HOFFMAN, JR RECLINING CHAIR WITH ADJUSTABLE OTTOMAN BRACKET Filed Sept. 18, 1957 Jan. 17, 1961 INVENTOR 2 Sheets-Sheet 2 ATTORNEY!)- This invention relates to reclining chairs. and moreparticularly to reclining chairs having'adjustable ottoman brackets. i
"Many reclining chairs haye been developed with leg rests having an upward and forward movement coordirated with the movementof the chair. 'In'most reclining chairs however, the leg rest i's fixed ontheoperatin'g' linkage, limiting the movement of the, le'g rest indepen dently of the linkage. The desirable feature, ofjadjustab'ility' in accordance with the desires of'the occtlpairitof chair is therefore lacking. i
important object of this inventionis to provide an ottoman bracket which is adjustable independently of the operating linkage.
Another object of this invention is to provide an adjustable ottoman bracket having movement about its pivot whiclrmay'be regulated inaccordance'with the requirements and'desires-of-the individual.
In attaining these objects, one feature of the invention residesfin the arrangement of a reeli'riing chaiihaying a reclining-member which is; movable with respect to the stationary framework and an adjustable [ottoman carried by a linkage connected to the reclininginember andthe stationary framework so that movement of the reclining member to reclining position extends the adjustable ottoman to a position'upwa'rd' and'forwar'dly of"the"'chair. Stops control the ottoman so that in retracted position the bracket extends vertically in front of the chair to form a front panel. Other stops limit adjustment of the ottoman about its pivot point relative to its supporting linkage when in extended position.
These and other objects and advantages of the invention will become apparent from the following specification and drawings wherein:
Fig. l is a sectional side view of the reclining chair embodying the invention in its preferred form;
Fig. 2 is a sectional side view of the reclining chair shown in Fig. 1 with one of the operating linkages of the chair and adjustable ottoman brackets fully extended;
Fig. 3 is an enlarged top view of one of the operating linkages shown in Fig. 1;
Fig. 4 is an enlarged side view of one of the operating linkages and adjustable brackets shown in Fig. 1, with the adjustable ottoman bracket shown in both its normal and retracted position.
The reclining chair generally indicated at 10, has a stationary framework 12 and a reclining member 14 including seat 16 and a back 18 which are rigidly connected and operate as a unit. Attached to the stationary framework 12 is a substantially horizontally extending bracket 20, preferably of metal construction, extending from the front to the rear of the chair intermediate the height of the stationary framework. A second metal bracket 22 carries a depending arm 24 pivoted to bracket 20 by pin 26 at its end. Reclining member 14 is supported by bracket 20 for pivotal movement relative to the stationary framework 12.

One end of lever fitl is pivoted to amend of lever 50 at 64 and the other errant lever 60 projects beyond lever 28 and is PiYQted at 66-to an end of a guide link 68.

The described operating linkage moves the adjustable ottoman bracketlfroma retracted position in front of the chair; upward anjd forwardly to an extended position upon movement of the'reclining member 14 to a reclining position. 'as'jdescribediand as shown inmy aforementioned Pent-ins pp t i n S r- N 7 3 6.
Generallyindicatedatjflg is a frictional resistance adjusting means as disclosed in 'copending application No,57 2,l346;,. whic rds" a variable friction resist'ance to movement at the pivotal connection between the actuating link 36 and crank arm 32. An arm 76 which is pivotally mounted on the same pivot which connects link 36 to crank arm 32, is disposed adjacent an opposite surface of the crank arm. As best seen in Fig. 3, the crank arm 32 is disposed between the link 36 and the arm 76.
At the upper end of the arm 76 is an aperture 78 which corresponds with a similar aperture 80 in link 36 with screw 82 passing through these apertures. A spring biasing device in the form of a spiral spring 84 is disposed co-axially about the screw 82. The inner end of spring 84 bears against the surface of link 36 while the opposite end bears against a washer 86 which in turn bears against a butterfly nut 88 in threaded engagement with the screw. By adjusting the position of the butterfly nut the pressure of the springs can be adjusted controlling the friction exerted by arm 62 and link 36 on crank arm 30.
The adjustable ottoman bracket 72, as best seen in Fig. 4, has a flange 90 cooperating with a similar flange on the linkage at the other side of the chair for supporting an ottoman. A leg 92 integral with and normal to the flange 90 has two ears 94 and 96 which form a recess 98 therebetween. Ear 94 is disposed intermediate the leg 92 and is pivoted at 100 to the supporting link 48 intermediate the length thereof, while ear 96 is disposed at one end of the bracket. Projecting from the outer surface of ear 96 is a stop 102 and projecting from the inner surface of the leg 92 approximately intermediate the pivot the ottoman, a front panel, stop 106 striking against crank arm 32 and stop 102 against lever 58, as best shown in Fig. 1. On opposite ends of supporting link 48 are located stops 108 and 110. Although recess 98 accommodates stops 110 when the bracket is in retracted position in front of the chair, the stops 108 and 110 are free from contact with the bracket. Upon movement of the operating linkage, stop 110 on supporting link 48 moves into engagement with the recess 98 formed by the ears 94 and 96. Upon continued movement of the chair from a retracted position to an extended position, the ottoman bracket is freed from its restrained position in front of the chair and is permitted to move about its pivot taking any position between stops 108 and 110 which limit its pivotal movement. This adjustable feature becomes operative almost immediately upon the movement of the operating linkage from its retracted position and is available whether the operating linkage is fully extended or only partially so. When retracted, stops 102 and 106 secure the ottoman bracket in a fixed, vertical position.
The foregoing description is one embodiment of the invention and it will become apparent to those skilled in the art that various changes and modifications may be made therein without departing from the scope of the invention.
