FOLDING CHAIR.

Application filed September 9, 1926. Serial No.v 134,553.

The present invention relates to chairs,and more particularly to folding chairs.

One of the objects of the present invention is to provide'a chair which can be changed readily and quickly from occupantsupporting position to a compact folded position. I-n carrying out this object it is a further` ob}ect to arrange the elements of the chair 1n such a manner that -when the seat of the chair is moved from occupant-supporting position to its folded position, all of the other elements of the chair are moved to their folded position. And vice versa,v when the seat is moved from folded to occupant-supporting position, all of the other elements are moved to occupant-V y supporting position.

A still further object is to simplify the construction and facilities, andreduce the Acost of manufacture of chair seats. present invention, a channel iron isbent to the shape of a U and a seat portion 1s inserted between the flanges of the channel iron.

Another object is to provide a common means for securing'the seat portion to 1ts frame and for providing a back member for the purpose of maintaining the chair-in occupant-supporting position.

Other and further objects will be apparent from the following description, reference being had to the accompany-ing drawlng 1n which preferred forms of embodiment are shown.

In the drawings:

Figs. 1 and 2 are side and front views, respectively, of the improved chair showing same in occupant-supporting position;

Fig. 3 is a longitudinal sectional View of the chair showing the position that elements of the chair attain .while being folded;

Figs.-4 and 5 are side and front views, respectively, showing the chair in folded position; l

Fig. 6 is a sectional view taken on line 6--6 of Fig. 1;

Fig. 7 is a fragmentary view of the chair in occupant-supporting position, showing a certain modification; and

Fig. 8 is a view of the modified form shown in Fig. 7, but showing the chair being folded.

Referring to the drawings,v there is shown a main frame 10 comprising channel iron 11 which provides

uprights

12 and 13 and ank upper arcuate-shaped connection 14. The

uprights

12 and 13 form the front legs of the'chair and are connected atthe bottom by In the a brace 15." A brace 16, which may be used as a footrest, is connected between the

uprights

12 and 13. Another brace 17 is connected between said uprights substantially midway between the top and bottom of frame on which a seat 19 is adapted to rest, Braces 15, 16 and 17 are secured to the uprights-in any suitable manner, as by bolts or rivets 20.

A slightly concaved back-rest 21 which is ,also formed to the contour of the arcuateshaped connection 14 is suitably secured, as by welding or bracing, to said connection.

A secondframe 23 is provided and comprlses a U-shaped

iron providing uprights

24 and 25 and a'bottom portion 26. The

uprights

24 and 25 provide the rear legs of the chair." The upper portion of uprights`24 and 25 are bent outwardly, as at 27, and the upper ends thereof are pivotallyl connected by bolts or

sc'rews 28with uprights

12 and 13, respectively.

Seat 19 comprises a U-shaped channel iron 29 and a seat portion 30 of wood or the like. If desirable, the top of portion 30. The seat portion 30 is formed to the contour of inner portion of the base 32 ofchannel iron 29 and vis inserted vbetween the flanges 33 of the channel iron 29.

The rear ends of the channel iron carry bolts v37 by which said seat is pivotally secured to the

uprights

24 and 25. Bolts'37 extend through slotted links 39, which are a padding 31 may be placed 0n pivotally secured, as by bolts 40, to uprights 12 and 13. Links 39 serve to limit the rear- Ward movement of frame 23. It will be noted that the

uprights

24 and 25 are spaced a substantial distance from the

uprights

12 and 13 adjacent links 39, so that the links may fold between said uprights. When the chair is in occupant-supporting position, the seat -19 ,restsupon brace 17 and the cleats 35 are located directly in back of the brace 17. With the cleats 35 in back of the brace 17, the legs of the chair will not collapse unless the seat 19 is lifted. AThus the cleats form a back for the chair and the chair will remain innocention, a main frame providing leg means, aV

.slid about.

One of the advantages of the present .invention is that the chair can be readily changed from occupant-supporting position to a compact foldedposition. It is necessary only to move the seat from one position to the other in order to fold the entire chair. As the seat is lifted, a portion intermediate the front and back thereof will engage the backrest 21, as indicated at 41`in Fig. 3. Then, by continuing movement of the seat 19 toward the collapsed position, said seat will fulcrum about point 41 to cause the lower end of said seat to move to a position within the outer side planes or confines of the frame 10, and, since the links 39 and the frame 33 are connected with the seat 1 9 by bolts 37, said links and frame will telescope with the frame and move to position parallel with frame 10,

Likewise, the chair can be changedreadily from its folded to its occupant-supporting position. By swinging the seat downwardly and then forcing same rearwardly, the frame 23 will be' moved rearwardlyto provide the n rear legs of the chair.

' In Figs. 7 and Sanotherjform of link is disclosed. In this modification, one end of a link member 39 is. pivotallyconnected with one end of a link member 39b and the other ends of said link member are connected, respectively, with

uprights

12 and 24.
