Definitions

  • the invention relates to a revolving door driven by an electric motor with a safety circuit according to the preamble of claim 1.
  • a safety circuit for electromotive-driven and electrically brakeable or lockable flywheel has become known from DE-PS 39 34 662, which consists of strip-shaped touch or pressure-sensitive electrical switching elements. Special control units or monitoring units are intended to rule out any danger to the user.
  • DE-OS 30 20 483 in connection with a brochure from the Besam company shows a sensor strip which is fastened to a door on a cross bar.
  • This sensor strip works according to the photoelectric principle and detects objects in its radiation area.
  • the disadvantage of photoelectric sensors, however, is that they also e.g. Identify sheets of paper as an object and thus control the door according to the hazard functions.
  • the object of the invention is to secure a rotating wing of a revolving door in such a way that all moments of danger for the users of the traffic are excluded. At the same time, it should also be ensured that e.g. paper on the floor must not impair the functions of the revolving door.
  • the sensitivity of the vertical and horizontal sensors can be operated in two ways. In static operation, ie the sensors have the same sensitivity for the entire rotation of the rotary sash, each object is reliably recognized with the same sensitivity both on the floor and in the area of the crushing and shearing points. If, however, an even higher level of security is to be ensured than in normal operation, the sensitivity in the area of the squeezing and shearing points, for example of the vertical sensor, can be switched to a higher sensitivity shortly before the rotating wing arrives on the drum wall. This dynamic operation would result in an even greater degree of safety for the user, particularly in the area of the large danger points. After this Passing the front edge of the drum wall would then reduce the sensitivity back to the normal level. If a person or an object is now detected by the vertical or the horizontal sensor bar located on the floor, which is otherwise located on each rotating wing, the rotating door is brought to a standstill. This ensures that there is no danger to the user from the revolving door.
  • the wing arrangement of the revolving door (1) is located between the floor support (3) and the ceiling support (2).
  • the number of rotary blades is arbitrary. There can be two, three or four-leaf revolving doors.
  • the rotary blades (4), (5), (14) and (15) are located on the central axis (16).
  • the rotary blades are framed by two curved drum walls (6) and (7).
  • a sensor (12) is located on each of the wings (4), (5), (14) and (15) on the lower transverse spar (10). This sensor (12) is preferably designed as an elongated sensor strip.
  • the sensor strips (12) located on the floor secure the floor area and thus the air gap between the cross member (10) and the floor (17).
  • This sensor (11) also radiates a field in the form of a lobe, and thus detects people and objects that cause a field disturbance. This is particularly the case when the rotary leaf (4), (5), (14) or (15) approaches the area of the main closing edges (8) and (20). These main closing edges (8) and (20) in connection with the tapering edges of the rotary leaves (4), (5), (14) and (15) represent crushing and shearing points. For this reason, they must be specially secured in order to to avoid crushing people or objects.
  • the proximity sensors which are preferably designed as capacitive sensors, are switched on and can thus detect any dangerous disturbance in the sequence of the revolving door and bring it to a standstill.
  • This operation can be referred to as static operation since the sensitivity of the sensors (11) and (12) is not changed.
  • a switch can be made to dynamic operation. This can preferably be triggered by a corresponding sensor which is located on the axis (16) in the door. Due to the dynamic operation, a person or an object is detected even faster due to the higher sensitivity of the sensor bar (11) in the area (13).
  • circuitry it can also be implemented in such a way that the vertical sensor strip (11) moves in dynamic operation and the horizontal sensor strip (12) in static operation.
  • the signals supplied by the amplifiers of the capacitive proximity sensors can be fed to separate evaluation circuits which are still assigned to certain functions. However, it is also possible to supply these signals to an amplifier with a corresponding comparator stage, which shuts down the entire drive when a threshold value is exceeded.
