、かつその沈み込み（図１、６）が就寝中の姿勢変化の障害ともなり、腰椎の変形と圧迫による血流の阻害が就寝中続くため腰痛等身体の不調の原因になる。このような過度な局所ひずみを低減する従来の装置としては、該家具に載置するマットレスやクッションが知られている。（非特許文献１、２，３）   Most of the furniture that supports the body such as beds and sofas is a structure that supports the body with the resilience of elastic bodies such as coil springs and urethane foam, but if the resilience is too small for the user, the heel part that is the load concentration part Is locally significantly distorted (sinking), and the lumbar vertebrae generate excessive warping and deformation (FIGS. 1 and 4) compared to the standing state (FIGS. 1 and 1) which is the most natural state, and the sunk Inclusion (Figs. 1 and 6) is also a hindrance to postural changes during bedtime, and since the inhibition of blood flow due to deformation and compression of the lumbar spine continues during bedtime, it causes physical disorders such as low back pain. As a conventional device for reducing such excessive local distortion, mattresses and cushions placed on the furniture are known. (Non-patent documents 1, 2 and 3)

従来の局所沈みこみ低減装置としてのマットレスは、家具（ベッド・ソファ）の上に載置して、該家具弾性体の反発弾性の補完や使用者と接する面積を拡大する体圧分散で、クッションは家具弾性体の反発弾性の部分的な補完で、それぞれ局所沈みこみを低減している。しかし、以下のような課題がある。 A mattress as a conventional local sinking reduction device is a cushion that is placed on furniture (beds and sofas) to complement the resilience of the furniture elastic body and to increase the area in contact with the user, and to cushion the cushion. Is a partial complement of the resiliency of the furniture elastics, each reducing local sinking. However, there are the following issues.

＜１＞従来の局所沈みこみ低減装置で反発弾性が均質であるもの(非特許文献１、２、３)は、その反発弾性が使用者の体格・体形・体重に合わず不足する場合、製品を交換する以外には過度な局所ひずみを低減することが困難であった。 <1> A conventional device for reducing local depression which has uniform resilience (non-patent documents 1, 2 and 3) is a product when the resilience is not suitable for the user's physique, body shape and weight. It was difficult to reduce excessive local strain other than replacing the

＜２＞従来の局所沈みこみ低減装置には、弾性体の特定部分（腰部など）の反発弾性を調整、強化したもの（特許文献１，２、３）があるが、その強化部分が使用者の個々の体格・体形・体重に対して適当な位置にない場合や反発弾性が不足する場合、過度な局所ひずみを低減することが困難であり、製品全体の交換または専門業者による弾性体の部分的な交換を要し、使用者自身が手軽に調整することが困難であった。     <2> Conventional local sinking reduction devices include one that adjusts and strengthens the resilience of a specific part (such as the waist) of an elastic body (Patent Documents 1, 2 and 3). It is difficult to reduce excessive local strain if it is not in an appropriate position for individual physique, body shape or weight, or if resilience is insufficient, and replacement of the entire product or a part of an elastic body by a specialist It was difficult for users themselves to make adjustments easily.

＜３＞従来のマットレスは、ベッド全体をカバーする大きさであり一人で移動するには面積・体積・重量が大きいため、移動や洗濯・乾燥などのメンテナンスが困難であった。 The <3> conventional mattress is large enough to cover the entire bed and has a large area, volume, and weight to move by one person, making it difficult to perform maintenance such as movement, washing, and drying.

上記課題を解決するため本発明は、家具の弾性体に装着してその反発弾性を補正する装置とした。本発明は、局所荷重で生じる弾性体（ベッドやソファの家具弾性体やそれに載置されたマットレス・クッションの弾性体）の応力を、該弾性体の該局所以外の部分にも広範に分散発生させることにより該局所の応力を低減させ、応力に比例する該局所のひずみを低減させる装置とする。
具体的には、弾性体の被荷重面を被覆する布帛の部分シーツであり、不伸長性があり、弾性体に密着して局所荷重でひずみが発生する際に移動しない程度の表面摩擦をもち、該弾性体に局所荷重がかかると張力を生じて該弾性体との密着面に応力を発生させることにより該弾性体の局所ひずみ低減効果を持つ。 (図２の３)。 In order to solve the above problems, the present invention is an apparatus mounted on an elastic body of furniture to correct its resilience. The present invention widely disperses the stress of an elastic body (a furniture elastic body of a bed or a sofa and an elastic body of a mattress cushion placed thereon) generated by a local load to a portion other than the local portion of the elastic body. To reduce the local stress and reduce the local strain that is proportional to the stress.
Specifically, it is a partial sheet of a fabric covering the load-bearing surface of an elastic body, is inextensible, and has surface friction which is in intimate contact with the elastic body and does not move when strain is generated by a local load. When a local load is applied to the elastic body, a tension is generated to generate a stress on the contact surface with the elastic body, thereby having a local strain reduction effect of the elastic body. (3 in Figure 2).

本発明のシーツをベッドやソファの弾性体に被覆しその上から局所荷重がかかると、局所荷重直下は本発明のシーツを垂直下方に押し下げ、該局所荷重の縁部では周囲の本発明のシーツを荷重方向に斜めに引き込む作用を持つ。本発明のシーツは不伸長性であり、表面摩擦により該弾性体に密着し移動しないため本発明のシーツに張力が生じ、該弾性体には本シーツと接する点で張力に釣り合う応力が生じる。(図３)。 When the sheet of the present invention is coated on an elastic body of a bed or a sofa and a local load is applied from above, the sheet of the present invention is pushed downward downward directly under the local load, and the edges of the local load are surrounding sheets of the present invention. Has an action to pull in diagonally in the load direction. The sheet of the present invention is inextensible, and surface friction causes the sheet of the present invention to be in tension because it is in intimate contact with the elastic body and does not move, and a stress is generated in the elastic body at the point of contact with the sheet. (Figure 3).

本発明のシーツは、使用者の主として腰椎周辺から臀部までの位置で該弾性体の全幅方向に横断して該弾性体を被覆するので、本シーツと該弾性体との接点は局所荷重直下以外にも広範な部分に存在し、そこに上記の応力が生じる。弾性体に生じる応力の総和は該局所荷重と釣り合うので、該局所の応力はその他部分で生じる応力だけ低減され、それに比例するひずみ（沈みこみ）も低減することができる。（図２の６） Since the sheet of the present invention covers the elastic body across the entire width direction of the elastic body at a position mainly from the lumbar spine to the buttocks of the user, the contact point between the sheet and the elastic body is not under local load Also in a wide area, the above-mentioned stress occurs there. Since the total stress generated in the elastic body is balanced with the local load, the local stress is reduced by the stress generated in the other part, and the strain (sinking) proportional thereto can also be reduced. (6 in Figure 2)

＜１＞本発明は、ベッドやソファの弾性体や、その反発弾性を補完する目的で載置した従来の局所ひずみ低減装置の反発弾性が、使用者の体格・体形・体重に対して不足することにより生じる過度な局所ひずみ（沈みこみ）を低減する効果を持つ。   <1> In the present invention, the resilience of a bed or sofa or the conventional local strain reduction device placed for the purpose of complementing its resilience is insufficient for the user's body size, body shape and weight It has the effect of reducing excessive local strain (sinking) caused by

＜２＞本発明は、個々の使用者が自身の体格・体形・体重に合わせて効果を実感できる位置への調整移動することを容易にする効果を持つ。（図４） <2> The present invention has an effect of facilitating adjustment movement to a position where individual users can feel the effect according to their physical constitution, shape, and weight. (Figure 4)

＜３＞本発明は、一人で移動するに十分に小さく軽量な部分シーツであり、移設や洗濯・乾燥などのメンテナンスが容易になる効果を持つ。 <3> The present invention is a sheet sheet that is small and light enough to move by one person, and has the effect of facilitating maintenance such as relocation, washing and drying.

＜４＞本発明は、被覆する弾性体の局所の疲労劣化による反発弾性減衰（いわゆる「へたり」）の発生を遅延させる効果を持つ。   <4> The present invention has the effect of delaying the occurrence of repulsive elastic damping (so-called "swelling") due to local fatigue deterioration of the elastic body to be coated.
