Abstract
Description
Technical Field
[0001] The invention relates to a transition platform for a transition device between two vehicle parts, in particular rail vehicles or buses, which are movably connected to one another. The invention also relates to a transition device having such a transition platform. Background Art
[0002] Transition devices are used for the safe transfer of passengers between two vehicle parts of rail vehicles or buses. In the transition device, a transition platform is arranged on the bottom side, which, according to a common embodiment, has a step plate, which is located on two slide plates arranged laterally relative to the step plate, which slide plates themselves are attached to the vehicle parts. The step plate and in particular its upper side, which in the installed state points in the direction of the passage area formed by the transition device, serves as part of the walking surface for passengers when transferring between the vehicle parts.
[0003] During travel, the vehicle components of such an articulated vehicle exert different movements on one another. This results in swaying, bending and pitching movements. In particular, during swaying movements, i.e. twisting movements of two vehicle components relative to one another, the step plate tends to stand upright relative to the floor, with play possibly forming.
[0004] EP 2 161 176 EP discloses a step plate for a transition device, which is intended to be located on the floor of the respective vehicle component. An arm is provided on the underside of the step plate, which overlaps the respective floor of the vehicle from below and thereby prevents the step plate from being removed during a swinging movement of the vehicle component. The arm can be swiveled on the underside of the step plate via an axle. The arm can be pivoted out of the locking position by means of a rope, overcoming the spring force pressing the arm into the locking position. Thus, the step plate can be removed from the transition platform of the transition device. Conversely, the step plate can be installed by releasing the rope and pivoting the arm into the locking position by means of the spring force.
[0005] Such a rope is error-prone and can lead to an especially unreliable swinging back of the arm into the locked position. In addition, the rope may tear, so that the arm cannot be released from the locked position. The rope is also often easily accessible and can therefore be manipulated by unauthorized persons. Summary of the invention
[0006] Starting from this, the object of the present invention is to provide a transition device with a tread of the type mentioned at the outset, with which the pivot arm can be actuated simply and reliably, for example in order to ensure releasability from the locked position at any time and to provide protection against unauthorized intervention in the transition platform.
[0007] As a solution to this problem, according to the invention, a transition device with a step plate is proposed, the features of which are described in the following description. Advantageous developments of the invention are described in the description.
[0008] The invention includes the technical teaching that the rotary joint has an actuating device for pivoting the pivot arm, which can be actuated from the upper side of the tread in the installed state. The upper side in particular in the installed state points in the direction of the passage area formed by the transition device and forms the walkable surface of the tread.
[0009] By the operating means, it is possible to directly operate the pivot arm from the upper side of the tread. Thus, it is possible to simply and reliably operate the pivot arm and simplify the installation and removal of the tread.
[0010] According to an embodiment of the invention, the rotary joint and the actuating device are designed to be structurally integral with one another. In particular, it is proposed to provide a structural unit that can be arranged together on the tread. As a result, the already existing and necessary rotary joint is advantageously expanded in terms of its functionality and is used as an actuating device or is equipped with a device with which a pivot arm can be actuated.
[0011] According to an embodiment of the invention, the actuating device has a spanner profile for receiving a socket wrench and for rotating the actuating device about an axis of rotation. This makes it possible to selectively pivot the pivot arm into a locking position or an installation position by a simple rotational movement. The spanner profile can in particular have the shape of an external hexagon. Thus, when a tool is placed on the spanner profile, the pivot arm can be pivoted using a socket wrench with an internal hexagon as a standard tool.
[0012] The operating device can have a bolt which is rotatably arranged in the housing of the rotary joint. This ensures a safe and protected arrangement of the bolt and the rotatability of the bolt. For this purpose, the bolt can be supported in the housing. The housing can also serve as a rotation guide during the rotational movement of a tool, such as a socket wrench, when the operating device is operated. The housing serves in particular as a guide for the tool when it is placed on the operating device.
[0013] The housing can be held in a rotationally fixed manner in the receiving opening on the tread. This ensures a suitable arrangement and orientation of the rotary joint relative to the tread. Furthermore, the mounting of the rotary joint on the tread can thus be carried out more simply. Furthermore, the rotationally fixed connection between the housing and the tread can achieve that the actuating element with the pivot arm can be pivoted relative to the tread and simultaneously serve as a rotary joint.
[0014] According to an embodiment, a securing ring is arranged between the housing and the actuating device. The securing ring advantageously has an inner contour for receiving the wrench contour of the outer periphery of the actuating device in a form-fitting manner. Particularly advantageously, the securing ring fills the gap between the housing and the actuating device at least on the upper side. This ensures that no foreign matter and in particular no dirt can enter the gap between the housing and the wrench contour of the bolt.
[0015] The retaining ring can be moved axially in particular along the axis of rotation. Here, the retaining ring is preloaded in the direction of the upper side by means of the spring force of the spring element. What is ensured by the preload is that the retaining ring is always held in the gap between the housing and the operating device on the upper side. This prevents foreign matter and dirt from entering the housing and the rotating hinge through the gap. However, due to the downward axial mobility of the retaining ring, a tool can also be placed on the operating device to rotate the operating device with the pivot arm. When the retaining ring is pressed down along the axis of rotation in the direction of the pivot arm, the wrench contour and the housing can be used as a guide for the retaining ring and the tool is introduced into the gap.
[0016] It may also be advantageous if the housing has a slot and the retaining ring has a projection which projects into the slot of the housing and can be moved along the slot parallel to the axis of rotation. The retaining ring can be moved between two positions: a blocking position, in which the housing and the operating device are anti-rotatably engaged by means of the retaining ring, and a rotational position, in which the operating device can be rotated without being affected by the inner contour of the retaining ring. The projection is arranged in the slot of the housing not only in the blocking position but also in the rotational position. Preferably, the slot extends parallel to the axis of rotation and the projection is always arranged in the slot, so that the retaining ring cannot rotate around the axis of rotation. This achieves that the inner contour of the retaining ring is reliably locked with the wrench contour in the installation position and in the locking position.
[0017] According to an embodiment, the pivot arm is arranged on the bolt in a rotationally fixed manner. In particular, the pivot arm is connected to the bolt in a form-locking manner around the rotation axis. This allows a reliable torque transmission from the bolt to the pivot arm.
[0018] The pivot arm is preferably arranged centrally on the bolt and is designed to be so long that the pivot arm overlaps the slide plate of one of the vehicle components from below with each of its arm end regions. Thus, the number of components remains very small and ensures that the tread is particularly reliably held.
[0019] The operating device can have a mark for indicating the rotation state of the pivot arm. With the help of the mark, the operator can determine whether the pivot arm is in the locking position or in the installation position. This simplifies installation and inspection.
[0020] Preferably, the tread and the rotary joint form a walking surface on the upper side. Form a substantially flat surface thereby, through which the passenger can easily and smoothly cross this surface.
[0021] The tread can have a pin which is used to be arranged in a complementary gap in one of the slide plates. This simplifies the positioning of the tread relative to the slide plate. In addition, this prevents incorrect positioning and / or lateral misalignment of the tread in the transition device.
[0022] The pivot arm can have a slide at its end, which is used to press on the respective slide. The slide is preferably made of plastic and has an entry bevel on the side, so that the end side of the pivot arm can be simply pivoted to the bottom side of the slide, and there, the entry bevel builds up tension on the pivot arm, so that the tread is prestressed relative to the bottom side of the slide. This ensures, on the one hand, a secure mounting of the tread with the pivot arm on the vehicle component with the slide, and, on the other hand, a secure placement of the tread on the slide of the vehicle component under prestressing. Here, the prestressing is ideally large enough to achieve a secure placement and minimize the risk of a gap between the tread and the slide. At the same time, however, the prestressing is only large enough to allow the pivot arm to be swiveled with reasonable force expenditure.
[0023] According to an embodiment, at least two pivot joints are provided, which are arranged spaced apart from each other in the longitudinal direction of the tread. Specifically, the two pivot joints can be arranged on opposite sides of the tread, so that the tread engages with the respective slide plate at two locations. As a result, the tread can be effectively prevented from being removed from the lateral slide plate, especially during a swinging movement of the vehicle.
[0024] The invention furthermore relates to a transition device for being arranged between two vehicle components which are movably connected to one another, which transition device has a transition platform, wherein the transition platform embodies the above-described features.
[0025] Advantageous improvements of the present invention are obtained from all elements, descriptions and drawings of the present application. The advantages of the combination of features and multiple features mentioned in the description are only exemplary and can be used alternatively or repeatedly without having to be implemented by the embodiments according to the present invention.

[0034] Figure 1 A transition platform 1 according to the invention with a tread 10 is shown in a perspective view. The tread 10 rests on two slides 12, 14 of two vehicle components that are movably connected to one another. Seen from the upper side 21 of the tread 10, a rotary joint 18 and a respectively assigned actuating means 20 for rotating a pivot arm (not visible here) are arranged on the tread 10. When the vehicle components are moved, the slides 12, 14 slide under the tread 10, so that a gap-free walking surface is always formed for transferring passengers between the vehicle components. The walking surface is formed by the upper side 21 of the tread 10 and the slides 12 and 14.
[0035] Figure 2The slide plates 12, 14 and the tread plate 10 are shown in a perspective view from below in the installed state. The pivot arm 16 arranged on the rotary joint 18 is shown here, which is pivoted below the slide plates 12, 14 in the locked position and extends approximately transversely to the longitudinal extension of the tread plate 10. Each pivot arm 16 here overlaps a slide plate 12, 14 from below, which is thus respectively clamped between the underside of the tread plate 10 and the pivot arm 16. In addition, the pin 38 of the tread plate 10 is arranged in the slot 40 of the slide plate 14 and holds the tread plate 10 in position relative to the slide plate 14.
[0036] Figure 3 The pivot joint 18 with the pivot arm 16 is shown in a perspective view from the top and bottom. The pivot joint 18 comprises a housing 26, which has an actuating device 20 arranged therein in a rotatable manner and designed as a bolt 48. The bolt 48 is connected to the pivot arm 16 in a rotationally fixed manner and is axially held on the pivot arm 16 by means of a bolt 50 and a washer 52. A retaining ring 28 is arranged between the bolt 48 and the housing 26. The slide 42 is arranged on the arm end region of the pivot arm 16. The slide 42 has an inclined portion 54 on its side. The inclined portion 54 enables simple sliding onto the slide plate when the pivot arm 16 is swiveled.
[0037] Figure 4 The pivot joint 18 with the pivot arm 16 is shown in a top view. The bolt 48 is arranged in the housing 26 of the pivot joint 18 in a manner that it can rotate about the axis of rotation 24. The bolt 48 has a key profile 22. The key profile 22 is an external hexagonal key profile, so that a socket wrench can be inserted into the key profile 22 of the bolt 48. The bolt 48 and the pivot arm 16 connected thereto in a rotationally fixed manner can be rotated with the socket wrench. A stop ring 28 is arranged between the housing 26 and the key profile 22 of the bolt 48, and the stop ring can be pressed into the housing 26 along the axis of rotation 24 when a tool is placed. The stop ring 28 is loaded with a spring force, so that it completely fills the gap between the bolt 48 and the housing 26 and prevents foreign matter and dirt from entering the housing 26.
[0038] Figure 5 The swivel joint 18 with the swivel arm 16 is shown in a side view. The swivel arm 16 can be pivoted about the swivel axis 24 by means of a swivel movement of the actuating element. The swivel arm 16 is arranged on the swivel joint 18 by means of a screw 50 and a washer 52. The housing 26 has a flange 56. A lock nut 58 is screwed onto the housing 26 so that the housing 26 can be fixedly arranged in a receiving opening in the tread plate by tightening the lock nut and clamping the tread plate between the lock nut 58 and the flange 56, while the housing 26 is introduced into the receiving opening of the tread plate.
[0039] Figure 6The pivot joint 18 with the lock nut 58 and the pivot arm 16 is shown in an exploded view. The pivot joint 18 and the actuating means 20 are constructed as a structural unit, which has the following components: housing 26, actuating means 20 designed as a bolt 48 and a retaining ring 28, bushing 60, bolt 50 and washer 52. The lock nut 58 can be screwed onto the housing 26. The bushing 60 is located between the housing 26 and the bolt 48 and forms a receptacle and a sliding surface for rotating the bolt 48 relative to the housing 26 about a virtual axis of rotation 24. Starting from the upper side 21, the spanner contour 22 is formed on the bolt 48. At the end of the bolt 48 opposite the spanner contour 22, the bolt has a flattened portion 62 for receiving a slot hole 64 of the pivot arm 16 in a form-fitting manner. The bolt 48 has a marking 36 on its upper side 21 for indicating the rotation state of the bolt 48 with the pivot arm 16 arranged thereon. The stop ring 28 has on its inner side an inner contour 30 for positively accommodating the wrench contour 22 of the bolt 48. The stop ring 28 also has a stop 66 for abutting against a projection 68 of the bolt 48. Projections 34 for being arranged in a slot 32 of the housing 26 protrude on the outer periphery of the stop ring 28. The slot 32 extends parallel to the axis of rotation 24 in the housing 26.
[0040] Figure 7 Finally, according to Figure 4 The detailed view of the side cut through the section line BB of shows the rotary joint 18 with the pivot arm 16 arranged thereon. The rotary joint 18 is arranged in the receiving opening 70 of the tread 10 and is held on the tread 10 in a rotationally fixed manner by means of the housing 26, by means of the flange 56 and the lock nut 58.
[0041] The pivot arm 16 is connected to the bolt 48 in a rotationally fixed manner and is held on the bolt 48 by means of a bolt 50 and a washer 52. Therefore, the bolt 48 can be twisted relative to the housing 26 and the tread 10 around the axis of rotation 24 by means of the pivot arm 16. The axis of rotation 24 is oriented orthogonally to the walking surface. The pivot arm 16 can swing in a plane parallel to the walking surface. The bushing 60 forms a receiving portion and a sliding surface between the housing 26 and the bolt 48 for the bolt 48. The stop ring 28 is arranged in the sliding groove 32 of the housing 26 with its projection 34. Loaded with a spring force, the stop ring 28 is pressed into the blocking position I and held there.
[0042] In the blocking position I, the stop ring 28 surrounds the wrench contour 22 of the bolt 48 with its sliding groove 32 in a form-locking manner. Here, the projection 34 is located in the sliding groove 32, and the stop ring 28 causes a form-locking, anti-rotational engagement between the housing 26 and the bolt 48, thereby preventing rotation or swiveling around the axis of rotation 24. The stop ring 28 forms a lock here. In the blocking position I, the stop ring 28 is flush with the bolt 48, the housing 26 and the step plate 10 on the upper side 21, and can completely fill the gap between the bolt 48 and the housing 26. This prevents, for example, foreign matter or dirt from entering the interior of the housing 26, and the bolt 48 is fixed to prevent twisting in the housing 26. In the blocking position I, the stop 66 squeezes the projection 68 of the bolt by means of a spring force. This forms a form-locking counterpart, which prevents the stop ring 28 from popping out of the housing 26.
[0043] When the socket wrench is moved along the rotation axis 24 onto the wrench contour 22 of the bolt 48, the stop ring 28 is pressed along the rotation axis 24 away from the upper side 21 in the direction of the pivot arm 16. Here, the stop ring 28 is guided on the housing inner wall 72 and the sliding groove 32. When the stop ring 28 is pressed down into the rotation position II by the operator with the aid of a tool, the inner contour 30 of the stop ring 28 is separated from the wrench contour 22. As a result, the form-locking and torque-rigid connection between the housing 26 and the bolt 48 is also released. As a result, the bolt 48 and the pivot arm 16 can be freely swiveled and can be swiveled between the installation position and the locking position.
[0044] The present invention is not limited to the preferred embodiments described above in its embodiment. Rather, many variants are conceivable, which can also use the shown solution even in fundamentally different embodiments. All features and / or advantages (including structural details or spatial arrangements) derived from this application are important for the present invention, whether individually or in various combinations.
