US Patent 8950020 Bassinet rocking device

An automatic bassinet rocking device imparts a rocking motion to a bassinet or rocking crib. A housing is supported above the rocker base of the bassinet on adjustable legs so that the device straddles the curved rocking base. A reciprocating rod descends from the housing and attaches to a strap or clamp at an anchor point on the rocker base. An oscillatory drive inside the housing imparts a reciprocating motion via the reciprocating rod onto the rocker base.
