Definitions

  • the present invention relates to an emergency release device for a door actuation system with two decouplers, for a double-leaf door, for example, which is orientable or roto-translatable, in particular for means of public transport, such as buses or trains.
  • the single orientable or roto-translatable leaf of the double-leaf door of a vehicle is connected by means of interposing arms, which are orientable, or directly to a rotating column and it is movable, by means of a rotary movement of the rotating column, from an open position to a closed position and vice versa.
  • the movement of the rotating column occurs by means of a rotary drive having an external housing constrained to the structure of the vehicle and an outlet shaft supported in the external housing and connected integrally to the rotating column on rotation.
  • a rotary drive having an external housing constrained to the structure of the vehicle and an outlet shaft supported in the external housing and connected integrally to the rotating column on rotation.
  • the movement of the leaf occurs in response to a rotation of the outlet shaft, while the external housing of the drive is stationary.
  • the movement of the rotating column occurs by means of a rotary drive having an external housing, which forms the rotating column, or which is integrally constrained on rotation to the rotating column, as well as a stationary shaft supported in the external housing and stationarily constrained to the structure of the vehicle.
  • a rotary drive having an external housing, which forms the rotating column, or which is integrally constrained on rotation to the rotating column, as well as a stationary shaft supported in the external housing and stationarily constrained to the structure of the vehicle.
  • the movement of the leaf occurs in response to a rotation of the external housing, while the shaft is stationary.
  • Known electric rotary drives are usually provided with an automatic locking brake, which is permanently elastically pushed into a locking position to keep the door closed with electric drive off, and electrically releasable during operation of the rotary drive.
  • the rotary electric drives In addition to the automatic locking brake, the rotary electric drives must also be provided with a mechanical emergency opening (or release) device, allowing the opening of the door despite being unable to release the locking brake in the event of an electricity failure.
  • a manually operable mechanical decoupler between two reduction stages of the rotary drive, for example, by means of a Bowden cable.
  • the decoupler detaches the two reduction stages of the rotary drive from each other and consequently decouples the rotating column (and thus the leaf of the door) from the side of the rotary drive, which is engaged/engageable by the automatic locking brake. In this way, the leaf of the door can be pushed manually into an open position despite being unable to release the locking brake.
  • Publication EP2803801 A1 by the applicant describes a rotary drive for a door or a ramp, which is orientable and/or translatable on public transport vehicles, comprising an electric motor, a reduction gear arranged on a front side of the motor and connected to a front portion of a motor shaft, an outlet shaft connected to the reduction gear, an automatic locking brake arranged on a rear side of the motor opposed to the front side, which acts on a rear portion of the motor shaft, as well as a decoupler additionally comprised with the automatic locking brake and operable to decouple the rear portion of the motor shaft (preferably on the rear side of the motor) from the automatic locking brake, also in the event of being unable to release the locking brake.
  • each leaf is operated by means of a rotary drive thereof, comprising an automatic locking brake thereof.

  • an emergency release device for a door actuation system with two decouplers described in the introduction, having such features as to ensure a reliable and repeatable operation thereof, with a rapid release effect on both leaves, which is easily operable, without excessive effort by the user.
  • an emergency release device for a door actuation system with two decouplers comprises:
  • the door Due to the displacement of the sliding block by means of a preloaded spring device, and not (or not only) by means of the force exerted by the user by the third Bowden cable, the door can easily be released in an emergency without excessive effort.
  • the locking force, the release force and the locking and release positions of the sliding body, as well as the thrust force needed to push the sliding block into the release position can be selected and set according to design parameters of the door with a double decoupler, independently of parameters of force and geometry of the emergency handle or lever by means of which the third Bowden cable will be operated.
  • the release detector allows the recognition and signaling of a door release state by means of an electric control system of the emergency release device, or of the door, or of the whole vehicle and the electric restore operation allows a restore, for example, automatic, of the emergency release device by means of the electric control system, without the need for further manual intervention.
  • the door actuation system with two decouplers can be associated, for example, with a double-leaf door of the type comprising:
  • Figures from 4 to 7 illustrate an emergency release device 1 for a door actuation system 2 with two decouplers 3, 3', for example, for a double-leaf door 4, 4' or with a single leaf 4, in particular, for a vehicle for transporting people, for example, a bus or a railway carriage.

  • the double- 4, 4' or single-leaf door 4 can be of the type comprising at least one leaf 4, movable between an open position and a closed position by means of a rotary drive 5 thereof, wherein the rotary drive 5 comprises an outlet portion 6 for transmitting the movement of the rotary drive 5 to the leaf 4, and a brakeable portion 7 coupled to the outlet portion 6, an automatic locking brake 8, which acts on the brakeable portion 7 to lock the leaf 4 in the closed position, as well as a first and a second decoupler 3, 3', operable (for example, in sequence) to decouple the brakeable portion 7 from the outlet portion 6 to allow a manual displacement of the leaf 4 towards the open position, also in the event of being unable to release the automatic locking brake 8 ( figures 2 , 8, 9 ).
  • the emergency release device 1 comprises:
  • the guide device 11 comprises two parallel guide bars 21 extending through two guide holes 23 of the sliding block 10, whose opposite ends can be connected to two opposite support walls 22, which can be screwed, in turn, to the metal plate of the support structure 9. In this way, the guide device 11 determines a translation travel direction of the sliding body 10, which corresponds to an actuation (traction) and return translational travel direction of the first Bowden cable 13 and the second Bowden cable 13'.
  • the Bowden coupling interfaces 12, 12' are formed by a rocker arm 26 oscillatingly connected to the sliding body 10 about a rocker arm axis 27 transverse (preferably orthogonal) to the translational travel direction of the sliding body 10, and positioned on two opposite sides with respect to the rocker arm axis 27.
  • a difference in resistance between the first 13 and the second Bowden cable 13' increases the actuation travel of the Bowden cable, offering less resistance to the Bowden cable, which offers more resistance and/or allows an actuation of the two decouplers 3, 3' in a predetermined sequence by means of the difference in the mechanical actuation resistance of the two decouplers 3, 3'.
  • a first Bowden abutment seat 24 and a second Bowden abutment seat 24' are comprised for positioning and stopping external casings 25, 25' of the first Bowden cable 13 and the second Bowden cable 13'.
  • the first 24 and the second 24' Bowden abutment seats can be formed in one same wall, for example, a metal angular profile, formed or screwed to a first wall 22 of the opposite walls 22, 22'.
  • the spring device 14 can comprise a gas spring or a helical spring preferably arranged in an intermediate region between the two guide bars 21, and possibly with an orientation and thrust effect parallel to the direction of extension of the guide bars 21.
  • the spring device can be connected or positioned between the aforesaid first wall 22' of the opposite walls 22 and the sliding body 19.
  • the spring device 14 comprises two springs (e.g. gas or helical) placed parallel ( figure 4 ) to ensure a thrust operation of the sliding body 10 with safety redundancy.
  • two springs e.g. gas or helical
  • the elastic force of the gas or helical spring is adjustable, for example, by means of selecting the preloaded compression length, or by means of adjusting the pressure of the gas in the gas spring, and it is consequently adaptable to the decoupling resistance of the decouplers 3, 3'.
  • the locking mechanism 15 comprises:
  • the hooking lever 28, the projection 33 and the trigger 37 are configured and shaped so that:
  • the hooking seat 34 of the hooking lever 28 comprises a first projection (or surface) 30 and an opposite, second projection (or surface) 31, longer than the first projection (or surface) 30, which mutually delimit a groove 32 so that the first projection (or surface) 30 locks and releases the projection 33 of the sliding body 10, while the second projection (or surface) 31, of a greater length, intercepts the projection 33 when the sliding body 10 returns from the release position to the locking position.
  • the hooking lever 28 is permanently elastically (spring 29) strained towards the release position, in order to ensure the necessary position synchrony for the restore.
  • spring 29 permanently elastically
  • the device comprises a further stop spring 41, which strains the trigger 37 permanently towards the stop position ( figure 7 ), ensuring an operation redundancy of the device 1 restore.
  • the trigger 37 forms a sensing projection or portion 42, which interacts with the release detector 18, for example, switching an electric microswitch between two different switching states, to detect a device state 1 set and not actuated ( figure 5 ) and a device state 1 actuated and not yet restore ( figure 6 ).
  • the stop seat 35 of the hooking lever 28 and the stop portion 40 of the trigger 37 are positioned and shaped so that, when the trigger 37 stops in the stop position and the hooking lever 28 stops in the hooking position ( figure 5 ), a resulting support force 46 between the stop seat 35 and the stop portion 40 (generated by the spring device 14) intersects the trigger axis 38 of the trigger 37.
