Definitions
- the invention relates to a door arrangement for a vehicle, in particular for a rail vehicle, comprising a door frame section defining a door opening, at least a first door leaf element movable in a translational first closing direction from an open position to a closed position, and a sealing arrangement sealing an elongated first gap.
- the first gap in the closed position of the first door leaf element, is formed between the door frame section and the first door leaf element and extends along the first closing direction.
- the sealing arrangement comprises a first sealing surface located at the first door leaf element and an associated second sealing surface located at the door frame section. The first sealing surface and the second sealing surface, in the closed position of the first door leaf element, extend over at least the entire length of the first gap along the first closing direction and contacting each other to seal the first gap.
- the respective sealing concept depends on the closing kinematics of the door, e.g. on the fact if a sliding door or a sliding plug door is chosen. While sliding doors are of rather simple design and, thus, very reliable, they usually imply slight disadvantages regarding their noise isolation properties. This is due to the fact that sliding doors during opening and closing translationally move in a plane. Since conventional elastic contact seals, such as rubber seals or the like, would not withstand the permanent friction at the upper and lower edges of the door (extending parallel to the closing direction of the door) for acceptable amount of time, these upper and lower edges are sealed mostly just by brushes or some kind of labyrinth seal. Obviously, this concept only provides poor performance in terms of sealing against water and/or noise ingress.
- the invention is based on the technical teaching that it is possible to achieve good sealing properties and fast opening and closing of the door in a simple manner if mating sealing surfaces of the sealing arrangement extending along the closing direction of the sliding door leaf are inclined with respect to the closing direction in a wedge-like manner.
- the first sealing surface and the second sealing surface are at least section-wise inclined with respect to the first closing direction.
- This inclination allows to arrange the mating sealing surfaces on the door frame section and on the door leaf such that they come into contact only in the end phase - even only at the very end - of the translational closing movement of the door leaf.
- This provides the advantage that only a short sliding contact occurs while, at the same time and depending on the inclination, a considerable contact pressure may be achieved leading to a tight and reliable sealing of the closed door that is comparable to the one of sliding plug doors. Due to the adjustably short sliding contact, only few wear is to be expected such that conventional simple elastic sealing materials, such as rubber etc., may be used.
- the first sealing surface is facing in the first closing direction while the second sealing surface is facing in a direction opposite to the first closing direction.
- a first surface normal of the first sealing surface pointing away from the first sealing surface has a component directed in the first closing direction and a second surface normal of the second sealing surface pointing away from the second sealing surface has a component directed opposite to the first closing direction.
- At least one of the sealing surfaces may formed by a component of the door leaf element or the door frame section, i.e. integrated into the door leaf element or the door frame section.
- the sealing arrangement comprises a first sealing device and a second sealing device, the first sealing device being located at the first door leaf element and providing the first sealing surface and the second sealing device being located at the door frame section and providing the second sealing surface.
- the first sealing device comprises at least one substantially wedge-shaped first sealing element providing the first sealing surface and/or the second sealing device comprises at least one substantially wedge-shaped second sealing element providing the second sealing surface.
- the mating parts of the sealing surfaces may have different inclinations with respect to the first closing direction that adapt to each other due to elastic deformation when they are pressed against each other. Furthermore, the inclination of the sealing surfaces may continuously or intermittently vary over the length of the gap to be sealed along the closing direction. Preferably, at least a first part of the first sealing surface and an associated second part of the second sealing surface have substantially the same first inclination with respect to the first closing direction, the first inclination being substantially constant. Thus, good and uniform contact may be achieved.
- the mating sealing surfaces have a substantially constant inclination and extend over the entire length (along the closing direction) of the gap to be sealed along the first closing direction.
- the first part of the first sealing surface and the second part of the second sealing surface, in the closed position of the first door leaf element extend over substantially the entire length of the first gap along the first closing direction.
- the first sealing surface and the second sealing surface are stepped along the first closing direction.
- the contact conditions and the sealing force profile may be adjusted to the particular needs.
- at least a third part of the first sealing surface and an associated fourth part of the second sealing surface have substantially the same second inclination with respect to the first closing direction, the second inclination being substantially constant and different from the first inclination.
- the respective sealing surface may be a simple planar or section-wise planar surface.
- the mating sealing surfaces may be designed to form, in a direction transverse to the closing direction, a toothed or labyrinth-like arrangement with one or more protrusions, such as lips or the like, on one sealing surface engaging mating grooves on the other sealing surface.
- at least one of the first sealing surface and the second sealing surface has an elongated first protrusion extending along the first closing direction and the other one of the first sealing surface and the second sealing surface has an elongated first groove extending along the first closing direction, the first protrusion, in the closed position of the first door leaf element, engaging the first groove.
- the closing kinematics of the door arrangement may be of any suitable design.
- the invention is not restricted to applications where a door is opened and closed in a conventional manner by shifting it along a longitudinal axis of a vehicle.
- the first door leaf element has a height direction extending within a door leaf plane defined by the first door leaf element and the first door leaf element has a normal direction extending substantially perpendicular to the door leaf plane, the first closing direction extending substantially parallel to the door leaf a plane and transverse to the height direction.
- the first sealing surface and the second sealing surface are inclined with respect to the normal direction.
- the contact or sealing force acting between the first sealing surface and the second sealing surface has a component acting along the normal direction.
- the first sealing surface and the second sealing surface are inclined with respect to the height direction.
- the contact or sealing force acting between the first sealing surface and the second sealing surface has a component acting along the height direction.
- This embodiment has the advantage that this component of the contact or sealing force acting along the height direction may be easily compensated by a further force acting on the door leaf element such that this component has not to be taken by the guiding mechanism for the door leaf element.
- this component may act against the gravitational force acting on the door leaf element or against a further contact or sealing force component acting on the door leaf element and resulting from at least one further sealing surface pairing.
- a design with the inclination to the normal direction and the design with the inclination to the height direction may be combined if desired.
- a design may be chosen showing a first sealing surface and a second sealing surface being inclined with respect to the height direction and the normal direction.
- the first gap may be located at any suitable location around the area of the door opening.
- the first gap extends in the area of an upper end of the first door leaf element since, here, the invention develops its beneficial effects to a high extent. This is due to the fact that the implementation of complicated closing kinematics poses considerable problems in this area such that the simple kinematics according to the invention are very advantageous.
- the invention may show combined closing kinematics, e.g. sliding kinematics in the area of the first gap combined with sliding plug kinematics in the area of a remote second gap to be sealed.
- a second gap between the door frame section and the door leaf element is sealed in a similar manner to the first gap via sealing surfaces inclined with respect to the closing direction.
- the sealing arrangement is sealing an elongated second gap, the second gap, in the closed position of the first door leaf element, being formed between the door frame section and the first door leaf element and extending along the first closing direction.
- the sealing arrangement comprises a third sealing surface located at the first door leaf element and an associated fourth sealing surface located at the door frame section.
- the first sealing surface and the second sealing surface, in the closed position of the first door leaf element extend over at least the entire length of the second gap along the first closing direction and contact each other to seal the second gap.

- the third sealing surface is facing in the first closing direction while the fourth sealing surface is facing in a direction opposite to the first closing direction.
- the sealing arrangement comprises at least one substantially wedge-shaped third sealing element providing the third sealing surface and/or the sealing arrangement comprises at least one substantially wedge-shaped fourth sealing element providing the fourth sealing surface.
- At least a fifth part of the third sealing surface and an associated sixth part of the fourth sealing surface have substantially the same third inclination with respect to the first closing direction, the third inclination being substantially constant.
- At least one of the third sealing surface and the fourth sealing surface has an elongated second protrusion extending along the first closing direction and the other one of the third sealing surface and the fourth sealing surface has an elongated second groove extending along the first closing direction, the first protrusion, in the closed position of the first door leaf element, engaging the second groove.
- the third sealing surface and the fourth sealing surface are inclined with respect to the normal direction. Additionally or alternatively, similar to further embodiments of the first sealing surface pairing, the third sealing surface and the fourth sealing surface are inclined with respect to the height direction.
- both the first sealing surface and the third sealing surface are inclined with respect to the height direction
- the first sealing surface and the third sealing surface are facing in the same direction.
- the contact or sealing force components acting in both gaps along the height direction may act against the gravitational force acting on the door leaf element.

Abstract
Description
- The invention relates to a door arrangement for a vehicle, in particular for a rail vehicle, comprising a door frame section defining a door opening, at least a first door leaf element movable in a translational first closing direction from an open position to a closed position, and a sealing arrangement sealing an elongated first gap. The first gap, in the closed position of the first door leaf element, is formed between the door frame section and the first door leaf element and extends along the first closing direction. The sealing arrangement comprises a first sealing surface located at the first door leaf element and an associated second sealing surface located at the door frame section. The first sealing surface and the second sealing surface, in the closed position of the first door leaf element, extend over at least the entire length of the first gap along the first closing direction and contacting each other to seal the first gap.
- For passenger doors of railway vehicles different kinds of sealing concepts have been developed. The respective sealing concept, among others, depends on the closing kinematics of the door, e.g. on the fact if a sliding door or a sliding plug door is chosen. While sliding doors are of rather simple design and, thus, very reliable, they usually imply slight disadvantages regarding their noise isolation properties. This is due to the fact that sliding doors during opening and closing translationally move in a plane. Since conventional elastic contact seals, such as rubber seals or the like, would not withstand the permanent friction at the upper and lower edges of the door (extending parallel to the closing direction of the door) for acceptable amount of time, these upper and lower edges are sealed mostly just by brushes or some kind of labyrinth seal. Obviously, this concept only provides poor performance in terms of sealing against water and/or noise ingress.
- To solve this sealing problem with sliding doors it has been proposed to use inflatable seals that are inflated and, thus, pressed against a mating surface only when the door is in a closed position. Such sealing arrangements are known, for example, from
US 4,150, 509 andAT 400 426 B - Another approach to fulfill ambitious requirements regarding noise isolation has been to use sliding plug doors. These sliding plug doors, at the end of the closing movement, perform an additional movement transverse to the closing direction in order to bring the door into contact with conventional elastic seals.
- While the noise reduction properties of these sliding plug doors, in general, are clearly superior to the ones of conventional sliding doors, due to their more complex kinematics, they are more expensive and slightly less reliable. Furthermore, the more complex closing kinematics require longer closing and opening times. Thus, it becomes increasingly difficult to meet the closing time requirements during rush hours, without risking to trap passengers and thus triggering a time consuming re-opening routine. Thus, in other words, the sliding plug doors face severe problems in meeting the rapid passenger flow requirements during rush hours in public mass transportation systems, such as subways or the like.
- It is thus an object of the present invention to provide a door arrangement that, at least to some extent, overcomes the above disadvantages. It is a further object of the present invention to provide a door arrangement that provides, in a simple manner, good sealing properties while, at the same time, allowing fast opening and closing of the door.
- The above objects are achieved, starting from a door arrangement according to the preamble of claim 1, by the features of the characterizing part of claim 1.
- The invention is based on the technical teaching that it is possible to achieve good sealing properties and fast opening and closing of the door in a simple manner if mating sealing surfaces of the sealing arrangement extending along the closing direction of the sliding door leaf are inclined with respect to the closing direction in a wedge-like manner. Thus, according to the invention, the first sealing surface and the second sealing surface are at least section-wise inclined with respect to the first closing direction.
- This inclination allows to arrange the mating sealing surfaces on the door frame section and on the door leaf such that they come into contact only in the end phase - even only at the very end - of the translational closing movement of the door leaf. This provides the advantage that only a short sliding contact occurs while, at the same time and depending on the inclination, a considerable contact pressure may be achieved leading to a tight and reliable sealing of the closed door that is comparable to the one of sliding plug doors. Due to the adjustably short sliding contact, only few wear is to be expected such that conventional simple elastic sealing materials, such as rubber etc., may be used.
- There is no need for any complex closing kinematics but the tight sealing may be achieved by a simple translational closing movement. These very simple linear kinematics allow for fast opening and closing of the door leaf and, thus, to meet the increasingly demanding requirements with respect to rapid passenger flow.
- Further advantages of the invention lie within the contact situation that may be achieved. On the one hand, there is the well defined contact situation that arises by simply pressing against each other two inclined sealing surfaces. Thus, other than with known sealing concepts, the sealing effect is not resulting from a considerably varying reaction force provoked by bending a part of the sealing profile (e.g. brush hairs or rubber lips). On the other hand, there is the ability to adjust the contact force, i.e. the sealing force, acting between the sealing surfaces. This may be done by adjusting the position and/or the inclination of the sealing surfaces.
- Usually, the first sealing surface is facing in the first closing direction while the second sealing surface is facing in a direction opposite to the first closing direction. Thus, in other words, a first surface normal of the first sealing surface pointing away from the first sealing surface has a component directed in the first closing direction and a second surface normal of the second sealing surface pointing away from the second sealing surface has a component directed opposite to the first closing direction.
- At least one of the sealing surfaces may formed by a component of the door leaf element or the door frame section, i.e. integrated into the door leaf element or the door frame section. However, preferably, the sealing arrangement comprises a first sealing device and a second sealing device, the first sealing device being located at the first door leaf element and providing the first sealing surface and the second sealing device being located at the door frame section and providing the second sealing surface. Thus, all components may be easily manufactured, assembled and adjusted at a later stage.
- The inclination of the sealing surfaces may be provided in any suitable way. In a preferred embodiment of the door arrangement according to the invention having a very simple design, the first sealing device comprises at least one substantially wedge-shaped first sealing element providing the first sealing surface and/or the second sealing device comprises at least one substantially wedge-shaped second sealing element providing the second sealing surface.
- The mating parts of the sealing surfaces may have different inclinations with respect to the first closing direction that adapt to each other due to elastic deformation when they are pressed against each other. Furthermore, the inclination of the sealing surfaces may continuously or intermittently vary over the length of the gap to be sealed along the closing direction. Preferably, at least a first part of the first sealing surface and an associated second part of the second sealing surface have substantially the same first inclination with respect to the first closing direction, the first inclination being substantially constant. Thus, good and uniform contact may be achieved.
- In some embodiments of the door arrangement according to the invention which are preferred due to their simple design, the mating sealing surfaces have a substantially constant inclination and extend over the entire length (along the closing direction) of the gap to be sealed along the first closing direction. Thus, preferably, the first part of the first sealing surface and the second part of the second sealing surface, in the closed position of the first door leaf element, extend over substantially the entire length of the first gap along the first closing direction.
- In further embodiments of the door arrangement according to the invention, the first sealing surface and the second sealing surface are stepped along the first closing direction. Thus, the contact conditions and the sealing force profile may be adjusted to the particular needs. Preferably, at least a third part of the first sealing surface and an associated fourth part of the second sealing surface have substantially the same second inclination with respect to the first closing direction, the second inclination being substantially constant and different from the first inclination.
- The respective sealing surface may be a simple planar or section-wise planar surface. To enhance the sealing properties, the mating sealing surfaces may be designed to form, in a direction transverse to the closing direction, a toothed or labyrinth-like arrangement with one or more protrusions, such as lips or the like, on one sealing surface engaging mating grooves on the other sealing surface. Thus, preferably, at least one of the first sealing surface and the second sealing surface has an elongated first protrusion extending along the first closing direction and the other one of the first sealing surface and the second sealing surface has an elongated first groove extending along the first closing direction, the first protrusion, in the closed position of the first door leaf element, engaging the first groove.
- The closing kinematics of the door arrangement may be of any suitable design. In particular, the invention is not restricted to applications where a door is opened and closed in a conventional manner by shifting it along a longitudinal axis of a vehicle. Preferably, the first door leaf element has a height direction extending within a door leaf plane defined by the first door leaf element and the first door leaf element has a normal direction extending substantially perpendicular to the door leaf plane, the first closing direction extending substantially parallel to the door leaf a plane and transverse to the height direction.
- With preferred embodiments of the door arrangement according to the invention, the first sealing surface and the second sealing surface are inclined with respect to the normal direction. Thus, in other words, the contact or sealing force acting between the first sealing surface and the second sealing surface has a component acting along the normal direction.
- With further preferred embodiments of the door arrangement according to the invention, the first sealing surface and the second sealing surface are inclined with respect to the height direction. Thus, in other words, the contact or sealing force acting between the first sealing surface and the second sealing surface has a component acting along the height direction. This embodiment has the advantage that this component of the contact or sealing force acting along the height direction may be easily compensated by a further force acting on the door leaf element such that this component has not to be taken by the guiding mechanism for the door leaf element. For example, this component may act against the gravitational force acting on the door leaf element or against a further contact or sealing force component acting on the door leaf element and resulting from at least one further sealing surface pairing.
- It will be appreciated that the design with the inclination to the normal direction and the design with the inclination to the height direction may be combined if desired. In other words, among others, a design may be chosen showing a first sealing surface and a second sealing surface being inclined with respect to the height direction and the normal direction.
- The first gap may be located at any suitable location around the area of the door opening. Preferably, the first gap extends in the area of an upper end of the first door leaf element since, here, the invention develops its beneficial effects to a high extent. This is due to the fact that the implementation of complicated closing kinematics poses considerable problems in this area such that the simple kinematics according to the invention are very advantageous.
- It will be appreciated that the invention may show combined closing kinematics, e.g. sliding kinematics in the area of the first gap combined with sliding plug kinematics in the area of a remote second gap to be sealed.
- With preferred embodiments of the door arrangement according to the invention, a second gap between the door frame section and the door leaf element is sealed in a similar manner to the first gap via sealing surfaces inclined with respect to the closing direction. Thus, preferably, the sealing arrangement is sealing an elongated second gap, the second gap, in the closed position of the first door leaf element, being formed between the door frame section and the first door leaf element and extending along the first closing direction. The sealing arrangement comprises a third sealing surface located at the first door leaf element and an associated fourth sealing surface located at the door frame section. The first sealing surface and the second sealing surface, in the closed position of the first door leaf element, extend over at least the entire length of the second gap along the first closing direction and contact each other to seal the second gap. The third sealing surface and the fourth sealing surface, again, are at least section-wise inclined with respect to the first closing direction. Again, usually, the third sealing surface is facing in the first closing direction while the fourth sealing surface is facing in a direction opposite to the first closing direction.
- Preferably, to achieve a simple design, the sealing arrangement comprises at least one substantially wedge-shaped third sealing element providing the third sealing surface and/or the sealing arrangement comprises at least one substantially wedge-shaped fourth sealing element providing the fourth sealing surface.
- Similar to the first sealing surface pairing sealing the first gap, at least a fifth part of the third sealing surface and an associated sixth part of the fourth sealing surface have substantially the same third inclination with respect to the first closing direction, the third inclination being substantially constant.
- Furthermore, similar to certain embodiments of the first sealing surface pairing, that the third sealing surface and the fourth sealing surface are stepped along the first closing direction.
- Furthermore, similar to certain embodiments of the first sealing surface pairing with interlocking sealing surfaces, at least one of the third sealing surface and the fourth sealing surface has an elongated second protrusion extending along the first closing direction and the other one of the third sealing surface and the fourth sealing surface has an elongated second groove extending along the first closing direction, the first protrusion, in the closed position of the first door leaf element, engaging the second groove.
- Similar to certain embodiments of the first sealing surface pairing, the third sealing surface and the fourth sealing surface are inclined with respect to the normal direction. Additionally or alternatively, similar to further embodiments of the first sealing surface pairing, the third sealing surface and the fourth sealing surface are inclined with respect to the height direction.
- With certain preferred embodiments of the invention, where both the first sealing surface and the third sealing surface are inclined with respect to the height direction, the first sealing surface and the third sealing surface are facing in the same direction. Thus, for example the contact or sealing force components acting in both gaps along the height direction may act against the gravitational force acting on the door leaf element. Thus they may be compensated by the gravitational force and do not additionally load the guiding mechanism of the door leaf element. In this case, for example, both, the first sealing surface and the third sealing surface may face upward.
- With certain other preferred embodiments of the invention, where both the first sealing surface and the third sealing surface are inclined with respect to the height direction, the first sealing surface and the third sealing surface are facing in opposite directions, e.g. towards or away from each other. Here, the contact or sealing force components acting in both gaps along the height direction may act against each other and even compensate each other such that they do not additionally load the guiding mechanism of the door leaf element.
- The second gap may be arranged at any suitable location. Preferably, the second gap extends in the area of a lower end of the first door leaf element. With other embodiments, the first and second gap are located on opposite sides of the first door leaf element. Then, for example, said first gap extends in the area of an inner face said first door leaf element and said second gap extends in the area of an outer face of said first door leaf element and in the area of said first gap. With such a double sided arrangement and sealing surfaces inclined to the normal direction, a compensation of the contact or sealing force components acting in both gaps in the normal direction may be achieved.
- It will be appreciated that the invention may of course also be applied to door arrangements with more than one door leaf element. The sealing surfaces of the further door leaf elements may be designed in a similar manner to the ones of the first door leaf element. In particular, two door leaf elements contacting in a contact plane may be provided with sealing surfaces arranged in mirror symmetry with respect to this contact plane.
- Thus, similar to the first door leaf element, preferably, a second door leaf element is provided, the second door leaf element being movable in a translational second closing direction from an open position to a closed position, and the sealing arrangement is sealing an elongated third gap, the third gap, in the closed position of the second door leaf element, being formed between the door frame section and the second door leaf element and extending along the second closing direction.
- Similar to the first door leaf element, preferably, the sealing arrangement comprises a fifth sealing surface located at the second door leaf element and an associated sixth sealing surface located at the door frame section, the fifth sealing surface and the sixth sealing surface, in the closed position of the second door leaf element, extending over at least the entire length of the third gap along the second closing direction and contacting each other to seal the third gap, the fifth sealing surface and the sixth sealing surface being at least section-wise inclined with respect to the second closing direction.
- Furthermore, similar to the first door leaf element, preferably, the sealing arrangement is sealing an elongated fourth gap, the fourth gap, in the closed position of the second door leaf element, being formed between the door frame section and the second door leaf element and extending along the second closing direction.
- Similar to the first door leaf element, preferably, the sealing arrangement comprises a seventh sealing surface located at the second door leaf element and an associated eighth sealing surface located at the door frame section, the seventh sealing surface and the eighth sealing surface, in the closed position of the second door leaf element, extending over at least the entire length of the fourth gap along the second closing direction and contacting each other to seal the fourth gap, the seventh sealing surface and the eighth sealing surface being at least section-wise inclined with respect to the second closing direction.
- The first closing direction may have any suitable relation to the second closing direction. Preferably, the first closing direction is substantially opposite to the second closing direction, since, thus, a very simple configuration is achieved.
- Preferably, at least one of the sealing surfaces is formed on an elastic sealing device. The elasticity may be provided by the material of the sealing surface itself or by other suitable resilient means supporting the respective sealing surface. Thus, it is possible to compensate for misalignments and to allow greater tolerance ranges.
- The invention further relates to a vehicle, in particular a rail vehicle, with a door arrangement according to any one of the preceding claims.

- In the following a first preferred embodiment of a
door arrangement 101 for arail vehicle 102 according to the invention will be described with reference to Figures 1 to 3. Figure 1 shows a schematic representation the door arrangement 1 while Figures 2 and 3 are schematic partially sectional views of the door arrangement of Figure 1 along line II-II of Figure 1 in a closed and opened position. - The
door arrangement 101 is a sliding door arrangement and comprises a firstdoor leaf element 103 and a seconddoor leaf element 104 that are moveable along a translationalfirst closing direction 105 and a translationalsecond closing direction 106, respectively, from the opened position shown in Figure 3 to the closed position shown in Figure 2. - The first
door leaf element 103 and the seconddoor leaf element 104 close an opening 102.3 defined by a door frame section 102.2 of a car body 102.1 of thevehicle 102. However, it will be appreciated that the door frame section, with other embodiments of the invention, may also be formed by a separate door frame mounted to the car body. - The first
door leaf element 103 has a height direction 103.1 extending within a first door leaf plane defined by the firstdoor leaf element 103 and a normal (or transverse) direction 103.2 extending substantially perpendicular to the door leaf plane. Thefirst closing direction 105 extends substantially parallel to the door leaf plane and transverse to the height direction 103.1. - A sealing
arrangement 107 is provided sealing, among others, afirst gap 108 located at an upper edge on an inner face of the firstdoor leaf element 103 between the firstdoor leaf element 103 and the door frame section 102.2. To this end, the sealingarrangement 107 comprises afirst sealing device 109 mounted to the firstdoor leaf element 103 and a correspondingsecond sealing device 110 mounted to the door frame section 102.2. - The
first sealing device 109 is a wedge shaped elastic rubber element having a first sealing surface 109.1 that extends over the entire length of thefirst gap 108 along thefirst closing direction 105. The first sealing surface 109.1 is a planar surface that has a constant first inclination with respect to thefirst closing direction 105 and with respect to the transverse direction 103.2 of the firstdoor leaf element 103. - The
second sealing device 110 is a wedge shaped elastic rubber element having a second sealing surface 110.1 that extends over the entire length of thefirst gap 108 along thefirst closing direction 105. The second sealing surface 109.1 is a planar surface that also has the constant first inclination with respect to thefirst closing direction 105 and with respect to the transverse direction 103.2 of the firstdoor leaf element 103. - The first sealing surface 109.1 is facing in the
first closing direction 105 while the second sealing surface is facing in a direction opposite to thefirst closing direction 105. Thus, a first surface normal of the first sealing surface 109.1 pointing away from the first sealing surface 109.1 has a component directed in thefirst closing direction 105 and a second surface normal of the second sealing surface 110.1 pointing away from the second sealing surface 110.1 has a component directed opposite to thefirst closing direction 105. - It will be appreciated that, with other embodiments of the invention, the first and second sealing surface may have different inclinations with respect to the first closing direction. In this case, the inclination difference may be compensated by elastic deformation occurring within at least one of the first and second sealing device.
- As can be seen from Figure 3, in the opened position, the first sealing surface 109.1, in the transverse direction 103.2, is located at a distance from the second sealing surface 109.1. As the first
door leaf element 103 is moved along thefirst closing direction 105, due to the inclination of the first sealing surface 109.1 and the second sealing surface 110.1, these surfaces approach each other and contact each other only at the end part of the closing movement. As can be seen from Figure 2, in the closed position, the first sealing surface 109.1 is then firmly pressed against the second sealing surface 109.1 to seal thefirst gap 108. - The sealing
arrangement 107 further seals asecond gap 111 located at a lower edge of the firstdoor leaf element 103 between the firstdoor leaf element 103 and the door frame section 102.2. To this end, the sealingarrangement 107 comprises a third sealing device 112 mounted to the firstdoor leaf element 103 and a corresponding fourth sealing device 113 mounted to the door frame section 102.2. - The third sealing device 112 and the fourth sealing device 113 are arranged and designed in the same manner as the
first sealing device 109 and the second sealing device 110 (only shifted along the height direction 103.1 towards the lower edge). Thus, it is here referred to the above explanations. Again, the third sealing device 112 is a wedge shaped elastic rubber element having a third sealing surface that extends over the entire length of thesecond gap 111 along thefirst closing direction 105. The third sealing surface is a planar surface that again has the constant first inclination with respect to thefirst closing direction 105 and with respect to the transverse direction 103.2 of the firstdoor leaf element 103. - The fourth sealing device 113 is a wedge shaped elastic rubber element having a fourth sealing surface that extends over the entire length of the
first gap 108 along thefirst closing direction 105. The fourth sealing surface is a planar surface that also has the constant first inclination with respect to thefirst closing direction 105 and with respect to the transverse direction 103.2 of the firstdoor leaf element 103. - However, it will be appreciated that, with other embodiments of the invention, the third and fourth sealing surface may also have a different inclination than the first and second sealing surface.
- In the opened position, the third sealing surface, in the transverse direction 103.2, is located at a distance from the fourth sealing surface. As the first
door leaf element 103 is moved along thefirst closing direction 105, due to the inclination of the first and second sealing surface, these surfaces approach each other and contact each other only at the end part of the closing movement. Thus, in the closed position, the third sealing surface is then firmly pressed against the fourth sealing surface to seal thesecond gap 111. - The second
door leaf element 104 is arranged symmetrically to itscontact plane 114 with the firstdoor leaf element 103. To seal the third and fourth gaps corresponding to the first andsecond gap arrangement 107 comprises corresponding fifth to eighth sealing devices having corresponding mating fifth to eighth sealing surfaces that are identical with the first to fourth sealing surfaces of the first to fourth sealing devices. However, it will be appreciated that, with other embodiments of the invention, the fifth to eighth sealing devices may differ from the first to fourth sealing devices. In particular, the fifth to eighth sealing surfaces may differ from the first to fourth sealing surfaces. - The lateral gap 115.1 is sealed by lateral sealing devices that extend in the height direction 103.1 and continue the respective sealing surfaces of the adjacent first and third sealing devices and the second and fourth sealing device, respectively. Thus, these lateral sealing devices as well have planar sealing surfaces that are inclined with respect to the
first closing direction 105 and with respect to the normal direction 103.2 of the firstdoor leaf element 103. The lateral gap 115.2 at the seconddoor leaf element 104 is sealed by corresponding lateral sealing devices. - To compensate for the components of the sealing or contact forces acting in the normal direction 103.2 on the door leaf elements, further sealing devices in mirror symmetric arrangement with respect to the door leaf element plane may be provided on the outer face of the
door leaf elements contours 116. Thus, the guiding mechanism (not shown) of thedoor leaf elements - Figures 4 to 6 show a further preferred embodiment of a
door arrangement 201 for arail vehicle 202 according to the invention. - The
door arrangement 201, again, is a sliding door arrangement and comprises a firstdoor leaf element 203 and a seconddoor leaf element 204 that are moveable along a translationalfirst closing direction 205 and a translationalsecond closing direction 206, respectively, from the opened position to the closed position shown in Figure 4. - The first
door leaf element 203 and the seconddoor leaf element 204 close an opening 202.3 defined by a door frame section 202.2 of a car body 202.1 of thevehicle 202. However, it will be appreciated that the door frame section, with other embodiments of the invention, may also be formed by a separate door frame mounted to the car body. - The first
door leaf element 203 has a height direction 203.1 extending within a first door leaf plane defined by the firstdoor leaf element 203 and a normal (or transverse) direction 203.2 extending substantially perpendicular to the door leaf plane. Thefirst closing direction 205 extends substantially parallel to the door leaf plane and transverse to the height direction 203.1. - A sealing
arrangement 207 is provided sealing afirst gap 208 located at an upper edge of the firstdoor leaf element 203 between the firstdoor leaf element 203 and the door frame section 202.2. To this end, the sealingarrangement 207 comprises afirst sealing device 209 mounted to the firstdoor leaf element 203 and a correspondingsecond sealing device 210 mounted to the door frame section 202.2. - The
first sealing device 209 is a wedge shaped elastic rubber element having a first sealing surface 209.1 that extends over the entire length of thefirst gap 208 along thefirst closing direction 205. The first sealing surface 209.1 is a planar surface that has a constant first inclination with respect to thefirst closing direction 205 and with respect to the height direction 203.1 of the firstdoor leaf element 203. - The
second sealing device 210 is a wedge shaped elastic rubber element having a second sealing surface 210.1 that extends over the entire length of thefirst gap 208 along thefirst closing direction 205. The second sealing surface 209.1 is a planar surface that also has the constant first inclination with respect to thefirst closing direction 205 and with respect to the height direction 203.1 of the firstdoor leaf element 203. - The first sealing surface 209.1 is facing in the
first closing direction 205 while the second sealing surface is facing in a direction opposite to thefirst closing direction 205. Thus, a first surface normal of the first sealing surface 209.1 pointing away from the first sealing surface 209.1 has a component directed in thefirst closing direction 205 and a second surface normal of the second sealing surface 210.1 pointing away from the second sealing surface 210.1 has a component directed opposite to thefirst closing direction 205. - It will be appreciated that, here as well, with other embodiments of the invention, the first and second sealing surface may have different inclinations with respect to the first closing direction. In this case, the inclination difference may be compensated by elastic deformation occurring within at least one of the first and second sealing device.
- As can be seen from the dashed
contour 217 of Figure 4 (indicating an opened position of the first and seconddoor leaf element door leaf element 203 is moved along thefirst closing direction 205, due to the inclination of the first and second sealing surface 209.1 and 210.1, these surfaces approach each other and contact only at the end part of the closing movement. As can be seen from Figure 4, in the closed position, the first sealing surface 209.1 is firmly pressed against the second sealing surface 209.1 to seal thefirst gap 208. - The
first sealing device 209 and thesecond sealing device 210 have the same dimension in the normal direction 203.2 but are slightly offset along the normal direction 203.2. Thus, during the sliding movement, there is no friction between thefirst sealing device 209 and the door frame section 102.2 as well as between thesecond sealing device 210 and the firstdoor leaf element 203. - The sealing
arrangement 207 further seals asecond gap 211 located at a lower edge of the firstdoor leaf element 203 between the firstdoor leaf element 203 and the door frame section 202.2. To this end, the sealingarrangement 207 comprises athird sealing device 212 mounted to the firstdoor leaf element 203 and a correspondingfourth sealing device 213 mounted to the door frame section 202.2. - The
third sealing device 212 and thefourth sealing device 213 are designed in the same manner as thefirst sealing device 209 and thesecond sealing device 210. Thethird sealing device 212 and thefourth sealing device 213 are arranged to be mirror symmetric, with respect to a centralhorizontal plane 217, to thefirst sealing device 209 and thesecond sealing device 210. Thus, it is here referred to the above explanations. - Again, the
third sealing device 212 is a wedge shaped elastic rubber element having a third sealing surface 212.1 that extends over the entire length of thesecond gap 211 along thefirst closing direction 205. The third sealing surface 212.1 is a planar surface that again has the constant first inclination with respect to thefirst closing direction 205 and with respect to the height direction 203.1 of the firstdoor leaf element 203. - The
fourth sealing device 213 is a wedge shaped elastic rubber element having a fourth sealing surface 213.1 that extends over the entire length of thefirst gap 208 along thefirst closing direction 205. The fourth sealing surface 213.1 is a planar surface that also has the constant first inclination with respect to thefirst closing direction 205 and with respect to the height direction 203.1 of the firstdoor leaf element 203. - However, it will be appreciated that, with other embodiments of the invention, the third and fourth sealing surface may also have a different inclination than the first and second sealing surface.
- In the opened position, the third sealing surface 212.1, in the normal direction 203.2, is located at a distance from the fourth sealing surface 213.1. As the first
door leaf element 203 is moved along thefirst closing direction 205, due to the inclination of the first and second sealing surface, these surfaces approach each other and contact only at the end part of the closing movement. Thus, in the closed position, the third sealing surface 212.1 is then firmly pressed against the fourth sealing surface 213.1 to seal thesecond gap 211. - The first sealing surface 209.1 and the third sealing surface 212.1 face in opposite directions, here towards each other. This provides for a mutual compensation of the components of the sealing or contact forces acting in the height direction 203.1 on the first
door leaf element 203. Thus, the guiding mechanism (not shown) of thedoor leaf element 203 may be relieved from the reaction forces resulting from these sealing or contact force components. - It will be appreciated that, with other embodiments of the invention, the first sealing surface and the third sealing surface may face in the same direction, e.g. upwards. This provides for a compensation of the components of the sealing or contact forces acting in the height direction on the first door leaf element with the gravitational force acting on the first door leaf element. Thus, the guiding mechanism (not shown) of the door leaf element may be relieved from the reaction forces resulting from these sealing or contact force components.
