AUFSPREIZSICHERUNGSVORRICHTUNG FUER EIN DREIBEINIGES INSTRUMENTENSTATIV

摘要

The legs of a tripod are held in support position against further spreading by a flexible cable that is unspooled from a spring biased drum. The spring bias will respool the cable when the tripod legs are collapsed. The drum is in a housing fixed on one of the tripod legs, and the housing includes a locking device for locking rotation of the drum so as to fix the effective length of the cable and thus hold the legs to the position set by the cable length.
