Description

この発明は、金属製の芯材に被覆材を被せた手摺部材に接続するエルボ部材に関する。   The present invention relates to an elbow member connected to a handrail member in which a metal core is covered with a covering material.

近年、各種施設において、バリアフリー化推進のため、連続手摺の設置が要望される場合が多くなっており、このような連続手摺の基本的な手摺部材として、強度に優れた金属製の芯材の外周に手触り感のよい被覆材を被せたものが使用されることがある。   In recent years, installation of continuous handrails has been demanded in various facilities for the purpose of barrier-free promotion. As a basic handrail member of such continuous handrails, a metal core material having excellent strength In some cases, the outer periphery of the cover is covered with a coating material with a good touch feeling.

ところが、階段における壁面のコーナー部等、屈曲させつつ勾配を変化させる必要がある部分においては、従来のエルボ部材では、屈曲部の両側で勾配を変化させることができず、対応することができない。   However, in a portion where the gradient needs to be changed while being bent, such as a corner portion of a wall surface in a staircase, the conventional elbow member cannot change the gradient on both sides of the bent portion and cannot cope with it.

このため、手摺を途切れさせることなく連続手摺とする強い要望がある場合には、コーナー部に用いる手摺部材の芯材の一側に多数のスリットを刻設し、手摺部材を撓めるように曲げて対応しているのが現状である（下記特許文献１参照）。   For this reason, when there is a strong demand for a continuous handrail without interrupting the handrail, a large number of slits are engraved on one side of the core material of the handrail member used for the corner portion, and the handrail member is bent. The current situation is to bend (see Patent Document 1 below).

特開２００２−２１２８１号公報Japanese Patent Laid-Open No. 2002-21281

しかしながら、上記のように芯材に多数のスリットを刻設した手摺部材は、製作に多大な手間を要するほか、施工現場で撓めるように曲げる際、大きな力を要し、また、スリットの幅等の制約により、所望の角度に曲げられない場合もある。   However, the handrail member in which a large number of slits are engraved in the core as described above requires a great deal of labor for production, and requires a large force when bent so as to bend at the construction site. In some cases, it cannot be bent to a desired angle due to restrictions such as width.

そこで、この発明は、金属製の芯材に被覆材を被せた手摺部材を用いて、階段における壁面のコーナー部等に簡単に連続手摺を設置できるようにすることを課題とする。   Accordingly, an object of the present invention is to enable a continuous handrail to be easily installed at a corner portion of a wall surface of a staircase using a handrail member in which a metal core is covered with a covering material.

上記課題を解決するため、この発明は、金属製の芯材に被覆材を被せた手摺部材に接続する手摺用エルボ部材において、手摺の曲がった部分を構成する本体と、これに内装される回転体とを備え、前記本体は、軸線が曲がった屈曲部に、端面で開口して手摺部材が嵌め入れられる嵌入部を連設したものとし、前記回転体は、本体の嵌入部の奥側に内挿されるフランジ部の中心部から係入軸部が嵌入部の外側へ向かって軸方向に延びる形状とし、前記本体と回転体とを嵌入部の軸線を中心に相対回転可能で軸方向に移動しないようにフランジ部で結合し、手摺部材の嵌入部への嵌め入れに伴い、係入軸部が手摺部材の芯材に挿入されて、周方向に係止されるようにしたのである。   In order to solve the above-described problems, the present invention provides a handrail elbow member connected to a handrail member having a metal core covered with a covering material, a main body constituting a bent portion of the handrail, and a rotation incorporated in the main body. And the main body is provided with a fitting portion that is opened at an end surface and into which a handrail member is fitted in a bent portion having a bent axis, and the rotating body is provided at the back of the fitting portion of the main body. The engaging shaft portion extends in the axial direction from the center portion of the flange portion to be inserted toward the outside of the insertion portion, and the main body and the rotating body can be relatively rotated around the axis of the insertion portion and moved in the axial direction. In order to prevent this, the flange portion is coupled, and with the fitting of the handrail member into the fitting portion, the engaging shaft portion is inserted into the core member of the handrail member and locked in the circumferential direction.

また、前記回転体のフランジ部には、嵌入部の軸線を中心とする弧状長穴を形成し、嵌入部の開口側から弧状長穴を介して案内ピンを本体にねじ込み、案内ピンが緩んだ状態では、弧状長穴の中心角の範囲で本体と回転体との相対回転が許容され、案内ピンを締め付けると、本体と回転体とが所定の角度で固定されるようにしたのである。   In addition, an arc-shaped elongated hole centering on the axis of the fitting portion is formed in the flange portion of the rotating body, and the guide pin is screwed into the main body from the opening side of the fitting portion via the arc-shaped elongated hole, so that the guide pin is loosened. In the state, relative rotation between the main body and the rotating body is allowed in the range of the central angle of the arc-shaped elongated hole, and when the guide pin is tightened, the main body and the rotating body are fixed at a predetermined angle.

また、これに代えて、前記回転体のフランジ部を軸方向及び径方向に保持する保持リングを備え、回転体のフランジ部を、嵌入部の奥側へ向く保持リングの内周側の環状凹所に嵌合させ、本体と回転体とを相対回転可能としたのである。   Instead of this, a holding ring for holding the flange portion of the rotating body in the axial direction and the radial direction is provided, and the flange portion of the rotating body is annular concave on the inner peripheral side of the holding ring facing the back side of the fitting portion. The main body and the rotating body can be rotated relative to each other.

さらに、前記保持リングの環状凹所より外周側に位置する貫通穴を介して嵌入部の開口側から案内ピンを本体にねじ込み、案内ピンが緩んだ状態では、本体と回転体との全周に及ぶ相対回転が許容され、案内ピンを締め付けると、本体と回転体とが所定の角度で固定されるようにしたのである。   Furthermore, the guide pin is screwed into the main body from the opening side of the fitting portion through the through hole located on the outer peripheral side from the annular recess of the holding ring, and when the guide pin is loosened, the entire periphery of the main body and the rotating body is provided. When the guide pin is tightened, the main body and the rotating body are fixed at a predetermined angle.

この発明に係るエルボ部材を使用して連続手摺を施工する際、手摺部材を本体の一方の嵌入部に嵌め入れて、回転体の係入軸部に係止すると、一方の嵌入部の軸線を中心に本体を回転させることができるので、他方の嵌入部にも手摺部材を嵌め入れて、階段における壁面のコーナー部等に簡単に連続手摺を設置することができる。   When constructing a continuous handrail using the elbow member according to the present invention, when the handrail member is fitted into one insertion portion of the main body and locked to the engagement shaft portion of the rotating body, the axis of the one insertion portion is Since the main body can be rotated in the center, a handrail member can be fitted into the other insertion portion, and a continuous handrail can be easily installed at the corner portion of the wall surface of the stairs.

まず、この発明の第１実施形態を図１〜図４に基づいて説明する。   First, a first embodiment of the present invention will be described with reference to FIGS.

このエルボ部材は、図１及び図２に示すように、円形断面の手摺部材３０に接続されるものであり、手摺の曲がった部分を構成する本体１と、これに内装される回転体２とを備えている。これらは、あまり荷重が作用するものでないことから、通常プラスチック製とされるが、手摺部材３０の質感等に応じて金属製としてもよい。   As shown in FIGS. 1 and 2, this elbow member is connected to a handrail member 30 having a circular cross section, and includes a main body 1 that forms a bent portion of the handrail, and a rotating body 2 that is housed therein. It has. These are usually made of plastic because they do not act so much, but they may be made of metal depending on the texture of the handrail member 30 and the like.

本体１は、軸線が９０°湾曲した屈曲部３の両側に、端面で開口して手摺部材３０が嵌め入れられる短い円管状の嵌入部４が連設された構成とされている。回転体２は、本体１の嵌入部４の奥側に内挿される円板状のフランジ部５と、その中心部から嵌入部４の外側へ向かって軸方向に延びる四角柱状の係入軸部６とを一体化した形状とされている。   The main body 1 has a configuration in which short tubular insertion portions 4 that are opened at end surfaces and into which the handrail member 30 is inserted are continuously provided on both sides of the bent portion 3 whose axis is curved by 90 °. The rotating body 2 includes a disc-shaped flange portion 5 inserted in the back side of the insertion portion 4 of the main body 1, and a quadrangular columnar engagement shaft portion extending in the axial direction from the center portion toward the outside of the insertion portion 4. 6 and the integrated shape.

本体１において、嵌入部４の奥底部には、屈曲部３の内側付近となる部分を除き、中心部から径方向に離れて、ねじ穴７が周方向に４５°間隔で７個設けられ、中心部に軸穴８が設けられている。   In the main body 1, seven screw holes 7 are provided at 45 ° intervals in the circumferential direction, apart from the center portion in the radial direction, except for the portion near the inside of the bent portion 3, at the bottom of the fitting portion 4. A shaft hole 8 is provided at the center.

また、回転体２において、フランジ部５には、本体１の嵌入部４の軸線を中心として湾曲した弧状長穴９が形成され、弧状長穴９は、中心角が９０°とされて、対称位置に２個配置されている。嵌入部４の奥底側へ向くフランジ部５の中心部には、軸方向に延びる丸棒状の回転軸部１０が突設されている。   Further, in the rotating body 2, the flange portion 5 is formed with an arc-shaped elongated hole 9 that is curved around the axis of the fitting portion 4 of the main body 1, and the arc-shaped elongated hole 9 has a central angle of 90 ° and is symmetric. Two are arranged at the position. A round bar-shaped rotating shaft 10 extending in the axial direction protrudes from the center of the flange portion 5 facing the bottom side of the fitting portion 4.

係入軸部６の一方の対向する側面には、軸方向に延びる係合溝１１が形成され、係入軸部６の先端部には、他方の対向する側面にわたって貫通する貫通穴１２が軸線に直交する方向へ延びるように形成されている。   An engaging groove 11 extending in the axial direction is formed on one opposing side surface of the engaging shaft portion 6, and a through hole 12 penetrating over the other opposing side surface is formed at the tip of the engaging shaft portion 6. It is formed to extend in a direction orthogonal to the direction.

このエルボ部材の組み立てに際しては、図２及び図３に示すように、本体１の嵌入部４の奥側に回転体２のフランジ部５を内挿して、回転軸部１０を軸穴８に挿し込み、小ねじである案内ピン２１を、嵌入部４の開口側から弧状長穴９を介して対称位置にあるいずれか２個のねじ穴７にねじ込んで、本体１と回転体２とをフランジ部５で結合する。この状態では、係入軸部６の先端部が嵌入部４から突出し、貫通穴１２が露出している。   When assembling the elbow member, as shown in FIGS. 2 and 3, the flange portion 5 of the rotating body 2 is inserted into the back side of the fitting portion 4 of the main body 1, and the rotating shaft portion 10 is inserted into the shaft hole 8. The guide pin 21 which is a small screw is screwed into any two screw holes 7 at symmetrical positions from the opening side of the fitting portion 4 through the arc-shaped elongated holes 9, and the main body 1 and the rotating body 2 are flanged. Combine at part 5. In this state, the tip end portion of the engagement shaft portion 6 protrudes from the insertion portion 4 and the through hole 12 is exposed.

このように組み立てると、本体１と回転体２とは、嵌入部４の軸線を中心に相対回転可能となり、軸方向には移動せず、案内ピン２１が緩んだ状態では、図４（ａ）及び（ｂ）に示すように、弧状長穴９の中心角の範囲で本体１と回転体２との相対回転が許容され、案内ピン２１を締め付けると、本体１と回転体２とが所定の角度で固定される。   When assembled in this manner, the main body 1 and the rotating body 2 can be rotated relative to each other about the axis of the insertion portion 4, do not move in the axial direction, and in a state where the guide pin 21 is loose, FIG. And as shown to (b), relative rotation with the main body 1 and the rotary body 2 is accept | permitted in the range of the center angle of the arc-shaped long hole 9, and if the guide pin 21 is tightened, the main body 1 and the rotary body 2 will be predetermined | prescribed. Fixed at an angle.

なお、初期状態では、一方の弧状長穴９を介して、その一端側に案内ピン２１を位置させ、他端側に対応するねじ穴７に固定ピン２３をねじ込んでおき、施工時に固定ピン２３を抜き取ると、本体１に対し回転体２が一方向へのみ回転可能となり、本体１の両側の嵌入部４において、回転体２の回転可能な方向が逆になるようにしておく。   In the initial state, the guide pin 21 is positioned on one end side of the arc-shaped elongated hole 9 and the fixing pin 23 is screwed into the screw hole 7 corresponding to the other end side. Is removed, the rotating body 2 can rotate in only one direction relative to the main body 1, and the rotating direction of the rotating body 2 is reversed in the fitting portions 4 on both sides of the main body 1.

これにより、階段部分の連続手摺の施工に際し、下階側と上階側のエルボ部材を、基準となる手摺部材に対し回転体２の回転方向が逆向きとなるように配置すると、容易に施工することができる。なお、勾配の変化がない部分に設置する場合には、両側の嵌入部４の固定ピン２３をそのままにしておくと、通常のエルボ部材と同様に使用できる。   As a result, in the construction of the continuous handrail of the staircase, if the elbow members on the lower floor side and the upper floor side are arranged so that the rotation direction of the rotating body 2 is opposite to the reference handrail member, the construction is easily performed. can do. In addition, when installing in the part which does not change a gradient, if the fixing pin 23 of the insertion part 4 of both sides is left as it is, it can be used similarly to a normal elbow member.

一方、このエルボ部材が接続される手摺部材３０は、図１に示すように、アルミニウム等の金属から成るコ字状断面の芯材３１の外周に、手触り感のよい合成樹脂製や木製の被覆材３２を被せたものとされている。   On the other hand, as shown in FIG. 1, the handrail member 30 to which the elbow member is connected is made of a synthetic resin or wooden covering that is easy to touch on the outer periphery of a core 31 having a U-shaped cross section made of metal such as aluminum. The material 32 is covered.

芯材３１の対をなす側壁の内面には、軸方向に延びる係合突条３３が形成され、他の一方の側壁には、開放溝が形成されている。また、これに対応して、被覆材３２にも開放溝が形成され、これらの開放溝には、施工時にゴム等から成る溝埋材３４が嵌められて、手摺部材３０の外周面が切れ目のない円筒面とされる。   Engagement ridges 33 extending in the axial direction are formed on the inner surfaces of the side walls forming a pair of core members 31, and an open groove is formed on the other side wall. Correspondingly, open grooves are also formed in the covering material 32, and a groove filling material 34 made of rubber or the like is fitted into these open grooves, and the outer peripheral surface of the handrail member 30 is cut. There is no cylindrical surface.

このような手摺部材３０による手摺の施工に際し、上記のようなエルボ部材を使用する場合には、図２及び図３に示すように、接続される手摺部材３０のうち、一方の手摺部材３０を本体１の一方の嵌入部４に嵌め入れ、これに伴い、係入軸部６の係合溝１１に芯材３１の係合突条３３を係合させて、係入軸部６を芯材３１に挿入する。   In the case of using the elbow member as described above in the construction of the handrail by such a handrail member 30, as shown in FIGS. 2 and 3, one handrail member 30 is connected among the handrail members 30 to be connected. The main shaft 1 is fitted into one of the insertion portions 4, and the engagement protrusions 33 of the core material 31 are engaged with the engagement grooves 11 of the engagement shaft portion 6. Insert into 31.

次に、手摺部材３０の溝埋材３４を芯材３１の開放溝に嵌める前の状態で、芯材３１の開放溝から貫通穴１２を介して、タッピンねじ２２を芯材３１の開放溝と対向する閉塞側の側壁にねじ込むと、一方の手摺部材３０と回転体２とが固定される。   Next, in a state before the groove filling material 34 of the handrail member 30 is fitted into the open groove of the core material 31, the tapping screw 22 is connected to the open groove of the core material 31 through the through hole 12 from the open groove of the core material 31. When screwed into the opposite side wall, the one handrail member 30 and the rotating body 2 are fixed.

この際、一方の嵌入部４において、上述のように、固定ピン２３を抜き取り、案内ピン２１を緩めると、手摺部材３０に対して、嵌入部４の軸線を中心に本体１を９０°の範囲で回転させることができるので、他方の嵌入部４にも手摺部材３０を嵌め入れて、所望の方向に向けることができる。   At this time, when the fixing pin 23 is pulled out and the guide pin 21 is loosened in one of the insertion portions 4 as described above, the main body 1 is in a range of 90 ° with respect to the handrail member 30 around the axis of the insertion portion 4. Therefore, the handrail member 30 can be fitted into the other fitting portion 4 and directed in a desired direction.

例えば、図９に示すような階段部分の連続手摺の施工に際しては、一方の手摺部材３０をブラケット３５で壁面のコーナー部を挟んだ一側に固定した状態で、この手摺部材３０にエルボ部材の一方の嵌入部４を接続する。このとき、他方の嵌入部４が所定の方向へ向くように本体１を回転させ、案内ピン２１及び固定ピン２３を締め付けてその角度に本体１を固定する。   For example, in the construction of the continuous handrail of the staircase portion as shown in FIG. 9, one handrail member 30 is fixed to one side with the bracket 35 sandwiching the corner portion of the wall surface. One insertion part 4 is connected. At this time, the main body 1 is rotated so that the other insertion portion 4 faces in a predetermined direction, and the guide pin 21 and the fixing pin 23 are tightened to fix the main body 1 at the angle.

その後、他方の手摺部材３０をエルボ部材の他方の嵌入部４に嵌め入れ、この手摺部材３０をブラケット３５で壁面のコーナー部を挟んだ他側に固定し、それぞれの手摺部材３０の芯材３１及び被覆材３２の開放溝に、外周を円滑化して手当たり感をよくするため、溝埋材３４を嵌め込む。   Thereafter, the other handrail member 30 is fitted into the other insertion portion 4 of the elbow member, and the handrail member 30 is fixed to the other side of the corner portion of the wall surface by the bracket 35, and the core material 31 of each handrail member 30. In addition, a groove filling material 34 is fitted into the open groove of the covering material 32 in order to smooth the outer periphery and improve the feeling of handling.

そして、連続手摺の両端には、終端となるエルボ部材を取り付ける。このエルボ部材としては、一方の嵌入部４にのみ回転体２を内装したものを用いるとよい。この場合、他方の嵌入部４を壁面の方向だけでなく、下方へも向けることができる。なお、終端となるエルボ部材の他方の嵌入部４には、開口部を塞ぐキャップ１３を嵌めておくとよい。   And the elbow member used as the termination | terminus is attached to the both ends of a continuous handrail. As this elbow member, it is preferable to use a member in which the rotating body 2 is housed only in one fitting portion 4. In this case, the other insertion portion 4 can be directed not only in the direction of the wall surface but also downward. In addition, it is good to fit the cap 13 which closes an opening part in the other insertion part 4 of the elbow member used as the termination | terminus.

次に、この発明の第２実施形態を図５〜図８に基づいて説明する。なお、ここでは、主として上記第１実施形態との相違点について述べ、第１実施形態と共通の機能を有する部分には、同一の符号を付して、その説明を省略する。   Next, a second embodiment of the present invention will be described with reference to FIGS. Note that here, mainly the differences from the first embodiment will be described, and parts having the same functions as those of the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

このエルボ部材は、本体１及び回転体２に加えて、嵌入部４に嵌め入れられる保持リング１５を備えている。保持リング１５には、嵌入部４の奥側へ向く内周側に環状凹所１６が形成されると共に、環状凹所１６より外周側に２個の貫通穴１７が対向位置に形成されている。貫通穴１７は、ねじ穴とされているが、ねじの形成は省略してもよい。   In addition to the main body 1 and the rotating body 2, the elbow member includes a holding ring 15 that is fitted into the fitting portion 4. The holding ring 15 is formed with an annular recess 16 on the inner peripheral side facing the inner side of the fitting portion 4, and two through holes 17 are formed on the outer peripheral side of the annular recess 16 at opposing positions. . The through hole 17 is a screw hole, but the formation of a screw may be omitted.

回転体２のフランジ部５は、嵌入部４の内径よりも小径とされて、保持リング１５の環状凹所１６に回動自在に嵌め合わされ、係入軸部６は、保持リング１５の中央部の穴に挿通されている。保持リング１５は、案内ピン２１を貫通穴１７を介して嵌入部４の奥底部のねじ穴１４にねじ込むことにより、本体１に固定されている。   The flange portion 5 of the rotating body 2 has a smaller diameter than the inner diameter of the fitting portion 4 and is fitted to the annular recess 16 of the holding ring 15 so as to be freely rotatable. The engaging shaft portion 6 is a central portion of the holding ring 15. Is inserted through the hole. The retaining ring 15 is fixed to the main body 1 by screwing the guide pin 21 into the screw hole 14 at the bottom of the fitting portion 4 through the through hole 17.

このようなエルボ部材において、環状凹所１６の深さよりも保持リング１５の厚さを僅かに大きく設定しておくと、案内ピン２１を緩めた状態で、本体１と回転体２とを、嵌入部４の軸線を中心として３６０°自由に相対回転させて、所定の角度に調整することができ、案内ピン２１を締め付けると、本体１と回転体２とを所定の角度で固定することができるものとなる。   In such an elbow member, if the thickness of the holding ring 15 is set slightly larger than the depth of the annular recess 16, the main body 1 and the rotating body 2 are fitted in a state where the guide pin 21 is loosened. The main body 1 and the rotating body 2 can be fixed at a predetermined angle by tightening the guide pin 21 by relatively rotating 360 degrees freely about the axis of the portion 4 and adjusting the predetermined angle. It will be a thing.

一方、環状凹所１６の深さよりも保持リング１５の厚さを小さく設定した場合には、案内ピン２１の締め付けの程度にかかわらず、本体１と回転体２とを、嵌入部４の軸線を中心として３６０°自由に相対回転させることができる。   On the other hand, when the thickness of the holding ring 15 is set smaller than the depth of the annular recess 16, the main body 1 and the rotating body 2 are connected to the axis of the insertion portion 4 regardless of the degree of tightening of the guide pin 21. The relative rotation can be freely performed 360 ° as the center.
