Abstract
An improved tripod includes a spike and pad structure for supporting the tripod on the ground. The spike is fixed to the bottom portion of the leg and at an angle with respect thereto and is threaded to receive a spherical ball. Gripping the ball is a pad element, the ball including a groove and the pad including a nubbin received in the groove. Thus, the pad is free to tilt arcuately with respect to the spike and when rotated, the pad also rotates the ball thus allowing the pad to extend beyond the spike or to position the spike within the pad.
