Description

closing part

The invention relates to a closure part, in particular for the formation of her ^¬ maphroditischer closures.

As a component of adhesive closures, as they have become widely known under the trade designation "barnacles", such closure components have a corresponding plurality of locking bodies, which Verha- at one form the supporting structure are ^¬ set the basic body kung body at the end region of their stalks, in which The closure bodies are distributed in an arrangement in such a way that the hooking heads projecting above the base body are arranged at such distances from one another that an interlocking engagement with the hooking heads of the adhesive fastener vervollständigenden wide ^¬ ren closure part takes place. If the hook-up heads of the two mutually cooperating locking parts are formed identical, one speaks of hermaphroditic closures.

In a closure part of this type known from DE 10 2005 048 215 A1, two closure bodies each form a cramped or U-shaped pair, in which two stems are integrally connected to one another at their foot sides via a transverse intermediate element. The attachment to the body is made by the stems of each pair of the Rear side of the base body are inserted through openings in the base body, wherein the transverse intermediate element can be recessed at the back of the body in a recess extending between the openings.

On a closure part known from US Pat. No. 5,799,378, mutually parallel walls are arranged in a grid structure in two sets, wherein the sets of walls intersect at right angles. Interlocking heads of closure bodies are arranged at the intersections of the walls. The mushroom-shaped interlocking heads may be formed integrally with the walls, preferably of a plastic material. The spacings or sections between the walls are selected such that when a second closure part abuts, its interlocking heads engage in the respective free spaces of the lattice structure and catch in the lattice structure by engaging the hooking heads of the first closure part.

From DE 60 2004 007 373 T2 woven closure products with improved flame resistance properties have become known. A woven closure product includes a loop component and a hook component designed to engage the loop component. The components each include a plurality of loops which are woven into a fabric base. The fabric base includes woven, flame resistant fibers of a polymer that melts or dissolves when exposed to a flame.

DE 693 19 608 T2 discloses an interlocking fastening element which is advantageously used for fastening a window to a window frame of a motor vehicle. The fastener comprises a base part and a plurality of the base part projecting and longitudinal to parallel parallel Eingreifstreifen on. The engaging strips each have a vertical part adjacent to the base part, a head part adjacent to the vertical part, and two end faces. The engaging strips are adapted for engagement with a projecting head portion of an overall genüberliegenden fastener, wherein the head portion of the engaging strips has a plurality of transverse slits and the vertical parts remain slotted un ^¬. The transverse slots to facilitate sliding engagement of the fastening elements Be ^¬ with an opposing fastener.

It is the object of the invention to provide a closure part of the type under consideration, which is distinguished by particularly good service properties.

According to the invention this object is achieved by a closure part having the features of claim 1 in its entirety. The closure part according to the invention, in particular for the formation of hermaphroditic closures, is characterized by at least one carrier strip running in the form of a web, which has at least a pair of oppositely arranged surface regions which can be connected at least partially along a connecting region to a base body as a third component, and which at least in part Area regions that lie outside the connection area and adjacent to this, individual closure body has that form from the carrier tape projecting a fixing possibility for more closure parts of the same or different kind.

Accordingly, a significant feature of the invention is that the closure body are connected by a carrier tape at a distance from each other, which is substantially parallel to the respective closure body and not transverse thereto as in known solutions, in which the Stem of the respective closure body in a vertical arrangement merges into a carrier surface and is usually an integral part of the same.

The presence of a mechanical connection of the closure body via a carrier tape makes it possible, by selecting the dimensioning and the material properties of the band (rigidity) to set the structural properties of the closure part to a desired optimum, which results in the desired entangling forces. A special, further advantage is that in the production as a precursor arbitrarily large tape lengths can be made with it closure bodies, so that desired tape lengths can be divided and, for example, fed to a loading magazine, from which a basic body, such as a horizontally extending support surface, is equipped.

Preferably, the arrangement is such that the respective closure body has a hooking head and / or a handle adjoining the hooking head, and that the carrier tape is in contact with the respective closure body such that at least parts of the handle and / or the hooking head are in flat connection with the surface areas of the carrier tape are. This thus forms a web with it laterally adjacent, lined up to a chain closure bodies, preferably both surface parts of Verhakungskopfes and the stem are in areal connection with the carrier tape.

In a particularly advantageous manner, it can be provided here that the hooking head and / or handle are in area-related connection with the carrier tape over their entire axial extent, which is related to the longitudinal axis of the handle. With regard to the connection of the hooking bodies to the base body, it may be provided that the carrier tape protrudes beyond the end of the stalks of the hooking bodies away from the hooking head, in order to form an anchoring strip in the connecting area which can be fixed in an anchoring groove of a base body forming the supporting structure of the fastener part ,

Alternatively it can be provided that the carrier tape ends in front of the end of the stem of Verhakungskopf the hooking body, so that the projecting end portions of the stems form anchoring mandrels, which can be fixed in record-forming recesses of the support structure of the closure member forming body.

In particularly advantageous embodiments, the arrangement is such that in each case two closure bodies which lie flush on one side and the other side of the extending between them carrier tape together, together form a composite closure element. Such a composite closure element can be formed by two identically formed closure bodies each, wherein preferably rows of equidistantly spaced, assembled closure elements are formed on the carrier band.

Alternatively, however, the arrangement can also be made such that on each side and the other side of the carrier tape a row of equally spaced closure bodies is formed, wherein the rows are offset from each other such that the closure body of a row each in the space between the closing bodies of the other row. The invention further comprises a closure having at least one closure part according to the invention and a main body connected to the connection region of the at least one carrier tape. In order to form a regular pattern of closure bodies on the closure part, in this case, mutually parallel anchoring grooves for successive groups of carrier tapes can be provided in the base body at the same distance. Again, the recesses in the base body are preferably formed in spaced parallel rows.

The invention with reference to exemplary embodiments illustrated in the drawing is explained in detail.

The invention is explained below with reference to exemplary embodiments in which the closure parts are part of a hermaphroditic process. Conclude form, with closure body, the in Fig.! 2 as a whole, at the upper end of their stems 4 each have a Verhakungskopf 6 in the form of a majority of a mushroom head, which is delimited by a circular arc-shaped outline 8 and a flat top surface 10 extending along the longitudinal axis of the stem 4 in a plane Stem surface 12 continues. The stem surface 12 surrounds on the stem 4 in each case one of a part of a circular cylinder corresponding lateral surface 14th

It is understood that instead of the shown mushroom head shape of the interlocking heads 6 with a circular arc-shaped outline 8 for the Verhakungsköpfe a deviating from the circular outline, for example, polygonal shape, could be provided or another deviating from the mushroom shape design. Likewise, could be provided for the stems 4 deviates from the circular shape design of the outline.

FIG. 2 shows a composite closure element 18 formed by the combination of two closure bodies 2 with a carrier band 16. FIG. 3 shows the arrangement of four composite closure elements 18 on a respective, continuous, flat carrier band 16, with three rows in FIG composite closure elements 18 are formed, which form a portion of a closure part. As is also shown in FIG. 2, the respective closure bodies 2 rest against the entire surface on one side and the other side of the carrier tape 16, with their camming surface 10 and with their stem surface 12, in alignment with one another. The lower end portion 22 of the carrier tape 16 extends beyond the lower end 20 of the stems 4, so that this end portion 22 forms an anchoring bar, by means of which the rows of closure elements 18 can be anchored to a supporting structure, with reference to the Fig.6 below is. The closure part has, as shown in FIGS. 3, 4, 5, 7 and 9, one or more web-like carrier tapes 16, each with a pair of oppositely arranged surface regions 17a, 17b. The oppositely arranged surface regions 17a, 17b adjoin a connecting region 19, in this case the underside of the respective carrier strip 16. In other words, the surface areas 17a, 17b forming the side surfaces of the respective carrier tape 16 are arranged directly adjacent to the respective connection area 19. The connecting region 19 may also extend over a lower portion of the respective carrier tape 1 6. At the surface areas 1 7a, 17b, individual closure bodies 2 project from the respective carrier band 16, wherein the hooks 24 provided on the closure elements 18 form a fixing possibility for further closure parts of the same or different types. The closure bodies 2 or closure elements 18 designed from interlocking heads 6 and / or stems 4 lie flat against the respective carrier band 16 on the surface regions 17a, 17b and are thus held in a stationary manner on the latter.

In the production of separate closure body 2, as shown in Figure 1 by itself, be prepared by a suitable molding process of a plastic material or metallic material and connected to the carrier tape 16, for example by gluing. Alternatively, lengths of the carrier tape 16 with composite closure elements 18 formed from two closure bodies 2 can be formed integrally by means of a known production method, using techniques as shown, for example, in EP 1 047 539 B1 or DE 10 2004 012 067 A1 can. Suitable materials are plastics, such as polypropylene or polyamide or materials from the group of acrylates, such as polymethacrylate, as well as polyethylene, polypropylene, polyoxymethylene, polyvinylidene fluoride, polymethylpenthene, polyethylene chlorotrifluoroethylene, polyvinyl chloride, polyethylene oxide, polyethylene thylentheraphthalate, polybutylene teraphthalate, nylon 6, nylon 66 and polybutin. In the case of crosslinkable plastic materials, these can be post-crosslinked with UV light, for example, after the closure elements 18 have been produced. Thermoplastic see materials and those which are suitable for a thermosetting prove to be particularly suitable. It is also possible to use aramid, PPS (polypropylene sulfites) or aromatic polyether ketones, for example PEEK.

Figures 4 and 5 illustrate the Verhakungseingriff between two hermaphroditischen a closure forming closure parts according to the invention, wherein the connection of the respective end portions 22 of the carrier tapes 16 is not shown. As can be seen particularly clearly from Flg. 4, the retaining force is formed by the interaction of the planar interlocking surfaces 24 on the interlocking heads 6, whereby due to the planar contact high holding forces can be realized while the joining of the closure parts to form the Verhakungseingriffs a lower force requires because the rounded outer surfaces of the heads 6 are overflowed.

In FIG. 5, which illustrates the interlocking intervention, the interlocking surfaces 24 and the remaining structural elements are only partially numbered for the sake of clarity.

As already mentioned, the support structure is not shown in Figure 2 to 5, on which the closure elements 18 are fixed by means of anchoring bars, which are formed by the end portions 22 of the carrier bands 16 which project beyond the lower ends 20 of the stems 4. 6 shows a corresponding support structure in the form of a base body 26 in a plate-like form made of a plastic material that is readily formable by spraying. As receptacles for the anchoring strips formed by the end sections 22 of the carrier strips 16, anchoring grooves 28 with rectangular sections are provided in the main body 26. formed shaped channel cross-section. The determination of the end portions 22 in the anchoring grooves 28 can be done by gluing. Preferably, in the production, the procedure is such that the respective base bodies 26 are stocked from an assembly magazine, in which prefabricated lengths of the carrier strips 16 are provided with closure elements 18 thereon, and high production speeds can be achieved.

FIG. 7 illustrates a modified exemplary embodiment in which the top surfaces 10 of the interlocking heads 6 are in full contact with the carrier strip 16, the free ends 20 of the stems 4 extend beyond the end edge of the carrier strips 6. Adjacent to the ends 20, therefore, form the stems 4 on the carrier tape 16 projecting anchoring mandrels, in the present embodiment circular mandrels, for their absorption in the base body 26 shown in Figure 8 recesses 30 are formed in the form of circular cylindrical blind holes. Again, the determination can be made by gluing, with a mechanical loading of the body 26 also allows high production rates.

It is understood that instead of a circular cylindrical shape circumscribing stems 4 out of round or polygonal stems could be provided, the shape of the recesses 30 would be adjusted accordingly.

In the preceding exemplary embodiments, closure elements 18 assembled on the carrier band 16 are formed by arranging in each case a closure body 2 in alignment with both sides of the carrier band 16. 9 shows a modified example in which the closure bodies 2 on one side of the carrier tape 16 no closure body 2 opposite to the opposite side of the carrier tape 16 in alignment. Rather, in this case rows of individual closure bodies 2 are formed on each side, wherein the rows to each other are offset so that the closure body 2 of a number are each centrally located between two closure bodies 2 of the other row and so to speak, an alternating row of closure bodies 2 is formed, wherein instead of composite closure elements 18, each with two hooking heads 6 only one closure body 2 with a Verhakungskopf 6 effective Verhakungsflächen 24 forms on its underside. Again, to form hermaphroditic closures, a similar configuration may be provided on the associated closure member provided for the interlocking engagement. Corresponding exemplary embodiments are characterized by smaller forces required for effecting the hooking engagement, however, depending on the design of the interlocking heads 6, smaller holding forces can be realized, so that such closures can be formed such that opening of the closure is possible without too much effort is possible.

Starting from the illustration according to FIG. 9, it is also clear that a single closure body 2 can only consist of one interlocking head 6 with the proviso that the individual stems 4 are omitted and the respective interlocking head 6 is then connected directly to the carrier tape 16, which then as far as the individual stems replaced. In this way, even in a stepped arrangement, the interlocking heads 6 in different horizontal planes, based on the vertically oriented carrier tape 16, could be arranged thereon. As already stated, the entire closure part, consisting of the individual closure bodies 2, can be obtained with the carrier tape 16 by a shaping process. However, it is also possible first to produce the carrier tape 16 in isolation from the other closure part and to insert it, for example, as shown in FIG. 1 into the gap between two adjacent closure bodies 2 and to glue the corresponding closure body halves adhesively to the flat carrier tape, for example connect. The closure systems described can be designed as a single-use closure system or, as stated, as so-called closure systems that can be revealed and closed again and again. In any case, a longitudinal stiffening is brought about by the respective carrier band 16 between the closure bodies 2 in such a way that the closure elements with a corresponding construction are securely held in their locking position, so that in this respect the release forces are increased in this way. If required, further carrier tapes can intervene in rows in a manner not shown in detail between the carrier tapes shown, so that in this respect a box-like structure is created for the overall closure system. In that regard, a non-illustrated, square outer peripheral frame around the longitudinal rows of carrier bands 16 can be arranged.
