FOLDING CHAIR.

Application filed October 15, 1927. Serial No. 226,277.

The present invention relates to chairs and particularly folding chairs. One of the objects of the present invention is to provide an improvement in chairs of the folding type which chairs can be folded or unfolded quickly and which when folded are compact and can be readily stacked on one another.

Another ob e'ct is to improve the construction of folding chairs, to provide a rigid chair, and to facilitate the manufacture andthus reduce the cost thereof. 7 Y

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanyingdrawing, wherein a preferred form of the present invention is clearly shown.

In the drawings: I I

Fig. 1 is a side view of my improved chair;

Fig. 2 is a front view of the chair;

Fig. 3 is a side view showing the chair partly folded;

Fig. 4 is a side view showing same completely folded V Fig. 5 is a fragmentary perspective view of a'portion of the chair;

Fig. 6 is a sectional view taken of line 66 of Fig. 1; r

Fig. 7 is-a fragmentary rear view of a portion ofthe chair, and I n Fig. 8 is "a sectional view taken on line 8-8 of Fig. 7. 1

Referring to the drawings, the chair comprises a main frame 20 formed of channeliron and constitutedupright-s 21 and 22 and provides an upper arcuate-shaped connecting portion 23. Uprights 21 and 22 provide front legs for the chair. A brace 25 connects the bottom ends of

uprights

21 and 22 and a brace 26 is connected with the uprights which latte-r brace may be used as a foot rest. Another brace 27 connects the uprights substantially midway between'the top and bottom of said uprights and upon which a seat 29 is adapted to rest. A slightly concaved backrest 30, having its ends formed to'the contour of the arcuate-shaped uprights, is suitably secured to said uprights. V I

' A second frame 31 which is U-shaped provides

uprights

32 and 33 and a bottom portion otal connection forthe seat 29.

34. The upper ends of the upright-s 32 and 33 areipivotally connected, respectively, to uprights 21 and 22 and constitute the rear legs of the chair.

The seat 29 includes a U-shaped channel ronStS and a seat portion 37. The portion 37 is formed to the contour of the base 38 of the channel iron and is inserted between-the flanges 4001 said iron. If desired, a covered, padding 42 may be placed on the top ofthe seat portion 37. The seat portion 37 terminatesshort of the iron 36 and a bolt43'extends through said ends. threaded on the bolt, which nuts when tightened draw the ends ofthe iron 36 toward one another to hold the seat portion firmly in place. The ends of bolt 43 extend through the

rear uprights

32 and 33 to provide a pivT threaded on the bolt 43 for holding the uprights 32 and-33 in place and-these nuts are locked in position in any suitable manner, as for example, by. riveting over the ends of the holt43.

U-shaped connectingmembers. 47 each have one leg 48 thereof suitably secured as by weld- Nuts 44 are Nuts 45 are ing, to the chair iron 36 on opposite sides of the seat 29. The other legs 49 are each pivotally connccted'with links-50. The opposite ends of links 50 are pivotally connected at 51 to the uprights 21 and22.

.lVhen it is desirable to foldthe chair, the seat29 is moved upwardly, and due to the location of U-shaped connecting members 47 I and links 50 with respect to the seat and uprights, the rear frame 31 will be pulled forwardly and when the upper part of chair seat is foldedagainst the back rest 30, the rear frame31 will be folding within the front frame 20. The recesses between the.

legs

48 and 49 of members 47 will receive the uprights 32 and the links 50 will be disposed between the

uprights

32 and 21 on one side of the chair, as clearly shown in Figs. 7 and 8. It is to be understood that the link 50-011 the opposite side of the chair will fold between

uprights

33 and 22. Thus it is apparent that the entire chair will telescope to provide a narrow structure when folded. The chair can also be changedfrom folded to occupant-s11pporting position as readily as it can be folded. In order to has been provided which can be folded and unfolded quickly and When folded occupies only a small space and a plurality ofthese folded chairs can be stacked readily. The links 50 and the connections therefor are all disposed below the upper part of the and in such position that no protuberances are presented which may catch the clothing of the person occupying the chair,

The structure of the seat and the manner of assembling same provides a novel feature. After the seat portion is inserted between the flanges of the channel iron, it is held in place by the bolt which provides a pivotal connec- "tion between the seat and the chair frame. When the nuts A l are drawn the substantially parallel portions of the iron 36 firmly engage'the-side edges of seat portion 37 while the bolt 43 lies adjacent the back edge of the portion 37 to prevent said portion from-movin-g out of position in the event that the nuts 44 become'loose.

While the form of embodiment of the invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms mightbe adopted, all coming within the scope of the claims which follow.
