Description

The present invention relates to a hinge for the arrangement between a wing and a frame with a first fastening means, a second fastening means, at least one hinge bracket which connects the first fastening means and the second fastening means and is rotatably received by the first fastening means, and with an electric Line between the two fastening devices.

The invention further relates to a door assembly with a door leaf, a door frame and a door hinge.

A hinge in the form of a door hinge is from the EP 1 489 255 B1 known. The electrical line is guided through holes in mounting flanges of the fastening device and allows an electrical power supply from the door frame to the door to provide power consumers on the door panel as inconspicuous as possible through the door hinge with power. In the closed state of the door, the electrical line is indeed covered and protected, but the opening movement of the door leaf, the electrical line is visible and thus prone to negligent or intentional damage. In particular, there is also the risk that the electric cable is crushed when opening and closing the door between parts of the door hinge. An additionally provided protective line should prevent this. As a result, complex constructive measures are necessary to move the electrical line draft-free and safe. Since the length of the electrical line between the two fastening devices changes during the opening movement, this is only loose and movable used. Finally, the visual appearance is also affected by the additional, visible electrical line.

From the DE 10 2007 041 816 B4 Another generic door hinge with an electrical line is known, wherein the electrical line is concealed behind a concealed door hinge with two cooperating hinge brackets behind the hinge brackets. The electrical line is also laid freely between the two fasteners and is angled several times. The protection against damage by the movement or by a user is still in need of improvement. Again, the electric cable is used loosely movable, with free ends of the electrical cable with connectors on the back of the fasteners protrude.

According to the DE 10 2007 041 816 B4 is provided as an electrical line a ribbon cable. This results in the advantage that several wires can be provided isolated from each other in a ribbon cable readily. It can thus be realized with several power and electronic control circuits, in some cases considerable requirements must be considered. As electrical devices of a door, for example, fingerprint sensors, electrical locks and locking mechanisms, lighting, display displays, electronic controls or the like come into consideration.

In addition to the from the DE 10 2007 041 816 B4 and EP 1 489 255 B1 known generic door hinges or door hinges are also known other hinge structures with an electrical line. So revealed the EP 0 464 768 B1 a hinge construction in which an electric wire is wound around a pivot axis.

From the EP 1 023 753 B1 Furthermore, a hinge for electronic devices is known in which a ribbon cable is guided as an electrical line through a separate, rotatable sleeve.

The US 2005/0091797 A1 describes a special band construction in which two hinge tabs are rotatable about a toothing. Such a hinge construction does without a hinged hinge bracket and is only suitable for very flat plate-shaped parts. Such a hinge construction can not be used for doors in which a door should move away from a frame, especially when the door and frame are provided according to the usual embodiments with folds and / or seals. An electrical line, in particular a ribbon cable is to be guided around the joint formed by the toothing.

A hinge for a refrigerator and / or freezer with the features described above is known from DE 20 2007 008 106 U1 known. An electrical lead is routed to the top of a hinge bracket assembly. With regard to the protection of the electrical line from damage and dirt, the described embodiment is still in need of improvement.

From the DE 20 2005 018 419 U1 a door hinge with an electrical line is known, wherein the electrical line is placed exactly through the pivot axes and so no length change is subjected. However, the electrical line must be able to accommodate torsional loads.

The present invention has for its object to provide a generic hinge for the arrangement between a wing and a frame, in which an electrical line is particularly well protected against damage and wear. Furthermore, the hinge should also be easy to install. Finally, a door assembly should be specified with such a door hinge.

The object of the invention and solution of the problem are a door hinge according to claim 1 and a door assembly according to claim 6.

Since the electric wire is inserted into the hinge bracket and / or fixed to the hinge bracket, the hinge bracket and the electric wire form a unit with respect to the movement of the door hinge. Consequently, the electrical line does not move, or at most little, with respect to the hinge stirrup, so that along with the hinge stirrup, even in the case of long-term operation, no stresses that impair the function of the electrical line can occur.

The necessary for the operation of the door hinge mobility of the electrical line is thereby provided by the supply in the form of a loop or spiral, which is formed on the first fastening means. The movement of the electrical line is thus kept away from the hinge bracket itself and moved to a well-defined area, namely the stock. The supply can be designed by a spiral shape or a loop so that there the electrical line takes no damage even with a long-term use of the door hinge.

The electrical line and the hinge bracket are immovably arranged on the second fastening device. The electrical line and the hinge bracket can be clamped or screwed, for example, to the second fastening device.

As explained above, there is the supply of the first fastening device, which allows the necessary mobility of the electrical line. In order to enable a reliable and simple contacting even at the first fastening device, an electrical connection is fixed there, wherein the supply of the first fastening device between the electrical connection and the hinge bracket is formed. The length, arrangement and mobility of the stock are so well defined. The supply can be adjusted so that under all circumstances damage to the electrical line is prevented. Tensile forces on the leads to the door hinge can not be transferred to the electrical line. It is also advantageous that precisely defined and reproducible conditions for the movement of the electrical line are ensured by the formation of the stock between the electrical connection and the hinge bracket.

In order to integrate the electrical line in the hinge bracket, the hinge bracket may have a groove. This groove preferably extends at least the length of the hinge bracket, which is exposed in the use of the hinge in the gap between the wing and frame. When the electric wire is inserted into a groove of the hinge bracket, the recessed arrangement in the groove provides improved protection. In addition, a cover may also be provided, which is arranged on the electrical line and closes the groove. The electrical line is then no longer visible and optimally protected against damage and manipulation. Depending on the design of the hinge, it is not obvious to a user where and how the electrical connection of the wing takes place.

The concealed arrangement of the electrical line within the hinge bracket or a groove of the hinge bracket can also be advantageous for safety reasons, for example, to achieve protection against manipulation. Such protection may be of particular importance when the door is equipped with safety devices connected via the electrical line.

In principle, different variants come into consideration in order to arrange the electrical line hidden on the hinge bracket. Thus, the hinge bracket may consist of several parts which receive the electrical line inside. An embodiment with groove and cover is merely one possible concrete embodiment of this approach. In a plastic hinge bracket, the electrical line can be embedded, for example, directly in an injection molding in the material of the hinge bracket.

As described above, there are particular advantages when the electrical line is inserted into the hinge bracket. A movement of the electrical line relative to the hinge bracket can additionally or alternatively also be avoided in that the electrical line is fastened to the hinge bracket, for example glued to the hinge bracket.

According to a preferred embodiment of the invention it is provided that the hinge bracket for a concealed arrangement between the wing and frame has a curved and / or angled shape. Basically, it is possible to integrate the electrical line in one of two pairwise cooperating hinge straps, as these from the DE 10 2007 041 816 B4 as well as the EP 1 489 255 B1 are known.

According to a particularly preferred embodiment of the invention, but the two fastening devices are connected only by a hinge bracket with each other, which allows the hidden arrangement between the frame and wing by a curved and / or angled shape. For example, in a plan view, the hinge bracket may have an approximately V- or U-shaped configuration. A door hinge with a correspondingly shaped hinge bracket is made of DE 10 2010 012 691 B3 known.

As explained below, the door hinge in question can also be used in addition to other door hinges, wherein the weight of the door leaf is supported at least substantially over the door hinges. The door hinge then serves only to allow an electrical supply of the door leaf. If in the context of such an embodiment, the door hinge according to the invention has no supporting properties, the hinge bracket can be plugged in a particularly simple manner with a straight end portion in a receiving slot of the second fastening part. It then results in a immovable arrangement on the second fastening part without a strong fixation. Alternatively, the arrangement of a straight end portion of the hinge bracket in the receiving slot can also be used to a clamping attachment, in which case a appropriate clamping mechanism or another type of attachment is provided.

The electrical lead may terminate at the second fastener in a plug to facilitate easy contacting. At the second fastening device then a corresponding counterpart for the plug is provided.

As electrical line, a ribbon cable is provided which has a plurality of wires and is characterized by a certain mobility. The supply can be provided in the form of a simple loop, which shortens reproducibly upon opening of the door hinge. Furthermore, the supply may also have a spiral shape. The beginning and the end of such a spiral are then outboard, in which case the electrical line, so preferably a ribbon cable, double-layered is wound in a spiral shape and lying inside the two wound layers merge into each other. If a suitable ribbon cable is used, an automatic winding function can be realized solely from the elastic restoring force of the material. In addition, spring-loaded return mechanisms or the like are conceivable.

The invention also relates to a door assembly with a door leaf, a door frame and the door hinge described above, wherein the electrical line is preferably completely covered with an open door, for example, behind a cover arranged.

The door hinge is not visible in a closed door according to a preferred embodiment, wherein the door hinge is used with the fasteners in narrow sides of the door leaf and door frame.

As already explained above, two door hinges can be arranged between the door leaf and door frame in addition to the door hinge, wherein the force support of the door leaf on the door frame takes place exclusively or at least essentially via the door hinges. This results in an arrangement with three connecting elements in the form of the two hinges and the door hinge, which can be optically matched. For a user, this may give the impression that the three elements have the same design, but the door hinge, which is preferably arranged in the middle, serves only or essentially only the electrical connection of the door leaf.

a schematic view of the entire door assembly.

The Fig. 1 1 shows a door arrangement with a door leaf 1, a door frame 2 and a door hinge 3 between door leaf 1 and door frame 2. The door hinge 3 is inserted into the door frame 2 with a first fastening device 4 and into the door leaf 1 with a second fastening device 5, wherein the two fastening means 4, 5 are interconnected by a hinge bracket 6. The hinge bracket 6 extends at its ends in the two fastening devices 4, 5. In the Fig. 1 it can already be seen that the hinge bracket 6 is provided in a central region with a separate cover 7, which covers an underlying groove 8 of the hinge bracket 6.

Further details of the door hinge arise from the cross section according to the Fig. 2 , The hinge bracket 6 is rotatably received on a pivot axis 9 on the first fastening device 4. In addition, it can be seen that in the groove 8 below the cover 7, an electrical line 10 extends, which connects the two fasteners 4, 5 together. Through the groove 8 and the cover 7, a channel is formed for the electrical line 10 in the form of a ribbon cable, with which the electrical line 10 is concealed out of the hinge bracket 6 and held. The electrical lead 10 terminates at the second attachment means 5 with a plug 11, where also the hinge bracket 6 is arranged with a straight end portion 12 in a receiving slot 13 of the second fastening part 5.

If the hinge bracket 6 is provided for a power transmission between the door leaf 1 and door frame 2, a firm clamping of the straight end portion 12 can be made to the receiving slot 13, but in principle, other types of attachment of the hinge bracket 6 to the second fastening device 5 are possible.

Usually, however, it is always provided that the hinge bracket 6 and the electrical line 10 are immovably arranged in the mounted state on the second fastening device 5. Similarly, the second fastening means 5, the hinge bracket 6 and arranged in this area portion of the electrical line 10 form a rigid unit in which the said parts do not move against each other.

The opening movement of the door leaf 1 results in this context in that the door leaf 1 rotates with the second fastening device 5, the hinge bracket 6 and the associated portion of the electrical line 10 relative to the door frame 2 about the pivot axis 9. The run in the groove 8 section of the electric wire 10 is thus kept free of movement and stress and is therefore not at risk of deterioration.

In addition, the electric wire 10 according to the Fig. 1 Even with an open door 1 completely protected and can not be manipulated or damaged. Even a buckling of the electrical line 10 between the door 1 and door frame 2 is completely excluded.

In order to enable the pivoting movement, the electrical line 10 at the first fastening device 4 on a supply 14 in the form of a loop. Since according to the present embodiment, the first fastening means 4 is inserted into the door frame 2 in the form of a hollow profile, and this supply 14 is optimally protected. According to the electrical line 10 is thus divided into an area along the hinge bracket 6 and the stock 14, wherein only on the stock a load by the opening and closing movement of the door leaf 1 occurs. This also results in the advantage that the type of load and the size of the stock 14 can be tailored to the particular application. According to the Fig. 2 is at the first fastening means 4, an electrical connection 15 is present, wherein the supply 14 is arranged with a defined length between the electrical connection 15 and the hinge bracket 6.

The Fig. 3 shows the door hinge 3 without door leaf 1 and door frame 2 in a view of the pivot axis 9 and the stock 14. It can be seen that the electrical connection 15 is designed as a board with plug connections. In order to fix the illustrated door hinge on the door leaf 1 and the door frame 2, the fastening means 4 and 5 each have a base body 16a, 16b.

The Fig. 4 shows starting from the Fig. 3 the door hinge 3 from an opposite side without the main body 16a, 16b. For clarity, the cover 7 is omitted, so that the course of the electrical line 10 in the groove 8 can be seen. Furthermore, the arrangement of the straight portion 12 of the hinge bracket 6 in the receiving slot 13 of the second fastening device 5 can be seen. The counterpart is also recognizable 17 to the plug 11 in which the electrical line 10 ends. The counterpart 17 is as an electrical device part of the second fastening device 5, which in turn a door leaf-side cable can be connected during assembly. The connection of door leaf 1 and door frame 2 can also be carried out particularly easily during assembly that the straight end portion 12 of the hinge bracket 6 is pushed into the associated groove and the plug 11 on the counterpart 17.

The Fig. 5 shows an otherwise identical embodiment, an alternative embodiment of the door hinge 3, but the supply 14 of the electrical line 10 is not designed as a loop but as a kind of spiral. The ends of the spiral lie outside, in which case the electrical line 10 is double-layered wound inwards and wherein at the inner end of the spiral, the two layers merge into one another. In a suitable embodiment of the electrical line 10 in the form of a ribbon cable, the supply 14 can be prefabricated in the form of a spiral, which results in a reproducible up and unwinding solely due to the restoring forces of the spiral.

The Fig. 6 shows an entire door assembly in which the described door hinge 3 is arranged approximately centrally in the vertical direction of the door leaf 1, wherein above and below the door hinge 3 additional door hinges 18 are arranged. The door hinges 18 are equipped without an electrical line 10 and serve to support the weight of the door leaf 1 on the door frame 2. In the context of such an embodiment, it is possible that the door hinge 3 itself transmits no or only a small force and is provided as a kind of dummy door hinge only for the electrical connection.
