This invention relates to chairs particularly .adapted for porch or other outdoor use whereby the usefulness of the chair will not become affected by climatic conditions, and it is the 5 principal object of the invention to provide such a chair of flexible structure which will readily assume the postures of different users. a Another object of the invention is to provide a foot or leg rest adapted to be releasably connected to the chair to extend as a continuation of the seat portion of the chair and when detached from the chair may be used as an independent seat or stool. v

A still further object of the invention is to provide a chair of resilient frame members adjustably connected, and a seat and integral back rest suspended by the frame members, said seat back and rest and the frame being adapted to adjust themselves to different supporting positions.

Further objects of the invention will hereinafter be set forth indetail.

The embodiment of the invention illustrated comprises a pair of resilient frame members each member having a leg portion looped to form prising slats engaged on the stringers in spaced,

relation to each other. The chair is provided with a foot rest comprising a resilient frame arranged to support a flexible and arched mat or supporting surface and having means to releasably engage the front or free end of the seat portion of the chair to connect the foot rest and chair together.

The boards I5. are maintained in spaced relation to each other by a spacerll engaged at the opposite ends on the bolts l6 superposed to the frame ends ii", the spacer and frame sections being secured to the boards-l5 by nuts l8 engaged onto the bolts II. The part of the supporting sections II, I: adjacent the loops Ill engage and are sup ported by the opposite end portions of the boards I! to permit of flexing movement of the frame sections l2, it toward and away from the opposite sections I I, I3 when weight is applied to the sections l2, M, the frame sections I I, I3 being slidably connected to the base boards bycleatsin the form of plates l9; secured to the boards by screws passed through perforations in the plates, as at 20, and the plates having ears 2| to engage about the edges and over said frame sections to loosely retain the frame members to the boards and permit of sliding movement of the frame members longitudinally of the boards, as clearly shown in Figure 1,

The arm supporting portions 22 of the frame members by and between which an integral seat and back rest is suspended and supported are of ogee form arranged intermediate their ends with a pair of holes to be superposed to a pair of a series of holes 23 in the curved portion I '4' of the leg portions whereby supporting portions 22 are adjustably connected to the leg portions in predetermined positions longitudinally of said leg portions by bolts 24' passed through the holes in the arm supporting portions in register with the desired pair of holes 23 in the leg curved portions l4 and secured by nuts threaded onto the bolts,and said supporting portions are thus capable of being mounted on the leg portions to extend in various angular positions relative to said leg portions, the ends of said portions extending forward of the connection and parallel with the leg portions and are adapted to serve as arm rests. The curvature of the intermediate sections of the arm supporting portions coincides with the curved portion l4 of the leg sections to assure an even and neat appearing connection. The ends of leg portions are beneath the arm supporting portions and the heads of the bolts 24' are rounded to present a' smooth surface and prevent injury to the arms or the tearing of the clothing of the user. The supporting portions 22 are connected in spaced relation by a pair of cross bars 24, 25, the bar 24 being fixed at the opposite ends to the uppermost ends of the portions 22 by bolts passed from the front through alined perforations in the members and nuts engaged thereon at the rear of the chair, as at 26 in Figure 5. The'other cross bar 25 is removably mounted on the lowermost ends of the frame portions 22 to be adjustably positioned longitudinally of said portions for a purpose hereinafter set forth by" providing a series of holes 21 in said ends of the portions 22 for the engagement of a bolt 28 passed from the front through a perforation in cross bar 25 and one of the holes 21 and retained in position by nuts threaded onto the bolts at the under surface of the portions 22.

The seat andback supporting member of the chair is of unitary structure and adapted to readily assume the posture of the body. The seat and back supporting member is suspended between the cross bars 24, 25 and comprises a plurality of flexible stringers 29, such as brass wire to prevent the destructive oxidation of the same by the atmosphere, and formed from a length of wire into U shape with the connecting P rtion 30 of a length to form pairs of parallel and adjacent stringers, as shown in Figure 6. The stringers are passed through pairs of perforations 3| extended through and adjacent each end of the cross bar 24, and drawn through the perforations 3| until the connecting portions 30 of the stringers abut the cross bar between the perforations. The stringers are of sufiicient length so that the free ends will extend through pairs of perforations 32 in the cross bar 25 with a sag in the stringers to permit them to assume an arcuate position between the'cross bars 24, 25. The stringers are secured in this suspended position between the cross bars by bending the free ends at right angles toward each other and over portions of the cross bars between each pair of perforations 32, as at 33. To'enhance the appearance of the chair the connecting portions 30 and the bent ends 33 of the stringers are concealed from view by recessing the bars at the outer entrance to and between the pairs of perforations 3|, 32, as at 34, said recesses being of a depth to position the stringers below the surface of the cross bars, as shown in Figures 4 and 8, and concealed by strips 35 secured to the outer sides of the cross bars, as by nailing.

The supporting surface of the seat and back rest comprises slats 36, preferably strips of wood, having pairs of perforations 31 transversely therethrough adjacent the ends of the slats to be engaged on the stringers, the slats being maintained in equidistant spaced relation to each other by tubular members 38 engaged on the stringers in interposed relation to the slats. In assembling the seat and back support the stringers are extended through the bar perforations 3| when the tubular members and the slats are strung onto the stringers and before the free ends of the stringers are engaged in the perforatio 32 of bar 25 by first engaging tubular members 38 thereon and then a slat 36 which procedure is successively performed until the necessary length of the seat and back support to be suspended between the cross bars is produced, as clearly shown in Figures 1, 2,- 4 and 5. The curvature of the seat and back support is adjustable to meet the requirement for different body supporting positions by engaging the bar securing bolts 28 in different openings 21, thus securing the crossbar 25 in different positions to the arm rest of the frame 22 and varying the length of theseat and back rest. The body supporting positions of the seat and back rest may be also varied as an entirety by adjusting the entire arm supporting frame portions 22 through the movingof said portions along the leg sections l4 and engaging the bolts 24' in different holes 23 in the leg sections l4.

The seat and back rest of the chair is of a length to support the body of the user at just above the knees, and to comfortably rest the entire body there is provided a foot rest releasably connected to the cross bar 25, whereby it may be utilized as a separate seat or stool. The foot .rest comprises a supporting frame embodying a pair of opposed U-shaped frame members of resilient material, the connecting portions of which extend in a fiat horizontal plane, as at 39 in Figure 2, with the leg portions 40 arranged of opposed ogee form, as clearly shown in Figures 2 and 9, whereby great resiliency is embodied in the frame members. The frame members are connected in spaced relation corresponding to the spacing of the frame members of the chair by supports 4| of fiat form secured, as by bolts '42, to the free ends of the leg portions 40. The

supporting surface of the foot rest or stool is resilient and comprises two pairs of resilient stringers, in the present instance brass wire, formed to U-shape and anchored to cross bars 43 in a manner similar to the connecting of the stringers 29 of the seat and back rest of the chair to the cross bars 24, 25, with a series of slats 44 mounted on the stringers alternately with and equidistantly spaced from each other by tubular members 45 engaged on the stringers alternately with the slats 44, similar to the arrangement of the slats 36 and tubular spacers 38 of the seat and back rest of the chair. The resilient leg supporting mat formed by the stringers, slats 44 and tubular members 45 extends in the form of an arch to permit the flexing of the same in a downward direction without abutting the connecting portions 33 of the frame members by mounting the cross bars 43 on the connecting portions 39 a distance apart less than the length of the stringers, as clearly shown in Figure 2,

chair there is provided a pair of hook shaped members formed from sheet metal having one end bent to U'shape, as at 45', and the opposite end 4! arranged to-arcuate shape to conform to the curvature of the juncture of the connecting portion 39 witha leg portion 40 of the frame members of the stool and having a perforation for the engagement and mounting on the bolts for securing the cross bars 43 to the frame members 39, the hook members being clamped between. the cross bar and the frame members. as shown in Figure 2. The U portions of the hook members are of a size to be readily engaged over the cross bar of the chair. It will be obvious that the stool may be utilized independent of the chair.

To reduce the cost of manufacture and when the foot rest is to be used with and as a unitary part of the chair, the supporting frame thereof is arranged with only one pair of legs 41. ex-

- tending from one end of the horizontal portions 39 in ogee form and connected at the ends by a 4 support similar to the supports 4!. The ends of the horizontal portions I! opposite to the legs 41 are connected to and supported by the cross bar 25 of the chair by extending said ends beyond the adjacent cross bar 43' of the leg supporting mat of the foot rest and forming the ends to U- shape, as shown at 48 in Figure 3, tobe readily engaged over the cross bar 2! of the chair.
