Abstract:
1. A device to allow suspension of a load and selective lowering of the load from an elevated structure comprising: i. a housing having an upper end with a connection adapted for suspension from an elevated structure and an opposite lower end; ii. a rotatable spool within the housing; iii. a biasing member operably connected to the spool and providing a limited force to urge the spool to rotate in a first direction; iv. a cord connected to and windable on rotation of the spool in the first direction, the cord being unwindable from the lower end of the housing upon rotation of the spool in a second direction, the cord having an unwound length that is substantially longer than the diameter of the spool; v. a base attached to the distal end of the cord, the base being selectively moveable between abutment with the lower end of the housing and a remote position away from the housing associated with the length of the cord, the base including a connection adapted to suspend a load; and vi. a cinching member positioned away from and below the spool in the housing and translatable between a first position and a cinching position providing clamping action of the cord against a clamping surface of the housing to deter movement of the cord relative to the housing to set the length of unwound cord relative to the housing.
