Definitions

  • the invention relates to a sliding door device, in particular for a vehicle such as a railroad car, a trailer or a truck.
  • the sliding doors are guided and stored on their bottom and top along guide rails by means of drives.
  • the guide rails run straight, so that the sliding door can be pushed aside with minimal effort.
  • the sliding door can be displaced in a plane which is displaced forwards in relation to the side wall.
  • the sliding door cannot therefore be sunk into the wall opening in the side wall in order to achieve optimal sealing of the wall opening and to align the outside of the sliding door coplanar with the side wall of the vehicle.
  • guide rails are provided which run in a first rail section in a first plane and in a second rail section in a second plane. Between the first and the second rail section, the rail sections are connected to one another by rail curves that typically run in an S-shape. The sliding door or pivoting sliding door is transferred from the first rail section to the second rail section and is extended out of the wall opening.
  • Pivoting sliding doors are regularly provided in railway carriages, which are unlocked in a first step, pivoted out of the plane of the side wall of the railway carriage out of a wall opening in a second step, moved into a plane in front of and parallel to the side wall of the railway carriage in a third step and in a fourth Step to the side in this level in front of the side wall of the railroad car.
  • the pivoting sliding door is locked and swiveled out and extended independently of one another.
  • a door device with a pivoting sliding door which can be displaced laterally from a wall opening in a closure plane which runs coplanar with the side wall of the railway carriage into a displacement plane which is parallel thereto and which is spaced in front of the side wall of the railway carriage.
  • This door device comprises a pivoting mechanism, by means of which the edge of the pivoting sliding door leading in the direction of travel can be pivoted out of the wall opening and can be driven and displaced in the direction of travel.
  • the leading edge of the extending pivoting sliding door is coupled to a running rail that connects to the wall opening and runs parallel to the side wall of the railway carriage.
  • the pivoting mechanism includes a carriage that is guided in a guide rail that is integrated into the pivoting sliding door.
  • the pivoting sliding door comprises a further carriage which can be inserted into the running rail which adjoins the wall opening.
  • the rear edge of the pivoting and sliding door is guided by an S-shaped guide rail, which has a first rail section in which the rear edge of the pivoting and sliding door lies in the locking plane and through an S-shaped curved section with a second Rail section is connected, in which the rear edge of the pivoting sliding door is in the sliding plane.
  • a locking mechanism is to be provided, by means of which the sliding door can be locked.
  • a pivoting mechanism is to be provided, by means of which the sliding door can be pivoted at the front.
  • a first guide rail which is integrated in the pivoting sliding door, and a second guide rail, which adjoins the wall opening, are to be provided.
  • the S-shaped guide rail is to be provided, along which the rear edge of the pivoting sliding door is guided.
  • the pivoting mechanism can be coupled to a drive motor, by means of which the pivoting sliding door can be displaced from the closed position or the closed plane into the displacement plane.
  • the door frame must be designed in accordance with the displacement path of the pivoting sliding door or the S-shaped course of the guide rails, which leads to restrictions in the development of such systems. Furthermore, special expenses are required to ensure a high level of tightness of the closed door.
  • the US4142328A discloses a sliding door assembly having a sliding door for closing off a wall opening in a side wall of a railroad car.
  • the sliding door is slidable along an upper and a guide rail and is supported by two crankshafts, each connected via a connecting element to a drive lever, by means of which the crankshafts can be shifted in order to move the sliding door relative to the wall opening.
  • the crankshafts are each connected to a locking rod which, after the wall opening has been closed, is inserted into locking openings in the side wall.
  • the door device and the mechanism for locking and opening the sliding door should be simple in design.
  • the door device should be easy to mount on the vehicle, so that vehicles already in operation can also be retrofitted with the door device according to the invention, if necessary.
  • the sliding door should be able to be operated manually with little effort. With just one manual movement by the user, the sliding door should be able to be unlocked and made ready to slide parallel to the side wall or brought back into the closed position and locked at one or more points. The unlocked sliding door should also be able to be pushed to the side with minimal effort. Overall, this should result in maximum ease of use.
  • the wall opening In the closed position of the sliding door, the wall opening should be tightly closed.
  • the device for sealing the sliding door should be of simple design. In this regard, the door device should make no or only minor demands on the design of the sealing device.
  • the sliding door should be allowed to have any external shape, for example surface portions that are inclined towards one another.
  • Sliding doors can be used in side walls of vehicles, which run parallel to one another in a lower part and in opposite directions in an upper part.
  • the sliding door device comprises a sliding door for closing off a wall opening, in particular a wall opening in a side wall of a vehicle, such as a railway carriage, a trailer for road vehicles or a truck.
  • a sliding door device can also be used advantageously for closing off a wall opening in a building.
  • the sliding door is laterally slidable along an upper guide track and a lower guide track between a closed position in which the wall opening is closed and an open position in which the wall opening is exposed.
  • the sliding door is connected at the top to at least one upper carriage, which is slidably held by the upper guide rail, and at the bottom to at least one lower carriage, which is slidably held by the lower guide rail.
  • the sliding door comprises at least one actuating mechanism, by means of which the sliding door can be locked in the closed position.
  • the actuating mechanism serves to actuate at least one displaceably mounted Locking bar intended to lock the sliding door.
  • the actuating mechanism By actuating the at least one locking rod, the actuating mechanism thus sequentially fulfills two functions in a sequence of movements, which is mechanical can be advantageously implemented.
  • the at least one locking rod By actuating the at least one locking rod, which is retracted into or extended from a locking part in the door frame, for example, the sliding door is locked or unlocked on the one hand.
  • the crankshafts are rotated via the coupling device in order to bring the sliding door into the locking position before the sliding door is locked or to extend the sliding door out of the locking position after the sliding door has been unlocked.
  • the coupling device provided for each crankshaft comprises a gear wheel held by the crankshaft and a toothed rack held by the associated locking rod, which are arranged in such a way that they engage with one another when the locking rod is displaced along the locking path, so that by moving the Closing rod the associated crankshaft can be rotated forwards or backwards and the unlocked sliding door can be slid frontally.
  • the toothed rack is preferably arranged on the locking rod in such a way that the toothed rack is only in engagement with the gear wheel when the sliding door is not locked.
  • the locking section of the at least one locking bar is therefore preferably divided into two sections. Within the first leg, the at least one locking rod is coupled to the crankshafts to drive the sliding door against the wall opening. In the second section, the at least one locking rod is decoupled from the crankshaft and can be moved into and out of a locking part in the door frame.
  • the actuating mechanism can therefore have a simple design and can only be provided for actuating or displacing one locking rod or preferably two locking rods.
  • both crankshafts are thus rotated in order to displace the sliding door held in front of the wall opening relative to the wall opening.
  • the actuating mechanism is preferably connected on both sides to a locking rod which is provided with a toothed rack.
  • Each locking rod can therefore actuate one of the crankshafts and then move into a locking part in the door frame at the front.
  • the locking rods are preferably mounted in an axially displaceable manner corresponding to their cross section.
  • Relatively thin plate-shaped locking rods with a rectangular cross-section are preferably provided, into which at least one toothed rod can advantageously be inserted.
  • the actuating mechanism thus fulfills the task of displacing the at least one locking rod, preferably axially back and forth, and can be driven for this purpose by means of a drive motor or else manually by means of an actuating lever. Due to the simple design of the sliding door device, both Drive options are advantageously realized. If the actuating mechanism has a centrally arranged lever or a central lever, the drive motor or the actuating lever can act directly on it. The drive motor can act directly or via a gear on a central shaft, which holds the central lever. In both drive variants, the central lever can be rotated back and forth around the central shaft.
  • the simple axial displacement of the locking rod can also be effected by means of a spindle, which is driven in a simple manner by a motor directly or via a gear.
  • the lever system thus makes it possible to couple the rotatably mounted central lever to the axially displaceable locking rods.
  • the actuating lever is from a first end stop in the closed position, in which the locking rod is extended along a locking section and retracted into a locking part in the door frame at the front, to a second end stop in the open position the locking rod is withdrawn from the locking part and retracted along the locking path, displaceable or rotatable.
  • the actuating lever can preferably be locked or locked in the closed position and/or in the open position by means of a closing means or locking means.
  • the locking means or locking means which correspond to one another are preferably mounted on the actuating lever and on a mounting plate which also holds the central lever.
  • the guide rails can run in a straight line, allowing the unlocked sliding door to be slid with minimal effort to reveal the wall opening.
  • straight guide rails also makes it possible to equip existing vehicles with a sliding door device according to the invention with relatively little effort.
  • the guide rails can be easily mounted and the required degree of frontal displacement of the sliding door in front of the wall opening can be achieved by appropriately selecting the articulated levers.
  • the door device according to the invention is therefore excellently suited for vehicles in which the highest demands are placed on thermal insulation.
  • the sliding door is preferably connected to the upper ends of the crankshafts by upper attachment fittings and to the lower ends of the crankshafts by lower attachment fittings.
  • the upper and/or lower attachment fittings hold the crankshafts in a rotatable but axially immovable manner.
  • the sliding door is thus supported by the crankshafts, which in turn are rotatably connected to the lower and upper carriages.
  • the weight of the sliding door can be over the top mounting kits or the lower mounting kits or the top and lower fastening sets are transferred to the crankshafts.
  • the sliding door has a peripheral mounting frame on which the upper and lower fastening sets are mounted and into which a one-part or multi-part and single-layer or multi-layer door leaf is inserted.
  • the mounting frame actually forms the vehicle chassis of the sliding door, on which device parts such as the fastening sets, bearing devices for mounting the crankshaft and the at least one locking rod, the operating mechanism and the preferably multi-part door leaf can be stably mounted.
  • the mounting frame of the sliding door is accordingly adapted to the door frame that encloses the wall opening and, if necessary, additionally provided with sealing elements.
  • crankshafts for example, run straight in a first sub-area, optionally aligned vertically.
  • the at least one locking rod is typically mounted so that it can be displaced horizontally and is preferably aligned perpendicularly to the associated crankshaft.
  • the crankshafts preferably run according to the inclination or inclination and curvature of the sliding door.
  • crankshafts can follow the course of the curvature and inclination of the sliding door within the cross-section of the sliding door, the crankshafts preferably comprise crank joints that allow the direction of the drive axis to be changed accordingly.
  • the upper and lower universal shafts by which the linkages fixedly connected to the crankshafts are rotatably supported, are preferably of upper and lower mounting parts of the upper and lower carriages aligned parallel to or coaxial with one another. In this way, the sliding door always performs a horizontal movement when opening or closing, which requires only a small amount of force. If, on the other hand, the articulated shafts, which are aligned parallel to one another, are inclined, an increased expenditure of energy may be required during opening or closing, which is available again for the reverse process of closing or opening.
  • FIG. 1 shows a railroad car 1 without running gear or bogie.
  • On the opposite side walls 15, 15 'of the railroad car 1 wall openings 10, 10' are provided, each with a door device according to the invention, for example according to Figure 2a and Figure 3a can be provided.

  • the crankshafts 3 comprise simple connecting rods 33, which are held in position by means of shaft bearings 30 so that they can rotate.
  • the two crankshafts 3 are each firmly connected to the assembly frame 21 of the sliding door 2 by upper attachment fittings 29 and lower attachment fittings 28 .

  • FIG. 12 further shows that the sliding door is covered by a door panel 22.
  • the door panel 22 comprises two spaced layers that enclose the crankshafts 3 within the cross-section of the sliding door 2 . It is shown that the door panel 22 can include multiple segments.
