Here, the left and right second side inflatable bags 420S, which are the second side treatment elements 42S provided so as to correspond to the respective surfaces in the second recess 2D of the second lower limb holding part 2, are supplied with an air supply (not shown). The mechanism is in an inflated state in which the bag is filled with air, and slides in the inflated state. By this sliding movement, the side of the user's calf and ankle is rubbed while being pressed, so-called rubbing treatment is performed, or the side of the user's calf is pushed and pulled while being strongly pressed and fixed. Stretching treatment can be performed.

(Second usage state)
In the second use state shown in FIG. 11, first, the lower limbs are accommodated in the first concave portion 1D, the second concave portion 2D, and the third concave portion 3D while only the first lower limb holding portion 1 is disposed at the uppermost storage position. By aligning the calf with the upper end of the first lower limb holding part 1, the second lower limb holding part 2 and the third lower limb are moved by the sliding movement of the second support member 62 slidably supported with respect to the first support member 61. The holding portion 3 is slid to the middle position in the longitudinal direction of the leg (foot direction) while keeping the mutual distance in the shortest state, and the lower half of the lower limb of the user is arbitrarily rotated. An angle (for example, about 45 degrees) and a length shorter than the length of the leg at the rotation angle are set in a state where the adjustment is finished (FIG. 11a). At this time, the longitudinal distance between the lower end of the first lower limb holding unit 1 and the upper lower half of the second lower limb holding unit 2 is such that the knee of the user in that state floats above the first lower limb holding unit 1. It is set to the upper half leg length L21. In this setting operation (FIG. 11a), the first lower limb holding unit 1 remains stationary and the second lower limb holding unit 2 and the third lower limb holding unit 3 are both moved to the moving state S2 by the same moving amount.

  Next, in the set state, only the third lower limb holding part 3 is slid along the longitudinal direction of the leg by the elastic support member 65, and together with this, the treatment element 4 provided in each lower limb holding part. Treatment is performed on each position of the lower limb (FIG. 11b). At this time, the longitudinal distance of the leg between the lower end of the first lower limb holding unit 1 and the upper end of the second lower limb holding unit 2 is set to the second upper half lower leg length L21 appropriate for the lower limb of the user in that state. Yes, the third lower limb holding part 3 slides and moves in the longitudinal direction of the leg arranged on the footrest part O only in the second lower half lower limb region L22 ahead of the second upper half lower limb length L21. Here, the left and right first side inflatable bags 410S, which are the first side treatment elements 41S provided on each surface in the first recess 1D of the first lower limb holding part 1, and the first bottom part treatment elements 41B. The left and right second side inflatable bags 420S which are the second side portion treatment elements 42S provided on each surface in the second recess 2D of the second lower limb holding portion 2 and the bottom bottom inflatable bag 410B, Each of the third side inflatable and inflatable bags is a third side treatment element 43S provided on both sides of the third lower limb holding portion 3 and inflated with a bag filled with air by a fluid supply mechanism (not shown). While the 430S is in an expanded state, only the third lower limb holder 3 slides along the longitudinal direction of the leg. By this sliding movement, the toes are pushed or moved while pressing and stimulating the side of the calf's calf, so that the so-called expansion / contraction treatment in the extending direction of the whole leg and the rubbing treatment by rubbing the calf are performed. be able to.

(Third use condition)
In the third use state shown in FIG. 12, first, the lower limbs are accommodated in the first concave portion 1D, the second concave portion 2D, and the third concave portion 3D while only the first lower limb holding portion 1 is disposed at the uppermost storage position. By aligning the back of the knee with the upper end of the first lower limb holding unit 1, the second support member 62 slidably supported with respect to the first support member 61, thereby moving the second lower limb holding unit 2 and the third lower limb holding unit 2. The lower limb holding unit 3 is slid and moved in the longitudinal direction of the leg (toe direction) while being stored in a state where the distance between each other is minimized, and the lower limb of the user is rotated at an arbitrary rotation angle (for example, about 45 degrees). And it sets in the state which finished adjustment as length which suited the length of the leg in the rotation angle (Drawing 12a). At this time, the longitudinal distance between the lower end of the first lower limb holding unit 1 and the upper end of the third lower limb holding unit 3 is set to the first lower limb length L1 appropriate for the lower limb of the user in that state, and the first lower limb holding The longitudinal distance between the lower half of the part 1 and the upper half of the lower limb holding part 2 is set to the second upper half leg length L21 ′ in which the lower limb of the user in that state is accommodated. In this setting operation (FIG. 12 a), the first lower limb holding unit 1 remains stationary, and the second lower limb holding unit 2 and the third lower limb holding unit 3 are both moved in the longitudinal foot direction (first lower limb holding unit) by the same movement amount. The movement state S2 is slid in the direction opposite to 1).

  Next, in this set state, the second drive source 71 causes only the second lower limb holder 2 to slide along the longitudinal direction of the leg, and with this, the treatment element 4 provided in each lower limb holder. To treat each position of the lower limb (FIG. 12b). At this time, the longitudinal distance between the legs of the lower end of the first lower limb holding part 1 and the upper end of the third lower limb holding part 3 remains set to the first lower limb length L1 appropriate for the length of the leg of the user in that state, The second lower limb holder 2 slides only within the range of the first lower limb length L1. Here, the left and right second side inflatable bags 420S, which are the second side treatment elements 42S provided on each surface in the second recess 2D of the second lower limb holding part 2, are placed in the bag by a fluid supply mechanism (not shown). The air is filled with air, and it slides and moves in this expanded state. By this sliding movement, the side of the user's calf and ankle is rubbed while being pressed, so-called rubbing treatment is performed, or the side of the user's calf is pushed and pulled while being strongly pressed and fixed. Stretching treatment can be performed. In this treatment operation (FIG. 12b), the first lower limb holding unit 1 and the third lower limb holding unit 3 remain in the stationary state S1, and only the second lower limb holding unit 2 is in a moving state S2 that slides. At this time, the contact force of the third lower limb holder 3 to the sole according to the treatment position of the second lower limb holder 2 is adjusted by the elastic reaction force of the elastic support member 65 that supports the third support member 63. . As another treatment operation, when only the second lower limb holding portion 2 slides, the position of the third lower limb holding portion 3 is slightly changed by the elastic reaction force of the elastic support member 65 that supports the third support member 63. You may slide and move toward the longitudinal direction of the leg arrange | positioned at the footrest part O. FIG.

  As described above, in the first embodiment, the second lower limb holding unit 2 is configured to be able to move to a position desired by the user by driving the second drive source 71. Further, the third lower limb holding unit 3 is configured to be able to move to a position desired by the user by expanding and contracting the elastic support member 65. For example, when the length of the user's leg is large and the lower part of the calf cannot be sufficiently held by the first lower limb holding part 1, the second lower limb holding part 2 is slid to the first lower limb holding part 1 side. By moving, the lower part of the calf can be sufficiently massaged by the treatment element 4 of the second lower limb holding part 2. Also, if you want to massage the area around the ankle more than massaging the lower part of the calf, slide the second lower limb holding part 2 to the third lower limb holding part 3 side to hold the second leg part near the ankle. It is possible to massage sufficiently with the treatment element 4 of the part 2.

(Operational effects of the first embodiment)
Hereinafter, the operation and effect in the configuration of the first embodiment will be described.
In the chair type massage machine of the first embodiment, the second lower limb holding part 2 has a configuration capable of sliding in the longitudinal direction of the leg of the user with respect to the first lower limb holding part 1, and the third lower limb. The holding part 3 also has a structure that can slide in the longitudinal direction of the legs of the user with respect to the first lower limb holding part 1. The second lower limb holding unit 2 and the third lower limb holding unit 3 are each slidable independently of each other. In this way, each of the second lower limb holding unit 2 and the third lower limb holding unit 3 can be slid separately without being interlocked, so that each of the three leg holding members can be moved to an arbitrary slide movement position, that is, It can be arranged independently at a position desired by the user. As a result, the position desired by the user can be massaged sufficiently by the treatment element 4 disposed in the second lower limb holding part 2 and the third lower limb holding part 3.

  In the first embodiment, as described above, the second lower limb holder 2 is moved in the longitudinal direction of the leg of the user independently of the first lower limb holder 1 and the third lower limb holder 3. By providing the second drive source 71 for sliding movement, the third lower limb holding unit 3 is arranged at a predetermined slide position, and the slide positions of the first lower limb holding unit 1 and the third lower limb holding unit 3 are determined by the user. By driving the second drive source 71 in a set state in which the distance suitable for the lower limb length is kept fixed, only the second lower limb holding portion 2 can be slid in the longitudinal direction of the user's leg. (See FIG. 10). Thereby, while performing the treatment massage by each of the first lower limb holding unit 1 and the third lower limb holding unit 3, it is possible to perform the treatment massage by the second lower limb holding unit 2 at any position within the range therebetween. It has become.

  In the first embodiment, as described above, the chair-type massage machine supports the first lower limb holding unit 1 and is provided with a first support member 61 that is rotatably provided in front of the seat B. A second support member 62 that supports the second lower limb holding unit 2 and is slidable in the longitudinal direction of the legs of the user with respect to the first support member 61, and the second drive source 71 includes: The second support member 62 is configured to slide relative to the first support member 61 in the longitudinal direction of the legs of the user. Accordingly, as shown in FIG. 6, the first lower limb is formed by using the support member constituted by the first support member 61 and the second support member 62 slidably attached to the first support member 61. By attaching the holding part 1 and the second lower limb holding part 2, the first support member 61 and the second support member 62 are reliably rotated by the relatively simple support mechanism, and only the second support member 62 is the first. The support member 61 can be reliably slid. In addition, a simple support mechanism can be used to form a strong support mechanism.

  In the first embodiment, as described above, the first lower limb holding part 1 is supported so as to be rotatable and adjustable at an arbitrary angle with respect to the seat part B, and the longitudinal direction of the leg of the user It has no function to adjust the distance traveled to. The first lower limb holding unit 1 of the first embodiment is supported by a first support member 61 having a support structure that can only adjust the rotation angle with respect to the seat B, and the rotation angle of the support structure can be adjusted. During adjustment, there is no substantial movement adjustment of the longitudinal position of the leg. For this reason, in each lower limb angle of the user associated with the rotation angle adjustment of the first lower limb holding unit 1, it is possible to accurately stimulate the acupoints and muscles in the vicinity of the user's knee. That is, in this configuration, the first lower limb holding unit 1 is supported so as to rotate with respect to the seat B without substantial sliding movement in the longitudinal direction of the leg of the user. Means that. The above-mentioned “substantial movement adjustment of the longitudinal position of the leg” or “substantial sliding movement of the leg in the longitudinal direction” means that the treatment position of the portion from the vicinity of the knee of the user toward the foot tip is shifted. In the above-described configuration, the rotation angle of the first lower limb holding unit 1 can be adjusted, and the treatment position of the portion from the knee of the user toward the tip of the foot with the rotation operation is the leg position. Identify a configuration that does not change in the longitudinal direction. However, depending on the rotation mechanism, there may be some movement in the longitudinal direction of the leg due to rattling, play on the mechanism, or elastic movement via an elastic material. In other words, the phrase “without substantial sliding movement in the longitudinal direction of the leg of the user” allows a slight movement in the longitudinal direction of the leg without causing a shift in the treatment position. Meaning.

  In the first embodiment, as described above, the chair type massage machine includes at least one of the seat B, the first lower limb holding unit 1 or the second lower limb holding unit 2, and the third lower limb holding unit 3. Is further provided with an elastic support member 65 that elastically supports the third lower limb holding portion 3. The third lower limb holding part 3 has a foot accommodating part 3D that accommodates the foot by contacting the sole of the user, and accommodates the foot of the user in the foot accommodating part 3D. By setting the lower limb of the user, the third lower limb holding unit 3 slides, and the elastic support member 65 extends as the third lower limb holding unit 3 slides, At the longitudinal position of the leg corresponding to the length, the third lower limb holding part 3 is configured to be elastically supported in a state where an upward elastic reaction force is generated. According to this configuration, the third lower limb holder 3 is elastically supported by the elastic support member 65, and the elastic support position is set by the elastic reaction force by setting the user's foot into the third lower limb holder 3. At this time, the surface pressure from the third lower limb holding part 3 due to the elastic reaction force is applied to the soles of the users who are accommodated in the foot accommodating part 3D. As a result, the user's lower limbs (sole) are securely contained and held while the set sole and the third lower limb holder 3 are kept in contact with an appropriate elastic reaction force without leaving. It is possible to adjust the treatment element to an accurate position.

  The elastic support member 65 further urges the third lower limb holding part 3 toward the first lower limb holding part 1, and the third lower limb holding part 3 is in contact with the first lower limb holding part 1 when not in use. It is good also as what moves close to the side. Thus, by automatically energizing the footrest portion O in the direction of reducing the overall length, the compact storage configuration can be maintained when not in use.

  In the first embodiment, as described above, the chair type massage machine includes the seat B, the first lower limb holding unit 1 rotatably provided in front of the seat B, and the first lower limb. A second lower limb holding part 2 provided adjacent to the holding part 1 and a third lower limb holding provided adjacent to the opposite side of the second lower limb holding part 2 from the first lower limb holding part 1 A footrest portion O including a portion 3 and a treatment element 4 provided in each of the first lower limb holding portion 1, the second lower limb holding portion 2 and the third lower limb holding portion 3 to massage the lower limbs of the user. Within the movable range between the first lower limb holding part 1 and the third lower limb holding part 3, the movement or rotation of the first lower limb holding part 1 and the third lower limb holding part 3 Independently of each movement or rotation, the second lower limb holder 2 is slid in the longitudinal direction of the user's leg. Characterized in that it comprises a second drive source 71 for causing the. Here, in the massage machine having the conventional link mechanism as enumerated in the background art, when the pressing surface of the leg holding member on the toe side is pushed out, the link mechanism causes the three leg holding members (lower limbs). (Holding unit) is arranged at a predetermined position. Therefore, in particular, the position of the leg holding member (lower limb holding part) corresponding to the treatment site on the base side of the leg and the leg holding member adjacent to the leg holding member corresponding to the treatment site on the base side of the leg There is a problem in that it may be disposed at a position shifted from the desired massage position. On the other hand, according to the said structure, between the 1st lower limb holding | maintenance part 1 and the 3rd lower limb holding | maintenance part 3, the 2nd lower limb holding | maintenance is independent of the 1st lower limb holding | maintenance part 1 and the 3rd lower limb holding | maintenance part 3. By providing the second drive source 71 for slidably moving the part 2 in the longitudinal direction of the user's leg, the three lower limb holders are determined in advance by the link mechanism as in the background art massage machine. Unlike the configuration of moving to a different position, by driving the second drive source 71, the second lower limb holding part 2 is made independent of the first lower limb holding part 1 and the third lower limb holding part 3 as desired by the user. It can be moved to the site. Thereby, it can suppress that the position of a leg holding | maintenance part arrange | positions in the position which shifted | deviated from the massage position which a user desires.

  That is, the second drive source 71 slides only the second lower limb holding unit 2 while being independent of the rotation of the first lower limb holding unit 1 and the movement or rotation of the third lower limb holding unit 3. Thus, for example, the treatment position by the second lower limb holding unit 2 can be easily adjusted by the independent second drive source 71 while keeping the length of the leg suitable for the user.

  Moreover, in 1st embodiment, as above-mentioned, the treatment element 4 is each provided in the both sides of each of a pair of 1st recessed part 1D, and treats each side part of the calf from a knee of a user. It includes a first side treatment element 41S and a first bottom treatment element 41B that is provided on both bottoms of each of the pair of first recesses 1D and treats the back of the calf from the knee of the user. In addition, the second lower limb holding unit 2 and the third lower limb holding unit 3 are configured to be slidable in the longitudinal direction of the legs of the user with respect to the first lower limb holding unit 1 independently of each other. In this way, by allowing each of the second lower limb holding part 2 and the third lower limb holding part 3 to be independently slidable in the longitudinal direction of the leg of the user with respect to the first lower limb holding part 1, The second lower limb holding unit 2 and the third lower limb holding unit 3 can be independently arranged at arbitrary slide movement positions, that is, positions desired by the user. As a result, more accurate treatment can be performed at the massage position desired by the user. Moreover, the chair type massage machine of 1st embodiment is supported by the 1st-3rd leg support parts 1-3, hold | maintaining a leg by the 1st thru | or 3rd leg support parts 1-3 reliably in a 3 division position. Independent of the treatment, the side and the back of the calf can be treated.

  In addition, among conventional massage machines as listed in the background art, those having a footrest portion configured to collectively arrange the left and right legs of the user hold both sides of the left and right calves of the user. Therefore, there is a problem that the massage cannot be sufficiently performed, and each of the left and right legs of the user cannot be sandwiched and cannot be held stably. For this reason, for example, when an airbag in a recess that accommodates a leg is inflated, the leg of the user accommodated in the recess is pushed out to the release side of the recess, and the both sides and back surface of the user's leg are massaged sufficiently There was a problem that the case where it was not possible to occur. Further, in the conventional massage machine, in which the airbag is arranged so as to sandwich the left and right legs of the user, since the airbag corresponding to the back side of the leg is not provided, each of the user The problem was that the legs could not be massaged sufficiently. On the other hand, the first side treatment element 41 </ b> S and the first bottom treatment element 41 </ b> B are formed at the uppermost portion where the lower limbs are securely held at the three-divided position by the first to third lower limb holding parts 1 to 3 in the above configuration. By this, it becomes possible to treat the back side and both sides of each leg at the same time, sequentially or alternately, so that each leg of the user can be massaged sufficiently.

  In the first embodiment, as described above, the second lower limb holding unit 2 includes a pair of second recesses 2D in which a portion between the ankle and the calf of each foot of the user can be disposed, and the treatment The child 4 includes a pair of second side treatment elements 42S provided on both sides of each of the pair of second recesses 2D and treating each side between the ankle of the user and the calf. ing. According to the above configuration, the portion between the calf and the ankle of each leg is accommodated in the pair of second recesses 2D immediately below the support portion near the lower part of the knee by the first recess 1D. . Thereby, both lower limbs can be reliably held while maintaining the angle of the lower limbs of the legs of the user to a predetermined one. Further, in addition to the treatment by the first lower limb holding unit 1, the second leg holding unit 2 also performs the treatment, thereby holding the lower limbs in three parts by the first side treatment element 41S and the first bottom treatment element 41B. In addition to the treatment at the top, it is possible to treat each leg in the range between the calf and ankle of each leg simultaneously, sequentially, or alternately, and in a position where the lower limbs of the user are widely dispersed. It has become something that can be massaged more fully.

  In the first embodiment, as described above, the pair of first side treatment elements 41S are first side inflatable bags 410S that can be inflated and inflated when air flows in or out. The first bottom treatment element 41B is a first bottom inflatable bag 410B that can be inflated and inflated when air flows in or out, and the first side inflatable bag 410S and the first bottom inflatable bag 410B. And can be expanded and contracted independently of each other. By providing inflatable and inflatable bags that can be inflated and inflated independently without correlating with each other, the expansion and contraction treatment of the side part and the expansion or contraction treatment of either or both of the side part are separately provided at their own timing. Or it can be performed in combination at an arbitrary timing, and it is possible to obtain a more sufficient massage effect.

  In the first embodiment, as described above, the first bottom treatment element 41B has a plurality of first bottom swellings arranged in parallel in the vertical direction at positions corresponding to the bottoms constituting the first recess 1D. These juxtaposed first bottom inflatable bags 410B including the shrinkable bags 410B can be inflated and shrunk independently of each other. If comprised in this way, the up-and-down expansion / contraction treatment corresponding to a bottom face can be performed separately at each unique timing, or in combination at any timing, and a more sufficient massage effect can be obtained. Yes.

(Second embodiment)
The chair type massage machine of the second embodiment shown in FIG. 13 is different from the chair type massage machine of the first embodiment in terms of the length in the depth direction of the second lower limb holder, and other basic configurations The structure, operation, and effects are the same as in the first embodiment. Hereinafter, the difference from the first embodiment will be mainly described.

  In the second embodiment, as shown in FIG. 13, the maximum length 2L in the depth direction (front-rear direction) of the second lower limb holder 2 is the maximum length in the depth direction (front-rear direction) of the first lower limb holder 1. It is assumed to be smaller than both 1L and the maximum length 3L in the depth direction (front-rear direction) of the third lower limb holder 3. In addition, the maximum length 1L in the depth direction (front-rear direction) of the first lower limb holding unit 1 is set to be smaller than the maximum length 3L in the depth direction (front-rear direction) of the third lower limb holding unit 3. The maximum length 2L in the depth direction of the second lower limb holding part 2 is configured to be short, and the second side treatment element 42S is disposed on each side surface of the second recessed part 2D formed in the inside thereof, so that the lower part of the ankle and calf The treatment can be performed intensively at a pinpoint without greatly deviating from a small treatment area such as the ankle nerve. In addition, the second side treatment element 42 is disposed only in a range behind the side of the ankle, and appropriate treatment corresponding to the shape of a thin ankle is possible as compared with other portions.

(Another embodiment example (modification))
