Description

Die vorliegende Erfindung betrifft eine Anordnung umfassend eine SchutztÞr und eine zugehÃķrige TÞrzarge, eine SchutztÞr fÞr eine solche Anordnung, eine TÞrzarge fÞr eine solche Anordnung, eine Verriegelungseinheit fÞr eine solche Anordnung sowie ein Kit zum UmrÞsten einer SchutztÞr mit zugehÃķriger TÞrzarge zu einer solchen Anordnung gemÃĪss den Oberbegriffen der unabhÃĪngigen AnsprÞche.The present invention relates to an arrangement comprising a protective door and an associated door frame, a protective door for such an arrangement, a door frame for such an arrangement, a locking unit for such an arrangement and a kit for converting a protective door with associated door frame to such an arrangement according to the Preambles of the independent claims.

SchutztÞren kommen im allgemeinen dort zum Einsatz, wo miteinander verbundene GebÃĪudebereiche fÞr den Fall eines Brandes brandschutzmÃĪssig voneinander trennbar sein mÞssen, z.B. um ein Eindringen von Rauch in weitere GebÃĪudeteile und/oder eine Ausdehnung des Feuers zu verhindern. Solche SchutztÞren und die zugehÃķrigen TÞrzargen bestehen in den meisten FÃĪllen aus Metallprofilen, was dazu fÞhrt, dass sich diese bei einer starken einseitigen ErwÃĪrmung, wie sie.im Brandfall in der Regel auftritt, bogenfÃķrmig verbiegen. Bei zur Kaltseite hin Ãķffnenden TÞren mit fest an einer GebÃĪudewand angeschlossenen TÞrzargen kann dies bei sehr hohen TÞren mÃķglicherweise dazu fÞhren, dass trotz eingerasteter TÞrfalle unzulÃĪssig grosse Spalte zwischen TÞr und TÞrzarge entstehen, so dass die Schutzfunktion der SchutztÞren stark beeintrÃĪchtigt wird. Um dies zu verhindern, werden bei derartigen TÞren heute Mehrfach-Verriegelungen eingesetzt, welche jedoch insbesondere bei elektrisch entriegelbaren TÞren, wie z.B. Zutrittskontrollen, zu erheblichen Mehrkosten und zu einer erhÃķhten StÃķranfÃĪlligkeit fÞhren und zudem gegenÞber Systemen mit einer einzigen TÞrfalle erhÃķhte SchliessgerÃĪusche verursachen. Zudem sind die bekannten Systeme ungeeignet fÞr Anwendungsbereiche, bei denen die TÞr im Normalbetrieb nicht durch eine TÞrfalle zugehalten wird, wie z.B. bei PendeltÞren.Protective doors are generally used where interconnected building areas in the event of a fire must be fireproof separable from each other, for example, to prevent the ingress of smoke into other parts of the building and / or expansion of the fire. Such protective doors and the associated door frames are in most cases made of metal profiles, with the result that these bend in an arc-shaped manner with a strong one-sided heating, as they typically occur in the event of fire. In the case of doors opening to the cold side with door frames firmly connected to a building wall, this can possibly lead to inadmissibly large gaps between the door and the door frame, even if the door catch is latched, so that the protective function of the safety doors is severely impaired. To prevent this, multi-latches are used in such doors today, however, which lead in particular in electrically unlockable doors, such as access controls, to significant additional costs and increased susceptibility to interference and also cause increased locking noise compared to systems with a single door trap. In addition, the known systems are unsuitable for applications in which the door is not locked in normal operation by a door latch, such as swing doors.

Es stellt sich daher die Aufgabe, eine Anordnung mit einer SchutztÞr und einer zugehÃķrigen TÞrzarge zur VerfÞgung zu stellen, welche die Nachteile des Standes der Technik nicht aufweist oder diese zumindest teilweise vermeidet.It is therefore the object to provide an arrangement with a protective door and an associated door frame available, which does not have the disadvantages of the prior art, or at least partially avoids.

Diese Aufgabe wird von der Anordnung, der SchutztÞr, der TÞrzarge, der Verriegelungseinheit sowie dem Kit gemÃĪss den unabhÃĪngigen AnsprÞchen gelÃķst.This object is achieved by the arrangement, the protective door, the door frame, the locking unit and the kit according to the independent claims.

Ein erster Aspekt der Erfindung betrifft eine Anordnung umfassend eine SchutztÞr mit einer dazugehÃķrigen TÞrzarge. An der SchutztÞr oder an der TÞrzarge ist ein Verriegelungsorgan angeordnet, welches bei einer starken ErwÃĪrmung der Umgebung der SchutztÞr, z.B. infolge eines Feuers in deren NÃĪhe, einen Formschluss in TÞrÃķffnungsrichtung zwischen der geschlossenen SchutztÞr und der TÞrzarge herstellt. Dabei wird das Verriegelungsorgan mittels einer durch diese ErwÃĪrmung erzeugten WÃĪrmedehnung fester und/oder flÞssiger Stoffe betÃĪtigt, z.B. durch ein Bimetall-Element, durch einen DehnstoffkÃķrper oder auf hydraulischem Wege durch Ausdehnung einer FlÞssigkeit, so dass sich eine Zwangskopplung von ErwÃĪrmung und BetÃĪtigung des Verriegelungsorgans ergibt.A first aspect of the invention relates to an arrangement comprising a protective door with an associated door frame. On the protective door or on the door frame, a locking member is arranged, which in a strong heating of the environment of the protective door, e.g. As a result of a fire in their vicinity, creates a positive connection in the door opening direction between the closed protective door and the door frame. In this case, the locking member is actuated by means of a thermal expansion of solid and / or liquid substances generated by this heating, e.g. by a bimetal element, by a DehnstoffkÃķrper or hydraulically by expansion of a liquid, so that there is a forced coupling of heating and actuation of the locking member.

Durch die erfindungsgemÃĪsse Anordnung wird es mÃķglich, TÞrsysteme zur VerfÞgung zu stellen, welche zuverlÃĪssig, kostengÞnstig und wartungsarm sind und im Brandfall ein Auseinanderklaffen von SchutztÞr und TÞrzarge - auch als TÞrflÞgelversatz bezeichnet - zumindest im Bereich des Verriegelungsorgans verhindern oder auf ein zulÃĪssiges bzw. gewolltes Mass begrenzen.The arrangement according to the invention makes it possible to provide door systems which are reliable, cost-effective and low-maintenance and, in the event of fire, prevent the protective door and door frame from divergence - also referred to as the door leaf offset - at least in the area of the locking element or at an admissible or desired level limit.

In einer bevorzugten AusfÞhrungsform der Anordnung ist das Verriegelungsorgan bimetallbetÃĪtigt, was den Vorteil hat, dass auf einfache Weise relativ grosse BetÃĪtigungswege mÃķglich sind.In a preferred embodiment of the arrangement, the locking member is bimetallbetÃĪtigt, which has the advantage that in a simple manner relatively large actuation paths are possible.

In einer weiteren bevorzugten AusfÞhrungsform ist das Verriegelungsorgan ein an der SchutztÞr oder an der TÞrzarge beweglich gelagertes Bauteil, welches im Brandfall mittels eines separat ausgebildeten, auf dem Prinzip der WÃĪrmedehnung basierenden, bevorzugterweise bimetallischen BetÃĪtigungsorgans infolge ErwÃĪrmung desselben von einer Ruheposition, in welcher es ein Öffnen und Schliessen der SchutztÞr nicht behindert, in eine Verriegelungsposition, in welcher es durch den Formschluss ein Öffnen der SchutztÞr verhindert oder auf ein konstruktiv vorgesehenes TÞrflÞgelversatzmass begrenzt, bewegt wird. Auf diese Weise wird es mÃķglich, die Verriegelungsfunktion von der BetÃĪtigungsfunktion zu trennen, so dass die die jeweilige Funktion wahrnehmenden Bauteile optimal ausgelegt werden kÃķnnen.In a further preferred embodiment, the locking member is a movably mounted on the protective door or on the door frame component, which in case of fire by means of a separately formed on the Principle of thermal expansion based, preferably bimetallic actuator due to heating of the same from a rest position in which it does not hinder opening and closing of the protective door, in a locking position in which it prevents opening of the protective door by the positive locking or limited to a structurally provided TÞrflÞgelsatzsatzmass, is moved. In this way it becomes possible to separate the locking function from the actuation function, so that the components which perceive the respective function can be optimally designed.

Bevorzugterweise wird dabei das Verriegelungsorgan als Schieber, bevorzugterweise als Riegelbolzen ausgebildet, welcher im Brandfall durch das BetÃĪtigungsorgan axial verschoben wird. Solche Verriegelungsorgane benÃķtigen nur geringe BetÃĪtigungskrÃĪfte und ertragen gleichzeitig relativ grosse Beanspruchungen.Preferably, the locking member is designed as a slide, preferably as a locking bolt, which is axially displaced by the actuator in case of fire. Such locking members require only low actuation forces and at the same time endure relatively high stresses.

Mit Vorteil wird das Verriegelungsorgan an einer AussenflÃĪche der SchutztÞr oder der TÞrzarge angeordnet, z.B. aussen am oberen Rahmenprofil, und zwar derart, dass es bei einer ErwÃĪrmung des BetÃĪtigungsorgans im Brandfall im wesentlichen senkrecht zur TÞrÃķffnungsrichtung verschoben oder verschwenkt wird und dadurch einen Vorsprung bildet, der mit einem entsprechenden AnschlagkÃķrper den gewÞnschten Formschluss in TÞrÃķffnungsrichtung herstellen kann.Advantageously, the locking member is disposed on an outer surface of the protective door or door frame, e.g. outside on the upper frame profile, in such a way that it is displaced or pivoted at a heating of the actuator in case of fire substantially perpendicular to the door opening direction and thereby forms a projection which can produce the desired positive locking in the door opening direction with a corresponding stop body.

Dabei ist es bevorzugt, dass das BetÃĪtigungsorgan auf der AussenflÃĪche der SchutztÞr oder der TÞrzarge angeordnet ist, so dass es sich im Brandfall mÃķglichst rasch erwÃĪrmen kann. Mit Vorteil sind das Verriegelungsorgan und das BetÃĪtigungsorgan zusammen als eigenstÃĪndige Verriegelungseinheit ausgebildet, welche, bevorzugterweise mit einem eigenen GehÃĪuse, z.B. mittels Schrauben oder Nieten, auf der AussenflÃĪche der TÞr oder TÞrzarge befestigt ist. Hierdurch ergibt sich der Vorteil, dass auf spezielle Anschlagbleche verzichtet werden kann und eine Anordnung der Verriegelungseinheit an einem Ort an der SchutztÞr bzw. der TÞrzarge mÃķglich ist, welcher im Brandfall sehr frÞh eine starke ErwÃĪrmung erfÃĪhrt, so dass sich sehr kurze Reaktionszeiten realisieren lassen.It is preferred that the actuator is arranged on the outer surface of the protective door or door frame, so that it can heat up as quickly as possible in case of fire. Advantageously, the locking member and the actuator are formed together as an independent locking unit, which, preferably with its own housing, for example by means of screws or rivets, is mounted on the outer surface of the door or door frame. This has the advantage that it can be dispensed with special stop plates and an arrangement of the locking unit at a location on the Protective door or the door frame is possible, which in the case of fire very early undergoes a strong warming, so that can be realized very short reaction times.

Alternativ ist es auch bevorzugt, wenn sich das Verriegelungsorgan an einer StirnflÃĪche der SchutztÞr befindet, also an einer den TÞrumfang bildenden FlÃĪche, oder an einer InnenflÃĪche der TÞrzarge, welche bei geschlossener SchutztÞr einer StirnflÃĪche der SchutztÞr gegenÞberliegt. Dabei ist es derart angeordnet, dass es bei einer ErwÃĪrmung seines BetÃĪtigungsorgans im Brandfall im wesentlichen senkrecht zur TÞrÃķffnungsrichtung aus dieser StirnflÃĪche oder InnenflÃĪche nach aussen geschoben oder geschwenkt wird. Hierdurch wird eine Verriegelung im Bereich der sich gegenÞberstehenden Profilkonturen von SchutztÞr und TÞrzarge mÃķglich, wodurch auf aussen an der SchutztÞre oder an der TÞrzarge angebrachte Bauteile, welche mÃķglicherweise optisch stÃķrend wirken, verzichtet werden kann.Alternatively, it is also preferred if the locking member is located on an end face of the protective door, that is to say on a surface forming the door circumference, or on an inner surface of the door frame which, when the protective door is closed, faces an end face of the protective door. It is arranged such that it is pushed out or pivoted outwardly from this end face or inner surface in case of fire substantially perpendicular to the door opening direction upon heating of its actuating member. As a result, a lock in the region of the opposing profile contours of the protective door and door frame is possible, which on the outside of the protective door or on the door frame mounted components, which may be optically disturbing, can be dispensed with.

Dabei ist bevorzugt, wenn das bevorzugterweise bimetallische BetÃĪtigungsorgan aussen auf der StirnflÃĪche der SchutztÞr oder auf der die TÞrÃķffnung begrenzenden InnenflÃĪche der TÞrzarge angeordnet ist, z.B. bei geschlossener SchutztÞr direkt gegenÞberliegend einer StirnflÃĪche derselben, da sich hierdurch gute Reaktionszeiten erzielen lassen und das BetÃĪtigungsorgan bei geschlossener SchutztÞr nicht sichtbar ist.It is preferred if the preferably bimetallic actuator outside on the end face of the protective door or on the door opening defining the inner surface of the door frame is arranged, for. when the door is closed directly opposite a face of the same, as this can achieve good reaction times and the actuator is not visible when the protective door is closed.

Mit Vorteil ist das BetÃĪtigungsorgan als Bimetall-Lasche ausgebildet, welche an einer ihrer beiden Enden, gegebenenfalls Þber weitere Bauteile, fest mit der SchutztÞr bzw. der TÞrzarge verbunden ist, z.B. mittels einer Befestigungsschraube oder einer Popniete. Das andere Ende ist mit dem Verriegelungsorgan gekoppelt, so dass die gesamte temperaturbedingte FormÃĪnderung des Bimetall-Elements fÞr die Bewegung des Verriegelungsorgans gegenÞber der SchutztÞr bzw. der TÞrzarge nutzbar ist und entsprechend grosse Bewegungswege mÃķglich sind.Advantageously, the actuator is designed as a bimetallic tab, which is connected at one of its two ends, optionally via other components, fixed to the protective door or the door frame, for example by means of a fastening screw or a pop rivet. The other end is coupled to the locking member, so that the entire temperature-induced change in shape of the bimetallic element for the movement of the locking member relative to the protective door or the door frame is usable and correspondingly large movement paths are possible.

Dabei ist es bevorzugt, wenn das Verriegelungsorgan als Riegelbolzen mit einem in einem Bereich sprunghaft reduzierten Querschnitt ausgebildet ist, bevorzugterweise mit einer umlaufenden Nut, und die Bimetall-Lasche einen endseitigen, bevorzugterweise in LÃĪngsrichtung verlaufenden, bevorzugterweise nach aussen offenen Schlitz aufweist, in welchem der im Querschnitt reduzierte Bereich des Riegelbolzens angeordnet ist. Hierdurch lassen sich das als Riegelbolzen ausgebildete Verriegelungsorgan und das als Bimetall-Lasche ausgebildete BetÃĪtigungsorgan auf einfache und zuverlÃĪssige Weise sowohl in BetÃĪtigungsrichtung des Riegelbolzens als auch in der entgegengesetzten Richtung formschlÞssig koppeln, so dass der Riegelbolzen nach einem AbkÞhlen der Bimetall-Lasche von dieser wieder zurÞck in die Ruheposition gebracht wird, die Verriegelung also automatisch wieder aufgehoben wird.It is preferred if the locking member is designed as a locking bolt with a discontinuously reduced in a range cross section, preferably with a circumferential groove, and the bimetallic flap has an end, preferably extending in the longitudinal direction, preferably outwardly open slot in which the is arranged in reduced cross-sectional area of the locking bolt. As a result, the locking member designed as a locking bolt and designed as a bimetallic actuator can be positively and reliably coupled both in the direction of actuation of the locking bolt and in the opposite direction, so that the locking bolt after cooling the bimetallic flap of this back is brought into the rest position, so the lock is automatically canceled.

In noch einer weiteren bevorzugten AusfÞhrungsform der Anordnung ist das Verriegelungsorgan derartig angeordnet, dass es im Brandfall einen Formschluss zwischen SchutztÞr und TÞrzarge im Bereich der TÞroberkante, bevorzugterweise in der den TÞrbÃĪndern abgewandten HÃĪlfte der TÞroberkante bzw. im oberen Bereich der TÞrvorderkante bewirkt, da die wÃĪrmebedingte Verformung der TÞre in diesem Bereich typischerweise am grÃķssten ist.In yet another preferred embodiment of the arrangement, the locking member is arranged such that it causes a positive connection between the protective door and door frame in the area of TÜberberkante, preferably in the door hinges facing away from half of the upper edge of the door or in the upper region of the door leading edge in case of fire, since the heat-related Deformation of the door in this area is typically the largest.

Dabei ist es von Vorteil, wenn zusÃĪtzlich im Schwellenbereich in der den TÞrbÃĪndern abgewandten HÃĪlfte bzw. im unteren Bereich der TÞrvorderkante ein wÃĪrmedehnungsbetÃĪtigtes, bevorzugterweise bimetallisches Verriegelungsorgan angeordnet ist, welches bei einer ErwÃĪrmung im Brandfall auch in diesem Bereich einen Formschluss zwischen SchutztÞr und TÞrzarge bewirkt, um zu verhindern, dass sich ein durch das im oberen Bereich angeordnete Verriegelungsorgan behinderter TÞrflÞgelversatz in den unteren Bereich verlagert und dort zu einem unzulÃĪssig grossen Spalt zwischen SchutztÞr und TÞrzarge fÞhrt. Dabei ist das zusÃĪtzliche Verriegelungsorgan bevorzugterweise identisch ausgebildet und betÃĪtigt wie das im oberen Bereich angeordnete Verriegelungsorgan.It is advantageous if a wÃĪrmedehnungsbetÃĪtigter, preferably bimetallic locking member is additionally arranged in the threshold area in the half facing the door hinges or in the lower region of the door leading edge, which causes a positive connection between the protective door and door frame in case of warming in case of fire in this area, in order to prevent that displaced by the arranged in the upper region locking member obstructed door leaf offset in the lower area and there leads to an unacceptably large gap between the protective door and door frame. In this case, the additional locking member is preferably identically formed and operated as the arranged in the upper region locking member.

Die SchutztÞr ist bevorzugterweise eine metallische BrandschutztÞr oder RauchschutztÞr, bevorzugterweise mit einer Rahmenkonstruktion aus Metallprofilen. Ist zudem die TÞrzarge, welche bevorzugterweise ebenfalls aus Metallprofilen gebildet ist, an einer massiven Tragkonstruktion, wie z.B. einer Wand aus Mauerwerk oder Beton, angeschlossen, so dass ihre temperaturbedingte Verbiegung im Brandfall stark behindert ist, so treten die Vorteile der Erfindung besonders deutlich zu Tage.The protective door is preferably a metallic fire door or smoke protection door, preferably with a frame construction of metal profiles. In addition, if the door frame, which is also preferably formed of metal profiles, on a solid support structure, such. a wall of masonry or concrete, connected so that their temperature-induced bending is severely hampered in case of fire, the benefits of the invention are particularly evident.

In noch einer weiteren bevorzugten AusfÞhrungsform der Anordnung sind das Verriegelungsorgan und die im Brandfall mit diesem einen Formschluss in TÞrÃķffnungsrichtung bildende KÃķrperlichkeit, z.B. ein Anschlagblech, derartig ausgestaltet und angeordnet, dass sich bei einem Anschlagen des Verriegelungsorgans in TÞrÃķffnungsrichtung an der zuvor erwÃĪhnten KÃķrperlichkeit ein bestimmter TÞrflÞgelversatz in TÞrÃķffnungsrichtung ergibt. Bevorzugterweise betrÃĪgt der mÃķgliche TÞrflÞgelversatz jedoch, gemessen im Bereich des Verriegelungsorgans, hÃķchstens 20 mm. Hierdurch ergibt sich der Vorteil, dass eine gewisse Reaktionszeit fÞr die wÃĪrmedehnungsbetÃĪtigte Verriegelung verbleibt, wodurch die Funktionssicherheit deutlich erhÃķht und eine Verlagerung des TÞrflÞgelversatzes in den Schwellenbereich, welche zu unzulÃĪssig grossen Spalten zwischen SchutztÞr und TÞrzarge in diesem Bereich fÞhren kÃķnnte, weitestgehend vermieden wird.In yet a further preferred embodiment of the arrangement, the locking member and the body in the door opening direction, in the event of fire with this one form fit, e.g. a stopper plate, designed and arranged such that results in a striking of the locking member in the door opening direction of the aforementioned corporeality a certain door leaf offset in the door opening direction. Preferably, however, the possible door leaf offset, measured in the region of the locking member, is at most 20 mm. This results in the advantage that a certain reaction time for the thermal expansion-actuated locking remains, whereby the reliability significantly increased and a displacement of the door leaf offset in the threshold area, which could lead to impermissibly large gaps between the protective door and door frame in this area, as far as possible avoided.

Ein zweiter Aspekt der Erfindung betrifft eine SchutztÞr mit mindestens einem wÃĪrmedehnungsbetÃĪtigten, bevorzugterweise bimetallbetÃĪtigten Verriegelungsorgan wie zuvor unter dem ersten Aspekt der Erfindung dargelegt, welches bei ErwÃĪrmung in einer Richtung im wesentlichen senkrecht zur TÞrÃķffnungsrichtung hervortritt, zur ErmÃķglichung einer in TÞrÃķffnungsrichtung formschlÞssigen Verriegelung der SchutztÞr in einer diese umgebenden TÞrzarge im Brandfall. Mit einer solchen SchutztÞr lassen sich, durch HinzufÞgen einer TÞrzarge mit einer geeigneten AnschlagkÃķrperlichkeit fÞr das Verriegelungsorgan, auf einfache und kostengÞnstige Weise erfindungsgemÃĪsse Anordnungen gemÃĪss dem ersten Aspekt der Erfindung bilden.A second aspect of the invention relates to a safety door having at least one thermal expansion actuated, preferably bimetallic locking member as set forth above in the first aspect of the invention, which when heated in a direction substantially perpendicular to the door opening direction, to enable a door-locking positive locking of the safety door in one this surrounding door frame in case of fire. With such a protective door can be formed by adding a door frame with a suitable abutment body for the locking member, in a simple and cost-effective manner inventive arrangements according to the first aspect of the invention.

Ein dritter Aspekt der Erfindung betrifft eine TÞrzarge mit mindestens einem wÃĪrmedehnungsbetÃĪtigten, bevorzugterweise bimetallbetÃĪtigten Verriegelungsorgan wie zuvor unter dem ersten Aspekt der Erfindung dargelegt, welches bei ErwÃĪrmung in einer Richtung im wesentlichen senkrecht zur TÞrÃķffnungsrichtung hervortritt, zur ErmÃķglichung einer in TÞrÃķffnungsrichtung formschlÞssigen Verriegelung einer in der TÞrzarge angeordneten SchutztÞr im Brandfall. Mit einer solchen TÞrzarge lassen sich, durch HinzufÞgen einer SchutztÞr mit einer geeigneten AnschlagkÃķrperlichkeit fÞr das Verriegelungsorgan, auf einfache und kostengÞnstige Weise erfindungsgemÃĪsse Anordnungen gemÃĪss dem ersten Aspekt der Erfindung bilden.A third aspect of the invention relates to a door frame with at least one heat expansion actuated, preferably bimetallic locking member as set forth above in the first aspect of the invention, which emerges when heated in a direction substantially perpendicular to the door opening direction, to enable a positive locking in the door opening direction in the door frame arranged protective door in case of fire. With such a door frame can be, by adding a protective door with a suitable AnschlagkÃķrperlichkeit for the locking member, in a simple and cost-effective manner according to the invention form arrangements according to the first aspect of the invention.

Ein vierter Aspekt der Erfindung betrifft eine Verriegelungseinheit fÞr eine erfindungsgemÃĪsse Anordnung gemÃĪss dem ersten Aspekt der Erfindung, welche ein Verriegelungsorgan und ein wÃĪrmedehnungsbetÃĪtigtes, bevorzugterweise bimetallisches BetÃĪtigungsorgan angeordnet auf einem gemeinsamen TrÃĪger umfasst. Dabei sind das Verriegelungsorgan und das BetÃĪtigungsorgan derartig miteinander gekoppelt, dass eine ErwÃĪrmung des BetÃĪtigungsorgans zu einer Verschiebe- oder Schwenkbewegung des Verriegelungsorgans gegenÞber dem TrÃĪger fÞhrt.A fourth aspect of the invention relates to a locking unit for an inventive arrangement according to the first aspect of the invention, which comprises a locking member and a thermal expansion actuated, preferably bimetallic actuator disposed on a common carrier. In this case, the locking member and the actuating member are coupled to each other in such a way that heating of the actuating member leads to a displacement or pivoting movement of the locking member relative to the carrier.

In einer bevorzugten AusfÞhrungsform der Verriegelungseinheit sind das Verriegelungsorgan und das BetÃĪtigungsorgan in einem gemeinsamen, von der SchutztÞre und der TÞrzarge separat ausgebildeten GehÃĪuse angeordnet, derart, dass eine KÃķrperlichkeit des Verriegelungsorgans mit zunehmender ErwÃĪrmung des BetÃĪtigungsorgans zunehmend Þber die Aussenkontur des GehÃĪuses Þbersteht.In a preferred embodiment of the locking unit, the locking member and the actuating member are arranged in a common, separately formed by the guard door and the door frame, such that a corporeality of the locking member with increasing heating of the actuating member progressively over the outer contour of the housing.

Mit derartigen Verriegelungseinheiten lassen sich auf einfache Weise aus herkÃķmmlichen SchutztÞr- und TÞrzarge-Anordnungen erfindungsgemÃĪsse Anordnungen bilden, indem die Verriegelungseinheit derartig aussen an der SchutztÞr oder an der TÞrzarge befestigt wird, dass im Brandfall ein TÞrflÞgelversatz durch Anschlagen des Verriegelungsorgans an der TÞrzarge (bei an der SchutztÞr befestigter Verriegelungseinheit) oder durch Anschlagen des Verriegelungsorgans an der SchutztÞr (bei an der TÞrzarge befestigter Verriegelungseinheit) verhindert oder auf ein zulÃĪssiges bzw. gewolltes Mass begrenzt wird. Durch das Anbauen der Verriegelungseinheit an eine SchutztÞr oder eine TÞrzarge entsteht zudem eine erfindungsgemÃĪsse SchutztÞr gemÃĪss dem zweiten Aspekt der Erfindung oder eine erfindungsgemÃĪssen TÞrzarge gemÃĪss dem dritten Aspekt der Erfindung.With such locking units can be in a simple manner from conventional safety door and door frame arrangements according to the invention form by the locking unit is attached outside such on the guard or on the door frame, that in case of fire, a door offset by striking the locking member on the door frame (at the protective door attached to the locking unit) or by abutment of the locking member on the protective door (with locking unit attached to the door frame) is prevented or limited to a permissible or intended measure. By attaching the locking unit to a protective door or a door frame also results in an inventive protective door according to the second aspect of the invention or a novel door frame according to the third aspect of the invention.

Ein fÞnfter Aspekt der Erfindung betrifft einen NachrÞstkit zum nachtrÃĪglichen UmrÞsten einer herkÃķmmlichen SchutztÞranordnung zu einer Anordnung gemÃĪss dem ersten Aspekt der Erfindung. Der Kit umfasst einen Riegelbolzen und eine Bimetall-Lasche, welche derartig formschlÞssig koppelbar sind, dass der Riegelbolzen durch temperaturbewirkte FormÃĪnderung der Bimetall-Lasche vor- und zurÞckbewegbar ist.A fifth aspect of the invention relates to a retrofit kit for the retrofitting of a conventional protective door arrangement to an arrangement according to the first aspect of the invention. The kit comprises a locking bolt and a bimetallic tab, which can be coupled in such a form-fitting manner that the locking bolt can be moved forward and backward by temperature-induced change in shape of the bimetal lug.

In einer bevorzugten AusfÞhrungsform des Kits umfasst der Kit zusÃĪtzlich ein einschraubbares oder einpressbares FÞhrungselement fÞr den Riegelbolzen, z.B. eine Gewindeniete, welche in eine BlechprofilflÃĪche einsetzbar ist und nach dem Stauchen, und gegebenenfalls nach einem zusÃĪtzlichen Aufbohren auf den gewÞnschten Durchmesser, als FÞhrung fÞr den Riegelbolzen dienen kann.In a preferred embodiment of the kit, the kit additionally comprises a screw-in or press-in guide element for the locking bolt, e.g. a threaded rivet, which can be used in a metal profile surface and after upsetting, and optionally after an additional drilling to the desired diameter, can serve as a guide for the locking bolt.

Mit solchen Kits lassen sich herkÃķmmliche SchutztÞranordnungen auf einfache und kostengÞnstige Weise zu erfindungsgemÃĪssen Anordnungen gemÃĪss dem ersten Aspekt der Erfindung umrÞsten, wobei die SchutztÞr zu einer erfindungsgemÃĪssen SchutztÞr gemÃĪss dem zweiten Aspekt der Erfindung umgerÞstet wird oder die TÞrzarge zu einer erfindungsgemÃĪssen TÞrzarge gemÃĪss dem dritten Aspekt der Erfindung.With such kits, conventional protective door arrangements can be converted in a simple and cost-effective manner to arrangements according to the invention according to the first aspect of the invention, wherein the protective door to a protective door according to the invention according to the second Aspect of the invention is converted or the door frame to a novel door frame according to the third aspect of the invention.

Eine erste bevorzugte AusfÞhrungsform der erfindungsgemÃĪssen Anordnung ist in den Figuren 1, 2a und 2b dargestellt. Wie aus Fig. 1 hervorgeht, welche eine Vorderansicht der Anordnung darstellt, umfasst die Anordnung eine BrandschutztÞr 1, welche als Rahmenkonstruktion aus Metallprofilen hergestellt ist, und eine zugehÃķrige TÞrzarge 2, ebenfalls aus Metallprofilen, welche fest mit einer GebÃĪudewand 5 aus Beton verbunden ist. Wie in Zusammenschau mit Fig. 2a erkennbar ist, welche einen Teilschnitt durch die Anordnung entlang der Linie A-A in Fig. 1 zeigt, weist die BrandschutztÞr 1 im Bereich ihrer oberen StirnflÃĪche bzw. Oberkante ein wÃĪrmedehnungsbetÃĪtigtes Verriegelungsorgan 3, 4 auf, welches aus einem Riegelbolzen 3 als eigentliches Verriegelungsorgan 3 und einer Bimetall-Lasche 4 als BetÃĪtigungsorgan 4 fÞr den Riegelbolzen 3 besteht.A first preferred embodiment of the inventive arrangement is shown in Figures 1, 2a and 2b. As is apparent from Fig. 1, which shows a front view of the arrangement, the arrangement comprises a fire door 1, which is made as a frame construction of metal profiles, and an associated door frame 2, also made of metal profiles, which is firmly connected to a building wall 5 made of concrete. As in synopsis can be seen, which shows a partial section through the arrangement along the line AA in Fig. 1, the fire door 1 in the region of its upper face or top edge a wÃĪrmedehnungsbetÃĪtigtes locking member 3, 4, which consists of a locking bolt 3 as the actual Locking member 3 and a bimetallic tab 4 as an actuator 4 for the locking bolt 3 consists.

Wie in Zusammenschau mit Fig. 2b ersichtlich ist, welche eine Draufsicht auf denjenigen Abschnitt der oberen StirnflÃĪche zeigt, in welchem der Riegelbolzen 3 und die Bimetall-Lasche 4 angeordnet sind, ist der Riegelbolzen 3 in einer senkrecht zur StirnflÃĪche der BrandschutztÞr 1 bzw. senkrecht zur TÞrÃķffnungsrichtung O verlaufenden FÞhrungsbohrung 6 lÃĪngsverschieblich gelagert. Die Bimetall-Lasche 4 ist an einem ihrer beiden Enden mit einer Schraube 7 flach auf die vom oberen Rahmenprofil gebildete obere StirnflÃĪche der BrandschutztÞr 1 aufgeschraubt und an ihrem anderen Ende formschlÞssig in beiden LÃĪngsverschiebungsrichtungen des Riegelbolzens 3 mit diesem gekoppelt, was im vorliegenden Fall dadurch erfolgt, dass der Riegelbolzen 3 einen im Durchmesser sprunghaft reduzierten Bereich, hervorgerufen durch eine umlaufende Nut, aufweist, welcher in einem endseitig offenen Schlitz 8 in der Bimetall-Lasche 4 angeordnet ist.As can be seen in conjunction with Fig. 2b, which shows a plan view of that portion of the upper end face in which the locking bolt 3 and the bimetallic tab 4 are arranged, the locking bolt 3 in a perpendicular to the end face of the fire door 1 and perpendicular to the door opening direction O extending guide bore 6 mounted longitudinally displaceable. The bimetallic tab 4 is screwed at one of its two ends with a screw 7 flat on the top of the frame profile formed upper end surface of the fire door 1 and positively coupled at its other end in both longitudinal displacement directions of the locking bolt 3 with this, which takes place in the present case in that the locking bolt 3 has a diameter that is reduced in diameter by a circumferential groove, which is arranged in a slot 8 open in the end in the bimetal lug 4.

In der in Fig. 2a dargestellten Situation befindet sich der Riegelbolzen 3 in der Verriegelungsposition und bewirkt so einen Formschluss in TÞrÃķffnungsrichtung O zwischen der SchutztÞr 1 und der TÞrzarge 2, indem er in TÞrÃķffnungsrichtung O an dem Anschlagblech 9 anschlÃĪgt. Dabei ist er durch die infolge starker ErwÃĪrmung nach oben gebogene Bimetall-Lasche 4 axial in dieser Position gehalten und innerhalb der FÞhrungsbohrung 6 radial gefÞhrt. Wie zu erkennen ist, sind im vorliegenden Fall der Riegelbolzen 3 und das Anschlagblech 9 derartig zueinander angeordnet, dass ein TÞrflÞgelversatz X von ca. 15 mm, gemessen im Bereich des Riegelbolzens 3, mÃķglich ist.In the situation shown in Fig. 2a, the locking bolt 3 is in the locked position and thus causes a positive connection in the door opening direction O between the protective door 1 and the door frame 2 by abutting the door 9 in the door opening direction O. He is held axially by the bimetallic flap 4 bent upward due to strong heating in this position and radially guided within the guide bore 6. As can be seen, in the present case, the locking bolt 3 and the stopper plate 9 are arranged to each other such that a door wing offset X of about 15 mm, measured in the region of the locking bolt 3, is possible.

Die Figuren 3a und 3b zeigen Ansichten wie die Figuren 2a und 2b einer zweiten erfindungsgemÃĪssen Anordnung, welche sich von der zuvor gezeigten Anordnung lediglich dadurch unterscheidet, dass hier Rahmenprofile zu Einsatz kommen, welche in dem Bereich, in welchem der Riegelbolzen 3 angeordnet ist, lediglich eine einzige dÞnne Blechlage aufweisen. Da zur FÞhrung des Riegelbolzens 3 eine Bohrung in diesem Blechmaterial nicht ausreichend wÃĪre, kommt hier als FÞhrungselement 10 fÞr den Riegelbolzen 3 eine FÞhrungshÞlse 10 zum Einsatz, welche durch Einpressen und anschliessendes Ausbohren einer Gewindeniete erzeugt wurde.FIGS. 3 a and 3 b show views like FIGS. 2 a and 2 b of a second arrangement according to the invention, which differs from the previously shown arrangement only in that here frame profiles are used which only in the region in which the locking bolt 3 is arranged have a single thin sheet metal layer. Since a bore in this sheet metal material would not be sufficient to guide the locking bolt 3, here comes as a guide element 10 for the locking bolt 3, a guide sleeve 10 is used, which was produced by pressing and then drilling a threaded rivet.

Die Figuren 4a und 4b, 5a und 5b sowie 6a und 6b zeigen jeweils Ansichten wie die Figuren 2a und 2b von weiteren erfindungsgemÃĪssen Anordnungen, denen allen gemeinsam ist, dass sowohl das Verriegelungsorgan 3 als auch das BetÃĪtigungsorgan 4 von einer einzigen KÃķrperlichkeit gebildet sind, nÃĪmlich von einem Bimetall-Streifen 3, 4. Solche Anordnungen weisen nur sehr wenige bewegte Bauteile auf und sind deshalb besonders funktionssicher.Figures 4a and 4b, 5a and 5b and 6a and 6b respectively show views as the figures 2a and 2b of further inventive arrangements, which are common to all that both the locking member 3 and the actuator 4 are formed by a single physicality, namely from a bimetallic strip 3, 4. Such arrangements have very few moving components and are therefore particularly reliable.

Die in den Figuren 4a und 4b dargestellte Anordnung weist einen ÃĪhnlichen Aufbau auf wie die in den Figuren 2a, 2b und 3a, 3b gezeigten Anordnungen, jedoch mit dem zuvor erwÃĪhnten wesentlichen Unterschied, dass hier kein separates Verriegelungsorgan (Riegelbolzen) vorhanden ist, sondern sich der mittels zweier Nieten 11 auf der oberen StirnflÃĪche der TÞr 1 aufgenietete Bimetall-Streifen 3, 4 bei starker ErwÃĪrmung soweit nach oben verbiegt, dass er einen Formschluss in TÞrÃķffnungsrichtung O mit dem Anschlagblech 9 bewirkt und so den mÃķglichen TÞrflÞgelversatz X auf das konstruktiv vorgesehene Mass begrenzt. Diese Situation ist in Fig. 4a dargestellt.The arrangement shown in Figures 4a and 4b has a similar structure as the arrangements shown in Figures 2a, 2b and 3a, 3b, but with the aforementioned essential difference that here no separate locking member (locking bolt) is present, but itself the riveted by means of two rivets 11 on the upper end face of the door 1 bimetallic strip 3, 4 bends so much upward in strong warming that it causes a positive connection in the door opening direction O with the stop plate 9 and so the possible door leaf offset X on the constructive measure provided limited. This situation is shown in Fig. 4a.

Die Figuren 5a und 5b zeigen eine Anordnung ÃĪhnlich der in den Figuren 4a und 4b gezeigten Anordnung, welche sich jedoch von der letztgenannten dadurch unterscheidet, dass der Bimetall-Streifen 3, 4 nicht quer zur TÞrÃķffnungsrichtung O sondern lÃĪngs zu dieser auf der oberen StirnflÃĪche der SchutztÞr 1 befestigt ist, in diesem Fall mittels zweier Schrauben 7. Zudem ist das Anschlagblech 9 bei dieser AusfÞhrungsform als Winkelblech 9 ausgebildet und der Bimetall-Streifen 3, 4 mit einer Öffnung 14 versehen, derart, dass bei einem erwÃĪrmungsbedingten Sichnachobenbiegen des Bimetall-Streifens 3, 4 der freie Schenkel des abgewinkelten Anschlagblechs 9 in die Öffnung 14 eintritt und sich hierdurch der Formschluss in TÞrÃķffnungsrichtung O ergibt.Figures 5a and 5b show an arrangement similar to the arrangement shown in Figures 4a and 4b, which, however, differs from the latter in that the bimetallic strip 3, 4 is not transverse to the door opening direction O but along this on the upper end face of the In addition, the stop plate 9 is formed in this embodiment as an angle plate 9 and the bimetallic strip 3, 4 provided with an opening 14, such that in a heating-related Sichnachobenbiegen the bimetallic strip 3, 4, the free leg of the angled stopper plate 9 enters the opening 14 and thereby the positive connection in the door opening direction O results.

Die Figuren 6a und 6b zeigen eine Anordnung ÃĪhnlich der in den Figuren 5a und 5b gezeigten Anordnung, welche sich jedoch von der letztgenannten dadurch unterscheidet, dass der Bimetall-Streifen 3, 4 keine Öffnung aufweist und nicht auf der Bandseite der oberen StirnflÃĪche der SchutztÞr 1 befestigt ist, sondern auf der Gegenbandseite der oberen StirnflÃĪche, so dass er sich bei starker ErwÃĪrmung auf der Bandseite nach oben biegt, wo er dann einen Formschluss in TÞrÃķffnungsrichtung O mit einer Profilnase 12 des oberen Rahmenprofils der TÞrzarge 2 bildet. Diese Situation ist in Fig. 6a dargestellt.Figures 6a and 6b show an arrangement similar to the arrangement shown in Figures 5a and 5b, which, however, differs from the latter in that the bimetallic strip 3, 4 has no opening and not on the band side of the upper end surface of the protective door first is fixed, but on the opposite band side of the upper end face, so that it bends upwards on strong side on the hinge side, where it then forms a positive fit in the door opening direction O with a profile nose 12 of the upper frame profile of the door frame 2. This situation is shown in Fig. 6a.

Fig. 7 zeigt eine Ansicht wie Fig. 2a durch eine weitere erfindungsgemÃĪsse Anordnung, welche sich von den zuvor gezeigten grundsÃĪtzlich dadurch unterscheidet, dass hier eine erfindungsgemÃĪsse Verriegelungseinheit 13 mittels mehrerer Schrauben 7 auf der gegenbandseitigen AussenflÃĪche der SchutztÞre 1 angeordnet ist, welche die Verriegelungsfunktion dadurch wahrnimmt, dass aus ihr bei starker ErwÃĪrmung ein Riegelbolzen 3 hervortritt, welcher dann einen Formschluss in TÞrÃķffnungsrichtung O mit der AussenflÃĪche des oberen Rahmenprofils der TÞrzarge 2 bildet. Wie zu erkennen ist, ist der Riegelbolzen 3 in einer FÞhrungshÞlse 10 im GehÃĪuse 15 gelagert und wird, wie bereits bei der Anordnungen gemÃĪss den Figuren 2a, 2b und 3a, 3b beschrieben, von einer Bimetall-Lasche 4 betÃĪtigt, welche hier jedoch an ihrem BetÃĪtigungsende einen seitlich offenen Schlitz zur Koppelung mit dem Riegelbolzen 3 aufweist. Das andere Ende der Bimetall-Lasche 4 ist fest mit dem GehÃĪuse 15 verbunden.Fig. 7 shows a view like Fig. 2a by another inventive arrangement, which differs fundamentally from the previously shown in that here a locking unit 13 according to the invention is arranged by means of several screws 7 on the gegenbandseitigen outer surface of the protective door 1, which thereby the locking function perceives that emerges from her with strong warming a locking bolt 3, which then forms a positive connection in the door opening direction O with the outer surface of the upper frame profile of the door frame 2. As can be seen, the locking bolt 3 is mounted in a guide sleeve 10 in the housing 15 and is how already described in the arrangements according to Figures 2a, 2b and 3a, 3b, actuated by a bimetallic flap 4, which here, however, at its operating end has a laterally open slot for coupling with the locking bolt 3. The other end of the bimetallic tab 4 is fixedly connected to the housing 15.

Auch wenn in den Figuren ausschliesslich Anordnungen gezeigt sind, welche im verriegelten Zustand einen relativ grossen TÞrflÞgelversatz zulassen, so sind auch Anordnungen vorgesehen, welche lediglich einen solchen Versatz von einigen wenigen Millimetern oder auch gar keinen TÞrflÞgelversatz zulassen. Auch sei darauf hingewiesen, dass die Erfindung nicht auf die Verwendung von bimetallbetÃĪtigten Verriegelungsorganen beschrÃĪnkt ist, sondern sÃĪmtliche BetÃĪtigungsmechanismen mitumfasst, welche auf einer WÃĪrmedehnung von Materialien infolge einer starken ErwÃĪrmung der Umgebung der SchutztÞr basieren. Zudem ist es auch vorgesehen, die Verriegelungsorgane 3 nicht, wie in den Figuren gezeigt, an der SchutztÞr 1 anzuordnen, sondern an der TÞrzarge 2, so dass diese bei ErwÃĪrmung einen Formschluss in TÞrÃķffnungsrichtung O mit der SchutztÞr 1 bzw. einem an dieser angeordneten Anschlagelement bewirken.Even if in the figures only arrangements are shown, which allow a relatively large door leaf offset in the locked state, so arrangements are provided which allow only such an offset of a few millimeters or even no door leaf offset. It should also be noted that the invention is not limited to the use of bimetallic actuated locking members, but includes all actuation mechanisms based on thermal expansion of materials due to severe heating of the environment of the protective door. In addition, it is also envisaged not to arrange the locking members 3 on the protective door 1, as shown in the figures, but on the door frame 2 so that they form a positive locking in the door opening direction O with the protective door 1 or a stop element arranged on the latter when heated cause.
