Definitions

  • the invention relates to a guide rail for blinds.
  • Guide rails for blinds are usually attached to the reveal of a window or door opening and serve to guide the individual slats of blinds.
  • a guide pin is attached to the narrow end sides of the slats, which engages in the guide rail, the guide pin having a head part and a shaft which is narrower in relation to the head part.
  • the slats of the store can therefore be moved vertically up and down along the rails and remain fixed in the event of wind and weather.
  • the guide rails have a guide edge on both sides, against which the head part of the guide bolt of each lamella bears and is thus locked in the guide rail.
  • Such a guide rail with guide edges is, for example, in EP2535500 disclosed.
  • a guide pin is also shown, which is created in such a way that noises which can arise during the movement of the slats, in particular in the event of wind, are damped.
  • AT007694 shows a guide rail for blinds with an undercut longitudinal groove and in particular rubber-elastic profiles on the inside of the groove.
  • the head parts of the guide bolts, which engage in this rail, are locked by the rubber-elastic profiles.
  • the rubber-elastic profiles are used both for locking and for noise insulation.
  • AT501293 discloses a guide rail with a U-shaped mounting rail into which a further insert rail with an undercut guide groove is inserted by means of a resilient latching connection.
  • This guide rail enables the store to be dismantled by simply removing the insert rail and without removing the mounting rail from the reveal.
  • EP 2 669 462 discloses a holding device for a slat blind consisting of an L-shaped side guide rail and a flat side part which are rotatably connectable. To close the device, the side part is turned inwards towards the guide rail to form a groove-shaped rail and locked by means of a spring bar. In wind and weather, forces act on the slat in the direction of unlocking the rail.
  • DE 198 23 853 discloses a guide rail for slat blinds with a first, essentially L-shaped element, of which one leg of the L can be mounted on a reveal and has a joint bearing for receiving a second element which can be inserted lengthways.
  • the second element is rotatable in the spherical plain bearing, the second part being turned inwards towards the center of the first part in order to close the guide rail and fixed in the closed position by means of a flat spring or a detent.
  • GB 2466780 discloses a device for fixing the textile sides of a roller blind within a window frame consisting of two elongated parts which can be rotated relative to one another by means of a joint bearing.
  • the one, essentially L-shaped part can be fastened to the window frame, its leg, which can be fastened to the window frame, having an articulated bearing for receiving the second part.
  • the second part is turned inwards towards the first part, with rounded flexible surfaces made of thermoplastic rubber clamping the surfaces of the roller blind from the front and rear on the two parts.
  • the two parts of the device are fixed in the closed position by means of a latch.
  • the present invention has for its object to provide a guide rail for blinds, which facilitates assembly and whose materials withstand the weather elements.
  • a guide rail according to the invention for blinds has two rail parts, comprising a mounting rail as the base element and an insertion element, which can be movably connected to one another.
  • the base element essentially has a groove shape with a base surface, a first leg with an undercut and a second leg for receiving the insertion element.
  • the insertion element is essentially L-shaped and can be rotatably connected to the second leg of the base element. The insertion element can be pushed lengthways into the base element from its end and, in cooperation with the base element, can be rotated about its longitudinal axis between an open and a closed position.
  • the guide rail is characterized in that the insertion element, when it is pushed into the base element along its longitudinal axis, is rotatably but non-releasably connected to the base element by means of a rotatable connection at the free end of the second leg of the groove-shaped base element transversely to the longitudinal axis of the guide rail.
  • the insertion element can be rotated outward with respect to the base element, transversely to the longitudinal axis of the guide rail.
  • the insertion element can be rotated inwards into the groove-shaped base element transversely to the longitudinal axis of the guide rail.
  • an insertion element is first inserted into one end of a base element.
  • a base element with inserted insertion element is then attached to door or window reveals, the elongated base surface of the base element being connected to the reveal and the insertion element being freely rotatable in the base element.
  • the insert element is brought into its open position by rotating the insert element inwards with respect to the base element.
  • the slats are then inserted by placing their guide bolts in the longitudinal opening of the open guide rail.
  • the insert element is rotated by rotating it outward with respect to the base element and locked in the closed position with the base element.
  • the insertion element forms a second undercut on the groove-shaped base element of the guide rail, so that the head part of each guide pin is locked on the two undercuts.
  • the guide bolts with a head part and a comparatively narrower shaft can thus be moved along the rail, but are held in the closed rail by the narrow longitudinal opening.
  • one of the two rail parts of the guide rail has a rounded edge running along its length, the second of the two rail parts having a curved edge running along its length with a rounded inner profile.
  • the rounded edge is encompassed by the curved edge with a rounded inner profile, so that it is rotatably mounted.
  • the two rounded shapes, the round edge and the curved edge form the parts of the rotatable, non-detachable connection between the base and insert element.
  • the rotatability is thus ensured by a kind of longitudinal joint.
  • the nested rail parts form a double-walled and therefore very robust structure that can withstand wind forces at the location of the nested, rounded forms of the rotatable, non-detachable connection.
  • the rounded edge is arranged on the base element, while the curved edge runs along the length of the insertion element.
  • the rounded edge is arranged on the insert element, and the curved edge runs along the length of the base element.
  • the guide rail has a releasable locking between the base element and the insert element. This enables simple assembly and disassembly to remove the slats without having to remove the base element.
  • the locking is released by turning the insert element inwards into the groove-shaped base element.
  • the rail is relocked by turning the insert element outwards and engaging the lock.
  • the locking is implemented by a snap lock. This enables simple and quick locking of the two elements during assembly, which does not require any tools. Unlocking can be carried out either by hand or using a suitable tool.
  • the insert element has a knob or nose running along its length, the base element having a shoulder, a recess or a rib which locks the knob or nose of the insert element in its closed position.
  • the invention provides the particular advantage that the guide rail can only be unlocked and opened into the base element by rotating the insertion element inwards. Forces that act on the slat bolts in wind and weather so that the bolts are pulled away from the base element act in the direction of the closing and not the opening of the rail. If forces act on the lamella bolts due to wind and away from the base element, the rotatable connection is strengthened even more.
  • a strong wind can therefore not lead to an unintentional opening of the guide rail.
  • the invention provides the advantage of facilitating the assembly of blinds by first only mounting the guide rails themselves with base and inserted insert elements but without slats on the reveal, only then can the slats be used with guide bolts and finally the guide rails by simply turning and pressing closed and locked to the outside.
  • the assembly of blinds with the guide rail according to the invention is therefore simpler and less cumbersome in comparison to the previously known guide rails, because there the guide rails must be installed together with the guide bolts of the blinds that have already been inserted. Also across from the rail AT501293 the guide rail according to the invention has at least the advantage that it can be dismantled more easily.
  • Another embodiment of the guide rail according to the invention has one of the two rail parts of the guide rail a projection which extends over its length and extends to the other of the two rail parts of the guide rail when the two rail parts are pushed into one another.
  • a projection serves to further limit the freedom of movement between the two rail parts and to prevent unwanted lateral detachment of the insert element from the base element during rotation of the insert element.
  • the projection can either be arranged on the inside of the L-shape of the insert element or on the outside of the second leg of the base element.
  • the entire guide rail that is to say both the base element and the insert element, is made of the same material, for example aluminum.
  • the use of aluminum or other material for both rail parts leads to increased weather resistance of the guide rail. Due to the rotatability and the possibility of locking the insert element with the base element, no stretchable material such as plastic need be used for the insert element, which tires with heat and cold.
  • the aluminum is resistant in all weather and temperatures and does not tire in particular due to cold and heat.
  • a plastic insert loses its strength over time and in cold and heat, becomes soft or brittle and, after a certain period of time, the guide bolts can be unintentionally released from the rail.
  • the guide rail according to the invention in that its longitudinal opening with its two undercuts is made of aluminum or other metal and maintains its shape, size and strength in all weather situations and for a long time. This eliminates the risk of material fatigue and a reduction in locking. The service life of the guide rail is therefore extended.
  • the two elements of the guide rail are made of another suitable metal or a plastic instead of aluminum, provided that the plastic is UV-resistant and dimensionally stable.
  • the guide rail has not only two rail parts but three rail parts as a variant, namely a base element and two insertion elements, both insertion elements being rotatably and movably connectable to the base element.
  • the base element is again essentially groove-shaped, but also symmetrical with two mirror-symmetrical legs, which are each implemented to accommodate an insert element.
  • Both insertion elements are essentially L-shaped, and both Legs of the insert element have parts of a swivel joint which, in cooperation with the insert elements and the base element, allow the insert elements to rotate from an open to a closed position. Again, the slide-in elements can be locked with the base element. In the closed position of the two insertion elements, both insertion elements form an undercut on both sides along the longitudinal opening of the guide rail.
  • piping made of rubber or plastic can be used along the longitudinal opening to reduce noise.
  • the plastic or rubber has only this one function and has no influence on the function of locking the guide bolts in the rail.
  • the guide rail according to the invention is primarily suitable for slat blinds. Use for other blinds, such as vertical blinds or awnings, is also conceivable.
  • Figure 1a shows a short section of a guide rail 1 according to the invention and an associated blind slat 2.
  • the slat 2 has at its narrow ends a guide pin with a shaft 3 and a head part 4, which can be inserted into the guide rail 1 and locked there. (In the figures, only the guide pin and the guide rail are shown at one of the narrow ends.)
  • the guide rail is in Figure 1a shown in an open position in which the longitudinal opening L is wide enough to allow the head part 4 of the guide bolt to pass.

Description

Technisches GebietTechnical field

Die Erfindung betrifft eine FĂĽhrungsschiene fĂĽr Storen.The invention relates to a guide rail for blinds.

Stand der TechnikState of the art

Führungsschienen für Storen werden in der Regel an den Leibungen einer Fenster- oder Türöffnung befestigt und dienen der Führung der einzelnen Lamellen von Storen. Hierzu ist an den schmalen Endseiten der Lamellen jeweils ein Führungsbolzen befestigt, der in die Führungsschiene eingreift, wobei der Führungsbolzen einen Kopfteil und einen im Verhältnis zum Kopfteil schmaleren Schaft aufweist. Die Lamellen der Store können somit entlang den Schienen regelmässig senkrecht auf und ab bewegt werden und bleiben im Fall von Wind und Wetter fixiert. Die Führungsschienen weisen entlang ihrer Längsöffnung beidseitig eine Führungskante auf, an der sich der Kopfteil des Führungsbolzens jeder Lamelle anlegt und somit in der Führungsschiene arretiert wird.Guide rails for blinds are usually attached to the reveal of a window or door opening and serve to guide the individual slats of blinds. For this purpose, a guide pin is attached to the narrow end sides of the slats, which engages in the guide rail, the guide pin having a head part and a shaft which is narrower in relation to the head part. The slats of the store can therefore be moved vertically up and down along the rails and remain fixed in the event of wind and weather. Along their longitudinal opening, the guide rails have a guide edge on both sides, against which the head part of the guide bolt of each lamella bears and is thus locked in the guide rail.

Eine solche Führungsschiene mit Führungskanten ist beispielsweise in EP2535500 offenbart. Es ist zudem ein Führungsbolzen gezeigt, der so geschaffen ist, dass Geräusche, die bei der Bewegung der Lamellen insbesondere im Fall von Wind entstehen können, gedämpft werden.Such a guide rail with guide edges is, for example, in EP2535500 disclosed. A guide pin is also shown, which is created in such a way that noises which can arise during the movement of the slats, in particular in the event of wind, are damped.

AT007694 zeigt eine Führungsschiene für Storen mit einer hinterschnittenen Längsnut und insbesondere gummielastischen Profilen an den Innenseiten der Nut. Die Kopfteile der Führungsbolzen, die in diese Schiene eingreifen, werden von den gummielastischen Profilen arretiert. Die gummielastischen Profile dienen sowohl der Arretierung als auch der Lärmdämmung. AT007694 shows a guide rail for blinds with an undercut longitudinal groove and in particular rubber-elastic profiles on the inside of the groove. The head parts of the guide bolts, which engage in this rail, are locked by the rubber-elastic profiles. The rubber-elastic profiles are used both for locking and for noise insulation.

AT501293 offenbart eine Führungsschiene mit einer U-förmigen Halterungsschiene, in die eine weitere Einsatzschiene mit einer hinterschnittenen Führungsnut mittels einer federnden Rastverbindung eingesetzt wird. Diese Führungsschiene ermöglicht eine Demontage der Store durch Lösung von lediglich der Einsatzschiene und ohne Entfernung der Halterungsschiene von den Leibungen. AT501293 discloses a guide rail with a U-shaped mounting rail into which a further insert rail with an undercut guide groove is inserted by means of a resilient latching connection. This guide rail enables the store to be dismantled by simply removing the insert rail and without removing the mounting rail from the reveal.

EP 2 669 462 offenbart eine Haltevorrichtung für eine Lamellenstore bestehend aus einer L-förmigen Seitenführungsschiene und einem flächigen Seitenteil, die drehbar verbindbar sind. Zur Schliessung der Vorrichtung wird das Seitenteil zur Führungsschiene hin nach innen gedreht, um eine nutförmige Schiene zu bilden und mittels einer Federleiste verriegelt. Bei Wind und Wetter wirken Kräfte auf der Lamelle in Richtung der Entriegelung der Schiene. EP 2 669 462 discloses a holding device for a slat blind consisting of an L-shaped side guide rail and a flat side part which are rotatably connectable. To close the device, the side part is turned inwards towards the guide rail to form a groove-shaped rail and locked by means of a spring bar. In wind and weather, forces act on the slat in the direction of unlocking the rail.

DE 198 23 853 offenbart eine Führungsschiene für Lamellenstoren mit einem ersten, im Wesentlichen L-förmigen Element, wovon der eine Schenkel des L's auf einer Leibung montierbar ist und ein Gelenklager zur Aufnahme eines längs einschiebbaren zweiten Elements aufweist. Das zweite Element ist in dem Gelenklager drehbar, wobei zum Schliessen der Führungsschiene das zweite Teil nach innen zur Mitte des ersten Teils gedreht wird und mittels einer Flachfeder oder einer Rastnase in der geschlossenen Stellung fixiert wird. DE 198 23 853 discloses a guide rail for slat blinds with a first, essentially L-shaped element, of which one leg of the L can be mounted on a reveal and has a joint bearing for receiving a second element which can be inserted lengthways. The second element is rotatable in the spherical plain bearing, the second part being turned inwards towards the center of the first part in order to close the guide rail and fixed in the closed position by means of a flat spring or a detent.

GB 2466780 offenbart eine Vorrichtung zur Fixierung der textilen Seiten eines Rollos innerhalb eines Fensterrahmens bestehend aus zwei länglichen, mittels eines Gelenklagers zueinander drehbaren Teilen. Dabei ist das eine, im Wesentlichen L-förmige Teil am Fensterrahmen befestigbar, wobei dessen am Fensterrahmen befestigbare Schenkel ein Gelenklager zur Aufnahme des zweiten Teils aufweist. Zur Fixierung der textilen Flächen des ausgerollten Rollos wird der zweite Teil zum ersten Teil hin nach innen gedreht, wobei gerundete flexible Flächen aus thermoplastischem Gummi an den beiden Teilen die Flächen des Rollos von vorn und hinten klemmen. Die beiden Teile der Vorrichtung werden mittels einer Rastnase in der geschlossenen Stellung fixiert. GB 2466780 discloses a device for fixing the textile sides of a roller blind within a window frame consisting of two elongated parts which can be rotated relative to one another by means of a joint bearing. The one, essentially L-shaped part can be fastened to the window frame, its leg, which can be fastened to the window frame, having an articulated bearing for receiving the second part. To fix the textile surfaces of the rolled-out roller blind, the second part is turned inwards towards the first part, with rounded flexible surfaces made of thermoplastic rubber clamping the surfaces of the roller blind from the front and rear on the two parts. The two parts of the device are fixed in the closed position by means of a latch.

Weitere bekannte FĂĽhrungsschienen fĂĽr Storen weisen Einsatzschienen mit hinterschnittener FĂĽhrungsnut auf, die aus Kunststoff gefertigt sind. Diese Einsatzschienen werden von Hand in die Halterungsschiene eingepresst.Other known guide rails for blinds have insert rails with an undercut guide groove, which are made of plastic. These insert rails are pressed into the mounting rail by hand.

Zur Montage von Storen mit solchen Führungsschienen werden zunächst sämtliche Kopfteile der Führungsbolzen jeweils von einem Ende einer Schiene her in diese eingeschoben und sodann die Store mitsamt der Führungsschienen in die Fenster- oder Türöffnung gehoben und dort an den Leibungen montiert.To assemble blinds with such guide rails, first all head parts of the guide bolts are inserted into one end of a rail and then the store together with the guide rails is lifted into the window or door opening and mounted there on the reveal.

Der vorliegenden Erfindung ist die Aufgabe gestellt, eine Führungsschiene für Storen zu schaffen, die eine erleichterte Montage ermöglicht und dessen Materialien den Wetterelementen standhalten.The present invention has for its object to provide a guide rail for blinds, which facilitates assembly and whose materials withstand the weather elements.

Eine erfindungsgemässe Führungsschiene für Storen weist zwei Schienenteile auf, umfassend eine Halterungsschiene als Basiselement und ein Einschubelement, die beweglich miteinander verbindbar sind. Das Basiselement weist im Wesentlichen eine Nutform mit einer Basisfläche, einem ersten Schenkel mit einer Hinterschneidung und einem zweiten Schenkel zur Aufnahme des Einschubelements auf. Das Einschubelement ist im Wesentlichen L-förmig und lässt sich mit dem zweiten Schenkel des Basiselements drehbar verbinden. Das Einschubelement lässt sich in das Basiselement von dessen Ende her der Länge nach einschieben und ist in Zusammenwirkung mit dem Basiselement um dessen Längsachse zwischen einer offenen und einer geschlossenen Position drehbar. Zwischen dem Einschubelement und dem Basiselement besteht eine Längsöffnung, die in der offenen Position breiter ist als in der geschlossenen Position, wobei das Einschubelement in der geschlossenen Position an der Längsöffnung des nutförmigen Basiselements eine zweite Hinterschneidung bildet. Zudem ist das Einschubelement in der geschlossenen Position mit dem Basiselement verriegelbar. Die Führungsschiene zeichnet sich dadurch aus, dass das Einschubelement, wenn es entlang seiner Längsachse in das Basiselement eingeschoben ist, mittels einer drehbaren Verbindung am freien Ende des zweiten Schenkels des nutförmigen Basiselements quer zur Längsachse der Führungsschiene drehbar jedoch unlösbar mit dem Basiselement verbunden ist. Zum Schliessen der Führungsschiene in die geschlossene Position ist das Einschubelement bezüglich des Basiselements entsprechend quer zur Längsachse der Führungsschiene nach aussen drehbar. Zum Öffnen der Führungsschiene in die offene Position ist das Einschubelement entsprechend quer zur Längsachse der Führungsschiene in das nutförmige Basiselement hinein nach innen drehbar.A guide rail according to the invention for blinds has two rail parts, comprising a mounting rail as the base element and an insertion element, which can be movably connected to one another. The base element essentially has a groove shape with a base surface, a first leg with an undercut and a second leg for receiving the insertion element. The insertion element is essentially L-shaped and can be rotatably connected to the second leg of the base element. The insertion element can be pushed lengthways into the base element from its end and, in cooperation with the base element, can be rotated about its longitudinal axis between an open and a closed position. Between the insert element and the base element there is a longitudinal opening which is wider in the open position than in the closed position, the insert element in the closed position on the Longitudinal opening of the groove-shaped base element forms a second undercut. In addition, the insert element can be locked in the closed position with the base element. The guide rail is characterized in that the insertion element, when it is pushed into the base element along its longitudinal axis, is rotatably but non-releasably connected to the base element by means of a rotatable connection at the free end of the second leg of the groove-shaped base element transversely to the longitudinal axis of the guide rail. To close the guide rail in the closed position, the insertion element can be rotated outward with respect to the base element, transversely to the longitudinal axis of the guide rail. To open the guide rail into the open position, the insertion element can be rotated inwards into the groove-shaped base element transversely to the longitudinal axis of the guide rail.

Bei der Montage von Storen mit der erfindungsgemässen Führungsschiene wird zunächst ein Einschubelement vom einen Ende eines Basiselements in diese eingeschoben. Ein Basiselement mit eingeschobenen Einschubelement wird sodann jeweils an Tür- oder Fensterleibungen befestigt, wobei die längliche Basisfläche des Basiselements mit den Leibungen verbunden wird und das Einschubelement jeweils im Basiselement frei drehbar ist. Nachdem die Führungsschiene fest montiert worden ist, wird das Einschubelement in ihre offene Position gebracht, indem das Einschubelement bezüglich dem Basiselement nach innen gedreht wird. Darauf werden die Lamellen eingeführt, indem ihre Führungsbolzen in die Längsöffnung der offenen Führungsschiene platziert werden. Schliesslich wird das Einschubelement gedreht, indem es bezüglich dem Basiselement nach aussen gedreht wird, und in der geschlossenen Position mit dem Basiselement verriegelt. In dieser Position bildet das Einschubelement jeweils eine zweite Hinterschneidung am nutförmigen Basiselement der Führungsschiene, sodass der Kopfteil jedes Führungsbolzens an den beiden Hinterschneidungen arretiert ist. Die Führungsbolzen mit einem Kopfteil und einem im Vergleich schmaleren Schaft lassen sich so entlang der Schiene bewegen, werden jedoch durch die schmale Längsöffnung der geschlossenen Schiene in dieser gehalten.When assembling blinds with the guide rail according to the invention, an insertion element is first inserted into one end of a base element. A base element with inserted insertion element is then attached to door or window reveals, the elongated base surface of the base element being connected to the reveal and the insertion element being freely rotatable in the base element. After the guide rail has been firmly mounted, the insert element is brought into its open position by rotating the insert element inwards with respect to the base element. The slats are then inserted by placing their guide bolts in the longitudinal opening of the open guide rail. Finally, the insert element is rotated by rotating it outward with respect to the base element and locked in the closed position with the base element. In this position, the insertion element forms a second undercut on the groove-shaped base element of the guide rail, so that the head part of each guide pin is locked on the two undercuts. The guide bolts with a head part and a comparatively narrower shaft can thus be moved along the rail, but are held in the closed rail by the narrow longitudinal opening.

In einer Ausführung der Erfindung weist eines der zwei Schienenteile der Führungsschiene eine entlang seiner Länge verlaufenden gerundete Kante auf, wobei das zweite der zwei Schienenteile eine entlang seiner Länge verlaufende gewölbte Kante mit einem gerundetem Innenprofil aufweist. In der Zusammenwirkung der beiden Schienenteile wird die gerundete Kante von der gewölbten Kante mit gerundetem Innenprofil umfasst, sodass diese drehbar gelagert ist.In one embodiment of the invention, one of the two rail parts of the guide rail has a rounded edge running along its length, the second of the two rail parts having a curved edge running along its length with a rounded inner profile. In the interaction of the two rail parts, the rounded edge is encompassed by the curved edge with a rounded inner profile, so that it is rotatably mounted.

Die beiden gerundeten Formen, die runde Kante und die gewölbte Kante bilden die Teile der drehbaren, unlösbaren Verbindung zwischen Basis- und Einschubelement. Die Drehbarkeit ist somit durch eine Art Längsgelenk gewährleistet. Die ineinander geschobenen Schienenteile bilden an der Stelle der ineinander geschobenen, gerundeten Formen der drehbaren, unlösbaren Verbindung eine doppelwandige und somit sehr robuste Struktur, die Windkräften widerstehen kann.The two rounded shapes, the round edge and the curved edge form the parts of the rotatable, non-detachable connection between the base and insert element. The rotatability is thus ensured by a kind of longitudinal joint. The nested rail parts form a double-walled and therefore very robust structure that can withstand wind forces at the location of the nested, rounded forms of the rotatable, non-detachable connection.

In einer ersten Variante ist die gerundete Kante am Basiselement angeordnet während die gewölbte Kante entlang der Länge des Einschubelements verläuft. In einer zweiten Variante ist die gerundete Kante am Einschubelement angeordnet, und die gewölbte Kante verläuft entlang der Länge des Basiselements.In a first variant, the rounded edge is arranged on the base element, while the curved edge runs along the length of the insertion element. In a second variant, the rounded edge is arranged on the insert element, and the curved edge runs along the length of the base element.

In einer Ausführung der Erfindung weist die Führungsschiene eine lösbare Verriegelung zwischen Basis- und Einschubelement auf. Dies ermöglicht eine einfache Montage sowie Demontage zur Entfernung der Lamellen ohne dass das Basiselement entfernt werden muss. Die Verriegelung wird dabei gelöst, indem das Einschubelement nach innen in das nutförmige Basiselement hinein gedreht wird. Eine Wiederverriegelung der Schiene geschieht durch Drehung des Einschubelements nach aussen und Einrasten der Verriegelung.In one embodiment of the invention, the guide rail has a releasable locking between the base element and the insert element. This enables simple assembly and disassembly to remove the slats without having to remove the base element. The locking is released by turning the insert element inwards into the groove-shaped base element. The rail is relocked by turning the insert element outwards and engaging the lock.

In einer Ausführung ist die Verriegelung durch einen Schnappverschluss realisiert. Diese ermöglicht eine einfache und schnell ausgeführte Verriegelung der beiden Elemente während der Montage, die keine Werkzeuge erfordert. Die Entriegelung kann entweder von Hand oder durch ein geeignetes Werkzeug ausgeführt werden.In one version, the locking is implemented by a snap lock. This enables simple and quick locking of the two elements during assembly, which does not require any tools. Unlocking can be carried out either by hand or using a suitable tool.

In einer besonderen Ausführung der Erfindung weist das Einschubelement eine entlang seiner Länge verlaufende Noppe oder Nase auf, wobei das Basiselement einen Absatz, eine Ausnehmung oder eine Rippe aufweist, welche die Noppe oder Nase des Einschubelements in seiner geschlossenen Position arretiert.
Nach Einführung der Führungsbolzen von Storenlamellen in die Schiene in offener Position und darauffolgende Drehung des Einschubelements in seine geschlossene Position ermöglicht die Verriegelung eine Fixierung des Einschubelements am Basiselement. Die Kopfteile der Führungsbolzen lassen sich in der Schiene auf und ab bewegen aber nicht mehr aus ihr herausziehen, indem einerseits die Führungsbolzen durch die beidseitige Hinterschneidung an der Längsöffnung der zusammengesetzten Führungsschiene arretiert sind und anderseits das Einschubelement fixiert ist und die Führungsschiene in seiner geschlossenen Position sich nicht ohne Krafteinwirkung durch einen Monteur öffnen lässt. Zudem erbringt die Erfindung den besonderen Vorteil, dass die Führungsschiene nur durch Drehung des Einschubelements nach innen in das Basiselement hinein entriegelt und geöffnet werden kann. Kräfte, die bei Wind und Wetter auf die Lamellenbolzen wirken, sodass die Bolzen vom Basiselement weg gezogen werden, wirken dabei in der Richtung der Schliessung und nicht der Öffnung der Schiene. Wirken Kräfte aufgrund von Wind auf die Lamellenbolzen und weg vom Basiselement so verstärkt sich die drehbare Verbindung umso mehr.In a special embodiment of the invention, the insert element has a knob or nose running along its length, the base element having a shoulder, a recess or a rib which locks the knob or nose of the insert element in its closed position.
After insertion of the guide bolts of blind slats into the rail in the open position and subsequent rotation of the insert element into its closed position, the locking enables the insert element to be fixed to the base element. The head parts of the guide bolts can be moved up and down in the rail, but can no longer be pulled out of them, on the one hand the guide bolts are locked by the undercut on both sides at the longitudinal opening of the assembled guide rail and on the other hand the insertion element is fixed and the guide rail is in its closed position cannot be opened by a technician without the application of force. In addition, the invention provides the particular advantage that the guide rail can only be unlocked and opened into the base element by rotating the insertion element inwards. Forces that act on the slat bolts in wind and weather so that the bolts are pulled away from the base element act in the direction of the closing and not the opening of the rail. If forces act on the lamella bolts due to wind and away from the base element, the rotatable connection is strengthened even more.

Ein starker Wind kann deshalb nicht zu einem ungewollten Ă–ffnen der FĂĽhrungsschiene fĂĽhren.A strong wind can therefore not lead to an unintentional opening of the guide rail.

Die Erfindung erbringt den Vorteil einer erleichterte Montage von Storen, indem zuerst nur die Führungsschienen selbst mit Basis- und eingeschobenem Einschubelementen aber ohne Lamellen an den Leibungen montiert werden, erst danach die Lamellen mit Führungsbolzen eingesetzt werden können und schliesslich die Führungsschienen durch einfaches Drehen und Drücken nach aussen geschlossen und verriegelt werden. Die Montage von Storen mit der erfindungsgemässen Führungsschiene ist dadurch im Vergleich zu den bislang bekannten Führungsschienen einfacher und weniger umständlich, denn dort müssen die Führungsschienen gleichzeitig zusammen mit den bereits eingeführten Führungsbolzen der Storen montiert werden. Auch gegenüber der Schiene aus AT501293 hat die erfindungsgemässe Führungsschiene zumindest den Vorteil, dass sie einfacher demontiert werden kann.The invention provides the advantage of facilitating the assembly of blinds by first only mounting the guide rails themselves with base and inserted insert elements but without slats on the reveal, only then can the slats be used with guide bolts and finally the guide rails by simply turning and pressing closed and locked to the outside. The assembly of blinds with the guide rail according to the invention is therefore simpler and less cumbersome in comparison to the previously known guide rails, because there the guide rails must be installed together with the guide bolts of the blinds that have already been inserted. Also across from the rail AT501293 the guide rail according to the invention has at least the advantage that it can be dismantled more easily.

Eine weitere Ausführung der erfindungsgemässen Führungsschiene weist eines der beiden Schienenteile der Führungsschiene einen Vorsprung auf, der sich über seine Länge erstreckt und zum anderen der zwei Schienenteile der Führungsschiene hin erstreckt, wenn die beiden Schienenteile ineinander geschoben sind. Ein solcher Vorsprung dient dazu, den freien Bewegungsspielraum zwischen den beiden Schienenteile weiter zu begrenzen und ein ungewolltes seitliches Lösen des Einschubelements aus dem Basiselement während einer Drehung des Einschubelements vermehrt zu verhindern. Dies hat insbesondere den Vorteil, dass das Einschubelement bei der Montage an einer Leibung und vor dessen Verriegelung sich nicht aus dem Basiselement löst. So besteht auch kein Risiko, dass das Einschubelement herunterfällt und Schäden anrichten oder jemanden verletzen kann.Another embodiment of the guide rail according to the invention has one of the two rail parts of the guide rail a projection which extends over its length and extends to the other of the two rail parts of the guide rail when the two rail parts are pushed into one another. Such a projection serves to further limit the freedom of movement between the two rail parts and to prevent unwanted lateral detachment of the insert element from the base element during rotation of the insert element. This has the particular advantage that the insertion element does not come loose from the base element when it is mounted on a reveal and before it is locked. There is also no risk that the insert element will fall and cause damage or injure someone.

Der Vorsprung kann entweder an der Innenseite der L-Form des Einschubelements oder an der Aussenseite des zweiten Schenkels des Basiselements angeordnet sein.The projection can either be arranged on the inside of the L-shape of the insert element or on the outside of the second leg of the base element.

In einer Ausführung ist die gesamte Führungsschiene, das heisst sowohl Basisals auch Einschubelement, aus dem gleichen Material, beispielsweise Aluminium, gefertigt. Der Einsatz von Aluminium oder anderem Material für beide Schienenteile führt zu einer vergrösserten Wetterbeständigkeit der Führungsschiene. Aufgrund der Drehbarkeit und Möglichkeit das Einschubelement mit dem Basiselement zu verriegeln braucht kein dehnbares Material wie Kunststoff für das Einschubelement zum Einsatz zu kommen, das bei Hitze und Kälte ermüdet. Das Aluminium ist in allen Wettern und Temperaturen beständig und ermüdet insbesondere nicht aufgrund von Kälte und Hitze. Ein Einsatzteil aus Kunststoff hingegen verliert über die Zeit und in Kälte und Hitze seine Festigkeit, wird weich oder spröde und lässt die Führungsbolzen sich nach gewisser Zeit ungewollt aus der Schiene lösen. An der Führungsschiene gemäss der Erfindung wird dies jedoch vermieden, indem ihre Längsöffnung mit ihren beiden Hinterschneidungen aus Aluminium oder anderem Metall sind und in allen Wettersituationen und über lange Zeit ihre Form, Grösse und Festigkeit beibehalten. Dies eliminiert das Risiko einer Materialermüdung und einer Verminderung der Arretierung. Die Einsatzdauer der Führungsschiene ist somit verlängert.In one embodiment, the entire guide rail, that is to say both the base element and the insert element, is made of the same material, for example aluminum. The use of aluminum or other material for both rail parts leads to increased weather resistance of the guide rail. Due to the rotatability and the possibility of locking the insert element with the base element, no stretchable material such as plastic need be used for the insert element, which tires with heat and cold. The aluminum is resistant in all weather and temperatures and does not tire in particular due to cold and heat. A plastic insert, on the other hand, loses its strength over time and in cold and heat, becomes soft or brittle and, after a certain period of time, the guide bolts can be unintentionally released from the rail. However, this is avoided on the guide rail according to the invention in that its longitudinal opening with its two undercuts is made of aluminum or other metal and maintains its shape, size and strength in all weather situations and for a long time. This eliminates the risk of material fatigue and a reduction in locking. The service life of the guide rail is therefore extended.

In einer weiteren Ausführung der Erfindung sind die beiden Elemente der Führungsschiene anstelle aus Aluminium aus einem anderen geeigneten Metall oder einem Kunststoff gefertigt, vorausgesetzt der Kunststoff ist UV-beständig und formstabil.In a further embodiment of the invention, the two elements of the guide rail are made of another suitable metal or a plastic instead of aluminum, provided that the plastic is UV-resistant and dimensionally stable.

In einer weiteren Ausführung der Erfindung weist die Führungsschiene als Variante nicht nur zwei Schienenteile sondern drei Schienenteile auf, nämlich ein Basiselement und zwei Einschubelemente, wobei beide Einschubelemente drehbar und beweglich mit dem Basiselement verbindbar sind. Das Basiselement ist wiederum im Wesentlichen Nut-förmig, jedoch auch symmetrisch mit zwei spiegelsymmetrischen Schenkeln, die je zur Aufnahme eines Einschubelements realisiert sind. Beide Einschubelemente sind im Wesentlichen L-förmig, und beide Schenkel des Einschubelements weisen Teile eines Drehgelenks auf, die in Zusammenwirkung der Einschubelemente mit dem Basiselement eine Drehung der Einschubelemente von einer offenen in eine geschlossene Position gewähren. Wiederum sind die Einschubelemente mit dem Basiselement verriegelbar. In der geschlossenen Position der beiden Einschubelemente bilden beide Einschubelemente eine beidseitige Hinterschneidung entlang der Längsöffnung der Führungsschiene.In a further embodiment of the invention, the guide rail has not only two rail parts but three rail parts as a variant, namely a base element and two insertion elements, both insertion elements being rotatably and movably connectable to the base element. The base element is again essentially groove-shaped, but also symmetrical with two mirror-symmetrical legs, which are each implemented to accommodate an insert element. Both insertion elements are essentially L-shaped, and both Legs of the insert element have parts of a swivel joint which, in cooperation with the insert elements and the base element, allow the insert elements to rotate from an open to a closed position. Again, the slide-in elements can be locked with the base element. In the closed position of the two insertion elements, both insertion elements form an undercut on both sides along the longitudinal opening of the guide rail.

In einer Ausführung der Erfindung können Keder aus Gummi oder Kunststoff entlang der Längsöffnung zur Geräuschminderung eingesetzt werden. Der Kunststoff oder Gummi hat jedoch nur diese eine Funktion und hat keinen Einfluss auf die Funktion der Arretierung der Führungsbolzen in der Schiene.In one embodiment of the invention, piping made of rubber or plastic can be used along the longitudinal opening to reduce noise. However, the plastic or rubber has only this one function and has no influence on the function of locking the guide bolts in the rail.

Die erfindungsgemässe Führungsschiene eignet sich in erster Linie für Lamellenstoren. Ein Einsatz für andere Storen, wie Senkrechtstoren oder Markisen ist auch denkbar.The guide rail according to the invention is primarily suitable for slat blinds. Use for other blinds, such as vertical blinds or awnings, is also conceivable.

Weitere Vorteile der Erfindung folgen aus der nachfolgenden Beschreibung, in der die Erfindung anhand von in den schematischen Zeichnungen dargestellten Ausführungsbeispielen näher erläutert wird.Further advantages of the invention follow from the description below, in which the invention is explained in more detail with reference to exemplary embodiments shown in the schematic drawings.

AusfĂĽhrungsbeispiele der ErfindungEmbodiments of the invention

Figur 1a zeigt einen kurzen Abschnitt einer erfindungsgemässen Führungsschiene 1 sowie eine dazugehörige Storenlamelle 2. Die Lamelle 2 weist an ihren schmalen Enden je einen Führungsbolzen mit einem Schaft 3 und einem Kopfteil 4 auf, der in die Führungsschiene 1 eingeführt und dort arretiert werden kann. (In den Figuren sind jeweils nur der Führungsbolzen und die Führungsschiene an einer der schmalen Enden gezeigt.) Die Führungsschiene ist in Figur 1a in einer offenen Position gezeigt, bei der die Längsöffnung L breit genug ist, um den Kopfteil 4 des Führungsbolzens passieren zu lassen. Die Längsöffnung L der Schiene in offener Position wird durch die zwei Teile der Führungsschiene 1 gebildet, einerseits durch die Kante mit Vorsprung oder Hinterschneidung 9 des Halterungs- oder Basiselements 5 und anderseits durch eine Seitenfläche 13 eines Einschubelements 6. Das Einschubelement 6 ist mit dem Halterungs- oder Basiselement 5 drehbar verbunden. Zum Schliessen der Führungsschiene kann das Einschubelement in Richtung des Pfeils A nach aussen gedreht werden. Figure 1a shows a short section of a guide rail 1 according to the invention and an associated blind slat 2. The slat 2 has at its narrow ends a guide pin with a shaft 3 and a head part 4, which can be inserted into the guide rail 1 and locked there. (In the figures, only the guide pin and the guide rail are shown at one of the narrow ends.) The guide rail is in Figure 1a shown in an open position in which the longitudinal opening L is wide enough to allow the head part 4 of the guide bolt to pass. The longitudinal opening L of the rail in the open position is formed by the two parts of the guide rail 1, on the one hand by the edge with a projection or undercut 9 of the holder or base element 5 and on the other hand by a side surface 13 of an insert element 6. The insert element 6 is with the holder - Or base element 5 rotatably connected. To close the guide rail, the insert element can be turned outwards in the direction of arrow A.

Figur 1b zeigt die gleiche Führungsschiene 1 jedoch in einer geschlossenen Position. Hierzu wurde das Einschubelement 6 um eine Längsachse gedreht und mit dem Basiselement 5 verriegelt. In der geschlossenen Position wird die Längsöffnung L' auf der einen Seite wiederum durch den Vorsprung oder Hinterschneidung 9 des Basisteils 5 und auf der anderen Seite durch den Vorsprung 15 am Einschubelement 6. Die Kante 9 und der Vorsprung 15, die beide entlang der gesamten Länge der Führungsschiene 1 verlaufen, bilden. zusammen eine beidseitige Hinterschneidung an der Längsöffnung L'. Durch die Hinterschneidung wird der Kopfteil 4, dessen Breite grösser als die Öffnung L' ist, arretiert während der Schaft 3 des Führungsbolzens entlang der Längsöffnung L' auf und ab gleiten kann und so die Lamellen gehoben und gesenkt werden können.
Figuren 2 und 3 zeigen die zwei Elemente der Führungsschiene separat. Figur 2 zeigt das Basiselement 5, das an ihrer Basisfläche 7 an einer Leibung einer Fenster- oder Türöffnung befestigt werden kann. In der Mitte der Basisfläche 7 verläuft eine Vertiefung 19 mit zwei parallel laufenden Kanten 20, die dazu dienen, einen Schraubenkopf zu versenken und zu verhindern, dass der Kopfteil des Führungsbolzens auf die Schraube trifft und sich dort verhängt. Der Kopfteil eines Führungsbolzens gleitet somit auf den Kanten 20 und die Auf- und Abbewegung der Lamellen wird durch die Schraubenköpfe nicht behindert. Figure 1b shows the same guide rail 1 but in a closed position. For this purpose, the insert element 6 was rotated about a longitudinal axis and locked with the base element 5. In the closed position, the longitudinal opening L 'is again on one side through the projection or undercut 9 of the base part 5 and on the other side through the projection 15 on the insertion element 6. The edge 9 and the projection 15, both along the entire length run the guide rail 1, form. together an undercut on both sides at the longitudinal opening L '. Due to the undercut, the head part 4, the width of which is greater than the opening L ', is locked while the shaft 3 of the guide bolt can slide up and down along the longitudinal opening L' and the slats can thus be raised and lowered.
Figures 2 and 3 show the two elements of the guide rail separately. Figure 2 shows the base element 5, which can be attached to a reveal of a window or door opening on its base surface 7. In the middle of the base surface 7 there is a recess 19 with two parallel edges 20 which serve to countersink a screw head and to prevent the head part of the guide bolt from hitting the screw and being caught there. The head part of a guide pin thus slides on the edges 20 and the up and down movement of the slats is not hindered by the screw heads.

Das Basiselement 5 ist im Wesentlichen Nut-förmig mit der Basisfläche 7, einem ersten Schenkel 8 und einem zweiten Schenkel 10. Die gezeigte Nut-Form verläuft in der Weise entlang der gesamten Länge der Führungsschiene. Am ersten Schenkel 8 ist ein Vorsprung 9 angeordnet, der als erste Hinterschneidung an der Nut dient. Der zweite Schenkel 10 ist zur Aufnahme des Einschubelements 6 gestaltet wie in Figur 3 gezeigt. An seinem Ende weist er insbesondere eine gerundete Kante 11 auf.The base element 5 is essentially groove-shaped with the base surface 7, a first leg 8 and a second leg 10. The groove shape shown runs in this way along the entire length of the guide rail. A projection 9 is arranged on the first leg 8 and serves as the first undercut on the groove. The second leg 10 is designed to receive the insertion element 6 as in FIG Figure 3 shown. In particular, it has a rounded edge 11 at its end.

Das Einschubelement 6 in Figur 3 ist im Wesentlichen L-förmig mit einem ersten Schenkel 12 und einem zweiten Schenkel 13. Wiederum verläuft die gezeigte Kontur über die gesamte Länge des Einschubelements. Der zweite Schenkel 13 weist insbesondere eine gewölbte Kante 14 auf, die der Form der gerundeten Kante 11 am äusseren, freien Ende des Schenkels 10 des Basiselements angepasst ist, sodass sie diese umfassen und sich um diese drehen kann. Durch die gerundeten und entsprechend gewölbten Kanten 14 und 11 lassen sich das Basiselement 5 und das Einschubelement 6 ineinanderschieben und relativ zueinander drehen. Zur Verriegelung der beiden Elemente 5 und 6 ist am Basiselement 5 eine Vertiefung 17 mit einer Kante und entsprechend am Einschubelement 6 ein Vorsprung mit Nase oder Noppe 16 angebracht, die einen Schnappverschluss gewähren. Die gerundete Form mit Kante der Vertiefung 17 zusammen mit der gerundeten Form der Nase 16 gewährleistet, dass die Verriegelung entweder von Hand oder mittels eines geeigneten Werkzeugs gelöst werden kann.The insertion element 6 in Figure 3 is essentially L-shaped with a first leg 12 and a second leg 13. Again, the contour shown runs over the entire length of the insertion element. The second leg 13 has in particular a curved edge 14 which is adapted to the shape of the rounded edge 11 at the outer, free end of the leg 10 of the base element, so that it can encompass it and rotate about it. Due to the rounded and correspondingly curved edges 14 and 11, the base element 5 and the insert element 6 can be pushed into one another and rotated relative to one another. To lock the two elements 5 and 6, a recess 17 with an edge is attached to the base element 5 and, accordingly, a projection with a nose or knob 16 on the insertion element 6, which provide a snap closure. The rounded shape with the edge of the recess 17 together with the rounded shape of the nose 16 ensures that the locking can be released either by hand or using a suitable tool.

Die Figuren 4a-c zeigen die Führungsschiene 1 mit den beiden zusammengeführten Elementen 5 und 6, indem die gewölbte Kante 14 des Einschubelements 5 die gerundete Kante 9 des Basiselements 6 umfasst. Es sind drei verschiedene Positionen dargestellt jeweils mit einem in der Führungsnut platzierten Führungsbolzen 3, 4.
In der offenen Position gemäss Figur 4a ist das L-förmige Einschubelement 6 so gelagert, dass das Einschubelement 6 zum Innenraum der Nut des Basiselements 5 hinzeigt und der Schenkel 13 des Einschubelements 6 parallel zum ersten Schenkel 8 des Basiselements 5 verläuft, wobei die Längsöffnung L zwischen dem Vorsprung 9 und dem Schenkel 13 breiter ist als der Kopfteil 4 des Führungsbolzens.
Die gerundete Kante 14 entlang der Länge des Einschubelements 6 und die gewölbte Kante 11 entlang der Länge des Basiselements 5 bilden in ihrer Zusammenwirkung ein Drehgelenk in der Art eines gerollten Scharniers. Das Einschubelement 6 kann in Richtung des Pfeils A nach aussen gedreht werden, sodass der Schenkel 12 von der Mitte des Basiselements 5 weg nach aussen dreht und der Schenkel 13 zur Lamelle hin gedreht wird. Figur 4b zeigt die beiden Elemente 5 und 6 zum Teil relativ zueinander gedreht, wodurch sich die Öffnung L zwischen Vorsprung 9 und Vorsprung 15 der beiden Elemente 5 und 6 vermindert. Der Vorsprung 18 an der Innenseite des Einschubelements 6 erstreckt sich zur Aussenseite des zweiten Schenkels 10 hin und vermindert die Bewegungsfreiheit der beiden Elemente in dieser Position. Der Vorsprung 18 dient insbesondere dazu, dass sich das Einschubelement 5 seitlich, d.h. quer zur Längsrichtung der Führungsschiene nicht aus dem Basiselement 5 entfernen lässt. Es wird dadurch verhindert, dass während der Montage die beiden Elemente sich voneinander lösen und das Einschubelement zu Boden fallen kann. Dies erleichtert die Montage.
Wird das Einschubelement 6 von Figur 4b weiter in Richtung des Pfeils A nach aussen gedreht, so wird die geschlossene Position in Figur 4c erreicht, indem der Schenkel 13 mit dem Vorsprung 15 des Einschubelements 6 parallel zur Basisfläche 7 verläuft. Der Vorsprung 15 befindet sich dadurch gegenüber dem Vorsprung 9, wodurch die beiden Vorsprünge zusammen die beidseitige Hinterschneidung um die Längsöffnung L' bilden und woran der Kopfteil 4 aufgrund der verminderten Breite der Längsöffnung L' arretiert wird.
Die beiden Elemente 5 und 6 sind mittels der nasenförmigen Kante 16 zusammen mit der Vertiefung oder Ausnehmung 17 am Basiselement 5 verriegelt.
Zum Öffnen der Schiene wird die Verriegelung gelöst, indem das Einschubelement 6 in entgegengesetzter Pfeilrichtung nach innen gedreht wird, sodass der Schenkel 13 in die Nut des Basiselements 5 gebracht wird und der Schenkel 12 von der Basisfläche 7 weg in Richtung der Lamelle gebracht wird.The Figures 4a-c show the guide rail 1 with the two elements 5 and 6 brought together, in that the curved edge 14 of the insertion element 5 comprises the rounded edge 9 of the base element 6. Three different positions are shown, each with a guide pin 3, 4 placed in the guide groove.
In the open position according to Figure 4a the L-shaped insertion element 6 is mounted such that the insertion element 6 points towards the interior of the groove of the base element 5 and the leg 13 of the insertion element 6 runs parallel to the first leg 8 of the base element 5, the longitudinal opening L between the projection 9 and the leg 13 is wider than the head part 4 of the guide pin.
The rounded edge 14 along the length of the insertion element 6 and the curved edge 11 along the length of the base element 5 form a swivel joint in the manner of a rolled hinge. The insertion element 6 can be turned outwards in the direction of arrow A, so that the leg 12 extends outwards from the center of the base element 5 rotates and the leg 13 is rotated towards the slat. Figure 4b shows the two elements 5 and 6 partially rotated relative to each other, whereby the opening L between projection 9 and projection 15 of the two elements 5 and 6 is reduced. The projection 18 on the inside of the insert element 6 extends to the outside of the second leg 10 and reduces the freedom of movement of the two elements in this position. The projection 18 serves in particular to ensure that the insertion element 5 cannot be removed from the base element 5 laterally, that is to say transversely to the longitudinal direction of the guide rail. This prevents the two elements from separating from one another during assembly and the insertion element falling to the ground. This makes assembly easier.
If the insertion element 6 of Figure 4b further turned in the direction of arrow A, the closed position in Figure 4c achieved by the leg 13 with the projection 15 of the insertion element 6 parallel to the base surface 7. The projection 15 is thereby located opposite the projection 9, as a result of which the two projections together form the undercut on both sides around the longitudinal opening L 'and to which the head part 4 is locked due to the reduced width of the longitudinal opening L'.
The two elements 5 and 6 are locked by means of the nose-shaped edge 16 together with the depression or recess 17 on the base element 5.
To open the rail, the locking is released by rotating the insertion element 6 in the opposite direction of the arrow, so that the leg 13 is brought into the groove of the base element 5 and the leg 12 is brought away from the base surface 7 in the direction of the lamella.

Figuren 5a und b zeigen ein weiteres Ausführungsbeispiel der Erfindung. Sowohl Basis- als auch Einschubelement weisen wiederum die gleichen wesentlichen Formen auf wie das Beispiel aus Figuren 1-4. Dieses Ausführungsbeispiel unterscheidet sich davon in dem Drehgelenk, indem die gerundete Kante und die gewölbte Kante jeweils an dem anderen Element angeordnet sind. Spezifisch weist das Basiselement 5 nun eine gewölbte Kante 14', die eine gerundete Kante 11' am Einschubelement 6 aufweist. Sämtliche andere Teile der Elemente 5 und 6 sind sonst identisch. Figur 5a zeigt das Beispiel in der offenen, Figur 5b in der geschlossenen Position, wobei zum Schliessen der Schiene das Einschubelement 6 wiederum in Richtung des Pfeils A nach aussen gedreht wird und zum Öffnen der Schiene das Einschubelement 6 nach innen gedreht wird, sodass der Schenkel 13 in die Nut des Basiselements 5 gebracht wird. Figures 5a and b show a further embodiment of the invention. Both the base element and the insert element again have the same essential shapes as the example Figures 1-4 , This exemplary embodiment differs from this in the swivel joint in that the rounded edge and the curved edge are each arranged on the other element. Specifically, the base element 5 now has a curved edge 14 ', which has a rounded edge 11' on the insertion element 6. All other parts of elements 5 and 6 are otherwise identical. Figure 5a shows the example in the open, Figure 5b in the closed position, with the insertion element 6 again being turned outwards in the direction of arrow A to close the rail and the insertion element 6 being rotated inwards to open the rail, so that the leg 13 is brought into the groove of the base element 5.

Figuren 6a und 6 zeigen ein Ausführungsbeispiel der Erfindung. Wiederum ist hier wie im Beispiel aus Figur 5a und b das Drehgelenk mit gewölbter Kante 14' am Basiselement 5 und gerundete Kante 11' am Einschubelement 6 realisiert besitzt zeigt aber eine Variante des Vorsprungs zur Verminderung der Beweglichkeit auf. Ein Vorsprung 18' ist hierzu an der Aussenseite der gewölbten Kante 14' angeordnet und erstreckt sich zur Innenseite des Schenkels 12 des Einschubelements 6 hin. Figures 6a and 6 show an embodiment of the invention. Again it is like in the example Figure 5a and b the swivel joint with a curved edge 14 'on the base element 5 and a rounded edge 11' on the insertion element 6 has a variant of the projection to reduce mobility. For this purpose, a projection 18 ′ is arranged on the outside of the curved edge 14 ′ and extends towards the inside of the leg 12 of the insert element 6.

Die Ausführungsbeispiele wie in Figuren 1-7 gezeigt können alle mit Kedern entlang der Längsöffnung L, L' ausgerüstet werden. Die Keder 21 bestehend aus Gummi oder Kunststoff können an den Vorsprüngen 15 und 9 befestigt werden und dienen der Verminderung der Geräusche, die durch Anschlagen und Gleiten des Schafts 3 und Kopfteils 4 des Führungsbolzens an selben Vorsprüngen verursacht würden.The embodiments as in Figures 1-7 shown all can be equipped with piping along the longitudinal opening L, L '. The piping 21 made of rubber or plastic can be attached to the projections 15 and 9 and serve to reduce the noise that would be caused by the abutment and sliding of the shaft 3 and head part 4 of the guide pin on the same projections.

Figur 7a und b zeigen ein weiteres Ausführungsbeispiel der erfindungsgemässen Führungsschiene 1, wobei zur Verriegelung eines Einschubelements 60 im Basiselement 5 anstelle eines Schnappverschlusses eine im Basiselement 5 angeordnete Blattfeder 27 angeordnet ist. Das Basiselement 5 ist wiederum Nut-förmig mit einer Basisfläche 7, einem erstem Schenkel 8 mit Vorsprung 9 zwecks erster Hinterschneidung der Nut 5 und einem zweiten Schenkel 10. Eine gerundete Kante 11" dient dem einen Teil des Drehgelenks oder Längsgelenks zwischen Einschub- und Basiselement. Das Einschubelement 60 weist einen Schenkel 13 mit Vorsprung 15 auf und eine gewölbte Kante 14" als zweiter Teil des Drehgelenks, welche die gerundete Kante 11" am Basiselement 5 umfasst und zwecks seiner Drehung lagert. Da die Blattfeder 27 die Verriegelung der beiden Schienenteile 5 und 60 gewährleistet, ist ein zweiter Schenkel am Einschubelement 60 nicht notwendig. In der offenen Position der Führungsschiene 1 gemäss Figur 7a ist das Einschubelement 60 zum Innenraum der Nut des Basiselements 5 nach innen gedreht, wodurch der Schenkel 13 des Einschubelements 60 die Blattfeder 27 an den zweiten Schenkel 10 des Basiselements 5 drückt. Nach Einführung eines Führungsbolzens einer Storenlamelle wird die Blattfeder 27 entspannt, indem das Einschubelement durch Drehung nach aussen in Richtung des Pfeils A um das Längsgelenk in seine geschlossene Position gemäss Figur 7b gebracht. In der geschlossenen Position bildet der Vorsprung 15 zusammen mit dem Vorsprung 9 am Basiselement 5 die beidseitige Hinterschneidung der Führungsschiene zur Arretierung des Kopfteils eines Führungsbolzens.
Gleichsam wie in den Ausführungsbeispielen aus Figuren 4-6 können wiederum an den Vorsprüngen 9 und 15 Keder 21 angeordnet sein. Hierzu sind die Vorsprünge 9 und 15 an Basis- und Einschubelement mit entsprechenden Nuten 22 ausgestaltet, um die Keder aufzunehmen wie in Figur 2 und 3 gezeigt. Figure 7a and b show a further exemplary embodiment of the guide rail 1 according to the invention, a leaf spring 27 arranged in the base element 5 being arranged in the base element 5 in order to lock an insertion element 60 in the base element 5. The base element 5 is again groove-shaped with a base surface 7, a first leg 8 with a projection 9 for the first undercut of the groove 5 and a second leg 10. A rounded edge 11 ″ serves as part of the swivel joint or longitudinal joint between the insert and the base element The insertion element 60 has a leg 13 with a projection 15 and a curved edge 14 "as the second part of the swivel joint, which encompasses the rounded edge 11" on the base element 5 and supports it for its rotation. Since the leaf spring 27 locks the guaranteed two rail parts 5 and 60, a second leg on the insertion element 60 is not necessary. In the open position of the guide rail 1 according to Figure 7a the insertion element 60 is rotated inwards to the interior of the groove of the base element 5, as a result of which the leg 13 of the insertion element 60 presses the leaf spring 27 against the second leg 10 of the base element 5. After the introduction of a guide pin of a blind lamella, the leaf spring 27 is relaxed by the insertion element being rotated outward in the direction of arrow A around the longitudinal joint into its closed position Figure 7b brought. In the closed position, the projection 15 forms, together with the projection 9 on the base element 5, the undercut on both sides of the guide rail for locking the head part of a guide bolt.
As in the exemplary embodiments Figures 4-6 can in turn be arranged on the projections 9 and 15 piping 21. For this purpose, the projections 9 and 15 on the base and insert element are designed with corresponding grooves 22 in order to receive the piping as in FIG Figures 2 and 3 shown.

In den gezeigten Ausführungsbeispielen kann jeweils am Basiselement 5 eine weitere Befestigungsnut 30 angeordnet sein, die einer stirnseitigen Befestigung an einer Leibung anstelle der Befestigung an der Basisfläche 7 dient.In the exemplary embodiments shown, a further fastening groove 30 can be arranged in each case on the base element 5, which serves for an end-side fastening on a reveal instead of the fastening on the base surface 7.
