CHILDS FOLDAIBLE TOILET-CHAIR.

Specification of Letters Patent.

Patented Sept. 2'7, 1921.

Application filed October 3, 1919. Serial No. 328,212.

7 To all whom it may concern:

Be it known that 1, WILLIAM C. RATHJEN, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Childrens Foldable Toilet- Chairs, of which the following is a specification- This invention comprises improvements in the construction of foldable chairs to be used by children for toilet purposes. The construction is adaptable for use, also, for other purposes.

The chair is capable of being so folded that it can be carried in a suitcase or a small package.

Simplicity and cheapness of construction, compactness when folded, and rigidity when unfolded are some of the advantages of this device.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur,

Figure 1 lid up; 7

Fig. 2 is a front elevation;

Fig. 3 is a side elevation;

Fig. 4 is a top elevation with the lid down and the device as a whole folded;

Fig. 5 is a top plan view, showing the device folded, but with the lid up; and

Fig. 6 is a sectional view on the line 66 in Fig. 4.

Figs. 1, 2, and 3 of the drawings show the chair unfolded and ready for use. Figs. 4, 5, and 6 of the drawings show the device folded and ready for packing away or transportation. I

The legs 1 are pivoted by pins 2 to front and rear members 3 and 4, and seat, when unfolded, in notches 5 in the seat 6, having the opening 7. The flange- like members 3 and 4 are attached to and depend from the seat 6.

The step 8 is fastened to the seat 6, and extends slightly to the rear of the same, so as to overlap rear member 4, the rearward notches 5 passing through the step 8 as well as the seat 6. V

Hinges 9 fasten lid 16 to step 8.

Hooks 11, by means of eyelets 12, attach the lid 10 to the side arms 13, when the chair is in unfolded position, thus adding to its stability or rigidity. Hooks 14 are borne by the ends of a piece of tape 10 or strap is a top plan view with the I from eyelets 12.

or the like. The said hooks 14 are hooked in the eyelets 15attached to side arms 13. The purpose of the strap or tape 10 orthe like when hooked in place, as just stated, is to hold the child in the chair. Children using such a chair are usually quite young and need to be supported from falling out by some such means.

The legs 1 are braced by tie-rod 17 which imparts solidity to the structure, especially so as to free legs .lfrom binding on the corners 18. This outward movement is not absolutely essential, but, if desired, is permitted by the grooves 19 being made to extend far enough toward the ends of front and rear members 3 and 4 to permit of it.

The pins 2 fit in grooves 19 and slide therein while the chair is being either folded or unfolded -in opposite directions, according to which of these operationsis being performed. The grooves 19 extend towardthe middle of'the length of front and rear members 3 and 4, the said grooves extending far enough toward the said center to enable the legs, when folded, neatly to underlie the seat 6.

The chair as a whole is preferably formed in the shape of a square, or in approximately that shape, the width of the seat and length of the front and rear pieces 3 and 4 being substantially identical with the length of the legs plus the thickness of arms 13. Thus, when folded, a very neat and compact package is formed. The feet of legs 1, when folded, contact with the inner or underneath side of arms 13, and as one pair of legs is pushed in from one side and the other pair from the'opposite side, the arms 13 limit the movement of the opposing pairof legs, and both pairs of legs and the arms 13 are made to lie neatly within pieces 3 and 4-and underneath seat 6.

It will be observed that there are two grooves 19 in member .3 and two grooves 19 in member 4, the same extending in opposite directions from approximately the ends of the said members 3 and 4:, and the innermost point of the said grooves 19 being respectively past the center of thelength of members 3 and 4;, thus allowing pins 2 to travel as far inwardly as is necessary to permit the legs 1, arms 18, and tie-rods 17, when folded, completely to underlie seat 6, one of the said leg members, when thus folded, underlying the other.

The lid 10 is notched at 20, so that when erect the notched part will underlie arms 13 and assist in steadyin'g the structure.

Having thus described this invention, I hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as it is evident that many minor changes may be made therein without departing from the spirit of this invention or the scope of the following claims.

I claim:

1. In a folding chair of the character described, a seat provided with notches on its opposite sides having depending flanges on two opposite sides thereof, a pair of side members having supporting legs to be re ceived in said notches when the chair is unfolded, said flanges on the seat having superposed grooves therein extending inwardly from a point adjacent the notchesin the chair to a central point where they overlap, each of said side members having a pivoted slidable connection in one of said grooves in each of said flanges, whereby said side members and legs may be moved to underlie the seat in superposed relationto each other.

2. In a folding chair of the character described, a seat provided with notches on its opposite sides having depending flanges on two opposite sides thereof and notches in the side edges thereof, a pair of side members having supporting legs to be received in said notches when the chair is unfolded, said flanges on the seat having superposed grooves therein, each of said side members having a pivoted slidable connection in one of said grooves in each of said flanges, whereby said side members and legs may be moved to underlie the seat in superposed relation to each other.

3. Ina folding chair, the combination of a seat member having notches in the side edges thereof, there being a pair of flangelike members depending from the said seat, a pair of side members comprising arms and legs, the said legs being received in the said notches and pivoted in relation to the said seat, said legs extending farther below the seat than the arms extend above the seat and the said pivotal points being approximately where thele s and the arms begin, the pivots of each side member being slidably mounted in grooves in the said flangelike members, said grooves being arranged one over the other and extending inwardly from said notches to a point where they overlap, whereby the side members may be folded to underlie the seat within its confines and in superposed relation.

In testimony whereof I hereunto affix my signature.

WILLIAM C. 'RATHJ EN.
