〈産業上の利用分野〉
本発明は、作業工具用ケースに関し、特に作業工具を簡
単かつ確実に収納保持し得る作業工具用ケースに関する
。DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to a case for a power tool, and particularly to a case for a power tool that can easily and reliably store and hold a power tool.
〈従来の技術〉
従来、ドライバやレンチ等の作業工具は、単に収納する

実に保持されていないので、意に反して躍ってしまい、
ケース内で相互に衝突して騒音を出したり、損傷を生じ
たり、さらにはばらばらになってしまい、使用に際して
目的寸法の同工具を直ちに見つけ難い等の欠点があった
。<Prior Art> Conventionally, work tools such as screwdrivers and wrenches have been stored or engaged in cases that are simply stored or holders that are simply engaged. Therefore, since these cases and holders are only intended for storage or engagement, when carrying them, the tool is not held securely within the case and may be used against your will. I jumped,
They collide with each other within the case, causing noise, damage, and even falling apart, which has the disadvantage of making it difficult to immediately find the same tool of the desired size when using it.
このため、従来ばねや弾性材等の弾発力を利用して同工
具を保持する手段を備えたケース等があったが、構造が
煩雑となり、しかもコストが大幅に上昇する等の欠点が
あるため、実用性に乏しかった。For this reason, conventional cases have been equipped with a means to hold the tool using the elastic force of a spring or elastic material, but these have disadvantages such as a complicated structure and a significant increase in cost. Therefore, it lacked practicality.
また、同工具を挿入可能な孔の内壁に同工具に係合可能
な突起を設け、該突起に同工具を係合することによって
保持するものが提案されたが、型製作上および加工上難
点があるばかりでなく、加工精度が要求され、しかも小
面積で保持を担当するため、同突起が長期の使用によっ
て摩滅を生じ、次第に保持力が低下してしまうという問
題点があった。It has also been proposed to provide a protrusion that can engage the tool on the inner wall of a hole into which the tool can be inserted, and to hold the tool by engaging it with the protrusion, but this poses difficulties in mold manufacturing and machining. Not only that, but also machining precision is required, and since the holding is done over a small area, the protrusions become worn out over long periods of use, resulting in a gradual decline in holding power.
また、同化の形状が円形であるため、六角形等の非円形
断面に形成された軸を有する作業工具の挿入方向が同孔
の入口を見ただけでは判別し難く、挿入方向を間違えて
挿入してしまうことが多々あり、同孔の軸方向の途中に
ある係止突起に不本意に係合してしまい、扱い慣れしな
い作業者等はそのまま挿入し易く、ケースを損傷する虞
れがあった。さらに、この場合には、同孔への作業工具
の挿入方向を確定するのに時間がかかる等、取扱いが煩
雑であるという問題点があった。In addition, since the shape of the assimilation is circular, it is difficult to determine the insertion direction of a power tool with a shaft formed in a non-circular cross section such as a hexagon just by looking at the entrance of the same hole, and it may be difficult to insert the tool in the wrong direction. This often results in the case being accidentally engaged with the locking protrusion located midway in the axial direction of the same hole, making it easy for workers who are not accustomed to handling the case to insert it as is, which may cause damage to the case. Ta. Furthermore, in this case, there are problems in that it takes time to determine the direction in which the working tool is inserted into the hole, and the handling is complicated.
