Description

The present invention relates to a door hinge arrangement comprising one a hinge to be arranged on a door leaf and one on a frame to be arranged band clamp, which can be pivoted to form a hinge connectable with each other and for the passage of electrical cables are trained.

Door hinge arrangements of the generic type are used everywhere where in the interior of the door leaf electrical lines for carrying electrical Energy and / or data signals is required, for example at Use of electrical locking systems, security sensors and the like. In the prior art, such lines with a large excess length are provided by the customer moved forward into the frame area of a door and with a corresponding one Cable bushings provided door hinge arrangement into the inside of a Door leaf led to the junction and connected there.

Door hinge arrangements of the generic type are called a door hinge dummy used. They are used exclusively for cable routing, without load capacities be taken over. Such hinge arrangements are identical to that carrying door hinges and tamper-proof insofar as the different Door hinges are not identifiable in terms of load-bearing or cable-routing. However, such door hinge arrangements can also contribute partially or completely simultaneous cable entry are trained when the structural Conditions, door weights and the like allow this.

The required pulling through the cables is a time-consuming and Part of difficult assembly work. This is especially true if, as in Security areas, steel doors are used, which with the elements a hinge arrangement can be connected by welding. The occurring Temperature often leads to damage to the insulation of lines. If for Avoiding pulling through electrical lines, i.e. energy and / or Data lines that are routed through flexible parallel channels are not tamper-proof.

Repairing damaged cables is a particular problem. Lines can easily be caused by the frequent swiveling of the hinge damage to the door block. This then makes a complete, subsequent pulling through lines required, which is also time and is assembly-intensive. This also applies in the event that to adapt to a Power requirements additional lines are required. This still results in a particular problem from the need to have hinge plates and door brackets in their align relative position to each other. One speaks of the so-called Height adjustment. The frame-side line openings and the door leaf side Line openings write fixation positions for the band flap and the Doorknobs in front, which are not necessarily optimal when installed Height positioning of both elements relative to each other to provide a perfect pivotability of the door leaf with respect to the frame bring. There are possibilities for height compensation from the prior art not known.

Starting from the above-described prior art, the present invention is based on the object of providing a door hinge arrangement of the generic type which enables simple installation of both the door hinge arrangement and the electrical lines, can be designed to be repair-friendly and tamper-proof, and is flexible with regard to adaptation to the on-site installation conditions is.

For the technical solution it is proposed with the invention that at least one of the two elements hinge flap or block has a cavity for concealed reception of a line interface formed from at least one plug / socket arrangement and, in the assembled state, lines guided through the door hinge arrangement can be connected to the line interface.
