Definitions

  • the invention relates to a locking arrangement for an opening in a cabinet, a refrigerator, a building and the like according to the features of the preamble of claim 1.
  • This closure arrangement has a first and a second cover part, of which at least one cover part is designed to be movable and wherein the cover parts lie in one plane in the closed state.
  • the movable cover part is guided by rollers that run in one or more roller conveyors. This is intended to reduce the friction when moving a cover part and to enable optimal sealing and precise cover guidance.
  • the closure arrangements are designed in such a way that they can be operated manually by the user, in that the respective cover part to be opened can be moved by hand from a closed position to an open position.
  • a disadvantage of this closure arrangement for cooling devices is that the manual movement of the cover parts from a closed position to an open position allows the goods in the cooling device to be removed, but very high displacement forces occur for the closure elements during the movement due to the rollers used , which make it difficult for the user to move the individual cover parts of the closure arrangement simply or easily.
  • a further disadvantage of the closure arrangement according to the prior art is seen in the fact that the movement of the cover parts is improved through the use of rollers mounted with ball bearings increase the costs of such a cooling device without the displacement forces for locking elements being significantly reduced.
  • roller conveyors can become soiled by dust or fine-grained materials such as sugar, salt and the like getting into them and leading to an increase in the displacement forces for closure elements up to the blocking of the rollers.
  • cooling devices Another disadvantage of the cooling devices is that, in order to fill the shelves positioned behind or above them, the personnel stand on the closure arrangement and place a great deal of weight on it. Due to the weight of the people and the goods on the locking arrangements, the rollers are exposed to very high forces, which on the one hand can lead to damage or impairment of the rollers or roller tracks and on the other hand to damage to the cover parts and a risk of accidents for the staff themselves .
  • a locking arrangement for cabinet furniture is in the DE 29907856 U1 disclosed.
  • a locking arrangement is described for receiving sliding and sliding elements, such as blinds, shutters or sliding doors, in at least one U-rail-shaped conductor track on furniture with a base profile that can be fastened to the furniture body and a cover profile that can be connected to this to cover the fastening of the base profile on the Furniture body.
  • This locking arrangement for generic cupboard furniture should be able to be manufactured inexpensively and be adaptable in a simple manner to the respective application and thus basically allow an option for receiving various sliding or sliding elements.
  • This is to be achieved in that the slide is formed in a separate rail element which is detachably inserted in a recess in the base profile.
  • the base profile can have a front and a further rear recess.
  • a disadvantage of this guide device for cabinet furniture is that the provision of a base profile and a cover profile and an additional rail element leads to high manufacturing and assembly costs, as well as to a considerable logistic effort in storage. This particular under the fact that various Cabinet dimensions in different decors must be equipped with such guide devices.
  • this locking arrangement can only be mounted on cabinet furniture in which the sliding and sliding elements can be moved in front of the body of the cabinet.
  • sliding and sliding elements such as blinds or shutters, which should be movable within the body of the cabinet, these locking arrangements cannot be used.
  • Another disadvantage of the prior art is that, especially when using sliding and sliding elements such as blinds or shutters with the locking arrangement, certain deflection elements must be installed in which these sliding and sliding elements must be accommodated inside the cabinet, such as guide screws or .Angled elements.
  • a high level of assembly and manufacturing effort has to be implemented in order to adapt the guide device to the corresponding sliding and sliding elements as well as to the body of the cabinet. This applies to both the base profile and the cover profile as well as the rail elements to be used separately and also end pieces to be inserted at the free ends of the guide device.
  • Another disadvantage is that the forces for moving the sliding and sliding elements in the locking arrangement are very high and, due to the abrasion of the individual elements or due to contamination due to lubricant in the guide rails, have the same disadvantages as the locking arrangements in cooling devices .
  • the EP 2042550 A discloses a lubricious material which is obtainable by extrusion of a raw material comprising an olefin-based polymer and a silicone compound as essential components, wherein a part of the olefin-based polymer in the lubricious material forms a crosslinked material, the crosslinked material domains for dispersion in the lubricious material, in order to prevent uneven distribution of the silicone compound in the extrusion direction, the residual fraction in the hot xylene reflux of the lubricious material is in a range of 33 to 75 percent by weight based on the total weight of the lubricious material, the content of the silicone compound based of the total weight of the lubricious material is in a range from 5 to 20 percent by weight and the mean particle diameter of the domains on the cross section parallel to the extrusion direction is in a range from 0.5 to 150 ⁇ m.

This advantageously means that migration of the component (K) from the individual elements of the closure arrangement according to the invention is almost impossible.
  • component (K) has a molecular weight of about 200 to 600,000 g / mol.
  • This advantageous embodiment makes it possible to design both the profile elements and the guide elements in such a way that the required displacement forces of the closure arrangement according to the invention are very low.
  • component (K) has a molecular weight of about 100,000 to 600,000 g / mol, in particular from about 300,000 to 600,000 g / mol.
  • the profile elements, the guide elements, the sealing elements and the sliding elements are designed in such a way that the displacement forces of the closure arrangement according to the invention are even lower and their production costs are also lower.
  • the material of the profile element and / or the guide element has a coefficient of sliding friction ⁇ according to DIN EN ISO 8295 of 0.01 to 0.06, preferably 0.02 to 0.05 for smooth surfaces.

Description

Die Erfindung betrifft eine Verschlussanordnung für eine Öffnung eines Schrankmöbels, eines Kühlgerätes, eines Gebäudes und dergleichen gemäß den Merkmalen des Obergriffes des Anspruches 1.The invention relates to a locking arrangement for an opening in a cabinet, a refrigerator, a building and the like according to the features of the preamble of claim 1.

Derartige Verschlussanordnungen sind im Stand der Technik bereits bekannt.Such closure arrangements are already known in the prior art.

So offenbart die DE 102009016208 A1 eine Verschlussanordnung für Kühlgeräte. Diese Verschlussanordnung weist einen ersten und einen zweiten Deckelteil auf, von denen wenigstens ein Deckelteil bewegbar ausgeführt ist und wobei die Deckelteile im geschlossenen Zustand in einer Ebene liegen.
Bei diesem Schiebedeckelsystem ist die Führung des bewegbaren Deckelteils über Rollen realisiert, die in einer oder mehrerer Rollenbahnen laufen. Dadurch soll die Reibung beim Bewegen eines Deckelteils verringert werden und die Möglichkeit einer optimalen Abdichtung sowie eine präzise Deckelführung möglich sein.
Die Verschlussanordnungen sind so ausgelegt, dass diese manuell durch den Benutzer zu bedienen sind, indem der jeweils zu öffnende Deckelteil von Hand von einer Geschlossenstellung in eine Offenstellung bewegbar ist.So reveals the DE 102009016208 A1 a locking arrangement for cooling devices. This closure arrangement has a first and a second cover part, of which at least one cover part is designed to be movable and wherein the cover parts lie in one plane in the closed state.
In this sliding cover system, the movable cover part is guided by rollers that run in one or more roller conveyors. This is intended to reduce the friction when moving a cover part and to enable optimal sealing and precise cover guidance.
The closure arrangements are designed in such a way that they can be operated manually by the user, in that the respective cover part to be opened can be moved by hand from a closed position to an open position.

Nachteilig bei dieser Verschlussanordnung für Kühlgeräte wird gesehen, dass durch die manuelle Bewegung der Deckelteile von einer Geschlossenstellung in eine Offenstellung die in dem Kühlgerät befindlichen Waren zwar entnommen werden können, dass aber bei der Bewegung bedingt durch die verwendeten Rollen sehr hohe Verschiebekräfte für die Verschlusselemente auftreten, die es dem Nutzer erschweren, die einzelnen Deckelteile der Verschlussanordnung einfach bzw. leicht zu bewegen.A disadvantage of this closure arrangement for cooling devices is that the manual movement of the cover parts from a closed position to an open position allows the goods in the cooling device to be removed, but very high displacement forces occur for the closure elements during the movement due to the rollers used , which make it difficult for the user to move the individual cover parts of the closure arrangement simply or easily.

Ein weiterer Nachteil der Verschlussanordnung nach dem Stand der Technik wird darin gesehen, dass eine Verbesserung der Bewegung der Deckelteile durch die Verwendung von mit Kugellagern gelagerten Rollen die Kosten eines derartigen Kühlgerätes erhöhen, ohne dass die Verschiebekräfte für Verschlusselemente entscheidend reduziert sind.A further disadvantage of the closure arrangement according to the prior art is seen in the fact that the movement of the cover parts is improved through the use of rollers mounted with ball bearings increase the costs of such a cooling device without the displacement forces for locking elements being significantly reduced.

Weiterhin nachteilig wird gesehen, dass bei längerem Gebrauch die Rollenbahnen verschmutzen können, indem Staub oder auch feinkörnige Materialien wie beispielsweise Zucker, Salz und dergleichen in diese hineinkommen und zu einer Erhöhung der Verschiebekräfte für Verschlusselemente führen bis hin zum Blockieren der Rollen.Another disadvantage is that with prolonged use, the roller conveyors can become soiled by dust or fine-grained materials such as sugar, salt and the like getting into them and leading to an increase in the displacement forces for closure elements up to the blocking of the rollers.

Ebenfalls nachteilig bei den Kühlgeräten ist, dass zum Befüllen der dahinter oder darüber positionierten Regale sich das Personal auf die Verschlussanordnung stellt und diese mit einem hohem Gewicht belasten. Durch das Gewicht der Personen und der Ware auf den Verschlussanordnungen werden die Rollen sehr hohen Kräften ausgesetzt, was einerseits zu einer Beschädigung oder Beeinträchtigung der Rollen bzw. der Rollenbahnen und andererseits auch zu einer Beschädigung der Deckelteile sowie zu einer Unfallgefahr für das Personal selbst führen kann.Another disadvantage of the cooling devices is that, in order to fill the shelves positioned behind or above them, the personnel stand on the closure arrangement and place a great deal of weight on it. Due to the weight of the people and the goods on the locking arrangements, the rollers are exposed to very high forces, which on the one hand can lead to damage or impairment of the rollers or roller tracks and on the other hand to damage to the cover parts and a risk of accidents for the staff themselves .

Eine weitere Verschlussanordnung für Schrankmöbel ist in der DE 29907856 U1 offenbart. Es wird eine Verschlussanordnung beschrieben, zur Aufnahme von Gleit- und Schiebeelementen, wie beispielsweise Jalousien, Rollläden oder Schiebetüren, in zumindest einer U-schienenförmigen Leitbahn an Möbeln mit einem am Möbelkorpus befestigbaren Basisprofil und einem mit diesem verbindbaren Abdeckprofil zur Abdeckung der Befestigung des Basisprofils am Möbelkorpus.
Diese Verschlussanordnung für gattungsgemäße Schrankmöbel soll preisgünstig hergestellt werden können, sowie auf einfache Weise an den jeweiligen Einsatzzweck anpassbar sein und somit grundsätzlich eine Option zur Aufnahme verschiedener Gleit- oder Schiebeelemente ermöglichen. Realisiert werden soll dies dadurch, dass die Gleitbahn in einem separaten Schienenelement ausgebildet ist, das lösbar in einer Ausnehmung des Basisprofils eingesetzt ist. Das Basisprofil kann dabei eine vordere und eine weitere hintere Ausnehmung aufweisen.Another locking arrangement for cabinet furniture is in the DE 29907856 U1 disclosed. A locking arrangement is described for receiving sliding and sliding elements, such as blinds, shutters or sliding doors, in at least one U-rail-shaped conductor track on furniture with a base profile that can be fastened to the furniture body and a cover profile that can be connected to this to cover the fastening of the base profile on the Furniture body.
This locking arrangement for generic cupboard furniture should be able to be manufactured inexpensively and be adaptable in a simple manner to the respective application and thus basically allow an option for receiving various sliding or sliding elements. This is to be achieved in that the slide is formed in a separate rail element which is detachably inserted in a recess in the base profile. The base profile can have a front and a further rear recess.

Nachteilig bei dieser Führungsvorrichtung für Schrankmöbel wird gesehen, dass die Bereitstellung eines Basisprofils sowie eines Abdeckprofils und eines zusätzlichen Schienenelementes zu hohen Herstellungs- und Montagekosten, sowie zu einem beträchtlichen Logistikaufwand in der Lagerhaltung führt. Dies insbesondere unter der Tatsache, dass verschiedene Schrankabmessungen in verschiedenen Dekoren mit derartigen Führungsvorrichtungen bestückt werden müssen.A disadvantage of this guide device for cabinet furniture is that the provision of a base profile and a cover profile and an additional rail element leads to high manufacturing and assembly costs, as well as to a considerable logistic effort in storage. This particular under the fact that various Cabinet dimensions in different decors must be equipped with such guide devices.

Ein weiterer Nachteil wird darin gesehen, dass das Basisprofil und das diesem zugeordnete Schienenelement jeweils nur für eine definierte Breite von Gleit- und Schiebeelementen einsetzbar ist.Another disadvantage is seen in the fact that the base profile and the rail element assigned to it can only be used for a defined width of sliding and sliding elements.

Diese Verschlussanordnung kann nachteiligerweise auch nur an solche Schrankmöbel montiert werden, bei denen die Gleit- und Schiebeelemente vor dem Korpus des Schrankmöbels bewegbar sind. Beim Einbau von Gleit- und Schiebeelementen wie beispielsweise Jalousien bzw. Rollläden, welche innerhalb der Korpen des Schrankmöbels bewegbar sein sollen, sind diese Verschlussanordnungen nicht einsetzbar.Disadvantageously, this locking arrangement can only be mounted on cabinet furniture in which the sliding and sliding elements can be moved in front of the body of the cabinet. When installing sliding and sliding elements such as blinds or shutters, which should be movable within the body of the cabinet, these locking arrangements cannot be used.

Weiterhin nachteilig beim Stand der Technik wird gesehen, dass insbesondere beim Einsatz von Gleit- und Schiebeelementen wie beispielsweise Jalousien bzw. Rollläden mit der Verschlussanordnung bestimmte Umlenkelemente montiert werden müssen, in denen diese Gleit- und Schiebeelemente im Schrankinneren aufgenommen werden müssen, wie beispielsweise Führungsschnecken bzw. Winkelelemente.
Beim Einsatz der Verschlussanordnung gemäß dem Stand der Technik ist hier ein hoher Montage- und Konfektionsaufwand zu realisieren, um eine Anpassung der Führungsvorrichtung zu den entsprechenden Gleit- und Schiebeelementen sowie zum Korpus des Schrankmöbels zu realisieren. Dies betrifft sowohl das Basisprofil, als auch das Abdeckprofil sowie die separat einzusetzenden Schienenelemente und auch an den freien Enden der Führungsvorrichtung einzusetzende Endstücke.Another disadvantage of the prior art is that, especially when using sliding and sliding elements such as blinds or shutters with the locking arrangement, certain deflection elements must be installed in which these sliding and sliding elements must be accommodated inside the cabinet, such as guide screws or .Angled elements.
When using the locking arrangement according to the prior art, a high level of assembly and manufacturing effort has to be implemented in order to adapt the guide device to the corresponding sliding and sliding elements as well as to the body of the cabinet. This applies to both the base profile and the cover profile as well as the rail elements to be used separately and also end pieces to be inserted at the free ends of the guide device.

Ebenfalls nachteilig wird gesehen, dass die Kräfte zur Verschiebung der Gleit- und Schiebeelemente in der Verschlussanordnung sehr hoch sind und bedingt durch den Abrieb der einzelnen Elemente bzw. durch Verschmutzung bedingt durch Schmiermittel in den Führungsschienen, die gleichen Nachteile aufweisen, wie die Verschlussanordnungen bei Kühlgeräten.Another disadvantage is that the forces for moving the sliding and sliding elements in the locking arrangement are very high and, due to the abrasion of the individual elements or due to contamination due to lubricant in the guide rails, have the same disadvantages as the locking arrangements in cooling devices .

Die EP 2042550 A offenbart ein gleitfähiges Material, das durch Extrusion eines Rohstoffs erhältlich ist, der ein Polymer auf Olefingrundlage und eine Silikonverbindung als essenzielle Komponenten umfasst, wobei ein Teil des Polymers auf Olefingrundlage in dem gleitfähigen Material ein vernetztes Material bildet, das vernetzte Material Domänen zur Dispersion in dem gleitfähigen Material bildet, um eine ungleichmäßige Verteilung der Silikonverbindung in der Extrusionsrichtung zu verhindern, die Restfraktion beim heißen Xylolreflux des gleitfähigen Materials in einem Bereich von 33 bis 75 Gewichtsprozent auf der Grundlage des Gesamtgewichts des gleitfähigen Materials liegt, der Gehalt der Silikonverbindung auf Grundlage des Gesamtgewichts des gleitfähigen Materials in einem Bereich von 5 bis 20 Gewichtsprozent liegt und der mittlere Teilchendurchmesser der Domänen auf dem Querschnitt parallel zur Extrusionsrichtung in einem Bereich von 0,5 bis 150 µm liegt.The EP 2042550 A discloses a lubricious material which is obtainable by extrusion of a raw material comprising an olefin-based polymer and a silicone compound as essential components, wherein a part of the olefin-based polymer in the lubricious material forms a crosslinked material, the crosslinked material domains for dispersion in the lubricious material, in order to prevent uneven distribution of the silicone compound in the extrusion direction, the residual fraction in the hot xylene reflux of the lubricious material is in a range of 33 to 75 percent by weight based on the total weight of the lubricious material, the content of the silicone compound based of the total weight of the lubricious material is in a range from 5 to 20 percent by weight and the mean particle diameter of the domains on the cross section parallel to the extrusion direction is in a range from 0.5 to 150 μm.

Hier setzt die Erfindung ein, die sich die Aufgabe gestellt hat, die Nachteile des Standes der Technik zu überwinden und eine Verschlussanordnung aufzuzeigen, die wirtschaftlich und kostengünstig herstellbar ist, die eine geräuscharme, schnelle sowie schonende Schließbewegung der Verschlusselemente ermöglicht und die ohne zusätzliche Wartungsmaßnahmen eine lange Lebensdauer aufweist.This is where the invention comes in, which has set itself the task of overcoming the disadvantages of the prior art and showing a closure arrangement that can be produced economically and inexpensively, that enables a quiet, fast and gentle closing movement of the closure elements and that without additional maintenance measures has a long service life.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.According to the invention, this object is achieved by the features of claim 1. Further advantageous refinements of the invention are described in the subclaims.

Die erfindungsgemäße Verschlussanordnung für eine Öffnung eines Schrankmöbels, eines Kühlgerätes, eines Gebäudes und dergleichen mit wenigstens einem Verschlusselement, welches an der Öffnung bewegbar angeordnet ist, wobei wenigstens ein freies Ende des Verschlusselements wenigstens ein, mit einem Führungselement in Wirkverbindung stehendes Profilelement aufweist, wobei der Werkstoff des Profilelementes und / oder des Führungselementes 0,1 Gew.-% bis 30 Gew.-%, bezogen auf das Gesamtgewicht des Werkstoffes eine Komponente (K) aufweist, die der allgemeinen Formel R1R2R3Si-[O-Si R4R5]n-O-SiR6R7R8 entspricht, wobei R1 bis R8 gleich oder verschieden voneinander sind und ausgewählt sind aus der Gruppe bestehend aus Wasserstoffatomen und C1-C10-Alkylgruppen und wobei n einen Wert von 1 bis 8.000 aufweist zeichnet sich dadurch aus, dass der Werkstoff des Profilelementes und/oder des Führungselementes einen Gleitreibungskoeffizient µ von 0,01 bis 0,06 bevorzugt 0,02 bis 0,05 gemäß DIN EN ISO 8295 aufweist. Somit lassen sich erfindungsgemäße Verschlussanordnungen zur Verfügung stellen, die abhängig von der Größe bzw. dem Gewicht immer eine optimale und leichte Bewegung der Verschlussanordnung realisieren können. Hierdurch kann vorteilhafterweise erreicht werden, dass die erforderlichen Verschiebekräfte für die Verschlusselemente deutlich reduziert sind in einer Größenordnung von etwa 20 bis 95 %, bevorzugt 40 bis 80 %.The closure arrangement according to the invention for an opening of a cabinet, a refrigerator, a building and the like with at least one closure element which is movably arranged at the opening, wherein at least one free end of the closure element has at least one profile element that is operatively connected to a guide element, the The material of the profile element and / or the guide element has 0.1% by weight to 30% by weight, based on the total weight of the material, of a component (K) which has the general formula R 1 R 2 R 3 Si- [O- Si R 4 R 5 ] n —O — SiR 6 R 7 R 8 , where R 1 to R 8 are identical to or different from one another and are selected from the group consisting of hydrogen atoms and C 1 -C 10 -alkyl groups and where n is one Has a value of 1 to 8,000 is characterized in that the material of the profile element and / or the guide element has a coefficient of sliding friction μ of 0.01 to 0.06, preferably 0.02 to 0.05 according to DIN EN ISO 8295. Thus, closure arrangements according to the invention can be made available which, depending on the size or weight, can always implement an optimal and easy movement of the closure arrangement. In this way, it can advantageously be achieved that the required displacement forces for the closure elements are significantly reduced in an order of magnitude of approximately 20 to 95%, preferably 40 to 80%.

Ein weiterer Vorteil wird darin gesehen, dass die erfindungsgemäße Verschlussanordnung einen erheblich reduzierten Verschleiß der einzelnen Elemente aufweist. Weiterhin ist die erfindungsgemäße Verschlussanordnung so ausgebildet, dass R1 bis R8 in der allgemeinen Formel der Komponente (K) Methylgruppen (-CH3) aufweist. Dies führt vorteilhafterweise dazu, dass eine Migration der Komponente (K) aus den einzelnen Elementen der erfindungsgemäßen Verschlussanordnung nahezu ausgeschlossen ist.Another advantage is seen in the fact that the closure arrangement according to the invention has significantly reduced wear on the individual elements. Furthermore, the closure arrangement according to the invention is designed such that R 1 to R 8 in the general formula of component (K) have methyl groups (-CH 3 ). This advantageously means that migration of the component (K) from the individual elements of the closure arrangement according to the invention is almost impossible.

Es hat sich weiterhin als vorteilhaft herausgestellt, dass die Komponente (K) ein Molekulargewicht von etwa 200 bis 600.000 g / mol aufweist. Durch diese vorteilhafte Ausgestaltung ist es möglich, sowohl die Profilelemente als auch die Führungselemente so auszubilden, dass die erforderlichen Verschiebekräfte der erfindungsgemäßen Verschlussanordnung sehr gering sind. Ebenfalls vorteilhaft im Rahmen dieser Erfindung ist, dass die Komponente (K) ein Molekulargewicht von etwa 100.000 bis 600.000 g / mol, insbesondere von etwa 300.000 bis 600.000 g / mol aufweist. In dieser vorteilhaften Ausgestaltung sind die Profielemente, die Führungselemente, die Dichtelemente sowie die Gleitelemente so ausgebildet, dass die Verschiebekräfte der erfindungsgemäßen Verschlussanordnung nochmal geringer und auch deren Herstellungskosten niedriger sind.It has also been found to be advantageous that component (K) has a molecular weight of about 200 to 600,000 g / mol. This advantageous embodiment makes it possible to design both the profile elements and the guide elements in such a way that the required displacement forces of the closure arrangement according to the invention are very low. It is also advantageous in the context of this invention that component (K) has a molecular weight of about 100,000 to 600,000 g / mol, in particular from about 300,000 to 600,000 g / mol. In this advantageous embodiment, the profile elements, the guide elements, the sealing elements and the sliding elements are designed in such a way that the displacement forces of the closure arrangement according to the invention are even lower and their production costs are also lower.

Es hat sich ebenfalls als vorteilhaft herausgestellt, dass der Werkstoff des Profilelementes und / oder des Führungselementes einen Gleitreibungskoeffizient µ gemäß DIN EN ISO 8295 von 0,01 bis 0,06, bevorzugt 0,02 bis 0,05 bei glatten Oberflächen aufweist. Somit lassen sich erfindungsgemäße Verschlussanordnungen zur Verfügung stellen, die abhängig von der Größe bzw. dem Gewicht immer eine optimale und leichte Bewegung der Verschlussanordnung realisieren können.It has also been found to be advantageous that the material of the profile element and / or the guide element has a coefficient of sliding friction μ according to DIN EN ISO 8295 of 0.01 to 0.06, preferably 0.02 to 0.05 for smooth surfaces. Thus, closure arrangements according to the invention can be made available which, depending on the size or weight, can always implement an optimal and easy movement of the closure arrangement.

In einer weiteren vorteilhaften Ausgestaltung ist die erfindungsgemäße Verschlussanordnung so ausgebildet, dass der Werkstoff des Profilelementes und / oder des Führungselementes nach etwa 80.000 Reibungsbewegungen einen Gleitreibungskoeffizient µ gemäß DIN EN ISO 8295 von 0,01 bis 0,06, bevorzugt 0,02 bis 0,05 bei glatten Oberflächen aufweist. Die erfindungsgemäße Verschlussanordnung weist somit eine wesentlich höhere Verschleißfestigkeit gegenüber dem Stand der Technik auf und zeichnet sich weiterhin dadurch aus, dass sie ohne zusätzliche Wartungsmaßnahmen eine lange Lebensdauer aufweist, ohne dass sich der Gleitreibungskoeffizient µ wesentlich verändert.In a further advantageous embodiment, the closure arrangement according to the invention is designed in such a way that the material of the profile element and / or of the guide element has a sliding friction coefficient µ according to DIN EN ISO 8295 of 0.01 to 0.06, preferably 0.02 to 0, after approximately 80,000 frictional movements. 05 has smooth surfaces. The closure arrangement according to the invention thus has a significantly higher wear resistance compared to the prior art and is further characterized in that it has a long service life without additional maintenance measures, without the coefficient of sliding friction μ changing significantly.

Die erfindungsgemäße Verschlussanordnung zeichnet sich weiter dadurch aus, dass das Profilelement und / oder das Führungselement aus einem polymeren Werkstoff hergestellt ist. Unter polymerem Werkstoff sind Materialien gemeint, wie Polyvinylchlorid (PVC); Polyolefin, wie Polypropylen (PP) oder Polyethylen (PE); styrolbasiertes Polymer, wie Polystyrol (PS) oder Styrol-Butadien-Copolymer mit überwiegendem Styrolanteil (SB) oder Acrylnitril-Styrol-Acrylester-Copolymere (ASA) oder Acrylnitril-Butadien-Styrol-Copolymere (ABS) oder Styrolacrylnitril (SAN); Polybutylentherephthalat (PBT); Polyethylentherephthalat (PET); Polyoxymethylen (POM); Polyamid (PA); Polymethylmethacrylat (PMMA); Polyphenylenoxid (PPO); Polyetheretherketon (PEEK); Polyphenylensulfid (PPS); Liquid Crystal Polymer (LCP); Polyamidimide (PAI); Polyvinylidenfluorid (PVDF); Polyphenylsulfon (PPSU); Polyaryletherketon (PAEK); Polyacrylnitril (PAN); Polychlortrifluorethylen (PCTFE); Polyetherketon (PEK); Polyimid (PI); Polyisobuten (PIB); Polyphthalamid (PPA); Polypyrrol PPY);Polytetrafluorethylen (PTFE); Polyurethan (PUR); Polyvinylalkohol (PVA); Polyvinylacetat (PVAC); Polyvinylidenchlorid (PVDC); sowie Mischungen aus wenigstens zwei dieser Materialien. Dabei können dem polymeren Werkstoff des Profilelementes und/ des Führungselementes geeignete Füll- und / oder Verstärkungsstoffe beigemischt sein, die die mechanischen Eigenschaften positiv beeinflussen insbesondere Glasfasern, Glaskugeln aber auch Füllstoffe wie Kreide, Teflon und dergleichen. Die Füll- und / oder Verstärkungsstoffe sind dabei in Mengen von etwa 5 bis 50 Gew.-%, vorzugsweise 10 bis 35 Gew.-%, bezogen auf die Gesamtmasse, enthalten.The closure arrangement according to the invention is further characterized in that the profile element and / or the guide element is made from a polymer material. Polymeric material means materials such as polyvinyl chloride (PVC); Polyolefin such as polypropylene (PP) or polyethylene (PE); styrene-based polymer, such as polystyrene (PS) or styrene-butadiene copolymer with a predominant styrene content (SB) or acrylonitrile-styrene-acrylic ester copolymers (ASA) or acrylonitrile-butadiene-styrene copolymers (ABS) or styrene acrylonitrile (SAN); Polybutylene terephthalate (PBT); Polyethylene terephthalate (PET); Polyoxymethylene (POM); Polyamide (PA); Polymethyl methacrylate (PMMA); Polyphenylene oxide (PPO); Polyetheretherketone (PEEK); Polyphenylene sulfide (PPS); Liquid crystal polymer (LCP); Polyamide imides (PAI); Polyvinylidene fluoride (PVDF); Polyphenyl sulfone (PPSU); Polyaryletherketone (PAEK); Polyacrylonitrile (PAN); Polychlorotrifluoroethylene (PCTFE); Polyether ketone (PEK); Polyimide (PI); Polyisobutene (PIB); Polyphthalamide (PPA); Polypyrrole PPY); Polytetrafluoroethylene (PTFE); Polyurethane (PUR); Polyvinyl alcohol (PVA); Polyvinyl acetate (PVAC); Polyvinylidene chloride (PVDC); as well as mixtures of at least two of these materials. Suitable fillers and / or reinforcing materials can be added to the polymeric material of the profile element and / or the guide element, which have a positive effect on the mechanical properties, in particular glass fibers, glass spheres, but also fillers such as chalk, Teflon and the like. The fillers and / or reinforcing materials are contained in amounts of about 5 to 50% by weight, preferably 10 to 35% by weight, based on the total mass.

Die erfindungsgemäße Verschlussanordnung weist weiterhin am Profilelement und / oder am Führungselement wenigstens ein Distanzelement auf. Hierdurch ist es möglich, eine erfindungsgemäße Verschlussanordnung bereitzustellen, die neben einer vollflächigen Anlage der Verschlusselemente an den Führungselementen auch eine punktuelle Anlage mit noch weiter reduzierten Verschiebekräften für Verschlusselemente ermöglicht.The closure arrangement according to the invention also has at least one spacer element on the profile element and / or on the guide element. This makes it possible to provide a closure arrangement according to the invention which, in addition to full-surface contact of the closure elements on the guide elements, also enables punctual contact with even further reduced displacement forces for closure elements.

In einer weiteren vorteilhaften Ausgestaltungsform der erfindungsgemäßen Verschlussanordnung ist am Profilelement und / oder am Führungselement wenigstens ein Gleitelement angeordnet. Dieses führt vorteilhafterweise dazu, dass die für die Bewegung der Verschlusselemente erforderlichen Verschiebekräfte der erfindungsgemäßen Verschlussanordnung reduziert sind.In a further advantageous embodiment of the closure arrangement according to the invention, at least one sliding element is arranged on the profile element and / or on the guide element. This advantageously leads to the fact that the displacement forces of the closure arrangement according to the invention required for the movement of the closure elements are reduced.

Ein weiterer Vorteil der erfindungsgemäßen Verschlussanordnung wird darin gesehen, dass am Profilelement und / oder am Führungselement wenigstens ein Dichtelement angeordnet ist. Dies führt vorteilhafterweise dazu, dass beispielsweise beim Einsatz der Verschlussanordnung in einem Kühlgerät die gekühlte Luft im Innenraum nicht über die Verschlussanordnung in den warmen Verkaufsraum entweichen kann.Another advantage of the closure arrangement according to the invention is seen in the fact that at least one sealing element is arranged on the profile element and / or on the guide element. This advantageously leads to the fact that, for example, when the closure arrangement is used in a cooling device, the cooled air in the interior cannot escape via the closure arrangement into the warm sales area.

Es hat sich weiterhin als vorteilhaft herausgestellt, dass das Dichtelement einen Spalt zwischen dem Profilelement und dem Führungselement luftdicht und / oder flüssigkeitsdicht verschließt, was beispielsweise die Energiekosten beim Einsatz der erfindungsgemäßen Verschlussanordnung in einem Kühlgerät reduziert.It has also been found to be advantageous that the sealing element closes a gap between the profile element and the guide element in an airtight and / or liquid-tight manner, which, for example, reduces the energy costs when using the closure arrangement according to the invention in a cooling device.

Das Führungselement 3 ist in diesem Ausführungsbeispiel aus dem polymeren Werkstoff Polypropylen hergestellt, wobei R1-R3 in der allgemeinen Formel der Komponente (K) Methylgruppen (CH3) aufweist und ein Molekulargewicht von etwa 100.000 g / mol aufweist.The locking arrangement 1 for the opening 2 of a cabinet is designed so that the material of the guide element 3 has about 5% by weight, based on the total weight of the material, of a component (K) that has the general formula R 1 R 2 R 3 Si [O-Si R 4 R 5 ] n -O-SiR 6 R 7 R 8 , where R 1 -R 3 are selected differently from one another and are selected from the group consisting of hydrogen atoms and C 1 -C 10 -alkyl groups , where n has a value greater than 1000.
In this exemplary embodiment, the guide element 3 is made from the polymeric material polypropylene, where R 1 -R 3 in the general formula of component (K) has methyl groups (CH 3 ) and has a molecular weight of about 100,000 g / mol.

Es hat sich als äußerst vorteilhaft herausgestellt, dass der Werkstoff des Führungselementes 3 etwa 5 Gew.-% der Komponente (K) aufweist, da bei bestimmungsgemäßen Gebrauch des Schrankmöbels und dem Öffnen bzw. Schließen des Verschlusselements 4 der Werkstoff des Führungselements 3 nach etwa 80.000 Reibungsbewegungen immer noch einen Gleitreibungskoeffizienten µ gemäß DIN EN ISO 8295 von 0,06 bei glatten Oberflächen aufweist, während im bekannten Stand der Technik derartige Führungselemente wesentlich höhere Gleitreibungskoeffizienten aufweisen bzw. einen erhöhten abrasiven Materialverschleiß aufweisen.It has been found to be extremely advantageous that the material of the guide element 3 comprises about 5% by weight of the component (K), since when the cabinet is used as intended and the closure element 4 is opened or closed, the material of the guide element 3 after about 80,000 Frictional movements still have a coefficient of sliding friction μ according to DIN EN ISO 8295 of 0.06 with smooth surfaces, while in the known prior art such guide elements have significantly higher coefficients of sliding friction or have increased abrasive material wear.

Es liegt jedoch auch im Rahmen der Erfindung, dass der Werkstoff des Profilelements 42 des Verschlusselements 4 etwa 10 Gew.-%, bezogen auf das Gesamtgewicht des Werkstoffes, eine Komponente (K) aufweist, die der allgemeinen Formel R1R2R3Si-[O-Si R4R5]n-O-SiR6R7R8 entspricht, wobei R1-R8 gleich oder verschieden voneinander gewählt sind und ausgewählt sind aus der Gruppe bestehend aus Wasserstoffatomen und C1-C10-Alkylgruppen.However, it is also within the scope of the invention that the material of the profile element 42 of the closure element 4 has about 10% by weight, based on the total weight of the material, of a component (K) that has the general formula R 1 R 2 R 3 Si - [O-Si R 4 R 5 ] n -O-SiR 6 R 7 R 8 , where R 1 -R 8 are selected to be identical or different from one another and are selected from the group consisting of hydrogen atoms and C 1 -C 10 - Alkyl groups.

Durch die erfindungsgemäße Verschlussanordnung 1, welche sich wirtschaftlich und kostengünstig herstellen lässt, ist somit eine geräuscharme, schnelle und schonende Schließbewegung der Verschlusselemente 4 von Schrankmöbeln, Kühlgeräten, Gebäuden und dergleichen möglich, wobei diese ohne zusätzliche Wartungsmaßnahmen eine lange Lebensdauer aufweisen.The closure arrangement 1 according to the invention, which can be produced economically and inexpensively, thus enables a quiet, fast and gentle closing movement of the closure elements 4 of cabinet furniture, refrigerators, buildings and the like, which have a long service life without additional maintenance measures.

Die erfindungsgemäße Verschlussanordnung 1 zeichnet sich weiterhin dadurch aus, dass sie eine wesentlich höhere Verschleißfestigkeit aufweist und das nahezu keine Veränderung des Gleitreibungskoeffizienten µ gemäß DIN EN ISO 8295 bei einer Dauerbelastung beispielsweise nach etwa 80.000 Reibungsbewegungen nachweisbar ist.The closure arrangement 1 according to the invention is further characterized in that it has a much higher wear resistance and that almost no change in the coefficient of sliding friction μ according to DIN EN ISO 8295 can be detected under continuous load, for example after about 80,000 frictional movements.

Ein weiterer Vorteil der erfindungsgemäßen Verschlussanordnung 1 besteht darin, dass bei bestimmungsgemäßen Gebrauch insbesondere bei Kühlgeräten durch die Anwendung von Reinigungsmitteln bzw. Chemikalien keine Beeinträchtigung des Gleitreibungskoeffizienten µ gemäß DIN EN ISO 8295 erfolgt und das die Verschlusselemente 4 auch nach mehrmonatiger Dauerbelastung immer noch mit sehr geringen Verschiebekräften bedienbar sind.Another advantage of the closure arrangement 1 according to the invention is that, when used as intended, especially in refrigerators, the use of cleaning agents or chemicals does not impair the coefficient of sliding friction μ according to DIN EN ISO 8295 and that the closure elements 4 are still very low even after several months of continuous load Displacement forces are operable.
