H. V. KOOP CHILD'S CHAIR July 24, 1934.

Filed May 23. 1932 made/v 727 H.\/. KOOP 4 v-fuR/vev Patented July 24, 193.4


This invention relates generally to furniture,

and particularly to a child's chair.

The main object of this invention is the provision of an attachment for a standard straight back chair which will convert it into a childs chair.

The second object is the construction of a childs chair which can utilize the legs and seat of an ordinary dining room chair for the purpose of seating a child at a dining room table.

The third object is the construction of a chair attachment which will be exceedingly simple to manufacture, light in weight, and easy to apply to an ordinary dining room chair and which, when so applied, will be exceedingly stable in all directions.

The fourth object is to so construct the device that it can be folded up for carrying purposes and also that it shall include a container for articles belonging to or pertaining to the child.

The fifth object is to produce a chair attachment for converting an ordinary adults chair into a childs chair which will be compact in form and especially useful in eating houses.

These, and other objects, will become more apparent from the specification following as illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of an ordinary dining room chair.

Fig. 2 is a section taken along the line 2--2 in Fi 1.

Fig. 3 is a plan of the device.

Fig. 4 is a perspective view of the device in a carrying position.

Similar numbers of reference refer to similar parts throughout the several views.

Referring in detail to the drawing, the device itse1f.consists of a pair of upright sides 10 across the top of which is secured a seat 11 which may be covered with cane 12 or other material. At the rear end of the seat 11 is attached a folding back 13 by means of the hinges 14. The lower ends 15 of the back 13 abut against the rear edge 16 of the seat 11 when the back 13 is in an upright position. At the back of the upper end of the chair is secured a handle 1'? and a similar handle 18 is placed under the front edge of the seat 11.

Between the sides 10 is secured a cross brace 19, and a bottom board 20 extends from the board 19 to the slots 21 formed near the forward ends 22 of the side members 10. A closure board 23 is slidably placed in the slots 21. It is desirable to provide the board 23 with an opening 24 to facilitate the removal thereof.

The members 10 may vary somewhat in shape without departing from the spirit of this invention, however I prefer to have the rearmost ends 25 project some distance behind the back 13. It is also desirable to have the opposite ends of the members 10 provided with downturned lugs 26 in order to definitely position the device with relation to the seat 27 of the dining room chair 28. Also the rearmost end 25 will pass below the horizontal brace 29 commonly found in dining room chairs.

In order to insure a more universal application of the device to any style of chair seat there is provided a strap 30 which passes through slots 31 in the side members 10 which can be easily buckled around a chair seat 27, thereby prevent ing any tipping action or relative sliding movements between the chair seat 27 and the mem--- bers 10.

In order to prevent any marring of the finish on the furniture it is found desirable to cover the contacting surfaces with angular rubber pads 32.

In order to accommodate the device to up holstered chairs the lower edges 33 are cut away along a curved line to conform generally with is the contour of an upholstered seat.

It will be understood that in some instances it may be found desirable to employ arm rests as well as a tray similar to those now in com men use. in order that they will not interfere with the 'compactness of the device.

It will also be understood that the material from which this device is made is preferably wood, although it lends itself admirably to the use of steel and other materials.

I claim:

1. A childs chair comprising a pair of spaced vertical sides having means for rigidly securing same upon the seat of an ordinary straight back chair in a stationary parallel relationship, a seat secured across the top of said sides, said sides extending beyond the rearmost edge of the seat, a back hinged near its lower end to said seat in a manner that it can fold forwardly and downwardly against said seat, the lower end of said back engaging the rearwardly extending sides and the rearmost edge of the seat for the purpose of limiting the upright position of the said back when in use, and a pair of handles one of which is attached to the rear side of the back at the top thereof and the other to the under side of the seat near the front thereof which handles unite to serve as a single handle for carrying said pair when said back is folded downwardly.

These, of course, to be made foldable 2. A child's chair comprising a pair of parallel vertical sides spaced from each other and having downturned lugs at each bottom end thereof, a fixed seat secured across said sides, a back hinged to said seat, a horizontal floor between said sides under said seat, a vertical slide between said sides under the front edge of said seat, a wall under the rear side of said seat forming a brace between said sides, a pair of handles attached to the front edge of said seat and to the top of the back in a manner to serve as one handle when said back is folded against said seat, said vertical sides extending backwardly beyond the rear edge of the seat and forming a stop against which the lower end of the back can rest when in an upright position.
