An overhead folding system, overhead folding door in particular, which can be installed in or on a building wall with a building opening which is spanned by a lintel, which can be installed in particular with or in a frame comprising laterally arranged frame side parts, and which is suitable, by means of a drive device of the overhead folding system, which comprises a drive shaft, for being opened by lifting the overhead folding system and for being closed by lowering the overhead folding system, it being possible to fasten the drive device to the building opening, particularly to the lintel or in the region of the lintel, the overhead folding system comprising a pair of panels (2, 3), which has a bottom-side bottom panel and also a lintel-side lintel panel, which is rotatably connected to the bottom panel by a panel hinge joint and is rotatably mounted to a lintel-side lintel joint in the region of the lintel, it being possible to arrange the bottom panel and lintel panel in a system plane when the overhead folding system is lowered and adjacently V-shaped with respect to one another and outside the system plane when the overhead folding system is open, the lifting and lowering of the overhead folding system taking place by means of at least one pulling element, which is fastened to the bottom panel, particularly close to the ground, and can be moved by means of the drive shaft, at least one locking device being provided, using which the overhead folding system and/or the lintel panel and/or the bottom panel and/or the pulling element can be locked in the closed position, the locking device being lockable or unlockable by means of the drive device, by means of a lock driver connected to the drive device, the unlocking of the locking device taking place before the lifting of the overhead folding system and the locking of the locking device taking place after the lowering of the overhead folding system, and the drive device comprising at least one drive bracket, which is preferably arranged between the frame side parts or laterally on or next to a frame side part, on which drive bracket the drive shaft is rotatably arranged, a guide element, which is in particular formed as a roller or reel, for guiding the pulling element (10, 34) and/or the lock driver being arranged on the drive bracket, and the guide element being coupled to the drive shaft, characterized in that the locking device comprises at least one locking element, which is formed as a claw or hook or pincers, which mechanically interacts with a lock receptacle arranged in and/or on the ground in the region of the centre of the panel between the frame side parts, in that the lock receptacle is formed as a recess with a rod assembly for engaging behind the claw or the hook or for engaging the pincers, and in that an auxiliary pulling element is provided, which mechanically supports the pulling element, wherein the auxiliary pulling element comprises the lock driver for actuating the locking device. it being possible to fasten the drive device to the building opening, particularly to the lintel or in the region of the lintel, the overhead folding system comprising a pair of panels (2, 3), which has a bottom-side bottom panel and also a lintel-side lintel panel, which is rotatably connected to the bottom panel by a panel hinge joint and is rotatably mounted to a lintel-side lintel joint in the region of the lintel, it being possible to arrange the bottom panel and lintel panel in a system plane when the overhead folding system is lowered and adjacently V-shaped with respect to one another and outside the system plane when the overhead folding system is open, the lifting and lowering of the overhead folding system taking place by means of at least one pulling element, which is fastened to the bottom panel, particularly close to the ground, and can be moved by means of the drive shaft, at least one locking device being provided, using which the overhead folding system and/or the lintel panel and/or the bottom panel and/or the pulling element can be locked in the closed position, the locking device being lockable or unlockable by means of the drive device, by means of a lock driver connected to the drive device, the unlocking of the locking device taking place before the lifting of the overhead folding system and the locking of the locking device taking place after the lowering of the overhead folding system, and the drive device comprising at least one drive bracket, which is preferably arranged between the frame side parts or laterally on or next to a frame side part, on which drive bracket the drive shaft is rotatably arranged, a guide element, which is in particular formed as a roller or reel, for guiding the pulling element (10, 34) and/or the lock driver being arranged on the drive bracket, and the guide element being coupled to the drive shaft, characterized in that the locking device comprises at least one
