ある。 However, as shown in FIG. 4, this screw fixing is achieved by inserting a decorative bolt 4 through the hole from above the seating portion 2a, and interposing a spacer 5 to bend it when seating and make it more comfortable. It was inserted into the hole in leg 1 and screwed with nut 6.
Therefore, the screw head is exposed on the surface of the seating portion 2a, which is unfavorable in terms of appearance, and also makes it uncomfortable to sit on as it touches the body. Additionally, if the screws become loose, clothing such as stockings may get caught in the gap and be torn.

よつて、本考案はねじ頭が着座部表面に露出し

る。 Therefore, an object of the present invention is to provide a resin-impregnated chair in which the screw heads are not exposed on the seating surface.

とを特徴とする。 The present invention is a chair made of resin-impregnated plywood in which a seating part formed of resin-impregnated plywood is screwed to the upper surface of the metal legs. A resin-molded screw seat was installed in which the insert nut was embedded, and was bonded by heat and pressure at the same time as the seat was hot press molded, and the bolt was screwed into the insert nut through the hole at the corresponding position on the top surface of the leg. It is characterized by

加熱により接着される。 In FIG. 1, reference numeral 10 denotes a truncated conical screw seat, which is molded from a synthetic resin material and has an insert nut 11 embedded therein. This screw seat is created when the chair body 2 made of resin-impregnated plywood is hot-press-molded into the seating part 2a and backrest 2b having the shape shown in FIG. 2 using a mold using a heat press machine. Bonded by heating.

に部品数が減少する。 When assembling the chair, the chair is attached by screwing the bolt 15 into the insert nut 11 from below through a conventional screw hole in the upper surface of the metal leg 1 with a washer 16 interposed (FIG. 2). As a result, the head of the bolt 15 is not exposed to the surface, so there is no need to use a cosmetic. Since the screw seat 10 also functions as a spacer, the number of parts is reduced.

安価に形成可能である。 As described above, according to the screw fastening structure of the present invention, the screw head is not exposed on the upper surface of the seating portion, so the appearance is improved and the seating comfort is also improved. Also, there is no need to worry about clothes getting caught due to loose screws. The screw seats are integrated without adhesive at the same time during heat press molding of the chair body, making it easy to use multiple screw seats at the same time.
It can be formed at low cost.
