Description

[Detailed Description of the Invention] This invention relates to a kitchen knife, and its purpose is to provide a kitchen knife whose base portion can be easily assembled.

The first embodiment embodying this idea is shown in Figures 1 to 3 below.
To explain the figure, in this embodiment, a rectangular tongue piece 3 is integrally formed below the core 1 and protrudes rearward from the base end of the blade 2, and between the core 1 and the tongue piece 3. An insertion gap 4 having a rectangular shape and open at the rear is formed in the opening.

A sharp biting protrusion 3a is formed at the rear end of the tongue piece 3.

Attachment grooves 6 and 7 are formed in the upper and lower parts of the cap member 5 fixed at the front end position of the core 1, respectively, and a sandwiching part 8 is formed between the two grooves 6 and 7.

Then, in this cap member 5, the core 1 and the tongue piece 3 are respectively fitted into both the grooves 6°7, and the inserting portion 8 is inserted into the inserting gap 4, so that the front end position of the core 1 is Fixed.

Further, the material of the cap member 5 may be arbitrarily selected from metal, synthetic resin, reinforced wood, etc. as required.

A handle 9 is provided at the rear of the cap member 5 and is fixed to the core 1 with rivets 10.

This grip handle 9 has a different color from the base member 5.

Note that the core 1 has a narrow front end portion and a wide portion where the studs 10 are fixed.

Now, in order to assemble the knife configured in this way, the inserting part 8 is inserted into the inserting gap 4 so that the core 1 and the tongue piece 3 are fitted into both the grooves 6 and 7 of the cap member 5. Push in from the rear so that it is inserted into the holder.

In this case, it is preferable to interpose an adhesive between the core 1 and the tongue piece 3 and the inner surfaces of the grooves 6.1. It may be attached to the core and fixed with studs 10 so that the protrusion 3a bites into it and the front end presses against the rear end surface of the cap member 5.

In this way, the grip handle 9 can be manufactured very easily without providing a stepped portion for fitting the cap or fixing the cap by welding.

Next, a second embodiment of this invention will be explained with reference to FIG. 4. This second embodiment differs from the first embodiment in that the core 1 is formed into a simple rectangular shape.

Next, the third embodiment will be explained with reference to FIGS. 5 and 6. In this embodiment, the inner side of the tip of the core 1 is obliquely shaped so that the insertion gap 4 is gently tapered. be.

As shown in FIG. 5, the insert portion 8 of the base member 5 is not oblique.

Therefore, as the inserting portion 8 is inserted into the inserting gap 4, the inserting portion 8 is compressed by the core 1 and the tongue piece 3, so that the cap member 5 can be more firmly attached.

This oblique portion may be provided on the tongue piece 3, or may be provided on both 1 and 3 as shown in FIG.

Furthermore, although not shown, the tongue piece 3 may be located above the core 1.

The functions and effects of these second and third embodiments are the same as those of the first embodiment.

As exemplified in the embodiments above, this invention is a kitchen knife in which the base member is fixed at the front end position of the core, so that a inserting gap that opens toward the rear is formed between the knife and the core.
A tongue piece is integrally formed to protrude rearward from the base end of the blade, and mounting grooves are formed on the top and bottom of the base member into which the core and tongue piece are respectively fitted, and between the mounting grooves there is formed a tongue piece. By forming the insertion part that is inserted into the insertion gap,
This provides an excellent effect in that the base part can be assembled extremely easily.
