【０００３】
【従来技術の欠点】
前記従来の手摺連結具には以下の如き欠点があった。
第１部材と第２部材とが連結ピンで折り曲げ自在に連結されたものであったため、連結ピンの軸心に直交する方向（上下方向）にしか折り曲げ出来なかったので、連結される手摺が施工誤差等によって平面から見て一直線に並ばない場合に手摺の連結が困難又は出来ないという欠点があった。
【０００４】
【課題を解決するための手段】
本発明は前記欠点を解消するために以下の如き手段を採用した。
請求項１の発明は、手摺が連結される第１部材と、手摺が連結される第２部材とを有し、第１部材又は第２部材の一方が球面の一部からなる中空状の凸部材を有し、同他方が凸部材に整合嵌合する中空状の凹部材を有し、凸部材と凹部材とが、凸部材及び凹部材に形成された各貫通孔に上下・左右動自在に嵌められた連結ピンによって連結されて任意の方向に折り曲げ自在に嵌合され、該連結ピンは一端部に凸部材の内周面に摺接する抜け止め部材を備え、他端部に凹部材の内周面に摺接する抜け止め部材を備えているものである。
請求項２の発明は、前記連結ピンが凸部材及び凹部材のいずれに対しても上下方向に所定長さだけ上下動自在となされて第１部材と第２部材とが相互に所定角度をなすように折り曲げられるようになされている請求項１記載のものである。
請求項３の発明は、前記第１部材及び第２部材に手摺の端部が嵌まる嵌合凹所が形成され、この嵌合凹所の奥部に手摺の端面が当たるストッパーが設けられている請求項１又は２に記載のものである。
【０００５】
【発明の効果】
本発明は前記した如き構成によって以下の如き効果を奏する。
（１）請求項１の発明によれば、凸部材と凹部材とが、換言すれば、第１部材と第２部材とが任意の方向に折り曲げ自在に連結されているので、連結される手摺が施工誤差等によって平面から見て一直線に並ばない場合にも、手摺を連結することが出来る。
（２）請求項２の発明によれば、連結ピンが凸部材及び凹部材のいずれに対しても上下方向に所定長さだけ上下動自在となされているので、連結ピンが凸部材又は凹部材のいずれか一方にのみ上下方向に所定長さだけ上下動自在となされている場合に比較して、凸部材と凹部材との嵌合の割合を少なくして、第１部材と第２部材とが相互に所定角度をなすように折り曲げることが出来る。
（３）請求項３の発明によれば、手摺を嵌合凹所に嵌めると共に手摺をストッパーに押し当てさえすれば、手摺と第１部材との相対位置及び手摺と第２部材との相対位置が自動的に定まるので、組み立てが行ないやすい。
【０００６】
【発明の実施の形態】
以下に、２つの発明の実施の形態を説明する。
なお、これらの説明において同一の部材は同一の符号で示す。
【０００７】
［発明の第１の実施の形態］（図１参照）
なお、この説明において、上とは図１上側を、下とは同図下側をいい、左とは図１紙面表側を、右とは同裏側をいう。
【０００８】
手摺連結具１は、任意断面、例えば断面円形の手摺２が連結される第１部材３と、手摺２が連結される第２部材４とを有している。
第１部材３又は第２部材４の一方、具体的には第１部材３が、球面の一部からなる凸部材６を有し、同他方、具体的には第２部材４が、凸部材６に整合嵌合する凹面を有する凹部材７を有している。前記凸部材６と凹部材７とが以下に詳述するような手段によって任意の方向に折り曲げ自在に嵌合・連結されている。
【０００９】
中空状の凸部材６に貫通孔９が形成され、この貫通孔９に凸部材６の内面に摺接する抜け止め部材１０を有する連結ピン１１が上下・左右動自在に嵌められている。貫通孔９に連結ピン１１が上下・左右動自在に嵌められているとは、連結ピン１１の軸部の直径ｄより、貫通孔９の上下長さ及び貫通孔９の左右長さが長いことを意味する。
前記連結ピン１１の頭部１１ａ（先端部）は、中空状の凹部材７に形成された貫通孔１３に上下・左右動自在に嵌められている。貫通孔１３に連結ピン１１の頭部１１ａが上下・左右動自在に嵌められているとは、頭部１１ａの直径Ｄより、貫通孔１３の上下長さ及び貫通孔１３の左右長さが長いことを意味する。

A through hole 9 is formed in the hollow convex member 6, and a connecting pin 11 having a retaining member 10 slidably contacting the inner surface of the convex member 6 is fitted in the through hole 9 so as to be movable up and down and left and right. The fact that the connecting pin 11 is fitted in the through hole 9 so as to be movable up and down and left and right is that the vertical length of the through hole 9 and the left and right length of the through hole 9 are longer than the diameter d of the shaft portion of the connecting pin 11. Means.
A head portion 11a (tip portion) of the connecting pin 11 is fitted in a through hole 13 formed in the hollow concave member 7 so as to be movable up and down and left and right. The fact that the head portion 11a of the connecting pin 11 is fitted in the through hole 13 so as to be movable up and down and left and right means that the vertical length of the through hole 13 and the left and right length of the through hole 13 are longer than the diameter D of the head portion 11a.
