Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a roller treatment machine that exerts a pressing force on a pressing roller by the action of the patient's weight.

(Prior Art) The conventional roller therapy machine shown in FIG. 2 has a rail 2 provided below the bed 1. One end of this rail 2 is rotatably attached to a support 3, and the other end is It is placed on the lifting jack 4.
A movable frame 5 is mounted on the rail 2 thus constructed, and chain wheels 6, 7 are provided at both ends of the rail 2. A chain 8 is wound around these chain wheels 6 and 7, and both ends of the chain 8 are connected to the movable frame 5. Further, an interlocking wheel (not shown) is fixed to the shaft of the chain wheel 7, and a chain 10 is wound between this interlocking wheel and a wheel 9 fixed to the output shaft of the moving motor m. Therefore, when the moving motor m is driven, the chain wheel 7 rotates, the chain 8 wound around it runs, and the moving frame 5 moves on the rail 2.

A pair of roller supports 11 and 12 are erected on the moving frame 5 as described above, and a rotating body 1 is provided on each of the roller supports 11 and 12.
3 and 14 are rotatably provided. This rotating body 1
A plurality of pressure rollers 15, 16 are mounted on the rotating bodies 13, 14, and chain wheels 17, 18 are provided on the shafts of the rotating bodies 13, 14.

Further, a roller rotation motor 19 is provided between the roller supports 11 and 12, and this rotation motor 1
Chains 21 and 22 are wound around a chain wheel 20 provided at 9 and the chain wheels 17 and 18. Therefore, by driving the rotation motor 19, the rotation bodies 13 and 14 can be rotated.

If the moving motor m is driven with the patient lying on the bed 1, the moving frame 5 moves and the pressing rollers 15 and 16 provided on the moving frame 5 push the patient's body. The desired treatment can be applied by applying pressure.

The pressing force exerted by the pressing rollers 15 and 16 at this time is determined by the height position of the movable frame 5 with respect to the bed 1, which can be controlled by adjusting the jack 4. That is, when the jack 4 is moved upward, the rail 2 rotates clockwise in the drawing about the support 3, and the movable frame 5 rises, thereby increasing the pressing force by the pressing roller. On the other hand, when the jack 4 is moved downward, the rail 2 rotates counterclockwise in the drawing around the support 3, and the movable frame 5 descends, weakening the pressing force exerted by the pressing roller.

(Problems to be Solved by the Present Invention) As described above, in the conventional roller treatment machine, no matter how the jack 4 is moved up and down, the height position near the support column cannot be changed much. For this reason, the range of adjustment of the pressing force near the support column is extremely narrow. In other words, since the rail 2 is rotated to adjust the overall height position, the movable frame 5 is
There was a problem in that when moving in the direction, the adjustment effect almost disappeared.

Further, with this conventional treatment machine, there was also a problem in that the pressing force of the pressing roller was difficult to act on, for example, the waist that curved upward.

The purpose of this invention is to provide a treatment machine that ensures a wide adjustment range for the pressing force of the pressing roller and that also applies sufficient pressing force to curved areas such as the waist. be.

(Means for solving the problem) This invention includes a bed on which a patient lies, and a movable frame that is located below the bed and is movable back and forth. The present invention is based on a roller treatment machine equipped with a pressure roller on which the body weight of the patient acts.

Based on the premise of the above-mentioned treatment machine, this invention includes an adjustment table that is rotatable to adjust the vertical position on the movable frame, and a rotating body in the center of this adjustment table. This rotary body is characterized in that a plurality of pressure rollers are provided, a seesaw body is provided at both ends to sandwich the rotary body, and pressure rollers are also provided on both sides of this seesaw body.

(Operation of the present invention) Since the present invention is configured as described above, by rotating the adjustment table provided with the movable frame, the height position of the pressing roller provided on the adjustment table can be adjusted. In this way, the height position of the adjustment table of the moving frame is adjusted, and no matter where the moving frame is on the rail, it is possible to obtain a pressing force according to the height position of the adjustment table. can.

In addition, since the pressure roller is provided on the seesaw body, for example, even if the pressure roller provided on one side of the seesaw body is located at a curved area such as the waist, the pressure roller provided on the other side of the seesaw body can be If the roller is located on the buttocks, the pressure roller located on the buttocks will be pushed down, and the pressure roller located on the waist side will be pushed up accordingly.

(Effects of the present invention) According to the roller treatment machine of this invention, since the height of the adjustment table placed on the movable frame is adjusted, the above-mentioned adjustment width is adjusted according to the pressing force, regardless of the moving position of the movable frame. It directly affects the force of action. Therefore, it is the same as if the adjustment range was substantially expanded.

In addition, since the pressure rollers are provided on both sides of the seesaw body, even if one pressure roller is located at a curved part such as the waist, if the other pressure roller is located at a protruding part such as the buttocks, the above-mentioned one The curved waist can be pressed by the pressing roller.

(Embodiment of this invention) The embodiment of this invention shown in FIG.
The wheels 25 of the moving frame 24 are mounted on the frame 3. The moving frame 24 configured in this manner is configured to reciprocate on the rail 23 by driving the moving motor m as in the conventional case.

The movable frame 24 is provided with support walls 26 and 27 that stand up on both its front and rear sides, and an adjustment table 28 is rotatably attached to one of the support walls 26. Moreover, on the other support wall 27 side,
Screw shaft 29 passing through adjustment table 28
In addition to providing this screw shaft 29
is the height adjustment motor 3 provided on the support wall 27.
It is linked to 0.

Therefore, when the height adjustment motor 30 is driven to rotate the screw shaft 29, the adjustment table 28 is rotated about one of the support walls 26 as a fulcrum.

A roller support 31 is provided at the center of the adjustment table 28 as described above, and a rotating body 32 and a seesaw body 33 are rotatably provided on the roller support 31. The rotating body 32 has a plurality of protruding pieces 32a formed in a radial manner, and a pressing roller 34 is provided at the tip of each of these protruding pieces 32a. The rotary body 32 configured in this manner is linked to a rotation motor 35 mounted on the adjustment table 28, and the rotary body 32 can be rotated by driving the motor 35.

Further, the seesaw body 33 is connected to the roller support body 31.
The rollers 36 and 37 are provided at both ends thereof so as to be swingable.

When the moving motor m is driven, the moving frame 24 moves accordingly, but at this time, the pressing rollers 36 and 37 provided on the seesaw body 33 are
Move according to the patient's body shape. For example, when one pressure roller 36 is located under the back of the patient lying on the bed 1, the other pressure roller 37 is located on the back side of the thigh as shown. Since the back part is quite heavy, the seesaw body 33 rotates counterclockwise in the drawing to lift the other pressing roller 37 and increase its pressing force. Therefore, even if one of the pressure rollers 36 or 37 is located on a curved part of the body, if the other pressure roller is located on a protruding part of the body, Since one of the pressing rollers is forcibly pushed up, the pressing force of the one pressing roller becomes stronger.

Further, since the adjustment table 28 provided on the moving frame 24 is rotatable to adjust its height, the heights of the pressing rollers 34, 36, 37 are adjusted regardless of the moving position of the moving frame 24. , the pressing force will be directly adjusted.
