发明名称 Inclined-axis pendulum swing
摘要 An infant swing having a base, upwardly extending legs, and a coil spring-wound motor mounted on said legs, with the axis of said coil spring motor extending at a predetermined angle from the vertical above said base. A carriage is mounted to the motor such that it is driven by and oscillates about the axis of the spring. A swing support rod has one leg removably mounted to said carriage parallel to the axis of the spring, with the other leg extending substantially vertically downward and terminating in a substantially horizontal radle for supporting an infant seat beneath the carriage, whereby the oscillatory motion of the carriage causes the seat to swing in a substantially horizontal arcuate path. The infant seat is removably mounted to said cradle.
