以下、本発明の実施の形態を図面に基づいて説明する。この手摺は、階段部に設置して用いられるものであり、図１に示すように、支柱４ａ，４ｂ，４ｃ，４ｄ，４ｅと、笠木５と、中桟（横材）１を備える。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The handrail is used by being installed on a staircase, and includes support columns 4a, 4b, 4c, 4d, and 4e, a headboard 5 and an intermediate beam (cross member) 1 as shown in FIG.

支柱は、階段の各段に１本又は複数本立設してあり、階段の下側に立設したものから順に４ａ〜４ｅとなっていて、上端の高さ順に並んでいる。すなわち、支柱４ａと支柱４ｂは同じ段に立設してあるが、支柱４ｂの方が長いので上端の高さが高い。また、支柱４ｂと支柱４ｃは同じ長さであるが、支柱４ｃの方が上の段に立設してあるので上端の高さが高い。同じく、支柱４ｃと支柱４ｄは同じ長さであるが、支柱４ｄの方が上の段に立設してあるので上端の高さが高い。そして、支柱４ｅは支柱４ｄよりも上の段に立設してあるが、支柱４ｅの方が短く、支柱４ｄと支柱４ｅの上端の高さは同じである。なお、隣接する支柱間（支柱４ｄと支柱４ｅを除く）の上端の高さの差は全て等しく、階段の１段の高さと同じである。 One or a plurality of support columns are erected on each step of the stairs, and the columns are 4a to 4e in order from the erection on the lower side of the stairs, and are arranged in the order of the height of the upper end. In other words, the support column 4a and the support column 4b are erected on the same stage, but the support column 4b is longer, so the height of the upper end is higher. Moreover, although the support | pillar 4b and the support | pillar 4c are the same length, since the support | pillar 4c is standingly arranged in the upper stage, the height of an upper end is high. Similarly, the column 4c and the column 4d have the same length, but the column 4d is erected on the upper stage, so that the height of the upper end is high. The column 4e is erected above the column 4d, but the column 4e is shorter and the upper ends of the columns 4d and 4e have the same height. Note that the difference in height between the upper ends of adjacent struts (excluding the struts 4d and 4e) is all equal and the same as the height of one step of the stairs.

笠木５は、手摺の上端部に取り付けた水平方向に延びる部材である。上記のとおり、支柱は上端の高さ順に並んでおり、隣接する支柱の上端の高さが異なるので、笠木５は、隣接する支柱間において、一端を低い方の支柱の上端に取り付けてあり、他端を高い方の支柱の側面に取り付けてある。ここで、一端側は階段の降り側となり、他端側は階段の昇り側となる。すなわち、支柱４ａと支柱４ｂにおいて、笠木５は降り側の支柱４ａの上端と、昇り側の支柱４ｂの側面に取り付けてある。同様に、支柱４ｂと支柱４ｃにおいて、笠木５は降り側の支柱４ｂの上端と、昇り側の支柱４ｃの側面に取り付けてあり、支柱４ｃと支柱４ｄにおいて、笠木５は降り側の支柱４ｃの上端と、昇り側の支柱４ｄの側面に取り付けてある。そして、支柱４ｄと支柱４ｅにおいて、笠木５は両支柱４ｄ，４ｅの上端に取り付けてある。 The headboard 5 is a member extending in the horizontal direction attached to the upper end of the handrail. As described above, the struts are arranged in the order of the height of the upper end, and the height of the upper end of the adjacent struts is different, so that the cap 5 is attached to the upper end of the lower strut between the adjacent struts, The other end is attached to the side of the higher column. Here, one end side is the descending side of the stairs and the other end side is the ascending side of the stairs. That is, in the column 4a and the column 4b, the headboard 5 is attached to the upper end of the descending column 4a and the side surface of the ascending column 4b. Similarly, in the support 4b and the support 4c, the head 5 is attached to the upper end of the descending support 4b and the side of the ascending support 4c. In the support 4c and the support 4d, the head 5 is connected to the lower support 4c. It is attached to the upper end and the side surface of the ascending post 4d. And in the support | pillar 4d and the support | pillar 4e, the coping 5 is attached to the upper end of both the support | pillars 4d and 4e.

中桟１は、手摺の上下方向中間部に取り付けた水平方向に延びる部材である。隣接する支柱間において、笠木５の下側に、１本又は複数本の中桟１を取り付けてあり、より詳しくは、支柱４ａと支柱４ｂの間に１本、支柱４ｂと支柱４ｃの間及び支柱４ｃと支柱４ｄの間に２本、支柱４ｄと支柱４ｅの間に３本取り付けてある。そして、笠木５と中桟１の間隔及び中桟１同士の間隔は、隣接する支柱間の上端の高さの差（階段の１段の高さ）と同じである。よって、支柱を挟んで隣接する笠木５と中桟１又は中桟１同士が、同じ高さ位置となっている The intermediate rail 1 is a member that extends in the horizontal direction and is attached to an intermediate portion in the vertical direction of the handrail. Between adjacent struts, one or more middle rails 1 are attached to the lower side of the headboard 5, and more specifically, one between the struts 4a and 4b, between the struts 4b and 4c, and Two are attached between the pillar 4c and the pillar 4d, and three are attached between the pillar 4d and the pillar 4e. And the space | interval of the crosspiece 5 and the middle crosspiece 1 and the space | interval of the middle crosspieces 1 are the same as the difference of the height of the upper end between adjacent support | pillars (the height of one step of stairs). Therefore, the adjacent headboard 5 and the middle rail 1 or the middle rails 1 across the support are at the same height position.

次に、各部材同士の連結構造について詳述する。まず、図２に基づき、笠木５と支柱の連結構造について説明する。なお、図２は支柱４ａと支柱４ｂについて示したものであるが、他の支柱においても同じである。笠木５は、断面略矩形の形材であって、中空部５１を有し、下面の見込方向中央部には、長手方向に沿って延びる断面略コ字形の溝部５２を形成してあり、さらに溝部５２の底面には、長手方向に沿って延びる断面略Ｃ字形の係止部５３を形成してある。そして、笠木５の階段の降り側（支柱４ａ側）の端部には、端部部品６を取り付けてある。端部部品６は、略矩形平板形状のカバー部６１と、カバー部６１の笠木５側から突出する挿入片６２からなる。カバー部６１の笠木５側の面は掘り込んであって、笠木５の端部が丁度嵌まり込む形状となっており、カバー部６１に笠木５の端部が嵌まり込んだ状態で、端部部品６の挿入片６２が笠木５の中空部５１に挿入される。この挿入片６２に対して、笠木５の下面側（係止部５３の底面）からネジ止めして、笠木５に端部部品６を固定してある。そして、階段の降り側（支柱４ａ側）においては、支柱４ａの上端に、端面を覆う矩形平板状の上端板８をネジ止めして取り付けてあり、さらに上端板８の上面に、矩形平板状の連結板９をネジ止めして取り付けてある。連結板９は、笠木５の溝部５２に丁度納まる幅と厚さを有し、取り付けた支柱４ａから隣接する支柱４ｂ側に向けて突出している。この連結板９を溝部５２に納めるようにして、笠木５の階段の降り側の端部が支柱４ａに載置してあり、連結板９の突出部分の下側から、笠木５の係止部５３内に納めた裏板１０に対してネジ止めすることで、笠木５と階段の降り側の支柱４ａを連結してある。また、階段の昇り側（支柱４ｂ側）においては、支柱４ｂの側面に、突当具７を取り付けてある。突当具７は、端部部品６と略同じ形状で、カバー部７１と挿入片７２を有しており、カバー部７１を支柱４ｂにネジ止めしてある。そして、カバー部７１に笠木５の端部が嵌まり込んだ状態で、突当具７の挿入片７２が笠木５の中空部５１に挿入されており、この挿入片７２に対して、笠木５の下面側（係止部５３の底面）からネジ止めして、笠木５に突当具７を固定することで、笠木５と階段の昇り側の支柱４ｂを連結してある。なお、突当具７の高さ位置は、階段の降り側の支柱４ａの高さに合わせてあるので、笠木５は水平に設けられる。 Next, the connection structure between the members will be described in detail. First, based on FIG. 2, the connection structure of the headboard 5 and the support | pillar is demonstrated. Note that FIG. 2 shows the support column 4a and the support column 4b, but the same applies to other support columns. The headboard 5 is a shape member having a substantially rectangular cross section, has a hollow portion 51, and a groove portion 52 having a substantially U-shaped cross section extending along the longitudinal direction is formed in the center portion in the expected direction of the lower surface. A locking part 53 having a substantially C-shaped cross section extending along the longitudinal direction is formed on the bottom surface of the groove part 52. And the edge part 6 is attached to the edge part of the descending side (the support | pillar 4a side) of the staircase of the coping 5. The end part 6 includes a cover portion 61 having a substantially rectangular flat plate shape, and an insertion piece 62 protruding from the headboard 5 side of the cover portion 61. The surface of the cover portion 61 on the side of the headboard 5 is dug, and the end portion of the headboard 5 is just fitted into the cover portion 61. The insertion piece 62 of the part 6 is inserted into the hollow portion 51 of the headboard 5. The end piece 6 is fixed to the headboard 5 by screwing the insertion piece 62 from the lower surface side of the headboard 5 (the bottom surface of the locking portion 53). On the descending side of the stairs (the column 4a side), a rectangular flat plate-like upper end plate 8 that covers the end surface is screwed to the upper end of the column 4a, and a rectangular flat plate is formed on the upper surface of the upper end plate 8. The connecting plate 9 is attached with screws. The connecting plate 9 has a width and thickness that fits exactly in the groove 52 of the headboard 5 and protrudes from the attached support column 4a toward the adjacent support column 4b. The lower end of the staircase of the headboard 5 is placed on the column 4a so that the connecting plate 9 is accommodated in the groove portion 52, and the locking portion of the headboard 5 is provided below the protruding portion of the connecting plate 9. The headboard 5 and the column 4a on the descending side of the stairs are connected by screwing the back plate 10 housed in 53. Further, on the ascending side of the stairs (the column 4b side), the abutment tool 7 is attached to the side surface of the column 4b. The abutting tool 7 has substantially the same shape as the end part 6 and has a cover part 71 and an insertion piece 72, and the cover part 71 is screwed to the column 4b. The insertion piece 72 of the abutment tool 7 is inserted into the hollow portion 51 of the headboard 5 with the end of the headboard 5 fitted into the cover portion 71. By fixing with screws 7 from the lower surface side (the bottom surface of the locking portion 53) and fixing the abutting tool 7 to the headboard 5, the headboard 5 and the column 4b on the ascending side of the stairs are connected. In addition, since the height position of the abutment tool 7 is matched with the height of the column 4a on the descending side of the stairs, the headboard 5 is provided horizontally.

続いて、図３〜図５に基づき、中桟（横材）１と支柱（被取付材）の連結構造について説明する。なお、図３は支柱４ｂについて示したものであるが、他の支柱においても同じである。中桟１は、断面略矩形の形材であって、中空部１１を有し、下面の見込方向中央部には、長手方向に沿って延びる断面略コ字形の溝部１２を形成してある。そして、中桟１の端部には、小口部材２を取り付けてある。小口部材２は、１枚の金属平板を曲げて形成したものであり、中桟１の中空部１１に挿入してある裏板部２１と、中桟１の小口を覆うキャップ部２２を備える。キャップ部２２は、中桟１の断面よりわずかに大きな矩形平板状のものであって、下側から２本の切り込みを入れて見込方向中央部を中桟１側に折り曲げてあり、折り曲げた部分の下側は切欠部２３となっている。折り曲げた部分は、キャップ部２２から中桟１側へ水平向きに延びる延出面２４と、延出面２４の先端から下向きに延びる垂直面２５と、垂直面２５の下端から中桟１側へ水平向きに延びる裏板部２１を形成している。中桟１の中空部１１に挿入された裏板部２１は、中桟１の下面（溝部１２の底面）に上側から当接している。また、支柱４ｂの側面には、横材固定具３を取り付けてある。横材固定具３は、Ｌ字金具からなり、水平向きの載置部３１と、垂直向きの取付部３２を備え、見込幅は中桟１の溝部１２に丁度納まる幅である。取付部３２を支柱４ｂの側面にネジ止めして固定してあり、載置部３１が支柱４ｂから水平向きに突出している。そして、横材固定具３の載置部３１を溝部１２に納めるようにして、中桟１の端部を横材固定具３の載置部３１に載置してあり、載置部３１の下側から、溝部１２の底面を貫通して小口部材２の裏板部２１にネジ止めすることで、中桟１を支柱４ｂに固定するとともに、小口部材２を中桟１に固定してある。この際、横材固定具３の取付部３２は、小口部材２のキャップ部２２に形成した切欠部２３に納まっており、横材固定具３と小口部材２が干渉することはない。 Then, based on FIGS. 3-5, the connection structure of the middle crosspiece (horizontal member) 1 and a support | pillar (attached material) is demonstrated. FIG. 3 shows the support 4b, but the same applies to the other supports. The intermediate rail 1 is a shape member having a substantially rectangular cross section, and has a hollow portion 11, and a groove portion 12 having a substantially U-shaped cross section extending along the longitudinal direction is formed in the center portion in the expected direction of the lower surface. A small edge member 2 is attached to the end of the intermediate rail 1. The fore edge member 2 is formed by bending a single metal flat plate, and includes a back plate part 21 inserted into the hollow part 11 of the middle rail 1 and a cap part 22 covering the fore edge of the middle rail 1. The cap portion 22 is a rectangular flat plate that is slightly larger than the cross section of the middle rail 1, and has two cuts from the lower side and is bent at the center in the prospecting direction toward the middle rail 1 side. The lower side is a notch 23. The bent portion includes an extended surface 24 extending horizontally from the cap portion 22 toward the middle rail 1, a vertical surface 25 extending downward from the tip of the extended surface 24, and a horizontal direction from the lower end of the vertical surface 25 toward the middle rail 1 side. Is formed. The back plate portion 21 inserted into the hollow portion 11 of the middle rail 1 is in contact with the lower surface of the middle rail 1 (the bottom surface of the groove portion 12) from above. Further, a cross member fixture 3 is attached to the side surface of the support column 4b. The cross member fixture 3 is made of an L-shaped metal fitting, includes a horizontal mounting portion 31 and a vertical mounting portion 32, and the expected width is just a width that fits in the groove portion 12 of the middle rail 1. The attachment portion 32 is fixed to the side surface of the support column 4b with screws, and the placement portion 31 protrudes horizontally from the support column 4b. The end portion of the intermediate rail 1 is placed on the placement portion 31 of the crosspiece fixture 3 so that the placement portion 31 of the crosspiece fixture 3 is placed in the groove portion 12. From the lower side, by passing through the bottom surface of the groove portion 12 and screwed to the back plate portion 21 of the fore edge member 2, the middle beam 1 is fixed to the support column 4b, and the fore edge member 2 is fixed to the middle beam 1. . At this time, the mounting portion 32 of the cross member fixture 3 is housed in a notch 23 formed in the cap portion 22 of the fore edge member 2, so that the cross member fixture 3 and the fore edge member 2 do not interfere with each other.

次に、図６に基づき、このように構成した手摺の製造方法（施工手順）について説明する。まず、階段部に、支柱４ａ〜４ｅを上端の高さ順に並べて立設する（図６（ａ））。支柱４ａから支柱４ｄにかけては、上端の高さが階段の１段の高さ分ずつ高くなっており、支柱４ｄと支柱４ｅの上端の高さは同じである。次に、隣接する支柱間において、笠木５の一端を低い方の支柱の上端に取り付けるとともに、他端を高い方の支柱の側面に取り付ける（図６（ｂ））。ここでは、階段の降り側の支柱４ａ，４ｂ間から順に取り付けるものとし、まず、笠木５の階段の降り側（支柱４ａ側）の端部から係止部５３に裏板１０を挿入し、さらに端部に端部部品６を取り付け、下側からネジ止めして固定する。また、支柱４ａの上端の上端板８の上面に、連結板９をネジ止めして固定する。さらに、階段の昇り側の支柱４ｂの、階段の降り側の側面に、突当具７をネジ止めして固定する。この際、突当具７の高さ位置は、階段の降り側の支柱４ａの高さに合わせる。そして、階段の降り側において、連結板９を溝部５２に納めるようにして、笠木５の端部を支柱４ａに載置するとともに、階段の昇り側において、突当具７の挿入片７２を笠木５の中空部５１に挿入し、さらに連結板９の下側から笠木５の係止部５３内に納めた裏板１０に対してネジ止めするとともに、笠木５の下側から、中空部５１内に挿入した突当具７の挿入片７２にネジ止めする。次に、同様にして、他の支柱間に笠木５を取り付ける（図６（ｃ））。ただし、支柱４ｄと支柱４ｅの間においては、両端とも支柱４ｄ，４ｅの上端に取り付ける。次に、隣接する支柱間の笠木５の下側に中桟１を後付けする（図６（ｄ））。ここでは、階段の降り側の支柱４ａ，４ｂ間から順に取り付けるものとし、まず、両支柱４ａ，４ｂの対向する側面に、横材固定具３の取付部３２をネジ止めして固定する。この際、横材固定具３の高さ位置は、笠木５から階段の１段分の高さだけ離れた位置とする。次に、中桟１の両端に、それぞれ中空部１１に裏板部２１を挿入するようにして、小口部材２を取り付ける。そして、横材固定具３の載置部３１を溝部１２に納めるようにして、中桟１の両端部をそれぞれ横材固定具３の載置部３１に載置し、載置部３１の下側から、溝部１２の底面を貫通して小口部材２の裏板部２１にネジ止めする。次に、同様にして、他の支柱間にも中桟１を取り付け、手摺が完成する。 Next, based on FIG. 6, the manufacturing method (construction procedure) of the handrail comprised in this way is demonstrated. First, the columns 4a to 4e are erected on the staircase in order of the height of the upper end (FIG. 6 (a)). From the column 4a to the column 4d, the height of the upper end is increased by the height of one step of the staircase, and the height of the upper end of the column 4d and the column 4e is the same. Next, between the adjacent struts, one end of the headboard 5 is attached to the upper end of the lower strut, and the other end is attached to the side surface of the higher strut (FIG. 6B). Here, it is assumed that it is attached in order from between the columns 4a and 4b on the descending side of the stairs. First, the back plate 10 is inserted into the locking portion 53 from the end of the descending side (the column 4a side) of the staircase 5 and The end part 6 is attached to the end, and is fixed by screwing from below. Further, the connecting plate 9 is screwed and fixed to the upper surface of the upper end plate 8 at the upper end of the column 4a. Further, the abutting tool 7 is fixed to the side of the upright side of the stairs 4b on the descending side of the stairs by screwing. At this time, the height position of the abutment tool 7 is adjusted to the height of the column 4a on the descending side of the stairs. Then, on the descending side of the stairs, the end of the headboard 5 is placed on the column 4a so that the connecting plate 9 is placed in the groove 52, and the insertion piece 72 of the abutment tool 7 is placed on the headboard on the ascending side of the staircase. 5 and further screwed to the back plate 10 housed in the locking portion 53 of the headboard 5 from the lower side of the connecting plate 9, and from the lower side of the headboard 5 to the inside of the hollow portion 51. It is screwed to the insertion piece 72 of the abutment tool 7 inserted into. Next, in the same manner, the headboard 5 is attached between the other columns (FIG. 6C). However, between the columns 4d and 4e, both ends are attached to the upper ends of the columns 4d and 4e. Next, the intermediate rail 1 is retrofitted to the lower side of the headboard 5 between the adjacent columns (FIG. 6D). Here, it shall be attached in order from between the columns 4a and 4b on the descending side of the staircase, and first, the attachment portions 32 of the cross member fixture 3 are fixed to the opposite side surfaces of both columns 4a and 4b by screws. At this time, the height position of the cross member fixture 3 is set to a position separated from the headboard 5 by the height of one step of the stairs. Next, the edge member 2 is attached to both ends of the middle rail 1 so that the back plate portion 21 is inserted into the hollow portion 11 respectively. Then, the both ends of the middle rail 1 are placed on the placement portions 31 of the crosspiece fixture 3 so that the placement portions 31 of the crosspiece fixture 3 are accommodated in the grooves 12, respectively. From the side, it penetrates the bottom face of the groove part 12 and is screwed to the back plate part 21 of the fore edge member 2. Next, in the same manner, the middle rail 1 is attached between the other columns, and the handrail is completed.

このように構成した手摺によれば、階段の傾斜角度によらず、笠木５を水平に設けることができ、笠木５に手を掛けて階段を昇る際、垂直下向きにかかる体重を水平な笠木５で受けるので、安定して身体を支えることができる。 According to the handrail configured as described above, the headboard 5 can be provided horizontally regardless of the inclination angle of the staircase, and when the user climbs the staircase by placing a hand on the headboard 5, the weight of the vertical headboard 5 is lowered horizontally. So you can support your body stably.

また、この手摺の製造方法によれば、階段の傾斜角度によらず、笠木５を水平に設けることができ、笠木５に手を掛けて階段を昇る際、垂直下向きにかかる体重を水平な笠木５で受けるので、安定して身体を支えることができる手摺を製造できる。また、支柱４ａ〜４ｅと笠木５を組んでから、適宜支柱間に中桟１を後付けして、意匠を自在に変えることができる。 In addition, according to this method of manufacturing a handrail, the headboard 5 can be provided horizontally regardless of the inclination angle of the staircase, and when climbing the staircase by placing a hand on the headboard 5, Since it receives in 5, the handrail which can support a body stably can be manufactured. Moreover, after assembling the support posts 4a to 4e and the headboard 5, it is possible to change the design freely by retrofitting the intermediate rail 1 between the support posts as appropriate.

さらに、この手摺は、小口部材２のキャップ部２２が中桟１の小口を覆うので、小口が露出せず、意匠性が良好で、安全である。そして、中桟１を横材固定具３に固定するネジを、小口部材２を中桟１に固定するネジと兼用しているので、部品点数が少なく、施工が容易である。また、中桟１を支柱に連結する際、中桟１の端部を横材固定具３の載置部３１に載置した状態でネジ止め作業を行うことができるので、作業性がよい。 Furthermore, since the cap part 22 of the edge member 2 covers the edge of the middle rail 1 in this handrail, the edge is not exposed, the design is good, and it is safe. And since the screw which fixes the middle crosspiece 1 to the crosspiece fixture 3 is also used as the screw which fixes the edge member 2 to the middle crosspiece 1, the number of parts is small and construction is easy. In addition, when connecting the middle rail 1 to the support column, the screwing operation can be performed in a state where the end portion of the middle rail 1 is placed on the placement portion 31 of the cross member fixture 3, so that workability is good.

本発明は、上記の実施形態に限定されない。たとえば、上記のように階段の各段に支柱を１本ずつ設けるもののほか、１つの段に複数本の支柱を設けてもよいし、支柱を設けない段があってもよい。また、支柱は上端の高さ順に並べて立設するものであるが、同じ高さの支柱が並ぶ部分があってもよい。さらに、施工の際、階段の昇り側の支柱間から笠木を取り付けてもよい。また、中桟以外の水平向きの部材（横材）を、小口部材と横材固定具により被取付材に取り付けるものであってもよい。さらに、横材固定具は、下側以外の方向から横材に当接するものであってもよく、その場合も、横材固定具側から、小口部材の裏板部にネジ止めして固定する。 The present invention is not limited to the above embodiment. For example, in addition to providing one column for each step of the staircase as described above, a plurality of columns may be provided for one step, or there may be a step for which no column is provided. Moreover, although the support | pillar is arranged and arranged in order of the height of an upper end, there may be a part in which the support | pillar of the same height is located in a line. Furthermore, you may attach a headboard from between the support | pillars of the stairs rise side at the time of construction. Further, a horizontally oriented member (cross member) other than the middle rail may be attached to the attached material by the fore edge member and the cross member fixture. Further, the cross member fixing tool may be abutted against the cross member from a direction other than the lower side, and in that case, the cross member fixing tool is fixed to the back plate portion of the fore edge member from the side of the cross member fixing member. .
