FOLDING oH In.

This invention relates to an improved construction of foldingzchair, more particularly of the type having a foot rest attached to the forward edge of its seat portion; and the object of this invention is to provide a construction by which the foot rest may be pivotally attached to the seat portion in such a manner as to prevent the same from being easily broken. I I

A further object of the invention" is to extend the side rails of the seat portion of the chair and topivot the foot rest to the extending portion of these side rails to enable the same to have a greater swing relative to the seat portion and'to provide a stronger pivot or hinge construction and one less liable to be broken. 7

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a perspective view of a socalled steamer chair with the foot-rest portion attached thereto and in extended position.

Figure 2 is a View partly in section show- I ing the foot rest member pivotally connected to the seat portion of the chair.

Figure 3 is a sectional detail side elevation showing the relation of the extended side rail of the seat and a portion of the foot rest in extended or working position.

Figure 4 is a view similar to Figure 3 showing a portion of thefoot rest folded beneath the seat.

Figure 5 is a view similar to Figures 3 and 4: illustrating the foot rest as being swung in the opposite direction and as being raised at an angle to the seat. I

Figure 6 is a detail in section showing a slight modification in which thepivot pin, which connects the foot rest to the seat portion, extends complete through the meet ing cross bar of the foot rest.

It has been customary in attaching a foot rest to the front edge of the seat of a folding chair, to use metal hinges by which construction the foot rest could be folded under hinges due to the long leverage of the rest that would in time'result in tearing the 192s, seal to. 124,638.

hinges from. position. Such a strain is frequently caused by personsfunaccustomed to the use of the chair in attempting to fold thesame. y

In order to obviate this diflicultyand pro vide a strong and durable construction that cannot be broken by swinging the rest upward, I have extendedthe side rail portions" of the seat beyond the front'cross bar or edge thereof and have pivoted the foot rest" to these extended portions by Which construction the foot rest maybe freelyrai'sed. to a vertical position or even further back relative to the seat without injury to the pivotal connection; and the following is a detailed description of the present emb'odi ment of my invention and showing one means by which these advantageous results may be. accomplished With reference to the drawings, 10 desig nates the. seat portion of. a folding chair,

' which rails extend beyond the front edge of the cross bar 18 of the seat.

The foot rest 19 is formed of a suitable frame having side bars 20, end bars 21 and 22 and intermediate slats 23 and is supported at one end by means of legs'24, while at its opposite end the bar 21 is provided with suitable pivot pins or trunnions 25 the ends of which extend into openings 26 in: the extend: ing end portions of the rails 15 to pivotally; mount the foot rest with relation to the seat. This foot rest may be freely swung back and which is provided with the usual back rest j r 11 and legs 12, 13 and 1d. The backlegs 14 i i folded beneath the seat, as illustrated in" Figure 4, or it may be freely swung through an arcof substantially 270 to the raised position illustrated in Figure 5, without fear i of injury, in which position it will be noted that the cross bar 18 forms a strong and rigid stop limiting further movement of the rest in this position.

By this construction I am enabled to use a large and durable pivot pin of sufficient size I to resist unusual strains to which it maybe subjected and a construction is presented by which a raising of the foot rest relative to the seat portion is permitted and no undue I strain on either the pin or the rails is caused.

I have illustrated in Figure 6 a single trunnion 27 extending through the bar 21 3 instead ofa pair of trunnions, as illustrated v tion may be made;

The foregoing description is V directed solely towards the construction illustrated,

but I desire it to beunderstood that I reserve the privilege of resorting to all the mechani cal changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

'I claim: a I a 1. In a folding chair, a seat having side rails with connecting cross bars for supporting spaced slats the front cross bar being positioned a short distance from the ends of the rails, a foot rest having a frame with spaced slats supported therein and of a width to fit between the ends of said rails projecting beyond said front cross bar, pivoting means for connecting said frame to the projecting ends of said side rails, said pivotal means being located to permitsaid foo-t'rest and seat tobe folded intosubstantial parallelism in one direction, said front cross bar being disposed to lie above said pivoting meansfor providing'an elongated stop adj acent the point of pivoting to arrest the relative swinging of said footrest and seat in the other direction.

2. In a folding chair, a seat having side rails, front and back cross bars connecting said side rails, the front cross bar being positioned a short distance from the ends of said rail leaving said rails projecting there beyond, a foot rest having spaced end bars rigidly connected together, one of said end bars being positioned between said projecting rail ends and of a size. to substantially fill the space there between, pivotal connect ingmeans extending into said projections and also into said end bar therebe'tween to swingingly connect said seat and foot rest together.

In testimony whereof I aflix my signature.
