Abstract

In a sliding window or the like, consisting of a continuous frame and of at least two window wings displaceable within the frame, the wings being guided by guides or the like arranged parallel to one another, and overlapping slightly in the closed position, and a bolt, which can block the closed position and be secured by means of a lock, being arranged at the overlap point, in order to obtain an at least approximately dust-proof and water-tight closure even in the region of the wing overlap, there is provided as a bolt an approximately Z-shaped sectional bar (6) which has the same length as the overlappable wing edges and which is mounted transversely to the direction of displacement of the wings (2, 3) and on the window frame (1) between the wings (2, 3) so as to be pivotable to a limited extent about its longitudinal axis, in such a way that the sectional-bar flanges (14) offset relative to one another by the amount of the degree of overlap of the closed wings (2, 3) are directed approximately parallel to the direction of displacement of the wings, between the wings (2, 3), in one pivoting end position and in the other pivoting end position bear against the mutually confronting end faces (7, 8) of the closed wings (2, 3) over the entire length of the end faces. <IMAGE>

Description

Durch diese Maßnahmen wird der gesamte Spalt zwischen den in der Schließlage befindlichen Schiebeflügeln mit der Profilleiste abgedeckt, wobei letzterer über die gesamte Länge der einander zugewandten Flügelstirnseiten an diesen anliegt und damit auch ein Verkanten der Schiebeflügel relativ zu ihren Führungen ausschließt und somit auch das unbefugte Öffnen der Schiebeflügel erschwert. By doing this, the entire gap between the Sliding leaves located in the closed position are covered with the profile strip, with the latter over the entire length of the wing faces facing each other on these is applied and thus tilting of the sliding sash relative to their guides and thus also makes it more difficult for unauthorized opening of the sliding sashes.

Eine im Sinne der Aufgabenstellung förderliche Weiterbildung besteht darin, daß die Profilleiste an die freien Ränder der S-Form anschließende, in Horizontalrichtung der S-Form verlaufende Randleisten aufweist, die einen derartigen Abstand voneinander aufweisen, daß diese die Stirnseitenbereiche der geschlossenen Schiebeflügel umgreifen und an den einander abgewandten Schiebeflügelseiten anliegen. There is further training that is conducive to the task at hand in that the profile strip adjoins the free edges of the S-shape, in the horizontal direction the S-shaped edge strips which are spaced from one another at such a distance have that these encompass the end face areas of the closed sliding sash and rest against the sides of the sliding sash facing away from each other.

Hierdurch wird mit der Profilleiste auch verhindert, daß die geschlossenen Schiebeflügel gewaltsam durchgebogen werden können, um durch den nunmehr vergrößerten Spalt zwischen den überlappenden Flügel rändern hindurchgreifen zu können. This also prevents the closed with the profile strip Sliding sashes can be forcibly bent to get through the now enlarged To be able to reach through the gap between the overlapping wing edges.

Darüber hinaus können durch diese Maßnahmen Toleranzen in der Dicke der Schiebeflügel ausgcglichen werden.-wobei innerhalb des Toleranzbereiches ein zumindest annähernd staubdichter Verschluß sichergestellt ist. In addition, these measures can result in tolerances in the thickness the sliding sashes are compensated.-within the tolerance range at least approximately dust-tight closure is ensured.

Auch werden die -Flügelrandteile beim Schließen der Profilleiste durch die Wölbungen lagerichtig an die Profilleiste angelegt, und zwar auch dann, wenn zum Beispiel die Scheiben mittig durchgebogen sein sollten. The wing edge parts also become when the profile strip is closed due to the curvatures placed in the correct position on the profile strip, even then, if, for example, the panes should be bent in the middle.

Hierzu kennzeichnet sich eine bevorzugte Weiterbildung dadurch, daß der Schwenkachse der Profilleiste benachbarte Rinnenflanken der Innenwölbungen der Profilleiste jeweils exzenterartig mit zur Innenwölbung hin zunehmenden Spannhub erzeugend gekrümmt profiliert sind. To this end, a preferred development is characterized in that the pivot axis of the profile strip adjacent channel flanks of the inner curvature of the Profile strip each eccentric with increasing clamping stroke towards the inside curvature are profiled generating curved.

Zur weiteren Erhöhung der Sicherheit gegen unbefugtes Öffnen kennzeichnet sich eine fertigungsteehnisch günstige Ausgestaltung dadurch, daß der Mittelbereich derS-förmigen Profilleiste von einem längs der Profilleiste gerichteten, über die gesamte Profilleistenlänge sich erstreckenden Kanal durchdrungen isl, durch den eine gegenüber der Profilleiste längere Stange drehfest hindurchgesteckt ist. und daß beide, die Profilleisle stirnseitig überragenden Stangenendteile als Drehzapfen ausgebildet sind, wobei vorzugsweise -ner die Profilleiste als Strangprofilabschnitt, insbesondere aus Leichtmetall, ausgebildet ist, und die Stange aus Stahl besteht. Identifies to further increase security against unauthorized opening a favorable design in terms of manufacturing technology in that the central area derS-shaped profile strip from one directed along the profile strip, over the entire profile strip length extending channel isl penetrated by the a rod that is longer than the profile strip is inserted through it so that it cannot rotate. and that both rod end parts protruding from the front side of the profile rail as pivot pins are formed, preferably -ner the profile strip as an extruded profile section, in particular made of light metal, and the rod is made of steel.

Eine bevorzugte<Gestaltung des Organes zur Verdrehung der Profilleiste besteht darin, daß als Betätigungsteil für die Profilleiste ein von dieser quer abstrebender Hebel angeordnet ist, der einen der ortsfesten Rahmenschenkel nach außen gerichtet durchgreift, wobei vorzugsweise ferner der Hebel in -der Schließlage der Profilleiste mit der Rahmenaußenseite bündig abschließend ausgebildet ist, und am Hebel ein die Schließstellung sicherndes, mit dem Rahmen korrespondierendes Schloß gehaltert ist. A preferred <design of the organ for rotating the profile strip consists in that as an actuating part for the profile strip one of this transversely striving lever is arranged, which one of the stationary frame legs after extends through directed outwards, preferably also the lever in the closed position the profile strip is designed to be flush with the outside of the frame, and on the lever a lock that secures the closed position and corresponds to the frame is held.

Weiterhin ist es zur Verbesserung der Abdichtung der Flügel im Bereich ihrer -Überlappung vorteilhaft, wenn an den Bereichen der Profilleiste, die mit den Stirnseiten der Schiebeflügel zusammenwirken, ein elastisch nachgiebiges Dichtmittel angeordnet ist. It is also used to improve the sealing of the wings in the area their overlap advantageous if on the areas of the profile strip that with the end faces of the sliding sash cooperate, an elastically flexible sealant is arranged.

Damit wird auch die Gefahr einer Beschädigung der Flügel durch die Profilleiste erheblich vermindert. This also reduces the risk of damage to the wings by the Profile strip considerably reduced.

Zudem können damit auch Toleranzen ausgeglichen werden. In addition, it can also be used to compensate for tolerances.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben. Es zeigt F i g. 1 einen Tcil eincs Vitrinenschiebefensters tn der Vorderansicht: Fig. 2 desgleichen in Richtung der Linie ll-ll gesehen; Fig. 3 desglcichen in Richtung der Linie 111-111 gesehen, teilweise aufgebrochen. An embodiment of the invention is shown in Drawings shown and is described in more detail below. It shows F i g. 1 part of a showcase sliding window In the front view: FIG. 2 likewise seen in the direction of the line II-II; Fig. 3 also seen in the direction of the line 111-111, partially broken away.

Hierbei sind in einem rechteckigen Rahmen 1 zwei Schiebeflügel 2 und 3 vorgesehen, die mittels zweier, parallel zueinander angeordnete und am Rahmen 1 befestigte Führungen 4 und 5 verschiebbar geführt sind. Here are two sliding leaves 2 in a rectangular frame 1 and 3 are provided by means of two, arranged parallel to one another and on the frame 1 fixed guides 4 and 5 are slidably guided.

Die Schiebeflügel 2 und 3 überlappen sich in der Schließlage geringfügig, wie aus der F i g. 3 ersichtlich ist. The sliding leaves 2 and 3 overlap slightly in the closed position, as shown in FIG. 3 can be seen.

Die Flügel 2 und 3 sind als ungerahmte Scheiben ausgebildet, die auch, wie dargestellt, aus mehreren dünnen Scheiben zusammengefügt sein können. The wings 2 and 3 are designed as unframed discs that also, as shown, can be assembled from several thin slices.

Im Bcreich der Flügelüberlappung ist zur Verriegelung der Schiebeflügelschließlage eine zur Verschiebcrichtung orthogonal gerichtete, im wesentlichen S-förmigc Profilleiste 6 vorgesehen. In the area of the leaf overlap is for locking the sliding leaf closed position an essentially S-shaped profile strip, oriented orthogonally to the direction of displacement 6 provided.

Diese Profilleiste 6 erstreckt sich über die gesamte Länge der einander zugewandten Flügelstirnseiten 7 und 8 und hat über seine Stirnseiten hinausragende Drehzapfen 9, die in am Rahmen 1 befestigte Drehlager 10 axial unverschieblich eingreifen. This profile strip 6 extends over the entire length of each other facing wing end faces 7 and 8 and has protruding beyond its end faces Trunnions 9, which engage in the pivot bearing 10 attached to the frame 1 in an axially immovable manner.

Die Profilleiste 6 ist durch Strangpressen aus Leichtmetall hergestellt und hat einen dessen Steg 11 längsdurchdringenden, angeformten Kanal 12, durch welchen eine vielkantige Stange 13 aus Stahl unverdrehbar hindurchgesteckt ist, deren über die Stirnseite der Profilleiste hinausreichende Endteile als Drehzapfen ausgebildet sind. The profile strip 6 is produced from light metal by extrusion and has an integrally formed channel 12 which extends longitudinally through the web 11 and through which a polygonal rod 13 made of steel is inserted non-rotatably, the over the end face of the profile strip reaching out end parts designed as pivot pins are.

In den den Flügelstirnseiten 7 Lind 8 zugewandten Seiten der Profilleistenflansche t4 sind Innenwölbungen 15 angeformt. In the sides of the profile strip flanges facing the wing end faces 7 and 8 t4 inner bulges 15 are formed.

Die Flanken 16 und 17 sind zueinander gerichtet angeordnet und die Profilbreite der Innenwölbung ist kleiner als die Dicke der Schiebeflügel 2 bis 3, so daß, wie aus der F i g. 3 ersichtlich, die Flügelrandteile mit ihren stirnseitigen Längskanten an die-Flanken anlegbar sind. The flanks 16 and 17 are arranged facing each other and the The profile width of the inside curvature is smaller than the thickness of the sliding sash 2 to 3, so that, as shown in FIG. 3 can be seen, the wing edge parts with their end faces Long edges can be placed on the flanks.

Während die äußeren Flanken 46 jeweils eben ausgebildet'sind, sind die inneren Flanken 17 jeweils exzenterartig einen zur Innenwölbung 15 hin zunehmenden Spannhub erzeugend gekrümmt profiliert, die das lagerichtige Anlegen der Schiebeflügel 2, 3 an die Flanken erheblich begünstigen. While the outer flanks 46 are each flat, are the inner flanks 17 each increasing like an eccentric towards the inner curvature 15 The clamping stroke is curved and profiled, which enables the sliding sash to be positioned in the correct position 2, 3 favor considerably on the flanks.

Am unteren Drehzapfen 9 der Profilleiste 6 ist ein von dieser quer abstrebender und einen Durchbruch im Rahmen 1 durchgreifender Hebel 18 befestigt, mit dessen Hilfe die Profilleiste 6 aus der unter anderem aus der F i g. 3 ersichtlichen Endlage um 90" in seiner anderen Endlage verdreht werden kann, wobei dann die Profilleistenflansche 14 zur Verschieberichtung der Schiebeflügel2 und 3 parallel und zwischen letzteren verlaufend angeordnet sind, so daß in jener Stellung die Schiebeflügel 2 und 3 verstellt werden können, während in der anderen Endstellung (Fig. 3) die in der Schließlage befindlichen Schiebeflügel 2 und 3 gegen Verschieben gesperrt sind. At the lower pivot 9 of the profile strip 6 one of this is transverse braced and a breakthrough in the frame 1 through-reaching lever 18 attached, with the help of which the profile strip 6 from the inter alia from FIG. 3 can be seen End position can be rotated by 90 "in its other end position, in which case the profile strip flanges 14 parallel to the direction of displacement of the sliding leaves 2 and 3 and between the latter are arranged to run so that the sliding sashes 2 and 3 are adjusted in that position can be, while in the other end position (Fig. 3) in the closed position The sliding sashes 2 and 3 located are locked against moving.

Der Kraftann des Hebels 18 hat eine T-förmige Gestalt und ist ferner so bemessen, daß der Hebel 18 in der Schließlage mit der Rahmenaußenseite bündig abschließt. The Kraftann of the lever 18 has a T-shaped shape and is further dimensioned so that the lever 18 is flush with the outside of the frame in the closed position concludes.

Am Hebel 18 ist ein schlüsselbetätigbares Schloß 19 befestigt, dessen Riegel 20 in der Schließlage mit dem Rahmen I zusammenwirkt und mit dessen Hilfe die Schließlage des Hebels 18 gesichert werden kann. On the lever 18 a key-operated lock 19 is attached, the Latch 20 interacts in the closed position with the frame I and with its help the The closed position of the lever 18 can be secured.

Im Rahmen der Erfindung ist auch eine andere Gestaltung des Stellorganes zur manuellen oder maschinellen Verdrehung der Profilleiste 6, zum Beispiel in Form eines auf dem Lagerzapfen 9 verdrehfest angeordneten Stellrades möglich. Another design of the actuator is also within the scope of the invention for manual or machine rotation of the profile strip 6, for example in shape an adjusting wheel arranged non-rotatably on the bearing pin 9 is possible.

Die Ausgestaltung der Flügelführungen ist beliebig. The wing guides can be designed as desired.
