Description

[Detailed description of the invention] The present invention relates to an assembly structure between a core and a handle for cooking utensils, eating utensils, etc., and its purpose is to provide an assembly structure that allows both of these to be easily and firmly assembled. There is a particular thing.

An embodiment of the present invention embodied in a butterfly will be described below with reference to the drawings. 1 is the body of the butterfly, 2 is a core integrally formed on the rear end, and extends to the rear end of the handle 16 described later. ing.

This core 2 contains a yakiki.

Reference numeral 3 denotes a horizontally long mounting hole punched out at the front end of the core 2, which is drilled before the core 2 is hardened.

Reference numeral 4 denotes a substantially rectangular rotation groove formed in the rear half of the mounting hole 3, and a pair of arcuate upper and lower recesses 5 are formed on both upper and lower inner edges of the rear end.

Reference numeral 6 denotes a relatively long insertion groove formed in the front half of the mounting hole 3, and its vertical width A is narrower than the vertical width B of the rotation groove 4.

Reference numeral 7 denotes a pair of upper and lower tapered portions formed at the boundary between the rotation groove portion 4 and the insertion groove portion 6, and the front end portions extend obliquely toward each other.

Reference numeral 8 denotes a pair of upper and lower notches formed on both the upper and lower inner side edges of the front end of the insertion groove 6, which are caused by stress concentration when a force is applied to the insertion groove 6 to expand it in the vertical direction. This is to prevent both front end corners from cracking.

Reference numeral 9 denotes a cap attached to the front end of the core 2, which is die-cast and is attached to both sides of the core 2 at a position corresponding to the mounting hole 3 of the core 2, as shown in Fig. 1.3.4. A square plate having the same thickness as the core 2 that is inserted into the front end of the insertion groove 6 of the mounting hole 3 of the core 2, which integrally connects the pair of cap pieces 10 that come into contact with the base pieces 10 and the both cap pieces 10. It consists of a connecting piece 11 having a shape.

In addition, the front-to-back width of the connecting piece 11 is the front-to-back width B of each cap piece 10.
1, and the front and rear surfaces of the connecting piece 11 are slightly retracted from the front side of the cap piece 10.

The longitudinal width B1 and height C1 of each cap piece 10 are the same as or slightly smaller than the vertical width B and longitudinal width C of the rotation groove 4 of the attachment hole 3 of the core 2, respectively.

Further, the height A1 of the connecting piece 11 matches the vertical width A of the insertion groove 6 of the mounting hole 3.

Furthermore, the connecting piece 11 is rotatable within the rotation groove 4 of the attachment hole 3.

Reference numeral 12 denotes an intervening member fitted immovably into the mounting hole 3 at the rear of the cap 9, and is made of a single iron plate that is not tempered and therefore easier to drill than the core 2. There is.

The intervening member 12 has the same plate thickness as the core 2, and in particular, as shown in FIG. Both concave portions 5 of dynamic groove portion 4
It consists of a pair of protrusions 14 that are engaged inside and a narrow part 15 that continues to the front end of the wide part 13.

16 is a caulking pin 1 against the core 2 at the rear of the cap 9.
The handle is made of plastic and is caulked in two places at the front and back by 7, and consists of a pair of handle pieces 18 connected to each other at the lower rear half as shown in FIGS. 3 and 5.

The front end surface of each handle piece 18 is in contact with the rear end surface of each base piece 10.

In addition, a pair of caulking holes 1 are drilled in the core 2 for caulking.
Of 9a and 19b, the front part is a round hole drilled in the wide part 13 of the intervening member 12, and the rear part is a long hole extending in the front-rear direction at the rear end of the core 2. is doing.

The front caulking hole 19a is drilled together with the caulking hole 20a of both handle pieces 18 before the handle 16 is caulked, and the rear caulking hole 19b is completely separate from the caulking hole 20b of the handle piece 18 in the core 2. It can be opened in advance before hardening.

Once upon a time, in a flywheel constructed as described above, the core 2
To assemble the handle 16, first attach the base 9 to the core 2.
Attach to.

When assembling the cap 9, place it sideways as shown in Figure 2, and insert one cap piece 1 from one side of the core 2.
0 into the rotation groove 4 of the mounting hole 3, and the connecting piece 11 is positioned within the rotation groove 4.

Then, in this state, the cap 9 is rotated 90 degrees to the right or left so that the front part thereof faces forward, and is stood vertically.

In this case, the connecting pieces 11 are rotated within the rotation groove 4, and the inner surfaces of each cap piece 10 are brought into close contact with both side surfaces of the core 2.

After the cap 9 is erected, move it to the front end of the insertion groove 6 of the mounting hole 3.

At this time, since the tapered part 7 is formed at the boundary between the rotation groove part 4 and the insertion groove part 6, the connecting piece 11 of the cap 9 is smoothly moved into the insertion groove part 6.

In the moved state, both upper and lower ends of the connecting piece 11 are in the insertion groove 6.
Since the cap 9 is tightly fitted to both the upper and lower inner edges of the core 2, the cap 9 will not wobble vertically with respect to the core 2.

Note that an adhesive may sometimes be used for attaching the cap 9 in this way.

After the cap 9 is attached, the interposed member 12 is inserted into the attachment hole 3 behind it.

In this state, the intervening member 12 cannot move back and forth or up and down within the mounting hole 3, and thus the cap 9 also becomes unable to move back and forth.

After the cap 9 and the intervening member 12 are attached in this manner, the handle 16 is finally crimped onto the core 2 with the crimping pin 17 so that the pair of handle pieces 18 are brought into contact with both sides of the core 2.

In this case, the intervening member 12 of the core 2 and the intervening member 12 of the core 2 are temporarily fastened by using the caulking holes 20b and 19b pre-drilled in the rear end of the handle 16 and the rear end of the core 2. The intervening member 12 and the handle 16 in corresponding positions
Holes 19a and 20a are bored in the front end.

After this, the handle 16 and the core 2 are caulked with the pin 17.
Caulk with.

Since the intervening member 12 that is to be drilled together does not have a hardening hole, the caulking hole 19a can be easily drilled.

When temporarily fastening the handle 16 and the core 2, the long and large caulking hole 19b of the core 2 is used to move both 16, 2 back and forth relative to each other, so that the rear end positions of both 16.2 are accurately adjusted. Arrange.

If the handle 16 is attached, the attachment hole 3 of the core 2 will be covered by the handle 16, so the attachment hole 3 will be covered by the handle 16.
Not exposed to the outside.

Further, since the mounting hole 3 is filled with the intervening member 12, it does not become a space, and therefore, water does not accumulate there, and the handle 16 is not corroded by this water.

Furthermore, by fitting the intervening member 12 into the mounting hole 3 in this way, even if the core 2 breaks at the rear end of the mounting hole 3 and splits into two parts, the intervening member 12 can be inserted into the mounting hole 3. Since the pair of protrusions 14 of the member 12 are locked in the pair of recesses 5 of the mounting hole 3, this intervening member 12 prevents the front part of the broken core 2 from shifting forward from the handle 16. disappears.

Also, when the handle 16 and the core 2 are assembled as described above, the swage holes 19a of both 16 and 2 are closed.

Since the positions of 19b, 20a, and 20b can be matched accurately, these can be assembled accurately and easily.

In addition, in the assembled state, the front part of the handle 16 is attached to the core 2 by the front caulking pin 17 through the intervening member 12 so that it cannot move back and forth, so the rear caulking hole 1 of the core 2
Even if 9b is an elongated hole, when assembling the rear handle 16 is the core 2.
There is no deviation back or forth.

If the cap 9 is assembled as described above, the cap 9 only needs to be inserted into the mounting hole 3 of the core 2 and then rotated 90 degrees and moved into the insertion groove 6, so this assembly is easy. It becomes easy.

In addition, the cap 9 is solid because it is integrally hollowed out, and when it is assembled to the core 2, there is a handle 16 at the rear end.
Since the front ends of the interposed member 12 are in contact with each other, there is no possibility that the interposed member 12 will shift rearward.

In particular, if the connecting piece 11 is formed into a square plate shape as described above, when the cap 9 is assembled to the core 2, the upper and lower ends of the connecting piece 11 will be tightly fitted into the upper and lower inner edges of the insertion groove 6. The cap 9 will no longer shake against the core 2.

When the connecting piece 11 of the cap 9 is tightly fitted into the insertion groove 6,
Although a force acts on the insertion groove 6 to expand it upward and downward, the core 2 does not break at the front end of the insertion groove 6 due to this force.

That is, since a pair of notches 8 are formed at the front end of the insertion groove 6 to avoid stress concentration, the core 2 will not be cracked by the force of expanding the insertion groove 6. be.

Note that the pair of notches 8 are inserted into the insertion groove 6 as shown in FIG.
It may be formed so as to protrude forward from the front end corner.

In addition, in this embodiment, the insertion groove 6 of the attachment hole 3 of the core 2 is formed narrow, so that the base end of the core 2 is weak against lateral forces (in the thickness direction of the core 2). It won't happen.

Therefore, even if force is applied to the body 1 from the side while the fly is in use, the core 2 will not break at its base end.

Therefore, it is possible to reduce the degree of tempering in this portion or to omit tempering altogether.

Note that the width of the rotation groove 4 of the mounting hole 3 is larger than the width of the insertion groove 6 and is slightly weaker in terms of strength, but this portion is sandwiched between the pair of handle pieces 18, and the core Since a relatively long insertion groove 6 is provided between the base end of the core 2 and the distance from the base end of the core 2 is long, even if a lateral force is applied to the body 1, the core There is no possibility that the base end of 2 will break.

Note that the connecting piece 11 may be formed into a disk shape having the same diameter as the vertical width A of the insertion groove 6 of the mounting hole 3.

The handle 16 of the embodiment described above may be split into pieces instead of being integrated, and the core 2 may be shaped to extend to the rear end of the handle 16 with the same width.

When the handle 16 is split into chives, it can also be made of wood.

In addition to the die-cast bottom mold described above, the base 9 can also be made of cast metal or plastic;
As shown in FIG.
A locking recess 22 into which a part of the front end of the core 2 can be inserted may be formed.The mounting hole 3 of the core 2 and the base 9 in the above embodiment are connected to the core 2 as shown in FIG. In this case, the cap 9 can function as the butt cap 19.

Also, as shown in FIG. 9, insert the insertion groove 6 of the mounting hole 3 into the core 2.
If the pivot groove 4 is provided in the center of the base so that it extends long in the front-rear direction, the base 9 and the butt 19 will fit into the mounting hole 3 from the pivot groove 4 and be moved back and forth. By doing so, it can be easily assembled to the core 2.

In addition, in this case, since each insertion groove 6 of the mounting hole 3 can be used as a long groove-shaped caulking hole 19b, the caulking hole 1 of the intervening member 12 fitted into the rotation groove 4 can be
Drill only the hole 9a along with the caulking hole of the handle 16.

Note that in this embodiment, the taper portion 7 and notch 8 in the mounting hole 3 are omitted.

In the present invention, it is not necessarily necessary to attach the cap 9 and the bottom cap 19 to the core 2, and if these are omitted, the 10th
As shown in the figure, the attachment hole 3 of the core 2 and the intervening member 12 may have a simple square shape.

Note that the mounting hole 3 and the intervening member 12 can also be changed to other shapes such as a circular shape.

Furthermore, the inner edge of the mounting hole 3 and the outer edge of the intervening member 12 are
As shown in FIG. 1, the core 2 may have an oblique shape so as to be inclined in the thickness direction of the core 2.

If it is formed in an oblique shape, when the interposed member 12 is inserted into the mounting hole 3 from the side, the interposed member 12 will not fall out to the opposite side.

Furthermore, as shown in FIG. 12, the mounting hole 3 and the intervening member 1
2 into a rectangular shape extending in the front-rear direction of the core 2, and a pair of caulking holes 19a, 19b are both inserted into the intervening member 12.
It may be formed as follows.

Alternatively, as shown in FIG. 13a, the core 2 may be formed into a half-core with the mounting holes 3 opening toward the rear end of the core 2.

Furthermore, as shown in FIGS. 13(c), the attachment hole 3 is opened to the rear end of the core 2, and the engagement protrusion 25 is formed inside this opening, while the intervening member 12 in the attachment hole 3 is opened to the rear end of the core 2. Engagement recesses 26 that engage with the engagement protrusions 25 may be formed on both upper and lower sides.

When the engaging protrusion 25 and the engaging recess 26 are formed, the core 2 will not shift back and forth with respect to the interposed member 12, so the front end of the interposed member 12 is not necessarily aligned with the front end of the mounting hole 3. Since there is no need for the interposed member 12 to come into contact with the interposed member 12, the length of the interposed member 12 can be shortened and the material used therefor can be saved.

The intervening member 12 may be made of a material that is easier to drill than the core 2, so it may be made of plastic instead of metal.If it is made in this way, it will not rust and will not fit inside the mounting hole 3. The effect of preventing corrosion of the handle 16 can be further ensured by filling the space of the handle 16.

When plastic acid is used, as shown in FIG. 14, a recess 23 is formed on the outer periphery of the intervening member 12, and a protrusion 24 is formed on the inner periphery of the mounting hole 3. 24
and the recess 23 are fitted into each other to fit the interposed member 1.
2 can be firmly assembled to the core 2.

Further, the thickness of the intervening member 12 may be made thicker or thinner than that of the core 2 (see FIG. 15).

In addition, if it is necessary to make a caulking hole 19a smaller in diameter than the thickness of the thick core 2, insert the thin intervening member 12 with the small caulking hole 19a into the core. It is only necessary to fit it into the mounting hole 3 of No. 2.

The present invention can also be embodied in an assembly structure for items such as a kitchen knife, a Western tableware, a climbing knife, a kitchen tool, a saw, a machete, a fruit knife, a bottle opener, a can opener, etc.

As described in detail above, the present invention immovably fits the intervening member 12 made of a material that is easier to drill than the core 2 into the mounting hole 3 of the core 2, and By forming the caulking hole 19a and caulking the handle 16 to the core 2 using the caulking hole 19a, the handle can be easily and securely assembled to the core, making it a cooking utensil. This is an excellent practical idea for the assembly structure of the core and handle in etc.
