Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to cutlery such as knives, kitchen knives, scissors, etc., and specifically relates to the structure of the blade portion.

(Prior Art) Amorphous alloys, polymer fibers, carbon fibers, and piano wires have excellent properties in terms of strength, hardness, and toughness. Therefore, in recent years, attempts have been made to apply the various materials mentioned above to materials for cutlery.

(Problems to be Solved by the Invention) However, with the current manufacturing technology for the various materials mentioned above, although thin plate-like bodies such as linear bodies and foils can be easily manufactured, it is difficult to manufacture thick plate-like bodies. However, there is a constraint that the manufacturing cost increases rapidly.

Therefore, in order to apply the above-mentioned various materials to materials for cutlery, there are problems that the plate thickness is too thin and the cost is too high.

Structure of the Invention (Means for Solving the Problems) Therefore, in order to solve the above-mentioned problems, the present invention includes a plurality of linear bodies extending in a direction intersecting the longitudinal direction of the sword blade. A technical measure was taken in which they were arranged almost closely to form an assembly, reinforcements were provided on both sides of the assembly, and blades were formed at the edges of the assembly.

(Function) By arranging a plurality of linear bodies extending in the direction intersecting the longitudinal direction of the blade almost closely in the longitudinal direction of the blade, it is possible to easily and inexpensively produce an aggregate having a thickness suitable for use as a cutlery. be able to.

Further, the reinforcing bodies provided on both sides of the assembly serve to reinforce the assembly and maintain the shape of the blade.

Further, since the aggregate is almost completely closed, a continuous blade can be formed by grinding the edges. Moreover, since fine undulations are formed at the tip of the formed blade in accordance with the pitch of the aggregate, these undulations improve the sharpness of the blade.

(Example) Hereinafter, an example in which the present invention is embodied in a knife for eating and drinking will be described with reference to FIGS. 1 to 3.

A horizontally long blade 3 is integrally formed at the tip of a handle 1 made of stainless steel. This blade 3 is composed of an assembly 5 of linear bodies 4a and 4b made of an amorphous alloy as a high-strength material, and reinforcing bodies 6 provided on both sides thereof.

As shown in FIG. 3, a plurality of linear bodies 4a made of an amorphous alloy and extending in a direction intersecting the longitudinal direction of the blade 3 are arranged in the longitudinal direction of the blade 3. Another linear body 4b, also made of an amorphous alloy, extends in the longitudinal direction of the blade 3 and is disposed at right angles to the linear body 4a. Both linear bodies 4a and 4b are woven into a plain weave to form a net-like body 5 as an aggregate. In this net-like body 5, the distance between the linear bodies 4a and 4b is small, and the meshes are almost tightly packed.

The edges of this net-like body 5 are subjected to a grinding process. That is, the lower ends of the linear bodies 4a, 4b are sharpened by cutting and polishing, and a continuous blade 2 is formed as a whole. At this time, the blade 2 is formed with fine undulations A corresponding to the intervals of the meshes of the net-like body 5.

Examples of the amorphous alloy include iron and boron, iron and phosphorus, iron, boron and phosphorus, iron, silica and boron, cobalt and boron, cobalt, phosphorus and boron, cobalt, silica and boron, nickel and phosphorus, and nickel and phosphorus. It is appropriate to use nickel, silica, and boron, or nickel, silica, and boron. Also,
The linear bodies 4a and 4b are formed to have a diameter of about 0.5 mm from the melt of the amorphous alloy by spinning in a rotating liquid, and have excellent strength and hardness as well as toughness.

As shown in FIG. 2, reinforcing bodies 6 made of high-strength synthetic resin, such as polycarbonate resin, polyphenylene oxide resin, polyacetal resin, etc., are provided on both side surfaces and the top surface of the net-like body 5 described above. . That is, the net-like body 5 is embedded in the reinforcing body 6 by injection molding the various synthetic resins described above using the net-like body 5 as an insert. At this time, the reinforcing body 6 has entered between the meshes of the net-like body 5 and is reinforcing the same net-like body 5.

Next, the operation and effects of the embodiment configured as described above will be explained.

The amorphous alloy linear bodies 4a and 4b have a diameter of about 0.5 mm and are relatively thin, so they can be easily and inexpensively obtained using conventional manufacturing techniques. Therefore, a plurality of linear bodies 4a made of an amorphous alloy and extending in a direction intersecting the longitudinal direction of the sword blade 3 are arranged in the same longitudinal direction, and a linear body 4b is further arranged in a direction perpendicular to the longitudinal direction of the blade 3 to form both linear bodies. By knitting 4a and 4b, a net-like body 5 having a thickness suitable for use as a cutlery can be prepared and manufactured at low cost.

Further, the net-like body 5 manufactured in this way is reinforced by insert injection molding of a high-strength synthetic resin on both sides thereof, and the shape of the blade 3 is maintained.

The blade 2 of the net-like body 5 has the characteristics of an amorphous alloy, that is, has good strength, hardness, and toughness, and exhibits excellent cutting ability. Further, the blade 2 is not easily corroded and can maintain its sharpness for a long period of time.

Since the blade 2 has fine undulations A corresponding to the spacing between the meshes of the net-like body 5, it can be easily caught in the undulations A, resulting in a sharper blade.

It should be noted that the present invention is not limited to the configuration of the above-mentioned embodiments, and may be modified and embodied as desired without departing from the spirit of the invention, for example, as described below.

(1) The assembly 5 may be formed by arranging linear bodies 4a made of an amorphous alloy and extending in a direction intersecting the blade 3 only in the longitudinal direction of the blade 3. This eliminates the need for the step of weaving the linear bodies 4a, 4b, making it possible to form the blade 3 more easily and inexpensively.

(2) When forming the blades 2 on the edges of the net-like body 5, the edges may be rolled in advance, which makes it possible to reduce the mesh size of the net-like body 5 and to prevent cutting, polishing, etc. Grinding becomes easier.

(3) The linear body is not limited to the amorphous alloy linear body, but carbon fiber or piano wire may also be used.

(4) For the reinforcing bodies 6 provided on both sides of the assembly 5, general steel materials such as stainless steel may be used in addition to synthetic resin.

(5) The present invention is not limited to knives for eating and drinking, but can be embodied in knives such as paring knives and folding knives, or various cutlery such as kitchen knives, scissors, and nail clippers.

Effects of the Invention As described in detail above, the cutlery of the present invention has excellent effects in that the blade has excellent strength, hardness, and toughness, has good sharpness, and can be manufactured easily and inexpensively.
