Abstract
An apparatus for lifting or supporting an item in an elevated condition includes a telescoping post assembly having an inner tube section which provides one end section of the post assembly and an outer tube section which defines an opposite end section of the post assembly. In addition, a gas spring is mounted within the post assembly for acting between the inner and outer tube sections, and a manually-operable lever member is associated with the gas spring and is cooperable with a fulcrum member to effect the movement of the two opposite end sections of the post assembly away from one another so that by positioning the telescoping post assembly between the support surface and the item to be lifted and then moving the actuator mechanism between two conditions effects the lifting of the item from the support surface.
