ABSTRACT:
A manual control for controlling the release of a latching mechanism of a piece of motion furniture including a housing to be mounted on the furniture, a lever to be pivotally mounted within the housing, a spring positioned between the lever and housing to urge the lever toward its inactive position, means on the lever to support the spring on the lever during mounting of the lever within the housing and allow release of one end of the spring to engage the housing, a cable sheath structure, an arcuate recess on the lever and having means to connect one end of the cable to the lever, means restricting entry of the cable into said arcuate recess to avoid undesired release of the cable therefrom, means on the housing for receiving one end of the cable sheath, the lever having a handle portion which is sufficiently large to limit the entry of more than the first joint of fingers into the housing below the lever handle, such handle portion having sufficient area on its outer surface to allow a logo to be embossed thereon, and a fixture, such as a Ping-Pong ball, to position in the housing recess under the lever handle to retain it a short distance from its inactive position during connection of the opposite ends of the cable and sheath to the chair latching mechanism to provide the desired amount of overtravel to avoid having to adjust the position of the end of the cable.
