Definitions
- Guide rails are used in elevator systems to guide elevator cars along a hoistway.
- Lift shafts traditionally extend vertically in a building. Occasionally, however, already proposed horizontal manholes. Due to the large shaft lengths, the guide rails are typically assembled from individual rail elements during assembly.
- the rail elements along the vertical direction of travel are in abutment with each other and at the same time an expansion of the guide rail in the vertical direction is made possible with temperature fluctuations.
- the composite guide rail thus behaves like a continuous guide rail.
- a new type of elevator installation uses a linear motor for driving the elevator cars inside the elevator shaft.
- a primary part of the linear motor is attached to the rail elements and a secondary part of the linear motor on the elevator car to be moved.
- This drive mode makes it possible to simultaneously move several elevator cars in the same shaft independently.
- guide rails are equipped with the primary part of the linear motor. This additional weight must be absorbed by guide rails.
- this proportion also multiplies.
- the concept of stacked rail elements is no longer practicable because the lowermost rail elements can not absorb the load of the overlying rail elements.
- the rail elements must therefore be connected individually to the shaft wall.
- the drive concept of the linear motor still leads to another problem.
- the primary part heats up during operation. Since the primary part is attached to the rail elements, the heat is dissipated to the rail elements, resulting in a much higher thermal expansion. In order to take this into account, adjacent rail elements must be at a distance from each other (so-called expansion joint).
- an elevator car typically has a plurality of guide rollers that roll along a track of the guide rail.
- a jaw brake may be provided in which the elevator car is braked by one or more brake shoes acting on the guide rail from the elevator car. As soon as such components change between two adjacent rail elements, it comes to shaking and noise due to the distance.
- Object of the present invention is to reduce such shocks and noise.
- a guide rail for an elevator installation comprising at least two rail elements, which together form a guide rail section with a functional track in a direction of travel.
- each of the rail elements is connected to the shaft wall, wherein adjacent rail elements have a distance from one another, so that the rail elements can expand thermally in the direction of travel freely.
- at least two of the adjacent rail elements in the region of the functional raceway have mutually opposite boundaries which have such a complementary profile that any desired, perpendicular to the direction of travel, cross section of the guide rail section extends in the region of the functional raceway through at least one of the two adjacent rail elements.
- the functional track is understood to be the area of the guide rail on which the corresponding components slide along, grind along or roll off during operation of the elevator installation.
- the functional track is a rolling track for a guide roller of an elevator car.
- the invention ensures in particular that the guide roller remains permanently in contact with the guide rail. There are no jumps at the transitions of rail elements, which could cause vibrations or noises.
- the arbitrary, perpendicular to the direction of travel, cross section in the region of the rolling track preferably has an extent which corresponds to at least 20% of the extent of the rolling track perpendicular to the direction of travel. This has the advantage that there is always enough contact between guide roller and guide rail.
- a rolling guide roller is in contact with the guide rail along a line corresponding to a cross section perpendicular to the direction of travel. A cross section of more than 20% of the extent of the rolling track thus leads to at least 20% of the possible contact surface of the guide roller is in contact with the guide rail.
- the two adjacent rail elements in the region of the rolling track on meshing comb-shaped formations on meshing comb-shaped formations.
- this embodiment makes it possible to thermally expand adjacent rail elements by sliding the comb-shaped formations of the two adjacent rail elements into one another when thermally expanded.
- good contact with the leadership role is ensured.
- the leadership role in unrolling at any time contact with all comb-shaped formations of at least one rail element.
- the contact areas between the guide roller and the elevator rail are always distributed over the entire width of the guide roller.
- the leading role is not just left or right. This leads to a particularly uniform rolling of the leadership role.
- a first rail element of the at least two adjacent rail elements has a first bolt on which a first plurality of strung on the first plates, which form the comb-shaped formations of the first rail element.
- a second rail element of the at least two adjacent rail elements has a second bolt, on which a second plurality of second plates is strung, which form the comb-shaped formations of the second rail element.
- the first plurality of first plates each have a slot through which the second bolt extends and the second plurality of plates each have a slot through which the first bolt extends.
- the comb-shaped formations not only engage with each other, but it is also a positive connection between the rail elements produced.
- the first rail element is connected via the first bolt with the first plates and the second plates.
- the first plates and second plates are additionally connected via the second bolt to the second rail element.
- both first and second plates are alternately lined up on both bolts.
- the first plates are rotatably mounted on the first and second bolts and the second plates are rotatably mounted on the first and second bolts.
- inaccuracies in the assembly of the rail elements can be compensated.
- adjacent rail elements are not 100% aligned with each other, but have a minimum offset from each other.
- This can for example mean that the rolling track on the first rail element has a slightly greater distance from the elevator car than the rolling track on the second rail element. Along the rolling track so there would be a staircase-like offset, resulting in unwanted noise when rolling the guide roller.
- This can be compensated by the rotatable arrangement of the plates on the bolt. If there is an assembly offset described above, then the stack of first and automatically inclined and thus compensates for the offset along the rolling track. This results in a steady Abrolllaufbahn, which favors a low-noise rolling.
- first and second plates are oriented and arranged such that the narrow sides of the first and second plates together form part of the functional raceway of the guide rail section. This allows a particularly simple and compact design and at the same time a particularly uniform distribution of the contact areas between the guide roller and the elevator rail at each cross section over the entire width of the guide roller.
- the opposing edges have a step-shaped course or run the opposite boundaries at an angle of less than 70 ° to the direction of travel.
- This also has the advantage that there is always a sufficiently large contact between the guide roller and one of the rail elements of the guide rail.
- these embodiments have the additional advantage that the two rail elements can be pivoted against each other. A pivoting of rail elements to each other is helpful if the direction of travel of an elevator car is to be changed from vertical travel to horizontal travel. In certain variants for realizing such a change in direction, this can be made possible for example by pivoting rail elements. An example of this can be found in JPH0648672.
- the opposing edges have a chamfer and / or curvature in the area of the functional raceway. This results in a funnel-shaped course along the functional career.
- This has the advantage that the butt edges are reduced in a non-ideal adjustment of the rail elements after a pivoting operation. For example, there may be some misalignment between the adjacent rail elements or an inclination between adjacent rail elements.
- the functional track is a brake raceway for a shoe brake of an elevator car.
- a braking track is understood to be the area of the guide rail on which a brake shoe of a shoe brake, which acts between the elevator car and the guide rail, grinds along during the braking process.
- one of the at least two adjacent rail elements may have a pin which engages in an associated blind hole of the other rail element of the at least two adjacent rail elements. The two rail elements are connected in a sense in the field of braking career.
- a shoe brake acts on the guide rail in the region of the braking track. This leads to a certain deformation of the guide rail in this area.
- the braking distance of the elevator car extends over several consecutive rail elements. As long as the jaw brake acts only on a rail element and not on the adjacent rail element, it would therefore come without the pins to a deformation of the former rail element but not to a deformation of the adjacent rail element. Consequently, no uniform braking process would be guaranteed, since an offset of the rail elements in the region of the brake track is created by the braking effect.
- the guide rail comprises at least two rail elements, which together form a guide rail section with a functional track in a direction of travel.
- each of the rail elements is connected to the shaft wall and adjacent rail elements are at a distance from each other, so that the rail elements can expand thermally in the direction of travel freely. Furthermore, a wedge-shaped transition piece is arranged between the two adjacent rail elements, which is mounted movably perpendicular to the direction of travel.
- the wedge-shaped transition piece By disengaging the wedge-shaped transition piece ensures that the two adjacent rail elements can thermally expand in the direction of travel.
- the three elements arranged one behind the other in the direction of travel (rail element, transition piece, rail element) are always in contact with each other, so that there is a continuous transition without a gap.
- at least two of the adjacent rail elements in the region of the functional raceway have opposite boundaries which are rectilinear and at an angle to one another, which corresponds to the wedge angle of the wedge-shaped transition piece. In this way, a smooth transition between the adjacent rail elements and the transition piece is achieved because the wedge-shaped transition piece is fitted exactly in the space between the adjacent rail elements.
- the functional track extends over the wedge-shaped transition piece.
- the full width functional race on the wedge-shaped transition piece is independent of whether the wedge-shaped transition piece is engaged or disengaged.
- the wedge direction extends at an angle to the direction of travel, which is between 70 ° and 110 °.
- the angle to the direction of travel is 90 °.
- the wedge angle is preferably in the range of 50 ° to 70 °.
- the wedge-shaped transition piece can be oriented symmetrically, so that both sides, which adjoin the adjacent rail elements, have the same, in particular acute, angle to the direction of travel.
- the wedge-shaped transition piece may also be oriented asymmetrically. For example, one of the two surfaces at an angle of 90 ° to the direction of travel and the other side at an angle to the direction of travel. It is only important that a glide across the direction of travel is made possible.
- the angle ranges have the advantage that the wedge-shaped Transition piece is acted upon expansion of the adjacent rail elements with a sufficient force to cause the disengagement against the wedge direction.
- the wedge-shaped transition piece is biased against the wedge direction. This has the advantage that the wedge-shaped transition piece is automatically engaged by the bias in a thermal contraction. Upon thermal contraction, the gap between the adjacent rail elements increases, allowing the wedge-shaped transition piece to be more strongly engaged. The bias ensures that this engagement happens automatically.
- the guide rail comprises a compression spring which extends between the blunt end of the wedge-shaped transition piece and a holding device.
- the compression spring allows in a simple manner, the aforementioned bias of the wedge-shaped transition piece against the wedge direction.
- the compression spring exerts a spring force on the wedge-shaped transition piece.
- the spring force has at least one force component in the wedge direction. In this way, the bias of the wedge-shaped transition piece results against the wedge direction.
- a guide is provided between at least one of the at least two rail elements and the wedge-shaped transition piece.
- the wedge-shaped transition piece is movably mounted.
- the guide ensures that the wedge-shaped transition piece performs a well-defined translational movement with a thermal change in length of the rail elements.
- the guide ensures that no offset occurs between the one of the at least two rail elements and the wedge-shaped transition piece.
- a uniform and continuous functional career is also present in the region of the transition between the at least one of the at least two rail elements and the wedge-shaped transition piece.
- a guide is provided between the two adjacent rail elements and the wedge-shaped transition piece arranged therebetween.
- the guide is designed as a tongue and groove connection. This is easy to manufacture and allows reliable leadership.
- a dovetail guide or a guide with a T shaped cross-section can be used.
- Such guides have the advantage that not only compressive forces can be transmitted to the wedge-shaped transition piece, but also tensile forces.

- the guide rail 9 is composed of rail elements IIa, I Ib, 11c, l ld, l le.
- Rail elements IIa, IIb, 11c, l ld, l le are each attached to the shaft wall 5.
- each rail element IIa, IIb, 11c, lld, ll a fixed bearing 15 and a floating bearing 17.
- the floating bearing 17 leaves a movement of the rail elements I Ia, I Ib, 11c, l ld, ll in Driving direction 2 too.
- the rail elements I Ia, IIb, 11c, lld, llle free thermally expand in the direction of travel 2, without resulting in a bracing by mounting on the shaft wall 5.
- the elevator car 7 is driven by means of a linear motor.
- the linear motor 19 comprises primary parts 21, which are arranged on the rail elements IIa, IIb, 11c, lld, l le and a secondary part 23 which is connected to the car.
- the rail elements IIa, Ib, 11c, lld, lle thus simultaneously form drive modules.
- FIG. 2 shows a rail element 11 with a fixed bearing 15 and a movable bearing 17.
- the fixed bearing 15 comprises a first holder 25, which is on the one hand firmly connected to the rail element 11 and on the other hand fixed to the shaft wall 5 is connectable (screwed, for example).
- the movable bearing 17 comprises a second holder 27 which is fixedly connected to the rail element 11.
- the second holder 27 is positively received by a socket 29, in which the second holder 27 is movable only in one direction (perpendicular to the plane). This direction corresponds to the mounting of the direction in which the rail member 11 can expand thermally freely.
- the version 29 is in turn firmly connected to the shaft wall 5.
- Figure 3 shows an embodiment of a guide rail with two different forms of the invention. Shown are a section of a guide rail section 13. Shown are two rail elements I Ia, I Ib, which together form the guide rail section 13. The rail elements I Ia and I Ib have a distance to each other, so that the rail elements I Ia and I Ib can expand thermally in the direction of travel 2 free.
- the guide rail section 13 has a plurality of functional raceways 31a, 31b and 31c.
- the functional raceways 31a and 31b are each a rolling raceway 31a, 31b for a guide roller of an elevator car 7.
- the functional raceway 31c is a brake raceway 31c for a jaw brake of an elevator car 7. It is typical in elevator cars with linear drive To arrange brake between the elevator car 7 and guide rail 9 and to generate the braking force by a jaw brake of the elevator car 7 acts on the guide rail 9.
- the distance between the adjacent rail elements I Ia and I Ib normally leads to an interruption of the functional raceways 31a, 31b and 31c.
- the rail elements I Ia and I Ib in the region of the functional raceways 31a, 31b and 31c are designed to be suitable.
- the rail element 11a has two pins 33 which engage in associated blind holes 35 of the rail element 11b.
- the boundaries of the two rail elements I Ia and I Ib thus have a complementary Course.
- the pins 33 push deeper into the blind holes 35.
- An arbitrary, perpendicular to the direction of travel 2 cross section of the guide rail portion in the functional career 31c extends either through the rail element I Ia that also includes the pins 33, or by the rail member I Ib.
- the two rail elements I Ia and I Ib are in a sense connected in the region of the brake raceway 31c.
- a jaw brake acts in the region of the braking track 31c on the guide rail 9. This leads to a certain deformation of the guide rail 9 in this area.
- the braking distance of the elevator car 7 extends over a plurality of rail elements I Ia, I Ib.
- the braking distance of a descending elevator car 7 could begin in the region of the rail element Ib and end in the region of the rail element 11a.
- the jaw brake acts only on the rail element I Ib and not on the rail element I Ia it would therefore come without the pins 33 to a deformation of the rail element I Ib but not of the rail element I Ia.
- a uniform braking process would not be ensured, since an offset of the rail elements I Ia and I Ib in the region of the brake raceway 31 is created by the braking effect.
- the pins 33 which engage in the blind holes 35, cause the deformation is also transferred to the rail member I Ia, although the jaw brake acts only on the rail member I Ib. It is thus ensured a uniform steady course of the brake track.
- a notch 37 is provided adjacent to the brake track 31c in the adjacent rail elements 11a, 11b to reduce the rigidity of the two rail elements 11a, 11b in the region of the brake raceway 31c.
- FIG. 3 Also shown in FIG. 3 is a second embodiment of the invention. Both in the area of the rolling track 31a and in the area of the rolling track 31b, a transition element 39 is arranged.
- the transition element 39 simultaneously allows thermal expansion of the rail element I Ia in the direction of the adjacent rail element Ib as well as trouble-free rolling of guide rollers of an elevator car 7 along the rolling tracks 31a and 31b.
- the exact structure of the transition element 39 is explained below with reference to Figures 4 and 5.
- FIG. 4 shows a detailed representation of the transition element in a built-in state.
- a configuration is shown, in which still a significant distance is present between a first rail element I Ia and a second rail element I Ib.
- a thermal expansion of the first rail element 11a has already taken place in the direction of the adjacent second rail element 1b.
- the distance between the rail elements I Ia and I Ib is reduced.
- the first rail element I Ia and the second rail element I Ib have opposing boundaries which have a complementary course to one another.
- the first rail element 11a has comb-shaped formations 41a in the area of the rolling raceway 31a.
- the second rail element Ib also has comb-shaped formations 41b.
- the two comb-shaped formations 41a and 41b are offset from each other and engage each other, so that there is the complementary course of the boundaries.
- the comb-shaped formations 41a and 41b slide into one another until the configuration shown in the right-hand area of FIG. 4 results.
- the rail elements I Ia and I Ib are in the configuration according to the left portion of Figure 4 or according to the right part of Figure 4 or in an intermediate state, runs any, perpendicular to the direction of travel 2, cross section of the guide rail portion in the area the rolling raceway 31a through at least one of the two adjacent rail elements I Ia, I Ib.
- the two rail elements I Ia and I Ib are connected to a certain extent in the region of the rolling track 31a, without resulting in a gap in which the rolling guide roller could lose contact with the rail elements I Ia and I Ib.
- the boundary is shaped such that the arbitrary, perpendicular to the direction of travel 2, cross section in the region of the rolling track 31a has an extension which corresponds to at least 20% of the extent of the rolling track 31a perpendicular to the direction of travel 2.
- the expansion is nearly 50% for each cross section.
- the cross section along the line 43 intersects the first rail element 11a in the region of the comb-shaped formations 41a.
- FIG. 5 shows a detailed representation of the transition element 39 in the uninstalled state.
- the transition element 39 comprises a first bolt 45, on which a plurality of first plates 47 are lined up.
- the first plates 47 have a bore 49 through which the first bolt 45 extends.
- the first plates 47 are rotatable about the first pin 45.
- the first bolt 45 and the first plates 47 are components of the first rail element 11a (see FIG. 4).
- the first plates 47 form the comb-shaped formations 41a of the first rail element I Ia.
- the transition element 39 comprises a second pin 51, on which a plurality of second plates 53 are lined up.
- the second plates 53 have a bore 55 through which the second pin 51 extends.
- the second plates 53 are rotatable about the second pin 51.
- the second bolt 51 and the second plates 53 are components of the second rail element Ib (see FIG. 4).
- the second plates 53 form the comb-shaped formations 41b of the second rail element Ib.
- first plates 47 Opposite the bore 49, the first plates 47 have a slot 57 through which the second pin 51 extends. Accordingly, the second plates 53 a slot 59 opposite to the bore 55, through which the first bolt 45 extends. Accordingly, in each case alternately first plates 47 and second plates 53 are lined up on both bolts 45, 51, with a respective bore 49, 55 and a slot 57, 59 alternating.
- This structure allows the distance between the first bolts 45 and the second bolt 51 to be variable. In the illustration shown, the two bolts 45, 51 have their minimum distance. Increasing the distance between the two bolts 45, 51, so the first pin 45 shifts within the slots 59 while the second pin 51 shifts within the slots 57. The distance between the two bolts 45,51 can therefore be increased so far until the bolts 45,51 each at the end of the slots 57, 59 are located.
- the first plates 47 and the second plates 53 in the installed state are oriented and arranged so that the narrow sides 61 of the first plates 47 and the narrow sides 63 of the second plates 53 extend along the functional track 31 and a Form part of the functional career 31a.
- the narrow sides 61 and 63 are substantially flush with the remaining functional raceway 31a, so that there is a flat running surface for the guide rollers of the elevator car 7.
- the rolling raceway 31a on the first rail element has a slightly greater distance to the elevator car than the rolling raceway 31a on the second rail element.
- the first plates 47 are rotatably mounted on the first pin 45 and on the second pin 51.
- the second plates 53 are rotatably mounted on the first pin 45 and on the second pin 51.
- FIG. 6 schematically shows two further developments of the invention.
- two rail elements I Ia and I Ib are shown with a functional track 31a in a direction of travel 2. Between the two adjacent rail elements I Ia and I Ib is a distance, so that the rail elements I Ia and I Ib can freely expand in the direction of travel 2.
- the adjacent rail elements I Ia and I Ib have opposite boundaries in the area of the functional raceway 31, which have such a complementary course that any cross-section of the guide rail section perpendicular to the travel direction 2 in the region of the functional raceway 31 passes through at least one of the two adjacent rail elements I Ia and I Ib runs.
- the two rail elements I Ia and I Ib are so to speak shaped in the functional raceway so that no continuous gap perpendicular to the direction of travel 2 results.
- the guide roller can thus not lose contact with the rail elements I Ia and I Ib due to a gap.
- the boundary is shaped such that the arbitrary, perpendicular to the direction of travel 2, cross-section in the region of the functional track has an extension which corresponds to at least 20% of the extent of the functional track perpendicular to the direction of travel 2.
- the opposing boundaries have a stepped course, while in the right-hand representation, a straight course is present with an angle 67 to the direction of travel.
- the expansion is almost 75% for each cross section.
- the cross-section along the line 43 intersects the first rail member 11a and the second rail member 1b so that approximately half the width of the functional raceway 31 is formed by the first rail member and approximately one-fourth of the functional raceway width by the second rail member rail element. Overall, this results in an expansion of about 75% of the total width of the functional career.
- the angle 67 which is less than 70 °, ensures that any cross-section perpendicular to the direction of travel 2 has an extent in the region of the functional track 31 that is at least 20% of the extent of the functional track 31 perpendicular to the direction of travel 2 corresponds.
- Both embodiments shown have the additional advantage that the two rail elements I Ia and I Ib can be pivoted against each other.
- the first rail element I Ia can be pivoted about an axis of rotation 69 in a direction 71 relative to the second rail element I Ib.
- a pivoting of rail elements to each other is helpful if the direction of travel of an elevator car is to be changed from vertical travel in a horizontal travel. In certain variants for realizing such a change in direction, this can be made possible for example by pivoting rail elements. An example of this can be found in JPH0648672.
- Figure 7 shows a development of the embodiment, which is shown in the left portion of Figure 6.
- the area of the functional track is shown in three-dimensional representation.
- a distance is present between the two adjacent rail elements I Ia and I Ib so that the rail elements I Ia and I Ib can freely expand in the direction of travel 2.
- the opposite boundaries have a step-shaped course.
- the opposing boundaries also have a chamfer 73.
- a corresponding curvature can also be provided. It is only important that a funnel-shaped course results along the functional track. This has the advantage that the butt edges are reduced in a non-ideal adjustment of the rail elements after a pivoting operation. For example, there may be some misalignment between the adjacent rail elements or an inclination between rail elements.
- FIGS. 8, 9 and 10 show a further embodiment of a guide rail according to the invention.
- FIG. 8 shows a three-dimensional representation of a guide rail section 13. Shown are two rail elements 11a, 11b, which together form the guide rail section 13.
- the rail elements I Ia and I Ib have a distance from each other, so that the rail elements I Ia and I Ib can expand thermally in the direction of travel 2 free.
- the guide rail section 13 has a functional raceway 31a.
- the functional raceway 31a is a rolling raceway for a guide roller of an elevator car. In the present case, the same track is also used as a brake track.
- the guide rail in the present case has a T-shaped cross-section
- a wedge-shaped transition piece 75 is arranged between the two adjacent rail elements 11a and 11b.
- Figures 9 and 10 respectively show enlarged views of the area with the wedge-shaped transition piece 75 in two different states. In the right-hand part of FIGS. 9 and 10, a three-dimensional view of this area is shown, while in the left-hand area of FIGS. 9 and 10 a lateral frontal view is shown.
- FIG. 9 shows the guide rail section 13 in a first state with a first temperature.
- FIG. 10 shows the same guide rail section 13 in a second state, for example after a temperature increase. Alternatively, this state can also be achieved by a building setting, by the adjacent rail elements to move towards each other.
- the operation of this embodiment will be explained with reference to FIGS. 8, 9 and 10.
- the two adjacent rail elements I Ia and I Ib have opposite edges which are rectilinear and at an angle to each other. This angle corresponds to the wedge angle 79 of the wedge-shaped transition piece 75.
- the wedge-shaped transition piece 75 in the region of the functional raceway 31 fits exactly into the intermediate space between the adjacent rail elements I Ia and I Ib.
- the functional race 31a extends over the wedge-shaped transition piece 75.
- FIG. 9 shows the guide rail section 13 in a cold state
- the same guide rail section 13 after heating is shown in FIG. (Respectively before the building setting and after the building setting)
- the two adjacent rail elements I Ia and I Ib have each thermally expanded in the direction of travel, so that the distance between the two rail elements I Ia and I Ib has reduced (transition from Figure 9 to Figure 10th ).
- both rail elements I Ia and I Ib each have a force parallel to the direction of travel on the wedge-shaped transition piece 75 exerted. This force has meant that the wedge-shaped transition piece 75 in the heated state ( Figure 10) is disengaged against the wedge direction 77.
- the wedge direction 77 is the direction toward the pointed end of the wedge-shaped transition piece 75, which extends along the bisector of the wedge angle 79 of the wedge-shaped transition piece 75.
- the compression springs 81a and 81b extend between the blunt end of the wedge-shaped transition pieces 75 and a holding device 83.
- the wedge-shaped transition piece 75 is disengaged against the spring force of the compression springs 81a, 81b.
- the transition piece 75 is then re-engaged by means of the spring force of the compression springs 81a, 81b.
- the compression springs 81a and 81b are configured and oriented such that the spring force runs parallel to the wedge direction 77.
- the guide 85a comprises a groove 87a on the rail element 11a, into which a spring 89a engages.
- the spring 89a is arranged on the wedge-shaped transition piece 75.
- a guide 85b is provided between the transition piece 77a and the rail element Ib.
- the guide 85b comprises a groove 87b on the rail element Ib, into which a spring 89b engages.
- the spring 89b is arranged on the transition piece 77.
- the two guides 85a, 85b ensure that the wedge-shaped transition piece 75 performs a well-defined translational movement. In each position of the wedge-shaped transition piece 75 thus a uniform and continuous functional track 31a is ensured. This is especially true in the region of the transition between the rail elements I Ia and I Ib and the wedge-shaped transition element 75th LIST OF REFERENCE NUMBERS
