A passage barrier includes two guide elements that cooperate such that they define a gate region, through which a person passes from an entrance region into a passage region. At least one of the guide elements includes a vertically running profile, on which a locking apparatus is arranged. The locking apparatus has a torque transmission toothing, which engages into a complementary torque reception toothing of a hollow shaft of a drive. A circular stop disc is also provided and has a toothing engagement, which is engaged with the torque transmission toothing. The stop disc has a circumferential surface with a stop lug, which protrudes radially from the stop disc circumferential surface, and cooperates with a stop element arranged on the vertically running profile such that a rotation of the stop disc is delimited by the engagement of the stop lug against the stop element.

A passage barrier includes two guide elements that define a gate region, through which a person passes from an entrance region into a passage region. At least one barrier element prevents and/or enables the passage of the person from the entrance region into the passage region within the gate region. At least one of the guide elements includes a profile attachment element for attaching at least one profile of a guide element to the base of a building structure. The profile attachment element has a vertical profile mount for mounting a vertically running profile on the profile attachment element and a horizontal profile feedthrough for feeding a horizontally running profile through the profile attachment element.

A system, method and computer program product for controlling the operation of a door (1) to a room, the method comprising (S1) obtaining at least a first air pressure data (1ap) based on an air pressure on the inside of the door (1), (S2) obtaining at least a second air pressure data (2ap) based on the air pressure on the outside of the door (1), and (S5) determining at least a first air pressure difference data (1apdd) based on the difference between the at least first air pressure data (1ap) and the at least second air pressure data (2ap), and in a determination that the at least first air pressure difference data (1apdd) is outside of a predefined value, or a predefined value interval, generate a control signal (CS) for controlling the operation of the door (1).

An air-tight door system and a control method therefor. The air-tight door comprises a first door (M1), a second door (M2), a first door detection module (S1, S2, P1), a second door detection module (S3, S4, P2) and a controller (K). The air-tight door control method comprises: the first and second detection modules (S1, S2, P1, S3, S4, P2) detect whether the first door (M1) and the second door (M2) are completely closed; and the controller (K) controls opening and closing of the first door (M1) and the second door (M2) according to whether the first and second doors (M1, M2) are completely closed. The air-tight door system and the control method therefor ensure that at least one door is in the closed state at any time, thereby further improving air-tightness and device safety.

A passage barrier includes a first guide element and a second guide element, wherein the first guide element and the second guide element define a gate region, through which a person passes from an entrance region into a passage region. At least one barrier element can prevent and/or enable the passage of a person from the entrance region into the passage region within the gate region. At least one of the guide elements includes a profile attachment element for attaching at least one profile of a guide element to the base of a building structure, wherein the profile attachment element has a vertical profile mount for mounting a vertically running profile on the profile attachment element and the profile attachment element has a horizontal profile feedthrough for feeding a horizontally running profile through the profile attachment element.

A passage barrier has guide elements, the first guide element and the second guide element cooperate such that they define a gate region, through which a person passes from an entrance region into a passage region. At least one guide element includes a vertically running profile, on which a locking apparatus is arranged. The locking apparatus has a torque transmission toothing, which engages into a complementary torque reception toothing of the hollow shaft, wherein a circular stop disc is disposed, which has a toothing engagement, which is engaged with the torque transmission toothing. The stop disc has on its stop disc circumferential surface a stop lug, which protrudes radially from the stop disc circumferential surface, and cooperates with a stop element arranged on the vertically running profile such that a rotation of the stop disc is delimited by the stopping of the stop lug against the stop element.

A gate safety system for preventing collisions between a vehicle and a gate is provided, the system having a gate module with a vehicle module, a gate antenna unit and a gate processing unit. The gate processing unit is adapted for defining a first gate warning zone and for determining whether a vehicle module is present within the first gate warning zone. The vehicle module includes a vehicle antenna unit and a vehicle processing unit adapted for defining at least one first vehicle warning zone for determining whether the gate module is present within the vehicle warning zone. A lock safety system, two methods for operating the gate safety system and the lock safety system, and two computer programs are also provided.

An axis positioning mechanism serving as a rotation bearing of a flap gate includes a housing disposed at the bottom of an opening, a first rotating plate rotationally supported by the housing via a first shaft, a second rotating plate rotationally supported by the housing via a second shaft having a different axis from the first shaft, and a synchronizing rod rotationally connected to the rotating plates so as to synchronize the rotations of the rotating plates. The axis positioning mechanism further includes connecting members rotationally connecting a door base and the rotating plates with different axes. The door is laid flat with a pivot at a higher position than the axes.
