The tripod stand (10) for supporting a musical instrument has a main post (11) provided with an upper slide member (30) to which the upper ends of the three legs (21, 22, 23) of the tripod are hingedly connected. A respective articulated arm (26, 27, 28) connects each leg with the lower portion of the main post. One of the articulated arms (26) is longer than the others and is attached further up its associated leg (21) than the other articulated arms. Consequently, the downward movement of the slide (30) causes that leg (21) to move outward further from the main post and tilts the main post. Greater stability can be achieved by increasing the angle between the two legs that are opposite the leg having the one longer articulated arm. |
