Referring in detail to the drawings, the numeral 33 designates a vertically disposed, side frame member which may be fabricated of any suitable material, such as tubular metal. There are a pair of the side frame members 3U, and since each has the same construction, only one will be described in detail. Each of the side frame members 3U comprises a lower web 3|, Figure l, and the web 3| has an arcuate shape so that when the user is supported by or seated in the chair, the user will be able to rock himself or herself back and forth to thereby provide a comfortable rocking chair. The side frame member 30 further includes a substantially vertically disposed leg 32 which is formed integrally with or extends upwardly from the front end of the web 3|, and the rear portion of the web 3| is shaped to define a stop member 33, Figures 1 and 4. The stop member 33 will engage with the floor, as shown in Figure 4, in the event that the chair is rocking backwardly too much, so as to prevent the chair and occupant thereof from being tilted or toppled over backwards. The stop member -33 has its upper end terminating in a substantially vertically disposed standard or upright 34, while the upper end of the leg 32 terminates in a horizontally disposed arm rest 35. The arm rest 35 has its free end secured to the standard 34 in any suitable manner. The side frame members 30 are, or can be, moved toward each other, as shown in Figure 3, when the chair is not being used, so that the chair can be folded to occupy a minimum amount of space when it is to be stored or shipped. A

' Extending between the standards 34 and secured thereto is a flexible back rest 36, Figure 14. The back rest 36 may be fabricated of any sluitable flexible material, such ran canvas, and end portions 31 of the back rest 36 are Wrapped around `the standards 34 'and a suitable line of stitching 38 serves to secure the end portions 31 to the main portion of the 'back rest 36. Thus, the back rest 36 is permanently connected to the standards 34.Y Arranged over the back rest 36 is a cover 39, Figure 15. The cover 39 is hollow and is made of a suitable fabric. The cover 39 is highly attractive, and the cover 39 is so shaped or constructed that it can be readily lifted onto or off of the back rest 36. As shown in Figure 15, the cover 39 is provided with snap fasteners 40 and receivers 4|, and the snap fasteners 40 and receivers 4| are adapted to be arranged in engagement with each other when the cover 39 is mounted on the back rest 36, so as to prevent the cover 39 from accidentally working loose from the back rest 36.

Arranged contiguous to the inner surface of each of the side frame members 30, and mounted 4 a washer 59 arranged between each pair of braces 51, Figure 12, and a nut 60 is arranged in threaded engagement with each of the bolts 58 for maintaining the parts in assembled relation. Suitable continuous rubber or resilient bands or members 6|, Figure 13, are trained over the upper ends ofthe braces 51 and are also arranged in engagement with the legs 32, the rubber band 6| serving to help maintain the seat in its proper relation.

The hinge means for connecting the lower ends of the braces 51 to the web 3| is shown in detail for sliding movement therealong is a horizontally disposed crossbar 42, Figures 8 and 9. The crossbars 42 are hollow, and end pieces 43, Figure 2, serve to close the open ends of the crossbars 42. Extending between the pair of crossbars 42 is a flexible seat member 44, the seat member 44 being fabricated of any suitable material, such as canvas. For securing the ends of the seat member 44 to the crossbars 42, a plurality of suitable securing elements, such as bolts or screws 45, extend through a folded portion of the seat member 44, Figure 9, and into threaded engagement with the crossbars 42. A reinforcing strip 46 is interposed between the folds of the canvas seat 44. A suitable seat cover 41 is extended over or arranged over the seat member 44, and the seat cover 41 may be fabricated of any suitable attractive material. The seat cover 41 is detachably connected to the crossbars 42 by means of snap fasteners and receivers 48 and 49, the snap fasteners 48 being arranged along the bottom of the crossbars 42, while the receivers 49 are secured along the edges of the seat cover 41. By arranging the receivers 49 in engagementl with the snap fasteners 48, the seat cover 41 can be detachably connected across the seat member 44, so that the seat cover 41 will not accidentally work loose.

Resilient support members 50, Figures and l1, are provided for supporting the crossbars 42 when the chair is in extended position and when the chair is occupied, so that the support members 59 have suicient resiilency to enable the occupant of the chair to be supported in great comfort. Each of the support members 50 includes a horizontally disposed angle iron5| which extends between the standards 34 and the legs 32, and the angle iron 5| is secured to these last- -named members by suitable bolt-and-nut assemblies 52. A rubberbumper 54 is supported by the angle iron 5|, and a suitable rubber casing or cover 53 encloses or surrounds the rubber bumper 54, the casings 53 and'54 being maintained in their proper positions on the angle iron 5| by means of bolt-and-nut assemblies 56 which extend through theangle iron 5| and througha retaining strip 55. When -the chair is in extended position and when a person is seated on the member 44, the crossbars 42 will be in the position shown in Figure 2, so that the crossbars 42 will be resting upon the support members 50, whereby a person will be able to sit with comfort.

Suitable braces 51 are provided, and the braces 51 are arranged in pairs in criss-cross relation, the braces 51 having their lower ends operatively or hingedly connected to the web 3|, While the upper ends of the braces 51 are secured to the crossbars 42. As previously stated, the braces 51 are arranged in pairs, and these pairs of braces 51 are pivotally connected together by a bolt 5 8. The bolt 58 extends through suitable registering apertures in the pairs of braces 51, there being in Figures 5, 6 and 7. This hinge means comvprises'a bushing 62 which is arranged in the web 3|, and the bushing 62 is secured in place in the web by means of a suitable screw 63. Projecting from the bushing 62 or formed integrally therewith is an apertured ear 64, Figure 6. Arranged in the lower end of each of the braces 51 is a plug or stop piece 65, and the plug 65 is bifurcated or provided with a slot 66 for slidably receiving therein the apertured ear 64. The plug 65 is secured in the brace 51 by a suitable screw 61, and a pivot pin 68 serves to pivotally connect the plug 65 to the apertured ear 64. Also, the lower portion of each of the braces 51 is cutaway, as at 69, so as to provide sufficient clearance for the ears 64 when the braces pivot. i

From the foregoing it is apparent that a folding or collapsible rocking chair has been provided which, when in the position shown in Figuresl A1 and 2, will provide an extremely comfortable rand attractive seat or rocking chair for a person. When the rocking chair is not being used, it can be readily folded to the position shown in Figure 3, and occupies a minimum amount of space. To fold or move the parts of the chair from the positions shown in Figures 1 and 2 to the position shown in Figure 3, it is only necessary to move the two frame members 30 toward each other and since the back rest and seat are made of flexible material, there will be no interference with this closing or collapsing of the chair. The arcuate portions of the webs 3| provide a rocking surface for the chair, and the stop member 33 serves to prevent the chair from accidentally toppling over backwards. Also, the back rest 36 provides a means for limiting opening movement of the side frame members 30 away from each other. Further, the chair of the present -invention includes the support members 50 which are resilient, so that there will be provided a comfortable support for the occupant of the chair. Further, the back rest cover 39 and the seat cover 41 can be conveniently arrangedv on the chair so as to protect the parts of the chair and also provide a highly attractive rocking chair. Also, the construction of the hinge shown in Figures 5, 6 and '1 enables the chair to be readily moved into and out of its operative position.
