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 leg rest either before or after the seat and back rest 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 back rest and the extension of a leg rest without the use of an external handle or lever which detracts from the appearance of the chair.
  • FIG. 1 is a front elevational view of a T-cushion reclining chair of the type embodying the invention
  • FIG. 2 is a fragmentary, top plan view of one of a pair of linkage mechanisms of the chair
  • FIG. 3 is a fragmentary, side elevational view of an embodiment of a T-cushion reclining chair, with the chair being shown in the upright, sitting position, with the leg rest retracted, and with portions of the chair removed for purposes of clarity;
  • FIG. 4 is a fragmentary, side elevational view of the chair and mechanism in the intermediate position, with the leg rest extended;
  • FIG. 5 is a fragmentary, side elevational view of the chair and mechanism in the fully-reclined position, with the leg rest extended.
  • the chair constituting the disclosed embodiment of the invention is of the T-cushion type, being so designated because the seat cushion is in the shape of an inverted T, as seen in FIG. 1, with portions thereof disposed forwardly of the arms of the chair.
  • the chair incorporates a T-cushion seat 10, a back rest 12, a chassis 14 inclusive of chair side arms 16, a two-part, foldaway leg rest generally indicated by 18 and having one of its parts 20 disposed flush with the forward edge of the seat in the chair upright position, and legs 22 for supporting the chassis upwardly of the floor.
  • a onepart leg rest may be employed with equal facility.
  • Seat 10 and back rest 12 are pivotally secured relative to each other and cooperantly constitute a bodysupporting sub-assembly having a pivotal relationship to chassis 14.
  • a linkage mechanism constitutes one of a pair, there being one such linkage mechanism at each side of the body-supporting sub-assembly inwardly of the respective adjacent side of the chassis so as to be concealed from view.
  • a vertically-disposed mounting bracket 26 extends along the front-to-rear dimension of the chair and is stationarily secured to the coplanar-disposed adjacent side Wall of chassis 14.
  • a seat bracket 28 also extending in a front-to-rear direction of the chair, is stationarily secured to transversely-extending front and rear stretchers 29 and 31 respectively of seat 10.
  • Leg rest 18 is mounted, by means of the linkage mechanism, relative to the forward end of seat 10 for movement between fully-retracted position, as seen in FIGS. 1-3, and fully-extended positions as seen in FIGS. 4 and 5.
  • major leg rest part 20 In the fully-retracted position, which is the fully-upright or sitting position, major leg rest part 20 is posi tioned substantially flush with the forwardly facing front edge of the seat, while a cooperant minor leg rest part 21 is positioned so as to extend rearwardly from the lower end of the major part and to be concealed from view beneath the seat.
  • Leg rest 18 is suspended relative to seat by a pair of actuator links, namely: a primary actuator link and a secondary actuator link 32.
  • Primary actuator link 30 is pivoted at its upper end at 34 to seat bracket 28 and at its lower end at 35 to the lower end of a primary drive link 35.
  • Secondary actuator link 32 is pivoted at its upper end at 38 to seat bracket 28 and at its lower end at 40 to the lower end of a secondary drive link 42.
  • Primary drive link 36 is pivoted at its upper end at 44 to the rear end of a primary propeller link 46 which is pivoted at 48 at its approximate midsection to the approximate midsection of secondary drive link 42 which is pivoted at its upper end at 50 to the rearward end of a secondary propeller link 52.
  • Primary propeller link 46 is pivoted at 54 at its forward end to the lower end of a major leg rest drive link 56 which is pivoted at 58 at its approximate midsection to the approximate midsection of secondary propeller link 52 and at its upper end at 60 to one end of a major leg rest support plate 62.
  • the forward end of secondary drive link 42 is provided with a stop surface 43 which is adapted to contact a stop surface 57 on major leg rest drive link 56 to limit the range of extension of the leg rest.
  • a minor leg rest drive link 64 is pivoted at 66 at its lower end to the forward end of secondary propeller link 52 and is pivoted at 68 (see FIG. 3), at its upper end to a minor leg rest support plate 70 which is pivoted to major leg rest support plate 62 at 72.
  • a connecting link 74 is pivoted at 76 at it supper end to major leg rest support plate 62 and at its lower end at 78 to minor leg rest drive link adjacent the forward end of the latter.
  • 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 controls 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.
  • 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 98 and having a central slot 120 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 units 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 140 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 link 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.
  • 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.
  • 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.
