The engaged member (20) can be fixed to 1). Furthermore, since the groove (50) is formed so that the operation head of the fastening member (61) can be housed inside the groove (50), the operation head of the fastening member (61) is formed inside the groove (50). And does not protrude and appear on the surface of the projection (40). As a result, it is possible to reliably engage both the concave portion (30) and the convex portion (40) without generating a gap between the concave portion (30) and the convex portion (40), which may cause loosening and rattling after the engagement. Further, since the operation head of the fastening member (61) is hidden, the operation can be easily and safely performed without being caught by the operation head protruding during the operation.

Further, since the groove (50) is formed, when the fastening member (61) is screwed in, the leading end of the fastening member (61) can be reliably guided, and the screwing of the fastening member (61) can be performed. There is no displacement. Thereby, the assembling work can be facilitated. According to a third aspect of the present invention, in addition to the features of the first or second aspect, the engagement member (10)
Is inserted into the groove (50) in order to adjust the position of the expanding member (60) inside the groove (50) with the engaged member (20) fitted in the engaging member (10). A possible operation hole (70) is provided.

According to the present invention, since the operating hole (70) is formed in the engaging member (10), the operating member (20) is expanded when the engaging member (10) and the engaged member (20) are engaged. The position of the member (60) can be adjusted. That is, when the engagement member (10) and the engaged member (20) are engaged, the dimensions and the shape are set so that the projection (40) can be easily inserted into the recess (30). And keep
The frictional resistance between the two can also be set small. Then, after inserting the convex portion (40) into the concave portion (30), the independent convex portion (41) is expanded right and left, the frictional resistance between the two is changed to a large one, and the engagement between the two is increased. Can be made strong. This makes it possible to obtain a large frictional resistance, which can never be obtained when the fitting is performed after adjusting the frictional resistance of the two, and it is possible to securely and firmly engage.

According to a fourth aspect of the present invention, in addition to the features of the first, second or third aspect, the engaging member (10) and the engaged member (20) are arranged in the longitudinal direction. An extruded product of a thermoplastic resin having the same cross-section, which is formed along the longitudinal direction on the inner surface of the concave portion (30) and the outer surface of the convex portion (40), and is formed inside the concave portion (30). It is characterized in that a sawtooth-shaped uneven portion (80) having a sawtooth-shaped vertical cross-section that can be fitted to each other when the portion (40) is inserted is formed.

According to the present invention, a saw-toothed saw-tooth uneven portion (80) that can be fitted is formed on the inner surface of the concave portion (30) and the outer surface of the convex portion (40). For this reason, when the convex portion (40) is inserted into the concave portion (30), both can be fitted at any position in the region where the serrated irregular portion (80) is formed. Thereby, the fitting position of the convex part (40) inside the concave part (30) can be adjusted.

Then, at the time of extrusion when making an extruded product,
Normally, the flowing speed, direction, and temperature of the molten thermoplastic resin are apt to change, but the formation of the saw-tooth irregularities (80) along the longitudinal direction prevents the movement of the molten thermoplastic resin. The speed and direction of the flow of the thermoplastic resin can be kept constant. As a result, the temperature change is likely to be uniform and stable, and defective products are less likely to occur in the finished molded product.

There is no slippery feel on the surface of resin, vinyl chloride, or the like, and a good feel that fits comfortably in the hand can be obtained.

Further, the engaging member (10) and the engaged member (20)
Is made of the above-described materials and has a resin, so that it has less water absorption and does not shrink due to moisture absorption as compared with a wood material. As a result, it is possible to obtain a material which is less likely to be warped, twisted, and harder to rot than wood, and has excellent uniformity as a material. According to a sixth aspect of the present invention, in addition to the features of the first, second, third or fourth aspects, the engaging member (10) and the engaged member (20) are made of a cellulose-based material. It is characterized in that it is formed so as to have a grain pattern by coloring and molding a resin mixed with a powder having a smaller diameter than the fine powder and carrying a hard fine powder on the surface of the fine powder of the material. .

Here, since the "engaging member (10)" and "engaged member (20)" are made of the above-mentioned materials, a grain pattern can be formed on the surface thereof. In addition, in the case of woody materials, there is a variation in quality due to a difference between natural wood as a raw material and a difference in water content, but the `` engaging member (10) '' or `` engaged member (20 ) "Does not have such a problem and can suppress the variation of products.
That is, since the molded article molded using the above-described material has a wood grain pattern even if it has a complicated cross-sectional shape, a wooden material or a material having a woody texture replacing it was used for other surface members in the room. In some cases, it is suitable for use in the sense of harmonizing the appearance design. In other words, it is possible to provide a molded product having a wood grain pattern, even if the member has a cross-sectional shape that would require much time if natural wood is cut.

[0024] Since it is made of "resin mixed with powder", it is harder to absorb moisture than ordinary woody material. Even if moisture adheres, it is sufficient to wipe off moisture and maintenance can be facilitated. Things. That is, even if dirt such as hand stains adheres to the surface of the decorative material, it can be cleaned with a wet cloth, and after removing the dirt, it is sufficient to wipe off the moisture. This makes it possible to present a wood grain pattern in appearance and to have the same appearance as a wooden product, but with respect to water resistance, the engagement member (10) and the engagement member are much more resistant to water than the wooden product. A composite member (20) can be provided.

Here, the term "cellulosic material" includes natural wood, sawdust, rice straw, bacas and the like. The term “fine powder having a smaller diameter and a greater hardness than the fine powder” refers to fine powders of titanium oxide, ferrite, aluminum, nickel, silver, ceramic, calcium carbonate, and the like.

The material for "coloring the resin" is a colored pigment, for example, an inorganic pigment such as iron oxide, cadmium yellow, or carbon black. Also, "presenting a wood pattern by coloring and molding the resin" means that the resin itself is colored using the above-described pigment, so that it is formed not only on the surface but also inside so as to present the wood pattern. Is what you are doing. Thereby, even if the surfaces of the engaging member (10) and the engaged member (20) are repeatedly contacted with the surrounding peripheral members and worn, the grain pattern of the surface does not disappear, and a good grain pattern is obtained. Appearance can be maintained.

Here, the "resin" includes the same one as described in claim 5.

In the center of the projection 40 of the engaged member 20,
A groove 50 is formed along the longitudinal direction, and the groove 50 is formed.
Extends downward. Therefore, when the screw is screwed in while rotating the tip of the fastening member 61, the tip of the fastening member 61 can be reliably guided downwardly of the groove 50 without swinging around the groove 50 and coming off. That is, as compared with the case where a V-groove is formed on the surface as a guide groove for the fastening member 61, the tip of the fastening member 61 does not swing and damage the surface of the engaged member 20, The screwing work of the fastening member 61 can be reliably performed, and the on-site construction can be facilitated.

Further, since the engaging member 10 and the engaged member 20 are made of the above-mentioned materials, a grain pattern can be formed on the surface thereof. In addition, in the case of wood materials, there is a variation in quality due to a difference in natural wood as a raw material, a difference in water content, and the like.
This is not the case with the engaged member 20 and the variation in the product can be suppressed. That is, a molded article molded using the above-described material exhibits a wood grain pattern even if it has a complicated cross-sectional shape, so that the appearance design can be harmonized with “wood”. In other words, it is possible to provide a molded product having a wood grain pattern, even if the member has a cross-sectional shape that would require much time if natural wood is cut.

Since it is made of a resin in which powder is mixed, it is harder to absorb moisture than ordinary woody materials. Even if moisture adheres, it is sufficient to wipe off moisture and maintenance can be facilitated. is there. That is, even if dirt such as hand stains adheres to the surface of the decorative material, it can be cleaned with a wet cloth, and after removing the dirt, it is sufficient to wipe off the moisture. This makes it possible to present a wood grain pattern in appearance and to form the same appearance as a wooden product, but with respect to water resistance, the engaging member 10 and the engaged member are much more resistant to water than the wooden product. 20 can be provided.

Since the engaging member 10 and the engaged member 20 use the above-described pigment to color the resin itself,
It is formed so as to exhibit a wood grain pattern not only on the surface but also on the inside. Thus, by repeatedly opening and closing the sliding door 84 many times, the upper portion of the sliding door 84 and the engaging member
Even if the contact member 10 or the engaged member 20 is repeatedly contacted and worn, the grain pattern on these surfaces does not disappear, and a good appearance of the grain pattern can be maintained.

In the first to third embodiments, different materials are used for the engaged member 20 and the engaging member 10 in each embodiment as described above. The material used is not particularly limited to the materials described above, and the materials described in each embodiment can be used in other embodiments.
Further, the member may be made of only ordinary resin other than the above-mentioned materials. Further, the manufacturing method of each member is extrusion molding in the above description, but is not limited thereto, and may be ordinary injection molding.
