It is set to be the same as the number of rotations required to wind the rolls to 4, 25. Therefore, from the above, when the moving body 44 travels to the end point position on the pillow base 7 side and the end point position on the base member 8 side, it is reversed and moves in the opposite direction to the moving direction up to that point. Is.

In this case, the mounting plate 64 is fixed so that the switches 65 and 66 are turned on by the actuating member 63 when the moving body 44 travels to the end position near the pillow base 7 and the end position near the base member 8. The position needs to be adjusted. For this adjustment, the hooking hole 67 and the through hole 68 are horizontally long so that the mounting plate 64 can be moved laterally by an amount corresponding to the length of the hooking hole 67 and the through hole 68. An adjusting mechanism 71 for finely adjusting the position of the plate 64 is provided. As shown in FIG. 21, the adjusting mechanism 71 mainly includes an adjusting screw 72, and the adjusting screw 72 is screwed into a nut 73 attached to the casing 17. A groove 72a is formed at the tip of the adjusting screw 72, and a holding piece 64d formed on the mounting plate 64 is formed in the groove 72a.
Are fitted. Therefore, when the adjusting screw 72 is rotated in the forward or reverse direction, the adjusting screw 72 is screwed back and forth with respect to the nut 73,
The mounting plate 64 is moved in the left-right direction by this screwing back and forth.

As will be understood from the above description, the fixed position of the mounting plate 64 is the actuating member 63 when the moving body 44 reaches the end position on the pillow base 7 side and the end position on the base member 8 side. Must be adjusted so that the switches 65 and 66 are turned on. In order to adjust this position, as shown in FIG. 7, the guide rail 1 and the pillow base 7 each have a mark 74 for indicating the end point position.
a and 74b are attached.

The position adjustment of the mounting plate 64 using the marks 74a and 74b is performed as follows. That is, first, the moving body 44 is moved to the end point position on the pillow base 7 side or the end point position on the base member 8 side, and a predetermined portion of the moving body 44, for example, the front end in the moving direction of the moving body 44 is the mark 74a or 74.
Stop at the position matching b. Next, with the mounting screw 69 loosened, the adjusting screw 72 is screwed back and forth to mount the mounting plate 6.
Move 4 left and right. When the moving body 44 is stopped at the end point position on the pillow base 7 side, the switch 65 is moved to a position where it is turned on by the pressing portion 63c of the operating member 63, and stopped at the end point position on the base member 8 side. When the switch 66 is operated, the switch 66 causes the pressing portion 63 of the operating member 63 to
It is moved to a position where c is turned on. Then, the mounting screw 69 is tightened to fix the mounting plate 64 to the casing 17, and the lock nut 75 screwed to the adjusting screw 72 is tightened to fix the adjusting screw 72 so as not to loosen. Since the distance between the two switches 65 and 66 is set in advance to correspond to the distance that the moving body 44 moves between the two end points, one switch is turned on by the actuating member 63 at one end point of the moving body 44. If it is operated, the position of the mounting plate 64 has been adjusted, and the positions of the switches 65 and 66 need not be adjusted again.

As shown in FIGS. 7, 9, 10, and 16, a massage roller 42 is provided between the pair of guide rails 1.
A planar heater 76 is disposed below the planar heater 76, and a support plate 77 is disposed below the planar heater 76. The flat heater 76 is made into a mat-shaped unit by sandwiching a heater wire 80 between a cushion body 78 made of, for example, foam plastic and a cover member 79 made of felt as sheet-like members and adhering the heater wire 80 between them. The member 79 is placed on the support plate 77 with the upper surface thereof. The support plate 77 is made of a hard plastic such as polypropylene and is so-called elastic.

Is pressed from above by a pressing plate 82 fixed to the main plate portion 1b of the guide rail 1. Therefore, the left and right sides of the flat heater 76 and the support plate 77 are sandwiched between the hollow portion 1g of the guide rail 1 and the holding plate 82. Further, the ends of the flat heater 76 and the support plate 77 on the side of the drive device 16 are placed on the base member 8, and the ends on the side of the pillow base 7 are arranged on the pillow base 7 as a support part up and down as shown in FIG. It is inserted and held between the pair of holding pieces 7h. The pressing plate 82 is also configured such that the portion corresponding to the flexible portion 6 of the guide rail 1 has flexibility.

By the way, the heater wire 80 of the flat heater 76
Is a flexible part 6 of the guide rail 1 as shown in FIGS.
Are arranged in a meandering shape except for the intermediate portion corresponding to, and the intermediate portion corresponding to the flexible portion 6 is arranged in a straight line. In this case, on the pillow base 7 side of the plane heater 76, the heater wire 8 is provided in a region within a predetermined distance from the pillow base 7.
0 is not provided, which prevents the user's head placed on the pillow base 7 from being heated.

Further, as shown in FIG. 9, both ends of the heater wire 80 are connected to the lead wire 83 by soldering at the relay terminal block 84. This relay terminal block 84
Is resin-molded including the end portion of the heater wire 80 and the end portion of the lead wire 83, and the waterproof connection structure is formed by this resin molding. Then, as shown in FIG. 23, the female connector 8 connected to the tip portion of the lead wire 83.
5 is a plastic case 8 for housing the control device 70
6 is inserted and connected to a male connector 87, which is a power feeding portion disposed in the inside of the connector 6.

As described above, the guide rail 1 has the flexible portion 6
Can be folded in half and folded in half. A bend detection device 88 is provided to prevent the motor 18 and the heater wire 80 from being energized when the guide rail 1 is bent. As shown in FIGS. 23 to 25, the bending detection device 88 includes a case 86 of the control device 70.
Of a slide member 90 accommodated in a box-shaped guide portion 89 integrally formed on the lower side of the guide rail 1 so as to be slidable in the longitudinal direction of the guide rail 1, and a seat portion 89a formed in the guide portion 89 and a slide member 90. The slide member 90 disposed between
The compression coil spring 91 as an elastic body for urging the slider in the direction of arrow D, which is the direction away from the flexible portion 6, and when the slide member 90 slides in the direction opposite to the arrow D, is pressed by the protrusion 90a of the slide member 90. The switch 92 which is turned on via the leaf spring 92a, and one end of which is connected to the slide member 90 and the other end of which is closer to the pillow base 7 than the flexible portion 6 is a part of the guide rail in this embodiment. It is composed of a wire 94 as a bending detection member made of one metal wire fixed to the holding plate 82 by a screw 93. Here, the connection configuration of the wire 94 to the slide member 90 is as shown in FIG.
4 is bent into an oval loop portion 94b, and a screw 95 passed through the loop portion 94b is screwed to the slide member 90.

The portion of the wire 94 facing the flexible portion 6 is formed as a coil spring portion 94a as a bendable portion that bends when the flexible portion 6 is bent, and the elasticity of the coil spring portion 94a. Due to the flexibility of the wire 94, permanent deformation of the wire 94 is prevented. When the guide rail 1 is extended, the wire 94 is pulled in the direction opposite to the arrow D as shown by the solid line in FIG.
Is moved in the same direction against the elastic force of the compression coil spring 91, and the switch 92 is turned on. On the contrary, when the guide rail 1 is bent by the flexible portion 6, the coil spring portion 94a is bent and the wire 94 is bent as shown by a chain double-dashed line in FIG.
In order to move the whole in the direction of arrow D, the slide member 90
Moves in the direction of arrow D to turn off the switch 92. Then, the control device 70 determines that the guide rail 1 is bent when the switch 92 is off, and prevents the motor 18 and the heater wire 80 from being energized.

A power switch 96 is attached to the rear surface of the casing 17 as shown in FIG. 7, and a power cord 97 and a remote control box 98 connected to the controller 70 are connected to the rear surface of the casing 17. Code 99 has been derived. Then, in the casing 17, as shown in FIGS. 7 to 9 and 23, a cover 100 that covers the casing 17, the first and second drive rollers 22 to 25, the tension mechanism 35, and the like is provided with a screw 101 (see FIG. 20). , FIG. 22).

Here, the control device 70 is configured to include a microcomputer (not shown). The control device 70 energizes the motor 18 when the massage operation is selected by operating the remote control box 98, and energizes the heater wire 80 when the warming operation is selected. When the warming operation is started, the timer function of the microcomputer or a timer provided separately is started to stop the warming operation even if a predetermined time, for example, 8 hours has elapsed from the start of the warming operation. If not, the heater wire 80 is cut off. In this warming operation, the control device 70 controls the on / off of the heater wire 80 based on a detection signal of a temperature sensor (not shown) provided at a predetermined portion of the flat heater 76 to set the flat heater 76 to a predetermined position. Maintain at temperature.

When the massage operation is stopped, the control device 70 keeps the motor 18 energized until the switch 66 for detecting that the moving body 44 has reached the end point position on the base member 8 is turned on. When it is detected that the switch 66 is turned on, the motor 18 is cut off and the massage operation is stopped.

As shown in FIGS. 10 and 16, a pair of prismatic cushion members 102 as holding members are fixed to the outer half of the main plate portion 1b of the guide rail 1. The thickness of the cushion member 102 is set to be considerably thicker than that of the flat heater 76, so that the space between the pair of cushion members 102 is recessed, and when the user lies on the flat heater 76 upward. The body is supported from both sides by the cushion member 102 and held so as not to roll outward.

The main body 103 of the massage device is constituted by the above, and the main body 103 is a bag-shaped cloth inner body 1
04 and the exterior body 105. Of these, the inner body 104 includes a cushion material 106 made of urethane foam or the like except for a portion that covers a region where the massage rollers 42 and 43 move, and the outer body 105 except for the lower half, a cushion material 107 such as cotton. Is included.

Two bands 108 and 109 shown in FIG. 26 are attached to the exterior body 105 by Velcro tape (trade name) 110, and the flexible portion 6 of the guide rail 1 is bent to massage the apparatus. 26 is folded in half as shown in FIG. 26, the tips of the two bands 108 and 109 are bound by the velcro tape 111 so that the massage device can be held in the folded state.

In order to receive a massage by the massage device constructed as described above, the guide rail 1 and thus the massage device are extended as shown in FIG. 8 and placed on the floor.
After the power switch 96 is turned on, the head is placed on the pillow base 7 and the body is laid on the flat heater 76.

After lying on the flat heater 76, the remote control box 98 is operated to start the massage operation. Then, the motor 18 is started, whereby the transmission belt 2 is taken up by the first drive rollers 22 and 23 (rewound from the second drive rollers 24 and 25) or the second drive roller. The moving body 44 reciprocates by being wound around the rollers 24 and 25 (rewound from the first driving rollers 22 and 23). By the reciprocating movement of the moving body 44, the massage rollers 42, 4
3 contacts the back and feet via the inner body 104 and the outer body 105 and moves while rotating, thereby receiving a massage action.

By the way, in order to obtain a good massage action from the massage rollers 42 and 43, the portion to be massaged must be appropriately pressed against the massage rollers 42 and 43. In this case, when a massage is applied to the back, the back may be pressed against the massage rollers 42 and 43 moderately due to the weight of the body, but since the legs are lightweight, the massage rollers 42 and 4 are not pressed.
The pressing force against 3 will be insufficient. However, in this embodiment, since the two outer massage rollers 42 that contact the feet are made hard, a sufficient massage effect can be obtained even if the pressing force is insufficient. Since the massage rollers 42 on the inner side of the back, which come into contact with both sides of the spine in particular, are made soft, a moderate pressing force provides a sufficient massage effect, but the back does not feel rough.

On the other hand, particularly when the temperature is low such as in winter,
If the warming operation is started at the same time as the massage operation is started, the heater wire 80 generates heat to warm the body. At this time,
The heater wire 80 is controlled by the control device 70 so as to maintain a constant temperature and warms the body to an appropriate temperature. However, since the heater wire 80 is not arranged in a region within a predetermined distance from the pillow base 7, the head It is possible to prevent the occurrence of such a problem that the entire portion is heated. The flat heater 7
6, the heater wire 80 is linear in the portion corresponding to the flexible portion 6 of the guide rail 1, so that the heat generation amount is low, but this portion is a portion of the body where the buttocks hit, which is a particular problem. There is no.

Now, massage rollers 42, 4 for a desired time
When the operation of stopping the massage operation is performed after moving 3, the control device 70 turns off the motor 18 when the moving body 44 reaches the end point position on the base member 8 side. When it is desired to take a sleep with the massage device as it is, the heater wire 80 is kept in the energized state during a low temperature such as winter. Then, when waking up, an operation for stopping the warming operation is performed to cut off the heater wire 80. At this time, if the operation of stopping the warming operation is forgotten, the heater wire 80 is maintained in the energized state as it is, but the control device 70 turns on the heater wire 80 when a predetermined time, for example, 8 hours has elapsed from the start of the warming operation. The power is automatically turned off to prevent wasteful power consumption.

As described above, according to this embodiment, the first and second drive pulleys 22 to 25 can be arranged coaxially, so that the first and second drive pulleys have two shafts. In comparison with the case where the two shafts are provided, a mechanism for reversing and transmitting the rotation of the motor to the two shafts is not required, and the structure is simplified.

Further, the rotation transmission from the first driving pulleys 22 and 23 to the second driving pulleys 24 and 25 is transmitted through the groove 27.
a, 29a with connecting holes 27, 29 and ridges 28a, 30a
Since it is configured by fitting with the attached connecting protrusions 28 and 30, the transmission belt 2 can be arranged on the guide rail 1 in a tensioned state without loosening.

By the way, in order to move the pair of supports 46 of the moving body 44 by the pair of transmission belts 2, the pair of supports 46 must be present at the same position. In response to this request, in the present embodiment, the first drive pulley 22 arranged on one end side of the rotary shaft 19 is fitted into the driven gear 21, and the connecting hole 26 thereof is fitted into the driven gear 21 to form the groove 26.

The first drive pulley 23 arranged on the other end side of 9 is configured to be directly attached to the rotary shaft 19,
The rotational position of the first drive pulley 22 on one end side of the rotating shaft 19 (the position of the recesses 22a and 24a) is set to the rotational position of the first drive pulley 23 on the other end side (the position of the recesses 23a and 25a). Since it becomes possible to freely shift it and connect it to the driven gear 21, it is possible to easily adjust the pair of supports 46 to be in the same position by adjusting the rotational position of the first drive pulley 22. It is possible.

Further, in this embodiment, the outer surface 33a of the contact member 33 for fixing the end portion of the transmission belt 2 to the winding peripheral surfaces of the first and second driving belts 22 to 25 is the winding peripheral surface. Since the surface is an arc along the arc, fatigue failure of the transmission belt 2 can be prevented for a long time. That is, when the outer surface of the contact member 33 is a flat surface, when the transmission belt 2 is wound on the winding peripheral surface, the recesses 22a to 25a are wound flat, and the winding belt is arcuately wound. It will start to bend at the boundary with the part that is cut. When it is rewound, its bending is extended, so that it is repeatedly bent and stretched, resulting in early fatigue and fracture. However, in this embodiment, since the outer surface 33a of the contact member 33 is an arcuate surface along the arc of the winding peripheral surface, the transmission belt 2 does not bend and can be prevented from breaking due to fatigue. is there.

Further, in this embodiment, the flanges 22b, 22 are provided on both sides of the first and second drive pulleys 22-25.
Since c, 23b, 23c, 24b, and 25b are present, the transmission belt 2 can be prevented from coming off. By the way, as shown in FIG. 5, when the power transmission belt is wound around the drive pulley, the side edges warp when slidingly contacting the flange, and when the power transmission belt elastically slips off the flange and returns to a flat state, an abnormal noise is generated. Emit. However, in the present embodiment, it is possible to effectively prevent the occurrence of such abnormal noise.

That is, the width M of the winding peripheral surface of each of the first and second drive pulleys 22 to 25 is set to 1.2 times or more the width N of the transmission belt 2. As a result, the transmission belt 2 has the flanges 22b, 22c, 23b, 23c,
It does not come into sliding contact with 24b and 25b. Table 1 below
Is the width M (see FIG. 4) of the winding peripheral surface of the first and second drive pulleys 22 to 25, which is 1 times the width N of the transmission belt 2.
It is set to 1.1 times, 1.2 times, and 1.3 times, and the pitch P between the centers of the first and second driving pulleys 22 to 25 is set to the width N of the transmission belt 2 for each width. 2 times 2.
5 times and 3 times are set, and in each case, the transmission belt 2 has flanges 22b, 22c, 23b, 23c, 24.
The results of experiments on the probability of sliding contact with b and 25b are shown.

Further, Table 2 shows that the width M of the winding peripheral surface of the first and second drive pulleys 22 to 25 is the width N of the transmission belt 2.
1 times, 1.1 times, 1.2 times, 1.3 times, and the first and second drive pulleys 22 to 22 for each width.
The center-to-center pitch P of 25 is 2.2 of the width N of the transmission belt 2.
2 times, 2.5 times, and 3 times, and in each case, how many times the transmission belt 2 is wound, the pitch P between the centers of the adjacent first and second drive pulleys 22 to 25 is set to the flange 2.
2b, 22c, 23b, 23c, 24b, and 25b are the results of an experiment conducted to see if they are in sliding contact.

[Table 2]

As is clear from Tables 1 and 2, the width M of the winding peripheral surface of the first and second drive pulleys 22 to 25 is 1.2 times or more the width N of the transmission belt 2. When set, the transmission belt 2 is set to the flanges 22b, 22c, 2
It is understood that it is effective in reducing the probability of sliding contact with 3b, 23c, 24b, 25b and preventing the generation of abnormal noise. Moreover, the transmission belt 2 has the flanges 22b, 22
Since the probability of sliding contact with c, 23b, 23c, 24b, 25b can be reduced, the transmission belt 2
The lifespan of is also extended.

Table 3 below shows the flanges 22b and 22b.
c, 23b, 23c, 24b, 25b are variously changed, and the transmission belt 2 has the flanges 22b, 22c, 23.
The results of experiments on the probability of generating an abnormal noise when slidingly contacting b, 23c, 24b, 25b are shown. As can be understood from Table 3, the flanges 22b, 22c, 23
According to this embodiment in which the gradient α of b, 23c, 24b and 25b is set to 15 degrees or more, the transmission belt 2 should have the flanges 22b, 22c, 23b, 23c, 24b and 25b.
It is possible to effectively prevent the generation of abnormal noise even when it comes into sliding contact with. Also, the flanges 22b, 22c, 23b, 23c,
Since the inclination α of 24b and 25b is relatively large, that is, 15 degrees or more, the transmission belt 2 has flanges 22b, 22c and 23
Since the degree of warp deformation in the case of sliding contact with b, 23c, 24b, 25b can be reduced, the life is extended.

[Table 3]

On the other hand, the resistance force received by the moving body 44 changes due to the unevenness of the body, and the transmission belt 2 loosens or expands accordingly, so that the moving speed of the moving body 44 tends to change. However, in the present embodiment, since the tension mechanism 35 that applies tension to the transmission belt 2 is provided, the expansion and contraction of the tension mechanism 35 is absorbed to move the moving body 44 at a substantially constant speed to perform a stable massage operation. be able to.

In this case, specifically, the tension of the transmission belt 2 is usually about 7 kg for a person with a weight of about 80 kg, but when the massage rollers 42, 43 massage the concave portion past the hips of the body. As the load is lighter, it drops to about 2 kg. At this time as well, it is necessary that the tension mechanism 35 can apply a tension corresponding to the transmission belt 2. In view of this, in the present embodiment, the tension coil spring 39 is set so as to apply the minimum tension of 2 kg to the transmission belt 2, so that the moving body 44 can be stably operated even under a light load. Moreover, the tension mechanism 35 needs to apply a maximum tension of about 7 kg, but in the present embodiment, the tension coil spring 39 is used.
Since the requirement is dealt with by providing four of them in parallel, the load of each tension coil spring 39 can be reduced, and fatigue failure due to repeated expansion and contraction of the tension coil spring 39 can be prevented for a long time. be able to.
