BACKGROUND OF THE INVENTION
The present invention relates to a massage mechanism of a massage machine that treats the body of a user.
[0002]
[Prior art]
A massage machine such as a chair type or a mattress type is widely known. For example, a chair-type massage machine has a seat portion and a backrest portion, and has a structure in which a treatment element for performing treatment of the human body is provided in the backrest portion, and drives a plurality of built-in electric motors In general, it is possible to cause the treatment element to selectively perform the kneading operation, the tapping operation, the treatment site change, and the like.
[0003]
More specifically, the massage machine generally includes a treatment unit having a pair of treatment elements arranged side by side in the height direction of the user in order to stimulate the body of the user in the height direction of the user. They are arranged side by side in the vertical direction. And these treatment parts perform the massage operation | movement of a to-be-treated person's body by approaching and separating from each other in a substantially parallel direction.
[0004]
[Problems to be solved by the invention]
When the user's body, such as a shoulder, is grabbed by a human hand, the user's body is often squeezed so as to grasp the body in the height direction (so-called grabbing). However, there is a problem that conventional massage machines cannot perform such a gripping operation and cannot provide a stimulus that can sufficiently satisfy the user.
[0005]
The present invention has been made in view of the above problems, and by grasping and grasping the body of the user by moving the pair of treatment elements close to and away from each other in the substantial height direction of the user. An object is to provide a massage machine that can be used.
[0006]
[Means for Solving the Problems]
  In order to solve the above-described problems, the present invention provides a pair of treatment elements that are arranged in parallel in a substantial height direction of the body of the user and that stimulates the body of the user, and the pair of treatment elements is treated. Gripping operation mechanism for bringing a person close to and away from each other in an approximate height direction of the person, a driving machine having a rotating shaft, and the rotating shaftIn a state inclined at a predetermined angle to the end ofAn inclined portion attached to the gripping operation mechanism, and moving the gripping operation mechanism through the inclined portion by rotating the rotation shaft, thereby moving the pair of treatment elements to the left and right And a moving part that moves so as to draw a substantially ellipse in the vertical direction.The gripping mechanism is provided on a driven shaft that can rotate around an axis and the driven shaft, and is eccentric in different directions so as to revolve around the axis of the driven shaft. The pair of annular eccentric portions and the base end portions are attached to the outer circumferences of the pair of eccentric portions via bearings, respectively, and the pair of treatment elements are attached to the distal ends. A pair of arms, and a transmission unit that transmits the rotation of the rotary shaft to the driven shaft.To do.
[0007]
  According to this configuration, the pair of treatment elements can approach and separate the treatment person's body by approaching and separating from each other in the substantial height direction of the treatment person.Further, since the gripping operation mechanism is attached to the moving unit, the gripping operation mechanism is moved by the moving unit.
[0009]
  Also thisAccording to the configuration, the eccentric portion revolves with respect to the axis of the driven shaft by rotating the driven shaft. Further, since these eccentric portions are eccentric in different directions from the axis of the driven shaft, a phase difference occurs in the revolution period of these eccentric portions. Thereby, the pair of treatment elements repeats approaching and separating from each other in the height direction of the user. More specifically, when one treatment element out of the pair of treatment elements rises in the substantially height direction of the user, the other treatment elements descend. Conversely, when one treatment element descends, the other treatment element rises. By repeating these operations, the body of the user can be grabbed. In particular, when the eccentric portions are eccentric to the opposite sides with respect to the axis of the driven shaft, the phase difference is approximately 180 °. As a result, the difference between the distance between each treatment element when the pair of treatment elements are closest to each other and the distance between each treatment element when the pair of treatment elements are farthest compared to the case of other phase differences Become bigger.
  That is, the amount by which the pair of treatment elements grasps the body of the user can be increased.
Thereby, a more effective stimulus can be given to a user's body.
  Furthermore, according to this configuration, since the gripping operation mechanism includes the transmission unit that transmits the rotation of the rotation shaft of the moving unit to the driven shaft, the pair of treatment elements are moved as described above, and are moved closer to and away from each other. be able to.
  The transmission unit may include a switching unit that switches between a state in which the rotation of the rotation shaft is transmitted to the driven shaft and a state in which the rotation is not transmitted. Thus, in the massage machine according to the present invention, the moving unit performs only the normal squeezing operation performed by moving the squeezing operation mechanism according to the preference of the user, or the squeezing operation by the squeezing operation mechanism. Can be combined. In addition, as said transmission part, an electromagnetic clutch can be used, for example.
Furthermore, in the present invention, the eccentric portion may be configured to be eccentric to substantially opposite sides with respect to the axis of the driven shaft.
[0010]
  In the present invention,A pair of left and right gripping operation mechanisms and a pair of left and right moving units are provided, and each of the gripping operation mechanisms operates by displacing the inclined portions of the moving units so as to draw a conical locus. The left and right treatment elements move so as to approach and separateIt may be configured.

The small diameter portion 17b is loosely fitted. Thereby, the inclined portion 17 is rotatable with respect to the first pulley 61. With the above configuration, when the electromagnetic clutch 50 is closed, the first pulley 61 also rotates together with the transmission unit 50b. On the other hand, when the electromagnetic clutch 50 is open, only the small diameter portion 17b rotates and the transmission portion 50b and the first pulley 61 are not rotated.
[0043]
Further, the first pulley 61 is connected to the second pulley 64 via a belt-like belt 63. A fitting hole 64a penetrating in the axial direction is provided at the center of the second pulley 64, and the driven shaft 70 is fitted into the fitting hole 64a. Thereby, the rotation of the second pulley 64 can be transmitted to the driven shaft 70.

[0048]
Next, the operation of the gripping operation mechanism 14 will be described in detail with reference to FIGS. FIG. 8 is an arrow view of the treatment element 10 and the like seen from the arrows AA shown in FIG. FIG. 9 is a side view of the treatment element 10 and the arm 13 shown in FIG. The arrows in the figure indicate the locus of the central portion of the treatment element 10.
[0049]
As described above, when the electromagnetic clutch 50 is closed, the eccentric part 72 revolves around the axis of the round bar part 71 b, so that the arm 13 loosely fitted to the eccentric part 72 also revolves together with the eccentric part 72. Further, since the movement amount of the extending portion 13 b of the arm 13 is regulated by the movement amount regulating member 80, the extending portion 13 b of both arms 13 has a substantially constant distance between the connection points with the movement amount regulating member 80. Move while keeping. As a result, the two arms 13 move so as to approach and separate from each other due to the revolution of the eccentric portion 72, and as a result of this movement, both arms 13 move to the axial center of the eccentric portion 72 as indicated by the arrows in FIG. Swing up and down with fulcrum as the fulcrum. Therefore, the operation of the arm 13 is a combination of the above revolution and swing. Further, since the phase difference between the revolution periods of the two eccentric portions 72 is approximately 180 °, the phase difference between the revolution period and the swing period of both arms 13 is also approximately 180 °. As a result, both arms 13 approach and separate from each other. Thereby, the treatment element 10 can perform what is called a gripping operation.
[0050]
Further, the swing angle of each arm 13 in this case is determined by the distance L1 from the axial center of the eccentric portion 72 of each arm 13 to the connection portion between the extended portion 13b of each arm 13 and the movement amount regulating member 80. Therefore, by adjusting (shortening or lengthening) the distance L1, it is possible to adjust (increase / decrease) the amount of movement of the treatment element 10 attached to the tip of each arm 13. Thereby, the amount by which the pair of treatment elements 10 grasps the body of the user can be adjusted as appropriate.
[0051]
Here, in order to clarify the operation of the pair of treatment elements 10, the operation of the treatment element 10 when the grasping movement mechanism 14 does not move has been described, but actually, the grasping movement mechanism 14 itself is a substantially ellipsoidal three-dimensional shape. Moving with a typical trajectory. Therefore, the operation of the treatment element 10 is combined with these operations.
[0052]
Further, in the massage machine 1 according to the present embodiment of the present invention, the driven shaft 70 is opened from the rotary shaft 16 via the first pulley 61 and the second pulley 64 by opening and closing the electromagnetic clutch 50 shown in FIG. It is possible to control the rotational motion transmitted to the. Specifically, a signal is transmitted from the controller 203 shown in FIG. 7 to the electromagnetic clutch 50 to open / close the electromagnetic clutch 50. When the electromagnetic clutch 50 is closed as shown in FIG. 9, the rotation of the rotating shaft 16 is transmitted to the driven shaft 70 as described above, and the pair of treatment elements 10 approach and separate from each other (grabbing and gripping operation). ). On the other hand, when the electromagnetic clutch 50 is in the open state, the rotation of the rotary shaft 16 is not transmitted to the driven shaft 70, so the distance between the pair of treatment elements 10 is kept constant, and the gripping motion mechanism is driven by the rotation of the rotary shaft 16. Only 14 moves (normal stagnation operation). Thereby, only a normal squeezing motion can be performed according to the user's preference, and a normal squeezing motion and a grip squeezing motion can be combined.
[0053]
Moreover, in the massage machine 1 which concerns on this Embodiment of this invention, the pressure detector 202 shown in FIG. 7 detects the pressure with which a pair of treatment element 10 presses a user's body, Based on this detection result The controller 203 can also adjust the rotation speed of the motor 11. Thereby, the rotational speed of the rotating shaft 16 and the driven shaft 70 connected to the motor 11 can be adjusted. As a result, the moving speed of the gripping operation mechanism 14 and the speed at which the pair of treatment elements 10 approach and separate from each other can be adjusted. As the motor 11, a drive machine that controls the rotation speed such as an inverter motor can be used.
[0054]
Further, in the massage machine 1 according to the present embodiment of the present invention, the rotation phase angle detector 200 of the rotation shaft 16 and the rotation phase angle detector 201 of the driven shaft 70 are the rotation phases of the rotation shaft 16 and the driven shaft 70. Each angle is detected, and the controller 203 controls the timing for opening and closing the electromagnetic clutch 50 based on the detection result. Thereby, the phase of the rotating shaft 16 and the phase of the driven shaft 70 are synchronized. As a result, when the normal squeezing operation and the grasping squeezing operation are performed simultaneously, the operation timings of both the operations can always be matched, and the stimulus given to the user is stabilized without changing each time.
[0055]
