A tiltable tripod stand includes a main post to be selectively tilted and three tripod legs having upper ends which are pivotally connected at the main post. One end of an articular arm is pivotally connected to each leg intermediate its ends and the other end of the arm is pivotally connected to the main post. Two related embodiments for tilting the stand are disclosed. In one, there are two upper holding members on the main post, one movable with respect to the other. One tripod leg is pivotally connected to one upper holding member and another leg is pivotally connected to the other upper holding member so that movement of the one with respect to the other changes the tilt angle of the leg and tilts the main post. In the other embodiment, there are two relatively movable lower holding members. The articular arm from one tripod leg is connected to one lower holding member while the articular arm from another leg is connected to the other lower holding member such that movement of the one lower holding member with respect to the other pivots the respective articular arms which changes the tilt angle of the respective legs which tilts the main post. In one embodiment, the legs are equally spaced around the main post. In another embodiment, the angle between the legs which the main post tilts away from is increased to improve stability. |
