  • Hampers with improved lifting apparatus
    Patent number: 4300611
    Abstract: 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.
