Definitions

  • the invention relates to a door lock for doors of aircraft, in particular of helicopters according to the preamble of claim 1.
  • Such doors are known for the approach of the pilot formed as gullwing doors. Unlike land vehicles, the doors which are provided there within the openings provided in the fuselage structure must be absolutely securely closed - infiltrated - in aircraft, whereby so-called gas pressure springs are generally provided for the necessary sealing between door and door opening.
  • the doors of a helicopter make the first contact with the aircraft and thus determine the first impression to the respective user. There is therefore a requirement that doors are self-explanatory of their operability and function and do not already constitute the first manual and / or technical obstacle when entering the helicopter.
  • the functions of the door lock should also be understandable and logical without additional signs and instructions for everyone.
  • a generic, all features of the preamble of claim 1 having door locking device for doors of helicopters is available for the helicopter Eurocopter EC 135 as an optional extra and in use.
  • DE 103 59 737 A1 discloses a device for locking a front hood of a motor vehicle.
  • the device has at least one
  • Main closure and at least one additional closure each one Include rotary latch with pawl and lockable by the catch in the closed position of the front cover closing member.
  • the closing member of the additional closure is designed so that when unlocked main closure only after a desired opening stroke of the front hood uses a locking action between closing member and rotary latch of the additional closure.
  • a disadvantage here proves that in Vorrastsander, ie after activation of the catch between the front hood and body remains a gap.
  • the invention is therefore an object of the invention to provide a new door lock device that is better than previously operated while maintaining the security lock.
  • the new door lock is surprisingly advantageous.
  • Wedge surface and catch level of the pivoting wedge are arranged at its end faces of catch and locking hooks facing effective surface, which acted upon by a torsion spring with respect to its bearing pin 5 in the counterclockwise pivoting wedge, as soon as the catching stage is in operative connection with an extension of the fishing hook, this in his in situation reached to stop pin position locks.
  • the inventive design of the door lock facilitates the safe 10 closing of such doors considerably and therefore significantly increases the ease of use for the crew of a helicopter.
  • 1 is an isometric view of a specific for a gullwing door of a helicopter locking device according to the invention, 20th
  • FIG. 2 is a plan view of the locking device of FIG .. 1
  • Fig. 3 is a side view of the locking device of FIG. 1 in the direction of the arrow A r. 5
  • Fig. 4 is a side view of the locking device of Figure 1 in the direction of arrow B with the locking members supporting support plate and 0
  • Fig. 5 is a side view of the locking device of FIG. 1 in the direction of arrow C.
  • a locking device for the wing door also not shown, of an aircraft, also not shown, in particular a helicopter, is shown in Figs. 1 to 5, only one of the hinged door firmly connected locking devices 10 which are actuated via a likewise not shown a hand lever exhibiting linkage and each cooperate with a fitting attached to the fuselage structure of the aircraft serving as a catch 11.
  • Each of the locking devices 10 has an angular support plate 12, whose angled by about 90 ° part forms a flange 13 which is obliquely - see Fig. 4 - arranged to the approximately horizontal plane of action of the locking device.
  • the respective locking device is attached to the wing door of the helicopter by means of screws, not shown here.
  • the flange 13 carries a bearing pin 15 for a pivotally mounted pivoting wedge 16, which is acted upon by a torsion spring 17 in the counterclockwise direction cf.
  • a plate-shaped extension 18 of the support plate 12 carries a bearing pin 19 for receiving the locking members to be described and has at its free end to the bolt 20 of the catch 11 facing slot-shaped opening 22.
  • the trailing edge 23 of the slot-shaped opening 22 serves as a stop and thus as a limitation of the movement of the hinged door in its closed position.
  • the pivoting wedge 16 engages through an opening 24 provided in its region in the extension 18 of the carrier plate 12 into the pivoting range of the locking members to be described.
  • the pivot wedge 16 has the purpose of leadership in the opening 24 of the pivot wedge 16
  • Support plate 12 has a lateral extension 26 which forms a common wedge surface 28 with the end face of the free end of the pivoting wedge; see. FIG. 5.
  • the said locking members comprise a catch hook 30 designed as a two-armed lever and adjacent thereto a locking hook 31, which also acts as a two-armed lever, acts as a so-called rotary latch and acts as a rotary latch - which are pivotally mounted on the bearing pin 19 of the support plate 12.
  • a Torsionsfeder 34 acts on the fishing hook 30 in a clockwise direction with respect to the bearing pin 19 - see. Figure 1.
  • the movement of the fishing hook 30 in the counterclockwise direction is limited by a stop pin 32 which is fixed in the plate-shaped extension 18 of the support plate 12.
  • the catch hook 30 has at its the bolt 20 facing the free end to a downwardly directed slot-shaped opening 36, the bolt facing the boundary terminates in a wedge surface 37.
  • the opposite lever arm of the fishing hook carries a support plate facing extension 38 which cooperates with the catching step 29 of the pivoting wedge 16; see.
  • the bolt 20 facing the free end of the two-armed locking hook 31 also has a slot-shaped opening 39, which merges at its free end in a wedge surface 40; see. Figure 3.
  • the said wedge surfaces 36 and 39 of the associated locking members, namely the catch hook 30 and the locking hook 31 support the catching and locking movement of the locking members in the clockwise direction about their bearing pin on the bolt 20 as soon as the hinged door by hand in a position close to the closed position is transferred.
  • the remote lever arm of the locking hook 31 carries a provided with a ball head 42 bearing pin 43 - see.
  • Figure 2 - which projects by means of a bushing 44 in the pivoting range of catch and locking hooks, as well as in the region of the wedge surface 28 of the pivoting wedge 16 in order to move them, as will be described.
  • the operation of the locking device described above is as follows:
  • the catch lever 30 is pivoted over the wedge surface 28 by the bolt 20 with respect to FIG. 3 in the clockwise direction around the bearing pin 19 against the action of the spring 34 by a small angle.
  • the catch hook with its opening 36 of a lever arm, the bolt 20 and moves with its other lever arm facing away from the pivot wedge 16 by means of its extension 38 - Figure 2 - against the action of the spring 17 in a clockwise direction until the lock position shown is reached in the Schenkkeil 16 and fishing hooks 30 are locked on the catching step 29 of the pivoting wedge and the attacking there extension 38 of the fishing hook.
  • the hinged door is held in the position just taken, so is "trapped".
  • the locking hook 31 is moved about the bearing pin 19 with respect to FIG. 3 in the clockwise direction, so engages this with its slot-shaped opening 39th now completely the bolt 20 and locks with simultaneous tightening of the door leaf in the door opening within the fuselage structure of the helicopter, this in the closed position.
  • the locking hook 31 carries, as already mentioned, at its free lever arm the bolt 43 with the ball head 42, which is in operative connection with said linkage for locking the door.
