F'Q/DTJOF A SfA/A/Pl/ACKE HTTOIZIVG'YI United States Patent F 3,115,363 LEGREST @(DNTRQL MEAN FUR MULTIPLE PGSTTIQN RECLWING CHAIR Fridtjof F. Schliephache, Beriinichmargendorf, Germany, assignor to Anton Lorenz, Boynton Eeach, Fin. Filed Apr. 7, 1960, Ser. No. 20,617 11 Claims. (Cl. 297-89) The present invention relates to improvements in ad justable reclining chairs and in particular relates to legrest actuating means for a reclining chair of the multiple position type.

The typical multiple position reclining chair includes a body-supporting unit consisting of a seat and a back-rest formed rigidly with each other, and mounted upon a support frame for rearward movement from an upright sitting position to an intermediate, tilted sitting position and then to a fully-tilted or reclined position. The chair also includes a leg-rest which is mounted for movement from a retracted position beneath the seat to an extended position forwardly of the seat. The leg-rest must be brought to an extended, leg-supporting position when the bodysupporting unit is in its intermediate, tilted sitting position, and maintained in proper leg-supporting position when the unit is brought through various reclined positions to its fully tilted position. The intermediate, tilted sitting position of the body-supporting unit is a slightlytilted active position with the occupants body in a substantially upright attitude suitable for viewing television, talking, reading or the like. In such position, the leg-rest has already moved to an extended position for supporting the occupants out-stretched legs. The bodysupporting unit can then, when desired, be tilted further to an inactive, fully-tilted reclining position in which the occupants body is supported in a more supine or recumbent position for greater relaxation. In this fullytilted position, the leg-rest maintains the optimum extended leg-supporting position and remains substantially in a horizontal position relative to the floor surface.

It is an object of the present invention to previde legrest actuating means for advancing the leg-rest to its extended leg-supporting position rapidly in response to movement of the body-supporting unit to its intermediate, tilted sitting position, and for maintaining the leg-rest in its extended position with a slower rate of movement relative to the forward end of the seat when the unit is further advanced to its fully-tilted position.

A further object of the invention is the provision of leg-rest actuating means for multiple position reclining chairs which includes a connecting link of telescopic construction connecting the leg-rest control means and the seat control means, and so arranged as to permit variance in its over-all length during the chair movement producing a rapid elevation of the leg-rest during a first phase of movement and a slower elevation during a second phase of movement.

In accordance with the present invention, the chair body-supporting unit is mounted on a support frame by a pair of guide links. The rear guide link is mounted on the support frame white the front guide link is mounted on a carrier member which in turn is mounted on the support frame. The carrier member is temporarily maintained in a stationary position during the first motion phase and both guide links pivot rearwardly to guide the 3,115,363 Patented Dec. 24, 1963 body-supporting unit to the intermediate, tilted sitting position. During the second motion phase, the rear guide link is stopped from rearward movement and the seat turns about its pivotal connection with the stationary rear guide link, the carrier member and the front guide link rising with the seat. The leg-rest is actuated by a connecting link which couples the carrier member with the leg-rest control linkage, the connecting link being formed of two telescoping link sections to produce a connecting link of variable length during the first and second motion phase. An actuating link is pivotally mounted on the support frame and connected through the forward link section of the connecting link to the leg-rest control linkage.

Additional objects and advantages of this invention will be apparent during the course of the following specification when taken in connection with the accompanying drawings, in which:

FIG. 1 is a side elevational view, with parts broken away and shown in section, of a reclining chair incorporating the leg-rest actuating means of the present in vention, the chair being shown in an upright sitting position;

FIG. 2 is a similar side elevational view showing the chair of HG. 1 in its intermediate, tilted sitting position with the leg-rest extended in leg-supporting position; and

FIG. 3 is a similar side elevational view showing the chair of FIGS. 1 and 2 in its fully-tilted reclining position.

Referring in detail to the drawings, there is shown therein a reclining chair made in accordance with the invention herein, and generally comprising a support frame 10 and a body-supporting structure 24 movably mounted thereon. The support frame 10 includes a pair of

side frames

12 and 14 connected together in spaced relationship by cross bars or braces 16, 18 and 2th and mounted upon the usual legs 22.

The bodyupporting structure 24 includes a back-rest 26 and a seat 28 formed integrally with each other to provide a rigid seat and back-rest unit. Seat control means are provided to mount the body-supporting unit 24 on the support frame 10 for rearward movement from the upright sitting position of FIG. 1 through a first motion phase to an intermediate, tilted sitting position of FIG. 2, and then through a second motion phase to the fully-tilted reclining position of FIG. 3. Such seat control means includes a rear guide link 30 and a front guide link 32.

The rear guide link 39 is mounted by fixed pivot 34 on the support frame W and is connected by pivot 36 to a bar 33 which is affixed to the seat 28. The front guide link 32, is connected by pivot it? to the bar 38 and therefore to the forward portion of the seat 28, and is mounted by pivot 42 on a carrier member 44 at an intermediate point thereon. One end of the carrier member 44 is mounted by pivot 46 on a bracket 48 which is immovably mounted on cross bar 16 and therefore serves as a rigid portion of the support frame 10.

The chair also includes a leg-rest 5d and a leg-rest supporting linkage designated generally by the reference numeral 52. This leg-rest supporting linkage 52 includes a pair of

links

54 and 56 mounted at spaced points on the forward end of the seat 28 by respective pivots 58 and 6%, and a pair of

links

62 and 64 connected by

respective pivots

66 and 68 to spaced points on the leg-rest St). The end of link 54 is connected by pivot 7 t to the end of link is 62, while the end of link as is connected by pivot '72 to the end of link 64. The link crosses over the link 64 and is connected thereto at its crossing-over point by pivot 74 in order to coordinate movement of the link pairs.

The leg-rest supporting linkage S2 is arranged to guide the leg-rest 5t) for movement between a retracted position beneath the seat, shown in FIG. 1, and the extended legsupporting positions of FIGS. 2 and 3. Actuating means are also provided to impart movement to the leg-rest in response to movement of the body-supporting unit 24. Such actuating means includes a pair of connecting links 89 and 82 and an actuating link $4, and also includes the carrier member 44.

The connecting link 8% is connected by pivot 86 to the lower end of the carrier member 4-4, while the other connecting link 82 is connected by pivot 88 to an intermediate point on the link 54. The link 82 has an elongated longitudinal slot 9b which extends substantially the entire length thereof, and the link 89 carries at its forward end portion a pair of spaced

pins

92 and 94 which extend slidably through said slot 9%). The provision of the spaced

pins

92 and 94 prevents the link 80 from turning relative the link 82, but permits longitudinal sliding movement of the

links

84 and 82 relative to each other. The pin-and-slot arrangement therefore provides a telescopic action of the links 8t? and 82 whereby the distance between the

end pivots

36 and 88 may be varied. In effect, the link 86} and 82 may thus be regarded as a pair of telescopic links acting as a single link, the length of which is varied during the chair movements.

The control link 8 is mounted at one end on the support frame It) by pivot 96. The other end of said actuating link is connected by pivot 98 to an integral offset extension 99 of the connecting link 82.

FIG. 1, the body-supporting unit 24 is shown in its upright sitting position. The rear guide link 3% is in an upright position and the front guide link 32 is inclined upwardly and forwardly from its pivotal mount 42 on the carrier member 44 to its pivotal connection 4'2 with the seat. The connecting link 8% and the carrier member 44 rest upon the cross bar 18 adjacent their pivotal connection 86, thereby providing a rigid support for the front guide link 32 at the pivot 42. The connecting

links

80 and 82 are partially extended relative to one another with the

pins

92 and 94 located at an intermediate portion of the slot 9t), and the leg-rest 50 is in its retracted position beneath the forward end of seat 5t).

When the occupant of the chair in the upright sitting position of FIG. 1 wishes to assume a more comfortable position, he applies his weight rearwardly against the body-supporting unit 24. The rear guide link 30 turns about its fixed pivotal mount 34 to guide the rear portion of the body-supporting unit 24 rearwardly and downwardly. The front guide link 32 also turns about its pivotal mount 42 on the temporarily stationary carrier member 4-4 to guide the forward portion of the seat 28 upwardly and rearwardly. This first motion phase, produced by the simultaneous pivoting movement of both

guide links

30 and 32, continues until the body-supporting unit 24 reaches the intermediate, tilted sitting position of FIG. 2. At this point, the rear guide link 39 engages the cross-bar 2d, the latter halting further pivoting movement of the guide links and therefore defining the end of the first motion phase.

In the intermediate, tilted sitting position of FIG. 2, the body-supporting unit is slightly tilted but is still essentially upright and in an active position in which the users body is supported with the head and eyes forwardly-directed. This position is suitable for television, reading, sewing or the like. At the same time, the leg-rest St) has been brought to an extended, leg-supporting position in the manner which will now be described.

As the body-supporting unit 24 moves rearwardly during the first motion phase, the seat 28 carries the leg-rest control linkage 52 upwardly and rearwardly with it. The actuating link $4, pivots upwardly about its fixed pivot 96 and pushes forwardly upon the connecting link 32 through the pivotal connection 98 on the extension 99. The connecting link 82 thus slides forwardly until the pins 2 and are located at the rear end of slot 949, and the distance between

pivots

86 and 88 is increased. The over-all length of the link formed by the two telescopic connecting links 3%, 82 is therefore increased during the first motion phase. As a result, link 32 exerts a forward push against the rearwardly-moving leg-rest link 54 at point 88, causing said link 54- to turn upwardly and forwardly about its pivotal mount 58 on the seat 28. The leg-rest control linkage 52 is thus actuated to raise the leg-rest St) to the extended position of FIG. 2. In this position, the control member 44 is still seated, at the pivot 86, upon the cross-bar 1%.

It will be appreciated that because the overall length of the link formed by connecting links 89, 82 is increased during this first motion phase, a greater forward push is exerted against the link 54 than if the connecting link were of a constant length, and the leg-rest 50 is raised at a more accelerated rate during this first motion phase.

If the occupant of the chair now wishes to assume a more reclined position for greater relaxation, he applies further rearward pressure against the body-supporting unit 24. This causes the body-supporting unit 24 to turn about the pivotal connection 36 between the now stationary rear guide link 30 and the seat 23. The second motion phase is therefore a simple pivoting movement of the body-supporting unit about the pivot 36 of the rear guide link 30.

During the second motion phase, the forward portion of the seat is lifted and carries upwardly with it the front guide link 32. The latter in turn lifts the carrier member through its pivotal connection 42, causing the carrier member to pivot upwardly about its fixed pivotal mount 46. A lost motion action is therefore produced during the second motion phase, in which the lower end of the front guide link 32 moves upwardly relative to the support frame and freely follows the seat as the latter turns about the stationary pivot as.

As the forward portion of the seat turns upwardly and rearwardly during the second motion phase, it again carries with it the leg-rest control linkage 52 through the pivots 53 and 6t). Rearward movement of the connecting link 82 is again restrained by the control link 84- which pivots upwardly and continues to push forwardly through link 82 upon the leg-rest link 54. The leg-rest 5% is therefore retained extended in proper leg-supporting position forwardly of the seat 28 and substantially in a horizontal plane at the level of the front end of the seat. This second motion phase may be continued until the body-supporting unit 24 reaches the fully-tilted position of FIG. 3 in which the occupants body is disposed in a reclined position for maximum relaxation.

When the carrier member 44 pivots upwardly and forwardly on the fixed pivot 46 during the second motion phase, it carries with it the rear end of the connecting link till. Since at this time the other connecting link 82 is moving rearwardly with the seat 28 and legrest control linkage 52, with the result that the

pins

92 and 94 slide to the forward end of the slot 9%. The link formed by the link sections 3i and 82 therefore decreases in length to produce a slower upward movement of the leg-rest, thereby maintaining the leg-rest St) at a proper legsupporting position substantially level with the forward end of the seat 28 or slightly below, and substantially horizontal or parallel to the floor surface.

In the position of FIG. 3 the front guide link 32 has become axially aligned with the carrier member 44 and acts as an extension thereof providing a link of constant length between pivots 4t and 46 which will prevent further rearward pivoting of the body-supporting unit past the fully-tilted position.

It will be observed that the leg-rest actuating means comprises a four-bar linkage with the control link 34,

the carrier member 44' and the portion of the telescopic link between the pivots 86 and 93 representing the three movable links, and the portion of the support frame between the fixed pivots 46 and 9% representing the stationary link. During the first motion phase, however, the carrier member 44 remains temporarily inactive and stationary, so that pivot 86 becomes a fixed pivot. There is then provided a three-bar or triangular actuating link-age comprising the control link 84 and the telescopic link between

pivots

86 and 98 as the movable links and the portion of the support frame 1% between

pivots

86 and 96 as the fixed immovable link. Such a three-bar linkage would bind were it not for the pin-and-

slot coupling

90, 92, 94 which permits extension during the first motion phase of the telescopic link formed by the

link sections

80 and 82. During the second motion phase, the same pin-and-slot coupling 9%, 92, -94- provides a decrease in the over-all length of the connecting link formed by the telescopic sections 80*, 82 with the result that a slower elevation of the 'leg-rest is effected during the second motion phase. The linkage thus provides rapid movement of the leg-rest to the extended leg-supporting position during the first motion phase and then movement at a slower rate during the second motion phase to maintain the leg-rest in the extended leg-supporting position.

While a preferred embodiment of the invention has been shown and described herein, it is obvious that numerous additions, changes and omissions may be made in such embodiment without departing from the spirit and scope of the invention.
