Abstract
Description
Technical Field
[0001] This invention relates generally to the field of passenger vehicle construction, particularly to the field of trams and light rail vehicles.
[0002] More specifically, the present invention relates to gangway bellows for interconnected buses, and particularly to the drainage of rainwater that accumulates on the roof and on the gangway bellows of the vehicle. Background Technology
[0003] In mainline vehicles such as commuter cars or light rail vehicles such as subway cars, two adjacent railway cars are mechanically connected by a coupling. Each adjacent railway car has a cantilevered half-bridge, and the cantilevered half-bridges of adjacent railway cars together form a passageway connecting the two adjacent cars, allowing passengers to move from one car to another. A canopy surrounding the cantilevered half-bridge is fixed to each car, so that when the cars are connected, the canopies of cars facing each other press against each other to form a closed canopy. Thus, passengers can walk safely and move from one car to another in a relatively protected environment, even while the cars are in motion. This passageway canopy is shown in patent EP020653B1.
[0004] In articulated streetcars similar to trams, individual carriages or modules are connected by articulated bearings. Compared to previous connection types, this connection can only be separated by removing a few bolts. Therefore, the canopy is monolithic and, for example, secured to each end of a module by bolts.
[0005] Typically, aisle canopies form a canopy-like structure around an opening at the front or rear of a passenger car, through which passengers can move from one car to an adjacent car. The aisle canopy has corrugations composed of staggered, parallel valleys and peaks along the longitudinal axis of the vehicle. This corrugated structure allows the aisle to deform as the vehicle travels through curved sections of track. However, rainwater falling on the aisle canopy and flowing onto it from the roof accumulates in the valleys and flows out uncontrollably. Therefore, pedestrians near the tracks and passengers waiting on the platform become wet or soiled by the flowing water or splashes.
[0006] Roof drainage can be controlled by a water trough system using hoses and pipes extending inside the vehicle cabin. This system requires additional installation space to house equipment for more critical functions or to enhance passenger comfort. When operating outside the vehicle, the water trough system can affect the shape of the vehicle body, negatively impacting its external dimensions and aesthetics. Summary of the Invention
[0007] Therefore, the object of the present invention is to provide a top-down, closed-guided roof drainage device that does not obstruct the usable internal volume or external shape of the vehicle body.
[0008] To this end, according to a first aspect of the invention, a drainage channel for a gangway bellow is provided, the gangway bellow having corrugations forming at least one valley having an upward-facing valley top portion and at least one valley top angle, wherein the drainage channel is adapted to be located within the at least one valley top angle of the at least one valley, and when liquid flows through the drainage channel, the drainage channel is operable to guide the liquid accumulated in the valley top portion downward at least partially.

The channel pleated structure includes at least one drainage channel, such that liquid accumulating in at least one of the valley top portions flows through the at least one drainage channel and is guided at least partially downward along the corresponding pleated structure side.
[0017] Optionally, the at least one drainage channel includes a apex portion located within at least one of the valley apex angles, such that liquid accumulated in the respective valley apex portion flows downward along the respective pleated side through the apex portion.

[0019] Optionally, the at least one drainage channel further includes a bottom corner portion located at the bottom corner of the channel fold and connected to the bottom end of the straight portion of the drainage channel, such that liquid accumulated in the valley top portion flows out from below the channel fold, and wherein, preferably, the upper end and / or lower free end of the drainage channel is funnel-shaped.
[0020] Optionally, a drainage channel is located within each valley of the outer folding shed—from at least the upper portion of the valley's apex, through the valley side extending downwards along the corresponding folding shed side—at least until the bottom corner of the channel folding shed.
[0021] Optionally, a apex portion is located in each valley apex, and several or all of the apex portions of the channel fold are connected to a straight section via a manifold portion; and / or the straight section of the drainage channel is positioned on the outer fold or between the outer and inner folds.

[0029] Figure 6 It shows from Figure 1 The perspective view of the tram passage canopy, viewed from above and from the left, depicts a drainage passage with a manifold according to another embodiment of the invention. Detailed Implementation
[0030] For the reader's convenience, the same or similar elements have the same reference numerals throughout the entire set of figures.
[0031] In the following text, when referring to vertical and horizontal, front and back, or up and down, the interpretation must be made by referring to a vehicle in its normal operating position.
[0032] Figure 1 A tram 1 is shown, comprising front and rear passenger cars 2 and 3, which are connected, for example, to an intermediate passenger car 34 and two intermediate passenger modules 35. When the tram 1 moves in direction V, the rear of the front passenger car 2, the rear of the intermediate passenger car 34 or module 34, or the rear of one of the intermediate passenger modules 35 is connected to the adjacent front of the rear passenger car 3, the intermediate passenger car 34, or the intermediate passenger module 35. As needed, the tram may consist solely of a front passenger car 2 connected directly or via an intermediate passenger module 35 to a rear passenger car, with the passenger cars or modules 2, 3, 34, or 35 connected via a passageway canopy 4, which may be, for example, […]. Figure 1 The diagram shows a single-piece or two-section folding canopy halves (not shown), each half fixed to the rear or front of the passenger car / module. In this case, when the two cars / modules are joined together, the two facing folding canopy halves are again pressed against each other. In the following description, the term "car" is used for simplicity, but the description also applies to the passenger module.
[0033] When buses 2, 3, or 34 are connected together, each aisle canopy 4 forms a fully or partially enclosed volume surrounding the articulated canopy 5 that connects the buses 2, 3, or 34. Therefore, passengers can move from one bus / module to another. Figure 2 As shown, the channel pleats 4 include an outer pleat 6 surrounding the inner pleat 7. More commonly, the channel pleat is a single component, making the inner pleat optional. At least the outer pleat 6 has corrugations 33 composed of a plurality of valleys 8, which are spaced apart from each other by peaks 9. The plurality of valleys 8 are arranged parallel to each other along the direction of movement V.
[0034] When buses 2, 3, or 34 are connected, the passageway canopy 4 surrounds the articulated canopy 5, allowing passengers to move safely and securely through the articulated canopy 5 regardless of the weather outside the tram 1. However, when it rains, rainwater falling on the bus roof 10 and the canopy roof 11 tends to accumulate in the valley 8. In conventional trams, the rainwater accumulated in the valley 8 is discharged uncontrollably from the canopy roof 11, and passengers waiting at the platform (not shown) or on the passing tram tracks (not shown) may become wet or soiled due to flowing or splashing rainwater.
[0035] To control rainwater discharge from the roof 11, at least one drainage channel 12 guides the water flowing out of the roof 11. Preferably, one drainage channel 12 is located in each valley 8 of the outer roof 6. Figure 2 As shown, the valleys 8 of the outer pleated 6 extend around the entirety or at least a significant portion of the outer pleated 6. Each valley 8 has an upward-facing valley top portion 13. Each valley top portion 13 extends towards a valley top angle 14 at its end. Two corrugated pleated sides 15 form the sidewalls of the outer pleated 6 and have valley sides 16. Each valley side 16 is aligned with the corresponding valley top angle 14 at its upper end and with the valley bottom angle 17 at its lower end.
[0036] The drainage channel 12 is shaped like a pipe and can be made of the same material as the pleated 4. This material must withstand movement during vehicle use and meet technical requirements, such as being made of silicone or Hypalon. TM The material can be a fabric made of 6, or any other suitable material. Preferably, like the pleated 6 material, the drainage channel 12 material can be flexible to accommodate the deformation of the pleated 6 when two adjacent carriages (e.g., one of the middle carriage 34 and the middle passenger module 35) are at an angle to each other, such as when the tram 1 is in a curve. The drainage channels 12 are located within their respective valleys 8, and are attached to the valleys by, for example, joining, sewing, or integrally manufacturing with the pleated 6.
[0037] Or, such as Figure 3A and Figure 3B As shown, by connecting each side of the C-shaped portion 36 to a peak 9, the drainage channel 12 can take the form of a partial pipe, which, when installed on the corresponding valley 8, forms a conduit with a closed cross-section. Figure 3A As shown, the C-shaped portion 36 is sewn onto both sides of a valley 8, see suture mark 37. Alternatively, the C-shaped portion 36 can be sewn together as follows: Figure 3B The connection or attachment is shown by bolts 38. Each bolt 38 passes through one side of the valley and the U-shaped end 39 of the corresponding C-shaped portion 36. Screws or rivets can also be used instead of bolts 38 to connect the C-shaped portions 36. Alternatively, when formed by a pipe, the drainage channel 12 or the C-shaped portion 36 can be clamped within the corresponding valley 8.
[0038] Each drainage channel 12 includes a apex portion 18 positioned within a corresponding valley apex 14 of the drainage channel 12. The upper end of the apex portion 18 has an inlet 19 into which water accumulating in the valley apex portion 13 flows so as to be guided downward by the apex portion 18 of the drainage channel 12 surrounding the valley apex 14. Figure 4 As shown, the inlet 19 of the apex portion 18 may be funnel-shaped to facilitate water flow. The lower end of the apex portion 18 may optionally connect to the upper end of the straight portion 20 of the drainage channel 12, which extends along a corresponding valley side 16 on the pleated side 15. It should be understood that the straight portion 20 is generally straight and adopts the shape of the pleated side 15.
[0039] like Figure 5 As shown, the bottom end of the downwardly extending straight portion 20 of the drainage channel 12 is optionally connected to the bottom corner portion 21 located within the corresponding valley bottom corner 17. Therefore, water accumulated on the valley top portion 13 and guided by the inlet 19 can be discharged downwards through the drainage channel 12 in a controlled manner and overflow onto the ground through the outlet 22 located at the valley bottom corner 17 of the outer awning 6 without affecting people standing or walking along the tram 1.
[0040] To facilitate water flow out of the drainage channel 12, the outlet 22 can be funnel-shaped, such as... Figure 4 The entrance 19 is shown in the apex portion 18. As described above and... Figures 2 to 4 In an alternative embodiment of the drainage channel 12 shown, the drainage channel 12 may omit the bottom corner portion 21, or even include only the top corner portion 18, as this would be sufficient to guide the water flow accumulated in the valley top portion 13 downward along the valley side portion 16. Similarly, the straight portion 20 of the drainage channel 12 may extend only along a portion of the valley side portion 16 on the fold side 15 of the outer fold 6 (not shown).
[0041] exist Figure 6 In another embodiment of the drainage channel 12 shown, the bottom ends of all or some of the apex portions 18 located within the valley apex 14 are connected to a manifold 32, which is connected to a single straight section 20 extending downward along the corresponding apex side 15 of the outer apex 6. Alternatively, the straight section 20 may be located between the outer apex 6 and the inner apex 7. Thus, water accumulating on the valley apex portion 13 flows in the inlet 19 of the apex portion 18 and is collected by the manifold 32 to be directed to the straight section 20 and discharged downward to the ground. For each channel apex 4, all the apex portions 18 of the outer apex 6 are connected to a single manifold 32. Alternatively, the curved portions 18 of the outer apex 6 are divided into several groups, with each group of apex portions 18 connected to a manifold that is connected to a straight section extending downward along the corresponding apex side 15 of the outer apex 6, or extending downward between the outer apex 6 and the inner apex 7 (not shown).
[0042] The above description and accompanying drawings illustrate various embodiments of specific aspects of the invention, particularly the structure of the drainage channels and their implementation in the passageway canopy of a tram. These can be configured and implemented in other ways and in different environments, such as railway vehicles, light railway vehicles, underground vehicles, or other urban vehicles, such as articulated buses.
