Description

Description: BACKGROUND OF THE INVENTION (Industrial Application Field) The present invention relates to a massaging machine for applying a desired massage from a shoulder to a neck, and more particularly, to making a head portion provided with a massaging portion movable up and down. In which the pressing force of a roller provided in the rubbing section can be adjusted.

(Prior Art) Conventionally, agitation machines of various structures have been used. For example, some have an arm type structure. In this arm type structure, the arm is attached swingably,
A kneading end is attached to the tip of this arm. Then, the arm is swung to displace the kneading end back and forth, left and right, or in a swirling manner, thereby performing agitation by pressing.

However, in the case of this type of rubbing machine, there is a problem that the operation is monotonous and a desirable rubbing feeling such as hand rubbing cannot be obtained.

Therefore, an abrasion machine using a roller has been considered as one that can obtain a feeling of rubbing closer to hand rubbing. In this technique, desired abrasion is performed by rotating a roller assembly having a plurality of front rollers and rear rollers arranged in a circumferential direction.

(Problems to be Solved by the Invention) According to the above-described conventional configuration, there is a problem that the position of the head to which the roller assembly is attached is fixed in the vertical direction, and the position in the vertical direction cannot be adjusted.

There are individual differences in the position of the shoulder pressed by the roller,
Further, it is preferable that the pressing force by the roller is set slightly higher, but since the position of the head is fixed,
Such position adjustment is impossible, and effective lubrication cannot be performed.

In addition, improvement has been required to provide a feeling of rubbing that is closer to hand rubbing as a whole.

The present invention has been made based on such a point, and an object of the present invention is to make it possible to adjust the vertical position of a head unit having a rubbing unit, and to adjust the pressing force by a roller provided in the rubbing unit. It is an object of the present invention to provide a massaging machine capable of providing a feeling of massaging closer to hand kneading as well as making it possible.

(Means for Solving the Problems) To achieve the above object, a grooming machine according to the present invention comprises a grooming body having a seat portion and a back portion, and a grooming body arranged above the grooming body and moved up and down by means of vertical movement. And a rotating shaft connected to a driving motor provided on the head, and a plurality of front rollers are arranged circumferentially at the front of the rotating shaft. By making the axis of the roller horizontal, the shoulder is pressed vertically from above, and a plurality of rear rollers are circumferentially arranged behind the front roller, and the axes of these rear rollers are set to be horizontal. And an abrasion part which presses the shoulder from behind and obliquely upward by inclining.

In this case, it is conceivable to arrange one of the left and right rubbing units, connect a drive motor to each of the rubbing units, and control the rotation direction and the number of rotations independently.

Further, it is conceivable that a DC brushless motor is used as the drive motor of the rubbing unit.

(Operation) First, the user sits on the main body of the groom and adjusts the vertical position of the head. That is, by moving the head portion up and down, the pressing state of the rubbing portion attached to the head portion against the shoulders of the front roller and the rear roller is adjusted.

At this time, the position of the head portion is set so that the pressing force by the front roller and the rear roller is slightly increased.

After that, the drive motor of the rubbing section may be rotated in that state, and desired shoulder rubbing is performed by the front and rear rollers of the rubbing section.

A variety of lubrication patterns can be provided by arranging the rubbing units one by one on the left and right, connecting the drive motors to each other, and independently controlling the rotation direction and the number of rotations of each rubbing unit.

If a DC brushless motor is used as the drive motor of the rubbing section, it is possible to provide the toughness of torque in a low rotation range. That is, a strong pressing force can be applied in a low rotation state.

Four front rollers 31 are rotatably attached to the front of the rotating shaft 23 via cross brackets 29, 29. These four front rollers 31 are each mounted at a position of 90 °.

Behind the four front rollers 31, four rear rollers 35 are rotatably mounted via cross brackets 33,33. These four rear rollers 35 are arranged at the same position in the circumferential direction as the front rollers 31 and constitute a so-called counter-type.

The front roller 31 is parallel to the axis of the rotating shaft 23, while the rear roller 35 is inclined by α 傾斜. Thus, the rubbing angle A 角度 is constituted by the axis of the front roller 31 and the axis of the rear roller 35. In other words, the shoulder is pressed vertically upward by the front roller 31, and the shoulder is pressed obliquely from the back by the rear roller 35, thereby providing a feeling of massaging close to hand massaging. Things.

Incidentally, the massaging section 21 also has the same configuration as the massaging section 19,
In the drawings, the same portions are denoted by the same reference numerals, and description thereof will be omitted.

The rubbing sections 19 and 21 are configured to rotate independently. That is, the drive motor 37,
39 are arranged side by side in the vertical direction. A pulley 43 is fixed to the drive shaft 41 of the drive motor 37, while
Another pulley 45 is also fixed to the 19 rotation shaft 23. A belt 47 is wound around these pulleys 43 and 45. Therefore, by rotating the drive motor 37 in an appropriate direction,
The rubbing section 19 can be rotated in the same direction.

In addition, a rotation transmitting means having the same configuration is provided between the drive motor 39 and the rotation shaft 23 of the rubbing section 21.
By rotating 39 in an appropriate direction, the rubbing section 21 is rotated in the same direction.

As the drive motors 37 and 39, DC brushless motors are used, which are in a low rotation range and take in the toughness of torque. In addition, the above two drive motors
The rotation speed, rotation direction, and the like of 37 and 39 are controlled by a control device (not shown) in accordance with a preset program.

The parts of the rubbing parts 19 and 21 are covered with a skin material 49. Also, the front roller 31 and the rear roller of the
35 is made of silicone rubber, which gives a comfortable fit.

Next, the structure of the vertical movement means 50 for vertically moving the head unit 3 will be described. As shown in FIGS. 7 and 8, a drive motor 51 is provided on the main body 1 and a gear 54 is fixed to a rotating shaft 53 of the drive motor 51.

On the other hand, below the base 15, a ball screw 55 is extended in the up-down direction, and a gear 57 is fixed to a lower end of the ball screw 55, and the gear 57 is engaged with the gear 54. Therefore, by rotating the drive motor 51 in an appropriate direction, the ball screw 55 can be rotated in an appropriate direction.

A cylindrical body 59 is disposed on the outer periphery of the ball screw 55, and the base 15 and the head 3 described above are fixed to the upper end of the cylindrical body 59. At the lower end of the cylindrical body 59,
The ball nut 61 is installed.
61 is screwed into the ball screw 55.

Therefore, by rotating the drive motor 51 in an appropriate direction, the ball screw 55 is rotated via the gears 54 and 57, and the rotation of the ball screw 55 causes the cylindrical body 59 and thus the base 15 to be rotated via the ball nut 61. The head unit 3 is moved up and down, thereby moving the head unit 3 up and down.

Meanwhile, as shown in FIGS. 1 and 2, an operation panel 63 is attached to the side of the seat 5 of the main body 1 of the rubbing machine. The operation panel 63 has a configuration as shown in FIGS. 9 and 10. In particular, there are roller set buttons 65 and 67. By pressing the roller set button 65, the drive motor 51 is rotated in one direction to raise the head unit 3. By pressing the roller set button 67,
The head motor 3 is lowered by rotating the drive motor 51 in the other direction.

In addition, there are a power button 69, a start button 71, and a stop button 73, and a heating button 75 for turning on / off the heater 13 and buttons 77, 79, 81 for setting the strength of the heater 13.

Reference numeral 83 in FIG. 1 denotes a hand emergency stop switch.

 The operation will be described based on the above configuration.

First, the user sits on the seat 5 and the back 7 of the main body 1. Then, the vertical position of the head unit 3 is adjusted. That is, by appropriately operating the roller set buttons 65 and 67 of the operation panel 63, the head unit 3 is moved up and down, and the rubbing units 19 and 21 are moved.
Adjust the position of the to the shoulder. At this time, the pressing portions 19 and 21 are set so that the pressing force of the front roller 31 and the rear roller 35 of the rubbing portions 19 and 21 is slightly increased.

Next, while operating the power button 69, the start button 71
To start the rubbing operation by the rubbing units 19 and 21. The rubbing operation by the rubbing units 19 and 21 is performed according to a program arbitrarily set in advance. When the desired rubbing operation is completed, the stop button 73 is operated to stop the operation.

In the above rubbing operation, the front rollers 3 of the rubbing units 19 and 21
1. The rear roller 35 is set with a slightly strong pressing force against the shoulder. The drive motors 37 and 39 are rotating at a low speed (for example, 3 to 4 rpm). Accordingly, the shoulder is rubbed with a strong pressing force in a low rotation state.

The front roller 31 presses the shoulder from above vertically, and the rear roller 35 presses the shoulder from behind and obliquely from above. As a result, the shoulder portion sandwiched within the range of the rubbing angle A ゜ is pushed in the vertex direction of the rubbing angle A ゜, which approximates the state of hand massage.

As described above, according to the present embodiment, the following effects can be obtained.

First, in the rubbing parts 19 and 21, the front roller 31 is arranged to press against the shoulder from above vertically,
Further, the rear roller 35 is arranged so as to be pressed rearward from the shoulder and obliquely from above. And since it is made to press directly with the front roller 31 and the rear roller 35 in such an arrangement, it acts just as if the hands were rubbing the shoulder, and it is possible to provide a feeling of rubbing close to hand rubbing. .

Since the head 3 is configured to be vertically movable and the pressing force of the front rollers 31 and the rear rollers 35 of the rubbing sections 19 and 21 can be adjusted, differences in shoulder positions due to individual differences can be absorbed. Then, for example, by setting the pressing force on the shoulder to be strong, it is possible to provide a feeling of kneading closer to hand kneading.

The rubbing parts 19 and 21 are independently driven motors 37 and 39
And independently controllable in any direction at any number of rotations, so that various kneading patterns can be provided.

Since the DC brushless motors are used as the drive motors 37 and 39, it is possible to provide the toughness of the torque in a low rotation range. That is, it is possible to knead with a strong pressing force in a low rotation state, and effective lubrication can be performed.

Since the number of rotations, the direction of rotation, and the like of the massaging sections 19 and 21 are controlled by a program, a desired massage can be reliably applied by creating a program for performing effective massaging.

As the front roller 31 and the rear roller 35 of the rubbing sections 19 and 21,
Since it is made of silicone rubber, it is possible to provide a comfortable fit that is close to hand massage and comfortable.

Note that the present invention is not limited to the one embodiment.

First, the positional relationship between the front roller 31 and the rear roller 35 in the rubbing sections 19 and 21 is not limited to the opposing type, but may be a so-called alternating type shifted by 45 °. That is, the rear roller 35 is arranged to be shifted by 45 ° with respect to the front roller 31. In this case, the pressing by the front roller 31 and the pressing by the rear roller 35 act alternately, and the kneading is performed with twisting added.

Next, the number of rubbing parts is not limited to one on each side, and may be only one, or various configurations such as two on each side may be considered.

The number of front rollers and rear rollers in the rubbing section is not limited to four and may be any number.

As the vertical moving means 50, various types such as a rack and pinion type other than the ball nut / ball screw type are conceivable.

(Effect of the Invention) As described in detail above, according to the rubbing machine according to the present invention, the front roller and the rear roller are arranged in the rubbing section, and the shoulder is vertically moved upward and rearward by the front roller and the rear roller. Since the pressing operation is performed diagonally from above, it is possible to provide an action of kneading by hand, and to provide a feeling of kneading closer to hand kneading.

In addition, since the head to which the rubbing unit is attached can be moved up and down with respect to the body of the rubbing machine, differences in the position of the shoulder due to individual differences can be absorbed. By setting the front roller and the rear roller slightly stronger, it was possible to increase the pressing force and perform more effective lubrication.

In addition, when the rubbing units are arranged one by one on the left and right, and the drive motors are provided independently of each other, the rotation direction and the number of rotations of each rubbing unit can be individually controlled, providing various rubbing patterns. can do.

When a DC brushless motor is used as the drive motor of the rubbing unit, it can provide the tenacity of the torque in the low rotation range, exert a strong pressing force in the low rotation state, and perform effective rubbing. be able to.
