Description

The invention relates to a holding part for a mounting plate, a door operator arrangement provided therewith and an associated assembly method.

Door operators, i.e. door closers or door drives that are designed to open and/or close a connected door, are usually covered by a cover. This serves the purpose of protecting the components of the door operator from dirt and vandalism and of concealing these components from the outside. Such a door operator is made of WO 2011/ 057 652 A1 known.

This is usually done using a cover that is only open in the direction of the door operator or mounting plate. This means that a specific cover has to be made for each door operator arrangement due to their different lengths. In the case of single-leaf door systems, the cover may not extend across the entire width of the door but only over the length of the door operator. If the door operator is to be equipped with additional components such as radar detectors, smoke detectors or the like, these should also be covered. On the one hand, this can be done using a separately arranged, second cover panel. This is not very desirable visually. On the other hand, it can be done using a new, extended cover. However, this means that the previous cover can no longer be used, which leads to higher costs and waste.

The object of the invention is to counteract these disadvantages, accompanied by a very simple assembly.

This object is solved by the subject matter of claims 1, 13 and 15. Advantageous developments of the invention are specified in the subclaims.

According to the invention, a holding part is provided which has a fastening section. By means of this fastening section, the holding part is designed to be fixedly attached to a mounting plate of a door operator in a force-fitting and/or form-fitting manner. This means that the holding part is fixed in the mounting position solely due to the force-fitting and/or form-fitting connection with the mounting plate. No additional fastening means are therefore required. Within the scope of the invention, the door operator is designed to open and/or close a connected door, i.e. it is a door closer or a door drive. The fastening section comprises, for example, clamping means which come into active engagement with the mounting plate in a force-fitting and/or form-fitting manner when the holding part is attached to the mounting plate. This makes it possible to simply place the holding part on the mounting plate without additional aids and to attach it to it in a fixed position, i.e. to fasten it. This makes assembly enormously easier. The holding part also has guide sections which are designed to guide the legs of the at least one cover along the holding part when it is placed on the holding part and to hold them in (assembly) position if necessary. This makes it possible in particular to clamp the legs of the cover to a certain extent. If the legs run towards each other in the direction of their free ends, they can be pressed apart by the guide sections so that they reach their final, preferably parallel alignment. This pressing apart also helps to hold the cover on the holding part. This makes it possible to attach covers which are significantly longer than the respective door operator without additional aids. Such covers are used in particular when additional components such as radar detectors, smoke detectors and the like are mounted on the mounting plate in addition to the door operator and are to be covered by one and the same cover. The use of a single cover over the entire length of the door operator arrangement or its mounting plate allows the use of a single, continuous and visually desirable cover.

The holding part preferably also has first locking sections that are designed to engage behind legs of the at least one cover hood that is essentially U-shaped in cross section in the direction of a wall section connecting the legs. The cover hood is thus held by the holding part and does not have to be attached to the mounting plate in any way, which leads to very simple assembly with a secure hold. The U-shape has the advantage that the cover hood does not have to be closed off at its end faces. This makes it possible to produce the cover hood as a preferably endless extruded profile, for example by means of extrusion, and to simply cut it to length depending on the application, which enables very simple and cost-effective production.

Additionally or alternatively, the holding part also has a holding section which is designed to hold an end cap on a side facing away from the door operator. This enables the use of the aforementioned U-shaped or groove-like cover hood. This means that the cover hood is open towards the end faces.

The holding part can also or alternatively have an insertion aid for an intermediate cover part. The intermediate cover part is designed to cover the front edges or borders of two immediately adjacent cover hoods or parts in the direction of the respective holding part when assembled. This enables a relatively small number of cover hoods of different lengths to be produced. It also enables the optical extension of the cover hood without having to throw away the cover hood that is already in use, which saves costs and helps avoid unnecessary waste.

The insertion aid preferably comprises locking sections that are designed to engage behind the intermediate cover part in the direction opposite to its insertion direction. This means that the holding part not only holds the cover(s) but also the intermediate cover part. This has the advantage that the mounting plate only has to hold the holding part and not any other part attached to it.

Additionally or alternatively, the intermediate cover part and/or the holding part can have stops that support a respective end face of at least one cover. This means that the intermediate cover part supports a cover or the like that is placed on top to visually conceal the door operator from the outside. This simplifies the positioning of the cover.

Door drives, particularly their drive motors, are often subject to heat development. In the case of active heat dissipation, this heat is usually dissipated by means of fan(s). The fan(s) either suck warm air out of the drive or blow cool air into it. To ensure that this is also possible when the cover is in place, the holding part additionally or alternatively has a first through-opening. This first through-opening is designed in such a way that, when the holding part is assembled, it runs parallel to a longitudinal extension of the mounting plate and is aligned with the cooling ventilation flow of the door operator. This makes it possible to direct the air flow from or to the door operator through the holding part, namely its first through-opening, and thus to be able to maintain the cooling of the door operator.

In the case of a double-leaf swing door, for example, i.e. with a moving leaf and a passive leaf, two door operators are usually provided. If both door operators have active cooling, in which the air from the respective door operator is pushed in the direction of the other door operator or is sucked towards it, the problem arises that the air must escape from the arrangement, i.e. from the cover arrangement, to the outside or be introduced from the outside. To make this possible, the holding part additionally has at least one second through-opening, which, when the holding part is assembled, is formed on a side of the holding part that runs essentially parallel to a longitudinal extension of the mounting plate. If the cover has, for example, slot-like ventilation openings on this at least one second through-opening, the waste heat can be dissipated to the outside or enter the inside through the at least one second through-opening and the corresponding ventilation opening(s) in the cover.

In this case, the holding part preferably further comprises a holding section which is designed to hold an air flow diversion part. The air flow diversion part is attached in such a way that, depending on the air flow direction, the air flow diverted by means of the air flow diversion part can exit or enter the holding part or enter it, namely through the corresponding second through-opening. The air flow diversion part is inserted into the aforementioned first through-opening.

The holding part can also have channel-like cable guides that, when the holding part is assembled, extend along the longitudinal extent of the mounting plate. These cable guides allow the cables to be laid in a targeted manner, for example to electrically connect two door drives of a double-leaf swing door arrangement to one another. If the aforementioned first through-opening is present, the cable guides are preferably designed in such a way that the laid cables do not reach the area of the first through-opening and thus the air flow area, which serves to ensure operational safety.

The holding part can also have a holding and/or insertion aid for at least one electronic component, preferably with a circuit board, which in turn can have actuating elements such as switches, display elements (LEDs, ...) or the like. It is provided that the electronic component or its circuit board can be attached before cladding elements in the form of covers or end caps are attached. This makes it possible to electrically wire the circuit board before fitting the associated cover.

Additionally or alternatively, the holding part further has a, in the assembled state of the holding part, in the direction of the longitudinal extension of the mounting plate The side has stop surfaces for parts of the door operator. This makes it possible to attach the holding part directly to the door operator, which means easier positioning and therefore simplified assembly.

A door operator arrangement according to the invention comprises at least one door operator and at least one mounting plate which is designed to hold the at least one door operator and to be fixedly attached to a supporting body such as a door lintel, a frame or the like. The arrangement further comprises at least one of the aforementioned cover hoods and at least one of the aforementioned holding parts.

In a further development, the arrangement preferably comprises an associated intermediate cover part for each holding part.

A method according to the invention for assembling such a door operator arrangement comprises a first step of attaching the at least one mounting plate to the support body. A second step provides for the attachment of the at least one door operator to the associated mounting plate. In a third step, the at least one holding part is placed on the associated mounting plate or fixedly attached to it. The at least one cover is then placed on the mounting plate or the associated door operator and on the associated holding part.

If provided, at least one intermediate cover part is then placed on the corresponding holding part.

1 shows parts of a door operator arrangement 1 according to a first embodiment of the invention. This embodiment is designed for a door leaf that is independently operated by a door operator. For the sake of clarity, the door operator itself is not shown.

The arrangement 1 comprises a mounting plate 10 which is attached in a known manner to a supporting body (also not shown) such as a door frame, a door lintel, a door leaf or the like.

A cover 20 is placed over the mounting plate 10 so that it is concealed from the outside. The cover 20 has at least 1 downwards, i.e. in the -z coordinate direction, but preferably also on the opposite, non-visible side, i.e. in the +z coordinate direction, a respective recess or opening 21 which serves to expose the respective end of the output shaft of the door operator in order to couple it in a known manner, for example to a drive rod.

On in 1 At the left end, a side panel 40 is arranged, for example in the form of a perforated panel, which closes off the entire cover or the cover hood 20 at the front. This means that the side panel 40 has the function of an end cap and, in the example shown, enables the arrangement of a switch part 50 with, for example, two switches 51, 52. Here, to the left of the switches 51, 52, the side panel 40 again has, for example, matrix-like through openings that form a ventilation grille 42.

The ventilation grille 42 serves the purpose of allowing air to flow into the interior between the cover 20 and the mounting plate 10 or to remove warm air from it to the outside. Warm air can arise in particular in electrical, particularly motor-operated door operators. The load on the motor when opening or closing the connected door leaf or the electrical components such as power supplies and the like for power supply and control can lead to heat being generated in the door operator. If the heat were not dissipated, the door operator could overheat and be damaged. This can of course also apply to any additional components such as light curtains, radar detectors or etc., which may also be covered by the cover 20. To prevent this, the heat must be dissipated, either by convection or by means of active fans. To ensure this, cool air must be able to enter the interior space from the outside at least at one point and to exit from the interior space at least at one other point.

If it is an arrangement 1 which has a minimum distance from the front or the side panel 40 to an adjacent wall such that the air can flow unhindered into one front of the arrangement 1 and out at the other front, a solution using the aforementioned ventilation grille 42 is recommended. 1 There is preferably also a side panel at the right, concealed end, which can be designed similarly to the side panel 42 with regard to the air flow. This creates an almost invisible air flow implementation.

2a shows the arrangement 1 of 1 in an exploded view. As can be seen, the cover 20 is not attached directly to the mounting plate 10. Rather, this is done via a holding part 100 according to an embodiment of the invention.

The holding part 100 is fixedly attached to the mounting plate 10 by means of a fastening section 110. The block arrows represent in simplified form the directions in which the respective part 20, 40, 50, 100 is placed on or inserted into the respective associated part 100 or 10.

The switch part 50 comprises, for example, a circuit board 53 on which the switches 51, 52 are arranged. Furthermore, a connection cable 54 leads from the circuit board 53, for example to a control circuit (not shown). The switch part 50 is, for example, inserted from above into 2a inserted into the holder part 100, preferably without additional fastening means. The side panel 40 is then placed on the front side of the holder part 100.

The side panel 40 has through-holes or switch openings 41 for the access of the switches 51, 52 so that they can be operated from the outside in the assembled state.

In order to allow the air to flow from the side panel 40 or its ventilation grille 42 to the door operator (not shown) or in the opposite direction, the holding part 100 has a through opening 151 (explained in more detail later, not shown here) which, in the assembled state, is aligned with the ventilation grille 42 and extends along the longitudinal extension of the mounting plate 10. The through opening 151 is in 5a more clearly visible and also designated there.

2 B shows the holding part 100 of 2a with mounting plate 10 and in the assembled state. This makes the effect of the fastening section 110 of the holding part 100 clear. In the assembled state, clamping projections 114 engage behind corresponding engagement projections 11 of the mounting plate 10, which preferably extend as continuous projections over the entire length of the mounting plate 10 and are also designed to face each other, as shown in particular in 2 B and 2c to recognize.

It can also be seen that the holding part 100 has an open recess 101 that preferably points upwards, i.e. in a direction away from the fastening section 110. The recess 101 serves to pass through additional parts of the door operator arrangement 1 (not shown). Such parts can be electrical and/or hydraulic lines or tubes, Bowden cables, operating rods, etc. In the case of a double-leaf door system, such parts can be part of a closing sequence control, for example. The recess 101 that is open on one side allows such parts to be easily inserted when the holding part 101 is mounted.

The recess 101 can of course be closed at the top so that it forms a kind of through-channel. In this case, the aforementioned parts are pushed through the holding part 100.

2c shows a front view of arrangement 1 of 2 B , i.e. in the ±x coordinate direction. As can be clearly seen, the fastening section 110 of the holding part 100 with the preferably continuous recess formed by the projections 11 encloses a cavity 12, for example. The cavity 12 can be used to lay connecting cables. This enables, for example, the laying of power supply cables and control cables from one door operator to the other in the case of double-leaf swing doors with two door operators. The cavity 12 allows the power supply for both door operators to only have to be coupled to an external power supply and, for example, a house bus on one side of the door operator arrangement 1 thus formed, which enormously simplifies the wiring and in particular the house cabling with cable ducts, etc. The power supply of the door drive arranged remotely from this side is achieved by laying "internal" power supply cables to the remotely arranged door drive through the mounting plate. In addition to power supply cables, of course Control and/or data lines, for example of a house bus, can also be laid and connected. The holding part 100 has an additional advantage in this case. It acts as a cable hold-down and as mechanical protection against damage to the cables laid underneath. This means that the holding part 100 offers mechanical protection for the cables in the area of the holding part 100 and also serves to guide the cable along the mounting plate(s) 10. When assembling, the cables are therefore preferably laid first and then the holding part 100 is placed on the associated mounting plate 10.

2d is a sectional view along a line A - A in 2 B As can be seen, the fastening section 110 of the holding part 100 is formed, for example, by means of a wall section that protrudes in the direction of the mounting plate 10 and is quasi S-shaped in cross section. This wall section comprises a preferably straight central web 111, at the ends of which an arc-shaped guide web 112 is connected.

The guide webs 112 extend from the central web 111 to the latter at a predetermined, acute or right angle and each make an elliptical, preferably circular curvature in the direction of the starting point of the other guide web 112 until the free end of the respective guide web 112 points in a direction substantially parallel to the longitudinal extension of the mounting plate 10 in the assembled state; they run towards each other, so to speak.

Preferably, the end of each guide web 112 is followed by a stop web 113 which, in the assembled state, preferably extends parallel to the longitudinal extension of the mounting plate 10.

A clamping or locking web 114 is preferably formed on each stop web 113, which is formed on a side of the respective stop web 113 facing the mounting plate 10 and extends essentially at a right angle thereto. This means that the stop web 113 and the formed clamping or locking web 114 form a wall profile with a T-shaped cross-section or, as shown here, an L-shaped cross-section. The clamping or locking webs 114 prevent the holding part 100 from falling out of the mounting plate 10.

So that the holding part 100 can be clamped or locked to the mounting plate 10, the webs 111 - 113 are formed on a wall section 115 that runs essentially parallel to the clamping or locking webs 114. This creates a space between the wall section 115 and the clamping or locking webs 114 that can be used for clamping or locking to the mounting plate 10.

The fastening section 110 preferably comprises additional fastening openings 116, here in the form of U-shaped recesses that extend along the longitudinal extension of the mounting plate 10 in the assembled state. The fastening openings 116 serve to screw the holding part 100 to the mounting plate 10 in order to improve the hold.

The mounting of the holding part 100 is carried out as follows: The holding part 100 is inserted from above, i.e. in the -y coordinate direction, into 2d , placed on the mounting plate 10, whereby the holding part 100 must be rotated around the y-coordinate axis so that the fastening section 110 fits through the gap between the mutually facing projections 11. In the simplest case, the holding part 100 is inserted rotated by 90° around the y-coordinate axis, i.e. is transverse to the position according to 2d If the holding part 100 rests with its intermediate wall 115 on the projections 11, the holding part 100 is now rotated about the said y-coordinate axis according to 2d rotated counterclockwise until the stop webs 113 rest against the corresponding projections 11. Here, the role of the curved guide webs 112 and the stop webs 113 becomes clear: The guide webs 112 enable the rotation of the holding part 100 around the y-coordinate axis in the said gap and guide the fastening section 110 along the projections 11, 11 of the mounting plate 10. The stop webs 113 as straight extensions of the guide webs 112 allow rotation in only one assembly rotation direction. This effectively prevents the holding part 100 from being installed incorrectly, which helps reduce the error rate during assembly. In addition, they limit the rotation of the holding part 100 in the correct direction of rotation, thus signaling to the installer when the holding part 100 has reached its final assembly position.

The stop webs 113 can also be omitted. In addition, the guide webs 112 can be semicircular. In this case, the stop is omitted in the assembled state, but the holding part 100 can be rotated in both directions about the y-coordinate axis.

The distance between the intermediate wall 115 and the locking or clamping projections 114 is preferably somewhat smaller than the thickness of the associated projection 11 of the mounting plate 10 in the area where they engage with one another. As a result, the holding part 100 is clamped to the projections 11 during the aforementioned rotation.

Alternatively or additionally, the locking or clamping projections 114 have locking projections at their ends remote from the stop web 113, which extend in the direction of the intermediate wall 115. In this case, the projections 11 preferably have continuous locking recesses. When the holding part 100 is screwed in as mentioned above, the locking projections come into locking engagement with the corresponding locking recesses. For this purpose, the locking or clamping projections 114 are preferably designed to be spring-loaded.

To further facilitate assembly, the recesses 116 are each open in the direction opposite to the direction in which the nearest stop web 113 points. The recesses 116 are thus open in opposite directions to one another. As a result, the fastening screws 2 can be accommodated in the recesses 116 at the same time as the holding part 100 is screwed in and only need to be tightened.

2e shows the arrangement 1 of 2 B from a different perspective, namely from the direction of the holding part 100 onto the mounting plate 10. As can be seen, the holding part 100 is fixed to the mounting plate 10 via the aforementioned fastening sections 116 using fastening screws 2. In this case, the locking or clamping effect with respect to the projections 11 of the mounting plate 10 can be dispensed with. The design of the fastening sections 116 as recesses open on one side allows the fastening screws 2 to be screwed into the mounting plate 10 in advance, the holding part 100 to be inserted into the mounting plate 10 as explained above, pushed in the mounting plate 10 in the direction of the fastening screws 2 until the recesses 116 hit the fastening screws, and finally the screws 2 to be tightened. In other words, the assembly is only slightly more complex than assembly without fastening screws 2.

3 shows parts of a door operator arrangement 1 according to a second embodiment of the invention, without mounting plate 10. This embodiment is designed for a door system in which the respective door operator is expanded to include additional components such as radar detectors, smoke detectors or the like, and/or in which it is a double-leaf door system, each of whose leaves is operated by an associated door operator. Alternatively, it is, for example, a sliding, folding or other door system.

As in 3a As can be seen, two cover hoods 20 are attached to both sides of the holding part 100. This means that the holding part 100 does not form the end of the door operator arrangement 1 but rather a connection between two cover hoods 20 arranged directly next to one another. The cover hoods 20 do not necessarily abut one another. In order to cover the gap between them or the ends of the cover hoods 20 facing one another, an intermediate cover part 30 is placed from the outside onto the holding part 100 and the ends of the cover hoods 20 facing one another as a type of cut edge cover and, as explained later, is attached to the holding part 100.

As can be seen, the cover hoods 20 and the intermediate cover part 30 end at the same height in the direction of the mounting plate 10 (not shown), so to speak, so that the cover visually forms a unit.

As further stated in 3a As shown, each cover 20 has groove-like recesses 22 on the inner sides of its free legs 23 facing each other, running along its longitudinal extent. These engage in corresponding locking projections 125 of a respective insertion aid 120 of the holding part 100 and are held thereby.

The continuous recesses 22 enable the production of extruded profile-like cover hoods 20, since these no longer have to be closed at the front. Alternatively, the recesses 22 can of course only be formed in the area of the holding part 100.

Furthermore, the cover hoods 20 can still be designed with a closed end. In this case, the 1 shown side panel 40.

This results in particularly simple assembly of the cover hoods 20; they only have to be pushed onto the holding part 100 until they lock into place with the holding part 100. However, all other fastening methods such as clamps, screwing, etc. are also possible.

In order to further simplify the placement of the cover hoods 20, the holding part 100 has the aforementioned insertion aids 120 assigned to each leg 23 of the cover hoods 20. Each insertion aid 120 has a leg guide section 121 which has a guide edge 122 facing the respective associated cover hood leg 23. This means that when the respective cover hood 20 is placed on, its legs 23 slide along the respective associated guide edge 122. This enables the production of cover hoods 20 whose legs run slightly towards each other in the direction of their free ends. When placed on the holding part 100, the legs 23 are spread apart, creating a clamping effect that improves the hold of the cover hood 20 on the holding part 100.

So that the cover 20 cannot be pushed too far onto the holding part 100, each insertion aid 120 preferably also has a support projection 123 which extends in the direction of an intermediate wall section 24 of the cover 20 which connects the legs 23. The end of the support projection 123 facing the intermediate wall section 24 forms a support surface 124 against which the intermediate section 24 rests in the assembled state. This prevents the cover 20 from being pushed on too far by mistake.

As can be seen, the intermediate cover part 30 has slots 32 on the side of at least one leg 31, namely preferably in the area of its free end. An air guide part 60 according to a first embodiment of the invention is inserted into the holding part 100 as an example. As can be seen, the air guide part 60 has two arched wall sections 61 which, even if not visible, run towards each other in the direction of the right cover hood 20 and end to the left of the slots 32 in the view. As a result, air from the outside can be redirected through the slots 32 from the wall sections 61 in the direction along the longitudinal extension of the mounting plate 10 to the components of the door operator arrangement 1 to be cooled or in the opposite direction, as indicated by the dashed block arrow. This means that the air flow does not run through the front side of the arrangement 1 but is guided out to the side.

This is advantageous, for example, in double-leaf swing doors, where two door operators face each other, so to speak, and are usually covered by a continuous cover, indicated here by two cover hoods 20 and an intermediate cover part 30. As a result, the respective front exit or entry point for the air flow is missing in the area between the door operators. Convection would be impossible. Active fans would generate a negative or positive pressure in this area. Otherwise, one door operator would receive exhaust air that has already been heated by the other door operator, which could impair the cooling of this one door operator. As a result, effective cooling of the components would be difficult or even impossible. The side ventilation openings formed by the slots 32, only one of which is visible here, offer an optimal solution for this.

3b shows the arrangement 1 of 3a from a different perspective, without the intermediate cover part 30 for illustration purposes. Here, the locking between the left cover 20 or its locking recess 22 and the associated locking projection 125 can be seen again. The cover hoods 20 are spaced apart from one another such that a through opening 152 of the holding part 100, which will be explained in more detail later, is not covered by any of the legs 23 of the cover hoods 20 and thus the aforementioned air flow is still possible. In order to ensure this distance during assembly and beyond, the holding part 100 preferably has on both opposite sides for the 3 left cover 20 has a stop web 127. Each stop web 127 extends from the side of the holding part 100 facing a respective leg 23 of the cover 20 in the direction of that same leg 23. The stop web 127 covers a side facing it, i.e. diagonally to the right and bottom in 3b facing front surface 25 of the adjacent, here left leg 23 of the here left cover hood 20. The left cover hood 20 can therefore not be moved over the 3b shown position to the right and thus possibly cover the through opening 152.

3c shows the arrangement 1 of 3a again from a different perspective, for illustration purposes this time without the holding part 100. So that the right cover 20 can now also be 3 cannot cover the through opening(s) 152 of the holding part 100 (not shown) and thus impede the aforementioned air flow, the intermediate cover part 30 preferably has a wall section 33. The wall section 33 extends similarly to the stop webs 127 in the direction of the respective associated leg 23 of the right cover hood 20. The wall section 33 covers a facing it, i.e. diagonally to the left and down in 3c facing front surface 25 of the adjacent leg 23 of the right cover hood 20.

This solution has two decisive advantages.

If, on the one hand, an intermediate cover part 30 with ventilation slots 32 is placed on the holding part 100, the stop webs 127 of the holding part 100 and the wall sections 33 of the intermediate cover part 100 ensure that only the intermediate cover part 30 with its ventilation slots 32 can cover the through opening(s) 152 of the holding part 100. The aforementioned air flow is thus maintained.

On the other hand, if no intermediate cover part 30 is fitted and contains the 3 right cover 20 has ventilation passages at the corresponding points at the through openings 152, the stop web 127 in this case forms a stop for both cover hoods 20.

4 serves mainly to illustrate the attachment of the aforementioned air guide part 60 according to the first embodiment of the invention on the holding part 100. In order to be able to guide the air flow, as described above, laterally out of the holding part 100 or into it, the holding part 100 has, as in 4a shown, preferably on both opposite sides a respective through opening 152, of which only the front one is visible.

The air guide part 60 is inserted into the aforementioned through-opening 151 of an air guide part fastening section 150 of the holding part 100 and essentially closes it. This means that the air guide part 60 at least largely prevents the air flow from passing through the through-opening 151 in the direction along its extension. The air guide part 60 preferably has locking lugs 65 on two opposite sides, which engage behind a respective locking recess 118, 154 of the holding part 100. In the assembled state, each locking recess 118, 154 points in the direction of the component(s) to be cooled. The air guide part 60, as stated above, preferably has two air guide sections 61 in the form of wall sections that are curved in the direction of the respective through-opening 152. In 4a only one air guide section 61 is visible. The wall sections open at their mutually facing ends into an air dividing section 67 connecting the wall sections, for example in the form of a rounded tip. The tip points in the same direction as the locking recesses 118, 154. As a result, the air flow coming from the components to be cooled is divided by the air dividing section 67 into the air guide sections 61, which in turn redirect the air flow in the direction of through-openings 152. In the opposite flow direction, the air guide sections 61 direct the air flows entering the holding part 100 from the side in the direction of the component(s) to be cooled.

As can also be seen from this illustration, each stop web 127 is preferably formed at an angle of approximately 90° onto a preferably springy or elastic wall section 129. In the assembled state, each wall section 129 extends essentially along the longitudinal extent of the mounting plate 10. In the example shown, the wall section 129 is cut free. This enables the wall section 129 and thus the stop web 127 to move into the interior of the holding part 100. Furthermore, the stop web 127 tapers in the direction away from the mounting plate 10 (not shown) in the direction of the wall section 129. This results in a run-on slope 128. This is for the 1 The cover 20 is designed for the case outlined when the air flow does not have to be guided out of the cover 20 at the side. In this case, the legs 23 of the cover 20 cover the respective through opening 152 of the holding part 100 facing it and thus prevent or significantly impede the air flow through the corresponding through openings 152 of the holding part 100. When the cover 20 is mounted in this way, the cover 20 is pushed over the run-on slope 128 in the direction of the mounting plate 10 onto the holding part 100. Due to the springy or elastic design of the wall section 129, the stop web 127 can escape through the associated through opening 152 of the holding part 100 into the interior of the holding part 100. This enables or facilitates the sliding of the cover 20 over the respective stop web 127.

The air guide part 60 preferably has at least one side edge 63a which, in the assembled state, lies opposite a stop web 127 facing it. Said side edge 63a preferably rests against the same stop web 127, so that the stop web 127 is prevented from moving into the interior of the holding part 100. Alternatively, the side edge 63a has such a distance from this stop web 127 that the stop web 127 cannot be pushed as far into the interior of the holding part 100 when the cover 20 is pushed on as mentioned above, as if the air guide part 60 were missing. In both cases, this leads to the fact that when the cover 20 is pushed on as described above, the leg 23 of the cover 20 facing this stop web 127 is pushed away from the holding part 100 by the run-on slope 128 of this stop web 127 to such an extent that the locking recess 22 of this leg 23 no longer aligns with the 3a shown, associated locking projection 125 of the holding part 100. During assembly, the typical locking feeling and/or noise would be missing. The respective leg 23 would also be bent away from the holding part 100 in an unusual manner. This can signal to an installer in three ways (haptically, acoustically, visually) that the cover 20 is not correctly installed.

4b shows the arrangement of 4a from a different perspective. 4c shows the arrangement of the in relation to 4a opposite side. Here, the closure of the through-opening 151 by the air guide part 60 becomes clear with regard to the air flow. As can be seen, the air guide part 60 has locking projections 66 on the side opposite the locking lugs 65, which extend transversely to the extension of the through-opening 151 in the assembled state. They lie in the direction of the locking lugs 65 on an associated intermediate wall 115 or on support projections 117 formed on it or on an intermediate wall 153 of the holding part 100. In the example shown, there are four locking projections 66.

The support projections 117 are preferably spaced apart from one another such that the facing locking lug 65 of the air guide part 60 fits in such a way that the air guide part 60 is guided over the locking lug 65 during insertion and thus tilting of the air guide part 60 is at least made more difficult.

The projections 66 formed in pairs at the top and bottom can of course be replaced by a respective locking projection which extends transversely to the extent of the through opening 151.

Preferably, the locking projections 66 are designed such that the 4c lower locking projections 66 in the direction of the intermediate wall 115 and the 4c upper locking projections 66 in the direction of the intermediate wall 153 and all preferably continuously thicken or diverge away from each other. They are thus able to engage behind complementary engagement surfaces of recesses 119, 155 and thus fix the air guide part 60 in the holding part 100.

Based on the three representations in 4 It becomes clear why the locking lugs 65 are designed to be bevelled towards each other in the direction of the components to be cooled. During assembly, the air part 60 is pushed into the retaining part 100 from the side facing the viewer. 4c pushed into the through-opening 151. The slopes of the locking lugs 65 enable or facilitate the locking lugs 65 being pressed towards one another by the intermediate walls 115, 153 and being able to pass through the through-opening 151. Once the locking lugs 65 have reached the locking recesses 118, 154, they snap back and thus engage behind these locking recesses 118, 154. In this position, the locking projections 66 of the air part 60 preferably lie at the same time on the surface of the associated locking recess 155 of the holding part 100 facing them or are only a small distance from this surface. This means that the air part 60 is assembled simply by pushing the air guide part 60 into the through-opening 151 until the locking lugs 65 snap into place, which represents a very simple and error-free assembly, particularly without additional aids.

4d and 4e show the air part 60 in greater detail. As can be seen, the air guide part 60 is designed symmetrically with respect to the x-coordinate axis. This simplifies assembly in that the fitter does not have to pay attention to which side is the top. The beveled locking lugs 65 can be seen particularly well. As also shown, the locking lugs 65 form free ends of an arm 68 that is cut out or free and is thus designed to be springy or elastic. This enables the respective arm 68 to move into the interior of the air guide part 60 and thus the above-described insertion into the holding part 100 (not shown here).

As further shown, the air guiding sections 61 preferably open at their end facing away from the air dividing section 67 into a preferably flat rear wall 63, which takes over the rest of the air diversion and also essentially closes the through opening 151 of the holding part 100. Above and below the air guiding sections 61, these are formed or connected to the rear wall 63 in the same material. Two wall sections 64 run transversely to the rear wall 63. The rear wall 63, the air guiding sections 61, the wall sections 64 form respective recesses 69, as in 4e These are used as a grip for the fingers of a fitter. This means that the fitter takes the wall sections 64, 64 of the air guide part 60 between two fingers and presses the air guide part 60 with the air dividing section 67 first into the holding part 100 until the previously described locking mechanisms of the holding part 100 and air guide part 60 engage, which represents a very simple assembly. The rear wall 63 enclosing the air guide sections 61 on the outside has the advantage that the air guide part 60 does not slide along opposite parts or surfaces of the holding part 100 when inserted and thus the risk of damage, for example in the form of broken projections on the air guide part 60 or on the holding part 100, is significantly lower.

Preferably, additional wall sections or walls 62 close the gaps between the air guide sections 61, the rear wall 63 and the wall sections 64. This means that the installer's fingers cannot get caught or jammed in the air part 60 during assembly, which makes assembly less prone to errors. In addition, the wall sections 62 stabilize the shape of the air guide part 60.

5 serves to illustrate the attachment of the aforementioned switch part 50 to the holding part 100. As in 5a As shown, the holding part 100 has a switch part fastening section 160 for this purpose.

The section 160 of the holding part 100 comprises, for example, support projections 161. The support projections 161 extend from the intermediate wall 153 in the direction away from the fastening section 110 and form a support for the switch part 50 or its circuit board 53 at their free end.

Furthermore, the section 160 has guide sections 162 which extend or protrude in a direction both transverse to the protruding direction of the support projections 161 and transverse to the extension of the through-opening 151 of the holding part 100. The guide sections 162 laterally enclose the switch board 53 and guide it in a lateral direction. Advantageously, the mutually opposite guide sections 162 of the 5a upper and/or lower pair of respective guide sections 162 to hold the switch board 53 in position. The support projections can of course be omitted, so that the switch board 53 preferably rests on the intermediate wall 153 itself.

Additionally or alternatively, the switches 51, 52 of the switch part 50 also provide support. As in 5b As can be seen, the section 160 preferably also has locking projections 163 which extend towards one another at the side of the switch part 50 in a similar way to the guide projections 162. Each switch 51, 52 has a plate-shaped part with an opening for the electrical switching element 51a, 52a of the respective switch 51, 52. The switching elements 51a, 52a are designed as rocker switches, for example. The plate-shaped parts serve as support sections 51b and 52b, respectively. This means that the switches 51, 52 come to rest on the locking projections 163 with the sections 51b, 52b in relation to the holding part 100 from the outside. Towards the switch board 53, the sections 51b, 52b are adjoined by clamping sections 51c, 52c, which are preferably designed to be spring-loaded and are formed on the side of the switches 51, 52 and protrude in the direction of the respective associated locking projection 163. They are designed in such a way that they engage around the locking projections 163 with the support sections 51b, 52b so that the switches 51, 52 are held in place, whereby the entire switch part 50 is held in position.

The assembly is now carried out as follows: First, the switch board 53 is inserted from above into 5 , i.e. in the -y coordinate direction, into the holding part 100. If the locking projections 163 are now located between the clamping sections 51a, 52a and the switch board 53, the switches 51, 52 are simply pressed in the direction of the holding part 100 along the extent of the through-opening 151 until the clamping sections 51a, 52a have overcome the locking projections 163, thus locking in place and the switch part 50 thus has the 5b shown position. This means that this assembly is also very simple and not very prone to errors.

In the example shown, the guide sections 162 are formed by means of four block-like projections. Alternatively, the guide sections 162 can also be formed by means of two side walls, for example.

6 shows the holding part 100, provided with the 3 shown intermediate cover part 30. The holding part 100 has an intermediate cover part fastening section 170. The section 170 comprises, for example, a guide section 171 on two opposite sides facing the intermediate cover part 30, which guide the intermediate cover part 30 when it is put on so that it is correctly mounted. Each guide section 171 comprises, for example, a first guide wall 172 and two second guide walls 173, which protrude in the direction of the intermediate cover part 30. As in 6e As can be seen, the pairs of first and second guide walls 172, 173 are spaced apart by a predetermined distance a from one another and thus form a respective groove-like recess 174. The respective, corresponding guide wall 33 of a guide section (not designated in more detail) of the intermediate cover part 30 is guided along these recesses 174.

As in 6a As can be seen, the intermediate cover part 30 is pushed onto two outer sides of the holding part 100, which run parallel to the extension of the through-opening 151, in the direction of the mounting plate 10 (not shown). It can also be seen that the intermediate cover part 30 and the holding part 100 are pushed forwards and backwards, i.e. parallel to the extension of the through-opening 151 or in the ±x coordinate direction in 6a enclose a gap in which a front end of a respective cover hood 20, not shown for illustration reasons, facing it is accommodated. The gap is formed between the respective leg 31 and the directly adjacent, opposite inside guide walls 172, 173 of the holding part 100. The gap preferably has a width that is slightly less than the thickness of the accommodated leg 23 of the respective cover hood 20. This makes it possible to clamp the cover hood 20 between the intermediate cover part 30 and the holding part 100 and thus hold it in position.

In order to further facilitate assembly, for example only the first guide walls 172 have guide webs 175 formed on their free, protruding ends along at least part of their longitudinal extension, which extend in the direction of associated second guide walls 173 and are at a predetermined distance b from them. Accordingly, the guide walls 33 of the intermediate cover part 30 each have guide webs 36 formed on their free, also protruding ends, which extend in the direction of the corresponding guide webs 175 in the assembled state. The guide walls 33 each have a thickness that is preferably slightly less than a distance b between the guide webs 175 and the guide surfaces 178 of the section 171 running essentially parallel thereto. This makes it possible to push the guide walls 33 between the associated guide walls 172, 173 or between guide walls 172 and guide webs 175 of the holding part 100 without great resistance.

The guide webs 36, 175 form with the integrally formed guide walls 33 and 172 respectively T- or L-shaped wall sections in cross section, as in 6c can be seen. In conjunction with the associated leg 31 of the intermediate cover part 30 or an associated side wall of the holding part 100, a respective, preferably U-shaped guide groove is created for a respective one of the guide webs 36 of the intermediate cover part 30. The guide grooves thus formed are open to one another and form a respective receptacle. The guide web 36 or 175 of the guide sections of the other part 30 or 100 engages in the receptacles thus formed. This means that the guide webs 36, 175 engage behind one another and thus keep the intermediate cover part 30 constantly engaged with the holding part 100; the parts 100, 30 cannot easily separate from one another.

In order to hold the intermediate cover part 30 in the final assembly position, a locking mechanism is preferably also provided. For this purpose, the guide walls 33 preferably have locking recesses 37 on their sides facing the holding part 100. These are exemplary, as in particular in 6b , in the area of the ends of the guide walls 33 facing the free ends of the legs 31. The holding part 100 accordingly has locking projections 176 corresponding to the locking recesses 37. These are, as in 6a as can be seen, are designed as springy or elastic, preferably cut-out projections that extend along the longitudinal extent of the guide walls 172, 173 and each have a free end. The locking projections 176 have locking lugs 177 at their free ends, which protrude in the direction of the locking recesses 37 in the assembled state and engage with the respective corresponding locking recess 37. The locking recesses 37 are preferably formed in the guide webs 36, but can alternatively also be formed in the guide walls 31.

When inserted or pushed into or onto the holding part 100, the locking projections 176 are pressed away from the respective leg 31, here inwards into the holding part 100, due to the contact of their locking lugs 177 with the opposite inner side of the respective leg 31 of the intermediate cover part 30. If the locking recesses 37 are located opposite the associated locking lugs 177, the locking projections 176 snap back in the direction of the respective locking recess 37, whereby the locking lugs 177 snap into the locking recesses 37 and thus prevent or make it more difficult for the intermediate cover part 30 to accidentally come loose from the holding part 100.

As in 6b As shown, the guide webs 36 open at their ends facing away from the ventilation slots 32 into projections 34, which are preferably designed to be springy or elastic and thus have free ends in this direction. These ends are designed to be thicker in the direction of the inside of the immediately adjacent leg 31 and preferably comprise lugs 35 protruding in this direction.

When inserting or pushing the intermediate cover part 30 into or onto the holding part 100, the projections 34 are pressed away from the guide web 175, here inwards into the holding part 100, due to the contact of their lugs 35 with the opposite side of the respective guide web 175 of the holding part 100. The projections 34 are thereby placed under prestress, which leads to a clamping effect between the clamping projections 34 or their clamping lugs 35 and the opposite guide web 175. This is indicated in 6a This will enable the 6 upper part of the intermediate cover part 30, ie the part facing away from the holding part 100, is held securely in position. As a result, the legs 31 advantageously come into contact with the holding part 100 or the cover hood(s) 20 arranged between them, preferably in a clamping manner. This has the advantage that any vibrations that could arise, for example, from the door operators when opening or closing the connected door leaves, do not result in the parts (20,) 30, 100 generating noises such as rattling or the like.

This means that the entire assembly consists only of sliding the intermediate cover part 30 onto the holding part 100, as shown in 6e indicated by the block arrow.

In particular 6a the guide edges 122 can alternatively or additionally be 3 also be formed by means of the surfaces of the guide walls 172 and/or 173 facing the immediately adjacent leg 31 of the intermediate cover part 30.

6c shows the intermediate cover part 30 and the holding part 100 from the sides that face each other when the intermediate cover part 30 is placed on the holding part 100.

As described above, the guide section of the intermediate cover part 30 comprises a substantially L-shaped wall section which is formed on the inside of the associated leg 31. Both wall sections are open on one and the same side, here to the left.

The guide section 121 of the holding part 100, as also described above, accordingly comprises a substantially complementary L-shaped wall section which, when the intermediate cover part 30 is placed on, is open in a direction opposite to the intermediate cover part 30. The two wall sections 39, 172 thus engage with one another when the intermediate cover part 30 is placed on and guide the intermediate cover part 30 along the holding part 100. This simplifies assembly enormously; the susceptibility to errors is enormously reduced.

Furthermore, as in 6d shown, clamping lugs 179 can also be formed on the holding part 100 opposite the locking lugs 177 and protruding towards them. The lugs 177, 179 thus facing each other narrow the space between them in such a way that in this area a quasi S-shaped cross-section of the space is created. The clamping lugs 179 are closer to the fastening section 110 than the locking lugs 177. When the intermediate cover part 30 (not shown here) is pushed on, its legs 31 are pushed apart by the locking lugs 177 as they move past and preferably snap back as soon as the locking lugs 177 are opposite the corresponding locking recesses 36. In this state, the free ends of the legs 31 have also been moved past the clamping lugs 179. These now push the free ends of the legs 31 towards each other and thus in the direction of the opposing locking lugs 177. This means that the clamping lugs 179 ensure that the locking lugs 177 are securely engaged with the locking recesses 37.

6e shows the intermediate cover part 30 and the holding part 100 before fitting in the direction of the block arrow. The locking lugs 177 are in accordance with 6a in the direction of the intermediate cover part 30, they are preferably tapered in such a way that they have a starting bevel for the guide webs 36 of the intermediate cover part 30. When pushed on, the locking lugs 177 can be easily pushed away from the guide webs 36 due to these bevels.

This means that the mounting of the intermediate cover part 30 merely consists in sliding it onto the holding part 100 until the locking lugs 126 engage or the intermediate cover part 30 comes to rest on the aforementioned support surface 124.

At least the first guide walls 172 preferably end flat in the direction of the longitudinal extension of the through opening 151 and thus form a support or a stop, for example, for a system carrier of an adjacent door operator. This makes it possible to push the holding part 100 directly up to the respective door operator.

7 shows the holding part 100 in connection with the aforementioned side panel 40 of 1 . The side panel 40 has fastening devices in the form of projections 43, 44 protruding in the direction of the holding part 100 on the side facing the holding part 100. They enclose, for example, a square with rounded corners. The projections 43 arranged in the corner areas of this square serve to guide the sliding of the side panel 40 onto the holding part 100. The sliding projections 43 thus formed are not straight in cross section but angled or, as shown here, viewed in the direction of the extension of the through opening 151, are concavely curved on the sides facing each other. The holding part 100 or its side panel fastening section 130 has essentially complementary, i.e. convex, guide sections 131 at corresponding points. The side panel 30 is therefore already positioned when it is pushed onto or into the holding part 100; only the insertion depth is not yet determined.

In order to be able to fix the side panel 40 in terms of the insertion depth, a locking mechanism is provided here. The arched design of the projections 43 hinders the flexible bendability of the projections 43. They are therefore rather unsuitable for a locking mechanism. For this reason, the aforementioned projections 44 are also provided, which are flat and springy in cross section. At their free ends, the locking projections 44 formed in this way have, for example, locking lugs 45 facing one another. When inserted into the holding part 100, the locking lugs 45 engage with corresponding locking recesses in the holding part 100. In the example shown, these locking recesses are formed by means of a respective locking groove section 132. Each locking groove section 132 comprises a plurality of locking grooves, not designated in more detail, which run parallel to one another and essentially transversely to the insertion direction of the side panel 40. This makes it possible to vary the insertion depth depending on the respective circumstances. In particular, longer cover hoods 20 are subject to certain manufacturing-related length deviations. The locking grooves allow compensation. If the cover hood 20 shorter or longer, the side panel 40 is simply pushed a little further or less far into the holding part 100 until, for example, it is flush with the cover hood 20.

7a shows side panel 30 and holding part 100 before assembly along the block arrow, and 7b shows a possible assembly state. 7c shows an enlarged section in relation to 7b Here, the locking engagement of the locking lugs 45 with a respective locking groove of two visible sections 132 can be seen particularly well.

Instead of several locking grooves, a locking recess corresponding to one of the locking lugs 45 can of course be formed, with the disadvantage of the lack of length compensation with respect to the cover 20.

This positioning mechanism allows assembly that only consists of sliding the side panel 40 into or onto the holding part 100. The fastening sections 43, 44, 131 ensure that the switches 51, 52 described above pass through the associated through openings 41 and, for example, the ventilation grille 42, as also described above, is aligned with the through opening 151 of the holding part 100 with regard to the cooling air flow.

7d shows the holding part 100 from a 7c opposite view, without side panel 40. As can be seen, the holding part 100 also has two recesses 133. These are from the right or left in 7d accessible in such a way that a tool such as a flat screwdriver or the like can be inserted, whereupon the side panel 40 can be levered off. This means that the recesses 133 represent a dismantling aid with regard to the side panel 40.

8th shows an upper part of the holding part 100, i.e. the part facing away from the mounting plate 10 (not shown), enlarged in a detail. As can be seen, the holding part 100 can also have at least one, here two, cable guide sections 140. The cable guide sections 140 are designed such that they each comprise at least one respective groove-like cable receptacle or recess 143. For this purpose, each cable guide section 140 has two wall sections 141, the surfaces of which facing each other are preferably designed to be parallel to each other or to converge in a predetermined direction, but are not less than a predetermined distance from each other. The wall sections 141 belonging to a cable receptacle 143 are connected to each other at one point by means of a groove base 144. In order to prevent the lines or cables laid therein from moving out of the respective receptacle 143 or to make this more difficult, at least one of the wall sections 141 has a clamping projection 142, here in the form of a nose, at its free end. The clamping projection 142 protrudes from the associated wall section 141 in the direction of the opposite wall section 141 of the receptacle 143. In the assembled state, the receptacles 143 preferably extend along a longitudinal extension of the mounting plate 10.

The guide section(s) 121 arranged in the direction of extension of the respective receptacle 143 preferably has a respective recess 126 which makes it possible to lay the lines or cables over these guide sections 121.

Alternatively, the guide sections 121 also have a respective cable guide section 140, or the associated cable guide section 140 extends over the respective guide section 121.

9a shows an air guide part 60 according to a second embodiment of the invention. This embodiment differs from the above-described first embodiment mainly in that the air guide part 60 has only one air guide section 61, which preferably has a width that corresponds approximately to the sum of the width dimensions of the air guide sections 61 and the air dividing section 67 according to the first embodiment. This means that this air guide part 60 is only able to be directed in the -x or -z coordinate direction in 9a to redirect the air striking the air guide part 60 in the +z or +x coordinate direction. This has the advantage that the attached cover 20 or the attached intermediate cover part 30, each not shown here, only needs to have ventilation slots 32 on one leg 21 or 31. The air guide part 60 can also be used rotated by 180° around the x coordinate axis, so that the air is directed to the left in 9a or from there is redirected to the air guide part 60. This offers the possibility of aligning the ventilation slots 32 so that they are invisible to users, i.e. in the direction of the ceiling or door frame, without affecting the cooling. This makes it possible to achieve cooling that is invisible to users. In addition, there is no draft underneath the door operator arrangement 1.

Furthermore, it is provided by way of example that the locking projections 66, of which only the lower one is visible, are continuous. Otherwise, there are again the cut-out arms 68 with locking lugs 65 at their free ends. The air guide section 61 again opens into a Rear wall 63. There are also preferably wall sections 62, of which only the lower one in 9a is visible.

Preferably, two side edges 63a pointing away from each other are formed on the air guide part 60. They form the lateral ends of the rear wall 63. Two side edges 63a make it possible to prevent both stop webs 127 of the holding part 100 from moving into the interior of the holding part 100, as described with reference to 4a described. This means that when the cover 20 is pushed on, both legs 23 would be bent away from the holding part 100.

9b shows an air guide part 60 according to a third embodiment of the invention. It is designed similarly to the second embodiment, i.e. it again has only one air guide section 61. This means that this air guide part 60 is again only able to be directed in the -x or -z coordinate direction in 9a to redirect air striking the air guide part 60 in the +z or +x coordinate direction. There are again free-standing arms 68 with locking lugs 65 at their free ends. The rear side is designed similarly to the air part 60 according to the first embodiment of the invention, i.e. it has two wall sections 64 with locking projections 66 formed thereon and extending at least in the ±y coordinate direction. As can also be seen, a separately formed rear wall is missing here, which simplifies the construction of the air guide part 60.

In this embodiment, for example, only one side edge 63a is formed.

The invention is not limited to the embodiments described above.

According to the invention, the holding part 100 has the previously described sections 110 and 120. In addition, it can have the sections 130, 140, 150 and 160 individually or in any combination with one another.

The switch part 50 is also only an example. It can also not have a switch 51, 52 but for example a display or the like. In this case, the associated side panel 40 has corresponding through openings for the exemplary display. Furthermore, the side panel 40 does not have to have a ventilation grille 42. In this case, the air is preferably discharged or redirected via the air guide part 60 described above.

The rear wall 63 can also be omitted so that the air guide sections 61 determine the external dimensions of the air guide part 60 in both the y and z coordinate directions. 4 and 9 determine.

A door operator arrangement 1 provided with at least one holding part 100 therefore has at least one door operator for the door leaf or leaves. In addition, it has at least one mounting plate 10, namely at least intended for the door operator, which in turn is known to be designed to hold the associated door operator and to be fixedly attached to a support body. It also has at least one cover 20 and at least one of the holding parts 100 described above.

A door operator assembly 1 equipped with such holding parts can be mounted very easily. 10 shows such an assembly method. After starting in step S1, the mounting plate(s) 10 of the door operator arrangement 1 is/are attached to the respective support body in a subsequent step S2. The door operator(s) is/are then attached to the respective mounting plate 10 in a step S3. If additional components such as a light curtain, radio module, radar detector or the like are to be mounted (yes branch after step S4), these are attached to the respective mounting plate 10 in a subsequent step S5 in the same way as the door operator(s). If all components are mounted, or if there are no additional components (no branch after step S4), the holding part(s) 100 to be attached is/are attached to the associated mounting plate 10 in a step S6, namely by placing it on and thereby fixing it (for example by screwing it into the mounting plate 10 as described above). In the case of electronic components, the assembly usually also includes their wiring. Finally, in a step S7, the cover(s) 20 are placed on the associated holding part 100 and, if applicable, the associated door operator. The assembly is then completed in a step S8. The result is an extremely simple and, in particular, safe assembly process.
