A stroller with a pivotable front wheel assembly. When folding the stroller, the front wheel assembly may pivot, exposing a flat surface which may be rested on the ground for easier storage of the stroller. A drive rod may drive the front wheel assembly to rotate during folding. A slider may move away from the front wheel assembly during folding, moving a rear tube into place and ultimately causing the drive rod to drive the front wheel assembly to rotate. A lock mechanism may be included to lock the frame into configuration.

A collapsible stroller includes a stroller frame moveable between a deployed position and a collapsed position and a latch mechanism. The stroller frame includes a first leg, a second leg and a handle support member. The handle support member is pivotable with respect to the first leg or the second leg. The latch mechanism includes a latch body and a catch. The latch body is positioned internally of the second leg. When the stroller is in the deployed position, the latch body is blocked from view by the second leg when the stroller frame is viewed in a side elevation view. The catch is provided on or connected with the first leg or the handle support member. The latch body cooperates with the catch to selectively connect the latch body with the catch when the stroller is in the collapsed position.

A collapsible stroller includes a stroller frame, at least one hinge mechanism, and a hinge lock mechanism. The stroller frame is movable between a deployed position and a collapsed position. The at least one hinge mechanism is on the stroller frame and allows for movement of the stroller frame between the collapsed position and the deployed position. The hinge lock mechanism is capable of a locked state and an unlocked state. In the locked state, the hinge lock mechanism locks the at least one hinge mechanism to maintain the stroller frame in the deployed position. In the unlocked state, the hinge lock mechanism allows the stroller frame to move from the deployed position toward the collapsed position. The hinge lock mechanism includes a manually actuated first linkage and a manually actuated second linkage.

The application discloses a frame of double-person baby carriage and a frame folding mechanism thereof. The frame folding mechanism comprises an upper link, a lower link, a middle upright rod, two upper supporting rods, two lower supporting rods and two foot frames.

A child carrier is provided and includes a frame, a seat and a folding device. The frame includes a handle, a first leg and a second leg. The first leg is pivotally connected to the handle. The second leg is pivoted to the handle. The folding device is installed between the frame and the seat. The folding device includes a sliding structure and a linking component. The sliding structure is fixedly disposed on the handle. The seat is slidably coupled to the sliding structure. The linking component includes a first end and a second end. The first end is pivotally coupled to the seat. The second end is pivotally connected to the second leg.

A child stroller apparatus includes a first leg frame having a first side segment, a second leg frame having a second side segment, a handle frame having a third side segment, a seat assembly coupled to the first side segment, and a linkage including a support bar, a slider and a frame link. The third side segment is respectively connected pivotally to the first side segment and the second side segment, wherein the third side segment is pivotally connected to the first side segment via an articulation. The support bar is respectively connected pivotally to the first side segment and the second side segment, the slider is coupled to the seat assembly and is slidably connected to the support bar, and the frame link is pivotally connected to the slider, the slider sliding along the support bar during folding and unfolding of the child stroller apparatus.

A frame structure and a baby stroller are provided. The frame structure includes a hand-gripping part; a front leg pivotally connected with the hand-gripping part; a rear leg pivotally connected with the hand-gripping part; a seat bracket; and a fixing seat slidably disposed on the front leg for connecting the seat bracket to the front leg. The fixing seat is configured to, in response to the rear leg and the front leg approaching or moving away from each other, move from a first position of the front leg to a second position of the front leg.

A stroller includes a frame having an unfolded configuration and a folded configuration, the frame has a virtual plane perpendicular to a horizontal plane, a first wheel assembly, a second wheel assembly and a third wheel assembly are disposed below a front portion of the frame, the second wheel assembly and the third wheel assembly are symmetrically arranged relative to the virtual plane. The frame includes: a seat frame configured to be connected with a seat for sitting a child; a front support, wherein the first wheel assembly is disposed at a lower portion of the front support. A rear support includes a left rear support and a right rear support symmetrically arranged relative to the virtual plane, the left rear support and the right rear support are slidably connected to the seat frame respectively.

A stroller frame has a push-pull function consisting of a lower supporting frame and an upper frame connected through a frame joint. The lower supporting frame comprises a front leg connected to a front wheel set and a rear leg connected to a rear wheel set. The lower portion of the front leg is pivotally attached to a pull rod assembly located at the front of the stroller frame. In addition, a push rod assembly is connected to the lower supporting frame and extends diagonally toward the rear of the stroller frame to allow the user to push the stroller frame in a raised position while walking, which facilitates pulling or pushing the stroller frame as desired while also allowing interaction with the child riding on the upper frame. The stroller frame is characterized by its ease of use and versatile functionality.
