Description

[Detailed description of the invention] Technical field The present invention relates to scissors and a method for manufacturing the same.

Object The object of the first invention is to provide scissors that are easy to manufacture but have a completely novel appearance, and the object of the second invention is to provide scissors that are easy to manufacture and suitable for manual production. The method is to provide cover.

Structure To achieve the above-mentioned object, the first invention of the present application curves a wire into an annular shape to form and cover the grip, gives spring properties to the grip, and rolls both ends of the wire of the grip. There is an invention in which the entire pair of scissor pieces are integrally formed, and the second invention has both ends of a wire having spring properties [approximately 111
(Bend each corner in the same direction, roll the bent part of each bar to form a pair of scissor pieces, curve the wire part between both scissors into an annular shape to form a grip part, and then There is C, in which the pieces are arranged in such a way that they can cooperate with each other.

EXAMPLE Hereinafter, an example embodying the present invention will be described with reference to FIGS. It is formed by The outer diameter of this grip part 1 is large enough for an adult to hold with one hand! (The size is 8-9 cm in practical use, which is enough to fit one door in the first instep), and the grip part 1 is also shortened? It has spring properties in the Y direction. 2 is this circular shape! 1) There is a finger ring C formed near one end of the grip part 1 at the t part, and a ring C for the grip part 1 is formed so as to protrude to the inner side of the grip part 1. It is formed by winding the wire once. This finger rest (inner diameter LL "f" lJt of the ring 2 is large enough to comfortably fit the thumb of a person with small hands or the index finger of an adult, and is 2 to 2.5 cm in actual size).

Reference numeral 3 denotes a pair of scissor pieces integrally formed at both ends of the grip portion 1, and the tips of both of the scissors pieces protrude inside the grip portion 1. Further, these scissor pieces 3 are arranged in a diagonal shape with respect to each other so that the tips *η; of their respective blade parts 4 intersect six times.

Now, when using the scissors configured as shown in the above, hold the grip part 1 in your hand and hold the pair of points (A) (B) Grip tightly with the other three or four fingers. Then, as shown in FIG. 3, the grip part 1 contracts in diameter against its own elasticity, and the pair of scissor pieces 3 intersect with each other. Then, both scissor pieces 3 are closed and the object is cut by these blades 4. After cutting, if you loosen your grip on the grip part 1, the grip part 1 will release due to its own elasticity.
c Returns to the original large diameter state, and at the same time, the [
Listen to Yosami Piece 3 and return to the original position.

In addition, when using scissors in this way, B of grip part 1
If you put 4 or 3 fingers other than your thumb on the part, 2\
In this case, the index finger of these fingers may be inserted into the finger ring 2. In this way, use 11 is to use scissors by a person;
(b) You can do other tasks with your fingertips while keeping the scissors on your fingers, and there is no need to take the trouble of removing the scissors from your fingers for this task.

By the way, if you have small hands such as children and cannot hold the entire body of the grip part 1, use the above-mentioned 1 yen 8 no ↑ I = J' [2] on the inside of the grip part 1. , and place the other four fingers on the outside of the Δ part of the 114th part 1.

The scissors mentioned above are composed of a grip part 1 made of curved wire and a scissor piece 3 integrally formed with the grip part 1, so its structure is extremely easy to manufacture using IJA. The exterior is completely new and comes in 4L. In addition, with this pair of scissors, the tips of the pair of tit scissors J3 are all directed towards the inside of the grip part 1 (Jj), so the tips of the scissors do not protrude outward, so the tips of the scissors come in contact with the hands while handling the scissors. 73 dangers can be prevented.

Next, in October, 1st! lllll method 1st and 4th to 6th
As explained below with reference to the figure, first the wire is cut to a predetermined size. This wire rod is made of a springy stainless steel material (for example, 5US304), and its thickness is 2 to 5 m0), preferably 2.5 to 3 mm and 10 mm. Next, both ends of the cut wire rod 18 are bent in the same direction as shown in FIG.
Each bending angle θ is approximately 80°. After bending, it is shown in Figure 5. +', J: sea urchin double folded part 3
Press and crush a and its proximal end (= near J, and make each width W 5 to 8 mm and thickness 0.3 to 0.7 mm.J3, when pressed in this way, it will bend on both sides. part 3
a slightly expands outward, and the bending angle θ is approximately 9°.

After pressing, the sea urchin is bent on both sides 3a as shown in Figure 6.
is formed by grinding or pressing and formed into a pair of scissor pieces 3, and each scissor piece 3 is made with a blade (J-grinder) to form a blade portion 4.

Thereafter, the wire rod 18 shown in FIG.
Furthermore, the JIZ portion 1 is formed by curving it into a large annular shape. At this time, the pair of scissor pieces 3 are made to protrude inward from the grip part 1, and the tip 9i of each blade part 4 is
7. Slightly cross the edges to create a diagonal shape.

Then, the surfaces of both scissor pieces 3 are polished or polished to finely adjust the engagement of the blade portions 4.

With this, nAB of L width is completed.

If one size of scissors is manufactured as described above, this manufacturing can be easily carried out, and moreover, it is possible to produce a large number of scissors in 11 days.

Another Embodiment The grip part 1 in the above-mentioned example M1 is formed not in a circular ring shape but in a polygonal ring shape such as a triangular ring shape or a square ring shape, or an elliptic ring shape. Also, for the finger rest, the ring 2 is formed separately from the 1st floor part 1, and the ring 2 is formed separately from the 1st part 1. It may be fixed to the grip part 1, or it may be provided outside the grip part 1 as shown in FIG. Furthermore, the finger ring 2 is not completely annular, but may have a partially circular shape as shown in FIG. It is also possible to change it to , or to set up more than one.

Effects As detailed above, the first invention of the present application has the effect of being able to manufacture scissors at a low cost and giving it a completely novel appearance, and the second invention has the effect of being able to manufacture scissors at a low cost and giving it a completely novel appearance.
Since the present invention has effects suitable for production, it is a practically preferable invention for scissors and a method for manufacturing the same.
