Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
1-6 has shown 1st Embodiment of the chair type massage machine 1 which concerns on this invention.
In each drawing, a part of the structure is omitted for convenience of explanation. Moreover, in the following description, the left-right direction of FIGS. 3-6 is called the front-back direction in an actual apparatus, and the up-down direction of FIGS. 3-6 is called the up-down direction in an actual apparatus. 3 through 6 is referred to as a horizontal direction or a width direction in an actual apparatus. These directions coincide with those seen from the user sitting on the chair type massage machine 1.

  First, the basic configuration of the chair type massage machine 1 will be described. This chair type massage machine 1 shows a seat part 2 (only the seat part frame 2a is shown except for FIG. 3) and a backrest part 3 provided at the rear part of the seat part 2 (other than FIG. 3 only shows the back part frame 3a). ). Further, a foot massage device 5 for massaging and massaging the lower limbs (especially calves) of the user seated on the seat 2 is provided at the front of the seat 2.

  The seat portion 2 is wide enough to support the user's buttocks from below. A base frame 6 for installing the chair type massage machine 1 on the floor surface F is provided at the lower part of the seat part 2, and the base part 6 supports the seat part 2 at a predetermined height. It has become. The basic frame 6 includes a lower frame 7 provided for grounding the floor, an upper frame 8 provided in accordance with the support height of the seat 2 above the lower frame 7, and the lower frame 7 and the upper frame. A box-shaped frame is formed by having a column portion 6 a that connects the upper and lower sides to the frame 8.

In the first embodiment, the base frame 6 also has a role of forming a storage position P for storing the foot massage device 5 between the lower frame 7 and the upper frame 8 (below the seat portion 2). (See FIG. 3).
The backrest 3 is formed with a width approximately the same as that of the seat 2, and the lower end of the backrest 3 is supported at the rear end of the seat 2 via a swinging portion 10 that is swingable about an axis in the left-right direction. Connected with the department. As a result, the backrest 3 is swingable (reclinable) behind the seat 2 so that the upper end of the backrest 3 can be tilted backward or raised forward. The drive structure for the reclining operation will be described later.

In the chair type massage machine 1, the upper part of the pair of left and right hinge pieces 11 provided to protrude upward on both the left and right sides of the seat frame 2a and the front part of the chair type massage machine 1 are bent forward by bending the lower part of the back frame 3a. The front end portions of the pair of left and right lever portions 12 provided so as to be connected to each other are connected by shaft portions each having a left-right axis. This connecting portion is a pair of left and right, and is a swinging portion 10. By this swinging portion 10, the rear end portion of the seat portion 2 and the lower end portion of the backrest portion 3 are connected so as to be swingable about the axis in the left-right direction.

  Inside the backrest part 3, a massage part 9 that performs massage operations such as squeezing, hitting, or vibrating against the back to waist of the user seated on the seat part 2 is provided so as to be movable up and down (FIG. 1). reference). A massage unit (not shown) that performs massage operations such as squeezing, striking, or vibrating the waist, buttocks, and thighs of the user seated on the seat 2 on the inside of the seat 2 and on the left and right sides of the seat 2. ) May be provided.

The foot massage device 5 has a substantially square shape when viewed from the front, and a box shape that exhibits a rounded triangular shape when viewed from the side. The front surface of the foot massage device 5 is a massage surface 5a, and a pair of left and right foot insertion portions 13 are formed to allow the user's lower limbs (left and right feet) to be fitted.
A leg massage device (not shown) for massaging the lower limbs is incorporated in the opposing surface inside each foot pocket 13. This lower limb massage device is configured to itch by swinging a plate that is long in the length direction of the foot left and right, or to be squeezed with an air bag that expands and contracts by air supply and discharge. Can do.

As shown in FIG. 2, a pair of left and right wheels 14 are rotatably provided at the corner portion between the bottom surface and the back surface of the foot massaging device 5 so as to be able to roll in the front-rear direction.
Thus, the chair type massage machine 1 provided with the seat part 2, the backrest part 3, and the foot massage device 5 can move the seat part 2 back and forth with respect to the basic frame 6, and the seat part 2 can be moved back and forth. The backrest part 3 can be reclined in conjunction with the movement of the footrest device 5 and the footgear device 5 can operate various posture changes. What moves the seat part 2 back and forth and interlocks the back and forth movement of the seat part 2 with the reclining operation of the backrest part 3 is a seat part moving mechanism 15, and the one that changes the posture of the foot massage device 5 is a posture changing mechanism. 16.

Next, the seat movement mechanism 15 will be described.
The seat portion moving mechanism 15 includes a guide portion 20 that guides the seat portion 2 so as to be movable in the front-rear direction, and an advancing / retreating drive portion 21 that moves (drives) the seat portion 2 in the front-rear direction along the guide portion 20. have.
The guide unit 20 is configured by the upper frame 8 of the base frame 6. That is, the upper frame 8 has a pair of left and right side members 24 whose longitudinal direction is directed in the front-rear direction along the left and right side portions of the seat frame 2a, and the front end portions of the left and right side members 24 are connected to each other. And a member 25. The left and right side members 24 are arranged at positions projecting outward in the left and right directions with respect to the width dimension of the seat frame 2a (external method in the left and right direction). The side member 24 and the front member 25 are formed of a square pipe having a hollow quadrangular cross section or the like.

On the other hand, the seat frame 2a is provided with a pair of left and right projecting members 27 extending obliquely downward in the left and right directions from the outer surfaces of the left and right sides. The left and right projecting members 27 are externally fitted with side members 24 provided on the base frame 6 and are slidable in the longitudinal direction (that is, the front-rear direction) of the side members 24. 28 is provided.
As described above, the left and right side members 24 of the upper frame 8 provided on the base frame 6 have a structure capable of slidably holding the left and right sliding portions 28 provided on the seat frame 2a in the front-rear direction. As a result, the guide portion 20 is configured. In addition, since the side member 24 is formed of a square pipe or the like, the sliding portion 28 receives a detent action and an anti-rattle action around the longitudinal direction (sliding axis) of the side member 24, and is stable. Can be slid.

The guide part 20 (the left and right side members 24) may be provided in parallel (horizontally) with the floor surface F, or may be provided so as to be inclined in the front rising direction so that the front end of the seat part 2 rises. In the case of inclining in the upward direction, it may be linearly inclined or inclined upward while drawing a curved concave curve.
The first embodiment employs a structure in which the side member 24 is inclined linearly and gently (with a small inclination angle) in the upward direction. Therefore, when the seat part 2 moves forward, the seat part moving mechanism 15 performs a “front raising operation” in which the front end of the seat part 2 rises as the seat part 2 moves forward. When moving backward, the more the seat 2 moves backward, the more “forward-down operation” is performed in which the front end of the seat 2 descends.

  An advancing / retreating drive unit 21 that moves (drives) the seat 2 in the front-rear direction with respect to the guide unit 20 is provided. For example, an electric feed screw mechanism can be employed for the advance / retreat drive unit 21. As is apparent from FIGS. 2 and 5, this electric feed screw mechanism has a feed screw shaft 31 that is rotationally driven by the electric motor 30 attached to the lower frame 7 of the base frame 6 in a forward projecting state. The nut member 32 that is screwed onto the seat screw frame 31 is held at the rear end portion of the seat frame 2a while being unable to rotate around the axis of the feed screw shaft 31.

  At the rear end of the seat frame 2a, there is provided a tail frame 35 formed in a crank shape by bending downward and further backward, and the rear ends of the left and right tail frames 35 are connected to each other. The nut member 32 is held by the rear member 36. The feed screw shaft 31 is inclined in the forward upward direction, and this inclines the side member 24 of the basic frame 6, that is, the guide portion 20 for guiding the longitudinal movement of the seat portion 2 in the forward upward direction. On the other hand, it is the structure for making the front-back direction of the nut member 32 parallel.

  As is clear from this, when the advancing / retreating drive unit 21 is operated (the feed screw shaft 31 is rotated by the electric motor 30 to move the nut member 32 back and forth, and the seat frame 2a is pushed and pulled back and forth), The seat portion 2 moves back and forth along the guide portion 20. Since the seat part 2 and the backrest part 3 are connected via the rocking part 10, when the seat part 2 moves forward, the lower end part of the backrest part 3 also moves forward, and conversely the seat part 2 moves backward. Sometimes the lower end of the backrest 3 is also moved backward.

However, since the reclining operation of the backrest 3 cannot be obtained in this state, the following structure is added to the seat movement mechanism 15.
That is, the backrest part 3 is provided with a rail member 40 in a direction connecting the lower end part and the upper end part thereof, and the base frame 6 is provided with a sliding holding part 41 for holding the rail member 40 of the backrest part 3. A rotation support portion 42 for holding the slide holding portion 41 itself is provided.

Specifically, the rail member 40 of the backrest part 3 is a pair of left and right vertical members 45 provided along the longitudinal direction (the user's back muscle direction leaning against the backrest part 3) among the back frame 3a of the backrest part 3. Is formed by. The vertical member 45 is formed of a square pipe having a hollow square cross section.
On the other hand, the slide holding portion 41 of the base frame 6 is fitted to the rail member 40 (left and right vertical members 45) of the backrest portion 3, and the rail member 40 is relatively movable in the longitudinal direction. It has a structure to hold it. In addition, since the vertical member 45 is formed of a square pipe or the like, the sliding holding portion 41 receives a detent action and an anti-rattle action around the longitudinal direction (moving axis) of the vertical member 45, and is stable. Relative movement can be performed.

On the other hand, the rotation support part 42 holds the sliding holding part 41 so as to be rotatable around the axis in the left-right direction, and the column part 6a on the rear side of the base frame 6 projects upward from the upper frame 8. In this position, it is provided so as to protrude inward in the left-right direction, and the sliding holding portion 41 is held at the tip in the protruding direction.
That is, when the seat portion 2 moves forward, if the forward pulling action is transmitted to the lower end portion of the backrest portion 3 via the swinging portion 10, the rail member 40 of the backrest portion 3 slides downward in the slide holding portion 41. At the same time, the sliding holding portion 41 tries to turn in the direction in which the upper end portion of the backrest portion 3 is tilted backward with the rotation center supported by the rotation support portion 42 as a fulcrum. Therefore, the downward sliding of the rail member 40 and the rearward rotation of the sliding holding portion 41 cooperate, and the backrest portion 3 moves the lower end portion of the backrest portion 3 together with the advancement of the seat portion 2. While moving forward, the reclining operation is performed so that the upper end of the backrest 3 is lowered and falls backward.

  On the other hand, when the seat portion 2 is moved backward, when the backward pushing action is transmitted to the lower end portion of the backrest portion 3 via the swinging portion 10, the rail member 40 of the backrest portion 3 slides upward in the sliding holding portion 41. At the same time as it tries to move, the sliding holding part 41 tries to rotate in the direction in which the upper end of the backrest part 3 is raised forward, with the rotation center supported by the rotation support part 42 as a fulcrum. Accordingly, the upward sliding of the rail member 40 and the forward rotation of the sliding holding portion 41 cooperate, and the backrest portion 3 moves the lower end portion of the backrest portion 3 together with the backward movement of the seat portion 2. The reclining operation is performed so that the upper end of the backrest 3 is raised while moving backward, and rises forward.

  By the way, at the time of the above-described reclining operation, the backrest portion 3 is such that the rail member 40 slides downward within the sliding holding portion 41. In other words, as the back reclining operation proceeds, the backrest portion 3 is pulled out forward, and as a result, the upper end portion of the backrest portion 3 becomes “one (one) vertical line”. It will descend along the way. Therefore, when it observes as the whole chair type massage machine 1, the upper end part of the backrest part 3 does not protrude largely backward from the state before reclining.

Here, the meaning of “along a single vertical line” is not a strict thing such as “a specific point always moves on one straight line (never moves away)”, but “backrest part 3 It is understood that the specific part that can be recognized as the upper end of the head moves up and down substantially straight without making a large detour.
For this reason, for example, even if the chair type massage machine 1 is installed close to the indoor wall surface W, the upper end portion of the backrest portion 3 is difficult to contact the indoor wall surface W during rearward reclining. The massage machine 1 can be installed close to the indoor wall surface W, which leads to the advantage that the indoor space is not narrowed.

Needless to say, even when the backrest part 3 is reclined forward after reclining (getting up forward), the upper end part of the backrest part 3 does not greatly protrude backward from the state before reclining. The effect that the chair type massage machine 1 can be installed close to the indoor wall surface W is enjoyed.
Next, the posture conversion mechanism 16 that performs posture conversion of the foot massage device 5 will be described.

As is apparent from FIGS. 1, 2 and 5, the posture changing mechanism 16 includes a swing arm 47 for connecting the seat 2 and the foot kneading device 5, and a swing drive of the swing arm 47. And a posture driving unit 48 for performing the above operation.
As shown in FIG. 1, the seat 2 is connected to the base end portion of the swing arm 47 at a substantially central portion of the seat frame 2a (between the left and right swing portions 10). A base fulcrum 50 is provided to support the swinging around the axis centered in the left-right direction. In addition, as shown in FIG. 2, in order to connect to the tip portion of the swing arm 47, the foot gripping device 5 has its shaft centered in the left-right direction at the upper back of the foot gripping device 5. A tip fulcrum 51 is provided to support swinging around the center.

As shown in FIG. 3, the swing arm 47 has a base end so that the foot gripping device 5 does not contact and interfere with the foot gripping device 5 when the foot gripping device 5 is stored in the storage position P below the seat 2. It is formed as having bent portions bent at an angle close to a substantially right angle at two positions, the side (side connected to the base fulcrum 50) and the end side (side connected to the tip fulcrum 51). Yes.
The posture driving unit 48 may employ, for example, an electric feed screw type expansion / contraction mechanism. This electric telescopic mechanism is such that a feed screw shaft 56 protrudes from one end portion of a cylinder portion 55 in a state where rotation around the shaft is disabled, and a nut that is screwed into the feed screw shaft 56 in the cylinder portion 55. A member (not shown) is accommodated. That is, by rotating the nut member around the feed screw shaft 56 with the electric motor 57 provided in the cylinder portion 55, the feed screw shaft 56 can be extended or contracted with respect to the cylinder portion 55. Yes.

This electric telescopic mechanism is provided with a radial lever that protrudes in the radial direction from the base fulcrum 50 of the seat frame 2 a, connects the front end of the cylinder portion 55 to the radial lever, and projects backward from the cylinder portion 55. The rear end portion of the feed screw shaft 56 held in the state is connected to the rear member 36 of the seat frame 2a (tail frame 35).
As is clear from this, when the posture driving unit 48 is operated (the nut member is rotated by the electric motor 57 to cause the feed screw shaft 56 to expand and contract, and the swing arm 47 swings back and forth), The squeezing device 5 is pushed forward of the base frame 6, or conversely, is pulled toward the base frame 6. Since the foot kneading device 5 is provided with the wheels 14 so as to roll on the floor surface F in the front-rear direction, the foot kneading device 5 is smoothly pushed out and pulled on the floor surface F.

  Further, the foot kneading device 5 is in a state where the wheel 14 can be used as a fulcrum to easily swing the upper end portion of the foot kneading device 5 in the front-rear direction. When the foot kneading device 5 is pushed forward, the foot kneading device 5 gradually rises up, and conversely, when the foot kneading device 5 is pulled back backward by the rocking arm 47 swinging backward. The foot massaging device 5 gradually tilts the upper part backward.

  As shown in FIG. 5, in the process in which the swing arm 47 swings forward, the foot kneading device 5 is in a relaxed posture (knees) such that a user sitting on the seat 2 throws his / her foot forward. Even in a posture in which the foot is extended to a certain extent), it is tilted backward and tilted up so that the foot can be easily put into the foot putting portion 13 of the massage surface 5a. Further, as the final stage in which the swing arm 47 swings forward, the user can stand upright at an upright angle that allows the user to easily put his / her leg even when the knee is bent at a right angle.

On the other hand, in the final stage of the process of swinging the swing arm 47 backward, as shown in FIG. 3, the foot massaging device 5 is tilted to a state where the back surface thereof faces the floor surface F and is brought close to the seat portion. 2 is housed in a lower storage position P.
As described above, the posture converting mechanism 16 having such a configuration is such that the swing arm 47 is connected between the seat portion 2 and the foot gripping device 5, and the swing arm 47 is swung. A posture driving unit 48 (electrical expansion and contraction mechanism) to be driven is provided between the base fulcrum 50 of the seat frame 2a and the rear member 36. That is, the seat 2 is the basis for supporting the foot massage device 5.

  Therefore, even if the seat part 2 moves back and forth or moves the front end of the seat part 2 up and down by the seat part moving mechanism 15 described above, the “relative distance between the seat part 2 and the foot gripping device 5” It is always held within the swing radius of the swing arm 47 as the center. In such a holding relationship, it can be said that the posture changing mechanism 16 makes the posture of the foot massage device 5 relative to the seat 2 variable.

  Here, the “relative distance between the seat 2 and the foot massage device 5” means that the user who sits on the seat 2 does not move the seating position or the seating posture with respect to the seat 2 one by one. If the leg is extended or the foot is lowered at the front part of the seat part 2, the distance relation is such that the foot can be put into the foot massage device 5 (the foot massage device 5 can be used as it is). For this reason, numerical strictness between the seat 2 and the foot massage device 5 is not required.

  Therefore, for example, as shown in FIG. 4, the seat 2 is moved forward while the foot kneading device 5 is stored in the storage position P below the seat 2, and the backrest 3 is operated in a reclining operation (in short, the foot 6 or a state in which the seat 2 is moved backward and the backrest 3 is reclining forward, as shown in FIG. The use status such as “Yes” can be freely selected according to the user's desire.

The operation | movement aspect of the chair type massage machine 1 which has the structure demonstrated above is demonstrated easily.
First, as shown in FIG. 3, the seat portion 2 is moved backward, the backrest portion 3 is set to the front reclining state, and the foot-clamping device 5 is stored in the storage position P below the seat portion 2. The foot massage device 5 in the storage position P has a bottom surface facing forward, a massage surface 5a facing upward, and a bottom surface substantially flush with the front end of the seat portion 2.

When the electric motor 30 of the seat portion moving mechanism 15 is operated from this state, as shown in FIG. 4, the lower end portion of the backrest portion 3 moves forward via the swinging portion 10 as the seat portion 2 moves forward. The backrest 3 is pulled out and performs a reclining operation so as to fall backward while lowering its upper end.
Therefore, the user sitting on the seat 2 in this state can sit in a relaxed posture by tilting the upper body backward.

The chair type massage machine 1 according to the second embodiment also has a seat portion 2 and a backrest portion 3 provided at the rear portion of the seat portion 2, and a foot massage device 5 is provided at the front portion of the seat portion 2. Therefore, the basic configuration is the same as that of the first embodiment.
The seat 2 is supported by the base frame 6 at a predetermined height, and the lower part of the backrest 3 is slidably supported around the axis in the left-right direction via the swinging part 10 to the rear of the seat 2. The point connected with the end part, the point where the massage part 9 etc. for performing the massage operation to the user seated on the seat part 2 are provided in the backrest part 3 and the seat part 2 or the left and right sides thereof. This is substantially the same as the first embodiment.

Furthermore, the chair type massage machine 1 has a configuration in which the seat portion 2 can be moved back and forth by the seat portion moving mechanism 15 and the back and forth movement of the seat portion 2 and the reclining operation of the backrest portion 3 are interlocked. It is substantially the same as that of the first embodiment in that the posture converting mechanism 16 allows the foot massaging device 5 to perform various posture changes.
The most different place of the chair type massage machine 1 of the second embodiment from the first embodiment is that the position of the guide portion 20 for guiding the seat portion 2 movably in the front-rear direction with respect to the seat portion moving mechanism 15. It is in. Further, the posture changing mechanism 16 itself has a lower arm member 72 and an intermediate link 73 in addition to the swing arm 47.

First, the difference between the guide portion 20 of the seat portion moving mechanism 15 and the first embodiment will be described.
As shown in FIG. 8, the guide portion 20 is configured by the lower frame 7 of the base frame 6. The lower frame 7 includes a pair of left and right side members 60 whose longitudinal direction is directed in the front-rear direction so as to be parallel to the left and right side members 24 of the upper frame 8, and rear end portions of the left and right side members 60. It has the rear member 61 which connects each other.

The left and right side members 60 are provided so that the front half is inclined in the front rising direction with a substantially central portion in the front-rear direction as a boundary (front rising inclined portion), and the rear half is parallel to the floor surface F (rear horizontal). Part). The side member 60 is formed of a square pipe or the like having a hollow quadrangular cross section in the first half and the second half.
On the other hand, the seat frame 2a is provided with a leg frame 63 that fits into the base frame 6 (between the left and right side members 24). The leg frame 63 has a total of four leg members 64 that are separated from each other in the front-rear direction and the left-right direction, and a bridging member 65 is provided so as to bridge the lower ends of the leg members 64.

Sliding portions 67 and 68 (externally fitted to the side member 60 and slidable in the longitudinal direction of the side member 60 (that is, the front-rear direction) are provided at the front and rear positions of the crossover member 65. A front sliding part 67 and a rear sliding part 68) are provided.
The front sliding portion 67 is arranged so as to slide back and forth in a region (front rising inclined portion) that is inclined forwardly in the front half of the side member 60, and the rear sliding portion 68 is a side member 60 is arranged so as to slide back and forth in a horizontal region (rear horizontal portion) in the latter half.

As described above, the side member 60 of the lower frame 7 constituting the base frame 6 can hold the front sliding portion 67 and the rear sliding portion 68 provided on the seat frame 2a so as to be slidable in the front-rear direction. Thus, the guide portion 20 is configured.
With the configuration of the guide portion 20, when the seat portion 2 moves forward, the more the seat portion 2 moves forward, the more the front end of the seat portion 2 rises, while the seat portion 2 moves backward, The more the seat 2 is moved backward, the more the front end of the seat 2 is lowered.

However, unlike the case of the first embodiment, the upward movement of the seat portion 2 is caused only by the front sliding portion 67 (the rear sliding portion 68 has a constant height regardless of the sliding position). Therefore, even if the seat part 2 moves forward, the rear part of the seat part 2 does not rise, and as a result, the higher the seat part 2 moves, the greater the difference in height between the front part and the rear part of the seat part 2 The situation is obtained.
Note that the advance / retreat drive unit 21 that moves (drives) the seat 2 in the front-rear direction with respect to such a guide unit 20 employs an electric feed screw mechanism as in the first embodiment. That is, a feed screw shaft 31 that is rotationally driven by the electric motor 30 is attached to the lower frame 7 of the base frame 6 in a forward projecting state, and a nut member 32 that is screwed into the feed screw shaft 31 is attached to the shaft of the feed screw shaft 31. It is held by a transition member 65 provided on the leg frame 63 of the seat frame 2a while being unable to rotate around.

As described above, the guide portion 20 has a horizontal region in the rear half thereof, and the nut member 32 is held at a close position in the front-rear direction with respect to the rear sliding portion 68 that moves along the horizontal region. ing. Therefore, the feed screw shaft 31 does not need to be inclined in the forward upward direction and is provided horizontally.
Next, a difference between the posture conversion mechanism 16 that changes the posture of the foot massage device 5 and the first embodiment will be described.

As described above, the posture changing mechanism 16 according to the second embodiment includes the swing arm 47 for connecting the seat portion 2 and the foot kneading device 5 and the posture drive unit 48 for driving the swing arm 47 to swing. And have. Further, the posture conversion mechanism 16 has a lower arm member 72 and an intermediate link 73.
Each of the swing arm 47, the lower arm member 72, and the intermediate link 73 is provided in a pair of left and right (two). Among the swing arm 47, the lower arm member 72, and the intermediate link 73, the intermediate link 73 is provided on both the left and right side portions of the foot massage device 5.

A reversal fulcrum 75 is formed in the middle portion of the intermediate link 73 for supporting the swinging device 5 around the axis in the left-right direction. The intermediate link 73 has a structure in which connecting end portions 76 and 77 protrude from the reversal fulcrum 75 in two opposite directions.
As shown in FIG. 7, the seat frame 2 a is provided with a pair of left and right bracket pieces 78 that protrude diagonally forward and downward from the left and right swinging units 10. The bracket piece 78 is provided with a base fulcrum 50 that supports the swing around the shaft center direction in the left-right direction, and the base end of the swing arm 47 is connected through the base fulcrum 50. ing. The tip end portion of the swing arm 47 thus provided and one end portion (one connecting end portion 76) of the intermediate link 73 are connected to each other via a tip fulcrum 51 so as to be swingable.

  On the other hand, the lower arm member 72 extends downward from the base fulcrum 50 of the seat portion 2 and then bends forward so as to protrude forward, and the front protrusion 87. And an expansion / contraction flange 81 that is slidable forward. And the front-end | tip part of the expansion / contraction collar part 81 provided in this way and the other end part (other connection end part 77) of the intermediate link 73 are connected through the auxiliary | assistant fulcrum 82 so that rocking | fluctuation is possible.

  For this reason, the foot massaging device 5 is rotatable around the reversal fulcrum 75 of the intermediate link 73, and as shown in FIGS. 9 and 10, the massage surface 5a faces upward, as shown in FIG. And as shown in FIG. 14, it becomes reversible between the state which the massage surface 5a faces the floor surface F (it can turn over). Moreover, in the middle of this reversal, as shown in FIGS. 11 and 13, the massage surface 5a can be in a state of facing forward.

In a state where the massage surface 5a faces the floor surface F, the back surface 5b of the foot massage device 5 faces upward. That is, since the foot insertion portion 13 does not face upward, the user sitting on the seat portion 2 can throw his / her foot forward and place it on the back surface 5 b of the foot massage device 5.
As in the first embodiment, the posture driving unit 48 employs an electric feed screw type expansion / contraction mechanism (a mechanism for extending and contracting the feed screw shaft 56 from the cylinder unit 55 by the electric motor 57). It is.

  By actuating this posture drive unit 48, the foot kneading device 5 is pushed forward of the base frame 6, or conversely, pulled toward the base frame 6. Further, when the swing arm 47 swings forward and the foot kneading device 5 is pushed forward, the foot kneading device 5 gradually raises the upper part, and on the contrary, the swing arm 47 swings backward. Thus, when the foot kneading device 5 is pulled back, the foot kneading device 5 gradually tilts the upper part backward. These are substantially the same as in the first embodiment.

When the swing arm 47 is swinging forward, and when the foot kneading device 5 is moved forward from the storage position P below the seat 2, the telescopic hook 81 of the lower arm member 72 protrudes forward. On the contrary, when the swing arm 47 swings backward and when the foot kneading device 5 enters the storage position P, the telescopic hook 81 of the lower arm member 72 contracts backward. To do.
Thus, since the foot massaging device 5 is held by the lower arm member 72, in the second embodiment, wheels for rolling in the front-rear direction on the floor surface F with respect to the foot massaging device 5 (see FIG. It is not necessary to provide 2) and the like, and structural simplification and weight reduction are achieved as compared with the first embodiment.

  By the way, in 2nd Embodiment, in the guide part 20 for guiding the back-and-forth movement of the seat part 2, the inclination angle | corner which raises ahead is larger than the guide part 20 of 1st Embodiment (steep inclination). Moreover, as described above, a structure is adopted in which the height difference between the front part and the rear part of the seat part 2 increases as the seat part 2 advances. Therefore, as the seat 2 moves forward and the backrest 3 falls backward, the height of the head and waist of the user sitting on the seat 2 approaches the height of the heart. This makes it difficult for blood to collect at the end portion of the user's lower limbs, and has an advantage of being beneficial not only for the massage effect but also for recovery from fatigue. In this case, it goes without saying that a higher effect can be obtained if the foot kneading device 5 protrudes forward to support the lower limbs of the user.

In the second embodiment, other configurations, operating conditions, effects, and the like are substantially the same as those of the first embodiment. The detailed explanation of is omitted.
