本発明は、刃角度を小さくして切れ味を良好にせしめた
ジグザグ鋏に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to zigzag scissors with a small blade angle to improve sharpness.
第４図に示されるように、ジグザグ鋏のジグザグ刃１１

くなって鋏の調子成るいは切れ味が低下する。As shown in FIG. 4, the zigzag blade 11 of the zigzag scissors
The blade angle α' is functionally close to a right angle, and scissors, including zigzag scissors, cut the object by the shearing action of a pair of iron plates with low force, and the smaller the blade angle, the better the scissors are. The sharpness is good. Also, the cutting edge of the zigzag blade 11 has an angle β'
Most of the blades are around 85 degrees, and even if the angle β' is reduced, the blade angle α' does not become much smaller.
When the angle β' of the blade is made smaller, the angle formed by the pair of iron plates during cutting (hereinafter referred to as the cutting angle) becomes smaller, and the tone or sharpness of the scissors deteriorates.

しめたことである。The present invention has been made in view of the above-mentioned circumstances, and the gist thereof is that blade portions are provided facing inward at the inner ends of a pair of iron plates that are pivotally connected by a bottle, and each blade portion has a zigzag pattern. In the zigzag scissors provided with blades, the cross-sectional shape along the length direction of the iron plate is arc-shaped in the square-shaped part formed by the zigzag blade on the outer surface of at least one of the blade parts. By providing the concave portion, the blade angle of the zigzag blade is made smaller, thereby improving the tone and sharpness of the zigzag scissors.

角である。1 to 3, a pair of iron plates 1 are pivotally connected via a pin 2, and a blade part 3 is provided at the inner end of each iron plate 1 facing inward, and each blade part 3 is provided with a zigzag blade 4. As is clear from FIG. 3(d), the blade angle α of the zigzag blade 4 before the four portions 5 described later are provided is approximately a right angle.

グザグ刃４の刃付は角βは、８５°前後である。Then, according to the present invention, each chevron-shaped portion formed by the zigzag blade 4 on the outer surface 3 & of the blade portion 3 of both iron plates 1 is ground with a grindstone, so that the cross-sectional shape along the length direction of the iron plate 1 is circular. Four arcuate parts 5 are provided. Therefore, as is clear from FIG. 3, the blade angle α of the zigzag blade 4 is smaller than the blade angle α' of the conventional zigzag blade. Incidentally, the angle β of the zigzag blade 4 is approximately 85°.

刃角度を小さくしてもよい。Alternatively, the four parts 5 having the above structure may be provided on the outer surface 3a of each blade body part 3 of one iron plate 1, and the blade angle of the zigzag blade 4 of only one iron plate 1 may be made small.

ができる。As described above, the zigzag scissors according to the present invention has a zigzag portion formed by the zigzag blade 4 on at least one outer surface 3a of each blade body 3 of a pair of iron plates along the length direction of the iron plate 1. The blade angle of the zigzag blade 4 is reduced by providing four parts 5 with an arcuate cross-sectional shape. Even if the cutting angle is made smaller, the cutting angle does not become smaller, and therefore the sharpness of the zigzag scissors can be further improved.
