The chair type massage machine of this embodiment has a seat part provided with sufficient width to support a user's buttocks from below, and a backrest part provided at the rear part of the seat part. As shown in FIG. 1, the backrest device 1 is provided inside the backrest portion for performing massage or hitting massage over a wide range from the user's shoulder to the waist through the back.

  The backrest device 1 includes guide portions 3 at both left and right ends of the backrest portion. The guide portion 3 is arranged so as to be parallel to the tilting direction of the backrest portion, and the base member 4 can be guided in the vertical direction along the arrangement direction of the guide portion 3. The base member 4 is attached with a massage mechanism 5 for performing massage or gripping massage on the user's treatment part.

  When the chair type massage machine is described in the following description, as shown in FIG. 1, the height direction of the backrest portion in the standing state is set as the vertical direction, and the horizontal direction and the front and rear are based on this vertical direction. Decide the direction and explain. These directions coincide with the up-down direction, the left-right direction, and the front-rear direction as viewed from the user seated on the chair type massage machine. In order to clarify the relationship between the direction in the figure and the direction in the actual apparatus, the typical figure shows the vertical direction (height direction), the horizontal direction (width direction), and the front-rear direction used in the description of this embodiment. Explicit.

Hereinafter, the backrest device 1 provided inside the backrest will be described first.
As shown in FIG. 1, the back massage device 1 described above includes a massage mechanism 5, a base member 4 that supports the massage mechanism 5, and a vertical movement mechanism 6 that moves the base member 4 in the vertical direction within the backrest portion. It has. In the backrest part, the base member 4 (massage mechanism 5) is moved up and down using the up-and-down movement mechanism 6 so that the height of the massage mechanism 5 corresponds to the user's treatment part (for example, the shoulder treatment part). The position can be adjusted.

  As shown in FIG. 2, the massage mechanism 5 is a member that enables the user to squeeze, beat and grab the treatment unit, and is attached to the base member 4 described above. The massage mechanism 5 includes a pair of left and right massage massage members 7 and 7 and a massage drive unit 8 that causes the massage massage members 7 and 7 on the left and right to perform massage massage operations. Further, the massage massage member 7 is provided with a grip massage member 10 provided on the proximal end side (or midway) of the massage massage member 7 and having a grip treatment element 9 at the distal end.

  As shown in FIGS. 3A and 3B, the massaging massage member 7 is a long plate member extending in an inclined manner from the lower front side of the massage mechanism 5 toward the front upper side and slightly outward. The proximal end side of the massaging massage member 7 is connected to a rotating shaft 11 provided in the left and right direction on the lower front side of the massage mechanism 5, and is shaken by rotating the rotating shaft 11 by a drive motor or the like. It is possible to move.

Further, the massaging massage member 7 is provided with a massaging treatment element 12 formed in a thick disk shape or a spherical shape using hard rubber, synthetic resin, or the like, and the massaging treatment element 12 is used. It is possible to massage the user's treatment department.
Further, on the proximal end side of the massaging massage member 7, there is provided a massaging boss portion 13 which is attached in an eccentric state to a rotating shaft 11 which is rotatably supported with respect to the base member 4 and has a cam surface formed on the outer peripheral surface. It has been. The massaging member 7 is inserted into the cam surface of the massaging boss portion 13 so that the base end side of the massaging massage member 7 can be freely rotated. It is configured to swing in the direction.

  In other words, in the above-described chair type massage machine, the cam surface of the left rubbing boss portion 13 and the cam surface of the right rubbing boss portion 13 have mutually symmetrical trajectories. Therefore, when the left massage body member 7 is guided along the cam surface and swings leftward, the right massage body member 7 swings rightward. In addition, when the left massage massage member 7 is guided along the cam surface and swings in the right direction, the right massage massage member 7 swings in the left direction.

Therefore, in the massaging massage member 7 described above, the massaging treatment elements 12, 12 of the left and right massaging massage members 7, 7 are brought close to or away from each other and sandwiched between the left and right massaging treatment elements 12, 12. Massage is given to the treatment department.
The grip massage member 10 described above is configured to bring the grip treatment element 9 close to and away from the massage treatment element 12 using the rotational driving force of the rotating shaft 11 of the massage massage member 7. The gripping massage member 10 is operated while gripping and transmitting the rotational driving force of the rotary shaft 11 to the massage member 10.

  As is disclosed in Japanese Patent Application No. 2014-36913 for which the applicant of the present application has already applied for a patent, the gripping drive unit 14 is attached to the rotating shaft 11 of the kneading massage member 7 in an eccentric state and has a cam on the outer peripheral surface. The base end is connected to the gripping boss portion 15 formed with a surface, the annular fitting portion 16 that fits into the cam surface of the gripping boss portion 15 and extracts the rotational driving force of the rotating shaft 11, and the annular fitting portion 16. And a crank member 17 that is gripped at its tip and connected to the massage member 10 and transmits the extracted rotational driving force to the massage member 10.

  The gripping massage member 10 is pivotally supported by the massage member 7 so as to be rotatable about the left-right axis with respect to the distal end provided with the gripping treatment element 9. In addition, the front end of the crank member 17 is connected to the midway side in the longitudinal direction of the gripping massage member 10 so as to be rotatable about an axis directed in the left-right direction. When the crank member 17 is moved in the extending direction, the gripping massage member 10 is moved. Is configured to swing back and forth.

In the massage mechanism 5 of the present embodiment, when the rotary shaft 11 is rotated, the grasping treatment element 9 repeats separation and proximity with respect to the massaging treatment element 12, and therefore, between the grasping treatment element 9 and the massaging treatment element 12. If the massage mechanism 5 is arranged so that the treatment part is located, for example, massage can be performed so that the treatment part such as a shoulder is grasped and held.
By the way, the base member 4 to which the above-described massage mechanism 5 is attached is moved in the vertical direction with respect to the backrest portion using the vertical movement mechanism 6. When the vertical movement mechanism 6 is used to move the base member 4 in the vertical direction, the vertical position of the massage mechanism 5 also changes.

For example, when a user's treatment part (for example, shoulder treatment part) is grabbed and massaged using the massage mechanism 5 described above, the position along the vertical direction of the massage mechanism 5 is set to a place corresponding to the user's treatment part. Need to align.
In the present embodiment, the treatment part is described as a shoulder, but is not limited to the shoulder. It may be waist. In addition, the “location corresponding to the user's treatment unit” includes not only the position of the user's treatment unit itself but also a position that serves as a reference for specifying the treatment unit.

  In particular, when the massage mechanism 5 for grasping and massaging is provided as in the chair type massage machine of the present invention, the grasping treatment element 9 and the massaging treatment element 12 may not be accurately aligned in the vertical direction and the front-rear direction. Must not. Therefore, the chair type massage machine of the present invention is provided with the vertical position detecting means for individually detecting the position of the user's shoulder (treatment part) and accurately determining the position corresponding to the shoulder.

  As disclosed in Japanese Patent Application Laid-Open No. 2007-97834 (Japanese Patent Application No. 2005-291600), this vertical position detecting means determines the swing angle of the massaging member 7 around the rotary shaft 11 to the rotary shaft 11 (facing in the left-right direction). The angle conversion unit 20 that converts the linear movement distance at a position away from the axis), the distance measurement unit 21 that measures the linear movement distance converted by the angle conversion unit 20, and the linear movement distance measured by the distance measurement unit 21. And a shoulder position detector for detecting the shoulder position of the user. That is, the vertical position detection means measures the linear movement distance of the massage mechanism 5 with respect to the base member 4 described above, and the tip of the massaging massage member 7 (the massaging treatment element 12) is based on the measured linear movement distance. It is configured to determine whether the shoulder position is touched, in other words, whether the vertical position of the massage mechanism 5 is at the shoulder position.

  Specifically, as shown on the right side of FIG. 4, the proximal end side of the massaging member 7 described above protrudes in the direction opposite to the direction toward the distal end (the direction toward the massaging treatment element 12). A protruding piece 23 is formed. A joint arm 24 is pivotally supported at the tip of the protruding piece 23 via a ball joint. The joint arm 24 is a long rod-like member curved in an arc shape, and one end in the longitudinal direction is on the tip of the protruding piece 23 described above, and the other end in the longitudinal direction is on the left and right side surfaces of the massage mechanism 5 described above. , And are connected so as to be rotatable about an axis facing the left-right direction. The joint arm 24 serves as the angle conversion unit 20 described above.

  The distance measuring unit 21 measures a relative movement distance of the massage mechanism 5 with respect to the base member 4, a photo interrupter 25 provided on the base member 4, a detection light shield 26 provided on the massage mechanism 5, The relative movement distance is measured according to how much the light irradiated from the photo interrupter 25 is shielded by the detection light shield 26.

  The shoulder position detection unit is a member that detects the shoulder position of the user based on the linear movement distance (relative movement distance of the massage mechanism 5 with respect to the base member 4) measured by the distance measurement unit 21. Specifically, the shoulder position detection unit determines that the shoulder position of the user has been detected when there is a large change in the linear movement distance measured by the distance measurement unit 21 that exceeds a preset threshold. It has a configuration.

In addition, in the chair type massage machine of the present invention that employs the massage mechanism 5 that performs the grip massage, if the position of the grip treatment element 9 or the massage treatment element 12 is shifted in the front-rear direction as described above, It becomes difficult to sandwich a treatment part such as a shoulder between the grasping treatment element 9 and the treatment part cannot be sufficiently grasped and massaged.
Therefore, in the chair type massage machine of the present invention, in order to align not only the vertical direction but also the longitudinal direction as well as the grasping treatment element 9 and the massaging treatment element 12, the above-described vertical position detection means corresponds to the user's treatment part. After detecting the position (for example, the shoulder position), a back-and-forth movement mechanism for moving the massaging massage member 7 further in the front-rear direction at a position determined by the vertical position detection means to be “a position corresponding to the treatment portion” is provided. It has become a thing.

As shown in FIG. 5, the back-and-forth movement mechanism swings the massaging massage member 7 back and forth by moving the massage mechanism 5 in the vertical direction with respect to the base member 4. The back-and-forth movement mechanism is provided with massage mechanism moving means for moving the massage mechanism 5 in the vertical direction with respect to the base member 4.
That is, the guide rail 29 is provided on the base member 4 in the vertical direction. Two guide rails 29 are provided, one on each of the left and right sides of the base member 4. The guide rail 29 penetrates the base member 4 in the vertical direction, and the base member 4 is arranged so as to be slidable in the vertical direction along the guide rail 29.

  For example, when the massage mechanism 5 is moved upward with respect to the base member 4 using the massage mechanism moving means described above, the massage massage member 7 connected to the massage mechanism 5 via the joint arm 24 also moves upward. try to. However, the rotation shaft 11 of the massage massage member 7 is fixed so as not to move with respect to the base member 4 by using the shaft support portion 30. Therefore, when a force is applied upward to the joint arm 24, a force is applied to the tip of the protruding piece 23 that is spaced from the axis of the rotary shaft 11, and the massage massage member 7 is centered on the axis of the rotary shaft 11. It swings so as to fall forward. As a result, as shown on the right side of FIG. 5, the massage massage member 7 swings so as to fall forward, and the massage treatment element 12 at the tip of the massage massage member 7 can be advanced further forward. Become.

  On the other hand, in the chair type massage machine which is in the state as shown on the right side of FIG. 5 (the state where it has advanced forward), the massage mechanism 5 is moved downward with respect to the base member 4 using the massage mechanism moving means described above. If it does so, force will act in the reverse direction to the above-mentioned case, and the massaging massage member 7 will rock | fluctuate so that it may rise toward the back centering on the shaft center of the rotating shaft 11. FIG. As a result, the massage mechanism 5 is in a state as shown on the left side of FIG. 5, and the massage treatment element 12 at the tip of the massage massage member 7 can be further retracted (retracted) backward.

By the way, the chair type massage machine of this invention detects the predetermined position of the up-down direction detected after detecting the predetermined position (for example, shoulder position) of the up-down direction corresponding to a user's treatment part by an up-down position detection means. The control unit (not shown) for moving the massage treatment element 12 and the grip treatment element 9 along the front-rear direction is provided.
This control unit outputs a signal to each of the above-described vertical movement mechanism 6, vertical position detection means, massage mechanism movement means, and front / rear movement mechanism, and the vertical position detection means in the vertical direction corresponding to the user's treatment section. The position is detected, and the vertical movement mechanism 6 and the forward / backward movement mechanism are alternately operated according to the detection result of the vertical position detection means.

Specifically, in this control unit, each mechanism is controlled according to the following first to third procedures.
The first procedure is to move the position of the base member 4 in the vertical direction inside the backrest using the vertical movement mechanism 6 described above. In this first procedure, the base member 4 is moved downward from above, and the base member 4 is moved while projecting forward so that the massaging treatment element 12 can contact the shoulder of the user.

Specifically, a command is sent to a drive unit or the like of the vertical movement mechanism 6 (not shown) to guide the base member 4 along the guide unit 3.
The second procedure is to determine that the massage mechanism 5 is at a location corresponding to the shoulder position of the user using the vertical position detection means.
For example, as shown in FIG. 4, when the base member 4 moves from the upper side to the lower side to the position where the massaging treatment element 12 comes into contact with the user's shoulder, the massaging treatment element 12 hits the shoulder and is pushed back to the back. The massaging member 7 swings around the axis of the rotating shaft 11 so as to get up backward.

Then, the joint arm 24 connected to the protruding piece 23 on the proximal end side of the massage massage member 7 converts the swing angle of the massage massage member 7 into a linear movement distance. The joint arm 24 moves downward.
Then, a force acts downward also on the massage mechanism 5 connected to the end of the joint arm 24 opposite to the side connected to the protruding piece 23, and the massage mechanism 5 guides the base member 4. It moves downward along the rail 29. As a result, the distance measuring unit 21 measures a change in the linear movement distance that is equal to or greater than a predetermined size, and the shoulder position of the user can be detected from the change in the linear movement distance.

In this way, when the vertical position detection means determines that “the massage mechanism 5 is in a place corresponding to the user's treatment part”, the vertical movement mechanism 6 is stopped and the position of the massage mechanism 5 is changed. Hold in shoulder position. Then, the massaging treatment element 12 and the grasping treatment element 9 are aligned in the front-rear direction by the third procedure described below.
In the third procedure, the massaging treatment element 12 and the gripping treatment element 9 are swung in the front-rear direction using the above-described back-and-forth movement mechanism, and the positions of the massaging treatment element 12 and the grasping treatment element 9 in the front-rear direction are treated. To match.

  That is, a command is sent to a massage mechanism moving means (not shown) to move the massage mechanism 5 upward with respect to the base member 4. Then, the massaging massage member 7 connected to the base member 4 via the joint arm 24 also tries to move upward. However, the rotation shaft 11 of the massage massage member 7 is fixed so as not to move with respect to the base member 4 by using the shaft support portion 30. Therefore, when the joint arm 24 moves upward, a force is applied to the protruding piece 23 of the massaging member 7 around the axis of the rotating shaft 11, and the massaging member 7 moves forward about the axis of the rotating shaft 11. It swings to fall down. As a result, as shown on the right side of FIG. 5, the massage treatment element 12 at the tip of the massage massage member 7 can be advanced further forward.

  When the massage treatment element 12 is moved backward, a command is sent to the massage mechanism moving means to move the massage mechanism 5 downward relative to the base member 4. Then, the massaging massage member 7 connected to the base member 4 via the joint arm 24 also tries to move downward. However, the rotation shaft 11 of the massage massage member 7 is fixed so as not to move with respect to the base member 4 by using the shaft support portion 30. Therefore, when the joint arm 24 moves downward, the massaging massage member 7 swings so as to rise rearward about the axis of the rotating shaft 11. As a result, as shown on the left side of FIG. 5, the massage treatment element 12 at the tip of the massage massage member 7 can be advanced further forward.

By the way, the method of changing the position of the treatment element in the front-rear direction described above ( that is, the method of operating the chair type massage machine) automatically moves the massage member 7 back and forth using the back-and-forth movement mechanism. The amount of actual movement of the base member 4 by sending a command to is set in advance as the amount of movement of the massage mechanism 5 relative to the base member 4.
For example, a rocking position along the forward direction or a rocking position along the backward direction of the massage massage member 7 is determined in advance, and the massage massage is rocked back and forth with a back-and-forth movement mechanism to a predetermined rocking position. By doing so, the massaging massage member 7 can be automatically aligned with the treatment part. If it does in this way, the position of the massage treatment element 12 and the grip treatment element 9 can be aligned with the treatment part in the front-rear direction without bothering the user.

However, the front-rear position adjustment of the massaging treatment element 12 and the gripping treatment element 9 can also be performed manually.
That is, after detecting the vertical position corresponding to the shoulder position of the user by the vertical position detection means, the massage treatment element 12 and the grip treatment element 9 are manually moved along the front-rear direction based on the detected vertical position. Moving. That is, the movement position of the massaging massage member 7 along the front-rear direction is determined in advance, and when the user selects a certain movement position, the massaging massage is swung back and forth by the front-rear movement mechanism up to that movement position. The massaging member 7 is manually aligned with the treatment part.

The reason why it is necessary to adjust the front and rear positions of the massaging treatment element 12 and the gripping treatment element 9 is as follows.
For example, even when the massage treatment element 12 or the grip treatment element 9 is generally set to a position (so-called predetermined position) where the pressure of the treatment element is best (so-called predetermined position), depending on the user, depending on the user, There is a case where the treatment part is desired to be massaged strongly by bringing the treatment part closer to the treatment part. Further, even when the massage treatment element 12 or the grip treatment element 9 is set to a predetermined position, depending on the user, the treatment element is moved away from the predetermined position (moved backward) to give a feeling of massage to the treatment part. You may want to make it weaker. In such a case, it is preferable to align the treatment part automatically or manually using a back-and-forth movement mechanism.

By the way, you may make it perform the position change method of the front-back direction of a treatment element (The massage treatment element 12 or the grip treatment element 9) by the combination of an automatic and manual.
That is, after the vertical position detection means detects the vertical position corresponding to the shoulder position of the user, the massage treatment element 12 and the grip treatment element 9 are automatically moved to a predetermined position in the front-rear direction based on the detected vertical position. Then, the massaging treatment element 12 and the grasping treatment element 9 may be manually moved forward or backward from a predetermined position.

Here, as the “predetermined position”, an intermediate position in the front-rear direction is selected, and the treatment element is automatically moved to this intermediate position, and then the massage treatment element 12 and the grabbing treatment element 9 are manually operated using the front-rear movement mechanism. May be further protruded forward or retracted backward. Even in this case, it is possible to change the pushing condition of the treatment element according to the preference of the user.
When manually moving the massaging treatment element 12 or the grabbing treatment element 9 back and forth using the back-and-forth movement mechanism, buttons such as “strong”, “medium”, and “weak” are provided in advance on the operation panel or the like. In addition, the user adjusts the position of the massage treatment element 12 and the grabbing treatment element 9 back and forth by pressing each button according to his / her preference. In other words, the massage feeling by the treatment element is selected according to the user's preference. It is good to constitute so that.

If it does in this way, the position of the massage treatment element 12 or the grip treatment element 9 can be surely aligned at a position according to the user's preference, and the treatment part can be accurately grasped and massaged. Is possible.
The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. In particular, in the embodiment disclosed this time, matters that are not explicitly disclosed, for example, operating conditions and operating conditions, various parameters, dimensions, weights, volumes, and the like of a component deviate from a range that a person skilled in the art normally performs. Instead, values that can be easily assumed by those skilled in the art are employed.
