Description

Massage device

Technical Field

The present invention relates to a massage device for massaging a treatment site of a user from the back to the legs by pressing the treatment site.

Background

In recent years, users are proposing various expectations regarding massage. In order to cope with such a desire, development of massage apparatuses is underway. For example, there is a massage apparatus capable of massaging the lower limbs (particularly, the region from the back of the legs to the buttocks) of a user (for example, see patent document 1).

Patent document 1: japanese patent publication No. JP 2013-248144 (Kokai).

However, the massage mechanism mounted on the massage device disclosed in patent document 1 can massage the treatment site from the back of the leg (thigh) to the hip, but is mounted on a large-sized chair-type massage machine. Therefore, the main body (unit) of the massage mechanism is a thick and large unit.

The massage mechanism has a large and complicated structure among various mechanisms, and is large in size even when mounted on a large chair-type massage machine. Further, as the cell becomes thicker, the operation of the cell also increases.

However, in recent years, a demand or desire for a massage apparatus which is compact and small has also been developed. In other words, a model that can be placed on a seat portion of a general-type chair such as an office chair and can massage a treatment portion from the back of a leg to the hip of a seated user is also expected.

In this regard, the massage mechanism of patent document 1 cannot cope with the demand for a small-sized massage device. Such a large massage mechanism is known, for example, by referring to fig. 11 of the document, and has a complicated structure, and it is difficult to easily miniaturize the massage mechanism. Further, it is considered that the massage mechanism alone cannot be used as a massage device in a seat portion of a general chair.

Detailed Description

Hereinafter, an embodiment of the massage apparatus 1 according to the present invention will be described with reference to the drawings.

The embodiments described below are merely examples embodying the present invention, and the configuration of the present invention is not limited to the specific examples. In the drawings, a part of the structural components is omitted or drawn with a phantom line or the like for easy viewing.

The massage device 1 is shown in the drawings in the front-back direction, the left-right direction, and the like. The massage device 1 shown in fig. 8 is placed on a chair C (e.g., an office chair) or the like, and is aligned with the direction viewed from the user seated on the massage device 1. In the following description, the direction shown in fig. 1-8, etc. is used as the direction for explaining the massage device 1 of the present invention.

Fig. 1-fig. 8 shows a massage device 1 according to an embodiment of the present invention.

As shown in fig. 1, 8, and the like, the massage device 1 of the present embodiment is used by being placed on a seat surface of a chair C, a sofa, or the like. That is, the user U sits on the massage device 1 placed on the seat surface of the chair C. The user U drives the massage mechanism 2 incorporated in the massage device 1 to press and massage the treatment site including at least the hip T.

The massage device 1 includes a massage mechanism 2 for massaging a treatment portion such as a hip T of a user U, and a seat portion having a width allowing the user U to sit thereon and including a frame-shaped support frame 3 for housing the massage mechanism 2.

The treatment portion preferably has a wide region from the leg back portion B (thigh portion) to the hip T. The entire body in which the outer side of the support frame 3 (housing) accommodating the massage mechanism 2 is covered with a cover, a cushion member, or the like (not shown) is a seat portion of the massage device 1.

The support frames 3 are provided on both left and right sides of the massage mechanism 2, and each are a flat rectangular frame body having a 1 st frame member 3a and a 2 nd frame member 3b, the 1 st frame member 3a movably supporting the massage mechanism 2 in the front-rear direction, and the 2 nd frame member 3b being provided so as to be bridged between the front and rear portions of the 1 st frame member 3a as a pair of left and right.

Specifically, the support frame 3 is formed in a thin shape like a seat cushion so that the user U can easily sit on. That is, the support frame 3 is a frame body having a wide seat surface and a small thickness. The "thin" includes not a thin object such as a plate material but an object having a constant thickness such as a seat cushion or a cushion.

The support frame 3 has a width sufficient for the user U to sit down. The support frame 3 of the present embodiment has a dimension (length) in the front-rear direction of about 400mm, a dimension (width) in the left-right direction of about 400mm, and a dimension (thickness) in the up-down direction of about 100mm.

As shown in fig. 1-3, the support frame 3 is provided on the front, rear, left, and right sides of the massage mechanism 2 so as to surround the outer side of the massage mechanism 2. That is, the support frame 3 is a rectangular frame body formed by combining 4 rod- like frame members 3a and 3b in a matrix (square shape) in plan view.

Specifically, the support frame 3 is a rectangular frame body including a 1 st frame member 3a (main frame) and a pair of front and rear 2 nd frame members 3b (sub-frames), the 1 st frame member 3a (main frame) is provided on both left and right sides of the massage mechanism 2 to support the massage mechanism 2 movably in the front-rear direction, and the pair of front and rear 2 nd frame members 3b (sub-frames) is provided in front and rear portions of the pair of left and right 1 st frame members 3a so as to be laid over each other.

The 1 st frame member 3a (main frame) is a long rod-like member and is disposed in the front-rear direction. The 1 st frame member 3a is provided in a pair on the left and right across the massage mechanism 2.

That is, the 1 st frame member 3a is composed of a left 1 st frame member 3a disposed on the left side of the massage mechanism 2 and a right 1 st frame member 3a disposed on the right side of the massage mechanism 2. The 1 st frame member 3a is provided with a rail portion 5 (details will be described later) for guiding the massage mechanism 2 in the front-rear direction, and the like.

The 1 st frame member 3a has a cross-sectional shape longer in the vertical direction than in the horizontal direction. The 1 st frame member 3a is formed to have a constant width (thickness) with respect to its width (dimension in the left-right direction). This enables the massage mechanism 2 to be stably supported.

In the present embodiment, the 1 st frame member 3a has a length (dimension in the front-rear direction) of about 400mm, a height (dimension in the vertical direction) of about 100mm, and a width of about 40mm.

Further, a guide groove portion 4 that is long in the front-rear direction is formed on one side surface of the 1 st frame member 3a (main frame). The guide groove portion 4 is formed so as to open on a side surface facing the massage mechanism 2.

For example, in the case of the 1 st frame member 3a on the left, the guide groove portion 4 is formed on the right lateral face. Further, in the case of the 1 st frame member 3a on the right side, the guide groove portion 4 is formed on the left side surface. The guide groove portions 4 open toward each other toward the massage mechanism 2 located inside the support frame 3.

Each guide groove portion 4 is recessed in a groove shape (stepped groove) in a deeper step in the left-right (width) direction of the 1 st frame member 3a. The guide groove portion 4 is provided with a guide rail portion 5 described later. Further, a 1 st guide groove 6 and a 2 nd guide groove 7 (both described in detail later) are provided on the bottom surface (the surface of a portion recessed in a stepped shape) of the guide groove portion 4.

The openings of the 1 st guide groove 6 and the 2 nd guide groove 7 are provided toward the massage mechanism 2 side. A 2 nd guide groove 7 is provided above the 1 st guide groove 6. That is, the 1 st guide groove 6 and the 2 nd guide groove 7 are arranged in the vertical direction.

Wherein the guide rail part 5 is installed at the opening edge of the 1 st guide groove 6 in an adjacent manner. These 1 st guide groove 6 and 2 nd guide groove 7 are members constituting a moving mechanism 15 (details will be described later), and the moving mechanism 15 guides the massage mechanism 2 in the front-rear direction.

On the other hand, the 2 nd frame member 3b (sub-frame) is a long rod-like member and is disposed in the left-right direction. The 2 nd frame member 3b is provided in a pair in the front and rear direction with the massage mechanism 2 interposed therebetween.

The 2 nd frame member 3b is attached in a direction (orthogonal direction) intersecting with respect to the 1 st frame member 3a (main frame). That is, the 2 nd frame member 3b is composed of a front 2 nd frame member 3b and a rear 2 nd frame member 3b, the front 2 nd frame member 3b connects and fixes the front ends of the left and right 1 st frame members 3a to each other, and the rear 2 nd frame member 3b connects and fixes the rear ends of the left and right 1 st frame members 3a to each other. The support frame 3 is provided as a strong frame body by the 2 nd frame member 3b and the 1 st frame member 3a.

In the present embodiment, the length (in the left-right direction as the support frame 3) of the 2 nd frame member 3b is about 400mm. However, the width and height of the 2 nd frame member 3b can be changed as appropriate.

The front 2 nd frame member 3b is preferably thinner (thinner) than the 1 st frame member 3a because it hits against the lower limbs (legs, knees, etc.) of the user U seated on the massage device 1. The 2 nd frame member 3b may be attached to the lower side of the treatment member of the massage mechanism 2 in both front and rear directions.

In this way, the support frame 3 is a frame body formed in a quadrangular shape (substantially square shape) in plan view by the 1 st frame member 3a and the 2 nd frame member 3 b. A massage mechanism 2 capable of pressing and massaging a portion (treatment portion) from the leg back B to the hip T of the user U is provided at the center side of the support frame 3.

The massage mechanism 2 performs a pressing massage by protruding and retracting from the lower side to the upper side with respect to the treatment portion (the leg back portion B, the hip portion T, and the like) of the seated user U while moving in the front-rear direction. The massage mechanism 2 of the present embodiment may be referred to as a hip massage mechanism.

The massage mechanism 2 is provided on the base 8. The base 8 is a member elongated in the left-right direction. The base 8 is provided so as to span between the pair of right and left 1 st frame members 3a. The base 8 can move in the front-rear direction. That is, the left and right ends of the massage mechanism 2 are coupled to the support frame 3 (the 1 st frame member 3 a) via a later-described moving mechanism 15 so as to be movable in the front-rear direction.

The massage mechanism 2 includes a treatment tool 9, a massage body 10, and a driving unit 11, the treatment tool 9 massages a treatment region, the treatment tool 9 is provided at a distal end of the massage body 10, and the driving unit 11 performs a protrusion/retraction motion for protruding and retracting the treatment tool 9 (the massage body 10) in the vertical direction, and moves the massage mechanism 2 in the support frame 3 (the frame body) in the vertical direction.

The drive unit 11 is provided on the base 8. The driving unit 11 includes a driving motor 12, a rotating shaft 13, a protrusion/retraction converting unit 14 (eccentric converting unit), and a moving mechanism 15, the driving motor 12 outputs a rotational driving force, the rotating shaft 13 has an axis extending in the left-right direction and is rotated by the rotational driving force output from the driving motor 12, the protrusion/retraction converting unit 14 (eccentric converting unit) converts the rotational driving force from the rotating shaft 13 into an eccentric motion for the protrusion/retraction motion, and the moving mechanism 15 moves the massage mechanism 2 in the front-rear direction.

As shown in fig. 1-5, the drive motor 12 is provided in the center of the base 8 in the left-right direction and on the front side. The output shaft 12a of the drive motor 12 is disposed in the left-right direction (in the present embodiment, the right direction). A 1 st worm 18 of the reduction mechanism 16 is mounted at the output shaft 12a, and these members rotate together.

The reduction mechanism 16 is housed in a gear case 17 provided in the base 8. The speed reduction mechanism 16 includes a 1 st worm 18, a 1 st worm wheel 19, a power transmission shaft 20, a 2 nd worm 21, a 2 nd worm wheel 22, and the like.

The 1 st worm 18 is engaged with the 1 st worm wheel 19 provided on the lower side. The 1 st worm wheel 19 is installed on the front side of the power transmission shaft 20.

The power transmission shaft 20 is disposed in a direction (front-rear direction) orthogonal to the output shaft 12a disposed on the upper side.

The power transmission shaft 20 is rotatably supported by the base 8 via a bearing 23. A 2 nd worm 21 is mounted on the rear side of the power transmission shaft 20. The 2 nd worm 21 and the 1 st worm wheel 19 rotate together with the power transmission shaft 20.

The 2 nd worm 21 is engaged with the 2 nd worm wheel 22 provided on the upper side. The 2 nd worm wheel 22 is attached to a middle portion in the longitudinal direction of the rotary shaft 13 and rotates together with the rotary shaft 13.

The axis of the rotating shaft 13 is oriented in the left-right direction and is disposed at the center of the base 8. The rotary shaft 13 is provided in a direction (right-left direction) perpendicular to the power transmission shaft 20 provided on the lower side.

The rotary shaft 13 is rotatably supported by the base 8 via a bearing 23. The rotary shaft 13 is provided in a direction (right-left direction) perpendicular to the power transmission shaft 20.

The rotational driving force output from the output shaft 12a of the drive motor 12 is transmitted to the rotary shaft 13 via the speed reduction mechanism 16 in the gear box 17. Thus, the rotary shaft 13 is rotationally driven around the shaft in the left-right direction by the rotational driving force generated by the driving motor 12.

In the present embodiment, 1 drive motor 12 and 1 rotation shaft 13 are provided. That is, in the massage apparatus 1 of the present embodiment, the massage mechanism 2 is moved in the front-rear direction by the movement mechanism 15 described later by the rotational drive of the one drive motor 12 and the rotating shaft 13, and the treatment implement 9 provided at the distal end is moved in the upward-downward projecting and retracting direction by eccentrically rotating the massage body 10 in the upward-downward direction by the projecting and retracting conversion unit 14 described later. That is, the treatment tools 9 move in the front-rear direction and the up-down direction, and thus trace of the waveform is drawn.

Next, the rotary shaft 13 includes a protrusion/retraction converting portion 14 for converting the rotational driving force of the rotary shaft 13 into the vertical protrusion/retraction movement of the massage body 10 on the left and right sides of the 2 nd worm wheel 22. The protrusion/retraction switching section 14 is provided at the proximal end portion of the massage body 10.

The massage body 10 is provided on the base 8. The massage bodies 10 are provided in a pair of left and right sides at a predetermined interval. The massage body 10 is converted into an eccentric motion by a rotational driving force of the rotating shaft 13, and is protruded and retreated from the lower side to the upper side.

The massage body 10 has a front arm member 24 and a rear arm member 25, the front arm member 24 extends forward, and the rear arm member 25 extends rearward. The base end of the front arm member 24 is connected to the base end of the rear arm member 25, and the base end thereof is provided with the protrusion/retraction converter 14. The massage body 10 is a substantially T-shaped member when viewed from the side.

The massaging member 10 is not restricted (freely) in rotation about the axis of the rotation shaft 13. That is, in the present embodiment, the massage body 10 is not provided with a biasing mechanism (restricting mechanism) such as a spring that performs a return operation by a reaction force.

Thereby, the massage body 10 can smoothly move in the front-rear direction along the shape from the back B to the hip T of the user U. Therefore, when the treatment members 9 are moved forward and backward, excellent pressing massage can be performed on the parts from the leg backs B to the buttocks T of the user U.

On the other hand, treatment tools 9 for massaging (treating) the treatment portion of the user U are provided at the tip (front end) of the front arm members 24 and the tip (rear end) of the rear arm members 25. The treatment members 9 are used for pressing and massaging the portion (treatment portion) from the back B to the buttocks T of the user U from the lower side to the upper side. That is, the treatment members 9 perform the protrusion and retraction movement in the vertical direction by the vertical eccentric movement of the massage bodies 10 by the protrusion and retraction switching portion 14.

In the present embodiment, a shaft portion 26 having an axial center in the left-right direction (the same direction as the rotation shaft 13) is attached to the tip end of each arm member. The treatment tool 9 is a rotatable roller and is mounted to rotate around the axis of the shaft 26. That is, the treatment tool 9 of the present embodiment smoothly rotates along the treatment portion from the leg back portion B to the hip portion T of the user U when the massage mechanism 2 moves in the front-rear direction.

That is, the massage mechanism 2 of the present embodiment can perform a pressing massage (push massage) by repeatedly pressing the treatment instrument 9 from below to above against the treatment site of the seated user U by vertically projecting and retracting the massage body 10.

The massage mechanism 2 according to the present embodiment is configured to repeatedly press and massage the treatment site, but may be configured to perform a massage by stretching the muscles of the leg and back B, or may be configured to combine various massage operations.

As shown in fig. 6, the protrusion/retraction converting section 14 converts the rotational driving force of the rotating shaft 13 into eccentric rotation, and performs protrusion/retraction movement for protruding and retracting the treatment applying members 9 of the massage bodies 10 in the vertical direction. The protrusion/retraction switching section 14 (eccentric switching section) includes a hub member 27 attached to the rotary shaft 13 and eccentrically rotating with respect to the axis of the rotary shaft 13, and an annular fitting section 28 provided at the proximal end of the massage body 10 and externally fitted to the hub member 27.

That is, the protrusion/retraction switching portion 14 eccentrically rotates about the axis of the rotation shaft 13 via the hub member 27 (eccentric hub member), and the annular fitting portion 28 moves in the vertical direction, thereby causing the massage member 10 to perform a protrusion/retraction operation in the vertical direction, and causing the treatment member 9 to perform a protrusion/retraction movement in the vertical direction.

The eccentric hub member 27 is mounted to rotate integrally with the rotary shaft 13. The eccentric hub member 27 includes a cam surface 27a on the outer peripheral surface, which rotates around the axis of the rotary shaft 13 eccentrically with respect to the axis. The annular fitting portion 28 is slidably fitted to the cam surface 27a of the eccentric hub member 27.

The axial center of the eccentric hub member 27 is not the same, but is oriented in the same direction (left-right direction) as the axial center of the rotating shaft 13. That is, the axis of the eccentric hub member 27 is parallel to the axis of the rotary shaft 13. The eccentric hub member 27 of the present embodiment is a two-piece member, and is configured to sandwich the annular fitting portion 28 from the left and right.

The annular fitting portion 28 is formed in an annular shape in a side view and is formed on the proximal end side (lower end side) of the massage body 10 (arm member). The annular fitting portion 28 is fitted to the cam surface 27a of the eccentric hub member 27.

The annular fitting portion 28 is rotatable relative to the eccentric hub member 27, and converts the rotational movement of the rotating shaft 13 into eccentric rotation, and converts the eccentric rotation into a projecting and retracting movement in the vertical direction of the massage body 10. That is, the eccentric hub member 27 eccentrically rotates while sliding in the annular fitting portion 28, so that the annular fitting portion 28 moves in the vertical direction, the massage body 10 protrudes and retreats in the vertical direction, and the treatment applying member 9 protrudes and retreats in the vertical direction.

The eccentric hub member 27 and the annular fitting portion 28 may be formed of a material having low abrasion resistance (e.g., fluororesin (PTFE)).

The massage body 10 is a member having a rod-shaped front arm member 24 and a rod-shaped rear arm member 25, the rod-shaped front arm member 24 is provided with an annular fitting portion 28 at a base end thereof and extends obliquely forward and upward from the base end, and the rod-shaped rear arm member 25 extends obliquely rearward and upward. That is, the protrusion/retraction switching portion 14 is provided at the base end of the massage body 10.

Further, treatment members 9 for massaging the treatment portion are provided at the front ends of the front arm members 24. Similarly, treatment members 9 for massaging the treatment portion are provided at the rear ends of the rear arm members 25. The treatment tool 9 is formed in a roller shape that rotates around the axis of the shaft 26.

That is, in the present embodiment, the treatment members 9 of 4 roller shapes are provided at the ends of the arm members 24 and 25, and can smoothly rotate along the treatment portions from the leg back portions B to the hip T of the user U when moving in the front-rear direction.

By the switching operation of the protrusion/retraction switching unit 14 (switching the rotational motion of the rotating shaft 13 to the protrusion/retraction motion in the vertical direction), the massage body 10 can repeatedly perform the protrusion/retraction motion in the vertical direction, and the treatment implement 9 moves vertically while moving back and forth, thereby repeating the wave-like motion (trace of the drawn waveform). That is, the protrusion/retraction switching unit 14 and the massage body 10 repeat the operation of pressing and pulling the treatment tool 9 moving forward and backward upward at a constant interval.

However, the massage device 1 of the present invention includes a moving mechanism 15 capable of moving the massage mechanism 2 in the front-rear direction with respect to the support frame 3. The moving mechanism 15 includes a guide rail portion 5 and a traveling body 29, the guide rail portion 5 is provided on the 1 st frame member 3a (main frame), and the traveling body 29 is provided so as to be capable of traveling on the guide rail portion 5.

As shown in fig. 4, 5, and the like, the rail portion 5 is provided in the front-rear direction on the 1 st frame member 3a. The guide rail portion 5 is a rail member for guiding the massage mechanism 2 in the front-rear direction, and is attached along the opening edge on the lower side of the guide groove portion 4 of the 1 st frame member 3a. The rail portion 5 is provided adjacent to the 1 st guide groove 6. That is, the guide rail portion 5 and the 1 st guide groove 6 are in a communicating state.

Further, a rack 30 having teeth facing in the front-rear direction is formed on the upper surface of the rail portion 5. Therefore, the traveling body 29 of the present embodiment is a pinion gear 29 that meshes with the rack gear 30 of the rail portion 5.

The pinion gears 29 are provided on both right and left sides of the massage mechanism 2. That is, the pinion gears 29 are rotatably attached to both left and right end portions of the rotary shaft 13, rotate on the rack 30, and move in the front-rear direction. The pinion gear 29 is rotated by the rotational driving force of the rotary shaft 13, but is also decelerated to a predetermined speed by the speed change mechanism 31.

The transmission mechanism 31 is provided inside the pinion gear 29 and is provided at each of the left and right ends of the rotary shaft 13. The transmission mechanism 31 is housed in a gear case 32 provided in the base 8. The transmission mechanism 31 includes a 1 st gear 33, a driven shaft 34, a 2 nd gear 35, a 3 rd gear 36, a 4 th gear 37, and the like.

The 1 st gears 33 are rotatably attached to both right and left end portions of the rotary shaft 13. The 1 st gear 33 is engaged with the 2 nd gear 35 provided in front. The 2 nd gear 35 is rotatably attached to the driven shaft 34. The driven shaft 34 is provided in parallel (in the left-right direction) in front of the rotary shaft 13.

A 3 rd gear 36 is provided on the outer side of the 2 nd gear 35. The 3 rd gear 36 is rotatably attached to the driven shaft 34. That is, the 2 nd gear 35 and the 3 rd gear 36 are provided adjacently. The 3 rd gear 36 is engaged with the 4 th gear 37 provided at the rear.

The 4 th gear 37 is disposed outside the 1 st gear 33 and is rotatably attached to the rotary shaft 13. The 4 th gear 37 and the pinion gear 29 of the present embodiment are integrally formed. That is, the pinion 29 and the 4 th gear 37 rotate integrally.

I.e. the rotational driving force of the rotation shaft 13 is decelerated to a predetermined speed via the 1-second gear 33-2-3-4-gear 36-4-wheel 37 (speed change mechanism 31) and the pinion 29 is rotated to travel in the forward-backward direction on the rack 30. Thereby, the massage mechanism 2 can move in the front-rear direction along the guide rail portion 5.

Therefore, the massage mechanism 2 is guided and moved in the front-rear direction by the guide rail portion 5 (moving mechanism 15), and presses and massages the treatment portion from the hip T to the leg back B of the user U from the lower side to the upper side.

However, the rail portion 5 (rack 30) is formed in a shape with one side inclined downward. The rail portion 5 (rack 30) of the present embodiment has a shape that hangs down toward the front. That is, the rail portion 5 (rack 30) is an arc-shaped rail having a tip end side bent downward. Accordingly, the 1 st guide groove 6 and the 2 nd guide groove 7 are provided as arcuate rails on which the tip ends thereof are bent.

The guide rail portion 5 (rack 30), the 1 st guide groove 6, and the 2 nd guide groove 7 are provided as arc rails inclined forward and downward at the same inclination, and a space for accommodating the massage mechanism 2 is formed below the front portion of the support frame 3 (frame).

That is, of the internal space formed between the pair of right and left 1 st frame members 3a, the lower space on the front side of the rail portion 5 (rack 30) serves as the housing area S of the massage mechanism 2.

An inclined portion 38 that inclines downward as it goes forward is provided on the front end side of the guide rail portion 5 (rack 30). The position of the inclined portion 38 (the position where downward inclination starts (the starting point of the bending)) is preferably such that the rail portion 5 (the rack 30) is inclined from the front end of the 1 st frame member 3a to the left or right of the length of the 1 st frame member 3a (the support frame 3) in the front-rear direction.

The amount of lowering of the inclined portion 38 (the amount of movement in the vertical direction) is preferably at least about half the outer diameter of the treatment tool 9, and more preferably the maximum width is about the same as the outer diameter of the treatment tool 9. That is, the amount of lowering or the inclination angle of the inclined portion 38 may be set to such an amount of movement and an inclination angle that the treatment implement 9 is in a non-protruding state located below the upper edge of the support frame 3 (1 st frame member 3 a) in a side view.

Similarly, the 1 st guide groove 6 is also provided with an inclined portion 39 inclined downward at the same angle as the inclined portion 38. Furthermore, the 2 nd guide groove 7 is also provided with an inclined portion 40 inclined downward at the same angle as the inclined portion 38. That is, the front of the inclined portion 38-40 serves as the housing area S of the massage mechanism 2. The housing section S can house the massage mechanism 2 completely at the lower side.

The inclined portion 39 of the 1 st guide groove 6 and the inclined portion 40 of the 2 nd guide groove 7 may be inclined at the same angle as the inclined portion 38 so that the massage mechanism 2 can be lowered while maintaining a horizontal state, and a position (starting point of bending) at which the downward inclination is started may be determined.

As described above, by providing the inclined portion 38 in the guide rail portion 5 (rack 30), providing the inclined portion 39 having the same inclination angle, the same lowering amount, and the like as the inclined portion 38 in the 1 st guide groove 6, and providing the inclined portion 40 in the 2 nd guide groove 7 in the same manner as described above, the massage mechanism 2 can be moved to the storage area S provided in the front lower portion of the guide rail portion 5 while being moved obliquely downward forward while maintaining the horizontal state.

For example, when the pinion 29 is moved forward on the rack 30 (the guide rail portion 5) and moved toward the lower end (the end) of the inclined portion 38, the 1 st roller member 44 (described later in detail) traveling in the 1 st guide groove 6 moves toward the lower end (the end) of the inclined portion 39, and the 2 nd roller member 45 (described later in detail) traveling in the 2 nd guide groove 7 moves toward the lower end (the end) of the inclined portion 40, so that the massage mechanism 2 descends obliquely downward in front of the support frame 3 and moves toward the storage area S while maintaining a horizontal state.

When the massage body 10 is moved downward by the protrusion/retraction switching unit 14, the treatment tool 9 is positioned below the upper edge of the 1 st frame member 3a (support frame 3) in a side view and is in a non-protruding state (see fig. 2 or fig. 7 (a)).

This enables the massage mechanism 2 to be reliably stored in the storage area S in the support frame 3. Further, by providing the storage area S in which the massage mechanism 2 is completely stored on the lower side, the seating feeling of the user U is improved when the user U sits on the massage device 1.

In the present embodiment, the storage area S of the massage mechanism 2 is preferably provided at the front portion of the support frame 3. However, the housing section S may be provided at the rear of the support frame 3.

On the other hand, a rail recess 41 recessed downward is formed on the rear side of the rack 30 (rail portion 5). The rail recess 41 runs backward on the rack 30 via the pinion 29, and when the massage mechanism 2 is moved backward, the treatment tool 9 is moved downward and temporarily separated from the treatment portion. That is, the rail recess 41 temporarily pulls down the position of the treatment members 9 to a position below the upper edge of the support frame 3.

The rail recess 41 is recessed so that the rear portion side of the rack 30 (the guide rail portion 5) is curved downward in an arc shape. That is, the rack 30 is formed in a curved shape with the rear portion bulging downward.

Similarly, a guide recess 42 that is recessed downward is formed in the 1 st guide groove 6 provided adjacent to (in a communicating state with) the guide rail portion 5 at the same position as the guide rail portion 5. That is, the 1 st guide groove 6 is provided with a guide recess 42 bent downward in the rail corresponding to the rail recess 41.

By providing the track concave portion 41 in the rack 30 (the guide rail portion 5) and the guide concave portion 42 in the 1 st guide groove 6, when the user U sits on the massage apparatus 1 and performs pressing massage on the treatment portions such as the buttocks T, the treatment members 9 can be prevented from touching the bone portions (the ischial bones) protruding downward inside the buttocks T. That is, the feeling of use against the discomfort of the user U, such as pain caused by the treatment tool 9 pushing against the ischial bones, can be suppressed.

Further, the massage device 1 of the present embodiment is provided with a posture holding mechanism 43 for holding the posture of the massage mechanism 2 moving in the front-rear direction in a stable posture (horizontal posture). That is, the posture maintaining mechanism 43 supports the massage mechanism 2 at a plurality of points in order to stabilize the posture of the massage mechanism 2 moving in the front-rear direction.

As shown in fig. 1-5 and the like, the posture maintaining mechanism 43 includes a 1 st guide groove 6 formed in the 1 st frame member 3a, a 1 st roller member 44 (a 1 st moving body) traveling in the 1 st guide groove 6, a 2 nd guide groove 7 formed above the 1 st guide groove 6, and a 2 nd roller member 45 (a 2 nd moving body) traveling in the 2 nd guide groove 7.

The 1 st roller members 44 (1 st sliding members) are provided at both left and right ends of the rotary shaft 13, respectively. That is, the 1 st roller member 44 is disposed further outside the pinion gear 29 attached to the rotating shaft 13. The 1 st roller member 44 is slidably fitted in the 1 st guide groove 6 and advances in the front-rear direction.

The 1 st guide groove 6 is a long groove having the same track as the adjacent rack 30 (guide rail portion 5). That is, the 1 st guide groove 6 has a rail (inclined portion 39) and a horizontal rail, the front end side of the rail (inclined portion 39) is inclined downward toward the front, and the horizontal rail and the inclined rail communicate with each other and face rearward. Further, a guide recess 42 curved so as to gradually recess downward corresponding to the rail recess 41 is provided at the horizontal rail of the 1 st guide groove 6.

The 2 nd roller member 45 (2 nd sliding member) is provided in front of the 1 st roller member 44. The 2 nd roller member 45 is attached to a projecting piece 46 provided on the front end side of the base 8. The projecting piece 46 is a rod-like member projecting upward and outward in the right and left direction from the front end of the base 8. A 2 nd roller member 45 is provided at the tip of the projecting piece 46.

That is, the 2 nd roller member 45 is disposed on the upper front side as viewed from the 1 st roller member 44. The 2 nd roller member 45 is slidably fitted in the 2 nd guide groove 7 and moves forward and backward.

The 2 nd guide groove 7 is a long groove having substantially the same track as the 1 st guide groove 6. The 2 nd guide groove 7 is arranged above and in front of the 1 st guide groove 6 with a distance. That is, the 2 nd guide groove 7 has a rail (inclined portion 40) inclined downward with the leading end side thereof directed forward, and a horizontal rail communicating with the inclined rail and directed rearward.

The inclined portion 40 of the 2 nd guide groove 7 is provided on the front upper side as viewed from the inclined portion 39 of the 1 st guide groove 6. Further, the curved rail corresponding to the rail recess 41 is not provided on the rear end side of the 2 nd guide groove 7.

The massage mechanism 2 is kept in a stable posture (horizontal posture) when moving in the front-rear direction by the 1 st roller member 44 slidably fitted into the 1 st guide groove 6 in the front-rear direction and the 2 nd roller member 45 slidably fitted into the 2 nd guide groove 7 in the front-rear direction.

[ operating modes ]

Next, an operation mode of the massage device 1 of the present invention will be described with reference to the drawings.

Fig. 7 shows the operation of the massage mechanism 2 moving from the front end storage area S to the rear end in this order from above.

Fig. 7 (a) shows a state where the massage mechanism 2 is located in the storage area S on the front side of the guide rail portion 5. Fig. 7 (b) shows a state in which the treatment tools 9 protrude upward and press-massage the treatment site.

Fig. 7 (c) shows a case where the pinion 29 is located in the rail recess 41 and the 1 st roller member 44 is located in the guide recess 42 of the 1 st guide groove 6. Fig. 7 (d) shows a case where the treatment tool 9 is positioned at the uppermost position on the rear side of the rail portion 5.

In the operating condition shown in fig. 7 (a), when the pinion 29 is positioned at the tip of the inclined portion 38 of the rack 30 (guide rail portion 5), the 1 st roller member 44 is positioned at the inclined portion 39 of the 1 st guide groove 6, and the 2 nd roller member 45 is positioned at the inclined portion 40 of the 2 nd guide groove 7.

That is, the massage mechanism 2 is located in the housing area S provided on the front side of the guide rail portion 5. At this time, the massage body 10 is positioned at the lowermost side by the protrusion/retraction switching portion 14 (see the height L (lowermost position) of fig. 7 (a)). Thereby, the treatment members 9 are also located at the lowermost side. The massage mechanism 2 is controlled as described above.

When the massage mechanism 2 moves from the rear to the front, the massage mechanism 2 is lowered and stored in the storage area S, and the treatment tools 9 are positioned below the upper edge of the 1 st frame member 3a (support frame 3).

When the rotary shaft 13 is rotated by the rotational driving force from the driving motor 12, the pinion 29 travels on the rack 30 of the guide rail portion 5 from the inclined portion 38 to the rear. Then, the 1 st roller member 44 moves rearward from the inclined portion 39 of the 1 st guide groove 6. Then, the 2 nd roller member 45 moves rearward from the inclined portion 40 of the 2 nd guide groove 7.

At this time, the massage mechanism 2 is raised in a horizontal posture by the posture maintaining mechanism 43 composed of the 1 st roller member 44, the 2 nd roller member 45, and the like. That is, the massage body 10 is raised, and the treatment members 9 are turned toward the upper edge of the support frame 3.

When the pinion 29 moves to the horizontal portion of the rack 30 (the guide rail portion 5) beyond the inclined portion 38, the 1 st roller member 44 moves to the horizontal portion (the horizontal rail) of the 1 st guide groove 6 beyond the inclined portion 39. Similarly, the 2 nd roller member 45 moves over the inclined portion 40 to the horizontal portion (horizontal rail) of the 2 nd guide groove 7. The massage mechanism 2 is changed to the posture shown in fig. 7 (b).

In the operating condition shown in fig. 7 (b), the pinion 29 travels on the horizontal portion (horizontal rail) of the rack 30 (guide rail portion 5) by the rotation of the rotary shaft 13. At this time, the 1 st roller member 44 is positioned near the middle part in the front-rear direction of the 1 st guide groove 6 (horizontal rail), and the 2 nd roller member 45 is positioned near the middle part in the front-rear direction of the 2 nd guide groove 7 (horizontal rail).

In this way, the posture maintaining mechanism 43 constituted by the 1 st roller member 44, the 2 nd roller member 45, and the like is maintained at a constant (horizontal posture), and the posture of the massage mechanism 2 during movement is not changed.

In this state, the treatment members 9 are changed to a state of protruding upward from the upper edge of the support frame 3. Therefore, the protruding treatment members 9 can push and massage the treatment portion of the user U tangentially.

The treatment members 9 on the front side and the treatment members 9 on the rear side move rearward while maintaining the substantially same horizontal posture height. When the massage body 10 is moved forward and backward in this state, the massage body 10 is in an unrestrained state (free state) while rotating around the axis of the rotating shaft 13, and therefore can be smoothly moved in the forward and backward directions along the shape from the leg back B to the hip T of the user U. Therefore, when the treatment tool 9 moves forward and backward, the treatment portion of the user U can be excellently pressed and massaged.

That is, the massage body 10 repeats the protrusion/retraction movement in the vertical direction by the switching operation of the protrusion/retraction switching unit 14 (the rotation movement of the rotation shaft 13 is switched to the protrusion/retraction movement in the vertical direction), and the treatment implement 9 repeats the wave-like movement because it moves in the vertical direction while moving in the forward and backward directions.

That is, the treatment tool 9 moving forward and backward is repeatedly pressed upward at a constant interval and pulled downward. This enables excellent pressing massage to be performed on the region (treatment site) from the leg back B to the hip T of the user U.

When the pinion 29 moves to the track recess 41 of the rack 30 (the rail portion 5), the massage mechanism 2 changes to the posture as shown in fig. 7 (c).

In the operating condition shown in fig. 7 (c), when the pinion 29 travels on the rack 30 (horizontal rail) and enters the rail recess 41, the 1 st roller member 44 adjacent to the pinion 29 enters the guide recess 42 provided in the 1 st guide groove 6. In addition, the 2 nd roller member 45 does not change in height because it is positioned on the 2 nd guide groove 7 which is linear (horizontal rail).

That is, the pinion 29 located on the rear side enters the rail recess 41 and descends, and at the same time, the 1 st roller member 44 enters the guide recess 42 and descends. On the other hand, the 2 nd roller member 45 positioned on the front side advances straight rearward, and therefore maintains a high position. Thereby, the massage mechanism 2 is in a state of being tilted backward.

At this time, the treatment tool 9 on the front side slightly protrudes above the upper edge of the support frame 3. On the other hand, the treatment members 9 on the rear side are pulled down completely from the upper edge of the support frame 3 to below.

That is, since only the treatment devices 9 on the rear side can be lowered to a position below the upper edge of the support frame 3, the treatment devices 9 on the rear side can be prevented from hitting the ischial bones of the user U. When the massage mechanism 2 further moves backward, the posture thereof changes to the posture shown in fig. 7 (d).

In the operating condition shown in fig. 7 (d), the pinion 29 moves rearward from the rail recess 41 and reaches the rear end of the guide rail portion 5. At this time, the 1 st roller member 44 moves backward from the guide recess 42 to reach the rear end of the 1 st guide groove 6. The 2 nd roller member 45 also moves straight rearward and reaches the rear end of the 2 nd guide groove 7.

The posture of the massage mechanism 2 is kept constant (horizontal posture) by the posture holding mechanism 43 constituted by the 1 st roller member 44, the 2 nd roller member 45 and the like, and does not change. In this state, the treatment members 9 are changed to a state of protruding from the upper edge of the support frame 3 to the uppermost side.

That is, when the massage body 10 reaches the rear side (the other side) of the guide rail portion 5 belonging to the opposite side of the storage section S, the massage body 10 is positioned uppermost by the protrusion/retraction switching portion 14 (see the height H (highest position) of fig. 7 d). Thereby, the treatment members 9 are raised to the highest position. The massage mechanism 2 may be controlled as described above. Thus, the protruding treatment members 9 can press and massage along the shape of the buttocks T of the user U.

Further, the massage body 10 does not have to be positioned uppermost at the rear side of the rail portion 5, and for example, it is sufficient to be positioned at a position where it rises corresponding to the eccentricity of the hub member 27, and there is no problem of increasing 2/3 of the eccentricity of the hub member 27.

In this state, when the massage body 10 is moved rearward, the massage body 10 is rotated about the axis of the rotation shaft 13, but is in an unrestricted state (free state), and therefore can be smoothly moved along the shape of the hip T of the user U. Therefore, when the treatment tool 9 is moved rearward, the user U can be well massaged by pushing the hip T.

However, the massage mechanism 2 may be stored in the reverse order described above. That is, the massage mechanism 2 can be moved in the order of (d) -a of fig. 7. Thus, when the massage mechanism 2 moves from the rear to the front, it is lowered and stored in the storage area S, and the treatment tools 9 are positioned below the upper edge of the 1 st frame member 3a (support frame 3).

When the massage mechanism 2 is in the storage area S, the control unit of the massage device 1 may perform the following control: the eccentric position of the eccentric boss 27 is positioned at the lowermost position L, and the treatment tool 14 is lowered into the support frame 3 without being projected upward.

Further, when the massage mechanism 2 moves in the front-rear direction, the control unit of the massage device 1 can repeatedly perform control for raising and lowering the treatment applying members 14.

On the other hand, when the massage mechanism 2 is moved to the rear end, the control unit of the massage device 1 may perform control to set the eccentric position of the eccentric boss 27 to the highest position H and to project the treatment implement 14 to the uppermost position.

Thus, the user U can be massaged reliably at the region (treatment portion) from the leg back B to the hip T, and the massage mechanism 2 can be reliably housed in the housing area S in the support frame 3.

It is preferable that the position detection unit 47 for detecting the position of the massage mechanism 2 be used for the stop position of the massage mechanism 2 during the forward and backward movement (for example, the stop of the drive unit 11 in the storage area S).

The position detector 47 is preferably a sensor such as a limit switch for detecting a stop position of the massage mechanism 2 in the forward and backward movement.

Further, the position detection unit 47 for detecting the position of the massage mechanism 2 is preferably used for a stop position of the massage body 10 in the vertical protrusion/retraction (for example, rotation stop of the protrusion/retraction conversion unit 14 at the lowermost position of the treatment implement 9 in the storage area S, rotation stop of the protrusion/retraction conversion unit 14 at the uppermost position of the rear end portion of the treatment implement 9, and the like).

The position detecting unit 47 is preferably a sensor such as a rotary encoder that detects the rotation angle of the protrusion/retraction converting unit 14 when detecting, for example, the stop position in the up-and-down protrusion/retraction of the massage body 10.

As described above, according to the massage device 1 of the present invention, it is possible to effectively massage the treatment site from the leg back B to the hip T of the user U, and it is possible to reliably store the massage mechanism 2 in the support frame 3 without protruding the treatment implement 9 and the like from the upper edge of the support frame 3, while being a compact and compact massage mechanism 2.

In the massage device 1 of the present invention, the massage mechanism 2 can be completely stored in the lower storage area S, and thus, when the user U sits on the massage device 1, the user U can be more comfortable to sit on.

As shown in fig. 7 and the like, in the present embodiment, the main body of the massage mechanism 2 housing the drive motor 12 and the rotary shaft 13 is always positioned below the upper end of the 1 st frame member 3a. That is, the massage mechanism 2 of the present embodiment does not have the rotation shaft or the like greatly raised from the upper edge of the unit as in fig. 15 or the like of japanese patent application laid-open No. 2013-248144 (patent document 1). Further, the number of components such as a mechanism for raising the massage mechanism does not need to be increased.

In addition, the embodiments disclosed herein are to be considered in all respects as illustrative and not restrictive.

In particular, matters not explicitly described in the embodiments disclosed herein, such as operation conditions, and the size and weight of the components, are assumed to be those that can be easily estimated by those skilled in the art without departing from the scope of the general practice of the art.

For example, the length of the arm members 24 and 25 (massage bodies 10) provided in the massage mechanism 2, the degree of eccentricity of the massage bodies 10 with respect to the rotation shaft 13, the distance separating the massage bodies 10 positioned on the left and right sides, and the like can be appropriately changed according to the treatment range. Further, the hub member 27 may be inclined, and the inclination angle thereof may be appropriately changed.

When the massage mechanism 2 is moved forward and backward, the massage mechanism may be controlled to perform the pushing massage while keeping the treatment instrument 9 pushed upward (linearly moved without pulling down the treatment instrument 9 from the leg back B (front) to the hip T (rear) of the user U).

The massage apparatus 1 of the present invention may be provided with a plurality of drive motors 12. When the treatment tool 9 is formed as a ball, for example, it can be attached to the end of the massage body 10 via a biasing means such as a spring because it supports the hip T by distributing the load. The massage device 1 may further include a width adjustment mechanism for varying the distance between the pair of left and right massage members 10.

The massage device 1 of the present invention may be mounted in a seat portion of a fixed chair-type massage machine. The massage device 1 of the present invention may be mounted in a seat portion of a portable chair-type massage machine.
