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.

Abstract: A jogging stroller frame with a front wheel automatic flattening folding mechanism is provided with a jogging stroller frame which can be folded into a substantially flattened configuration for compact storage by an associating of a linking rod. When the foldable jogging stroller frame is folded into the substantially flattened configuration, the seat support rack shall pull the front wheel set to rotate backward about a horizontal axis to the pair of rear struts through the linking rod, thereby converting the foldable jogging stroller frame into a successively smaller size for more compact storage.

Abstract: A jogging stroller frame with a wheels automatic flattening folding mechanism is disclosed, which includes a foldable frame, a front wheel set, a pair of rear wheel sets and a driving mechanism. The driving mechanism is associated with the foldable frame for pivoting the front and rear wheels about 90 degrees away from the longitudinal direction automatically during the jogging stroller frame is converting into its folded configuration for storage.

Abstract: A pivot joint for a baby carrier for locking a baby carrier in an in-use configuration and convertible into a foldable condition, includes a first pivot part, a second pivot part, a locking mechanism, a release mechanism and a retaining mechanism. The first pivot part and the second pivot part are pivotally connected between a first support member and a second support member of the baby carrier. The locking mechanism comprises a latch element operatively mounted inside the first pivot part and can be driven to a latched position to engage with the second pivot part and a released position to disengage from the second pivot part. The release mechanism is associated with the latch element for moving the latch element from the latched position to the released position. The retaining mechanism is mounted inside the first pivot part for engaging and retaining the latch element in the released position.

Abstract: A foldable baby carrier support includes a front rack, a rear rack and a locking mechanism. The front rack has a pair of front side struts extending through a front side of the foldable baby carrier support; the pair of front side struts each has a rear downward extension bended from the front side to the rear side of the foldable baby carrier support, and the rear downward extensions each has a pivot portion at its distal end. The rear rack includes a pair of rear side struts, each being equipped with a pivot mounts for pivoting the rear downward extensions at the pivot portions. The locking mechanism is adopted to lock and unlock the pivot mounts so as to lock the foldable baby carrier support in an erected configuration, and unlock the foldable baby carrier support to be foldable into a folded configuration.
