20120217096Stair-avoiding device - With an aging population, stair safety is a growing concern. Many inventions have been suggested to aid older people in handling stairs. Most of them offer sitting arrangements that are moved by rather complex motor-driven devices attached to one side of the stairs. These devices are complicated and expensive. A new device is suggested that consists of a vertical pole turned by a reversible motor, thereby moving the platform up or down. The platform carries standing person(s) one by one, or two or three in a group, or one sitting in wheelchair from one floor to the next above or down below. This device is inexpensive, can be used with stairs interrupted by landings or with spiral staircase, and does not require the changing or redistribution of the designed building spaces.08-30-2012
