Abstract

(57) [Abstract] [Purpose] The purpose of the present invention is to provide scissors capable of easily cutting an object that is difficult to cut with conventional scissors by improving the cutting ability of the scissors for cutting the object. To do. According to the present invention, in a scissors having a single-edged blade, an inclined guide portion 5 having a thick back portion 4 side between the blade portions 3 and 4 and a thin blade portion 3 side on the surface of the blade portion 1 is provided. In the case of a push-cut scissors having a concave arc surface and a double-edged cutting blade body 7, the back side 9 side between the blade portion 8 and the back portion 9 is thick on both the front surface 7 ₁ and the back surface 7 ₂ of the cutting blade body 7. The slant guide portions 10 and 10 each having a thin wall portion on the side of the blade portion 8 are concave arc surfaces.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to scissors for cutting various cut objects.

[0002]

[Prior art]

 As shown in FIG. 4, there are many known inclining guide portions of the blades of various scissors that have been conventionally used, such as those with a salient arc shape commonly referred to as a clam-shaped figure 4a or a linear figure 4b.

[0003]

[Problems to be solved by the device]

 As is apparent from FIGS. 4A and 4B, the conventional scissors described above have a considerably large plate thickness of the blade portions 1 and 1, so that it is attempted to cut an object to be cut, particularly a thick one or a large diameter one. In doing so, the projected area of the blade parts 1 and 1 on the object to be cut becomes large, and the cutness to the object to be cut is lacking in smoothness so that it cannot be said that it is sharp scissors. It was In view of the above, the present invention intends to provide scissors having sharpness and good sharpness.

[0004]

[Means for Solving the Problems]

Since this invention is to achieve the above object, in the scissors of two blades scheme, it superimposed the blade body portion 1 and the first single-edged shape as the rear surface 1 ₁ and 1 ₁ face each other, moreover the blade body 1 1 and Although but is intended to the scissors cut by the axial stop has been blade body portion 1 and 1 by the shaft 2, in this case, the blade part 3 and the back 4 of the blade unit 1 by the surface 1 ₂ side of the blade body 1 The slant guide part having a thin blade part 3 side and a thicker back part 4 side between is formed into a slant guide part 5 which is recessed in a concave arc shape. The thickness of the blade is reduced by denting both the front and back sides of the guiding portion 10 in a concave arc shape.

[0005]

[Action]

 The scissors of this invention have a great influence on the cutting of the cutting object when cutting the cutting object, and the plate thickness of the cutting blade is extremely thin, so when cutting into the cutting object, the resistance received from the cutting object is small, In addition, since the inclination guide parts 5 and 10 following the blade part 3 are concave arc-shaped, as soon as cutting starts like a projecting arc shape or a straight surface like the inclination guide part of the conventional blade body. In addition, the surface of the tilt guide contacts the cut edge of the cut object and requires a large amount of force to push the cut object apart, which reduces the cutting force and makes it difficult to cut. The force concentrates only on the incision, makes a deep incision into the cut object, and then when it approaches the back part 4, the tilt guides 5 and 10 contact the cut edge to push the cut object and push the blade part 3 better And That is, since the projected area of the blade of the present invention on the object to be cut is considerably smaller than the projected area of the blade of the conventional scissors, the resistance received from the object to be cut by the blade is remarkably reduced and strong cutting can be performed. In addition, the reinforcement against thinning the inclination guide portions 5 and 10 in the blade body portion 1 can prevent the back portion 4 from supporting the inclination guide portion and causing no bending or breakage.

[0006]

【Example】

 The first embodiment of the present invention is raw scissors, and the second embodiment is push-cut type loose cutting scissors. In addition to this, various kinds of scissors such as pruning scissors, trimming scissors, and sewing scissors are used. Of course it is okay.

As in the embodiment of the present invention, the semi-diameter γ of the concave arc-shaped inclination guide portions 5 and 10 of the blade body of the small scissors is about 75 mm, but this radius is not limited to that of the embodiment. It changes depending on the size of the shape and the thickness and hardness of the object to be cut.The point is that when the scissor blade body cuts into the object, a concave arc that does not hinder cutting It should be a face.

[0008]

[Effect of device]

 According to the invention as set forth in claim 1, when the cutting object is cut by the scissors formed by the combination of the single-edged blade bodies, each of the blade bodies 1 and 1 of the tilt guide portion 5 cuts into the cutting object of the blade portion 3. Since it significantly reduces the interference with the cutting, the blade portion 3 can smoothly cut into and out, and the sharpness is improved, so that the object to be cut can be satisfactorily cut.

The invention according to claim 2 is a push-cut type scissors in which the cutting blade body 7 is a double-edged shape, and is a major factor that hinders the cutting of the blade portion 8 when cutting an object to be cut. Further, the resistance of the inclined guiding portions 10 and 10 to the object to be cut is remarkably reduced, and the blade portion 3 easily cuts into the object to be cut, so that cutting with good sharpness can be achieved.
