  • Patent number: 6682027
    Abstract: A base seat of golf bag is disclosed. It includes a base board, a front flexible stop plate section, a fixed rear jaw section, a front socket, and a rear socket. The base board has a front jaw section that can be slightly up and down biased by an angle. This front flexible stop plate section is disposed between the base board and the front jaw section. The base board of the base seat always keeps entirely contacting with the ground so that the frictional force against the ground is greater and the base seat can be stably placed on the ground. The golf bag with the base seat can be inclined by any arbitrary angle within a range.
