Definitions
- the invention relates to an elevator system with the features of the preamble of claim 1.
- EP 2219985 B1 describes an elevator system with two elevator cars that can be displaced in the vertical direction in an elevator shaft, a self-contained suspension element guided around a lower deflecting roller and an upper deflecting roller, one of the
- the suspension element has several coupling elements, which can be designed, for example, as holes or cams.
- a coupling device of an elevator car can be coupled to and uncoupled from a coupling element, whereby a drive connection between the respective elevator car and the suspension element can be established and released.
- An elevator car coupled to a suspension element can thus be displaced in the first elevator shaft by means of the suspension element that can be driven by the respective drive machine.
- the elevator cabs are only shifted in one direction in the named elevator shaft, that is to say only upwards or only downwards.
- the elevator system has a further elevator shaft in order to be able to realize a circulating operation of the elevator cabins.
- the elevator cars can be shifted horizontally between the two elevator shafts by means of a transfer device. In operation of the
- Elevator system an elevator car is coupled at a lower or an upper end position via its coupling device and a coupling element to a suspension element and is shifted upwards or downwards via the suspension element by the associated drive machine until it has reached the upper or lower end position. There the elevator car is uncoupled from the suspension element and is transferred horizontally into the other by a transfer device in the elevator shaft for the other direction of displacement
- the described coupling elements of the suspension elements can, as described above, be connected to an elevator car via a coupling device.
- This Coupling elements are referred to below as connected coupling elements.
- the coupling elements cannot be coupled to an elevator car.
- These coupling elements are hereinafter referred to as free
- Coupling elements relocated in the elevator shaft.
- the suspension elements can vibrate.
- the connected coupling elements are prevented from swinging by their coupling with an elevator car. Without suitable countermeasures, the free coupling elements would join the vibrations of the suspension element. This could lead to a free coupling element hitting an elevator car when passing it, or a free
- the coupling element strikes the elevator shaft. Such an attack could on the one hand lead to an audible shock and on the other hand could damage the
- the elevator system has an elevator car that can be displaced in an elevator shaft, a suspension element running in the elevator shaft, a drive machine assigned to the suspension element and a controllable coupling device arranged on the elevator car.
- the suspension element has a coupling element to which the coupling device can be coupled and uncoupled, whereby a drive connection between the elevator car and the suspension element can be established and released.
- the coupled elevator car can be displaced in the elevator shaft by means of the suspension element that can be driven by the drive machine.
- the elevator system has a guide system for guiding the
- the guide system has a fixed guide opposite the elevator shaft and one with the Coupling element connected via a connection, runner guided along the guide.
- the connection between the coupling element and the rotor is designed in such a way that a relative movement between the rotor and the coupling element is possible.
- the connection mentioned can thus also be referred to as a flexible connection.
- the mentioned guide system advantageously prevents a free coupling element from hitting an elevator car and elevator shaft during displacement in the elevator shaft and thus enables particularly convenient operation of the elevator system.
- Connected coupling elements are fixed to one
- Elevator cabin coupled and thus make all movements of the corresponding elevator cabin with.
- elevator cars are usually guided along car guide rails which can be aligned with respect to the guide of the coupling element. Nevertheless, the corresponding elevator car can be shifted and / or tilted with respect to the guidance of the coupling element. Such shifts and / or
- Tilting can be caused, for example, by an uneven load distribution within the cabin.
- the flexible connection of the coupling element to the runner according to the invention enables the described displacement and / or tilting of the elevator car and thus of the coupling element with respect to the guidance of the guide system of the coupling element to be compensated. Since the
- the elevator car can exert great forces on the coupling element due to its mass during the displacement and / or tilting described, damage to the guide system of the coupling element could occur without the compensation described.
- the runner and / or the guide could be damaged, which can lead to failure of the elevator system.
- the flexible connection of the rotor to the coupling element according to the invention prevents such damage to the guide system of the coupling element and thus failure of the elevator system. In addition to particularly convenient, particularly reliable operation of the elevator system is thus made possible.
- the guide in the elevator shaft is not movable.
- the guide can for example be designed as a guide rail which is fixed, for example screwed, to a shaft wall of the elevator shaft. It is also possible that the guide is formed by the shaft wall itself.
- the shaft wall can have a special guide surface, for example.
- the runner can also be referred to as a trolley.
- the runner can, for example, have one or more guide rollers that roll on the guide and are thus guided by it. It is also possible that the runner has a sliding surface on which the guide slides along and is thus guided by it.
- connection via which the rotor is connected to the coupling element, can be designed, for example, as an axis in the form of a pin, which is movable at least in one direction relative to the coupling element.
- the aforementioned relative movement between the rotor and the coupling element has in particular at least one horizontal component. It is also particularly limited.
- the elevator system has more than one elevator car, that is to say for example two to eight elevator cars, which are basically constructed identically and all have a coupling device.
- the elevator system has in particular more than one elevator shaft, especially two elevator shafts, between which the
- Elevator cabins can be moved by means of transfer devices.
- a transfer station is arranged at both ends of the elevator shafts, so that continuous operation of the elevator cars is possible.
- the elevator cars are only shifted from bottom to top in a first elevator shaft and only from top to bottom in a second elevator shaft.
- the elevator cars are moved into the other elevator shaft by means of a transfer station.
- the elevator shaft or the elevator shafts are arranged in or on a building and run mainly in the vertical direction, so that the elevator cars are mainly shifted vertically when they are moved in the elevator shaft.
- the suspension element is in particular self-contained, that is to say, for example, embodied in an annular manner. It can also be called endless. However, this does not necessarily mean that it is designed as a homogeneous ring or only consists of one piece.
- the suspension element is in particular around a lower and an upper deflection roller out, wherein at least one pulley serves as a drive roller or drive pulley, via which the support means can be driven by the drive machine assigned to it.
- the deflection rollers have an effective diameter of less than 100 mm. Such small effective diameter of a serving as a traction sheave
- Deflection pulleys enable a gearless drive of the suspension element, which requires little installation space.
- a tensioning device can be arranged on the suspension element, with which, on the one hand, the necessary suspension element pretension is generated and, on the other hand, deviations in the original length of the self-contained suspension element as well as operational plastic changes in the suspension element are compensated.
- the necessary clamping forces can be generated with tension weights, gas springs or metal springs, for example.
- the drive machine is designed in particular as an electric motor that is controlled by an elevator control.
- the elevator control controls the entire operation of the elevator system, i.e. it controls all controllable components of the elevator system and is connected to switches and sensors of the elevator system.
- Elevator control can be designed as a single central elevator control or consist of several decentralized controls that are responsible for sub-tasks.
- the coupling devices arranged on the elevator car or cabins are arranged in particular on a floor or a roof of the elevator cars and are controlled by the elevator control mentioned above.
- Coupling device takes place in particular in a form-fitting manner, with a
- the coupling element has, in particular, a mainly horizontally oriented recess into which, for example, an extendable and retractable bolt of the coupling device can dip in one actuation direction.
- the coupling device is in this case in its coupled position when the bolt of the coupling device in the recess of the
- Coupling element is immersed and in its uncoupled position when the bolt is not immersed in the recess.
- a positive or frictional connection between the elevator car and the suspension element can thus be established via the coupling device and the coupling element so that when the propellant is displaced or moved, the elevator car is also displaced. This is a drive connection between the
- Elevator cabin and the suspension element and thus ultimately between the elevator cabin and the drive machine assigned to the suspension element can be produced and also released again.
- the coupling devices are controlled in particular in such a way that only one elevator car is coupled to a (single) suspension element at least during the displacement of an elevator car.
- only one (single) elevator car is therefore always displaced in the shaft by a (single) suspension element.
- a coupling element of a suspension element is designed in particular as a connecting element which connects two free ends of the suspension element to one another.
- the use of a self-contained suspension element makes it possible to dispense with a counterweight which has to be guided past the elevator car, which enables the elevator shaft to have a small cross section.
- the coupling element designed in this way fulfills a double function. It serves, on the one hand, to couple the elevator car to the suspension element and, on the other hand, to make the closed suspension element simple and inexpensive.
- the coupling element particularly fulfills the function of a so-called
- a self-contained suspension element can thus be produced very simply, inexpensively and safely from an originally open, elongated suspension element by connecting the two free ends to the coupling element.
- the coupling element can, for example, have two suspension element end connections connected to one another, which can be designed, for example, according to EP 1634842 A2.
- the two support means end connections can for example be connected via an intermediate piece with which they can be screwed or welded, for example.
- the coupling element can also have a one-piece housing.
- the guidance system runs along a shaft wall of the elevator shaft.
- the mentioned connection between the coupling element and the rotor is designed so that a first relative movement between the rotor and the coupling element with at least one component in the direction of the mentioned
- Said component of the direction runs in particular mainly perpendicular to the shaft wall and thus mainly horizontally.
- the mentioned relative movement runs in particular only towards the shaft wall and away from the shaft wall and thus in particular only perpendicular to the shaft wall.
- it can also have a component that is aligned along the shaft wall, that is to say, overall, run obliquely to the shaft wall or along a circular path.
- the guide is designed in particular as a guide rail that is attached to the
- the mentioned direction of the component of the relative movement thus also runs in the direction of the guide rail and away from the guide rail.
- the statements relating to the alignment of the relative movement with respect to the shaft wall thus apply analogously to an alignment of the relative movement with respect to the guide rail.
- the relative movement also runs in particular in the actuation direction mentioned above, in which a bolt of the
- Coupling device for coupling to a coupling element can be extended and retracted.
- Elevator shaft can be understood in the horizontal direction.
- a shaft wall is designed in particular as a solid wall, for example made of concrete.
- a shaft wall is only formed from a plurality of cross members, to which, for example, car guide rails can be fixed. This can occur in particular if several elevator shafts are arranged next to one another and the individual elevator shafts are separated from one another by cross members.
- connection between the coupling element and runner has a pin, which is coupled to the runner and in a recess in the coupling element in the direction of the shaft wall and from the shaft wall is arranged displaceably away.
- the pin can be fixed to the runner, for example screwed on. It is also possible for the runner to act as one
- Guide roller is performed, which is rotatably arranged on the pin.
- the runner can also have a lever which is pivotably arranged on the pin.
- the recess is in particular as a
- connection has a first spring arrangement which is designed and arranged in such a way that it can apply a force to the runner in the direction of the first relative movement. This can occur
- Relative movements between the rotor and coupling element are cushioned in the direction of the first relative movement. This enables a particularly calm guidance of the runner.
- the first spring arrangement in particular has a first spring which presses the runner away from the coupling element. This means that the runner can bump into the
- the first spring arrangement also has, in particular, a second spring which pulls the runner towards the coupling element. Relative movements of the rotor away from the coupling element can thus also be cushioned.
- a rest position of the rotor can be set in the direction of the first relative movement, which the rotor then assumes when no other forces are acting on it.
- the guide runs along a shaft wall of the elevator shaft.
- the connection between the coupling element and the runner is designed in such a way that a second relative movement between the runner and the coupling element along said shaft wall with at least one horizontal component is possible. Enabling a second relative movement between the runner and the coupling element enables particularly comfortable and reliable operation of the elevator system.
- Said relative movement can in particular run horizontally and thus have only one horizontal component. It then runs mainly parallel to the shaft wall mentioned. However, it can also have a vertical component or run along a circular path.
- connection between the coupling element and runner is designed in particular so that a first relative movement between runner and coupling element with at least one component in the direction of the shaft wall and away from the shaft wall and, in addition, a second relative movement between the rotor and coupling element along the shaft wall with at least one horizontal component are possible.
- a first relative movement between runner and coupling element with at least one component in the direction of the shaft wall and away from the shaft wall and, in addition, a second relative movement between the rotor and coupling element along the shaft wall with at least one horizontal component are possible.
- the guide guides the runner in the direction of the first relative movement and in the direction of the second relative movement between the runner and the coupling element. This enables particularly reliable guidance of the rotor and thus of the coupling element. This leads to particularly convenient operation of the elevator system. Guiding the runner in the direction of the first and second relative movement should be understood to mean that the runner cannot be displaced or can only be displaced to a very limited extent with respect to the guide in the direction of the first and second relative movement. In the case of a vertical guide, the runner can mainly only be displaced vertically.
- said recess which at least partially receives the above-mentioned pin, is on a swivel arm of the
- connection has a second spring arrangement which is designed and arranged such that it can exert a force on the rotor in the direction of the second relative movement. This can occur
- Relative movements between the rotor and coupling element are cushioned in the direction of the second relative movement. This enables a particularly calm guidance of the runner.
- the second spring arrangement has in particular a third and a fourth spring which act in opposition to one another.
- a rest position of the rotor can be set in the direction of the second relative movement, which the rotor then assumes when no other forces are acting on it.
- the guide has a side cheek and the runner has a guide roller, the guide roller being guided on an inside of the side cheek of the guide.
- a side cheek should be understood to mean a section of the guide which projects away from the shaft wall into the elevator shaft.
- the guide has, in particular, a first side cheek and an opposite second side cheek
- the runner has a first guide roller and a second guide roller.
- the first guide roller is guided on the inside of the first side wall of the guide and the second guide roller on the inside of the second side wall of the guide. Guiding by means of two guide rollers enables particularly good guidance of the coupling element and thus particularly convenient operation of the elevator system.
- the first guide roller is mounted on a first roller axle and the second guide roller on a second roller axle.
- Roller axles are arranged on a lever of the rotor that can be pivoted about a lever axle, the two roller axles in particular on the lever axle opposite sides of the lever are arranged. With that you can through a
- the lever axis of the pivotable lever of the rotor is at least partially formed by the above-described pin of the connection between the coupling element and the rotor.
- the pen thus has a double function, which makes it easy and inexpensive to connect the rotor to the
- Coupling element allows.
- the third spring arrangement has a fifth spring and, in particular, a sixth spring, which are tensioned between the lever of the rotor and the coupling element in such a way that they press the guide rollers against the inside of the side walls of the guide. If there is a sixth spring, it works in the same direction as the fifth spring.
- the inner sides of the side walls of the guide have a concave contour and the guide rollers of the runner have a corresponding convex profile.
- Elevator system allows.
- the side cheeks enable simultaneous guidance in the said first direction and the said second direction of the relative movement between the rotor and the coupling element. This enables very precise guidance of the coupling element and thus particularly convenient operation of the elevator system in a simple and cost-effective manner.

- FIG. 5 shows a section through a coupling element including a guide system
- FIG. 7 shows a view of a runner in a guide of the guide system
- an elevator system 10 has a first elevator shaft 12 in which a first elevator car 14 and a second elevator car 16 are arranged.
- the first elevator car 14 is located at a lower end position 18, which is a position of
- the second elevator car 16 is located at an upper end position 22, which corresponds to a position of the elevator car 16 on an uppermost floor of the building 20. Between the lower end position 18 and the upper end position 22 there are a plurality of floors that are not shown in FIG. 1.
- the elevator system 10 has a car guide rail 24 running in the vertical direction, on which the elevator cars 14, 16 during a displacement in the Elevator shaft 12 are guided. To move the elevator cars 14, 16 in the elevator shaft 12, the elevator system 10 has a total of eight self-contained suspension elements 26, of which four suspension elements 26 are shown in FIG. 1.
- the support means 26 are designed as belts and are each guided around a lower deflection roller 28 and an upper deflection roller 30.
- the two deflection rollers 28, 30 of a suspension element 26 are arranged vertically one above the other, so that the suspension elements 26 run vertically between the deflection rollers 28, 30.
- the deflection rollers 28, 30 in particular have an effective diameter of less than 100 mm.
- the lower pulleys 28 are below the first
- Elevator car 14 is arranged and each connected to a tension weight 32.
- the tension weight 32 acts as a tensioning device with which on the one hand the
- the necessary suspension element pretension is generated and, on the other hand, deviations in the original length of the self-contained suspension element 26 and operational plastic changes in length of the suspension element 26 are compensated.
- the upper deflection rollers 30 are arranged above the second elevator car 16 and each serve as a drive pulley for a drive machine designed as an electric motor.
- Each support means 26 is assigned a drive machine 34 by means of which the support means 26 can be driven and displaced.
- the drive machines 34 are controlled by a control device in the form of an elevator controller 36, which controls all of the actuators of the elevator system 10.
- Each suspension element 26 consists of two suspension element parts 38, 40, the free ends 42 of which are connected by means of two coupling elements 44, shown enlarged in FIG. 2.
- the coupling element 44 consists of two support means end connections 46 which are oriented in opposite directions and which are connected to a connection element 50 having a recess 48.
- the suspension element end connections 46 can, for example, correspond to those described in EP 1634842 A2
- An extendable bolt 60 of a coupling device 58 arranged on an elevator car 14, 16 can dip into the recess 48, with the result that the coupling device 58 is coupled to the coupling element 44. By pulling the bolt 60 out of the recess 48, the coupling device 58 can be uncoupled from the coupling element 44.
- the Coupling devices 58 are arranged on a floor 51 of the elevator cars 14, 16 and are described in more detail in connection with FIG. 4.
- a coupling element 44, to which a coupling device 58 has been coupled, has a filled square in the figures. In FIG. 1, the second elevator car 16 is thus via a coupling element 44 with the one on the far left in FIG.
- the coupling devices prefferably be arranged on the roof of an elevator car.
- the positions of the coupling elements on the suspension elements must then be adapted accordingly.
- Drive machine 34 is driven or displaced.
- the second elevator car 16 can thus be displaced in the elevator shaft 12. Since the first elevator car 14 in FIG. 1 is not coupled to any suspension element 26, in the state of FIG. 1 it is not possible to move the first elevator car 14 in the elevator shaft 12.
- FIG. 3 shows a view from above of the first elevator shaft 12 with a total of eight drive machines 34.
- the drive machines 34 are each drive-connected to a drive pulley in the form of a deflection roller 30, over which a suspension element 26 runs.
- the reference symbols are shown only once in FIG. 3.
- Four drive machines 34 are arranged on opposite sides of the elevator car 16, with two drive machines 34 being arranged on each of the opposite sides of the elevator car 16 on different sides of the running car guide rail 24.
- Drive axles 52 of the drive machines 34 run parallel to one another, with one drive machine in each case 34 is arranged on one side of the elevator car 16 coaxially to a drive machine 34 on the other side of the elevator car 16.
- a car door (not shown) of the elevator car 16 is located on one or both free sides 54 of the elevator car 16, on which no drive machines 34 are arranged.
- the elevator control 36 (see FIG. 1) always controls two drive machines 34 on opposite sides identically or synchronously, so that the support means 26 assigned to them also move or are displaced synchronously.
- Two drive machines 34 are always controlled in the same way, which are arranged diagonally with respect to a center of gravity 56 of the elevator car, so for example in FIG. 3 the upper, far left drive machine 34 and the lower, far right drive machine 34 four elevator cars 14, 16 can be moved simultaneously and independently of one another in the first elevator shaft 12.
- Fig. 4 is a view from below of the elevator car 16 with two
- Coupling devices 58 for coupling to coupling elements 44 of support means 26 are shown.
- the coupling devices 58 are each arranged opposite the drive machines 34, not shown in FIG. 4, and thus opposite the coupling elements 44 of the support means 26.
- Each coupling device 58 has a bolt 60 which can be extended and retracted in an actuation direction 62 which is oriented in the direction of the coupling elements 44.
- the coupling device 58 has an actuating actuator 64, which can be designed, for example, as an electric motor.
- the bolt 60 together with the actuation actuator 64 can be moved horizontally and perpendicular to the actuation direction 62 along a rail 66 by means of a positioning actuator 68, which is also designed as an electric motor, for example.
- the bolt 60 is first correctly positioned with respect to the corresponding coupling element 44. Then the bolt 60 is extended, whereby the bolt 60 into the recess 48 of the
- Coupling element 44 is immersed. This creates a positive connection between the coupling device 58 and the coupling element 44 and thus between the Elevator car 16 and the suspension means 26 produced. If this form-fitting
- the elevator car 16 is always coupled to two support means 26, which with respect to the center of gravity 56 of the
- Elevator car are arranged diagonally. This takes place in that the elevator car 16 is always coupled to coupling elements 44 which are arranged diagonally with respect to the center of gravity 56 of the elevator car 16.
- the bolts of the coupling devices cannot be moved.
- the coupling devices have separate bolts for each coupling element, or a coupling device is assigned to exactly one coupling element and thus to exactly one support means.
- the drive machines and thus the suspension means can also be arranged on a side of the elevator car opposite the car door and thus shaft doors.
- an elevator car has, in particular, only one coupling device, so that an elevator car is only coupled to one suspension element for displacement in the elevator shaft.
- the elevator system 10 has a second elevator shaft, not shown, which is arranged parallel to the first elevator shaft 12.
- the second elevator shaft is designed analogously to the first elevator shaft 12.
- the relocation of the elevator cars 14, 16 in the second elevator shaft is implemented analogously to the relocation in the first elevator shaft 12. In the first elevator shaft 12, the elevator cars 14, 16 are only shifted upwards and in the second elevator shaft only downwards.
- the elevator system 10 has two not shown
- Transfer devices by means of which the elevator cars 14, 16 can be moved from the first to the second or from the second to the first elevator shaft.
- the transfer devices can in particular correspond to the transfer devices in Be designed in the form of horizontal displacement units of EP 2219985 B1.
- a coupling element 46 is guided by a guide system 80, which is explained in connection with FIGS. 5-7.
- a coupling element 46 is connected to a runner 82 of the guide 80 via a connection 81.
- the runner 82 is guided in a guide in the form of a so-called C-rail 83.
- the C-rail 83 is screwed to a shaft wall 84 of the elevator shaft 12, not shown in FIG. 5, and is thus fixed. It thus runs along the shaft wall 84 and is stationary with respect to the elevator shaft 12.
- the runner 82 has a first, upper guide roller 85 and a second, lower guide roller 86, which are arranged on a lever 87 pivotable about a lever axis 88.
- the first guide roller 85 is mounted on a first roller axle 89 and the second guide roller 86 on a second roller axle 90.
- the two roller axles 89, 90 are arranged on opposite sides of the lever 87 with respect to the lever axle 88.
- the C-rail 83 has two opposite one another
- the rotor 82 has a third spring arrangement 95 with an upper, fifth spring 96 (only visible in FIG. 6) and a lower, sixth spring 79 (only visible in FIG. 5)
- the springs 96, 79 are tensioned between the lever 87 and the coupling element 46 such that the guide rollers 85, 86 are pressed against the inner sides 92 of the side cheeks 91 of the C-rail 83.
- the spring arrangement 95 is shown more clearly in FIG.
- connection 81 via which the rotor 82 is connected to the coupling element 46 is, has a pin 97, which also forms the lever axis 88 of the pivotable lever 87 of the rotor 82.
- a part of the pin 97 opposite the rotor 82 protrudes through a recess in the form of a through opening 98 through a swivel arm 99 of the coupling element 46
- the pin 97 can be displaced to a limited extent in the recess 98 in the direction of the shaft wall 84 and away from the shaft wall 84. He can therefore in the above first direction 93 are shifted. A first relative movement between the rotor 82 and the coupling element 46 in the first direction 93 is thus possible.
- a first spring 101 in the form of a helical spring is arranged around the pin 97 between the lever 87 of the rotor 82 and the swivel arm 99.
- the first spring 101 presses the lever 87 and thus the runner 82 in the direction of the shaft wall 84.
- a second spring 102 in the form of a helical spring is arranged around the pin 97 between the pivot arm 99 and the cap 100 of the pin 97.
- the second spring 102 presses the cap 100 of the pin 97 and thus the lever 87 and the runner 82 away from the shaft wall 84.
- the first spring 101 and the second spring 102 thus form a first spring arrangement 103 of the connection 81.
- the pivot arm 99 having the through opening 98 can be pivoted about a pivot axis 104 which runs parallel to the through opening 98 and thus to the pin 97.
- the swivel arm 99 can thus execute a swivel movement to a limited extent along a circular path about the named swivel axis 104 and thus along the shaft wall 84.
- the possible movement of the swivel arm 99 thus has a horizontal component as well as a vertical one.
- the pivot arm 99 is pivoted, the through opening 98 and thus the pin 97 are also pivoted. With the pin 97, the lever 87 of the rotor 82 is also pivoted relative to the pivot axis 104 and thus relative to the coupling element 46.
- the pivot arm 99 is pivoted about the pivot axis 104, the rotor 82 thus guides a second one
- a second spring arrangement 106 which is only shown in FIG. 7, acts on the swivel arm 99.
- the spring assembly 106 has a third spring 107 which is between Swivel arm 99 and a vertically extending component 108 of the coupling element 46 is arranged such that it presses the swivel arm 99 to the left in FIG. 7.
- the spring assembly 106 also has a fourth spring 109 which is on the
- the third spring arrangement 95 is also clearly visible in FIG. 7.
- the upper, fifth spring 96 and the lower, sixth spring 79 are so tensioned between the outwardly projecting hook 110 of the lever 87 and the vertical component 108 of the coupling element 46 that the guide rollers 85, 86 against the inner sides 92 of the side cheeks 91 of the C- rail
