DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing an engaging body, and more specifically, a structure for inserting, inserting, engaging and fixing an inserting body in an engaging body having a relationship between an inserting body and an inserted body. About technology.

[0002]

2. Description of the Related Art Conventionally, in a fixing structure having a relationship between an inserted body and an inserted body, a convex portion is formed on the inserted body and a concave portion is formed on the inserted body in order to secure the fixing. In many cases, a fixed structure such as engaging the unevenness is employed. In the case where an adhesive is used, such irregularities may not be provided in some cases. However, if the irregularities are provided and the adhesive is used in the engagement portion of the irregularities, it becomes more reliable.

On the other hand, as a technique related to the present invention,
PCT JP94 / 00351 (International Publication Number; WO
No. 94/20280), the technology of “cellulose-based fine particles, wood-like molded articles and wood-like products” will be briefly described. The ground powder obtained by pulverizing the cellulose material as a raw material is subjected to a grinding treatment to obtain a powder particle having an increased bulk specific gravity, and a surface particle having a smaller diameter and harder than the powder particle is fixed to the outer peripheral surface of the powder particle. The fixed particles are mixed with a resin and a pigment and melted, and thereafter or simultaneously with the melting, formed into a desired shape by extrusion molding or injection molding. Then
It is possible to provide a method for producing a wood-like product and a wood-like product having a pattern very close to the grain of a natural tree on the surface and having a feeling such as a touch feeling similar to that of a natural tree.

[0004]

However, the above technique has the following problems. That is, if the shape is formed such that the insert and the insert are engaged with each other and fixed, the engagement portions fight each other,
The insertion work for engagement is very time-consuming, and in some cases, the projection for insertion or the recess to be inserted may be damaged.

[0005] In particular, in the case of woody products formed by the technique disclosed in the PCT application, the above-mentioned situation has been prominent. Further, after the meshing and fixing, there is a case where the boundary between the inserted body and the inserted body varies due to an error in one or both of the molding dimensions, an operation error during the fixing, and the like.

The problem to be solved by the present invention is to provide a fixing structure for facilitating an insertion work for engagement in a structure for engaging and fixing an inserted body and an inserted body and preventing a situation such as breakage from occurring. Is to do. Claim 1
SUMMARY OF THE INVENTION An object of the present invention is to provide a fixing structure for facilitating insertion work for engagement in a structure for engaging and fixing an inserted body and an inserted body and preventing a situation such as breakage.

It is still another object of the present invention to provide a fixing structure that makes inconspicuous variations in the boundary between the inserted body and the inserted body that occur after engagement and fixing.
The object of the invention described in claim 3 is to apply the object of the invention described in claim 1 and claim 2 to the technology of “woody molded article” described in PCT JP94 / 00351.

[0008]

SUMMARY OF THE INVENTION The present invention is to achieve the above object. The invention described in claim 1 is a fixing structure for engaging and fixing by inserting the convex portion (B) of the insert (A) into the concave portion (D) of the insert (C), ) And the insert (C) are recesses of the insert (C).
Part or all of the peripheral surface in the insertion direction of (D) is provided with a corrugated engaging portion (E) of equal pitch, and the convex portion (B) of the insert (A) includes:
A wavy engaging portion that engages with the engaging portion (E) of the inserted body (C), and the engaging portion of either the inserted body (A) or the inserted body (C) is provided.
The pitch of (EorF) is a multiple of the pitch of the engaging portion (EorF) of the inserted body (A) or the inserted body (C).

For example, the pitch of the engaging portion (E) of the insert (A) is set to one half of the pitch of the engaging portion (EorF) of the inserted object (C). Next, the operation of the invention will be described. A case in which the projection of the insert (A) is fixed by inserting the protrusion of the insert (A) into the recess of the insert (C) will be described. In this case, the protrusion (B) of the insert (A) is opposed to the engagement portion of the insert (C).
And insert the convex part (B) of the insert (A) into the concave part (D) of the inserted body so that the engaging portions (E, F) are engaged with each other. Then, the insert (A) is inserted while the engaging portion (EorF) having a large pitch partially cuts the engaging portion (ForE) having a small pitch. Therefore, breakage is unlikely to occur. When the engaging portion (F) of the concave portion (B) of the inserted body (A) stops, the engaging portion (E) of the inserted body (C) is engaged, and the fixing is completed at this portion. I do.

In this connection, if an adhesive is applied to one or both of the engaging portions (E, F), a stronger fixing can be performed. The invention according to claim 2 is
The engaging body fixing structure according to claim 1 is technically limited, and at a boundary (G) between the inserting body (A) and the receiving body (C), the inserting body (A) and the receiving body (C) Either or both
This is a fixing structure for an engaging body, characterized in that it has a notched portion (H) that is cut out so that the section along the boundary (G) has the same cross-sectional shape perpendicular to the direction of the boundary (G).

Next, the operation of the invention according to claim 2 will be described. When the fixing of the inserted body (A) and the inserted body (C) is completed, the boundary (G) may be slightly different from the assumed boundary, but slightly larger.
However, even in this case, the portion along the boundary (G) is provided with a notch (H) formed so that the cross-sectional shape perpendicular to the boundary (G) direction is the same. From the beginning, the portion looks like a groove, and the variation of the boundary portion becomes a problem of the width of the groove, so that the appearance can be made not so noticeable.

According to a third aspect of the present invention, the engaging body fixing structure of the first or second aspect is technically limited. That is, one or both of the inserted body and the inserted body are made of a resin obtained by mixing a powder prepared by supporting a hard fine powder with a smaller diameter than the fine powder on the surface of the fine powder of the cellulosic material. It is characterized in that it is formed so as to exhibit a wood grain pattern by being colored and molded.

Here, the term "cellulosic material" includes, in addition to natural wood, sawdust, rice straw, bacas and the like. The “resin” includes a hard resin and a soft resin, and examples thereof include a vinyl chloride resin, a foamed vinyl chloride resin, a polyethylene resin, a polypropylene resin, a phenol resin, a urethane resin, a polyurethane resin, an ABS resin, and a polystyrene resin. "Fine powder" is a metal material such as titanium oxide, ferrite, aluminum, nickel, and silver, or a nonmetallic material such as ceramic and calcium carbonate.

The proportion of the powder mixed with the resin is 30% by weight.
Is not exceeded. This is because the fluidity at the time of molding deteriorates, and there is a problem in molding. The material that “colors the resin” is a colored pigment, for example, an inorganic pigment such as iron oxide, cadmium yellow, or carbon black. The structure for fixing the engagement body according to the third aspect has the following operation.

First, a cellulosic material is pulverized to obtain a pulverized powder. Next, the pulverized powder is subjected to a grinding treatment to increase the bulk specific gravity to obtain powder particles. Next, fix the surface grains to the powder,
"Powder" is obtained. This powder is mixed with a resin and colored to obtain a product material. The product material is melted and subsequently or simultaneously formed.

The molded article formed by the above-described method exhibits a wood grain pattern even if it has a complicated cross-sectional shape, and is suitable for use as a decorative part or the like inside a building. In other words, even a member having a cross-sectional shape that would be troublesome if natural wood is cut, it can be provided as a molded product exhibiting a grain pattern. The engaging body and / or the engaged body molded in this way have lower elasticity and are more likely to be damaged than those molded from ordinary resin alone.
Since the pitch of the engaging portion (EorF) of either (A) or the inserted body (C) is a multiple of the other pitch of the inserted body (A) or the inserted body (C), a large pitch The insert (A) is inserted while the joining portion (EorF) removes the engaging portion (ForE) having a small pitch halfway. Therefore, breakage is unlikely to occur.
