And, even in to be contained in the massage machine that lower limb loosens in the portion 6 very heavy, also can be with elastic cylinder 18 to action bars 10 to clockwise direction (lower limb is loosened the direction that the portion 6 lifts) application of force, so, for lift lower limb loosen portion's necessary operations power can be very little, can easy manipulation.

When the folding and unfolding lower limb loosens portion 6, action bars 10 is rotated to counter-clockwise direction, connecting rod A13 antagonism elastic cylinder 18 is also rotated to counter-clockwise direction, and lower limb loosens portion 6 and is packed up as shown in Figure 1.Under this folding and unfolding state, 21 of the junction points of the upper end of elastic cylinder 18 and force application rod 17 are in the position of top a little of the connecting line of operating axis 12 and elastic cylinder 18 lower end axle fulcrums 20, so force application rod 17 is to the counter-clockwise direction application of force, like this lower limb is loosened portion 6 to packing up the direction application of force, lift without elastic cylinder.

And, a pair of about connecting rod A13 and connecting rod B14 are configured to, when lower limb being loosened portion 6 when lifting, owing to support with such pair of right and left connecting rod A13, B14, even it is very heavy that lower limb loosens portion, only be placed on a side partially even be placed on the lower limb that lower limb loosens portion, the lower limb portion that loosens can not tilt yet and support along level.And these connecting rods A13, B14 also play the potentiation that lower limb is loosened portion's framework 8.

Below, lower limb is loosened portion 6 inside describe.

Lower limb loosens portion's framework 8, and the shape of seeing from the place ahead sectional flute profile as shown in Figure 3 has integrally formed guide rail 25 as basic configuration at its both ends, left and right sides.The rearward end of this guide rail 25 is propped up on seat portion framework 7 by aforementioned axis 9 earth's axis free to rotate.Support chip 27 and the lower limb turned up downwards at the left and right horizontal face 26 that loosens portion's framework 8 from lower limb loosen between the left and right side of portion's framework, and the described axle 16 that axle is propping up the other end of described connecting rod B14 is housed.

In the outside that such lower limb loosens the described guide rail 25 on portion's framework 8, for guide rail 25 is held together, the コ font and the sliding part 29 at the two ends, the left and right sides of bedframe 28 are chimeric.Sliding part 29 can upwards slide in front and back along guide rail 25.Slide for when sliding, being easy to, between sliding part 29 and guide rail 25, sandwiched the pad of doing with the Du Laite resin 30,31.Pad 30 is installed in guide rail 25 1 sides, and pad 31 is installed in sliding part 29 1 sides.

In addition,, between sliding part 29 and guide rail 25, be provided with fixed mechanism, make sliding part 29, be and make bedframe 28 can be fixed on the optional position of fore-and-aft direction though do not show among the figure.If the fixed mechanism releasing is fixing, bedframe 28 just can slide along fore-and-aft direction.

On bedframe 28, the massage assembly 32 with feature of the present invention is housed.

Below, the structure of this massage assembly 32 is described.Motor and power drive mechanism as massage assembly 32 drive sources are installed on the sliding panel 33.Sliding panel 33 can be slidably mounted on the described bedframe 28 along fore-and-aft direction.

If be elaborated, it is bedframe 28, very big rectangle place at central part offers opening 34, on about this opening 34 mouthful of edge, have up and down along the Qi Kou edge sliding panel bearing 35 and sliding panel briquetting 36 are installed with gap, the both ends, the left and right sides of sliding panel 33 are sandwiched in the gap of sliding panel bearing 35 and sliding panel briquetting 36, can slide with respect to 35,36.For the both ends, the left and right sides that make slide plate 33 are easy to slide, sliding panel bearing 35 and sliding panel briquetting 36 usefulness Du Laite resins are made.What sliding panel 33 made progress in front and back is mobile by travel mechanism described later realization.

At the downside of sliding panel 33, be fixed with pair of right and left installing rack 37, on this installing rack 37, motor 38 is installed.Be fixed with as shown in Figure 4 small belt pulley 40 at axle 39 the end of motor 38.The axle 43 of the big belt pulley 42 that is connected with this small belt pulley 40 by belt 41 passes a pair of installing rack 37,37 and is supported on this installing rack 37,37 with axle free to rotately.Giving prominence on these both ends of 43 in installing rack 37,37 outsides, fixing eccentric body 44 respectively with respect to eccentric shaft, axle is propping up crank body 45 on these eccentric body 44 peripheries.

Between than the installing rack 37,37 of motor 38 in the place ahead one side, parallel with large belt wheel 43 with axle 39, fixed axis 46 passes installing rack 37,37 and is fixed in the above.Give prominence on the both ends in installing rack 37,37 outsides at this fixed axis 46, axle is propping up an end of swing arm free to rotate 47 respectively.Swing arm 47, its free end is outstanding upward from the hole 48 that is arranged on the sliding panel 33, and axle is propping up the central part of giving as security template jack back 49 on this outstanding free end.

This jack back 49, from Fig. 4, can obviously find out, be with central authorities the axle branch 50 be the center forwards, backwards direction extend into the signature template, on the both ends of front and back extension, fixing outside installation shaft 51, on this installation shaft 51, as shown in Figure 3, be equipped with free to rotate and beat piece 52 as massage elements.Can see that from above explanation jack back 49 is arranged to pair of right and left, be installed with in the front and back of each jack back 49 and beat piece 52, have 4 so beat piece 52 1.

The central part of described swing arm 47 is connected with described crank body 45 usefulness bars 53.Swing arm 47 1 sides of this bar 53 are connected with swing arm by ball-and-socket joint 54, and other crank body 45 1 side rotational support are picked up the ears on 55,55 the fulcrum 56 passing give prominence to from crank body 45 a pair of.

Between described jack back 49 and described swing arm 47, being provided with maintenance jack back 49 is the maintenance balanced controls of equilbrium position in the raw, center with axle branch 50.This keeps balanced controls, as shown in Figure 8, is made of the spring members 57 of wire.An end 58 of this spring members 57 is inserted in the groove 59, and it is proper, and to hold bending, sweep to be inserted in the hole that is arranged on the swing arm 47 fixing.The 60th,, an end 58 pushes down the bolt of this end for can not deviating from from groove 59.The other end 61 of spring members 57 bends to round shape, is entrenched in the periphery of the post 62 that is arranged on the jack back 49, by the pressing plate 63 that is fixed on the post 62 it can not be deviate from.Here, the other end 61 crooked width H of spring members are smaller a little than the diameter of post 62.With such spring members, can keep jack back under naturalness, to be in and can not meet other local equilbrium position.

In this structure, when motor 38 rotations, make the eccentric body 44 eccentric rotations that are fixed on the axle 43 by small belt pulley 40, belt 41, big belt pulley 42, to rotatablely move by the crank body 45 that is propping up in the periphery of eccentric body 44 and the earth's axis free to rotate and to be transformed into the reciprocating motion shown in the thick-line arrow among Fig. 4 and Fig. 5, because the swing arm 47 that axle props up on fixed axis 46 is connected with crank body 45 usefulness bars 53, the reciprocating motion of crank body 45 is conveyed into swing arm 47, and making swing arm 47 is that the center rocks back and forth along thick-line arrow direction among Fig. 2 with fixed axis 46.Because this shakes, it is that the center is shaken with axis of centres branch 50 also that axle is propped up at swing arm 47 free-ended jack backs 49.

So axle is beaten piece 52 and can be acted on and be placed on lower limb and loosen on the lower limb in the portion 6 jack back 49 rear and front end portions.At this moment, have at interval at fore-and-aft direction,, can massage on a large scale so can beat massage simultaneously to fore-and-aft direction 2 places of lower limb owing to beat piece 52.And, since front and back beat piece 52 about have a pair ofly, can massage simultaneously both legs.

Here, formations such as swing arm 47, bar 53, crank body 45, eccentric body 44, axle 43, big belt pulley 42, belt 41, small belt pulley 40, motor 38 head motion that jack back 49 is shaken.

Because this jack back 49 is by remaining on not and possessing on the equilibrated position of colliding Anywhere in naturalness as the spring members 57 of described maintenance balanced controls, even when lower limb loosens no load condition in the portion 6 it is shaken so be placed at lower limb, can not collide yet, therefore just can not send the sound of collision yet with sliding panel 33.

And, described the other end 61 of spring members 57, owing to make its crooked width H a little littler than post 62, and it seamlessly is entrenched on the periphery of post 62 according to this elasticity, so when jack back shakes, just can not send the abnormal sound that produces owing to the gap between spring members 57 and the post 62.

But as the axle fixed axis 46 of fulcrum of swing arm 47 and the axis of centres branch 50 of jack back 49, wherein axle branch 50 1 sides of jack back are in the top of fixed axis 46 and are positioned at seat portion one side.With this position relation, as shown in Figure 2, loosen in the portion and when jack back 49 is shaken, make lower limb be subjected to the power that direction stretches shown in the picture arrow B from the knee front portion by beating piece 52 when lower limb is placed on lower limb.According to this power, the knee front portion is not to be subjected to from beating the power of piece 52 come-up, promptly is not to be subjected to from beating the power that piece 52 breaks away from, but can beats well by beating piece 52, carries out comfortable massage.

If the relation of the axis of centres branch 50 of described fixed axis 46 and jack back 49 as shown in Figure 9, if axle branch 50 1 sides of jack back are in the top of fixed axis 46 and are positioned at front one side, by beat piece 52 knee front portions shown in arrow C from beating piece 52 come-up, can not beat well.The situation that position relation shown in Fig. 2 is produced just can not appear in contrast therewith.Thick arrow among Fig. 9 has been represented the state that shakes with the same swing arm 47 of Fig. 2.

Below, the installation and the structure of beating piece 52 is elaborated.Beat piece 52 and can free be installed in freely to rotate on the installation shaft 51 of rear and front end portion of jack back 49, it is cylindric that shape is, and made by elastomers such as rubber.As shown in figure 10, be pressed into the sleeve of being made by the Du Laite resin 66 from the both ends open of its center through hole 65 in through hole, this sleeve 66 can slide on installation shaft 51, can rotate freely with respect to installation shaft 51.

Prevent to beat the C type stop ring 67 that piece 52 deviates from and the groove 68 that is provided with promising the inlaying of the front end of installation shaft 51, as shown in figure 11, be pressed into sleeve 66 states to beat piece 52 axial dimension D longer than the size E from installation shaft 51 roots to groove 68.When beating piece 52 when installation shaft 51 is packed into, overcome the elasticity of beating piece 52 and make the amount of its retraction T on direction of principal axis insert installation shaft 51, then with in C type stop ring 67 embedded grooves 68 in case anti-avulsion goes out, so just install.So very close to each other between sleeve 66 and C type stop ring 67, jack back 49 can not send the clicketyclack in shaking.

And, in installation shaft 51 with beat between the piece 52 and to form the length that space 70 determines to be pressed into the sleeve 66 of through hole 65.The elasticity of beating piece can be increased by this space 70, beating of lower limb soft feel can be given.

In general, when both legs being placed on when beating piece 52, both legs can be in open a little laterally state.When by the shaking when beating piece 52 and massage of jack back 49, owing to beat beating both legs and can opening laterally gradually so that massage point is departed from of piece 52, but also can be from beating landing on the piece 52.So, in an embodiment of the present invention, can find out obviously that the external diameter of beating piece 52 is arranged to installation shaft 51 leading sections than root, and in other words the outside is bigger than inboard from Fig. 3 and Figure 10.

According to this structure, can stop both legs to open laterally, and can stop both legs from beating departing from of landing on the piece or massage point.

Beat the shape of piece 52, as shown in figure 12 owing to make it that axial central part depression is installed, also can tissue massage point depart from.Under the situation in the drawings, preferably the external diameter G with the outside does greatlyyer than inboard external diameter F.

As mentioned above, the sliding panel 33 of the drive source motor etc. of massage assembly 32 is housed, can be slidably mounted on the described bedframe 28 at fore-and-aft direction, the slide mechanism to massage assembly 32 describes below.

On sliding panel 33, as shown in Figure 5 and Figure 6, propping up the rotating shaft 71 that makes its rotation by motor 38 through power drive mechanism described later by rear axis, on this rotating shaft 71, install by swingle 72, one end that on this swingle 72, can connect connecting rod 73 with fulcrum 74 with rotating freely, and the other end of connecting rod 73 can be connected on the support 90 that is fixed on bedframe 28 front ends with fulcrum 75 with rotating freely.

The both ends, the left and right sides of sliding panel 33 are clipped in the middle by the set sliding panel bearing 35 in the edge along about the rectangular aperture 34 of bedframe 28 mouthful and sliding panel briquetting 36 and move to stop it to resemble left and right directions, and when rotating shaft 71 rotation, the reciprocating motion of the fore-and-aft direction that swingle 72 becomes sliding panel 33 rotatablely moving by connecting rod 73.Fig. 6 has shown the state that sliding panel 33 moves to rear, and Fig. 7 has shown it and moved to the state of forefront.

Since sliding panel 33 reciprocating motion, it is also reciprocating and change its position along fore-and-aft direction to beat piece 52.So, beat piece 52 by lower limb and make and grant stimulation portion and change along fore-and-aft direction, can prevent because to the disadvantage of the undue stimulation at same place, for example pain or be weary of sense.

And, the thread spindle of direction extension forwards, backwards can be set as making sliding panel 33 along the reciprocating mechanism of fore-and-aft direction, and the nut that screws togather with screw thread with thread spindle is set on sliding panel, the screw thread thrust that motor is produced the thread spindle rotation moves it.Mobile switching in this case, be to detect the mobile boundary of arrival and motor is stopped for the moment by limit switch, and then it is rotated in the opposite direction, even motor stops, but because the inertia of sliding panel also can continue mobile before switching to same direction.Because limit switch can produce the break bounds limit and move, so must set out surplus in the scope that can move.And should consider the situation that limit switch might damage, so be necessary further sliding panel to be restricted, so just can not effectively utilize the space in the scope that can move at arranged outside mechanical braking parts.

But it is as shown in the present, make its reciprocating structure by swingle 72 and connecting rod 73 along fore-and-aft direction, its shift motion is 2 double-length degree of the distance of 74 of rotating shaft 71 and connecting rod 73 1 end fulcrums, can not produce above this break bounds limit more than stroke to move.So can be set in the total travel in can moving range, when the space of limiting in the lower limb portion that loosens is provided with such travel mechanism, can effectively use the space sharply.And owing to do not need limit switch and gag lever post, so price is also cheap.

And in Fig. 6 and Fig. 7, sliding panel 33 is provided with the switch 76 by swingle 72 operation, and this switch 76 is the positions that are used to detect sliding panel 33, rather than in order to detect the limit switch of mobile boundary.To the using method of this switch since with the present invention's it doesn't matter its explanation of Therefore, omited.And, the 91st, for being arranged in the guide plate of sliding panel 33 wire guide, electric wire 92 is by between this guide plate 91 and the sliding panel 33 and handle, can overslaugh sliding panel 33 move back and forth.

Below, the power transmission path of the described rotating shaft 71 of subtend describes.As Fig. 3 and shown in Figure 5, with opposite rotation and that be fixed on the big belt pulley 42 on the described large belt wheel 43 that the output of motor 38 is slowed down, be installed with by the pinion 77 of folk prescription to clutch 78.Folk prescription is to clutch 78, when axle 43 engages with axle 43 when a direction (being called positive direction) is rotated, make pinion 77 rotations that are pressed into its periphery, and when axle 43 (is called in the other direction) rotation round about, do not engage, therefore not to pinion 77 transfer motion powers with axle 43.

Support by installing rack 37 with the axle 80 of the gear wheel 79 of pinion 77 interlocks, extend between the parallel installing rack 37,37 of a pair of and described axle 43, in this stretching, extension place worm screw 81 is housed, with the worm gear 82 of these worm screw 81 interlocks on described rotating shaft 71 is housed, further make rotating shaft 71 rotation of slowing down by worm screw 81 and worm gear 82.The 83rd, the gear-box of interior dress worm screw 81 and worm gear 82 is installed on the sliding panel 33.

According to this structure, when motor 38 when direction rotation (positive rotation), by effect pinion 77 rotations of folk prescription, by above-mentioned power transmission path rotating shaft 71 rotations to clutch 78, its result, above-mentioned sliding panel 33 moves back and forth repeatedly along fore-and-aft direction.Here, motor 38, small belt pulley 40, big belt pulley 42, axle 43, pinion 77, folk prescription has constituted to clutch 78, gear wheel 79, worm screw 81, worm gear 82, rotating shaft 71, swingle 72, connecting rod 73 etc. makes sliding panel 33, promptly beats piece 52 and does the travel mechanism that moves back and forth along fore-and-aft direction repeatedly.

Simultaneously, swing arm 47 also shakes by large belt wheel 43, crank body 45, bar 53, jack back 49 is shaken and massages by beating piece 52.That is, when driving described head motion and beat massage, drive travel mechanism the fore-and-aft direction position of beating piece is changed automatically.

On the other hand, when motor 38 rotates (contrary rotation) round about, do not allow pinion 77 rotate by folk prescription to the effect of clutch 78, sliding panel 33 does not move back and forth yet, just jack back 49 shakes by head motion, beats massage by beating piece 52.

Like this, by selection to the direction of rotation of a motor 38, only drive head motion, can be to beating massage mode at same place, with drive the switching that head motion and travel mechanism make the automatic changing pattern in position of beating massage, as the selection mechanism of these 2 patterns, only the switching by motor 38 direction of rotation gets final product, and can be simple structure.And, because enough motor-driven head motions of energy and travel mechanism, so low price.

But, from textural, when axle 43 when positive direction is rotated, folk prescription closes with being coupling to clutch 78, make pinion 77 rotations of a driven side, if the rotation of the pinion 77 of a driven side is faster than the rotary speed of axle 43, will and axle between produce to slide, promptly produce the first rotation phenomenon of a so-called driven side.Though the decline state before leg placement section 6 forwards descends particularly, it is no problem when sliding panel 33 is rearward mobile, but forwards during a side shifting, the degree that descends forward according to leg placement section 6 also can produce the phenomenon of operation earlier with the motor irrelevant to rotation according to the weight of sliding panel.

And axle 43 even folk prescription is in the state of leaving to clutch 78 with respect to axle 43, also can make the pinion 77 of a driven side rotate slightly to opposite spin by very little friction, moves and make sliding panel 33 produce non-driving.

The both ends of sliding panel 33 are sandwiched between sliding panel bearing 35 and the sliding panel briquetting 36 and slide, move for preventing above-mentioned operation phenomenon earlier and non-driving, as shown in figure 13, on sliding panel bearing 35, fill in sliding panel is carried out arresting braking with rubber spongy cushion 85, by suitably sliding panel 33 being braked with the friction of this foam-rubber cushion 85.

On bedframe 28, as shown in Figure 3 and Figure 4, the drive division guard shield 86 of the synthetic resin of the driving mechanism portion that covers and cover motor 38 etc. is installed.And guard shield 87 above the synthetic resin is installed on bedframe 28.Be formed with opening 88 about on this on guard shield 87, beat piece 52 and be located in this opening 88.The top of guard shield 87 covers with the cuticula with resiliency in the above.

Bedframe 28 can loosen guide rail 25 upwards slip in front and back of portion's framework 8 along lower limb as mentioned above, corresponding to the length of quilt massage person lower limb, its forwards optimal position is stretched out.

Can obviously find out from Fig. 3, surround by the コ font sliding part 29 of bedframe 28 because lower limb loosens the guide rail 25 at the both ends, the left and right sides of portion's framework 8, so bedframe 28 has also played the potentiation that lower limb is loosened portion's framework 8.

And, the assembling that lower limb loosens portion 6 is that driving mechanism portion and massage assembly are assembled on the sliding panel 33, this sliding panel 33 is packed into from the top of bedframe 28 again, again this bedframe 28 is contained in lower limb from the place ahead along guide rail and loosens on portion's framework 8, assembleability is fine.

According to masseur of the present invention, by the driving of head motion, the lower limb that is placed on lower limb and loosens in the portion is beaten massage with the piece of beating on the jack back, so can access by vibrator the good massage effect that can not obtain, can fully remove the fatigue of lower limb.

And, according to another masseur of the present invention, the central part of jack back is equipped with respectively by the axle support and at the both ends of extending along fore-and-aft direction and beats piece, so can beat massage to fore-and-aft direction 2 places of lower limb by enough pieces of beating, can massage on a large scale lower limb.

And, according to another masseur of the present invention, can make jack back not contact any place by balance maintenance mechanism and be maintained on the assigned position, so even jack back is shaken can be owing to noise is sent in contact yet in naturalness.

And, according to another masseur of the present invention, owing to make by travel mechanism and to be arranged on lower limb and to loosen can moving back and forth along fore-and-aft direction with respect to the lower limb portion that loosens of portion to the massage position massage elements of massaging, so also can automatically change along fore-and-aft direction by the position that massage elements stimulated, just can prevent the undue disadvantage that stimulates to same place, for example pain or bored sense, and can massage on a large scale.

And, according to another masseur of the present invention, owing to the reciprocating device with massage assembly is to be made of the bindiny mechanism that rotation connecting rod and rod member make up, so it is mobile that massage assembly can not transfinite, can in the scope that can move, be set at maximum with moving back and forth stroke, be moved back and forth to greatest extent in the space of in lower limb loosens portion, being limited.And, transfinite mobilely owing to do not have, so just do not need to limit the limit switch of moving range, so price is cheap.

And, according to another masseur of the present invention, owing to by travel mechanism its position is changed automatically when can be enough beating piece and beat, so massage effectively in can be on a large scale.

And, according to another masseur of the present invention, owing to can select by the pattern that head motion and two sides of travel mechanism drive to the pattern and the while that only drive by head motion, so user can be chosen in the pattern that beat massage mode and can carry out change in location automatically when beating massage at the same place at massage position by the hope of oneself, can improve use value.

And, according to another masseur of the present invention,,, can reduce cost so can select by head motion and travel mechanism's driving to only driving still by head motion owing to the switching of passing through with a motor its direction of rotation.
