  • Patent number: 7445231
    Abstract: A handcart with a foldable handle structure comprises a handle structure formed of a holder segment and a frame pivotally coupled to each other. The lower ends of the frame are pivotally coupled to a block board and a pair of wheels. A pair of position-limiting sleeves wraps the tubes of the holder segment. When the handcart is in use, the position-limiting sleeves are pulled down to wrap the pivotal joints between the holder segment and the frame to confine the handle structure to a straight line. Then, the user can hold the handle and push the handcart forward. When not in use, the position-limiting sleeves are pushed up to reveal the pivotal joints between the holder segment and the frame, and the holder segment can thus be folded down. Thereby, the volume of the handcart can be reduced to facilitate storage or convenience lifting the handcart to carry about.

  • Patent number: 7441785
    Abstract: A foldable handcart can be carried about on its wheels after being folded. The handcart has a handle structure. The lower ends of the handle structure are pivotally coupled to a frame. The frame is formed of a pair of tubes. The lower ends of the tubes are pivotally coupled to a block board. The block board can be rotated upward to contact the frame. The lower ends of the tubes are respectively sleeved by a toothed ring which engages with the teeth on the top of a sleeving tube of a wheel seat. The other side of the wheel seat is pivotally coupled to a wheel. When the block board is rotated upward, the back wall of the block board is still apart from the ground by an appropriate distance, and the wheels can thus contact the ground. Thereby, the handcart can be easily carried about on its wheels.
