Abstract

(57) [Summary] [Purpose] To provide a kitchen knife that can efficiently perform chopping and the like. [Structure] A plurality of thin blades 2 each having a cutting edge 10 formed on one edge, and the side surfaces of each of the cutting edges are arranged so as to be substantially parallel to each other with a predetermined small gap. The handle portion 3 is provided with a coupling and fixing means 16 capable of integrally coupling and fixing the same in a use state such that the two are coincident with each other.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a kitchen knife that can be easily chopped for cooking vegetables, fish, meat and the like.

[0002]

[Prior art]

 There are many types of conventional knives that can be used according to the purpose. However, in that structure, one blade is usually fixed to the handle, and the shape of the blade is different.

[0003]

[Problems to be solved by the device]

 Chopping vegetables with a conventional kitchen knife is very time-consuming because it requires a large number of cuttings. Also, it takes time for a person who is not very familiar with kitchen knives, so chopping an onion will hurt the eyes and close the mouth. The present invention aims to provide a kitchen knife capable of efficiently performing chopping and the like.

[0004]

[Means for Solving the Problems]

 According to the present invention, a plurality of thin blades each having a cutting edge formed on one edge thereof and a plurality of thin blades are formed to be substantially parallel to each other with a predetermined small gap, and the side shapes of the respective cutting blades. It is characterized in that it comprises a handle portion having a coupling and fixing means capable of integrally coupling and fixing the same in a consistent use state and releasing the coupling and fixing. The number of blades depends on the thickness of the blade and the size of the small gap, but it is good practice to keep the positions of the blades on both outer sides within the range of the handle thickness that is convenient for gripping. 2 to 5 is good. The shape of the blade may be either a willow blade or a straight blade and is not particularly limited, but the thickness of the blade is preferably about 0.5 to 1.3 mm.

[0005]

[Action]

 This kitchen knife is used in a state in which each blade is connected and fixed by the connecting and fixing means of the handle, and is used in the same manner as an ordinary kitchen knife. Since there are multiple blades, it is possible to form as many cuts as the number of blades in one cutting operation, so the work efficiency improves as the number of blades increases. For the object sandwiched between the blade portions of the cut object, a rubber or synthetic resin fork-shaped object may be prepared in advance and scraped out. If there are many objects to be cut, the cut pieces are pushed in sequence and come out toward the back of the kitchen knife, so it is sufficient to start scratching. Further, if the fixing of the fixed coupling means can be easily released, the cut and released piece can be taken out as needed. If the connecting and fixing means is released, the blade can be sharpened and cleaned.

【Example】

 An embodiment of the present invention will be described with reference to FIG. The illustrated kitchen knife 1 includes three blade portions 2 and one handle portion 3. The blade part 2 has the same shape as the blade part of a normal knives knife, each has the same shape, the blade crossover is 180 mm, the thickness of the blade is about 1 mm when it is thick, and the cutting blade 10, It has a connecting portion 11 for the handle portion 3, and two screw insertion holes 12 are formed in each of the connecting portions 11. The handle portion 3 is made of wood or synthetic resin, and is provided with a groove 14 into which the three coupling portions 11 are inserted via two spacers 13 each having a thickness of 2 to 2.5 mm. A screw insertion hole 15 corresponding to 12 is formed through the handle portion 3 and the spacer 13, and counterbore portions are provided at both ends thereof. As the fixed coupling means 16, the coupling portion 11, the insertion holes 12 and 15, a screw 17 inserted into these, and a nut 18 screwed into the screw are provided, and the blade portion 2 is inserted into the groove 14 of the handle portion 3 as a spacer. The respective connecting portions 11 are inserted together with 13, and are fixedly connected by screws 17 and nuts 18.

For example, when the cabbage is finely cut, this kitchen knife 1 can cut efficiently with a cutting pitch tripled as compared with the case of the conventional kitchen knife. Also, when chopping vegetables, for example chopped onion, first cut from the appropriate direction and sliced, then cut this almost randomly through the whole and then the kitchen knife. If the material coming out from the spine side is cut at a right angle to the cutting surface, the number of times of cutting is one-third that of the conventional kitchen knife, and the same chopped material can be obtained. Finally, the cut object sandwiched between the blade portions 2 is removed. This can often be easily removed, for example, by hitting the back of the kitchen knife on the cutting board a few times. In some cases, a fork-shaped device that can be inserted into the gap between the blades 3 may be prepared and used. In addition to the above, it can also be used when making cuts in fish, meat, etc. and is extremely convenient for cutting bones of fish.

FIG. 2 shows a kitchen knife 1a according to another embodiment, which is different from the above embodiment in that the number of blades 2 is 5, and the other is substantially the same. Therefore, the same parts are designated by the same reference numerals and the description thereof is omitted.

Instead of the joining and fixing means 16 in the above embodiment, the joining portion 11 and the spacer 13 are formed in advance so as to have the same side surface shape as that of the handle portion 3. It is also possible to superimpose them, and further to superimpose a member made of wood or a synthetic resin for constituting a handle portion formed separately on both sides on the outside thereof, and to fix them by a screw penetrating them. In that case, instead of the spacer, the connecting portion 11 of the blade portion 2 may be formed thicker on both sides by half the thickness of the spacer. In this case, if the number of blades 3 increases, wood or synthetic resin members for forming the handle on both outer sides may be omitted.

[Effect of device]

 According to the present invention, it is possible to provide a kitchen knife that can easily and efficiently chop vegetables, chop vegetables, and cut fish bones.
