FOLDING CHAIR Filed Sept. 22, 1957 BY 5 a Y ATTORNEY Patented Oct. 4, 1938 UNITED STATES PATENr OFFICE 2,131,722 FOLDING 01mm Glen J. Arthur, Davenport, Iowa Application September-22, 1937, SerialNo. 135,138

2 Claims.

My present invention relates to folding nursery chairs andis in the nature of an improvement upon the structure shown in my Patent No. 1,910,736, issued May 23, 1933. Inasmuch as the construction in the center of the seat of the chair has not been essentially changed, I have v refrained from illustrating this in' the present drawing, it being possible to determine this construction from my prior patent. The present invention pertains more particularly to the locking mechanism for the tray and the latch for holding the chair against accidental folding.

Among the objects of this invention are to provide improved means for latching the tray in position on the chair arms; to provide improved means for latching the back to one of the arms so as to prevent inadvertent collapsing of the chair; and such further objects, advantages, and capabilities as will hereafter appear and as are inherent in the construction disclosed herein.

In the drawing annexedhereto and, forming a part hereof,

Fig. 1 represents a side elevation of my improved chair in assembled and latched position, ready for use;

Fig. 2 represents this chair with the tray in 7 position ready to be placed on the arms and secured in place thereon;

Fig. 3 represents a fragmentary edge view of one end of the tray and illustrating the projection from the bottom of the tray which cooperates with an arm in holding the tray in position thereon.

I shall now refer in greater detail to the an- 35 nexed drawing for a more complete description of this invention. A pair of loops I and 2, hinged together at 3 form the legs for supporting the seat 4. The ends of the loop I are pivotally connected by a pair of bolts 5 which also connect 40 the uprights 5 of the back I to the seat 4. A

pair of arms 8 are pivotally connected at 9 to the uprights 6 and at It to the posts H. The

lower ends of these posts II are pivotally connected at I2 to the seat 4, the pivot points 5, 9,

45 Ill, and 12 forming the angles of a parallelogram.

A stud I3 projects laterally from one of the uprights 6 and is designed to be engaged by the notch M in the latch member I5. It will therefore be apparent that when the latch member I5 50 is engaged, as shown in Fig. 1, the chair will be held from collapsing unintentionally.

A tray l6 has downwardly projecting elements H which engage outsideof the arms 8 and are provided with inward extensions l8 which en- '65 gage under the-arms. These downward projections l'l guide the tray with respect to the arms 8 and the extensions l8 abut against the for-- ward side of the posts II when the tray is shoved back into its proper position. Projections l9 extend. forwardly and upwardly from the posts ll 6 and engage in front of the extensions l8 when the chair is completely set up, as illustrated in Fig. 1. From the foregoing it is apparent that when the chair is assembled and set up, as in Fig. 1, with the latch member l5 engaging the 10 stud l3, as shown in this figure, it will be impossible to. remove the tray IS without bending or breaking some part of the chair, unless the latch I5 is first disconnected from the stud Hi.

When it is desired to use the upper'part of the 16 chair with a toilet seat, the nuts may be removed from the bolts 5 and the legs detached so that downward projections 4a and 41) from the seat 4 may fit within the opening in the toilet seat and hold .the two against any substantial relative 20 movement. The opening in the chair'seat has not been shown in the present drawing since it does not differ essentially from that shown in my prior patent referred to above.

While I havedisclosed what is now regarded as 25 the preferred embodiment of this invention, I desire this disclosure to be regarded as illustrative only and not to be interpreted in a limiting sense.

Having now described my invention, I claim:

1. A folding chair comprising in part a-seat member having a back pivotally connected thereto to swing forwardly and backwardly with respect to the seat, into open and folded condition, arms pivotally connected to the back and extending above and substantially parallel to the sides of the seat, posts pivotally connecting the forward end portions of the arms to the sides of the seat membenand a tray slidable on the arms and having downwardly projecting elements having laterally extending ends to engage the arms and guide the tray with respect thereto, said ends being slidable along the under side of said arms into engagement with said posts, and said posts having projections extending forwardly therefrom and upwardly into positions in front of said ends whereby to prevent the tray from being removed from the arms.

2. A folding chair comprising in part a seat member having a back pivotally connected thereto to swing forwardly and backwardly with respect to the seat, into open and folded condition, arms pivotally connected to the back and extending above and substantially parallel to the sides of the seat, posts pivotally connecting the forward end portions of the arms to the sides of the seat member, a tray slidable on the arms and moved from the arms, a latch member pivotally having downwardly projecting elements having connected to an arm and provided with a slot laterally extending ends to engage the arms and for engagement with a cooperating stud, and a guide the tray with respect thereto, said ends bestud projecting from one edge of the back and ing slidable along the under side or said arms arranged to be received in said notch and to cc- 6 into engagement with said posts, and said posts operate with said latch member in holding the having projections extending forwardly therechair against folding.
