GENE B. HASBROUC K United States Patent RECLINING CHAIR Gene B. Hasbrouck, Corry, Pa, assignor to Corry Jamestown Corporation, Corry, Pa., a corporation of New York Filed June 14, 1966, Ser. No. 557,523 8 Claims. (Cl. 297361) ABSTRACT OF THE DISCLOSURE This invention relates to improvements in chairs of the type generally used in ofices and commonly known as chairs having adjustable features to suit the posture convenience and comfort of a user. More particularly, the invention is directed to structural features not generally available in chairs of this nature that enable adjustable of the chair to accommodate the users posture.
Despite the ability of currently produced chairs to adjust to change of tilt, change in force required for tilting and the chair seat height, there are many reasons why such chairs are inadequate to meet the variable requirements of the purchasing public. For example, there seems to be no attempt of chair producers to provide means by which a chair may have its seat, back, and armrests relatively coordinated to the convenient use by persons of varying stature, weight, or proportions. It is well known that no two individuals are quite alike. The chair industry, apparently, has failed to include in its design means for accommodating a chair to individuals whose general proportions in one way or another are not what might be considered as standard for a given age and height.
It is another and important object of the invention to provide means by which to adjust the chair back forwardly or rearwardly in adapting it to a short or long legged person.
A further object of the invention lies in provision of structure that enables a person to determine and set the chair back and arms in a relationship to the seat that is most comfortable, this being by way of inclining these parts with respect to the seat.
A still further object of the invention lies in provision of means for controlling the extent of tilt of the back and arms regardless of the set incline of these parts.
With the above and other objects-in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and more partially pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawings:
FIG. 1 is a perspective view of a chair embodying one form of the invention;
FIG. 2 is a front elevational view of the chair;
FIG. 3 is a side elevational view of the chair showing an intermediate position of the back and arms with respect to the seat, other positions of these parts being suggested by dash lines;
3,351,472 Patented .Fan. 2, 1968 FIG. 4 is a view similar to FIG. 3 shown in the relation of arms and back with respect to the seat when the arms and back are in a forward position;
FIG. 5 is a horizontal view taken directly beneath the chair seat and is taken in a downwardly direction as indicated by the arrows of line 55 of FIG. 3;
FIG. 6 is a partial view, partly in sections (see line 66 of FIG. 5) showing the arm and back support in their rearmost position with respect to the seat supporting iron;
FIG. 7 is a view similar to FIG. 6 and shows an adjusted position whereby the arm supports are moved slightly forwardly and into a generally vertical position thereby partially rearwardly inclining the back rest such as suggested in full lines of FIG. 3;
FIG. 8 is a view similar to FIG. 7 and shows an adjusted position of these parts when the back rest and arms are forwardly located with respect to the seat mounting iron;
FIG. 9 is a view showing the parts as adjusted in FIG. 7 with the chair iron tilted rearwardly;
FIG. 10 is an enlarged fragmentary View taken in substantial view as suggested by line lti1tl of FIG. 5 and shows the parts and control for iorward and rearward adjustment of back rest and arms;
FIG. ll is a transverse vertical sectional view of the structure shown in FIG. 10, being taken substantially on the line 11-11 of FIG. 10;
FIG. 12 is an enlarged fragmentary side view taken on line 12-12 of FIG. 5 and shows rearmost position for back rest and means for locking these parts (see FIGS. 3 and 7);
FIG. 13 is a view similar to FIG. 12 and shows the locking means released to enable adjusting the arms from position of FIGS. 7 and 12 to that of FIG. 8;
' FIG. 14 is a sectional View taken substantially on line 14-14 of FIG. 13;
FIG. 15 is a fragmentary exploded perspective view of the structure for locking the back rest and arms in any given adjusted position; and
FIG. 16 is an exploded perspective view of the various parts of the back rest and arm supports in their proper relationships.
Now with more particularly reference to the drawings, the oflice type chair shown in FlGS. l, 2, and 3 has several major components some of which are common to all chairs. These are: the seat 27, back rest 24, and arm rest 26, which are supported as a unit on the arms 12 and 13, so that the back rest, arm rests, and arms may be moved backward and forward relative to the seat 27.
The novely of this invention resides in the adjusting mechanism for the back rest, arm rests, and arms, which are adjustably supported on the seat iron 11 by means of the main pin 19 and which has the bolt 33 with hand wheel 21 thereon.
The arms are best shown in FIG. 16 and are generally L-shaped with a flange 23 at the upper end for attaching to the underside of the arm rests. The arms have an enlarged member at their lower end. The enlarged member has a flat innerside which rests against the outer edge of flange 3% on the seat iron 11.
It will be noted that the seat iron is generally in the form of a channel and has the downwardly extending flanges indicated and the upwardly struck ears 31, which are bored to receive the pin 16. The pin 16 passes through the holes in the ears 31 and through the holes in clip 32. The lower side of the clip is bored to receive the bolt 33. The lower end of the bolt passes through a hole 3 3 in the axle 15' and the hand wheel 21 is threadably received on the bolt 33. The outer ends of the axle 15 are received in the bores of bosses 35, as indicated. Thus, when the hand wheel 21 is tightened or loosened, the rear end of the arms will be swung up relative to the rear end of the seat iron about the center of rotation of the main pin 19, and thus the arm rests and back rest will be tilted relative to the seat 27.
The main pin 19 extends through the slots 38 in the arms and has the nut 39 threadably received thereon. The pin 19 also extends through the cam 17 and follower 1%. It will be noted that the follower 18 has a slot 40 that receives the main pin 19, and it is likewise received in the hole 41 in the cam 17. The threaded end of the pin 20 is threadably received in hole 42 in the follower 18. Thus, when the hand wheel 21 is rotated, the follower is moved by pin 25 relative to the cam and it exerts a force on the end of the main pin 19 adjacent its head 43, thereby clamping the arms and chair iron together. Thus, the hand wheel 26 can be rotated to loosen the cam 17 and follower 18 relative to each other, and when cam 17 is loose the arms can be slid forward and backward to move the main pin 19 rearward or forward in slot 33 thereby moving the arms forward and backward to adjust the eifective length of the seat 27 ahead of the back rest 24.
The arms can be tilted forward and rearward relative to the seat by adjusting hand wheel 21 to swing the arms and seat iron relative to each other.
The chair is supported on the pedestal 14, which has a lower end as indicated received in the base 23, and the main pin 19 extends through the hole 45 in the pedestal 14. Thus, the seat iron can be rocked forward and backward by adjusting the hand wheel 20 in a more or less conventional manner.
