Because of this bolt connection, the intermediate guide piece 12 can be pivoted about the axis of this bolt in the bore 20 in the vertical plane during assembly. In the course of assembly, the intermediate guide piece 12 is initially held only on this pivot connection at 20 on the bearing bracket 11, so that it can be held projecting downward from the frame plane and the assembly of the other guide pieces of the first guide and the second guide is particularly facilitated.

  • the web part 18 has a bore which corresponds to an elongated hole running in the web part longitudinal direction or to a plurality of bores arranged one behind the other in this direction of the leg of the bearing bracket which projects perpendicularly from the frame plane. After inserting a screw bolt through the bore of the web part 18 and the elongated hole or one of the bores in series in the protruding leg of the bearing bracket 11, the shaft bearing 19 can be set in an adjusted spacing to the frame level on the bearing bracket 11.

Abstract

Sectional overhead garage door for low lintel heights, with the door leaf members of which, except for the one that is uppermost in the closed position, being guided in guide rails having a vertical, an arcuate, and a horizontal section, and with rollers of the uppermost door leaf member being guided in two guide rails, extending with an approximately horizontal section above and in parallel to the approximately horizontal primary guide section provided on the same side, and each of these being connected to an intermediate guide member adapted to be lowered from the horizontal in the direction of the upper frame zone, so that the uppermost door leaf member, when the door leaf is transferred into the closed position, passes into the plane of the closed door leaf along a shorter path than the remaining door leaf members. The arrangement of the intermediate guide member for the rollers of the uppermost door leaf member is such that a weight balancing shaft, torsion springs, and the rollers can be attached at a lower level. This is achieved by providing the intermediate guide member for the rollers of the uppermost door leaf member as well as the torsion shaft bearing at special bearing brackets in the two upper corner zones of the door frame, and fashioning the intermediate guide members with a linear zone between end sections that are of a curved and, respectively, angled configuration.

Description

Die Erfindung bezieht sich auf ein Deckengliedertor bzw. ein Führungszwischenstück der Führung für die in den oberen Eckbereichen des in der Schließstellung obersten Torblattgliedes vorgesehenen Laufrollen.The invention relates to a ceiling link gate or a guide intermediate piece of the guide for the rollers provided in the upper corner regions of the top door leaf link in the closed position.

Solche Deckengliedertore, bei denen die in den oberen Eckbereichen des in der Schließlage obersten Torblattgliedes vorgesehenen Laufrollen in gesonderten Führungen gehalten sind, die von der üblichen Führung für die Rollen der daran nach unten anschließenden Torblattglieder getrennt geführt sind, gibt es im Stand der Technik in vielfacher Ausführung (z.B. US-A 4 119 133). Die Führungszwischenstücke zwischen dem horizontalen Führungsabschnitt für diese Laufrollen des obersten Torblattgliedes und der Zarge sind dabei bogenförmig ausgeführt, und zwar in einem Bogen eines grösseren Radius als der Bogen der Überbrückungsabschnitte für die Führung der Laufrollen der übrigen Torblattglieder. Diese Überbrückungsabschnitte in ihrer gebogenen Form sind nicht nur schwierig herzustellen, sie beeinträchtigen aufgrund ihrer konvexen Form gegenüber der Decke des mit dem Torblatt zu verschließenden Raumes auch eine hinsichtlich der Sturzhöhe der Toröffnung raumsparende Anordnung der Gewichtsausgleichseinrichtung für das Torblatt in Form einer Welle mit darauf angeordneten Torsionsfedern und beidendig vorgesehenen Seiltrommeln.Ceiling link gates of this type, in which the rollers provided in the upper corner areas of the topmost door leaf member in the closed position are held in separate guides, which are guided separately from the usual guide for the rollers of the door leaf members adjoining them downwards, exist in the prior art in many different ways Execution (e.g. US-A 4 119 133). The intermediate guide pieces between the horizontal guide section for these rollers of the top door leaf member and the frame are designed in an arc shape, in an arc of a larger radius than the arc of the bridging sections for guiding the rollers of the other door leaf members. These bridging sections in their curved shape are not only difficult to manufacture, they also, because of their convex shape relative to the ceiling of the space to be closed with the door leaf, impair a space-saving arrangement of the weight compensation device for the door leaf in the form of a shaft with torsion springs arranged thereon in terms of the lintel height of the door opening and rope drums provided on both ends.

Bei den bekannten Deckengliedertoren dieser Bauart ist darüber hinaus die Montage unhandlich, weil die Anbringung der Führungsschienen und der Gewichtsausgleichseinrichtung durch Zusammensetzen von Einzelteilen erfolgt, und zwar zum Teil in schwieriger räumlicher Zuordnung und Zusammensetzung.In the known overhead sectional doors of this type, the assembly is also unwieldy because the guide rails and the weight compensation device are attached by assembling individual parts, in some cases with difficult spatial assignment and composition.

Mit der Erfindung soll ein Tor dieser Art zur Verfügung gestellt werden, das unter Verwendung einfach, kompakt und präzise herzustellender Teile aufgebaut ist, das auch bei geringer Höhe des Einbauraumes zwischen der oberen Abschlußkante der zu ver schließenden Toröffnung und der Decke des mit dem Tor abzuschließenden Raumes eingebaut werden kann und das sich mit weitgehend vormontierten Teilen besonders einfach am Einsatzort anbringen läßt.With the invention, a gate of this type is to be made available, which is constructed using simple, compact and precisely manufactured parts which, even with a small height of the installation space between the upper end edge of the gate opening to be closed and the ceiling of the gate to be closed Space can be installed and can be particularly easily attached to the site with largely pre-assembled parts.

Dies wird erfindungsgemäß zum einen dadurch erreicht, daß sowohl das Führungszwischenstück für die Laufrollen des in der Schließstellung obersten Torblattgliedes als auch die Torsionswellenlagerung an besonderen, in den beiden oberen Eckbereichen der Torzarge angebrachten Lagerkonsolen gehalten sind und daß die Führungszwischenstücke mit einem geradlinigen Bereich zwischen gekrümmt bzw. abgewinkelt ausgebildeten Endabschnitten ausgeformt sind.This is achieved according to the invention in that both the guide intermediate piece for the rollers of the uppermost door leaf member in the closed position and the torsion shaft bearing are held on special bearing brackets attached in the two upper corner areas of the door frame and that the guide intermediate pieces are curved or with a rectilinear area angled end sections are formed.

Bevorzugte Ausführungen der Erfindung ergeben sich aus den Unteransprüchen im Zusammenhang mit dem in der Zeichnung wiedergegebenen Ausführungsbeispiel, auf das besonders Bezug genommen wird und dessen nachfolgende Beschreibung die Erfindung näher erläutert.Preferred embodiments of the invention result from the subclaims in connection with the embodiment shown in the drawing, to which particular reference is made and the following description of which explains the invention in more detail.

Figur 1 zeigt als Anwendungsbeispiel ein Sektionaltor im geschlossenen Zustand. Das Torblatt besteht aus einer Anzahl von Paneelen, die aufeinanderfolgend aneinander angelenkt sind. Das oberste Paneel 4 ist an seiner Oberkante über besondere Rollen 8 in den seitlichen Zweitführungsschienen gehalten, die jeweils aus einem horizontal und geradlinig verlaufenden Abschnitt 10 und einem als Führungszwischenstück 12 ausgebildeten zargenseitigen Abschnitt bestehen. Die übrigen Paneele 4' und 4" sind über hinsichtlich ihres Abstandes einstellbare Rollen 8' in den beidseitig des Torblattes verlaufenden Erstführungsschienen gehalten, die jeweils aus einem etwa vertikalen Abschnitt 5, einem sich daran anschließenden bogenförmigen Übergangsführungsabschnitt 6 und einem horizontalen Abschnitt 7 bestehen, welch letzterer sich etwa parallel zur Garagendecke erstreckt.Figure 1 shows an application example of a sectional door in the closed state. The door leaf consists of a number of panels which are connected to one another in succession. The top panel 4 is held at its upper edge by means of special rollers 8 in the side secondary guide rails, each of which consists of a horizontally and rectilinear section 10 and a frame-side section designed as a guide intermediate piece 12. The remaining panels 4 'and 4 "are held via rollers 8' with respect to their spacing in the first guide rails running on both sides of the door leaf, each of which consists of an approximately vertical section 5, an adjoining arcuate transition guide section 6 and a horizontal section 7, which the latter extends approximately parallel to the garage ceiling.

Zum Gewichtsausgleich ist eine Torsionsfedereinrichtung 40 vorgesehen, die sich oberhalb des Führungszwischenstückes 12 der Zweitführungsschienen über die zu schließende Toröffnung hinweg erstreckt und beidseits jeweils außerhalb des Torblattes Trommeln 41 aufweist, auf welche jeweils ein Zugseil 42 auf- und abwickelbar ist. Je nach vorhandenem Platz läuft das Seil 42 entweder an der der Toröffnung zugewandten Seite oder an der dem Garageninneren zugewandten Seite auf die Trommeln auf. Im letzteren Falle sind die Seilenden über Laschen am untersten Torpaneel 4" befestigt, welche die jeweils zugehörige Führungsschiene übergreifen. Diese Anordnung erlaubt es, die Torsionsfedereinrichtung mit den Trommeln besonders nahe und damit raumsparend an der die Toröffnung aufweisenden Wand anzuordnen.To balance the weight, a torsion spring device 40 is provided which extends above the intermediate guide piece 12 of the second guide rails over the door opening to be closed and has drums 41 on both sides outside the door leaf, onto each of which a pull rope 42 can be wound and unwound. Depending on the available space, the rope 42 runs onto the drums either on the side facing the door opening or on the side facing the inside of the garage. In the latter case, the rope ends are fastened to the lowest gate panel 4 ″ via lugs, which overlap the associated guide rail. This arrangement allows the torsion spring device with the drums to be arranged particularly close and thus space-saving on the wall having the gate opening.

Ein derartiges Tor kann von Hand bedienbar sein, man kann aber auch einen Antrieb vorsehen, wie er bei 44 angedeutet ist.Such a gate can be operated by hand, but it is also possible to provide a drive as indicated at 44.

Die perspektivische Darstellung gemäß Figur 2 des einen Eckbereiches der Zarge mit einer Lagerkonsole 11 wiederholt sich in spiegelsymmetrischer Anordnung in dem anderen Eckzargenbereich. Die Konsole 11 ist als Winkelstück ausgeführt, deren einer parallel zur Zargenebene verlaufender Schenkel an der Zarge festgelegt ist und deren anderer, etwa senkrecht von der Zargenebene nach innen hin abstrebender Schenkel Befestigungsausbildungen für die Gewichtsausgleichswelle 43 und das Führungszwischenstück 12 für die Laufrollen des in der Schließlage obersten Torblattgliedes haltert. Das zargenseitige Ende des Führungszwischenstückes 12 ist mit einer hinsichtlich der Vertikalrichtung der Zarge unteren Bohrung 20 versehen, durch die ein nicht dargestellter Schraubbolzen geführt ist der eine entsprechende Bohrung (nicht sichtbar) in einem senkrecht von der Zargenebene abstrebenden Schenkelbereich der Lagerkonsole 11 in deren unterem Bereich durchgreift. Aufgrund dieser Schraubbolzenverbindung ist bei der Montage das Führungszwischenstück 12 um die Achse dieses Schraubbolzens in der Bohrung 20 in vertikaler Ebene verschwenkbar. Im Zuge der Montage wird das Führungszwischenstück 12 zunächst nur über diese Schwenkverbindung bei 20 an der Lagerkonsole 11 gehalten, so daß es gegenüber der Zargenebene nach unten abragend gehalten werden kann und die Montage der übrigen Führungsstücke der Erstführung und der Zweitführung in besonderem Maße erleichtert. Nach Vollendung dieser Montage der Führungsabschnitte wird der gesamte Führungsrahmen nach oben verschwenkt, so daß eine im oberen zargenseitigen Endbereich an einer Laschenausbildung vorgesehene Bohrung 26 des Führungszwischenstückes 12 mit einer Bohrung 27 in der Lagerkonsole 11 korrespondiert. Durch die korrespondierenden Öffnungen 26 und 27 wird ein Schraubbolzen geführt, wodurch die Winkelstellung zwischen dem Führungszwischenstück 12 und der Zargenebene festgelegt wird.The perspective view according to FIG. 2 of one corner area of the frame with a bearing bracket 11 is repeated in a mirror-symmetrical arrangement in the other corner frame area. The bracket 11 is designed as an angle piece, one of the legs running parallel to the frame plane is fixed to the frame and the other, approximately vertically striving from the plane of the frame towards the inside fastening designs for the counterbalance shaft 43 and that Intermediate guide piece 12 for the rollers of the top door leaf member in the closed position. The frame-side end of the guide intermediate piece 12 is provided with a lower bore 20 with respect to the vertical direction of the frame, through which a screw bolt (not shown) is guided, which has a corresponding bore (not visible) in a leg region of the bearing bracket 11 that struts perpendicularly from the frame plane in its lower region reaches through. Because of this bolt connection, the intermediate guide piece 12 can be pivoted about the axis of this bolt in the bore 20 in the vertical plane during assembly. In the course of assembly, the intermediate guide piece 12 is initially held only on this pivot connection at 20 on the bearing bracket 11, so that it can be held projecting downward from the frame plane and the assembly of the other guide pieces of the first guide and the second guide is particularly facilitated. After completion of this assembly of the guide sections, the entire guide frame is pivoted upward, so that a bore 26 provided in the upper frame-side end region on a tab design of the intermediate guide piece 12 corresponds to a bore 27 in the bearing bracket 11. A screw bolt is guided through the corresponding openings 26 and 27, as a result of which the angular position between the intermediate guide piece 12 and the frame plane is fixed.

Die Gewichtsausgleichswelle ist weitgehend vormontiert, je nach Länge allenfalls in Längsrichtung unterteilt, derart, daß der an den dargestellten Eckbereich anschließende Wellenbereich in vormontiertem Zustand mit Torsionswelle 40 und Seiltrommel 41 über das Wellenlager 19 an der Lagerkonsole 11 festgelegt werden kann. Das Wellenlager 19 umfaßt vorzugsweise ein in Richtung der Torsionsfeder abstrebendes Konusteil für die Aufnahme des angrenzenden Federendes und ist mit einem Wälzlager für die Welle 43 versehen. Das Wellenlager 19 ist mit einem radial abstrebenden Stegteil 18 versehen, das flächig ausgebildet ist und in seinen Längskantenbereichen Führungen bildet. Zur Erhöhung der Biegesteifigkeit ist dieses Stegteil 18 mit von seiner Fläche abstehenden rippenartigen Vorsprüngen versehen. Der von der Zargenebene abstrebende Schenkel der Lagerkonsole 11, die vorzugsweise aus Blech besteht, ist mit hakenförmig aus der Schenkelebene vorstehend ausgebildeten Laschen 16 und 17 versehen, die zwischen ihrer Endbereichs-Innenseite und der angrenzenden Schenkelfläche Führungsnuten definieren, in die die Längskanten des Stegteils 18 des Wellenlagers 19 einführbar sind. Dabei ist die oben gelegene Lasche 16 näher an der Zarge ausgebildet als die unten gelegene Lasche 17, so daß die Verbindungslinie zwischen den Laschen einen größeren Abstand ergibt als die Breite des Stegteiles 18 des Wellenlagers 19. Das Stegteil 18 kann somit schräg von oben bequem in den nutförmigen Eingriff mit den Laschen eingeführt werden; nach der Einführung wird die Welle bzw. das Wellenlager 19 abgesenkt, so daß das Stegteil 18 unter günstiger Drehmomentverteilung in den nutförmigen Eingriff zwischen dem senkrecht zur Zargenebene abstehenden Schenkel der Lagerkonsole 11 und den daraus ausgeformten Laschen 16 und 17 zur Anlage kommt. Das Stegteil 18 weist eine Bohrung auf, die mit einer in Stegteillängsrichtung verlaufenden Langlochbohrung oder mit mehreren in dieser Richtung hintereinander angeordneten Bohrungen des senkrecht von der Zargenebene abstehenden Schenkels der Lagerkonsole korrespondiert. Nach Einführen eines Schraubbolzens durch die Bohrung des Stegteils 18 und die Lang lochbohrung bzw. eine der in Reihe liegenden Bohrungen im abstehenden Schenkel der Lagerkonsole 11 kann das Wellenlager 19 in justierter Beabstandung zu der Zargenebene an der Lagerkonsole 11 festgelegt werden.The counterbalance shaft is largely preassembled, depending on the length, at most divided in the longitudinal direction, in such a way that the shaft region adjoining the corner region shown can be fixed in the preassembled state with the torsion shaft 40 and cable drum 41 via the shaft bearing 19 on the bearing bracket 11. The shaft bearing 19 preferably comprises a conical part striving in the direction of the torsion spring for receiving the adjacent spring end and is provided with a roller bearing for the shaft 43. The shaft bearing 19 is provided with a radially strutting web part 18, which is flat and forms guides in its longitudinal edge regions. To increase the bending stiffness, this web part 18 is provided with rib-like projections projecting from its surface. The leg of the bearing bracket 11 striving from the frame plane, which preferably consists of sheet metal, is provided with hook-shaped tabs 16 and 17, which define guide grooves between the inside of their end region and the adjacent leg surface into which the longitudinal edges of the web part 18 of the shaft bearing 19 are insertable. The upper tab 16 is formed closer to the frame than the lower tab 17, so that the connecting line between the tabs results in a greater distance than the width of the web part 18 of the shaft bearing 19. The web part 18 can thus be inclined comfortably from above the groove-shaped engagement with the tabs are introduced; after the introduction, the shaft or the shaft bearing 19 is lowered so that the web part 18 comes into contact with the groove-shaped engagement between the leg of the bearing bracket 11 projecting perpendicularly to the frame plane and the tabs 16 and 17 formed therefrom with favorable torque distribution. The web part 18 has a bore which corresponds to an elongated hole running in the web part longitudinal direction or to a plurality of bores arranged one behind the other in this direction of the leg of the bearing bracket which projects perpendicularly from the frame plane. After inserting a screw bolt through the bore of the web part 18 and the elongated hole or one of the bores in series in the protruding leg of the bearing bracket 11, the shaft bearing 19 can be set in an adjusted spacing to the frame level on the bearing bracket 11.

Im Zuge der beginnenden Montage wird das Führungszwischenstück 12 zunächst nur hinsichtlich seiner Bohrung 20 mit Hilfe eines Schraubbolzens an der Lagerkonsole 11 gelenkig festgelegt, so daß es nach schräg unten abragend mit den übrigen Führungsteilen verbunden werden kann. Danach wird die gesamte Führung und damit das Führungszwischenstück 12 in vertikaler Ebene aufwärts verschwenkt, so daß die Bohrung 26 in dem stegförmig vorspringenden Bereich des als Druckgußteil ausgebildeten Führungszwischenstückes 12 mit der bohrung 27 in der Lagerkonsole 11 in fluchtende Übereinstimmung gelangt. Ein auf die Zarge zu gerichteter, aus der Verschwenkrichtung seitlich abgebogener Führungslappen 28 erleichtert die Einnahme der endgültigen Verschwenkstellung des Führungszwischenstückes 12 zu der Lagerkonsole 11. Nach Einführen eines Bolzens durch die nunmehr in fluchtende Übereinstimmung gebrachten Bohrungen 26 und 27 ist das Führungszwischenstück 12 winkelgetreu an der Lagerkonsole 11 festgelegt.In the course of the beginning of the assembly, the intermediate guide piece 12 is initially only articulated with respect to its bore 20 with the aid of a screw bolt on the bearing bracket 11, so that it can be connected to the other guide parts in a protruding manner at an angle. Thereafter, the entire guide and thus the guide intermediate piece 12 is pivoted upward in the vertical plane, so that the bore 26 in the web-shaped projecting region of the guide intermediate piece 12 designed as a die-cast part comes into flush agreement with the bore 27 in the bearing bracket 11. A guide tab 28 directed towards the frame and laterally bent from the pivoting direction makes it easier to take the final pivoting position of the intermediate guide piece 12 to the bearing bracket 11. After inserting a bolt through the bores 26 and 27, which are now aligned, the guide intermediate piece 12 is at the correct angle Bearing bracket 11 set.

Figur 3 zeigt eine Seitenansicht des Führungszwischenstückes 12, aus der hervorgeht, daß dieses Zwischenstück an seinen beiden Endbereichen gekrümmt bzw. abgewinkelt ausgebildet ist. Im rechts dargestellten Bereich ist die Bohrung 20 vorgesehen, die die im Zuge der Montage schwenkbare Schraubverbindung zu der Lagerkonsole 11 schafft. Die Bohrung 20 ist im in der Betriebsstellung nach unten gerichteten Endbereich 13 vorgesehen, der unter einem wenig größer als 90° betragenden Winkel in den geradlinig ausgebildeten Abschnitt 15 des Führungszwischenstückes 12 übergeht. Anderen Endes mündet das Führungszwischenstück 12 in eine etwa horizontal verlaufende, nicht dargestellte Führung (Zweitführungsabschnitt 10 in Figur 1), und zwar über ei nen leicht gewölbten Endbereich 14, an welchem außenseitig des Führungsraumes eine Anschlußplatte 22 ausgebildet ist. Die Anschlußplatte trägt eine Reihe von Bohrungen, die der Verbindung des Führungszwischenstückes 12 mit dem ihr zugeordneten, etwa horizontal verlaufenden Führungsabschnitt 10 einerseits und dem parallel dazu darunter verlaufenden Führungsagbschnitt 7 für die Laufrollen der übrigen Torblattglieder dient und mit entsprechend angeordneten Schraubbolzen-Durchführungsöffnungen versehen ist. Im Anfangsbereich des geradlinig verlaufenden Abschnittes 15 des Führungszwischenstückes 12 sind nach unten abragende Haltelappen 23 und 24 ausgebildet, die den nicht dargestellten kreisbogenförmigen Übergangsführungsabschnitt 6 zwischen dem horizontal verlaufenden Führungsabschnitt 7 einerseits und dem vertikal verlaufenden Führungsabschnitt 5 andererseits der Laufrollen der übrigen Torblattglieder zwischen sich stabilisierend aufnehmen (Figur 1). Ebenfalls in diesem Anfangsbereich des geradlinig verlaufenden Längsabschnittes 15 des Führungszwischenstückes 12 ist ein nach oben hin abragender Abschnitt 25 mit einer hinterschnitten ausgebildeten Nutöffnung ausgeformt, in die das freie Ende einer Betätigungsleine für die handbetätigte Bewegung des Torblattes eingeführt werden kann.Figure 3 shows a side view of the guide intermediate piece 12, from which it can be seen that this intermediate piece is curved or angled at its two end regions. In the area shown on the right, the bore 20 is provided, which creates the screw connection to the bearing bracket 11 which can be pivoted during the assembly. The bore 20 is provided in the end region 13 which is directed downward in the operating position and which merges into the rectilinear section 15 of the intermediate guide piece 12 at an angle slightly greater than 90 ° . At the other end, the guide intermediate piece 12 opens into an approximately horizontally running guide (not shown) (second guide section 10 in FIG. 1), namely via a slightly curved end region 14, on which a connecting plate 22 is formed on the outside of the guide space. The connection plate carries a series of bores, which serves to connect the intermediate guide piece 12 to its associated, approximately horizontally running guide section 10, on the one hand, and the guide section 7, which runs parallel to it below, for the rollers of the other door leaf members and is provided with correspondingly arranged screw-through openings. In the beginning of the straight line extending section 15 of the guide intermediate piece 12 are formed downwardly projecting retaining tabs 23 and 24, which receive the circular arc-shaped transition guide section 6, not shown, between the horizontal guide section 7 on the one hand and the vertical guide section 5 on the other hand, the rollers of the other door leaf members between them stabilizing (Figure 1) . Also in this initial region of the straight longitudinal section 15 of the guide intermediate piece 12 is an upwardly projecting section 25 with an undercut groove opening into which the free end of an operating line for the manual movement of the door leaf can be inserted.

Von dem horizontalen Führungsabschnitt 10 für die Laufrollen des in der Schließstellung obersten Torblattgliedes 4 aus gesehen ist der geradlinige Längsabschnitt 15 des Führungszwischenstückes 12 nur leicht aus der Horizontalen nach unten zur Zarge hin geneigt ausgebildet, d.h. das an den horizontalen Führungsabschnitt 10 anschließende bogenförmige Endstück des Endbereiches 14 schließt mit dem geradlinigen Längsabschnitt 15 einen sehr großen stumpfen Winkel ein.As seen from the horizontal guide section 10 for the rollers of the top door leaf member 4 in the closed position, the straight longitudinal section 15 of the intermediate guide piece 12 is only slightly inclined downwards from the horizontal towards the frame, i.e. the arcuate end piece of the end region 14 adjoining the horizontal guide section 10 encloses a very large obtuse angle with the straight longitudinal section 15.

Im zargenseiten Endbereich ist das Führungszwischenstück 12 mit einem geradlinig nach unten hin gerichteten Führungsendbereich 13 ausgebildet, der mit der Längsachse des geradlinig verlaufenden Längsabschnittes 15 des Zwischenstückes 12 einen stumpfen Winkel einschließt, der nur wenig größer als 90° beträgt. Dieser etwa senkrecht parallel zur Seitenzarge verlaufende Endbereich 13 nimmt die Laufrollen 8 des in der Schließlage obersten Torblattes 4 dann auf, wenn das Tor handbetätigt bewegbar ausgebildet ist. Dann nämlich stützen sich diese Laufrollen 8 des obersten Abschnittes an der etwa vertikal verlaufenden, dem zu verschließenden Raum zugewandten Wandungsabschnitt 29 ab, so daß das in der Schließlage oberste Torblattglied 4 nicht von außen her in das Rauminnere bzw. in den Bereich des geradlinig verlaufenden Längsabschnittes 15 des Führungszwischenstückes 12 überführt werden kann. Ein befugtes und gezieltes Öffnen des Torblattes verlangt demnach, daß das Torblatt zu Beginn der Öffnungsbewegung leicht angehoben wird. Ist anstelle des Handbetriebes ein etwa horizontal geführter motorischer Antrieb 44 für das Torblatt vorgesehen, so müssen die Laufrollen 8 des in der Schließlage obersten Torblattgliedes 4 dieser horizontalen Antriebsbewegungsrichtung folgen können. Das bedeutet, daß die Laufrollen 8 des in der Schließlage obersten Torblattgliedes 4 unter horizontaler Zugbeanspruchung in den geradlinig verlaufenden Längsabschnitt 15 des Zwischenführungsstückes 12 gelangen können. Die Untersetzung dieses motorischen Torantriebes stellt für diesen Fall sicher, daß eine Druckbeanspruchung von der Außenseite des Torblattes bzw. des in der Schließlage obersten Torblattgliedes 4 nicht zu dessen Öffnungsbewegung führen kann.In the frame-side end area, the guide intermediate piece 12 is formed with a straight downward guide end area 13, which includes an obtuse angle with the longitudinal axis of the straight longitudinal section 15 of the intermediate piece 12, which is only slightly greater than 90 ° . This end region 13, which extends approximately perpendicularly to the side frame, receives the rollers 8 of the top door leaf 4 in the closed position when the door is designed to be movable by hand. Then these rollers 8 of the uppermost section are supported on the approximately vertically running wall section 29 facing the room to be locked, so that the topmost door leaf member 4 in the closed position does not enter the interior of the room or the area of the linear longitudinal section 15 of the intermediate guide piece 12 can be transferred. Authorized and targeted opening of the door leaf therefore requires that the door leaf be slightly raised at the beginning of the opening movement. If an approximately horizontally guided motor drive 44 is provided for the door leaf instead of manual operation, then the rollers 8 of the top door leaf member 4 in the closed position must be able to follow this horizontal drive movement direction. This means that the rollers 8 of the uppermost door leaf member 4 in the closed position can reach the straight longitudinal section 15 of the intermediate guide piece 12 under horizontal tensile stress. The reduction of this motorized door drive ensures in this case that a pressure load from the outside of the door leaf or the top door leaf member 4 in the closed position cannot lead to its opening movement.

Um wahlweise die Handbetätigung und die motorische Betätigung des Torblattes einstellen zu können, sind die Laufrollen 8 in den oberen Seitenbereichen des in der Schließlage obersten Torblattgliedes 4 derart einstellbar, daß sie bei Handbetrieb in dem vertikalen Abschnitt 29 des Endbereiches 13 der Führungszwischenstücke 12 anliegen, während sie bei motorischem Antrieb höher gesetzt in der Schließlage derart gehalten sind, daß eine etwa horizontale Zugbeanspruchung durch den motorischen Antrieb die Laufrollen in den geradlinigen Längsabschnitt 15 der Führungszwischenstücke 12 gelangen lassen. Die Laufrollen 8 sind zu die sem Zwecke in einer vertikalen Ebene beliebig verstellbar angeordnet, dies insbesondere über eine Kreuzschlittenführung 45 zwischen der Achshalterung dieser Laufrollen 8 und ihrem Basisteil, das mit dem obersten Torblattglied 4 verbunden ist (Fig. 1). Auf diese Weise läßt sich nicht nur das jeweilige Erfordernis nach Handbetrieb oder Motorbetrieb erfüllen, es ist darüber hinaus zusätzlich eine Justiermöglichkeit für die exakte Einstellung des in der Schließlage obersten Torblattgliedes hinsichtlich der Torblattebene in der Schließstellung gegeben.In order to be able to selectively set the manual actuation and the motorized actuation of the door leaf, the rollers 8 in the upper side areas of the uppermost door leaf member 4 in the closed position are adjustable such that they rest in the vertical section 29 of the end region 13 of the guide intermediate pieces 12 during manual operation, while they are held higher in the closed position in the case of a motor drive in such a way that an approximately horizontal tensile stress caused by the motor drive allows the rollers to reach the straight longitudinal section 15 of the guide intermediate pieces 12. The rollers 8 are arranged for this purpose in a vertical plane adjustable, in particular via a cross slide guide 45 between the axle bracket of these rollers 8 and its base part, which is connected to the uppermost door leaf member 4 (Fig. 1). In this way, not only can the respective need for manual operation or motor operation be met, there is also an adjustment option for the exact setting of the uppermost door leaf member in the closed position with respect to the door leaf level in the closed position.

Die über den Großteil hinweg zwischen den Endbereichen geradlinig ausgeführte Ausbildung des Führungszwischenstückes hat nicht nur den Vorteil einer niedrigeren Gewichtsausgleichswellen-Anordnung zur Folge, sie ist auch für den Fall besonders vorteilhaft, daß dieses Führungszwischenstück in bevorzugter Ausführung der Erfindung als Gußteil, insbesondere als Zink-Druck-Gußteil, ausgebildet ist. Wie die Linien X und Y in Figur 3 erkennen lassen, lassen sich im Zuge der Herstellung geradlinig geteilte Kerne verwenden, die problemlos nach der gußtechnischen Herstellung entfernbar sind. Es entstehen lediglich im Bereich des Überganges zwischen dem geradlinig verlaufenden Längsabschnitt 15 und dem demgegenüber zargenseitig verhältnismäßig kraß abgebogenen Endteil 13 scharfkantige Übergänge an den innenseitigen Führungsflächen dieses Zwischenstücks, die der abrundenden Nachbearbeitung bedürfen.The straightforward design of the guide intermediate piece over the majority between the end regions not only has the advantage of a lower counterbalance shaft arrangement, it is also particularly advantageous in the case that this guide intermediate piece in a preferred embodiment of the invention is a cast part, in particular a zinc Pressure casting, is formed. As can be seen from the lines X and Y in FIG. 3, cores which are divided in a straight line can be used in the course of the production and can be removed without problems after the production by casting. Only in the area of the transition between the straight longitudinal section 15 and the end part 13, which is relatively bluntly bent on the frame side, do sharp-edged transitions occur on the inside guide surfaces of this intermediate piece, which require rounding-off processing.
