  • Patent number: 5135107
    Abstract: A golf bag contains a plurality of parallel vertical tubes fixedly arranged therein, each of which accommodates the shaft of one of the clubs comprising the set of clubs to be retained in the bag. A tube header retains the top ends of a number of the tubes at one height and the remainder of the tubes at another height. The tubes and header are arranged such that a number of the tubes are centered euqidistantly on a circle within the outer periphery of the tube header, with the remaining tubes positioned inside that circle. Each of the tubes designated for receiving a particular iron club includes an outward facing notch therein that extends downward into an adjacent portion of the tube header to retain the heads of the respective iron clubs in an outwardly directed, fixed position. Each of the notches is shaped in correspondence with the shape of the head of the specific iron club which it is intended to receive.
