Description
- The present invention relates to a stroller and, more particularly, to an assembly-type toy stroller that can be easily and quickly assembled and dismantled.
- Toy strollers generally include two handles, a frame, and a plurality of wheels. The frame is generally foldable to allow easy carriage and storage. Furthermore, the frame generally includes movable and lockable joints so that the toy stroller can be retained in a folded state or an extended state. However, the frame may fold due to accidental impact to the joints, such that a child playing the toy stroller may be injured due to falling or being impinged by the frame. U.S. Pat. No. 5,845,925 discloses a safety device mounted to the rear tubes of the stroller to avoid unintentional folding. However, the stroller has many parts and, thus, has high costs in manufacturing and assembly. Furthermore, a large number of rivets are utilized to pivotably connect the parts, which not only weaken the structural strength of the parts in the pivotal connections but complicate the processing procedures.
- Thus, a need exists for a toy stroller that has fewer parts without sacrificing the structural strength while having a smaller volume for transport.
- The present invention solves this need and other problems in the field of toy strollers by providing, in a preferred form, a toy stroller including first and second bottom tubes each including first and second ends and an intermediate portion between the first and second ends. The bottom tubes are cross hinged at the intermediate portions thereof. The toy stroller further includes first and second rear tubes each including first and second ends and an intermediate portion between the first and second ends. The rear tubes are cross hinged at the intermediate portions thereof A rear wheel unit is coupled to the lower end of each rear tube. The toy stroller further includes first and second connecting members each including a first tube, a second tube extending outward from an outer periphery of the first tube, and a third tube extending outward from an outer periphery of the second tube. The first tube of the first connecting member is fixed to the second end of the first rear tube. The first tube of the second connecting member is fixed to the second end of the second rear tube. The first end of the first bottom tube is detachably mounted in the second tube of the second connecting member. The first end of the second bottom tube is detachably coupled with the second tube of the first connecting member. The toy stroller further includes first and second handle tubes each including upper end lower ends. A handle is fixed to each handle tube. The toy stroller further includes first and second engaging members each including a first tube and a second tube extending from an outer periphery of the first tube. The first tube of the first engaging member is fixed to the upper end of the first handle tube. The first tube of the second engaging member is fixed to the upper end of the second handle tube. The first end of the first rear tube is detachably coupled with the second tube of the second engaging member. The first end of the second rear tube is detachably coupled with the second tube of the first engaging member. The toy stroller further includes first and second sleeves each including first and second receptacles. The lower end of the first handle tube is fixed in the first receptacle of the first sleeve. The lower end of the second handle tube is fixed in the first receptacle of the second sleeve. The toy stroller further includes first and second front legs each including an upper section, a lower section, and an intermediate section between the upper and lower sections. A front wheel unit is coupled to the lower section of each front leg. The upper section of the first front leg is detachably mounted in the second receptacle of the first sleeve. The upper section of the second front leg is detachably mounted in the second receptacle of the second sleeve. The toy stroller further includes first and second coupling members each including a first tube and a second tube extending outward from an outer periphery of the first tube. The first tube of the first coupling member is fixed around the intermediate section of the first front leg. The first tube of the second coupling member is fixed around the intermediate section of the second front leg. The second end of the first bottom tube is detachably coupled with the second tube of the first coupling member. The second end of the second bottom tube is detachably coupled with the second tube of the second coupling member. A left end of a fixing tube is detachably coupled with the third tube of the second connecting member. A right end of the fixing tube is detachably coupled with the third tube of the first connecting member.
