Description

Die Erfindung betrifft einen Türspion, der ein rohrförmiges Gehäuse zum Einsetzen in einen Durchbruch eines Türblattes aufweist, wobei das Gehäuse eine optische Einrichtung trägt gemäß dem Oberbegriff von Anspruch 1, sowie ein Trennelement für einen gattungsgemäßen Türspion gemäß dem Oberbegriff von Anspruch 13.The invention relates to a door viewer, which has a tubular housing for insertion into an opening of a door leaf, wherein the housing carries an optical device according to the preamble of claim 1, and a separating element for a generic peephole according to the preamble of claim 13.

Türspione dieser Art sind seit Jahren bekannt und werden entweder als einteiliges, rohrförmiges Gehäuse, das die optische Einrichtung trägt und in einen Durchbruch eines Türblattes eingesetzt wird, ausgeführt, oder auch als zweiteiliges Gehäuse, wobei die jeweiligen Teilstücke von jeweils einer Außenseite des Türblattes in den Durchbruch eingeführt und miteinander etwa verschraubt werden. Das Gehäuse bzw. die Teilstücke des Gehäuses werden dabei, insbesondere für einen Einsatz in Feuerschutztüren, aufgrund der besseren Temperaturbeständigkeit aus einem metallischen Werkstoff gefertigt.Door spies of this type have been known for years and are either a one-piece, tubular housing, which carries the optical device and is inserted into an opening of a door leaf, executed, or as a two-part housing, wherein the respective sections of each of an outer side of the door leaf in the Breakthrough introduced and screwed together about. The housing or the parts of the housing are made, in particular for use in fire doors, due to the better temperature resistance of a metallic material.

Dabei stellt sich aber das Problem, dass bei großer Wärmeentwicklung auf einer Seite des Türblattes der Türspion eine Wärmebrücke auf die gegenüberliegende Seite des Türblattes bildet. Aufgrund von Brandschutzbestimmungen ist aber vorgesehen, dass die Wärmeübertragung auf die gegenüberliegende Seite gewisse Werte nicht überschreiten darf. Insbesondere ergeben sich Schwierigkeiten, wenn der Türspion gemeinsam mit einer an einer Türblattaußenseite anliegenden Abdeckplatte, etwa ein Namensschild, ausgeführt werden soll, da die Abdeckplatte, die ebenfalls zumeist aus einem metallischen Werkstoff besteht, im Brandfall eine beträchtliche Wärmequelle auf der brandabgewandten Seite des Türblattes darstellen kann.However, there is the problem that with large heat development on one side of the door leaf of the spyhole forms a thermal bridge on the opposite side of the door leaf. Due to fire regulations, however, it is provided that the heat transfer to the opposite side may not exceed certain values. In particular, difficulties arise when the peephole with a voltage applied to a door leaf outside cover plate, such as a nameplate to be executed because the cover plate, which is also usually made of a metallic material, in case of fire, a significant heat source on the brandabgewandten side of the door panel can.

Die durch einen Türspion mit metallischem Gehäuse gebildete Wärmebrücke weist des weiteren auch den Nachteil auf, dass bei Hauseingangstüren oder Laubengangtüren, die von Wohnräumen direkt ins Freie führen, es zur Bildung von Kondenswasser kommen kann, das die Funktion des Türspions beeinträchtigt.The thermal bridge formed by a peephole with a metallic housing also has the disadvantage that in the case of entrance doors or pergola doors, which lead directly from living spaces into the open, it can lead to the formation of condensation, which impairs the function of the fish peephole.

Es ist daher das Ziel der Erfindung einen Türspion vorzusehen, der diese Nachteile vermeidet. Insbesondere soll ein Türspion geschaffen werden, der im Brandfall eine Wärmeübertragung über das Gehäuse des Türspions reduziert und somit vorgeschriebene Brandschutzbestimmungen erfüllt. Des weiteren soll der erfindungsgemäße Türspion die Bildung von Kondenswasser vermeiden.It is therefore the object of the invention to provide a door viewer which avoids these disadvantages. In particular, a door viewer should be created, which reduces heat transfer through the housing of the door spy in the event of fire and thus fulfills prescribed fire protection regulations. Furthermore, the door viewer according to the invention should avoid the formation of condensation.

Diese Ziele werden durch die Merkmale von Anspruch 1 bzw. 13 erreicht.These objects are achieved by the features of claims 1 and 13, respectively.

Anspruch 1 bezieht sich hierbei auf einen Türspion, der ein rohrförmiges Gehäuse zum Einsetzen in einen Durchbruch eines Türblattes aufweist, wobei das Gehäuse eine optische Einrichtung trägt. Erfindungsgemäß ist vorgesehen, dass zumindest ein Trennelement vorgesehen ist, das das Gehäuse in zumindest zwei, in axialer Richtung nebeneinander liegende Teilstücke unterteilt, wobei zumindest eines der Trennelemente eine niedrigere Wärmeleitfähigkeit als die beiden angrenzenden Teilstücke aufweist. Durch ein Trennelement dieser Art wird somit die durch das Gehäuse des Türspions gebildete Wärmebrücke unterbrochen, sodass die Wärmeübertragung auf die gegenüberliegende Seite des Türblattes reduziert wird. Damit kann aber auch etwa die Bildung von Kondenswasser vermieden werden.Claim 1 here refers to a spyhole, which has a tubular housing for insertion into an opening of a door leaf, wherein the housing carries an optical device. According to the invention, it is provided that at least one separating element is provided, which subdivides the housing into at least two sections lying next to one another in the axial direction, wherein at least one of the separating elements has a lower thermal conductivity than the two adjacent sections. By a separator of this kind thus formed by the housing of the door spy thermal bridge is interrupted, so that the heat transfer is reduced to the opposite side of the door leaf. But this can also be about the formation of condensation avoided.

Anspruch 2 bezieht sich auf eine Ausführungsvariante, bei der genau ein Trennelement vorgesehen ist, das das Gehäuse in zwei, in axialer Richtung nebeneinander liegende und jeweils zur Türblattaußenfläche gerichtete Teilstücke unterteilt.Claim 2 refers to a variant in which exactly one separating element is provided which the housing in two, juxtaposed in the axial direction and each directed to the door leaf outer surface sections divided.

Anspruch 3 schlägt vor, das Trennelement hülsenförmig auszuführen, wobei gemäß Anspruch 4 das Trennelement endseitige Gewindeabschnitte zur Verschraubung mit den Teilstücken aufweist. Es wäre alternativ aber auch etwa möglich, eine Steckverbindung zwischen dem Trennelement und den angrenzenden Teilstücken des Gehäuses vorzusehen.Claim 3 proposes to perform the separator sleeve-shaped, wherein according to claim 4, the separating element has end-side threaded portions for screwing with the sections. It would alternatively be possible but about to provide a plug connection between the separating element and the adjacent sections of the housing.

Gemäß Anspruch 5 ist vorgesehen, dass die Teilstücke aus einem metallischen Werkstoff und das Trennelement aus einem Kunststoff, vorzugsweise ein Polyamid, gefertigt ist. Kunststoffe weisen eine geringere Wärmeleitfähigkeit als metallische Werkstoffe auf und eignen sich somit besonders für die Unterbrechung einer Wärmebrücke. Andererseits sollte bei der Wahl des Kunststoffs darauf geachtet werden, dass er über eine ausreichende Temperaturbeständigkeit verfügt.According to claim 5 it is provided that the sections of a metallic material and the separating element of a plastic, preferably a polyamide, is made. Plastics have a lower thermal conductivity than metallic materials and are therefore particularly suitable for interrupting a thermal bridge. On the other hand, care should be taken when choosing the plastic that it has sufficient temperature resistance.

Der erfindungsgemäße Türspion eignet sich insbesondere auch für die Verwendung mit an einer Türblattaußenfläche anliegenden Abdeckplatte, sodass gemäß Anspruch 6 vorgeschlagen wird, an zumindest einem Endabschnitt des Gehäuses eine Abdeckplatte vorzusehen, die in Gebrauchslage des Türspions an einer Außenfläche des Türblattes anliegt. Gemäß Anspruch 7 handelt es sich hierbei um ein Namensschild.The inventive peephole is particularly suitable for use with adjacent to a door leaf outer cover plate so that it is proposed according to claim 6, to provide at least one end portion of the housing a cover plate which rests in the position of use of the fish pee on an outer surface of the door leaf. According to claim 7, this is a name tag.

Um die Bildung von Kondenswasser im Inneren des Türspions und insbesondere an den optischen Elementen effektiver zu unterbinden, sind die Merkmale der Ansprüche 8 bis 12 vorteilhaft. Anspruch 8 sieht dabei vor, dass im Trennelement zumindest ein durchsichtiges Einsatzelement angeordnet ist, das den lichten Querschnitt des Trennelements abdeckt. Gemäß Anspruch 9 ist dieses Einsatzelement in einem der Teilstücke angeordnet. Dadurch wird der Wärmeaustausch über die im Inneren des Türspions zirkulierende Luft unterbunden, sodass neben der Wärmeübertragung über Wärmeleitung entlang des Gehäuses auch die Wärmeübertragung über Wärmekonvektion verhindert wird. Gemäß Anspruch 10 ist das Einsatzelement aus Glas gefertigt, und gemäß Anspruch 11 aus Kunststoff. In bevorzugter Weise ist gemäß Anspruch 12 das Einsatzelement plättchenförmig ausgeführt.In order to more effectively prevent the formation of condensation in the interior of the fish peephole and in particular on the optical elements, the features of claims 8 to 12 are advantageous. Claim 8 provides that in the separating element at least one transparent insert element is arranged, which covers the clear cross-section of the separating element. According to claim 9, this insert element is in one of the sections arranged. As a result, the heat exchange is prevented by the air circulating in the interior of the door spy, so that in addition to the heat transfer via heat conduction along the housing and the heat transfer is prevented by heat convection. According to claim 10, the insert element is made of glass, and according to claim 11 of plastic. Preferably, according to claim 12, the insert element is made platelet-shaped.

Die Ansprüche 13 bis 20 beziehen sich schließlich auf ein entsprechendes Trennelement.Finally, claims 13 to 20 relate to a corresponding separating element.

Die Erfindung wird im folgenden anhand der beiliegenden Zeichnungen näher erläutert. Es zeigen hierbei die

Anhand der Fig. 1 werden zunächst die Einzelteile eines erfindungsgemäßen Türspions erläutert, wobei die Einzelteile noch nicht zusammengefügt sind. Es sind hierbei in der gezeigten Ausführungsform die beiden Teilstücke 8 und 9 ersichtlich, wobei etwa das Teilstück 8 mit einer optischen Einrichtung 1 versehen ist und in Gebrauchslage des Türspions in den Außenbereich eines durch das Türblatt 6 (in der Fig. 1 nicht dargestellt) abgegrenzten Wohnraumes gerichtet ist. Das Teilstück 9 ist in Gebrauchslage des Türspions in den Wohnraum gerichtet. Das Teilstück 9 kann mit einer Abdeckung 4 versehen sein, das in Gebrauchslage des Türspions an der in den Wohnraum gerichteten Außenfläche des Türblattes 6 anliegt. Die beiden Teilstücke 8 und 9 bestehen, insbesondere bei Feuerschutztüren, in der Regel aus einem metallischen Material.1, the individual parts of a door spy according to the invention are first explained, wherein the items are not yet joined together. In the embodiment shown here, the two sections 8 and 9 can be seen, whereby approximately the section 8 is provided with an optical device 1 and in the position of use of the peephole in the outer area of a through the door leaf 6 (not shown in FIG. 1) demarcated Housing is addressed. The section 9 is directed in the position of use of the peephole in the living room. The portion 9 may be provided with a cover 4, which abuts in the position of use of the fish peephole on the directed into the living space outer surface of the door leaf 6. The two sections 8 and 9 are, especially in fire doors, usually made of a metallic material.

Um den Wärmetransport zwischen den beiden Teilstücken 8 und 9 zu reduzieren ist erfindungsgemäß nun ein Trennelement 2 vorgesehen, das aus einem Material mit niedrigerer Wärmeleitfähigkeit als die beiden Teilstücke 8 und 9 gefertigt ist. Hierzu eignet sich etwa ein Kunststoff, beispielsweise ein Polyamid. Gemäß der in Fig. 1 gezeigten Ausführungsform ist das Trennelement hülsenförmig ausgeführt und weist zur Verschraubung mit den beiden Teilstücken 8 und 9 an seinen beiden Endabschnitten jeweils einen Gewindeabschnitt 10 und 11 auf. Dabei handelt es sich etwa bei dem Gewindeabschnitt 10 um ein Innengewinde, das mit einem ihm zugeordneten Gewindeabschnitt 7 des Teilstücks 8, das als Außengewinde ausgeführt ist, verschraubbar ist. Bei dem Gewindeabschnitt 11 kann es sich etwa um ein Außengewinde handeln, das mit einem ihm zugeordneten Gewindeabschnitt 3 des Teilstücks 9, das als Innengewinde ausgeführt ist, verschraubbar ist.In order to reduce the heat transfer between the two sections 8 and 9, a separator 2 is now provided according to the invention, which is made of a material with lower thermal conductivity than the two sections 8 and 9. A plastic, for example a polyamide, is suitable for this purpose. According to the embodiment shown in Fig. 1, the separating element is designed sleeve-shaped and has for screwing with the two sections 8 and 9 at its two end portions each have a threaded portion 10 and 11. These are approximately in the threaded portion 10 to an internal thread, which is screwed with an associated threaded portion 7 of the section 8, which is designed as an external thread. The threaded portion 11 may be about an external thread, which with a associated with him threaded portion 3 of the portion 9, which is designed as an internal thread, can be screwed.

Die Fig. 2 zeigt die Einzelteile des erfindungsgemäßen Türspions gemäß Fig. 1 im verschraubten Zustand, wobei die beiden Teilstücke 8 und 9 sowie das Trennelement 2 ein Gehäuse bilden, das in einen Durchbruch eines Türblattes 6 (in der Fig. 2 nicht dargestellt) eingesetzt werden kann.FIG. 2 shows the individual parts of the door spy according to the invention according to FIG. 1 in the screwed state, wherein the two sections 8 and 9 as well as the separating element 2 form a housing inserted into an opening of a door leaf 6 (not shown in FIG. 2) can be.

Ein erfindungsgemäßer Türspion in Gebrauchslage ist in der Fig. 3 ersichtlich, wobei die beiden Teilstücke 8 und 9 mit dem dazwischenliegenden Trennelement 2 verschraubt und in einen Durchbruch eines Türblattes 6 eingesetzt sind. Des weiteren ist in der Fig. 3 eine Abdeckplatte 5 ersichtlich, die im montierten Zustand des Türspions an der in den Außenbereich gerichteten Außenfläche des Türblattes 6 anliegt. Die Abdeckplatte 5 besteht in der Regel aus einem metallischen Werkstoff und kann etwa ein Namensschild sein.An inventive peephole in the use position is shown in FIG. 3, wherein the two sections 8 and 9 are screwed to the intermediate separating element 2 and inserted into an opening of a door leaf 6. Furthermore, in Fig. 3, a cover plate 5 can be seen, which abuts in the mounted state of the fish peephole on the outer surface facing the outer surface of the door panel 6. The cover plate 5 is usually made of a metallic material and may be about a nameplate.

Die Abdeckplatte 5 ist auch in der Fig. 4 ersichtlich, die das Türblatt 6 im Aufriss mit einem erfindungsgemäßen Türspion zeigt. Vom Türspion ist in der Fig. 4 allerdings nur die optische Einrichtung 1 zu sehen.The cover plate 5 can also be seen in FIG. 4, which shows the door leaf 6 in elevation with a door spy according to the invention. From the peephole, however, only the optical device 1 can be seen in FIG. 4.

Um die Bildung von Kondenswasser im Inneren des Türspions und insbesondere an den optischen Elementen der otpischen Einrichtung 1 effektiver zu unterbinden, kann im Trennelement 2 zumindest ein durchsichtiges Einsatzelement 12 angeordnet ist, das den lichten Querschnitt des Trennelements 2 abdeckt (Fig. 5, Fig. 6). Dieses Einsatzelement 12 kann aber auch in einem der Teilstücke 8, 9 angeordnet sein. Dadurch wird der Wärmeaustausch über die im Inneren des Türspions zirkulierende Luft unterbunden, sodass neben der Wärmeübertragung über Wärmeleitung entlang des Gehäuses auch die Wärmeübertragung über Wärmekonvektion verhindert wird. Das Einsatzelement kann aus Glas oder Kunststoff gefertigt sein, und ist in bevorzugter Weise plättchenförmig ausgeführt. Das Einsatzelement 12 muss abgesehen von dessen Durchsichtigkeit keine anderen optischen Eigenschaften aufweisen, es könnte aber vorgesehen sein, das Einsatzelement 12 etwa als Linse auszuführen, um eine Fokussierung oder eine Aufweitung des Strahlenganges zwischen der optischen Einrichtung 1 und der gegenüberliegenden Seite des Türblattes 6 zu erreichen.In order to more effectively prevent the formation of condensation in the interior of the peephole and, in particular, on the optical elements of the optical device 1, at least one transparent insert element 12 can be arranged in the separating element 2, covering the clear cross section of the separating element 2 (FIG. 5, FIG. 6). However, this insert element 12 can also be arranged in one of the sections 8, 9. As a result, the heat exchange is prevented by the circulating air inside the door spy, so that in addition to the heat transfer via heat conduction along the housing and the heat transfer is prevented by heat convection. The insert element may be made of glass or plastic, and is preferably platelet-shaped. The insert element 12, apart from its transparency, need not have any other optical properties, but it could be provided to make the insert element 12 approximately as a lens in order to achieve focusing or widening of the beam path between the optical device 1 and the opposite side of the door leaf 6 ,

Durch das Trennelement 2 wird somit die durch das Gehäuse des Türspions gebildete Wärmebrücke unterbrochen, sodass die Wärmeübertragung auf die gegenüberliegende Seite des Türblattes reduziert wird. Insbesondere kann etwa bei einem Brandfall im Wohnbereich die Wärmeübertragung auf das Namensschild 5, das sich im Außenbereich befindet, verringert werden. Durch das Trennelement 2 kann aber auch etwa die Bildung von Kondenswasser vermieden werden.Thus, the heat bridge formed by the housing of the door spy is interrupted by the separating element 2, so that the heat transfer is reduced to the opposite side of the door leaf. In particular, in the event of a fire in the living area, for example, the heat transfer to the name badge 5, which is located in the outer area, can be reduced. By the separation element 2 but also about the formation of condensation can be avoided.
