folding chairs and one of the objects of the same is to provide an improved. foldable chair which will be comparatively light and of metallic construction in which there will be no projecting bolts, screws, or fastening devices, especially about and around the seat, on which the clothing of the occupant might catch or snag. V

A further object is to provide an improved chair of this character which is adapted to the foldable parts being adapted when folded to stand substantially within the plane of the edges of the uprights or supports, so that the folded chair will lie flat, and

compactly arranged for 'the'purpose of storage or transportation.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially'the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying tion; and in which, I

Figure 1 is a perspective view of a chair constructed in accordance with the principles of this invention and showing the "parts in unfolded positions ready for use. Figure 2 is a view of the chair taken from one side thereof. 1

Figure 3 is a view similar to Figure 2 taken from the other side.

and partly in section of one end of the seat frame with the seat therein.

' Figure 10 is a detail perspective view of a portion of the seat frame showing the manner of inserting the seat therein.

Referring more particularly to the drawings the numerals 10 and 11 designate respectively two pairs of legs or supports which are pivotally connected together as at 12 intermediate the extremities of each. The'legs 10 extend upwardly for a considerable distance-to form standards 13, which are preferably connected together by their upper extremities as at 14:, and a back member 15is supported therebetween.

The legs 10 and 11 together with the standards 13 are formed of metal, preferably substantially I shape in cross section, the portions 16 of the metal being tubular.

A- substantially U shaped seat frame 17, preferably constructed of angle iron is pivotally supported adjacent one end thereof as at 18 intermediate the standards 13 preferably so that the open portion'of the framewill be disposed at the rear. of the seat. I

Pivotally connected adjacent the forward edge of the seat framey17. as at 19, isa bar or rod like member 20 which is adapted to telescope into the extremity of the tubular portion at the upper extremity of the the these bars or rods 20 being provided on each side of the seat frame.

The legs 11 may be braced if desired by means of a cross member 21, and if desired suitable feet or cushioning members 22 may be provided on the lower extremities of the legs.

The back member 15 is so arranged that it will not interfere with the folding movement of the seat frame 17.

With a chair of this character, it will be will swing about the pivots 18, at the same time the legs 11 will swing about the pivots When the seat frame 17 is pivoted away from the standards 13, the rods 20 will have teleleg 11, 6

:manifest that when the seat frame 17 is v folded with respect to the standards 13, it

scoping movements into the upper extremities of the rear legs and thereby cause the opening of the rear legs.

All of the parts above described are of such a size that when the seat frame 17 is folded, as shown in Figures 2 and 3, the seat frame and the legs 11- will'be disposed substantially within the planeof the edges of the standards 13. and legs 10, as shown more clearlyin Figure'6, so that a plurality of'these chairs when folded may be compactly arranged for storage or shipment purposes.

If desired a cap or ferrule 23 may be provided on the upper ends. of thelegs .11,,a-nd through which ferrule or cap the rod 20 passes.

A seat member 24 preferably having a base 25 is provided, and the edges of the base 25 project beyond the edges of the seat or cushion and these edges are adapted to enter inwardly opening channels formed by an inwardly projecting flange 26 carriedby the walls of the seat frame which co-operates with the upper edgeof the seat frame. i

The seat frame 17 may be formed of a single piece of metal bent into shape to form an angle iron construction, and also to form a flange 26' (see Figure 10) whichco-operates with the upper edge or flange 27 of the seat frame 17.

Any suitable means may be provided for maintaining the seat within the frame, such for instance, as a member 28, which is adapted to be extended across the open end of the seat frame and which member may be secured in position by means'of suitable fastening devices passing therethrough. I

If desired a pad or cushion30 may be provided on the back member 15 and which pad or cushion is preferably of a thickness to be substantially flush with the front edges of the uprights or standards lS.

lVith this invention it will bemanifest that a very light but strong'and durable chair may be produced, which may be readily folded and unfoldedand whichwill lie flat upon a'supporting surface when the parts are folded.
