摘要： 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.

摘要： A motorized stroller assembly includes a carriage frame. A plurality of wheels is rotatably attached to the carriage and a child seat is positioned in the carriage frame. An electric motor is mechanically coupled to at least a first wheel of the plurality of wheels. The motor selectively rotates the first wheel to drive the carriage frame forward. A battery is mounted on the carriage frame and is electrically coupled to the motor. A control is mounted on the carriage frame and is electrically coupled to the motor and is actuated to drive the first wheel in the first direction. A platform is attached to a rear side of the carriage and extends rearwardly therefrom. The platform is positioned near a bottom of the carriage. The platform supports a person standing on the platform. A canopy is pivotally coupled to the carriage frame and is extendable over the child seat.

摘要： Maneuverable strollers are disclosed. An example stroller includes a frame that includes an upper frame support, an intermediate frame support, a lower frame support, and a handle coupled to the upper frame support. The example stroller also includes a front wheel coupled to the lower frame support, an intermediate wheel having an axis of rotation, and a rear wheel. The intermediate wheel is located between the front wheel and the rear wheel. The intermediate wheel and the rear wheel are coupled to upper frame support via the intermediate frame support. The example stroller also includes a pivot axis, where the intermediate frame support is coupled to the upper frame support about the pivot axis, and the pivot axis is offset above and forward to the axis of rotation.
