Then, if the joint components 1 and 2 in which the concave fitting portion 5 and the convex fitting portion 6 are concavo-convexly fitted are rotated about the concavo-convex fitting, as shown in FIG. , Can be adjusted to a predetermined angle.

なお、前記凹状穴１１に設けられた当たり１２は、コイルバネ１５の弾力によって突出ている凸状嵌合部６の当たり１６が、この当たり１２に押圧されて、ぐらつかず安定した状態になるようにするためのものである。   The contact 12 provided in the concave hole 11 is such that the contact 16 of the convex fitting portion 6 protruding by the elasticity of the coil spring 15 is pressed by this contact 12 and does not wobble and is stable. Is to do.

以上のように構成したこの発明の手摺用連結具を、廊下や階段などに取り付ける手摺の角部などにおいて使用するには、次のようにして行う。   In order to use the handrail coupler of the present invention configured as described above in a corner portion of a handrail attached to a corridor, a staircase, or the like, it is performed as follows.

先ず、ジョイント構成体１、２を、それぞれの摺動平面３ａ、４ａを重ね合わせると共に凹状嵌合部５と凸状嵌合部６とを凹凸嵌合し、さらに凸状球面３ｂを凹状球面４ｃに、凸状球面４ｂを凹状球面３ｃにそれぞれ摺接させて、前記凹凸嵌合部を中心として回動可能に連結する。そして、手摺の取付現場において、一方のジョイント構成体１の連結筒部１ｂに一方の手摺パイプＰ1 を嵌合し、他方のジョイント構成体２の連結筒部２ｂに他方手摺パイプＰ2 を嵌合し、それぞれビス止めするなどして固定する。   First, the joint structures 1 and 2 are overlapped with the respective sliding planes 3a and 4a, and the concave fitting portion 5 and the convex fitting portion 6 are concavo-convexly fitted, and the convex spherical surface 3b is formed into the concave spherical surface 4c. Further, the convex spherical surface 4b is brought into sliding contact with the concave spherical surface 3c, respectively, and is connected so as to be rotatable about the concave-convex fitting portion. Then, at the installation site of the handrail, one handrail pipe P1 is fitted to the connecting cylinder portion 1b of one joint structure 1, and the other handrail pipe P2 is fitted to the connection cylinder portion 2b of the other joint structure 2. Fix them with screws.

次に、前記ジョイント構成体１、２を廊下や階段などの角部に対応するように、所定の角度に回動して調整し、図１に示したように、手摺パイプＰ1 、Ｐ2 に固着された支持具１８を、廊下や階段などの側壁に固定すればよい。   Next, the joint components 1 and 2 are adjusted by rotating to a predetermined angle so as to correspond to the corners such as the hallway and stairs, and fixed to the handrail pipes P1 and P2 as shown in FIG. What is necessary is just to fix the made support tool 18 to side walls, such as a hallway and a staircase.

したがって、この発明の手摺用連結具では、ジョイント構成体１、２の凹凸嵌合部が外部から見えず外観を損ねることがなく、しかも長年にわたって使用しているうちにその凹凸嵌合部が外部に突出してしまうようなことがなく、安全な状態で使用するすることができるものとなる。   Therefore, in the handrail connector according to the present invention, the concave and convex fitting portions of the joint components 1 and 2 are not visible from the outside, and the appearance is not impaired. Therefore, it can be used in a safe state.
