  • Hinged flange pole
    Patent number: 5058336
    Abstract: A column is attached at a base flange to a plate of a base member by way of an offset horizontal pivot, and can be pivotally raised and lowered by means of a ram. The pivot lies in the general plane of the flange and the plate so that, when the column is fully lowered, the overall height of the unit in the region of the base member is little more than the length of the flange.
