[0003]

The chair-type massager is heavy and large due to its structure, so that it is usually used on a floor or the like, but when it is not used, it takes up space and becomes an obstacle. In view of this, if you give a chair with a folding function a massage function,
Although it is light and convenient to carry, if the massage mechanism built into the above-mentioned chair type massage device is provided in the backrest part of the seat chair, the backrest part becomes large as well as heavy, making it inconvenient to carry, During use, the backrest can easily fall backward. Further, since the massage mechanism of the chair-type massage device is expensive, an inexpensive seat-chair massage device cannot be realized even if this massage mechanism is incorporated in a chair.

[0004] On the other hand, the size and weight of the backrest portion of the chair are reduced while the upper portion of the backrest portion (the portion facing the neck portion).
In order to be able to move the treatment element in the massage mechanism, it is necessary to reduce the size and weight of the massage mechanism.
The massage mechanism used in the chair type massage device is almost impossible in terms of structure and cost. The present invention has been made in view of such a problem, and it is possible to suppress an increase in the size and weight of the backrest even when incorporated into the backrest, and to obtain a sufficient massage effect as compared with the conventional monotonous massage. It is an object of the present invention to provide a chair massager provided with a massage mechanism that can be used.

The support 11 is inserted into the back of the movable base 30 and guides the movement of the movable base 30. Two guide shafts 13 are inserted through the back of the movable base 30 and screwed into the movable base 3.
The shaft 13 has an end plate 17 that supports both ends of the shafts 13 and 14. Both ends of the guide shaft 13 are inserted through insertion holes formed in the end plate 17, and are fixed so as not to come off by, for example, caulking. Both ends of the screw shaft 14 are rotatably supported by bearings 18 attached to an end plate 17. Screw shaft 14 is movable table 30
The movable table 30 moves with the rotation of the screw shaft 14. Although not shown in the drawings of FIGS. 4 to 6, the guide shaft 13 is inserted into two U-shaped insertion portions 32 (see FIG. 14) protruding side by side on the rear side of the movable base 30, and is movable.

A large pulley 25 is attached to a portion of the screw shaft 14 projecting from the end plate 17 corresponding to the small pulley 24, and a belt 26 is hung on both pulleys 24, 25. Therefore, when the motor 12 operates, the screw shaft 14 rotates through both the pulleys 24 and 25 and the belt 26.

Although not shown in the drawing, a curved slit is formed in the plane of the large pulley 25, and a photoelectric sensor 28 is disposed facing the slit, and the photoelectric sensor 28 is attached to the end plate 17. Is mounted on the mounted circuit board 29. The rotation of the motor 12 is detected by the photoelectric sensor 28 and the slit, and the current position of the movable base 30 is detected based on the rotation. Although not shown in the drawings, upper and lower micro switches for regulating the vertical movement range are provided on the upper and lower sides of the movable table 30 in the vertical direction, and the upper and lower end plates 17 are provided. Is mounted with a block piece for turning on the microswitch.
Therefore, when the movable base 30 moves up or down, and the upper limit micro switch is turned on by the corresponding block piece, and conversely, when the lower limit micro switch is turned on by the corresponding block piece, Then, the movement of the movable base 30 stops.

The movable base 30 includes a pair of rotating plates 35 and 36 rotatably supported, respectively.
In FIG. 6, one treatment element 37, 38 is provided at a position eccentric from the rotation center of each of the rotating plates 35, 36. In this embodiment, the upper part of the movable base 30 is located forward and the lower part is located rearward such that the moving plane (rotation plane) of the treatment elements 37 and 38 is inclined with respect to the vertical movement plane of the movable base 30. In other words, the movable base 30 has the guide shaft 13 and the screw shaft 1 with the front surface facing obliquely.
4 attached.

FIG. 7 is a cross-sectional view of the movable base 30 at the center, FIG. 8 is a partially broken plan view, and FIG. 9 is a longitudinal cross-sectional view of the movable base 30 at the center. However, in FIGS. 8 and 9, two treatment elements 37 are provided on each of the rotating plates 35 and 36. A motor 40 for rotating the treatment elements 37 and 38 is fixed to the back side of the movable base 30, and a small pulley 41 is attached to a rotation shaft 40 a thereof. Are arranged, and a belt 43 is hung on both pulleys 41 and 42. The large pulley 42 is attached to one end of a worm 45 disposed in the transverse direction at the center of the movable portion 30, and both ends of the worm 45 are provided with bearings 46.
And rotatably supported.

Further, the worm 45 is
Are engaged with worm gears 50 and 51 rotatably arranged on both sides (left and right) with the shafts 54 and 55 fixed at the centers of the worm gears 50 and 51. It is rotatably supported by the bearings 52 and 53. In addition, the rotary plates 3
5, 36 are attached. Therefore, when the motor 40 operates, the small pulley 41, the belt 43, the large pulley 42,
Worm 45, worm gears 50 and 51, shafts 54 and 55
, The rotating plates 35 and 36 rotate in directions opposite to each other.

The treatment element 3 protruding from the rotating plates 35 and 36
7 and 38 have mounting shafts 37a and 38a, respectively, and these mounting shafts 37a and 38a are inserted into mounting holes formed in advance in the rotating plates 35 and 36, and are fixed by, for example, fixing rings so as not to come off. A plurality of (here, 16) circular holes 36b are provided at equal angular intervals (22.5 °) from the center of rotation at the peripheral edge of one of the two rotating plates 35, 36. A photoelectric sensor 60 is arranged on the movable base 30 corresponding to these circular holes 36b,
Is mounted on a circuit board 61 attached to the movable base 30. With the photoelectric sensor 60 and the circular hole 36b, the rotational positions of the rotating plates 35, 36, that is, the positions of the treatment elements 37, 38 can be detected. Here, position detection means is constituted by the circular hole 36b of the rotating plate 36, the photoelectric sensor 60, and the like.

In the massager of the above embodiment, the power of the motor 40 for rotating the treatment elements 37 and 38 is supplied to the worm 45 through the small pulley 41, the belt 43 and the large pulley 42.
However, the rotation of the motor 40 may be directly transmitted to the worm 45. FIG. 10 shows a plan view of the movable base 30 in that case, and FIG. 11 shows a cross-sectional view at the center. Here, the motor 40 is fixed to the side surface of the movable base 30 at the center of the movable base 30, and the rotating shaft 40a of the motor 40 is directly connected to the worm 45 by a shaft coupling. In this case, components such as pulleys and belts are not required.

On the other hand, in the embodiment shown in FIGS. 10 and 11,
Two large and small treatment elements 37 are provided on the rotating plates 35 and 36, respectively.
A, 37B, 38A, 38B are provided. Also,
A circular hole 35b is formed in the periphery of the rotating plate 35, and the photoelectric sensor 60 is arranged corresponding to the circular hole 35b. The movable table 30 has a vertically moving plane and the treatment elements 37A, 37A.
This is an example in which the rotation planes of B, 38A and 38B are parallel.

In the massage mechanism configured as described above,
As described above, when the motor 12 operates, the screw shaft 14 rotates, and the movable base 30 moves up and down. When the motor 40 operates, the treatment elements 37 and 38 rotate on a circular orbit as the rotating plates 35 and 36 rotate. In other words, the treatment elements 37 and 38 rotate in the same plane for each of the rotating plates 35 and 36. By the combination of the vertical movement of the movable table 30 and the rotation of the treatment elements 37 and 38, a complicated massage can be applied to the back of the user, and a sufficient treatment effect can be obtained. Moreover, since the structure is simple, the massaging mechanism can be reduced in size and weight at low cost, and the chair incorporating the massaging mechanism does not have to be so heavy and large.

The above-mentioned massage mechanism can perform various structural changes and operation control of the treatment element. Each component will be described below. First, since the massage mechanism is incorporated in the backrest 1 of the chair, the degree of protrusion of the treatment element is important. In FIG. 12, the protruding height H of the treatment element 37 from the rotating plate 35 is set to 40 mm or less, depending on the size of the treatment element 37 and the like. FIG.
3, the protrusion height H and the rotation diameter R of the treatment element 37
Is set to H / R <1. These set values are considered for a chair with a built-in massage mechanism. If the set values are larger than the above values, the thickness of the massage mechanism increases, and the backrest 1 and the seat 2
Can not be folded sufficiently, and the inconvenience of carrying is felt.

On the other hand, when the rotation plane of the treatment elements 37 and 38 is parallel to the vertical movement plane of the movable table 30, the treatment elements 37 and 38
Irrespective of the rotation position of the treatment element 38, the treatment elements 37 and 38 come into contact with the back of the user with a substantially constant pressing force, but the rotation plane of the treatment elements 37 and 38 (the movement plane of the treatment element) When the movable table 30 is inclined with respect to the vertical movement plane, the pressing force can be changed strongly depending on the rotational position of the treatment elements 37 and 38. FIG. 14 shows a form example in this case.
To FIG.

The configuration shown in FIG. 14 corresponds structurally to FIG. 11, but when the rotation axis direction of the motor 40 is inclined by an angle θ1 with respect to the moving direction of the movable base 30 (a), And (b) when tilted by the angle θ2.
In the case of FIG. 14A, the upper part of the movable base 30 is located rearward,
The lower part is located forward, and in the case of FIG. 14B, the upper part is located forward and the lower part is located backward. In any case, the movable platform 30 is provided with an inclined platform 30 ', and the inclined platform 30'
Thereby, the inclination angle and the inclination direction can be easily and arbitrarily set. The angles θ1 and θ2 are not particularly limited, but may be set to appropriate angles in a range of about 5 to 15 °.

FIGS. 15 and 16 show a treatment element 37,
This is the case where each of the rotation planes 38 intersects. 15 and 16, the movable table 30 is bent at the worm 45 such that the treatment elements 37 and 38 on both sides face outward and inward, respectively, with the worm 45 of the movable table 30 as a boundary. Further, the inclination modes of FIGS. 14A and 14B and the inclination modes of FIG. 15 or FIG. 16 may be combined.

When the oblique mode as shown in FIGS. 14 to 16 is employed, the force for pressing the back of the human body changes according to the rotational position of the treatment element, which is shown in FIG. FIG. 17A shows a case where the rotating plate 35 provided with the treatment element 37 is in the inclined form shown in FIG. 14B (the upper part of the movable base 30 is located forward and the lower part is located backward). FIG. 17B is a graph showing the relationship between the rotational position of the treatment element and the pressing force obtained in that case. According to this, the pressing force when the treatment element 37 is first at the position A is normal, but when the rotating plate 35 rotates in the direction of the arrow and the treatment element 37 comes to the position B, the movable table 30 moves up and down. Since the amount of treatment of the treatment element 37 with respect to the moving plane is maximized, the pressing force is the strongest.
Then, at the position C, the normal pressing force is applied again, and the treatment element 3
When 7 reaches the position D, the amount of protrusion of the treatment element 37 is minimized, so that the pressing force is minimized. By repeating such a change in the pressing force, the stimulus to the human body is not monotonous, and the massage effect is further enhanced.

On the other hand, in the example of FIG.
When the individual treatment elements 37A and 37B are provided at an angular interval of 180 °, the large treatment element 37A has normal rigidity (for example, made of plastic), whereas the small treatment element 37B has an elastic body ( For example, rubber). In this case, first, the treatment elements 37A and 37B are moved to the positions A and 37, respectively.
When the position is at c, the pressing force is both normal, but when the treatment elements 37A and 37B reach the positions B and d, the treatment element 37A
(Solid line) is the strongest, and the pressing force (dotted line) of the treatment element 37B is the weakest. When the treatment elements 37A and 37B reach the positions D and b, the pressing force of the treatment element 37A becomes the weakest and the pressing force of the treatment element 37B becomes the strongest at the positions C and a. Here, the treatment element 37A is the treatment element 37.
Since it is larger and harder than B, the change in the pressing force is more remarkable in the treatment element 37A.

Alternatively, for example, if the treatment elements 37A and 37B are alternately moved by 180 ° in the range of the positions B and d and the positions D and b, that is, the treatment elements 37A and 37B can be swung within a certain angle range. For example, two different “fir” feelings can be obtained. On the other hand, in addition to continuously rotating the treatment element, that is, the rotating plate in the same direction at the same speed, the rotating plate may be rotated in the reverse direction or the rotation speed may be changed to a large or small value. FIG. 19 shows an example of the treatment element driving circuit (the same applies to the movable base driving circuit) in that case. 19 includes a motor 40, a power supply (AC100V) 70, and a bridge circuit 7 for full-wave rectification.
1, a zero cross detection circuit 72, a CPU 73, a firing pulse generation circuit 74, a thyristor 75, a switching circuit 76, and a position detection circuit 77.

According to this drive circuit, the rotational position of the motor 40 (that is, the rotational positions of the rotating plates 35 and 36) is detected by the position detecting circuit 77 and is taken into the CPU 73. CPU73
Knows the positions of the treatment elements 37 and 38 from the position signals, and outputs a phase control signal corresponding to the positions to the firing pulse generating circuit 74 and a forward / reverse switching signal to the switching circuit 76 according to a preset program. , The rotation speed and the rotation direction of the treatment elements 37 and 38 are controlled.

By using a driving circuit as shown in FIG.
The treatment element is not only continuously rotated at the same speed, but also rotated in the opposite direction at an arbitrary rotation position, rocked in a certain angle range, and rotated quickly at a certain angle,
By performing various rotations or rotating directions in other angles at various angles, the treatment element can perform various treatment operations. As a result, it is possible to perform a sharp treatment operation such as a massager performs,
It is possible to further enhance the massage effect.

Further, by combining the above-described various rotation forms of the treatment element with the up and down movement of the movable table 30, a more varied massage can be performed. An example is shown in FIG.
Shown in In (a) of FIG. 20, one treatment element 37, 38 is provided on each of the rotating plates 35, 36, and the treatment elements 37, 38 are first located at positions facing the waist, and the movable table 30 is moved therefrom. In this case, the rotating plates 35 and 36 slowly move in the direction of the arrow and eventually move to a position corresponding to the neck as the ascending rises. At this time, since the treatment elements 37 and 38 move along the locus indicated by the dotted line, massage such as stretching the back can be performed.

In FIG. 20B, two treatment elements 37 and 38 are provided on the rotating plates 35 and 36, respectively, and the rotating plates 35 and 36 do not rotate as the movable table 30 moves up. This is the case when moving from the waist to the neck. At this time, four points can be pressed simultaneously along the spine. Alternatively, by rotating the rotating plates 35 and 36, the width of the “strip” can be changed, or the number of lines (the number of points) of the “strip” can be reduced by two.
Or 4 can be set freely. (A) of FIG.
(B) In any case, a complex massage that touches the back can be performed by combining reciprocation (up and down) of the operation, repetition at an arbitrary position, and variable speed.

On the other hand, in the above embodiment, the power of the motor 40 for rotating the treatment element is supplied to the pulleys 41 and 42 and the belt 43.
When transmitting to the worm 45 by (see FIGS. 7 and 8),
Although the case where the power is transmitted directly to the worm 45 (see FIGS. 10 and 11) is shown, the preferred embodiment is the former case. That is, as shown in FIG. 21A, when the motor 40 is attached to the side surface of the movable base 30, the distance L1 from the center of the treatment element 37 to the lower end of the movable base 30 is equal to the length L3 of the motor 40. Since the length of the movable base 30 is increased by the distance, the space required in the vertical direction of the movable base 30 is increased. If the motor 40 projects downward, the back may hit the motor 40.
In particular, when the movable base 30 has an inclined form as shown in FIG. 14A, the possibility that the back hits the motor 40 increases.

On the other hand, as shown in FIG. 21B, when the motor 40 is provided on the back side of the movable base 30 (on the side opposite to the protruding side of the treatment element 37), the treatment element 37 The distance L2 from the center to the lower end of the movable base 30 is shorter than the distance L1, so that the space required for the movable base 30 in the vertical direction can be reduced, and the back does not hit the motor 40.

Further, since the motor 40 and the worm 45 are connected by the pulleys 41 and 42 and the belt 43, the motor 40
Noise can be suppressed as compared with the case where the worm 45 and the worm 45 are directly connected. For example, assuming that the rotation speed of the motor 40 is 4000 rpm, when the worm 45 is directly connected to the motor 40, the rotation speed of the worm 45 also becomes 4000 rpm, and the worm 45 and the worm gears 50 and 51 having this rotation speed mesh with each other. Noise is relatively loud. However, in the case of belt driving, if the size ratio of the pulleys 41 and 42 is set to, for example, 1: 4, the rotation speed of the pulley 42 becomes 1000 r.
pm, and the number of revolutions of the worm 45 can be reduced to 1/4.

Further, in each of the above-described embodiments, the rotating plates 35 and 36 are driven by one motor 40. However, dedicated motors may be provided and driven independently. FIG. 22 shows an example of this case. In FIG. 22, motors 40A and 40B are attached to two movable tables 30A and 30B, respectively. The power of the motors 40A, 40B is transmitted to the rotating plates 35, 36 by, for example, gears 65, 66 meshing with inner gears provided inside the movable bases 30A, 30B. Although not shown in the drawings, the movable table 30
A and 30B are both attached to one movable base, and move up and down at the same time.

With such a configuration, the treatment elements 37, 3
Not only can 8 be rotated in the same direction, but also the speed of rotation can be varied between one and the other. Furthermore, the inclination angles of the movable tables 30A and 30B can be set individually. Therefore, although the number of components is increased, it is possible to cause the treatment element to perform a more complicated treatment operation.

[0037]

The seat and chair massager according to the first and second aspects of the present invention has the following effects because it is configured as described above. (1) Vertical movement / movement speed of movable table and treatment operation speed / treatment operation of treatment element (treatment within treatment movement trajectory) Range / treatment operation

Is obtained. (2) Even if the massage mechanism is incorporated in the backrest, the size and weight of the backrest can be suppressed, so that the chair with the massage mechanism can be made lightweight and compact, easy to carry, and does not require much storage space. (3) The structure of the massage mechanism is simple, the cost can be reduced, and a chair-chair massager can be provided at a low price. (4) Since the weight of the massage mechanism can be reduced, even if the movable table including the treatment element is moved to the upper part of the backrest, the weight does not cause the chair to fall backward.

Further, in addition to the above effects, the following effects can be further obtained. (5) With the configuration of claim 4, it is possible to cause the treatment element to perform a more complicated treatment operation, and it is possible to further enhance the massage effect.
