초록 ▼

A modular projector lift system for moving a projection device along a path between an extended position and a retracted position. The modular projector lift system includes a drive assembly expandable along a first axis. At least one movable support is mechanically engagable with the drive assembly at a plurality of positions along the first axis. The movable support moves the projection device between the extended position and the retracted position. A brake mechanism is optionally included for retaining the projection device at a particular location. The brake mechanism includes a plurality of rotating brake plates connected to the drive shaft of the drive assembly and a plurality of static brake plates connected to the drive assembly compressively engaged with the rotating brake plates. Adjustable limit switches are optionally provided for adjusting a location of the retracted and the extended positions along the path.
