A therapeutic bed 1 comprises a patient support platform 2 rotatably mounted on a base frame 5. A pair of side members 30 extend longitudinally of the patient support platform 2 and are mounted for pivotal movement about a longitudinal pivot axis from a raised operative position supporting a patient to a lowered in-operative position. Each side member 30 is carried on a pair of spaced-apart cranked support arms 34, 35 which are bridged by a bridging bar 42 to form a frame. A primary retaining means for retaining the side support in the raised position is provided by a cross bar 65 of the patient support platform 2 on which the bridging bar 42 rests. Each support arm 34, 35 is pivotally mounted to a pivot support sleeve 45 which is slidably mounted on a round bar 46 forming a track. Secondary retaining means is provided by a stop disc 48 having a slot 50 which is moved into and out of alignment with a latch 47 to control movement of the sleeve 45 on the bar 46. An adjustable backrest 80 and a headrest 94 are also provided. |
