Pivoting sliding door

The invention relates to a pivoting sliding door of the type used primarily, but not exclusively, in railroad cars and buses. When the pivoting sliding door is operated, the existing door leaves move out of a closed position in which they

09881/0399

are usually flush with the outside of the vehicle, inwards or outwards in front of the vehicle wall and can then be moved parallel to this, with the entrance release. The door leaf or leaves remain essentially parallel to the side of the car during the entire movement, so that the door can still be operated when there is little space outside the vehicle.

Known constructions of movement mechanisms for such pivoting sliding doors are bulky, hinder the Passes through the door opening and does not necessarily move the door leaf completely out of the door opening out. In addition, there are difficulties with adequate support of the door leaves during their Pan and slide movements "

The object of the invention is to create a pivoting sliding door that is compact in its movement mechanism, leaves the door opening essentially free and has adequate support for the door leaves.

According to the invention, this object is achieved by that the pivoting sliding door determines the course of the pivoting sliding movement of the door leaf or the door leaf Has guide rail and at least one carrier, which is slidably engaged with the door leaf or leaves in support of the same and together with him or her is movable during his or her laterally inwardly and outwardly pivoting movement.

4093 ;: 1/0399

According to a preferred embodiment, the carrier limited pivot about a substantially vertical axis when the door or leaves are inwardly or outwardly move.

According to a particularly advantageous embodiment, a horizontal TrScrer is provided for a door leaf or for two door leaves opening on two sides, which is supported by at least two pivot arms which can be pivoted about vertical axes so that they result in a parallelogram connection. Furthermore, there are provided a stationary guide rail for guiding the door leaf or the door leaf during their pivoting and sliding movement and at least one support element which is fixedly attached to the carrier and is in sliding engagement with the associated door leaf and is arranged in such a way that it is with the associated door leaf during its entire sliding or longitudinal movement supporting remains in engagement and finally an actuating device mounted on the carrier. Such a pivoting sliding door works as follows. : To open the door leaf or the door leaves, the actuating device exerts a force pointing in the longitudinal direction. The Füh runers rail or guide rails cause the door or leaves to move sideways inwards or outwards and then in the longitudinal direction. During the initial inward or outward movement, said pivot arms and the support also pivot inward or outward, always remaining in engagement with the door leaf or leaves. Thereafter, each door leaf moves in the longitudinal direction, being supported by the support element or the support elements that are on the

1 to 4 show a movement mechanism attached to a railroad car with a side wall 32 for a pivoting sliding door with two door leaves 10, 11 that open and close at the same time. As a rule, a door opening in the side wall is flush with the door leaves 10, 11. For the sake of simplicity, the edges of the door leaves which meet when the door is closed are referred to as front edges 41 and the edges which lie at the edges of the door opening when the door is closed are referred to as rear edges 42. These edges of the door leaf are provided with sealing strips of Guirmi, wherein the sealing strips are made 43 to the leading edge, as is common hollow to avoid at accidentally between wings trapped passengers or objects injury or damage, and further comprise sensor elements that automatically open the door if a person or object is trapped between the leaves. The position of the door leaves when the door is open is shown by broken lines, it being possible to see that each door leaf runs parallel to the outer wall at a certain distance therefrom and practically releases the entire door opening. To get into the open position, each door leaf first moves outward in an arc until it sits in front of the side wall of the car, but remains parallel to the wall of the car, and then moves longitudinally parallel to the wall of the car. When the door is closed, the same movement only takes place in the opposite direction.

For guiding the door leaves when opening and closing the Door are upper guide rails 12, 13 for guiding a wing above the door opening in the car on the underside a support plate 14 attached. Each door leaf has

409881/0399 -

on its inside at the upper end of the front edge an upwardly facing arm 6 or 7, which at its upper End carries a roller 8 or 9 on a vertical pin. The roller 8 or 9 fits into the associated guide rail 12 and 13, as can be seen in FIGS. 2 and 3. Each of the two running rails has a curved one at its inner end. Section 44 in the area of the middle of the door opening and also a long straight main section 45, which runs parallel to the side wall of the wax, so you practice a force on a door leaf in the longitudinal direction of the car, so it forcibly carries out the above-described movement between its open and closed position.

As a support for the door leaves and a pneumatic cylinder 31 for actuating the same, a T-support is parallel to the Car side wall arranged inside the car above the door opening. This T-beam is supported by four swivel arms 2 carried, which form a parallelogram connection. Each swivel arm is over a vertical pivot pin 36 attached to the support plate 14 and connected to the T-beam via a second vertical pivot pin 37. Consequently the T-beam 1 can move inwards and outwards with respect to the door opening during a pivoting movement of the arms, wherein it remains parallel to the side wall of the car.

A support arm 15 or 16 is attached to the T-beam for each door leaf, both of which are just within the boundary the door opening are arranged, in other words near the rear edges of the door leaves when they are in the closed position. Any of these support arms is at its outwardly facing end with a roller 17

409 8 81/0399

or «18 provided around a horizontal and thus to the Car side wall vertical axis 46 is rotatable and in a horizontal running rail 19 and 20, which is on the associated door leaf in the area of the horizontal upper edge of the door leaf is provided parallel to it, sliding to be led. As already explained above, the '"' Door leaf, in order to get from the closed to the open Stelluno, forcibly perform a movement, which first runs along an arch, with the wings coming out sideways * and then parallel to the side wall of the car runs. The rails 19, 20 are shaped so that the rollers 17, 18 both laterally and vertically with them are engaged. Consequently, when the door leaves move outwards, the support arms 15, 16 and thus the T-beam also outwards, this movement being made possible by pivoting the pivot arms 2. During the movement the door leaves slide in the longitudinal direction of the carriage 19, 20 About their associated roles 17 and 18, respectively, where move their points of attack on the door leaves from the rear edges to the front edges of the door leaves. The weight of the The door leaf is therefore held at all times by the T-beam. The above reverses when the door closes Sequence of events, with the T-beam initially remaining in its outwardly pivoted position while the door leaves move towards each other in the longitudinal direction of the car, and then pivot back to its starting position while the Move the door leaf laterally or transversely to the longitudinal direction of the car into the door opening.

Each door leaf is also attached to the T-beam 1 via a slide 4 or 5 attached to the arm 6 or 7 pointing upwards

4Ü388 1/0399

supported and connected to these. Each slide is provided with balls 33 that are laterally and vertically located in upper and lower, in the slider and in a ball guide rail 3 attached to the T-beam Engage grooves. The arms 6 and 7 are attached to the door leaves in the area of their front edges, so that in closed Position of each door leaf on its front edge 41 through the arm 6 or 7 and on its rear edge 42 through the support arm 15 or 16 is supported.

In the open position, however, the door leaves are only supported at the top at their front edge, so that there is a risk that they will sag in the area of their rear edge. To avoid this, support rails 48 are provided at the bottom of the door opening, as shown in FIG. To support the guidance of the door leaf, the support rail shown in FIG. 4 has a lower running rail 24 of the same shape as the associated guide rail 12 (or 13), in which an upward-facing roller 22 engages, which is mounted on a vertical bearing pin 49 is, which sits on a bottom attached to the inside of the door leaf Arn ¹ 21. The arm 21 also carries a support roller 23 on a horizontal bearing journal 50 which rests on a horizontal support rail 25 at least during part of the movement of the door leaf. Preferably, the support rail 25 is arranged so that the support roller 23 engages it as soon as the door leaf has finished its initial outward movement when opening, and the roller is supported on it during the entire longitudinal movement of the door leaf both during opening and when closing.

409 8 81/0399

Such a support rail 48 is provided at least for the rear end of each door leaf; preferably is a support rail 48 and associated lower track 24 for each edge of each door leaf provided, i.e. a total of four support rails.

The doors are operated by the pneumatic cylinder 31, which is attached to the top of the T-beam and its piston rod 34 is coupled to a clamping piece 29 which is integral with the arm 6 or attached to it. This Clamp is attached to the inner barrel of an endless, preferably toothed, belt 26, which over pulleys 27, 28 rotatable about vertical axes and located at the ends of the T-beam runs. The one on the outside The run of the belt 26 is attached to a second clamping piece 30, which is integral with the arm 7 or on this is attached. If the piston rod 34 extends, the belt is moved and the door leaves open. To the When the door is closed, the piston rod is pulled back into the cylinder. In both cases, move in the process the door leaves at the same time and in opposite directions.

Another possible solution is to provide a separate actuating device for each of the door leaves. The door mechanism can also be used for a single door leaf. In this case only that left or right half of the arrangement shown in FIGS. 1 and 2 for use, and the actuating device can be attached directly to the door leaf or an arm attached to it, without the need for an endless belt.

If the shape of the guide rail has been changed accordingly (12 or 13) und'der lower running rail (24) can be The device according to the invention can also be used for doors opening inwards.

Of course, other actuation devices can also be used, for example an electric motor with a pulley driving gear for a single or double leaf door, or a lead screw arrangement.

Fig. 5 shows a further embodiment in which each swivel arm 2, instead of being rotatably mounted directly on a fixed support arrangement, on a further arm 2A is rotatably mounted with the aid of a vertical bearing pin 36. The trunnions 36 are via a connecting part 38 connected to one another and form a parallelogram connection with the swivel arms 2 and the T-beam 1. Each pivot arm 2A is on a support 39 on which the swivel arm 2A is rotatably mounted on a vertical bearing pin 40 on a fixed support structure, For example, a support plate as in Fig. 3 or the car wall attached. In this way, the swivel arms form 2A and the connecting piece 38 a second parallelogram connection. The arms 2 are preferably the same length as the arms 2A. With this arrangement, the T-beam continue to move to the side together with the door leaf or leaves, but its Beweaung is in the longitudinal direction eliminated, and it remains parallel to the side wall of the car.

The mechanism described has a number of advantages. The door opening in the side of the car only needs a little
