Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a massage machine.

[0002]

2. Description of the Related Art As described in, for example, Japanese Patent Application Laid-Open No. 6-190012, a chair-type massage machine having a massage mechanism for vertically moving a backrest of a chair has been known. This massage mechanism includes a pair of left and right arms protruding to the user side, and a treatment element provided at the distal end of the arm so as to be rotatable around a left-right axis. Neck, shoulders, back,
Massage such as kneading and tapping is performed on the waist.

[0003] This massage machine has an automatic treatment function for automatically executing a series of massage operations (such as continuous operations such as kneading and tapping) based on the program by storing the movement of the treatment element and the operation form in advance as a program. Have. In addition, prior to performing automatic treatment, a function for automatically determining the height of the shoulder of the user, such as a neck, etc., so that the height at which the treatment element performs a massage operation can be automatically changed according to the sitting height of the user. It has a function to detect the width shape of the body so that an appropriate kneading operation according to the width can be performed.
The medical device includes a pressure sensor (hereinafter, first sensor) for detecting pressure in the front-rear direction received by the treatment element from the body, and a pressure sensor (hereinafter, second sensor) for detecting pressure in the left-right direction.

More specifically, before performing automatic treatment, the treatment element is moved up and down while the amount of projection of the treatment element toward the human body is kept constant, so that the treatment element can be moved to the shoulder or back of the user. The first sensor detects the pressure in the front-rear direction received from the first sensor, determines the position of the shoulder from the distribution of the detected pressure in the vertical direction, and sets this position as the origin of the massage operation. A series of massage operations programmed downward were sequentially performed. Further, the second sensor detects the force of pinching the user's body between the left and right treatment elements, and adjusts the distance between the left and right treatment elements along the side of the body so that the pressure is constant. By moving the body in the vertical direction, the width of the body is determined from the distance between the left and right treatment elements, and control is performed by feeding back this data so that massage with an appropriate kneading force can be performed. . Further, since the second sensor detects the pressure in the left-right direction, the second sensor can also detect the strength of kneading (kneading force).

[0005]

As described above, the conventional massage machine is capable of performing an appropriate massage operation by recognizing the shape and the like of the user's body using the first and second sensors. Although useful, the pressure sensing structure has the following disadvantages. That is, this massage machine swings the arm back and forth or moves left and right by the pressure in the front-back direction or the left-right direction that the treatment element receives from the body,
The first and second sensors are configured to detect the displacement of the spring compressed by the swing or the movement, and an arm,
The structure becomes complicated due to the interposition of a plurality of members such as springs, and the bending of the arms and the like and the play at the connection portion of each member,
There has been a problem that the pressure is absorbed due to play or the like and the detection accuracy is impaired.

Therefore, it is difficult to accurately determine the shape of the body, and when the kneading force is detected by the second sensor, the accuracy is impaired. It should be noted that a pressure sensor incorporated in the treatment element is also known in the related art (for example, see Japanese Patent No. 2511451) because the number of members interposed between the sensor and the treatment element is small. Although it is superior in terms of detection accuracy, since the sensor has a built-in sensor, the structure of the treatment element must be complicated and special, and since the treatment element rotates, the wiring structure of the pressure sensor Was also complicated.

On the other hand, in the conventional massage machine, the second
Although it is possible to massage with appropriate kneading force by having a sensor, this second sensor is
It is used only to detect the width and the like of the human body, and is provided separately from the first sensor that detects the vertical position of the user's shoulder. Therefore, two types of sensors are required. This increases the cost and hinders the downsizing. The present invention has been made in view of the above-described circumstances, and provides a massage machine that has a simple structure for detecting a load applied to a treatment element and that can accurately detect the load. This is the first purpose.

In addition, the present invention provides a detector for detecting the load on the treatment element in the left-right direction to enable detection of the kneading strength and the like. A second object of the present invention is to provide a massage machine that reduces costs and reduces the size by determining the position.

[0009]

The present invention employs the following technical means to achieve the first object. That is, the massage machine according to the present invention includes a treatment element for massaging a user's body and a support for supporting the treatment element via a support shaft, and the support in the axial direction of the support shaft. A detector for detecting the axial load applied to the treatment element between the treatment element and the treatment element.

According to this, the load on the treatment element in the axial direction of the support shaft can be detected with a simple structure, and the number of members interposed between the detector and the treatment element can be eliminated or reduced. Can be improved. Therefore, when the support shaft is arranged with the axial direction oriented in the left-right direction (the width direction of the body), the strength of kneading by the treatment element can be accurately determined, and this detection value is fed back. By performing the control, a more appropriate kneading operation can be performed. Further, the present invention employs the following technical means to achieve the second object.

That is, the massage machine according to the present invention comprises:
A massager for massaging a user's body, wherein the massager is provided movably in the height direction along the body, and a detector for detecting a left-right load applied to the massager. While the treatment element is moved in the height direction, a load in the left-right direction received by the treatment element from the body is detected by the detector, and the position of the specific part of the body in the height direction based on the detection is detected. Is determined.

In this case, when the massager performs the kneading operation, a load in the left-right direction is applied to the massager as a reaction force of the kneading force, and the load is detected by the detector to determine the intensity of the kneading. Can be determined. On the other hand, when the treatment element is pressed against the body by moving the treatment element in the height direction, a load is applied from the body to the treatment element as a reaction force. This includes not only the frontal component and the vertical component, but also the horizontal component due to the structure of the treatment element, the inclination of the support shaft, and other factors. In addition, the load may cause a lateral force. . Therefore, by detecting such a load in the left-right direction by the detector, the position of the specific part of the body in the height direction can be determined based on the detection.

For example, when determining the position (height) of the shoulder of the user, the treatment element is lowered from the head side of the user to the shoulder, and the treatment element is brought into contact with the upper surface side of the shoulder. At this time, a load having a left-right component is applied to the treatment element as a reaction force of the force applied by the treatment element to the shoulder, and the load is detected by the detector, and the height of the treatment element at the time of the detection is detected. May be determined. Therefore,
The massage machine according to the present invention is such that the detector capable of detecting the kneading strength and the like is also used for determining the height position of the shoulder and the like, compared with the case where these are performed using individual sensors. , Cost and size can be reduced.

In the above case, the treatment element is supported on the support via a support shaft having a left-right axis, and the detector is disposed between the support and the treatment element in the axial direction of the support shaft. Is preferably provided. As a result, accurate load detection can be performed with a simple structure. Further, according to the present invention, the treatment element is provided rotatably around an axis of the support shaft, and the detector is provided on the support body side in a state where movement around the axis of the support shaft is restricted. It is characterized by being provided. This makes it possible to easily perform wiring and the like of the detector with a simple structure.

[0015] The present invention is characterized in that the detector is provided in a state where a preload is applied, whereby the axial direction between the support and the treatment element is reduced. It is possible to prevent the detection accuracy from being impaired due to play or play.

The treatment element 26 performs a beating operation through the intermediary.

The power from the prime mover 23 is selectively transmitted to the kneading operation shaft 21 and the hitting operation shaft 22 via a clutch in the drive unit 20. An individual and dedicated prime mover may be provided for 21 and 22. In the massage machine 1 of the present invention, each treatment element 26 provided on the upper side of the left and right support arm 25 is provided.
A detector 40 is provided for both or one of the two to detect the load applied to the treatment element 26 in the left-right direction.
1 and 2 showing the attachment structure of the treatment element 26, the support arm 25 is provided with the support shaft 30 having a left-right axis and protruding left and right inward. A boss 31 is provided at the center thereof, and the boss 31 is rotatably fitted on the support shaft 30. At the tip of the support shaft 30, a mounting nut 32 for preventing the treatment element 26 from being removed is provided with a washer (pressing member) 32a.
Are screwed together.

The boss body 31 has a cylindrical portion 31a fitted to the inner periphery of a through hole formed in the center of the treatment element 26, and a cylindrical portion 3a.
The left and right sides of 1a have a flange portion 31b that sandwiches the treatment element 26, and the central portion of the cylindrical portion 31a is divided into two right and left parts. Further, the outer peripheral surface of the treatment element 26 is formed as an arc-shaped inclined surface 26a which shifts radially inward toward the left and right inner sides. The detector 40
For example, as shown in FIG. 2B, a pressure-sensitive conductive elastomer 40a in which conductive particles are blended with an elastic material such as rubber as an insulator is attached between a pair of electrodes 40b. A pressure (pressure-sensitive) sensor is used. The pressure sensor 40 is connected to the support arm 25
And a boss body 31 are formed in a donut disk shape so as to fit over the support shaft 30, and the left and right outer surfaces thereof are
5 is in contact with the left and right inner side surfaces.

The left and right inner surfaces of the pressure sensor 40 are covered with a donut disk-shaped cover plate 36.
6 are in contact with the boss body 31. Cover plate 36
A plurality of detent protrusions 42 project from the outer surface of the support arm 25, and are inserted through insertion holes 43 formed in the support arm 25 movably in the axial direction of the support shaft 30. Thereby, the cover plate 3
Reference numeral 6 indicates that the pressure sensor 40 can be pressed to the left and right outside in a state where the rotation about the support shaft 30 is restricted.
The cover plate 36 not only functions as a pressing member that presses the pressure sensor 40 but also prevents direct contact between the rotating treatment element 26 and the pressure sensor 40 to prevent wear of the pressure sensor 40 and the like. It has a function as a protection member.

Between the boss body 31 and the washer 32a, spacer members 35, 4 for maintaining a space therebetween are provided.
1 is provided so as to be fitted on the support shaft 30. The spacer members 35 and 41 include a first member 35 formed in a donut disk shape from a synthetic resin material such as polyethylene, and a second member 41 formed from an elastic material such as polyethylene rubber or sponge rubber. The left and right inner side surfaces of the first member 35 come into contact with the boss body 31. Second member 41
Is compressed in the axial direction by tightening the mounting nut 32 on the support shaft 30, and presses the pressure sensor 40 via the first member 35, the boss body 31 and the cover plate 36 by the elastic restoring force. It is like
Accordingly, pressure is applied to the pressure sensor 40 in advance even when the treatment element 26 is not receiving an external force in the left-right direction.

The first member 35 and the cover plate 36 are preferably made of a material having a small frictional resistance, or have a structure in which at least a contact surface with the boss body 31 is subjected to a low friction treatment. The rotation of the treatment element 26 around the support shaft 30 can be performed smoothly. With the above-described configuration, when the treatment element 26 performs the kneading operation, a load in the left-right direction is applied to the treatment element 26 by a reaction force from the user side to the movement in the left-right direction. At this time, the treatment element 26 is
Is pressed by the pressure sensor 40, and the pressure is detected by the pressure sensor 40.

Since the magnitude of the pressure detected in this manner is proportional to the strength of the kneading, the detected value is fed back to the control unit to perform appropriate kneading control (for example, when the detected value is large). In such a case, it is possible to perform control such as reducing the speed), and a more effective kneading operation can be performed. Since the pressure sensor 40 is pre-applied to the pressure, the treatment element 26 receives, for example, play due to play or play between the treatment element 26 and the support arm 25 in the axial direction. Accurate pressure detection can be performed without impairing load detection accuracy.

The pressure sensor 40 is provided not on the treatment element 26 rotating around the support shaft 30 but on the support arm 25 side (substantially, the support shaft 30), and the cover plate 36 rotates around the support shaft 30. Since the movement is regulated, the position of the pressure sensor 40 is also regulated without rotating by the rotation of the treatment element 26, whereby the pressure sensor 4
0 can be easily wired, and the shape of the treatment element 26 is not particularly complicated. The pressure sensor 40 can be used to determine a height position such as the shoulder S of the user in order to perform a massage operation according to the physique of the user.

That is, when starting the massage operation, the treatment element 26 is moved downward from the head side of the user, so that the treatment element 26 on the upper side of the support arm 25 is shouldered.
A load F is applied to the treatment element 26 as a reaction force of the pressing force acting on the shoulder S. The load F mainly has a vertical component.
6 is supported in a cantilever shape on the left and right outer sides thereof, a moment as shown by an arrow M is generated, and the moment M is further treated through a gap between the support shaft 30 and the boss body 31. A force is generated such that the upper side of the child 26 is inclined right and left outward.

The load F is substantially 2 due to factors such as an inclined surface 26a on the outer periphery of the treatment element 26 and a slight inclination applied to the support shaft 30, elastic deformation of the treatment element 26 itself, and the like.
As shown by the dashed line, it includes a left-right component that presses the treatment element 26 right and left outward. The force for tilting the treatment element 26 and the force for pressing the treatment element 26 to the left and right sides are detected by the pressure sensor 40 via the cover plate 36, and the movement position (height) of the massage mechanism 7 (treatment element 26) at the time of the detection is detected. ) Makes it possible to determine the height of the user's shoulder S. Therefore, by setting the height of the shoulder S as the reference position of the massage operation, massage according to the user's physique can be performed.

That is, the pressure sensor 40 according to the present invention
Is used for both the detection of the load in the kneading operation and the determination of the height of the shoulder, compared with the case where these are performed using separate pressure sensors, cost reduction,
It is possible to reduce the size and the like. In addition,
In the above description, the height position of the shoulder S is determined by detecting the load received from the user's shoulder S by the pressure sensor 40. However, the load received from the back and waist of the user is detected by the pressure sensor 40. At the same time, a configuration may be adopted in which the height position such as the waist is determined by analyzing the pressure distribution.

Further, the height of the shoulder may be determined in the process of moving the treatment element 26 upward from the waist side of the user. In this case, the treatment element 26 is separated upward from the shoulder and the load is increased. The shoulder position can be determined from the moving position of the treatment element 26 at the time when is not detected. FIG. 6 shows a second embodiment of the present invention. In the present embodiment, the pressure sensor 40 is set not on the entire circumference around the support shaft 30 but on the treatment element 26.
The pressure sensor 40 is partially provided so as to correspond to the upper part of the support base 33 provided on the support shaft 30.
And is attached to the support arm 25 side via a.

The support table 33 is formed in the shape of a donut disk, is fitted over the support shaft 30, and has a concave storage portion 34 in which the pressure sensor 40 can be fitted. are doing. Further, a concave portion 43a is formed in the front and rear portions of the inner side surface, and the detent projections 42a formed in the front and rear portions of the left and right outer surfaces of the cover plate 36 are provided with the concave portions 43a.
By fitting into a, relative rotation between the support base 33 and the cover plate 36 is prevented. A plurality of second detent projections 42b are provided on the left and right outer surfaces of the support base 33, and the second detent projections 42b are inserted into insertion holes 43b formed in the support arm 25. The rotation of the support 33 around the support shaft 30 is thereby restricted.

When the pressure sensor 40 is fitted in the storage section 43, a slight gap is formed between the support base 33 and the cover plate 36. Can be pressed. In the present embodiment, the pressure sensor 40 is partially
Although the detection range of the load is smaller than that of the first embodiment, since the pressure sensor 40 is provided corresponding to the upper side of the treatment element 26, the treatment element 26 Treatment element 26 caused by contact with
The force which inclines the upper side of the right and left outwards can be reliably detected.

Further, since the pressure sensor 40 has a small and simple structure, the cost can be reduced. Similarly to the first embodiment, the rotation of the pressure sensor 40 around the support shaft 30 is restricted. Wiring can also be easily performed.
Since the pressure sensor 40 is pressed only in the gap between the support base 33 and the cover plate 36, even if an excessive load is applied to the treatment element 26, the overload acts on the pressure sensor 40. The pressure sensor 4
0 can be prevented from being damaged.

The support table 33 is provided with a support arm 25.
May be formed integrally with the support arm 25, or may be separately fixed to the support arm 25 by welding or the like.
Similarly, the support shaft 30 may be formed integrally with the support arm 25, or may be separately fixed by welding or the like. FIG. 7 shows a third embodiment of the present invention.

It is compressed and further presses the pressure sensor 40 by its elastic restoring force to apply a preload. The cover plate 36 can enter the storage portion 34 by being elastically deformed. When the surface of the pressure sensor 40 protrudes from the surface of the support 33, it is flush or concave. However, the pressure sensor 40 can be pressed. However, since the amount of the cover plate 36 entering the storage portion 34 is naturally limited, even if an excessive load is applied to the treatment element 26, an overload to the pressure sensor 40 is prevented.

In the present embodiment, since the pressure sensors 40 are provided at two positions above and below the support table 33, when performing a kneading operation or the like, the left and right directions of the upper or lower part of the treatment element 26 are applied. Can be individually detected. That is, the kneading operation by the treatment element 26 performs, for example, a circumferential motion having not only the left-right direction but also the up-down direction component as shown by arrows C and C ′, and its directionality (kneading down C and kneading up C ′) and Depending on the part to be massaged (shoulder, back), etc., a different load is applied to the upper part or the lower part of the treatment element 26 in a complicated manner. At this time, the upper and lower pressure sensors 40H, With 40L, the degree of load applied to each part is detected in detail each time, and the information is fed back to the control unit, so that fine-grained kneading control can be performed.

In the present embodiment, as indicated by a two-dot chain line, pressure sensors 40 may be provided on the front and rear portions of the support 33, respectively, so that more detailed pressure detection can be performed. become. Further, in the present embodiment, it is preferable to provide the spacer member (first member) 35 as shown in the first and second embodiments between the cover plate 36 and the boss body 31. 26 can be smoothly rotated, and the cover plate 36 can be prevented from rotating with the rotation. The present invention is not limited to the above-described embodiment, and can be appropriately changed in design.

For example, the spacer members 35 and 41 in the first and second embodiments can be omitted.
In this case, it is preferable to apply a preload to the pressure sensor 40 with the boss body 31 of the treatment element 26 by fastening the mounting nut 32. Further, it is also possible to omit the support table 33 in the second and third embodiments and directly attach the pressure sensor 40 to the plate surface of the support arm 25. The treatment element 26
May be non-rotatably attached to the support shaft 30. In this case, the pressure sensor 40 can be attached to the side surface of the treatment element 26 on the support arm 25 side.

The massage mechanism 7 does not perform a beating operation,
A massage operation may be performed alone, another massage operation may be performed, or the treatment element 26 may be driven by fluid pressure using an air cell or the like.
