Door handle system for a safety door, especially for a sliding door or a swing door

A door handle system for a safety door, comprises the following features:

• a bolt unit is provided, wherein the bolt unit comprises a housing with a bolt opening, and a handle, wherein the handle is arranged at the housing:
• the bolt unit comprises a frame structure with a bolt, wherein the frame structure is arranged in the housing and wherein the frame structure is moveable with respect to the housing;
• the frame structure encloses a receiving room;
• the bolt is arranged at a first side of the frame structure, wherein a second side and a third side of the frame structure are arranged opposite to each other;
• the second side and the third side each comprise a gear rack directed to the receiving room, so that the gear racks of the second side and third side face each other;
• the bolt unit comprises a gear which is arranged within the receiving room;
• the handle is attached to the gear so that pressing the handle trans-lates into a rotation of the gear:
• upon rotation of the gear from a starting position to an end position, the gear is configured to get into contact with the corresponding gear rack, causing the frame structure to be displaced from a first position into a second position in relation to the housing thereby pushing the bolt out of the bolt opening,
• wherein the gear in form of a sector gear comprises a plurality of teeth,
• wherein the first tooth is in contact with the gear rack of the second side when the sector gear is in the starting position and wherein the last tooth is in contact with the gear rack of the third side when the sector gear is in the starting position, and
• wherein the first and the last tooth are smaller than the teeth of the sector gear in between.
