Abstract

Between the door-frame (8) and the door jamb (5) is a spring element (4) which is twisted when the front door-attachment (1) is opened and which automatically closes when the door is left, as a result of the energy accumulated in the spring element. The spring element is in the form of a torque rod with a first end section joined to the frame of the attached-door, and a second end section joined to the door-jamb. At least the fitting (2) on the attached-door slides along the vertical frame profile (8) and is detachably fixable.

Description

Die Erfindung betrifft eine Vorsatztür mit einem Rahmen mit einer darin angebrachten Füllung, der mittels mehrerer Scharniere an einem Türstock oder -rahmen drehbar angebracht oder anbringbar ist.The invention relates to a front door with a frame with an attached therein Filling, which by means of several hinges on a door frame or -frame is rotatably attached or attachable.

Solche Befestigungssysteme sind bekannt und werden beispielsweise bei Vorsatztüren in Form leichter Insektenschutzgitter eingesetzt. Als Füllung wird ein Fiberglasgewebe oder eine Gewebebespannung verwendet, um das Eindringen von Insekten in das Hausinnere zu verhindern. Derartige Vorsatztüren werden üblicherweise außenseitig an dem Türstock oder Türrahmen angebracht und ermöglichen die problemlose Öffnung der Haustür nach innen. Gleichzeitig schützt die außenseitig angebrachte Vorsatztür vor einfliegenden Insekten.Such fastening systems are known and are used, for example, in front doors used in the form of light insect screens. A fiberglass fabric is used as the filling or a fabric covering used to penetrate To prevent insects from entering the house. Such front doors are common attached to the outside of the door frame or door frame and allow the problem-free opening of the front door to the inside. At the same time protects the outside front door against flying insects.

Wenn man durch die Tür hindurch gehen will, kann der außenseitig angebrachte Rahmen aufgeschwenkt werden. Zu diesem Zweck weist der Rahmen an einer Längsseite mehrere Scharniere auf, die gleichzeitig zur Befestigung des Rahmens an dem Tür- oder Fensterstock dienen. Nach dem Hindurchgehen durch die Tür kann diese wieder geschlossen werden. Es hat sich in der Praxis gezeigt, dass von Kindern das Schließen der Tür häufig vergessen wird, so dass die Schutzfunktion vor einfliegenden Insekten nicht gegeben ist. Es kann auch der Fall eintreten, dass die Tür zwar angelehnt wird, jedoch nicht vollständig an dem Türstock oder -rahmen anliegt, so dass ein schmaler Öffnungsspalt bleibt, der es Insekten ermöglicht, in das Haus zu gelangen.If you want to go through the door, the one on the outside can Frame can be swung open. For this purpose, the frame points to one On the long side there are several hinges that are used to fasten the frame serve on the door or window frame. After going through the door can be closed again. It has been shown in practice that children often forget to close the door, so the protective function against insects. It can also happen that the door is ajar, but not completely on the door frame or frame rests so that a narrow opening gap remains that it insects allows to get into the house.

Der Erfindung liegt damit das Problem zugrunde, eine Vorsatztür der eingangs genannten Art anzugeben, die die genannten Nachteile vermeidet und insbesondere ein sicheres Schließen der Tür gewährleistet.The invention is therefore based on the problem of a front door at the beginning specified type that avoids the disadvantages mentioned and in particular ensures that the door closes securely.

Zur Lösung dieses Problems ist bei der erfindungsgemäßen Vorsatztür vorgesehen, dass zwischen dem Rahmen und dem Türstock oder -rahmen wenigstens ein Federelement angebracht oder anbringbar ist, das beim Öffnen der Vorsatztür tordiert wird und bei losgelassener Tür durch die Wirkung der in dem Federelement gespeicherten Energie die Vorsatztür selbsttätig schließt. Auf diese Weise wird ein vollkommen automatisches Schließen der Vorsatztür erzielt, auch wenn der Benutzer vergißt, die Tür zu schließen.To solve this problem, it is provided in the front door according to the invention that that between the frame and the door frame or frame at least a spring element is attached or attachable that when opening the front door is twisted and with the door released by the action of in the spring element stored energy closes the front door automatically. In this way a completely automatic closing of the front door is achieved, even if the user forgets to close the door.

Es ist besonders zweckmäßig, wenn das Federelement als Torsionsstab ausgebildet und mit seinem ersten Endabschnitt drehfest mit dem Rahmen der Vorsatztür und mit seinem zweiten Endabschnitt drehfest mit dem Türstock oder -rahmen verbunden bzw. verbindbar ist. Durch die Verwendung eines Torsionsstabs lässt sich ein besonders platzsparender Aufbau schaffen. Der Torsionsstab wird in der Nähe der Drehachse der Vorsatztür angebracht, so dass die Längsachse des Torsionsstabs im Wesentlichen parallel zur Drehachse der Vorsatztür angeordnet ist. Dadurch ergibt sich der Vorteil eines sehr geringen Platzbedarfs und einer geringen Einbautiefe. Dieses Merkmal ist besonders wichtig, da derartige Türen sehr häufig auf der Außenseite durch ein Rollo verschließbar sind. Die Vorsatztür mitsamt dem Torsionsstab muß also besonders platzsparend aufgebaut sein, um das Schließen eines Rollos oder einer Jalousie zu ermöglichen. Dementsprechend wird bei der erfindungsgemäßen Vorsatztür die Drehbewegung der Vorsatztür in eine Torsionsbewegung des Torsionsstabs umgewandelt. Im Gegensatz zu bekannten Türschließern wird bei der erfindungsgemäßen Vorsatztür die Einbautiefe nicht erhöht.It is particularly expedient if the spring element is designed as a torsion bar and with its first end section rotatably with the frame of the front door and with its second end section rotatably with the door frame or frame is connected or connectable. By using a torsion bar create a particularly space-saving structure. The torsion bar is in the Attached near the axis of rotation of the front door so that the longitudinal axis of the torsion bar is arranged essentially parallel to the axis of rotation of the front door. This has the advantage of a very small space requirement and a small one Installation depth. This feature is particularly important because such doors are very can often be closed on the outside by a roller blind. The front door together the torsion bar must therefore be particularly space-saving to the Allow closing of a blind or blind. Accordingly the rotary movement of the front door in the front door according to the invention a torsional movement of the torsion bar is converted. In contrast to known ones Door closers in the front door according to the invention are the installation depth not increased.

Zweckmäßig weist der Torsionsstab zumindest außerhalb seiner Endabschnitte einen runden Querschnitt auf. Die Verwendung runder Stäbe bietet den Vorteil, dass genormte Halbzeuge verwendet werden können, die entsprechend kostengünstig sind.The torsion bar expediently has at least outside its end sections a round cross-section. The use of round rods offers the advantage that standardized semi-finished products can be used that are correspondingly inexpensive are.

Ein störungsfreier Betrieb und eine besonders sichere Funktion werden erzielt, wenn an der Vorsatztür und dem Türstock oder -rahmen ein jeweils einen Endabschnitt des Federelements bzw. des Torsionsstabs aufnehmender Aufnahmebeschlag angeordnet ist. Dieser Aufnahmebeschlag kann so ausgebildet sein, dass das Federelement, bzw. der Torsionsstab in den Aufnahmebeschlag einsteckbar ist. Die Montage beschränkt sich dadurch auf die Befestigung der beiden Aufnahmebeschläge an dem Türstock oder -rahmen sowie an der Vorsatztür. Die erfindungsgemäße Vorsatztür ist besonders einfach montierbar, wenn zumindest der an der Vorsatztür angeordnete Aufnahmebeschlag entlang des vertikalen Rahmenprofils verschiebbar und lösbar befestigbar ist. Für diesen Zweck eignen sich Vorsatztüren, insbesondere bei denen zumindest das in der Nähe der Drehachse angeordnete vertikale Rahmenprofil der Vorsatztür eine ein- oder beidseitig hinterschnittene Nut aufweist, in die ein entsprechend gegengleich ausgebildetes Nutstück des Aufnahmebeschlags einsetzbar und mittels eines Befestigungsmittels klemmbar befestigbar ist. Ein derartiges Befestigungssystem ist beispielsweise aus der nachveröffentlichten Patentanmeldung DE 199 61 980.8 bekannt. Der zweite, an dem Türstock oder -rahmen angeordnete Aufnahmebeschlag wird ortsfest befestigt, beispielsweise mit dem Rahmen verschraubt.Trouble-free operation and a particularly safe function are achieved if there is an end section on the front door and the door frame or frame of the spring element or the torsion bar receiving receiving fitting is arranged. This receiving fitting can be designed such that the spring element or the torsion bar can be inserted into the receiving fitting is. The assembly is limited to the attachment of the two mounting brackets on the door frame or frame as well as on the front door. The invention Front door is particularly easy to install if at least the mounting fitting arranged on the front door along the vertical frame profile is slidably and releasably attachable. Are suitable for this purpose Front doors, especially those at least close to the axis of rotation arranged vertical frame profile of the front door an undercut on one or both sides Has groove, in which a correspondingly oppositely designed groove piece the fitting can be used and by means of a fastener can be clamped fastened. Such a fastening system is, for example known from the subsequently published patent application DE 199 61 980.8. The second receiving fitting arranged on the door frame or frame fixed, for example screwed to the frame.

In einer Weiterbildung der Erfindung ist vorgesehen, dass an jedem Endabschnitt des Torsionsstabs zwei zueinander parallele Flächen durch Umformen ausgebildet sind, die in entsprechend gegengleich geformte Einstecköffnungen der Aufnahmebeschläge einsteckbar sind. Dieser Umformprozess ist erforderlich, damit der Torsionsstab ein Drehmoment übertragen kann. Die beiden Parallelflächen sind beispielhaft zu verstehen, die Erfindung ist jedoch nicht darauf beschränkt. Es sind weitere Modifikationen denkbar, der Torsionsstab kann z. B. an seinen Enden auch quadratisch oder sternförmig ausgebildet sein und in entsprechend passende Aufnahmebeschläge einsteckbar sein. Die Verwendung zweier zueinander paralleler Flächen bietet zusätzlich den Vorteil der leichten Herstellbarkeit.In a development of the invention it is provided that at each end section of the torsion bar two mutually parallel surfaces formed by reshaping are in correspondingly oppositely shaped insertion openings of the receiving fittings are insertable. This forming process is necessary so the torsion bar can transmit a torque. The two parallel surfaces are to be understood as examples, but the invention is not restricted to them. It further modifications are conceivable, the torsion bar can e.g. B. at its ends also be square or star-shaped and fit accordingly Receptacle fittings can be inserted. The use of two parallel to each other Surfaces also offers the advantage of being easy to manufacture.

Mit einer derartigen erfindungsgemäßen Vorsatztür wird bereits ein zuverlässiges Schließen ermöglicht. Der Torsionsstab wird beim Öffnen der Tür tordiert und dreht sich anschließend bei losgelassener Tür in seine Ausgangslage zurück. Aufgrund von Reibungsverlusten in den Scharnieren und durch die Materialdämpfung kann jedoch der Fall eintreten, dass die Vorsatztür nach dem Ende der Schließbewegung noch nicht vollständig geschlossen ist. Vorzugsweise ist der Torsionsstab daher unter einer Vorspannung montierbar. Bei der Montage wird dem Torsionsstab ein Moment eingeprägt, so dass auch bei vollständig geschlossener Tür zumindest eine kleines Restmoment auf die Vorsatztür ausgeübt wird, das diese in der Ruhestellung hält. With such a front door according to the invention is already a reliable Closing enables. The torsion bar is twisted when the door is opened and then turns back to its original position with the door released. by virtue of of friction losses in the hinges and due to the material damping However, it can happen that the front door after the end of the closing movement is not yet fully closed. Preferably, the torsion bar therefore mountable under a preload. When assembling the torsion bar a moment impressed so that even when the door is completely closed at least a small residual moment is exerted on the front door that this in which holds at rest.

Daher werden Vorsatztüren bevorzugt, bei denen die parallelen Flächen des ersten Endabschnitts des Torsionsstabs gegenüber denen des zweiten Endabschnitts bezüglich der Längsachse des Torsionsstabs um einen bestimmten Drehwinkel verdreht sind. Dieser Drehwinkel wird bei der Herstellung des Torsionsstabs bei dem Umformprozess berücksichtigt. Auf diese Weise kann der Torsionsstab bei geschlossener Tür so eingebaut werden, dass er ein schließendes Moment auf die Vorsatztür ausübt. Auf die Vorsatztür wirkt also ständig eine gewisse Vorspannung, die auch bei leichteren Windböen ein ungewolltes Öffnen der Vorsatztür verhindert.Therefore, front doors are preferred in which the parallel surfaces of the first End portion of the torsion bar opposite to that of the second end portion with respect to the longitudinal axis of the torsion bar by a certain angle of rotation are twisted. This angle of rotation is used in the manufacture of the torsion bar the forming process is taken into account. In this way, the torsion bar can closed door so that there is a closing moment on the door Front door exercises. A certain amount of pre-tension acts on the front door, which, even with lighter gusts of wind, opens the front door unintentionally prevented.

Besonders günstig sind Drehwinkel, die zwischen 5° und 20° betragen, vorzugsweise wird ein Drehwinkel von 10° gewählt. Die Angabe des Drehwinkels hängt selbstverständlich von dem Durchmesser und der Länge des Torsionsstabs ab. Die genannten Drehwinkel beziehen sich auf einen Durchmesser von 3 mm und eine Torsionsstablänge von 700 mm. Wird von diesen Parametern abgewichen, muss der Drehwinkel entsprechend angepasst werden. Die Federkonstante des Torsionsstabs kann durch seine Länge oder auch durch die Wahl eines anderen Querschnitts eingestellt werden. Bei größeren bzw. schwereren Vorsatztüren ist auch ein entsprechend stärkerer Torsionsstab zu verwenden.Rotation angles that are between 5 ° and 20 ° are particularly favorable, preferably a rotation angle of 10 ° is selected. The specification of the angle of rotation depends of course on the diameter and length of the torsion bar. The mentioned angles of rotation refer to a diameter of 3 mm and a torsion bar length of 700 mm. If you deviate from these parameters, the angle of rotation must be adjusted accordingly. The spring constant of the Torsion bar can be by its length or by choosing another one Cross-section can be set. For larger or heavier front doors also use a correspondingly stronger torsion bar.

Mit der erfindungsgemäßen Vorsatztür lässt sich ein maximaler Öffnungswinkel von 110° bis 130° erreichen, wobei ein Öffnungswinkel von 120° bevorzugt wird.A maximum opening angle can be achieved with the front door according to the invention from 110 ° to 130 °, with an opening angle of 120 ° being preferred.

Im Hinblick auf die Korrosionsbeständigkeit empfiehlt es sich, den Torsionsstab aus Stahl, insbesondere aus einem rostfreien Stahl herzustellen. Für die Aufnahmebeschläge kann eine Leichtmetall-Legierung verwendet werden.In terms of corrosion resistance, it is recommended to use the torsion bar to produce from steel, in particular from a stainless steel. For the fitting fittings a light metal alloy can be used.

Fig. 1 zeigt einen Schnitt durch eine Vorsatztür 1 im Bereich eines Aufnahmebeschlags 2. Die Vorsatztür 1 ist an einem Türrahmen 5 befestigt. Wie in Fig. 1 zu erkennen ist, liegt an dem Türrahmen 5 eine aufschwenkbare Tür 6 mit einer Verglasung 7 an, die in geschlossener Stellung gezeigt ist. Die Tür 6 und die Vorsatztür 1 sind an gegenüberliegenden Türpfosten befestigt, wobei die Tür 6, bei der es sich um eine Eingangstür eines Haus handeln kann, nach innen und die Vorsatztür 1 nach außen aufschwenkbar ist. Die Vorsatztür ist wie üblich mittels geeigneter Scharnierverbindungen, wie sie z. B. aus der Patentanmeldung 199 61 980.8, auf die ausdrücklich Bezug genommen wird, am Rahmen befestigt. Von der Vorsatztür 1 ist nur der für die Erfindung relevante Bereich dargestellt. Dabei handelt es sich um den Bereich des senkrechten Rahmenprofils 8 in der Nähe der Drehachse der Vorsatztür 1. Das Rahmenprofil 8 ist ein Hohlprofil, vorzugsweise aus Aluminium, das auf einer Seite eine Aufnahme 9 für ein Maschengewebe 10 aufweist. Das Maschengewebe 10, das ebenfalls nur in dem relevanten Ausschnitt dargestellt ist, erstreckt sich über die gesamte rechteckige Rahmenfläche, die von mehreren Rahmenprofilen 8 gebildet wird. Auf seiner Rückseite weist das Rahmenprofil 8 eine hinterschnittene Nut 11 auf, die sowohl zur Befestigung von nicht dargestellten Scharnieren als auch zur Befestigung des oberen Aufnahmebeschlags 2 und des unteren Aufnahmebeschlags 3 dient. Die nicht dargestellten Scharniere dienen zur Befestigung der Vorsatztür 1 an dem Türrahmen 5.Fig. 1 shows a section through a front door 1 in the region of a receiving fitting 2. The front door 1 is attached to a door frame 5. As in Fig. 1 too is recognizable, is a swing-open door 6 with glazing on the door frame 5 7, which is shown in the closed position. The door 6 and the front door 1 are attached to opposite door posts, the door 6, at which can be a front door of a house, inside and which Front door 1 can be swung open to the outside. The front door is, as usual, by means of suitable hinge connections, as z. B. from patent application 199 61st 980.8, to which express reference is made, is attached to the frame. Of the Front door 1 only shows the area relevant to the invention. Acting it is the area of the vertical frame profile 8 near the Axis of rotation of the front door 1. The frame profile 8 is a hollow profile, preferably Made of aluminum, which has a receptacle 9 for a mesh fabric 10 on one side having. The mesh 10, which is also only in the relevant section is shown, extends over the entire rectangular frame area by several frame profiles 8 is formed. The frame profile shows on its back 8 an undercut groove 11, which is not only for fastening shown hinges as well as for fastening the upper receiving fitting 2 and the lower mounting bracket 3 is used. The not shown Hinges are used to attach the front door 1 to the door frame 5.

Der obere Aufnahmebeschlag 2 weist eine augenförmige Ausnehmung 12 auf, in die ein Torsionsstab 4 eingesetzt ist. Der Torsionsstab 4 ist senkrecht zur Schnittebene angeordnet, so dass er nur im Querschnitt gezeigt ist. Das untere Ende des Torsionsstabs 4 ist in eine entsprechende Ausnehmung des unteren Aufnahmebeschlags 3 eingesetzt. Dieser Aufnahmebeschlag 3 ist über ein Verbindungsmittel, das in dem dargestellten Ausführungsbeispiel als Schraube 13 ausgebildet ist, mit dem Türrahmen 5 verschraubt. Die Aufnahmebeschläge 2, 3 können identisch sein, alternativ können sie sich aber auch hinsichtlich der Befestigung an dem Türrahmen bzw. an dem Rahmenprofil unterscheiden.The upper receiving fitting 2 has an eye-shaped recess 12, in which a torsion bar 4 is inserted. The torsion bar 4 is perpendicular to the cutting plane arranged so that it is only shown in cross section. The lower end of the Torsion bar 4 is in a corresponding recess of the lower receiving fitting 3 used. This receiving fitting 3 is via a connecting means, which is designed as a screw 13 in the illustrated embodiment, screwed to the door frame 5. The mounting fittings 2, 3 can be identical alternatively, they can also be in terms of attachment to the door frame or differentiate on the frame profile.

Fig. 2 zeigt eine perspektivische Teilansicht der Vorsatztür 1, aus der die Wirkungsweise des Torsionsstabs 4 hervorgeht. Von der Vorsatztür 1 ist lediglich ein Abschnitt des Rahmenprofils 8 dargestellt. Die nicht dargestellten Befestigungsscharniere für die Vorsatztür sind oberhalb und unterhalb des gezeigten Ausschnitts angeordnet. Die Drehachse der Befestigungsscharniere fällt in etwa mit der Längsachse des Torsionsstabs 4 zusammen. In dem dargestellten Ausführungsbeispiel ist die Vorsatztür 1 teilweise geöffnet. Wird die Vorsatztür 1 aus ihrer Ruhelage geschwenkt und damit geöffnet, dann wird der obere Aufnahmebeschlag 2, der an dem türseitigen Rahmenprofil 8 ortsfest angebracht ist, ebenfalls gedreht. Der Aufnahmebeschlag 2 ist andererseits mit dem oberen Ende des Torsionsstabs 4 verbunden. Das untere Ende des Torsionsstabs 4 ist ebenfalls drehfest in dem unteren Aufnahmebeschlag 3 eingesteckt, der ortsfest an dem Türrahmen 5 angebracht ist. Beim Öffnen der Vorsatztür 1 wird über den Aufnahmebeschlag 2 ein Moment in den Torsionsstab 4 eingeleitet. Es handelt sich also um die Torsion eines einseitig eingespannten Stabes. Dementsprechend führt das Öffnen der Vorsatztür 1 zu einer Torsion des Torsionsstabs 4. Diese Torsion liegt allerdings im linearelastischen Bereich, so dass die Torsion abgesehen von Reibungseinflüssen vollkommen reversibel ist. Wird nun die geöffnete Vorsatztür 1 in der in Fig. 2 dargestellten Lage losgelassen, übt der Torsionsstab 4 ein rückstellendes Moment auf die drehbewegliche Vorsatztür 1 aus. Dementsprechend kommt es zu einer Umkehr der Drehbewegung und die Vorsatztür 1 schließt selbsttätig, bis sie ihre Ausgangsposition erreicht hat.Fig. 2 shows a partial perspective view of the front door 1, from which the mode of operation of the torsion bar 4 emerges. There is only one of the front door 1 Section of the frame profile 8 shown. The fastening hinges, not shown for the front door are above and below the cutout shown arranged. The axis of rotation of the fastening hinges coincides approximately the longitudinal axis of the torsion bar 4 together. In the illustrated embodiment the front door 1 is partially open. If the front door 1 from her Rest position pivoted and thus opened, then the upper mounting bracket 2, which is fixed to the door-side frame profile 8, also turned. The receiving fitting 2 is on the other hand with the upper end of the torsion bar 4 connected. The lower end of the torsion bar 4 is also non-rotatable inserted in the lower receiving fitting 3, the stationary on the door frame 5 is attached. When opening the front door 1 is on the mounting bracket 2 initiated a moment in the torsion bar 4. So it's about the torsion of a bar clamped on one side. Accordingly, that leads Opening the front door 1 to a torsion of the torsion bar 4. This torsion lies however, in the linear-elastic range, so that the torsion apart from the effects of friction is completely reversible. Now the open front door 1 in released from the position shown in Fig. 2, the torsion bar 4 exercises a restoring Moment on the rotating front door 1. Accordingly there is a reversal of the rotary movement and the front door 1 closes automatically until it has reached its starting position.

Fig. 3 zeigt einen horizontalen Schnitt durch den Aufnahmebeschlag 2 für den Torsionsstab 4. Es handelt sich dabei um den mit dem Rahmenprofil 8 verbundenen Aufnahmebeschlag. Dieser weist ein L-förmiges Profil auf, an einem Ende ist die augenförmige Ausnehmung 12 ausgebildet. Um eine drehfeste Kopplung der Vorsatztür 1 mit dem Torsionsstab 4 zu ermöglichen, weist die Ausnehmung 12 zwei zueinander parallele Flächen 14, 15 auf, die über Kreisabschnitte miteinander verbunden sind. In die Ausnehmung 12 wird ein Ende des Torsionsstabs 4 eingesteckt, das entsprechend gegengleich ausgeformt ist. An dem Ende des anderen Schenkels des Aufnahmebeschlags 2 sind Nutabschnitte 16, 17 angeformt, die in die hinterschnittene Nut 11 des Rahmenprofils 8 eingreifen. Zwischen den Nutstücken 16, 17 ist eine Durchgangsbohrung 18 angeordnet, die eine Klemmbefestigung des Aufnahmebeschlags 2 in der Nut 11 ermöglicht, auf die nicht näher eingegangen wird. Der Aufnahmebeschlag 2 wird aus einem stranggepresseten Aluminiumprofil hergestellt.Fig. 3 shows a horizontal section through the mounting bracket 2 for the Torsion bar 4. It is the one connected to the frame profile 8 Receiving fitting. This has an L-shaped profile, is at one end the eye-shaped recess 12 is formed. For a rotationally fixed coupling of the To allow the front door 1 with the torsion bar 4, the recess 12 two mutually parallel surfaces 14, 15 on each other via circular sections are connected. One end of the torsion bar 4 is inserted into the recess 12 inserted, which is shaped correspondingly opposite. At the end of the other Groove sections 16, 17 are integrally formed on the legs of the receiving fitting 2, which engage in the undercut groove 11 of the frame profile 8. Between Groove pieces 16, 17, a through hole 18 is arranged, which is a clamp of the mounting bracket 2 in the groove 11 allows not closer is received. The mounting bracket 2 is made from an extruded Made of aluminum profile.

Fig. 4a ist eine Darstellung des Torsionsstabs 4, wobei dessen mittlerer Abschnitt nicht dargestellt ist. Der Torsionsstab 4 ist aus einem Rundstahl hergestellt, an seinen Endabschnitten 19, 20 sind zwei Parallelflächen ausgebildet, so dass die Endabschnitte 19, 20 in die Ausnehmungen 12 der Aufnahmebeschläge 2 und 3 einsteckbar sind. 4a is an illustration of the torsion bar 4, with its central portion is not shown. The torsion bar 4 is made of round steel its end portions 19, 20 are formed two parallel surfaces, so that the End sections 19, 20 in the recesses 12 of the receiving fittings 2 and 3rd are insertable.

Fig. 4b zeigt den Torsionsstab nach Fig. 4a in einer um 90° gedrehten Ansicht. Wie den Fig. 4a und 4b zu entnehmen ist, liegen die jeweiligen Parallelflächen an einem Endabschnitt des Torsionsstabs 4 nicht symmetrisch zu denen des anderen Endabschnitts, sondern sie sind um einen bestimmten Drehwinkel α bezüglich der Längsachse des Torsionsstabs 4 zueinander verdreht.
Das Profil des Torsionsstabs 4 wird durch die in den Fig. 4c, 4d und 4e dargestellten Schnitte erläutert.4b shows the torsion bar according to FIG. 4a in a view rotated by 90 °. As can be seen from FIGS. 4a and 4b, the respective parallel surfaces on one end section of the torsion bar 4 are not symmetrical to those of the other end section, but are rotated relative to one another by a certain angle of rotation α with respect to the longitudinal axis of the torsion bar 4.
The profile of the torsion bar 4 is explained by the cuts shown in FIGS. 4c, 4d and 4e.

Fig. 4c zeigt den Torsionsstab entlang der Linie I - I in Fig. 4a geschnitten, wobei die Pfeile die Blickrichtung angeben. Die Parallelflächen 21, 22 des oberen Endabschnitts 19 sind um den Drehwinkel α, der in dem dargestellten Ausführungsbeispiel ca. 10° beträgt, gegenüber der Symmetrieachse verdreht.Fig. 4c shows the torsion bar cut along the line I - I in Fig. 4a, wherein the arrows indicate the direction of view. The parallel surfaces 21, 22 of the upper end portion 19 are about the angle of rotation α, which in the illustrated embodiment is about 10 °, rotated with respect to the axis of symmetry.

Fig. 4d zeigt den Torsionsstab nach Fig. 4a entlang der Linie II - II geschnitten, der in diesem Bereich nicht verformt ist und einen runden Querschnitt aufweist.4d shows the torsion bar according to FIG. 4a cut along the line II-II, which is not deformed in this area and has a round cross section.

Fig. 4e zeigt den Torsionsstab entlang der Linie III - III geschnitten. Der Querschnitt entspricht identisch dem in Fig. 4c gezeigten und weist ebenfalls zwei Parallelflächen 23, 24 auf. Zwischen dem oberen Endabschnitten 19 und dem unteren Endabschitt 20 ist dementsprechend ein bestimmter Drehwinkel fest eingestellt. Auf diese Weise lässt sich beim Einbau des Torsionsstabs 4 eine Vorspannung, genauer gesagt ein Vorspannmoment erzeugen, das bei geschlossener Vorsatztür 1 ständig ein schließendes Moment ausübt. Die Montage des Torsionsstabs 4 erfolgt auf einfache Weise, in dem der untere Abschnitt 20 in den ortsfest am Türrahmen 5 angebrachten Aufnahmebeschlag 3 eingesetzt wird. Der obere Aufnahmebeschlag 2 wird in die Nut 11 des Rahmenprofils 8 eingesetzt aber noch nicht fixiert, so dass er entlang der Nut 11 vertikal beweglich ist. Bei geschlossener Vorsatztür 1 liegen die Ausnehmungen 12 in dem oberen und unteren Aufnahmebeschlag 2, 3 exakt übereinander. Dementsprechend muss der obere Endabschnitt 19 des Torsionsstabs 4 zur Montage verdreht werden, damit er in den Aufnahmebeschlag 2 eingesetzt werden kann. Dazu wird mit einem geeigneten Werkzeug, beispielsweise einem Maulschlüssel, dessen lichte Weite den Abstand der beiden Parallelflächen 21, 22 entspricht, der obere Endabschnitt 19 des Torsionsstabs 4 gegriffen und tordiert, bis die Lage der Parallelflächen 21, 22 exakt zu der Ausnehmung 12 des Aufnahmebeschlags 2 ausgerichtet ist. Der Aufnahmebeschlag 2 kann auf dem Torsionsstab 4 aufgeschoben werden, wodurch die Montage abgeschlossen wird.Fig. 4e shows the torsion bar cut along the line III - III. The cross section corresponds identically to that shown in Fig. 4c and also has two parallel surfaces 23, 24 on. Between the upper end portions 19 and the lower End section 20 is accordingly set a certain angle of rotation. In this way, when installing the torsion bar 4, a preload, to be more precise, generate a pretensioning moment that is when the Front door 1 constantly exerts a closing moment. The assembly of the torsion bar 4 takes place in a simple manner in which the lower section 20 in the stationary on the door frame 5 attached mounting bracket 3 is used. The upper Receptacle fitting 2 is still inserted in the groove 11 of the frame profile 8 not fixed, so that it is vertically movable along the groove 11. When closed Front door 1, the recesses 12 are in the upper and lower fitting 2, 3 exactly one above the other. Accordingly, the top end section 19 of the torsion bar 4 are rotated for assembly so that it is in the Support fitting 2 can be used. To do this, use a suitable Tool, for example an open-ended wrench, the clear width of which is the distance of the two parallel surfaces 21, 22 corresponds to the upper end section 19 of the torsion bar 4 gripped and twisted until the position of the parallel surfaces 21, 22 exactly the recess 12 of the receiving fitting 2 is aligned. The admission fitting 2 can be pushed onto the torsion bar 4, whereby the Assembly is completed.
