초록 ▼

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.

대표청구항 ▼

A vertically retractable support assembly, comprising: mounting means; a first set of three or more laterally spaced guide rods secured to and extending vertically from the mounting means; first carrier means transverse to the first set of guide rods for vertically receiving the rods thereof to ride vertically thereon; a second set of three or more guide rods secured to and extending vertically from the first carrier means to support and vertically guide a member for selective vertical positioning by the support assembly; extension spring means secured to the mounting means and to the first carrier means for continuously urging the first carrier means upwardly toward a vertically retracted position with the second set of guide rods telescoped within the first set of guide rods; releasable brake means for normally preventing extension and retraction of the spring means; handle means for enabling an operator to exert vertical downward forces on the first carrier means in opposition to the spring means; and operator controllable means for selectively releasing the brake means to permit downward movement of the first and carrier means in response to the downward forces exerted by the operator to selectively and exactly position the member upon release of the operator controllable means whereby the member is held in such exact position by the normal operation of the brake means.
