ABSTRACT:
An article of furniture has a mechanism for supporting an extendible legrest. The mechanism includes a fixed bracket mounted near the front rail of the furniture frame, an upper rear link connected to the fixed bracket at a first pivot in front of the front rail, a lower rear link connected to the fixed bracket at a second pivot under the front rail, an upper front link connected to the upper rear link at a third pivot, and a lower front link connected to the lower rear link at a fourth pivot which is lower than the third pivot. A movable legrest bracket is connected to the upper front link at a fifth pivot, and is also connected to the lower front link at a sixth pivot. The sixth pivot is lower than the fifth pivot when the movable legrest bracket is at its stored position. The upper front link is connected to the lower rear link at a seventh pivot which is lower than the third pivot and is between the second and fourth pivots. Two such mechanisms are connected together by torsion members so they extend and retract simultaneously, and these torsion members are housed in a space beneath the front rail when the mechanism is in its retracted position.
