2' Claims.

This invention relates to folding chairs which are mainlyuseful where portability is a strong consideration as in beach, camp or lawn furniture. While rigid frame seats have been affixed to such collapsible chairs, the present invention provides a novel and useful method of strongly fastening the front of the above-mentioned seat to the supporting frame. Other novel features of this invention are also present in the light but sturdy canopy frame and in the curved foot rest.

Still other features and advantages of the invention will appear more fully in the annexed detailed description and the appended claims.

In the drawing,

Fig. 1 is a front elevation of a folding chair embodying the invention.

Fig. 2 is an elevation in cross section approximately on lines 22 of Fig. 1.

Fig. 3 is a plan view of the stamping.

Fig. l is a sectional View of Fig. 3 on lines 4-4..

Fig. 5 is a fragmentary view showing connection between the canopy frame and the chair.

Fig. 6 shows the attached foot rest in section.

Referring to the drawing, members M and N are the chair legs which are pivotally connected at O. Legs M extend upward a sufficient distance to form the frame of the chair back. Legs N extend backward a distance sufiicient to provide stability to the chair when the frame H hinged at U to the chair back frame has its cross dowel J in one of the sets of the recesses in the legs N. Each set of recesses in the legs 1 N represents a different position of adjustment for frame H and thereby the chair. Comfortable arm supports are provided in this chair by arm rests S and supports T, hinged and pivoted, as clearly shown in Fig. 2, so as to come into the j plane of the collapsible chair when it is folded.

A flexible back A of any suitable material such as canvas, has upper end doubled around the cross dowel W set in the upper end portions of frame members M. This back passes over and rests againsta yielding transverse strip F of like flexible material which is fastened to the frame members M above wooden frame seat 0. This transverse strip comes about at the waist and helps support the back in a comfort- 50 able position.

The front of the seat C rests upon a cross dowel D fixed in the upper extension of legs N forming a front frame. For hinging the seat frame C to the dowel D, two metal stampings E are fastened, as by rivets, to the bottom of the two sides of the frame of seat Cin the manner shown (Figs, 1 and 2). The semi-cylindrical portion of each stamping fits over the dowel D. By these means the seat, padded if desired, now has a rotary motion relative to the dowel D. The slot L in the circular portion of stamping E permits the insertion of a centering peg P in the dowel D to limit the rotary movement of the seat and to prevent mis-alinement of the seat due to transverse creep. 5

A pillow B is made integral with the flexible back A in such a manner that when its use is not desiredit may simply be thrown over the back to hang down in the position shown by dotted lines in Fig. 2.

A simple rectangular canopy frame is connected to the top of the chair by links 11 and 12. Wing nut bolts 13 are mounted in the upper ends of legs N. These bolts 13 also pass through the lower ends of links 12. The other ends of links 12 are loosely riveted to frame 10. Links 11 are also swingably mounted in frame 10 andare arranged so as to allow their lower ends to be snapped into any set of holes 14 to obtain any'desired adjustment of the canopy. .When rods 11 are disengaged from holes 14, the canopy falls forward to make a most compact fold'with the backof the chair.

To fold the chair, dowel J is disengaged from the recesses in legs N, then arms H and the 1.

longer parts of the legs Nare swung upward until substantially in' line with legs M. By this same action the arms S and supports T and the seat C are brought in line with the legs M. The seat .0 is prevented from any 9' tendency to swing about its hinge away from the plane of the folded chair by abutment of the ends of the slots L with centering pins P. Again, these pins hold the seat in proper position laterally to enable afoot rest to be connected to the chair without any jamming due to the mis-alinementof the seat.

This foot rest is hooked on dowel D by means of plates 15. Nearer the chair side of the foot rest frame 16, there is located another .dowel 17. Slats 18, held at the ends by groove pieces 19, are sprung over dowel 17. In this way the top of the foot rest presents a curved surface which hasbeen found to make the chair as a whole more comfortable. In addition, dowel 17 strengthens the construction of the foot rest. When it is desired to take the foot rest off, legs 20 are merely folded into the plane of the frame 16.

By my invention the art is enriched by improvements which make afolding chair cheaper to construct, less cumbersome, lighter in weight and simpler in principle inasmuch as the frame of the chair embodying my invention is also adaptable to be used with a single flexible back and seat such as are used in common beach chairs.

What I- claim as new is:

1. In a chair of the character described, comprising front and back legs in pivotal connection, said legs extending'upward sufficiently to provide back and front frames respectively, a third frame pivotally connected to the back frame and engaging with the back legs to support the chair in set-up position, cross-members near'the tops of said back and front frames, a flexible back dependingfrom the rear crossmember, a seat with a rigid frame said seat supported in the back by said flexible back andin the front on the front cross-member, a transverse yielding strip fastened to said back frame and passing behind said flexible back, a pendant pillow integral with said flexible back, and slotted means locking the front of said seat and said front cross-member in limited pivotal relation.

2. In a collapsible chair, front and back legs in pivotal relationship, upward extensions of said legs providing a back frame and a front frame respectively, adjusting recesses in the back legs, a chair-supporting frame pivoted to
