Description

本発明は、マットレス装置に関し、特に暖房機能が付加されたマットレス装置に関する。 The present invention relates to a mattress device, and more particularly to a mattress device to which a heating function is added.

暖房機能が付加されたマットレス装置としては、例えば、特許文献１に開示のものがある。この暖房ベッドでは、ベッド支持体上に載置された桟木材上に、下部緩衝材、断熱材、面状発熱体、上部緩衝材および伝熱部材を下から順に積層し、面状発熱体と伝熱部材とを熱伝導材で連結し、さらに伝熱部材の上面に綿状体を載置している。かように構成された暖房ベッドにおいては、ベッド支持体上に、下部緩衝材、断熱材、面状発熱体、上部緩衝材および伝熱部材を下から順に積層し、面状発熱体と伝熱部材とを熱伝導材で連結し、さらに伝熱部材の上面に綿状体を載置したことにより、面状発熱体は、下部緩衝材および断熱材と上部緩衝材との間に挟まれた状態となるため、外部からの衝撃によって面状発熱体が損傷するおそれがなくなり、耐衝撃性が向上する。また、面状発熱体の熱は、熱伝導材によって伝熱部材へ効率良く伝えられるため、暖房効率が高まり、伝熱部材の上面にある綿状体をムラなく暖めることが可能となり、均一な暖房効果を得ることができる、という作用効果を奏する。
特開２０００−２０１７７５号公報 An example of a mattress device to which a heating function is added is disclosed in Patent Document 1. In this heating bed, a lower cushioning material, a heat insulating material, a planar heating element, an upper cushioning material, and a heat transfer member are laminated in order from the bottom on a crosspiece placed on the bed support, and the planar heating element and The heat transfer member is connected to the heat transfer member, and a cotton-like body is placed on the upper surface of the heat transfer member. In the heating bed configured as described above, the lower cushioning material, the heat insulating material, the planar heating element, the upper cushioning material, and the heat transfer member are laminated in order from the bottom on the bed support so that the planar heating element and the heat transfer are stacked. By connecting the members with a heat conductive material and placing a cotton-like body on the upper surface of the heat transfer member, the planar heating element was sandwiched between the lower cushioning material and the heat insulating material and the upper cushioning material. Therefore, there is no possibility that the sheet heating element is damaged by an external impact, and the impact resistance is improved. In addition, since the heat of the sheet heating element is efficiently transferred to the heat transfer member by the heat conductive material, the heating efficiency is increased, and the cotton-like body on the upper surface of the heat transfer member can be warmed evenly and uniformly. There is an effect that a heating effect can be obtained.

It may be arranged. In this case, one of the elastic body unit devices composed of the unit elastic body units in one row and the other elastic body device device composed of the unit elastic body units in the other row are heated by separate heating elements. By doing so, it is possible to perform bedtime heating for two persons on the mattress device 10 individually.

凹部２２の内部に重畳的に配置された発熱部材３０及び３個の弾性体ユニット４０・４０・４０が重畳的に配置されたベース２０の上面２６（含：凹部２２の開口部２４）及び側面は、ウレタン樹脂製のキルト部材５０で覆われる。ウレタン樹脂製のキルト部材５０の上面及び側面は、表布地６０で覆われる。しかして、ベース２０の底部には底布地７０が設けられており、表布地６０の周縁部と裏布地７０の周縁部と、図示されないファスナーにより接合され袋体４６０を構成する。ベース２０とキルト部材５０とが袋体４６０により包摂されることにより、マットレス装置１０が完成する。尚、表布地６０及び裏布地７０は、化繊織物で作製される。 An upper surface 26 (including the opening 24 of the recess 22) and side surfaces of the base 20 on which the heat generating member 30 and the three elastic body units 40, 40, and 40 are disposed so as to overlap each other inside the recess 22 are provided. Is covered with a quilt member 50 made of urethane resin. The upper surface and the side surface of the quilt member 50 made of urethane resin are covered with a front fabric 60. Thus, a bottom fabric 70 is provided at the bottom of the base 20, and the peripheral portion of the front fabric 60 and the peripheral portion of the back fabric 70 are joined together by a fastener (not shown) to form a bag body 460. The mattress device 10 is completed by including the base 20 and the quilt member 50 by the bag body 460. The front fabric 60 and the back fabric 70 are made of a synthetic fiber.

弾性体ユニット１は、平板形状の台座部４２と台座部４２の平板面４２ａ上に立設された多数の柱状部材４４と全体を覆う袋体４６から構成されている。台座部４２は、発泡ウレタンで形成されている。柱状部材４４は、円柱状の低硬度エラストマー樹脂で形成されている。低硬度エラストマー樹脂はスチレン系エラストマー樹脂成形品で、スチレン系ベースポリマーにオイルを含有させて製造した。台座部４２と柱状部材４４は、低硬度エラストマー樹脂を溶剤に溶かした接着剤を用いて接合した。 The elastic body unit 1 includes a flat plate-shaped pedestal portion 42, a large number of columnar members 44 erected on the flat plate surface 42 a of the pedestal portion 42, and a bag body 46 that covers the whole. The pedestal portion 42 is formed of foamed urethane. The columnar member 44 is formed of a cylindrical low hardness elastomer resin. The low-hardness elastomer resin is a molded product of a styrene-based elastomer resin, and is produced by adding oil to a styrene-based base polymer. The pedestal portion 42 and the columnar member 44 were joined using an adhesive in which a low-hardness elastomer resin was dissolved in a solvent.

柱状部材４４は全部で７２個設けられ、６個で１列が構成され、図の横方向に１２列設けられている。列は等ピッチで並んでおり、１列中の柱状部材は等ピッチで並んでいる。列方向の柱状部材４４の位置は、隣接する列ごとに列方向の図の右または左方向に半ピッチだけずれて、いわゆる千鳥状に配置されている。柱状部材４４が立設された台座部４２の全体が、袋体４６によって覆われている。袋体４６は弾性変形可能なウレタン材で形成されている。 A total of 72 columnar members 44 are provided, and six of them form one row, and 12 rows are provided in the horizontal direction of the figure. The rows are arranged at an equal pitch, and the columnar members in one row are arranged at an equal pitch. The positions of the columnar members 44 in the column direction are arranged in a so-called zigzag pattern by being shifted by a half pitch in the right or left direction in the column direction for each adjacent column. The entire pedestal portion 42 on which the columnar member 44 is erected is covered with a bag body 46. The bag body 46 is formed of an elastically deformable urethane material.

図５に示されるように、発熱部材３０は、ウレタン樹脂で作製された本体部３２と、この本体部３２の内部にて長手方向に沿ってジグザグ状に延設されるヒータ線３４とから構成される。すなわち、ヒータ線３４は、本体部３２の長手方向に沿って何度も折れ曲がるように配設されており、本体部３２の長手方向の単位長さ当りの、折り返し密度は、図５においては、右側（就寝者の足側に対応）が密になっており、中央側（就寝者の臀部近傍に対応）が疎になっており、左側（就寝者の背中〜肩に対応）がやや密になっている。かようなヒータ線３４の疎密配列により、ヒータ線３４に通電がなされたとき、発熱部材３０の左側（就寝者の足側に対応）、中央側（就寝者の臀部近傍に対応）及び右側（就寝者の背中〜肩に対応）からの発熱量は、相対的には、夫々、大、小、中となる。この大／中／小の熱量は、上昇して、図１の左側の弾性体ユニット４０／中側の弾性体ユニット４０／右側の弾性体ユニット４０を介して、化繊織物で作製されたカバー６０で覆われたウレタン樹脂性のキルト部材５０に至る。 As shown in FIG. 5, the heat generating member 30 includes a main body portion 32 made of urethane resin and a heater wire 34 extending in a zigzag shape along the longitudinal direction inside the main body portion 32. Is done. That is, the heater wire 34 is disposed so as to be bent many times along the longitudinal direction of the main body 32, and the folding density per unit length in the longitudinal direction of the main body 32 is as shown in FIG. The right side (corresponding to the bedside of the sleeping person) is dense, the middle side (corresponding to the vicinity of the bedside of the sleeping person) is sparse, and the left side (corresponding to the sleeping person's back-shoulder) is slightly denser It has become. When the heater wire 34 is energized due to such a dense arrangement of the heater wires 34, the left side (corresponding to the bedside of the sleeping person), the central side (corresponding to the vicinity of the bedside of the sleeping person), and the right side (corresponding to the bedside of the sleeping person) The amount of heat generated from the sleeper's back-shoulder is relatively large, small, and medium, respectively. The large / medium / small amount of heat rises, and the cover 60 made of a synthetic fabric through the left elastic unit 40 / middle elastic unit 40 / right elastic unit 40 in FIG. The urethane resinous quilt member 50 covered with is reached.

図２に示すところから明らかなように、左側の弾性体ユニット４０の内部の柱状部材４４の殆どは、中側の弾性体ユニット４０の内部の柱状部材４４と接触しておらず（右側の弾性体ユニット４０の内部の柱状部材４４の殆どは、中側の弾性体ユニット４０の内部の柱状部材４４と接触しておらず）、また、各弾性体ユニット４０の袋体４６及びキルト部材５０の原料たるウレタン樹脂並びにカバー６０の原材料たる化繊織物は、上方向への熱移動を容易に許容するが、水平方向への熱移動を困難とするので、カバー６０上の就寝者の足側、臀部近傍及びに背中〜肩へは、夫々、相対的に、大量、小量及び中量の熱量が印加されることになる。しかして、大量、小量及び中量の熱が通過する、左側、中側及び右側の弾性体ユニット４０の平面断面積が同一なので、大量、小量及び中量の熱が印加される就寝者の足側、臀部近傍及びに背中〜肩の温度は、図６に示されるグラフのように、相対的に、夫々、高温、低温及び中温となり、理想的な暖房就寝形態が実現できる。つまり、柱状部材４４の間の空間が断熱層としての役割を果たし、水平方向の熱伝導を阻止するので、温度分布の設定が損なわれることがないので、理想的な暖房就寝形態が実現できる。 As is apparent from FIG. 2, most of the columnar members 44 inside the left elastic unit 40 are not in contact with the columnar members 44 inside the middle elastic unit 40 (the right elastic unit 40). Most of the columnar members 44 inside the body unit 40 are not in contact with the columnar members 44 inside the middle elastic body unit 40), and the bag body 46 and the quilt member 50 of each elastic body unit 40 The urethane resin as the raw material and the synthetic fiber fabric as the raw material of the cover 60 allow the heat transfer in the upward direction easily, but make the heat transfer in the horizontal direction difficult. A relatively large amount, a small amount, and a medium amount of heat are applied to the vicinity and back to shoulder, respectively. Thus, the left, middle, and right side elastic body units 40 through which a large amount, a small amount, and a medium amount of heat pass have the same plane cross-sectional area, so that a large amount, a small amount, and a medium amount of heat are applied. As shown in the graph shown in FIG. 6, the foot side, the vicinity of the buttocks, and the back-shoulder temperatures are relatively high, low and medium, respectively, and an ideal heating sleep mode can be realized. That is, the space between the columnar members 44 serves as a heat insulating layer and prevents heat conduction in the horizontal direction, so that the setting of the temperature distribution is not impaired, so that an ideal heating sleep mode can be realized.
