Abstract: The flag comprises a plurality of telescopic members. A knob member is connected to a tip of an inner end telescopic member and the knob member has a cross-section substantially equal to an outer base member. The knob is fastened to the base member when the flag is closed. A rod is pivotally connected to a base of the end member for radial movement away and toward the end member, and is connected to a side of a signalling sheet which is connected on its other side to the end member. The rod is biased away from the end member as the end member is extended from a remainder of the telescopic members and the rod returns to the end member as the end member is retracted into the remainder of the telescopic members. The rod holds at least part of the sheet taut when biassed away from the end member. The sheet is kept taut and visible when the telescopic members are extended, and the flag can be used to increase personal visibility, especially for small children crossing streets.
