The acupressure device with a dual moving body according to an embodiment of the present invention is an acupressure device with an indirect acupressure method applied, and consists of a double moving body that pushes up the acupressure member (acupressure rod) to simultaneously massage multiple points among the body parts of the user (the person being treated). It is characterized by acupressure that allows for more rapid acupressure treatment.

The acupressure device to which the dual moving body according to this embodiment is applied may be, for example, a spinal acupressure bed 1 as shown in the drawing.

The chiropractic acupressure bed (1), like a general bed, has a bed frame (10) as a basic framework including a top plate that supports the user in a lying state and a support portion that supports the top plate.

Hereinafter, for convenience of understanding and explanation of the invention, the description assumes that the head is forward and the feet are backward, based on the user lying on the spinal acupressure bed (1), and the left and right sides correspond to the left and right sides of the user's body. I decided to do it.

The acupressure unit frame 20 is disposed on the longitudinal center line connecting the front and rear of the bed frame 10. The acupressure unit frame 20 can be placed on one side of the bed frame 10, that is, at a position corresponding to the area where the spinal acupuncture points are located (from the neck to the buttocks) when a user of average height lies down. . In this embodiment, since acupressure is performed while a person is lying on a table, the pressure applied to the body during acupressure is distributed, thereby providing comfort.

A plurality of acupressure rods 22 installed in the acupressure unit frame 20 move up and down to provide acupressure pressure on the user's spinal acupuncture points. To this end, the upper plate of the bed frame 10 may be formed with longitudinal openings that are long forward and backward so as not to interfere with the lifting and lowering movement of the plurality of acupressure rods 22.

On the acupressure unit frame 20, an acupressure unit plate 21 having a plate structure in which a plurality of vertical movement passages are formed along a plurality of rows is disposed. In each row, a predetermined number (for example, two) of the upper and lower east passageways are arranged on the left and right sides. One acupressure rod (22) is fitted and coupled to each of the Shanghai East passages.

A lubricating member may be provided on the lower side of the upper and lower sinus passage where the acupressure rod 22 is inserted to reduce wear and noise caused by friction between the acupressure rod 22 and the upper and lower movement passage. The lubricating member is made of wool material containing lubricating oil and is inserted into the acupressure rod 22 in the form of a ring and can be installed on the acupressure member plate 21 together with the acupressure rod 22.

Referring to Figure 6, the acupressure rod 22 includes an acupressure head 222, a rod body 224, and a coupling member 226.

The acupressure head 222 has a convex surface and can directly and gently apply acupressure to the user's body, especially spinal acupressure points. Protrusions may be formed on the surface of the acupressure head 222 to increase the acupressure effect.

The rod body 224 has a passage formed on the inside, the upper part is fitted with the inner fitting groove 223 of the acupressure head 222, and can be fixed with adhesive.

At the lower part of the rod body 224, a fitting hole 227 into which a connecting shaft 25 for connecting and installing a plurality of acupressure rods 22 is inserted may be screwed to a coupler 226 formed in the horizontal direction. For this purpose, nuts 225 and bolts 228 may be formed on the lower inner surface of the rod body 224 and the upper outer surface of the coupler 226.

Referring to Figure 5, the acupressure head 222 has a larger diameter than the rod body 224. The inner diameter of the Shanghai sinus passage may be smaller than the diameter of the acupressure head 222 and larger than or equal to the diameter of the rod body 224. Accordingly, the acupressure rod 22 has a structure in which the acupressure head 222 is caught on the upper surface of the acupressure member plate 21 when the acupressure rod 22 is fitted into the upper and lower sinusoidal passage. Here, a bushing 23 is installed in the upper and lower passage, so that the rod body 224 can be smoothly raised and lowered.

A spring 24 is interposed between the lower surface of the acupressure plate 21 and the coupler 226, so that the acupressure head 222 maintains the basic posture of being placed on the upper surface of the acupressure plate 21 when there is no external force. can do.

Referring again to FIG. 3, the roller 26 installed at the center of the connecting shaft 25 by the mobile lifting modules (31, 32, hereinafter also referred to as '30') corresponding to the moving object exerts force in the upward direction. When received, the acupressure bar 22 fitted into the connecting shaft 25 also rises upward.

When the mobile lifting module 30 moves forward and backward, the roller 26 is pushed up and down along the inclined surface 33 or 34 formed on the upper part, thereby allowing the acupressure bar 22 to move up and down.

Depending on the embodiment, the connecting shaft 25 and the roller 26 may be omitted, and the acupressure rods 22 may be individually raised and lowered. In this case, each of the acupressure rods 22 may be directly supported by the movable lifting module 30 and may rise by receiving force in an upward direction.

When the force in the upward direction disappears as the mobile lifting module 30 moves, the acupressure rod 22 is lowered by gravity and the spring 24 so that the acupressure head 222 is placed on the upper surface of the acupressure member plate 21. You will return to your default posture.

In this embodiment, a pair of mobile lifting modules 31 and 32 is provided and functions as a double mobile body. A pair of movable lifting modules 31 and 32 are arranged at regular intervals in the front and rear directions and are fastened to the timing belt 42 so that they can move forward and backward along the length of the bed. As the pair of mobile lifting modules 31 and 32 move together, it is possible to simultaneously apply acupressure to the front and back spaced apart body parts of the user in a lying state.

At least one inclined surface (33 or 34) of the pair of mobile lifting modules (31, 32) may have a structure whose inclination angle is variable as needed. In this case, the mobile lifting modules 31 and 32 include a link part of a pentograph structure, and the inclination angle can be changed by adjusting the width of the link part.

In addition, at least one of the pair of movable lifting modules 31 and 32 has an inclined surface coupled to the mobile bogie (310 in FIG. 9) in a hydraulic cylinder-piston structure or a bevel gear or worm gear structure so that the inclined surface is connected to the mobile bogie (310 in FIG. 9). 310), the height may be implemented to be adjustable. In this case, the inclined surfaces of the mobile lifting modules 31 and 32 can produce various acupressure effects by varying the protruding height of the acupressure bar 22 through vertical height adjustment.

A pair of mobile lifting modules 31 and 32 are fastened to the timing belt 42 and can move back and forth along the longitudinal direction of the bed by the operation of the timing belt 42.

It is assumed that the first mobile lifting module 31 is placed at the rear and the second mobile lifting module 32 is placed at the front. One end of the timing belt 42 may be fastened to the rear end of the first movable lifting module 31, and the other end may be fastened to the front end of the second movable lifting module 32. A fixed connection belt 43 may also be fastened between the front end of the first movable lifting module 31 and the rear end of the second movable lifting module 32.

When the timing belt 42 is operated by the drive unit 41, the first movable lifting module 31 and the second movable lifting module 32 can be moved forward (see (a) of FIG. 3) or backward (see FIG. 3 (a)). (see Figure 3(b)).

A plurality of protrusions are formed on the timing belt 42, and a gear having gear teeth that mesh with the protrusions of the timing belt 42 may be installed on the drive shaft of the drive unit 41. Accordingly, the movement length of the timing belt 42 can be adjusted according to the degree of rotation of the drive unit 41, and the forward and backward movement amount of the pair of mobile lifting modules 31 and 32 can be controlled.

In the above, the description focuses on the case where the gap between a pair of mobile lifting modules 31 and 32 is fixed and they move forward and backward as one unit.

Depending on the embodiment, the gap between a pair of movable lifting modules 31 and 32 may be adjusted by a gap adjustment module. Referring to FIG. 7, a first length adjustment bar 61 and a second length adjustment bar 62 may be installed in the middle of the timing belt 42 and the middle of the connecting belt 43, respectively.

By adjusting the length of the first length adjustment bar 61 and the second length adjustment bar 62, the gap between the pair of mobile lifting modules 30 is adjusted to suit the body of the user who is currently receiving the treatment, thereby providing a customized acupressure service. You can maximize the effect of acupressure by providing it.
