BACKGROUND OF THE INVENTION
The present invention relates to a massage machine, and more particularly, to a massage machine that can move up and down in the vertical direction (height direction) of a massage machine body and that can impart various massage actions to the body. It is.
[0002]
[Prior art]
Various types of massage machines have been known in the past, and a representative type is a chair type massage machine. As is well known, this type of conventional massage machine includes a massaging device composed of a kneading tool composed of a pair or two pairs of roller rollers and a drive unit that imparts various swinging motions to the kneading tool. Equipped to be able to move up and down along the backrest surface, by operating the control unit, you can massage to move up and down the massage device part continuously and roll while rolling or squeezing from the neck part to the waist part, In addition, the massage device unit can be stopped at a desired position, and the squeezing wheel can perform a selected squeezing operation such as squeezing, hitting, and acupressure.
[0003]
[Problems to be solved by the invention]
However, the above-described conventional general-purpose massage machine is configured to transmit the rotation of the motor electrically or mechanically to the kneading tool so as to impart various kneading movements to the kneading tool. The generation of noise from the body and the motion part is unavoidable, and the mechanism becomes more complicated with the increase in the types of motion of the greasing tool. Since it depends on elasticity, it has a disadvantage that it is difficult to obtain soft squeeze pressure adjustment by human hands.
[0004]
Recently, for example, as shown in Japanese Patent Application Laid-Open No. 7-124210, an air bag (air cell) is attached to the contact surface of a human body of a chair type massage machine, and the air cell is supplied by exhausting air into the air cell. There has been proposed a massage machine that is inflated and stretched to perform a shiatsu massage while applying an air cushion. Such a massage machine has the advantage that it can be operated very quietly because the massage tool is operated by air pressure, can be operated very quietly, and a soft massage can be obtained.
[0005]
However, in the massage machine, the massager is a finger depressor with a rounded tip, and this acupressure member is a structure in which the acupressure member is fixedly projected on the air cell. Although it is advantageous, like the conventional general-purpose massage machine described above, the massage device part is continuously moved up and down to roll between the neck part and the waist part of the body while rolling or squeezing, In addition, the massage apparatus unit is stopped at a desired position, and the selected squeezing operation such as squeezing, striking, and acupressure cannot be performed, and there is a problem that the variety of squeezing functions is poor.
[0006]
The present invention makes use of the advantages of the above-described air cell and further enhances the characteristics of the conventional general-purpose massage machine, has low noise and flexible squeezing pressure, and provides various massages according to user's desired location. It is made for the purpose of providing the massage machine which can be provided.
[0007]
[Means for Solving the Problems]

Each of the squeezing wheels can be moved back and forth or from side to side by the operation, and the above-mentioned problem can be solved by adjusting the spacing between the squeezing wheels located on the upper side.
[0008]
That is, the massage machine of the present invention is a massage machine in which the massage device part is movable in the vertical direction, and the massage device part is connected to the elevating mechanism in the massage machine and the front side of the base frame. And a pair of left and right squeezing wheels positioned above and below the front surface of the rocking plate. The lower end of the base frame is pivotably supported in a seesaw-like manner by the pivot link and the lower link at both lower positions of the base frame. Two levers on each of the left and right sides of the half and lower half, and a frame member with a plate at the tip between the levers, the plates of the left and right frame members are almost the same From the state where each of the frame members is pivotally supported so as to be pivotable in the opposite direction, and the squeezing wheel is rotatably supported at the tip of the plate of each frame member. A rear air cell that expands and contracts by supplying and discharging air is disposed above and below, and a front air cell that expands and contracts by supplying and discharging air is disposed on the lower surface side of each frame member plate. The left and right frames are configured such that various stagnation movements are imparted to the squeezing wheel by air supply / exhaust control of the rear air cell and / or the front air cell, and further disposed on the upper half side of the swing plate The members are mounted on the swing plate so as to be movable in the left-right direction, respectively, so that the distance between the left and right squeezing wheels on the upper half side can be adjusted.
[0009]
The air cell applied to the present invention has a function of forming a synthetic resin sheet or a leather-like non-breathable flexible sheet in a bellows shape and expanding and contracting in the height direction by supplying and discharging air inside. The effective extension dimension in the height direction is preferably about 80 to 180 mm. Within this extension range, the swinging plate or the seesaw-like swinging of the swinging plate and the longitudinal direction of the frame members The movement of the swinging plate and each frame member is transmitted to each kneading wheel, and the body is massaged.
[0010]
The two rear air cells disposed between the base frame and the swing plate and the four front air cells disposed between the swing plate and each frame member function individually. Thus, it is connected to the air control unit by an air supply / exhaust pipe. The air control unit is equipped with an air pump and a motor for supplying and exhausting these six air cells individually or in plural, a number of solenoid valves, and an air supply / exhaust circuit, and stores a preset program. A solenoid valve is actuated by a microcomputer (microcomputer), and each of the six air cells is operated individually or plurally so that various stagnation motions are transmitted to the squeezing wheel.
[0011]
The squeezing ring is preferably made of an elastic material, and the body can be softly massaged by the elasticity of the squeezing ring itself and the cushioning action of the air cell.
[0012]
The means for moving the left and right frame members disposed on the upper half of the swing plate in the left-right direction on the swing plate is not particularly limited, and the left and right frame members are swung. The left and right frame members are mounted so as to be movable in the left-right direction on the plate, for example, using a right-handed screw shaft on one half and a left-hand screw shaft on the other half. It is good to comprise so that each may be moved to an opposite direction.

[0017]
Two rear air cells 33 and 34 disposed between the base frame 10 and the swing plate 11 and between the swing plate 11 and the frame members 28, 29, 30 and 31. The four front air cells 36, 37, 38, 39 are not shown in the figure, but are connected to the air control unit by air supply / exhaust pipes so as to function independently. The air control unit is equipped with an air pump and a motor for supplying and exhausting these six air cells individually or in plural, a large number of solenoid valves, and an air supply / exhaust circuit. When a desired stagnation operation stored in the microcomputer and displayed on the operation controller 4 is selected, the solenoid valve is actuated by a command from the microcomputer, and each of the six air cells is operated individually or at the same time, and the swing plate 11 and / or the frame members 28, 29, 30, 31 are moved, thereby causing the four squeezing wheels described above to perform a desired squeezing motion.
[0018]
Next, the operation procedure of the above-described massage machine of the present invention will be described. First, the user operates the operation controller 4 to raise or lower the massage device unit 2 to stop the massage device unit 2 at a desired position on the body. After being positioned, when the “Shiatsu” mode is selected from the motion controller 4 and the drive switch is turned on, the air is slowly supplied to and discharged from the rear air cells 33 and 34 to expand and contract. Slowly moves forward and backward to cause the four squeezing wheels 12, 13, 14, and 15 to simultaneously appear and disappear toward the body (see FIGS. 7 and 8), and sometimes the rear air cells 33 and 34 alternately supply and discharge air. 9, the swinging plate 11 is swung in a seesaw shape around the pivoting shaft 35 of the pivoting link 16 and the moving link 19, and the upper and lower squeezing wheels 12, 13 and 14 are moved. 15 Pressing the upper and lower parts of the body alternately Te, cushioning properties of each air cells effectively carry out a pleasant Shiatsu-style massage act.
[0019]
Further, the operation controller 4 is operated to raise the massage device unit 2 so that the two massaging wheels 12 and 13 on the upper side of the massage device unit 2 are stopped at the position of the body, for example, the shoulder, and then the operation controller 4 is turned on, the program is commanded to the air control unit by the microcomputer, and the two front air cells 36 and 37 in the upper half of the swing plate 11 are simultaneously controlled. As the air is supplied and discharged, the two air cells 36 and 37 expand and contract, and the left and right frame members 28 and 29 reciprocate in opposite directions, respectively, as indicated by arrows in FIG. When the squeezing wheels 12 and 13 are moved forward, the squeezing wheel interval is reduced, and when the squeezing wheels 12 and 13 are moved backward, the squeezing wheel interval is repeated. In some cases, air is supplied to and discharged from the rear air cell 33 located on the back side of the upper half of the swing plate 11, and the rear air cell 33 expands when the squeezing wheels 12 and 13 are advanced. An operation of contracting when the wheels 12 and 13 are retracted is added, so that the squeezing wheels 12 and 13 are imparted with a so-called pushing and pulling action, and the shoulder massage is effectively performed in combination with the cushioning property of the air cell.
[0020]
Next, when the “tapping” mode is turned on from the motion controller 4, the program is similarly commanded to the air control unit by the microcomputer, and the upper side between the base frame 10 and the swing plate 11 is instructed. Air is supplied to and discharged from the rear air cell 33 at a high speed, and as shown in FIG. 10, the rear air cell 33 is expanded and contracted, whereby the swing plate 11 is swung back and forth, and the upper squeezing wheel 12, A hitting action indicated by an arrow is given to 13 and a hitting massage is performed. If it is desired to weaken the degree of hitting, when the “weak” mode is turned on from the motion controller 4, the front air cells 36, 37 located on the back side of the squeezing wheels 12, 13 are turned on. The air is supplied and discharged so that the rear air cell 33 expands when the rear air cell 33 contracts and contracts when the rear air cell 33 expands, and the hitting stroke can be reduced to reduce the hitting degree.
[0021]
Further, when a light tapping massage with four kneading wheels is required, if the “tapping kneading” mode is turned on, the back side of the four kneading wheels 12, 13 and 14, 15 as shown in FIG. The front air cells 36, 37 and 38, 39 are alternately expanded and contracted at high speed, and massage is performed as if they were struck with four hands.
[0022]
Similarly, when the “roller” mode is turned on, the elevating mechanism of the massage machine body 1 is operated to move the massage device unit 2 up and down, and the four massaging rings reciprocate along both sides of the spine of the body. Move and perform spinal correction rolling massage. At that time, the strength of the stagnation ring acting on the back can be adjusted by supplying and exhausting the front air cells 36, 37, 38, 39. When this “roller” is selected, the air supply and exhaust pipes of the rear air cells 33 and 34 are communicated according to the program, and the upper and lower squeezing wheels 12, If the internal pressure of one of the upper and lower rear air cells 33, 34 is increased due to fluctuations in the positions of 13, 14 and 15, the air in that air cell flows into the other air cell and the internal pressure of both air cells 33, 34 The swinging plate 11 swings like a seesaw so that the upper and lower squeezing wheels are oscillated to adjust the contact pressure of the squeezing wheel to the body, and the massage device unit 2 is at the highest position. As shown in FIG. 12, the swinging plate 11 can be largely tilted to the front side as shown in FIG. 12, and the swinging plate 11 corrects the tilt as it descends. It is possible to carry out the-ring.
[0023]
When the massage device 2 is stopped at the position where the massage device portion 2 reaches the highest position, or at the position where the massage device portion 2 descends and reaches the waist, and the “itching” mode is turned on, The movement shown in FIG. 4 is given to 14 and 15, and it is possible to give a massage massage mainly on the vicinity of the neck of the body or the waist.
[0024]
Further, in the present invention, the left and right frame members 28 and 29 disposed in the upper half on the front surface side of the swing plate 11 are configured such that the base supporting the frame members 28 and 29 is the base 28A, It is separated by 29A and is slidably mounted on the swing plate 11 so that it can be adjusted to increase or decrease the distance between the upper left and right squeeze wheels 12 and 13 as desired. As a moving means for the bases 28A and 29A for adjusting the distance between the squeezing wheels 12 and 13, in the present embodiment, as shown in FIGS. 13 to 16, it slides on the back side of the bases 28A and 29A. Rules 40 and 41 are provided, and both sides of the sllite rules 40 and 41 are sandwiched by several roller rollers 42 and 42 protruding from the swing plate 11, and the bases 28A and 29A are moved to the left and right along with the slide rules 40 and 41. It can move in the direction.
[0025]
Between the left and right bases 28A and 29A, a screw shaft 45 having a right screw 43 in one half and a left screw 44 in the other half is provided. A nut member 46 is provided at each of the right screw 43 and the left screw 44. 47 and the nut members 46 and 47 and the left and right bases 28A and 29A are connected by links 48, 48 and 49 and 49, respectively, and the screw shaft 45 is controlled to rotate forward or backward by the motor 50. The nut members 46 and 47 are moved toward and away from each other to change the expansion angles of the links 48, 48 and 49, 49, thereby moving the left and right bases 28 A and 29 A in opposite directions to approach the screw shaft 45. The distance W between the left and right squeezing wheels 12 and 13 can be adjusted by moving them away from each other.
[0026]
Therefore, the massage device 2 is stopped at the position where the massage device portion 2 reaches the highest position or the position where the massage device portion 2 descends and reaches the waist, and the “itching” mode is turned on. Alternatively, when the massage shown in FIG. 4 is given to 14 and 15 and massage massage is focused on the vicinity of the neck or waist of the body, the “expansion” or “narrow” mode of the massage ring interval is turned on and the motor 50 is turned on. When the rotation direction is controlled, the left and right frame members 28 and 29 are moved together with the left and right bases 28A and 29A, the interval between the squeezing wheels 12 and 13 is changed, and the squeezing wheels 12 and 13 are set at a desired position of the user. A more comfortable and effective massage can be performed.
[0027]
In addition, in the said embodiment, although this invention is demonstrated about the chair type massage machine, of course, the said structure of this invention is applicable also to a bed type massage machine.
