摘要： A folding chair construction comprising a plurality of substantially U-shaped portions, each having a pair of parallel side sections connected by a right angle corner member to a medial section, providing back and seat portions and front and rear legs hingedly connected for movement between a folded position, wherein all of the U-shaped portions are superposed with one another, and an erected position, wherein the U-shaped portions are relatively angularly disposed. The side sections of the back and seat portions and the medial sections of all portions are formed of tubular members connected for relative, telescoping movement between extended and retracted positions when the chair is in the unfolded and folded positions, respectively. A flexible fabric support portion is permanently secured to the back and seat portions by outwardly extending portions of the fabric which are looped around the side and medial sections and stitched to themselves. The width of the outwardly extending portions is not substantially greater than the lengths of the side and medial sections about which they are looped when such sections are in their retracted positions.

摘要： The chair of the present invention comprises a foldable frame of metal or other rigid material, comprising a fabric or plastic seat rest supported between a pair of tubes or rods, to the ends of which are hingedly connected a pair of telescoping tubular back supports, which, in open position extend upward, supporting between them in taut relation a backrest, also of fabric or plastic, which is further supported by a pair of X-pivoted braces and other braces connected to the telescoping tubular supports. Four stub legs support the seat rest in open position. A particular feature of the invention is that it is readily folded into an elongated configuration of narrow width, which may be fitted into a tube, by first folding the back and seat together, and telescopically extending the back supports, which simultaneously causes the X-pivoted braces and other braces to rotate into approximately parallel relation with the back supports.

摘要： A folding chair is formed of an integral tensile structure having eight articulated compression members with inner ends transfixed by a central ring. The outer ends of the compression members are joined by cables and a concave fabric seat to hold the chair in a usable position, one cable being released to collapse and fold the chair. To maintain the orientation of the ring on unfolding the chair, the inner ends of two compression members have engaged teeth formed thereon.

摘要： A collapsible support structure for supporting items, such as chair backs. The support structure, in an erect position, has two vertical members interconnected at their bottoms by a collapsible, preferably horizontal, member. Each end of the horizontal member is also pivotally connected to the other vertical member by a diagonal support member that extends between each end of the horizontal member and an upper portion of the opposite vertical member. When the structure is erect, the diagonal support members form an "X". Stiffening members, which are preferably generally vertical, are spaced from the vertical members and extend between the horizontal member and the diagonal support members. Both the horizontal member and the diagonal support members are formed of a plurality of pivotally interconnected links, at least one of which is modified to maintain the links in a desired angular position when the support structure is erected. Collapse of the support structure moves the vertical members towards each other to reduce the width of the structure. The collapsible support structure is combined with similar or other types of support structures to form folding devices.

摘要： A folding chair, especially a wheeled push chair for a child, comprises a pair of similar side frames of interpivoted bars and cross-members integral with the side frames, the cross-members having only intermediate hinges which come into coaxial alignment when the side frames are folded and the side frames can then close together like a book.
