  • Patent number: 8328208
    Abstract: A stroller includes a stroller frame having a pair of lateral members, a footrest disposed rotatably between the lateral members and having a coupling portion, and a locking device disposed between the footrest and the lateral members and operable to allow for an adjustment to an angle of the footrest with respect to the lateral members. The locking device includes an angle-limiting mechanism and an actuator operable to allow the footrest to be pivoted relative to the lateral members to a selected one of a first angular position and a second angular position. The angle-limiting mechanism locks the footrest at the selected one of the first and second angular positions when the actuator is released. When the footrest is disposed at the first angular position, the coupling portion of the footrest is engageable with a retaining member of a car seat.

  • Patent number: 8141943
    Abstract: Children's chair having a height adjusting device and a folding device completes folding up by height adjusting. A first leg frame of the children's chair includes a first upper leg and a first lower leg capable moving relatively. When operating the height adjusting device to adjust the first upper leg relative to the first lower leg, an actuator on the first upper leg pushes a slider of the folding device, which locates at the pivot of the first leg frame and a second leg frame. The slider then interferes with a coupler locating at the second leg frame to disengage from a base mounted on the first leg frame. The second leg frame is then rotatable relative to the first leg frame and may be folded to a folding position. The children's chair is easy to perform height adjustment and folding movement by simply operating a button at the handle.

  • Publication number: 20110304124
    Abstract: The invention relates to a security device for preventing unexpected folding and a child stroller therewith. The security device uses a seat-plate locking part disposed on a seat plate to allow or constrain the folding of a rear leg assembly and a front leg assembly of the child stroller according to whether a child is sitting on the seat plate. When a child is sitting on the seat plate, the folding of the child stroller cannot be performed even though a frame positioning device is unlocked. Therefore, the invention can prevent a child sitting on the seat plate of the child stroller from getting hurt due to an unexpected folding of the child stroller.

  • Publication number: 20110272923
    Abstract: The invention relates to a stroller. A folding mechanism and a foldable stroller with the folding mechanism are disclosed. The folding mechanism includes a pivot device, a first support member, and a second support member. The first support member is pivotally connected to the second support member by the pivot device. The second support member includes a curve portion. There is a gap formed between the first support member and the second support member by the curve portion for preventing fingers from being trapped when the first support member and the second support member pivot close to each other. Thereby, it can prevent fingers from being trapped during folding the foldable stroller, even close to the pivot device.
