Description

【０００１】
【発明の属する技術分野】
この発明は、手摺用継手、特に、支柱の両側にビームが、支柱と直交する水平面内において角度をつけて固定されているときに、真上から見て手摺とビームとが重なり合うように、支柱の頂部に手摺を固定することができる手摺用継手に関するものである。
【０００２】
【従来の技術】
従来、支柱の両側にビームを、支柱と直交する水平面内において角度調整可能に固定するには、次のようにして行っていた。即ち、図１７に示すように、支柱１の側面に半球状部材３を当てがい、半球状部材３に半割り継手部材４を半球状座金５およびボルト６によって固定し、半割り継手部材４にビーム２の端部をボルト７によって固定する。
【０００３】
半割り継手部材４のボルト挿通孔４Ａは、バカ孔状に形成されているので、所定角度範囲内において、支柱１に対するビーム２の固定角度を調整することができる。
【０００４】
一方、支柱の頂部に手摺を、支柱と直交する水平面内において角度調整可能に固定するには、次のようにして行っていた。即ち、図１７に示すように、支柱１の頂部に連結金物８をボルト９によって固定し、連結金物８に形成された受け板１０に端部金物１１および手摺１２をボルト１３によって固定する。端部金物１１の連結端は、半円柱状に形成され、ボルト１４によって角度調整可能に連結されている。
【０００５】
ボルト１４は、支柱１の中心軸線と合致しているので、手摺１２の固定角度は、支柱１の中心軸線を中心として調整することができる。
【０００６】
【発明が解決しようとする課題】
しかしながら、上述した従来技術は、次のような問題があった。即ち、ビーム２は、図１８に示すように、支柱１の外周面を通る軸線（ｌ1 ）を中心として回動する。これに対して、手摺１２は、支柱１の中心軸線（ｌ2 ）を中心として回動する。このように、ビーム２と手摺１２との回動中心軸線が異なるので、支柱１の真上から見た場合、手摺とビームとが重なり合わず、外観が悪い。
【０００７】
従って、この発明の目的は、支柱の両側にビームが、支柱と直交する水平面内において角度をつけて固定されているときに、真上から見て手摺とビームとが重なり合うように、支柱の頂部に手摺を固定することができる手摺用継手を提供することにある。
【０００８】
【課題を解決するための手段】
請求項１記載の発明は、支柱の頂部に一対の手摺の各々の端部を、前記支柱の軸線と直交する面内において角度調整可能に固定するための手摺用継手において、前記支柱の前記頂部に固定される連結金物と、前記手摺の前記端部に固定される、支柱側端面が球面状に形成された端部金物と、前記連結金物と前記端部金物との間に固定され、前記連結金物に形成された凹陥部内に嵌め込まれる、上面が前記端部金物の下面と密着するように曲面に形成された円形状台座金物と、前記端部金物を前記台座金物を介して前記連結金物上に固定するためのボルトとからなり、前記ボルトの中心軸線間の距離は、前記支柱の外径寸法と等しいことに特徴を有するものである。
【０００９】
【発明の実施の形態】
次に、この発明の手摺用継手の一実施態様を、図面を参照しながら説明する。図１は、この発明の手摺用継手を示す斜視図、図２は、この発明の手摺用継手を示す平面図、図３は、この発明の手摺用継手を示す正面図、図４は、この発明の手摺用継手を示す側面図、図５は、この発明の手摺用継手の連結金物を示す斜視図、図６は、この発明の手摺用継手の連結金物を示す平面図、図７は、この発明の手摺用継手の連結金物を示す正面図、図８は、この発明の手摺用継手の連結金物を示す側面図、図９は、この発明の手摺用継手の端部金物を示す斜視図、図１０は、この発明の手摺用継手の端部金物を示す平面図、図１１は、この発明の手摺用継手の端部金物を示す正面図、図１２は、この発明の手摺用継手の端部金物を示す側面図、図１３は、この発明の手摺用継手の台座金物を示す斜視図、図１４は、この発明の手摺用継手の台座金物を示す平面図、図１５は、この発明の手摺用継手の台座金物を示す正面図、図１６は、この発明の手摺用継手の台座金物を示す側面図である。
【００１０】
図１から図１６において、１５は、支柱１の球面状頂部にボルト止めされる連結金物である。連結金物１５は、図５から図８に示すように、支柱１の球面状頂部に嵌まり込む球面状下面１５Ａ、支柱１にボルト止めするためのボルトの挿通孔１５Ｂ、および、挿通孔１５Ｂの両側に後述する台座金物が嵌合する一対の円形状凹陥部１５Ｃが形成されている。凹陥部１５Ｃの底部には、後述する端部金物および前記台座金物を挿通してねじ込まれるボルト１６のねじ孔１５Ｄが形成されている。ねじ孔１５Ｄの中心軸線間の距離（Ｌ）は、支柱１の外径寸法と等しい。
【００１１】
１７は、手摺１２の端部に固定される端部金物である。端部金物１７は、図９から図１２に示すように、手摺１２にボルト止めするためのボルトのねじ孔１７Ａ、および、ボルト１６の挿通孔１７Ｂが形成されている。端部金物１７は、支柱側端面は、手摺１２を回動させたときに、互いに干渉しないように球面状に形成されている。
【００１２】
１８は、連結金物１５の凹陥部１５Ｃ内に嵌め込まれる円形状台座金物である。台座金物１８は、図１３から図１６に示すように、ボルト１６の挿通孔１８Ａが形成され、上面は、端部金物１７の下面と密着するように、曲面に形成されている。
【００１３】
このように構成されている、この発明の手摺用継手によれば、以下のようにして、支柱１の頂部に手摺２が固定される。
先ず、支柱１の頂部に連結金物１５をボルト止めする。次に、連結金物１５の凹陥部１５Ｃ内に台座金物１８を嵌め込む。そして、台座金物１８上に、手摺１２をボルト止めした端部金物１７を乗せ、ボルト１６を端部金物１７のボルト挿通孔１７Ｂおよび台座金物１８のボルト挿通孔１８Ａ内に挿通して、連結金物１５のねじ孔１５Ｄ内にねじ込む。
【００１４】
ボルト１６の中心軸線間の距離は、支柱１の外径寸法と等しいので、手摺１２は、支柱１の外周面を通る軸線を中心として角度調整可能に取り付けられる。従って、図１７に示すように、半球状部材３を使用してビーム２を支柱１に固定する場合においても、真上から見て手摺１２とビーム２とが重なり合うように、手摺１２を支柱１の頂部に固定することができる。
【００１５】
【発明の効果】
以上説明したように、この発明によれば、支柱の頂部に固定する一対の手摺の固定軸間の距離を支柱の外径寸法と一致させることによって、支柱の両側にビームが、支柱と直交する水平面内において角度をつけて固定されているときに、真上から見て手摺とビームとが重なり合うように、支柱の頂部に手摺を固定することができるといった有用な効果がもたらされる。

BACKGROUND OF THE INVENTION
The present invention relates to a handrail joint, in particular, a strut so that the handrail and the beam overlap each other when viewed from directly above when the beam is fixed on both sides of the strut at an angle in a horizontal plane orthogonal to the strut. It is related with the joint for handrails which can fix a handrail to the top part.
[0002]
[Prior art]
Conventionally, in order to fix the beam on both sides of the column so that the angle can be adjusted in a horizontal plane perpendicular to the column, the beam is fixed as follows. That is, as shown in FIG. 17, the hemispherical member 3 is applied to the side surface of the support column 1, and the half joint member 4 is fixed to the hemispherical member 3 by the hemispherical washer 5 and the bolt 6. The end of the beam 2 is fixed by a bolt 7.
[0003]
Since the bolt insertion hole 4A of the half joint member 4 is formed in a fool hole shape, the fixed angle of the beam 2 with respect to the column 1 can be adjusted within a predetermined angle range.
[0004]
On the other hand, in order to fix the handrail to the top of the column so that the angle can be adjusted in a horizontal plane orthogonal to the column, the following method is used. That is, as shown in FIG. 17, the connecting hardware 8 is fixed to the top of the column 1 by the bolts 9, and the end hardware 11 and the handrail 12 are fixed to the receiving plate 10 formed on the connecting hardware 8 by the bolts 13. The connecting end of the end hardware 11 is formed in a semi-cylindrical shape and is connected by a bolt 14 so that the angle can be adjusted.
[0005]
Since the bolt 14 coincides with the center axis of the column 1, the fixing angle of the handrail 12 can be adjusted around the center axis of the column 1.
[0006]
[Problems to be solved by the invention]
However, the above-described prior art has the following problems. That is, the beam 2 rotates about an axis (l 1 ) passing through the outer peripheral surface of the column 1 as shown in FIG. On the other hand, the handrail 12 rotates around the central axis (l 2 ) of the column 1. Thus, since the rotation center axis lines of the beam 2 and the handrail 12 are different, the handrail and the beam do not overlap with each other when viewed from directly above the support column 1, and the appearance is poor.
[0007]
Therefore, the object of the present invention is to make the top of the column so that the handrail and the beam overlap when viewed from directly above when the beam is fixed at an angle in a horizontal plane orthogonal to the column on both sides of the column. An object of the present invention is to provide a handrail joint capable of fixing a handrail.
[0008]
[Means for Solving the Problems]
The invention according to claim 1 is a handrail joint for fixing the end portions of a pair of handrails to the top portion of the support column so that the angle can be adjusted in a plane orthogonal to the axis of the support column. in the coupling hardware to be fixed, is fixed to the end portion of the handrail, and the end fittings which strut end surface is formed in a spherical shape, is fixed between the end fittings and the connecting hardware, the coupling is fitted into recessed in portion formed in the hardware, a circular pedestal hardware formed into a curved surface so that the upper surface is in close contact with the lower surface of said end fittings, the connection hardware to the end fittings through the base hardware It is characterized by comprising a bolt for fixing on top , and the distance between the central axes of the bolts being equal to the outer diameter of the column.
