  Hereinafter, the massage machine of the present invention will be described with reference to the drawings.

(First embodiment)
1 (a) and 1 (b) show a massage machine 1 according to the first embodiment of the present invention, FIG. 2 shows a swing generation part 3 of the massage machine 1, and FIGS. 4 shows the movement of the movable arm 31 of the swing generation unit 3, FIG. 4 shows the state of the unwinding operation by the massage machine 1, and FIGS. The massage machine 1 includes a swinging unit 2 that imparts a passive swing motion to the treatment target site and a swinging motion of the swinging unit 2 to relieve joint and / or muscle tension of the treatment target site of the human body. And a posture holding means for holding the posture of the user in a state where the target part of the loosening operation is weakened prior to the start of the loosening operation by the rocking portion 2. Hereinafter, each structure and operation | movement of the massage machine 1 are explained in full detail.

  As shown in FIGS. 1 (a) and 1 (b), the massage machine 1 has a chair shape with a footrest, a base 10 serving as a fixed base with respect to the floor, a backrest portion 11, and a seat portion. 12, a footrest 13 provided with an airbag for massaging the lower leg, an armrest 14, and a headrest 15 provided on the backrest. The backrest 11 is equipped with a well-known massage mechanism (not shown) for carrying out a kneading exercise with a kneading ball, for example, for massaging the upper body of the user. In the following, the kneading movement by the kneading balls can include actions that can be performed by the kneading balls, such as a hitting action, a back stretching action, a pinching action, and a sanding action.

  In the massage machine 1, the backrest part 11, the seat part 12, and the footrest 13 are each provided with a known reclining mechanism (not shown) that can freely change the angle with the floor surface. Since the massage machine 1 provides the maximum unwinding effect according to the joint and / or muscle region that is the object of the unwinding operation, the reclining mechanism can keep the posture of the user in an optimal state. . That is, the reclining mechanism is configured as posture holding means for holding the posture of the user in a state where the target portion of the loosening operation is weakened.

  The above-described swinging portion 2 is provided on the upper rear portion (the backrest portion 11 side) of the seat portion 12, and imparts a passive swinging motion to the waist of the user. Further, the above-described swing generation unit 3 that swings the swing unit 2 is provided inside the base 10 below the seat 12. In addition, a control unit 4 that controls the massage mechanism mounted on the swing generation unit 3 and the backrest unit 11 is disposed inside the base 10. The swing part 2 is disposed independently of the seat part 12 and is three-dimensionally moved in the vertical direction, the left-right direction, the front-rear direction, and the direction in which these are combined by the swing generation part 3 in the base 10. It is possible to give an appropriate swing.

  The swinging portion 2 and the seat portion 12 are, for example, highly stretchable cloth or synthetic leather so that fingers or clothes are not caught in the gap between the swinging portion 2 and the seat portion 12. Preferably it is covered by a cover consisting of Further, in order to prevent the seating position of the user from shifting due to swinging, the swinging portion 2 is disposed in a concave shape with respect to the upper surface of the seating portion 12, or the cover surface is subjected to anti-slip processing. It is desirable.

  As shown in FIG. 2, the above-described swing generation unit 3 includes a base plate 30, a movable arm 31, and a swing base 32 that are horizontally arranged in a three-layer structure in order from the bottom. These are described below. As described above, they are linked to each other and swing relative to each other in a horizontal plane. The base 30 is fixed with a motor M1 serving as a driving source for rocking and a motor M2 for changing the amplitude of rocking. An eccentric cam 35 is attached to the output shaft of the motor M1, and the eccentric cam 35 is fitted to one end of a long hole 31a (see FIG. 3A) of the movable arm 31. The movable arm 31 fitted to the eccentric cam 35 performs a swing motion (oscillating motion) in a plane perpendicular to the output shaft of the motor M1 by the rotation of the motor M1.

  A horizontal screw shaft 33 is attached to the output shaft of the motor M2, and a nut 34a below the fulcrum pin 34 is screwed to the screw shaft 33. The fulcrum pin 34 is fitted in the long hole 30 a of the base 30 and the long hole 31 a of the movable arm 31. The fulcrum pin 34 moves along the screw shaft 33 in the long holes 30a and 31a as shown by the arrow a by the rotation of the screw shaft 33 accompanying the rotation of the motor M2. The swing base 32 and the movable arm 31 are coupled to each other so as to be rotatable around the axis of the coupling pin 36 by a coupling pin 36 provided in the vicinity of the other end of the long hole 31 a of the movable arm 31. Further, one side of the swing base 32 is slidably fixed by a slide guide mechanism 37.

  Under the above configuration, when the eccentric cam 35 is rotated by the motor M1, the movable arm 31 swings around the fulcrum pin 34 as the rotation center, as shown in FIGS. When the amplitude changing motor M2 is driven to change the position of the fulcrum pin 34 in the long holes 30a and 31a, the swing amplitude of the movable arm 31 is changed. That is, when the position of the fulcrum pin 34 is close to the eccentric cam 35, the swing width S of the other end of the movable arm 31 is increased, and when the fulcrum pin 34 is separated from the eccentric cam 35, the swing of the other end of the movable arm 31 is increased. The width S is reduced.

  Accordingly, since the swing base 32 is connected to the other end of the movable arm 31 by the connecting pin 36 and is also guided in the sliding direction by the sliding guide mechanism 37, the position of the fulcrum pin 34 is increased with the rotation of the motor M1. A swinging motion is performed as indicated by an arrow b under an amplitude (stroke) corresponding to. And by making the rotation speed of the motor M1 variable, the oscillation frequency of the oscillation base 32 becomes variable. By fixing a member having a predetermined shape that fits the upper surface of the seat portion 12 to the swing base 32, the swing portion 2 described above can be configured.

  In the above-described example, the swing generation unit 3 is a mechanism example in which the swing unit 2 swings in one direction along the sliding guide mechanism 37, but is not limited thereto. . For example, the rocking part 2 that rocks in the directions of the three axes X, Y, and Z orthogonal to each other can be realized by connecting the above-described mechanisms in three stages.

  As shown in FIG. 4, the massage machine 1 provided with the rocking part 2 as described above is used for treatment to loosen the joints and muscles of the lumbar part of the user P in a reclining state in which the backrest part 11 is tilted back. It is done. The armrest is not shown. When the user P sits on the massage machine 1 and operates an operation unit (not shown) to select and execute an automatic course programmed with a waist unraveling operation, the control unit 4 controls each part of the massage machine 1. Start control. By the control by the control unit 4, the backrest unit 11 is inclined toward the back of the back, the footrest 13 is raised upward, the entire chair is in a reclining state, and the seat unit 12 is moved from the lateral direction of the massage machine 1. The seat surface is tilted backward as viewed.

  Here, the premise of effective unraveling will be described for unraveling joint and muscle tension due to unraveling motion. The main purpose of unraveling is to acquire the flexibility of the muscles and soft tissues surrounding the joint, and to increase the range of motion of the joint to acquire the range of motion of the normal joint. When performing unraveling exercises aimed at unraveling muscles and improving the range of motion of the joints, etc., the patient should be placed in a comfortable posture, have a stable limb position, and be treated as relaxed as possible. is important. In other words, it is effective to unravel the muscles by first releasing mentally and then letting the user who is in a local or systemic muscular tension state to relax.

  In this regard, the weight of the user is distributed to the backrest 11, the seat 12, and the footrest 13 by maintaining the posture of the user with the massage machine 1 in the reclining state as described above. Thus, the lumbar part to be subjected to the loosening operation can be released from the muscle tension state. That is, according to the massage machine 1 of the present invention, “when the backrest 11 is in the upright position, the waist and thighs support most of the weight of the user, and the waist to be subjected to the unwinding motion is unconscious. It is possible to avoid the state of “being in a muscle tension state” and to perform an effective loosening treatment.

  As described above, in the massage machine 1, after the user is held in a posture suitable for performing a loosening operation on the waist, the swing generation unit 3 incorporated in the base 10 is operated to operate under the waist. The swinging part 2 located in the position starts to operate, and the swinging part 2 imparts local swinging to the lower back part to perform the loosening treatment of the lower back part. The oscillation frequency may be any frequency that allows the joint or muscle to be subjected to the loosening operation to follow the oscillation. However, since the frequency in the vicinity of 4 to 7 Hz is a resonance frequency of the internal organs of the human body, a frequency of 4 Hz or less, preferably a slow frequency of 2 Hz or less is suitable. Further, the method of giving the swinging motion may be a constant frequency from start to finish, or the frequency may be changed with time.

  In addition to the above-described method of giving temporal swing to the waist, various methods as shown in FIGS. 5A to 5D can be used as a method of giving spatial swing. These figures show an example of the movement of the lower back when the user's lower back is viewed from the front. 5 (a) is a vertical swing, FIG. 5 (b) is a horizontal swing, FIG. 5 (c) is a swing with the waist center as a rotation axis, and FIG. 5 (d) is a rotational swing. An example of movement is shown. The types of swinging motions that can be used to loosen the lower back are not limited to the above motions, and a combination of these spatial and temporal motions can be used.

(Second Embodiment)
FIG. 6 shows an outline of the massage machine 1 according to the second embodiment of the present invention. This embodiment is related with the massage machine 1 which uses a wrist joint as a target part of a loosening operation. In this massage machine 1, the armrest 14 in the massage machine 1 (FIG. 1 (a)) of the first embodiment is the swing part 2, and the other points are the massage machine of the first embodiment. Same as 1. The swinging portion 2 at the armrest position is configured such that the wrist joint portion can be naturally weakened by setting the length of the swinging portion 2 to a length that holds the forearm portion excluding the wrist joint. The oscillating unit 2 performs a local oscillating motion that oscillates back and forth in the direction of the arrow in the figure, for example, when the oscillation generating unit 3 incorporated in the base 10 operates. In addition to the front and rear swinging motion, the swinging unit 2 can perform local top and bottom swinging motions or a combined motion thereof.

  When the user P sits on the massage machine 1 and operates an operation unit (not shown) to select and execute an automatic course programmed with wrist joint unraveling operation, the control unit 4 controls each part of the massage machine 1. Start control. Under the control of the control unit 4, the swing generation unit 3 is activated and a swing motion is generated in the swing unit 2. By applying this swinging motion to the arm, a wrist joint loosening effect is obtained.

  In this embodiment, the rocking | swiveling part 2 of an armrest position serves as the role of the attitude | position holding means to hold | maintain the user's P attitude | position. Here, if the length of the swinging portion 2 is a length that holds the entire forearm portion including the wrist joint of the user P, the wrist joint is not in a free state. Even if the swinging portion 2 at the position swings, the wrist joint portion hardly follows the swinging motion of the swinging portion 2, and a desired unraveling effect cannot be obtained. Therefore, the massage machine 1 determines the length of the swing part 2 and the relative positional relationship of the swing part 2 with respect to the backrest part 11 and the seat part 12 according to the physique of the user P, particularly the length of the arm. An adjustment mechanism (not shown) that can be adjusted is provided.

(Third embodiment)
FIG. 7 shows an outline of the massage machine 1 according to the third embodiment of the present invention. This embodiment is related with the massage machine 1 which uses an elbow and a shoulder joint as an object site | part of a loosening operation | movement. This massage machine 1 is such that the height and position of the rocking portion 2 at the armrest position in the massage machine 1 (FIG. 6) of the second embodiment described above can be moved further upward and forward. Other than the difference, it is the same as the massage machine 1 of the second embodiment. Since the swinging part 2 holds the entire hand and arm part at the part ahead of the wrist placed on the swinging part 2, the elbow joint and the shoulder joint are released from the muscle tension state, and the elbow and A loosening effect is obtained on the shoulder joint.

  When the user P sits on the massage machine 1 and operates an operation unit (not shown) to select and execute an automatic course programmed for elbow-shoulder joint loosening operation, the swinging unit 2 at the armrest position is treated. Ascending to a position higher than the shoulder joint of the person P, the swing generation unit 3 built in the base 10 is operated, and the swing unit 2 generates, for example, a local swing motion in the vertical direction. By applying this rocking motion to the elbow and shoulder joint, the effect of loosening the elbow and shoulder joint is obtained. In addition to the up and down swing motion, the swing portion 2 can perform front and rear local swing motion or a combined motion thereof.

  By the way, in general, depending on the degree of muscle tension of the user, physical condition, individual differences, etc., as one of the basic procedures of massage, when viewed locally, the massage target site is directed from the periphery to the trunk It is said that the massage effect can be enhanced by moving in such a manner. Therefore, after performing the wrist joint loosening operation by the massage machine 1 in the second embodiment described above, the position and height of the rocking part 2 are moved, and the elbow and the massage machine 1 in the third embodiment are moved. If the shoulder joint is loosened, the target part of the loosening motion is directed from the periphery to the trunk, so that the effect can be further enhanced.

(Fourth embodiment)
FIG. 8 shows an outline of the massage machine 1 according to the fourth embodiment of the present invention. This embodiment relates to a massage machine 1 of another example in which an elbow and a shoulder joint are loosened and used as a target site for movement. In this massage machine 1, the armrest 14 in the massage machine 1 (FIG. 1 (a)) of the first embodiment is the swing part 2, and the other points are the massage machine of the first embodiment. Same as 1. The swing part 2 at the armrest position rotates and swings in a horizontal plane when the swing generation part 3 built in the base 10 is operated. When the user puts his arm on the swinging portion 2, the elbow and shoulder joint connected to the arm perform a passive swinging motion in conjunction with the swinging motion of the swinging portion 2, whereby the elbow and The effect of loosening the shoulder joint is obtained.

  The swinging motion of the swinging unit 2 described above may be performed with a constant amplitude from start to finish, or the amplitude may be changed. For example, when the amplitude of the swing motion is small, the swing motion of the elbow and shoulder joints is also small and a sufficient unraveling effect cannot be obtained. Therefore, it is preferable to increase the amplitude gradually from a swinging motion with a small amplitude at the beginning, in order to obtain a sufficient unraveling effect and to prevent an unexpected injury. In addition, since the movable range of the joint varies depending on the person to be treated, it is preferable that the upper limit of the swing motion amplitude can be adjusted separately.

(Fifth embodiment)
FIG. 9 shows a rocking mechanism of the footrest of the massage machine 1 according to the fifth embodiment of the present invention. This embodiment is related with the massage machine 1 which makes a foot | leg part an object site | part of operation | movement. In this massage machine 1, the footrest 13 of the massage machine 1 in each of the above-described embodiments constitutes the swing part 2, and the other points are the same as those of the respective embodiments. Therefore, in the following, for example, FIG. 6 is referred to in addition to FIG. The rocking generator 3 of the massage machine 1 is provided inside the base 10, and includes a screw shaft 16, a nut 17 screwed onto the screw shaft 16, a motor (not shown) that rotates the nut 17, and The link member 18 is provided between the nut 17 and the swinging portion 2 and transmits the movement of the nut 17 to the swinging portion 2.

  The swinging part 2 is pivotally fixed to a hinge part 19 provided at the upper front part of the base 10 at the upper end part thereof, and the nut 17 is moved forward and backward by a forward / reverse operation of a motor (not shown). Oscillating motion consisting of rotation about the hinge portion 19 is performed. The movements of the swing generation unit 3 and the swing unit 2 are not limited to the mechanism shown in FIG. 9 and the movements thereof. For example, the swing generation unit 3 and the swing unit 2 swing horizontally or the massage machine 1 faces the front. As seen, the swinging portion 2 formed of the footrest 13 may be of a mechanism that generates swinging such that the swinging portion 2 swings in the shape of a figure 8.

  When the user sits on the massage machine 1 and operates the operation unit to execute the automatic course programmed with the foot unraveling operation, the control unit 4 starts controlling each part of the massage machine 1. Under the control of the control unit 4, the footrest 13 (swinging unit 2) is rotated upward until it reaches a predetermined stretch position, and then the swinging unit 2 swings at a predetermined speed and centering around the hinge unit 19. Repeated reciprocating rotation with dynamic amplitude. The foot of the user is loosened while being protruded from the tip of the swinging portion 2 (below), and the swinging motion of the swinging portion 2 loosens the ankle joint in a weak state. An effect is obtained. In this embodiment, the footrest 13 serves as both the posture holding means for holding the posture of the user and the swinging unit 2.

  Here, if the length of the swinging portion 2 is longer than the length from the knee joint to the ankle joint of the user, the ankle joint is placed on the footrest 13, and the swinging portion 2. Even if the reciprocating rotation is performed, the ankle joint part is less likely to swing following the reciprocating rotation of the swinging portion 2, and a desired unraveling effect cannot be obtained. In order to avoid such a problem, an adjustment mechanism that can adjust the length of the swinging portion 2 can be provided.

  The massage machine 1 of each embodiment described above performs a loosening operation in accordance with the target part of the unraveling operation while maintaining an optimal posture for the target part to be released from the muscle tension state. Therefore, it is possible to enhance the effect of unraveling compared to the case of performing the unraveling operation in a muscle tension state. More preferably, a predetermined massaging operation that massages each part of the body of the user by a kneading motion of a function (massaging function) that performs a normal kneading motion other than a loosening motion by the rocking motion of the rocking portion 2 is performed, After guiding to the relaxed state, as described above, if the posture corresponding to the target part is held and the loosening operation by the swinging unit 2 is executed, the effect can be further enhanced.

  In each of the above-described embodiments, like the waist portion in the first embodiment, the wrist joint in the second embodiment, the elbow shoulder joint in the third and fourth embodiments, and the ankle joint in the fifth embodiment. In the above description, the unraveling operation for each treatment target part is performed individually. However, the unraveling operations for a plurality of parts may be performed in parallel or sequentially. Further, the swinging means (the swing generating part 3 and the swinging part 2) are not limited to those of the above-described embodiment, and for example, use a repetitive operation by inflation and contraction of an airbag. May be.

  In addition, when the lower back portion is to be subjected to a loosening operation, the fir ball used for conventional normal massage provided on the backrest portion 11 can be used as the swinging portion 2. In this case, after lowering the kneading balls to the lower back, the kneading balls are intermittently protruded toward the user's lower back, or the kneading of the lower back by the kneading balls (squeezing by the left and right kneading balls) You may give a local rocking | fluctuation to a waist | hip | lumbar part.

  Further, the direction of swinging is not limited to the direction of swinging in each of the above-described embodiments, but the top and bottom, left and right, front and rear directions, and directions that combine these directions in terms of space and time. be able to. Therefore, the three-dimensional swinging and rotating motion by the swinging unit 2 can be loosened. For example, the swinging amplitude of the swinging part 2 can be gradually increased or gradually decreased with time. Further, the position of the oscillating unit 2 can be made variable, and the position of the oscillating unit 2 can be gradually raised or lowered over time.

  Furthermore, the swinging part 2 and the posture holding means can be combined. In addition, the reclining angles of the backrest part 11, the seat part 12, and the footrest 13 for maintaining the posture of the user are not limited to the above-described embodiment, and the target part of the unwinding action is muscle tension.
