    FIELD OF THE INVENTION The present invention relates to a device and a set for simplified and rapid assembly and fixing of a so-called spindle unit, inside a telescopically extendable leg.
    The spindle unit is provided with an angular shaft, which through, for example, a motor or a crank, transmits a rotational movement from one gear to another gear, which affects a gangway or the like, which is a central part of the spindle unit. By mounting such a complete spindle unit inside a telescopically extendable leg, it becomes possible to transfer a rotational motion to a linear motion to affect the length of the telescopic leg.
    The invention is used in the assembly of said complete spindle unit in a telescopically extendable leg, which leg is primarily intended to be used in combination with a hOj and submersible disc, such as at a desk or the like, but is also applicable to other types of hOj - and collectible boards such as boards for coffee tables, coke banks, coke ovens and more. For the sake of simplicity, the invention is exemplified hereinafter in relation to a height-adjustable desk.
    Background of the Invention A standard model of a complete height-adjustable desk usually consists of a number of main components such as a table top, two complete telescopically extendable legs, one foot per leg, a beam or beam frame that connects the two legs to a stand / base, at least one side bracket per leg, which fixes the table top to the respective leg / base and at the same time braces up the complete desk, and some form of drive device for effecting raising / lowering of the table top, for example a motor or a crank. In addition, a larger or smaller amount of other parts or accessories that may be present depending on how advanced the model is! as Onskas. Due to the fact that a fully assembled desk is bulky, the table top, any side braces, the complete telescopically extendable legs, any crossbeam or frame as well as killer etc. are delivered as loose parts, which are assembled into a complete desk on site at the end customer.
    In the field of height-adjustable tables or boards, there are several different techniques for achieving the installation of the height of the table. There are, for example, scissor solutions, but the most common on the market today are solutions with telescopically installable legs, which are usually connected in pairs to a common table base, on which the table top is placed. The telescopic movement refers to a linear movement which can be achieved by, for example, a gas spring or the use of a so-called complete spindle unit. 1 Gas spring solutions are completely dominant bile shark and submersible chairs, but for tables or boards it is more common with different "spindle solutions". The present invention relates to the latter. A spindle unit consists, for example, of a threaded rod or screw also called a spindle, enclosed by a housing of some shape, such as a square tube or a round tube. The tube has at its upper arid a nut where the gangway is screwed through and thus the threaded rod is rotatable in the housing and screwed out of or into the housing to achieve a linear movement. At the top of the spindle unit, some type of gear is arranged, usually a so-called angular gear. This angular axis can look different, but the function meant that a rotational movement in one joint - for example around a horizontal axis - is transmitted to a rotational movement in another joint, often perpendicular to the first axis - for example around a vertical axis.
    In this way, a user of a height-adjustable bard can use, for example, a crank to transfer the crank movement to a linear movement of the telescopically extendable leg (s). The legs are weirdly interconnected so that a rotational motion has the crank transferred to [ada legs at the same time. Alternatively, a motor drive is used to accomplish the same.
    A common type of table leg of the telescopic type in connection with height-adjustable desks consists of two or more rudder parts of different dimensions, which are arranged to interlock, and the placement of the complete spindle unit including the angular shaft is made inside the telescopic leg.
    In a type of utility, for example, a desk is attached, the upper part of the spindle unit is fixed in the upper rudder part and its lower part in the lower rudder part, and a rotation of the gangway at one hall projects so that the razor parts freeze, with the leg extended and vice versa. In hitherto known solutions, the assembly of the complete spindle unit takes place by forcing the spindle unit with the paired gear into the rudder parts and then anchoring it by means of a screw connection. In the Upper Spirit, the force effect on the fastening takes place in several dimensions, so this fastening must be strong and can, for example, consist of fitted welded plate angles inside the Upper Spirit for standing and steering the angular shaft and a number of screws anchoring the angular shaft in the Upper tube part. Since the angular shaft itself does not comprise any threaded screw tail for the screw thread connection, for example a special plate must first be fixedly fixed between the angular shaft and the spindle unit, which plate then comprises the threaded tails used in the danger ring to the upper rudder part. In the lower end of the lower rudder part there is usually a fitted welded bottom plate with a centrally located hall in which the lower end of the spindle unit is fixed with a screw. All in all, existing solutions for mounting and fixing the complete spindle unit to the telescopically extendable leg included a number of details and steps such as fitting flat angles, mounting an extra screw plate and handling and mounting a number of screws at the spindle unit's upper end cavity as at its lower end. which affects both production cost and the time for assembly to a 2 complete telescopic leg.
    Disclosure of the Invention The present invention achieves the object of simplifying and shortening the assembly time and thereby obtaining a lower production cost in the production of telescopically extendable legs for primarily heatable and submersible discs, preferably for desks. From the first aspect of the invention the object is achieved in that a device of the initially specified type comprises at least one welding device, which is arranged to weld the complete spindle unit inside the telescopically extendable leg by a "self-lasing" function. Preferably this is done by the complete spindle unit being snapped / clicked on while the complete spindle unit is mounted inside the leg and arrives at a dedicated end layer in the leg. For example, the welding device (s) may be a special detail arranged at the complete spindle unit or, for example, a part of the angular shaft or its housing. For products in large series where one and the same type of angular shaft is used for one and the same telescopic leg, it may be a good idea to develop a specially adapted angular shaft where the welding device is part of the angular shaft. In other cases, it may be most advantageous to use special details arranged with welding devices. Furthermore, the laser device can also be a part of the bone or a special detail of the bone, which engages with the complete spindle unit and lasers it to the bone through the snap function / click function. Through a welding device arranged for snapping, the assembly is very fast and smooth compared to the solutions on the market.
    According to a preferred embodiment, the device comprises a first adapter which is arranged to hold and fix the angular shaft mounted on the spindle unit, to the upper end of the upper rudder part of the telescopic leg. This is made possible by the adapter comprising a receiving space, adapted to hold and fix the angular shaft, and for at least parts of the outer mat of the adapter housing to be mated with the inner mat of the upper part, in which the adapter together with the spindle unit is insertable. By means of this device the adapter is controlled during its insertion in the upper rudder part and furthermore the angular shaft is also fixed so that it cannot be rotated, in that it is the hall of the adapter which in turn is controlled by the upper rudder part. Furthermore, the housing of the adapter comprises at least one resilient first tongue, but preferably two or more, resilient first tongues. The tongue "" lives "in principle with the outer mat of the housing, but also comprises at least one wedge-shaped first welding lug, which has its pointed side closest to the insertion direction of the adapter, i.e. extends from a level at the outer mat of the housing and out to a level outside the housing. outer mat and terminated with a sharp welding edge to prevent movement 3 in the direction of insertion. the upper rudder part, the resilient first tongue snaps out to its resting position again, in that the upper rudder part has a welding instruction in the form of a recess in the groove cradle, which recess is arranged for the welding lug of the tongue, respectively. of the telescopic leg whereby the adapter cannot be moved in the longitudinal direction of the leg. The shape of the adapter can of course also be designed as an adapter which is mounted on the outside of the upper part. In the same way, the adapter then comprises a receiving space arranged to hold and fix the angular shaft, but the control of the adapter and the welding through the resilient tongues takes place so as to say from the outside because the resilient tongues spring out when the adapter is fitted, then snap into the recesses and lock the adapter against the upper rudder part. Through the first adapter it is therefore possible to mount and fix the complete spindle unit including angular shaft in the telescopic leg without having to weld special plate angles on the upper rudder part, without having to mount an extra screw plate between spindle and gear and also avoid handling and using a multiple screws, which age glazing requires. The adapter is simply pushed into the tube until it snaps into place, which is an assembly advantage and simplification compared to older loads.
    According to a preferred embodiment of the invention, the housing of the first adapter comprises a welding space arranged behind the respective resilient tongue. The locking space is a cavity which is sufficiently wide / deep to allow the resilient tongue to spring when the adapter is mounted in the Owe rudder part. When the adapter has then arrived at its final position and the welding lug (s) have snapped into the recesses in the cradle of the upper rudder, the resilient tongue is back in its resting position, whereby the welding space 'Ater's retains its original size. The welding space is further arranged to receive a welding tray, which, after the adapter has snapped into the upper part, is inserted into the welding space with its entire length. Thus, the load space is at least almost completely occupied by the load washer, the resilient tongue being prevented from being lowered and thus the adapter being completely secured in the upper tube part, which means that the complete spindle unit including angular gear is at least as securely mounted as older solutions screwed . The advantage is, as previously mentioned, that the assembly can take place through a common movement where the spindle unit with adapter and load washers is pushed into the telescopically extendable leg and secured there, without handling and mounting a number of screws. The load washers are in a first layer slightly tucked into the load compartment, sufficient to be in place when mounting through a movement, but no longer inserted than the resilient 4 tongue can spring. As mentioned, the load washers are pushed in when the adapter snaps into the upper part.
    According to a further dangerous form of access, the first adapter comprises a screw plate, which is fixedly arranged in the adapter through all of it which is inserted into a spar intended groove in one of the housing cradles of the adapter. The screw plate is preferably a plate of metal, which comprises a pair of threaded slides. When the adapter is mounted and secured as previously described, through a screw connection between the upper rudder part of the telescopic leg and the screw plate, a good stability and half-strength can be achieved, the cla adapter including spindle unit and angular shaft is screwed into the upper rudder part, which is prepared to the screwdriver.
    According to a preferred embodiment, the device comprises a so-called side bracket, which is partly arranged to be screwed into the table top and partly into the screw plate. This connects the table top to the base but also ensures that the adapter is further fixed to the leg because, instead of having to screw the adapter directly into the leg as in the embodiment above, cla side bracket is mounted to the leg, the screw is also tightened in the screw plate integrated in the adapter. This achieves good stability and the half-strength cla adapter, including the spindle unit and angular shaft, is screwed into the telescopic leg. This is done so that the saw during the final assembly of the desk when the base is connected to the table top. In previous solutions, the mounting of the side strut only meant a fixation of the same, but did not further contribute to the fixation of the complete spindle unit, as the latter was done in a separate step.
    According to a further dangerous embodiment, the first adapter comprises a cantilever at its upper edge, which in the mounted end layer of the adapter rests on the upper edge of the carrying part.
    This stop prevents the adapter from disappearing into the upper rudder part during assembly, as the welding lugs would not come into engagement with the recesses in the rudder. When the assembly goes according to plan and the welding lugs engage with the recesses, an upward movement of the adapter is prevented by the welding lugs and at the same time the edge of the upper rudder part together with the cantilever stops the adapter from a downward movement, the adapter being fully loaded in the longitudinal direction of the leg. The advantages over older solutions are that the exact fixation of the adapter longitudinally in the upper part goes all the later mounting goes smoothly because the adapter is in place and in exact age the mounting of the side bracket or screw only gets the locks that do not have the side bracket.
    According to a further preferred embodiment, the device comprises a second adapter which is arranged to hold and guide and fix the lower spirit of the spindle unit, to the lower spirit of the lower rudder part of the telescopic leg. This is made possible by the fact that the second adapter is fixedly arranged to the lower part of the spindle unit and that it comprises at least two resilient second tongues, respectively arranged with a wedge-shaped second welding lug. Upon insertion of the spindle unit into the telescopically extendable leg, the welding lugs, through their wedge shape, will guide the lower spirit of the spindle unit into a second welding instruction intended for that purpose. This second welding instruction is fixedly arranged inside the lower spirit of the lower rudder part. When the spindle unit is mounted in the telescopic leg, the second welding guide will, by its design, press the resilient second tongues out of its resting position as the wedge-shaped second welding lugs pass through the second welding guide. After the welding lugs have just passed with their wedge-shaped body, they spring out again, the second adapter saying that the saw snaps into the second welding instruction by terminating the wedge-shaped second welding lugs with a sharp edge and thus the lower end of the spindle unit is fixed to the telescopic extendable leg. As previously mentioned, older solutions only have mounting with a screw or the like for fixing and fixed mounting of the lower part of the spindle unit to the telescopically extendable leg. The present invention loosens the assembly by a simple snapping while the spindle unit is inserted into the leg to a final layer, whereby the complete spindle unit is snapped onto an assembly which is customary and secure.
    According to a preferred embodiment of the embodiment just mentioned above, the second adapter also comprises snaps which are arranged for snapping a foot part to the telescopically extendable leg. This makes it easy to quickly and easily mount a foot to the leg on site at the customer's or at the assembly line. Preferably, the snap fitting is supplemented with additional securing for good hall strength, for example by screw connections between the second adapter and the foot part.
    From the second aspect of the invention, the object is achieved by a method of mounting and fixing the spindle unit fitted with the angular shaft inside the telescopically extendable leg. The main object of the invention is to facilitate the assembly and thereby reduce the assembly time and also the cost of the end product. This is achieved by forcing the spindle unit provided with the angular shaft into the telescopically extendable leg in a mounting moment until it reaches an end layer in the leg, whereby it is automatically attached to the leg by preferably snapping or clicking. This is a considerable advantage during assembly compared to older solutions where everything is screwed on in different steps. Now the complete spindle unit is simply snapped into the leg in a quick and easy way in one motion. According to a preferred embodiment, the object is achieved by providing the spindle unit with the angular shaft with the first adapter and the second adapter as described above. These are pre-assembled on the spindle unit in a first pre-assembly step. The complete spindle unit is mounted during assembly into the telescopically extendable leg, which consists of at least two tube parts, one upper and one lower, where the lower one runs inside the upper tube part. Because the adapters and the upper rudder part and the lower rudder part are arranged as described above, clearly described as the first adapter is arranged to be in and snap into the first reading instructions of the upper rudder part and the second adapter is arranged to be in and snap into a second welding instruction in the lower rudder part, it becomes possible to permanently mount that spindle unit inside the leg through a single mounting step. The complete spindle unit is simply pushed inside the leg and pushed in until it snaps into its upper and lower spirit at the same time, when the spindle unit reaches its final position. The end layer for the bearing of the complete spindle unit in the telescopic leg is given by the first and second welding instructions, but an advantage is also that the first adapter at its top edge includes a cantilever, which stops the insertion of the complete spindle unit at the end layer. This makes it impossible, if the assembly were to take place in the wrong way, to straighten the complete spindle unit too far into the leg. Older solutions are based on the spindle unit with angular shaft being provided with some form of screw plate or the like, in which the angular shaft and thus the spindle unit can be anchored by screwing in the telescopic leg. According to prior art, the upper rudder part and the lower rudder part are also provided with different guiding angles which are welded firmly inside the rudder parts and which have the angular shaft and the lower part of the spindle unit inside the rudder parts. A number of screws are then used to secure the spindle assembly to the leg. With the present invention a quick, simple and simple assembly of the spindle unit in the telescopically extendable leg is obtained with fewer details and steps to handle.
    According to a preferred embodiment of the invented method, the assembly step is supplemented with a securing element, which in practice takes place in principle in the same motion as the assembly of the complete spindle unit. The first adapter, which is arranged to partly hold and fix the angular shaft and the spindle unit at the upper tube part of the telescopic leg, also comprises, according to the preferred embodiment, two locking spaces behind the respective resilient first tongue. This locking space is a prerequisite for the resilient first tongue to be able to spring, that is to say in this space the free spirit of the resilient first tongue is pressed in during the installation of the spindle unit / the first adapter in the leg. At the top of the adapter's load space, a load plate is inserted for a short distance and the load plate in some layers does not affect the load space. But during the final phase of installation, when the complete spindle unit, including the adapters, reaches its final position at night, the load washer 7 is pushed into the load compartment, which load tray thereby fills the load compartment and prevents the resilient tongue from springing back and thus leaving the load layer. This step can, as mentioned above, in principle take place in the same movement as the installation of the complete spindle unit in the leg, as for example a fitter or a robot inserts it into the tube and pushes it into place and also pushes the load washers into the load compartments as soon as the finish is reached.
    The invention is further explained by the following detailed description of embodiments of the invention with reference to the accompanying figures.

    Detailed description of the figures Fig. 1a shows a spindle unit 2 provided with an angular shaft 1, where the spindle unit 2 in this case consists of a walking rod 32 enclosed by a spindle housing 33. A first adapter 8 is arranged for the top of the spindle unit 4, which is mounted in connection in that the angular shaft 1 is mounted to the spindle unit 2 in a pre-assembly step A. The first adapter 8 is arranged to hold and fix the angular shaft 1 in its mounted bearing to the spindle unit 2, but this is further explained in connection with Figures 2a-2c. A second adapter 24 is arranged for the lower end 25 of the spindle unit 2 in the pre-assembly step A. This can preferably be pressed into place in the lower part of the spindle housing 33, after which, for example, a sprain of the spindle housing 33 cracks the second adapter 24 in the spindle housing 33. -4c. Fig. 1b shows how the mounting of the complete spindle unit 2, including the pre-assembled first adapter 8 and the second adapter 24, is done by inserting the complete spindle unit 2 inside a telescopically extendable leg 3 in a mounting step B. The leg 3 consists of at least two rudder parts, an upper rudder part 6 and a lower rudder part 7, where according to the dangerous embodiment the lower rudder part 7 can lap in the upper rudder part 6, the leg 3 being set at an adjustable length. At the assembly step B, the complete spindle unit 2 is moved into the leg 3, until a spindle unit 2 arrives at a final layer where it is to be secured to the leg 3. An upper edge 21 of the Mesta adapter 8 will then rest on an upper edge 23 of the upper rudder part. 6, and at the same time the first adapter 8 arrives at its final layer 14, in which it snaps into two first welding instructions 15. This is explained in more detail in Figures 2a-c and 3a-b. The second adapter 24 also snaps into a second welding instruction 28 (not shown) arranged in the lower rudder part 7, which is explained in more detail in Figures 4a-c.
    Figs. 2a-2c show different views of the first adapter 8. According to the preferred embodiment, the first adapter 8 comprises a housing 10, which encloses a receiving space 9.
    Said receiving space 9 is arranged to hold and fix the angular shaft 1 in such a way that the shape of the housing 10 and thus also the shape of the receiving space 9 fits the outer mat of the angular shaft 1, the angular shaft 1 being held in place and fixed relative to the housing 10. More specifically, the two sides of the housing 10 which connects to two of the sides of the angular shaft 1 and that the bottom of the housing 10 also comprises a recess, which in its shape is adapted to the bottom of the angular shaft 1. As previously mentioned, the first adapter 8 is mounted on the spindle unit 2 in connection with the angular shaft 1 being mounted on the spindle unit 2. Furthermore, the first adapter 8 is mainly coordinated to its outer mats with the inner mat of the upper rudder part 6, the upper rudder part 6 controlling and rotationally fixing the first adapter 8 in the upper rudder part 6. This also fixes the spindle unit 2 and the angular shaft 1 when the first adapter 8 is mounted on the telescopically extendable leg 3, see figure 1a-b. The housing 10 further comprises two resilient first tongues 11, which have a free spirit and a fixed spirit. Behind each of these resilient first tongues 11 a welding space 16 is arranged, partly so that the tongue 11 can spring in the direction of food towards the receiving space 9, and partly so that a welding plate 17 can be gripped into the welding space 16. The resilient first tongues 11 are further arranged with a wedge-shaped first welding lug 12, dangerously furthest out on the free spirit of the tongue 11. Upon insertion of the first adapter 8 in the leg 3, the first welding lugs 12 will guide the Most adapter 8 in the upper rudder part 6, which then the Most welding lugs 12 and the resilient Most tongues 11 will be pressed in the direction of the free welding space 16. This is because the welding lugs 12 with their wedge shape extend with their tip in the insertion direction in a level of the outer mat of the housing 10 and out of the same, wherein the cross-sectional mat at the second end of the respective welding lug 12, its edge 29, is larger than 9 the inner mat of the upper rudder part 6. When then the first adapter 8 arrives at its final position 14 (see Fig. 1b) in the upper rudder part 6, the first resilient tongues 11 snap back to their unloaded position, in that the upper rudder part 6 in the corresponding position has a first welding instruction 15, for the respective welding lug 12. In this layer it is then possible to insert the welding washer 17 into the respective welding space 16, for securing the first adapter 8 in the final layer 14.
    Furthermore, the first adapter 8 comprises a cantilever 22 at its upper edge 21. This is arranged to stop the continued insertion movement of the first adapter 8 into the upper rudder part 6, by stopping against the upper edge 23 of the upper rudder part 6. The housing 10 is further provided with a plurality of recesses 34 for communication with other details such as cranks, crankshafts and the like which are to drive the telescopic movement via the angular shaft 1. The 1-161 jet 10 is further provided with a groove 35 in which a screw plate 18 is inserted. The screw plate 18 in turn comprises a threaded hall 19, and the screw plate 18 is used to further anchor the first adapter 8 in the leg 3, and to obtain sufficient stability in the ready-assembled end product - the high and submersible desk. In older solutions, the angular shaft is screwed into the leg during the mounting of the spindle unit in the leg, and then during the final assembly, which often happens with the end user, where a side bracket is screwed to the leg and connects the table top and base. Because the first adapter 8 is only now snapped on during the factory assembly, this further stabilization takes place during the final assembly by screwing the side bracket (not shown) to the leg 3 to connect the table top to the base, and at the same time the final stabilization is obtained by screwing the side bracket Ors to the screwdriver 18.
    Fig. 3a shows the first adapter 8 in sieve mounted layer on the top edge 4 of the spindle unit 2.
    In this layer, the angular shaft 1 is arranged in the receiving space 9 of the first adapter 8, the housing 10 at least partially enclosing the angular shaft 1. As previously mentioned, two of the sides of the housing 10 connect to the corresponding sides of the angular shaft 1, the angular shaft 1 being fixed in the first the underside also connects the aisle rod 32 of the spindle unit 2 (not shown) to the angular shaft 1 and is loaded therein. Furthermore, the two welding trays 17 mounted in "ready-to-wear" can be seen, ready to be washed into the respective welding space 16, as previously described.
    Fig. 3b shows the upper spirit of the upper tube part 6, with the first adapter 8 mounted in its end layer 14 and the welding washers 17 in order to be washed into the welding spaces 16. In the final layer 14 the cantilever 22 of the upper adapter 8 rests on the upper tube part. 6 Upper edge 23 and further, the first welding lugs 12 have snapped into the first welding instructions 15 and thus load the first adapter 8 in the upper rudder part 6. The spindle unit 2 and the angular shaft 1 are now fixedly arranged to the upper rudder part 6 and thus to the telescopic leg 3 upper spirit. When the welding washers 17 are then inserted into the welding spaces 16, the complete spindle unit 2 is secured in the leg 3. The figure also shows the screw plate 18 infant in the groove 35.
    Figs. 4a and 4b show a view of the second adapter 24 and its fixedly mounted bearing at the spindle unit 2. The second adapter 24 comprises two resilient second tongues 26, which in turn have a wedge-shaped second welding lug 27, at their lower end. The welding lugs 27 are pointed in the spirit which is in the insertion direction, seen from the mounting of the complete spindle unit 2 in the leg 3, and in the opposite spirit the wedge shape ends with a sharp edge 29. The second adapter 24 also has a cantilever 36 which collars outwards itself. adapter body.
    The reason for this is that after the second adapter 24 Rifts into the spindle housing 33, the spindle housing 33 is sprained slightly in the area below the collar 36, the second adapter 24 being welded to the lower arid 25 of the spindle unit 2 (the sprain is not shown in the figures).
    Fig. 4c shows a section through the lower part of the lower tube part 7 where the second adapter 24 snaps into the second welding instruction 28. In the figure the second adapter 24 is seen fixedly arranged in the spindle housing 33 of the spindle unit 2 by the adapter body continuing into the spindle housing 33 , after which it is secured there by the spindle housing 33 being sprained / clamped slightly just below the cantilever 36. Furthermore, the deadly resilient second tongues 26 are also visible, which respectively comprise the second welding lug 27. During the mounting of the spindle unit 2 inside the leg 3, the complete the spindle unit 2, and thus the second adapter 24, the second welding guide 28. The second welding guide 28 consists of a plate which has been welded inside the lower end of the lower rudder part 7 and the plate comprises a square hall, centrally located on the plate. When the second adapter 24 arrives at the welding guide 28, it is guided into the tail and by the second welding lugs 27 being wedge-shaped, the resilient second tongues 26 4161 are pressed towards the center axis, after which the two second lugs 27 have just passed the tail in the second welding guide 28. , the tongues 26 spring back to their resting position and thus the second adapter 24 is fixedly arranged in the second welding instruction 28. A movement opposite the mounting direction is prevented by the other welding lugs 27 being terminated with the sharp welding edge 29. It also follows that the complete spindle unit 2 is fixedly attached to the lower rudder part 7. 11 PARTS LIST 1 = angular shaft 2 = spindle unit 3 = legs 4 = topping 6 = upper rudder part 7 = lower rudder part 8 = first adapter 9 = receiving space 10 = WO 11 = first tongue 12 = first welding lug 13 = cradle 14 = end layer 15 = first welding instructions 16 = welding space 17 = welding tray 18 = screw plate 19 = slippery A = pre-assembly torque B = mounting torque C = securing torque 21 = Upper k ant (adapter) 22 = cantilever 23 = upper edge (upper rudder part) 24 = second adapter 25 = lower spirit (spindle unit) 26 = other tongues 27 = second welding lug 28 = second welding instruction 29 = welding edge 32 = gangway 33 = spindle housing 34 = recess 35 = save 36 = cantilever 37 = lower end (lower rudder)
