BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden spigot.

[0002]

2. Description of the Related Art Conventionally, a wooden driving stopper has been designed so that a wooden driving stopper with an adhesive applied to the outer periphery is driven into a continuous perforation. When the wooden driving stopper was driven into the continuous perforation, the outer periphery of the wooden driving stopper and the inner wall surface of the continuous perforation were formed so as to be in close contact with each other. Most of the adhesive applied to the outer periphery of the wooden spigot leaks to the outside from the continuous perforation, which is a problem because the adhesive effect is reduced. Therefore, an improved wooden spigot having a plurality of longitudinal grooves or a plurality of spiral grooves formed on the outer periphery has been developed. The improved wooden spigot is
It was as follows. There was a rod-shaped wooden spigot (FIG. 9) provided with a plurality of longitudinal grooves 10 on its outer periphery. As shown in FIGS. 7 and 8, when this wooden driving plug is driven into the continuous perforation 2 provided in the joint 1 of the plurality of wooden members A and B, the inner wall surface of the continuous perforation 2 and the outer periphery of the wooden driving plug are inserted. A tunnel-shaped space is formed therebetween, and both ends of the tunnel-shaped space are opened to the outside. Since the plurality of grooves 10, 10 of the driving plug are cut by a cutting tool, the surface is damaged. There was a rod-shaped wooden spigot (FIG. 10) provided with a plurality of spiral grooves 11 in the longitudinal direction on the outer periphery. FIG.
As shown in FIG. 8, when this wooden driving plug is driven into the continuous drilling hole 2 provided at the joint 1 of the plurality of wooden members A and B, a tunnel is formed between the inner wall surface of the continuous drilling hole 2 and the outer periphery of the wooden driving plug. A spiral space is formed, and both ends of the tunnel-shaped spiral space are open to the outside. Since ancient times, when joining wooden products such as wooden buildings and furniture, the joints were hand-formed one by one and tightly fitted, so that the joints could be firmly joined. However, in recent years, in accordance with the progress of wood processing technology and the strong demand for shortening the manufacturing cycle, those wooden members have been machined in advance, so that the joints are loosely fitted and the loosely fitted Wooden spigots have come to be used heavily to reinforce the joints. The wooden driving stopper is reinforced by applying an adhesive (not shown) to the outer periphery and driving the wooden driving plug into the continuous perforation 2 to fix the plurality of wooden members A and B joined at the joint 1. It has been developed to prevent the wooden members A and B from falling off or coming off.

[0003]

However, the above wooden spigot has the following problems, and an early solution thereof has been desired. As described above, when a wooden spigot is driven into the continuous perforation, a tunnel-shaped space is formed between the inner wall surface of the continuous perforation and the outer periphery of the wooden spigot, and both ends of the tunnel-shaped space are opened to the outside. Therefore, most of the adhesive applied to the outer periphery of the wooden spigot flows out and leaks from the opening of the tunnel-like space, and the desired adhesive effect cannot be obtained, which is a problem. Was. Also, like a groove of a wooden driving plug, a groove cut by a cutting tool does not return to the state before the groove is formed even if the applied adhesive permeates the base, and the groove does not return. Is still
The adhesive in the groove, which could not penetrate the base material, dried to form a layer, and the adhesive strength was greatly reduced, which was a problem. It is a well-known fact in the industry that this layered adhesive is peeled off as a layer and has no adhesive strength. Further, when a groove is formed on the outer periphery of a wooden driving plug with a cutting tool, the cutting tool is severely damaged by wear, which is an obstacle to cost reduction. The problem to be solved by the present invention, in view of the above disadvantages,
A wooden driving stopper that prevents the adhesive applied to the outer periphery of the wooden driving stopper from leaking out, and restores the groove where the adhesive has permeated to the state before the groove was formed, and can fully exert the adhesive effect of the adhesive. It is intended to provide.
