Abstract

<P>PROBLEM TO BE SOLVED: To provide a handrail connector which assures connection and can comply with the elongations and contractions of a covering material by temperatures. <P>SOLUTION: A connector which connects a core material to a handrail member comprising a covering material for covering the core material comprises a covering part with one side of a cylindrical surface opened along the longitudinal direction and an abutting part provided to the inner surface wall of the covering part, wherein the abutting part is made to abut on the core material outer wall of the handrail member to which the abutting part is connected, and the inner surface of the covering part is made to abut on the covering member. Thus, the handrail connector can be fixed to the core material of the handrail member to which the handrail connector is connected, which enables easy correspondence to changes caused by the difference of linear expansion coefficients between the core material and the covering agent, enhancing the bonding properties between the handrail member and the handrail connector. Furthermore, the handrail connector can be mounted to the core material of the handrail member, enabling the connection to be executed rigidly, irrespective of the quality of the covering materials. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、階段や廊下などの壁面に設置される手摺において、手摺部材と手摺部材を接続するための手摺用接続具に関し、特に金属製の芯材に合成樹脂製被覆材を被せた手摺部材に好適に用いられる手摺用接続具に関する。 The present invention relates to a handrail connection tool for connecting a handrail member and a handrail member in a handrail installed on a wall such as a staircase or a corridor, and in particular, a handrail member in which a metal core is covered with a synthetic resin coating. It is related with the handrail connection tool used suitably for.

特開平１０−１８５３６号公報従来、特開平１０−１８５３６号公報には、線膨張係数が異なる長尺部材を厚さ方向に複数個組み合わせた複合手摺同士の端部を長手方向に沿って接続するために当該複合手摺同士の端部間に挟み込まれるジョイントリングであって、そのジョイントリングは、複合手摺を形成する各々の長尺部材よりも軟らかな軟質材から形成されていることを特徴とするジョイントリングが提案されている。JP, 10-18536, A Conventionally, JP, 10-18536, A connects the end part of compound handrails which combined two or more long members from which a linear expansion coefficient differs in the thickness direction along the longitudinal direction. Therefore, the joint ring is sandwiched between the ends of the composite handrails, and the joint ring is formed of a soft material softer than each long member forming the composite handrail. Joint rings have been proposed.

又、手摺部材の被覆材に筒状の接続具を被せ、被覆材と接続具を粘着剤などの接着剤で接着するという方法が知られている。 In addition, a method is known in which a covering member of a handrail member is covered with a cylindrical connecting member, and the covering member and the connecting member are bonded with an adhesive such as an adhesive.

しかしながら上記の如き特開平１０−１８５３６号公報に提案されているジョイントリングにおいては、手摺の長手方向の線膨張に対しても対応することができて、外観を良好に維持することができるという効果があるものの、接続部分に必ず手摺継手ブラケットを使わねばならないという問題があった。又、ジョイントリングの弾性変形によってのみ各部材の変形に対応しているため大きな変形に対応することができないという問題があった。
又、合成樹脂製被覆材に筒状の接続具を被せて粘着剤などの接着剤で固定するという方法においては、合成樹脂製被覆材がエラストマーなどの軟質合成樹脂から一般には作製されるが、この軟質合成樹脂が一般の粘着剤と接着性が悪いという問題があった。 However, in the joint ring proposed in Japanese Patent Laid-Open No. 10-18536 as described above, it is possible to cope with the linear expansion in the longitudinal direction of the handrail, and it is possible to maintain a good appearance. However, there is a problem that a handrail joint bracket must be used for the connection part. Further, since the deformation of each member is supported only by the elastic deformation of the joint ring, there is a problem that it is not possible to cope with a large deformation.
In addition, in the method of covering a synthetic resin coating material with a cylindrical connector and fixing it with an adhesive such as an adhesive, the synthetic resin coating material is generally made from a soft synthetic resin such as an elastomer. There was a problem that this soft synthetic resin had poor adhesiveness with a general pressure-sensitive adhesive.

そこで本発明者は従来の欠点に鑑み鋭意研究の結果、接続が確実で、被覆材の温度による伸び縮みに対しても対応が可能な手摺用接続具を提供する。 In view of the conventional drawbacks, the present inventor provides a handrail connector that can be reliably connected and can cope with expansion and contraction due to the temperature of the covering material as a result of intensive studies.

本発明請求項１記載の手摺用接続具は、芯材とこの芯材に被せられる被覆材からなる手摺部材を接続するための接続具であって、円筒面の一側が長手方向に亘って開口された被覆部とこの被覆部の内面壁に設けられた当接部からなりこの当接部が接続される手摺部材の芯材外壁に当接されるようになされ、被覆部内面が被覆材に当接されるようになされていることを特徴とするものであり、手摺用接続具を接続する手摺部材の芯材に固着することができるので、芯材と被覆剤の線膨張係数の違いによる変化に容易に対応することができるし、手摺部材と手摺用接続具の接着性に優れる。 The handrail connector according to claim 1 of the present invention is a connector for connecting a handrail member composed of a core material and a covering material covering the core material, wherein one side of the cylindrical surface is open over the longitudinal direction. And the abutting portion provided on the inner wall of the covering portion, and the abutting portion is brought into contact with the outer wall of the core member of the handrail member to which the abutting portion is connected. Since it can be fixed to the core material of the handrail member to which the handrail connector is connected, it depends on the difference in linear expansion coefficient between the core material and the coating agent. It can easily cope with changes, and has excellent adhesion between the handrail member and the handrail connector.

上述の如く、本発明請求項１記載の手摺用接続具は、芯材とこの芯材に被せられる被覆材からなる手摺部材を接続するための接続具であって、円筒面の一側が長手方向に亘って開口された被覆部とこの被覆部の内面壁に設けられた当接部からなりこの当接部が接続される手摺部材の芯材外壁に当接されるようになされ、被覆部内面が被覆材に当接されるようになされていることを特徴とするものであり、手摺用接続具を接続する手摺部材の芯材に固着することができるので、芯材と被覆剤の線膨張係数の違いによる変化に容易に対応することができるし、手摺部材と手摺用接続具の接着性に優れる。手摺用接続具は手摺部材の芯材に取り付けることができるので、被覆材の材質に係わらず強固に取り付けられる。 As described above, the handrail connector according to claim 1 of the present invention is a connector for connecting a core material and a handrail member made of a covering material covering the core material, and one side of the cylindrical surface is in the longitudinal direction. And a contact portion provided on the inner wall of the cover portion, the contact portion being in contact with the outer wall of the core member of the handrail member to which the contact portion is connected. Since it can be fixed to the core material of the handrail member to which the handrail connector is connected, the linear expansion of the core material and the coating material is achieved. It can easily cope with changes due to the difference in coefficients, and has excellent adhesion between the handrail member and the handrail connector. Since the handrail connector can be attached to the core material of the handrail member, it is firmly attached regardless of the material of the covering material.
