Abstract

The passage arrangement is arranged between two coupled railway vehicles. It is separably connected at least at one end with the adjacent vehicle end 2 or 3. A central frame 11 is provided, and also walkable, hinged passage bridge parts 22, 23, 26, 27 (Figure 4, not shown). The passage arrangement 1 is supported and guided by the coupled (6) coupling parts 4, 5 of the two vehicle ends 2, 3. It may also be suspended on telescope-like supporting arms (31, 32 Figure 2 not shown) and guided by the coupled coupling parts of the two vehicle ends or suspended on telescope-like supporting arms and guided by second telescope-like guiding arms (39, 40 Figure 3). This passage arrangement is simple and serves for cases in which a frequent separation of the firmly coupled together vehicles or vehicle parts does not occur. <IMAGE>

Description

SPECIFICATION Passage arrangement, closed on all sides, between two coupled vehicles or vehicle parts The present invention relates to a passage arrangement, closed on all sides, between two coupled vehicles or vehicle parts, in particular railway vehicles, in which the passage arrangement at least on one end is separably connected with the end of the vehicle and a central frame is provided which is fixedly incorporated in the passage arrangement and is not intended for separation, with walkable, hinged transition bridge pieces, in which in each case a first bridge base is designed for orientable attachment to the two vehicle ends lying opposite each other and in which second bridge base flaps cover the first in operating condition so as to be slidably displaced, which second parts, divided centrally, are attached so as to be hinged on the central frame of the passage arrangement.

In the DE-PS 2 757 201 a passage arrangement is disclosed between two coupled vehicles connected to rails, which through its costly construction offers the passenger and the operator every comfort within the bounds of possibility. This passage arrangement has a separable central portal, in which the connection of each portal half with the associated vehicle end consists at least of an upper and a lower succession of various articulatedly constructed components.

For certain categories of vehicle the construction of the passage arrangement in the form shown in the DE-PS 2 757 201 is not necessary, particularly if vehicles or vehicle parts which are coupled together are separated from each other relatively rarely, or owing to the type of construction the separation of such vehicles is only possible under workshop conditions.

The aim of the present invention is the creation of a passage arrangement of the simplest type of construction for cases in which a frequent separation of the vehicles or vehicle parts which are firmly coupled together does not occur.

An inventive passage arrangement in this sense is distinguished in that the passage arrangement is supported and guided either by the coupled coupling parts of the two vehicle ends, or the passage arrangement is suspended on telescope-like supporting arms and is guided by the coupled coupling parts of the two vehicle ends, or else the passage arrangement is suspended on telescope-like support arms and is guided by second telescope-like guiding arms, in which the coupling parts are mounted on gimbals in the region of their associated vehicle ends and when in coupled state form a connection which is rigid in itself.

In addition, the central frame, standing in a normal plane, can be supported on the rigid coupling and guided therein. This supporting of the deadweight of the passage arrangement together with any usage loads on the coupling allows the arrangement to be of a lighter type of construction.

A further variant, which is based on this inventive conception, consists of the central frame being guided on the coupled coupling parts of the two vehicle ends and the passage arrangement being suspended on supporting arms which are arranged above its walkable part and are connected with the vehicle ends, preferably in the manner of a telescope.

In this embodiment, the coupling is relieved of the load from the passage arrangement together with any usage loads on the coupling, a condition which exists with couplings which have a very low loading capacity.

A further variant based on this inventive conception consists of this passage arrangement being suspended on supporting arms arranged above its walkable part and which are connected with the vehicle ends preferably in the manner of a telescope, and that the central frame is guided by second guiding arms, arranged beneath the walkable part of the passage arrangement and which are connected with the vehicle ends, preferably in the manner of a telescope. The construction is definitely to be provided if the coupling of the lightest type of construction may not be additionally stressed in any direction, ie. neither be dead loads nor by guiding forces.

These possible variations, which are based on one and the same inventive conception, result in an excellent adaptability to the most varied of vehicle constructions.

Example embodiments of the subject matter of the invention are explained in the following, by way of example, with the aid of a drawing, showing in diagrammatic representation: Fig. 1 a longitudinal section through two vehicle ends connected by a passage arrangement according to the invention, which is supported on the coupled coupling parts of the two vehicle ends and is guided by these, Fig. 2 a longitudinal section through two vehicle ends connected by another passage arrangement, which is guided by the coupled coupling parts of the two vehicle ends and is suspended on telescopelike supporting arms arranged above its walkable part, Fig. 3 a longitudinal section through two vehicle ends connected by a further variant of a passage arrangement, which is suspended on telescope-like supporting arms arranged above its walkable part and is guided by telescope-like guiding arms arranged beneath its walkable part, Fig. 4 a horizontal section along section line IV-IV of Fig. 1-3, through two vehicle ends connected by a passage arrangement according to Fig. 1 -3 in top view onto the walkable parts of the passage arrangement, Fig. 5 a variant of the embodiment according to Fig. 4, Fig. 6 the variant according to Fig. 5, with vehicle ends displaced with respect to each other in transverse direction.

The most significant variant embodiments in the sense of the present invention are shown in the following table and are provided with the corresponding reference numerals of the Figures.

T s%"r, " I It L Variant II suspended 1 (Fig. 2) guided Variant II / suspended (Fig. 3) t \ \ \ \ \ guided l\\\\\ \ \\\\ by coupled coupling on supporting on the guiding parts 4,5,6,9,10 arms 31,32 arms 39,40 The passage arrangement 1, closed on all sides, which is shown in Fig. 1, with two vehicle ends 2 and 3 in coupled state, allows the passengers and staff to move from one vehicle or vehicle part to the other as practicably as possible without hindrance and spatial restrictions, unharmed by external influences and without any danger.

Two coupling parts 4 and 5 of the two vehicle ends 2 and 3 are coupled to each other by means of a lock 6 and, in coupled state, form a connection which is rigid in itself, which is orientably mounted on gimbals by way of a bearing 7 in each case arranged on the vehicle end 2 and 3.

Here the distance 8 between the bearings 7 is the criterion for the kinematic conditions of the passage arrangement 1, by this being supported and guided via a support 9 with a bearing 10 such that on horizontal relative movement of the vehicle ends 2 and 3 with respect to each other, a central frame 11 completes an additional rotary movement about its vertical axis 12 instead of an exclusively lateral transverse movement, and hence the clear gangway width 13 of the passage arrangement 1 is retained fairly exactly.

Apart from the non-separable central frame 11, the passage arrangement 1 consists substantially of two protective membranes 14 and 15, which on one side enclose all around the central frame 11 and on the other side are connected with the vehicle ends 2 and 3 and thus form a whole unit which is in itself closed on all sides.

The protective membranes 14 and 15 in the present case are not the bellows which are subject to known disadvantages, but rather they are membranes formed out in a corrugated shape. The result therefore for their plane sections, apart from possibly in their immediate attachment areas, are section points of which the tangent pattern is constant, in contrast to the above- mentioned bellows, in which the tangent irregularly changes its value in the folds. In addition, the thick encircling protective membranes 14 and 15 form a reliable protection against external influences and therefore give the passenger an optimum sense of security when using the passage arrangement 1, whereas obviously bellows can only be produced with very thin material cross-sections in order to form satisfactory folds. The corrugated elastic protective membranes 14 and 15, in terms of their shape, are able to tolerate and accept all relative movements and their overlaps and, as regards their material quality they provide heat insulation and sound reduction, and are also flame- resistant and self-extinguishing.

The attachment of the protective membranes 14 and 15 is effected on the one hand to the central frame 11 and on the other hand to the vehicle ends 2 and 3 by means of connecting strips or tie rods resp. tension bands 16.

The passage arrangement 1 is positioned in its upper region by resilient elements 17, which are arranged on both sides between the central frame 11 and the vehicle ends 2 and 3.

In addition, the central frame 11 has a roof covering 18 facing the walkable part of the passage arrangement 1, and also laterally arranged holding bars 19.

The described passage arrangement 1 is asymmetrically separable and can be dismantled both selectively from the vehicle end 2 or 3 in a simple manner and also, for exchange purposes, can be detached from both vehicle ends 2 and 3 as an entire unit.

The passage arrangement 1 detached from one vehicle end 2 or 3 is held by a suspension apparatus 28, on which the central frame 11 is then suspended.

A further possibility of adaptation for the use of the passage arrangement 1 between two vehicle ends 2 and 3 is shown in Fig. 2, in which the central frame 11 is merely guided through the coupling parts 4 and 5 of the two vehicle ends 2 and 3, coupled together by means of lock 6, via a support 9 with the bearing 10, so that in the case of horizontal relative movements of the vehicle ends 2 and 3 with respect to each other, the central frame 11 completes an additional rotational movement about its vertical axis 12 in place of an exclusively lateral transverse movement, and hence the clear gangway width 13 of the passage arrangement 1 is retained fairly exactly, whereas otherwise the passage arrangement 1 is suspended on supporting arms 31 and 32 which are arranged above its walkable part with a bearing 29 rotatably about the vertical axis 12 on the portal frame 11 and connected with the vehicle ends 2 and 3 in the manner of a telescope and mounted on gimbals thereon with further bearings 33 and 34.

A further possibility of adaptation for the use of the passage arrangement 1 between the coupling parts 4 and 5 of the two vehicle ends 2 and 3, coupled by means of lock 6, is shown in Fig. 3, in which the passage arrangement 1 is suspended on supporting arms 31 and 32, which are arranged above its walkable part with the bearing 29 rotatably about the vertical axis 12 on the portal frame 11 and connected in the manner of a telescope with the vehicle ends 2 and 3 and mounted on gimbals thereon with the bearings 33 and 34, whilst the guidance of the passage arrangement 1 is effected by second guiding arms 39 and 40, which are arranged beneath its walkable part on the central frame 11 by means of lower bearings 35 and 36 and are connected in the manner of a telescope with the vehicle ends 2 and 3 and mounted thereon with bearings 37 and 38.

The walkable part of the passage arrangement 1 is shown in Fig. 4 and consists of the bridge base parts 22 and 23, arranged on the vehicle ends 2 and 3 so as to be orientable slightly upwards about their transverse axis through bearings 20 and 21, and slightly slanted toward the central frame 11, which bridge base parts, when let down, are slidably covered by the centrally divided bridge base flaps 26 and 27, which are arranged on the central frame 11 so as to be orientable about their transverse axis on both sides through the bearings 24 and 25.

The walkable part of the passage arrangement 1 is dimensioned, divided, and the elements coordinated to each other such that it allows the passenger to pass through without danger even with all the relative movements of the vehicle ends 2 and 3 with respect to each other.

The variant according to Fig. 5 and 6 relates to the interior of the walkable part of the passage arrangement and offers, both from the point of view of design, certain possibilities of adaptation to the interior fittings of the vehicles or vehicle parts and also offers the passenger greater comfort in the sense that side wings 41 and 42 are resiliently arranged in bearings 43 and 44 and through panelling pieces 45 and 46 which are attached to the central frame 11, they completely cover the lateral space between the walkable part of the passage arrangement 1 and the protective membranes 14 and 15. Through the resilient bearings 43 and 44 of the side wings 41 and 42, these are constantly pressed resiliently outward, so that with all relative movements of the vehicle ends 2 and 3 with respect to each other they rest against the panelling parts 45 and 46.

The mounting on gimbals of the coupling parts allow a three-dimensional movement. Ball-and-socket joints, multiple link joints, floating resilient bearings, make such movements possible.

The advantage of all the described arrangements lies in that the passage arrangement is guided such that with all the relative movements of the vehicle ends with respect to each other the central frame completes an additional rotational movement about its vertical axis instead of an exclusively lateral tranverse movement, and hence the walkable crossing bridge allows the passenger to pass through and to stop without danger, with all the relative movements of the vehicle ends with respect to each other, without any substantial restriction to the clear gangway width.
