DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
FIG. 1 is a schematic configuration diagram of the relaxation device of the present embodiment. As shown in FIG. 1, the relaxation device 10 has a bottom 11 a of a base 11 placed on a floor surface (not shown) and a swing drive device 12 as a swing drive means provided on the base 11. And a body support member 13 as body support means that is swung by the swing drive device 12.

The swing drive device 12 includes a motor 20, a speed reducer 21, a crank mechanism 22, and a link member 23.
The motor 20 is provided on the upper surface of the bottom 11a of the base 11, and its driving is controlled by a controller 24 provided on the upper surface of the bottom 11a and a controller 24 as a refresh control means. The speed reducer 21 is provided on the upper surface of the bottom 11a of the base 11 and is connected to the motor 20 so as to decelerate and output the driving force of the motor 20.

  The crank mechanism 22 includes two connecting members 22a and 22b, and converts the rotational drive of the speed reducer 21 into an arc motion having a very large radius. The connection member 22a has a base end connected to the output shaft of the speed reducer 21 so as to be integrally rotatable, and a tip end connected to the base end of the connection member 22b to be rotatable. The distal end of the connection member 22b is connected to the lower portion of the square frame-shaped base portion 25 to which the body support member 13 is fixed.

  The base 11 is provided with a support frame 11b projecting upward from the bottom 11a, and the two link members 23 have their base ends at a predetermined interval above each support frame 11b. While being rotatably connected, each tip is rotatably connected to the lower portion of the base portion 25. That is, the two link members 23 rotate about the base end, and the body support member 13 fixed to the base portion 25 is locked to the rocking chair based on the driving force from the crank mechanism 22. And so on. In the present embodiment, the path when the body support member 13 moves from the rear to the front is defined as the forward path, and the path when the body support member 13 is moved from the front to the rear is defined as the return path.

  A seat surface 30 constituting a chair-type body support member 13 is fixed to the upper portion of the base portion 25 so as to be movable together with the base portion 25, and a backrest portion 31 fixed to the rear portion of the seat surface 30 so as to be tiltable. And an ottoman 32 fixed to the front portion of the seating surface 30 and armrests 33 fixed to the left and right sides of the seating surface 30.

  As shown in FIG. 2, the reclining mechanism 34 that tilts the backrest 31 is controlled by the controller 24 to tilt the backrest 31 appropriately.

  The backrest 31 is provided with a pair of left and right airbags 40, 41 on both sides of the upper stage corresponding to the left and right shoulders of the user, and airbags 42, 43, 44 as back airbags in the middle. Are installed corresponding to the user's back (upper back, middle back and lower back), and airbags 45 and 46 are provided on both sides of the lower part corresponding to the left and right waists of the user. On the left and right sides of the seat 30, two airbags 47 and 48 are provided corresponding to the user's buttocks and thighs. The airbags 40 to 48 provided corresponding to each part of the user are routed toward an air pump 49 provided at the lower portion of the seating surface 30 via a connection hose (not shown). The driving of the air pump 49 is controlled by the controller 24 so that the airbags 40 to 48 can be inflated and contracted.

Next, the operation of the relaxation apparatus 10 configured as described above will be described with reference to FIGS.
The controller 24 is a mode for driving the rocking drive device 12 to perform the relaxing rocking of the body support member 13, or a mode for interlocking the relaxing rocking with each of the airbags 40 to 48 and the backrest portion 31, etc. Various operation modes are set. Among them, there is a relaxing swing mode having a refresh function. In this operation mode, first, [relaxation rocking] is performed to give a relaxing effect to the user, and after a predetermined time has elapsed, the operation mode is terminated by switching from [relaxation rocking] to [refresh rocking]. It has become. FIG. 3 shows changes in amplitude and frequency when the body support member 13 is swung by the swing drive device 12 in the operation mode.

[Relaxing rocking]
First, the controller 24 reclines so that the reclining angle θ between the seat surface 30 and the backrest portion 31 changes from the standing state (for example, the reclining angle θ = 120 degrees) to the reclining state (for example, the reclining angle θ = 150 degrees). The mechanism 34 is controlled to tilt the backrest 31 by a predetermined angle (for example, 30 degrees). At this time, the operating speed of the backrest 31 is controlled so as to gradually decrease.

  Then, the controller 24 starts the swing interval (frequency) of the swing operation of the body support member 13 with time from, for example, 0.35 Hz so as to guide the user from the awake state to the relaxed state, for a predetermined time. The motor 20 is controlled so as to be gradually decreased in increments of 0.05 Hz to 0.2 Hz between A and A, and the motor 20 is controlled and relaxed so as to give random fluctuation to the swing width (amplitude) of the swing operation. Swing.

  Also, as shown in FIGS. 2 and 4, the controller 24 drives the air pump 49 so that the duty ratio (output) becomes 100% at the same time as the body support member 13 is moved forward, for example, Among the plurality of airbags 40 to 48 provided on the backrest portion 31 and the seating surface 30 of the body support member 13, the waist airbags 45 and 46 that have the same direction of action on the user's body are inflated. Then, the controller 24 is driven in a state where the body support member 13 is moved backward, which is the return path, and at the same time, the duty ratio of the air pump 49 is reduced to 70%, so that the amount of expansion per unit time is reduced. The bags 45 and 46 are inflated. Then, after the above-described operation of inflating the airbags 45 and 46, the controller 24 stops the driving of the air pump 49 at the same time that the body support member 13 is moved forward, and the body support member 13 reciprocates once. The airbags 45 and 46 are contracted.

  That is, in the above-described airbag operation, air supply and exhaust are switched each time the body support member 13 is reciprocated once with respect to the airbags 45 and 46, and the body support member 13 is moved forward during the inflating operation. In addition, the duty ratio of the air pump 49 is set to be higher than the backward operation.

  Accordingly, the duty ratio of the air pump 49 can be increased in accordance with the forward movement of the body support member 13 to improve the feeling of relaxation of the user, such as increasing the floating feeling of the user's body. A relaxing effect can be imparted.

  Next, after the predetermined time A has elapsed, until the predetermined time B, the controller 24 causes the amplitude to fluctuate at the final operation, that is, the body support member 13 at a frequency of 0.2 Hz which is the lower limit value of the frequency of the present embodiment. In this way, the motor 20 is controlled so that the user continues to swing so as to change from the relaxed state to the sleep state. Further, between the predetermined times A and B, the controller 24 stops the operation of the airbags 40 to 48 by stopping the driving of the air pump 49.

[Refreshing rocking]
After the predetermined time B has elapsed, the controller 24 changes the frequency of the swing operation from 0.2 Hz to 0.3 Hz, 0.3 Hz to 0.4 Hz, so as to invite the user from the sleep state (relaxed state) to the awake state. The motor 20 is controlled so as to change stepwise from 0.4 Hz to 0.6 Hz. At this time, the timing of the frequency change is controlled by the controller 24 so that the swinging motion of the body support member 13 changes after, for example, 10 reciprocations. In addition, the controller 24 controls the motor 20 so as to increase the magnitude of the amplitude stepwise in synchronization with the timing of frequency change.

  Further, during the refresh swing, the controller 24, for example, moves the body support member 13 backward, which is the return path, and simultaneously stops the air pump 49 at a duty ratio (output) of 100% during the above-described series of operations. Lumbar airbags 45 and 46 having the same action direction applied to the user's body among the plurality of airbags 40 to 48 provided on the backrest portion 31 and the seating surface 30 of the body support member 13. Inflates. Then, the controller 24 is driven in a state where the body support member 13 is moved forward, which is the outward path, and at the same time, the duty ratio of the air pump 49 is reduced to 70%, so that the amount of expansion per unit time is reduced. The bags 45 and 46 are inflated. Then, after the above-described inflating operation of the airbags 45 and 46, the controller 24 stops the driving of the air pump 49 at the same time as the body support member 13 is moved to the rear, which is the return path, and the body support member 13 reciprocates once. The airbags 45 and 46 are contracted.

  That is, in the above-described airbag operation, air supply and exhaust are switched each time the body support member 13 is reciprocated once with respect to the airbags 45 and 46, and the body support member 13 is moved rearward during the inflating operation. In addition, the duty ratio of the air pump 49 is set to be higher than that during forward operation.

  Accordingly, the duty ratio of the air pump 49 is increased in accordance with the rearward movement of the body support member 13, and the refreshing operation feeling of increasing the user's body standing feeling can be improved. A refreshing effect can be imparted.

  After the airbag operation described above is completed, the controller 24 controls the air pump 49 to supply air to the airbags 42, 43, and 44 so as to lift the back and stretch the back. Then, the controller 24 controls the reclining mechanism 34 so that the reclining angle θ is changed from the reclining state (for example, the reclining angle θ = 150 degrees) to the standing state (for example, the reclining angle θ = 120 degrees). An angle (for example, 30 degrees) is set up.

Next, characteristic effects of the present embodiment will be described.
(1) The controller 24 increases the output of the air pump 49 while the body support member 13 is moving forward during the relaxed swing, and decreases the output of the air pump 49 while the body support member 13 is moving backward. Be controlled. That is, when the body support member 13 is moving forward, the output (duty ratio 100%) of the air pump 49 is made larger than the output (duty ratio 70%) of the air pump 49 while the body support means is moving backward. It is possible to improve the feeling of relaxing movement such as increasing the floating feeling of the body, and to provide an effective relaxing effect.

  (2) The controller 24 controls the swing driving device 12 so as to perform refresh swing that switches both from the relax swing swing and increases the frequency and amplitude of the swing motion, and the user who is in a relaxed state. Has a function of refreshing. Then, the controller 24 controls so that the output of the air pump 49 is decreased while the body support member 13 is moving forward, and the output of the air pump 49 is increased while the body support member 13 is moving backward. That is, by making the output of the air pump 49 larger than the output of the air pump 49 while the body support member 13 is moving forward while the body support member 13 is moving backward, the unit of the airbags 45 and 46 during the rearward movement. The amount of expansion per time can be increased, the refreshing feeling of the user's body standing can be improved, and an effective refreshing effect can be imparted.

In addition, you may change embodiment of this invention as follows.
In the above embodiment, the refresh swing is performed after the relax swing, but only the relax swing may be performed without performing the refresh swing.

  In the above embodiment, the duty ratio (output) of the air pump 49 with respect to the airbags 45 and 46 according to the swinging (moving) direction of the swinging motion of the body support member 13 during relaxed swing and refresh swing. However, the present invention is not limited to this. For example, the duty ratios of the other airbags 40 to 44 having the same action direction applied to the user's body may be changed. In addition, about the airbags 47 and 48 provided in the seat surface 30, when the action direction given to a user's body is the same, it is good also as a structure which changes a duty ratio similarly to the airbags 45 and 46.

  Moreover, when using several airbags, it is good also as a structure which switches the airbag inflated, for example, whenever the body support member 13 reciprocates once. As a specific example, for example, when the airbag 42 is inflated during the first reciprocation of the body support member 13 during relaxation swinging, the airbags 43 and 44 are in a contracted state, and the airbag 43 is inflated during the second reciprocation. Sometimes, the airbags 42 and 44 are in a contracted state, and when the airbag 44 is inflated in the third reciprocation, the airbags 42 and 43 are controlled to be in a contracted state. In this case, the output of the air pump 49 when each is expanded is the same as that in the above embodiment, for example.

  In addition, for example, when the body support member 13 is moved forward, the airbag 43 is inflated by driving the duty ratio of the air pump 49 at 100% to inflate the airbag 42, so that the body support member 13 is moved rearward. It is also possible to control the airbags 42 and 44 to be in a contracted state while the airbag 43 is inflated by driving the duty ratio of the air pump 49 at 70% during movement. That is, it is good also as a structure which switches the airbag which inflate-operates for every one way, and the airbag which shrink | contracts.

  In the above embodiment, during the inflation operation of the airbags 45 and 46 during the relaxed swing, when the body support member 13 is moved forward, the air pump 49 is driven at a duty ratio of 100% so that the body support member 13 The air pump 49 is driven at a duty ratio of 70% when moved rearward. However, the present invention is not limited to this and may be driven at other duty ratios. The point is that the air pump 49 may be driven at a higher output (high duty ratio) when the body support member 13 is moved forward than when the body support member 13 is moved rearward.

In the above embodiment, during the inflation operation of the airbags 45 and 46 during the refresh swing, when the body support member 13 is moved rearward, the air pump 49 is driven at a duty ratio of 100%, so that the body support member 13 When moved forward, the air pump 49 is driven at a duty ratio of 70%. However, the present invention is not limited to this and may be driven at other duty ratios. The point is that the air pump 49 may be driven at a higher output (high duty ratio) than when the body support member 13 is moved forward when the body support member 13 is moved backward.
In the above embodiment, the controller is configured so that the start of the forward movement and the backward movement of the body support member 13 and the start of the inflating and contracting operations of the airbags 45 and 46 are simultaneously performed in the relaxing swing and the refresh swing. However, the present invention is not limited to this. For example, the airbag 40 to 44 other than the airbags 45 and 46 and the airbag 47 or 48 of the seat 30 may be individually or inflated and the body support member 13 may be moved forward. It may be operated simultaneously with the backward movement.

  In the above embodiment, the relaxation swing is performed by swinging the amplitude. However, the present invention is not limited to this. For example, the frequency may be changed instead of the amplitude. Further, both the amplitude and the frequency may be fluctuated.

  In the above embodiment, the motor 20 is controlled by the controller 24 so that the frequency of the swinging motion of the body support member 13 (base portion 25) is between 0.35 Hz and 0.2 Hz during relaxed swinging. However, the motor 20 may be controlled in other frequency bands for relaxing.

  In the above embodiment, the controller 20 controls the motor 20 so that the frequency of the swinging motion of the body support member 13 (base portion 25) changes from 0.2 Hz to 0.6z stepwise during refresh swinging. However, other frequency bands to be refreshed may be used.

  In the above embodiment, the motor 20 is controlled by the controller 24 so as to synchronize and increase the amplitude and frequency of the swinging operation after the predetermined time B has elapsed, but it is not necessary to synchronize. Further, both the amplitude and the frequency may not be increased, but only one of them may be increased.

  In the above embodiment, the control of each part by the controller 24 is switched at the predetermined time A and the predetermined time B. However, the present invention is not limited to this. For example, the user can switch the control of each part by the controller 24. A switch may be provided to perform switching at a timing desired by the user.

-In above-mentioned embodiment, although the body support member 13 was comprised in the chair type | mold, you may comprise not only in this but a bed type | mold or another shape, for example.
In the above embodiment, although not particularly mentioned, a configuration for applying music or vibration corresponding to relaxation rocking or refresh rocking may be added.
