Description

[Detailed description of the invention] The present invention relates to a structure for assembling the core and handle of cooking utensils, etc., and its purpose is to facilitate the assembly of the core and handle, and also to create a boundary between the body and the core using the base. To provide a structure for assembling a core and a handle in a cooking utensil, etc., in which the intervening part is reinforced to make it durable, and the number of parts of the mouthpiece is reduced, making it easy to handle. .

The following is an example of the embodiment of the present invention.
Referring to Figure 4, 1 is the butterfly's body, and 2 is a core integrally formed at the rear end, which extends long toward the rear.

Reference numeral 3 denotes four parts formed over almost the entire lower side of the core 2, which are gently curved upward.

Reference numeral 4 denotes a handle attached to the core 2, and the core 2 is inserted into a mounting groove 5 formed over the entire front and rear direction leaving only the lower part of the handle. It is crimped in 6 places.

The bottom surface of the mounting groove 5 of the handle 4 extends linearly in the front-rear direction, so when the core 2 is assembled to the handle 4, there is a slight gap between the bottom surface of the mounting groove 5 and the recess 3 of the core 2. A gap 7 is formed.

As shown in FIG. 3, reference numeral 8 is a mounting recess with a wide width (width in the thickness direction of the handle) formed at the front end of the mounting groove 5 of the handle 4, and is open forward and upward.

As shown in FIG. 3, the mounting recess 8 has a triangular shape from the front and a gently curved concave surface 9 at the bottom.

10 is a cap attached to the front end of the core 2; 12 is a cap attached to the front end of the core 2;
As shown in the figure, there are a pair of left and right cap pieces constituting the cap body 11, which are located on both left and right sides of the front end of the core 2 and on the body 1.
It abuts on both the left and right sides of the rear end, and these parts are glued.

Reference numeral 13 denotes a connecting portion that connects the two cap pieces 12 at their lower portions, and is formed integrally with the two cap pieces 12 .

The lower half of the cap body 11 is a guard portion 14 that protrudes downward and reaches the lower edge of the body 1 of the butterfly.

In particular, reference numeral 15 denotes a pair of left and right mounting pieces which are integrally provided on the upper rear surface of each cap piece 12 and project as shown in FIG. I'm starting to get it.

The core 2 is bonded between both mounting pieces 15.

Both mounting pieces 15 are plate-shaped and fit into the mounting recess 8 of the handle 4.
Similarly, the front surface has a roughly triangular shape, and the slanted rear surface 16 extends in a straight line.

Further, both mounting pieces 15 are caulked 17 to the core 2 at the upper front portion thereof.

Note that both cap pieces 12 and mounting pieces 15 of the cap 10 are attached to the core 2.
On the other hand, the adhesive may be fixed in advance prior to caulking.

When the mounting piece 15 of the cap 10 is inserted into the mounting recess 8 of the handle 4, the concave surface 9 of the mounting recess 8 and the rear surface 1 of the mounting piece 15
6, a gap 18 is formed between the two.

As shown in FIG. 4, the caulking hole 19 of the mounting piece 15 has a large diameter portion 20 at its outer end, and when the cap 10 is caulked to the core 2, both ends 22 of the caulking pin 21 are completely buried. It is now possible to do so.

In order to assemble the handle to the core of the fan constructed as described above, the base 10 is first attached to the front end of the core 2.

In this case, the crimping pin 21 is inserted into the caulking hole 19 on the pair of attachment pieces 15 of the cap 10 to caulk the core 2 and the cap 10 together.

When caulking, both ends 22 of the caulking pin 21 are buried in the large diameter portions 20 of the caulking holes 19 of both attachment pieces 15 so as not to protrude outward from the attachment pieces 15.

When the cap 10 is attached to the core 2 in this manner, both cap pieces 12 of the cap 10 come into contact with both sides of the front end of the core and both sides of the rear end of the body 1, thereby adhering these parts.

After the cap 10 is fixed to the core 2, both of them are then assembled to the handle 4.

In this case, insert the mounting piece 15 of the base 10 into the mounting recess 8 at the front end of the handle 4, and with the core 2 inserted into the mounting groove 5 of the handle 4, fasten the core 2 to the handle 4 at three places. Finished 6th.

At this time, the attachment piece 15 of the cap 10 is also caulked at the caulking section 6 at the front end of the core 2 at the same time.

This 2. When the core 2 and the cap 10 are assembled to the handle 4 in this manner, there is a space between the recess 3 on the lower side of the core 2 and the bottom surface of the mounting groove 5 of the handle 4 over almost the entire length of the handle 4. A gap 7 is formed.

Further, a gap 18 is also formed between the rear surface 16 of the mounting piece 15 of the base 10 and the mounting recess 8 concave surface 9 of the handle 4.

Therefore, when the cap 10 and the core 2 are inserted into the handle 4, there are no chips remaining in the mounting recess 8 or the mounting groove 5 of the handle 4, or chips on the inner wall of the handle 4 that have been scraped off by the cap 10 and the core 2 during insertion. Scraps, etc. should be removed from each gap 7 and 1 mentioned above.
8, so the shavings, etc. accumulate in the core 2 and the countryside 10.
will not be pushed forward or upward from the handle 4.

Therefore, the rear end of the core 2 may float up from the bottom surface of the mounting groove 5 of the handle 4, a gap may be created between the rear end of the cap body 11 and the front end surface of the handle 4, or even the rear end of the mounting piece 15 of the cap 10 may This can prevent gaps from forming between the two.

In the above-mentioned flywheel, since it is only necessary to attach the base 10 to the core 2 and swage both of them onto the handle 4, the assembly can be facilitated.

Further, since the main body 11 and the mounting piece 15 of the base 10 are integrally formed, the whole body is strong and easy to handle, making it even easier to assemble the core 2 and the handle 4. .

Furthermore, as mentioned above, by attaching the cap 10 to the core 2 that clamps these parts from the front end of the core 2 to the rear end of the body 1, the current part of the core 2 and body 1 of the houcho is This part can be strengthened and made durable.

That is, when the cap 10 is not attached, when a force is applied to the body 1 in the lateral direction (in the direction of the thickness of the body), the core 2 protrudes from the front end of the handle 4 at the narrow part (where the core and body (current part) may be bent, but the above-mentioned cap 1
0, the boundary between the core 2 and body 1 is completely clamped by the cap 10, so that such breakage of the core 2 can be prevented.

As shown in FIG. 5, the base 10 in the above embodiment may be formed by making the length of the mounting piece 15 slightly longer so that its rear end extends vertically straight instead of obliquely, or as shown in FIG. The attachment piece 15 can also be formed long enough to reach the rear end of the handle 4.

When the attachment piece 15 reaches the rear end of the handle 4, the handle 4 may be a split handle or a handle connected at the lower end similar to that of FIG.

Further, both cap pieces 12 of the cap 10 may be integrally connected at their upper ends by connecting portions 13 as shown in FIG. 7, and furthermore, as shown in FIG.
5 lower the top surface between the base body 11 and the step 23,
Correspondingly, the upper surface of the mounting recess 8 of the handle 4 is closed 24.
When the cap 10 is assembled to the handle 4, the mounting piece 15 of the cap 10 may not be exposed to the back side of the handle 4.

In order to prevent relative displacement in the front-rear direction between the core 2 and the cap 10, a locking recess 25 is formed in the front end of the back side of the core 2, as shown in FIG. The main body 11 is connected at the upper part (back side) by the connecting part 13, and the back side position of both mounting pieces 15 is aligned with the back side position of the cap main body 11, and the vertical width is the same as the top and bottom of the core 2. Match width.

The assembly of the core 2 and the cap 10 is sometimes carried out using the cap body 11.
The connecting portion 13 is engaged with the locking recess 25 of the core 2.

In this way, the cap 10 and the core 2 will not shift back and forth relative to each other.

It should be noted that an ordinary ring-shaped or cap-shaped cap may be further mounted on the cap body 11 of the above embodiment.

The present invention can also be embodied in the assembly of cores and handles of not only the above-mentioned knives, but also Western tableware, mountain climbing knives, chitin soles, saws, machetes, fruit knives, etc.

In the embodiment described above, the cap pieces 12 are connected at their upper ends (FIG. 7) or lower ends (FIG. 2), but these two embodiments can be combined to connect the cap pieces 12 at both their upper and lower ends. .

As described in detail above, the present invention involves a pair of cap pieces being brought into contact with both the left and right sides of the core formed integrally with the body, from the front end to the rear end of the body, and sandwiching this part.
Both cap pieces are connected by a connecting part formed integrally with them, and a pair of mounting pieces are provided integrally with the cap pieces on the rear surfaces of both cap pieces and are brought into contact with both sides of the core, With the rear surfaces of both cap pieces in contact with the front end surface of the handle and both mounting pieces inserted into the mounting grooves of the nozzle, both mounting pieces are fixed to the handle together with the core, so that the core and the handle are separated. This has the effect of making assembly easier, reinforcing the boundary between the body and the core with the cap to make it stronger, and reducing the number of parts in the cap, making it easier to handle. This is a preferred design for industrial use as a structure for assembling the core and handle of cooking utensils, etc.
