Door safety system, method for operating a door safety system, and transport means

A door (2), in particular an automatic door (2) of a transport means (1) comprising:

• an immovable door frame (5) carried by the transport means (1);
• a movable door element (4, 4a, 4b) which comprises a door leaf, and the movable door element (4, 4a, 4b) is at least partially movably carried by the immovable door frame (5);
• and
• a door safety system (3) having,
• a safety component (10) arranged on the movable door element (4, 4a, 4b) of the door (2), and the safety component (10) has an electrical energy store (12), and wherein
• the safety component comprises at least one of a light barrier, a light curtain, a light grid, a contact safety strip, an optical signal generator, an acoustic signal generator, or a haptic signal generator;
• and
• a supply component (11) which is arranged on the immovable door frame (5) of the door (2) and the supply component supplies the safety component (10) with electricity, and wherein
• the electrical energy store (12) autonomously supplies the safety component (10) with electrical energy when the door (2) is in an open state relative to the immovable door frame (5), and wherein
• the safety component (10) and the supply component (11) electrically charge the electrical energy store (12) of the safety component (10) when the door (2) is in a closed state relative to the immovable door frame (5);
• and
• a controller (22) for controlling and/or monitoring the safety component (10);
• and
• the controller (22) is arranged on the immovable door frame (5);
• and wherein
• the safety component (10) and the controller (22) operatively communicate bidirectionally and wirelessly with one another.

A transport means (1), in particular an omnibus (1) or a rail vehicle comprising:

• at least one door (2), in particular an automatic door (2) of the transport means (1);
• an immovable door frame (5) carried by the transport means (1);
• a movable door element (4, 4a, 4b) which comprises a door leaf, and the movable door element (4, 4a, 4b) is at least partially movably carried by the immovable door frame (5);
• and
• a door safety system (3) having,
• a safety component (10) arranged on the movable door element (4, 4a, 4b) of the door (2), and the safety component (10) has an electrical energy store (12), and wherein
• the safety component comprises at least one of a light barrier, a light curtain a light grid, a contact safety strip, an optical signal generator, an acoustic signal generator, a haptic signal generator;
• and
• a supply component (11) which is arranged on the immovable door frame (5) of the door (2) and the supply component supplies the safety component (10) with electricity, and wherein
• the electrical energy store (12) autonomously supplies the safety component (10) with electrical energy when the door (2) is in an open state relative to the immovable door frame (5), and wherein
• the safety component (10) and the supply component (11) electrically charge the electrical energy store (12) of the safety component (10) when the door (2) is in a closed state relative to the immovable door frame (5);
• and
• a controller (22) for controlling and/or monitoring the safety component (10);
• and
• the controller (22) is arranged on the immovable door frame (5);
• and wherein
• the safety component (10) and the controller (22) operatively communicate bidirectionally and wirelessly with one another.

A method for operating a door safety system (3) of a door (2), the method comprising the steps:

• providing an immovable door frame (5) of the door (2);
• providing a movable door element (4, 4a, 4b) comprising a door leaf that is at least partially movable relative to the immovable door frame (5);
• providing a safety component (10) arranged on the movable door element (4, 4a, 4b);
• providing a supply component (11) arranged on the immovable door frame (5) of the door (2) to supply electricity to the safety component (10);
• and wherein
• the safety component comprises at least one of a light barrier, a light curtain, a light grid, a contact safety strip, an optical signal generator, an acoustic signal generator, or a haptic signal generator;
• and
• providing an electrical store (12) that autonomously supplies electrical energy to the safety component (10) when the door (2) is in an open state;
• and
• electrically charging the electrical store (12) by means of the supply component (11) when the door (2) is in a closed state;
• and
• providing a controller (22) for controlling and/or monitoring the safety component (10), and wherein the controller (22) is arranged on the immovable door frame (5), and wherein the safety component (10) and the controller (22) operatively communicate bidirectionally and wirelessly with one another.
