Description
V. M. WINTERS ADJUSTABLE CHAIR Filed Sept. Z5, 1963 Feb. l, 1966 United States Patent O 3,232,253 ADJUSTABLE CHAIR Verona M. Winters, 92'7 E. Capri Drive, Palatine, Ill. Filed Sept. 3, 1963, Ser. No. 306,023 1 Claim. (Cl. 10S-144) The present invention relates to adjustable leg furniture, and more particularly to a chair which may be provided with sectional legs. Thus, by removing or adding sections to the chair, the height of the chair over the floor may be varied. The primary object of this invention is to provide a means for adjusting the overall height of a chair so that at all times the correct height of the chair may be maintained in its relationship to a desk or table. More particularly, the present invention relates to chairs for children. It is rather important for a childs comfort and to promote better vision that the right height may be maintained between a childs chair and the height of the table where he eats, plays or studies.
The adjustable leg chair of the present invention may be formed of Wood, metal or even plastic, and the chair may be with or without arm rests. The chair with additional segments added to the legs may be used as high chair, and then as the child grows, the segments may be successively removed, converting the chair into a youths chair. When the child grows to adulthood, with all the segments removed, the chair becomes an ordinary chair. Each of the chair legs may be provided with a long screw bolt to hold the sections or segments. To add or to remove segments from the chair legs, all that is required is a simple screw driver to raise or lower it. As sections are removed from the chair legs, the long bolts in each leg are turned into the legs. When the last sections have been removed, the bolts will have reached the top of the chair legs.
This invention also consists in certain other features of construction, and the combination and arrangement of parts, to be hereinafter fully described, illustrated in the accompanying drawings, and specifically pointed out in the appended claim.
In describing the invention in detail, references will be made to the accompanying drawings, where like character numerals denote like or corresponding parts throughout the several views, in which:
FIG. l is showing the embodiment of the present invention applied to a conventional chair;
FIG. 2 shows the embodiment of the present invention applied to a conventional stool;
FIG. 3 shows a detail of one of the legs in the chair in FIG. l;
FIG. 4 is a view showing a detail of construction;
FIG. 5 is a modification;
FIG. 6 is a section taken on the line 6--6 of FIG. 4;
FIG. 7 is a modification showing the manner in which the segments in FIG. 5 may be formed out of metal; and
FIG. 8 is a section taken on the line 8 8 of FIG. 7.
It is to be understood that the present form of disclosure is merely for the purpose of illustration and that there might be various modifications thereof, Without departing from the spirit of the invention as herein set forth.
Referring now more particularly to the chair 10 with its adjustable leg means 11, best seen in FIG. l, made in accordance with the present invention, comprising, in combination, the chair seat l2; the chair rest 13; the four ordinary chair legs 14, 15, 16 and 17, respectively; and the removable segments or sections S which may be provided to lower or to raise the height of the chair above ground, as desirable.
It can be seen from FIGS. 3 and 4, that each segment S may be formed of a bead-shaped cylindrical block of wood or plastic 18 which may be provided with a transice versed vertical hole 19 ending at both extreme ends thereof with a pair of recessed openings 20 and 21, respectively. It can be discerned that a metallic insert 22, having an internal thread 33, is mounted in the end 24 of the leg 14 (each leg in the chair is provided with a similar insert). The insert 22 may be provided with serrations 25 to prevent it from turning in the chair leg. An elongated clearance hole 26 may be bored in the leg 14 (each leg in the chair is provided with a similar clearance hole, to allow the long screw bolt 27 to rise in the chair leg as segments are removed from the leg to shorten the height of the chair substantially as shown and described. The screw bolt 27 may be provided with a round head 27a which fits snugly into the recess 20 in the segment S.
FIG. 2 is a modification showing the manner of application of segmented legs to ordinary stools. The construction of the legs 14, 15, 16 and 17 in the stool S in FIG. 2 is similar to the one already described for the chair in FIG. l, in all of its details, and need not require any additional description.
FIG. 5 shows a modification in the segment design. The segments 28, 29 and 30, respectively, shown in FIG. 5 have a somewhat different outer configuration than the segments already described in FIGS. 1 to 4, inclusive. Otherwise, their overall construction and mode of application is similar.
FIGS. 8 and 9 show an additional modification. In this case, the segments shown in FIG. 5 may be formed of sheet metal. It can be discerned that the segments 31 and 32 may be each made of an upper section 33 and a lower section 34, respectively, which may be held to one another by means of the skirt-shaped circular flange 35, which lits into the shell formed by the lower section 33. The upper and lower sections 33 and 34 have hub extensions 36 and 3'7, respectively. The long bolt 3S, with its round head 39, passes through the Iholes 40 and 41, in the hubs 36 and 37, to mount the metallic segments 31 and 32 to the legs of a chair or a stool, substantially as described.
A careful examination of the foregoing description in conjunction with the invention as illustrated in the drawings, lwill enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty, sufficient to clarify the construction of the invention as hereinafter claimed.
Minor changes in shape, size and materials, and rearrangement of parts, may be resorted to in actual practice, as long as no departure is made from the invention claimed.
Having described my invention, what I claim is the following:
An adjustable leg of the class described for varying the height of a chair above the ground comprising in combination a chair seat, a plurality of legs under said seat, -an elongated `opening in each of said legs, a threaded stud in the extreme lower end of said opening of said legs, an equal number of segmented sections for each of said legs made of sheet metal comprising a pair of shells, an upper and a lower shell, the upper shell having a circular ange fitting into the lower shell to form said segmented sections, transverse vertical openings in said segments and a long screw bolt to mount an even number of segmented sections to each leg of the chair, said screw bolt passing through all of the vertical openings in each segmented section and being threaded in said threaded stud in the leg of said chair, the threading of said long screw bolt into said stud mounting said segmented sections to said leg, each of said vertical openings in each segmented section being provided with a recess at each end, each of said recesses being like in size and configuration, said References Cited by the Examiner UNITED STATES PATENTS 7/1882 Crawford 24S-188.4 1/1889 Baird 248-159 X CII Allnger 248-157 X Ehrlich 248-159 Richardson 312-265 X Dawson 248-157 X Drezner 108-144 X Martin 24S-188.2 Cottle 24S-157 FRANK B.
