【発明の属する技術分野】
この出願の発明は、階段板固定構造に関するものである。さらに詳しくは、この出願の発明は、階段施工において蹴込板の踏板に対する固定および踏板の側板に対する固定を外観性および作業性良く行うことのできる、新しい階段板固定構造に関するものである。
【0002】
【従来の技術】
従来、階段の各段の施工については、たとえば図3に例示したように、踏板(1)の後部(11)上面に後嵌入溝(12)を設け、下端部(21)を嵌め込みさらに背面部(22)の後側からネジ釘打ちすることで蹴込板(2)を踏板(1)に対して立設且つ固定する構造(特許文献1参照)や、たとえば図4に例示したように、その後嵌入溝(12)を蹴込板(2)の立設に利用する他に、嵌入溝(12)内で側方に向けてネジ釘打ちすることで踏板(1)自体を側板(3)に対して固定する構造(特許文献2参照)が知られている。

【特許文献1】
特開平11−350691号公報
【特許文献2】
特開2000−17806号公報
【0004】
【発明が解決しようとする課題】
しかしながら、これら従来の固定構造では、後嵌入溝(12)における開口部分の溝後端縁(12a)の高さと溝前端縁(12b)の高さが同一で(図3参照)、単に後部(11)上面に溝を掘っただけのものとなっており、この嵌入溝(12)では、蹴込板(2)を踏板(1)にネジ釘打ち固定する際にネジ釘(4)(ネジ、ビス、釘など。以下同じ)がその打込角度によっては表面に露見する恐れがあり、外観性に不都合が考えられる。
【0005】
また一方で、踏板(1)を側板(3)にネジ釘打ち固定する場合には、ネジ釘(5)を深い後嵌入溝(12)内にて奥深くまで打込む必要があり(図4参照)、作業性に不都合が考えられる。
【0006】
そこで、この出願の発明は、以上のとおりの事情に鑑み、階段施工において蹴込板の踏板に対する固定および踏板の側板に対する固定を外観性および作業性良く行うことのできる、新しい階段板固定構造を提供することを課題としている。
【0007】
【課題を解決するための手段】
この出願の発明は、上記の課題を解決するものとして、第1には、階段板をネジ釘打ち固定する階段板固定構造であって、階段板である踏板の後部上面に溝後端縁が溝前端縁よりも低い後嵌入溝を設け、別の階段板である蹴込板の下端部を後嵌入溝に嵌め込み溝後端縁側からネジ釘打ちして踏板に固定したことを特徴とする階段板固定構造を提供する。
【0008】
また、この出願の発明は、第2には、前記後嵌入溝の後壁が傾斜面となっていることを特徴とする階段板固定構造、第3には、前記踏板の後部を後嵌入溝内にてネジ釘打ちして側板に固定したことを特徴とする階段板固定構造、第4には、前記踏板の前部上面に前嵌入溝を設け、踏板の後部を前嵌入溝内にてネジ釘打ちして側板に固定したことを特徴とする階段板固定構造、第5には、前記前嵌入溝が段鼻カバー取付用のものであることを特徴とする階段板固定構造、第6には、前記側板における蹴込板が沿う縦辺の下部に打込み用逃げ空間を設けたことを特徴とする階段板固定構造を提供する。
【0009】
【発明の実施の形態】
[第1の実施形態]
上記のとおりの特徴を有するこの出願の発明によれば、たとえば図1に例示したように、階段板である踏板(1)と蹴込板(2)について、踏板(1)の後部(11)上面に溝後端縁(12a)が溝前端縁(12b)よりも低い後嵌入溝(12)を設け、蹴込板(2)の下端部(21)を後嵌入溝(12)に嵌め込み溝後端縁(12a)側からネジ釘打ちして踏板(1)に固定するように構成することで、蹴込板(2)の踏板(1)に対する固定を外観性および作業性良く行うことが可能な階段板固定構造を実現できる。
【0010】
より具体的には、図1の実施形態では、まず、踏板(1)の後部(11)上面に、後嵌入溝(12)が、後端縁(111)よりある程度前側に寄った位置にて、後端縁(111)に沿って幅方向に形成されており、その溝後端縁(12a)側の後部(11)上面スペースが溝前端縁(12b)側の踏み面スペースよりも低くされて、溝後端縁(12a)の高さが溝前端縁(12b)の高さよりも低いものとなっている。
【0011】
これにおいて、蹴込板(2)は、その下端部(21)が後部(11)上面に嵌入され、さらに背面部(22)の後側つまり溝後端縁(12a)側からネジ釘打ちされて、踏板(1)に固定される。
【0012】
そして、後嵌入溝(12)の溝後端縁(12a)が溝前端縁(12b)よりも低く、その低い溝後端縁(12a)側からの打込みなので、ネジ釘(4)が表面側へ露見することが少なくなり、従来のような外観性についての不都合が解消されている。
【0013】
後嵌入溝(12)については、さらに、その後壁(121)を傾斜面とすることも考慮できる。より具体的には、後壁(121)を溝後端縁(12a)がある上部から溝底部に向けてテーパ−状に傾斜させて形成する。これにより、蹴込板(2)の下端部(21)を後嵌入溝(12)に嵌入させていくと、後嵌入溝(12)の前壁(122)側に寄せられて密着することとなり、蹴込板(2)と後嵌入溝(12)との表側からの隙間を無くせ、外観性のさらなる向上を図ることができるのである。
【0014】
[第2の実施形態]
またさらに、この出願の発明によれば、たとえば図2に例示したように、上述の後嵌入溝(12)内にて踏板(1)の後部(11)をネジ釘打ちして側板(3)に固定するように構成することで、踏板(1)の側板(3)に対する固定を外観性および作業性良く行うことが可能な階段板固定構造をも実現できる。
【0015】
より具体的には、図2の実施形態では、蹴込板(2)の下端部(21)のネジ釘打ち固定に加えて、同じ後嵌入溝(12)内にてネジ釘(5)を側方へ向けて打ち込み、踏板(1)の後部(11)を側板(3)に固定している。
【0016】
これにより、踏板(1)の後部(11)上面に設けた一つの後嵌入溝(12)にて、蹴込板(2)の下端部(21)の踏板(1)に対するネジ釘打ち固定と、踏板(1)の後部(11)の側板(3)に対するネジ釘打ち固定とを行うことができるので、その他の余計な溝等を設ける必要もなくなり、後部(11)の加工処理の簡易化や外観性がさらに向上される。
【0017】
そして、後嵌入溝(12)は上述したとおり溝後端縁(12a)の高さが低いので、溝後端縁(12a)側では溝深さが浅くなり、ネジ釘(5)の打込みが行い易く、さらに優れた作業性をも実現している。もちろんネジ釘(5)が表面に露見することもない。
【0018】
また、本実施形態では、側板(3)における蹴込板(2)が沿う縦辺(31)の下部に打込み用逃げ空間(32)が設けられてもいる。この打込み用逃げ空間(32)の存在により、ネジ釘(5)の打込みをより一層容易ならしめることができ、さらに一層優れた作業性が実現されているのである。
【0019】
[第3の実施形態]
ところで、上記各実施形態は踏板(1)の後部(11)でのネジ釘打ち固定についてのものであるが、踏板(1)についてはその前部(13)も側板(3)に固定することが当然好ましい。
【0020】
そこでさらに、この出願の発明によれば、図2に例示したように、踏板(1)の前部(13)上面に前嵌入溝(14)を設け、その前嵌入溝(14)内にて前部(13)を側板(3)に対してネジ釘打ち固定する構造をも実現される。図2の実施形態では、踏板(1)の前部(13)上面において、前嵌入溝(14)が、前端縁(131)よりある程度後側に寄った位置にて、前端縁(131)に沿って幅方向に形成されており、この前嵌入溝(14)内にて側方に向けてネジ釘(6)が打ち込まれている。
【0021】
また、本実施形態の前嵌入溝(14)は、溝前端縁(14b)が溝後端縁(14a)よりも低くなっており、低い縁が逆ではあるが前述の後嵌入溝(12)と同様に、ネジ釘(6)の打込みが行い易くなってもいる。
【0022】
このような前嵌入溝(14)は、本実施形態では、鼻段カバー(7)を取り付けるためにも使用されており、段鼻カバー(7)の引掛け片(71)が前嵌入溝(14)に嵌入され引っ掛け可能となっている。逆に言うと、段鼻カバー(7)取付用の前嵌入溝(14)を踏板(1)前部(13)のネジ釘打ち固定に用いてもよいのである。したがって、踏板(1)および段鼻カバー(7)別々の溝を設ける必要はなく、前部(13)の加工処理の簡易化や外観性の向上をさらに図ることができる。
【0023】
なお、段鼻カバー(7)以外にも、たとえば滑り止め部材等を取り付けるための溝として共用するなど、様々な共用バリエーションを考慮でき、いずれの場合にも上述と同様に踏板(1)の前部(13)の加工処理を容易ならしめ、踏板(1)および各種部材ともに作業性や外観性の向上を図ることができる。
【0024】
もちろん、この出願の発明は以上の実施形態に限定されるものではなく、細部については様々な態様が可能である。
【0025】
【発明の効果】
以上詳しく説明したとおり、この出願の発明によって、階段の各段の施工において蹴込板の踏板に対する固定および踏板の側板に対する固定を外観性および作業性良く行うことのできる、新しい階段板固定構造が提供される。
