以下、図示の実施形態に基いて本考案の構成を具体的に詳述すると、その本考案の後付け式ヒーターは図1〜3のようなほぼ長方形の軟質な包袋(B)と、その内部へ出し入れ自在に収容された可撓性のPTC面状発熱シート(フェバーヒーター)(H)とから成り、その包袋(B)によって1人掛け用椅子(C)へ結束使用できるようになっている。   Hereinafter, the configuration of the present invention will be described in detail based on the illustrated embodiment. The retrofit heater of the present invention includes a substantially rectangular soft wrapping bag (B) as shown in FIGS. It consists of a flexible PTC sheet heating sheet (Feber heater) (H) that can be freely inserted and removed, and can be used for binding to a chair for one person (C) by means of its wrapping bag (B). ing.

先ず、PTC面状発熱シート(フェバーヒーター)(H)は図4〜7に抽出するような椅子(C)の座面と対応する帯幅(W)(例えば約30〜40cm)と、適当な一定長さ(L)(例えば約80〜120cm)を備えたほぼ長方形のPET(ポリエチレンテレフタレート)樹脂フィルム(1)上における櫛歯状の正電極(2a)と負電極(2b)との相互間隙をあたかも埋める如く、交互に正温度係数インクで遠赤外線発熱体(3)をスクリーン印刷し、もう1枚のPET樹脂フィルム(4)をサンドイッチ状態に接着一体化したものであり、約2mm以下の厚み(T)に制限されている。   First, the PTC sheet heating sheet (Feber heater) (H) has a band width (W) (for example, about 30 to 40 cm) corresponding to the seating surface of the chair (C) as extracted in FIGS. Between a comb-like positive electrode (2a) and a negative electrode (2b) on a substantially rectangular PET (polyethylene terephthalate) resin film (1) having a certain fixed length (L) (for example, about 80 to 120 cm) The far-infrared heating element (3) is alternately screen-printed with positive temperature coefficient ink as if filling the gap, and another PET resin film (4) is bonded and integrated in a sandwich state, about 2 mm or less The thickness (T) is limited.

そして、その正電極(2a)と負電極(2b)から引き出された導線(5a)(5b)の先端部には、電源コンセントへの差込みプラグ(6)が取り付けられている。(7a)(7b)は接続端子、(8)は上記導線(5a)(5b)を被覆する螺旋状の透明な樹脂カバーであって、椅子(C)が回転するも絡らみ付いたり、踏み潰されたりしないようになっている。   An insertion plug (6) to a power outlet is attached to the tip of the conducting wires (5a) (5b) drawn from the positive electrode (2a) and the negative electrode (2b). (7a) and (7b) are connection terminals, and (8) is a spiral transparent resin cover that covers the conductive wires (5a) and (5b), and the chair (C) rotates, It is designed not to be crushed.

茲に、遠赤外線発熱体(3)となる正温度係数インクは、P型半導体の一種から構成されており、その発熱体(3)の温度が高くなるに連れて、電気抵抗値が急増する性質(PTC特性)を有する。この点、本考案は1人掛け用椅子へ着席した人の下半身又は/及び上半身を暖房するものとして、その遠赤外線発熱体(3)の温度が予じめ約30℃〜約80℃に設定されている。そのため、この設定温度に達すると、電気抵抗の急増により、通電が急減し、遠赤外線発熱体(3)の温度は設定温度以上に上昇せず、自己温度制御機能を発揮する。サーモスタットなどを用いて温度調整しなくとも、過熱の危険がないのである。   Furthermore, the positive temperature coefficient ink used as the far-infrared heating element (3) is composed of a kind of P-type semiconductor, and the electrical resistance value increases rapidly as the temperature of the heating element (3) increases. It has properties (PTC characteristics). In this regard, the present invention assumes that the temperature of the far-infrared heating element (3) is set to about 30 ° C. to about 80 ° C. in order to heat the lower body and / or upper body of a person seated in a chair for one person. Has been. Therefore, when this set temperature is reached, the energization is suddenly reduced due to a rapid increase in electrical resistance, and the temperature of the far-infrared heating element (3) does not rise above the set temperature, and the self-temperature control function is exhibited. There is no danger of overheating without adjusting the temperature using a thermostat.

次に、包袋(B)は軟らかい表布(9a)と裏布(9b)とから、上記PTC面状発熱シート(H)を収容できる一定な大きさ(例えば幅が約35〜45cm×長さが約85〜150cmの長方形)に縁取り縫製されており、その表布(9a)又は裏布(9b)の短辺と平行に切り欠かれた面状発熱シート用出し入れ口(10)には、開閉ファスナー(11)が取り付けられている。(12)は上記PTC面状発熱シート(H)の導線(5a)(5b)を導出させるための貫通口である。但し、包袋(B)の素材としては上記面状発熱シート(H)を包囲できる1枚物の布地やフエルト、軟質の合成樹脂発泡体などを採用しても良い。   Next, the wrapping bag (B) has a certain size (for example, a width of about 35 to 45 cm × long) that can accommodate the PTC sheet heating sheet (H) from the soft front cloth (9a) and the back cloth (9b). Is about 85 to 150 cm in length), and the sheet heating / unloading port (10) cut out in parallel with the short side of the front cloth (9a) or the back cloth (9b) The opening / closing fastener (11) is attached. (12) is a through-hole for leading out the conducting wires (5a) and (5b) of the PTC sheet heating sheet (H). However, as the material of the wrapping bag (B), a single piece of cloth or felt that can surround the planar heating sheet (H), a soft synthetic resin foam, or the like may be used.

又、同じく包袋(B)の四隅部とほぼ中間部には上中下として並列する一対づつのリベット(ハトメ)(13a)(13b)がかしめ付けられており、ここへ抜き差し自在に通し込まれた一定長さの結束紐(14a)(14b)を使って、上記PTC面状発熱シート(H)が収容された包袋(B)を、図8〜10のように椅子(C)の座面(15)やその脚柱(16)、背凭れ(17)の支柱(18)、肘掛け(19)の支柱(20)、その他の一部へ締結できるようになっている   Similarly, a pair of rivets (eyelets) (13a) and (13b) arranged in parallel as upper, middle and lower sides are caulked at the four corners and almost the middle part of the wrapping bag (B). Using the bundled straps (14a) and (14b) of a certain length, the wrapping bag (B) containing the PTC sheet heating sheet (H) is attached to the chair (C) as shown in FIGS. It can be fastened to the seat surface (15), its pedestal (16), the backrest (17) strut (18), the armrest (19) strut (20), and other parts.

その場合、包袋(B)は自由に折りたたんだり、巻き曲げたりすることができるが、その内部のPTC面状発熱シート(H)はPET樹脂フィルム(1)(4)から約2mm以下の厚み(T)に接着一体化されているため、滑らかな円弧状に巻き曲げることはできるが、折れ目が生ずる重合状態に折り返し扁平化することは不可能である。   In that case, the wrapping bag (B) can be folded or bent freely, but the PTC sheet heating sheet (H) inside the bag (B) has a thickness of about 2 mm or less from the PET resin films (1) and (4). Since it is bonded and integrated to (T), it can be wound into a smooth arc shape, but it cannot be folded and flattened into a polymerized state in which a crease occurs.

そこで、本考案のヒーターを1人掛けの椅子(C)へ後付け使用するに当っては、その包袋(B)に収容された面状発熱シート(H)を図8のようなほぼL字形に屈曲させて、その包袋(B)の上部に位置する結束紐(14a)(14b)を椅子(C)の背凭れ(17)へ、中間部の結束紐(14a)(14b)を背凭れ(17)の支柱(18)へ、更に下部の結束紐(14a)(14b)を座面(15)の脚柱(16)へ各々締結し、上記面状発熱シート(H)から引き出された導線(5a)(5b)の差込みプラグ(6)を、室内の電源コンセントへ差し込み使用すれば良い。そうすれば、その椅子(C)へ着席した人の上半身を、面状発熱シート(H)からの伝熱作用により暖房することができる。   Therefore, when the heater of the present invention is retrofitted to a chair (C) for one person, the sheet heating sheet (H) accommodated in the bag (B) is substantially L-shaped as shown in FIG. The binding ties (14a) and (14b) located at the top of the bag (B) are bent to the backrest (17) of the chair (C), and the binding ties (14a) and (14b) in the middle are Fasten the brace (17) to the support column (18) and the lower tying string (14a) (14b) to the pedestal (16) of the seating surface (15), respectively, and pull it out from the sheet heating sheet (H). The plug (6) of the conducting wires (5a) and (5b) may be used by inserting it into an indoor power outlet. Then, the upper body of the person seated on the chair (C) can be heated by the heat transfer action from the sheet heating sheet (H).

又、上記面状発熱シート(H)を図9のようなほぼ倒立L字形に屈曲させて、やはり包袋(B)の上部に位置する結束紐(14a)(14b)を椅子(C)における背凭れ(17)の支柱(18)へ、中間部と下部の結束紐(14a)(14b)を何れも座面(15)の脚柱(16)へ各々締結することにより、その椅子(C)へ着席した人の下半身を上記と同様に暖房することができる。   Further, the sheet heating sheet (H) is bent into an almost inverted L shape as shown in FIG. 9, and the tying strings (14a) and (14b) located at the upper part of the wrapping bag (B) are also attached to the chair (C). The chair (C) can be obtained by fastening the middle and lower binding strings (14a), (14b) to the pillars (16) of the seat surface (15), respectively, to the support (18) of the backrest (17). ) Can be heated in the same way as above.

更に、上記包袋(B)とこれに収容された面状発熱シート(H)の長さ次第では、これを図10のような連続する階段形態に屈曲させて、その複数本の結束紐(14a)(14b)を椅子(C)の一部へ安定良く締結することにより、その椅子(C)へ着席した人の上半身と下半身を全体的に暖房することも可能である。   Further, depending on the length of the wrapping bag (B) and the sheet heating sheet (H) accommodated in the wrapping bag (B), the wrapping bag (B) is bent into a continuous staircase shape as shown in FIG. By fastening 14a) and 14b to a part of the chair (C) in a stable manner, it is possible to heat the upper body and lower body of the person seated on the chair (C) as a whole.

そして、その何れにしても本考案の不使用時には滑らかなロール状態に巻き曲げて、その小型コンパクトに保管することができ、又面状発熱シート(H)の交換やその包袋(B)の清掃なども行なえるため、著しく便利であり、1人掛け用の各種椅子(C)に対する汎用性にも優れる。その椅子(C)としては回転式と非回転式との種別や肘掛け(18)の有無を問わず、更に脚柱(16)の本数も問わず、本考案をあらゆる形態の椅子(C)に後付け使用することができる。   In any case, when the present invention is not used, it can be rolled into a smooth roll and stored in a compact and compact form. Also, the sheet heating sheet (H) can be replaced and the packaging (B) Since cleaning and the like can be performed, it is extremely convenient and excellent in versatility for various chairs (C) for one person.
