The substrate is nylon,
It is made of polypropylene or a synthetic resin such as hard urethane, but this base is formed in a fairly long plate shape so that the user can lay down the whole body with a margin, and in addition, it is a plate to have appropriate rigidity. The thickness is also relatively thick. Therefore, the base body has a considerable weight, and the weight of the massage device as a whole is heavy, which is inconvenient to carry.

Further, since the massage device is also cold in winter and the like, when the body is laid down, it feels cold and uncomfortable, and there is a problem that the massage effect is inferior because the cold body is massaged. Moreover, there is no cushioning on the part where the body is laid down, and if you lie down for a long time, your back will hurt. Furthermore, since the massage rollers are all made of soft rubber, it is good to receive a massage on the back, but if the massage is applied to the foot (calf) that has a light weight, the pressing force against the massage rollers may be insufficient. There was also a problem that the massage effect was halved.

The present invention has been made in view of the above circumstances. Therefore, the object of the present invention is to reduce the weight by adopting a so-called frame structure and to receive a massage while warming the body. Another object of the present invention is to provide a massage device which does not cause a problem such as a backache even when lying down for a long time, and can obtain a sufficient massage effect for a calf of a foot.

According to the above means, when the user lies in the moving area of the massage roller and activates the drive device, the transmission member moves the moving body, and the massage roller provided on the moving body is placed on the moving body. Since it comes to move while pressing the calf of the back and feet of the lying user,
This allows you to receive a massage. In such a massage device, the base is configured by holding the pair of guide rails at a predetermined interval by the pillow base and the base member, so that the base has a so-called frame structure and the overall weight can be reduced.

Further, by providing the flat heater, the body of the user is warmed by the flat heater to improve blood circulation, so that the massage effect is further improved. Even if the user lays down for a long time after taking a nap or the like, since the part receiving the body is composed of the flat heater having the sheet-like member made of the cushion material, the back or the like does not hurt.

Of the four massage rollers, the inner two massage rollers mainly massage both sides of the spine, and the outer two massage rollers mainly massage the calf of the foot, but the inner massage roller. Since the roller is soft, there is no risk of back pain, and because the outer massage roller is hard, even a light foot can receive sufficient massage.

When the massage operation is stopped, the controller 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 side 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. 4 and 14, the guide rail 1
A pair of prismatic cushion members 102 as holding members are fixed to the outer half of the main plate portion 1b. 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.

The two bands 108 and 109 shown in FIG. 24 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. 24 is folded in half as shown in FIG. 24, the ends 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. 2 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. At this time, the flat heater 76 bends under the weight of the user, but since the flat heater 76 is sandwiched by the hollow portion 1g of the guide rail 1 and the pressing plate 82 on the left and right sides of the flat heater 76 together with the support plate 77. You can fully receive that weight. Further, the flat heater 76 is the support plate 7
Since it is sandwiched between the pillow base 7 and the pair of sandwiching pieces 7h together with 7, it is not bent downward due to the weight of the shoulder portion.

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, especially 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 base 10
Has a frame structure composed of a pair of guide rails 1, pillow bases 7 and base members 8 arranged on both sides in the longitudinal direction thereof, so that the guide rails, pillow bases, drive devices, Compared to the conventional structure that attaches a moving body, etc., it is lighter overall and convenient to carry.

Since the pair of guide rails 1 and the pillow base 7 are connected by the sliding fitting of the engaging recesses 1e, 1f and the engaging portions 7c, 7d, the assembling work is simplified. Moreover, since the pillow base 7 can be prevented from coming off from the guide rail 1 by hanging the transmission belt 2 around the guide pulley 12 mounted on the pillow base 7, it is possible to prevent the pillow base 7 from coming off from the guide rail 1. I'm done.

Further, since the plane heater 76 is arranged between the pair of guide rails 1 and the body is laid on the plane heater 76, the massage rollers 42 and 43 massage while warming the body and improving blood circulation. Therefore, a good massage effect can be obtained.

The flat heater 76 is the cushion body 7.
8 and the body is softly received by the cushion body 78, so that it is comfortable to sleep. Further, since the heater wire 80 of the plane heater 76 is arranged in a meandering shape, the heater wire 8
The arrangement density of 0 can be increased, and the heat generation amount of the flat heater 76 can be equalized in each part. Moreover, since the upper surface of the flat heater 76 is covered with the covering member 79, the massaging roller 4 is deformed by the hollow shaft 45 being bent by the weight of the user.
It is possible to prevent the heater wire 80 from breaking even when the heaters 2 and 43 rotate while coming into contact with the cover member 79.

Work can be done easily.

Since the guide rail 1 is hollow at the portion supporting the flat heater 76, the heat insulating property is high, so that the heat of the flat heater 76 can be prevented as much as possible from escaping through the guide rail 1 to the outside. . Moreover, since the plurality of ribs 1a are provided inside the hollow of the guide rail 1, the strength is stronger than that of the solid one in which the amount of material used is the same.

Further, since the support plate 77 arranged below the flat heater 76 is hard and has a certain degree of rigidity, it is useful for supporting the body well and maintaining a good sleeping posture. For this reason, there is no possibility that the spine will bend, or any other strange posture, and even if the massage device is placed on the floor without noticing that an accessory is placed on the floor, the flat heater 76 will not It can be locally convex to alleviate the pain caused by hitting the back.

As described above, since it is comfortable to sleep and the flat heater 76 can warm the body, it is possible to sleep after massage. in this case,
When the operation of ending the massage operation is performed, one moving body 44
Automatically moves to the end position on the side of the drive device 16 and stops, so that the moving body 44 does not get in the way. Even if the user forgets to stop the warming operation when he wakes up, the heater wire 80 is automatically cut off after 8 hours have passed since the heater wire 80 was energized, so that useless power consumption can be prevented. In particular, in the case where the massage device is used as a bed instead of the bed and the person sleeps overnight, considering that the sleeping time is about 8 hours, it is convenient because the heater wire 80 is not automatically disconnected during the sleep.

Also, when not in use, the massage device is folded in two by bending it at the flexible portion 6 of the guide rail 1.
At this time, even if the heater wire 80 is energized, the switch 92 is turned on in response to the bending of the flexible portion 6, and the heater wire 80 is cut off based on this, so that the heater wire 80 remains energized. Further, it is possible to prevent the occurrence of the problem that the massage device is folded in two and heat is trapped inside and the temperature becomes high. In this case, the portion of the heater wire 80 corresponding to the flexible portion 6 is not arranged in a meandering shape but is arranged in a straight line, so that when it is bent by the flexible portion 6, it is not twisted and is durable. Sex increases.

Further, the heater wire 80 is connected to the lead wire 83, and the connector 8 provided on the lead wire 83.
Since the configuration is such that the heater wire 80 is connected to the connector 87 of the power feeding unit via 5, the heater wire 80 can be easily connected to the power feeding unit. Moreover, the connection portion between the heater wire 80 and the lead wire 83 has a waterproof connection structure by resin molding, and the connector 85 of the lead wire 83 has the casing 1
Since it is connected to the connector 87 housed in the case 86 inside 7, the connecting portion between the heater wire 80 and the lead wire 83 and the connector 85,
It is possible to prevent the problem that the connection portion of 87 is wet and the insulating property is deteriorated as much as possible.
