  • Patent number: 6893040
    Abstract: A safety seat anchoring mechanism for a stroller and particularly an anchoring mechanism that has a pair of anchor docks connecting to a frame and having a coupling member formed on each anchor dock. The safety seat has a body pivotally coupling with a handle. The handle may be turned relative to the body with an adjusting apparatus to switch to a carrying position and an anchored position. The lower side of the handle is extended to form an anchor hook that is turnable with the handle. When anchoring the safety seat, move the handle to the carrying position and place the body above the anchor docks. Then turn the handle to a usage position to couple the anchor hook with the coupling member and form a latched condition. The anchor position is also attained by switching the handle position. The invention provides direct and effective movements to achieve safety and to prevent inadvertent misuse.

  • Patent number: 6679779
    Abstract: The structure is designed to allow an infant to ride, sit, or lie reclined on a rocker, and to be rocked back and forth, as well as to enable the changing of the rocker's angle of inclination, or the folding of the structure for storage. In the invention, the structure comprises a frontal support frame, a rear support frame, and an arc-shaped rocking frame. On the frontal support frame there is a movable sliding sleeve to which the rear support frame is connected by a hinge. With the movable sliding sleeve, the relative positions of the frontal support frame and the rear support frame may be changed, so as to adjust the frontal support frame's angle of inclination or to draw the frontal support frame close to the rear support frame for folding to facilitate storage.

  • Publication number: 20030020259
    Abstract: A jogging stroller has a collapsible frame comprising two side rails having rear ends pivotably coupled to handle, two front wheel sub-frames having rear ends pivotably coupled to front ends of side rails and front ends rotatably coupled to a front wheel, two rear wheel sub-frames having front ends pivotably coupled to front ends of side rails and rear ends rotatably coupled to rear wheels, two base rails having front ends pivotably coupled to front wheel sub-frames and rear ends pivotably coupled to handle, and a seat assembly extended upwardly from base rails and including a front seat and a rear seat in a longitudinally aligned relationship to the front seat. In collapsing, front wheel sub-frames and rear wheel sub-frames are pivoted toward side rails, handle is pivoted toward side rails, and base rails are moved to abut on side rails as the pivoting of front wheel sub-frames and handle, resulting in a reduction of storage space.
