Apparatus for contactless transmission of electrical energy between a wall and a door leaf/window sash fastened to said wall

A hinge bolt which can be configured to serve as a magnetic flux conduction body between a primary coil and a secondary coil, the hinge bolt comprising:

• at least one flux element provided as a prefabricated structural component, the at least one flux element comprising at least one frontal side;
• at least one bearing piece comprising a mating frontal side;
• and
• a tensile element which is configured to pass through the at least one flux element and to be connected to the at least one bearing piece,
• wherein,
• the at least one frontal side of the at least one flux element is configured to brace against the mating frontal side of the at least one bearing piece,
• the tensile element is screwed to the at least one bearing piece,
• the at least one bearing piece is provided as a first bearing piece and a second bearing piece,
• the first bearing piece and the second bearing piece each being an end piece, and
• the tensile element is screwed to the first bearing piece and to the second bearing piece.

An apparatus for a contactless transmission of electrical energy between a wall and a door leaf/window sash fastened to the wall in an articulated fashion via hinges about a hinge axis, the apparatus comprising:

• a primary coil configured to be fastened to the wall;
• a secondary coil configured to be fastened to the door leaf/window sash;
• a hinge bolt configurable as a magnetic flux conduction body between the primary coil and the secondary coil, the hinge bolt comprising:
• at least one flux element provided as a prefabricated structural component, the at least one flux element comprising at least one frontal side;
• and
• at least one bearing piece comprising a mating frontal side,
• wherein, the at least one frontal side of the at least one flux element is configured to brace against the mating frontal side of the at least one bearing piece;
• and
• a center piece comprising a first mating frontal side and a second mating frontal side which are oriented away from each other,
• wherein,
• the at least one flux element is provided as a first flux element and a second flux element, the first flux element and the second flux element being disposed at a distance relative to each other and being spaced via the center piece, and
• the center piece has a shock-absorbing property.
