Definitions

  • the invention relates to a pad suitable to reduce the accumulation of snow on a surface of or in a recess of a coupler-head of a train, when the pad is attached to the coupler-head.
  • the invention also relates to a system to reduce the accumulation of snow on a surface of or in a recess of a coupler-head of a train.
  • the invention also relates to a coupler-head of a train and to a method for reducing the accumulation of snow on a surface of or in a recess of a coupler-head of a train.
  • the invention also relates to a pad suitable to reduce the accumulation of snow on a surface or in a recess of a car of a multi-car vehicle and to a car of 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 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 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 (the cover being called a protective shroud in EP 2 308 738 B1 ) 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.
  • an inflatable cushion for sealing an opening provided in the frontal area of a railway-bound vehicle, whereby the coupling shaft of a central buffer coupling connected to the vehicle extends when the vehicle is in the coupled or coupling-ready state through this opening.
  • the cushion in the inflated states covers the opening, but leaves the surfaces of the coupler-head free as can be seen from Fig. 2 and 3 of EP 2 524 850 B1 and hence is not suitable to reduce the accumulation of snow on a surface of or in a recess of a coupler-head of a train. Indeed, it is to be expected that substantial amounts of snow accumulate in the trough that the cushion leaves behind the coupler-head.
  • the problem to be solved is to suggest means that can reliably reduce the accumulation of snow on a surface of or in a recess of a coupler-head of a train.
  • the invention makes use of the general concept to reduce the accumulation of snow on a surface of or in a recess of a coupler-head of a train by use of an inflatable chamber.
  • an inflatable chamber can be kept deflated at first and hence might lead to the accumulation of snow or ice on an outward facing surface of the inflatable chamber.
  • the change of shape of the inflatable chamber will lead to snow being moved off the outward facing surface or for snow and/or ice having frozen into a solid structure on the outward facing surface being cracked into smaller parts and/or being detached from the outward facing surface.
  • the inflation of the chamber and hence the change of shape of the chamber itself can already create a force that ejects the accumulated snow from the outward facing surface.
  • the invention will, however, also reduce the accumulation of snow on a surface of or in a recess of a coupler-head of a train in simply loosening the accumulated snow and/or ice on the surface as will happen, when the inflatable chamber is inflated due to the change of shape of the inflatable chamber, because such loosening of the snow and/or ice on a coupler-head of a train, which typically vibrates and/or moves as the train is driven, will already provide a way to do away with at least some of the accumulated snow.
  • it is suggested to repeatedly inflate and deflate the inflatable chamber.
  • a pad is suggested that is suitable to reduce the accumulation of snow on a surface of or in a recess of a coupler-head of a train, when the pad is attached to the coupler-head, whereby the pad according to the invention has at least one inflatable chamber.
  • a pad that basically consists of an inflatable chamber plus in an preferred embodiment elements like valves and/or connections for hoses necessary for the inflating and/or deflating of the chamber and/or elements necessary to attached the pad to the coupler-head.
  • Such a pad can for example in the inflated state of the inflatable chamber have the shape of a hose with two closed ends or the shape of a ball-shaped balloon or any other three-dimensional shape.
  • a coupler-head of a train especially a coupler-head of a central buffer coupling for a train can have a multitude of pockets and/or recesses on the top or at the bottom or at the sides of the coupler-head.
  • Coupler-heads of trains are often designed with a specific forward-facing geometry, but can sometimes be designed very liberally on their top, at their bottom or at their sides.
  • the pad basically consists of the inflatable chamber, whereby the inflatable chamber can have a complex three-dimensional shape that depends on the area of the coupler-head of the train that it has to fill in its inflated state in order to reduce the accumulation of snow on this surface or in the respective recess of the coupler-head of the train.
  • the advantageous of the invention can be realized with pads that consist of an inflatable chamber that might even have a complex three-dimensional shape depending on the area of the coupler head of the train that it has to fill in its inflated state.
  • the inflatable chamber in its inflated state has a longitudinal extent, for example can be hose-shaped and has a circular or elliptical or square or triangular cross section in a plane, especially preferred in the majority of planes and especially preferred in all planes perpendicular to the longitudinal extent of the chamber.
  • the inflatable chamber in its inflated state has a linear longitudinal extent, which means that the inflatable chamber in the inflated state extends along a straight line.
  • the inflatable chamber in such an embodiment can, for example have the approximate shape of a cigar or a sausage. If the inflatable chamber is of such a design, the above statement about the geometric shape of the cross section is especially true in relation to a cross-section or cross sections, respectively, in planes perpendicular to the straight line along which the inflatable chamber extends. In more complex geometric shapes, an inflatable chamber that in its inflated state has a longitudinal shape and have the shape of a bend sausage or an S-shaped sausage.
  • the pad has the shape of a parallelogram or a trapezoid or is triangular or of circular shape.
  • the shape of the pad will be adapted to the surface or the recess it is to be attached too.
  • the pad will have a material that is provided in excess to the material necessary to a form the inflatable chamber. This excess material can be used to allow for the room necessary for attachment mechanisms to attach the pad to a coupler-head. The use of excess material can also be advantageous to adapted the geometric shape of the pad to a specific geometry, if on the other hand a geometry of the inflatable chamber is desired, that does not fully match with the desired overall geometrical shape of the pad.
  • inflatable chambers with a generally longitudinal extent especially inflatable chambers that extend along a straight line are preferred because of their deflation and inflation properties. It is expected that such inflatable chambers can be inflated more easily and hence more rapidly than inflatable chambers with complex geometric shapes. For this reason, it might be, that for a pad it is preferred to have an inflatable chamber as part of the pad that generally extends along a longitudinal direction, while the pad is to be adopted to be attached to and to cover a surface of a coupler-head that is of a triangular shape or a different shape. In those circumstances, the use of excess material allows to adapt the pad to a desired geometric shape, even if the inflatable chamber is not of that geometric shape.
  • the pad can be attached to (and connected to) or forms part of a uni-piece cover of a coupler-head.
  • cover coupler-heads with covers made from flexible polymeric sheeting, especially textile material, for example a textile reinforced rubber laminate sheet or a rubber coated textile. Also a rubber sheet could be used.
  • Such a cover can, for example, hang down on the sides of a coupler-head.
  • the pad according to the invention can be used as part of such an overall cover in the way that it is placed at or provided for in those regions of the cover, where the cover is to cover horizontal surfaces or surface angled to the horizontal that are not steep enough for snow or ice to slide off easily.
  • the pad in the deflated state of the inflatable chamber is a slim object, preferably with a thickness of less than 100 mm, preferably with a thickness of less than 50 mm and even more preferred with a thickness of less than 10 mm and even more preferred with a thickness of less than 5 mm.
  • the overall non-inflated section (the section that surrounds the inflatable chamber) can be in the region of 2 to 5 mm in thickness, while the inflatable chamber in the uninflated state could be ⁇ 10mm, rising to > 10mm, possible even 50mm inflated. This can help to reduce the weight of the pad.
  • the necessary thickness of the pad is determined by the amount of material that needs to be provided to give the inflatable chamber the shape that it is to take up in the inflated state.
  • the amount of material is determined by the shape that the pad is to have in the deflated state. If it is acceptable for the pad to sag in the deflated state, for example if the pad is supported by a flat surface of the coupler-head or if for other reasons it is acceptable that the pad in the deflated state of the inflatable chamber sags, the thickness of the pad and the material used can be chosen depending on the forces that will act on the pad, for example the air resistance that will act on the pad as the car moves, that carries the coupler-head that carries the pad.
  • the pad is to be self-supporting and is to have a specific geometric shape in the deflated state of the inflatable chamber, the thickness and the type of material used is to be chosen according to other constrains.
  • This second embodiment might lead to a thicker pad in its deflated state than the first embodiment described, where the pad is allowed to sag.
  • the inflatable chamber has an inflation direction, which is the direction in which the change of size of the inflatable chamber is the largest between the deflated and the inflated state of the inflatable chamber.
  • the cross-section of the pad in at least one plane perpendicular to the inflation direction is a parallelogram or trapezoid or is triangular or is of circular shape.
  • the two major extension directions of the pad are in a plane that is perpendicular to the inflation direction.
  • the inflation direction is in the width direction of the pad.
  • the cross-section of the chamber in at least one plane perpendicular to the inflation direction is a parallelogram or a trapezoid.
  • the inflatable chamber in its inflated state has a longitudinal extend that is larger than its width or its height.
  • the pad has at least two inflatable chambers, preferably three inflatable chambers and even more preferred more than three inflatable chambers and even more preferred four inflatable chambers, and especially preferred more than four inflatable chambers.
  • the inflatable chambers of a pad are arranged next to each other, especially preferred immediately neighboring each other.
  • the general geometric shape (straight shape, arc shape, s-shape, etc.) of all inflatable chambers of the pad is the same, while in a first alternative, the actual size of the inflatable chambers might vary, for example the length of a first straight, inflatable chamber compared to the length of a second, neighboring straight inflatable chamber might be different to adapt for certain overall geometries of the pad, while in a second alternative, all inflatable chambers of the pad are of same general geometry and of the same size.
  • the pad has a frame and an elastic material attached to the frame, whereby the inflatable chamber is provided in the elastic material.
  • Such a design allows for easy manufacture and provides a basically rigid design of the pad.
  • reinforcements may be provided for in the elastic material, which either support the rigidness provided by a frame, if a frame is present, or by themselves already provided for a certain rigidness of the pad.
  • a valve is provided in an opening of the inflatable chamber or in a channel that leads to an opening of the inflatable chamber. Such a valve can be used to control the inflation state of the chamber.
  • the pad has a guide wall or a spoiler that can guide the air flowing over the pad and can improve the aerodynamics of the coupler-head.
  • the pad has a heater, especially preferred an electric wire heater.
  • a heater can assist in the reduction of the accumulation of snow on a surface of or in a recess of a coupler head or in a recess of a train.
  • the pad can have the general structure that it has an outer envelope piece, for example a rubber envelope and an internal piece or internal pieces arranged inside the envelope piece, which internal piece (s) aid in creating the inflatable chamber.
  • This divide between an outer envelope and an internal piece gives design freedom to adapt the respective piece to the purpose it is used for.
  • the envelope piece for example can be adapted in shape to the overall environment that the pad is to be used in.
  • the envelope piece can have the necessary elements for the pad to be attached to a certain part, can for example have holes for hooks to pass through or can have parts of a Velcro connection for the pad to be connected to other parts of an overall coupler-cover.
  • the material of the envelope piece can be chosen in view of the strains that will be applied to the pad.
  • the internal piece on the other hand can be designed in view of the needs of inflation.
  • bags of a first material, for example of a coated textile, for example of a rubber reinforced textile or of a textile reinforced rubber.
  • a first material for example of a coated textile, for example of a rubber reinforced textile or of a textile reinforced rubber.
  • These bags can be connected to each other by tubes.
  • the tubes can for example be short length flat tubes that expand open with air.
  • the assembly of such bags can then be placed in an un-vulcanized rubber envelope and the un-vulcanized rubber envelope can then be vulcanized to create the pad.
  • the two sheets used can be un-vulcanized sheets with separating layers (interleaves) placed in the places where the chambers are to be and where the channels/openings between the chambers are to be. If the sheets are then vulcanized, they will stick together in those places, where no interleaves are present and will not stick together where the interleaves are. If desired, the thus formed arrangement can be used as internal pieces that are then additionally placed in an envelope piece, for example an un-vulcanized rubber envelope that is vulcanized to create the pad.
  • the interleave used can for example be textile sheets, paper or even chalk. The two sheets used could also be PVC-coated cloths.
  • the air inlets can be placed to the ends of the bag to allow air flow through the length.
  • a minimum of two air inlets are used for redundancy and more even inflation.
  • the chambers can terminate in a moulded/formed suitable feature, either an inflated flat area into which the connector is inserted, or a vulcanized tube into which a pipe is inserted.
  • a valve will preferably be arranged remote from the bag.
  • the air flow is governed by relay controlled solenoids.
  • the envelope piece and/or the internal piece can be made from textile reinforced rubber. This will allow the pad to handle the necessary pressures and to make the part more robust (ice, impacts - track ballast etc.). It will also aid manufacture.
  • the rubber might be fire resistant silicone or a robust chloroprene.
  • the system according to the invention which is suitable to reduce the accumulation of snow on a surface or in a recess of a coupler-head of a train has a pad according to the invention and a pump that pumps fluid.
  • Suitable means for example hoses are provided to connect the pump to the inflatable chamber, especially preferred via a valve that can control the inflation state of the inflatable chamber.
  • Such a pump can be of a shape that makes it suitable to attach the pump to the coupler head. The pump would thus be carried on the coupler head in a preferred embodiment.
  • pumps that pump fluid are already provided as part of the car, to which the coupler head is connected.
  • such cars typically have a hydraulic system or a pneumatic system.
  • the pumps already provided can be used to inflate the chamber.
  • the pump can reverse its pumping direction, in order to deflate the inflatable chamber.
  • the fluid is air.
  • a drive circuit that drives the pump is provided as part of the system.
  • the drive circuit drives the pump in a manner to inflate the chamber with a frequency of more than one inflation per hour, especially preferred more than one inflation per 10 minutes, especially preferred one inflation per minute, especially preferred one inflation per second.
  • the pump is reversed in order to deflate the inflatable chamber.
  • the system can have thermally activated relay controlled solenoids and a vacuum generator or equivalent to enable inflation/deflation cycle or inflation. These items can be packed into box affixed to head.
  • the coupler head of a car of a multi-car vehicle according to the invention has a pad according to the invention attached to it.
  • the method for reducing the combination of snow on a surface or in a recess of a coupler-head of a train provides for the inflatable chamber of the pad according to the invention to be inflated.
  • Already inflating the inflatable chamber of a pad can help in reducing the accumulation of snow on a surface or in a recess of a coupler-head.
  • the cycle of inflating and deflating the inflatable chamber is repeated, especially preferred with a frequency of more than one inflation per hour, especially preferred more than one inflation per 10 minutes, especially preferred one inflation per minute, especially preferred one inflation per second.
  • the pump is reversed in order to deflate the inflatable chamber.
  • the inflatable chamber is only inflated once, the advantages of the invention might be realized, if a parked multi-car vehicle is to be uncovered from snow, while it is expected that no further snow will accumulate on the surface of a coupler-head or in a recess of a coupler-head in the following use of the multi-car vehicle thereafter. It is expected, however, that in most circumstances, snow or ice will also accumulate on the surface of or in a recess of a coupler-head of a multi-car vehicle while it travels or is in use.
  • the advantages achieved with the pad according to the invention which reduces the accumulation of snow on a surface or in a recess of a coupler-head of a multi-car vehicle or train can also be obtained when using such a pad on other surfaces or recesses of a car of a multi-car vehicle.

  • Fig. 1 shows a coupler head 1 of a train.
  • the coupler head is understood to be the assembly of parts that is attached to a car of the train and contains those parts that are necessary to make a detachable, mechanically reliable connection with a corresponding coupler-head of a neighboring car.
  • the coupler-head 1 has a front facing plate 3 that contains the typical elements necessary for coupler-heads of the shown central buffer coupling type to be coupled to the appropriate coupler-head of a neighboring car.
