发明名称 Motorized swing
摘要 A motorized swing is set forth including a spaced plurality of support bases and posts with support shafts horizontally oriented between the posts and securing a child's swing in a suspended fashion therefrom. Adjacent each post and spaced from the swing along the support shaft is a motor housing including a drive motor and gear drive with a downwardly depending pivot control arm directed orthogonally therefrom. Each pivot control arm is formed of a lower "L" shaped arm and an upper linear link, wherein the "L" shaped arm is pivotally mounted relative to the linear link to effect pivoting of the "L" shaped arm relative to the link and enable a varying of the swinging effect when the spaced "L" shaped arms are asymmetrically oriented relative to one another.
