Definitions

  • the present invention refers to a motorized bar barrier device which permits fitting the bar for right or left opening without having to adjust the balancing system.
  • the second solution causes a dissymmetry in the appearance of the right barrier with respect to the left barrier (turned in the opposite direction), visible above all when two contrasting coupled barriers are used at the sides of a same passageway. Furthermore, the manual release mechanism of the bar could find itself turned towards the wall that delimits access, with the consequent difficulty or impossibility of operation in case of a fault in the power drive or of a power outage.
  • the general object of the present invention is to overcome the drawbacks mentioned above, providing a barrier device with balancing system that can offset right or left opening bars indifferently.
  • a motorized bar barrier device comprising a shaft supporting the bar, a motor unit for the rotation of the shaft and a unit for offsetting the moment produced on the shaft by the weight of the bar, wherein the offsetting unit comprises a torsion spring wrapped coaxially at the shaft and having a first end that is pushed by the rotation of the shaft to wind the spring when the shaft is turned in a first direction starting from a neutral position and a second end that is pushed by the rotation of the shaft to wind the spring when the shaft is turned in a second opposite direction starting from the neutral position, so as to provide at least partial offsetting of the moment produced by the weight of the bar in both the directions of rotation starting from the neutral position.
  • the offsetting unit comprises a torsion spring wrapped coaxially at the shaft and having a first end that is pushed by the rotation of the shaft to wind the spring when the shaft is turned in a first direction starting from a neutral position and a second end that is pushed by the rotation of the shaft to wind the spring when the shaft is turned in a second opposite
  • FIG. 1 represents a partial schematic and perspective view of a barrier device according to the invention
  • FIG. 2 represents a schematic plan view of the device of FIG. 1 ;
  • FIG. 3 represents a partial schematic and perspective view of a rear part of the device of FIG. 1 ;
  • FIG. 4 represents a partial schematic and perspective view of a release element of the device of FIG. 1 ;
  • FIG. 5 represents a rear perspective view of the barrier device of FIG. 1 equipped with wall fastening.
  • FIG. 1 shows (with broken line and removed closing cover) a bar barrier device, indicated generically by 10 .
  • the device 10 comprises a body 11 containing a motor unit 12 and a balancing unit 13 , connected to a rotation shaft 14 onto which is fastened a plate 15 for fitting a bar 16 .
  • the rotation shaft 14 (supported by a pair of bearings 17 and 18 ) supports a gear 19 on which is engaged a pinion 20 of a gearmotor 21 .
  • the gear 19 is engaged on the shaft in a releasable way by means of a release system 22 driven by an operating lever 23 (if necessary protected by a key cover, not shown).
  • the shaft 14 crosses a torsion spring 24 of the balancing unit 13 and protrudes at the rear to integrally support an arm 25 which in turn supports a thrust pin 26 positioned parallel and radial at a distance from the shaft 14 .
  • the spring has a first end 27 that is pushed to wind the spring when the shaft is turned in a first direction starting from a neutral position (corresponding to the bar in vertical position) and a second end 28 that is pushed to wind the spring when the shaft is turned in a second opposite direction starting from the neutral position.
  • the torsion spring 24 in the vertical bar position, has the two ends 27 and 28 that extend in a radial direction to rest symmetrically on the two sides of the pin 26 in the direction of traction of the spring.
  • the torsion spring will be advantageously pre-loaded to favor the stable maintaining of the vertical position of the bar with a desired force.
  • Single-directional stop means of the ends of the spring are also present to stop the movement of each end of the spring in the direction opposite to the thrust direction of the pin to wind the spring starting from the neutral position. These means are advantageously made with the bottom or end part of the cracks 29 , 30 , made in a covering shell of the spring, through which pass the ends of the spring.
  • the bar to complete its closing movement, must turn by 90° (in an anticlockwise direction in the case shown in the illustrations), advantageously between two mechanical stops.
  • One of the two mechanical stops is mobile because when a contrary rotation of the rod is to be made the lever must start from the same vertical position but turn in the opposite direction, where it will find another fixed stop.
  • the rear lever 25 turns by 90° from the vertical position (shown by the unbroken line) to horizontal position (shown by the broken line).
  • Mechanical stop means are envisaged to restrict the shaft rotation movement between the vertical position and the horizontal position of the bar.
  • Such means are also adjustable to selectively have the horizontal position either in a clockwise direction or an anticlockwise direction with respect to the vertical position of the bar.
  • the movement between the two positions is advantageously delimited by a vertical position stop 31 and a horizontal position stop 32 respectively.
  • the vertical stop is made in the shape of an invertible plate 31 so it can be mounted to prevent a further anticlockwise movement (as shown in the FIG. 2 ) or clockwise movement (by upturning the plate to the right of the lever, as shown by the broken line in FIG. 2 ) and thereby realize the above-mentioned mobile stop.
  • the horizontal position of the lever will be overturned to the left and the horizontal stop will be stop 33 (mirrored with respect to stop 32 ).
  • FIG. 4 shows in greater detail the bar release system, to be operated when the bar has to be operated manually while always maintaining the spring balancing effect.
  • the purpose of the release is to free the bar from the irreversible gearmotor.
  • the release system comprises releasable means of engagement between gear 19 and shaft 14 .
  • the engagement means comprise an elongated element 35 that crosses the shaft 14 transversally at a slot or milling 36 on the shaft to be able to slide axially to the shaft against the action of a thrust spring 37 .
  • the spring 37 pushes the element 35 inside a radial seat 38 of a bush 39 integral with the gear 19 , and which is freely turning on the shaft 14 .
  • An operating pin 40 (shown by a broken line in FIG. 2 ) can slide axially in the shaft 14 to push on the element 35 by operating the lever 23 and to disengage it from the bush 39 .
  • the bush 39 has several radial seats distanced at angles (e.g., every 30°), so the rod can be re-blocked in intermediate positions.
  • the balancing of the rod is done by rotating an appendix of the torsion spring which winds up during bar movement: to balance the rod in the contrary application, simply rotate the rod by 180 ° (if required by the support), turn the mobile stop and in this way the exit shaft, by turning in the opposite direction, will move the other appendix (while the first will remain still) permitting the balancing of the bar.
  • a further advantage of the described device is to have the release on the same side when, at an entrance, there are two contrasting barriers.
  • rod balancing is done advantageously with a moment that is directly proportionate to the torsion of the spring.
  • the spring can be suitably selected according to the weight of the bar, so that the moment generated by the spring is very similar to the opposite moment generated by the weight of the bar and during the entire bar movement the motor can operate at minimum load and therefore runs almost at top idling speed.
  • the rods can be advantageously sized to have the same static moment with respect to the centre of rotation in their maximum length and when the rods are to be shortened (within certain limits), to ensure best barrier operation, simply add a suitable weight to offset the lost static moment. This way, it will not be necessary to have several springs for different rod lengths.
  • the device according to the invention also has the novel characteristic of being able to be fixed directly to the wall, without the traditional pedestals of prior art, thanks to the innovative structure of the offsetting system which allows the device to have a compact shape in a vertical direction and limited depth, release on front and reversibility of the direction of bar opening/closing without having to turn the actuator body.
  • FIG. 5 shows the device of FIG. 1 complete with a support 41 , advantageously fixable to the base of the body 11 , and having at the rear fixing means 42 (e.g., holes with screw anchors) for wall mounting.
  • the position of the bar with respect to the rotation axis and its mounting system can vary according to specific requirements, including of an aesthetic nature.
  • the arm that interferes with the mechanical stops of the two extreme bar rotation positions can if necessary be separated from the supporting arm of the thrust pin 26 .
  • the bar release means can also be missing or be different from those advantageously described.
