Further, a connecting arm 14 is provided with the longitudinal direction thereof being directed in the left-right direction in a state in which the left and right rear massage parts 8, 8 are connected while traversing the rear part of the drive unit 12. The drive unit 12 swings and drives the connecting arm 14 so that the left and right ends move up and down, and gives a drive for massage operation to the left and right rear massage units 8 and 8.

Hereinafter, the configuration of each part will be described in detail.
As shown in FIG. 3, the drive unit 12 has an electric motor 17. The electric motor 17 is a dual-axis motor having a front drive shaft that protrudes forward and a rear drive shaft that protrudes rearward. The rotation drive is output to the conversion unit 32), and the rear drive shaft outputs the swing drive to the left and right rear massage units 8 and 8 (striking conversion unit 60).

  A reduction gear 18 is connected to the front drive shaft of the electric motor 17. As shown in FIGS. 6 and 7, a gear mechanism 19 such as a worm gear and a worm wheel is built in the speed reducer 18, and output rotation by the front drive shaft of the electric motor 17 is reduced by the gear mechanism 19. In addition, it is transmitted to the rotary shaft 13 in a state where the axis is orthogonal to the front drive shaft.

  When the rotating shaft 13 protrudes left and right from the speed reducer 18 of the drive unit 12, the left and right front massage parts 5 and 5 penetrate through the left and right sides, and then the left and right axial end parts are respectively casings. 3 is rotatably held by a bearing base 20 that is integrally formed or separately attached to both left and right ends of the inner wall 3. That is, both ends of the rotating shaft 13 are supported between the drive unit 12 (reduction gear 18) and the bearing base 20.

As shown in FIG.2 and FIG.3, the front massage part 5 has the roller member 23 and the massage treatment member 24, respectively. Between the left and right front massage parts 5, 5, the massage treatment members 24 are arranged so as to face each other in the left and right direction (close to each other), and the roller members 23 are arranged apart from each other in the left and right direction. ing.
That is, the massaging treatment member 24 is disposed in proximity to the left and right sides of the speed reducer 18 of the drive unit 12, and when the sole is placed on the roller member 23, It will be in the state where the massage treatment member 24 faces the inner side surface of the left-right direction among these side surfaces.

  As shown in FIG. 6, the roller member 23 is installed between the pair of flange members 25 and 26 inserted through the rotary shaft 13 and the flange members 25 and 26 so as to surround the outer periphery of the rotary shaft 13. A plurality of support shafts 27 and acupressure pieces 28 inserted into the support shafts 27 integrally or separately as skewers are provided. When the support shaft 27 and the acupressure piece 28 are separated, the acupressure piece 28 may be rotatable around the support shaft 27 or may be fixed in a non-rotating state.

The acupressure piece 28 is a disk having a diameter larger than the outer diameter of the support shaft 27, and the outer peripheral portion of the acupressure piece 28 protrudes around the support shaft 27. The outer peripheral portion of the acupressure piece 28 is rounded so as to have a semicircular cross-sectional shape.
As shown in FIGS. 2 and 4, the acupressure piece 28 includes a large disk 28 a having a large overhang around the support shaft 27 and a small disk 28 b having a small overhang around the support shaft 27. It is mixed. The ratio and the relative positional relationship in which the large disk 28a and the small disk 28b are mixed are not particularly limited. For example, the large disk 28a and the small disk 28b are alternately arranged in the circumferential direction as the roller member 23. What is necessary is just to give regularity or make it random arrangement | positioning which does not have regularity. The flange members 25 and 26 are fixed so as to rotate integrally with the rotary shaft 13 by a rotation preventing member 29, and the roller member 23 rotates integrally with the rotary shaft 13.

With such a structure, the roller member 23 is provided with a plurality of acupressure pieces 28 (a large disk 28a and a small disk 28b) on the outer peripheral surface, so that the roller member 23 is placed with the soles on the roller member 23. When 23 is rotated, the acupressure piece 28 repeats abutment and separation one after another regularly or irregularly, so that an appropriate roller massage is applied.
On the other hand, the massaging member 24 is formed in a fan shape with a plate material such as a nylon plate or a leaf spring, and can be elastically deformed in the thickness direction. As shown in FIG. 6, a swing conversion portion 32 is provided at the base of the stagnation treatment member 24, and is penetratingly held on the rotary shaft 13 via the swing conversion portion 32.

The swing conversion portion 32 has a rotating boss portion 35 fixed so as to rotate integrally with the rotating shaft 13 by an anti-rotation member 34 at an intermediate portion in the axial direction of the rotating shaft 13, and an outer peripheral portion of the rotating boss portion 35. And a restricting portion 37 that prevents the housing portion 36 from rotating together with the rotation of the rotating boss portion 35.
The housing portion 36 is formed integrally with the massaging treatment member 24 or attached as a separate body. In the present embodiment, the housing portion 36 and the massaging treatment member 24 are integrally formed with each other.

A shaft hole 38 that is not perpendicular to the end surface of the rotary boss portion 35 but is inclined at a predetermined angle is formed through the rotary boss portion 35, and the rotary shaft 13 is inserted through the shaft hole 38. Yes. Therefore, the outer peripheral surface (periphery) of the rotating boss portion 35 is a cam surface that forms an endless track while being inclined with respect to the rotating shaft 13.
A bearing 40 is fitted into the cam surface (that is, the outer peripheral surface of the rotating boss portion 35), and the housing portion 36 rotates relative to the rotating boss portion 35 via the bearing 40. A stop member 41 is attached to the rotating boss portion 35 to prevent the bearing 40 from coming off.

Between the massage treatment members 24 (oscillation conversion portions 32) provided in the left and right front massage portions 5 and 5, the rotary boss portions 35 are arranged so that the inclination directions of the shaft holes 38 are opposite to each other. It is fixed to the rotating shaft 13. For this reason, the cam surface and the bearing 40 are also in a relationship of being inclined in opposite directions between the respective rotating boss portions 35.
The restricting portion 37 includes an engaging protrusion 45 that protrudes downward from the housing portion 36 and a sliding groove 46 that faces the left and right direction so that the engaging protrusion 45 is slidable. The sliding groove 46 may be formed by a pair of front and rear ribs 47 provided so as to guide and sandwich the range in which the engagement protrusion 45 moves left and right with respect to the bottom surface in the casing 3. In addition, it is also possible to use the inside of the long hole as the sliding groove 46 by forming a long hole whose longitudinal direction is directed in the left-right direction so as to penetrate the bottom surface in the casing 3. is there.

  That is, since the engagement protrusion 45 is allowed to move only to the left and right by being obstructed by the front and rear ribs 47 (in the sliding groove 46), the stagnation treatment member 24 moves together with the rotation of the rotary shaft 13. Rotation is prevented. As a result, idling occurs between the rotating boss portion 35 that rotates integrally with the rotating shaft 13 and the housing portion 36 that is fitted to the rotating boss portion 35 via the bearing 40, and the housing portion 36 includes the rotating shaft 13. Movement that swings and rotates in the left and right direction around is transmitted. Such movement causes the stagnation treatment member 24 to swing in the left-right direction, and gives a swell massage in the left-right direction to the sole or the side of the foot next to the roller member 23.

In addition, between the left and right front massage parts 5 and 5 (between the left and right massage treatment members 24), that is, the speed reducer 18 of the drive part 12 is formed as a support part 50 for the foot. A shiatsu protrusion 51 is provided on the support portion 50.
In the present embodiment, as shown in FIG. 3, the upper cover 54 and the lower cover 55 are attached to the drive unit 12 so as to wrap the electric motor 17 through cover bodies 52 and 53. Among these, the upper cover 54 is formed with a front cover 56 protruding forward so as to cover the speed reducer 18, and an acupressure protrusion 51 is formed on the upper surface of the front cover 56.

Therefore, if the foot is placed on the support portion 50, it is possible to receive acupressure from the acupressure protrusion 51 while receiving a massage massage by the massage treatment member 24.
As shown in FIG. 3, the electric motor 17 of the drive unit 12 is provided with a tapping conversion unit 60 on the rear drive shaft, and the tapping conversion unit 60 causes the connecting arms 14 of the rear massage units 8 and 8 to swing the seesaw. Driven.

  The hit conversion unit 60 includes an eccentric rotation member 61 that is eccentrically rotated by the drive unit 12, a housing portion 62 that is formed at the left and right intermediate portion of the connection arm 14 and is slidably fitted to the periphery of the eccentric rotation member 61, The arm 14 has a restricting plate 63 made of an elastic member that prevents the left and right movements of the arm 14 but allows the left and right ends of the connecting arm 14 to move up and down and is fixed to the drive unit 12 side.

  The eccentric rotating member 61 has an eccentric shaft 65 that is eccentrically attached to the rear drive shaft of the electric motor 17 and a bearing 66 that is fitted on the eccentric shaft 65, and the eccentric shaft 65 is stretched around the eccentric shaft 65. An outer casing 67 is provided in a state of taking out. Therefore, when the rear drive shaft is rotated by driving the electric motor 17, the eccentric shaft 65 rotates eccentrically around the rear drive shaft, and at this time, the outer rod 67 causes the action of the flywheel to cause the eccentric shaft 65 to move. A rotational inertial force is applied to the rotation. Therefore, the eccentric shaft 65 can obtain a smooth eccentric rotation.

  The housing part 62 has a circular opening so that the peripheral edge of the bearing 66 in the eccentric rotating member 61 can be externally fitted, and is formed integrally with or attached to the connecting arm 14. . In this embodiment, the housing part 62 and the connection arm 14 are integrally formed with each other. The housing portion 62 is provided with a lid member 68 for preventing the subsequent removal, with the eccentric rotating member 61 (bearing 66) fitted therein.

  The restricting plate 63 is formed in a band plate shape with the longitudinal direction oriented in the left-right direction and the thickness direction directed up and down, and the long side portion on the rear edge side is aligned with the front edge portion of the connecting arm 14 Thus, the connecting arm 14 is bolted. Moreover, the long side part used as the front edge side in the control board 63 is bolt-fixed to the rear edge part with respect to the upper cover 54 which covers the electric motor 17 (refer FIG.2 and FIG.4).

The connecting arm 14 is bent so that the left and right ends protrude forward, and is formed in a U shape when seen in a plan view. A striking member 70 is provided upward at the projecting ends projecting forward at the left and right ends. The hitting member 70 has a small acupuncture protrusion protruding on the upper surface thereof.
The left and right hitting members 70 are fitted in left and right round hole portions 7 and 7 (see FIG. 1) formed on the upper surface of the casing 3 so as to freely move up and down.

From these things, when the drive part 12 is driven and the rear drive shaft of the electric motor 17 is rotated, the eccentric rotation member 61 is eccentrically rotated and the housing part 62 is also given an eccentric rotation action. As a result, the connecting arm 14 also tries to rotate eccentrically as a whole. However, the connecting arm 14 is connected to the drive unit 12 side by the restriction plate 63.
Here, the restriction plate 63 hardly deforms in the left-right direction (longitudinal direction), whereas the deformation in the up-down direction (thickness direction) occurs relatively easily. While the left and right movements are blocked, the left and right ends are allowed to move up and down.

  Thus, relative rotation due to the rotation of the bearing 66 occurs between the outer peripheral portion of the eccentric rotating member 61 and the inner peripheral portion of the housing portion 62, and as a result, the tapping members 70 provided at the left and right end portions of the connecting arm 14 are provided. It moves up and down alternately left and right. Therefore, if the soles are placed on the left and right hitting members 70, 70, massage can be performed such that the soles are hit by the hitting members 70, 70.

Next, the operation state of the foot massage device 1 according to the present invention will be described.
The user's left foot is placed on the upper surface of the casing 3 so as to cover the front massage part 5 and the rear massage part 8 located on the left side of the apparatus, and the user is covered so as to cover the right front massage part 5 and the rear massage part 8. The right foot is placed and the operation switch 10 is operated to drive the drive unit 12.

  Then, the rotating shaft 13 starts rotating, and the roller member 23 rotates integrally with the rotating shaft 13 in the left and right front massage portions 5 and 5. Since the roller member 23 is provided with a plurality of acupressure pieces 28 (a large disk 28a and a small disk 28b) on the outer peripheral surface, the acupressure pieces 28 are regularly or irregularly brought into contact with and separated from the soles one after another. Repeatedly, a comfortable roller massage is given to the sole.

Moreover, the rotational driving force from the rotating shaft 13 acts via the swing conversion part 32, and the stagnation treatment member 24 swings right and left so that the front and rear are relatively opposite. During this time, the stagnation treatment member 24 repeatedly lowers and rises slightly at the front upper end thereof, and the swaying along the longitudinal direction of the stagnation treatment member 24 is accompanied by a swell-like three-dimensional movement. It becomes.
For this reason, a comfortable massage resembling itchiness is applied to the side of the foot, which is the inner side in the left-right direction, such that it is alternately pressed back and forth by the massage treatment member 24. In addition, since the stagnation treatment member 24 can be elastically deformed in the thickness direction, it does not feel that the pressing force is too strong.

At the same time, the rotational driving force from the rotary shaft 13 acts via the tapping conversion section 60, and the connecting arm 14 moves up and down alternately at the left and right ends. As a result, the left and right tapping members 70, 70 are moved. It will vibrate up and down alternately at right and left. Therefore, a comfortable massage can be obtained in which the soles and heels are hit by these hitting members.
In addition, such a use situation is an example, and various treatments can be made by appropriately changing the treatment part placed on the left and right front massage parts 5 and 5 and the treatment part placed on the left and right rear massage parts 8 and 8. A massage will be obtained.

As is apparent from the above detailed description, the foot massage device 1 according to the present invention can perform effective massage simultaneously on a plurality of portions of the treatment section such as a foot.
In addition, since the massaging treatment member 24 is driven by the single rotating shaft 13, the arrangement space of the drive part for driving the rotating shaft 13 can also be reduced.

By the way, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
For example, as shown by a two-dot chain line in FIG. 3, the drive unit 12 outputs a swing drive to the rear massage units 8, 8 (the rear drive shaft of the electric motor 17 and the eccentric shaft 65 of the tapping conversion unit 60. It is possible to provide a one-way clutch 80 that allows transmission of rotation in only one direction.

In this way, when the drive unit 12 is driven to rotate forward, the left and right front massage units 5, 5 and the left and right rear massage units 8, 8 are operated simultaneously, and when the drive unit 12 is driven in reverse rotation, The mode can be switched so that only the left and right front massage parts 5 and 5 are operated (the left and right rear massage parts 8 and 8 are stopped).
Moreover, although the foot massage apparatus 1 which massages a user's foot was illustrated as one Embodiment of a massage apparatus, it is not limited to this embodiment. For example, it is good also as a massage apparatus which mounts a user's head in a massage apparatus and massages a neck part etc. with the front massage part 5, and massages a shoulder part and a back part with the back massage part 8.
