Definitions
- the present invention relates to a guide rail assembly for an opening restrictor for a sash of a window, door or the like. Furthermore, the invention relates to an opening limiter with a guide rail assembly according to the invention and a sash arrangement with a sash of a window, a door or the like and a window frame, which is equipped with an opening limiter according to the invention.
- EP 2 674 558 A2 , EP 2 674 559 A2 , EP 2 674 557 A2 and EP 3 489 445 A2 show examples of a guide rail assembly for an opening limiter.
- Opening limiters are devices or fittings for windows, patio doors, doors or the like, by means of which the opening angle of the sash of the window, patio door or door can be limited.
- an opening limiter can have a guide rail, which is mounted in a fitting groove of the sash or the associated frame, with a carriage articulated to a first end of a limiter arm being arranged in the guide rail, which slide can be displaced by the guide rail between a first position, the corresponds to a closed position of the wing, and is slidably guided to a second position corresponding to an open position of the wing.
- the second end of the limiting arm is articulated to the other part of the sash and the frame on which the guide rail is not arranged. So if the guide rail is mounted on the wing, the second end of the limiting arm is articulated on the frame; if, on the other hand, the guide rail is mounted on the frame, the second end of the limiting arm is articulated on the wing.
- the carriage that can be moved in the guide rail is coupled to the sash or the window frame via the limiting arm, the carriage is displaced in the guide rail when the sash is pivoted.
- the guide rail has an end stop against which the carriage abuts when the wing is opened, thereby limiting the maximum opening angle of the door in the desired manner.
- a reversible and in particular elastically deformable damping unit can be provided between the end stop and the carriage, which can be used to prevent the carriage from hitting the end stop unbraked. Rather, such a damping unit can absorb the kinetic energy of the wing so that the carriage does not hit the end stop unbraked.
- the damping unit may deform over time and/or its intended orientation due to its deformability change in the guide rail, which can ultimately lead to the damping unit falling out of the guide rail or being pushed out, so that the carriage can hit the end stop without braking, which entails the damage problem described.
- the invention is therefore based on the object of ensuring that an opening restrictor for a sash of a window, a door or the like has a permanently correct damping function.
- the guide rail assembly thus has a guide rail in which a carriage is arranged, which can be coupled to one end of a limiting arm, the other end of which can be articulated on a sash or on a window frame.
- the carriage is slidably guided by the guide rail between a first position, which corresponds to a closed position of the wing, and a second position, which corresponds to an open position of the wing.
- the guide rail assembly has an end stop which is arranged in the guide rail and which prevents the carriage from being displaced beyond the end stop, so that the displacement path of the carriage in the direction of its second position is limited.
- the guide rail assembly in the guide rail includes a damping unit between the End stop and the carriage, which according to the invention is a reversibly deformable damping element, which can in particular be elastic or viscoelastic, and at least one captively connected to the guide rail holding element, through which the damping element is captively held in the guide rail.
- a damping unit between the End stop and the carriage which according to the invention is a reversibly deformable damping element, which can in particular be elastic or viscoelastic, and at least one captively connected to the guide rail holding element, through which the damping element is captively held in the guide rail.
- the damping unit thus has two different components, namely the damping element on the one hand and the at least one holding element on the other hand, with these components having different functions:
- the damping element serves to absorb energy from the sash when the carriage comes into contact with the damping element when the sash is opened.
- the at least holding element does not serve to absorb energy, but rather to secure the damping element in the guide rail when this is deformed as intended.
- the holding element is thus a kind of safety clip, by means of which the damping element can be held captive in the guide rail even if it is deformed due to the carriage impacting the damping element. Since the holding element is slidably guided in the guide rail, it does not prevent the damping element from being deformed if it is impacted by the carriage.
- the damping element has a first and a second end between which it extends in the longitudinal direction of the guide rail, with the damping unit having a holding element between the two ends of the damping element, preferably approximately in the middle thereof, which is connected to the Damping element is connected.
- the damping element thus forms two damping sections on both sides of the essentially centrally arranged retaining element, one of which comes into contact with the end stop and the other with the carriage when the latter approaches its second position.
- the damping element can thus be made relatively long without the risk of it being pushed out of the guide rail due to deformation, since it is held securely in the guide rail by the holding element.
- the damping element be made of an elastic plastic material and the holding element can also be made of a plastic material, which is however stiffer, than the plastic material of the cushioning element.
- the damping element can be made of a polymer material such as polyurethane, with this polymer material preferably being foamed.
- the material Vulkollan® from the Covestro Group or the material Cellasto® from BASF may be mentioned as examples of materials for the damping element.
- a plastic material with a low coefficient of friction such as PTFE or the like, can be used for the holding element.
- the damping unit is arranged on either side of the center between the two ends of the damping element and preferably has a holding element connected to the damping element in the vicinity of both ends of the damping element.
- the two ends of the cushioning element are thus prevented in each case by a holding element from being pushed out of the guide rail by the carriage, as a result of which a particularly reliable damping function can be ensured.
- damping element between the two ends, preferably in the middle of the same be provided with the damping element connected holding element, so as to prevent that the damping element can bulge in the middle between its two ends of the guide rail.
- a plurality of holding elements for example two, three, four or even more holding elements, can thus be provided along the damping element and connected to it in order to reliably hold the damping element in the guide rail.
- the damping element can thus be made relatively long for the benefit of its damping effect without the risk of it bulging out of the guide rail or being pushed out of the guide rail when the carriage comes into contact with the damping element.
- the guide rail can essentially have the shape of a C-profile when viewed in cross section.
- This C-profile can differ from a U-profile in that it has two freely projecting flanges lying in one plane, the free ends of which define a slot between one another that extends in the longitudinal direction of the guide rail and that passes through the free ends of the standing flanges. Through this slot is the damping element receiving Interior of the guide rail accessible, in which the at least one holding element is held captive by the two flanges. The at least one retaining element is thus held captively in the interior of the guide rail by the flanges of the guide rail that define the slot in question.
- the at least one holding element can have a substantially U-shaped connecting section when viewed in cross section, the outer contour of which is essentially complementary to the inner contour of the guide rail, so that the outer contour of the connecting section thus essentially corresponds to the inner contour of the guide rail, in order to to be guided by this in the longitudinal direction of the guide rail.
- the two flanges of the guide rail partially engage behind the connecting section, so that the retaining element and thus the damping unit cannot become detached from the guide rail. Provision can preferably be made for the two flanges to engage with their free ends in corresponding receiving grooves which are formed on the holding element.
- the at least one holding element has a guide section which extends outwards through the slot of the guide rail and whose width essentially corresponds to the width corresponds to the slot or whose width is slightly smaller than the width of the slot. The holding element is thus guided in the slot by means of the guide section in question.
- the guide section in question covers the two flanges of the guide rail viewed from the interior of the same.
- the guide section, together with the connecting section of the holding element, can form corresponding receiving grooves for the two flanges of the guide rail, as a result of which it can be prevented in a particularly reliable manner that the holding element becomes detached from the guide rail.
- each of the flanges of the guide rail has an outer surface which is inclined in such a way that the respective flange tapers towards its free end.
- the section of the guide section with which it engages behind the respective flange can have a guide surface running parallel to the outer surface of the respective flange, so that the guide section has a substantially dovetail shape when viewed in cross section. This ensures that the holding element and in particular its guide section does not protrude beyond the outer contour of the guide rail, which could otherwise lead to the free mobility of the holding element in the longitudinal direction of the rail being impaired by adjacent components such as a sash or a window frame.
- the damping element has an indented section for each holding element which, compared to the damping sections, has a reduced cross section between these indented sections, which Retaining element and is fitted in particular in the U-shaped connecting portion.
- the connecting portion of the retaining element is, for example, U-shaped or fork-like in cross-section, this connecting portion can accommodate the indented portion in question with a reduced cross-section in such a way that the connecting portion with the adjacent damping sections of the damping element is substantially flush.
- an opening restrictor comprising a guide track assembly as hereinbefore described, wherein the carriage is pivoted to a first end of a restrictor arm, the second end of which engages a sash of a window, door or the like or an articulated frame.
- a sash assembly is provided with a sash of a window, door or the like and a frame relative to which the sash can be pivoted, this sash assembly comprising the opening restrictor described above, the guide rail of which is in a fitting groove of the sash or of the frame, the second end of the limiter arm being pivoted to that part of the sash assembly where the guide rail is not located.
- FIGS. 1 and 2 show a wing assembly 10 according to the invention, the only schematically indicated wing 12 in the 1 in a relative to the frame 14 (also only indicated schematically) of the wing assembly 10 is partially open position.
- the 2 the casement arrangement 10 with the casement 12 fully open which can be, for example, a window which can be pivoted relative to the frame 14 or a door or balcony door which can be pivoted relative to the frame 14 .
- the guide rail 22 of the opening limiter 20 is arranged and mounted in a fitting groove on the underside of the sash 12, whereas the second end of the limiter arm 24 is connected to the frame 14 in an articulated manner.
- the guide rail 22 could also be arranged on the window frame 14 and the second end of the limiting arm 24 could be connected to the sash 12 in an articulated manner.
- the guide rail 22 has a substantially C-shaped cross-sectional profile (see in particular the 6 ) defining an interior space 40 in which is disposed a carriage 26 slidably guided by the guide rail 22 between a first position corresponding to a closed position of the wing 12 and a second position corresponding to an open position of the wing corresponds, as in the 2 is shown.
- An end stop 28 is arranged in the same at both ends of the guide rail 22 and is firmly connected to the guide rail 22, which prevents displacement of the carriage 26 beyond the respective end stop 28. Therefore, the wing 12 starting from its closed position on the intermediate position 1 out to its fully open position 2 pivoted, the carriage 26, being articulated to the first end of the limiter arm 24, is displaced from its first position, corresponding to the closed position of the leaf 12, to its second position, corresponding to the open position of the leaf 12 corresponds.
- the carriage 26 hits a reversibly deformable damping unit 30 which is arranged in the interior 40 of the guide rail 22 between the end stop 28 which is associated with the second position of the carriage 26 and the carriage 26 .
- the carriage 26 thus does not collide directly against the end stop 28 in question, which could lead to damage to the opening limiter 20 over time; Rather, the carriage 26 comes into contact with the damping unit 30, which is arranged between the carriage 26 and the end stop 28, so that the kinetic energy of the wing 12 is at least partially absorbed by the damping unit 30.
- the damping unit 30 according to the invention is not a one-piece body; Rather, the damping unit 30 consists of two different components, namely on the one hand a reversibly deformable damping element 32 and on the other hand at least one or more retaining elements 34 which can be detachably or non-detachably connected to the damping element 32 .
- a total of three holding elements 34 are provided, which are connected to the damping element 32, as will be explained in more detail below.
- the damping element 32 is an elongate or elongate body made of an elastic or viscoelastic plastic material, such as a foamed polymer material (e.g. Vulkollan ® from the Covestro Group or Cellasto ® from BASF), which has a indented or constricted portion 50 has.
- foamed polymer material e.g. Vulkollan ® from the Covestro Group or Cellasto ® from BASF
- These indented sections 50 have a reduced cross-section compared to the intermediate or adjacent damping sections 52, so that the individual retaining elements 34 can be fitted in the area of these indented sections 50 without these elements 34 protruding laterally beyond the contour of the damping sections 52, see for this the 4 .
- the holding elements 34 are made of a stiffer material than the damping element 32 and can be made of PTFE, for example.
- the holding elements 34 have a substantially U-shaped connecting section 42 (see the Figures 5 and 6 ), which is shaped in such a way that its outer contour essentially corresponds to the inner contour of the guide rail 22 in order to be able to be guided by it, see the 6 .
- the outer contour of the U-shaped connecting section 42 is therefore matched to the inner contour of the guide rail 22 so that the holding elements 34 can slide along the guide rail 22, which is favored by the formation of the holding elements 34 from low-friction PTFE.
- the U-shaped connecting section 42 of the holding elements 34 merges into a guide section 46 in one piece, with two opposing receiving grooves 34 being formed in the guide section 46, in which the two flanges 36 of the guide rail 22 engage.
- the flanges 36 in question define between their free ends a slot 38 extending in the longitudinal direction of the guide rail, through which the holding element 34 extends from the inner space 40 of the guide rail 22 to the outside.
- the width of the guide section 46 in the region of the slot 38 in question essentially corresponds to the width of the slot 38 .
- the holding elements 34 and thus also the damping unit 30 are captive in their entirety in the Guide rail 22 held.
- the damping element 32 is thus captively held in the guide rail 22 by means of the holding elements 34 .
- the guide section 46 has a substantially dovetail shape, which is matched to the shape of the guide rail 22 and in particular to the shape of the two flanges 36 of the guide rail 22 such that the two flanges 36 can be seen from the interior 40 of the guide rail 22 viewed from behind by the guide section 46 .
- each of the flanges 36 of the guide rail 22 has an outer surface 48 which is inclined in such a way that the respective flange 36 tapers towards its free end. Due to the dovetail shape of the guide section 46, it therefore has a guide surface 54 running parallel to the outer surface 48 of the respective flange 36, which not only allows the holding elements 34 to be guided particularly reliably along the flange 36, but also ensures in particular that the holding elements 34 do not protrude with their guide sections 46 over the outer contour of the guide rail 22.
- the retaining elements 34 ensure that it cannot be pushed out of the interior space 40 of the guide rail 22 .
- This is prevented in a particularly reliable manner in that, in the embodiment shown here, the damping element 32 is secured in the guide rail 22 by means of three holding elements 34:
- the middle holding element 34 prevents the damping element 32 from buckling or bulging outwards in the middle can, whereas the two other holding elements 34, which are arranged in the vicinity of the two ends of the cushioning element 42, can prevent the two ends of the cushioning element 32 from bulging out of the interior 40 of the guide rail 22 when the cushioning unit 30 is compressed in its entirety by the carriage 26 as a result of an impact.

Description
Die vorliegende Erfindung betrifft eine Führungsschienenbaugruppe für einen Öffnungsbegrenzer für einen Flügel eines Fensters, einer Tür oder dergleichen. Ferner betrifft die Erfindung einen Öffnungsbegrenzer mit einer erfindungsgemäßen Führungsschienenbaugruppe sowie eine Flügelanordnung mit einem Flügel eines Fensters, einer Tür oder dergleichen und einem Blendrahmen, die mit einem erfindungsgemäßen Öffnungsbegrenzer ausgestattet ist.The present invention relates to a guide rail assembly for an opening restrictor for a sash of a window, door or the like. Furthermore, the invention relates to an opening limiter with a guide rail assembly according to the invention and a sash arrangement with a sash of a window, a door or the like and a window frame, which is equipped with an opening limiter according to the invention.
Öffnungsbegrenzer sind Vorrichtungen bzw. Beschlagteile für Fenster, Fenstertüren, Türen oder dergleichen, mittels derer sich der Öffnungswinkel des Flügels des Fensters, der Fenstertür oder der Tür begrenzen lässt. Hierzu kann solch ein Öffnungsbegrenzer eine Führungsschiene aufweisen, die in einer Beschlagnut des Flügels oder des zugehörigen Blendrahmens montiert ist, wobei in der Führungsschiene ein mit einem ersten Ende eines Begrenzungsarms gelenkig gekoppelter Schlitten angeordnet ist, der durch die Führungsschiene verschiebbar zwischen einer ersten Position, die einer geschlossenen Position des Flügels entspricht, und einer zweiten Position verschiebbar geführt ist, die einer geöffneten Stellung des Flügels entspricht. Das zweite Ende des Begrenzungsarms ist dabei mit dem anderen Teil des Flügels und des Blendrahmens gelenkig verbunden, an dem die Führungsschiene nicht angeordnet ist. Ist also die Führungsschiene am Flügel montiert, so ist das zweite Ende des Begrenzungsarms am Blendrahmen angelenkt; ist hingegen die Führungsschiene am Blendrahmen montiert, so ist das zweite Ende des Begrenzungsarms am Flügel angelenkt.Opening limiters are devices or fittings for windows, patio doors, doors or the like, by means of which the opening angle of the sash of the window, patio door or door can be limited. For this purpose, such an opening limiter can have a guide rail, which is mounted in a fitting groove of the sash or the associated frame, with a carriage articulated to a first end of a limiter arm being arranged in the guide rail, which slide can be displaced by the guide rail between a first position, the corresponds to a closed position of the wing, and is slidably guided to a second position corresponding to an open position of the wing. The second end of the limiting arm is articulated to the other part of the sash and the frame on which the guide rail is not arranged. So if the guide rail is mounted on the wing, the second end of the limiting arm is articulated on the frame; if, on the other hand, the guide rail is mounted on the frame, the second end of the limiting arm is articulated on the wing.
Da der in der Führungsschiene verfahrbare Schlitten über den Begrenzungsarm mit dem Flügel oder dem Blendrahmen gekoppelt ist, wird der Schlitten in der Führungsschiene verschoben, wenn der Flügel verschwenkt wird.Since the carriage that can be moved in the guide rail is coupled to the sash or the window frame via the limiting arm, the carriage is displaced in the guide rail when the sash is pivoted.
Um den Öffnungswinkel des Flügels zu begrenzen, weist die Führungsschiene einen Endanschlag auf, an der der Schlitten anstößt, wenn der Flügel geöffnet wird, wodurch der maximale Öffnungswinkel der Tür in der gewünschten Weise begrenzt wird.In order to limit the opening angle of the wing, the guide rail has an end stop against which the carriage abuts when the wing is opened, thereby limiting the maximum opening angle of the door in the desired manner.
Prallt jedoch der Schlitten in der zuvor beschriebenen Art und Weise ungebremst an den Endanschlag an, so kann es unter Umständen zu einer unerwünschten Beschädigung des Öffnungsbegrenzers sowie weiterer Beschlagteile des Flügels kommen. Insbesondere dann, wenn beispielsweise der Flügel durch eine Windböe schwungvoll aufgestoßen wird, kann es vorkommen, dass der Schlitten mit voller Wucht an den Endanschlag prall, was zu einer Beschädigung des Öffnungsbegrenzers führen kann.However, if the carriage hits the end stop without braking in the manner described above, undesired damage to the opening restrictor and other fittings of the sash may occur under certain circumstances. Especially when, for example, the sash is pushed open by a gust of wind, it can happen that the carriage hits the end stop with full force, which can lead to damage to the opening restrictor.
Um solch einer Beschädigung zuvorzukommen, kann eine reversibel und insbesondere elastisch verformbare Dämpfungseinheit zwischen dem Endanschlag und dem Schlitten vorgesehen sein, durch die verhindert werden kann, dass der Schlitten ungebremst auf den Endanschlag prallt. Vielmehr kann solch eine Dämpfungseinheit die kinetische Energie des Flügels absorbieren, so dass der Schlitten nicht ungebremst gegen den Endanschlag prallt.In order to prevent such damage, a reversible and in particular elastically deformable damping unit can be provided between the end stop and the carriage, which can be used to prevent the carriage from hitting the end stop unbraked. Rather, such a damping unit can absorb the kinetic energy of the wing so that the carriage does not hit the end stop unbraked.
Da jedoch der Schlitten jedes Mal dann, wenn der Flügel vollständig geöffnet wird, auf die Dämpfungseinheit trifft, kann sich die Dämpfungseinheit mit der Zeit verformen und/oder aufgrund ihrer Verformbarkeit ihre bestimmungsgemäße Ausrichtung in der Führungsschiene verändern, was letztendlich dazu führen kann, dass die Dämpfungseinheit aus der Führungsschiene herausfällt oder herausgedrückt wird, so dass der Schlitten ungebremst gegen den Endanschlag prallen kann, was die beschriebene Beschädigungsproblematik nach sich zieht.However, since the carriage hits the damping unit each time the wing is fully opened, the damping unit may deform over time and/or its intended orientation due to its deformability change in the guide rail, which can ultimately lead to the damping unit falling out of the guide rail or being pushed out, so that the carriage can hit the end stop without braking, which entails the damage problem described.
Der Erfindung liegt daher die Aufgabe zugrunde, für eine dauerhaft ordnungsgemäße Dämpfungsfunktion eines Öffnungsbegrenzers für einen Flügel eines Fensters, einer Tür oder dergleichen zu sorgen.The invention is therefore based on the object of ensuring that an opening restrictor for a sash of a window, a door or the like has a permanently correct damping function.
Diese Aufgabe wird mit einer Führungsschienenbaugruppe mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with a guide rail assembly having the features of
Die erfindungsgemäße Führungsschienenbaugruppe weist somit eine Führungsschiene auf, in der ein Schlitten angeordnet ist, der mit einem Ende eines Begrenzungsarms gekoppelt werden kann, dessen anderes Ende an einem Flügel oder an einem Blendrahmen angelenkt werden kann. Der Schlitten ist dabei durch die Führungsschiene verschiebbar zwischen einer ersten Position, die einer geschlossenen Stellung des Flügels entspricht, und einer zweiten Position verschiebbar geführt, die einer geöffneten Stellung des Flügels entspricht. Des Weiteren verfügt die Führungsschienenbaugruppe über einen Endanschlag, der in der Führungsschiene angeordnet ist und der eine Verschiebung des Schlittens über den Endanschlag hinaus verhindert, so dass der Verschiebeweg des Schlittens in Richtung seiner zweiten Position begrenzt ist. Des Weiteren umfasst die Führungsschienenbaugruppe in der Führungsschiene eine Dämpfungseinheit zwischen dem Endanschlag und dem Schlitten, welche erfindungsgemäß ein reversibel verformbares Dämpfungselement, welches insbesondere elastisch oder viskoelastisch sein kann, und zumindest ein verliersicher mit der Führungsschiene verbundenes Halteelement, durch das das Dämpfungselement verliersicher in der Führungsschiene gehalten ist.The guide rail assembly according to the invention thus has a guide rail in which a carriage is arranged, which can be coupled to one end of a limiting arm, the other end of which can be articulated on a sash or on a window frame. The carriage is slidably guided by the guide rail between a first position, which corresponds to a closed position of the wing, and a second position, which corresponds to an open position of the wing. Furthermore, the guide rail assembly has an end stop which is arranged in the guide rail and which prevents the carriage from being displaced beyond the end stop, so that the displacement path of the carriage in the direction of its second position is limited. Furthermore, the guide rail assembly in the guide rail includes a damping unit between the End stop and the carriage, which according to the invention is a reversibly deformable damping element, which can in particular be elastic or viscoelastic, and at least one captively connected to the guide rail holding element, through which the damping element is captively held in the guide rail.
Die Dämpfungseinheit weist somit zwei unterschiedliche Komponenten auf, nämlich das Dämpfungselement einerseits und das zumindest eine Halteelement andererseits, wobei diesen Komponenten unterschiedliche Funktionen zukommen: So dient das Dämpfungselement der Energieabsorption des Flügels, wenn der Schlitten beim Öffnen des Flügels mit dem Dämpfungselement in Anlage gelangt. Demgegenüber dient das zumindest Halteelement nicht der Energieabsorption, sondern der Sicherung des Dämpfungselements in der Führungsschiene, wenn sich dieses bestimmungsgemäß verformt. Bei dem Halteelement handelt es sich somit gewissermaßen um eine Art Sicherungsklammer, mittels derer sich das Dämpfungselement verliersicher in der Führungsschiene selbst dann halten lässt, wenn sich dieses aufgrund eines Anpralls des Schlittens an dem Dämpfungselement verformt. Da das Halteelement verschiebbar in der Führungsschiene geführt ist, behindert dieses nicht eine Verformung des Dämpfungselements, wenn dieses einen Aufprall durch den Schlitten erfährt.The damping unit thus has two different components, namely the damping element on the one hand and the at least one holding element on the other hand, with these components having different functions: The damping element serves to absorb energy from the sash when the carriage comes into contact with the damping element when the sash is opened. In contrast, the at least holding element does not serve to absorb energy, but rather to secure the damping element in the guide rail when this is deformed as intended. The holding element is thus a kind of safety clip, by means of which the damping element can be held captive in the guide rail even if it is deformed due to the carriage impacting the damping element. Since the holding element is slidably guided in the guide rail, it does not prevent the damping element from being deformed if it is impacted by the carriage.
Erfindungsgemäß ist es vorgesehen, dass das Dämpfungselement ein erstes und ein zweites Ende aufweist, zwischen denen es sich in Längsrichtung der Führungsschiene erstreckt, wobei die Dämpfungseinheit zwischen den beiden Enden des Dämpfungselements und zwar vorzugsweise etwa in der Mitte desselben ein Halteelement aufweist, das mit dem Dämpfungselement verbunden ist. Das Dämpfungselement bildet somit also beiderseits des im Wesentlichen mittig angeordneten Halteelements zwei Dämpfungsabschnitte aus, von denen der eine mit dem Endanschlag und der andere mit dem Schlitten in Anlage gelangt, wenn sich dieser seiner zweiten Position nähert. Das Dämpfungselement kann somit verhältnismäßig lang ausgebildet werden, ohne dass die Gefahr besteht, dass es verformungsbedingt aus der Führungsschiene herausgedrückt wird, da es durch das Halteelement in der Führungsschiene sicher gehalten wird.According to the invention, it is provided that the damping element has a first and a second end between which it extends in the longitudinal direction of the guide rail, with the damping unit having a holding element between the two ends of the damping element, preferably approximately in the middle thereof, which is connected to the Damping element is connected. The damping element thus forms two damping sections on both sides of the essentially centrally arranged retaining element, one of which comes into contact with the end stop and the other with the carriage when the latter approaches its second position. The damping element can thus be made relatively long without the risk of it being pushed out of the guide rail due to deformation, since it is held securely in the guide rail by the holding element.
Im Folgenden wird nun auf bevorzugte Ausführungsformen der Erfindung eingegangen. Weitere Ausführungsformen können sich auch aus den abhängigen Ansprüchen, der Figurenbeschreibung sowie den Zeichnungen ergeben.Preferred embodiments of the invention will now be discussed below. Further embodiments can also result from the dependent claims, the description of the figures and the drawings.
So kann das Dämpfungselement gemäß einer Ausführungsform beispielsweise aus einem elastischen Kunststoffmaterial gefertigt sein und auch das Halteelement kann aus einem Kunststoffmaterial gefertigt sein, welches jedoch steifer ist, als das Kunststoffmaterial des Dämpfungselements. Beispielsweise kann das Dämpfungselement aus einem Polymermaterial wie beispielsweise Polyurethan gefertigt sein, wobei dieses Polymermaterial vorzugsweise aufgeschäumt sein kann. Als beispielhafte Materialien für das Dämpfungselement sei beispielsweise der Werkstoff Vulkollan® der Covestro Gruppe oder der Werkstoff Cellasto® von BASF angeführt. Demgegenüber kann für das Halteelement ein Kunststoffmaterial mit geringem Reibkoeffizienten wie beispielsweise PTFE oder dergleichen zum Einsatz kommen.For example, according to one embodiment, the damping element be made of an elastic plastic material and the holding element can also be made of a plastic material, which is however stiffer, than the plastic material of the cushioning element. For example, the damping element can be made of a polymer material such as polyurethane, with this polymer material preferably being foamed. The material Vulkollan® from the Covestro Group or the material Cellasto® from BASF may be mentioned as examples of materials for the damping element. In contrast, a plastic material with a low coefficient of friction, such as PTFE or the like, can be used for the holding element.
Um zu verhindern, dass eines oder beide Enden des Dämpfungselements aus der Führungsschiene herausgedrückt werden, wenn der Schlitten mit dem Dämpfungselement in Anlage gelangt, kann es gemäß einer weiteren Ausführungsform vorgesehen sein, dass die Dämpfungseinheit beiderseits der Mitte zwischen den beiden Enden des Dämpfungselements und vorzugsweise in der Nähe der beiden Enden des Dämpfungselements jeweils ein mit dem Dämpfungselement verbundenes Halteelement aufweist. Die beiden Enden des Dämpfungselements werden somit jeweils durch ein Halteelement daran gehindert, durch den Schlitten aus der Führungsschiene herausgedrückt zu werden, wodurch eine besonders zuverlässige Dämpfungsfunktion sichergestellt werden kann.In order to prevent one or both ends of the damping element from being pushed out of the guide rail when the carriage comes into contact with the damping element, it can be provided according to a further embodiment that the damping unit is arranged on either side of the center between the two ends of the damping element and preferably has a holding element connected to the damping element in the vicinity of both ends of the damping element. The two ends of the cushioning element are thus prevented in each case by a holding element from being pushed out of the guide rail by the carriage, as a result of which a particularly reliable damping function can be ensured.
Um zu verhindern, dass sich das Dämpfungselement etwa in der Mitte zwischen seinen beiden Enden aus der Führungsschiene herauswölbt, wenn der Schlitten infolge des Öffnens eines Flügels auf das Dämpfungselement trifft, ist erfindungsgemäß zwischen den beiden Enden des Dämpfungselements und zwar vorzugsweise in der Mitte desselben ein mit dem Dämpfungselement verbundenes Halteelement vorgesehen sein, um so zu verhindern, dass sich das Dämpfungselement in der Mitte zwischen seinen beiden Enden aus der Führungsschiene herauswölben kann.In order to prevent the damping element from bulging out of the guide rail approximately in the middle between its two ends when the carriage hits the damping element as a result of the opening of a leaf, according to the invention there is a damping element between the two ends, preferably in the middle of the same be provided with the damping element connected holding element, so as to prevent that the damping element can bulge in the middle between its two ends of the guide rail.
Es können somit mehrere Halteelemente, beispielsweise zwei, drei, vier oder noch mehr Halteelemente entlang des Dämpfungselements vorgesehen und mit demselben verbunden sein, um so das Dämpfungselement zuverlässig in der Führungsschiene zu halten. Das Dämpfungselement kann somit zugunsten seiner Dämpfungswirkung verhältnismäßig lang ausgebildet werden, ohne dass dabei die Gefahr besteht, dass es sich aus der Führungsschiene herauswölben bzw. aus der Führungsschiene herausgedrückt werden kann, wenn der Schlitten mit dem Dämpfungselement in Anlage gelangt.A plurality of holding elements, for example two, three, four or even more holding elements, can thus be provided along the damping element and connected to it in order to reliably hold the damping element in the guide rail. The damping element can thus be made relatively long for the benefit of its damping effect without the risk of it bulging out of the guide rail or being pushed out of the guide rail when the carriage comes into contact with the damping element.
Gemäß einer weiteren Ausführungsform kann die Führungsschiene im Querschnitt betrachtet im Wesentlichen die Gestalt eines C-Profils aufweisen. Dieses C-Profil kann sich von einem U-Profil insoweit unterscheiden, dass es zwei frei auskragende und in einer Ebene liegende Flansche aufweist, deren freie Enden zwischen einander einen sich in Längsrichtung der Führungsschiene erstreckenden Schlitz definieren, der durch die freien Enden der in Rede stehenden Flansche begrenzt wird. Durch diesen Schlitz ist der das Dämpfungselement aufnehmende Innenraum der Führungsschiene zugänglich, in dem das zumindest eine Halteelement durch die beiden Flansche verliersicher gehalten ist. Durch die den in Rede stehenden Schlitz definierenden Flansche der Führungsschiene wird das zumindest eine Halteelement somit im Innenraum der Führungsschiene verliersicher gehalten.According to a further embodiment, the guide rail can essentially have the shape of a C-profile when viewed in cross section. This C-profile can differ from a U-profile in that it has two freely projecting flanges lying in one plane, the free ends of which define a slot between one another that extends in the longitudinal direction of the guide rail and that passes through the free ends of the standing flanges. Through this slot is the damping element receiving Interior of the guide rail accessible, in which the at least one holding element is held captive by the two flanges. The at least one retaining element is thus held captively in the interior of the guide rail by the flanges of the guide rail that define the slot in question.
Gemäß einer anderen Ausführungsform kann das zumindest eine Halteelement im Querschnitt betrachtet einen im Wesentlichen U-förmigen Verbindungsabschnitt aufweisen, dessen Außenkontur im Wesentlichen komplementär auf die Innenkontur der Führungsschiene abgestimmt ist, so dass die Außenkontur des Verbindungsabschnitts der Innenkontur der Führungsschiene somit im Wesentlichen entspricht, um von dieser in Längsrichtung der Führungsschiene geführt zu werden. Die beiden Flansche der Führungsschiene hintergreifen dabei vom Innenraum der Führungsschiene aus betrachtet den Verbindungsabschnitt teilweise, so dass sich das Halteelement und damit die Dämpfungseinheit nicht aus der Führungsschiene lösen kann. Vorzugsweise kann es dabei vorgesehen sein, dass die beiden Flansche mit ihren freien Enden in entsprechende Aufnahmenuten eingreifen, die an dem Halteelement ausgebildet sind.According to another embodiment, the at least one holding element can have a substantially U-shaped connecting section when viewed in cross section, the outer contour of which is essentially complementary to the inner contour of the guide rail, so that the outer contour of the connecting section thus essentially corresponds to the inner contour of the guide rail, in order to to be guided by this in the longitudinal direction of the guide rail. Viewed from the interior of the guide rail, the two flanges of the guide rail partially engage behind the connecting section, so that the retaining element and thus the damping unit cannot become detached from the guide rail. Provision can preferably be made for the two flanges to engage with their free ends in corresponding receiving grooves which are formed on the holding element.
Um für eine besonders zuverlässige Führung der Dämpfungseinheit in Längsrichtung der Führungsschiene zu sorgen, kann es gemäß einer weiteren Ausführungsform vorgesehen sein, dass das zumindest eine Halteelement einen Führungsabschnitt aufweist, der sich durch den Schlitz der Führungsschiene nach außen erstreckt und dessen Breite im Wesentlichen der Breite des Schlitzes entspricht bzw. dessen Breite geringfügig kleiner als die Breite des Schlitzes ist. Das Halteelement ist somit mittels des in Rede stehenden Führungsabschnitts in dem Schlitz geführt.In order to ensure a particularly reliable guidance of the damping unit in the longitudinal direction of the guide rail, it can be provided according to a further embodiment that the at least one holding element has a guide section which extends outwards through the slot of the guide rail and whose width essentially corresponds to the width corresponds to the slot or whose width is slightly smaller than the width of the slot. The holding element is thus guided in the slot by means of the guide section in question.
Gemäß einer bevorzugten Ausführungsform kann es dabei vorgesehen sein, dass der in Rede stehende Führungsabschnitt die beiden Flansche der Führungsschiene vom Innenraum derselben aus betrachtet hintergreift. Der Führungsabschnitt kann dabei zusammen mit dem Verbindungsabschnitt des Halteelements entsprechende Aufnahmenuten für die beiden Flansche der Führungsschiene bilden, wodurch besonders zuverlässig verhindert werden kann, dass sich das Halteelement aus der Führungsschiene löst.According to a preferred embodiment, it can be provided that the guide section in question covers the two flanges of the guide rail viewed from the interior of the same. The guide section, together with the connecting section of the holding element, can form corresponding receiving grooves for the two flanges of the guide rail, as a result of which it can be prevented in a particularly reliable manner that the holding element becomes detached from the guide rail.
Gemäß noch einer weiteren Ausführungsform kann es vorgesehen sein, dass jeder der Flansche der Führungsschiene eine Außenfläche aufweist, die derart geneigt ist, dass sich der jeweilige Flansch in Richtung seines freien Endes hin verjüngt. Hierbei kann jener Abschnitt des Führungsabschnitts, mit dem dieser den jeweiligen Flansch hintergreift, eine parallel zu der Außenfläche des jeweiligen Flansches verlaufende Führungsfläche aufweisen, sodass der Führungsabschnitt im Querschnitt betrachtet eine im Wesentlichen schwalbenschwanzförmige Gestalt aufweist. Hierdurch gelingt es, dass das Halteelement und insbesondere dessen Führungsabschnitt nicht über die äußere Kontur der Führungsschiene übersteht, was andernfalls dazu führen könnte, dass die freie Beweglichkeit des Halteelements in Längsrichtung der Schiene durch angrenzende Bauteile wie beispielsweise einen Flügel oder einen Blendrahmen beeinträchtigt wird.According to yet another embodiment, it can be provided that each of the flanges of the guide rail has an outer surface which is inclined in such a way that the respective flange tapers towards its free end. The section of the guide section with which it engages behind the respective flange can have a guide surface running parallel to the outer surface of the respective flange, so that the guide section has a substantially dovetail shape when viewed in cross section. This ensures that the holding element and in particular its guide section does not protrude beyond the outer contour of the guide rail, which could otherwise lead to the free mobility of the holding element in the longitudinal direction of the rail being impaired by adjacent components such as a sash or a window frame.
Um das zumindest eine Halteelement an dem Dämpfungselement sichern zu können, kann es gemäß einer weiteren Ausführungsform vorgesehen sein, dass das Dämpfungselement für jedes Halteelement einen eingebuchteten Abschnitt aufweist, der im Vergleich zu den Dämpfungsabschnitten zwischen diesen eingebuchteten Abschnitten einen reduzierten Querschnitt aufweist, der in das Halteelement und insbesondere in dessen U-förmigen Verbindungsabschnitt eingepasst ist. Weist der Verbindungsabschnitt des Halteelements im Querschnitt betrachtet beispielsweise eine U-förmige oder gabelartige Gestalt auf, so kann dieser Verbindungsabschnitt den in Rede stehenden eingebuchteten Abschnitt mit reduziertem Querschnitt derart aufnehmen, dass der Verbindungsabschnitt mit den benachbarten Dämpfungsabschnitten des Dämpfungselements im Wesentlichen bündig ist.In order to be able to secure the at least one holding element on the damping element, it can be provided according to a further embodiment that the damping element has an indented section for each holding element which, compared to the damping sections, has a reduced cross section between these indented sections, which Retaining element and is fitted in particular in the U-shaped connecting portion. If the connecting portion of the retaining element is, for example, U-shaped or fork-like in cross-section, this connecting portion can accommodate the indented portion in question with a reduced cross-section in such a way that the connecting portion with the adjacent damping sections of the damping element is substantially flush.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung wird ein Öffnungsbegrenzer geschaffen, welcher eine Führungsschienenbaugruppe umfasst, wie sie zuvor beschrieben wurde, wobei der Schlitten mit einem ersten Ende eines Begrenzungsarms gelenkig verbunden ist, dessen zweites Ende sich mit einem Flügel eines Fensters, einer Tür oder dergleichen oder einem Blendrahmen gelenkig verbinden lässt.According to a further aspect of the present invention there is provided an opening restrictor comprising a guide track assembly as hereinbefore described, wherein the carriage is pivoted to a first end of a restrictor arm, the second end of which engages a sash of a window, door or the like or an articulated frame.
Gemäß noch einem weiteren Aspekt der vorliegenden Erfindung wird eine Flügelanordnung mit einem Flügel eines Fensters, einer Tür oder dergleichen und einem Blendrahmen geschaffen, bezüglich dessen der Flügel verschwenkbar ist, wobei diese Flügelanordnung den zuvor beschriebenen Öffnungsbegrenzer umfasst, dessen Führungsschiene in einer Beschlagnut des Flügels oder des Blendrahmens angeordnet ist, wobei das zweite Ende des Begrenzungsarms mit jenem Teil der Flügelanordnung gelenkig verbunden ist, an dem die Führungsschiene nicht angeordnet ist.According to yet another aspect of the present invention, a sash assembly is provided with a sash of a window, door or the like and a frame relative to which the sash can be pivoted, this sash assembly comprising the opening restrictor described above, the guide rail of which is in a fitting groove of the sash or of the frame, the second end of the limiter arm being pivoted to that part of the sash assembly where the guide rail is not located.

Grundsätzlich handelt es sich bei dem Dämpfungselement 32 um einen langgestreckten bzw. länglichen Körper aus einem elastischen oder viskoelastischen Kunststoffmaterial, wie beispielsweise aus einem aufgeschäumten Polymermaterial (bspw. Vulkollan® der Covestro Gruppe oder Cellasto® von BASF), das zur Aufnahme jedes Halteelements 34 einen eingebuchteten oder eingeschnürten Abschnitt 50 aufweist. Diese eingebuchteten Abschnitte 50 weisen im Vergleich zu den dazwischenliegenden oder angrenzenden Dämpfungsabschnitten 52 einen reduzierten Querschnitt auf, so dass im Bereich dieser eingebuchteten Abschnitte 50 die einzelnen Halteelemente 34 eingepasst werden können, ohne dass diese Elemente 34 seitlich über die Kontur der Dämpfungsabschnitte 52 überstehen, siehe hierzu die
Die Halteelemente 34 weisen einen im Wesentlichen U-förmigen Verbindungsabschnitt 42 auf (siehe hierzu die
An seinem geschlossenen Ende geht der U-förmige Verbindungsabschnitt 42 der Halteelemente 34 jeweils in einen Führungsabschnitt 46 einstückig über, wobei in dem Führungsabschnitt 46 zwei einander gegenüberliegende Aufnahmenuten 34 ausgebildet sind, in die die beiden Flansche 36 der Führungsschiene 22 eingreifen. Die in Rede stehenden Flansche 36 definieren zwischen ihren freien Enden einen sich in Längsrichtung der Führungsschiene erstreckenden Schlitz 38, durch den sich das Halteelement 34 vom Innenraum 40 der Führungsschiene 22 nach außen erstreckt. Der Führungsabschnitt 46 weist dabei im Bereich des in Rede stehenden Schlitzes 38 eine Breite auf, die im Wesentlichen der Breite des Schlitzes 38 entspricht. Dadurch, dass die Flansche 36 der Führungsschiene 22 in die beiderseits der Halteelemente 34 ausgebildeten Aufnahmenuten 44 eingreifen und somit den Verbindungsabschnitt 42 vom Innenraum 46 der Führungsschiene 22 aus betrachtet hintergreifen, sind die Halteelemente 34 und damit auch die Dämpfungseinheit 30 in ihrer Gesamtheit verliersicher in der Führungsschiene 22 gehalten. Das Dämpfungselement 32 ist somit mittels der Halteelemente 34 verliersicher in der Führungsschiene 22 gehalten.At its closed end, the U-shaped connecting
Wie den
Bei der konkret dargestellten Ausführungsform weist jeder der Flansche 36 der Führungsschiene 22 eine Außenfläche 48 auf, welche derart geneigt ist, dass sich der jeweilige Flansch 36 in Richtung seines freien Endes hin verjüngt. Aufgrund der schwalbenschwanzförmigen Gestalt des Führungsabschnitts 46 weist dieser somit eine parallel zu der Außenfläche 48 des jeweiligen Flansches 36 verlaufende Führungsfläche 54 auf, wodurch nicht nur eine besonders zuverlässige Führung der Halteelemente 34 entlang der Flansche 36, sondern insbesondere auch sichergestellt werden kann, dass die Halteelemente 34 mit ihren Führungsabschnitten 46 nicht über die äußere Kontur der Führungsschiene 22 überstehen.In the embodiment specifically illustrated, each of the
Wird nun das Dämpfungselement 32 infolge eines Aufpralls des Schlittens 26 in Längsrichtung der Führungsschiene 22 komprimiert, so wird diese Komprimierung des Dämpfungselements 32 durch die Halteelemente 34 nicht beeinträchtigt, da die Halteelemente 34 infolge einer Komprimierung des Dämpfungselements 32 in Längsrichtung der Führungsschiene 22 verschoben werden können.If the damping
Vielmehr sorgen die Halteelemente 34 bei einer Komprimierung des Dämpfungselements 32 dafür, dass dieses nicht aus dem Innenraum 40 der Führungsschiene 22 herausgedrückt werden kann. Dies wird besonders zuverlässig dadurch verhindert, dass bei der hier dargestellten Ausführungsform das Dämpfungselement 32 mittels dreier Halteelemente 34 in der Führungsschiene 22 gesichert ist: Durch das mittlere Halteelemente 34 wird dabei verhindert, dass das Dämpfungselement 32 in der Mitte nicht nach außen knicken bzw. wölben kann, wohingegen durch die beiden anderen Halteelemente 34, die in der Nähe der beiden Enden des Dämpfungselements 42 angeordnet sind, verhindert werden kann, dass die beiden Enden des Dämpfungselements 32 sich nicht aus dem Innenraum 40 der Führungsschiene 22 nach außen wölben, wenn die Dämpfungseinheit 30 in ihrer Gesamtheit infolge eines Aufpralls durch den Schlitten 26 komprimiert wird.Rather, when the damping
