Description

Massage device

Technical Field

The application relates to a massage device.

Background

Japanese patent application laid-open No. 2008-22892 (hereinafter, referred to as patent document 1) filed by the applicant of the present application discloses a technique for swinging a seat main body by an airbag or the like. International publication No. 2008/133066 (hereinafter, referred to as patent document 2) discloses a technique for reciprocating a seat by rotation of a motor.

Patent document 1: japanese patent laid-open No. 2008-22892

Patent document 2: international publication No. 2008/133066

In the massage device, a special action is required in the same way as a massage action by a human hand. For example, it is required to perform a smoothing operation such as an operation of making a fluctuation (referred to as a 1/f fluctuation) in which the spectral density is inversely proportional to the frequency.

Disclosure of Invention

In this regard, in patent document 1, it is necessary to switch the airbag at the time of performing the reciprocation, or if an actuator that expands and contracts by a motor is used, it is necessary to reverse the rotation, and thus the operation is stopped, or the torque of the motor immediately after the reverse rotation is increased, and the operation speed is lowered, so that the discontinuous operation is performed, and for example, smooth operation such as 1/f fluctuation is prevented. Further, in patent document 2, since the reciprocating movement of the seat portion includes a component of up-and-down movement (see fig. 28 to 30 in particular), there is a case where the gravity load hinders the operation of the seat portion intended by the manufacturer. In particular, if the motion of the seat portion intended by the manufacturer is smooth such as 1/f fluctuation, the motion may be hindered. Accordingly, an object of the present invention is to provide a massage device that can perform a motion intended by a manufacturer on a sitting portion that supports buttocks.

According to one embodiment, a massage device includes: a main body portion; a sitting portion for supporting buttocks; and a moving member fixed to the seat portion and supporting the seat portion so as to be movable with respect to the main body portion, the moving member being supported so as to be freely reciprocatingly movable with respect to the main body portion by rolling contact or sliding contact with the main body portion, the massage device further comprising: a motor; and a conversion unit that converts the rotation of the motor in one direction into the reciprocating movement of the moving member via the eccentric cam.

Further details are described as embodiments described below.

Detailed Description

< 1. Outline of massaging device >)

(1) The massage device according to the embodiment comprises: a main body portion; a sitting portion for supporting buttocks; and a moving member fixed to the seat portion and supporting the seat portion so as to be movable with respect to the main body portion, the moving member being supported so as to be freely reciprocatingly movable with respect to the main body portion by rolling contact or sliding contact with the main body portion, the massage device further comprising: a motor; and a conversion unit that converts the rotation of the motor in one direction into the reciprocating movement of the moving member via the eccentric cam.

By supporting the moving member so as to be capable of freely reciprocating relative to the main body by rolling contact or sliding contact with the main body, the interference of gravity load on operation can be reduced. The conversion unit converts the unidirectional rotation of the motor into the reciprocating movement of the moving member via the eccentric cam, thereby converting the unidirectional rotation of the motor into the continuous reciprocating movement. Thus, the motor can be continuously rotated in one direction to realize reciprocating movement without reversing or stopping the rotation between the forward and return paths. As a result, discontinuous operation due to operation stop, operation speed reduction, or the like can be avoided, and smooth operation such as 1/f fluctuation can be realized, for example.

(2) Preferably, the massage device further includes a roller at a position on one of the moving member and the main body portion, which is in rolling contact with the other. Thereby, the moving member can be in rolling contact or sliding contact with the main body.

(3) Preferably, the eccentric cam rotates about an axis orthogonal to the horizontal plane, and the conversion unit includes a conversion member that converts rotation of the eccentric cam into reciprocal movement in the horizontal plane. The rotation of the eccentric cam in the horizontal plane can be converted into the reciprocating movement in the horizontal plane by the conversion member.

(4) Preferably, the conversion unit includes a speed reducer that is disposed between the motor and the eccentric cam and that reduces the rotation of the motor. Thereby, appropriate rotation is applied to the eccentric cam.

(5) Preferably, the massage device further includes a roller disposed at a position of the moving member in rolling contact with the main body, the switching unit includes a speed reducer disposed between the motor and the eccentric cam, the speed reducer reducing rotation of the motor, the surface of the main body on the moving member side includes a region in which the roller contacts and rolls, the motor and the speed reducer are disposed on the surface of the main body, and the speed reducer is disposed on the surface of the main body on the moving member side and the back surface thereof in a dispersed manner. Thus, a region for contact with the moving member can be ensured on the surface of the main body portion on the side facing the moving member.

(6) Preferably, the massage device further includes a guide that reciprocates, and the guide includes: a guide portion provided on either one of the moving member and the main body portion; and a guided portion provided on the other and moving along the guide portion. Thus, the moving member can reciprocate in an appropriate direction.

(7) Preferably, the massage device further includes a controller that controls driving of the motor, and the control includes control of driving the motor so that the motion of the seat becomes a fluctuation in which the spectral density is inversely proportional to the frequency. This enables a user sitting on the sitting portion to perform a 1/f fluctuation massage operation.

< 2. Example of massaging device >)

Fig. 1 is a schematic configuration diagram of a massage device 100 according to the present embodiment. The massage apparatus 100 is an apparatus for providing massage by stimulating the body of a user, and may be a chair type (i.e., a massage chair) for sitting and using by a user, for example. In the following examples, the massage device 100 is considered a massage chair. In the following description, the right and left, up and down, and front and back refer to the right and left, up and down, and front and back when viewed from a user sitting on the massage device 100.

Referring to fig. 1, the massage apparatus 100 mainly includes: a seat 2 for a user to sit on; a backrest 3 provided at the rear of the seat 2 so as to be tiltable backward and on which a user leans; a foot rest 4 provided in the front of the seat 2 so as to be capable of swinging up and down, and supporting the lower limbs of the user; a pillow part 5 provided on the upper front surface of the backrest part 3 and supporting the head and/or neck of the user; elbow rest parts 6 (arm frames) provided on both left and right sides of the seat part 2; and side wall portions 7 provided on both left and right sides of the backrest portion 3.

The seat portion 2, the backrest portion 3, the foot rest 4, the pillow portion 5, the armrest portion 6, and the side wall portion 7 function as a body support portion that supports a part of the body (i.e., a body part) of the user. The upper surface of the seat portion 2, the user-side surface of the backrest portion 3, the upper surface of the armrest portion 6, and the like constitute a body support surface that supports a portion of the body (i.e., a body part) of the user.

A plurality of massage units, which are operation mechanisms for performing massage operations on the body of the user, are provided at each of the body support sections 2 to 7. The massage unit is driven by the driving mechanism, and performs massage accompanied by pressing on the body part supported by the body support.

The seat 2 is provided with a seat massage unit 2A for performing a rocking motion on the buttocks. The rocking motion is a motion for continuously moving the buttocks of the user sitting on the seat 2 to the left and right, and is a reciprocating motion of the seat 2 in the left and right direction. The shaking motion may be performed at a predetermined speed. The predetermined speed may be, for example, a so-called 1/f speed which is a fluctuation of the spectral density inversely proportional to the frequency. 1/f is a speed (in other words, a change or action that exists in nature and cannot be predicted) that is mixed with a regular speed and an irregular speed. Thus, a comfortable swing can be given to a seated user. As another example, the predetermined speed may be a constant speed. This can give a stable feeling to the seated user.

The feeling of rhythm at the speed 1/f may be fast or slow. The rhythm sense here is a cycle of the reciprocating movement (a group of right to left and left to right) of the seat 2. In more detail, the following moves as one cycle: a movement (1 st movement) of moving rightward and then leftward, and returning to the center, based on the state where the seat 2 is located at the center; and a movement (movement 2) of moving leftward and rightward, and returning to the center, based on the state where the seat 2 is located at the center.

Thus, 1/f can be achieved by changing the speeds of the 1 st movement and the 2 nd movement. And 1/f can be achieved by changing the speed at a certain moment of the 1 st movement and/or the 2 nd movement.

The change of the speed can be achieved by adjusting the driving amount of the motor. The feeling of rhythm of 1 speed 1/f may be set to be 1 time in one cycle, or the feeling of rhythm of 1/f may be set to be 3 times in one cycle. By changing the number of occurrences in one cycle (changing the feeling of rhythm), even if the speeds 1/f are the same, it is possible to realize a speed 1/f with a fast feeling of rhythm and a speed 1/f with a slow feeling of rhythm. Thus, the speed 1/f can be varied.

For example, if a massage package is intended for vitality, it is preferable to include 1/f of the speed of a rapid feeling of rhythm a plurality of times in one cycle. Specifically, the driving amount of the motor may be adjusted to control the speeds of the 1 st movement and the 2 nd movement so that the entire 1 st movement becomes 1/f of the speed with a fast feeling of rhythm, or the speed of the 2 nd movement may be controlled to become 1/f of the speed with a fast feeling of rhythm. Thus, the user can be made active.

Further, in order to provide a massage package for relaxation, it is preferable to include a speed 1/f at which the feeling of rhythm is slow a plurality of times in one cycle. Specifically, the driving amount of the motor may be adjusted to control the speeds of the 1 st movement and the 2 nd movement so that the 1 st movement as a whole becomes the speed 1/f at which the feeling of rhythm is slow, or the speed of the 2 nd movement at a certain time may be controlled so that the feeling of rhythm is slow 1/f. In this way, the user can be relaxed.

The number of times and the time of the speed 1/f having a fast feeling of rhythm and the speed 1/f having a slow feeling of rhythm are only examples, and the present invention is not limited thereto. In addition to the above, 1/f of various speeds may be combined according to the purpose of each massage package.

The backrest part 3 is mainly provided with a mechanical massage unit 8 for performing a massage action on the neck to waist. Leg massage units 4A, 4B for mainly massaging the lower leg and the sole of the foot are provided on the left and right sides of the foot rest 4. The armrest portion 6 is provided with arm massage units 6A, 6B on the left and right sides for performing a massage operation mainly on the arms. The side wall portion 7 is provided with shoulder massage means 7A, 7B on the left and right sides for mainly performing a massage operation on a position called "shoulder" on the side of the shoulder portion to the upper arm portion. A pump unit 9 is provided below the seat 2.

Fig. 2 is a schematic exploded perspective view of the seat massage unit 2A. Referring to fig. 2, the seat massage unit 2A includes a seat portion 20, a moving member 21, and a main body portion 22. The seat portion 20, the moving member 21, and the body portion 22 are overlapped in order from the body of the massage device 100 toward the user sitting on the seat portion 2. That is, the moving member 21 is overlapped to be positioned below the seat portion 20, and the main body portion 22 is positioned below the moving member 21.

The seat 20 is disposed at a position closest to a user seated on the seat 2, and supports the buttocks of the user. The seat portion 20 is provided with edge portions 201 on the left and right sides to restrict the buttocks of the user from the left and right directions. Preferably, a pressing member is disposed inside the rim 201. The pressing members are, for example, air bags 202R, 202L. The air bags 202R and 202L are air bags inflated and deflated by air supply and air discharge, and are examples of pressing members for pressing a body part of a user by air supply and air discharge. In this way, the user can swing while the hip is in close contact with the seat 20 by using the airbags 202R and 202L during the swinging operation.

The airbags 202R and 202L can be inflated and deflated independently from each other. In this way, the inflation and deflation of the airbags 202R, 202L can be combined into a normal rocking operation, and thus various rocking operations can be realized in which the movement of the seat portion 20 and the inflation and deflation of the airbags 202R, 202L are linked. The operation mode of the shaking operation will be described later.

The moving member 21 is disposed below the seat portion 20, and the seat portion 20 is fixed to the moving member 21. Thereby, the seat portion 20 moves together with the moving member 21. That is, the moving member 21 supports the seat portion 20 so as to be movable with respect to the main body portion 22.

The main body 22 is a structural part of the massage device 100 serving as a base of the seat 2. The moving member 21 is disposed above the main body 22, and is supported so as to be movable back and forth with respect to the main body 22. Therefore, the seat portion 20 fixed to the moving member 21 reciprocates with respect to the main body portion 22 along with the reciprocation of the moving member 21.

Fig. 3 is a schematic diagram showing the structure of the moving member 21, wherein (a) is a plan view, (B) is a front view, and (C) is a bottom view. Fig. 4 is a schematic diagram showing the structure of the main body 22, in which (a) is a plan view, (B) is a front view, and (C) is a bottom view. Fig. 5 is a schematic diagram showing a positional relationship between the moving member 21 and the main body 22.

Referring to fig. 3, the moving member 21 has a top plate 211, and the top plate 211 is provided with openings 212 and 213. A seat portion 20 is fixed to the upper surface 211A side of the top plate 211. In other words, the surface of the top plate 211 on the seat portion 20 side is the upper surface 211A. The upper surface 211A is the side facing the user, and the lower surface 211B is the back side thereof. By providing the openings 212 and 213, when the moving member 21 is disposed to overlap the main body 22 as shown in fig. 5, a hand or a tool can be inserted from the openings 212 and 213, and maintenance of the structure between the moving member 21 and the main body 22 is facilitated.

The lower surface 211B of the top plate 211 is provided with a fixing portion 217. The fixing portion 217 is for fixing a switching member 223 attached to an eccentric cam 222 of the main body 22 described later. As an example, the fixing portion 217 is a convex downward member.

The lower surface 211B of the top plate 211 is provided with a contact member that contacts the top plate 221 of the main body portion 22. The contact member is a member that makes rolling contact or sliding contact with the top plate 221 of the main body 22, and the roller 216 is an example. The lower surface 211B of the top plate 211 is provided with a roller 216 rotating in the left-right direction as the traveling direction. As an example, four rollers 216 are disposed on the front left and right sides and the rear left and right sides of the top plate 211.

Side surfaces 214 are provided on the front and rear sides of the top plate 211. The side surface 214 is provided with a long hole 215 extending in the left-right direction with respect to the longitudinal direction. Preferably, two (four in total) elongated holes 215 are provided on each of the left and right side surfaces 214 on the front and rear sides. The long hole 215 is an example of a guide portion included in the guide 23, and constitutes the guide 23 together with a pin 228, which will be described later, as an example of a guided portion.

Referring to fig. 4, the main body 22 has a top plate 221. As shown in fig. 5, on the upper surface 221A side of the top plate 221, the moving member 21 is supported so as to be freely reciprocatingly movable in the left-right direction. In other words, the surface of the top plate 221 on the moving member 21 side is the upper surface 221A.

The lower surface 221B of the top plate 221 is provided with a motor M (more specifically, a main body portion of the motor M) that rotates in one direction about a rotation axis MA. The eccentric cam 222 is disposed on the upper surface 221A of the top plate 221 such that the rotation axis 222A is orthogonal to the horizontal plane.

The rotation of the motor M is applied to the eccentric cam 222 via a speed reducer. As an example of the speed reducer, the main body 22 includes gears 225A, 225B, 229. That is, the rotation of the motor M is sequentially applied to the gears 225A, 225B, 229.

In detail, the motor M is configured such that the rotation axis MA protrudes more than the upper surface 221A. Rotation axis MA is connected to gear 225A via endless belt member 220 on upper surface 221A. Thus, when the rotation shaft MA rotates, power is transmitted to the gear 225A via the belt member 220.

The gear 225B is configured to mesh with the gear 225A on the lower surface 211B side. Gear 225A is rotated by the power generated by the rotation of rotation shaft MA, whereby gear 225B is also rotated. The gear 229 is configured to mesh with the gear 225B on the lower surface 211B side. The gear 225B rotates with the rotation of the gear 225A, whereby the gear 229 also rotates.

The number of teeth of gear 229 is greater than the number of teeth of gear 225A. Thereby, the rotation of the motor M transmitted to the gear 225A through the rotation shaft MA of the motor M is decelerated, so that appropriate rotation is applied Yu Pianxin to the cam 222. The gear 229 is arranged such that the rotation axis coincides with the rotation axis 222A of the eccentric cam 222. Accordingly, the eccentric cam 222 rotates with the rotation of the gear 229.

The eccentric cam 222 is connected to a conversion section. The conversion section includes a conversion member 223. The conversion member 223 has a 1 st mounting portion 222B and a 2 nd mounting portion 224. The conversion member 223 is a plate-like member long in the left-right direction, and the 1 st mounting portion 222B and the 2 nd mounting portion 224 are disposed near both ends.

The conversion member 223 is attached to the eccentric cam 222 via the 1 st attachment portion 222B. The 1 st mounting portion 222B mounts the conversion member 223 to the eccentric cam 222 in a manner allowing rotation. The 1 st mounting portion 222B is provided at a position eccentric from the rotation shaft 222A with respect to the eccentric cam 222. The conversion member 223 is attached to the fixed portion 217 of the moving member 21 by the 2 nd attachment portion 224. The 2 nd mounting portion 224 mounts the conversion member 223 to the fixing portion 217 in a manner allowing rotation.

Side surfaces 227 are provided on the front and rear sides of the top plate 221. The side 227 is provided with a pin 228. The pin 228 is an example of a guided portion included in the guide 23. The pin 228 is a protrusion protruding outward from the side face 227. The pin 228 has a smaller size and shape in cross section than the long hole 215 provided in the side face 214 of the moving member 21. The pin 228 is provided at a position corresponding to the long hole 215, and the long hole 215 is provided on the side surface 214 of the moving member 21. In the example of fig. 3 and 4, two (four) elongated holes 215 and pins 228 are provided on the front and rear side surfaces, respectively, on the left and right sides.

As shown in fig. 5, the moving member 21 is disposed so as to overlap the main body 22 such that the front and rear side surfaces 214 are located outside the front and rear side surfaces 227 of the main body 22. Therefore, the length H2 of the top plate 221 of the main body portion 22 in the front-rear direction is slightly shorter than the length H1 of the top plate 211 of the moving member 21 in the front-rear direction.

When the moving member 21 is disposed on the main body 22 in an overlapping manner, the roller 216 provided on the lower surface 211B of the top plate 211 of the moving member 21 contacts the upper surface 221A of the top plate 221 of the main body 22. The roller 216 is in rolling or sliding contact with the upper surface 221A of the top plate 221. This reduces the interference of the gravity load with the operation between the moving member 21 and the main body 22.

The roller 216 is provided for bringing the moving member 21 into rolling contact or sliding contact with the main body 22. Therefore, as another example, the roller 216 may be provided on the upper surface 221A of the top plate 221 of the main body 22. As another example, the rollers 216 may be provided so as to be dispersed on the lower surface 211B of the top plate 211 of the moving member 21 and the upper surface 221A of the top plate 221 of the main body 22.

When the moving member 21 is disposed to overlap the main body 22, the pins 228 provided on the side faces 227 are inserted into the long holes 215 of the side faces 214 of the moving member 21. The length of the pin 228 from the side face 227 to the outside is longer than the thickness of the long hole 215 of the moving member 21. Therefore, the moving member 21 can move within the range of the long hole 215 by the pin 228 provided in the main body portion 22. That is, the moving member 21 moves along the long hole 215 as an example of the guide portion by the pin 228 as an example of the guided portion included in the guide 23. That is, the guide 23 (the pin 228 and the long hole 215) can restrict the direction of the reciprocating movement of the moving member 21.

When the moving member 21 is disposed on the main body 22 in an overlapping manner, the outer surfaces of the front and rear side surfaces 227 of the main body 22 are respectively in contact with the inner surfaces of the front and rear side surfaces 214 of the moving member 21. Since the main body 22 is structured as the massage device 100, its position is fixed with respect to the massage device 100. Therefore, the movement of the moving member 21 in the front-rear direction will not be allowed.

The conversion member 223 is disposed in a horizontal plane. Thereby, the conversion unit converts the unidirectional rotation of the motor M into the reciprocal movement of the moving member 21 in the horizontal plane via the eccentric cam 222. Fig. 6 is a diagram for explaining a structure for converting rotation in one direction of the motor M into reciprocation of the moving member 21.

The 1 st mounting portion 222B of the switching member 223 moves in the rotation plane in accordance with the rotation of the eccentric cam 222. Since the eccentric cam 222 rotates about the rotation axis 222A orthogonal to the horizontal plane, the 1 st mounting portion 222B of the conversion member 223 moves in the horizontal plane. Specifically, referring to fig. 6, the eccentric cam 222 rotates R, and the 1 st mounting portion 222B moves from the position P1 to the position P2. The 1 st mounting portion 222B is located at a position eccentric from the rotation shaft 222A of the eccentric cam 222, and thus the 1 st mounting portion 222B moves forward by a distance L1 from the position P1 to the position P2 and moves rightward by a distance L2.

The conversion member 223 is connected to the fixed portion 217 of the moving member 21 by the 2 nd attachment portion 224 so as to be rotatable but not allowed to move in the rotation plane. The forward stress and the rightward stress generated by the movement of the 1 st mounting portion 222B are applied to the 2 nd mounting portion 224 via the switching member 223. However, since the movement of the moving member 21 in the front-rear direction is restricted by the guide 23, the movement of the 2 nd mounting portion 224 connected to the fixing portion 217 in the front-rear direction is restricted. As a result, the forward stress applied to the 2 nd mounting portion 224 is converted into rotation, and is moved rightward by the rightward stress by the distance L.

When the motor M is rotated repeatedly in one direction, the 1 st mounting portion 222B is rotated to apply a rightward stress to the 2 nd mounting portion 224 when the 1 st mounting portion 222B is rotated to a half of the 2 nd mounting portion 224, and applies a leftward stress when the motor M is rotated to a half of the 2 nd mounting portion. Therefore, by repeatedly rotating the motor M in one direction, the stress in the left-right direction can be repeatedly applied to the 2 nd mounting portion 224. As a result, the moving member 21 to which the fixed portion 217 is connected through the 2 nd attachment portion 224 can be repeatedly subjected to stress in the left-right direction.

Since the pin 228 of the main body 22 is inserted into the long hole 215 of the moving member 21, when a stress in the left-right direction is applied to the moving member 21, the moving member 21 can move in the longitudinal direction until the pin 228 comes into contact with the end of the long hole 215 in the left-right longitudinal direction. Referring to fig. 5, by repeatedly applying a stress in the left-right direction to the moving member 21, the moving member 21 disposed in the main body 22 is repeatedly moved rightward (a) and leftward (B) with respect to the main body 22 within a range of the length of the long hole 215 in the longitudinal direction. That is, the guide 23 constituted by the long hole 215 and the pin 228 guides the reciprocating movement of the moving member 21 in the left-right direction.

Since the seat portion 20 is fixed to the moving member 21, the seat portion 20 also reciprocates in association with the reciprocation of the moving member 21. Thereby, the seat massaging unit 2A can perform a rocking motion on the buttocks of the user sitting on the seat 2.

The moving member 21 reciprocates while being in rolling contact or sliding contact with the main body portion 22 by the roller 216. Therefore, the contact area 226 of the roller 216 needs to be provided on the upper surface 221A of the top plate 221 of the main body 22. In this regard, the gears 225A constituting the speed reducer are disposed on the upper surface 221A and the lower surface 221B of the top plate 221, the gears 225B are disposed on the lower surface 221B, and the gears 229 are disposed on the lower surface 221B so as to be dispersed from each other. The rotation shaft MA of the motor M is connected to the gear 225A via an endless belt member 220 on the upper surface 221A. The gear 225B is configured to mesh with the gear 225A on the lower surface 211B side. The gear 229 is configured to mesh with the gear 225B on the lower surface 211B side. Thereby, the contact region 226 can be secured on the upper surface 221A of the top plate 221 of the main body portion 22.

Since the conversion section including the conversion member 223 converts the unidirectional rotation of the motor M into the reciprocating movement, the unidirectional rotation of the motor M can be converted into the continuous reciprocating movement in the seat massage unit 2A. Thus, the motor M can be reciprocated by continuous rotation in one direction without reversing or stopping the rotation between the forward and reverse paths. As a result, discontinuous operation due to operation stop, operation speed reduction, or the like can be avoided, and smooth operation such as 1/f fluctuation can be realized, for example.

Fig. 11 is a schematic front view of the combination of the operations of the airbags 202L and 202R (the airbags 202L and 202R correspond to the pressing members) into the shaking operation, in which (a) is a state before the shaking operation, (b) is a view showing the operation of moving the seat portion 20 to the left in a state in which the airbag 202R on the right side is inflated, (c) is a view showing the operation of moving the seat portion 20 to the left in a state in which the airbag 202L on the left side is inflated, and (d) is a view showing a state in which the airbags 202L and 202R on the left and right sides are driven.

In the case of fig. 11, the control device 10 can control the driving of the motor M and the air bags 202L and 202R so that the expansion and contraction of the pair of left and right air bags 202L and 202R are linked with the reciprocating movement of the moving member 21. In this way, the direction of inflation of the air bags 202L, 202R can be controlled to be the same as the direction of movement of the seat portion 20, or the direction of inflation of the air bags 202L, 202R and the direction of movement of the seat portion 20 can be controlled to be opposite to each other, so that the swinging operation can be diversified.

[ operation mode 1]

As shown in fig. 11 (b), the operation mode 1 is control for moving (interlocking) the seat portion 202 leftward in a state where the airbag 202R is inflated. In operation mode 1, first, the airbag 202R is inflated. Thus, the buttocks on the right side of the user can be further brought into close contact with the seat portion 20. In this state, the seat 202 is moved leftward. At this time, the buttocks on the right side of the user are in a state of being in close contact with the seat portion 20, and therefore the buttocks of the user can be swung leftward in a form of following the movement of the seat portion 20 leftward.

In addition, the case where the airbag 202R is inflated has been described with respect to the operation mode 1, but the airbag 202L may be inflated. At this time, since the airbag 202L is inflated first, the buttocks on the left side of the user can be further brought into close contact with the seat portion 20. In this state, the seat portion 20 is moved rightward. At this time, the buttocks on the left side of the user are in close contact with the seat portion 20, and therefore, the pressing by the inflation of the airbag 202L is combined with the movement of the seat portion 20 rightward, so that the buttocks of the user can be swung rightward.

[ action pattern 2]

As shown in fig. 11 (c), the operation mode 2 is control for moving (interlocking) the seat portion 202 leftward in a state where the airbag 202L is inflated. In operation mode 2, the airbag 202L is first inflated. Thus, the buttocks on the left side of the user can be further brought into close contact with the seat portion 20. In this state, the seat 202 is moved leftward. At this time, the buttocks on the left side of the user are in a state of being in close contact with the seat portion 20, and therefore the buttocks of the user can be swung leftward in a form of following the movement of the seat portion 20 leftward.

In addition, the case where the airbag 202L is inflated has been described with respect to the operation mode 2, but the airbag 202R may be inflated. At this time, since the airbag 202R is inflated first, the buttocks on the right side of the user can be further brought into close contact with the seat portion 20. In this state, the seat portion 20 is moved rightward. At this time, the seat portion 20 is moved rightward in a state where the buttocks on the right side of the user are in close contact with the seat portion 20, so that the user can be given a sensation of the pelvis being twisted by the inflation of the air bag 202R.

The operation mode is merely an example, and is not limited thereto. For example, as shown in fig. 11 (d), the seat portion 202 may be moved in a state where the airbags 202R and 202L are inflated, respectively. At this time, since the airbags 202R and 202L are first inflated, the buttocks of the user can be brought into close contact with the seat portion 20. Then, the seat 202 is moved leftward/rightward from this state. The buttocks of the user are closely attached to the seat portion 20 in a stable state, and thus the movement of the seat portion 20 to the left/right can be completely transmitted to the buttocks of the user, so that the buttocks of the user can be swung.

The time for the inflation and deflation of the airbags 202R and 202L may be different. For example, when the seat 20 is moved leftward, the airbag 202L is inflated on the way of moving the seat 20 leftward. In this way, a sense of being twisted can be obtained by the force of the user's buttocks moving leftward and the force of pushing rightward due to the inflation of the balloon 202L.

For example, when the seat portion 20 is moved leftward, the airbag 202R is inflated while the seat portion 20 is moved leftward. In this way, the force that pushes the air bag 202R leftwards due to the inflation is added to the force that moves the buttocks of the user leftwards, so that the force that swings the buttocks of the user leftwards can be further enhanced.

Fig. 8 is a schematic exploded view of the seat massage unit 2A of the massage apparatus 100 according to another embodiment, in which (a) is an overall view, (b) is a view in which the seat portion 20 is removed, and (c) is a view in which the seat portion 20 and the moving member 21 are removed. Fig. 9 is a schematic plan view showing a configuration of a main body 22 of a seat massage unit 2A according to another embodiment, in which (a) is a view in which the seat portion 20 is removed, and (b) is a view in which the seat portion 20 and the moving member 21 are removed. Fig. 10 is a schematic bottom view showing a configuration of a main body 22 of a seat massage unit 2A according to another embodiment, in which (a) is a view in which a seat portion 20 is removed, and (b) is a view in which the seat portion 20 and a moving member 21 are removed.

A seat massage unit 2A according to another embodiment will be described with reference to fig. 8 to 10. The seat massage unit 2A includes a seat portion 20, a moving member 21, and a main body portion 22. The seat portion 20, the moving member 21, and the body portion 22 are overlapped in order from the body of the massage device 100 toward the user sitting on the seat portion 2. That is, the moving member 21 is overlapped to be positioned below the seat portion 20, and the main body portion 22 is positioned below the moving member 21. The point of difference from the seat massage unit 2A of fig. 2 is the structure of the moving member 21. The structure of the seat portion 20 and the body portion 22, and the mechanism such as the switching member 223 for swinging the seat portion 20 provided in the body portion 22 are the same as those of the seat massaging unit 2A of fig. 2, and therefore, the description thereof is omitted.

The moving member 21 is formed of a metal plate-like member having a substantially U-shape with an opening portion located at a lower side when viewed from the front. A long hole 215 is provided in one side surface of the moving member 21 so as to be in the left-right direction in the longitudinal direction. Preferably, one (two) long holes 215 are provided on each of the left and right sides. The long hole 215 is an example of a guide portion included in the guide 23, and constitutes the guide 23 together with a pin 228, which will be described later, as an example of a guided portion. A slit Q is provided on the other side surface of the moving member 21 in the left-right direction with respect to the longitudinal direction. Preferably, a slit Q is provided between the left and right long holes 215 located at one side. By providing the slit Q on the other side surface, the operation of the switching member 223 can be prevented from being hindered.

In addition, the moving members 21 are provided in pairs in the front-rear direction. More specifically, the long hole 215 provided on one side surface of the moving member 21 is located outside.

The seat portion 20 is fixed to the upper surface 211A side of the moving member 21. In other words, the surface of the movable member 21 on the seat portion 20 side is the upper surface 211A. The upper surface 211A is the side facing the user. By disposing the two moving members 21 separately on the front and rear sides, the hand or tool can be inserted into the seat massage unit 2A only by removing the seat portion 20, and maintenance of the structure between the moving members 21 and the main body portion 22 is facilitated.

A contact member that contacts the upper surface of the main body 22 is attached to the inside of the substantially U-shaped moving member 21. More specifically, the contact member has a shaft extending in the front-rear direction inserted into the center of the contact member, and is attached to the inner side of the moving member 21 via the shaft. The contact member is attached to be located further to the outside in the left-right direction than the long hole 215 provided in the moving member 21 as an example of the guide portion.

The contact member is a member that makes rolling contact or sliding contact with the upper surface of the main body 22, and the roller 216 is an example. The roller 216 is disposed in a traveling direction that rotates in the left-right direction. As an example, one roller 216 is disposed on each of the left and right sides of the moving member 21 outside the long hole 215. Since one moving member 21 is disposed in each of the front and rear sides, four rollers 216 are disposed in total.

The shape of the body 22 and the shape of the long hole 215 of the moving member 21 are merely examples, and are not limited thereto. For example, the body 22 may be curved in a convex shape, and the moving member 21 may be curved in a convex shape in the same manner as the body 22. In this way, the seat massage unit 2A can move while drawing the locus of the convex upward. In this case, the long hole 215 of the movable member is preferably curved in a convex shape in the same manner.

The body 22 may be curved in a concave shape, and the moving member 21 may be curved in a concave shape in the same manner as the body 22. In this way, the seat massage unit 2A can move while drawing a concave downward trajectory. In this case, the long hole 215 of the movable member is preferably curved in a concave shape.

Fig. 7 is a functional block diagram of the massage apparatus 100. Referring to fig. 7, the massage device 100 includes a control device 10. The control device 10 is constituted by a computer having a processor 11 and a memory 12. The processor 11 is connected to and controls the respective sections. The processor 11 may have a part of its functions realized by a processor (not shown) mounted on the tablet pc 200 described later.

The memory 12 stores a program 121. The program 121 is a program for causing the processor 11 to execute control of the massage operation of the massage apparatus 100. The processor 11 executes the program 121 according to an operation signal from the tablet pc 200 described later. Thus, the processor 11 functions as a massage controller.

The processor 11 performs the function of the massage controller by executing the program 121, and executes the motion control process 111. The motion control process 111 includes a step of controlling the motion of each massage unit so that each massage unit performs a selected or predetermined massage motion.

The massage device 100 includes a seat massage unit 2A as a massage unit. The seat massage unit 2A has a motor M constituted by one or more motors. The motor M is an example of an actuator for causing the seat massage unit 2A to perform a massage operation (shake operation), and is included in a driving mechanism for driving the massage unit. The seat massage unit 2A includes a drive circuit 41 that drives the motor M. The driving circuit 41 controls driving of the motor M according to a control signal from the processor 11.

As an example, the processor 11 determines the driving amount of the driving circuit 41 based on body information such as the body shape and the degree of stiffness of the user, an operation signal from the tablet pc 200, and the like, and controls the driving of the motor M by the determined driving amount.

The operation signal includes, for example, a degree of a rocking motion for the buttocks or a type of the rocking motion designated by the user. Preferably, the type of shaking motion includes a shaking motion at a so-called speed of 1/f, which is a fluctuation in which the spectral density is inversely proportional to the frequency. The driving amount is, for example, the rotation speed or the driving time of the motor M. Thus, the buttocks of the user can be massaged in accordance with the user operation such as the physical information of the user, the degree of the shaking motion designated by the user, or the type of the shaking motion. For example, the processor 11 controls the drive motor M so that the operation of the seat portion 20 becomes 1/f fluctuation in which the spectral density is inversely proportional to the frequency.

The seat massage unit 2A includes drive circuits 42, 43. The driving circuits 42 and 43 drive solenoid valves for supplying and discharging air from the pump unit 9 described later to and from the airbags 202R and 202L, respectively. The driving circuits 42 and 43 and the solenoid valve are examples of actuators for massaging the seat massage unit 2A, and are included in a driving mechanism for driving the massage unit.

The drive circuits 42 and 43 control opening and closing of the solenoid valves in response to control signals from the processor 11. Thereby, the supply and exhaust of air to the air bags 202R, 202L are controlled. As a result, the seat massage unit 2A can press the buttocks from the left and right sides by the airbags 202R, 202L during the rocking operation, or can alternately press the buttocks from the left and right sides in accordance with the rocking operation. Thus, the user can be massaged by the shaking motion more effectively.

The massage device 100 includes a pump unit 9. The pump unit 9 includes a pump 93 and a driving circuit 91 that controls driving of the pump 93, and supplies and exhausts air to and from the air bags included in the respective massage units. The pump 93 is an example of an actuator that operates the pump unit 9. The driving circuit 91 controls driving of the pump 93 according to a control signal from the processor 11 to control air supply and air discharge for the airbag.

The massage device 100 includes a mechanical massage unit 8 as a massage unit. As the massaging member, the mechanical massaging unit 8 has: arms (not shown) provided with treatment members at upper and lower ends and paired left and right; and a driving circuit (not shown) for performing kneading operation for moving the left and right treatment members toward and away from each other and beating operation for alternately moving the left and right treatment members toward the user side. The driving circuit controls the driving of the massage members in accordance with a control signal from the processor 11.

The mechanical massage unit 8 may be configured to have a sensor, not shown, and to obtain body shape information of the user by detecting that the arm is at a predetermined swing position such as a shoulder. The detected signal indicating the predetermined position such as the shoulder is input to the processor 11. The processor 11 calculates the positions of other parts (neck, back, waist, etc.) with reference to the predetermined position, and detects the body shape of the user.

The massage device 100 includes arm massage units 6A, 6B, shoulder massage units 7A, 7B, and leg massage units 4A, 4B as massage units. As an example of the pressing member, each of the massage units 6A, 6B, 7A, 7B and 4A, 4B includes an unillustrated air bag and a driving circuit thereof. The driving circuit drives a solenoid valve for supplying and discharging air from the pump unit 9 to and from the airbag. The drive circuit and the solenoid valve are examples of actuators for driving the massage units 6A, 6B, 7A, 7B and 4A, 4B to perform massage operations, and are included in a drive mechanism for driving the massage units. The drive circuit controls the opening and closing of the solenoid valve in accordance with a control signal from the processor 11. Thereby, the supply and discharge of air to and from the airbag are controlled.

The massage device 100 has a sensor unit 14 as a massage unit. The sensor unit 14 includes a sensor, not shown, for detecting the degree of massage operation or the state of the user. Specifically, the sensor detects the amount of actuation of the actuator, or detects the internal pressure of the airbag. The sensor may be disposed in each massage unit. A signal indicating the sensing result of the sensor unit 14 is input to the processor 11.

The massage device 100 has the backward tilting unit 18 as a massage unit. The backward tilting unit 18 is a unit for changing the angle of the backrest 3 and the angle of the foot rest 4 according to the massage action, and includes an actuator, not shown, for changing the angle and a driving circuit thereof. The drive circuit controls the driving of the actuator in accordance with a control signal from the processor 11.

The massage device 100 includes a tablet pc 200 as an example of an operation unit for receiving a user operation. The tablet pc 200 may be a device integral with the massage device 100 or may be another device independent of the massage device 100. The tablet pc 200 receives an operation input from a user, and inputs an operation signal indicating the operation to the processor 11. Tablet computer 200 may also output information based on control signals from processor 11. The information output by the tablet pc 200 may be displayed as an image on a display (not shown), may be output as sound from a speaker (not shown), or may be both.
