Description

Technical Field

[0001] The present invention relates to a massage device that imparts a vibration-based massage effect to a treatment area such as the feet. Background Technology

[0002] There has long been a commercially available massage device that uses a vibrating massage section to massage the treatment area, such as the shoulder. This massage device can be used by hand. For example, Patent Document 1 can provide an effective massage to the shoulder and the like. Specifically, Patent Document 1 discloses a small massage device comprising: a housing having a grip portion at its base end; a movable kneading body having a massage section protruding from an opening provided at the front end of the housing, and an arm integrally formed with the massage section at its base end; a fixed kneading body having a vibrating massage section protruding from an opening provided at the front end of the housing, and a vibration mechanism that causes the vibrating massage section to vibrate due to the rotational force of a drive motor; and a drive mechanism that brings the movable kneading body closer to and separates it from the fixed kneading body.

[0005] Patent document 1: Japanese Patent Application Publication No. 2010-082329. Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] So, besides handheld massage devices like those in Patent Document 1 that vibrate the massage section to massage the shoulders, there are commercially available cylindrical (roller-type) massage devices that can be placed on the floor or elsewhere to vibrate and massage the soles of the feet (https: / / www.dr-air.com / jp / ja / products / 3d-massage-roll / ). These roller-type massage devices have a built-in vibration generating mechanism.

[0008] Specifically, for example, by placing a roller-type massage device on the floor or similar surface and having a user sitting in a chair place their feet on the massage device, a vibratory massage is provided to the soles of the feet. Alternatively, by placing a roller-type massage device on the legs of a user sitting in a chair, a vibratory massage is provided to their legs.

[0009] However, the existing roller-type massage device is a device that generates vibration by rotating a weight portion (eccentric body) installed to a rotating shaft of a driving motor. Therefore, in the case of using such a roller-type massage device, for example, by placing it on a floor or the like, the entire device vibrates greatly at the time of turning on the power, and thus the vibration is transmitted to the floor or the like, and there is a risk of moving in an unexpected direction before placing the foot on the main body. That is, it is difficult to grasp the timing of turning on the power, and massage cannot be performed at a predetermined position, and thus the use of the roller-type massage device becomes difficult.

[0010] In addition, in the case of using the roller-type massage device by placing it on the legs, it is used by pushing the end portion of the device with the hand, and thus the hand is numbed or tickled due to the vibration, and a good massage effect cannot be obtained.

[0011] Therefore, the present application aims to provide a massage device in which a non-vibration portion to which vibration is not transmitted is provided in a massage device that imparts a vibration-based massage effect to a treatment portion, and thus even if it is used by placing it on a floor or the like, vibration is not transmitted to the floor or the like, and massage can be performed at a predetermined position.

[0036] Hereinafter, an embodiment of the massage device 1 to which the present application pertains will be described with reference to the drawings.

[0037] Further, the embodiment described below is one example that embodies the present application, and the present application is not limited to this specific example. Also, with regard to the drawings, in order to easily observe, a part of the constituent parts is omitted, and is depicted using an imaginary line, etc. Also, with regard to the direction, etc. of the massage device 1, for example, the left side of the paper of Figure 1 is set to "one side" of the massage device 1, and the right side of the paper is set to "the other side" of the massage device 1. Further, with regard to the direction, etc. of the massage device 1 shown in Figures 2-8 , the same is the same.

[0038] As shown in Figures 1-8 , the massage device 1 to which the present application pertains is a device that imparts a massage based on vibration to a treatment application portion such as the foot T, the leg, the waist, etc.

[0039] For example, by placing the massage device 1 of the present application on the floor F, etc. and placing the foot T on this massage device 1 by a user seated on a chair, the massage device 1 imparts a vibration massage to the sole, etc. (refer to Figure 8 ).

[0040] Also, with regard to the massage device 1 of the present application, although not shown, by placing the massage device 1 on the leg and supporting with the hand by a user seated on a chair, the massage device 1 can also impart a vibration massage to the leg. Also, by becoming a state in which the massage device 1 is sandwiched between the waist and the backrest portion by a user seated on a chair, the massage device 1 can also impart a vibration massage to the waist. ​

[0041] The massage device 1 according to the present application will be described in detail.

[0042] The massage device 1 according to the present application is characterized by having: a vibration site that imparts a vibration-based massage to the treatment site and that has a cylindrical shape; and non-vibration sites that are provided on both sides of the vibration site and that are not transmitted with vibration.

[0043] The massage device 1 according to the present application has: a vibration generation mechanism 2 that imparts a vibration-based massage to the treatment site; a base body 3 that houses the vibration generation mechanism 2; a cylindrical middle body 4 that surrounds the base body 3 in the circumferential direction and that vibrates by the vibration generation mechanism 2; a cylindrical cover body 5 that externally houses the middle body 4 and that is provided with a treatment member 6 on the surface; and a grip portion 7 that is provided to the lengthwise end portion of the cover body 5. That is, the massage device 1 according to the present application is a cylindrical vibration massage device.

[0044] Further, the massage device 1 according to the present embodiment is provided with the middle body 4. The middle body 4 is also a component that constitutes the cover body 5. That is, the cover body 5 according to the present embodiment is a member in which the cover body 5 and the middle body 4 are combined (a double-layer structure). However, for example, it can also be configured as a single-layer structure of only the cover body 5.

[0045] As shown in FIG. 1, the massage device 1 according to the present embodiment is a cylindrical vibration massage device that is provided with the vibration generation mechanism 2 that imparts a vibration-based massage to the treatment site. Figure 3 , Figure 4 As shown in FIG. 2, the vibration generation mechanism 2 has a drive motor 8 that generates a rotational driving force, a conversion component 9 that converts the rotational driving force into a vibration motion, and a vibration member 10 that is provided to the conversion component 9.

[0046] The drive motor 8 has a one-side output shaft 12a that is provided protruding from a main body portion 11 to one side, and a other-side output shaft 12b that is provided protruding from the main body portion 11 to the other side. That is, the drive motor 8 is a double-shaft (2-shaft) drive motor. The drive motor 8 according to the present embodiment outputs the rotational driving force to each of the one side and the other side via the one-side output shaft 12a and the other-side output shaft 12b.

[0047] Further, in the present embodiment, the one-side output shaft 12a side is provided as a one-side vibration generation portion 2a, and the other-side output shaft 12b side is provided as a other-side vibration generation portion 2b. The one-side vibration generation portion 2a and the other-side vibration generation portion 2b are symmetrically arranged in the lengthwise direction (in a direction along the axial direction toward the one side and the other side). That is, the one-side vibration generation portion 2a can also be said to be a member in which the other-side vibration generation portion 2b is flipped (mirror-flipped) in the lengthwise direction and arranged at a predetermined interval. In addition, the one-side vibration generation portion 2a and the other-side vibration generation portion 2b are adjacently arranged with the drive motor 8 interposed therebetween.

[0048] First, the one-side vibration generation portion 2a will be described in detail

[0049] A protruding member 13a is attached to the front end of the one-side output shaft 12a. The protruding member 13a is a member formed in a substantially cylindrical shape. Further, the protruding member 13a of the present embodiment is formed in a half-cylindrical shape.

[0050] As shown in FIG. 1, the protruding member 13a has a cylindrical portion 14a whose axis is directed to the one side, a plate member 14c provided so as to protrude from the cylindrical portion 14a, and a weight portion 14b attached to the plate member 14c. Figure 5

[0051] In the protruding member 13a, a hole portion 14d into which the one-side output shaft 12a is inserted is provided on the side opposite to the horizontal direction of the cylindrical portion 14a. The protruding member 13a is a member that eccentrically rotates (vibration is generated) based on the eccentricity of the center axis of the cylindrical portion 14a.

[0052] The cylindrical portion 14a protrudes from the wall surface on one side of the plate member 14c. The cylindrical portion 14a is disposed so that the axis L2 is directed in the same direction as the axis Ll of the one-side output shaft 12a but is not the same axis. That is, the cylindrical portion 14a is a member that eccentrically rotates based on the rotation of the one-side output shaft 12a. By the eccentric rotation of the cylindrical portion 14a with respect to the one-side output shaft 12a, the rotational motion is converted into the vibration motion by the conversion member 9a.

[0053] As for the weight portion 14b, the weight or the shape thereof or the like can be appropriately changed, and it is a member provided at a position (opposite position) opposed to the axis of the cylindrical portion 14a that eccentrically rotates and the axis of the one-side output shaft 12a. That is, the weight portion 14b is provided at a position 180° with respect to the axis of the cylindrical portion 14a.

[0054] Further, the axis of the one-side cylindrical portion 14a and the axis of the cylindrical portion (not shown) of the protruding member 13b on the other side are the same axis. That is, the one-side cylindrical portion 14a and the cylindrical portion of the protruding member 13b on the other side are not members that rotate differently from each other, such as lagging 90° rotation, rotation in the opposite direction, or the like. That is, the eccentric directions of the one-side protruding member 13a and the protruding member 13b on the other side are the same.

[0055] Further, the one-side weight portion 14b and the weight portion (not shown) of the protruding member 13b on the other side are disposed in the same direction. For example, if the one-side weight portion 14b is located on the upper side, the weight portion of the protruding member 13b on the other side is also located on the upper side.

[0056] Next, the operation of the cylindrical portion 14a and the weight portion 14b will be described.

[0057] ​The cylindrical section 14a rotates eccentrically due to the rotational driving force output from the output shaft 12a on one side. This eccentric rotation of the cylindrical section 14a transmits rotational motion to the conversion member 9a on one side. The conversion member 9a converts the rotational motion into vibrational motion. This vibrational motion, converted by the conversion member 9a, is then transmitted to the main body 11 of the drive motor 8.

[0058] However, if the counterweight 14b is not positioned on the eccentrically rotating cylindrical part 14a side, the vibration towards the main body 11 is not eliminated and is transmitted, causing the massage device 1 to vibrate significantly as a whole. If this occurs, the massage device 1 may roll in an unexpected direction.

[0059] Therefore, to prevent the aforementioned phenomenon, in this embodiment, a counterweight 14b is provided on the side of the cylindrical portion 14a. This counterweight 14b rotates around the axis of the cylindrical portion 14a by the eccentric rotation of the cylindrical portion 14a. Through the rotation of this counterweight 14b, vibrations towards the main body portion 11 are eliminated, thus suppressing the transmission of vibrations.

[0060] By incorporating the protruding member 13a of this embodiment, the conversion member 9a is converted into vibration, and the transmission of vibration from the drive motor 8 to the main body 11 is suppressed. Therefore, the grip 7a is almost not transmitted with the vibrational motion converted by the conversion member 9a and becomes a non-vibrating part. The vibrating part is limited to the cover 5 with the treatment member 6. By incorporating this configuration in the massage device 1, the user can easily hold the massage device 1 by grasping the grip 7.

[0061] A conversion member 9a is installed on one front end (cylindrical portion 14) of the protruding member 13a. In this embodiment, the conversion member 9a is a member formed in a cross shape. Specifically, the conversion member 9a is a member having four protruding pieces 15a facing mutually intersecting directions.

[0062] The space formed between each protruding piece 15a is a space for the connecting member 39 (described in detail later) that connects the base body 3a on one side and the retaining part 31 (described in detail later) to pass through. A hole 16a is provided at the midpoint of the protruding part 15a in the protruding direction.

[0063] like Figure 5 As shown in the diagram, a limiting shaft portion 21 (details to follow) is embedded in the hole portion 16a of the base body 3a. In this embodiment, two of the four protruding pieces 15a are provided with holes 16a. By embedding the limiting shaft portion 21 of the base body 3a into the hole portion 16a, the rotation of the conversion member 9a is restricted. That is, the hole portion 16a and the limiting shaft portion 21 can be described as "rotation limiting portions" that restrict the rotation of the conversion member 9a to a predetermined range.

[0064] A protruding piece 10a is provided at the front end of the protruding piece 15a. In the present embodiment, the protruding piece 10a is provided in a rectangular shape as viewed in plan. The protruding piece 10a is fitted into a rectangular fitting hole portion 25a (details will be described later) formed in the middle cylinder 4.

[0065] Further, a hole portion 17 is formed in the center of the conversion member 9a, which is the same as the hole portion 17 of the cylindrical portion 14. A bearing 18 is fitted into this hole portion 17. The conversion member 9a is rotatably mounted to the cylindrical portion 14 (the protruding member 13a) via the bearing 18.

[0066] Further, the thickness of the conversion member 9a (the depth of the hole portion 17) is substantially the same as the height of the cylindrical portion 14. Further, the height of the conversion member 9a (the distance from the front end of the protruding piece 15a to the front end of the protruding piece 15a disposed at the opposite position) is substantially the same as the inner diameter of the middle cylinder 4. In the present embodiment, the height of the conversion member 9a is about 75 mm.

[0067] The conversion member 9a is mounted to the base 3a via an elastic member 19. In detail, the elastic member 19 is a substantially cylindrical member, which is mounted so as to externally fit the limiting shaft portion 21 of the base 3a. The elastic member 19 can be formed of a flexible material (for example, a rubber bush member or the like). The elastic member 19 absorbs the rotation of the conversion member 9a, thereby suppressing the transmission of vibration to other members, and prevents damage to the massage device 1.

[0068] The conversion member 9a is rotated by being transmitted the rotational driving force from the drive motor 8 via the protruding member 13a, but is converted into vibration by being fitted into the limiting shaft portion 21 of the base 3a in the hole portion 16a, thereby limiting the rotation to a predetermined range. The protruding piece 10a provided in the conversion member 9a is fitted into the fitting hole portion 25a, and the conversion member 9a vibrates the middle cylinder 4.

[0069] As described above, the other-side vibration generating portion 2b of the present embodiment is a member which is disposed by inverting (mirror-inverting) the one-side vibration generating portion 2a. That is, since the other-side vibration generating portion 2b is substantially the same shape as the one-side vibration generating portion 2a, only the outline of the configuration will be described.

[0070] A protruding member 13b is mounted at the front end of the other-side output shaft 12b. A cylindrical portion, not shown, into which the other-side output shaft 12b is fitted, is provided protruding from the protruding member 13a. Further, with respect to the protruding member 13b, eccentric rotation can also be provided.

[0071] A conversion member 9b is attached to the front end of the protruding member 13b. The conversion member 9b of the present embodiment is a member formed in a cross shape. That is, four protruding pieces 15b are formed in the conversion member 9b so as to face in directions crossing each other.

[0072] A hole portion 16b into which a restriction shaft portion 23 (to be described later) of the base body 3b is fitted is provided at the middle of the protruding direction of the protruding piece 15b. Two hole portions 16b are provided in the conversion member 9b as well as the hole portion 16a of the conversion member 9a. By fitting the restriction shaft portion 23 of the base body 3b into the hole portion 16b, the rotation of the conversion member 9b is restricted. That is, the hole portion 16b and the restriction shaft portion 23 can be said to be a "rotation restricting portion" that restricts the rotation of the conversion member 9b to a predetermined range.

[0073] A vibration member 10b is provided at the front end of the protruding piece 15b. In the present embodiment, the vibration member 10b is provided in the same shape as the vibration member 10a. The vibration member 10b is fitted into a rectangular shaped fitting hole portion 25b formed in the middle cylinder body 4.

[0074] In addition, a hole portion (not shown) is formed in the center of the conversion member 9b and a bearing is fitted therein. The conversion member 9b is rotatably attached to the protruding member 13b via the bearing (not shown).

[0075] That is, the conversion member 9b is in the same shape as the conversion member 9a. In addition, the conversion member 9b is attached to the base body 3b via the elastic member 19. In detail, the elastic member 19 is attached in such a manner that the restriction shaft portion 23 of the base body 3b is fitted therein. The elastic member 19 absorbs the rotation of the conversion member 9b and thereby suppresses the transmission of vibration to other members, preventing damage to the massage device 1.

[0076] The conversion member 9b rotates by being transmitted the rotational driving force from the driving motor 8 via the protruding member 13b, but the rotation is restricted to a predetermined range by fitting the restriction shaft portion 23 of the base body 3b into the hole portion 16b and thereby converted into vibration. The vibration member 10b provided in the conversion member 9b is fitted into the fitting hole portion 25b, and the conversion member 9b vibrates the middle cylinder body 4.

[0077] As shown in FIG. 1, the base body 3a is attached to one side wall surface of the main body portion 11 of the driving motor 8. In detail, the base body 3a is attached to the side wall surface of the main body portion 11 via the elastic member 19. The base body 3b is attached to the other side wall surface of the main body portion 11. Figure 4

[0078] First, the base body 3a will be described in detail.

[0079] ​The base body 3a is a disc-shaped component with a predetermined thickness. The outer diameter of the base body 3a is approximately the same as the outer diameter of the main body 11 of the drive motor 8. A hole 20 is formed at the center of the base body 3a, facing the same direction as the axial direction of the disc shape. The hole 20 of the base body 3a is a through hole, through which an output shaft 12a is mounted.

[0080] A limiting shaft portion 21 is provided on the outer peripheral wall of the base body 3a. Two limiting shaft portions 21 are provided facing one side in a manner corresponding to the hole portion 16a of the conversion member 9a. That is, a pair of limiting shaft portions 21 are provided at the position facing the output shaft 12a on one side. An elastic member 19 is installed on the limiting shaft portion 21.

[0081] Furthermore, a locking piece 22 is provided on the outer peripheral wall of the base body 3a. The locking piece 22 is a plate extending to one side. The locking piece 22 is a piece whose length in the longitudinal direction is longer than the thickness of the base body 3a. That is, the locking piece 22 is provided in a state that protrudes from the base body 3a.

[0082] In this embodiment, four locking tabs 22 are provided at equal intervals on the outer peripheral wall of the base body 3a. The locking tabs 22 are components that engage with the connecting component 39 (described in detail later) by means of the space formed between the protrusions 15a of the conversion component 9a.

[0083] Since the base body 3b is a component with approximately the same shape as the base body 3a, only a general outline of its structure will be described.

[0084] A hole (not shown) is formed at the center of the base body 3b, through which the output shaft 12b on the other side passes. A limiting shaft portion 23 is provided on the outer peripheral wall of the base body 3b. Two limiting shaft portions 23 are provided at the position facing the output shaft 12b on one side, corresponding to the hole portion 16b of the conversion member 9b. An elastic member 19 is installed on the limiting shaft portion 23.

[0085] Furthermore, a locking tab 24 is provided on the outer peripheral wall of the base body 3b. The locking tab 24 is a plate extending to one side. In this embodiment, four locking tabs 24 are provided at equal intervals on the outer peripheral wall of the base body 3b. That is, the locking tab 24 engages with the connecting member 39 through the space formed between the protruding pieces 15b of the conversion member 9b.

[0086] like Figure 2 As shown, the middle cylinder 4 is a cylindrical component with an elongated length. The middle cylinder 4 has a large internal space to accommodate the vibration generating mechanism 2. Multiple insertion holes 25 are provided on the outer peripheral wall of the middle cylinder 4. Specifically, four insertion holes 25a are provided on the outer peripheral wall of one side of the middle cylinder 4.

[0087] The embedded hole portion 25a is formed in a rectangular shape as viewed from above. The vibration member 10a of the conversion member 9a is embedded in the embedded hole portion 25a. That is, the size of the embedded hole portion 25a is substantially the same as the size of the vibration member 10a.

[0088] In addition, four embedded hole portions 25b are provided in the outer peripheral wall surface of the other side of the middle cylinder body 4. The embedded hole portions 25b are formed in a rectangular shape as viewed from above. The vibration member 10b of the conversion member 9b is embedded in the embedded hole portion 25b. That is, the size of the embedded hole portion 25b is substantially the same as the size of the vibration member 10b.

[0089] The middle cylinder body 4 is coupled to the conversion member 9 via the vibration member 10 embedded in the embedded hole portion 25. If the vibration member 10 vibrates due to the conversion of the conversion member 9, the middle cylinder body 4 vibrates. In addition, in the present embodiment, the length of the middle cylinder body 4 = about 300 mm, the outer diameter = about 80 mm, and the inner diameter = about 75 mm.

[0090] As shown in FIG. 1, the cover body 5 is a cylindrical member having a length substantially the same as the length of the middle cylinder body 4. The cover body 5 has a large space inside and houses the middle cylinder body 4. A plurality of therapy application members 6 are provided in the outer peripheral wall surface of the cover body 5. Figure 1

[0091] In detail, the therapy application members 6 are provided in a manner of protruding to the radial outer side. The therapy application members 6 are provided in a plurality at a certain interval along the length direction of the cover body 5. The shape (height or width, etc.) of the therapy application members 6 can be appropriately changed according to the purpose of the therapy application.

[0092] As shown in FIG. 1, the cover body 5 is a cylindrical member having a length substantially the same as the length of the middle cylinder body 4. The cover body 5 has a large space inside and houses the middle cylinder body 4. A plurality of therapy application members 6 are provided in the outer peripheral wall surface of the cover body 5. Figure 6

[0093] The cover body 5 (the outer cylinder body 5a and the inner cylinder body 5b) is in a state of being in close contact with the middle cylinder body 4. Thus, if the middle cylinder body 4 vibrates due to the vibration of the vibration member 10, the cover body 5 vibrates therewith. As a result, the middle cylinder body 4 and the cover body 5 serve as "vibration sites".

[0094] In addition, in the present embodiment, the length of the cover body 5 = about 300 mm (substantially the same as the length of the middle cylinder body 4), the outer diameter = about 100 mm (including the height of the therapy application members 6), and the inner diameter = about 80 mm (substantially the same as the outer diameter of the middle cylinder body 4).

[0095] ​​A gripping part 7 is provided at one end of the cover 5. Specifically, a gripping part 7a is provided at one end of the cover 5. A gripping part 7b is provided at the other end of the cover 5.

[0096] The gripping parts 7a and 7b are mirror images of each other along their length and are arranged at predetermined intervals (symmetrically arranged). The gripping parts 7a and 7b are arranged adjacent to the cover body 5. The gripping part 7a will be described in detail here.

[0097] like Figure 5 As shown, the gripping part 7a is a disc-shaped component. The gripping part 7a has an outer diameter larger than that of the cover 5. An annular fitting part 26 is formed at the center of the gripping part 7a, extending through the axial direction of the disc shape. The annular fitting part 26 is fitted around the protrusion 32a that forms the retaining part 31a (details will be described later).

[0098] In this embodiment, a recess 27 is formed on the outer periphery of the grip portion 7a. The recess 27 is a member that is recessed radially inward towards the grip portion 7a. That is, the outer periphery of the grip portion 7a is a member in which the protrusion 28 and the recess 27 (peak and valley) alternately continue. When viewed from above, the grip portion 7a is a star-shaped disk member. In this embodiment, the top of the protrusion 28 is a curved but generally flat surface (not sharp).

[0099] The protrusion 28 has multiple edges. A straight edge 29 extending along the length direction (one side) of this edge becomes a mounting portion 30 capable of being placed on the floor F. Specifically, the mounting portion 30 is a combination of the edge 29a of the protrusion 28 and an edge 29b located opposite the recess 27 and the edge 29a. By bringing the straight edge 29a and the edge 29b into contact with the floor F, the mounting portion 30 becomes capable of placing the gripping part 7 on the floor F.

[0100] That is, it can be said that a mounting portion 30 is provided on the outer periphery of the grip portion 7, which can be placed on the floor F. This mounting portion 30 serves to prevent the massage device 1 from rotating when it is placed on the floor F. In other words, the mounting portion 30 can be said to be a part that has a "rotation prevention portion".

[0101] Furthermore, although the mounting portion 30 is set as the edge portion 29a, 29b of the protrusion 28 in this embodiment, a portion of the outer periphery of the grip portion 7 can also be cut off and the plane (e.g., the inclined surface of a polygon such as a pentagon) is set as the mounting portion 30 that can be placed on the floor F. The grip portion 7 is held in a movable state by the holding portion 31.

[0102] like Figures 5-7As shown in FIG. 1, the holding portion 31 has a protruding member 32 of a cylindrical shape that is fitted to the annular fitting portion 26 of the holding portion 7, a holding member 33 that holds the protruding member 32 in a loose fitting state, and a ring member 34 that is fastened to the holding member 33 to prevent the protruding member 32 from falling off.

[0103] The holding portion 31a is provided on the holding portion 7a side. In addition, the holding portion 7b is provided on the holding portion 7b side. The holding portion 31a and the holding portion 31b are members that are mirror-inverted in the length direction and arranged at a predetermined interval (symmetrically arranged). The holding portion 31a and the holding portion 31b are arranged in close proximity to the vibration generating mechanism 2. The holding portion 31a is described with attention being paid thereto. The holding portion 31a is provided on the outer side in one direction than the one-side vibration generating portion 2a.

[0104] The protruding member 32a is a cylindrical member that is fitted to the annular fitting portion 26 of the holding portion 7a. With regard to the protruding member 32a, the outer side in one direction is largely opened, and the inner side in one direction (the other direction) is provided with a bottom panel 35. That is, the protruding member 32a is a member of a bottomed cylindrical shape.

[0105] A hole portion 36 that faces in the same direction as the axial direction of the cylindrical shape is formed in the center of the bottom panel 35. This hole portion 36 is provided as a through hole that is penetrated by the holding member 33a. That is, the bottom panel 35 is provided as a ring-shaped panel member.

[0106] The hole portion 36 formed in the bottom panel 35 is a through hole having a step difference in inner diameter. The hole portion 36 is provided with a hole portion 36a, a hole portion 36b, and a hole portion 36c in this order from one side toward the other side, and each of the inner diameters is different.

[0107] First, the inner diameter φA of the hole portion 36a is slightly larger than the outer diameter φG of the annular rib member 42 that is provided to project toward the other side in the ring member 34a described later (refer to Figure 6 、 Figure 7 ).

[0108] The inner diameter φB of the hole portion 36b is slightly larger than the outer diameter φD of the cylindrical portion of the holding member 33a described later (refer to Figure 6 、 Figure 7 ).

[0109] The inner diameter φC of the hole portion 36c is slightly larger than the outer diameter φE of the rib member 37 formed in the holding member 33a described later (refer to Figure 6 、 Figure 7 ).

[0110] The holding member 33a is a member formed in a cylindrical shape. The outer diameter of the holding member 33a is smaller than the inner diameter of the convex member 32a. Specifically, the outer diameter φD of the cylindrical portion of the holding member 33a is smaller than the inner diameter of the hole portion 36b φB formed in the bottom panel 35 of the convex member 32a (refer to Figure 6 , Figure 7 ).

[0111] A rib member 37 is provided on the outer peripheral wall surface of the holding member 33a. The rib member 37 is formed in a shape protruding toward the radial outer side and curved in the circumferential direction (annular shape). That is, the rib member 37 is provided in a manner surrounding the outer periphery of the holding member 33a.

[0112] In the present embodiment, the rib member 37 is provided at four equal intervals on the outer peripheral wall surface of the holding member 33a. In addition, the rib member 37 can also be formed in an annular shape in a manner surrounding the outer periphery of the holding member 33a.

[0113] The outer diameter φE of the rib member 37 is smaller than the inner diameter φC of the hole portion 36c formed in the bottom panel 35 (convex member 32a) (refer to Figure 6 , Figure 7 ). Thus, the holding member 33a can rotatably support the convex member 32a in a loose-fitting state.

[0114] In addition, an engagement piece 38 is provided on the outer peripheral wall surface of the holding member 33a. The engagement piece 38 is provided on the other side than the rib member 37. The engagement piece 38 is provided as a plate piece extending in a manner protruding from the holding member 33a toward the other side.

[0115] In the present embodiment, the engagement piece 38 is provided at four equal intervals on the outer peripheral wall surface of the base body 3a. The engagement piece 38 is provided at a position facing the engagement piece 22 of the base body 3a. The engagement piece 38 is a member engaged by a link member 39 formed in a space between the respective protruding pieces 15a of the conversion member 9a.

[0116] The link member 39 is a member linking the holding member 33a and the base body 3a. The link member 39 is an elongated rod member formed with a long groove portion 40 in the longitudinal direction. The link member 39 is installed with the groove portion 40 covering the protruding engagement piece 22 (base body 3a) and with a fastening tool or the like. In addition, the link member 39 is installed with the groove portion 40 covering the protruding engagement piece 38 (holding member 33a) at a position facing the engagement piece 22.

[0117] That is, the link member 39 is provided in a manner standing between the holding member 33a and the base body 3a. Thus, the holding member 33a and the base body 3a are reliably fixed by the link member 39.

[0118] Further, between the holding member 33a and the base body 3a, a cross-shaped conversion member 9a is provided in a floating-like state. In addition, a protruding piece 15a of the conversion member 9a is provided protruding toward the radial outer side from the space between the adjacent link members 39. The protruding piece 15a swings in the range of the space between the adjacent link members 39.

[0119] The ring member 34a holds the protruding member 32a in a loose-fitting state by being sandwiched with the holding member 33a. The ring member 34a is interposed in the protruding member 32a and is attached to the holding member 33a by a fastening tool or the like.

[0120] The ring member 34a is a cylindrical member that is larger in one direction outer side and is provided with a bottom panel 41 in one direction inner side (the other direction). That is, the ring member 34a is a bottomed cylindrical member. A through-hole is formed in the center of the bottom panel 41.

[0121] The outer diameter of the ring member 34a is smaller than the inner diameter of the protruding member 32a (refer to Figure 6 , Figure 7 ).

[0122] A rib member 42 is provided on the bottom surface of the other side of the bottom panel 41. The rib member 42 is formed in a shape protruding toward the other side and curved in the circumferential direction (annular shape). That is, the rib member 42 is provided in a manner of surrounding in the circumferential direction.

[0123] The inner diameter φF of the rib member 42 is larger than the outer diameter φD of the cylindrical portion of the holding member 33a (refer to Figure 6 , Figure 7 ). The rib member 42 is fitted outside the holding member 33a. The ring member 34a and the holding member 33a are reliably fixed by a fastening tool or the like.

[0124] The outer diameter φG of the rib member 42 is smaller than the inner diameter φA of the hole 36a formed in the bottom panel 35 (protruding member 32a) (refer to Figure 6 , Figure 7 ).

[0125] Thus, the ring member 34a is attached to the holding member 33a in a manner of sandwiching the protruding member 32a toward the other side, and the protruding member 32a can be held in a loose-fitting state so as not to shake and to be rotatable.

[0126] A cover member 43 is attached to the opening portion of one side of the ring member 34a. The cover member 43 is a disc-shaped member. The outer diameter of the cover member 43 is substantially the same as the outer diameter of the ring member 34a. In addition, an operation switch 44 such as a power switch that drives and stops the massage device 1, a condition change button that can change the rhythm of vibration, and the like are provided in the cover member 43.

[0127] As described above, the holding portion 31b is provided on the side of the holding portion 7b. The holding portion 31b of the present embodiment is a member configured by turning over (mirror turning over) the holding portion 31a. That is, the holding portion 31b is substantially the same shape as the holding portion 31a, and thus only the outline of the configuration will be described.

[0128] The protruding member 32b is a cylindrical member fitted in the holding portion 7b. With regard to the protruding member 32b, the one direction outside is largely opened, and the one direction inside (the other direction) is provided with a bottom panel 45. That is, the protruding member 32b is a bottomed cylindrical member. The through-hole portion 46 is formed in the bottom panel 45, and is penetrated by the holding member 33b.

[0129] The through-hole portion 46 formed in the protruding member 32b is a through-hole having a step difference in inner diameter as with the through-hole portion 36 of the protruding member 32a. With regard to the inner diameter of each of the through-hole portions 46 formed in the protruding member 32b, the inner diameters of the through-hole portions 36a, 36b, 36c of the protruding member 32a are substantially the same.

[0130] The holding member 33b is a member formed in a cylindrical shape. The outer diameter of the holding member 33b is substantially the same as the outer diameter of the holding member 33a. That is, the outer diameter of the holding member 33b is smaller than the inner diameter of the through-hole portion 36b.

[0131] A rib member 47 is provided on the outer peripheral wall surface of the holding member 33b. The rib member 47 is the same shape as the rib member 37 of the holding member 33a. That is, the rib member 47 is provided so as to surround the outer periphery of the holding member 33b.

[0132] The outer diameter of the rib member 47 is smaller than the inner diameter of the through-hole portion 46 (the through-hole portion 36c) formed in the protruding member 32b. The holding member 33b can rotatably support the protruding member 32b in a loose fitting state.

[0133] In addition, an engagement piece 48 is provided on the outer peripheral wall surface of the holding member 33b. The engagement piece 48 is the same shape as the engagement piece 38 of the holding member 33a. The engagement piece 48 is provided as a plate piece extending so as to protrude from the holding member 33b to one side.

[0134] In the present embodiment, the engagement piece 48 is provided at four positions at equal intervals on the outer peripheral wall surface of the base body 3b. The engagement piece 48 is provided at a position facing the engagement piece 24 of the base body 3b. The engagement piece 48 is a member engaged by the link member 39 passing through the space formed between the respective protruding pieces 15b of the conversion member 9b.

[0135] The coupling member 39 is fitted over the groove portion 40 of the protruding engagement piece 24 (the base body 3b) and is attached by a fastening tool or the like. Also, the coupling member 39 is fitted over the groove portion 40 of the protruding engagement piece 48 (the holding member 33b) in a position facing the engagement piece 24 and is attached by a fastening tool or the like.

[0136] That is, the coupling member 39 is provided in a manner of being interposed between the holding member 33b and the base body 3b. Thus, the holding member 33a and the base body 3a are reliably fixed by the coupling member 39.

[0137] Further, between the holding member 33b and the base body 3b, the cross-shaped conversion member 9b is provided in a floating-like state. Also, the protruding piece 15b of the conversion member 9b is provided protruding toward the radially outer side and swings in a range of a space between adjacent coupling members 39.

[0138] The ring member 34b holds the protruding member 32b in a loose-fitting state by being sandwiched together with the holding member 33b. The ring member 34b is interposed in the protruding member 32b and is attached to the holding member 33b by a fastening tool or the like.

[0139] The ring member 34b is the same shape as the ring member 34a. That is, the outer diameter and the inner diameter of the ring member 34b are substantially the same as those of the ring member 34a.

[0140] A rib member is provided in the ring member 34b. The rib member is the same shape as the rib member 42 of the ring member 34a. That is, the outer diameter and the inner diameter of the rib member are substantially the same as those of the rib member 42.

[0141] Thus, the ring member 34b is attached to the holding member 33b in a manner of interposing the protruding member 32b toward the other side, and the protruding member 32b can be held in a loose-fitting state in a non-shaking and rotatable manner.

[0142] That is, the protruding member 32 is held in a loose-fitting state by the holding member 33 and the ring member 34. Also, the holding member 33 is configured to be attached to the base body 3 so as to be held in a floating state in the middle cylinder body 4 and not to transmit the vibration transmitted from the vibration generating mechanism 2 to the middle cylinder body 4. Thus, it is seen that the grip portion 7 is provided in a non-coupled state and rotatably with respect to the cover body 5 as a "non-vibration site" not to transmit the vibration from the vibration generating mechanism 2.

[0143] According to the present application, in the massage device 1 that imparts a massage effect based on vibration to the treatment application part, for example, by providing the eccentrically rotating cylindrical portion 14a to the protruding member 13a and the counterweight portion 14b disposed at a position opposite to the one side output shaft 12a and the cylindrical portion 14a, the cylindrical portion 14a is caused to transmit the rotational motion to the conversion member 9a, and the counterweight portion 14b prevents the vibration motion converted by the conversion member 9a from being transmitted to the main body portion 11 of the drive motor 8, whereby the holding portion 7 becomes a non-vibration site (vibration is not transmitted), and the vibration site is limited to the cover 5 (including the vibration generating mechanism 2 and the middle cylinder 4) provided with the treatment application member 6. In addition, the holding portion 7 becomes a member that is held in a free state with respect to the vibration site (vibration generating mechanism 2, middle cylinder 4, and cover 5).

[0144] By providing the massage device 1 with such a configuration, the user can easily hold the massage device 1 by gripping the holding portion 7. In addition, even if the holding portion 7 is placed on the floor F or the like and the massage device 1 is used, vibration is not transmitted to the floor or the like, and massage can be performed at a predetermined position.

[0145] That is, even if the power is turned on and the entire massage device 1 vibrates, vibration is not transmitted to the floor or the like, and the foot does not move in an unintended direction before being placed on the main body.

[0146] Furthermore, it should be considered that the embodiments disclosed herein are examples and are not limiting in all points.

[0147] In particular, matters not explicitly described in the embodiments disclosed herein, such as working conditions or operating conditions, dimensions, weights, and the like of the components, are not outside the range generally implemented by those skilled in the art, and matters that can be easily conceived by those skilled in the art are adopted.

[0148] For example, regarding the configuration of the non-vibration site, that is, the outer diameter and inner diameter of the protruding member 32, the holding member 33, the holding member 33, and the ring member 34 that constitute the holding portion 31, the shape or separation distance of the holding portions 7 on the left and right, the configuration of the vibration site (vibration generating mechanism 2, middle cylinder 4, and cover 5), and the like, can be appropriately changed in view of the treatment application range.

[0149] In addition, in the present embodiment, the cylindrical shape has been exemplified for the cylinder of the middle cylinder 4 or the cover 5, but it can also be a cylinder in which the radial cross section is elliptical, or a polygonal (hexagonal or the like) cylinder.
