Description

【0001】
【発明の属する技術分野】
この発明は、パネル本体に線ヒータが内蔵された床仕上材一体型の床暖房パネルに関する。
【0002】
【従来の技術及び発明が解決しようとする課題】
床仕上材として使用される床仕上材一体型の床暖房パネルとしては、図7及び図8に示すようなものがある。この床暖房パネル50は、上面に突板等の表面化粧材52が貼着された5プライ合板等からなるパネル基材53及びこのパネル基材53の裏面側に貼着される裏板54からなるパネル本体51と、パネル基材53の裏面に所定のヒータパターンに沿って形成されたヒータ収容溝53aに収容される線ヒータ55と、この線ヒータ55に結線された状態で、パネル本体51をその短手方向に横断するように、パネル基材53の裏面に形成された電源線収容溝53bに収容される電源線56と、この電源線56の一端側に接続され、パネル基材53に固定される固定側コネクタ57及び電源線56の他端側に接続され、パネル本体51から引き出し可能にパネル基材53に形成された収納凹部53cに収納される可動側コネクタ58とを備えている。
【0003】
ところで、こういったタイプの床暖房パネル50を用いて床暖房フロアを施工する場合は、1枚目の床暖房パネル50を敷設した後、そのパネル基材53の収納凹部53c内に収納されている可動側コネクタ58をパネル本体51から一旦引き出して、次に敷設しようとする床暖房パネル50の固定側コネクタ57に接続し、固定側コネクタ57が接続された可動側コネクタ58を、既に敷設されている床暖房パネル50の収納凹部53cに再び収納するようにして、2枚目の床暖房パネル50を敷設していくといった敷設方法が採用される。
【0004】
しかしながら、前記電源線56は、例えば、図9に示すように、固定側コネクタ57に接続された固定側電源線56aと、可動側コネクタ58に接続された可動側電源線56bとに分離した状態で、両電源線56a、56bの端部同士を、線ヒータ55に接続されたリード線55aと共に、接続端子59を介して相互に接続することによって、電源線56と線ヒータ(リード線55a)55とが結線されるので、床暖房パネル50の敷設時に、可動側コネクタ58が必要以上に大きな力で引き出されると、電源線56と線ヒータ55(リード線55a)との結線部分Aに大きな力が加わり、その結線部分Aに結線不良が発生するおそれがある。しかも、結線不良が発生しているか否かは、通常、床暖房パネル50の敷設後に行われる通電試験等によって発見されるので、そのような結線不良が発生した床暖房パネルの交換作業は手間がかかるものとなっていた。
【0005】
また、裏板54に代えてクッション性の良好な緩衝材を貼着した遮音性を有する直貼りタイプの床暖房パネルでは、可動側コネクタ58を引き出す際に電源線56が位置ずれを起こすことで、線ヒータ(リード線55a)55や電源線56がヒータ収容溝53aや電源線収容溝53bから脱落して、緩衝材とパネル基材53との間に入り込んでしまうことがあり、これによって床暖房パネルの厚みが部分的に厚くなって、綺麗に敷設することができなくなるといった問題もある。
【0006】
そこで、この発明の課題は、パネル敷設時に行われるコネクタの引き出しに伴う電源線と線ヒータとの結線不良を有効に防止することができる床暖房パネルを提供することにある。
【0007】
【課題を解決するための手段及びその効果】
上記の課題を解決するため、請求項1に係る発明は、木質板からなるパネル基材を有するパネル本体と、このパネル本体に内蔵された線ヒータと、前記線ヒータに結線された状態で前記パネル基材を横断するように前記パネル本体内に配設された電源線と、前記電源線の一端側に接続され、前記パネル本体から引き出し可能に、前記パネル基材に形成された収納凹部に収納される可動側コネクタとを備えた床暖房パネルにおいて、前記線ヒータとの結線部分と前記可動側コネクタとの間で前記電源線にストッパ部材を固定し、このストッパ部材を前記パネル基材に形成された係合凹部に嵌め込んで前記可動側コネクタの引き出し方向に係止することによって、前記電源線を前記パネル基材に保持したのである。なお、ここにいう「線ヒータとの結線部分」というのは、電源線と線ヒータとを直接結線した場合は、文字通り、電源線と線ヒータとの結線部分を意味するが、線ヒータをリード線を介して電源線に結線した場合には、そのリード線と電源線との結線部分を意味している。
【0008】
以上のように構成された床暖房パネルでは、線ヒータとの結線部分と可動側コネクタとの間で前記電源線にストッパ部材を固定し、このストッパ部材を前記パネル基材に形成された係合凹部に嵌め込んで前記可動側コネクタの引き出し方向に係止することによって、電源線がパネル基材に保持されているので、可動側コネクタがパネル基材に形成された収納凹部から必要以上に大きな力で引き出されたとしても、その大きな引出力が直接電源線と線ヒータとの結線部分に加わることがなく、可動側コネクタを引き出す際に発生する電源線と線ヒータとの結線不良を有効に防止することができる。
【0009】
また、請求項2に係る発明のように、木質板からなるパネル基材を有するパネル本体と、このパネル本体に内蔵された線ヒータと、前記線ヒータに結線された状態で前記パネル基材を横断するように前記パネル本体内に配設された電源線と、前記電源線の一端側に接続され、前記パネル本体から引き出し可能に、前記パネル基材に形成された収納凹部に収納される可動側コネクタとを備えた床暖房パネルにおいて、前記電源線は、2本の電線によって構成されており、前記電源線の前記線ヒータとの結線部分と前記可動側コネクタとの間において2本の前記電線を結束し、その結束部分を係止する係止部材を前記パネル基材に設けることによって、前記電源線を前記パネル基材に保持するようにしてもよい。
【0010】
また、請求項に記載の床暖房パネルのように、前記パネル本体が、前記パネル基材との間に前記線ヒータ及び前記電源線を挟み込むように、前記パネル基材に緩衝材を貼着したものにあっては、可動側コネクタを収納凹部から引き出す際に電源線が位置ずれを起こすことで、線ヒータや電源線が緩衝材とパネル基材との間に入り込んでしまい、床暖房パネルの厚みが部分的に厚くなるといった問題も有効に防止することができる。
【0011】
【発明の実施の形態】
以下、実施の形態について図面を参照して説明する。図1及び図2に示すように、この床暖房パネル1は、コンクリートスラブの上に直接敷設される直貼工法用の床暖房パネルであり、雁行形状のパネル本体11と、このパネル本体11に内蔵される線ヒータ15及び2本の電線16a、16bからなる電源線16とを備えている。
【0012】
前記パネル本体11は、図2に示すように、表面に突板等の表面化粧材12が貼着された5プライ合板等の木質板からなるパネル基材13と、多数のポリエステル繊維を交絡させたクッション性の良好な緩衝材14とから構成されており、この緩衝材14は、線ヒータ15をパネル基材13との間に挟み込むようにして、パネル基材13の裏面に塗布された接着剤によってパネル基材13の裏面に貼着されている。
【0013】
前記パネル基材13は、図1に示すように、4枚の基材ピースを長手方向にずらしながら雁行状に接続したものであり、このパネル基材13の裏面には、短手方向に延びる多数の切溝13a(図1では省略してある)と、長手方向の中央部を短手方向に横断する、電源線16を収容するための電源線収容溝13bとを備えている。
【0014】
前記線ヒータ15は、図1に示すように、パネル基材13を略均等に加熱するように、所定のヒータパターンに沿って配線されており、その両端部が、電源線16を構成する2本の電線16a、16bに、図示しないリード線を介してそれぞれ接続されている。
【0015】
前記電源線16には、パネル基材13に固定される固定側コネクタ17と、パネル本体11から引き出し可能にパネル基材13に形成された収納凹部13cに収納される可動側コネクタ18とがそれぞれ接続されており、線ヒータ15の結線部分Aと可動側コネクタ18との間には、ストッパ部材20が固定されている。
【0016】
このストッパ部材20は、図3(a)、(b)、(c)に示すように、樹脂ヒンジ22を介して開閉可能に接続された一対の合成樹脂製の挟持部材21によって構成されており、この挟持部材21によって、電源線16を構成する2本の電線16a、16bを同時に挟み込んで締め付け、図示しないロック機構によって、その締め付け状態をロックすることで、電源線16に固定するようになっている。各挟持部材21には、電線16a、16bがそれぞれ嵌り込む溝状の挟持部21aが形成されており、この挟持部21aの湾曲した挟持面には、各電線16a、16bに対する締め付け力を高めるために、多数の切溝21bが形成されている。
【0017】
このストッパ部材20は、図1及び図4(a)、(b)、(c)に示すように、2本の電線16a、16bに固定した状態で、パネル基材13に形成された係合凹部13dに嵌め込むことによって、線ヒータ15の結線部分Aより可動側コネクタ18側で、電源線16がパネル基材13に保持されるようになっている。
【0018】
以上のように構成された床暖房パネル1を用いて床暖房フロアを施工する場合は、まず、1枚目の床暖房パネル1を敷設し、そのパネル基材13の収納凹部13c内に収納されている可動側コネクタ18をパネル本体11から一旦引き出して、次に敷設しようとする床暖房パネル1の固定側コネクタ17に接続し、2枚目の床暖房パネル1の固定側コネクタ17に接続された可動側コネクタ18を、既に敷設されている床暖房パネル1の収納凹部13cに再び収納しながら、2枚目の床暖房パネル1を敷設していくといった具合に床暖房パネル1の敷設作業が行われる。
【0019】
このような床暖房パネル1の敷設作業において、可動側コネクタ18が必要以上に大きな力で収納凹部13cから引き出された場合でも、線ヒータ15の結線部分Aと可動側コネクタ18との間で、電源線16がストッパ部材20を介してパネル基材13に保持されているので、その大きな引出力が直接電源線16と線ヒータ15との結線部分Aに加わることがなく、床暖房パネル1の敷設作業時に、電源線16と線ヒータ15との結線部分に発生する結線不良を有効に防止することができる。これによって、従来のように、床暖房フロアの施工後に、結線不良の床暖房パネルを交換するといった面倒な作業を行うことがほとんどなくなり、効率よく、床暖房フロアを施工することができる。
【0020】
また、可動側コネクタ18を収納凹部13cから引き出す際に電源線16が位置ずれを起こすことがないので、線ヒータ15(リード線)や電源線収容溝13bから脱落した電源線16が、緩衝材14とパネル基材13との間に入り込んで床暖房パネル1の厚みが部分的に厚くなるといったこともなく、床暖房フロアを常に綺麗に仕上げることができる。
【0021】
図5及び図6は、他の実施形態を示している。これらの床暖房パネルも基本的な構造は、上述した床暖房パネル1と同様であるので、同一構成要素には、同一符号を付してその説明を省略し、異なる部分について詳細に説明する。上述した床暖房パネル1は、電源線16にストッパ部材20を固定し、このストッパ部材20をパネル基材13に形成された係合凹部13dに嵌め込むことによって、電源線16をパネル基材13に保持するようにしているが、これらの床暖房パネルでは、そういったストッパ部材20を使用せずに電源線16をパネル基材13に保持するようにした点で、床暖房パネル1とは異なる。
【0022】
図5に示す床暖房パネルは、同図(a)に示すように、線ヒータ15の結線部分Aと可動側コネクタ18との間において、電源線収容溝13bに電源線16を構成する2本の電線16a、16bを強制的に湾曲させる案内部30が設けられている。この案内部30は、同図(a)、(b)、(c)に示すように、電源線収容溝13bの側壁の一部を、外側に突出させるように湾曲させることによって電源線収容溝13bを幅広に形成すると共に、この電源線収容溝13bの幅広部13eにガイド体31を設けることによって、幅広部13eの湾曲した側壁に沿って各電線16a、16bをそれぞれ通すことができる程度の通路を形成したものであり、このガイド体31は、パネル基材13に電源線収容溝13b(13e)を形成する際に、パネル基材13の一部を残すことによって、パネル基材13に一体的に形成されている。
【0023】
このように、電源線16を構成する電線16a、16bを、湾曲した狭小の通路を通すようにしておくと、その湾曲した狭小の通路を構成している電源線収容溝13b(幅広部13e)及びガイド体31の双方の側壁に、電線16a、16bが接触することによって、電源線16が容易に位置ずれしなくなる。従って、上述した床暖房パネル1と同様に、可動側コネクタ18が必要以上に大きな力で収納凹部13cから引き出された場合でも、その大きな引出力が直接電源線16と線ヒータ15との結線部分Aに加わることがなく、床暖房パネルの敷設作業の際に、電源線16と線ヒータ15との結線部分Aに発生する結線不良や、電源線16が位置ずれすることに伴って、線ヒータ15(リード線)や電源線16がパネル基材13と緩衝材14との間に入り込むといった状態を有効に防止することができる。
【0024】
なお、この実施形態では、案内部30において電線16a、16bを湾曲させるようにしているが、こういったものに限定されるものではなく、例えば、電線16a、16bを屈曲させることによって、パネル基材13に保持することも可能である。
【0025】
また、この実施形態では、2本の電線16a、16bを、それぞれ異なる方向に湾曲させるようにしているが、2本の電線16a、16bをまとめて同方向に湾曲または屈曲させることも可能である。
【0026】
また、この実施形態では、電源線収容溝13bを形成する際に、パネル基材13の一部を残すことによって、ガイド体31を形成するようにしているが、別部材を電源線収容溝13bの幅広部13eに固着するようにしてもよい。
【0027】
図6に示す床暖房パネルは、同図(a)、(b)に示すように、線ヒータ15の結線部分Aと可動側コネクタ18との間において、電源線16を構成する2本の電線16a、16bを結束部材40によって結束すると共に、同図(a)、(c)に示すように、その結束位置よりも可動側コネクタ18側において、その結束部分を、パネル基材13の電源線収容溝13bに形成された係止部材41に係止することで、電源線16をパネル基材13に保持するようにしている。
【0028】
従って、上述した床暖房パネル1と同様に、可動側コネクタ18が必要以上に大きな力で収納凹部13cから引き出された場合でも、その大きな引出力が直接電源線16と線ヒータ15との結線部分Aに加わることがなく、床暖房パネルの敷設作業の際に、電源線16と線ヒータ15との結線部分Aに発生する結線不良や、電源線16が位置ずれすることに伴って、線ヒータ15(リード線)や電源線16がパネル基材13と緩衝材14との間に入り込むといった状態を有効に防止することができる。
【0029】
なお、この実施形態では、係止部材41よりも固定側コネクタ17側において、電源線16を結束するようにしているが、係止部材41を挟んでその両側をそれぞれ結束することも可能である。
【0030】
また、この実施形態では、パネル基材13に電源線収容溝13bを形成する際に、パネル基材13の一部を残すことによって、係止部材41を形成するようにしているが、別部材を電源線収容溝13bに固着するようにしてもよい。その場合、この係止部材41のように、ある程度の厚み(幅)を有するものではなく、例えば、金属片のように厚みのほとんどないものを係止部材として電源線収容溝13bに取り付けておくと、係止部材を挟み込んだ状態の電線16a、16bが外側に張り出すことがないので、電源線収容溝13bの幅を最小限に抑えることができる。
【0031】
また、上述した各実施形態では、単独の床暖房パネルについて説明したが、本発明は、複数の床暖房パネルの各パネル本体に内蔵されたそれぞれの線ヒータが、短手方向に整列された複数のパネル本体をその短手方向に横断する共通の電源線に予め結線されており、その共通の電源線の一端に固定側コネクタが、他端に可動側コネクタがそれぞれ接続されている床暖房パネルユニットについても適用することができる。
【0032】
このような床暖房パネルユニットの場合、少なくとも、可動側コネクタが引き出し可能に収納される一の床暖房パネルについては、線ヒータの結線部分と可動側コネクタとの間において、上述した各手法を用いて、共通の電源線をその床暖房パネルのパネル基材に保持しておかなければならないが、電源線は隣接する床暖房パネル側にも引き出されているので、線ヒータとの結線部分を境にしてその引き出し側についても電源線をパネル基材に保持しておくことが望ましい。さらに、固定側コネクタが保持される床暖房パネルや、コネクタを備えていない中間の床暖房パネルが存在する場合は、そういった床暖房パネルについても、線ヒータの結線部分を境にして電源線の引き出し側をそれぞれ各床暖房パネルのパネル基材に保持しておくことが望ましい。即ち、固定側コネクタが保持される床暖房パネルについては、線ヒータとの結線部分を境にして固定側コネクタの反対側を、また、中間の床暖房パネルについては、線ヒータとの結線部分の両側をそれぞれパネル基材に保持しておくことが望ましい。
【0033】
また、上述した各実施形態では、本発明を、パネル基材13の裏面に緩衝材14を貼着した直貼工法用の床暖房パネルに適用した場合について説明したが、本発明は、緩衝材14に代えて裏板を貼着した捨貼工法用の床暖房パネルについても適用することができることは言うまでもない。

BACKGROUND OF THE INVENTION
The present invention relates to a floor heating material-integrated floor heating panel in which a line heater is incorporated in a panel body.
[0002]
[Prior art and problems to be solved by the invention]
As a floor heating material-integrated floor heating panel used as a flooring material, there are those as shown in FIGS. The floor heating panel 50 includes a panel base 53 made of a 5-ply plywood or the like having a surface decorative material 52 such as a veneer attached to the upper surface, and a back plate 54 attached to the back side of the panel base 53. The panel body 51 is connected to the panel main body 51, the line heater 55 accommodated in the heater accommodating groove 53 a formed along the predetermined heater pattern on the back surface of the panel base 53, and the panel main body 51 in a state connected to the line heater 55. A power supply line 56 accommodated in a power supply line accommodation groove 53b formed on the back surface of the panel base material 53 and one end side of the power supply line 56 are connected to the panel base material 53 so as to cross in the lateral direction. A fixed connector 57 that is fixed and a movable connector 58 that is connected to the other end of the power supply line 56 and is housed in a housing recess 53c formed in the panel base 53 so as to be drawn out from the panel body 51. .
[0003]
By the way, when constructing a floor heating floor using this type of floor heating panel 50, after the first floor heating panel 50 is laid, the floor heating panel 50 is stored in the storage recess 53 c of the panel base 53. The movable side connector 58 that has been pulled out from the panel body 51 is connected to the fixed side connector 57 of the floor heating panel 50 to be laid next, and the movable side connector 58 to which the fixed side connector 57 is connected is already laid. A laying method in which the second floor heating panel 50 is laid so as to be housed again in the housing recess 53c of the floor heating panel 50 being used is employed.
[0004]
However, for example, as shown in FIG. 9, the power supply line 56 is separated into a fixed power supply line 56 a connected to the fixed connector 57 and a movable power supply line 56 b connected to the movable connector 58. Thus, by connecting the ends of the power supply lines 56a and 56b together with the lead wire 55a connected to the line heater 55 via the connection terminal 59, the power supply line 56 and the line heater (lead wire 55a) are connected. 55, when the floor heating panel 50 is laid, if the movable connector 58 is pulled out with a larger force than necessary, the connection portion A between the power line 56 and the line heater 55 (lead wire 55a) is large. A force is applied, and there is a possibility that a connection failure may occur in the connection portion A. Moreover, since whether or not a poor connection has occurred is usually found by an energization test or the like performed after laying the floor heating panel 50, replacement of the floor heating panel in which such a connection failure has occurred is troublesome. It was such a thing.
[0005]
In addition, in a directly attached type floor heating panel having a sound insulation property in which a cushioning material having a good cushioning property is attached instead of the back plate 54, the power line 56 is displaced when the movable connector 58 is pulled out. , The wire heater (lead wire 55a) 55 and the power supply line 56 may fall out of the heater housing groove 53a and the power wire housing groove 53b and get into the space between the cushioning material and the panel base material 53. There is also a problem that the thickness of the heating panel becomes partially thick and cannot be laid cleanly.
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to provide a floor heating panel that can effectively prevent a connection failure between a power supply line and a line heater that accompanies the drawing of a connector that is performed when laying the panel.
[0007]
[Means for solving the problems and effects thereof]
In order to solve the above-mentioned problems, the invention according to claim 1 is directed to a panel main body having a panel base material made of a wooden board, a line heater built in the panel main body, and the wire heater connected to the line heater. A power supply line disposed in the panel main body so as to cross the panel base material, connected to one end side of the power supply line, and drawable from the panel main body, in a storage recess formed in the panel base material In a floor heating panel including a movable side connector to be housed , a stopper member is fixed to the power line between a connection portion with the wire heater and the movable side connector, and the stopper member is attached to the panel base material. The power supply line is held on the panel base material by being fitted into the formed engaging recess and being locked in the pulling direction of the movable connector . As used herein, “wire heater connection” means literally the connection between the power line and the line heater when the power line and the line heater are directly connected. When connected to a power supply line via a wire, it means a connection portion between the lead wire and the power supply line.
[0008]
In the floor heating panel configured as described above, a stopper member is fixed to the power supply line between the connection portion with the wire heater and the movable connector, and the stopper member is engaged with the panel base member. Since the power supply line is held by the panel base material by being fitted in the concave portion and locked in the pulling direction of the movable side connector, the movable side connector is larger than necessary from the storage concave portion formed on the panel base material. Even if it is pulled out by force, the large pulling output is not directly applied to the connection part between the power line and the line heater, effectively eliminating the connection failure between the power line and the line heater that occurs when pulling out the movable connector. Can be prevented.
[0009]
Moreover, like the invention which concerns on Claim 2, the said panel base material in the state connected with the panel main body which has the panel base material which consists of a wooden board, the line heater incorporated in this panel main body, and the said line heater A power supply line disposed in the panel main body so as to traverse, and a movable part that is connected to one end side of the power supply line and that can be pulled out from the panel main body and stored in a storage recess formed in the panel base material In the floor heating panel provided with the side connector, the power line is constituted by two electric wires, and the two power lines are connected between the connection portion of the power line and the line heater and the movable side connector. You may make it hold | maintain the said power supply line in the said panel base material by providing the locking member which binds an electric wire and locks the binding part in the said panel base material.
[0010]
In addition, as in the floor heating panel according to claim 3 , a cushioning material is attached to the panel base so that the panel main body sandwiches the line heater and the power line between the panel base and the panel main body. In this case, when the movable side connector is pulled out from the storage recess, the power supply line is displaced, so that the line heater or the power supply line enters between the cushioning material and the panel base material. It is possible to effectively prevent the problem that the thickness of the film partially increases.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments will be described with reference to the drawings. As shown in FIG.1 and FIG.2, this floor heating panel 1 is a floor heating panel for direct sticking methods laid directly on a concrete slab, and the laminating-shaped panel main body 11 and this panel main body 11 A built-in wire heater 15 and a power supply line 16 including two electric wires 16a and 16b are provided.
[0012]
As shown in FIG. 2, the panel body 11 is entangled with a panel base material 13 made of a wooden board such as a 5-ply plywood having a surface decorative material 12 such as a veneer stuck on the surface, and a large number of polyester fibers. The cushioning material 14 is composed of a cushioning material 14 having a good cushioning property. The cushioning material 14 is an adhesive applied to the back surface of the panel base material 13 so as to sandwich the wire heater 15 between the panel base material 13 and the cushioning material 14. Is attached to the back surface of the panel base 13.
[0013]
As shown in FIG. 1, the panel base material 13 is formed by connecting four base material pieces in a laminating manner while shifting in the longitudinal direction, and extends on the back surface of the panel base material 13 in the short direction. A large number of cut grooves 13a (not shown in FIG. 1) and a power supply line receiving groove 13b for storing the power supply line 16 that crosses the central portion in the longitudinal direction in the short direction are provided.
[0014]
As shown in FIG. 1, the line heater 15 is wired along a predetermined heater pattern so as to heat the panel base material 13 substantially evenly, and both ends thereof constitute a power line 16. The wires 16a and 16b are connected to lead wires (not shown), respectively.
[0015]
The power line 16 includes a fixed connector 17 fixed to the panel base material 13 and a movable side connector 18 stored in a storage recess 13c formed in the panel base material 13 so as to be drawable from the panel body 11. A stopper member 20 is fixed between the connection portion A of the wire heater 15 and the movable connector 18.
[0016]
As shown in FIGS. 3A, 3 </ b> B, and 3 </ b> C, the stopper member 20 includes a pair of synthetic resin sandwiching members 21 that are connected to each other via a resin hinge 22 so as to be opened and closed. The two electric wires 16a and 16b constituting the power supply line 16 are sandwiched and tightened simultaneously by the clamping member 21, and the tightened state is locked by a lock mechanism (not shown) to be fixed to the power supply line 16. ing. Each pinching member 21 is formed with a groove-like pinching portion 21a into which the electric wires 16a and 16b are respectively fitted. The curved pinching surface of the pinching portion 21a increases the clamping force for the electric wires 16a and 16b. In addition, a large number of kerfs 21b are formed.
[0017]
As shown in FIGS. 1 and 4A, 4B, and 4C, the stopper member 20 is engaged with the panel base member 13 while being fixed to the two electric wires 16a and 16b. By fitting in the recess 13 d, the power supply line 16 is held by the panel base material 13 on the movable connector 18 side from the connection portion A of the line heater 15.
[0018]
When constructing a floor heating floor using the floor heating panel 1 configured as described above, first, the first floor heating panel 1 is laid and stored in the storage recess 13c of the panel base 13. The movable connector 18 is pulled out from the panel body 11 and connected to the fixed connector 17 of the floor heating panel 1 to be laid next, and connected to the fixed connector 17 of the second floor heating panel 1. The laying operation of the floor heating panel 1 is performed such that the second floor heating panel 1 is laid while the movable connector 18 is housed again in the housing recess 13c of the floor heating panel 1 that has already been laid. Done.
[0019]
In the laying operation of the floor heating panel 1, even when the movable connector 18 is pulled out from the storage recess 13 c with an unnecessarily large force, between the connection portion A of the wire heater 15 and the movable connector 18, Since the power line 16 is held by the panel base material 13 via the stopper member 20, the large pulling power is not directly applied to the connection portion A between the power line 16 and the line heater 15, and the floor heating panel 1 It is possible to effectively prevent a connection failure occurring in the connection portion between the power supply line 16 and the line heater 15 during the laying operation. As a result, the troublesome work of replacing a poorly connected floor heating panel is hardly performed after the floor heating floor has been constructed, and the floor heating floor can be constructed efficiently.
[0020]
Further, since the power supply line 16 does not shift when the movable connector 18 is pulled out from the storage recess 13c, the power supply line 16 dropped from the wire heater 15 (lead wire) or the power supply line receiving groove 13b is used as a cushioning material. The floor heating floor can be always finished neatly without entering between the panel base material 13 and the panel base material 13 and partially increasing the thickness of the floor heating panel 1.
[0021]
5 and 6 show another embodiment. Since the basic structure of these floor heating panels is the same as that of the floor heating panel 1 described above, the same components are denoted by the same reference numerals, description thereof is omitted, and different portions will be described in detail. In the floor heating panel 1 described above, the stopper member 20 is fixed to the power line 16, and the stopper member 20 is fitted into the engagement recess 13 d formed in the panel base 13, whereby the power line 16 is connected to the panel base 13. However, these floor heating panels are different from the floor heating panel 1 in that the power line 16 is held on the panel base material 13 without using such a stopper member 20.
[0022]
As shown in FIG. 5A, the floor heating panel shown in FIG. 5 has two power source lines 16 in the power source line accommodation groove 13b between the connection portion A of the wire heater 15 and the movable connector 18. A guide portion 30 for forcibly bending the electric wires 16a and 16b is provided. As shown in FIGS. 5A, 5B, and 5C, the guide portion 30 is formed by bending a part of the side wall of the power line housing groove 13b so as to protrude outward. 13b is formed wide and the guide body 31 is provided in the wide portion 13e of the power line housing groove 13b, so that the electric wires 16a and 16b can be passed along the curved side wall of the wide portion 13e. The guide body 31 is formed in the panel base material 13 by leaving a part of the panel base material 13 when forming the power line accommodating groove 13b (13e) in the panel base material 13. It is integrally formed.
[0023]
As described above, when the electric wires 16a and 16b constituting the power supply line 16 are passed through a curved narrow passage, the power supply line accommodation groove 13b (wide portion 13e) constituting the curved narrow passage is provided. And when the electric wires 16a and 16b are in contact with both side walls of the guide body 31, the power line 16 is not easily displaced. Therefore, similarly to the floor heating panel 1 described above, even when the movable side connector 18 is pulled out from the storage recess 13c with an unnecessarily large force, the large pulling output is directly connected to the power line 16 and the line heater 15. A wire heater that does not participate in A, and that is caused by a connection failure occurring in the connection portion A between the power line 16 and the line heater 15 or a displacement of the power line 16 during the laying operation of the floor heating panel. It is possible to effectively prevent a state in which the 15 (lead wire) or the power supply line 16 enters between the panel base material 13 and the buffer material 14.
[0024]
In this embodiment, the electric wires 16a and 16b are bent in the guide portion 30, but the present invention is not limited to this. For example, by bending the electric wires 16a and 16b, the panel base It is also possible to hold it on the material 13.
[0025]
In this embodiment, the two electric wires 16a and 16b are bent in different directions, respectively, but the two electric wires 16a and 16b can be bent or bent in the same direction together. .
[0026]
Moreover, in this embodiment, when forming the power supply line accommodating groove 13b, the guide body 31 is formed by leaving a part of the panel base material 13, but a separate member is used as the power supply line accommodating groove 13b. It may be fixed to the wide portion 13e.
[0027]
As shown in FIGS. 6A and 6B, the floor heating panel shown in FIG. 6 includes two electric wires constituting the power line 16 between the connection portion A of the wire heater 15 and the movable connector 18. 16a and 16b are bundled by the bundling member 40, and the bundling portion is connected to the power line of the panel base 13 at the movable connector 18 side of the bundling position as shown in FIGS. The power supply line 16 is held on the panel base material 13 by being locked to the locking member 41 formed in the housing groove 13b.
[0028]
Therefore, similarly to the floor heating panel 1 described above, even when the movable side connector 18 is pulled out from the storage recess 13c with an unnecessarily large force, the large pulling output is directly connected to the power line 16 and the line heater 15. A wire heater that does not participate in A, and that is caused by a connection failure occurring in the connection portion A between the power line 16 and the line heater 15 or a displacement of the power line 16 during the laying operation of the floor heating panel. It is possible to effectively prevent a state in which the 15 (lead wire) or the power supply line 16 enters between the panel base material 13 and the buffer material 14.
[0029]
In this embodiment, the power supply line 16 is bound on the fixed connector 17 side of the locking member 41. However, both sides of the power supply line 16 can also be bound with the locking member 41 interposed therebetween. .
[0030]
Moreover, in this embodiment, when forming the power supply line accommodating groove 13b in the panel base 13, the locking member 41 is formed by leaving a part of the panel base 13; May be fixed to the power line housing groove 13b. In this case, the locking member 41 does not have a certain thickness (width), but is attached to the power supply line receiving groove 13b as a locking member, for example, a metal piece having almost no thickness. Since the electric wires 16a and 16b sandwiching the locking member do not protrude outward, the width of the power line accommodation groove 13b can be minimized.
[0031]
In each of the above-described embodiments, a single floor heating panel has been described. However, in the present invention, a plurality of line heaters built in each panel body of a plurality of floor heating panels are arranged in the short direction. The floor heating panel is pre-connected to a common power line that crosses the panel body in the short direction, and a fixed connector is connected to one end of the common power line, and a movable connector is connected to the other end It can also be applied to units.
[0032]
In the case of such a floor heating panel unit, at least for one floor heating panel in which the movable connector is retractably housed, the above-described methods are used between the wire heater connection portion and the movable connector. Therefore, the common power line must be held on the panel base of the floor heating panel, but the power line is also drawn out to the adjacent floor heating panel side. Thus, it is desirable to hold the power line on the panel base material on the drawer side. In addition, if there is a floor heating panel that holds the fixed connector or an intermediate floor heating panel that does not have a connector, such a floor heating panel can also be connected to the line heater connection section. It is desirable to hold each side on the panel base material of each floor heating panel. That is, for the floor heating panel that holds the fixed-side connector, the opposite side of the fixed-side connector is connected to the connection portion with the line heater, and for the intermediate floor heating panel, the connection portion with the line heater is It is desirable to hold both sides on the panel substrate.
[0033]
Moreover, although each embodiment mentioned above demonstrated the case where this invention was applied to the floor heating panel for direct sticking methods which stuck the buffer material 14 to the back surface of the panel base material 13, this invention is a buffer material. Needless to say, the present invention can also be applied to a floor heating panel for a discarding method in which a back plate is attached instead of 14.
