Definitions

  • T-cushion recliners of the prior art all teach the use of a handle or lever usually on the side of the chair for actuating the legrest or footrest after the seat and backrest are reclined and this for the reason that no one has been able to overcome the problem of the T-cushion binding at the arms of the chair.
  • a primary object of the invention is to provide, in a reclining chair, a T-cushion seat and mechanism for automatically moving the seat between sitting and reclining positions coincident with the tilting movement of a backrest and the extension of a foot stool without the use of an external handle or lever which detracts from the appearance of the chair.
  • FIG. l is a front elevational view of a T-cushion chair of the type embodying the invention.
  • FIIG. 2 is a fragmentary, side elevational View of a T- cushion chair in the upright or sitting, foot stool retracted position and with portions of the chair removed and other portions shown in phantom for purposes of clarity;
  • FIG. 3 is a fragmentary, side elevational view of the chair and mechanism of FIG. 2 in the partially-reclined, foot stool extended position;
  • FIG. 4 is fragmentary, side elevational view of the chair and mechanism of FIG. 3 in the fully-reclined, foot stool extended position;
  • FIG. 5 is a fragmetnary top line 5-5 of FIG. 4.
  • the chair is of the T-cushion type, being so designated because the seat cushion is in the shape of an inverted T with portions thereof disposed forwardly of the arms of the chair.
  • the chair incorporates a T-cushion seat 10, a back Y rest 12, chair side arms 14, a chassis 116, a foot stool 18 disposed flush with the forward edge of the seat in the chair upright position, and chair legs 20 for supporting the chassis upwardly of the floor F.
  • a linkage mechanism constitutes one of a pair, there lbeing one such linkage mechanism at each side of the seat inwardly of the respective adjacent side of the chassis so as to be concealed from view.
  • seat side rails 22 which extend in a front-to-rear chair direction and are interconnected at their ends by -front and rear stretchers 24 and 26 respectively, same constituting a supporting framework for the seat.
  • Rear stretcher 26 is fixed to the side rails by a bolt 28 which extends through an upper flange 30 of the side rail and through the stretcher with a nut 3-2 threaded thereon.
  • Front stretcher 24 is xed to the side rails by a bolt 34 which extends downwardly through upper ange 30 of the side rail and through the stretcher with a nut 36 threaded thereon.
  • the front stretcher extends outwardly from the side rail to form a support for the T-portion of the cushion. Accordingly, additional securing means is provided and constitutes a bolt 38 which extends inwardly through the stretcher and through a flange 40 provided adjacent the forward end of the side rail and has a nut 42 threaded thereon.
  • Back rest 12 is constituted by a pair of parallel side rails 44 connected by a plurality of cross rails, not shown, in conventional manner.
  • the chassis comprises spaced parallel and upright sides 46 interconnected by front and rear stretchers 48 and 50 respectively.
  • a back rest link 56 has its upper end xed to the backrest side rails 44 by bolts or screws 58 and has its lower end pivotally connected to mounting plate 52 as at 60 whereby the backrest is pivotally related to the chassis.
  • a push bar 62 serves as a means for connecting the backrest to the seat, the seat to the chassis and the footstool to the chassis and seat.
  • a pair of back links connect back rest link 56 to push bar ⁇ 62 and comprises a first back link 64 pivoted at its upper end at 66 to back rest link 56 and at its lower end at 68 to the upper end of a second 4back link 70, said second back link being pivoted adjacent its upper end at 71 to mounting plate 52 (see FIG. 4) and at 72 at its lower end to the rear end of push bar 62.
  • a pair of links additionally connects the back rest to the seat and to the push bar and comprises a slotted control link 74 pivoted at its rear end at 76 to second back link 70 adjacent the lower end thereof and having a slot 78 at its forward end in which a pin 80 carried by seat side rail 22 is receivable, said pin additionally serving to pivotally connect the upper end of a support link I82 to the seat, the lower end of said support link being pivoted to the push bar at 84.
  • the control link serves the dual functions of precluding reclining movement of the seat and back rest unless the foot stool is extended and precluding any retraction of the foot stool while the chair is in fully reclined position, with the supporting link supporting the rear end of the seat.
  • a system of links generally indicated by 85 further interconnects the seat, chassis and push bar to insure smooth, coordinated movements of the various chair components.
  • this system of links performs the allimportant function of guiding the seat during reclining movement of the chair components so that as the chair components are reclined the seat moves not only upwardly but forwardly to preclude binding with the chair arms.
  • This system of links includes a seat link 86 pivoted at its rear end at 88 to the seat side rail and pivoted at its opposite end at 90 to the upper ends of a first connecting link 92 and a first power link 94.
  • First connecting link 92 is pivoted at its lower end at 96 to the rear end of a cross link 98.
  • First power link 94 is pivoted at its lower end at 100 to an L-link 102 pivoted at its upper end at 104 to mounting plate 52.
  • Cross link 98 is pivoted at its approximate midsection at 106 to L-link 102 and at its forward end at 108 to the forward end of a second connecting link 110 which is pivoted at its opposite end at 112 to mounting plate 52.
  • L-link 102 is pivoted at its forward end at 114 to the lower end of a second power link 116 pivoted at its upper end at 118 to push bar 62.
  • a system of links generally indicated by 119 further interconnects the foot stool to the seat and to the chassis to insure smooth coordinated movements of the foot stool as the chair components are moved ⁇ between upright and reclining positions.
  • This system of links includes a first propeller link 120 pivoted at its upper end at 122 to seat side rail 22 and pivoted adjacent its upper end at 124 to the forward end of push bar 62.
  • First propeller link 120 is pivoted at its lower end at 126 to the lower end of a push link 128 pivoted at its approximate midsection at 130 to a second propeller link 132 and pivoted at its forward end at 134 to the upper end of a third propeller link 136.
  • Second propeller link 132 is pivoted at its upper end at 138 to seat side rail 22 and is pivoted at its lower end at 140 to the lower end of a first foot stool link 142 which is pivoted at its upper end at 144 to a foot stool plate 146.
  • Third propeller link 136 is pivoted at its approximate midsection at 148 to the approximate midsection of first foot stool link 142 and is pivoted at its lower end at 150 to the lower end of a second foot stool link 152 which is pivoted at its upper end at 154 to foot stool plate 146.
  • the foot stool cross stretcher 156 is fixed to the foot stool plate by screws 158 or the like.
  • a tension spring 160 extends between third propeller link 136 and rst foot stool link 142 being fixed at one end to the pivotal connecting pin 134 and at its opposite end to a pin 162 provided on first foot stool link 14-2.
  • Spring 160 helps to control the movement of the foot stool as it is extended and aids in its retraction when the chair is returned from reclining positions to upright position.
  • the usual fabric backing 164 is suspended from the back rest to conceal the various structural features of the chair.
  • Such forward movement of push bar 62 sets up a concomittant forward movement of seat rail 22 and seat 10 and the extension of the foot stool, it being recalled that the seat rail is connected to the push bar by support link 82 and first propeller link 120.
  • Swinging movement of first propeller link 120 causes all of the links of the system of links 119 to swing outwardly, thereby moving the foot stool from its stored generally vertical position flush with the front of the chair to an extended generally horizontal position forwardly of the chair.
  • the chair occupant need only sit up to return the chair from FIG. 4 to FIG. 3 position, and by exerting pressure of the heels on the foot stool, he may return the chair from the FIG. 3 to the FIG. 2 position.
  • a stop 174 on second propeller link 132 engages in a notch 176 on the rear edge of third propeller link 136 to preclude further retraction of the foot stool.
