Abstract: A door arrangement (1), includes a safety device. A door arrangement monitoring method monitors a monitored area positioned in front of a door opening, offset and parallel to a door closing plane, and performs a failure routine when an object (6) is detected in the monitored area and there is a risk of a collision of the object (6) with a door leaf (2). A current position of the object (6), and of a leading edge (23) of the door leaf (2), are detected. A direction of movement of the door leaf (2) is detected. The failure routine is initiated as a function of the current position of the object (6) and the leading edge (23) of the door leaf (2) as well as the direction of movement of the door leaf (2).

Abstract: A door, in particular a high-speed industrial door, with an intelligent door leaf is disclosed. The door has a door leaf which is guided by lateral guides and covers a door opening, and which has a first and a second side, a driving means for moving the door leaf between an open and a closed position, a door control means for controlling the driving means, as well as an electrically self-sufficient door leaf means arranged in the door leaf. The door control means also has a first communication unit. In addition, the door leaf device comprises at least one sensor unit for detecting at least a physical quantity, an energy converter which converts non-electrical energy into electrical energy, a second communication unit and at least one actuator unit. The first and second communication units communicate wirelessly with each other.

Abstract: The invention relates to a device (100) for detecting the falling of a door leaf (2) of a door (1), preferably a high-speed industrial door (1), the device (100) for detecting the falling of a door leaf being provided on or in the door leaf (2). The device (100) for detecting the falling of a door leaf comprises a means for detecting the acceleration of said device (100) in at least one falling direction of the device (100), and a wireless communication unit (200) for emitting a falling warning signal in the event of a falling of the door leaf (2) being positively detected. The positive detection of the falling of the door leaf (2) is based on an acceleration being detected in the falling direction.

Abstract: A high-speed industrial door includes a door leaf having a plurality of stiffening profiles and a flexible curtain. Each stiffening profile extends crosswise relative to a lateral passing over the door leaf and connects two hinge elements assigned to one another. A flexible curtain is fixed to each stiffening profile. This makes it possible to provide a high-speed industrial door that can be operated at speeds faster than 3 m/s while involving little engineering complexity and low costs.

Abstract: The invention relates to a device for automatically actuating a door, in particular a vertical door, which aims to replace to a great extent known signal generation devices or control signal sensors for opening the door or for the security monitoring of the closing motion of the door. This is achieved by a detector of a security system, which is configured as a scanner detector and operates according to reflective principles, for monitoring an area by allocation to one of the ground level aprons of the door, said detector being mounted in the vicinity of a lateral border of the door opening, at a height, which is adjusted to the maximum height of objects supported on the relevant apron that are not to be registered as obstacles. The scanning beam of said detector scans a horizontal fan-shaped area, which covers the relevant apron and has a low vertical depth, determined by the depth of the scanning beam, as the monitoring area.

Abstract: An industrial gate having a gate body covering the gateway and comprising a multiplicity of segments (21) which are interconnected such that they may be oriented at a relative angle and which are formed to be double-walled, wherein the segment walls (211, 212) are interconnected at their longitudinal edges through the intermediary of a respective web (213), which web is formed of a material having a lower heat conductivity than the material of the segment walls (211, 212) so as to establish a thermal separation of the segment walls (211, 212). To this end, one substantially U-shaped profile groove (2111, 2121) each for receiving the edges of the webs (213) is formed at the longitudinal edges of the segment walls (211, 212), and one elastomer plastic element (214) each is arranged between the edges of the webs (213) and the inner surface of the profile groove (2111, 2121) in a press-fit, i.e., under deformation of the plastic element (214) in comparison with the load-free state.

Abstract: A gate arrangement for closure of a passageway between rooms with markedly different temperatures, such as the passageway of a freezer-room. Two door curtains are arranged parallel to one another, with each being capable of closing the passageway independently of the other. The door curtains have an abutting insulating air buffer between them, wherein at least one of the door curtains can be motor-driven at such a speed that it is suitable as a temporary high-speed closure between successive passages or transits therethrough. The two door curtains together with the insulating air buffer develop the insulation effect required to maintain the desired cooling temperature. Thus, frequent stocking of the room is possible while compromise of the climate in such rooms during stocking operations is kept to the minimum possible.

The segments (21) comprise two profile members (211, 212) extending over the length of the segments (21) and an insert panel (213) which is arranged between these and optionally is translucent, wherein the profile members (211, 212) each have a substantially U-shaped profile groove for receiving the longitudinal edges of the insert panel (213), and wherein one respective elastomer plastic element (214, 215) each is arranged between the longitudinal edges of the insert panel (213) and the inner surface of the profile groove in a press-fit, i.e., under deformation of the plastic element (214, 215) in comparison with the load-free state. The industrial gate in accordance with the invention is characterized in that the gate body—while maintaining the suitability for an external closure as known, e.g.

Abstract: A safety device for externally driven systems for protecting the movement of a system component against undesired collision with an object lying in the movement path of the system component is described, the system component to be monitored being capable of being moved in a guided fashion along a predetermined path (door plane ET). The movement path of a leading edge of a system component is preferably monitored by an optical beam protection, preferably on the basis of infrared beams, which protection has at least two, preferably at least three or a plurality of preferably parallel beams which are arranged staggered in the direction of movement of the system component and which are emitted on one side of the system component and received or reflected on the other side. The safety device has a safety circuit with which the movement of the system component is stopped or reversed if an obstacle is sensed in the movement path of the system component.
