The invention relates to a lift folding system. A lift-and-fold system can be a lift-and-fold door to close off a building opening forming an entrance or driveway, or a lift-and-fold shutter to close off a building opening forming a window. The invention thus relates to a folding lift system or a folding lift gate according to the preamble of claim 1. The folding lift system is preferably described below using the example of a folding lift gate. The folding lift system can also be a folding lift shutter with the features of the folding lift gate described here. The lifting folding door can be installed in or on a building wall where the building wall has an opening for the door or for the shop. Such building openings are usually spanned by a lintel. The lift-and-fold system (lift-and-fold gate) can be mounted with or in a (gate) frame. The frame can have laterally arranged frame side parts include. The frame side parts can include (guide) rails or be formed from them. A guide element arranged on the lifting folding door or shutter is guided in the guide rails, as a result of which the movement of the lifting folding system is guided. The folding lift gate is suitable for being opened via a (gate) drive device by raising the folding lift gate and for being closed by lowering the folding lift gate. The drive device comprises at least one drive shaft. The driveshaft may be substantially parallel to the camber. The length of the wave can correspond or almost correspond to the width (or the longitudinal extension) of the camber. The overall length of the shaft can be less than the camber width. The drive shaft can be formed in several parts. The shaft parts can be arranged collinearly. A drive shaft arrangement with a plurality of drive shafts can also be provided, in which case each of the shafts can be oriented (substantially) perpendicularly to the (longitudinal) direction of the camber. The drive device is—directly or indirectly—attached to the building wall in the area of the building opening, in particular on the lintel or in the area of the lintel. The lifting and folding system or the lifting and folding door comprises a pair of wings, which has a floor-side floor wing and a lintel-side fall wing rotatably connected to the floor wing by a wing pivot joint and rotatably mounted on a lintel joint in the area of the lintel. The bottom wing can be formed as a bottom gate wing and the lintel wing as a lintel gate wing. Floor gate leaves and lintel gate leaves are arranged in one (gate) level, the system level, when the lifting folding gate is lowered. When the lifting folding door is open, the (door) leaves are in a V-shape adjacent to one another and are arranged outside of the system level. The raising and lowering of the lifting and folding door (lifting and folding system) is effected by at least one tension element which is fastened to the floor door leaf, in particular near the floor, and which can be moved via the drive shaft. At least one locking device is provided with which the lifting folding door and/or the lintel door leaf and/or the floor door leaf and/or the tension element can be locked in the closed position.

A drive device is provided for a lifting-folding system (lifting-folding door)—particularly described here. The drive device includes at least one drive shaft, which can be driven, for example, via a drive motor. A hydraulic drive for raising/lowering the lift-and-fold system can also be provided.

A frame or gate frame is provided for mounting a lift-and-fold system (lift-and-fold gate)—particularly described here. The frame includes laterally in or Frame side parts that can be arranged at a building opening. The frame side parts can include (guide) rails or be formed from (guide) rails.

A locking device, in particular one that can be retrofitted, is suitable for a folding lift system or folding gate, in particular one that is described here. It comprises at least one locking element that can be moved into a locking receptacle.

TECHNOLOGICAL BACKGROUND

A Hebefalttor is for example in the DE 2 001 349 A1 described. The door shown there comprises an upper, ie lintel-side, door leaf and a lower, ie ground-side, door leaf. In the closed position, both gate leaves are arranged on one level. Both gate leaves are connected to one another with a horizontally oriented swivel joint. A drive device is arranged on the upper gate leaf, which comprises a drive shaft and with which a traction cable attached to the lower gate leaf can be wound up and unwound on a drum. The lower gate leaf is thus pivoted relative to the upper gate leaf about the axis of rotation arranged between the gate leaves. At the same time, the upper gate leaf pivots upwards around a pivot axis in the area of the lintel. In the open position, the gate leaves are in a V-shaped position. To open, a drive device pulls the lower gate leaf upwards via a traction cable. The engine of the drive device is in accordance with the DE 2 001 349 A1 placed on the upper gate leaf. Such gates are locked, for example to prevent unwanted opening, by actuating a safety bar arranged on one of the gate wings in the area of the pivot joint between the wings, which interacts with the other gate leaf, and by - starting from the closed gate position - A movement of one wing is blocked relative to the second wing.

Particularly in the case of very wide lifting folding doors, such as a bifold (hangar) door, comparatively high forces/torques are required to lift/lower them due to their own weight. Unless the engine - as in the DE 2 001 349 A1 described - is attached to the gate, this effort is increased by the effort to lift the motor. In the case of very wide gates, a considerable amount of force can be required to raise the gate or to brake when lowering the gate. In addition, with wide gates, the raised gate leaves may sag. The deflection can be caused by the drive motor attached to the door or by its own weight the material from which the gate leaves are made. If an additional force is applied to the door, for example due to wind force or the use of force, the locking mechanism in the area of the pivot joint may fail. This is where the invention comes in.

the EP2540929 A1 and the US3442318A1 disclose lift-fold systems with latches.

PRESENTATION OF THE INVENTION

The object of the invention is to improve the handling and securing of folding lift systems, in particular folding lift gates. This object is achieved by a folding system (folding gate, folding shutter) according to claim 1. Configurations of the lift-and-fold system/lift-and-fold door according to the invention result from the dependent claims. In the following, the term lifting folding door is regularly used, whereby what is described can also refer to features of the lifting folding system. In the case of the folding lift gate according to claim 1, it is accordingly provided that the locking device can be locked or unlocked via the drive device, via a locking driver connected to the drive device. The locking device is unlocked before the lifting folding door is raised. The locking device is locked after the lifting gate has been lowered. It is provided that the locking device comprises at least one locking element, in particular formed as a claw or hook or pliers, which mechanically interacts with a locking receptacle arranged in and/or on the floor. The interaction of the locking device with the locking receptacle arranged in the area of the middle of the wing or the center of the gate (i.e. between the lateral frame parts) on or in the floor provides an (additional) lock which prevents the gate or one of the gate wing or the folding shutters from being blown open by wind force or external (violent) influence can be moved or bent, especially in the area of the locking mount. It is also possible to provide a plurality of locking receptacles, with which a locking element interacts in each case, so that the locking device comprises a plurality of locking elements. The interaction of the locking element with the locking receptacle preferably takes place during or for locking. During or for unlocking, the locking element is moved or released from the locking receptacle. If the locking element is formed as a claw, for example, the interaction consists in the claw engaging behind a rod or a resistance element for locking. To unlock, the claw is turned or adjusted so that between the locking element and the locking receptacle there is no longer any mechanical interaction.

The locking device can comprise at least one second locking element, in particular formed as a bolt, which mechanically interacts with a locking receptacle arranged in and/or on a frame side part for locking. The lateral (additional) locking device prevents the door from being opened unintentionally in the area of one or both frame side parts. The frame and/or the frame side parts can be a (fixed) part of the lift-and-fold system. According to one embodiment, several locking elements and correspondingly several locking receptacles can be provided per frame side part, for example an (additional) locking device can be provided for each wing on each of the sides.

The side lock can also be arranged in the frame, for example in the frame side parts. In this case, locking drivers are guided in or on the frame. For locking purposes, locking bolts of this variant engage in recesses or openings which are arranged in the lifting folding system, for example in the bottom wing and/or lintel wing. Locking hooks of this variant of the side locking can, for example, engage behind rods or projections in or on the wings. At least one opening (receptacle) is preferably arranged on the floor or near the floor, resulting in a lateral and floor-close locking. A combination of a side lock arranged on the sash (pair) and a side lock arranged in/on the frame can also be provided.

According to one embodiment of the lift-and-fold system, it can be provided that the locking device comprises a plurality of locking elements, with at least one (first) locking element interacting with a locking receptacle arranged on the bottom, i. H. with a locking receptacle arranged in and/or on the floor, and wherein at least one (second) locking element interacts with a laterally acting locking receptacle, d. H. with a locking receptacle arranged in and/or on a frame side part or with at least one locking element arranged in or on the frame. Accordingly, the gate is locked at the bottom and side. If the system is designed as a shutter, the floor-side locking receptacle is arranged in the area of the underside of the window or the window sill.

In all configurations of the locking device, when the gate or shutter is in the locked state, there is no unwanted movement, ie unwanted lifting/pivoting of the gate/shop or at least one wing, is prevented, or at least made considerably more difficult. In particular, the interaction of the locking element and locking receptacle components makes the gate or shutter more secure against unwanted opening. For example, opening the gate (shop) by unauthorized persons is made considerably more difficult.

A cable, a belt, a toothed belt and/or a chain can be provided as the traction element. A pulling element can be guided or wound up and/or unwound by means of a roller or drum, in particular a toothed roller. A chain drive can be provided to raise/lower the system. Tension and/or drive elements can be arranged, in particular guided, in the frame. The frame can include a frame.

It is envisaged that the locking receptacle is designed as a pocket with a bar for gripping behind a claw, a hook or for gripping with pliers and the second locking receptacle is designed as a pocket for a bolt. The pocket can be a recess, free space or trough in the floor area or be formed in the area of the lower edge of the window. The geometry of the pocket can be adapted to the dimensions of the locking element, for example to the dimensions of the bolt, in such a way that the locking element or the bolt can be inserted into the pocket with some play.

According to a further variant of the door, the locking device can additionally include a surface lock, in particular a center lock. The surface lock is actuatable via a surface lock driver. It is suitable for locking the position of the bottom wing and/or the fall wing in the closed position, particularly in the area of the wing pivot joint. For example, the door surface locking mechanism can include bolts that engage laterally in suitable receptacles that are arranged in the frame or in the frame side parts. The locking driver of the locking device can comprise a cable pull, a bowden cable or a driver linkage. Conveniently, the lock driver is on the gate, e.g. H. on one or both gate leaves. Alternatively, the locking driver can be arranged in or on the frame.

It is expedient if the locking device is actuated while the drive device is running free, before lifting or after lowering of the lifting folding system. Freewheeling includes the rotation of the drive shaft or movement of drive components where there is still no door or shutter movement, since pulling or lifting devices, cables, chains, belts, hydraulic devices or comparably acting components are not yet (raising) or no longer (lowering) . When raising the lift gate, this occurs during the first revolution(s) of the drive shaft before the gate is moved. The shaft rotates, thereby actuating the driver or drivers of the locking device, and only then are the pulling elements subjected to forces and the gate is raised. When lowering, the sequence is reversed: the gate is moved to the closed position, the drive shaft rotates a little further, thereby actuating the drivers for the locking device.

An additional traction element is provided, which supports the traction element mechanically. The additional tension element can be arranged, for example, between the frame side parts, approximately in the middle between the frame side parts. The additional tension element can include a locking driver for actuating the locking device or can be formed from a locking driver. The cable of a locking driver can also be used as an additional pulling element.

The configurations of the lifting folding system described here can each comprise a deflection system which is suitable for deflecting the tension element and/or the or an additional tension element. The deflection system can be associated with a locking driver. The direction of action of a tension element and/or a driver and/or an additional tension element is changed by the deflection system. If the traction element is formed as a cable, the deflection system can include one or more deflection pulleys, for example. The deflection system or a deflection roller can be attached to the gate, d. H. on one or both gate leaves. Provision can also be made for the deflection system to be arranged, at least in sections or in part, or a deflection roller on the frame (side part).

Provision can be made for the locking device, in particular the or a locking element, to be actuated against the action of a restoring force, in particular against the action of a spring. In connection with the deflection system, it is achieved that a locking element is in the locking position without its being actuated, ie in a position in which the element protrudes beyond at least one of the edges of the door. It is actuated by tensile forces, which are generated by deflection rollers are oriented on the gate/shop in such a way that the locking element is moved towards the gate, ie in such a way that it no longer protrudes over the edge of the gate. This takes place against the action of a restoring force of a spring. The stopping of these tensile forces allows the spring forces to take effect and the locking element moves into the locking position. The spring can be designed as a tension spring, for example for resetting a locking bolt, or as a torsion spring mechanism for resetting a hook or a claw or the like. If the locking device is (at least predominantly) arranged in or on the frame, provision can be made for the locking element (the bolt or bolts) to engage in the recess in the gate/shutter against the action of a spring, and for unlocking by means of a driver arrangement to use the force of the restoring spring would be overcome.

The traction elements described here and/or the or an additional traction element can be formed at least in sections as a cable and/or as a Bowden cable and/or as a belt and/or as a toothed belt and/or as a band.

The drive device comprises a drive console, which is preferably arranged between the lateral frame borders, approximately in the middle or almost in the middle between the frame side parts. Alternatively, the drive bracket can be arranged laterally, for example on the frame or next to the frame, in particular on a side part of the frame. This is particularly useful for gates whose gate width is less than about 6m. One or the drive shaft is rotatably mounted on the drive console. The drive console can be formed as a center console or side console. The drive motor of the drive can be arranged on the console. The console, in particular the center console, can be mounted on the lintel of the building opening. If the drive shaft is formed in several parts, several consoles can be provided for each lifting and folding system, for example one or more side consoles or a center console and at least one side console.

A guide element, formed in particular as a roller or drum, for example a tension element guide means and/or driver guide means, for guiding the (additional) tension element and/or the locking driver, is arranged on the drive console. The guide element is mechanically coupled to the drive shaft. The torque is transmitted from the drive shaft to the roller/drum, which is non-rotatably connected to the drive shaft, and from there—via a guide element—to the tension element and/or the driver.

According to a preferred embodiment of the lifting folding system designs described here, at least one weight-compensating means, guided in particular in or on the frame, can be provided. The weight force compensation achieved in this way relieves the drive device and/or the drive bracket. The weight force compensation can be achieved by one or more counterweights, which are arranged, for example, on at least one traction cable or on at least one chain or on a toothed belt. If the weight of the counterweights corresponds almost to the weight of the gate leaf (dead weight of the system), the gate or shutter can be raised or lowered with very little effort.

An anti-fall means can be provided to secure the gate/shop against uncontrolled falling. The anti-fall device can include an (emergency) brake, which intervenes in the drive movement and/or in the movement of the lifting and folding system if one of the components involved, such as a tension element, fails, for example due to a break or crack.

The drive device comprises at least one drive console that can be fastened to a building wall, in particular to a lintel of a building opening in a building wall or to a frame or to a console. At least one drive shaft or at least a section of a multi-part drive shaft is rotatably mounted in the drive console. Several shafts can also be provided, in which case the axis of rotation of the shafts can run parallel to the lintel or perpendicular to the lintel. A rope can be wound up on the shaft or on one of the shafts. A drum arranged on the shaft can be provided, in particular for winding/unwinding a traction cable or a driver cable. The drive console comprises at least one guide element fastened to the drive shaft, for example a driver guide means for guiding a driver or a driver component for actuating a locking and/or pulling device of the lifting folding system.

The frame can be formed as a guide rail for components of the lift-and-fold system or can include at least one guide rail. The guide rail can be mounted on the building wall. The (gate) frame comprises frame side parts that can be arranged laterally in or on a building opening. Each frame side part can include a guide rail or be formed as a guide rail. In or on the frame, a drive device can be arranged or arranged. Preferably, the frame includes drive means as described herein for driving the lift-and-fold system.

The frame may include locking means for laterally locking the lift fold system. If the locking device includes a locking driver (cable), this is guided, at least in sections, in or on the frame. A locking element of the locking device, such as a bolt, is moved by means of a driver and, when locking, engages in an opening/recess in the gate or shutter. The lock receptacle can include a lock driver that can be actuated via a door drive device of the lifting folding door. The locking element can be actuated with the driver. The locking element can be formed as a bolt or as a claw or as a hook or as a pair of pliers or combinations thereof. The locking element interacts mechanically with a locking receptacle arranged in and/or on the floor and/or in and/or on a goal frame (side) part of the goal frame of the folding lift gate and/or in the folding lift system.

An improvement in the handling and securing of generic gates or shops with a comparatively large (gate) width results in particular from a lift-and-fold system comprising a combination of the features according to a floor-side and optionally also lateral locking device described herein and according to the additional tension element described herein and according to Drive device described herein with the drive console described herein.

An improvement in the handling and securing of generic gates or shutters with a common width or a standard width results in particular from a lifting and folding system comprising a combination of the features according to a floor-side and optionally also a lateral locking device described here and according to the drive device described here with the drive console described here .

The components to be used according to the invention mentioned above and claimed and described in the exemplary embodiments are not subject to any special exceptional conditions in terms of their size, shape, choice of material and technical design, so that the selection criteria known in the field of application can be used without restriction.

Further details, features and advantages of the subject matter of the invention result from the dependent claims, as well as from the following description and the associated drawing, in which - by way of example - an embodiment of a lifting folding system, namely a lifting folding door, is shown.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

A front view of a Hebefalttor 1 can der 1 be removed. The lift-and-fold door forms a lift-and-fold system for a door opening, ie for a building opening on the ground. The in the Figures 1 to 11 The features shown can also be implemented in a lifting folding shutter that is not shown here. The lifting folding door 1 according to the figures is referred to as "door" in the following. According to 1 Gate 1 is shown in the closed gate position. The gate 1 comprises two gate leaves 2, 3, namely a lintel-side (upper) Lintel gate leaf 2 and a floor-side (lower) floor gate leaf 3. The two gate leaves 2, 3 of gate 1 are located at in 1 Gate position shown in the gate level, which according to 1 lies in the drawing plane. The gate leaves 2, 3 are connected to one another via a wing pivot joint 6.

The gate 1 is mounted in an opening in a wall 4 of a building. The lintel 5 is located above the gate 1. The pair of wings (2, 3) is arranged in a gate frame 7. The frame 7 comprises two frame side parts 8. The floor 9 is shown below the floor-side floor door leaf 3.

A side view of a gate 1 in the open position can be seen in FIG 2 be removed (sectional view). The floor-side floor gate leaf 3 was pulled upwards in a guide by means of tension elements 10 . The gate 1 is "folded" in the process, ie the wings 2, 3 rotate about the axis of rotation of the wing pivot 6 and, in the open position, form a (according to 2 lying) "V". When closing, the angle of the "V" increases until both legs of the "V" as in 3 can be seen are arranged in one plane.

A side view of the gate 1 in the closed position is shown in FIG 3 to see (section view). The gate level runs according to 3 perpendicular to the drawing plane. In the area of the lintel 5, a lintel joint 41 is arranged. The lintel gate leaf 2 is rotatably attached to the lintel 5 with the lintel joint 41 . When the gate 1 is opened (raised) and closed (lowered), the joints 6 (leaf pivot joint) and 41 (lintel joint) are accordingly actuated.

A sectional view from above of the gate 1 according to FIG 1 show the 4 . Accordingly, the frame side parts 8 are arranged in recesses 11 in the wall 4 . In the frame side parts 8 toothed belts 12 run, to which weights 13 are attached. The weights 13 compensate for the dead weight of the door 1. The drive shaft 15 extends almost over the entire width of the door 1. The drive shaft 15 is mechanically connected to the drive motor 18. The drive motor 18 is attached (by means of the drive bracket 16) to the wall 4 and rotates the shaft 15 to raise the door 1 in one direction of rotation and to lower the door 1 in the other, opposite direction of rotation. A gear can be provided between the motor 18 and the shaft 15 . Tension elements 10 are connected to the drive shaft 15 in a rotationally fixed manner, with which in particular the floor gate leaf 3 can be pulled upwards. To become lifting Tension elements (10, 12) are guided, for example, via teeth, preferably in the side parts 8 of the frame. An enlarged detailed view of a (related to 4 shown on the right) frame side part 8 can figure 5 be removed. It can be seen there that each toothed belt 12 runs over a toothed wheel 14 which is connected to the drive shaft 15 in a rotationally fixed manner. Toothed belts are suitable for transmitting forces in both directions of rotation of the rotating shaft, which is useful for a weight-balanced gate 1.

A detail according to the supervision 4 show the 6 . The drive console 16 is shown there, in which at least one drum 17 for guiding/winding a cable pull of a locking driver 19 is arranged. The locking driver 19 includes the (wire) cable with which the locking element 20 can be actuated.

the Figures 8A , 8B , 9A , 9B , 10A and 10B show details, possibly of various locking devices 43, comprising various locking elements (20, 27) in different positions (each as a sectional view). Figure 8A shows a detailed view of a lateral sectional view of a gate 1, wherein a locking element 20 not according to the invention is formed as a bolt 21.

According to Figure 8A the bolt 21 is shown in the unlocked position, ie in the open position of the locking element 20 . According to Figure 8B the bolt 21 is shown in the locked position. The bolt 21 engages in the locked position ( Figure 8B ) into a locking receptacle 24. The locking receptacle 24 is formed in such a way that the bolt 21 can be inserted into the receptacle 24 at least in sections. The receptacle 24 has an essentially cylindrical geometry, with the essentially cylindrical bolt 21 being insertable into the receptacle 24 with some play. The receptacle 24 is located in the floor 9 under the floor gate leaf 3.

According to the Figures 10A and 10B According to the invention, the locking element 20 is formed as a hook 22 which can be pivoted into a locking receptacle 24 formed as a pocket 23 and arranged in the base 9 . In the pocket 23 there is a rod 25 with which hooks 22 interact for locking. In the locked state, the hook 22 engages behind the rod 25 in the pocket 23. A restoring means is not absolutely necessary for the hook.

Bolt 21 and hook 22 according to Figures 8A /B and 10A/B are arranged between the frame side parts 8, i.e. approximately in the center of the goal. It can be provided with very wide gates several bolts / hooks, such as a locking element 20 in the right half of the goal and one in the area of the left half of the goal. In addition, a door surface or central locking device 44 can be provided.

The bolts 21 are actuated against the force of a spring. In this respect, the locking device comprises a restoring means. Accordingly, opening requires a pulling force by means of a driver 19 against the action of the spring. When closing, the pulling force is released and the spring pushes the locking element (21) into the corresponding seat (24).

A side lock 26, the details according to Figures 9A and 9B be removed. The opened side lock is in Figure 9A shown, the closed in Figure 9B . According to Figure 9B the laterally acting locking bolt 27 engages in a recess 28 in one of the frame side parts 8.

The Figures 9A and 9B a spring element 29 which acts on the locking bolt 27 can also be removed. The spring 29 presses against the bolt 27 so that the bolt 27 is moved against the action of the spring 29 for unlocking.

The driver assembly (19) for actuating the side lock 26 can figures 1 and 9A /B can be taken. According to this, before the gate 1 is raised, ie while the drive shaft 15 is running free, at least one drum 17 is rotated, as a result of which a driver 19, namely at least one cable pull 30, is moved. Via a deflection system 31 with deflection rollers 32, the initially vertical tensile force of the traction cable 30 is deflected into a horizontally acting tensile force. In the area of the side lock 26, the direction of the tensile force is reversed by means of a deflection roller 33, as a result of which the locking bolt 27 can be moved away from the frame side part 8 (unlocking) or toward the frame side part 8 (locking). The locking takes place following the closing movement of the gate 1 during the freewheeling of the shaft 15, the unlocking during the freewheeling before the lifting of the gate 1. According to FIG Figures 1 to 10A /B, the door 1 comprises, in addition to the center lock 44 known per se, a right-hand side lock 26, a left-hand side lock 26 and a lock (20) acting on the ground.

A drum 17 may be provided in the power or center console 16 for each side latch 26 . There can be a (coupled) driver for side and bottom locks with a (common) drum. On each drum 17 is a traction cable 30 arranged, which is guided over components of the deflection device 31 to the side locks 26. A front detailed view of the center console 16 can 7 be removed.

The figures 6 and 7 the arrangement of the drive motor 18 on the drive console 16 can also be seen. Accordingly, the motor 18 is not arranged on one of the gate leaves 2, 3 of the gate 1 but on the lintel 5 to which the drive bracket 16 is attached. Additional pull elements 34 for raising/lowering the door 1 can be provided in or on the drive bracket 16 . Thus, when the door 1 is lifted, it is not only pulled up laterally, ie in the area of the frame side parts 8, but also in the area of the center of the door, ie where the additional tension elements 34 are fastened on the door side. A sagging of the lifting door 1 in the center of the door due to the weight of the door leaves 2, 3 is avoided or at least reduced. The additional tension element 34 pulls a lower load than the lateral tension elements 10. The drive motor 18 or a bracket for the drive motor 18 can alternatively be provided in the area of the frame side parts.

A perspective view of the gate drive device 42 with the console 16 can of 11 be removed. Accordingly, the console 16 comprises a console frame 35 on which a motor mount 36 is arranged. The motor 18 is attached to the motor mount 36 by screws. Bearings 37 for receiving the drive shaft 15 are arranged in the console frame. The drive shaft 15 is connected to the motor 18 in a torque-proof manner. A rectifier module 38 is arranged on the housing of the motor 18 . Because the door 1 is mounted and guided in a manner balanced by weights 13 , the motor 18 has to provide comparatively low torques for raising/lowering the door 1 . The center console 16 is attached to the lintel 5 by means of attachment plates 39.

the 11 the drum(s) 17 can be removed, which is (are) arranged on the drive shaft 15 in a rotationally fixed manner. The drums 17 are thus rotated with the shaft 15.
