AHEIY'HE Patented May 1, 1934 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to folding chairs. It has for its purposes to provide a chair of extreme lightness, rigidity, and strength, and capable of folding into a compactness that renders it available for carrying to and from beach resorts, band concerts, or other places where such chairs are desirable for use.
Referring to the accompanying drawings which form a part of this specification and in which similar letters of reference refer to similar parts throughout the various views, Figure 1 shows a side view of my improved chair in set up position. Figure 2 shows a view of the side sections, in folded position, the hinged cross pieces, and
diagonal braces being in set up position. Figure 3 shows a top view of a part of two portions of the side sections, the whole of two other parts of said side sections, the hinged cross pieces and diagonal braces in set up position on the line 3-3 in Figure 1. Figure 4 shows the whole of all parts shown in Figure 3 in semi-folded position, the side sections being shown folded parallel. Figure 5 shows a plan view of the flexible seat portion and attached cross pieces which are adaptable to engage the tops of said side sections when the chair is assembled for use. Figure 6 shows an end View of the flexible seat and attached cross pieces shown in Figure 5. Figure '7 shows the chair in folded form for carrying.
Referring again to Figures 1, 2, 3, and 4, A and B, A and B show the component parts or the side sections which are hinged in pairs, A and B and A and B by the rivets C and C D and D show the cross pieces swivelled at their ends on the pins D and D and D and D hinged at their center at D and D and having fixed stops D and 3D in which register the slots D and ID for rigid locking. E and E show the diagonal braces extending from one side section A to the g other A in order to hold the sections firm and avoid side sway. The braces E and E are respectively swivelled at one end on the pins E and E and notched E and E at their opposite ends, which notches are adaptable to register and engage with the beaded pins E and ii. to add rigidity to the frame when the chair is in setup position. Spreader chains F and F are respectively secured to the portions A and B and A and B at F and F and F and F to tie the 5g side sections when in open position and avoid over-spreading of said sections.
Referring again to Figures 5, 6, and 7, G shows the flexible seat portion. G2 shows the fastening tab swivelled at G3 to the flexible top G and provided with a socket fastener G which fits over the button G H and I show cross pieces with engaging extensions H and H and I and I thereon, adaptable to engage the threaded pins A and A and B and B at the tops of the side sections A and B and A and B and locked in position thereon by the winged nuts A and N and B and B J and J show flexible loops secured t0 the seat portion which loops are respectively adaptable to flt over and encircle the portions 13 and B when the chair is assembled for 5 use.
Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States of America:-
A folding chair comprising two sets of side sections, each set consisting of two pieces pivoted crosswise intermediate the ends thereof, aplurality of cross pieces extending from one of said sets to the other, said cross pieces hinged midway their ends so as to fold upon themselves, and having locking means designed to positively hold said cross pieces in extended position, a plurality of braces adaptable to extend diagonally from one of said sets to the other, one end of said braces being pivotally hinged on one set and having means at its other end for looking with an element mounted on the opposite set, two cross pieces detachably engaging the tops of said side sets,
a flexible seat portion connecting said last mentioned cross pieces, two flexible loops secured respectively to the opposite edges of said flexible seat portion intermediate its ends, each respectively encircling one of the pieces of said side sections so as to hold said seat portion in its intended position, and create a crease in said flexible seat, said crease forming and indicating a line of demarcation between the seat and back portion of the chair when assembled for use, and two chain members, each connecting the respective lower ends of each pivoted side section to prevent the collapse of the chair in use.
KNUT W. OLSON.
