Description

  The present invention relates to a massage device that performs a massage operation similar to that performed by a human technique.

  2. Description of the Related Art Conventionally, there is known a massager that massages a user's treatment site by compressing / relaxing the expansion / contraction of an air bag. Among them, for example, there is also known a massage machine that increases the compressive force of the air bag by using a plurality of air bags in piles. This involves stacking a plurality of air bags in the inflating direction and connecting adjacent air bags with a connecting means having a ventilation path communicating with each other.

  However, by stacking a plurality of air bags, the pressure force of the air bags is increased, but only by pressing a specific portion, the operation of moving the air bag along the treatment target portion in the pressed state does not occur. Therefore, it was not possible to achieve the same kneading method as the linear kneading that is performed as a typical massage technique. In addition, the linear kneading is a technique of linearly moving the acupressure part with respect to the muscle fibers in a state where pressure is applied to the treated part with the acupressure part (for example, the thumb or the palm) to loosen the stiffness. is there.

  Therefore, the inventors have proposed in Japanese Patent Application No. 2014-167038 (Patent Document 1) a massage machine that can realize the same kneading method as the linear kneading. This has a pair of upper and lower massage airbags and an air injecting and discharging portion connected to the upper airbag. Then, a connecting portion having a vent hole for communicating these airbags with each other is provided at a portion where the pair of airbags overlap. Further, a fixing portion for rotatably fixing the upper airbag to the base is provided. In this, a linear kneading is realized by rotating the inflated upper airbag around the fixed portion while the lower airbag inflates.

  Further, in Patent Document 2, a part of a pair of second airbags that press the scapula is overlapped with a first airbag that presses the spine, and after inflating the pair of second airbags, the first air bag is inflated. What inflates the bag is described. With this, the ribs are opened.

Japanese Patent Application No. 2014-167038 JP-A-2005-198742

  However, in the massage machines of Patent Document 1 and Patent Document 2, the airbag (treatment element) is limited to rotate in one direction around one end fixed to the base.

  Therefore, there is a demand for a massage device that can change not only the linear kneading from one direction but also the opposite direction by changing the rotation direction of the airbag, as in the case of a massage technique. It was

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a massage device that realizes linear kneading that reciprocates from one direction and from the opposite direction, similar to a procedure.

  In order to solve the above-mentioned problems, a structural feature of the invention according to claim 1 is that in a massage device, a base portion having a base surface and a thin plate surface which is not expandable and contractible and can be deformed flexibly. A sheet-like member disposed to face the sheet-like member at a predetermined distance from each other, a pressing airbag that is provided on the upper surface of the sheet-like member so as to be tiltable with respect to the sheet-like member, and expands and contracts, the base portion and the sheet-like member. A first supporting airbag which is provided adjacent to one side of the pressing airbag between a member and expands and contracts, and the pressing airbag other than the base portion and the planar member. A second supporting airbag which is provided adjacent to the side and expands and contracts, and one end of which is connected to a first lateral portion of the pressing airbag on the first supporting bag side, Second side of the second support airbag side A first traction member, the other end of which is connected to the base portion at a position facing the portion, and one end of which is connected to the second side portion on the second support bag side of the pressing airbag, A second traction member, the other end of which is connected to the base portion at a position facing the first side portion on the side of the first support airbag of the pressing airbag, and the planar member, and A first guide member for guiding a first towing member on the side of the first supporting airbag; and a second guide member provided on the planar member for guiding the second towing member on the side of the second supporting airbag. Expanding and contracting by supplying compressed air to the skin member fixed to the base portion to cover the upper surface of the pressing airbag, the pressing airbag, the first supporting airbag and the second supporting airbag. Expansion and contraction device for The device is operated to alternately inflate and deflate the first support airbag and the second support airbag, and the pressing air is associated with the inflation of the first support airbag and the second support airbag. And a control device for inflating the bag.

According to this, the massage device tilts the pressing airbag toward the first supporting airbag side or the second supporting airbag side by alternately inflating and contracting the first and second supporting airbags. During the expansion, the tilting of the pressing airbag is increased by the first towing member or the second towing member. Then, the pressing airbag is inflated in a state where the pressing airbag is tilted to either direction.
In this way, the massage device can tilt the pressing airbag toward the first supporting airbag side or the second supporting airbag side to further inflate the pressing airbag. Therefore, with the pressing airbag, the user's treatment site can be linearly kneaded and unraveled in both directions in a state where pressure is applied like linear kneading.

At the same time, the fourth ventilation cutoff valve 14b is closed to discharge air from the left side support airbag 6l. When it is determined that the air pressure P2 of the pressing airbag 4 and the fulcrum airbag 40 is equal to or higher than the predetermined pressure PC, the control device 8 returns to S114 and executes the program.

  Next, the control device 8 shifts the program to S117 and determines whether the air pressure P3 of the left side support airbag 6l is less than the predetermined pressure PD. When the air pressure P3 of the left side support airbag 6l is less than the predetermined pressure PD, the control device 8 determines that all the airbags have returned to the initial state of contraction (see FIG. 4). When it is determined that the air pressure P3 of the left side support airbag 6l is equal to or higher than the predetermined pressure PD, the control device 8 returns to S116 and executes the program.

  Next, the control device 8 shifts to the program S118, and determines whether or not the elapsed time T during which the massage device 1 has driven a predetermined operation is equal to or longer than the set duration time TA.

  When determining that the elapsed time T is equal to or longer than the set duration TA, the control device 8 stops the operation of the massage device 1 such as the air pump 17 and ends the control.

  When determining that the elapsed time T is less than the set duration TA, the control device 8 returns to S102 and repeats the control for driving the massage device 1.

  As is clear from the above description, in the massage device 1 of the first embodiment, the base portion 21 having the base surface 21a and the thin plate surface shape that is not expandable and contractible and is deformable flexibly at a predetermined distance from the base portion 21.

Support airbag 5 and left support The expansion / contraction device 7 for supplying compressed air to the airbag 6l to inflate and contract, and the expansion / contraction device 7 are operated to alternately inflate and contract the central support airbag 5 and the left support airbag 6l, and at the same time, the central support air And a control device 8 for inflating the pressing airbag 4 in association with the inflation of the bag 5 and the left side supporting airbag 6l.

  According to this, by supplying compressed air to the central supporting airbag (first supporting airbag) 5, the central supporting airbag is inflated. At this time, since the left side supporting airbag 6l (the left and right supporting airbags 6 and the second supporting airbag) is in a contracted state, the planar member 3 on the side of the central supporting airbag 5 is separated from the base portion 21, and the left side supporting airbag 6l is supported. The planar member 3 on the side of the airbag 6l is maintained in a state where it is not separated from the base portion 21. As a result, the pressing airbag 4 arranged on the planar member 3 tilts with the center support airbag 5 side being more distant from the base portion 21 than the left support airbag 6l side.

  When the central support airbag 5 side of the planar member 3 is separated from the base portion 21, the other end portion 42b connected to the base portion 21 of the second traction member 42 is separated from the planar member 3. As a result, the second pulling member 42 having the one end portion 42a connected to the second side portion 4b of the pressing airbag 4 is pulled. Therefore, the pressing airbag 4 laterally moves or tilts toward the left side supporting airbag 6l by the amount pulled by the second towing member 42.

  Next, in connection with the inflation of the central support airbag 5, the inflation and deflation device inflates the pushing airbag 4 by supplying compressed air to the pushing airbag 4 after the inflation of the central supporting airbag 5. Let The pressing airbag 4 is in a state in which the second lateral portion 4b is pulled, and therefore is expanded around the end portion of the second guide member 44, which is guided by the second pulling member 42, on the left side support airbag 6l side. While rotating, it turns to the left side support airbag 6l side.
