Definitions

  • the present invention relates to a folding or rotating gate with two or more gate wings comprising: a post, a first gate wing which is hingeably connected to the post, a second gate wing which is hingeably connected to the first gate wing and drive means configured to fold the first and second gates wing open or shut, wherein the drive means comprise a first drivable hinge configured to drive the first gate wing and a second drivable hinge configured to drive the second gate wing.
  • the present invention relates in particular to an automated rotating or folding gate which opens and closes quickly.
  • rotating or folding gate which opens or closes in a few seconds is often opted for, thus offering a considerably higher level of protection compared to standard automatic gates or doors.
  • Such rotating or folding gates are also seen as a high-quality alternative for barriers and have the additional advantage that they also impede the free passage of pedestrians and two-wheelers.
  • rotating or folding gates are opened and closed by installing an electrical, pneumatic or hydraulic drive means on the post for driving the first gate wing.
  • the second gate wing is driven mechanically by means of rods, gear racks or drive belts which are attached to the first gate wing.
  • the transmission mechanism requires considerable maintenance, due to the large number of mechanical components.
  • the mechanical drive is fitted in either the upper or lower housing of the rotating or folding gate, in practice often also referred to as speed gate or bi-folding gate.
  • European patent EP 1 595 050 B1 describes a number of embodiments of folding gates.
  • the folding gates described comprise: a post, a first gate wing which is hingeably connected to the post, a second gate wing which is hingeably connected (mechanically coupled) to the first gate wing, drive means configured to drive the first gate wing and a transmission mechanism configured to transfer the movement of the first gate wing onto the second wing, so that the first and second gate wing simultaneously are folded open or shut. Since, with these kinds of folding gates, the second gate wing is actuated by the first gate wing, at most two successive gate wings may be automated.
  • Netherlands patent NL 1032983 describes a folding gate comprising a first gate segment which is hingeably connected to a post, a second gate segment which is hingeably connected to the first gate segment.
  • the folding gate comprises first and second drive means, respectively, in the form of a first and second drum motor.
  • the folding gate is furthermore provided with safety means, such as photosensors and/or contact sensors.
  • the object of the present invention now is to provide an alternative automated rotating or folding gate which is opened in a different way to the prior-art gates.
  • a rotating or folding gate comprising:
  • the driven hinges cause the first and the subsequent gate wings to fold open or shut and, in a preferred embodiment, each have a motor driver and positioning sensors, preferably encoders, which offer the possibility of driving the gate wings independently from each other, irrespective of torque, speed and rotation angle.
  • a motor driver and positioning sensors preferably encoders
  • the gate wings may be fully synchronized with one another.
  • Such a rotating or folding gate may, in addition, be opened and closed in one smooth movement.
  • the first and second hinges each comprise a motor and a reduction gearbox, a socalled motor/reductor assembly.
  • the reduction gearbox or gearbox reduces the rotation speed of the motor to the desired number of revolutions per minute and will consequently increase the torque.
  • the reduction gearbox has a torque of at least 800 Nm. More particularly, the torque is 800 Nm.
  • a special reduction gearbox was developed, namely a derivative of a cycloid transmission.
  • the high torque is required to move the weight of the gate wing, taking into account the wind load, and also to protect against the manual application of a load on the rotating or folding gate in the open or closed position (vandalism-proof).
  • the first and second positioning sensor in a more advantageous embodiment of the rotating or folding gate according to the invention, are provided in a separate housing, each of which is attached to the gate in such a way that the first and second positioning sensor are situated axially with respect to the motor and reduction gearbox (motor/reductor) of respectively the first and second hinge.
  • each housing is preferably fitted to a hinge plate on the bottom side of the gate.
  • each housing comprises a damper and stabilizer body. The damper and stabilizer body will prevent the gate wings from wobbling and help to detect the exact position of the gate wings.
  • the gate comprises a driven hinge which may be synchronized with the other gate wings (see robot arm) for each gate wing.
  • said hinges are electrically, pneumatically or hydraulically drivable.
  • the rotating or folding gate comprises a third gate wing which is connected to the second gate wing
  • the drive means obviously comprise a third positioning sensor which is configured to determine the position of the third gate wing with respect to the second gate wing.

  • the processing unit is preferably provided in the post.
  • the positioning sensors used are preferably Hall sensors. Such Hall sensors are able to measure the position of the gate wing to an accuracy of 0.05° at any moment. Using the measured position, the motor may be adjusted by means of software in order to allow the gate to open safely and quickly.
  • said driven hinges comprise a slip ring for transmitting the electrical and/or data signals from one hinge to the other.
  • the electrical signals and data signals may be used to drive the hinges or to transmit data to the processing unit, respectively.
  • one of more photocell sensors may be provided.
  • the photocell sensors contribute to the safety of people and vehicles.
  • a signal may be sent to the motor driver which can then decide to close or not to close the gate.
  • the legally required safety strips may also be provided in each gate wing and be incorporated in the safety system.
  • Other detection means such as for example: vehicle loops installed in the ground, photocells, radar systems, etc. may furthermore be added to the rotating or folding gate according to the invention.

  • Each gate wing (3, 4) can pivot about a hinge pin which extends vertically.
  • the entire gate (1) can swing open or shut and can thus be moved from an open position, as illustrated in Fig. 2 , to a closed position, as is illustrated, inter alia, in Figs. 1 and 4 .
  • the first gate wing can swing through 90° and the second gate wing can swing through 180°.

  • the gate (1) is made from metal or aluminium.
  • the rotating or folding gate (1) also comprises drive means which are configured for, preferably simultaneously, folding the first (3) and second (4) gate wing open or shut.
