また、前記回動片４２、４３の前記嵌合部４２ｂ、４３ｂは、下方部が先細状とした円管状であり、嵌合部４２ｂ、４３ｂには内方に窪む凹状部４２ｉ、４３ｉを縦方向に形成している。
前記凹状部４２ｉ、４３ｉは、円管状部材４１、４１との嵌合を強固にする必要があるときに、棒状の楔を組み込むことができるようにしている。 Further, the fitting portions 42b and 43b of the rotating pieces 42 and 43 are circular pipes whose lower portions are tapered, and the fitting portions 42b and 43b are provided with concave portions 42i and 43i that are recessed inwardly. It is formed in the vertical direction.
The concave portions 42i and 43i can incorporate rod-shaped wedges when it is necessary to strengthen the fitting with the tubular members 41 and 41.

このように構成した２つの回動片４２、４３は、圧縮コイルばね６及び回動軸７を使用して脚カバー４ａ、４ａを固定した円管状部材４１、４１に組込むことにより、支持脚４とするのである。
回動軸７は、平頭付の軸により構成し、回動軸７の回動片４２、４３への固定は、端部に形成した環状溝にＥ形止め輪７ａを嵌め込むことにより行うのである。 The two rotating pieces 42 and 43 configured as described above are incorporated into the circular tubular members 41 and 41 to which the leg covers 4a and 4a are fixed using the compression coil spring 6 and the rotating shaft 7, so that the supporting leg 4 It is.
The rotation shaft 7 is constituted by a shaft with a flat head, and the rotation shaft 7 is fixed to the rotation pieces 42 and 43 by fitting an E-shaped retaining ring 7a into an annular groove formed at the end. is there.

圧縮コイルばね６は、材質を硬鋼線Ｃ種（ＳＷ−Ｃ）とし、直径２ｍｍ、コイル平均径１０．５ｍｍ、コイル内径８．５ｍｍ、有効巻数８、総巻数１０でとし、自由長を支持脚４、４がバリケード使用時のハの字状（開脚状態）となるときに若干の圧縮状態となる寸法（例えば、６０ｍｍ）、端部をクローズドエンドしている。
そして、連結部材３３、３３に取付軸５を介して支持脚４、４を取付けて、支持脚４、４をバリケード使用時のハの字状とした図１（ａ）に示す開脚状態では、２つの回動片４２、４２の角度α（図５参照）は、支持脚４を連結部材３３に取付前の２つの回動片４２、４２の角度βよりも２〜３度狭くなる位置で、支持脚４がバリケード使用時の使用時係止膨出部３５ａ及び使用時係止孔部３５ｂに係合するようにしている。 The compression coil spring 6 is made of hard steel wire class C (SW-C), has a diameter of 2 mm, a coil average diameter of 10.5 mm, a coil inner diameter of 8.5 mm, an effective number of turns of 8, and a total number of turns of 10 and supports a free length. The legs 4 and 4 have dimensions (for example, 60 mm) that are slightly compressed when the barricade is used when the barricade is used (open leg state), and the ends are closed end.
In the open leg state shown in FIG. 1 (a), the support legs 4 and 4 are attached to the connecting members 33 and 33 via the attachment shaft 5, and the support legs 4 and 4 are shaped like a C when using a barricade. The angle α (see FIG. 5) of the two rotating pieces 42, 42 is a position that is 2 to 3 degrees narrower than the angle β of the two rotating pieces 42, 42 before the support leg 4 is attached to the connecting member 33. Thus, the support leg 4 is adapted to engage with the locking bulge 35a and the locking hole 35b when in use when the barricade is used.

このような角度α、β（例えばαを４０度、βを４２．５度）関係とすることにより、バリケード１を使用するときに、支持脚４がバリケード使用時の使用時係止膨出部３５ａ及び使用時係止孔部３５ｂに係合した際に、圧縮コイルばね６が自然長よりも圧縮されて弾性力が２つの回動片４２、４３を離反する方向に付勢するようにしている。
以上のように形成したバリケード１における支持脚４を使用時係止部３５（使用時係止膨出部３５ａ及び使用時係止孔部３５ｂ）から不使用時係止部３６（不使用時係止切欠部３６ａ及び不使用時係止孔部３６ｂ）に又はその逆に係止するように切替える際は、支持脚４、４のそれぞれ２本の円管状部材４１、４１を圧縮コイルばね６の付勢力に抗して近づける方向に操作することにより、支持脚４をバリケード使用時のハの字状とバリケード不使用時の平行状とに簡単に切替えることができながら、圧縮コイルばね６の弾性力により支持脚４、４を各係止部３５、３６に確実に保持することができるのである。 By using such a relationship between angles α and β (for example, α is 40 degrees and β is 42.5 degrees), when the barricade 1 is used, the support leg 4 is used when the barricade is used. When the compression coil spring 6 is compressed from its natural length and the elastic force biases the two rotating pieces 42 and 43 away from each other when engaged with the locking hole 35b and the locking hole 35b when in use. Yes.
When the support leg 4 of the barricade 1 formed as described above is used, the locking portion 35 (the locking bulge portion 35a and the locking hole 35b when used) is not used and the locking portion 36 is not used (when not used). When switching so as to be locked to the notch 36a and the locking hole 36b when not in use or vice versa, the two tubular members 41, 41 of the support legs 4, 4 are respectively connected to the compression coil spring 6. By operating the support leg 4 in a direction to approach the urging force, the elasticity of the compression coil spring 6 can be easily switched between a square shape when the barricade is used and a parallel shape when the barricade is not used. The support legs 4, 4 can be reliably held by the locking portions 35, 36 by force.
