Description

  The present invention relates to a chair-type massage apparatus having a plurality of fir balls for massaging the back and neck muscles on the backrest portion.

  Regarding the present invention, it is known in Patent Document 1 that only one of the pair of left and right airbags arranged for massage is inflated to twist the upper body. For example, in a state where the left forearm is fixed with an airbag, the upper left body is inflated by twisting the upper left airbag so that the stretch effect can be exerted. Similar massage devices are also disclosed in Patent Documents 2 and 3.

  In a chair-type massage device with a plurality of fir balls on the backrest, massage the neck, back, waist, etc. locally with the entire back applied to the backrest, or use fir balls on the spine. Massage can be performed while moving along. The massage operation by the kneading balls can be switched between the kneading operation and the striking operation, and the cycle speed can be changed to large and small as well as the operation speed and the massage intensity can be changed to large and small.

  When massaging the upper arm one by one, for example, inflating the upper right airbag on the back and twisting the upper body, inflating the left arm airbag in this state, concentrating the upper arm upper arm It is known from patent document 4 to massage directly.

JP 2007-260173 A (paragraph number 0025, FIG. 5) Japanese Patent Laid-Open No. 7-116214 (paragraph number 0091, FIG. 2) Japanese Patent No. 3614576 (paragraph number 0054, FIG. 2) JP 2003-325608 A (paragraph number 0042, FIG. 3)

  The massage operation using the kneading balls can be selected from a variety of operations that suit the user's preference, and the massage position can be changed in various ways by changing the left and right intervals of the kneading balls to large or small. However, since massage is performed by operating the left and right symmetrical rice balls in the same operation pattern, for example, the massage intensity at the left and right massage positions cannot be varied from left to right. Furthermore, when the massage position desired by the user when the spine is the center of symmetry is asymmetrical, massage with a fir tree cannot be performed accurately.

  In this regard, as seen in the massage device of Patent Document 1, when massage is performed with a ball while only one side of the airbag is inflated and the upper body is twisted, the massage position desired by the user is asymmetrical. Even massage can be done. However, in that case, the airbag on either the left or right side of the back is inflated and the upper body is twisted.For example, if the airbag on the left side is inflated, the back is not only pushed in the protruding direction of the kneading balls. The force to move to the right acts, and the body axis of the upper body shifts to the right. For this reason, there is a problem that the hit balls hit the positions not suitable for treatment, such as the spine and the scapula. In addition, for example, when inflating only the left airbag, the back is twisted, and the right side of the back moves to the opposite side of the protruding direction of the kneading balls, and the kneading balls hit the back too strongly than normal There is.

  An object of the present invention is to provide a chair-type massage device that can accurately massage even when the massage position desired by the user is asymmetrical while inheriting various massage modes of the conventional massage device. The object of the present invention is to prevent the kneading balls from strongly hitting the back etc. when performing massage with the asymmetrical massage mode, and also preventing the upper body from being displaced in the width direction even if the body axis is twisted. Then, it is providing the chair type massage apparatus which can massage comfortably.

  The massage device of the present invention includes a seat portion 2 and a backrest 4 that can be laid down with respect to the seat portion 2. Each of the seat portion 2 and the backrest 4 is provided with massage airbags 11, 15, and 16, and the backrest 4 is provided with a massage mechanism 14 provided with a kneading ball 13. An air supply source 29 for supplying inflation air to the airbags 11, 15, 16, a distribution device 30 for controlling a supply / exhaust state from the air supply source 29 to the airbags 11, 15, 16, and a distribution device 30 and the control means 31 which controls the operation state of the massage mechanism 14 in an integrated manner. Therefore, the control means 31 is in a state in which one of the pair of left and right airbags 15 and 16 provided on the backrest 4 is inflated and the other is in a semi-inflated state so that the upper body of the user is held obliquely. The massage mechanism 14 is actuated to provide a massage mode for massaging the back.

  Another massage device of the present invention includes a seat portion 2, a backrest 4 that can be laid down with respect to the seat portion 2, and body side holding portions 7 and 8 that hold the user's body side. Each of the seat 2, the back 4 and the body side holding parts 7 and 8 is provided with massage airbags 11, 15, 16, 17 and 18, and the back 4 is also provided with a massage mechanism 14 provided with the balls 13. . An air supply source 29 that supplies inflation air to the airbags 11, 15, 16, 17, and 18, and a supply / exhaust state from the air supply source 29 to the airbags 11, 15, 16, 17, and 18 And a control means 31 for controlling the operating states of the distribution device 30 and the massage mechanism 14 in an integrated manner. Therefore, at least one of the pair of left and right airbags 15 provided on the backrest 4 and the airbags 11, 17, and 18 provided on the seat portion 2 and the body side holding portions 7 and 8 are provided in the control means 31. One of them is inflated, and a massage mode is provided in which the massage mechanism 14 is operated to massage the back while the upper body of the user is held obliquely.

  The amount of protrusion of the kneading balls 13 from the backrest 4 in the massage mode is set smaller than the amount of protrusion of the kneading balls 13 from the backrest 4 in the normal massage state.

  In the massage mode, after the left and right airbags 15 provided on the backrest 4 are inflated at the same time, one of them is exhausted to be in a semi-inflated state, and the upper body of the user is held obliquely.

  In a state in which one of the right and left airbags 15 of the backrest 4 is inflated, the left and right airbags 17 and 18 provided on the body side holding portions 7 and 8 are inflated to press the user's body side, and the backrest 4 The massage mode is set so that the airbag 15 and the airbags 17 and 18 of the body side holding portions 7 and 8 cooperate to hold the upper body of the user obliquely.

  In the massage mode, setting is made so that the operation of the massage mechanism 14 is prohibited during supply and exhaust of each airbag.

  In the present invention, the airbags 11, 15, and 16 provided on the seat portion 2 and the backrest 4 can be inflated or contracted by the air supply source 29, the distribution device 30, and the control means 31, and at the same time the backrest 4. The operation state of the massage mechanism 14 provided in the control unit 31 can be integrated and controlled by the control means 31. In addition, a massage mode corresponding to the case where the massage position is asymmetrical is provided, one of the pair of left and right airbags 15 and 16 provided on the backrest 4 is inflated, and the back on the other side is In order to prevent tilting and shifting to the backrest side from the normal state, the other airbag is placed in a semi-inflated state to hold the upper body of the user diagonally, and in the state of being held diagonally, the massage mechanism 14 is operated to operate the back. I was able to massage.

  Therefore, according to the massage device of the present invention, the massage position desired by the user is asymmetrical as well as being able to perform massage in various massage modes as in the conventional massage device. Even when it hits the back, the massage can be performed close to the same hitting condition as when both the balls 13 hit equally. In the left-right asymmetric massage mode, the massage can be performed with only one of the left and right fir balls 13 in contact with the back, or the massage can be performed with different massage strengths on the left and right.

  In another massage device of the present invention, the air bags 11, 15, 16, 17, and 18 provided on the seat portion 2, the backrest 4, and the body side holding portions 7 and 8 are respectively connected to the air supply source 29 and the distribution device 30. And the control means 31 can be expanded or contracted, and at the same time, the operation state of the massage mechanism 14 provided on the backrest 4 can be integrated and controlled by the control means 31. In addition, a massage mode corresponding to the case where the massage position is left-right asymmetrical is provided, and is provided in any one of the pair of left and right airbags 15 provided in the backrest 4 and in the seat portion 2 and the body side holding portions 7 and 8. The displacement in the left-right direction of the user's body axis that occurs when at least one of the airbags 11, 17, 18 is inflated and any one of the pair of left and right airbags 15 provided on the backrest 4 is inflated. In the corrected state, the massage mechanism 14 is operated so that the back can be massaged.

  Therefore, according to the massage device of the present invention, the massage can be performed in various massage modes as in the conventional massage device, and even if the massage position desired by the user is asymmetrical, the user's A massage can be accurately performed by applying the balls 13 to the desired position. The upper body of the user is held obliquely by the cooperative action of the airbag 15 of the backrest 4 and the airbags 11, 17, 18 provided on the seat 2 and the body side holding parts 7, 8. It can be held more accurately at an angle. In the left-right asymmetric massage mode, the massage can be performed with only one of the left and right fir balls 13 in contact with the back, or the massage can be performed with different massage strengths on the left and right.

  In the left-right asymmetric massage mode, the upper body of the user is held obliquely, so that the kneading balls 13 tend to hit the side of the back more strongly than usual as described above. Therefore, in a left-right asymmetric massage mode, massage is performed by setting the amount of protrusion of the kneading balls 13 from the backrest 4 smaller than the amount of protrusion of the kneading balls 13 from the backrest 4 in a normal massage state. Thus, if massage is performed in a state where the amount of protrusion from the backrest 4 of the kneading balls 13 is small, the massage strength by the kneading balls 13 can be prevented from becoming excessive, and the massage can be performed comfortably. Further, it is possible to avoid the fir ball 13 from directly hitting the spine.

  In a left-right asymmetric massage mode, as in a conventional massage device, when inflating one of the left and right airbags with the back resting on the backrest, for example, inflating the left airbag, the inflating airbag As a result, not only the back is pushed in the protruding direction of the kneading balls 13, but also a force that moves in the right direction acts, and the body axis of the upper body is shifted in the right direction. However, if the left and right airbags 15 provided on the backrest 4 are inflated at the same time, it is possible to prevent the lateral pressing force from acting when the airbag 15 is inflated. Therefore, if the left and right airbags 15 are inflated at the same time, one of them is exhausted to a half-inflated state, and the upper body of the user is held diagonally while preventing the body axis of the upper body from shifting in the width direction. You can tilt your upper body more easily. Therefore, it is possible to accurately and comfortably massage with a fir tree ball.

  When the upper body of the user is held obliquely by the left and right inflated airbags 15 of the backrest 4, the left and right airbags 17 provided on the body side holding portions 7 and 8 are inflated to expand the shoulders. According to the massage mode to be pressed against the backrest, it is used in a cooperative action between the airbag 15 of the backrest 4 and the airbags 17 and 18 of the body side holding portions 7 and 8 while preventing the above-described left and right displacement of the body axis. The upper body of the person can be securely held at an angle. Therefore, in a left-right asymmetric massage mode, the upper body of the user can be securely held and the upper body can be prevented from shaking and the massage effect by the kneading balls 13 can be improved.

  If the operation of the massage mechanism 14 is prohibited during the supply / exhaust of each air bag, the discomfort such as the fir ball 13 strongly hits an unexpected position while the upper body moves due to the air supply / exhaust of the air bag. Therefore, it is possible to accurately and comfortably massage with a kneading ball in a left-right asymmetric massage mode.

(Example) FIG. 1 thru | or FIG. 7 shows the Example of the chair type massage apparatus based on this invention. In FIG. 2, the massage apparatus includes a machine base 1 placed on the floor surface, a seat 2 and an armrest 3 provided on the upper part of the machine base 1, and an overturnable backrest 4 disposed at the rear part of the seat 2. And a leg rest part 5 disposed on the front side of the seat part 2, a footrest 6 disposed at the lower end of the leg rest part 5, and the like. On the upper left and right sides of the backrest 4, shoulder support portions (body side holding portions) 7 are provided so as to protrude forward of the chair.

  As shown in FIG. 3 and FIG. 4, a laterally long airbag 10 that massages the left and right thighs and a pair of airbags 11 that individually massage the left and right hips are provided inside the seat portion 2. Inside the armrest 3, there is provided an airbag 12 for massaging with the forearm sandwiched between the upper and lower arms. Inside the backrest 4, there are provided a massage mechanism 14 having a pair of left and right fir balls 13, a pair of left and right airbags 15 for massaging the back, and a pair of left and right airbags 16 for massaging the waist. An airbag 17 for massaging the shoulder and upper arm is provided inside the shoulder receiving portion 7.

  The leg rest 5 is formed with a pair of left and right lower leg grooves 19 that are opened forward, and a pair of upper and lower airbags 20 for massaging calves are provided inside the opposing surfaces of both lower leg grooves 19. It is. A pair of left and right foot receiving grooves 21 are recessed in the footrest 6 so as to open upward, and an airbag that massages ankles and arches on each of the opposed peripheral surface of the foot receiving groove 21 and the groove bottom. 22 is provided.

  The backrest 4 can be tilted to an arbitrary position between a standing position shown by a solid line in FIG. 2 and a rearward tilt position shown by an imaginary line in FIG. 2 by a reclining mechanism (not shown). Similarly, the leg rest 5 can be turned and displaced at an arbitrary position between a turning standby position indicated by a solid line in FIG. 2 and a turning position indicated by an imaginary line in FIG. 2 by a turning mechanism (not shown). In the state in which the leg rest part 5 is pivotally displaced, the footrest 6 can be extended according to the length of the user's lower leg, and the leg rest part 5 is extended and contracted by motor power in conformity with the position of the calf. be able to.

  The massage mechanism 14 can be moved up and down along a guide member 25 (see FIG. 2) disposed inside the backrest 4 and can be swung back and forth around the swing shaft 26 shown in FIG. By changing the front-rear position, the amount of protrusion from the back of the fir ball 13 can be changed to a large or small amount. As the amount of protrusion of the kneading balls 13 increases, the massage strength (pressing force or tapping force) increases. In a normal massage mode, the amount of protrusion of the kneading balls 13 is changed to a larger or smaller size to increase the massage strength. Can be set to weak. Moreover, the massage position can be changed by changing the left-right distance of the kneading balls 13 to large or small.

  As shown in FIG. 6, an air supply source 29 that supplies inflation air to the airbags 10 to 22 and a distribution that switches between supply and exhaust states of the inflation air to the airbags 10 to 22 are provided in the machine base 1. The apparatus 30 and the control means 31 which integrate and control the operating state of the distribution apparatus 30 and the massage mechanism 14 are provided. A number of massage modes are pre-programmed in the control means 31. Although not shown, the distribution device 30 is configured by a group of electromagnetic valves provided corresponding to the airbags 10 to 22. By switching the electromagnetic valves between the supply state and the exhaust state, The bags 10-22 can be inflated or deflated.

  Among a group of airbags, an airbag 11 that supports the buttocks, an airbag 12 that supports the forearm, an airbag 15 that supports the back, an airbag 16 that supports the waist, and an airbag that supports the shoulder and upper arm. 17 can inflate each of the left and right airbags 11 to 17 simultaneously or independently. Similarly, the airbag 20 that supports the calves and the airbag 22 that supports the legs can inflate each of the left and right airbags 20 and 22 simultaneously or independently.

  According to the massage device having the above-described configuration, the user can select a desired massage mode with the remote controller, or can input a desired massage condition and change the operation state of the massage mechanism 14 in various ways, so that the neck, back, and back muscles can be changed. The waist can be massaged with the kneading balls 13. Similarly, by changing the operating states of the airbags 10 to 22 in various ways, it is possible to massage the shoulders, arms, back, hips, hips, upper legs, calves, ankles, and arches. Of course, the fir ball 13 and the airbags 10 to 22 can be actuated simultaneously to massage a plurality of parts of the body at the same time. By stretching the backrest 4 or turning the leg rest 5 while holding the calf, the upper body and legs can be stretched.

  In the massage apparatus of the present invention, in addition to the massage mode described above, when the neck, back, back muscles, and waist are massaged with the kneading balls 13, it is possible to locally massage the asymmetric massage position. In that case, one of the pair of left and right airbags 15 and 16 provided on the backrest 4 is inflated, and at least one of the airbags 11 and 17 provided on the seat portion 2 and the shoulder support portion 7. One of them is inflated and the upper body of the user is held diagonally while correcting the displacement of the body balls and the balls 13, and in this state, the massage mechanism 14 is operated to massage the back. The detail of this massage aspect is demonstrated below.

  In addition, when the left-right asymmetric massage mode is selected, the protruding amount of the kneading balls 13 from the backrest 4 is set smaller than the protruding amount of the kneading balls 13 when performing normal massage. At that time, it is desirable to change only the protrusion amount of the kneading balls 13 without changing the display of strength and weakness in the remote controller. This is because the user's sensation is strongly felt in the left-right symmetric massage mode, and the display content and the sensation are prevented from causing discomfort. Even in this case, either “medium” or “weak” is selected as the massage strength. Use in the “strong” position in a normal massage state may be prohibited. In addition, when the operation mode of the kneading balls 13 is a tapping operation, either one of the kneading balls 13 protrudes from the backrest 4 more greatly than the other, but by performing the kneading operation in that posture, the left and right firding is performed. The massage intensity of the ball 13 can be adjusted and changed.

<Massage aspect 1> As shown to Fig.7 (a), the left-right paired airbag 15 of the backrest 4 is expand | swelled simultaneously. Next, as shown in FIG. 7 (b), the left airbag 15 is exhausted into a semi-inflated state toward FIG. 7, and the upper body of the user is held obliquely. At this time, the amount of air exhausted from the airbag 15 may be adjusted, and the inflated state of the airbag 15 may be adjusted according to the difference in the physique of the user. Further, in conjunction with the exhaust operation of the airbag 15, as shown in FIG. 7C, the airbag 17 on the left side of the shoulder receiving portion 7 is inflated, and the user's shoulder is pressed against the backrest 4. As a result, the upper body of the user is firmly held obliquely by the cooperative action of the airbag 15 of the backrest 4 and the airbag 17 of the shoulder support 7 while moving to the right. As described above, after the upper body is held obliquely, massage is performed with the ball 13 even when the massage mechanism 14 is activated. It is preferable to prohibit the massage mechanism 14 in this massage mode from operating during supply and exhaust of the airbag 15. However, if necessary, the massage mechanism 14 may be operated while the airbag 15 is being supplied and exhausted.

  In this massage mode, massage can be performed with only one of the left side balls 13 facing the back as viewed in FIG. Alternatively, the massage can be performed in a state where the massage intensity of the left side ball 13 is large and the massage intensity of the right side ball 13 is low as viewed in FIG. When the massage position is shifted to the left and right on the upper and lower sides of the back, the left and right intervals of the kneading balls 13 are adjusted and changed while the massage mechanism 14 moves up and down, so that the kneading balls 13 can accurately touch the massage position. At this time, the operation mode of the kneading balls 13 can be selected from either a finger pressure operation, a kneading operation or a hitting operation.

<Massage mode 2> Like the massage mode 1, a pair of left and right airbags 15 and 16 provided on the back and waist of the backrest 4 are inflated simultaneously. Next, the left airbags 15 and 16 are evacuated to a semi-inflated state toward FIG. 3, and the upper body of the user is held obliquely. Even if the massage mechanism 14 is activated in this state, massage is performed with the balls 13.

<Massage aspect 3> Like the massage aspect 1, the pair of left and right airbags 15 provided on the back of the backrest 4 are inflated simultaneously. Furthermore, the airbag 11 located in the left side toward FIG. 3 among the airbags 11 provided in the seat portion 2 is inflated. Next, as shown in FIG. 7B, the left airbag 15 provided on the back of the backrest 4 is evacuated to hold the upper body of the user diagonally. Even if the massage mechanism 14 is activated in this state, massage is performed with the balls 13.

<Massage aspect 4> Like the massage aspect 1, the pair of left and right airbags 15 provided on the back of the backrest 4 are inflated simultaneously. Furthermore, the airbag 18 located in the left side toward FIG. 8 among the airbags 18 provided in the seat side part (body side holding part) 8 is inflated. Next, as shown in FIG. 7B, the left airbag 15 is evacuated to hold the upper body of the user diagonally. Even if the massage mechanism 14 is activated in this state, massage is performed with the balls 13. Note that the air bag 15 on the exhaust side in the massage modes 1 to 4 may be in a semi-inflated state or a fully exhausted state. Furthermore, in the massage modes 1, 3, and 4, only one of the pair of left and right airbags 15 provided on the back of the backrest 4 may be inflated at the same time.

  The massage modes 1 to 4 can hold the user's upper body diagonally by combining the modes, and in that case, hold the user's upper body diagonally more accurately and without difficulty. Can do. For example, when the user's upper body is held obliquely as shown in FIG. 7 (c), in the seat side portion 8, only the left airbag 18 is inflated toward FIG. 8 to assist the upper body torsion. can do. That is, the airbag 18 of the seat side portion 8 on the same side as the airbag 17 to be inflated of the shoulder support portion 7 is inflated. As shown in FIG. 8, in the massage apparatus that does not include the shoulder support portion 7, the airbags 15 and 16 of the backrest 4, the seat portion 2, and the airbag 18 of the seat side portion 8 are inflated, It is preferable to hold the upper body diagonally. When the upper body of the user is held in an oblique posture in which the left and right are reversed, the left and right positions of the airbags 15 and 17 to be inflated are reversed from those described above. The various massage modes and the combination modes are set in the control unit 31 in advance. In this invention, holding means not only holding firmly by the body side holding portions such as the shoulder receiving portion 7 and the seat side portion 8 but a state in which the body is held diagonally only by the airbag 15 of the backrest 4. Is included.

  In the above-described embodiment, the massage mechanism 14 including the pair of left and right rice balls 13 has been described. However, the structure of the massage mechanism 14 is not limited, and the massage mechanism 14 includes at least two kneading balls 13. Just do it. The semi-inflated state in the present invention includes an inflated state excluding a state where the airbag is completely inflated and a state where the airbag is completely exhausted. The arrangement form of the airbags 15 and 16 in the backrest 4 and the arrangement form of the airbags 10 and 11 in the seat portion 2 do not need to be the arrangement forms shown in the embodiments. For example, a pair of left and right airbags can be disposed before and after the seat portion 2.
