Abstract
Abstract A vibration damping mount has a frame and at least one and preferably, two parallel guides extending therefrom. A support tube extends in the same direction as the guides, and preferably parallel to it, and carries a platform such as a camera platform, on its upper end. A bracket connects the support tube and guides such that the support tube and attached platform can slide in relation to the guides, while being prevented from moving laterally, in particular prevented from rotating, with respect thereto. Resilient means is connected between the support tube and frame so as to inhibit downward movement of the support tube and attached platform, thereby absorbing vertical vibration. A piston arrangement is also further preferably included for reducing larger vibrations. As well, a telescoping foot shaft arrangement and a pan handle arrangement are further provided.
