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 vertically movable. Thus, the present invention relates to an apparatus that enables adjustment of the pressing force of a roller provided in the rubbing section and also has traction means.

(Prior Art) Conventionally, agitation machines of various structures have been used. For example, some have an arm type structure. In the arm type structure, the arm is swingably attached, and a kneading end is attached to the tip of the 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.

Further, the conventional rubbing machine usually does not have a pulling means for pulling the neck, and a dedicated traction treatment tool is separately used for pulling the neck.

(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.

In addition, for towing the neck, a separate dedicated traction treatment tool is required, and the treatment must be moved to the traction treatment tool, which complicates the treatment. In addition, a general combination of shoulder rubbing and neck traction is required. However, there is a problem that it is not possible to effectively administer a proper treatment.

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. By providing a feeling of rubbing that is closer to hand rubbing overall, and by combining the traction means that pulls the neck, it is possible to eliminate the complexity of treatment and provide a more comprehensive treatment. To provide a massaging machine.

(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. A traction unit including a rubbing unit that presses the shoulder from behind and obliquely upward by inclining, a traction drive unit provided from the rubbing machine main body to the head unit, and a traction tool that is suspended from the head unit. Means and It is characterized by having been prepared.

(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.

Simultaneously with the rubbing of the shoulder portion or when the rubbing of the shoulder portion is completed and the shoulder portion is sufficiently loosened, the neck portion is pulled by the pulling means. That is, the rubbing machine of the present invention can perform not only the rubbing of the shoulder but also the traction treatment of the neck.

It should be noted that the procedure for performing the shoulder rubbing and the neck traction is arbitrary.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 11. FIG. 1 is a front view showing the internal structure of the rubbing machine according to the present embodiment, and FIG. 2 is a side view of the same.

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.

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.

By the way, the rubbing machine according to the present embodiment is also provided with a pulling means 63 for pulling the neck. The traction means 63 has a configuration as shown in FIG. First, there is an electromagnetic clutch 65, which winds the wire 67 by a conston spring winding method, and locks the wire 67 during towing.

The wire 67 is extended through rotating bodies 69, 71, 73, 75, 77, 79, and at the tip thereof, a traction tool 81 is attached, and the lock by the electromagnetic clutch 65 is released. If so, they are free to withdraw.

A load cell 83 is connected to the rotating body 71,
Further, a towing drive motor 87 is connected via a connecting member 85. The signal from the load cell 83 is input to the control circuit 89, and the control circuit 89 controls the traction drive motor 87 based on the signal.

When the neck is towed, the wire 67 is locked by the electromagnetic clutch 65. In this state, the vehicle is towed by the towing drive motor 87 via the connecting device 85 and the load cell 83. At that time, the traction force of the traction drive motor 87 is
Is controlled by the control circuit 89 based on the signal from

The upper and lower limits of the traction force of the traction drive motor 87 are controlled within a certain range by limit switches 91 and 93. For example, when the action piece 94 provided on the connecting tool 85 operates the limit switch 93, the towing drive motor
87 stops, thereby preventing the action of more than a certain amount of traction.

Further, a physical safety device (not shown) is provided so that even if the limit switches 91 and 93 fail, a traction force exceeding a certain level does not act.

The towing drive motor 87, the connecting device 85, the load cell
As shown in FIGS. 1 and 2, the limit switches 91, 93, etc. are provided at the bottom of the main body 1 of the rubbing machine. I have. Further, the towing tool 81 is suspended from the upper end of the head 3.

As shown in FIGS. 1 and 2, an operation panel 95 is attached to the side of the seat 5 of the main body 1 of the rubbing machine. The operation panel 95 has a configuration as shown in FIG. 10 and FIG. In particular, there are roller set buttons 97, 99, and by pressing the roller set button 97, the drive motor 51
Is rotated in one direction to raise the head 3. By pressing the roller set button 99, the drive motor
The head 51 is lowered by rotating the head 51 in the other direction.

In addition, there are a power button 101, a start button 103, a stop button 105, and a heating button 107 for turning on and off the heater 13,
Buttons 109, 111, and 113 for setting the strength of the heater 13 are provided.

In addition, a set button to set the traction by the traction means 63
115, traction force adjustment buttons 117 and 119 for adjusting the traction force, a display unit 121 for displaying the traction force (kg), and the like are provided.
An intermittent button 123 and a foot massage button 125 are provided.

Incidentally, reference numeral 127 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 97, 99 of the operation panel 95, the head unit 3 is moved up and down, and the rubbing units 19, 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 101, the start button 1
By operating 03, the rubbing operation by the rubbing units 19 and 21 is started. 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 105 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.

By such an action, a desired lubrication is applied to the shoulder and a traction treatment for the neck is performed at the same time. First, the wire 67 is pulled out by a desired amount via the traction tool 81, and then the set button 115 is pressed. As a result, the wire 67 is locked by the electromagnetic clutch 65.

Next, the user operates the traction force adjustment buttons 117 and 119 to drive the traction drive motor 87 to perform desired traction. At this time, the display unit 121 displays the degree of traction by the traction force. Whether the traction is performed continuously or intermittently is selected by the continuous / intermittent button 123.

As described above, the safety devices by the limit switches 91 and 93 and the physical safety device (not shown) are operated as necessary to prevent the action of the traction force exceeding a certain level.

The timing of performing the traction treatment of the neck by the traction means 63 is arbitrary, and is performed not only at the same time as the massaging of the shoulder,
After shoulder rubbing, in some cases only neck traction treatment may be performed.

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.

Furthermore, in the case of the present embodiment, since the traction means 63 is also used in the masseter, traction treatment of the neck can be performed as necessary. Therefore, it is possible to perform a desired traction treatment without moving to a separately provided traction-only machine as in the related art, and to reduce the complexity of the treatment and to perform a more comprehensive treatment. . That is, synergistic effects are exerted by simultaneously performing shoulder massaging and neck traction, and a higher therapeutic effect can be expected.

Further, since the traction means 63 is provided with a safety device by the limit switches 91 and 93 and a physical safety device (not shown), it is possible to prevent the action of a certain or more traction force.

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.

Regarding the traction means 63, the configurations of the driving means and the traction tool are not limited to those illustrated.

(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.

Further, since the traction device is also provided with the traction means, traction treatment of the neck can be performed as needed. Therefore, it is possible to perform a desired traction treatment without moving to a separately provided traction-only machine as in the related art, and to reduce the complexity of the treatment and to perform a more comprehensive treatment. .
