US Patent 8484776 Cradle

The present invention disclose a new cradle, including: a cradle frame, with a limiting rod extending along the height set on it; a cradle body, which move up and down along the height of the cradle frame; elastic connecting pieces, which are connected between the cradle frame and the cradle body; a noise reducing component, which includes two parallel mounting plates, two opposite 1st pulleys installed on two mounting plates respectively as well as two opposite 2nd pulleys installed between two mounting plates, wherein the rotating axis of the 2nd pulley is perpendicular to that of the 1st pulley and the limiting rod passes through the clearance enclosed by the two 1st and the two 2nd pulleys, with a mounting plate fixed to the body of the cradle. The up and down reciprocating movement can effectively facilitate the baby's sleep (especially having better effects for babies more than one full year old); at the same time, by adopting the noise reducing device and changing sliding friction to rolling friction, the present invention can effectively reduce the noise and resistance generated during the up-down movement of the body of the cradle, so that the baby's sleep will not be influenced due to noise.
