8 Claims. (Cl. 15 106) The present invention relates generally to reclining chairs, and in particular to an improved reclining chair including a body-supporting unit having a seat and back rest and a leg-rest coordinated for movement with the body-supporting unit.

The well known reclining chair comprises a support and a body-supporting unit including a back-rest and seat pivotally mounted on the support. The body-supporting unit may include a rigid seat and back-rest which moves together as the chair occupant leans against the back-rest, or may include a body-supporting unit having a seat and back-rest mounted respectively for inclining and reclining movement in a prescribed relationship under the control of the seat occupant. Such chairs usually incorporate a leg-rest which is mounted for coordinated movement to an elevated leg-supporting position as a function of or in response to the reclining movement.

It is an object of the present invention to provide an improved reclining chair of the aforesaid general construction. Specifically, it is within the contemplation of the invention to provide a reclining chair which is particularly suited to be manufactured at a relatively low cost, yet achieves the requisite coordinated movement of the several components of the chair. Advantageously, such chairs are suited to find widespread application in the medium and low price fields, particularly for use as outdoor furniture.

In accordance with an illustrative embodiment demonstrating features and advantages of the present invention there is provided a reclining chair which comprises a support and a body-supporting unit including a back-rest and seat pivotally mounted on the support. The seat is movable into a prescribed inclined position with its forward end elevated in response to pivotal movement of the backrest into a prescribed reclining position, either as a result of being integral with the back-rest or being coordinated for inclining movement relative. to the back-rest. A leg-rest is provided for the chair With means which pivotally mount the leg-rest; on the support which includes a double-arm lever pivoted onthe support and having one arm connected to the leg-rest, and linkage means which eperatively connect the; leg-rest to the back-rest for moving thev leg-rest to various leg-supporting positions in response to movementof the back-rest to various reclined positions. The linkage means, is constructed and arranged to bring, the leg-rest to an elevated position substantially at the level of the elevated forward end of the seat in response to movement of the back-restinto a prescribed reclining; position and the-.corresponding"movement of the seat into an inclined-position.

The above brief description, as well as furtherobjects,

features and advantages'of the present invention will be best, appreciated by reference'to the following detailed description of presently preferred, but illustrative, embodiments, when taken in conjunctionwith the accomwith the dotted lines showing the chair in its reclining position;

Fig. 2 is a side elevational view of a further embodiment of reclining chair demonstrating features of the present invention, with the dotted lines showing the chair in the reclining position;

Fig. 3 is a side elevational view of a still further embodiment of reclining chair embodying features of the present invention, with the dotted line showing thev chair in a reclining position; and,

Fig. 4 is a side elevational View of a still further embodiment of reclining chair demonstrating features of the invention, with the dotted line showing the chair in the reclining position.

Referring. now specifically to Fig. l of the drawings, there is shown an improved reclining chair according to the present invention, wihch includes a support generally designated by the reference numeral 10. The support includes two U-shaped tubular frame members 12, 14 which are arranged in criss-cross relationship relative to each other, with the bight sections of the frame in contact with the floor and with the legs extending across each other and rigidly connected to each other by appropriate means, such as the pins or bolts 16. In this embodiment a rigid body-supporting unit including a back-rest 18 and a seat 32 is swingably mounted on the support 10 at a main pivot 20 located at the juncture between the backrest 18 and the seat 32 for pivotal movement from the upright or sitting position illustrated in Fig. 1 by thev full lines to the tilted reclining position illustrated by the broken lines.

At each side of the chair, there is provided a leg-rest supporting and controlling linkage which mounts the legrest 34 for movement into various elevated leg-supporting positions in the response to movement of the back-rest 18 to various reclining positions. The leg-rest supporting and control linkage includes a double-arm lever 22 which is pivotal-1y supported on the frame member 14 of the support 10 intermediate its ends at a pivot 28 to thereby provide a first arm extending upwardly from the pivot 28 and a second arm extending downwardly from the. pivot 28. The upwardly extending arm of the double-arm lever 22 is connected to the back-rest 18 by a connecting link 24 which has its forward end connected to the double-arm lever 22 at the pivotal connection 26 and. has its rearward end connected to the back-rest 18 at the pivotal connection 30. The leg-rest 34 is rigidly connected to the downwardly extending arm of the double-arm lever 28 so as to participate in the movements of the lever. 22. The legrest 34 may be rigidly connected by screws or the like or may be integral withv the lever 22, as shown in the drawings. As may be appreciated by inspecting Fig. 1', the stationary pivot 28 of the double-arm lever on the support is disposed at a location above the plane of the seat 32 when the seat isin the sitting position. The further pivotal connection 30' at the rear end. of the connecting link 24 to the back-rest 18 is at a point spaced above the main pivot or mount 20 of the body-supporting unit on the support it). The upwardly extending arm of the doublearm. lever 22 intermediate the

pivots

28, 26, the connecting link 24, and a portion of the body-supporting unit intermediate the pivots 30 and 20 serve as movable links of the controllinglinkage, with the portion of the support 10 intermediate the pivots 20, 23 serving as the stationary link of the controlling linkage. This linkage is constructed and arranged to bring the'leg-rest 34 into an elevated position substantially at the level ofthe elevated forward end of the seat in response to movement of the back-rest 18 into the prescribed reclining position and the corresponding movement of the seat into the prescribed inclined position. By separately mounting the leg-rest on the sup port and the proper coordination of its movement, the legrest may be brought into the required elevated leg supporting position as a function of the reclining movement of the body-supporting unit in a relative simple manner and with a relatively inexpensive linkage.

In order to establish the sitting position of the bodysupporting unit, a stop 36 is fixed to the frame member 14 in a position to underlie and abut the undersurface of the seat 32 when the latter is in the sitting position. The arrangement of the leg-rest controlling linkage 22, 24 is such as to achieve a self-locking action as the link 22, 24 moves into a substantially in-line position thereby establishing the extreme reclining position of the body supporting unit. I

In use, the chair occupant is seated in the chair when the body-supporting unit is in the upright sitting position and upon leaning against the back-rest, the body-supporting unit is brought into the reclined position illustrated by the broken lines. Simultaneously the leg-rest supporting and controlling linkage is effective to elevate the leg-rest 34 to a position extending forwardly of and substantially at the level of the elevated forward end of the seat 32, with the fully reclined position being established by the self-locking feature of the leg-rest supporting and controlling linkage.

Referring now specifically to Fig. 2 of the drawings, there is shown a further embodiment of reclining chair according to the present invention, which includes a support generally designated by the reference numeral 110. In this embodiment, a rigid body supporting unit including a back-rest 118, a seat 132 and a downward extension 138 is swingably mounted on the support 110 at a main pivot 140 on the downward extension 138. As before, the body-supporting unit is mounted for pivotal movement from the sitting position illustrated in Fig. 2 by the full lines to the reclining position illustrated by the broken lines.

At each side of the chair there is provided a leg-rest supporting and controlling linkage which mounts the legrest 134 for movement into various elevated leg-supporting positions in response to movement of the back-rest 118 to various reclining positions. The leg-rest supporting and controlling linkage includes a double-arm lever 122 which is pivotally supported on the support 110 intermediate its ends at a stationary pivot 128 to thereby provide a first arm extending upwardly from the pivot 128 and a second arm extending downwardly from the pivot 128. The upwardly extending arm of the double-arm lever 122 is connected to the back-rest 118 by a connecting link 124 which has its forward end connected to the doublearm lever at the pivotal connection 126 and has its rearward end connected to the back-rest 118 at the pivotal connection 130. The leg-rest 134 is rigidly connected to the downwardly extending arm of the double-arm lever 128 so as to participate in the movements of the lever 122. The leg rest 134 may be rigidly connected by screws or the like with the lever or may be integral with the latter as shown in the drawings. As may be appreciated by inspecting Fig. 2, the stationary pivot 128 of the doublearm lever 122 on the support is disposed at a location above the plane of the seat 132 when the seat is in the sitting position. The pivotal connection 130 at the rear end of the connecting link 124 to the back-rest 118 is at a point spaced above the main pivot or mount 120 of the body-supporting unit on the support 110. The upwardly extending arm of the double-arm 122 lever intermediate the

pivot

128, 126, the connecting link 124, and

the portion of the body-supporting unit intermediate the pivots 130 and 120 serves as movable links of the controlling linkage, with the portion of the support 110 intermediate the pivot 120, 128 serving as the stationary link prescribed reclining position.

In order to establish the sitting position of the bodysupporting unit, a stop 142 is fixed to the support in a position to abut the extension 138 when the seat is substantially horizontal. The arrangement of the legrest controlling linkage 122, 124 is such as to achieve a self-locking action as the link 122, 124 moves into a substantially in-line position to thereby establish the extreme reclining position of the body supporting unit.

Referring now specifically to Figure 3, there is shown a further reclining chair according to the present invention which includes a support generally designated by the reference numeral 210 made up of appropriate tubular members bent to provide a frame. In this embodiment, the body-supporting unit includes a back-rest 218 and a seat 232 mounted on the support for reclining and inclining movement respectively. Specifically, the back-rest is pivoted at its lower end at a back-rest pivot 220 on the support 210 and the seat 232 is pivoted on the back-rest 218 at a seat pivot 244 spaced above the back-rest pivot 220. Appropriate seat control means are provided for cordinating the inclining movement of the seat to the reclining movement of the back-rest. In this embodiment, the seat control means is in the form of a cam follower 246 which is fixed to and depends from the under-surface of the seat 232 and is in engagement with a camming element 248 formed by providing a substantially upstanding extension on the frame 210.

At each side of the chair there is provided a leg-rest supporting and controlling linkage which mounts the legrest 234 for movement into various elevated leg-supporting positions in response to movement of the backrest to various reclining positions. The leg-rest supporting and controlling linkage includes a double arm lever 222 which is pivotally supported on the support 210 intermediate its ends at a stationary pivot 228 to thereby provide a first arm extending upwardly from the pivot 228 and a second arm extending downwardly from the pivot 228. The upwardly extending arm of the double arm lever 222 is connected to the back-rest 218 by a connecting link 224 which has its forward end connected to the double arm lever 222 at the pivotal connection 226 and has its rearward end connected to the back-rest 218 at the pivotal connection 230. The leg-rest 234 is rigidly connected to the downwardly extending arm of the double-arm lever 222 so as to participate in the movements of the lever 222. As may be appreciated by inspecting Fig. 3, the stationary pivot 228 or the doublearm lever 222 on the support 210 is disposed at a location above the plane of the seat 232 when the seat is in the sitting position. Further the pivotal connection 230 at the rear end of the connecting link 224 to the backrest 218 is at a point spaced above the back-rest pivot or mount 220 of the body-supporting means. The upwardlyextending arm of the double arm lever 222 intermediate the

pivot

228, 226, the connecting link 224 and a portion of the back-rest intermediate the

pivots

230 and 220 serve as movable links of the controlling linkage, with the portion of the support 10 intermediate the

pivot

220, 228 serving as the stationary link of the controlling linkage. This linkage is constructed to bring the leg-rest 234 into an elevated position substantially at the level of the elevated forward end of the seat when the latter is inclined via the seat control means 246, 248 in response to movement of the backrest 18.

Referring now specifically to Figure 4, there is shown a further reclining chair according to the present invention which includes a support generally designated by the reference numeral 310, made up of appropriate tubular members bent to provide a frame. In this embodiment, the body-supporting unit includes a back-rest 318 and a seat 332 mounted on the support 310 for reclining and inclining movement respectively. Specifically, the back-rest is pivoted at its lower end at a backrest pivot 320 on the support 310 and the seat 332 is pivoted on the back-rest 318 at a seat pivot 34.4 spaced ing positions in response to movement of the back-rest .to. various reclining positions. The leg-rest supporting and controlling linkage includes a double-arm lever 322 which is pivotally supported on the support 310 intermediate its ends at a stationary pivot'328 to thereby provide a first arm extending upwardly from the pivot 328 and a second arm extending downwardly from the pivot 328. The upwardly extending arm of the double-arm lever 322 is. connected to theback-rest 318 by a connecting link 324 which has its forward end connected to the double-arm lever at the pivotal connection 326 and has its, rearward end connected to the back-rest 318 at the pivotal connection 336. The leg-rest 334 is rigidly connected to the downwardly extending arm of the double arm lever 323 so as to participate in the movements of the lever 322. As may. be appreciated by inspecting Fig. 4, the stationary pivot 328 or the double-arm lever 322 on the support 310 is disposed at a location above the plane of the seat 332 when the seat is in the sitting position. Further the pivotal connection 330 at the rear end, of the connecting links 324 to the back-rest 318 is. ata point spaced above the main pivot or mount 320 of the back-rest. The upwardly extending arm of the double-arm lever intermediate the
