Description

Die Erfindung betrifft eine Leuchte gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a luminaire according to the preamble of claim 1.

Eine Leuchte dieser Art ist mit einem aus zwei Teilen bestehenden Gehäuse ausgebildet, von denen der eine Teil ein wannenförmiges Gehäuse ist, das Befestigungselemente zum Befestigen an einem Träger, z. B. einer Wand oder einer Decke, aufweist, und der andere Teil durch eine wenigstens teilweise transparente Abdeckung gebildet ist, die durch Verschlußelemente mit dem wannenförmigen Gehäuse lösbar verbunden ist. In dem durch das wannenförmige Gehäuse und die Abdeckung gebildeten Leuchtengehäuse ist eine Lampe mechanisch und elektrisch anschließbar , deren im Betrieb abgestrahltes Licht durch die transparente Abdeckung zur Raumbeleuchtung abstrahlt.A lamp of this type is formed with a two-part housing, of which one part is a trough-shaped housing, the fastening elements for attachment to a support, for. As a wall or a ceiling, and the other part is formed by an at least partially transparent cover, which is releasably connected by closure elements with the trough-shaped housing. In the lamp housing formed by the trough-shaped housing and the cover, a lamp can be mechanically and electrically connected, the radiated during operation light emits through the transparent cover for room lighting.

Eine Leuchte dieser Art ist z. B. in der EP 0 785 391 A1 beschrieben. Bei dieser vorbekannten Leuchte dienen zum Befestigen der Abdeckung am wannenförmigen Gehäuse prinzipiell C-förmige Verschlußelemente, die als separate Bauteile ausgebildet sind, und von denen der eine Endbereich der C-Form mit einem Arretierschenkel in eine taschenförmige Hinterschneidung am wannenförmigen Gehäuse eingreift, sich über die Teilungsfuge zwischen dem wannenförmigen Gehäuse und der Abdeckung hinaus erstreckt und mit seinem anderen Endbereich der C-Form einen Rand der Abdeckung mit einer gewissen Zugspannung hintergreift und dadurch das wannenförmige Gehäuse und die Abdeckung mit einer gewissen elastischen Klemmspannung zusammendrückt. Die Ausbildung der Verschlußelemente als separate Bauteile erleichtert zwar deren Herstellung, insbesondere im Hinblick auf deren komplizierte Konstruktion, jedoch ist dadurch der Nachteil gegeben, dass die Verschlußelemente zum einen als separate Bauteile bereitgestellt und gehandhabt werden müssen und zum anderen verlorengehen können.A lamp of this type is z. B. in the EP 0 785 391 A1 described. In this prior art luminaire are used to attach the cover to the trough-shaped housing in principle C-shaped closure elements, which are formed as separate components, and of which engages an end portion of the C-shape with a locking leg in a pocket-shaped undercut on the trough-shaped housing, over the Dividing joint between the trough-shaped housing and the cover extends beyond and engages with its other end portion of the C-shape edge of the cover with a certain tensile stress and thereby compresses the trough-shaped housing and the cover with a certain elastic clamping voltage. Although the formation of the closure elements as separate components facilitates their production, in particular with regard to their complicated construction, but this has the disadvantage that the closure elements must first be provided and handled as separate components and lost to others.

Ein anderer Nachteil der vorbekannten Leuchte ist durch die komplizierte Konstruktion der Verschlußelemente, insbesondere in deren in die taschenförmigen Hinterschneidenungen des wannenförmigen Gehäuses einfassenden Endbereichen vorgegeben. In diesem Endbereich ist nämlich bei der bekannten Leuchte ein Arretierschenkel angeordnet, der sich schräg in die Montagerichtung in der taschenförmigen Hinterschneidung erstreckt, in der der zugehörige Endbereich der C-Form das wannenförmige Gehäuse hintergreift. Aufgrund dieser Schrägerstreckung des Arretierschenkels bedarf es einer besonderen Formgebung, um den Arretierschenkel in die taschenförmige Hinterschneidung einschieben zu können. Außerdem besteht die Gefahr, dass der Arretierschenkel über seinen Totpunkt hinaus überdrückt wird.Another disadvantage of the prior art lamp is due to the complicated construction of the closure elements, in particular in the pocket-shaped Given undercuts of the trough-shaped housing enclosing end portions. In this end, namely, a locking leg is arranged in the known light, which extends obliquely in the mounting direction in the pocket-shaped undercut, in which the associated end portion of the C-shape engages behind the trough-shaped housing. Due to this oblique extension of the locking leg, a special shape is required in order to be able to insert the locking leg into the pocket-shaped undercut. There is also the danger that the locking leg is over-pushed beyond its dead center.

Aus der EP 0 947 766 A2 ist eine Feuchtraumleuchte mit einem Gehäuse bekannt, an das von unten eine Wanne angesetzt ist. Zur Halterung der Wanne dienen Haltebügel, die mit Klemmhaken in Gehäusetaschen eingesetzt sind.From the EP 0 947 766 A2 is a wet room light known with a housing to which a pan is attached from below. To hold the tub are brackets, which are inserted with clamping hooks in housing pockets.

Der Erfindung liegt die Aufgabe zugrunde, eine Leuchte der eingangs angegebenen Art bezüglich der Sicherung des Endbereichs in der Tasche zu verbessern und zu vereinfachen. Dabei ist nicht nur angestrebt, eine geringe Anzahl der Bauteile zu gewährleisten, sondern auch einfache Formgebungen zu finden, die eine kostengünstige Herstellung, Montage, Unverlierbarkeit der Verschlußelemente und/oder die Herstellung aus einem Duroplast erleichtern bzw. ermöglichen.The invention has for its object to improve a light of the type specified in terms of securing the end portion in the bag and simplify. It is not only intended to ensure a small number of components, but also to find simple shapes that facilitate or allow cost-effective production, assembly, captive closure elements and / or the production of a thermosetting plastic.

Deshalb reicht es aus, wenn im Folgenden jeweils nur eine Verschlußvorrichtung 3 der verschiedenen Ausführungsbeispiele beschrieben wird.The majority of the existing closure devices 3 are equal to each other and arranged on both sides mirror images of each other and formed. Therefore, it is sufficient if in the following only one closure device 3 of the various embodiments will be described.

Bei allen Ausführungsbeispielen weist die Verschlußvorrichtung 3 ein Verschlußelement 3a in einer prinzipiell C-förmigen Längs-Querschnittsform auf, dessen Endbereiche mit 3b, 3c bezeichnet sind, das mit seinem oberen Endbereich 3b das wannenförmige Gehäuse 2 hintergreift und gleichzeitig in eine Ausnehmung, insbesondere eine Tasche 13, im Gehäuse 2 eingreift, die zur der Teilungsfuge 7 abgewandten Seite hin offen ist, und mit zwei einander gegenüberliegenden Taschenwänden 13a, 13b, die sich etwa parallel zur Längsmittelebene 15 erstrecken, an die Größe des Endbereichs 3b mit Bewegungsspiel angepaßt ist. Die Ausnehmung bzw. Tasche 13 kann sich in der Längsrichtung der Leuchte 1 jeweils nur auf einen Abschnitt oder durchgehend erstrecken.In all embodiments, the closure device 3, a closure element 3a in a generally C-shaped longitudinal cross-sectional shape, whose end portions are designated 3b, 3c, which engages behind the trough-shaped housing 2 with its upper end portion 3b and at the same time in a recess, in particular a pocket 13, in the housing 2, which is open to the dividing joint 7 side facing away, and with two opposite pocket walls 13 a, 13 b, which extend approximately parallel to the longitudinal center plane 15, is adapted to the size of the end portion 3 b with movement play. The recess or pocket 13 may extend in the longitudinal direction of the lamp 1 in each case only to a portion or continuously.

Das Verschlußelement 3a erstreckt sich vom Endbereich 3b im wesentlichen in einer an die zugehörige Außenform des Gehäuses 2 angepaßten Form außen am Leuchtengehäuse zur Abdeckung 4 hin, wobei es sich über die Teilungsfuge 7 hinaus erstreckt und mit dem zugehörigen Endbereich 3c eine Verbreiterungsstufe 10 an der Abdeckung 4 hintergreift, gegebenenfalls in eine daran ausgebildete Ausnehmung 10a einrastet. Letzteres erfolgt mit einem sich winkelförmig oder gekrümmt nach innen erstreckenden, den Endbereich 3c bildenden Hintergreifschenkel 3d, der durch eine Sicherungsvorrichtung 14 in seiner Hintergreifstellung gesichert ist.The closure element 3a extends from the end portion 3b substantially in a matched to the associated outer shape of the housing 2 shape on the outside Luminaire housing to the cover 4 out, where it extends beyond the dividing joint 7 and with the associated end portion 3c a widening step 10 engages behind the cover 4, optionally engages in a recess 10a formed thereon. The latter is carried out with an angled or curved inwardly extending, the end portion 3c forming Hintergreifschenkel 3d, which is secured by a securing device 14 in its engaged position.

Die Sicherungsvorrichtung 14 kann dadurch gebildet sein, dass der Hintergreifschenkel 3d bezüglich der sich quer bzw. rechtwinklig zur Teilungsfuge 7 erstreckenden Längsmittelebene 15 der Leuchte 1 schräg nach innen elastisch gegen die Verbreiterungsstufe 10 vorgespannt ist, so dass diese Spannung ihn nach innen und nicht nach außen zieht. Dies wird dadurch erreicht, dass der Hintergriff des Endbereichs 3c in einem Abstand a von der Längsmittelebene 15 angeordnet ist, der größer ist als der Abstand b des Hintergriffs des Endbereichs 3b von der Längsmittelebene 15. Hierdurch ergibt sich aufgrund der im elastisch aufgebogenen Zustand mit einer elastischen Spannung an der Verbreiterungsstufe 10 anliegende Hintergreifschenkel 3d eine Spannkraft 16, deren Wirkrichtung einen spitzen Winkel W1 mit der Längsmittelebene 15 einschließt. Diese Spannkraft kann durch eine elastische Aufbiegung des Endbereichs 3b und/oder des Endbereichs 3c und/oder der der Verbreiterungsstufe 9 bezüglich der Stufenform folgenden und ausgebogenen Form des Verschlußelements 3a beruhen.The securing device 14 can be formed in that the Hintergreifschenkel 3d is biased obliquely inwardly against the widening step 10 with respect to the transversely or perpendicular to the dividing joint 7 extending longitudinal center plane 15 of the lamp 1, so that this voltage him inward and not outward draws. This is achieved in that the rear grip of the end portion 3c is arranged at a distance a from the longitudinal center plane 15, which is greater than the distance b of the rear grip of the end portion 3b of the longitudinal center plane 15. This results from the elastically bent state with a elastic clamping voltage applied to the widening step 10 Hintergreifschenkel 3d a clamping force 16, the effective direction includes an acute angle W1 with the longitudinal center plane 15. This clamping force can be based on an elastic bending of the end region 3b and / or the end region 3c and / or the shape of the closure element 3a that follows the widening step 9 with respect to the step shape.

Das Verschlußelement 3a ist durch einen sich über seine gesamte Länge flach erstreckenden Steg 3e gebildet, dessen Dicke mit d' bezeichnet ist.The closure element 3a is formed by a flat over its entire length extending web 3e, whose thickness is denoted by d '.

Der hakenförmig zum freien Endbereich 3c hin abstehende Endbereich 3b des Verschlußelements 3a ist durch eine Arretiervorrichtung 17 in der Tasche 13 gegen ein ungewolltes Herausziehen und somit Lösen arretiert. Für eine solche Arretierung gibt es mehrere Ausführungsbeispiele.The hook-shaped to the free end portion 3c projecting end portion 3b of the closure element 3a is locked by a locking device 17 in the pocket 13 against accidental withdrawal and thus loosening. For such a lock, there are several embodiments.

Beim Ausführungsbeispiel nach Fig. 2 -das kein Bestandteil der Erfindung ist- ist der Endbereich 3b durch wenigstens eine wellenförmige quer zur Mittelachse 13c der Tasche 13 und vorzugsweise nach außen gerichtete Ausformung 18 des den Endbereich 3b bildenden Stegabschnitts 3f realisiert. Dabei kann die Ausformung 18 mit zwei Winkelschenkeln 18a, 18b gebildet sein, die einen Winkel W2 einschließen, der vorzugsweise stumpf ist. Im entspannten bzw. demontierten Zustand des Endbereichs 3b ist die quer zur Tasche 13 gerichtete Abmessung der Ausformung 18 größer als die zugehörige Querabmessung c der Tasche 13. Das nicht dargestellte Übermaß und die Biegefestigkeit des die Ausformung 18 bildenden Stegabschnitts 3f bzw. der Winkelschenkel 18a, 18b sind so groß, dass die Ausformung 18 beim Einstecken bzw. Montieren des Endbereichs 3b in die Tasche 13 durch eine manuell handhabungsfreundlich aufbringbare und in die Tasche 13 hineingerichtete Druckkraft elastisch zusammendrückbar ist, wobei in der eingeschobenen Stellung des Endbereichs 3b die Ausformung 18 an drei Fuß- und Scheitelpunkten bzw. - linien 22a, 22b, 22c an den einander gegenüberliegenden Wänden 13a, 13b der Tasche 13 mit elastischer Spreizkraft P1, P2, P3 anliegen, nämlich bei 22a und 22c am Anfang und am freien Ende der Ausformung 18 und bei 22b im Bereich des Scheitels der Ausformung 18, der sich im Hinblick auf die durch die elastische Rückfederung der Ausformung 18 erzeugte und gegen die Wände der Tasche 13 wirksame Klemmkraft der Dreipunkt-Anlage sich zwischen den Anlagestellen 22a, 22c befindet. Es ist zur Erleichterung des Einschiebens des freien Winkelschenkels 18b vorteilhaft, die Übergänge der Ausformung 18 bzw. der Winkelschenkel 18a, 18b gerundet auszubilden. Hierdurch gleitet der ausgeformte Stegabschnitt 3f beim Eindrücken und Herausziehen in bzw. aus der Tasche 13 vorteilhaft an deren Wänden 13a, 13b, wodurch sich die erforderliche Eindrückkraft gering halten läßt. Die Rundung am freien Ende des Winkelschenkels 18b kann durch eine gerundete Ausbiegung mit einem Schenkelstumpf 18c gebildet sein.According to the embodiment Fig. 2 which is not part of the invention, the end region 3b is realized by at least one wave-shaped transverse to the central axis 13c of the pocket 13 and preferably outwardly directed formation 18 of the web portion 3f forming the end region 3b. In this case, the formation 18 may be formed with two angle legs 18a, 18b, which enclose an angle W2, which is preferably blunt. In the relaxed or disassembled state of the end portion 3b, the transverse direction of the pocket 13 dimension of the formation 18 is greater than the corresponding transverse dimension c of the pocket 13. The oversize and bending strength of the forming the web 18 forming web portion 3f or the Angle legs 18a, 18b are so large that the molding 18 during insertion or mounting of the end portion 3b in the pocket 13 by a manually handling friendly applied and directed into the bag 13 compressive force is elastically compressible, wherein in the retracted position of the end portion 3b, the formation 18 at three feet and apexes or lines 22a, 22b, 22c abut against the opposing walls 13a, 13b of the pocket 13 with elastic spreading force P1, P2, P3, namely at 22a and 22c at the beginning and at the free end of the formation 18 and 22 b in the region of the apex of the molding 18, which is in view of the generated by the elastic resilience of the molding 18 and against the walls of the pocket 13 clamping force of the three-point system between the abutment points 22 a, 22 c. It is advantageous for facilitating the insertion of the free angle leg 18b, the transitions of the formation 18 and the angle legs 18a, 18b rounded form. As a result, the molded web portion 3f slides when pushing in and out of the pocket 13 advantageously on the walls 13a, 13b, which can be the required Eindrückkraft keep low. The rounding at the free end of the angle leg 18b may be formed by a rounded deflection with a thigh stump 18c.

Die Ausgestaltungen der Verschlußelemente 3a und des Gehäuses 2, zeichnen sich durch einfache Formgebungen aus, die sich auch für eine Herstellung aus einem Duroplast eignen.The embodiments of the closure elements 3a and the housing 2, characterized by simple shapes, which are also suitable for production from a thermosetting plastic.

Beim Ausführungsbeispiel nach Fig. 3 und 4, bei dem gleiche oder vergleichbare Teile mit gleichen Bezugszeichen versehen sind, ist der Endbereich 3b des Verschlußelements 3a gegebenenfalls zusätzlich zur vorbeschriebenen Arretierung durch wenigstens einen Arretierschenkel 17a in der Tasche 13 arretiert, der vom Endbereich 3b seitlich absteht, elastisch aus- und einfederbar ist sowie einen stumpfen Winkel W3 mit einer Längsmittelachse 3i des Endbereichs 3b einschließt, der zum freien Ende des Endbereichs 3b und somit auch zum Grund der Tasche 13 hin offen ist. Beim Ausführungsbeispiel beträgt der Winkel W3 etwa 92° bis etwa 100°, wobei die Länge L2 des Arretierschenkels 17a so lang bemessen ist, dass er beim Einschieben des Endbereichs 3b in die Tasche 13 an der ihm gegenüberliegenden Taschenwand 13a einfedert und somit mit einer Ausfederspannung an der Taschenwand 13a anliegt. Bei dieser Ausgestaltung übt der Arretierschenkel 17a eine Sperrwirkung gegen ein Herausziehen des Endbereichs 3b aus der Tasche 13 aus, die dadurch vorgegeben ist, dass der Arretierschenkel 17a beim Herausziehen des Endbereichs 3b aufgrund der Haftreibung an der Taschenwand 13a weiter ausgebogen wird und dadurch die Herausziehbewegung sperrt. Diese Sperrwirkung ist besonders gut, wenn das freie Ende des Arretierschenkels 17a mit einer Anlagekante 17b an der Taschenwand 13a anliegt, die die Haftreibung vergrößert und die Sperrwirkung verstärkt.According to the embodiment 3 and 4 in which the same or similar parts are provided with the same reference numerals, the end portion 3b of the closure element 3a is optionally locked in addition to the above-described locking by at least one locking leg 17a in the pocket 13, which laterally protrudes from the end portion 3b, is elastically off and einfederbar and includes an obtuse angle W3 with a longitudinal center axis 3i of the end portion 3b, which is open to the free end of the end portion 3b and thus also to the bottom of the pocket 13. In the exemplary embodiment, the angle W3 is about 92 ° to about 100 °, wherein the length L2 of the locking leg 17a is dimensioned so long that it springs when inserting the end portion 3b in the pocket 13 on the opposite pocket wall 13a and thus with a rebound the pocket wall 13a rests. In this embodiment, the locking leg 17a exerts a blocking action against withdrawal of the end portion 3b from the pocket 13, which is predetermined by the fact that the locking leg 17a upon withdrawal of the end portion 3b due to the static friction on the Pocket wall 13a is further bent and thereby blocks the withdrawal movement. This blocking effect is particularly good when the free end of the locking leg 17a abuts with a contact edge 17b on the pocket wall 13a, which increases the static friction and reinforces the blocking effect.

Der Arretierschenkel 17a kann sich bezüglich seiner parallel zur Teilungsfuge erstreckenden Breite über die gesamte Breite e des Verschlußstegs 3f oder nur über einen Teil dieser Breite e erstrecken. Es können auch mehrere Arretierschenkel 17a in der Breiten- und/oder Längsrichtung des Verschlußelements 3a angeordnet sein, z. B. zwei Stück Arretierschenkel 17a, die sich z. B. an den einander gegenüberliegenden Rändern des Endbereichs 3b bzw. Stegs 3f befinden (Fig. 4).With regard to its width extending parallel to the dividing joint, the arresting leg 17a can extend over the entire width e of the closing web 3f or only over a part of this width e. It can also be arranged a plurality of locking legs 17a in the width and / or longitudinal direction of the closure element 3a, z. B. two pieces locking leg 17a, z. B. on the opposite edges of the end portion 3b or web 3f ( Fig. 4 ).

Das Verschlußelement 3a kann auch aus Metall, insbesondere korrosionsfestem Metall wie rostfreier Stahl oder Federstahl, oder Kunststoff bestehen. Bei allen Ausgestaltungen ist es vorteilhaft, den Arretierschenkel 17a einteilig am Endbereich 3b auszubilden. Dies kann bei einem aus Kunststoff bestehenden Verschlußelement 3a durch Spritzgießen oder bei einem aus Metall bestehenden Verschlußelement 3a durch ein Ausbiegen einer den Arretierschenkel 17a bildenden Zunge erfolgen, die z. B. vom übrigen Teil des Endbereichs 3b jeweils durch einen Freischnitt 3h freigeschnitten ist.The closure element 3a may also consist of metal, in particular corrosion-resistant metal such as stainless steel or spring steel, or plastic. In all embodiments, it is advantageous to form the locking leg 17a in one piece at the end region 3b. This can be done in a plastic closure element 3a by injection molding or in a metal closure element 3a by bending a locking leg 17a forming tongue z. B. from the remaining part of the end portion 3 b is cut free in each case by a free cut 3 h.

Bei dem Endbereich 3b kann es sich um einen sich gerade in die Tasche 13 hineinerstreckenden Abschnitt des Verschlußelements 3a handeln. Wenn der Endbereich 3b gemäß dem Ausführungsbeispiel nach Fig. 2 bis 4 durch die wellenförmig Ausformung 18 gebildet ist, ist es vorteilhaft, den wenigstens einen Arretierschenkel 17a an einem der beiden Winkelschenkel 18a, 18b anzuordnen, z. B. in deren Scheitelbereich, wie es die Ausführungsbeispiele gemäß Fig. 3 und 4 zeigen.The end region 3b can be a section of the closure element 3a extending straight into the pocket 13. When the end portion 3b according to the embodiment of Fig. 2 to 4 is formed by the wave-shaped formation 18, it is advantageous to arrange the at least one locking leg 17a on one of the two angle legs 18a, 18b, z. B. in the apex area, as in the embodiments according to 3 and 4 demonstrate.

Wesentlich ist, dass der Endbereich 3b beim Vorhandensein eines Arretierschenkels 17a an der dem freien Ende des Arretierschenkels 17a gegenüberliegenden Seite, z. B. an der der Taschenwand 13a gegenüberliegenden Taschenwand 13b der Tasche 13, abgestützt ist.It is essential that the end portion 3b in the presence of a locking leg 17a at the free end of the locking leg 17a opposite side, z. B. at the pocket wall 13 a opposite pocket wall 13 b of the bag 13, is supported.

Wenn es sich bei dem wannenförmigen Gehäuse 2 um ein Kunststoffspritzteil handelt, ist es aus Entformungsgründen erforderlich, die einander gegenüberliegenden Taschenwände 13a, 13b zur Öffnung der Tasche 13 hin etwas divergent auszubilden. Diese Divergenz ist vernachlässigbar gering, und deshalb wird sie im vorliegenden Zusammenhang mit der selbsttätig wirkenden Sperrwirkung des Arretierschenkels 17a nicht näher beschrieben. Die Ausführungsbeispiele gemäß Fig. 5 und 6 zeigen beispielhaft einen oder mehrre übereinander angeordnete Arretierschenkel 17a, die sich z. B. über die gesamte Breite d des Verschlußelements 3a bzw. Endbereichs 3b erstrecken. Eine solche Ausgestaltung eignet sich besonders gut für Verschlußelemente 3a, die aus Kunststoff bestehen, wobei der oder die Arretierschenkel 17a beim Spritzvorgang einteilig angeformt werden können.If it is the trough-shaped housing 2 is a plastic injection molded part, it is necessary for Entformungsgründen, the opposing pocket walls 13a, 13b to form the opening of the bag 13 towards something divergent. This divergence is negligible, and therefore it is not described in detail in the present context with the self-acting blocking effect of the locking leg 17a. The embodiments according to FIGS. 5 and 6 show by way of example one or more superimposed locking leg 17a, the z. B. extend over the entire width d of the closure element 3a and end portion 3b. Such a configuration is particularly well suited for closure elements 3a, which are made of plastic, wherein the one or more locking legs 17a can be integrally formed during the injection process.

Beim Ausführungsbeispiel nach Fig. 5 ist bzw. sind an einem sich in Form eines etwa gerade erstreckenden Steges 3f, der an der ihm zugewandten Taschenwand 13b vorzugsweise im wesentlichen flächig anliegt, eine oder mehrere Arretierschenkel 17a angeordnet, die einen konvergenten, z. B. keilförmigen Querschnitt aufweisen. Dabei ist die über die Dicke des Stegs 3f gemessene wirksame Länge des wenigstens einen Arretierschenkels 17a etwas größer als die Querabmessung c der Tasche 13, so dass jeweils im eingeschobenen Zustand der Arretierschenkel 17a geringfügig nach oben elastisch ausbiegt und aufgrund seiner Anlage an der Taschenwand 13a beim Herausziehen des Endbereichs 3b die angestrebte Sperrwirkung ausübt, die sich aufgrund des Reibschlusses zwischen der Taschenwand 13a und dem Ende des Arretierschenkels 17a ergibt.According to the embodiment Fig. 5 is or are at one in the form of an approximately straight extending web 3f, which preferably abuts substantially flat on the facing it pocket wall 13b, one or more locking legs 17a arranged, which has a convergent, z. B. have wedge-shaped cross-section. In this case, the measured over the thickness of the web 3f effective length of at least one locking leg 17a is slightly larger than the transverse dimension c of the pocket 13, so that in each case in the retracted state of the locking leg 17a elastically deflects slightly upward and due to its abutment against the pocket wall 13a Pulling out the end portion 3b exerts the desired locking effect, which results from the frictional engagement between the pocket wall 13a and the end of the locking leg 17a.

Eine ähnliche Ausgestaltung ist auch in Fig. 7 und 8 dargestellt, jedoch mit dem Unterschied, dass der wenigstens eine Arretierschenkel 17a zwar elastisch einschwenkbar sein kann, jedoch nicht muß, was dann der Fall ist, wenn er durch ein dünnes Filmscharnier 21 ebenfalls mit dem sich vorzugsweise gerade erstreckenden Steg 3f verbunden ist. Bei dieser Ausgestaltung ist die sich beiderseits zum mittleren Bereich des Arretierschenkels 17a hin verbreiternde Querschnittsgröße so ausgebildet, dass beim Herausziehen des Endbereichs 3b der wenigstens eine Arretierschenkel 17a gedreht wird und dabei aufgrund seiner exzentrischen Form die quergerichtete Klemmwirkung des Arretierschenkels 17a gegen die Taschenwand 13a herbeiführt. Hierdurch wird der Steg 3f gegen die gegenüberliegende Taschenwand 13b gedrückt und geklemmt.A similar embodiment is also in FIGS. 7 and 8 illustrated, but with the difference that the at least one locking leg 17a may be elastically einschwenkbar, but need not, as is the case when it is also connected by a thin film hinge 21 with the preferably straight extending web 3f. In this embodiment, the cross-sectional size widening on both sides towards the central region of the locking leg 17a is such that when the end region 3b is withdrawn the at least one locking leg 17a is rotated, thereby causing the transverse clamping effect of the locking leg 17a against the pocket wall 13a due to its eccentric shape. As a result, the web 3f is pressed against the opposite pocket wall 13b and clamped.

Bei den erfindungsgemäßen Ausgestaltungen ist eine Sicherung des Endbereichs 3b in der Tasche 13 gewährleistet, die ein ungewolltes Lösen und Verlorengehen des Verschlußelementes 3a verhindert. In den Fällen, in denen jedoch ein Lösen des Endbereichs 3b gewollt ist, ist es möglich, beim Ausführungsbeispiel gemäß Fig. 2 durch eine z. B. mit einem Werkzeug, aufgebrachte erhöhte Zugkraft den Endbereich 3b aus der Tasche 13 herauszuziehen. Außerdem ist es bei den Ausführungsbeispielen gemäß Fig. 3 und folgende möglich, durch ein vorzugsweise elastisches Biegen des oder der Arretierschenkel 17a in die Freigabestellung, z. B. mittels eines Werkzeugs, den Endbereich 3b aus der Tasche 13 herauszuziehen.In the embodiments according to the invention, a securing of the end region 3b in the pocket 13 is ensured, which prevents unwanted loosening and loss of the closure element 3a. However, in cases where detachment of the end portion 3b is desired, it is possible in the embodiment of FIG Fig. 2 by a z. B. with a tool, applied increased tensile force to pull the end portion 3b from the pocket 13. In addition, it is according to the embodiments Fig. 3 and the following possible, by a preferred elastic bending of the locking leg or 17 a in the release position, z. B. by means of a tool to pull the end portion 3b from the pocket 13.

Es ist zwecks Abdeckung der jeweiligen Ausnehmung bzw. Tasche 13 bei allen Ausführungsbeispielen vorteilhaft, im Fußbereich des Endbereichs 3b bzw. Stegs 3f einen Abdeckschenkel 3g abstehend anzuordnen, der in der eingesteckten Stellung die Tasche 13 abdeckt.For the purpose of covering the respective recess or pocket 13, it is advantageous in all exemplary embodiments to arrange a covering leg 3g in the foot region of the end region 3b or web 3f which covers the pocket 13 in the inserted position.
