Application filed June 21,

This invention relates to improvements in chairs.

Une of the objects of the present invention is to provide an improved chairof simple and rigid construction and which may be readily folded up.

Another object is to provide an improved chair which is provided with detachable rocker elements whereby thcchair may be rgadily converted into a rocker or stationary 0 air.

Uther objects and advantages will hereinafter appear.

For the purpose of illustrating the invention, one embodiment thereof is shown in the drawings, in which,

Figure l is a side elevational view of the improved chair Fig. 2 is a front elevational view, looking toward the left in Fig. 1;

Fig. 3 is an enlarged fragmentary view, taken from 1;

Fig. i is a sectional view, taken on the line H in Fig. 3;

Fig. 5 is a view similar to Fig. 2, showing the improved chair partly folded; and

F ig. 6 is detail perspective view of one of the parts.

The improved chair comprises, in general, the side frames 10 and 11, the foldable stool 12 arranged therebetween and the rocker elements 13 and 14 attached to the legs of the side frames in the manner hereinafter explained.

The stool 12 comprises the two pair of crossed legs It and 16 pivotally connected intermediate their ends for folding one upon the other by means of rivets or other suitable means 17 and 18, respectively, and the flexible seat 19 of fabric material, the latter being connected in any suitable manner to the cross members 20 and 21 secured to the upper ends of legs 15 and 16.

The side frames 10 and 11 disposed on opposite sides of the foldable stool 12 are identical in construction and include the front vertical legs 22 and 23 to which the lower ends of the stool legs 15 are connected by means ofthe bolts or rivets 24 and 25. The side frames include, further, rear vertical legs 26 to which the lower ends of the stool legs 16 are pivotally connected by bolts or rivets 27. The frame legs 22 and 23 are made of flat metal strip and are bent back upon themselves at their respective lower 1926. Serial No. 112332.

ends, as shown, to form the eyelets 28 and 29, the rear legs 26 of these frames being also made of flat metal strip and bent back upon themselves at their respective lower ends to form similar eyelets 30.

In further regard to the side frame 10, the flat strip forming leg 22 is bent over at a right angle to the latter, as shown in Fig. l, to provide a horizontal arm portion 31, the strip then being bent abruptly upwardly to provide the upstanding portion bent back upon itself at the upper end form the eyelet The flat strip forming the rear leg 26 of frame 10 is continued upwardly and bent rearwardly at slight angle, as shown provide the upsta:.- ding portion 3% arranged parall l to pbrtion A reenforcing strip is interposed between and secured to portions and 3%, well as to the leg 26 at the point 36, by any suitable means such as electric welding. An arm rest 37 may be secured to the horizontal portion 33. by means of rivets 38.

For the purpose of reenforcing side frame 10, a triangularshaped frame 39, made of a single piece of flat metal strip with the ends d0 thereof abutting at ll, may be arranged as shown in ig, l and electrically welded at 42 to leg 22 and to the lower end of the reenforcing strip or portion 35. An inverted ll-shaped brace of fiat metal strip is arranged as shown with its high portion 45 electrically weld-ed to the abutting ends 4-0 of frame 39, the ends 41; of the brace being electrically welded to the lower ends of legs 2.2 and 26. A horizontal bracing member 4:? may be arranged as shownwith its ends 48 bent downwardly and electrically welded to ends 46. The side frame 11 being identical in construction to side frame 10 just described in detail, no detail showing and description of frame 11 is deemed to be necessary.

-The rocker element 13 is made of angle iron and is L-shape in cross section, and comprises the base 49 and the upstanding flange 50 provided with openings for receiving the bolts 51 and 52 for the purpose hereinafter explained. L-shape brackets 53 are arranged as shown in Fig. l, and secured to base 49 in any suitable manner such as by electric welding, those brackets being provided with upstanding lugs 54: provided with apertures 55 registering with the openings in flange 50 to also receive bolts 51 and 52. As more clearly shown in Figs. 3 and 4, the lower ends of the frame legs 22 and 26 seat on brackets 53 and are disposed between flange 50 of the rocker element and lugs 54 of brackets 53, the eyelets 28 and 30 registering with the openings or. apertures in flange 50 and lugs 54 for receiving bolts 51 and 52, whereby the latter provide means for holding legs 22 and 26 and rocker element 13 in assembled relation, removal of bolts 51 and 52 and their associated nuts 56 permitting of ready removal of'the rocker element 13, the eyelets 28 and 30 then engaging the ground or floor and providing casters for the chair.

The rocker element 14 is identical in construction to rocker element 13 just described and is secured by means of the bolts 57 to the lower ends of legs 23 and 26 of side frame 11 in the same manner as rocker element 13 is secured to the respective lower ends of legs 22 and 26 of the side frame 10.

A piece of fabric material 58 may be secured at one end to the portions 32, 34 and 35 of side frame 10 and at its other end to the corresponding portions of side frame 11, as shown to provide a back rest, the

piece .58 being arranged to become taut simultaneously with the seat 19 of the foldable-stool 12.

From the foregoing it will be apparent that upon spreading or movement of the side frames 10 and 11 away from each other the stool 12 interposed between the latter and connected thereto in the manner described will unfold, as shown in Fig. 2, further spreading of the side frames being prevented when seat 19 and the back iece 58' become taut. In folding up the 0 air, the side frames 10 and 11 are moved toward each other, as shown in Fig. 5, this movement of the side frames together being accompanied by folding of the stool 12 between the latter. In Fig. 5 the chair is shown as partly folded, but it will be understood that the side frames 10 and. 11 are ,moved as close together as possible to cause complete folding of stool 12 with its legs 15 and 16 folded one upon the other.

For the purpose of preventing spreading of side frames 10 and 11 when the chair is unfolded and in use, links 57 are arranged as shown and pivotally connected by means of bolts or.rivets 58 to the front frame legs 22 and 23, the inner ends of these links being provided with slots 59 receiving pins 60 fixed in the stool legs 15 at points above their pivotal connection 17. Similar links 61 are pivotally connected to the rear frame legs 26 by the rivets or bolts 62, with their inner slotted ends connected to the stool legs 16 by pins 63 similar to pins 60..

The arrangement is such that when the chair is unfolded, as shown in Fig. 2, pins 60 engage the outer ends of slots 59 to preagainst the frame legs 22, 23 and 26, the

pins 60 and 62 fixed in the stool legs sliding along the slots in the outer ends of the links to permit of this action, the pin-andslot connections compensating for any slight irregularities in the chair parts and permitting of movement of the side frames close together and complete folding of stool 12 therebetween.

From the foregoing it will be seen that an improved chair has been provided which is simple and rigid in construction, which may be readily folded and unfolded, and which may beconverted from a rocker to a sta tionery chair, or vice versa.

One embodiment of the invention has been shown and described, but of course various changes may be made in the slze, shape and arrangement of the parts without departing from the spirit of the invention or the scope of the claims.

The invention claimed is:
