Definitions

  • the present invention refers to a safety system for automatic gates.
  • the gate to which the system of the present invention can be applied can be a sliding gate, a swing gate and, more generally the system of the present invention can be applied to barriers in which the access point is opened and closed by at least one door moved automatically.
  • Automatic gates for gaining access to private areas are usually actuated by the users, at fixed control points, through buttons or keys for opening and closing or by means of remote controls, which send a radio impulse to an electronic control station, which takes care of actuating the gate in the desired direction.
  • Such ribs are positioned at the most dangerous edges, they are made from soft material and transmit, for example by means of manostats, an electric signal to a contact of an electronic transmitter whenever the pressure inside them varies, for example in the case of contact and accidental collisions caused by vehicles as they pass.
  • the electronic transmitter immediately sends an impulse to a receiver, which can be activated through radio contact, which is located separately around a fixed point and that immediately takes care of interrupting the power supply to the system; consequently, if the gate is moving, it instantly locks in the position reached.
  • ribs again made from soft material, which contain a taut steel cable inside them, which connects a contact of an electronic transmitter by means of leverisms, whenever the tension of the cable increases by a predetermined value, for example through a microswitch.
  • the microswitch takes care of interrupting the power supply to the system.
  • the protective rib is mounted, through the application of an aluminium shaped profile, on the front surface in the direction of movement of the sliding door of the gate itself.
  • the transmission of the signal generated by the protective rib to a control station of the gate is a transmission that takes place via radio, or else it is a transmission that takes place via cable from the sliding door to the fixed part of the gate, through flexible electric cables or through sliding trolleys on the gate.
  • each of the known methods for the transmission of a signal to the rib has reliability problems.
  • the interruption signal transmitted via radio from the ribs to the control station of the gate can suffer from disturbances such that it may not be perceived and therefore recognised by the control station.
  • An interruption signal transmitted via cable determines the need to lay cables between a fixed part and a mobile part of the gate with a consequent possibility of breaking and/or damage in time.
  • the Applicant has found a simple and reliable way to carry out such a transmission of the signal of the rib, which uses a connection, determined by an infrared signal, between the fixed part and the moveable part of the gate.
  • a connection is always kept active between the fixed part and the mobile door of the gate, generated by an infrared transmitter and received by a corresponding receiver; an intervention signal of the rib, due for example to a collision against an obstacle of the rib itself, deactivates the infrared transmitter and generates an interruption of the connection between the mobile part and the fixed part of the gate.
  • Such an interruption is received by the control station of the gate that interrupts the moving gate itself.
  • An aspect of the present invention concerns a safety system for an automatic gate, said gate comprising a mobile door, suitable for covering an access space defined at the ends on fixed sides of said gate, which has a protective rib suitable for generating a detection signal of the contact of the mobile door with an obstacle, characterised in that it comprises a device for generating an infrared signal describing a state of correct operation of the gate and the lack of reception of said signal resulting in the stopping of the movement of said door.
  • the automatic gate comprises a sliding door 10, illustrated as an example in the figures as being rectangular in shape, which slides inside a guide 11 fixed on the ground and covers and access space.
  • a guide 11 fixed on the ground and covers and access space.
  • Such an access space is defined at its ends by fixed parts of said gate that comprise a post 12, annexed for example to a wall 13, and an upright 14.
  • the sliding door is moved inside said guides by a motor, for example an electric motor.
  • the sliding door 11 is provided with a protective rib 15, made from rubber or in any case from a soft material, being substantially in the shape of a triangular prism and associated with a front wall of said door.
  • the protective rib can be made according to different technologies that are equivalent to each other, which, at a pressure applied on the soft material of said rib, generate a signal or interrupt an electric signal, so as to indicate that a collision of the rib against an obstacle has occurred and that the movement of the sliding door should be stopped.
  • the gate is moved by said motor, which is controlled by an electronic control unit situated close to the fixed parts of the gate.
  • the rib 15 illustrated in figures 1 and 2 is of the cable type; in particular, inside the rib 15 runs a cable, for example made from steel, arranged vertically, immediately below the rubber surface of the rib.
  • Said rib is also provided with a microswitch system, preferably arranged on the top of the rib itself, mechanically connected to said cable and able to be activated by it in response to a traction of the cable, for example caused when pressure is exerted on the soft material of said rib.
  • a microswitch system preferably arranged on the top of the rib itself, mechanically connected to said cable and able to be activated by it in response to a traction of the cable, for example caused when pressure is exerted on the soft material of said rib.
  • the safety system uses the alarm signal generated by the microswitch inside the rib to communicate a state of alarm or a state of correct operation of the rib itself.
  • the state of alarm identifies a condition in which there has been a collision of the sliding door against an obstacle during its movement, or else it can identify an operating anomaly of the rib such as to require the interruption of the operation of the gate as a whole.
  • the safety system comprises a transmitter 16, situated on the top of said sliding door 10, preferably associated with the head of the protective rib 15, and a receiver 17 situated on the fixed parts of the gate, for example close to said post.
  • a transmitter and such a receiver are arranged with respect to each other so that an infrared signal transmitted by said transmitter can be received by said receiver.
  • the transmitter is an infrared receiver and the receiver is an infrared receiver.
  • the transmitter and the receiver are preferably aligned with each other on the top of said gate.
  • the infrared transmitter 16 is actuated by a pilot circuit (not shown in the figures) comprising a microprocessor, which activates or deactivates the transmitter itself based upon the electric signal received by said protective rib. Moreover, such a transmitter and the pilot circuit are supplied with power by a long-life battery.
  • the microswitch actuated by the cable of said rib is connected with said pilot circuit.
  • said receiver 17 is connected to a decoding circuit connected to the electronic control unit of the gate.
  • Said pilot circuit is suitable for keeping the transmitter active during the normal operation of the gate, through the sending of a predetermined infrared signal, whereas, following a change in the signal of the rib it deactivates the infrared transmitter, identifying a state of alarm.
  • the decoding circuit receives the state of alarm following the lack of reception of the infrared signal and sends a locking signal to the control unit of the gate that stops the motor and the movement of the gate itself.
  • the transmitter is preferably supplied with power by a battery, which needs to be replaced regularly; for such a purpose, the system of the present invention comprises a circuit for indicating the charge of the battery, which foresees the presence of an indicator light of the charge of the battery situated close to said receiver.
  • the pilot circuit of the transmitter encodes the infrared signal inserting inside it the information on the state of the battery.
  • the decoding circuit can decode such information contained in the infrared signal and activate said light for indicating the state of the battery.
  • the pilot circuit can encode the infrared signal by inserting regular impulses a predetermined distance apart from each other.
  • the pilot circuit can intensify or reduce the frequency of said impulses.
  • the decoding circuit on the receiver can activate the indicator light at such a variation in frequency of the impulses.
  • a suitable adjustment of the system can adjust the switching on of the empty battery light sufficiently in advance of the actual empty battery condition (for example two or three months before).
  • such an indicator light is on the receiver, since it can easily be supplied with power by the electronic control unit of the gate, ensuring that the electronic circuits contained in the pilot circuit that commands the transmitter is reduced to the minimum.
  • such a light can be placed directly on the transmitter.
  • the system of the present invention can equally be applied to gates or front doors in which the door moves in a different way, provided that the infrared transmitter and receiver are always aligned with each other, so as to allow the correct communication between them.
  • the transmitter is associated with the mobile door of the gate and the receiver is associated with the fixed part of the gate.
  • the present invention could arrange both the transmitter and the receiver on the fixed part of the gate and associate a reflector with said protective rib positioned so that the infrared signal transmitted by the transmitter is reflected by the reflector in the direction of the receiver.
  • the present invention refers to the generation of an infrared signal, which places the mobile door, and therefore the protective rib, in communication with the control station and therefore the fixed part of the gate.
  • the present invention comprises a device for generating an infrared signal that comprises an infrared transmitter, receiver and reflector.
  • the generation device of the present invention comprises just one infrared transmitter and receiver.
  • the infrared signal describes a state of correct operation of the gate and the lack of reception of said signal results in the stopping of the movement of the mobile door of the gate.
