Abstract
In a synthetic resin molded surface fastener, each of a multiplicity of engaging elements has a stem standing on a front surface of a substrate sheet and a horizontally expandable and shrinkable engaging head continuously formed on and horizontally bulging from an upper end of the stem. The engaging head is divided into two or more segments resiliently bendable toward and away from one another. When the engaging head engages a respective one of engaging heads of a companion surface fastener, each of protuberances projecting from the front surface of the substrate sheet centrally between four adjacent ones of the engaging elements comes into the gap between the segments to bend the segments away from one another, increasing the entire diameter of the engaging head so that the engaging elements can be engaged with those of the companion surface fastener stably without rattling.
Description
The present invention relates to the synthetic resin molded surface fastener of a kind of thermoplasticity, particularly a kind of being suitable for and the surface fastener of the die casting of the surface fastener secure engagement of the die casting of the same structure paired with it.
The synthetic resin molded surface fastener that connects by extruding since they be easy to connect and have the bonding strength of height to be widely used for connecting industrial materials and upholstery product especially.Generally, attaching parts comprise the surface fastener of formpiston casting, many hook-shaped or mushrooms eat the shape engaging element by die casting and stand on the front surface of substrate in positive fastener, also comprise the surface fastener of former casting, and many annular engaging elements stand on the front surface of substrate in cloudy fastener; The two mating surface of positive and cloudy surface fastener pushes toward each other and meshes.Normally cloudy surface fastener is the style of weaving or woollen yarn knitting scrim.In the attaching parts of this combination, cloudy engaging element with the positive engaging element engagement of the surface fastener of fiber ring set form and die casting not only is easy to damage but also elongate on the direction that improves in engagement process in stripping process, takes sound and closely links together to such an extent as to make the interval that stays between the Yang Heyin surface fastener two surface fasteners too far away can have card.
In order to guarantee that high joggled strength is arranged and do not have any damage or do not have card and take sound ground engagement between the Yang Heyin engaging element, have the clear 47-11770 of patent Nos. that the synthetic resin molded surface fastener of the Yang Heyin of basic identical fit structure has been published in for example Japan, disclose among the clear 52-51242 peace 3-286702.
The surface fastener of the die casting that discloses in the clear 47-11770 of Japanese patent publication No. has many engagement post, and each engagement post flatly protrudes from the upper end of each post on the substrate front surface.When engaging element and paired with it identical shaped engaging element interact, each engagement post part of horizontal ground expansion or shrink and and the engagement post paired engagement with it.
The sun that discloses in the clear 52-51242 of Japanese patent publication No. has identical structure with the surface fastener of former casting, the sun of this fastener and cloudy engaging element have the S shape curved surface perpendicular to the front surface extension of substrate usually, and each spherical engaging element has pod in its center of top.When the attaching parts of the sun of same structure and cloudy surface fastener are pushed toward each other because of engagement, elastic deformation radially inwardly takes place so that promote engaging element and the engaging element engagement of the surface fastener paired with it in the spherical part of the pod of each engaging element, and the time flexibly recover their original form immediately finishing engagement, thereby the engaging element that guarantees each engaging element unit and the surface fastener paired with it is along each other S shape curved surface tight engagement.
In the surface fastener of the die casting that in the flat 3-286702 of Japanese patent publication No., discloses, positive and cloudy surface fastener has identical structure, many engaging elements are configured to square formation on the substrate front surface, each engaging element has a post and a hemispherical engagement post that is opposed on the substrate front surface, and the upper end of this engagement post cross-over connection post also has the disk that its upper surface archwise protrudes.And many braking ridges are arranged in each ridge on the front surface of substrate and are arranged between two parties between the engaging element in the square formation.The height of braking ridge is such: when the engaging element engagement of engaging element and the surface fastener paired with it, each braking ridge is contacted with the top of engagement post accordingly.
Surface fastener according to the die casting that in clear 47-11770 of Japanese patent publication Nos. and clear 52-51242, discloses, because when each engaging element and the surface fastener engaging element paired engagement with it, the engagement post of local or whole and paired with it surface fastener of each engagement post interacts, make in radially inner direction generation elastic deformation, so can reach level and smooth engagement.Yet, at engaging element and after the engaging element of the surface fastener paired engagement with it, when surface fastener was applied peeling force, each engagement post was easy to make surface fastener throw off from the surface fastener paired with it easily in radially inward direction generation elastic deformation.
In the surface fastener of the die casting that in the flat 3-286702 of Japanese patent publication No., discloses, because the engagement post of each engaging element is in radially not deformation of inward direction, adjacent engaging element stops the engagement post of the surface fastener paired with it to enter, and therefore, they are difficult to engagement especially.In order to guarantee level and smooth engagement, increase the distance between the engaging element that is arranged on the substrate inevitably, this causes joggled strength to reduce.
So the die casting surface fastener that an object of the present invention is to realize being made by synthetic resin and have certain rigidity is by pushing and level and smooth engagement toward each other, and also provide the die casting surface fastener, use this fastener, engaging element does not just chatter once engagement, high joggled strength is arranged simultaneously, throw off so that prevent them.
According to the present invention, achieve the above object by synthetic resin molded surface fastener, this surface fastener comprises: substrate; Engaging element on many front surfaces that stand on substrate, each engaging element have post that rises from the front surface of substrate and the engagement post that forms continuously and flatly protrude from the post upper end in the post upper end, and engagement post can flatly be expanded and shrink; Also comprise many diameter amplifying devices, each device be used for engagement post respectively and the engagement post of the surface fastener paired when engagement with it enlarge the diameter of engagement post.
Best, engagement post is divided into two or more segments by a segmentation plane perpendicular to substrate surface at least, and each segment is spaced apart from each other with predetermined gap.In the case, if segmentation plane extends in the post.Just be enough to give engagement post expansion and the function of shrinking.Yet preferably segmentation plane extends to the front surface of substrate.By this structure, can promote the elastic bending of engagement post and column and can guarantee between engaging element, smoothly to mesh and guarantee an engagement post expansion and enough joggled strengths reliably by an enlarged-diameter device.
For a kind of preferable style, each enlarged-diameter device is the taper bulge, and this bulge is from substrate front surface protuberance, the center between the forward and backward and left and right adjacent engaging element that is arranged in the engaging element on the square formation.According to this style, when surface fastener pushes facing to the surface fastener paired with it, with preceding, after, a left side, the interactional engagement post of engagement post of right engaging element enter and the engaging element of the surface fastener that it is paired between, flexibly recover its original shape then, at the same time, each bulge enters between each segment of each engagement post, further at the bent fan body flexibly of direction radially outward, thereby increase the diameter of engagement post, make and the engagement post of the expansion of the surface fastener paired with it meshes and the sound and avoided disengagement reliably of not chattering securely.For the engagement between the engaging element that discharges two surface fasteners with desired peeling force, the global shape of each engagement post can change on demand.For example, the shape of engagement post protrusion can change over pure sphere by mushroom umbrella shape according to needed joggled strength.
For another preferable style, each enlarged-diameter device is included in a bridgeware between the segment top of engagement post, and the length between this bridgeware link is greater than the distance between the segment of engagement post.According to this style, when surface fastener pushes facing to the surface fastener paired with it, and the interactional engagement post of the engagement post of front, rear, left and right engaging element enters and the engaging element of the surface fastener that it is paired between, on diametric(al), shrink, flexibly recover its original form then, arch bridge fitting between the segment of each engagement post is extruded facing to the front surface of the substrate of the surface fastener paired with it simultaneously, because reaction force makes bridgeware elasticity become straight.At this moment by means of the bridge joint power of being discussed, segment is further in elastic bending radially outward, thereby increases the diameter of engagement post, therefore the engagement post of secure engagement and the surface fastener paired with it similarly.Do not chatter when in view of the above, their mesh and also can avoid reliably throwing off.For obtaining enough peel strengths between engaging element, the rigidity of bridgeware can be adjusted by changing die casting thickness.

Be described in detail exemplary embodiments of the present invention referring now to accompanying drawing.Fig. 1 is the incomplete perspective view according to the surface fastener of the die casting of first embodiment, and Fig. 2 is the sectional drawing of being got along the I-I line of Fig. 1, and Fig. 3 is the sectional drawing of being got along the II-II line of Fig. 2.
Reference number 1 indicates the surface fastener by the die casting of injection-mould casting method manufacturing with the thermoplastic synthetic resin material in Fig. 1 to Fig. 3.The thermoplastic synthetic resin material for example is independent and compound polyamide, mylar, acrylic resin, polyvinyl resin, polystyrene resin and polyurethane resin.For simplifying die casting method, die casting surface fastener of the present invention should have rational shape.
The integral body of the surface fastener 1 of die casting is made by identical type synthetic resin material.The surface fastener 1 of die casting comprises substrate 2, and is many in the engaging element 3 of lining up square formation on the front surface of substrate 2 and many bulges 4 of lining up square formation on substrate 2 front surfaces, the center of each bulge between front, rear, left and right engaging element 3.Though the height of bulge 4 can be by arbitrarily determining, but require to be: the engagement post 3b of the engaging element of narration is with before the engagement post 3b that cooperates meshes below just, and the core at the top of each bulge 4 stretches into each engagement post 3b with the surface fastener of the same structure of its pairing.Each engaging element 3 has the columniform hemispherical engagement post 3b that stands on the post 3a on the substrate front surface and flatly protrude from post 3a upper end.
From Fig. 1 to Fig. 3 obviously as can be known, the engaging element 3 of first embodiment comprises the pillar 3a ' of segmentation again, 3a ' is when the predetermined cross of horizontal section is divided into four segments at interval, form by division cylindrical pillars 3a, engaging element 3 also comprises a 3b ' of segmentation again, 3b ' is positioned at be that hemispherical engagement post 3b is divided into four segments and forms basically in the top of each pillar 3a ' that divides again.Like this, the divisional plane of engagement post 3b vertically extends on the front surface of substrate 2 by post 3a.The arcuate surfaces of the bottom of the pillar 3a ' that each divides is again surrounded by radial expansion and the scallop hole 2a that passes substrate 2.In addition, substrate 2 has many through hole 2b in the rear surface of substrate 2, and each through hole is positioned at the central authorities of the bottom of each post 3a, and each through hole 2b has circular cross section, and its diameter is than bigger with the tangent diameter of a circle of four interior angles that divide pillar 3a ' again.
Each bulge 4 that stretch out from the front surface of substrate 2 center between front, rear, left and right engaging element 3 is examples that constitute a diameter amplifying device of a significant element part of the present invention.In this graphic example, bulge 4 is moulded on the front surface of substrate 2 with substrate 2 and engaging element 3 simultaneously to be the hemisphere form usually.The another kind of selection, bulge 4 can be common taper.That is, as long as it has tapering towards its top, bulge 4 just can enlarge the diameter of the engagement post 3b of the surface fastener paired with it, and thus, it is inserted into enlarged footing 3b.
The scallop hole 2a ' that forms in substrate 2 and the 3b ' of parted hair again that forms on each divides pillar 3a ' again have common projection plane.The interface of supposing post 3a and engagement post 3b is separator bar P1 as shown in Figure 2, scallop hole 2a and divide again pillar 3a ' in the central through hole 2b that is formed centrally be needs as growth, it depends on the design of injection mould, and this is that the die casting expert can understand easily.
Referring now to Fig. 4 and the effect of Fig. 5 narration according to first embodiment of the present invention die casting surface fastener when extruding is connected.What Fig. 4 illustrated said structure is in aspectant relation being extruded preceding two die casting surface fasteners their engaging element 31 this moment toward each other.When two surface fasteners 1 were extruded from back side pressurization toward each other, each engaging element of a surface fastener 1 entered between the engaging element that is arranged in another surface fastener 1 on the square formation, contacts the spherical part of engagement post 3b simultaneously.At that time, because the engaging element 3 of a surface fastener 1 is to force to enter between the engaging element 3 of another surface fastener 1 simultaneously that engagement post 3b contacts with each other, so divide again under the mutual pressure of pillar 3a ' at branch engagement post 3b ' again 4 of each engaging element 3 on the surface fastener 1 and to curve inwardly, thereby reduced the whole diameter of engagement post 3b, so that the engagement post 3b of a surface fastener 1 can be entered between the engagement post of another surface fastener 1 smoothly.
Cross in the engagement post of each surface fastener 1 before the engagement post 3b of another surface fastener 1, in the middle of each bulge 4 that stretches out from the substrate of the surface fastener paired with it makes and and then inserts the engagement post of the branch again 3b ' of 4 gatherings from central authorities.Along with the continuation of engagement post 3b is inserted, the engagement post that surmounts the surface fastener paired with it, each bulge is advanced further, it is separated from one another flexibly to promote 4 engagement post 3b ' that divide again, be separated to the ultimate range that causes by bulge 4, so that make engagement post 3b can not have securely card take sound ground with and the engagement of the engagement post of its paired surface fastener 1, as shown in FIG. 5.As a result, the surface fastener 1 that can not separately firmly connect with limited peeling force.
In order to adjust peeling force, the shape of engagement post 3b can be revised.For example, in order to untie the surface fastener that has connected with limited peeling force, the lower surface of engagement post 3b can be the convex surface that protrudes downwards rather than horizontal plane with the plane because the radian of arcuate surfaces is variable, so peeling force can be adjusted.
Fig. 6 to Fig. 8 illustrates the modified of first embodiment.In this modified, except the through hole 2b of the substrate 2 of the bottom downside of post 3a was omitted, die casting surface fastener 1 was structurally the same substantially with first embodiment.Even without through hole 2b, also may enough reach purpose of the present invention and simplify the design of mould and the carrying out of die casting process, so just reduced the cost of design.
Fig. 9 to Figure 11 illustrates the surface fastener according to the die casting of second embodiment of the invention.Fig. 9 is the incomplete perspective view of the die casting fastener of second embodiment, and Figure 10 is the sectional drawing of being got along the III-III line of Fig. 9, and Figure 11 is the incomplete plane of the die casting surface fastener of second embodiment.Figure 12 is a sectional drawing, the die casting surface fastener that second embodiment is shown with the surface fastener engagement of its paired same structure.
The difference of this embodiment and first embodiment is an enlarged-diameter device of engagement post, and remainder keeps the basic structure similar to first embodiment of Fig. 1 to Fig. 3.Correspondingly, those parts that are similar to first embodiment and unit omit the enumeration to them here with identical reference numerals, concentrate a narration enlarged-diameter device.
Comprise with injection moulding process that according to the die casting surface fastener of this embodiment the substrate 20 of synthetic resin material monolithic die casting and each are had post 30a and engagement post 30b, and on the front surface of substrate 20, be arranged in many engaging elements 30 of square formation.In this embodiment, identical with first embodiment, each engaging element 30 comprises by four the upright post of branch again 30a ', four more separately 30b ' and bridgeware 40 constitute one overlap member, each has four/half bulb that radially protrudes from the upper end of dividing post 30a ' again more separately, and this bridgeware is extending between the top of 30b ' more separately.Divide post 30a ' again and separately 30b ' is structurally identical with among first embodiment those substantially again.
Bridgeware 40 is exemplary of enlarged-diameter device, and this device constitutes a part of significant element of the present invention.In this embodiment, figure out from Figure 10 and 11, bridgeware 40 is roughly the style of square plate, and Qi Sijiao is Unitarily molded, respectively with four more separately the upper end of 30b ' link to each other.In any case if bridgeware 40 links to each other with the top of parted hair 30b ' again with the dull and stereotyped style that is square substantially, then engagement post 30b can not enlarge on diametric(al).Therefore, in this embodiment, four edges of bridgeware 40 are aduncate, and the center of bridgeware 40 is protruding upward.
When the core 40a of the protrusion of bridgeware 40 was subjected to the top compressing to produce elastic deformation, it necessarily had by causing that to four jiaos of propagation pressures four are divided pillar 30a ' radially outward crooked function again, so as to make four more separately 30b ' be moved away from each other.For this purpose, bridgeware 40 needs enough rigidity, if with the material of determining, then can obtain such rigidity by the thickness of adjusting bridgeware 40.In this graphic example, bridgeware 40 has homogeneous thickness in its whole zone.On the other hand, the thickness of bridge 40 can change or have simple cross shape partly.Though the protrusion amount of the protrusion core 40a of bridgeware 40 can be provided with on request, but the aspect ratio of preferably dividing post 30a ' again comprises that the total height of engagement post 30b of protrusion amount of protrusion core 40a of bridgeware 40 is little, so as to make engaging element 30 with and the engaging element of its paired surface fastener do not have card securely and take sound ground and mesh.
Now the die casting surface fastener of narrating second embodiment with Figure 12 with and the mode of the surface fastener engagement of its paired same structure.
The surface fastener 10 pressurizeds engagement that Figure 12 is illustrated in two die castings of second embodiment time is in the engaging element 30 of engagement.When two surface fasteners 10 toward each other, pressurize from their back, and their mating surface is when facing each other, and each engaging element 30 of a surface fastener 10 enters between those engaging elements of lining up square formation of another surface fastener 10, contacts the arcuate surfaces of engagement post 30b simultaneously.At that time, because the engaging element 30 of a surface fastener 10 is suppressed between the engaging element 30 of another surface fastener 10, engagement post 30 contacts with each other again simultaneously, so divide again under the mutual pressure effect of post 30a ' at branch engagement post 30b ' again four of each engaging element 30 on the surface fastener 10 and to curve inwardly, and bridgeware 40 is also crooked, thereby has reduced the whole diameter of engagement post 30b.As a result, engagement post 30b can enter between those engagement post of another surface fastener 10 smoothly.
Between engaging element 30, continue to insert and surmount those engagement post of the surface fastener paired with it along with engagement post 30b, 30b ' flexibly recovers separately again, leave again each other, return to their original form, and the core 40a of the protrusion of each bridgeware 40 is pushed downwards owing to the front surface of the substrate of the surface fastener 10 paired with it at the same time, strain takes place and flattened in the core 40a that make to protrude, promote by reaction force simultaneously, four separately 30b ' is away from each other again, and then as shown in Figure 12, engagement post 30b can not have securely card take sound ground with and those engagement post engagement of its paired surface fastener.As a result, can not separate connected surface fastener 10 with limited peeling force.
In order to adjust peeling force, the shape of engagement post 30b is changed as first embodiment, or the thickness of the bridgeware 40 between parted hair 30b ' is provided with thinlyyer again.If use same material, the thickness of bridgeware 40 foot bridge fitting 40 more becomes flexible more.As a result, the surface fastener 10 of two die castings can be relatively easily with required peeling force separately.
The present invention never is defined in this graphic exemplary, and can propose various other modifieds.
As shown in the above description, according to die casting surface fastener of the present invention, at least in part because each engaging element 3,30 engagement post 3b, 30b can expand and shrink on diametric(al), thereby help engaging element 3,30 with and its paired surface fastener 1, those engaging element engagements of 10, partly because substrate 2,20 or each engagement post 3b, 30b has an enlarged-diameter device, this device and substrate 2,20 combine can play the expansion engagement post 3b paired with it on diametric(al), the effect of 30b, so when two the surface fastener of same structure pushes toward each other substantially, engagement post 3b, 30b head of a quilt enlarged-diameter device on diametric(al) enlarges and each engagement post 3b, and 30b keeps the expansion figure, make like this engaging element 3,30 with and the shockproof securely sound of the engaging element ground of its paired surface fastener mesh.
