Abstract
An improved power operated vertically adjustable table which has a high degree of stability in any vertical position. The table comprises a lower support cage which rests stationary on the floor and acts as the main support for the table and an upper support cage which slides vertically within the larger lower support cage. A table top is attached to the ceiling of the upper support cage. Each of the cages comprise two round disks which are horizontally positioned, one above the other. The upper disks are inter-connected by a plurality of vertically positioned support rods; and the lower disks are similarly interconnected. When the table is in the lowermost or bottom locked position, the ceiling of the lower support cage is in contact with the ceiling of the upper support cage. When the table is in the uppermost or top locked position, the ceiling of the lower support cage is in contact with the floor of the upper support cage. When the table is between these positions, a plurality of lock sleeves are slipped on to each of the rods forming the upper support cage between the ceiling of the upper and lower support cages.
