  • Patent number: 8496417
    Abstract: An adjustable binding belt set includes a binding belt, a fastening component and a handling bar. The handling bar has a spine tube which is passing through an axial rod. A gear on the spine tube is engaged with a switching component. A first spring hole is defined on a handling component. The first spring hole has a spring component placed into and controls the engagement between the gear and the gear tuner. The fastening component includes a fastening base and a fastening slice. The fastening base has an assembling groove defined thereon. The fastening slice is pivoted on the assembling groove. A gear stopper is extruded from the fastening slice and engaged with the gear. The fastening slice further has a resisting part extruded therefrom. Thus, the binding belt is automatically or manually to fasten the goods on a cart when a user operates the handling bar.

  • Patent number: 8474098
    Abstract: An adjustable pulling rod set includes a switch, a base and a cover. The switch is on the base. The switch includes an operating component, two positioning rods and a spring. A rail and two gaps are opened on the operating component. The two gaps communicate with the rail. The two positioning rods pass through the rail respectively. Two abutting nodes are defined on one end of the two positioning rods respectively. Each abutting node has two wings. The two wings abut against the inner side of the two gaps. Both ends of the spring abut against the two abutting nodes of the two positioning rods respectively. When the button is pressed, the two wings are forced by the two slice bodies along the two gaps and the two positioning rods compress the spring. Thus, the height of a pulling rod will be adjustable.

  • Patent number: 8465029
    Abstract: A foldable handcart includes a handle, a cart frame, a carrier board, two wheel seats and two wheels. Two frame seats are deposited on the carrier board for pivoting the carrier board on the cart frame. A front side and a top side are defined on the frame seat. A corner formed by the front side and the top side is a round corner. Therefore when the foldable handcart is not in use, a user presses down the foldable handcart and the wheel seats contact with the corners to rotate the carrier board up slightly according to the lever principle. The user further folds the foldable handcart easily. Furthermore, the carrier board is completely escaping the ground when the foldable handcart is folded.
