WORK BENCH
To provide a work bench provided with a handrail frame pivoted on a working floor and rotatable between a standing position and a horizontal position, which avoids a situation in which the handrail frame cannot keep its standing position by disengagement of an engaging piece from an engaging pin caused by elastic deformation of a spring of an engaging device due to an impact generated on the handrail frame upon standing.SOLUTION: A work bench is provided with: first engaging pins P1 fixed on a handrail frame 52; second engaging pins P2 attached on a work floor 51 parallel to the first engaging pins P1 when the handrail frame is at a standing position 52A; and a connection device CL connecting the first and second engaging pins in a parallel state, wherein the connection device is provided with: engaging pieces 61 engageable with the first and the second engaging pins; connection members 62 with which the engaging pieces are slidably connected within a specific range; a spring 63 arranged between the connection member and the engaging piece to energize the engaging piece in an engaging direction with the first engaging pins; and a holding mechanism 60 capable of switching to an active state where the connection member is held at a specific position so as to allow the engaging piece to be held at engaging positions with the first and the second engaging pins with energized force of the spring.SELECTED DRAWING: Figure 6
【課題】作業床に軸支されて起立位置と伏倒位置との間で回動可能な手摺り枠を備えた作業台において、起立時の手摺り枠に生じる衝撃に結合装置のスプリングが連動して係合片が係合ピンから外れ、手摺り枠が起立保持できなくなる事態を回避する。【解決手段】手摺り枠５２に固定の第１係合ピンＰ１と、手摺り枠が起立位置５２Ａにあるときに第１係合ピンＰ１と並列するよう作業床５１に取付けられる第２係合ピンＰ２と、並列状態の第１，第２係合ピン間を結合する結合装置ＣＬとを備え、結合装置は、第１，第２係合ピンと係合可能な係合片６１と、それが所定範囲内で摺動可能に連結される連結部材６２と、連結部材と係合片間に設けられて係合片を第１係合ピンとの係合方向に付勢するスプリング６３と、スプリングの付勢力で係合片を第１，第２係合ピンとの係合位置に保持し得るよう連結部材を所定位置に保持する作動状態に切替え可能な保持機構６０とを備える。【選択図】 図６
