Abstract: A three-dimensional adjustable ceiling suspension for a surgical microscope includes a first platform for holding the surgical microscope and a second platform connected to a ceiling disposed above and in spaced relationship to the first platform. Six extendable connecting elements interconnect the two platforms. Six lower articulating joints connect the connecting elements to the first platform and six upper articulating joints connect the connecting elements to the second platform. The lower articulating joints are disposed on the first platform along an imaginary first circle and the upper articulating joints are disposed on the second platform along an imaginary second circle. A plurality of drive units are connected to corresponding ones of the extendable connecting elements. A computer-supported drive makes it possible to freely select the position of the surgical microscope as well as realize a rotation and inclination about an imaginary fixed point lying in the center of the object field.

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.

Abstract: A pipe hanger in which the height of a suspended pipe can be adjusted comprises a telescoping hanger rod having a first section and a second section which slides within the first section and a means for securing the two sections in a fixed relation to one another. The first section has at least one pair of diametrically opposed holes and the second section has sets of diametrically opposed holes running axially along its length. A pair of manually operable keys is pivotally attached to a ring which fits snugly around the first section. At one end of each key is a locking plunger which, when inserted into aligned holes in the two sections, maintains the two sections in a fixed relationship. The height of a suspended pipe can easily be adjusted by disengaging the plungers from the holes and sliding the second section of hanger rod within the first section until a new set of holes in the second section are aligned with the holes in the first section.
