The present disclosure relates to a twice-foldable stroller including: a frame main body 100 which is configured to have right and left front-angle frames 101 to support front wheels 101a and a horizontal frame 101 connected at a lower part between the right and left front-angle frames 101, right and left rear-angle frames to support rear wheels 102a and connecting frames 102 connected between the right and left rear-angle frames 102 and the right and left front-angle frames 101, and vertical frames 103 connected to the right and left connecting frames 102; seat frames 200; backrest frames 300; support frames 400; extension frames 500; canopy frames 600 and 600 rotatably connected to the extension frames 500 for sunshade; and handles 700 and 700, each connected to the extension frames 500 wherein right and left central portions are rotatably connected to each other, wherein each of the front wheels 101a and the front-angle frames 101 are rotatable via rotational axes R1 and R2, the front-angle frames 101 and the extension frames 500 are rotatable via rotational axes R3 and R4, and the handles 700 and 700 are rotatable via a rotational axis R5, which is a useful invention which is advantageous in that it significantly reduces the volume of a stroller by folding it twice, in which the stroller is folded again vertically when being in a horizontally folded state, and since it has a simple structure, it is possible to easily manufacture at a low cost as well as convenient to use, and can be used stably long term without breaking, which is economical and long lasting.

A collapsible stroller is disclosed, including a front axle frame member, a rear axle frame member, a handlebar frame member, a handlebar, and a hub. The hub includes a rotating attachment point for the front axle frame member, a rotating attachment point for the handlebar frame member, a fixed attachment point for the rear axle frame member. A cable connects the hub, and a rotatable handle on the handlebar frame member. When the rotatable handle is rotated, the cable causes the hub to collapse in two stages.

A collapsible stroller includes a stroller frame, a folding lock mechanism, a lateral lock mechanism, and a trigger mechanism. The stroller frame includes a right upper side frame member pivotally connected with a right lower side frame member and a left upper side frame member pivotally connected with a left lower side frame member. The folding lock mechanism is capable of a locked state and an unlocked state. The lateral lock mechanism is capable of a locked operating state and an unlocked operating state. The trigger mechanism is on the stroller frame, and actuation of the trigger mechanism moves the folding lock mechanism from the locked state to the unlocked state and moves the lateral lock mechanism from the locked operating state to the unlocked operating state.

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.

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 bearing structure includes a wheel assembly defining a first front wheel assembly and a second rear wheel assembly, the rear wheel assembly including at least two wheels spaced by a first width defining a first position; wheel supports connecting the axes of rotation of the wheels with the bearing structure; a first folding device enabling a first folding causing a reduction in spacing between the two rear wheels to a second width lower than the first width, defining a second position. A connection system, connecting the wheel supports of the first and second assemblies to the first folding device, enables a second folding of the wheels so as to allow a rotation substantially equal to 90 of the wheels in the horizontal plane when the wheels are in the second position.

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 collapsible stroller with bouncing seat comprises a frame, four sets of wheels, handles that extend upwards so that an adult can push the device, and a seating area that allows the seated child to push their feet against a surface for leg exercise and fun. In addition the collapsible stroller with bouncing seat comprises a play center, cup holder, a set of utility hooks, and a mesh storage bag. The collapsible stroller with bouncing seat collapses for easier storage when not in use.

A child stroller apparatus includes a handle frame having a first side segment, a first leg frame having a second side segment, a second leg frame, a linkage assembly connected with the handle frame and the second leg frame, and a latching mechanism. The second side segment is connected with a joining part, and the first side segment is connected pivotally with the joining part. Moreover, a handle is disposed adjacent to the joining part and connected with the joining part. The latching mechanism includes a latch assembled with the second side segment, and a release actuator assembled adjacent to the handle and operatively connected with the latch. The latch can engage with the linkage assembly for locking the child stroller apparatus in an unfolded state, and the release actuator is operable to urge the latch to disengage from the linkage assembly for folding the child stroller apparatus.

A foldable stroller (1, 41) is provided with at least one pushrod (2, 3) being pivotable about a first pivot axis (9, 10). The folding mechanism is further provided with a number of rods, comprising a first rod (19, 20) being pivotable about a second pivot axis (17, 18). The first rod and the pushrod are provided with cooperating connecting elements (52, 56) being connectable to each other by pivoting the pushrod about the first pivot axis to an erect position of the pushrod, in which position the connecting elements are lockable to each other by locking means (57). When the locking means are unlocked and the connecting elements are still connected to each other, the connecting means prevent the first rod to pivot about the second pivot axis. After unlocking the locking means as well as after disconnecting the connecting elements by pivoting the pushrod about the first pivot axis towards a collapsed position of the pushrod, the first rod is pivotable about the second axis to achieve the collapsed position of the stroller.
