  • Patent number: 6814368
    Abstract: A foldable stroller has a handle and a primary frame consisting of both a front and a rear member. The handle can be folded to reduce the width of the stroller for storage purposes. When the handle is folded, lateral tubes of the handle are unlocked so that the handle can be moved close to the frame and thereby reduce the height of the stroller. The members of the frame are pivoted on each other so as to reduce the length of the stroller when the stroller is folded. A force exerted on the handle and on the members of the frame can be imparted to each other via an operating rod combination pivoted to the frame so that the pivotally connected parts can be moved close to each other with increased smoothness of the folding process.

  • Patent number: 6767027
    Abstract: A basket support is provided to a foldable stroller. The basket support includes two connecting blocks, two rods, and a pivotal element. The rods are pivoted to respective connecting blocks at outer ends, and the pivotal element at inner ends. The rods are moved closely together with each other when the stroller is folded for storage and transportation. The connecting blocks are detachably fitted to corresponding rear extensions of a seat support. When folded, the basket support together with two rear wheels can support the stroller in an upright folded position. The basket support and the rear wheels are detachable from the frame of the stroller to be placed where spare space results in a packing case for optimal space utility in storage.

  • Patent number: 6761373
    Abstract: A basket support of a foldable stroller includes an U-shaped rod, which has two juxtaposed lateral sections pivoted to respective rear extensions of a seat support of the stroller by use of pivotal blocks. The rod lateral sections and the pivotal blocks are constructed such that the U-shaped rod can only be moved towards, and close to, upper sides of the seat support extensions to a storage position. When the rear wheels of the stroller are detached, and when the stroller is folded to occupy less space in packing, the U-shaped rods are positioned in the folded position to not cause increase of dimensions to the packing case. The lateral sections of the U-shaped rod are substantially parallel with corresponding extensions of the seat support when the stroller is folded, supporting the stroller in upright position together with the rear wheels.

  • Publication number: 20040113394
    Abstract: A supporting mechanism of a foldable stroller includes a connecting member, and a supporting rod. The connecting member is joined to a frame of the stroller, and has a connecting portion sticking out from the frame. The supporting rod is movably passed through the connecting portion of the connecting member, and is pivotally connected to a pivotal portion of the frame at an upper end thereof so that when the stroller is in a folded position, under which the orientation of the pivotal portion relative to other parts of the frame is different from that under a stretched position of the frame, a lower end of the supporting rod can support the stroller in an upright position together with rear wheels of the stroller.

  • Patent number: 6721971
    Abstract: A baby bed has four upper corner elements joined to horizontal and vertical rods. Each upper corner element includes a main body, and an ornamental cover detachably fitted over the main body; the main body has a connecting hole on a bottom extension, and the ornamental cover has a hook for engaging the connecting hole of the main body. Two ends of the main body are formed with narrow slots, and two ends of each horizontal support rods are formed with thin and flat shape; the horizontal support rods are inserted into the slots of the main body at the plate-shaped end portions, and pivotally connected to the main body with pivotal pins. Dimensions of the baby bed can be reduced when it is in a folded position because the slots of the main body occupy relatively little space as compared with a round hole.

  • Patent number: 6721970
    Abstract: A baby bed has feet connected to lower ends of vertical supporting legs. Each of the feet has an upper fixed part, which is joined to corresponding leg when the baby bed is assembled in the factory, and a lower part, which is to be fitted to the upper part later by the user for the baby bed to be used. The upper part has elongated protrusions formed along the bottom, and the lower part has corresponding trenches on the top so that the lower part can be fitted to the upper part with the trenches being mounted onto the protrusions. All of the lower parts of the feet are placed in spare space of a packing box to save space in storage and transportation when the baby bed is folded and put in the box after assembling.
