This invention relates to a collapsible stool of which the various elements can be assembled and disassembled, and fan ob ect.

ofthe invention is to secure a knock-down stool of great strength and rigidity.

Another object isto provide "a construction that will enable anyoneto very quickly 1 assemble or disassemble the various elements of the stool. a I I I The accompariaying drawings illustrate the invention. I g ,1-

Figure 1 is a perspective view of a stool constructed in accordance withthe"provisions of this invention, a-portion of the seat cover being broken away." i Fig. 2 is a sectional elevation of the stool. Fig. 3 is an enlarged sectional detail of one corner of the stool. v

Fig. 4. is an enlarged sectional'detai'l of the middle portion of the seatand the post. Fig. 5 is an enlargedsectional-detail of 'a portion of one of the legsand a portion of one of the braces engaging the same.

Fig. 6 is an enlarged sectional detail of the lower portion of the post and the middle portions of the braces, showing the connec- 7 tion therebetween.

Fig. 7 is a plan view of the seat collapsed. Fig. 8 is a longitudinal view, partly in section, of one of the le s. V Fig. 9 is a longitudinal view of one of the I braces. I I

Fig. 10 is a longitudinal view of the inner post member. Fig. 11 is alongitudinal view of the outer post member.

There is provided a seat other at'their ends as indicated at 14. Pivoted at 15 to the opposite side members 13' The pivots 14 project a substantial dist ance below the under faces of the members zen of the United States, residing at Los- 12 comprising four side members 13 pivoted to one an- '13 and, when the seat parts are in position to form a rectangle, the pivots 1 1 .are adapt ed to be received in the tubular 11131361 ends of legs '18 which are preferably curved to a slight extent attheir lower ends as indicated at 19 .j I I l The inner sides of the legs 18are provided with slots 20 of suiiicient length to admit the insertion into the slots of the ends of braces 21. There are two braces 21- and said braces are arranged diagonally relative to the rectangular seat 12 and each brace is adapted to engage} diagonally opposite legs 18. In order to I prevent spreading apart of the legs 18, the braces 21 are provided near their ends with notches22 in their upper edges so as to hook beneath the upper edges of the slots 20. I e

h The braces 21' are formed of strip spring metal and are shaped so that the middle portions thereof lieat a rightangle to the endportions to make the middle-portions parallel with the seat members 16 which may also be of strip metal Thebraces 21 areprovided centrally with perforations28; The pivot 17 constitutes a tie rod as it is sufliciently longto extend from the seat 12 through the perforations23 and project beneath the crossed braces 21. The pivot 17 passes loosely through perforations 171 in the seat members 16 and is provided with a head 172 to seat against the upper face of the uppermost seat member 16. The pivot 17 is screw-threaded at its lower end, as indicated at 24, to receive a wing nut 25 which bears againstv the under brace 21 so as, to force the braces upwardly to hold them with their notches 22 hooked securely into the legs 18 and to hold the legs and seat assembled.

Means are provided to limit upward motion of the middle portions of the braces 21 so that the legs 18 will not be bent inwardly I of the upper brace 21. The member 26 is a preferably ofv such length that, when the Wingnut 25 is tightened to holdthe seat and bracestoward one another, said braces will be slightly sprung or bowed v upwardly at their middle portions so as-to be under tension. This tension tends to preventthe braces from disengaging the legs 18.

- If desired, the seat 12 maybe provide'c't with a. suitable fabric cover comprising-atop 5 jecting end of the pivot 17 andthestraight ends of the legs 18 will be slipped over-the pivots 14. Then the braces 21 will ;be;pla( :ed with, their perforations 23 engaging the projecting end of the pivot17and with their notches 22engaging the legs 18; Then the Wing nut 25 Will be; applied to .the post member 17 a-nd'tightened to slightly bow-the braces upwardly and securely clamp them to the legs.

The stool will then be turned into upright position. If it be desired'to ruse the-pseat cover-27, said cover may he slipped over the seat 12.; When the, foregoing operations have been completed --.the parts will be; as;

sembled'as shown in Fig. 1; l-\-reversal of the. above describedoperations will place the parts in the knock-down condition.
