A compact collapsible stroller in accordance with the present disclosure includes a mobile cart and a seat coupled to the mobile cart. The mobile cart includes a rolling base and a foldable frame that fold inwardly and outwardly from the rolling base.

A foldable stroller, comprising a frame (10), at least one leg (16) pivotally mounted at the lower end of the frame (10) and pivotal with respect thereto between an operable configuration in which said frame (10) extends at an angle relative to vertical and said at least one leg (16) extends from the front of the frame (10), and a folded configuration in which said leg (16) is located behind the backrest (200). The stroller further comprises a rear mount (22) extending, in the operable configuration, substantially vertically downward from an intermediate location along the length of the frame (10) and being pivotally mounted to the frame (10) such that, in a fully folded configuration, the rear mount (22) can be pivoted to a position substantially parallel to and behind the backrest (200). A rigid linking arm (28) is secured between the at least one leg (16) and the rear mount (22) such that when the leg (16) is pivoted, corresponding pivoting of the rear mount (22) is effected. A pivot mechanism between the leg (16) and the frame (10) is provided with a lock having an actuator.

A collapsible stroller includes a stroller frame, at least one hinge mechanism, a wheel, and a swivel mechanism. The stroller frame is moveable between a deployed position and a collapsed position. The hinge mechanism allows for movement of the stroller frame between the collapsed position and the deployed position. The swivel mechanism connects the wheel to the stroller frame. The swivel mechanism includes a vertical axle, a cam follower, and a cam. The vertical axle connects with the wheel and is rotatable with respect to the stroller frame about a vertical axis. The cam follower is fixed to the vertical axle. The cam includes a sloped cam surface at least partially surrounding the vertical axle. The sloped cam surface contacts the cam follower to move the cam follower along the sloped cam surface, which results in rotation of the vertical axle about the vertical axis.

A folding stroller having a frame that can be arranged in at least a first configuration and a second configuration, the frame including a handgrip fixedly connected to an upper joint, a lower joint pivotally connected to the upper joint, the lower joint being fixedly connected to a front tube, a rear joint pivotally connected to the lower joint, the rear joint being fixedly connected to a rear tube, and a joint connecting rod connected to the lower joint, the rear joint, and the upper joint, wherein a distance between the upper joint and the rear joint is larger than a predefined threshold while the frame is in the first configuration, while the frame is in the second configuration, and while the frame is transitioning between the first configuration and the second configuration.

Disclosed is a folding stroller, comprising a stroller frame, a front wheel assembly (20) and a rear wheel assembly (30), and a locking mechanism provided on the stroller frame and used for locking the stroller frame, and the stroller frame comprises a front support (1), a rear support (2) and a seat rod (3); the front support (1), the rear support (2) and the seat rod (3) are connected with one another to form a triangular three-link mechanism; in the three connection relationships among the three components, two are rotatable connection, and the rest one is relative slidable connection by means of a slider (4), and the slider (4) is slidably arranged in the length direction of one of the two connected components and is in rotatable connection with the other component. The stroller can be conveniently folded, has a simple structure, and has good rigidity when unfolded.

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.

An infant stroller apparatus includes a front leg frame having a first side segment, a handle frame having a second side segment pivotally coupled with the first side segment via a first pivot connection, a rear leg frame having a third and a fourth side segment pivotally coupled with each other via a second pivot connection, the third side segment being further pivotally coupled with the first side segment via a third pivot connection, and the fourth side segment being further pivotally coupled with the second side segment via a fourth pivot connection, a seat portion pivotally coupled with the first side segment via a fifth pivot connection, and a support frame portion respectively coupled with the seat portion and the fourth side segment.

Disclosed are a foldable joint having an unfolded position and a folded position, and a stroller having the foldable joint. The foldable joint comprises a base rod (1), a first rotary rod (2) and a second rotary rod (3), wherein one end portion of the base rod (1), one end portion of the first rotary rod (2) and one end portion of the second rotary rod (3) are rotationally connected to one another, a slider (4) is slidably arranged on the base rod (1), a driving part (41) is connected to the slider (4), a first guide portion (21) is arranged on the first rotary rod (2), a second guide portion (31) is arranged on the second rotary rod (3), and the driving part (41) is slidably fitted with the first guide portion (21) and the second guide portion (31) respectively. In the process of unfolding or folding the foldable joint, the driving part (41) moves relative to the first guide portion (21) and the second guide portion (31) simultaneously, and the driving part (41) moves along with the slider (4) relative to the base rod (1) such that the three components, i.e. the first rotary rod (2), the second rotary rod (3) and the base rod (1) are rotated relative to one another.
