[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a structure for fixing an engaging body, and more specifically, has a structure for inserting an engaging body into an inserting body, engaging them with each other, and fixing them in an engaging body having a relationship of an inserting body and an inserted body. Regarding technology.

[0002]

2. Description of the Related Art Conventionally, in a fixing structure having a relationship between an insert body and an inserted body, in order to secure the fixation, a convex portion is formed on the insert body, and a concave portion is formed on the inserted body. In many cases, a fixed structure such as engaging the unevenness was adopted. When an adhesive is used, such unevenness may not be provided, but if the unevenness is provided and then the adhesive is used in the meshing portion of the unevenness, it becomes more reliable.

On the other hand, as a technique related to the present invention,
PCT JP94 / 00351 (International publication number; WO
The technology of "cellulosic fine particles, wood-like molded products and wood-like products" described in No. 94/20280) will be briefly described. The pulverized powder obtained by pulverizing the cellulose material as a raw material is ground to obtain powder particles having an increased bulk specific gravity, and fixed on the outer peripheral surface of the powder particles, surface particles having a smaller diameter and a hardness smaller than the powder particles. Fixed particles are obtained by mixing the resin and the pigment with the fixed particles, melting the fixed particles, and thereafter or simultaneously with melting, forming 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 which have a pattern extremely similar to the grain of a natural tree on the surface and have a texture such as a touch feeling similar to that of a natural tree.

[0004]

However, the above technique has the following problems. That is, when a shape is formed in which the insert body and the inserted body are engaged and fixed to each other, the engaging parts fight each other,
The insertion work for meshing is very time-consuming, and in some cases, the projection for insertion or the recess for insertion is damaged.

In particular, in the wood-like product molded by the technique described in the PCT application, the above-mentioned situation has remarkably appeared. Further, after the engagement and fixation, there is a case where variations occur at the boundary between the insert body and the inserted body due to an error in molding dimension of one or both of them, a work error during fixation and the like.

The problem to be solved by the present invention is to provide a fixing structure for facilitating insertion work for engaging in a structure for engaging and fixing an insert body and an inserted body and preventing a situation such as damage. To do. Claim 1
An object of the described invention is to provide a fixing structure for facilitating an inserting operation for engaging in a structure for engaging and fixing an insert body and an inserted body and preventing a situation such as damage.

It is another object of the present invention to provide a fixing structure that makes the variation in the boundary between the insert body and the inserted body, which is caused after the engagement and fixation, inconspicuous.
The object of the invention described in claim 3 is to apply the object of the invention described in claims 1 and 2 to the technique of "wood-like 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 body (A) into the concave portion (D) of the inserted body (C), ) And the body to be inserted (C) are the concave parts of the body to be inserted (C)
Part or all of the peripheral surface in the insertion direction of (D) is provided with a wavy engaging portion (E) of equal pitch, the convex portion (B) of the insert (A),
Equipped with a wavy engaging portion that engages with the engaging portion (E) of the inserted body (C), either the inserting body (A) or the inserted body (C)
The pitch of (EorF) is a multiple of the pitch of the engaging portion (EorF) of the insert body (A) or the inserted body (C), which is a fixing structure for the engagement body.

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 body (C). Next, the operation of the invention according to claim 1 will be described. A case will be described in which the convex portion of the insert body (A) is fixed by inserting it into the concave portion of the inserted body (C). In this case, the convex portion (B) of the insert body (A) with respect to the engaging portion of the inserted body (C)
Are brought closer to each other for insertion, and the convex portion (B) of the insert body (A) is inserted into the concave portion (D) of the inserted body so that the engaging portions (E, F) are engaged with each other. Then, the insertion body (A) is inserted while the engagement portion (EorF) having a large pitch scrapes off the engagement portion (ForE) having a small pitch halfway. Therefore, breakage is unlikely to occur. Then, when the engaging part (F) of the concave part (B) of the insert body (A) is stopped, the engaging part (E) of the inserted body (C) is engaged, and the fixing is completed at this part. To do.

In addition, at the time of this engagement, if one or both of the engaging portions (E, F) is coated with an adhesive, a more rigid fixing can be achieved. The invention according to claim 2 is
The engaging body fixing structure according to claim 1 is technically limited, and the insert (A) and the insert (C) are provided at a boundary (G) between the insert (A) and the insert (C). Either or both
The engaging body fixing structure is characterized by including a cutout portion (H) in which a portion along the boundary (G) is cut out so that the sectional shape perpendicular to the boundary (G) direction is the same.

Next, the operation of the invention described in claim 2 will be described. When the fixing of the insert body (A) and the inserted body (C) is completed, the boundary (G) may not be the boundary just as expected, but the boundary may be slightly wide.
However, even in that case, since the portion along the boundary (G) is provided with the absent portion (H) formed so that the sectional shape perpendicular to the boundary (G) direction is the same, From the beginning, that portion looks like a groove, and the variation in the boundary portion causes a problem of wideness of the groove, so that an appearance that is not so noticeable can be obtained.

The invention according to claim 3 is a technical limitation of the engaging body fixing structure according to claim 1 or 2. That is, one or both of the insert body and the inserted body is a resin obtained by mixing powder prepared by supporting a fine powder having a smaller diameter than the fine powder on the surface of the fine powder of the cellulosic material and hard. It is characterized in that it is formed to have a wood grain pattern by being colored and molded.

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

The ratio of the powder mixed with the resin is 30% by weight.
I try not to exceed. This is because the fluidity at the time of molding deteriorates, which hinders 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 fixing structure of the engaging body according to the third aspect has the following operation.

First, the cellulosic material is pulverized to obtain pulverized powder. Next, the crushed powder is ground to increase the bulk specific gravity and obtain powder particles. Next, fix the surface grains to the powder grains,
Obtain "powder". This powder is mixed with a resin and colored to obtain a product material. The product material is melted and shaped after or at the same time as it is melted.

The molded product molded by the above-mentioned method has a wood grain pattern even if it has a complicated cross-sectional shape, and is therefore suitable for use as a decorative component inside a building. In other words, even a member having a cross-sectional shape that would be time-consuming to cut natural wood can be provided as a molded product having a wood grain pattern. The engaging body and / or the engaged body molded in this way have less elasticity and are more likely to be damaged than those formed by only ordinary resin.
The pitch of the engaging portion (EorF) of either (A) or the inserted body (C) is set to be a multiple of the pitch of the other of the inserting body (A) or the inserted body (C). The insert body (A) is inserted while the mating portion (EorF) scrapes off the engaging portion (ForE) having a small pitch. Therefore, breakage is unlikely to occur.
