  • Patent number: 6712206
    Abstract: A golf club-bagging device includes a head frame, a bag and two supporting rods. The head frame includes a board extending from a lower edge thereof, a base formed on the board and two spaced pivotal seats formed on the base. The bag defines a hole. The bag is mounted on the head frame so that the pivotal seats and the base are inserted through the hole. Each of the supporting rods is pivotally connected with one of pivotal seats. The bag includes a thickness equal to that of the base so that the bag is flush with the base when the bag is mounted on the head frame. The base is integrated with the board via injection molding. The head frame pivotal seats are integrated with the base via injection molding.
