PROBLEM TO BE SOLVED: To provide a manual work tool structured to impose a light burden on the body while managing with one tool according to three kinds of main work purposes because conventional tools such as a sickle, a hoe and a rake used for gardening work such as weeding are separate tools properly used for the respective purposes, and a tool integrating a sickle and a rake into one is heavy as a whole, and different kinds of blades face separate directions from each other and are not well balanced in weight applied to work so that extra power is often applied on the body.SOLUTION: Three thin and lightweight L-shaped blades made of metallic flat bars and hard to rust are laminated in three stages and mounted to a handle, and the three blades are closed/opened in sector shape so as to be adjustable in mutual space and switchingly usable as the sickle, hoe and rake according to the purpose.COPYRIGHT: (C)2014,JPO&INPIT【課題】従来、草取り等の園芸作業に使う鎌、鍬、熊手等の用具は、それぞれ用途別に使い分ける別々の用具であった。鍬と熊手が1個にまとめてあるものは、全体が重く、別種類の刃が相互に別方向に向いているため、作業にかかる重さのバランスがとれず、身体に余分な力を強いることが多かった。主な3種類の作業用途に応じて、1本の用具で済ませる、身体にも負担の軽い構造の手作業用具を提供する。【解決手段】錆びにくく、細く軽量の3本の金属平棒製のL型状の刃を3段重ねにして柄を取付け、3本の刃を扇状に相互の間隔調整自在に締め開きして、カマ、クワ、熊手として、用途に応じて自由に使い替えできることを特徴とするカマ、クワ変幻熊手。【選択図】図2
