BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a position changing bed having a double locker, and more particularly to a position changing bed having a double locker capable of freely folding or unfolding.

Special beds, especially bed for patients, more particularly severe patients who are forced to live for a long period of time, such as paralytic patients or patients with muscular dystrophy (eg, Lou Gehrig's disease) It is necessary for the patient living only by the patient to change the contact area of the bed periodically to induce ventilation and blood circulation so that a secondary disease such as a pressure ulcer does not occur and to change the body angle even after the meal.

Various kinds of technologies have been proposed for these special beds, but they mainly focus on the lateral folding of the upper body or the knees.

On the other hand, there is a folding bed disclosed in Japanese Patent Application Laid-Open No. 10-2011-0043357 (Apr. 27, 2011) by the present inventor, wherein the upper frame of the foldable bed, So that the lower intermediate frame and the lower frame, which is provided as the hinge portion, can be folded at a predetermined angle through the second bending rod which is connected to the second cylinder So that the frame itself of the bed in which the muscular disease patient is lying can be bent forward and backward at a desired angle to automatically perform up and down movements such as the hips and legs, The third and fourth cylinders and the third and fourth bending rods connected to the left and right sides of the frame, So that the side of the frame of the bed where the muscular patient is lying is bent to the left and right sides by a desired angle to automatically perform the operation of turning the body of the muscular patient to the left and right side, In which the patient is lying on the upper latex mattress of the bed frame provided in the ondol room or the like, so that the patient can easily and easily perform the folding bed automatically through the bed frame.

However, in the further improvement process, the longitudinal folding mode needs to proceed in this state after the lateral folding mode. Therefore, it is necessary to propose a solution to this, and in order to enhance the appearance and lightness and to increase the durability, I proposed the 'Free Roller Bed' (Registration on November 1, 2012).

However, the above-mentioned patent registration No. 1200721 " free-floating bed " includes a safety raising means for safety, and the locking raising means for the longitudinal folding mode is unlocked and structured through the safety raising means, The structure of the locking means is complicated by the means, which leads to an increase in the manufacturing cost and a deterioration of the merchantability.
