ABSTRACT:
A vertically retractable support assembly comprising a plurality of telescoping sets of three or more laterally spaced vertical guide rods, the rods of each set being laterally tied at their lowermost ends to impart lateral stability to the rods thereof. The first set of rods is secured at its upper end to a stationary mount to extend vertically therefrom and support a first carrier for vertical movement on the rods thereof. The second set of rods is secured at its upper end to the first carrier to extend vertically therefrom and support a second carrier for vertical movement on the rods thereof in a telescoping manner relative to the rods of the first set, and so on. A member to be selectively positioned is secured to the lateral tie for the lowermost set of guide rods. Each carrier is urged toward a vertical retracted position by an extendable spring mechanism secured to the mount. A brake normally locks the spring mechanism to hold the carriers in their vertically retracted position. A handle including a brake release is secured to the lowermost lateral tie to permit an operator to simultaneously release the brake and pull down the carriers to an exact stop position controlled by cooperative stops on the carriers and the lateral ties where the brake may be re-engaged to secure the member in the exact stop position.
