CHUCK FOR PULLING OUT LONGITUDINAL MEMBER
To provide a technique which enables noninvasive gripping of an existing longitudinal member and easy pulling-out of it from an installation place at low noise and low vibrations.SOLUTION: A chuck 20 detachably fitted to a longitudinal member 12 comprises: an outer frame 50 configured to have a plurality of divided bodies 52 arranged in a peripheral direction of the longitudinal member 12; and a cylindrical contact layer 40 supported on an inner surface of the outer frame 50 and having elasticity in at least a radial direction and having a soft material in at least a surface layer. The contact layer 40 includes an array of a plurality of discrete bodies 44 disposed so as to be arranged in a discrete manner in the peripheral direction of the longitudinal member 12. The outer frame 50 includes, on its inner surface, a plurality of recesses 58 each capable of partially storing a plurality of discrete bodies 44 behind them, as an array arranged in a discrete manner in the peripheral direction of the longitudinal member 12.SELECTED DRAWING: Figure 1
【課題】既設の長手部材を非侵襲的に把持してその設置場所から低騒音・低振動でかつ簡易に引き抜くことを可能にする技術を提供する。【解決手段】長手部材１２に着脱可能に装着されるチャック２０が開示されている。そのチャック２０は、長手部材１２の周方向に並ぶ複数の分割体５２を有するように構成される外枠５０と、その外枠５０の内面に支持され、少なくとも半径方向において弾性を有するとともに少なくとも表層において軟質材を有する筒状の接触層４０とを含む。その接触層４０は、長手部材１２の周方向に離散的に並ぶように配置される複数の離散体４４の配列を含む。外枠５０は、自身の内面において、複数の離散体４４をそれらの背後においてそれぞれ部分的に収容することが可能である複数の凹部５８を長手部材１２の周方向に離散的に並ぶ配列として含む。【選択図】図１
