Description

【０００１】
【発明の属する技術分野】
本発明は、通気性に優れ、また体圧分散性にも優れたマットレスに関する。
【０００２】
【従来の技術】
従来、身体の荷重を広い範囲に分散させ、剪断応力の負荷を軽減させることで寝心地性を良好にするとともに、通気性や脱湿気性に優れたマットレスとして、例えば、表面からスリット状溝を介して縦横交差方向に複数列の断面逆三角形の空間部をくり抜き、人体接触面部に、多数の平板型ブロック部を形成するような技術が知られており（例えば、特許文献１参照。）、平板型ブロック部により剪断力防止を図ると同時に、縦横方向に貫通する空間部により通気性向上を図るようにしている。
また、複数の発泡体層を積層したマットレスにおいて、通気性と支持力のメリハリを得るため、中間層の発泡体層に、マットレスの幅方向に貫通する空洞部を設けるような技術も知られている。（例えば、特許文献２参照。）
【０００３】
【特許文献１】
特開平１１−１９１３９号公報、第１図
【特許文献２】
特開２００１−３２７３６７号公報、第１図
【０００４】
【発明が解決しようとする課題】
ところで、前記特許文献１の場合、マットレスの厚み方向の中間部に、縦横方向に交差する縦横複数列の断面逆三角形状の空間部が形成され、特許文献２の場合、マットレスの厚み方向の中間部に、横方向に貫通する空洞部が形成されることになるが、本発明者等の研究の結果、マットレスを横方向に貫通する空間部等が存在する場合、縦方向だけに貫通する空間部だけが形成されているものに較べて、通気性がや脱湿気性等が劣ることが明らかになった。
【０００５】
そこで本発明は、通気性をより良好にすることで、脱湿気性等を向上させると同時に、体圧分散効果の高いマットレスを提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するため本発明は、下面に通気用縦溝が形成されているマットレス、または厚み方向の中間部に通気用縦穴が形成されているマットレス、または下面に通気用縦溝が形成され且つ厚み方向の中間部に通気用縦穴が形成されているマットレスにおいて、前記通気用縦溝及び通気用縦穴を、縦方向の端面からもう一方の縦方向の端面に連通させるようにし、横方向の端面には開口させないようにした。
【０００７】
このように、通気用縦溝または通気用縦穴として、マットレスの縦方向にだけ貫通させて、横方向には開口させないことにより、通気性をより高め、脱湿気性等を向上させるようにする。
ここで、マットレスの縦方向にだけ貫通する通気用縦溝または通気用縦穴を設けると通気性や脱湿気性等がより良好になる理由は、マットレスの通気性は、寝返り等の際のポンピング作用に左右されるところが多いと思われ、この寝返り等の際に、マットレスの横方向に貫通する横溝や横穴が存在すると、寝返りによって荷重移動がなされた箇所だけの横溝や横穴が局部的に通気されるだけで、例えば、上半身を主体に寝返りをうった時には、下半身を含めたマットレス全体の通気が不充分になるからだと思われる。
これに対して、縦方向にだけ貫通する縦溝や縦穴が存在すると、寝返り時に荷重移動がなされた箇所が上半身や下半身だけに限定された場合でも、縦長方向に通気がなされ、マットレス全体の通気性が良好となるものと思われる。
【０００８】
ここで、マットレスの縦方向とは、人体の頭部と足部を結ぶ方向であり、横方向とは、それに直交する方向である。
尚、本マットレスの形態は任意であり、上下に複数層が積層される積層構造であっても良く、単層構造であっても良い。
【０００９】
また本発明では、前記マットレスを、複数のクッション材からなる積層体とし、これらクッション材のうち、少なくとも最上部のクッション材を、通気度１〜３ｄｍ３／ｓの低反発弾性フォームとした。
【００１０】
このように、最上部のクッション材を低反発弾性フォームにすれば、体圧分散効果が向上し、また、通気度を１〜３ｄｍ３／ｓにすることで、通気性も良好になる。
ここで、低反発弾性とは、反発弾性率（所定の高さから鋼球を落下させた場合の反発距離との比）が２０％以下のものをいう。また、積層体の積層数等は任意である。
尚、下層のクッション材は反発弾性率が４５％程度以上の硬めで且つ通気性の良い（通気度１．５ｄｍ３／ｓ以上）フォーム材が好ましいが、必ずしもこれに限られるものではない。
【００１１】
また本発明では、前記上層のクッション材とその下層のクッション材には、各積層面に、横方向に向けて延出する複数列の凹条部と凸条部を形成し、この凹条部と凸条部を相互に嵌合自在にするとともに、両者を嵌合させて積層した際、凹条部底面と凸条部頂面との間に、前記通気用縦溝または通気用縦穴に連通する隙間が形成されるようにした。
【００１２】
このように、上下のクッション材に凹条部と凸条部を設けて両者を嵌合させるとともに、凹条部底面と凸条部頂面との間に、前記通気用縦溝または通気用縦穴に連通する隙間を形成すれば、例えば寝返り等によって隙間が潰されると、ポンピング作用により、通気用縦溝または通気用縦穴を通して通気が促進され、脱湿気性や、熱の発散効果等を高めることが出来る。
ここで、凸条部や凹条部は上下のクッション材のいずれ側に設けても良く、いずれか一方側に凹条部を設けた場合は、他方側に凸条部を設けるようにする。
【００１３】
また本発明では、前記隙間の上下方向の大きさを、頭部支持部分と、胸部支持部分と、腰部支持部分と、足部支持部分とで異ならせるようにした。
【００１４】
このように、部位別体重圧に対応して隙間の大きさを変化させることにより、ポンピング作用を一層促進させるとともに、体圧による局部的な沈み込みを防止するようにする。このため、例えば、頭部支持部分を広くし、足部支持部分をそれに次いで広くし、胸部支持部分と腰部支持部分をこれらより狭くなるようにすれば、好適である。
また、凹条部の溝幅や凸条部の突幅として、胸部支持部分と腰部支持側部分が他の部分より広くなるようにすれば、荷重の大きい腰部や胸部の隙間面積が水平に広がって、同部分のポンピング作用を一層効果的ならしめることが出来る。
【００１５】
【発明の実施の形態】
本発明の実施の形態について添付した図面に基づき説明する。
ここで図１は二層構造にした通気マットレスをカバーで覆った状態の説明図、図２は同通気マットレスの全体図、図３は同通気性マットレスの分解斜視図、図４は下層のクッション材とサイドクッション部材の説明図で、（ａ）は正面図、（ｂ）は上面図、（ｃ）は（ｂ）のＡ−Ａ線断面図、図５は上層のクッション材の説明図で、（ａ）は側面図、（ｂ）は下面図、（ｃ）は（ｂ）のＢ−Ｂ線断面図、図６は図２のＣ−Ｃ線断面図、図７は図６のＤ−Ｄ線断面図、図８は単層構造の通気マットレスの構成例図である。
【００１６】
本発明に係る通気マットレスは、特に寝返り等を行ったような際に、ポンピング作用で湿気や熱気等が効果的に排出されるようになっており、マットレスの下面または厚み方向の中間部に、縦方向にのみ貫通する通気用溝または通気用穴を備えたことを特徴としている。
【００１７】
そこで、まず図１乃至図７に基づき、本通気用マットレスを二層構造にした構成例について説明する。
このマットレス１は、図２、図３に示すように、下層のクッション材２と上層のクッション材３の二層構造にされ、この積層物の両サイドには、サイドクッション部材４が接着等により貼り付けられている。そしてこのようなマットレス１の外部には、図１に示すような布製のカバー５が被せられるようになっている。
【００１８】
前記下層のクッション材２は、実施例の場合、反発弾性率が５０％程度で通気度が３ｄｍ３／ｓ程度のポリウレタンフォームであり、また、図３、図４に示すように、その下面に、縦方向に貫通する複数列の通気用縦溝６を備えるとともに、その上面に、横方向に延出する複数列の凸条部７を備えており、この凸条部の高さｔは、人体の頭を支持する部分（図４（ｃ）の左側部分）が低く、人体の足を支持する部分（図４（ｃ）の右側部分）がそれに次いで低く、次いで人体の胸を支持する部分が低く、最後に人体の腰を支持する部分（図４（ｃ）の中央部分）が一番高くなるようにしている。
また、この凸条部７の高さｔは、腰を支持する一番高い箇所でも、後述する上層のクッション材３の凹条部８の溝の深さｄより小さい値にされている。
【００１９】
また、凸条部７の突幅ｈは、人体の頭を支持する部分や、足を支持する部分に較べて、胸を支持する部分や腰を支持する部分が若干広くなるようにされている。
【００２０】
そして、この下層のクッション材２の上部に、以下に述べる上層のクッション材３を嵌合させて積層した後、この積層物の両サイドに、通気度が低く（１ｄｍ３／ｓ程度）且つ硬めのポリウレタンフォームからなるサイドクッション部材４が貼着されるようになっており、下層のクッション材２と上層のクッション材３との間に形成される後述の隙間ｅから横方向に空気が漏れ出さないようにしている。
【００２１】
前記上層のクッション材３は、通気度が１．５ｄｍ３／ｓ程度で、反発弾性率が１％程度の低反発ポリウレタンフォームであり、図５に示すように、上面が平坦面にされるとともに、下面には、縦方向に貫通する複数列の縦溝１０と、横方向に延出する複数列の凹条部８とが交差して設けられている。そして、縦溝１０の溝の深さｇは、凹条部８の溝の深さｄより深く、また、凹条部８の溝幅ｉは、前記下層のクッション材２の対応する凸条部７の突幅ｈと同一とされ、凹条部８と凸条部７とを嵌合させることが出来るようにされている。
【００２２】
また、前記のように、凹条部８の溝の深さｄは、一番高い凸条部７の高さｔより深くされているため、凹条部８と凸条部７を嵌合させると、図６、図７に示すように、凸条部７の頂面と、凹条部８の底面との間には、横方向に延出する隙間ｅが帯状列として形成されることとなり、この隙間ｅは、頭を支持する部分（図６の左側部分）が上下方向に広く、次いで、足を支持する部分（図６の右側部分）が広く、次いで胸を支持する部分が広く、最後に腰を支持する部分（図６の中央部分）が一番狭く形成されることになる。
また、縦溝１０の溝の深さｇは、凹条部８の溝の深さｄより深いため、凹条部８と凸条部７とを嵌合させると、図７に示すように、縦溝１０によって縦方向に貫通し且つ長手方向の両端部に開口する通気用縦穴１１が形成されることになり、また、この通気用縦穴１１には、前記隙間ｅが連通することになる。
【００２３】
そして、隙間ｅの左右両端部は、サイドクッション材４によって塞がれているため、例えばマットレス１上で寝返りをうった場合に、荷重が移動する隙間ｅ部分が潰れると、ポンピング作用により、内部の空気はすべて通気用縦穴１１を流通することになり、横方向から流出することはない。
【００２４】
ところで、前記カバー５は、図１に示すように、長手方向の両端部がメッシュ部材ｍで構成されており、通気用縦穴１１を通して行われる通気性が阻害されないようにしている。尚、図中、１２は、開閉自在なファスナである。
【００２５】
以上のようなマットレス１において、例えば寝返りをうったとき、頭や肩の一部だけを移動させたような時でも、ポンピング作用により通気性縦穴１１や通気性縦溝６により通気性が促進される。また、上面のクッション材２は低反発ポリウレタンフォームであるため、体圧分散性が良好であり、寝心地を良くする効果がある。
また、隙間ｅの大きさが部位別体重圧に対応して異なっているため、ポンピング作用が一層有効になされる。
勿論、通気用縦穴１１と通気用縦溝６は、両者を併用することなく、いずれか一方だけを設けるようにしても良い。
【００２６】
ところで、本マットレスは、図７に示すように、単層構造のマットレス１にも適用可能であり、厚み方向の中間部に、縦方向に貫通する通気用縦穴１３を設けても良く、また、マットレス１下面に通気用縦溝（不図示）を形成するようにしても良い。
【００２７】
尚、本発明は以上のような実施形態に限定されるものではない。本発明の特許請求の範囲に記載した事項と実質的に同一の構成を有し、同一の作用効果を奏するものは本発明の技術的範囲に属する。
例えば、図９（ａ）（ｂ）に示すように、本マットレス１を折り畳み式にすることも可能である。
また、クッション材の数は二層に限られるものではなく、三層以上でも良い。
【００２８】
【発明の効果】
以上のように本発明は、下面に通気用縦溝が形成されているマットレス、または厚み方向の中間部に通気用縦穴が形成されているマットレス、または下面に通気用縦溝が形成され且つ厚み方向の中間部に通気用縦穴が形成されているマットレスにおいて、通気用縦溝または通気用縦穴として、縦方向にだけ貫通させて横方向に開口しないようにしたため、通気性をより高め、脱湿気性等を向上させることが出来る。
この際、マットレスを複数のクッション材からなる積層体とし、少なくとも最上部のクッション材を、通気度１〜３ｄｍ３／ｓの低反発弾性フォームとすれば、体圧分散効果が向上し、また、通気性も良好となる。
また、上層のクッション材とその下層のクッション材に凹条部と凸条部を形成し、この凹条部と凸条部を相互に嵌合自在にするとともに、両者を嵌合させて積層した際、凹条部底面と凸条部頂面との間に、通気用縦溝または通気用縦穴に連通する隙間が形成されるようにすれば、ポンピング作用をより有効に活用することが出来、通気を促進させることが出来る。
そして、この隙間の上下方向の大きさを部位別体重圧に応じて異ならせれば、ポンピング作用を一層有効ならしめることが出来、また、凹条部の溝幅や凸条部の突幅として、腰部支持側部分が他の部分より広くなるようにすれば、腰部部分の隙間の水平面積が大きくなってポンピング作用を一層効果的ならしめることが出来る。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a mattress having excellent air permeability and excellent body pressure dispersibility.
[0002]
[Prior art]
Conventionally, while distributing the body load over a wide range and reducing the load of shear stress to improve sleeping comfort, as a mattress with excellent breathability and dehumidification, for example, through a slit groove from the surface A technique is known in which a plurality of rows of hollow sections having an inverted triangular cross section are formed in the vertical and horizontal cross directions to form a large number of flat block sections on the human body contact surface (for example, see Patent Document 1). The mold block prevents the shearing force, and at the same time improves the air permeability by the space penetrating in the vertical and horizontal directions.
Also, in a mattress in which a plurality of foam layers are laminated, in order to obtain sharpness of air permeability and supporting force, there is also known a technique of providing a hollow portion penetrating in a width direction of the mattress in a foam layer of an intermediate layer. I have. (For example, see Patent Document 2.)
[0003]
[Patent Document 1]
JP-A-11-19139, FIG. 1 [Patent Document 2]
JP 2001-327367 A, FIG. 1
[Problems to be solved by the invention]
By the way, in the case of Patent Document 1, in the middle part in the thickness direction of the mattress, a space portion having a cross-section of an inverted triangular shape in a plurality of rows and columns intersecting in the vertical and horizontal directions is formed. A hollow part penetrating in the horizontal direction is formed in the part, but as a result of the research of the present inventors, if there is a space part penetrating the mattress in the horizontal direction, a space penetrating only in the vertical direction. It became clear that the air permeability and the dehumidifying property were inferior to those in which only the portion was formed.
[0005]
Therefore, an object of the present invention is to provide a mattress having a high body pressure dispersing effect while improving the dehumidifying property by improving the air permeability.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a mattress in which a vertical groove for ventilation is formed on a lower surface, or a mattress in which a vertical hole for ventilation is formed in an intermediate portion in a thickness direction, or a vertical groove for ventilation is formed on a lower surface. And in a mattress in which a vertical hole for ventilation is formed in the middle part in the thickness direction, the vertical groove for ventilation and the vertical hole for ventilation are communicated from the vertical end face to the other vertical end face, and The end face was not opened.
[0007]
In this way, by penetrating only in the vertical direction of the mattress and not opening in the horizontal direction as the vertical groove for ventilation or the vertical hole for ventilation, the air permeability is further improved, and the dehumidifying property and the like are improved.
Here, the reason for providing a vertical groove for ventilation or a vertical hole for ventilation that penetrates only in the vertical direction of the mattress is that the air permeability and dehumidifying property become better because the air permeability of the mattress is a pumping action at the time of turning over etc. If there is a lateral groove or a horizontal hole that penetrates the mattress in the horizontal direction at the time of turning over, the lateral groove or horizontal hole only at the point where the load was moved by rolling over is locally ventilated. It is thought that, for example, when the patient turns over mainly on the upper body, the ventilation of the entire mattress including the lower body becomes insufficient.
On the other hand, if there is a vertical groove or a vertical hole that penetrates only in the vertical direction, even if the point where the load is moved when turning over is limited to only the upper body and lower body, ventilation is performed in the vertical direction, and ventilation of the entire mattress It seems that the properties are good.
[0008]
Here, the vertical direction of the mattress is a direction connecting the head and the foot of the human body, and the horizontal direction is a direction orthogonal to the direction.
Note that the form of the present mattress is arbitrary, and may have a laminated structure in which a plurality of layers are laminated one above the other, or may have a single-layer structure.
[0009]
In the present invention, the mattress is a laminate made of a plurality of cushioning materials, and among these cushioning materials, at least the uppermost cushioning material is a low resilience foam having an air permeability of 1 to 3 dm 3 / s.
[0010]
In this way, if the uppermost cushioning material is made of a low-rebound resilience foam, the effect of dispersing body pressure is improved, and the air permeability is improved by setting the air permeability to 1 to 3 dm 3 / s.
Here, the low rebound resilience means one having a rebound resilience (ratio to a rebound distance when a steel ball is dropped from a predetermined height) of 20% or less. Further, the number of stacked layers and the like are arbitrary.
The lower cushion material is preferably a foam material having a rebound resilience of about 45% or more and having good air permeability (air permeability of 1.5 dm 3 / s or more), but is not necessarily limited to this.
[0011]
Further, in the present invention, the upper cushion material and the lower cushion material have a plurality of rows of concave ridges and convex ridges extending in the lateral direction on each lamination surface. And the protruding ridges are freely fitted to each other, and when the two are fitted and laminated, between the bottom surface of the concave ridge portion and the top surface of the protruding ridge portion, the venting vertical groove or the venting vertical hole communicates. Gaps are formed.
[0012]
As described above, the upper and lower cushion members are provided with the concave ridge portion and the convex ridge portion so that they are fitted to each other, and the vertical groove for ventilation or the vertical hole for ventilation is provided between the bottom surface of the concave ridge portion and the top surface of the convex ridge portion. If a gap communicating with the air gap is formed, for example, when the gap is crushed due to turning over or the like, the ventilation is promoted through the vertical groove for ventilation or the vertical hole for ventilation by the pumping action, and the dehumidifying property, the heat dissipating effect, etc. are improved. Can be done.
Here, the convex ridge and the concave ridge may be provided on either side of the upper and lower cushion members, and when the concave ridge is provided on one of the sides, the convex ridge is provided on the other side.
[0013]
Further, in the present invention, the size of the gap in the vertical direction is made different between the head supporting portion, the chest supporting portion, the waist supporting portion, and the foot supporting portion.
[0014]
As described above, by changing the size of the gap in accordance with the body weight pressure for each part, the pumping action is further promoted and the local sinking due to the body pressure is prevented. For this reason, it is advantageous, for example, if the head support part is widened, the foot support part is subsequently widened, and the chest support part and the waist support part are narrower than these.
Also, if the chest support portion and the waist support side portion are made wider than the other portions as the groove width of the concave ridge portion and the protrusion width of the convex ridge portion, the gap area between the waist and the chest portion with a large load spreads horizontally. Thus, the pumping action of the same portion can be made more effective.
[0015]

It is pasted. The outside of the mattress 1 is covered with a cloth cover 5 as shown in FIG.
[0018]
In the case of the embodiment, the lower cushion material 2 is a polyurethane foam having a rebound resilience of about 50% and an air permeability of about 3 dm 3 / s. Further, as shown in FIGS. , A plurality of rows of ventilation vertical grooves 6 penetrating in the vertical direction, and a plurality of rows of ridges 7 extending in the horizontal direction are provided on the upper surface thereof, and the height t of the ridges is The part supporting the head of the human body (the left part in FIG. 4 (c)) is low, the part supporting the feet of the human body (the right part in FIG. 4 (c)) is next low, and then the part supporting the breast of the human body. At the end, and finally the part supporting the waist of the human body (the central part in FIG. 4C) is the highest.
Also, the height t of the protruding ridge portion 7 is set to a value smaller than the depth d of the groove of the concave ridge portion 8 of the cushioning material 3 of the upper layer, which will be described later, even at the highest portion supporting the waist.
[0019]
In addition, the protruding width h of the protruding ridge portion 7 is set so that a portion supporting the chest and a portion supporting the waist are slightly wider than a portion supporting the head of the human body and a portion supporting the feet. .
[0020]
Then, after an upper cushion material 3 described below is fitted and laminated on the upper part of the lower cushion material 2, the air permeability is low (about 1 dm 3 / s) and hard on both sides of the laminate. Side cushion member 4 made of polyurethane foam is adhered, and air leaks laterally from a gap e described later formed between the lower cushion material 2 and the upper cushion material 3. I try not to.
[0021]
The upper cushioning material 3 is a low-resilience polyurethane foam having an air permeability of about 1.5 dm 3 / s and a rebound resilience of about 1%. As shown in FIG. On the lower surface, a plurality of rows of vertical grooves 10 penetrating in the vertical direction and a plurality of rows of concave ridges 8 extending in the horizontal direction intersect with each other. The depth g of the groove of the vertical groove 10 is deeper than the depth d of the groove of the concave streak portion 8, and the groove width i of the concave streak portion 8 is corresponding to the corresponding convex streak portion of the lower cushion material 2. 7 is the same as the protrusion width h, so that the concave ridge 8 and the convex ridge 7 can be fitted.
[0022]
Further, as described above, since the depth d of the groove of the concave ridge portion 8 is made deeper than the height t of the highest convex ridge portion 7, the concave ridge portion 8 and the convex ridge portion 7 are fitted. As shown in FIGS. 6 and 7, a gap e extending in the lateral direction is formed as a band-shaped row between the top surface of the convex ridge 7 and the bottom surface of the concave ridge 8. The gap e is such that the portion supporting the head (left portion in FIG. 6) is wide in the vertical direction, the portion supporting the feet (right portion in FIG. 6) is wide, and the portion supporting the chest is wide. Finally, the part supporting the waist (the central part in FIG. 6) is formed to be the narrowest.
Further, since the depth g of the groove of the vertical groove 10 is deeper than the depth d of the groove of the concave ridge 8, when the concave ridge 8 and the convex ridge 7 are fitted, as shown in FIG. The vertical groove 10 forms a vertical ventilation hole 11 that penetrates in the vertical direction and opens at both ends in the longitudinal direction. The gap e communicates with the vertical ventilation hole 11.
[0023]
Since the left and right end portions of the gap e are closed by the side cushion material 4, for example, when turning over on the mattress 1, when the gap e where the load moves is crushed, the inside of the gap e is formed by the pumping action. All of the air flows through the vertical holes 11 for ventilation, and does not flow out from the lateral direction.
[0024]
By the way, as shown in FIG. 1, both ends of the cover 5 in the longitudinal direction are formed of a mesh member m so that the air permeability formed through the vertical hole 11 for ventilation is not hindered. In the figure, reference numeral 12 denotes a fastener that can be freely opened and closed.
[0025]
In the mattress 1 as described above, for example, when turning over or when moving only a part of the head or shoulder, the air permeability is promoted by the air-permeable vertical holes 11 and the air-permeable vertical grooves 6 due to the pumping action. You. In addition, since the cushion material 2 on the upper surface is made of a low resilience polyurethane foam, the body pressure dispersibility is good, and there is an effect of improving sleeping comfort.
Further, since the size of the gap e is different depending on the body weight pressure for each part, the pumping action is more effectively performed.
Of course, the vertical hole 11 for ventilation and the vertical groove 6 for ventilation may be provided with either one without using both.
[0026]
By the way, as shown in FIG. 7, the present mattress is also applicable to a mattress 1 having a single-layer structure, and may be provided with a vertical hole 13 for ventilation which penetrates in a vertical direction at an intermediate portion in a thickness direction. A vertical groove for ventilation (not shown) may be formed on the lower surface of the mattress 1.
[0027]
Note that the present invention is not limited to the above embodiments. Those having substantially the same configuration as those described in the claims of the present invention and exhibiting the same functions and effects belong to the technical scope of the present invention.
For example, as shown in FIGS. 9A and 9B, the mattress 1 can be of a foldable type.
Further, the number of cushion materials is not limited to two layers, but may be three or more layers.
[0028]
【The invention's effect】
As described above, the present invention relates to a mattress in which a vertical groove for ventilation is formed on the lower surface, or a mattress in which a vertical hole for ventilation is formed in the middle part in the thickness direction, or a vertical groove for ventilation formed in the lower surface and has a thickness. In a mattress in which a vertical hole for ventilation is formed in the middle part of the direction, as a vertical groove for ventilation or a vertical hole for ventilation, it penetrates only in the vertical direction and does not open in the horizontal direction. Properties can be improved.
At this time, if the mattress is a laminated body composed of a plurality of cushioning materials, and at least the uppermost cushioning material is a low-rebound resilience foam having an air permeability of 1 to 3 dm 3 / s, the body pressure dispersion effect is improved, and Good air permeability is also obtained.
In addition, a concave ridge and a convex ridge are formed in the upper cushion material and the lower cushion material, and the concave ridge and the convex ridge are freely fitted to each other, and both are fitted and laminated. At this time, if a gap communicating with the vertical groove for ventilation or the vertical hole for ventilation is formed between the bottom surface of the concave portion and the top surface of the convex portion, the pumping action can be more effectively utilized, Ventilation can be promoted.
If the size of the gap in the vertical direction is made different according to the body weight pressure for each region, the pumping action can be made more effective, and as the groove width of the concave ridge portion and the protrusion width of the convex ridge portion, If the waist support side portion is made wider than the other portions, the horizontal area of the gap in the waist portion is increased, and the pumping action can be made more effective.
