Description

Die Erfindung betrifft eine Sicherungsvorrichtung für eine Entwässerungsrinne nach dem Oberbegriff des Patentanspruchs 1 als Zusatz zur Patentanmeldung 198 46 668.4-25.The invention relates to a safety device for a Drainage channel according to the preamble of claim 1 as an addition to patent application 198 46 668.4-25.

Aus der DE 42 41 707 ist eine Sicherungseinrichtung für eine Entwässerungsrinne bekannt, bei der eine Traverse mit ihren Enden in Ausnehmungen einsetzbar ist, die sich in Seiteninnenwänden einer Rinne befinden.DE 42 41 707 is a safety device for a Drainage gutter known in which a traverse with its Ends can be used in recesses that are located in the inner side walls a gutter.

Die Traverse verläuft quer zur Rinnen-Längsachse im Inneren der Rinne und umfaßt Befestigungseinrichtungen, um eine Abdeckung an der Traverse und dadurch an der Rinne zu befestigen.The traverse runs transversely to the longitudinal axis of the gutter inside the Gutter and includes fasteners to a cover to be attached to the traverse and thereby to the gutter.

Die in der DE 42 41 707 beschriebene Traverse weist eine Klemmeinrichtung auf, die derart elastisch verformbar ist, daß sie beim Einsetzen in die Ausnehmungen der Rinne durch die Einsatzbewegung der Traverse verformt wird. Die Klemmeinrichtung besteht hierbei aus einer Klemmfeder, die entweder aus Kunststoff oder aus einem Edelstahlband gefertigt ist. Mittels einer solchen Einrichtung läßt sich die Traverse zwar auf einfache Weise in die Entwässerungsrinne einsetzen, sie weist jedoch gravierende Nachteile auf, da ein derartiges Befestigungssystem in der Herstellung teuer ist, weil insbesondere bei großen lichten Weiten der Rinne ein Kunststoffteil nicht die notwendige Festigkeit aufweist und Federbandedelstahl verwendet werden muß, der jedoch sehr kostenintensiv ist. Weiterhin erfordert die Geometrie der in der Druckschrift beschriebenen Befestigungseinrichtung einen erheblichen Materialeinsatz, wobei außerdem der Durchflußquerschnitt in Flachrinnensystemen reduziert wird.The traverse described in DE 42 41 707 has one Clamping device which is so elastically deformable that when inserting them into the recesses in the gutter Deployment movement of the traverse is deformed. The clamping device consists of a clamping spring, which either Plastic or made of a stainless steel band. Means such a device, the traverse can be simply insert into the drainage channel, it points however, there are serious disadvantages, since such a fastening system is expensive to manufacture, especially because a large plastic part of the gutter is not a plastic part has the necessary strength and uses spring band stainless steel must be, but which is very expensive. Farther requires the geometry of that described in the publication Fastening device a considerable use of material, where also the flow cross-section in shallow channel systems is reduced.

Darüber hinaus wird beim Einbau der Traverse gemäß der in der DE 42 41 707 beschriebenen Lehre ein Federdruck auf die Seitenwände der Rinne ausgeübt, was deren Stabilität, insbesondere bei kleinen Baugrößen der Rinne, beeinträchtigen kann. Letztendlich ist eine exakte Positionierung der Traverse schwierig, da beim Einsetzen dieser gegen die stärker werdende Federkraft der Befestigungseinrichtung gearbeitet werden muß. Falls die Position der Traverse korrigiert werden muß, so ist die zum Herausnehmen der Traverse aus den Ausnehmungen der Rinne nötige Kraft sogar wesentlich höher als die zum Einsetzen der Traverse nötige Kraft.In addition, when installing the traverse in accordance with the DE 42 41 707 described a spring pressure on the Side walls of the gutter exerted, what their stability, in particular with small sizes of the gutter. Ultimately, there is an exact positioning of the traverse difficult because when you insert this against the growing Spring force of the fastening device must be worked. If the position of the traverse needs to be corrected, then those for removing the traverse from the recesses of the The gutter force required is much higher than that required for insertion the traverse necessary power.

Weiterhin ist aus dem deutschen Gebrauchsmuster DE 91 16 688 eine Verriegelungsvorrichtung zum Halten einer überfahrbaren Abdeckung auf einer Entwässerungsrinne bekannt, wobei dort Verriegelungsteile und ein bewegbares Verriegelungsstück vorgesehen sind, welches ein quasi selbsttätiges Nachspannen der Verbindungsvorrichtung gewährleistet, so daß ein Abdeckrost auch dann sicher auf einer Rinne gehalten ist, wenn Materialverformungen oder Abnutzungserscheinungen auftreten.Furthermore, from German utility model DE 91 16 688 a locking device for holding a drive over Coverage known on a drainage channel, being there Locking parts and a movable locking piece are provided which is a quasi automatic retensioning of the Connection device ensures that a cover grate is also held securely on a gutter when material is deformed or wear and tear.

Die Aufgabe der vorliegenden Erfindung ist es, eine weiterentwickelte Sicherungsvorrichtung für eine Entwässerungsrinne zur Verfügung zu stellen, bei der zum einen der Materialbedarf verringert ist und zum anderen ein kostengünstigeres Material verwendet werden kann, wobei weiterhin der Durchflußquerschnitt in Rinnensystemen nicht wesentlich reduziert ist.The object of the present invention is to develop a further Safety device for a drainage channel to provide, on the one hand, the material requirements is reduced and secondly a cheaper material can be used, the flow cross-section continues is not significantly reduced in gutter systems.

Diese Aufgabe wird mit einer Vorrichtung gemäß den Merkmalen des Patentanspruchs 1 gelöst, wobei die Unteransprüche mindestens zweckmäßige Ausgestaltungen und Weiterbildungen umfassen. This task is accomplished with a device according to the features of claim 1 solved, the subclaims at least practical refinements and developments include.

Ein wesentlicher Gedanke der Erfindung liegt darin, daß die an sich bekannte Traverse mühelos und ohne jeden wesentlichen Krafteinsatz exakt in ihrer vorbestimmten Position angeordnet werden kann. Erst wenn dies geschehen ist, wird die Traverse mit Hilfe einer speziellen Blockierklammer gegen unbeabsichtigtes Lösen fixiert. Da die Traverse bei diesem Vorgang innerhalb der Ausnehmungen des Rinnenkörpers bereits geführt und/oder gehalten wird, ist eine Lageveränderung während des Befestigungsvorgangs nahezu ausgeschlossen.An essential idea of the invention is that the known traverse effortlessly and without any essential Force application arranged exactly in their predetermined position can be. Only when this has been done will the traverse with the help of a special blocking clip against accidental Loosen fixed. Because the traverse in this process already performed within the recesses of the channel body and / or is held, a change of position during the Fastening process almost impossible.

Ein weiterer wesentlicher Aspekt der vorliegenden Erfindung besteht in der Ausgestaltung des Blockierelementes als auswechselbare Blockierklammer, die derart beweglich an der Traverse bzw. Lasche angebracht ist, daß eine Lageveränderung zwischen einer Montage- und Arretierungsposition möglich ist. Je nach Lage - Montage- bzw. Arretierungszustand - wirken hierbei die Lasche und die Blockierklammer derart rastend und/oder klemmend zusammen, daß die Blockierklammer ohne Aktivitäten für ein beabsichtigtes Entfernen der Klammer unverlierbar an der Lasche fixiert ist.Another essential aspect of the present invention consists in the design of the blocking element as interchangeable locking clip that is so flexible on the Traverse or tab is attached that a change in position between an assembly and locking position is possible. Depending on the position - installation or locking status - act the tab and the locking clip latching in this way and / or clamped together that the blocking clip without Activities for deliberate removal of the bracket is captively attached to the tab.

Erfindungsgemäß ist die Lasche kostengünstig aus Edelstahl mit einem aufgrund der vorteilhaften Geometrie der Lasche geringerem Materialeinsatz herstellbar. Alternativ kann die Lasche auch aus einem anderen, dem strömenden Medium in der Rinne gegenüber inerten Material hergestellt werden.According to the invention, the tab is inexpensively made of stainless steel one due to the advantageous geometry of the tab less material can be produced. Alternatively, the Tab from another, the flowing medium in the Gutter versus inert material.

Für das Anbringen der Rinnenabdeckung ist in der Lasche vorzugsweise eine Aussparung vorgesehen, die sich im wesentlichen in der Mitte an der Oberseite der Lasche in eingebautem Zustand befindet. Die Befestigung der Abdeckung an der Traverse erfolgt vorzugsweise nach den in der DE 42 41 706 und der DE 42 41 707 beschriebenen Verfahren. Diese Verfahren stellen eine bevorzugte Ausführungsform dar, wobei jedoch auch andere Befestigungsarten, wie z.B. ein seitliches Umklammern der Traverse bzw. Lasche denkbar sind. For attaching the gutter cover is preferred in the tab a recess is provided, which is essentially in the middle at the top of the tab when installed located. The cover is attached to the crossbar preferably according to those in DE 42 41 706 and DE 42 41 707 described method. These methods are preferred Embodiment, but other types of attachment, such as. a lateral gripping of the traverse or tab are conceivable.

Bei der speziellen erfindungsgemäßen Blockierklammer ist ein Führungsschenkel und ein Rastschenkel vorgesehen, wobei die beiden Schenkel in ihrer relativen Lage zueinander bewegbar sind. Der Rastschenkel weist eine Anlaufschräge mit einem ersten Rücksprung sowie einen hiervon in Längsrichtung beabstandeten zweiten Rücksprung auf. Die Anlaufschräge gleitet über den entsprechenden Abschnitt der Traverse, wobei die bevorzugt unmittelbar hinter der Anlaufschräge befindliche erste Rücksprungausnehmung zu einem Einrasten der Klammer in Montageposition führt.
Die Traverse ist mit den in Montageposition befindlichen Klammern in den Rinnenkörper einsetzbar und wird in die dortigen Ausnehmungen hineingeschwenkt. Durch weiteres Hineindrücken der Blockierklammer in die Öffnungen der Lasche wird dann eine Position derart erreicht, daß durch ein Inkontaktkommen des durch die Öffnung hindurch reichenden längeren Schenkels, nämlich des Führungsschenkels, die Lasche gegen unerwünschtes Herausdrehen im Rinnenkörper blockiert ist.
In the special blocking clip according to the invention, a guide leg and a latching leg are provided, the two legs being movable relative to one another. The locking leg has a run-on slope with a first recess and a second recess spaced apart in the longitudinal direction. The run-on slope slides over the corresponding section of the crossmember, the first recess recess, which is preferably located immediately behind the run-on slope, causing the clip to snap into the assembly position.
The crossbar can be inserted into the channel body with the clamps in the assembly position and is pivoted into the recesses there. By pushing the blocking clip further into the openings of the tab, a position is then reached such that the tab, which comes through the opening and which extends through the opening, namely the guide leg, blocks the tab against undesired unscrewing in the channel body.

Die vorerwähnten Schenkel der Blockierklammer verlaufen im wesentlichen parallel, wobei der Rastschenkel gegenüber dem Führungsschenkel zurückgesetzt ist und eine Länge aufweist, die im wesentlichen gleich oder kleiner des Abstands der Schenkel einer U-förmig profilierten Lasche ist.The aforementioned legs of the locking clip run in essentially parallel, the locking leg compared to the Guide leg is reset and has a length that substantially equal to or less than the distance between the legs is a U-shaped tab.

Der Führungsschenkel besitzt einen gestuften Querschnitt mit einem Fortsatz oder einer Nase entsprechend gleichgeformten Öffnungen in der Lasche, so daß die Blockierklammer nur in einer bestimmten Richtung alternierend orientiert in die jeweiligen Enden der Lasche einschiebbar ist.The guide leg has a stepped cross section correspondingly shaped to an extension or a nose Openings in the tab so that the locking clip only in a certain direction alternately oriented in the respective ends of the tab can be inserted.

Der Führungsschenkel selbst ist relativ starr und an einem Ende bogenförmig, den Rastschenkel bildend zurückgeführt, wobei der bogenförmige, die Schenkel verbindende Abschnitt elastische Eigenschaft aufweist. Die Elastizität führt dazu, daß beim Einführen der Blockierklammer in die Öffnungen der Lasche ein Anheben des Rastschenkels über die Anlaufschräge und Zurückschnappen in den ersten Rücksprung für die Montageposition bzw. ein weiteres Anheben des Rastschenkels und Entlanggleiten an einem der Schenkel der U-förmigen Traverse erfolgt, bis die gewünschte Endlage im Bereich des zweiten Rücksprungs erreicht ist. Der zweite Rücksprung ist bevorzugt im bogenförmigen Abschnitt ausgebildet. Zum leichteren Einführen der Blockierklammer weist der Führungsschenkel eine in Längsrichtung sich erstreckende Abschrägung als Einführhilfe auf.The guide leg itself is relatively rigid and at one end arched, forming the locking leg, the arcuate section connecting the legs elastic Has property. The elasticity leads to the fact that Insert the locking clip into the openings in the tab Lift the locking leg over the run-on slope and snap back in the first return for the assembly position or a further lifting of the locking leg and sliding along one of the legs of the U-shaped traverse takes place until the Desired end position reached in the area of the second recess is. The second recess is preferably arcuate Section trained. For easier insertion of the blocking clip the guide leg has one in the longitudinal direction extending bevel as an insertion aid.

Der lichte Innendurchmesser des erwähnten bogenförmigen Abschnitts im Verbindungsbereich zwischen den beiden Schenkeln der Blockierklammer ist größer als der Abstand zwischen den zueinander weisenden Flächen der sich gegenüberliegenden Schenkel, wodurch die gewünschten elastischen Eigenschaften sichergestellt und der erwähnte zweite Rücksprung gebildet werden kann.The inside diameter of the mentioned arcuate Section in the connection area between the two legs the blocking bracket is larger than the distance between the facing surfaces of the opposite Thigh, creating the desired elastic properties ensured and the aforementioned second return formed can be.

Die Erfindung soll nachstehend anhand eines Ausführungsbeispiels sowie unter Zuhilfenahme von Figuren näher erläutert werden.The invention is intended to be explained below using an exemplary embodiment and explained with the help of figures become.

Die in Fig. 1 gezeigte Traverse oder Lasche 1 besitzt einen im wesentlichen U-förmigen Querschnitt 15 mit zwei gegenüberliegenden Schenkeln 2 und einem Verbindungsabschnitt 3. Die gegenüberliegenden Enden 4 der Traverse 1 tauchen im montierten Zustand in im wesentlichen gegenüberliegende Ausnehmungen in Seitenwänden des nicht gezeigten Rinnenkörpers ein, wobei eine nahezu mittig in der Traverse 1 angeordnete Aussparung 5 zur Aufnahme einer Befestigungsfeder oder dergleichen Mittel zum Befestigen des nicht gezeigten Abdeckrosts dient. The traverse or tab 1 shown in Fig. 1 has a essential U-shaped cross section 15 with two opposite Legs 2 and a connecting section 3. The opposite ends 4 of the crossbar 1 dive into the assembled Condition in substantially opposite recesses in Side walls of the channel body, not shown, one Recess 5 arranged almost centrally in the cross member 1 Inclusion of a mounting spring or the like means for Attach the cover grate, not shown.

Die abgekanteten Zungen 6 der Traverse 1 bilden eine Anschlagfläche hin zur Seiteninnenwand des Rinnenkörpers im erwähnten montierten Zustand.The folded tongues 6 of the cross member 1 form a stop surface towards the side inner wall of the channel body in the mentioned assembled condition.

In den Schenkeln 2 der Traverse 1 sind Öffnungen 7 einer bestimmten abgestuften Form ausgebildet, die im wesentlichen der Querschnittsfläche der Blockierklammer nach Fig. 2 entsprechen. Durch die Form der Öffnungen in Verbindung mit der Querschnittsfläche der Blockierklammer ist sichergestellt, daß die Klammern nur in einer bestimmten alternierenden Richtung eingeschoben werden können.In the legs 2 of the cross member 1 openings 7 are one certain graded shape, which is essentially correspond to the cross-sectional area of the blocking clip according to FIG. 2. Due to the shape of the openings in connection with the Cross-sectional area of the blocking clip ensures that the brackets only in a certain alternating direction can be inserted.

Die in den Ansichten nach Fig. 2 gezeigte Blockierklammer besitzt einen oberen längeren Führungsschenkel 8 und einen unteren kürzeren Rastschenkel 9.The locking clip shown in the views of FIG. 2 has an upper longer guide leg 8 and one lower shorter locking leg 9.

Rast- und Führungsschenkel 9/8 sind über einen bogenförmigen Abschnitt 10 in Verbindung stehend. Der bogenförmige Abschnitt 10 führt zu einer beweglichen elastischen Verschiebbarkeit des Rastschenkels 9 bezogen auf den Führungsschenkel 8.Locking and guide legs 9/8 are arcuate Related Section 10. The arcuate section 10 leads to a movable elastic displaceability of the Lock leg 9 related to the guide leg 8.

Der Rastschenkel 9 weist weiterhin eine Anlaufschräge 11 und einen ersten Rücksprung 12 unmittelbar hinter der Anlaufschräge 11 auf.The locking leg 9 also has a run-up slope 11 and a first return 12 immediately behind the ramp 11 on.

Ein zweiter Rücksprung 13 ist im Bereich des bogenförmigen Abschnitts 10 am Rastschenkel 9 ausgebildet.A second recess 13 is in the region of the arc Section 10 formed on the locking leg 9.

Im vormontierten Zustand wird die Blockierklammer in jeweils ein Öffnungspaar 7 der Traverse 1 eingeführt, wobei über die Anlaufschräge 11 der Rastschenkel 9 leicht angehoben wird und unter Entspannung im ersten Rücksprung 12 zu liegen kommt.In the pre-assembled state, the locking clip is in each case a pair of openings 7 of the crossbar 1 is introduced, with the Sloping ramp 11 of the locking leg 9 is slightly raised and comes to rest under relaxation in the first recess 12.

Nachdem die Lasche oder Traverse 1 im Rinnenkörper eingeschwenkt und vorfixiert wurde, erfolgt ein weiteres Beaufschlagen der Blockierklammer mit leichtem Druck auf den bogenförmigen Abschnitt 10 mit der Folge, daß der Rastschenkel 9 über die entsprechende Kante des Traversenschenkels 2 gleitet und im zweiten Rücksprung 13 einrastet. In dieser Position steht der Führungsschenkel 8, welcher eine größere Länge als der Rastschenkel 9 aufweist, aus einer der Öffnungen relativ weit hervor und gelangt mit einer Seite in Kontakt mit der jeweiligen Seiteninnenwand des Rinnenkörpers, so daß ein unerwünschtes Lösen oder Lockern und Herausgleiten der Traverse aus den entsprechenden Ausnehmungen in den Seiteninnenwänden des Rinnenkörpers sicher verhindert ist.After the tab or crossbar 1 is swung into the channel body and has been pre-fixed, a further application is made the blocking clip with light pressure on the arcuate Section 10 with the result that the locking leg 9th slides over the corresponding edge of the truss leg 2 and snaps into the second recess 13. In this position stands the guide leg 8, which is a greater length than has the locking leg 9, from one of the openings relative far out and one side comes into contact with the respective side inner wall of the channel body, so that a unwanted loosening or loosening and sliding out of the traverse from the corresponding recesses in the side walls of the channel body is reliably prevented.

Der Führungsschenkel 8 weist eine durchgehende Nase oder einen Fortsatz 14 auf, wobei der gesamte Querschnitt des Führungs-schenkels bis hin zu einem Endbereich 16 im wesentlichen der Form der Öffnungen 7 in der Lasche 1 entspricht, so daß eine definierte Einführrichtung und ein verwechslungsfreies Befestigen der Blockierklammer gegeben ist.The guide leg 8 has a continuous nose or one Extension 14 on, the entire cross section of the guide leg to an end region 16 essentially the Shape of the openings 7 in the tab 1 corresponds to a defined insertion direction and a mix-up Attach the blocking clip is given.

Zum leichteren Einführen ist der Führungsschenkel 8 an seinem vorderen Ende mit einer in Längsrichtung sich erstreckenden Abschrägung 17 versehen.For easier insertion, the guide leg 8 is on his front end with a longitudinally extending Provide bevel 17.
