  • Patent number: 7290786
    Abstract: A placement rack on baby cart, particularly for supporting a movable placement basket having a fastener member; installed on the baby cart frame is a fastener unit that can be engaged with the fastener member, so that they work together to support the placement basket. When placing a larger object, the user can pull on the placement basket support to disengage the fastener member from the fastener unit, so that the placement basket support can rotate downwards to increase the space to accommodate incoming articles.

  • 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.
