Flagpole particularly for indicating goals in skiing competitions

Image Number 3 for United States Patent #4161723.

A flagpole, particularly for indicating goals in skiing competitions, comprising an upper flag carrying portion and a lower pointed portion connected by a helical spring. When this flagpole is driven into the ground, it can move elastically laterally when hit by a skier, thus avoiding to be knocked down or causing injuries to the skier. Preferably the flagpole is provided with a semi-cylindrical abutment shell on one side so that it can move only to the other side, with a telescoping sleeve in its lower pointed portion for adjusting its length, and anvils adapted to be struck with a hammer for driving it down into the ground or hard snow.
