BACKGROUND OF THE INVENTION This invention relates to a beauty and health device for removing excess fat from the body.

[0002]

2. Description of the Related Art Various types of beauty and health devices have been developed for removing excess fat from the body. As one of them, for example, a stand-type beauty and health device using a massage belt shown in Japanese Utility Model Publication No. 56-34741 is known.

In this beauty and health device, a belt drive unit is provided on a stand erected on the base unit. The belt drive unit is provided with an intermediate shaft that is driven to rotate, and a pair of belt swing shafts are eccentrically connected to both ends of the intermediate shaft with their phases shifted by 180 degrees. A belt holder is rotatably provided on each belt swing shaft so as to be exposed on both outer surfaces of the belt drive unit. The ends of the massaging belt are connected to the pair of belt holders, respectively.

In the above structure, when the belt swing shaft is eccentrically rotated by rotationally driving the intermediate shaft, the masser is rotated.
Since the connecting ends of the belt are alternately pushed and pulled to perform a reciprocating oscillating motion, the reciprocating oscillating motion allows the user to receive a massage on the body, for example, a torso portion.
Thereby, excess fat can be digested and removed by blood.

By the way, since the beauty and health device having the above structure is of a stand type, it is large and inconvenient to move, and the user is in a standing position when receiving a massage. You may not be able to receive a massage while lying on a cushion body such as a mattress.

Therefore, it is possible to reduce the size of the beauty and health device provided with a massage belt so that the user can carry the massage at any desired position and in various postures. It is considered.

However, simply reducing the size of the above-described conventional beauty and health device is not preferable for safety because the eccentrically rotating belt holder, which is a movable portion, is exposed on both outer surfaces of the belt driving portion. Not only that, when the belt drive unit is largely sunk in the cushion body when it is used on a cushion body such as a sofa or a futon having a large cushioning property, the belt holder comes into contact with the cushion body and smooth rotation is impaired. Or the cushion body may be damaged.

[0008]

As described above, since the conventional beauty and health device is of the stand type, it is difficult for the user to freely select the place of use, and it is not simply downsized. Since the movable part is exposed to the outside, there is a possibility that various problems may occur.

The present invention has been made in view of the above circumstances, and its purpose is to make it compact so that it can be easily carried, and to prevent the movable part for driving the massage belt from being exposed to the outside. To provide a beauty and health device.

[0010]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a case-shaped main body, a drive shaft rotatably supported by the main body, and both ends of the drive shaft. A pair of reciprocating drive mechanisms that convert the rotational movement of the drive shaft into a reciprocating linear movement, a pair of sliders that are reciprocally linearly driven by each reciprocating driving mechanism, the reciprocating driving mechanism and the slider are housed inside, and the main body is housed. A slider case rotatably attached to the slider and having an opening formed in a portion corresponding to the sliding direction of the slider; and a massage belt having both ends connected to the slider. Is characterized by.

When the pair of output shafts 82 and 83 are rotated clockwise by pressing the first operation button 104, the first drive shaft 3, the second drive shaft 51 and the third drive shaft 63 are rotated. Can be made.

When the second operation button 105 is pressed to rotate the pair of output shafts 82, 83 counterclockwise, the rotation of the first output shaft 82 is interrupted by the one-way clutch 88. The drive shaft 3 is not rotated, and the second and third drive shafts 51 and 63 are rotationally driven. That is, it is possible to stop only the reciprocating swing motion of the massage belt 29.

Next, an explanation will be given of a usage form when receiving a massage using the beauty and health device having the above-mentioned configuration.
As shown in FIG. 10A, when the user U sits in a chair and receives a massage on the sole of the foot, the support leg 8 is attached to the main body 1.
Then, the legs are placed on the pair of roller units 53 of the main body 1 while being bent at a predetermined angle. Drive source 81 in that state
When is driven in the counterclockwise direction by the second operation button 105, the second drive shaft 51 and the third drive shaft 63 rotate, so that the roller unit 53 also rotates.

Therefore, the user U can receive the massage on the sole of the foot by the first and second roller bodies 58 and 59 of the roller unit 53. Further, since the movable piece 67 swings when the third drive shaft 63 rotates, if the foot is placed on the second protrusion 74 provided on the movable piece 67, the massager can also be moved. Can be received.

Although not shown, if the user U places the calf portion of the foot on the roller unit 53,
You can receive a massage in that part.

On the other hand, when it is desired to remove the fat around the waist, the user U sitting on the chair, as shown in FIG.
The first protrusion 73 is pressed against the back of the user, and the massage belt 29 is rotated to the abdomen on the front side of the user U. When the drive source 81 is operated by the first operation button 14 in this state, the user U has the first protrusion 73 at the back side portion around the waist.
The front abdomen is massaged by the massage belt 29. The pair of first projections 73 alternately push and strike one end side and the other end side in the width direction of the back of the user U to rock the body of the user U.

That is, the user U can receive a massage on the entire waist while being shaken.
As a result, the blood circulation of the entire waist is promoted and improved, so that the excess fat around the waist can be efficiently digested and removed by blood.

By pushing and hitting the back side of the user U with the first protrusion 73, the fat around the waist can be swayed from the inside to masturbate, and the massage belt 29 allows the abdominal fat to be massaged from the outside. -You can That is, since it is possible to give fat to the waist circumference from the inside and outside, it is possible to effectively digest and remove the excess fat.

FIG. 10C shows a case where the main body 1 is installed on a cushion body K such as a sofa or a mattress, and the user U lies on his back and receives a massage. It is possible to receive massage from both the back side and the front side.

The slider case 11 accommodating the slider 17 can be freely rotated with respect to the main body 1 together with the slider 17 and the first drive shaft 3. By rotating the slider case 11, it is possible to freely change the derivation direction of the massage belt 29 connected to the slider 17. As a result, the user U can change the position of the massage belt 29 to be worn on the body and use it in various forms. For example, the user U can sit on a chair and put his / her both legs on the roller unit 53 to hang the massage belt 29 on the waist.

Furthermore, the slider 17 is a slider case 1.
Since the slider 17 that is housed in the housing 1 and is a movable part is not exposed to the outside, the safety and the appearance can be improved, and when the main body 1 is used on the cushion body K, the main body 1 is Even when the slider 17 sinks in the cushion body K, the smooth movement of the slider 17 is not impaired.

Moreover, since the slider 17 reciprocates linearly, the slider 17 is housed in the slider case 11 and the opening 11b is formed in the slider case 11 in the same direction as the moving direction of the slider 17. Thus, the slider 17 can be projected and retracted through the opening 11b. That is, since the slider 17 is configured to reciprocate linearly, the slider 17 can be housed in the slider case 11.

To explain further, if the massaging belt 29 is reciprocally rocked by eccentrically rotating the slider 17, the slider 17 will move circularly. If the slider 17 that moves circularly is housed in the slider case 11, it is difficult to house the slider 17 in the slider case 11 because the direction in which the slider 17 protrudes and retracts from the slider case 11 is not determined.

However, as described above, when the slider 17 is linearly reciprocated to drive the massage belt 29, the slider 17 is accommodated in the slider case 11 because the movement direction of the slider 17 is constant. However, it can be projected and retracted through the opening 11b.

The present invention is not limited to the above-described one embodiment. For example, the mechanism for linearly moving the slider in a reciprocating manner is not limited to the crank, but may be a cam, for example. Any mechanism capable of converting rotational movement into reciprocating linear movement may be used.

[0063]

As described above, according to the present invention, the first reciprocating drive mechanism is provided at each end of the drive shaft provided in the main body, and the reciprocating drive mechanism causes the pair of sliders to reciprocate linearly. The reciprocating drive mechanism and the slider are housed in a slider case rotatably provided with respect to the main body, and an opening is formed in the slider case in the same direction as the sliding direction of the slider. The massaging belt is connected to the slider in the slider case.

According to this structure, the user can receive the massage with the massage belt without using the stand type as in the conventional case, so that the main body can be miniaturized so as to be convenient to carry. be able to.

Moreover, since the slider and the reciprocating drive mechanism to which the massage belt which is a movable part is connected are housed in the slider case and are not exposed to the outside, not only the appearance and safety are improved, but also the cushion body is improved. When used in, the movement of the slider is not impaired even if the main body is largely sunk in the cushion body.

Further, by rotating the slider case, the direction in which the massage belt is pulled out from the main body can be changed, so that the position at which the massage belt is hung on the user can be changed according to the usage pattern.
