本考案は支点を中間に設けた形式の鋏に関し、主として
プラスチックや金属のような硬質材の切断に好適ならし
めたものである。[Detailed Description of the Invention] The present invention relates to a pair of scissors with a fulcrum located in the middle, which is suitable for cutting hard materials such as plastics and metals.
ところで従来の中間支点形式の鋏は、把柄が支点軸の後
方に設けられているため切断時に手が邪魔になるので、
これを避けるために把柄を刃体に対してくの字形に屈曲
させた形式の鋏が（例えば実公昭４９−４５０３３号、
実開昭４９−８０４８３号公報等により）提案されてい
るのであるが、これらは何れも刃体に対して把柄が同一
方向に屈曲されているため一方の刃体が截断された左右
の切断材間を通過することになるのであり、従って紙や
布ならともかく硬質板では切断材が左右に押し開かれる
ことになって、硬質材の切断時に不都合をきたすのであ
る。By the way, with conventional intermediate fulcrum type scissors, the handle is installed behind the fulcrum shaft, so your hands get in the way when cutting.
To avoid this, there are scissors whose handles are bent in a dogleg shape toward the blade (for example, Utility Model No. 49-45033,
However, in both of these methods, the handle is bent in the same direction with respect to the blade body, so that one blade body is cut on the left and right sides. Therefore, whether it is paper or cloth or a hard plate, the material to be cut is pushed open from side to side, causing inconvenience when cutting hard materials.

ようにしたものである。In the present invention, the back edge of the base rod provided on one blade body is bent into a dogleg shape, whereas the base rod on the other blade body has an inner edge aligned with the blade edge. The above-mentioned disadvantages are eliminated by forming the blade so as to extend backward from the fulcrum shaft, and opening and closing the blade via a link.

杆２′が延出状に形成されている。The present invention will be described below with reference to the embodiment shown in the figure. Reference numerals 1 and 2 are blade bodies that are in mutual contact with each other, and one blade body 1 is attached to the rear base rod 3.
The blade edge 1', which is provided in a straight line, is bent in a dogleg shape toward the lower dorsal edge, and a handle 4 is provided on the extension part, and the other blade body 2 is shaped like a plate, and the blade body The base rod 2' is pivoted at a position near the bent part of the blade body 2 by a fulcrum shaft 5, and the base rod 2' whose inner edge is in line with the blade edge of the blade body 2 extends from the rear of the shaft 5. It is formed.

位置させるのである。6 attaches the mounting part 7 at the tip to the blade body 1 so as to make a pair with the handle 4.
The handle 9 has one end connected to the end of the base rod 2' located between the extended line of each blade edge of the blade bodies 1 and 2, and the above-mentioned shaft. Mounting part 7 close to 8
and are connected by pins 10 and 11, respectively, and
The thickness of the link is made approximately equal to or slightly thinner than the step 12 formed at the inner boundary between the blade body 1 and the base rod 3, so that the outer surface of the link 9 is positioned on the same plane as the inner surface of the blade body 1. Let it happen.
１３は把柄４，６を開き勝手に附勢するようその間に介

さしめうるのである。In the scissors of the present invention, when the other handle 6 is opened and closed with respect to the handle 4, the movement of the handle 6 is transmitted to the base rod 2' via the link 9, so that the blade 2 moves around the fulcrum shaft 5. It is opened and closed depending on the relationship with the mating blade 1 and can perform a cutting action.

めうるのである。However, according to the present invention, the base rod 3 of one blade body 1 is bent at the back edge so as to form a dogleg shape.
The base rod 2' of the other blade body 2 is extended to the rear of the fulcrum shaft 5 to which the two blade bodies 1 and 2 are pivotally attached, and its inner edge is formed in a straight line with the blade edge of the blade body 2. An end portion located between the rear extension lines of both blade edges of the base rod 2' is connected by a link 9 to a mounting portion 7 of the handle 6 which is pivotally attached to the back edge position of the blade body 1 by a shaft 8. Furthermore, since the outer surface of this link 9 and the inner surface of the blade body 1 are formed to be on the same plane, not only does the handle not become an obstacle during the cutting operation, but also the left and right cut materials are placed in contact with the blade body, respectively. Since it can be guided backwards along the surface and in the direction of the arrow shown in the straight line of each blade edge, it eliminates the disadvantages of bending during cutting or pushing the cut material apart from side to side as the blade passes through it. This makes it suitable for cutting hard materials.
