It is a schematic sectional drawing of the heat transfer means in all the embodiment of this invention.

  First, the schematic configuration of the entire massage device according to the present invention and the schematic configuration of the treatment element portion will be described.

  FIG. 2 shows an example of the appearance of the massage device according to the present invention. A massage mechanism (not shown) that self-runs up and down is arranged in a backrest 10 that can be reclined with respect to the seat portion 1. Behind the cover 101 covering the front surface of the backrest 10 are disposed treatment elements 2 and 2 that are driven by the massage mechanism to perform a massage motion.

  As shown in FIG. 1 (a), the treatment elements 2 and 2 that are paired on the left and right are formed at the distal ends of the arms 3 and 3 that are formed of elastic bodies 20 and 20 and are driven by the massage mechanism. Each is attached. As shown in FIG. 1B, the attachment is performed by fixing the support shaft 30 to the tip of the arm 3 and disposing the treatment element 2 via the bearing 25 on the outer periphery of the support shaft 30. The child 2 is allowed to freely rotate around its axis. A disk-shaped heat transfer means 31 is provided at the axial center of the support shaft 30, and the elastic bodies 20 constituting the treatment element 2 are disposed on the left and right sides of the disk-shaped heat transfer means 31, respectively. . Here, the heat source 4 is disposed in the heat transfer means 31.

  In the massage device in which the treatment element 2 is configured as described above, when the treatment element 2 is moved and massaged on the human body while generating heat with the heat source 4, the heat of the heat source 4 is treated by the heat transfer means 31. Since it is carried to the outer peripheral part of the child 2, the outer peripheral part of the treatment element 2 which contacts a human body via the cover 101 of the backrest 10 can make a human body fully feel warmth.

  Hereinafter, characteristic portions of the present invention will be further described.

  In FIG.1 (c), the schematic perspective view of the heat-transfer means 31 in Embodiment 1 of this invention is shown. Here, the heat transfer means 31 comprised of the heat transfer means 31a and the heat transfer means 31b divided in the direction perpendicular to the support shaft 30 is used. Here, the coupling surface of each of the heat transfer means 31a and the heat transfer means 31b has a positioning structure composed of a recess 6 ′ and a protrusion 6. By fitting the recess 6 ′ and the protrusion 6, the slippage can be prevented. Position so that it does not occur. Further, the heat transfer means 31a and the heat transfer means 31b are combined with each other by a screw (not shown) or an adhesive.

  An installation hole 5 is formed at the center of the coupling surface of each of the heat transfer means 31a and the heat transfer means 31b so that the heat source 4 can be included without any gap when the coupling surfaces are coupled. . Here, a discharge port 51 through which a connection line (not shown) for supplying electric power to the heat source 4 is provided outside the heat transfer means 31 is provided so as to communicate with the installation hole 5. The heat source 4 is inserted into the installation hole 5 and is sandwiched between the heat transfer means 31a and the heat transfer means 31b. Here, the installation hole 5 of the heat source 4 is not formed on the coupling surface of both the heat transfer means 31a and the heat transfer means 31b, but only on one coupling surface, and the other coupling surface is a flat surface. The dimensional error of the installation hole 5 is halved. By doing so, the air gap formed between the heat source 4 and the heat transfer means 31 can be minimized, so that the heat conduction efficiency transmitted from the heat source 4 to the heat transfer means 31 is improved, and the human body senses heat. The time taken to do so can be shortened.

  Here, since the installation hole 5 of the heat source 4 is formed in both or one of the heat transfer means 31a and the heat transfer means 31b, the operation can be performed with the entire coupling surface exposed. Is easily secured. That is, with the configuration as described above, it is possible to provide a massage device that can efficiently transfer the heat of the heat source 4 to the human body and easily manage the dimensions of the portion where the heat source 4 is disposed.

  Subsequently, FIG. 3A shows a schematic perspective view of the heat transfer means 31 in Embodiment 2 of the present invention. In the first embodiment, the heat transfer means 31 is disc-shaped and directly provided on the support shaft 30, but in the second embodiment, the heat transfer means 31 is arranged in the vicinity of the human body. Here, in order to arrange the heat transfer means 31 in the vicinity of the human body, the support shaft 30 is provided with the disk-shaped heat transfer means holding portion 1, and the plate-shaped insertion port 8 is provided on the heat transfer means holding portion 1 near the human body. Provided. And, from the outer peripheral side of the heat transfer means holding part 1, a plate-shaped heat transfer means 31 is inserted into the insertion port 8 with the heat source 4 sandwiched between the heat transfer means 31a and the heat transfer means 31b. The heat transfer means 31 is held so as not to protrude from the outer peripheral surface of the heat transfer means holding portion 1. By doing in this way, the heat transfer means 31 can be reduced in size. Here, the heat transfer means holding part 1 and the heat transfer means 31 are provided with two positioning holes 60 each, and the holes 60 of the heat transfer means holding part 1 and the heat transfer means 31 are combined. The heat transfer means 31 is positioned and held by the heat transfer means holding portion 1 by passing through the alignment pins 61. Here, an outlet (not shown) for connecting the heat source 4 is provided on the opposite side of the heat transfer means holding portion 1 to the vicinity of the human body so as to communicate with the insertion port 8. A wire (not shown) is discharged outside through the outlet 51 of the heat transfer means 31 and the outlet (not shown).

  Here, since the heat transfer means 31 is downsized and arranged on the human body side, the capacity of the heat source 4 can be reduced and the power can be reduced. Further, by providing the heat transfer means near the human body, the time required for the human body to sense heat can be further shortened.

  Here, as a method of holding the heat transfer means 31 in the heat transfer means holding portion 1, for example, as shown in FIG. 3B, the heat transfer means 31 is provided with a taper and the heat transfer means holding portion 1 is inserted. There is a method in which a similar taper is provided at the port 8 and the heat transfer means 31 is inserted from the outer peripheral side of the heat transfer means holding portion 1 so as to be fitted to the heat transfer means holding portion 1. Here, as long as the heat transfer means 31 is securely held by the heat transfer means holding part 1, a method other than the above may be used.

  Subsequently, FIG. 4 shows the heat transfer means holding portion 1 and the heat transfer means 31 according to the third embodiment of the present invention. In the third embodiment, the heat transfer means 31 is provided with a fitting portion 11 at a portion near the human body, and the heat transfer means holding portion 1 is fitted with the fitting portion 11, whereby the heat transfer means holding portion. The heat transfer means 31 is held in 1. A predetermined gap 12 is provided so that the heat transfer means holding part 1 and the heat transfer means 31 do not come in contact with any part other than the fitting part 11. By doing in this way, the heat of the heat source 4 is concentrated and transmitted to the fitting part 11 near the human body through the heat transfer means 31, and the heat conduction efficiency to the human body can be increased. That is, the time taken for the human body to sense heat can be further shortened. Here, since the heat transfer means 31 is penetrated from the vicinity of the human body of the heat transfer means holding part 1 to the opposite side, a connection line (not shown) for supplying power to the heat source 4 as in the second embodiment. It is not necessary to provide the heat transfer means holding part 1 with a discharge port (not shown) for taking out the outside).

  Next, FIG. 5 (a) shows another shape of the heat transfer means 31 in the first embodiment of the present invention. FIG. 5B shows another shape of the heat transfer means 31 according to the third embodiment of the present invention. Here, the heat transfer means 31 is composed of a member 310 having a higher thermal conductivity on the side close to the human body than other parts. Further, the heat source 4 is disposed on the highly heat conductive member 310 side. By doing in this way, from the difference in thermal conductivity depending on the material, the heat of the heat source 4 is concentrated and transmitted to the portion with high thermal conductivity, that is, the vicinity of the human body, and the human body can be warmed quickly. . It should be noted that a metal (particularly a high thermal conductive member such as aluminum or silver) is used as the high thermal conductivity member 310 near the human body, and a resin (particularly PEEK having a high thermal resistance) is used as the low thermal conductive member 311 in other parts. It is conceivable to use PPS).

  Next, FIG. 6 shows a schematic cross-sectional view of the heat transfer means 31 in all the embodiments of the present invention. In all the embodiments of the present invention, for example, a PTC heater is used as the heat source 4. In general, the heating element of the PTC heater is generally a ceramic member. When a load such as compression or impact exceeding a certain level is applied to the ceramic member, the ceramic member easily breaks or cracks, and not only cannot produce a desired amount of heat generation, but also there is a possibility of causing problems such as ignition. In addition to the time when the heat source 4 is sandwiched so as to come into contact with the heat transfer means 31, various impacts are applied to the heat transfer means 31 by the reaction force from the human body during the massage. Therefore, it is preferable to provide the impact relaxation member 7 between the heat transfer means 31 and the heat source 4 as in the illustrated example. By doing in this way, the impact of the external force concerning the heat source 4 can be relieved, and the damage and the crack of the heat source 4 due to overload can be suppressed. Incidentally, the impact relaxation member 7 may be a suspension structure such as a leaf spring or a disc spring, or may be a material structure such as rubber or a lubricant.

  As mentioned above, although this invention was demonstrated based on embodiment shown to an accompanying drawing, this invention is not limited to said each embodiment, If it is in the range which this invention intends, an appropriate design change will be carried out. Is possible.
