' FOLDING s'roon' v Application filed September 4,119262 se'riarnb. 133,584.

My invention relates to a new and useful improvement inia folding stool andhas for 3 its object the provision of a stool having supporting legs and seat supporting arms foldable in parallel relation toeachother for packing to a small space and adapted for. L v p at their inner ends and-at theupper surface;v 1

extending angularly outwardly in opposite -directions from a centralysupportlng mem her when 1n operative positlon.

Another object of the invention is the provision in'a stool of this class of a flexible seat'. forming member swingably' mounted. on a supporting arm and adapted --fon-folding 1 around the supporting arms andsupporting legs when in collapsed form soasto provide a covering for the same.

' Another object'of the invention is the provision. of a folding stool of this class of-a .supporting member having engagement members mounted thereon forlimiting the 3 pivotal movement of the supporting arms relatively thereto in one direction and so constructed and arranged as to limit the piv- -otal movement of the legs-so as to limit their spreading relatively to their supporting member. r L v Another object of the invention 1s the pro- 1 vision of a flexible seat forming member having a rigid rib at one side hingedly connected to a supporting arm to retainthe .fiexible seat forming member in distended position.

' (scribed and claimed.

Other objects will appear hereinafter.

The invention consists in'the combination: parts hereinafter de and arrangement :of

The invention will be best understood by which form a 40 vention in collapsed form.

As shown in the drawings the invention comprises av flexible seatforming member 7 having its edges doubled over, to provide sleeves 8'in whichjis extended a suitable reinforcing member 9, suchas a'chain', cable,or

the like, this chain or cable being exposed at part of this specification and *the corners [and-carrying securing rings '10" andlllr A supportingblockis provided having the arms 12, 13 and 14 which meet at V a common center and .i'project outwardly therefrom at angles to each other.. =Projectingoutwardly fromthearms'12, l3, and 14;

thereof are flanges 1'5 In the form shown Lhave three supportingarms:16,17 and 18, each of which is. p ivotally; connected .to the {supporting arms 14, 12 and 13 respectively, asuitable respective armsf12,13 and 14.,

parallel relation with each other; .1 -Pivot ally mounted on the same bolt and on each of the I arms 12, 13 and 14,. at the [opposite side thereof, are supportinglegs 19, 20 and"21. As shown in Fig. 2 these legs arenadapted.

the supporting arms 16,17 and 18. [These legs as, clearly appearsfrom F 1g; 4 are so also fOI' folding into Parallel relation" with i mounted on the arms 12, 13 and 14 that their ends engage against the inner ends of "ad- Jacentarms to limit their spreading when moved to operative position. I v It will be notedithat the arm '18is of less length'than the arms "16-and 17. Hingedlymounted intermediate its ends onthe free end of the arm 18 1s arigidbrace or; rein-, forcing member 22, which-1s secured to the fiexible'seat' forming member'- 7 so a s'to re}, tain the seat forming member in outwardly spread position- The brace 22 is adapted,

Each of the arms 16 and His provided loo on its free end with an'axially extending slot 23, a finger 24,'extend-ing upwardly from the slot 23 and therings'lOand 11, engaging in the slots 23, these-"rings when engaged in; j ,thisslot serving to retain theflexible-seat forming member] in; tautly stretched condi-' tion. This fabric serves to retain the arms. I
