Detailed Description

(an example of a mode that can be adopted by a massager and a foot treatment part thereof)

An embodiment of a massage machine according to the present disclosure includes: a foot rest platform for supporting feet; and a foot treatment unit provided on the footrest so as to massage the periphery of the ankle (Japanese: くるぶし) in a concentrated manner.

By massaging the ankle, a comfortable massage feeling can be given to the foot. According to the above massage machine, the periphery of the ankle is massaged by the foot treatment unit, and thus a comfortable massage feeling can be given to the foot.

On the other hand, in the case of massaging other portions near the periphery of the ankle and the periphery of the ankle at the same time, the massage feeling felt by the user is reduced. This is related to the following: when a plurality of portions close to each other are massaged at the same time, the massage feeling given to each portion is easily blurred.

In addition, when the foot treatment portion massages the ankle periphery and other portions at the same time, the force applied by the foot treatment portion is dispersed, and the massage feeling given to the ankle periphery is reduced. According to the massager of the present disclosure, the periphery of the ankle is massaged intensively by the foot treatment unit, and therefore, a desired massage feeling can be given to the periphery of the ankle.

An example of the massage machine according to the present disclosure may further include an adjustment unit that can adjust the intensity of the massage by the foot treatment unit.

[ 3 ] according to an example of the massage machine of the present disclosure, the foot treatment unit may include: a treatment member which is pressed to the periphery of the ankle by the force provided from the regulating portion, and which massages the periphery of the ankle in a concentrated manner; and a support portion which is mounted on the footrest table and supports the treatment member so that the intensity of the massage by the treatment member can be adjusted according to the operation of the adjustment portion.

[ 4 ] according to an example of the massage machine of the present disclosure, the treatment member may have a shape curved along the periphery of the ankle.

In the case where the treatment member has a linear shape extending along a straight line, the treatment member is difficult to fit around the ankle when the foot is placed on the footrest. Therefore, there is a concern that: the treatment member does not properly contact the periphery of the ankle, and the user feels uncomfortable.

On the other hand, according to the massage machine of the present disclosure, the treatment member is curved along the periphery of the ankle, and therefore the treatment member is easily matched with the periphery of the ankle when the foot is placed on the footrest. Therefore, the treatment member is appropriately brought into contact with the periphery of the ankle, and a desired massage feeling is easily given to the periphery of the ankle.

[ 5 ] according to an example of the massage machine of the present disclosure, the foot treatment portion may include a plurality of treatment members, and the plurality of treatment members may include a first treatment member that collectively massages a periphery of an ankle located on an inner side of the foot and a second treatment member that collectively massages a periphery of an ankle located on an outer side of the foot.

If the massage is provided around the ankle on the medial and lateral sides of the foot, respectively, a more desirable massage feeling can be given around the ankle.

According to the massage machine of the present disclosure, the peripheries of the ankles located at the inner side and the outer side of the foot, respectively, are massaged by the first treatment member and the second treatment member, and thus a more desirable massage feeling can be given to the peripheries of the ankles.

[ 6 ] according to an example of the massage machine of the present disclosure, the following structure may be adopted: the first treatment member is supported by the support portion so as to massage the spa point around the ankle, and the second treatment member is supported by the support portion so as to massage at least one of the peripheral point around the ankle and the lymph node.

If the water spring point at the periphery of the ankle is massaged, a further desirable massage feeling can be given to the periphery of the ankle located on the inner side of the foot. In addition, if at least one of the poiyuri point and the lymph node at the periphery of the ankle is massaged, a more desirable massage feeling can be given to the periphery of the ankle located on the outer side of the foot.

According to the massage machine of the present disclosure, as described above [ 6 ], since the first treatment member and the second treatment member are supported by the support portion, a more desirable massage feeling can be given to the periphery of the ankle.

In [ 7 ] an example of the massage machine according to the present disclosure, the footrest may include an inner wall and an outer wall provided to sandwich the foot, and a bottom wall supporting the sole. The support portion may include a first side portion provided to face the inner side wall and support the first treatment member, and a second side portion provided to face the outer side wall and support the second treatment member.

In [ 8 ] an example of the massage machine according to the present disclosure, the footrest may further include a back wall provided on a back surface side of the feet. The support portion may further include an intermediate portion attached to the footrest in such a manner as to face the back wall, connected to the first side portion and the second side portion, and configured such that at least one of the first side portion and the second side portion is displaceable relative to the footrest.

In the case where a strong force is applied to the ankle and the bones around it, the user tends to feel uncomfortable. However, according to the massage machine of the present disclosure, at least one of the first side portion and the second side portion is displaceable with respect to the footrest, and therefore the treatment member supported by the displaceable side portion is easily moved with respect to the foot. Therefore, even if the treatment member comes into contact with the foot bones, the feet move in response to pain or the like, and the positions of the treatment member are likely to be displaced from the foot bones. Therefore, the ankle and the bones around the ankle are not easily strongly contacted with the treatment member, and the fear that the user feels uncomfortable can be reduced.

[ 9 ] according to an example of the massage machine of the present disclosure, the following configuration may be adopted: the first side portion is attached to the footrest, and the second side portion is not fixed to any portion of the footrest, and is displaceable relative to the footrest.

In the case where a strong force is applied to the ankle and the bones around the ankle located on the outer side of the foot, the user feels discomfort more easily than in the case where a strong force is applied to the ankle and the bones around the ankle located on the inner side of the foot. This is related to the following: the ankle and its surrounding bones on the lateral side of the foot are prone to pain.

According to the massage machine of the present disclosure, the second side portion can be displaced with respect to the footrest, and therefore the position of the second treatment member is easily deviated from the foot bone. Therefore, the ankle located on the outer side of the foot and the bones around it are not easily strongly contacted with the second treatment member, and the fear that the user feels uncomfortable can be reduced. In addition, according to the massage machine of the present disclosure, the first side portion is attached to the footrest table, and therefore, the position of the first treatment member that contacts the periphery of the ankle located on the inner side of the foot is easily maintained. Therefore, a desired massage feeling can be given to the ankle area located on the inner side of the foot.

[ 10 ] according to an example of the massage machine of the present disclosure, the following configuration may be adopted: the support portion includes an airbag.

According to this massage machine, the number of components constituting the massage machine can be reduced as compared with a case where the support portion and the airbag are separately provided. Therefore, the manufacturability of the massage machine can be improved.

[ 11 ] according to an example of the massage machine of the present disclosure, the following configuration may be adopted: the airbag device further includes an airbag provided so as to overlap the support portion.

According to this massage machine, the first treatment member and the second treatment member are pressed to the periphery of the ankle by the forces of the two air bags. Therefore, the treatment member is more strongly contacted with the periphery of the ankle. Therefore, a stronger force can be applied to the periphery of the ankle, and massage of various strengths can be provided to the periphery of the ankle.

(Another example of the mode that the massage machine can take)

An embodiment of a massage machine according to the present disclosure includes: a foot rest platform for supporting feet; a treatment part which is arranged on the foot rest platform in a manner of massaging soles; and a driving portion that drives the treatment portion. The treatment unit includes a rotating roller that can rotate with respect to the footrest and a plurality of projections provided on the outer peripheral surface of the rotating roller. The plurality of convex portions include a first convex portion capable of treating the inner side of the sole and a second convex portion capable of treating the outer side of the sole, and the first convex portion is higher than the second convex portion.

The shape of a typical human foot sole is such that the medial side of the foot sole is concave relative to the lateral side. According to the massage machine having the above-described configuration, as described above [ 1 ], the relationship between the height of the first convex portion and the height of the second convex portion is set along the shape of the sole of a typical person. Therefore, compared to the case where the first convex portion is lower than the second convex portion or the first convex portion and the second convex portion have substantially the same height, the first convex portion strongly contacts the inner side of the sole of the foot, and a massage corresponding to the shape of the sole of the foot can be provided. Therefore, a desired massage feeling can be given to the sole of the foot.

Further, according to an example of the massage machine, the first projection and the second projection may be different in position in the circumferential direction of the rotating roller.

When the inner side and the outer side of the sole are massaged at the same time, the feeling of massage given to the sole is reduced. This is related to the following: only the massage of the strong stimulation to the sole of the foot gives a strong impression to the user. That is, the massage of the other side, which gives weak stimulation to the sole of the foot, does not give a strong impression to the user. On the other hand, according to the massage machine described above, since the inner side and the outer side of the sole are massaged alternately, the user is given a strong impression regardless of which of the first convex portion and the second convex portion massages. Therefore, the foot sole can be easily given an ideal massage feeling.

In the above-described example of the massage machine, the outer peripheral surface of the rotating roller may include a curved surface portion having no convex portion, and the length of the curved surface portion in the circumferential direction may be longer than the length of the first convex portion in the circumferential direction and the length of the second convex portion in the circumferential direction.

In the case of applying massage with continuous stimulation to the sole of a foot, the user is accustomed to the stimulation and is hard to give a strong impression to the user. On the other hand, according to the above-described massage machine, since the curved surface portion is provided on the outer peripheral surface of the rotating roller, the sole is massaged at predetermined intervals. Therefore, the user can feel a strong impression and the user can feel a desired massage feeling on the sole of the foot.

In the above-described example of the massage machine, a second treatment unit that massages a different part of the sole of the foot from the part massaged by the first treatment unit may be provided in addition to the first treatment unit as the treatment unit.

[ 5 ] according to the above-described example of the massage machine, the drive unit may include a relative drive unit that relatively moves the first treatment unit and the second treatment unit in the front-rear direction of the foot.

Further, according to the above-described example of the massage machine, the driving unit may further include a support shaft that supports the rotary roller, and a motor that rotates the support shaft. The relative driving unit may include an eccentric shaft that eccentrically rotates with respect to the support shaft, and a link that couples the eccentric shaft and the second treatment unit such that the second treatment unit moves relative to the first treatment unit at least in the front-rear direction of the foot.

Further, according to an example of the massage machine described above, the relative driving unit may be configured to: when one of the first and second convex portions is closest to the second treatment portion in the front-rear direction of the foot, the second treatment portion is farthest from the rotary roller.

When the second treatment part is closest to the rotary roller when one of the first convex part and the second convex part is closest to the second treatment part, the link rod needs to be long in order to prevent the first treatment part from contacting the convex part. Therefore, when the second treatment portion is farthest from the rotating roller, the interval between the second treatment portion and the rotating roller is widened. This may hinder the downsizing of the massage machine. On the other hand, according to the massage machine described above, the relative driving unit is configured as described in [ 7 ], and therefore, the massage machine can be easily downsized.

Further, according to an example of the massage machine described above, the following configuration may be adopted: the first treatment portion can massage a portion near the arch of the sole of the foot, and the second treatment portion can massage a portion near the root of the toes of the foot.

(Another example of the manner in which the massage machine can be used)

An embodiment of a massage machine according to the present disclosure includes: a foot rest platform for supporting feet; a treatment part which is arranged on the foot rest platform in a manner of massaging soles; and a driving portion that drives the treatment portion. Further, the structure is as follows: the treatment unit includes a rotary roller that is rotatable with respect to the footrest and an arc-shaped projection provided on the outer peripheral surface of the rotary roller, the projection includes a plurality of ribs provided on at least one of the side surfaces thereof and a rib space surrounded by the plurality of ribs, and the plurality of ribs are provided on the side surfaces so as to form a rib space having a size that does not allow toes to enter.

According to the massager having such a configuration, since the convex portion has a circular arc shape, the stress concentration at the root of the convex portion can be reduced as compared with the case where the convex portion has a rod shape. In addition, since the ribs are provided on the side surfaces of the convex portions, the convex portions are reinforced. Therefore, the possibility of damage to the projection can be reduced. However, depending on the pattern of the ribs formed on the convex portion, toes may enter a space surrounded by the ribs. On the other hand, in the massager of the present disclosure, since the plurality of ribs are provided in consideration of this point, it is possible to reduce the fear that toes enter the rib space.

Further, according to the above-described example of the massage machine, the rib may include a first rib having a shape similar to the shape of the outer periphery of the convex portion.

Further, according to an example of the above-described massage machine, the ribs may further include second ribs extending in the radial direction of the convex portion.

Further, according to the above-described example of the massage machine, both side surfaces of the convex portion may have substantially the same configuration.

Further, according to the above-described example of the massage machine, the rotating roller may have a hollow cylindrical shape, and the rotating roller may include a first roller rib that partitions a space in the cylindrical shape in a radial direction of the rotating roller and a second roller rib that partitions a space in the cylindrical shape in a circumferential direction of the rotating roller.

(Another example of the manner in which the massage machine can be used)

An embodiment of a massage machine according to the present disclosure includes: a foot rest platform for supporting feet; a first treatment part which is arranged on the foot placing platform in a manner of massaging soles; a second treatment part provided on the foot rest platform in a manner that the second treatment part can massage other parts of the sole different from the parts massaged by the first treatment part; and a driving portion that drives at least the first treatment portion. The first treatment unit may include a rotating roller that is rotatable with respect to the footrest and at least one convex portion provided on an outer peripheral surface of the rotating roller, and the outer peripheral surface of the rotating roller may include a curved surface portion on which the convex portion is not provided so that the sole of the foot can be supported without contacting the convex portion.

According to this massage machine, the relationship between the convex portion and the curved surface portion and the sole changes with the rotation of the rotary roller. When the second treatment unit does not massage the sole of the foot in a state where the convex portion massages the sole of the foot, the user feels only a massage feeling given to the sole of the foot by the first treatment unit. Therefore, the user can feel a strong impression of the massage applied to the sole of the foot more easily than in the case where the sole of the foot is massaged by both the first treatment portion and the second treatment portion. On the other hand, when the curved surface portion is in contact with the sole, the first treatment portion does not substantially massage the sole.

When the second treatment portion massages the sole in this state, the user feels only the massage feeling given to the sole by the second treatment portion. Therefore, the user can feel a strong impression of the massage applied to the sole of the foot more easily than in the case where the sole of the foot is massaged by both the first treatment portion and the second treatment portion. Thus, the massage machine having the above-described configuration can massage the sole of a foot with a strong impression.

Further, according to an example of the massage machine described above, the second treatment unit may include at least one convex portion for massaging the sole of the foot. The first treatment portion and the second treatment portion may be provided on the footrest so that a position of a tip of the convex portion of the first treatment portion when the tip contacts the sole is higher than a position of the tip of the convex portion of the second treatment portion when the tip contacts the sole.

According to this massage machine, when the convex portion of the first treatment unit and the convex portion of the second treatment unit are in contact with the sole of the foot, the sole of the foot is strongly massaged by the convex portion of the first treatment unit. That is, even when the curved surface portion does not contact the sole of the foot and the convex portion of each treatment portion contacts the sole of the foot, the sole of the foot can be massaged with a strong impression.

Further, according to the above-described massage machine, the drive unit may include a relative drive unit that relatively moves the first treatment unit and the second treatment unit in the front-rear direction of the foot.

Further, according to the above-described example of the massage machine, the driving unit may further include a support shaft that supports the rotary roller, and a motor that rotates the support shaft. The relative driving unit may include an eccentric shaft that eccentrically rotates with respect to the support shaft, and a link that couples the eccentric shaft and the second treatment site such that the second treatment site moves relative to the first treatment site at least in the front-rear direction of the foot.

Further, according to an example of the massage machine described above, the relative driving unit may be configured to: the second treatment part is farthest away from the rotary roller when the convex part of the first treatment part is closest to the second treatment part in the front-back direction of the foot.

In the case where the second treatment portion is configured to be closest to the rotating roller when the second treatment portion is closest to the convex portion, the link needs to be long in order to prevent the second treatment portion from contacting the convex portion. Therefore, when the second treatment portion is farthest from the rotating roller, the interval between the second treatment portion and the rotating roller is widened. This may hinder downsizing of the massage machine. On the other hand, according to the massage machine of the present disclosure, since the relative driving portion is configured as [ 5 ], it is easy to miniaturize the massage machine.

[ 6 ] according to an example of the massage machine described above, the relative driving unit may be configured to: when the curved surface portion of the foot is closest to the second treatment portion in the front-rear direction, the second treatment portion is closest to the rotary roller.

According to the massage machine having such a configuration, since the relative driving portion is configured as described in [ 6 ], it is easy to miniaturize the massage machine, compared with the case where the second treatment portion is closest to the rotating roller when the second treatment portion is closest to the convex portion.

In the above-described example of the massage machine, the convex portion of the second treatment unit may be provided in the relative driving unit so as to massage at least one of the thenar region, the hypothenar region, and a range therebetween. Further, the relative driving unit may be configured to: the sole of the foot contacts the curved surface portion when the second treatment portion moves rearward in the front-rear direction of the foot.

The massage feeling can be enhanced by massaging the thenar, hypothenar, and the area therebetween while moving the convex portion from the front to the rear. According to the massage machine described above, in order to obtain such an effect, the curved surface portion comes into contact with the sole when the second treatment unit is operated, and therefore the user can easily feel a stronger impression of the massage applied to the sole by the second treatment unit.

Further, according to an example of the above-described massage machine, the first treatment unit may further include a plurality of protrusions.

The above-described example of the massage machine may further include a frame that forms an outer frame of the footrest and supports the support shaft so that the support shaft can rotate. Further, the frame may include a support frame that is held at a position in the height direction of the second treatment portion footrest.

[ 10 ] according to an example of the massage machine described above, the following configuration may be adopted: the supporting tube supports the bottom of the second treatment portion.

[ 11 ] according to an example of the massage machine described above, the following configuration may be adopted: the curvatures of the plurality of convex portions are different from each other.

[ 12 ] according to an example of the massage machine described above, the following configuration may be adopted: the plurality of convex portions include a first convex portion and a second convex portion lower than the first convex portion, and the curvature of the second convex portion is larger than the curvature of the first convex portion.

For example, two outer leg airbags 122 are provided on each of the surface of the support leg of the surface constituting one outer side wall 112 and the surface of the support leg of the surface constituting the other outer side wall 112.

In the present embodiment, two of the plurality of leg-back airbags 123 are used as an example. For example, the leg-back airbags 123 are provided one on each of the surface of the back wall 113 that supports one leg and the surface of the back wall 113 that supports the other leg.

According to this structure, the leg is massaged by repeated inflation and deflation of the inner leg airbag 121, the outer leg airbag 122, and the leg back airbag 123.

The footrest 130 further includes a plurality of inner foot airbags 141 and a plurality of outer foot airbags 142.

In the present embodiment, two airbags 141 are provided as an example of the number of the plurality of inner leg airbags. The inner airbag 141 is provided, for example, on one of the surfaces constituting the inner wall 131 for supporting one foot and on the other of the surfaces constituting the inner wall 131 for supporting the other foot.

In the present embodiment, two outer leg airbags 142 are provided as an example of the number. For example, one of the outer leg airbags 142 is provided on each of the surface of the one outer side wall 132 that supports one leg and the surface of the other outer side wall 132 that supports the other leg.

The foot is massaged by repeated expansion and contraction of the inner foot bladder 141 and the outer foot bladder 142. The inflated state of the inner leg airbag 141 and the outer leg airbag 142 is maintained, whereby the position of the foot with respect to the footrest 130 is maintained.

The leg rest 100 further includes a sole treatment block 200 and a pair of foot treatment portions 300. The foot treatment part 300 functions to massage the circumference of the ankle intensively. The foot treatment unit 300 is attached to the footrest 130, for example. The foot treatment unit 300 is covered with, for example, the cover 136 (see fig. 1).

The sole treatment block 200 includes a pair of sole treatment portions 210 and a drive portion 240 (see fig. 4). The sole treatment part 210 functions to massage the sole. Each of the sole treatment portions 210 is provided, for example, in a pair of concave portions 133A, and the pair of concave portions 133A are formed on a surface that supports a foot, out of the surfaces that constitute the bottom wall 133 (see fig. 2). A part of the sole treatment portion 210 is exposed from the concave portion 133A. The sole treatment portion 210 is covered with, for example, the cover 136 (see fig. 1).

The driving unit 240 shown in fig. 4 functions to drive the sole treatment unit 210. The driving unit 240 is provided inside the footrest 130, for example. The driving portion 240 includes a support shaft 241, a motor 242, and a pair of opposing driving portions 243.

Fig. 3 is a view showing a cross-sectional structure of the footrest 130 in the embodiment of the present disclosure.

The sole treatment part 210 includes a first treatment part 220 and a second treatment part 230.

The first treatment portion 220 functions to massage a portion of the sole near the arch of the foot.

The second treatment application part 230 functions to massage other portions of the sole of the foot different from the portion massaged by the first treatment application part 220. In one example of the present embodiment, the second treatment unit 230 is provided at a position where the vicinity of the root of the toe of the sole can be massaged.

The relative driving unit 243 functions to relatively move the first treatment unit 220 and the second treatment unit 230 in the front-rear direction of the foot. The relative driving unit 243 couples the first treatment unit 220 and the second treatment unit 230 to each other so that the first treatment unit 220 and the second treatment unit 230 can move relatively. Further, the front-rear direction of the foot is a direction along the front-rear direction of the footrest 130.

The cover 136 includes a reinforcing portion 136A. The reinforcement portion 136A functions to improve the durability of the cover 136. The reinforcement portion 136A is made of, for example, an elastic material. The reinforcement portion 136A is formed, for example, at a portion of the cover 136 that strongly contacts the ball treatment portion 210. In the example shown in fig. 3, the reinforcement portion 136A is provided at a portion of the sole treatment portion 210 that contacts the first treatment portion 220. According to this structure, the cover 136 is less likely to be worn by contact with the first treatment site 220.

The back wall 134 constituting the footrest 130 is coupled with the bottom wall 133, for example, in an inclined manner with respect to the bottom wall 133. Specifically, the angle formed by the bottom wall 133 and the back wall 134 at the inner wall 131 and the outer wall 132 side is formed to be an obtuse angle. Thus, the user can easily slide the foot along the back wall 134 so that the foot is placed at an appropriate position of the footrest 130. Further, a cover 136 is provided along at least the inner side of the back wall 134, obliquely to the bottom wall 133.

Fig. 4 is a perspective view showing an internal structure of the footrest 130 in the embodiment of the present disclosure.

The driving unit 240 includes a support shaft 241, a motor 242, and a pair of opposing driving units 243.

The support shaft 241 functions to support each of the first treatment applying portions 220. The support shaft 241 extends in the width direction of the footrest 130.

The motor 242 functions to rotate the support shaft 241. The motor 242 rotates, and the support shaft 241 rotates via a worm gear (not shown) or the like, and each first treatment applying portion 220 rotates as it rotates. The motor 242 is housed in, for example, an inner wall 131 (see fig. 2) of the footrest 130.

The footrest 130 also includes a frame 135. The frame 135 functions to rotatably support the support shaft 241. The frame 135 forms the outer contour of the footrest 130. The frame 135 includes an inner sidewall frame 135A, a pair of outer sidewall frames 135B, a back wall frame 135C, and a support frame 135D.

The inner wall frame 135A extends in the front-rear direction of the footrest 130 and is housed in the inner wall 131.

The pair of outer side wall frames 135B extend in the front-rear direction of the footrest 130, and are respectively housed in the corresponding outer side walls 132 (see fig. 2). One outer wall frame 135B supports one end of the support shaft 241 so that the one end of the support shaft 241 is rotatable. The other outer sidewall frame 135B supports the other end of the support shaft 241 so that the other end of the support shaft 241 is rotatable.

The back wall frame 135C extends in the width direction of the footrest 130 and is housed in the back wall 134 (see fig. 1). The back wall frame 135C is connected to the inner wall frame 135A and the pair of outer wall frames 135B.

The support frame 135D functions to hold the position of the second treatment site 230 in the height direction of the footrest 130. The support frame 135D extends in the width direction of the footrest 130 and is housed in the bottom wall 133 (see fig. 2). The support frame 135D is provided forward of the support shaft 241 in the front-rear direction of the footrest 130 and below the second treatment portion 230 in the height direction of the footrest 130, and connects the pair of outer side wall frames 135B to each other. The support frame 135D supports the bottom of the second treatment site 230, for example, so as not to restrict the movement of the second treatment site 230 in the front-rear direction of the footrest 130. That is, the second treatment site 230 is placed on the support frame 135D. Therefore, the second treatment site 230 can move in the front-rear direction of the footrest 130 while maintaining its position in the height direction of the footrest 130 by the support frame 135D.

Fig. 5 is a perspective view of a sole treatment block for explaining the structure of the sole treatment unit 210 according to the embodiment of the present disclosure.

The first treatment portion 220 includes a rotating roller 221, a first protrusion 222, and a second protrusion 223. A support shaft 241 is inserted into the center of the rotary roller 221, and the rotary roller 221 rotates together with the rotation of the support shaft 241.

The first convex portion 222 functions to treat the inner side of the sole of the foot. The medial aspect of the sole of the foot includes the area near the arch of the foot. First convex portion 222 is provided on the outer circumferential surface of rotating roller 221, for example, and is formed in an arc shape. Therefore, the degree of stress concentration generated at the root of the first convex portion 222 can be alleviated.

The second convex portion 223 functions to treat the outer side of the sole of the foot. The second convex portion 223 is provided on the outer circumferential surface of the rotating roller 221, for example, and is formed in an arc shape. Therefore, the degree of stress concentration generated at the root of the second convex portion 223 can be alleviated.

For example, the positions of the first convex portion 222 and the second convex portion 223 in the axial direction of the rotating roller 221 and the positions in the circumferential direction of the rotating roller 221 are different.

The outer circumferential surface of the rotating roller 221 includes a curved surface portion 224. The curved surface portion 224 is not provided with a convex portion, so that the sole can be supported so as not to contact the first convex portion 222 and the second convex portion 223. The length of the curved surface portion 224 in the circumferential direction is longer than the length of the portion where the first convex portion 222 is provided and the length of the portion where the second convex portion 223 is provided in the circumferential direction.

The second treatment portion 230 includes a first protrusion 231, a second protrusion 232, a third protrusion 233, and a support table 234. The support table 234 functions to support the first, second, and third

convex portions

231, 232, and 233. The support table 234 is supported by the support frame 135D (see fig. 3).

The first convex portion 231 functions to massage a portion of the sole near the thenar.

The third protrusions 233 function to massage the portions of the sole near the hypothenar.

The second convex portion 232 functions to massage a portion of the sole in the range between the greater thenar and the lesser thenar.

That is, the second convex portion 232 is provided between the first convex portion 231 and the third convex portion 233 in the axial direction of the rotating roller 221. The first, second, and third

convex portions

231, 232, and 233 have a shape like a rod, for example, and extend upward from the support base 234.

The first convex portion 231 has a lower height than the second and third

convex portions

232 and 233. The second convex portion 232 is higher than the first and third

convex portions

231 and 233. The third convex portion 233 is higher than the first convex portion 231 and lower than the second convex portion 232. The relationship of the heights of the first, second, and

third protrusions

231, 232, 233 is set to a shape along the thenar, hypothenar, and the range between the thenar and hypothenar, respectively. Therefore, a desired massage feeling can be given to the portion of the sole near the root of the toes.

The leg placement section 100 further includes a first detection section 251 and a second detection section 252.

The first detecting portion 251 functions to detect the rotation state of the rotating roller 221. The first detection portion 251 is provided around the support shaft 241, for example.

The second detection unit 252 has a function of detecting the rotation speed, the rotation direction, and the like of the motor 242. The second detection portion 252 is provided near the output shaft of the motor 242.

The first detection unit 251 and the second detection unit 252 output the detected information to the control device, for example.

Fig. 6 is a perspective view showing the structure of the first treatment unit 220 in the embodiment of the present disclosure.

One example of the shape of the rotating roller 221 is a hollow cylinder. The rotating roller 221 includes a plurality of first roller ribs 221A, a second roller rib 221B, and a plurality of roller rib spaces 221C.

The first roller rib 221A is a rib that partitions the space in the cylinder in the radial direction of the rotating roller 221.

The second roller rib 221B is a rib that partitions the space in the cylinder in the circumferential direction of the rotating roller 221.

The plurality of first roller ribs 221A include, for example, a plurality of first roller ribs 221A extending from the inner circumferential surface of the outer cylinder of the rotating roller 221 to the second roller rib 221B, and a plurality of first roller ribs 221A extending from the second roller rib 221B to the rotation center of the rotating roller 221.

The roller rib space 221C is a space formed by being surrounded by the plurality of first roller ribs 221A, second roller ribs 221B, and the like. The plurality of first roller ribs 221A, the second roller ribs 221B, and the plurality of roller rib spaces 221C are provided on, for example, one side surface of the rotating roller 221.

The first convex portion 222 includes a plurality of first ribs 222A, a second rib 222B, and a plurality of rib spaces 222C.

The first rib 222A has a shape similar to the shape of the outer periphery of the first convex portion 222, for example, and is provided on the side surface of the first convex portion 222. The second rib 222B is provided on a side surface of the first protrusion 222 along the radial direction of the first protrusion 222. In the example shown in fig. 6, the second ribs 222B extend in a substantially vertical direction from the outer circumferential surface of the rotating roller 221.

The plurality of rib spaces 222C are spaces formed by being surrounded by the plurality of first ribs 222A, the second ribs 222B, the inner circumferential surface of the first convex portion 222, the outer circumferential surface of the rotating roller 221, and the like. In the example shown in fig. 6, the rib space 222C forms an arc-shaped groove. The plurality of first ribs 222A and the plurality of second ribs 222B are provided on the side surface of the first protrusion 222 so as to form a rib space 222C having a size that does not allow toes to enter. Therefore, safety at the first convex portion 222 can be improved. Both side surfaces of the first protrusion 222 have substantially the same structure. An example of the size of the rib space 222C, into which toes cannot enter, is 5mm or less.

The second convex portion 223 includes a plurality of ribs 223A and rib spaces 223B.

The rib 223A has a shape similar to the shape of the outer periphery of the second convex portion 223, for example, and is provided on the side surface of the second convex portion 223.

The rib space 223B is a space surrounded by the plurality of ribs 223A, the inner circumferential surface of the second convex portion 223, the outer circumferential surface of the rotating roller 221, and the like. In the example shown in fig. 6, the rib space 223B forms an arc-shaped groove. The plurality of ribs 223A are provided on the side surface of the second convex portion 223 so as to form a rib space 223B having a size that does not allow toes to enter. Therefore, safety at the second convex portion 223 can be improved. Both side surfaces of the second convex portion 223 have substantially the same structure.

Fig. 7 is a side view of the sole treatment unit 210 showing the relationship between the sole treatment unit 210 and the relative driving unit 243 in the embodiment of the present disclosure.

The first convex portion 222 is higher than the second convex portion 223. Specifically, first distance CH1, which is the distance between the outer circumferential surface of rotating roller 221 and the tip of first convex portion 222, is longer than second distance CH2, which is the distance between the outer circumferential surface of rotating roller 221 and the tip of second convex portion 223. Therefore, the first convex portion 222 is exposed from the concave portion 133A (see fig. 3) of the footrest 130, as compared with the second convex portion 223.

The shape of a typical human foot sole is such that the medial side of the foot sole is concave relative to the lateral side. The relationship between the height of the first convex portion 222 and the height of the second convex portion 223 is set to follow the shape of the sole of the foot of the average person. Therefore, as compared with the case where the height of the first convex portion 222 is lower than the height of the second convex portion 223 and the case where the height of the first convex portion 222 is substantially the same as the height of the second convex portion 223, the first convex portion 222 strongly contacts the inner side of the sole of the foot, and a massage according to the shape of the sole of the foot can be provided. Therefore, a desired massage feeling can be given to the sole of the foot.

The curvature of the surface in contact with the sole of the first convex portion 222 and the curvature of the surface in contact with the sole of the second convex portion 223 are different from each other. In one example, the curvature of the second convex portion 223 is larger (radius of curvature is smaller) than the curvature of the first convex portion 222. Therefore, the second convex portion 223 can give a stronger stimulation to the sole of the foot than the first convex portion 222 when contacting the sole of the foot.

The counter drive unit 243 includes an eccentric shaft 243A and a connecting rod 243B. Eccentric shaft 243A is provided at a position offset from the rotation center of rotation roller 221, for example, on the other (inner) side surface of rotation roller 221. By the rotation of the support shaft 241, the eccentric shaft 243A rotates around the support shaft 241 together with the rotation roller 221. Therefore, the position of the eccentric shaft 243A relative to the rotating roller 221 moves in the front-rear direction and the height direction of the foot. That is, the eccentric shaft 243A eccentrically rotates with respect to the support shaft 241.

The connecting rod 243B functions to convert an eccentric motion by rotation of the eccentric shaft 243A into a linear motion along the front-rear direction of the foot. The connecting rod 243B connects the eccentric shaft 243A with the support base 234 of the second treatment unit 230 so that the second treatment unit 230 moves in the front-rear direction of the foot with respect to the first treatment unit 220. The eccentric shaft 243A and the connecting rod 243B are coupled to each other so as to rotate relative to each other. Therefore, the eccentric shaft 243A eccentrically rotates, the connecting rod 243B linearly moves in the front-rear direction of the foot, and the second treatment unit 230 moves in the front-rear direction of the foot with respect to the first treatment unit 220.

Further, since the position of the eccentric shaft 243A relative to the rotating roller 221 also moves in the height direction of the leg by the rotation of the support shaft 241, the connecting portion between the connecting rod 243B and the eccentric shaft 243A also moves in the height direction of the leg. Therefore, the second treatment site 230 swings so that the positions of the distal ends of the first, second, and third

convex portions

231, 232, and 233 change in the height direction of the feet.

The first treatment portion 220 and the second treatment portion 230 are provided on the footrest 130 such that the positions of the distal ends of the first convex portion 222 and the second convex portion 223 of the first treatment portion 220 when they are in contact with the sole are higher than the positions of the distal ends of the first convex portion 231, the second convex portion 232, and the third convex portion 233 of the second treatment portion 230 when they are in contact with the sole (see fig. 3). Therefore, the first convex portion 222 and the second convex portion 223 of the first treatment site 220 are in contact with the cover 136 (see fig. 3) more strongly than the first convex portion 231, the second convex portion 232, and the third convex portion 233 of the second treatment site 230.

The relative driving unit 243 is configured to: when the first protrusion 222 of the first treatment unit 220 and the second treatment unit 230 are closest to each other in the front-rear direction of the foot, the second treatment unit 230 is farthest from the rotating roller 221 (see fig. 10). That is, when the position of the eccentric shaft 243A with respect to the rotation roller 221 is the forefront position in the front-rear direction of the foot, the first convex portion 222 is located at a position facing the second treatment site 230 in the circumferential direction of the rotation roller 221.

With the configuration of the counter drive unit 243 as described above, the following effects can be obtained.

When it is desired to adopt a structure in which the second treatment applying portion 230 is closest to the rotating roller 221 when the second treatment applying portion 230 is closest to the first protrusion 222, the link 243B needs to be long so that the second treatment applying portion 230 does not contact the first protrusion 222. Therefore, the interval between the second treatment applying portion 230 and the rotating roller 221 may be widened when the second treatment applying portion 230 is farthest from the rotating roller 221. This may hinder downsizing of the massage machine. On the other hand, in the massage machine 1 of the present disclosure, since the relative driving unit 243 is configured as described above, the massage machine 1 can be easily downsized.

The relative driving unit 243 is configured to: when the curved surface portion 224 and the second treatment unit 230 are closest to each other in the front-rear direction of the foot, the second treatment unit 230 is closest to the rotating roller 221 (see fig. 8). That is, when the position of the eccentric shaft 243A with respect to the rotation roller 221 is the rearmost position in the front-rear direction of the foot, a part of the curved surface portion 224 is located opposite to the second treatment site 230 in the circumferential direction of the rotation roller 221. Thus, compared to the configuration in which the second treatment unit 230 is closest to the rotating roller 221, when the second treatment unit 230 is closest to the first projection 222 and the second projection 223, the massager 1 can be easily downsized.

The relative driving unit 243 is configured to: when the second treatment unit 230 is moved backward in the front-rear direction of the foot, the sole of the foot comes into contact with the curved surface portion 224. That is, in the process in which the position of eccentric shaft 243A with respect to rotation roller 221 moves from the front to the rear in the front-rear direction of the foot, curved surface portion 224 takes a position facing the sole of the foot in the circumferential direction of rotation roller 221. Specifically, the curved surface portion 224 is maintained in contact with the sole of the foot while the rotating roller 221 rotates from the state shown in fig. 11 to the state shown in fig. 8.

Fig. 8 to 11 are side views showing the relationship between the sole treatment portion 210 and the sole for explaining the operation of the sole treatment portion 210 according to the embodiment of the present disclosure.

By the rotation of the support shaft 241, the rotating roller 221 is in the first rotation state, the second rotation state, the third rotation state, and the fourth rotation state in this order.

As shown in fig. 8, in the rotation roller 221, as the first rotation state which is the initial state, for example, the position of the eccentric shaft 243A with respect to the rotation roller 221 is the rearmost position in the front-rear direction of the leg. In the first rotation state, the curved surface portion 224 of the first treatment unit 220 and the first, second, and third

convex portions

231, 232, and 233 of the second treatment unit 230 contact the sole of the foot. Therefore, compared to a case where the first convex portion 222 and the second convex portion 223 of the first treatment unit 220 contact the sole when the user who uses the massage machine 1 places his or her foot on the footrest 130, it is less likely to give a strong stimulus to the sole.

Then, the rotation roller 221 starts rotating from the first rotation state by the rotation of the support shaft 241.

As shown in fig. 9, as the second rotation state, for example, the position of eccentric shaft 243A with respect to rotation roller 221 is the highest position in the height direction of the leg. That is, the second rotation state is a state in which the rotating roller 221 in the first rotation state is rotated by 90 ° counterclockwise from the state shown in fig. 8 when viewed from the side. In the process of the rotation roller 221 changing from the first rotation state to the second rotation state, the first protrusion 222 of the first treatment unit 220 and the first protrusion 231, the second protrusion 232, and the third protrusion 233 of the second treatment unit 230 contact the sole of the foot. Therefore, the inner side of the sole is massaged by the first convex portion 222, and the portion near the root of the toes in the sole is massaged by the first convex portion 231, the second convex portion 232, and the third convex portion 233 of the second treatment portion 230.

Next, as shown in fig. 10, as a third rotation state of rotation roller 221, for example, the position of eccentric shaft 243A with respect to rotation roller 221 is the foremost position in the front-rear direction of the leg. That is, the third rotation state is a state in which the rotation roller 221 in the second rotation state is rotated by 90 ° counterclockwise from the state shown in fig. 9 when viewed from the side. In the process of the rotation roller 221 changing from the second rotation state to the third rotation state, the second convex portion 223 of the first treatment portion 220 and the first convex portion 231, the second convex portion 232, and the third convex portion 233 of the second treatment portion 230 contact the sole of the foot. Therefore, the outer side of the sole is massaged by the second convex portion 223, and the portion near the root of the toes in the sole is massaged by the first convex portion 231, the second convex portion 232, and the third convex portion 233 of the second treatment portion 230.

Next, as shown in fig. 11, in the fourth rotation state of rotation roller 221, for example, the position of eccentric shaft 243A with respect to rotation roller 221 is the lowest position in the height direction of the leg. That is, the fourth rotation state is a state in which the rotation roller 221 in the third rotation state is rotated by 90 ° counterclockwise from the state shown in fig. 10 when viewed from the side. In the process of the rotation roller 221 changing from the third rotation state to the fourth rotation state, the curved surface portion 224 of the first treatment unit 220 and the first, second, and third

convex portions

231, 232, and 233 of the second treatment unit 230 contact the sole of the foot.

The first treatment unit 220 does not substantially massage the sole of the foot in a state where the curved surface portion 224 of the first treatment unit 220 is in contact with the sole of the foot. In this state, when the sole is massaged by the first, second, and third

convex portions

231, 232, and 233 of the second treatment unit 230, the user feels only the massage feeling given to the sole by the first, second, and third

convex portions

231, 232, and 233.

For example, consider the following case: the first convex 231, the second convex 232, and the third convex 233 of the second treatment unit 230 are used to massage the sole of the foot in a state where the first convex 222 and the second convex 223 of the first treatment unit 220 are in contact with the sole of the foot. In this case, the first convex portion 222 and the second convex portion 223 of the first treatment unit 220 exert a stronger force on the sole than the second treatment unit 230, and thus the user does not easily feel a strong impression of the massage applied to the sole by the second treatment unit 230. On the other hand, in the fourth rotation state shown in fig. 11, since the first treatment unit 220 does not substantially massage the sole of the foot, the user can easily feel a strong impression of the massage applied to the sole of the foot by the first convex portion 231, the second convex portion 232, and the third convex portion 233 of the second treatment unit 230. Therefore, a desired massage feeling can be given to the portion of the sole near the root of the toes.

Then, the rotating roller 221 is rotated counterclockwise by 90 ° in side view from the state shown in fig. 11, that is, the fourth rotating state, to shift to the first rotating state shown in fig. 8. In the process of the rotation roller 221 changing from the fourth rotation state to the first rotation state, the curved surface portion 224 of the first treatment unit 220 and the first, second, and third

convex portions

231, 232, and 233 of the second treatment unit 230 contact the sole of the foot. At this time, the first convex portion 231, the second convex portion 232, and the third convex portion 233 contact the sole while moving backward in the front-rear direction of the foot, and thus the portion of the sole near the root of the toes is massaged in a scratching manner. Therefore, the user can easily feel a stronger impression of the massage applied to the sole by the first convex portion 231, the second convex portion 232, and the third convex portion 233.

In this way, by the rotation of the support shaft 241, the rotating roller 221 repeatedly enters the first rotation state, the second rotation state, the third rotation state, and the fourth rotation state. Then, the power supply of the massage machine 1 is set to off, whereby the operation of the massage machine 1 is stopped after the rotation roller 221 has formed the first rotation state as the initial state. When the support shaft 241 is rotated to rotate the rotary roller 221 clockwise as viewed from the side as shown in fig. 8, the rotary roller 221 repeatedly enters the first rotation state, the fourth rotation state, the third rotation state, and the second rotation state in this order.

Fig. 12 and 13 are bottom views for explaining the relationship between the sole treatment portion 210 and the sole when the foot is placed on the footrest 130 in the embodiment of the present disclosure.

Fig. 12 shows the relationship between the sole treatment portion 210 and the sole when the second treatment portion 230 is located at the forefront in the front-rear direction of the foot, and fig. 13 shows the relationship between the sole treatment portion 210 and the sole when the second treatment portion 230 is located at the rearmost in the front-rear direction of the foot.

By the rotation of the rotating roller 221, the first convex portion 222 of the first treatment unit 220 comes into contact with a portion near the arch of the sole. Therefore, the portion of the sole near the arch is massaged by the first convex portion 222.

The second convex portions 223 of the first treatment unit 220 are brought into contact with the outer side of the arch of the foot by the rotation of the rotating roller 221. Therefore, the second convex portion 223 massages a portion of the sole located on the outer side of the arch.

In the front-rear direction of the sole, the position of the sole contacted by the first convex portion 222 is substantially the same (including the same) as the position of the sole contacted by the second convex portion 223.

As shown in fig. 12, the second treatment portion 230 is in contact with a portion of the sole near the base of the toes. Specifically, the first convex portion 231 contacts a portion of the sole near the base of the big toe, the second convex portion 232 contacts a portion of the sole near the base of the index and middle toes, and the third convex portion 233 contacts a portion of the sole near the base of the ring and little toe. Therefore, the portions of the sole near the root of each toe are massaged by the first convex portions 231, the second convex portions 232, and the third convex portions 233.

In the state shown in fig. 13, the second treatment units 230 contact the rear part of the base of the toes in the sole of the foot. Specifically, the first convex portion 231 contacts a portion of the sole near the thenar, the second convex portion 232 contacts a portion of the sole in the range between the thenar and the hypothenar, and the third convex portion 233 contacts a portion of the sole near the hypothenar. Therefore, the greater thenar, the lesser thenar, and the areas between the greater thenar and the lesser thenar are massaged by the first convex portion 231, the second convex portion 232, and the third convex portion 233, respectively.

The area massaged by the first convex portion 231, the second convex portion 232, and the third convex portion 233 depends on the shape, size, and the like of the foot.

Fig. 14 is a front view showing a state after the foot treatment unit 300 is deployed in the embodiment of the present disclosure.

The foot treatment part 300 includes a first treatment member 311, a second treatment member 312, and a support part 320.

The first treatment member 311 functions to intensively massage around the ankle located at the inner side of the foot. The second treatment member 312 functions to intensively massage around the ankle located at the outer side of the foot.

By massaging the ankle, a comfortable massage feeling can be given to the foot. Therefore, it is possible to give a comfortable massage feeling to the foot by massaging the periphery of the ankle with the first treatment member 311 and the second treatment member 312. On the other hand, in the case of simultaneously massaging the periphery of the ankle and other portions near the periphery of the ankle, the massage feeling felt by the user is reduced. This is related to the following: when a plurality of portions close to each other are massaged at the same time, the feeling of massage given to each portion is easily blurred. In addition, when the foot treatment units 300 massage the ankle and also massage other parts at the same time, the force applied by the foot treatment units 300 is dispersed, and the massage feeling given to the ankle is reduced.

However, according to the foot treatment part 300 shown in fig. 14 of the present disclosure, the circumference of the ankle is massaged intensively by the first treatment member 311 and the second treatment member 312, and thus a desired massage feeling can be given to the circumference of the ankle.

One example of the material of the first treatment member 311 and the second treatment member 312 is TPV (thermoplastic-Vulcanizates) resin. The first treatment member 311 and the second treatment member 312 are supported by the support portion 320.

The support portion 320 functions to support the first treatment member 311 and the second treatment member 312 in such a manner that the intensity of the massage by the first treatment member 311 and the second treatment member 312 can be adjusted. The support portion 320 includes a first side portion 321, a second side portion 322, and a middle portion 323.

The first side portion 321 functions to support the first treatment applying member 311. The second side portion 322 functions to support the second treatment applying member 312. The middle portion 323 is a portion connecting the first side portion 321 and the second side portion 322.

The support portion 320 includes an airbag. In one example, the support portion 320 constitutes an airbag. Thus, the number of components constituting the massage machine 1 can be reduced as compared with the case where the support portion 320 and the airbag are provided separately.

The support portion 320 further includes a non-expanded portion 323A and a gas supply port 323B.

The non-expanded portion 323A is a portion of the support portion 320 that is not expanded, and is formed by, for example, welding one surface and the other surface of the support portion 320 to each other. The non-expansion portion 323A is provided in the intermediate portion 323, for example. That is, the intermediate portion 323 does not substantially expand.

Air supply port 323B is a hole for supplying air into support portion 320. The gas supply port 323B is provided in the intermediate portion 323, for example. The air supply port 323B is connected to an air pump 340, and the air pump 340 is an adjustment unit constituting a part of the massage machine 1.

By supplying air from the air pump 340, the first side portion 321 and the second side portion 322 in the support portion 320 are inflated, and the first treatment member 311 and the second treatment member 312 are pressed to the periphery of the ankle. That is, the air pump 340 can adjust the intensity of the massage by the foot treatment unit 300. The air pump 340 is connected to the air supply ports 323B of both the pair of foot treatment units 300.

The shapes of the first treatment member 311 and the second treatment member 312 are respectively a shape curved along the circumference of the ankle. By adopting such a shape, when the foot is placed on the footrest 130 (see fig. 15), the first treatment member 311 and the second treatment member 312 are easily fitted around the ankle. Therefore, the first treatment member 311 and the second treatment member 312 are appropriately in contact with the periphery of the ankle, and a desired massage feeling can be given to the periphery of the ankle.

The first treatment member 311 and the second treatment member 312 have a line-symmetric relationship with respect to the center line in the width direction of the support portion 320, for example. In the example shown in fig. 14, the first treatment member 311 and the second treatment member 312 are curved so as to form a figure of eight on the support portion 320. That is, the first treatment member 311 is supported by the support portion 320 so as to massage the spa FS (see fig. 16) around the ankle. The second treatment member 312 is supported by the support portion 320 so as to massage at least one of the peripheral acupoint FB and the lymph node FL (see fig. 17) around the ankle.

The support portion 320 further includes a first fixing portion 331, a second fixing portion 332, and a third fixing portion 333 (see fig. 14). The first fixing portion 331, the second fixing portion 332, and the third fixing portion 333 each function to fix the position of the support portion 320 with respect to the footrest 130. The first fixing portion 331 and the second fixing portion 332 are provided at the bottom of the intermediate portion 323, for example. The third fixing portion 333 is disposed at the bottom of the first side portion 321, for example.

Fig. 15 is a front view showing a state in which a pair of foot treatment units 300 are attached to the footrest 130 in the embodiment of the present disclosure.

The support portion 320 is attached to the bottom wall 133 of the footrest 130, for example. In one example, the first side portion 321 is disposed to face the inner sidewall 131, the second side portion 322 is disposed to face the outer sidewall 132, and the middle portion 323 is disposed to face the back wall 134.

The first fixing portion 331, the second fixing portion 332, and the third fixing portion 333 are fixed to the bottom wall 133, for example. Thus, the first side portion 321 and the intermediate portion 323 are not easily displaced with respect to the footrest 130. On the other hand, the second side portion 322 is not fixed to any portion of the footrest 130, and can be displaced with respect to the footrest 130.

In the case where a strong force is applied to the ankle located on the outer side of the foot and the bones around it, the user tends to feel uncomfortable. This is related to the following: the ankle and its surrounding bones on the lateral side of the foot are prone to pain.

In the example of the present disclosure, since the second side portion 322 is displaceable with respect to the footrest 130, even if the second treatment member 312 comes into contact with the foot bone, the foot moves in response to pain or the like, and thus the position of the second treatment member 312 is likely to be displaced from the foot bone. Therefore, the ankle and the bones around it are not easily strongly contacted with the second treatment member 312, and the fear that the user feels uncomfortable can be reduced.

The support portion 320 is provided on the footrest 130 such that the first side portion 321 overlaps the inner leg airbag 141 and the second side portion 322 overlaps the outer leg airbag 142, for example. That is, the first treatment member 311 and the second treatment member 312 are pressed to the periphery of the ankle by at least the forces of the two balloons. In the example shown in fig. 15, a part of the first side portion 321 overlaps the inner airbag 141, and a part of the second side portion 322 overlaps the outer airbag 142. Therefore, stronger force can be applied to the peripheries of the ankles on both sides of the foot by the first treatment member 311 and the second treatment member 312, and massage of various strengths can be provided to the peripheries of the ankles by the combination of the inflated airbags.

The support portion 320 is attached to the footrest 130 so that the first treatment member 311 and the second treatment member 312 face each other. Air is supplied from the air pump 340 (see fig. 14) to the support portion 320 through the air supply port 323B, and the first side portion 321 and the second side portion 322 expand, whereby the first treatment member 311 and the second treatment member 312 approach each other. Thus, the first treatment member 311 and the second treatment member 312 are pressed to the periphery of the ankle.

Fig. 16 and 17 are views for explaining the relationship between the first treatment member 311 and the second treatment member 312 and the periphery of the ankle when the foot is placed on the footrest 130 in the embodiment of the present disclosure.

As shown in fig. 16, the first treatment applying member 311 is in contact with the periphery of the ankle located at the inner side of the foot. Specifically, the first treatment member 311 is in contact with the water spring point FS located at the periphery of the ankle of the inner side of the foot. Therefore, the circumference of the ankle including the spa FS is massaged by the first treatment member 311 by the expansion of the first side portion 321 (refer to fig. 14).

By massaging the spa points FS around the ankle, a more desirable massage feeling can be given to the ankle located on the inner side of the foot. Therefore, by massaging the spa FS with the first treatment member 311, a more desirable massage feeling can be given to the periphery of the ankle located on the inner side of the foot.

In addition, as shown in fig. 17, the second treatment applying member 312 is in contact with the periphery of the ankle located on the outer side of the foot. Specifically, the second treatment member 312 is in contact with the peripheral temple FB and the lymph node FL at the periphery of the lateral ankle of the foot. Thus, by the expansion of the second lateral portion 322 (refer to fig. 14), the circumference of the ankle including the temple point FB and the lymph node FL is massaged by the second treatment member 312.

When at least one of the peripheral acupoint "pu" FB and the lymph node FL around the ankle is massaged, a more desirable massage feeling can be given to the periphery of the ankle located on the outer side of the foot. Therefore, by massaging the peripheral acupoint FB and the lymph node FL with the second treatment member 312, a more desirable massage feeling can be given to the periphery of the ankle located on the outer side of the foot.

In the second example, the relative driving unit 243 is configured to: when the second protrusion 223 of the first treatment applying part 220 is closest to the second treatment applying part 230 in the front-rear direction of the foot, the second treatment applying part 230 is farthest from the rotating roller 221. In the third example, the relative driving unit 243 is configured to: when the curved surface portion 224 is closest to the second treatment site 230 in the front-rear direction of the foot, the second treatment site 230 is farthest from the rotating roller 221. In the fourth example, the relative driving unit 243 is configured to: when the second treatment unit 230 is moved backward in the front-rear direction of the foot, the sole of the foot comes into contact with at least one of the first convex portion 222 and the second convex portion 223.

The sole treatment block 200 according to the modification may be configured to omit the counter drive unit 243. According to this modification, the second treatment unit 230 is driven by a different driving unit from the driving unit 240, or the second treatment unit 230 may be fixed to the footrest 130 or the like.

The first treatment portion 220 and the second treatment portion 230 of the modification are provided on the footrest 130 such that the positions of the distal ends of the first convex portion 222 and the second convex portion 223 of the first treatment portion 220 when the distal ends are in contact with the sole are lower than the positions of the distal ends of the first convex portion 231, the second convex portion 232, and the third convex portion 233 of the second treatment portion 230 when the distal ends are in contact with the sole, or at substantially the same height.

The first convex portions 222 and the second convex portions 223 of the modification are substantially the same in position in the axial direction of the rotating roller 221.

The first convex portion 222 of the modification has a different structure on one side surface and the other side surface. In one example, the number of ribs provided on one side surface of the first projection 222 is different from the number of ribs provided on the other side surface. The same applies to the second convex portion 223.

In the first convex portion 222 of the modification, the second rib 222B may be omitted. According to this modification, the plurality of first ribs 222A are provided on the side surfaces of the first convex portions 222 so as to form a rib space 222C having a size that does not allow toes to enter.

The shape of the first rib 222A can be arbitrarily changed. In one example, the first rib 222A has a linear shape extending from one portion of the inner peripheral surface of the first convex portion 222 to another portion.

Whether or not the rib space 222C having a size that does not allow toes to enter is formed on the side surface of the first convex portion 222 can be arbitrarily changed. In one example, the rib space 222C is the size into which toes may enter. The same applies to the rib space 223B of the second convex portion 223.

The relationship between the first distance CH1 and the second distance CH2 can be changed arbitrarily. In the first example, the first distance CH1 is shorter than the second distance CH 2. In a second example, the first distance CH1 has substantially the same length as the second distance CH 2.

The second convex portion 223 of the modification includes one or more ribs having substantially the same structure as the second rib 222B of the first convex portion 222 in addition to the rib 223A, or includes one or more ribs having substantially the same structure as the second rib 222B in place of the rib 223A.
