7 Claims. (Cl. 155-106) This invention relates to articles of furniture and more particularly to a leg-rest control arrangement for use in connection with an adjustable article of repose for supporting the body of a person, wherein a support, rockable body supporting means and -a linkage are positively inter-engaged with each other.

An object of the present invention is to provide a leg-rest control arrangement by means of which on one hand the leg-rest is swung upwardly and on the other hand is extended when the seat of the article of repose is moved from the sitting position into a reclined position, so that the supporting portion of the leg-rest in the elevated position of the latter is extended to such a degree that a full support of the legs of a tall person resting on the article of repose is assured.

A further object of the present invention is to provide an extensible leg-rest arrangement which can be collapsed in the sitting position of the leg-rest to such a degree, that the article of repose may be made comparatively low, and which in spite of this collapsible feature permits an extension of the leg-rest during its movement from the sitting position into the elevated position to such an extent that a full support of the legs of the occupant of the article is assured.

Another object of the present invention is to improve on the art of articles of repose for supportingthe body of a person as now customarily made.

Figs. 6 and 7 are diagrammatical ill'ustrations of the 8 link system of a further embodiment of a chair according to the invention, said link system being shown in the sitting position and a reclined position respectively,

- figspS and 9 are diagrammatical illustrations of;a

system of still anotherembodiment of a chair according to the invention, said link system being shown 'i n the. sitting position and a reclined position respectiVlY .1. r j ljFig Lloand lliare diagrammatical illustrations of ward extension 24 (only one being shown) is pivotally connected with the rear end of a lower connecting 26 at 28. Said lower connecting link 26 is pivoted at 30 intermediate its ends with a lower end of a guiding link 32, the upper end of which is swingably mounted on the support 10 at 34. The front end of the lower connecting link 26 is pivoted at 36 to a front connecting link 38, which in turn is swingably mounted on the seat 18 at 40.

The above described constrained linkage provides for coordinated movements of the seat 18 and the back-rest 20 with each other.

The portion of the support between the

pivots

22 and 34 represents the stationary link of the constrained linkage. The movable links of said constrained linkage are formed by the seat 18, back-

rest

20, 24, the lower connecting link 26, the front connecting link 38 and the guiding link 32. v I

A leg-rest 42 is pivotally connected with an extension 44 at 46. Said leg-rest extension 44 has a projection 48 beyond the pivotal connection 46 between the leg-rest 42 and the leg-rest extension 44, whereby a double armed lever is formed. I

The control of the movements of the leg-rest 42 and its extension 44 relative to each other and relative ,to the seat 18 during a movement from the sitting position shown in Fig. 1 and the reclining position shown in Fig. 3 and vice versa is obtained by the following arrangement: The leg-rest 42' is pivoted at spaced

points

50 and 52 to a first bar 54 and a first link 56 respectively. Said first bar 54 crossing an extension 58 of the front connecting link 38 is pivotally connected with said extension 58 at 60. The lower end of said extension 58 of the front connecting link 38 is pivoted to the rear end of the link 56 at 62. A second bar 64 is pivoted to the first bar 54 at 66 and the projection 48 of the leg-rest extension 44 at 68. The rear end of the first bar 54 is pivoted at 70 to the lower end-of an auxiliary connecting link 72, the upper end of which is pivoted to the lower connecting link 26 at 74.

Thus, it will be readily understood that the above' described leg-rest control arrangement is operatively connected with two

movable members

26 and 38 of the constrained .hnk-

age

18, 20, 24, 26, 32, 38, including the seat 18 and the backrest 20. One of said links 72 of the leg-rest control arrangement is pivotally connected with the movable member 26 of the constrained linkage while the other member 58 of said leg-rest control arrangement is rigid with the front connecting link 38 oi the Patented Sept. 20, 1960 constrained linkage. Although, according to the em bodiments shown in Figs. 1-3, the

members

38 and 58 are integral with each other, it will be understood that said 7 members may be separate elements rigidly connected warrant other by screws or the hke. b jWhenthe movable members of the chair are in the sitpos-ition, the extension 44 of theleg-rest 42 is turned rearwardlyfas shown in Figs. 1 and 2. r

When the movable members of the chair are brought the'sitting position shown in Figs. 1 and '2 into the reclined position shown in Fig. 3, the relative movement of the 26 and 38, the

constrained linkage

20, 24, 26,32, 38, to which the above described leg-rest control arrangement is connected, causes. an upward movement of the legrest. 42 and simultaneously therewith a forwardimovement of theextension 44 whereby the latter 7 isfbrought -into alignment with the leg-rest 42 when-the movable members of the chair reach the extreme re- I QH cd position.

According-to the embodiment shown in Figs. 4 and againthe seat 1 18 and back rest. 120 with its downward 7 extension 124 are swingably mounted on the support 110 611,122. Furthermore, again the constrained linkage ineludes a lower connecting link 126, a front connecting 1ink 138. and -a guiding link l32. The rear end of the 'lower connecting link 126 'is pivotedto the downward.

extension 124 of the back-rest 120 at 128. The firont end of the lower connecting link 126 is pivoted to the diront connecting link 138 at 136. The upper end of the front connecting link 138 ispivoted to the front 'end ofthe'seat 118 at 140. The guiding link 132 being swingably mounted on the support 110 at 134 is pivoted toithe lower connecting'link 126 at 130.:

The leg-rest control arrangement includes aleg-rest .142

' .a-ndan extension 144 swingably mountedon the leg-rest 142 at 146. The extension 144 of the leg-rat 142 has a projection beyond the pivotal connection 146 between the leg-rest-142-.a-nd.its extension 144.- A first bar 154 is pivotally connected to the leg-rest 142 at 150. A sec- {and bar 164 is pivoted to said first bar 154 at 166 and to .theprojection 148 of the leg-rest control 144 at 168.

Fmthermore, a link 156 is pivoted to the leg-rest 142 at with the latter at the crossing point160 is pivoted to the 'bar 154 at 162.=Said link 158 is rigid with the front connecting link 138 of the constrained linkage 118, 120,

A movement of the seat 218 and 'hack rest 220 from. the sitting position shown in Fig. 6 into the reclined position shown in Fig. 7 causes positively a displacement of the leg-rest 242 and its extension 244 trom the position shown in Fig. 6 into the position shown in Fig. 7.

The chair shown in Figs. 8 and 9 again comprises the constrained linkage 318, 320-324, 326, '332and 338.
