  • known actuating devices further comprise a support structure, which is usually shaped as an L-shaped support plate having a horizontal portion suitably drilled in order to allow the stem to slide therein, which is fixed to the cylinder head.
  • the mechanical block usually consists of a roller supported by a lever that is directly hinged in the vertical portion of the L-shaped support plate and held by a spring in such a position that it abuts against a plate formed at the base of the upright.
  • This roller is driven by a pneumatic cylinder, which is also directly fixed to the vertical portion of the L-shaped plate, which pushes it outside the periphery of the plate, when the upright is required to be moved down.
  • a leverage is provided, which is directly hinged to the L-shaped plate, and when manually operated, it acts on said roller for moving the latter outside the periphery of the plate, thereby allowing the upright to move down.

  • the recessing seat 22 is suitable to be engaged with a lock portion 24 formed by the profile of the second cam 19.
  • the first cam 18 When this engagement is removed by rotating the second cam 19 in the counter-clockwise direction in a release position, the first cam 18 is no longer capable of bearing the weight transmitted by the plate 23 and thus rotates in the counter-clockwise direction by being pushed by the plate 23 of the upright 12 against the elastic force of the spring 20 (door opened).
  • the spring 20 causes the first cam 18 to rotate clockwise thus taking back the latter to an angular position suitable to allow the engagement of the recessing seat 22 of the first cam 18 by the lock portion 24 of the second cam 19.
  • the release means 8 are connected to the second cam 19, such as to govern the movements thereof.
  • release means 8 advantageously comprise first release means, preferably pneumatically operable, which ensure the regular downward movement of the upright 12 under regular conditions of use, i.e. in the absence of failures in the pneumatic supply circuit (not shown in the figures).
  • the release means 8 further comprise second release means, preferably mechanically operable, which ensure the downward movement of the upright 12 and consequently the opening of the door 2 also in the presence of failures in the pneumatic supply circuit and pressure loss.
  • the first release means advantageously comprise a pneumatic and a single-acting release cylinder-piston unit 25 that is in fluid communication with the main cylinder-piston unit 10.
  • the release cylinder-piston unit 25 is preferably laterally fixed to the auxiliary support plate 19, e.g. by means of welding.
  • the release cylinder-piston unit 25 is positioned such that an outer end of a stem 26 thereof can be connected to the second cam 19. Thereby, by moving out and in, the stem 26 causes rotations of the second cam 19, clockwise and counter-clockwise, respectively.
  • the single-acting release cylinder-piston unit 25 is positioned and configured such that, in the absence of pneumatic supply, due to the elastic bias of a spring inside the cylinder body (not shown in the drawings), the stem 26 is held in a position suitable for holding the second cam 19 in the blocking position.
  • the stem 26 moves at least partially into the release cylinder-piston unit 25 and causes the second cam 19 to rotate counter-clockwise, such as to take the first and second cams 18 and 19 to the release position (door opened).
  • the stem 26 is externally threaded at the end thereof outside the release cylinder-piston unit 25.
  • stops 42 can be provided on the stem 26, such as nuts and eventually washers that are arranged such as to form unilateral constraints both above and below a moving portion 43 formed by the profile of the second cam 19 ( Fig. 3 ).
  • the translations of the stem 26 can be converted into rotations of the second cam 19.
  • the second release means advantageously comprise cable means connected to the second cam 19 as well as with a lever 27 that interacts with an emergency valve 33 for the main cylinder-piston unit 10 such that, in response to an actuation of the cable means, the emergency valve 33 empties the main cylinder-piston unit 10 and the second cam 19 releases the first cam 18 and thus the upright 12.
  • These cable means advantageously comprise a cable 30 that passes through the release cylinder-piston unit 25 in a substantially coaxial manner.
  • This cable 30 is fastened at the end of the stem 26 by means of a first stop 31 and at the end 28 of the lever 27 by a second stop 32, such as to be held tensioned.
  • a kinematic chain is provided such that, when the lever 27 is rotated counter-clockwise, the stem 26, which is pushed by the cable 30 operated by the lever 27, moves downward and consequently the second cam 19 rotates counter-clockwise thus releasing the first cam 18 (release position).
  • This mechanism is advantageous when pressure is absent in the pneumatic circuit and the release cylinder-piston unit 25 has to be operated in a manual, rather than pneumatic, manner for allowing an emergency opening of the door 2.
  • the lever 27 comprises a projecting portion 35 that is positioned and oriented such that, when the lever 27 is operated, i.e. rotated counter-clockwise, to allow for the emergency opening, the projecting portion 35 presses a push-button 34 of the emergency valve 33, thus activating the latter and consequently emptying the main cylinder-piston unit 10 from the residual air provided within the lower chamber thereof, and allowing the upright 12 to be completely moved downward.
  • the second release means comprise one or more emergency handles 36 ( Fig. 3 , 7 , 8 ), preferably one to be positioned outside and one to be positioned inside the vehicle.
  • These emergency handles 36 are connected to the lever 27, preferably by means of as many emergency cables 37 passing through a drilled plate 38 fixed to an upper edge of the vertical portion of the L-shaped plate 14. Thereby, when the emergency handle 36 is acted upon, the lever 27 will be operated thus taking the second cam 19 in the release position due to the kinematic chain provided by the cable 30.
  • the blocking means 7 further comprise selective blocking means suitable to prevent the door 2 from being opened in manual manner by means of the emergency handles 36 when the vehicle speed is higher than a minimum speed ( Fig. 6 ).
  • These selective blocking means advantageously comprise a pneumatic single-acting safety cylinder 39, with a stem 40 that, in the presence of pneumatic power supply, is engaged within a seat (not shown in the figures) of the second cam 19 being provided at the moving portion 43 thereof. This engagement prevents the second cam 19 from rotating counter-clockwise, such that the cam 19 does not move to the release position when one of the emergency handles 36 is acted upon.
  • the pressurized air supply to the safety cylinder 39 is closed and the stem 40 thereof is elastically retracted thus releasing the second cam 19. Since the safety cylinder 39 is single-acting, the stem 40 is retracted even in case of accidental failure of the pneumatic supply circuit, thus allowing for the emergency opening of the door 2.
  • the lower chamber of the main cylinder-piston unit 10 is filled of pressurized air, such that the stem 11 thereof and the upright 12 are in the lifted position.
  • the release cylinder-piston unit 25 is maintained emptied, such that the lifting member and thus the stem 26 thereof are fully lifted and that the first and second cams 18 and 19 are mutually engaged in the blocking position (door closed).
  • the fall of the upright 12 caused by the pressure loss within the lower chamber of the main cylinder-piston unit 10 is prevented by the support projection 21 of the first cam 18, which abuts against the plate 23 of the upright 12.
  • pressurized air is provided to be blown to the lower chamber of the main cylinder-piston unit 10, such that the upright 12 moves upward.
  • the first cam 18, which is free of the forces transmitted by the plate 23, rotates clockwise due to the elastic action of the spring 20.
  • the second cam 19 rotates clockwise due to the elastic outward movement of the stem 26 of the safety cylinder 25, not powered, until the lock portion 24 of the second cam 19 engages the corresponding recessing seat 22 of the first cam 18, thus ensuring that the downward movement of the upright 12 is blocked.
  • the door 2 is opened by acting on one of the emergency handles 36, which tensions the emergency cable 37, which causes the lever 27 to rotate counter-clockwise.
  • the lever 27, by acting on the cable 30, causes the stem 26 of the release cylinder-piston unit 25 to move inside.
  • the second cam 19 rotates counter-clockwise thus releasing the cam 18.
  • the projecting portion 35 of the lever 27 acts on the push-button 34 of the emergency valve 33, that sets the main cylinder-piston unit 10 to discharge.
  • the upright 12 which is subjected only to the weight force, is free to move downward, thus allowing for the emergency opening of the door 2.
  • actuating device according to the invention can be converted, by means of simple operations, to the configuration not provided with a blocking system, and vice versa, by simply removing and reconnecting the auxiliary support plate to which the blocking and release means are connected.
  • auxiliary support plate is the only portion of the actuating device which requires to be processed in view of the assembly of the blocking means and release means.
  • the L-shaped support plate to which the auxiliary support plate is applied requires only professing suitable to allow this connection and not processing aimed at mounting the blocking and release means (cams, rollers, levers, cylinders, valves). Consequently, the design and manufacture of the actuating device in the two versions can be unified, since the auxiliary support plate is the only component subjected to extra processing, which is constructively independent from the remainder of the actuating device.
