摘要： A flag support assembly coupled to a halyard/pulley combination secured to an upper portion of a flagstaff for raising and lowering a flag includes a pivoting member which is free to rotate about the flagstaff so as to maintain the flag downwind relative to the flagstaff and in an unfouled, unfurled condition. With the flag fully raised, the pivoting member extends above the top of the flagstaff and may be rotated by wind direction changes about a vertical axis clear of the flagstaff. With the flagstaff positioned downwind of the halyard/pulley combination, the pivoting member extends over and straddles the flagstaff so as to maintain the flag downwind with respect thereto. The lower end of the flag support assembly is coupled to the halyard by means of an elastic or tension member which permits the tension applied to the support assembly to be varied in a controlled manner. With the flag in the fully raised position, the elastic member is stretched so as to apply increased tension to the support assembly which is then maintained in a generally vertical orientation together with the flag coupled thereto. In order to raise and lower the flag, reduced tension is applied to the support assembly by allowing the elastic member to contract to permit the top-heavy support assembly to assume an inclined orientation wherein it is positioned clear of the flagstaff and may be moved upward or downward on the flagstaff.
