Abstract
Abstract An article of furniture includes frame members, a seat member supported on the frame member, a concealed joint for pivotally coupling two frame members to each other, and an attachment for coupling the seat to the frame members. The two frame members include truncated bores for concealing the joint. The pivotal joint includes a pair of connecting members which are received in the truncated bores in fixed relationship to the frame members. Each connecting member has an opening for receiving a bearing member. A retainer is inserted through the bearing member and engages both connecting members to prevent lateral separation of the frame members. Each connecting member is independently rotatable on the bearing member. The seat attachment includes an opening in proximity to the edge of the seat member, a seat support member carried on the frame members, a slot in the support member having an upwardly facing shoulder, and a rod insertable through the opening in the seat member which seats on the shoulder to couple the seat member to the frame members.
