Abstract

A hinge plate for connecting a leaf of a door to a frame includes a frame hinge plate part comprising a frame fastening part and a frame hinge part. A leaf or sash hinge plate part comprises a leaf or sash fastening part and a leaf or sash hinge part. A primary coil is disposed in the frame hinge part and a secondary coil is disposed in the leaf or sash hinge part, each being configured to surround a hinge plate pin defining a hinge axis. The hinge plate pin is provided as a core for both the primary coil and the secondary coil and is configured to conduct magnetic flux lines. The hinge plate pin comprises a support element configured to transmit a mechanical force between the leaf and the frame. A flux element is configured to conduct the magnetic flux lines between the primary coil and the secondary coil.

Claims

1-15. -15. (canceled)

16. A hinge plate for connecting a leaf of a door or a sash of a window or the like to a frame so as to be hinged about a hinge axis, the hinge plate comprising:

a frame hinge plate part configured to be fastened to the frame, the frame hinge plate part comprising a frame fastening part and a frame hinge part;

a leaf or sash hinge plate part configured to be fastened to the leaf or sash, the leaf or sash hinge plate part comprising a leaf or sash fastening part and a leaf or sash hinge part; and

a primary coil disposed in the frame hinge part and a secondary coil disposed in the leaf or sash hinge part, the primary coil and the secondary coil each being configured to surround a hinge plate pin defining the hinge axis;

wherein

the hinge plate pin is provided as a core for both the primary coil and the secondary coil and is configured to conduct magnetic flux lines, and

the hinge plate pin comprises a support element configured to transmit a mechanical force between the leaf or sash and the frame, and a flux element configured to conduct the magnetic flux lines between the primary coil and the secondary coil.

17. The hinge plate as recited in claim 16, wherein the flux element comprises a material having ferromagnetic properties which can be processed in a flowable state.

18. The hinge plate as recited in claim 17, wherein the flux element is produced from a sinterable powder material.

19. The hinge plate as recited in claim 17, wherein the flux element comprises a mixture of ferromagnetic particles and a plastics material which can be solidified or which solidifies itself.

20. The hinge plate as recited in claim 19, wherein the plastics material is a thermoplastic material.

21. The hinge plate as recited in claim 19, wherein the plastics material is a multi-component material.

22. The hinge plate as recited in claim 19, wherein the plastics material has a friction-reducing property.

23. The hinge plate as recited in claim 16, wherein the support element is an elongated component provided as a mechanically stable material, and the flux element is a component fixedly connected to the support element which at least partially covers a lateral surface of the flux element.

24. The hinge plate as recited in claim 23, wherein the support element comprises at least one channel running obliquely with respect to the hinge axis, the at least one channel being filled with a material having ferromagnetic properties.

25. The hinge plate as recited in claim 23, wherein the flux element completely surrounds the support element.

26. The hinge plate as recited in claim 23, further comprising a cage which at least partially surrounds the flux element.

27. The hinge plate as recited in claim 26, wherein the cage consists of a material having a friction-reducing property.

28. The hinge plate as recited in claim 16, wherein the support element comprises a central volume extending in a direction of the hinge axis, the central volume being filled with a material having ferromagnetic properties.

29. The hinge plate as recited in claim 28, further comprising at least one channel filled with a material having ferromagnetic properties, the at least one channel extending transversely with respect to to the hinge axis from the central volume to a lateral surface of the support element.

30. A hinge plate for connecting a leaf of a door or a sash of a window or the like to a frame so as to be hinged about a hinge axis, the hinge plate comprising:

a frame hinge plate part configured to be fastened to the frame, the frame hinge plate part comprising a frame fastening part and a frame hinge part;

a leaf or sash hinge plate part configured to be fastened to the leaf or sash, the leaf or sash hinge plate part comprising a leaf or sash fastening part and a leaf or sash hinge part; and

a primary coil disposed in the frame hinge part and a secondary coil disposed in the leaf or sash hinge part, the primary coil and the secondary coil each being configured to surround a hinge plate pin defining the hinge axis;

wherein

the hinge plate pin is provided as a core for both the primary coil and the secondary coil and is configured to conduct magnetic flux lines,

the hinge plate pin comprises a support element configured to transmit a mechanical force between the leaf or sash and the frame, and a flux element configured to conduct the magnetic flux lines between the primary coil and the secondary coil, and

at least one of the primary coil and the secondary coil comprises contact elements disposed on an end face, the contact elements being configured to interact with mating contact elements disposed on a side of a connecting element facing the end face.
