Claims

[Scope of utility model registration request]

The back floor plate, the lumbar floor plate, and the foot floor plate are connected to each other in a flexible manner, and a fixed support arm protruding from the floor plate support frame is connected to the back floor plate at an appropriate distance away from the connection point with the lumbar floor plate toward the head. The lumbar floorboard and the foot floorboard are movably fixed, and the lumbar floorboard and the foot floorboard are provided with a first rotation support arm connected between the foot floorboard and the floorboard support frame at a position apart from the connection point thereof, and The foot floor plate or waist floor plate is supported at a position close to the connection point by a second rotary support arm connected between the floor plate support frame, and an operating arm is provided below the back floor plate. At the same time, a rod inserted between the tip of the actuating arm and the floor plate support frame is made impossible to extend or contract with respect to the cylinder by the tightening force of a coil spring built into the cylinder, and the tightening force is reduced. A support mechanism for a floorboard in a floorboard undulating type bed, characterized by connecting telescopic rods that can be expanded and contracted by being released.
