Definitions

  • the invention relates to a turnstile with a housing, a drive shaft, and locking arms projecting at an angle therefrom, each of which extends in the locking position approximately at right angles to the passage direction, with a drive motor which can be set in motion without contact, in particular after checking the access authorization of a passing user, to turn the next turnstile locking arm into the locked position.
  • Such a turnstile can be found, for example, in AT-B 389 736.
  • Proximity sensors with a switching distance of approx. 5 cm, which are arranged in the locking arms and are not explained in more detail, recognize the presence and speed of the passing person and set the drive motor in motion, so that the turnstile is driven at a speed adapted to the passage speed.
  • a second sensor on each subsequent locking arm detects when the person touches that the person has stopped and the turnstile stops. This means that the direction of passage can be changed easily. Since each locking arm is equipped with a proximity sensor and a touch sensor, and the signals emitted by the respective sensor have to be transmitted into the housing via the rotating shaft, the structure is relatively complicated and also prone to failure.
  • a turnstile is known from SU-A 1 476 507, in which a light beam network is formed below the cone described by the blocking arms, which network complements the turnstile.
  • the turnstile has a brake, through which the turnstile is in any position can be blocked, with no specific blocking position having to be determined, since the light beam network recognizes an unauthorized passage in any case.
  • a revolving door is known from CH-A 623 112, which can be activated by means of a coin or a data carrier.
  • a light barrier that runs diagonally through the access in front of the turnstile is connected in series with the release device of the turnstile. Since the light barrier is arranged in front of the blocking position, passage can only be made possible in this direction.
  • the invention has now set itself the task of developing a turnstile that switches on without being touched by an authorized passer-by, in such a way that the control device detects a passage attempt from the wrong side, and that the direction of passage can be reversed in a simple manner.
  • this is achieved in a first embodiment in a turnstile of the type mentioned at the outset in that the blocking position of the blocking arm lies centrally in the detection area of an optoelectronic sensor.
  • the drive of the turnstile is switched on.
  • the sensor is installed below or above the drive shaft in the housing so that the signal can be transmitted to the motor control in the usual way via fixed lines.
  • the direction of passage is particularly easily reversible and that The turnstile can be used for both inputs and outputs by simply changing the control system.
  • a turnstile released due to a positive control should be rotated by the user as soon as it is ready for passage, so that the subsequent motor drive takes place at the expected moment.
  • the turnstile according to WO-A 93/03251 therefore, after pressure on the locking arm of the released turnstile, there is first only a rotation by a small angle into a subsequent stopping position, a latching resistance having to be overcome. The user then advances, and a further external action on the locking arm then allows the drive motor to turn the turnstile until the next locking arm is in the locked position.
  • Such a release procedure can also be achieved in a second embodiment with the turnstile according to the invention if the turnstile has a stopping position at an angle after the locking position and if the optoelectronic sensor in the passage direction behind the locking arm standing in the locking position at an angle between the locking position and the stopping position is arranged.
  • the turnstile can also be passed on skis and on slightly rising floors by smaller children as well as adults, without causing difficulties.
  • the optoelectronic sensor has at least one Changes in reflection of an emitted light beam appealing light scanner, which is equipped with an external light and background suppression.
  • the transmitted detection beam is reflected by the passing user.
  • the reflected light strikes a first light receiver which compares the received light component with that light component which is reflected on a second light receiver from the background which is at a greater distance. Since the positions of both light receivers can be adjusted, this enables the range of the detection beam to be limited by determining the distance of its intersection with the reflection beam of the second light receiver. This difference method is largely independent of the reflection properties.
  • the light scanner emits infrared light.
  • the optoelectronic sensor comprises two light sensors, the detection beams of which lie at a small angle on both sides of the blocking arm. Regardless of the direction of passage, the turnstile drive is only put into operation when the first light switch in the direction of passage responds; however, if the second light button responds first, a brake can be activated.
  • a DC motor which can be short-circuited in the stopping position, is used in particular to drive the turnstile. Furthermore, it is preferably provided that a worm wheel is arranged on the drive shaft, in which a non-locking worm engages, on the shaft of which a magnetic brake and a direction of rotation detection device are provided, and which is driven by the motor via a traction means.
  • the magnetic brake can be activated in particular in the locked position.
  • FIG. 1 shows an oblique view of a first exemplary embodiment of the turnstile
  • FIG. 2 shows a schematic top view of a blocking position
  • FIG. 3 shows a schematic top view of a stopping position
  • FIG. 4 shows a schematic top view of a release position of the user
  • FIG. 5 shows an oblique view of a second embodiment of the turnstile
  • Fig. 6 is a schematic plan view of the blocking position
  • Fig. 7 is a schematic representation of the transmission area.
  • the housing 2 of a turnstile 3 is arranged on a frame 1 so that it can be adjusted in height.
  • the turnstile is assigned to a through lane and has three locking arms, of which the upward locking arm 4 is in a locking position which lies at an angle of approximately 10 ° in front of a center line drawn in broken lines.
  • a worm wheel 11 is fastened on the shaft of the turnstile 3, into which a non-inhibiting worm 12 engages, which is driven by an electric drive motor 16 via a traction means 13.
  • the turnstile 3 is held in the locked position of each locking arm 4 by an electromagnetic brake 8 which engages the shaft of the worm 12.
  • a direction of rotation and angle of rotation detection disk 14, to which a detector 15 is assigned, is also arranged on this shaft.
  • the turnstile is also equipped with an optoelectronic sensor 5 the drive motor 16 is switched, and in the embodiment according to FIGS. 1 to 4 provided with a control device 7, to which a transceiver unit 8 shielded from the surroundings, a magnetic card reader 9 with a display 10 and a corresponding control circuit are assigned.
  • FIG. 2 shows the locked position of the turnstile. A user 18 standing in front of the locking arm 4 cannot be detected by the detection beam, since this is behind the locking arm. If the control device 7 assigned to the turnstile 3 grants permission for the passage of the through lane, the brake 17 is released and the drive motor 16 rotates the respective blocking arm 4 from the blocking position into a stopping position in which the motor 16 is stopped again.
  • the turnstile only rotates a few degrees to release the detection beam (Fig. 3).
  • the brake 17 remains released in the stopping position. If the user 18 moves this short way forward, he is, as can be seen from FIG. 4, detected by the detection beam 6, which in turn switches on the motor 16 of the turnstile. The latter rotates the turnstile 3, releasing the passage, until its next locking arm 4 reaches the locking position in which the brake 17 is activated again.
  • An exact position of the locking arms 4 in the locking position and in the stopping position is of secondary importance.
  • the blocking position or the stopping position could also be perpendicular to the direction of passage. Of course, intermediate positions are also conceivable.
  • turnstile 3 is shown without control device 7.
  • Such a turnstile 3 which only knows a locked position, but no stop position, is often used at the exits of sports facilities to prevent unauthorized access refuse.
  • the turnstile 3 is provided with two optoelectronic sensors 5 in the form of light sensors. Their detection beams 6 extend on both sides of the locking arm 4 located in between. When the user approaches the turnstile from the correct side, the first detection beam 6 first responds to the user, and the turnstile 3 is set in rotation.
  • the motor stops if the second light switch 5 does not respond to the passage of the user in an adjustable time. If, in the given direction of passage, the visitor approaches from the second, ie wrong, side, the second light switch 5 reacts first. Since this is wrong, the motor remains interrupted and the turnstile 3 is locked.
  • the direction of passage can be exchanged in a simple manner, so that the turnstile can be used alternately in both directions.
