  • the present invention relates to" folding chairs and, more particularly, to folding chairs of extremely simple design which also may be stacked when in unfolded condition.
  • One type of prior art folding and stacking chairs generally contains a U-shaped member which supports the back and has the front legs at the ends of its parallel sides.
  • the sides of the U-shaped member are articulated with the back legs and are provided with a means of support for the surface of the seat which is also appropriately articulated for folding.
  • the folding and stacking chair which is the subject of the present invention has been devised, in contrast to what is already known, offering a structural solution in that one of its parts has a multiple function.
  • the chair has a central cross member which. besides connecting its back legs, simultaneously acts as a support for the seat which is a panel articulated with the U-shaped member.
  • the folding and stacking chair may be said to be essentially characterized by a pair of U-shaped members and a seat.
  • the first U-shaped member supports the back of the chair at the closed end thereof and the sides of the member at the open end serve as front legs.
  • the sides of the second U-shaped member at the open end thereof serve as the back legs of the chair.
  • the two U-shaped members are articulated to one another and the seat is also articulated thereto along the same axis as the first articulation.
  • the seat is mounted so as to unfold as far as the cross member of the second U-shaped member connecting the back legs, said cross member also providing lateral support.
  • FIG. 1 is a perspective view of a chair when unfolded.
  • FIG. 2 is a side elevation of the same chair when folded.
  • FIG. 3 is a detail drawingshowing the arrangement of the articulations between'the individual parts.
  • FIG. 4 is a detail drawing of a second embodiment of one of the parts of the present invention.
  • FIG. 5 is a detail drawing of a third embodiment of one of the parts of the present invention.
  • FIG. 6 is a detail drawing of a fourth embodiment of one of the parts of the present invention.
  • FIG. 7 is a perspective viewof a detail of another embodiment of the present invention.
  • FIG. 8 is a perspective view of a detail of yet another embodiment of the present invention.
  • the folding chair which is the subject of this invention consists of a pair of members 1 and 2 doubled over to form U- shapes and a seat 3, which together enjoy an articular relationship at points 4 and 5, located on the sides of said seat surface.
  • Member 1 divided at articulation points 4 and 5 defines the front legs Ia and 112, respectively of the chair and the back frame 1c which in turn supports the back Id.
  • this member 2 can be varied selectively and according to need, as follows: it can be bent and articulated directly (FIG. 3) or the cross member or support 2c and its integral legs 2a and 2b can be independent parts which form'said member2; in the latter case, the parts I are linked by means of a pair of intermediate connecting elements such as 6 and 7 or 8 and 9 (FIGS. 4 and 5), which at the same time and in both cases, are also articulated with member 5; it can be fastened firmly to the cross member or support 2c to give the configuration of a tray with projecting ends 10 and 11 (FIG.
  • the cross member or support 2c is mounted in aplane perpendicular to the ideal vertical plane passing through the plane of the articulation of the chair or optionally in a plane at a slight angle with respect to the cited vertical plane and in either case must also be at the correct angle in order to support seat surface 3 when the chair is unfolded.
  • a folding and stacking chair comprising:
  • first U-shaped member having two parallel arms and a cross member at one end thereof, the open ends of said arms serving as the front legs of the chair and the cross member serving as the back of the chair;
  • a second U-shaped member having two parallel arms and a cross member at one end thereof, the open ends of said arms serving as the rear legs of the chair, said second U-shaped member being articulated to said first U-shaped member such that said second U-shaped member is pivotable about a fixed axis passing through the arms of said first U- shaped member;
  • a folding and stacking chair in accordance with claim 1 wherein the arms of the said second U-shaped member are curved to an angle approximately perpendicular to the plane of said arms and wherein said curves are near the cross member end of said arms, and further wherein the points of articulation of said second U-shaped member with said first U-shaped member are located at the curved portion of said second U-shaped member.
  • a folding and stacking chair in accordance with claim 4 wherein said cross member is in the shape of a tray and wherein said intermediate connecting means comprise projections integral with said tray connecting with said arms.
  • a folding and stacking chair in accordance with claim 1 wherein said cross member is in the same plane as the arms of said second U-shaped member and wherein said second U-shaped member further includes projections connected to said arms near said cross member end thereof and wherein the points of articulation of said second U-shaped member with said first U-shaped member are on said projections on the end thereof remote from said arms of said second U- shaped member.
  • a folding and stacking chair in accordance with claim 1 wherein the arms of said second U-shaped member are outside of the arms of said first U-shaped member and wherein said seat is positioned inside the arms of said first U-shaped member.
