Salem, Oreg. Application August 1, 1950, Serial No. 177,082 (Cl. 155131) 1 Claim.

with the conventional dining room chair whereby a child may be seated in a comfortable position at a dining room table, breakfast room table or in a motor vehicle.

Various devices have been provided for elevating seats for children in dining rooms, restaurants, motor vehicles and the like but the conventional folding seat of this type is either attached to a chair or table and because of the different styles of chairs it is difficult to install a are objectionable because, not being foldable, valuable floor space is taken up thereby. With this thought in mind this invention contemplates a seat mounted on two folding frames with legs on one frame positioned to rest upon the seat of a chair and with the other frame positioned to extend to the floor whereby the seat is positively supported on the chair and floor.

The object of this invention is, therefore, to provide a folding frame for a seat whereby a child's seat may be positioned in an elevated position on a chair and, at the same time partly supported from the floor.

Another object of the invention is to provide a folding seat support in which the elevation thereof is adjustable.

A further object of the invention is to provide a collapsible childs seat support for retaining a seat in an elevated position above a chair or the like which is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a substantially horizontally disposed frame with elongated slots in side rails thereof and with extensions at the rear positioned to be supported on the seat of a chair, a seat positioned on said horizontally disposed frame, a, vertically disposed frame pivotally mounted on the outer ends of the rails of the horizontally disposed frame and diagonally positioned braces pivotally mounted on the vertically disposed frame and having thumb screws in the inner ends whereby the inner ends of the braces are slidably mounted in the elongated shown in dot and slots of the rails disposed frame.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:

Figure 1 is a side elevational view of the childs portable folding high seatshowing the end of the device supported on a chair, the chair being dash lines.

Figure 2 is a front elevational view of the seat supporting frame.

Figure 3 is a plan view showing the seat and supporting frame.

Figure 4 is a vertical longitudinally disposed section taken on line 44 of Figure at the sides of the horizontally Figure 7 is a detail illustrating a sliding section in one of the side rails of the horizontally disposed section of the frame.

Referring now to the drawings wherein like posts [5 and I6 pivotally mounted in the outer and I2 by a shaft l1, and' diagonal braces l8 and I 9, the inner ends of which ends of the rails l i desired. A similar strap 3| extends from the lower edge of the bar 26 to the shaft IT, as; shown in Figures 3 and 4.

The side rails II and I2 of the horizontally disposed frame are provided with inserts 32 which are C-shaped in cross section, as shown in Figure 7 whereby slots 33 are provided in the outer surfaces, and heads 34 of bolts 35 are positioned in these inserts with shoulders 35 on the bolts positioned in the slots. The thumb nuts 20 and 2| are threaded on the outer ends of the bolts 35,

on each side of the frame, respectively and sleeves 5 The lower ends of the posts te and-tda-reretained in spaced relation by a rod ll.

Caps of rubber or other restlql epr rt:;mate gal; indicated by the numeral 42 are providedpn the lower ends of the legs 13 and M to prevent scratching or maring seatsor other parts of furnitore; mponwhich-theseatmay, be used.v

With the 1 parts arranged in this manner theframes are folded for storage, shipping. and the like-and when it; is: desired to; usertherseatzthe vertically disposed;trameeisextended-to snbstantially avertical-positionand withthe legs. at the inner end of thee horizontally disposed frame positioned upon-.a t-sea or iparts thereoi"the-posi tion. of the vertically dis-posed frame is adjusted until the seat is substantiall-yalevela nuts are tightenedstoretain thepartsin-the-adjusted positions.

What is claimed is:

In a folding elevating seat, the combination which comprises a first frame having side rails with integral legs having caps of resilient material on the lower ends, said legs being extended downwardly from the inner ends of the said side rails, said side rails having longitudinally extendeds elopgatedgsslots in ending relatively spaced transversely extending supporting bars fixed at their respective ends to said side rails, a seat carried by the supporting bars connected to the sadidsifidmils; ofgthecfirst frame and positioned on the fran e,sg thatthe seat extends from a point intermediate the ends of said frame toward one of said ends, a second frame having posts at its sidesgptvotallyattaehed to the outer ends of the railsloi} the first frame, diagonal braces pivotally attached to the posts of the second frame at one end and mounted for longitudinal sliding movement-in relationto saidgsiderails; the slots of the'side railsgofthe-first frame-at the other end by bolts with I clamping the ends ofthe diagonal braces in the otsnithe ide a lsof the first frame.
