ADJUSTABLE HIGH CHAIR Filed Feb. 18, 1947 ORV/LLE Z7- STEELE WW Z? M518]:
Patented July 11, 1950 UNITED STATES PATENT ()FFICE 1 Claim.
This invention relates to new and useful improvements in high chairs and more particularly to an adjustable high chair.
The primary feature of the present invention is to provide a high chair of the character referred to that is capable of being varied in height.
Another important feature of this invention is to provide a high chair that permits the seat and back to be packed and shipped separately from the supporting stand.
A still further feature of this invention is to provide a device of the character referred to that is neat and attractive in appearance, strong and durable in construction, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure l is a perspective view of the high chair constructed in accordance with the present invention.
Figure 2 is an enlarged fragmentary view in vertical section taken through the upright portions of the frame, the bar connecting said portions and the tubular legs and showing the locking pins and the compression springs therefor in elevation.
Referring now to the drawings in detail, wherein for the purpose of illustration, I have disclosed a preferred embodiment of the present invention, the numeral 4 represents generally the supporting frame having a pair of upright portions 5 and 6, said frame and upright portions being constructed of a substantially hollow tubing the upright portions 5, 6 being formed at the ends of a horizontal U-shaped base I.
Welded at 8 to the upper ends of said upright portions 5 and 6 are the outer ends of a connecting bar 9 substantially hollow throughout.
A pair of locking pins 10 and I I having one of their ends l2 hooked outwardly are slidably carried within bar 9 and extend outwardly through openings l3 provided in the respective uprights 5 and B.
A washer I4 is suitably secured at l5 to each of said pins and adapted to bear against one end of a coil spring [6 carried loosely on each of said pins, the opposite end of said spring bearing against a circular stop ll secured within the bar 9.
The hooked ends l2 of said pins are adapted to be pulled inwardly toward each other in a slot l8 provided in bar 9, whereby the outer ends of pins I and H are pulled inwardly of the bar 9 and against the compression of springs so that when the hooked ends of said pins are released the outer ends of said pins extend horizontally through uprights 5 and 6.
The numeral ll represents a seat having a back rest l8, foot rest l9 and a pair of L-shaped arms 20 preferably circular in cross section, said arms being secured at one end to the seat and the opposite end to the back rest.
A tray 2| having a pair of U-shaped brackets 22 is slidable on arms 20.
Extending downwardly from the forward corners of seat I! are a pair of tubular legs 23 and 24 having a plurality of vertically spaced openings 25 therein. Said legs ar telescoped to fit into upright portions 5 and 6 respectively and are held in vertical adjustment by the outer end of pins in and II selectively engaging openings 25 in said legs as is clearly illustrated in Figure 2.
To remove seat I! from frame 4 the hook ends of pins I0 and l I are pulled toward each other and the seat is lifted upwardly so that legs 23 and 24 disengage upright portions 5 and 6.
In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
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 of certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.
I claim:
In a chair, a seat, a single pair of legs for said seat at front corners of the same, a U-shaped base frame adapted to rest flat on a supporting surface and terminating in a pair of front tubular uprights with open upper ends in which said legs are vertically slidable, a tubular connecting bar between said uprights provided with a longitudinal slot therein, and fastening means for holding said legs against sliding comprising a pair of spring pressed pins in. said bar slidable into unfastening position and having curved hand grip ends extending out of said slot for grasping to slide the pins.
- ORVILLE D. STEELE.
