Description

  The present invention relates to a rocking device that imparts an effect of loosening a body by rocking the body.

  Conventionally, a chair type massage machine capable of performing a massage operation on a seated user is known. Some of these chair type massage machines are provided with a foot receiving member for receiving both ankles of a user with respect to an ottoman on which the user's legs can be placed so as to be swingable in the left-right direction. Yes (see, for example, Patent Document 1).

  In the chair type massage machine described in Patent Document 1, an attachment plate to which a foot support member is attached is provided so as to be slidable in the left-right direction. Since this mounting plate is connected to a rotating shaft of a motor as a drive source so that power can be transmitted, when the rotating shaft of the motor is driven to rotate, the footrest member is based on the driving force transmitted from the motor. Slide left and right with the attached. As a result, as the footrest member receiving the user's ankle part reciprocates in the left-right direction, the lower body of the user's legs (the entire leg) swings around the user's waist. By exercising, the tension state of the user's leg is relieved.

  In addition, a pair of left and right eccentric rollers are provided on the back portion of the chair type massage machine described in Patent Document 1. Of the pair of eccentric rollers, when the left eccentric roller rotates so as to protrude to the surface side of the backrest portion, the footrest member moves to the left, while the right eccentric roller moves to the surface side of the backrest portion. If it rotates so that it may protrude, a footrest member will move to the right.

  As a result, when the user's lower body swings to the left, the user's upper body is rotated to the right, while when the user's lower body swings to the right, the user's upper body is rotated to the left. In other words, since the twisting action acts on the user's body greatly in synchronization with the rotation action of the eccentric roller and the swinging action of the footrest member, the feeling of movement having the effect of loosening the larger body is achieved. Different swinging operations are performed.

  In addition, the ottoman 15 is provided with a total of two leg support portions 18 having a concave shape into which the user's legs can be inserted. Then, as shown in FIG. 3, each leg support 18 swings in the left-right direction when the swing driving unit 19 is driven and controlled based on a control command from the control unit 17.

  Moreover, as shown in FIG.1 and FIG.2 (a), the backrest part 13, the seat part 12, and the left-right paired leg part support part 18 press a part of a user's body, a body axis A back part turning part 20, a waist part turning part 21, a seat part turning part 22, and a leg part turning part 23 that are rotated around are provided. In addition, since the structure of these rotation parts 20-23 is substantially the same, in the following description, the leg part provided in the seat part rotation part 22 provided in the seat part 12, and the leg part support part 18 is provided. The configuration of the rotating unit 23 will be described.

  As shown in FIG. 2 (a), the seat rotating section 22 includes a rotating member 24 having a concave curved surface seat surface on which the user's buttocks sit. The substantially central portion of the rotating member 24 in the left-right direction is pivotally supported by a rotating shaft 25 that passes through the lower end portion of the backrest portion 13 back and forth. Further, an air bag 26 as an inflating means is provided on the upper surface of the seat portion 12 so as to be interposed between the lower surface of the rotating member 24 and the left and right surface portions with respect to the user's body axis. Yes. The airbag 26 is arranged in a state where it is vertically overlapped. These airbags 26 are inflated and contracted by driving and controlling an air pump 28 (see FIG. 3) based on a control command from the control unit 17.

  Moreover, as shown in FIG.2 (b), the leg rotation part 23 is provided with the rotation member 30 which has the concave curved surface-shaped support surface in the front side which can support a user's calf. The substantially central portion of the rotating member 30 in the left-right direction is vertically inserted through the distal end portion of the extending member 31 that extends forward from the inner bottom surface 18a located in the inner space between the side walls of the leg support portion 18. Is pivotally supported by a rotating shaft 32 that rotates. Further, on the inner bottom surface 18 a of the leg support portion 18, airbags 33 as inflating means are respectively provided so as to be interposed between the respective surface portions on the left and right sides on the rear surface of the rotating member 30. The airbag 33 is arrange | positioned in the state overlaid on the front and back double. These airbags 33 are inflated and contracted when the air pump 28 is driven and controlled based on a control command from the controller 17.

  Further, as shown in FIG. 2B, the swing drive unit 19 includes a motor 34 whose drive is controlled by the control unit 17 and a rotational driving force of the motor 34 in the left-right direction (straight line). And a linear motion conversion mechanism 35 that converts motion).

The link member 38 is rotatably connected to a part in the circumferential direction and a base end side of a rotating member 34 a provided in a coaxial arrangement at the tip of a rotating shaft (not shown) of the motor 34. For this reason, when the rotating shaft of the motor 34 rotates, the base end side of the link member 38 is rotationally moved, and the distal end side thereof moves in the left-right direction, so that the connection base portion 37 moves along the guide rail 36 in the left-right direction. It is designed to move in the direction. As described above, the connecting base portion 37 moves in the left-right direction along the guide rail 36, so that the leg support portion 18 of the ottoman 15 swings integrally.

Next, the operation of the massage machine 10 configured as described above will be described below, particularly focusing on the operation when the user's seating posture is changed during the swinging operation of the user's legs.
Now, in the massage machine 10 of the present embodiment, when the swinging stimulus by the swinging operation is given to the body of the user seated on the seat 12, the control unit 17 first drives and controls the swing driving unit 19. . Then, each leg support 18 swings left and right, and the user's leg K supported by these leg support 18 also swings left and right in conjunction with each leg support 18. To do. In the present embodiment, the swing drive unit 19 is based on the driving force transmitted from the motor 34, and each leg support unit 18 swings at a frequency of about 1 to 10 Hz (1 to 10 reciprocations per second). Do dynamic exercise. Therefore, a rocking stimulus that shakes muscles acts on the leg K of the user.

  And when changing the transmission aspect of the rocking | swing irritation | stimulation with respect to a user's body, the control part 17 is the back part rotation part 20, the waist part rotation part 21, the seat part rotation part 22, and the leg part rotation part 23. Drive one of them.

  Here, it is assumed that the control unit 17 drives and controls the seat rotation unit 22. Then, as shown in FIG. 4A, the seat rotating portion 22 is one of the airbags 26 provided on the left and right sides of the rotating member 30 (the right side in FIG. 4A). The airbag 26 on the other side (left side in FIG. 4A) starts the contracting operation while the airbag 26 starts the expanding operation. The rotating member 24 is rotated upward in the clockwise direction when viewed from the front with the rotating shaft 25 as a center by being pressed upward by the airbag 26 on the one side being inflated. As a result, the seating posture of the user changes so that the buttocks of the user seated on the rotating member 30 rotate in the same direction around the body axis.

  Further, when the amount of inflation of the airbag 26 on one side reaches the maximum inflation amount corresponding to the maximum pressing amount against the user's body, the seat portion rotating portion 22 performs the contraction operation after maintaining the inflated state for a predetermined time. Migrate to Then, the airbag 26 on the other side in the contracted state starts an inflating operation. Then, as shown in FIG. 4B, the turning member 24 is pressed upward by the airbag 26 on the other side that is inflating, thereby turning counterclockwise around the turning shaft 25 as viewed from the front. Rotate in the direction. As a result, the seating posture of the user changes so that the user's buttocks seated on the rotating member 24 rotates in the same direction around the body axis.

  That is, the seating posture of the user during the swinging motion of the leg K varies in various ways according to the turning angle of the user's buttocks to the left and right. Therefore, the transmission mode of the swing from the user's leg K to the upper body varies in various ways. And the rocking | fluctuation irritation | stimulation of the motion different from before performing rotation operation of the seat part rotation part 22 is provided as an effect which loosens a body with respect to a user's body.

  In particular, in the present embodiment, the control unit 17 stops the driving of the air pump 26 when the inflation amount of the airbag 26 reaches a preset target inflation amount (in this case, the maximum inflation amount). The expanded shape is maintained at a predetermined size. That is, the seating posture of the user is maintained in a state where the entire leg portion K is rotated left and right as viewed from the front. For this reason, a swinging stimulus having an operational feeling different from that before performing the rotating operation of the seat rotating unit 22 is given to the user's body as an effect of continuously loosening the body within a certain time.

  Further, it is assumed that the control unit 17 drives and controls the leg rotation unit 23. Then, as shown in FIG. 5A, each leg rotation part 23 provided on the pair of left and right leg support parts 18 is one of the airbags 33 provided on the left and right sides of the rotation member 30. The airbag 33 on the side (right side in FIG. 5A) starts inflating operation, and the airbag 33 on the other side (left side in FIG. 5A) starts contracting operation. Then, the rotating member 30 is rotated in the counterclockwise direction as viewed from above around the rotating shaft 32 by being pressed forward by the airbag 33 on the one side being inflated. As a result, the seating posture of the user changes so that the user's leg K supported by the rotating member 30 rotates in the same direction around the body axis.

  In addition, when the inflation amount of the airbag 33 on one side reaches the maximum inflation amount, the leg rotation portion 23 shifts to a contracting operation after maintaining the inflated state for a predetermined time. Then, the airbag 33 on the other side in the contracted state starts an inflating operation. And as shown in FIG.5 (b), the rotation member 30 is rotated in the clockwise direction seeing from upper direction by being pressed ahead by the airbag 33 of the other side inflating. As a result, the seating posture of the user changes so that the user's leg K supported by the rotating member 30 rotates in the same direction around the body axis.

  That is, the seating posture of the user during the swinging motion of the leg K changes more variously according to the angle of the user's leg K turning left and right. Therefore, the transmission mode of the swing from the user's leg K to the upper body varies in various ways. Then, when the leg rotation unit 23 is not rotated or when the seat rotation unit 22 is rotated, a swinging stimulus with a different operational feeling is given to the user's body as an effect of loosening the body.

According to the first embodiment, the following effects can be obtained.
(1) The user's body is gently rotated about the axis extending in the body axis direction so that the posture of the user changes with the inflating operation of the airbags 26 and 33. Therefore, it is possible to variously change the operational feeling of the swinging operation that acts on the user's body during the swinging operation of the leg K, while avoiding discomfort to the user.

  (2) Since the airbags 26 and 33 are disposed on both the left and right sides of the body axis of the user's body, the user's body is smoothly rotated in both the left and right directions as the airbag 33 is inflated. be able to.

(3) Since the rotation members 24 and 30 rotate while being in close contact with a part of the user's body, the user's body can be rotated more smoothly.
(4) The rotation members 24 and 30 are configured to be rotatable about rotation shafts 25 and 32 extending in the body axis direction of the user. For this reason, the rotating operations of the rotating members 24 and 30 are smoothly performed, so that the user's body can be rotated more smoothly.

  (5) The airbags 26 and 33 are disposed on the left and right sides of the rotating members 24 and 30. Therefore, as the airbags 26 and 33 are inflated, the rotating members 24 and 30 that support the user's body can be smoothly rotated left and right, so that the user's body can be rotated more smoothly. It can be carried out.

  (6) The control part 17 can provide sufficient irritation | stimulation with respect to a user's body by maintaining the inflation state of the airbags 26 and 33 and maintaining the rotation state of a user's body.

  (7) Since the airbags 26 and 33 are provided on the seat portion 12 and the leg support portion 18, the operation feeling that acts on the lower body of the user with the swinging motion of the leg K is given to the lower body of the user. Various changes can be made by inflating the airbags 26 and 33 provided corresponding to the portions.

  (8) The swing driving unit 19 transmits the driving force from the motor 34 to the leg support unit 18 to swing the leg support unit with a relatively short period that causes the muscles of the leg K to shake. Therefore, in accordance with the swinging motion of the leg K, it is possible to apply a stimulus that relaxes the muscle tension of the leg K.
