Abstract
【解決手段】支柱1は、中空管体2と、中空管体2に挿入される挿入体3と、挿入体3と中空管体2とを解除自在に固定する固定用ボルト4とを備える。中空管体2には、内部を自由落下よりも遅い速度で落下可能に摺動する摺動部材5が配置され、摺動部材5には、摺動部材5と挿入体3とが接触する個所に位置させて傾斜面52cが形成され、挿入体3には、挿入体3と摺動部材5との相対的な位置が所定間隔以上開かないように、摺動部材5の張出部51aを受ける受け部32aが設けられる。

Description
Claims (1)
- 上下方向に延びて上端が開口した中空の中空管体と、該中空管体に上端の開口から挿入される挿入体と、該挿入体と前記中空管体とを解除自在に固定する固定機構とを備え、該固定機構の固定を解除して、前記挿入体を前記中空管体に挿入することにより縮み、前記挿入体を前記中空管体から突出させることにより伸びる伸縮自在な支柱の伸縮構造において、
前記中空管体には、内部を自由落下よりも遅い速度で落下可能に摺動する摺動部材が配置され、
該摺動部材又は前記挿入体には、前記摺動部材と前記挿入体とが接触する個所に位置させて、前記摺動部材と前記挿入体とが接触したときに挿入体の自由落下に伴う鉛直方向の力の一部を水平方向の力に変換させる傾斜面が形成され、
前記挿入体には、当該挿入体と前記摺動部材との相対的な位置が所定間隔以上開かないように、前記摺動部材を受ける受け部が設けられることを特徴とする支柱の伸縮構造。
