A stroller includes a left side support frame; a right side support frame; and a connecting frame which connects the left and right side support frames together, and which defines a seat rest for a child; wheels rotatably connected to a front and rear of each support frame; at least one rear footboard connected to a rear end of the stroller; an adjustment assembly which rotatably connects the rear wheels to a rear of the support frames, between a first inward operative position and each rear footboard to a vertical position for use when a child is not standing on the at least one rear footboard and a second outward operative position and each rear footboard to a horizontal position which increases a footprint of the stroller for use when a child is standing on the at least one rear footboard.

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 child stroller apparatus includes a first frame portion provided with a first wheel assembly, a second frame portion provided with a second wheel assembly, the second frame portion being assembled with the first frame portion for sliding movement along a lengthwise axis extending from a front to a rear of the child stroller apparatus, and an expandable storage basket spanning across the first and second frame portions. The storage basket includes a first and a second basket frame portion respectively attached to the first and second frame portion, the first and second basket frame portions being movable away or toward each other for expanding or contracting the storage basket as the second frame portion slides relative to the first frame portion for increasing or reducing a distance between the first and second wheel assemblies.

A child stroller apparatus includes a first and a second leg portion, a handle frame, a child seat slidably assembled with the first leg portion, and a linkage. The handle frame has a side segment that is respectively connected pivotally with the first leg portion via a first pivot connection and with the second leg portion via a second pivot connection, the first pivot connection and the second pivot connection respectively defining a first pivot axis and a second pivot axis spaced apart from each other about which the first leg portion and the second leg portion are respectively rotatable relative to the side segment of the handle frame. The linkage is respectively connected with the side segment and the child seat, whereby a sliding movement of the child seat along the first leg portion is linked to a rotation of the handle frame relative to the first leg portion.

A child stroller apparatus includes a first side segment connected fixedly with a first shell portion and a grip portion that are disposed adjacent to each other, a second side segment fixedly connected with a second shell portion that is pivotally connected with the first shell portion, a latch assembled in a cavity delimited at least partially by the first and second shell portions, the latch being movable between a locking position that prevents relative rotation between the first and second side segments and thereby locks the child stroller apparatus in an unfolded state for use, and an unlocking position for folding and unfolding of the child stroller apparatus, and a release actuator assembled adjacent to the grip portion and operatively coupled to the latch, the release actuator being operable to cause the latch to move from the locking position to the unlocking position.

A child stroller apparatus includes a stroller frame, and an adapter assembled with the stroller frame and having a first coupling portion and a second coupling portion, each of the first and second coupling portions being configurable as a mount for installation of a detachable part. The adapter is movable relative to the stroller frame to displace the first and second coupling portions, a first position of the adapter configuring the first coupling portion as the mount while maintaining an angle between the first coupling portion and the second coupling portion, and a second position of the adapter configuring the second coupling portion as the mount while maintaining the angle between the first coupling portion and the second coupling portion.

A child stroller has a frame with a primary seat frame, at least one forward wheel and at least one rear wheel rotatably mounted to the frame, and primary and secondary forward-facing seats operatively supported by the frame. The secondary seat is positioned at least partially behind and at least partially below the primary seat. The stroller is convertible between an in-use configuration for transporting children and a folded storage configuration without removing the secondary seat, with the secondary seat positioned at least partially within the frame when the stroller is in the folded storage configuration. The stroller is configured such that the secondary seat is selectively movable from an in-use position to a storage position without folding the remainder of the stroller such that, following movement of the secondary seat to the storage position, the remainder of the stroller is selectively foldable around the secondary seat.
