Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
Rocker/reclining chairs wherein a leg rest or foot stool is moved
in concert with movements of a body-supporting unit relative to a
fixed chassis.
2. Description of the Prior Art
To my knowledge, prior to my invention, there has been no mechanism
which can be quickly and easily converted for use either with a
rocker/reclining chair or with a reclining chair. Nor has provision
been made to completely and positively limit the range and speed of
movements of the leg rest and body-supporting components of a
chair, either of the rocker/reclining type or of the reclining
type.
Too, with the prior art rocker/reclining chairs, no positive means
is provided for precluding accidental tipping of the chair while
the occupant is in a fully reclining position.
SUMMARY OF THE INVENTION
A primary object of the invention is to provide means for
precluding accidental tipping of a rocker/reclining chair while it
is in a fully reclining position.
A further object is to provide a mechanism which may be quickly,
easily and economically converted for use with a rocker/reclining
type of chair, or with a reclining type of chair.
Another object is to provide means for completely and positively
limiting the range and speed of movement of the leg rest and
body-supporting components of a chair, either of the
rocker/reclining type or of the reclining type.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
In FIGS. 1-3, I have shown the invention as incorporated in a
rocker/reclining chair; in FIGS. 4 and 5, I have shown the
invention as incorporated in a reclining chair.
With reference first to the embodiment of FIGS. 1-3, a combination
rocker/reclining chair comprises a chassis 10 fixed to a base 12
supported upwardly of the floor by legs 14, and a body-supporting
unit including a seat 16 and a backrest 18 and being rockably
supported with respect to the base and the chassis by such as
conventional rocker blocks with rocker springs disposed at each
side of the chair, or such as a rocker-spring mechanism, generally
indicated by 20, disposed centrally of the chair.
The body-supporting unit is operatively connected to rocker-spring
mechanism 20 by means of a pair of linkage mechanisms, there being
one at each side of the body-supporting unit inwardly of the
respective adjacent side of the chassis so as to be concealed from
view. Only one such linkage mechanism is herein defined, they being
identical.
A leg supporting unit or foot stool 30 may be of the one-part type
or the two-part type such as shown herein. The two-part type is
constituted by a large foot stool 32 and a small foot stool 34
pivotally interconnected. The foot stool, whichever its type, is
mounted, by means of said linkage mechanism, relative to the
forward area of seat 16, for movements between a fully retracted
position, as viewed in FIG. 1, and a fully extended position, as
viewed in FIGS. 2 and 3.
With the chair in the fully upright position, the foot stool is in
the fully retracted position. Then the large foot stool 32 is
positioned substantially flush with or in the vertical plane of the
forward end of seat 16, while the cooperant pivotally connected
small foot stool 34 extends rearwardly from adjacent the lower
extremity of the large foot stool wherefore it is concealed from
view below the seat and rearwardly of the large foot stool.
When large foot stool 32 is elevated and advanced to an extended
position, cooperant small foot stool 34 is moved therewith
accordingly and is in an axially aligned position forwardly
thereof, as viewed in FIGS. 2 and 3.
The linkage mechanisms are stationarily mounted as by bolts 35 or
the like on a cross rail 36 depending from the body-supporting unit
extending transversely relative to and between and fixed to the
upper surface of the rocker-spring mechanism 20, the lower surface
of the rocker-spring mechanism being stationarily mounted as by
bolts 37 or the like, on a bottom cross rail 39 fastened at its
opposite ends to base 12.
A generally horizontally disposed baseplate 38, extending along the
front-to-rear chair axis, is stationarily fixed by means of the
bolts 35 to the upper planar surface of cross rail 36.
A seat plate 40, similarly extending along the front-to-rear chair
axis, is stationarily secured to the adjacent side rail of seat 16
as by screws 42 or the like.
The body-supporting unit and the footstool are operatively
connected to baseplate 38 and to each other by means now to be
described.
A first L-link 44 is pivoted at 46 at its approximate midsection to
the rearward end of baseplate 38 and at its upper end at 48 to seat
plate 40 adjacent the rearward end of the latter.
A rise bar 50 is pivoted adjacent its rearward end at 52 to the
approximate midsection of baseplate 38, and is pivoted adjacent its
forward end at 54 to a second L-link 56.
Second L-link 56 is pivoted at 58 at its upper end to seat plate 40
and is pivoted at its lower end at 60 to one end of a slotted link
62 and to the rearward end of a first long link 64.
Slotted link 62 is pivoted at 66 at its opposite end to the forward
end of baseplate 38 and has a slot 68 therein adjacent its forward
end in which pivot 60 is slidable, for purposes to appear.
First long link 64 is pivoted at its approximate midsection at 70
to the approximate midsection of a first elevator link 72 and is
pivoted at its forward end at 74 to the rearward end of a second
elevator link 76.
First elevator link 72 is pivoted at its upper end at 78 to seat
plate 40 adjacent the forward end thereof and is pivoted at its
lower end at 80 to the lower rearward end of a second long link
82.
Second elevator link 76 is pivoted at its approximate midsection at
84 to the approximate midsection of second long link 82 and is
pivoted at its lower end at 86 to the lower rearward end of a small
foot stool link 88.
Second long link 82 is pivoted at its forward end at 90 to one end
of a large foot stool support plate 92 to which large foot stool 32
is fixed, and large foot stool support plate 92 is pivoted at its
opposite end at 94 to a small foot stool support plate 96 to which
small foot stool 34 is fixed.
Small foot stool link 82 is pivoted at its forward end at 98 to
small foot stool support plate 96 and is pivoted at 100 rearwardly
of its forward end to the lower end of a connecting link 102
pivoted at its opposite end at 104 to large foot stool support
plate 92.
A tension spring 106 is fixed at one end to slotted link 62 and is
fixed at its opposite end to first long link 64, the spring acting
much in the manner of a buffing device to control the speed with
which the foot stool is extended and to buffer the tilting of the
chair as it approaches the fully reclined position and additionally
to insure that the foot stool remains retracted when the chair is
in the upright position and the occupant is rocking.
The functions of slotted link 62 are three fold: 1) it precludes
extension of the foot stool beyond a desired limit as dictated by
pivot pin 60 reaching the forward extremity of slot 68; 22) it
precludes reclining of the chair without a concomitant extension of
the foot stool; and 33) it precludes retraction of the foot stool
while the chair is in a fully reclined position.
Any rocking movement of the body-supporting unit, while the chair
is in any reclining position, is precluded when a roller 108
provided on the free end of first L-link 44 contacts the upper
surface of a bearing block 110 fixed to base 12.
When the chair is in the upright position of FIG. 1, roller 108 is
disposed upwardly of the bearing block wherefore the
body-supporting unit may be rocked.
When the chair is moved to either of the reclining positions of
FIGS. 2 or 3, the roller swings downwardly into contact with the
bearing block to preclude rocking.
The upper end of a stop link 112 is fixed as by rivets 114 or the
like to the rear end of seat plate 40 and extends downwardly
therefrom.
When the chair is in the fully reclining position of FIG. 3, the
lower end of stop link 112 contacts the upper surface of bearing
block 110, thereby effectively precluding any accidental tipping of
the chair from such fully reclining position.
A stop pin 116 on seat plate 40, when contacted by a leading edge
of second L-link 56, limits the range of outward movement of the
foot stool, while the lower surface of rise bar 50, when it
contacts baseplate 38, limits the range of downward movement of the
body-supporting unit.
In use, when the chair is moved from an upright, FIG. 1, position
to an intermediate reclining, FIG. 2, position, rise bar 50 remains
in a generally horizontal position in contact with baseplate 38,
roller 108 swings downwardly into contact with bearing block 110
and the large and small foot stools are extended, the speed of such
extension being controlled by spring 106, while second L-link 56
contacts stop pin 116 to preclude further foot stool extension.
When the chair is moved from an intermediate reclined, FIG. 2,
position, to a fully reclined, FIG. 3, position, rise bar 50 pivots
relatively to baseplate 38, pivot pin 60 moves to the forward
extremity of slot 68 in slotted link 62 to preclude closing of the
foot stool while in the fully reclined position, and stop link 112
contacts bearing block 110 to preclude accidental tipping of the
chair. During this movement from intermediate to fully reclined
position, roller 108 remains in contact with the bearing block,
merely rolling therealong.
The mechanism just described may be quickly and easily modified for
use with a reclining chair without the rocking feature by the
simple expedient of repositioning pivot 52, removing stop link 112,
and removing the lower roller-bearing end of first L-link 44.
Such a modified linkage is shown in FIGS. 4 and 5, which illustrate
a reclining chair without the rocking feature.
Herein, the mechanisms are fixed to a cross rail 136 which extends
between, and is fastened at its opposite ends to, the arms of the
chair chassis. The pivot 52 has been moved upwardly, the stop link
112 has been removed, and first L-link 44 has been replaced by a
straight link 144 wherefore the roller 108 is also omitted.
