ARTICLE OF REPOSE FOR SUPPORTING THE BODY OF A PERSON Anton Lorenz, Boynton Beach, Fla.

Application November 5, 1954, Serial No. 466,994

8 Claims. (or. 155-106 repose of above described type wherein the movements or the movable members of the article from one position into another may be obtained with ease.

Another object of the invention is to improve on the construction of articles of repose as now customarily made. 1

Other objects and structural details of the invention will be apparent from. the following description when read in conjunction with the accompanying drawings forming part of this specification, wherein:

Fig. 1 is a side elevational view of a reclining arm chair according to the invention, a portion of a side wall of the frame being broken away,

Fig. 2 is. a side elevational view of another embodiment of a reclining armchair according to the invention,

a portion of aside wall of the frame being broken away,

Fig. 3 is a side elevational view of still another embodiment of a reclining armchair according to the invention, a portion of a. side wall of the frame being broken away, and

Fig-4 is a side elevational view of a further embodiment of a reclining armchair according to the invention, a portion of a side wall of the frame being broken away.

Referring now to Fig. 1, 10 generally indicates a support or base comprising

side walls

12 and 14 connected with each other in any suitable manner.

A back-rest 16. swingably mounted" on the support 10 at 18. has a downward extension. 20 rigid herewith.

A seat 22 is swingably mounted on the support 10 at 18 in coaxial alignment with the pivotal connection of the back-rest 16 with the support 10.

: There is a first pair of

links

24, 26 pivotally jointed at 28. Furthermore there is a second pair of links 30, 3.2 pivotally jointed at 34. Said first and second pairs of links are pivotally connected with each other at 36 of the type of lazy tongs A rear arm 40 of said

lazy tongs

24, 26, 30, 32 is pivoted to the seat 22 at 42. The other rear arm 44 of said

lazy tongs

24, 26, 30, 32 is pivoted at 46 to thelower end of an arm 48 swingably mounted on the support 10 at 50.

One endof a link 52 is pivoted to an intermediate point of said arm 48 at 54. The other end of said link 52 is pivoted to the downward extension 20 of the back-rest 16 at 56.

A leg-rest 58 is swingably mounted on the front arm 60 of the

lazy tongs

24, 26, 30, 32 at 62. Furthermore, said leg-rest 58' is pivoted at 64 to one end of a controlling link 66, the other end of which is pivoted to the other frontarm 68 of the

lazy tongs

24, 26, 30, 32' at 70.

"ice

Thus, when the back-rest 16 is swung about its pivot 18 Item the sitting position, snown in tull lines, into the reclined position to, snown in dash-and-dot lines, the seat 22 and the leg-rest :6 are brought rrom their sitting position, shown in run lines, mto tne reclined position 22' and 515, shown in dash-and-dot lines, by the mechanism described above. It will be noted that the

lazy tongs

24, 26, 3'0, 32 propel the leg-rest 58 forwardly and that the latter is swung simultaneously about its pivot 62 by the controlling link 66.

According to the embodiment shown in Fig. 2, again the back-rest 116 and seat 122 are swingably mounted on the support at 118.. Furthermore, again a rear arm of the

lazy tongs

124, 126, 130, 132 is pivoted to the seat 122 at 142. Moreover, again the leg-rest 158 is pivoted to the front arm 160 of the

lazy tongs

124, 126, 130, 132 at 162 and a controlling link 166 is pivoted to said leg-rest 158 and the other front arm 168 of the

lazy tongs

124, 126, 130, 132 at 164 and 170 respectively. 0

However, the rear arm 144 of the

lazy tongs

124, 126, 130,132 is pivoted at 157 to the downward extension 120 of the back-rest 116 and at 155 to an arm 148 swingably mounted on the support 110 at 150.

As will bereadily understood, a swinging movement of the back-rest 116 from its sitting position, shown in full'lines, into a reclined position, shown in. dash-anddot lines, causes a positive displacement of the seat 122 and the leg-rest 158 from their sitting position, shown in full lines, into the position shown in dash-and-dot lines.

According to Fig. 3, a unit 272 comprising a back-rest 216' and a seat 222 rigid with each other is swingably mounted on the. support 210 at 274. Said unit 272 has a downward extension 220 rigid, therewith. V

The rear arm 240 of the lazy tongs comprising the

links

224, 226, 230, 232 pivotally'jointed. with each other ispivoted to the seat portion of the. unit 272. at 242. The other rear am 244 of said

lazy tongs

224, 226, 230, 232 is pivoted at 246 to the arm 248 swingably mounted on the support 210 at 250. Said arm 2.48 ispivoted intermediate its ends at 254 to one end of a link 252, the other end of which is pivoted at 256 to the extension 220 of the unit 272.

A leg-rest 258 swingably mounted on they front arm 260 of the

lazy tongs

224, 226, 230, 232 at 262is-pivoted at 264, to one end of a controlling link. 2.66, thejother end of which is pivoted at 270 to the front arm 268 of the

lazy tongs

224, 226, 230, 232.

When the unit 272 is rocked about its pivot 274 from the sitting position, shown in full lines, into the reclined position,shown in dash-and-dot lines, the leg-rest 258 is propelled forwardly and swung about its pivot 262' by the mechanism described above in dependence on the movements of the unit 272. r

According to Fig. 4, the seat-back rest unit 372 has a downward extension 320 which is rockably mounted on the support 310 at 376.

The rear arm 340 of the lazy tongs 324326.330, 332 is again pivoted on the seat portion 322 of the unit 372 at 342. Furthermore, again the leg-rest 358 being pivoted to the front arm 360 of the

lazy tongs

324, 326, 330, 332 at 362i pivoted to one end ofthe controlling link 366 at 364, the other end of said controlling link 366 being pivoted to thefront arm 368 of the

lazy tongs

324, 326, 336, 332 at 377.

The lower rear arm 344 of the

lazy tongs

324, 326, 330, 332 is pivoted at 346 to one arm 378 of a doublearmed lever 380 swingably mounted on the su port 310 r at 382. The other arm 384 of said double-armed lever 380 is pivoted at 386 to one end of a link v352, the other end of which is pivoted at. 356 to the downward exten sion 320 of the unit 372.

It will be readily understood that the link mechanism described above causes movements of the leg-rest 358 in coordination with rockingmovements of the unit,372. Each ofithe embodiment described above may be equipped with limiting means for limiting the sitting posi: tion and the extreme reclined position of the movable members of the chair. t

, Furthermore, each of the embodiments shown in the drawings may be equipped with locking means for bolding the movable members of the chair ,in any desired position. v, v
