Abstract:
A footrest of a reclining chair, comprisinga footrest part pivoted to a front portion of a seat of a reclining chair; and an adjusting mechanism joined to a frame of the chair, on which the seat is supported; the adjusting mechanism including: a pivotal shaft passed through first and second lateral portions of a lower part of the frame respectively at first and second ends thereof; two pairs of first and second connecting rods used for passing on movement of the pivotal shaft to the footrest part; the first rods being securely joined to the pivotal shaft; the second rods being each pivoted to a corresponding first rod, and pivoted to the footrest at two ends; the footrest part being movable between a completely stretched position and a retreated one by means of causing rotation of the pivotal shaft to displace the first and the second connecting rods; a third connecting rod pivoted on a first end of the pivotal shaft; a detaining member secured to the first lateral portion of the frame with the first end of the pivotal shaft being passed through a hole thereof; the detaining member having a plurality of ratchet teeth on an edge; an engaging member pivoted on the third rod for releasable engagement with the ratchet teeth of the detaining member; the engaging member having an engaging portion, and a rod-shaped pressed portion; a first elastic element joined to the third rod, and the engaging portion of the engaging member at two ends thereof for making the engaging member biased to such a position as to engage the detaining member; a first control for displacing the footrest part with; the first control including a pedal portion, and a flat portion securely joined to the pedal portion; the flat portion being joined to the first end of the pivotal shaft such that the first control is angularly displaceable together with the pivotal shaft; the flat portion having a pivotal hole thereon, and two stopping posts located apart on an inward side thereof; a second control made in a form of a pedal for displacing the footrest part with; the second control having an elongated flat portion positioned between the detaining member and the first control plus between the stopping posts of the first control; the elongated flat portion having an up-facing notch, and a pivotal portion; the second control being pivoted to the pivotal hole of the first control at the pivotal portion thereof; and a second elastic element joined to the flat portion of the first control, and the second control member at two ends thereof for biasing the second control in such a way that the up-facing notch is away from the rod-shaped pressed portion of the engaging member; the ratchet teeth of the detaining member being in such a direction that the engaging member won't engage them when the pedal portion of the first control is being depressed; an edge of the notch of the second control being going to be pressed against the rod-shaped pressed portion of the engaging member to make the engaging member disengage the ratchet teeth when the second control is being depressed, and angularly displaced; thus allowing the footrest part to be angularly displaced to, and secured in a stretched position by means of depressing the pedal portion of the first control, and allowing the footrest part to be retreated from a stretched position by means of depressing the second control to angularly displace same.
