ABSTRACT:
A spring-loaded hoist mountable vertically on a wall is provided for use particularly in mounting a heavy television receiver to a wall and raising it to an elevated position. The hoist includes a fixed housing which is attached permanently to the vertical wall of a room and is formed with a vertical guide channel. A movable carriage is mounted within the housing for vertical reciprocation along the guide channel and is urged upwardly by means of a constant force spring reel assembly mounted in the top of the housing and connected to the carriage. The carriage includes a locking mechanism adapted to engage the housing for locking the carriage in a lowered position and also includes a connecting member adapted to engage a cooperating connecting member of a television by means of which the carriage, when unlocked and supporting a television, may be raised or lowered with little physical effort.
