Abstract

Method of producing structural body that functions as seat, backrest, partition, etc., and structural body produced by the method

Description

Seat and backrest, the manufacture method of structure that plays function such as dividing plate and the structure made from this method

Technical field

The present invention relates to structure and manufacture method thereof.In more detail, the present invention relates to have film structural component and make this film structural component form face ground to all or part of film retaining member that is kept of its periphery, have seat or backrest, play the structure and the manufacture method thereof of the face of function such as dividing plate.

(term explanation)

" film structural component " in this specification is to comprise the structure formation intensity of implementing structure (product) and being sought, flexibility or all raw-material " film structural component " of bringing into play the tension force of elastic force, for example comprises reticulate pattern or film or cloth, nonwoven etc.In addition, in this manual, " heat-shrinkable " refers to produce the character of shrinking by heating, and comprise forming the purpose face at least and producing a kind of like this contraction: this contraction produces the tension force that makes the necessary elastic force of structure performance.

Background technology

The Japan Patent spy opens the manufacture method that has disclosed following a kind of structure 101 among the 2001-78852: it has the film structural component that is made of the reticulate pattern thin plate and the film supporting member 103 of frame shape that the periphery of this film structural component is kept, is installed on the framework of chair and plays the seats function.In this manufacture method, as shown in figure 36, at the film structural component 102 that will have heat-shrinkable under the no tension force or with after the also weak tension force of required tension force is fixed on the film supporting member 103 than structure, to be crimped on film structural component 102 from the aluminium sheet 112 after the heating of two sides pressurizes, thus film structural component 102 is heated, film structural component 102 is shunk, give structure 101 tension force, the elastic force that performance is necessary, and form smooth seat surface.

But, in the method, owing to directly being crimped on the film structural component 102 film structural component 102 is heated, so have film structural component 102 fusings or make the reticulate pattern pattern of film structural component 102 produce unequal as its performance of structure of chair and the problem of appearance damage by the aluminium sheet 112 after will heating.

In addition, because of near to or in contact with aluminium sheet 112, so the situation that also has film supporting member 103 also to be heated simultaneously.Therefore, exist film supporting member 103 produce fusing or distortion, as the intensity of chair structure and the problem of performance and appearance damage.Particularly, more to be used as resin such as film supporting member 103 raw-material polypropylene softening because of the heat of lower low-temperature region produces, so easy deformation.

In addition, from ergonomics or attractive in appearance on problem etc., though the situation of seeking seat surface or backrest face etc. is made curved surface is arranged, but film structural component 102 in the past to all the winds roughly expands equably because of thermal contraction, so, just be difficult to film structural component 102 is expand into desirable curved surface as long as for example the film supporting member 103 of frame shape is made crooked shape.

Summary of the invention

The objective of the invention is to, a kind of manufacture method and structure that can not damage the structure of film supporting member or film structural component function and outward appearance when giving the heat treated of the essential tension force of film structural component is provided.In addition, the objective of the invention is to, a kind of manufacture method and the structure that film structural component can be made desirable curved structure is provided.

For achieving the above object, the 1st technical scheme of the present invention is the manufacture method of structure, this structure has film structural component and makes this film structural component form face ground all or part of film supporting member that keeps to its periphery, use elasticity raw material with heat-shrinkable as film structural component, under the no tension force or film structural component is fixed on the film supporting member with the also weak tension force of the tension force more required than structure, then, with the temperature maintenance of film supporting member at the low-temperature condition also lower than the melt temperature of this film supporting member, and film structural component heated, make the film structural component thermal contraction, give this film structural component tension force, make the necessary elastic force of structure performance.Therefore, can not make the fusion of film supporting member make the film structural component thermal contraction owing to being heated into, so can prevent to make when film structural component heated the phenomenon of the fusing of film supporting member, distortion, the performance that prevents structure is the situation of intensity or appearance damage for example.

Here, preferably utilize the heating that is configured in the position of leaving film structural component to carry out the heating of film structural component with thermal source.This occasion, film structural component do not contact heating and use thermal source, can prevent the film structural component fusing.Especially be the occasion of reticulate pattern at film structural component, can prevent that the reticulate pattern pattern from producing uneven situation.Therefore, can prevent for example situation of intensity or appearance damage of structure performance.

In addition, preferably, the heating of film structural component is undertaken by heating plate, and this heating plate leaves at least one face that film structural component is configured in film structural component, and have with thermal contraction after the parallel heating surface of described film structural component.In this occasion, heat by heating plate from the position of leaving film structural component, film structural component does not contact with heating plate, can prevent the film structural component fusing, when film structural component is reticulate pattern, can prevent that the reticulate pattern pattern from producing uneven phenomenon, the performance that can prevent structure is the situation of intensity or appearance damage for example.

In addition, also preferably, the heating of film structural component is undertaken by the heating plate that leaves the configuration of film supporting member.In this occasion, the heat of heating plate is difficult to be delivered on the film supporting member by formed space between heating plate and the film supporting member, can mainly only heat film structural component, the temperature of film supporting member can be heated to less than melt temperature and make film structural component produce thermal contraction.

In addition, preferably, along with the carrying out of the contraction distortion of film structural component and make heating plate carry out the heating of film structural component movably to film structural component.In this occasion, when avoiding heating plate and film structural component contacts, also can make the distance between them approaching as far as possible, and give the film structural component Necessary Tensility at short notice.

The heating plate that film structural component is heated preferably, its circumference is surrounded to the outstanding insulation part of film structural component.In this occasion, prevent that by insulation part the free convection heat from transmitting and radiation is conducted heat, prevent the heat transferred film supporting member of heating plate, can mainly heat, the temperature of film supporting member can be heated into less than melt temperature and make film structural component produce thermal contraction film structural component.In addition, flow to film supporting member side owing to suppressing the circumference of heat from heating plate, that is, owing to can reduce the thermal loss of heating plate, so can carry out the heating of film structural component effectively.Also have, can make the temperature of heating plate even, can carry out uniform heating film structural component.Have, insulation part plays the effect of dividing plate again, prevents that heating plate from contacting with film structural component.

In addition, film structural component and film supporting member, film structural component is configured under no tension force or with the also weak tension force of tension force more required than structure the film supporting member is carried out in the mould of injection molding, under the edge portion of film structural component is configured in state in the cavity that the film supporting member is formed, be shaped by the insertion that moldable resin is injected in the cavity, film structural component is fixed on the film supporting member.Therefore, owing to during the insertion shaping, film structural component is maintained in stretched condition, or when being installed in film structural component in the mould, needn't give the film structural component pretension, so the device of giving tension force needn't be set, manufacturing installation can be oversimplified.In addition,, can not expose,, can reduce the amount of the required film structural component of manufacturing structure so do not need from the film supporting member the pruning operation of film structural component cutting-out can be reduced flow chart because edge portion and the film supporting member of film structural component is integrated.In addition, because the edge portion and the film supporting member of film structural component are integrated, so can improve the outward appearance of structure.Here, shrink by the thermoplastic resin that forms the film supporting member, film structural component is easily lax, but eliminates by film structural component is heated that this is lax, can make film structural component have tension force.

In addition, the present invention is, will film structural component heated, and making it carry out thermal contraction by importing in the heating furnace after the structure that constituted by incorporate film structural component and film supporting member of being shaped promptly inserts the demoulding of shaping thing by inserting.Therefore, by in heating furnace film structural component being heated, available even temperature heating film member evenly shrinks film structural component, can give tension force equably.In addition, owing to indirectly film structural component is heated, in other words, the member after directly will not heating is by being pressed on the film structural component, so can prevent the film structural component fusing or produce uneven this phenomenon on the reticulate pattern pattern.And, by using large-scale heating furnace, also can disposable a plurality of structures be heated, can produce structure in a large number.

Compare with the melting point of the film structural component that is heated processing, the melting point of film supporting member also can be quite low, and the situation of the heat treated temperature that is lower than film structural component is also arranged.And, as the film supporting member, can use the melting point thermoplastic resin higher than the heat shrink temperature of film structural component, for example as the film supporting member, can use polyester, as film structural component, can use flexible polyester.In this occasion, owing to need not the film supporting member is maintained in the device that the low-temperature condition lower than melt temperature used, so even the heating furnace of packing into continuously of the structure after integrated carries out heat treated to film structural component with film structural component and film supporting member, the temperature of film supporting member is also less than melt temperature, fusing of film supporting member or distortion can be prevented, the heat treated operation can be carried out effectively.

In the manufacture method of structure of the present invention, structure has film structural component and makes this film structural component form face ground all or part of film supporting member that keeps to its periphery, as film structural component, use makes the structure after at least 2 kinds of different elasticity combination of raw materials of the thermal shrinking quantity under the same heating-up temperature, under the no tension force or film structural component is fixed on the film supporting member with the also weak tension force of the tension force more required than structure, then film structural component is heated, make film structural component produce thermal contraction, give this film structural component tension force, make the necessary elastic force of structure performance, simultaneously, utilize the difference of the thermal shrinking quantity of film structural component to make the tension force uneven distribution, the face of film structural component is formed the face of three-dimensional of for example curved surface of non-flat forms.Therefore, utilize the difference of the thermal shrinking quantity of film structural component, film structural component can be made required curve form.Thus, from ergonomics or attractive in appearance on problem etc., seat surface or backrest face etc. can be made excellent shape, in addition, can improve the free degree of design, and can improve the outward appearance and the performance of structure.

Here, film structural component also can make, and the thermal shrinking quantity of direction that should form straight line is bigger than the thermal shrinking quantity that should form direction of curve.In this occasion, the elasticity raw material that thermal shrinking quantity is big form straight line, are formed the raw-material restriction of elasticity of this straight line, and the elasticity raw material that thermal shrinking quantity is little form curve, its result, and film structural component just forms curved surface.

In addition, can provide the structure that utilizes above-mentioned manufacture method manufacturing, when giving the heat treated of necessary tension force, can not damage the function and the outward appearance of film supporting member or film structural component film structural component.And a kind of like this structure can be provided: its film structural component is excellent curved surface from ergonomics or this point that goes up attractive in appearance by extension.This structure for example can be used as general usefulness chair, office chair, operation chair, nurses with all chairs such as chairs, further be used as seat, backrest, supporting plate, headrest of vehicles such as bicycle, two-wheeled motorcycle, four-wheel automobile, bus etc., even be used as dividing plate or panel.

The specific embodiment

Below, the optimal morphology shown in describes structure of the present invention in detail with reference to the accompanying drawings.

Fig. 1 represents that the inventive method is applied to the 1st embodiment of the manufacturing of seats.For example, as shown in Figure 2, the structure 1 that constitutes this seats comprises film structural component 2 and makes this film structural component 2 formation faces ground part or all film supporting member 3 that keeps of periphery to film structural component 2, is used for being installed on the framework of chair the constituent part function at seat for example that plays chair on the foot frame for example etc.After tension force also weak under the no tension force or with the tension force more required than structure 1 is fixed on the film structural component 2 of this structure 1 on the film supporting member 3, only film structural component 2 is heated, the temperature maintenance of film supporting member 3 is become the low-temperature condition also lower than the melt temperature of this film supporting member 3, and film structural component 2 is heated into the degree that produces thermal contraction, make film structural component 2 thermal contractions, give this film structural component 2 tension force, make the necessary elastic force of structure 1 performance.

In the present embodiment, but film supporting member 3 makes the structure of the rigidity with the tension force that relies on self support membrane member 2.That is,, also has the rigidity that keeps profile as structure 1, so that film structural component 2 obtains Necessary Tensility even film supporting member 3 is not installed in other structures for example on the foot frame etc. of chair.Therefore, when being installed in structure 1 on the framework 4, needn't give film structural component 2 Necessary Tensility, so can carry out installation exercise easily.By the way, the shape of the film structural component 2 of present embodiment occasion and film supporting member 3 that its full periphery is kept makes the frame shape of the tabular and essentially rectangular of essentially rectangular, but is not particularly limited in this as the shape of structure 1.

In addition, in the present embodiment, film structural component 2 for example uses the reticulate pattern thin plate that fabric constituted of polyester line and elastic polyester line, for example the commodity reticulate pattern thin plate of wearing wild volt Lip river rib (ダイヤ Off ロ one ラ: Co., Ltd.'s system is spun by Japan) by name.But film structural component 2 is not limited to this example so long as to have elasticity raw material of heat-shrinkable just passable.By film structural component 2 is made reticulate pattern, can obtain high aeration and take the good comfortable structure 1 of mood.In addition, film supporting member 3 is the synthetic resin system of thermoplasticity.The thermoplastic resin that forms film supporting member 3 preferably adopts for example olefine kind resin of PET (PETG) or PP (polypropylene) etc.As described in present embodiment, by film supporting member 3 being made olefine kind resin system and film structural component 2 being made polyester, do not use screw etc. as if joint at them, but being separated, structure 1 do not recycle to former state use yet.The employed member in seat all utilizes plastics or elastomer to form, and does not use metal parts, needn't separately discard when discarded, can discard easily and recycling.But this situation is not the meaning that the material of film structural component 2 and film supporting member 3 is defined to the example of present embodiment.

In the present embodiment, by film supporting member 3 being carried out injection molding when being shaped these film structural components 2 and film supporting member 3, as pack into preformed film structural component 2 and of insert by integrated.But the fixing means of film structural component 2 and film supporting member 3 is not limited thereto.

Insert and be shaped for example shown in Figure 1A, by film supporting member 3 and film structural component 2 being inserted in the patrix 7 of shaping usefulness and the mould 5 that counterdie 8 is constituted, the film structural component 2 that will have a heat-shrinkable is mounted to no tension force or is applied with than structure 1 required tension force also behind the state of weak tension force, with the mould closure, by in cavity 6, penetrating thermoplastic resin and making its curing, film supporting member 3 is formed.Then as required, the insertion drip molding that will take out from mould is after structure 1 is installed on the supporting base 60, shown in Figure 1B, to carry out heat treated, makes film structural component 2 thermal contractions, gives tension force, the elastic force of necessity of performance structure 1.

Here, in the cavity 6 of the counterdie 8 of present embodiment, be provided with the core pin 10 that on the film supporting member 3 of structure 1, forms through hole 9 usefulness of above-below direction.When being installed in film structural component 2 on the mould 5, the edge portion of film structural component 2 carries out temporary fixed location after being injected by each core pin 10.Therefore,, also periphery correctly can be located, to be incorporated in the cavity 6 even film structural component 2 is not supported from the outside of mould 5.In addition, because the device that needn't support film structural component 2 in the outer setting of mould 5, so manufacturing installation is oversimplified.And, since the edge portion of film structural component 2 do not expose in the cavity 6 integrated with film supporting member 3, so the deburring operation that needn't prune film structural component 2 from the film supporting member 3 can reduce flow chart, can reduce the amount of structure 1 being made necessary film structural component 2.In addition, because the periphery 11 of film structural component 2 is integrated with film supporting member 3, so can improve the outward appearance of structure 1.

Here, because film structural component 2 is reticulate pattern thin plates, thus resin is spread when integrated film structural component 2 by the injection molding of film supporting member 3, between the line of woven fabric and line, to pass through resin and coverlay member 2.Thus, preformed film structural component 2 is integrated fixing with the film supporting member 3 that forms by injection molding.

And the thermoplastic resin in will injecting to cavity 6 by the action of not shown outstanding device, after will taking out from mould 5 as the drip molding of structure 1, shown in Figure 1B, is placed on the supporting base 60 of heat treatment apparatus after solidifying.Heat treated is performed such: become the temperature maintenance of film supporting member 3 than the also low low-temperature condition of the melt temperature of this film supporting member 3 and be heated to the degree that makes film structural component 2 generation thermal contractions.At this moment, when film supporting member 3 is carried out injection molding, because the part by patrix 7 and counterdie 8 clampings of film structural component 2 is not heated to the degree of shrinking that produces, so produce lax to a certain degree.And, produce when solidifying and shrink, so film structural component 2 is lax bigger owing to film supporting member 3.Can eliminate this by the contraction that heating is produced and relax, and give the tension force of regulation.

Device 53 to the used film structural component 2 of heat treated heats uses the metal heating plate that for example heats by electric heater in the present embodiment.But heater 53 is not limited to the example of this electric heater.For example, also can use, also can be directly the heat of electric heater be applied on the film structural component 2 by heating plate with the heater as heating source such as hot blast, steam, light.

Do not give film supporting member 3 for making heat, heating plate 53 forms than the formed interior less similar shape of contour shape of the interior sidewall surface of film supporting member 3, for example form four angles and be circular rectangle, and have and the heating surface of film structural component 2 almost parallels of tensioning by thermal contraction in the occasion of present embodiment.At this moment, can be with film structural component 2 whole evenly heating.But the shape of heating plate 53 is not limited thereto.In addition, the heater 54 that heating plate 53 is heated usefulness preferably is arranged to make the uniformity of temperature profile in the heating plate 53.For example, as shown in Figure 3, a plurality of heaters 54 uniformly-spaced are configured on the heating plate 53.Thus, the Temperature Distribution in the heating plate 53 just evenly, just can heat film structural component 2 integral body equably.In addition, in the present embodiment, shown in Figure 1B, dispose heating plate 53 in the face side of film structural component 2 and the two sides of rear side.At this moment, can heat simultaneously from table, the back of the body two sides of film structural component 2, the surface and the back side are shunk, therefore can not produce distortion or warpage, and film structural component 2 is shunk, give Necessary Tensility, make and handle rapidization, be preferable.In addition, can make the thermal shrinking quantity of the face side of film structural component 2 and rear side even, can give film structural component 2 uniform tension force.But the configuration of heating plate 53 not necessarily is limited to the example of present embodiment.For example, also can be only dispose heating plate 53 the table of film structural component 2, either party in the back side.In addition, also can be only the table of film structural component 2, in the back side either party's side configuration heating plate 53, the configuration of the opposing party's side for example the metallic plate after mirror finish etc. as heat reflection plate, heat by 53 pairs of film structural components 2 of heating plate from this side side, utilize the heat after heat reflection plate reflects that film structural component 2 is heated from this opposing party's side.

Here, as the temperature maintenance in the film supporting member 3 being become, for example can enumerate following example than also low low-temperature condition of the melt temperature of this film supporting member 3 and the measure that film structural component 2 is heated.As the 1st measure is shown in Figure 1B, adopts the heating plate 53 of the similar shape littler than the interior contour shape of film supporting member 3, and is provided with space L1 between heating plate 53 and film supporting member 3.At this moment, because space L1, the heat of heating plate 53 is difficult to be delivered to film supporting member 3, can mainly heat film structural component 2, can prevent the phenomenon of film supporting member 3 fusings.As the 2nd measure is shown in Figure 1B, and the thermal insulation board of giving prominence to film structural component 2 from the circumference of heating plate 53 55 as insulation part is set.At this moment, utilize thermal insulation board 55 to prevent that the heat of heating plate 53 is delivered on the film supporting member 3 by free convection heat transfer, can mainly heat, can prevent 3 fusings of film supporting member film structural component 2.In addition, since can suppress heat from the edge portion of heating plate 53 to film supporting member 3 side flow, so when film structural component 2 is heated, can reduce thermal loss effectively.Also have and since thermal insulation board 55 prevent from around the entering of cold air, so can make the temperature of heating plate 53 of thermal insulation board 55 inboard on every side even, can heat film structural component 2 equably.Have, thermal insulation board 55 plays spacer function again, prevents that heating plate 53 from contacting with film structural component 2.And, preferably use for example little thermal insulation material of pyroconductivity such as pottery, but be not limited to this material for thermal insulation board 55.In addition, in the present embodiment,, thermal insulation board 55 is set and between thermal insulation board 55 and film supporting member 3, sets space L1 for preventing the heat transferred film supporting member 3 of heating plate 53 more reliably, but according to circumstances, but the structure of also only a certain side being implemented.

As the temperature maintenance in the film supporting member 3 being become, be not limited to above-mentioned example than also low low-temperature condition of the melt temperature of this film supporting member 3 and the method that film structural component 2 is heated.For example, also can use the anchor clamps that film supporting member 3 is covered that constitute by thermal insulation materials such as potteries, and under this state, film structural component 2 be heated.For example, thermal insulation anchor clamps 56 as shown in Figure 4 are formed the frame shape corresponding with film supporting member 3, and can be divided into upper member 56a and lower side member 56b.By sandwiching film supporting member 3 with upper member 56a and lower side member 56b, film supporting member 3 is covered, only the film structural component 2 of film supporting member 3 inboards of frame shape exposes.At this moment, even the heating-up temperature of film structural component 2 is higher than the melt temperature of film supporting member 3, also can utilize thermal insulation anchor clamps 56 to prevent that film supporting member 3 is heated, so even heater 53 is not implemented special measure, also can only heat, can prevent 3 fusings of film supporting member film structural component 2.The cooling device of the temperature decline that makes film supporting member 3 also can be set in addition.As shown in Figure 5, also can use the heater 58 that is provided with heater 54 in the position relative and around film supporting member 3, has cooling device 57, film structural component 2 is heated with film structural component 2.Cooling device 57 is the cooling water channels that for example make flow of cooling water.At this moment, utilize cooling device 57 that film supporting member 3 temperature is on every side descended, the temperature maintenance in the film supporting member 3 is become the low-temperature condition also lower than the melt temperature of this film supporting member 3, and film structural component 2 is heated.

In addition,, when using the device that hot blast, steam and light etc. take place, also can not contact as shown in Figure 6, and be that object blows out hot blast or steam only with film structural component 2 with film supporting member 3 as heater 53, or irradiates light.At this moment, shown in the dotted line of Fig. 6, hot blast, steam and light etc. not with scope that film supporting member 3 contacts in, heater 53 is moved.Certainly, in the occasion of using thermal insulation anchor clamps 56 shown in Figure 4, this measure does not just need.In addition, when film structural component 2 is heated, also can blow a cold wind over to film supporting member 3.

Here, preferably film structural component 2 is heated from the position of leaving film structural component 2.At this moment, can prevent that film structural component 2 from contacting with heating plate 53 and produce fusing or the reticulate pattern pattern of film structural component 2 produces uneven phenomenon, can prevent the function of structure or the situation of appearance damage.For example in the present embodiment, becoming and film structural component 2 non-contacting position configuration heating plates 53.But the anxiety of no performance decline and can't see from the outside under the situation of film structural component 2 on as the intensity of the structure of chair when the skin members of coverlay member 2 for example is installed, also can make heating plate 53 contact with film structural component 2 on rear side of film structural component 2 etc.For example, be configured in the downside heating plate 53b of rear side of film structural component 2 also configurable with film structural component 2 position contacting roughly, in other words, also configurable film structural component 2 not being pushed with film structural component 2 position contacting.

In addition, heater 53 preferably movably, to follow the contraction distortion of film structural component 2.At this moment, make heater 53 short as far as possible, can give film structural component 2 Necessary Tensility at short notice with the distance of film structural component 2.For example, in the present embodiment, the retractile cylinder assembly 59 of use in order to extend near film structural component 2, to shrink in order to leave film structural component 2, with the lax outstanding side of film structural component 2, the present embodiment occasion is that the upside heating plate 53a that is configured in film structural component 2 face side is supported to liftable.Certainly, in such occasion that relaxes to film structural component 2 back sides (interior) side, also available cylinder device 59 makes downside heating plate 53a lifting.Shown in Figure 1B, in the lax heating starting stage of film structural component, this cylinder assembly 59 does not contact with film structural component 2 and in the position of leaving film structural component 2 heating plate 53 is supported, the lax elimination that makes film structural component 2 along with heating, shown in Fig. 1 C, cylinder assembly 59 elongations are so that heating plate 53 is near film structural component 2.The mobile control of heating plate 53, i.e. also any of automatic or manual of the extension and contraction control of cylinder assembly 59.When controlling automatically, try to achieve for example dependency relation of heat time heating time and film structural component 2 distortion in advance, also can be according to heating plate 53 is moved, perhaps, also can set in advance the sensor that the distance to film structural component 2 and heating plate 53 detects, according to this signal of sensor, heating plate 53 is moved, make film structural component 2 and heating plate 53 keep certain distance.In addition, heating plate 53 to move also interim be interrupted or continuous any form.For example in the present embodiment, upside heating plate 53a is moved, so that the heating surface of face that film structural component 2 forms after thermal contraction and upside heating plate 53a is 40mm → 30mm → 15mm apart from phasic Chang.And in the example of Figure 1B,, downside heating plate 53b is moved though upside heating plate 53a is moved, upside heating plate 53a and downside heating plate 53b both sides are moved.Though being arranged to heater 53 removable is preferable example, is not limited to this structure.

Here, as film structural component 2, the occasion of the present embodiment of the reticulate pattern thin plate that constitutes at the fabric that adopts by polyester line and elastic polyester line, temperature when film structural component 2 is heated and heat time heating time be the scope below for example preferably.Heating plate 53 when roughly contacting configuration with film structural component 2, the temperature of for example downside heating plate 53b preferably make for example scope about 120～250 ℃, and the scope that makes about 180～190 ℃ is better.Heating plate 53 when being configured to film structural component 2 noncontacts, for example the temperature of upside heating plate 53a preferably makes for example scope about 180～300 ℃, and the scope that makes about 190～240 ℃ is better.Preferably make heat time heating time for example about 40～120 seconds.The temperature that adds the film supporting member of pining for 3 of film structural component 2 is normal temperature or near the temperature of normal temperature preferably, and the temperature difference that this adds the film structural component 2 pined for and film supporting member 3 is better more than 150 ℃ preferably about 5～200 ℃.But best heating condition is transformable according to the raw material of selecteed film structural component 2 etc., may not be defined in above-mentioned condition.

As mentioned above,, then shown in Fig. 1 C, film structural component 2 is shunk, make structure 1 have necessary elastic force by film structural component 2 is heated.Here, in the time of on the film structural component 2 after will bigger load acting on firm heating,, therefore,, preferably film structural component 2 is dispelled the heat or cool off in order not act on this load because film structural component 2 is easy to generate distortion.For example, in the present embodiment, give the film supporting member 3 Necessary Tensility, then, structure 1 is installed in other structure for example places a period of time slightly on the framework 4, carry out the nature cooling by heating.At this moment, the distortion of film supporting member 3 in the time of can preventing thermal contraction.Structure 1 is installed in that to be not limited to screw on the framework 4 fastening, for example will block claw stop and film supporting member 3 is integrally formed, also its disposable operatively card can be ended at the support of framework 4 or supporting member side for example in hole or the recess.

Below, another embodiment of the present invention of key diagram 7A～7C.Among Shuo Ming another embodiment,, put on identical symbol below, omit detailed explanation for structural element same as the previously described embodiments.

The manufacture method of this structure is, at first, under no tension force or with the tension force also more weak, film structural component 2 is pre-configured in film supporting member 3 is carried out in the mould 5 of injection molding than structure 1 necessary tension force, under the state in the edge portion with film structural component 2 is configured in the cavity 6 that film supporting member 3 is formed, be shaped by the insertion that thermoplastic resin is injected in the cavity 6, and be configured as a kind of like this state: under no tension force or with the tension force also more weak, film structural component 2 is fixed on the film supporting member 3 than structure 1 necessary tension force.Then, the uncompleted structure of the insertion drip molding that will take out from mould 5 is introduced in the heating furnace 61, utilize furnace inner environment that the temperature maintenance of film supporting member 3 is become the low-temperature condition also lower than the melt temperature of film supporting member 3, and with film structural component 2 heating, make film structural component 2 produce thermal contraction, give this film structural component 2 tension force, the elastic force of necessity of performance structure 1.

Here, as the temperature maintenance of film supporting member 3 being become be than also low low-temperature condition of the melt temperature of film supporting member 3 and the measure of heating, in the melt temperature of film supporting member 3 the low occasion of the necessary temperature of heat treated (thermal contraction) than film structural component 2, by using the thermal insulation anchor clamps 56 of Fig. 4, and when for example the polyester resin of PET (PETG) etc. was used for film supporting member 3 at the resin of the high temperature that melt temperature is higher than the temperature that film structural component 2 is shunk, it was lower than the melt temperature of film supporting member 3 to set temperature for, realize than the high furnace inner environment temperature of temperature that film structural component 2 is shunk.At this moment, even film structural component 2 and film supporting member 3 are heated in the incorporate structure 1 introducing heating furnace 6, also can prevent the situation of 3 fusings of film supporting member or distortion.Film structural component 2 also can use for example identical with the above embodiments member.But film structural component 2 and film supporting member 3 not necessarily are defined in these materials, also can use the melting point of film supporting member 3 to produce the combination of the temperature of contraction as the other materials of higher temperature than film structural component 2.But, as shown in Figure 4, when using the anchor clamps 56 coverlay supporting members 3 that constitute by thermal insulation materials such as potteries, will melting point not be used for film supporting member 3 for material than the temperature higher temperature that film structural component 2 is shunk.Temperature in the heating furnace 61 when film structural component 2 is heated is the scope about 120～250 ℃ for example preferably, is more preferably the scope about 180～190 ℃.In addition, heat time heating time the scope about 40～120 seconds for example preferably.With film structural component 2 and film supporting member 3 incorporate methods, for example the 1st embodiment with above-mentioned is identical owing to can make with film supporting member 3 injection moldings the time, omits so describe in detail.

Here, heating furnace 61 preferably uses the far infrared line oven.At this moment, far infrared has the inside that is heated to the resin material that constitutes film structural component 2, the advantage that makes film structural component 2 evenly shrink and can give uniform tension.But so long as heating furnace 61 can be heated to the temperature that can give film structural component 2 Necessary Tensility, its kind does not limit this example.

Film structural component 2 and film supporting member 3 are that integrally formed structure 1 is placed in the heating furnace 61 and heats.The supporting base that when symbol 62 is film structural component 2 heating film supporting member 3 is supported.By using heating furnace 61, can heat film structural component 2 with even temperature.Therefore, film structural component 2 is evenly shunk, give uniform tension force.In addition, owing to give film structural component 2 indirectly with heat, in other words, the member after directly will not heating presses against on the film structural component 2, produces uneven phenomenon so can prevent film structural component 2 fusings or reticulate pattern pattern.In addition,, also can heat a plurality of structures 1 once, can produce structure 1 in a large number by using large-scale heating furnace 61.For example, also a plurality of structures 1 can be put on the hear resistance belt conveyor, make the continuous processing stove that in heating furnace 61, moves successively.

Mainly the present invention the 3rd embodiment is described below with Fig. 8.The manufacture method of this structure is, as film structural component 2, use makes the structure after at least 2 kinds of different elasticity combination of raw materials of the thermal shrinking quantity under the same heating-up temperature, when making film structural component 2 produce thermal contraction by heat treated and give the elastic force of these film structural component 2 tension force, performance structure necessity, utilize the difference of the thermal shrinking quantity of film structural component 2 to form three-dimensional face.

The film supporting member 3 of present embodiment makes 3D shape arbitrarily, the frame shape of the essentially rectangular after for example being bent downwardly as front portion as shown in Figure 8, the seat.And, film structural component 2 is the ordinate 63 that will uphold to the fore-and-aft direction of seat surface (being also referred to as vertically) and the reticulate pattern thin plate that forms with horizontal line 64 braidings that the direction to the left and right (being also referred to as laterally) of these ordinate 63 quadratures is upheld, and the thermal shrinking quantity that adopts horizontal line 64 is bigger and can obtain structure than high tension than ordinate 63.For example in the present embodiment, it is the polyester line of 300 Denier that ordinate 63 uses thickness, and it is the elastic polyester line of 1850 Denier that horizontal line 64 uses thickness.Therefore, in the bend 65 of film supporting member 3, horizontal line 64 connects 65,65 straight lines of this bend, and ordinate 63 is subjected to horizontal line 64 restrictions and forms the curve corresponding with the bend 65 of film supporting member 3 by horizontal line 64.Its result, the bend 65 of film structural component 2 and film supporting member 3 is corresponding and form curved surface.

Like this, carry out various changes by at least 2 kinds of raw-material combined methods of elasticity that the thermal shrinking quantity under the same heating condition is different etc., the face of the structure that thereby film structural component 2 can be constituted makes 3D shape arbitrarily, in the occasion that is used for chair structure etc., its design freedom can be improved, and outward appearance and performance can be improved.For example preferably the shrinkage factor ((length after original length-contraction)/original length * 100) of the ordinate 63 of this occasion is made about 3.3～6.6%, the shrinkage factor of horizontal line 64 is for example made about 8.5～9.0%.But the desired shrinkage factor of raw material is that the desired elastic force of face that can form according to chair shape and film structural component 2 etc. changes, and not necessarily is defined in above-mentioned example.In addition, with film structural component 2 be installed in method on the film supporting member 3 and measure, method that film structural component 2 is heated and measure etc., preferably make identically with the 1st or the 2nd embodiment, but may not be defined in these examples.

But the structure that forms the film structural component 2 that required curved surface uses not necessarily is limited to above-mentioned example.

For example, making the raw material of ordinate and horizontal line inequality also is a preferred embodiment.For example, shown in Fig. 9 A and Fig. 9 B, except the side with in-line direction and crossline direction makes elastica 66, the opposing party is made the polyester line 67, but it is also such shown in image pattern 10A and Figure 10 B, one side of ordinate and horizontal line is made the structure of alternate configurations elastica 66 and polyester line 67, the opposing party is made elastica 66 or polyester line 67.Perhaps, using the pliability of ordinate and horizontal line is the different elastica of coefficient of elasticity.And as elastica, can use the elastic polyester line, Pei Lupulai (registration mark of Co., Ltd. is spun by Japan) or breathe out her rabbit Lay (registration mark of Dong Li E.I.Du Pont Company, Japanese: the eastern レデュ Port Application login merchant Standard of society) etc. for example.

In addition, even the line that is made of same raw materials also can make the amount of contraction difference by manufacture method.For example, because the amount of contraction of elastica has the upper limit, so in the knitting process of fabrication stage of film structural component 2, add man-hour, in case improve the temperature when making elastica melt together, then because the contraction quantitative change of the elastica of this moment is big, so the elastica amount of contraction that the tension force to film structural component 2 that carries out after being installed in film structural component 2 on the film supporting member 3 is given in the operation diminishes.For example, by 190 ℃ of film structural components of making 2, the amount of contraction ratio of giving the elastica in the operation at tension force is little by 170 ℃ of film structural components of making 2.If utilize above-mentioned character, the temperature when then making by adjusting film structural component 2 can be adjusted into required amount of contraction with the amount of contraction of the tension force of film structural component 2 being given the elastica in the operation.In addition, polyester line for example, because the colouring method of temperature that its amount of contraction also heats line because of when dyeing and the number of times that heats etc. is different, so, the amount of contraction of the tension force of film structural component 2 being given the polyester line in the operation can be adjusted into required amount of contraction by selecting this colouring method.In addition, by the cross sectional shape of the line that constitutes film structural component 2 or the thickness of line etc. are suitably selected, also the amount of contraction of the tension force of film structural component 2 being given this elastica in the operation can be adjusted into required amount of contraction.

In addition, for example shown in image pattern 11A～Figure 11 B like that, make the density of the ordinate 63 that constitutes film structural component 2 and horizontal line 64 radical of promptly throwing a spear inequality, also can make the amount of contraction of film structural component 2, tension force inequality at vertical and horizontal.In addition, said method also capable of being combined uses.As film structural component 2, also can use at different film of vertical and horizontal thermal shrinking quantity etc.And, also can make the thermal shrinking quantity of a part in the film structural component 2 and other parts inequality.

The foregoing description is an example of preferred embodiment of the present invention, but is not limited thereto, and without departing from the spirit and scope of the present invention, can do various distortion.For example, the shape of film structural component 2 and film supporting member 3 is not limited to the example of present embodiment.For example, also film structural component 2 can be made tubular or bag shape, film supporting member 3 is encased as shown in Figure 13.In addition, film supporting member 3 not necessarily limits the ring-type that forms sealing so long as the face that film structural component 2 can be formed as the shape of purpose gets final product, and can be the structure of semicircular or U font, L font, in addition, also can be not shown from 2 outstanding bars of framework.Film supporting member 3 is again to all or part of structure that keeps of periphery of film structural component 2, preferably to 2 relative at least structures that the limit keeps of the periphery of film structural component 2.Here, described 2 relative limits are unnecessary to be parallel relation, but comprises polygonal 2 the crossing limits such as triangle or the part of nonparallel 2 limits or circular even oval-shaped relative position relation etc., can make film structural component 2 produce all shapes and the position relation of tension force.For example shown in the image pattern 12,13 like that, the roughly H shape after 51 connections of retaining member that film supporting member 3 also will keep the 1 relative oppose side edge portion of film structural component 2 with connecting elements 52.In the film supporting member 3 of this shape and the occasion of film structural component 2 combinations, the also side configuration heating plate or other the heater that are kept of tunicle supporting member 3 never.And be the occasion of bag shape at film structural component 2 as shown in Figure 12, also can on film structural component 2, set in advance the hole of the fastening usefulness of screw, perhaps also can make the bolt of the fastening usefulness of screw connect the film structural component 2 relative with retaining member 51 or connecting elements 52.In addition, in the example shown in Fig. 1 and Fig. 2 etc.,, be not limited thereto, for example can make circular or tubular shape, or make shapes as required such as polygon or L shaped shape though the cross sectional shape of film supporting member 3 is rectangles.These shapes can be set according to installation or the design etc. of chair on framework.

In addition, as film structural component 2, the also membranoid substance that has heat-shrinkable and have necessary elasticity and intensity, for example also reticulate pattern thin plate of nylon system as structure 1.But being not limited to the reticulate pattern thin plate, also can be other materials such as film or ethene or cloth, nonwoven etc.As film, for example can use the film of polyvinyl chloride system.

In the 1st embodiment, utilize the thermoplastic resin film supporting member 3 that has been shaped, but be not limited thereto, also can use the thermosetting resin that hardens with the temperature that is lower than film structural component 2.At this moment, film supporting member 3 is heated to the degree of sclerosis, and film structural component 2 and film supporting member 3 is integrated, can heats film structural component 2 then and make its contraction.In addition, the thermoplastic resin that forms film supporting member 3 is not limited to olefine kind resin, for example, can use the general like that known or novel material as film supporting member 3 of polyester.And any all available polyester constitutes in film supporting member 3 and the film structural component 2.Also can carry out recycling with structure 1 former state ground this moment.

In addition, as reticulate pattern formula panel, also can be used for the backrest of automobile etc.Structure 1 of the present invention is dividing plate also.Be the occasion etc. of dividing plate at structure 1, film supporting member 3 also can make and will disperse to be configured in structure on the periphery of film structural component 2 than the maintaining part of short wire of the periphery of film structural component 2 or point-like, utilizes these a plurality of maintaining parts that film structural component 2 is supported.

In addition, as purposes of the present invention, yes general with chair, office chair, operation with chair, nursing all chairs with chair etc., the seat, backrest, supporting plate, headrest etc. that are applied to vehicles such as bicycle, two-wheeled motorcycle, four-wheel automobile, bus are effective.

Yet though structure 1 directly can be used as the seat of chair or backrest etc., according to occasion, skin members also can be mounted to the state that the integral body with the upper surface of film structural component 2 and film supporting member 3 and lateral surface covers.Thus, the peripheral part of exposing the film structural component 2 on film supporting member 3 upper surfaces can be covered, outward appearance can be made design and color arbitrarily.In addition, this occasion between skin members and film supporting member 3, also can for example clamp the foamed resin of polyurethanes etc. or fibrous padded coaming etc.Thus, can prevent that the film supporting member 3 of hard from directly running into the health of seated person, prevent to cause pain or sticky feeling, use mood good to seated person.

In addition, when being installed in this structure 1 on the chair,, also can being provided with the film supporting member 3 of structure 1 and the integrated part of film structural component 2 are covered hiding cover member 13 for example as Figure 14, Figure 17 and shown in Figure 21.At this moment, hide owing to can utilize cover member 13 that integrated part is covered, thus can make outward appearance good, and the joint of film structural component 2 and film supporting member 3 is strengthened.Though cover member 13 makes olefine kind resin system or polyester member, preferably structure 1 integral body is made former state ground and carry out recycling.In addition,, can prevent that the member of hard from directly running into the health of seated person, prevent to cause pain or sticky feeling, use mood good to seated person by cover member 13 being made for example flexible resinous member.On the other hand, if cover member 13 is made for example high resinous member of hardness, then can improve the intensity of structure 1.

Here, the installation of cover member 13 on film supporting member 3 is that for example the insertion forming mode by the order shown in Figure 15 A～15C carries out.At this moment, as shown in figure 14, be preferably in the protruded stigma 14 of the through hole 9 of integrally formed telescope structure thing 1 on the cover member 13, the bolt 15 that utilize to connect is with the framework 4 of chair or supporting member fixed thereon and screw is fastened on this protruded stigma 14.In this occasion, can be provided at the seat that does not expose bolt etc. in appearance.

That is, shown in Figure 15 A, will make film structural component 2 film supporting member 3 and integrally formed of film structural component 2 before shrinking be installed in cover member 13 is carried out in the cavity of mould 16 of injection molding by heat treated with the core pin 17 of location usefulness.And, shown in Figure 15 B, penetrate the thermoplastic resin that is called PET or PP.When after thermoplastic resin solidifies, it being taken out, can obtain cover member 13 and film supporting member 3 incorporate structures 1.Then, film structural component 2 is implemented heat treated, film structural component 2 is shunk, give structure 1 Necessary Tensility.So, because cover member 13 and film structural component 2 are fixed on the sectoral integration on the film supporting member 3, so can strengthen the confining force of film structural component 2.In the present example,, be not limited thereto though before carrying out heat treated, cover member 13 is installed on the film structural component 2, also can be after film structural component 2 be carried out heat treated, cover member 13 makes integrated on the cover.

In that cover member 13 is inserted the occasion that is shaped, shown in Figure 16 A～16C, the position of the cast gate 19 when preferably making the position of the cast gate 18 when film supporting member 3 carried out injection molding and cover member 13 being carried out injection molding is inequality.For example, 2 place's cast gates 18 are set, and separate 180 degree 2 place's cast gates 19 are set, then because the position 20,21 of the weld mark that produces can not overlap each injection molding the time, so can strengthen the intensity of structure 1 with their 90 ° of ground that stagger if separate 180 degree.Specifically, if for example leave more than the 10mm, then the rigidity of structure 1 is unaffected basically, in fact no problem between the weld mark 20,21.

In addition, cover member 13 is the standing part of coverlay member 2 and film supporting member 3 at least also, but according to occasion, also can be as shown in Figure 17 with from the upper surface of film supporting member 3 to whole covering of lateral surface and by integrated.This occasion, to become cross section be the frame shape thing of rectangle because 13 liang of available film supporting member 3 and cover members be square, thus can be with the stationary plane of film supporting member 3 and film structural component 2 hiding and make outward appearance good, in addition, because structure 1 outward appearance looks that to look like a member the same, so can make outward appearance good.

In addition, when for example the lower surface of film supporting member 3 and medial surface exposes and film structural component 2 between stationary plane the time, also can be provided with from the inboard and this stationary plane partly to be covered hiding cover member 13.In this occasion, owing to also can utilize cover member 13 that the integrated part covering of film supporting member 3 and film structural component 2 is hidden, so can make outward appearance good.

In addition, the part that the mould 16 that film supporting member 3 is carried out the mould 5 of injection molding and cover member 13 is carried out injection molding also can shared mould.For example, shown in Figure 18 A～Figure 19 C, when shared counterdie 8, at first shown in Figure 18 A, after the lax tension force of core pin 10 usefulness of utilizing counterdie 8 is installed film structural component 2, with patrix 7 closures, from cast gate 18 thermoplastic resin is injected in the cavity, form film supporting member 3.And, after film supporting member 3 solidifies, take off patrix 7, under with integrally formed the state of still staying on the counterdie 8 of film supporting member 3 and film structural component 2 (Figure 18 C), closing forms the patrix 16 (with reference to Figure 19 A) of cover member 13 usefulness.And shown in Figure 19 B, the cast gate 19 that forms usefulness from the cover member penetrates thermoplastic resin formation cover member 13.After cover member 13 solidifies, shown in Figure 19 C, take out structure 1, film structural component 2 is implemented heat treated, obtain Necessary Tensility.

In addition, shown in Figure 20 A～Figure 20 B, also can use mould 7 with slide block 41, and this slide block 41 can and injection molding spare between form the cavity of shaping cover member 13.At this moment, when to film supporting member 3 injection moldings, shown in Figure 20 A, resin is injected to slide block 41 be fixed in the mould on the inboard closing position formed film supporting member 3.Then, slide block 41 is slided, and be fixed on the open position in the outside, resin is injected in the space between film supporting member 3 and the slide block 41, cover member 13 is shaped as Figure 20 B.In addition, the material as cover member 13 also can adopt thermosetting resin, being shaped by compression molding or multistation forms cover member 13.Adopt this mould 7, as long as slide block 41 is slided, integrally formed that just can form film supporting member 3 and film structural component 2 and cover member 13 as structure 1, so can reduce the labour of die cost and forming operation.

In addition, as shown in figure 21, also can be with the cover member of making by injection molding in advance etc. 13, be fixed into by welding or mode such as bonding stationary plane film supporting member 3 and film structural component 2 is covered.This occasion with compare with integrally formed incorporate situation of film supporting member 3 and film structural component 2 by injection molding, can be inexpensively that cover member 13 is integrated.Bonding cover member 13 employed bonding agents are olefine kind resin system or polyester, preferably structure 1 whole former state ground can be carried out recycling.

In addition, ground integrated by film structural component 2 is embedded in the film supporting member 3 fully, thus also can not need cover member 13.Owing to the integrated part of film supporting member 3 and film structural component 2 can be hidden, so can improve outward appearance.In the occasion that film structural component 2 is embedded in fully in the film supporting member 3, as shown in figure 22, for example, film structural component 2 was pushed and left cavity 6 from table back of the body both sides table is set on each

mould

7,8, and to carry on the back the supporting member that two profiles support be core pin 23,24.In this occasion, owing to being the profile support membrane member 2 that core pin 23,24 leaves cavity 6, so can not expose table back of the body two sides at film supporting member 3 by supporting member.Here, preferably form chimeric protuberance 23a and recess 24a mutually at the front end of each core pin 23,24.Like this, when film structural component 2 being clamped and during 23,24 butt joints of each core pin, protuberance 23a connects film structural component 2 and can be fixed, therefore, the dislocation of film structural component 2 in the time of can suppressing thermoplastic resin and penetrated.

In addition, it is also integrated film structural component 2 to be exposed in the lower face side of film supporting member 3.In this occasion, for example image pattern 23 is such, film supporting member 3 is placed on the framework 4 of chair, by the integrated part of film structural component 2 and film supporting member 3 is pushed, just can strengthen the fixing of film structural component 2.

In addition, as Figure 24 or shown in Figure 25, also can make film structural component 2 and carry out face with respect to the cavity face of cast gate 18 and install contiguously.In this occasion, owing to also pushing the thermoplastic resin 27 that penetrates from cast gate 18 is pressed against on the face with cast gate 18 relative sides, so the dislocation of film structural component 2 can prevent to insert shaping the time to film structural component 2.Here,, be not limited to this though film structural component 2 contacts with 5 on mould, even line contact or some contact, also can be by film structural component 2 is pressed against on the mould 5, the dislocation the when insertion that suppresses film structural component 2 is shaped.

As Figure 26～shown in Figure 28, also can film structural component 2 and the profile that is provided with cavity 6 ingates 18 are contacted as face install in, in the position relative with the cast gate 18 of film structural component 2, formation can be by the portion that dodges 26 of resin.Here,, as shown in figure 26, can make, perhaps also can make the hole shape of representing with double dot dash line like that as shown in figure 29 from the shape of the edge portion incision of film structural component 2 as the shape of dodging portion 26.In this occasion, because can be by the portion that dodges 26 of film structural component 2 easily around going into, so film structural component 2 can be pressed against on the face of cast gate 18 sides from dorsal part to the dorsal part of film structural component 2 from the thermoplastic resin 27 of cast gate 18 ejaculations.And thermoplastic resin 27 can not be subjected to film structural component 2 and can spread all over equably in the cavity 6 with hindering.Figure 27 is illustrated on the patrix 7 situation that configuration cast gate 18 and film structural component 2 faces are installed in profile on the cavity 6 contiguously, and Figure 28 is illustrated in the situation that configuration cast gate 18 on the counterdie 7 and film structural component 2 faces are installed in 6 times profiles of cavity contiguously.

In addition, as shown in figure 22,, also can use at position and form the film structural component 2 of dodging portion 26 with respect to mould gate for the structure 1 that film structural component 2 is embedded in fully in the film supporting member 3.At this moment, the thermoplastic resin that penetrates from cast gate can easily around going into to the dorsal part of film structural component 2, therefore, can spread all over thermoplastic resin in the cavity 6 equably by the portion that dodges 26 of film structural component 2.At this moment, as shown in figure 29, be preferably in the portion of dodging 26 near opening 40 is set.Like this, thermoplastic resin can easily spread all over the table dorsal part of film structural component 2 by dodging portion 26 and opening 40.

In addition, the supporting of the film structural component 2 in the mould also can be, core pin 10 is not set and is to form locking protrusion on the cavity face in the profile of mould 5, and film structural component 2 hooks are installed on the mould 5 thereon.At this moment, if be necessary on structure 1, to be provided with through hole 9, then also can behind injection molding, carry out hole processing.Perhaps, on 6 of cavitys, locking protrusion is not set, and film structural component 2 is placed on the counterdie 8.Under these occasions, owing to also the periphery of film structural component 2 can be housed in the cavity 6, so can omit the device that film structural component 2 supported by the outside of mould 5 and manufacturing installation is oversimplified, do not need to carry out the deburring operation and just can improve operation and outward appearance, also can reduce the amount of making structure 1 a needed film structural component 2.

And for example shown in Figure 30, pushing member 28 also can be set on mould 8, film structural component 2 pushings are fixed on the cavity face.Here, pushing member 28 double as core pins.This pushing member 28 does not insert film structural component 2 ground and only film structural component 2 is pressed against on the profile of cavity 6.At this moment, can prevent that film structural component 2 is because of the movable phenomenon of the ejaculation of thermoplastic resin 27 when film supporting member 3 carries out injection molding.

In addition, be not limited to when forming film supporting member 3, preformed film structural component 2 be carried out integrated, also can when forming film supporting member 3, carry out integrated film structural component 2 by additive methods such as compression forming method or casting methods by injection molding.In addition, film structural component 2 and film supporting member 3 fixedly all-in-one-piece situation such as be not limited to utilize to insert be shaped, after forming film structural component 2 and film supporting member 3 in advance respectively, also can be under no tension force or utilize mode such as bonding, that screw is fastening to be fixed on the film supporting member 3 film structural component 2 with the also weak tension force of the tension force more required than structure 1.

Here, as film structural component 2 that will form respectively in advance and the 3 incorporate measures of film supporting member, can use various measures.For example, can form the film supporting member 3 that the surface has projection, carry out integrated at the rise to the bait periphery of biofilm member 2 of this projection.Perhaps, also the periphery of film structural component 2 can be bonded on the surface of film supporting member 3, or fastening or stapler fastening means is carried out integrated with the screw of bolt etc.

Also have, as shown in figure 31, also film structural component 2 directly can be made or welding or be bonded on the surface of film supporting member 3.Here, be hook-like though film supporting member 3 is made the cross section, be not limited to this, also film structural component 2 directly can be made or welding or be bonded on as shown in Figure 2 the film supporting member 3.In these occasions, film supporting member 3 preferably makes by methods such as double-colored shapings, has to be suitable for film structural component 2 made or 2 kinds of materials of the 3f of frame portion that welding or bonding installation portion 3e and structure 1 possess necessary intensity.As installation portion 3e,, with being the material that makes easy fusing, be to make bonding material easily for example for bonding usefulness for welding for making with being the material that makes the softness of making easily.Like this, can strengthen with film structural component 2 between engage, can make structure 1 have necessary strength.

As mentioned above, film structural component 2 is directly being made or welding or be bonded in occasion on the film supporting member 3, owing to also needn't when being installed in film structural component 2 on the film supporting member 3, give film structural component 2, so can easily carry out manufacturing operation as the desired tension force of the product of finishing.And wire rod of making or bonding agent are olefine kind resin system or polyester, structure 1 integral body can be carried out recycling with keeping intact, so preferable.

In addition, shown in figure 32, because film supporting member 3 more is positioned at the circumference of film structural component 2, so also available fixed part 29 is by making or welding or bondingly fix between the film structural component 2.Here, as film supporting member 3, for example also 4 rod member can be combined into to exercise and use.At this moment, under the state that film structural component 2 is installed on each film supporting member 3, be configured to rectangle and be fixed on the framework 4.Then, 2 heating obtain tension force to film structural component.Adopt this mounting means, owing to film structural component 2 is reeled once, so when load acted on film structural component 2, film structural component 2 was hooked on the film supporting member 3, can strengthen installation strength on film supporting member 3.In addition, by with modes such as bonding or welding, screw are fastening that cover member 13 is integrated, thereby seat or backrest etc. obtain rigidity.Before being carried out heat treated, film structural component 2, after the frame shape thing of standing the rigidity of film structural component 2 tension force is finished, just can give film structural component 2 Necessary Tensility with cover member 13 incorporate occasions.Owing to not only can but also can bear the load that acts on the film structural component 2 by cover member 13 or with the integrated part of framework 4 by fixed part 29, therefore, the intensity of fixed part 29 also can be less.At this moment, also can be by injection molding that film supporting member 3 and film structural component 2 is integrated inexpensively.

In addition, as Figure 33 and shown in Figure 34, also available half member that is divided into two along its length 31,32 constitutes film supporting members 3, utilizes bonding between them or screw is fastening, chimeric or mode such as make sandwiches the periphery of film structural component 2 and makes integrated.As half member 31,32, can use drip molding or extruded material, with 2 identical shaped writing board shapes like that as shown in figure 33, or also can be as shown in figure 34, a side be that the cross section is half member 32 that half member 31, the opposing party of L font is mounted in its inboard even shape.In addition, the contact-making surface between each half member 31,32 is not limited to tabular surface, also can make to have tiny concavo-convex face.At this moment, the power that can strengthen bonding or welding or make.

Shown in Figure 35 A～35B, also can use film supporting member 3, and it is made of half member 31,32 that forms protuberance 31a and recess 32a on face relative to each other.Between protuberance 31a and recess 32a, carry out chimericly by film structural component 2 is sandwiched, and can more strengthen the confining force of film structural component 2.In addition, be preferably in the front end formation projection 31b of protuberance 31a.Like this, by the part of fusing projection 31b, can carry out welding securely with recess 32a.Perhaps, also projection 31b can be inserted film structural component 2, also can seek anti-avulsion this moment.

In addition, also can be installed in groove or the pawl of using on the framework 4 being pre-formed on the film supporting member 3,, film supporting member 3 is installed on the framework 4 in that film structural component 2 is sandwiched under the state on this groove or the pawl.At this moment, also can be for example the periphery of film structural component 2 be wrapped on the framework 4 in advance, landfill film supporting member 3 from it, or under the state of the groove of in advance periphery of film structural component 2 being put into film supporting member 3, with film supporting member 3 landfills in framework 4.At this moment, heat after being installed in film structural component 2 on the framework 4.In addition, in this occasion, also available chimeric fastening force is film supporting member 3 and framework 4 fixedly, or utilizes screw fastening etc. that film supporting member 3 and framework 4 is fixing.By the fastening grade of screw film supporting member 3 and framework 4 fixedly the time, are made bolt perforation film structural component 2, the further confining force of strengthening membrane member 2 of the fastening usefulness of screw.Also have,, film structural component 2 can be sandwiched between these protuberances and recess by forming mutual chimeric protuberance and recess between the groove of film supporting member 3 and the framework 4, thus the further confining force of strengthening membrane member 2.
