Description

[Detailed Description of the Invention] (Object of the Invention) This invention mainly relates to the structure of a knife with a handle such as a kitchen knife and a petite knife. Further, the present invention particularly relates to a means for fixing the body to the handle of the cutting tool as described above. Furthermore, this invention is effective in reducing the production cost, especially when the body of the blade is made of a ceramic sintered body, by reducing the number of steps for assembling the blade and by reliably preventing the assembly failure. The objective is to provide such means.

 Conventionally, the body of a blade as described above has a handle portion that is narrower than the blade, and the handle portion is traditionally inserted into a wooden handle and fixed by mutual friction between the body and the handle. However, with the recent trend of Western kitchen knives, the fixing of the body to the handle of hard wood is often done by crimping two or three tacks. Therefore, the number of tacks applied to the handle of the body is reduced. Corresponding fastening holes are drilled. With the development of plastic production technology, tough synthetic materials such as various engineering plastics have been used instead of wood as the material for the handle, but the means of fixing the body to the handle has not changed.

 The caulking operation described above in the assembling process of the blade, which mainly fixes the body to the handle of the blade, requires a considerable skill. If the caulking is too loose, the blade will rattle, and if the caulking is too strong, the material of the handle will be damaged, and many unskilled workers will fail, which is an obstacle to mass production. In particular, when the body is a ceramic sintered body, the toughness is poorer than that of a metal body, so that defective products frequently occur due to the caulking work.

 This invention was made to address the above-mentioned drawbacks of the prior art in the production of cutlery.

 (Configuration of Device) The device will be described below with reference to the illustrated embodiment. First, with particular reference to FIGS. 7, 8 and 10, reference numeral 111 denotes a slot, which is formed in the longitudinal direction at the center of the width of the front wall 11 of the handle 1 formed of a hollow box.

 Referring now particularly to FIGS. 7 and 9, 151 is a semi-partition wall that projects inwardly from one side wall 15 of the handle. In order to manufacture such a hollow box handle, the left half part and the right half part cut along the center line DD of the box (see FIG. 9) are molded, and these are joined together and welded. Can be easily manufactured. Dotted lines drawn in FIGS. 6, 9, and 10 indicate the welding lines.

 Referring next to FIGS. 1, 8, 9 and 11, 31 and 32 are screw receiving cylinders and a half partition wall different from the half partition wall 151 described above, respectively. The cover 3 is inwardly extended, and the blind cover 3 is detachably fitted to the other side wall 16 of the handle. However, in the drawing, only the contour line of the fitting window hole 161 is visible.

 Next, with particular reference to FIGS. 2, 7, 9 and 11, reference numeral 4 denotes a screw penetrating the side wall 15 and screwed into the screw receiving tube 31. In FIGS. Is visible.

 According to the present invention, however, the width of the slot 111 and the length of at least the inner end of the slot 111 (see especially FIG. 10) are respectively the thickness t and the width w (FIG. 3) of the handle 21 of the body 2. , See FIG. 4).

 The outer diameter of the screw receiving cylinder 31 corresponds to the diameter of the fastening hole 22 formed in the handle 21 of the blade.

 The tip of the screw receiving cylinder 31 (see FIG. 9) projects inward beyond the center line DD of the handle 1.

 The distance d between the top wall 13 and the bottom wall 14 of the handle 1 (see FIG. 7) corresponds to the width w of the body handle 21 (see FIG. 4).

 Further, particularly referring to FIG. 9, the distance between the tip of the half partition wall 151 and the tip of the other half partition wall 32 corresponds to the thickness t of the body handle 21 (see FIG. 3).

 That is, the blade body fixing device according to the present invention has the groove hole 111, the half partition wall 151, the screw receiving cylinder 31 and the half partition wall 32, and the screw 4 as described above. At the same time, when the body handle 21 is inserted into the handle through the slot 111, the screw receiving cylinder 31 is inserted into the retaining hole 21, and the screw 4 is screwed, the handle 21 of the body is the handle. It will be understood that the top wall 13, the bottom wall 14, the screw receiving cylinder 31, the half partition wall 151, the half partition wall 32 and the slot 111 of the No. 1 are closely supported by the handle 1.

 To fix the body 2 of the blade to the handle 1 and assemble the blade, with the blind cover 3 and the screw 4 removed from the handle 1, insert the handle 21 of the body into the cavity of the handle 1 through the slot 111, Then, the blind cover 3 is fitted into the main body of the handle 1, and at the same time, the screw receiving cylinder 31 is inserted into the fastening hole 22 of the handle of the body, and the screw 4 inserted through the side wall 15 is screwed into the screw receiving cylinder 31. To do. This assembly work is extremely simple and can be done by even an inexperienced person without loss. Of course, since there is no caulking process as in the conventional assembly work, no expert is required, and even if the body 2 is a ceramic sintered body, there is no impact when caulking, so there is no crack on the body 2. There is no risk of damage.

 In this way, the assembly work of the blade is completed in an extremely short time. As for the assembled blade, the body 2 is fixed to the handle 1 as follows.

 That is, first, with particular reference to FIGS. 4, 7 and 8, the distance d between the top wall 13 and the bottom wall 14 of the handle corresponds to the width w of the handle portion 21 of the body, and Since the length of at least the inner end portion of the sloping slot 111 (see FIG. 10) corresponds to the width w of the handle 21, the back edge 24 and the abdominal edge 25 of the handle 21 are respectively the top wall 13 Since it closely contacts the bottom wall 14, the handle 21 of the body is fixedly supported in the vertical (up and down) direction in the cavity of the handle 1.

 Next, as described above, while the width of the slot 111 formed in the front wall 11 of the handle corresponds to the thickness t of the handle portion 21 of the body, it projects inward from one side wall 15 of the handle. The distance between the tip of the half partition wall 15 and the tip of another half partition wall 32 protruding from the inner surface of the blind lid 3 also corresponds to the thickness t of the handle 21 of the body, and at the same time the blind lid 3 is closed. Since it is screwed to the side wall 15 by the jig 4, both side surfaces of the body handle 21 in the handle cavity are tightly held by the front wall 11 of the handle and both side walls 15 and 16 of the handle so that the blade body 2 Is fixedly supported laterally (left and right).

 Further, as described above, the screw receiving cylinder 31 of the blind cover 3 penetrates the fastening hole 22 of the handle 21 of the body, and the outer diameter of the screw receiving barrel 31 corresponds to the diameter of the fastening hole 22. The body 2 is fixedly supported by the screw receiving cylinder 31 in the front-rear direction.

 In this way, according to the present invention, the body 2 of the blade is tightly fixed to the handle 1 in any of the up, down, left, right and front and rear directions, so that there is no rattling during use of the blade. Therefore, it is possible to enjoy work such as cooking with great security.

 As described above, the fixture for fixing the body of the cutting tool according to the present invention has the groove 111 formed in the front wall 11 of the handle and the semi-partition wall provided in one side wall 15 of the handle. 151, the screw receiving cylinder 31 and the half partition wall 32 provided on the flap lid 3, and the screw 4 screwed into the screw receiving cylinder 31 as described above. For the convenience of understanding the characteristics, the simplified example is shown. However, there are of course various variations in the shape, structure, or design of each part listed above.

 In the illustrated embodiment, with particular reference to FIGS. 7, 8 and 10, a step 112 is provided at the lower end of the front wall 11 of the handle 1 and the rear end of the notch 23 of the body 2 is The step portion 112 is brought into contact with the step portion 112. This is to match the position of the fastening hole 22 when the body handle 21 is inserted into the handle 1 with the position of the screw receiving cylinder 31 when the blind cover 3 is fitted into the window hole 161, in the assembly work of the blade. Therefore, the benefit is that the assembly work becomes easier.

 (Effect of the Invention) Thus, according to the present invention, the handle 1 of the body is inserted into the slot 111 provided on the front wall 11 of the handle 1 and the handle 1 is simply attached by screwing the blind lid 3. Since it is possible to completely fix the body to the machine, and because it does not involve the crimping work like the conventional assembly of a blade, not only the production of defective products is prevented, but even unskilled persons can quickly obtain excellent products. It is possible to produce, and therefore, the present invention greatly contributes to the efficiency of mass production of excellent blades and cost reduction. In addition, when fixing the body of the blade to the handle by means of caulking using tacks, it is customary to fix the tacks at least at a few places because there is concern about the reliability of the tacking. Although it was necessary to make a fastening hole in the body, it is also an advantage of the present invention that one fastening hole is sufficient according to the present invention. Further, according to the present invention, one of the advantages is that the body of various shapes can be freely exchanged for the purpose of cooking by unscrewing and screwing the screw 4.
