DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] The communication passage shown in FIG. 1 has the reference numeral 1. The communication passage 1 is connected with the car bodies 4, 5 by consoles 2, 3 wherein the car bodies are only schematically indicated. The communication passage 1 is an integral part of a passage between to articulated vehicles which usually still comprises a bellows (not shown) which extends between the front walls of the car bodies 4, 5 of the vehicles or vehicle parts. The bellows can surround the communication passage in a tunnel-shaped, i.e. U-shaped manner, here or it can also be formed in a box-shaped, closed manner.

[0029] The communication passage 1 comprises each a bridge plate 6, 7 located on the console 2, 3 wherein the treadplate designated with 8 is mounted on the bridge plates 6, 7. The treadplate 8 can be divided in the center with two identical communication passage halves occurring with respect to the communication passage 1 when the communication passage is divided. The treadplate halves have the reference numeral 8a, 8b.

[0030] FIG. 2 shows a view from below on the communication passage 1. Visible are again the two consoles 2, 3 which are connected with the car bodies 4, 5. The consoles 2, 3 each show two spiral springs 10 spaced apart from each other wherein the spiral springs 10 ensure that the respective bridge plate 6, 7 is pressed against the underside of the treadplate 8 in order to keep the corresponding bridge plate and the treadplate halves 8a, 8b in the horizontal in the case of division of the communication passage, for example, when decoupling two vehicle parts, and thus when dividing the passage.

[0031] Moreover, the consoles 2, 3 receive the two scissor-type frames 20 extending in parallel to each other. As has already been explained, the scissor-type frames 20 are in principle identical to each other. The plane of extension is identified by the arrow 90. Each scissor-type frame 20 comprises a first segment 22 and a second segment 24. As can be seen, the first and the second segments 22, 24 of each scissor-type frame 20 are facing each other diagonally. The first and the second segment 22, 24 are coupled by the pivoting bearing designated with 25. The connection of the scissor-type frames 20 with the consoles 2, 3 occurs by swivel bearings 15. It is provided here in detail that each segment comprises a first scissor arm 26 and a second scissor arm 27 which are rotatably received by the swivel bearing 15. The first and the second scissor arm 26, 27 are hinge-linked with a third scissor arm 28 and a fourth scissor arm 29, as this can be seen directly in FIG. 2. At the end, the third and fourth scissor arm 28, 29 are brought together in the pivoting bearing 25. In the area of the pivoting bearing 25 the coupling device designated with 60 is provided.

[0032] The scissor arms 26, 27, 28, 29 themselves comprise insertable intermediate members 80 by which the scissor arms 26, 27, 28, 29 can be adjusted in their length, and thus the length of the segments, to the length of the passage. This means that the intermediate members have an adapter function.

[0033] If one now considers FIG. 3, which shows a first segment 22 and a second segment 24, which are hinged to the console 2, 3 by the swivel bearing 15 extending in parallel to each other. Moreover, the first and second scissor arms 26, 27 located on the swivel bearing 15 can be seen, which are hinge-linked with the third scissor arm 28 and the fourth scissor arm 29. The pivoting bearing designated with 25 is formed by the two pivoting bearing halves 31, 41 of the first segment 22 and the second segment 24. In detail, the pivoting bearing half 31, 41 comprises a first U-shaped pivoting bearing head 33, 43, wherein between the legs 33a, 33b and 43a, 43b of the U-shaped first pivoting bearing head the second pivoting bearing head 35, 45 is mounted which is part of the third scissor arm 28. The first pivoting bearing head 33, 43, which is U-shaped, is part of the fourth scissor arm 29. Moreover, the first pivoting bearing head 33, 43 is connected with the second pivoting bearing head 35, 45 by two guidances 36 which are formed in the manner of a tongue and groove connection. By the two guidances 36, which are arranged between the two pivoting bearing heads 33, 35, 43, a guidance in radial direction is achieved.

[0034] Moreover, the pivoting bearing half 41 receives the pivot pin 39, as it can likewise be seen in FIG. 3.

[0035] The first segment 22 is formed substantially identical to the second segment 24. A difference exists only in that the first pivoting bearing head 33 of the first segment 22 on the upper and lower end respectively has a protrusion 37 and comprises a coupling groove 40, which, similar to the pivot pin 39, in connection with the coupling device 60 serves for connecting a first and a second segment in order to form a scissor-type frame. The segments can hence also be designated as a first positive and a second negative segment.

[0036] As has already been explained elsewhere, in FIG. 3 only a first and a second segment 22, 24 are shown. It is pointed out that an entire scissor-type frame is comprised of at least a first and at least a second segment 22, 24. This means that the first segment 22 according to FIG. 3 for the formation of an entire scissor-type frame is connected with the second segment 24 in the area of the pivot pin 39 by the coupling device in order to form the pivoting bearing. The advantage of this crosswise arrangement of first and second, hence positive and negative segments on the respective consoles 2, 3 is that by this always a coupling possibility exists which is of particular interest, if, for example, as it has been explained elsewhere, the scissor-type frames are arranged in the area of a passage between two articulated vehicles or vehicle parts, wherein it shall be possible to couple the vehicles or vehicle parts of such an articulated vehicle among each other in any way.

[0037] If one now considers FIG. 4, one can see the embodiment of the coupling device designated with 60. The first positive and the second negative segment 22, 24 comprise here at the end each one positive and one negative coupling member 62, 64 with the two coupling members 62, 64 forming the coupling device 60. Moreover, the positive coupling member 62 comprises two coupling fingers 63 placed one above the other, which engage into the coupling groove 40 located at the upper end and at the lower end of the first pivoting bearing head 33 which coupling groove is mounted in protrusion 37 (FIG. 3).

[0038] Correspondingly, the negative coupling member 64 with the coupling eyes 65 placed one above the other and spaced apart receives the pivot pin 39. In order to produce an entire scissor-type frame 20, the positive and the negative coupling member 62, 64 are now engaged with each other with the locking pin designated with 70 engaging into the corresponding pin opening 72 of the corresponding coupling member 62, 64. The locking pin 70 comprises an opening 71 into which the locking member 75 can be inserted with the locking bolt 76. This means that the positive coupling member 62 is coupled with the negative coupling member 64 at both ends by the locking member 75 in connection with the locking pin 70.

[0039] Not only the positive but also the negative coupling member 62, 64 are connected with the treadplate 8 for guidance of the treadplate by fixed bearings and movable bearings 66, 67. In detail, the positive coupling member comprises two threaded cams 66 as fixed bearings and the negative coupling member comprises two head bolts 67 as movable bearings for connection with the treadplate 8.

[0040] As has already been set forth, FIG. 5 shows in this connection schematically the arrangement of the side wall covering 120 on both sides of the bellows 100 on the inside of the bellows as well as the roof covering 140 likewise on the inside of the bellows 100. For the sake of clarity, the bellows has been omitted in the FIGS. 1 to 4. The hinged connection below the communication passage 1 has the reference numeral 150. With respect to the side wall covering and with respect to the roof covering it has to be said that both are formed substantially in the same manner as the communication passage 1. With respect to the description of the individual component parts and/or the construction, reference is expressly made insofar to what has been said regarding the FIGS. 1 to 4. Hence, for better understanding, the side wall covering is substantially nothing else than a communication passage, rotated by 90, with the at least one scissor-type frame being provided behind the side wall covering 120. The side wall covering 120 each comprises a side wall bridge plate 126, 127 located on the front of each vehicle which side wall bridge plates are spaced apart from each other and which are bridged over by the connecting plate 128. The connecting plate 128 is connected with the at least one scissor-type frame 20.

[0041] The same applies to the roof covering 140 with the roof bridge plates 146, 147 and the connecting plate 148 for bridging over the distance between the two roof bridge plates 146, 147.

[0042] Here, the plate-like element 128, 148 of the side wall covering and the roof covering corresponds to the treadplate 8 of the communication passage; the side wall and the roof bridge plates 126, 127; 146, 147 are to be equated with the bridge plates 6, 7.

[0043] FIG. 6 shows in plan view two scissor-type frames for centering of the central frame 200 of a bellows with two bellows halves. The two scissor-type frames 20 are connected with the central frame 200 in the area of the pivoting bearing 25 in particular by the coupling device 60. The central frame can be formed by two coupling frames with one coupling member 62, 64 being allocated to each coupling frame. The scissor-type frames are formed in the same way as the scissor-type frames of the communication passage. Insofar. reference is made to them. Connection of the at least one scissor-type frame in each case occurs as for the communication passage, the side wall and the roof covering also by consoles 2, 3.
