Abstract
A foldable jogging stroller frame with an auto-swiveling mechanism for rear wheel sets thereof without return-springs, in which the foldable jogging stroller frame may include a front strut, a pair of push arms pivoted with the front strut by a pair of lockable joints, a pair of rear struts pivoted to the pair of push arms, a seat support rods pivoted between the front strut and the rear struts, and the auto-swiveling mechanism includes at least two sets of swivel sleeve assemblies, a pair of rear sets and a pair of connecting elements. While the pair of push arms is rotating, the association of the connecting elements shall cause the sleeves and the rear sets to swivel in ninety degrees (90°) from the longitudinally traveling direction to a transversally stowing direction thereby achieving a compact configuration for storage.
