Description

Background of the invention

[0001] The invention relates to an operator's station, in particular for a mobile construction machine, comprising a base plate, a control device and a seat, wherein the seat is adjustable to improve visibility and entry and exit.

[0002] Operator stations are already known from the prior art and feature a control device carried on the machine for controlling the machine. Conventional operator stations also include a seat for the machine operator. Particularly in the case of machines with limited visibility, the seat is adjustable depending on the visibility conditions in order to monitor as wide an area around the machine as possible.

[0003] Patent specification DD 1 47 381 A1 discloses an operator's platform for a mobile compaction machine which can be swivelled completely to the right or left to improve visibility.

[0004] The operator platform must be mounted as a single unit on the rotating mechanism, which places high demands on the rigidity of the bearing design. Furthermore, while the operator platform can be rotated around its axis of rotation within a wide angular range, the control mechanism is positioned in such a way that the operator's line of sight is always directed towards the axis of rotation. Longitudinal or lateral adjustment is not possible. Additionally, the visibility is significantly limited by the weight of the operator platform, which precludes the use of a canopy or cab.

[0005] US 2003 / 0230920A1 describes a seating device to ensure rearward visibility for the driver when a vehicle is reversing. The seating device comprises a seat that is rotatably mounted to a vehicle body via a swivel mechanism. The seat has a mechanism that allows its rotational position relative to the vehicle body to be adjusted. In addition to the vehicle's accelerator pedal, a drive lever is provided by which the driver can manually operate a vehicle drive unit.

[0006] From DE 203 20 975 U1, a chair guide with a housing for receiving a chair mounting sleeve is known, the sleeve projecting into the housing through an elongated hole guide provided in a cover covering the housing and being movably mounted there. The chair mounting sleeve is detachably fastened in a movable carriage, wherein the lower end of the chair mounting sleeve is tapered downwards, in particular conical, and fits positively into a correspondingly designed opening in the carriage.

[0007] US Patent 6,679,349 B1 describes a forklift truck that allows a user to easily switch from one steering mechanism to another. The forklift truck includes a chassis with a frame mounted on a wheel assembly with axle and wheel components. The forklift truck also includes a drive assembly attached to the chassis. A pair of steering mechanisms are functionally located at opposite ends of the chassis. A pair of foot pedals are functionally located at opposite ends of the chassis. A lifting device is movable at one end of the chassis for lifting objects. A positionable seat is attached to the chassis and can be moved between the steering mechanisms.

[0008] US Patent 6,629,572 B2 discloses a drilling rig system with a human-machine interface located near the drilling rig to allow a single operator to have operational access to drilling rig processes from essentially one location. The workstation includes an adjustable base and an operator niche built onto the base, in which the operator is positioned to have an essentially unobstructed view of the drilling rig. At least one display unit is adjustable and connected to the base, featuring a touchscreen through which the operator can monitor and control the drilling rig's processes. An operator seat is positioned in the niche and is slidably connected to the base to allow operation while seated or standing.

[0009] CN 2 04 369 453 U describes a rail-mounted container gantry crane. It also features an adjustable seat that can move not only forwards, backwards, left and right, but also rotate, so that the operator does not have to stand up to observe the left, right and rear sides. Object of the invention

[0010] The object of the invention is to provide an operator's station that allows translational and rotational adjustment of the seating option with accompanying control means and can be easily installed in a driver's cab. Description of the invention

[0011] This problem is solved according to the invention by an operator station with the features according to claim 1.

[0012] The operator station is designed as an interchangeable assembly unit. This allows for particularly cost-effective production, independent of the machine being operated. The operator station comprises all functionally relevant components and therefore only needs to be attached to the machine via a mechanical and electrical connection.

[0013] The operator station comprises at least a base plate, a carriage, a seat console, a guide, and guiding elements. Further components are conceivable. This list is not exhaustive.

[0014] The base plate has a first and a second through-cut that connects the area below the base plate with the area above it. The base plate has a main extension direction along which the first and second through-cuts are formed. The main extension direction of the base plate is determined by the available installation space on the machine being operated. For example, the width of an available operator's cab can be a decisive factor in determining the length of the base plate in its main extension direction.

[0015] The first and second through-holes serve to accommodate guide elements that guide the carriage, located above the base plate and attached to the guide element, along a guide located below the base plate. The guidance is primarily linear. The guide elements extend through the first and second through-holes, with the end positions of the first and second through-holes defining the maximum travel distance of the guide elements within the first and second through-holes in the main direction of extension.

[0016] Therefore, only two through-holes in the base plate are required for the translational movement of the carriage. This reduces the ingress of dirt into the guide while ensuring stable guidance of the carriage, and makes manufacturing more cost-effective.

[0017] The first and second through-holes are particularly advantageously designed as linear slot openings. However, other designs for the first and second through-holes are also conceivable.

[0018] A rectangular base plate is particularly preferred, as this maximizes the extension of the first and second through-holes and thus the lateral adjustment. However, other base plate shapes are also possible. This can be especially advantageous with non-linear guides.

[0019] The carriage is positioned above the base plate and guided along a track located below the base plate. The carriage's load is transferred via the guide elements and the track itself. An air gap is formed between the carriage and the base plate, allowing the carriage to glide smoothly across the base plate.

[0020] The carriage also serves to transfer the translational movement through the guide to the components of the operator station arranged on the carriage.

[0021] A seat console can be detachably mounted above the carriage, particularly via screw connections. The seat console is multi-part and comprises a non-rotating console part attached to the carriage and a console part rotatable relative to the carriage and the non-rotating console part. This allows the seat console to be moved translationally via the carriage and rotated relative to the carriage via the rotatable console part.

[0022] In a preferred embodiment of the invention, a scraping device and / or sealing device, in particular a brush seal, is arranged in the first and / or second through-hole of the base plate. The scraping device can be arranged in and / or on the first and / or second through-hole on the top and / or bottom of the base plate. This allows a connection between the area below the base plate and the area above the base plate without the risk of dirt entering the guide.

[0023] Furthermore, other types of scraper devices are conceivable. Elastomer scraper devices are mentioned here as an example, but not an exhaustive list.

[0024] Furthermore, the carriage and / or the guide elements can have a scraper device that removes dirt from the base plate during the guided movement. This prevents dirt from entering through the first and / or second through-hole.

[0025] The lever mechanism serves to adjust a seat and is designed to release and / or block the translational and / or rotational degrees of freedom of the slide and the seat console. For this purpose, the operating station can have at least one locking device, in particular several, and most preferably a translational locking device and a rotational lock. With regard to safety, blocking the degrees of freedom by the at least one locking device in an unactuated position (zero position) of the actuating element is particularly advantageous.

[0026] The seat console comprises a lever mechanism with a bifunctional actuator, in particular a lever. A bifunctional actuator particularly advantageously enables the execution of two functions, especially the control of two devices for locking the operator's freedom of movement.

[0027] In a preferred embodiment of the invention, the actuating element extends over at least two, and in particular three, sides of the seat console. This allows for particularly easy actuation of the actuating element with the right and / or left hand or with the right and / or left foot.

[0028] A further preferred embodiment of the invention is one in which the actuating element is designed in the form of a bent tube and / or in the form of a sheet metal bent part.

[0029] Preferably, the actuating element can form at least two parallel sections, particularly in the form of a handle, for improved usability. This allows for a wider grip on the actuating element without unnecessary additional material and also facilitates foot-operated operation.

[0030] The lever mechanism is designed to lock and unlock the slide and / or the seat console.

[0031] A particularly preferred embodiment of the invention comprises a locking device, in particular a toothed segment, and more preferably a rack, below the base plate. This allows for particularly efficient use of the available installation space and effective protection of the locking device from contamination.

[0032] A preferred embodiment of the invention is characterized in which the lever mechanism is configured to unlock the slide by moving the bifunctional actuating element towards the base plate. In other words, the bifunctional actuating element, in combination with the lever mechanism, is configured to release one degree of freedom of movement of the operating station, particularly the translational one, in a first actuation direction, especially a downward movement of the actuating element.

[0033] According to a preferred embodiment of the invention, the lever mechanism is designed to unlock the seat console by moving the bifunctional actuating element in a direction away from the base plate. In other words, the bifunctional actuating element, in combination with the lever mechanism, is designed to release, in a second actuation direction, particularly an upward movement, of the actuating element, a freedom of movement, particularly rotational, of the operating station, especially the seat console.

[0034] The lever mechanism is designed to lock the seat console when the slide is unlocked and / or to lock the slide when the seat console is unlocked. In other words, when the translational degree of freedom is released, the rotational degree of freedom remains blocked, and when the rotational degree of freedom is released, the translational degree of freedom of the operator station remains blocked. This makes it particularly easy to prevent unintentional adjustments.

[0035] In a preferred embodiment of the invention, the guide is designed in multiple parts. In particular, the guide can comprise spatially spaced sub-guides that run parallel in their guiding direction. These sub-guides can be designed differently.

[0036] A preferred embodiment of the invention provides that the guide comprises a rod guide and / or a roller guide, in particular a tapered roller guide. This allows the advantages of different guide types to be combined particularly effectively.

[0037] A particularly preferred embodiment of the invention comprises a roller guide with a leading and / or trailing wiping device, in particular wiping brushes and / or an elastomer seal, arranged on the roller guide. This allows for particularly advantageous cleaning of the guide during operation.

[0038] A further preferred embodiment of the invention is one in which the carriage and / or the seat console has a cable feedthrough and electrical control lines of the operator station are routed through the first and / or second through-hole, in particular on and / or in a guide means. This allows for the cost-effective avoidance of a further through-hole in the base plate.

[0039] In a preferred embodiment of the invention, the first and / or the second through-hole is designed for the passage of a cable. The first and / or the second through-hole may have recesses and / or notches, particularly on the first and / or the second through-hole, to guide a cable parallel to the guide means through the first and / or the second through-hole.

[0040] A further preferred embodiment of the invention is one in which a cable channel, in particular a drag chain, is arranged on the guide means. This allows additional cable to be provided and / or received during movement of the carriage and prevents a collision with moving components of the operator station.

[0041] A particularly preferred embodiment of the invention is one in which the guide means is designed to carry a conductor, in particular a cable. For this purpose, the guide means can have a vertical through-hole extending from the underside to the top side of the base plate. Particularly preferred, the guide means can be formed in two parts within a first and / or second through-hole, particularly in the main extension direction of the first and / or second through-hole, with the conductor being guided between the parts of the guide means through the first and / or second through-hole.

[0042] In a preferred embodiment of the invention, the guide means is provided to have reinforcement in the majority of the cable passage area. This enables a particularly protected routing of the line, especially the cable, during the movement of the carriage.

[0043] A further preferred embodiment of the invention is one in which the seat console is height-adjustable and / or tiltable relative to the carriage. For this purpose, the seat console can have a height adjustment and / or a tilt adjustment mechanism. The height adjustment and / or tilt adjustment can, in particular, include a locking device with which the height adjustment and / or tilt adjustment is permanently held in a specific position.

[0044] The problem according to the invention is further solved by a driver's cab with the features according to claim 17.

[0045] The driver's cab according to the invention for a mobile construction machine with a side and / or top opening is designed to accommodate an assembly unit according to the invention as described above by sliding and / or inserting it into the driver's cab. Detailed description of the invention and drawing

[0046] The invention is illustrated in the drawing and explained in more detail with reference to exemplary embodiments. The drawing shows: Fig. Figure 1 shows a construction machine with an embodiment of an operating station according to the invention arranged on the construction machine in a side view; Fig. 2 shows the operator panel Fig. 1 in a cutaway side view; Fig. Figure 3 shows part of the control panel. Fig. 1 in a cutaway side view with slide and guide; Fig. Figure 4 shows a lever mechanism of the control station in a cutaway section. Fig. 1 in a first functional position; Fig. 5 shows in the cut section from Fig. 5 the lever mechanism of the control station Fig. 1 in a second functional position; Fig. Figure 6 shows another vertical section through the operator station. Fig. 1 with a view to cable routing.

[0047] Fig. Figure 1 shows a construction machine 10 with a driver's cab 12 and an operator's station 14 arranged in the driver's cab 12 in the form of an interchangeable assembly unit. The driver's cab 12 has an assembly opening 16 with a clear opening width 18, through which the operator's station 14 can be inserted, in particular slid in, as a complete assembly unit for placement inside the driver's cab 12. For this purpose, it may be necessary that a driver's cab door 20, in particular including the frame structure 22 of the driver's cab door 20, is only attached to the driver's cab 12 after the operator's station 14 has been placed inside the driver's cab 12, or that it is temporarily removed for this purpose.

[0048] Alternatively or additionally, it may be provided that the driver's cab 12 has the mounting opening 16 on the rear and / or the top.

[0049] This allows for a particularly advantageous separate manufacturing of the construction machine 10 and the operator station 14. Furthermore, the particularly simple retrofitting and / or conversion of existing construction machines 10 is advantageous. For example, a defective construction machine 10 and / or a defective operator station 14 can be repaired particularly easily by replacing the operator station 14.

[0050] The operator platform 14 has a base plate 24 which, when installed in the interior of the driver's cab 12, is flush with the cab floor 26. This effectively prevents safety-critical unevenness (tripping hazards) in the driver's cab 12 and simplifies cleaning.

[0051] Fig. 2 shows operator station 14. Fig. Figure 1 shows a vertically sectioned view. A carriage 28 is spaced from the base plate 24 by an air gap and is arranged above the base plate 24. In other words, the carriage 28 is not in load-bearing contact with the base plate 24. A guide 30 is arranged below the base plate 24 of the operator station 14. The base plate 24 has a first through-hole 32 and a second through-hole 34. The through-holes 32 and 34 extend according to Fig. 2 mainly along an axis directed into the plane of the drawing and are designed in the form of slot openings. In other words, the first through-hole 32 and the second through-hole 34 connect the areas below and above the base plate 24.

[0052] The slide 28 is guided on the guide 30 by means of guide elements 36. The guide elements 36 extend vertically from the slide 28, which is located above the base plate 24, through the base plate 24 to the guide 30 located below the base plate 24. Below the first through-hole 32, the guide element 36 is designed as a bushing 36' with a cylindrical recess, in particular a through-hole, and encloses a rod guide 30' of the guide 30. Below the second through-hole 34 of the base plate 24, the guide element 36 is designed as a tapered roller 36''. Complementing the guide element 36 in the form of the tapered roller 36'', the guide 30 has a tapered roller guide 30''.The guide 30 extends in the form of a linear guide predominantly along an axis directed into the plane of the drawing, or parallel to the extent of the first and second through-holes 32, 34. In other words, the guide 30 guides the slide 28 via the guide means 36 along an axis in the main extension direction of the guide 30, or transversely to an orientation of the operator station 14, when the operator station 14 is installed in the longitudinal direction 38 of the construction machine 10 (see . Fig. 1).

[0053] The specification of the installation position refers by way of example to the embodiment shown according to Fig. 1 and may vary depending on the application.

[0054] The guide 30 is arranged on the base plate 24 via a housing 40. In other words, the slide 28 is guided along the guide 30, while the guide 30 prevents any other translational and rotational movements of the slide 28. In the illustrated embodiment, the guide 30 performs a load-bearing bearing function and, in conjunction with the air gap between the base plate 24 and the slide 28, enables the slide 28 to slide spaced apart and without friction over the base plate 24, as well as the guide element 36 to slide within the first and second through-holes 32, 34.

[0055] The guide means 36 is in the embodiment shown according to Fig. The guide element 36 is designed in multiple parts and permanently attached to the slide 28. However, a detachable arrangement on the slide 28 is also generally possible. Furthermore, a one-piece design of the guide element 36 is also conceivable, particularly in combination with a detachable and / or permanent arrangement on the slide 28.

[0056] The base plate 24 has a wiper device 42 in the form of a brush seal in the first and second through-holes 32, 34. The wiper device 42 effectively prevents the ingress of contaminants through the first and second through-holes 32, 34. The illustrated wiper device 42 in the form of a brush seal is to be understood as an example. Further embodiments of the wiper device 42 are conceivable, as are its arrangement in and / or on the through-holes 32, 34 both below and above the base plate 24. Furthermore, an arrangement of the wiper device 42 on the slide 28 or the guide element 36, for example in the form of a brush seal and / or an elastomer sealing lip, is conceivable.

[0057] The housing 40 is designed in the form of an upwardly open basin and has angles to support the base plate 24 that covers the housing 40. The guide 30 and the portion of the guide element 36 located below the base plate 24 are situated within the housing 40. This effectively prevents contamination of the interior of the housing 40, the guide 30, and the guide element 36. For improved stability and support of the base plate 24, the housing 40 also has an inner wall 44.

[0058] The carriage 28 has a seat console 46 arranged on its upper side. The seat console 46 is multi-part and comprises a non-rotating console part 46' and a rotatable console part 46'' arranged on the upper side of the non-rotating console part 46'. The non-rotating console part 46' is detachably attached to the carriage 28 by means of screw connections 48. The non-rotating console part 46' has a vertical cylindrical recess 50 on a vertical axis through its geometric center for accommodating the rotatable console part 46''. Complementary to the console recess 50, the rotatable console part 46'' has a vertical cylindrical projection 52 for accommodating it in the console recess 50. In other words, the rotatable console part 46'' is inserted into the non-rotating console part 46' in the direction of gravity.In the radial intermediate area 54 of the console parts 46', 46'' ball bearings 56 are arranged and ensure a constant equal spacing between the non-rotating console part 46' and the rotatable console part 46'' as well as a relative rotational movement between the non-rotating console part 46' and the rotatable console part 46'' with as little friction as possible about a common vertical axis of rotation R.

[0059] According to the embodiment in Fig. 2, the rotatable console part 46'' forms a radial arm 58, for the arrangement of a control means 60 (see Fig. 1) in the form of a steering unit. This allows the control element 60 to follow the rotational movement of the rotatable console part 46'' particularly advantageously. In general, a detachable or non-detachable arrangement of the radial arm 58 and / or the control element 60 on the rotatable console part 46'' is also conceivable.

[0060] Furthermore, the rotating console part 46'' has an upper platform 62 with a seat 64 detachably attached to it. The seat 64 is fastened to the rotating console part 46'' by means of screw connections. The seat 64 has a height adjustment 66 and a tilt adjustment 68.

[0061] By combined action of the guide 30 and the slide 28 arranged thereon via guide means 36, the non-rotating console part 46' and the rotatable console part 46'', the seat 64 and the control means 60 can be moved translationally in a transverse direction in a plane parallel to the base plate 24 and rotated about a vertical axis of rotation R relative to the base plate 24. Alternatively or additionally, a superimposed movement in the vertical direction or a tilting movement out of the plane parallel to the base plate 24 can be effected by the height and / or tilt adjustment 66, 68 of the seat 64.

[0062] Fig. Figure 3 shows the base plate 24, the slide 28, the guide 30, the guide means 36 and the housing 40 in a vertical cross-section of the operator station 14. Fig. 1 and Fig. 2.

[0063] Below the base plate 24, the operator station 14 has a locking device 70 with a fixed locking component 70' in the form of a toothed segment extending parallel to the guide 30 and a movable locking component 70'' in the form of a bolt. In a locked state, the movable locking component 70'' engages with the fixed locking component 70' and thus prevents relative movement of the components to each other.

[0064] Fig. Figure 4 shows a detailed view of operator station 14 from the Fig. 1 and Fig. 2. The fixed locking component 70' is permanently attached to the housing 40. The movable locking component 70'' is connected to the slide 28 and the console part 46'' via a lever mechanism 72. The lever mechanism 72 comprises a sliding mechanical part 72', which is arranged on the underside of the slide 28 via a first pivot joint 74, and a rotatable mechanical part 72'', which is arranged on the rotatable console part 46'' via a second pivot joint 76. The rotatable mechanical part 72'' moves synchronously with the rotatable console part 46'', and the sliding mechanical part 72' moves synchronously with the slide 28. The rotatable mechanical part 72'' is connected to the sliding mechanical part 72' via a loose vertical through-connection 78.The through-connection 78 is located in the center of rotation of the rotatable console part 46'' and enables a translational vertical movement as well as a rotational movement between the sliding and the rotatable mechanical part 72', 72''.

[0065] In the locked state (see Fig. 3) The locking device 70 blocks the immediate translational movement of the rotatable console part 46'' and, consequently, prevents the translational movement of the arranged non-rotatable console part 46', the slide 28, and the guide means 36 along the guide 30. In other words, the locking device 70, when locked (see Fig. 3) the translational relative movement between seat 64 and base plate 24.

[0066] In an unloaded state of the lever mechanism 72 – without external influence by a user – the lever mechanism 72 is in a neutral position and the locking device 70 is in a locked position. This prevents unintentional translational movement of the seat 64. The through-connection 78 is in its neutral position in its maximum insertion position. In other words, the sliding mechanical part 72' relative to the rotatable mechanical part 72'' can only be moved downwards in the vertical direction along the through-connection 78.

[0067] The lever mechanism 72 has an actuating element 80 in the form of a lever, arranged in the second pivot joint 76, for transmitting torque to the lever mechanism 72. When the seat 64 is aligned in the longitudinal direction 38 of the construction machine 10, the actuating element 80 forms a lever arm in the longitudinal direction 38 of the construction machine 10. It should be noted, however, that the orientation of the lever is only relevant with regard to operation by the user, since the mechanical coupling of the rotatable mechanical part 72'' with the sliding mechanical part 72' takes place at the center of rotation of the rotatable console part 46'', and the mechanical function is therefore independent of any rotation of the seat 64 relative to the base plate 24.

[0068] Fig. Figure 4 shows the locking device 70 in an unlocked state. Applying torque to the second pivot joint 76 as a result of a downward movement (towards the base plate 24) of the actuating element 80 causes a rocker arm 82 of the rotatable mechanical part 72'' to rotate, thereby moving the through-connection 78 downwards in a vertical direction. The downward movement of the through-connection 78 causes, on the one hand, a rocker arm 84 of the movable mechanical part 72' to lower and, due to the rotatable arrangement of the rocker arm 84 on the first pivot joint 74, on the other hand, the movable locking component 70'' located at the end of the rocker arm 84 to rise. This deflects the movable locking component 70'' vertically upwards out of its engagement with the stationary locking component 70'.The blockage of movement in the direction of the guide 30 is thus no longer present, and the seat 64, together with the seat console 46 and the slide 28, can be adjusted in its relative position to the base plate 24 along the direction determined by the guide 30. Once the desired adjustment of the seat 64 has been achieved and the torque on the lever mechanism 72 is released by releasing the actuating element 80, the lever mechanism 72 returns to the zero position by means of a return device 86 in the form of a defined weight on the movable locking component 70'', and the movable locking component 70'' lowers back into the engaged state with the stationary locking component 70'.

[0069] The seat console 46 has a rotary locking mechanism 88 with a stationary rotary locking component 88' in the form of a radially rotating toothed ring, which is fixedly arranged on the non-rotating console part 46', and a movable rotary locking component 88'' in the form of a bolt, which is rotatably arranged on the rotatable console part 46'' about a horizontal axis 90. In the locked state of the rotary locking mechanism 88, the movable rotary locking component 88'' is engaged with the stationary rotary locking component 88' and blocks the relative movement between the non-rotating console part 46' and the rotatable console part 46''. In other words, the seat 64 cannot be rotated about a vertical axis when the rotary locking mechanism 88 is locked.

[0070] In an unloaded state of the lever mechanism 72 – without external influence by a user – the lever mechanism 72 is in the neutral position and the rotary lock 88 is in a locked position. The rotatable rotary lock component 88'' is loosely arranged on the rotatable mechanical part 72'' of the lever mechanism 72 in the neutral position of the lever mechanism 72.

[0071] When torque is applied as a result of a downward movement of the actuating element 80 onto the rotatable mechanical part 72'' for the purpose of unlocking the locking device 70, the end of the rocker arm 82 of the rotatable mechanical part 72'' opposite the through-connection 78 detaches from the movable rotary locking component 88'' as a result of the downward movement of the end of the rocker arm 82 arranged at the through-connection 78 and forms a functionally necessary gap 92 to the movable rotary locking component 88'' which remains in its position. This ensures that unlocking the locking device 70 does not simultaneously unlock the rotary lock 88.

[0072] Fig. Figure 5 shows the unlocked state of the rotary lock 88 of the operating station 14 from the preceding figures. By an upward movement (in a direction away from the base plate 24) of the actuating element 80, the end of the rocker arm 82 of the rotatable mechanical part 72'', which is arranged at the through-connection 78, is moved upwards.

[0073] This causes the through-connection 78 to slide upwards out of the movable mechanical part 72' without forcing it into an upward movement. As a result, the movable locking component 70'' remains engaged with the fixed locking component 70' of the locking device 70, and the blockage of translational movement along the guide 30 remains in place. In other words, the seat 64 cannot be moved.

[0074] Simultaneously, lifting the end of the rocker arm 82 of the rotatable mechanical part 72'', which is arranged at the through-connection 78, inevitably causes a downward movement of the end of the rocker arm 82 that is loosely arranged on the movable rotary locking component 88'' and is opposite the through-connection 78. This causes the rotary locking component 88'', in the form of the bolt, to rotate about the horizontal axis 90 and be deflected from engagement with the fixed rotary locking component 88', in the form of the toothed ring. With the release of the rotary locking component 88, the rotational degree of freedom of the rotatable console part 46'' relative to the non-rotatable console part 46' is released, and the seat 64 can be rotated relative to the base plate 24.

[0075] When the pulling force on the actuating element 80 is removed, the lever mechanism 72 returns to its neutral position and the movable rotary locking component 88'' rotates, supported by a return-rotating device 94 in the form of a return spring, around the horizontal axis 90 back into engagement with the stationary rotary locking component 88'. This reliably prevents uncontrolled rotation of the seat 64.

[0076] In summary, it can be seen that the actuating element 80 releases the locking device 70 by a downward movement, allowing the seat 64 to be adjusted along the guide 30 without unlocking the rotary lock 88. Furthermore, an upward movement of the actuating element 80 releases the rotary lock 88, allowing the seat to be rotated, without releasing the locking device 70. The actuating element 80, in the form of a lever, is therefore bifunctional. In the neutral position of the lever mechanism 72 and the actuating element 80, both the locking device 70 and the rotary lock 88 are locked.

[0077] Fig. Figure 6 shows another parallel to the sections from the Fig.Figure 2-5 shows a vertical section through the operator station 14 and serves to illustrate a cable routing 96. The cable routing 96 represents one or more cables and lines arranged at the operator station 14 for data transmission and power supply between the operator station 14 and the construction machine 10. Inside the housing 40, the cable routing 96 is supported by a flexible cable guide 98 in the form of a drag chain, arranged on the guide element 36. When the seat 64 is adjusted, the cable routing 96 can provide and / or receive additional cable. This enables controlled receipt and release of a cable and / or line during the adjustment process of the seat 64 without the risk of the cable routing 96 colliding with moving components of the operator station 14.

[0078] The guide element 36 has a vertical guide element recess 100. The guide element recess 100 extends from a region of the guide element 36 formed below the base plate 24 to a region of the guide element 36 formed above the base plate 24. In other words, the guide element 36 has a guide element recess 100 through which the cable routing 96 extends within the guide element 36 from the underside of the base plate 24 to the top side of the base plate 24. This eliminates the need for a further through-hole in the base plate 24. The cable routing 96 runs along the moving components of the operator station 14.

[0079] The cable routing 96 extends via a through-hole in the slide 28 and the cylindrical console recess 50 to the upper platform 62 of the rotatable console part 46'' and further to the seat 64 and to the control means 60.

[0080] Taking together all the figures of the drawing, the invention relates to an operating station 14 designed as an interchangeable assembly unit with a slide 28 for translational and a rotatable seat console 46 for rotational adjustment of a seat 64, as well as a driver's cab 12 with such an operating station 14.
