Definitions

  • the invention relates to an adhesive fastener for releasably connecting substrates on which flat connecting elements are arranged, connecting elements with hard interlocking members distributed over their surface interacting with complementary soft interlocking members (loop members) and a connecting element being provided on both sides with interlocking members.
  • Adhesive fasteners with tapes with a pile-like or pile surface, the surface of a tape having hooking elements, such as a hook or mushroom pile, being releasably hookable to the surface of a tape, which has corresponding loop elements, are known as Velcro tape closures, particularly in the textile sector , widespread.
  • Velcro closures Such fasteners and their manufacture are e.g. described in DE-PS 958 100 and in DE-AS 1 535 803 and are hereinafter referred to briefly as Velcro closures, "Velcro" being a trademark.
  • such a closure consists exclusively of a so-called hook band or mushroom band (mushroom head band), which has hooking elements on one side, and a so-called pile band (fleece band, velor band), which has corresponding loop elements on one side.
  • the interlocking elements are made of thermoplastic materials.
  • thermoplastics soften at the ironing temperature, so that the closure area must not be ironed when ironing a garment, which is optically unfavorable since the garment then always makes an un-ironed impression, but often the closure area is ironed while destroying the adhesive effect. Damage is also possible at cooking temperatures, although washing instructions are often overlooked. These Velcro closures therefore have significant disadvantages.
  • DE-OS 2 256 626 describes a special Velcro closure system with rigid interlocking elements which only allow a connection with the complementary interlocking elements when it is strongly compressed.
  • a compressible cushion layer is provided, and corresponding holding elements can only reach each other after this layer has been compressed.
  • a hooking tape can be applied to both sides of such a cushion layer, whereby a flat object is obtained, the two surfaces of which offer the possibility of hooking. It was obviously thought of using either one side or the other, which e.g. would be possible if one side wears out.
  • the above-mentioned disadvantages of the known closures cannot be eliminated by this closure either.
  • EP-A 0 145 523 describes an adhesive fastener for fastening covers to car seats.
  • a band is provided which has hooking elements on one side and anchoring elements on the other side.
  • the tape is connected to the foam body of the seat in such a way that the injected foam penetrates into the spaces between the anchoring elements and, after curing, the tape is inextricably linked to the foam body.
  • a seat cover provided with loop elements can then be releasably applied to the belt.
  • Such a closure can only be used to a very limited extent because the band and the foam body are firmly connected to one another, so that only one side of the band is available for detachable connection.
  • the closure is formed from three connecting elements, two of which are attached to different substrates and held together by at least one central element in the form of a band or a plate that can be detached from the two other connecting elements on both sides.
  • the middle band or plate is preferably independent of the other two bands, so that it can be removed; for example, if an unintentional or improper connection of the substrates is to be excluded. In this way, it is also possible to use the middle band or plate for temporarily connecting different pairs of substrates, for example different moldings, name bands, decorative objects and the like.
  • a fastener center tape for several sets of, for example, bed linen.
  • the middle band can also be inexpensive, e.g. in the case of non-washable garments, connect the middle band to the other two fastener tapes at least at one end.
  • the tape cannot be lost, but the closure area can be ironed, in the other case a double closure with a preferred separating surface can be formed.
  • Partitions with different tear resistance can be achieved, for example, if the middle band or the plate on both sides with interlocking members with different numbers and / or designs formation of the interlocking members is formed per surface.
  • the height, thickness and length, the shape and the choice of materials can be varied; it is also possible to equip one surface with hooks and the other with mushrooms.
  • Another basic idea for using the three-part fastener is the ability to equip one and the same object (clothing, etc.) so that it either remains closed without any further processing or remains open after removing the mid-band and other than by changing ( Processing such as sewing etc.) or inserting the double band can not be closed again or vice versa.
  • the adhesive fastener with a middle band according to the invention can be used with advantage in particular in the textile sector wherever the use of the conventional two-layer adhesive fastener is either excluded or associated with disadvantages. E.g. All applications in which the closure is exposed to higher temperatures or where a combination of pressure and higher temperatures is applied are excluded for the conventional adhesive closure.
  • the adhesive fastener according to the invention can also be used fully in areas which cannot be covered by the conventional adhesive fastener for functional reasons, e.g. in areas of application in which it is advantageous to change the adhesive forces without further processing.
  • This can be done, for example, by reversing the middle belt with different tear resistance per surface or by removing the originally used middle belt and exchanging it for a middle belt with different (larger or smaller) adhesive forces, which e.g. an experimental determination of the ideal adhesive force for new developments etc. or also the correction of selected adhesive forces is possible.
  • the 3-band fastener When assembling work and protective clothing, the 3-band fastener can be incorporated without additional effort. Economic advantages are to be expected here through functional advantages, possibly also through safety advantages (quick detachment of a piece of clothing when a certain preselected adhesive force is exceeded).
  • a particularly simple combination is a central belt with the same surface formation on both sides and two different side belts.
  • two identical side bands can also be combined with a central band that has an uneven surface formation, e.g. other or more hooks on one side.
  • the middle band must be used in the right direction.
  • the arrangement of the hooking means on the side bands and the middle band can be done with respect to a variation in their density, for example, so that there are zones free of hooking means, the bands thus e.g. are subdivided in the longitudinal and / or transverse direction, the hooking zones then preferably having the same design, so that the different adhesive force is only a function of the adhesive surface.
  • Density of the interlocking means is generally understood to mean their number, based in each case on an entire side of a band, with the proviso that there is no need for an even distribution.
  • the 3-element combination according to the invention can also have longitudinal and / or transverse elastic bands; "Back to back" tapes which are joined together and have hooking means on one side can also be used as the center tape.
  • middle bands with different sides can be produced very easily; similar tapes can also be joined together or simply folded lengthways and e.g. glued or sewn.
  • the 3-element combination according to the invention can also be arranged in a corresponding multiplication, e.g. for connecting substrates in rows. What is essential here is the functional interaction via a central element, i.e. the combination ABA or BAB instead of AB as before. It is also possible to use several middle elements per combination, e.g. with a wide closure, several narrow middle elements side by side.
  • FIG. 1 shows a central element
  • FIG. 2 shows the interaction of the central element according to FIG. I with corresponding side elements.
  • Fig. 1 shows a ribbon-shaped substrate 1 which has a hook pile 1a on one side and a mushroom pile 1 b on the other side.
  • 2 corresponds to two side bands 2 of the same type, which have a loop web 2a on one side, in which the hook web 1a and the mushroom web 1b respectively engage.
  • the connection element combination shown has a preferred separating surface.
