Pmmmm i m sum as 0F 11 mmv PATENTEBSH'! 1 I975 SHEET 11 0F 11 RECLINING CHAIR The invention provides a reclining chair which can be positioned in close proximity to a wall or lamp or other article of furniture.

It has long been a problem in the reclining chair art that the chair of necessity had to be placed a sufficient distance away from the wall or article of furniture as to allow movement of part of the body-supporting unit in the area rearwardly of the vertical plane of the rear legs of the chair, the unit, and more particularly the back thereof, moving rearwardly in the course of any shifting between upright and any reclined positions.

'The problem is here solved by the provision of means for moving the body-supporting unit forwardly relative to the platform and away from the wall as reclination ensues wherefore the chair can be positioned in close proximity to a wall.

In the drawings:

FIGS. 1 3 are schematic representations of a chair embodying one form of the invention showing the positions of the several chair components relative to a wall as the chair is moved from an upright sitting position first to a partially-reclined position and then to a fullyreclined position;

FIG. 4 is a fragmentary view, in longitudinal section, of the chair of FIGS. 1 3 in upright, sitting position;

FIG. 5 is a view, similar to FIG. 4, showing the chair in intermediate reclined or TV position;

FIG. 6 is a view, similar to FIG. 4, showing the chair in fully-reclined position;

FIG.'15 is aview, similar to FIG. 14, showing the chair in intermediate reclined or TV position;

FIG. 16 is a view, similar to FIG. 14, showing the chair in fully-reclined position;

FIG. 17 is a fragmentary view, in longitudinal section, of a portion of the chair of FIG. 14, with parts omitted for simplicity;

FIG. 18 is an enlarged, fragmentary view, in end elevation, of the portion of the chair of FIG. 17; and

FIG. 19 is an enlarged, fragmentary view, in top plan, of the portion of the chair of FIG. 17.

Referring first to FIGS. 1 3, chairs of the type envisioned having a platform B and a chassis C mounting a body-supporting unit D (i.e., seat and back which may be unitary a to each other or shiftable with respect to each other) and a leg supporting unit L, are shiftable between an upright sitting position where little, if any, of the body supporting unit is disposed in an area rearwardly of the vertical plane of the rearwardly disposed legs or of the rearwardmost portion of the platform, and various positions of reclination where some portion of the body supporting unit is disposed in that area.

This being so, chairs heretofore known have had to be positioned distantly of a room wall W if reclination was to be accomplished successfully and without physical contact being had between chair and wall.

If positioning close to a wall was desired, the chair would have to be withdrawn away therefrom in order to allow successful reclination.

With the chair hereof, as body-zsupporting unit D is reclined, chassis C moves linearly relative to platform B away from wall W to provide the necessary clearance for the body-supporting unit as the chair elements move between the upright position of FIG. I and the partially reclined position of FIG. 2 and/or the fullyreclined position of FIG. 3. V

In the form of the invention seen in FIGS. 4 7, platform B comprises pairs of front and rear legs 10 and 12 respectively disposed at each side of the chair and interconnected by side rails 14 extending in a front-torear chair direction and by transversely-extending cross-rails l6 interconnecting the side rails in known manner.

A vertically-oriented slotted plate 18 is fixed to each side rail 14 as by screws or bolts 20, extends upwardly therefrom, and is provided with a pair of spaced, generally horizontally-extending, aligned, front and rear slots 22 and 24 respectively. The forwardly-facing extremity of each slot serves as a small rise, indicated by 23 and 25 respectively, for purposes to appear.

Chassis C includes a pair of spaced, upright side walls 26 of any conventional configuration and disposed at each side of the chair, each side wall carrying a chair arm 28.

Body-supporting unit D includes a seat 30 and a back 32, which may be unitary, as shown in FIGS. 1 7, or which may be separable, as will be described with reference to FIGS. 14 19.

The means interconnecting platform B, chassis C, body-supporting unit D and leg-supporting unit L includes a pair oflinkage mechanisms, there being one at each side of the body-supporting unit inwardly of the respective adjacent side wall of thlfi chassis so as to be. concealed from view. Only one such linkage mechanism is herein defined, they being identical for all practical purposes, one being a right hand and one being a left hand mechanism. Such mechanism could be of the types disclosed in US. Pat. No. 3,044,827 of July 17, 1962, No. 3,058,774 of Oct. 16, 1962, or No. 3,166,352 of Jan. 19, I965, to name but a few, or their kinematic equivalents, for purposes of exemplification.

A generally horizontally-disposed base plate 34, extending along the front-to-rear chair axis, is stationarily fixed as by bolts 36 and nuts 38 to a cross rail or stretcher 40 which extends transversely relative to and between chassis side walls 26, and is fixed at its opposite ends to a plate 42 mounted on each side wall as by screws or bolts 44.

Leg supporting unit L may be of the one-part type or of the two-part type, as shown herein. The two-part type is constituted by a large foot stool 46 and a small foot stool 48 pivotally interconnected. The leg supporting unit, whichever its type, is mounted, by means of said linkage mechanisms, relative to the forward area of seat 30, for constrained movements between a fullyretracted position, as viewed in FIGS. 1, 4 and 7, and a fully-extended position, as viewed in FIGS. 3, and 6.

With the chair in fully upright position, the leg sup porting unit is in fully-retracted position with large footstool 46 positioned substantially flush with or in the vertical plane of the forward end of seat 30. and with the cooperant pivotally connected small footstool 48 extending rearwardly from adjacent the lower extremity of the large footstool so as to be concealed from view below the seat and rearwardly of the large footstool. When large footstool 46 is elevated and advanced to an extended position, cooperant small footstool 48 is moved therewith accordingly and is placed in an axially-aligned position forwardly thereof.

The body-supporting unit and the leg supporting unit are operatively connected to base plate 34 and to each other.

A seat plate 50 extends along the front-to-rear chair axis and is stationarily secured to the adjacent side rail of seat 30 as by screws or bolts 52.

A pivot link 56 is pivoted at 56 at its lower end to the rearward end of the base plate 34 and at its upper end at 58 to seat plate 50 adjacent the rearward end of the latter.

A rise bar 60 is pivoted adjacent its rearward end at 62 to the approximate midsection of base plate 34, and is pivoted adjacent its forward end at 64, (see FIG. 6), to an L-link 66.

L-link 66 is pivoted at 68 at its upper end to seat plate 50 and is pivoted at its lower end at 70 to one end of a slotted link 72 and to the rearward end ofa first long link 74.

Slotted link 72 is pivoted at 76 at its opposite end to the forward end of base plate 34 and has a slot 78 therein adjacent its forward end in which pivot 70 is slidable.

First long link 74 is pivoted at its approximate midsection at 80 to the approximate midsection of a first elevator link 82 and is pivoted at its forward end at 84 to the rearward end of a second elevator link 86.

First elevator link 82 is pivoted at its upper end at 88 to seat plate 50 adjacent the forward end thereof and is pivoted at its lower end at 90 to the lower rearward end of a second long link 92.

Second elevator link 86 is pivoted at its approximate midsection at 94 to the approximate midsection of secnd long link 92 and is pivoted at its lower end at 96 to the lower rearward end ofa small foot stool link 98.

Second long link 92 is pivoted at its forward end at 100 to one end of a large foot stool support plate 102 to which large foot stool 46 is fixed; large footstool support plate 102 is pivoted at its opposite end at 104 to a small footstool support plate 106 to which small footstool 48 is fixed.

Small footstool link 98 is pivoted at its forward end at 108 to small footstool support plate 106 and is pivoted at 110 rearwardly of its forward end to the lower end ofa connecting link 112 which is pivoted at its opposite end at 114 to large footstool support plate 102.

A buffer-retainer tension spring 116 is mounted at one end on slotted link 72 and is mounted at its opposite end on first long link 74, the spring acting much in the manner of a buffing device to buffer chair tilting as it approaches fully-reclined position and additionally to insure that the leg-supporting unit remains retracted when the chair is in upright position.

The functions of slotted link 72 are three-fold: 1) it serves as a carrier for the buffer-retainer spring 116; 2) it precludes reclining of the chair without a concomitant extension of the leg-supporting unit; and 3) it precludes retraction of the leg-supporting unit while the chair is in fully-reclined position.

A stop pin 118 on seat plate 50, when contacted by a leading edge of L-link 66, limits the range of outward movement of the leg-supporting unit.

A first stop surface 120 of rise bar 60, when it contacts base plate 34, limits the range of downward movement of the body-supporting unit.

In the chair upright position, second long link 92 abuts first long link 74 to limit the range of rearward movement of the leg-supporting unit, with a flat 93 on the rearwardly-facing face of link 92 being receivable in a notch on the forwardly-facing face of link 74.

In use, when the chair is moved from upright position to an intermediate reclining position, rise bar 60 re mains in a generally horizontal position, with first stop surface thereof in contact with base plate 34, and with the large and small foot stools extended, the ease of such extension being controlled by spring 116, while L-link 66 contacts stop pin 118 to preclude further legsupporting unit extension.

When the chair is moved from intermediate reclined position, to a fully reclined position, rise bar 60 pivots at 62 relatively to base plate 34, pivot pin 70 moves forwardly in slot 78 of slotted link 72 to preclude closing of the leg-supporting unit while in the fully reclined position, and a second stop surface 122 of rise bar 60 contacts base plate 34 to limit the range of reclining movement of the body-supporting unit.

Chassis C is slidably related to base B by means of front and rear rollers and 132 respectively which extend outwardly from plate 42 at each side wall 26 of the chassis, front roller 130 being rideable in front slot 22 of plate 18 and rear roller 132 being rideable in rear slot 24 therein.

The rises 23 and 25, together with spring 116 control or lessen any falling sensation as reclining takes place, it being understood that the greater the upward slope of each rise, the more difficult forward movement of the chassis becomes.

In the chairupright position of FIG. 4, the rollers are disposed at the rear ends of their respective slots 22 and 24.

As the body-supporting unit is moved to the intermediate reclining position of FIG. 5, the rollers slide along the slots to a position wherein they are disposed somewhat forwardly of the approximate midsections of the slots.

Movement of the body-supporting unit to fullyreclined position moves the rollers to the forward extremities of the slots as shown in FIG. 6, with the rises 23 and 25 and spring 116 controlling such movement as aforesaid.

A propeller link 134, pivoted at its upper end at 136 to backrest 32 and at its lower end at 138 to plate 18, propels and controls the range of movement of the body-supporting unit relative to the platform.

The key to the invention is in propeller link 134 for it propels the body-supporting unit and chassis forwardly as reclination occurs, as well as rearwardly on assuming the upright position, with the rollers 130 and 132 riding in the slots 22 and 24 respectively.

In the chair upright position roller 132 rests in a slight recess or groove 24 provided adjacent the rearward end of slot 24, the groove serving as an impediment to unwanted sudden sliding movement of the roller relative to the slot.

In effect, in movement from upright to intermediate position, the rear roller must be lifted out of groove 24' with the chassis rotating about front roller 130 as reclination occurs.

The single propeller link 134 of FIGS. 1 7 is replaced in the modified form of FIGS. 8 10 by trio of links.

The leg-supporting unit and reclining linkage have been omitted in FIGS. 8 10 for purposes of simplicity.

Herein, a primary propeller link 234 is pivoted at its upper end at 236 to one end of a secondary propeller link 240 and at its lower end at 238 to plate 18, with secondary propeller link 240 being pivoted at its opposite end at 242 to the rearward end of base plate 34.

A control link 244 is pivoted at one end at 246 to backrest 32 and at its opposite end at 248 to the approximate midsection of primary propeller link 234.

The trio of links operates directly on the chassis through the connection 242 with base plate 34, while operating on the body-supporting unit through control link 244, wherefore linear movements of the chassis and body-supporting units relative to the platform are effected.

In the embodiment of FIGS. 11 13, the legsupporting unit and reclining linkage have once again been omitted for simplicity.

In this form of the invention, the propelling means comprises a roller 334 fixed to backrest 32 and rideable in a cam slot 336 provided in an extension 338 of plate 18.

As reclination occurs, the captured roller drives the chassis and body-supporting unit forwardly. On assuming the upright position the chassis and bodysupporting unit is driven rearwardly.

The somewhat dog-leg shape of slot 336 provides a dwell for the intermediatereclining or TV position as shown in FIG. 12.

The embodiment of FIGS. 14 19 has been modified for use with a chair of the type having a separable seat and back.

In this instance a double-track system is employed, such a system being necessary since, with chairs of this type, the components travel farther away from the wall. Thus, a double track was designed so that all of the sliding means would be under cover of the chair.

Basically, however, the sliding and motivating means are the same as those shown for use with the unitary seat and back chair of FIGS. 1 l3.

Herein, a platform B supports a chassis C' mounting a body-supporting unit D and a leg-supporting unit L'.

The means interconnecting platform B, chassis C, body-supporting unit D' and leg-supporting unit L includes a pair of linkage mechanisms, there being one at eachside of the body-supporting unit inwardly of the respective adjacentside wall of the chassis so as to be concealed from view. Onlyone such linkage mechanism is herein defined, they being identical for all practical purposes, one being a right hand and one being a left hand mechanism.

The mechanism shown is identical to that shown and described in my U.S. Pat. No. 3,137,521 of June 16,

' 1964. However, it could be of any of the types as disclosed in U.S. Pat. No. 3,069,201 of Dec. 18, 1962, or No. 3,166,353 of .Ian. 19, 1965 or No. 3,359,034 of Dec. 19, 1967, to name but a few, or their kinematic equivalents, for purposes of exemplification.

Since the mechanism is described in detail in the aforementioned U.S. Pat. No. 3,137,521, such detailed description will not be repeated here.

As body-supporting unit D is reclined, chassis C moves linearly relative to platform B away from a wall, not shown, to provide the necessary clearance for the body-supporting unit relative to the wall as the chair elements move between the upright position of FIG. 14 and the partially reclined position of FIG. 15 and/or the fully-reclined position of FIG. 16.

In the form of the invention seen in FIGS. 14 19, platform 8' comprises pairs of front and rear legs 410 and 412 respectively disposed at each side of the chair and interconnected by side rails 414 extending in a front-to-rear chair direction and by transverselyextending cross-bars 416 interconnecting the side rails in known manner.

Chassis C' includes a pair of spaced, upright side walls 426 of any conventional configuration and disposed at each side of the chair, each side wall additionally constituting a chair arm.

Body-supporting unit D includes a seat 430 and a back 432, which are separable, as shown.

As part of the reclining mehcanism, a generally horizontally-disposed base plate 434, extending along the front-to-rear chair axis, is stationarily fixed as by a bolt 436 to one of a pair of cross bars 440 extending transversely relative to and between chassis side walls 426, the cross bars being fixed at their opposite ends to a plate 442 mounted on each side wall. Screws or bolts 444 attach base plate 434 to plate: 442.

Leg supporting unit L may be of the one-part type or of the two-part type, as shown herein. The two-part type is constituted by a large foot stool 446 and a small foot stool 448 pivotally interconnected. The leg supporting unit, whichever its type, is mounted, by means of said linkage mechanisms, relative to the forward area of seat 430, for constrained movements between a fully-retracted position, as viewed in FIG. 14 and a fully-extended position, as viewed in FIGS. 15 and 16.

A rise bar 460 pivoted at 462 to base plate 434 serves as the primary means of interconnection between the leg-supporting unit, body-supporting unit and chassis.

A backlink 464 is fixed at one end as by screws 466 to back 432 and is pivoted at its opposite end at 468 to seat 430, to interconnect the seat and back.

A pivot link 470 pivot4d at one end at 472 to link 464 is pivoted at its lower end at 474 to base plate 434 to further interconnect the body-supporting unit and chassis.

A first vertically-oriented slotted plate 420 is fixed to each side rail 414, extends upwardly therefrom, and is provided with a pair of spaced, generally horizontallyextending, aligned, front and rear slots 422 and 424 respectively.

A second vertically-oriented slotted plate 480 is disposed inwardly of and in spaced parallelism to first slotted plate 420 and is provided with a pair ofspaced, gen erally horizontallyextending, aligned front and rear slots 482 and 484 respectively,.which slots are disposed above the plane of slots 422 and 424 of first plate 420.

A first set of front and rear rollers 425 and 427 respectively is provided, with front roller 425 being rideable in front slot 422, and with rear roller 427 being rideable in rear slot 424.

The front rollers 425 at each side of the chair are interconnected by a cross rod 425 and the rear rollers 427 are interconnected by a cross rod 427, the cross rods extending through the adjacent second slotted plates 480.

A second set of front and rear rollers 486 and 488 respectively extends outwardly from plate 442 with front roller 486 being rideable in front slot 482, and with rear roller 488 being rideable in rear slot 484.

As the body-supporting unit is reclined, the chassis slides relative to the base in two stages: to the position shown in FIG. 15, wherein the second set of rollers 486 and 488 slides to the forward ends of slots 482 and 484 of second plate 480; and to the position shown in FIG. 16, wherein the first set of rollers 425 and 427 slides to the forward ends of slots 422 and 424 of first plate 420.

In the first stage of movement, from upright to inter mediate position the chassis and both plates 420 and 480 remain stationary, with plate 442 moving to carry the body-supporting unit forwardly as the rollers 486 and 488 ride in their respective slots 482 and 484.

In the second stage of movement from intermediate to fully-reclined position, the chassis and plate 480 are moved forward relative to the stationary plate 420, with the rollers 425 and 427 riding in their respective slots 422 and 424.

Of course, these operations are reversed when the body-supporting unit is returned from fully-reclined position to upright position.

A propeller link 490, pivoted at its upper end at 492 to link 464 and at its lower end at one of the cross bars 416 to the platform propels and controls the range of movement of the body-supporting unit relative to the platform.

The propeller link 490 propels the body-supporting unit and chassis forwardly as reclination occurs, as well as rearwardly on assuming the upright position, with the two sets of rollers riding in the two sets of slots.

Of course, the modified propeller means of FIGS. 8 13 could be employed in lieu of the single propeller link 490.

Plate 442 is unconstrained. Thus, it is possible that the chassis could move relative to slots 422 and 424 before plate 442 moves relative to slots 482 and 484.

However, this contingency can be avoided by the simple expedients of extending a spring, not shown, between plates 420 and 480, or by placing a slight groove or depression, also not shown, at the rearward extremity of groove 424, whereby a slight restraint is placed on roller 427.

While rollers rideable in slots have been described and shown, it will be understood that any appropriate slide means may interconnect the several chair components.
