Abstract
Provided herein is a baby stroller, which has an expanded mode and a folded mode, and includes a lower arm set, a connection part, a front wheel frame, a slide block, a rear wheel set, an upper frame, a first link rod set, a handling tube, a supporting rod set, two seat supports, and two second link rods. Due to the couplings between the slide block, the handling tube and the upper frame and the coupling between the slide block and the rear wheel rocker arms, the baby stroller may easily be folded so that it occupies considerably less space, and thereby improve its portability and facilitate its stowage and transportation.
Claims6
A baby stroller having an expanded mode and a folded mode, comprising:
- a lower arm set, one end of which is connected to a connection part and the other end of which is connected to a front wheel frame, wherein at least one front wheel is disposed on the front wheel frame and a slide block is disposed on the lower arm set and the slide block is actuated to slide along the lower arm set;
- a rear wheel set, one end of which is connected to the connection part, and other end of which is connected to the slide block;
- an upper frame, one end of which is pivotally connected to the connection part;
- a first link rod set, one end of which is pivotally connected to the slide block, wherein a point between the ends of the first link rod set is pivotally connected to a point between the ends of the upper frame;
- a handling tube, one end of which is pivotally connected to the other end of the upper frame;
- a supporting rod set, one end of which is pivotally connected to the other end of the first link rod set and the other end of which is pivotally connected to the handling tube;
- two seat supports, one end of each being individually and pivotally connected to each of two sides of the connection part, and one opposite end of each being individually supporting a seat;
- and
- two second link rods, one end of each being individually and pivotally connected to one of two sides of the slide block and the other opposite end of each being individually and pivotally connected to each of the two seat supports between two opposite ends of each of the two seat supports, and the two second link rods being configured without connecting to the upper frame;
- wherein:
- a location of the slide block is closer to the connection part in the expanded mode and the location of the slide block is closer to the front wheel frame in the folded mode,
- an angle between the upper frame and the lower arm set is greater in the expanded mode than in the folded mode,
- an angle between supporting rod set and the first link rod set is greater in the expanded mode than in the folded mode,
- an angle between the rear wheel set and the lower arm set is greater in the expanded mode than in the folded mode, and
- an angle between each of the two seat supports and the lower arm set is greater in the expanded mode than in the folded mode.
