Feb. 13, 1951 H. J. CRINER BRACKET SUPPORTED FOLDING CHAIR Filed Oct. 15, 1945 Patented Feb. 13, 1951 BRACKET SUPPORTED FOLDING CHAIR Harry J. Criner, Davenport, Iowa, assignor of onehalf to A. G. Bush, Davenport, Iowa Application October 15, 1945, Serial No. 622,373

1 Claim.

My invention relates to seats for infants and the objects of my invention are to provide an adjustable folding seat which can be readily attached to and removed from the back of an ordinary household chair, or the back of an automobile seat, church pew, waiting room seat, or any other suitable support, which will hold an infant securely and safely, can be adjusted as to height and. can be folded up into a very small compass for traveling or when not in use; to provide such a seat which can be conveniently carried and used at church, at a picnic, at work in a garden, etc.

I attain these objects by the means illustrated in the accompanying drawings, in which,

Figure l is a'si-de elevation of my seat applied to a common form of chair;

Figure 2 is a front elevation of the seat attached to such chair;

Figure 3 is a top or plan view of my seat attached to the back of an ordinary household chair;

Figure 4 is a side view of my seat in folded position;

Figure 5 is a detail showing an alternate form of hinge to attach the back to the base;

Figure 6 is a detail showing a toilet form of base;

Figure '7 is a detail showing the back suspended on a tree.

Similar numerals refer throughout the several views.

My invention comprises a back or seat 2 with a base 5 having its rear edge pivotally united or hinged to the back preferably by short hinge bars l screwed or otherwise firmly attached to the base by screws M and pivotally united to the back by pivot pins 1.2. Any other suitable form of hinge may be used, such as a piano hinge [9 shown in Figure 5.

Arms extend forwardl from the back and their rear ends are pivotally united to the back by bars 6 and pivot pins 6.2. The bars 6 are rigidly united to the back 2. Brackets 3.| are formed integral with the arms 3 and extend downwardly therefrom and are arranged to bear against the back 2 when the seat is in open position, to form a firm support for the arms. At the front end of the arms a shelf or table 4 is mounted. necting bars or links 5 are pivoted which extind downwardly and their lower ends are pivotally united to the side edges of the base I with pivots Ll.

When the parts are so arranged, the base I to similar parts To the front ends of the arms c'onmay be folded up against the back as shown in Figure 4. The arms also will fold up against the back and extend far enough above the back so that the shelf it will lie in substantially the same plane as the back 2.

Various forms of support to secure the seat to the back of a chair, automobile seat or other support, may be utilized but I prefer a fixture having a pair of hooks l5 united by a crossbar. The hooks are adapted to embrace the top of a chair back or the back of an automobile seat, church pew, or other similar support. This fixture is preferably made of a metal rod covered with a rubber or other soft covering.

At the middle of the crossbar I secure a peg or button i i. To the back I attach the lower end of a wide band 8 of fabric or other suitable material provided with spaced openings or eyelets is formed or secured in the free portion thereof. These openings or eyeletsare made of the right size to embrace the peg or button II whereby the seat may be suspended at the desired height above the seat of the chair to which it is attached, and when so adjusted, the seat M of the chair will form a footrest for the occupant of the folding seat. My seat may also be suspended from a garden fence or from a nail 2| driven in a wall, tree or post 22.

In the operation of my seat, it is first opened or unfolded. The hook is placed in position upon the back of the chair or automobile seat, or other support. The back of my seat is placed in juxtaposition with the back of the chair or automobile seat at the desired height and the proper eyelet is then placed over the peg or button H in the crossbar of the hook. The child can then be seated upon the base and its weight will keep the seat in its open position. The brackets 3.! under the arms 3 will prevent the arms dropping down and the links or bars 5 will hold up the front of the base.

The height of the appliance can be adjusted without removing the infant by detaching the strap 8 from the peg H and either lowering or raising it and attaching the proper eyelet to the peg. The seat of the chair or pew or automobile seat will form a support for the feet of the child and the arrangement of the base and the shelf will prevent the child from displacing the seat by jumping or trying to stand. The weight of the child pressing downward upon the strap 8 and the friction of the back with the back of the chair or automobile seat will prevent tipping or tilting of my seat laterally. v

The chair [6 to which this seat may be attached will have a somewhat larger base than the ordinary highchair and there will be no danger of a child tipping backward because his feet will be pressing downwardly upon the front of the seat of the chair on which the appliance is mounted, and the back of the chair, if a solid back, or a crossbar l8 will prevent the base from moving rearwardly.

The base of my seat may be of either wood or metal and the back and base may be padded if desired and the rear side of the back may be covered with felt or any other desired material to prevent scratching the chair or other support on which it is mounted.

To close the appliance, the base and arms are folded upwardly against the back, into a very small compass, as shown in Figure 4.

When at picnics, a convenient support may be made by driving a nail 2| into a tree 22 at the desired height.

My seat may be utilized as a toilet seat by cutting a suitable hole 20 in the base as shown in Figure 6,.under which any suitable receptacle may be placed upon the seat of the chair.

When my seat is thus mounted upon an ordinary chair, it will be held stable more than an ordinary highchair because the legs I! of the chair will afford a broader base for the chair to stand on than the legs of the ordinary highchair and the infants feet resting upon the seat Id of the chair will tend to prevent the chair from tipping over backward.

It is obvious that the size, form and arrangement of the parts may be modified without departing from the spirit of my invention and I do not limit my claims to the precise forms shown in the drawings.

If desired, a peg or pin may be secured in the back of a chair with which my seat is used, and in that case the band 8 may pass directly over the back of the chair and have an opening or eyelet engaged with such peg or pin, then avoiding the use of the hooks.

I claim:

In a folding seat for children, a back, a seat pivotally united at the rear of the seat to the lower end of the back, arms having their rear ends pivotally united to the back and spaced above the seat, triangular brackets united to the lower edges of the arms at the rear end thereof extending downwardly and arranged to bear against the back and support the arms when in open position, and pivoted'links connecting side edges of the seat near the front thereof to the inner edges of the arms near the outer ends thereof whereby the arms will support the front of the seat when in open position.
