    • A constricting member of a chair footrest ring is revealed. The constricting member is mainly a constricting sleeve with a hole mounted on a center thereof. A plurality of tapered-shaped mounting and fixing parts is disposed projectingly on an outer surface of the constricting sleeve, from top to bottom and expanded outward. At least one trench is also formed on the outer surface of the constricting sleeve. A positioning projective ring is projecting from and integrally formed on an outer edge on a top end of the constricting sleeve. The structure is simple so that the manufacturing cost is reduced and the assembling is more convenient and faster.
    • 揭示了椅垫脚环的收缩构件。 收缩构件主要是具有安装在其中心的孔的收缩套筒。 多个锥形安装和固定部分从顶部向底部突出地设置在收缩套的外表面上并向外扩展。 至少一个沟槽也形成在收缩套筒的外表面上。 定位投射环从收缩套筒顶端的外缘伸出并整体形成。 结构简单,制造成本降低,装配更方便快捷。

    • A constricting device for the footrest ring of a chair includes a constricting unit assembled between the center tube of a chair and the conical sleeve of a footrest ring. The constricting unit consists of a constricting main body and a fixing ring combining the constricting main body and the sleeve of the footrest ring. The constricting main body is a conical body fitted with the conical sleeve of the footrest ring, having its center bored with a fitting hole to be fitted around the center tube of the chair and its circumferential wall cut with plural openings. When the footrest ring is pressed downward by treading, the conical sleeve of the footrest ring will press the conical constricting main body and make it constricted to closely hold the center tube of the chair, able to stably fix the footrest ring on the center tube of the chair.
    • 用于椅子的脚踏环的收缩装置包括组合在椅子的中心管和脚踏环的锥形套筒之间的收缩单元。 收缩单元包括收缩主体和组合收缩本体和脚踏圈套筒的固定环。 收缩主体是装配有脚踏环的圆锥形套筒的圆锥体,其中心钻有一个装配孔,安装在椅子的中心管周围,其圆周壁切成多个开口。 脚蹬环通过踩踏向下按压时,脚踏环的锥形套筒将压缩锥形收缩主体并使其收缩,以紧紧地保持椅子的中心管,能够将脚踏板稳定地固定在中心管 椅子。
