CARRYING ARTICLE FALL PREVENTION TOOL
PROBLEM TO BE SOLVED: To provide a carrying article fall prevention tool which does not cause tensile force to act on a carrying article and can prevent large jumping in a case of dropping the carrying article from a hand.SOLUTION: A carrying article fall prevention tool includes: a first interference part 51 and a second interference part 52 provided on one among a case 1 and a reel 3, in a manner of forming radially-shifted steps to each other; a swinging piece 6 provided on the other among the case 1 and the reel 3; and an elastic body 7 that can elastically hold the swinging piece 6. The swinging piece 6 interferes with the second interference part 52 in a pull-out rotation process of the reel 3 to be swung and displaced in a direction capable of relatively displaced in a circumferential direction to the second interference part 52. When relatively passing an interference position with the second interference part 52 in the pull-out rotation process of the reel 3 and thereafter transferring to a winding rotation process, the swinging piece 6 is swung and displaced in a direction capable of engaging with a step part 53 formed by the first interference part 51 and the second interference part 52, by interfering again with the second interference part 52. Further, the swinging piece 6 is swung and displaced in a direction not engaging with the step part 53 in the winding rotation process of the reel 3, by being relatively displaced in the circumferential direction in a direction separating from an engagement position with the step part 53.SELECTED DRAWING: Figure 3
【課題】携帯物に引っ張り力が作用することがなく、万一携帯物を手から落としてしまった場合の大きな跳ね上がりも防止できる携帯物落下防止具を提供する。【解決手段】ケース１及びリール３のうち一方に互いに径方向の段差をもって設けられた第一干渉部５１及び第二干渉部５２と、他方に設けられた揺動片６と、揺動片６を弾性的に保持可能な弾性体７とを備え、揺動片６は、リール３の引き出し回転過程で第二干渉部５２と干渉することによって第二干渉部５２との円周方向相対変位が可能な向きに揺動変位され、リール３の引き出し回転過程で第二干渉部５２との干渉位置を相対的に通過した後、巻き取り回転に移行したときに第二干渉部５２との再度の干渉により第一干渉部５１及び第二干渉部５２による段差部５３に係止可能となる方向へ揺動変位され、段差部５３との係止位置から離れる方向へ円周方向相対変位させることによって、リール３の巻き取り回転過程で段差部５３に係止されない方向へ揺動変位される。【選択図】図３
