  • 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.

  • Publication number: 20070049390
    Abstract: A framework folding mechanism of baby swing includes a front supporting stand, a rear supporting stand, and connecting base-plate. The connecting base-plate being installed at the top ends of both the front supporting stand and the rear supporting stand has a developed positioning recess and a folded positioning recess for positioning. When it comes to developing the framework, the top end of the rear supporting stand is retained at the developed positioning recess through a resilient element. When it comes to folding the framework, all the operator has to do is directly pulling the connecting base-plate to make the top end of the rear supporting stand separate from the developed positioning recess and subsequently rotate to move to the folded positioning recess letting the rear supporting stand approach toward the front supporting stand for folding. In this way, the folding mechanism of the invention is capable of achieving the effect of safety and conveniency.

  • Publication number: 20070010338
    Abstract: A driving mechanism of baby rocking chair includes a transmission system having a transmission motor, a monitoring device, and a control circuit. When the rocking chair oscillates upward and approaches a predetermined set-up high point position that is affected by the gravitational force causing the slowing down of rotating speed, the monitoring device transmits a signal and provides the control circuit with the signal. As the rocking chair reaches the predetermined set-up high point position, the control circuit is capable of switching the direction of the rotation of the transmission motor. It is by this way of controlling the rotating shaft of oscillation of the rocking chair that the control circuit is capable of driving the rocking chair steadily.
