DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair-type massage machine which can massage not only the back but also the lower body.

[0002]

2. Description of the Related Art As a chair type massage machine, Japanese Patent Publication No. Sho 6
There are those disclosed in JP-A-3-52902 and JP-A-4-138158. Each of these is provided with a massage mechanism on both the backrest portion and the footrest portion, and is configured to be able to massage the back and the calf of the foot. In this case, as the massage mechanism, a roller-type massage mechanism is adopted for the backrest,
A roller type or vibration type massage mechanism is adopted as the massage mechanism of the foot rest.

[0003] Here, the roller-type massage mechanism of the backrest portion adopts a structure in which the massage roller is moved up and down while rotating the massage roller to massage the entire back, and the roller-type massage mechanism of the footrest portion is provided at the peripheral portion. By rotating a rotating body provided with a plurality of massage rollers, the massage roller is intermittently applied so as to be rubbed on the calf of the foot and massaged.

[0004] The vibration massaging mechanism of the footrest is configured to massage a calf of a foot by generating vibration by rotating a rotating body having an eccentric weight.

[0005]

As described above, the conventional chair type massage machine mainly massages a part of the lower body such as the upper body (back) and the calf of the foot, and includes the entire lower body. It does not have the function of massaging the whole body. In particular, the method of giving a massage to a calf by massaging it has a weak massage power and is inferior to a treatment feeling.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to massage not only the upper body but also substantially the entire lower body, and to obtain a good treatment feeling for the lower body. To provide a chair-type massage machine that can do.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention comprises a seat portion for receiving the buttocks and feet, and a back portion for receiving the back, and the back portion is subjected to a massage operation such as hitting or massaging. In the chair-type massage machine provided with a treatment element for performing the treatment, a foot receiving member for receiving both feet at the ankle side than the knee is provided on the seat portion so as to be movable in the left-right direction, and this foot receiving member is reciprocated right and left by the driving device. It is characterized by being configured to be moved.

[0008] According to this means, for example, a portion near the ankle of both feet is placed on the foot receiving member, and the foot receiving member is reciprocated right and left. Then, since the hips are placed on the seat and leaning on the backrest, the waist part hardly moves, and the ankle parts of both feet are reciprocated in the left and right direction, so the left and right feet are twisted Then, the part below the waist swings right and left around the waist. For this reason, almost the entire lower body is subjected to a massage action by twisting, whereby blood circulation of the lower body is improved, and a refreshing massage feeling is obtained.

The seat portion comprises a seat portion and a footrest portion, a footrest member is provided on the footrest portion, and the front end portion of the footrest portion is raised from a downward position in which the front end side is lower than horizontal. The angle can be adjusted up to the upward posture.

In this way, when the angle of the footrest is adjusted, for example, the height of the ankle portion received by the footrest member changes, so that particularly from the relaxed state in which the rear side of the knee is not very tense. You can receive massages in various conditions, until the back of your knees are very tense.

In the present invention, the treatment element of the backrest portion may be constituted by at least a pair of right and left eccentric rollers reciprocable in a direction along the back, and the pair of eccentric rollers may be provided eccentric in opposite directions. When such an eccentric roller is provided, the pair of left and right eccentric rollers rotate, so that the pair of eccentric rollers alternately push up the back. For this reason, the upper body can be twisted left and right around the spine, so that the upper body can also receive the twist massage together with the lower body that receives the twist massage by the reciprocating movement of the foot receiving member.

In this case, a plurality of pairs of left and right rollers are provided on both sides of the pair of eccentric rollers in the reciprocating direction, and two sets of left and right eccentric rollers are disposed on both sides in the reciprocating direction along with the rotation. Of the outer peripheral surfaces of the pair of rollers, it can be configured so as to protrude and retract with respect to a straight line that is commonly in contact with the outer peripheral surface on the front side of the backrest.

According to this, it is possible to prevent the large upper body from swaying right and left such as swaying right and left up to the head. When one pair of eccentric rollers protrudes to push the back forward, the other retreats away from the back, so the upper body swings greatly left and right, and the head also swings right and left with this Although the user may feel uncomfortable, since the back is received by the rollers provided on both sides of the eccentric roller, it is possible to prevent the large upper body from swinging left and right such as swinging right and left up to the head.

Further, when the pair of eccentric rollers and the foot receiving portion operate, when the left eccentric roller rotates so as to protrude toward the surface of the backrest, the foot receiving portion moves to the left and the right eccentric roller moves to the right. When the eccentric roller rotates so as to protrude toward the front side of the backrest, the foot support may be configured to move rightward. By doing so, the twisting direction of the lower body and the twisting direction of the upper body are reversed, so that the twisting of the whole body is increased and massage can be performed more effectively.

[0015]

The sixth link 57 is rotatably connected to the footrest 5 together with the fifth link 56. The first link 52 to the sixth link thus connected.
The link mechanism including the link 57 constitutes a push-up mechanism 58. When the operation shaft 50 is rotated in the direction of arrow B, the first link 52 to the sixth link 57 are moved from the reduced state shown in FIG. The state changes to the expanded state shown in FIG. 6 through the middle expanded state shown in FIG.

In the contracted state shown in FIG. 8, the footrest 5 is in a posture in which the front end side is lower than horizontal, for example, a hanging posture in which it is substantially vertical downward. This hanging posture,
This is a state in which the foot rest 5 is not used. In the middle extension state of FIG. 7, the footrest unit 5 is in a substantially horizontal posture.

In the extended state shown in FIG. 6, the foot rest 5 is in an upward position in which the front end is higher than horizontal, and the sole can be rested on the foot rest 5 without forcibly extending the ankle. Becomes At this time, from the hanging state in FIG. 8 to the upward posture in FIG. 6, the push-up mechanism 58 pushes up the footrest 5 so as to gradually move forward from the seat 4. Since the seat portion 4 is continuous with the cushion body 14 and the outer material 18 of the footrest portion 5, even when the footrest portion 5 is separated from the seat portion 4, no gap is formed therebetween.

As described above, the angle of the footrest 5 can be adjusted from the hanging posture to the upward posture, but in this embodiment, the footrest 5 is in the hanging posture, the horizontal posture, and the horizontal posture.
The three postures of the upward posture can be maintained. The hanging posture is not particularly locked because the weight of the foot rest 5 acts to contract the first link 52 to the sixth link 57 of the lifting mechanism 58.

The horizontal posture is maintained by locking the operation shaft 50 by inserting the lock pin 60 provided on the operation shaft 50 into the lock groove 59a of the lock member 59 fixed to the column 9. As shown in FIG. 9, the lock pin 60 is supported by a grip 51 of the operation shaft 50 so as to be vertically movable.
It is urged upward by a compression coil spring 61. When the operation shaft 50 is rotated so that the foot rest 5 is in the horizontal position, the lock pin 60 rides on the inclined surfaces 59b on both sides of the lock member 59, and the foot rest 5 is in the horizontal position. At this point, the lock pin 60 is
The spring force fits into the lock groove 59a. In order to release the horizontal position lock of the foot rest 5, the lock pin 60 may be depressed by the push button 62 and removed from the lock groove 59 a.

The holding of the upward posture is performed by the second link 5.
This is performed by a stopper 63 bent below the distal end portion 3. When the foot rest 5 is in the upward posture, the connecting portion between the first link 52 and the third link 54 is upwardly “k”.
The push-up mechanism 58 is locked in the extended state by the stopper 63 provided below the distal end portion of the second link 53 abutting on the third link 54 because of the bent state. The placing section 5 is held in an upward posture.

In the seat part 6 on which the lower body is placed, the foot rest part 5 on which the part below the knee is placed is provided with a swinging massage mechanism 64 for massaging the lower body as shown in FIG. Have been. The oscillating massage mechanism 64 reciprocates a foot receiving member 65 that receives, for example, an ankle portion of both feet in the left-right direction by a driving device 66,
This is for shaking both legs left and right to massage the lower body.

3 to 5, a mounting plate 67 having a substantially U-shaped cross section is mounted on the footrest frame 20 in FIGS. Two upper and lower guide rods 68 are attached inside 67. The slider 69 is supported by the guide bar 68 so as to be slidable in the left-right direction.

The mounting plate 67 is provided with a motor 70 as a drive source. The rotating shaft 70a of the motor 70
Protrudes inside the mounting plate 67, and its rotating shaft 70
A crank 71 is attached to the tip end of a. A vertical groove 72 is formed in the slider 69, and a crank pin 71a of the crank 71 is inserted into the vertical groove 72. As described above, the driving device 66 for reciprocating the foot receiving member 65 left and right is configured.

On the other hand, the foot receiving member 65 is made of plastic, and has two substantially semicircular recesses 73 formed on the upper surface for receiving the ankle portions of both feet. A fitting cylindrical portion 74 as a portion protrudes.
Thus, the cloth 75 for softening the feel is attached to the surface of the foot receiving member 65.

A laterally long insertion hole 76 is formed in the outer material 23 and the cushion body 15 of the footrest 5 so that the upper end portion of the slider 69 can move left and right in the insertion hole 76. It is located with a gap on the left and right. Then, the fitting cylindrical portion 74 of the foot receiving member 65 is inserted into the insertion hole 7.
The foot receiving member 65 is detachably attached to the slider 69 by being fitted into the upper end of the slider 69 so as to be inserted into the slider 6.

In order to remove the foot receiving member 65, it is sufficient to pull it up and remove the fitting cylinder 74 from the slider 69. When the foot receiving member 65 is detached from the slider 69, the foot rest 5 has no protrusion on its upper surface. For this reason, when used as a chair, there is no possibility that a problem such as a protruding object touching the body and causing discomfort may be caused.

As described above, the massage machine of the present embodiment includes the roller-type massage mechanism 25 and the oscillating-type massage mechanism 64.
Reference numeral 64 is controlled by a control device (not shown) according to the operation contents of a remote control box (hereinafter, remote control) 77 shown in FIG.

The remote controller 77 includes a switch 77a for selecting a whole body course, an upper body course, and a leg swing course.
When the whole body course is selected, both the roller massage mechanism 25 and the oscillating massage mechanism 64 perform a massage operation in a predetermined mode for a predetermined time to massage the whole body. When the upper body course or the leg swing course is selected, the roller-type massage mechanism 25 is selected.
Alternatively, only the oscillating massage mechanism 64 performs the massage operation.

When massaging by the roller-type massaging mechanism 25, the rollers 41, 42 and 45 reciprocate up and down along the back. At this time, when the shoulder positioning switch 77d is operated, the shoulder position adjusting switch 77d is operated in accordance with the height of the user. It is possible to adjust the position where the movement from the upward movement to the downward movement is made. The pair of left and right rollers 41, 42, 45
Move along the left and right sides of the spine.

When the hitting / fir selection switch 77e is operated, the rotation speed of the eccentric roller drive motor 46 changes in height, and the eccentric roller 45 makes a quick circular motion at the high speed rotation and hits the back. Eccentric roller 4
5 slowly moves in a circular motion and begins to lean on his back.

Further, on the favorite course, the back streak roller switch 77f is operated to reciprocate the roller-type massage mechanism 25 up and down to massage the entire back. You can choose either to stop and massage. At this time, the vertical adjustment switch 77g, 7
By operating 7h, the range of reciprocation of the roller-type massage mechanism 25 can be changed, and the stop position can be adjusted.

By operating the leg swing switch 77i of the favorite course, the swingable massage mechanism 64 can be operated for a desired time. In addition, when the whole body course, the leg swing course is selected, and when the leg swing is selected in the favorite course, when the speed adjustment switches 77j and 77k are operated, the rotation speed of the motor 70 is changed to reciprocate the foot receiving member 65. You can change the speed.

When the motor 70 is started,
The speed control is performed so that the rotation speed gradually increases until the rotation speed reaches the set rotation speed, and the speed control is performed such that the rotation speed gradually decreases even when the rotation is stopped until the rotation speed becomes zero. When the storage switch 70m is operated, the roller-type massage mechanism 25 (moving base frame 29)
Is configured to move to a lowermost position below the seat portion 4 and stop there.

Next, the operation of the above configuration will be described assuming that the whole body course is selected. First, the operating shaft 50 is rotated in the direction of arrow B to bring the push-up mechanism 58 into the extended state, the footrest 5 is set to the horizontal posture or the upward posture, and the foot receiving member 65 is fitted to the slider 69. connect. When the angle of the footrest 5 is adjusted, the push-up mechanism 58 initially rotates the footrest 5 upward and then pushes it forward, so that the footrest can be moved between the horizontal posture and the upward posture. The position of the member 65 is different between the front and the rear. Therefore, by selecting the posture of the foot rest 5 in accordance with the height of the user, the foot receiving member 65 can be set at a position suitable for extension.

Thereafter, the user sits down on the seat 4 and lowers the backrest 7 to the desired reclining position, and places the ankles of both feet in the recesses 74, 7 of the foot receiving member 65.
4 and hold it. In this state, the buttocks of the user are received by the seat portion 4, the back is received by the backrest portion 7, and the feet are received by the foot receiving members 65 and are in a state of being suspended in the air. For this reason, the knee is extended, and when the footrest 5 is in the horizontal position, the degree of tension on the back side of the knee is relatively weak, the posture is relaxed, and the footrest 5 is in the upward position. In this case, the back side of the knee is stretched strongly, resulting in a tense posture.

When the whole body course is selected by the remote controller 77, the roller-type massage mechanism 25 and the oscillating-type massage mechanism 64 perform a massage operation. First, the operation of the roller-type massage mechanism 25 will be described. When the whole body course starts, the motor 34 for vertical movement and the eccentric roller drive motor 46 are energized. And the motor 34
The moving base frame 29 reciprocates in the vertical direction by the forward and reverse rotation of.

By the reciprocating movement of the moving base frame 29, FIG.
As indicated by a two-dot chain line in FIG.
2 comes into contact with the left and right sides of the spine via the outer material 24 of the backrest 7 and moves while rotating. As a result, the entire back is massaged from the shoulder. At this time, since the eccentric shaft 44 is rotated by the motor 46, the central eccentric roller 45 intermittently hits the shoulder and the back, thereby simultaneously performing a massage such as beating or firs.

When the moving base frame 29 moves as described above, the roller support 36 is pivotally supported by a swing shaft 37, and the roller support 36 is provided with a swing shaft 37. Rollers 41 and 42 are located on the upper and lower sides of the
Is provided, the rollers 41 and 42 move to follow the unevenness of the back with the swing of the roller support base 36. For this reason, both rollers 41, 4
2 comes in contact with the back and moves while exerting a massage action.

In contrast to the upper and lower rollers 41 and 42, which always move in contact with the back, the eccentric roller 45 located in the middle of the upper and lower rollers 41 and 42 has the outer peripheral surface of the backrest 7 on the outer peripheral surface of the rollers 41 and 42. Since the eccentric roller 45 rotates and comes into contact with the back intermittently, the eccentric roller 45 comes into contact with the back intermittently, so that a good massage effect by hitting can be obtained.

The upper body is shaken so as to be twisted right and left by the alternating massage action of the pair of left and right eccentric rollers 45, so that the upper body receives the massage action by twisting. Moreover, since the pair of left and right eccentric rollers 45 alternately hit the back in this way to obtain a massage effect, the upper and lower sides of the part to be beaten or rubbed are supported by the rollers 41 and 42. The body does not sway left and right as much as the head shakes with the rotational movement of the eccentric roller 45. Even if the body sways, the sway is small, and the feeling of discomfort is reduced.

The upper and lower rollers 41, 42
As the upper body is hit by the middle eccentric roller 45 while receiving the weight of the upper body, the weight of the upper body does not directly act on the eccentric roller 45.
For this reason, the motor 46 does not receive a large resistance,
The eccentric roller 45 can be smoothly rotated, and the intermittent tapping massage action by the eccentric roller 45 can be effectively given.

Further, since the roller type support base 36 is urged to rotate in the direction of arrow A by the torsion coil spring 38, when the upper roller 42 comes to a position to massage the shoulder, the roller support base 36 is rotated. Is a torsion coil spring 38
Since the roller 42 swings in the direction of arrow A due to the resilience of the roller 42 and hits the base of the neck, the eccentric roller 45 hits the shoulder, so that the eccentric roller 45 can satisfactorily hit or knead the shoulder. .

On the other hand, in the oscillating massage mechanism 64, when the massage by the whole body course is started, the motor 70 is started, and the rotation speed is gradually increased to the target speed. The rotation of the motor 70 is converted into a reciprocating movement of the slider 69 by the crank 71, and the foot receiving member 65 reciprocates right and left. At this time, the reciprocating movement speed of the foot receiving member 65 does not suddenly increase to the target speed but gradually increases, so that there is no possibility that the foot falls off the concave portion 74 of the foot receiving member 65.

When the foot receiving member 65 reciprocates in the left-right direction, the lower body swings left and right (so-called goldfish movement) around the waist portion supported by the seat portion 4 and each of the left and right legs. F1 and F2 are twisted around the base of the foot as shown by the solid line, the two-dot chain line and the broken line in FIG. For this reason, a twisting motion is also given to the waist portion.

At this time, when the left eccentric roller 45 of the pair of eccentric rollers 45 of the roller type massage mechanism 25 is rotated so as to project toward the surface of the backrest 7, the foot receiving portion 65 moves to the left. When the right eccentric roller 45 rotates so as to protrude toward the surface of the backrest 7, the foot receiving portion 65 moves rightward.

As described above, the eccentric roller 45 and the foot receiving portion 65
When the upper body is twisted rightward, the lower body is twisted leftward, and conversely, when the upper body is twisted leftward, the lower body is twisted rightward. For this reason, the twisting directions of the upper body and the lower body are reversed, and the body is greatly twisted when viewed from the whole body, so that a more effective massage can be received.

As described above, since the lower body as a whole repeatedly exercises such as rolling and twisting while changing its direction from side to side, the muscles of the lower body are rubbed and loosened, and blood circulation is improved. . The lower body is subjected to such a massage action, and the intensity of the massage is not weak as in the case of the vibration type massage, so that the lower body has a moderate strength for the massage. When the speed adjustment switches 79j and 79k are operated during such lower body massage, the foot receiving member 65 is operated.
Because the reciprocating speed of the body changes, you can receive a massage at your preferred speed.

At the end of the whole-body course, the rotation speed of the motor 70 is gradually reduced until it stops. For this reason, also at the time of stop, the reciprocating movement speed of the foot receiving member 65 gradually decreases, so that there is no possibility that the foot will fall off the concave portion 74 of the foot receiving member 65 at the start.

After the massage operation is completed, if the foot receiving member 65 is detached from the slider 69, the surface of the foot rest 5 has no protruding material. No discomfort such as hitting the feet.

According to the fifth aspect of the present invention, large swinging of the upper body, which swings right and left up to the head, can be prevented by the rollers provided on the upper and lower sides of the eccentric roller.

According to the sixth aspect of the present invention, since the twisting direction of the lower body and the twisting direction of the upper body are reversed, the twist of the whole body is increased, and massage can be performed more effectively. According to the seventh aspect of the present invention, the intensity of the massage can be changed as desired by changing the speed of the foot receiving member. According to the invention described in claim 8, at the time of starting and ending the massage operation, the reciprocating speed of the foot receiving member gradually changes, so that there is no possibility that the foot comes off the foot receiving member.

According to the ninth aspect of the invention, by adjusting the position of the foot receiving member in the front-rear direction, the foot can be placed on the foot receiving member at a desired position. According to the tenth aspect of the present invention, since the foot receiving member can be removed, the foot receiving member does not interfere when the lower body is not massaged or when used as a chair. According to the eleventh aspect of the present invention, when the foot receiving member is removed, the surface of the seat portion is in a state where there is no protrusion, so that it is possible to sit comfortably.
