A basket is detachably mounted on a first mount of a carrier for allowing an infant car seat to be mounted on the carrier. The first mount has a first mounting slot. The basket includes a basket body and a mounting structure. The mounting structure is connected to a side of the basket body. The mounting structure has a body portion, an inserting portion and a mounting portion. The body portion is connected between the mounting portion and the inserting portion. The infant car seat is suspended on a storage space of the basket body when the inserting portion is inserted into the first mounting slot and the infant car seat is mounted on the mounting portion.

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.

The disclosure provides a stroller frame locking mechanism and a stroller having the same. The stroller frame comprises a stroller handle, a front wheel bracket, and a rear wheel bracket, both the front wheel bracket and the rear wheel bracket being pivotally connected to the stroller handle. The stroller frame locking mechanism comprises: a support assembly supported between the front wheel bracket and the rear wheel bracket, the support assembly comprising a first support member and a second support member pivotally connected to each other, the first support member being pivotally connected to the front wheel bracket, and the second support member being pivotally connected to the rear wheel bracket; and a locking device arranged to lock or unlock the support assembly, such that the first support member and the second support member is unable to pivot or able to pivot in respect to each other.

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.

A stroller frame having forwardly extending right and left side front supports, rearwardly extending right and left side rear supports, and upwardly extending right and left side handle supports moveable connected to permit movement of the frame between deployed and collapsed orientations, and a downwardly folding seat frame connected to the front and rear supports having right and left side fold mechanisms which are configured to lock the frame in the deployed configuration, apply a biasing force to fully deploy the seat frame during the unfolding movement, and isolate the biasing force while applying a folding force to the seat frame during the folding operation, actuation of the fold mechanisms based on frame orientation and position of a release handle.

A foldable stroller includes a main frame, a support unit, two fixed side units, two movable side units, and a guardrail. The main frame includes two joints, two upper connectors, a handlebar, two lower connectors, a lower bar and two front wheels. Each of the two fixed side units includes a leg, a first locking member, a first spring, a fixed block, a release member, a ramp, a pull handle, a second spring, a wheel support and a rear wheel. Each of the two movable side units includes a movable block, a press knob, an extension, a second locking member, a third spring and two braces. Thus, the first locking member and the second locking member construct a two-stage locking mechanism, to lock the stroller steadily, thereby preventing the stroller from being folded accidentally.

A stroller includes a stroller frame, a frame locking mechanism, and a seat. The stroller frame can be folded or unfolded. The frame locking mechanism locks the stroller frame to be unfolded. The seat is pivotally connected to the stroller frame and is connected to the frame locking mechanism. Therein, when the seat pivots, the seat drives the frame locking mechanism to unlock the stroller frame so as to fold the stroller frame. The stroller is structurally simple and is convenient to be folded.

The present disclosure provides a stroller capable of being folded twice, comprising: side support assemblies located at two sides and at least one transverse brace connected between the side support assemblies of the two sides, the side support assembly at each side comprises a push rod, a front wheel support and a rear wheel support which are rotatably connected to each other, and in a first folded state, the push rod, the front wheel support and the rear wheel support are rotated to be in a closed state; each transverse brace has a first transverse folding rotation point and a second transverse folding rotation point. The stroller is capable of achieving not only a first folding, but also a second folding of the two side support assemblies, so as to reduce the volume occupied by the entire stroller in these states.
