A plurality of horizontal plates 14 are integrally installed on the horizontal frame 11 and the auxiliary frame 13 . The motor 20 is installed vertically on any one of the horizontal plates 14 and the motor shaft is installed to face downward.

The fixed shaft 30 is installed vertically on the plate 14 located in the central portion, a flange 31 is formed at the lower end, and a plurality of assembly holes are formed in the flange 31 and bolted to the plate 14 . is fixed The fixed shaft 30 forms a step so that the bearing B is fitted and caught.

The rotating shaft 50 is installed on the fixed shaft 30 at a slight inclination from the vertical, and is directly installed on the fixed shaft 30 or a third pulley used as a power transmission device 40 as shown in the drawing. It can be fixedly installed on the upper part of (43).

When directly installed on the rotating shaft 50, a bearing insertion groove 71 is formed at the lower end, and the bearing B is inserted and coupled to the fixed shaft 30 and installed. In this case, the third pulley 43 to be described later is integrated with the fixed shaft 30 by a key.

When the rotating shaft 50 is fixedly installed on the third pulley 43 , a bearing insertion groove 43 ′ penetrating downward into the third pulley 43 is formed so that the bearing B can be mounted, and the third pulley 43 . By inserting the pulley 43 into the fixed shaft 30 , the third pulley 43 is installed to rotate from the fixed shaft 30 . Here, the rotating shaft 50 forms a flange 51 through which a plurality of assembly holes are penetrated at the bottom thereof, and forms an assembly hole corresponding to the assembly hole of the rotation shaft 50 at the upper end of the third pulley 43 so as to be integrated by bolting. do.

The power transmission device 40 transmits the power of the motor 20 installed vertically on one side of the frame 10 to the rotation shaft 50, and a first pulley 41 installed on the motor 20; A second pulley 42 installed to rotate on the plate 14 and formed in two stages with different diameters, a third pulley 43 installed on the rotation shaft 50 , and a first pulley 41 and a second pulley 42 . It consists of a first belt 46 connecting the , and a second belt 47 connecting the second pulley 42 and the third pulley 43 . As described above, the power of the motor 20 is decelerated by the plurality of pulleys 41 , 42 , 43 and the belts 46 and 47 and transmitted to the rotating shaft 50 . Here, the pulleys 41 , 42 , 43 and the belts 46 and 47 of the power transmission device 40 may be replaced by chains, sprockets, or gears.

The oscillation plate 60 is installed horizontally on the upper part of the rotation shaft 50, and has a disk shape and its edges are rounded so that the contact with the mattress 1 is smooth during handling and rotation.

The bearing housing 70 is fixedly installed under the swinging plate 60 and may be integrated by welding or fixedly installed by bolting. The bearing housing 70 forms a circular bearing insertion groove 71 that is opened downward, and the axial direction is formed to be slightly inclined from the vertical, and the inclination is designed at an angle coincident with the inclination of the rotating shaft 50 .

Here, the point where the end of the rotation shaft 50 is close to the third pulley 43 is called point A, and the point where the end of the bearing insertion groove 71 is close to the swing plate 60 is called point B, and the point where the end of the bearing insertion groove 71 is close to the swing plate 60 is called point B, and the bearing insertion groove is called point B. The point at which the end of (71) is far from the swinging plate 60 is called point C.

As the point A of the rotary shaft 50 and the point B of the bearing insertion groove 71 are closer, the tilting plate 60 gradually increases, and as the point A of the rotary shaft 50 and the point C of the bearing insertion groove are closer, the swinging plate 60 is closer. The plate 60 gradually becomes less inclined. As a result, when the point A of the rotary shaft 50 and the point B of the bearing insertion groove 71 are closest, the degree of protrusion of one end of the swing plate 60 is highest, and the point A of the rotary shaft 50 and the bearing insertion groove 71 ) when the point C is the closest, the rocking plate 60 is positioned inside the mattress while being in a horizontal state so that the mattress does not protrude.

Therefore, when the motor 20 is driven, the third pulley 43 and the rotating shaft 50 are rotated by the power transmission device 40 , and the swinging plate 60 is tilted along the inclination direction of the rotating rotating shaft 50 . One end of the oscillation plate 60 protrudes upward as it moves, and the protruding portion moves while drawing a circular trajectory. At this time, since the rocking plate 60 is in contact with the mattress 1, the edge rotates and protrudes without rotation by friction. As a result, the mattress protrudes by the rocking plate 60 protruding in a circular trajectory and massages the body of a person lying down in a circular trajectory.

The effect of the massage device for a mattress that protrudes only when used according to the present invention having such a structure will be described in detail.

First, when not in use, the rocking plate 60 is in a horizontal state and does not protrude to the surface of the mattress 1 . That is, the point A of the rotation shaft 50 is in a state located closest to the point C of the bearing insertion groove 71 . In this state, the mattress on which the rocking plate 60 is located does not protrude, so it is not cut on the body.

In this state, if you want to perform a massage, power is applied to the motor 20 to drive the motor 20 . As the motor 20 rotates, the first pulley 41 rotates, the second pulley 42 connected to the first pulley 41 by the first belt 46 also rotates, and the second belt 47 rotates. The third pulley 43 connected to the second pulley 42 also rotates by the . As the third pulley 43 rotates, the rotation shaft 50 fixed to the third pulley 43 also rotates.

When the rotary shaft 50 rotates, the rocking plate 60 is inclined unless the point A of the rotary shaft 50 and the point C of the bearing insertion groove 71 do not coincide, and the mattress also protrudes by the tilted rocking plate 60 . do. At this time, as the inclined rotation shaft 50 rotates, the edge of the swinging plate 60 protrudes while drawing a circular trajectory, and the mattress 1 also protrudes while drawing a circular trajectory by the protruding swinging plate 60, and the user's massage the body

If you want to end the massage, if you stop driving the motor 20, the oscillation plate 60 is tilted and stopped in a protruding state. When the user presses the most protruding part of the rocking plate 60 in the vertical direction, the rotary shaft 50 rotates and the point A of the rotary shaft 50 and the point C of the bearing insertion groove 71 become closer to each other, and eventually the rocking plate 60 The protruding portion descends and is inserted into the mattress (1). Accordingly, since the mattress 1 also does not protrude and is in a flat state, if you sleep in this state, the rocking plate 60 is not cut on your body, so you can sleep soundly.

Figure 5 is a cross-sectional view showing a massage device according to another embodiment of the present invention, as shown in the figure, the rocking plate 60 is automatically protruded and inserted.

In the bearing housing 70 and the rotating shaft 50, a sensor S for detecting each other is installed, so that when the motor 20 is stopped, the point A of the rotation shaft 50 is the closest to the point C of the bearing insertion groove 71. make it stop That is, when the sensor (S) senses, the point A of the rotation shaft 50 becomes the closest position to the point C of the bearing insertion groove 71 . The rocking plate 60 is horizontally positioned by the sensor (S) and inserted into the mattress (1). As such, when the motor 20 is stopped, the operation of positioning the swinging plate 60 into the mattress 1 is not necessary because the swinging plate 60 is automatically inserted into the mattress 1 while being horizontally positioned. Here, it is noted that any sensor that can match the point A of the rotation shaft 50 with the point C of the bearing insertion groove 71 may be used as the sensor S, such as a magnetic sensor.

6 is an enlarged view of the main part showing the use and non-use state of the massage device according to another embodiment of the present invention.

As shown in the figure, the bearing housing 70 is provided with stopping protrusions 72 on opposite sides opposite to each other, and the rotation shaft 50 or the third pulley 43 has a stopper which is caught by both stopping protrusions 72 ( 52), and a spring 80 is installed between the bearing housing 70 and the third pulley 43.

Since the stopper 52 is located between the two locking projections 72, when the rotation shaft 30 rotates, the stopper 52 is caught by any one of the locking projections and the swinging plate 60 also rotates.

Here, when the stopper 52 is in close contact with the locking protrusion 72 on one side, the pivoting plate 60 is tilted so that the point A of the rotation shaft is closest to the point B of the bearing insertion groove 71 and a part protrudes. , when the stopper 52 is in close contact with the locking protrusion 72 on the other side, the point A of the rotation shaft is closest to the point C of the bearing insertion groove 71, and the swinging plate 60 is horizontal and does not protrude. should be

The spring 80 is a tension spring or a torsion spring is used. When a tension spring is used, it is installed on one side of the rotation shaft 50 in an oblique direction, one end of which is fixed to the bearing housing 70 , and the other end is fixed to the third pulley 43 . When a torsion spring is used, the torsion spring is installed to surround the rotating shaft 50 , and one end thereof is fixed to the bearing housing 70 , and the other end is fixed to the third pulley 43 .

Therefore, when the rotation shaft 50 rotates, the stopper 52 is in close contact with the locking protrusion 72 on one side, so that the swing plate 60 is tilted and tilted at the same time to allow a massage by rotating in a state in which a part protrudes. At this time, the swinging plate 60 rotates along with the rotation shaft 50 because the stopper 52 is caught by the locking jaw 72 .

When the driving of the motor 20 is stopped, the rotating shaft 50 is stopped and the rotating shaft 50 is reversely rotated by the tension spring so that the stopper 52 is in close contact with the locking protrusion 72 on the other side, so that the oscillating plate 60 is in a horizontal state. and is inserted into the mattress (1).

In the case of the torsion spring, the stopper 52 minimizes the impact on the stopping jaw 72 because it suppresses the driving force to rotate momentarily when the motor 20 is driven, thereby preventing the stopper 52 and the stopping jaw 72 from being damaged. do.

And by installing a buffer member on the stopper 52 and the locking jaw 72 to absorb the shock when the stopper 52 collides with the locking jaw 72, the life of the stopper 52 and the locking jaw 72 is extended. make it

7a and 7b are operational state diagrams illustrating a massage device according to another embodiment of the present invention, and as shown in the figure, the rotating plate 60 is rotated while not rotating, and the third pulley 43 is When the power is turned off by the sensors S1 and S2, it stops at the set position.

In more detail, the anti-rotation device 90 is installed between the frame 10 and the bearing housing 70 . The anti-rotation tool 90 includes a fixing base 91 fixed to one end of the frame 10 , and a spring 92 having one end fixed to the holder 91 and the other end fixed to the bearing housing 70 . The rotating plate 60 is not rotated by the fixture 91 and the spring 92, but has a tilted structure.

Meanwhile, a first sensor S1 is installed on the frame 10 and a second sensor S2 is installed on the rotating third pulley 43 , but in the process of rotating the third pulley 43 , the first sensor S1 is installed. The sensor S1 and the second sensor S2 are positioned close to each other and then move away from each other by repeating the process. Here, the frame 10 is provided with an elongated fixture 91 and a first sensor S1 is installed at the end thereof so that the first sensor S1 and the second sensor S2 are located at the rotational position of the third pulley 43. can be placed close to each other. Here, the length of the fixture 91 may be adjusted.

However, when the point A is located on the same line as the point C, the first sensor S1 and the second sensor S2 are brought close to each other. That is, this state is a state in which the rotating plate 60 is positioned inside the mattress 1 in a horizontal state so that the mattress 1 does not protrude. When the third pulley 43 rotates by this structure, the point A draws a circular trajectory and moves back and forth between the points C and B, and the rotating plate 60 is inclined and the edges protrude sequentially and massage is possible. On the other hand, when the power is turned off, the third pulley 43 gradually rotates at a low speed and stops in the process where the first sensor S1 and the second sensor S2 detect the third pulley 43 in a section that is close to each other. will stop At this time, the rotating plate 60 is not inclined in a horizontal state, so the mattress 1 does not protrude. As such, since the rotating plate 60 does not rotate, friction with the mattress 1 does not occur to prevent damage to the mattress 1, and the mattress 1 does not automatically protrude when the power is turned off.
