It is composed of a pair of handrail positioning members 6, 6 provided.

そして、各手摺位置決め部材６は、ストップピン７と、ストップピン７を開口部５Ｃ方向に付勢するバネ８とを有し、手摺３ａ，３ｂは、筒体５に挿入された際に開口部５Ｃと対向する孔３ｃを有している。 Each handrail positioning member 6 has a stop pin 7 and a spring 8 that biases the stop pin 7 toward the opening 5C. It has a hole 3c facing 5C.

以下、各部について詳細に説明する。縦支柱１は、図１に示すように、支柱本体Ａと、支柱本体Ａの基端に設けられてＨ鋼ＷのフランジＦを挟持してＨ鋼Ｗに取付けられる挟持部材Ｂとからなり、また、支柱本体Ａの挟持部材Ｂに近接した外周位置に断面台形状の板バネからなる補強部材Ｃが取り付けられている。 Each part will be described in detail below. As shown in FIG. 1, the vertical strut 1 consists of a strut body A and a clamping member B provided at the base end of the strut body A and attached to the H steel W by clamping the flange F of the H steel W. Further, a reinforcing member C made of a plate spring having a trapezoidal cross section is attached to an outer peripheral position of the supporting column body A close to the holding member B. As shown in FIG.

詳細には、補強部材Ｃは、断面台形状であって両端部が支柱本体Ａの外面に溶着された本体部Ｃ１と、本体部Ｃ１の下端から延びて挟持部材Ｂに連結される支持片Ｃ２を有する。なお、本例では本体部Ｃ１は、断面台形状であるが断面Ｃ字状であってもよい。 More specifically, the reinforcing member C includes a main body portion C1 having a trapezoidal cross section and both ends of which are welded to the outer surface of the support main body A; have In this example, the main body portion C1 has a trapezoidal cross section, but may have a C-shaped cross section.

この補強部材Ｃは手摺装置Ｔを外側に倒す方向に荷重が作用して縦支柱１の基端側に回転方向のモーメントが発生しても、この縦支柱１の曲げや破損を防止させるものである。 This reinforcing member C prevents bending or breakage of the vertical support 1 even if a load is applied in the direction of tilting the handrail device T outward and a rotational moment is generated on the base end side of the vertical support 1. be.

また、挟持部材Ｂは、支柱本体Ａの基端に連結され互いに対向する一対の板部Ｂ４，Ｂ４を有する断面コ字状の挟持片Ｂ１と、支柱本体Ａ側の板部Ｂ４に貫通し軸方向移動自在に設けられたボルトＢ２と、ボルトＢ２の下端に設けられた皿Ｂ３とで構成されている。 The clamping member B includes a clamping piece B1 having a U-shaped cross section and a pair of plate portions B4, B4 connected to the base end of the column main body A and facing each other, and a shaft penetrating through the plate portion B4 on the column main body A side. It is composed of a bolt B2 provided movably in direction and a plate B3 provided at the lower end of the bolt B2.

そして、Ｈ鋼ＷのフランジＦに挟持片Ｂ１を差し込み、ボルトＢ２を締め付けると、ボルトＢ２が図中下方に移動して、図中下側の板部Ｂ４と皿Ｂ３とでフランジＦを挟持するため、縦支柱１をＨ鋼Ｗに起立させることができる。 Then, when the holding piece B1 is inserted into the flange F of the H steel W and the bolt B2 is tightened, the bolt B2 moves downward in the figure, and the flange F is held between the plate portion B4 and the plate B3 on the lower side in the figure. Therefore, the vertical strut 1 can be erected on the H steel W.

続いて、手摺取付け部材２は、図１に示すように、各縦支柱１の上端に設けられ手摺３ａ（３ｂ）を挿通可能な筒部２Ａと、この筒部２Ａに着脱自在に嵌合される楔Ｋとから構成され、筒部２Ａに手摺３ａ（３ｂ）を挿入した状態で楔Ｋを筒部２Ａと手摺３ａ（３ｂ）の間に圧入することで、手摺３ａ（３ｂ）が手摺取付け部材２によって保持される。 Next, as shown in FIG. 1, the handrail mounting member 2 is detachably fitted to a cylindrical portion 2A provided at the upper end of each vertical support 1 and through which the handrail 3a (3b) can be inserted. The handrail 3a (3b) is attached to the handrail by pressing the wedge K between the cylindrical portion 2A and the handrail 3a (3b) while the handrail 3a (3b) is inserted into the cylindrical portion 2A. It is held by member 2 .

また、手摺連結部材４は、前述したように、手摺３ａ（３ｂ）を挿入可能な筒体５と、筒体５に形成した一対の開口部５Ｃ，５Ｃと、各開口部５Ｃ，５Ｃに対してそれぞれ対向して設けた一対の手摺位置決め部材６，６とから構成されている。 Further, as described above, the handrail connecting member 4 includes a cylindrical body 5 into which the handrail 3a (3b) can be inserted, a pair of openings 5C, 5C formed in the cylindrical body 5, and openings 5C, 5C. and a pair of handrail positioning members 6, 6 provided facing each other.

詳細には、図４に示すように、筒体５の軸方向中央には、覗き孔５Ａが形成されており、覗き孔５Ａを挟んで図４中左右にそれぞれ開口部５Ｃ，５Ｃが形成されている。なお、図示するところでは、筒体５は、断面正方形に形成されているが、筒体５の断面形状は、手摺３ａ，３ｂの断面形状に一致するようにされているため、例えば手摺３ａ，３ｂの断面形状が円状の場合には、断面円筒状に形成される。 Specifically, as shown in FIG. 4, a peep hole 5A is formed in the center of the cylindrical body 5 in the axial direction, and openings 5C and 5C are formed on the left and right sides of FIG. ing. As shown in the figure, the cylindrical body 5 has a square cross section. When the cross-sectional shape of 3b is circular, it is formed to have a cylindrical cross-section.

次に、本発明の一実施の形態に係る手摺位置決め部材６を図２～図４に基づいて説明する。 Next, a handrail positioning member 6 according to one embodiment of the present invention will be described with reference to FIGS. 2 to 4. FIG.

図２～図４に示す手摺位置決め部材６は、筒体５の開口部５Ｃを覆うように設けられ底部１０ａと底部１０ａの両端部から起立する一対の側部１０ｂ，１０ｂを有する断面コ字状のケース１０と、底部１０ａに形成されたピン挿入孔１１に出没自在に挿入されたストップピン７と、ストップピン７を開口部５Ｃ側に向けて付勢するバネ８とを備える。 The handrail positioning member 6 shown in FIGS. 2 to 4 has a U-shaped cross section having a bottom portion 10a provided to cover the opening portion 5C of the cylindrical body 5 and a pair of side portions 10b, 10b rising from both ends of the bottom portion 10a. a case 10, a stop pin 7 which is retractably inserted into a pin insertion hole 11 formed in a bottom portion 10a, and a spring 8 which biases the stop pin 7 toward the opening portion 5C.

ストップピン７は、ピン挿入孔１１に挿通され開口部５Ｃに挿入可能なピン本体７Ａと、ピン本体７Ａから径方向に突出する一対の係止ピン９，９とを有し、一対の係止ピン９，９は、同一軸上に配置されている。 The stop pin 7 has a pin body 7A that can be inserted into the opening 5C through the pin insertion hole 11, and a pair of locking pins 9, 9 projecting radially from the pin body 7A. The pins 9, 9 are arranged on the same axis.

また、ストップピン７のケース１０の外方に突出する側の端部には、作業者が把持可能な把持部としてのリング１３が取り付けられている。 A ring 13 is attached to the end of the stop pin 7 protruding outward from the case 10 as a grip that can be gripped by the operator.

本実施の形態に係るバネ８は、圧縮コイルバネであって、ストップピン７の外周に配置されるとともに係止ピン９とケース１０の底部１０ａとの間に介装されて、ストップピン７を開口部５Ｃ側に向けて付勢している。 The spring 8 according to the present embodiment is a compression coil spring, which is arranged on the outer periphery of the stop pin 7 and interposed between the locking pin 9 and the bottom portion 10a of the case 10 to open the stop pin 7. It is biased toward the portion 5C side.

また、ケース１０の各側部１０ｂ，１０ｂには、互いに反対向きに切り欠かれて形成されて、ピン本体７Ａが開口部５Ｃに挿入されていない状態で各係止ピン９，９を引掛け可能な係止溝１２がそれぞれ設けられている。 In addition, the side portions 10b, 10b of the case 10 are formed by notching in opposite directions so that the locking pins 9, 9 are hooked when the pin body 7A is not inserted into the opening 5C. A possible locking groove 12 is provided in each case.

この手摺位置決め部材６によれば、ストップピン７のケース１０外に突出する端部には把持部としてのリング１３が取り付けられており、通常は図３中左側に示すように、リング１３を把持して、ストップピン７をバネ８に抗して外方に引き寄せながら回動することにより係止ピン９を係止溝１２に係合しておき、ストップピン７の軸方向の動きを止めておく。なお、把持部はリング１３でなくとも良く、作業者が把持できるようになっていれば形状や構成は特に限定されない。 According to this handrail positioning member 6, a ring 13 as a gripping portion is attached to the end of the stop pin 7 protruding outside the case 10, and the ring 13 is normally gripped as shown on the left side in FIG. Then, by rotating the stop pin 7 while pulling it outward against the spring 8 , the locking pin 9 is engaged with the locking groove 12, and the axial movement of the stop pin 7 is stopped. back. It should be noted that the grip portion does not have to be the ring 13, and the shape and configuration are not particularly limited as long as it can be gripped by the operator.

次に、この手摺位置決め部材６で手摺３ａ，３ｂの端部同士を対向させた状態で位置決めする場合は、予め筒体５の両側からそれぞれ手摺３ａ，３ｂの端部を差し込み、各手摺３ａ，３ｂの端部が筒体５の中央にあるかどうかを覗き孔５Ａから目視しておく。この際、各手摺３ａ，３ｂの端部が覗き孔５Ａの中央位置で向き合うと、各手摺３ａ，３ｂの端部に設けられた孔３ｃが筒体５の開口部５Ｃに対して対向するようになっているため、孔３ｃと開口部５Ｃの位置合わせが容易になる。 Next, when positioning the handrails 3a and 3b with the ends of the handrails 3a and 3b facing each other with the handrail positioning member 6, the ends of the handrails 3a and 3b are inserted from both sides of the cylindrical body 5 in advance, and the handrails 3a and 3b are positioned. Whether or not the end of 3b is in the center of cylinder 5 is visually observed through peep hole 5A. At this time, when the ends of the handrails 3a and 3b face each other at the central position of the peephole 5A, the holes 3c provided at the ends of the handrails 3a and 3b face the opening 5C of the cylindrical body 5. This facilitates alignment between the hole 3c and the opening 5C.

そして、各手摺３ａ，３ｂの先端同士が覗き孔５Ａの中央位置で対向していることを視認後、リング１３を把持しつつストップピン７を回転させて係止ピン９をケース１０の側部１０ｂの設けられていない開口側に向けるようにして係止ピン９の係止溝１２に対する係合を解除すると、係止ピン９とケース１０の底部１０ａの間に介装されたバネ８でストップピン７が押されて、このストップピン７の先端が筒体５の各開口部５Ｃと各手摺３ａ，３ｂの端部に設けられた孔３ｃに嵌合する。 Then, after confirming that the tips of the handrails 3a and 3b face each other at the central position of the peephole 5A, the stop pin 7 is rotated while holding the ring 13, and the locking pin 9 is moved to the side of the case 10. When the engagement of the locking pin 9 with the locking groove 12 is released so as to face the opening side where the 10b is not provided, the spring 8 interposed between the locking pin 9 and the bottom portion 10a of the case 10 stops. When the pin 7 is pushed, the tip of the stop pin 7 fits into each opening 5C of the cylindrical body 5 and the holes 3c provided at the ends of the handrails 3a and 3b.

その結果、各手摺３ａ，３ｂは、ストップピン７を介して、筒体５内に端部を対向させた状態で位置決めされ連結される。なお、本例では、各手摺３ａ，３ｂの端部を離間させた状態で、手摺３ａ，３ｂ同士を連結しているが、当接している状態で連結されてもよい。 As a result, the handrails 3a and 3b are positioned and connected via the stop pins 7 in the cylindrical body 5 with their ends facing each other. In this example, the handrails 3a and 3b are connected to each other with the ends of the handrails 3a and 3b separated from each other, but they may be connected while they are in contact with each other.

また、手摺位置決め部材６を複数設けることで、複数の手摺３ａ，３ｂを横方向に沿って連結でき、Ｈ鋼Ｗ等の被取付部材の長さに対応できる。 Further, by providing a plurality of handrail positioning members 6, a plurality of handrails 3a and 3b can be connected along the lateral direction, and the length of the attached member such as H steel W can be accommodated.

そして、手摺３ａ，３ｂを孔３ｃと開口部５Ｃから抜くときは、リング１３を指で引張り、ストップピン７を引き抜けば良い。 When removing the handrails 3a and 3b from the hole 3c and the opening 5C, the ring 13 is pulled by fingers and the stop pin 7 is pulled out.
