Description

【０００１】
【発明の属する技術分野】
本発明は、主として住宅用に使用され、両側または片側に手摺を有し、前記手摺は、下桟と上桟との間に複数の手摺子を設けてなる階段に関する。
【０００２】
【従来の技術】
住宅のバルコニーに上がるための階段や、二階の玄関や勝手口に上がるための階段等は、左右の側板上に手摺を有する。この手摺は、下桟の上面に立上部を設け、該立上部に手摺子（格子）の側面を重ねて結合する構造を有する。このような階段においては、手摺子は鉛直に設置される。
【０００３】
【発明が解決しようとする課題】
このような階段において、下桟は傾斜して設置され、手摺子は鉛直に設置されるので、下桟の立上部と手摺子と間の上側のコーナー部においては、側方から見て両者のなす角度が鋭角となる。このように、前記コーナー部が鋭角をなすため、昇降の際に手指をその鋭角状のコーナー部に入れ込むおそれがある。階段が急になるほど前記コーナー部の角度が小さくなるため、前記コーナー部にますます手指を入れ込み怪我をするおそれがある。
【０００４】
本発明は、上記問題点に鑑み、手摺の下桟と手摺子との間の上側の鋭角をなすコーナー部に手指が入り込むことによる怪我を防止しうる構造の階段を提供することを目的とする。
【０００５】
【課題を解決するための手段】
請求項１の階段は、階段の両側または片側に手摺を有し、
前記手摺は、下桟と上桟との間に複数の手摺子を有し、
前記下桟は基部に上方に立ち上がった立上部を有し、
前記手摺子の下端と前記立上部とを重ねてなり、
前記手摺子と前記立上部の上辺部とによって形成される鋭角をなすコーナー部に手指の入り込みを防ぐ塞ぎ部材を設けた
ことを特徴とする。
【０００６】
このように、手摺子と下桟の立上部との間のコーナー部に塞ぎ部材を設けることにより、コーナー部が塞がれ、手指の入り込みが防止される。
【０００７】
請求項２の階段は、請求項１において、
前記塞ぎ部材に前記手摺子側面を一部覆う延出部を一体に設けた
ことを特徴とする。
【０００８】
このように、塞ぎ部材に延出部を設ければ、コーナー部において、階段の設置角度の如何に係らず、塞ぎ部材の側部の隙間が延出部で覆われる。
【０００９】
【発明の実施の形態】
図１は本発明による階段の一実施の形態を示す分解斜視図、図２は該階段の部分斜視図、図３は該階段の踏板の取付け構造を示す斜視図である。図１ないし図３において、１は梯子の側板、２は左右の側板１間に架設される踏板、３は側板２上に設けられる手摺である。手摺３は上桟４と下桟５と両者間に設けられる手摺子６とからなる。前記側板１、踏板２、上桟４、下桟５、手摺子６はアルミニウム合金形材からなる。
【００１０】
本実施の形態においては、この階段は設置する場所の広さ等に合わせて側板１の角度が調整できるようにするため、踏板２は側板１に対して上面の角度が変更できるように構成される。このような踏板２の角度が調整可能となるように、図３に示す調整機構が設けられる。すなわち、側板１は内側の面に矢印Ａに示すように、長手方向に移動可能に可動板７を有し、踏板２の下面の両端にはブラケット８を固定具９により固定し、ブラケット８の一端側の孔にボルト１０を挿通して可動板７に収容したナット（図示せず）に螺合して固定し、ブラケット８の他端側は、ブラケット８に設けた長孔１１に挿通するボルト１２を側板１に収容したナット（図示せず）に螺合して固定する構造を有する。このため、側板１の設置角度に合わせて可動板７を矢印Ａの方向に移動させ、踏板２の上面が水平になったところでタッピングねじ等の固定具１４によって可動板７を側板１に固定することにより、階段の設置角度に対応して踏板２を水平に設置することができる。
【００１１】
また、図２に示すように、下桟５は、側板１の上面に嵌合される断面形状が逆Ｕ字形の基部５ａを有し、該基部５ａをタッピングねじ等の固定具１５により側板１に固定される。該下桟５の基部５ａの上面には一対の立上部５ｂを有し、これらの立上部５ｂに手摺子６の下端側面を重ね、ボルトやタッピングねじ等の固定具１６で結合することにより、手摺子６は下桟５に対して固定具１６を中心に回動可能に結合される。本実施の形態においては、立上部５ｂ、５ｂ間に下桟６の下端を嵌合して固定しているが、立上部５ｂは１条のみ設けてもよい。
【００１２】
手摺子６の上端は、上桟４に対し、ボルトやタッピングねじ等の固定具１７により結合され、手摺子６は上桟４に対して固定具１７を中心に回動自在である。このため、階段の設置角度、すなわち側板１の設置角度に係らず、手摺子６が常に鉛直になるように設置することができる。
【００１３】
なお、側板１の上端はブラケット（図示せず）を介してバルコニーのフレームや建物の躯体に結合される。また、上桟４上には笠木が取付けられ、その上端は躯体（図示せず）にブラケットを介して結合されるが、図示を省略している。また、その笠木の下端は別の支柱（図示せず）を介して側板１の下部に固定される。また、側板１の下端には角度調整自在にアンカー（図示せず）が取付けられ、そのアンカーが地面の受部に固定される。
【００１４】
前記下桟５と手摺子６との間の上側のコーナー部１８は側方から見て鋭角をなす。このため、この上側のコーナー部１８、すなわち立上部５ｂの上辺部と手摺６との間の鋭角状のコーナー部１８に手指が入り込むおそれがある。このため、本実施の形態においては、図４（Ａ）に示すようなコーナー部１８の形状に対応した側面形状が略三角形の塞ぎ部材１９を、図４（Ｂ）に示すようにコーナー部１８に設ける。本実施の形態においては、塞ぎ部材１９は樹脂成形材からなる（木製あるいは金属製でもよい）ものを、立上部５ｂ、５ｂと手摺子６との間に嵌合することにより取付けられた構造を示している。該塞ぎ部材１９の取付け構造としては、塞ぎ部材１９を下桟５や手摺子６の孔や切欠部等に弾発的に係止する構造や、コーナー部１８への接着、あるいは固定具による固定構造を採用することもできる。
【００１５】
このように、手摺６と立上部５ｂの上辺部との間の側方から見て鋭角をなすコーナー部１８を塞ぎ部材１９により塞げば、この鋭角状のコーナー部１８に過誤により手指を入れ込むことを防ぐことができる。
【００１６】
図５（Ａ）は本発明の塞ぎ部材の他の実施の形態を示しており、本実施の形態においては、種々のコーナー角度に兼用できるように、塞ぎ部材２０の上部に、手摺子６の下端部の側面を覆う延出部２０ａを設けている。なお、該延出部２０ａは、塞ぎ部材２０の両側に設けるのではなく、踏板２側のみの片側に設けてもよい。
【００１７】
このような延出部２０ａを設ければ、図５（Ｂ）、（Ｃ）に示すように、ほぼ中程度の傾斜角度に階段において、延出部２０ａを手摺子６の側面にあて、下部を立上部５ｂ間に嵌合した状態において、コーナー部１８を塞ぐことができるのみならず、図５（Ｄ）に示すように、比較的角度が緩やかな場合であっても、図５（Ｅ）示すように、角度が急峻な場合であっても、いずれも塞ぎ部材２０の側面に隙間が生じることなく、コーナー部１８を塞ぐことができ、１つの部品で種々の角度の階段に対応でき、また、傾斜角度調整可能な階段において、種々の設置角度に対応することができ、経済化が達成できる。
【００１８】
本発明を実施する場合、手摺は階段の片側にのみ設けてもよい。また、本発明は、階段の傾斜角度が固定となる構造のものや、下桟５が側板１に一体に形成される場合にも適用できる。さらに本発明を実施する場合、側板１、踏板２、上桟４、下桟５、手摺子６等の具体的形状、構造は種々に変更、付加することができる。
【００１９】
【発明の効果】
請求項１によれば、手摺子と下桟の立上部の上辺部との間の鋭角状のコーナー部を塞ぐ塞ぎ部材を設けたので、このコーナー部に手指が入り込み怪我をするおそれがなくなる。
【００２０】
請求項２によれば、請求項１において、前記塞ぎ部材に前記手摺子側面を一部覆う延出部を一体に設けたので、コーナー部において、階段の設置角度の如何に係らず、塞ぎ部材の側面に隙間が延出部で覆われる。このため、１種の塞ぎ部材で種々の設置角度の階段に対応でき、また、角度調整可能な階段における種々の設置角度に対応することができ、経済化が達成できる。

[Means for Solving the Problems]
The stairs of claim 1 have handrails on both sides or one side of the stairs,
The handrail has a plurality of handrails between a lower rail and an upper rail,
The lower rail has a raised portion that rises upward at the base,
Overlapping the lower end of the handrail and the upright,
A closing member for preventing a finger from entering is provided at an acute corner formed by the handrail and the upper side of the upright portion.
[0006]
Thus, by providing a closing member at the corner portion between the handrail and the upright portion of the lower rail, the corner portion is blocked and the entry of fingers is prevented.
[0007]
The staircase of claim 2 is the method of claim 1,
An extending portion that partially covers the side surface of the balustrade is provided integrally with the closing member.
[0008]
Thus, if the extending part is provided in the closing member, the gap on the side part of the closing member is covered with the extending part in the corner part regardless of the installation angle of the stairs.
[0009]
