Press massage is performed on the side of the.

The air bag 15 and the air pipe 16 that perform these pressure massages are attached to the frame member 8 that constitutes the skeleton of the footrest portion 3. That is, the air massage part 11 is attached to the frame member 8.
On the other hand, the foot massage part 13 provided on the lower side (foot insertion part 18) of the insertion recess 9 performs vibration massage on the back side (foot sole) of the foot part.

  As shown in FIGS. 3 and 4, the foot massage part 13 is for vibrating and massaging the sole of the foot part of the user U inserted into the insertion recess 9 from below. Specifically, the foot massage unit 13 includes a vibration motor 19 that generates vibration housed in the foot insertion unit 18, a treatment element 12 that vibrates and massages the sole of the user U, and a treatment element 12. And a diaphragm 20 that transmits vibration generated by the vibration motor 19 to the treatment element 12.

  The vibration motor 19 is disposed such that the rotation shaft faces downward, and is provided at the center in the left-right direction. Since a vibration generating unit 21 described later is provided at the tip of the rotating shaft of the vibration motor 19, vibration is generated with the rotation of the rotating shaft. The vibration motor 19 is disposed inside a side wall portion located between a pair of left and right foot insertion portions 18 provided.

  Inside the side wall portion, the vibration motor 19 is fixed to the upper surface of a rectangular support plate 22 using four screws 23 as viewed from above. Further, the support plate 22 has a width in the left-right direction substantially equal to that of the vibration motor 19 and a length in the front-rear direction that is longer than that of the vibration motor 19, and four vibration motor columns 24 arranged at four corners. It is supported from below using the (second vibration isolation member 14).

  The upper ends of the four vibration motor columns 24 are connected to the lower surface of the support plate 22, and the lower ends are fixed to the frame member 8 using the mounting base 30. The vibration motor column 24 is a frame member of the footrest 3. 8 and the vibration motor 19 are connected. The frame member 8 to which the vibration motor 19 is connected is a support member that constitutes the lower side of the insertion recess 9 (foot insertion portion 18).

Each vibration motor support 24 is formed in a cylindrical shape by an elastic material (anti-vibration rubber) combining natural rubber, styrene butadiene rubber, chloroprene rubber, nitrile rubber, etc., and is generated by the vibration motor 19. It is possible to suppress the transmitted vibration from propagating to the frame member 8.
The frame member 8 to which the vibration motor support 24 is fixed is formed to have a rectangular frame shape when viewed from above. The four struts that support the vibration motor 19 are fixed to the center of the frame member 8 in the left-right direction.

If the vibration motor 19 located in the center in the left-right direction is used to vibrate the two treatment elements 12 located on the left and right sides, it is not necessary to provide a vibration motor for each treatment element and drive it. It is possible to simplify the configuration of the machine.
On the other hand, the treatment element 12 disposed at a position corresponding to the back side of the foot of the user U is a member having a substantially hemispherical appearance that bulges upward. A crucible pushing protrusion 25 is formed on the upper side of the treatment element 12 so as to protrude further upward. When the treatment element 12 is vibrated, the crucible pushing protrusion 25 forms a treatment part (cage) on the sole of the user U. It can be stimulated. The left and right treatment elements 12 are both fixed at the lower end to the diaphragm 20, and the treatment element 12 can be vibrated in the same direction as the diaphragm 20 by vibrating the diaphragm 20.

  The diaphragm 20 (the portion shown in gray in FIGS. 4 and 5) in which the treatment element 12 is integrally formed is a plate shape formed in a rectangular shape that is long in the left-right direction when viewed from above. It is a member. The diaphragm 20 is folded back up and down a plurality of times in the left-right direction, and the left end side, the center side, and the right end side in the left-right direction protrude upwardly as seen from the front. It has a shape like this. The treatment element 12 described above is integrally formed between the protruding portions, in other words, the recessed portion when viewed from the front.

The treatment element 12 described above may be formed integrally with the diaphragm 20 by injection molding or the like. Alternatively, the treatment element 12 may be formed as a separate member from the diaphragm 20 and fitted or screwed. Alternatively, the treatment element 12 may be fixed to the diaphragm 20 using screws or the like.
Further, on the left end side and the right end side of the convexly protruding diaphragm 20, diaphragm struts 26 (first vibration isolation members 14) that fix the diaphragm 20 to the frame member 8 are provided. A total of four diaphragm struts 26 are provided for each of the left end side and the right end side of the diaphragm 20 in a line in the front-rear direction. The diaphragm support 26 is also formed in a cylindrical shape with the same elastic material as that of the vibration motor support 24 described above, and vibration generated between the frame member 8 of the footrest portion 3 and the diaphragm 20 can be suppressed. It is like that.

  Moreover, the center side of the convexly oscillating diaphragm 20 is formed in a quadrangular shape when viewed from above, and the diaphragm 20 is vertically arranged at the four corners on the central side of the rectangular diaphragm 20. A penetrating through hole 27 is formed. A vibration motor support 24 formed in a cylindrical shape is inserted into the through hole 27. Specifically, the through-hole 27 is formed in a circular shape having a diameter larger than the outer diameter of the vibration motor support 24, and is spaced apart from the diaphragm 20 even when the vibration motor support 24 vibrates. Is formed.

Further, a vibration generating unit 21 that converts the rotational driving force generated by the above-described vibration motor 19 into vibration is provided on the center side of the convexly protruding diaphragm 20.
That is, the vibration generating unit 21 is a disk-shaped member attached to the lower end of the rotating shaft that extends downward from the vibration motor 19. The disk-shaped vibration generating unit 21 has a rotationally symmetric structure in which the rotation shaft of the vibration motor 19 is attached to the center of the disk, but the center of gravity is a weight that is eccentric from the center of the disk. (Eccentric load disk). Therefore, if the rotation shaft of the vibration motor 19 is rotated, vibration is generated in the vibration generating unit 21 due to eccentric rotation, and the vibration generated in the vibration generating unit 21 is transmitted to the vibration plate 20, so that the vibration plate 20 is vibrated. It becomes possible.

As described above, the vibration is attenuated by the first vibration isolation member 14 (vibration plate support 26) and the second vibration isolation member 14 (vibration motor support 24) connecting the vibration plate 20 and the frame member 8. If such a structure is adopted, the generated vibration is suppressed from propagating from the diaphragm 20 to the frame member 8.
Incidentally, as shown in FIG. 5, in the lower limb massage machine 1 of the present embodiment, in order to ensure the connection of the diaphragm 20 to the frame member 8, the back surface of the treatment element 12 and the frame member 8 are treated. It is connected with the child support portion 28 (third vibration isolation member 14). The treatment element support portion 28 (third vibration isolation member 14) is also formed of the same elastic body as the diaphragm support 26 and the vibration motor support 24.

  By the way, as shown in FIG. 5, the air pipe 16 that sends air to the air massage part 11 circulates inside the footrest part 3 and connects the pump and the air bag 15 (air bag). The air pipe 16 is laid on the frame member 8, and is disposed at a position away from the above-described diaphragm 20 and vibration motor 19, and vibration is generated at the connection portion of the air pipe 16 and the air pipe 16. The influence is taken so that air does not leak from the air pipe 16. For example, taking the periphery of the diaphragm 20 as an example, the air pipe 16 is laid with a distance further forward from the front end of the diaphragm 20 and further provided with a distance rearward from the rear end. The vibration of the diaphragm 20 is not transmitted to the pipe 16.

Next, a method of massaging the lower limbs using the above-described foot massage part 13, in other words, an operation mode of the lower limb massage machine 1 provided in the chair type massage machine 2 of the present invention will be described.
First, about the air massage part 11, a pump etc. are started, air is sent to the air massage part 11, and the air bag 15 of the air massage part 11 is expanded. Then, the air bladder 15 is inflated, and is pushed by the inflated air bladder 15 so that a massage plate or the like presses the treatment portion, and massage is performed.

  At this time, the vibration motor 19 is generated by the foot massage unit 13. Then, the rotation generated by the vibration motor 19 is transmitted to the vibration generation unit 21 via the rotation shaft, and the vibration generation unit 21 rotates. Since the vibration generating unit 21 has a structure having a weight at an eccentric position as described above, the vibration generating unit 21 generates vibration when the vibration generating unit 21 is rotated around the rotation axis. The vibration generated by the vibration generating unit 21 is transmitted to the diaphragm 20, and the diaphragm 20 vibrates.

When the vibration plate 20 vibrates, the treatment element 12 fixed to the vibration plate 20 also vibrates, and the urn push projection 25 attached to the upper end of the treatment element 12 stimulates the acupuncture points on the sole, so On the other hand, it becomes possible to perform foot massage.
In addition, the vibration massage in the above-mentioned foot massage part 13 and the air massage in the air massage part 11 may operate in conjunction with each other, or may operate independently.

  For example, as a usage mode in which the massage parts 11 and 13 are interlocked, the air bag 15 of the air massage part 11 is first inflated to fix the user's lower limb (calf), and the calf is fixed. The thing which performs a vibration massage using the treatment element 12 to a user's leg (foot sole) can be mentioned. By doing in this way, it becomes possible to carry out vibration massage of a user's sole effectively. In addition, it is possible to change the sensation given to the user who receives the massage, and it is possible to perform a massage with more variations.

  The above-described diaphragm 20 is attached to the frame member 8 via a diaphragm support 26 that is the first vibration isolation member 14, and the vibration motor 19 described above is a vibration motor that is the second vibration isolation member 14. It is attached to the frame member 8 via a support post 24. In addition, the vibration motor support 24 is inserted into the through hole 27 of the vibration plate 20 at a distance that does not contact the vibration plate 20 during vibration. That is, vibration generated by the vibration motor 19 may be transmitted to the diaphragm 20, but not transmitted from the vibration motor 19 to the frame member 8, or transmitted from the diaphragm 20 to the frame member 8. . Therefore, the vibration is not transmitted to the air pipe 16 disposed on the frame member 8 or the connection part of the air pipe 16, and the vibration loosens the connection part of the air pipe 16 and causes air leakage from the air pipe 16. Is suppressed, and the air massage mechanism and the vibration massage mechanism can be combined and used without any trouble.

  The present invention is not limited to the above-described embodiments, and the shape, structure, material, combination, and the like of each member can be appropriately changed without changing the essence of the invention. In particular, in the embodiment disclosed this time, matters that are not explicitly disclosed, for example, operating conditions and operating conditions, various parameters, dimensions, weights, volumes, and the like of a component deviate from a range that a person skilled in the art normally performs. Instead, values that can be easily assumed by those skilled in the art are employed.

For example, in the present embodiment, the lower limb massage machine 1 has been described as being attached to a chair type massage machine 2 as shown in FIG. 1 (footrest portion 3), but is not limited to this embodiment. The present invention can be realized even with a single leg massage machine 1.
Also, the upper side of the insertion recess 9 (leg insertion part 17) and the lower side of the insertion recess 9 (foot insertion part 18) of the lower limb massage machine 1 are the foot insertion part 18 relative to the leg insertion part 17. It is also possible to adopt a configuration in which they are moved closer to and away from each other by moving means for moving them closer to and away from each other. The moving means is composed of an arm member that connects the leg insertion portion 17 and the foot insertion portion 18 and operates to move the foot insertion portion 18 close to and away from the leg insertion portion 17. Good.

  Moreover, as shown in FIGS. 2-4, it is good for the front-and-back part of the treatment element 12 to be provided with the thermal means 29 for heating the user's U sole. The heating means 29 may be composed of a surface heater such as a PTC heater, for example, and may be fixed to the frame member 8. Thus, if the heating means 29 is fixed to the frame member 8 to which vibration does not propagate, vibration will not be transmitted to the heating means 29 itself. However, it is also possible to fix the heating means 29 to the diaphragm 20 or the like and vibrate the heating means 29 together with the diaphragm 20.
