Description

Die Erfindung betrifft ein Türband zur verdeckten Anordnung zwischen einer Türzarge und einem Türflügel. Das Türband weist zwei Aufnahmekörper zur Befestigung einer Scharnieranordnung des Türbandes an der Türzarge und an dem Türflügel auf. Weiterhin ist an dem Türband ein flexibles elektrisches Verbindungselement angeordnet.The invention relates to a door hinge for concealed arrangement between a door frame and a door leaf. The door hinge has two receiving body for fixing a hinge assembly of the door hinge on the door frame and on the door leaf. Furthermore, a flexible electrical connection element is arranged on the door hinge.

Derartige Türbänder entsprechen dem Bedürfnis des Marktes, Türen nicht nur unsichtbar an einer Türzarge zu befestigen, sondern auch daran angeordnete elektrische Verbraucher und Sensoren ohne sichtbare Kabelverbindung anzuschließen. Mögliche Anwendungsgebiete sind beispielsweise elektrische Türschlösser, Alarmanlagen, Zugangskontrollsysteme, Beleuchtungseinrichtungen und Brandmeldeanlagen.Such door hinges meet the market's need to not only invisibly attach doors to a door frame, but also to connect electrical loads and sensors therewith without visible cable connection. Possible applications include, for example, electric door locks, alarm systems, access control systems, lighting equipment and fire alarm systems.

Ein Türband mit den eingangs beschriebenen Merkmalen ist aus DE 10 2007 041 816 A1 bekannt. Bei dem bekannten Türband ist zwischen den Scharnierbügeln der Scharnieranordnung ein Flachbandkabel durchgeführt, welches durch Aussparungen an der Rückseite aus den Aufnahmekörpern austritt.A door hinge with the features described above is made DE 10 2007 041 816 A1 known. In the known door hinge a ribbon cable is performed between the hinge brackets of the hinge assembly, which emerges through recesses on the back of the receiving bodies.

Bei einem aus US 2011/0 026 204 A1 bekannten Türband ist ein flexibles elektrisches Verbindungselement vorgesehen, das an beiden Enden elektrische Kontaktelemente aufweist. Die Kontaktelemente sind durch ein Kabel miteinander verbunden.At one off US 2011/0 026 204 A1 known door hinge a flexible electrical connection element is provided which has electrical contact elements at both ends. The contact elements are connected by a cable.

Die bekannten Maßnahmen sind montagetechnisch aufwendig. Ferner kann das durch die Scharnieranordnung geführte Kabel durch unkontrollierte Eigenbewegungen während der Betätigungen des Türbandes beschädigt werden. Dies stellt eine ernsthafte Gefahr für die Funktionsfähigkeit der angeschlossenen Geräte dar.The known measures are complicated assembly technology. Furthermore, the cable guided by the hinge arrangement can be damaged by uncontrolled proper movements during the operations of the door hinge. This represents a serious danger to the functionality of the connected devices.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, die Montage des gattungsgemäßen Türbandes zu vereinfachen und darüber hinaus das Risiko von Beschädigungen der elektrischen Verbindung zu verringern.Against this background, the invention has the object to simplify the assembly of the generic door hinge and also to reduce the risk of damage to the electrical connection.

Gegenstand der Erfindung und Lösung dieser Aufgabe ist ein Türband nach Anspruch 1.The object of the invention and solution of this problem is a door hinge according to claim 1.

Erfindungsgemäß weist das flexible elektrische Verbindungselement an beiden Enden ein elektrisches Kontaktelement auf. Die Kontaktelemente sind durch ein mehradriges Kabel miteinander verbunden und jeweils an zugeordneten Aufnahmekörpern fixiert. Die elektrischen Kontaktelemente können als - vorzugsweise handelsübliche - Stecker oder Buchsen ausgebildet sein. Durch die erfindungsgemäße Ausgestaltung ergeben sich mehrere Vorteile: Zum einen kann das Verbindungselement als vorkonfektioniertes Kabel mit zwei Steckverbindungen an den Enden separat produziert oder zugekauft werden. Ein Anschluss der einzelnen Adern des Kabels entfällt sowohl beim Zusammenbau des Türbandes als auch beim Einbau des Türbandes in Türzarge und Türflügel. Auch beim späteren Gebrauch ergibt sich eine Vereinfachung, da elektrische Leitungen am Türflügel und an der Türzarge durch das am Türband angeordnete Verbindungselement besonders einfach und insbesondere auch wieder lösbar elektrisch verbunden werden können. Durch die sichere Fixierung der Kontaktelemente ist eine weitere Befestigung des mehradrigen Kabels nicht notwendig.According to the invention, the flexible electrical connection element has an electrical contact element at both ends. The contact elements are interconnected by a multi-core cable and fixed in each case to associated receiving bodies. The electrical contact elements can be designed as - preferably commercially available - plugs or sockets. The embodiment according to the invention provides several advantages: On the one hand, the connecting element can be produced or purchased separately as a prefabricated cable with two plug connections at the ends. A connection of the individual wires of the cable eliminates both the assembly of the door hinge as well as the installation of the door hinge in door frame and door leaf. Also during later use results in a simplification, since electrical lines on the door and on the door frame by the arranged on the door hinge connection element can be particularly easily and in particular also releasably electrically connected. Due to the secure fixing of the contact elements, a further attachment of the multi-core cable is not necessary.

In einer bevorzugten Ausgestaltung der Erfindung sind die Kontaktelemente in Aussparungen an einer Rückseite der zugeordneten Aufnahmekörper fixiert. Die Aufnahmekörper eines verdeckt liegenden Türbandes weisen einen kastenförmigen Einsatz auf, dessen offene Frontseite im Türschließzustand einer ebenfalls offenen Frontseite des anderen Aufnahmekörpers gegenüberliegt. Die Rückflächen sind somit als diejenigen Flächen des kastenförmigen Abschnittes definiert, welche im Türschließzustand dem jeweils anderen Aufnahmekörper am weitesten beabstandet sind. Durch die entsprechende Anordnung des elektrischen Verbindungselementes wird eine Kabelführung ermöglicht, welche durch die Mechanik der Scharnieranordnung nur unwesentlich gestört wird. Ferner ist eine besonders vorteilhafte Weiterführung der elektrischen Leitung in der Ebene des Türblattes möglich.In a preferred embodiment of the invention, the contact elements are fixed in recesses on a rear side of the associated receiving body. The receiving body of a concealed door hinge have a box-shaped insert, the open front side opposite in the door closed state of an open front side of the other receiving body. The back surfaces are thus defined as those surfaces of the box-shaped portion, which are the furthest spaced in the door closing state of the respective other receiving body. By appropriate arrangement of the electrical connection element a cable guide is made possible, which is disturbed only slightly by the mechanics of the hinge assembly. Furthermore, a particularly advantageous continuation of the electrical line in the plane of the door leaf is possible.

Zweckmäßigerweise ist das mehradrige Kabel als Flachbandkabel ausgebildet. Ein Flachbandkabel hat den Vorteil, dass es in einer Richtung besonders biegsam ausgebildet ist, während es in einer dazu senkrecht stehenden Richtung steifer ist. Dies ist für den vorgesehenen Einsatz insofern vorteilhaft, als das ein Flachbandkabel der Schwenkbewegung des Türbandes besonders gut folgen kann, während es weniger anfällig ist durchzuhängen. Ein durchhängendes Kabel könnte zwischen einzelnen Scharnierbügeln der Scharnieranordnung eingeklemmt und dadurch beschädigt werden. Nichtsdestotrotz soll auch die Verwendung von Rundkabeln und anderen flexiblen Kabeln von der Erfindung umfasst sein.Conveniently, the multi-wire cable is designed as a ribbon cable. A ribbon cable has the advantage that it is particularly flexible in one direction, while it is stiffer in a direction perpendicular thereto. This is advantageous for the intended use in that a ribbon cable can follow the pivotal movement of the door hinge particularly well, while it is less prone to sag. A sagging cable could be pinched between individual hinge straps of the hinge assembly and thereby damaged. Nevertheless, the use of round cables and other flexible cables should also be included in the invention.

In einer Ausführungsvariante ist zumindest ein Kontaktelement durch einen geschäumten Werkstoff und/oder eine Gussmasse mit dem zugeordneten Aufnahmekörper fest verbunden. Hierfür kommen beispielsweise polyurethanbasierte Kunststoffschäume, Kunstharze oder thermoplastische Kunststoffe in Betracht. Gegebenenfalls müssen Dichtmittel zur Verhinderung eines Übertrittes der Werkstoffe vorgesehen sein.In one embodiment, at least one contact element is firmly connected by a foamed material and / or a casting compound with the associated receiving body. For this example, polyurethane-based plastic foams, synthetic resins or thermoplastics come into consideration. Optionally, sealing means must be provided to prevent a transfer of the materials.

In einer anderen Ausführungsvariante der Erfindung ist zumindest ein Kontaktelement durch ein Halteelement formschlüssig an dem zugeordneten Aufnahmekörper fixiert. Dabei stellt das Halteelement den Formschluss zwischen Kontaktelement und Aufnahmekörper her. Ein solches Halteelement kann beispielsweise dazu genutzt werden, einen handelsüblichen Stecker bzw. eine handelsübliche Buchse an der vorgegebenen Geometrie des Türbandes zu befestigen. Auch ist es möglich, je nach Bedarf unterschiedliche Kabel bzw. daraus folgend verschiedene Kontaktelemente mit entsprechend ausgestalteten Halteelementen an dem gleichen Grundkörper eines Türbandes zu befestigen. Somit kann besonders auf die individuellen Bedürfnisse des Kunden eingegangen werden, während der Türbandgrundkörper nicht verändert werden muss. Auch sind Anpassungen für andere Leitungstypen wie z. B. Glasfaserkabel, Wasser- oder Druckluftleitungen, denkbar.In another embodiment variant of the invention, at least one contact element is fixed by a holding element in a form-fitting manner to the associated receiving body. In this case, the holding element establishes the positive connection between the contact element and the receiving body. Such a holding element can be used, for example, to attach a commercially available plug or a commercially available socket to the predetermined geometry of the door hinge. It is also possible to attach different cables or consequent different contact elements with appropriately designed holding elements on the same body of a door hinge as needed. Thus, the individual needs of the customer can be particularly addressed, while the door hinge main body does not need to be changed. Also, adjustments for other types of lines such. As fiber optic cable, water or compressed air lines, conceivable.

In einer zweckmäßigen Ausgestaltung der Erfindung umgreift das Halteelement das zugeordnete Kontaktelement formschlüssig und ist mittels einer Rastverbindung an dem zugeordneten Aufnahmekörper befestigt. Der Formschluss zwischen Halteelement und Kontaktelement wird dadurch hergestellt, dass das Halteelement zumindest teilweise ein Negativprofil zur äußeren Form des Kontaktelementes aufweist. Sinnvollerweise wird das Halteelement durch die Rastverbindung so an dem zugeordneten Aufnahmekörper gehalten, dass das Kontaktelement den Formschluss mit dem Halteelement nicht mehr verlassen kann. Alternativ kann auch das Halteelement so ausgebildet sein, dass sich zwischen Kontaktelement und Halteelement eine weitere Rastverbindung ergibt, welche den Formschluss der beiden Teile sichert.In an advantageous embodiment of the invention, the holding element surrounds the associated contact element positively and is fastened by means of a latching connection to the associated receiving body. The positive connection between the holding element and contact element is produced in that the holding element has at least partially a negative profile to the outer shape of the contact element. It makes sense, the holding element is held by the latching connection to the associated receiving body, that the contact element can not leave the positive connection with the holding element. Alternatively, the holding element may be formed so that there is a further latching connection between the contact element and the holding element, which ensures the positive connection of the two parts.

In einer besonders bevorzugten Ausgestaltung weist das Halteelement als mehrteiliges Bauteil zwei Schalen auf, die das zugeordnete Kontaktelement formschlüssig umgreifen und mittels einer Rastverbindung in einer Aussparung des zugeordneten Aufnahmekörpers fixiert sind. Dabei hält die Berandung der Aussparung die Schalen formschlüssig an dem Kontaktelement. Gemäß dieser Ausgestaltung kann eine besonders einfache Montage verwirklicht werden. Zur Montage wird das Kontaktelement zunächst zwischen die Schalen des Halteelementes eingelegt. Die Schalen können dabei zunächst lediglich lose anliegen, was insbesondere auch die Demontage vereinfacht. Anschließend wird das Halteelement mittels einer Rastverbindung in einer zugeordneten Aussparung des Aufnahmekörpers fixiert. Die Rastverbindung gestaltet sich dabei als besonders vorteilhaft, da kein weiteres Werkzeug benötigt wird. Jedoch sind auch andere Befestigungsverfahren wie beispielsweise Schraubverbindungen von der Erfindung umfasst. Durch die Berandung der Aussparung werden die Teile des Halteelementes so zusammengehalten, dass der Formschluss mit dem Kontaktelement sichergestellt ist. Somit wird ein zuverlässiger, indirekter Formschluss zwischen Aufnahmekörper und Kontaktelement hergestellt. Je nach Ausgestaltung kann durch große Kontaktflächen eine besonders wirksame Kraftübertragung sichergestellt werden. Ferner kann das Halteelement auch eine Schutzfunktion für das umgriffene Kontaktelement und gegebenenfalls umgriffene Teile des Kabels übernehmen.In a particularly preferred embodiment, the holding element as a multi-part component on two shells, which engage around the associated contact element form fit and by means of a latching connection in a recess the associated receiving body are fixed. The boundary of the recess holds the shells positively on the contact element. According to this embodiment, a particularly simple assembly can be realized. For assembly, the contact element is first inserted between the shells of the holding element. The shells can initially only lie loosely, which in particular simplifies the disassembly. Subsequently, the holding element is fixed by means of a latching connection in an associated recess of the receiving body. The latching connection is designed to be particularly advantageous because no additional tools are needed. However, other attachment methods such as threaded connections are also included in the invention. By the boundary of the recess, the parts of the holding element are held together so that the positive connection is ensured with the contact element. Thus, a reliable, indirect positive connection between the receiving body and contact element is produced. Depending on the configuration, a particularly effective power transmission can be ensured by large contact surfaces. Furthermore, the holding element can also take over a protective function for the engaged contact element and optionally gripped parts of the cable.

Andere konstruktive Ausgestaltungen, insbesondere Mehrgelenkanordnungen sind ebenfalls möglich.The Fig. 1 shows a horizontal, approximately centered section through a door hinge according to the invention. The door hinge has two receiving body 1, 1 'for attaching a hinge assembly 2 of the door hinge to a door frame and a door leaf. Since the hinge assembly 2 has a known configuration for a concealed door hinge, this will be described only briefly: In the receiving bodies 1, 1 'are on two guide elements hingedly interconnected hinge bracket 4, 4' rotatably mounted. In addition, the hinge bracket 4, 4 'in a slotted guide of the guide elements 3 are guided pivotably and slidably. The guide elements 3 are attached to the receiving bodies 1, 1 '. Other structural configurations, in particular multi-joint arrangements are also possible.

Die Aufnahmekörper 1, 1' weisen jeweils eine Vorderseite 5 auf, welche sich beim geschlossenen Türband, das heißt im Türschließzustand, gegenüberstehen. Die Vorderseiten 5 weisen eine Öffnung auf, durch welche die Scharnierbügel 4, 4' hindurchgreifen. In der Fig. 1 ist die Öffnungsstellung dargestellt, in welcher die Vorderseiten 5 nebeneinander parallel liegen. An den Aufnahmenkörpern 1, 1' sind jeweils den Vorderseiten 5 gegenüberliegend Rückwände 6 angeordnet. Das Türband umfasst ferner ein flexibles elektrisches Verbindungselement 7.The receiving body 1, 1 'each have a front side 5, which in the closed door hinge, that is in the door closing state, face each other.

Die Kontaktelemente 8, 8' sind mittels Halteelementen 10, 10' an den Aufnahmekörpern 1, 1' fixiert.According to the invention, contact elements 8, 8 'are arranged at both ends of the connecting element 7, for example in the form of plugs, which are connected to one another by a ribbon cable 9. The contact elements 8, 8 'are fixed by means of holding elements 10, 10' to the receiving bodies 1, 1 '.

Der Darstellung in Fig. 2 entnimmt man, dass das dort dargestellte Halteelement 10 mittels Rastnasen 11 in einer Aussparung in der Rückwand 6 des zugeordneten Aufnahmekörpers 1 gehalten ist. Ein weiteres Einschieben wird durch einen flanschartigen Vorsprung 12 verhindert. In dem dargestellten montierten Zustand steht an der Rückseite 6 des Aufnahmekörpers 1 von dem elektrischen Verbindungselement 7 ausschließlich der Stecker 8 vor. Das mehradrige Flachbandkabel 9 ist vor Beschädigungen geschützt innerhalb des Türbandes angeordnet. Bei geöffnetem Türband wird es nach außen durch den Scharnierbügel 4, an dem es innenseitig anliegt, abgeschirmt.The representation in Fig. 2 one assumes that the retaining element 10 shown there is held by means of locking lugs 11 in a recess in the rear wall 6 of the associated receiving body 1. Further insertion is prevented by a flange-like projection 12. In the assembled state shown, only the plug 8 protrudes from the electrical connection element 7 on the rear side 6 of the receiving body 1. The multi-core ribbon cable 9 is protected from damage within the door hinge. When the door hinge is open, it is shielded to the outside by the hinge bracket 4, where it rests on the inside.

Aus der Fig. 3 wird der Aufbau der Halteelemente 10, 10' deutlich. Die beiden Halteelemente 10, 10' bestehen aus zwei schalenartigen Elementen 10a, 10b, welche den zugeordneten Stecker 8 formschlüssig umgreifen. Bei aneinanderliegenden Schalen 10a, 10b wird ein Herausrutschen des Steckers 8 wirksam verhindert. Die formschlüssige Verbindung wird dadurch hergestellt, dass eine Ausbuchtung 13 des Steckers 8 in eine zugehörige Aufnahme der einen Schale 10a einführbar ist. Dabei kann ein Sicherungshaken 14 zur Sicherung eines Anschlusses an dem Stecker 8 unterseitig aus dem Halteelement 10 herausragen. Die gegenüberliegende Schale 10b greift mit einer abgewinkelten Kante 15 in eine zugeordnete Nut 16 des Steckers 8 ein.From the Fig. 3 the structure of the holding elements 10, 10 'becomes clear. The two holding elements 10, 10 'consist of two shell-like elements 10a, 10b, which surround the associated connector 8 in a form-fitting manner. In adjacent shells 10a, 10b slipping out of the plug 8 is effectively prevented. The positive connection is produced in that a bulge 13 of the plug 8 in an associated receptacle of a shell 10 a can be inserted. In this case, a securing hook 14 for securing a connection to the plug 8 on the underside of the holding element 10 protrude. The opposite shell 10b engages with an angled edge 15 in an associated groove 16 of the plug 8 a.
