Definitions

  • This invention refers to an electromechanically actuated mobile protect-ion device for automatic gates.
  • the gates are usually operated by the users from fixed sites, by using opening and closing pushbuttons or keys or remote control devices sending out radio impulses to an electronic panel which takes care of actuating the gate in the desired direction.
  • the re-closing of the gate after its opening occurs after sending out a further user command, or automatically after a certain pre-established period of time.
  • the traditional safety and protection systems generally used on automatic sliding gates are mainly based on the use of a mobile pneumatic rib set on top of the gate, which by a pressure-operated cut-off switch transmits an electric signal to an electronic transmitter contact whenever its internal pressure varies, for instance in case of any accidental contacts or bumps caused by passing vehicles.
  • the electronic transmitter immediately sends out an impulse to a receiver operated by radio contact and installed at a nearby point, which instantly acts to shut-off the electrical power supply to the system.
  • any violent bumping or shaking effects on the gate may cause the air chamber inside the pneumatic rib to crack or fail without being noticed in time by the user, thus causing an undesirable malfunctioning of the system.
  • the electronic transmitter is fed by a local battery, which may be suddenly discharged and impede the operation of the safety device in case of actual need.
  • the purpose of this invention is to produce an electromechanically actuated mobile protection device for automatic gates, capable of overcoming the mentioned drawbacks.
  • the scope of this invention is to indicate an electro-mechanically actuated mobile protection device for automatic sliding gates, capable of acting more quickly than that of the prior art in case of an imminent danger, for instance whenever an object obstructs the access path during the forward motion of the gate, meaning its opening or closing phase.
  • Another scope of this invention is to produce a mobile protection device for automatic gates, less affected by wear or aging in time with respect to any known designs.
  • a further scope of this invention is to indicate a mobile protection and/or safety device for automatic gates, capable of being operated by an electromechanical device and thus more reliably than the traditional designs of an electrical and/or electronic type.
  • An additional scope of this invention is to indicate an electromechanically operated mobile protection device for automatic gates, capable of functioning in a precise and proper manner in every situation.
  • a further scope of this invention is to indicate a mobile protection device for automatic gates, capable of being easily and economically produced, while employing simple manufacturing technologies and relatively inexpensive components.
  • a protection rib is produced from a flexible material and firmly affixed to the top of an automatic gate, so as to also prove mobile, during the motions of the gate, in the direction of the gate's forward motion, both during a gate opening or closing phase.
  • the rib houses in its interior a small tensioned steel cable, placed vertically so as to mechanically transmit any accidental contact or impact against the rib over rollers to a fixed trolley inserted inside a rail-like section bar firmly attached to the structure of the gate and connected by a guide plate to one of the concrete pillars delimiting the access to the private area.
  • the trolley comprises a spring-actuated control slide, which sends an acceptance signal to an electronic triggering and/or safety device (microswitch) which in turn shuts-off the electrical power supply to the gate-driving motor, thereby instantly locking it in the position assumed at the instant of contact with the foreign object.
  • microswitch electronic triggering and/or safety device
  • the mobile protection device object of this invention may also be applied to automatic gates of a different design, for example to those of an oscillating or a double gate type, just as the cable-guiding rail may be installed in a different position, such as for instance in the lower part of the gate.
  • 10 generally indicates a protection rib built of rubber or at any rate of a flexible material and essentially shaped like a triangular prism, 11 indicates an automatic sliding gate, and 12 the advancing front face of the gate 11 holding the attached rib 10, as shown in Figure 1.
  • the automatic gate 11 slides inside a guide 36 attached to the ground and provides access to a private area, delimited at the extremities by a pillar 18 attached to an enclosing wall 19 and by an upright support 20.
  • a steel cable 13 slides inside the rib 10, as represented by a dashed and dotted line in the Figures 1 - 3 and arranged in a vertical manner, immediately below the rubber surface of the rib 10.
  • the cable 13 is therefore inserted inside the section steel indicated by 21, which is horizontally positioned along the upper face of the gate 11.
  • the section bar 21 is profiled in the form of a U-shaped rail, so as to allow inserting a trolley 15, attached opposite the pillar 18 by a fastening arm 22 and a plate 24.
  • the fastening arm 22 can be attached to the trolley 15 and alternatively to the points 25 and 26 by using a spherical joint 23, which constitutes an appendix of the arm 22, and by a screw 27.
  • the arm 22 is moreover connected to the plate 24 fitted at its lower surface with two guide rollers, shown by 31, for the gate 11.
  • the trolley 15 is also equipped with a set of guide rollers 32, which act as a stop against the internal walls of the section bar or rail 21.
  • the steel cable 13 passed over the pulley 14 and horizontally positioned inside the rail 21 therefore rests on the trolley 15 where it follows a winding path while leaning against the three transmission rollers indicated by 29, fastened to the trolley 15 and arranged at the tips of a hypothetical isosceles triangle.
  • the trolley 15 comprises a control slide 16 connected to one of the transmission rollers 29 and to at least one tensioning spring 33 for the slide 16, arranged in a fixed and pre-established position.
  • the slide 16 automatically governs the operation of an electronic triggering device 17, such as for instance a microswitch, by using a transmission element 34.
  • the operation of the electromechanically actuated mobile protect-ion device for automatic gates is as follows.
  • the access of the vehicles to the private area is allowed when the gate 11 is fully or partially opened.
  • the opening of the gate 11 occurs on the other hand in a traditional manner by a remote control actuated by the user or by a signal originated by a wall-type remote control or pushbutton panel.
  • the mobile rib 10 firmly attached to the wall 12 allows taking an instant action in the interest of protection and/or safety, by interrupting the motion of the gate 11.
  • the motion of the slide 16 triggers the electronic device 17 and mechanically actuates the connecting element 34.
  • the device 17 being electrically coupled to an electrical panel which is in turn directly connected to the driving motor of the gate 11, acts by instantly interrupting the electrical power supply to the mentioned motor.
  • the mobile protection device described by this invention allows preventing any dangerous problems inherent in moving an automatic gate 11, by quickly and precisely acting on the electrical system moving the gate 11, even if the rubber or flexible material constituting the rib 10 is damaged.
