Description

【考案の詳細な説明】【０００１】【考案の属する技術分野】本考案は枕に係り、特に仰向けに寝た使用者の首位置を支持するようにあてがって使用することにより安眠、肩こりの解消を図ることができる枕に関する。【０００２】【従来の技術】従来、就寝時に使用される枕は、頭全体を支持できるような大きさの長方形状の袋状体内にそば殻、羊毛、スポンジ状のウレタンフォーム、短いストロー状のポリエチレン樹脂片等の種々の中詰め材を充填されたものが知られている。いずれの枕も仰向けあるいは側臥して（横向きに寝て）頭を載せたときに、頭の形状に倣って中央部が適度に窪み、頭全体を安定した状態で支持するようになっている。【０００３】従来のこれらの枕に対して、頭と頸椎とをバランスよく支持するようにした変形枕が考案されている（特許文献１参照）。また、仰向けに寝た際に頸椎の湾曲形状を整え、またマッサージ作用により歪んだ状態にある頸椎に適度な矯正を加えるようにした頸椎矯正器がある（特許文献２参照）。【０００４】特許文献１に開示されている枕は、直径が異なる、円弧状にゆるく湾曲した３本の円柱状枕を並列に並べた形状からなり、もっとも太い１本の枕により首位置を支持し、他の２本の枕で後頭部と上頭部とを支持するようになっている。【０００５】また、頸椎矯正器は、かまぼこ形状の枕の下側にバイブレータを装着し、バイブレータを振動させることにより首位置（首筋）を支持するようにした枕を介して頸椎部分に振動を伝え、マッサージ作用をもたらすようにしている。【０００６】【特許文献１】特開平９−３２２８４４号公報。【特許文献２】実開昭６１−１７４９３１号公報。【０００７】【考案が解決しようとする課題】ところで、上述のかまぼこ形状をなす頸椎矯正器は、あらかじめ決まった形状の枕とバイブレータとを組み合わせた健康器具として活用されるものであり、睡眠時の枕として使用することは意図されておらず、首の太さや頸椎の湾曲の具合等、使用者の体格の相違による個人差を考慮することができない。一方、上述の変形枕は充填材の分量や袋端部の折り込み部分の調整により枕の硬さや高さを調整できるようになっている。また、全体が円柱（円筒）形状を連結した形状であるため、仰向けにしてこの枕を使用した場合、太い円柱部分で頸椎の自然な湾曲状態を保持するように首位置を支持するとともに、他の円柱部分で後頭部、上頭部を点支持するようになっている。ところが、この枕を側臥して使用すると、太い円柱部分が頸椎を側方から支持するため、頸椎を側方から曲げようとする好ましくない状態で支持することになり（特開平９−３２２８４４号公報に添付の図５参照）、頭を安定して支持できないばかりでなく、頸椎に悪影響を及ぼすおそれもある。【０００８】そこで、本考案の目的は上述した従来の技術が有する問題点を解消し、仰向けに寝た状態で頸椎を安定よく支持するとともに、後頭部をわずかに床から離れるように頭を支持できるようにし、また側臥した状態でも安定した支持状態で頭を支持できるようにした枕を提供することにある。【０００９】【課題を解決するための手段】上記目的を達成するために、本考案は、仰向けに寝た使用者の後頭部と床との間に隙間が生じるような高さに、中詰め材分量の増減により高さが調整され、使用者の首位置に宛われる中央支持部と、該中央支持部の両側位置に、中央支持部より高さかつ幅が滑らかに大きくなるように形成され、前記使用者の側臥姿勢時に使用者の耳下頬位置ないし耳位置に宛われる両側支持部とからなることを特徴とする。【００１０】【考案の実施の形態】以下本考案による枕の実施の一形態について添付図面を参照して説明する。図１は、本考案の枕の平面図である。この枕１０は、その外形を構成する袋状体１１と、中詰め材１２が袋状体内に充填されることで、図１に示した平面形状、図２に示した正面形状に保形されている。すなわち、この枕１０は、図１に示したように平面視して四隅の角が丸められ、長手方向の中央支持部１０Ａが両側支持部より幅の狭く、くびれた略長方形状をなすとともに、図２（ａ）に示したように正面視して両端が丸められ、中央支持部１０Ａの高さＨ₁が両側支持部１０Ｂの高さＨ₂より低くなるような形状に保形されるように袋状体１１内に充填される中詰め材１２の分量が調整されている。【００１１】本実施の形態では、袋状体１１は木綿等の天然繊維製の布袋からなり、図１，図２（ａ）に示したように、袋側面１３で縫着してなる筒状の袋状体の中央支持部１０Ａに、枕の長手方向に沿ってくびれを設けるためのダーツ１４をつけることで、所望の形状とすることができる。また、立体裁断により得られた生地により、中央支持部１０Ａのくびれた袋状体１１を縫製することも可能である。また、枕１０の長手方向端部にはファスナー１５を取り付けた開口１６が設けられており、中詰め材１２の分量調整のための出し入れが容易にできるようになっている。袋状体１１の素材としては天然繊維の他、速乾性のある合成繊維も適宜使用できる。また枕の外形に合った寸法の、種々の素材の枕カバー（図示せず）を使用することも可能である。【００１２】袋状体１１内部には、本実施の形態ではポリエチレン製の短いストロー状の樹脂片が中詰め材１２として充填されている。中詰め材１２が充填された枕１０は、敷き布団等の床の上に置いた際に、図２（ｂ）に示したように中央のくびれた中央支持部１０Ａが自重でわずかに変形するため、枕１０全体が隙間なく床（布団）上１に置かれる。中詰め材１２は出し入れにより分量調整が可能な材料であれば、公知の種々の材料を使用することができることはいうまでもない。【００１３】この枕１０を使用する場合、図４に示したように、使用者２が仰向けに寝た状態で、首筋４の下側にくびれた中央支持部１０Ａを宛うように位置させる。このとき、枕１０の断面形状はくびれた中央支持部１０Ａと両側支持部１０Ｂとは、ともに中詰め材１２が充填された状態で、図３（ａ），（ｂ）に示したように、楕円ないし長円形状をなしている。これらの中央支持部１０Ａの高さＨ₁と両側支持部１０Ｂの高さＨ₂は、使用者２の頸椎３の湾曲度、首筋４の肉付き等の体格にもよるが、Ｈ₁＝３．５〜７cm,Ｈ₂＝５〜１０cm程度とすることが好ましい。これら高さは、中詰め材１２の分量により適宜調整することができる。また、中央支持部１０Ａの高さは、図４に示したように、後頭部５と床（布団）１との間にわずかな隙間６ができるような高さに設定する。これにより後頭部５が床１に触れないので、頭部に対しての冷却効果が期待できる。さらに、頭部が床に支持されていないので、頭部が左右に動きやすくなっている。したがって睡眠中に無意識に行われるような、頭部をわずかに左右に振る程度の寝返りをうっても頭部を支持する首筋４に適度な刺激が加わり、首筋４、肩のコリ等を解消する効果も期待できる。一方、首筋４が枕１０に接触して暖められ、首位置での血行促進されるという効能もある。また、頭部が首位置で支持され後頭部がわずかに下がった状態では、鼻腔が通りやすくなるので、イビキの防止も期待できる。【００１４】一方、側臥して、すなわち横向きに寝てこの枕１０を使用する場合、図５に示したように両側支持部１０Ｂの一方のなだらかに傾斜している部分あるいは最高部に、使用者２の耳下の頬骨あるいは耳の位置がくるように宛って使用することが好ましい。このとき顔の側面を枕１０の高い部分に位置させるため、横向きに寝ることで肩が体の下に入って頭が高くなった分の高さを解消することができる。寝入りに横向きになる癖のある人は、横向き姿勢で寝入っても、睡眠中に寝返りをうったときに仰向け姿勢になり、その状態で首筋４が中央支持部１０Ａに位置するようになり、その仰向け状態で首位置が確実に支持される。【００１５】図６及び図７は、枕１０の変形例の内部構成を示した断面図である。図６に示した枕１０は外袋状体１１の外形は図１に示した形状と同一であるが、外袋状体１１内には両側支持部１０Ｂに内袋１７が収容されており、その内袋１７内に中詰め材１２が充填されている。さらに中央支持部１０Ａには中詰め材１２が外袋状体１１に直接、充填されるようになっている。このように、枕１０の内部を３ブロックに分割することにより、首位置を支える中央支持部１０Ａと、その両側の両側支持部１０Ｂの硬さと高さを、それぞれ独立して調整することができる。内袋１７としてはメッシュ状の袋を使用することが好ましい。また、この内袋１７を収容させるために外袋状体の両側端に開口１６，１６を設けておくことが好ましい。中央支持部１０Ａと両側支持部１０Ｂの中詰め材１２あるいは枕の材質を変えることもできる。たとえば両側支持部１０Ｂには、中詰め材１２を使用せず、所定の形状に成形加工した軟質ウレタンフォーム等のクッション材をそのまま外袋状体１１内に収容させるようにしてもよい。【００１６】【考案の効果】以上の説明から明らかなように、本考案によれば、仰向けに寝た人の頸椎の湾曲具合に合わせて中央支持部の高さを調整して首筋にフィットするように宛てがうとともに、後頭部が床からわずかに離れるように頭部を支持することができるので、これにより首筋の血行促進、頭部の冷却効果等が得られ、軽い寝返り時の首筋への刺激によりマッサージ効果を期待でき、肩こりの緩和も期待できる。また、首筋を暖めることによって体の免疫力が向上するという研究もあり、同研究で示された効果が確実に現れることも期待できる。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillow, and more particularly to a sleeper who lays on his back to support the neck position of the user, thereby eliminating sleep and stiff shoulders. A pillow that can be used. [0002] Conventionally, a pillow used at bedtime has a buckle, wool, sponge-like urethane foam, and a short straw-like pillow in a rectangular bag-like body large enough to support the entire head. What is filled with various filling materials, such as a polyethylene resin piece, is known. When any of the pillows is placed on its back or lying on its side (sleeping sideways), the central part is appropriately depressed according to the shape of the head, and the whole head is supported in a stable state. With respect to these conventional pillows, a deformed pillow has been devised in which the head and the cervical spine are supported in a well-balanced manner (see Patent Document 1). In addition, there is a cervical vertebra corrector that adjusts the curved shape of the cervical vertebra when lying down on the back and applies an appropriate correction to the cervical vertebra that is distorted by the massage action (see Patent Document 2). The pillow disclosed in Patent Literature 1 has a shape in which three cylindrical pillows having different diameters and loosely curved in an arc shape are arranged in parallel, and the neck position is supported by one thickest pillow. The other two pillows support the back of the head and the upper head. Further, the cervical vertebra corrector has a vibrator attached to the lower side of the pillow having a semi-cylindrical shape, and vibrates the vibrator to transmit vibration to the cervical vertebra through a pillow configured to support a neck position (a nape muscle). , To bring a massage effect. [Patent Document 1] Japanese Patent Application Laid-Open No. 9-322844. [Patent Document 2] Japanese Utility Model Publication No. Sho 61-174931. [0007] By the way, the above-mentioned cervical spine corrector having a kamaboko shape is used as a health device combining a pillow and a vibrator having a predetermined shape, and is used during sleep. It is not intended to be used as a pillow, and it cannot take into account individual differences due to differences in physique of users, such as the thickness of the neck and the degree of curvature of the cervical spine. On the other hand, in the above-mentioned deformed pillow, the hardness and height of the pillow can be adjusted by adjusting the amount of the filler and the folded portion at the end of the bag. In addition, because the entire shape is a cylinder (cylindrical) shape connected, when this pillow is used on its back, it supports the neck position so that the cervical vertebra is held in a natural curved state by the thick cylinder, The occipital and upper heads are point-supported by the columnar part of. However, when this pillow is used sideways, the thick cylindrical portion supports the cervical vertebra from the side, so that the cervical vertebra is supported in an unfavorable state in which the cervical vertebra is bent from the side (Japanese Unexamined Patent Publication No. 9-322844). Not only cannot support the head stably, but also may adversely affect the cervical spine. [0008] Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art, and to stably support the cervical vertebra while lying on the back and to support the head so that the occipital region is slightly away from the floor. It is another object of the present invention to provide a pillow capable of supporting the head in a stable supporting state even when the head is lying down. Means for Solving the Problems To achieve the above object, the present invention provides a padding material having a height such that a gap is formed between the back of the head of a user lying on his back and the floor. The height is adjusted by increasing or decreasing the amount, and a central support portion addressed to the user's neck position, formed at both sides of the central support portion, so that the height and width are smoothly larger than the central support portion, When the user is in the lateral position, the user is characterized in that the user is provided with both side supporting portions directed to the user's lower cheek position or ear position. An embodiment of a pillow according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a plan view of the pillow of the present invention. The pillow 10 is shaped into a plane shape shown in FIG. 1 and a front shape shown in FIG. 2 by filling the bag-like body 11 and the filling material 12 constituting the outer shape into the bag-like body. ing. That is, as shown in FIG. 1, the pillow 10 has four corners that are rounded in plan view, and the central support portion 10A in the longitudinal direction is narrower than the support portions on both sides and has a narrow, substantially rectangular shape. both ends are rounded and the front view as shown FIG. 2 (a), the height H ₁ of the central support portion 10A is shape-retaining shaped to be lower than the height H ₂ of each side support portion 1 0B Thus, the amount of the filling material 12 filled in the bag-like body 11 is adjusted. In the present embodiment, the bag-like body 11 is made of a cloth bag made of a natural fiber such as cotton, and as shown in FIGS. A desired shape can be obtained by attaching a dart 14 for providing a constriction along the longitudinal direction of the pillow to the central support portion 10A of the bag-like body. Further, it is also possible to sew the narrow bag-like body 11 of the central support portion 10A using the cloth obtained by draping. An opening 16 to which a fastener 15 is attached is provided at an end of the pillow 10 in the longitudinal direction, so that the filling material 12 can be easily taken in and out for adjusting the amount. As the material of the bag-like body 11, not only natural fibers but also synthetic fibers having quick drying properties can be used as appropriate. It is also possible to use pillow covers (not shown) of various materials having dimensions that match the outer shape of the pillow. In the present embodiment, the inside of the bag-like body 11 is filled with a short straw-like resin piece made of polyethylene as the filling material 12. When the pillow 10 filled with the filling material 12 is placed on a floor such as a mattress, the constricted central support portion 10A at the center is slightly deformed by its own weight as shown in FIG. 2B. The whole pillow 10 is placed on the floor (futon) 1 without any gap. It goes without saying that various known materials can be used as the filling material 12 as long as the material can be adjusted in quantity by taking in and out. When the pillow 10 is used, as shown in FIG. 4, the user 2 is positioned so that the user 2 lies on his / her back and faces the central support 10 A which is narrowed below the neck 4. At this time, the cross-sectional shape of the pillow 10 is such that the constricted center support portion 10A and both-side support portions 10B are filled with the filling material 12 as shown in FIGS. 3 (a) and 3 (b). It has an elliptical or elliptical shape. Height H ₂ of the height H ₁ and the both side support part 10B of the central support section 10A, curvature of the cervical spine 3 of the user 2, although depending on the size of the fleshy etc. neck 4, H ₁ = 3. 5-7 cm, it is preferable that the H ₂ = 5 to 10 cm approximately. These heights can be appropriately adjusted by the amount of the filling material 12. Further, the height of the center support portion 10A is set to a height such that a slight gap 6 is formed between the back of the head 5 and the floor (futon) 1, as shown in FIG. As a result, the back of the head 5 does not touch the floor 1, so that a cooling effect on the head can be expected. Further, since the head is not supported on the floor, the head can easily move from side to side. Therefore, even when turning over the head slightly to the left or right, which is performed unconsciously during sleep, a moderate stimulus is applied to the neck 4 supporting the head, and the stiffness of the neck 4, the shoulder, etc. are eliminated. The effect can be expected. On the other hand, there is also an effect that the neck 4 is warmed by contacting the pillow 10 and blood circulation at the neck position is promoted. Further, in a state where the head is supported at the neck position and the back of the head is slightly lowered, the nasal cavity becomes easy to pass, so that prevention of irritations can be expected. On the other hand, when the pillow 10 is used while lying on its side, that is, lying on its side, as shown in FIG. It is preferable to use it so that the position of the cheekbone or ear below the ear 2 is located. At this time, since the side surface of the face is positioned at the high portion of the pillow 10, it is possible to eliminate the height corresponding to the height of the head due to the shoulder being under the body by lying down sideways. Even if the person who has a habit of lying sideways to fall asleep, even if lying down in a sideways posture, when turning over while sleeping, the person assumes a supine posture, and in that state the neck 4 is located at the central support portion 10A, The position of the neck is reliably supported in the state of lying on the back. FIGS. 6 and 7 are cross-sectional views showing the internal configuration of a modified example of the pillow 10. The outer shape of the outer bag-like body 11 of the pillow 10 shown in FIG. 6 is the same as the shape shown in FIG. 1, but the inner bag 17 is housed in the outer bag-like body 11 in both side support portions 10B, The filling material 12 is filled in the inner bag 17. Further, the center support portion 10A is filled with the filling material 12 directly into the outer bag-like body 11. As described above, by dividing the inside of the pillow 10 into three blocks, the hardness and height of the central support portion 10A that supports the neck position and the both-side support portions 10B on both sides thereof can be independently adjusted. . It is preferable to use a mesh bag as the inner bag 17. Further, in order to accommodate the inner bag 17, it is preferable to provide openings 16, 16 on both side ends of the outer bag. The material of the middle filling material 12 or the pillows of the central support portion 10A and the both-side support portions 10B can be changed. For example, a cushion material such as a soft urethane foam molded into a predetermined shape may be accommodated in the outer bag-like body 11 without using the middle filling material 12 in the both-side support portions 10B. As is apparent from the above description, according to the present invention, the height of the central support portion is adjusted according to the degree of curvature of the cervical vertebra of a person who lies on his back to fit the neck muscle. The head can be supported so that the back of the head is slightly away from the floor, thereby promoting blood circulation of the neck, cooling the head, etc. Stimulation can be expected to have a massage effect and can also reduce stiff shoulders. In addition, some studies have shown that warming the neck improves the body's immunity, and it is expected that the effects shown in this study will surely appear.
