Description

[Detailed description of the invention] This invention relates to a structure for attaching the core and handle of a kitchen knife, knife, etc.

Conventionally, when attaching a bottom plate to the handle to fix a wooden, synthetic or resin handle to the core, the bottom plate was directly fixed with adhesive to the rear end of the handle, or the rear end of the handle was fixed with adhesive. A fitting protrusion is formed on the bottom part, and a fitting concave part is bored in the butt part, and the fittings are fitted and fixed together.

However, in the former case, this configuration has the drawback that it takes time for the adhesive to harden.
In the latter case, there were defects in that the handle dried and shrunk, or the fitting part became loose due to long-term use, causing the butt to come off the handle.

The purpose of this invention is to eliminate the above-mentioned defects, to securely fix the bottom plate to the handle, so that the bottom plate will not come off from the handle even after long-term use, and to be able to be installed with one touch. The purpose of the present invention is to provide a structure for attaching a core and a handle in a cooking utensil.

An example in which this invention is embodied in a kitchen knife will be described below with reference to the drawings.

Reference numeral 1 in the drawings indicates a knife main body, and as shown in FIG. 2, a rectangular locking hole 3 is transparently provided at the rear end of a core 2.

Reference numeral 4 denotes a cylindrical handle attached to the core 2 of the knife main body 1, into which a insertion groove 5 is formed from above along its longitudinal direction, or a core 2 is inserted and fixed therein.

6 is a fitting convex portion formed by cutting out the outer periphery of the rear end of the same pattern 4;
is an insertion hole drilled in the axial direction from the rear end surface of the handle 4, into which an insertion portion 14 of a butt 9, which will be described later, is inserted.

Reference numeral 8 denotes an annular base attached to the outer periphery of the tip of the handle 4, which fixes the handle 4 and the core 2 of the knife body 1.

Reference numeral 9 denotes a bottom plate having a T-shaped cross section attached to the rear end of the handle 4, and is cut from the top to the bottom along the longitudinal direction of the bottom plate, as shown in FIG. A fitting groove 11 into which the end portion is inserted is formed, and an annular fitting recess 12 into which the fitting protrusion 6 of the handle 4 is fitted is bored in the front surface of the head 10. .

Reference numeral 14 denotes a pair of cylindrical insertion portions formed at the center of the front end of the head 10 of the butt 9, which are provided with vertically penetrating cuts in the whole, and form a part of the clamping groove 11. The handle 4 is inserted into an insertion hole 7 formed in the handle 4.

Reference numeral 15 denotes a wedge-shaped locking piece that projects from one side of the locking groove 11 of the butt 9 and fits into the locking hole 3 transparently provided in the center plate 2, as shown in FIGS. As shown in D, the thickness increases from the top to the bottom, and the bottom edge 15a is locked in the locking hole 3, thereby connecting the bottom metal 9 to the handle 4 and the middle 2. It is designed to be fixed.

Next, a method of assembling the knife constructed as described above will be explained.

First, the cap 8 is inserted into the core 2 from the rear end of the core 2.

On the other hand, insert the insertion part 14 of the butt 9 into the insertion hole 7 of the handle 4, and fit it into the fitting protrusion 6 so that the fitting groove 11 of the butt 9 matches the insertion groove 5 of the handle 4. The mating recess 12 is fitted.

Then, the tip of the handle 4 is passed through the mouthpiece 8 attached to the core 2, and the core 2 of the knife body 1 is inserted into the handle 4 and the insertion groove 5 and the clamping groove 11 of the butt 9. to be pierced from above.

At this time, the lower edge of the rear end of the core 2 comes into contact with a locking piece 15 provided on one side of the clamping groove 11, and the core 2 is inserted downward while expanding the clamping groove 11.

Then, when the locking piece 15 is fitted into the locking hole 3 of the core 2, the butt plate 9 is integrally connected and fixed to the handle 4 and the core 2, and the assembly of the knife is completed.

In this way, the locking piece 15 provided in the locking groove 11 of the butt 9 that fits into the handle 4 is connected to the locking hole 3 provided in the core 2 of the knife body 1.
Since the bottom plate 9 is not only fixed to the handle 4 but also connected and fixed to the core 2, the bottom plate 9 will not come off from the handle 4. .

Furthermore, once the wedge-shaped locking piece 15 is fitted into the locking hole 3, the locking piece 15 will not come off from the locking hole 3 unless the locking groove 11 of the butt plate 9 is widened, and the locking piece 15 will be very firmly attached. Concatenated.

In addition, the core 2 only needs to be inserted from above into the insertion groove 5 and the attachment groove 11 of the handle 4 and the butt 9, and the locking piece 15 provided in the attachment groove 11 is wedge-shaped. When the core 2 is inserted, it is inserted and secured without being caught by the locking pieces 15, so that its installation is very simple.

Further, since the insertion portion 14 of the end piece 9 is fitted into the insertion hole 7 of the handle 4 and clamps the middle 2, the end piece 9 does not wobble.

Next, another example of this invention will be explained based on FIGS. 5 to 8.

Another example shown in FIG. 5 is one in which a wedge-shaped locking piece 21 is provided protruding from one side of the locking groove 11 of the butt 9, the thickness increasing from the front end to the rear end.

Therefore, in this embodiment, the core 2 is slid from the front end of the handle 4 into the insertion groove 5 and the insertion groove 11 along the longitudinal direction of the handle 4 into which the end metal 9 is fitted. Gold 9 locking piece 2
1 and the locking hole 3 of the core 2 can be fitted to each other.

The tail metal 9 is firmly fixed to the handle 4 as in the previous embodiment.

Another example shown in FIG. 6 has a substantially triangular pyramid-shaped locking piece 22 protruding from one side of the locking groove 11 of the butt 9, which increases in thickness from the front end to the rear end and from the top to the bottom. It is.

Therefore, in this embodiment, the middle 2 is the same pattern as the pattern 4.
This can be done in two ways: by inserting it into the insertion groove 5 from above the handle 4, or by inserting it into the insertion groove 5 from above the handle 4.

Moreover, the tail metal 9 is firmly fixed to the handle 4 as in the previous embodiment.

In another example shown in FIG. 7, a pair of insertion portions 14 protruding from the front end surface of the butt 9 are connected at their lower ends to form a connecting portion 23, and a hooking groove is formed in the head 10. 11 in a shallower shape.

Therefore, even if the vertical width of the core 2 is small, the bottom metal 9 can be securely clamped and fixed to the core 2 without wobbling.

In another example shown in FIG. 8, an engagement groove 24 is formed in the lower central part of the rear end surface of the head 10 of the butt 9 on an extension line of the clamping groove 11, and the engagement groove 24 is formed on the lower rear surface of the center plate 2. An engaging protrusion 25 that fits into the groove 24 is protruded.

Therefore, in addition to the locking hole 3 and the locking piece 15, the locking protrusion 25 and the locking groove 24 also engage the core 2 and the butt 9, so that they are more firmly connected and fixed, and the core 2 Since the rear end surface is exposed perpendicularly across the center of the rear end surface of the bottom metal 9, the rear end surface of the bottom metal 9 is
It can be used as an accent to bring out a decorative effect.

Note that this invention is not limited to the above-mentioned embodiments; instead, the insertion part 14 protruding from the head 10 of the butt 9 is not provided, only the head 10 is fitted into the handle 4, and the core 2 and In order to connect the handle 4 to the center plate 2 with a caulking pin more firmly than by caulking, or to hook the knife on a hook on a hanger board, the hook is attached to the rear end surface of the butt plate 9. Any changes may be made without departing from the spirit of the invention, such as by providing an engaging protrusion with an engaging hole.

As detailed above, this invention consists of a knife body with a locking hole transparent at the rear end of the core, and an insertion groove in the longitudinal direction of one side of the knife body into which the core is inserted. A fitting groove is formed into which the rear end of the handle fits into the base of the handle and the base end of the handle to the knife body, and into which the rear end of the core is inserted; In addition, the locking plate has a protruding locking piece that engages with the locking hole on one side of the locking groove, so that the locking plate can be firmly fixed to the handle and can be used for a long time. However, it does not come off, and can be assembled with one touch, and has excellent practical effects as a structure for attaching the core and handle of cooking utensils.
