Definitions

• the present invention relates to a transition device between all coupled vehicles, in particular rail vehicles, which is closed on all sides by means of a bellows casing, which device consists of two base parts which can be changed in length, each of which is connected at one end to one of the vehicles , while at least parts of the free ends of the two base parts are separably connected to one another, each base part having foldable transition bridge parts, a bellows-shaped covering part, and optionally a ceiling cladding, and circumferential, coupled central frames are arranged on the free ends of the covering parts, either from below or are supported or supported at the top by at least two supports which extend between the vehicles, are variable in length and act essentially in a horizontal plane.
• Transition devices between two coupled rail-bound vehicles are known in a wide variety of designs. Also known are the many problems that occur with such transition devices.
• One of the problems is to support the device, which now consists of one or two base parts, in such a way that the transition is as simple as possible and problem-free for the user.
• the transition device must either be supported from below or, if necessary, be suspended from a complex device.
• problems have recently arisen in that the transitions are relatively short and are used between vehicles which are also used for relatively small curve radii. The problem arises here that the support from below of the transition, at least in the important central part, becomes insufficient or at least unreliable.
• the object of the present invention is to provide a transition device of the type defined at the outset, which ensures a largely problem-free transition with a simple design effort. This object is achieved according to the invention in a transition device of the type mentioned at the outset by the features defined in the characterizing part of claim 1.
• auxiliary frames and their interaction with the supports results in reliable carrying either from below or above the central frame, the auxiliary frame and thus the transition cladding parts and above all the foldable bridge parts.
• the supports designed as scissors and / or telescopic supports an inevitable angular transmission to these supports takes place, regardless of the curve radius or the angle division between the two coupled vehicles, which in turn ensures optimal support of the actual transition device. If this effect is desired or required lent, it can be achieved in the case of supporting structures in telescopic form by additional guide elements, for example in the form of scissors.
• FIG. 1 shows a transition device according to the invention, which is shown in an exploded view to clarify the structure and the individual components;
• Fig. 3 shows a gimbal linkage of scissors to a vehicle
• Scissor ends in the area of the pivot and base below the central frame.
• Each base part has foldable transition bridge parts 3 and 4, furthermore a ceiling cladding 5 and 6 as well as a bellows-shaped covering part 7 and 8, respectively.
• the wrapping parts 7, 8 each have at their free ends a circumferential central frame 9 or 10, which are connected to one another via suitable coupling means, for example coupling rods 11 or 12.
• a peripheral auxiliary frame 7 ', 8' is provided in the middle of each wrapping part 7, 8, which provides a guarantee for the optimal functioning of the transition.
• Each transition bridge part 3 or 4 in turn consists of two parts 3 ', 3 "or 4', 4", of which one 3 'or 4' on the associated vehicle 1 or 2 and the other on the central frame 9 or 10 is articulated.
• the part 3 'or 4' articulated on the vehicle 1 or 2 rests on the associated subframe 7 'or 8', while the second part 3 " or 4 "lies down on the first part 3 'or 4'.
• the central frames 9, 10 and the auxiliary frames 7 ′, 8 1 are supported from below by supports in such a way that they are able to absorb both the weight of the transition device and the maximum loads that can occur (by people using the transition).
• supports in such a way that they are able to absorb both the weight of the transition device and the maximum loads that can occur (by people using the transition). The type of these supports is explained in more detail below.
• Swinging wings 13, 14 and 15, 16 are articulated to the vertical posts of the door openings of vehicles 1 and 2, which swivels with corresponding swiveling wings 13 ', 14' and 15 ', 16', respectively on the vertical bars of the frames 9, 10 overlapping against the casings 7, 8 or the auxiliary frames 7 *, 8 'as soon as the device is assembled.
• These swivel wings also have elastomeric parts which bear against the transition bridge parts 3, 4 or the ceiling cladding 5, 6.
• a transition device is thus formed, in which the passage through the swivel wing or bridge parts and ceiling formwork is completely boarded and the whole is surrounded by a bellows-like covering.
• the central frames 9, 10 and the auxiliary frames 7 ', 8 * of the transition device are supported by supports which can be changed in length, preferably by multi-section scissors 17, 18 and 19, 20.
• the multi-section scissors 17, 18 and 19, 20 act in a horizontal plane and are each coupled via a gimbal joint (see Fig. 3) to one of the vehicles and, on the other hand, with their free ends coupled to scissors directly opposite via a vertical joint pin ( Fig 4).
• the vertical hinge bolts at the connection point and the likewise vertical hinge bolts of the scissors per se, with suitable dimensioning of the scissor arms, result in a support that is absolutely rigid in the vertical direction between the two vehicles 1, 2.
• the central frames 9, 10 are articulated between the casings 7, 8 and the ceiling claddings 5, 6 with a guide 21, 22 or 23, 24 which can be changed in length on the associated vehicles.
• These guides are preferably also designed as scissors, these scissors centering the auxiliary frames 7 ', 8 * and guiding the central frame 9, 10.
• the transition device is properly supported in practically every conceivable angular position of the two vehicle parts with respect to one another.
• the transition supported in this way is perfectly closed on all sides, thus protected against all external influences (drafts, noise).
• Fig. 2 shows the schematic structure and the effect of the support scissors in the horizontal plane.
• the scissor arms 25, 26 intersect in the joint 27 and are designed as continuous rigid supports.
• the arms 28, 29 and 30, 31 are articulated on the one hand via vertical hinge pins on the arms 25, 26 and, on the other hand, are coupled with their other ends via corresponding joints 32, 33 either to the vehicle 1 or to the scissors opposite (FIG. 4).
• Fig. 3 shows the coupling point between a pair of support scissors and the vehicle 1 (enlargement of the left end of Fig. 2).
• Gimbals of the type shown are known and consist of a horizontal hinge pin 34 which is arranged in an elastomeric mass 35 in the carrier 36 (the hinge is thus a type of gimbal suspension).
• the two arms intersect in the joint 39 and are connected to the pin 34 via the tab 40.
• telescopic supports of suitable construction could be used to support or suspend the central and auxiliary frames, or it could be partly scissors and partly telescopic supports.
• the 7 scissors have the great advantage that the support point for the subframe shifts proportionally and thus always takes the subframe into the optimum position (without relative sliding movement).
