Description

本発明は、人体から直接・間接に放射される輻射熱を利用して就寝時の体温を効果的に高める輻射熱利用寝具に関する。   The present invention relates to bedding using radiant heat that effectively increases body temperature at bedtime by using radiant heat radiated directly or indirectly from a human body.

就寝時に用いる寝具として、綿布団や羽毛布団などが一般的に用いられているものの、室温が低い冬期には十分な保温効果を得られない場合もある。そこで、ポリエステル布帛の表面にチタンをスパッタリング加工することにより、400Å程度のチタン膜を形成してなる寝具が提案されている(例えば、特許文献1を参照)。特許文献1に記載の寝具は、表面にチタンをスパッタリング加工した布帛の表面を使用者の身体側に置くようにすることで、エネルギーの吸収が大きく蓄熱性に優れたチタンの効果により、寝具の保温効果を高めることができる。   Although cotton duvets and duvets are generally used as bedclothes used at the time of going to bed, there may be cases where a sufficient heat retaining effect cannot be obtained in winter when the room temperature is low. Thus, a bedding has been proposed in which a titanium film of about 400 mm is formed by sputtering titanium on the surface of a polyester fabric (see, for example, Patent Document 1). The bedding described in Patent Document 1 is such that the surface of the fabric having titanium sputter-processed on the surface is placed on the user's body side. The heat retention effect can be enhanced.

また、遠赤外線の透過・吸収率が低く、反射率が高いというアルミ箔の特性を利用した保温シートを寝具に敷いて用いることが提案されている(例えば、特許文献2を参照)。特許文献2に記載の保温シートは、ポリエステル等のクッション性を有する断熱層のからだ側にアルミ箔シートで構成される遠赤外線反射シートを設けると共に、遠赤外線反射シートと断熱層には多数の通気孔を形成したものである。この通気孔を形成しておくことで、こもる湿気を外部に放出させ、就寝中や着用時に蒸し暑さを感じないようにすることができる。   In addition, it has been proposed to use a heat-insulating sheet using the characteristics of aluminum foil, which has a low far-infrared transmittance and absorption rate and a high reflectance, on a bedding (see, for example, Patent Document 2). The heat insulating sheet described in Patent Document 2 is provided with a far-infrared reflecting sheet composed of an aluminum foil sheet on the body side of a heat-insulating layer having cushioning properties such as polyester, and a large number of sheets are passed through the far-infrared reflecting sheet and the heat-insulating layer. A pore is formed. By forming this vent hole, it is possible to release the accumulated moisture to the outside so that it does not feel sultry while sleeping or wearing.

しかしながら、特許文献1に記載の寝具では、ポリエステル布帛の表面にチタン膜を形成するために、吸湿性あるいは排湿性が損なわれてしまい、湿気がこもって寝苦しくなる可能性が有る。よって、特許文献1に記載の寝具は、高い保温効果を実現できるとしても、吸湿性あるいは排湿性が損なわれるために湿気がこもり易く、必ずしも快適な睡眠を提供できる寝具とは言えない。   However, in the bedding described in Patent Document 1, since the titanium film is formed on the surface of the polyester fabric, the hygroscopicity or the moisture exhausting property is impaired, and there is a possibility that the moisture is accumulated and the bed becomes hard to sleep. Therefore, even if the bedding described in Patent Document 1 can achieve a high heat retention effect, it is not necessarily a bedding that can provide comfortable sleep because moisture absorption or moisture exhaustion is impaired and moisture is easily accumulated.

また、特許文献2に記載の保温シートの場合、十分な通気性を確保するためには、通気効果を得られる開口面積の通気孔を相当数設けておく必要があると考えられるが、通気孔を多数設けるということは、それだけ、遠赤外線反射シートにおけるアルミ箔の総面積が減ぜられることを意味する。そして、アルミ箔の総面積が少なくなれば、アルミ箔の特性による十分な保温効果を発揮できなくなるのである。すなわち、特許文献2に記載の保温シートでは、保温機能と除湿機能とがトレードオフの関係となるため、保温シート本来の保温性能を維持するためには、通気孔をあまり多くすることができず、こもる湿気を十分に外部に放出できない可能性がある。   In addition, in the case of the heat insulating sheet described in Patent Document 2, it is considered that in order to ensure sufficient air permeability, it is necessary to provide a considerable number of air holes having an opening area capable of obtaining a ventilation effect. Providing a large number means that the total area of the aluminum foil in the far-infrared reflecting sheet is reduced accordingly. If the total area of the aluminum foil is reduced, a sufficient heat retaining effect due to the characteristics of the aluminum foil cannot be exhibited. That is, in the heat insulating sheet described in Patent Document 2, since the heat insulating function and the dehumidifying function are in a trade-off relationship, in order to maintain the original heat insulating performance of the heat insulating sheet, it is not possible to increase the number of air holes. , It may not be possible to release sufficient moisture to the outside.

そこで、本発明は、人体から直接・間接に放射される輻射熱を利用して就寝時の体温を効果的に高めると共に、湿気がこもることを効果的に防げる輻射熱利用寝具の提供を目的とする。   Therefore, an object of the present invention is to provide a bedding using radiant heat that effectively increases body temperature at bedtime by using radiant heat radiated directly or indirectly from a human body and can effectively prevent moisture from being accumulated.

以下、本発明に係る輻射熱利用寝具の実施形態を添付図面に基づいて詳細に説明する。   Hereinafter, embodiments of a bedding utilizing radiant heat according to the present invention will be described in detail with reference to the accompanying drawings.

図1に示すのは、第1実施形態に係る輻射熱利用寝具1であり、遮熱シート2とシート保持体3により構成される。そして、この輻射熱利用寝具1は、横臥状態の人体(敷き布団の上に横たわった利用者)に直接当たるように上掛けするものではなく、人体と輻射熱利用寝具1との間に適宜な空間が生ずるように配置するものである。   FIG. 1 shows a bedding 1 using radiant heat according to the first embodiment, which includes a heat insulating sheet 2 and a sheet holder 3. The radiant heat utilizing bedding 1 is not overlaid so as to directly hit a lying human body (a user lying on a mattress), and an appropriate space is formed between the human body and the radiant heat utilizing bedding 1. Are arranged as follows.

上記遮熱シート2は、ゴム、ガラス、炭素或いはポリエステル等の化学繊維からなる可撓性シート基材21の少なくとも片面側へ、ポリエチレン等の溶着層22によって、アルミホイル等輻射熱に対して高反射率の素材からなる遮熱層23を熱融着したものである。また、可撓性シート基材21の他面側には、任意の印刷や焼き付け加工等を施したプリント層24を設けてあり、このプリント層24によって、室内環境にマッチした柄や模様等を付けておくことができる。この遮熱シート2においては、プリント層24側の装飾面2aが外向きとなり、遮熱層23側の遮熱面2bが内向き(横臥状態の人体側に向けて配置される状態)となるように使用する。   The heat shield sheet 2 is highly reflective to radiant heat such as aluminum foil by a welding layer 22 made of polyethylene or the like on at least one side of a flexible sheet base material 21 made of chemical fiber such as rubber, glass, carbon or polyester. The heat-shielding layer 23 made of a material having a high rate is heat-sealed. In addition, a print layer 24 subjected to arbitrary printing or baking is provided on the other surface side of the flexible sheet base material 21, and the print layer 24 allows a pattern or a pattern that matches the indoor environment to be provided. It can be attached. In this heat shield sheet 2, the decorative surface 2a on the printed layer 24 side faces outward, and the heat shield surface 2b on the heat shield layer 23 side faces inward (a state where the heat shield surface 2b is disposed toward the human body in a lying state). To use.

遮熱シート2における遮熱層23は、6〜12〔μm〕程度のアルミホイル等で構成可能であるから、遮熱シート2全体の厚みは0.2〔mm〕程度と非常に薄く作ることができ、遮熱シート2は非常に軽量化できる。そして、比較的大判(例えば、1.8〔m〕×1.8〔m〕の略正方形)となる遮熱シート2を折り畳んで小さくしたり筒状に丸めたりすれば取り扱い易くなるので、軽量化と相まって、遮熱シート2は可搬性に優れたものとなる。また、遮熱シート2にプリント層24を設ける必要が無い場合、可撓性シート基材21の両側に遮熱層23を設けておけば、遮熱シート2をリバーシブルで用いることが可能となる。さらに、遮熱シート2の四側縁部は剥き出しとせず、一定幅のテープ状の縁飾り等で四側縁部を覆っておけば、可撓性シート基材21から遮熱層23が剥離する等の不具合が生じることを抑制できる。   Since the heat shield layer 23 in the heat shield sheet 2 can be formed of aluminum foil or the like of about 6 to 12 [μm], the entire thickness of the heat shield sheet 2 should be made as thin as about 0.2 [mm]. Thus, the heat shield sheet 2 can be very light. And since it becomes easy to handle if the heat-shielding sheet 2 which becomes a comparatively large size (for example, an approximate square of 1.8 [m] × 1.8 [m]) is folded and rounded into a cylindrical shape, it is lightweight. Combined with this, the heat shield sheet 2 is excellent in portability. Further, when there is no need to provide the print layer 24 on the heat shield sheet 2, if the heat shield layer 23 is provided on both sides of the flexible sheet base material 21, the heat shield sheet 2 can be used reversibly. . Furthermore, if the four side edges of the heat shield sheet 2 are not exposed and are covered with a tape-shaped edge decoration or the like having a certain width, the heat shield layer 23 is peeled off from the flexible sheet base material 21. It is possible to suppress the occurrence of problems such as

一方、上記シート保持体3は、例えば、半円弧状の第1アーチ型骨材31A、第2アーチ型骨材31B、第3アーチ型骨材31C、第4アーチ型骨材31Dを、横臥状態の人体の頭部側(例えば、首付近)から足部(例えば、敷き布団よりも適宜外側となる位置)にかけてほぼ等距離間隔に配置したもので、第1〜第4アーチ型骨材31A〜31Dのアーチに跨がるように広げた遮熱シート2を被せると、遮熱シート2は半円筒状の形態に保持されることとなる。そして、半円筒状に保持された遮熱シート2の遮熱面2bと、横臥状態の人体との間には、頭部側開口4aから足部側開口4bにかけて連通する通気空部4が生ずる。このとき、適正位置に配置した遮熱シート2がシート保持体3からずれて大きな隙間が空いたり、シート保持体3から落ちたりしないように、適宜なシート固定手段(例えば、平板なマグネットシート等である着磁された固着板材32)を設けておくことが望ましい。   On the other hand, the sheet holding body 3 is, for example, a semicircular arc-shaped first arch-type aggregate 31A, second arch-type aggregate 31B, third arch-type aggregate 31C, and fourth arch-type aggregate 31D in a lying state. The first to fourth arch-shaped aggregates 31A to 31D are arranged at substantially equal intervals from the head side (for example, the vicinity of the neck) of the human body to the foot (for example, a position appropriately outside the mattress). When the thermal insulation sheet 2 spread over the arch is covered, the thermal insulation sheet 2 is held in a semi-cylindrical form. And between the heat-insulating surface 2b of the heat-insulating sheet 2 held in a semi-cylindrical shape and the human body in a lying state, a ventilation air space 4 communicating from the head-side opening 4a to the foot-side opening 4b is generated. . At this time, an appropriate sheet fixing means (for example, a flat magnet sheet or the like) is used so that the heat shield sheet 2 arranged at an appropriate position does not deviate from the sheet holder 3 to leave a large gap or fall from the sheet holder 3. It is desirable to provide a magnetized fixing plate material 32).

上記第1〜第4アーチ型骨材31A〜31Dは、軽量の中空パイプを複数連結して半円弧状にしたアーチ型パイプ311の両端部分に定置部312を設けた構造としてあり、アーチ型パイプ311が略鉛直面に沿った起立状態で、第1〜第4アーチ型骨材31A〜31Dを畳や床等の寝具設置面に定置することができる。このとき、第1〜第4アーチ型骨材31A〜31Dの配置間隔を一定にすると共に、第1〜第4アーチ型骨材31A〜31Dが倒れ難くするように、第1アーチ型骨材31Aの定置部312近傍と第2アーチ型骨材31Bの定置部312近傍を連結する第1連結部材33A、第2アーチ型骨材31Bの定置部312近傍と第3アーチ型骨材31Cの定置部312近傍を連結する第2連結部材33B、第3アーチ型骨材31Cの定置部312近傍と第4アーチ型骨材31Dの定置部312近傍を連結する第3連結部材33Cを用いても良い。そして、第1〜第3連結部材33A〜33Cを着脱可能にすると共に、第1〜第4アーチ型骨材31A〜31Dの各アーチ型パイプ311も複数の分割パーツに分離可能な構成としておけば、個々のパーツに分解することで、シート保持体3も持ち運びに適したものとなる。   The first to fourth arch type aggregates 31A to 31D have a structure in which stationary portions 312 are provided at both end portions of an arch type pipe 311 formed by connecting a plurality of lightweight hollow pipes into a semicircular arc shape. In a standing state along the substantially vertical plane 311, the first to fourth arched aggregates 31 </ b> A to 31 </ b> D can be placed on a bedding installation surface such as a tatami mat or a floor. At this time, the first arch type aggregates 31A to 31D are made constant, and the first arch type aggregates 31A to 31D are less likely to fall down, while the first arch type aggregates 31A to 31D are not easily collapsed. The first connecting member 33A for connecting the vicinity of the stationary portion 312 and the vicinity of the stationary portion 312 of the second arch-shaped aggregate 31B, the vicinity of the stationary portion 312 of the second arch-shaped aggregate 31B, and the stationary portion of the third arch-shaped aggregate 31C The second connecting member 33B that connects the vicinity of 312 and the third connecting member 33C that connects the vicinity of the stationary portion 312 of the third arched aggregate 31C and the vicinity of the stationary portion 312 of the fourth arched aggregate 31D may be used. The first to third connecting members 33A to 33C can be attached and detached, and the arch pipes 311 of the first to fourth arch type aggregates 31A to 31D can be separated into a plurality of divided parts. By disassembling into individual parts, the sheet holder 3 is also suitable for carrying.

また、第1〜第4アーチ型骨材31A〜31Dにおける各定置部312の少なくとも外側(敷き布団に向いていない側)には、平坦な強磁性面を設けてあり、この強磁性面と固着板材32との間に遮熱シート2を挟み込むようにすれば、遮熱シート2を固定することができ、固着板材32を取り外せば、遮熱シート2の固定を解除できる。なお、シート固定手段としては、固着板材32を用いるものに限らず、例えば、遮熱シート2の両サイドに適数設けた固着孔を、第1〜第4アーチ型骨材31A〜31Dそれぞれの定置部312に設けた固着突片に引っかけて固定する構造でも良いし、第1〜第4アーチ型骨材31A〜31Dそれぞれの定置部312に設けた鰐口クリップ等によって遮熱シート2の縁部を挟んで固定するような構造としても良い。   In addition, a flat ferromagnetic surface is provided on at least the outer side (the side not facing the mattress) of each stationary portion 312 in the first to fourth arch-shaped aggregates 31A to 31D. If the heat shield sheet 2 is sandwiched between the heat shield sheet 2, the heat shield sheet 2 can be fixed, and if the fixing plate member 32 is removed, the fixing of the heat shield sheet 2 can be released. Note that the sheet fixing means is not limited to the one using the fixing plate member 32, and, for example, fixing holes provided in appropriate numbers on both sides of the heat shield sheet 2 are provided for the first to fourth arch type aggregates 31A to 31D, respectively. It may have a structure that is fixed by hooking to a fixing protrusion provided on the stationary portion 312, or an edge portion of the heat shielding sheet 2 by a hook clip or the like provided on each stationary portion 312 of the first to fourth arch type aggregates 31 </ b> A to 31 </ b> D. It is good also as a structure fixed on both sides.

上述した第1実施形態に係る輻射熱利用寝具1は、敷き布団に寝た利用者の上側を覆うように配置して用いるが、人体と遮熱シート2の遮熱面2bとの間には適宜な空間である通気空部4が確保されているので、利用者が毛布や薄手の掛け布団などをかけて寝る場合でも、輻射熱利用寝具1が障害となることはない。そして、人体から直接放射される輻射熱あるいは人体によって暖まった毛布や掛け布団から間接放射される輻射熱は、半円筒状に配置された遮熱シート2の遮熱面2bに到達すると、この遮熱面2bにより大部分(例えば、97%)が反射されて人体側に戻るので(例えば、図1(c)を参照)、人体や毛布(あるいは掛け布団)に吸収されて熱となる。従って、人体や毛布等から輻射熱として失われた熱量が効率良く人体側に戻されるので、就寝時の体温を効果的に高めることができる。   Although the radiation heat utilization bedding 1 which concerns on 1st Embodiment mentioned above is arrange | positioned and used so that the upper side of the user who laid down on the mattress may be used, it is appropriate between the human body and the heat insulation surface 2b of the heat insulation sheet 2. Since the ventilation air space 4 that is a space is secured, even when a user sleeps on a blanket or a thin comforter, the radiant heat utilization bedding 1 does not become an obstacle. When the radiant heat radiated directly from the human body or the radiant heat indirectly radiated from the blanket or comforter warmed by the human body reaches the heat shield surface 2b of the heat shield sheet 2 arranged in a semi-cylindrical shape, the heat shield surface 2b. Most of (for example, 97%) is reflected and returns to the human body side (see, for example, FIG. 1C), and is absorbed by the human body or blanket (or comforter) and becomes heat. Accordingly, the amount of heat lost as radiant heat from the human body or blanket is efficiently returned to the human body side, so that the body temperature at bedtime can be effectively increased.

加えて、就寝時の発汗で人体から蒸散した湿気は、通気空部4内に溜まることとなるが、通気空部4は頭部側開口4aおよび足部側開口4bを介して外気と連通しているので、輻射熱利用寝具1を設置した部屋の室温よりも通気空部4内の温度が高まると、温度差による自然対流が生じて、通気空部4内の高温・高湿度の空気は低温低湿度の空気と入れ替わることとなる。すなわち、第1実施形態に係る輻射熱利用寝具1は、自然通気による除湿機能を発揮できるので、人体の回りに湿気がこもることを効果的に防ぎ、快適な睡眠を提供できる。しかも、湿気を含んだ暖かい空気は通気空部4内の高い位置に溜まってゆくので、人体よりも適宜離れた高い位置で気流が生じ易くなり、人体や毛布等の回りを包む暖気まで気流によって引き剥がされることを抑制できる。従って、輻射熱利用寝具1の利用者が自然通気によって寒い思いをすることも防げる。   In addition, moisture that has transpired from the human body due to sweating at bedtime accumulates in the ventilation space 4, and the ventilation space 4 communicates with the outside air through the head side opening 4a and the foot side opening 4b. Therefore, if the temperature in the ventilation space 4 rises above the room temperature of the room in which the radiant heat bedding 1 is installed, natural convection occurs due to the temperature difference, and the high-temperature and high-humidity air in the ventilation space 4 is low in temperature. It will be replaced with low-humidity air. That is, since the bedding 1 using radiant heat according to the first embodiment can exhibit a dehumidifying function by natural ventilation, it is possible to effectively prevent moisture from being accumulated around the human body and provide a comfortable sleep. Moreover, since warm air containing moisture accumulates at a high position in the ventilation space 4, airflow is likely to occur at a high position that is appropriately separated from the human body, and the warm air that wraps around the human body, blanket, etc. It can suppress that it is peeled off. Therefore, it is possible to prevent the user of the radiant heat utilizing bedding 1 from feeling cold due to natural ventilation.

なお、第1実施形態の輻射熱利用寝具1では、遮熱シート2を半円筒形状に保持できるシート保持体3を用いたが、これに限定されるものではなく、断面が略四角形状あるいは五角以上の多角形状とした半多角柱状に遮熱シート2を保持できるようなシート保持体を用いるようにしても良い。また、中空パイプのような軽量化素材ではなく、剛性の高い構造体により遮熱シート2を所要形状に保持することと併せて、地震等での落下物から人体を守れるような機能を付加しても良い。ただし、シート保持体3によって遮熱シート2を保持したときに形成される通気空部4が広くなり過ぎる(人体表面から遮熱シート2の遮熱面2bまでの距離が遠過ぎる)ようでは、遮熱シート2から人体側に戻せる輻射熱の量が減ってしまうし、逆に、通気空部4が狭過ぎる(人体表面から遮熱シート2の遮熱面2bまでの距離が近過ぎる)と、輻射熱利用寝具1の利用時に人が遮熱シート2の下に入ったり出たりすることが煩雑になる上、寝具利用者が就寝時に寝返りを打つことさえ困難になる可能性がある。すなわち、遮熱シート2の保持形状を決定するシート保持体3の構造は、輻射熱の効率的利用と寝具利用者の利便性を勘案して、通気空部4が好適なサイズ・形状となるように設定しておくことが望ましい。本実施形態に係る輻射熱利用寝具1のように、敷き布団の横幅程度を直径とする半円筒状に遮熱シート2を保持するサイズ・形状は理に適ったものである。   In the bedding 1 using radiant heat according to the first embodiment, the sheet holder 3 that can hold the heat shield sheet 2 in a semi-cylindrical shape is used. However, the present invention is not limited to this, and the cross section is substantially rectangular or five or more corners. You may make it use the sheet | seat holding body which can hold | maintain the heat insulation sheet 2 in the semi-polygonal column shape made into this polygonal shape. In addition to holding the heat shield sheet 2 in the required shape with a highly rigid structure rather than a lightweight material such as a hollow pipe, it also has a function to protect the human body from falling objects due to earthquakes, etc. May be. However, it seems that the ventilation space 4 formed when the heat shield sheet 2 is held by the sheet holder 3 is too wide (the distance from the human body surface to the heat shield surface 2b of the heat shield sheet 2 is too far) The amount of radiant heat that can be returned from the heat shield sheet 2 to the human body side is reduced, and conversely, the ventilation space 4 is too narrow (the distance from the human body surface to the heat shield surface 2b of the heat shield sheet 2 is too short), When using the radiant heat bedding 1, it becomes complicated for a person to enter or leave the heat shield sheet 2, and it may even be difficult for the bedding user to turn over at bedtime. That is, the structure of the sheet holding body 3 that determines the holding shape of the heat shield sheet 2 is such that the ventilation space 4 has a suitable size and shape in consideration of the efficient use of radiant heat and the convenience of the bedding user. It is desirable to set to. Like the bedding 1 using radiant heat according to the present embodiment, the size and shape for holding the heat shield sheet 2 in a semi-cylindrical shape having a diameter of about the width of the mattress is reasonable.

上記のように構成した第1実施形態の輻射熱利用寝具1は、一般家庭の寝室で使用できることは勿論、キャンプなどのアウトドアで使用したり、介護用ベッドを覆うように配置して用いたり、広い講堂など災害時の避難所で用いたりすることもできる。なお、第1実施形態に係る輻射熱利用寝具1は、ちょうど肩まで覆うような位置に遮熱シート2を配置する構造としたが、頭頂部まで完全に隠れるように遮熱シート2で覆う配置とし、就寝時のパーソナルスペースを遮熱シート2で完全に隠せるようにすると、災害時の避難所での利用に適したものとなる。   The radiant heat bedding 1 of the first embodiment configured as described above can be used in a bedroom of a general home, as well as used outdoors such as camping, or placed so as to cover a nursing bed, and is wide. It can also be used in evacuation shelters such as auditoriums. In addition, although the bedding 1 using radiant heat according to the first embodiment has a structure in which the heat shield sheet 2 is disposed at a position that covers just the shoulder, the heat shield sheet 2 is disposed so as to be completely hidden up to the top of the head. If the personal space at bedtime can be completely hidden by the heat shield sheet 2, it becomes suitable for use in an evacuation shelter during a disaster.

上述した第1実施形態の輻射熱利用寝具1は、好適な通気空部4を形成できるようにシート保持体3を用いて遮熱シート2の形状を保持できるようにしたものであるが、輻射熱利用寝具1を持ち運ぶ場合、遮熱シート2と併せてシート保持体3も運ばなければならず、シート保持体3を分離可能な軽量構造にしたとしても、やはり遮熱シート2の可搬性の高さには及ばない。そこで、シート保持体3を用いずに構成できる第2実施形態の輻射熱利用寝具について説明する。   The bedding 1 using radiant heat according to the first embodiment described above is configured such that the shape of the heat shield sheet 2 can be held using the sheet holding body 3 so that a suitable ventilation space 4 can be formed. When carrying the bedding 1, the sheet holder 3 must be carried together with the heat shield sheet 2, and even if the sheet holder 3 has a detachable lightweight structure, the heat shield sheet 2 is highly portable. Is not enough. Therefore, a radiant heat utilizing bedding according to a second embodiment that can be configured without using the sheet holder 3 will be described.

図2に示すのは、第2実施形態に係る輻射熱利用寝具1′であり、これは、一対の遮熱シート2′を用いて寝袋形状としたものである。遮熱シート2′は、上述した第1実施形態の輻射熱利用寝具1における遮熱シート2と同様に、プリント層24側である装飾面2aと遮熱層23側である遮熱面2bを備えるもので、その一側部(寝具利用時に頭部あるいは足部とならない二側部の一方)に雄型スナップボタン25を適数設け、他側部に雌型スナップボタン26を適数設けたものである。すなわち、一方の遮熱シート2′の雄型スナップボタン25と他方の遮熱シート2′の雌型スナップボタン26とが対向するように配置して各ボタンを閉じると、一対の遮熱シート2′の両側部を互いに連結することができ、寝袋形状となる。なお、一般的な寝袋は足部側を閉じて使うが、本実施形態に係る輻射熱利用寝具1′は、頭部側も足部側も開いており、寝具としての使用時には、どちらを頭側として使っても構わない。   FIG. 2 shows a bedding 1 ′ using radiant heat according to the second embodiment, which is formed into a sleeping bag shape using a pair of heat shield sheets 2 ′. The heat shield sheet 2 'includes a decorative surface 2a on the printed layer 24 side and a heat shield surface 2b on the heat shield layer 23 side, similarly to the heat shield sheet 2 in the radiant heat utilizing bedding 1 of the first embodiment described above. An appropriate number of male snap buttons 25 are provided on one side (one of the two sides not serving as a head or a foot when using bedding), and an appropriate number of female snap buttons 26 are provided on the other side. It is. That is, when the male snap button 25 of one heat shield sheet 2 'and the female snap button 26 of the other heat shield sheet 2' are arranged to face each other and each button is closed, the pair of heat shield sheets 2 Both sides of ′ can be connected to each other, and a sleeping bag shape is obtained. In addition, although a general sleeping bag is used with the foot side closed, the radiant heat bedding 1 'according to the present embodiment is open on both the head side and the foot side. You can use it as

輻射熱利用寝具1′の非使用時には、一対の遮熱シート2′がほぼ重なった平板状で、そのまま折り畳んだり丸めたりして、簡単に持ち運ぶことができる。無論、2枚の遮熱シート2′にバラして、個別に保管するようにしても構わない。また、輻射熱利用寝具1′を使用するときには、閉じられてない二側部の一方に頭を、他方に足を入れるように潜り込めば良い。このとき、人体の下側に配置される遮熱シート2′は、便宜上、下面遮熱シートとなり、人体の上側に配置される遮熱シート2′は、便宜上、上面遮熱シートとなる。なお、輻射熱利用寝具1′をアウトドア等で使う場合、下面遮熱シートは剥き出しの地面など冷たい凹凸面に接する可能性があるので、適宜なクッション性と断熱性を遮熱シート2′に付加できるよう、2〜5〔mm〕厚程度のウレタン素材を可撓性シート基材21として用いても良い。   When the radiant heat bedding 1 ′ is not in use, the pair of heat shield sheets 2 ′ are in the form of a flat plate that can be easily folded and rolled and carried easily. Of course, the two heat shield sheets 2 'may be separated and stored separately. Further, when using the radiant heat bedding 1 ′, it is only necessary to dive so that the head is put on one of the two sides not closed and the foot is put on the other. At this time, the heat shield sheet 2 ′ disposed below the human body is a lower surface heat shield sheet for convenience, and the heat shield sheet 2 ′ disposed above the human body is an upper surface heat shield sheet for convenience. In addition, when using the radiant heat bedding 1 'outdoors, the lower surface heat shield sheet may come in contact with a cold uneven surface such as the bare ground, so that appropriate cushioning and heat insulation can be added to the heat shield sheet 2'. As described above, a urethane material having a thickness of about 2 to 5 mm may be used as the flexible sheet base material 21.

上記のように構成した輻射熱利用寝具1′を利用するとき、アルミホイル等輻射熱に対して高反射率の素材からなる遮熱層23を備える遮熱シート2′は、毛布や掛け布団のように人体表面へ柔らかく纏わり付くようなことはなく、例えば、足先や胸元など、人体の突出した部分に当たって多少折れ曲がる程度であるから、その隙間として、頭部側開口4aから側部側開口4bにかけて連通する通気空部4が形成される。そして、この通気空部4により、輻射熱利用寝具1′の利用者が就寝時に発汗しても、内部に湿気が篭もって蒸し暑くなることを効果的に防げる。無論、遮熱シート2′の遮熱面2bにより人体側へ効率良く輻射熱を戻せるので、就寝時の体温を効果的に高める機能も発揮できる。   When using the radiant heat bedding 1 ′ configured as described above, the heat shield sheet 2 ′ including the heat shield layer 23 made of a material having high reflectivity with respect to radiant heat such as aluminum foil is used as a human body like a blanket or a comforter. There is no soft clinging to the surface. For example, it is slightly bent when hitting a protruding part of the human body such as a toe or a chest, so that the gap communicates from the head side opening 4a to the side opening 4b. A ventilation space 4 is formed. And even if the user of radiant heat utilization bedding 1 'sweats at the time of sleep by this ventilating space part 4, it can prevent effectively that moisture becomes moistened inside and becomes muddy. Of course, since the radiant heat can be efficiently returned to the human body side by the heat insulating surface 2b of the heat insulating sheet 2 ', the function of effectively increasing the body temperature at the time of sleeping can also be exhibited.

上述した輻射熱利用寝具1′は、上面遮熱シートおよび下面遮熱シートとして共通の遮熱シート2′を用いるものとしたが、これらを別々に構成しても良い。例えば、図2(c)に示す輻射熱利用寝具1″は、上面遮熱シート2−1と下面遮熱シート2−2の両側部を連結して寝袋形状とするものであるが、下面遮熱シート2−2の上縁側は上面遮熱シート2−1の上縁側よりも適宜長くなるように形成しておくことで、寝具利用者の頭部まで下面遮熱シート2−2を敷けるようにしたものである。また、上面遮熱シート2−1の両側部と下面遮熱シート2−2の両側部を連結する構造は別々に設けておくことができるので、連結構造の自由度を高めることができる。例えば、この輻射熱利用寝具1″においては、線ファスナー27によって上面遮熱シート2−1と下面遮熱シート2−2を着脱可能な構造とした。   The radiant heat bedding 1 'described above uses the common heat shield sheet 2' as the upper surface heat shield sheet and the lower surface heat shield sheet, but these may be configured separately. For example, the radiant heat bedding 1 ″ shown in FIG. 2 (c) has a sleeping bag shape by connecting both sides of the upper surface heat shield sheet 2-1 and the lower surface heat shield sheet 2-2. By forming the upper edge side of the sheet 2-2 to be appropriately longer than the upper edge side of the upper surface heat shield sheet 2-1, the lower heat shield sheet 2-2 can be laid down to the head of the bedding user. Moreover, since the structure which connects the both sides of the upper surface heat shielding sheet 2-1 and the both sides of the lower surface heat shielding sheet 2-2 can be provided separately, the degree of freedom of the connecting structure is increased. For example, in the bedding 1 ″ using radiant heat, the upper surface heat shield sheet 2-1 and the lower surface heat shield sheet 2-2 can be attached and detached by the wire fastener 27.

以上説明した輻射熱利用寝具1の遮熱シート2は、寝具として用いない場合、折り畳んだり丸めたりして、場所をとらずに収納しておくことができるものの、遮熱カバーとして有効利用することも可能である。例えば、図3に示すように、こたつ50のこたつ布団51と上掛け52との間に遮熱シート2をかけておくことで、遮熱カバーとして利用できる。また、遮熱シート2をこたつ敷き53の下側に敷く遮熱カバーとして利用できる。あるいは、フローリング面Fとカーペット60との間に複数枚の遮熱シート2を並べて敷けば、広い面に対応した遮熱カバーとして利用できる。   The heat shield sheet 2 of the bedding 1 using radiant heat described above can be folded or rolled up and stored without taking up space when not used as bedding, but it can also be effectively used as a heat shield cover. Is possible. For example, as shown in FIG. 3, the heat shield sheet 2 is placed between the kotatsu futon 51 and the upper cover 52 of the kotatsu 50, so that it can be used as a heat shield cover. Further, the heat shield sheet 2 can be used as a heat shield cover that is laid under the kotatsu lay 53. Alternatively, if a plurality of heat shield sheets 2 are arranged side by side between the flooring surface F and the carpet 60, they can be used as a heat shield cover corresponding to a wide surface.

次に、横臥状態の人体の下に敷いて用いる輻射熱利用寝具について説明する。   Next, a description will be given of a radiant heat bedding that is used under a lying human body.

図4に示すのは、第3実施形態に係る輻射熱利用寝具100であり、折り畳み可能なクッションマット状に構成したものである。すなわち、輻射熱利用寝具100は、嚢体たる収納体110を構成する第1収納部111a、第2収納部111b、第3収納部111c、第3収納部111dのそれぞれに扁平な略四角板状の遮熱体120を収納したものであり、第1〜第4収納部111a〜111dを一列状に広げて敷けば、寝具利用者が横たわれるクッションマットとなり、人体からの輻射熱を遮熱体120で反射させて人体側へ戻すのである。   FIG. 4 shows a bedding 100 using radiant heat according to the third embodiment, which is configured in a foldable cushion mat shape. In other words, the radiant heat utilizing bedding 100 has a substantially square plate shape that is flat in each of the first storage portion 111a, the second storage portion 111b, the third storage portion 111c, and the third storage portion 111d that constitute the storage body 110 that is a sac. The heat shield 120 is housed, and if the first to fourth storage portions 111a to 111d are laid out in a line, a cushion mat on which a bedding user lies is provided, and radiant heat from the human body is removed. It is reflected and returned to the human body.

上記遮熱体120は、例えばクッション性の高い発泡ウレタン等を可撓性シート基材121とし、その両面へ、ポリエチレン等の溶着層122によって、アルミホイル等輻射熱に対して高反射率の素材からなる遮熱層123を熱融着したものである。なお、輻射熱利用寝具100を一般的なシングルマットと同程度の200〔cm〕×100〔cm〕に形成する場合、各遮熱体120は50〔cm〕×100〔cm〕と大型になるが、各遮熱体120の厚みを5〜6〔mm〕程度にしておけば、輻射熱利用寝具100の持ち運びに負担を感じない程度の軽量化が可能である。また、遮熱体120は、両面に遮熱層120を設けてあるので、輻射熱利用寝具100のどちらの面を上側に使っても遮熱効果がある。   The heat shield 120 is made of, for example, urethane foam having a high cushioning property as a flexible sheet base material 121, and has a highly reflective material for radiant heat, such as aluminum foil, on both surfaces thereof by a weld layer 122 such as polyethylene. The heat shield layer 123 is heat-sealed. In addition, when the bedding 100 using radiant heat is formed to 200 [cm] × 100 [cm], which is similar to a general single mat, each heat shield 120 becomes large [50 [cm] × 100 [cm]. If the thickness of each heat shield 120 is set to about 5 to 6 [mm], the weight can be reduced to such an extent that a burden is not felt when carrying the radiant heat bedding 100. Moreover, since the heat shield 120 is provided with the heat shield layers 120 on both sides, the heat shield 120 has a heat shield effect regardless of which side of the radiant heat utilizing bedding 100 is used on the upper side.

上記収納体110は、例えば、布(薄い布でも、帆布のような厚手の生地でも良い)を縫い合わせて遮熱体120を収納できる内空状の第1〜第4収納部111a〜111dを作り、第1収納部111aと第2収納部111bを第1連結部112aにより連結し、第2収納部111bと第3収納部111cを第2連結部112bにより連結し、第3収納部111cと第4収納部111dを第3連結部112cにより連結したものである。このとき、第1連結部112aと第3連結部112cを同じ側(図4(a),(b)においては下面側)に設けると共に、第2連結部112bは反対側(図4(a),(b)においては上面側)に設けることで、第1〜第4収納部111a〜111dに収納された各遮熱体120を重ねるように折り畳むことができる(例えば、図4(d)を参照)。折り畳んだ状態の輻射熱利用寝具100は、椅子(例えば、座面の硬いベンチ130)等に敷くクッションとして使うこともできる。また、収納体110の外表面に防水加工を施しておくと、屋外での利用に適したものとなる。   The storage body 110 is made of, for example, first to fourth storage portions 111a to 111d that are hollow and can store the heat shield 120 by sewing cloth (thin cloth or thick cloth such as canvas). The first storage part 111a and the second storage part 111b are connected by the first connection part 112a, the second storage part 111b and the third storage part 111c are connected by the second connection part 112b, and the third storage part 111c and the second storage part 111c are connected. 4 storage parts 111d are connected by a third connecting part 112c. At this time, the first connecting portion 112a and the third connecting portion 112c are provided on the same side (the lower surface side in FIGS. 4A and 4B), and the second connecting portion 112b is on the opposite side (FIG. 4A). , (B) can be folded so that the respective heat shields 120 housed in the first to fourth housing portions 111a to 111d are stacked (for example, FIG. 4D). reference). The folded bedding 100 using radiant heat can also be used as a cushion laid on a chair (for example, a bench 130 with a hard seat). In addition, if the outer surface of the storage body 110 is waterproofed, it is suitable for outdoor use.

上述した第3実施形態に係る輻射熱利用寝具100は、広げると所要の大きさとなるので、そのまま寝具として使えるものの、折り畳んだ状態でもそれなりの大きさがあり、可搬性が高いとは言えない。そこで、ポケットサイズにすることで、可搬性を高められるようにした輻射熱利用寝具100′を図4(e),(f)に示す。   The radiant heat utilizing bedding 100 according to the third embodiment described above has a required size when it is spread out, so that it can be used as a bedding as it is, but it has a certain size even in a folded state and cannot be said to have high portability. 4 (e) and 4 (f) show a radiant heat bedding 100 'that can be made portable by improving the portability.

この輻射熱利用寝具100′も、嚢体たる収納体110′を構成する第1収納部111a、第2収納部111b、第3収納部111c、第3収納部111dのそれぞれに扁平な略四角板状の遮熱体120を収納したものであり、例えば、第1収納部111aと第2,第4収納部111b,111dが隣接するように第1〜第4収納部111a〜111dを田の字状に広げると(例えば、図4(e)を参照)、寝具利用者の下側に敷くことができる大きさ(例えば、一辺が20〔cm〕〜30〔cm〕の略四角形状)のクッションマットとなり、人体からの輻射熱を遮熱体120で反射させて人体側へ戻すのである。   This radiant heat bedding 100 'also has a substantially rectangular plate shape that is flat in each of the first storage portion 111a, the second storage portion 111b, the third storage portion 111c, and the third storage portion 111d constituting the storage body 110' that is a sac. For example, the first to fourth storage portions 111a to 111d are shaped like a rice pad so that the first storage portion 111a and the second and fourth storage portions 111b and 111d are adjacent to each other. (For example, see FIG. 4 (e)), the cushion mat has a size that can be laid on the underside of the bedding user (for example, a substantially square shape with sides of 20 cm to 30 cm). Thus, the radiant heat from the human body is reflected by the heat shield 120 and returned to the human body side.

上記収納体110′は、例えば、防水性のある素材(例えば、ポリ塩化ビニル等の樹脂素材や防水処理を施した布等)で遮熱体120を収納できる内空状の第1〜第4収納部111a〜111dを作り、第1収納部111aと第2収納部111bを第1連結部112aにより連結し、第2収納部111bと第3収納部111cを第2連結部112bにより連結し、第3収納部111cと第4収納部111dを第3連結部112cにより連結したものである。なお、第1収納部111aと第4収納部111dは連結していないので、面ファスナーなどの固定手段で第1収納部111aと第4収納部111dを連結し、第1〜第4収納部111a〜111dが田の字状に保持されるようにしても良い。   The storage body 110 ′ is, for example, a hollow first to fourth space that can store the heat shield 120 with a waterproof material (for example, a resin material such as polyvinyl chloride or a waterproof cloth). The storage portions 111a to 111d are made, the first storage portion 111a and the second storage portion 111b are connected by the first connection portion 112a, the second storage portion 111b and the third storage portion 111c are connected by the second connection portion 112b, The third storage part 111c and the fourth storage part 111d are connected by a third connection part 112c. In addition, since the 1st accommodating part 111a and the 4th accommodating part 111d are not connected, the 1st accommodating part 111a and the 4th accommodating part 111d are connected by fixing means, such as a hook-and-loop fastener, and the 1st-4th accommodating part 111a is connected. ˜111d may be held in a square shape.

上記収納体110′における第1連結部112aと第3連結部112cを同じ側(図4(e)においては上面側)に設けると共に、第2連結部112bは反対側(図4(e)においては下面側)に設けることで、第1〜第4収納部111a〜111dに収納された各遮熱体120を重ねるように折り畳むことができる(例えば、図4(f)を参照)。なお、第1〜第4収納部111a〜111dの折り畳み手法はこれに限らず、例えば、ハンカチを折り畳むように縦折りと横折りで畳めるようにしても良い。これら第1〜第4収納部111a〜111dは、それぞれ一辺が概ね10〔cm〕〜15〔cm〕程度で、厚さが5〜6〔mm〕程度の遮熱体120を収納してあるので、折り畳むと、ハンドバッグや上着のポケット等に入るコンパクトサイズとなる。   The first connecting portion 112a and the third connecting portion 112c in the storage body 110 ′ are provided on the same side (the upper surface side in FIG. 4E), and the second connecting portion 112b is on the opposite side (in FIG. 4E). Is provided on the lower surface side, so that the heat shields 120 accommodated in the first to fourth accommodating portions 111a to 111d can be folded so as to overlap (see, for example, FIG. 4F). In addition, the folding method of the 1st-4th accommodating parts 111a-111d is not restricted to this, For example, you may make it fold by vertical folding and horizontal folding so that a handkerchief may be folded. Each of the first to fourth storage portions 111a to 111d stores a heat shield 120 having a side of about 10 cm to 15 cm and a thickness of about 5 to 6 mm. When folded, it becomes a compact size that fits into a handbag or a jacket pocket.

そして、田の字状に広げた輻射熱利用寝具100′を複数用意しておき、面ファスナー等の連結手段によって複数の輻射熱利用寝具100′を縦横に適宜連結すれば、人体が横たわれる大きさにして使うことができる。なお、輻射熱利用寝具100′単体でも、腰・背中・肩・足下などの必要部位にのみ敷いて用いることができるし、硬い座面などに敷くクッションとしても用いることができる。また、輻射熱利用寝具100′の収納体110′は防水性が高いので、輻射熱利用寝具100′を湿った地面などに敷いて使うことができ、アウトドアでの利用に適している。   Then, by preparing a plurality of radiant heat bedding 100 'spread in a rice field shape and connecting the plurality of radiant heat bedding 100' vertically and horizontally by a connecting means such as a hook-and-loop fastener, the size of the human body is laid down. Can be used. The radiant heat bedding 100 'alone can be used only on necessary parts such as the waist, back, shoulders, and feet, or can be used as a cushion on a hard seat. Further, since the housing 110 ′ of the radiant heat bedding 100 ′ is highly waterproof, the radiant heat bedding 100 ′ can be laid on a damp ground or the like and is suitable for outdoor use.

図5に示すのは、膨縮可能なエアマット状に構成した第4実施形態に係る輻射熱利用寝具200であり、空気を入れて膨らませたり空気を抜いて平坦な状態に戻したりできる収納体210の内部に複数の遮熱体220を収納したものである。   FIG. 5 shows a radiant heat bedding 200 according to the fourth embodiment configured in an inflatable / deflateable air mat shape, and includes a storage body 210 that can be inflated by inflating or returning to a flat state by extracting air. A plurality of heat shields 220 are housed inside.

上記収納体210は、機密性の高い素材(例えば、軟質PVC樹脂など)でできた略長方形の第1気密シート211と第2気密シート212を重ねて、四側縁部を密着(例えば、熱融着)させた辺縁密着部213を形成すると共に、収納体210の長手方向(以下、これを縦方向という)に第1縦密着部214aと第2縦密着部214bと第3縦密着部214cと第4縦密着部214dを不連続で形成し、第1縦密着部214aと第2縦密着部214bとの間の短手方向(以下、これを横方向という)に第1横密着部215aと第2横密着部215bを不連続で形成し、第2縦密着部214bと第3縦密着部214cとの間の横方向に第3横密着部215cと第4横密着部215dを不連続で形成し、第3縦密着部214cと第4縦密着部214dとの間の横方向に第5横密着部215eと第6横密着部215fを不連続で形成する。   The container 210 is formed by stacking a substantially rectangular first airtight sheet 211 and a second airtight sheet 212 made of a highly confidential material (for example, soft PVC resin), and closely contacting the four side edges (for example, heat The edge contact portion 213 fused) is formed, and the first vertical contact portion 214a, the second vertical contact portion 214b, and the third vertical contact portion are arranged in the longitudinal direction of the storage body 210 (hereinafter referred to as the vertical direction). 214c and the fourth vertical contact portion 214d are formed discontinuously, and the first horizontal contact portion is formed in a short direction (hereinafter referred to as a horizontal direction) between the first vertical contact portion 214a and the second vertical contact portion 214b. 215a and the second lateral contact portion 215b are formed discontinuously, and the third lateral contact portion 215c and the fourth lateral contact portion 215d are not horizontally disposed between the second vertical contact portion 214b and the third vertical contact portion 214c. The third vertical contact portion 214c and the fourth vertical contact portion 2 are formed continuously. A fifth horizontal contact portion 215e and the sixth horizontal contact portion 215f formed discontinuously in the transverse direction between the 4d.

上記のように各種密着部を形成した収納体210には、略四角形で平板状の遮熱体220をそれぞれ収納できる8つの領域が形成される。具体的には、辺縁密着部213と第1縦密着部214aと第1横密着部215aとで囲まれた第1収納領域216a、辺縁密着部213と第1横密着部215aと第2縦密着部214bと第3横密着部215cとで囲まれた第2収納領域216b、辺縁密着部213と第3横密着部215cと第3縦密着部214cと第5横密着部215eとで囲まれた第3収納領域216c、辺縁密着部213と第5横密着部215eと第4縦密着部214dとで囲まれた第4収納領域216d、辺縁密着部213と第1縦密着部214aと第2横密着部215bとで囲まれた第4収納領域216e、辺縁密着部213と第2横密着部215bと第2縦密着部214bと第4横密着部215dとで囲まれた第6収納領域216f、辺縁密着部213と第4横密着部215dと第3縦密着部214cと第6横密着部215fとで囲まれた第7収納領域216g、辺縁密着部213と第6横密着部215fと第4縦密着部214dとで囲まれた第8収納領域216hである。   As described above, the storage body 210 in which the various contact portions are formed is formed with eight regions that can each store the substantially rectangular and flat plate heat shield 220. Specifically, the first storage area 216a surrounded by the edge contact portion 213, the first vertical contact portion 214a, and the first horizontal contact portion 215a, the edge contact portion 213, the first horizontal contact portion 215a, and the second. The second storage region 216b surrounded by the vertical contact portion 214b and the third horizontal contact portion 215c, the edge contact portion 213, the third horizontal contact portion 215c, the third vertical contact portion 214c, and the fifth horizontal contact portion 215e. The fourth storage region 216d, the edge contact portion 213, and the first vertical contact portion surrounded by the surrounded third storage region 216c, the edge contact portion 213, the fifth horizontal contact portion 215e, and the fourth vertical contact portion 214d. 214a and second lateral contact portion 215b surrounded by a fourth storage area 216e, an edge contact portion 213, a second lateral contact portion 215b, a second vertical contact portion 214b, and a fourth lateral contact portion 215d. Sixth storage area 216f, edge contact portion 213 and fourth side Surrounded by the seventh storage area 216g surrounded by the attachment portion 215d, the third vertical contact portion 214c, and the sixth horizontal contact portion 215f, the edge contact portion 213, the sixth horizontal contact portion 215f, and the fourth vertical contact portion 214d. This is the eighth storage area 216h.

上記収納体210に形成した第1〜第8収納領域216a〜216hは、完全には区画されておらず、各密着部の間に生じた空隙を介して連通しているので、吸排気部217から収納体210内に空気を入れると、第1〜第8収納領域216a〜216hの全領域を膨らませることができる。   The first to eighth storage regions 216a to 216h formed in the storage body 210 are not completely partitioned and communicate with each other through a gap formed between the close contact portions. When the air is put into the storage body 210 from the top, the entire area of the first to eighth storage areas 216a to 216h can be inflated.

上記遮熱体220は、例えば、四つ角を弧状に面取りした略四角形状の平板な遮熱シート221と、遮熱シート221の四側縁を囲む額縁状に形成された縁部ガード体222から成る。遮熱シート221は、不織布等からなる可撓性シート基材221aの両面にアルミホイル等輻射熱に対して高反射率の素材からなる遮熱層221bを形成したもので、0.2〔mm〕程度の厚さである。縁部ガード体222は、収納体210の内部を傷つけるような先鋭部が生じないように、外側面が半円弧状となる弧状摺動面222aとする。なお、遮熱体220が収納体210内を低摩擦で摺動できるようにするため、縁部ガード体222を低摩擦の素材(例えば、ポリアセタール、ポリアミド、ポリテトラフルオロエチレン等)で形成するか、あるいは弧状摺動面222aを低摩擦材料でコーティングする。また、各遮熱体220は、空気を抜いた収納体210における第1〜第8収納領域216a〜216hよりも一回り小さいが(図5(a)を参照)、収納体210内に空気を入れて第1〜第8収納領域216a〜216hが膨らんだときには、各領域を区画する各密着部の間にちょうど収まる大きさである(図5(b),(c)を参照)。   The heat shield 220 includes, for example, a substantially rectangular flat plate heat shield sheet 221 whose four corners are chamfered in an arc shape, and an edge guard body 222 formed in a frame shape surrounding the four side edges of the heat shield sheet 221. . The heat shielding sheet 221 is formed by forming a heat shielding layer 221b made of a material having high reflectivity with respect to radiant heat such as aluminum foil on both surfaces of a flexible sheet base material 221a made of a nonwoven fabric or the like, and has a thickness of 0.2 [mm]. It is about the thickness. The edge guard body 222 is an arcuate sliding surface 222a whose outer surface is a semicircular arc so that a sharpened portion that damages the inside of the storage body 210 does not occur. Whether the edge guard body 222 is formed of a low friction material (for example, polyacetal, polyamide, polytetrafluoroethylene, etc.) so that the heat shield 220 can slide in the storage body 210 with low friction. Alternatively, the arcuate sliding surface 222a is coated with a low friction material. Further, each heat shield 220 is slightly smaller than the first to eighth storage areas 216a to 216h in the storage body 210 from which air has been removed (see FIG. 5A), but air is introduced into the storage body 210. When the first to eighth storage areas 216a to 216h are inflated, the size of the first storage area 216a to 216h just fits between the close contact portions that define each area (see FIGS. 5B and 5C).

上記のように構成した輻射熱利用寝具200は、不使用時に第1縦密着部214a〜第4縦密着部214dおよび第1横密着部215a〜第8横密着部215fに沿って折り畳むことで、ほぼ遮熱体220の大きさにして収納することができる。また、遮熱シート220も極めて薄く形成してあるので、折り畳んだ輻射熱利用寝具200全体の厚みも非常に薄くでき、可搬性に優れたものとなる。   The radiant heat utilizing bedding 200 configured as described above is folded substantially along the first vertical contact portion 214a to the fourth vertical contact portion 214d and the first horizontal contact portion 215a to the eighth horizontal contact portion 215f when not in use. The heat shield 220 can be stored in a size. Moreover, since the heat shielding sheet 220 is also formed extremely thin, the thickness of the folded bedding 200 using radiant heat can be made very thin, and the portability is excellent.

一方、輻射熱利用寝具200を使用するときには、吸排気部217から収納体210内へ給気することで、第1〜第8収納領域216a〜216hを均等に膨らませる。このとき、第1気密シート211と第2気密シート212は内部に空気が入ることで上下方向へ互いに離れ、その分だけ縦横が縮んでゆくこととなり、第1〜第8収納領域216a〜216hの各領域もそれぞれ縦横に縮んでゆく。このとき、第1〜第8収納領域216a〜216h内に収納されている各遮熱体220は、第1〜第8収納領域216a〜216hの収縮に追随して収縮することはないが、第1〜第8収納領域216a〜216h内で自由に動けるので、遮熱体220が置かれている底部が縦横に縮んだら、縦横方向に広い空間のある上方へと移動する。特に、遮熱体220の縁部ガード体222には弧状摺動面222aを形成してあるので、遮熱体220が第1〜第8収納領域216a〜216hの内面に引っかかって動かなくなるような不具合は生じ難く、膨張時に縦横が最も広い状態となっている各密着部が位置する平面上(第1〜第8収納領域216a〜216hにおける上下方向のほぼ中央:図5(c)を参照)に収まることとなる。   On the other hand, when using the radiant heat bedding 200, the first to eighth storage areas 216a to 216h are evenly expanded by supplying air from the intake / exhaust part 217 into the storage body 210. At this time, the first hermetic sheet 211 and the second hermetic sheet 212 are separated from each other in the vertical direction by entering air therein, and the vertical and horizontal directions are contracted accordingly, and the first to eighth storage areas 216a to 216h Each area shrinks vertically and horizontally. At this time, each heat shield 220 accommodated in the first to eighth storage areas 216a to 216h does not contract following the contraction of the first to eighth storage areas 216a to 216h. Since it can move freely within the first to eighth storage areas 216a to 216h, when the bottom part on which the heat shield 220 is placed contracts vertically and horizontally, it moves upward with a wide space in the longitudinal and lateral directions. In particular, since the edge guard body 222 of the heat shield 220 is formed with an arcuate sliding surface 222a, the heat shield 220 is caught by the inner surfaces of the first to eighth storage areas 216a to 216h and cannot move. On the plane where the close contact portions that are in a state where the vertical and horizontal directions are the widest when expanded are located (almost center in the vertical direction in the first to eighth storage regions 216a to 216h: see FIG. 5C) Will fit in.

したがって、第1〜第8収納領域216a〜216hを膨らませたとき、遮熱体220と第1気密シート211との間に生じる上側空気貯留部218aと、遮熱体220と第2気密シート212との間に生じる下側空気貯留部218bとが、ほぼ均等となり、第1気密シート211を下向きにして使っても、第2気密シート212を下向きにして使っても、輻射熱利用寝具200上に横たわった人体からの輻射熱を遮熱体220で反射させて人体側へ戻すことができる。   Accordingly, when the first to eighth storage regions 216a to 216h are inflated, the upper air storage portion 218a generated between the heat shield 220 and the first airtight sheet 211, the heat shield 220 and the second airtight sheet 212, The lower air storage portion 218b generated between the first air-tight sheet 211 and the second air-tight sheet 212 faces downward, and lies on the radiant heat bedding 200. The radiant heat from the human body can be reflected by the heat shield 220 and returned to the human body side.

上述した第4実施形態に係る輻射熱利用寝具200は、上下リバーシブルで使用できる反面、遮熱体220に縁部ガード体222を設ける必要があるために高コストになってしまう。そこで、低コストで製造できる膨縮可能なエアマット状に構成した輻射熱利用寝具を、図6に示す第5実施形態に基づき説明する。   The bedding 200 using radiant heat according to the fourth embodiment described above can be used in an up-and-down reversible manner. However, since the edge guard body 222 needs to be provided on the heat shield 220, the cost increases. Therefore, a radiant heat bedding configured in an inflatable / deflatable air mat shape that can be manufactured at low cost will be described based on a fifth embodiment shown in FIG.

第5実施形態に係る輻射熱利用寝具300は、空気を入れて膨らませたり、空気を抜いて平坦な状態に戻したりできる収納体310の内部に複数の遮熱体320を収納したものである。   The bedding 300 using radiant heat according to the fifth embodiment is one in which a plurality of heat shields 320 are housed in a housing 310 that can be inflated with air or can be deflated and returned to a flat state.

上記収納体310は、機密性の高い素材(例えば、軟質PVC樹脂など)でできた略長方形で8つの膨出領域が形成された第1気密シート311と、略長方形で平坦な第2気密シート312を重ねて、四側縁部を密着(例えば、熱融着)させた辺縁密着部313を形成すると共に、収納体310の長手方向(以下、これを縦方向という)に第1縦密着部314aと第2縦密着部314bと第3縦密着部314cと第4縦密着部314dを不連続で形成し、第1縦密着部314aと第2縦密着部314bとの間の短手方向(以下、これを横方向という)に第1横密着部315aと第2横密着部315bを不連続で形成し、第2縦密着部314bと第3縦密着部314cとの間の横方向に第3横密着部315cと第4横密着部315dを不連続で形成し、第3縦密着部314cと第4縦密着部314dとの間の横方向に第5横密着部315eと第6横密着部315fを不連続で形成する。   The storage body 310 includes a first airtight sheet 311 formed of a material having high confidentiality (for example, soft PVC resin) and having eight bulged areas, and a second airtight sheet that is substantially rectangular and flat. 312 is overlapped to form the edge contact portion 313 in which the four side edges are closely contacted (for example, heat-sealed), and the first longitudinal contact in the longitudinal direction of the storage body 310 (hereinafter referred to as the longitudinal direction). The portion 314a, the second vertical contact portion 314b, the third vertical contact portion 314c, and the fourth vertical contact portion 314d are discontinuously formed, and the short direction between the first vertical contact portion 314a and the second vertical contact portion 314b is formed. The first lateral contact portion 315a and the second lateral contact portion 315b are formed discontinuously in the horizontal direction (hereinafter, referred to as a lateral direction), and the lateral direction between the second vertical contact portion 314b and the third vertical contact portion 314c is formed. The third lateral contact portion 315c and the fourth lateral contact portion 315d are discontinuous. Form, to form a fifth lateral contact portion 315e and the sixth horizontal contact portion 315f in discontinuous in the transverse direction between the third vertical contact portion 314c and the fourth vertical contact portion 314d.

上記のように各種密着部を形成した収納体310は、第1気密シート311に形成した8つの膨出領域が各密着部で区画される。具体的には、辺縁密着部313と第1縦密着部314aと第1横密着部315aとで囲まれた第1膨出領域316a、辺縁密着部313と第1横密着部315aと第2縦密着部314bと第3横密着部315cとで囲まれた第2膨出領域316b、辺縁密着部313と第3横密着部315cと第3縦密着部314cと第5横密着部315eとで囲まれた第3膨出領域316c、辺縁密着部313と第5横密着部315eと第4縦密着部314dとで囲まれた第4膨出領域316d、辺縁密着部313と第1縦密着部314aと第2横密着部315bとで囲まれた第4膨出領域316e、辺縁密着部313と第2横密着部315bと第2縦密着部314bと第4横密着部315dとで囲まれた第6膨出領域316f、辺縁密着部313と第4横密着部315dと第3縦密着部314cと第6横密着部315fとで囲まれた第7膨出領域316g、辺縁密着部313と第6横密着部315fと第4縦密着部314dとで囲まれた第8膨出領域316hである。   As described above, the storage body 310 in which various contact portions are formed has eight bulging regions formed in the first airtight sheet 311 defined by the respective contact portions. Specifically, the first bulging region 316a surrounded by the edge contact portion 313, the first vertical contact portion 314a, and the first horizontal contact portion 315a, the edge contact portion 313, the first horizontal contact portion 315a, and the first. The second bulging region 316b surrounded by the two vertical contact portions 314b and the third horizontal contact portion 315c, the edge contact portion 313, the third horizontal contact portion 315c, the third vertical contact portion 314c, and the fifth horizontal contact portion 315e. The third bulging region 316d surrounded by the fourth bulging region 316d, the marginal close contact portion 313d, the fourth lateral close contact portion 315e, and the fourth vertical close contact portion 314d. The fourth bulging region 316e surrounded by the first vertical contact portion 314a and the second horizontal contact portion 315b, the edge contact portion 313, the second horizontal contact portion 315b, the second vertical contact portion 314b, and the fourth horizontal contact portion 315d. The sixth bulging region 316f, the edge contact portion 313 and the fourth side The seventh bulging region 316g surrounded by the attachment portion 315d, the third vertical contact portion 314c, and the sixth horizontal contact portion 315f, the edge contact portion 313, the sixth horizontal contact portion 315f, and the fourth vertical contact portion 314d. It is the 8th bulging area | region 316h enclosed.

上記収納体310に設けた第1〜第8膨出領域316a〜216hは、必要十分な空気が封入されて膨らんでいるとき、何れも扁平な四角錘台形状であり、錘台の上底となる平坦面に寝具利用者が横たわることができる(図6(b)を参照)。一方、第1〜第8膨出領域316a〜216hにおける錘台の下底となる平坦面(第1〜第8膨出領域316a〜216hにそれぞれ対応する第2気密シート312の内面)には、それぞれ略四角形状の遮熱体320を設ける。   The first to eighth bulging regions 316a to 216h provided in the storage body 310 are flat square frustum shapes when necessary and sufficient air is filled and swollen, The bedding user can lie on the flat surface (see FIG. 6B). On the other hand, on the flat surface (the inner surface of the second hermetic sheet 312 corresponding to each of the first to eighth bulging regions 316a to 216h) in the first to eighth bulging regions 316a to 216h, which is the lower bottom of the frustum, A substantially quadrangular heat shield 320 is provided.

上記遮熱体320は、第1〜第8膨出領域316a〜216hに対応する第2気密シート312の内面(図6(b)〜(d)においては上面)に、アルミホイル等の遮熱シート321をそれぞれ貼着することで構成したが、この構成に限らない。例えば、不織布や樹脂フィルムをシート基材として片面にアルミホイル等輻射熱に対して高反射率の素材からなる遮熱層を形成することで遮熱体を構成し、遮熱層が外表面となるように第2気密シート312の内面にそれぞれ取り付けるようにしても良い。何れにしても、遮熱体320は廉価に設けることができ、遮熱体利用寝具300のコストを低減できる。   The heat shield 320 has a heat shield such as an aluminum foil on the inner surface (the upper surface in FIGS. 6B to 6D) of the second hermetic sheet 312 corresponding to the first to eighth bulging regions 316a to 216h. Although it comprised by sticking each sheet | seat 321, it is not restricted to this structure. For example, a non-woven fabric or a resin film is used as a sheet base material to form a heat shield by forming a heat shield layer made of a material having high reflectivity against radiant heat such as aluminum foil on one side, and the heat shield layer becomes the outer surface. In this manner, each of the second airtight sheets 312 may be attached to the inner surface. In any case, the heat shield 320 can be provided at a low price, and the cost of the heat shield bedding 300 can be reduced.

上記のように構成した輻射熱利用寝具300を使用するとき、吸排気部317から収納体310内へ給気する。これにより、第1〜第8収納領域216a〜216h本来の扁平な四角錘台形状が保持され、エアクッションとして機能する(図6(c)を参照)。また、輻射熱利用寝具300上に横たわった人体からの輻射熱を遮熱体320で反射させて人体側へ戻すことができる。   When the bedding 300 using radiant heat configured as described above is used, air is supplied from the intake / exhaust portion 317 into the housing 310. Thereby, the original flat square frustum shape of the first to eighth storage areas 216a to 216h is maintained, and functions as an air cushion (see FIG. 6C). Further, the radiant heat from the human body lying on the radiant heat utilizing bedding 300 can be reflected by the heat shield 320 and returned to the human body side.

また、輻射熱利用寝具300を使用しないときは、収納体310内から空気を抜く。これにより、第1気密シート311の膨出部が自重で潰れて、第1〜第8膨出領域316a〜216h本来の扁平な四角錘台形状が維持できなくなり、第2気密シート312上へ重なるようにしぼむので、第1気密シート311側も平坦に近い薄さとなる(図6(d)を参照)。よって、輻射熱利用寝具300を各密着部に沿って折り畳むと、嵩張らない大きさとなり、収納に適したものとなる。   Further, when the radiant heat bedding 300 is not used, the air is extracted from the storage body 310. As a result, the bulging portion of the first airtight sheet 311 is crushed by its own weight, and the original flat square frustum shape cannot be maintained, and the first airtight sheet 311 overlaps the second airtight sheet 312. Therefore, the first airtight sheet 311 side is also almost flat (see FIG. 6D). Therefore, when the bedding 300 using the radiant heat is folded along each contact portion, the size becomes not bulky and is suitable for storage.
