Problems solved by technology

[0009] However, in the electric bed described in Patent Document 1, the back board assembly has the action of gradually leaving the foot board from the horizontal position and moving to the raised position, and the mechanical rotation fulcrum of the back board assembly is below the back board assembly, so , it is difficult to sufficiently eliminate the user's sense of pressure and body sliding when the back is raised, and the link mechanism used to perform the action is complicated
[0010] In addition, in the electric bed described in Patent Document 2, the mechanism for moving the lower end of the frame supporting the back panel assembly along the arc-shaped guide path is also complicated.
Therefore, the number of necessary parts is large, and it is difficult to ensure rigidity by using a link

Embodiment Construction

[0031] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. figure 1 It is a front view showing the electric bed of the first embodiment of the present invention, figure 2 is a diagram showing the rotational fulcrum of its back panel assembly, image 3 is a diagram showing its action, Figure 4 It is a perspective view similarly showing its operation. The trolley frame 1 includes a pair of longitudinal bars extending in the length direction of the bed and at least a pair of cross bars connecting the longitudinal bars. On the pair of longitudinal bars of the trolley frame 1, there are respectively arranged An X-shaped link mechanism in which the first link 3a and the second link 3b are connected therebetween. And the lifting frame 2 is provided on the X-shaped link mechanism. The elevating frame 2 is also the same as the trolley frame 1, and has a pair of longitudinal bars extending in the longitudinal direction of t...

Abstract

Disclosed is an electric bed which is characterized in that have simple structure, and being able to prevent stress feeling on user when lifting back. The bed comprises a back board component (12) in horizontal status, a rotary axle (11) above the back board component (12), when user lying on the bed, the rotary axle (11) is nearer to user's waist than the end part of the back board component (12). When the back board component (12) rotating to the raising direction, the user rotates with his waist as center, the back board component also rotates with the rotary axle (11) as center to reduce user's stress feeling.

Description

technical field [0001] The present invention relates to an electric bed capable of lifting the back by rotating a back board assembly (back bottom), and more particularly relates to an electric bed capable of preventing the body of a person lying on the bed from being pressed or sliding when the back is lifted. Background technique [0002] As a medical bed device, the electric bed can lift or lower the back board assembly through the drive of the actuator to change the position of the paralyzed patient and assist the patient who can move on his own to a certain extent. In addition to not being limited to medical beds, there are electric beds in which the back panel assembly can be lifted and lowered to watch TV or read a book while the bed user remains lying on the bed. [0003] In these electric beds, a back board assembly, a waist board, a knee board, a foot board, etc. are connected, and a mattress is laid on these supports. And, usually, when the back board assembly is...
