Abstract
An attic lift system is provided, comprising a loading platform attached to a lifting frame having a plurality of vertical frame members, wherein the lifting frame includes a closure member positioned below the loading platform. The closure member includes a plurality of telescopic guide members, wherein the support frame is positioned on an attic floor above an opening in the attic floor. A plurality of support rods extend from the closure member and are threadably engaged with the vertical frame members of the lifting frame. A drive assembly is positioned on the support frame and connected to the lifting frame for raising and lowering the loading platform relative to the opening. Limit switches are present to detect when the drive assembly should be stopped based on the position of the lift platform.

An attic lift system for lifting and lowering a loading platform between a room having a room floor and a ceiling to an attic having an attic floor, comprising:
- a loading platform attached to a lifting frame having a plurality of vertical frame members, wherein the lifting frame includes a closure member positioned below the loading platform and separated from the loading platform by a fixed distance, wherein the fixed distance is approximately equal to the difference in height between the ceiling of the room and the attic floor;
- and wherein the loading platform includes openings for loading and unloading from all sides of the loading platform;
- a plurality of telescopic guide members connected to the closure member and a support frame, wherein the support frame includes openings for loading and unloading from all sides of the support frame, and wherein the support frame is fixed to the attic floor above an opening in the attic floor;
- a plurality of support rods extending from the closure member and threadably engaged with the vertical frame members of the lifting frame, wherein the fixed distance between the loading platform and the closure member can be adjusted to approximate the difference in height between the ceiling of the room and the attic floor;
- a drive assembly positioned on the support frame and operatively connected to the lifting frame for raising and lowering the loading platform relative to the opening;
- and
- a first limit switch operatively positioned on the closure member and in electrical communication with the drive assembly, for detecting when the closure member is adjacent to the room floor, and causing the drive assembly to stop lowering the loading platform.
