I Application. and August 18, 1925; m it; $0,888. i

The invention relates.- to chairs, more par- I ticularlyof the folding or collapsible type designed generally to be stored away when not in use. 1 It has forits object. to rovidc a chair of this character which w e comparatively light shall 'be' sufliciently rigid I and of such substantial construction as to support comparatively heavy loads. The invention has for a further object .to' so con struct the novel chair-that the same shall occupy but a minimum space whereby stora e ofthe same may readily be accomplished which Fig. 1 is -a side elevation of the novel chair inextended position and ready for use.

Fig. 2 is a front elevation, and Fig. 3 1s a. lan thereof. I I ig'. 4 is a side elevation of the chair in collapsed condition. 1

shown as-constructed-essentially of a pair of front legs 10 and a pair of-rearlegs 11 hinged intermediate their ends about a rod 12, a seat .13 anda back 14. The lower ortions of the rear legs are slightl longer an thecorrespondingportions of t e front legs. A pair of arms 15, moreover, pivotally connect the seat and back at the respective sides thereof; each of said arms being offset for a portion of its length to strengthen the chair a ainst-lateral play. 'A'seat supportingro 16, also, extends between the legs and is-carri'ed thereby beneath the seat 13 to support thelatter, whilebracingjrods 17 and 18 are mounted between the rear legs and a similar rod 19 between the front legs.

' The upperends of the two irear legs 11'are pivotally connected to the forward portion of seat 13 while the upper ends of the front legs 10 or rather extensions thereof are pivotally secured to the back 14, said extension portlons being located outside of the arms 15. The saidarms, moreover, are provided along the lower edge'and between the ends ment of the seat 13.

nection with the accompanying drawings, in,

Referring to the drawings, the chair is' with'hooks or stop members20 which are desl ed to engage with the seat sup orting rod 16 and limit thereby the forward move- The seat 13 as well as the back 14 may 00 be provided with suitable cushion members 21 and 22 respectivel' and the frames form ngsaid seat and back members may be made identical, thereby requiring but one die in the manufacture of the same. At "the back of the seat member, moreover, as well as at the topof the back member there are provlded respective hand holes 23 and 24, the former being for use in grasping the seat in 1 collapsmg and setting up the same asv heremafter set forth 5 while the latter is for convenience in movm the chair about.

It will be no that there is no contintuous frame member from the bottom to top of chair. as is the usual practice in connec- 76 tron-with theconstruction of camp chairs and the like; but the construction hereinfset forth is such that the chair may be readily collapsed merely by graspingthe same at the hand hole 23 and" then bodily -lifting the chair with a slight upward turn. This will cause the hooks 20 to become disengaged from the seat supporting rod 16 and will cause the back 14 to fall over on the seat in moving about the pivot points 25, said back also about the outer ends of arms 15 whlle at the same time the legs 10 and 11 close in about the rod '12. The chair then assumes the form shown in Fig. 4 with all parts substantially within the width of the side of front legs 10 and with back 14 inverted over seat 13 as shown, which. has moved upwardly about the top of the rear legs 11. The hand hole 23 is then also uppermost, and affords a convenient means for carrying the chair about while collapsed. In this collapsed condition, the seat occu-f pics but a comparatively small space and is substantially flat so that there is no lossof space in storing one chair upon the other." In setting up the chair again, it ismer:

sary merely-to grasp the back portion at the hand hole 23 and guide the collapsed chair to brin the rear legs (which are slightly longer t an the front le as aforesaid) into contact with afloor, w ereby with a slight downward pressure thereon the parts will fall into, position until the movement is stopped by contact ofthe rod 16 with the hooks 20, the chair then assuming the posi- 110 'tion shown in Fig. 1 and in "which the upper edge of which back member the rear of the seat member projects, a rod extending beneath the seat member and connecting the front pair of legs, and arms between the seat and back member providing a hinged connection therebetween, said arms having means extending therefrom for engaging the said rod.

2. A collapsible chair, comprising a rear pair of legs, a front pair of legs pivoted thereto between the ends thereof and extending above the upper end of said rear pair of legs, a seat member pivoted to the upper end of the rear pair of legs, a back member pivoted to the upper end of the front air of legs, the seat member having a handle at the rear projecting beyond the bottom ed e of the back and whereby the chair may be grasped for collapsing and also for setting in position for use, a rod extending beneath the seat member and connecting said front pair of legs, and arms between the seat and back member providing a hinged connection therebetween, said arms having means extending therefrom for engagin the said rod.

3. X collapsible chair, com rising a rear pair of legs, a front pair 0 legs pivoted thereto between the ends thereof and extendin above the upper end of said rear pair 0 legs, a seat member pivoted to the upper end of the rear pair of legs, a back member pivoted intermediate its length to the upper termination of the front air of logs, the seat member having a hand e ortion at the rear projecting beyond the ottom edge of the back and whereby the chair may be grasped for collapsing and also for setting in position for use, a rod extending beneath the seat member and connecting the front pair of legs, -means affording a bin ed connection between the seat and bacr members and having means extending therefrom for engagin said rod.

4. A collapsible chair, com rising a rear pair of legs, a front pair 0 legs pivoted thereto between the ends thereof and extending above the upper end of said rear pair of legs, a seat member pivoted to the upper end of the rear pair of legs, a back member pivoted to the upper end of the front pair of legs and beyond the bottom edge 0 which back member the rear of the aerator seat member projects, a rod extending beneath the seat member and connecting the front pair of legs, and arms between the seat and back member providing a hinged connection therebetween, and means associated with the chair seat for engaging the said rod. 1

a. A collapsible chair, comprising a rear pair of legs, a front pair of legs pivoted thereto between the ends thereof and extending above the upper end of said rear 7 pair of legs, a seat member pivoted to the upper end of the rear pair of legs, a back spaced rear legs, a front leg pivotally mounted to each of the rear legs and extending beyond the respective upper extremities of the last named legs, said leg structure being interconnected by rung means adapted to allow of folding the complementary members into closed or alignedposition and of unfolding the same into open or crossed position, stop means serving to limit the unfolding of said leg members, a back member pivotally mounted between said pair of front leg extensions, a seat member pivotally mounted between the upper ends of the pair of rear legs and pro ecting rearwardly beyond the lower end of the back, sup lemental support means associated with the ont legs serving to uphold the unfolded seat relative to said seat pivots, and hinged means disposed between said back and seat members adzzpted to cooperate with the saidmembers wh' e unfolding the chair to guide the rearward portion of the seat underneath the back member, whereby the former projects beyond the latter and constitutes a seat manipulating element for chair folding purposes.

7. In a folding chair comprising a pair of spaced rear legs, a front leg pivotally mounted to each of the rear legs and extending beyond the respective up er extremities of the last named legs, sal leg structure being interconnected by rung means adapted to allow of folding the complementary members into closed or aligned position and of unfolding the same into open or crossed position, stop means serving to limit the unfolding of said leg members, a back member pivotally mounted between said pair of front leg extensions, :1 seat member pivotally IOI) unfolding the chair to guide the rearward portion of the seat underneath the back member whereby the former projects beyond the latter and constitutes a. seat manipulating element for chair folding purposes which by the raising thereof serves to swing the unfolded back member into a reversed position with respect to the scat member, the

seat and back members in folded chair po-o sition being made to assume substantial alignment with 'the folded leg members whereupon. said manipulating seat portion projects somewhat beyond the adjacent back member to also serve for chain unfolding purposes.

8. In a folding chair comprising a pair of spaced rear legs, a front leg pivoted to each of the rear legs and extending beyond .the respective upper extremities of the last named legs, said leg, structures being interconnected by rung means adapted to allow of folding said complementary members into closed or aligned position and of unfolding the same into openor cross position, stop means serving to limit the unfolding of said members, a back member pivotally mounted between said pair of front leg extensions, a seat member pivotally mounted between the upper ends of the pair of rear legs which pivots are adjoined to the front portion of the unfolded seat, supplemental support means associated with the front legs serving to uphold the rear portion of the unfolded seat relative to said seat pivots, and hinged means disposed between said back and seat vmembers adapted to cooperate with said members while unfolding the chair to guide the rearward portion of the seat into engagement with said support means and adapted while closing the chair to swing the back member about its front leg extension pivots for reversibly folding the back member upon the seat member and bring them into substantial alignment with-the closed leg members, the outermost seat element being disposed to project beyond said adjacent back member to constitute an unobstructed manipulating means for chair opening purposes.
