Definitions

  • the invention relates to an emergency actuation device according to the preamble of claim 1 for a vehicle door operated by means of a non-self-locking electric drive, the connection from the door drive to the door transmission being designed to be self-locking at least in the closing end region of the door.
  • door drive means the motor and the reduction gear cooperating with it and other components up to the component on the motor side that is involved in the self-locking, the component that overcomes the self-locking during motor operation still being counted as a door drive.
  • the door gear includes all of the components located on the door side up to the attachment to the door.
  • Such a door is known from European Patent Application No. 84101874.0 by Kiekert GMBH & CO KG, published under No. 0118081.
  • the self-locking takes place by overcoming a dead center of a curved rod of the door gear.
  • To facilitate the emergency operation it is proposed to bring the motor and the gear out of engagement with the rest of the door drive and the door gear and then to bring this component group manually out of the self-locking area by means of a Bowden cable. To do this, however, a considerable amount of force must be exerted, which depends on the pre-tensioning of the door system and on the size of the breakdown position of the dead center lock.
  • a door of the type mentioned with an electric linear drive is described in the not yet published European patent application No. 87890113.1 by the applicant. It is provided in the case of emergency actuation that the door drive, including the self-locking part of the door gear, is disengaged from the rest Bring part of the door gear, which makes the door easy and easy to open.
  • the door drives are installed vertically according to the AT-PS and the door drive and the door gear does not provide any appreciable resistance to a door movement if the pressure drops as soon as the area of self-locking is left.
  • the drive is installed horizontally and the electric linear motor - usually a ball screw drive - has a poor mechanical efficiency over its entire path of movement, which makes it impossible to disengage the door from the self-locking area by hand.
  • a slide acting on the door drive in the opening direction in the area of the closed end position of the door gear, the displacement path of which is greater than the self-locking area of the door drive-door gear connection, that the slide is held by a holding device in a position corresponding to the closed end position of the door, and that the holding device can be released by hand.
  • This measure makes it possible to use a spring, an air cushion or the like to slide the slide. to be acted upon with such a force that it is possible to reliably leave the self-locking area.
  • This disengagement force is only limited by the closing force of the electric linear drive, since after an emergency operation of the door when the door is automatically closed for the first time, the slide is carried by the door drive in the closing direction until the end position is reached against the disengagement force, whereupon the slide is again held by the holding device recorded and held in this position.
  • the closing force of the door drive must therefore be greater than the disengaging force, at least in the closing end region, the friction and inertia forces that have to be taken into account.
  • the displacement path must be sufficiently large to ensure that it leaves the self-locking section of the door movement. How long this path actually is depends on where the slide engages the door operator and whether there is a translation between the point of application and the area of self-locking.
  • the displacement path can of course also be an angle of rotation or can be specified as such if the slide engages a rotating part or itself executes a rotary movement.
  • FIG. 1 shows a device according to the invention
  • FIG. 2 shows a holding device according to the invention.
  • An electric motor 1 drives a linear drive 2 with poor mechanical efficiency. This moves a piston rod 3 back and forth, a roller 4 rotatably arranged on this piston rod sliding in a link 5.
  • the link 5 is arranged rotatably about an axis 6 and actuates one or more doors when the piston rod 3 is displaced via a mechanism (not shown).
  • the setting 5 is designed so that it runs at least approximately parallel to the axis of the piston rod 3 with the section in which the roller 4 is located at this time when the door is closed.
  • a pressure plate 11 is provided on the piston rod 3, against which a slide 12 can press in the opening direction of the piston rod 3.
  • This slide is under the action of an energy accumulator, which is loaded by the drive 1, 2 when the door is closed.
  • the slide 12 is held in place by a holding device 13, so that after the door has been closed, when the drive 1, 2, as is customary in the case of electrically operated doors, is switched off and thus becomes weak, the door 5 is locked by the self-locking of the link 5 remains closed.
  • the door In the event of a power failure, the door must be able to be operated by the user in spite of the self-locking of the setting, without the power of the drive 1, 2 being available.
  • he operates a Bowden cable 14, whereby the holding device releases the slide 12 and, under the action of the energy accumulator, it is pressed against the pressure plate 11 of the piston rod 3, which subsequently moves it in the opening direction, as a result of which the roller 4 moves out of the self-locking area of the link 5 reached.
  • actuation of the switch 21 no longer causes the lifting of the motor short-circuit (infinite resistance), but increasing the motor resistance by a finite value, which means that the door can be opened more easily than with a short-circuited motor, but more difficult than with an open motor short-circuit.
  • the emergency operation can be ended in various ways, for example by resetting the Bowden cable, in which case the drive is supplied with current again by a switch (not shown) connected to the handle of the Bowden cable and a closing movement of the door is initiated.
  • a closing movement of the door is initiated.
  • the working memory 15 is “loaded” and the holding device 13 fixes the slide 2. The door is thus again in the normal operating state.
  • the invention is not limited to the illustrated embodiment, but can be modified in accordance with claim 1.
  • the backdrop can have a different shape and the section of the door movement in which self-locking occurs can be larger or smaller than in the selected example. However, it is important that the disengagement path of the slide 12 ensures that the self-locking area is left safely.
  • the holding device can be designed differently, and in order to ensure reliable detection of the slide, the stopping point can be arranged at a short distance from the closed end position of the door that is reached by motor. When choosing this distance, care should be taken to ensure that when the door drive is properly switched off after the door is closed, it is lifted by the slide until the stop point is reached. This point, which thus represents the final closed position, must meet all safety and sealing conditions. Furthermore, the surfaces interacting between the slide 12 and the holding device 13 can be arranged or coated accordingly to enable easy release and snapping of the holding device, which can be significant with large forces stored by the spring 15.
  • the Bowden cable 14 can be designed by means of a spring so that it returns to its starting position when its handle is released. As a result, an automatic return to normal operation without special switching is possible after the fault has disappeared.
  • the invention can also be applied to door drives according to EP-A2 0118081 if a corresponding torque is exerted by the energy accumulator on the disk carrying the two bent levers.
