Japanese Utility Model Publication No. 3-39021

ところで、前記保冷機能付き枕では、袋部材上に頭部が載置され、頭部近傍の潜熱蓄熱材に熱が伝わると、潜熱蓄熱材が相変化する所定温度に維持され、頭部を保冷するようになっている。 By the way, in the pillow with the cold insulation function, when the head is placed on the bag member and heat is transferred to the latent heat storage material in the vicinity of the head, the latent heat storage material is maintained at a predetermined temperature at which the phase changes, and the head is cooled. It is supposed to be.

しかしながら、相変化を利用した潜熱蓄熱材は金属等のように熱伝導性に優れた材料ではないので、載置された頭部が動かない場合は、頭部近傍の潜熱蓄熱材のみが相変化し、その他の部分の潜熱蓄熱材には熱が伝わり難いので、袋部材内の潜熱蓄熱材の潜熱を効率良く利用することができず、頭部の保冷効果を長時間に亘って維持することができないという問題点があった。 However, the latent heat storage material using phase change is not a material with excellent thermal conductivity such as metal, so if the mounted head does not move, only the latent heat storage material near the head will undergo phase change. However, since it is difficult for heat to be transmitted to other parts of the latent heat storage material, the latent heat of the latent heat storage material in the bag member cannot be used efficiently, and the head cooling effect is maintained for a long time. There was a problem that could not.

本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、載置された頭部が動かない場合でも、頭部の保冷効果を長時間に亘って維持することのできる保冷機能付き枕を提供することにある。 The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to maintain the head cooling effect for a long time even when the placed head does not move.

これにより、枕本体の上面側に保冷部材を設けていることから、枕本体の上面側に頭部が載置されると、頭部近傍の保冷部材に熱が伝わる。また、保冷部材に金属繊維群を設けたことから、頭部近傍の保冷部材に伝わった熱が金属繊維群を介して保冷部材における広い範囲に伝わる。さらに、保冷部材に金属繊維群の各金属繊維同士の隙間に入り込むように設けられた潜熱蓄熱材を設けたことから、保冷部材における広い範囲において金属繊維群から潜熱蓄熱材に効率良く熱が伝わる。 Thereby, since the cold insulation member is provided on the upper surface side of the pillow body, when the head is placed on the upper surface side of the pillow body, heat is transmitted to the cold insulation member near the head. In addition, since the metal fiber group is provided on the cold insulation member, the heat transmitted to the cold insulation member near the head is transmitted to a wide range in the cold insulation member via the metal fiber group. Further, since the latent heat storage material provided so as to enter the gap between the metal fibers of the metal fiber group is provided in the cold insulation member, heat is efficiently transmitted from the metal fiber group to the latent heat storage material in a wide range of the cold insulation member. .

また、本発明の保冷機能付き枕は、使用者の頭部を支持する枕本体と、枕本体の上面側に設けられた保冷部材とを備え、前記保冷部材に、金属製網状部材と、金属製網状部材の隙間に入り込むように設けられるとともに相変化に伴う潜熱を利用して蓄熱可能な潜熱蓄熱材とを設けている。 Moreover, the pillow with a cold insulation function of the present invention includes a pillow body that supports the user's head, and a cold insulation member provided on the upper surface side of the pillow body, and the cold insulation member includes a metal mesh member and a metal There is provided a latent heat storage material that is provided so as to enter the gap between the net-like members and that can store heat by using latent heat accompanying phase change.

これにより、枕本体の上面側に保冷部材を設けていることから、枕本体の上面側に頭部が載置されると、頭部近傍の保冷部材に熱が伝わる。また、保冷部材に金属製網状部材を設けたことから、頭部近傍の保冷部材に伝わった熱が金属製網状部材を介して保冷部材における広い範囲に伝わる。さらに、保冷部材に金属製網状部材の隙間に入り込むように設けられた潜熱蓄熱材を設けたことから、保冷部材における広い範囲において金属製網状部材から潜熱蓄熱材に効率良く熱が伝わる。 Thereby, since the cold insulation member is provided on the upper surface side of the pillow body, when the head is placed on the upper surface side of the pillow body, heat is transmitted to the cold insulation member near the head. Further, since the metal mesh member is provided on the cold insulation member, the heat transmitted to the cold insulation member near the head is transmitted to a wide range of the cold insulation member via the metal mesh member. Furthermore, since the latent heat storage material provided so as to enter the gap of the metal mesh member is provided in the cold insulation member, heat is efficiently transmitted from the metal mesh member to the latent heat storage material in a wide range of the cold insulation member.

本発明によれば、枕本体の上面に頭部が載置されると、頭部近傍の保冷部材に熱が伝わるとともに、その熱が金属繊維群または金属製網状部材を介して保冷部材における広い範囲に伝わり、保冷部材における広い範囲において金属繊維群または金属製網状部材から潜熱蓄熱材に効率良く熱が伝わるので、載置された頭部が移動しない場合でも、頭部近傍の潜熱蓄熱材だけではなく保冷部材における広い範囲の潜熱蓄熱材に頭部の熱が伝わり、頭部の保冷効果を長時間に亘って維持することができる。 According to the present invention, when the head is placed on the upper surface of the pillow body, heat is transmitted to the cold insulation member in the vicinity of the head, and the heat is wide in the cold insulation member via the metal fiber group or the metal mesh member. Since the heat is efficiently transferred from the metal fiber group or the metal mesh member to the latent heat storage material in a wide range of the cold insulation member, even if the placed head does not move, only the latent heat storage material near the head Instead, the heat of the head is transmitted to a wide range of latent heat storage materials in the cold insulation member, and the cold insulation effect of the head can be maintained for a long time.

潜熱蓄熱材２２は粉体から成り、粉体の各粉粒２２ａは、例えば略２５℃で固相から液相に相変化するコア材２２ｂと、コア材２２ｂを収容するカプセル部材２２ｃとを有する（図５参照）。コア材２２ｂとしては、塩化マグネシウム・６水塩、酢酸ナトリウム・３水塩、硝酸マグネシウム・２水塩等の無機化合物系のものや、パラフィンやステアリン酸等の有機化合物系のものが挙げられる。カプセル部材２２ｃはメラミン、ナイロン等のプラスチック材料から成り、コア材２２ｂを覆うように形成されている。潜熱蓄熱材２２の例としては、三菱製紙株式会社製のサーモメモリー（登録商標）や、三木理研工業株式会社製のリケンレジン等が挙げられる。 The latent heat storage material 22 is made of powder, and each particle 22a of the powder includes, for example, a core material 22b that changes from a solid phase to a liquid phase at approximately 25 ° C., and a capsule member 22c that houses the core material 22b. (See FIG. 5). Examples of the core material 22b include inorganic compound materials such as magnesium chloride hexahydrate, sodium acetate trihydrate, magnesium nitrate dihydrate, and organic compound materials such as paraffin and stearic acid. The capsule member 22c is made of a plastic material such as melamine or nylon, and is formed so as to cover the core material 22b. Examples of the latent heat storage material 22 include Thermo Memory (registered trademark) manufactured by Mitsubishi Paper Industries, Inc., and Riken Resin manufactured by Miki Riken Kogyo Co., Ltd.

袋部材２３は金属繊維群２１及び潜熱蓄熱材２２を収容可能に形成され、特に潜熱蓄熱材２２の各粉粒２２ａを収容可能に形成されている。袋部材２３を形成する材料の例としては、ポリエチレン、ポリプロピレン、ナイロン、ポリエステル等の可撓性を有するプラスチック製シートや、金属製フィルムや、表面に金属が蒸着されたプラスチック製のフィルムが挙げられる。袋部材２３は前述のシートやフィルムを１枚または複数枚用いて金属繊維群２１及び潜熱蓄熱材２２を収容している。金属繊維群２１及び潜熱蓄熱材２２の収容は、袋部材２３内に金属繊維群２１を収容した後、潜熱蓄熱材２２を袋部材２３内に充填し、袋部材２３に適度な振動を加える。これにより、金属繊維群２１の各金属繊維同士の隙間に粉体である潜熱蓄熱材２２が入り込む。尚、袋部材２３内を複数の室に分割するとともに、各室をそれぞれ使用者幅方向に延びるように形成し、各室内にそれぞれ金属繊維群２１及び潜熱蓄熱材２２を収容することも可能である。 The bag member 23 is formed so as to be able to accommodate the metal fiber group 21 and the latent heat storage material 22, and is particularly formed so as to be able to receive each powder particle 22 a of the latent heat storage material 22. Examples of the material forming the bag member 23 include flexible plastic sheets such as polyethylene, polypropylene, nylon, and polyester, metal films, and plastic films with metal deposited on the surface. . The bag member 23 contains the metal fiber group 21 and the latent heat storage material 22 using one or a plurality of the above-described sheets and films. The housing of the metal fiber group 21 and the latent heat storage material 22 is performed by filling the latent heat storage material 22 in the bag member 23 after the metal fiber group 21 is stored in the bag member 23 and applying appropriate vibration to the bag member 23. Thereby, the latent heat storage material 22 which is powder enters the gap between the metal fibers of the metal fiber group 21. In addition, while dividing the inside of the bag member 23 into a plurality of chambers, each chamber can be formed so as to extend in the user width direction, and the metal fiber group 21 and the latent heat storage material 22 can be accommodated in each chamber. is there.

保冷部材２０は枕本体１０のカバー部材１２におけるポケット１２ａ内に収容される。これにより、保冷部材２０が枕本体１０の上面側に配置される。また、ポケット１２ａ内に収容された保冷部材２０は、枕本体１０の上面側における使用者丈方向の下端から所定距離Ｌ１だけ離れた位置且つ使用者丈方向の上端から所定距離Ｌ２だけ離れた位置に使用者幅方向に延びるように配置される（図１及び図３参照）。これにより、使用者の肩近傍が無用に保冷されることがない。前記所定距離Ｌ１は３０ｍｍ以上１００ｍｍ以下であることが好ましく、３０ｍｍ未満の場合は、使用者の肩付近を無用に保冷する傾向があり、１００ｍｍを超える場合は、保冷部材２０と頭部とが接する接触面積が小さくなり、後述する頭部の保冷効果が低減する傾向がある。前記所定距離Ｌ２は３０ｍｍ以上１００ｍｍ以下であることが好ましく、３０ｍｍ未満である場合は、保冷部材２０の体積が大きくなる傾向があり、製造コストの低減を図る上で有利ではなく、１００ｍｍを超える場合は、保冷部材２０と頭部とが接する接触面積が小さくなり、後述する頭部の保冷効果が低減する傾向がある。 The cold insulation member 20 is accommodated in the pocket 12 a in the cover member 12 of the pillow body 10. Thereby, the cold insulation member 20 is arrange | positioned at the upper surface side of the pillow main body 10. FIG. Moreover, the cold insulation member 20 accommodated in the pocket 12a is a position away from the lower end in the user length direction on the upper surface side of the pillow body 10 by a predetermined distance L1 and a position away from the upper end in the user length direction by a predetermined distance L2. It arrange | positions so that it may extend in a user width direction (refer FIG.1 and FIG.3). As a result, the vicinity of the user's shoulder is not unnecessarily cooled. The predetermined distance L1 is preferably not less than 30 mm and not more than 100 mm. When the distance is less than 30 mm, there is a tendency to cool the vicinity of the user's shoulder unnecessarily. There is a tendency that the contact area is reduced and the cooling effect of the head, which will be described later, is reduced. The predetermined distance L2 is preferably 30 mm or more and 100 mm or less, and if it is less than 30 mm, the volume of the cold insulation member 20 tends to increase, which is not advantageous for reducing the manufacturing cost, and exceeds 100 mm. The contact area where the cold insulation member 20 and the head are in contact with each other is reduced, and the cold insulation effect of the head described later tends to be reduced.

また、枕本体１０のカバー部材１２におけるポケット１２ａ内には、芳香剤を収容した芳香剤収容部材としての芳香剤袋３０も配置される。芳香剤袋３０は天然繊維や合成繊維から成る布材を用いて形成されている。このため、収容している芳香剤の香りを外部に放出可能である。また、芳香剤の例としては、樹木やハーブ等の植物を乾燥して成る乾燥樹葉や、前記植物から抽出された油を含ませたゲル状物質、粒状物質、粉状物質や、その他周知の様々な芳香剤を使用することが可能である。 Further, in the pocket 12a of the cover member 12 of the pillow body 10, a fragrance bag 30 as a fragrance containing member that contains a fragrance is also arranged. The fragrance bag 30 is formed using a cloth material made of natural fibers or synthetic fibers. For this reason, the fragrance of the stored fragrance can be released to the outside. Examples of the fragrances include dried tree leaves obtained by drying plants such as trees and herbs, gel-like substances, granular substances, powdered substances containing oil extracted from the above-mentioned plants, and other well-known substances. Various fragrances can be used.

以上のように構成された保冷機能付き枕は例えばベッドや布団に載置され、使用者の頭部を支持するために用いられる。また、保冷部材２０によって使用者の頭部を保冷するようになっている。 The pillow with a cold insulation function configured as described above is placed on, for example, a bed or a futon and used to support the user's head. In addition, the user's head is cooled by the cold insulating member 20.

例えば、保冷機能付き枕を外気温が２０℃の場所に放置しておくと、保冷部材２０の潜熱蓄熱材２２も２０℃となり、潜熱蓄熱材２２のコア材２２ｂが固相となる。この状態で、保冷機能付き枕に使用者の頭部が載置されると、枕本体１０の上面側に保冷部材２０が設けられていることから、頭部近傍の保冷部材２０に熱が伝わる。ここで、保冷部材２０に金属繊維群２１を設けたことから、頭部近傍の保冷部材２０に伝わった熱が金属繊維群２１を介して保冷部材２０における広い範囲に伝わる。また、潜熱蓄熱材２２が金属繊維群２１の各金属繊維同士の隙間に入り込むように設けられていることから、保冷部材２０における広い範囲において金属繊維群２１から潜熱蓄熱材２２に効率良く熱が伝わる。 For example, if the pillow with a cold insulation function is left in a place where the outside air temperature is 20 ° C., the latent heat storage material 22 of the cold insulation member 20 also becomes 20 ° C., and the core material 22b of the latent heat storage material 22 becomes a solid phase. In this state, when the user's head is placed on the pillow with the cold insulation function, since the cold insulation member 20 is provided on the upper surface side of the pillow body 10, heat is transmitted to the cold insulation member 20 near the head. . Here, since the metal fiber group 21 is provided in the cold insulation member 20, the heat transmitted to the cold insulation member 20 in the vicinity of the head is transmitted to a wide range in the cold insulation member 20 through the metal fiber group 21. Further, since the latent heat storage material 22 is provided so as to enter the gaps between the metal fibers of the metal fiber group 21, heat is efficiently transferred from the metal fiber group 21 to the latent heat storage material 22 in a wide range of the cold insulation member 20. It is transmitted.

このように、本実施形態によれば、枕本体１０の上面側に頭部が載置されると、頭部近傍の保冷部材２０に熱が伝わるとともに、その熱が金属繊維群２１を介して保冷部材２０における広い範囲に伝わり、保冷部材２０における広い範囲において金属繊維群２１から潜熱蓄熱材２２に効率良く熱が伝わるので、載置された頭部が移動しない場合でも、頭部近傍の潜熱蓄熱材２２だけではなく保冷部材２０における広い範囲の潜熱蓄熱材２２に頭部の熱が伝わり、頭部の保冷効果を長時間に亘って維持することができる。 Thus, according to this embodiment, when the head is placed on the upper surface side of the pillow body 10, heat is transmitted to the cold insulation member 20 in the vicinity of the head, and the heat is transmitted through the metal fiber group 21. Since the heat is efficiently transferred from the metal fiber group 21 to the latent heat storage material 22 in the wide range of the cold insulation member 20 in the cold insulation member 20, even if the placed head does not move, the latent heat near the head is transferred. The heat of the head is transmitted not only to the heat storage material 22 but also to a wide range of latent heat storage materials 22 in the cold insulation member 20, and the cold insulation effect of the head can be maintained for a long time.

また、頭部が載置されていない部分において保冷部材２０が冷却され、その冷熱が金属繊維群２１を介して頭部近傍の潜熱蓄熱材２２に伝わるので、頭部の保冷効果を長時間に亘って維持する上で極めて有利である。 In addition, the cold insulation member 20 is cooled in the portion where the head is not placed, and the cold heat is transmitted to the latent heat storage material 22 in the vicinity of the head via the metal fiber group 21, so that the cold insulation effect of the head is prolonged. It is extremely advantageous to maintain the operation over time.

また、枕本体１０の上面側における使用者丈方向の下端から所定距離Ｌ１だけ離れた位置、且つ、使用者丈方向の上端から所定距離Ｌ２だけ離れた位置に、使用者幅方向に延びるように保冷部材２０を設けたので、使用者の肩近傍が無用に保冷されることがない。 Further, the pillow body 10 extends in the user width direction at a position away from the lower end in the user height direction by a predetermined distance L1 and at a position away from the upper end in the user height direction by a predetermined distance L2. Since the cold insulating member 20 is provided, the vicinity of the user's shoulder is not unnecessarily cooled.

また、保冷部材２０の潜熱蓄熱材２２を粉体から構成したので、潜熱蓄熱材２２を金属繊維群２１における各金属繊維同士の隙間に容易に入り込ませることができ、製造を容易にして製造コストの低減を図る上で極めて有利である。 Further, since the latent heat storage material 22 of the cold insulation member 20 is made of powder, the latent heat storage material 22 can be easily inserted into the gaps between the metal fibers in the metal fiber group 21, facilitating manufacture and manufacturing cost. This is extremely advantageous in reducing the amount of heat.

また、枕本体１０のポケット部１２ａ内に芳香剤を収容している芳香剤袋３０を設け、芳香剤袋３０は収容している芳香剤の香りを外部に放出可能であることから、保冷機能付き枕の近傍に芳香剤の香りを漂わせることができる。 Moreover, since the air freshener bag 30 which stores the air freshener is provided in the pocket part 12a of the pillow main body 10, and the air freshener bag 30 can discharge | release the fragrance of the air freshener stored in the exterior, it is a cold insulation function. The fragrance of the fragrance can be drifted near the pillow.

また、潜熱蓄熱材２２のコア材２２ｂを略２５℃で相変化するように構成したので、２５℃よりも低い外気温において使用する場合に、使用者の頭部を効率的に保冷することができる。 In addition, since the core material 22b of the latent heat storage material 22 is configured to undergo a phase change at approximately 25 ° C., the user's head can be efficiently kept cool when used at an outside air temperature lower than 25 ° C. it can.

尚、本実施形態では、潜熱蓄熱材２２のコア材２２ｂを、略２５℃で相変化するように構成したものを示したが、外気温に応じて他の温度で相変化するように構成することも可能である。 In the present embodiment, the core material 22b of the latent heat storage material 22 is configured to change phase at approximately 25 ° C., but is configured to change phase at other temperatures according to the outside air temperature. It is also possible.

また、本実施形態では、芳香剤袋３０をカバー部材１２のポケット１２ａ内に配置するようにしたものを示したが、芳香剤袋３０を枕本体１０の他の部分に配置することも可能である。また、芳香剤袋３０の代わりにプラスチック等から成る芳香剤収容部材を用いることも可能である。 In the present embodiment, the fragrance bag 30 is arranged in the pocket 12 a of the cover member 12. However, the fragrance bag 30 can be arranged in another part of the pillow body 10. is there. In addition, a fragrance containing member made of plastic or the like can be used instead of the fragrance bag 30.

尚、本実施形態では、潜熱蓄熱材２２を粉体から構成したものを示したが、潜熱蓄熱材２２を粉体が分散している液体またはゲル状体から構成することも可能である。この場合、粉体の各粉粒２２ａは前述の構成を有している。このため、潜熱蓄熱材２２を各金属繊維同士の隙間に容易に入り込ませることができ、製造を容易にして製造コストの低減を図る上で極めて有利である。また、潜熱蓄熱材２２が粉体から構成されている場合と同様の作用効果を達成することができる。 In the present embodiment, the latent heat storage material 22 is made of powder. However, the latent heat storage material 22 may be made of a liquid or gel-like material in which powder is dispersed. In this case, each powder particle 22a of the powder has the above-described configuration. For this reason, the latent heat storage material 22 can be easily inserted into the gaps between the metal fibers, which is extremely advantageous for facilitating the production and reducing the production cost. Moreover, the effect similar to the case where the latent heat storage material 22 is comprised from powder can be achieved.

さらに、潜熱蓄熱材２２を粉体が所定形状に固められて成る粒状体から構成することも可能である。この場合、粉体の各粉粒２２ａは前述の構成を有しており、粒状体の各粒４０の粒径は数百μｍ〜十数ｍｍとなる（図６参照）。また、プラスチックや金属から成る筒状部材５０ａ内に粉体を挿入して固めるとともに、粉体が挿入された筒状部材５０ａを所定の長さに切断することにより、粒状体を構成する各粒５０を形成することも可能である（図７参照）。これらの場合でも、潜熱蓄熱材２２を各金属繊維同士の隙間に容易に入り込ませることができ、潜熱蓄熱材２２が粉体から構成されている場合と同様の作用効果を達成することができる。 Furthermore, the latent heat storage material 22 can be formed of a granular material obtained by solidifying powder into a predetermined shape. In this case, each particle 22a of the powder has the above-described configuration, and the particle size of each particle 40 of the granular body is several hundred μm to several tens of mm (see FIG. 6). Further, the powder is inserted into a cylindrical member 50a made of plastic or metal and hardened, and the cylindrical member 50a into which the powder is inserted is cut into a predetermined length, thereby forming each particle constituting the granular body. 50 can also be formed (see FIG. 7). Even in these cases, the latent heat storage material 22 can be easily inserted into the gaps between the metal fibers, and the same effects as when the latent heat storage material 22 is made of powder can be achieved.
