Gains: ii-1 1 My, invention relates to an article of furniture, and 'mo reparticularly to a. reclining articl of furniture, wherein the back-rest and seat form movable 'inemb ers, of a polygonal link-system swingably mounted ona support of connected side frames, and wherein the movements of the members of said polygonal link-system are positively controlled by a guiding link pivote'd'to the support and operatively connectedwith a memberof the polygonal link-system.

An object 'of'rny invention is to provide a convenient controlling mechanism for a leg-rest swingably mounted on the seat of a reclining article. of furniture of above described, type, by means of which the angle between the leg-rest and the seat is automatically altered when the movable members of the reclining article of furniture including the, back-rest andthe seat are brought from a certain position, such as the sitting position, into another position, such as. a reclined position, or vice versa.

Another object of my invention is to improve on, reclining articles, of furniture of above described type as now ordinarilymade.

The above mentioned objects and advantages as, wel1 as other objects and advantages will be more fully disclosed in the following specification, referencebeing had to the accompanying drawings, forming part of this specification, wherein: Fig 1 is a sideelevational view of an adjustable reclining chair according to the invention,a, portion of. the, support being broken away for a better illustration of the mechanism,

A leg-rest 56 is pivoted to the front portion of the seat 32 at 58. According to the invention, the movements of said leg-rest 56 are controlled by a controlling link 68, one end of which is pivoted to the leg-rest at 62, and the other end of which is pivoted to an intermediate point of the guiding link 52 at 64. Said controlling link 68 passes through a recess 66 of the front wall 28 of the support.

The sitting position of the movable members of the chair shown in full lines is limited by the upper edge 68 of the support, on which the seat comes to a rest.

When the occupant of the chair leans the weight of his body against the back-rest, he may readily swing the movable members of the chair into a reclined position, for example into the extreme reclined position shown in dash and dot lines in Fig. 1. As mentioned above, during such '4 in Fig. 4 is pivoted to the pivotal connection I46 between the guiding link I52 and a connecting link of the quadrilateral link-system.

The sitting position of the movable members of the chair shown in Fig. 4 is limited by the upper edge I68 of the front Wall I28 of the support, and the extreme reclined position is limited by the edge I of a recess in the rear wall E26 of the support.

The operation of the chair shown in Fig. 4 substantially corresponds to the operation of the chair shown in Fig. 1, the movements of the members of the quadrilateral link-system and of a movement the guiding link 52 controls the movements of the

members

32, 38, 49, 44 of the quadrilateral link-system and the movements of .18, forming a part of the support 20.

The movable members of the chair may be held in any desired position by means of a locking device generally indicated by I2. As best shown in Figs. 1 and 3, said locking device comprises a rod I4 pivoted to the seat 32 at I6. A bolt 18 having a head 80 and a threaded end 82 is inserted into bores 84 of a clamping sleeve 88 engaged with said rod I4.

The bolt 18 has a projection 88, which is in engagement with a recess of the clamping sleeve 86 so as to prevent the bolt 18 from rotation. A tubular member 90 inserted into a hole 92 of the side wall 22 of the support 20 isarranged between the clamping sleeve 86 and a locking knob 94 screwed on the threaded end 82 of the bolt 18. When said locking knob 94 is loosened, the rod '|4 may freely slide in the clamping sleeve 86, so

that the movable members of the chair may be readily moved from one position into another one. If the'locking knob 94 is tightened, the tubular member 90 and the head 89 of the bolt 18 press against the clamping sleeve 86, whereby the latter is tightly pressed against the rod I4, so that the movable members of the chair are held in the adjusted position.

In the embodiment of an adjustable reclining chair shown in Fig. 4, the quadrilateral linksystem is formed by the extension I38 of the back-rest I34, the lower connecting link I49, the front connecting link I44 and the seat I 32. Said quadrilateral link-system is pivoted to the support I28 at I36 and the movements of its members are again controlled by a guiding link I52. The upper end of said guiding link isswingably mounted on a transverse rod I54 carried by the support, and the lower end of said guiding link is pivoted to the pivotal connection I48 between the lower connecting link I40 and front connecting link I44. Said guiding link I52 also controls the movements of the leg-rest I56 pivoted to the seat at I58 through the medium of the controlling link I60, one end of which is pivoted to the leg-rest at I62. In contrast to Fig. 1, however, the other end of the controlling link I69 shown the leg-rest being controlled by the guiding link I52.

In the embodiment of an adjustable reclining chair shown in Fig. 5, 220 generally indicates a support comprising the side frames 222 and 224 connected with each other by transverse rods 228 and 228. If desired, the support 228 may be made of an integral piece of tubular material.

The seat 232 is pivoted to the back-rest 234 at 236, and the back-rest has an extension 238 projecting downwardly from said pivot 236. On each side of the chair, one end of the lower connecting link 248 is pivoted to the extension 238 of the back-rest at 242. The other end of each lower connecting link 248 is pivoted at 245 to an intermediate connecting link 296 representing a portion of a guiding link 252 pivoted to the support at 254. Furthermore, on each side of the chair, the upper end of a front connecting link 244 is pivoted to the seat at 248, and the lower end of said front connecting link 244 is pivoted to said intermediate connecting link'296 at 241. Thus, the pivotally interconnected downward extension 238 of the back-rest, the link-chain composed of the lower connecting link 248, of the intermediate connecting link 296 and of the front connecting link 244, and the seat 232 form a polygonal link-system in the shape of a quinquelateral link-system which is swingably mounted on the support 229 at the pivotal connection 236 between the back-rest and the seat. The movements of said quinquelateral link-system are controlled by said guiding link 252 pivoted to the support at 254 and including the intermediate connecting link 298 of the link-chain as mentioned above. It is to be understood, that, if

desired, the guiding link and the intermediate connecting link could be made of two separate members which are rigidly connected with each other by screws or the like.

On each side of the chair, one end of a controlling link 260 is pivoted at 262 to a leg-rest 256 pivoted to the seat 232 at 258. The other end of each controlling link 268 is pivoted at 265 to an element 298, which may be considered an extension of the guiding link 252 projecting outside the quinquelateral link-system. According to Fig. 5 the extension 298'is integral with the guiding link 252 a portion of which represents the intermediate connecting link 296, but of course the extension 298 and the guiding link 252 could be made of two separate members rigidly connected with each other by screws or the like. Furthermore, the extension 298 must not necessarily be in alignment with the guiding link 252 as shown in Fig. 5, if desired, the extension 293 fcould be attached to an intermediate point of the guiding link and could project sidewise therefrom. V

As will be readily understood from the statements above, the guiding link 252 controls the movements of the members of the quinquelatdash and dot lines.

erallink-system and the movements, of the-leg;- rest. When. the. back-restis swung about, the pivot 236-. thesmembers of the chair shown-in full linethe sitting positionmay be brought into a, reclined position, for example: into the extreme reclined positionshown indash and dot lines.

The-sitting. -p0siti0n is limited by a stop 258 and the extreme reclined position is limited by a stop 210-. Both; stops are mounted on the support. 22 3 for abutting cooperation with the extension 238 of the back-rest orthe back-rest 234. respectivein.

Figs. 6 illustrates an arm-chair, wherein 328 generally indicates the support comprising side .frames 322 and324 connected with each otherby -transverse. bars 32:1 and. 329, The side frames include the armrrests 33B. Ifhe seat 3321 is pivoted. to the back-rest 334' at 336. The pivotally'interconnected. downward extension 3-33 of the back-rest. 334, the link-chain composed of the lower connecting. link 34!)- and of the front connecting link 3'34 .and'the seat 322 form a quadrilateral link-system swingably mounted on the support 321]- at 336 The movements of said quadrilateral link-system are controlled by the guiding link 3552., the upper end of which is pivoted to a member '32l' of the support 323 at 354 and. the lower portion of. which is pivoted to the lower connecting link 349 at 343. Said guiding link 3552 has an extension 398- projecting outside the quadrilateral link-system. One end of the controlling link 3% is pivoted to saidextension 3.98 of the. guiding link at the. other end of said controlling link 36!) is pivoted at 332 to the leg rest 3'56 pivoted to the front portion of the seat 332z'at 358.

If the movable members of the chair are pivotally connected with each other as described above, and if, for example, the back-rest 334 is swung backwards, the movable members of the chair may be brought from the sitting position shown in full lines into a reclined. position, for example the extreme reclined position shown in In said extreme reclined position limited by a step 370 mounted on the support for cooperation with the seat, the backrest, the. seat and the leg-rest are in the positions indicated by 334', 332', 356.

The movable members of the chair may be held in any desired position by means of a locking device generally indicated by 312 of a construction shown in Fig. 3.

The extension 338 of the back-rest, the lower connecting link 340, the front connecting link 3, the guiding link 352 and its extension 398 as well as the controlling link 363 are provided with series of holes 380, so that the pivots or pins 342, 343, 346, 354, 355 may be inserted into various selected holes for a change in the ef- .fective length of the various members of the chair resulting in a change in the angular movements of'the various members of the chair.

Furthermore, if for example the movable members of the chair are held in the extreme reclined position by means of the locking device 312, thepivot 335 may be disengaged from the extension 398 of the guiding link and the controlling link 36!), whereupon the leg-rest 356 may be swung by hand into the position 356 in align- 4 I ment with the seat being in the position 332. When the leg-rest is in said position 356", the hole at the right-hand end of the series of holes of the controlling link 360 is in register with a hole of the support, so that the pin 1335" may be 15 inserted into said registeringholes,whereby the leg-rest is held in said position. 356".

As shown in Fig.6, a stop 36'! mounted on the seat. 332 projects from the front end of the lattor. for cooperation with the leg-rest 353; when theleg-rest isin the; position 356" in. line with the seat beingin the reclined position 332 the leg-rest abuts against said stop then being in the position 36?". Said stop 33! prevents; an accidental overturning of the leg-rest over itsalignment with the seat when. the seatis under the load of an occupant, the locking device 312 is loosened, and the pin 365" is not yet removed from thehole of the support.

Moreover, if the members of the chair are in the full-line sitting position andif after a loosens ing of the locking device 312 either the. pin 342 or the pin 3461is removed, the seat 332 will drop into a. horizontal position 3323'" limited by a stop 3H2. mounted on the m m er. 321. o he support 320.. Now, the back-rest 3,3 4 may be freely swung into the horizontal position 33% limited by the transverse member 32? and in line with the horizontal position of the seat. After disengaging the pin 365 from the exten- 510m 398 of the guiding link and the controlling link 363. the leg-rest may be freely swung into the horizontal position 356" in alignment with thev horizontal position of the seat. When the leg-rest is in, said position 356', the hole at the left-handv end of the series of holes of the controlling link 3653 is in register with a hole of the support, sov that the pin 33.5" may be inserted into said registering holes, whereby the leg-rest is held in said horizontal position 355". Thus, the arm-chair shown in Fig. 6 may be readily converted into a. bed-like article of furniture.

If desired, the controlling link 3% may also be made in the shape, of a telescopic element having two members slidably and adjustably connected with each other for an adjustment of the length of the controlling link.

Fig. 7 illustrates an arm-chair, wherein the controlling mechanism operates substantially according to the same principle as the controlling mechanism shown in Fig. 6. According to Fig. '7, however, the quadrilateral link-system 43.3, M8, 444, 432 is pivoted to the support 420 at 531, and said pivotal connection 33? does not coincide with the pivotal connection 33 between the seat #332 and the back-rest 833. Furthermore, according to Fig. '7, the extension 438, the lower connecting link 4 38, the front connecting link 444, the guiding link 4'32 and the controlling link 4353 are arranged in the center of the chair, while according to Fig. 6, said elements are. arranged on each side of the chair. The leg-rest 455 is pivoted to the seat 432 at 658. Instead of the connection between the leg-rest and the seat shown in Fig. '7, the leg-rest 356 may be connected with the seat 432 in the manner, shown in Fig. 9. According to Fig. 9, the frame of the seat 332 is provided with a slot 433 receiving the element 435 pivoted to the frame of the seat at 459 and secured to the leg-rest 456 by screws 56%. The construction shown in Fig. 9 permits the arrangement of the pivot 459 at the highest point possible and eliminates an interfering of the element 335 with a cover to be placed around the frame of the seat 532.

Fig. 8 diagrammatically illustrates a controlling mechanism which is somewhat similar to the mechanism shown in Fig. 7, wherein, howlink and the support is in aplane above the seat 7. 532. Therefore, the mechanism shown in Fig. 8 requires the arrangement of a guiding link 552 on each side of the chair. Said two guiding links 552 and their extensions 598 are connected with each other by

transverse rods

543 and 565. The transverse rod 543 is rotatable in a hole of a single lower connecting link 548 arranged in the center of the chair. One end of said lower connecting link 548 is pivoted at 542 to the extension 538 of the back-rest 534, and the other end of said lower connecting link is pivoted at 546 to one end of the front connecting link 544, the other end of which is swingable on a transverse rod 548 of the seat 582. One end of a single controlling link 588 is swingably mounted on the transverse rod 585, while the other end of said controlling link 568 is swingably mounted on a transverse rod 562 of the leg-rest 556.

In the embodiment of a chair shown in Fig. 10, 832 indicates the seat pivoted to the back-rest 634 at 636. Similar to the embodiment shown in Fig. 5, the pivotally interconnected extension 638 of the back-rest, the lower connecting link 549, the intermediate connecting link 696, the front connecting link 344 and the seat 832 form a quinquelateral link-system swingably mounted on the support 528 at 636. On each side of the chair, the upper end of each guiding link 852 is pivoted to the support at the point 654 above the level of the seat. The lower portion of each guiding link 652 is rigidly connected with the intermediate connecting link 89 6. According to said Fig. 10, on each side of the chair each controlling link 668 is pivoted to an intermediate point of the guiding link 652 at 664. The other end of each controlling link 868 is pivoted at 882 to the leg-rest 656 pivoted to the seat at 858. Again, the guiding links 652 control the movements of the members of the quinquelateral link-system and of the leg-rest. The sitting position of the members of the chair shown in full lines is limited by the stop 668 mounted on the support and the extreme reclined position of the members of the chair shown in dash and dot lines is limited by the stop 618 mounted on the support.

The adjustable reclining chair shown in Fig. 11 is similar to the chair shown in Fig. 10, with the exception, however, that the seat 732 is not pivotally connected with the back-rest I34. According to Fig. 11, the back-rest 134 having a downward extension I38 is pivoted to the support 728 at 136, and the seat 132 is pivoted to the support at 194. The pivots I38 and I84 are arranged at a small distance from each other. Thus, the pivotally interconnected movable extension 138 of the back-rest, the movable lower connecting link 148, the movable intermediate connecting link I96, the movable front connecting link I44, the movable seat 132, and the stationary portion of the support 129 between the pivots I84 and 'i38 from the members of a hexagonal link-system. The guiding link I52 pivoted to the support 128 at 154 and rigidly connected with intermediate connecting link E98 serves to control the movements of the movable members of said hexagonal link-system. Furthermore, said guiding link 752 controls the movements of the leg-rest F56 pivoted to the seat 13?. at 158 through the medium of the controlling link 188, the ends of which are pivotally connected with said leg-rest and an intermediate point of said guiding link.

According to the embodiment of a chair shown in Fig. 12, the back-rest 834 is pivoted to the support 828 at 836 at a point spaced from the pivotal connection 884 between the rear end of the seat 832 and the support. Adjacent ends of the lower connecting link 848 and the front connecting link 844 are pivotally connected with each other at 846. The rear end of the lower connecting link 848 is pivoted to the downward extension 838 of the back-rest 834 at 842, and the upper end of the front connecting link 844 is pivoted to the seat 832 at 848. Thus, the pivotally interconnected movable extension 838 of the back-rest, the movable lower connecting link 848, the movable front connecting link 844, the movable seat 832, and the stationary portion of the support 828 between the pivots 884 and 836 form the members of a quinquelateral link-system. The guiding link 852 pivoted to the support 828 at 854 and pivoted to the lower connecting link 848 at 843 controls the "move ments of the movable members of said quinquelateral link-system. The extension 898 of the guiding link is pivoted to said guiding link at 843 and, thus, is swingable relative to the main body 852 of said guiding link. As shown in Figs. 12 and 13, the main body of said guiding link is provided with a cam-like lug 886 arranged for engagement with said swingable extension 898, so that the latter may be held in alignment with the main body 852 of the guiding link during a swinging movement of said main body about the pivot 854. One end of the controlling link 868 is pivoted to the extension 898 of the guiding link at 865, the other end of said controlling link is pivoted at 862 to the leg-rest 858 swingably mounted on the seat 832 at 858. When the members of the chair are in the position shown in full lines in Fig. 12, the back-rest, seat, and legrest may be brought into a reclined position, for example the extreme reclined

position

834, 832, 856' shown in dash and dot lines, by swinging the back-rest about its pivot.

The movable members of the chair may be held in any desired position by means of a locking device 812 of the type shown in Figs. 1 and 3.

As mentioned above, the extension 898 of the guiding link is swingable about'the pivot 843. Furthermore, said extension 898 is provided with 2. lug 888 as shown in Figs. 12 and 13. If the back-rest and seat are held in a predetermined position, for example the sitting position shown 'in. full lines in Fig. 12, by means of the locking device 832, the leg-rest 658 may be swung by hand about its pivot 858 into the position 856", wherein, theswingable extension 898 being in the position 898" is in alignment with the controlling link being in the position 858". Now, when a slight pressure is exerted on the leg-rest, for example by the legs of the occupant resting in the chair, the extension 898 and the controlling link 888 are moved slightly beyond said straight line, until the lug 888 of the extension abuts against the controlling link, whereby said elements are locked and held in a predetermined position relative to each other. Now, the extension 688 acts as a part of the controlling link which now may be considered as being pivoted to the guiding link 8 52 at 843. Thus, upon loosening the locking device 8'i2,'the back-rest, seat, and leg-rest may be brought from the

position

834, 832, 8567 into a reclined position by swinging the back-rest about its pivot 838; under such circumstances, the extreme reclined position is obtained, when the leg-rest is in alignment with the seat. a i T 998 isarranged within' the polygonal I link-system which may be of the type shown-in any of the above desoribed 'Figs. 1, 4-8; or -1-2. On'e:end of the controlling element n 998 is pivoted to the gui'ding link 9521 at 999, the upper end of which is -p'iveted to =the support -(not shown) at 954 and the lower end of which'is' pivoted at 943 110 the lowerconnecting link 94!]. 'The other-end of the controlling element- 898 is pivoted "to one end-of the-controlling link 95G at 9B5,-the other :end of which is-pivoted at 962 to the-leg rest955 swingably mounted on the seat 932.
