Description

The present invention relates to a door hinge assembly comprising a hinge flap to be arranged on a door leaf and a band clamp to be arranged on a frame, which are designed for the passage of electrical lines.

Door hinge assemblies of the generic type are used wherever electrical wiring for guiding electrical energy and / or data signals is required in the interior of the door leaf, for example in the use of electrical locking systems, safety sensors and the like. In the prior art, such lines are advanced with large excess length up to the Zargenbereich a door on site and guided by a corresponding provided with cable ducts door hinge assembly into the interior of a door panel to the junction and connected there.

Other door hinge assemblies, which are designed for the implementation of electrical lines, are known from the prior art. For example, US 4,671,582 discloses a pivot pin assembly for a swing door that includes a double-ended electrical connector. This pivot pin assembly includes a pivot pin and a sliding connection means with which the pivot pin is relatively rotatably in communication. For an electrical power supply of elements which are arranged within the swinging door, by the sliding connection means and the pivot pin is one of for example three Cables existing electrical connection out. To form the electrical contact between the elements to be supplied with electrical energy and the current-carrying cables end of the pivot pin a connector socket is attached to the pivot pin. For a positionally accurate connection of the sliding connection device with a coupling device, the sliding connection device is provided with a feather key, which engages in a correspondingly formed recess of the coupling device.

Furthermore, from the prior art according to US 3,555,695 the design of plug contacts for connecting electrical lines in connection with the design of a hinge for a door of a motor vehicle has become known. The plug contacts shown here are formed by two relatively rotatably arranged metal extensions, which are arranged between insulating spacers. Both the spacers and the rotatable relative to one another arranged plug contacts are penetrated by a rotation axis about which the control contacts are rotatably arranged. In the mounted state, the live cables are connected to the plug contacts by means of a cable lug. When opening the car door, the plug contacts pivot about the axis of rotation, so that even with a rotational movement of the door, the electrical contact between the current-carrying cables is maintained.

Likewise, door hinge arrangements are known from the prior art, which are used as door hinge dummy. They are used exclusively for cable entry without carrying capacity. Such door hinge assemblies are identical to the load-bearing door hinges and are sabotage-safe in that the various door hinges are not identifiable in terms of carrying or cable passing. However, such door hinge assemblies may also be formed partially or fully supported with simultaneous cable entry if structural conditions, door weights, and the like permit.

In this case, the required cable pulling is a time-consuming and sometimes difficult assembly effort. This is especially true when, as in security areas, steel doors are used, which are connected to the elements of a door hinge assembly by welding. The occurring temperature often leads to damage to the insulation of cables. If necessary to avoid pulling through electrical lines, so energy and / or Data lines, are guided by flexible parallel channels, these are not sabotagesicher.

A particular problem is the repair of damaged cables. Cables can easily be damaged by the frequent pivoting of the hinge against the door handle. This then makes a complete, subsequent pulling through of lines required, which is also time consuming and easy to install. This also applies in the event that additional lines are required to adapt to a power requirement. This results in a particular problem from the need to align hinge tabs and door handles in their relative position to each other. One speaks of the so-called height compensation. The frame-side pipe openings and the door leaf-side pipe openings prescribe fixation positions for the hinge tab and the door latch, which do not necessarily bring an optimal height positioning of both elements relative to each other in the installed state to provide proper pivotability of the door leaf relative to the frame. From the state of the art possibilities for height compensation are not known.

Starting from the above prior art, the present invention has for its object to provide a hinge arrangement of the generic type which allows a simple assembly of both the door hinge arrangement as well as the electrical wiring, easy to repair and can be made tamper-proof and to adapt to the installation on site conditions flexible with regard to is.

For technical solution is proposed with the invention, a door hinge assembly with line interface comprising a hinge plate to be arranged on a door leaf and a band to be arranged on a frame clamp which are connected to form a hinge dumbbell pivotally connected to each other and formed to carry electrical lines, at least one the two elements hinge tab or -klawing has a cavity for concealed receiving the cable interface formed from at least one plug / socket assembly and guided in the assembled state by the door hinge assembly lines are connected to the line interface and wherein a base plate for pre-assembly to a door leaf or a door frame and is provided for receiving an element of a male / female arrangement.

The invention provides to form a door hinge assembly as a hinge dummy, wherein at least one of the two elements band tabs to provide a cavity, which is suitable concealed to receive a male / female arrangement as a line interface. The lines are then led to the corresponding connection area and there arranged on a plug or a socket. This can be pre-assembled on site. In the arrangement of the door hinge now gives the opportunity to connect the ends of guided through the door hinge assembly lines to the corresponding counter element and to connect the two elements of the male / female arrangement together.

The inventive design of the door hinge assembly, the assembly is now considerably simplified because electrical connection work on the one hand and mechanical assembly work on the other hand can be decoupled from each other. Also, repairs are much easier. The simplified assembly eliminates the need for parallel guidance of cables through flexible transfer channels, making the arrangement safer against sabotage. The tracking of other lines is greatly simplified.

According to the invention a base plate for pre-assembly on the door leaf or the door frame is present on which on the one hand an element of the plug / socket assembly is attached and which on the other hand provides the attachment points for the mechanical arrangement of Bandklobens or hinge flap. This makes electrical pre-assembly easy and safe. At corresponding openings in the region of the frame or the door base plates are arranged, which connected to the respective element of the plug / socket assembly connected from the openings and attached the element to the base plate. There is thus a simple and secured against damage line connection point available. In addition, the base plate on the attachment points for the hinge strap and the Bandkloben.

The hinge tab or the band clamp are formed according to a further advantageous proposal of the invention as a cap member and thus as a cap placed on the base plate and attachable to this. For fastening a screw is proposed in an advantageous manner. Here, advantageously, threaded plates or sheet metal nuts arranged base plate side and the hinge tab or Bandkloben be secured by tapping screws to the base plate. To increase the sabotage security is proposed with the invention to seal the screw heads or aufzubohren and then fill or paint. Thus, the screw heads are invisible and secured against tool access.

Advantageously, both the hinge tab and the band clamp are designed according to the invention and special advantages arise when a base plate is used on both sides, which is designed both for receiving an element of the plug / socket assembly and at the same time provides the fasteners for the hinge tab or Bandkloben , Although the base plates need not be basically provided with fasteners for the hinge strap or Bandkloben, the number of items is reduced to a minimum by this proposal according to the invention proposal. If the invention is used both bandlappen- and bandklobenseitg, there is the particular advantage that both the frame side and the door side in the manner described lines connected to an element of a plug / socket assembly and this element is attached in the frame or the door leaf. It is now only necessary to lead through the door hinge assembly lines and connect at both ends to a corresponding element of a plug / socket assembly. The electrical installation is thus reduced to produce both sides of the socket and door leaf side a male / female connection. If base plates are used with mounting connections for the hinge strap or band clamps, now the mechanical assembly is reduced to put the cap-like elements on the respective base plates and fasten for example by means of screws or other suitable fastening means to the base plate.

According to an advantageous proposal of the invention, standard interfaces can be used as elements of the plug / socket arrangement. Here, for example, known from the field of computer electronics known interfaces such as parallel or serial interfaces, RS 232, "Sub-D connector" or the like.

According to a further advantageous proposal of the invention, a ribbon cable is used as the cable to be passed through hinge tabs and tape tabs. According to a particularly advantageous proposal of the invention, this is introduced spirally into the bushing. Thus, the cable is largely secured against damage due to the pivoting of the door relative to the frame. According to a further advantageous proposal of the invention, a cable protection channel can be provided in the cable bushing. The use of, for example, 24-pin ribbon cable is advantageous. Optionally, a line redundancy or the provision of line expansions may be provided here.

According to an advantageous proposal of the invention, band clamps and the hinge tabs can be formed as a preassembled unit together with the ducts which are provided at their ends with corresponding interface elements. As a result, both the installation and any repairs are considerably simplified.

Advantageously, it is proposed that the band tab and the band clamp are telescopically slidably connected to each other in their common overlap region in the axial direction. Here, for example, on one of the two elements in the interior of the respective other element axially insertable sleeve can be arranged. According to a particularly advantageous proposal, an annular sleeve can be used as an additional element in corresponding end-side recesses of the hinge strap or the Bandklobens.

This design has the particular advantage that a height compensation during assembly of the hinge or Bandklobens can be realized. Both are basically independent of each other and only in the common coverage area in the axial direction by a corresponding Ring or sleeve member connected so that there is flexibility in the axial direction and thus takes place secured against access to the cable bushing height compensation. This training is particularly advantageous in connection with height-adjustable designed straps.

In a particularly advantageous manner, the band tab and the band clamp are formed at least in the common overlap region substantially with a C-shaped cross-section, so that there is a substantially cylindrical cable entry in the interior. Is used in this as proposed by the invention spiral-shaped ribbon cable, this is completely secured against damage due to Türverschwenkungen.

Due to the formation of open ends in the region of the top and the underside of hinge tabs and band clamps, the cable leadthrough area basically remains accessible, for example for repair purposes, supplementary purposes, checking purposes and the like. The open ends of the cable feed area can be made lockable by means of suitable cover caps.

Another particular advantage of this embodiment results from the possibility that hinge tabs and band clamps can be used in different coverage order both on the left and on the right side of a door as a fitting.

The invention provides a constructed from a few elements, with respect to pre-assembly and assembly extremely simple, damage-unacceptable and against unauthorized access and sabotage very safe door hinge assembly ready, which meets both the mechanical requirements in security areas as well as electrification in the door area in the simplest way possible. The number of required components is reduced to a minimum and it is no longer necessary during installation of the door cable pulling in the fitting area.

1 shows a door hinge assembly 1. On-site, a cable feed is provided up to the region of a frame 2. This is to be performed in the door leaf 3, for example, to an electrical locking system. For this purpose, designed Bandkloben 4 and hinge tabs 5 are arranged in the manner of a hinge. The door hinge assembly 1 can be used exclusively for cable entry as a hinge dummy, so that it requires additional, similarly designed supporting hinge elements or door hinge assemblies. For lightweight door leaves or corresponding on-site conditions, however, a door hinge assembly 1 according to the embodiment shown can also take on supporting forces.

For the purpose of cable entry a predetermined in their dimensions recess 13, a so-called Zargenausbruch is formed in the frame. For the cable routing an outbreak 14 is correspondingly formed in the door leaf 3. In the embodiment shown mounting plates 15 are fixed to the frame 2 and 16 on the door leaf 3 by means of screws in the outbreaks. In the mounting plates in turn line interfaces 17 and 18 are mounted. At the line interfaces 17 and 18, the on-site or door leaf side laid lines are connected. The mounting plates 15 and 16 wear mounting lugs 19 and 20, which serve for fastening the Bandklobens by means of fastening screws 6 on the mounting lugs 19 on the one hand, and the attachment of the hinge strap 5 by means of fastening screws 7 to the mounting lugs 20. The fastening screws 6 and 7 can be sealed for safety reasons or drilled out against tool attack.

The Fign. 3 and 4 show in detail embodiments for mounting plates 15, 16. The mounting plate 15, which is mounted on the frame side and provided for fastening the Bandklobens, has the mounting lugs 19 for fixing the Bandklobens and an interface receptacle 21. Holes 22 serve on the one hand for mounting the Interface to the mounting plate, on the other hand, the attachment of the mounting plate on the frame. The mounting plate 16 has corresponding to an interface receptacle 23, mounting lugs 20 for fastening the hinge strap and holes 24 for fixing the plate on the door leaf and for mounting the interface to the mounting plate.

As is apparent from Fig. 5, the total assembly includes only a manageable number of items. To an on-site advanced line, which protrudes through a not shown outbreak from a frame, the interface element 17 is connected. This is then mounted by means of threaded plates 13 and Blechschraubelementen 31 on the base plate 15. The base plate 15 is then in turn secured using the tapping screws 34 to the frame. Door side, not shown inside the door leaf lines are laid, which protrude from a door leaf breakout. These lines are connected to an interface element 18. The interface element 18 is in turn secured by means of threaded plates 32 to the base plate 16. In the embodiment shown, the interface element 18 is a plug, the frame-side interface element 17 is a socket. Both project through corresponding recesses 21 and 23 from the respective base plates connectable. The base plate 16 is then in turn secured by means of self-tapping screws 35 on the door leaf. On the fitting side the respectively suitable interface elements are used. On the side of the band clamp, a plug 36 is used. This is to a not shown Ribbon cable connected. The ribbon cable is then inserted into the interior 25 of the band clamp 4 and led out of the band clamp using a helical twist through the opening 27. Now, the band clamp can be fixed to the frame using the fixing screws 6 which are fixed in the mounting lugs 19 on the base plate 15. To prevent inadvertent engagement, sabotage or the like, the screw heads 6 can be sealed or drilled round against tool attack. The ribbon cable is then guided while maintaining a spiral twist through the cylindrical cavity 28 of the hinge strap 5 and there in the hinge flap cavity 26. At this point, the interface element 37, in the illustrated embodiment, a socket, connected to the ribbon cable. Since the interface element 36 is inserted into the interface element 17 and the interface element 37 to the interface element 18, the electrical line is closed. By means of screws 7, the hinge tab is fixed by screwing into the mounting lugs 20 on the base plate 16. Between Bandkloben 4 and hinge tabs 5, an intermediate ring 29 may be used, which is also penetrated by the spirally twisted ribbon cable and allows height compensation to adapt Bandkloben and hinge tabs to the respective Zargen- or door-side recesses. The spiral arrangement of the flat cable has the advantage that the individual wires of the cable are exposed to a slight relative movement or buckling, so that the risk of breakage compared to conventional cable arrangements is significantly reduced.

Obviously, it is readily possible to form from the band clamp 4, the intermediate ring 29 and the hinge flap 5 a preassembled unit which is guided by the ribbon cable in the passage region 27, the ring 29 and passage portion 28 from the terminal cavity 25 to the terminal cavity 26 in the hinge tab , The two interface elements 36 and 37 may already be attached and used for mounting on the ribbon cable. The cylindrical passage space 27, 28 is accessible through openings in the front edges of both the Bandklobens and the hinge strap and the openings are closed by caps 11.

The described embodiment is merely illustrative and not limiting. In particular, with respect to the interface elements, the shapes of hinge pins and hinge tabs are freely variable without departing from the scope of the invention as defined in the claims.
