Description

Gegenstand der ErfindungSubject of the invention

Die Erfindung betrifft ein Montagesystem zur Befestigung eines Schienenelementes einer Teleskopschiene an einem parallel zur Längserstreckung des Schienenelementes angeordneten Stab, insbesondere einem Gitterstab eines Gitters zur Befestigung von Gargutträgerführungen in einem Backofen.The invention relates to a mounting system for fastening a rail element of a telescopic rail to a rod arranged parallel to the longitudinal extent of the rail element, in particular a grid of a grid for fastening food product guides in an oven.

Hintergrund der ErfindungBackground of the invention

Gargutträger in Backöfen sind in vielfältiger Form bekannt und werden ständig weiterentwickelt und verbessert. Bei einfachen bekannten Backöfen wird der Gargutträger in Nuten geführt, die in verschiedenen Höhen oder Ebenen in der Muffelseitenwand ausgebildet sind. Das Gleitverhalten der Gargutträger in solchen Nuten hängt von der Oberflächenbeschaffenheit der aufeinander gleitenden Flächen und der Belastung des Gargutträgers ab und ist vergleichsweise schlecht. Bei anderen bekannten Systemen sind an Stelle der Nuten an den Muffelseitenwänden Gitter mit horizontalen Stäben oder Drähten mit in der Regel rundem Querschnitt befestigt, auf denen die Gargutträger getragen und geführt werden. Aufgrund der geringeren Auflagefläche ist hier das Gleitverhalten gegenüber Nuten etwas verbessert. Beide Systeme haben den Nachteil, dass der Gargutträger nur bis zu einer bestimmten Weite aus dem Backofen herausgezogen werden kann, ohne dass er nach unten abkippt oder vorne unterstützt werden muss. Bei verbesserten und höherwertigen Backöfen sind an der Muffelseitenwand oder an einem in der Muffel seitlich befestigten Gitter Teleskopschienen mit jeweils einem stationären und einem oder mehreren beweglichen Schienenelementen, die in Längsrichtung relativ zu der stationären Schiene und aus dem Ofen heraus verfahrbar gelagert sind, vorgesehen. Ein genereller Vorteil von Teleskopschienen gegenüber der Lagerung des Gargutträgers in Nuten oder auf Drähten eines Gitters ist ihre Leichtgängigkeit und die Stabilität und Sicherheit gegen ein Abkippen des Gargutträgers in der ausgezogenen Stellung.Food support in ovens are known in many forms and are constantly evolving and improving. In simple known ovens the food support is guided in grooves which are formed in different heights or levels in the muffle side wall. The sliding behavior of the food support in such grooves depends on the surface texture of the surfaces sliding on each other and the load of the food support and is relatively poor. In other known systems instead of the grooves on the muffle side walls grid with horizontal bars or wires are fixed with a generally round cross-section, on which the food supports are carried and guided. Due to the smaller contact surface, the sliding behavior is slightly improved compared to grooves. Both systems have the disadvantage that the food support can only be pulled out of the oven to a certain extent, without having to tilt down or support the front. In the case of improved and higher-value ovens, telescopic rails are provided on the muffle side wall or on a grid fastened laterally in the muffle, each having one stationary and one or more movable rail elements which are movably mounted longitudinally relative to the stationary rail and out of the oven. A general advantage of telescopic rails over the storage of the food support in grooves or on wires of a grid is their ease and stability and security against tipping of the food support in the extended position.

Die Befestigung der Teleskopschienen an der Muffelseitenwand oder an einem in der Muffel seitlich befestigten Gitter kann auf verschiedene Weisen erfolgen. Für eine dauerhafte und preiswert herzustellende Befestigung werden je nach Ausführung 1 bis 3 Teleskopschienen an dem Gitter angeschweißt. Da meist der Hersteller der Gitter nicht der gleiche ist wie der Hersteller der Teleskopschienen, werden die Teile im Fertigungsprozess von einem Hersteller zum anderen transportiert, z. B. wird das zu schweißende Schienenelement vom Hersteller der Teleskopschienen an den Gitterhersteller geschickt, wo das Schienenelement an das Gitter angeschweißt und zum Schutz vor Korrosion üblicherweise verchromt wird. Anschließend wird das Gitter wieder an den Hersteller der Teleskopschienen geschickt, wo dann die Endmontage der Teleskopschienen erfolgt. Dies ist aufwendig und verursacht hohe Transportkosten.The attachment of the telescopic rails on the muffle side wall or on a laterally mounted in the muffle grid can be done in various ways. Depending on the model, 1 to 3 telescopic rails are welded to the grid for a permanent and reasonably priced mounting. Since most of the manufacturers of the grid is not the same as the manufacturer of the telescopic rails, The parts are transported in the manufacturing process from one manufacturer to another, eg. For example, the rail element to be welded is sent by the manufacturer of the telescopic rails to the lattice manufacturer, where the rail element is welded to the lattice and is usually chrome plated for protection against corrosion. Then the grid is sent back to the manufacturer of the telescopic rails, where then the final assembly of the telescopic rails. This is expensive and causes high transport costs.

Eine flexiblere Lösung bieten verschiedene Clip- und Steckmontagesysteme, die es erlauben, die fertige Teleskopschiene mehr oder weniger einfach an dem Gitter zu befestigen und auch wieder von diesem zu entfernen. Ein Vorteil dieser Systeme ist, dass die Teleskopschienen in beliebiger Höhe an dem Gitter montiert werden können und die Anzahl der montierten Teleskopschienen frei gewählt werden kann. Die bekannten Clip- und Steckmontagesysteme erfordern jedoch häufig zusätzlich zu den Schienenelementen weitere Montageelemente für die Befestigung der Schiene an dem Gitter. Diese Montageelemente werden nach dem Formen des Schienenelementes, welches als stationäres Schienenelement für die Festlegung an dem Gitter vorgesehen ist, an dessen Rückseite durch Anschweißen oder Anschrauben befestigt. Das Vorsehen solcher Montageelemente an der Schiene erfordert zusätzliches Material und Herstellungsaufwand und erhöht damit die Kosten für die Teleskopschiene. Zudem benötigen die meisten dieser bekannten Clip- und Steckmontagesysteme wenigstens zwei parallel angeordnete Gitterstäbe für die Befestigung der Schiene über die Montageelemente an dem Gitter, da die Montageelemente häufig die zwei Gitterstäbe umgreifen oder sich an wenigstens einem der Gitterstäbe abstützen müssen, um ein Verkippen der Schiene im montierten Zustand zu verhindern.A more flexible solution is offered by various clip and plug-in mounting systems, which allow the finished telescopic rail to be more or less easily attached to and removed from the grille. An advantage of these systems is that the telescopic rails can be mounted at any height on the grid and the number of mounted telescopic rails can be freely selected. However, the known clip and Steckmontagesysteme often require in addition to the rail elements further mounting elements for attaching the rail to the grid. These mounting elements are attached to the back by welding or screwing after molding the rail element, which is provided as a stationary rail element for attachment to the grid. The provision of such mounting elements on the rail requires additional material and manufacturing costs and thus increases the cost of the telescopic rail. In addition, most of these known clip and plug-in mounting systems require at least two parallel bars for mounting the rail on the mounting elements on the grid, since the mounting elements often surround the two bars or must be supported on at least one of the bars to a tilting of the rail to prevent in the assembled state.

Die DE 20 2008 000 887 U1 beschreibt ein Montagesystem zur Befestigung eines Schienenelementes einer Teleskopschiene an zwei in einem vorgegebenen Abstand parallel zueinander und im wesentlichen senkrecht zur Längserstreckung des Schienenelementes angeordneten Gitterstäben eines Gitters in einem Backofen, wobei von der Rückenfläche des Schienenelementes, welche den Gitterstäben zugewandt ist und an diesen anliegt, wenigstens zwei aus dem Material des Schienenelementes ausgestanzte oder daran befestigte Materialabschnitte aus der Ebene der Rückenfläche hervortreten, wobei einer oder beide der ausgestanzten Materialabschnitte zu Haken mit einem im wesentlichen parallel oder schräg zur Ebene der Rückenfläche verlaufenden Abschnitt gekröpft sind. Dabei kann einer der Materialabschnitte nicht zu einem Haken gekröpft sein und als Lasche im wesentlichen senkrecht von der Ebene der Rückenfläche abstehen.The DE 20 2008 000 887 U1 describes a mounting system for fastening a rail element of a telescopic rail to two at a predetermined distance parallel to each other and substantially perpendicular to the longitudinal extent of the rail element arranged bars of a grid in an oven, wherein from the back surface of the rail element which faces the grid bars and abuts against these at least two material sections punched out of or attached to the material of the rail element protrude from the plane of the back surface, wherein one or both of the stamped material sections are crimped to hooks having a section extending substantially parallel or oblique to the plane of the back surface. In this case, one of the material sections can not be bent to a hook and protrude as a tab substantially perpendicularly from the plane of the back surface.

Die DE 202005013789 U1 beschreibt ein Schnellbefestigungssystem zur Montage eines Schienenelements an paarweise in einem vorgegebenen Abstand parallel übereinander angeordneten Gitterstäben, wobei einer oder beide der Gitterstäbe elastisch sind und sich daher zeitweilig auseinanderbiegen lassen. Das zu befestigende Schienenelement weist wenigstens ein Montageelement auf mit einem oberen Halteabschnitt, der den oberen Gitterstab von oben teilweise umgreift, und mit einem unteren Halteabschnitt, der den zugehörigen unteren Gitterstab des Paares von Gitterstäben von unten teilweise umgreift. Dabei wird zwischen den Gitterstäben und dem Schnellbefestigungselement eine form- und kraftschlüssige Verbindung ausgebildet. Der obere und der untere Halteabschnitt des Schnellbefestigungselementes stehen bezüglich ihres vertikalen Abstandes in einer starren Beziehung zueinander.The DE 202005013789 U1 describes a quick-fastening system for mounting a rail element in pairs at a predetermined distance parallel superimposed bars, wherein one or both of the bars are elastic and therefore can be bent apart temporarily. The rail element to be fastened has at least one mounting element on with an upper holding portion which engages around the upper lattice bar from above partially, and with a lower holding portion, which partially surrounds the associated lower lattice bar of the pair of bars from below. In this case, a positive and non-positive connection is formed between the bars and the quick-fastening element. The upper and lower holding portions of the quick-fastening element are in a rigid relation to each other with respect to their vertical spacing.

Die DE 20010037 U1 beschreibt ein Schnellbefestigungselement zur Montage eines Schienenelements an paarweise in einem vorgegebenen Abstand parallel übereinander angeordneten Gitterstäben, wobei das Schnellbefestigungselement einen oberen Halteabschnitt aufweist, der den oberen Gitterstab teilweise umgreift, und einen unteren Halteabschnitt, der den unteren Gitterstab teilweise umgreift, sowie eine Nase zwischen dem oberen und dem unteren Halteabschnitt, die an dem unteren Gitterstab anliegt. Das Schnellbefestigungselement ist aus einem biegbaren Material gebildet, damit die Halteabschnitte für das Umgreifen der Gitterstäbe elastisch auseinandergebogen werden können. Die Nase zwischen dem oberen und dem unteren Halteabschnitt ist dafür vorgesehen, dass sie auf der dem unteren Halteabschnitt gegenüberliegenden Seite des unteren Gitterstabs an diesem anliegt und dadurch den Abstand zwischen den beiden Gitterstäben auch bei einer erheblichen vertikalen Belastung gleich hält. Dadurch soll verhindert werden, dass sich die Gitterstäbe voneinander entfernen und womöglich das Schnellbefestigungselement lösen. Des weiteren soll eine Last an dem Schnellbefestigungselement auf beide Gitterstäbe gleichmäßig verteilt werden.The DE 20010037 U1 describes a quick fastener for mounting a rail member to pairs in a predetermined distance parallel superimposed bars, wherein the quick fastener has an upper holding portion which engages around the upper bar partially, and a lower holding portion which engages around the lower bar partially, and a nose between the upper and lower holding portions, which abuts against the lower grid bar. The quick-fastening element is formed of a bendable material, so that the holding portions for embracing the bars can be elastically bent apart. The nose between the upper and the lower holding portion is provided so that it rests on the opposite side of the lower lattice member to the lower holding portion and thereby keeps the same distance between the two bars, even at a considerable vertical load. This is to prevent the bars from moving apart and possibly releasing the quick fastener. Furthermore, a load on the quick fastener is to be evenly distributed to both bars.

Beschreibung der ErfindungDescription of the invention

Gelöst wird diese Aufgabe erfindungsgemäß durch ein Schienenmontagesystem zur Befestigung eines Schienenelementes einer Teleskopschiene an einem in Längsrichtung des Schienenelementes angeordneten Draht, insbesondere einem Gitterdraht eines Gitters zur Befestigung von Gargutträgerführungen in einem Backofen, wobei an der Rückenfläche des Schienenelementes in dessen Längserstreckung in der Richtung von dem vorderen Ende des Schienenelementes in Auszugsrichtung der Teleskopschiene zu dem hinteren Ende in Einschubrichtung der Teleskopschiene eine erste Anordnung mit wenigstens einem Haken und in einem Abstand dazu eine zweite Anordnung mit wenigstens zwei Haken vorgesehen sind,
wobei die Haken für das Umgreifen eines in Längsrichtung des Schienenelementes angeordneten Drahtes jeweils einen im wesentlichen senkrecht von der Ebene der Rückenfläche hervorstehenden und einen sich daran anschließenden, im wesentlichen parallel zur Ebene der Rückenfläche und senkrecht zur Längsrichtung des Schienenelementes erstreckenden Abschnitt aufweisen und
wobei zwei Haken der zweiten Anordnung in einem Abstand und zueinander in entgegengesetzter Richtung orientiert angeordnet sind.This object is achieved according to the invention by a rail mounting system for fastening a rail element of a telescopic rail to a arranged in the longitudinal direction of the rail element wire, in particular a grid wire of a grid for fixing Gargutträgerführungen in an oven, wherein on the back surface of the rail element in the longitudinal extent in the direction of the front end of the rail element in the extension direction of the telescopic rail to the rear end in the direction of insertion of the telescopic rail, a first arrangement with at least a hook and at a distance to a second arrangement are provided with at least two hooks,
wherein the hooks for embracing a wire arranged in the longitudinal direction of the rail element each have a section extending substantially perpendicularly from the plane of the back surface and adjoining, substantially parallel to the plane of the back surface and perpendicular to the longitudinal direction of the rail element
wherein two hooks of the second arrangement are arranged at a distance and oriented towards each other in the opposite direction.

Für die Montage der Teleskopschiene an dem Draht wird die Rückseite des Schienenelementes der Teleskopschiene in einem Winkel gegenüber dem Draht an den Draht herangeführt, bis der Draht zwischen den entgegengesetzt orientierten Haken der zweiten Anordnung anliegt. Dann wird die Teleskopschiene in Richtung des Drahtes verkippt bis in eine Stellung im wesentlichen parallel zu dem Draht und noch ein kurzes Stück darüber hinaus, so dass die Haken der ersten Anordnung über den Draht geführt und in diesen in wiederum entgegengesetzter Bewegungsrichtung eingehakt werden können. Gleichzeitig umgreifen die Haken der zweiten Anordnung den Draht. Die Demontage der Teleskopschiene erfolgt in umgekehrter Abfolge.For the mounting of the telescopic rail to the wire, the back of the rail member of the telescopic rail at an angle relative to the wire is brought to the wire until the wire rests between the oppositely oriented hook of the second arrangement. Then, the telescopic rail is tilted in the direction of the wire to a position substantially parallel to the wire and a short distance beyond, so that the hooks of the first arrangement can be guided over the wire and hooked into these in turn opposite direction of movement. At the same time, the hooks of the second arrangement embrace the wire. The disassembly of the telescopic rail is done in reverse order.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Schienenmontagesystems weist die erste Anordnung einen Haken oder zwei Haken, die in einem Abstand zueinander und in gleicher Richtung orientiert angeordnet sind, auf, und die zweite Anordnung mit wenigstens zwei Haken ist in einem Abstand dazu angeordnet.In a preferred embodiment of the rail mounting system according to the invention, the first arrangement has a hook or two hooks which are arranged at a distance from one another and oriented in the same direction, and the second arrangement with at least two hooks is arranged at a distance therefrom.

In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Schienenmontagesystems sind die Haken aus dem Material des Schienenelementes ausgestanzt und ausgebogen. Hierfür werden bei der Herstellung des Schienenelementes für jeden Haken drei Seiten einer Lasche ausgestanzt und diese anschließend zunächst senkrecht von der Ebene der Rückenfläche ausgebogen und anschließend in einem Abstand von der Rückenfläche des Schienenelementes weiter parallel zur Ebene der Rückenfläche und senkrecht zur Längsrichtung des Schienenelementes umgebogen. Die Haken an dem Schienenelement lassen sich auf diese Weise bei der Fertigung der Schienenelemente, die üblicherweise aus Stahlband, sogenanntem Coil-Material, produziert werden, ohne zusätzlichen Materialaufwand einfach im laufenden Herstellungsprozess ausbilden, wodurch Herstellungsaufwand und Material und damit Kosten gegenüber der Herstellung der Haken als separate Bauteile und die anschließende Anbringung eingespart werden.In a further preferred embodiment of the rail mounting system according to the invention, the hooks are punched out of the material of the rail element and bent out. For this purpose, in the production of the rail element for each hook three sides of a tab punched and then first bent outwardly from the plane of the back surface and then bent at a distance from the back surface of the rail element parallel to the plane of the back surface and perpendicular to the longitudinal direction of the rail element. The hooks on the rail element can be in this way in the production of rail elements, which are usually made of steel strip, so-called coil material produced without additional material costs easily in the current manufacturing process, thereby manufacturing cost and material and thus costs compared to the production of hooks be saved as separate components and the subsequent attachment.

In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Schienenmontagesystems weist das Schienenelement wenigstens eine Drahtaufnahmeprägung auf, die als eine sich in Längsrichtung des Schienenelementes erstreckende Vertiefung in der Rückenfläche des Schienenelementes ausgebildet ist. Die Drahtaufnahmeprägung ist dafür vorgesehen, dass der Draht in den Abschnitten des Schienenelementes, in denen der Draht bei der Montage der Schiene mit dem Schienenelement in Kontakt kommt, bis zu einer durch die Form der Drahtaufnahmeprägung vorgegebenen Tiefe in die Rückenfläche des Schienenelementes eintritt. Die Drahtaufnahmeprägung bzw. die Drahtaufnahmeprägungen erstreckt bzw. erstreckten sich in der Rückenfläche des Schienenelementes wenigstens in den Abschnitten, in denen der Draht mit der Rückenfläche des Schienenelementes in Kontakt kommt und wenigstens in den Abschnitten, in denen die Haken für die Befestigung des Schienenelementes an dem Draht angeordnet sind, d. h. in den Abschnitten der ersten und zweiten Anordnungen von Haken.In a further preferred embodiment of the rail mounting system according to the invention, the rail element has at least one wire receiving embossment, which is designed as a recess extending in the longitudinal direction of the rail element in the back surface of the rail element. The wire-receiving embossing is intended for the wire to enter the back surface of the rail element in the sections of the rail element in which the wire comes into contact with the rail element during assembly of the rail to a depth predetermined by the shape of the wire-receiving embossment. The wire receiving embossments extend in the back surface of the rail member at least in the portions where the wire contacts the back surface of the rail member and at least in the portions where the hooks for securing the rail member to the Wire are arranged, d. H. in the sections of the first and second arrangements of hooks.

Das Vorsehen der wenigstens einen Drahtaufnahmeprägung an dem Schienenelement hat mehrere Vorteile. Die wenigstens eine Drahtaufnahmeprägung kann so angeordnet sein, dass sie dem Benutzer bei der Montage der Schiene die Positionierung des Schienenelementes an dem Draht vorgibt und damit eine falsche oder ungünstige Positionierung verhindert.The provision of the at least one wire receiving embossment on the rail element has several advantages. The at least one wire-receiving embossing can be arranged so that it predetermines the positioning of the rail element on the wire during the installation of the rail, thus preventing incorrect or unfavorable positioning.

Des Weiteren trägt die Drahtaufnahmeprägung zur besseren Befestigung des Schienenelementes an dem Draht bei. Bei der Montage wird der Draht zwischen den freien Enden der Haken und der Rückenfläche des Schienenelementes hindurchgeführt und taucht bzw. rastet in der Endlage in die Drahtaufnahmeprägung ein, so dass eine clipartige oder bajonettartige Befestigung zustande kommt.Furthermore, the wire-receiving embossing contributes to the better attachment of the rail element to the wire. During assembly, the wire is passed between the free ends of the hook and the back surface of the rail element and dives or snaps into the end position in the wire receiving embossing, so that a clip-like or bayonet-type attachment comes about.

Ein Weiterer Vorteil der als Vertiefung ausgebildeten Drahtaufnahmeprägung besteht darin, dass die Haken nicht so weit von der Rückenfläche des Schienenelementes abstehen müssen wie bei einer Ausführung ohne Drahtaufnahmeprägung, da der Abstand der von den Haken zu umgreifenden Seite des Drahtes von der Rückenfläche des Schienenelementes durch das Eintauchen des Drahtes in die Drahtaufnahmeprägung geringer wird. Dies ist bei Schienenelementen mit geringer Höhe von besonderem Vorteil, da bei diesen Schienenelementen aufgrund der geringen Höhe die Länge der durch Ausstanzen der Haken aus dem Material der Rückenfläche begrenzt ist.Another advantage of the trained as a recess wire receiving embossing is that the hooks do not have to protrude so far from the back surface of the rail element as in a version without wire receiving embossing, since the distance of the hooks to be gripped side of the wire from the back surface of the rail element through the Dipping the wire in the wire receiving embossing is less. This is particularly advantageous for rail elements with a low height, since the length of the latter is limited by punching out the hooks from the material of the back surface due to the low height of these rail elements.

In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Schienenmontagesystems umfasst das System ein Gitter, vorzugsweise ein Seitengitter eines Backofens, mit wenigstens einem Draht zur Befestigung des Schienenelementes einer Teleskopschiene.In a further preferred embodiment of the rail mounting system according to the invention, the system comprises a grid, preferably a side rail of a baking oven, with at least one wire for fastening the rail element of a telescopic rail.

In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Schienenmontagesystems weist der wenigstens eine Draht auf der der Rückenfläche des Schienenelementes abgewandten Seite wenigstens in den Abschnitten, in denen die Haken den Draht umgreifen, Abflachungen, vorzugsweise geprägte Abflachungen auf, an denen die Innenflächen der Haken formschlüssig zu Anlage kommen, wenn das Schienenelement an dem Draht montiert ist. Hierdurch wird ein Verkippen der Teleskopschiene um die Achse des Drahtes verhindert.In a further preferred embodiment of the rail mounting system according to the invention, the at least one wire on the side facing away from the back surface of the rail element at least in the sections in which the hook engage around the wire, flats, preferably embossed flats on which the inner surfaces of the hook form-fit to plant come when the rail element is mounted on the wire. This prevents tilting of the telescopic rail about the axis of the wire.

In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Schienenmontagesystems weist der wenigstens eine Draht auf der der Rückenfläche des Schienenelementes zugewandten Seite Abstützprägungen auf, die sich im wesentlichen parallel zu der Rückenfläche des Schienenelements erstrecken und an denen die Rückenfläche des Schienenelements zu Anlage kommt, wenn das Schienenelement an dem Draht montiert ist. Auch hierdurch wird ein Verkippen der Teleskopschiene um die Achse des Drahtes verhindert.In a further preferred embodiment of the rail mounting system according to the invention, the at least one wire on the back surface of the rail element side facing Abstützprägungen extending substantially parallel to the back surface of the rail element and where the back surface of the rail element comes to rest when the rail element the wire is mounted. This also prevents tilting of the telescopic rail about the axis of the wire.
