The specific embodiment

As shown in Figure 1, nothing pad pad 1 is made of the laminate 6 that comprises elastic pad 4 and low bounce-back pad 5, forms pad M with lid C covering.Aforementioned pad M as Fig. 9, shown in Figure 10, has the pad mounting surface 3 of several bends of matrix Bb W by being disposed at, and can together form bed with aforementioned bed matrix Bb.

Aforementioned bed matrix Bb, in this example, be have the plane of not having the bed skeleton and being provided with feet L slightly become rectangle bed pedestal B6, support aforementioned bed pedestal B6 and a support portion B1 who forms continuously towards sufficient side from a side, the back of the body support portion B2, stern support portion B3, leg support portion B4 and pin support portion B5.And, by the surface to B5, can form pad mounting surface 3 from aforementioned support portion B1.

The formation of aforementioned bed matrix Bb is the bed half matrix Bb1 that makes a side and sufficient side, and Bb2 is an end of combination in opposite directions, in horizontal development one-tenth deployed condition as shown in Figure 9, and between the anti-V font plumbness as shown in figure 11, can link on folding expansion ground.Therefore, in aforementioned plumbness, pad mounting surface 3 also forms anti-V font, so, in bed half matrix Bb1, in the Bb2 upper end, form slightly rectangular folding bend W4.

In aforementioned deployed condition, as shown in figure 10, sufficient side end props up the aforementioned back of the body support portion B2 of a pedestal B6 in the first pivot point P1 pivot, by the arm 12 that circles round that drives with driver 11a, can form and make the past heeling condition that tilts of a side.At this moment, be formed with the W1 of oblique bending portion of past interior bending between back of the body support portion B2 and stern support portion B3 in aforementioned pad mounting surface 3.And a support portion B1 is pressed also outline height of the aforementioned back of the body of height ratio support portion B2 with the arm 12 that circles round, and forms a propradation H.

In addition, aforementioned leg support portion B4, side end props up with the second pivot point P2 pivot in bed pedestal B6, parallel linkage is with aforementioned leg support portion B4, in pin support portion B5 that aforementioned leg support portion B4 props up with the 3rd pivot point P3 pivot, across support link 14 and the aforementioned second pivot point P2 between aforementioned pin support portion B5 and bed pedestal B6 the 4th pivot point P4, and the bed pedestal B6 between P4 constitutes.And when driver 11b when elongation that is across between a pedestal B6 and pin support portion B5, leg support portion B4 makes sufficient side toward tilting, and simultaneously, pin support portion B5 keeps level and forms the state that foot rises.At this moment, be formed on the leg bend W2 of past interior bending between stern support portion B3 and leg support portion B4, and be formed on the hollow of the knee pars convoluta W3 of past outside sweep between leg support portion B4 and pin support portion B5 in aforementioned pad mounting surface 3.

Aforementioned Body without cushion 1, as previously mentioned, by comprising elastic pad 4 and the laminate 6 that is disposed at the low bounce-back pad 5 above or below the aforementioned elastic pad 4 that overlaps constitutes with elastic force.Elastic pad 4 and low bounce-back pad 5 can prevent the skew of mutual alignment by the friction on the overlapping face, still, also can be in comprising overlapping face two terminal number places or comprehensively, by then and integrated.Aforementioned laminate 6 in this example, as Fig. 2, shown in Figure 5, forms with 2 dividing bodies of main S of portion and occipitalia T, makes occipitalia T be disposed at a side and inserts in the aforementioned lid C and use.Form by occipitalia T is separated, in aforementioned propradation H shown in Figure 10, the occipitalia T on the support portion B1 is independently risen.As a result, need not make pillow keep comfortable posture in addition, can improve the sleep comfort with regard to improving support user's head.

Aforementioned laminate 6, thickness T a be for example about 40～500mm, and longitudinal length is that the main S of portion adds occipitalia T system for example about 1500～2800mm, and transverse width is for example single to be of a size of about 700～1300mm, half double being of a size of for example about 900～1800mm.Aforementioned occipitalia T longitudinal size is for example about 200～400mm.

Aforementioned elastic pad 4 thickness T b are with respect to laminate 6 thickness T a for example about 25～75%, high resilience.Aforementioned elastic pad 4 by this elastic force positively supporter press, so the user can not feel the bottom of conflicting, can keep the comfortable sleep sensation.

Aforementioned elastic pad 4 as shown in Figure 4, is formed with the bending groove 8 in horizontal expansion in this example, aforementioned crooked each field that cooperates in opposite directions with each the bend W1～W4 that is formed on pad mounting surface 3 of being located at groove 8.That is the distance L 1 in own elasticity pad 4 sufficient side ends toward a side for example is the field at center with the position about 1100～1200mm, forms by several, in this example, by 7 crooked first groove group D1 that constituted with groove 8.And this first groove group D1 becomes in the anti-V font plumbness in bed matrix Bb as shown in figure 11, cooperates in opposite directions with the bend W4 of folding; As shown in figure 10, in heeling condition, cooperate in opposite directions with the bend W1 that tilts.Similarly, the distance L 2 that self-sustaining side end begins is the center with the position about 790～890mm for example, forms the second groove group D2 that cooperates in opposite directions with aforementioned folding bend W4 and leg bend W2; And distance L 3 is the center with the position about 480～580mm for example, forms the 3rd groove group D3 that cooperates in opposite directions with hollow of the knee pars convoluta W3.

So, aforementioned bending becomes in the state of rising in the plumbness of anti-V font, heeling condition and the pin support portion that back of the body support portion B2 becomes to erect with groove 8, pad mounting surface 3 is formed at the field of each bend W of corresponding past interior or past outside sweep, so, result from flexible can being absorbed of elastic pad 4 table the insides, as a result, Body without cushion 1 can not produce and fill up the phenomenon that mounting surface 3 is floated certainly, and can be along 3 distortion of pad mounting surface.And in interior bend, elastic pad 4 inboards can not reduce by elastic force because of compression in W1 of oblique bending portion and leg bend W2 etc., so, can keep dispersion and press.And with respect to the repetition of aforementioned bending and folding action, the stress that elastic pad 4 is produced can be suppressed, and prevents the tired deterioration of elastic pad 4, improves endurance quality.

Aforementioned crooked with groove 8, in this example, as shown in Figure 7, in opposite directions in elastic pad 4 upper and lower surface settings.By this, when flexural deformation, both can both improve morphotropism the inboard compressed side and the tensile side in the outside, and two effects combine and can effectively improve diastrophic ability.

In addition, the bending of this example as shown in Figure 7, has this two recess sidewall 8a with groove 8, the V font 8b of portion that 8a narrows down towards the bottom, and, by being set, curved surface shape bulge 8c forms in the continuous groove that this V font portion 8b lower end is become.By the aforementioned V font 8b of portion, during flexural deformation, can improve the deformability of inboard compression side.In addition,, can improve crooked deformability, simultaneously, can prevent to produce the phenomenon of be full of cracks in bending with groove 8 depths, can improve durability because of repeated deformation by curved surface shape bulge 8c.

Aforementioned crooked with groove 8, preferably making longitudinal pitch p1 is about 10～40mm.Preferably lower limit is more than 20mm, and the upper limit is below 35mm.In less than 10mm the time, too narrow at interval, so cause elastic pad 4 elasticity to reduce, may cause the sensation of the bottom of conflicting; Otherwise when surpassing 40mm, flexural deformation absorbability deficiency so elasticity may reduce in curved interior, in addition, also may produce because the tired be full of cracks that is caused.

It is in 1/7～1/3 scope of elastic pad 4 thickness T b that bending preferably makes the degree of depth with groove 8.In less than 1/7 o'clock, because too shallow, diastrophic absorbability can be not enough; Otherwise when surpassing 1/3, the intensity of elastic pad 4 reduces too many, and the problem of durability deficiency is arranged.

Aforementioned elastic pad 4 in this example, is 100～450N by the hardness according to JIS K6400 gained, and loss coefficient is constituted by 0.05～0.3 sponge material.Its hardness lower limit is preferably more than the 150N, and the hardness upper limit is preferably below the 350N.The loss coefficient lower limit is preferably more than 0.1, and the hardness upper limit is preferably below 0.25.When aforementioned hardness during less than 100N, elastic pad 4 elasticity deficiencies are so have the sensation of the bottom of conflicting; Otherwise, when hardness surpasses 400N, the resiliency deficiency, thus in sleep, can feel too hard, and reduce the sleep comfort.When loss coefficient less than 0.05 the time, bounce is too big, so can reduce the sleep comfort; Otherwise when loss coefficient surpassed 0.3, the bounce deficiency was so may have the sensation of the bottom of conflicting.

And so-called loss coefficient is when material deformation, and the numerical value that the energy of which kind of degree is sponged by changing over heat is measured with the dynamic viscoelasticity determinator.In addition, loss coefficient is cut off spring rate G ' and loss with storage and is cut off spring rate G " ratio, G "/G ' represents, the numerical value big expression of healing can absorb the more energy.Again, constitute the sponge material of aforementioned elastic pad 4, in this example, use polyurethane foam plastics.Aforementioned sponge material also can use polyethylene foam plastics etc.

Aforementioned low bounce-back pad 5 as mentioned above, forms laminate 6 with the elastic pad lamination, with respect to laminate 6 thickness T a, for example has the thickness T c about 25～75%.Aforementioned low bounce-back pad 5 as shown in Figure 6, in order to improve aeration, is provided with a plurality of passages 7.The diameter of aforementioned passage 7, in 3～12mm scope, lower limit is preferably more than the 5mm, and is preferably more than the 6mm; The upper limit is preferably below the 10mm, and is preferably below the 7mm.In less than 3mm the time, the aeration deficiency, thus can't press dispersive property insufficient by body, and the moisture that distributes from health might be detained; Otherwise when surpassing 12mm, low bounce-back pad 5 might intensity reduce.

The longitudinal pitch P2 of aforementioned passage 7, in 15～45mm scope, lower limit is preferably more than the 25mm, and the upper limit is preferably below the 35mm.In addition, aforementioned lateral pitch P3, in 10～40mm scope, lower limit is preferably more than the 20mm, and the upper limit is preferably below the 30mm.When longitudinal pitch P2 and transverse pitch P3 respectively are during less than 15mm and less than 10mm, too little at interval, so can't obtain the effect that dispersion is pressed; Otherwise, when longitudinal pitch p2 and transverse pitch p3 respectively when surpassing 45mm and surpassing 40mm, venting capability can be not enough.

Aforementioned posture change such as stand up is accompanied by body weight toward laterally moving, so, press in body to distribute, mainly represent with the variation in laterally.Therefore, in this example, promptly follow the trail of aforementioned body for acumen and press changes in distribution and the dispersion pressure, institute is so that longitudinal pitch p2 also will be greatly with transverse pitch p3.

The per unit area of aforementioned passage 7 (m2) quantity is in 600～1600 scopes.Lower limit is preferably more than 900, and the upper limit is preferably below 1450.When less than 600, the venting capability deficiency is pressed the tracking that changes so lack for body; Otherwise when surpassing 1600, passage is overstocked, thus can't obtain the effect that abundant dispersion is pressed, and also intensity might reduce.

And, aforementioned passage 7, even be located at the lateral ends next door of low bounce-back pad 5, body presses dispersion effect very poor, and, can reduce the intensity of this part.Therefore, in this example, as shown in Figure 3, in for example transverse width 50～120mm left and right sides scope of 5 liang of lateral ends of low bounce-back pad, make the field Z that does not form passage 7.

So, by forming passage 7, the low bounce-back pad 5 that improves venting capability can improve the deformation performance that corresponding body is pressed.As a result, as shown in Figure 9, the field in the heavier outstanding places of body weight such as supporting head part, shoulder and buttocks is deformed into the shape of corresponding build for flexible support, presses and supports by dispersion, can obtain good sleep comfort.Particularly stand up etc. and body is pressed and distributed when changing,, can follow the trail of aforementioned body in the short time and press and change and be out of shape by the effect of passage 7 when following, so, can be for a long time equably supporter press.As a result, make and posture change such as stand up and carry out swimmingly, simultaneously, feel with the softness of surrounding whole healths and to support, so, can significantly improve the sleep comfort, promote simultaneously to sleep peacefully and the systemic blood circulation, can improve health.And, comprising the above-mentioned action of standing up, body is not pressed and can be disperseed partially on one side, and comprising the outstanding place of bones such as scapula portion and celestial osseous part can both be flexibly supported, so, even long-term bed also can prevent bedsore.By high venting capability, the moisture that distributes from health in the sleep can not be detained and evaporate, so even summer, comfortable sleep also can secure good health.And the foul smell composition of low bounce-back pad 5 inside is dispersed fast and is reduced from passage, so, do not have pungent stink in the sleep and produce discomfort.

In addition, aforementioned low bounce-back pad 5 is 35～180N by the hardness according to JIS K6400 gained in this example, and loss coefficient is constituted by 0.3～0.95 sponge material.Its hardness lower limit is preferably more than the 50N, and the hardness upper limit is preferably below the 130N.The loss coefficient lower limit is preferably more than 0.45, and the hardness upper limit is preferably below 0.8.When aforementioned hardness during less than 35N, low bounce-back pad 5 bodies press support force not enough and produce unstable sense, can damage the sleep comfort; Otherwise when hardness surpassed 180N, because the shortcoming flexibility can reduce the sleep comfort, and the body pressure can become inhomogeneous, can produce the situation of poor circulation in the sleep, and bedsore might take place.When loss coefficient less than 0.3 the time, the too big and dispersion of bounce is pressed insufficient, so can reduce the sleep comfort, causes the outbreak of poor circulation and bedsore; Otherwise when loss coefficient surpassed 0.95, so the bounce deficiency was can the anaesthesia sense of stability in the sleep.And, constitute the sponge material that hangs down bounce-back pad 5, in this example, be the use polyurethane foam plastics.Aforementioned sponge material also can use polyethylene foam plastics etc.

And, between aforementioned low bounce-back pad 5 and elastic pad 4, as shown in Figure 8, stiffening plate 13 can be set.At this moment, can improve body and press support force, simultaneously,, can strengthen fatigue strength for the alternating bending action.Aforementioned stiffening plate 13, in this example, reticulate body N again, also can be located at elastic pad 4 outsides.Aforementioned reticulate body N, it is netted to use the line of the monofilament of plastics such as polyethylene, polystyrene, ABS resin, vinyl chloride resin and three chlorocyanamide resins or twisted filament etc. to be woven into, and cross part with hot melt or being combined into one such as solid and forming.
