Description

本発明は、寝姿勢の変化を考慮した寝返りしやすい敷きマットに関する。   The present invention relates to a mat that is easy to turn over in consideration of changes in sleeping posture.

良好な寝心地を提供する敷きマットとして、ポリウレタンフォームなどの弾性体にプロファイル加工、２次元裁断加工などを施して、その表面に種々の凹凸形状を形成したものが知られている。下記の特許文献等で知られている敷きマットは、表面が連続した平坦面のものとは異なり、各凸部が独立して圧縮を受けるし、前後左右に傾くものであるため身体形状に沿いやすく、体圧を均等に受けて良好な寝心地を提供している。
実開昭５３−９８６１２号公報 特開昭５５−１０８３２５号公報 As a mat for providing a good sleeping comfort, an elastic body such as polyurethane foam is subjected to profile processing, two-dimensional cutting processing, etc., and various uneven shapes are formed on the surface thereof. The mats known in the following patent documents, etc., are different from flat mats with continuous surfaces, and each convex part receives compression independently and tilts to the front, back, left, and right, so it follows the body shape. It is easy to receive body pressure evenly and provides good sleeping comfort.
Japanese Utility Model Publication No. 53-98612 JP-A-55-108325

しかしながら、このような敷マットは、身体の受ける体圧の局部集中を良好に防ぐが、実際の睡眠において、人は寝返り打って姿勢を変えることで、体圧をより分散させようとしている。
本発明は、寝姿勢の変化を考慮した敷きマットが良好な寝心地を与えるとの知見に基づいてなされたもので、ある寝姿勢から他の寝姿勢へスムーズに寝返りしやすくした構造、特に仰臥姿勢から側臥姿勢に寝返りしやすくした構造の敷きマットを提供することを目的とする。 However, such a mat has good prevention of local concentration of body pressure received by the body, but in actual sleep, a person tries to disperse by changing his posture by turning over.
The present invention was made on the basis of the knowledge that a mat that takes into account the change in sleeping posture gives good sleeping comfort, and has a structure that facilitates a smooth turning from one sleeping posture to another, particularly a supine posture. An object of the present invention is to provide a mat with a structure that makes it easy to turn over to a lateral position.

本発明者らは、上記の目的を達成するために、寝返り方向とは反対側に人体を支持する弾性部が必要であると考えて本発明を完成させた。   In order to achieve the above object, the present inventors have completed the present invention on the assumption that an elastic part for supporting a human body is required on the side opposite to the turning direction.

すなわち、本発明の敷きマットは、貫通孔を多数有する上部材が下部材の上面に接合され、前記貫通孔内にそれぞれ駒部材が挿入された構造を有する敷きマットであって、前記上部材が、前記駒部材に較べて軟らかい素材で構成されていることを特徴とする。   That is, the mat according to the present invention is a mat having a structure in which an upper member having a large number of through holes is joined to an upper surface of a lower member, and a piece member is inserted into each of the through holes. It is characterized by being made of a softer material than the piece member.

本発明の好ましい態様の敷きマットは、駒部材が、マットの幅方向中央領域では比較的硬い素材で構成され、幅方向両側領域では比較的軟らかい素材で構成されている。   In the laying mat according to a preferred aspect of the present invention, the piece member is made of a relatively hard material in the center region in the width direction of the mat, and is made of a relatively soft material in both side regions in the width direction.

また、本発明の好ましい態様の敷きマットは、下部材が、マットの幅方向中央領域で比較的硬い素材で構成され、幅方向両側領域では比較的軟らかい素材で構成されている。   In the mat according to a preferred aspect of the present invention, the lower member is made of a relatively hard material in the center region in the width direction of the mat, and is made of a relatively soft material in both side regions in the width direction.

また、本発明の好ましい態様の敷きマットは、駒部材の水平断面の差し渡しの長さが、一方向または数方向で貫通孔の水平断面の差し渡しの長さ以上にされるとともに、それ以外の方向で貫通孔の水平断面の差し渡しの長さより小さくされて駒部材の側面と貫通孔の内壁面との間に垂直通気路となる隙間を形成している。   Further, in the mat according to a preferred aspect of the present invention, the length of the horizontal cross section of the piece member is set to be equal to or longer than the length of the horizontal cross section of the through hole in one direction or several directions, and the other direction. Thus, a gap that becomes a vertical air passage is formed between the side surface of the piece member and the inner wall surface of the through hole.

また、本発明の好ましい態様の敷きマットは、下部材の上面が凹凸とされて、当該凹凸上面と上部材の下面との間に垂直通気路に繋がる水平通気路となる隙間を形成している。   Further, in the laying mat according to a preferred aspect of the present invention, the upper surface of the lower member is uneven, and a gap is formed between the uneven upper surface and the lower surface of the upper member so as to be a horizontal air passage connected to the vertical air passage. .

また、本発明の好ましい態様の敷きマットは、駒部材が、上部材の上面あたりから上方に突出している部分と突出していない部分との上下２層から構成され、上層が下層に較べて軟らかい素材で構成されている。   Further, in the mat according to a preferred aspect of the present invention, the piece member is composed of two upper and lower layers of a portion protruding upward from the upper surface of the upper member and a portion not protruding, and the upper layer is a material softer than the lower layer. It consists of

本発明の敷きマットは、上部材を駒部材より軟らかい素材で構成したので、各駒部材が人体荷重をほぼ独立して受けるとともに、前後左右に傾動して使用者の体圧の集中を抑制することはもちろん、使用者が寝返りをうつ際、各駒部材がスプリングのような機能を果して寝返り方向とは反対側の人体のいずれかの部分をしっかり支持して、使用者の寝返りを容易とする。   In the mat according to the present invention, since the upper member is made of a material softer than the piece member, each piece member receives the human body load almost independently and tilts back and forth and right and left to suppress concentration of the body pressure of the user. Of course, when the user rolls over, each piece member functions like a spring and firmly supports any part of the human body opposite the rollover direction, making it easy for the user to roll over. .

好ましい態様の敷きマットとしては、駒部材や下部材がマットの幅方向中央領域に存在するものと較べて、両側領域に存在するものを軟らかい素材で構成すれば、使用者は中央領域から両側領域へ回転しやすくなり、また、側臥姿勢では、人体の重心が比較的高い位置となるので仰臥姿勢へは戻り易い。すなわち、仰臥姿勢から側臥姿勢へ、またその反対方向に寝返りしやすくなる。   As a laying mat in a preferred mode, if the piece member and the lower member are made of a soft material that is present in both side regions compared to the case in which the piece member and the lower member are present in the central region in the width direction of the mat, Further, in the lateral posture, the center of gravity of the human body is at a relatively high position, so that it is easy to return to the supine posture. That is, it becomes easy to turn over from the supine posture to the lateral posture and in the opposite direction.

また、好ましい態様の敷きマットとして、駒部材の水平断面の差し渡しの長さを、一方向または数方向で貫通孔の水平断面の差し渡しの長さ以上とすれば、駒部材が上部材に適度に保持されて定位置からズレたり傾き過ぎたりせず、それ以外の方向で貫通孔の水平断面の差し渡しの長さより小さくすれば、垂直通気路となる隙間が形成されて蒸れも抑制される。   Further, as a preferred embodiment of the mat, if the length of the horizontal cross section of the piece member is set to be equal to or longer than the length of the horizontal cross section of the through hole in one direction or several directions, the piece member is appropriately attached to the upper member. If it is held and does not deviate from the fixed position and does not tilt too much and is smaller than the length of the horizontal cross section of the through hole in the other direction, a gap serving as a vertical air passage is formed, and stuffiness is suppressed.

また、好ましい態様の敷きマットとして、下部材の上面を凹凸とすることで垂直通気路に繋がる水平通気路を形成すれば、人体接触面から垂直通気路、水平通気路を介して敷きマットの端面に至る通気路が連通して形成されて蒸れがより抑制される。さらに、駒部材は下部材の凹凸上面の凸部に支えられている状態であるため、人体荷重により駒部材が下部材の凹凸上面部分にめり込むように沈むといった動きがあり、使用者の体圧の集中がより抑制される。   In addition, if a horizontal ventilation path connected to the vertical ventilation path is formed by making the upper surface of the lower member uneven as a layout mat of a preferred aspect, the end surface of the mat is passed from the human body contact surface through the vertical ventilation path and the horizontal ventilation path. The air passage leading to is formed in communication, and the stuffiness is further suppressed. Furthermore, since the piece member is supported by the convex portion on the concave and convex upper surface of the lower member, there is a movement that the piece member sinks so as to sink into the concave and convex upper surface portion of the lower member due to the human body load. Concentration is further suppressed.

また、好ましい態様の敷きマットとして、駒部材を、上部材の上面あたりより上方に突出している部分と突出していない部分との上下２層で構成し、上層を下層に比べて軟らかい素材で構成すれば、体圧集中の防止性（体圧分散性）と寝返りを容易とするための人体支持性とをバランス良く高められる。   Moreover, as a laying mat in a preferred mode, the piece member is composed of two upper and lower layers of a portion protruding upward from the upper surface of the upper member and a portion not protruding, and the upper layer is formed of a softer material than the lower layer. For example, the prevention of body pressure concentration (body pressure dispersibility) and the human body support for facilitating turning over can be improved in a balanced manner.

本発明の実施形態の敷きマットを図面に基づき説明する。
ここで図１は長手方向を切り欠いた本発明の基本形態の敷きマットの部分的斜視図、図２は上部材、下部材、駒部材の位置関係の説明図で、（ａ）は垂直断面図、（ｂ）は（ａ）のＡ−Ａ線断面図、図３は駒部材と貫通孔の他の形態の一例を示す説明図、図４は第１実施例の敷きマットの説明図、図５は第２実施例の敷きマットの説明図である。
本発明の敷きマット１は、図１に示すように、少なくとも駒部材２、上部材３及び下部材４で構成されるもので、例えば、下部材４の上面に多数の貫通孔５を有する上部材３を接着し、この貫通孔５内に駒部材２を挿し込んで作製する。 A mat according to an embodiment of the present invention will be described with reference to the drawings.
Here, FIG. 1 is a partial perspective view of a laying mat of the basic form of the present invention with the longitudinal direction cut away, FIG. 2 is an explanatory view of the positional relationship of an upper member, a lower member, and a piece member, and (a) is a vertical cross section FIG. 4B is a cross-sectional view taken along line AA of FIG. 3A, FIG. 3 is an explanatory view showing another example of the piece member and the through hole, and FIG. 4 is an explanatory view of the mat of the first embodiment, FIG. 5 is an explanatory diagram of a mat according to the second embodiment.
As shown in FIG. 1, the mat 1 according to the present invention includes at least a piece member 2, an upper member 3, and a lower member 4. For example, an upper mat having a plurality of through holes 5 on the upper surface of the lower member 4. The member 3 is bonded, and the piece member 2 is inserted into the through hole 5 to be manufactured.

敷きマット１は、上記の各部材を組み付けてなる部分に網布、織布、編布等からなるカバー材で被覆して得られるが、カバー材の図示は省略する。駒部材２や上部材３は、合成樹脂発泡体等の弾性を有する素材からなるもので、合成樹脂発泡体は、ポリウレタンフォーム、ポリエチレンフォーム、ラバーフォーム等が例示されるが、連続気泡で構成されて通気性があるためポリウレタンフォームが好適である。下部材４の素材は、上記の合成樹脂発泡体が好適であるが、固綿等の繊維体でもよい。   The mat 1 is obtained by covering a portion formed by assembling the above members with a cover material made of a net cloth, a woven cloth, a knitted cloth or the like, but the illustration of the cover material is omitted. The piece member 2 and the upper member 3 are made of an elastic material such as a synthetic resin foam, and the synthetic resin foam is exemplified by polyurethane foam, polyethylene foam, rubber foam, etc. Polyurethane foam is preferred because of its breathability. The material of the lower member 4 is preferably the above synthetic resin foam, but may be a fiber body such as solid cotton.

駒部材２の形状は限定されるものではないが、駒部材２自体が上部材３の貫通孔５に挿入されやすく保持されやすくするために柱状とすると良く、さらに、貫通孔５の形状との関係において、駒部材２自体が貫通孔５の内壁面で挟持されるとともに、駒部材２の側面と貫通孔５の内壁面との間に隙間を生じさせる形状にすると良い。具体的には、駒部材２の形状は、水平断面形状において、円形であっても、楕円形でも、図３（ａ）に示すような瓢箪形でも良いが、前後左右に傾動しやすいものとするために円形とするとよい。この駒部材２の大きさは、人体を適度に支持するために水平断面の面積２０〜７０ｃｍ２、厚さ４０〜６０ｍｍとすると良い。敷きマット１において、駒部材２の上面は、上部材３の上面より多少低くてもよいが人体支持性を適度とするために５〜２０ｍｍ高くすると良い。 The shape of the piece member 2 is not limited, but the piece member 2 itself may be columnar in order to be easily inserted and held in the through hole 5 of the upper member 3, and the shape of the through hole 5 In relation, the piece member 2 itself may be sandwiched between the inner wall surfaces of the through-hole 5 and may have a shape that creates a gap between the side surface of the piece member 2 and the inner wall surface of the through-hole 5. Specifically, the shape of the piece member 2 may be a circle, an ellipse, or a bowl shape as shown in FIG. It is better to make it circular. The size of the piece member 2 is preferably 20 to 70 cm 2 in horizontal section and 40 to 60 mm in thickness in order to support the human body appropriately. In the mat 1, the upper surface of the piece member 2 may be slightly lower than the upper surface of the upper member 3, but is preferably 5 to 20 mm higher in order to make the human body supportability appropriate.

敷きマット１において、駒部材２は、上部材３より硬い素材で構成するものであるが、図２に示すように、この硬い素材からなる部分（下層２２）の上面側に、人体へのあたりを弱めるために軟らかい素材からなる部分（上層２１）を設けると良い。なお、上層２１を構成する素材は、上部材３より軟らかくても良い。
この際、上層２１と下層２２の境界が、上部材３の７５％以上の高さに位置するようにする。この値が７５％未満であると人体支持性が悪化することがある。駒部材２の上層２１と下層２２との境界を、上部材３の上面あたり（上部材３の８０〜１０５％の高さであると良い。）に位置させると、人体支持性と体圧分散性のバランスが良い敷きマットとなる。 In the mat 1, the piece member 2 is made of a material that is harder than the upper member 3, but as shown in FIG. 2, on the upper surface side of the portion made of this hard material (lower layer 22) It is preferable to provide a portion (upper layer 21) made of a soft material to weaken the strength. The material constituting the upper layer 21 may be softer than the upper member 3.
At this time, the boundary between the upper layer 21 and the lower layer 22 is positioned at a height of 75% or more of the upper member 3. If this value is less than 75%, the human body support may be deteriorated. When the boundary between the upper layer 21 and the lower layer 22 of the piece member 2 is positioned around the upper surface of the upper member 3 (the height is preferably 80 to 105% of the upper member 3), human body support and body pressure dispersion A mat with a good balance of sex.

駒部材２あるいは駒部材の下層２２は、体圧分散性及び人体支持性の点で硬度１００〜６００Ｎの素材で構成すると良い。また、駒部材ごとに硬度を異ならせてもよく、例えばマットの幅方向中央領域に存在する駒部材２を幅方向両側領域に存在する駒部材２と較べて硬くすれば、側臥姿勢に導きやすい敷きマットとすることができるとともに、敷きマットの両側が相対的に軟らかいことになるので、使用者の側臥姿勢における肩や上腕部への圧迫も小さくなる。さらに、長手方向において、臀部に対応する領域に存在する駒部材２を、その周りの領域に存在する駒部材２と較べて硬くすれば臀部の沈み込みが小さくなるので使用者の寝返りをより容易とする。なお、本発明の趣旨に反しなければ上記以外の硬度の素材で駒部材２を構成してもよい。   The piece member 2 or the lower layer 22 of the piece member is preferably made of a material having a hardness of 100 to 600 N in terms of body pressure dispersibility and human body support. Further, the hardness may be different for each piece member. For example, if the piece member 2 existing in the center region in the width direction of the mat is made harder than the piece members 2 existing in both side regions in the width direction, it is easy to lead to a lateral posture. The mat can be used as a mat, and both sides of the mat are relatively soft, so that the pressure on the shoulder and upper arm in the user's lateral posture is reduced. Furthermore, if the piece member 2 existing in the region corresponding to the buttock in the longitudinal direction is hardened as compared with the piece member 2 existing in the surrounding region, the sinking of the buttock is reduced, so that the user can turn more easily. And Note that the piece member 2 may be made of a material having a hardness other than that described above unless it is contrary to the spirit of the present invention.

駒部材２の上層２１は、硬度２０〜６０Ｎ（ＪＩＳＫ６４００；Ｄ法）の素材で構成すると良い。特にこの素材としては低反発弾性ポリウレタンフォームを用いると良い。低反発弾性ポリウレタンフォームは、荷重を解放させたときに、ゆっくりと復元する性質を有するものである。   The upper layer 21 of the piece member 2 is preferably made of a material having a hardness of 20 to 60 N (JISK6400; method D). In particular, a low resilience polyurethane foam may be used as this material. The low resilience polyurethane foam has the property of slowly restoring when the load is released.

駒部材２は、敷きマット全面に均一に設ける必要はないが、マットの領域中に本発明の特徴とする構造を７０％程度以上の領域に形成することが好ましい。また、本発明の特徴とする構造の領域は、その領域において駒部材２の面積が占める割合（駒部材の表面比率）が３５〜６０％であると良い。この値が３５％未満であると、体圧分散性及び人体支持性が悪化することがあり、６０％超であると、上部材３の強度が低下して駒部材２を適切に保持できないことがある。   Although the piece member 2 does not need to be provided uniformly on the entire surface of the mat, it is preferable to form the characteristic features of the present invention in an area of about 70% or more in the area of the mat. In the region having the structure characterized by the present invention, the ratio of the area of the piece member 2 in the region (the surface ratio of the piece member) is preferably 35 to 60%. When this value is less than 35%, body pressure dispersibility and human body support may be deteriorated, and when it exceeds 60%, the strength of the upper member 3 is reduced and the piece member 2 cannot be appropriately held. There is.

上部材３には、上下に貫通する貫通孔５が多数形成されており、上部材３は貫通孔５に挿入された駒部材２をその側面から保持する機能を有する。貫通孔５の形状は、限定されるものではないが、加工コストの関係で打ち抜きで形成されるもので良く、駒部材２の形状との関係において、駒部材２をこの貫通孔５の内壁面で挟持するとともに、駒部材２の側面と貫通孔５の内壁面との間に隙間を生じさせるような形状とすると良い。具体的には、貫通孔５の形状は、水平断面形状において円形でも、楕円形でも、図３（ｂ）に示すような多角形でもよいが、駒部材２を円柱状とした場合には、楕円形あるいは四角以上の多角形とすると良い。貫通孔５の大きさは、駒部材２を貫通孔５の内壁面で挟持する箇所では、水平断面において駒部材２の差し渡しの長さと同じかそれよりも小さい差し渡しの長さとし、隙間が生じる箇所では、駒部材２の差し渡しの長さより貫通孔５の差し渡しの長さを大きくすると良い。更に、駒部材２を挟持する箇所の差し渡しの長さは、同箇所の駒部材２の差し渡しの長さより１〜１０％小さく、隙間が生じる箇所については、同箇所の駒部材２の差し渡しの長さより５〜２０％大きくすることが好ましい。貫通孔５の差し渡しの長さと駒部材２の差し渡しの長さがこのような関係であると、隙間部分に適度な垂直通気路６が形成されるとともに、駒部材２を貫通孔５の内壁面や下部部材４の上面に接着しなくても駒部材２の位置決め保持がなされるので敷きマット１自体の作製が容易である。   The upper member 3 is formed with a number of through holes 5 penetrating vertically, and the upper member 3 has a function of holding the piece member 2 inserted into the through hole 5 from its side surface. The shape of the through hole 5 is not limited, but may be formed by punching due to the processing cost. The piece member 2 is connected to the inner wall surface of the through hole 5 in relation to the shape of the piece member 2. And a shape that creates a gap between the side surface of the piece member 2 and the inner wall surface of the through-hole 5. Specifically, the shape of the through hole 5 may be a circle, an ellipse, or a polygon as shown in FIG. 3B in the horizontal cross-sectional shape, but when the piece member 2 is a cylinder, It is good to use an ellipse or a polygon more than a square. The size of the through hole 5 is a portion where the piece member 2 is sandwiched between the inner wall surfaces of the through hole 5, and is the same as or smaller than the delivery length of the piece member 2 in the horizontal section, where a gap is generated. Then, it is preferable that the passing length of the through hole 5 is larger than the passing length of the piece member 2. Further, the passing length of the part holding the piece member 2 is 1 to 10% smaller than the passing length of the piece member 2 at the same place. It is preferable to make it 5-20% larger than this. When the passing length of the through hole 5 and the passing length of the piece member 2 are in such a relationship, an appropriate vertical air passage 6 is formed in the gap portion, and the piece member 2 is connected to the inner wall surface of the through hole 5. In addition, since the piece member 2 can be positioned and held without being bonded to the upper surface of the lower member 4, the mat 1 can be easily manufactured.

上部材３は、駒部材２が前後左右に適度に傾動するように、厚さ３０〜５５ｍｍとし、硬度４０〜８０Ｎの素材で構成すると良い。また、上部材３は、敷きマット全面にわたってすべて同一の素材で構成する必要はなく、硬度４０〜８０Ｎの範囲で硬度の異なる素材を繋ぎ合わせて構成してもよい。なお、本発明の趣旨に反しなければ、上記以外の硬度の素材で上部材を構成してもよい。   The upper member 3 is preferably made of a material having a thickness of 30 to 55 mm and a hardness of 40 to 80 N so that the piece member 2 can be tilted appropriately in the front-rear and left-right directions. Moreover, the upper member 3 does not need to be composed of the same material all over the entire surface of the mat, and may be configured by joining materials having different hardnesses in the range of hardness of 40 to 80N. Note that the upper member may be made of a material having a hardness other than that described above, provided that it does not violate the gist of the present invention.

下部材４は、その上面に上部材３を接合するとともに、駒部材２を載置ないし接合するものである。下部材４の厚さは特に限定されないが２０〜８０ｍｍ程度である。また、下部材の上面を山と谷とが縞状に繰り返す凹凸あるいは山及び窪みが千鳥格子状に並んだ凹凸とすれば、垂直通気路６に繋がった水平通気路７が形成されて人体の蒸れがより軽減される。このような凹凸を有する下部材４はポリウレタンフォームの加工に汎用されるプロファイル裁断加工で成形すると良い。このような下部材は硬度１５０〜５００Ｎの素材で構成すると良い。   The lower member 4 joins the upper member 3 to the upper surface thereof, and mounts or joins the piece member 2. The thickness of the lower member 4 is not particularly limited, but is about 20 to 80 mm. Further, if the upper surface of the lower member is formed with irregularities in which peaks and valleys repeat in a stripe pattern or irregularities in which peaks and depressions are arranged in a staggered pattern, a horizontal ventilation path 7 connected to the vertical ventilation path 6 is formed, and the human body The stuffiness is reduced. The lower member 4 having such irregularities may be formed by profile cutting that is generally used for processing polyurethane foam. Such a lower member is preferably made of a material having a hardness of 150 to 500N.

また、下部材４は、敷きマット全面にわたってすべて同一の素材で構成する必要はなく、例えば幅方向の中央領域に存在する素材をその両側の領域に存在する素材と比べて硬く構成することで側臥姿勢に導きやすい敷きマットになる。   Further, the lower member 4 does not have to be formed of the same material all over the entire surface of the laying mat. For example, the material present in the central region in the width direction is configured to be harder than the materials present in the regions on both sides thereof. It becomes a mat that is easy to guide the posture.

実施例１の敷きマット１は、図１に示すように、貫通孔５を多数有する上部材３と、上部材３を上面に接合する下部材４と、前記貫通孔内に挿入した多数の駒部材２とからなり、実施例１においては、駒部材２を図４に示すように配設している。この際、駒部材２は、直径８０ｍｍ、高さ５０ｍｍの円柱形状のものを１６３個使用し、駒部材２を上下２層にするとともに、上層２１は厚さ１５ｍｍ、下層２２は厚さ３５ｍｍとし、上層の素材には密度５０ｋｇ／ｍ３、硬度４０Ｎの低反発弾性ポリウレタンフォームを用い、下層には物性の異なる５種のポリウレタンフォームを用いた。この５種の素材の物性は表１に示す通りであり、図４の駒部材２に付記した数字は、下表の丸数字に対応している。 As shown in FIG. 1, the mat 1 according to the first embodiment includes an upper member 3 having a large number of through holes 5, a lower member 4 that joins the upper member 3 to the upper surface, and a large number of pieces inserted into the through holes. It consists of the member 2, and in Example 1, the piece member 2 is arrange | positioned as shown in FIG. At this time, the piece member 2 uses 163 columnar members having a diameter of 80 mm and a height of 50 mm, the piece member 2 is divided into two upper and lower layers, the upper layer 21 is 15 mm thick, and the lower layer 22 is 35 mm thick. The upper layer material used was a low resilience polyurethane foam having a density of 50 kg / m 3 and a hardness of 40 N, and the lower layer was made of five types of polyurethane foams having different physical properties. The physical properties of these five types of materials are as shown in Table 1, and the numbers added to the piece member 2 in FIG. 4 correspond to the round numbers in the table below.

駒部材２は、他の部材とは接着されておらず、また、上部材３の上面から上方に突出してその上面を上部材３の上面より１０ｍｍ高くしている。駒部材２の側面と貫通孔５の壁面との間には部分的に垂直通気路６が形成してあり、上部材２の下面と凹凸上面を有する下部材３の上面との間には水平通気路７が形成してある。   The piece member 2 is not bonded to other members, and protrudes upward from the upper surface of the upper member 3 so that the upper surface is 10 mm higher than the upper surface of the upper member 3. A vertical air passage 6 is partially formed between the side surface of the piece member 2 and the wall surface of the through-hole 5, and is horizontally between the lower surface of the upper member 2 and the upper surface of the lower member 3 having an uneven upper surface. An air passage 7 is formed.

実施例１の駒部材２の配置にあっては、敷きマット１の頭部側Ｘと足部側Ｙを決めて使用する態様のマット構成とし、人体荷重の大きい領域、小さい領域に対応して駒部材２の硬度を異ならせるとともに、人体の胸部、腰部、臀部、下腿部に対応する領域については、各領域ごとに、幅方向中央領域の駒部材２の硬度を、幅方向両端領域の駒部材２の硬度より硬く構成した。
なお、上部材２は、全体に均一分散した１６３個の貫通孔５を有する４０ｍｍ×幅１０００ｍｍ×長さ２０００ｍｍの直方体形状ものを使用した。貫通孔５の形状はマットの長手方向の差し渡しの長さ９０ｍｍ、幅方向の差し渡しの長さ７５ｍｍの楕円形状である。上部材の素材には密度２２ｋｇ／ｍ３、硬度６０Ｎのポリウレタンフォームを用いた。
そして、この実施例では、駒部材２の存在する領域の面積中に駒部材２の面積が占める割合（駒部材２の表面比率）は４０．９％であった。 In the arrangement of the piece member 2 of the first embodiment, the mat structure has a configuration in which the head side X and the foot side Y of the laying mat 1 are determined and used, corresponding to a region where the human body load is large and a region where the human body load is small. For the regions corresponding to the chest, waist, hips, and crus of the human body, the hardness of the piece member 2 in the central region in the width direction is set to be different in the width direction end regions. It was configured to be harder than the hardness of the piece member 2.
The upper member 2 used was a rectangular parallelepiped having a size of 40 mm × width 1000 mm × length 2000 mm having 163 through holes 5 uniformly dispersed throughout. The shape of the through-hole 5 is an elliptical shape with a length of 90 mm in the longitudinal direction of the mat and a length of 75 mm in the width direction. A polyurethane foam having a density of 22 kg / m 3 and a hardness of 60 N was used as the upper member material.
In this example, the ratio of the area of the piece member 2 to the area of the area where the piece member 2 exists (the surface ratio of the piece member 2) was 40.9%.

また、下部材４は、プロファイル裁断加工を施した、厚さ（凸／凹）６０／４５ｍｍ×幅１０００ｍｍ×長さ２０００ｍｍの山及び窪みが千鳥格子状に並んだ凹凸上面を有する形状のものを使用した。下部材の素材には密度３５ｋｇ／ｍ３、硬度１８０Ｎのポリウレタンフォームを用いた。 Further, the lower member 4 has a shape having a concavo-convex upper surface in which peaks and depressions having a thickness (convex / concave) of 60/45 mm × width of 1000 mm × length of 2000 mm arranged in a staggered pattern are subjected to profile cutting. It was used. A polyurethane foam having a density of 35 kg / m 3 and a hardness of 180 N was used as the lower member material.

このような実施例１の敷きマット１において、特に仰臥姿勢から側臥姿勢への寝返りが容易であり、また、体圧が分散されると同時に蒸れにくいため、寝心地性は良好であった。
更に、駒部材２が接着されていないため、使用者の体型に適するような敷きマットを作製するにあたって、不適な駒部材を適する駒部材に簡単に変更できるという特徴がある。 In the laying mat 1 of Example 1, it was particularly easy to turn over from a supine posture to a side-by-side posture, and since the body pressure was dispersed and at the same time, it was difficult to stuffy, the sleeping comfort was good.
Furthermore, since the piece member 2 is not bonded, there is a feature that an unsuitable piece member can be easily changed to a suitable piece member when producing a mat that is suitable for the user's body shape.

前記実施例１の敷きマットとは一部異なって、上部材３の頭部側Ｘ端部領域と、足部側Ｙ端部領域については貫通孔のないポリウレタンフォームから作製し（厚みは実施例１と同一）、頭部側Ｘと足部側Ｙの貫通孔のない端部領域の上部材３を、密度３０ｋｇ／ｍ３、硬度１３０Ｎのポリウレタンフォームにするとともに、その他の領域の上部材３や、下部材４や、貫通孔５などは実施例１と同一とし、駒部材２については下層２２の物性を代えた以外は同一として敷きマット１を作製し、実施例２とした。この場合の駒部材２の表面比率も４０．９％であり、この実施例２を図５に示す。 Unlike the laying mat of the first embodiment, the head side X end region and the foot side Y end region of the upper member 3 are made of polyurethane foam having no through-holes (thickness is that of the embodiment). 1), the upper member 3 of the end region without the through holes on the head side X and the foot side Y is made of polyurethane foam having a density of 30 kg / m 3 and a hardness of 130 N, and the upper member 3 in other regions The lower member 4, the through hole 5, and the like are the same as those in the first embodiment, and the piece mat 2 is manufactured in the same manner as the second embodiment except that the physical properties of the lower layer 22 are changed. The surface ratio of the piece member 2 in this case is also 40.9%, and Example 2 is shown in FIG.

この実施例２の敷きマット１においても、実施例１のと同様な特徴を有するものであった。   The laying mat 1 of Example 2 also had the same characteristics as in Example 1.

実施例１に示す敷きマットと素材、駒部材２の配置等は共通するが、長手方向を分割した態様とし、図６に示すようにＡ〜Ｇの７個の独立した部分で構成される敷きマット１を作製した。この敷きマット１のカバー材での被覆は、図７に示すように、Ａ、Ｂを内カバーＴで被覆し、Ｃ、Ｄ、Ｅを内カバーＵで被覆し、Ｆ、Ｇを内カバーＶで被覆して３個の被覆部材を作製し、これら３個の被覆部材を三つ折り可能とした外カバーＷの三つの袋部に挿入することにより行った。なお、内カバーＴ、Ｕ、Ｖと外カバーＷは網状の生地で形成した。   Although the layout of the mat and the material, the piece member 2 and the like shown in the first embodiment are the same, the longitudinal direction is divided, and the mat is composed of seven independent parts A to G as shown in FIG. A mat 1 was produced. As shown in FIG. 7, the covering mat 1 is covered with an inner cover T, C, D and E are covered with an inner cover U, and F and G are covered with an inner cover V as shown in FIG. The three covering members were produced by covering with three, and the three covering members were inserted into the three bag portions of the outer cover W capable of being folded in three. The inner covers T, U, V and the outer cover W were formed of a net-like cloth.

実施例３の敷きマット１は、実施例１の敷きマットと同様な特徴を有することは勿論、マットの長手方向を複数の独立した部材で構成するようにしていることにより、使用者の体型に適するような敷きマットを作製するにあたって、不適な部材を適する部材に簡単に変更できるという特徴がある。   The laying mat 1 of the third embodiment has the same characteristics as the laying mat of the first embodiment, and of course, the longitudinal direction of the mat is composed of a plurality of independent members, so that the user's body shape can be obtained. In producing a suitable mat, there is a feature that an unsuitable member can be easily changed to a suitable member.
