CA 2275105

A swing drive mechanism is provided for use with infant's and child's swings. The swing drive mechanism provides an input mechanism, an output mechanism, and a torsion spring member disposed between the input mechanism and the output mechanism. The torsion spring member includes a first portion and a second portion which interact together to produce a desirable spring gradient while also reducing the overall length of the torsion spring member. The torsion spring member is secured into attachment with the input mechanism by a novel securement mechanism. The output mechanism includes an axle and a drive flange. Preferably, the features of the input mechanism, the output mechanism, and each portion of the torsion spring member are integrally formed.
