In this case, the fifth inclined portion 131e and the fourth inclined from the rotation center point The distance h2 to the uppermost vertex formed between the parts 131d determines the stroke distance of the acupressure unit 50.

In FIG. 5C, the first inclined portion 131a of the cam member 130 is rotated to form a base, and in this case, the fourth inclined portion 131d and the third inclined from the rotation center point The distance h3 to the top vertex formed between the parts 131c determines the stroke distance of the acupressure unit 50.

In this way, the cam member 130 of the present embodiment can adjust the stroke distance of the acupressure unit 50 by varying the distance from the rotation center point to the top vertex according to the rotation angle.

On the other hand, when the cam member 130 is rotated while being positioned under the acupressure unit 50, a large load may be applied to the rotation module 150, so that the linear movement unit 120 It may be set to be rotatable only in a state in which 50 is not provided and is moved forward or backward.

In addition, the shaft member 155 may be formed to vary in height according to the rotation of the cam member 130. This is because the cam member 130 has a polygonal longitudinal cross-sectional shape, and thus the cam member 130 may change in height as a whole when rotating.

In the present embodiment, the rotation module 150 includes an extension part 157 (refer to FIG. 3) provided under the second motor 151 to be elastically formed, and the cam member 130 rotates According to this, the second motor 151 and the shaft member 155 can move up and down together.

In this case, in general use, current is supplied to the coil of the electromagnet so that the attractive force acts on the cam member 130 so that a stable fixed state can be maintained, and when rotation of the cam member 130 is required It is possible to release the attractive force by stopping the supply of current to the coil of the electromagnet.

And, as shown in Figure 6, the acupressure unit 50 is the acupressure unit 52 that is exposed to the upper portion of the ceiling of the housing 10, and through the acupressure unit 52 through the ceiling of the housing 10 An extension part 54 extending into the receiving space S, and a roller part 56 provided at a lower end of the extension part 54 to roll in contact with the cam member 130, A first elastic member 60 formed to surround at least a circumference of the extension 54 at a lower portion of the ceiling of the housing 10 to provide an elastic force in a direction to restore the extension 54 to a lower portion; The housing 10 includes a second elastic member 70 formed to surround at least the circumference of the extension part 54 on the ceiling part of the housing 10 to provide an elastic force in a direction upward of the extension part 54.

That is, the plurality of acupressure units 50 are arranged on the moving path of the cam member 130 provided on both sides of the moving panel 140, and as the moving panel 140 moves back and forth, the cam member ( The acupressure unit 50 in contact with the inclined portions 131a to 131e of 130) moves upward along the inclination of the inclined portions 131a to 131e and then performs a reciprocating movement restored to the lower side. Therefore, the plurality of acupressure units 50 can sequentially reciprocate and pressurize the user's body.

And in this embodiment, the first elastic member 60 is formed in the form of a compression spring to provide an elastic force in the direction of restoring the extension part 54 downward, and the second elastic member 70 also has a compression spring shape. The acupressure unit 50 may protrude slightly to the upper part of the ceiling of the housing 10.

In this case, when the user seats on the upper part of the bed and applies a load, the acupressure unit 50 located in the corresponding area naturally descends, thereby forming a curved surface corresponding to the curvature of the human body.

As described above, the acupressure bed according to the first embodiment of the present invention effectively converts the linear movement of the linear movement unit 120 into the vertical movement of the acupressure unit 50, thereby effectively reducing the driving force generated by the driving unit 160. It is possible to obtain an excellent acupressure effect by transferring it, and the intensity of the massage by the acupressure unit 50 can be adjusted according to the rotation angle of the cam member 130.

8 is a view showing a state of the rotation module 150 in the acupressure bed according to the third embodiment of the present invention.

In the case of the third embodiment of the present invention shown in FIG. 8, it is formed so that the height of the shaft member 155 can be adjusted according to the rotation of the cam member 130 in a different way from the above-described first embodiment.

Specifically, in this embodiment, a slit 152 that is elongated in the vertical direction is formed on the case side of the second motor 151 of the rotation module 150, and the shaft member 155 has such a slit 152. It is formed to be able to move up and down accordingly.

That is, the shaft member 155 is raised together as the height of the rotation center point of the cam member 130 increases while the cam member 130 rotates, and when the rotation of the cam member 130 is completed The cam member 130 may be lowered together by its own weight as the height of the rotation center point of the cam member 130 is lowered.

As described above, the method of adjusting the height of the shaft member 155 according to the rotation of the cam member 130 may be implemented in various ways.
