次に図面に基づいて本発明の実施の形態につき説明する。図1は本発明の電気ケーブル3を内装した手すり11の横断面図であり、図2はその手すり本体7の電気ケーブル3の外周に嵌着される第1樹脂絶縁体4と芯管5との分解斜視略図である。
この電気ケーブル内装手すりは、手すり本体7と支持体8とからなる。手すり本体7は軸心側から電気ケーブル3と第1樹脂絶縁体4と芯管5と第2樹脂絶縁体6とを有する。電気ケーブル3は各種市販のものを利用でき、これは並列する複数の電線1の外周が一体的に可撓性の軟質樹脂2で被覆されたものである。
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a handrail 11 in which an electric cable 3 according to the present invention is housed. FIG. 2 shows a first resin insulator 4 and a core tube 5 fitted on the outer periphery of the electric cable 3 of the handrail body 7. FIG.
The electric cable-incorporated handrail includes a handrail body 7 and a support body 8. The handrail body 7 includes an electric cable 3, a first resin insulator 4, a core tube 5, and a second resin insulator 6 from the axial center side. Various commercially available electric cables 3 can be used, in which the outer periphery of a plurality of electric wires 1 arranged in parallel is integrally covered with a flexible soft resin 2.

各電線1の外周には絶縁性の被覆17が設けられている。そしてこの例では電気ケーブル3の横断面外周が円形に形成され、その外周に整合する内周を有する半割り状の一対の第1樹脂絶縁体4がその電気ケーブル3の外周に被嵌される。さらに第1樹脂絶縁体4の外周に整合する一対の半割り状の芯管5が第1樹脂絶縁体4の外周に被嵌される。
この例では、一対の第1樹脂絶縁体4の継目4aの位置と芯管5の継目5aの位置とが異なるように電気ケーブル3の外周に被嵌されている。そして、この状態でそれら全体の外周に第2樹脂絶縁体6が一体的に成形される。第2樹脂絶縁体6の厚みは、一例として1mm〜10mm程度とすることができる。この第2樹脂絶縁体6は、溶融状態にある樹脂を連続的に芯管5の外周に供給し、それを冷却しながら軸線方向に全体を搬送することにより、長尺な電気ケーブル3内装の手すり本体7を得ることができる。
An insulating coating 17 is provided on the outer periphery of each electric wire 1. In this example, the outer periphery of the cross section of the electric cable 3 is formed in a circular shape, and a pair of halved first resin insulators 4 having an inner periphery aligned with the outer periphery is fitted on the outer periphery of the electric cable 3. . Further, a pair of halved core tubes 5 aligned with the outer periphery of the first resin insulator 4 are fitted on the outer periphery of the first resin insulator 4.
In this example, it is fitted on the outer periphery of the electric cable 3 so that the position of the joint 4a of the pair of first resin insulators 4 and the position of the joint 5a of the core tube 5 are different. And in this state, the 2nd resin insulator 6 is integrally shape | molded by the outer periphery of those whole. The thickness of the 2nd resin insulator 6 can be about 1 mm-10 mm as an example. This second resin insulator 6 continuously supplies molten resin to the outer periphery of the core tube 5 and conveys the entire resin in the axial direction while cooling it, so that the interior of the long electric cable 3 is provided. The handrail body 7 can be obtained.

なお、芯管5はアルミニウムの押出し管を半割り状に形成したものを用いることができる。また芯管5は、剛性を有する他の金属管、例えば鋼管や銅管の半割り状のものを使用することもできる。さらには、FRP等を用いてもよい。このように半割り状に形成することにより、第1樹脂絶縁体4の回りに容易に取り付けることができる。それと共に剛性が高く全体を直線状に保つことができる。このようにしてなる電気ケーブル3を有する手すり本体7はその長手方向の適宜位置の外周に支持体8を取り付け、一例として壁面13等に締結具12を介して締結固定して手すり11を構成することができる。   The core tube 5 may be an aluminum extruded tube formed in half. Further, the core tube 5 may be made of another metal tube having rigidity, for example, a steel tube or a copper tube having a halved shape. Furthermore, FRP or the like may be used. Thus, by forming in half shape, it can be easily attached around the first resin insulator 4. At the same time, the rigidity is high and the whole can be kept linear. The handrail main body 7 having the electric cable 3 thus configured has a support 8 attached to an outer periphery at an appropriate position in the longitudinal direction, and as an example, the handrail 11 is fastened and fixed to a wall surface 13 or the like via a fastener 12. be able to.

なお、支持体8は床面から立ち上げたものであってもよい。また、この例では手すり本体7の断面外周が円形に形成されているが、それに代えて断面外周を楕円形その他にすることができる。
このような手すり本体7は適宜長さを定尺として、複数の手すり本体7をケーブル継手10を介して図3のごとく直列に接続することができる。
The support 8 may be raised from the floor surface. Further, in this example, the outer periphery of the handrail body 7 is formed in a circular shape, but instead, the outer periphery of the cross section can be elliptical or the like.
Such a handrail main body 7 can be connected in series as shown in FIG. 3 via a cable joint 10 with a length as appropriate and a plurality of handrail main bodies 7.

図3は手すり本体7どうしを直列に接続するケーブル継手10の軸線状の縦断面図であり、手すり本体7の両端部は芯管5および第2樹脂絶縁体6が第1樹脂絶縁体4よりも突出され、その芯管5の先端内周面に環状溝の係合部16を設けておく。そして電気ケーブル3の軟質樹脂2の端面から芯線1を露出させ、その先端に金属管を締結固定しておく。この例のケーブル継手10は、複数の孔部22を有する内部樹脂絶縁体21の外周に一対の半割り状の芯管19が被嵌され、その外周に外部樹脂絶縁体20が一体的に形成され、孔部22内に接続用の電極を構成する板バネ18が挿入されている。   FIG. 3 is an axial longitudinal sectional view of a cable joint 10 that connects the handrail bodies 7 in series. The annular tube engaging portion 16 is provided on the inner peripheral surface of the tip of the core tube 5. And the core wire 1 is exposed from the end surface of the soft resin 2 of the electric cable 3, and the metal tube is fastened and fixed to the front-end | tip. In the cable joint 10 of this example, a pair of halved core tubes 19 are fitted on the outer periphery of an inner resin insulator 21 having a plurality of holes 22, and an outer resin insulator 20 is integrally formed on the outer periphery. The leaf spring 18 constituting the connection electrode is inserted into the hole 22.

この板バネ18の長さは孔部22と同一または少し短いものである。それと共に、板バネ18は筒状に形成され、半径方向に拡縮自在に弾性変形するものである。そこで、軟質樹脂2の各電線1の端部を板バネ18に挿入することにより、一対の電気ケーブル3どうしの各電線1を電気的に接続できるものである。なおケーブル継手10は、その両端部の芯管19が外部樹脂絶縁体20よりも突出し、その外周に係止部15が突出して、それが手すり本体7の係合部16に嵌着して係止されるものである。   The length of the leaf spring 18 is the same as or slightly shorter than the hole 22. At the same time, the leaf spring 18 is formed in a cylindrical shape and is elastically deformed so as to be freely expandable and contractable in the radial direction. Therefore, by inserting the end portions of the electric wires 1 of the soft resin 2 into the leaf spring 18, the electric wires 1 between the pair of electric cables 3 can be electrically connected. In the cable joint 10, the core tube 19 at both ends protrudes from the external resin insulator 20, and the locking portion 15 protrudes from the outer periphery, which is fitted into the engaging portion 16 of the handrail body 7. It will be stopped.

次に、図4は本発明の第2の実施の形態を示し、この例の電気ケーブル3はその断面外周が楕円形に形成されたものである。その外周に整合する一対の第1樹脂絶縁体4が電気ケーブル3に被嵌される。他の点は図1のそれと同様であるので省略する。   Next, FIG. 4 shows a second embodiment of the present invention, and the electric cable 3 of this example is formed such that the outer periphery of the cross section is elliptical. A pair of first resin insulators 4 aligned with the outer periphery is fitted on the electric cable 3. The other points are the same as those in FIG.

次に図5は本発明のさらに他の例であり、この例は電力用の電気ケーブル3と通信用ケーブル23とを同時に内装したものである。そして、電気ケーブル3と通信用ケーブル23との外周に整合する凹部を有する一対の第1樹脂絶縁体4によりそれらを被嵌するものである。通信用ケーブル23内には複数の芯線23aが埋設されている。この場合のケーブル継手10は、電力用の接続端子と通信用の接続端子とを設けたものを使用する。
なお、通信用ケーブル23の代わりに、あるいはそれと共に、芯管5を導波管として利用し、その内部に電磁波を伝搬し、通信路として使用することも可能である。この場合にはその通信路の一端部と他端部あるいは中間部に図示しないアンテナを設ければよい。
Next, FIG. 5 shows still another example of the present invention, in which the electric cable 3 for power and the communication cable 23 are installed at the same time. Then, they are fitted by a pair of first resin insulators 4 having recesses aligned with the outer peripheries of the electric cable 3 and the communication cable 23. A plurality of core wires 23 a are embedded in the communication cable 23. In this case, the cable joint 10 is provided with a power connection terminal and a communication connection terminal.
It is also possible to use the core tube 5 as a waveguide instead of or together with the communication cable 23, propagate electromagnetic waves therein, and use it as a communication path. In this case, an antenna (not shown) may be provided at one end portion and the other end portion or the intermediate portion of the communication path.

次に図6は、本発明の他の実施の形態を示し、図1のそれと異なる点は、第1樹脂絶縁体4および芯管5に継目がない点である。このような樹脂は一例として次のようにして形成することができる。
先ず図7のごとく、断面円形の芯管5内に電気ケーブル3を挿通し、その電気ケーブル3を両側から外力を加えて引っ張ることにより張設し、電気ケーブル3の外周と芯管5の隙間を均一にする。なお、必要に応じて電気ケーブル3の適宜位置にプラスチック等の絶縁材からなる脚24を取り付けることにより、芯管5と電気ケーブル3との隙間を一定に確保することができる。
Next, FIG. 6 shows another embodiment of the present invention. The difference from that of FIG. 1 is that the first resin insulator 4 and the core tube 5 are seamless. Such a resin can be formed as follows as an example.
First, as shown in FIG. 7, the electric cable 3 is inserted into the core tube 5 having a circular cross section, and the electric cable 3 is stretched by applying an external force from both sides, and the gap between the outer periphery of the electric cable 3 and the core tube 5 is stretched. Make uniform. In addition, the clearance gap between the core pipe 5 and the electric cable 3 can be ensured by attaching the leg 24 which consists of insulating materials, such as a plastic, to the appropriate position of the electric cable 3 as needed.

このような状態で、芯管5の一端から耐熱性を有する第1樹脂絶縁体4を注入ノズル25で注入し、芯管5と電気ケーブル3との隙間を埋めればよい。なお、第1樹脂絶縁体4は発泡体とすることができる。この場合にも、発泡体として耐熱性を有するものが選択される。ついで、芯管5の外周に第2樹脂絶縁体6が第1実施例同様に一体に形成される。   In such a state, the first resin insulator 4 having heat resistance may be injected from one end of the core tube 5 with the injection nozzle 25 to fill the gap between the core tube 5 and the electric cable 3. The first resin insulator 4 can be a foam. Also in this case, a foam having heat resistance is selected. Next, the second resin insulator 6 is integrally formed on the outer periphery of the core tube 5 as in the first embodiment.
