Definitions

  • the present invention relates to a door system with at least one door leaf, which closes and opens a door opening, and an extendable sliding step arranged below the door opening.
  • Sliding steps are used in door systems for passenger vehicles to make it easier for people to get on and off. Such sliding steps are also referred to as extensions, tread plates or gap bridging and have a resilient and walkable tread surface.
  • the sliding step can be arranged, for example, in a frame as a receiving device, which is firmly connected to the vehicle.
  • Door systems of public passenger vehicles usually have one or two door leaves. These can be designed as sliding doors or pivoting sliding doors.
  • the sliding steps are usually arranged below the door opening and the door leaf.
  • the usual sequence of movements of the door leaves and the sliding step is serial, during the opening process the sliding step first moves from its retracted end position to the extended extended position before the door leaves open.
  • the sequence of movements is reversed, first the door leaves close, then the sliding step is moved to its end position.
  • parallel or quasi-parallel methods are also known, in which the movements of the door leaves and the sliding step are essentially synchronous.
  • the object of the present invention is to propose a door system which avoids the disadvantages of the prior art.
  • it should be ensured that the sliding step is always retracted when the door leaf is closed.
  • the structure should be as simple as possible and the effort for maintenance and repair should be as low as possible.
  • the sliding step is arranged in its retracted end position in an extension direction of the sliding step behind the at least one door leaf and is covered by this, the sliding step being designed and arranged in such a way that the door leaf makes contact with the sliding step via contact surfaces during its closing movement and drives it into its end position .
  • the sliding step In its retracted end position, the sliding step is thus covered by the sliding step and locked in the retracted end position.
  • the door system according to the invention can have sliding doors or pivoting sliding doors.
  • the door leaf moves only in the direction of the vehicle's longitudinal axis or parallel to the outer wall of the vehicle; in the case of a pivoting sliding door, the door leaf also moves in the transverse direction.
  • the wording "in the direction of the longitudinal axis of the vehicle” is used below, but always includes the direction "parallel to the outer wall of the vehicle". This is relevant in cases where the doorway is located, for example, on the front or rear.
  • the invention is suitable for door openings that are only closed by a single door leaf, but in particular also for door systems with two door leaves. The invention is explained below by way of example for use with two door leaves, but is not limited thereto.
  • the sliding step is moved into its end position by the door leaves, it does not require its own drive for this.
  • the closing door leaves come into contact with the sliding step via contact surfaces and press it into its end position, i.e. push it in front of you.
  • the contact surfaces can be arranged, for example, in corner areas at the free end of the sliding step, but an arrangement on a free front side of the sliding step is also possible.
  • the door leaves moving in the longitudinal axis of the vehicle first hit the sides of the sliding step, or contact surfaces arranged there, running transversely to the longitudinal axis of the vehicle.
  • the contact surfaces are designed in such a way that the force applied by the door leaves and acting in the longitudinal axis of the vehicle is converted into a driving force that acts in the transverse direction to the longitudinal axis of the vehicle. This is achieved, for example, by contact surfaces running obliquely in relation to the longitudinal axis of the vehicle. In the case of sliding doors, such contact surfaces are sufficient to be able to close the door leaves completely.
  • the contact surfaces on the sliding step can also be arranged on the free front side.
  • the door leaves therefore first move past the front side of the sliding step, then make contact with the front side at the moment when they enter the door opening in the transverse direction to the longitudinal axis of the vehicle.
  • a combination of the arrangement of the contact surfaces is also possible.
  • Door leaves of pivoting sliding doors then first contact the sides of the sliding step, which is then moved towards its end position along inclined contact surfaces in the transverse direction of the longitudinal axis of the vehicle.
  • Contact surfaces on the front side of the sliding step connect to the inclined contact surfaces, which are contacted in the last phase of movement of the door leaves.
  • a locking unit is additionally provided, which locks the sliding step in its end position, so that it remains in its end position when the door system or the door leaf is opened and is not extended.
  • the locking unit can also lock the sliding step in its extended position, resulting in a stable step situation for passengers.
  • the sliding step has a drive that moves it from its end position to its extended extended position.
  • the drive is formed by one or more spring elements, which then move the sliding step out of its end position when the door leaves release it or the contact surface. Conversely, the spring force when closing the door leaves must be overcome when the sliding step is pushed back.
  • the spring elements are preferably arranged within the housing of the sliding step in the rear area and are supported against a rear side of the housing frame.
  • Other positions are conceivable, particularly depending on structural restrictions.
  • a cable can also be used as a drive. Accordingly, a rope is connected to at least one door leaf, so that the sliding step is moved, preferably pulled, out of its end position when the door leaf is opened.
  • the cable of the drive can be deflected via appropriate deflection pulleys in order to enable movement in the transverse direction of the longitudinal axis of the vehicle.
  • a roller is preferably driven, on which the cable rolls up again.
  • spring elements are suitable as spring elements for driving the sliding step, in particular compression springs, but also tension springs. Spiral springs, leaf springs, but also elastomers are conceivable. Ultimately, it is essential that the spring element provides a sufficient force component in the extension direction of the sliding step.
  • figure 1 shows a door system 20 according to the invention, having two door leaves 22 and a sliding step 24 which is arranged in the floor area 26 of a door opening 28 .
  • figure 1 shows an interior view with closed door panels 22. It can be clearly seen that the sliding step 24 is arranged inside the vehicle behind the door panels 22, so the door panels 22 cover the sliding step 24 in the closed position, it is not visible from the outside.
  • the sliding step 24 is preferably covered by a cover plate of the floor area 26 that can be walked on.
  • the sliding step 24 has a front side 30 pointing in the direction of the outside of the vehicle and correspondingly two side edges 32 running transversely to a longitudinal axis XX of the vehicle.
  • the sliding step 24 can be moved in the transverse direction YY to the longitudinal axis XX of the vehicle, it is located in figure 1 with its front side 30 on the two door leaves 22.
  • figure 1 shows the retracted end position of the sliding step
  • figure 3 shows the door system 20 in cross section from above.
  • the door leaves 22 are partially open, the sliding step 24 is already partially extended.
  • the two arrows drawn in indicate the direction of movement of the door leaves 22, in particular also the extension direction of the sliding step 24.
  • the door leaves 22 move out of the door opening 28 in the transverse direction YY and then move laterally on the vehicle in the vehicle longitudinal axis XX.
  • the sliding step 24 has two contact surfaces 34 in its free corner regions, each of which makes contact with a door leaf 22 .
  • the door leaves 22 have already been extended out of the door opening 28 in the transverse direction and the sliding step 24 has followed correspondingly due to the spring loading.
  • FIG 2 shows the sliding step 24 without a cover plate.
  • Two spring elements 36 can be seen, which are arranged on a transverse frame element 38 of a housing frame 40 of the sliding step arranged inside the vehicle.
  • the spring elements 36 are designed as compression springs which contact the sliding step 24 at its rear edge 42 and thus move it through the door opening 28 when the door leaves 22 are open. Accordingly, the spring force of the spring elements 36 must be overcome when the door leaves 22 are closed and when the sliding step 24 is pushed in.
  • a locking unit 44 is also provided, which is also arranged inside the housing frame 40 .
  • the locking unit 44 can be used to lock the sliding step in different positions. It makes sense, for example, to lock the sliding step 24 in its retracted end position when it is not necessary to extend the sliding step 24 due to the external conditions. However, the sliding step 24 can also be locked in the extended extended position in order to ensure a more stable step. Ultimately, however, intermediate positions in the area of the travel path can also be locked if this should make sense, for example, due to the distance of the vehicle from the platform.
  • the contact surfaces 34 can be formed by rollers in order to enable the sliding step to be extended and retracted more gently and with less wear.
  • the sliding step 24 can also have inclined surfaces as contact surfaces 34 in order to contact retractable door leaves 22 parallel to the vehicle longitudinal axis X-X and to deflect their force into a component in the transverse direction Y-Y.
  • figure 4 12 shows the door system 20 in a perspective view from above, with the door leaves 22 not being shown and the sliding step 24 being in the fully retracted position.
  • FIG. 5 shows the doors 20 according to the invention from above in a greatly simplified basic representation with open door leaves 22 and extended sliding step 24.
  • a platform 46 and a gap 48 which is arranged between the platform 46 and an outside 50 of the vehicle, can also be seen.
  • the sliding step 24 is in the extended extended position and extends across the gap 48 .
  • the spring elements 36 have moved the sliding step 24 into the extended position.
  • the door leaves 22 are closed, they make contact with the contact surfaces 34 and push the sliding step 24 back into the housing frame 40 into the interior of the vehicle as it continues to move.
  • the sliding step 24 is then located behind the door leaves 22.
  • the invention is not limited to the exemplary embodiment shown, but also includes other variants that make use of the inventive idea.
