Description

[Detailed Description of the Invention] The present invention relates to a structure for assembling the handle of a kitchen knife with a base.

A wide variety of methods are used to assemble the handle of a knife with a nozzle, but it can basically be divided into two types: riveting and insertion. The riveted type is the first
As shown in the figure, the handle is placed on both sides of the core and rivets are used to fix it.In the insert type, the core is attached to the handle with a groove for inserting the core, as shown in Figure 2. This is a method of inserting the part and filling the gap with resin or the like and fixing it.

These methods require a large number of man-hours, such as co-processing the rivet holes and caulking the rivets, and also have problems with corrosion in the gaps between the core and the handle, between the rivet and the handle, or when resin is embedded. Since it takes a certain amount of time for the resin to harden, there are problems such as workability and the risk of detachment due to deterioration of the resin.

The present invention has been devised to avoid the above-mentioned problems.

That is, as shown in FIGS. 3 and 4, the core shaft of a knife material in which a blade, a mouthpiece with a positioning recess and a core shaft having a screw at the end are integrated is placed in the center. The through-hole of the handle has a through-hole into which the child shaft can be inserted, and a protrusion that can be fitted into the positioning recess of the base protrudes from one end, and a recess is bored at the other end. After inserting the knife, fitting the positioning recess of the cap and the protrusion of the handle, and tightening with a nut so that the end surface of the cap and the end surface of the handle are in contact with each other, and fixing the handle and the knife material, This invention proposes a structure for assembling the handle of a kitchen knife with a base, which is characterized in that the rear end of the handle is covered at the handle butt. In addition, the method of obtaining the knife material here is to prepare the three parts of the blade, the mouthpiece, and the core shaft separately and join them together by welding, or to combine the blade and the mouthpiece by welding. The cap and core shaft can be joined together by screwing, or as another method, a component can be prepared in which the cap and core shaft are integrated by the lost wax method, etc., and this can be joined to the blade by welding. Although there are methods for integrating, the present invention does not limit the acquisition method in any way.

As described above, the handle of the knife according to the present invention is secured by tightening with a nut, so it is easy to work, reduces man-hours, and can be easily replaced if the handle is damaged. Since the end of the handle is provided at the end of the handle, the product has features such as a sturdy appearance and a high-class image, and a product with high commercial value.
