Description
Technical field
The present invention relates to a kind of surface fastener and prevent intrusion device, above-mentioned surface fastener has some protruding formula joint elements (male engaging elements), described protruding formula joint element is made up of a plurality of hook-shaped products, the recessed formula joint element of ring-type (female engaging elements) of a lip-deep cooperation of above-mentioned hook-shaped its flat base member of product joint, above-mentioned prevent intrusion device at least on the longitudinal direction of basal component along left side and right side edge part, be used for when molded this product, stopping that a kind of molded resin material invades a joint element and form the district.
Background technology
Passenger's seat in automobile or the train, and various sofas and office's seat all have a kind of pad (cushion body) in their skin material inside.As this pad, adopt so-called asbestos or various molding, above-mentioned so-called asbestos are by with the monkey grass of various rigid fibers and flax or synthetic fibers tangle and harden with rubber or analog and to obtain, and above-mentioned molding is made with various expandables materials.These gasket materials have a curved surface, and above-mentioned curved surface comprises convex and the female shapes that satisfies the ergonomics factor, so that keep a kind of posture that is seated, also do not feel tired although described posture is seated for a long time.Make the gasket material that has this complex surface shape in a large number effectively if plan to consider its gasket performance, then require the above-mentioned asbestos of many manufacturing processes not satisfy the demand.In contrast, the pad of various Foamex systems has been extensive use of, because it can be with a procedure manufacturing, and can be easy to obtain diversified shape.That is to say,, simultaneously the expandables pad is molded as a kind of desirable shape when by a kind of expandables material such as a kind of polyurethane resin of sending out are poured into when foaming of inducting in the mould.
Various fiber cloth or natural leather or synthetic leather skin material be applied on the surface that in this way forms and with described surface becomes integral body.For this integration, used wherein a kind of expandables material has been poured into a device in the mould, above-mentioned mould has a kind of skin material that absorbs along die surface, so that when execution is molded, make the rear surface of a pad and skin material form integral body, perhaps use wherein after forming a kind of pad of expandables material, skin material is applied on its surface and the device that is fixed thereon with a mould.
According to above-mentioned a kind of Unitarily molded method, when skin material when the inner surface of mould is installed, it is absorbed device and absorbs.When skin material during along with the areal deformation of the pad with complicated structure, skin material must be material itself have fabulous stretching may.Yet, because a kind of stretch limit that depends on material is arranged,, and up to now, made very big effort between a seat surface and a perimeter side surface so that remedy this phenomenon so a lot of fold tends to especially produce.
In addition, because this Unitarily molded method forms backing material and skin material on their whole surfaces whole, if so for example apply a brute force towards a direction, on the above-mentioned direction between the actual operating period skin material at the surperficial upper deflecting of pad, then between skin material and pad, produce a kind of shearing force, pad usually partly tears and makes then skin material separately.Usually automatically be restricted as the material of skin material so that get rid of the generation of this class fold, and preferably can be between skin material and pad light exercise so that between them, do not apply any excessive power.For this reason, replace making skin material form integral body in molded pad, a kind of method that skin material is applied on the molded in advance pad has become very popular.
Skin material is applied to conventional method on a kind of pad of expandables material system as a kind of being used for, the joint element of surface fastener is formed the surface to be placed and is fixed on the surface portion corresponding to a protrusion at the bottom of the mould of a pad concave surface, so that it is relative with the surface portion that protrudes to make joint element form the surface, in mould, pour into a mould a kind of expandables material then, so that at a kind of foamed state lower mould pad, and simultaneously surface fastener is embedded in the concave surface of pad and becomes integral body with it, and above-mentioned pad has some joint elements that are exposed.When this foaming is molded, prevent that the expandables material from flowing into a joint element and forming the district.To be applied to the surfacing that various materials are made as fluffing woven/knitted fabric, natural leather and synthetic leather with on the molded pad of said method, above-mentioned various materials are made a kind of bag shape, and the shape of described bag is corresponding to the shape of pad.Then, pasting and become whole surface fastener joint element with pad and form the surface,, and preventing the pad rise so that skin material is bonding and fixing along the concave surface of pad with being arranged on recessed formula joint element on rear surface of skin material.
Invade joint element and form the district in order to prevent the expandables material when the molded pad, normally prevent that along the periphery setting of the basal component 102 of a surface fastener 101 the expandables material from invading wall 104,105, so that surround many joint elements 103, for example at United States Patent (USP) the 5th, 061, No. 540 and 5, disclosed reaching as shown in Figure 13 and 14 in 766, No. 723.Same symbol and like numerals will append on corresponding symbol and the label.
On the other hand, recently, the form of a kind of surface fastener with a kind of band formed continuously.Even in this case, also on the width of a surface fastener, prevent from vertically to invade wall along right side and whole formation of left side edge part, so that use and U.S. Patent No. 5,766, identical method in 723 is enclosed in formed many joint elements on the single side of flat base member from right side and left side.Therefore, the intrusion that prevents a kind of expandables material is invaded a joint element formation district from a side direction (width) direction, in addition, along a longitudinal direction joint element is formed the district and carry out segmentation, and one second of formation prevents to invade wall between adjacent segmentation, so that it extends, therefore prevent of length (vertically) the direction intrusion of expandables material from surface fastener on width.Be used for the expandables material and respectively prevent to invade the height of the height setting of wall greater than the joint element that surrounds.
When molded pad, as mentioned above, surface fastener is placed like this, so that joint element forms the surface portion of the protrusion on the aligning mold bottom of surface and is fixed thereon and then, the expandables material is poured in the mould.When cast expandables material, the intrusion of expandables material is by preventing that invading wall stops, describedly prevents to invade wall and holds up the some joint elements that are used for surrounding each segmentation, and therefore, prevents that the expandables material from invading joint element and forming the district.Treat that forming the rear surface and prevent of whole surface fastener by its basal component by molded and pad invades an outer wall surface of wall and be adhered on the pad and with pad and become integral body.So, do not have expandables to invade joint element and form the district, and therefore, exercise a kind of adhesive function of surperficial fastening zone reliably.In order to guarantee a kind of bond strength between pad and the surface fastener, when molded surface fastener, its rear surface forms a kind of surface of injustice, perhaps makes a kind of supatex fabric and rear surface become integral body.
For each joint element being placed and firmly is fixed on a pre-position of the surface portion that protrudes on the mold bottom, usually a permanent magnet is arranged on the base member of surface fastener, perhaps a permanent magnet 108 is embedded in the part corresponding to the mould of a surface fastener placement location, and simultaneously a magnetic 109 is arranged on the basal component of surface fastener, as at United States Patent (USP) 5, such in 766,723.Therefore, by a kind of magnetic pull of utilizing magnet 108 surface fastener 101 is located and is fixed on a placement location place of surface fastener 101 exactly.Permanent magnet or magnetic form the form of a kind of band, wire shape or bar usually, and use a kind of synthetic resin of material as mixing with a kind of ferrite magnet or magnetic powder of excellent elasticity.As magnetic, adopt a kind of thin-band material or wire rod of steel, and in molded surface fastener, this material is embedded in the basal component.
As mentioned above, in U.S. Patent No. 5,061,540 and No.5,766, in 723 disclosed surface fastener expandables material vertically prevent invade wall the basal component joint element form the surface width on form continuously along two lateral edge portions, and prevent that with one side direction from invading wall and being set to along the longitudinal direction of basal component and forming in the segmentation of formed each predetermined number joint element in the surface at the joint element of basal component, so that it forms between adjacent segmentation.This side direction that prevents is invaded wall and always is not limited to one, but can two of parallel formation prevent side direction intrusion wall.Because vertical and side direction prevents to invade the existence of wall, so when the molded pad of foaming, stop from vertical and lateral and invade the expandables material.As a result, stopped that fully the intrusion joint element forms the district.
As mentioned above, in recent years, generally be on the periphery surface by an injection moulding or extrusion molding resin to a mold wheel continuously, monoblock type and form many joint elements continuously on a kind of surface of band-shaped substrate member, above-mentioned mold wheel comprises some die cavitys that are used for molded many joint elements and prevent expandables material intrusion wall, and mold wheel is rotated towards single direction simultaneously.Yet, even the molded surface fastener that obtains in this way is long, but owing to prevent that a kind of interval of side direction intrusion wall is definite according to the external diameter of mold wheel, so should repeat by a kind of compulsory figure at interval.
On the other hand, for example, in passenger's seat of automobile, on a surface of seat, form a kind of surface that comprises the injustice of a suitable curved surface, so that guarantee to think the posture that is seated of the most comfortable from the ergonomics viewpoint.The structure on the surface of this injustice, especially its length are not changeless, but can change.Molded surface fastener becomes integral body along the concave surface part that one of the pad that has a non-planar surface is seated surperficial with a pad.When covering pad with skin material, by add depress will comprise a recessed formula bonding pad of skin material rear surface fovea superior formula joint element form the district with the joint element of surface fastener and be connected, surfacing is installed on the pad, so that it is stretched tightly.
If plan to install a kind of banded molded surface fastener with the said method continuous molding.Its length is different from the length of corresponding pad concave surface part, then long molded surface fastener must be cut into predetermined length before using.Because cutting position at this moment is the length decision according to the concave surface part, so Cutting Length is always not identical.Therefore, surface fastener usually must form cutting in the district by joint element in a segmentation, and above-mentioned segmentation is invaded wall and separated by the side direction that prevents with a predetermined number joint element.If surface fastener is cutting in composition surface forms the district, then the expandables material is invaded a joint element that cuts and is formed the district, and therefore, each joint element in this district is imbedded in the expandables.Therefore, each its function of joint element loss in the zone that expandables is invaded as joint element, and therefore, can not guarantee the bonding force of original needs when a surface fastener is cut into a predetermined length.
Especially, in above-mentioned U.S. Patent No. 5,061,540 and No.5,766, in the 723 disclosed conventional surface fasteners, the formed side direction that prevents is invaded wall and insertion and is prevented that side direction from invading the interval between each adjacent bond element of wall in the adjacent sectional, is generally equal to joint element and forms the interval between formed each joint element in the district.In addition, because in these intervals, do not have the joint element existence and prevent side direction intrusion wall thickness, so do not apply bonding force.As a result, it becomes and more is difficult to obtain desirable bonding force.
Summary of the invention

The passage that formed gap was used as a kind of expandables material that injects a mould (not shown) when molded gasket between formed interval and the adjacent partition wall 5 between vertically wall part 4 was respectively arranged.The expandables material forms district's direction around each partition wall portions 5 towards joint element and invades gradually by each gap with at interval from the width of molded surface fastener 1.Arrive at the expandables material before first vertical wall part 4a in a most close joint element formation district, it hardens with a kind of swelling state, and does not arrive joint element formation district.As a result, it is bonding by this way and fixing, so that it surrounds all partition wall portions 5.At this moment,, cross partition wall parts 6, invade the partition wall parts 6 inner formed intervals between vertical wall part 4 then so invade the expandables material of vertical wall part 4 because partition wall parts 6 are lower than partition wall portions 5.As a result, partition wall parts 6 are imbedded in the expandables material.Therefore therefore, partition wall parts 6 are imbedded in the pad, increased constant intensity between molded surface fastener 1 and the pad (not shown) by so-called anchoring effect.
Formed many joint elements 3 are erected in the multirow of the width that strides across basal component 2 in joint element formation district.As shown in fig. 1, by a lateral sidewall part 7 three row's joint elements 3 are defined as a segmentation, described lateral sidewall part 7 is characteristic parts of the present invention.As shown in Fig. 1 and 5, each joint element 3 comprises that all one rises part 3a and an engagement head 3b, above-mentioned rise part 3a upwards rises, and engagement head 3b extends on the longitudinal direction of basal component 2, its front end is to be bent downwardly from the top of rising part 3a simultaneously, thereby a kind of hook of whole formation.In this embodiment, as shown in Fig. 1 and 5, two adjacent on basal component 2 widths joint elements 3 all have engagement head 3b, and described engagement head 3b extends with relative direction with the back in a longitudinal direction forward.The wherein a pair of of these joint elements 3 becomes one by the rise part 3a side surface with same shape.6 pairs of joint elements 3 become delegation to hold up on the width of basal component 2.Certainly, the shape of each joint element 3 is not limited to an example of pointing out and in addition, and the joint element number that becomes delegation to arrange also is not limited to pointed example.
In the lateral sidewall part 7 that is characteristic of the present invention, as Fig. 1, shown in 4 and 5, between vertical wall part of holding up on two lateral edge portions on the width of basal component 2, a lateral sidewall 7a extends across basal component 2 linearities.Lateral sidewall 7a equals the height of vertical wall part 4 from the height on basal component surface, and the maximum height of vertical wall part 4 and lateral sidewall 7a is set the peak height that is a bit larger tham joint element 3 engagement head 3b for.The wherein part of the rise part 8a of joint element 8 has the shape identical with above-mentioned paired joint element 3, and whole joint element head 8b in overall fixed on the longitudinal direction of basal component to the preceding and rear surface of lateral sidewall 7a so that the front end of engagement head 8b separately staggered in the opposite direction towards back and the place ahead to.The height of engagement head 8b equals above-mentioned and forms the height of the engagement head 3b of formed joint element 3 in the district at joint element.
According to this embodiment, the joint element on a lateral edge portions on 3 wire magnetics 9 and basal component 2 widths and the middle body of basal component 2 forms the surface and fuses into integral body so that their in a longitudinal direction wire extend.As wire magnetic 9, the monofilament that adopts a kind of synthetic resin that is mixed with magnetic to constitute, above-mentioned magnetic is made up of a kind of alloy such as iron, cobalt and nickel.According to this embodiment, be to get the surface fastener installed position that a magnet is placed on a mould that is used for molded pad although use above-mentioned linearity magnetic 9, also available shaped like narrow metal forming replaces a thread like body.If do not place magnet, then a wire or banded magnet directly can be fixed on the basal component 2 and replace magnetic at the mould that is used for molded pad.
If wire magnetic 9 a wherein part becomes integral body with basal component 2, so that be exposed on the surface of basal component 2, be used to guarantee a underlying structure intensity, if apply a slight external force, then wire magnetic 9 tends to separate with base member 2.Therefore, according to this embodiment, the becoming whole zone with wire magnetic 9 and form thickly in a longitudinal direction of base member 2.According to this embodiment, as shown in Fig. 2 and 3, thick part on the part of both sides of the edge is formation in the vertical wall 4 of three rows on vertical wall 4 is low than each partition wall parts 6 and basal component 2 widths, has two pairs of joint elements 3 corresponding to one of them the thick part of basal component 2 one of them in the middle body on width of wire magnetic 9.The engagement head 3b that is arranged on two joint elements 3 of these two pairs of joint element 3 outsides extends in the same direction, and two joint elements 3 that are arranged on the middle part extend towards the direction opposite with above-mentioned joint element, and the proximal part that is positioned at two adjacent bond elements 3 at middle part combines with a stop member (block piece) 10 and becomes integral body.
Being arranged on two wire magnetics 9 on the lateral edge portions on basal component 2 widths is separated wall part 5 and partition wall parts 6 respectively and surrounds and become integral body with them, the result is, partition wall portions 5 and partition wall parts 6 form the thick part of basal component 2, separate so that prevent linear magnetic 9 and basal component 2.Therefore, partition wall portions 5 and partition wall parts 6 have be used for stopping the function and the function that is used to prevent that wire magnetic 9 from separating with basal component 2 that the expandables material is invaded when molded pads.On the other hand, the part outer surface that is arranged on the wire magnetic 9 in the middle body on basal component 2 widths is surrounded with the stop member 10 that is connected joint element 3 by two pairs of joint elements 3 and becomes integral body with them.Therefore, the thick part of basal component 2 is formed by two pairs of joint elements 3 and stop member 10, thereby prevents that wire magnetic 9 and basal component 2 from separating.Attract because be fixed to the magnetic pull that wire magnetic 9 on the basal component 2 is fixed to the magnet on the mould (not shown) that is used for molded pad, so become a kind of molded surface fastener 1 of belt like shape accurately and securely to locate and be fixed on the preposition.
Simultaneously, magnetic needs not to be the wire shape, and can be for example a kind of band metal thin plate.Alternatively, this magnetic can separately be fixed.In addition, can be with a magnet without magnetic.For this magnetic or magnet are fixed on the molded surface fastener 1, allow basal surface with magnetic resin such as a kind of resin adhesive that mixes with magnetic or lacquer type organic coating coated substrate member 2, on basal component 2, form a magnetic film layers, perhaps by magnetic is mixed into basal component 2, joint element 3, vertically wall part 4 and lateral sidewall part 7 form the superimposed laminate layers in surface in one of them, perhaps a kind of resin bed that contains magnetic is laminated on the top surface of lateral sidewall part 7.As mentioned above, these processing are not limited to magnetic, and can handle equally magnet.
A kind of continuous notes mouth that is used for molten resin is provided, so that relative with the periphery surface of a mold wheel (die wheel), above-mentioned mold wheel is rotated towards single direction.Many die cavitys that are used to form joint element form in the central area of mold wheel periphery surface, and are used to form partition wall portions 5 and partition wall parts 6 are forming on two lateral edge portions on the axial direction of periphery surface, so that they extend intermittently.In addition, being used to form plurality of side forms therein in the zone of each joint element with die cavity to a plurality of die cavitys of wall part 7 and forms.The die cavity that is used for lateral sidewall part 7 is parallel to a rotation extension of mold wheel with a predetermined phase angle on peripheral direction.On the other hand, the part without interruption that will be used for wire magnetic 9 is arranged on a peripheral part upstream side place of mold wheel on the direction of rotation relative with annotating mouth.Then, wire magnetic 9 is fed on the position relative with mould alternate water injection mouth from supply section continuously.At the inner supply coolant of mold wheel, so that always cooling die is taken turns.In addition, following half part with this mold wheel immerses in the cooling bath described below.
In a kind of continuous manufacturing apparatus of molded surface fastener, a kind of molten resin material is expelled on the periphery surface of mold wheel continuously from continuous notes mouth with said structure.At this moment, mold wheel is rotated towards single direction, and the basal component 2 of surface fastener is formed by the molten resin on the periphery surface in the gap that is injected between mouth and the mold wheel.Simultaneously, each joint element 3, vertical wall part 4, partition wall parts 6 and sidewall sections 7 one after the other use die cavity separately to form.This when molded, each wire magnetic 9 on the mold wheel direction of rotation with respect to being added to injection position from the upstream side of annotating the moulded resin injection direction that mouth injects.According to this embodiment, because 2/3 being exposed on the surface of base member 2 basically of each wire magnetic 9, so except above-mentioned die cavity, form 3 gathering sills that are used for wire magnetic 9 on the peripheral direction in the mold wheel periphery surface continuously.
Therefore, in basal component 2 surfaces of the molded surface fastener 1 that becomes a kind of continuous belt like shape also to form in a manner described, surface with the some joint elements that form thereon, be the lower face that following 1/3 of each wire magnetic is embedded in basal component 2, a top surface of each wire magnetic 9 is partly used joint element 3, vertically one of them covering of wall part 4, partition wall parts 6 and lateral sidewall part 7.When molded above-mentioned molded surface fastener, each wire magnetic 9 is fixed on the surface of basal component 2 continuously simultaneously, and becomes integral body with the surface of described basal component 2.Molded surface fastener 1 is supported by the periphery surface of mold wheel, and carries half turn under a commentaries on classics situation of mold wheel.When carrying, its cooling and sclerosis separate with this periphery surface by the periphery surface that tightens up roller cooling and sclerosis mold wheel, are transported to a winding process subsequently then.
In above-mentioned example, the joint element of basal component 2 forms the surperficial 2a that surperficial rear surface forms a kind of injustice.The reason of doing like this is the bond area that increases Foamex, so that strengthen a kind of bonding force.Uneven surperficial 2a can be easy to form by a backer roll (not shown) that has a large amount of unevenness (uneveness) in its periphery surface is installed by this way, so that backer roll is relative with the periphery surface of mold wheel by molded surface fastener after molded.Although backer roll can be along with the mobile rotation of molded surface fastener, it is synchronous to be more preferably the rotary speed that drives it and mold wheel.Certainly, the rear surface can form smooth rather than uneven surperficial 2a.
In order to make molded surface fastener of the present invention 1 become integral body with a pad (not shown) of making by the expandables material by this method manufacturing, a kind of molded surface fastener 1 of growing continuous band-shaped shape is cut into desirable length, and the segmentation of cutting placed like this, so that the surface portion of the protrusion of the surface that each joint element 3 forms thereon in a mould (not shown), the surface portion of described protrusion is corresponding with a concave portions in the pad.A magnet (not shown) is embedded in the surface portion of mould protrusion, if and molded surface fastener 1 is placed on the surface portion of protrusion, then by a gravitational attraction of magnet, a kind of desirable posture of molded surface fastener 1 usefulness absorbs and is fixed on the surface portion of protrusion molded surface fastener 1 automatically then by wire magnetic 9.
A kind of expandables material is poured in the mould, and flow to each vertical wall part 4 and lateral sidewall part 7 of molded surface fastener 1 from the rear surface, be dispersed on the whole surface of mould, and foaming beginning simultaneously.At this moment, molded surface fastener 1 is located owing to the gravitation of magnet in the mould and is fixed, and its position flowing and can send out pressure and move because of the expandables material not.Although a kind of fluid inflatable resin material attempts to pass gap between each partition wall 5 of vertical wall part 4 of being made up of many rows and the gap between aforesaid each partition wall parts 6, invade the formation district of joint element 3 from the width of die surface securing member 1, but it is separated wall part 5 and partition wall parts 6 block, and therefore finishes its foaming and sclerosis before arriving joint element formation district.On the other hand, with regard to the longitudinal direction of molded surface fastener 1, a kind of molded surface fastener that obtains 1 must be cut into a predetermined length, as mentioned above.If lateral sidewall part 7 can be cut into two sections in a longitudinal direction at that time, then it is desirable.Yet required cutting part length is always not identical.In addition, in the surface fastener that forms continuously as mentioned above, the interval between each lateral sidewall part 7 can not change arbitrarily.Therefore, molded surface fastener 1 usually is to cut in the formation district of joint element 3.
As a result, all the other districts that wherein only form joint element 3 under without any the situation of lateral sidewall part 7 exist on shearing end one side of the molded surface fastener of cutting.Yet,, can prevent to influence the whole length of the molded surface fastener of incision if regulate interval between the lateral sidewall part 7.If in mould, place and the fixing molded surface fastener 1 that cuts after, pour into a mould the expandables material as mentioned above, then the expandables material is invaded all the other districts, joint element 3 exists by an incision end of molded surface fastener in described all the other districts, and arrives a nearest lateral sidewall part 7 sometimes.Because this intrusion, the joint element 3 that exists in all the other districts is imbedded the internal structure of a foaming body, and becomes integral body with the internal structure of described foaming body.
As a result, owing to the constant intensity of 1 pair of pad of molded surface fastener is strengthened by anchorage effect, so the joint element that exists in all the other districts is useful.The expandables material prevents by lateral sidewall part 7 further mobile after arriving lateral sidewall part 7, and therefore, it does not arrive in the joint element formation district by each joint element of vertical wall part 4 and 7 encirclements of lateral sidewall part.After molded surface fastener 1 was fixed to a desirable place and becomes integral body with it, pad was used according to the described skin material of a kind of prescriptive procedure and is covered.By compressing a mounting portion of molded surface fastener, the recessed formula joint element on the molded surface fastener table of joint leather material rear surface so that skin material does not rise from pad, thereby accurately and is suitably installed along the curved surface of pad.
In the present invention,, but on its top surface, have the joint element 8 of some one-tenth hook-like shapes because lateral sidewall part 7 is not a kind of simple wall, thus the district of no any joint element be provided with, and unlike conventional molded surface fastener.Therefore, the almost whole surface of molded surface fastener 1 all is bonded on the recessed formula joint element that forms on skin material (the surface skin material) rear surface, so bond strength obviously improves.As a result, even on yawing moment a power is applied in the seat segmentation of skin material, skin material also is not easy to take apart.In addition, combine the light exercise that can adapt between skin material and the pad between molded surface fastener 1 and the skin material, and close differently with a kind of high strength yarn or toe-in, and therefore protect pad to avoid damage.
