【考案の詳細な説明】 〔産業上の利用分野〕 本考案は木工部材類の継手構造、さらに詳細には周方向
での位置の決まった部材に好適な継手構造に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a joint structure for woodworking members, and more particularly to a joint structure suitable for a member whose position in the circumferential direction is fixed.
〔従来の技術とその技術的課題〕 木工製品はノックダウン方式で組み立てられることが多
い。この場合、当該木工製品が円形断面であるような場

相対回転させればよいため、継ぎ作業は比較的容易であ
る。[Conventional technology and its technical problems] Woodworking products are often assembled by a knockdown method. In this case, if the woodworking product has a circular cross section, since there is no directivity in the circumferential direction, a nut is arranged on one member and the screw member is projected from the other member to rotate both members relative to each other. Therefore, the joining work is relatively easy.
ところが、デザインや外観が重視される傾向に伴い、部
材の断面を真円以外の異型たとえば瓢箪形とか多角形な

ような場合には手摺り部材を分割して長手方向で継ぐこ
とが必要となる。後者の例としてはコーナーが角形をな
したテーブルに同じ断面形状の脚を取付けるような場合
がある。However, due to the tendency to emphasize design and appearance, the cross-section of the member is often formed into an irregular shape other than a perfect circle, for example, an angular shape such as a gourd shape or a polygonal shape. For example, as an example of the former, if there is a handrail on a staircase, and if a curve or slope is to be changed in the middle of a handrail with a constant span, the handrail members can be divided and spliced in the longitudinal direction. Will be needed. As an example of the latter, there is a case where legs having the same cross-sectional shape are mounted on a table whose corners are square.
このような特殊断面の両部材を断面形状を合致させて継

ぐり穴に挿入し、木ねじ部を相手方の部材にねじ込み、
機械ねじ部にワッシャとナットを螺合して締め付けてい
た。When joining both members with such a special cross-section with matching cross-sectional shapes, conventionally, in general, a deep counterbore hole is formed from the bottom side of one member to the inside, and both members are abutted,
Insert a screw member that has a wood screw part and a mechanical screw part formed in half into the counterbore hole, screw the wood screw part into the other member,
A washer and a nut were screwed onto the machine screw to tighten it.

いう問題があった。However, with this structure, it is necessary to form deep counterbore holes in each member, which increases the number of processing steps.Besides, it is necessary to insert a tool such as a wrench or a screwdriver into the counterbore holes to perform screwing operation. However, there was a problem that it was very troublesome, inefficient, and the joint strength was likely to be lowered due to a work mistake. In addition, since there is a deep counterbore, there is a problem that a hollow noise is generated only at that portion when hitting, and it cannot be applied to joining members having a small cross-sectional area.
