Abstract

A hinge arrangement (2) for a switch cabinet starts from the use of a vertical structural element (1) having a front face (7) and of a door leaf (3) having a bent leg (10). A stationary hinge part to be mounted on the front face (7) of the vertical structural element (1) possesses a flatly curved foot part with end edges approximately similar to knife edges and a hinge arm for a hinge pin. The hinge arm (15) is received between legs (24) of a movable hinge part (14) which can be introduced into a perforation (21) in the region of the bent portion of the door leaf (3) and which is supported by means of edge webs (22). An orifice (33) in the foot part (16) allows a front fastening of the stationary hinge part (13) on the front face (7). The hinge arrangement permits a large opening angle and can be used in conjunction with sealing elements.

Description

Die Erfindung betrifft eine Scharnieranordnung für einen Schaltschrank mit folgenden Merkmalen:
ein zum Verschließen einer Türöffnung dienendes, am Rand mit mindestens einem abgekanteten Schenkel versehenen Türblatt;
ein vertikales Gerüstelement mit einer Frontfläche;
ein auf der Frontfläche mittels eines Fußteiles zu befestigendes feststehendes Scharnierteil;
ein an dem Türblatt nahe dem abgekanteten Schenkel zu befestigendes bewegbares Scharnierteil sowie
ein im wesentlichen zylindrischer Scharnierbolzen zum Einführen in fluchtende Öffnungen von Schenkeln des bewegbaren Scharnierteiles und zur Aufnahme in einem Scharnierarm des feststehenden Scharnierteiles. Eine Scharnieranordnung dieser Art ist beispielsweise durch die EP-A-0 274 549 bekannt geworden.The invention relates to a hinge arrangement for a control cabinet with the following features:
a door leaf serving to close a door opening and provided with at least one bent leg at the edge;
a vertical scaffold element with a front surface;
a fixed hinge part to be fastened on the front surface by means of a foot part;
a movable hinge part to be fastened to the door leaf near the folded leg and
an essentially cylindrical hinge pin for insertion into aligned openings of legs of the movable hinge part and for receiving in a hinge arm of the fixed hinge part. A hinge arrangement of this type is known, for example, from EP-A-0 274 549.

Von dem vorgesehenen Aufstellungsort eines Schaltschrankes oder einer aus mehreren Schaltschränken bestehenden Schaltanlage hängt es ab, ob geringere oder erhöhte Anforderungen an die Dichtigkeit der Türen gestellt werden. Es kann daher erforderlich sein, zwischen dem Türblatt und den Gerüstelementen, an denen das Türblatt im geschlossenen Zustand aufliegt, besondere Dichtungselemente in der Gestalt von gummieleastischen Streifen, Bändern, Schnüren oder ähnlichen Formen einzubringen. Sollen Dichtungsmittel dieser Art am ganzen Umfang des Türblattes gleichmäßig wirksam sein, so ist hierfür eine durchgehende Auflagefläche für ein Dichtungselement zwischen den Kanten des Türblattes und den die Türöffnung begrenzenden Gerüstelementen wesentlich. Liegt der feststehende Scharnierteil außerhalb der Abkantung des Türblattes, so treten keine Probleme auf, weil alle die Türöffnung begrenzenden Frontflächen für die Abdichtung zur Verfügung stehen. Dies erfordert jedoch bei unveränderter Gesamtbreite eine breitere Frontfläche des Gerüstelementes und verändert dementsprechend den zur Montage zur Verfügung stehenden Querschnitt.It depends on the intended installation location of a control cabinet or a switchgear consisting of several control cabinets whether lower or higher requirements are imposed on the tightness of the doors. It may therefore be necessary to insert special sealing elements in the form of rubber-elastic strips, bands, cords or similar shapes between the door leaf and the frame elements on which the door leaf rests in the closed state. If sealing means of this type are to be uniformly effective over the entire circumference of the door leaf, a continuous contact surface for a sealing element between the edges of the door leaf and the scaffolding elements delimiting the door opening is essential for this. If the fixed hinge part is outside the fold of the door leaf, no problems arise because all the front surfaces delimiting the door opening are available for the sealing. However, this requires unchanged Overall width a wider front surface of the scaffold element and accordingly changes the cross section available for assembly.

Wird demgegenüber eine Lage der Scharnierachse an der Innenseite des Türblattes nahe einer Abkantung gewählt, so wird ein bis 180° reichender Öffnungswinkel bei minimaler zusätzlicher Ausladung erzielt. Allerdings unterbrechen nun die feststehenden Scharnierteile den durchgehenden geradlinigen Weg des Dichtungselementes auf der Frontfläche des scharnierseitigen vertikalen Gerüstelementes.If, on the other hand, a position of the hinge axis on the inside of the door leaf near a bevel is selected, an opening angle of up to 180 ° is achieved with minimal additional projection. However, the fixed hinge parts now interrupt the continuous straight path of the sealing element on the front surface of the hinge-side vertical frame element.

Um eine gute Abdichtung am ganzen Umfang des Türblattes bei einfacher Anbringung des Dichtungselementes zu erreichen, ist es bereits bekannt, eine Scharnieranordnung mit einer an der Innenseite des Gerüstes des Schaltschrankes gelegenen Scharnierachse zu wählen (DE-A-1 690 079). Diese Anordnung weist ferner einen Scharnierarm mit einem zusätzlichen an der Innenseite des Türblattes gelegenen Gelenk und einen einstellbaren Anschlag auf, um beim Schließen der Tür einen gleichmäßigen Andruck zwischen Türblatt und Dichtungselementen zu bewirken. Der an der Innenseite des Gerüstes gelagerte Scharnierarm beansprucht jedoch einen nicht unbeträchtlichen Raum an der Innenseite des Gerüstes. Es besteht demgegenüber das Interesse, den an die Türöffnung angrenzenden inneren Bereich vollkommen frei zu halten, damit Verdrahtungen und Einbauten an jeder gewünschten Stelle angebracht werden können.In order to achieve a good seal on the entire circumference of the door leaf with simple attachment of the sealing element, it is already known to choose a hinge arrangement with a hinge axis located on the inside of the frame of the control cabinet (DE-A-1 690 079). This arrangement also has a hinge arm with an additional joint located on the inside of the door leaf and an adjustable stop in order to bring about a uniform pressure between the door leaf and sealing elements when the door is closed. However, the hinge arm mounted on the inside of the scaffold takes up a not inconsiderable space on the inside of the scaffold. In contrast, there is interest in keeping the inner area adjacent to the door opening completely free, so that wiring and installations can be attached at any desired location.

Der Erfindung liegt die Aufgabe zugrunde, eine raumsparende und einfach montierbare Scharnieranordnung zu schaffen, die einen großen Öffnungswinkel des Türblattes ermöglicht und ohne Schwierigkeit in Verbindung mit einem Dichtungselement einsetzbar ist.The invention has for its object to provide a space-saving and easy to assemble hinge arrangement that allows a large opening angle of the door leaf and can be used without difficulty in connection with a sealing element.

Diese Aufgabe wird gemäß der Erfindung durch folgende Merkmale gelöst:
Der Fußteil des feststehenden Scharnierteiles ist flach gewölbt und in der Längsrichtung der Frontfläche des vertikalen Gerüstelementes an beiden Enden von je einer schneidenförmigen Endkante begrenzt, derart, daß ein zwischen dem abgekanteten Schenkel und der Frontfläche befindliches Dichtungselement an den Übergängen von der Frontfläche zu dem Fußteil und auf dem Fußteil dicht anliegend verläuft, und in dem Fußteil ist wenigstens eine von vorn zugängliche Öffnung für den versenkten Eingriff eines Befestigungselementes angeordnet.This object is achieved according to the invention by the following features:
The foot part of the fixed hinge part is curved flat and limited in the longitudinal direction of the front surface of the vertical scaffolding element at both ends by a cutting edge end edge, such that a sealing element located between the bent leg and the front surface at the transitions from the front surface to the foot part and runs close to the foot part, and in the foot part there is at least one opening accessible from the front for the recessed engagement of a fastening element.

Die frontseitig zugängliche Öffnung bietet zunächst die Möglichkeit, den feststehenden Scharnierteil auf der Frontseite eines Gerüstelementes mit Hilfe einer Schraube bequem zu befestigen. Im Unterschied hierzu ist bei der eingangs erwähnten bekannten Scharnieranordnung eine Befestigung von der Innenseite des Gerüstelementes her vorgesehen. Dies beschränkt die Wahl der Profilform des Gerüstelementes. Die flach gewölbte Form des Fußteiles ist für die Befestigung günstig und gestattet es gleichzeitig, ein Dichtungselement ohne Knick oder Abwinklung auch im Scharnierbereich anzuwenden.The opening accessible from the front offers the option of conveniently attaching the fixed hinge part to the front of a scaffold element with the help of a screw. In contrast to this, in the known hinge arrangement mentioned at the outset, attachment is provided from the inside of the scaffold element. This limits the choice of the profile shape of the scaffold element. The flat, arched shape of the foot section is favorable for fastening and also allows a sealing element to be used in the hinge area without kinking or bending.

Um das Zusammenwirken zwischen dem Türblatt und dem Dichtungselement im Bereich der Scharnierachse zu verbessern, kann die Abkantung des Türblattes derart ausgeführt sein, daß im geschlossenen Zustand der Tür der auf die Frontseite des Gerüstelementes weisende Schenkel gegenüber der Außenkante des Türblattes nach innen versetzt ist. Hierdurch läßt sich erreichen, daß die Abkantung im geschlossenen Zustand über den gewölbten Fußteil verläuft.In order to improve the interaction between the door leaf and the sealing element in the area of the hinge axis, the folding of the door leaf can be carried out such that in the closed state of the door the leg pointing to the front of the scaffolding element is offset inwards relative to the outer edge of the door leaf. In this way it can be achieved that the fold runs in the closed state over the arched foot part.

Wird nach einer Weiterbildung der Erfindung der zur Frontseite des Gerüstelementes weisende Schenkel des Türblattes im Bereich des Fußteiles des feststehenden Scharnierteiles mit einer dem Fußteil angepaßten abgerundeten Kontur versehen, so sind auch Dichtungselemente mit verhältnismäßig geringer Dicke verwendbar, die im Bereich der Scharniere keiner erhöhten Beanspruchung ausgesetzt sind.According to a development of the invention, the front the leg of the scaffolding element of the door leaf in the area of the foot part of the fixed hinge part is provided with a rounded contour adapted to the foot part, so sealing elements with a relatively small thickness can be used, which are not exposed to increased stress in the area of the hinges.

Eine ähnlich einfache Montage wie für das Fußteil kann nach einer weiteren Ausgestaltung der Erfindung auch für den bewegbaren Scharnierteil dadurch erzielt werden, daß das Türblatt im Bereich der Abkantung eine Durchbrechung zur Aufnahme des bewegbaren Scharnierteiles aufweist und daß der bewegbare Scharnierteil mit Randstegen zur wenigstens abschnittsweisen Auflage am Rand der Durchbrechung aufweist.A similarly simple assembly as for the foot part can also be achieved for the movable hinge part according to a further embodiment of the invention in that the door leaf has an opening in the area of the fold for receiving the movable hinge part and in that the movable hinge part with edge webs for at least section-wise support has at the edge of the opening.

Die Erfindung wird im folgenden anhand der in den Figuren dargestellten Ausführungsbeispiele näher erläutert.The invention is explained in more detail below with reference to the exemplary embodiments shown in the figures.

In den Figuren 1 bis 4 ist ein erstes Ausführungsbeispiel der Erfindung dargestellt. Dabei zeigt die Figur 1 in einer perspektivischen Darstellung einen Abschnitt eines vertikalen Gerüstelementes und eines Türblattes im geschlossenen Zustand.A first exemplary embodiment of the invention is shown in FIGS. 1 to 4. 1 shows a perspective view of a section of a vertical scaffold element and a door leaf in the closed state.

In der Figur 2 ist das Türblatt in einer Darstellung entsprechend der Figur 1 in geöffnetem Zustand gezeigt.In Figure 2, the door leaf is shown in a representation corresponding to Figure 1 in the open state.

Die Figur 3 zeigt in einer auseinandergezogenen Darstellung einen Abschnitt eines Türblattes und eines bewegbaren Scharnierteiles.FIG. 3 shows an exploded view of a section of a door leaf and a movable hinge part.

In der Figur 4 ist gleichfalls pespektivisch auseinandergezogen ein Abschnitt eines vertikalen Gerüstelementes sowie ein feststehender und ein bewegbarer Scharnierteil dargestellt.FIG. 4 also shows a section of a vertical scaffold element, as well as a fixed and a movable hinge part, in a perspective view.

Die Figur 5 zeigt in einer perspektivisch auseinandergezogenen Darstellung einen Abschnitt eines Türblattes und einen bewegbaren Scharnierteil eines abgewandelten Ausführungsbeispieles.FIG. 5 shows a section of a door leaf and a movable part in a perspective exploded view Hinge part of a modified embodiment.

Die Figuren 6 und 7 betreffen ein weiteres Ausführungsbeispiel der Erfindung. In der Figur 6 in einer der Figur 2 entsprechenden Darstellung ein Abschnitt eines Türblattes und eines vertikalen Gerüstelementes mit einer Scharnieranordnung gezeigt, wobei eine Abkantung des Türblattes eine abgerundete Ausnehmung aufweist.Figures 6 and 7 relate to another embodiment of the invention. FIG. 6 shows, in a representation corresponding to FIG. 2, a section of a door leaf and a vertical scaffold element with a hinge arrangement, with a bevel of the door leaf having a rounded recess.

Die Figur 7 zeigt in einer perspektivisch auseinandergezogenen Darstellung einen Abschnitt eines Türblattes und einen zugehörigen bewegbaren Scharnierteil.FIG. 7 shows a section of a door leaf and an associated movable hinge part in a perspective exploded view.

In der Figur 1 ist ein Abschnitt eines vertikalen Gerüstelementes 1 gezeigt, an dem eine Scharnieranordnung 2 für ein gleichfalls abgebrochen und verkürzt gezeigtes Türblatt 3 angebracht ist. Ein weiteres vertikales Gerüstelement 4 begrenzt zusammen mit einem nicht gezeigten oberen Querholm und einem entsprechenden unteren Querholm eine Türöffnung 5. Das Türblatt 3 ist an seinem Umfang in Richtung auf die Gerüstelemente abgekantet. Während die dem Gerüstelement 4 zugeordnete Ankantung 6 einfach rechtwinklig ausgeführt ist, befindet sich am gegenüberliegenden, scharnierseitigen Rand des Türblattes 3 ein gleichfalls rechtwinklig zur Frontfläche 7 des Gerüstelementes 1 stehenden Schenkel 10, der durch einen Knick 11 gegenüber der Außenkante 12 des Türblattes 3 nach innen versetzt ist. Die Scharnieranordnung 2 umfaßt einen feststehenden Scharnierteil 13 sowie einen bewegbaren Scharnierteil 14. Beide Scharnierteile werden im folgenden näher erläutert. Je nach Größe und Gewicht des Türblatts 3 können zwei oder mehrere Scharnieranordnungen 2 vorgesehen sein.FIG. 1 shows a section of a vertical scaffold element 1, to which a hinge arrangement 2 for a door leaf 3, which is likewise broken off and shortened, is attached. Another vertical scaffold element 4, together with an upper cross member (not shown) and a corresponding lower cross member, delimits a door opening 5. The door leaf 3 is folded on its circumference in the direction of the scaffold elements. While the edging 6 assigned to the scaffolding element 4 is of a simple right-angled design, there is a leg 10 at the opposite, hinge-side edge of the door leaf 3 which is also perpendicular to the front surface 7 of the scaffolding element 1 and which is bent inwards by a bend 11 relative to the outer edge 12 of the door leaf 3 is offset. The hinge arrangement 2 comprises a fixed hinge part 13 and a movable hinge part 14. Both hinge parts are explained in more detail below. Depending on the size and weight of the door leaf 3, two or more hinge arrangements 2 can be provided.

Anhand der Figur 2, welche das Türblatt 3 in geöffnetem Zustand zeigt, ist zunächst ersichtlich, daß der feststehende Scharnierteil 13 einen Scharnierarm 15 und einen Fußteil 16 bestitzt. Der Fußteil 16 ist flach gewölbt ausgebildet und endet in der Längsrichtung der Frontfläche 7 gesehen, d. h. in der Darstellung gemäß der Figur 2 oben und unten, jeweils mit einer schneidenartigen Endkante 17 (Figur 4). Es ist nicht erforderlich, daß die Endkanten 17 eine messerartige Schärfe aufweisen. Erwünscht ist jedoch eine so geringe Materialdicke, daß sich ein Streifen eines Dichtungsmaterials auf der Frontfläche 7 derart verlegen läßt, daß am Übergang zwischen der Frontfläche 7 und dem Fußteil 16 kein nennenswerter Zwischenraum entsteht. Ein Dichtungsrahmen 18 ist in der Figur 2 angedeutet. Der Scharnierarm 15 zweigt seitlich von dem Fußteil 16 ab, so daß die Gesamtfläche des Fußteiles 16 zur Anbringung von Dichtungsmaterial zur Verfügung steht. Der bewegbare Scharnierteil 14 besitzt eine dem Scharnierarm 15 angepaßte Ausnehmung 20. Scharnierarm 15 und Ausnehmung 20 sind, wie aus der Figur 1 zu entnehmen ist, derart aneinander angepaßt, daß sich im geschlossenen Zustand eine im wesentlichen bündige Außenfläche ergibt.With reference to FIG. 2, which shows the door leaf 3 in the open state, it can first be seen that the fixed hinge part 13 has a hinge arm 15 and a foot part 16. The foot part 16 is flatly arched and ends in the Seen in the longitudinal direction of the front surface 7, ie in the illustration according to FIG. 2 above and below, each with a cutting-like end edge 17 (FIG. 4). It is not necessary that the end edges 17 have a knife-like sharpness. However, such a small material thickness is desirable that a strip of sealing material can be laid on the front surface 7 in such a way that at the transition between the front surface 7 and the foot part 16 there is no significant space. A sealing frame 18 is indicated in Figure 2. The hinge arm 15 branches off laterally from the foot part 16, so that the total area of the foot part 16 is available for the application of sealing material. The movable hinge part 14 has a recess 20 which is adapted to the hinge arm 15. As can be seen from FIG. 1, the hinge arm 15 and recess 20 are adapted to one another in such a way that an essentially flush outer surface results in the closed state.

Das Türblatt 3 ist gemäß der Figur 3 mit einer Durchbrechung 21 versehen, die etwa am Übergang zwischen dem Schenkel 10 und dem Knick 11 beginnt und bis in den vorderen, ebenen Teil des Türblattes hineinreicht. Der bewegbare Scharnierteil 14 ist derart ausgebildet, daß er sich von außen in die Durchbrechung 21 einführen läßt und dabei Randstege 22 am Rand der Durchbrechung 21 zur Anlage auf dem Türblatt 3 gelangen. Durch geeignete Befestigungselemente, die von der Innenseite der Abkantung der Tür in das Scharnierteil 14 eingreifen, ist daher eine zuverlässige Befestigung und Lagesicherung des Scharnierteiles 14 gewährleistet. Die Randstege 22 bilden somit nicht nur einen Anschlag beim Einführen des Scharnierteiles 14 in die Durchbrechung 21, sondern verbessern auch die Dichtigkeit gegen Staub und Wasser. In der Figur 3 sind ferner zwei Madenschrauben 23 zur Befestigung des Scharnierteiles 14 an dem Türblatt 3 gezeigt. Die Ausnehmung 20 in dem bewegbaren Scharnierteil 14 ist mittig angeordnet und bildet zwei Schenkel 24 mit je einer Öffnung 25 für einen zylindrischen Scharnierbolzen 26.According to FIG. 3, the door leaf 3 is provided with an opening 21 which begins approximately at the transition between the leg 10 and the bend 11 and extends into the front, flat part of the door leaf. The movable hinge part 14 is designed such that it can be inserted into the opening 21 from the outside and thereby edge webs 22 come to rest on the door leaf 3 at the edge of the opening 21. Suitable fastening elements which engage in the hinge part 14 from the inside of the folded edge of the door therefore ensure reliable fastening and securing of the position of the hinge part 14. The edge webs 22 thus not only form a stop when inserting the hinge part 14 into the opening 21, but also improve the tightness against dust and water. FIG. 3 also shows two grub screws 23 for fastening the hinge part 14 to the door leaf 3. The recess 20 in the movable hinge part 14 is arranged in the center and forms two legs 24, each with an opening 25 for a cylindrical hinge pin 26.

Wie die Figur 4 zeigt, besitzt der feststehende Scharnierteil 13 an seiner Rückseite zwei Zapfen 30, zu deren Aufnahme in der Frontseite 7 des Gerüstelementes 1 entsprechende Öffnungen 31 vorgesehen sind. Mittig zwischen den Öffnungen 31 ist eine weitere Öffnung 32 vorgesehen, die mit einer entsprechenden Öffnung 33 in dem Fußteil 16 des Scharnierteiles 13 fluchtet. Vorzugsweise kann die Öffnung 33 als Senkloch ausgebildet sein, um eine in der Figur 3 gezeigte Befestigungsschraube 34 ohne Überstand über die gewölbte Fläche des Fußteiles 16 einsetzen zu können. Durch die Zapfen 30 wird eine genaue Lagesicherung und eine Kraftübertragung zwischen dem Scharnierteil 13 und dem Gerüstelement 1 erzielt. An seiner Innenseite ist der bewegbare Scharnierteil 14 mit einer Nase 19 versehen, die zum Eingreifen in eine entsprechende Öffnung 8 im Schenkel 10 des Türblattes 3 vorgesehen ist.As FIG. 4 shows, the fixed hinge part 13 has two pins 30 on its rear side, corresponding openings 31 being provided in the front side 7 of the scaffold element 1 for receiving them. A further opening 32 is provided in the center between the openings 31 and is aligned with a corresponding opening 33 in the foot part 16 of the hinge part 13. The opening 33 can preferably be designed as a countersunk hole in order to be able to insert a fastening screw 34 shown in FIG. 3 without protruding over the curved surface of the foot part 16. The pin 30 ensures an exact positional securing and a power transmission between the hinge part 13 and the scaffold element 1. On its inside, the movable hinge part 14 is provided with a nose 19 which is provided for engaging in a corresponding opening 8 in the leg 10 of the door leaf 3.

Nach der Befestigung des Scharnierteiles 13 an dem Gerüstelement 1 und der Anbringung des Scharnierteiles 14 an dem Türblatt 3 (Figur 3 und 4) können beide Scharnierteile auf einfache Weise dadurch verbunden werden, daß das Türblatt 3 etwa in eine Stellung entsprechend der Figur 2 mit den Scharnierarmen 15 in Eingriff gebracht und dann der Scharnierbolzen 26 eingesteckt wird.After the hinge part 13 has been fastened to the scaffolding element 1 and the hinge part 14 has been attached to the door leaf 3 (FIGS. 3 and 4), both hinge parts can be connected in a simple manner in that the door leaf 3 is approximately in a position corresponding to FIG Hinge arms 15 are engaged and then the hinge pin 26 is inserted.

Eine abgewandelte Ausführungsform gemäß der Figur 5 weist ein im wesentlichen mit den vorstehend beschriebenen Teilen übereinstimmendes Türblatt 3 mit einer Durchbrechung 21, jedoch ein abweichend gestaltetes bewegbares Scharnierteil 35 auf. Dieses ist bei ansonsten mit dem bewegbaren Scharnierteil 14 übereinstimmender Gestaltung mit einem durchgehenden Kanal 36 versehen, der abgesehen von einem Längsschlitz 37 eine etwa zylindrische Gestalt aufweist. Zur Befestigung des Scharnierteiles 35 an dem Türblatt 3 wird das Scharnierteil zunächst in der schon beschriebenen Weise in die Durchbrechung 21 eingeführt. Der Kanal 36 befindet sich dann an der Innenseite der Abkantung des Türblattes 3, so daß ein Kerbstift 38 in den Kanal 36 eingedrückt werden kann. Türblatt 3 und Scharnierteil 35 sind dann fest miteinander verbunden, können jedoch im Bedarfsfall durch Herausschlagen der Kerbstifte 38 voneinander getrennt werden.A modified embodiment according to FIG. 5 has a door leaf 3 which essentially corresponds to the parts described above and has an opening 21, but a differently designed movable hinge part 35. This is otherwise provided with the movable hinge part 14 design with a continuous channel 36 which, apart from a longitudinal slot 37 has an approximately cylindrical shape. To fasten the hinge part 35 to the door leaf 3, the hinge part is first inserted into the opening 21 in the manner already described. The channel 36 is then on the inside of the fold of the door leaf 3, so that a grooved pin 38 in the Channel 36 can be pressed. Door leaf 3 and hinge part 35 are then firmly connected to one another, but can, if necessary, be separated from one another by knocking out the grooved pins 38.

In der Figur 6 ist in Verbindung mit einem vertikalen Gerüstelement 1 mit einer Frontfläche 7 und einem feststehenden Scharnierteil 13 etwa entsprechend der Figur 2 ein Türblatt 40 mit einer abgewandelten Gestalt der Abkantung gezeigt. Die Abkantung ist zweifach rechtwinklig ausgeführt, derart, daß ebenfalls ein im geschlossenen Zustand rechtwinklig zur Frontfläche 7 stehender und nach innen versetzter Schenkel 41 gebildet ist. In seinem im geschlossenen Zustand dem Fußteil 16 zugewandten Bereich ist der Schenkel 41 mit einer gekrümmten Ausnehmung 42 versehen. Hierdurch wird ein etwa paralleler Spalt zwischen dem Fußteil 16 und dem Schenkel 41 gebildet, der durch ein Dichtungselement ausgefüllt werden kann.In FIG. 6, in connection with a vertical scaffold element 1 with a front surface 7 and a fixed hinge part 13, approximately corresponding to FIG. 2, a door leaf 40 with a modified shape of the fold is shown. The fold is designed to be rectangular at two points, such that a leg 41, which is perpendicular to the front surface 7 and is offset inwards in the closed state, is also formed. In the region facing the foot part 16 in the closed state, the leg 41 is provided with a curved recess 42. As a result, an approximately parallel gap is formed between the foot part 16 and the leg 41, which can be filled by a sealing element.

Als Beispiel für eine Dichtung zeigt die Figur 6 eine Dichtungsschnur 48, die zwischen dem Schenkel 41 und einem an diesem Schenkel befestigten Haltesteg 49 angeordnet ist. Die Dichtungsschnur folgt dabei der Kontur der gekrümmten Ausnehmung 42 des Schenkels 41.As an example of a seal, FIG. 6 shows a sealing cord 48 which is arranged between the leg 41 and a retaining web 49 fastened to this leg. The sealing cord follows the contour of the curved recess 42 of the leg 41.

Aus der Figur 7 ist die an die veränderte Gestalt der Abkantung gemäß der Figur 6 angepaßte Form eines bewegbaren Scharnierteiles 43 zu entnehmen. Obere und untere Stege 44 dienen in der schon erwähnten Weise als Anschlag beim Einführen in eine an das Scharnierteil 43 angepaßte Durchbrechung 45. Ebenso dienen Madenschrauben 23 zur Verbindung von Türblatt 40 und Scharnierteil 43.FIG. 7 shows the shape of a movable hinge part 43 adapted to the changed shape of the fold according to FIG. 6. Upper and lower webs 44 serve in the manner already mentioned as a stop when inserted into an opening 45 adapted to the hinge part 43. Likewise, grub screws 23 serve to connect the door leaf 40 and the hinge part 43.

Die Figur 7 zeigt ferner einen krückstockartig abgekröpften Scharnierbolzen 46 an sich bekannter Art, der jedoch zusätzlich eine am unteren Ende den kreisförmigen Querschnitt erweiternden Zapfen 47 aufweist. Ferner ist eine etwa keglig zulaufende Spitze 50 vorgesehen. Zum Durchtritt des Vorsprunges 47 sind die Öffnungen 51 in dem Scharnierteil 43 mit einer entsprechenden Erweiterung 52 versehen. Ebenso ist die Öffnung 53 des Scharnierarmes 15 mit einer Erweiterung 54 versehen. Diese Gestaltung erlaubt es, den Scharnierbolzen 46 nach dem Einführungen in die Öffnungen 51 und 53 durch eine Drehung zu verriegeln. Das Türblatt 40 ist daher im Bedarfsfall von den feststehenden Scharnierteilen 13 auf einfache Weise zu trennen, und zwar aufgrund der gewählten Stellung der Erweiterung 54 nur bei einem Öffnungswinkel von etwa 90°.FIG. 7 also shows a hinge pin 46 which is cranked like a crutch stick, but which additionally has a pin 47 which widens the circular cross section at the lower end. There is also an approximately tapered one Tip 50 provided. The openings 51 in the hinge part 43 are provided with a corresponding extension 52 for the passage of the projection 47. The opening 53 of the hinge arm 15 is also provided with an extension 54. This design allows the hinge pin 46 to be locked by rotation after insertion into the openings 51 and 53. If necessary, the door leaf 40 can therefore be separated from the fixed hinge parts 13 in a simple manner, specifically because of the selected position of the extension 54 only at an opening angle of approximately 90 °.
