  • Patent number: 5779042
    Abstract: A golf bag having a flap for protecting the golf clubs therein from rain. The flap is designed such that it will not be an obstacle when clubs are inserted into or taken out of the bag when it is not raining. The golf bag has a cylindrical body having a top opening covered by a flap. The flap is inclined relative to the axis of the cylindrical body. The interior of the body is partitioned into three spaces by two sheets. Each of putters and irons are placed in one of the spaces of the smallest and medium depths whose depth is nearer to the length of each of the putters and irons so that the putters and irons will not bounce in the bag. The flap is formed with holes right over the third space. A resin pipe is fitted in each hole through which the shaft of a wood can pass. A wood head cover is secured to the protruding end of each resin pipe.
