Embodiments include strollers having removable seats. An example stroller may include rear wheels, front wheels, and a frame including a handle portion, a rear wheel support portion, a front wheel support portion and a folding mechanism connecting the front wheel support portion and the handle portion in both an unfolded configuration and in a folded configuration. The frame may include a stroller seat support portion positioned at a first vertical position adjacent the handle portion, and a front seat attachment configured for attachment to the front wheel support portion at a second vertical position substantially lower than the first vertical position. The front seat attachment may be configured to support the front stroller seat substantially over the front wheels so that a center of gravity of the stroller system is between the front wheels and the rear wheels.

A support anti-breaking structure includes a first plate member (1), a second plate member (2) and a first fixing member (3). An end of the first plate member (1) is pivotally connected to an end of the second plate member (2) at a first pivotal connection (51). The first fixing member (3) is formed by a flexible structure and fixed to a side of the first pivotal connection (51). The first plate member (1) and the second plate member (2) can press the first fixing member (3), so that the first plate member (1) and the second plate member (2) can be rotatably folded. When the first plate member (1) rotates relative to the second plate member (2) in a direction of pulling the first fixing member (3), the first fixing member (3) will exert reaction force to the first plate member (1) and the second plate member (2) by structural strength itself, thereby restraining the rotation of the first plate member (1) relative to the second plate member (2), so as to effectively reduce the probability of breaking the first pivotal connection (51) due to incorrect operation of the rotation and folding.

A pivot joint includes a first joining part, a second joining part and a coupling part pivotally connected with one another, the second joining part being disposed between the first joining part and the coupling part, a latch carried with the second joining part, and a linking mechanism configured to couple the latch to the first joining part so that a rotation of the first joining part relative to the second joining part in a first direction causes the latch to disengage from the coupling part for rotation of the second joining part relative to the coupling part, and a rotation of the first joining part relative to the second joining part in a second direction causes the latch to engage with the coupling part to prevent rotation of the second joining part relative to the coupling part. Moreover, a child stroller apparatus is also described herein.

The invention relates to a children's vehicle having a vehicle body (10) on which are mounted a front wheel (31) and at least one rear wheel (32), a steering sub-assembly (20) having a steering column (21) linked to the front wheel (31) and a handlebar (22), a seat (41) configured to accommodate a child, a safety element (50) configured to surround at least a first area of the child's body when it is installed on the seat (41), the handlebar (22) being removable between: a first configuration in which the handlebar (22) is remote from the safety element (50), and a second configuration in which the handlebar (22) is close to the safety element (50) and surrounds a second area of the child's body.

A vehicle for an infant having a vehicle body (10) having a front end (11) and a rear end (12), a front steering unit (20) mounted on the front end (11) and including a steering column (21) on which a front wheel (31) and a handlebar (22) are mounted, a seat (41) mounted between the front end (11) and the rear end (12), a first rear wheel (321) connected to the vehicle (10) body via a first wheel carrier (171) and a second rear wheel (322) connected to the vehicle body (10) via a second wheel carrier (172), the first and the second wheel carriers (171, 172) being rotatably mounted on the rear end (12) between a compact configuration and a deployed configuration, the first and the second wheel carriers (171, 172) being movable between the two configurations independently of each other.

A child stroller system can convert from carrying a single child to carrying two children without removing a first child-carrying apparatus from the stroller and without adding adapters to the stroller. Both child-carrying apparatuses can be repositioned with respect to the stroller's chassis when mounted on the stroller. A self-standing and collapsible auxiliary basket can be mounted on the stroller in place of one of the child-carrying apparatuses.

A collapsible or foldable stroller frame is disclosed herein. The stroller frame is configured to be folded into a compact size using a series of connections between a handle portion, front leg portion, and rear leg portion. In one aspect, a basket assembly is also provided that is attached to the stroller frame and is configured to fold into a perimeter defined by the folded stroller frame. In another aspect, an adaptor assembly is provided that allows for a connection or support interface between a carrier and the stroller frame.

A child seat includes a seat portion, a backrest frame pivotally connected with the seat portion, a front guard extending transversally above the seat portion and having a side end portion pivotally connected with the seat portion, the front guard being rotatable relative to the seat portion between an unfolded position and a folded position, and a folding mechanism including a latch connected with the seat portion, the latch being movable relative to the seat portion and the front guard to engage and disengage the side end portion of the front guard, the latch being engaged with the side end portion for locking the front guard in the unfolded position and disengaged from the side end portion for unlocking the front guard.

A motorized riding stroller is provided including a frame having a base platform, a handlebar, and a plurality of legs, wherein the plurality of legs extend from a lower surface of the base platform. The handlebar is pivotally affixed to a rear side of the base platform. An interchangeable seat is removably securable to an upper surface of the base platform. A standing platform is disposed between a pair of rear legs, wherein the pair of rear legs are disposed on opposing lateral sides of the base platform along a rear side thereof. A wheel is affixed to a distal end of each leg of the plurality of legs, wherein each wheel is operably connected to a motor disposed within an interior of the frame. The wheels rotate upon actuation of a drive control disposed on the handlebar, such that the stroller can move in opposing directions.

A seat height adjustment mechanism includes a locking bar and a locking element. The locking bar is disposed in a stroller frame and has locking holes spaced apart. Each of the locking holes has a stop portion protruding therein. The locking element is mounted on a seat and has an engaging end. The engaging end is separably engaged in any one of the locking holes and has an engaging hook protruding in a direction, and the direction is crossed with another direction in which the engaging end moves when the engaging end is separating from the locking hole. The engaging hook separably presses against the stop portion. Therefore, the engaging end cannot separate from the locking hole. Even when wrongly operated, the locking element cannot be rotated and unlocked and thereby prevents the seat from unnecessarily sliding downward, so as to ensure safety of a baby at the seat.
