以下図面を参照して本発明の実施の形態について説明する。
図１は本発明に係る手摺材の連結構造を示すものである。図１において、符号１，２はそれぞれ手摺材を示す。これら手摺材１，２は円柱状または楕円柱状等の棒状に形成されており、その素材は木製、樹脂製等どのようなものでもよい。
一方の手摺材１の端面１ａは該手摺材１の長手方向に対して、所定の角度θだけ傾斜している。また、他方の手摺材２の端面２ａは該手摺材２の長手方向に対して、所定の角度θだけ傾斜している。 Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a connection structure of a handrail material according to the present invention. In FIG. 1, reference numerals 1 and 2 denote handrail materials, respectively. These handrail materials 1 and 2 are formed in a rod shape such as a columnar shape or an elliptical column shape, and the material thereof may be any material such as wooden or resin.
The end surface 1 a of one handrail material 1 is inclined by a predetermined angle θ with respect to the longitudinal direction of the handrail material 1. Further, the end surface 2 a of the other handrail material 2 is inclined by a predetermined angle θ with respect to the longitudinal direction of the handrail material 2.

手摺材１の端面１ａには孔１ｂが形成されており、手摺材２の端面２ａには孔２ｂが形成されている。これら孔１ｂ，２ｂは同径でかつ同深さのものであり、端面１ａ，２ａに対してそれぞれ直角に形成されている。また、孔１ｂ，２ｂは図１（ｃ）に示すように、端面１ａ，２ａを隙間Ｓを介して対向配置した際に同軸となるように形成されている。これら孔１ｂ，２ｂには連結材３が挿入されている。
連結材３は断面が孔１ｂ，２ｂとほぼ等しく形成された円柱状のものであり、例えば、透明なアクリル樹脂によって形成されている。連結材３の長さは、一方の手摺材１の端面１ａに形成された孔１ｂと他方の手摺材２の端面２ａに形成された孔２ｂの深さの合計長さより前記隙間Ｓの長さの分だけ長くなっている。例えば隙間Ｓが３ｍｍであるとすると、連結材３の長さは８３ｍｍ、孔１ｂ，２ｂのそれぞれの長さは４０ｍｍとなっている。 A hole 1 b is formed in the end surface 1 a of the handrail material 1, and a hole 2 b is formed in the end surface 2 a of the handrail material 2. These holes 1b and 2b have the same diameter and the same depth, and are formed at right angles to the end faces 1a and 2a, respectively. Moreover, the holes 1b and 2b are formed so as to be coaxial when the end faces 1a and 2a are opposed to each other with a gap S as shown in FIG. A connecting member 3 is inserted into the holes 1b and 2b.
The connecting member 3 has a cylindrical shape whose cross section is substantially equal to the holes 1b and 2b, and is formed of, for example, a transparent acrylic resin. The length of the connecting material 3 is the length of the gap S based on the total length of the hole 1b formed in the end surface 1a of one handrail material 1 and the depth of the hole 2b formed in the end surface 2a of the other handrail material 2. It is longer by For example, if the gap S is 3 mm, the length of the connecting member 3 is 83 mm, and the lengths of the holes 1b and 2b are 40 mm.

そして、手摺材１，２は、図１（ｃ）に示すように、それらの端面１ａ，２ａに形成された孔１ｂ，２ｂに挿入された連結材３によって、所定の隙間Ｓを介して連結されている。また、連結材３は孔１ｂ，２ｂの底面に当接するまで、これら孔１ｂ，２ｂに挿入されている。   And the handrail materials 1 and 2 are connected through a predetermined gap S by connecting members 3 inserted into holes 1b and 2b formed in the end faces 1a and 2a, as shown in FIG. Has been. Further, the connecting member 3 is inserted into the holes 1b and 2b until they contact the bottom surfaces of the holes 1b and 2b.

次に、手摺材１，２を連結材３を使用して連結する方法について説明する。
まず、図２（ａ）に示すように、一方の手摺材１を階段室等に形成された壁に、ブラケット４によって水平に固定する。ブラケット４を壁に固定する場合、該ブラケット４からビス５を壁にねじ込むことにより行う。なお、ブラケット４は手摺材１の長手方向に所定間隔で複数取付られている。
次に、手摺材１の端面１ａに形成された孔１ｂに連結材３をその端部が孔１ｂの底面に当接するまで挿入する（図１（ｂ）参照）。
次に、他方の手摺材２にブラケット４，４を取付け、該手摺材２を、その端面２ａが手摺材１の端面１ａに略平行となるようにして近付け、その後、図２（ｂ）に示すように、手摺材１の端面１ａか突出している連結材３に、手摺材２の端面２ａに形成された孔２ｂを外挿する。つまり、連結材３を孔２ｂに挿入する。この場合、連結材３の端部が孔２ｂの底面に当接するまで挿入する（図１（ｃ）参照）。これによって、手摺材１，２の端面１ａ，２ｂ間に所定の隙間Ｓを確保できる。
次に、他方の手摺材２のブラケット４，４からビス５を壁にねじ込むことによって、手摺材２を階段の傾斜方向（水平方向に対して傾斜角θ）と略平行となるようにして、壁に固定する。この固定は、手摺材１，２の端面１ａ，２ａが平行となるように調整しながら行う。 Next, a method of connecting the handrail materials 1 and 2 using the connecting material 3 will be described.
First, as shown in FIG. 2A, one handrail material 1 is horizontally fixed by a bracket 4 to a wall formed in a staircase or the like. When the bracket 4 is fixed to the wall, the screws 5 from the bracket 4 are screwed into the wall. A plurality of brackets 4 are attached at predetermined intervals in the longitudinal direction of the handrail material 1.
Next, the connecting member 3 is inserted into the hole 1b formed in the end surface 1a of the handrail material 1 until the end portion abuts against the bottom surface of the hole 1b (see FIG. 1B).
Next, brackets 4 and 4 are attached to the other handrail material 2, and the handrail material 2 is brought close to the end surface 1a of the handrail material 1 so that the end surface 2a thereof is substantially parallel to the handrail material 1, and then to FIG. As shown, a hole 2 b formed in the end surface 2 a of the handrail material 2 is extrapolated to the connecting material 3 protruding from the end surface 1 a of the handrail material 1. That is, the connecting material 3 is inserted into the hole 2b. In this case, it inserts until the edge part of the connection material 3 contact | abuts to the bottom face of the hole 2b (refer FIG.1 (c)). Thereby, a predetermined gap S can be secured between the end faces 1a and 2b of the handrail materials 1 and 2.
Next, the screw 5 is screwed into the wall from the brackets 4 and 4 of the other handrail material 2 so that the handrail material 2 is substantially parallel to the inclination direction of the stairs (inclination angle θ with respect to the horizontal direction) Secure to the wall. This fixing is performed while adjusting the end faces 1a and 2a of the handrail materials 1 and 2 to be parallel.

以上本実施の形態によれば、一方の手摺材１の端面１ａと他方の手摺材２の端面２ａとにそれぞれ形成された孔１ｂ，２ｂに挿入された連結材３によって、手摺材１，２どうしが隙間Ｓを介して連結されているので、連結に要する部品は連結材３のみでよく、従来に比して部品点数を少なくできる。また、連結材３は手摺材１，２の表面側に露出することなく、手摺材１，２の端面１ａ，２ａ間の隙間Ｓから若干見える程度であり、しかも連結材３は透明であるので、手摺材の連結構造としてデザイン上もスッキリしたものとなる。
また、連結材３を挿入する孔１ｂ，２ｂが手摺材１，２の端面１ａ，２ａに対して直角に形成されているので、手摺材１，２どうしをどのような角度をもって連結する場合においても、孔１ｂ，２ｂを容易に形成することができる。つまり、階段の傾斜が変化しても、手摺材１，２の端面１ａ，２ａの角度θを変更して、この端面１ａ，２ａに孔１ｂ，２ｂを容易に形成できる。 As described above, according to the present embodiment, the handrail materials 1, 2 are connected by the connecting members 3 inserted into the holes 1b, 2b formed in the end surface 1a of one handrail material 1 and the end surface 2a of the other handrail material 2, respectively. Since the parts are connected through the gap S, the parts required for the connection need only be the connecting material 3, and the number of parts can be reduced as compared with the conventional case. Further, the connecting material 3 is not exposed on the surface side of the handrail materials 1 and 2, and is only slightly visible from the gap S between the end surfaces 1 a and 2 a of the handrail materials 1 and 2, and the connecting material 3 is transparent. As a connecting structure for handrails, the design will be refreshed.
In addition, since the holes 1b and 2b for inserting the connecting material 3 are formed at right angles to the end surfaces 1a and 2a of the handrails 1 and 2, when connecting the handrail materials 1 and 2 at any angle, In addition, the holes 1b and 2b can be easily formed. In other words, even if the slope of the stairs changes, the holes 1b and 2b can be easily formed in the end surfaces 1a and 2a by changing the angle θ of the end surfaces 1a and 2a of the handrail materials 1 and 2.

また、一方の手摺材１に他方の手摺材２を連結する場合に、一方の手摺材１の端面１ａに対して、他方の手摺材２の端面２ａが平行になるようにして、該他方の手摺材２を一方の手摺材１に近付けて、連結材３を介して連結できるので、手摺材１，２どうしを正確に位置決めして連結できる。
さらに、一方の手摺材１の端面１ａに形成された孔１ｂと他方の手摺材２の端面２ａに形成された孔２ｂとに連結材３をこれら孔１ｂ，２ｂの底まで挿入することによって、手摺材１，２どうしを所定の隙間をもって確実に連結できる。 When connecting the other handrail material 2 to one handrail material 1, the end surface 2a of the other handrail material 2 is parallel to the end surface 1a of the one handrail material 1, Since the handrail material 2 can be brought close to one handrail material 1 and can be connected via the connecting material 3, the handrail materials 1 and 2 can be accurately positioned and connected.
Further, by inserting the connecting material 3 into the hole 1b formed in the end surface 1a of one handrail material 1 and the hole 2b formed in the end surface 2a of the other handrail material 2 to the bottom of these holes 1b, 2b, The handrail materials 1 and 2 can be reliably connected with a predetermined gap.

なお、本実施の形態では、手摺材１に手摺材２を傾斜させて連結する場合について説明したが、本発明では、手摺材どうしを直線状に連結する場合でも連結材３を使用して行うことができる。また、連結材３を複数本としてもよい。   In this embodiment, the case where the handrail material 2 is connected to the handrail material 1 while being inclined has been described. However, in the present invention, the connection material 3 is used even when the handrail materials are connected linearly. be able to. Further, a plurality of connecting members 3 may be provided.
