摘要: A retro-fittable, controllably extendable leg rest apparatus for positioning an attached recliner chair leg rest member in retracted or forwardly extended positions. The apparatus includes an elongated frame bracket which may be retro-fittably secured to most conventional scissor linkage assemblies of various recliners. A mounting bracket is included having a first bracket portion secured to the leg rest member, and a second bracket portion having an elongated channel. A plurality of rivets extend through the elongated channel to secure the mounting bracket to the elongated frame bracket. The shanks of the rivets provide guide members upon which the elongated channel of the mounting bracket may slide. A spring is coupled in between a shoulder portion of the mounting bracket and the elongated frame bracket to bias the mounting bracket in a normally retracted position. A latching member is pivotally secured to a portion of the scissor linkage assembly to releasably latch the mounting bracket in the forwardly extended position. The apparatus is extended to the forwardly extended position by applying an outward force to the inner edge of the leg rest member when the scissor linkage is fully protracted, thereby causing the mounting bracket to slide along the shanks of the rivets until the latching member latches with a latching edge surface of the mounting bracket. When the scissor linkage assembly is manually retracted, the latching member is urged out of engagement with the latching edge surface, thus enabling the spring to forcibly return the mounting bracket to and maintain it in the retracted position.
