Definitions

  • the invention relates to a device adapted to at least partially cover a coupler-head of a multi-car vehicle, a coupler-head of a multi-car vehicle, a car of a multi-car vehicle and a multi-car vehicle.
  • Trains are often designed to allow the connection between a first car of the train and a second car of the train by way of a coupler-head. This allows the cars to be connected to each other in order to form a train comprising these two cars. This does, however also allow the connection to be disconnected in order to create a train that only has one of the two cars that were previously connected. This allows the train operator to adapt the length of the train and the composition of the train (for example, if the cars are different purpose cars) liberally.
  • a coupler-head is understood to be an assembly of parts that is attached to a car of a multi-car vehicle and that contains those parts that are necessary to make a detachable, mechanically reliable connection with a corresponding coupler-head of a neighboring car of the multi-car vehicle, the connection being suitable to allow the transfer of pulling forces from the one car to the neighboring car necessary to tow the one car behind the neighboring car.
  • Coupler-heads sometimes include accessories to those parts that are necessary to make a detachable, mechanically reliable connection. These accessories can be parts of a pneumatic coupling, parts of hydraulic coupling and/or parts of an electric coupling.
  • the accessories can also be housing parts that are used to house those parts that are necessary to make a detachable, mechanically reliable connection.
  • the accessories can also be moveable covers that in a first position cover certain parts of those parts that are necessary to make a detachable, mechanically reliable connection and in a second position do not cover those parts.
  • the Coupler-head can also have a drive mechanism to move the cover from one position to another.
  • the assembly of parts that forms the coupler-head is arranged at one end of a coupler rod, the other end of the coupler rod being attached to the car.
  • a typical example of a coupler-head is a central buffer coupling (referred to in German as Heidelbergpufferkupplung).
  • Coupler-heads of trains may have surfaces where the accumulation of snow or ice or sand is not troublesome for the operation of the coupler-head. But coupler-heads can also have surfaces where the operability of the coupler-head would be reduced, if snow or ice or sand accumulates on this surface. Coupler-heads are often provided with covers at their front-facing surfaces. These covers are often provided with drive mechanisms that can drive the cover from a covering position into a retracted position that sets free the front-facing surface of the coupler-head.
  • Such covers are for example described in EP 2 308 738 B1 , in which the cover have been called a protective shroud or EP 1 350 703 B1 .
  • Working with such retractable covers has shown the problem that if a surface of the coupler-head close to the position that is taken up by the cover in the retracted position is accumulated with snow or ice, the cover will not be able to fully retract and set free the front-facing surface of the coupler-head. There therefore is the need for means to reduce the accumulation of snow on a surface of or in a recess of a coupler-head of a train.
  • the retractable covers have a certain amount of complexity and high weight.
  • EP 3 231 685 A1 discloses a pad suitable to reduce the accumulation of snow on a surface or in a recess of a coupler-head of a train.
  • the pad is part of a cover which also comprises a front cover that can be positioned in front of a front facing plate that contains the typical elements necessary for coupler-heads to be coupled to an appropriate coupler-head of a neighboring car.
  • the front cover is mounted having a mechanism for moving the front cover from a lower position to a position stored on top. Thus, the front cover can move to a position, where it is stored on top. If snow is present on top of the coupler-head and has been accumulated, this snow might be pushed aside by the front cover being moved up.
  • EP 1 524 165 A1 discloses a cover for a coupler-head of a train.
  • a flexible cover is provided, which can be opened by means of a closing device and pulled back or pushed over the coupling.
  • Zippers, Velcro fasteners, snap fasteners or any other type of mechanical fastener that closes or opens slots are referred to as closing devices.
  • WO 2017/215850 discloses a covering for a coupling-head of a coupling assembly and in particular a coupling head of a center buffer coupling.
  • a support structure is described which can be arranged in a fixed position relative to the coupling arrangement and at least one cover element is detachably connected to the support structure, the cover element being designed in such a way as to completely cover the coupling head at the end face when viewed in the longitudinal direction. In case of a desired coupling with a counter-coupling device, the cover element can be removed.
  • the problem to be solved is to suggest means that can reliably prevent the contact of snow and ice or sand or dust on a surface of or in a recess of a coupler-head of a train, wherein the technical design is simple and easy to handle.
  • the basic concept of the invention is to make use of an at least partially housing of the coupler-head comprising a front face cover which can be selectively attached or detached and/or rotates such that the front face cover can be swung to a side of the cover.
  • the detachment of the front face cover will not be hindered by snow or sand because there's only a very little amount of snow or sand on the edge of the front face cover.
  • the side cover will not be covered with a large amount of snow or sand because a large amount of snow will simply fall of the sides due to sloping surfaces and possible vibrations of the coupler-head.
  • the detached front face cover can be stored in the cab of a multi-car vehicle consuming very little amount of space.
  • the technical design for detaching/attaching the front face cover or the providing of the rotation axis is simple and well-known techniques can be used with this regard.
  • a device is provided that is adapted to at least partially cover a coupler-head of a multi-car vehicle.
  • the device comprises a front window and a front face cover.
  • a top cover section and side cover sections are connected to the front window.
  • the front face cover is adapted to be (a) selectively attached to or detached from the front window and/or the cover sections and/or (b) rotatable such that the front face cover can be swung towards a side cover section.
  • a front window is provided, to which a top cover and/or side cover can be directly or indirectly connected and which can be selectively closed or opened at the front by the front face cover by completely removing the front face cover and/or rotating the front face cover to the side of the device.
  • a front window is provided, to which a top cover and/or side cover can be directly or indirectly connected and which can be selectively closed or opened at the front by the front face cover by completely removing the front face cover and/or rotating the front face cover to the side of the device.
  • Such a device is easy to handle and can be simply designed.
  • the construction making use of the basic concept can be easily put into practice.
  • At least partially cover encompasses the meaning according to the description which functions as a cover or enclosure having sections which extend to at least three sides of the front window. The three sides coincide with the top and the sides of the coupler-head. Small apertures or openings can be provided in the sections, however, it is preferred that the sections provide a complete enclosure to the top and the sides. Further, the term “at least partially cover” encompasses the possibility that the coupler head is substantially completely enclosed and that the device provides a complete enclosure also having a bottom cover section additional to the top cover section and the two side cover sections.

  • the front window can be attached to the coupler head so that the base and the legs do not necessarily have to be connected to each other.
  • the front window does not need to be a single piece, but provides stable sections circumferentially surrounding the coupler-head.
  • Base on top and legs at the side of the coupler-head can each be formed or suggested as a bracket or bracket-like element. However, the base and legs can form a single piece.
  • the front window can establish an opening for the access to the coupler-head in the form of an opening at least surrounded by three sides, i.e. especially the top and the sides. Additional to the base and the legs a further base for the bottom can be provided.
  • the front window of the device can be oriented such that the front window establishes an opening in front of the coupler-head.
  • the front window having dimensions which are adapted to the dimensions of the coupler-head.

Due to the tapering a reduction of area is produced which is aerodynamically favoured, while having enough space for the coupler-head even in case the coupler head moves.
  • the front window has a top which is a substantially horizontally aligned line or curve in case the device is mounted on the coupler-head.
  • this line or curve is the base of the front window which can be assumed to be positioned on top of the front window in case being mounted on the coupler-head.

  • the cover sections can have a length extending from the front window which is in the range of 700 mm to 1000 mm, preferred 750 mm to 950 mm, most preferred 800 mm to 900 mm.
  • the length of the cover sections in a preferred embodiment is 830 mm.
  • front face cover encompasses a surface-like closure for closing the opening provided by the front window.
  • the front face cover can have a wraparound edge adapted to contact the front window or the cover sections at the outer edge.
  • a closure can be provided by the wraparound edge such that the intrusion of snow or ice can be reduced or even excluded.
  • a rotation axis for the rotation of the front face cover can be provided in form of a hinge arranged at the front window connecting front face cover and front window.
  • the hinge can be provided at the leg of the front window, which is in the same plane as the side cover section.
  • the hinge can be positioned especially on the leg section of the front window which encloses an angle with the base of the front window which is in the range of 60° to 120°, preferred 70° to 110°, most preferred substantially 90°.
  • the front window is connected to a seal for providing a sealing to a further element, wherein the seal projects in a direction opposite the cover sections.

  • the seal be a 'P' seal which can be formed from a flat sheet or a rubber extrusion.
  • the seal is provided at the edge of the front window with regard to the base (top cover section) and the legs (side cover sections). Such a sealing allows for a sealing for the incidence of snow from the top and the sides.

  • Fig. 3 further schematically shows an electrical coupling 7 which is arranged on top of the mechanical coupling 6.
  • a front face cover 2 is provided which is in the embodiment shown hinged to the front window 1 by a hinge 8.
  • the front face cover 2 can be rotated towards one of the side cover sections 4.
  • the front face cover 2 In the closed position (cf. Fig. 1 and 2 ) the front face cover 2 can be fixed by snap or toggle buttons 9.
  • the front face cover 2 can be fixed in the position shown in Fig. 1 and 2 . Snow will not fall on the coupler-head since the top section cover 3, the side cover sections 4 and the front face cover 2 cover the coupler-head.
  • the front face cover 2 comprises an opening 10, which is covered by a covering 11 of flexible material.
  • the protrusion of the mechanical coupling 6 shown in Fig. 3 can project through the opening 10 and is still covered by the covering 11.
  • the front face cover 2 as well as the front window 1 envelope substantially two sections arranged one above the other.
  • the lower section is a rectangular section 13, depicted by dashed lines in Fig. 3
  • the upper section is a trapezoidal section 14 also depicted by dashed lines in Fig. 3 . This design gives clearance to any movement of the coupler-head.
  • the front window 1 comprises at the top a base 24, which is substantially horizontally aligned.
  • Two legs 25 are connected to the base 24.
  • Two leg sections 25a of the legs 25 are directly connected to the base 24.
  • the legs sections 25a extend at an angle in the range of 80° to 130°. In the embodiment shown in Fig. 3 the respective angle ⁇ is approximately 110° and angle ⁇ is approximately 20°.
  • the two leg sections 25a which are directly connected to the base 24 form together with the base 24 three sides of a trapezoidal section of the front window.
  • each of the legs 25 comprises a further leg section 25b spaced apart from the base 24 which substantially extends at an angle of 90° to the base 24, i.e. substantially vertical.
  • the two legs 25 are arranged substantially symmetrically to the base 23.
  • the front face cover 2 can be swung towards one of the side cover section 4 as depicted in Fig. 4 or detached from the front window (completely).
  • FIG. 4 the coupler-head of the car is schematically depicted by a plate defining the outer circumference of the coupler-head shown in Fig. 3 .
  • the coupler-head can be connected to a further coupler-head of an additional car.
  • the front fact cover 2 can be fixed in the open position by fixation elements 15 shown in Fig. 6 which comprise a lanyard attached to the side cover section 4 and/or the front face cover 2 and a loop attached to front face cover 2 and/or the side cover section 4.
  • the device further comprises a rear window 16 which is arranged at the rear end of the device.
  • the rear window 16 can substantially have the same shape as the rectangular section of the front window 1 positioned at the front end of the device.
  • the area of the rear window 16 is therefore smaller than the area of the front window 1 positioned at the front end.
  • the rear window 16 can be staggered in height such that the rectangular shape of the rear window 16 has a lower level than the rectangular shape 13 of the front window 1.
  • the top cover section 3 has an inclination from the top of front window 1 to the top of rear window 16. The top cover section 3 descends from the front window 1 to rear window 16.
  • Front window 1 comprises a seal 17 which projects in a direction opposite than the side cover sections 4.
  • the seal 17 extends therefore to the free end of the device.
  • Seal 17 provides for a sealing with the front face cover 2 as well as with a further device in case a coupler-head 23 having a similar device is connected to the coupler-head covered by the afore-mentioned device.
  • the two devices abut each other at their respective free ends and thus at the respective seal 17 which is shown in Fig. 8 .
  • Fig. 9 shows a rear face cover 18 which can be attached to the rear window 16 and/or integrally formed with the rear window 16.
  • the rear face cover 18 comprises a yoke 19 which is adapted to be connected to the coupler shaft. Further, the rear face cover 18 comprises through-holes 20 for supporting or directing hoses and cables to the coupler head.
  • FIG. 10 shown in Fig. 10 is an access port for manual intervention/servicing of the coupler-head.
  • the device is therefore adapted to allow access of the coupler-head even in the mounted state of the device.
  • the top cover section 3 and/or a side cover section 4 is adapted to allow access to the coupler-head.
  • the side cover section 4 comprises a flap 21 of the sheet-like material of the side cover section 4 which at the edge of the flap 21 overlaps with the side cover section 4.
  • the flap 21 can be selectively opened or closed.
  • snap or toggle buttons 22 are provided at the edge of the flap 21 and respective corresponding elements 22 at the region of overlap on the side cover section 4.
