Definitions

  • the present invention relates to a fitting for braking relative movements between device parts, in particular movements of sliding doors or other doors or furniture parts.
  • furniture parts such as flaps, drawers or doors, in particular cabinet doors and furniture-independent doors, such as room partitioning systems come into consideration.

  • the invention is based on the technical problem of providing a simple and practical fitting for braking moving parts of the device.
  • the invention is directed to a fitting for braking a movement between two relatively moving parts of the device with two complementary fitting parts, which are designed to build during a relative movement of the device parts in an end position a braking friction between each other by conditioning respective surfaces together the friction is a rubber-elastic body of one of the fitting parts involved, and during the braking, a friction-enhancing movement takes place along an inclined to the direction of the braked movement surface of the fitting, wherein a member which carries one of the surfaces to be brought into abutment between two stops with respect to the fitting part, to which the element belongs, is longitudinally displaceable and designed to be taken during braking by the counter-surface associated with the system and when releasing the fitting parts from each other from this counter-surface e to be withdrawn.
  • the inclined surface is a guide surface for the slow-moving element, so that the longitudinally displaceable element by the longitudinal displacement can be moved to the counter-surface or pressed to this stronger, and on a correspondingly designed sliding door system and on the use of the fitting for sliding doors.
  • the friction between surfaces is used, which are brought into abutment for this purpose. At least one of the surfaces belongs to a rubber-elastic body.
  • a movement takes place along an inclined surface of the fitting. This movement along the inclined surface intensifies the friction, thus bringing the rubbing surfaces closer together or pressing them together with greater force.
  • the kinetic energy is dissipated and, at the end of the movement, a frictional connection or frictional connection is established relative to each other in the device parts. This adhesion and at least part of the braking friction must be overcome again when the fitting parts are detached from each other and the device parts are moved relative to each other.
  • the fitting according to the invention is much easier to implement than the initially described prior art.
  • the comparatively more expensive pneumatic damper is replaced by a simple surface friction. This is enhanced by or during the bracing process, as the movement proceeds along the sloping surface.
  • the rubber-elastic body has proven particularly useful in this context because the elastic deformation during braking allows a particularly good conformance of the abrading surfaces, and many suitable rubber-elastic materials provide relatively "matte" surfaces, that is, surfaces that are good for a relative high sliding friction of another surface are suitable.
  • Another inclined surface may be provided on one of the two rubbing surfaces itself; in other words, this surface is then slightly tilted with respect to the direction of movement of the relative movement of the device parts.
  • the exemplary embodiment clearly shows that as a result of this inclined position, as the movement to be braked progresses, a system is first produced and then the contact pressure of the two surfaces is increased.
  • this further inclined surface may be attached to the rubber-elastic body, as the embodiment also shows. But it could also be the counter surface to a surface of the rubber-elastic body.
  • embodiments having rubbing surfaces which are both surfaces of rubber-elastic bodies are also not excluded.
  • the invention additionally provides a longitudinal displaceability of an element of a fitting which carries a surface to be abutted.
  • the oblique surface according to the invention is a guide surface for this longitudinally displaceable element.
  • longitudinal displacement is of course meant a displaceability with respect to the respective remaining fitting part and not the basically given mobility of the two device parts to each other.
  • the longitudinal displacement is limited between two stops. At the beginning or in the course of the braking process, the longitudinally displaceable element is taken along by the respective other surface, that is to say the mating surface, but preferably not retracted from one another until it stops and when the fitting parts are released.
  • the guide along the inclined surface may be connected to another inclined surface on the guided element, specifically the surface designed for friction.
  • two movements take place in this sense along an inclined surface, on the one hand, the longitudinally displaceable element along its guide, on the other hand, the corresponding mating surface along the designed for the system surface of the rubber-elastic body or longitudinally guided element.
  • the inclined guide surface is combined with rubbing surfaces which themselves are not inclined. Then, however, the pressure between the rubbing surfaces can be increased or reduced in the opposite movement by the inclined guide surface.
  • one of the two rubbing surfaces is a surface of a rubber-elastic body, preferably on the guided longitudinally displaceable element.
  • the details already explained can be realized particularly favorably in a design of the fitting parts with on the one hand a hollow seat and on the other hand an engagement projection.
  • the engagement projection is designed for insertion into the hollow receptacle, wherein it carries one of the two surfaces to be brought into contact and the other of the surfaces is arranged in the hollow receptacle.
  • an element in particular the rubber-elastic body, be guided longitudinally displaceable on an inclined surface.
  • the engagement projection is narrow in at least one dimension, and more preferably in two dimensions, ie, a plate or pin ("narrow" in relation to the length of engagement with the cup).
  • a pin may also have a tapered end to facilitate insertion into the hollow seat and preferably has a substantially parallel longitudinal section profile thereafter, ie, a constant thickness.
  • a further improvement of the invention may consist in a cavity adjacent to the rubber-elastic body, on a side opposite to the plant.
  • the rubber-elastic body in the cavity dodge something when he gets through the system under pressure, and react in this form particularly soft and yielding. This is especially true locally.
  • this cavity is arranged centrally with respect to the extension of the rubber-elastic body along the direction of movement and the rubber-elastic body thus effectively softer in the middle than at its edges.
  • this can be realized by the support of the rubber-elastic body on a U-profile shape (with respect to a section along the direction of movement). Two relatively short legs of the U enclose the cavity between them.
  • the rubber-elastic body can then be a simple flat cuboid.
  • the U-profile holder in turn can be guided longitudinally displaceable, in particular on the already mentioned oblique surface.
  • the already frequently used term "oblique” is preferably to be understood as meaning that, in a longitudinal section along the direction of movement and relative to the direction of movement, an angle of at most 20 °, preferably at most 15 ° and more preferably at most 10 ° results. This angle is facing the other fitting part, as the embodiment illustrates.
  • a damping element is also preferred on at least one of the sides of the longitudinally displaceable element.
  • This damping element dampens the stop of the longitudinally displaceable element in the longitudinal movement at the end of the movement distance.
  • It may, for example, be a spring element, in particular a one-piece molded-in spring plastic element.
  • a spring element also acts on the longitudinally displaceable element possibly further away from the stop position to the opposite stop position. For example, it can be ensured with such a spring element that the longitudinally displaceable element is taken along particularly reliably in a "narrow" position, that is to say a position of particularly strong pressure between the rubbing surfaces, when guided along the inclined surface. Conversely, such a spring element can also ensure that the longitudinally displaceable element is taken from such a position when releasing the fitting parts in an "open” position and waits in this position for the next damping process.
  • the longitudinally displaceable element can bear a stop for the other fitting part, namely at a with respect to its insertion rear end of the abutting surface. Stops are of course possible in principle, but such a stop in the longitudinally displaceable element not only has the advantage of reliably catching the other fitting part in a final phase of the movement, if necessary, it also ensures entrainment of the longitudinally displaceable element along the longitudinal displacement path.
  • sliding door systems with a fitting according to the invention or the use thereof for such a sliding door system, in which therefore the door element or door leaf is translationally displaced to close or release the door opening.
  • Sliding door systems are used in furniture construction, in rooms or front doors, in room parts, also for the demarcation of walk-in cabinets, refrigerators or rooms, but also for larger hall doors, garage doors u. ⁇ .
  • the sliding door elements to be moved are heavy.
  • the invention is also directed here to a sliding door system with a fitting according to the above description, which is mounted in particular on the one hand on a rail for holding and on the other hand on the Schleizdoor element, in such a way that the fitting by the rail in the direction perpendicular to the sliding door element is covered.
  • the rail can with its leg cover the side edge itself and cover or, as seen in the horizontal direction, connect substantially to the side edge. Then it covers a space above the side edge, which may be used for mounting element and the like. Use and therefore should be protected from view. Of course, there may be a small slot, so that the term covering only in the sense of a "substantially covering" is to be understood.

  • the rail may include bearings for supporting the sliding door member in the slidable manner in the rail, such as systems having guide rollers and treads therefor. This applies both to the already mentioned case that the holding by the rail corresponds only to a lateral guiding in a web, as well as in the case of a support of a part of or the entire weight of the sliding door element.

Description

Die vorliegende Erfindung bezieht sich auf einen Beschlag zum Bremsen von Relativbewegungen zwischen Vorrichtungsteilen, insbesondere von Bewegungen von Schiebetüren oder auch anderen Türen oder Möbelteilen. In Betracht kommen insbesondere Möbelteile wie Klappen, Schubladen oder Türen, insbesondere Schranktüren und auch von Möbeln unabhängige Türen, so etwa bei Raumteilungssystemen. Auch Kühleinrichtungen, z. B. in großen Lebensmittelgeschäften und Supermärkten, können entsprechende Türsysteme, insbesondere natürlich Schiebetürsysteme, aufweisen.The present invention relates to a fitting for braking relative movements between device parts, in particular movements of sliding doors or other doors or furniture parts. In particular, furniture parts such as flaps, drawers or doors, in particular cabinet doors and furniture-independent doors, such as room partitioning systems come into consideration. Also cooling facilities, z. B. in large grocery stores and supermarkets, corresponding door systems, in particular, of course, sliding door systems have.

Es ist an sich längst bekannt, Bewegungen mechanisch zu dämpfen, beispielsweise die Ein- und/oder Auszugsbewegungen einer 3Möbelschublade oder einer Schiebetür. Damit soll verhindert werden, dass eine Schublade oder Schiebetür wegen etwas zu heftiger Betätigung übermäßig schnell geöffnet oder geschlossen wird und mit Lärm und Erschütterungen verbunden an einen jeweiligen Endanschlag stößt. Solche Fehlbetätigungen können durch mangelnde Achtsamkeit, aber auch durch falsche intuitive Annahmen über den Beladungszustand der Schublade oder die Masse der Tür und damit zu große Kräfte bei der Betätigung entstehen.It has long been known to dampen movements mechanically, for example, the input and / or pull-out movements of a 3-drawer or a sliding door. This is to prevent a drawer or sliding door from being opened or closed excessively quickly because of a too violent operation, and to interfere with a respective end stop with noise and shocks. Such misuse can be caused by lack of awareness, but also by false intuitive assumptions about the loading state of the drawer or the mass of the door and thus too large forces in the operation.

Auch kann es erwünscht sein, eine große Schiebetür oder schwer beladene Schublade, die wegen der Masseträgheit mit einer gewissen Kraft beschleunigt werden muss, um eine Schließ- oder Öffnungsbewegung zu beginnen, nicht ungedämpft bzw. ungebremst in die entgegengesetzte Position fahren zu lassen. Gerade bei schweren Schiebetüren sind zur Beschleunigung der Tür größere Kräfte erforderlich, wobei es für den Benutzer unkomfortabel ist, die Tür vor dem Endanschlag manuell abfangen zu müssen.Also, it may be desirable to have a large sliding door or heavily loaded drawer, which must be accelerated due to inertia with a certain force to begin a closing or opening movement, not to be driven unattenuated or in the opposite position. Especially with heavy sliding doors greater forces are required to accelerate the door, whereby it is uncomfortable for the user to have to catch the door manually before the end stop.

Analoge Überlegungen gelten für viele andere Anwendungsfälle, beispielsweise das Öffnen und Schließen von anderen beweglichen Möbelteilen wie Türen oder Klappen, für Fensterflügel oder Zimmer und Haustüren im Luftzug sowie für Rollläden, insbesondere für Möbel usw. Diese Bereiche sind denkbare und bevorzugte, jedoch nicht ausschließliche Anwendungsbereiche der im Folgenden erläuterten Erfindung.Analogous considerations apply to many other applications, such as the opening and closing of other movable furniture parts such as doors or flaps, for casement or room and front doors in the draft and for shutters, in particular for furniture, etc. These ranges are conceivable and preferred, but not exclusive, fields of application of the invention explained below.

Beispiele für einen bekannten Aufbau einer solchen Dämpfungseinrichtung finden sich in der WO 20061056606 . Diese bekannte und andere Dämpfungseinrichtungen verwenden einen pneumatischen Dämpfer, um ein Vorrichtungstell, beispielsweise eine Schiebetür, im Endbereich ihrer Bewegung zu bremsen. Umgekehrt muss sich die Schiebetür von dem Mechanismus lösen können. Hierzu sind Im Stand der Technik verschiedene Übergabemechanismen bekannt.Examples of a known structure of such a damping device can be found in the WO 20061056606 , These known and other damping devices use a pneumatic damper to brake a device actuator, such as a sliding door, in the end region of its movement. Conversely, the sliding door must be able to detach from the mechanism. For this purpose, various transfer mechanisms are known in the prior art.

Zum Stand der Technik wird ferner verwiesen auf die FR 2 809 760 A1 mit einem Reibungs-Bremsbeschlag für eine Schiebetür, auf die DE 10 2007 041 637 A1 mit einer ebenfalls durch Reibung funktionierenden Bremse für eine Schiebetür und, schließlich auf die dem Oberbegriff des Anspruchs 1 zugrundeliegende EP 1 927 492 A2 mit einem Beschlag für die Schiebetür der Fahrerkabine eines großen Baugeräts.The prior art is further referred to the FR 2 809 760 A1 with a friction brake fitting for a sliding door, on the DE 10 2007 041 637 A1 with a likewise functioning by friction brake for a sliding door and, finally, on which the preamble of claim 1 underlying EP 1 927 492 A2 with a fitting for the sliding door of the cab of a large construction equipment.

Der Erfindung liegt das technische Problem zugrunde, einen einfachen und praktischen Beschlag zum Bremsen bewegter Vorrichtungsteile anzugeben.The invention is based on the technical problem of providing a simple and practical fitting for braking moving parts of the device.

Die Erfindung richtet sich auf einen Beschlag zum Bremsen einer Bewegung zwischen zwei relativ zueinander bewegten Vorrichtungsteilen mit zwei komplementär ausgebildeten Beschlagteilen, die dazu ausgelegt sind, bei einer Relativbewegung der Vorrichtungsteile in eine Endlage eine bremsende Reibung zwischen einander durch Anlage jeweiliger Oberflächen aneinander aufzubauen, wobei an der Reibung ein gummielastischer Körper eines der Beschlagteile beteiligt ist, und während des Bremsens eine die Reibung verstärkende Bewegung entlang einer zu der Richtung der gebremsten Bewegung schrägen Fläche des Beschlags erfolgt, wobei ein Element, das eine der in Anlage zueinander zu bringenden Oberflächen trägt, zwischen zwei Anschlägen bezüglich dem Beschlagteil, zu dem das Element gehört, längs verschieblich ist und dazu ausgelegt ist, beim Bremsen von der für die Anlage zugeordneten Gegen-Oberfläche mitgenommen und beim Lösen der Beschlagteile voneinander von dieser Gegen-Oberfläche zurückgezogen zu werden. Erfindungsgemäß ist die schräge Fläche eine Führungsfläche für das langsverschiebliche Element, sodass das längs verschiebliche Element durch die Längsverschiebung auf die Gegen-Oberfläche zu bewegt beziehungsweise stärker an diese angedrückt werden kann, sowie
auf ein entsprechend ausgestaltetes Schiebetürsystem sowie auf die Verwendung des Beschlags für Schiebetüren.
The invention is directed to a fitting for braking a movement between two relatively moving parts of the device with two complementary fitting parts, which are designed to build during a relative movement of the device parts in an end position a braking friction between each other by conditioning respective surfaces together the friction is a rubber-elastic body of one of the fitting parts involved, and during the braking, a friction-enhancing movement takes place along an inclined to the direction of the braked movement surface of the fitting, wherein a member which carries one of the surfaces to be brought into abutment between two stops with respect to the fitting part, to which the element belongs, is longitudinally displaceable and designed to be taken during braking by the counter-surface associated with the system and when releasing the fitting parts from each other from this counter-surface e to be withdrawn. According to the invention, the inclined surface is a guide surface for the slow-moving element, so that the longitudinally displaceable element by the longitudinal displacement can be moved to the counter-surface or pressed to this stronger, and
on a correspondingly designed sliding door system and on the use of the fitting for sliding doors.

Zum Bremsen der Relativbewegungen von Vorrichtungsteilen wird die Reibung zwischen Oberflächen verwendet, die zu diesem Zweck in Anlage aneinander gebracht werden. Zumindest eine der Oberflächen gehört zu einem gummielastischen Körper. Zudem erfolgt während der gebremsten (Rest-)Bewegung eine Bewegung entlang einer schrägen Fläche des Beschlags. Diese Bewegung entlang der schrägen Fläche verstärkt die Reibung, führt also die reibenden Oberflächen näher aneinander bzw. drückt sie mit größerer Kraft aufeinander. Durch die Reibung wird die Bewegungsenergie dissipiert und entsteht am Ende der Bewegung ein die Vorrichtungsteile relativ zueinander festlegender Reibschluss oder Kraftschluss. Dieser Kraftschluss und zumindest ein Teil der bremsenden Reibung müssen wieder überwunden werden, wenn die Beschlagteile voneinander gelöst und die Vorrichtungsteile relativ zueinander bewegt werden.To brake the relative movements of device parts, the friction between surfaces is used, which are brought into abutment for this purpose. At least one of the surfaces belongs to a rubber-elastic body. In addition, during the braked (rest) movement, a movement takes place along an inclined surface of the fitting. This movement along the inclined surface intensifies the friction, thus bringing the rubbing surfaces closer together or pressing them together with greater force. As a result of the friction, the kinetic energy is dissipated and, at the end of the movement, a frictional connection or frictional connection is established relative to each other in the device parts. This adhesion and at least part of the braking friction must be overcome again when the fitting parts are detached from each other and the device parts are moved relative to each other.

Mit diesem Konzept ist der erfindungsgemäße Beschlag sehr viel einfacher zu realisieren als der eingangs geschilderte Stand der Technik. Insbesondere wird der vergleichsweise aufwendigere pneumatische Dämpfer durch eine einfache Oberflächenreibung ersetzt. Diese wird durch den oder während des Brernsvorgangs verstärkt, Indem die Bewegung entlang der schrägen Fläche erfolgt. Durch das Aufheben der Anlage ist in besonders einfacher Weise eine Freigabe der beiden Vorrichtungstelle voneinander möglich (womit aber weitere Kupplungen nicht ausgeschlossen sind).With this concept, the fitting according to the invention is much easier to implement than the initially described prior art. In particular, the comparatively more expensive pneumatic damper is replaced by a simple surface friction. This is enhanced by or during the bracing process, as the movement proceeds along the sloping surface. By removing the system a release of the two device site is possible from each other in a particularly simple manner (which, however, further clutches are not excluded).

Der gummielastische Körper hat sich in diesem Zusammenhang besonders bewährt, weil die elastische Verformung während des Bremsvorgangs eine besonders gute Formanpassung der aneinander reibenden Oberflächen ermöglicht, und viele geeignete gummielastische Werkstoffe relativ "matte" Oberflächen zur Verfügung stellen, also Oberflächen, die gut für eine relativ hohe Gleitreibung einer anderen Oberfläche darauf geeignet sind.The rubber-elastic body has proven particularly useful in this context because the elastic deformation during braking allows a particularly good conformance of the abrading surfaces, and many suitable rubber-elastic materials provide relatively "matte" surfaces, that is, surfaces that are good for a relative high sliding friction of another surface are suitable.

Eine weitere schräge Fläche kann an einer der beiden reibenden Oberflächen selbst vorgesehen sein; in anderen Worten ist diese Oberfläche dann in Bezug zu der Bewegungsrichtung der Relativbewegung der Vorrichtungsteile etwas gekippt. Das Ausführungsbeispiel zeigt anschaulich, dass durch diese Schräglage bei fortschreitender zu bremsender Bewegung zunächst eine Anlage hergestellt wird und dann der Andruck der beiden Oberflächen aufeinander vergrößert wird.Another inclined surface may be provided on one of the two rubbing surfaces itself; in other words, this surface is then slightly tilted with respect to the direction of movement of the relative movement of the device parts. The exemplary embodiment clearly shows that as a result of this inclined position, as the movement to be braked progresses, a system is first produced and then the contact pressure of the two surfaces is increased.

Dabei kann diese weitere schräge Oberfläche an dem gummielastischen Körper angebracht sein, wie das Ausführungsbeispiel ebenfalls zeigt. Es könnte sich aber auch um die Gegenfläche zu einer Oberfläche des gummielastischen Körpers handeln. Im Übrigen sind Ausführungsformen mit reibenden Oberflächen, die beide Oberflächen gummielastischer Körper sind, ebenfalls nicht ausgeschlossen.In this case, this further inclined surface may be attached to the rubber-elastic body, as the embodiment also shows. But it could also be the counter surface to a surface of the rubber-elastic body. Incidentally, embodiments having rubbing surfaces which are both surfaces of rubber-elastic bodies are also not excluded.

Die Erfindung sieht zusätzlich eine Längsverschieblichkeit eines Elements eines Beschlagteils vor, das eine in Anlage zu bringende Oberfläche trägt. Die erfindungsgemäße schräge Fläche ist eine Führungsfläche für dieses Längsverschiebliche Element. Mit Längsverschieblichkeit ist dabei natürlich eine Verschieblichkeit bezüglich dem jeweiligen restlichen Beschlagteil gemeint und nicht die grundsätzlich gegebene Beweglichkeit der beiden Vorrichtungsteile zueinander. Die Längsverschieblichkeit ist begrenzt zwischen zwei Anschlägen. Zu Anfang oder im Laufe des Bremsvorgangs wird das längsverschiebliche Element von der jeweils anderen Oberfläche, also der Gegenfläche, mitgenommen, vorzugsweise aber nicht zwingend bis zum Anschlag und beim Lösen der Beschlagteile voneinander wieder zurückgezogen. Durch diese Längsverschieblichkeit wird ohne oder bei geringerer Oberflächenreibung ein Wegstück zurückgelegt und dabei die reibungsverstärkende Wirkung der bereits erwähnten Bewegung entlang der schrägen Führungsfläche hervorgerufen. Die Längsverschieblichkeit soll also die Wirkung der schrägen Fläche zur Geltung bringen. Zur Veranschaulichung wird wieder auf das Ausführungsbeispiel verwiesen. Dabei wird durch die Längsverschiebung die Bewegung entlang der schrägen Fläche erzeugt und das entsprechende Element auf die Gegenfläche zu bewegt bzw. an diese stärker angedrückt.The invention additionally provides a longitudinal displaceability of an element of a fitting which carries a surface to be abutted. The oblique surface according to the invention is a guide surface for this longitudinally displaceable element. With longitudinal displacement is of course meant a displaceability with respect to the respective remaining fitting part and not the basically given mobility of the two device parts to each other. The longitudinal displacement is limited between two stops. At the beginning or in the course of the braking process, the longitudinally displaceable element is taken along by the respective other surface, that is to say the mating surface, but preferably not retracted from one another until it stops and when the fitting parts are released. As a result of this longitudinal displaceability, a path is traveled without or with less surface friction, and the friction-enhancing effect of the already mentioned movement along the oblique guide surface is thereby produced. The longitudinal displacement is thus intended to bring out the effect of the oblique surface. For the sake of illustration, reference is again made to the exemplary embodiment. In this case, the movement along the oblique surface is generated by the longitudinal displacement and moves the corresponding element to the counter surface or pressed against this stronger.

Hierbei ist anzumerken, dass die Führung entlang der schrägen Fläche, wie ein Ausführungsbeispiel zeigt, mit einer weiteren schrägen Fläche an dem geführten Element verbunden sein kann, nämlich konkret der für die Reibung ausgelegten Oberfläche. Bei diesem Ausführungsbeispiel finden in diesem Sinn zwei Bewegungen entlang einer schrägen Fläche statt, zum einen die des längsverschieblichen Elements entlang seiner Führung, zum anderen die der entsprechenden Gegenfläche entlang der für die Anlage ausgelegten Oberfläche des gummielastischen Körpers bzw. längsverschieblich geführten Elements. Bei einem anderen Ausführungsbeispiel hingegen ist die schräge Führungsfläche kombiniert mit reibenden Oberflächen, die selbst nicht schräg verlaufen. Dann kann durch die schräge Führungsfläche dennoch der Andruck zwischen den reibenden Oberflächen verstärkt bzw. bei der entgegengesetzten Bewegung vermindert werden. Natürlich ist auch bei dieser Ausgestaltung eine der beiden reibenden Oberflächen eine Oberfläche eines gummielastischen Körpers, und zwar vorzugsweise an dem geführten längsverschieblichen Element.It should be noted that the guide along the inclined surface, as one embodiment shows, may be connected to another inclined surface on the guided element, specifically the surface designed for friction. In this embodiment, two movements take place in this sense along an inclined surface, on the one hand, the longitudinally displaceable element along its guide, on the other hand, the corresponding mating surface along the designed for the system surface of the rubber-elastic body or longitudinally guided element. In contrast, in another embodiment, the inclined guide surface is combined with rubbing surfaces which themselves are not inclined. Then, however, the pressure between the rubbing surfaces can be increased or reduced in the opposite movement by the inclined guide surface. Of course, also in this embodiment, one of the two rubbing surfaces is a surface of a rubber-elastic body, preferably on the guided longitudinally displaceable element.

Die bereits erläuterten Einzelheiten können besonders günstig realisiert werden in einer Ausbildung der Beschlagteile mit einerseits einer Hohlaufnahme und andererseits einem Eingriffsvorsprung. Der Eingriffsvorsprung ist zum Einführen in die Hohlaufnahme ausgelegt, wobei er eine der beiden in Anlage zu bringenden Oberflächen trägt und die andere der Oberflächen in der Hohlaufnahme angeordnet ist. Beispielsweise kann, wie beim Ausführungsbeispiel, in der Hohlaufnahme ein Element, insbesondere der gummielastische Körper, an einer schrägen Fläche längsverschieblich geführt sein.The details already explained can be realized particularly favorably in a design of the fitting parts with on the one hand a hollow seat and on the other hand an engagement projection. The engagement projection is designed for insertion into the hollow receptacle, wherein it carries one of the two surfaces to be brought into contact and the other of the surfaces is arranged in the hollow receptacle. For example, as in the embodiment, in the hollow receiving an element, in particular the rubber-elastic body, be guided longitudinally displaceable on an inclined surface.

Vorzugsweise ist der Eingriffsvorsprung in zumindest einer Dimension und besonders bevorzugter Weise in zwei Dimensionen schmal, also eine Platte oder ein Stift (wobei sich "schmal" im Verhältnis zur Länge des Eingriffs in die Hohlaufnahme versteht). Ein Stift kann zudem ein verjüngtes Ende zur Erleichterung des Einführens in die Hohlaufnahme aufweisen und hat vorzugsweise daran anschließend ein im Wesentlichen paralleles Längsschnittprofil, also eine konstante Stärke.Preferably, the engagement projection is narrow in at least one dimension, and more preferably in two dimensions, ie, a plate or pin ("narrow" in relation to the length of engagement with the cup). A pin may also have a tapered end to facilitate insertion into the hollow seat and preferably has a substantially parallel longitudinal section profile thereafter, ie, a constant thickness.

Eine weitere Verbesserung der Erfindung kann in einem Hohlraum bestehen, der an den gummielastischen Körper angrenzt, und zwar auf einer zu der Anlage entgegengesetzten Seite. Damit kann der gummielastische Körper in den Hohlraum etwas ausweichen, wenn er durch die Anlage unter Druck gerät, und in dieser Form besonders weich und nachgiebig reagieren. Das gilt insbesondere auch lokal. So ist beim Ausführungsbeispiel dieser Hohlraum in Bezug auf die Erstreckung des gummielastischen Körpers längs der Bewegungsrichtung mittig angeordnet und der gummielastische Körper damit in der Mitte effektiv weicher als an seinen Rändern.A further improvement of the invention may consist in a cavity adjacent to the rubber-elastic body, on a side opposite to the plant. Thus, the rubber-elastic body in the cavity dodge something when he gets through the system under pressure, and react in this form particularly soft and yielding. This is especially true locally. Thus, in the embodiment of this cavity is arranged centrally with respect to the extension of the rubber-elastic body along the direction of movement and the rubber-elastic body thus effectively softer in the middle than at its edges.

Beispielsweise lässt sich das realisieren durch die Halterung des gummielastischen Körpers auf einer U-Profilform (in Bezug auf einen Schnitt längs der Bewegungsrichtung). Zwei relativ kurze Schenkel des U schließen dabei den Hohlraum zwischen sich ein. Der gummielastische Körper kann dann ein einfacher flacher Quader sein. Die U-Profilhalterung wiederum kann längsverschieblich geführt sein, insbesondere an der bereits erwähnten schrägen Fläche.For example, this can be realized by the support of the rubber-elastic body on a U-profile shape (with respect to a section along the direction of movement). Two relatively short legs of the U enclose the cavity between them. The rubber-elastic body can then be a simple flat cuboid. The U-profile holder in turn can be guided longitudinally displaceable, in particular on the already mentioned oblique surface.

Der bereits häufig benutzte Begriff "schräg" ist im Rahmen dieser Erfindung vorzugsweise so zu verstehen, dass sich im Längsschnitt entlang, der Bewegungsrichtung und relativ zur Bewegungsrichtung ein Winkel von höchstens 20°, vorzugsweise höchstens 15° und besonders bevorzugter Weise höchstens 10° ergibt. Dieser Winkel ist dabei dem anderen Beschlagteil zugewandt, wie das Ausführungsbeispiel veranschaulicht.In the context of this invention, the already frequently used term "oblique" is preferably to be understood as meaning that, in a longitudinal section along the direction of movement and relative to the direction of movement, an angle of at most 20 °, preferably at most 15 ° and more preferably at most 10 ° results. This angle is facing the other fitting part, as the embodiment illustrates.

In Verbindung mit dem bereits beschriebenen längsverschieblichen Element ist ferner ein Dämpfungselement auf zumindest einer der Seiten des längsverschieblichen Elements bevorzugt. Dieses Dämpfungselement dämpft den Anschlag des längsverschieblichen Elements bei der Längsbewegung am Ende der Bewegungsstrecke ab. Es kann sich zum Beispiel um ein Federelement, insbesondere ein einstückig angeformtes fedemdes Kunststoffelement, handeln. Ein Federelement beaufschlagt das längsverschiebliche Element ferner möglicherweise von der Anschlagsposition weg bis zur entgegengesetzten Anschlagsposition. So kann mit einem solchen Federelement zum Beispiel dafür gesorgt werden, dass das längsverschiebliche Element bei einer Führung entlang der schrägen Fläche besonders zuverlässig In eine "enge" Position, also eine Position eines besonders starken Andrucks zwischen den reibenden Oberflächen, mitgenommen wird. Umgekehrt kann ein solches Federelement auch sicherstellen, dass das längsverschiebliche Element aus einer solchen Position beim Lösen der Beschlagsteile in eine "offene" Position mitgenommen wird und in dieser Position auf den nächsten Dämpfungsvorgang wartet.In connection with the longitudinally displaceable element already described, a damping element is also preferred on at least one of the sides of the longitudinally displaceable element. This damping element dampens the stop of the longitudinally displaceable element in the longitudinal movement at the end of the movement distance. It may, for example, be a spring element, in particular a one-piece molded-in spring plastic element. A spring element also acts on the longitudinally displaceable element possibly further away from the stop position to the opposite stop position. For example, it can be ensured with such a spring element that the longitudinally displaceable element is taken along particularly reliably in a "narrow" position, that is to say a position of particularly strong pressure between the rubbing surfaces, when guided along the inclined surface. Conversely, such a spring element can also ensure that the longitudinally displaceable element is taken from such a position when releasing the fitting parts in an "open" position and waits in this position for the next damping process.

Ein Beispiel für ein einstückiges Kunststofffederelement ist in einem der Ausführungsbeispiele gezeigt.An example of a one-piece plastic spring element is shown in one of the embodiments.

Ferner kann das längsverschiebliche Element einen Anschlag für das andere Beschlagteil tragen, und zwar an einem in Bezug auf dessen Einführbewegung hinteren Ende der in Anlage zu bringenden Oberfläche. Anschläge sind natürlich grundsätzlich möglich, jedoch hat ein solcher Anschlag bei dem längsverschieblichen Element nicht nur den Vorteil, das andere Beschlagteil sicher in einer Endphase der Bewegung aufzufangen, soweit nötig, es stellt zudem eine Mitnahme des längsverschieblichen Elements entlang der Längsverschiebungsstrecke sicher.Further, the longitudinally displaceable element can bear a stop for the other fitting part, namely at a with respect to its insertion rear end of the abutting surface. Stops are of course possible in principle, but such a stop in the longitudinally displaceable element not only has the advantage of reliably catching the other fitting part in a final phase of the movement, if necessary, it also ensures entrainment of the longitudinally displaceable element along the longitudinal displacement path.

Weitere Aspekte der Erfindung betreffen Schiebetürsysteme mit einem erfindungsgemäßen Beschlag bzw. die Verwendung desselben für ein solches Schiebetürsystem, bei dem also das Türelement oder Türblatt translatorisch verschoben wird, um die Türöffnung zu verschließen oder freizugeben. Schiebetürsysteme finden Anwendung im Möbelbau, bei Zimmer oder Haustüren, bei Raumteilem, auch zur Abgrenzung von begehbaren Schränken, Kühlgeräten oder -räumen, aber auch bei größeren Hallentoren, Garagentoren u.Ä. Je nach Anwendung sind die zu bewegenden Schiebetürelemente schwer.Further aspects of the invention relate to sliding door systems with a fitting according to the invention or the use thereof for such a sliding door system, in which therefore the door element or door leaf is translationally displaced to close or release the door opening. Sliding door systems are used in furniture construction, in rooms or front doors, in room parts, also for the demarcation of walk-in cabinets, refrigerators or rooms, but also for larger hall doors, garage doors u.Ä. Depending on the application, the sliding door elements to be moved are heavy.

Die Erfindung richtet sich hier auch auf ein Schiebetürsystem mit einem Beschlag nach der vorstehenden Beschreibung, der insbesondere einerseits an einer Schiene zum Halten und andererseits an dem Schlebetürelement angebracht ist, und zwar so, dass der Beschlag durch die Schiene in der auf dem Schiebetürelement senkrechten Blickrichtung abgedeckt ist.The invention is also directed here to a sliding door system with a fitting according to the above description, which is mounted in particular on the one hand on a rail for holding and on the other hand on the Schleizdoor element, in such a way that the fitting by the rail in the direction perpendicular to the sliding door element is covered.

Die Grundidee besteht darin, dass bei den allermeisten gängigen Schiebetürsystemen ohnehin Schienen vorgesehen sind, die das Schiebetürelement nicht nur halten, sondern auch mit einem Schienenschenkel zumindest einen Raum oberhalb der entsprechenden Seitenkante des Schiebetürelements umfassen und abdecken. Hierbei ist die Blickrichtung auf das Schiebetürelement, also senkrecht in Bezug auf seine flächige Erstreckung, gemeint. "Halten" bedeutet hier nicht notwendigerweise, dass die Schiene das gesamte Gewicht oder überhaupt nur das Gewicht des Schiebetürelements trägt, sondern bezieht sich auch auf solche Fälle, in denen die Schiene beispielsweise nur gegen ungewünschte seitliche Bewegungen, also gewissermaßen in der erwähnten Blickrichtung, vorgesehen ist und insoweit das Schiebetürelement in der Bahn hält.The basic idea is that in the vast majority of sliding door systems anyway rails are provided which not only hold the sliding door element, but also include and cover at least one space above the corresponding side edge of the sliding door element with a rail leg. Here, the viewing direction on the sliding door element, that is perpendicular with respect to its areal extension, meant. "Holding" here does not necessarily mean that the rail carries the entire weight or even only the weight of the sliding door element, but also refers to those cases in which the rail, for example, only against unwanted lateral movements, so to speak in the mentioned direction, provided is and as far as the sliding door element stops in the track.

Die Schiene kann mit ihrem Schenkel die Seitenkante selbst umfassen und abdecken oder auch, in horizontaler Blickrichtung gesehen, im Wesentlichen an die Seitenkante anschließen. Dann deckt sie einen Raum oberhalb der Seitenkante ab, der für Montagelement u.Ä. Verwendung findet und daher vor Blicken geschützt werden soll. Natürlich kann es dabei einen kleinen Schlitz geben, sodass der Begriff des Abdeckens nur im Sinne eines "im Wesentlichen Abdecken" zu verstehen ist.The rail can with its leg cover the side edge itself and cover or, as seen in the horizontal direction, connect substantially to the side edge. Then it covers a space above the side edge, which may be used for mounting element and the like. Use and therefore should be protected from view. Of course, there may be a small slot, so that the term covering only in the sense of a "substantially covering" is to be understood.

Wenn nun diese Schiene auch dazu genutzt wird, den Beschlag abzudecken, Indem dieser innerhalb der Schiene angeordnet wird, so sind die sonst am Markt zu beobachtenden Verschlechterungen des äußeren Erscheinungsbildes durch Dämpferkonstruktionen vermeidbar. Dazu muss die Schiene nicht einmal etwas größere Abmessungen aufweisen als sonst notwendig.Now, if this rail is also used to cover the fitting by placing it within the rail, then those are otherwise observed in the market Deterioration of external appearance by damper designs avoidable. For this, the rail does not even have to have slightly larger dimensions than otherwise necessary.

Bevorzugt ist der Beschlag zwischen der Schiene und dem Schiebetürelement montiert. Dies ist allerdings nicht unbedingt notwendig. Denkt man sich beispielsweise ein umgekehrtes L-Profil, das mit einem Schenkel horizontal an einer Zimmerdecke montiert ist und mit dem anderen vertikalen Schenkel in der beschriebenen Weise zumindest den Raum über der Seitenkante abdeckt, und denkt man sich ferner dieses L-Profil vor einer Wand, also in einer Ecke, montiert, so könnte der Beschlag auch durchaus zwischen dem Schiebetürelement und der Zimmerwand angebracht sein. Erfindungsgemäß bevorzugt sind jedoch Lösungen, die unabhängig von solchen Montagesituationen für eine Sichtabdeckung sorgen und damit den Beschlag zwischen Schiene und Schiebetürelement vorsehen, In Betracht kommen bei der beschriebenen L-Profilforrn damit der Zwischenraum zwischen dem horizontalen Schenkel des "L" und dem Schiebetürelement, also gewissermaßen eine Montage des Beschlags "über" dem Schlebetürelement, und der Zwischenraum zwischen dem vertikalen Schenkel der Schiene und dem Schiebetürelement, also gewissermaßen eine Montage "vor" dem Schiebetürelement. Bevorzugt ist, auch bei anderen Profilformen, eine Montage "über" dem Schiebetürelement, also zwischen einem horizontalen Schenkel der Schiene bzw. ihrer oberen Wand, und dem Schiebetürelement. Bevorzugt sind ferner Schienen in einer umgekehrten U-Form, die also gegenüber der beschriebenen L-Form einen weiteren vertikalen Schenkel aufweisen.Preferably, the fitting between the rail and the sliding door element is mounted. This is not necessary. If, for example, one thinks of an inverted L-profile which is horizontally mounted on a ceiling with one leg and at least covers the space above the side edge with the other vertical leg in the manner described, and one also thinks of this L-profile in front of a wall , so in a corner, mounted, the fitting could well be mounted between the sliding door element and the wall of the room. According to the invention, however, preferred are solutions that provide regardless of such mounting situations for a visual cover and thus provide the fitting between the rail and sliding door element, come into consideration in the described L-Profilforrn thus the gap between the horizontal leg of the "L" and the sliding door element, ie as it were a mounting of the fitting "on" the Schlebetürelement, and the space between the vertical leg of the rail and the sliding door element, so to speak, a mounting "before" the sliding door element. Preferably, even with other profile shapes, a mounting "on" the sliding door element, ie between a horizontal leg of the rail or its upper wall, and the sliding door element. Also preferred are rails in an inverted U-shape, which thus have a further vertical leg relative to the described L-shape.

Die Schiene kann Lager zur Lagerung des Schiebetürelements in der verschiebbaren Weise in der Schiene aufweisen, etwa Systeme mit Führungsrollen und Laufflächen für diese. Dies gilt sowohl für den bereits erwähnten Fall, dass das Halten durch die Schiene lediglich einem seitlichen Führen in einer Bahn entspricht, als auch für den Fall einer Abstützung eines Teils des oder des gesamten Gewichts des Schiebetürelements.The rail may include bearings for supporting the sliding door member in the slidable manner in the rail, such as systems having guide rollers and treads therefor. This applies both to the already mentioned case that the holding by the rail corresponds only to a lateral guiding in a web, as well as in the case of a support of a part of or the entire weight of the sliding door element.

Es ist ferner bevorzugt, dass der Beschlag bei einer oberen Schiene angebracht ist, wenngleich Schiebetürsysteme meistens zusätzlich auch untere Schienen im Bodenbereich aufweisen. Bei den unteren Schienen sind eine minimale Baugröße und daher häufig kein zusätzlicher mechanischer Aufwand gewünscht. Ferner sind sie selbst dann Blicken von oben besonders gut zugänglich, wenn eine Sichtabdeckung in der (horizontalen) Richtung senkrecht zur Schiebetürelementebene besteht.It is further preferred that the fitting is mounted on an upper rail, although sliding door systems usually additionally also have lower rails in the floor area. At the lower rails are a minimum size and therefore often no additional mechanical effort desired. Furthermore, they are particularly well accessible even when viewed from above, when there is a visual coverage in the (horizontal) direction perpendicular to the sliding door element level.

Bevorzugt ist schließlich eine Anwendung im Bereich von Schiebetürsystemen mit besonders schweren Schiebetürelementen, wie sie bei Raumteilem, Abteilungen von begehbaren Schränken, Toren und Zimmer und Haustüren auftreten, also außerhalb der eigentlichen Möbel. Sie richtet sich demnach bevorzug auf Schiebetürsysteme, die an Immer- oder Hauswänden montiert sind.Finally, an application in the field of sliding door systems with particularly heavy sliding door elements, as they occur in room parts, departments of walk-in cabinets, gates and rooms and front doors, ie outside of the actual furniture is preferred. It is accordingly Favor to sliding door systems that are mounted on Immer- or house walls.

Im Folgenden wird die Erfindung anhand von Ausführungsbeispielen näher erläutert, wobei die einzelnen Merkmale in Verbindung mit Anspruch 1 auch in anderen Kombinationen erfindungswesentlich sein können und sich grundsätzlich auf alle Anspruchskategorien beziehen.

Figur 1 zeigt übereinander vier Einzeldarstellungen mit den selben Teilen, aber zu unterschiedlichen aufeinander folgenden Zeitpunkten. Dabei ist vereinfacht in horizontaler Seitenansicht das Einfahren einer Schiebetür 1 in eine in der letzten Einzeldarstellung unten erreichte Endposition dargestellt. Die Einzeldarstellung links oben ist eine ebenfalls schematisierte Ansicht in ebenfalls horizontaler Blickrichtung, aber um 90° verdreht, also in Bewegungsrichtung gesehen. FIG. 1 shows on top of each other four individual representations with the same parts, but at different successive times. In this case, the retraction of a sliding door 1 into a final position reached in the last individual representation is shown simplified in a horizontal side view. The single view on the top left is also a schematized view in a horizontal direction, but rotated by 90 °, ie seen in the direction of movement.

Man erkennt eine hier nur mit ihrem oberen linken Eckbereich dargestellte "hängende" Schiebetür 1, die über einen Zapfen 2 an einem. Laufwagen 3 hängt. Die in Bewegungsrichtung dargestellte Ansicht oben links zeigt, dass der Laufwagen 3 beidseits Räder 4 aufweist, die rechts daneben in der Seitenansicht erkennbar paarweise vorgesehen sind. Mit diesen insgesamt vier Rädern 4 läuft der Wagen 3 in einer in der kleinen Darstellung links oben erkennbaren Laufschiene 5, die zu diesem Zweck ein umgekehrtes U-Profil aufweist, dessen U-Schenkel jeweils nach innen einen leicht gewölbten Fortsatz als Lauffläche für die Räder 4 tragen. In dieser Form lässt sich die Schiebetür 1 entlang der Laufschiene 5 hin und her fahren. Sie kann gleichzeitig an ihrem nicht dargestellten unteren Ende geführt und sogar auch gestützt sein, aber auch am unteren Ende frei hängen.It can be seen here a "hanging" sliding door 1 shown here only with its upper left corner region, which via a pin 2 at a. Carriage 3 hangs. The in the direction of movement shown top left shows that the carriage 3 has on both sides wheels 4, which are provided on the right side in the side view recognizable in pairs. With these four wheels 4 in total, the carriage 3 runs in a small illustration at the top left visible running rail 5, which has for this purpose an inverted U-profile, the U-legs in each case a slightly curved extension as a running surface for the wheels. 4 wear. In this form, the sliding door 1 can be moved back and forth along the running rail 5. It can be performed at the same time at its lower end, not shown, and even supported, but also hang freely at the bottom.

An dem in den Figuren in Fahrtrichtung vorderen (also in den vier übereinander liegenden Einzeldarstellungen linken) Ende des Wagens 3 ist ein Ansatz 6 mit einem stiftartigen Eingriffsvorsprung 7 angebracht, der in Bewegungsrichtung vorsteht und an seinem äußersten Ende mit einer Spitze 8 verjüngt ist. Hierbei kann es sich um ein Kunststoffspritzgussteil handeln. Eine metallische Ausführung ist aber auch geeignet. Der Ansatz 6 kann durch Verschrauben oder andere Verbindungstechniken auch an Wagen bestehender Rollsysteme angebracht werden. Im Übrigen kann der Ansatz 6 insbesondere bei Schiebetürsystemen ohne einen Zapfen 2, bei denen die Schiebetür 1 selbst bis an oder in den sichtverdeckten Bereich reicht, direkt an der Schiebetür 1 angebracht werden.At the front in the figures in the direction of travel (ie in the four superimposed individual representations) end of the carriage 3, a projection 6 is mounted with a pin-like engagement projection 7, which projects in the direction of movement and is tapered at its outermost end with a tip 8. This may be a plastic injection molded part. A metallic version is also suitable. The lug 6 may also be attached to trolleys of existing rolling systems by bolting or other joining techniques. Incidentally, the projection 6 can be attached directly to the sliding door 1, in particular in the case of sliding door systems without a pin 2, in which the sliding door 1 itself extends as far as or into the visible area.

Im Unterschied zu diesem mit dem Wagen 3 und damit mit der Schiebetür 1 mitbewegten Stift 7 ist ebenfalls in der Schiene 5 eine kastenartige Hohlaufnahme 9 angebracht, in der in Bewegungsrichtung gesehenen Ansicht oben links aber nicht eingezeichnet. Die Hohlaufnahme 9 hat an ihrem linken Ende einen Befestigungsabschnitt 10 mit zwei Befestigungslöchern zur Montage an der Schiene 5. Die Befestigungslöcher sind nur symbolisch dargestellt und könnten in diesem Fall in günstiger Weise vertikal verlaufen. Im Übrigen können der Ansatz 6 mit dem Eingriffsvorsprung 7 einerseits und die Hohlaufnahme 9 andererseits auch vertauscht werden.In contrast to this with the carriage 3 and thus mitbewegten with the sliding door 1 pin 7 a box-like hollow receptacle 9 is also mounted in the rail 5, in the direction seen in the direction of movement top left but not shown. The hollow seat 9 has at its left end a mounting portion 10 with two mounting holes for mounting on the rail 5. The mounting holes are shown only symbolically and could run in a favorable manner vertically in this case. Incidentally, the projection 6 with the engagement projection 7 on the one hand and the hollow seat 9 on the other hand can also be reversed.

Im Übrigen weist die Hohlaufnahme 9 einen inneren Hohlraum mit einer gegenüber der horizontalen um ca. 4 - 5°, vorzugsweise max. 10° verkippten schrägen Dachfläche 11 auf, sowie eine an ihrem rechten unteren Bereich angeordnete Einführöffnung 12 zum Einfahren des Stifts 7. An der schrägen Fläche 11 liegt ein U-Profil-Träger 13 an, wobei die U-Schenkel flach und stumpfartig ausgebildet sind. Dieser U-Profil-Träger 13 ist, wie die Figuren übereinander im Vergleich zeigen, entlang der schrägen Fläche 11 längsverschieblich geführt und liegt in den oberen beiden Darstellungen in der Führung rechts außen und in den unteren beiden Darstellungen links außen. Die Führung kann einfach dadurch bewerkstelligt werden, dass der U-Profil-Träger in einer zu der Zeichenebene senkrechten Richtung nach oben und unten etwas über den Hohlraum übersteht und in Schlitze eingreift, von denen der im Sinn der Figur hintere in den Figuren angedeutet ist.In addition, the hollow seat 9 has an inner cavity with respect to the horizontal by about 4-5 °, preferably max. 10 ° inclined oblique roof surface 11, and arranged at its lower right portion insertion opening 12 for retracting the pin. 7 On the inclined surface 11 is a U-profile support 13, wherein the U-legs are flat and formed like a stump. This U-profile support 13 is, as the figures show one above the other in comparison, along the inclined surface 11 guided longitudinally displaceable and lies in the upper two representations in the guide right outside and in the lower two representations left outside. The guide can be accomplished simply by projecting the U-profile support up and down slightly beyond the cavity in a direction perpendicular to the plane of the drawing, and engaging in slots, the rear of which is indicated in the figures.

Der U-Profil-Träger 13 trägt im Übrigen an seiner Unterseite einen gummielastischen Körper 14, der ein flacher Quader mit etwa den selben Grundmaßen wie der U-Profil-Träger 13 abzüglich der Führungsvorsprünge ist. Seine untere Oberfläche ist mit 15 bezeichnet und erhöht den bereits erwähnten Schräglagenwinkel um etwa 1°. Der U-Profil-Träger 13 kann genauso wie der Stift 7 aus einem härteren Kunststoff oder Metall bestehen; der gummielastische Körper 14 besteht vorzugsweise aus einem spritzbaren thermoelastischen Elastomer, einem Naturkautschuk oder synthetischen Kautschukmaterial oder auch aus Silikon.Incidentally, the U-profile carrier 13 carries on its lower side a rubber-elastic body 14, which is a flat cuboid with approximately the same basic dimensions as the U-profile carrier 13 minus the guide projections. Its lower surface is designated 15 and increases the already mentioned skew angle by about 1 °. The U-profile support 13 may be the same as the pin 7 made of a harder plastic or metal; the rubber-elastic body 14 is preferably made of a sprayable thermoelastic elastomer, a natural rubber or synthetic rubber material or silicone.

Die Abfolge der Einzeldarstellungen veranschaulicht die Funktionsweise: Oben ist der Stift 7 einschließlich seiner Spitze 8 noch von der Hohlaufnahme 9 getrennt und bewegt sich mit der Schiebetür 1 darauf zu. In der zweiten Darstellung von oben ist die Spitze 8 bereits in die Einführöffnung 13 eingedrungen und hat zusammen mit dem vordersten Bereich des Abschnitts des Stifts 7 mit parallelem Längsprofil bereits eine Anlage an der unteren inneren Begrenzungsfläche des Hohlraums und vor allem an der unteren Oberfläche 15 des gummielastischen Körpers 14 hergestellt.The sequence of the individual representations illustrates the mode of operation: At the top, the pin 7, including its tip 8, is still separated from the hollow seat 9 and moves with the sliding door 1 toward it. In the second view from above, the tip 8 has already penetrated into the insertion opening 13 and, together with the foremost area of the section of the parallel longitudinal profile pin 7, already abuts against the lower inner boundary surface of the cavity and especially on the lower surface 15 of the cavity made of rubber elastic body 14.

Diese Anlage erzeugt einen gewissen Reibschluss, weswegen sich der gummielastische Körper 14 zusammen mit dem U-Profil-Träger 13 in seiner Längsführung um ein kleines Stück weiter nach links mitbewegt, wie die von oben dritte Figur zeigt. Hierdurch wird der gummielastische Körper 14 etwas abgesenkt, sodass der Reibschluss zwischen dem Stift 7 und seiner unteren Oberfläche verstärkt wird. Das gilt auch für den Reibschluss mit dem Gegenlager, also der unteren inneren Begrenzungsfläche des Hohlraums.This system generates a certain frictional engagement, which is why the rubber-elastic body 14 moves along with the U-profile support 13 in its longitudinal guide a little further to the left, as shown in the third third figure above. As a result, the rubber-elastic body 14 is lowered slightly, so that the frictional engagement between the pin 7 and its lower surface is reinforced. This also applies to the frictional engagement with the counter bearing, ie the lower inner boundary surface of the cavity.

Die Massenträgheit der Schiebetür 1 schiebt den Stift 7 weiter vor, wobei die Reibung die Bewegungsenergie abbaut. Der gummielastische Körper 14 gibt dabei im Volumen, aber vor allem auch nach oben biegend nach und biegt sich etwas in den Hohlraum zwischen den beiden U-Schenkeln des Trägers 13 hoch, wie die unterste Darstellung in Figur 1 zeigt. In diesem Zustand bleibt der Stift mehr oder weniger weit eingedrungen stecken, wobei der in Figur 1 linke U-Schenkel des Trägers 13 ganz am Ende des möglichen Bewegungswegs für den Stift 7 einen relativ großen Reibwiderstand vorsieht. Damit wird einem "Durchschlagen" des Stifts vorgebeugt, wenn die Schiebetür 1 mit sehr viel Schwung heranbewegt wird.The inertia of the sliding door 1 pushes the pin 7 further, wherein the friction dissipates the kinetic energy. The rubber-elastic body 14 is in the volume, but above all bending upwards and bends slightly into the cavity between the two U-legs of the carrier 13 high, as the bottom view in FIG. 1 shows. In this state, the pen remains stuck more or less penetrated, with the in FIG. 1 Left U-leg of the carrier 13 at the very end of the possible path of movement for the pin 7 provides a relatively large frictional resistance. This prevents a "strike through" of the pen, if the sliding door 1 is moved up with a lot of momentum.

Insgesamt kann in dieser Form die Schiebetür 1 wirksam und "weich" abgebremst und in ihrer Endposition fixiert werden. Die Endposition kann durch die Befestigung der Hohlaufnahme 9 innerhalb der Schiene 5 eingestellt oder verändert werden. Eine entsprechende Ausgestaltung ist natürlich auch an einer entgegengesetzten Endposition des Bewegungsweges der Schiebetür 1 möglich, wozu vorzugsweise ein weiterer Wagen 3 am entgegengesetzten oberen Ende der Schiebetür 1 mit einem entsprechenden Beschlag ausgestattet wird.Overall, in this form, the sliding door 1 effectively and "soft" braked and fixed in its final position. The end position can be adjusted or changed by the attachment of the hollow seat 9 within the rail 5. A corresponding configuration is of course also possible at an opposite end position of the movement path of the sliding door 1, for which purpose preferably a further carriage 3 is provided at the opposite upper end of the sliding door 1 with a corresponding fitting.

Figur 2 zeigt eine Bewegung mit umgedrehter Richtung, also ein Lösen der Schiebetür 1 aus ihrer Verankerung gemäß Figur 1 unten. Dabei entsprechen die fünf Einzeldarstellungen in Figur 2 hinsichtlich der Art der Darstellung denen in Figur 1. Insbesondere entspricht die oberste rechte Einzeldarstellung in Figur 2 der untersten in Figur 1 und entspricht die unterste Einzeldarstellung in Figur 2 der obersten rechten in Figur 1; ferner Ist die Ansicht in Blickrichtung längs der Bewegungsrichtung links oben identisch mit der in Figur 1. FIG. 2 shows a movement with the direction reversed, ie a release of the sliding door 1 from its anchorage according to FIG. 1 below. The five individual representations correspond to FIG. 2 in terms of the manner of presentation those in FIG. 1 , In particular, the top right individual representation corresponds to FIG. 2 the lowest in FIG. 1 and corresponds to the lowest individual representation in FIG. 2 the top right in FIG. 1 ; Furthermore, the view in the direction of view along the direction of movement top left is identical to in FIG. 1 ,

Allerdings zeigt die von oben gezählt zweite Einzeldarstellung in Figur 2 abgesehen von der nach rechts gerichteten Bewegung der Schiebetür 1 und des Wagens 3 einen maßgeblichen Unterschied zwischen dem Hineinfahren des Stiftes 7 in die Hohlaufnahme 9 und dem Herausziehen. Man erkennt nämlich, dass das von der obersten Einzeldarstellung in Figur 2 zur zweitobersten Einzeldarstellung erfolgte geringfügige Herausziehen des Stiftes zunächst vor allem den U-Profil-Träger 13 in seiner Längsverschieblichkeit zurückgezogen hat. Die Reibung dieser Längsführung ist nämlich deutlich geringer als die Reibung zwischen dem Stift 7 und den ihn berührenden Flächen in der Hohlaufnahme 9, insbesondere der unteren Oberfläche 15 des gummielastischen Körpers 14. Dieses Zurückfahren des U-Profil-Trägers 13 verringert infolge der schrägen Orientierung seiner Führungsfläche 11 den vertikalen Andruck auf die Reibungsflächen und, im Vergleich der obersten und zweitobersten Darstellung in Figur zu erkennen, die Verbiegung des gummielastischen Körpers 14 in den Hohlraum darüber. Dementsprechend lässt sich der Stift 7 in der Folge, also in dem Schritt von der zweitobersten zur drittobersten Darstellung in Figur 2, leichter aus der Hohlaufnahme 9 herausziehen, um diese dann, wie in Figur 2 gezeigt, ganz zu verlassen.However, the second individual representation counted from above shows in FIG. 2 apart from the rightward movement of the sliding door 1 and the carriage 3 a significant difference between the driving in of the pin 7 in the hollow seat 9 and the withdrawal. One recognizes that this from the highest single representation in FIG. 2 for the second-highest individual presentation was done slightly pulling out of the pin first, especially the U-profile support 13 has retracted in its longitudinal displacement. The friction of this longitudinal guide is namely significantly less than the friction between the pin 7 and the touching him This retraction of the U-shaped support 13 reduces due to the oblique orientation of its guide surface 11, the vertical pressure on the friction surfaces and, in comparison of the top and second top view in FIG to recognize the bending of the rubber elastic body 14 in the cavity above. Accordingly, the pin 7 can be in the sequence, ie in the step from the second-highest to the third uppermost representation in FIG. 2 , easier to pull out of the hollow 9, to this then, as in FIG. 2 shown to leave completely.

Die Längsverschieblichkeit entlang der schrägen Fläche sorgt also beim Hineinfahren und Festklemmen des Stiftes 7 oder allgemeiner ausgedrückt des Eingriffsvorsprungs für eine Erhöhung der Reibung durch vermehrten Andruck und verringert die Reibung beim Herausziehen dementsprechend umgekehrt. Wegen der deutlich höheren Reibung zwischen Eingriffsvorsprung 7 und zugeordneter Gegenfläche, hier der unteren Oberfläche 15 des gummielastischen Körpers 14, im Vergleich zu der Reibung in der Führung der Längsverschieblichkeit des U-Profil-Trägers 13 ergeben sich damit einerseits beim Abbremsen und Festklemmen (hinsichtlich weiterer Bewegung in der Einführrichtung) hohe Reibungskräfte und andererseits vergleichsweise niedrigere Reibungskräfte beim Herausfahren in umgekehrter Richtung.The longitudinal displacement along the inclined surface thus ensures when driving in and clamping the pin 7 or more generally expressed the engagement projection for an increase in friction by increasing pressure and reduces the friction when pulling out accordingly reversed. Because of the significantly higher friction between the engagement projection 7 and associated mating surface, here the lower surface 15 of the rubber elastic body 14, compared to the friction in the leadership of the longitudinal displacement of the U-profile support 13 thus arise on the one hand during braking and clamping (with respect Movement in the insertion direction) high friction forces and on the other hand comparatively lower frictional forces when moving out in the opposite direction.

Schließlich erkennt man, dass eine schräge Orientierung einer Führungsfläche, wie hier der Fläche 11, für ein längsverschiebliches Element, das an dem Reibschluss beteiligt ist, für eine entsprechende Zunahme der Reibung sorgen kann. Wenn man sich in dem gezeichneten Ausführungsbeispiel die untere Oberfläche des gummielastischen Körpers 14 horizontal vorstellt, würde der Eingriffsvorsprung 7 den gummielastischen Körper 14 dennoch mit zunehmendem Eindringen mitnehmen und damit diese horizontale Fläche durch die schräge Führung nach unten gedrückt.Finally, it can be seen that an oblique orientation of a guide surface, as here the surface 11, for a longitudinally displaceable element, which is involved in the frictional engagement, can provide a corresponding increase in the friction. If one imagines horizontally in the illustrated embodiment, the lower surface of the rubber-elastic body 14, the engaging projection 7 would take the rubber-elastic body 14 with increasing penetration and thus pressed this horizontal surface by the oblique guide down.

Man erkennt auch, dass der Hohlraum zwischen den beiden Schenkeln der U-ProfilHalterung 13 für die elastische Verformung des gummielastischen Körpers 14 hilf reich, aber nicht notwendig ist. Er könnte im Übrigen beispielsweise auch dadurch hergestellt werden, dass man auf der Oberseite des gummielastischen Körpers 14 selbst eine Ausnehmung vorsieht, und ist Im Übrigen natürlich nicht zwingend mit der längsverschieblichen Führung verbunden.It can also be seen that the cavity between the two legs of the U-profile holder 13 for the elastic deformation of the rubber-elastic body 14 helpful rich, but not necessary. Incidentally, it could also be produced, for example, by providing a recess on the upper side of the rubber-elastic body 14 itself, and of course, of course, is not necessarily connected to the longitudinally displaceable guide.

Schließlich zeigen die Figuren deutlich, dass sich nicht nur der Wagen 3 mit seinen vier Rädern 4, sondern auch der vollständige Beschlag mit dem Eingriffsvorsprung 7, der Hohlaufnahme 9 und deren Halterung 10 innerhalb der Laufschiene 5 unterbringen und damit sehr wirksam "verstecken" lassen. Dies würde sinngemäß auch für andere Schienenformen gelten.Finally, the figures clearly show that not only the car 3 with its four wheels 4, but also the complete fitting with the engaging projection 7, the hollow seat 9 and its holder 10 accommodate within the track 5 and thus very effectively "hide" leave. This would apply mutatis mutandis to other types of rails.

Es sind verschiedene Möglichkeiten denkbar, die Reibungseigenschaften des Beschlags bei der Herstellung, im Rahmen der Installation oder auch nach Verschleiß anzupassen. Beispielsweise könnte der gummielastische Körper 14 in verschiedenen Dicken oder Materialien vorgehalten und/oder durch neue Körper 14 ausgetauscht werden. Auch könnten die U-Schenkel der Halterung 13 durch Zwischensetzen (Einkleben) von kleinen Distanzscheibchen verdickt werden. Auch könnte man sich unterschiedlich stark ausgeführte Stifte 7 vorstellen.There are various possibilities conceivable to adapt the friction properties of the fitting during manufacture, as part of the installation or even after wear. For example, the rubber elastic body 14 could be held in different thicknesses or materials and / or replaced by new bodies 14. Also, the U-legs of the bracket 13 could be thickened by Zwischensetzen (gluing) of small spacers. Also, one could imagine differently executed pins 7.

Figur 3 zeigt eine Variante zu den Figuren 1 und 2. Dabei ist in grundsätzlich der gleichen Hohlaufnahme 9 mit der gleichen schrägen Dachfläche 11 statt des U-Profil-Trägers 13 ein längsverschiebliches Element mit einem Keilblock 16 und einem gummielastischen Körper 17 angebracht und geführt. Die nach unten weisende Oberfläche 18 des gummielastischen Körpers 17 ist abgesehen von einer Anschlagsstufe 19 parallel zu der Bewegungsrichtung. Man erkennt also, dass der (zu den Figuren 1 und 2 identische) Stift 7 mit seiner Spitze 8 beim Einfahren spätestens an dem Anschlag 19 "hängen bleibt" und damit das längsverschiebliche Element 16, 17 mitnehmen muss. Der gummielastische Körper 17 kann dazu im Bereich der Anschlagsstufe 19 auf einen Vorsprung des Keilblocks 16 aufgedrückt sein, der diesen Anschlag 19 etwas versteift. FIG. 3 shows a variant of the FIGS. 1 and 2 , In principle, the same hollow seat 9 with the same oblique roof surface 11 instead of the U-profile support 13, a longitudinally displaceable element with a wedge block 16 and a rubber-elastic body 17 is mounted and guided. The downwardly facing surface 18 of the rubber elastic body 17 is apart from a stop step 19 parallel to the direction of movement. One recognizes thus that the (to the FIGS. 1 and 2 identical) pin 7 with its tip 8 when retracting the latest at the stop 19 "gets stuck" and thus the longitudinally displaceable element 16, 17 must take. The rubber-elastic body 17 may be pressed in the area of the stop step 19 on a projection of the wedge block 16, which stiffens this stop 19 something.

Ferner zeigt Figur 3 in der oberen Darstellung auf der linken Seite des längsver schieblichen Elements 16, 17 eine nur angedeutete Feder 20, die das längsverschiebliche Element 16, 17 nach rechts drückt, also in eine "offene" Position. Damit kann sichergestellt werden, dass das längsverschiebliche Element 16, 17 beim Einfahren des Stifts 7 wirklich in dieser offenen Position und nicht etwa zum Beispiel infolge der Schwerkraft oder mangels vollständiger Mitnahme beim letzten Herausfahrvorgang in einer anderen Position liegt Außerdem kann das Lösen des Stifts 7 erleichtert werden.Further shows FIG. 3 in the upper illustration on the left side of the längsver displaceable element 16, 17 an only indicated spring 20, which presses the longitudinally displaceable element 16, 17 to the right, ie in an "open" position. This can ensure that the longitudinally displaceable element 16, 17 during retraction of the pin 7 is really in this open position and not for example due to gravity or lack of complete entrainment in the last driving out in a different position In addition, the release of the pin 7 is facilitated become.

Darunter ist eine Alternative dargestellt, bei der eine Feder 21 auf der rechten Seite angebracht ist und damit den längsverschieblichen Körper 16, 17 nach links drückt. Damit kann besonders zuverlässig sichergestellt werden, dass vor dem Einfahren auch die gewünschte vollständige Pressung zwischen dem gummielastischen Körper 17 und dem Stift 7 entsteht (der in der unteren Darstellung mit eingezeichnet ist).Below is an alternative shown, in which a spring 21 is mounted on the right side and thus the longitudinally displaceable body 16, 17 presses to the left. This can be particularly reliable to ensure that before entering the desired complete pressure between the rubber-elastic body 17 and the pin 7 is formed (which is shown in the lower illustration).

Beim Lösen kann der Stift dann infolge der Reibung das längsverschiebliche Element 16, 17 ein Stück nach rechts mitziehen, bis sich die Reibung löst.When releasing the pin can then drag due to friction, the longitudinally displaceable element 16, 17 a piece to the right until the friction dissolves.

Figur 4 zeigt ein weitgehend identisches Ausführungsbeispiel, wobei hier jedoch die Federn 20 und 21 durch einstückig angeformte Kunststofffederbeinchen ersetzt sind, die mit 22 und 23 beziffert sind. Diese Federbeinchen dienen eher einer Anschlagdämpfung, die allerdings durch die Federn 20 und 21 ebenfalls erreicht wird. Eine solche Anschlagdämpfung kann auch an beiden Seiten vorgesehen sein. FIG. 4 shows a substantially identical embodiment, in which case, however, the springs 20 and 21 are replaced by integrally molded plastic spring legs, which are numbered 22 and 23. These struts are more of a stop damping, which is also achieved by the springs 20 and 21, however. Such a stop damping can also be provided on both sides.
