Description

Folding structure of baby stroller

The invention relates to a baby stroller, in particular to a folding structure capable of folding a baby stroller to reduce the volume and facilitating collection, storage and transportation.

The four-wheeled strollers currently available on the market can be roughly divided into two types, one of which is a stroller that can simultaneously fold horizontally and vertically. For example, Taiwan Certificate No. M474677 "Baby Stroller Structure", No. M319208 No. M407192 "Pedal Cartridge Folding Device" patent case, which is usually composed of a soft foldable fabric with a skeleton; the other is only Baby strollers capable of longitudinal folding, such as Taiwan Certificate No. I429550 "Retractable Stroller", No. M312478 "Baby Stroller Skeleton" and M288610 "Baby Stroller Skeleton Structure" Patent Case Because the stroller does not need to be laterally retracted, the seat is usually a hard-shell structure. Sometimes the seat is designed to be separated from the cart body for consumers to make different needs according to their needs. Use mode.

In the above-mentioned baby stroller which can only be longitudinally folded, it can only fold the body of the cart skeleton at the time of folding, and does not have the interlocking fit for the front wheel to further reduce the effect of the folded volume, and Some carts must even be removed from the seat in the folding, causing troubles in use.

Nowadays, the main object of the present invention is to provide a stroller that can be used to simultaneously fold the front wheel set when folding, and does not need to remove the seat when folding, but is more convenient to use. Folded structure.
