  • Patent number: 7490848
    Abstract: A mechanism for switching the wheels of baby stroller between a fixed-direction mode and a free steering mode by a far-end controller drives a positioning member through a connecting member. The positioning member is used to catch and fix the wheel seat of the stroller into the fixed-direction mode, and is also capable of releasing the wheel seat back into the freeing steering mode. The far-end controller enables a user to shift the mode of steering without bending down, and eliminates the need to suspend the front wheel while steering the baby stroller, in order to change direction.
