Application April 22, 1948, Serial No. 22,691

The present invention relates to a novel and improved chair which 'is provided `with practical and eilicient adjustment facilities whereby the one chair may be used to advantage by both children and adults.

It is a matter of common knowledge that babies may be accustomed to using high chairs and also small chairs in the toy category. When, however, they begin to grow, there becomes a stage of development in which neither high chairsgnor small chairs aresuitable for their needs andpurposes, particularly while eating from the conventional type tables. Many makeshift provisions are therefore adopted, such as sitting on pillows, on books and the like. To say the least, these makeshift methods are wholly unsafe and impractical.

With the foregoing diilculties in mind, I have evolved and produced a chair which includes not onli7 adjustable legs but a complemental adjustable foot rest, the two together serving the aver-v age needs and requirements of growing children. More specifically, in carrying out the principles desired, I utilize extensible and retractible aux-v iliary legs for adjustment purposes and these are tted telescopically into main tubular legs.

Another phase of the invention has to do with a special frame which is suspended from the bottom of a chair said frame serving as an adapter for a vertically adjustable foot rest or step.

Other vfeatures and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed'to designate like parts throughout the same:

Figure 1 is a perspective view of a kitchen or equivalent chair constructed in accordance with the principles of the present invention;

Figure 2 is an enlarged sectional view which may be said to be taken approximately on the vertical line 2-2 of Figure 1, looking in the direction of the arrows;

Figure 3 is a fragmentary sectional and elevational view showing one of the extensible legs;

Figure 4 is a perspective view of a bracket;

Figure 5 is a perspective view of one of the leg frames; Bind n Figurel is a perspective view ofthe foot rest adapter frame.

Referring now to the drawings by distinguishing reference numerals, it will be seen that the leg frames, which are of U-shaped tubular forms used in so-called metal chairs, are denoted by the numerals 8 and 9 and these are duplicates 1 Claim. (Cl. 155-172) and the bight portions I0 (see Fig. 2) are suitably screwed or otherwise fastened to the under side of the cushionedV bottom II. The back rest is denoted by the numeral I2 and is of suitable construction and attached to the chair bottom as shown. The legs proper which are vertical are denoted by the numerals I3 and they are provided with vertically spaced and aligned bolt holes I4 to accommodate the screw-threaded portion I5 (see Fig. 3) of a thumb bolt I 6. The bolt is placed in selected bolt holes and has a stud I1 on its' inner end to t into a stud hole provided in the tubular extensible and retractible leg I8. This is a small tubular member, as shown in Figure 3; and has a suitable foot I9 screwed into place, as at 2D. legs, the height of the chair bottom may be regulated to the plane desired and to accommodate different sizes of growing children.

The foot rest adapter frame is denoted by the numeral 2l in Figure 6. This comprises a tubular rectangular frame, the mid portion 22 of which is bolted to the under side of the chair bottom as shown in Figure 2.

The vertical limb portions are denoted by the numerals 23y and like the chair legs are provided with bolt holes to accommodate studs on thumb bolts 24, which thumb bolts are carried by sleeves 25, the sleeves being slidable on said limbs as shown in Figure 2. The sleeves carry triangular brackets 26 which in turn serve as supports for the step or foot rest 21. There is a cross brace or strut 28 forming the remaining part of the adapter frame and this has its end portions suitably attached between the front legs I3 oi the chair as shown better in Figure 1.

Novelty is predicated upon the extensible and retractible telescoping sleeves I8 which constitute adjustment legs and which are provided with detachable feet and are adjustably bolted in the regular tubular legs I3. Further novelty is predicated upon chair legs with adjustable feet in conjunction with a foot rest on the front legs, which foot rest is adjustable to coincide with the adjustment made in reference to the legs.` More specific novelty is predicated upon the construction of the foot rest, the brackets and the adapter frame means 2| which is employed to accommodate the foot rest.

In view of the foregoing description taken in conjunction with the accompanying drawings, it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed descriptionv is accordingly deemed unnecessary.

By extending and retracting the auxiliary It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention, the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and within the scope of the appended claim.

Having described the invention, what is claimed as new is:

A chair o1 the class described comprising a horizontal bottom having a vertical back rest, a pair of duplicate spaced parallel vertically disposed U-shaped leg frames having their bight portions attached to the underside of said bottom,

said leg frames providing front and rearleg's, a

third U-shaped frame, smaller than the first-` named U-Ashaped frames, said third'frame hav ing its bight portion attached tothe underside of the forward edge portion of said bottom and its limb portions depending in spaced parallelism between the respective front legs of the rst- .0

named lleg frames, a horizontal cross brace oonnected to the lower ends of the limbs of said third U-shaped frame, said cross brace being connected 4 at its opposite ends to the lower portions of said front legs, and a foot rest slidably mounted on the vertical limbs of said third U-shaped frame.
