By doing so, the first wood 100, the second wood 200, and the third wood 300 can be joined in a state where they are crossed. By repeating such operations, the worker can easily assemble the box-shaped frame.

図１～４、及び８に示すように、第一の木材１００と第二の木材２００と第三の木材３００が接合された状態から、作業者は、薄板４００を蟻溝６００から引き抜き、蟻ほぞ３１０を蟻ほぞ穴５００から引き抜き、相欠部２１０と相欠部３１０との重なりを解除することにより、本例の接合構造を分解することできる。このような作業を繰り返す事により、作業者は、箱形の枠の分解を容易に行うことができる。 As shown in FIGS. 1 to 4 and 8, from the state in which the first wood 100, second wood 200, and third wood 300 are joined, the operator pulls out the thin plate 400 from the dovetail groove 600, and The joint structure of this example can be disassembled by pulling out the tenon 310 from the dovetail mortise 500 and releasing the overlap between the phase cutout 210 and the phase cutout 310. By repeating such operations, the operator can easily disassemble the box-shaped frame.

図８に示すように、本例の接合構造により構成された箱形の枠は、金具等を用いないため、製造に必要なコストが低く、意匠性が高い。 As shown in FIG. 8, the box-shaped frame formed by the joining structure of this example does not use metal fittings, so the manufacturing cost is low and the design is high.

本発明の接合構造において、第一の木材、第二の木材、第三の木材、及び薄板の形状は、本例に限定されない。例えば、第一の木材、第二の木材、第三の木材、及び薄板の長さ、幅、厚さ、及び蟻形の角度は、本例に限定されない。また、例えば、第一の木材、第二の木材、及び第三の木材が交差する角度は、直角でなくともよい。また、例えば、第一の木材の蟻ほぞ穴形成部と第二の木材の蟻ほぞ穴形成部とにより形成された蟻ほぞ穴のうち、第一の木材の蟻ほぞ穴形成部に第三の木材の蟻ほぞの基端側が嵌め込まれ、第二の木材の蟻ほぞ穴形成部に第三の木材の蟻ほぞの先端側が嵌め込まれる構造としてもよい。また、例えば、本発明の接合構造により構成された箱形の枠の形状は、図８に示す例に限定されない。 In the joint structure of the present invention, the shapes of the first wood, second wood, third wood, and thin plate are not limited to this example. For example, the length, width, thickness, and dovetail angle of the first wood, second wood, third wood, and slats are not limited to this example. Further, for example, the angle at which the first wood, the second wood, and the third wood intersect may not be a right angle. Further, for example, among the dovetail mortises formed by the dovetail mortise forming portions of the first wood and the dovetail mortise forming portions of the second wood, the third wood may be attached to the dovetail mortise forming portion of the first wood. It may also be a structure in which the proximal end side of the dovetail tenon of the wood is fitted, and the distal end side of the dovetail tenon of the third wood is fitted into the dovetail mortise forming portion of the second wood. Further, for example, the shape of the box-shaped frame formed by the joining structure of the present invention is not limited to the example shown in FIG. 8.
