Description

Die Erfindung betrifft einen Haftverschluß zur lösbaren Verbindung von Substraten, an denen flächige Verbindungselemente angeordnet sind, wobei Verbindungselemente mit über deren Oberfläche verteilten harten Verhakungsgliedern mit komplementären weichen Verhakungsgliedern (Schlaufenglieder) zusammenwirken und ein Verbindungselement beidseitig mit Verhakungsgliedern versehen ist.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.

Haftverschlüsse mit Bändern mit florartiger bzw. Floroberfläche, wobei die Oberfläche eines Bandes, die Verhakungselemente, wie einen Haken-oder Pilzflor, aufweist, mit der Oberfläche eines Bandes, die korrespondierende Schlaufenelemente aufweist, lösbar verhakbar ist, sind als sogenannte Klettbandverschlüsse, insbesondere am Textilsektor, weit verbreitet.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.

Derartige Haftverschlüsse und ihre Herstellung sind z.B. in der DE-PS 958 100 und in der DE-AS 1 535 803 beschrieben und werden in der Folge kurz als Velcro-Verschlüsse bezeichnet, wobei "Velcro" ein Warenzeichen ist.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.

In der Praxis besteht ein derartiger Verschluß ausschließlich aus einem sogenannten Hakenband oder Pilzband (Pilzkopfband), das einseitig Verhakungselemente aufweist, und einem sogenannten Florband (Flauschband, Velourband), das einseitig korrespondierende Schlaufenelemente aufweist. Die Verhakungselemente sind dabei aus thermoplastischen Kunststoffen hergestellt.In practice, 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.

Diese Thermoplaste erweichen bei Bügeltemperatur, so daß beim Bügeln eines Kleidungsstücks der Verschlußbereich nicht gebügelt werden darf, was an sich optisch ungünstig ist, da das Kleidungsstück dann immer einen ungebügelten Eindruck macht, aber häufig doch der Verschlußbereich unter Zerstörung der Haftwirkung gebügelt wird. Auch bei Kochtemperaturen ist Schädigung möglich, wobei Waschhinweise häufig übersehen werden. Diesen Velcro-Verschlüssen haften somit wesentliche Nachteile an.These 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.

In der DE-OS 2 256 626 ist ein besonderes Velcro-Verschlußsystem mit starren Verhakungselementen beschrieben, die mit den komplementären Verhakungselementen nur dann eine Verbindung zulassen, wenn stark zusammengedrückt wird. Dazu ist eine kompressible Polsterschicht vorgesehen, und korrespondierende Halteelemente können einander nur nach Zusammendrücken dieser Schicht erreichen. Es ist bei einer Ausführungsform angegeben, daß auf eine derartige Polsterschicht beidseitig ein Verhakungsband aufgebracht werden kann, wobei man einen flachen Gegenstand erhält, dessen beide Flächen die Möglichkeit zu einer Verhakung bieten. Es wurde dabei offenbar daran gedacht, entweder die eine oder die andere Seite zu benützen, was z.B. bei Abnützung der einen Seite möglich wäre. Die oben aufgezeigten Nachteile der bekannten Verschlüsse können auch durch diesen Verschluß nicht beseitigt werden.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. For this purpose, a compressible cushion layer is provided, and corresponding holding elements can only reach each other after this layer has been compressed. In one embodiment it is stated that 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.

In der EP-A 0 145 523 ist ein Haftverschluß zur Befestigung von Überzügen an Autositzen beschrieben. Hiezu ist ein Band vorgesehen, das an einer Seite Verhakungselemente und an der anderen Seite Verankerungselemente aufweist. In einer Spritzform wird das Band mit dem Schaumstoffkörper des Sitzes so verbunden, daß der eingespritzte Schaumstoff in die Zwischenräume zwischen den Verankerungselementen eindringt und derart nach dem Aushärten das Band mit dem Schaumstoffkörper unlösbar verbunden ist. Auf das Band kann dann lösbar ein mit Schlaufenelementen versehener Sitzüberzug aufgebracht werden. Ein derartiger Verschluß ist nur sehr beschränkt brauchbar, weil das Band und der Schaumstoffkörper fest miteinander verbunden sind, zur lösbaren Verbindung demnach nur die eine Seite des Bandes zur Verfügung steht.EP-A 0 145 523 describes an adhesive fastener for fastening covers to car seats. For this purpose, a band is provided which has hooking elements on one side and anchoring elements on the other side. In an injection mold, 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.

Es bestand somit die Aufgabe, einerseits die beschriebenen Nachteile zu vermeiden und andererseits Haftverschlüsse für verschiedene Anwendungsgebiete brauchbar zu machen. Derartige Bänder- bzw. Plattenkombinationen könnten nämlich nicht nur auf dem Textilsektor eingesetzt werden, sondern überall, wo Substrate temporär miteinander verbunden werden sollen, z.B. für Transport- oder Förderzwecke, oder wenn zwei Bänder in einer Behandlungsvorrichtung zeitweilig aneinander anliegend ohne gegenseitige Verschiebung bewegt werden sollen. Dabei wäre es günstig, wenn die mit Verbindungselementen versehenen Substrate als solche nicht aneinander oder an anderen Körpern haften, sondern erst im Bedarfsfall miteinander kraftschlüssig verbunden werden können.The task was therefore to avoid the disadvantages described on the one hand and to make adhesive fasteners usable for various fields of application on the other. Such belt or plate combinations could not only be used in the textile sector, but everywhere where substrates are to be temporarily connected, e.g. for transport or conveying purposes, or if two belts in a treatment device are to be moved temporarily against one another without mutual displacement. It would be advantageous if the substrates provided with connecting elements as such do not adhere to one another or to other bodies, but rather can only be connected to one another in a force-locking manner if necessary.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vor allem vorgeschlagen, daß der Verschluß aus drei Verbindungselementen gebildet ist, von denen zwei an jeweils verschiedenen Substraten angebracht und von mindestens einem, beidseitig von den beiden anderen Verbindungselementen lösbaren Mittelelement in Form eines Bandes oder einer Platte zusammengehalten sind.To achieve this object, it is proposed according to the invention in particular that 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.

Das mittlere Band oder die Platte ist dabei vorzugsweise unabhängig von den beiden anderen Bändern, so daß es entfernt werden kann; beispielsweise dann, wenn ein unbeabsichtigtes oder mißbräuchliches Verbinden der Substrate ausgeschlossen werden soll. Auf diese Weise ist es auch möglich, das mittlere Band oder Platte zum zeitweiligen Verbinden verschiedener Substratpaare heranzuziehen, beispielsweise verschiedener Formkörper, Namensbänder, Dekorationsgegenstände u.dgl. Auf dem textilen Sektor ist ein Beispiel das Vorsehen von einem Verschluß-Mittelband für mehrere Garnituren von beispielsweise Bettwäsche.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. In the textile sector, one example is the provision of a fastener center tape for several sets of, for example, bed linen.

Es kann auch günstig sein, z.B. bei nicht waschbaren Kleidungsstücken, das mittlere Band zumindest an einem Ende mit den beiden anderen Verschlußbändern zu verbinden. In einem Fall kann dadurch das Band nicht verloren gehen, der Verschlußbereich aber gebügelt werden, im anderen Fall ein Doppelverschluß mit bevorzugter Trennfläche ausgebildet werden.It 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. In one case 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.

Trennflächen mit verschiedenem Aufreißwiderstand können z.B. erzielt werden, wenn das mittlere Band oder die Platte beidseitig mit Verhakungsgliedem mit unterschiedlicher Anzahl und/oder Ausbildung der Verhakungsglieder je Oberfläche ausgebildet wird. Bei der Ausbildung kann z.B. die Höhe, Dicke und Länge, die Form und die Materialwahl variiert werden; es ist auch möglich, eine Oberfläche mit Haken und die andere mit Pilzen auszurüsten.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. During training, for example, 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.

Auf diese Weise wird erreicht, daß ein zentrales Hakenband beim gewöhnlichen Aufreißen des Verschlusses immer an einer Seite mit einem korrespondierenden Florband verbunden bleibt, von dem es anschließend abgerissen werden kann, wenn dies nötig erscheint.In this way it is achieved that a central hook band always remains connected on one side to a corresponding pile ribbon from which the closure can then be torn off if this appears necessary.

Mit dieser Anordnung lassen sich z.B. übereinander liegende Taschenfächer voneinander trennen, von denen im Normalfall nur eines geöffnet wird. Ein Diebstahl wäre dann auch bei geöffneter Tasche in aller Regel auf das geöffnete Fach beschränkt; das andere Fach stellt ein Sicherheitsfach dar.With this arrangement e.g. Separate stacked pocket compartments from each other, of which only one is normally opened. Theft would then generally be restricted to the opened compartment even with the bag open; the other compartment is a security compartment.

Bei Kleidungsstücken, die nicht gebügelt werden, ist dabei auch möglich, beide Enden der Bänder miteinander zu verbinden.For items of clothing that are not ironed, it is also possible to connect both ends of the straps together.

Ein weiterer Grundgedanke zur Anwendung des dreiteiligen Verschlusses besteht in der Möglichkeit, ein und dasselbe Objekt (Kleidungsstück etc.) damit so auszurüsten, daß es ohne jede weitere Bearbeitung entweder ständig geschlossen oder aber nach Entfernung des Mittelbands ständig geöffnet bleibt und anders als durch Veränderung (Bearbeitung wie Nähen etc.) oder Einsetzen des Doppelbandes auch nicht wieder verschlossen werden kann bzw. umgekehrt.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.

Der erfindungsgemäße Haftverschluß mit Mittelband kann insbesondere auf dem textilen Sektor überall dort mit Vorteil eingesetzt werden, wo die Anwendung des herkömmlichen, 2-lagigen Haftverschlusses entweder ausgeschlossen oder mit Nachteilen verbunden ist. Z.B. sind für den herkömmlichen Haftverschluß alle Anwendungen ausgeschlossen, bei denen der Verschluß höheren Temperaturen ausgesetzt ist, oder wo eine Kombination von Druck und höheren Temperaturen ausgeübt wird.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.

Weiterhin sind alle Anwendungen nur sehr bedingt möglich, bei denen ein oder beide Trägerstoff(e) eine velourartige, flauschartige, gestrickte, gehäkelte oder sonstige maschenartige oder sehr empfindliche Oberfläche aufweisen. Der Grund dafür ist ein ständiges Verhaken der harten Verhakungselemente - vor allem in geöffnetem Zustand - mit den Trägerstoffen. Dies ergibt zumindest lästige Störungen (z.B. beim Aus- und Anziehen von Kleidungsstücken), oftmals aber auch Beschädigungen bis Zerstörungen an den Trägerstoffen selbst oder - beim Waschen oder Reinigen - an anderen Kleidungsstücken.Furthermore, all applications are only possible to a very limited extent in which one or both carrier material (s) have a velor-like, fluffy, knitted, crocheted or other mesh-like or very sensitive surface. The reason for this is the permanent interlocking of the hard interlocking elements - especially in the open state - with the carrier materials. This results in at least annoying disturbances (e.g. when taking off and putting on clothes), but often also leads to damage or destruction on the carrier materials themselves or - when washing or cleaning - on other items of clothing.

Alle diese Nachteile können mit dem erfindungsgemäßen Haftverschluß einfach ausgeschaltet werden, der auch in Bereichen, die durch den herkömmlichen Haftverschluß aus funktionellen Gründen nicht abgedeckt werden können, voll einsetzbar ist, z.B. in Anwendungsbereichen, bei denen es vorteilhaft ist, ohne nochmalige Bearbeitung die Haftkräfte zu verändern. Dies kann beispielsweise durch seitenverkehrtes Wiedereinsetzen des Mitteibandes mit unterschiedlichen Aufreißwiderständen pro Oberfläche oder durch Herausnehmen des ursprünglich eingesetzten Mittelbandes und Austauschen gegen ein Mittelband mit anderen (größeren oder kleineren) Haftkräften erfolgen, was z.B. ein versuchsweises Ermitteln der idealen Haftkräfte bei Neuentwicklungen etc. bzw. ebenfalls auch Korrigieren einmal gewählter Haftkräfte ermöglicht.All of these disadvantages can be easily eliminated with the adhesive fastener according to the invention, which 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.

Im Rahmen der Erfindung liegen auch Anwendungsbereiche, in denen ein Nähen, Kleben oder sonstiges Aufbringen von Haftbändern (hart und weich) nicht möglich oder nicht erwünscht ist, aber trotzdem Oberflächen, die selbst Verhakungsmittel aufweisen, miteinander verbunden werden sollen, z.B. bei der Befestigung von Polstern aneinander. Die beiden äußeren Verbindungselemente werden dann von den Oberflächen der Substrate selbst gebildet.Within the scope of the invention there are also areas of application in which sewing, gluing or other application of adhesive tapes (hard and soft) is not possible or undesirable, but nevertheless surfaces which themselves have hooking means are to be connected to one another, e.g. when attaching cushions to each other. The two outer connecting elements are then formed by the surfaces of the substrates themselves.

Es ist auch der Einbau von "Solltrennstellen" (auch mit unterschiedlichen Haftkräften insgesamt oder pro Oberfläche) in Arbeitsbekleidungen, die der Sicherheit dienen, möglich:

  • Z.B. "Abreißärmel" bei Gefahr des Einwickeins, Hängenbleibens, etc.,
  • "Abreißschürze" bei Gefahr des Einwickeins, Hängenbleibens, etc.
It is also possible to install "predetermined separation points" (also with different adhesive forces in total or per surface) in work clothing that serves safety:
  • Eg "tear-off sleeves" if there is a risk of being wrapped up, getting caught, etc.,
  • "Tear-off apron" if there is a danger of being wrapped up, getting caught, etc.

Besondere wirtschaftliche Vorteile ergeben sich bei einem Bettwäscheverschluß: Große Vorteile liegen einerseits im sparsamen Einsatz des Mitteibandes (Haken oder Pilz) - man benötigt pro Kissen oder Tuchent nur ein Stück - und andererseits in der enormen Vereinfachung des Handlings (Öffnen, Verschließen) gegenüber allen üblichen Verschließmöglichkeiten; Reperaturen kommen nicht vor. Die Velour-Außenbänder sind ohne Mehraufwand bei der Herstellung des Überzuges anzunähen. Bei Verlust des Mittelbandes ist eine einfache Ergänzung von der Vorratsrolle möglich. Ein besonders vorteilhafter Einsatz des 3-Band-Haftverschlusses ergibt sich in Krankenhäusern, Anstalten, Heimen, Hotels etc., wo die Arbeitszeit ein erheblicher Kostenfaktor ist.There are particular economic advantages with a bedding lock: Great advantages are the economical use of the middle band (hook or mushroom) - you only need one piece per pillow or towel - and the enormous simplification of handling (opening, closing) compared to all the usual ones Locking options; There are no repairs. The velor outer tapes can be sewn on without additional effort when producing the cover. If the medium band is lost, it is easy to add to the supply roll. A particularly advantageous use of the 3-band adhesive closure results in hospitals, institutions, homes, hotels etc., where working hours are a considerable cost factor.

Bei der Konfektion von Arbeits- und Arbeitsschutzbekleidung kann der 3-Band-Haftverschluß ohne Mehraufwand eingearbeitet werden. Wirtschaftliche Vorteile sind hier durch funktionelle Vorteile, eventuell auch durch Sicherheitsvorteile (Schnellabtrennung eines Kleidungsteiles bei Überschreiten einer bestimmten vorgewählten Haftkraft) zu erwarten.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).

    • one surface has higher hooks (or mushrooms), another surface has lower hooks (or mushrooms),
    • one surface denser, the other surface less dense arrangement of identical or unevenly shaped hooks or mushrooms.

Alle obigen Kriterien können sowohl bei den Seitenbändern als auch beim Mittelband kombiniert werden. Eine besonders einfache Kombination ist ein Mittelband mit beidseitig gleicher Oberflächenausbildung und zwei verschiedene Seitenbänder. Ebenso können auch zwei gleiche Seitenbänder mit einem Mittelband kombiniert werden, das ungleiche Oberflächenausbildung aufweist, z.B. andere oder mehr Verhakungsmittel auf einer Seite. Dann muß das Mittelband aber gezielt seitenrichtig eingesetzt werden. Die Anordnung der Verhakungsmittel auf den Seitenbändern und dem Mittelband kann bezüglich einer Variation von deren Dichte beispielweise so erfolgen, daß verhakungsmittelfreie Zonen vorliegen, die Bänder somit z.B. in Längs- und/oder Querrichtung unterteilt sind, wobei vorzugsweise die Verhakungszonen dann gleich ausgebildet sind, so daß die unterschiedliche Haftkraft nur eine Funktion der haftenden Fläche ist. Unter Dichte der Verhakungsmittel wird im allgemeinen deren Anzahl bezogen auf jeweils eine Gesamtseite eines Bandes verstanden, mit der obigen Maßgabe, daß keine gleichmäßige Verteilung vorliegen muß.All of the above criteria can be combined for both the sidebands and the midband. A particularly simple combination is a central belt with the same surface formation on both sides and two different side belts. Likewise, 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. Then 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.

In an sich bekannter Weise kann die erfindungsgemäße 3-Elementkombination auch längs- und/oder quer-elastische Bänder aufweisen; als Mittelband können auch "Rücken an Rücken" aneinandergefügte, einseitig Verhakungsmittel aufweisende, Bänder eingesetzt werden. Auf diese Weise sind insbesondere Mittelbänder mit verschiedenen Seiten sehr einfach herstellbar; auch gleichartige Bänder können zusammengefügt oder einfach der Länge nach gefaltet und z.B. verklebt oder vernäht werden.In a manner known per se, 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. In this way, in particular, 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.

Die erfindungsgemäße 3-Elementkombination kann auch in entsprechender Vervielfachung angeordnet werden, z.B. zum reihenweisen Verbinden von Substraten. Wesentlich ist dabei das funktionelle Zusammenwirken über jeweils ein Mittelelement, d.h. die Kombination ABA bzw. BAB anstelle von wie bisher AB. Dabei ist auch der Einsatz mehrerer Mittelelemente pro Kombination möglich, so z.B. bei einem breiten Verschluß mehrere schmale Mittelelemente nebeneinander.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.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles unter Bezugnahme auf die Zeichnung näher erläutert, in der Fig. ein Mittelelement und Fig. 2 das Zusammenwirken des Mittelelementes nach Fig. I mit korrespondierenden Seitenelementen zeigt.The invention is explained in more detail below using an exemplary embodiment with reference to the drawing, in which FIG. 1 shows a central element and FIG. 2 shows the interaction of the central element according to FIG. I with corresponding side elements.

Fig. 1 zeigt ein bandförmiges Substrat 1, das an einer Seite einen Hakenflor 1a und an der anderen Seite einen Pilzflor 1 b aufweist. Dieses Mittelband 1 korrespondiert nach Fig. 2 mit zwei gleichartigen Seitenbändern 2, die einseitig einen Schlaufenflor 2a tragen, in den jeweils der Hakenflor 1a bzw. der Pilzflor 1b eingreifen. Beim Trennen der Bänder wird zuerst das Seitenband abgelöst, das mit dem Hakenflor 1a korrespondiert, da die Haftkraft zwischen Pilzflor 1 und Schlaufenflor 2a höher liegt als die zwischen Hakenflor 1a und Schlaufenflor 2a; mit anderen Worten weist die dargestellte Verbindungselementkombination eine bevorzugte Trennfläche auf.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. When the tapes are separated, the side tape which corresponds to the hook pile 1a is first removed, since the adhesive force between the mushroom pile 1 and the loop pile 2a is higher than that between the hook pile 1a and the loop pile 2a; in other words, the connection element combination shown has a preferred separating surface.

Claims (6)

1. An adhesion connector for the releasable connection of substrates which comprises flat connecting elements (1, 2) formed over their surfaces with surface arrays of attachment members in a multiply complementary configuration with the attachment members on one of the elements (1) being formed with relatively hard hook-members (1a, 1b) while the attachment members on the other element are formed with complementary soft-hook engagement structures (loop members), one connecting element (1) has on each of two opposite sides attachment members (1 a, 1 b), characterized in that the adhesion closure comprises three connection elements of which two (2) are connected to different substrates, an intermediate connecting element (1) is removable insertable between the first two and in the form of a band or a plate.
2. The adhesion connector defined in claim 1 characterized in that said intermediate strip (1) or plate is formed on opposite sides with relatively hard-hook members (1 a, 1 b), the formations engageable by said hard-hook members being constituted as loop members (2a) on two strips (2) or plats.
3. The adhesion connector defined in claim 1 or 2 characterized in that separations with different pealing resistances can be generated by providing the surfaces of the strip (1) or plates with different attachment members (1 a, 1 b) on opposite sides thereof.
4. The adhesion connector defined in claim 3 characterized in that the hard-hook members on one side of said intermediate strip are simple hooks (1 a) and the hard-hook members on the opposite side of said intermediate strip are mushroom heads (1b).
5. The adhesion connector defined in one of the preceding claims characterized in that the strips (1, 2) or plates are attached together at at least one end thereof.
6. The adhesion connector defined in one of the preceding claims characterized in that the attachment members (1 a, 1 b) of the strips (1) or plates are nonuniformly distributed thereover, in particular the attachment members are provided in a strip pattern.
