Abstract: A stroller frame structure includes a front wheel rack, a rear wheel rack, a first linkage assembly, a coupling dock, a handle tube, a release mechanism, an armrest and a second linkage assembly that are pivotally coupled with one another. The handle tube has a lower end movable to allow the second linkage assembly to drive the first linkage assembly to move downwards to form a V-shaped folding thereby to move the front wheel rack and the rear wheel rack close to each other or extend to achieve smooth folding.

Abstract: An adjustable serving tray mainly includes an anchor apparatus located on armrests at two sides of a stroller. Each armrest has an inner side with a retaining flute formed thereon. The serving tray has coupling sections on two sides, each with an anchor trough and a latch lug. In normal usage conditions, the anchor trough engages with the anchor apparatus and the latch lug is latched in the retaining flute to anchor the serving tray. By releasing the anchor apparatus, the serving tray may be slid forwards to form a larger entrance space on the stroller to seat a child. Thus the child may be seated on the rear seat without removing the serving tray to improve convenience of use.

Abstract: A portable infant carrier includes a basin-shaped base having a mattress pad laid thereon for carrying a baby, and a first plate and second plate pivotally mounted on the base. The first and second plates are selectively movable between a position to cover the base, and a position where the first plate is inclined for the baby to lean on. The mattress pad also serves as a partition under which some baby articles, such as milk bottles or nipples, can be stored.
