Abstract
Provided herein is a baby stroller, which has expanded mode or folded mode, including a lower frame, a slide block, a pull rod set, a rear wheel link rod, a rear wheel frame, an upper arm set, a link rod set, a connection rod set, the first handle rod set, the second handle rod set, and a front wheel frame. Through the slide block and the interaction between each component to concurrently actuate the upper arm set, the first handle rod set, and the second handle rod set, the baby stroller can be easily folded to minimize it occupying space for easier stowing and transporting.
Claims14
A baby stroller with an expanded mode and a folded mode, comprising:
- a lower arm, one end of which is disposed with a connection part, a slide block being disposed on the lower arm, wherein the slide block slides along the lower arm;
- a pull rod set, one end of which is pivotally connected to the slide block;
- a rear wheel frame, one end of which is connected to the connection part and the other end of which is connected to at least one rear wheel, wherein the other end of the pull rod set is connected to a position between both of the ends of the real wheel frame;
- an upper arm set, one end of which is pivotally connected to the connection part;
- a link rod set, one end of which is pivotally connected to a terminal of the upper arm set and the other end of which is pivotally connected to the slide block;
- a first handle rod set, one end of which is disposed adjacently to the other end of the upper arm set and the other end of which is pivotally connected to a joint set;
- a second handle rod set, one end of which is pivotally connected to the joint set;
- and
- a front wheel frame, which is disposed on the other end of the lower arm, wherein the other end of the second handle rod set is pivotally connected to the front wheel frame and at least one front wheel is disposed on the front wheel frame;
- wherein the slide block is adjacent to the connection part in the expanded mode, and the slide block is adjacent to the front wheel frame in the folded mode, and the first handle rod set and the second handle rod set are superposed one another in the folded mode, and an angle between the upper arm set and the lower arm is greater in the expanded mode than in the folded mode, and an angle between the rear wheel frame and the lower arm is greater in the expanded mode than in the folded mode, the upper arm set, the first handle rod set, and the second handle rod set are actuated concurrently while switching between the expanded mode and the folded mode.
