FOLDING CHAIR.

Specification of Letters Patent.

Patented Mar. 5, 1918.

Application filed November 1, 1916. Serial No. 128,818.

To all whom it may concern:

Be it known that I, JAROSLAV PREMYSL, a citizen of the United States, residing at the city of Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Fold ng Chairs, of wh ch the following is a specification.

My invention relates to improvements in folding chairs, and it pertains, more especially, among other things, to the peculiar construction of the back and other cooperating parts of the chair, whereby such parts are adapted to be folded both downwardly and from its respective sides as well as from the front and rear, whereby when such parts are folded together they are adapted to occupy the least possible space, and whereby the same may be conveniently carried by a person to a place of use.

My invention is further explained by reference to the accompanying drawing, in which- Figure 1 is a front view, and I Fig. 2 is a side view of my chair in position for use.

Fig. 3 represents the chair with the back in its folded position.

Fig. 4 is a side view, drawn on line 4, i of Fig. 1, partially folded.

Fig. 5 is a front view of the chair as the same appears in its folded position.

Fig. 6 is a side view of the chair in its folded position, the lower portion being broken away, and

Pi g. 7 is a bottom view of one of the seat supporting bars formed of two separate pieces which are hinged together at their ends. drawn on line 7, 7 of Fig. 2.

Like parts are identified by the same reference numerals throughout the several views.

1 is a seat which is formed of canvas or other similar material, and the same is secured at one end to the front bar 2, and at its opposite end to the rear bar 3 by a plurality of tacks 4. The bars 2 and 8 are each formed of two members 5, 5 and 6, 6 which members are connected together by the hinges 7. Said members 5, 5 and 6, 6 are pivotally connected at their outer upper ends to the legs 9, 9 and 8, 8 by the pivotal bolt 10, whereby said members 5, 5 and 6, 6 are adapted to be turned down, as shown in Figs. 5 and 6, thereby' permitting the le 8, 8 and 9, 9 to be rought toward eac other. The lower ends of the legs 8, 8 are connected with each other by the brace members 12, 12, and'the lower ends of the rear legs 9 are connected together by the brace members 13, 13, and said brace members are connected together centrally between said legs by the pivotal bolts 14, vsaid braces being respectively connected with the front and rear legs in like manner by the pivotal bolts 14.

The top cross bar 15 is Pivotally connected at one of its ends to the side arm 16 by a pivotal bolt 17, and said bar 15 is adapted to be connected at its opposite end to the other side arm 18 by a metallic bracket 19, and it is held in place in said-bracket 19 by the retaining member 20, said member 20 being revolubly connected at one end with said side arm 18, and being adapted to be turned so that its opposite end is brought above said member 15. wherebv the latter is retained in place, as shown in Fig. 1. The side bars 16 and 18 are adapted to be pivotally connected at their lower ends to the rear upper ends of the legs 8 by the pivotal bolts '21, while they are adapted to bear at their rear sides against the opposing sides of the bars 3, as shown in-Fig's. 1 and 2.

The front and rear legs 8 and 9- are pivotally connected together near their centers by the bolts 22. Thus. it is obvious'that when it is desired to fold the chair one end of the cross bar 15 is first disengaged from the bracket 19 and its free end is turned over on its pivotal bolt 17, whereby said bar is brought to near the vertical position, as indicated by dotted lines in Fig. 1. When this is done said side arms 16 and 18 are both turned forwardly on their pivotal bolts 21 until they are brought substantially parallel to the legs 8. 8. When this is done the" brace members 12 and 13 are turned upwardly to the position shown in Fig. 5, and

. the front and rear seat supporting bars 2 and 3 are inclined downwardly, as in Figs. 5 and 6, whereby all of said parts are folded together in a compact form for either storing or shipping.

The brace members,12 and 13 are each preferably provided with a projecting hearing 25 which is adapted to seat in a recess 26 formed in the opposing brace member, whereby said brace members are prevented from being turned downwardly when tits;

are folded together, as shown in Fig. 5. is an umbrella, which is pivotally. supported from the bar 15' on the pivotal bolt 28 and the lower endof the 29; is'connected shown I claim as new and desire to with the side arm 16 by the pivotal bolt 29', notched bar 30 and bolt 31, whereby said umbrella is adapted to be inclined toward the right or left and secured at difierent points of adjustment corresponding with the distance between the notches 32, which notches are formed for the reception of said bolt 31.

It will, of course, be understood that the pivotal bolt 28 and the staff 29, together with the umbrella and notched plate 30, are withdrawn from the chair preparatory to folding the same.

Having thus described my invention what secure by Letters Patent, is

The combination of the respective side eas es bars of the back of a chair, crossed legs, a pair of horizontal seat supporting bars, each bar formed of two members, a pair of hinges connecting the ends of said horizontal bars, two pairs of bolts connecting the outer ends of said horizontal bars with the upper ends of said legs, and a pair of bolts for connecting said legs near their centers, all substantially as and for the purpose specified.

In testimony whereof I affix my signature in the presence of two witnesses.

JAROSLAV PREMYSL.
