Definitions
- the invention relates to a slide rail for a door drive, in particular a door closer, with a, in particular C-shaped, slide rail profile for a slider of the door drive and at least one fastening piece which has a mounting section and a, in particular cuboid-shaped, pin projecting from the mounting section, the Pin can be inserted into an end face of the slide rail profile and the slide rail profile can be fastened via the mounting section at a mounting location, in particular a wall, a ceiling, a door frame or a door leaf.
- Slide rail profiles for door drives in particular door closers, in which a slider can be moved linearly and is connected to the door drive via an actuating lever, are generally known.
- slide rail profiles are provided with openings such as bores or elongated holes in the area of their front sides for attachment to a wall or ceiling, for example. After cutting to length, additional processing of the slide rail profile is therefore required.
- fastening pieces with prefabricated fastening holes which are inserted into the front of the slide rail profile and fixed there by means of a clamping screw or a set screw.
- the present application is based on the object of specifying a slide rail of the type mentioned at the beginning, which can be installed with as little effort as possible.
- a slide rail with the features of claim 1, and in particular in that at least one fixing element, which is designed separately from the slide rail profile and the fastening piece, is provided, which is held on the pin of the fastening piece and, together with the pin, into the end face of the slide rail profile , in particular a chamber of the slide rail profile, can be inserted, wherein when inserted into the end face of the slide rail profile, the fixing element automatically clamps the pin of the fastening piece in the slide rail profile in a force-fitting manner.
- at least one fixing element which is designed separately from the slide rail profile and the fastening piece, is provided, which is held on the pin of the fastening piece and, together with the pin, into the end face of the slide rail profile , in particular a chamber of the slide rail profile, can be inserted, wherein when inserted into the end face of the slide rail profile, the fixing element automatically clamps the pin of the fastening piece in the slide rail profile in a force-fitting manner.
- the fastening piece or the pin of the fastening piece only has to be inserted into the slide rail profile and is therefore automatically clamped in the slide rail profile, no additional screwing is required, unlike in the prior art. Accordingly, no tools are required to fix the fastening piece in the slide rail profile. The assembly effort can thereby be reduced and the comfort for the fitter when attaching the slide rail to the assembly site can be increased.
- the slide rail according to the invention thus enables a simple, tool-free pluggable fixation of the fastening piece in the slide rail profile. Due to the separate design of the fixing element, the fixing element can be made from a different material than the pin or the fastening piece or the slide rail profile. When producing the fixing element, no compromises due to the material of the other two components have to be made with regard to its desired shape and its desired properties.
- the fixing element can hold the pin of the fastening piece in the position of use of the slide rail in the vertical and/or horizontal direction in the slide rail profile jam. Whether the clamping takes place only in the vertical direction, only in the horizontal direction or in both directions depends on the specific design of the fixing element and its arrangement on the pin.
- the fixing element is designed as an elastically deformable insert or as an insert piece with at least one resilient clamping section. Due to the elastic properties of the insert or the insert piece, manufacturing tolerances can be easily compensated for. In addition, the choice of the value of the modulus of elasticity of the elastically deformable insert or the resilient clamping section can influence how much force should be required for inserting the fastening piece into the slide rail profile or how strong the fixation of the fastening piece should be in the slide rail profile.
- the elastically deformable insert can be designed as an O-ring, which is arranged in the inserted state of the fastening piece between the pin of the fastening piece and an inner wall of the slide rail profile, in particular consisting of an elastomer.
- O-rings are available cheaply.
- an O-ring enables the pin of the fastening piece to be clamped in the slide rail profile over the entire circumference of the pin, so that in a use position of the slide rail, clamping and manufacturing tolerance compensation can take place both in the vertical direction and in the horizontal direction.
- the O-ring is inserted into an annular groove formed on the pin of the fastening piece, which lies in a plane that runs transversely, in particular perpendicular, to the insertion direction of the fastening piece.
- the annular groove allows the O-ring to sit in a defined manner on the tenon of the fastening piece and thus ensure optimal clamping.
- the respective resilient clamping section of the fixing element is deflected from a rest position when the fastening piece is inserted and presses against an inner wall of the slide rail profile in order to clamp the pin of the fastening piece in the slide rail profile in a force-fitting manner.
- the fixing element can have one or more spring-elastic clamping sections designed in this way.
- the at least one resilient clamping section of the fixing element can be designed, for example, as a resilient arm, a resilient web and/or a curved flat spring.
- the at least one spring-elastic clamping section of the fixing element has at least one spring-elastic arm which can be deflected in the vertical direction in a position of use of the slide rail in order to clamp the pin in the vertical direction in the slide rail profile, and at least one in a position of use of the slide rail resilient arm that can be deflected in the horizontal direction in order to clamp the pin in the horizontal direction in the slide rail profile.
- the at least one spring-elastic clamping section of the fixing element has at least one spring-elastic arm which can be deflected in the vertical direction in a position of use of the slide rail in order to clamp the pin in the vertical direction in the slide rail profile, and at least one in a position of use of the slide rail resilient arm that can be deflected in the horizontal direction in order to clamp the pin in the horizontal direction in the slide rail profile.
- the at least one resilient arm that can be deflected in the horizontal direction comprises two resilient arms that are located on opposite lateral sides of the pin and can each be deflected in the horizontal direction. This symmetry allows the clamping and error tolerance compensation to be further optimized.
- the insert can be held on the pin of the fastening piece by means of a clip connection.
- a clip connection makes it easy to attach the insert to the tenon before the insert is assembled is inserted with the pin into the slide rail profile. Furthermore, this connection can be made quickly and intuitively.
- the at least one resilient arm that can be deflected in the vertical direction and/or the at least one resilient arm that can be deflected in the horizontal direction is designed as a snap hook, which is part of the clip connection.
- the two resilient arms that can be deflected in the horizontal direction are each designed as a snap hook.
- the respective deflectable spring-elastic arm thus fulfills a dual function.
- the pin of the fastening piece is securely clamped in the slide rail profile by the deflectable spring-elastic arm, and on the other hand, the fixing element is securely held on the pin of the fastening piece by the deflectable spring-elastic arm in order not to lose the fixing element when inserting the pin of the fastening piece into the slide rail profile .
- the insert is non-positively inserted into a receptacle formed in the pin of the fastening piece and protrudes outwards from the receptacle with the respective resilient clamping section, in particular a respective resilient web.
- the insert is held in a force-fitting manner on the pin of the fastening piece.
- the receptacle passes through the pin of the fastening piece in a direction transverse, in particular perpendicular, to the insertion direction, in particular in a use position of the slide rail in the lateral direction, and on each of the two, in particular lateral, sides of the pin through which the receptacle passes a resilient clamping section of the insert inserted into the receptacle protrudes outwards from the receptacle.
- a receptacle is formed on two opposite sides of the pin of the fastening piece, in particular on the lateral side in a position of use of the slide rail, with a fixing element being inserted into each of the receptacles, which moves out of the receptacle with the respective resilient clamping section protrudes outside. Manufacturing tolerances can be done in a horizontal direction.
- the insert piece in a position of use of the slide rail, is placed on the top of the pin of the fastening piece and the at least one resilient clamping section of the fixing element is designed as a curved flat spring in order to clamp the pin in the vertical direction in the slide rail profile. Manufacturing tolerances can be done in the vertical direction.
- This embodiment is particularly simple and therefore inexpensive to produce.
- the fixing element has a plug-in section which engages non-positively in a recess formed on the top of the pin in order to hold the fixing element on the pin of the fastening piece, or that the fixing element comprises two resilient clamping sections, each as a curved flat spring are formed, it being provided in particular that the two curved flat springs adjoin one another on the plug-in section. With two curved flat springs, the clamping force can be increased compared to one curved flat spring.
- the mounting section of the fastening piece has a continuous fastening opening, in particular a bore or an elongated hole, for a fastening means, in particular a screw, in order to fasten the fastening piece and thus the slide rail profile and the slide rail as a whole at the installation location.
- a fastening means in particular a screw
- two such fastening pieces will regularly be provided, which can be inserted into the two end faces of the slide rail profile in order to fasten the slide rail profile at the installation location.
- a slide rail 11 for a door drive in particular a door closer, is shown in a position of use of the slide rail 11.
- the slide rail 11 comprises a C-shaped slide rail profile 13, in which a slider (not shown) of the door drive can be moved linearly and is connected to the door drive in a generally known manner via an actuating lever.
- the slide rail 11 includes a fastening piece 15, via which the slide rail 11 can be attached to a wall or another mounting location.
- the fastening piece 15 has a mounting section 17 and a preferably cuboid-shaped pin 19 projecting from the mounting section 17. With the pin 19, the fastening piece 15 is inserted at the front into a chamber 21 of the slide rail profile 13 formed by the C-shaped slide rail profile 13.
- the mounting section 17 has a continuous elongated hole 23 through which a screw 29 or the like can be passed in order to fasten the fastening piece 15 at the mounting location.
- a separately designed fixing element 25 which serves to clamp the pin 19 inserted into the slide rail profile 13 in a force-fitting manner and thus to fix the fastening piece 15 on the slide rail profile 13.
- the fixing element 25 is designed as an elastically deformable insert in the form of an O-ring, which is slightly expanded and thus captively held in an annular groove 27 formed in the pin 19 of the fastening piece 15 and then inserted together with the pin 19 into the slide rail profile 13 to be plugged in.
- the annular groove 27 lies in a plane that runs perpendicular to the insertion direction of the pin 19 or the fastening piece 15.
- the O-ring 25 is then between the pin 19 of the fastening piece 15 and an inner wall of the slide rail profile 13 or the chamber 21 jammed, whereby the pin 19 is jammed in the slide rail profile 13. This is done automatically and without any tools when the pin 19 is inserted into the slide rail profile 13.
- the clamping acts both in the vertical direction and in the horizontal direction, as indicated by the corresponding arrows in Fig. 1 is indicated.
- Fig. 1a the slide rail 11 is shown in the assembled state, ie the pin 19 of the fastening piece 15 is inserted together with the O-ring 25 into the slide rail profile 13 and clamped there.
- Fig. 1b the fastening piece 15 and the O-ring 25 are shown in an exploded view, while in Fig. 1c the O-ring 25 is inserted into the annular groove 27 of the pin 19 of the fastening piece 15.
- a corresponding fastening piece and a corresponding fixing element are also provided, which are inserted analogously into the other end face of the slide rail profile 13.
- an insert with three resilient clamping sections is used as the fixing element 25 instead of an O-ring.
- the insert 25 comprises a centrally arranged resilient arm 31 that can be deflected in the vertical direction and two laterally arranged arms 33 that can each be deflected in the horizontal direction.
- the respective resilient arm 31, 33 is deflected from its rest position and presses against it the inner wall of the slide rail profile 13.
- the pin 19 can be positively clamped in the slide rail profile 13 in the vertical direction, and with the two spring-elastic arms 33 that can be deflected in the horizontal direction, the pin 19 can be clamped in the horizontal direction Direction can be clamped non-positively in the slide rail profile 13.
- the spring-elastic arm 31 of the insert 25, which can be deflected in the vertical direction, is also designed as a snap hook 35, which engages in a hook receptacle 37 formed on the pin 19 in the form of a window cutout.
- the spring-elastic arm 31, which can be deflected in the vertical direction, and the hook receptacle 37 form a clip connection in order to hold the insert piece 25 on the pin 19 of the fastening piece 15.
- FIG. 3 The exemplary embodiment shown shows a variant of the one in Fig. 2 shown embodiment, in which instead of the spring-elastic arm 31 that can be deflected in the vertical direction, the two arms 33 that can be deflected in the horizontal direction are each designed as snap hooks 35, which engage in non-visible hook receptacles formed on the pin 19.
- the exemplary embodiment according to Fig. 4 shows an insert 25, which is non-positively inserted into a receptacle 39 formed in the pin 19, which passes through the pin 19 in the lateral direction, and which has a spring-elastic web 41 on the two lateral sides of the pin 19, which is different from a spring-elastic one Arm is supported not only at one end but at both ends, protruding from the receptacle 39.
- the two resilient webs 41 allow the pin 19 to be positively clamped in the slide rail profile 13 in the horizontal direction.
- the non-positive connection of the insert 25 with the receptacle 39 of the pin 19 can be realized, for example, in that the part of the insert 25 received in the receptacle 39 has two elongated, each curved outwards, flexible web sections 43, which when inserted into the receptacle 39 jam.
- FIG. 5 The exemplary embodiment shown shows a variant of the one in Fig. 4 shown embodiment, in which instead of an insert piece inserted into a receptacle, two insert pieces 25 are provided, which are inserted into corresponding, Receptacles 39 formed in the two lateral sides of the pin 19 of the fastening piece 15 are inserted, with only one receptacle 39 being visible.

Um auf diese Bearbeitung verzichten zu können, ist es bekannt, Befestigungsstücke mit vorgefertigten Befestigungsbohrungen zu verwenden, die stirnseitig in das Gleitschienenprofil eingesteckt und dort mittels einer Klemmschraube oder einem Gewindestift fixiert werden. Allerdings ist hiermit ein gewisser zusätzlicher Aufwand bei der Montage verbunden.Slide rail profiles for door drives, in particular door closers, in which a slider can be moved linearly and is connected to the door drive via an actuating lever, are generally known. As standard, slide rail profiles are provided with openings such as bores or elongated holes in the area of their front sides for attachment to a wall or ceiling, for example. After cutting to length, additional processing of the slide rail profile is therefore required. In order to be able to dispense with this processing, it is known to use fastening pieces with prefabricated fastening holes, which are inserted into the front of the slide rail profile and fixed there by means of a clamping screw or a set screw. However, this involves a certain amount of additional effort during assembly.
Der vorliegenden Anmeldung liegt die Aufgabe zugrunde, eine Gleitschiene der eingangs genannten Art anzugeben, die mit möglichst geringem Aufwand montiert werden kann.The present application is based on the object of specifying a slide rail of the type mentioned at the beginning, which can be installed with as little effort as possible.
Diese Aufgabe wird durch eine Gleitschiene mit den Merkmalen des Anspruchs 1 gelöst, und insbesondere dadurch, dass wenigstens ein separat von dem Gleitschienenprofil und dem Befestigungsstück ausgebildetes Fixierelement vorgesehen ist, das an dem Zapfen des Befestigungsstücks gehalten und zusammen mit dem Zapfen in die Stirnseite des Gleitschienenprofils, insbesondere einer Kammer des Gleitschienenprofils, einsteckbar ist, wobei beim Einstecken in die Stirnseite des Gleitschienenprofils das Fixierelement den Zapfen des Befestigungsstücks automatisch kraftschlüssig in dem Gleitschienenprofil verklemmt.This object is achieved by a slide rail with the features of claim 1, and in particular in that at least one fixing element, which is designed separately from the slide rail profile and the fastening piece, is provided, which is held on the pin of the fastening piece and, together with the pin, into the end face of the slide rail profile , in particular a chamber of the slide rail profile, can be inserted, wherein when inserted into the end face of the slide rail profile, the fixing element automatically clamps the pin of the fastening piece in the slide rail profile in a force-fitting manner.
Da das Befestigungsstück bzw. der Zapfen des Befestigungsstücks lediglich in das Gleitschienenprofil eingesteckt werden muss und dadurch automatisch in dem Gleitschienenprofil verklemmt, ist, anders als im Stand der Technik, kein zusätzliches Schrauben erforderlich. Entsprechen ist kein Werkzeug zum Fixieren des Befestigungsstücks in dem Gleitschienenprofil erforderlich. Der Montageaufwand kann dadurch reduziert und der Komfort für den Monteur bei der Befestigung der Gleitschiene am Montageort erhöht werden. Die erfindungsgemäße Gleitschiene ermöglicht somit eine einfache, werkzeuglose steckbare Fixierung des Befestigungsstücks im Gleitschienenprofil. Durch die separate Ausbildung des Fixierelements kann das Fixierelement aus einem anderen Material hergestellt werden als der Zapfen bzw. das Befestigungsstück oder das Gleitschienenprofil. Bei der Herstellung des Fixierelements müssen hinsichtlich seiner gewünschten Form und seinen gewünschten Eigenschaften daher keine durch das Material der beiden anderen Bauteile bedingten Kompromisse eingegangen werden.Since the fastening piece or the pin of the fastening piece only has to be inserted into the slide rail profile and is therefore automatically clamped in the slide rail profile, no additional screwing is required, unlike in the prior art. Accordingly, no tools are required to fix the fastening piece in the slide rail profile. The assembly effort can thereby be reduced and the comfort for the fitter when attaching the slide rail to the assembly site can be increased. The slide rail according to the invention thus enables a simple, tool-free pluggable fixation of the fastening piece in the slide rail profile. Due to the separate design of the fixing element, the fixing element can be made from a different material than the pin or the fastening piece or the slide rail profile. When producing the fixing element, no compromises due to the material of the other two components have to be made with regard to its desired shape and its desired properties.
Vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen beschrieben.Advantageous embodiments of the invention are described in the dependent claims.
Das Fixierelement kann den Zapfen des Befestigungsstücks in der Verwendungsstellung der Gleitschiene in vertikaler und/oder horizontaler Richtung in dem Gleitschienenprofil verklemmen. Ob die Klemmung lediglich in vertikaler Richtung, lediglich in horizontaler Richtung oder in beiden Richtungen erfolgt, ist abhängig von der konkreten Ausgestaltung des Fixierelements und dessen Anordnung an dem Zapfen.The fixing element can hold the pin of the fastening piece in the position of use of the slide rail in the vertical and/or horizontal direction in the slide rail profile jam. Whether the clamping takes place only in the vertical direction, only in the horizontal direction or in both directions depends on the specific design of the fixing element and its arrangement on the pin.
Insbesondere ist das Fixierelement als ein elastisch deformierbarer Einsatz oder als ein Einsatzstück mit wenigstens einem federelastischen Klemmabschnitt ausgebildet. Aufgrund der elastischen Eigenschaften des Einsatzes bzw. des Einsatzstücks können auf einfache Weise Fertigungstoleranzen ausgeglichen werden. Darüber hinaus kann über die Wahl des Werts des Elastizitätsmoduls des elastisch deformierbaren Einsatzes bzw. des federelastischen Klemmabschnitts beeinflusst werden, wieviel Kraft für das Einstecken des Befestigungsstücks in das Gleitschienenprofil erforderlich sein soll bzw. wie stark die Fixierung des Befestigungsstücks in dem Gleitschienenprofil ausgebildet sein soll.In particular, the fixing element is designed as an elastically deformable insert or as an insert piece with at least one resilient clamping section. Due to the elastic properties of the insert or the insert piece, manufacturing tolerances can be easily compensated for. In addition, the choice of the value of the modulus of elasticity of the elastically deformable insert or the resilient clamping section can influence how much force should be required for inserting the fastening piece into the slide rail profile or how strong the fixation of the fastening piece should be in the slide rail profile.
Der elastisch deformierbare Einsatz kann als ein im eingesteckten Zustand des Befestigungsstücks zwischen dem Zapfen des Befestigungsstücks und einer Innenwand des Gleitschienenprofils angeordneter, insbesondere aus einem Elastomer bestehender, O-Ring ausgebildet sein. O-Ringe sind günstig erhältlich. Darüber hinaus ermöglicht ein O-Ring ein Verklemmen des Zapfens des Befestigungsstücks in dem Gleitschienenprofil über den gesamten Umfang des Zapfens hinweg, so dass in einer Verwendungsstellung der Gleitschiene eine Klemmung und ein Fertigungstoleranzausgleich sowohl in vertikaler Richtung als auch in horizontaler Richtung erfolgen kann.The elastically deformable insert can be designed as an O-ring, which is arranged in the inserted state of the fastening piece between the pin of the fastening piece and an inner wall of the slide rail profile, in particular consisting of an elastomer. O-rings are available cheaply. In addition, an O-ring enables the pin of the fastening piece to be clamped in the slide rail profile over the entire circumference of the pin, so that in a use position of the slide rail, clamping and manufacturing tolerance compensation can take place both in the vertical direction and in the horizontal direction.
Es kann vorgesehen sein, dass der O-Ring in eine an dem Zapfen des Befestigungsstücks ausgebildete Ringnut einsetzt ist, die in einer Ebene liegt, die quer, insbesondere senkrecht, zur Einsteckrichtung des Befestigungsstücks verläuft. Die Ringnut ermöglicht einen definierten Sitz des O-Rings auf dem Zapfen des Befestigungsstücks und damit eine optimale Klemmung.It can be provided that the O-ring is inserted into an annular groove formed on the pin of the fastening piece, which lies in a plane that runs transversely, in particular perpendicular, to the insertion direction of the fastening piece. The annular groove allows the O-ring to sit in a defined manner on the tenon of the fastening piece and thus ensure optimal clamping.
Insbesondere ist vorgesehen, dass der jeweilige federelastische Klemmabschnitt des Fixierelements im eingesteckten Zustand des Befestigungsstücks aus einer Ruheposition ausgelenkt ist und gegen eine Innenwand des Gleitschienenprofils drückt, um den Zapfen des Befestigungsstücks kraftschlüssig in dem Gleitschienenprofil zu verklemmen. Das Fixierelement kann einen oder mehrere derartig ausgebildete federelastische Klemmabschnitte aufweisen.In particular, it is provided that the respective resilient clamping section of the fixing element is deflected from a rest position when the fastening piece is inserted and presses against an inner wall of the slide rail profile in order to clamp the pin of the fastening piece in the slide rail profile in a force-fitting manner. The fixing element can have one or more spring-elastic clamping sections designed in this way.
Der wenigstens eine federelastische Klemmabschnitt des Fixierelements kann beispielsweise als ein federelastischer Arm, ein federelastischer Steg und/oder eine gewölbte Flachfeder ausgebildet sein.The at least one resilient clamping section of the fixing element can be designed, for example, as a resilient arm, a resilient web and/or a curved flat spring.
Gemäß einer Ausführungsform der Erfindung ist vorgesehen, dass der wenigstens eine federelastische Klemmabschnitt des Fixierelements wenigstens einen in einer Verwendungsstellung der Gleitschiene in vertikaler Richtung auslenkbaren federelastischen Arm, um den Zapfen in vertikaler Richtung in dem Gleitschienenprofil zu verklemmen, und wenigstens einen in einer Verwendungsstellung der Gleitschiene in horizontaler Richtung auslenkbaren federelastischen Arm, um den Zapfen in horizontaler Richtung in dem Gleitschienenprofil zu verklemmen, umfasst. Auch bei dieser Ausführungsform kann ein Ausgleich von Fertigungstoleranzen sowohl in vertikaler Richtung als auch in horizontaler Richtung ermöglicht werden. Bevorzugt ist vorgesehen, dass der wenigstens eine in horizontaler Richtung auslenkbare federelastische Arm zwei auf einander gegenüberliegenden lateralen Seiten des Zapfens liegende, jeweils in horizontaler Richtung auslenkbare federelastische Arme umfasst. Durch diese Symmetrie können die Klemmung und der Fehlertoleranzausgleich weiter optimiert werden.According to one embodiment of the invention, it is provided that the at least one spring-elastic clamping section of the fixing element has at least one spring-elastic arm which can be deflected in the vertical direction in a position of use of the slide rail in order to clamp the pin in the vertical direction in the slide rail profile, and at least one in a position of use of the slide rail resilient arm that can be deflected in the horizontal direction in order to clamp the pin in the horizontal direction in the slide rail profile. In this embodiment, too, it is possible to compensate for manufacturing tolerances both in the vertical direction and in the horizontal direction. It is preferably provided that the at least one resilient arm that can be deflected in the horizontal direction comprises two resilient arms that are located on opposite lateral sides of the pin and can each be deflected in the horizontal direction. This symmetry allows the clamping and error tolerance compensation to be further optimized.
Das Einsatzstück kann mittels einer Clipsverbindung an dem Zapfen des Befestigungsstücks gehalten sein. Eine Clipsverbindung ermöglicht es auf einfache Weise, das Einsatzstück an dem Zapfen anzubringen, bevor das Einsatzstück zusammen mit dem Zapfen in das Gleitschienenprofil eingesteckt wird. Darüber hinaus kann diese Verbindung schnell und intuitiv hergestellt werden.The insert can be held on the pin of the fastening piece by means of a clip connection. A clip connection makes it easy to attach the insert to the tenon before the insert is assembled is inserted with the pin into the slide rail profile. Furthermore, this connection can be made quickly and intuitively.
Bevorzugt ist der wenigstens eine in vertikaler Richtung auslenkbare federelastische Arm und/oder der wenigstens eine in horizontaler Richtung auslenkbare federelastische Arm als ein Schnapphaken ausgebildet ist, der Bestandteil der Clipsverbindung ist. Insbesondere sind die beiden in horizontaler Richtung auslenkbaren federelastischen Arme jeweils als ein Schnapphaken ausgebildet. Der jeweilige auslenkbare federelastische Arm erfüllt damit eine Doppelfunktion. Einerseits wird durch den auslenkbaren federelastischen Arm der Zapfen des Befestigungsstücks in dem Gleitschienenprofil sicher verklemmt, und andererseits wird durch den auslenkbaren federelastischen Arm das Fixierelement an dem Zapfen des Befestigungsstücks sicher gehalten, um das Fixierelement beim Einstecken des Zapfens des Befestigungsstücks in das Gleitschienenprofil nicht zu verlieren.Preferably, the at least one resilient arm that can be deflected in the vertical direction and/or the at least one resilient arm that can be deflected in the horizontal direction is designed as a snap hook, which is part of the clip connection. In particular, the two resilient arms that can be deflected in the horizontal direction are each designed as a snap hook. The respective deflectable spring-elastic arm thus fulfills a dual function. On the one hand, the pin of the fastening piece is securely clamped in the slide rail profile by the deflectable spring-elastic arm, and on the other hand, the fixing element is securely held on the pin of the fastening piece by the deflectable spring-elastic arm in order not to lose the fixing element when inserting the pin of the fastening piece into the slide rail profile .
Gemäß einer weiteren Ausführungsform der Erfindung ist das Einsatzstück in eine in dem Zapfen des Befestigungsstücks ausgebildete Aufnahme kraftschlüssig eingeschoben und steht mit dem jeweiligen federelastischen Klemmabschnitt, insbesondere einem jeweiligen federelastischen Steg, aus der Aufnahme nach außen hervor. Anstelle mittels eines Formschlusses wie bei einer Clipsverbindung wird bei dieser Ausführungsform das Einsatzstück kraftschlüssig an dem Zapfen des Befestigungsstücks gehalten.According to a further embodiment of the invention, the insert is non-positively inserted into a receptacle formed in the pin of the fastening piece and protrudes outwards from the receptacle with the respective resilient clamping section, in particular a respective resilient web. Instead of using a positive connection as with a clip connection, in this embodiment the insert is held in a force-fitting manner on the pin of the fastening piece.
Insbesondere kann vorgesehen sein, dass die Aufnahme den Zapfen des Befestigungsstücks in einer Richtung quer, insbesondere senkrecht, zur Einsteckrichtung, insbesondere in einer Verwendungsstellung der Gleitschiene in lateraler Richtung, durchsetzt und an jeder der beiden von der Aufnahme durchsetzten, insbesondere lateralen, Seiten des Zapfens ein federelastischer Klemmabschnitt des in die Aufnahme eingeschobenen Einsatzstücks aus der Aufnahme nach außen hervorsteht.In particular, it can be provided that the receptacle passes through the pin of the fastening piece in a direction transverse, in particular perpendicular, to the insertion direction, in particular in a use position of the slide rail in the lateral direction, and on each of the two, in particular lateral, sides of the pin through which the receptacle passes a resilient clamping section of the insert inserted into the receptacle protrudes outwards from the receptacle.
Alternativ kann vorgesehen sein, dass auf zwei einander gegenüberliegenden, insbesondere in einer Verwendungsstellung der Gleitschiene lateralen, Seiten des Zapfens des Befestigungsstücks jeweils eine Aufnahme ausgebildet ist, wobei in jede der Aufnahmen ein Fixierelement eingeschoben ist, das mit dem jeweiligen federelastischen Klemmabschnitt aus der Aufnahme nach außen hervorsteht. Ein Fertigungstoleranzen kann in horizontaler Richtung erfolgen.Alternatively, it can be provided that a receptacle is formed on two opposite sides of the pin of the fastening piece, in particular on the lateral side in a position of use of the slide rail, with a fixing element being inserted into each of the receptacles, which moves out of the receptacle with the respective resilient clamping section protrudes outside. Manufacturing tolerances can be done in a horizontal direction.
Gemäß einer weiteren Ausführungsform der Erfindung ist in einer Verwendungsstellung der Gleitschiene das Einsatzstück auf die Oberseite des Zapfens des Befestigungsstücks aufgesetzt und ist der wenigstens eine federelastische Klemmabschnitt des Fixierelements als eine gewölbte Flachfeder ausgebildet, um den Zapfen in vertikaler Richtung in dem Gleitschienenprofil zu verklemmen. Ein Fertigungstoleranzen kann in vertikaler Richtung erfolgen. Diese Ausführungsform ist besonders einfach und damit kostengünstig herstellbar.According to a further embodiment of the invention, in a position of use of the slide rail, the insert piece is placed on the top of the pin of the fastening piece and the at least one resilient clamping section of the fixing element is designed as a curved flat spring in order to clamp the pin in the vertical direction in the slide rail profile. Manufacturing tolerances can be done in the vertical direction. This embodiment is particularly simple and therefore inexpensive to produce.
Konkret kann vorgesehen sein, dass das Fixierelement einen Steckabschnitt aufweist, der kraftschlüssig in eine an der Oberseite des Zapfens ausgebildete Ausnehmung eingreift, um das Fixierelement an dem Zapfen des Befestigungsstücks zu halten, oder dass das Fixierelement zwei federelastische Klemmabschnitte umfasst, die jeweils als gewölbte Flachfeder ausgebildet sind, wobei insbesondere vorgesehen ist, dass die beiden gewölbten Flachfedern an dem Steckabschnitt aneinandergrenzen. Mit zwei gewölbten Flachfedern kann die Klemmkraft gegenüber einer gewölbten Flachfeder erhöht werden.Specifically, it can be provided that the fixing element has a plug-in section which engages non-positively in a recess formed on the top of the pin in order to hold the fixing element on the pin of the fastening piece, or that the fixing element comprises two resilient clamping sections, each as a curved flat spring are formed, it being provided in particular that the two curved flat springs adjoin one another on the plug-in section. With two curved flat springs, the clamping force can be increased compared to one curved flat spring.
Insbesondere weist der Montageabschnitt des Befestigungsstücks eine durchgehende Befestigungsöffnung, insbesondere eine Bohrung oder ein Langloch, für ein Befestigungsmittel, insbesondere eine Schraube, auf, um das Befestigungsstück und damit das Gleitschienenprofil und die Gleitschiene als Ganzes an dem Montageort zu befestigen.In particular, the mounting section of the fastening piece has a continuous fastening opening, in particular a bore or an elongated hole, for a fastening means, in particular a screw, in order to fasten the fastening piece and thus the slide rail profile and the slide rail as a whole at the installation location.
Darüber hinaus werden regelmäßig zwei derartige Befestigungstücke vorgesehen sein, die in die beiden Stirnseiten des Gleitschienenprofils einsteckbar sind, um das Gleitschienenprofil an dem Montageort zu befestigen.In addition, two such fastening pieces will regularly be provided, which can be inserted into the two end faces of the slide rail profile in order to fasten the slide rail profile at the installation location.
