Abstract
A rocker conversion unit for affixing rockers to an ordinary molded plastic lawn chair, wherein the unit has an upwardly curved channel shaped rocker the sides of which have an inwardly extending lip providing a first shoulder downwardly facing and adapted to provide a stop for preventing withdrawal of structure upwardly from the channel, a block slidable within the channel and having a second and upwardly facing shoulder extending along each side edge thereof and adapted to engage the first shoulder and be stopped in its upward movement thereby, the block having a height dimension from its bottom to its second shoulder which is less than the base-to-shoulder height dimension of the channel to provide a space in which a lateral foot segment of a molded lawn chair leg can be positioned, and wherein the block further has a manually operable pressure portion adapted to simultaneously force a lower portion of the block downwardly against the foot segment and to force the second shoulder upwardly against the first shoulder whereby the foot segment is rigidly, frictionally locked in position against the bottom of the channel and the rocker is stabilized on the chair.
