Patent document 1: japanese patent laid-open publication No. 2017-143988

Disclosure of Invention

The massage machine disclosed in patent document 1 massages the body part (sole) of the person to be treated by rotating the rollers, but since the rollers are fixed, the body part (sole) cannot be massaged in a wide range, and there is a problem that the same part is subjected to treatment and the stimulation is monotonous. The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a massage machine that can massage a wide range of body parts of a person to be treated and can apply complicated stimulation.

The invention is a massage machine, characterized by comprising: a body support portion that supports an upper limb or a lower limb of a person to be treated, the body support portion having a treatment tool protruding in a direction substantially orthogonal to a back surface or a lower surface of a body supported by the body support portion; an arm portion supporting the treatment member; a drive unit that drives the treatment member via the arm portion in a direction substantially parallel to the back surface or the lower surface of the body, the drive unit including: a motor; an eccentric portion that causes the arm portion to be eccentric with respect to the center of the rotation shaft of the motor; and a restricting member that restricts the movement of the arm portion so that the treatment member describes an elliptical orbit. With such a configuration, the back or lower surface of the body can be massaged over a wide range with respect to the upper limbs or the lower limbs.

Further, the following is preferable: the arm portion has a swing shaft that supports the arm portion so as to be capable of swinging in a direction substantially orthogonal to the back surface or the lower surface of the body.

With this configuration, the arm portion can be swung to change the stimulation to the treatment site.

Further, the following is preferable: comprising: a push-up member that pushes the treatment member in a direction close to the back or lower surface of the body; and a control unit that controls the drive unit and the push-up member.

With this configuration, the treatment member can be pressed against the back surface or the lower surface of the body, and thus a stronger stimulation can be given to the person to be treated.

Further, the following is preferable: the body support portion has an accommodation portion capable of accommodating the treatment member, and the control portion controls the push-up member so that the treatment member is accommodated in the accommodation portion so as not to protrude from a surface of the body supporting the body support portion when treatment is not performed.

With this configuration, the treatment implement does not contact the body when treatment is not performed, and thus the user does not feel troublesome.

Further, the following is preferable: the body support portion has a side wall portion, and the drive portion is provided in the side wall portion.

With this configuration, the driving portion can be prevented from being hindered.

The following are preferred: the body support portion further includes a pressing portion that presses the upper limb or the lower limb of the person to be treated from above or from the side, the massage machine includes a connecting portion that follows the movement of the treatment member by the driving portion, and the pressing portion is provided on the connecting portion.

With this configuration, the upper or lower limbs of the person to be treated are pressed from above or from the side following the pressing portion of the treatment tool, and thus the treatment site can be prevented from escaping by the treatment from the back or lower surface of the body, and the stimulation to the treatment site becomes stronger.

Further, the following is preferable: the push-up member has a protrusion portion having a surface inclined in a direction of contacting the treatment member.

With this configuration, the treatment member is pushed up along the inclined surface of the protrusion, and stimulation can be applied along the shape of the body. For example, the stimulation can be applied along the arch of the foot as long as the sole is the sole.

Further, the following is preferable: the body support portion has a grasping member capable of grasping the upper or lower limb of the person to be treated provided on the side wall portion from the side or from above, and the treatment is performed by the treatment tool in a state where the upper or lower limb of the person to be treated is grasped.

With this configuration, the upper or lower limbs of the person to be treated can be held from the side or from above, and thus the upper or lower limbs can be prevented from moving by the treatment from the back or lower surface of the body, and the person to be treated can be massaged more appropriately.

Further, the following is preferable: the body support part has an ejection member which supports the feet of the person to be treated and can eject the feet of the person to be treated from the rear to the tiptoe direction, the ejection amount ejected by the ejection member can be adjusted, and the treatment is performed by the treatment member in the state of being ejected by the ejection member.

With this configuration, treatment can be performed according to the size of the foot of the user.

Further, the following is preferable: the massage machine includes a push-up member configured to push the treatment tool in a direction approaching a back surface or a lower surface of the body, the body support portion includes a side wall portion, the body support portion includes a holding member configured to hold an upper limb or a lower limb of the person to be treated provided on the side wall portion from a side or an upper side, the body support portion includes a push-out member configured to support a foot of the person to be treated and to push out the foot of the person to be treated in a toe direction from a rear side, and at least one of the push-up member, the holding member, and the push-out member is configured by an airbag.

With such a configuration, the upward pushing, the clamping, and the pushing out can be performed by the expansion and contraction of the airbag, and therefore, the operation can be performed with a simple configuration.

The treatment tools 62 (see fig. 5) of the massage unit 8 protrude forward from the opening 3b, and can massage the trunk of the person to be treated from behind via the cover member 3 c.

[ Structure of massage Unit ]

The structure of the massage unit 8 will be described below.

As shown in fig. 1 to 3 and 5, the backrest 3 is provided with a massage unit 8 for massaging the upper body of the user from the rear (back). The massage unit 8 may be provided in plural numbers (1 in the present embodiment) in the height direction. The massage unit 8 is composed of a pair of right and left arms 61 and treatment tools 62 provided at both upper and lower ends of the arms 61, and can perform a kneading massage in which the right and left treatment tools 62 come close to or separate from each other and a tapping massage in which the right and left treatment tools 62 alternately move back toward the person to be treated by driving the massage motors M1 and M2.

The massage unit 8 is driven by the elevating motor M3 to move upward or downward in the height direction, thereby changing the position relative to the body or performing a rolling massage. The back frame 3a is provided with a pair of right and left guide rails 18 extending in the height direction, and the massage unit 8 moves along the guide rails 18. The massage unit 8 is movable in the height direction, and thus the neck to waist of the person to be treated can be massaged by the treatment tools 62.

As shown in fig. 5, the massage unit 8 includes a base frame 60a and a movable frame 60b supported by the base frame 60 a. The base frame 60a has guide wheels 63 fitted to the guide rails 18 on both left and right sides thereof. The height direction can be moved by an elevating mechanism (not shown) including a rack and pinion. The movable frame 60b is supported by the base frame 60a via a swing shaft 64 in the left-right direction. Between the base frame 60a and the movable frame 60b, a forward/backward driving unit 65 formed of an airbag or the like is provided. The movable frame 60b can be advanced and retracted in the front-rear direction about the swing shaft 64 by the driving of the advance and retraction driving unit 65. Further, instead of advancing and retracting the movable frame 60b, only the arm 61 may be advanced and retracted by providing the arm 61 with the advance and retraction driving portion 65.

The arm 61 is connected to a kneading shaft 66 and a tapping shaft 67 extending in the left-right direction. Inclined cams 66a having inclined shaft portions 66b are provided on both right and left sides of the kneading shaft 66, and the arm 61 is attached to the inclined cams 66 a. The left and right inclined shaft portions 66b are inclined with respect to the axial center of the kneading shaft 66 so as to form a substantially splayed shape in front view. Eccentric cams 67a having eccentric shaft portions 67b eccentric with respect to the axial center of the striking shaft 67 are provided on both right and left sides of the striking shaft 67, and the arm 61 is attached to the eccentric cams 67a via a connecting rod 68. The left and right eccentric shaft portions 67b are different in phase from each other, specifically, by 180 degrees, with respect to the axial center of the striking shaft 67. The kneading shaft 66 and the tapping shaft 67 are rotated by driving the massage motors M1 and M2, respectively. The treatment members 62 perform a kneading massage by rotation of the kneading shaft 66, and a tapping massage by rotation of the tapping shaft 67. The arm 61, the kneading shaft 66, and the beating shaft 67, on which the treatment tools 62 are provided, are supported by the movable frame 60 b. Therefore, the treatment tool 62 can be advanced and retreated relative to the user by moving through the movable frame 60 b.

The arm 61 is swingable in the front-rear direction, and is biased by a biasing member (not shown) such as a spring so that the upper treatment tool 62 protrudes forward. The massage unit 8 also has a sensor 69 for detecting body information of the person to be treated. The sensor 69 can obtain body information by detecting that the arm 61 has reached a predetermined swing position. Specifically, when the upper treatment tools 62 reach above the shoulders while the massage unit 8 is being raised in the height direction, the load on the treatment tools 62 is released, and the arm 61 swings forward to a predetermined swing position. The sensor 69 detects that the arm 61 has reached a predetermined swing position, and detects the position of the shoulder from the vertical position of the massage unit 8 at that time. The positions of other parts (neck, back, waist, etc.) are calculated based on the positions of the shoulders. The detected body information is stored in the storage unit 50.

As shown in fig. 11 to 16, the massage unit 70 provided in the foot support portion 41 includes treatment members 71 for treating the lower surface of the body of the user (in this case, the sole), and the treatment members 71 are shaped to protrude in a direction substantially perpendicular to the lower surface of the body of the user. The treatment tool 71 is supported by the arm portion 72, and the arm portion 72 is coupled to the driving portion 73 provided in the side wall 41b via the coupling portion 82. The driving unit 73 is a motor 74, and includes an eccentric portion 75 eccentric with respect to the center of the rotation shaft of the motor 74, and a regulating member 76 for regulating the movement of the arm portion 72. The eccentric portion 75 includes an eccentric cam 75a and a bearing 75b, and the coupling portion 82 is coupled to the eccentric cam 75a via the bearing 75 b. The treatment implement 71 supported by the arm portion 72 driven by the driving portion 73 is moved so as to describe an elliptical orbit by the regulating member 76.

As shown in fig. 11 to 13, the bottom wall 41a includes: a front side support portion 41e for supporting the tiptoe side of the foot of the person to be treated; a rear support portion 41f for supporting the heel side of the foot of the patient; and an accommodating portion 77 capable of accommodating the arm portion 72 and the treatment member 71. The front support 41e and the rear support 41f are provided with massage portions a7, respectively. The accommodating portion 77 is a recess formed between the front support portion 41e and the rear support portion 41 f. That is, the foot of the person to be treated is supported by the lower surface of the body on the toe side and the heel side, and the arch of the foot floats above the concave portion. As shown in fig. 14 and 16, the arm portion 72 has a swing shaft 79 and is supported so as to be swingable in a direction substantially orthogonal to the lower surface of the body of the treatment subject. The accommodating portion 77 is provided with a push-up member 78, and the treatment members 71 can be brought close to the lower surface of the body of the treatment subject by pushing up the arm portions 72 with the push-up member 78. When treatment is performed, treatment is performed by pushing up the treatment device 71 by the push-up member 78, and when treatment is not performed, the treatment device 71 is accommodated in the accommodating portion 77 so as not to protrude from the body surface supporting the front support portion 41e and the rear support portion 41f, because the push-up member 78 does not push up. Thus, the user can press the lower surface of the body of the user with his/her fingers during treatment, and when treatment is not performed, the user can be prevented from further pressing the lower surface of the body of the user even when the treatment tool 71 is not performing treatment. When the treatment tool 71 is moved to a desired treatment start position, the treatment tool can be moved while reducing or eliminating resistance applied from the lower surface of the body of the user. The massage portion a7 and the push-up member 78 are constituted by the air bag 20 that expands and contracts by the supply and discharge of air. Instead of the airbag 20, a mechanical push-up mechanism may be used.

The push-up member 78 has a protrusion 80 in a direction facing the treatment member 71. The treatment member 71 of the protrusion 80 has a surface inclined in a direction of contact, specifically, along the shape of the arch of the foot. By this inclination, the stimulus given to the lower surface of the body of the treatment subject by the treatment member 71 can be changed. When the foot is treated, the treatment tool 71 is moved along the inclined surface, thereby performing treatment along the arch of the foot of the person to be treated. When the push-up member 78 is constituted by the airbag 20, the protrusion 80 may be provided on the airbag 20, or may be inflated so that the airbag 20 itself has an inclined surface.

The foot support portion 41 has a pressing portion 81 for pressing the foot of the person to be treated from above or from the side. The pressing part 81 is connected to the driving part 73 by a connecting part 82 that tracks the movement of the treatment applying member 71 by the driving part 73. Specifically, the driving portion 73 is provided with coupling portions 82 at upper and lower sides thereof, the pressing portion 81 is provided at the upper coupling portion 82, and the arm portion 72 is provided at the lower coupling portion 82. Since the restriction members 76 are provided in the upper and lower connecting portions 82, respectively, and the restriction members 76 are connected by the connecting shaft 85, the upper and lower portions draw the same trajectory. The pressing part 81 can follow the movement of the treatment tool 71 by the upper and lower connecting parts 82.

By pressing the pressing portion 81, the pushing-up member 78 pushes up the treatment member 71 to treat the lower surface of the body of the patient, so that the treatment site can be prevented from being lifted up and the force can be prevented from being lost, and the treatment member 71 can be pressed, whereby the treatment feeling can be further enhanced. The pressing portion 81 is constituted by the airbag 20 that is inflated and deflated by the supply and discharge of air. The amount of expansion of the pressing portion 81 can be adjusted according to the treatment site, and can also be adjusted according to the preference of the user and the position of the force point of the body. For example, by decreasing the amount of expansion in the thin tiptoe region from the sole to the instep and increasing the amount of expansion in the vicinity of the thick ankle, it is possible to prevent the treatment from being excessively strong, and to facilitate the movement of the treatment tool 71 from the tiptoe to the rear of the foot. Instead of the airbag 20, a mechanical pressing mechanism may be used. The pressing portion 81 may be provided instead of the foot massaging portion a7 for massaging the outer side surface of the foot.

The foot support portion 41 has a holding member 83 capable of holding the foot of the person to be treated provided on the side wall 41b from the side or from above. The clamping members 83 clamp the feet of the person to be treated, so that the feet of the person to be treated do not move with the movement of the treatment tool 71 when the treatment tool 71 is used to treat the feet, and thus the treatment can be performed more appropriately. In the present embodiment, the foot support member is disposed so as to sandwich the heel of the person to be treated, but may be provided at any position as long as the foot of the person to be treated can be sandwiched from the side or from above. The holding member 83 is constituted by the airbag 20 that is inflated and deflated by the supply and discharge of air. Instead of the airbag 20, a mechanical pressing mechanism may be used.

The foot support portion 41 has an ejecting member 84 capable of ejecting the foot of the person to be treated from the rear toward the toe. The push-out member 84 is constituted by the airbag 20 that is inflated and deflated by the supply and discharge of air, and the push-out amount can be adjusted by the control unit 9 by adjusting the supply amount of air. The ejector member 84 ejects the feet of the person to be treated in the toe direction according to the size of the feet of the person to be treated, thereby adjusting the position of the feet of the person to be treated to a position where the treatment member 71 is suitable for treating the arch of the feet. Here, the size of the foot of the treatment subject may be input by the controller 10, or other body information such as the height of the treatment subject may be input and the estimated value calculated based on the input may be used as the size of the foot of the treatment subject. Further, a sensor may be provided in the foot support 41 to detect the size and position of the foot.

In the present embodiment, the case where the massage unit 70 is provided on the foot support portion 41 has been described, but the present invention is not limited thereto, and may be provided at any position as long as it can support the upper limbs or the lower limbs like the armrest portion 6 and the leg support portion 40. The massage units 70 may be provided at a plurality of positions as in the foot support portion 41 and the leg support portion 40, and the foot support portion 41 and the armrest portion 6. Further, when the massage unit 70 is provided in the armrest portion 6 and the leg support portion 40, the size of the person to be treated and other body information such as the height may be input and estimated based on the input, similarly to the foot support portion 41, and a sensor may be further provided to detect the size and position of the upper limb and the lower limb.

The massage unit 70, the pressing part 81, the holding member 83, and the ejecting member 84 may be configured such that the right half body and the left half body of the person to be treated can be controlled to be inflated in a left-right independent manner, or may be controlled such that one half body is inflated while the other half body is deflated. With this configuration, not only can different stimuli be applied to the left and right sides to change the treatment feeling to the left and right sides, but also only the left and right half bodies are held in an emergency, thereby facilitating the body movement of the person to be treated.

[ example of action ]

Fig. 17 is a flowchart showing an example of the operation in the present invention. The position adjustment step S1 is a step of ejecting the feet of the person to be treated from the rear toward the toe by the ejection members 84 and moving the feet of the person to be treated to appropriate positions during the treatment. The holding step S2 is a step of holding and fixing the feet of the person to be treated by the holding members 83 to prevent the feet of the person to be treated from moving forward, backward, leftward, rightward, or upward and downward due to the treatment. The pressing step S3 is a step of pressing the foot of the person to be treated by the pressing part 81 to prevent the foot of the person to be treated from being lifted by the treatment of the treatment members 71 by the push-up members 78. The treatment step S4 is a step of treating the back or lower surface of the body of the user, and includes two steps, i.e., a push-up step S4a of bringing the treatment members 71 close to the back or lower surface of the body of the user by the push-up member 78 and a drive step S4b of moving the treatment members 71 by the drive unit 73 to perform treatment while tracing an elliptical orbit on the back or lower surface of the body.

The position adjustment step S1 is preferably performed before the clamping step S2 and the pressing step S3. With such a configuration, the position of the foot of the person to be treated can be easily adjusted. The holding step S2 and the pressing step S3 may precede each other.

In the treatment step S4, the amount of expansion can be adjusted by appropriately controlling the push-up member 78, the pressing part 81, the gripping member 83, and the push-out member 84. With this configuration, the position of the feet of the person to be treated and the intensity of the treatment can be adjusted according to the treatment operation, in addition to the movement of the treatment member 71 by the driving unit 73. The amount of expansion of the push-up member 78, the pressing portion 81, the holding member 83, and the push-out member 84 may be adjustable by the user. With this configuration, the user can adjust the treatment intensity and the treatment position as desired.

When the treatment is completed, all of the push-up member 78, the pressing portion 81, the holding member 83, and the push-out member 84 may be contracted at the same time, or may be contracted in an appropriately determined order.
