ABSTRACT:
A tripod stand for supporting a musical instrument or other object, wherein a main post is provided with an upper slide member to which the upper ends of the three legs of the tripod are hingedly connected. A respective articulated arm connects each leg with the lower portion of the main post. Movement of the slide member up and down causes selective inward and outward movement of the legs. One of the articulated arms is longer than the others and is attached further up its associated leg than the other articulated arms. Consequently, the downward movement of the slide member causes that leg attached to the one arm to move outward further from the main post, making the bottom ends of the legs move from defining an equilateral triangle to defining an isosceles triangle and thereby tilting 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.
