[0001] 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.
[0002] 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.
[0003] In the context of this application and the description of the invention below, 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. In
a preferred embodiment, 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 Mittelpufferkupplung).
[0004] In countries, where trains run the risk of coming into contact with snow or ice,
the risk exists that snow or ice accumulates on a surface of the coupler-head. The
same might hold for sand and dust. 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. Further, the retractable covers have a certain amount of
complexity and high weight.
[0005] Given this background, 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.
[0006] This object is solved by the device according to claim 1, the device according to
claim 2, the device according to claim 4, the coupler-head according to claim 14,
the car of a multi-car vehicle according to claim 15, and the multi-car vehicle according
to claim 16. Preferred embodiments are described in the subordinate claims and in
the description following here below.
[0007] 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. With regard to the rotation the same holds and 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. Further, 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.
[0008] Putting this basic concept of the invention into practice, 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.
[0009] In order to obtain the advantages of the invention it is already sufficient, if 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.
[0010] The term "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.
[0011] The term "front window" encompasses a rack or frame-like element having at least
a base, which can be positioned on top of the coupler-head in the mounted state, and
two legs, each leg on a side of the coupler head, the legs can extend from the base.
[0012] 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. The coupler-head
may comprise mechanical, or mechanical and electrical coupling elements. The number
of mechanical or electrical coupling elements can vary as well as the specific arrangement.
An electrical coupling or at least two electrical elements can be positioned on top,
at the bottom and/or the sides of a mechanical or at least two mechanical elements.
The front window can have a width (substantially the distance or maximum distance
between the two legs) in the range of 500 mm to 800 mm, preferably 550 mm to 750 mm,
most preferably 550 mm to 650 mm. In a preferred embodiment the width of the front
window can be 600 mm. The front window can have a height (substantially the distance
or maximum distance between the base on the top and a further base at the bottom)
in the range of 500 mm to 800 mm, preferably 550 mm to 750 mm, most preferably 550
mm to 650 mm. In a preferred embodiment the width of the front window can be 630 mm.
[0013] Preferably, the front window can be positioned in the vicinity of a free end of the
device to provide stability for the device. The cover sections can extend from the
front window in the direction opposite to the contact surface for the front face cover.
The front window can envelope the cover-head in the area of the end of the coupler-head
without taking any specific geometry of the coupler-head into account.
[0014] Such a front window can be a gate- or frame-like element extending substantially
in a plane. The front window can have the shape of a polygon, especially in the shape
of a hexagon seen in the direction of the longitudinal axis of the device. The longitudinal
direction of the device can be parallel to the direction to which the side cover sections
extend from the front window. The front window may be made of metal, especially steel.
Preferably, a material for the front window can be used which is light of weight.
The front window can, therefore, comprise or consist of aluminum or a plastics material,
which might be fiber-reinforced. The front window may have a polygonal shape surrounding
the coupler-head so that the coupler-head is circumferentially enclosed by the frame
allowing movement of the coupler-head, however, also keeping the area of the front
window small. Any shape suitable to circumferentially surround the coupler-head can
be used. The shape of the front window does not require a 1-to-1 reforming of the
outer circumference of the coupler-head, instead a shape enveloping the outer circumference
of the coupler-head using straight or curved lines is sufficient. Simple polygonal
shapes are preferred, such as a rectangular, triangular, hexagonal, heptagonal or
octagonal shape. Such shapes are easy to handle and to construct. A rectangular shape
is possible. In an embodiment, the front window may have a shape which is constructed
from a rectangular section and a trapezoidal section which can be arranged such that
the rectangular section enframes substantially the mechanical coupling elements of
the coupler-head and the trapezoidal section enframes substantially the electrical
coupling elements of the coupler-head. The trapezoidal section can be positioned above
the rectangular section such that the width of the front window tapers with height.
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.
[0015] It is preferred that 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. With this
regard 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.
Two legs or leg sections can extend at an angle in the range of 80° to 130°, preferred
in the range of 105° to 125°, to both sides of the base. These two leg sections which
can be directly connected to the base can form together with the base three sides
of the trapezoidal section. Further, each of the legs can comprise a further section
spaced apart from the base which substantially extends at an angle of 90° to the base,
i.e. substantially vertical in case the device is mounted on the coupler-head. Preferably,
the two legs are arranged substantially symmetrically to the base. Further elements
for stabilizing the front window can be provided in the plane of the front window.
[0016] The front window may comprise attachment elements for the top cover section, side
cover sections and/or bottom cover sections. To cover the coupler head, the front
window can be directly or indirectly connected to a top and two side cover sections
as well as a bottom cover section. The term "section" encompasses the fact that the
top cover section, the side cover sections as well as the bottom cover section can
be made as a single cover comprising the afore-mentioned sections. It is also possible
that the sections are formed as separate sections, which can be connected to each
other, or it can be also possible that at least two sections form a separate piece,
which can be connected to the other sections.
[0017] The term "top cover section" encompasses a sheet-like section of material which can
be a barrier for snow. The term "top" encompasses a geometric position which is positioned
between the two side covers. The two side cover sections can extend from the two legs
of the front window. The top cover section can extend from the base of the front window.
The term "side cover section" encompasses a sheet-like section of material which is
or can be connected to the top cover section. The device comprises at least two side
cover sections.
[0018] The term "bottom cover section" encompasses a sheet-like section of material which
is or can be connected to the side cover sections.
[0019] The cover sections (top cover section, the side cover section as well as a bottom
cover section) 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.
[0020] The term "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.
[0021] 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°.
[0022] The invention further provides a device which is adapted to at least partially cover
a coupler-head of a multi-car vehicle. The device comprises a front window and a top
cover section as well as side cover sections, which are connected to the front window.
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. With this regard,
the seal allows a sealing with a further element, which can be a second device covering
a second coupler-head which is to be coupled with the coupler-head of the first device
and/or a front face cover. The seal can be a lip-seal. The seal can comprise a material
which is at least partially formed from a substantially flat sheet into a bulge- or
bead-like shape along or near the edge of the front window. The bulge- or bead-like
shape can be compressed when a further element abuts the seal in the direction of
the front window. The seal be a 'P' seal which can be formed from a flat sheet or
a rubber extrusion.
[0023] It has been found that a device having such a seal realizes the advantages of the
invention as well. Further, the embodiment having the seal can be combined with the
afore-mentioned embodiment comprising the front face cover. Therefore, the explanations
with regard to the first embodiment hold as well for the device comprising the front
window being connected to the seal.
[0024] In order to obtain the advantages of the invention it is already sufficient, that
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. The device is easy to handle
by the inevitable sealing when a further element abuts the device from the front.
[0025] The invention further provides a device adapted to at least partially cover a coupler-head
of a multi-car vehicle, wherein the device comprises a front window and a rear window,
wherein a top cover section and side cover sections extend between the front window
and the rear window, wherein the top cover section has an inclination such that the
top cover section declines from the front window to the rear window.
[0026] In another embodiment, it might be possible that the top cover section has an inclination
such that the top cover section declines from the rear window to the front window.
[0027] The bottom cover section might have an inclination as well. The inclination might
be such that the bottom cover section declines from the rear window to the front window
or such that the bottom cover section declines from the front window to the rear window.
[0028] Further, the side cover section might at least partially enclose an angle with the
coupler shaft which can be in the range between 1° and 45°, preferred between 5° and
30° such that the side cover sections are at least not parallel to the coupler shaft.
The side cover section might have a bigger distance to the coupler shaft in the area
of the front window than at the area of the rear window. Alternatively, the side cover
section might have a bigger distance to the coupler shaft in the area of the rear
window than at the area of the front window.
[0029] It has been found that a device having such an inclination of the top cover section
realizes the advantages of the invention as well. Further, the embodiment having the
inclination of the top cover section can be combined with at least one of the afore-mentioned
embodiments comprising the front face cover and the seal. Therefore, the explanations
with regard to the first embodiment having the front face cover and/or with regard
to the second embodiment having the seal hold as well for the device comprising a
top cover section having an inclination.
[0030] In order to obtain the advantages of the invention it is already sufficient, that
an inclination of the top cover section is provided such that at least a portion of
the top cover section declines from the front cover to the rear window. Such an inclination
or slope provides benefit by inhibiting snow accumulation.
[0031] The inclination can be provided by attachment means of the front window and the rear
window in such a way that the attachment means are adapted to be positioned to the
coupler-head and/or coupler shaft (in combination with the height of the front window
and the rear window) so that the top of the front window and the top of the rear window
have different height in the mounted state and the top cover section which is attached
at the top of the front window and the top of the rear window declines at least partially
from the front window to the rear window because of its flexible nature.
[0032] In a preferred embodiment, the inclination of the top cover section can be substantially
continuous. It can be possible that the inclination can vary between the front window
and the rear window. This is at least possible, if the top cover section is not actively
supported by any rigid element between the front window and the rear window, which
is preferred. Thus, the inclination can be smaller at the rear window than at the
front window. Due to the effect of non-support between the rear window and the front
window the inclination near the rear window can be 0° or almost 0°, however, this
region is small.
[0033] In a preferred embodiment, the front window has at least one, preferably more than
one, attachment element adapted to be fixed with the coupler-head and/or the coupler
rod. Suitable attaching or fixing positions on the coupler-head can be identified
for each specific coupler-head so that these attaching or fixing positions are solid
and do not affect function of the coupler-head. The attachment of the front window
can be adapted such that the front window is attached or mounted to the coupler-head
or coupler rod such that the front window lies behind the coupling plane. The front
window can be positioned so that the front window is 5 millimeters to 30 millimeters,
preferably 5 millimeters to 20 millimeters, most preferably 5 millimeters to 15 millimeters,
behind the coupling plane which is the coupling plane of the mechanical couplers.
The position of the front window behind the coupling plane allows top clearance on
coupler droop.
[0034] As stated above, the advantages of the invention can be realized with a front window
which can be mounted on the coupler-head and/or coupler rod. The front window being
connected to the cover sections extending on the top and the sides. Further, in front
of the coupler-head the front face cover is provided which closes the device in this
direction. The stable front window provides aerodynamic stiffness to the device as
well as easy access. Since the front window is sized to encompass mechanical as well
as electrical connections of the coupler-head, no impairment of the function of the
both heads occurs. Further, the front window provides a rigid base for a seal which
projects forward in the direction opposite the extension direction of the cover sections.
[0035] In a preferred embodiment, the front window has a contact surface for the front face
cover which is in a plane. This allows seal deployment.
[0036] In a preferred embodiment, the seal at the front window has a varying thickness,
so that the thickness and/or arrangement of the seal takes into account coupler droop
when uncoupled. The seal can have a bigger thickness/projection in the direction of
the longitudinal axis of the coupler shaft in the area of the base (top) of the front
window than at the opposite end of the legs (at the side spaced apart from the base).
However, in an alternative embodiment, the seal can have a smaller thickness/projection
in the direction of the longitudinal axis of the coupler shaft in the area of the
base (top) of the front window than at the opposite end of the legs (at the side spaced
apart from the base).
[0037] In a preferred embodiment, the top cover section, the side cover sections and/or
the bottom cover sections comprise a flexible material of sheet-like nature. The cover
can be tailored to optimize shape such that it avoids body-end equipment and profiles.
The flexible nature of the material allows any unavoidable light contact at extremes
of coupler movement such that the movement will be fully reversible and not impair
function of the coupler-head and/or the device. Together with a light weight front
window the weight of the device can be optimized. The material used for the cover
sections can be a semi-permanent material, especially in the form of a flexible membrane.
The material used for the cover sections as well as the material for the areas of
the front window which cover the coupler-head can be a flexible polymeric sheeting,
especially a textile material, for example a textile reinforced rubber laminate sheet
or a rubber coated textile or a PVC-coated cloth. Also a rubber sheet could be used.
The material used can be CSM (Chlorosulphonated Polyethylene) and/or PVC and/or polyamide
and/or polyester textiles. The rubber might be fire resistant silicone or a robust
chloroprene. In a most preferred embodiment, silicone-aramid is used.
[0038] As described, the cover sections can be made of a single piece or separate pieces
which can be interconnected to each other by any suitable means, especially by sewing
or glueing cover sections together. It also possible that the cover sections surround
the circumference of the coupler-head as a single piece and that the two ends of this
single piece are connected by snap buttons, toggle buttons, turn buttons and the like
to easily mount the device. Means are preferred which can be manually fastened or
manually unfastened even when wearing gloves.
[0039] In a preferred embodiment, a fixation is provided for fixing the front face cover
in a position that the front face cover is swung to the side cover section. The fixation
can be brought into practice by at least one lanyard, a hook, a snap button, a push
button or the like. A means for the fixation is preferred which can be manually carried
out even when wearing gloves.
[0040] In a preferred embodiment, the front face cover comprises an opening adapted to at
least partially surround a projection of the coupler-head. The projection of the coupler
head can be a projection as part of the mechanical coupling, especially a cone-like
projection. The opening allows for a fastening of the front window a little bit staggered
back from the coupler plane such that the projection of the coupler-head can extend
through the opening of the front face cover. The opening can be surrounded by a sheet-like
material having an extension in the direction opposite the extension of the cover
sections. The material enclosing the opening can be of flexible nature. The material
can be a compress-foldable material. The material for enclosing the opening can preferably
be chosen from the group of silicone-aramid, a flexible polymeric sheeting, a textile
material, for example a textile reinforced rubber laminate sheet or a rubber coated
textile or a PVC-coated cloth, CSM (Chlorosulphonated Polyethylene), PVC, polyamide,
and polyester textile.
[0041] In a preferred embodiment, the device further comprises a rear window and/or a rear
face cover for the rear window. The rear window can be positioned at the end of the
cover sections opposite the front window. The rear window can as well comprise a base
and two legs at each free end of the base. Further, the rear window can comprise a
further base, especially positioned at the bottom of the rear window. Thus, the top,
bottom and side cover sections can extend between the front window and the rear window.
The rear window can provide additional stability to the cover sections. An additional
rear face cover can be provided, which can be integrally formed with the rear window
and/or be an additional/separate piece.
[0042] The rear window can have a rectangular shape which may coincide with the rectangular
section of the front window. The rear window can also have a rectangular shape which
is smaller than the rectangular section of the front window. Further, additionally
or as an alternative the rear window can be staggered in height such that legs or
leg sections of the rear window extend to a lower level than the legs of the front
window. This may be suitable because of hoses and cables which are positioned below
the level of the coupler-head in the region of the rear end of the device in mounted
state. However, the hoses and/or cables may also run above the coupler shaft, this
is not excluded.
[0043] In a preferred embodiment, the front window has an area which is bigger than the
area of the rear window. Therefore, the rear window can be smaller. In a preferred
embodiment, the rear window can have the same dimension as the rectangular section
of the front window. Thus, the rear window can have a rectangular shape which corresponds
to the rectangular section of the front window. The area of the rear window can be
minimized to avoid clashing with other equipment and the car, but, however, big enough
to accommodate cables and/or hoses. Therefore, the enclosure or cover with regard
to the device which can be obtained has an inclination with regard to the top cover
section. The top cover section can have an inclination/slope such that the top cover
section descends from the front window, especially the base of the front window, to
the height of the rear window. Snow falling on the top cover section will fall according
to the inclination/slope of the top cover section away from the coupler-head in the
direction of the car. With regard to the position of the front window and the rear
window it is preferred that the base of the front window is arranged higher in the
mounted state at the coupler-head than the base of the rear window to obtain the respective
inclination/slope of the top cover section. Therefore, rear window and front window
can provide attachment points for coupler-head and/or coupler shaft that the base
of the front window is higher than the base of the rear window in the mounted state
of the device. The inclination or slope can be in the range of 10° to 80°, preferred
20° to 60°, most preferred 30° to 60°, with regard to the longitudinal direction,
which can be substantially parallel to the coupler shaft.
[0044] In a preferred embodiment, the front window and the rear window are connected by
at least a longitudinal element. The longitudinal element can provide further stiffness
and stability for the device.
[0045] A stable enveloping box-like device can be provided which can be light in weight
and flexible with regard to the surrounding in the circumferential direction. A specific
geometry of the coupling elements of the coupler-head does not have to be considered.
Straight lines can be assumed from which the front window can be constructed. The
front window can be part of a frame for the sheet-like material of the top cover section,
the side cover sections and the bottom cover section. With this regard it is possible
that the front window can support the entire cover sections to prevent snow from falling
onto the coupler-head. However, the rear window which might be connected to the front
window by the longitudinal element, can be part of the frame as well. The longitudinal
element might be part an additional part of the frame. In a most preferred embodiment,
the rear face cover and the front window are not directly connected by stiff and/or
rigid elements, especially made of metal, to allow free movement of the flexible cover
sections. Any additional longitudinal element can be possible but would be complex,
costly, add weight and possibly provide interference with other parts/elements. It
can be possible that the front window is connected to the rear window by the cover
sections only. The rear window can simply close off the back around the shaft and
the cables and/or hoses. The flexible cover sections can function as a tent and flex.
[0046] In a preferred embodiment, the rear window and/or the rear face cover comprises a
yoke for a fixation of the rear window or the rear face cover to the coupler rod or
shaft. Thus, a stable rear attachment of the cover sections can be provided. The yoke
or shaft collar provides a stable passage of services through the rear of the device,
providing a possibility to minimize or even exclude damage to the hoses or cables
fed to the coupler-head.
[0047] In a preferred embodiment, the rear window comprises openings for a hose and/or a
cable of multi-car vehicle coupling, which can be adapted to the specific hoses and
cables used. Thus, the rear window provides a stable passage carrying the used hoses
and cables. A positioning of services can be controlled. The rear face cover can,
therefore, be adapted to different kinds of coupler-heads.
[0048] In a preferred embodiment, the top cover section and/or a side cover section is adapted
to allow access to the coupler-head. A flap or flap-like element can be provided in
the top cover section and/or the side cover section, the flap-like element having
an overlap at the edge of the flap. The flap can be selectively closed or opened.
To stay in the closed position snap buttons, push buttons or the like can be provided
in the vicinity of the edge of the flap and/or the overlap.
[0049] The invention further provides a coupler-head of a multi-car vehicle, on which the
device adapted to at least partially cover the coupler-head as described above is
mounted.
[0050] The invention also provides a car of a multi-car vehicle comprising a coupler-head
and a device as described above.
[0051] The invention also provides a multi-car vehicle comprising two vehicles which are
connected to each other by coupler-heads of the two vehicles, each of the two coupler-heads
being at least partially covered by a device as described above, and the two devices
abutting each other as a respective front face.

[0053] Fig. 1 shows a device which is adapted to cover a coupler-head 23 of a car of a multi-car
vehicle, especially a train. The coupler-head 23 is not shown in Fig. 1, but can be
seen in Fig. 3 in a front view as well as in a schematic presentation in Figs. 4 and
7.
[0054] The device comprises a front window 1 at one end of the device (see especially Fig.
5) which is positioned in the mounted state in the region of the free end of the coupler-head
23.
[0055] In Fig. 1, the front window 1 is covered by a front face cover 2. Further, connected
to the front window 1 is a top cover section 3 and two side cover sections 4 as well
as a bottom cover section 5. The top cover section, the two side cover sections 4
and the bottom cover section 5 enclose the coupler-head. The top cover section 3,
the side cover sections 4 and the bottom cover section 5 form a single-piece cover
surrounding the coupler-head in a circumferential direction around the longitudinal
axis of the coupler rod to which the coupler-head 23 is attached.
[0056] The front window 1 is mounted on the coupler-head back to the coupling plane defined
by the mechanical coupling plane 6 shown in Fig. 3. Fig. 3 further schematically shows
an electrical coupling 7 which is arranged on top of the mechanical coupling 6.
[0057] To cover the coupler-head in the front 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. In the closed position
(cf. Fig. 1 and 2) the front face cover 2 can be fixed by snap or toggle buttons 9.
During travel of the car, 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.
[0058] 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.
[0059] 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, and 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.
[0060] 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
β is approximately 110° and angle α 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. Further, 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.
[0061] To connect two cars of a multi-car vehicle together by connecting the coupler-heads
of the respective cars, 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).
[0062] In 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. In the open position
shown in Fig. 4, 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.
[0063] 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. Further, 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.
[0064] 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.
[0065] 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.
[0066] Further, 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. Especially, 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. To fix the flap 21 in the closed position
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.
