In the present embodiment, the left and right foot portions FL and FR can be moved from the front to the rear and fitted into the left and right treatment recesses 4L and 4R. Further, an inner lining material (not shown) is provided inside the treatment recesses 4L and 4R.

[0029] As shown in FIGS. 1 to 3, massage mechanisms 2 for kneading and massaging the left and right foot portions FL and FR from the side and pressing and massaging the soles UL and UR (the insteps AL and AR) are provided on the lower sides of the left and right treatment recesses 4L and 4R. Further, in the case of the present embodiment, upper massage mechanisms for massaging the left and right shins from the side are provided on the upper sides of the left and right treatment recesses 4L and 4R.

[0030] As shown in FIG. 1, a plurality of support members 5a and 5b are provided upward on the bottom plate member 3a (the bottom surface inside the case body 3). The support members 5a and 5b support the massage mechanism 2 from below. Support members 5a for rotatably supporting the ends of the rotating shafts 7 provided in the massage mechanism 2 are provided at both ends in the left-right direction of the bottom surface inside the case body 3.

[0031] Also, one support member 5b for rotatably supporting the middle portion in the longitudinal direction of the rotating shaft 7 is provided between the pair of left and right support members 5a. A gear case of the drive unit 8 is attached above this support member 5b. That is, the two support members 5a, 5a and the support member 5b are provided on the bottom plate member 3a (the bottom surface inside the case body 3) at substantially equal intervals in the left-right direction.

[0032] As shown in FIGS. 1 to 5 and the like, the lower limb massager 1 of the present embodiment includes a massage mechanism 2 that massages the left and right feet F, the soles U, and the like.

[0033] The massage mechanism 2 of the present embodiment includes a left massage unit 6L that massages the left foot FL, the sole UL, and the like, a right massage unit 6R that massages the right foot FR, the sole UR, and the like, a rotating shaft 7 provided so as to penetrate the proximal ends of the left massage unit 6L and the right massage unit 6R, and a drive unit 8 that rotationally drives the rotating shaft.

[0034] The drive unit 8 rotationally drives the rotating shaft 7 to operate the left massage unit 6L and the right massage unit 6R. The drive unit 8 includes a drive motor that generates a rotational driving force and a gear case that decelerates the rotational driving force to a predetermined speed. The gear case is supported by the support member 5b.

[0035] The rotating shaft 7 is provided on the bottom plate member 3a (the bottom surface in the case body 3) so that the axis is horizontal and faces the left and right directions. The rotating shaft 7 is rotatably supported by three support members 5a and 5b via bearings.

[0036] The rotating shaft 7 is provided so as to penetrate, in the left and right directions, the proximal ends of the pair of left and right massage members 9L and 10L (left massage unit 6L) and the proximal ends of the pair of left and right massage members 9R and 10R (right massage unit 6R).

[0037] The rotating shaft 7 transmits the power of the kneading massage to the pair of left and right left massage members 9L and 10L (left massage unit 6L) and the pair of left and right right massage members 9R and 10R (right massage unit 6R) described later. In addition, a pair of sole pressing members 11L and 11R (details will be described later) are rotatably attached to the rotating shaft 7.

[0038] The present invention relates to a sole pressing member 11 provided in a lower limb massager 1 having a pair of left and right massage members 9 and 10 that sandwich the foot F and perform kneading massage, and a rotating shaft 7 whose axis is oriented in the left-right direction and penetrates the proximal ends of the pair of massage members 9 and 10.

[0039] The sole pressing member 11 of the present invention is a roller body (cylindrical body) whose axis is oriented in the left-right direction and is provided in a lying-down state. The sole pressing member 11, which is this roller body, has a diameter-expanded portion 26 having a shape that expands toward at least one end (the thumb side of the foot F).

[0040] The edge 24 of the diameter-expanded portion 26 is provided adjacent to the side wall of the massage member 9. The diameter-expanded portion 26 is provided with acupressure protrusions 28 that perform pressing massage on the sole U.

[0041] The acupressure protrusions 28 extend in a direction away from the massage member 9 along the left-right direction, are connected from the diameter-expanded portion 26, and extend toward the other end 25 of the sole pressing member 11. [Left massage part] Regarding the characteristic configuration of the sole pressing member 11 provided in the lower limb massager 1 of the present invention, an explanation will be given by focusing on the left massage part 6L.

[0042] As shown in FIG. 2 and the like, the left massage part 6L has a pair of left and right massage members 9L and 10L that sandwich the left foot FL constituting the lower limb and perform kneading massage, and a sole pressing member 11L that is disposed between the pair of left and right massage members 9L and 10L and is attached so as to rotate around the rotating shaft 7.

[0043] The left massage members 9L and 10L of the present embodiment are plate-shaped kneading massage members 9L and 10L. The left massage members 9L and 10L are formed in a curved shape that wraps around so as to follow the shape of the left foot part FL such as the toe tip, instep, ankle, and heel. These left massage members 9L and 10L are formed in a shape that wraps around the left foot part FL and are provided facing each other.

[0044] The left inner massage member 9L is provided on the inner side (thumb and ball of the foot AL side) of the left foot part FL. The left inner massage member 9L is a plate-shaped member provided above the rotation shaft 7 and protruding in the front-rear direction respectively. Also, the left inner massage member 9L has a shape that slopes upward from the front part (tip part) toward the rear part.

[0045] The left inner massage member 9L is provided on the inner side (thumb and ball of the foot AL side) of the left foot part FL and has a base left inner kneading plate member 12L and a cushion material 13L attached so as to overlap on the inner side (the side that contacts the inner side of the left foot part FL) of the left inner kneading plate member 12L.

[0046] The left inner kneading plate member 12L is a plate member having a shape along the left foot part FL. The cushion material 13L is deformable along the shape of the left foot part FL (thumb and ball of the foot AL side) so that a comfortable massage can be received.

[0047] The left outer massage member 10L is provided on the outer side (little finger side) of the left foot part FL. The left outer massage member 10L is a plate-shaped member provided above the rotation shaft 7 and protruding in the front-rear direction respectively. Also, the left outer massage member 10L has a shape that slopes upward from the front part (tip part) toward the rear part.

[0048] The left outer massage member 10L is provided on the outer side (little finger side) of the left foot part FL and has a base left outer kneading plate member 14L and a cushion material 15L attached so as to overlap on the inner side (the side that contacts the outer side of the left foot part FL) of the left outer kneading plate member 14L.

[0049] The left outer kneading plate member 14L is a plate member having a shape along the left foot part FL. The cushioning material 15L is deformable along the shape of the left foot part FL (left outer side) so that a comfortable massage can be received.

[0050] A pair of left massage members 9L and 10L (left kneading plate parts 9L and 10L) impart a kneading massage operation of sandwiching and pressing the left foot part FL from the tip of the foot to the heel from the inside and the outside.

[0051] As shown in FIGS. 1 to 3 and the like, the middle part in the longitudinal direction of the left inner massage member 9L is the base end and a left inner conversion part 16L is provided at the base end thereof. The left inner conversion part 16L converts the rotational driving force of the rotary shaft 7 into the swinging motion of the left inner massage member 9L.

[0052] The left inner conversion part 16L has a left inner rotary boss part 18L that rotates integrally with the rotary shaft 7, a left inner annular fitting part 19L that is provided at the base end of the left inner massage member 9L and fits into the outer peripheral edge of the left inner rotary boss part 18L, and a left inner regulating part 20L that regulates the co-rotation of the left inner massage member 9L with the rotary shaft 7.

[0053] The left inner rotary boss part 18L is provided with a cam surface inclined with respect to the rotary shaft 7 on the outer peripheral surface. The left inner annular fitting part 19L externally fits the cam surface of the left inner rotary boss part 18L in a relatively rotatable state. As the left inner annular fitting part 19L slides on the inclined cam surface when the left inner rotary boss part 18L rotates, the left inner massage member 9L performs a swinging motion with respect to the axis of the rotary shaft 7.

[0054] The left inner regulating part 20L regulates the circumferential rotation of the left inner annular fitting part 19L with respect to the left inner rotary boss part 18L. The left inner regulating part 20L has a pin member provided on the base end side of the left inner massage member 9L and a regulating groove into which the pin member slidably fits. The regulating groove is provided in the bottom plate member 3a at a position facing the pin member, although not shown in the drawings.

[0055] The lower end side of the middle part in the longitudinal direction (front-rear direction) of the left outer massage member 10L is taken as the base end, and a left outer conversion part 17L is provided at the base end. The left outer conversion part 17L converts the rotational driving force of the rotary shaft 7 into the swinging motion of the left outer massage member 10L.

[0056] This left outer conversion part 17L is arranged at a position facing the left inner conversion part 16L. That is, the left inner and outer conversion parts 16L and 17L are arranged side by side in the left-right direction.

[0057] The left outer conversion part 17L has a left outer rotary boss part 21L that rotates integrally with the rotary shaft 7, a left outer annular fitting part 22L that is provided at the base end of the left outer massage member 10L and fits into the outer peripheral edge of the left outer rotary boss part 21L, and a left outer restricting part 23L that restricts the co-rotation of the left outer massage member 10L with the rotary shaft 7.

[0058] The above-mentioned left inner and outer conversion parts 16L and 17L are inclined with respect to each other such that the inclinations of the left inner and outer rotary boss parts 18L and 21L are opposite to each other (become V-shaped or inverted V-shaped in a front view by rotation). With this arrangement, the left inner and outer conversion parts 16L and 17L convert the rotational driving force of the rotary shaft 7 into the approaching and separating movements of the left inner and outer massage members 9L and 10L.

[0059] Specifically, the left inner and outer conversion parts 16L and 17L convert the rotational driving force of the rotary shaft 7 into the swinging motion of the left inner and outer massage members 9L and 10L by the inclined rotation of the left inner and outer rotary boss parts 18L and 21L. The tip ends of the left inner and outer massage members 9L and 10L will approach each other and fall down. Thereafter, the tip ends of the left inner and outer massage members 9L and 10L will separate from each other, and the middle parts in the longitudinal direction will approach each other and fall down. Finally, the middle parts in the longitudinal direction of the left inner and outer massage members 9L and 10L will separate from each other, and the rear ends will approach each other and fall down.

[0060] In this way, the rotational driving force of the rotating shaft 7 is converted into a swinging motion by the left inner and outer conversion parts 16L and 17L, and the left inner and outer massage members 9L and 10L are sequentially brought closer and fall down from the tip end toward the rear end, so as to sandwich and press against the left foot part FL to apply a kneading massage.

[0061] As shown in FIGS. 1 to 5, further, the left massage part 6L of the present embodiment is provided with a sole pressing member 11L that applies a pressing massage operation for pressing from below against the longitudinal center (arch AL) of the sole UL of the left foot part FL.

[0062] The sole pressing member 11L of the present embodiment is a roller body (rotating body, cylindrical body) whose axis is oriented in the left-right direction and is provided in a horizontally lying state. The sole massage roller 11L (sole pressing member 11L) of the present embodiment is disposed between the left inner and outer massage members 9L and 10L. The left sole massage roller 11L is attached to the left side of the rotating shaft 7 so as to be paired with the right sole massage roller 11R.

[0063] This sole massage roller 11L is rotatably attached to the rotating shaft 7 in a skewered manner. In the present embodiment, the axis of the sole massage roller 11L and the axis of the rotating shaft 7 are the same axis. Note that the sole massage roller 11L may be configured to be attached eccentrically with respect to the axis of the rotating shaft 7.

[0064] Further, the sole massage roller 11L of the present embodiment has a width that can support the arch AL of the sole UL of the left foot part FL in a surface contact state. When the left inner and outer massage members 9L and 10L repeat the swinging motion, the sole massage roller 11L rotates in conjunction with the swinging motion and applies a pressing massage to the arch AL (sole UL).

[0065] As shown in FIGS. 2 to 5, the sole massage roller 11L (sole pressing member 11L) of the present embodiment is a rotating body that is long about the width of the left foot part FL.

[0066] The sole massage roller 11L has a diameter-expanding portion 26L that extends from the middle part in the left-right direction (longitudinal direction) toward one end. One end is the portion from the start of the expansion of the first diameter-expanding portion 26L to the edge 24L (the right edge 24L (inner edge 24L) of the sole massage roller 11L).

[0067] Specifically, the first diameter-expanding portion 26L of the present embodiment is formed in a shape that gradually expands from the middle part in the longitudinal direction of the sole massage roller 11L toward the edge 24L on the side (inner side) corresponding to the instep AL of the left foot portion FL (a trumpet shape opening to the right). The first diameter-expanding portion 26L has a shape in which the diameter gradually expands toward the left inner massage member 9L side.

[0068] Also, the sole massage roller 11L of the present embodiment has a first diameter-expanding portion 26L that extends toward one end (inner side) and a second diameter-expanding portion 27L that extends toward the other end (outer side).

[0069] The other end is the portion from the start of the expansion of the second diameter-expanding portion 27L to the edge 25L (the left edge 25L (outer edge 25L) of the sole massage roller 11L).

[0070] The second diameter-expanding portion 27L of the present embodiment is formed in a shape that gradually expands from the middle part in the longitudinal direction of the sole massage roller 11L toward the edge 25L on the side (outer side) corresponding to the outer side (little finger side) of the left foot portion FL (a trumpet shape opening to the left). The second diameter-expanding portion 27L has a shape in which the diameter gradually expands toward the left outer massage member 10L side.

[0071] The sole massage roller 11L of the present embodiment is provided with a pair of a first diameter-expanding portion 26L that extends from the middle part in the longitudinal direction toward the right edge 24L and a second diameter-expanding portion 27L that extends from the middle part in the longitudinal direction toward the left edge 25L.

[0072] That is, the sole massage roller 11L of the present embodiment has a first diameter-expanded portion 26L and a second diameter-expanded portion 27L provided in a pair, and thus is formed in a drum shape with a constriction in the middle in the left-right direction.

[0073] In this way, by providing a pair of diameter-expanded portions 26L and 27L toward the left and right edges 24L and 25L of the sole massage roller 11L respectively (the sole massage roller 11L is drum-shaped), the left foot portion FL is positioned at the center in the left-right direction of the sole massage roller 11L without swaying left and right, and can surely receive massage.

[0074] The edge 24L of the first diameter-expanded portion 26L on the left inner side (the right edge 24L of the sole massage roller 11L) is provided adjacent to the side wall of the left inner massage member 9L (the left inner annular fitting portion 19L) among the pair of massage members 9L and 10L.

[0075] Here, the "adjacent" means that the edge 24L of the first diameter-expanded portion 26L slidably abuts against the left inner massage member 9L, or there is a gap of several millimeters (about 0.1 mm to 3 mm) between the edge 24L of the first diameter-expanded portion 26L and the left inner massage member 9L.

[0076] Further, in the present embodiment, the edge 25L of the second diameter-expanded portion 27L on the left outer side (the left edge 25L (outer edge 25L) of the sole massage roller 11L) is provided adjacent to the side wall of the left outer massage member 10L (the left outer annular fitting portion 22L).

[0077] Here, the above "adjacent" means that the edge 25L of the second diameter-expanded portion 27L slidably abuts against the left outer massage member 10L, or there is a gap of several millimeters (about 0.1 mm to 3 mm) between the edge 25L of the second diameter-expanded portion 27L and the left outer massage member 10L.

[0078] As shown in FIG. 3, in the present embodiment, the edge 24L (the most enlarged part) of the first enlarged diameter portion 26L is flush with the first boss pressing protrusion 28L. The edge 24L (radius) of the first enlarged diameter portion 26L is the same as (flush with) the height of the first boss pressing protrusion 28L, or is larger than the first boss pressing protrusion 28L.

[0079] On the outer peripheral surface of the sole massage roller 11L of the present embodiment, boss pressing protrusions 28L, 29L, and 30L facing radially outward are provided at intervals in the circumferential direction and the axial direction of the rotation shaft 7. The boss pressing protrusions 28L, 29L, and 30L of the present embodiment are provided in a plurality of different shapes.

[0080] As shown in FIGS. 2 to 5, the first enlarged diameter portion 26L is provided with a first boss pressing protrusion 28L that performs a pressing massage on the sole UL (arch AL) of the left foot portion FL.

[0081] The first boss pressing protrusion 28L is in a direction of separating from the left inner massage member 9L along the left - right direction, is connected to the first enlarged diameter portion 26L, and extends toward the other end (outer side) of the sole massage roller 11L.

[0082] As shown in FIG. 2, the first boss pressing protrusion 28L extends leftward (in a direction opposite to the left inner massage member 9L) from the edge 24L of the first enlarged diameter portion 26L along the axial direction of the rotation shaft 7.

[0083] The first boss pressing protrusion 28L has a predetermined thickness and is provided at a position corresponding to the arch AL side (inner side of the sole UL) of the left foot portion FL. Further, the first boss pressing protrusion 28L is rounded with an R (round) at the corners so as to fit the sole UL and the arch AL.

[0084] The height of the first acupoint pressing protrusion 28L is preferably the same as (flush with) the radius at the position of the most enlarged edge 24L (the right edge 24L of the sole massage roller 11L) in the first enlarged diameter portion 26L, or lower than that radius. That is, the first acupoint pressing protrusion 28L is preferably not larger than the edge 24L (the most enlarged portion) of the first enlarged diameter portion 26L.

[0085] As shown in FIG. 3, in the present embodiment, the first acupoint pressing protrusion 28L is flush with the edge 24L (the most enlarged portion) of the first enlarged diameter portion 26L. This first acupoint pressing protrusion 28L is provided so as to protrude leftward from the edge 24L (the right edge 24L of the sole massage roller 11L) of the first enlarged diameter portion 26L.

[0086] In this way, by providing the edge 24L of the first enlarged diameter portion 26L provided on the left sole massage roller 11L adjacent to the side wall of the left inner massage member 9L and making the height of the first acupoint pressing protrusion 28L up to the most enlarged radius at the edge 24L of the first enlarged diameter portion 26L, the gap between the left inner massage member 9L and the first acupoint pressing protrusion 28L is almost eliminated.

[0087] Thereby, it is possible to prevent the left inner side (the instep AL side) of the left foot portion FL from being caught between the left inner massage member 9L and the first acupoint pressing protrusion 28L during the massage operation.

[0088] The first acupoint pressing protrusion 28L of the present embodiment extends leftward from the edge 24L of the first enlarged diameter portion 26L in the axial direction of the rotation shaft 7, and has a horizontal portion 31L which is a side in the axial direction of the rotation shaft 7, a vertical portion 32L which is a side perpendicular to the axial direction of the rotation shaft 7 (a rising portion facing the intersecting direction with respect to the left - right direction), and a corner portion 33L where the horizontal portion 31L switches to the vertical portion 32L. Note that for the vertical portion 32L, it may be a side perpendicular to the axial direction of the rotation shaft 7, or may be a side facing the intersecting direction (for example, an inclined side like a trapezoid, a rising portion 32L).

[0089] The first acupressure projection 28L has a substantially triangular plane 34L surrounded by a horizontal portion 31L, a vertical portion 32L, a corner portion 33L, and an inclined side of the first enlarged diameter portion 26L, and is a projection formed wide in the axial direction of the rotation shaft 7 and in the left direction.

[0090] As shown in FIG. 3, the first acupressure projection 28L of the present embodiment is formed in a shape that protrudes greatly leftward from the edge 24L of the first enlarged diameter portion 26L, and is a projection extending in a horizontally long shape so as to include the plane 34L. A pair of the first acupressure projections 28L are provided with the rotation shaft 7 interposed therebetween.

[0091] Returning to FIG. 2, the horizontal portion 31L faces leftward from the edge 24L of the first enlarged diameter portion 26L and extends long in the axial direction of the rotation shaft 7.

[0092] As shown in FIG. 3, the horizontal portion 31L is at the same position as the height of the edge 24L (the portion with the largest spread) of the first enlarged diameter portion 26L. That is, the horizontal portion 31L is a long side linearly extending leftward from the edge 24L of the first enlarged diameter portion 26L (the right edge 24L of the sole massage roller 11L) in the axial direction of the rotation shaft 7.

[0093] Thus, since the horizontal portion 31L is a side extending long leftward from the edge 24L of the first enlarged diameter portion 26L (the right edge 24L of the sole massage roller 11L), it can support the sole UL (the instep AL) of the left foot portion FL in a line contact state or a surface contact state.

[0094] The vertical portion 32L (rising portion 32L) is a side extending vertically from the end of the horizontal portion 31L. The corner portion 33L is provided at the tip of the horizontal portion 31L. From this corner portion 33L, the vertical portion 32L hangs down in the axial direction of the rotation shaft 7. This corner portion 33L is shaped so as to be able to exert a strong pushing force on the instep AL (the sole UL). On the other hand, the corner portion 33L is rounded with an R (radius) so as not to bite too deeply into the instep AL (the sole UL).

[0095] Note that the horizontal portion 31L and the corner portion 33L may be at a position lower than the horizontal extension line of the edge 24L of the first enlarged diameter portion 26L.

[0096] Thus, since the first acupressure protrusion 28L has the horizontal portion 31L, the vertical portion 32L, and the corner portion 33L (as shown in FIG. 3, it has a horizontally long shape), the left foot portion FL can be stably supported by the horizontal portion 31L, and it is possible to prevent the left foot portion FL from sinking. Further, by providing the corner portion 33L, it is possible to effectively perform a pressing massage that strongly presses against the heel AL (the sole UL).

[0097] That is, since the first acupressure protrusion 28L of the present embodiment is formed in a horizontally long shape and a pair of them are provided at equal intervals around the axis, while stably supporting the left foot portion FL, a pressing massage that is strongly pressed can be applied to the heel AL of the left foot portion FL at a predetermined rhythm (180° interval).

[0098] Further, when the acupressure protrusion is slender and convex, that is, rod-shaped, a pressing massage that is too strong for the sole may be performed. However, in the present embodiment, due to the first enlarged diameter portion 26L and the horizontally long first acupressure protrusion 28L provided on the first enlarged diameter portion 26L, it is possible to effectively apply a pressing massage to the sole UL (the heel AL).

[0099] Furthermore, with the shape of the first acupressure protrusion 28L of the present embodiment, since there is no sharp portion, for example, even if a thread fraying or the like occurs in the cloth cover (inner lining) of the treatment recess 4L, the frayed thread will not be caught by being wound around, and it is possible to avoid the possibility of the cloth cover being broken or deteriorated.

[0100] A second acupressure protrusion 29L is provided on the second enlarged diameter portion 27L. This second acupressure protrusion 29L is provided at a position corresponding to the outside of the sole UL (the little finger side of the left foot portion FL). The second acupressure protrusion 29L is provided facing the first acupressure protrusion 28L in the axial direction of the rotation shaft 7.

[0101] Further, the second acupoint pressing protrusion 29L is shaped to protrude slightly outward in the radial direction, and a pair of them are provided with the rotation axis 7 therebetween. The second acupoint pressing protrusion 29L can apply a pressing massage that is gently finger-pressed to the outer side of the foot at a predetermined rhythm (180° phase interval).

[0102] Regarding the sizes of the acupoint pressing protrusions 28L and 29L in the present embodiment, the first acupoint pressing protrusion 28L on the inner side (arch AL side) of the left foot part FL is large. On the other hand, the second acupoint pressing protrusion 29L on the outer side (little finger side) of the left foot part FL is smaller than the first acupoint pressing protrusion 28L.

[0103] Further, the second acupoint pressing protrusion 29L may have the same shape as the first acupoint pressing protrusion 28L, and may be provided on the second diameter-expanded part 27L facing the first acupoint pressing protrusion 28L. That is, the first acupoint pressing protrusion 28L may be provided on each of the left and right diameter-expanded parts 26L and 27L so as to face each other in the axial direction of the rotation axis 7.

[0104] Since the two acupoint pressing protrusions 28L and 29L face each other, a pressing massage that is finger-pressed can be performed on the arch AL (thumb side) and the outer side of the foot (little finger side) opposite to the arch AL at the same timing (180° phase interval). Also, the left foot part FL can be placed against the central part of the foot sole massage roller 11L.

[0105] The third acupoint pressing protrusion 30L is provided at the center of the foot sole massage roller 11L corresponding to the sole UL of the left foot part FL. The third acupoint pressing protrusion 30L is shaped to protrude largely outward in the radial direction and a pair of them are provided with the rotation axis 7 therebetween. The size, shape, arrangement, etc. of the third acupoint pressing protrusion 30L can be arbitrarily set. The third acupoint pressing protrusion 30L can apply a pressing massage that is strongly finger-pressed to the sole UL (such as the center of the arch) at a predetermined rhythm (180° interval).

[0106] When the sole massage roller 11L provided with a plurality of acupressure protrusions 28L, 29L, 30L having different shapes rotates, an effective pressing massage can be applied to the sole UL and the instep AL of the left foot part FL.

[0107] As described above, according to the sole massage roller 11L provided in the lower limb massager 1 of the present invention, the first diameter-expanded part 26L and the second diameter-expanded part 27L having a shape that expands toward the edge 24L at one end are provided in a pair to form a drum-shaped roller body, and the first diameter-expanded part 26L is provided with a horizontally long acupressure protrusion 28L composed of a horizontal part 31L, a vertical part 32L, and a corner part 33L. Thus, the left foot part FL can be stably supported without being displaced left and right, and while preventing excessive pushing into the sole UL (instep AL), an effective pressing massage can be performed by moderately pushing into the sole UL (instep AL). [Right massage part] Next, the right massage part 6R will be described. Since the right massage part 6R has the same configuration as the left massage part 6L, it will be described focusing on the main points.

[0108] The right massage part 6R includes a pair of left and right massage members 9R, 10R that sandwich the right foot part FR constituting the lower limb and perform kneading massage, and a sole pressing member 11R that is disposed between the pair of left and right massage members 9R, 10R and is attached so as to rotate around the rotation shaft 7.

[0109] The right massage members 9R, 10R of the present embodiment are plate-shaped kneading massage members 9R, 10R. The right massage members 9R, 10R are formed in a curved shape that wraps around along the shape of the right foot part FR such as the toe - instep - ankle - heel. These right massage members 9R, 10R are formed in a shape that wraps around the right foot part FR and are provided facing each other.

[0110] The right inner massage member 9R is provided on the inner side of the right foot part FR (the side of the thumb and the ball of the foot AR), and includes a right inner rubbing plate member 12R serving as a base, and a cushioning material 13R attached so as to overlap on the inner side of the right inner rubbing plate member 12R (the side that contacts the inner side of the right foot part FR).

[0111] The right outer massage member 10R is provided on the outer side of the right foot part FR (the little finger side), and includes a left outer rubbing plate member 14R serving as a base, and a cushioning material 15R attached so as to overlap on the inner side of the right outer rubbing plate member 14R (the side that contacts the outer side of the right foot part FR).

[0112] A pair of right massage members 9R, 10R (right rubbing plate parts 9R, 10R) apply a rubbing massage operation of sandwiching the right foot part FR from the tip of the toe to the heel so as to push from the inner and outer sides.

[0113] As shown in FIGS. 1 to 3 etc., the middle part in the longitudinal direction of the right inner massage member 9R is the base end, and a right inner conversion part 16R is provided at the base end. The right inner conversion part 16R converts the rotational driving force of the rotating shaft 7 into a swinging motion of the right inner massage member 9R.

[0114] The middle part in the longitudinal direction of the right outer massage member 10R is the base end, and a right outer conversion part 17R is provided at the base end. The right outer conversion part 17R converts the rotational driving force of the rotating shaft 7 into a swinging motion of the right outer massage member 10R.

[0115] This right outer conversion part 17R is arranged at a position facing the right inner conversion part 16R. That is, the right inner and outer conversion parts 16R, 17R are arranged side by side in the left - right direction. The aforementioned right inner and outer conversion parts 16R, 17R are inclined with respect to each other such that their inclinations are opposite to each other (become V - shaped or inverted V - shaped by rotation). With this arrangement, the right inner and outer conversion parts 16R, 17R convert the rotational driving force of the rotating shaft 7 into a proximity - separation operation of the right inner and outer massage members 9R, 10R.

[0116] As shown in FIGS. 1 to 3, further, in the right massage part 6R of the present embodiment, a sole pressing member 11R that applies a pressing massage operation for pressing from below is provided with respect to the longitudinal center (arch AR) of the sole UR of the right foot part FR.

[0117] The sole pressing member 11R of the present embodiment is a roller body (rotating body) whose axis is oriented in the left-right direction and is provided in a lying-down state. The sole massage roller 11R of the present embodiment is disposed between the right inner and outer massage members 9R and 10R.

[0118] The right sole massage roller 11R is attached to the right side of the rotary shaft 7 so as to be paired with the left sole massage roller 11L. The right sole massage roller 11R has a configuration obtained by inverting and mirroring the left sole massage roller 11L.

[0119] This sole massage roller 11R (sole pressing member 11R) is rotatably attached to the rotary shaft 7 in a skewered state. In the present embodiment, the axis of the sole massage roller 11R and the axis of the rotary shaft 7 are the same axis. Note that the sole massage roller 11R may be configured to be attached eccentrically with respect to the axis of the rotary shaft 7.

[0120] Further, the sole massage roller 11R of the present embodiment has a width that can support the arch AR of the sole UR of the right foot part FR in a surface contact state. When the right inner and outer massage members 9R and 10R repeat the swinging motion, the sole massage roller 11R rotates in conjunction with the swinging motion and applies a pressing massage to the arch AR (sole UR).

[0121] As shown in FIGS. 2 and 3, the sole massage roller 11R of the present embodiment is a rotating body that is about as long as the width of the right foot part FR.

[0122] The sole massage roller 11R, which is a rotating body, has a diameter-increasing portion 26R that extends from the middle part in the left-right direction (longitudinal direction) toward one end. Note that one end is the portion from the start of the spread of the first diameter-increasing portion 26R to the edge 24R (the right edge 24R (inner edge 24R) of the sole massage roller 11R).

[0123] Specifically, the first diameter-increasing portion 26R of the present embodiment is formed in a shape that gradually expands from the middle part in the longitudinal direction of the sole massage roller 11R toward the edge 24R on the side (inner side) corresponding to the instep AR of the right foot portion FR (a trumpet shape opening to the left). The first diameter-increasing portion 26R has a shape in which the diameter gradually increases toward the right inner massage member 9R side.

[0124] Also, the sole massage roller 11R of the present embodiment has a first diameter-increasing portion 26R that extends toward one end (inner side) and a second diameter-increasing portion 27R that extends toward the other end (outer side).

[0125] Note that the other end is the portion from the start of the spread of the second diameter-increasing portion 27R to the edge 25R (the right edge 25R (outer edge 25R) of the sole massage roller 11R).

[0126] The second diameter-increasing portion 27R of the present embodiment is formed in a shape that gradually expands from the middle part in the longitudinal direction of the sole massage roller 11R toward the edge 25R on the side (outer side) corresponding to the outer side (little finger side) of the right foot portion FR (a trumpet shape opening to the right). The second diameter-increasing portion 27R has a shape in which the diameter gradually increases toward the left outer massage member 10R side.

[0127] The sole massage roller 11R of the present embodiment is provided with a pair of a first diameter-increasing portion 26R that extends from the middle part in the longitudinal direction toward the left edge 24R and a second diameter-increasing portion 27R that extends from the middle part in the longitudinal direction toward the right edge 25R.

[0128] That is, the sole massage roller 11R of the present embodiment has a first diameter-expanded portion 26R and a second diameter-expanded portion 27R provided in a pair, and thus is formed in a drum shape with a constriction in the middle in the left-right direction.

[0129] In this way, by providing a pair of diameter-expanded portions 26R and 27R toward the left and right edges 24R and 25R of the sole massage roller 11R respectively (the sole massage roller 11R is in a drum shape), the right foot part FR is positioned at the center of the sole massage roller 11R without swaying left and right, and can surely receive a massage.

[0130] The edge 24R of the first diameter-expanded portion 26R on the right inner side (the left edge 24R of the sole massage roller 11R) is provided adjacent to the side wall of the right inner massage member 9R (the right inner annular fitting portion 19R) among the pair of massage members 9R and 10R.

[0131] Note that the above-mentioned "adjacent" includes that the edge 24R of the first diameter-expanded portion 26R slidably abuts against the right inner massage member 9R, or there is a gap of several millimeters (about 0.1 mm to 3 mm) between the edge 24R of the first diameter-expanded portion 26R and the right inner massage member 9R.

[0132] Also, in the present embodiment, the edge 25R of the second diameter-expanded portion 27R on the right outer side (the right edge 25R (outer edge 25R) of the sole massage roller 11R) is provided adjacent to the side wall of the right outer massage member 10R (the right outer annular fitting portion 22R).

[0133] Note that the above-mentioned "adjacent" includes that the edge 25R of the second diameter-expanded portion 27R slidably abuts against the right outer massage member 10R, or there is a gap of several millimeters (about 0.1 mm to 3 mm) between the edge 25R of the second diameter-expanded portion 27R and the right outer massage member 10R.

[0134] As shown in Fig. 3, in this embodiment, the edge 24R (the most enlarged part) of the first enlarged diameter portion 26R is flush with the first boss pressing protrusion 28R. The edge 24R (radius) of the first enlarged diameter portion 26R is preferably the same as (flush with) the height of the first boss pressing protrusion 28R or larger than the first boss pressing protrusion 28R.

[0135] On the outer peripheral surface of the sole massage roller 11R of this embodiment, boss pressing protrusions 28R, 29R, and 30R facing radially outward are provided at intervals in the circumferential direction and the axial direction of the rotation shaft 7. The boss pressing protrusions 28R, 29R, and 30R of this embodiment are provided in a plurality of different shapes.

[0136] As shown in Figs. 2 and 3, the first enlarged diameter portion 26R is provided with a first boss pressing protrusion 28R that performs a pressing massage on the sole UR (arch AR) of the right foot portion FR.

[0137] The first boss pressing protrusion 28R is in a direction of separating from the right inner massage member 9R along the left - right direction, is connected from the first enlarged diameter portion 26R, and extends toward the other end (right direction) of the sole massage roller 11R.

[0138] As shown in Fig. 2, the first boss pressing protrusion 28R extends in the right direction (opposite to the right inner massage member 9R) from the edge 24R of the first enlarged diameter portion 26R along the axial center direction of the rotation shaft 7.

[0139] The first boss pressing protrusion 28R has a predetermined thickness and is provided at a position corresponding to the inner side (arch AR side) of the sole UR of the right foot portion FR. Further, the first boss pressing protrusion 28R is rounded with an R (round) at the corners so as to fit the sole UR and the arch AR.

[0140] The height of the first acupressure protrusion 28R is preferably the same as (flush with) the radius at the position of the most expanded edge 24R (the right edge 24R of the sole massage roller 11R) in the first expanded diameter portion 26R, or lower than that radius. That is, the first acupressure protrusion 28R is preferably not larger than the edge 24R (the most expanded portion) of the first expanded diameter portion 26R.

[0141] As shown in FIG. 3, in the present embodiment, the first acupressure protrusion 28R is flush with the edge 24R (the most expanded portion) of the first expanded diameter portion 26R. This first acupressure protrusion 28R is provided so as to protrude rightward from the edge 24R (the right edge 24R of the sole massage roller 11R) of the first expanded diameter portion 26R.

[0142] In this way, by providing the edge 24R of the first expanded diameter portion 26R provided on the right sole massage roller 11R adjacent to the side wall of the right inner massage member 9R and making the height of the first acupressure protrusion 28R up to the most expanded radius at the edge 24R of the first expanded diameter portion 26R, the gap between the right inner massage member 9R and the first acupressure protrusion 28R is almost eliminated.

[0143] Thereby, it is possible to prevent the inside (ankle AR side) of the right foot part FR from being caught between the right inner massage member 9R and the first acupressure protrusion 28R during the massage operation.

[0144] The first acupressure protrusion 28R of the present embodiment extends rightward from the edge 24R of the first expanded diameter portion 26R in the axial direction of the rotation shaft 7, and has a horizontal portion 31R which is a side in the axial direction of the rotation shaft 7, a vertical portion 32R which is a side perpendicular to the axial direction of the rotation shaft 7, and a corner portion 33R where the horizontal portion 31R switches to the vertical portion 32R.

[0145] The first acupressure protrusion 28R has a substantially triangular plane 34R surrounded by the horizontal portion 31R, the vertical portion 32R, the corner portion 33R, and the inclined side of the first expanded diameter portion 26R, and is a wide protrusion in the axial direction of the rotation shaft 7 and rightward.

[0146] As shown in Fig. 3, the first indentation protrusion 28R of the present embodiment is formed in a shape that protrudes greatly rightward from the edge 24R of the first enlarged diameter portion 26R and is a protrusion extending in a horizontally long shape large enough to include a flat surface 34R. A pair of the first indentation protrusions 28R are provided with the rotation axis 7 therebetween. Returning to Fig. 2, the horizontal portion 31R faces rightward from the edge 24R of the first enlarged diameter portion 26R and extends long in the axial direction of the rotation axis 7.

[0147]

[0148] As shown in Fig. 3, the horizontal portion 31R is at the same position as the height of the edge 24R (the place with the largest spread) of the first enlarged diameter portion 26R. That is, the horizontal portion 31R is a long side linearly extending rightward from the edge 24R (the left edge 24R of the sole massage roller 11R) of the first enlarged diameter portion 26R in the axial direction of the rotation axis 7.

[0149] Thus, since the horizontal portion 31R is a side extending long rightward from the edge 24R (the left edge 24R of the sole massage roller 11R) of the first enlarged diameter portion 26R, it can support the sole UR (the instep AR) of the right foot portion FR in a surface contact state.

[0150] The vertical portion 32R is a side extending vertically from the end of the horizontal portion 31R. The corner portion 33R is provided at the tip of the horizontal portion 31R. From this corner portion 33R, the vertical portion 32R hangs down in the axial direction of the rotation axis 7. This corner portion 33R is shaped to be able to apply a strong pushing force to the instep AR (the sole UR). On the other hand, the corner portion 33R is rounded with an R (radius) so as not to dig too deeply into the instep AR (the sole UR).

[0151] Note that the horizontal portion 31R and the corner portion 33R may be at a position lower than the horizontal extension line of the edge 24R of the first enlarged diameter portion 26R in the left - right direction.

[0152] ​Thus, since the first acupressure protrusion 28R has the horizontal portion 31R, the vertical portion 32R, and the corner portion 33R (as shown in FIG. 3, it has a horizontally long shape), the right foot portion FR can be stably supported by the horizontal portion 31R, and it is possible to prevent the right foot portion FR from sinking. Further, by providing the corner portion 33R, it is possible to effectively perform a pressing massage that strongly presses against the ball AR (the sole UR).

[0153] That is, since the first acupressure protrusion 28R of the present embodiment is formed in a horizontally long shape and a pair of them are provided at equal intervals around the axis, while stably supporting the right foot portion FR, a pressing massage that is strongly pressed can be applied to the ball AR of the right foot portion FR at a predetermined rhythm (180° interval).

[0154] Further, when the acupressure protrusion is slender and convex, there has been a case where a pressing massage that is too strong for the sole is performed. However, in the present embodiment, due to the first enlarged diameter portion 26R and the first acupressure protrusion 28R having a horizontally long shape provided on the first enlarged diameter portion 26R, it is possible to effectively apply a pressing massage to the sole UR (the ball AR).

[0155] Furthermore, with the shape of the first acupressure protrusion 28R of the present embodiment, it will not get caught on the cloth cover (inner lining material) of the treatment recess 4R, and the thread waste of the cloth cover will not come out.

[0156] The second enlarged diameter portion 27R is provided with a second acupressure protrusion 29R. This second acupressure protrusion 29R is provided at a position corresponding to the outside of the sole UR (the little finger side of the right foot portion FR). The second acupressure protrusion 29R is provided facing the first acupressure protrusion 28R in the axial direction of the rotation axis 7.

[0157] Also, the second acupressure protrusion 29R has a shape that slightly protrudes in the radially outer direction, and a pair of them are provided with the rotation axis 7 interposed therebetween. The second acupressure protrusion 29R can apply a pressing massage that is weakly pressed to the outside of the foot at a predetermined rhythm (180° interval).

[0158] Regarding the sizes of the acupoint pressing protrusions 28R and 29R of the present embodiment, the first acupoint pressing protrusion 28R on the inner side (arch AR side) of the right foot part FR is large. On the other hand, the second acupoint pressing protrusion 29R on the outer side (little finger side) of the right foot part FR is smaller than the first acupoint pressing protrusion 28R.

[0159] Further, the second acupoint pressing protrusion 29R may have the same shape as the first acupoint pressing protrusion 28R and may be provided on the second diameter-expanded part 27R facing the first acupoint pressing protrusion 28R. That is, the first acupoint pressing protrusion 28R may be provided on each of the left and right diameter-expanded parts 26R and 27R so as to face each other in the axial direction of the rotation shaft 7.

[0160] Since the two acupoint pressing protrusions 28R and 29R face each other, acupressure such as pressing massage can be performed on the arch AR (thumb side) and the outer side of the foot (little finger side) opposite to the arch AR at the same timing. Also, the right foot part FR can be placed against the central part of the foot sole massage roller 11R.

[0161] The third acupoint pressing protrusion 30R is provided at the center of the sole UR of the right foot part FR. The third acupoint pressing protrusion 30R has a shape that protrudes greatly in the radially outward direction, and a pair of them are provided with the rotation shaft 7 interposed therebetween. Regarding the size, shape, arrangement, etc. of the third acupoint pressing protrusion 30R, they can be set arbitrarily. The third acupoint pressing protrusion 30R can apply a pressing massage that is strongly acupressed to the sole UR at a predetermined rhythm (at 180° intervals).

[0162] As described above, according to the sole massage roller 11R provided in the lower limb massager 1 of the present invention, the sole massage roller 11R provided between the pair of left and right massage means 9R and 10R is provided with a diameter-expanded portion 26R having a shape that expands toward the edge 24R at one end, and a horizontally long-shaped acupoint pressing projection 28R composed of a horizontal portion 31R, a vertical portion 32R, and a corner portion 33R. By providing a second diameter-expanded portion 27L to form a drum-shaped roller body, the right foot portion FR can be stably supported without being displaced left and right, and while preventing excessive pressing into the sole UR (arch AR), an effective pressing massage can be performed with appropriate pressing on the sole UR (arch AR).

[0163] It should be considered that all aspects of the embodiments disclosed this time are illustrative and not restrictive. In particular, in the embodiments disclosed this time, matters not explicitly stated, such as operating conditions, operation conditions, dimensions of components, weights, etc., do not deviate from the scope normally implemented by those skilled in the art, and those skilled in the art can easily assume matters that can be adopted.

[0164] Note that the shape of the massage members 9 and 10 (kneading plate portions 9 and 10) of the present embodiment, the inclination angle with respect to the rotation axis 7 of the massage members 9 and 10, the separation distance between the pair of massage members 9 and 10, etc. can be appropriately changed in view of the treatment range. Also, for the massage members 9 and 10, an airbag that repeatedly inflates and deflates to massage the foot portion F can also be adopted.
