Although not shown, the traveling frame 7A on the guide rail 11 side is also connected to the elastic belt 25 passing through the belt guide groove 11B of the guide rail 11 shown in FIG. 8 by a similar structure.

The traveling frame 9A of the pair of left and right movable massage units 9 shown in FIGS. 4 and 5 has the same structure as that of the traveling frame 7A of the movable massage unit 7 described above, and thus the guide frames 10 and 11 shown in FIG. The elastic belts 24 and 25 that pass through the formed belt guide grooves 10D and 11D are respectively connected.

Next, the operation of the massage machine 1 of the present invention configured as described above will be described. As shown in Figure 1,
The user M of the massage machine 1 uses the joints 5A, 5B, 5
C is bent at a desired angle and placed on it, and a remote controller (not shown) or an operation panel provided on the massage machine 1 is operated to drive the motor 13 of the drive unit 12 shown in FIGS. 4 and 5. .

When the motor 13 is activated, the movable massage units 7 and 9 having the massage rollers 6 and 8 are provided.
Is placed in the storage position (standby position), for example, the position shown by the phantom line in FIG.

When the motor 13 starts rotating,
The rotation is performed by the pinion 14 to the pinion 17 shown in FIG.
It is transmitted to the interlocking shaft 16 via and is fixed here.
The reels 18, 19, 20, and 21 start to rotate together with the interlocking shaft 16.

At this time, from the reels 19 and 21 fixed to both ends of the interlocking shaft 16, the elastic belt 24,
25 are extended, and the corresponding guide rails 1
The outer belt guide grooves 10D formed in 0 and 11,
Enter 11D.

On the belt guide grooves 10D and 11D side, the elastic belts 24 and 25 are connected to the left and right traveling frames 9A of the movable massage unit 9, respectively.
Together with the elastic belts 24 and 25, these movable massage units 9 also move along the guide rails 10 and 11.

As shown in FIG. 6, on the head side of the main body frame 2, the belt guide groove 10 of the guide rails 10 and 11 is formed.
The elastic belts 24 and 25 protruding from the ends of D and 11D are
The reversing pulleys 26 and 27 respectively reverse the moving directions and enter the belt guide grooves 10B and 11B.

Since the left and right movable massaging units 7 are connected to the elastic belts 24 and 25 passing through the belt guide grooves 10B and 11B, respectively.
With 25, these movable massage units 9 also move along the guide rails 10 and 11.

On the other hand, the elastic belts 24 and 25 protruding from the end portions of the belt guide grooves 10B and 11B of the guide rails 10 and 11 located on the foot side of the main body frame 2 are the guide pulleys 15 and 22 shown in FIG. 4, respectively. Interlocking axis 16 via
Two reels 18 and 2 fixed to the center of both sides of the
It is wound up to 0.

As described above, when the motor 13 is driven, the movable massage unit 7, which was initially stopped on the head side of the main body frame 2, started moving to the foot side and was simultaneously stopped on the foot side. The movable massage unit 9 starts moving toward the head side.

As the movable massage unit 7 moves, the toothed pulley 3 meshed with the toothed belt 35.
The roller mounting shaft 28 rotates via 6, and with this rotation, the plurality of massage rollers 6 roll around the roller mounting shaft 28 and roll on the back side of the exterior cloth 4 to press the body, Massage.

Similarly, the toothed pulleys 44, which are meshed with the toothed belt 35 and fixed to both ends of the roller mounting shaft 33 on the movable massage unit 9 side, move together with the roller mounting shaft 33 as the movable massage unit 9 moves. Rotate, and with this rotation, a plurality of massage rollers 8
Rolls on the back side of the exterior cloth 4 and massages the body like the massage roller 6.

Thus, when the movable massage unit 7 moves to the vicinity of the waist and the movable massage unit 9 moves to the upper part of the thigh, a limit switch (not shown) is activated to reverse the direction of rotation of the motor 13. ,
Along with this, the moving directions of the movable massage units 7 and 9 are reversed.

When the movable massage units 7 and 9 are returned to the storage position again, the limit switch (not shown) is also activated to reverse the rotation direction of the motor 13 again. Repeats reciprocating motion.

When the operation of stopping the motor 13 is performed from the remote controller or the operation panel provided in the massage machine 1, the motor 13 moves the movable massage units 7 and 9 to the storage position shown by the phantom line in FIG. Stop after returning.

In this embodiment, the limit switch is used to detect the position where the moving directions of the first and second movable massage units 7 and 9 are reversed, and the stop position. These positions may be indirectly detected by detecting the amount of rotation of the interlocking shaft 16 and the like that are present by a rotary encoder or the like.

Further, in the present embodiment, the movable massage unit 7 and the movable massage unit 9 are designed to move in opposite directions, but they are connected in series with the portions of the elastic belt that move in the same direction along the guide rails. The movable massage unit that moves in the range from the neck to the waist and the movable massage unit that moves in the range from the calf to the thigh may move in the same direction.

Further, in this embodiment, the drive unit 12
Are collected at the foot-side end of the main body frame 2, but when both movable massage units are connected in series on the elastic belt as described above, reels are provided at both ends of the guide rail. The movable massaging unit may be moved by feeding out the elastic belt from one of these reels and winding it up on the other reel.
In this case, the reels on both ends of the elastic belt may be connected to the motors, respectively, and the motors may be controlled to rotate synchronously.

Furthermore, the massage machine 1 of this embodiment is
Although it is configured for whole body massage, the present invention is not limited to this, the massage machine is a chair type, the movable massage unit is configured as a massage machine dedicated to the upper body that moves in the range from the neck to the waist. You may.

Further, the massage machine of the present embodiment has a toothed pulley 3 as a driven wheel that is fixed to the roller mounting shaft.
6 and 44, and the toothed belt 35 is used as a driving member, instead of these, a driven wheel body having meshing teeth on the outer periphery is constituted by a sprocket or a pinion, and these meshing members are also used. The drive striation having the meshing portion that meshes with the teeth may be constituted by a roller chain or a rack.

[0078]

As described above, according to the first aspect of the present invention, the reciprocating movement of the movable massage unit along the guide rail is used to rotationally drive the roller mounting shaft to which the massage roller is mounted. Therefore, it is not necessary to mount a drive source for driving the massage roller on the movable massage unit, and the movable massage unit portion can be simplified and reduced in weight.

Further, since the movable massage unit is not equipped with a motor as a rotation driving source for the roller mounting shaft,
Wiring of an electric cable or the like from the main body frame side to the movable massage unit is not required, and as a result, the weight of the entire massage machine can be reduced and the structure can be simplified, and the manufacturing cost can be reduced.

Further, since a plurality of massage rollers revolve around the roller mounting shaft to sequentially roll and press the body surface, an excellent massage effect can be obtained.

According to the second aspect of the present invention, the driven wheel is composed of a toothed pulley and the driving member is composed of a toothed belt in order to rotationally drive the roller mounting shaft. The noise generated when operating the massage machine can be reduced, and the body frame of the massage machine can be configured to be bendable.
