Description

The invention relates to a combined securing element for use with a fixed component and a movable component.Combined securing elements are very generally known from the publications DE 10 2017 124 172 A1 and DE 10 2018 121 740 A1 and DE 199 18 911 A1.Cooking devices are known which have a cooking chamber which is formed immovably, i.e. fixed, with the cooking device and in which the items to be cooked can be arranged in or on a cookware item and can be cooked when the cooking chamber of the cooking device is closed. Such a cooking appliance can be, for example, an oven, a steam cooker, a combination appliance of an oven with steam cooker and the like. Cooking appliances of this type with a fixed cooking chamber usually have an overall height of approximately 45 cm at least in Germany along the vertical axis, wherein ovens are also customary having an overall height of approximately 60 cm.Common to cooking appliances of this type having a fixed cooking chamber is that they have an outer housing as an outer housing, which substantially encloses the cooking appliance outwards and protects the individual components and elements thereof and makes them handleable together. An interior space is formed within the cooking appliance, which represents the cooking chamber and is substantially surrounded by an inner housing as an inner housing, also referred to as a cooking chamber muffle or muffle. Between the inner housing and the outer housing, a housing space is formed as an intermediate space, in which functional elements of the cooking appliance, such as a controller or a control unit, an electrical energy supply and other components, which serve for the intended use of the cooking appliance, can be arranged. Viewed from the front in depth, i.e. viewed from the point of view of a user, the outer housing or a panel in the form of a furniture material or in the form of an operating panel and the like together with the inner housing closes off the housing space, so that the housing space is not accessible to the user.The interior of the cooking appliance has a through opening in the depth toward the front as an access opening, through which the interior of the cooking appliance is accessible to the user in order to insert cookware into the interior of the cooking appliance as its cooking chamber and to arrange them there, and in order to remove cookware from the interior of the cooking appliance and to remove them from there after the cookware has been treated. The access opening can be opened by the user by means of a closure element, for example in the form of a laterally pivotable door, a downwardly pivotable flap and the like, in order to be able to access the interior of the cooking appliance, as described above, or in order to close the interior of the cooking appliance and to carry out the cooking process or the cooking process. Such a closure element can be designed closed or have a viewing window in order to allow the user to see into the closed interior of the cooking appliance.Cooking appliances of this kind with a fixed cooking chamber are usually designed as built-in appliances or as built-in kitchen appliances in order to be arranged in a fixed manner with their outer housing in kitchen furniture such as, for example, in built-in cabinets of a kitchen in a space-saving manner and to be closed with their closure element, optionally additionally with their panel, see above, in a planar manner towards the front of the user flush with the surfaces of the remaining cooking appliances, drawers, doors and the like of the kitchen furniture, which can improve the visual impression for the user. However, such cooking devices can also be designed as individual separate devices, which can be set up and operated in particular on a working surface of a kitchen line. This can simplify flexibility of use and purchase and disposal.In cooking appliances of this type, the closure element, such as a door arranged such that it can be pivoted laterally or a flap which can be pivoted upwards from below, is operated manually by a person as a user, i.e. is gripped by the fingers of a hand on a handle, bracket or the like, and is then moved or pivoted back and forth between the fully open state in order to be able to access the cooking chamber as easily as possible and the fully closed state in order to carry out the cooking process. This can also be effected by means of a translatory movement back and forth along the longitudinal axis in that the closure element can be extended and inserted. Mixed rotational-translatory pivot movements are also possible by means of suitable kinematics. In any case, intermediate positions are also possible in order to open the cooking chamber only one gap, for example for ventilating or cooling after a cooking process.In order to relieve the user from performing these movements between the fully open state and the fully closed state, it is also known to use a drive, in particular an electric drive, for this purpose. The pivoting movements described above are here converted by means of a motor which can be driven in rotation, in particular electrically, and which can transmit its rotational movement by means of a crank into a translatory movement along the longitudinal axis, which can then, comparable to the movement of the hand of the user, pivot the closure element back and forth or up and up about its rotational axis.It is generally known, in technical devices, in particular with movable elements, to pre-assemble those assemblies which execute or implement the movement during operation and to mount them as pre-assembled assemblies in the technical device, so that the execution or transmission of the movement can take place there. In the pre-assembled state, the transport can also take place, in particular from a supplier to the manufacturer of the technical device. This also applies to the cooking appliances described above.It is problematic here that, during the transport of pre-assembled assemblies, undesired relative movements can occur between components which are movably connected to one another.In order to prevent such relative movements within pre-assembled assemblies, so-called transport securing means are frequently used. However, these must be disposed of after transport, which represents additional expense and in particular leads to additional waste, which conflicts with the general goal of sustainability.It is also a problem that during the assembly of movable components, for example a bolt which runs in a slotted link in a similar manner to a ballpoint pen, assembly errors can frequently occur if the relevant components are not positioned sufficiently accurately with respect to one another. This presents a load for the person who carries out the assembly as well as a problem in the quality assurance of the assembled assembly.In order to ensure the positioning accuracy, therefore, so-called assembly aids such as splints are frequently used, which however have to be removed and disposed of after assembly, which leads to additional waste, which conflicts with the general aim of sustainability.It is also problematic that securing the connecting element is frequently useful when connecting two assemblies. If a connecting element is not sufficiently secured, problems can arise in the function, so that it can lead to the use of a service technician, which can in turn cause outlay and costs. Furthermore, connecting elements such as bolts are frequently secured by securing rings, for example, the assembly of which can be very complicated and time-consuming.The invention addresses the problem of improving, in particular simplifying, the possibilities for pre-assembly of a module. In particular, the time outlay and or the material outlay are to be reduced. This is intended to be effected in particular for assemblies of domestic appliances. In any case, this should be possible in a manner that saves as much space, saves weight and or is cost-effective as possible. At least, an alternative to the known possibilities of this type is to be created.According to the invention, this problem is solved by a household appliance with a combined securing element. Advantageous embodiments and further developments of the invention are evident from the dependent claims which follow.Thus, the invention relates to a household appliance with a combined securing element for use with a fixed component and a movable component, wherein "fixed" and "movable" are to be understood relative to each other. The stationary component can also be regarded as the drive side and the component which is relatively movable relative thereto as the output side. The two components form an assembly of the domestic appliance.The combined securing element is configured to immovably secure the movable component with respect to the fixed component in a first use and to secure a rotational component in a second use, which rotatably connects the movable component to the fixed component.Between the two uses, the combined securing element is removed and reused as a process step in the context of an assembly process, which can be carried out manually by a person or automatically.The combined securing element according to the invention is used on the one hand as a transport securing means and as an assembly aid until the assembly, to which the movable component and the fixed component belong, are completely assembled. On the other hand, the combined securing element according to the invention is removed there and then used for securing a rotational connection which uses the assembly or its movable component with a further component of the device.Thus, a double use of one and the same combined securing element according to the invention takes place, so that obtaining and eliminating a known transport securing means and obtaining and subsequent disposal of an additional assembly aid as well as obtaining and using an additional securing element, as previously known, is avoided.According to the invention, the combined securing element according to the invention is designed to engage in overlapping recesses of the fixed component and of the movable component during the first use. In other words, recesses of the two components to be secured are brought into alignment and then the combined securing element according to the invention is guided through the aligned recesses in order to achieve a positive-locking hold at least perpendicularly to the joining direction.In this positioning, the combined securing element according to the invention can be secured along the joining direction by further measures, for example by a latching connection or the like. Alternatively or additionally, a force-fit hold in the congruent recesses can also take place, as will be explained in more detail below.In this way, more than two components can also be secured and connected to one another.According to a further aspect of the invention, the combined securing element according to the invention is to be held in a force-fit manner in the recesses of the fixed component and of the movable component during the first use. As a result, the combined securing element according to the invention can be held in the positioning along the joining direction, as already mentioned above, so that securing measures for this purpose can additionally be omitted, which can keep the outlay low. The positioning or securing perpendicular to the joining direction can also be improved as a result.According to a further aspect of the invention, the combined securing element according to the invention is designed to exert the frictional connection in a spring-elastic manner. This can bring about a particularly effective hold, in particular perpendicular to the joining direction, on account of the spring force. The exertion of the corresponding spring force can be achieved in a simple manner by an elastically deformable material of the combined securing element according to the invention. The combined securing element according to the invention can also be designed structurally in such a way, for example by means of elongate flanks which, perpendicularly to their elongate direction of extent, are nevertheless sufficiently resiliently flexible even in the case of comparatively rigid and inelastic material in order to achieve the effect described above.According to a further aspect of the invention, the combined securing element according to the invention is designed to engage around the rotational component, preferably a bolt, on both sides at its ends during the second use. This can be achieved in particular by a spring-elastic flexibility of the corresponding region of the combined securing element according to the invention, in particular its flanks. In any case, this can ensure the rotational component on both sides in the fully assembled state of the assembly in the corresponding device.According to a further aspect of the invention, the combined securing element according to the invention is designed to engage behind the fixed component and the movable component perpendicular to the axis of rotation of the rotational component during the second use. This allows the combined securing element according to the invention to be held or secured to the components, as a result of which additional measures for this can be omitted.According to a further aspect of the invention, the combined securing element according to the invention has a securing side which is designed, in a first use, to immovably secure the movable component with respect to the fixed component and, in a second use, to secure a rotational component which rotatably connects the movable component to the fixed component. This allows a specific implementation of the functions already described above.According to a further aspect of the invention, the securing side has a pair of flanks running parallel to one another, which flanks are designed, in a first use, to immovably secure the movable component with respect to the fixed component by engaging in overlapping recesses of the fixed component and of the movable component, and, in a second use, to engage around the rotational component on both sides at its end. This allows a specific implementation of the functions already described above.According to a further aspect of the invention, the flanks each have, facing one another, at least one hook which is designed, in a second use, to engage around the rotational component on both sides at the ends thereof. This allows a specific implementation of the functions already described above.According to a further aspect of the invention, the flanks are connected to one another in a spring-elastic manner by at least one central web, preferably by a pair of mutually spaced central webs. This allows a specific implementation of the functions already described above.According to a further aspect of the invention, the flanks extend beyond the central web and form there an operating side which is designed to be compressed by a person with the fingers. As a result, a leverage effect can be exerted on the flanks of the opposite securing side and the distance of the flanks from one another can be increased there in order to mount or release the combined securing element according to the invention. This allows a specific implementation of the functions already described above.According to a further aspect of the invention, the flanks on the operating side are approximately of the same length as on the securing side. This can promote a compact design, with sufficiently long flanks at the same time to bring about the securing and the operation as described above.According to a further aspect of the invention, the flanks each have at least one hook facing one another, which are designed to engage around the rotational component on both sides at its end in a second use. This allows a specific implementation of the functions already described above.According to a further aspect of the invention, the combined securing element according to the invention is formed integrally from a securing element body, preferably from plastic. This can simplify the production and keep the production costs low.In other words, a combined securing element ( 3 in 1 clip) according to the invention, which is initially used during the pre-assembly of an assembly with movable individual parts, can also serve as an assembly aid in that it fixes the components in such a way that movements are no longer permitted and the components can be assembled in a defined position.After the pre-assembled assembly has been completed, it can be supplied to a manufacturer of a device, such as in particular a household appliance, where it is then to be installed in the device or in the appliance. Since the combined securing element according to the invention, which was previously used as an assembly aid, does not allow any movement of the movable components even during transport, no problems (displacements, twisting of the components with respect to one another) occur.When mounting the pre-assembled module in the appliance (e.g. oven), a defined mounting position of the module must be ensured. Since the 3in1 clip holds the movable components in exactly this position, simple assembly into the apparatus can be ensured.Once assembly is complete and the assembly is connected to adjacent components or assemblies, the 3in1 clip is removed from the assembly and placed in the same handle on a connecting element, such as a bolt, which is secured against failure, which is thereby secured.The combined securing element of the 3in1clip according to the invention thus remains in the device or in the device, but already performs important functions during pre-assembly, transport and assembly, which secure quality on the one hand and save money and labor time on the other hand.An exemplary embodiment of the invention is illustrated purely schematically in the drawings and is described in more detail below. It shows FIG. 1 shows a perspective illustration of a combined securing element according to the invention obliquely from above; FIG. 2 shows a longitudinal section through the combined securing element according to the invention during its first use; FIG. 3 shows a longitudinal section through the combined securing element according to the invention during its second use; FIG. 4 shows a perspective illustration of a domestic appliance in the form of a cooking appliance with an open access opening obliquely from the front above; FIG. 5 shows a lateral view with a partial longitudinal section of a or through a connection kinematics with an electric motor and coupling disc of the cooking appliance of FIG. 4 with the combined securing element according to the invention during its first use; and FIG. 6 shows a lateral view with a partial longitudinal section of a or through a connection kinematics with an electric motor and coupling disc of the cooking appliance of FIG. 4 with the combined securing element according to the invention during its second use.The above-mentioned procedure is described. Figures are viewed in Cartesian coordinates. A longitudinal axis X extends, which can also be referred to as depth X or length X. A transverse axis Y extends perpendicular to the longitudinal axis X, which can also be referred to as width Y. Extending perpendicular to both the longitudinal axis X and the transverse axis Y is a vertical axis Z, which can also be referred to as height Z and corresponds to the direction of gravity. The longitudinal axis X and the transverse axis Y together form the horizontal X, Y, which can also be referred to as the horizontal plane X, Y.FIG. 1 shows a perspective illustration of a combined securing element 2 according to the invention obliquely from above. The combined securing element 2 can also be referred to as a 3in1 clip.The combined securing element 2 is produced in one piece, i.e. integrally, as an injection-molded part as a securing element body 20 which is H-shaped. The two elongated parallel sections may be referred to as flanks 21 which are perpendicularly connected somewhat centrally along their elongated extension by a pair of mutually spaced central webs 22.A section distal to the central webs 22 serves for securing or holding components 3, 4, 5 that are movable relative to one another, as will be explained in more detail below with reference to FIGS. 2 and 3, and then, however, are referred to as securing side 24 of the combined securing element 2. There, the ends of the flanks 21 are bent over so as to face each other, whereby hooks 23 are formed.Opposite the securing side 24, the flanks 21 extend in a straight line beyond the central webs 22, as a result of which an operating side 25 is formed. The flanks 21 extend approximately exactly as far on the operating side 25 as on the securing side 24. Accordingly, the flanks 21 form a pair of levers which can be compressed towards one another on the operating side 25 by a person as user or operator in order to move the flanks 21 of the securing side 24 away from one another and thus open or enlarge the intermediate space between the flanks 21 in order to engage around and hold a plurality of bodies when the force is taken from the flanks 21 of the operating side 25, as will be explained in more detail below with reference to FIG. 3.Conversely, the two flanks 21 of the operating side 25 can also be pushed apart by the person in order to move the flanks 21 on the securing side 24 towards one another and thus taper, as a result of which the flanks 21 of the securing side 24 can be introduced into a cutout and then relieved there again by the force of the person in order to exert spring forces perpendicularly outwards. The flanks 21 of the securing side 24 can also be inserted into a recess in an unloaded manner, i.e. merely guided by the person but neither pressed together nor apart, as will be explained in more detail below with reference to FIG. 2, and by the contact with the edges or edges of the recess are pressed towards one another or away from one another perpendicularly to the joining direction and thereby exert a spring force perpendicularly to the joining direction. In any case, these spring forces can bring about or improve a retention of the combined securing element 2 in the recess.The use and use of a combined securing element 2 according to the invention will now be explained in general. FIG. 2 shows a longitudinal section through the combined securing element 2 according to the invention during its first use. In this case, a fixed component 3 and a component 4 which is movable relative to the fixed component 3 during use are connected and held immovable in a force-fit and form-fit manner by means of the combined securing element 2 according to the invention for the purpose of transport and assembly, in that the flanks 21 of the securing side 24 are pushed through mutually overlapping recesses of both components 3, 4 and are held there in a force-fit manner perpendicular to the joining direction. Furthermore, the hooks 23 of the flanks 21 of the securing side 24 engage behind the fixed component 3, which can later be canceled again by pressing together the flanks 21 of the operating side 25.FIG. 3 shows a longitudinal section through the combined securing element 2 according to the invention during its second use. To implement the second use, the first use is to be ended first, as described with reference to FIG. 2, by removing the combined securing element 2 according to the invention there. Then, the combined securing element 2 according to the invention can alternatively be used in that a further or the same fixed component 3 and or a further or the same relatively movable component 4 are rotatably connected by means of a rotational component 5, for example in the form of a bolt, during use and are held or secured by means of the combined securing element 2 according to the invention. In this case too, the hooks 23 of the flanks 21 of the securing side 24 of the combined securing element 2 can be used to engage behind.A specific exemplary application and use of a combined securing element 2 according to the invention in a specific device 1 can now be effected as follows. FIG. 4 shows a perspective illustration of a domestic appliance 1 in the form of a cooking appliance 1 with an open access opening 13 obliquely from the front above. The household appliance 1 or cooking appliance 1 is considered using the example of an oven 1. The oven 1 has an outer housing 10, which can also be referred to as an outer housing 10 and substantially closes or encloses the oven 1 outwards. The outer housing 10 closes off along the longitudinal axis X toward the front, i.e. toward the user, in the upper region with a screen 10 a. Inside the outer housing 10 an inner housing 11 is arranged, which can also be referred to as inner housing 11. The inner housing 11 closes off from both sides with the outer housing 10 along the longitudinal axis X toward the rear, along the vertical axis Z toward the bottom and upward, and along the transverse axis Y, so that an intermediate space is formed between the outer housing 10 and the inner housing 11, which can also be referred to as housing space. This intermediate space represents the interior of the oven 1.The inner housing 11 furthermore substantially encloses an inner space 12 in which a cooking process can be carried out. For this purpose, corresponding elements for heating the interior space 12 (not shown) are arranged in the intermediate space or in the cooking chamber 12. Accordingly, the interior space 12 can also be referred to as a cooking chamber 12.The cooking chamber 12 is accessible to the user from the front along the longitudinal axis X through an access opening 13 which is located below the panel 10 a. The access opening 13 can be closed and opened by means of a closure element 14 in the form of a flap 13. For this purpose, the flap 14 is connected to the outer housing 10 of the oven 1 such that it can be pivoted upwards about the transverse axis Y by means of at least one hinge (not shown), so that the flap 14 can be pivoted upwards by the user in order to close the access opening 13 and can be pivoted downwards in order to release the access opening 13 and access the cooking chamber 12.The cooking chamber 12 has a side wall 12 aon each side along the transverse axis Y, on each side of which a removable receiving grid 15 is arranged. To each receiving grid 15 at the same height along the vertical axis Z a telescopic rail 16 is removably attached, which together form a pair of telescopic rails 16. The telescopic rails 16 are each formed in three parts along the longitudinal axis X (not shown), so that a respective front rail element is connected to a rear rail element of the telescopic rail 16 by means of a central rail element, wherein the rear rail element is held fixedly and removably on the respective receiving grid 15.A cookware item such as a baking tray (not shown) can be placed by the user onto the pair of telescopic rails 16 or the front rail elements thereof in order to be pushed into the cooking chamber 12 along the longitudinal axis X and pulled out of the cooking chamber 12. This can make it easier for the user to insert the baking tray into the cooking chamber 12 and remove it from the cooking chamber 12.FIG. 5 shows a lateral view with a partial longitudinal section of a or through a connection kinematic system 17 with an electric motor 18 and coupling disc 19 of the cooking appliance 1 of FIG. 4 with the combined securing element 2 according to the invention during its first use.The connection kinematics 17 with the electric motor 18 and the coupling disc 19 is arranged laterally in the intermediate space of the oven 1 and can be used by the user to operate the flap 14 as a closure element 14 by motor, in order not to have to do this itself. The motorized movement, in particular for opening the closed flap 14 and then again for closing the opened flap 14, cf. FIG. 4, can be effected by the user, in particular by actuating a corresponding operating element (not illustrated), which can be arranged on the outside on the flap 14 (not illustrated) and or on the panel 10 a(not illustrated).For guiding the connection kinematics 17, the outer housing 10 has on the inside a guide element 10 b, which points upward along the vertical direction Z and which has a through-opening (not shown) along the longitudinal axis X. Facing the user along the longitudinal axis X, a closure element connection 14 a, also referred to as tongue 14 a, is arranged pivotably on the front edge of the outer housing 10. The closure element 14 or the flap 14 (not illustrated, cf. FIG. 4 ) is fixedly mounted on the closure element connection 14 aand is thus pivotable.In the rear region along the longitudinal axis X above the outer housing 10 or its underside (not designated), the already mentioned electric motor 18 is fixedly arranged by means of a motor holder 18 b. The motor holder 18b is a disc fixedly disposed on the lower surface of the outer casing 10 in the space and has a through hole (not designated) through which a motor shaft 18a is projected. The electric motor 18 is fixedly disposed on the one side of the disc-like motor bracket 18 b, so that the rotor (not illustrated) of the electric motor 18 can drive the motor shaft 18 aprotruding from the electric motor 18 through the through hole of the disc-like motor bracket 18 bto the opposite side thereof. There, the already mentioned clutch disk 19 is arranged fixedly on the motor shaft 18 a, so that the clutch disk 19 can be driven in rotation by the electric motor 18.The side of the clutch disk 19 facing away from the disk-like motor holder 18 bhas a clutch-side guide contour 19 a. A coupling bolt 17 aengages with a first end in the coupling-side guide contour 19 a, so that there is a positive connection between the first end of the coupling bolt 17 aand the coupling disk 19, which can transmit the force from the electric motor 18 to the coupling bolt 17 a.The coupling pin 17 ais rotatably mounted by means of a pin 17 ein a corresponding through-opening (not designated) of one end of a crank 17 bwhich is rotatably connected at the opposite end to a guide rod 17 cthat is translationally movable along the longitudinal axis X and is guided by the through-opening of the already mentioned guide element 10 bof the outer housing 10. The opposite end of the guide rod 17 cis connected to the closure element connection 14 aby means of a connecting element 17 d, in order to pivot said closure element connection back and forth as already mentioned above.If the electric motor 18 is now operated and as a result, as previously known, its rotational movement is transmitted to the closure element connection 14 a, the flap 14 can be moved back and forth, as already mentioned above, by motor between a position closing the access opening 13 and a position releasing the access opening 13. In this case, the rotational movement of the electric motor 18 can be converted by means of the clutch plate 19, the clutch bolt 17 aand the crank 17 binto a translatory movement which can pivot the flap 14 upwards and upwards.In order to be able to pre-assemble an assembly consisting of the motor 18 together with the motor holder 18 b, the clutch plate 19 and the crank 17 band to be able to hold and transport them securely in this state, the securing element 2 combined according to the invention can be applied to these components as described with reference to FIG. 2. For this purpose, the flanks 21 of the securing side 24 are inserted through overlapping recesses of the motor holder 18 a, the clutch plate 19 and the crank 17 band held there as described above. This can ensure the positioning during transport and during subsequent assembly of the assembly in the oven 1.FIG. 6 shows a lateral view with a partial longitudinal section of a or through a connection kinematic system 17 with an electric motor 18 and coupling disc 19 of the cooking appliance 1 of FIG. 4 with the combined securing element 2 according to the invention during its second use. For this purpose, the combined securing element 2 according to the invention is removed from the first use and then, as a second use, is pushed over the bolt 17 e, which connects the crank 17 band the guide rod 17 cin a rotationally movable manner during use, cf. FIG. 3. The combined securing element 2 according to the invention can also continue to be used during use of the device 1 after the pre-assembly, transport and assembly of the assembly in the device 1 has been completed.In other words, the above-mentioned method is described. The assembly unit may also incorporate components which, as described above, are movable relative to one another. However, it is important for the function that an exact installation position is maintained.FIG. 5 shows an assembly which enables the automated opening and closing of a domestic appliance door in the form of a flap 14. With the aid of the illustrated connection kinematics 17, not only is the motor-driven opening and closing possible, but furthermore the flap 14 can be manually opened and closed.In order to ensure this handrail, it is necessary that the crank 17 bor the coupling rod 17 bcan also move if the clutch plate 19 or the rotary clutch is not driven by the motor 18 or by the motor shaft 18 a.If it is now proposed that during assembly, first the hinge with its individual parts 14 a, 17 d, 10 b, 17 cis inserted and then the drive unit 17 a, 17 b, 18 including the coupling disk 19 is installed as a pre-assembled module in the device 1, as here in the oven 1, a connection point is created between the guide rod 17 cor the spring holder 17 cand the coupling rod 17 b.First, the preassembly of the drive unit 17 a, 17 b, 18 including the clutch disk 19 is considered:At the beginning of the preassembly, the motor 18 is connected to the motor holder 18 band the clutch disk 19 is pushed onto the motor shaft 18 a. Then, the difficult part of the assembly starts. The clutch plate 19 must always be mounted in the same position as seen in FIG. 5. The coupling bolt 17 ais inserted into a defined position in the coupling disk 19. Subsequently, the coupling rod 17 bis pushed onto the coupling bolt 17 a.In order to ensure that the coupling disk 19 is at the correct angle and the coupling bolt 17 ais at the correct position in the coupling disk 19, the combined securing element 2 according to the invention, also referred to as 3in1clip 2, is now used. The combined securing element 2 is inserted there perpendicularly to the X-Z plane of FIG. 5 through the coupling rod 17 b, the coupling disk 19 and the motor holder 18 bor corresponding recesses (not shown) and thus prevents the coupling bolt 17 afrom slipping in the coupling disk 19 and also fixes the coupling rod 17 b, so that the latter cannot execute any pivoting movements.The transport of the drive unit 17 a, 17 b, 18 including the clutch disk 19 from Vomonture or from the supplier to the device or appliance manufacturer is now considered:During transport, slipping of the coupling bolt 17a in the coupling disc 19 is thus prevented. In addition, the coupling rod 17 bremain fixed to the motor holder 18 b,so that the latter cannot execute any pivoting movements. Care is taken to maintain the defined installation position.The mounting of the pre-assembled assembly of the drive unit 17 a, 17 b, 18 including the clutch plate 19 into the device 1 or into the appliance 1 (e.g. oven 1) is now considered:During assembly, the position of the clutch plate 19 is secured. The drive unit 17 a, 17 b, 18 including the clutch plate 19 is mounted in the device 1 by means of some fastening screws (not shown).A connection of the spring holder 17 cand coupling rod 17 binterface must then be effected. For this purpose, the aforementioned pin 17 eis used. The securing of the bolt 17 ein the Y direction of FIG. 6 is then realized with the aid of the 3in1clip 2. For this purpose, the 3in1 clip 2 is removed from the drive unit 17 a, 17 b, 18 including the coupling disk 19 and pressed onto the interface connection of the spring holder 17 cand the coupling rod 17 b. The assembly according to FIGS. 5 and 6 is now complete and the 3in1clip 2 remains in the device 1.According to the invention, a simple and cost-effective component (cent article) in the form of the 3in1clip 2 according to the invention can be used, which can assume a plurality of functions in an assembly (function integration).
