DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
FIG. 1 shows a massage chair 10 of the present embodiment. The massage chair 10 is assembled to a rear end of a seat surface 12 supported by a pair of left and right support legs 11 so that a backrest portion 13 can be tilted by a rotation shaft in the width direction. The ottoman 14 is assembled so as to be tiltable about a rotation shaft in the same direction. On both sides of the seating surface 12, armrest portions 15 extending in the front-rear direction are assembled.

  A cover piece 16 is assembled to the front end of the armrest portion 15 so as to be tiltable by a rotation shaft in the width direction. That is, the cover piece 16 is provided so that the rear end free end side thereof is expanded from the upper surface 15a of the armrest portion 15 at a predetermined angle, and the user's forearm portion A (see FIGS. 2 and 3; from the arm elbow). The hand side portion can be inserted between the armrest portion 15 and the armrest portion 15. An air bag 17 is installed on the upper surface 15a of the armrest portion 15 facing the cover piece 16, and two acupoint pressing projections 18 and 19 are armrested on the lower surface 16a of the cover piece 16 facing the upper surface 15a of the armrest portion 15. The cover piece 16 is integrally provided so as to protrude toward the portion 15 side. In this case, the cover piece 16 is a resin molded product, and the acupuncture pressing protrusions 18 and 19 are integrally formed with the molding.

  As shown in FIG. 2, the acupoint pressing protrusions 18 and 19 are used to treat the user's forearm portion A inserted between the armrest portion 15 and the cover piece 16 with the air bag 17 that expands and contracts. As shown in FIG. 3, it is provided so as to independently stimulate Tesato Risato and Kakuike, which are the points of the user's forearm A. The acupoint pressing projections 18 and 19 have rectangular pressing surfaces 18a and 19a for pressing Tesatori and Kaikeike, respectively, and the width direction length which is the longitudinal direction of the pressing surfaces 18a and 19a is long. The length of the cover piece 16 is approximately the same as the length in the width direction, and the cover piece 16 is formed with a sufficiently large area to press the Tesatori and the pond.

  The air bag 17 installed on the upper surface 15 a of the armrest portion 15 is connected to the distal end of a connection hose 20 as a flexible pipe line, and the base end of the connection hose 20 is located below the seat surface 12. It is routed toward the drive device 21 installed between the support legs 11.

  The drive device 21 includes an air pump 22 that is electrically driven based on a supply of household commercial power, and a plurality of electromagnetic valves 23 (only one is shown in FIG. 1) connected to the air pump 22. . A base end of a connection hose 20 extending from the air bag 17 on the armrest portion 15 side is connected to the discharge side connection portion 23 a of the electromagnetic valve 23.

  When the compressed air is generated by driving the air pump 22 and the electromagnetic valve 23 is switched from the atmosphere opening side to the supply side, the compressed air from the air pump 22 expands the air bag 17 through the connection hose 20. At this time, the user's forearm portion A, which is pushed upward (in the cover piece 16 side) with the expansion of the air bag 17, is pressed against the projections 18 and 19 for pressing points. On the other hand, when the predetermined inflating operation of the air bag 17 is completed, the solenoid valve 23 is switched from the supply side to the atmosphere opening side, the air in the air bag 17 is released to the atmosphere, and the air bag 17 is contracted. During the treatment, this expansion / contraction operation is repeated.

  Thus, in the state where the user's forearm portion A is inserted between the armrest portion 15 and the cover piece 16 (in this case, the palm is disposed toward the upper surface 15a of the armrest portion 15), 19 presses an acupuncture point on the upper surface of the forearm portion A such as Tesatori or Kyukaike, and after a predetermined press, the air in the air bag 17 is removed and contracted, and released from the pressed state. In this way, the forearm A is subjected to treatment such as itchiness or compression based on pressing from above and below.

  Incidentally, in this massage chair 10, a pair of air bags 24 for the buttock are installed on both sides of the seat surface 12, and a pair of air bags 25 for the lumbar region are installed on both lower sides of the backrest 13. 14, a plurality of air bags 26 for calves are installed. Each air bag 24 to 26 is inflated and contracted by the operation of the air pump 22 and a solenoid valve (not shown) corresponding to each air bag 24 to 26, and air treatment is also performed on each treatment site such as the buttocks, the waist, and the calf. To be done.

Next, characteristic effects of the present embodiment will be described.
(1) The air bag 17 is provided on the upper surface 15a of the armrest portion 15, and the acupoint pressing projections 18 and 19 for pressing the user's arm are integrally provided on the lower surface 16a of the cover piece 16 so as to expand and contract. The air bag 17 and the acupoint pressing protrusions 18 and 19 perform treatment to press the user's forearm A in the vertical direction. Therefore, for example, compared with the case where air bags are provided on each of the upper surface 15a of the armrest portion 15 and the lower surface 16a of the cover piece 16, the number of air bags and the number of connection hoses and solenoid valves related thereto are reduced and simplified. In addition, the air bag 17 and the acupoint pressing protrusions 18 and 19 can perform high-quality treatment on the forearm A.

  (2) Since the acupoint pressing protrusions 18 and 19 are integrally formed with the cover piece 16, for example, the parts are compared with the case where the acupoint pressing protrusions 18 and 19 are attached to the cover piece 16 as separate parts. The number of points can be reduced, and a simpler configuration can be achieved.

  (3) The acupoint pressing protrusions 18 and 19 are provided independently in correspondence with Tesatori and Kakuike, which are acupoints of the user's forearm A, respectively. Thereby, Tesatori and Kyukaike can be pressed independently, and more effective treatment can be performed.

  (4) The acupoint pressing projections 18 and 19 have rectangular pressing surfaces 18a and 19a for pressing Tesatori and Kakuike, respectively, and the length in the width direction which is the longitudinal direction of the pressing surface 18a is covered. The length is approximately the same as the length of the piece 16 in the width direction, and it is formed with a sufficiently large area to press the Tesatori and the pond. Therefore, even if the forearm portion A inserted into the upper surface 15a of the armrest portion 15 is deviated from the recommended position, it is possible to stimulate Temari and the points of the curved pool. Further, it is possible to cope with a difference in the size of the user's body, that is, the size of the forearm A.

In addition, you may change embodiment of this invention as follows.
