  In the above example, which has been widely known in the past, a rising wall is provided on one or both sides of the armrest, and the position where the user places the arm on the armrest is restricted even when arm massage is not used. I felt cramped and could not relax. Moreover, since the width | variety of the groove part for treatment comprised by the standing wall is fixed, there existed a problem that a massage feeling will differ with the thickness of a user's arm.

  Further, in the above-mentioned example as conventionally known, since the hands and arms are pressed with the surface, a soft feeling of treatment is obtained, and there is a problem that some users feel unsatisfactory. Further, in the above example, there is a problem that the massage feeling is weak for grasping the arm from the upper surface because it is a massage from the rising walls on both sides.

  The present invention has been invented in view of the above-described conventional problems, and it is an object of the present invention to provide a chair-type massage machine in which the position where the arm is placed is not limited when it is not used for hand or arm massage. It is an object to provide a chair type massage machine that can perform point stimulation for a user who is unsatisfactory with a sense of irritation, and to provide a chair type massage machine that can massage to grasp the arm from the upper surface Is.

In order to solve the above problems, a chair-type massage machine according to the present invention is a chair-type massage machine equipped with a seat surface, a backrest, and an armrest, and is provided with a cover piece that opens and closes up and down on the upper surface of the armrest body of the armrest. A massage means is provided on at least one of the lower surface of the armrest and the upper surface of the armrest body, and the massage means is driven while keeping a hand or arm sandwiched between the lower surface of the cover piece and the upper surface of the armrest body. In addition, the cover piece is closed and the massage means is not driven so that the upper surface of the cover piece becomes an armrest surface, and the cover piece includes an urging means for urging the cover piece in the opening and closing direction, The magnitude of the force urged by the urging means varies depending on the opening / closing position of the cover piece, and the force of the urging means and the weight of the cover piece are balanced between the open / close movable ranges of the cover piece. There, when the cover piece is opened from the balanced position the force in the upward direction is greater than the weight of the cover piece by the biasing means, when the cover piece is closed from balanced position upward by the biasing means It is characterized in that the force is smaller than the weight of the cover piece.

When you massage your hand or arm, open the cover piece, put your hand or arm between the cover piece and the upper surface of the armrest body, keep the hand or arm sandwiched, and drive the massage means. You can massage your arms. In addition, when massage is not performed by driving the massage means, the arm can be placed on the armrest surface on the upper surface of the cover piece by closing the cover piece, and the position where the arm is placed is not limited, so there is no feeling of cramping You will be able to relax. In addition, once the cover piece is opened, it will not close naturally due to the weight of the cover piece, so a series of actions for arm massage that opens the cover piece and puts hands and arms between the cover piece and the armrest body. However, it can be easily done with only one hand. If the massage means performs pressure massage with an air bag, the cover piece will open and close continuously when the user is absent and left in a state where the air bag is repeatedly expanded and contracted. This eliminates the possibility of extending the service life. Furthermore, since the weight of the cover piece is canceled by the urging means, it is possible to reduce the operating force for opening the cover piece.

  It is also preferable that the cover piece can be held in a closed state when the massage means is driven and the hand or arm is not massaged. In this case, the arm can be stably placed on the armrest surface on the upper surface of the cover piece that is kept closed, and the arm can be further relaxed.

  It is also preferable that the cover piece be opened upward while rotating about a fulcrum provided in front of the armrest body. In this case, the distance between the upper surface of the armrest body and the lower surface of the cover piece is narrower toward the front of the armrest body and wider toward the rear of the armrest body, which is similar to the thickness change from a person's fingertip to the arm. When performing massage with an air bag as a means, it becomes possible to apply pressure to the human body with a small amount of air, and the energy consumption of the device can be suppressed. In addition, by shortening the time required for intake and exhaust, a more effective tempo and good massage can be achieved. Also, when the massage means performs massage that pushes in and out of the treatment body and presses the human body, the required protrusion amount of the treatment body can be reduced, so that the size of the drive mechanism of the massage means can be further reduced, It leads to weight reduction and design improvement.

  It is also preferable that the fixing angle when the cover piece is opened can be adjusted. Since the fixed angle when the cover piece is opened can be adjusted, the user can adjust the opening / closing amount according to the thickness of the arm, and the compression force of the constant arm massage regardless of the thickness of the arm , Compression time will be obtained. Even if the pressure applied by the massage means is constant, increasing the opening amount of the cover piece makes the massage force feel weaker, and reducing the opening amount of the cover piece makes the massage force feel stronger. Therefore, strength adjustment can be realized more easily without performing output control of the massage means.

  It is also preferable that the massage means is provided with a protrusion for applying a point push to the hand or arm. In this case, it is possible to perform point stimulation with massage means from the top and bottom of the upper surface of the armrest body and the opposing surface of the cover piece in a posture that is normally sitting on a chair and placing hands and arms on the armrest. A feeling of massage treatment can be given to the user.

  In addition, it is also preferable that a protrusion is provided at a position where the urn of the palm of the hand is pressed. In this case, it is possible to effectively squeeze the pot of Aiya, which is said to adjust the function of the large intestine.

  It is also preferable that a positioning mechanism is provided on the protruding portion so as to match the pot of the valley. In this case, even if a hand is inserted between the cover piece and the armrest main body with the cover piece opened, the protrusion and the palm valley can be easily aligned with each other without visual confirmation. As a result, it is possible to prevent point irritation caused by the protrusions on the wrong position of the back of the hand.

  Moreover, it is also preferable that the massage which grasps an arm is possible by the at least 2 massaging means with which the upper surface of the armrest main body and the lower surface of the cover piece were opposed. In this case, it is possible to solve the problem that the feeling of massage for grasping the arm from above is weak.

  It is also preferable that at least two massage means are on both sides of the center line of the arm, and the center line side of the massage means is fixed. In this case, it is possible to perform a massage of grasping the arm from the outside so that a person actually massages the muscle of the upper part of the arm (arm flexor muscle), which is considered to be particularly tired.

  It is also preferable that the massage means is provided with a position adjusting means for preventing the position of the treatment position from being shifted relative to the arm. In this case, a difference in massage feeling due to the thickness of the arm (for example, a thick person hurts and a thin person is weak) can be given, and any person can give a stable massage feeling.

In the present invention, when hand or arm massage is performed as described, the cover piece is opened, the hand or arm is inserted between the cover piece and the upper surface of the armrest body, and the massage means is maintained while holding the hand or arm. By driving, you can massage your hands and arms, and when you do not massage by driving the massage means, you can put the arm on the armrest surface on the upper surface of the cover piece by closing the cover piece Yes, you can relax without feeling cramped because the position where you put your arm is not restricted . Moreover, once the cover piece is opened, it does not close naturally due to the weight of the cover piece, so a series of operations for arm massage is performed by opening the cover piece and putting hands and arms between the cover piece and the armrest body. Easy to do with one hand. If the massage means performs pressure massage with an air bag, the cover piece will open and close continuously when the user is absent and left in a state where the air bag is repeatedly expanded and contracted. This eliminates the possibility of extending the service life. Furthermore, since the weight of the cover piece is canceled by the urging means, it is possible to reduce the operating force for opening the cover piece.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. First, an example of the embodiment shown in FIGS. 1 to 5 will be described.

  As shown in FIG. 1, the chair 1 is mainly composed of a backrest 2, a seat surface 3, an armrest 4, and an ottoman 5, and a cover piece that can be opened and closed by turning up and down on the upper surface of the armrest body 4a of the armrest 4. 6 is provided. Massage means 7 and 8 are provided on the lower surface of the cover piece 6 and the upper surface of the armrest body 4, respectively. In the case of this example, the massage means 7 and 8 are inflatable and shrinkable air bags, and air is supplied from the compressed air supply means 23 through the air supply pipes 21 and 22. In the case of this example, the massage means 7 and 8 are air bags that are inflated by compressed air and pressurize the human body. However, the massager may enter and exit the treatment body to press and massage the human body. The upper surface of the cover piece 6 is a smooth surface substantially parallel to the upper surface of the armrest body 4a to form a normal armrest surface.

  In the example shown in FIGS. 1 to 3, the cover piece 6 is rotatably supported by a pin 10 on a fulcrum 9 provided in front of the armrest body 4 a, and the cover piece 6 is raised and lowered at the front center. It opens and closes. As another example of the opening / closing method of the cover piece 6, the one shown in FIGS. 4 and 5 may be employed. In the structure shown in FIG. 4, the armrest body 4a is opened while rotating in the chair outer direction around a fulcrum 24 provided on the outer side in the width direction. In the case shown in FIG. 5, the cover piece 6 is opened while being moved while maintaining substantially the same angle by the pair of links 25 and the link fulcrum 26 provided on the cover piece 6 and the link fulcrum 27 provided on the armrest body 4a. It has become.

  When hand or arm massage is performed with the user sitting on the chair 1, for example, as shown in FIG. 2, the cover piece 6 is opened and the hand or arm is inserted between the cover piece 6 and the armrest body 4a. Hands and arms are sandwiched between the piece 6 and the armrest body 4a, and the massage means 7 and 8 are driven to massage the hands and arms. When hand or arm massage is not performed, for example, as shown in FIG. 3, the cover piece 6 is closed, and the hand or arm is placed on the upper surface of the cover piece 6 and used as a normal armrest. Thus, when the cover piece 6 is closed when the hand or arm is not massaged, the position where the hand or arm is placed is not limited, so that the user can relax without feeling cramped. When the cover piece 6 is opened and hand or arm massage is performed, the cover piece 6 can be opened upward while rotating around a fulcrum 9 provided in front of the armrest body 4a as shown in FIG. In this case, the distance between the upper surface of the armrest main body 4a and the lower surface of the cover piece 6 is narrower toward the front of the armrest main body 4a and wider toward the rear of the armrest main body 4a, similarly to the change in thickness from the human fingertip to the arm. Therefore, when performing massage with an air bag as the massage means 7 and 8, it becomes possible to apply pressure to the human body with a small amount of air, and the energy consumption of this device can be suppressed. In addition, by shortening the time required for intake and exhaust, a more effective tempo and good massage can be achieved. In addition, when performing massage that pushes the human body in and out of the treatment body, the required protrusion amount of the treatment body can be reduced, so that the size of the drive mechanism can be made smaller, weight reduction, and design improvement. Leads to.

  As shown in FIGS. 2 and 3, the armrest body 4a is provided with slits 11 along the moving direction of the cover piece 6, and the stay 17 attached to the cover piece 6 is provided with pins 12. A pin 12 is slidably inserted into the slit 11, and the opening / closing movable range of the cover piece 6 is determined by the slit 11 and the pin 12. Between the pin 12 and the pin 14 mounted on the fulcrum 13 provided on the armrest body 4a, a biasing means 15 for biasing in the direction of increasing the distance between the pin 12 and the pin 14 is provided. The fulcrum 9 and the fulcrum 13 are located below the straight line connecting the fulcrum 9 and the fulcrum 13 when the cover piece 6 is completely closed, and when the cover piece 6 is opened, the pin 12 is It is provided so as to be located above the line connecting the fulcrum 9 and the fulcrum 13. Therefore, when the pin 12 is positioned above the fulcrum 9 and the fulcrum 13 as shown in FIG. 2, a force is applied in the direction in which the cover piece 6 opens, and as shown in FIG. If the position is below the straight line connecting the fulcrum 13 and the fulcrum 13, a force is applied in the direction in which the cover piece 6 is closed. In a state where the cover piece 6 is completely opened as shown in FIG. 2, the force by the urging means 15 is larger than the weight of the cover piece 6. That is, by configuring as described above, the magnitude of the force urged by the urging means 15 changes depending on the opening / closing position of the cover piece 6, and the urging means 15 is between the opening / closing movable ranges of the cover piece 6. When the cover piece 6 is balanced with the weight of the cover piece 6 and the cover piece 6 is opened from the balanced position, the upward force by the biasing means 15 is larger than the weight of the cover piece 6, and the cover piece 6 is more than the balanced position. When closed, the upward force by the urging means 15 is made smaller than the weight of the cover piece 6. The biasing means 15 can be implemented by a generally known spring, rubber or the like utilizing a repulsive force or magnetic force, or a cylinder and piston enclosing a high-pressure fluid.

When the cover piece 6 is opened once when it is urged by the urging means 15 as described above, the cover piece 6 is not naturally closed by the weight of the cover piece 6, so the cover piece 6 is opened and the cover piece 6 is opened. A series of actions for massaging the hand and arm by putting the hand and arm between the arm and the armrest body 4a can be easily performed with only one hand. Further, when the massage means 7 and 8 perform pressure massage with an air bag, the cover piece 6 is continuously formed when the user is absent and left in a state where the air bag is repeatedly expanded and contracted. Opening and closing operations are no longer performed, and the service life can be extended. Furthermore, since the weight of the cover piece 6 is offset by the urging means 15, the operating force for opening the cover piece 6 can be reduced.

  6 and 7, the fixing angle of the cover piece 6 when the cover piece 6 is opened can be adjusted. In the case shown in FIG. 6, the slit 11 is provided with a plurality of locking grooves 16 in a direction different from the direction in which the cover piece 6 moves in the opening and closing direction (direction substantially orthogonal). A stay 17 is rotatably attached to the cover piece 6 at a fulcrum 18, and a pin 12 attached to the stay 17 is inserted into the slit 11, and the tip of the pin 12 projects outside the armrest body 4a. is there. When the opening / closing angle of the cover piece 6 is in a position where the pin 12 and the locking groove 16 correspond to each other, the cover piece 6 is fixed by operating the tip end of the pin 12 and inserting the pin 12 into the locking groove 16. The That is, the cover piece 6 is fixed by locking the pin 12 in the appropriate locking groove 16 in a state where the cover piece 6 is opened and closed and set to an arbitrary angle. Further, in the case shown in FIG. 7, a screw portion 19 is provided on the pin 12 inserted through the slit 11 of the stay 17 so that the cover piece 6 can be fixed at an arbitrary position by tightening the nut 20. It has become.

  If the fixed angle when the cover piece 6 is opened as in the example of the embodiment of FIGS. 6 and 7 can be adjusted, the user can adjust the opening / closing amount according to the thickness of the arm. Regardless of the thickness, you can obtain a certain massage pressure and time. Even if the compression force by the massage means 7 and 8 is constant, if the opening amount is increased, the massage force is felt weakly, and if the opening amount is decreased, the massage force is felt strongly, Without performing output control of the massage means 7 and 8, strength adjustment can be realized more easily.

  Next, an example of the embodiment shown in FIGS. 8 to 12 will be described. This example is the same as the example of the embodiment shown in FIGS. 1 to 5, and the description of the same part is omitted, and only the different points will be mainly described. Massage means 7 and 8 are provided on the upper surface of the armrest body 4 a and the lower surface of the cover piece 6, but a protrusion 30 for applying point pressing of the hand or arm is provided on the massage means 7 and 8. In the case of this example, the protrusion 30 is provided on the massage means 7 on the lower surface of the cover piece 6. In the case of this example, the projection 30 includes a hand projection 30a that pushes the heel 31 of the palm of the palm of the hand and an arm projection 30b that pushes the arm. Even if the protrusion 30 is provided as described above, the cover piece 6 may be rotatably supported by the pin 10 on the fulcrum 9 provided in front of the armrest body 4a as shown in FIGS. As shown in FIG. 12, even if the cover piece 6 is opened while rotating in the chair outer direction around a fulcrum 24 provided on the outer side in the width direction of the armrest body 4 a, the cover piece 6 has a pair of links 25 as shown in FIG. 12. Also, the link fulcrum 26 provided on the cover piece 6 and the link fulcrum 27 provided on the armrest body 4a may be opened while moving while maintaining substantially the same angle.

  Ordinarily sitting on the chair 1 and putting your hands and arms on the armrest 4, open the cover piece 6 and put your hand and arms between the cover piece 6 and the upper surface of the armrest body 4a and massage Driving the means 7 and 8 can massage the hands and arms. At this time, it is possible to give a point stimulus by pressing the hand or arm with the protrusion 30 and give the user a slightly tight feeling of massage treatment. The hand protrusion 30a can effectively squeeze the pot 31 that is said to adjust the function of the large intestine.

  In the example of FIG. 13, a positioning mechanism 32 is provided for aligning the hand projection 30 a with the pot 31 of the Goya. This positioning mechanism 32 is composed of a round bar 32a to which the cover piece 6 or the armrest body 4a is fixed, and the round bar 32a is addressed to the most concave portion of the concave curved portion 33 that connects the thumb of the hand and the base of the index finger. As a result, the hand projection 30a and the pot 31 of Aiya are matched. In this example, the positioning mechanism 32 is a round bar 32a. The positioning mechanism 32 is an elastic body such as a spring or a rubber string that is fixed to the cover piece 6 or the armrest body 4a and can be expanded and contracted according to the opening and closing of the cover piece 6. Also good. When the positioning mechanism 32 is provided in this way, the hand protrusion 30a and the valley are simply inserted by inserting a hand between the cover piece 6 and the armrest body 4a with the cover piece 6 open. The position of the pot 31 can be easily adjusted. Thereby, point stimulation by the protrusion part 30a for the hand to the wrong position of the back of the hand can be prevented.

  Moreover, in the example shown in FIG. 14, the projection part 30 is provided separately from the massaging means 7, and this projection part 30 is provided so that it can move in the direction along a hand or an arm. In the case of this example, the hand protrusion 30 a is movable as the protrusion 30. The hand projection 30a and the round bar 32a of the positioning mechanism 32 are integrally provided on the pedestal 34, and the round bar 32a is slidably attached to the slit 35 provided in the cover piece 6 or the armrest body 4a. If it does in this way, the protrusion part 30a for hands and the round bar 32a can be moved to the direction along a hand and an arm, and when the chair 1 is reclining, the position of the hand or arm with respect to the armrest part 4 will change. Also, the hand projection 30a and the round bar 32a can be moved accordingly. If it does in this way, even if it reclines backrest 2 later, the protrusion part 30a for hands can be match | combined with the pot 31 of Aiya, and point stimulation can be performed to the pot 31 appropriately.

  In the example shown in FIG. 15, the hand protrusion 30 a as the protrusion 30 and the round bar 32 a as the positioning mechanism 32 are interlocked with the reclining of the backrest 2. A seat frame 36 of the seat part 3 and a back frame 37 of the backrest 2 are rotatably connected by a reclining fulcrum 38. The hand projection 30a and the round bar 32a are movably attached to the slit 35, and the round bar 32a and the back frame 37 are connected by a link 39. If it does in this way, according to reclining of the backrest 2, the protrusion part 30a for hands and the round bar 32a will move interlockingly. Therefore, even if the user does not bother reclining or returning the backrest 2 and adjusting the position by moving the hand protrusion 30a, the hand protrusion 30a moves in conjunction with the backrest 2 and is used for the hand. The protrusion 30a matches the pot 31 of Aiya.

  In the example shown in FIG. 16, when the backrest 2 of the chair 1 is reclined, the entire armrest 4 is moved back and forth in conjunction with the backrest 2. The rear end of the armrest body 4 a of the armrest 4 is rotatably connected by a rotation shaft 40, and the front portion of the armrest body 4 a and the seat portion 3 are connected by a link 41. Accordingly, as shown in FIGS. 16A and 16B, the armrest 4 moves back and forth in conjunction with the reclining state of the backrest 2. As a result, the hand projection 30a as the projection 30 and the Aikiya pot 31 are interlocked with the backrest 2 and the armrest 4 is positioned at a position corresponding to the backrest 2 even when hand or arm massage is not performed. Easy to use as a normal armrest function.

  Next, an example of the embodiment shown in FIGS. 17 and 18 will be described. This example is also basically the same as the example shown in FIGS. 1 to 3, and common points will be omitted and only differences will be mainly described. Massage means 7 and 8 are provided on the lower surface of the cover piece 6 and the upper surface of the armrest body 4a. The massage means 7 provided on the lower surface of the cover piece 6 includes two massage means 7a and 7b arranged in the elbow width direction. ing. In the case of this example, these two massage means 7a and 7b are constituted by air bags 42 and 43 that can be expanded and contracted, so that air is supplied from the compressed air supply means 23 through the air supply pipes 21 and 22. It has become. The cover piece 6 is opened, the hands and arms between the cover piece 6 and the armrest body 4a are sandwiched, and the massage means 7a, 7b and the massage means 8 are driven to perform massage. As two massage means 7a, 7b, The two air bags 42 and 43 can be massaged so as to grasp the arm, and a strong massage can be performed. In the case of this example, the two massage means 7a and 7b are air bags 42 and 43 that are inflated by compressed air and pressurize the human body, but may be a method in which the treatment body enters and exits and presses the human body.

  FIG. 19 shows another example of the embodiment. The air bags 42 and 43 as the two massage means 7 a and 7 b are arranged on both sides of the center line of the arm 45 of the user, and the fulcrum 46 of the operation is located on the center line side of the arm 45. In this case, the air bags 42 and 43 are inflated so as to change from the state of FIG. 19A to the state of FIG. 19B, but the fulcrum 46 is on the center side of the arm 45 when the air bags 42 and 43 are inflated. Therefore, the massage which grasps the arm 45 from the outside can be performed, and an effective massage can be performed on the muscles of the upper part of the arm. That is, it is possible to perform a massage of grasping an arm that a person actually massages from the outside with respect to an upper arm muscle (arm flexor muscle) that is particularly easily fatigued of the human arm 45. Further, the massage means 7a and 7b have the same effect on means other than the air bags 42 and 43, such as a method in which a treatment body 50 as shown in FIG.

  As another example, as shown in FIG. 21, as the massage means 7 a, 7 b, a position adjusting means 47 for adjusting the position of the air bags 42, 43 is provided on the back of the air bags 42, 43. In contrast, the position of the air bags 42 and 43 can be adjusted to give a certain massage feeling. FIG. 21A shows the case of the thick arm 45, and FIG. 21B shows the case of the thin arm 45. Thus, in the case of adjusting the position of the air bags 42 and 43 by the position adjusting means 47, the difference in the massage feeling due to the thickness of the arm 45 (for example, a thick person hurts and a thin person is weak) can be eliminated. Even a person can give a stable massage feeling.

  As another example, as shown in FIG. 22, air bags 42 and 43 as massage means 7 a and 7 b are provided with a protruding treatment element 48, and give a stronger stimulus to a tired part of arm 45. An effective massage can be performed. In this way, in addition to the massage of the entire upper part of the arm 45, a stronger stimulation is given to the crucibles such as Tesatori, Kaikeike and Shitoku in the upper arm muscles (arm radius muscles). Can do.

  As another example, the position adjusting means 47 may be an inflatable and deflated air bag 47a as shown in FIG. In this case, the same drive source as that of the massage means 7a, 7b, 8 can be used as the drive means of the position adjusting means 46, and it is not necessary to provide another drive source, so that space saving for the device arrangement can be realized. Further, by using the air bag 46a, it is possible to give a soft massage feeling when performed by a person.
