This massage machine is of a chair type, and comprises a seat 1, a backrest 2, a footrest 3, a base 4, a frame 5, an armrest 6, at least a seat 1, a backrest 2, and a footrest. A treatment unit (not shown) is provided on any of the tables 3 and performs treatment for the user. In this massage machine, the seat 1 is changed so that the angle of the seat 1 changes in accordance with the change in angle of the backrest 2 due to reclining.
And the backrest 2 are connected by a link mechanism (not shown in FIG. 1) as an interlocking means. In addition, the seat 1 and the footrest 3 are integrally continuous, and the footrest 3 moves according to the seat 1.

In this massage machine, since the seat 1 also moves in conjunction with the backrest 2, the posture of the lower body can be changed by reclining. The treatment means is not shown, but may be a pair of fir balls provided on the backrest 2 so as to be movable in the vertical direction, for example, as in the conventional massage machine. A massage machine according to claim 2 is shown in FIG. However, the same elements are denoted by the same reference numerals. In this massage machine, the seat 1 and the backrest 2 are connected by a link mechanism (interlocking means) such that the angle change of the seat 1 is smaller than the angle change of the backrest 2. Here, the link mechanism includes a support fitting 10 fixed to the back surface of the seat 1, a link 11 having one end rotatably connected to the support fitting 10, and a support fitting fixed to the lower end surface of the backrest 2. And a link 13 having one end rotatably connected to the support fitting 12. Link 11
Is rotatably connected to substantially the center of the link 13. The link 13 has an elongated hole 13a at the other end,

A pin is used to connect the link 13 and the link 13 and the link between the link 13 and the frame 5, and each member is rotatably supported by the pin.

With this link mechanism, when the backrest 2 is inclined downward as indicated by the dotted line, each link 1
As a result of the movement of the seat members 1 and 13 as indicated by the dotted lines, the seat 1 also inclines upward as indicated by the dotted lines. At this time, the angle between the back surface of the backrest portion 2 before the inclination and the front surface of the backrest portion 2 after the inclination is θ ₁ , the seat surface (upper surface) of the seat portion 1 before the inclination and the seat portion 1 after the inclination.
When the angle formed between the back surface of the theta _2, theta _1> theta _2, and the angle change of the seat 1 becomes smaller than the angular change of the backrest portion 2. As a result, the seat 1 is linked with the backrest 2.
In addition to the movement of the body, the movement of the seat 1 is smaller than the movement of the backrest 2, so that the posture of the lower body can be changed and the angle between the upper body and the lower body can be changed.

A massage machine according to claim 3 is shown in FIG. In this massage machine, the seat 1 and the backrest 2 are connected by a link mechanism such that the angle of the seat 1 changes when the backrest 2 changes by a certain angle or more. The link mechanism includes a support fitting 20 fixed to the back surface of the seat 1, a support fitting 21 fixed to the lower end face of the backrest 2, and a pin 2 at one end through an elongated hole 22 a.

According to this linkage, when fallen from the state of the angle theta ₀ backrest 2 is most up until an angle theta _1, the link 22 is moved as shown by a dotted line, the link 2
The pin 23 connecting one end of the support member 20 to the support fitting 20 only moves relatively in the elongated hole 22a with respect to the movement of the link 22, but the seat 1 does not move, and the angle of the seat 1 is kept constant. Up to.

As shown in FIG. 4, when the backrest 2 is further tilted from the angle θ ₁ to the angle θ ₂ , the pin 23 hits the end of the elongated hole 22a, and the link 22 pushes the pin 23, so that the seat 1 is moved. In conjunction with the backrest 2, the angle of the seat 1 changes according to a change in the angle of the backrest 2. As a result, not only the seat 1 moves in conjunction with the backrest 2 but also
If the backrest 2 does not move beyond a certain angle, the seat 1 does not move, so that the posture of the lower body can be changed and the angle between the upper body and the lower body can be changed.

In the embodiment shown in FIGS. 3 and 4,
The angles θ ₀ , θ ₁ , and θ ₂ may be set to the most appropriate values based on ergonomics. For example, the angle θ ₀ [the angle on the obtuse side formed by the horizontal plane and the front (or back) of the backrest 2 ]
Is 115 °, angle θ ₁ is 140 °, angle θ
₂ (same) is 165 °. The massage machine according to claim 4 is shown in FIG. 5 (side view) and FIG.

This massage machine automatically moves from the second lumbar vertebra to the position corresponding to the third lumbar vertebra of the user when the massage pad as the treatment means stops the massage function by the massage pad. That is, the pair of fir balls 7 provided on the backrest 2 so as to be movable in the up-and-down direction is a dash-dot line in a range from the buttocks (lowest point) 7a of the user M to the neck (highest point) 7b. When the user M moves along, but does not operate the fir ball 7 (when used as a mere ordinary chair without using the massage function), the user M is almost at a position corresponding to the second to third lumbar vertebrae (solid line). Section). In this case, when the massage machine is simply used as a chair, the massage ball 7 hits the waist of the user M, and the waist is supported by the massage ball 7, so that the lower back pain is unlikely to occur.

FIG. 8 (a) (a schematic side view of a main part) shows a massage machine according to claim 6, and FIG. 8 (b) shows related parts in a conventional massage machine for reference. In this massage machine, the foot rest 3 swings on the seat 1 so that the foot rest (upper surface) is substantially flush with the seat surface (upper surface) of the seat 1 when the foot rest 3 is raised. It is connected as possible. In FIG. 8A, a front portion 1a of the seat portion 1 has, for example, a shape as shown in the figure, and a footrest 3 is swingably connected to the front portion 1a by a fulcrum 1b. That is, by positioning the fulcrum 1b on the front side and the upper side of the seat 1, when the footrest 3 is raised, the footrest 3 becomes almost the same height as the seat 1 (see a dotted line portion). That is, since the feet and buttocks of the user are almost at the same height, fatigue of the feet can be prevented.

By the way, in the conventional case shown in FIG. 8B, the fulcrum 1b 'connecting the seat 1 and the footrest 3 is not located in front of the seat 1, and Since it is located on the lower side, even if the footrest 3 is raised, the footrest 3 remains lower than the seat portion 1 (see the dotted line), and the legs become tired when sitting long. FIG. 9 shows a specific example of the mechanism shown in FIG.
(A perspective view with the exterior of the seat 1 and the footrest 3 removed)
Shown in Here, metal fittings 30 are fixed to both sides of the front end of the seat 1, and a projection 3 a is provided on the footrest 3 corresponding to the metal fitting 30, and a shaft 31 attached to the projection 3 a can be rotated by the metal fitting 30. Supported. As a result, the fulcrum 1b is divided on both sides of the seat 1, so that the seat surface of the seat 1 is substantially prevented from becoming longer due to the presence of the footrest 3, so that the back side of the user's knee can be moved. No more pressure.

A massage machine according to claim 7 is shown in FIG. In this massage machine, the footrest 3 is connected to the seat 1 and the backrest 2 by a link mechanism (interlocking means) so that the footrest 3 moves up and down in conjunction with an angle change due to reclining of the backrest 2. I have. This link mechanism has a support fitting 40 fixed to the back surface of the seat 1, one end rotatably connected to the support fitting 40, and the other end slidable and rotatable into an elongated hole 3 b formed in the footrest 3. , A support fitting 42 fixed to the lower end surface of the backrest 2, and one end rotatably connected to the support fitting 42, and the other end into an elongated hole 43a.

According to this link mechanism, when the backrest 2 is raised, the link 41 is pulled by the link 44 depending on the position of the link 43, and the other end of the link 41 is
, The footrest 3 tilts downward. On the other hand, when the backrest 2 falls down as indicated by the dotted line, the link 41 is pushed by the link 44 as the link 43 moves toward the seat 1, and the footrest 3 is pushed up while the link 4 is pushed up.
The other end of 1 relatively moves in the elongated hole 3b. Then, in a state where the backrest 2 is tilted to the maximum, the other end of the link 41 is located on the other end side of the elongated hole 3b, and the footrest 3 reaches the highest position (see a dotted line portion). In other words, when the backrest 2 is tilted, the footrest 3 is raised accordingly, so that the feet do not drop during reclining, and fatigue can be prevented.

The massage machine according to claim 8 is shown in FIG. 11 (a schematic side view of a main part in a state where the footrest 3 is turned down) and FIG.
(Schematic main part side view with footrest 3 raised). This massage machine is connected to the seat 1 by a link mechanism (interlocking means) so that the footrest 3 moves forward of the seat 1 when the footrest 3 is raised. The link mechanism includes a support fitting 50 fixed to the back surface of the seat 1, an L-shaped arm 51 a, a handle 51 rotatably connected to the support fitting 50, and a frame 52 of the footrest 3. A fixed support fitting 53, a link 54 having one end rotatably connected to the support fitting 53 and the other end rotatably connected to the arm 51a, and a long hole 55a connected to the frame 52 and A nucleus (projection) 56 provided on the seat 1 is composed of a slider 55 inserted into the elongated hole 55a, and a connecting cloth 57 covering a connecting portion between the seat 1 and the footrest 3.

Since the handle 51 has the bent portion of the arm 51a connected to the support fitting 50, when the handle 51 is pushed down on the footrest 3 as shown in FIG.
When the link 1a rotates downward and the link 54 is pulled downward, the footrest 3 falls down. In this state, the slider 55 is pushed rearward by the frame 52 and
Corresponds to one end (left end) of the long hole 55a.

On the other hand, as shown in FIG.
When 1 is completely raised to the front, the arm 51a rotates upward, and the link 54 is pushed upward, so that the footrest 3 is raised. In this state, the slider 55 is pulled forward by the frame 52, and the nucleus 56 hits the other end (right end) of the elongated hole 55a. In this case, when the footrest 3 is raised by the handle 51, the footrest 3 becomes almost the same height as the seat 1 (the seating surface of the seat 1 and the footrest of the footrest 3 are almost flush with each other). At the same time, the footrest 3 is moved to the front of the seat 1 to be substantially longer, so that fatigue of the foot can be prevented.

FIG. 13 (schematic side view) shows a massage machine according to a ninth aspect. This massage machine has a backrest 2
The upper part 2a can be changed in angle relative to a part other than the upper part 2a, and bends in a direction opposite to the inclination direction in conjunction with an angle change due to reclining of the backrest part 2. Here, the main pulley 6 is located below the backrest 2.
0 is rotatably provided, and the pulley 61 is rotatably provided near the boundary between the upper portion 2a and other portions. The main pulley 60 is attached to a rotation shaft (not shown) rotatably supported at a connection portion between the backrest 2 and the frame 5. A belt 62 is wound around the pulleys 60 and 61, and the pulley 61 rotates according to the rotation of the pulley 60. Further, the diameter of the slave pulley 61 is set to be larger than the diameter of the main pulley 60, and the rotation of the slave pulley 61 is smaller than the rotation of the main pulley 60.

Further, although not shown in FIG. 13, a switching mechanism for fixing / releasing the angle change of the upper portion 2a is provided at an appropriate position (for example, on the side of the frame 5). The switching mechanism is, for example, a mechanism that fixes and releases the main pulley 60 with respect to the rotating shaft. In this massage machine,
When the upper portion 2a is moved integrally with the backrest 2 by operating the switching mechanism, the belt 6 can be moved even if the backrest 2 is tilted.
2 does not rotate, so that the upper part 2a falls down integrally with the backrest part 2. In this state, fir balls (not shown) provided on the backrest portion 2 are likely to hit the back from the neck of the user.

On the other hand, when the switching mechanism is operated to set the upper portion 2a to move relative to the backrest 2,
When the backrest 2 is tilted, the main pulley 60 rotates according to the inclination angle, and the sub pulley 61 is rotated by the belt 62 in the arrow direction. As a result, the upper portion 2a bends in a direction opposite to the inclination direction in conjunction with the change in the angle of the backrest portion 2 (the upper portion 2a rises according to the inclination of the backrest portion 2). In this case, since the upper part 2a is raised according to the inclination angle of the backrest part 2, the part above the user's chest is supported in the reclined state, and the posture of the user is stabilized ergonomically and it becomes easy. .

The rotation angle of the upper portion 2a with respect to the inclination angle of the backrest 2 is as follows. Main pulley 60
Is the diameter of d1, the diameter of slave pulley 61 is d2, and the rotation angle of main pulley 60 is θ1, and the rotation angle θ2 of slave pulley 61 is
Is represented by the following equation. θ2 = θ1 × (d1 / d2) Therefore, for example, if the diameter of the slave pulley 61 is twice as large as the diameter of the main pulley 60, the slave pulley 61 (upper part 2a) becomes
0 (backrest portion 2) rotates by an angle of 1/2 of the rotation angle. Therefore, as the diameter of the slave pulley 61 approaches the diameter of the main pulley 60, the rotation angle of the upper portion 2a increases.

In the above embodiments, each characteristic configuration is described. However, if possible, the respective configurations may be combined. For example, the link mechanism shown in FIGS. 11 and 12 is combined with the rotation mechanism above the backrest shown in FIG. 13, or the link mechanism shown in FIG. 2 or FIG.
1 and the link mechanism shown in FIG. 12 may be combined with each other, thereby obtaining a combined effect.
