Description

shaking device

technical field

The invention relates to a rocking device which achieves the effect of relaxing the body by shaking the body.

Background technique

Conventionally, there is known a chair-type massage machine capable of performing a massage operation on a user in a seated state. This chair-type massage machine is provided with a footrest member for supporting the user's two ankles, and the footrest member can swing in the left and right directions relative to the leg rest part on which the user's legs can be placed (for example, Refer to Patent Document 1).

The chair-type massage machine described in this patent document 1 is provided with a mounting plate to which a leg member is mounted, and this mounting plate is slidable in the left-right direction. This mounting plate is coupled to the rotating shaft of the electric motor as a drive source in a driveable manner. Therefore, when the rotating shaft of the motor is rotationally driven, the mounting plate slides in the left-right direction with the leg member mounted thereto based on the driving force transmitted from the motor. As a result, the user's lower body (entire legs) including both legs swings around the user's waist as the footrest member supporting the user's ankle portion reciprocates in the left-right direction. As a result, tension in the user's legs is relieved.

In addition, a pair of left and right eccentric rollers is provided on the backrest of the chair-type massage machine described in Patent Document 1. As shown in FIG. Then, when the left eccentric roller among the pair of eccentric rollers rotates so as to protrude toward the surface side of the backrest, the footrest member moves leftward. On the other hand, when the eccentric roller on the right side rotates so as to protrude toward the surface side of the backrest, the leg support member moves rightward.

As a result, when the user's lower body swings to the left, the user's upper body turns to the right, and when the user's lower body swings to the right, the user's upper body turns to the left. That is, by synchronizing the rotating motion of the eccentric roller and the rocking motion of the foot support member, the twisting motion exerts a great effect on the user's body. Therefore, it will bring a clear sense of movement to the user, and perform movements that relax the body.

Detailed ways

Hereinafter, referring to FIGS. 1 to 5 , the rocking device of the first embodiment embodied as, for example, a chair-type massage machine 10 will be described.

As shown in FIG. 1, the massage machine 10 is equipped with the leg part 11 mounted on the ground which is not shown in figure, and the seat part 12 which a user can sit on is fixed above this leg part 11. As shown in FIG. On the rear side of the seat portion 12, a backrest portion 13 for a user to rest is provided, and the backrest portion 13 can be tilted by a tilting mechanism 14 (refer to FIG. 4 ) as an angle adjustment mechanism. In addition, on the front side of the seat portion 12 is provided a leg placement portion 15 where the user can place the calf, and the leg placement portion 15 can also be tilted by the tilting mechanism 14 . In addition, armrests 16 extending from the backrest 13 to the front of the seat 12 are provided on both left and right sides of the seat 12 , and these armrests 16 allow the user to rest their arms. Then, as shown in FIG. 4 , the tilting mechanism 14 is driven and controlled according to a control command from the control unit 17 , whereby the tilt angles of the backrest 13 and the legrest 15 are adjusted.

In addition, on the leg rest portion 15 , one concave leg support portion 18 capable of being inserted into the lower leg of the user is arranged on the left and right sides. Each leg support part 18 has the opposing surface 18a which opposes the calf of a user's calf part. Then, as shown in FIG. 4 , the swing drive unit 19 is driven and controlled according to the control command from the control unit 17 , whereby each leg support unit 18 swings in the left-right direction. Moreover, in 1st Embodiment, the body support part which supports the body of the user who uses the massage machine 10 is comprised by the seat part 12, the leg support part 18 (leg rest part 15), and the back part 13.

In addition, as shown in FIG. 2( a ), a back airbag 20 a , a seat airbag 20 b , and a leg airbag 20 c are respectively provided on the backrest 13 , the seat 12 , and the pair of left and right leg support portions 18 . As shown in FIG. 4 , each airbag 20 a , 20 b , 20 c acts as an expansion and contraction member, and the control unit 17 issues a control command to drive and control the air pump so that these airbags perform expansion and contraction between the expanded state and the contracted state. Then, by expanding and contracting these airbags 20a, 20b, and 20c, the body of the user seated on the seat portion 12 is pressed from the back side. Each of the back airbag 20a, the seat airbag 20b, and the leg airbag 20c is an example of a pressing mechanism that presses the user's body from the back side. In addition, since these airbags 20a, 20b, and 20c have the same structure, in the following description, the structure of the seat part airbag 20b provided in the seat part 12 is demonstrated.

As shown in FIG. 2( b ), on the upper surface of the seat portion 12 , an opening-shaped recess 24 extending substantially over the entire range in the left-right direction of the seat portion 12 is formed. A seat airbag 20 b having a planar shape substantially the same as the opening shape of the recess 24 is accommodated in the recess 24 . in addition. The upper surface of the seat airbag 20 b accommodated in the recess 24 is flush with the upper surface of the seat 12 .

Then, as shown in FIG. 3( a), in the seated state in which the user's thighs A are placed on the upper side of the seat airbag 20b and the buttocks C are supported on the seat 12, the seat airbag 20b responds to the When the control command of the control part 17 inflates, the upper surface of the seat part airbag 20b protrudes from the upper surface of the seat part 12 (refer FIG.3(b)). As a result, by raising the user's thighs A placed on the upper surface of the seat airbag 20b upward, the seat 12 supports the buttocks C to change the sitting posture of the seated user.

Next, the operation of the massage machine 10 configured as described above, especially the operation when the user's sitting posture is changed when the user's lower leg B (see FIG. 5 ) is rocked, will be described in detail.

In the massage machine 10 according to the first embodiment, when the body of the user seated on the seat 12 is stimulated by the rocking operation, first, the control unit 17 controls the driving of the rocking drive unit 19 . Then, by oscillating each leg support 18 to the left and right, the user's lower leg B supported by these leg supports 18 is oscillated to the left and right in conjunction with each leg support 18 . Here, the control unit 17 inflates at least one of the back airbag 20a, the seat airbag 20b, and the leg airbag 20c in order to change the transmission form of the shaking stimulus to the user's body. Hereinafter, an operation example of the airbags 20a, 20b, and 20c will be described.

As shown in FIG. 5(a), when the control unit 17 inflates the leg airbag 20c, the leg airbag 20c is directed toward the opposing surface 18a of the leg support portion 18 (refer to FIG. 2(a)). The vertical direction (in Fig. 5(a) is obliquely upward) protrudes, and the facing surface 18a faces the calf of the calf part B. As shown in FIG. Then, with the inflation operation of the leg airbag 20c, the lower leg B of the user placed on the leg airbag 20c is lifted upward while being separated from the leg support portion 18 . As a result, the user's sitting posture changes, and the lower legs B of the user seated on the seat portion 12 extend forward. In this way, when the user's sitting posture changes due to the expansion of the leg airbags 20c during the rocking motion of the lower legs B, the user's lower legs B will use the leg airbags 20c as the rocking fulcrum to a greater extent. As a result, the form of transmission of shaking stimuli from the lower leg B to the upper half of the body changes. Therefore, the user's body can be shaken and stimulated with a sense of movement different from that before the leg airbag 20c inflates, achieving the effect of relaxing the body.

In addition, as shown in FIG. 5( b ), when the control unit 17 inflates the seat airbag 20b, the seat airbag 20b is directed toward the direction perpendicular to the surface of the seat 12 that supports the thigh A of the user. Protrude straight above. Then, with the inflation operation of the seat airbag 20b, the user's thigh A placed on the seat airbag 20b is lifted upward while being separated from the seat 12 . In addition, as shown in FIG. 5( b ), at this time, the user's buttocks C are still supported by the seat portion 12 . As a result, the user's sitting posture changes, and the thighs A of the user seated on the seat portion 12 are displaced upward. As a result, the user's entire lower body swings more largely around the seat airbag 20b as a swing fulcrum, and the form of transmission of the shaking stimulus from the user's lower legs B to the upper body changes. Therefore, it is possible to give the user's body a shaking stimulus with a different sense of motion than when the leg airbags 20c are inflated, thereby achieving the effect of relaxing the body.

In addition, as shown in FIG. 5( c), when the control unit 17 inflates the back airbag 20a, the back airbag 20a faces in a direction perpendicular to the front of the backrest 13 supporting the user's back (in FIG. 5 (c) obliquely above the middle front) prominent. Then, the back of the user placed on the back airbag 20 a is separated from the backrest 13 along with the inflation operation of the back airbag 20 a. As a result, the user's sitting posture changes, and the user's back is lifted upward from the backrest 13 . In particular, in the first embodiment, when the back airbag 20a is inflated, the controller 17 drives and controls the tilting mechanism 14 so that the backrest 13 is tilted backward and the leg rest 15 (each leg support Part 18) tilts until it is in a substantially horizontal state. Therefore, the part from the user's lower body to the waist and abdomen will be more widely rocked with the dorsal airbag 20a as the rocking fulcrum, thereby changing the form of transmission of the rocking stimulus from the user's lower legs B to the upper body. Therefore, it is possible to give the user's body a shaking stimulus with a different sense of motion than when the leg airbags 20c and the seat airbags 20b are each inflated, thereby achieving the effect of relaxing the body.

According to the rocking device of the first embodiment, the effects described below can be obtained.

(1) Each of the airbags 20a, 20b, 20c presses different parts of the user's body in the body axis direction from the back side (the part corresponding to the backrest 13, the part corresponding to the seat part 12, or the part corresponding to the leg support part). 18) to change the user's sitting posture. Therefore, when a part of the body support portion (the leg support portion 18 in the first embodiment) performs a swinging motion, it is possible to give various motion sensations to the user's body.

(2) Each of the airbags 20a, 20b, and 20c expands and contracts so that the pressing force acts on the user's body gradually from the back side. Thereby, the user's sitting posture can be changed gradually.

(second embodiment)

Next, massage machine 10 (swing device) according to the second embodiment will be described with reference to FIG. 6 and FIG. 7 . The second embodiment is different from the first embodiment in that the airbags are provided on a plurality of parts of the body at different positions in the user's body axis direction and body width direction (ie, left and right directions). Therefore, in the following description, configurations different from those of the first embodiment will be mainly described, and configurations that are the same as or equivalent to those of the first embodiment will be assigned the same reference numerals and redundant descriptions will be omitted.

As shown in FIG. 6 , in the massage machine 10 according to the second embodiment, a plurality of (three in the second embodiment) are arranged at intervals in the left-right direction on the upper side of the backrest 13 . Back airbag 20a. For example, the central back airbag 20a among the three back airbags 20a is arranged at a substantially central position in the left-right direction of the backrest portion 13 so as to correspond to the user's back muscles. Two of the three back airbags 20a located on the left and right sides are arranged at opposite ends of the backrest 13 in the left-right direction so as to correspond to the user's left and right shoulders.

In addition, on the seat 12, a plurality of (two in the second embodiment) seat airbags 20b are provided at intervals in the left-right direction, and these seat airbags 20b are long at the front and rear ends of the seat 12. extend. For example, two seat airbags 20b are provided on both left and right sides of the seat 12 so as to be bilaterally symmetrical with respect to the central position of the seat 12 in the left-right direction.

Thus, in the second embodiment, the airbags 20a, 20b, and 20c are provided so as to be able to press a plurality of parts of the body at different positions in the user's body axis direction and left-right direction from the user's back side. In addition, in the second embodiment, three back airbags 20a are provided in the left-right direction on the backrest part 13, two seat airbags 20b are provided in the left-right direction on the seat part 12, and each leg support part 18 is provided. There is 1 leg airbag 20c. Therefore, the number of parts that press the user's body in the left-right direction depends on the parts of the body in the body axis direction (that is, the parts corresponding to the backrest 13, the parts corresponding to the seat part 12, and the parts corresponding to the respective legs). The position corresponding to the part supporting part 18) is different. Furthermore, since each seat airbag 20b provided on the seat 12 is formed long in the front-rear direction, not only the user's thigh A but also the buttocks C can be pushed upward.

Next, the operation of the massage machine 10 configured as above, especially the operation of the seat airbag 20b changing the user's sitting posture when the user's calf B is rocked, will be described in detail.

As shown in Fig. 7(a), in the massage machine 10 of the second embodiment, when the pair of left and right seat airbags 20b provided on the seat 12 are in a state flush with the upper surface of the seat 12, the user The left and right thighs A are supported on the seat 12 in a substantially horizontal posture.

Here, when the user's lower leg B is rocked by the leg support part 18, according to the control command from the control part 17, the seat airbag 20b on the right side is directed from the upper surface of the seat part 12 toward the The form protruding vertically above is expanded. Then, as shown in FIG. 7( b ), the right thigh A and the right part of the buttocks C are lifted upward by the right seat airbag 20 b. As a result, the user's sitting posture changes, and the user's lower body is twisted clockwise when viewed from the front. As a result, the user's body can be given a shaking stimulus with a different sense of motion than before the right seat airbag 20b inflates, thereby achieving the effect of relaxing the body.

Also, when the lower leg B is rocking, the seat airbags 20b on the left and right sides are inflated so as to protrude vertically upward from the upper surface of the seat 12 according to the control command from the control unit 17 . Then, as shown in FIG. 7(c), the left and right thighs A and the entire buttocks C are lifted upward by the left and right seat airbags 20b. As a result, the user's sitting posture is changed by lifting up the left and right thighs A while maintaining the substantially horizontal posture. As a result, it is possible to give the user's body a shaking stimulus with a different sense of movement from when the seat airbag 20b is not inflating and when one of the two seat airbags 20b is inflating. The effect of relaxing the body.

According to the swing device of the second embodiment, in addition to the effects (1) and (2) of the first embodiment described above, the following effects can be obtained.

(3) On the backrest 13 , the back airbags 20 a press a plurality of parts of the body (for example, the back muscles and both left and right shoulders) at different positions in the left-right direction. Also, in the seat 12, the seat airbags 20b press a plurality of parts of the body (for example, the left and right thighs A and the left and right parts of the buttocks C) at different positions in the left-right direction. Therefore, each of the airbags 20a, 20b, and 20c presses different parts of the body in the body axis direction and in the left-right direction. Thereby, the user's sitting posture can be changed in more ways. As a result, when a part of the body support portion (the leg support portion 18 according to the second embodiment) performs a rocking motion, various motion sensations can be given to the user's body.

(4) The airbags 20a, 20b, 20c are provided so that the number of parts that press the user's body in the left-right direction depends on the parts of the body in the body axis direction (that is, the parts corresponding to the backrest 13, the parts corresponding to the seat The part corresponding to the leg support part 12 and the part corresponding to each leg support part 18) are different. Therefore, the user's body is pressed by the number of air cells corresponding to the respective parts of the body in the body axis direction. Thereby, a good sense of movement can be brought to the user's body to achieve the effect of relaxing the body.

(5) A plurality of (three in the second embodiment) back airbags 20 a are provided on the backrest portion 13 . Therefore, the back airbag 20a is supported by the backrest portion 13, and presses a plurality of locations close to each other. In addition, a plurality of (two in the second embodiment) seat airbags 20 b are provided on the seat 12 . Therefore, the seat airbag 20b is supported by the seat 12, and presses a plurality of locations close to each other. In this configuration, it is possible to continuously change the pressing part that presses the user's body.

(third embodiment)

Next, a massage machine 10 (swing device) according to a third embodiment will be described with reference to FIGS. 8 and 9 . The third embodiment differs from the above-described embodiments in that the maximum inflation amount of the leg airbags 20c is changed when the user's legs are rocked. Therefore, in the following description, configurations different from those of the first embodiment will be mainly described, and configurations that are the same as or equivalent to those of the first embodiment will be assigned the same reference numerals and redundant descriptions will be omitted.

As shown in FIG. 8( a ) and FIG. 8( b ), in the massage machine 10 of the third embodiment, a rectangular plate-shaped rotating member 31 is provided on each leg support portion 18 , and the rotating member 31 has a Almost the entire range in the left-right direction supports the width dimension of the calf of the user. The upper end portion of the rotating member 31 is rotatably supported by a rotating shaft 32 inserted through both side wall portions of each leg support portion 18 . Therefore, the rotating member 31 is arranged between the opposing surface 18a of each leg rest 18 and the user's calf. Each leg airbag 20c is provided on the facing surface 18a of the corresponding leg support portion 18 and interposed between the facing surface 18a and the rotating member 31 .

As shown in FIG. 9( a ), when the leg airbags 20 c of the leg support 18 are contracted, the user's lower leg B is not pushed forward by the rotating member 31 . Therefore, the soles of the user's feet are in close contact with or in contact with the leg rest 18 .

Here, when the user's calf B is rocked by the leg support 18 , the leg airbag 20 c is inflated in accordance with a control command from the control unit 17 . Then, as shown in FIG. 9( b ), along with the expansion operation of the leg airbag 20c, the rotating member 31 rotates forward about the rotating shaft 32, so that the lower leg B moves forward in the form of separating from the leg support portion 18. lift up. Then, the user's sitting posture changes, and the entire sole of the user's feet is displaced obliquely upward and forward so as to be away from the leg rest 18 . As a result, it is possible to give the user's body a shaking stimulus with a different sense of motion than before the leg airbags 20c perform the inflation motion, thereby achieving the effect of relaxing the body.

Then, when the inflation amount of the leg airbag 20c reaches the target inflation amount, the control unit 17 stops the driving of the air pump to maintain the inflated shape of the leg airbag 20c at a predetermined size. The target inflation amount is set in advance as the maximum amount of pressing against the user's body. At this time, the user's sitting posture is maintained in such a state that the entire lower leg B is displaced obliquely forward and upward under the maximum pressing force of the leg airbag 20c having an inflated shape corresponding to the target inflation amount. . Therefore, it is possible to bring shaking stimulation to the user's body with a sense of movement different from that before the leg airbag 20c inflates, achieving the effect of allowing the body to continue to relax for a certain period of time.

In addition, when the user's calf B is rocking, according to the control command from the control unit 17, when the target inflation amount of the leg airbag 20c is increased, the inflated shape of the leg airbag 20c will become more stable. big. Then, as shown in FIG. 9( c ), as the leg airbag 20c further inflates, the rotating member 31 rotates forward more substantially around the rotating shaft 32 , so that the calf B is lifted from the leg support portion 18 . The outgoing form lifts forward more dramatically.

Then, the user's leg is displaced obliquely upward and forward so that the entire sole of the user's foot is separated from the leg support portion 18 to a greater extent. Therefore, the sitting posture of the user changes compared to before the maximum pressing amount corresponding to the target inflation amount of the leg airbag 20c is changed. As a result, it is possible to give the user's body a shaking stimulus with a different sense of motion than before changing the target inflation amount (maximum pressing amount) of the leg airbag 20c, thereby achieving the effect of relaxing the body.

According to the rocking device of the third embodiment, in addition to the effects (1) and (2) of the first embodiment described above, the following effects can be obtained.

(6) By changing the target inflation amount that prescribes the maximum amount of compression caused by the inflation operation of the leg airbag 20c, the pressing force on the lower leg B can be changed in various forms and the user's pressure can be changed in various forms. pose. Therefore, it is possible to change the motion feeling of the motion to relax the body which acts on the user's body when the calf portion B performs the rocking motion.

(7) Sufficient stimulation can be given to the user's body by maintaining the inflated state (inflated shape) of the leg airbags 20c and maintaining the user's sitting posture.

(fourth embodiment)

Next, a massage machine 10 (swing device) according to a fourth embodiment will be described with reference to FIG. 10 . The fourth embodiment is different from each of the above-mentioned embodiments in that at least two of the plurality of airbags (pressing means) are provided so as to partially overlap in a direction intersecting the direction of expansion and contraction of the airbags. In addition, in the fourth embodiment, the seat airbags 20b are partially overlapped. Therefore, in the following description, configurations different from those of the first embodiment will be mainly described, and configurations that are the same as or equivalent to those of the first embodiment will be assigned the same reference numerals and redundant descriptions will be omitted.
