D~vice ~or~i~g a pa~3ag~w~y ~et~een t~o coupled ve~icle~
The prasent in~ention concerns a device, totally enclosed
by means of a bellows-like shrouding, permitting pa~sage
0 between twc coupled vehicles, in particular rail vehicles,
s~id device consisting of two basic parts that are ~:~
adju~table in length and Qach o~ ~hich is linked at the one
end with one of the respective vehicles, whereas at l~ast
portions of the free ends of both basic parts ara s-parably
ls linked to e~ch other, with each basic part co~prising
~oldable bridging p~ssageway components, a bellows-like
shr~uding mQanS, as well as if desired a ceiling casing, ::~
and having, ~t the free ends of the shrouding parts,
surroundin~ central frames that are link-d to each o~her
and ~hich are supported, or rather carri~d, eit~er ~xom
abo~e or ~rom below by m-ans of at lea~t two supports
extending betwe~n the vehicles which are adjustable in
length and essentlally operate in a horizontal plane.
Passageway devices bet~-n two coupled, rail-bound vehicles :~:
are known in the most varied forms of embodiment. Equally
known are the manifold probl-ms occurring with such
passageway devices. .
one of the probl~ms is to support th~ device, whether it
does consist of one or two basic parts, in such a way that
a passageway results which is as simpl~ as possibl¢ and
which offers the us~r trouble-free passag~. The passageway
device must either be supported from below or if required ~:
~e suspended from a complex arrangQment. With this typs of -~:
support there have o~ late arisen proble~s because the :; ~

WO 95/06580 2 PCT/CH94/00164
passagQways are relatively short and are used between
vehicles that are also deployed on [railway lines having]
re~atively small curve radii. ~e~e arises the problem that
the pas~ageway's support from below becomes insufficient or
at least unreliable, at least in the important central
portion.
It is the ob~ective of the present invention to create a
passageway devicQ o~ the initially dQfined type which
en~ures a passage that is largely without problems while
0 having simple constructional requirements. This objective
is solved according to the inVQntion with a passageway
device of the initially cited kind by means o~ the features
defined in the characterising part of Claim 1.
The arrangement o~ auxiliary fra~es according to the
invention, and their co-operation with the supports e~ect~
a reliable carriagQ~ eith-r from below or ~rom above, of
the central fra~es, the auxiliary ~rames and thus of the
pa~sageway shrouding parts and above all of the ~oldable
bridging parts. With the supports ~or~ed as scissors and/or
telescopic bearers there even occurs a forced angular
transmission ~of forces] onto these supports that is
indep~ndent of the curvQ radius respectively the angular
position o~ the two coupled vehicles, which in turn ensures
an optim~l support Sor the passageway device proper. I~
this e~fect is desired or r~quired, it can be achi~ved, in
the case of support constructions in th~ form of
telescopes, by m~ans of additional guiding elements, ~or
instancQ in tha ~orm of scissors.
Particular embodiments o~ the passageway device according
to the inv~ntion are defined in Claims 2 to 13. ~he
inventinn is explaiDed in greater detail in the following
with re~erence to the drawi~g. Shown ar~ in

The passageway device according to Fig 1 is to be built in
bet~een twc vehicle parts 1,2 It consists of two basic
tO parts, ~ach end of which is connected with one of the
vehicles 1 rQspectively 2 The fr~ ends of the basic ~arts
are separably linked to each oth-r
Each basic part possesces foldabl~ pasSagQway bridging
parts 3 respectively 4, and furthermore a ceiling casing 5
~5 r~spectively 6 as well as each a bellows-like shrouding
part 7 respectively 8
The shro~ding parts 7,8 each possess a surrounding central
fra~e 9 rQspectively 10 at their free ends, which are
connected to each other by m~ans Or suitable coupling
~eans, for example coupling bars 11 r~sp~ctively 12 In the
centre af each shrouding part 7,8 is proposed a surrounding
auxiliary frame 7', a ~ each which ensures optimal op~ration
of th~ pass~g~way
Each passageway bridging part 3 respectively 4 in turn
~6 consi~ts of two ~arts 3',3" respectively 4',4", of whic~ in
e~ch cas~ one 3' resp~ctively 4' i6 articulated at thQ
associated vehicle 1 respectiv-ly 2, and th~ other is
articulated at the contral ~rame 9 respectively 10 When
the vehicles 1,2 are coupled and the passageway device is
depl~yed, t~ part 3' respectively 4' articulated at the
vehicl~ 1 respectively 2 in this case is supported on ths
associated auxiliary frame 7' respectively 8', while the
second part 3" respectively 4" when folded down is
support~d by the first part 3' respectively 4'

Th- central frames 9,la and the auxiliary frames 7~,8' are
supportQd, ac~ording to the in~ntion, from below by
supports in such a ~ay t~at they are able to carry not only
the weight of ths passageway device hut also m~ximum
operating weights (of persons utilising the passageway)
The t~pe of th~s~ ~upports will be explained in more detail
later
At the vQrtical pillars of the door openings of the
vehicl~s 1 and 2 are articulat~d swivelling ~door] wings
0 13,14 respectively 15,16 which, togather with corresponding
swi~elling wings 13',14' r~spectively 15',16', lie against
t~e shroudings 7,8 respectively the auxiliary frames 7',
8', overlapping the vertical posts o~ the frames 9,10 as
soon aq the deYice is put together These swivelling [door]
wings furthermor~ possess ~lasto~eric parts that lie
against th~ passagoway bridging parts 3, 4 respeceiv~ly the
ceiling casings 5, 6
.
Thus a passageway d~vice is formed in which the passage is
co~pletely encased by the swivelling ~door] wings
respectively the bridging parts and ogiling casing, and the
entire arrangement is su~rounded by a bellows-liXe
shroudlng~
As mentioned earli~r, the central rames 9, 10 and th~
auxiliary frames 7',8' o~ the passageway device are
2S supported by length-adjustable supports, pre~erably by
multi-section scissors 17,18 respectively 19, 20 . The ~ulti~
s~ction 5Ci sors 17,18 and 19,20 act in a horizontal plane ;~
and are each linked to one o~ the vehicl~s by means of a
univ~rsal joint (see Fig 3J and oth~rwise with their free
-nd~ to a directly opposite pair of scissors by m~ans of a
vertical articulation bolt (Fig 4) The vertical - ~;~
articulation bolts at the point of junction and t~e equally ~-
vertical articulation bolts of the scissors prop~r produce, --
if th~ cissors legs are suitably siz~d, a support between
35 the two vehicles 1, 2 that i5 absolutely flexionally stiff ~
in a v~rtical dir~ction Since the scissors are articulated ~ -
at the vehicles themselYes by means o~ horizontal bolts of

the universal joint (Fig 3), differences of level ~etween
the two vehicles during operation can be accommodated
without problems It has b~Qn found that this construction,
which is intrinsically capablQ o~ transmitting all angles
bQtween the vehicles 1,2, forms an optimal support ~or the
passageway device Uncoupling the two v~hicles is
relatively simple, being achie~ed by releasing both the
linkage bolts between the scissors on the one hand, and the
coupling between the central fram~s 9, lo on the other
0 hand Subsequently, each basic part can be pushed back
against the associated vehicle part and ~can b-] fixed
there
As s~own by the drawing, the central frames 9,10 are
articulated at the associated vehicles by means of a
length-adjustable guide 21,22 respectively 23,24 between
the shroudings 7,8 and the ceiling casings 5,6 These
guides are pr~erably also for~ed as scissors, whereby
these scissors centre the auxiliary frames 7',8' and guide
the central Prame 9,lo
Due to this simple construction with central and auxiliary
~rames and the supports 17,18 r-spectivQly 19,20,
preferably ~ormed as scissors, one obtains a faultless
support for the passageway device in practically any
imaginabls angular posi~ion the two vehicle parts may ta~e
- 25 vis-a-vis ach other The passage supported in this way i5
impeccably enclosed on all sides and thus protected against
all outside influences (draughts, noise)
As mention-d earlier, Fig 2 shows the sch~m~tic ~ormation
and the ~Sect of the supporting scissors in the horizontal
~ plane~ The scissor legs ~5,26 cross at ~oint 27 and are
~ormed as continuous, rigid bearers The legs 28,29
respectively 30,31 are articulated at the legs 25,26 ~y
means o~ vertical joint bolts on the one side, and on the
c~her side with their other ends eith-r at t~e vehicle 1 or
with the opposing scissors (Fig 4) by means of suitable
joints 32,33

Fig. 3 shows the point o~ linkage bet~een support scissors
and vehicl~ 1 (enlargemen~ af the le~t end of Fig. 2).
Universal joints o~ the kind shown ar~ known and consist of
a horizontal joint gudgeon 34 which is disposed in an - ~
S elastomeric material 35 in th~ bearer 36 (the joint is thus ~ -
a kind o~ cardan joint). The two legs cross at joint 39 and
are connected to gudgeon 34 by means ~f strap 40.
Fig. 4 finally shows, purely schematically, one of the
possi~ilities of coupling two ~r~ sci~sor ~nds, and that
in a way that produces a flexionally stif~ th~ vertical
direction) support also at the point of linkage.
Instead of the supporting scissors one could also employ :~
telescopic bearers of suitablQ construction for supporting
r~spectively uspending the central and auxiliary frames, ,.
5or onQ could use partly scissors and partly telescopic ~
supports. The scissors have th~ big ad~antage of the point ~ :
of support for the auxiliary fra~es moving proportionally~: :
and thus always taking the auxillary rrame into t~e optimal
positi~n (witho~t relative sliding movem~nt).
