The ground is placed at a position corresponding to the length of the foot of the wearer, and the three leg holding members are fixedly placed at predetermined positions corresponding to the length of the foot of the wearer. Therefore, the position of the foot holding member (lower limb holding portion) of the treatment portion corresponding to the root side of the foot and the position of the foot holding member of the foot holding member adjacent to the treatment portion of the root portion of the corresponding leg are arranged to be deviated. The problem of the situation of the massage position that the therapist is expecting.

Accordingly, an object of the present invention is to provide a massage chair that can prevent a lower limb holding portion from being disposed at a massage position that is deviated from a subject, and that is more precisely treated by a massage position desired by the wearer.

In order to solve the above problems, the present invention requires the following means (1) to (13).

(1) The massage chair according to the first aspect of the present invention includes a seat portion and a foot mounting portion, and the leg mounting portion includes a first lower limb holding portion rotatably provided in front of the seat portion, and abutting a second lower limb holding portion provided on the first lower limb holding portion, and a third lower limb holding portion provided on the opposite side of the first lower limb holding portion adjacent to the second lower limb holding portion, and each of the second lower limb holding portions The first lower limb holding portion, the second lower limb holding portion, and the third lower limb holding portion massage the lower limbs of the wearer, and the second lower limb holding portion and the third lower limb holding portion of the foot placing portion are each The first lower limb holding portion is slidably movable toward the longitudinal direction of the wearer's foot independently of each other.

In this manner, the second lower limb holding portion and the third lower limb holding portion are slidably movable toward the longitudinal direction of the foot of the wearer independently of each other, so that the second lower limb holding portion and the second lower limb holding portion can be The third lower limb holding portions are independently disposed at an arbitrary sliding movement position, that is, a position desired by the treating person. As a result, more precise treatment can be performed at the massage position desired by the wearer.

(2) The massage chair further includes a drive source, and the second lower limb holding portion is slidably moved in the longitudinal direction of the foot of the wearer independently of the first lower limb holding portion and the third lower limb holding portion.

In this configuration, for example, the third lower limb holding portion is placed at a predetermined sliding position in accordance with the length of the foot of the wearer, and the holding interval between the first lower limb holding portion and the third lower limb holding portion is maintained. By driving the driving source, the second lower limb holding portion can be slid and moved toward the longitudinal direction of the wearer's foot. Thereby, the therapeutic massage can be performed by each of the first lower limb holding portion and the third lower limb holding portion, and the therapeutic massage can be performed by the second lower limb holding portion at any position within the range therebetween.

The second lower limb holding portion is slidably moved in a state.

(4) The massage chair according to any one of the preceding claims, wherein the first lower limb holding portion is supported by the seat portion so as to be rotatable at an arbitrary angle, but does not have a moving distance in a longitudinal direction of a foot of the wearer The adjustment function is better.

According to this configuration, when the first lower limb holding portion rotates, the first lower limb holding portion does not substantially move in the longitudinal direction of the foot. Therefore, the acupuncture points and muscles of the foot near the knee of the wearer can be accurately stimulated at the lower limb angles of the wearer who adjusts the rotation angle of the first lower limb holding portion. In other words, the first lower limb holding portion is substantially rotatably supported by the seat portion without being slidably moved in the longitudinal direction of the foot of the wearer. The above-mentioned "adjustment of the movement distance in the longitudinal direction of the foot of the therapist" or "sliding movement substantially in the longitudinal direction of the foot" means that the treatment position from the vicinity of the knee of the wearer to the toe is deviated. In the above configuration, the rotation angle of the first lower limb holding portion can be adjusted, and the treatment position of the portion from the knee of the wearer toward the toe is not changed in the longitudinal direction of the foot with the turning operation. However, depending on the rotation mechanism, there is a case where there is a slight movement in the longitudinal direction of the foot due to the play and the play on the mechanism, or the elastic movement of the elastic material. The above-mentioned "substantially does not accompany the sliding movement in the longitudinal direction of the foot of the treating person" means a slight movement in the longitudinal direction of the foot which does not accompany the degree of deviation of the treatment position.

In the third use state shown in FIG. 12, first, the lower limbs are accommodated in the first recessed portion 1D, the second recessed portion 2D, and the third recessed portion 3D in a state where only the first lower limb holding portion 1 is disposed at the uppermost storage position. The second lower limb holding portion 2 and the second lower limb holding portion 2 are slid by the sliding movement of the second supporting member 62 slidably supported by the first supporting member 61 by aligning the rear side of the knee to the upper end of the first lower limb holding portion 1 The three lower limb holding portions 3 are slid in the longitudinal direction of the foot (toe direction) in a state in which the distance between them is the shortest storage state, and are adjusted to an arbitrary rotation angle (for example, about 45 degrees) and conform to the rotation. The lower limb of the user is placed in a state in which the length of the lower limb is at an angle (Fig. 12a). At this time, the longitudinal direction distance of the lower end of the first lower limb holding portion 1 and the upper end of the third lower limb holding portion 3 is the first lower limb length L1 of the lower limb of the wearer suitable for the state, and the first lower limb holding portion The longitudinal direction distance between the upper end of the lower limb and the upper end of the second lower limb holding portion 2 is set such that the lower limb of the patient in this state is accommodated in the second upper half lower limb length L21'. In the setting operation (Fig. 12a), the first lower limb holding portion 1 is in a stationary state, and the second lower limb holding portion 2 and the third lower limb holding portion 3 are all in the direction of the toe in the longitudinal direction (the first lower limb holding portion 1) The opposite side direction) slides the movement state S2 of the same movement amount.

Next, in this set state, only the second lower limb holding portion 2 is slidably moved along the longitudinal direction of the foot by the second driving source 71, and at the same time, the therapeutic device provided in each lower limb holding portion 4 Perform treatment at each position of the lower limbs (Fig. 12b). At this time, the longitudinal direction distance of the lower end of the first lower limb holding portion 1 and the upper end of the third lower limb holding portion 3 is the first lower limb length L1 set to the length of the foot of the wearer suitable for the state, and the second lower limb holding portion 2 is only sliding movement within the range of the first lower limb length L1. Here, the second side treatment member 42S provided on each surface in the second concave portion 2D of the second lower limb holding portion 2 is the left and right second side expansion and contraction pockets 420S, and is supplied by a fluid (not shown). The mechanism is filled with air in the bag to be in an expanded state, and is slidably moved in this expanded state. By sliding the movement, the side of the calf and the ankle of the therapist can be rubbed by the stimulation, and the so-called rubbing treatment can be performed, or the side of the calf of the therapist can be strongly pressed and pushed or pulled. The so-called telescopic treatment. In this treatment operation (Fig. 12b), the first lower limb holding portion 1 and the third lower limb holding portion 3 are in a stationary state S1, and only the second lower limb holding portion 2 is in a sliding state S2. At this time, the abutting force of the third lower limb holding portion 3 toward the sole corresponding to the treatment position of the second lower limb holding portion 2 is adjusted by the elastic reaction force of the elastic supporting member 65 supported by the third supporting member 63. Further, in the other treatment operation, when only the second lower limb holding portion 2 is slidably moved, the position of the third lower limb holding portion 3 is slightly changed by the elastic reaction force of the elastic supporting member 65 that supports the third supporting member 63. The ground may be slidably moved in the longitudinal direction of the leg disposed on the foot placement portion O.

As described above, in the first embodiment, the second lower limb holding portion 2 is movable to the position expected by the wearer by driving the second drive source 71. Further, the third lower limb holding portion 3 can be moved to the position desired by the wearer by expanding and contracting the elastic supporting member 65. For example, when the length of the foot of the wearer is too large to sufficiently hold the lower portion of the lower leg in the first lower limb holding portion 1, the second lower limb holding portion 2 is slid toward the first lower limb holding portion 1 side. The lower portion of the lower leg can also be fully massaged by the treatment member 4 of the second lower limb holding portion 2. Further, in addition to the lower massage of the lower leg, in the case where the ankle is sufficiently massaged, by sliding the second lower limb holding portion 2 toward the third lower limb holding portion 3, the vicinity of the ankle can be held by the second lower limb The treatment member 4 of the portion 2 is fully massaged.

(The effect of the first embodiment)

Hereinafter, the operational effects in the configuration of the first embodiment described above will be described.

In the massage chair of the first embodiment, the second lower limb holding portion 2 has a configuration in which the first lower limb holding portion 1 is slidably moved in the longitudinal direction of the foot of the wearer, and the third lower limb holding portion 3 also has a The first lower limb holding portion 1 is configured to be slidably movable in the longitudinal direction of the foot of the wearer. Further, the second lower limb holding portion 2 and the third lower limb holding portion 3 are each independently expandable and contractible. In this way, the second lower limb holding portion 2 and the third lower limb holding portion 3 can be individually slidably moved by not necessarily interlocking, and the three leg holding members can be independently disposed at an arbitrary sliding movement position, that is, , the location of the person who is being treated. As a result, the treatment member 4 disposed in the second lower limb holding portion 2 and the third lower limb holding portion 3 can sufficiently massage the position of the patient.

Further, in the first embodiment, as described above, the second lower limb holding portion 2 is slidably moved in the longitudinal direction of the foot of the wearer by providing the first lower limb holding portion 1 and the third lower limb holding portion 3 independently. With the second drive source 71, the third lower limb holding portion 3 can be placed at a predetermined sliding position, and the sliding positions of the first lower limb holding portion 1 and the third lower limb holding portion 3 can be opened to the lower limbs suitable for the wearer. When the distance is fixed and fixed, by driving the second drive source 71, only the second lower limb holding portion 2 can be slid and moved toward the longitudinal direction of the wearer's foot (refer to FIG. 10). Thereby, in addition to the therapeutic massage by the first lower limb holding portion 1 and the third lower limb holding portion 3, the therapeutic massage can be performed by the second lower limb holding portion 2 at any position within the range therebetween.

Further, in the first embodiment, as described above, the massage chair includes: a first support member 61 that supports and rotatably provides the first lower limb holding portion 1 in front of the seat portion B, and the second support member a second support member 62 supported by the lower limb holding portion 2 and slidably movable toward the longitudinal direction of the foot of the wearer for the first support member 61, the second drive source 71 being the first support member 62 for the first The support member 61 slides in the longitudinal direction of the foot of the wearer. Thereby, as shown in FIG. 6, the first lower limb holding portion is used by using the support member constituted by the first support member 61 and the second support member 62 slidably mounted to the first support member 61. 1 and the second lower limb holding portion 2 are mounted, and the second supporting member 62 can be accurately rotated together with the first supporting member 61 by a relatively simple supporting mechanism, only the second supporting member 62 is attached to the first supporting member 61. Slide the movement precisely. And with a simple support mechanism, a strong support mechanism can be constructed.

Further, in the first embodiment, as described above, the first lower limb holding portion 1 is supported by the seat portion B so as to be rotatable at an arbitrary angle, but does not have a movement in the longitudinal direction of the foot of the wearer. Distance adjustment function. The first lower limb holding portion 1 of the first embodiment is supported by the first support member 61 having a support structure having an adjustment of the rotation angle of the seat portion B, and the adjustment of the rotation angle generated by the support structure It does not accompany the substantial movement adjustment of the position of the length of the foot. Therefore, the acupuncture points and muscles of the foot near the knee of the wearer can be accurately stimulated at the respective lower limb angles of the wearer adjusted with the rotation angle of the first lower limb holding portion 1. In other words, the first lower limb holding portion 1 is substantially rotatably supported by the seat portion B without being slidably moved in the longitudinal direction of the foot of the wearer. The above-mentioned "substantial movement adjustment of the position in the longitudinal direction of the foot" or "sliding movement in the longitudinal direction of the foot substantially" means that the treatment position from the vicinity of the knee of the wearer toward the toe is deviated. The configuration is such that the rotation angle of the first lower limb holding portion 1 can be adjusted, and the treatment position of the portion from the knee of the wearer toward the toe is not changed in the longitudinal direction of the foot with the turning operation. However, depending on the rotation mechanism, there is a case where there is a slight movement in the longitudinal direction of the foot due to the play and the play on the mechanism, or the elastic movement of the elastic material. In other words, the above-described "sliding movement in the longitudinal direction of the foot of the person who does not substantially accompany the treatment" means that a slight movement in the longitudinal direction of the foot is allowed without accompanying the deviation of the treatment position.

Further, in the first embodiment, as described above, the massage chair further includes an elastic support member 65, at least one of the seat portion B, the first lower limb holding portion 1 or the second lower limb holding portion 2, and the third portion The third lower limb holding portion 3 is elastically supported between the lower limb holding portions 3. The third lower limb holding portion 3 is a leg housing portion 3D that is in contact with the sole of the wearer and accommodates the foot, and the lower limb of the wearer is placed in the foot receiving portion 3D to accommodate the foot of the wearer on the foot. In the portion O, the third lower limb holding portion 3 is slidably moved, and the elastic supporting member 65 is extended in accordance with the sliding movement of the third lower limb holding portion 3, and is positioned in the longitudinal direction of the leg corresponding to the length of the lower limb of the wearer. The third lower limb holding portion 3 is elastically supported in a state in which an upward elastic reaction force occurs. According to this configuration, the third lower limb holding portion 3 is elastically supported by the elastic supporting member 65, and the foot of the wearer is placed in the third lower limb holding portion 3 so that the elastic supporting position can be changed by the elastic reaction force. The surface pressure from the third lower limb holding portion 3 due to the elastic reaction force is applied to the sole of the wearer accommodated in the leg housing portion 3D. Thereby, the lower limb (sole) of the wearer is accurately accommodated and held in a state in which the sole and the third lower limb holding portion 3 are not separated from each other and are abutted with a moderate elastic reaction force. The treatment is adjusted to a more precise position.

Further, the elastic supporting member 65 further urges the third lower limb holding portion 3 toward the first lower limb holding portion 1 side, and approaches the third lower limb holding portion 3 toward the first lower limb holding portion 1 when not in use. Mobile is also available. In this way, by automatically pushing the direction in which the entire length of the foot placing portion O is shortened, it is possible to maintain a light storage form when not in use.

Further, in the first embodiment, as described above, the massage chair is characterized in that it includes a seat portion B, a foot mounting portion O, and a second drive source 71, and the foot mounting portion O includes a rotatably provided a first lower limb holding portion 1 in front of the seat portion B, a second lower limb holding portion 2 provided adjacent to the first lower limb holding portion 1, and the first lower limb holding adjacent to the second lower limb holding portion 2 The third lower limb holding portion 3 provided on the opposite side of the portion 1 and the first lower limb holding portion 1, the second lower limb holding portion 2, and the third lower limb holding portion 3, respectively, and the lower limbs of the therapist are massaged The treatment member 4 and the second drive source 71 are movable or rotating with the first lower limb holding portion 1 in a movable range between the first lower limb holding portion 1 and the third lower limb holding portion 3, The movement or the turning operation of the third lower limb holding portion 3 independently slides the second lower limb holding portion 2 toward the longitudinal direction of the wearer's foot. Here, in the above-described conventional massage machine having the conventional link mechanism, when the abutting surface of the toe-side leg holding member is pushed out, three of the link mechanisms are used. The foot holding members (lower limb holding portions) are arranged at predetermined positions. Therefore, in particular, the position of the foot holding member (the lower limb holding portion) corresponding to the treatment portion on the root side of the foot and the foot holding member of the foot holding member adjacent to the treatment portion on the root side of the corresponding leg are disposed. The problem of the situation that deviates from the massage position of the visitor. According to the above configuration, the second lower limb holding portion is provided independently of the first lower limb holding portion 1 and the third lower limb holding portion 3 between the first lower limb holding portion 1 and the third lower limb holding portion 3. (2) The second drive source 71 for sliding movement in the longitudinal direction of the foot of the wearer, and the three lower limb holding portions of the massage machine of the above-described conventional technique are moved toward the predetermined position by the link mechanism By driving the second drive source 71, the second lower limb holding portion 2 can be moved to the portion expected by the wearer independently of the first lower limb holding portion 1 and the third lower limb holding portion 3. Thereby, it is possible to suppress the position of the lower limb holding portion from being displaced from the massage position expected by the wearer.

In other words, by the second drive source 71, only the second lower limb holding portion 2 is slidably moved in a state independent of the rotation of the first lower limb holding portion 1 and the movement or rotation of the third lower limb holding portion 3. For example, in a state where the length of the foot is fitted to a length suitable for the wearer, the treatment position by the second lower limb holding portion 2 can be easily adjusted by the independent second drive source 71.

Further, in the first embodiment, as described above, the treatment unit 4 includes: each of the two side portions of the pair of first concave portions 1D and each of the side portions of the wearer from the knee to the lower leg.

Further, the second lower limb holding portion 2 and the third lower limb holding portion 3 are slidably movable toward the longitudinal direction of the foot of the wearer with respect to the first lower limb holding portion 1 independently of each other. The second lower limb holding portion 2 and the third lower limb holding portion 3 can be slidably moved in the longitudinal direction of the foot of the first lower limb holding portion 1 independently of each other, so that the second lower limb holding portion 2 can be moved. The third lower limb holding portion 3 is independently disposed at an arbitrary sliding movement position, that is, a position expected by the wearer. As a result, more precise treatment can be performed at the massage position desired by the wearer. Further, in the massage chair of the first embodiment, the lower limbs are accurately held by the first to third lower limb holding portions 1 to 3 from the three-divided position, and can be shared by the first to third lower limb holding portions 1 to 3 The resulting support and treatment independently treats the side and back of the calf of the subject.

Further, among the conventional massage machines of the above-mentioned conventional techniques, the foot placement portion having the configuration in which the left and right legs of the wearer are disposed together is because the left and right calves of the wearer cannot be held at both sides. The massage cannot be sufficiently performed, and the left and right legs of the therapist cannot be inserted, and there is a problem that the patient cannot be stably maintained. Therefore, when the air bag in the recessed portion such as the foot is inflated, the user's foot accommodated in the concave portion is pushed out toward the opening side of the concave portion, and the side surface and the back surface of the wearer's foot cannot be sufficiently massaged. The problem that will occur in the situation. In the above-mentioned conventional massage machine, the air bag is placed in the air bag in which the left and right legs of the wearer are held together, and the air bag on the back side of the foot is not provided, and the feet of the person who cannot be treated are not provided. The subject of full massage. In this case, the first to third lower limb holding portions 1 to 3 in the above configuration are provided by the first side treatment member 41S and the first bottom treatment member from the uppermost portion in which the lower limb is accurately held by the three division positions. 41B, the side of the calf of each foot and the two sides can be treated simultaneously or sequentially or interactively, so that the feet of the therapist can be fully massaged.

Further, in the first embodiment, as described above, the second lower limb holding portion 2 includes a pair of second concave portions 2D which are respectively disposed between the ankles and the lower leg of the two legs of the therapist, and the treatment member 4 The pair of second side treatment members 42S are provided on the respective side portions of the pair of second concave portions 2D, and are applied to the side portions of the wearer from the ankle to the lower leg. According to the above configuration, the portion from the lower leg to the ankle of each leg can be accommodated in the pair of second recessed portions 2D directly under the support portion near the lower portion of the knee formed by the first recessed portion 1D. Thereby, the lower limbs can be accurately held while maintaining the angle of the lower limb of the wearer's foot at a predetermined angle. In addition to the treatment by the first lower limb holding portion 1, when the second lower limb holding portion 2 performs treatment, the lower limbs are divided into three parts by the first side treatment member 41S and the first bottom treatment member 41B. In addition to the uppermost treatment, the two sides of the range from the lower leg to the ankle can be treated simultaneously or sequentially or interactively, so that the various treatments can be more fully massaged from a wide range of dispersed positions. Lower limbs.

In the first embodiment, as described above, the pair of first side treatment members 41S are first side expansion and contraction pockets 410S that are respectively expandable and contractible by air flowing in or discharged, the first bottom portion. The treatment member 41B is a first bottom expansion and contraction bag 410B that is expandable and contractible by air flowing in or being discharged. The first side expansion and contraction bag 410S and the first bottom expansion and contraction bag 410B are expandable and contractible independently of each other. . By placing the expansion and contraction bags that are independent of each other and being independently expanded and contracted at the side and the bottom, respectively, the side expansion treatment and the expansion treatment of either or both of the bottom portions can be individually performed by individual time points. It is carried out in situ or in combination at any time, so that a more full massage effect can be obtained.

In the first embodiment, as described above, the first bottom treatment member 41B includes a plurality of first bottom expansion and contraction pockets 410B that are arranged in the vertical direction at positions corresponding to the respective bottom surfaces of the first concave portion 1D. These first bottom expansion pockets 410B are sized to expand and contract independently of each other. According to this configuration, the upper and lower expansion treatments corresponding to the bottom surface can be combined at individual or arbitrary time points by individual time points, so that a more sufficient massage effect can be obtained.
