  • Patent number: 8820775
    Abstract: A folding golf cart composed of a frame, pillar, handle, handle connector secured to the top of the pillar, and a frame connector secured to the rear end of frame. The handle is rotatably connected with the handle connector, the bottom end of the pillar is pivoted to the frame connector and the rear wheel carrier is connected on both sides of the frame connector. A frame lock is connected between the pillar and frame connector, a handle lock is connected between the handle and handle connector. The handle lock is composed of a manipulator rotatably connected with the handle connector and two gear joint sockets connected with the handle. The two gear joint sockets are pivoted respectively on both sides of the handle connector. Clutch gears for engaging with the gear joint socket are arranged between the manipulator and two gear joint sockets.

  • Patent number: 8757645
    Abstract: A height adjustment device, which includes a base, which connects to a main bar of a golf cart, and a sliding block which connects to a handle of the golf cart. There are two parallel arc oriented plates formed on each side of the base, and sliding block on both sides of the location near the opening matching with the corresponding slide guide plate. Movement of the sliding block along the base of the curved guide plate adjusts the angle and position between the sliding block and base. Furthermore, the movement can adjust the angle and position of the handle and the main bar and the overall height of the device. The device is simple, suitable for different groups of people, and may adjust handle height at any time.

  • Publication number: 20110215542
    Abstract: An apparatus comprises a chassis comprising a front portion and a rear portion. A main member is joined to the chassis between the front portion and the rear portion for rotation in a generally vertical plane. A folding member is joined to the rear portion of the chassis for rotation in a generally vertical plane. A handle is joined to a top end of the folding member. A connector member is joined to the bottom end of the handle and joined to the main member. A locking device comprises a first portion and a second portion. The first portion is joined to the connector member. The second portion is joined to the main member where a rotation of the handle in a first direction mates the first portion to the second portion, and a rotation of the handle in a second direction folds the apparatus down to the chassis.

  • Publication number: 20110074134
    Abstract: The utility model involves golf cart technology, particularly related to a folding golf cart, which includes a car chassis, the main bar, push handle, folding bar. The main bar, connector, folding bar, and the car chassis together form a four-bar linkage, the connected action of the four-bar linkage moves other components involved in the action accordingly. During usage, press the button and push the push handle backward/downwards, which drives the main bar and the folding bar forward and closed, and makes the golf cart form into a Z shaped of three-panel folding state. This substantially reduces the size, saves space, and is convenient to store and transport. It is also a simple structure, easy to fold or open, and easy to operate.

  • Publication number: 20110074126
    Abstract: This practical new technology involves a golf cart, golf carts, particularly related to the height adjustment device, which includes the base, which connects to the main bar of the golf cart, and slide block which connects to the handle of the golf cart. There are two parallel arc oriented plate formed on each side of the base, and sliding block on both sides of the location near the opening matching with the corresponding slide guide plate. Movement of the sliding block along the base of the curved guide plate adjusts the angle and position between the sliding block and base. Furthermore, the movement can adjust the angle and position of the handle and the main bar and the overall height of the structure. The utility model is simple, suitable for different groups of people, according to needs and to adjust handle height at anytime; low cost and long life.
