Tilting bed esp for medical use has mattress supporting frame moved by drive with motor, reduction gear and arm

摘要

The bed consists of a base frame (112), uprights (114), a mattress supporting frame (115) and a drive mechanism with a motor (118), reduction gear (119), and an output shaft (121) and an arm (122). The upper end of the arm is connected to the output shaft so that it is set vertically when the mattress frame is horizontal, while a guide (124) on the base frame interacts with a roller on the arm's lower end, causing the mattress frame to tilt as the output shaft rotates.
