A tripod comprises a main body with three radially extending arms, and a leg connected to each arm so as to pivot through about 180 degrees with respect to the main body, so as to pivot between a first position wherein the leg is generally parallel to and below the main body, and a second position wherein the leg is generally parallel to and above the main body. Each arm includes at least one projection for releasably fixing the connected leg at a third position between the first and second positions. In one aspect, each leg includes an angle lock for engaging the projection on the arm, the angle lock mounted to a top end of the leg and configured to move in a radial path, relative to the main body, into and out of engagement with the projection. In another aspect, each leg includes an angle lock for engaging the projection on the arm, the angle lock mounted to a top end of the leg and configured to move in an axial path, relative to the leg, into and out of engagement with the projection. In yet another aspect, each leg includes an angle lock for engaging the projection on the arm, the angle lock pivotally mounted to a top end of the leg and configured to pivot into and out of engagement with the projection.
