Above-mentioned grabbing pinched massaging action, can with above-mentioned up and down, about, fore-and-aft direction carries out the driving of treatment element combination.That is, treatment element 2a, 2b under the state of the shoulder of catching user are being moved up and down or to the cervical region side shifting of user.

Action when then explanation is upheld actuator A2.Actuator A2 is upheld, and then treatment element arm 12 is forwards rotated, and treatment element 2a forwards moves.In addition, as mentioned above, make treatment element arm 12 carry out elastic force-applying by the actuator A2 that works as air spring (empty mood ば ね), so grab when pinching massage, the shoulder of user grabbed bestow the power of applying when pinching, the treatment element 2a that contacts with the upper face side of shoulder is difficult to rearward escape, and can provide more reliable grabbing to pinch massage.In addition, because stretched condition that can corresponding actuator A2, the elastic force-applying that above-mentioned echopraxia is pressed with air and apply load, thus make treatment element 2a, 2b moves up and down and under the situation of friction massage, the massage pressure of treatment element 2a and 2b can be pressed according to air and be changed.For example, shown in Figure 14 (A), treatment element 2a, when 2b is mobile downwards, move the below that contacts with user and hinder treatment element 2a, the moment treatment element arm 12 that then surpasses the load value of the regulation of pressing based on air begins to shake, so and then can make force application mechanism descend the back surfaces that on two sides of treatment element 2a and 2b, to push user after this.In addition, Figure 14 (B) is with the shaking quantity and the relation of bestowing the power that applies of treatment element 2a of the treatment element arm 12 of an example expression actuator A2.

In addition, uphold, but can dwindle the swing range of 14 on treatment element arm 12 with the first arm 13 and second arm in fact by making actuator A2, so, when actuator A2 upholds most, but swing range in fact roughly approaches zero, does not carry out above-mentioned echopraxia.As a result, can provide stronger massage by treatment element 2a.In addition, though but dwindled swing range, so since when bestowing heavy load since actuator A2 to dwindle also be outstanding on safety.

In addition, but the maximum of swing range with 14 on the treatment element arm 12 of the first arm 13 and second arm by position limiting structure 120 decisions of being located on the treatment element arm 12, in addition, the slewing area of second arm, 14 phase antithetical phrase arms 12 is by position limiting structure 140 decisions.And then 12 of second arm 14 and treatment element arm are furnished with stirring disc spring (not shown), the application of force on the big direction of the interval of treatment element 2a, 2b change.

In addition, even during actuator A2, make massage intensity be set at " by force " by two drive divisions, then preferably control so promptly makes massage intensity form " weak " state (with reference to Figure 15 (A)) earlier, and actuator A2 is upheld, afterwards, shown in Figure 15 (B), make massage intensity return " by force ".Thus, in any case the air of actuator A2 is pressed height, actuator A2 is upheld.Such control is useful for the stable massaging action of the influence that the uncertain factors such as body weight, the bodily form and user mode that reduce user are provided.

Like this, the masseur 1 according to present embodiment not only can provide kneading massage and friction massage, can also provide grabbing of shoulder to pinch massage, and these are massaged and control by appropriate combination, can obtain more resultful massage.

In addition, in the masseur 1 of present embodiment, be provided with detection and bestow the pressure of treatment element arm 12 from the user on the backrest 90, detect the shoulder position test section of the shoulder position of user thus, carry out feedback control according to the shoulder position test section, thereby the higher massaging action of stability as described below can be provided.

Promptly, control part 8, make making first drive division under the situation that treatment mechanism 3 is moved upward, the position of the treatment element 2a of upper side arrives than by the high position of the detected shoulder position of shoulder position test section the time, make the treatment element 2a of upper side outstanding, control simultaneously as the actuator A2 of force application mechanism and second drive division (motor 60) any retreats the treatment element 2b of lower side at least.For example, when making treatment element arm 12 more rising upward in the below from portion position shoulder to shoulder, order as Figure 16 (A) → 16 (B) → 16 (C) → 16 (D), make treatment element 2a forwards outstanding, be positioned under the state above more of portion position shoulder to shoulder, the treatment element 2a that becomes upper side is forwards outstanding, simultaneously, and the state that the treatment element 2b of lower side submerges the shoulder rear.In addition, towards the forwards side-prominent direction application of force, as mentioned above, can drive the motor 60 or the actuator A2 of second drive division, to treatment element 2a at this drive actuator A2.In addition, treatment element arm 12 is from shoulder position below when rising upward, if the forwards outstanding state of treatment element 2a is then controlled this state of keeping more.

In addition, more during the top, the treatment element 2b of lower side is forwards outstanding for the shoulder position that treatment element 2a, 2b are positioned at human body, and then under the situation that treatment mechanism 3 descends, as shown in figure 17, the treatment element 2b of lower side is by last user shoulder.Under this state, treatment element arm 12 is roughly boundaries of swing range, escapes so treatment element 2b can not and then be moved upward again.Therefore, Tu Chu treatment element 2b is applied on the shoulder of user over-drastic pressing force.But, as shown in figure 18, the treatment element 2b of lower side retreats with the degree of the back surfaces of imitation user, simultaneously, the forwards outstanding state of the treatment element 2a of side makes treatment element 3 descend from the top of the shoulder position of user up, though then in the decline of treatment element arm 12 treatment element arm 12 lean on the shoulder of user, treatment element arm 12 is also in the scope that can shake, the actuator A2 that upholds is compressed, and treatment element 2a can escape upward.By such control, can prevent from the shoulder of user is applied over-drastic pressing force.

In addition, detect the pressure detecting portion (shoulder position test section) that is applied to the pressure on the treatment element arm 12 and preferably adopt following structure.That is, the pressure detecting portion of present embodiment is mainly calculated pressure (body pressure: the extensometer formation pressure that is subjected to the user human body) by the elasticity displacement of the elastomer 64 in the gear-box 62 that is configured in second drive division and this elastomer 64 of detection.

Figure 19 represents the structure in the gear-box 62.On the output shaft 60a of the motor 60 of second drive division swivel 71 is installed, can link movably in the axial direction on this swivel 71 has worm shaft 72.Worm shaft 72 is provided with bearing 73, and this bearing 73 can move in the axial direction freely and embed in the race bearing 74 that is fixed on the gear-box 62.Thus, worm shaft 72 can move axially, and is rotated by swivel 71 by the rotation of motor 60.On worm shaft 72, axial central part outer surface is formed with wrom tooth wheel (ウ オ one system ギ ア) 72a, is engaged with worm gear (ウ オ one system ホ イ one Le) 75 on this wrom tooth wheel 72a.Worm gear 75 ground axle suspensions free to rotate are on gear-box 62, and than it, its center is provided with driving shaft 61 with one heart, and worm shaft 72 rotates and worm gear 75 and driving shaft 61 are rotated.

In addition, on worm shaft 72, and form flange portion 72b near the end of swivel 71 banded sides the outer surface.The end face elasticity of swivel 71 sides of this flange portion 72b is pressed over an end of the disc spring that becomes elastomer 64.On the other hand, the other end of disc spring elasticity under the state of the inside of swivel 71 slotting overall springs is pressed on the wall of gear-box 62.Thus, worm shaft 72 is towards the direction of leaving from motor 60 and by elastic force-applying.

If motor 60 rotates, then worm shaft 72 rotates by swivel 71 in said structure, and worm gear 75 rotates, and the part that meshes with worm shaft 72 moves to the direction of leaving from motor 60.Usually, worm shaft 72 is extremely left from motor 60 by the power that applies of the disc spring of elastomer 64.And user then makes the part with worm shaft 72 engagements rotate near worm gear on the direction of motor 60 75 if treatment element 2a is exerted pressure.At this moment, worm shaft 72 is resisted the applying power of disc spring of elastomers 64 and is moved, so by measuring this displacement, can calculate the body pressure that is subjected to user according to the spring performance of this displacement and elastomer 64 (disc spring).

The displacement of elastomer 64 can come indirect determination by the displacement of being measured worm shaft 72 by extensometer.In the present embodiment, as shown in figure 20, the space detection bodies 76 that forms flange-like is set on the end of the opposition side of the motor 60 of worm shaft 72, simultaneously be equipped with on the gear-box 62 can detect and this space detection bodies 76 between the space pick off 65 noncontact extensometers such as (for example) eddy current types in space (distance).

Like this, body pressure can be calculated by the displacement in the space between the space detection bodies 76 of measuring space pick off 65 and worm shaft 72.Use space pick off 65 can realize miniaturization and on the extensometer, but also be not such contactless of space pick off 65, utilize variable-resistance structure (for example potentiometer) and be to use as extensometer.In this case, can prevent to be subjected to electromagnetic noise etc. disturbs and produces error.Like this, use the gear train in the gear-box 62 of second drive division, only form pressure detecting portion, so compare with the situation that is assembled with a plurality of parts, equipment by few parts such as elastomer 64, extensometer are set, can reduce component count, can also have the advantage that reduces error simultaneously.

In addition, available above-mentioned pressure detecting portion 98 is judged the shoulder position of the user on the backrest is following.

In the present embodiment, the middle position of the position of the treatment element 2a during with the last reference value, time reference value that detect the body pressure of treatment element 2a is judged as shoulder position.That is, slowly treatment element 2a is pressed to human body by second drive division, then the body pressure that is thereupon detected by pressure detecting portion 98 increases.And, detect body pressure when becoming predefined down reference value treatment element 2a to the extrusion position (being the angle of rotation of gear plate 30 in the present embodiment) of the direction of pressured human body.Equally, detect body pressure become predefined when going up reference value treatment element 2a to the extrusion position (angle of rotation of gear plate 30) of the direction of pressured human body.And, the middle position of this extrusion position is judged to be the position of shoulder.And, having the front face of the backrest 92 that forms by cloth, skin etc. in the actual masseur at the front side of treatment element 2a, treatment element 2a is pressured human body by this front face, so even there is not user on the backrest, also can how much detect pressure.Therefore, as following reference value, under this state, configure the depended on pressure of pressured front face.In addition, as last reference value, configure the depended on pressure not excessively upward restriction of the scope of (do not bring pain) of treatment element 2a to human body.Therefore, detect the height of central authorities' judgement of the height of reference value on this and the height that detects following reference value as shoulder.

In addition, the stroke of the worm shaft 72 that is moved by body pressure is obtained setting according to the spaces in the gear-box 62, can use the roughly whole zone of the trip, effectively measures the following reference value of setting body pressure, goes up reference value.In addition, from increasing the body upper limit of pressure that to measure, the viewpoint of scope in the lower limit, the most handy non-linear spring.For example, closely adorn the different a plurality of linear spring arranged in series of load that presses up to being compressed and become under the situation of non-linear spring, closely adorn pressure up to initial spring, all springs are compressed, after initial spring was closely adorned pressure, its remaining spring was compressed.With compare at first because spring constant (being the load of specific compression) becomes big, become big so spring constant is interim later on.Thus, but precision is measured the load of lower primary school well, and can be measured to the load also littler than the lower limit of the existing loading range that is measured to, and also is effective for the light user of body weight.On the other hand, obtain with a plurality of spring arranged in series and the characteristic of inverted configuration, also effective for the user of heavyweight vehicle.

In above-mentioned control, whether the position of treatment element is positioned at high position, portion position shoulder to shoulder, can judge by being compared by the detected shoulder position in position and shoulder position testing agency as position sensor detected (upper side) the treatment element 2a of treatment position of components as described above testing agency.

In the above-mentioned masseur, uphold actuator A1 and make the treatment element 2a that is arranged above and below, the interval variation of 2b, so not only catch human body, and can thereby for example when kneading massage, make pushing of user be felt to change by with the fixing interelement distance of treatment of predetermined distance.

In addition, in the foregoing description, from the actuator A1 of axle 100 to second arms 14 the distance of banded point than distance (for example with reference to Figure 13 (A)) from the bolster of the treatment element 2b of axle 100 to second arms 14, so, be less than or equal under the so little situation of the air pressure of 100kPa even be used to uphold the air pump of actuator A1, the treatment interelement also can generate the enough power of pinching of grabbing.In addition, the use of the linear slide guide rail 17 of the rectilinearity extension of support actuator A1 is also effective.

In addition, in the above-described embodiments, when making treatment element 2b with the pressured human body of power F by second arm, 14 rotations of pushing by actuator A1, the first arm 13 backwards rotation owing to the existence of connecting piece 15, treatment element 2a is with the pressured human body of power P (for example with reference to Figure 13 (B)).Therefore, the position of the length of decision arm 13,14 and the point of contact of interlock connecting piece 15, the P that exerts all one's strength for example becomes the relation of 0.7F＜P＜1.3F, then can prevent by treatment element 2a, treatment element arm 12 bigger rotations when 2b grabs and pinches massaging action, and loss power.

In the above-mentioned masseur, as Figure 21 (A) with (B), it is little that lower side treatment element 2b cans be compared to upper side treatment element 2a width most.Particularly, to have 2～3 times difference be effective to both width.The human body shoulder is grabbed when pinching by finger, thumb conflict back side, and the upper face side of other shoulders that refer to conflict can provide the masseur of this point of imitation.

In addition, as the air driven mechanism 95 of the driving usefulness of actuator A1, for example shown in Figure 22 (A), can adopt by natural aerofluxus and carry out aerofluxus from actuator A1, also can be shown in Figure 22 (B), the air inlet by air pump 96 carries out aerofluxus from actuator A1 with forced exhaust.Under the situation of the air driven mechanism of employing Figure 22 (B), the action that can sow discord treatment element 2a, 2b more reliably.In addition, provide under the situation of massaging action, preferably make the speed of the air inlet that deflated velocity ratio is used to uphold fast.

And then, in the above-described embodiments, as shown in figure 23, according to by pressure detecting portion 98 detected pressure signals, to at least one of first drive division, second drive division, the 3rd drive division, the 4th drive division (actuator A1) and force application mechanism (actuator A2), at least one of its position and speed carried out feedback control by control part 8, thereby the load pressure of treatment element arm 12 can be predefined load pressure always.

(embodiment 2)

The massager structure with above-mentioned first embodiment is identical basically except following point for the masseur of present embodiment, and multiple part is omitted explanation, gives the Reference numeral identical with first embodiment to same structure simultaneously.

In the present embodiment, shown in Figure 24 and 25, a side receiving plate 20 of grabbing the actuator A1 that uses when pinching massaging action is arranged on second arm 14, and simultaneously, the receiving plate 21 of opposite side is installed on the treatment element arm 12.The receiving plate 24 of the side of actuator A2 is installed on the connecting piece 45 in addition, and the receiving plate 25 of opposite side is installed on the treatment element arm 12.These actuators (A1, A2) are driven by air driven mechanism 95 equally with first embodiment.In addition, disc spring (twist with the fingers り コ イ Le ば ね: not shown) is stirred in configuration between second arm 14 and treatment element arm 12, to the direction of the interval broadening of treatment element 2a, 2b by elastic force-applying.

In above-mentioned structure, shown in Figure 26 (A) and 26 (B), uphold actuator A1, then second arm, 14 opposings of force application mechanism 1 are stirred the power that applies of disc springs and pressured and be the center direction rotation of arrow D2 in the drawings with axle 100 by actuator A1.Meanwhile, making the first arm 13 by interlock connecting piece 15 is that rotate on reverse D1 at the center with axle 101.Thus, the treatment element 2a, the 2b that are located on the arm 13,14 are approaching mutually, and massaging action is pinched in grabbing that the treatment element about obtaining utilizing carries out.On the contrary, from treatment element 2a, the approaching state of 2b and under the situation about leaving mutually, air bag 22 is carried out aerofluxus get final product.

On the other hand, uphold actuator A2, then treatment element arm 12 is that forwards rotate at the center with axle 100, and treatment element 2a is forwards moved.In addition, by the actuator A2 that works as air spring to treatment element arm 12 elastic force-applyings.Thus, grab when pinching massaging action aforesaid, the treatment element 2a of the upper face side of contact shoulder rearward escapes in the time of can preventing to grab the shoulder of pinching human body, pinches massage so can above-mentionedly more reliably grab.In addition, apply on the direction of power in opposing treatment element 2a is applied when making actuator A2 dwindle the size loads of such degree, treatment element 2a retreats on the rightabout of the D1 of Figure 26 (B), so also superior on security performance.In addition, under the situation of present embodiment, what have the first arm 13 of treatment element 2a and treatment element arm 12 and second arm 14 with treatment element 2b shakes that also the structure with first embodiment is identical on the action this point under the state that becomes the restriction of bearing actuator A2.

In the control when masseur of present embodiment is characterised in that the interval variation of treatment element 2a, 2b of above-below direction.Promptly, as shown in figure 27, under the approaching mutually state of treatment element 2a, 2b on the back surfaces of user, drive actuator A1 and making under the situation that the treatment element leaves mutually, cooperate this departure motion, make the motor 50 of first drive division, treatment mechanism 3 integral body that contain treatment element 2a, 2b are moved downwards.Under the state of Figure 27, by reason described later, up and down among treatment element 2a, the 2b treatment element 2a of upper side on the direction that the treatment element spacing broadens, move this structurally can be described as difficult.Therefore, treatment mechanism 3 carries out the action of the treatment element 2a of the auxiliary upper side of change in location downwards.Particularly, as shown in figure 28, carry out the deflated while opening to the outside in the air bag by air driven mechanism 95, the motor 50 that drives first drive division is depressed treatment mechanism 3 integral body downwards, thereby on the direction (top among the figure) of the action (first wall 13 is the rotational action of side upward) that promotes to make the first arm 13 to broaden upward, from user bearing object pressure (counteracting force F) with treatment element 2a.

At this, it structurally is difficult moving on the direction of widening the treatment element spacing, and treatment element 2a, 2b up and down which this is meant, followingly judges.Promptly, in Figure 27, to the center of the treatment element 2a of upper side and support its banded straight line L1 of center of rotation of first wall 13 and the backrest face S of back-rest 90 between the angle [alpha] that forms and with the center of the treatment element 2b of lower side and support its banded straight line L2 of center of rotation of second arm 14 and backrest face S between the angle beta that forms compare.(α in the present embodiment＞β), therefore, it is difficult that the treatment element 2a that judges upside moves on the direction of widening the treatment element spacing for above-mentioned angle [alpha] among treatment element 2a, the 2b, a side that β is big.Above-mentioned angle [alpha], β structurally are predetermined, so the first arm 13 that angle [alpha]＞90 ° have a treatment element 2a in illustrated embodiment is particularly widened difficulty, the auxiliaring effect height that move the below of force application mechanism upward.

In addition, in the present embodiment, the action of the location change of treatment element 2a, 2b was as above carried out when only the interval of treatment element 2a, 2b broadened, when the interval of treatment element 2a, the 2b that leaves mutually narrows down, also can make force application mechanism in treatment element 2a, 2b on the structure near a difficult side shifting, auxiliary treatment element spacing is regulated.In addition, on the narrow direction of treatment element spacing, move structurally difficult among treatment element 2a, the 2b up and down which of being meant, can similarly be predetermined with above-mentioned from the contrast of angle [alpha], β.

If the situation that relatively the treatment element spacing narrowed down and broadens, then under the situation that the treatment element spacing fully can not be broadened, may after the masseur action in that the treatment element spacing is broadened is difficult.Particularly, situation as Figure 27, angle [alpha]＞90 °, then under treatment mechanism 3 immobilized states, make in the first arm 13 rotations and the increase treatment element spacing, need user forwards be released in this wise action by treatment element 2a, in the masseur treatment element 2a like this action be actually difficulty.Therefore, bright as mentioned above, increase under the situation of treatment element spacing, the location change of carrying out treatment mechanism 3 promote upper side treatment element 2a to move in the reliable change that realizes the treatment element spacing be ideal.In addition, if the treatment element and come up and down beyond direction on, then can be to direction side by side, the mobile of treatment element assist in the location change action of other drivings beyond combination drives up and down.

The modification of present embodiment is described with reference to Figure 29.Under treatment element 2a mutually approaching under the state shown in Figure 29, situation that 2b leaves mutually, the magnitude relationship of above-mentioned angle [alpha], β is α＜β, thus among treatment element 2a, the 2b treatment element 2b of lower side to move on the direction that enlarges the treatment element spacing structurally be difficult.Therefore, in this case, make in the air bag to open by air driven mechanism 95 and carry out the deflated while to the outside, drive (drive up and down with) motor 50 of first drive division and treatment mechanism 3 integral body be moved upward, thus the direction (below among the figure) of the action (action that second arm 14 rotates to the lower side) of widening in second arm, 14 downward directions that promote supporting treatment element 2b upward treatment element 2b from user reception body pressure (counteracting force).

In addition, moveable block shown in Figure 29, the moveable block with the foregoing description on following point is different.That is, shown in Figure 30 (A) and 30 (B), do not use kowtow hit plate 11 and and treatment element arm 12, and directly axle is contained in the first arm 13 with treatment element 2a and second arm 14 with treatment element 2b is rotated around same axle 100.In addition, actuator A1 is situated between and is located at 14 on the first arm 13 and second arm, and actuator A2 is situated between and is located between connecting piece 45 and the first arm 13.

In this moveable block 4, uphold actuator A1, then shown in Figure 30 (B), at first, only second arm 14 rotates, and treatment element 2b is near treatment element 2a side.In should moving, treatment element 2b such as contacts at the rotation that hinders second arm 14 with user, and then the first arm 13 is followed the extension of actuator A1 and rotated on the close direction of second arm 14, and treatment element 2a is near treatment element 2b side.

Therefore, in the present embodiment, also control second drive division (motor 60), strengthen massage intensity, then can carry out from top and grab the massaging action of the shoulder of pinching user behind.In addition, if weaken massage intensity, then the fore-and-aft direction position (overhang) of treatment element 2a, 2b is roughly the same, and if this state is down change treatment element spacing up and down, then can provide the back of user tactility with by the different massage of pressure sensitivity.

(embodiment 3)

The masseur of this enforcement is characterised in that to be used to provide effectively grabs the control of pinching massaging action, the massager structure with above-mentioned first embodiment is identical basically except following point for masseur, multiple part is omitted explanation, gives the Reference numeral identical with first embodiment to same structure simultaneously.

Promptly, the moveable block 4 of the treatment mechanism 3 of present embodiment, as shown in figure 31, do not use to kowtow and hit plate 11 and treatment element arm 12, and directly axle is contained on the arm substrate 10 and the first arm 13 with treatment element 2a and second arm 14 with treatment element 2b are rotated around same axle 100.In addition, actuator A1 is situated between and is located between the first arm 13 and second arm 14, and actuator A2 is situated between to be located between connecting piece 45 and the first arm 13.Connecting piece 45 with kowtow the driving shaft 41 that hits massage usefulness and link.Dispose between the first arm 13 and second arm 14 and stir disc spring (not shown), elastic force-applying on the direction of widening at the interval of treatment element 2a, 2b.

In moveable block 4, shown in figure 32, the action under the state that shakes the restriction that becomes receiving actuator A2 of the first arm 13 and second arm 14.That is, externally under the opened state, the first arm 13 and second arm, 14 limits are shaken the flexible limit of actuator A2 in the inner space of the air bag 26 of actuator A2.In addition, when actuator A2 air feed being made it uphold, actuator A2 provides elastic force-applying to retreating of treatment element 2a.Connecting piece 45 links with the first arm 13, but axle 48 by be located at the first arm 13 on slotted hole 49 engage and do not hinder above-mentioned shaking.The first arm of expression present embodiment and the axonometric chart of second arm among Figure 33 (A) and 33 (B).

In above-mentioned moveable block 4, actuator A1 is upheld, then as shown in figure 34, second arm 14 rotate and treatment element 2b to treatment element 2a side shifting.In addition, as shown in figure 35, if uphold actuator A2, then the first arm 13 and second arm 14 rotate on the direction shown in the arrow.In addition, actuator A1 is upheld, grab when pinching massaging action, actuator A2 is upheld, then as shown in figure 36, pinch massaging action and make under the state that the treatment element spacing narrows down for grabbing, two sides' treatment element forwards moves up and down.

In addition, only treatment element 2b is being driven on the near direction of treatment element 2a side joint by the extension of actuator A1, but in should moving, treatment element 2b contacts with user etc. and hinders the rotation of second arm 14, then the first arm 13 sides with the extension of actuator A1 with the approaching direction of the first arm 14 on rotate, treatment element 2a is near treatment element 2b side.Therefore, but good reliability ground carry out to grab and pinch massaging action.In addition, by second drive division massage intensity is under the situation of weak state, the fore-and-aft direction position (overhang) of treatment element 2a, 2b is roughly the same, so can obtain from the action of the back surfaces of catching the user on the backrest up and down.On the other hand, massage intensity is under the situation of strong state, and treatment element 2a is positioned at front side, so make the shoulder of the pressured user of treatment element 2a from the top, makes the spine of the pressured user of treatment element 2b simultaneously from the below, pinches massaging action thereby can realize grabbing.In addition, grab when pinching massaging action, uphold actuator A2 as shown in figure 36, thereby treatment element 2a is difficult to escape owing to be subjected to the body pressure of user, can effectively be grabbed and pinch massaging action.

The masseur of present embodiment is pinched massaging action for carrying out above-mentioned grabbing more reliably, the following driving control of carrying out actuator A1, A2.That is, as shown in figure 37,, be pressed into shoulder by the air spring power of actuator A2 from the top by the treatment element 2a of upper side at first by making actuator A2 uphold (T1), the first arm 13 and second arm 14 are forwards rotated.Afterwards, uphold (T2) by making actuator A1, the treatment element 2b that makes lower side begins to grab the action of pinching shoulder near treatment element 2a.During both extensions that make actuator A1 and actuator A2, the rotation of the treatment element 2b that gets by the extension that utilizes actuator A1, thereby make the pressure that contacts between contact pressure ratio treatment element 2a and the user between treatment element 2b and the user, then as previously mentioned, treatment element 2a rotates towards treatment element 2b side.Therefore, can the reliability highland grab and pinch massaging action.In addition, under the state of the pressured shoulder of treatment element 2a, make treatment element 2b,, provide reliably and effectively grab and pinch massage so treatment element 2b picks up trapezius muscle near treatment element 2a side.In addition, grabbing the release of pinching do is (T3) that carries out from the aerofluxus of two actuator A1, A2 by beginning simultaneously.Among Figure 37, T4 represents that the air pressure of actuator A1 and actuator A2 is zero, and T1～T4 grabs a circulation of pinching massaging action.In addition, Figure 38 is the ideograph that the above-mentioned interlock of grabbing the treatment element 2a, the 2b that pinch massaging action of expression is done.

In example shown in Figure 37, in the moment of postponing required time Td from the moment of the extension of beginning actuator A2, begin to make actuator A1 to uphold, but as shown in figure 39, pressure transducer S3, the S4 of the air pressure that detects in actuator A1, the A2 are set, as shown in figure 40, also can be moment of setting to begin the extension of actuator A1 in the difference of the blow gas pressure Vi of mensuration pressure Vo in the actuator A2 and actuator A2.In this case, begin near treatment element 2a with the moment treatment element 2b that the pressure of stipulating is pressed into shoulder, pinch massaging action so can further obtain effectively grabbing at treatment element 2a.

Massaging action is pinched in grabbing of above-mentioned actuator A1, A2, at least one of the adjusting of the overhang (massage intensity) of the location change of (width) direction, treatment element about the driving up and down of the enforcement body that first embodiment also capable of being combined describes in detail, treatment element.As an example, below be presented in the situation of pinching the action of these drive divisions of combination on the massaging action of grabbing.

Grab and pinch massaging action and be positioned at the more state of top of portion position shoulder to shoulder from treatment element 2a.As shown in figure 41, at first, when upholding actuator A2, control the 3rd drive division, the interval on the left and right directions of treatment element is diminished, control first drive division simultaneously force application mechanism 3 is moved downwards.In addition, control second drive division, moveable block 4 is rotated so that massage intensity becomes strong state.Then, (or the below of force application mechanism moved to the moment of assigned position or arrived moment of assigned position in the overhang of treatment element the moment that obtains setting at the interval of the left and right directions of treatment element, the moment of the massage intensity of arrival regulation promptly) begins to uphold actuator A1 (T1), afterwards, make the interval of the left and right directions that dwindles the treatment element action, action that force application mechanism moves downwards and the action of regulating massage intensity are all reversed (T2), these move moment release actuator A1, the A2 (T3) that arrives the target location.T4 represents that the air pressure of actuator A1 and A2 is zero state, and T1～T4 grabs a circulation of pinching massaging action.

At this moment, can provide simultaneously from the neck root of takeing on neck and sandwich the interelement action of treatment and be pressed into the action of shoulder by treatment element 2a.In addition, treatment element 2b is managed by each pick off near the position of user, then can obtain the good ideal massage position of repeatability by the driving of actuator A1.In addition, also can effectively prevent from dangerous play is carried out in positions such as bone and cervical region.

Utilizability on the industry

As mentioned above bright, according to the utility model, in existing kneading massage, friction massage, knocking On the basis of massage etc., provide by treatment element up and down neck is grabbed the massaging action of pinching, logical Cross and make up them or use separately, can provide each user's satisfaction high massage effect. In addition, logical Cross suitably control be used for providing grab pinch massaging action drive division, thereby can be to user's shoulder Apply excessive depended on pressure, and securely and effectively provide massage to user's shoulder. Like this, originally Utility model is as providing the massager of the abundanter massaging action of kind can expect to utilize widely.
