A hamper of the type having a base with an upper perimetric frame supported on the base, and a sack whose mouth is mounted on the upper frame so that the sack depends therefrom in an extended condition. The lifting apparatus includes a rigid member associated with a lower portion of the sack and extending transversely across the sack. A rope mechanism is coupled to the rigid member and extends upwardly over an edge of the upper frame for raising the rigid member towards the mouth as the cord is pulled over the frame edge. Springs act on the rigid member for upwardly biasing the rigid member towards the mouth. The rigid member can be secured to a lower portion of the sack for raising the lower portion of the sack itself, or it can be provided as a separate platform for insertion within the sack for raising the platform within the sack.
A lifting platform for use in a hamper having a rigid upper frame and a sack, the mouth of the sack mounted on the upper frame whereby the sack depends therefrom, said lifting platform comprising a platform member for insertion within the sack, rope means having one end available for connection at one side of the upper frame, the other end of the rope means available for passing over the edge of an opposing side of said upper frame, and a portion of the rope means intermediate its ends slidably coupled across said platform member, whereby when said other end of the rope means is pulled over the frame edge, said platform member is raised towards said upper frame, and spring means acting on said platform member for upwardly biasing said platform member towards said upper frame.
