Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a footrest and a foot massage machine.

[0002]

2. Description of the Related Art Some chair-type massage machines have a footrest at the front of a chair body, and some have a built-in function to enable foot massage to the footrest. As a massage function provided in this type of footrest, a massage function such as a vibration function or a function of causing a foot to perform fir or flap by expansion and contraction caused by supply / exhaust of air to / from an air cell (Japanese Patent Application Laid-Open No. H8-8)
No. 9540) is dominant.

[0003] A flat type (referred to as a floor-standing type) is known as a massage machine which can massage not only feet but also any part of the body as desired by the user. In this type of massage machine, a rotary shaft having a cylindrical or disk-shaped rotor in a skewered shape is rotatably built therein, and when the rotary shaft rotates, fir, hit, finger pressure, There is one in which rubbing or the like is performed (see Japanese Utility Model Publication No. 2-35352).

[0004]

In order to meet various needs of the user in the footrest,
In some cases, he wanted to adopt a novel massage action other than the one using a vibration or an air cell. Further, in the case of using an air cell, there has been a demand for reducing the sound of supply / exhaust if possible, and a demand for replacing the structure for supply / exhaust with a small and simple structure. On the other hand, when using a flat (floor type) massage machine for foot massage, it is difficult to determine the massage position for the foot each time, and the foot may move during the massage. In order to prevent this, the user has to put his / her effort on the foot, and there is a problem that the massage effect is weakened.

The present invention has been made in view of the above circumstances, and as a footrest used in connection with a chair body, a novel massage operation can be obtained, the operation sound is quiet, the structure is reduced in size and the structure is simple. It is an object of the present invention to provide a footrest that can be converted into a footrest. The present invention also provides
As a foot massager that can be used separately and independently from the chair body, the massage position for the foot can be easily and reliably determined, and the massage effect is prevented by preventing the foot from moving during the massage. An object of the present invention is to provide a foot massage machine that can be sufficiently exercised.

[0006]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, in the footrest according to the present invention, the upper surface is provided as a footrest surface provided at the front part of the chair main body, and the axis can be driven to rotate in the left-right direction at the lower part of the footrest surface. It has a rotating shaft provided and a rotor provided in a skewered manner in a state inclined to the rotating shaft. Therefore, by rotating the rotating shaft, the rotor rotates while swinging its outer peripheral part to the left and right. In this state, if a foot is placed on the footrest surface, the outer peripheral part of the rotor that moves left and right moves the foot. Massage will be performed. Such a massage operation is novel as a massage operation obtained by a footrest.

Of course, since the air cell is not operated, the operation sound is quiet and the structure can be reduced in size and simplified. The rotors may be provided in pairs for each foot at a mutual interval at which the feet can be pinched, and in this way, it is possible to obtain a massage operation such as grabbing and firing the feet. it can. A pair of opposing standing surfaces may be provided for both feet so that a foot recess is formed for each foot with respect to the foot rest surface. In this case, each rotor may be arranged on each back side of the opposing rising surface.

[0008] By doing so, the massage position for the foot can be easily and reliably determined.
Further, since the foot does not move during the massage, the massage effect can be sufficiently exhibited. In addition, each rotor can be positioned irrespective of the opposing rising surface, and therefore, the number of rotors provided is not particularly limited. On the other hand, in the foot massage machine according to the present invention, an apparatus main body having a foot resting surface formed on an upper surface, a rotation shaft provided rotatably in the apparatus main body with an axial center directed to the left and right directions, and A rotor provided in a skewered manner in a state of being inclined to the shaft, wherein the foot placed on the foot resting surface can be massaged at the outer peripheral portion of the rotor that moves left and right when the rotation shaft rotates, and the device A pair of opposing standing surfaces for forming a foot recess for each foot are provided for both feet on the foot rest surface of the main body.

That is, the present invention differs from the above-described footrest of the present invention in that the main body of the apparatus is not limited to be provided at the front of the chair main body. With such a configuration,
The massage position can be easily and reliably determined for the foot. Further, since the foot does not move during the massage, the massage effect can be sufficiently exhibited. Also in this foot massage machine, the rotor may be arranged on each back side of the opposing standing surface.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a first embodiment of a footrest 1 according to the present invention. The footrest 1 is provided at the front of the chair body 3 in the chair-type massage machine 2 or the like, and has a connection shaft 4 with the chair body 3.
Is swingable in the vertical direction with the fulcrum as a fulcrum, and the swing angle can be arbitrarily set and fixed. In the use state in which the footrest 1 is flipped up, the upper surface facing upward is the footrest surface 5.

The above-mentioned chair body 3 does not necessarily need to be the massage machine 2 but may be a chair having no massage function. Also, regarding that the footrest 1 can swing up and down with respect to the chair body 3,
The present invention is not limited to this, and it suffices that at least a state of upward jump can be obtained. A pair of opposed rising surfaces 7 for forming a foot recess 6 for each foot is formed on the foot rest surface 5.
Are provided for both feet, and in appearance, two groove-shaped recesses are provided to pass through in the front-rear direction while being parallel to each other.

That is, a side wall 10 is provided on each of the left and right outer sides with respect to the both foot recesses 6, and a central distribution table 11 is provided between the two foot recesses 6. The opposite upright surface 7 is formed as both left and right side surfaces of the table 11. The side wall 10 and the center sorting table 11 are formed into a predetermined shape by a solid or hollow core material 12 made of foamed resin, a resin molded product, wood, or the like. It is covered with an elastic resin-based sheet material or the like (not shown), so that the skin feels good. In particular, the opposing standing surface 7 is made of a material having a material with abundant elasticity, or a material having a flexure or bellows structure for allowing the material to be expanded and contracted (a material having an extra length for cutting and sewing the fabric parts). 13 and so on.

In the lower portion of the foot rest surface 5, the side wall 1
An apparatus main body 18 is formed such that a storage space 17 for machinery is formed above and below the base plate 16 by, for example, attaching the base plate 16 between lower ends of the zeros. In the storage space 17 of the apparatus main body 18, a rotating shaft 21 spanned between the left and right brackets 19 with the axis centered in the left-right direction, and a plurality of rotors provided in a skewered manner around the rotating shaft 21. 22 are provided. The rotating shaft 21 has a structure in which rotational driving from a motor 24 is transmitted through an interlocking mechanism 23 such as a worm provided at a central portion in the longitudinal direction. The interlocking mechanism 23 and the motor 24
A speed reducer, a torque limiter, and the like (both not shown) are provided integrally with each other or separately connected to each other.

There are a total of four rotors 22, of which two are located on the right and two on the left are assigned to each foot of the user. Are arranged so as to form a pair with a mutual interval capable of sandwiching them. Each rotor 22 is formed in the shape of a disk having a boss 25 for insertion into the rotating shaft 21 at the center, and approximately half the area above the rotating shaft 21 is provided on each back side of the opposing standing surface 7. Are arranged. Each of the rotors 22 is provided so as to be inclined with respect to the rotation shaft 21 and to be unable to rotate relative to the rotation shaft 21. The inclination of each of the rotors 22 is set to a relative opposite direction in all adjacent positional relationships.

Thus, when the two rotors 22 assigned to one leg are viewed from a certain point around them while rotating the rotating shaft 21, the outer peripheral portions of the two rotors 22 are formed in a C-shape with each other. This results in a state in which the shape changes alternately. That is, the outer peripheral portions of these rotors 22 move left and right in a mutually approaching / separating manner. Therefore, in this footrest 1, if the rotary shaft 21 is rotated in a state where the left and right feet F are separately fitted in the respective foot recesses 6 of the footrest surface 5, the outer peripheral portions of the respective rotors 22 are provided as described above. Repeats left and right movements, thereby holding or loosening each foot F to massage (grasp fir)
Is what you do.

The overall positioning of each rotor 22 in the left-right direction with respect to the rotating shaft 21, the mutual spacing (see the arrow X direction in FIG. 3), the mutual phase angle, etc. should be adjustable. It is suitable. Above all, when adjusting the mutual interval between the two rotors 22 that hold the foot F in a mutual relationship, a structure that can be performed by a simple operation from the outside of the apparatus main body 18 is adopted. However, it is preferable in that it can be adapted to the body type (thickness of the foot F) for each user.

As a mechanism for realizing this, although not shown, for example, a screw screw is engraved on the rotating shaft 21 and a boss portion 25 of one of the rotors 22 can be screwed thereto. The structure may be such that a nut function is provided, these are screwed together, and the rotation shaft 21 and the rotor 22 are relatively rotated as necessary. It is also recommended that the rotor 22 be movable in the front-rear direction with respect to the apparatus main body 18 (see the arrow Y direction in FIG. 3).
If such a function is provided, the user's height difference (foot F
Not only can the position of the massage position be adjusted with respect to the length of the foot F, but also the selection of the desired massage position of the foot F (massage of a desired position from the thigh to the ankle) becomes possible.

As a mechanism for realizing this, although not shown, for example, a structure in which the left and right brackets 19 supporting the rotating shaft 21 are moved along ball screws provided in the front-rear direction is appropriate. . It should be noted that if such forward and backward movement of the rotor 22 can be performed simultaneously and continuously and repeatedly while the rotor 22 is rotating, massage of the entire foot from the thigh to the ankle can be automatically performed, which is more preferable. is there. Here, the chair body 3 of the chair-type massage machine 2 to which the footrest 1 according to the present invention is attached will be briefly described with reference to the drawings.

The chair body 3 has a backrest portion 30, a seat surface portion 31, and an armrest 32.
Numeral 0 is connected to the seat portion 31 so as to be reclined by electric power, fluid pressure drive, or manual operation. When the backrest 30 is reclined, the vertical swing of the footrest 1 may be interlocked, or the back and forth movement of the seat 31 may be interlocked. It is also possible to provide the footrest 1 so as to be able to move back and forth with respect to the seat surface portion 31 in a state where the footrest 1 is flipped up.

Inside the backrest 30, an upper movable table 35 which can be moved up and down by a vertical screw feed mechanism 34,
A lower fixed base 36 fixed below is provided. An air cell 37 for massaging the neck is provided in the upper movable table 35 in a state where the operator 38 can be operated, and an air cell 39 for massaging the back is provided in a state in which the operator 40 can be operated. Have been.
The lower fixed base 36 is provided with an air cell 41 capable of massaging the waist so that the operator 42 can operate.

On the other hand, the seat portion 31 is provided with an air cell 43 for massaging the buttocks and an air cell 44 for massaging the back of the thigh. Each of the air cells 37, 39, 41, 43, and 44 has a seat surface 31.
And an air supply / discharge circuit, a control unit, and the like (both not shown) housed and installed in a space below the apparatus. Therefore, each air cell 37, 3
Due to the expansion and contraction of 9, 41, 43 and 44, each operator 3
With or without the intervention of 8, 40, 42, each part of the body is appropriately massaged by fir, beating, acupressure, rubbing and the like.

Needless to say, these massages
The massage operation may be performed simultaneously with the footrest 1 or may be performed alone. In this case, the footrest 1 may be used not only in a state of being flipped up, but also in a state of being dropped down or in the middle thereof. FIGS. 4 to 9 show the configuration of each part that can be employed in the footrest 1 according to the present invention. That is, FIG. 4 shows an example in which a plurality of rotors 22 (two rows in the illustrated example, but more than two rows) may be provided along the longitudinal direction of each foot recess 6 of the foot placement surface 5. By doing in this way, massage at a plurality of places at a time becomes possible.

It should be noted that, depending on the massage position, the rotor 2
2 may have different diameters or different inclination angles with respect to the rotating shaft 21. FIG. 5 is an example in which a combination of a timing belt 50 and a timing pulley 51 is used as the interlocking mechanism 23 for transmitting the rotation drive from the motor 24 to the rotation shaft 21. In addition, a gear mechanism (not shown) may be used. FIG. 6 shows a structure in which one of the rotors 22 arranged in the center can be shared by the left and right feet F (the two rotors 22 arranged in the center shown in FIG. Same as you did).

FIG. 7 shows the outer periphery of each rotor 22.
This is an example in which a plurality of stimulation protrusions 53 projecting in the axial direction are provided at a plurality of locations in the circumferential direction. FIG.
This is an example in which only two rotors 22 are provided for one rotating shaft 21, and each one rotor 22 performs a massage operation on each foot F. A stopper member 54 for preventing the foot F from escaping is provided at a central position between the two rotors 22. In this example, the rotors 22 may be positioned closer to the center, and the stopper members 54 may be positioned so as to be positioned on both left and right outer sides.

FIG. 9 shows an example in which the rotor 22 is positioned just below the foot F. Needless to say, in this example, since the rotor 22 does not sandwich the foot F, only two rotors 22 are provided for one rotation shaft 21. FIG. 10 shows an embodiment of the foot massage machine 60 according to the present invention. The foot massage machine 60 includes a device main body 63 having a foot rest surface 62 formed on an upper surface thereof, and a rotary shaft 64 provided so as to be rotatable inside the device main body 63 with its axis being directed in the left-right direction.
And a rotor 65 provided in a skewered manner in a state inclined with respect to the rotation shaft 64.

On the foot mounting surface 62 of the apparatus main body 63,
A pair of opposing standing surfaces 67 for forming a foot recess 66 for each foot is provided for both feet. The foot placed on the foot rest surface 62 can be massaged at the outer peripheral portion of the rotor 65 that moves left and right when the rotation shaft 64 rotates. That is, this foot massage machine 60
It can be said that the footrest 1 according to the present invention can be used independently of the chair body 3. Therefore, this foot massage machine 60 can also adopt the configurations of the embodiments described with reference to FIGS. 1 to 3 and the modifications described with reference to FIGS. 4 to 9.

This foot massage machine 60 can be used alone, so it can be used not only for foot massage,
It can also be used for massage of arms and the like. The present invention
The present invention is not limited to the above embodiments, and various modifications can be made to the detailed structure. For example, the footrest surface 5 of the footrest 1 is formed of a stretchable fabric such as rubber fabric so as to be flat when not in use, and the opposing standing surface 7 (foot recess 6 ) May be formed.

[0028]

As is apparent from the above description, the footrest according to the present invention is capable of massaging the foot placed on the footrest surface by the rotor rotating while swinging the outer peripheral portion left and right. Such a massage operation is novel as a massage operation obtained by a footrest. Unlike an air cell, the operation sound is quiet, and the structure can be reduced in size and simplified. By widening the interval between the rotors so that the feet can be pinched, it is possible to obtain a massage operation in which the feet are grasped and fir. In addition, if a foot recess is formed in the foot rest surface, the foot can be fixed, and an efficient massage can be obtained.

On the other hand, in the foot massage machine according to the present invention,
It can be used independently of the chair body, and has advantages such as simplification of the structure and expansion of the degree of freedom of use.
