ABSTRACT:
A furniture structure utilizes a joint which allows three elongated members to be coupled orthogonally. In a preferred embodiment of the invention, the joint is utilized in a chair in which a first elongated member is a side rail, a second elongated member is a brace, and a third elongated member is one leg of the chair. The first member, which forms the side rail, has oppositely facing notches in each end thereof. A projecting tongue is formed between the oppositely-facing notches. The second member, which forms a brace, has a threaded insert therein and is received in one of the oppositely-facing notches in the first member. The third member, which forms a leg, has a notch therein and is received in the other oppositely-facing notch of the first member, while the tongue of the first member is received in the notch of the third member. A machine screw is passed through the third and first members and is screwed into the threaded insert of the second member to hold all three members together.
