In addition, a third hinge portion 455 is provided at the other end of the thigh plate 400, the calf plate 600 is hinged to the third hinge portion 455, and the length of the thigh plate 400 is provided. For adjustment, the thigh plate 400 is composed of two separate plates of the rotating plate 410 and the sliding plate 450, and the rotating plate 410 includes a rotating plate protruding arm similar to the back plate protruding arm 210. 415) is provided so that the rod of the second cylinder actuator 510 is rotationally coupled.

However, the conventional frame does not have a separate device for supporting the head, which makes it uncomfortable when adjusting the angle.

Particularly, in a conventional electric bed, when an actuator such as at least one motor or the like is configured, and when the frame is folded by the power provided by the actuator, noise is generated due to various factors such as structural defects and coupling errors of the frame. There is a problem.

Such, it is difficult to provide comfort through the electric bed by making the patient uncomfortable due to noise generation, and there is a problem in that it leaves a bad impression on the product.

Of course, the present invention is not limited thereto, and any structure or configuration capable of preventing noise in an operating state at a link-coupled portion between components may be used.

Looking at the operating state of the frame for the motion bed is configured as described above with reference to Figure 9 is as follows.

First, the motion bed frame of the present invention uses three actuators to provide each of the upper and lower body parts of the body in a 5-section link method to achieve a desired slope, thereby providing comfort and comfort.

<Upper body>

Looking at the operating state for the upper body portion, as shown in Figure 9a, while maintaining the initial flat state, as shown in Figure 9b, the upper body part 20 through the upper body actuator 230 configured on one side of the moving frame 140 Let's look at the state in which the first upper body 210 is set at an angle.

When the reciprocating transfer force, for example, forward force, is provided from the upper body actuator 230, forward force is provided to the upper body rotation bracket 218 coupled to one end of the upper body actuator 230, and thereby, the upper body rotation bracket ( The forward force is transmitted to the first connector 214 to which one end of 218 is coupled.

Accordingly, when the forward force is transmitted to the first connection pipe 214, as the first connection pipe 214 is transmitted to the fixed second support member 212, the second support member 212 is A certain angle is erected around the link coupling between the first link hole 211 of the second support member 212 and the upper body link bracket 1446 of the upper body support tube 144.

Here, the advancement of the first upper body 210 means a direction in which the first upper body 210 is transferred in a direction in which a user's head is positioned in a bed, and the transfer of the moving frame 140 As the erecting angle of the first upper body 210 is associated with the operation, the user's head is supported and the convenience of use by the naturalness as if standing up the upper body is improved.

<Head>

The operating state for the head is made by adjusting the rotation angle of the second upper body 220 linked to one end of the first upper body 210, as shown in FIG. 9C.

That is, when power is supplied from the head actuator 240 fixed to the head bracket 219 of the first upper body 210, power is transmitted to the second head bracket 226 connected to one side of the head actuator 240. In this way, the third support member 222 by the power transmitted to the second head bracket 226, the first link hole 211 at one end of the second support member 212 of the first upper body 210. As a reference, the second upper body 220, that is, the angle that supports the head is adjusted as the angle is rotated at a predetermined angle.

It is transmitted to the bracket 416, and accordingly, the lower pivot bracket 416 is transmitted to the fourth support member 412 through the fixed second connector 414, and one end of the fourth support member 414 As the second link hole 411 and the lower link bracket 1466 of the moving frame 140 are linked, the first lower body 410 rotates at a certain angle based on the second link hole 411. do.

On the other hand, since the second lower body 420 is linked to one end of the first lower body 410, the second lower body 420 is lifted together according to the rotation angle of the first lower body 410.

At this time, the second lower body 420 has a second rotation link 440 between the fifth support member 422 of the second lower body 420 and the first support member 142 of the moving frame 140. By maintaining the link-coupled state, the rotation angle of the second lower body 420 is intermittent according to the rotation radius of the second rotation link 440.

Therefore, the lower body portion 40, the first lower body 410 is rotated at a predetermined angle to the lower body actuator 430 and at the same time, the second lower body 410 to the second lower body according to the rotational radius of the second rotating link 440 420 is rotated at an angle due to the associated operation.
