Abstract

A foldable stroller wagon (3) includes a frame set (31) where a holding set (32) and at least one seat set (33) are respectively disposed. The frame set (31) includes two main frames (310, 311), a first acting member (313) disposed between the main frames (310, 311), and a positioning slot (316) formed in the main frames (310, 311). The holding set (32) includes a bottom base (320), a handle unit (321) pivotally disposed on the bottom base (320), a second acting member (322) slidably disposed on the bottom base (320) and connected to the first acting member (313), and a third acting member (323) disposed on the handle unit (321) . Accordingly, an action of swinging the handle unit (321) to a floor plate (330) of the seat set (33) forces the third acting member (323) to move the second acting member (322) . The movement of the second acting member (322) causes the first acting member (313) to withdraw from the positioning slot (316) for unlocking the main frames (310, 311), thereby folding the stroller wagon (3) easily and quickly.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a stroller and relates particularly to a foldable stroller wagon. 2. Description of the Related Art A baby stroller is considered as one of the most practical baby products because it is usable from a newborn period to a kindergarten period if certain conditions are satisfied. A baby stroller is helpful not only in daily life but also in short or long journey. Different types of baby strollers are applicable to different occasions to thereby meet different requirements. A baby stroller also assists in relieving the burden on parents, allowing babies to have comfortable experience when going out, and training babies to be independent. Therefore, baby raising can be easier when a baby stroller is properly used before the baby can walk independently. When consumers choose a baby stroller, one of the priorities for consumers is that whether the baby stroller can be quickly folded and unfolded. A foldable baby stroller is not only convenient for transportation, carrying and storage, but also suitable for parent who often takes care of their baby alone. However, folding and unfolding operations of a conventional foldable baby stroller are generally complicated and difficult. Multiple steps are required in order to properly fold or unfold the baby stroller, and that is time-consuming and inconvenient. Further, in order to make the baby stroller lighter, its weight and volume are reduced, and that will also reduce the seating space for babies, affect the seating comfort, and cause the poor moving stability, and that require to be improved. SUMMARY OF THE INVENTION The object of this invention is to provide a foldable stroller wagon capable of simplifying folding and unfolding operations, saving time and labor for executing the aforesaid operations, providing enough space for use, increasing the moving stability, and improving the seating comfort. The foldable stroller wagon of this invention comprises a frame set, a holding set and at least one seat set respectively disposed on the frame set. The frame set includes two main frames, a plurality of wheels installed below the main frames, a positioning slot formed inside the main frames, and a first acting member movably installed between the main frames. The holding set includes a bottom base installed on any one of the main frames, a handle unit pivotally connected to the bottom base, a second acting member movably installed on the bottom base and connected to the first acting member, and a third acting member installed on the handle unit and located relative to the second acting member. The seat set includes a floor plate, a sealing plate connected to the floor plate, two handrails pivotally installed on at least one main frame and located in opposing relationship, and a back plate installed between the handrails. During a folding operation, the back plate and the handrails are swung to the floor plate. The handle unit is then swung to the floor plate so that the third acting member is forced to push the second acting member by the swinging action of the handle unit. The movement of the second acting member then forces the first acting member to withdraw from the positioning slot so that the main frames are unfixed and capable of being folded. Thus, the folding operation is easy and simplified, thereby reducing the time and labor expended on the folding operation. The foldable stroller wagon helps reduce the occupied space after being folded. Further, the foldable stroller wagon is provided with a stable structure and sufficient space for seating or storing after being unfolded, thereby improving the moving stability and improving the seating comfort. Preferably, the frame set includes a first limiting member disposed on one of the main frames, a second limiting member disposed on another one of the main frames and located beside the first limiting member, and a first elastic member disposed on the second limiting member. The positioning slot is formed between the first limiting member and the second limiting member. The first acting member is pushed into the positioning slot by an elasticity of the first elastic member. Preferably, a limiting unit is disposed on the first limiting member. A limiting slot is formed on the second limiting member. The limiting unit is adapted to be engaged with the limiting slot, thereby strengthening an engagement between the main frames. Preferably, the holding set includes a sliding slot recessedly formed into the handle unit, at least one locking slot formed on a periphery of the sliding slot, a fastening unit disposed on the handle unit, a second elastic member connected to the fastening unit, a locking unit penetrated through the fastening unit, and a functional unit disposed on the handle unit and connected to the fastening unit. The fastening unit is pushed by an elasticity of the second elastic member, and the locking unit is embedded in the lock
