Description

The invention relates to a sliding door of a railroad car for passenger traffic.

The rail-bound traffic, u. between both goods and especially for people, is increasing in importance, whereby not only the Local transport, but always over long distances attained greater economic importance. The cause of this there is that in addition to logistical measures, both the track and the rolling stock can also be designed to be larger To reach speeds. This is what freight trains are like at top speeds from 120 km / h to 140 km / h in the range of possible. Passenger trains are used for even higher speeds, e.g. B. 140 km / h to 160 km / h, even in individual cases over 200 km / h, designed. At these high speeds the requirements for the track as well as the rolling Material getting stronger in two different directions. On the one hand security and low noise pollution must be outside of the means of transport must be guaranteed, and on the other hand must have security within the means of transport guaranteed for the transported goods or persons transported become. Additional requirements for the rolling stock consist in maintaining the lowest possible weight is and that for logistical reasons a railway wagon should be as universal as possible. For example not a separate wagon at the beginning or end of a train be required to appropriately trained end faces of the wagon ensure which particularly strong pressure or Are subject to negative pressure. As a test print is used for testing 3,000 Pa. Furthermore Such end faces are said to be redundant security systems to have in the event of failure of a locking device Security to prevent the doors from opening.

From the contribution by P. Fabel et. al. ZEV-GLASERS ANNALEN, Volume 112, No. 1, January 1988, pages 33 to 35, becomes one front wall door, which is known as Sliding door is formed. This sliding door points inflatable seals, so that they can first and last wagons of a train are used can. A door mat is used to secure the passage intended.

In BE-A1 550962 there is a sliding door for transportation described an actuating mechanism having. A latch is over a handle can be actuated by a fixation of the door Should enable closed position. This bar points two surfaces, the one in the closed position of the bolt a limited fixation of the door across the opening and Closing direction allows. With an unlock also the cross securing of the sliding door is removed.

From EP 0 312 450 A, a swivel sliding door on railway wagons known with an in addition to the locking device provided cross protection against perpendicular to Door leaf attacking forces, and with an inflatable seal for the frictional fixing of the door leaf. The known seal acts in the direction of the door leaf level; it works together with the cross fuse. If the pressure supply for if the seal fails, the cross fuse can come loose and thus pose a danger to travelers.

DE 20 22 487 A describes a door system, wherein a In the closed position, the door leaf is flush with the body wall completes. At one end of the pivoting sliding door points the same a safety gear from one in the door leaf provided recess and a fixed lever. This safety gear may be necessary to avoid vibrations avoid the edge of the door while driving. Another way of functioning this safety device is not described.

AT 387 616 B becomes a swivel sliding door of a vehicle known, the door leaf via a locking device can be locked in the closed position. In addition, the door leaf points at one end a hook that is in the closed position cooperates with a role of the door frame.

With the only closing device according to the sliding door AT 188 232 B hook-shaped transducers are provided, which with a corresponding locking and unlocking device for the door cooperate.

The invention is based on a prior art, as it is EP 0 312 450 A is given.

The sliding door of a railroad car for Passenger traffic, with a door leaf along guides Is movable, which is arranged parallel to the floor being walked on are that with the top and bottom of the door leaf cooperate and on the railway wagon, especially via a Door frames are attached, which is via a locking device Door leaf lockable in closed position in this position Sealable against the door frame via an inflatable seal is, and the door leaf in its position across the guides can be determined, consists essentially in that the sliding door has two door leaves with straight guides and that the Elements in the form of hooks on the outer side areas of the door leaves and corresponding sensors on the Side areas of the door frame or the railroad car formed are and that the seal towards the door leaves is movable and the hooks of the door leaves in the closed position of the door pressed against the sensor of the frame are. Such sliding doors, both open and Closed position arranged inside the wagon box are used as entrance doors between the individual Wagons. So they have the task in their function as Passage door, to have as little space as possible, the largest possible passage in the open position ensure and in their closed position, u. between when the railway wagon in question for the Passenger traffic is in the start or end position of the train, too can also be locked, e.g. B. on locking bars with one own operating mechanism, which should be removable, a large passage is only guaranteed if the Connect sliding doors to each other immediately in the closed position and not a post that allows free passage disabled, connect. A particularly simple and therefore Reliable position fixing of the door leaves in the case of lower or Overpressure, which on the door leaves, especially the door leaves in the front area, but also when passing by Moves and then in the side area, is given when the Door leaves in their position across the guides by hooks on the sliding door and sensors on the door frame or railway wagon be determined in their position across the guides. These measures also cause the door to deform during the pressurization or vacuum, u. between yourself prevented at a test pressure of 6,000 Pa, so that a particularly good sealing of the doors even with these prints can be achieved.

The simpler redundant security systems are, the more the greater the effectiveness of security Activities. Assign the transducers a hook-shaped one Cross section on, so the hooks of the door leaves and the sensors connected to the railway wagon a limitation of freedom of movement across Closing direction in both directions, u. between both at Over and under pressure outside the wagon guarantee.

Are the hooks and / or pickups with the door frame or Door leaf rigidly connected, so there is an engagement of the hook and sensors only by moving the door leaves accessible, with no additional actuation mechanism not intended for the hooks or for the transducers must become.

Are the hooks and / or pickups rigid, particularly in one piece, designed, is another possibility the malfunction excluded.

Instruct the transducers to a stop for the hooks Towards the top, there is an additional one Fixation of the door leaf in the closed position, such as they, for example, when the Railway wagons can be of particular importance.

Assign the hooks and / or pickups at least one surface on, each an acute angle with the Include the direction of movement of the door leaves, whereby especially the vertex points to the closed position, this makes positioning particularly precise the door leaves reached in the closed position, whereby also the different dynamic loads of the Carriage body and thus slight deformations of the same or the door frame is taken into account and one Fixing the door leaves in relation to the locking device is particularly easy to reach, so that a firm fixed door can be obtained, making a Noise nuisance even with high and fluctuating Differential pressure stresses do not exist.

Are the hooks of the door leaves through the inflatable Seal can be pressed against a stop on the transducer, this stop, for example by the Direction of movement, arranged at an acute angle Surface can be so is next to the waterproofing additionally a safeguard against an unwanted opening given the door, which is present even if the Locking mechanism, such as the locking bars, were not operated. Furthermore, it is a particularly safe one The door leaves are fixed in position.

Are the hooks on the end faces or Longitudinal surfaces of the door leaves attached, so is a particularly small space requirement across the direction of movement given the door so that the passage for people in parallel to the direction of movement of the door can be kept particularly large, but none protruding parts leading to disabilities or even to Accidents can cause, are prevented.

Are the transducers with at least one on both sides side, top and bottom closed opening, which points to the hook in the open position of the door, so thereby a particularly secure position fixation of the Door leaves reached in the closed position, because then one predestined freedom of movement, which is only possible through the required play between hook and transducer defined is predetermined. Such sensors are preferred the long sides of the Door frame or the cooperating organs to the corresponding sides of the door leaves arranged.

Are the transducers by a pin or pens, Partial rail or rail formed, so is in particular the front of the doors that are parallel to the committed Floor is provided at the top of the door, one given particularly good additional security of the door, the free mobility by arrangement of the rails parallel to the direction of movement of the door leaves without additional swivel or actuation mechanism is guaranteed.

In the following the invention with reference to the drawings explained later.

The sliding door 1 shown in Fig. 1 is over a Door frame 2 with a front wall, not shown Railway wagons either detachable, e.g. B. via screws, or unsolvable by welding or gluing with the remaining wagon connected. The door leaves 3 and 4 are via carriage 5 along a guide 6 from one Closed position, as shown in the picture, in a Moveable open position. The guide 6 is parallel to committed floor arranged. In the not shown floor is a slit-shaped recess 7 provided in which an extension 8 of the door leaves is feasible. The aligned door leaves also point Window 9 and can be provided with a handle 10 his. The door leaves close via seals 11, 12 to each other and give the entire cross-section when opening free. Both door leaves are via locking bars 13, 14 and an actuating mechanism, not shown, the manual control is removable in the Lockable closed position. The hook 15 and the associated shots 16, the vertical Outside parts of the door leaves 3, 4 or on the door frame 2 are arranged by a rubber profile 17th covered. There are hooks 18 in the upper area of the door leaves and receptacles 19 provided, the hooks over the Carriage 5, which can be moved back and forth in the guides are connected to the door leaves. Furthermore is a seal 20 is provided which is inflatable, wherein at Closed position of the door leaves a fixation on the Closing rods 13, 14, and at the same time by one Inflating the seal 20 provides additional resistance against moving the door leaves is reached and a seal between door leaves and door frame is accomplished.

Such sliding doors serve as passage doors between two wagons, the closing bars and the inflatable seal can only be operated when a Passage through the doors should be prevented like that usually in the front forehead area of the first used wagons and in the back of the forehead last used wagons of a train is required.

The portion of a door leaf 3 shown in FIG. 2 with a door frame 2 is a sectional view along the lines II - II. The door leaf releasably supports a Allen screw 21 connected to a hook 15. The Recording 16 is also detachable via a Allen screw 22 connected to the door frame 2. The Door frame 2 also has a groove-shaped recess 23 in which the inflatable seal 20 is arranged is. If the door leaf 3 is opened, that is, to the drawing moves the lower edge of the drawing, the hook 15 comes disengaged from the recording. The recording has one on both sides as well as up and down limited opening 24 so that the hook at The door is closed by a stop in the movement up, down as well as to the left and is limited to the right. Both the recording 16 and the hook 15 are integrally formed and rigid connected to the door leaf or door frame. The recording 16 and the hook 15 have a surface 25 and 26, respectively with the direction of movement a an acute angle α lock in. The surfaces 25 and 26 are mutually parallel. Now the seal 20 inside with pressurized with a pressure medium, so this presses against the Door leaf 3, whereby the surfaces 25 and 26 to each other Plant come.
