Description

The invention relates to a shaft scaffolding for an elevator installation, which can be arranged free-standing and / or in a lift shaft and serves to receive a lifting device, which is connected via at least one drive shaft connected to a drive motor, horizontally mounted on the shaft frame or in the drive shaft drive shaft by means of Tragmittein, in particular a Zugmitteleinrichtung is moved up and down the shaft frame.

There are already generally simplified elevator systems for the disabled known. These are mainly used in private residential areas for the barrier-free transport of persons with disabilities and are also known in common usage under the term "home lift".

In the absence of a harmonized European standard, which has hitherto been available only in the form of prEN 81-41: 2007 as draft for examination and public opinion, for example in Germany following the requirements of Directive 2006/42 / EC - simplified Machinery Directive called - manufactured and installed. This guideline allows z. B. by using a Todmannsteuerung, d. H. the lift can only be moved as long as an operating button is pressed manually, at a maximum operating speed of 0.15 m / s and other measures to dispense with a cabin door. Furthermore, the Machinery Directive allows reduced over- (shaft heads) and underpasses (shaft pits) to execute.

The shelters required for the maintenance and inspection of the facilities are temporarily made. For elevator systems of this kind, as a rule, no safety-related acceptance by a notified body is required up to a delivery height of 3 m, provided that the manufacturer's factory has the corresponding manufacturer's certificate features. The lift height is the travel distance that the platform can cover at maximum.

Simplified elevator systems of this type can be used in lift shafts, which i. d. R. bricked or concreted are mounted. In most applications, however, these systems are delivered with a hoistway scaffold. This can be mounted as a load-bearing or self-supporting shaft scaffolding indoors or outdoors. The load-bearing shaft framework construction consists of posts or longitudinal struts and bars in the form of steel profiles, usually hollow steel profiles. In order to create a barrier that is closed at least over the travel path, shaft scaffolds are often lined with glass, façade panels or other material.

As a drive system mainly spindle drives and hydraulic drive systems are offered on the elevator market. Here, the drive spindle or the hydraulic ram and the guide system are mounted on a side wall or the rear wall side. The elevator platforms are guided cantilevered on one side as a "backpack system". The drive motor or the hydraulic unit is located either on the drive side behind a veneer (spindle drives) or outside the elevator shaft (hydraulic units).

In both drive systems, a side or rear wall is installed by the required technology (drive spindle, hydraulic ram, guide rails, etc.). This wall side can, if architecturally desired, be clad. In shear and crushing hazards by the driving motion such a wall cladding is mandatory. With glass elevators, the resulting reduced transparency is distracting.

The clad wall side can not continue to be used for a possible car access and also requires additional space. In addition, "backpack systems" are inferior to centrally suspended systems Driving characteristics, which manifests itself for example by stick-slip effect and resulting car vibrations during the driving movement. Among other things, this leads to higher noise emissions, which in homes lead to impaired living comfort.

Furthermore, an elevator system with at least two stops from the EP 1 741 660 A1 known, which has a drive motor with a vertically extending drive axle and an attached drive pulley and support means. The elevator system is equipped with an elevator platform with a traveling frame, which is carried by the support means and moved up and down. The support means for the elevator platform run, inter alia, diagonally across the corner and on both sides of the elevator system, so that a lot of space is required for the drive device. With a ratio of 2: 1 or a larger gear ratio further space is needed at the top or bottom shaft end. This arrangement also requires additional space for the pulleys above or below the cabin. Furthermore, only cables - usually steel cables - can be used as the suspension means, since the support means must be bent at least twice by 90 ° about the cable axis. In addition, more than two support means are required to accommodate large loads. The known system always needs a counterweight. As a result, additional space in the shaft cross section is required. Such a drive device is complicated, complicated and thus very expensive to manufacture.

At the elevator after the US Pat. No. 6,035,974 is the drive motor with the horizontal drive shaft above the elevator platform and the support means extend on both sides of the opposite side parts of the elevator platform. For the arrangement of the guide system, the suspension means and the two counterweights a lot of space is required. The arrangement of access to the long sides of the platform is excluded.

From the document mentioned in the search report JP 2000143132 It is known that a Zugmitteleinrichtung for an installable in a shaft scaffold lift system, which can be arranged free-standing and / or in a lift shaft and serves to receive a lifting device, which via at least one connected to at least one drive motor mounted on the shaft frame drive shaft by means of support means, in particular a traction means, is moved up and down the shaft frame.

The Zugmitteleinrichtung is intended to be equipped as a pulley, in particular factor pulley with two or more, in particular four, deflectors whose axes are arranged on an approximately vertical plane with each other, wherein at least one deflection pulley in the shaft or on the shaft frame above the elevator system, another Deflection disk below the elevator installation in the lift shaft or on the shaft scaffold and one or more, in particular two deflecting disks, are mounted on the side element of the load suspension device, in particular the travel platform.

Furthermore, an anchorage for the traction means of the flat pull in the lift shaft or on the shaft frame above the elevator installation and a further anchorage for the traction means of the flat pull shall be connected below the elevator installation to the anchorage in the service shaft or at the shaft scaffold

The known arrangement according to D1, however, lacks an important combination feature, namely: "that at least one drive shaft extends approximately horizontally between two diagonally opposite corner regions of the shaft framework".

It should also be noted that the known arrangement according to D1 contains no indication that the anchorage for the traction means of the flat train in the lift shaft above the elevator installation and a further anchoring for the traction means of the flat train below the elevator installation to the anchorage in Chassis is connected. Both anchors are connected to a shaft scaffold frame, which makes the system more expensive because of the cost of materials.

The invention has for its object to produce the shaft scaffold and the associated elevator system in a simple and cost-effective manner with optimal space utilization.

The object is achieved in that at least one drive shaft extends approximately horizontally between two diagonally opposite corner regions of the shaft framework and is directly or indirectly connected to opposite parts, in particular with longitudinal sides of the shaft framework or wall parts of the driving shaft and in the region of its two ends each having a drive pulley, which moves with the help of a respective suspension means the load-receiving means and downwards. As a result, sufficient free space for the load-receiving means, which can be designed as a driving platform, is created in a simple manner. This is also achieved in that the drive shaft extends approximately horizontally through the shaft frame and has in the region of its two ends depending on a drive pulley, which moves by means of a respective suspension means the load-receiving means and down. Since the support means, the guide system and all other technical components are provided exclusively in the corner of the shaft frame, a very large clearance is created in the central region of the shaft frame for the load-carrying means, in particular for the driving platform.

For this purpose, it is advantageous that the cross section of the shaft frame is round, oval, polygonal, preferably square and the ends of the drive shafts associated support means in the immediate vicinity and parallel to at least the corner regions forming vertically extending longitudinal sides of the shaft frame. For this purpose, advantageously, the corner regions of the driving platform, which are adapted to the inner cross section of the shaft framework, cut off, so that created by the two converging in the corner longitudinal sides of the shaft frame and the opposite end edge of the traveling platform, if this has a rectangular or square base, a triangular in the view from above free space in which the support means, the guide system and the brake system can be accommodated optimally for the driving platform. Since the triangular area requires very little space to place the suspension elements at this point, the access openings to the driving platform are also optimally enlarged. Overall, you get in the smallest space optimal space utilization for the required technology of the entire system. In this way, more than 70% of the installation surface of the system can be made available for the driving platform. The use of a square platform also greatly simplifies the planning of an architect, since he can easily integrate such a building in a building. In addition, an optimal access to the driving platform is created by the device according to the invention on all four sides at all stops. For the use of the elevator system by a wheelchair user, the square basic shape of the platform provides an optimal turning possibility. This movement takes place in a circle, so that the beveled corners of the cabin walls are not needed.

For this purpose, it is advantageous for a drive shaft or two drive shafts aligned coaxially to one another to extend between the oppositely lying corner regions of the shaft framework and to be in operative connection with the drive motor, or for each drive shaft to be operatively connected to one drive motor each. The drive shaft may advantageously be formed as a one-piece continuous drive shaft or in two parts or may also be provided two drive shafts. Advantageously, the one-piece drive shaft is supported at its two outer ends on the shaft frame or on the walls of the driving shaft. The drive shaft is divided into two parts, it can be supported on the outer end of the shaft frame or on the walls of the driving shaft and with their inner ends on one in the upper part of the Shaft stand arranged Traverse support, which also serves to accommodate the drive motor. As in the two opposite corner areas a space is created, as already mentioned, the support means with the associated deflecting or traction sheaves, the guide system of the driving platform and in the corner or in the framework corners of the shaft framework can be advantageously and space-saving. Furthermore, this measure also ensures that the bending moments acting on the drive shaft can be kept very small, so that the drive shaft does not need to be dimensioned as strongly as before. As a result, material costs can also be saved.

An additional possibility, according to a development of the invention, that the drive motor has an output shaft whose axis of rotation is arranged approximately at right angles to a rotational axis of the drive shaft of the support means, in particular traction means. This gives optimum space utilization for the drive units.

Furthermore, it is advantageous for the load-receiving means to be a traveling platform which has at least two side elements which are upright in the end edge region and / or in the corner region of the driving platform and which are connected to the suspension elements.

It is also advantageous that the suspension element is arranged between side elements of the traveling platform and the corner region forming longitudinal sides of the shaft framework. The advantageously placed side elements allow optimally large passage openings on all four sides of the drive platform. At the same time, they also serve as a protective device, since they cover the support means provided in the corner regions and protect persons located on the load-carrying means, in particular the traveling platform, since they prevent them from coming into contact with the suspension elements.

It is also advantageous that the Zugmitteleinrichtung is designed according to the principle of a pulley and has one or more deflection pulleys and all axes of the deflection plates are arranged approximately on a vertically extending plane with each other. As a result, in a simple space-saving manner, the pulley can be accommodated in the corner area of the traveling platform and shaft frame.

Of particular importance for the present invention that for the Zugmitteleinrichtung, in particular the pulley, chains, steel cables or timing belt can be used as traction means. The traction means are fixed only with releasable clamp holders in the end positions, so that the previously necessary counterweights can be dispensed with in a space-saving and cost-saving manner. The use of timing belts has the advantage that they do not stretch even after prolonged use, have no slippage and can be used quietly. Furthermore, timing belts are resistant to various environmental influences such as very high or low temperatures, sunlight, moisture, etc. and do not need maintenance.

Furthermore, it is advantageous that the pulley has a transmission ratio of 1: 1, 2: 1, 3: 1, 4: 1, 5: 1 or greater. The advantageous use of a pulley with the appropriate gear ratio and the execution of a weight-reduced lifting device in the form of a platform, consisting of a bottom and a peripheral frame, also make it possible to dispense with counterweights and still keep the drive power low. With an outside dimension of the driving platform of approx. 1.4 x 1.4 m and the corresponding gear ratio of 2: 1, a low driving speed and the low mass of the driving platform, the drive motor achieves a drive power of only approx. 2 kW. Advantageously, a frequency control can be used and thereby generates the three phases required by the drive, via the frequency control and the Starting current can be reduced. The elevator system can thus be connected to conventional sockets.

It is also advantageous that the load-receiving means, in particular the traveling platform, is guided in the shaft frame by means of at least one guide, in particular a guide rail arranged on the shaft frame, the guide being at least in a corner region of the shaft frame and / or in the immediate vicinity of the suspension element, in particular the pulley, is arranged.

Furthermore, it is advantageous that the drive motor is arranged with the drive shaft in a shaft head of the shaft framework or in a shaft pit.

An additional possibility is, according to a development of the invention, that the upright side elements of the driving platform are arranged in the corner region of the driving platform such that a free access opening to the driving platform is present on at least four sides. In this way, a shaft scaffolding designed in this way can be easily erected with the traveling platform adapted to the shaft scaffolding also free-standing on existing buildings or can subsequently be integrated in the building without major alterations.

It is also advantageous that one or more access openings on the platform can be closed by means of cabin walls and / or doors.

If desired, the access openings on the drive platform can be provided with a cabin wall when not needed. There are no higher demands on the strength of this cabin wall. The cabin wall can be filigree, so that a glass wall can be executed.

If the cabin walls are omitted, or if these are made of glass, and the shaft framework is further provided with glass cladding on all sides, creates an architecturally appealing execution with a maximum possible transparency.

According to another embodiment, it is advantageous that the shaft frame consists of at least two diagonally opposite, vertically extending posts on which the support means, guide rails and at least one upper and one lower deflection plate are arranged directly or indirectly and that the shaft frame and / or diagonally opposite, vertically extending posts and / or the traverse in the corner region of the shaft framework is medium or directly connected to at least one inner wall of the driving shaft. This gives a very inexpensive elevator system that can be easily installed in a lift shaft.

A cost saving can be achieved also by the fact that the guide rails are attached directly and / or with the aid of a bracket to the shaft walls or on the inner wall of the driving shaft.

It is also advantageous that the suspension element, in particular the toothed belt, is bent only in one direction in all deflecting disks. As a result, the toothed belt also needs to be provided with teeth on only one side, so that the service life of the toothed belt can be substantially increased. Instead of the toothed belt, as already mentioned, also differently trained traction means z. B. V-belts are used.

Further advantages and details of the invention are explained in the patent claims and in the description and illustrated in the figures.

In the drawing, a well structure 102 is shown for an elevator installation 103, which can be arranged free-standing or in a drive shaft 100. In the hoistway 100, the shaft framework 102 can be arranged free-standing or be supported by means of connecting elements not shown in the drawing side walls of the driving shaft 100.

According to Fig. 2a a floor ceiling 116 is supported on a lower section 104 of the shaft frame 102. For this purpose, there is an opening 118 in the floor ceiling 116, through which the load receiving means, in particular a traveling platform 200 (FIG. Fig. 4 ) by means of suspension elements 208 ( Fig. 4 ) is moved vertically up and down. The lower section 104 of the shaft frame 102 stands with the aid of adjustable feet 112 in a shaft pit 114.

An upper section 106 of the shaft frame 102 is located above the floor ceiling 116 and is referred to as shaft head 124. In this section after the in Fig. 2a Shown embodiment, the drive assembly with a drive motor 126 and a transmission, in particular worm gear 125, is shown. The drive motor 126 with a drive shaft 204 can be arranged in the shaft head 124 of the shaft frame 102 or in the shaft pit 114.

The upper section 106 of the elevator shaft frame 102 is arranged on the floor ceiling 116. In this way, the shaft frame 102 from floor to floor or, with a correspondingly large opening, as a continuous construction to be ordered. An entire shaft frame height 120 can span several floors, with a delivery height 122 can also be more than three meters.

According to Fig. 1 is in the shaft frame 102, a load-receiving means, in particular a driving platform 200, arranged vertically movable. The cross-section of the shaft frame 102 and / or the load receiving means, in particular the traveling platform 200, is oval or polygonal, preferably square.

The load-receiving means 200 or the drive platform of square design in the exemplary embodiment has at least two in the end edge region and / or in a corner region 105 of the travel platform 200, two diagonally opposite upright side elements 202, which are connected to support means 208. The suspension element 208 can be a cable arrangement or a pulley arrangement operating on the principle of a pulley 209.

With the help of the pulley 209, the amount of force to be applied, z. For moving the elevator load. The pulley consists of fixed and / or loose pulleys or rollers and a traction device or a rope. The toothed belt train follows the same principle, except that a toothed belt is used instead of a rope. In the cable pull or pulley 209 used here according to the invention two fixed anchors 216 and 218 are used. However, the decisive factor is always the number of load-bearing ropes on which the load is distributed. In the illustrated basic form of the pulley tension σ is the same at each point of the rope. The weight F _{L of} the mass is therefore evenly distributed to all n- connections between the lower and upper rollers and the supporting ropes. The tensile force at the end of the rope is proportional to the tension in the rope and thus: F _z = F _l / n = mg / n.

The pulley 209 according to the invention may have a transmission ratio of 1: 1, 2: 1, 3: 1, 4: 1, 5: 1 or greater. In this way, among other things, a counterweight can be dispensed with.

The two diagonally opposite side elements 202 are connected to one another at their upper end via an upper cross member 203. Apart from the two diagonally opposite side elements 202, the load-receiving means, in particular the traveling platform 200, has no further side parts. In this way one obtains four free access openings 128. According to another embodiment according to Fig. 6 can the driving platform next to the two side elements 202 additional z. B. glass, metal or formed from a plastic material side walls.

The load-receiving means, in particular the traveling platform 200, is with the aid of at least one guide, in particular a guide rail 220 arranged on the shaft frame 102 (FIG. Fig. 7 ), guided vertically in the shaft frame 102. The guide is at least in a corner region 105 (FIG. Fig. 5 ) of the shaft frame 102 and / or in the immediate vicinity of the suspension element 208, in particular of the pulley block 209.

The support frame 202 is provided for this purpose with vertically extending depressions having guides 222 which on the support frame 202 or on the side member 202 arranged guide rail 220 (FIGS. Fig. 7 ) are guided. If the suspension element 208 or the drive axle breaks, an emergency brake device 224 is automatically activated, which is fixed to the support frame 202 ( Fig. 7 . 9 ).

In a square, rectangular load-receiving means, in particular the driving platform 200, the corner edges of the driving platform are cut off, so that the front edges of the driving platform 200 with two adjacent, converging in a corner longitudinal sides 109, 111 and 113 and 115 with the opposite, oblique front edge the driving platform 200 form a triangular cutout ie the corner region 105, which has chosen so large is that the support means 208 can be accommodated in the free space. The other cross-sectional shapes are handled in a similar way.

How out Fig. 1 and 5 As can be seen, the drive motor 126 is arranged on a traverse 127 which is located in the upper shaft head 124. The traverse 127 is disposed between the two diagonally opposite corner portions 105 of the shaft frame 102 and connected thereto. However, it is also possible to firmly connect the traverse 127 with the corner regions 105 of the wall elements of the driving shaft 100. At least one horizontally extending drive shaft 204 or two horizontal drive shafts are connected to the drive motor 126 with the aid of the worm gear 125. Between the opposite corner regions 105 of the shaft frame 102, a drive shaft or two coaxial with each other aligned drive shafts 204 may extend, which are in operative connection with the drive motor 126. Furthermore, it is possible for each drive shaft to be operatively connected to one drive motor each. Also, the drive motor may be arranged at any other angle to the drive axle or the drive axles or at a distance from the drive axle.

The traverse 127 and the drive shaft 204 intersect each other at right angles and thus extend in each case into the opposite corner regions 105. As already mentioned, they are firmly connected to the shaft frame 102 or to a wall of the driving shaft 100 or stored there. By connecting the traverse 127 and the drive shaft 204 on the shaft frame 102, the torsional stiffness of the shaft frame 102 is substantially improved.

The drive motor 126 has an output shaft whose rotation axis 117 is arranged approximately at right angles to a rotation axis 119 of the drive shaft 204 of the suspension element, in particular traction device 208.

The support means 208 associated with the ends of the drive shafts 204 extend in the immediate vicinity of and parallel to the vertically extending ones forming the corner regions Longitudinal sides 109, 111, 113, 115 of the shaft frame 102 and / or to a longitudinal center axis 107th

Furthermore, each one support means 208 is arranged to save space in the two diagonally opposite corner regions 105. The suspension elements 208 are each provided between a side element 202 of the traveling platform 200 and the approximately triangular-shaped corner region 105 forming longitudinal sides 109, 111, 113, 115 of the shaft frame 102 or the walls of the driving shaft 100.

The shaft frame 102 consists of four perpendicularly oriented, vertically extending longitudinal sides 109, 111, 113 and 115. Each longitudinal side 109, 111, 113 and 115 consists of a rectangular frame with posts or longitudinal struts 129, which are connected to one another via a plurality of cross struts or latches 201 can be firmly connected. Depending on the embodiment, the central transverse strut 201 can be dispensed with so that each longitudinal side 109, 111, 113 and 115 also has a free access opening 128 to the load receiving means, in particular to the traveling platform.

In the embodiment according to Fig. 1 the access opening 128 is closable by means of a pivotable door 123. Likewise, one or more access openings 128 can be closed by means of a shaft lining wall or a door 123. The door 123 is advantageously arranged on the shaft frame 102. But it can also be arranged additional doors on the platform or platform on a driver's cab, not shown here.

The traveling platform 200 is preferably of square design and the support means 208 associated with the ends of the drive shafts 204 extend in the immediate vicinity of and parallel to the vertically extending longitudinal sides 109, 111, 113, 115 of the shaft structure 102 forming the corner regions.

The Zugmitteleinrichtung 208 operates on the principle of a pulley and is therefore hereinafter referred to as pulley 209. It has one or more deflection pulleys 206, 212, 214, 219.

The support means 208 arranged on both sides of the travel platform 200 run from the end suspension or anchoring 216 provided in the shaft head 124 to the wall of the drive shaft 100 or the shaft frame 102 via the deflection disk 212 to the drive pulley 206 and from there further via the shaft 104 located in the shaft pit or on the wall of the driving shaft 100 or on the shaft frame 102 by means of anchoring 218 fixedly connected deflecting plate 219. From there, the support means 208 continues over the disposed on the side member or support frame 202 deflecting 214 for final suspension or anchoring 218, either on the shaft frame 102 or is secured in the shaft pit 114.

The drive pulley 206 and the individual deflection disks 212, 214, 219 all have the same diameter, so that no different bending loads of the suspension elements occur. The support means 208 are bent only in the same direction, ie, they are not subject to bending but only a constant deflection. In the exemplary embodiment, the support means 208 are all bent in the clockwise direction. Viewed from the end suspension 218 in the direction of the floor ceiling 216, the suspension element experiences in Fig. 7 only a right bend. So that the support means do not rub against each other, z. B. the deflecting plates 212, 214 slightly opposite to the drive pulley and the fixed pulleys 219 according to Fig. 8 slightly laterally offset.

All axes of the drive pulley 206 and the pulleys 212, 214, 219 are according to Fig. 7 arranged approximately on a vertical plane with each other. As a result, in a simple space-saving manner, the pulley can be accommodated very well in the corner region of the travel platform 200 and shaft frame 102. The drive pulley 206 or the deflection pulleys 212, 214, 219 may, for example, be groove-shaped traction sheaves, chain pinions or toothed belt pulleys.

The representation according to Fig. 9 shows a schematic side view. The suspension elements 208 pass over the drive disks 206 attached to the ends of the drive shaft 204 to the deflection disks 212, 214 of the deflection disk in the shaft pit 219 and to the end suspensions 216 and 218 located on the support frame 202. The suspension elements 208 used can be, for example, steel cables with and without plastic sheathing , Timing belts or steel chains.

The drive pulley 206 or the drive shaft 204 (FIG. Fig. 7 ) connected drive pulley 206 is in the lift shaft 100 or in the shaft frame 102 in the region of the shaft head 124 ( Fig. 2 ) stored above the driving platform 200. Another deflecting plate 219 is mounted below the elevator installation 103 in the section 104 in the driving shaft or on the shaft frame 102. One or more, in particular two, deflecting disks 212, 214 are mounted in or on the side elements 202 of the driving platform 200.

The anchoring 216 for the traction means 208 of the pulley system 209 is in the elevator shaft 100 or on the shaft frame 102 above the elevator installation 103 and another anchoring 218 is connected to the traction means of the flat fence 209 below the elevator installation 103 in the elevator shaft 100 or in the shaft structure 102.

The anchoring 218 may according to Fig. 9 each two by means of bolts held together flat pieces 221, 225, of which the flat piece 225 has a toothing. Between the flat pieces 221, 225, the support means 208 can be clamped. In this way, a bias of the traction means is achieved.

According to a further embodiment according to Fig. 10 may differ from the embodiment according to Fig. 1 or 5, the shaft framework 102 from at least two diagonally opposite, vertically extending in cross-section rectangular posts 226 exist. The posts 226 can due to their Rectangular cross-section very well in the corner region 105 of the shaft frame 102 may be directly or indirectly connected to at least one inner wall 227 of the driving shaft 100 and additionally stand on the floor of the driving shaft 100. It is also possible to dispense with the posts 226 if the guide rails 107 with holders 230 are fastened directly to the chess walls or to the inner wall 227 of the driving shaft 100. '

Furthermore, the traverse 127 in the corner region 105 of the shaft frame 102 may be directly or indirectly connected to at least one inner wall 227 of the driving shaft 100 and, in particular with the aid of a holder 229, be attached to the inner wall 227 to save space.

The rotation axis 117 of the drive motor 126 and the rotation axis 119 of the drive shaft 204 close in accordance with Fig. 5 and 10 an angle α of 90 °. However, if the cross-sectional area of the shaft frame 102 or the driving shaft 100 has a cross-sectional shape deviating from the rectangular cross-section, the angle α may be larger or smaller than 90 °.

According to another Aufrührungsbeispiel according to Fig. 11 For example, the guide rails 102 can be fastened directly and / or with the aid of a holder 230 in the corner region 105 on the shaft walls or on the inner wall 227 of the driving shaft 100. Like from the Fig. 5 and 11 shows, the guide rail 102 is formed as a T-rail and the rail foot with the shaft walls or with the inner wall 227 of the driving shaft 100 firmly connected. The rail web of the guide 222 embodied as a T rail serves for displaceable reception of the guide 222 arranged on the support frame or side element 202.
