BACKGROUND OF THE INVENTION
The present invention relates to a chair type massage machine provided with a shoulder massage device for massaging the shoulder of a human body.
[0002]
[Prior art]
For example, in a chair type massage machine, a massage unit that massages the shoulders of the human body with an air bag (massage element) that expands and contracts by air supply and exhaust is provided on the backrest so that the position can be adjusted vertically There is. In addition, a massage unit, commonly called a kneading ball, which has a roller (massage element) that is driven by the power of an electric motor, is movably provided on the backrest, etc., and the shoulder position of the human body is detected using the massage element. Also known are chair-type and bed-type massage machines that control the movement of the massage unit based on this detection and massage the upper body of the human body. In these massage machines, the massage element can be adjusted to the shoulder position of the human body by moving and adjusting the massage unit along the body axis direction of the human body.
[0003]
In addition to moving the entire massage unit in the body axis direction of the human body in this way, moving the entire massage unit in the other direction requires a large-scale mechanism and is extremely difficult to realize. It is considered. Therefore, a massage machine that can move the entire massage unit in the thickness direction of the human body supported by the backrest and adjust the position of the massage element has not yet been provided.
[0004]
The shoulders of the human body not only differ in height depending on individual differences, but also have different shapes and thicknesses, and the upper body may bend in the thickness direction, etc. Naturally, there are individual differences in the position of the vase that is effective for shoulder massage.
[0005]
However, since the conventional massage machine cannot adjust the position of moving the massage element in the thickness direction of the human body as described above, it can be moved to a desired position such as the position of a vase such as the shoulders of various users or a favorite position. It is difficult to massage with a massage child. Therefore, there is a case where the massage desired by the user cannot be performed, and an improvement thereof is desired.
[0006]
In addition, when massaging the back of the shoulder or neck of a seated person in a chair with a massage force, the head of the human body tends to slide backwards as the shoulder is pushed forward. It is desirable to provide a pillow that supports the human head. However, it is also desirable to prevent this from happening because it can get in the way if the pillow is always protruding.
[0007]
[Problems to be solved by the invention]
The problem to be solved by the present invention is to obtain a chair-type massage machine that can massage a massage element in accordance with a desired position of a human body shoulder and is easy to use.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a chair body having a backrest, a shoulder massage device that is provided on the backrest and massages a shoulder portion or a neck shoulder portion of a seated person, and this shoulder massage device. A massage device comprising a drive device for performing massage operation by driving the shoulder massage device, wherein the shoulder massage device is attached to the rotation plate and the rotation plate so that the shoulder of the seated person is obliquely downward and forward A shoulder massager having a massager that is pressed and massaged, and the shoulder massager by changing the position of the shoulder massager so that the massager is disposed at a desired position in the thickness direction of the shoulder If the position adjusting body is arranged so as to cover the shoulder portion of the human body from behind obliquely from above, and the rotating plate is urged so that the back surface of the rotating plate is pressed against the position adjusting body Wherein the positioning member is characterized in that it also serves as a pillow element that functions as a pillow for supporting the head of the seated person protrudes above the shoulder massage unit.

[0016]
As shown in FIGS. 1 and 2, a shoulder massage device 15 that requires position adjustment is attached to the upper portion of the backrest 4. A pair of lower back massage devices 16 is attached to the lower portion of the backrest 4, and a back massager, for example, an air bag 17, is disposed between the devices 15, 16 at the center in the width direction of the backrest 4. ing.
[0017]
A shoulder massage device 15 for massaging the shoulder or neck of a human body seated on the chair body 2 will be described with reference to FIGS. The massage device 15 includes a massage unit 22, a height position adjusting body, for example, one or more, more specifically, two airbags 23, and a return spring 24 in a device frame 21.
[0018]
The device frame 21 is fixed to the upper part of the back frame 4a. The device frame 21 has groove-like rails 25 extending in the longitudinal direction of the backrest 4 in other words, in other words, in the body axis direction of the seated person. The pair of rails 25 are provided such that openings extending in the longitudinal direction face each other.
[0019]
The massage unit 22 includes a unit base 26, a shoulder massager 27, and a position adjuster 28 for changing the position of the massager 27 in the thickness direction of the seated person. The unit base 26 has a front wall 26a and an end wall 26b that is located on the distal end side of the backrest 4 and that is connected to the front wall 26a at a substantially right angle. The front wall 26 a is formed of a flat plate having a width slightly shorter than the distance between the pair of rails 25. A plurality of rollers 29 are rotatably attached to the left and right sides of the unit base 26, respectively.
[0020]
As shown in FIGS. 3 and 7, the unit base 26 is combined with the apparatus frame 21 by inserting the roller 29 into the rail 25. Therefore, the unit base 26 of the massage unit 22 is provided so as to be movable along the rail 25 in the body axis direction of the seated person. As shown in FIGS. 4 to 6, the end wall 26 b extends across the rail 25 in the combined state.
[0021]
The shoulder massager 27 is disposed in front of the front wall 26a, and is a masseur support plate, for example, a single rotary plate 31, and a pair of shoulders attached to this surface in the width direction of the chair body 2. For example, an air bag 32 is provided. As shown in FIG. 3, a mounting portion 33 is integrally projected on a part of the outer periphery of the airbag 32, and air is attached by a mounting tool 34 such as a screw that is screwed into the rotating plate 31 through the mounting portion 33. The bag 32 is fixed in a cantilevered state. In this case, the pair of airbags 32 are attached to the rotating plate 31 with their attachment portions 33 approaching each other.
[0022]
The inflated and contracted portions of the two airbags 32 that inflate and contract by air supply and exhaust are circular in plan view, and contracted so as to be thin in the exhausted state (represented by the right side portion in FIG. 7) and supplied. Is formed so as to expand into a substantially hemispherical shape (represented by the left portion of FIG. 7). In addition, the top portion 32a of the expansion / contraction portion is eccentric from the center of the expansion / contraction portion toward the attachment portion 33, whereby the expansion / contraction portion expands from the contracted state while gradually moving the top portion 32a to the attachment portion 33. It is like that. The movement trajectory of the top 32a in this case is indicated by an arrow on the left side of FIG. Accordingly, when the airbags 32 are inflated in synchronism, their top portions 32a are brought closer to each other.
[0023]
The rotating plate 31 functions as a wall that prevents the airbag 32 from inflating toward the back. One side portion, for example, the lower side portion of the rotating plate 31 is attached to the front wall 26 a via a pair of hinges 35. Therefore, the shoulder massager 27 is provided so as to be rotatable in the vertical direction with the hinge shaft of the hinges 35 as a fulcrum. A coiled spring 35 a is attached to the hinge 35. By this spring 35a, the rotating plate 31 is urged in the direction in which the free end side is brought close to the front wall 26a.
[0024]
The position adjusting body 28 is formed of an air bag that expands and contracts by supply and exhaust, for example. As shown in FIGS. 4 to 6, the position adjuster 28 is provided with its lower part positioned between the front wall 26 a and the rotating plate 31 and fixed to the front wall 26 a. The upper part of the position adjustment body 28 protrudes above the shoulder massage part 27. The upper portion of the position adjusting body 28 is used as a pillow element 28a. Even when the position adjusting body 28 made of an air bag is contracted as shown in FIG. 4, the position adjusting body 28 is adjusted as shown in FIG. Even when the body 28 is inflated, the state where it protrudes above the shoulder massager 27 is maintained.
[0025]
The rear surface of the rotating plate 31 is pressed against the position adjusting body 28 arranged in this way by the biasing force of the spring 35a. The front wall 26a functions as a wall that prevents the position adjusting body 28 from expanding toward the back. Therefore, the shoulder massager 27 is tilted forward with the hinge 35 as a fulcrum as the position adjustment body 28 is expanded, and is pushed back by the force of the spring 35a so as to stand up as the position adjustment body 28 contracts. It is.
[0026]
The airbags 23 are overlapped with each other and sandwiched between the end wall 21 a of the apparatus frame 21 and the end wall 26 b of the unit base 26. The return spring 24 is provided with both ends thereof connected to the end walls 21a and 26b, respectively, and always urges the unit base 26 toward the end wall 21a. Therefore, as the air bag 23 expands, the massage unit 22 is pushed and moved along the rail 25 against the biasing force of the return spring 24, and as the air bag 23 contracts, massage is performed with the biasing force of the return spring 24. Unit 22 is pulled.
[0027]
The configuration of the pair of lower back massage devices 16 is the same as the configuration of the shoulder massage portion 27. That is, as shown in FIG. 2 (A), the waist massage device 16 is attached to the front surface of the back base cushion 4b in a width direction of the chair body 2 and the support plate 41 fixed with an adhesive or the like. A pair of lumbar massagers, for example, an air bag 42 is provided. The structure of the air bag 42 is the same as that of the shoulder air bag 32, and the air bag 42 is attached by an attaching tool 44 such as a screw that is screwed into the support plate 41 through a mounting portion 43 protruding from a part of the outer periphery thereof. The bag 42 is fixed in a cantilevered state. In this case, the pair of airbags 42 are attached to the support plate 41 with their attachment portions 43 approaching each other.
[0028]
The back portion airbag 17 is formed in a vertically long shape, and only a fixed end portion (upper end portion in FIG. 2) having the air supply / exhaust port is fixed to the front surface of the back portion base cushion 4b with an adhesive or the like. The other end of the airbag 17 is simply a free end overlapping the front of the back base cushion 4b. Therefore, the air bag 17 that is inflated and contracted by air supply and exhaust is inflated so that the free end portion is close to the fixed end portion, and an upward force is applied to the seated person during the inflation.
[0029]
The back cushion 4c and the back cover 4d have a degree of freedom that can be easily deformed following the up and down movement and forward tilting movement of the massage unit 22 and the inflating movement of the airbags 42 and 17.
[0030]
A driving device 50 is disposed below the seat portion 3. As shown in FIG. 9, this device 50 includes an air pump 52 that performs a pump operation by moving a diaphragm by electromagnetic drive, and an air such as a rotary valve connected to an outlet of the pump 52 via an air tube 53. Distributing device 54, electromagnetic valve 55 connected to first tube 53a branched from air tube 53, electromagnetic valve 56 connected to second tube 53b branched from air tube 53, and control device 51 I have.
[0031]
One end of an air tube 57 is connected to the first distribution port of the air distribution device 54, and the other end of the tube 57 is connected to one end of a tridentate air supply / exhaust port body 58 shown in FIG. Has been. The other two ends of the air supply / exhaust port body 58 are communicated with the waist airbag 42, respectively. The second distribution port of the air distribution device 54 communicates with the back airbag 17 via the air tube 59. One end of an air tube 60 is connected to a third distribution port of the air distribution device 54, and the other end of the tube 60 is connected to one end of a tridental air supply / exhaust port body 61 shown in FIG. . The other two ends of the air supply / exhaust port body 61 communicate with the shoulder airbag 32.
[0032]
The rotary valve constituting the air distributor 54 has an exhaust port (not shown), and when the air supply to one distribution port is selected, the other distribution port communicates with the exhaust port. Each distribution port is selected in turn as the rotor (not shown) is rotated by the step motor.
[0033]
Two air bags 23 for height adjustment are communicated with the electromagnetic valve 55 via the air tube 62, and the position adjuster 28 is communicated with the electromagnetic valve 56 via the air tube 63. Each of these solenoid valves 55 and 56 has an exhaust port, and an air supply position, a closing position, and an exhaust position can be selected.
[0034]
The electromagnetic valve 55 allows air supply to the air bag 23 at the intake position, closes the flow path at the closed position to maintain the inflated state of the air bag 23, and discharges air that has flowed out of the air bag 23 at the exhaust position. It can be discharged to the outside. Similarly, the solenoid valve 56 allows supply of air to the position adjustment body 28 at the intake position, closes the flow path at the closed position and maintains the expanded state of the position adjustment body 28, and flows out of the position adjustment body 28 at the exhaust position. The discharged air can be discharged to the outside through the exhaust port. Thus, the electromagnetic valves 55 and 56 are used as the inflation holding elements of the airbag 23 and the position adjusting body 28 corresponding thereto, and therefore the position adjusting body 28 and the electromagnetic valve 56 are airbags in the thickness direction of the seated person. The position adjusting means for changing the position 32 is configured.
[0035]
The control device 51 controls the air pump 52, the air distribution device 54, and the electromagnetic valves 55 and 56, and is formed of a microcomputer or the like. The controller 51 is connected to an operation unit operated by a seated person, for example, a remote controller 71, and a driving command is given by the controller 71.
[0036]
As shown in FIG. 8, the remote controller 71 includes various operation buttons, for example, angle adjustment buttons 72a and 72b for changing the angle of the shoulder massager 27 of the massage unit 22 with respect to the human shoulder, and the shoulder and back. Point button 73 for selecting either the massage position of the head or the waist, a course button 74 for performing the course operation, and a pulse button 75 for supplying air with pulsation to the airbag to be inflated and inflated, A strength button 76 for changing the strength of the massage by changing the degree of inflation of the airbag, height adjustment buttons 77a and 77b for changing the height position of the shoulder massager 27 relative to the human shoulder, and all A stop button 78 and the like for ending the operation are provided.
[0037]
The point button 73 that is reset when the stop button 78 is pressed first specifies the shoulder, specifies the back by the first press, specifies the waist by the second press, and again by the third press. The designation of the shoulder is repeated until it is reset. In addition, when a predetermined course driving is performed by pressing the course button 74, a massage operation is performed in which a shoulder portion is designated a plurality of times, a back portion is designated, and a waist portion is finally designated a predetermined number of times. It is.
[0038]
Thus, when the point button 73 or the course button 74 is operated, the massage operation for starting the massage operation from the neck shoulder portion of the human body by the shoulder massage device 15 can be performed. This is because the massaging machine 1 can adjust the position of the airbag 32 two-dimensionally by adjusting the height position of the neck shoulder and the massage point at the neck shoulder portion to the thickness direction position of the human body, as will be described later. Taking advantage of the features of this two-dimensional adjustment, massage is started from the two-dimensional adjustment state.
[0039]
Further, one or more buttons among various operation buttons provided in the remote controller 71, for example, the stop button 78, are controlled differently depending on whether the button is kept pressed for a certain period of time or less than a certain period. Is input to the control device 51. In this case, the control command when the operation button is kept pressed for a predetermined time or more may be added to the control command when the operation button is pressed for less than a certain time, and no massage operation is performed. Even when the operation button is kept pressed for a certain period of time, a preset control command may be input to the control device 51.
[0040]
By adopting the remote controller 71, for example, when the stop button 78 is pressed to wait for the next use, if the duration of the stop button 78 is less than a predetermined time, the operation of all processes is terminated. Although the control command to be given can be given to the control device 51, when the pressing duration of the stop button 78 is longer than a certain time, the entire process is ended after the operation of returning the shoulder massage device 15 to the initial state. A control command can be given to the control device 51.
[0041]
Note that the stop button 78 is normally used when the operation is forcibly terminated in the course of driving, when a predetermined course operation is completed, or when the seated person himself / herself arbitrarily specifies a massage order, a point massage operation, etc. As described above, the pressing operation is performed after the operation mode designated arbitrarily or automatically is completed. In the present embodiment, the initial state of the shoulder massage device 15 means that the airbags 23, 28, and 32 of the device 15 are contracted to return the shoulder massage device 15 to the state shown in FIG. In this state, the shoulder massager 27 of the shoulder massager 15 is held in a stowed position in a standing position so as not to disturb the seated person.
[0042]
As represented by the stop button 78 described above, giving a plurality of control designations to the control device 51 according to the length of pressing time of one operation button includes the angle adjustment buttons 72a and 72b and the point button 73 for massaging mode designation. It can also be applied to other operation buttons such as the course button 74. In this way, in the remote controller 71 having a function capable of giving a plurality of control commands with one operation button, the number of operation buttons included in the remote controller 71 can be reduced, so that the cost of the mote controller 71 can be reduced. it can.
[0043]
When using the massage machine 1 configured as described above, the seated person first adjusts the massage unit 22 to the human shoulder. This adjustment includes a height direction adjustment in which the massage unit 22 is moved in a direction in which the massage unit 22 is moved toward and away from the human shoulder, and a thickness direction adjustment in which the shoulder massage portion 27 is rotated to move in the thickness direction of the human shoulder. It is done with.
[0044]
The height direction adjustment is performed by adjusting the height adjustment buttons 77a and 77b of the remote controller 71. While the pressing operation of the height adjustment button 77a for instructing the direction in which the shoulder massage unit 22 approaches the human body shoulder is continued, the operation of the air pump 52 is continued and the electromagnetic valve 55 is in the air supply position. Therefore, the air supply to the height adjusting air bag 23 is continued, and the air supply is stopped by releasing the pressing operation of the height adjusting button 77a. At the same time, the operation of the air pump 52 is stopped, the electromagnetic valve 55 maintains the closed position, and the airbag 23 is held in an inflated state.
[0045]
Further, while the operation of pressing the height adjustment button 77b for instructing the direction in which the shoulder massage unit 22 moves away from the human shoulder continues, the operation of the air pump 52 is stopped and the solenoid valve 55 is exhausted. Since the position is reached, the air in the height adjusting airbag 23 is exhausted, and the exhaust is stopped by releasing the pressing operation of the height adjusting button 77b. At the same time, the massage unit 22 is pulled up by the urging force of the return spring 24 according to the amount of contraction of the airbag 23.
[0046]
Therefore, by operating at least one of the height adjustment buttons 77a and 77b and moving the massage unit 22 in the direction of contacting / separating the human body shoulder, based on the touch of the airbag 32 against the human body shoulder, etc. The massage unit 22 can be arranged at a height position desired by the seated person. FIG. 6 illustrates a state where the airbag 23 is inflated.
[0047]
In this state, the thickness direction adjustment is performed next, and this adjustment is performed by operating the angle adjustment buttons 72a and 72b of the remote controller. While the pressing operation of the angle adjustment button 72a is continued, the operation of the air pump 52 is continued, and the solenoid valve 56 maintains the air supply position, so that the air supply to the airbag forming the position adjustment body 28 is performed. The air supply is stopped by releasing the pressing operation of the angle adjustment button 72a. At the same time, the operation of the air pump 52 is stopped, the electromagnetic valve 56 maintains the closed position, and the position adjusting body 28 is held in the expanded state.
[0048]
Further, while the operation of pressing the angle adjustment button 72b is continued, the operation of the air pump 52 is stopped and the solenoid valve 56 is in the exhaust position, so that the air in the position adjusting body 28 for adjusting the thickness direction is used. The exhaust is stopped by releasing the pressing operation of the angle adjustment button 72b. The electromagnetic valve 56 maintains the closed position, and the position adjusting body 28 is held in the expanded state.
[0049]
Therefore, by operating at least one of the angle adjustment buttons 72a and 72b and moving the airbag 32 of the shoulder massager 27 steplessly in the thickness direction of the backrest 4, in other words, in the thickness direction of the human body, The air bag 32 can be disposed at an arbitrary position in the thickness direction desired by the seated person based on the touch of the top 32a of the bag 32. As described above, due to the expansion of the position adjusting body 28, the shoulder massage part 27 is rotated so as to fall forward with the hinge 35 as a fulcrum, and is arranged so as to cover the human body shoulder part obliquely from above. This is illustrated in FIG.
[0050]
Both of the above adjustment states are maintained when the solenoid valves 55 and 56 are in the closed position. As the final stage of this adjustment, if the adjustment buttons 72a and 72b are not operated for a predetermined time after the above operation of the angle adjustment buttons 72a and 72b , the operation of the air pump 52 is started and the air distribution device 54 is started. Simultaneous supply / exhaust to the pair of airbags 32 is repeated one or more times, for example, several times. As a result, the pair of airbags 32 are inflated to impart a massage force to the shoulders of the human body, so that it is possible to experience whether or not the acupressure point by the top portion 32a of the airbag 32 is at a desired position depending on the two adjustment states. . If necessary based on this feeling, the above adjustment operation may be repeated to make adjustments so that the desired finger pressure is appropriately applied to the human shoulder.
[0051]
By the above procedure, the top portion 32a of the airbag 32 can be matched to the massage point of the human shoulder that varies depending on the thickness and shape of the seated person's shoulder and the way the upper body bends. After this adjustment, various massages designated by the remote controller 71 can be performed.
[0052]
When the shoulder massage part 27 is operated by this massage and when the shoulder massage part 27 is operated at the final stage of the adjustment, as described above, the shoulder massage part 27 is obliquely applied to the human shoulder part from the upper rear side. Since it is performed in the state arrange | positioned so that it may cover, the massage direction of the airbag 32 differs from pushing a human body to the thickness direction front side.
[0053]
Specifically, a massage is performed from diagonally above and below the shoulder of the human body toward diagonally downward and forward, and as representatively shown in the inflated state of the airbag 32 on the left side in FIG. It is possible to apply pressure to the shoulders of the human body while moving the top portions 32a of the pair of airbags 32 from both sides toward the root portions of the neck portions. Therefore, it is possible to satisfactorily massage the human neck shoulder.
[0054]
And in this massage to the shoulder of the human body, the head of the seated person can be drowned on the upper part of the position adjusting body 28 made of an air bag protruding above the shoulder massage part 27, that is, the pillow element 28a. it can. Therefore, the pillow element 28a prevents the head of the human body from sliding backwards even though the shoulder is pushed forward as a massage force is applied to the neck shoulder of the seated person from the back side. it can. In this way, the neck shoulder portion can be massaged while suppressing the human head from sliding off, so it is easy to use. In addition, since the pillow element 28a is also used as the position adjusting body 28, the number of parts is small and the configuration is simple.
[0055]
Moreover, in the massage machine 1 having the above-described configuration, the airbag 23 is used as an element for moving the massage unit 22 in the height direction, and the element for rotating the shoulder massage unit 22 is also a position formed of an airbag. Since the adjusting body 28 is used, each air bag 17, 32, 42 incorporated in the chair body 2 can be driven by the common driving device 50.
[0056]
Moreover, the massage machine 1 having the above-described configuration can be a chair with good appearance because the shoulder massager 27 is covered with the back cover 4d . In addition, when the shoulder massage part 27 is not used, the shoulder massage part 27 stands as shown in FIG. 4, and the position adjusting body 28 made of an air bag and the air bag 32 making a massage element are both contracted. Is in a state. Therefore, various shoulder heights can be used in the same manner as a normal chair with a backrest, even when a person is seated, without the shoulder massage part 27 getting in the way.
[0057]
And since the position adjustment body 28 and the airbag 32 are shrink | contracted in this way, the internal pressure of the position adjustment body 28 and the airbag 32 does not increase too much with the weight received when sitting on the chair main body 2. FIG. Therefore, there is no fear that the durability of the position adjusting body 28 and the airbag 32 will be reduced.
[0058]
Further, in the first embodiment, it is possible to change the contents of the control designation when the pressing of the stop button 78 is continued for a certain time or more. For example, you may comprise so that each airbag 23,28,32 of the shoulder part massage apparatus 15 may be hold | maintained in the inflated state shown in the state of FIG. In this way, when the pillow element 28a is held in an inflated state even after the completion of all designated massage operations, it is easy for a specific user to perform shoulder positioning every time he / she is seated. Is good.
