  • Means for controlling the movement of the leg rest and comprises a primary control link 80 pivoted at 82 adjacent one of its ends to primary actuator link 30 and pivoted at 84 at its opposite end to the rearward end of a secondary control link 86, which is pivoted at 88 at its approximate midsection to the approximate midsection of secondary actuator link 32 and is pivoted at its forward end at the pivot 44 to the rearward end of primary propeller link 46.
  • Primary control link 80 is spring-loaded by a tension spring 90 fixed at one end to a pin 92 provided on the inner free end of control link 80 and fixed to its opposite end to a pin 94 provided on seat bracket 28.
  • the control means regulates the speed and manner of movement of the leg rest, while the spring loading of control link 80 ensures that the leg rest remains closed while the chair is upright and the occupant is rocking.
  • Means for ensuring coordinated reclining movement of the seat and back rest components of the body-supporting unit coincident with extension of the leg rest includes a rise bar 96 pivoted at its forward end to primary actuator link 30 at the pivot 82 and pivoted at 97 at its opposite rearward end to a plate-like coordinating link 98 which is pivoted at 100 to mounting bracket 26.
  • the coordinating link is the focal point or hub for the operative connection between the chassis, seat, back rest and leg rest.
  • the coordinating link is operatively connected to the leg rest through pivotal connection 97 with rise bar 96 and is operatively connected to chassis 14 through pivotal connection 100.
  • Back rest link 108 is fixed as by screws 110 to a side rail 112 of the back rest and is pivoted at 114 at its forward end to mounting bracket 26.
  • Coordinating link 98 is operatively connected to the seat by a system of links including a slotted link 116 pivoted at 118 at its lower end to the coordinating link and having a central slot 128 therein in which a pin 122 provided on seat bracket 28 is slideable.
  • a connecting link 124 is pivoted at its upper end to pin 122 and at 126 at its lower end to rise bar 96, thereby effecting an operative connection between the seat and leg rest.
  • a system of links is provided for raising seat bracket 28 and moving it and seat 10 forwardly to clear the chair arms as the body-supporting unit is reclined while counter-balancing the chair back to preclude any objectionable falling sensation on the part of the chair occupant.
  • Said system of links includes a seat link 128 pivoted at 130 at its rearward end to seat bracket 28 and pivoted at 132 at its opposite end to the upper end of a pivot link 134.
  • Pivot link 134 is pivoted at 136 at its approximate midsection to the approximate midsection of a leg rest link 138 and is pivoted at 148 at its lower end to the upper end of a chassis link 142 which is pivoted at 144 at its lower end to mounting bracket 26.
  • Leg rest 138 is pivoted at its rearward end at 146 to mounting bracket 26 and is pivoted at 148 at its forward end to the lower end of a rise bar link 150 which is pivoted at 152 at its upper end to rise bar 96.
  • Additional stop means comprises, a stop surface 154 on coordinating link 98 engageable with the lower surface of back rest link 108 to limit the degree of angularization of the back rest when the chair is in the fully reclined position, as shown in FIG. 5.
  • Means for precluding rocking movement of the bodysupporting unit, when the leg rest is extended comprises a pair of arresting means, one disposed adjacent the chair front, and the other adjacent the chair rear, each of which is engageable with rocker base 22.
  • the forward arresting means is generally indicated by 168 and comprises a forward roller link 162 pivoted at 164 at its upper end to mounting bracket 26 and having a roller 166 rotatably mounted on its lower end and engageable with a wear plate 108 provided on the upper surface of rocker base 22.
  • roller can alternatively make direct contact with the base.
  • leg rest link 138 rests upon an offset flange 200 provided on mounting bracket 26, this flange acting as a stop to preclude any drooping of the linkage mechanism.
  • a forward actuating link 170 is pivoted at 172 at its forward end to forward roller link 162 and is pivoted at 174 at its opposite end to coordinating link 98.
  • the rear arresting means is generally indicated by and comprises a rear roller link 182 pivoted at 184 at its upper end to mounting bracket 26 and having a roller 186 rotatably mounted on its lower end and engageable with a bearing plate 188 provided on the upper surface of rocker base 22, or directly engageable with the upper surface of the base.
  • a rear actuating link 90 is pivoted at 192 at its lower end to rear roller link 182 and is pivoted at 194 at its opposite end to coordinating link 98.
  • each of the arresting means When the chair is in upright position, each of the arresting means is in a raised position out of contact with the rocker base, whereby the chassis may be rocked at will.
  • the arresting means move into contact with the rocker base to preclude rocking.
  • each of the arresting means is operatively connected to coordinating link 98, each swings as the coordinating link rotates when the body-supporting unit is reclined, moving into engagement with the rocker base to provide positive and dual arresting means to preclude rocking, when the chair is in an intermediate or fully reclined position.
  • Slotted link 116 precludes reclining of the body-supporting unit without concomitant leg rest extension and precludes leg rest retraction while in the fully-reclined position.
  • T cushion because the seat does not move rearwardly, as is common in reclining chairs when the back is tilted, but rather moves forwardly and its rear end moves slightly downwardly, and it is the weight of the occupant which propels the leg rest forwardly and upwardly. Since the seat moves forwardly, it cannot bind on the arms of the chair to hamper or preclude reclining movements or extension of the leg rest.
  • A. rocker reclining chair comprising: a stationary rocker base, a chassis rockably mounted on said base, a body-supporting unit including a back rest and a T-cushion seat pivotal relative to said chassis and pivotal each relative to the other, means mounting said body-supporting unit for movements relative to said chassis successive- 1y between an upright sitting position and an intermediate reclined position and a fully reclined position, a leg rest movable between retracted position wherein it is disposed forwardly of the seat, actuating means connecting the body-supporting unit and chassis and leg rest for automatically moving said leg rest responsively to movement of the body-supporting unit, said actuating means moving the T-cushion seat forwardly and upwardly as the body-supporting unit is reclined and the leg rest extended whereby binding between the T-cushion and the chassis is precluded, and dual arresting means operatively connected to said actuating means and movable into engagement with the rocker base when the bodysupporting unit is reclined for precluding rocking
  • said dual arresting means comprise forward and rear roller links each rotatably engageable with the rocker base.
