Description

  The present invention relates to a massage device that operates so that a treatment element that contacts a treatment site massages the treatment site, and a chair-type massage machine using the massage device.

  As this type of massage device, a device having a disc shape and a kneading ball (treatment element) that makes an outer peripheral surface contact a treatment site is generally known. In this massage device, a treatment site is massaged or hit, a pressure stimulus such as acupressure is applied to the treatment site, and further, as shown in FIG. 8 (a), itching applied to the treatment site. The ball 27 can be reciprocated along the treatment site in the X direction in the figure to perform a rolling massage that gives stimulation over a wide range of the treatment site.

  In addition, this massage device has different contact pressures of the kneading balls 27 to the treatment site immediately after the start of treatment where the muscles of the treatment site are not loosened in order to make the stimulation to the treatment site smaller than other periods. There is also a function of making it smaller than the period (see, for example, Patent Document 1).

  On the other hand, as a massage device having another structure, there is a device that includes a spherical pressing sphere (treatment element) that presses a treatment site and continuously moves the pressing sphere with respect to the treatment site. This massage device includes a turntable that is disk-shaped and rotates around a fixed axis, and a pressing sphere is disposed in an annular recess formed on one surface in the thickness direction of the turntable so as to surround the center. The massage device is housed in a case having a substantially circular opening that exposes the surface of the turntable on which the annular recess is formed, and the turntable and the pressing sphere are covered by a cloth cover provided in the opening. .

In this configuration, the rotation of the turntable causes the pressing sphere to rotate within the annular recess, and by pressing the pressing sphere against the treatment site so as to sandwich the pressure sphere between the treatment site and the turntable, the cover and A frictional force is generated between the pressing sphere and the pressing sphere rolls, and the position of the pressing sphere with respect to the treatment site continuously moves. As a result, the pressing sphere contacts the treatment site in a point-like manner to give a pressure stimulus such as finger pressure, and the stimulus can be given to the entire region of the treatment site facing the annular recess ( For example, see Patent Document 2).

  By the way, in the massage by a masseur, generally, a treatment method called light rubbing is frequently used. As shown in FIG. 8 (b), the light rubbing is a grinding operation in which the hand is moved so as to draw an arc Z while the treatment site is stroked by hand (the hand is swung in the direction of Y in the figure). This is a procedure performed to acclimate the body to massage stimulation. In particular, it is generally known that light rubbing called palm palm rubbing by the palm is generally performed in the vicinity of the flank of the human body, and the sensory effect is high.

  However, in the conventional massage device, as described above, the treatment site is squeezed or struck, a pressure stimulus such as acupressure is applied to the treatment site, or the kneading balls 27 pressed against the treatment site are moved. There was only a thing that gave a rolling massage, and there was no idea to realize a rubbing motion like a light rub with a massage device.

  Therefore, an object of the present invention is to provide a massage device capable of light rubbing and a chair type massage machine using the massage device.

  According to the first aspect of the present invention, the treatment element that contacts the treatment site of the human body in a planar shape, the rotation drive unit that rotates the drive shaft, and the drive shaft and the treatment element are interposed between the treatment shaft and the treatment shaft by rotation. And a power transmission unit that revolves the treatment element around the drive shaft and restricts the rotation of the treatment element to convert the rotation operation of the drive shaft into the grinding operation of the treatment element.

  According to this configuration, the treatment element is rubbed against the treatment site by the rotation drive unit rotating the drive shaft, and it is possible to treat the treatment site with light rubbing. . That is, it is possible to realize light rubbing by the massage device. Since light rubbing only rubs the treated area and not a painful stimulus, this massage device can be used without feeling pain even immediately after the start of treatment when the muscles of the treated area are not loosened. It can also be used by people who have pain near the treatment site.

  According to a second aspect of the present invention, in the first aspect of the present invention, the power transmission unit includes a first joint body fixed at a fixed position, and an axial direction of the drive shaft with respect to the first joint body. A second joint body that is arranged in parallel and to which the treatment element is attached, and is interposed between the first and second joint bodies, and slides in directions intersecting each other with respect to each of the first and second joint bodies. A floating cam that constitutes an Oldham joint together with the first and second joint bodies by being movably engaged to restrict the rotation of the treatment element, an eccentric wheel that rotates with the drive shaft, and a drive shaft that is spaced apart from the drive shaft. And an eccentric shaft that revolves around the drive shaft by being pivotally supported by the second joint main body and the eccentric ring so that the second joint main body and the eccentric ring are rotationally coupled with each other. And

  According to this configuration, since the rotation operation of the rotation drive unit can be converted into the grinding operation of the treatment element only by the Oldham coupling, the eccentric ring, and the eccentric shaft, it is possible to lightly rub with a relatively small number of parts. A massage device can be realized.

  The invention of claim 3 is characterized in that, in the invention of claim 1 or 2, the treatment element is formed in the shape of a palm of a human body.

  According to this configuration, treatment by the palm of the human body can be reproduced by the treatment element, so that treatment close to light rubbing by the palm of the human body is possible.

  The invention of claim 4 is characterized in that, in the invention of claim 3, the treatment element is formed by coating a rigid bone member with a covering material having rubber elasticity.

  In this configuration, the treatment element imitates the feeling of the palm of the human body, and treatment close to treatment by a masseur is possible.

  The invention of claim 5 is a chair-type massage machine using the massage device according to any one of claims 1 to 4, wherein the treatment element performs a rubbing operation along a back part of a human body. As described above, the massage device is disposed on the backrest part, the depth drive part that moves the treatment element in the thickness direction of the backrest part, the left and right drive part that moves the treatment element in the width direction of the backrest part, and the height of the backrest part A vertical drive unit that moves the treatment element in the direction, an operation unit that is operated to set the operations of the depth drive unit, the left and right drive unit, and the vertical drive unit, and the depth drive unit and the left and right by the operation of the operation unit It has a control part which operates each of a drive part and an up-and-down drive part, and a control part has a treatment element control function which operates the rotation drive part by operation of an operation part.

  According to this configuration, the user can adjust the treatment site by operating the operation unit, and can adjust the grinding operation of the treatment element.

  In the present invention, the treatment element is rubbed against the treatment site by the rotation drive unit rotating the drive shaft, and the treatment site can be lightly rubbed. That is, it is possible to realize light rubbing by the massage device. Since light rubbing only rubs the treated area and not a painful stimulus, this massage device can be used without feeling pain even immediately after the start of treatment when the muscles of the treated area are not loosened. In addition, there is an advantage that even a person having pain in the vicinity of the treatment site can be used.

  As shown in FIG. 1, the massage device 1 according to the present embodiment includes a treatment element 2 that comes into contact with a treatment site of a human body, a rotation drive unit 3 including a geared motor that rotates a drive shaft 30, and a drive shaft. 30 and the power transmission part 4 interposed between the treatment elements 2.

  The power transmission unit 4 receives the rotation of the drive shaft 30 and causes the treatment element 2 to revolve around the drive shaft 30 to move the treatment element 2 in contact with the treatment area along the treatment area along the treatment area. In addition, the rotation of the treatment element 2 caused by the revolving motion is restricted, and as a result, the rotation operation of the drive shaft 30 is converted into the grinding operation of the treatment element 2. That is, the treatment element 2 gives the same stimulation as the light rubbing, which is a grinding operation by the palm of the human body, to the treatment site.

  Specifically, the power transmission unit 4 includes an eccentric wheel 5 that rotates together with the drive shaft 30, and an eccentric shaft 6 that is substantially parallel to the drive shaft 30 and disposed away from the drive shaft 30. The treatment element 2 is fixed with respect to the shaft 6 and the eccentric shaft 6 is eccentrically rotated with respect to the drive shaft 30 to cause the treatment element 2 to revolve around the drive shaft 30. The eccentric wheel 5 has a disk shape centered on the drive shaft 30 and is formed in a shape in which a cylindrical bearing protrusion 50 protrudes from the center of the surface facing the rotation drive unit 3 toward the rotation drive unit 3. Is done. A drive bearing hole 51 having an inner diameter substantially equal to the outer diameter of the drive shaft 30 is formed in the central portion of the front end surface of the bearing protrusion 50, and the eccentric ring 5 is inserted into the drive bearing hole 51 to drive the drive shaft 30. Rotate with 30. An eccentric bearing hole 52 for rotatably supporting the eccentric shaft 6 is formed on the surface of the eccentric wheel 5 opposite to the surface from which the bearing protrusion 50 protrudes, at a position closer to the upper side than the center portion.

  The end of the eccentric shaft 6 opposite to the end supported by the eccentric ring 5 is fixed to a rectangular plate-shaped mounting plate 7 (second joint body) whose plate surface is substantially orthogonal to the eccentric shaft 6. Is done. When the treatment element 2 is fixed to the eccentric shaft 6 by attaching the treatment element 2 to the plate surface of the mounting plate 7 opposite to the eccentric ring 5, it is driven by the rotation of the drive shaft 30 as described above. The treatment element 2 revolves around the shaft 30. In this embodiment, the eccentric shaft 6 is fixed to the mounting plate 7 and is rotatable with respect to the eccentric wheel 5. However, the eccentric wheel 5 and the mounting plate 7 are rotatable with respect to the eccentric shaft 6. In other words, it is sufficient that the eccentric shaft 6 is rotatable with respect to either the eccentric ring 5 or the mounting plate 7.

  With the above-described configuration alone, the revolving motion of the treatment element 2 is accompanied by rotation. Therefore, even though the treatment element 2 that is in planar contact with the treatment site can be moved along the treatment site, 2 does not lead to the same stimulation as the light rubbing which is a grinding operation by the palm of the human body. Therefore, the power transmission unit 4 of the present embodiment includes an Oldham joint having the mounting plate 7 as the second joint body 7, and restricts the rotation of the treatment element 2 by restricting the direction of the treatment element 2 in one direction. .

  Specifically, the second joint body 7 includes a first joint body 8, a first joint body 8, and a second joint disposed between the second joint body 7 and the rotation driving unit 3. An Oldham joint is formed with the floating cam 9 interposed between the joint bodies 7. In the present embodiment, the first joint body 8 is formed in a disk shape centered on the drive shaft 30, and the floating cam 9 is in the shape of a disk centered on the drive shaft 30 like the first joint body 8. The outer shape of the first joint body 8 is smaller.

  The floating cam 9 has first protrusions 91 that protrude from the surface facing the first joint body 8 toward the first joint body 8 at both ends in the vertical direction (hereinafter referred to as the vertical direction) in the figure. In the first joint body 8, the first protrusions 91 are engaged with the concave and convex portions and the first concave portions 81 whose longitudinal dimensions are larger than the first protrusions 91 are respectively formed at portions facing the front end surfaces of the first protrusions 91. Is done. The first protrusion 91 can move only in the vertical direction in the first recess 81, and as a result, the floating cam 9 is engaged with the first joint body 8 so as to be slidable only in the vertical direction. To do.

  Furthermore, the floating cam 9 has both ends in a direction (hereinafter referred to as a lateral direction) in which the second protrusion 92 that protrudes from the facing surface of the second joint body 7 toward the second joint body 7 is substantially perpendicular to the longitudinal direction. Have in part. In the second joint body 7, the second protrusions 92 are engaged with the concave and convex portions, and the second concave portions 70 whose lateral dimensions are larger than the second protrusions 92 are respectively formed at portions facing the tip surfaces of the respective second protrusions 92. Is done. Here, in this embodiment, since the thickness dimension of the 2nd coupling main body 7 is small, let the 2nd recessed part 70 be the notch which penetrates in the thickness direction. The second protrusion 92 can move only in the lateral direction in the second recess 70, and as a result, the second joint body 7 engages with the floating cam 9 so as to be slidable only in the lateral direction. To do.

  Therefore, between the first and second joint bodies 7, 8, the second joint body 7 maintains the relative orientation with respect to the first joint body 8 in one direction, and the first joint body 8 can slide in both the vertical direction and the horizontal direction. In the present embodiment, the floating cam 9 has a protrusion and the first and second joint bodies 7 and 8 are formed with the recesses. However, the first and second joint bodies 7 and 8 A configuration in which each has a protrusion and a recess is formed in the floating cam 9 may be employed.

  By the way, in order to restrict the rotation of the second joint body 7 by restricting the relative orientation of the second joint body 7 with respect to the first joint body 8 in one direction, the first joint body 8 is fixed. Fixed in position. Further, the first joint body 8 has a function as a bearing for the eccentric ring 5 by penetrating a bearing hole 80 into which the eccentric ring 5 is rotatably inserted in the center of the first joint body 8. . A through hole 90 having a diameter substantially equal to that of the bearing hole 80 is formed through the center of the floating cam 9, and the floating cam 9 is prevented from obstructing the movement of the eccentric shaft 6 by passing the eccentric shaft 6 through the through hole 90. To do.

  In the above-described configuration, if the drive shaft 30 rotates, the treatment element 2 revolves around the drive shaft 30 and the rotation of the treatment element 2 is restricted. The child 2 can be rubbed along the treatment site, and light massage treatment by the massage device 1 is realized. The power transmission unit 4 is not limited to the mechanism exemplified in the present embodiment, and may be any mechanism that can convert the rotation operation of the drive shaft 30 into the grinding operation of the treatment element 2.
