JP 2004-344316 A

However, when returning the seat, etc. from the state where the seat, backrest and legs swing to the initial position, the swinging means operates regardless of the swing angle of the seat, backrest and leg. When this is done, the patient may feel uncomfortable and feel uncomfortable.
The object of the present invention is to provide an unnatural posture and uncomfortable feeling when the seat part and the leg part reclining to a desired angle are returned to the initial position, or between the leg part and the floor surface. The object is to provide a chair type massage machine in which no object is caught between them.

In order to solve the above problems, the chair type massage machine of the present invention is
A base that is placed on the floor, a seat that is swingably supported by the base, and a seat on which the user sits; a back that is swingably supported on the rear end side of the seat and on which the user's back hits The leg part, the leg part supported by the front end side of the seat part so as to be able to swing, the calf of the user being hit, the seat part swinging means for swinging the seat part, and the back part for swinging the backrest part Swing means, leg swing means for swinging the leg, seat swing means, backrest swing means, control means for controlling the leg swing means, and electrically to the control means An operating portion for operating the seat swinging means, the backrest swinging means and the leg swinging means connected,
The seat swinging means, the backrest swinging means and the leg swinging means comprise independent driving means controlled by the control means, respectively.
The operation part comprises an initial position button for returning the seat part, the backrest part and the leg part to a preset initial angle,
When the initial position button is operated, the control means swings the leg portion relative to the initial angle when the seat portion, the backrest portion, and the leg portion are inclined to return to a preset initial angle. If the angle is smaller than the swing angle relative to the initial angle of the seat, a drive means for the leg swing means is actuated to once swing in a direction opposite to the direction toward the initial angle. After the movement, the leg is swung in the direction toward the initial angle, and after the seat returns to the initial angle, the driving means is controlled to return the leg to the initial angle.

According to the chair type massage machine of the present invention, when the swing angle with respect to the initial angle of the leg is smaller than the swing angle with respect to the initial angle of the seat by a predetermined value or more, the leg is temporarily set to the initial angle. After swinging in the direction opposite to the heading direction, swinging in the direction toward the initial angle , the seat returns to the initial angle, and then the leg returns to the initial angle, resulting in an unnatural posture. Thus, it is possible to prevent the user from feeling uncomfortable and to prevent an object from being sandwiched between the leg portion and the floor surface.

  FIG. 1 is a side view of a chair type massage machine (10) of the present invention. In addition, in order to make an explanation easy to understand, a state in which an elbow rest on the near side is removed is shown.

  As shown in the figure, the chair type massage machine (10) is provided with a seat (20) on which a user sits on a base (12) placed on the floor (90), and the seat (20) A backrest (30) is provided at the rear end, and a leg (40) is provided at the front end of the seat (20).

  The seat part (20) is supported such that the rear end side of the seat part frame (22) to which a cushion or the like is attached is swingable with respect to the base frame (14), and the front end side serves as a drive means with a motor or an actuator. The seat rocking means (24) is connected. In the illustrated embodiment, a motor is used as the driving means. The seat (20) can be swung relative to the base (12) by operating the seat swinging means (24). A massage means (28) such as an airbag is provided in the seat (20).

  The backrest (30) can be swung relative to the seat (20) or the base (12) by a backrest swinging means (34) using a motor or an actuator as a drive means. In the illustrated embodiment, a motor is used as the driving means.

  In the illustrated embodiment, the backrest frame (32) is pivoted to the base (12) by a common shaft (16) with the seat frame (22). The backrest swinging means (34) has one end connected to the lower end of the backrest frame (32) and the other end connected to the front end of the seat frame (22). Therefore, when the seat portion (20) is swung, the backrest portion (30) swings integrally with the seat portion (20). Therefore, to swing only the seat (20) without swinging the backrest (30), the backrest (30) is opposite to the swinging direction of the seat (20). Must be swung.

  The backrest (30) can be swingably supported on the base (12), and the backrest swinging means (34) can also be configured such that the other end is connected to the base (12) side, In this case, the backrest (30) can swing independently of the seat (20). In order to swing the backrest (30) integrally with the seat (20), the backrest (30) may be swung in the same direction as the swinging direction of the seat (20). In the backrest (30), a known massage means (38) such as a treatment finger is arranged so as to be able to move up and down.

  The leg (40) is directly supported on the tip of the seat (20). A massaging means (48) such as an airbag is provided on the leg (40).

  The leg swinging means (44) for swinging the leg part (40) may be provided with a drive means such as a motor or an actuator in the seat part (20), or the leg part (40) may be placed in the seat part (20 ) And a drive means for the leg rocking means (44) may be provided on the base (12) in order to prevent the weight of the seat part (20).

  In the illustrated embodiment, the leg swinging means (44) uses a motor as the driving means, and the actuator (45) is attached to the frame (18) extending rearward from the lower surface of the front end of the seat (20). The actuator (45) is supported in a swingable manner in a plane parallel to the front-rear direction, and the tip of the actuator (45) is connected to a push-up frame (46) pivotally supported on the front lower surface of the seat (20). . A roller (47) is pivotally supported at the tip of the push-up frame (46), and the frame (42) of the leg portion (40) can contact the roller (47).

  When the actuator (45), which is the leg swinging means (44), is operated in the extending direction, the push-up frame (46) swings forward and upward, and pushes up the leg (40) forward. When the actuator (45) is actuated in the contracting direction, the push-up frame (46) moves backward and pushes down the leg (40). Since the leg frame (42) is only in contact with the roller (47) by its own weight, when the leg (40) is pushed down, an obstacle such as an article on the path of the leg (40) When an object is present, the roller (47) is separated from the leg frame (42), and the leg (40) is not further retracted.

  The swinging means (24) (34) (44) and the massage means (28) (38) (48) are connected to the control means (50) arranged at an appropriate position of the massage machine (10) by the drive circuit (52) ( 52) It is electrically connected via (52) and operates in response to a command from the control means (50). As shown in FIG. 5, the control means (50) includes a CPU, control circuits for the swing means (24), (34), and (44), a storage unit, and the like.

  FIG. 6 shows an operation unit (60) for performing various operations of the massage machine (10). The operation unit (60) is electrically connected to the control means (50), and the massaging means (28) (38) is provided by a plurality of buttons (61) to (68) provided on the operation unit (60). ) (48), and the swing angle (reclining angle) of the seat (20), the backrest (30), and the leg (40) can be appropriately adjusted. In addition, description is abbreviate | omitted about the operation method of massage means (28) (38) (48), the kind of operation | movement, etc.

  The reclining selection buttons (61), (62), and (63) of the operation unit (60) are seated at the `` pre-set reclining angle '' stored in the storage unit of the control means (50) for each button (20). The buttons actuate the swinging means (24), (34) and (44) so as to swing the backrest (30) and the leg (40). The operation button (64) is an initial position button for returning the reclining angle to a preset “initial angle (home position)”.

  When the reclining selection buttons (61) (62) (63) or the initial position button (64) are operated, the control means (50) activates the swing means (24) (34) (44), The seat part (20), the backrest part (30), and the leg part (40) are swung to the set angle. The angles of the seat (20), the backrest (30), and the leg (40) can be detected by a limit switch, an encoder, or the like.

  As shown in FIG. 1 and “home position” in FIG. 7 as the initial angle, the seat (20) is substantially horizontal with respect to the floor, and the backrest (30) and the leg (40) are A state substantially perpendicular to the seat (20) can be exemplified. The initial angle is stored in advance in the storage unit of the control means (50). The initial angle is an angle at which the user sits on the chair and easily stands up, and the initial position button (64) is operated to return the seat (20) to the initial angle.

  As a preset reclining angle, as shown by “Position 1” (POS1) in FIG. 7, the formation angle of the seat portion (20) with respect to the floor surface (90) is Z20 to 40 degrees, preferably about 30 degrees. The forming angle L between the part (20) and the backrest part (30) is 100 to 120 degrees, preferably about 110 degrees, and the forming angle K between the seat part (20) and the leg part (40) is 100 to 120 degrees, An example of the reclining angle is preferably about 110 degrees (see FIG. 2). Here, the directions of the formation angles Z, L, and K are as shown in FIG. That is, Z is an angle in a direction in which the front end of the seat (20) is raised with respect to the floor surface, L is an angle formed by the front side of the seat (20) and the backrest (30), and K is a seat. This is the angle formed by the back side of the part (20) and the leg part (40). This position 1 is an easy posture in which the user can sit down and have the least strain on the muscles and relax the whole body. The muscles on the front and back sides of the body are relaxed, and an effective massage effect can be obtained by operating the massage means (28) (38) (48) in this state. In order to move the seat (20) or the like to position 1, the reclining selection button (61) (POS1) is operated.

  As a reclining angle different from the above, as shown by “position 2” (POS2) in FIG. 7, the formation angle Z of the seat portion (20) with respect to the floor surface (90) is 20 to 40 degrees, preferably about 30 degrees. The formation angle L between the seat (20) and the backrest (30) is 110 to 130 degrees, preferably about 120 degrees, and the formation angle K between the seat (20) and the legs (40) is 130 to 160 degrees. The reclining angle is preferably about 140 degrees (see FIGS. 3 and 4).

  As shown in FIG. 8, the position 2 is a position where a massage can be received with a gentler posture than the position 1. Position 2 has a higher foot than Position 1, so in this state, the massage means (28) (38) (48) can be actuated to effectively massage the legs. It can remove the fatigue of the legs. In order to move the seat (20) or the like to position 2, the reclining selection button (62) (POS2) is operated. In position 2, it is possible to further improve the blood flow of the foot as a posture in which the foot tip is further raised and positioned above the heart and the knee is positioned below the heart.

  Position 2 lifts the user's leg higher than Position 1, so it does not move immediately from the initial angle, but instead reduces the burden on the user via Position 1 once. Is desirable.

  After swinging the seat (20) etc. at position 2, taking advantage of the posture of the user at position 2, that is, the blood flow of the leg is good, the massage means provided at the leg (40) According to (48), when the user's leg is massaged, an effective massage effect can be obtained. In this case, for example, as shown in FIG. 6, a leg raising lower body button (65) for operating the massage means (48) is provided in the operation unit (60) and the massage machine (10) is in the position 2 only. It is desirable that the button (65) is operable. Alternatively, it is possible to automatically shift to position 2 by operating the button (65). There is an advantage that not only the blood flow of the leg is improved but also the blood flow of the whole body can be improved by giving massage to the leg while keeping the leg in a high position.

  Further, as shown by “full flat” in FIG. 7, as an example of different reclining angles set in advance, the backrest (30) and the leg (40) are substantially horizontal with respect to the floor (90), Examples of the angle at which the seat (20), the backrest (30), and the leg (40) are in a substantially flat state. To move the seat (20) etc. to the full flat, the reclining selection button (63) (full flat) is operated. In the full flat, the chair is flat like a bed and the user can lie down and receive a massage.

  To move to position 1, position 2, and full flat position, you can move by operating the corresponding reclining selection buttons (61) (62) (63). It is also possible to switch between position 1, position 2, and full flat each time the button is pressed. In this case, if the reclining selection button is pressed again within a predetermined time, for example, 2 seconds after the reclining selection button is pressed, it is advantageous if the operation is accepted and switched so that the movement is not started for 2 seconds. .

  When the seat (20), etc. is returned to the initial angle from the position 1 and position 2, as well as the seat (20), backrest (30) and leg (40) swinging. When the swinging means (24) (34) (44) are operated regardless of the swinging angle of the head part (20), backrest part (30) and leg part (40), the posture becomes unnatural. The user may feel uncomfortable.

  Therefore, it is possible to detect the positional relationship between the seat (20) and the leg (40) in advance and adjust the leg (40) so that it does not return to the initial angle before the seat (20). desirable. For example, it is desirable to return the leg part (40) to the initial angle after the seat part (20) returns to the initial angle in advance.

  If the leg (40) maintains an initial angle with respect to the seat (20) or an angle close thereto, the leg (40) is once swung in the direction opposite to the original operation direction. After the lifting (lifting), the seat (20) may be swung toward the initial angle, and the leg (40) may be swung again toward the initial angle.

  Further, as shown in FIG. 9, the leg (40) is returned to the initial angle based on the angle Z of the seat (20) with respect to the floor and the angle K of the leg (40) with respect to the seat (20). You may change the timing.

  Specifically, when the user operates the initial position button (64), the swinging means (24), (34) (24), (34) of the seat part (20), the backrest part (30), and the leg part (40). 44) is activated and returns them to their initial angles. At this time, as shown in the flow chart of FIG. 10, the swinging means (24), (34) of the seat (20) and the backrest (30) has an initial angle of the seat (20) and the backrest (30). The operation is stopped in the direction of returning to (steps 10 to 13 and steps 14 to 17). On the other hand, as shown in the flow chart in FIG. 10, the leg (40) has a swinging means (44) based on the height of the leg (40) and the formation angle with respect to the floor (90) and the seat (20). Is activated.

  As shown in the flowchart of FIG. 10, the control means (50) first determines the height H (see FIG. 9) from the tip of the leg (40) to the floor surface (90) as the angle Z of the seat (20). Calculation is made based on the angle K of the leg (40) (step 1). If the calculated height H is lower than 10 cm, for example (step 2), it is unlikely that an object will be caught between the leg portion (40) and the floor surface (90). The swinging means (44) is actuated to lower the part (40) (step 6). When the initial angle is reached (step 7), the swinging means (44) is stopped (step 8) and the operation is finished. (Step 9).

On the other hand, when the height H of the leg 40 is 10 cm or more (step 2), the angle K of the leg 40 (FIG. 9).
For example, if the angle (see 3) is 120 degrees or less (step 3), the angle between the leg portion (40) and the seat portion (20) is so tight that the swinging means (44) of the leg portion (40) is temporarily set to the initial angle. Is swung so that the formation angle K between the leg portion (40) and the seat portion (20) is increased (step 4).

  In step 3, when the angle K of the leg (40) is larger than 120 degrees, or the rear swinging means (44) of step 4 is set so that the formation angle K of the leg (40) and the seat (20) is increased. In the state of being operated, the difference between the angle K and the angle Z is calculated, and the swinging means (44) is continuously operated until the difference exceeds, for example, 120 degrees (step 5).

  When the difference between the angle K and the angle Z exceeds 120 degrees (step 5), the swinging means (44) is operated so as to lower the leg (40) (step 6), and when the initial angle is reached (step 7). ), The swinging means (44) is stopped (step 8), and the operation is ended (step 9).

  As shown in the flowchart above, the tip of the leg (40) is high by changing the timing for returning the leg (40) to the initial angle based on the swing angle of the leg (40) with respect to the floor surface, etc. From the position, the initial angle does not return before the seat (20). Accordingly, it is possible to prevent an object from being sandwiched between the leg portion (40) and the floor surface (90).

  In the above embodiment, the leg (40) returns the leg (40) to the initial angle based on the formation angle K with the seat (20) and the height H of the tip of the leg (40). Although the timing is changed, the return timing may be changed based on one of them.

  When the backrest (30) is automatically tilted by the reclining selection switches (61) to (63), etc., the backrest (30) is slower than the swing speed in the direction that causes the swing speed in the tilting direction. It is desirable to control so that it does.

  When the speed in the direction of depressing the backrest (30) is increased, the user may feel a sense of fear by falling backwards. Therefore, it is desirable to reduce the speed in the direction of tilting the backrest (30). However, when swinging in the direction to raise the backrest (30), the treated person will get up in the forward direction, so there is no fear compared to when the backrest (30) is tilted, When the user wants to stand up quickly from the state where the backrest (30) has fallen, if the swing speed in the direction of raising the backrest (30) is slow, the user may feel frustrated or bothersome You may feel that.

  Therefore, the backrest (30) is controlled so as to be slower than the swing speed in the direction in which the swing speed in the tilting direction is generated. The raising / lowering speed of the backrest part (30) can be adjusted by changing the rotational speed of the motor of the swinging means (34) of the backrest part (30).

  Also, by lowering the speed at which the backrest (30) falls than the speed at which the seat (20) occurs (movement in the horizontal direction), for example, from the state where the seat (20) is most tilted The backrest (30) comes into contact with the floor (90) when the backrest (30) is tilted while raising the seat (20) (for example, when moving to full flat). And the limit switch can be prevented from chattering.

  More specifically, for example, when shifting from position 1 or position 2 in FIG. 7 to full flat, if the backrest (30) falls fast, the backrest is faster than the seat (20) becomes substantially horizontal. Since the part (30) reaches the floor surface, the limit switch is operated before reaching the floor surface to stop the falling operation of the backrest part (30). The seat (20) continues to rotate in the direction in which it rises even while the backrest (30) has stopped falling, and is integrated with this movement of the seat (20). ) Gets up again and the limit switch is released. When the limit switch is released, the backrest (30) is again driven in the tilting direction by the swinging means (34) and the chattering that the limit switch is activated again is repeated, but the backrest (30) Such a situation can be prevented by slowing down the falling speed. Further, when there is no limit switch, the backrest (30) can be prevented from reaching the floor surface.

  Furthermore, as described above, if the swinging speed when the backrest (30) is tilted is high, the user may feel a fear, but manual operation by operating the reclining button (68) Thus, when the backrest part (30) is tilted, the user can predict that the backrest part (30) will fall in advance. Therefore, in the case of manual operation, the backward tilting speed of the backrest (30) may be set to be faster than that of automatic, that is, swinging to position 1, position 2, or the like.

  By the way, in the embodiment as shown in FIGS. 1 to 4, that is, in the case where the backrest (30) swings integrally with the seat (20) when the seat (20) swings, the seat When the swinging means (24) of (20) and the swinging means (34) of the backrest (30) are actuated simultaneously, the speed of the backrest (30) relative to the floor surface becomes `` the speed of the seat relative to the floor surface ''. Speed ”+“ speed of the backrest relative to the floor surface ”, and the speed increases. Therefore, fear may be given when the backrest (30) falls, and discomfort may occur when the backrest (30) gets up.

  Therefore, in order to reduce the fear of giving to the user when the backrest (30) falls down, the seat (20) and backrest (30) are swung in the above-mentioned position 1 and position 2, full flat. When swinging the seat (20) and the backrest (30) to the initial angle (home position), the swing means (24) (24) of the seat (20) and the backrest (30) As shown in FIG. 11, the swinging means (24) of the seat portion (20) is first actuated to swing the seat portion (20) to a desired angle as shown in FIG. Thereafter, it is desirable to operate the swinging means (34) of the backrest (30) to swing the backrest (30) to a desired angle. On the contrary, as shown in FIG. 12, after the swinging means (34) of the backrest (30) is first actuated to swing the backrest (30) to a desired angle. Next, the swinging means (24) of the seat part (20) may be operated to swing the seat part (20) to a desired angle.

  Thus, by preventing the seat part (20) and the backrest part (30) from swinging at the same time, the user does not rapidly lean forward or lean forward as a whole, It becomes difficult to feel fear and discomfort. Further, as described above, there is an advantage that the instantaneous power consumption of the swinging means (24) (34) can be suppressed by not operating the swinging means (24) (34) simultaneously.

  Any of the reclining selection buttons (61) (62) (63) to position 1, position 2 and full flat and the initial position button (64) to the home position is operated, and each swing means (24 ) (34) (44) is in operation, any of the reclining selection buttons (61) (62) (63), initial position buttons (64), other reclining buttons (manual reclining button (68) Etc.), or when any one of the operation buttons is operated, the swing means (24) of the seat (20), the backrest (30) and the leg (40) (34) It is desirable to stop the operation of (44). Thus, when any of the buttons is operated with the swinging means (24) (34) (44) operating, the swinging means (24) (34) (44) is stopped. Therefore, safety can be improved.

  Further, a sensor (58) (see FIG. 5) that is electrically connected to the control means (50) and detects the presence or absence of the user is provided on the backrest (30) and / or the seat (20). If the patient is sitting on the massage machine (10), and if it is determined that there is no patient, any reclining selection button (61) (62) (63) or initial It is desirable to control so that the swinging means (24), (34) and (44) are not operated even when the position button (64) or the like is operated. As the sensor (58), a switch using a pressure sensor or an electrode can be exemplified.

  As described above, by restricting the operation of the swinging means (24), (34), and (44) depending on the presence or absence of the user, malfunction can be prevented and safety can be improved.

  In addition, the initial position button for the user to move the seat (20), the backrest (30) and the leg (40) to the home position during the treatment by the massage means (28) (38) (48). When the control means (50) is operated, the control means (50) stops the operation of the massage means (28), (38), and (48) and then operates the swinging means (24), (34), and (44). It is desirable to control as follows.

  The user usually operates the initial position button (64) when he wants to end the massage, so the seat (20), backrest (30) and legs (40) are in the home position. By stopping the operation of the massage means (28) (38) (48) before moving, the massage can be finished without a sense of incongruity, and when the seat (20) etc. moves to the home position The user can stand up smoothly.

  In addition, when the operation on / off switch (67) in FIG. 6 is in the “OFF” state, the operation buttons such as the reclining selection buttons (61) to (63) and the manual reclining button (68) are not accepted. It is convenient to accept only the position button (64) and return to the home position.

  In addition to the buttons (61) to (68) shown in FIG. 6 and the like, the operation unit (60) includes auxiliary operation units (70) of different sizes as shown in FIG. It is desirable to The auxiliary operation unit (70) is electrically connected to the control means (50). For example, the seat unit (20), the backrest unit (30), and the leg unit (40) are moved to the position 1 where the frequency of use is high. The initial operation (home position) of the operation button (71) for raising and lowering, the button for starting massage (72), the stop button (73), the seat (20), the backrest (30) and the leg (40) Only the initial position button (74) to return to can be provided.

  As described above, by providing a small auxiliary operation part (70) for performing a minimum operation, it is possible to select a desired operation even by groping during massage, and it does not interfere with massage. .
