Description
【0001】0001
この考案は薄い刃板からなる刀身、並びにその刀身をホルダに対し出入可能に 支持したカッターに関するものである。 This idea has a blade made of a thin blade plate, and the blade can be moved in and out of the holder. It concerns the supported cutter.
【0002】0002
従来、壁材を貼る場合には、各壁材の端縁部を互いに重ね合わせ、その重合部 分をカッターの刀身により切断して各壁材の端縁を互いに接触させるようにして いた。この場合、各壁材の裏面に付けられている接着剤が刀身に付着すると、切 断縁が刀身から離れにくくなり、切断操作に支障を来たすおそれがあった。 Conventionally, when pasting wall materials, the edges of each wall material are overlapped with each other, and the overlapping area is Cut the sections with the blade of a cutter so that the edges of each wall material touch each other. there was. In this case, if the adhesive attached to the back of each wall material adheres to the blade, it will cause a cut. There was a risk that the cutting edge would be difficult to separate from the blade, which would impede the cutting operation.
【0003】 また、従来のカッターとしては、刀身をホルダ内に挿入してホルダに対し出入 可能に支持したものがある。このようなカッターにおいては、ホルダの刀身出入 口の両内面と刀身の両側面との間に隙間があると、ホルダに対し刀身が振れて使 いにくい。逆に、刀身の両側面が刀身出入口の両内面間で隙間なく挟持されると 、ホルダに対する刀身の出入抵抗が大きくなって刀身の動きが円滑に行われない 。0003 In addition, as a conventional cutter, the blade is inserted into the holder and moved in and out of the holder. There are things that could be supported. In such a cutter, the blade of the holder cannot be moved in and out. If there is a gap between both inner surfaces of the mouth and both sides of the blade, the blade will swing against the holder and will not be used. It's difficult. On the other hand, if both sides of the blade are sandwiched between both inner surfaces of the blade entrance and exit, there is no gap between the two sides of the blade. , the resistance of the blade moving in and out of the holder increases, making it difficult for the blade to move smoothly. .
【0004】0004
このように従来の問題点は刀身に対する切断縁の離れが悪い点と、ホルダに対 し刀身が振れたりホルダに対する刀身の動きが悪い点にあり、本考案は刀身の両 側面の形状を改良してこのような問題点を解決することを目的としている。 In this way, the problems with the conventional method are that the cutting edge is not far enough away from the blade, and that it is difficult to hold the holder. However, the problem with this is that the blade swings and the movement of the blade relative to the holder is poor. The aim is to solve these problems by improving the shape of the side surfaces.
