发明名称 COLLAPSIBLE CHAIR
摘要 The invention resides in a collapsible chair which is adapted to fold into an elongated rectangular package, the chair being collapsible in two dimensions, simultaneously. A pair of upright rigid support members are connected to a foldable arm at the center thereof. A plurality of rigid support legs are collapsible in a scissor action which supports the center or weight support material. A seat brace is connectable from the lower portion of the rigid support members to interlock with a connector plate disposed on the lower end of a front brace, when the chair is opened to its stable position. The connecting of said seat brace to said plate provides the locking means for holding the chair in its stable condition and further provides the necessary rigid crossmember construction to support the body of the user. A foldable member is connected between the lower portions of the rigid support member to maintain said support members in spaced relationship when excessive weight is positioned on the chair.
