Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to scissors, and particularly relates to the structure of the finger grip.

[Prior art and problems to be solved by the invention] Generally, in order to cut a long object such as paper or cloth straight without a mark, the cut edge of the object should be placed on the finger grip side of the scissors. It is desirable to position it on the same straight line as the blade. However, since conventional scissors do not have a part that properly guides the cutting edge of the object to be cut, the cutting edge is obstructed by the finger hook or fingers, making it very difficult to cut straight lines without markings.

An object of the present invention is to provide scissors that can guide the cutting edge of the object to be cut straight along the extension line of the blade, making it easy to cut in a straight line without markings. .

[Means for Solving the Problems] Therefore, in order to achieve the above-mentioned object, the present invention provides a method for attaching an object to be cut to a finger hook of at least one of a pair of scissors pieces pivotably attached to the scissors pieces so as to be openable and closable. The gist of the scissors is a pair of scissors in which a guide part for guiding the cutting edge is formed so as to extend approximately along the extension line of the blade of the scissor piece in substantially the same plane as the inner surface of the scissor piece. be.

[Operation] According to this solution, since the cutting edge of the object to be cut is guided straight along the extension line of the blade,
Straight cuts without marks become easier.

[Example] Hereinafter, an example that embodies this invention will be described as follows.
This will be explained based on FIG.

In FIG. 1, reference numeral 1 denotes a first scissor piece, on the proximal end of which is provided a finger hook 3 made of synthetic resin having a hole 2 for hanging the thumb, and
A blade portion 4 is formed on the tip side. Reference numeral 5 designates a second scissor piece, the proximal end of which is provided with a synthetic resin finger hook 7 having a hole 6 for hanging the index finger and middle finger, and a blade portion 8 formed on the distal end. There is. The scissor pieces 1 and 5 are pivotally connected to a shaft 9 so as to be openable and closable, and the blade parts 4 and 8 cooperate to cut an object P such as paper or cloth.

As shown in FIGS. 2 and 3, on the outer surface (left side in FIG. 3) of the finger hook 3 of the first scissor piece 1,
Guide part 1 for guiding the cutting edge A of the object to be cut P
3 is formed. The guide portion 13 in this embodiment includes a support surface 14 that extends substantially along the extension line of the blade portion 4 of the first scissor piece 1, and a guide surface that is located in substantially the same plane as the inner surface 1a of the first scissor piece 1. The support surface 14 supports the lower surface of the cut edge of the object P, and the guide surface 15 guides the cut edge A.

Therefore, when cutting the object P using the scissors configured as described above, one cutting edge A of the object P must be placed along the guide portion 13 with the hand not holding the scissors. , Cut the scissors while opening and closing both scissor pieces 1 and 5. At this time, the pair of cutting edges A and B of the object to be cut P contact the guide portion 13 and the fingers of the hand holding the scissors, respectively, as the scissors pieces 1 and 5 open and close, and move in the vertical direction. It can be expanded greatly.

When you cut the scissors in this way, the object to be cut P
One of the cutting edges A is guided in the same straight line as the blade part 4 by the inner surface 5a of the second scissor piece 5 and the guide surface 15, so the cutting edge A is distorted even when making a long cut. There is no fear. Moreover, since the thumb is always located below the guide section 13, the object to be cut P can be smoothly sent out to the front side without being hindered by this.

Incidentally, it is also possible to perform the cutting operation in the same manner as described above by holding the scissors upside down so that the guide portion 13 is at the bottom, as shown in FIG. That is, while aligning the cut edge B with the guide portion 13,
Hold the cutting edge A with the hand that is not holding the scissors and continue cutting with the same scissors. Then, both cut edges A and B are not obstructed by fingers or finger hooks 3 and 7, and the first
Similarly to the figure, the object P can be easily cut in a straight line. This is particularly effective when cutting objects P having high rigidity such as cardboard, resin plates, thin metal plates, and the like.

5 and 6 each show another example of the guide section. The guide section 16 shown in FIG. 5 is formed into a U-shape in cross section, and includes a support surface 14 and a guide surface 15 similar to those shown in FIG. have. The guide portion 18 shown in FIG. 6 has a V-shaped cross section, and its bottom edge extends approximately along the extension line of the blade portion 4 of the scissor piece 1.

In addition, it is also possible to form the guide part in both finger-rest parts.

[Effects of the invention] As detailed above, according to this invention, the cutting edge of the object to be cut is guided straight along the extension line of the blade, making it easy to cut straight lines without marks. It has this excellent effect.
