Claims.
This invention relates to new and useful improvements in an adjustable chair.
The invention proposes an adjustable chair which is characterized by a flexible frame having a pair of spaced forwardly extending feet portions for resting on the ground and continuing into upwardly extending front portions continuing into rearwardly extending side portions, and a transverse back portion for supporting a chair back depending from the rear ends of the side portions in a particular manner.
More specifically, it is proposed that the chair back be pivotally mounted on said transverse back portion.
Still further the invention proposes the provision of a chair seat pivotally connected with said chair back and extending forwards and rested on said horizontal bar and adapted to maintain various positions on the horizontal bar.
Still further the invention proposes an arrangement for varying the distance of said transverse back portion from said side portions.
For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.
In the accompanying drawing forming a material part of this disclosure:
Fig. 1 is a perspective view of an'adjustable chair constructed in accordance with this invention.
Fig. 2 is a'perspective View of the chair shown in Fig. 1 with the parts in a different position.
Fig. 3 is a fragmentary enlarged vertical sectional View taken on the line 33 of Fig. 2.
Fig. 4 is a fragmentary elevational view looking in the direction of the line 44 of Fig. 2.
Fig. 5 is a side elevational View of an adjustable chair constructed according to a modification of this invention Fig. 6 is a fragmentary enlarged perspective detailed view of a portion of Fig. 5 looking in the direction of the line 6-6 of Fig. 5.
Fig. 7 is a horizontal sectional view taken on the line I-'I of Fig. 6.
Fig. 8 is a vertical sectional view taken on the line 8-8 of Fig. 7.
Fig. 9 is perspective view showing a covering material used for the chair.
Fig. 10 is an enlarged perspective detail view of Fig. 9.
The adjustable chair, in accordance with this invention, includes a fiexible frame I0 having.
a pair of spaced forwardly extending feet portions Ill for resting on the fioor and continuing into a pair of upwardly extending front portions Iii continuing into a pair of rearwardly extending side portions ID". A horizontal bar II is mounted across the front portions If) at an intermediate height. A transverse back portion l2 depends from the rear ends of the side'portions I 0. A chair back I3 is pivotally mounted on said transverse back portion I2. A chair seat I4 is pivotally connected with said chair back I3 and extends forwards and rests on said horizontal bar I I and is adapted to maintain various fixed positions on said horizontal bar.
The forwardly extending feet portion Ill are provided with downturned rear ends Ill and downturned front ends IB The forwardly extending feet portions II] rest upon these downturned ends 10 and It. An auxiliary horizontal bar II is mounted across the upwardly extending front portions II! at a point below the horizontal bar II.
In the form of the invention illustrated in Figs. 1-4 inclusive the transverse back portion I2 depends from the rear ends of the side portions m by reason of downwardly extending portions Ill which connect the rear ends of the side portions II with the ends of the transverse back portion I2. Several loop elements I5 are welded to the sides of the chair back I3. The transverse back portion I2 extends through these loops I5. The chair back I3 comprises substantially a frame section having side arms I3 a bottomarm I3", and a top arm I3. The top arm I3 is set rearwards of the top ends of the side arms I3.
The chair seat I4 comprises a substantially U- shaped member having side arms M", a front arm M which is offset downwards from the ends of the side arms I l The rear ends of the side arms I 4 are pivotally connected with the bottom ends of the side arms I3 of the chair back by pintles I6. Several transverse bars H are mounted between the side arms M Toothed shaped members I 8 are formed upon, or mounted upon the bottom sides of the side arms I4 and are adapted to engage the bar II to hold the chair seat I4 in the various fixed positions previously mentioned.
Fig. 1 illustrates the adjustable chair in one condition. It may be placed in the condition shown in Fig. 2 by first lifting the front end of the seat I4 and then forcing the seat rearwards and allowing the front end to move downwards so that the toothed shaped members I8 re-engage the bar H in a difierent position. This adjustment changes the inclination of the chair back.
In Figs. 5 to 8 inclusive a modified form of the invention has been disclosed which distinguishes from the prior form in the provision of a means for varying the distance of the transverse back portion 12' from the side portions ID. More specifically, each side portion REF has a tubular member mounted on its rear end. An anchor member 2| is disposed within each tubular member 20. Each anchor member 2| is attached to one end of a cable 22. A tubular member 23 is threadedly engaged in the rear end of each tubular member 20 and serves to firmly hold the anchor members 2! in position. The extended ends of the cables 22 engage into the ends of the transverse back portion l2. The transverse back portion I2 is of tubular construction. Each end of the transverse back portion I2 is formed with a split 25 having lugs 26 upon the sides thereof. A screw El engages through One of the, lugs and threadedly engages the other of the lugs of each end of the transverse back portion, whereby the screws 21 may be turned tight for clamping the cables 22 in position.
In Figs. 5 and 6 the adjustable chair is shown in one condition. The transverse back portion I2 is capable of swinging forwards and rearwards on the cables 22. the distance of the transverse back portion l2 from the said side portions H3 it is merely necessary to loosen the screws 21 and then let in or pull out the cables 22 from the ends of the transverse back portion l2.
In other respects this form of the invention is similar to the previous form and like parts are identified by like reference numerals.
In Figs. 9 and 10, the chair covering material 30 is shown to be secured in tubular end members 3| slotted at 32. The covering material made of a backing sheet of leather 33 and a front corrugated sheet of leather 34, are joined together by stitches or the like 35. The ends of sheets 33 and 34 are folded over to form a heavy edge 35, to prevent the covering material 36 from sliding out of the slotted tubing 3 I.
In other respects this form of the invention is similar to the previous forms.
While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
