Description

Production has the method for pad furniture, production pad furniture and basic structure thereof arranged

The present invention relates to produce the method for pad furniture, that produces in this way has pad furniture and basic structure thereof.

There is pad furniture generally to be similar to bed, produces and assemble as follows: at first do underframe underframe in other words, supporting leg also is installed thereon, its configuration for example, can be a frame-type, and the metal spring of preferably packing into therein, on described underframe, also supporting the frame or the framework of backrest.Liner also is housed, as on the spring bedstead of bed, loading onto mattress at last on this underframe.Finally with cover material package, for example the cover material anchors at the downside of framework for liner and framework.In this case, in fact liner can also be as the relevant figuration material of configuration, although its design freedom is limited.

This have the conventional structure of pad furniture to have several shortcomings.There is pad furniture will spend a large amount of time, with a large amount of different materials, almost assembling one by one.Its result, producing has the cost of pad furniture high relatively.And conversely, this furniture in fact can not recycling, will be and finally become with the raft rubbish of thermal treatment removing, because have corresponding routine pad furniture just so to split into single member, utilize in order to sending in due course again, if be not impossible also be uneconomic.

The present invention is intended to avoid conventional problem, the especially the problems referred to above that produce of producing of pad furniture, and proposes to have the different substantially structure of pad furniture.

According to the present invention, this problem-solving approach is as follows: arranging a kind of trend that only provides seat or backrest roughly basically near user's contact-making surface place that pad furniture is arranged, work the primary element of stablizing the effect of described backrest furniture, and settle the material that is suitable for moulding at the following and/or dorsal part of described primary element, reaching with this basically has pad furniture primary element down and/or the configuration moulding that pad furniture is arranged everywhere of back of the body contact-making surface.

According to the present invention, having pad furniture to construct basically with conventional has pad furniture different fully.In other words, its assembling does not take up from framework or primary element, upwards has been assembled into pad furniture by adorning liner thereon, and described liner not only determines the comfortableness of seating, also will be used as the figuration material.The method according to this invention will be produced has pad furniture to be actually to have utilized a kind of primary element, it is not near ground, but near contact-making surface, in other words, at first arrange from upper side more or less, here, it is to realize downwards that final also domination has the moulding of the configuration of pad furniture itself, because moulding does not change the comfortableness of seating, the free degree of moulding has strengthened.Here it is below corresponding primary element, or the rear is arranged to screw on screw in other words and is suitable for the material of moulding.Then, on primary element and figuration material, wrap cover material covering again, and, close at all each side seals, perhaps preferably to seat portion and the back part package of turning up the soil.Cover material covering, for example, can be by means of sealings such as slide fasteners, on stitching or the hook.In principle, for according to of the present invention have pad furniture can also downside not on cover material and do not constitute seal bootr material covering.

Primary element constitutes, and itself mainly is the seat face and the face of leaning on that constitutes pad furniture.Be to realize compliance, the face of seat district and (or) preferred (separately) frame-type design in Kao Mian district, the centre bore of frame loops coiled preferably seals through the material that stretches tight basically again.Therefore, the comfortableness of sitting usefulness is mainly produced by the material that stretches tight, and can design its elasticity and submissive ability, and can regulate, it is contemplated that equally at the material itself that stretches tight to add filler and core material, even the core material of deformable or inflation, material carries out certain additional moulding in order to stretch tight.Here, for example, the material that stretches tight can hang on the frame structure of primary element in whole sides by means of metal hook.Framework itself primary element itself in other words is stable as far as possible, and preferably with aluminium or timber manufacturing, for example, with shape or glued board or the manufacturing of solid wood material, beech wood is especially suitable for last construction form.Here, primary element can constitute single-piece, for example, can use the steam treatment bending as one sees fit, perhaps carries out other moulding.Primary element also can be many, for example sits face district and backrest district and can interconnect with metal angle section or analog and form.Like this, it is also contemplated that by means of hinge or analog adjusting backrest.Also can settle the core parts or the retaining element of handrail on primary element at least, can be the handrail moulding with above-mentioned moulding material also here, even use high density or high-strength material.

Preferably the figuration material of Shi Yonging is, the piece shape polypropylene of granular texture is arranged because containing polystyrene, can also cut into such polypropylene material certain shape and be used for moulding, preferably with the cutting of microcomputer control material processed machine.For reaching high density and high strength, polypropylene material can heat-treated and densification, also can carry out die forming to it here.

In addition, foamed material that all right liner of this primary element is common or other gasket material constitute contact-making surface easily with (more), thereby, with regard to total shape that pad furniture is arranged to be produced, primary element no longer directly prepares contact-making surface, but mainly as the stable core that pad furniture is arranged.Preferably adopt flat foamed plastics.

Contrast is conventional produces, and produced according to the invention have pad man to have various advantages.At first there is the general assembly of pad furniture to realize that by the single parts that are processed into voluntarily layman's labour also can implement fast and simply generally according to the present invention.Can directly prepare a kind of modular system, be assembled with pad furniture or carry out house fitting by it, here need only just can form with about five kinds different materials and part the pad furniture body is arranged, they are: a kind of irrelevant fully with the concrete configuration that pad furniture is arranged, in principle the same outward appearance and the primary element of structure can always be arranged, a kind of material that stretches tight of primary element, a spot of moulding piece that the seat of pad furniture is arranged with face, backrest face and handrail face, one to two contact-making surface filled and process material pieces and a kind of package have the body of pad furniture or the cover material covering of leg.

There is pad furniture to build so simply just as this, after reaching its service life, also can rolls over easily, can be the very like a cork mutual disassemble of each part here, and partly utilize and send to recovery simply again.Single-piece, quantitatively only limited parts can be processed outward and send to processed finished products again, with personnel that are subjected to seldom to train even automation ground general assembly.Here the desirable configuration of backrest furniture is mainly only determined by the figuration material, the figuration material can be sent to general assembly with corresponding preform, and all other parts can be gone design for, pure technology-functional part irrelevant, single with configuration in principle.Only determine the visual appearance of backrest material with the cover material.And itself is easy to select very much, and replaceable.

By this mounting technology that pad furniture is arranged, especially can be logically or simultaneously desirably control produce.The common mode of production that pad furniture is arranged but in contrast.For example, in the moulding field, furniture production firm " supposition client's taste " finishes the seasonal only not pad furniture that has, and shows to the consumer then.And pad furniture mounting means arranged for of the present invention, can determine the configuration of its furniture by the client voluntarily, and order pad furniture is arranged accordingly, thereby can have pad furniture to produce in a short time and deliver according to customized.

This is also especially suitable to the supporting leg that pad furniture is arranged.To this, the present invention's imagination is arranged in fixed area to the supporting leg of furniture, and they pass the figuration material, firmly is connected with the primary element that pad furniture is arranged.For example prepare the metal fixed head, can very arrive adaptive sometimes other furniture by requirement of client on it, fixing any supporting leg can be with inclination angle arbitrarily, fixes in position arbitrarily or with material arbitrarily, and can change.

Because being provided with, sits primary element with the comfortable material that stretches tight, and bear the person's that rides the seat weight, also play additional moulding effect, especially only do thick configuration arrangement at downside and dorsal part that pad furniture is arranged, so on concrete link, can also launch so additional decoration, just can realize thus fully more having the technology grace according to the simple and clear configuration that pad furniture is arranged of the present invention.The material that particularly stretches tight can be made of flexible braided material, and it can have noticeable appearance, thereby so visible dorsal part that pad furniture is arranged not is certain and aesthetic effect has nothing to do.(inventor) has this simple form of pad furniture to require independent protection to of the present invention.

The material that stretches tight can adopt, and for example, with the inelastic parallel braided material of warp springy that interweaves, thereby a kind of braid occurs, and it is flexible especially in one direction, and is ductile in other words, for example can reach 130% of longitudinal extension length.

,, stretch tight following of prestressing force and to expect to take in the primary element according to an improvement of the present invention for thereby the material that stretches tight when avoiding personnel to take excessively subsides and improves the comfortableness take.The compliance of material can make the figuration material have and seat type or analog respective recesses because stretch tight.

Primary element preferably is extensive use of aluminium and constitutes, and guide groove is especially arranged, and the aluminium section bar of T font guide groove for example can be in stretch tight the marginal zone wedge joint or the splicing of material.Certainly imagine with timber or plastic processing primary element.

And have the supporting leg of pad furniture directly to be bearing on the primary element, rather than be bearing in sometimes and say from statics, on the too unsettled figuration material.Pre-the opening of expecting of stretching tight can for example as be issued to: at first, two marginal zones of the material that stretches tight are placed on the longeron that moves towards in parallel to each other of primary element, widen the phase mutual edge distance of longeron then, the pre-thus material that stretches tight of opening.When the distance between longeron reaches desired frame size, load onto pillar, as the longeron of mutually tension apart from holding device, and by corner connector each pillar and longeron are interconnected at all four angles.This can preferably reach with the tenon joggle, and joggle can also guarantee the anti-rotation performance that the angle connects, thereby framework is played certain twisting resistance fixation.(inventor) proposes the independent protection requirement to the pad furniture of producing according to the method that has.

There is pad furniture to be characterised in that according to of the present invention, it has a framework, framework comprises two primary elements that form framework, primary element constitutes the skeleton of seat and backrest respectively and interconnects with predetermined angle, and at least mainly seals the material that stretches tight with the weight of bearing passenger in the frame openings that primary element constitutes.

Can obtain the described advantage that pad furniture is arranged of this method thus.

This have the preferred refinement of pad furniture to be provided by claim 16 to 21.

The framework that pad furniture is arranged is also proposed the independent protection requirement; this framework mainly is made of two frameworks; they interconnect and constitute the backrest of pad furniture and the supporting member of Cuo with predetermined angle; here, the inner opening of framework is at least mainly sat the material sealing of stretching tight of taking advantage of personnel's weight by bearing.

The preferred improved form of this framework is provided by claim 23 to 26.

The embodiments of the invention that embody further feature of the present invention are shown in the drawings:

Fig. 6 is the framework perspective view made from the described seat back frame of Fig. 1 that pad furniture is arranged, and on the seat frame schematic furniture leg is installed,

The angular region that furniture leg arranged of Fig. 7 for indicating with VII among Fig. 6,

Fig. 8 is the perspective view of one section on the total skeleton of sofa of the present invention,

Fig. 1 is the pad furniture frame element perspective view of framework element in other words that has of the present invention, and framework shown in Figure 1 here is a kind of seat back frame of sofa.

This frame mainly is made up of four edge strips, that is to say, is made up of with two vertical columns 2 longeron 1 of two levels, and here, column 2 and longeron 1 are interconnected by angle connecting device in the angular region, that is to say mutual joggle.The seat of sofa is provided with corresponding framework, here, seat back frame and seat frame, otherwise with predetermined angle, for example 105 spend angles, or interconnect with variable angle by hinge or folding band.

The seat frame of seat back frame shown in Figure 1 and sofa does not exist together and also is an intermediate longitudinal girder 4, and it is rigidly connected with its end face and column 2, for example, passes through screw; Perhaps by the corresponding type spare joggle on column or fixing.

No matter be longeron 1 and 4 or column 2 all has the long narrow tongue-and-groove of vertical trend on cross section, in Fig. 1, just schematically draw, but in other figure, show more in detail.These tongue-and-grooves can be used for fixing, and especially, bear the material that stretches tight of personnel's weight of taking, also are used for fixing the cover material of the structure of finally covering pad furniture.Just by so a plurality of tongue-and-grooves, can establish some type tenons and hook connection, utilizing them to be fixed on described stretch tight material or cover material in other words with simple mode hook almost is position arbitrarily, and can remove these afterwards very simply pad furniture is arranged, particularly in order to be recycled.At having in the pad furniture of this novelty, glue that need not be common and nail fully.Be arranged in the figuration material on the framework that constitutes by framework, also can install in the same way in existing moulding.Also be applicable to the supporting leg of pad furniture similarly, they directly are connected in the moulding, also are applicable to handrail or analog, and handrail also can be made the frame type with section bar here, and they can reach ground from seat sometimes.

The framework of framework surrounds each frame hole respectively, and these frame holes are widely with the flexible material that stretches tight, and for example, flexible braided material seals, the riding comfort of these braid final decision furniture and the weight of bearing the personnel that take.This material that stretches tight preferably is placed under pretension on separately the framework, here by notion as herein described, until last procedure of processing, that is to say and can also select to cover the back part that pad furniture is arranged of material and the arrangement of seat part to the end, can process fully apart from each other and assemble.

The utilization material bar that stretches tight in a broad sense, is to cut into foursquare fabric basically, respectively similarly stretch tight material pre-of the framework of seat and backrest is opened and installs.Stretch tight the material bar two marginal zones that are parallel to each other the hook bar is equipped with, on the hook bar hook spare is arranged, can be hooked in two be parallel to each other the trend longerons 1 or 1 and 4 in.By draw back these pairs longeron 1,1 or 1,4 stretch tight the material can open final desirable frame size in advance, fixed then and kept at a distance, wherein, earlier last of column 2 and longeron both sides is rigidly connected, and first elder generation of it and this pair longeron connected.

Backrest is gone up with seat and is adopted different longerons, and material is used to tack down.As shown in Figure 1, longeron 1 and only be used for the intermediate longitudinal girder 4 of backrest in the employing is with the material that fixedly stretches tight between these two longerons.And present place, its frame is only established two longerons 1, does not establish intermediate longitudinal girder 4, directly uses the material that stretches tight on these two longerons.As mentioned above, the framework that is used for backrest interconnects through an angle with the framework that is used for seat, is that the following longeron 1 of backrest is connected with the framework floor side member 1 of the seat of horizontal direction basically.A kind of special connector can be crooked bar, and its trend is, first joggle is in the column of backrest, and camber is comply with the camber of angle connecting device, changes over to then in the groove of column of seat.

The following equipment figuration of various sheths material is to produce and to constitute desirable designed size and the shape that pad furniture is arranged, here, according to the present invention, assembling is carried out downwards and backward, and framework is relatively near the passenger contact-making surface, and the liner through relative thin is cushioned again in case of necessity.As mentioned above, elasticity of self and the riding comfort of self stretch tight by framework itself and expect to realize.According to present technique, because the existence of two following longerons 1 of backrest and 4 can hold the cover material, the cover material lays in present district and the backrest district at last.Sometimes the cushion of laying on the present material that stretches tight is outstanding and surpass the following longeron 1 of backrest, and approximately prominent to the central longitudinal depth of beam.On the seat surface of described seat, lay the cover material, pass then between the following longeron 1 and intermediate longitudinal girder 4 of backrest, carry out downwards, and in the end, wrap up completely in the back zone stitching that pad furniture is arranged, here, the cover material on the handrail that is laid in sometimes also ends at the downside of seat, or foregoing edge of like that cover being expected is hooked on the moulding of seat frame by rights.

The cover material of backrest can be handled with similar mode, and cover material is laid on the contact-making surface of backrest here, and is certain on the last longeron of the backrest that is laid in backward and similarly pass down between longeron 1 and the intermediate longitudinal girder 4 then, on the corresponding cover material of being present.In this way, occur basic on topology two coating covers of sealing more or less fully independently, common known joint is arranged between liner and cushion.Also can apply with the cover material simultaneously and cover backrest, even not have the downside that is coated with pad furniture in case of necessity with sewing up, thereby this there is pad furniture for example also can freely carry out aesthetic layout in the space in the mode of custom.

Figure 2 shows that the exploded view of the broken folding brachymemma of longeron 1 and column 2.End region at this longeron is shown with the angle connecting device 3 that a fillet constitutes, and it has the joint tongue with connection effect 5 between angle connecting device 3 and longeron 1.

Not only as seen have by Fig. 2, for example both introduced in the longeron 1 for five, also introduce the joggle of the tenon 5 in the corresponding hole in the jockey 3, be also shown in the cross-sectional profiles of longeron 1.Same profile with angle connecting device.Longeron 1 and column 2 are provided with foursquare basically cross section, and wherein having introduced in foursquare side is the groove of T shape basically.Whole section bar can forge and press with the aluminium bar, and cutting or bending form then.Therefore undoubtedly can be very simple and produce this section bar economically, even the section bar of complex geometric shapes is more arranged.In the framework that has processed, groove 6 is annular, even if also all be continuous in the angle connecting device district, no matter provide superior fixed performance to the wadding braid or to the cover material that pad furniture is arranged.Here to cover material just for importantly, it is also holding the angular region and is fixing with laying, here, the cover material in the angular region shrinks in case of necessity, but can be along whole secure alignment.Hook bar on the cover material, for example, be sewn on the hook bar on the cover material edge, be arranged on the opposing edge of hook edge on the cover material with freely giving prominence to, on the angle of furniture, be provided preferably with a kind of zigzag tooth, it can make the moulding of annular can enter tongue-and-groove 6 without difficulty and turn and lean against this fillet place around the bent angle of jockey 3 realizes that hook connects, because pass through backlash, these realize that corresponding crooked tooth can more closely be close together mutually, and its material of while can automatically carry out some again and shrink back.Therefore in the angular region, the cover material of plane shear projected into and have more spherical geometries and do not need flanging to sew up or similar method, in the cover material, carry out, and can closely be connected on the whole length of framework in very simple mode.Certainly, also can realize, on the corner strengthen the bending of backlash, and the tooth of connection strap is pushed open mutually, the material in the corresponding buckled zone be done some extended or elongation.

Fig. 3 A and Fig. 3 B show angle connecting device 3 again one time, shown in Fig. 3 A be that joint tongue 5 does not also have the exploded view that inserts, and joint tongue have inserted among Fig. 3 B.

Fig. 4 represents the cross section of amplification of the section bar of longeron 1 or column 2 again.The cross sectional shape of the tube seat that runs through 7 of the shape of cross section of especially visible tongue-and-groove 6 and insertion joint tongue 5 usefulness among the figure.

Fig. 5 still shows longeron 1 perspective view of a segment type material of column 2 in other words with cross section shown in Figure 5.

Figure 6 shows that framework according to sofa of the present invention, it is made up of seat back frame shown in Figure 2 and the similar seat frame that superincumbent horizontal direction orientation is installed, in Fig. 6 in order can to see clearly, the longeron of framework and column not proportionally chi draw, but exaggerated thickness.

Same parts are marked with same label in the figure that successively occurs.

Two frameworks are with predetermined angle, and for example 105 spend angles, and interconnecting becomes framework.This connection can be adopted the gusset of being with thread or analog in theory, also can connect with hinge, and to change angle, still preferred scheme is, moves towards the connecting rod of bending with tongue-and-groove at end sections tenon in tongue-and-groove of framework.The bar of such rigidity, for instance, earlier along with the trend of the groove 6 of the column 2 of seat back frame, insert downwards and then along with the prolongation trend of the tongue-and-groove in the angle connecting device 6, steering base direction forward more at this point, and change the trend that continues in the column tongue-and-groove 6 of the seat frame after continuous with tongue-and-groove 6 over to.Also occur a kind of grafting joggle in other words thus, here, having tenon only need have the thundering form of moving towards.Such tenon formula is pegged graft and has been utilized tongue-and-groove 6 in superior mode once more.In theory, can also use gusset or analog to connect backrest and seat in end side certainly, perhaps, for example, use and make prismatoidal template, the angular region of framework is put in to screw down.But insert connection by this preferred tenon and can not destroy the whole joggle design that pad furniture is arranged.That is to say in these positions and also needn't return to common interconnection technique.

Among Fig. 6 the preceding angular region of seat, a supporting leg of the sofa that exemplarily draws.This leg clearly draws in Fig. 7 once more.

At first the structure of supporting leg contains a set square 8, and it inserts the angular region of seat frame and is fixed on herein.Described plate 8 has a screw hole 9, can insert connecting screw by it a middleware 10 is connected on the plate 8.It is own to connect supporting leg 11 again with described middleware 10, for example connects with screw.These supporting legs 11 are prepared with its moulding by the configuration decision of backrest furniture, and can, tilt to lay as shown in the figure.Connection between middleware 10 and the supporting leg 11 for example, can also connect by another kind of screw, and wherein, for example, whole middleware 10 has internal thread and supporting leg 11 has external screw thread.Can also design the height and the adjustable in length of leg structure with simple mode.

Middleware 10 mainly only plays a transition role, and finishes the firm connection between supporting leg 11 and the seat frame.Middleware 10 is by arranging the figuration material parcel that constitutes pad furniture spatial form below the present frame, also preferably joggle in the tongue-and-groove of frame structure.Therefore middleware 10 passes described figuration material, arrives at a frame, thus figuration material holding capacity not itself.Very clear, to decide on the thickness of figuration material, middleware 10 can also have length arbitrarily, here, for the total height that does not strengthen seat for example can connect short supporting leg 11 with long middleware.

Figure 8 shows that the perspective view of the overall structure of one section sofa of the present invention.

Still interconnective seat back frame shown in the figure and seat frame, but sealing frame hole has been arranged herein and born the material 12 that stretches tight of the weight of passenger.

In addition, also can see the arrangement of the leg structure that supporting leg 11 forms, middleware 10 provides the space for the figuration material that is arranged in below the sofa face here, thereby can only see supporting leg 11 itself later on.

Can also see the framework of the handrail 13 on the column 2 of fixing the present frame of assembling among Fig. 8.This handrail framework also is made up of the little frame that a longeron and column constitute, and does not add detailed description for simplicity, can lay the figuration material of handrail on it equally.

In sum, the present invention relates to a kind of pad furniture that has ingenious, its framework and manufacture thereof, here the present invention is intended to reconstruct a kind of pad furniture that has in global design, and illustrate diversified configuration possibility thus, realize simultaneously a kind ofly being easy to reclaim, and the element mode of production that logically drops into city's field boundary better.It reaches like this, has pad furniture to set about assembling covering moulding again from a kind of framework, and here, the riding comfort of described backrest furniture does not rely on covering, but reaches by the material that stretches tight on framework.The assembling mode that pad furniture is arranged with this novelty, logical handrail form only is an annex with the supporting leg that pad furniture is arranged, and in common furniture construction, can say so, supporting leg should be regarded the basis that pad furniture is arranged as, and it should at first be connected on the framework and support this framework.All other then upwards with different materials, by fill, assemblings such as plug is slotting, stitching, ailing.Its danger is, or makes good configuration, and might take uncomfortablely, or make good riding comfort, but outward appearance is not good, but also needs multiplely expend high process, and often very heavy.

For liner furniture according to the present invention, the framework that core is made up of widget, framework is preferably formed with the connector system form, can optionally comprehensive equipment figuration material or configuration annex, even can assembling than later stage individually according to client's hope equipment.Can be the original too much expensive stock of configuration element and cancel always similarly by the standard fabrication primary element thus.Can also be with simple mode by existing primary element or framework in each piece of furniture be connected simply, independent seat one piece of furniture that crouches is combined with living environment arbitrarily.
