Description

[Detailed description of the invention] This invention relates to a caulking structure for the handle of a cooking utensil such as a knife.

Conventionally, in the handle of a cooking utensil that has been caulked to the core with a caulking pin, the outer surface of the caulking pin is exposed on the side surface of the handle, giving the handle a decorative effect.

In order to enhance this decorative effect, caulking pins with a chrysanthemum-like uneven pattern on the outer surface have been proposed, but such caulking pins require a polished finish to make the surface of the handle flush. Since the uneven pattern may be polished and disappear, there is a problem that the surface polishing cannot be completed completely, but rather deteriorates the appearance and lowers the commercial value.

This idea was created by focusing on the problems in the conventional technology mentioned above, and actively utilizes the caulking holes in the handles of cooking utensils to create a highly decorative and versatile caulking structure for the handles. The purpose is to provide.

Hereinafter, a first embodiment in which the caulking structure of the handle of the cooking utensil of this invention is embodied in the handle of a knife will be explained with reference to FIGS. 1 and 2. 1 is the body of the knife, and there are three A core 2 with through holes 2a for caulking is provided at certain locations.

Reference numeral 3 denotes a pair of wooden handle members that are caulked to both sides of the core 2 to form a handle, and the through hole 2a of the core 2
A caulking hole 3a is transparently provided at a position corresponding to .

Reference numeral 4 designates a male and female caulking pin which is inserted into the through hole 2a of the core 2 and the caulking hole 3a of the pair of handle members 3, and is used to clamp the core 2 between the pair of handle members 3. .

5 is a cylindrical fitting recess formed between the outer end surface of the caulking pin 4 and the outer surface of the handle member 3; 6 is the fitting recess 5;
It is a disc-shaped decorative piece that is fitted and bonded to seal the crimping pin 4 and hides the outer end surface of the caulking pin 4, and is made of colored laminated resin.

Now, to explain the operation of the first embodiment constructed as described above, first, in the embodiment, even if the surface of the handle is polished after the decorative piece 6 is fitted into the fitting recess 5 of the handle, the decorative piece will not be removed. 6 is made of colored resin, so it is a decorative piece 6.
The desired color will appear on the surface.

In addition, if the decorative piece 6 is made of laminated resin as in this embodiment and the decorative piece 6 is fitted and glued into the fitting recess 5 of the handle, the outer end surface of the caulking pin can be attached to the side surface of the handle member as in the conventional case. If the expansion rate of the handle member and the crimping pin is high, a gap will be created between the crimping hole of the handle member and the crimping pin, and fine dust, sewage, oil, etc. may enter the gap, causing the handle to become damaged. There is no need to worry about making the appearance look dirty.

The decorative piece 6 in this embodiment may be divided into two or three parts, each made of synthetic resin of a different color, or shaped into four or more parts, as shown in FIGS. 3a and 3b, or joined together. Then, as shown in Figure 4,
As the decorative piece 6, a cylindrical decorative tube 6a made of metal or resin may be fitted with a disk-shaped decorative plate 6b, or the decorative tube 6a may be stacked two or more times. It is also possible to use a cylindrical one.

Next, to explain the difference from the first embodiment in the second embodiment shown in FIG. It is shaped like a wide square, and its inner wall tapers outward.

The decorative piece 6 is shaped like a truncated quadrangular pyramid whose four sides are tapered outward in correspondence with the fitting recess 5.

Therefore, in this embodiment, since the fitting recess 5 is wider than the maximum diameter of the crimping hole 3a, crimping the crimping pin 4 is easy, and also the inner wall of the fitting recess 5 and the four sides of the decorative piece 6 Since it has a tapered shape that expands outward, the decorative piece 6 can be easily fitted into the fitting recess 5.

As detailed above, the caulking structure of the handle of the cooking utensil of this invention has a fitting recess for fitting a decorative piece at the outer end of the caulking hole provided through the handle, and By fitting the decorative pieces, the decorative effect at the caulking part of the handle is high, and the effect of providing a variety of patterns is achieved, so this is a practically preferable idea as a caulking structure for a handle in a cooking utensil.

Note that this invention is not limited to the above embodiments; for example, the material of the decorative piece may be the same as that of the handle member, or the material of the decorative piece may be selected from metal, bone, rubber, or glass. Any changes can be made without departing from the spirit of the invention, such as using a square plate whose west side is not tapered as a decorative piece.
